    1988-06-01

    Jordan is a country of 91,000 sq km, only 11% of which is arable. The 1980 population was 2.8 million, growing at 3.65% per year. Most of the people are of Arab stock, including between 1 and 1 1/4 million Palestinians. 95% of the people are Sunni Muslims. The national language is Arabic, and literacy is 71%. The infant mortality rate in 1984 was 50/1000, and life expectancy is 64 years. Suffrage is universal. The 1986 gross domestic product was $4.3 billion, per capita $1530; the growth rate was 2.6%. 80% of the people are employed in agriculture and 20% in industry. The major resources are phosphate and potash. The dinar is worth $0.35. Jordan's economy grew during the 1960s and 1970s, and it achieved the 10% growth rate called for in its 1st 5-year plan (1976-80). The 2nd 5-year plan saw a slow-down in the economy, and the 3rd 5-year plan aims at a growth rate of only 5.1% and the creation of 97,000 new jobs. A major weakness of the economy is its dependence on money from abroad -- $0.5 billion from other Arab countries, wages of expatriate Jordanians working in the Gulf states, and $1.7 billion in US aid between 1952 and 1987. 1986 exports amounted to $732 million, imports to $2.4 billion. Jordan was settled by Canaanites around 2000 BC and was ruled successively by Egyptians, Assyrians, Persians, Greeks, Romans, Turks, and from 1919 to 1946 Britain. The independent Hashemite Kingdom, a constitutional monarchy, was founded in 1946. War with Israel ended with the establishment of the present official border in 1949, but Israel has occupied the West Bank of the Jordan since 1967, and the militant pro-Syrian Palestinian fedayeen maintained a guerrilla war within Jordan until 1973. In 1974 King Hussein recognized the Palestine Liberation Organization as the sole representative of the Palestinian people. However, by reconvening Parliament in 1984 with representatives from the West Bank, the King contradicted his recognition of the claims of the Palestine Liberation Organization to represent all Palestinians. King Hussein has urged the Palestine Liberation Organization to accept UN Security Council resolutions 242 and 338 and renounce the use of violence. The November 1987 Arab League summit in Amman was a major victory for Hussein's diplomatic efforts. PMID:12177997

    Cancer is the second leading cause of death in Jordan after cardiovascular diseases. Due to increase in life expectancy and prolonged exposure to risk factors, cancer mortality and morbidity are expected to increase as the young population ages. This increase will constitute a challenging burden on healthcare systems in Jordan and many other neighboring countries. Planning is key to managing the expected rise in the demand for cancer care, and this will require public health initiatives to guarantee access to quality cancer care. Over the past decade, cancer care in Jordan has witnessed remarkable improvement through access to advanced diagnostics and therapeutics. In this review, we address the history of cancer care in Jordan, including cancer statistics, infrastructure, workforce as well as cancer care outcomes. We also discuss many of the challenges that we face and offer suggestions for the improvement of cancer management in Jordan and the region. PMID:25732671

    2009-01-01

    We consider the structure of Jordan H-pseudoalgebras which are linearly finitely generated over a Hopf algebra H. There are two cases under consideration: H = U(h) and H = U(h) # C[?], where h is a finite-dimensional Lie algebra over C, ? is an arbitrary group acting on U(h) by automorphisms. We construct an analogue of the Tits-Kantor-Koecher construction for finite Jordan pseudoalgebras and describe all simple ones.

  5. Relapsing fever in Jordan

    PubMed Central

    Babudieri, B.

    1957-01-01

    The author reports on a survey carried out by him in 1954 on relapsing fever in Jordan. In that country the disease is largely tick-borne, the main vector being Ornithodoros tholozani. Some of the frequent cases in the town of Nablus and the village of Marda in West Jordan may, however, be caused by O. coniceps. The centres of infection are some of the numerous caves scattered throughout the hilly areas and certain houses in which chickens are kept. It is believed that the vector ticks could be successfully exterminated by the use of insecticides and by the adoption of certain procedures outlined by the author. Arsenobenzol compounds and penicillin have been shown not to be very effective for the treatment of relapsing fever, but good results have been obtained with Aureomycin and Terramycin.

    2015-03-01

    State cones in orthodox quantum theory over finite dimensional complex Hilbert spaces enjoy two particularly essential features: homogeneity and self-duality. Orthodox quantum theory is not, however, unique in that regard. Indeed, all finite dimensional formally real Jordan algebras -- arenas for generalized quantum theories with close algebraic kinship to the orthodox theory -- admit homogeneous self-dual positive cones. We construct categories wherein these theories are unified. The structure of composite systems is cast from universal tensor products of the universal C*-algebras enveloping ambient spaces for the constituent state cones. We develop, in particular, a notion of composition that preserves the local distinction of constituent systems in quaternionic quantum theory. More generally, we explicitly derive the structure of hybrid quantum composites with subsystems of arbitrary Jordan algebraic type.

  12. Water scarcity in the Jordan River basin.

    PubMed

    Civic, M A

    1999-03-01

    This article reports the problem on water scarcity in the Jordan River basin. In the Jordan River basin, freshwater scarcity results from multiple factors and most severely affects Israel, Jordan, the West Bank, and the Gaza Strip. One of these multiple factors is the duration of rainfall in the region that only occurs in a small area of highlands in the northwest section. The varying method of water use parallels that of Israel that utilizes an estimated 2000 million cu. m. The national patterns of water usage and politically charged territorial assertions compound the competition over freshwater resources in the region. The combination of political strife, resource overuse, and contaminated sources means that freshwater scarcity in the Jordan River basin will reach a critical level in the near future. History revealed that the misallocation/mismanagement of freshwater from the Jordan River basin was the result of centuries of distinct local cultural and religious practices combined with historical influences. Each state occupying near the river basin form their respective national water development schemes. It was not until the mid-1990s that a shared-use approach was considered. Therefore, the critical nature of water resource, the ever-dwindling supply of freshwater in the Jordan River basin, and the irrevocability of inappropriate policy measures requires unified, definitive, and ecologically sound changes to the existing policies and practices to insure an adequate water supply for all people in the region.

    The Natural Resources Authority of Jordan (NRA), the USGS and LLNL have a collaborative project to improve the calibration of seismic propagation in Jordan and surrounding regions. This project serves common goals of CTBT calibration and earthquake hazard assessment in the region. These objectives include accurate location of local and regional earthquakes, calibration of magnitude scales, and the development of local and regional propagation models. In the CTBT context, better propagation models and more accurately located events in the Dead Sea rift region can serve as (potentially GT5) calibration events for generating IMS location corrections. The detection and collection of mining explosions underpins discrimination research. The principal activity of this project is the deployment of two broadband stations at Hittiyah (south Jordan) and Ruweishid (east Jordan). These stations provide additional paths in the region to constrain structure with surface wave and body wave tomography. The Ruweishid station is favorably placed to provide constraints on Arabian platform structure. Waveform modeling with long-period observations of larger earthquakes will provide constraints on 1-D velocity models of the crust and upper mantle. Data from these stations combined with phase observations from the 26 short-period stations of the Jordan National Seismic Network (JNSN) may allow the construction of a more detailed velocity model of Jordan. The Hittiyah station is an excellent source of ground truth information for the six phosphate mines of southern Jordan and Israel. Observations of mining explosions collected by this station have numerous uses: for definition of templates for screening mining explosions, as ground truth events for calibrating travel-time models, and as explosion populations in development and testing discriminants. Following previously established procedures for identifying explosions, we have identified more than 200 explosions from the first 85 days of recording. In addition, Hittiyah is being calibrated for coda magnitude estimation and is placed favorably to estimate mechanism and magnitude for earthquakes along the Dead Sea Rift and the Gulf of Aqaba.

  14. Baseline Characteristics of Jordan Creek, Juneau, Alaska

    Host, Randy H.; Neal, Edward G.

    2004-01-01

    Anadromous fish populations historically have found healthy habitat in Jordan Creek, Juneau, Alaska. Concern regarding potential degradation to the habitat by urban development within the Mendenhall Valley led to a cooperative study among the City and Borough of Juneau, Alaska Department of Environmental Conservation, and the U.S. Geological Survey, that assessed current hydrologic, water-quality, and physical-habitat conditions of the stream corridor. Periods of no streamflow were not uncommon at the Jordan Creek below Egan Drive near Auke Bay stream gaging station. Additional flow measurements indicate that periods of no flow are more frequent downstream of the gaging station. Although periods of no flow typically were in March and April, streamflow measurements collected prior to 1999 indicate similar periods in January, suggesting that no flow conditions may occur at any time during the winter months. This dewatering in the lower reaches likely limits fish rearing and spawning habitat as well as limiting the migration of juvenile salmon out to the ocean during some years. Dissolved-oxygen concentrations may not be suitable for fish survival during some winter periods in the Jordan Creek watershed. Dissolved-oxygen concentrations were measured as low as 2.8 mg/L at the gaging station and were measured as low as 0.85 mg/L in a tributary to Jordan Creek. Intermittent measurements of pH and dissolved-oxygen concentrations in the mid-reaches of Jordan Creek were all within acceptable limits for fish survival, however, few measurements of these parameters were made during winter-low-flow conditions. One set of water quality samples was collected at six different sites in the Jordan Creek watershed and analyzed for major ions and dissolved nutrients. Major-ion chemistry showed Jordan Creek is calcium bicarbonate type water with little variation between sampling sites.

  15. The Thermal Waters of Jordan

    Sass, I.; Schäffer, R.

    2012-04-01

    In a recent field campaign all known natural hot spring areas of Jordan were investigated. Their hydrochemical properties including some fundamental isotopes were measured. Jordan's thermal springs can be classified into four thermal provinces (Nahr Al-Urdun, Hammamat Ma'in, Zara and Wadi Araba province), with similar hydrochemical and geologicalsettings. Thermal springs of Hammamat Ma'in and Zara province are situated on prominent faults. Reservoir temperature estimation with the Mg-corrected Na-K-Ca geothermometer indicates temperatures between 61 °C and 82 °C. Even taking into account the increased geothermal gradient at Dead Sea's east coast, the water's origin has to be considered mainly in deeper formations. Carbon dioxide, emitted by tertiary basalts situated close to the springs, may be responsible for gas lift. Mineralisation and ?18O-values indicate, that the spring water's origin is mostly fossil, i.e. not part of the global water cycle. It is shown, that ground water mining led to a shift within ?18O-ratio during the last 30 years due to a reduction of shallow water portion in addition to a dislocation of the catchment area. Ground water mining will impact the thermal spring productivity and quality anyway in the future. Present-day precipitation rates and catchment areas in Dead Sea region are by far not sufficient to explain relative high discharge. For the Hammamat Ma'in Province is documented, that discharge and maximal spring water temperatures are constant during the last 50 years, showing marginal seasonal oscillation and negligible influence by short-term climatic changes. The water characteristics of Hammamat Ma'in and Zara province are related. However, Zara waters feature systematically less ion concentration and lower temperatures due to a stronger influence of vadose water. The springs of Nahr Al-Urdun province are recharged mainly by shallow groundwater. Thus temperature and mineralisation is lower than at the springs at the Dead Sea. Thermal waters of Wadi Araba province show the lowest mineralisation due to their origin of mostly sandstones. The main ion's proportion and ?18O-ratio indicate a mixture of fossil and vadose groundwater.

  17. Pediatric oncology situation analysis (Jordan).

    PubMed

    Al-Rimawi, Hala Saleh

    2012-03-01

    This article highlights the current situation of pediatric oncology in Jordan by reviewing the available population based data from the surveillance. Cancer among children aged less than 15 years make up 4 to 6% of all registered new cancer cases in all ages each year. The major types of cancer in females for the year 2008 are leukemia 32.2%, central nervous system 18.8%, skeletal and soft tissue 8.8%, lymphomas 5.5%, and sympathetic 5.5%, whereas in males, they are leukemia 28.1%, central nervous system 18.8%, lymphomas 16.2%, skeletal and soft tissue 7% and sympathetic 6.3%. Children with cancer receive treatment through pediatric oncology wards in King Hussein Cancer Center (KHCC) and Royal Medical Services hospital or through pediatric departments in King Abdullah university Hospital and Princes Rahma hospital with full government coverage of the treatment expenses. Currently the pediatric palliative care program is limited to KHCC which provides inpatient care, and out-patients and drop-in care on a daily basis to provide symptom management, counseling, and other services as appropriate. The lack of palliative care in other hospital and pediatric home care coverage stress the need to develop special plan of action to initiate these services. PMID:22357144

  20. The Cretaceous/Paleogene boundary in Jordan

    NASA Astrophysics Data System (ADS)

    Farouk, Sherif; Marzouk, Akmal M.; Ahmad, Fayez

    2014-11-01

    The Cretaceous/Paleogene (K/Pg) boundary in Jordan is marked by a major depositional hiatus that differs in magnitude from place to place due to variable structural movements of the Syrian Arc Fold Belt that resulted in irregularity of Jordan/Levant depositional basin after the deposition of Maastrichtian succession. To elucidate the nature of this hiatus, fieldwork was carried out at a number of locations including lithofacies and stratigraphic analysis, and a multi-proxy study of microplanktonic biostratigraphy (calcareous nannofossilis and planktonic formaminifera). However, the duration of this hiatus extended over latest Maastrichtian and early Danian stages. This is based on the absence of the planktonic foraminifera; Pseudoguembelina hariaensis (CF3), Pseudoguembelina palpebra (CF2), Plummerita hantkeninoides (CF1), Guembelitria cretacea (P0), Parvularugoglobigerina eugubina (P&) zones and Parasubbotina pseudobulloides (P1a) subzones and the coeval calcareous nannofossils Nephrolithus frequens and Markalius inversus zones. We estimate that in the paleo-lows areas an unexpected 3.96 Ma hiatus is present. Conversely, in swell areas, the duration of the hiatus represents the entire Danian-Selandian interval and revealed an unexpected 10.33 Ma hiatus, especially in the central part of Jordan. Subsequently, a marked transgression took place over the whole of Jordan which resulted in the prevalence of deep water conditions (Zones P4 or equivalent NP7/8); this caused the deposition of a retrogradational parasequence set of middle shelf pelagic marl and chalk during a rapid relative rise of sea-level. A correlative hiatus and time gap have also been reported in different parts of the Arabian and African plates, indicating that Jordan was influenced by regional tectonics that combined with the latest Maastrichtian sea-level fall resulted in a long-term sub-marine hiatus and/or non-deposition of sediments. A combination of sea level changes and tectonic uplift are the likely cause for such a long gap in the sediment record in the region.

  1. Disformal gravity theories: A Jordan frame analysis

    NASA Astrophysics Data System (ADS)

    Sakstein, Jeremy; Verner, Sarunas

    2015-12-01

    The Jordan frame action for general disformal theories is presented and studied for the first time, motivated by several unresolved mysteries that arise when working in the Einstein frame. We present the Friedmann equations and, specializing to exponential functions, study the late-time cosmology using both dynamical systems methods and by finding approximate solutions. Our analysis reveals that either the disformal effects are irrelevant or the Universe evolves towards a phantom phase where the equation of state of dark energy is -3 . There is a marginal case where the asymptotic state of the Universe depends on the model parameters and de Sitter solutions can be obtained. Our findings indicate that the metric singularity found using the Einstein frame construction corresponds to phantom behavior in the Jordan frame and we argue that this is the case for general disformal theories.

    Abstract Problem Before 2003 there was substantial underreporting of deaths in Jordan. The death notification form did not comply with World Health Organization (WHO) guidelines and information on the cause of death was often missing, incomplete or inaccurate. Approach A new mortality surveillance system to determine the causes of death was implemented in 2003 and a unit for coding causes of death was established at the ministry of health. Local setting Jordan is a middle-income country with a population of 6.4 million people. Approximately 20?000 deaths were registered per year between 2005 and 2011. Relevant changes In 2001, the ministry of health organized the first meeting on Jordan’s mortality system, which yielded a five-point plan to improve mortality statistics. Using the recommendations produced from this meeting, in 2003 the ministry of health initiated a mortality statistics improvement project in collaboration with international partners. Jordan has continued to improve its mortality reporting system, with annual reporting since 2004. Reports are based on more than 70% of reported deaths. The quality of cause-of-death information has improved, with only about 6% of deaths allocated to symptoms and ill-defined conditions – a substantial decrease from the percentage before 2001 (40%). Mortality information is now submitted to WHO following international standards. Lessons learnt After 10 years of mortality surveillance in Jordan, the reporting has improved and the information has been used by various health programmes throughout Jordan. PMID:26600615

    In 1985, a collaborative research program was established between the Royal Scientific Society of Jordan and Environment Canada, Pollution Measurement Division, Ottawa, Canada, with the objective of developing an air pollution monitoring network for Amman and preparing recommendations for national air quality standards and national emission standards for Jordan. Four monitoring sites were established in residential and commercial areas of Amman. Carbon monoxide, nitrogen dioxide, sulphur dioxide and total suspended particle matter (TSP) were measured at the Downtown station. At the other sites only TSP was measured. A short-term monitoring program carried out with a mobile monitoring unit showed relatively low levels of sulfur dioxide, carbon monoxide and nitrogen dioxide at the RSS, Naser and Marka sites as compared to the Downtown site. Continuous analyzers purchased from Environment SA, France, were used to measure sulfur dioxide, carbon monoxide and nitrogen dioxide; Sierra-Anderson high volume samplers equipped with glass fiber filters were used to collect total suspended particulates samples. Gaseous pollutants were continuously measured at the Downtown site and TSP samplers were operated on a three day schedule at all sites. Sampling began in July 1986 and continues to the present.

    The bubble nucleation rate in a first-order phase transition taking place in a background Jordan-Brans-Dicke cosmology is examined. The leading order terms in the nucleation rate when the Jordan-Brans-Dicke field is large (i.e., late times) are computed by means of a Weyl rescaling of the fields in the theory. It is found that despite the fact that the Jordan-Brans-Dicke field (hence the effective gravitational constant) has a time dependence in the false vacuum at late times the nucleation rate is time independent.

  20. Pascual Jordan, Varying Gravity, and the Expanding Earth

    2015-06-01

    In the 1950s, surprising links were proposed between cosmological theory and the geological and paleontological sciences. These links were mainly provided by Paul Dirac's hypothesis of 1937 that the gravitational constant G decreases with cosmic time. Pascual Jordan, famous for his pioneering contributions to quantum theory, took up Dirac's hypothesis; after the end of World War II, Jordan developed its geophysical consequences, concluding that the Earth is expanding. Much of Jordan's later scientific work focused on the expanding Earth and other aspects of the earth sciences relating to the varying- G hypothesis. This chapter in the history of science has received almost no attention from either scientists or historians. The article analyzes Jordan's cosmo-geological work in relation to the somewhat similar efforts of other "expansionists" in the period that led to the plate tectonic revolution in the earth sciences.

    This article reports that Syria and Jordan, two of the smaller producers in the Middle East, are starting to expand exploration and production activity. Syria, traditionally a producer of small volumes of heavy crude, is further developing its first light crude reservoir. The new Tayyim field is producing around 60,000 b/d and an expansion program should increase output to 100,000 b/d early next year. Heavy crude production will average about 180,000 b/d this year. Jordan, which previously relied on imports to meet all local demand, has its first discovery. The Hamzah field is now making a modest contribution to local refinery requirements. Gas has also been found in the northeast of Jordan, close to the border with Iraq. This article provides details of these projects.

    Poliomyelitis is endemic in Jordan, but until 1978 there were no epidemics. In that year, 66 children were admitted to the Jordan University Hospital with a paralytic illness, compared with 13 in 1979 and 11 in 1980. The epidemic reached a peak in the summer and fall of 1978. While 54% of the patients had not received any vaccine, 19% had received 3 doses of oral poliovaccine; 82% of the cases were in children less than 2 years of age, and all belonged to the lower socioeconomic group. There were 28 deaths with complications of the disease. Poliovirus was isolated from 10 out of 14 rectal swab samples examined (9 with poliovirus 1, 1 with poliovirus 2), and from 4 out of 13 throat specimens from the same patients. It is concluded that as a result of improving living standards in Jordan and neighbouring countries, more epidemics may occur unless immunization efforts against poliomyelitis are intensified.

    Recent geochemical and hydrological findings show that the water quality of the base flow of the Lower Jordan River, between the Sea of Galilee and the Dead Sea, is dependent upon the ratio between surface water flow and groundwater discharge. Using water quality data, mass-balance calculations, and actual flow-rate measurements, possible management scenarios for the Lower Jordan River and their potential affects on its salinity are investigated. The predicted scenarios reveal that implementation of some elements of the Israel-Jordan peace treaty will have negative effects on the Jordan River water salinity. It is predicted that removal of sewage effluents dumped into the river (???13 MCM/a) will significantly reduce the river water's flow and increase the relative proportion of the saline groundwater flux into the river. Under this scenario, the Cl content of the river at its southern point (Abdalla Bridge) will rise to almost 7000 mg/L during the summer. In contrast, removal of all the saline water (16.5 MCM/a) that is artificially discharged into the Lower Jordan River will significantly reduce its Cl concentration, to levels of 650-2600 and 3000-3500 mg/L in the northern and southern areas of the Lower Jordan River, respectively. However, because the removal of either the sewage effluents or the saline water will decrease the river's discharge to a level that could potentially cause river desiccation during the summer months, other water sources must be allocated to preserve in-stream flow needs and hence the river's ecosystem. ?? 2005 Elsevier Ltd.

    A comparative study is undertaken that brings to light the two different methods of how to treat the many-body problem in quantum field theory. The two main researchers who published the first versions of how to quantize a many-body assembly were P. Jordan and P.A.M. Dirac. What they understood by the so-called "second quantization" will be the subject of the paper. We will argue that it is Jordan's field operator approach that until now constitutes the basis of any work in quantum field theory.

    This study examined the prevalence of intimate partner violence in Jordan among a sample of 517 reproductive health clinic attendees. Intimate partner violence was measured using the World Health Organization's domestic violence questionnaire which was modified by the results of focus group discussions conducted in Amman. The percentages of women experiencing at least 1 form of control or violence since marriage were: control, 97.2%; psychological violence, 73.4%; physical violence, 31.2%; and sexual violence, 18.8%. Modifications of the WHO questionnaire were needed to measure control and psychological violence in Jordan. Similar modifications might be required when conducting research in the Region.

    This paper presents the petrographic and mineralogical characterization of mortars from different archaeological sites in Jordan which encompass Nabatean, Late-Antique and Early Islamic (Umayyad) sites, in some cases offering a sequence of different period mortars from the same building. These sites include the Nabataean city of Petra, the Late Antique town of Umm al Jimal and the castle of Qasr Al Hallabat. These mortars were produced with different raw materials and manufacturing technologies, which are reflected on distinctive variations of mineralogy, texture and crystal size and aggregates composition (including volcanic ashes, ceramic fragments, burnt organic material) size and their puzzolanic properties. As a consequence these mortars present different physical properties and reveal nowadays very different states of conservation. There is a dramatic change in mortar properties between those manufactured in pre-Islamic period and those from early Islamic - Ummayad times with a general trend in which these last ones present coarser crystal and aggregate sizes with less puzzolanic aggregates that result in less durable mortars. All of this reflects changes in the different stages of production of the mortar, from the use of either hydraulic, lime putty or slaked lime and the selection of aggregates to the application techniques (polishing). This reflects the evolution of building technology that took place in this area during early Islamic period and how petrological information can shed light on historical interpretation of building technologies.

    Noise defined as any sound that annoys or disturbs humans or that causes or tends to cause an adverse psychological and physiological effect on humans. Irbid is one of the most populated cities in Jordan. It is environmentally noise polluted due to the rapid and widespread introduction of mechanical methods for production and for their transportation. L10, L50, L90 and LAeq noise levels were measured during the day time and night time to assess and evaluate the noise levels from mosques, schools, celebration halls, streets, building works, industrial areas and commercial areas. The results of the investigation showed that the measured noise levels from all the selected sources were high during the day time and the noise problem is not only limited to day time, but continues in night time in this city. These noise levels were higher than those set by Jordanian limits during day time and night time. A significant correlation between the measured statistical noise levels L10, L50 and L90 and equivalent continuous noise level LAeq were also detected. The mean value of industrial noise source was motors of large vehicles and engines. Whereas the presence of slow moving vehicles, low speed and honking of horns during traffic ingestion periods lead to an increase in noise levels in commercial areas. The noise from building machines and equipment (dredges, concrete mixers, concrete pumps and jackhammers) is quite different from that of traditional equipment. The construction machines have engines that produce a loud, fluctuating noise with varying frequencies that can propagate the sound for a long distance. The noise produced by these engines is particularly disturbing due to the wide variations in frequency and volume.

    BACKGROUND/OBJECTIVES Two national surveys were conducted in Jordan in 2002 and 2010 to investigate the micronutrient status in women and children. To determine the prevalence of anemia, iron and folate deficiency among women and children in 2010 and compare with the prevalence of anemia and iron deficiency in 2002. SUBJECTS/METHODS A nationally representative survey was conducted in 2002 (1023 women, 15–49 years of age; 1059 children, 12–59 months of age) and a second survey in 2010 (2035 women; 940 children). Venous blood samples were used to measure hemoglobin, ferritin and red blood cell folate (the latter on a subsample of 393 women). RESULTS Among women in 2010, the prevalence of folate deficiency and insufficiency was 13.6% and 82.9%, respectively. Geometric mean serum ferritin was higher in 2010 compared with 2002 (21.3 ng/ml vs 18.3, P = 0.01); there was no significant change in the prevalence of iron deficiency (35.1% vs 38.7%, P = 0.17), iron deficiency anemia (19.1% vs 20.0%, P = 0.61) or anemia (29.2% vs 29.3%, P = 0.96). Among children, a significantly lower prevalence was observed in 2010 compared with 2002 for iron deficiency (13.7% vs 26.2% P < 0.001) and iron deficiency anemia (4.8% vs 10.1%, P < 0.001); a nonsignificant lower prevalence was observed for anemia (16.6% vs 20.2%, P = 0.09). CONCLUSIONS In 2010, approximately one of seven women was folate deficient and six out of seven were folate insufficient for the prevention of neural tube defects. Between 2002 and 2010, significant improvement was observed in the prevalence of iron deficiency in children, but not in women. PMID:24986824

    Network of Expertise for the Global Environment, a group representing 8 of the world`s leading electric utilities, in partnership with Jordan Electricity Authority (JEA), the national electric utility in the Hashemite Kingdom of Jordan, completed a project to establish an environmental management program at JEA. The project had two objectives: (1) to assist JEA in setting up an environmental management system to deal with environmental issues and to ensure compliance with regulations and standards, and (2) to conduct an environmental effects review at Jordan`s two largest electric generating facilities. The first objective was addressed by linking environmental issues at JEA, as determined by the environmental effects review, interviews and reports, to the draft ISO 14001 environmental management system specification. Use of ISO 14001 provided an internationally accepted standard that will assist JEA in fulfilling requirements of funding agencies. Seminars on environmental awareness and environmental auditing were delivered to support implementation of the environmental management system. The environmental effects review applied environmental auditing techniques to review environmental effects of JEA`s thermal power stations. The review provided a clear assessment of priorities for action as JEA established an environmental management program. A technical report and seminar on management of air emissions-immissions, a priority issue for JEA, were provided to complement the review.

    In this paper we establish the Jordan Form for a matrix using the elementary concepts of vector differentiation and partial fractions. The idea comes from the resolvent of the operator. For the matrix, the Laurent series is finite and easy to compute through rational representation. We also give a proof of some famous theorems in matrix analysis as consequences from the result.

  17. Distribution of Upper Pliocene brines in the northern Jordan Rift Valley, Israel and Jordan

    NASA Astrophysics Data System (ADS)

    Siebert, Christian; Möller, Peter; Rosenthal, Eliyahu; Guttman, Joseph; Yellin-Dror, Annat; Inbar, Nimrod; Magri, Fabien

    2014-05-01

    In the triangle of Lake Tiberias (LT), Yarmouk Gorge and Lower Jordan Valley (Fig. 1), fresh groundwaters are frequently deteriorated by variable admixture of ascending subsurface Upper-Pliocene brines. Element ratios and water isotopes reveal, that common source brine is present and is modified by water rock interaction and dilution with freshwater. This common source brine is inferred from the composition of the known Ha'on well brine being characterized by molar ratios of Na/Cl=0.53, 1000Br/Cl=5.5 and Ca/Mg=0.39 (Möller et al., 2011). The low Ca/Mg, a ratio also found for Newe Ur, is unique in an environment in which ratios >1 dominate because of omnipresent dolomitization of abundant limestones. Interaction with abundant intrusive basaltic bodies would add sodium and hence increase the low Na/Cl ratio to >1. Uptake of halite increases Na/Cl but decreases Br/Cl ratios. These ratios resemble seawater after 37-fold enrichment in Li molality by evaporation (McCaffrey et al. 1987). Although being diluted by freshwater the Ha'on well brine proves the presence of an evaporated seawater mother brine residing at unknown depth. The derivatives of inferred Ha'on mother brine are present around Lake Tiberias, in the lower Yarmouk Valley and in the northern Rift Valley at least as far southwards as Newe Ur. Areas of structural weakness, where the major fault systems occur, are the main distribution areas for these brines. The study provides an example whereby hydrochemical analyses are applied as key tool to better understand deep fluid transport processes at basin-scale, which are supported by numerical modeling of groundwater flow.

    The close connection between Jordan and Lie algebras makes these Jordan structures of interest to physicists. The Freudenthal-Tits Magic Square, which exemplifies this connection, has recently entered into constructing supergravity. We show how Jordan pairs-which are, from several points of view, a most natural Jordan structure-are imbedded in the Magic Square. We compare our approach with that of Gürsey and show show the Hermitian symmetric spaces parametrized by the scalars of N=2, d=4 supergravity theories are related either to Jordan pairs or to geometries of projective dimension two, whose elements belong to a Jordan pair.

    We study Bell inequalities and EPR states in the context of Jordan algebras. We show that the set of states violating Bell inequalities across two operator commuting nonmodular Jordan Banach algebras is norm dense in the global state space. It generalizes hitherto known results in quantum field theory in several directions. We propose new Jordan quantity for incommensurable observables in a given state, introduce the concept of EPR state for Jordan structures, and study relationship between EPR states and Bell correlated states. Our analysis shows crucial role of spin factors and Pauli spin matrices for studying noncommutative properties of states and observables.

    Khalaf, I; Callister, L C

    1997-12-01

    This descriptive, ethnographic study focuses on the experience of childbirth for Muslim women living in Jordan. Thirty-two childbearing women were interviewed in the early postpartum weeks. The audiotaped interviews were transcribed and translated. Themes were identified from the rich, narrative data. Motivations for having children, as well as what constitutes the motherhood feeling, were described. Themes also included the importance of relying on God or Allah for support in childbearing and child rearing. A strong sense of the spiritual dimensions of giving birth within women's traditional, religious, and cultural context was identified. Findings from this study provide insight into the meanings of childbirth for Muslim women living in Jordan. These meanings assist nurses in providing culturally competent care. PMID:9397746

  2. Worker programs and resource use: Evidence from better work jordan

    NASA Astrophysics Data System (ADS)

    Robins, Nathan

    This paper examines data collected for the Better Work program in Jordan which aims to protect laborers in the garment industry from poor working conditions. Data are examined to look for benefits to the factories participating in the program beyond improved compliance with labor law. In particular, potential impacts to firm energy use are examined and correlations are tested between electricity use rates and measures of worker outcomes and a number of factory traits such as size and production input costs. Evidence was found to back up work done in Vietnam with regard to resource use and distribution of electricity expenses. It was also found that the type of data being collected is not ideal for examinations of energy, and more direct methods are desirable, and that considerable production obstacles are worker skill level, electricity prices, and to a greater degree in Jordan than in previously examined countries, water prices.

  3. Soil erosion and land degradation in the Highlands of Jordan

    The Highlands of Jordan has a Mediterranean type of climate characterized by hot dry summers and cold wet winters. Unsustainable land use practices, recurrent droughts and climate change are the main causes of land degradation in the Highlands area of Jordan. Unsustainable land use practices include improper plowing, inappropriate rotations, inadequate or inexistent management of plant residues, overgrazing of natural vegetation, forest cutting, land fragmentation and over-pumping of groundwater. In addition, Jordan's rapid population growth (2.8% per year) is exerting considerable pressure upon its limited arable land through uncontrolled and random urbanization activities. Water erosion is the most widespread Land degradation type in the country. It greatly increases on slopes where the vegetation cover is (seasonally) reduced. It is further aggravated by a loss of soil structure and reduced infiltration rates. Wind erosion occurs most frequently in the arid and semi-arid portions of the southern Highlands, especially in areas with sandy or loamy soils. Rangeland degradation is the second most widespread land degradation type that is driven by overgrazing. The impact of overgrazing on the vegetation is evident from the excessive uprooting of the green matter (grass and bushes), leading to reduced seeding, reduced regeneration, and the consequent loss of plant cover which make the soil more susceptible to water and wind erosion. It is estimated that about 41 percent of Jordan's total land area is characterized as degraded of which 22 percent of the total land mass is classified as moderately degraded and agricultural productivity is greatly reduced. Observed aspects of land degradation include the recession of forest areas, high rate of erosion by water (formation of rills and gullies), expansion of urbanized area, reduction in soil organic matter and soil structure deterioration. Implementation of soil erosion control measures such as contour cultivation, terracing, management of crop residues, and stonewalls construction helped in reducing erosion.

    This survey was designed to enhance cancer prevention and care in a sample from the Arab world. A descriptive survey research design was adopted. A representative sample of 3,196 individuals from the three main regions of Jordan (north, middle, and south) was used. Data were collected through interviews. The tool for the study included the following aspects: identification and background information; health status; participant's lifestyle; general beliefs about cancer prevention; screening and early detection; and communication channels and seeking information about cancer. The participants believed that the three greatest factors related to cancer specifically in Jordan were active cigarette smoking, exposure to radiation, and exposure to chemicals. The majority of the participants agreed that getting regular cancer checkup helps diagnose the disease early with a good prognosis. Interestingly, cancer checkup was about seven times greater among females than males. Married individuals performed checkup four times more than singles. The findings indicate that knowledge gaps and improper practices toward cancer existed among the participants and, if corrected, could facilitate the care, prevention, and early detection of cancer. The findings help in defining key areas that should be addressed in national cancer policies in Jordan. PMID:24989815

    Food insecurity—not having sufficient quantities of good-quality foods—is inversely related to physical and mental health and directly related to poor dietary intake. The objectives of this research were to (a) measure the prevalence of food insecurity among women in northern Jordan, (b) study the socioeconomic factors associated with an increased risk of food insecurity, and (c) investigate the relationship between household food insecurity and women's reported body-weight. This cross-sectional study was conducted using an interview-based questionnaire. In total, 500 women were interviewed in the waiting rooms of the outpatient clinics of two major public hospitals in northern Jordan. Food insecurity was assessed using the short form of the U.S. food security survey module. The prevalence of food insecurity was 32.4%. Income below the poverty-line, illiteracy, unemployment, rented housing, and woman heading the household were among the socioeconomic factors that increased the probability of food insecurity. No evidence was found to support the relationship between obesity and food insecurity. Except grains, food-insecure women with hunger had lower intake of all food-groups. This study demonstrated that the problem of food insecurity is present in Jordan. Food-insecure women with hunger are at a risk of malnutrition. Interventions that target reduction of the factors associated with food insecurity are necessary. PMID:22524119

    To understand the biomolecular charcteristics of Bacillus anthracis in Jordan, 20 blood smear slides from dead animals with suspected anthrax were analyzed using conventional and molecular approaches. All slides were positive for B. anthracis by conventional staining but no growth of the organism on selective media was detected. However, of the 20 samples, 16 were B. anthracis DNA-positive using polymerase chain reaction (PCR). Seven samples provided enough quantity and quality of DNA, and their multilocus variable tandem repeat analysis (MLVA)-15 loci analysis revealed two different genotypes. All genotypes were belonging to A.B..r. 008/009 which is very common in Asia and Europe. Single nucleotide repeat (SNR) analysis revealed that there were no sub genotypes. Molecular diagnosis of animal anthrax in Jordan is not used routinely; henceforth, official diagnosis of anthrax is based on the observation of the slides by optical microscope and this can often cause reading errors. Therefore, the prevalence of the disease in Jordan might be slightly lower than that reported by the official bodies. PMID:26156620

  8. Assessing the Vulnerability of Agriculture to Climate Change in Jordan

    NASA Astrophysics Data System (ADS)

    Khresat, Sa'eb; Shraidaeh, Fadi; Maddat, Amer

    2015-04-01

    Climate change represents one of the greatest environmental, social and economic threats facing Jordan. In particular, the combined effects of climate change and water scarcity threaten to affect food and water resources that are critical for livelihoods in Jordan. This is especially true for those communities who live in the dryland area in the country and who rely wholly on rain-fed agriculture. The exact nature and extent of the impact of climate change on temperature and precipitation distribution pattern remain uncertain and it is the poor and vulnerable who will be the most susceptible to climate change adverse effects. A vulnerability assessment of rain fed agriculture to climate change and variability in semi-arid parts of Jordan was conducted in 2014. The purpose of this study is to assess the vulnerability and resilience of the most vulnerable groups where rainfed and irrigated agriculture is practiced. Also, the study focused on quantifying the impacts on agricultural productivity in response to climate change. This will help policymakers and researchers better understand and anticipate the likely impacts of climate change on agriculture and on vulnerable communities in Jordan. Also, it will provide them with tools to identify and implement appropriate adaptation strategies. The data used includes; Representative Concentration Pathways (RCPs), RCP 4.5 and RCP 8.5 adopted by the IPCC for its fifth Assessment Report (AR5). Those pathways were used for climate modeling. A decision support system (DSSAT) for agricultural production was used to assess the impact of climate changes on agricultural production. This approach was used for the Identification of climate change risk and their impacts on Agriculture. Outputs from models are used to assess the vulnerability of farmers and crops to climate and socio-economic change by estimating their sensitivity and capacity to adapt to external factors as a means of identifying what causes the differences in their vulnerability. Based on the projection models for the area, average temperature in Jordan is projected to increase between 1.2 and 1.6°C by 2050. These upward temperature trends are projected to continue beyond 2050. Projections for precipitation trends are projected to decrease by 16% by the year 2050. Evaporation is likely to increase due to higher temperatures. This is likely to increase the incidence of drought potential since precipitation is projected to decrease. It is concluded that the Overall vulnerability of agriculture to climate change in Jordan is high, where impacts such as drought and increased temperatures and decreased precipitation will be more pronounced. Major implications on rain fed agriculture are possible shorter growing season, increasing moisture and heat stress to field and horticultural crops and eventually low income and food insecurity. There were different impacts among studied communities, which is related to the: economic capability, local knowledge, physical infrastructure, institutional capacity, modern technology used, age group of farmers and diversification of their income.

  9. Sediment fingerprinting in Northern Jordan - approaching sediment comparability

    2014-05-01

    Jordan has a quantitative and qualitative water problem in combination with a growing demand by population increase. Around 65% of the freshwater used in Jordan is reported to originate from surface waters and reservoirs. Sediment loads harm the quality of these water bodies and fill up dams. A sediment fingerprint pilot study was implemented in an exemplary catchment in the NW of Jordan to investigate the possibility of geochemical differentiation between 6 sediment sources and calculate their relative contribution to the sink, the Wadi Al-Arab reservoir. The sediment fingerprint method relies on the comparability of sediment properties of the sources and the sink. However, selection processes during transport, preferential adsorption of elements on fine particles, and differences in inorganic carbonate content prevent a direct comparison. In previous studies this has been solved through selective sampling and analyzing certain grain size fractions or the mathematical derivation of correction factors. As no pre-knowledge existed in the Wadi Al-Arab catchment, selective grain size sampling would have implied the risk of neglecting important information already during the sampling process. Hence, a method was established that includes several steps to identify influential parameters (IPs), eliminate their impact and take account of their interrelations. It is based on a stepwise multiple regression analysis model (SMRAM) and generates element specific correction factors that take account for possible interdependencies between influential parameters as clay percentage and total organic and inorganic carbonates. In the further selection process of suitable elements for the fingerprint, we complemented the common used methods by a solubility analysis. Therefore, water profiles were physicochemical investigated in the dam lake. Differences in the chemical milieus during transport and sedimentation that affect the conservativeness of the chosen elements could be detected and taken account for. The study showed that common fingerprint elements and practices would have led to misinterpretations in the Wadi Al-Arab catchment and calls for a sound knowledge on catchment characteristics before the implementation of such a method.

  10. Radionuclides, trace elements, and radium residence in phosphogypsum of Jordan

    2011-01-01

    Voluminous stockpiles of phosphogypsum (PG) generated during the wet process production of phosphoric acid are stored at many sites around the world and pose problems for their safe storage, disposal, or utilization. A major concern is the elevated concentration of long-lived 226Ra (half-life = 1,600 years) inherited from the processed phosphate rock. Knowledge of the abundance and mode-of-occurrence of radium (Ra) in PG is critical for accurate prediction of Ra leachability and radon (Rn) emanation, and for prediction of radiation-exposure pathways to workers and to the public. The mean (??SD) of 226Ra concentrations in ten samples of Jordan PG is 601 ?? 98 Bq/kg, which falls near the midrange of values reported for PG samples collected worldwide. Jordan PG generally shows no analytically significant enrichment (< 10%) of 226Ra in the finer (< 53 ??m) grain size fraction. Phosphogypsum samples collected from two industrial sites with different sources of phosphate rock feedstock show consistent differences in concentration of 226Ra and rare earth elements, and also consistent trends of enrichment in these elements with increasing age of PG. Water-insoluble residues from Jordan PG constitute <10% of PG mass but contain 30-65% of the 226Ra. 226Ra correlates closely with Ba in the water-insoluble residues. Uniformly tiny (< 10 ??m) grains of barite (barium sulfate) observed with scanning electron microscopy have crystal morphologies that indicate their formation during the wet process. Barite is a well-documented and efficient scavenger of Ra from solution and is also very insoluble in water and mineral acids. Radium-bearing barite in PG influences the environmental mobility of radium and the radiation-exposure pathways near PG stockpiles. ?? 2010 US Government.

    During a flood of a magnitude that recurs once in 100 years, boulders up to 1700 mm in size were transported in the Jordan and Meshushim Rivers, northern Israel. Bedload discharge rates were estimated for periods of 3-72 hr of peak flow by a combination of hydrologic and geomorphic methods. Bedload transport rate is proportional to unit stream power in excess of that necessary for initial motion, raised to the power 3/2, as has been shown for data on other rivers. PMID:16592661

    2015-01-01

    Objective Current regulations in Jordan state that antibiotics cannot be sold without a medical prescription. This study aimed to assess the percentage of pharmacies that dispense antibiotics without a medical prescription in the Kingdom of Jordan and identify and highlight the extent and seriousness of such practices among Jordanian pharmacies. Methods A prospective study was performed, and five different clinical scenarios were simulated at pharmacies investigated including sore throat, otitis media, acute sinusitis, diarrhea, and urinary tract infection in childbearing-aged women. Three levels of demand were used to convince the pharmacists to sell an antibiotic. Results A total of 202 total pharmacies in Jordan were visited in the present study. The majority of pharmacies (74.3%) dispensed antibiotics without prescription with three different levels of demand. The percentage of pharmacies dispensing antibiotics without a prescription for the sore throat scenario was 97.6%, followed by urinary tract infection (83.3%), diarrhea (83%), and otitis media (68.4%). The lowest percentage of antibiotic dispensing was for the acute sinusitis simulation at 48.5%. Among the pharmacies that dispensed antibiotics, the pharmacists provided an explanation as the number of times per day the drug should be taken in 95.3% of the cases, explained the duration of treatment in 25.7%, and inquired about allergies prior to the sale of the antibiotic in only 17.3%. Only 52 pharmacies (25.7%) refused to dispense any kind of antibiotics, the majority (61.5%) of this refusal response came from acute sinusitis cases, while the minority (2.4%) came from the sore throat cases. Conclusion The results of this study demonstrate that antibiotics continue to be dispensed without prescription in Jordan in violation with national regulations regarding this practice. The findings of this study could provide a layout for governmental health authorities to implement strict enfrorcment of national regulations regarding antibiotic dispensing in order to avoid the serious complications that could arise in the future as a result of such practices.

    2014-03-01

    We present a model for the electroweak interactions based on the commutative but non-associative exceptional Jordan algebra of Hermitian matrices valued on the octonions. By this means, we propose a construction of a gauge theory which take values in this algebra. Following closely the six-dimensional model proposed by D. Fairlie years ago and using a supergroup, we found a natural structure that provides the weak interaction action with some additional terms; we will briefly comment on their possible meaning.

    Fenethylline, commonly known by the trademark name 'captagon', is one of the most popular drugs of abuse among the young affluent communities of the Middle East. The Drug Control Department of the Public Security Directorate of Jordan has put captagon under control in the year 1988. Samples from 124 batches seized were analyzed by means of gas chromatograph-mass spectrometry (GC-MS). The analysis demonstrates the presence of amphetamine, caffeine and several other substances, besides, the absence of fenethylline. Based on GC-MS analytical data, comparisons were made between the various samples to determine the similarities and obtain inferences with respect to commonality of origin. PMID:15978343

  15. Late Ordovician (Ashgillian) glacial deposits in southern Jordan

    The Late Ordovician (Ashgillian) glacial deposits in southern Jordan, comprise a lower and upper glacially incised palaeovalley system, occupying reactivated basement and Pan-African fault-controlled depressions. The lower palaeovalley, incised into shoreface sandstones of the pre-glacial Tubeiliyat Formation, is filled with thin glaciofluvial sandstones at the base, overlain by up to 50 m of shoreface sandstone. A prominent glaciated surface near the top of this palaeovalley-fill contains intersecting glacial striations aligned E-W and NW-SE. The upper palaeovalley-fill comprises glaciofluvial and marine sandstones, incised into the lower palaeovalley or, where this is absent, into the Tubeiliyat Formation. Southern Jordan lay close to the margin of a Late Ordovician terrestrial ice sheet in Northwest Saudi Arabia, characterised by two major ice advances. These are correlated with the lower and upper palaeovalleys in southern Jordan, interrupted by two subsidiary glacial advances during late stage filling of the lower palaeovalley when ice advanced from the west and northwest. Thus, four ice advances are now recorded from the Late Ordovician glacial record of southern Jordan. Disturbed and deformed green sandstones beneath the upper palaeovalley-fill in the Jebel Ammar area, are confined to the margins of the Hutayya graben, and have been interpreted as structureless glacial loessite or glacial rock flour. Petrographic and textural analyses of the deformed sandstones, their mapped lateral transition into undeformed Tubeiliyat marine sandstones away from the fault zone, and the presence of similar sedimentary structures to those in the pre-glacial marine Tubeiliyat Formation suggest that they are a locally deformed facies equivalent of the Tubeiliyat, not part of the younger glacial deposits. Deformation is attributed to glacially induced crustal stresses and seismic reactivation of pre-existing faults, previously weakened by epeirogenesis, triggering sediment liquefaction and deformation typical of earthquake generated seismites. Deformation, confined to an area of not more than 4 km wide adjacent to the major fault zone, implies earthquake magnitudes of at least 6 (M o). The high authigenic chlorite content of deformed Tubeiliyat sandstones compared to undeformed ones is attributed to a post-seismic hydrothermal system driven by compactional dewatering and hydrofracturing of the bedrock which acted as a groundwater recharge area, supplied by subglacial meltwater from beneath the ice sheet. Fluid movement along glacial seismotectonically reactivated faults infiltrated the adjacent Tubeiliyat sandstones under pressure and elevated geothermal gradient, where chlorite was precipitated from solution.

  16. Early Bronze Age Dolmens in Jordan and their orientations

    Polcaro, A.; Polcaro, F.

    This work presents the results of a survey of dolmen fields of the Early Bronze I in Jordan, in the Wadi Zarqa Valley, started in October 2004 and still in progress. Our data show, with a very high statistical significance, that in many sites of the Early Bronze IA a large majority of dolmens were built oriented along the N-S direction. A first interpretative hypothesis of these results, based on the astronomical contents of the mythology of the nearby civilizations culturally connected to the Palestinian area, is suggested.

    Breast cancer is the most common cancer, and one of the leading causes of death for females in Jordan and many countries in the world. Studies have shown that delay in symptoms presentation, diagnosis or treatment would result in poor prognosis. There has been no published study from Jordan on delays in patient presentation, delays in diagnosis, or delays in treatment. Therefore, we conducted this study to assess these important quality indicators aiming to improve prognosis for breast cancer patients in Jordan. This project was a cross-sectional study on female breast cancer patients in Jordan. The total number of participants was 327. The proportion of patients with presentation delay, diagnosis delay, and treatment delay was 32.2%, 49.1%, or 32.4%, respectively. The main reported reasons for delay in presentation were ignorance of the nature of the problem (65.6%), limited/lack of knowledge that symptoms were suggestive of cancer diagnosis (16.7%), and misdiagnosis (16.7%). Predictors of delay and mean time for presentation, diagnosis, and treatment were identified. Our results reveal that breast cancer patients in Jordan are experiencing delays in presentation, diagnosis, and treatment. This could justify the advanced stages at diagnosis and poor outcomes for breast cancer patients in Jordan. We recommend revising the current early detection and down-staging programs in Jordan.

    An ethical analysis of Jordan's Clinical Research Law, which became effective in 2001, was performed. Accordingly, this paper discusses the major components, key strengths and weaknesses of this law. As an initial effort, the Law addresses important aspects of research ethics and, hence, should serve as an example for other Arab Countries in the Middle East. Unique aspects of the Law include the requirement that those conducting any study have insurance that can compensate for research injuries and a system of fines and punishments for noncompliance with the Law. There are, however, some key items missing in the Jordanian Law. For example, the Law does not mention the requirement of a favourable assessment of risks and benefits, the fair selection of subjects, or articles regarding the protection of the rights and welfare of children and other vulnerable subjects participating in research. The paper concludes with the suggestion that new amendments should be considered for future revisions of the Clinical Research Law in Jordan. PMID:18302540

    Objective To study the psychiatric morbidity in the northern part of Jordan and to determine the frequency distribution of various psychiatric disorders, for planning services. Method All records of 2,335 psychiatric patients attending the only psychiatric clinic in Northern part of Jordan during a ten-year period from 1984 to 1993 were extensively reviewed and subjected to computerized analysis. Diagnosis was made as per ICD-9. Results Out of the 2335 patients who attended the clinic, 55% were males and 45% were females. Those in the age group 25–44 recorded the maximum attendance. Among the male attendees of the clinic, schizophrenia was the commonest diagnosis(19.9%), while among females, affective disorders were the commonest(15.9%). Conclusion Schizophrenia was found to be the commonest diagnosis in general among attendance of the clinic for the ten-year research period, while anxiety disorders were the commonest diagnosis among attendance of the clinic for the year 1993.

    Background: This study has aimed to evaluate the level of knowledge about the first aid process among the university students in Jordan. Methods: The study population consisted of students of the 14 scientific and unscientific faculties at Yarmouk University, Jordan. Data were obtained via questionnaires from 883 students. Results: The majority of participants were females (65.9%) with mean age (standard deviation) of 19.9 (2.6) years. Only 29.2% of students had previous first aid experience. When asked, only 11% of students knew the normal respiration rate of an adult in 1 min. Results revealed that female students, having previous first aid experience, and being a student of the health sciences and scientific colleges were the only factors had significant statistical associations with better level of first aid knowledge. Conclusions: The students’ knowledge about first aid is not at an adequate level. It would be advisable that first aid course be handled as a separate and practical course at secondary school level.

  1. Jordan-Wigner approach to dynamic correlations in spin ladders

    2004-03-01

    We present a method for studying the excitations of low-dimensional quantum spin systems based on the Jordan-Wigner transformation. Using an extended random-phase approximation (RPA) scheme we calculate the correlation function of neighboring spin flips for the one-dimensional spin-1/2 chain which well approximates the optical conductivity of Sr2CuO3. We analyze several possible generalizations of the Jordan-Wigner approach to the two-leg spin-1/2 ladder. On the mean-field level the most accurate results are obtained when the spin operators are numbered in a meanderlike sequence. Calculation of the optical conductivity based on an extended RPA scheme for the meander-path approach yields very good agreement with a previous density matrix renormalization group evaluation. For polarization along the legs higher-order correlations are important to explain the weight of high-energy continuum excitations and we estimate the contribution of 4- and 6-fermion processes.

    This article analyzes the patterns and determinants of maternal health care utilization in Jordan, using data from the Jordan Fertility and Family Health Survey of 1983. The study focuses on the 2,949 women who had a child in the five years preceding the survey. Through multivariate analyses of differentials in the utilization of prenatal care and health care at delivery, the study assesses the effect of sociodemographic factors, including residence, education, parity, and standard of living. The coverage of maternal health care in Jordan is discussed in relation to the overall organization of health services, the various providers of care, and the role of cultural factors. PMID:1949100

  3. Salinization Sources Along the Lower Jordan River Under Draught Conditions

    The Lower Jordan River, once a flowing freshwater river, is suffering from an ongoing reduction of discharge and water quality. The river flows between the Sea of Galilee and the Dead Sea, an aerial distance of about 105 Km. The severe reduction is caused by an excessive exploitation of its sources and diversion of sewage and agricultural drainage into the river. The extreme low flows and low water quality threaten the natural existence of the river and its potential use for agriculture. In spite of its importance, little research has been done in the river. The objectives of the study were to measure the discharge and water composition along the river and to evaluate the main sources that control its flow and chemical characteristics. The hypothesis of the study was that interaction with subsurface flows significantly affects the river flow and chemical composition. The research is based on a detailed field study, which included flow rate measurements in the river and its tributaries, water sampling and analysis and mass balance calculations of water and solutes. A portable Acoustic Doppler Velocimeter (ADV) was used to measure velocities and bathymetry at different locations across the river sections. Due to accessibility constraints, a floating traverse construction, which enables the ADV's deployment from one bank of the river, was developed. It was found that flow rate ranges between 500-1,100 L/s in northern (upstream) sections and 300-1,650 L/s in the south. This low discharge represents a significant reduction from historical values and is lower than recent published estimations. This research represents base flows only, as the measurements were done during a period of two consecutive draught years. Calculated mass balance of water flows in the northern sections shows that the subsurface source contributes to the river around 200-670 L/s (30-80% of the river flow). Calculations of solute balance show that the subsurface flows add 20-50% of the mass of solutes (e.g. Sulfate) that flows in the river. The assumption of a hydraulic gradient that points at inflows from subsurface flows is encouraged by high water levels measured in nearby piezometers. Possible natural subsurface sources include shallow groundwater or rising of water from deep formations. The existence of adjacent thermal wells strengthens the reasonability of such water rise. Possible anthropogenic sources include return flows and effluents. The results are consistent and agree with the geochemical and isotopic analyses. It is concluded that the impact of the subsurface component on the Jordan River is significant and must be taken into consideration, for future water management schemes and implementation of the Peace Treaty between Israel and Jordan.

  4. (Never) Mind your p's and q's: Von Neumann versus Jordan on the foundations of quantum theory

    Duncan, A.; Janssen, M.

    2013-03-01

    In 1927, in two papers entitled "On a new foundation [Neue Begründung] of quantum mechanics," Pascual Jordan presented his version of what came to be known as the Dirac-Jordan statistical transformation theory. Jordan and Paul Dirac arrived at essentially the same theory independently of one another at around the same time. Later in 1927, partly in response to Jordan and Dirac and avoiding the mathematical difficulties facing their approach, John von Neumann developed the modern Hilbert space formalism of quantum mechanics. We focus on Jordan and von Neumann. Central to the formalisms of both are expressions for conditional probabilities of finding some value for one quantity given the value of another. Beyond that Jordan and von Neumann had very different views about the appropriate formulation of problems in quantum mechanics. For Jordan, unable to let go of the analogy to classical mechanics, the solution of such problems required the identification of sets of canonically conjugate variables, i.e., p's and q's. For von Neumann, not constrained by the analogy to classical mechanics, it required only the identification of a maximal set of commuting operators with simultaneous eigenstates. He had no need for p's and q's. Jordan and von Neumann also stated the characteristic new rules for probabilities in quantum mechanics somewhat differently. Jordan and Dirac were the first to state those rules in full generality. Von Neumann rephrased them and, in a paper published a few months later, sought to derive them from more basic considerations. In this paper we reconstruct the central arguments of these 1927 papers by Jordan and von Neumann and of a paper on Jordan's approach by Hilbert, von Neumann, and Nordheim. We highlight those elements in these papers that bring out the gradual loosening of the ties between the new quantum formalism and classical mechanics. This paper was written as part of a joint project in the history of quantum physics of the Max Planck Institut für Wissenschaftsgeschichte and the Fritz-Haber-Institut in Berlin.

    This research characterizes marble chancel screens and their supporting columns, confiscated from treasure thieves, probably from northern Jordan in order to manage the most fruitful conservation and restoration interventions for them. It provides new archaeometric data and determines the probable source of the marbles. The results of mineropetrographic, X-ray diffraction and carbon and oxygen stable isotope analyses show that the marbles most probably are Proconnesian-1. The results agree with the historical records supported by archaeometric analyses that Proconnesos marble was widely used during the Roman and Byzantine periods for architectural purposes. The results suggest that color style of Proconnesian marble astonished the Byzantine stonemasons and architects thus have been widely used.

  6. Near infrared reflectance analysis by Gauss-Jordan linear algebra

    Near-infrared reflectance analysis (NIRA) is an analytical technique that uses the near-infrared diffuse reflectance of a sample at several discrete wavelengths to predict the concentration of one or more of the chemical species in that sample. However, because near-infrared bands from solid samples are both abundant and broad, the reflectance at a given wavelength usually contains contributions from several sample components, requiring extensive calculations on overlapped bands. In the present study, these calculations have been performed using an approach similar to that employed in multi-component spectrophotometry, but with Gauss-Jordan linear algebra serving as the computational vehicle. Using this approach, correlations for percent protein in wheat flour and percent benzene in hydrocarbons have been obtained and are evaluated. The advantages of a linear-algebra approach over the common one employing stepwise regression are explored.

  7. The quality of potable water types in Jordan.

    Four different potable water types: tap water, desalinated water in private plants, homes filtrated and sealed bottled water were collected from four provinces in Jordan and analyzed for various physiochemical parameters and trace metals content. The results showed that quality of potable water varied depending on many factors such as: water quality at source, types of purification system, and the storage methods. None of the analysed parameters exceeded the national and international guideline for potable water except Nickel (Ni). The maximum concentration of Ni was found in tap water which can be attributed as network distribution system and metal storage tanks influences. The highest levels of salinity was evident in tap water. Potable water produced at homes using different types of purification systems indicated lowest levels of salinity. Minor variations in physiochemical parameters and trace metal contents were found between local and imported bottled water brands. PMID:16917709

    Jordan, a high tobacco-burden country, has been working to expand its tobacco dependence treatment services and has completed development of its first customized treatment guidelines. Our paper presents the development process for these guidelines. A group of national and international experts was formed and a national situation analysis for tobacco dependence treatment practices and a detailed review of international evidence were conducted. The guidelines were then drafted and reviewed by national, regional and international experts and were official endorsed by the Jordanian Ministry of Health before being launched. The guidelines comprise concise descriptions and practical supplementary flowcharts covering the major elements of general tobacco dependence treatment. These are the first comprehensive Arabic-language guidelines, including a section focusing on waterpipe use, and we believe they are a reliable and useful resource for neighbouring countries seeking to develop similar guidelines.

    2013-10-01

    The Euclidean action with acceleration has been analyzed in Ref. 1, and referred to henceforth as Paper I, for its Hamiltonian and path integral. In this paper, the state space of the Hamiltonian is analyzed for the case when it is pseudo-Hermitian (equivalent to a Hermitian Hamiltonian), as well as the case when it is inequivalent. The propagator is computed using both creation and destruction operators as well as the path integral. A state space calculation of the propagator shows the crucial role played by the dual state vectors that yields a result impossible to obtain from a Hermitian Hamiltonian. When it is not pseudo-Hermitian, the Hamiltonian is shown to be a direct sum of Jordan blocks.

  10. Database compilation: hydrology of Lake Tiberias (Jordan Valley)

    A long-term series of water balance data over the last 50 years is compiled to gain insights into the hydrology of the Lake Tiberias (LT) and surrounding aquifers. This database is used within the framework of a German-Israeli-Jordanian project (DFG Ma4450-2) in which numerical modeling is applied to study the mechanisms of deep fluid transport processes affecting the Tiberias basin. The LT is the largest natural freshwater lake in Israel. It is located in the northern part of the Dead Sea Rift. The behavior of the lake level is a result of the regional water balance caused mainly by interaction of two factors: (i) fluctuations of water inflow to the Lake, (ii) water exploitation in the adjacent aquifers and consumptions from the lake (pumping, diversion, etc). The replenishment of the lake occurs through drainage from surrounding mountains (Galilee, Golan Heights), entering the lake through the Jordan River and secondary streams (85%), direct precipitation (11%), fresh-saline springs discharging along the shoreline, divertion from Yarmouk river and internal springs and seeps. The major losses occur through the National Water Carrier (ca. 44%), evaporation (38%), local consumption and compensation to Jordan (in sum 12%). In spite of the increasing role of water exploitation, the natural inflow to the Lake remains the dominant factor of hydrological regime of the Tiberias Lake. Additionally, series of natural yield to the LT are reconstructed with precipitation data measured in the Tiberias basin (1922-2012). The earlier period (1877-1921) is evaluated considering long rainfall records at Beirut and Nazareth stations (Middle East Region). This data enables to use the LT yield as a complex indicator of the regional climate change. Though the data applies to the LT, this example shows the importance of large database. Their compilation defines the correct set-up of joint methodologies such as numerical modeling and hydrochemical analyses aimed to understand large-scale hydrological processes.

    BACKGROUND: Proper management of patients with Kallmann syndrome (KS) allows them to attain a normal reproductive health. The purpose of this study is to demonstrate the presentation modalities, phenotypes and the modes of inheritance among 32 patients with Kallmann syndrome in Jordan. Recognition of the syndrome allows for prompt proper management and provision of genetic counselling. SUBJECTS: Over a period of five years (1999-2004), the clinical and inheritance profiles of 26 male and 6 female patients with Kallmann syndrome from 12 families were evaluated at the National Center for Diabetes, Endocrinology and Genetics in Jordan. RESULTS: The patients belonged to twelve Jordanian and Palestinian families and their age at presentation ranged from 4 - 46 years. Nine boys aged 4-14 years presented with cryptorchidism and microphallus, all other males presented with delayed puberty, hypogonadism and/or infertility. The main presentation among six female patients was primary amenorrhea. Intrafamilial variability in clinical phenotype was specifically evident for renal abnormalities and sensorineural hearing impairment. Familial KS was diagnosed in 27 patients belonging to five families with the X-linked mode of inheritance and two families with the autosomal recessive mode of inheritance. CONCLUSIONS: (1) the majority of cases in this study represented the X-linked form of KS, which might point to a high prevalence of Kal 1 gene in the population. (2) Genetic counselling helps these families to reach a diagnosis at an early age and to decide about their reproductive options. (3) Children presenting with cryptorchidism and microphallus in our population should be investigated for KS. PMID:15500697

    Phenotypic diversity of five Jordanian populations of cyst nematodes, Heterodera spp. collected from five regions from Jordan (Ar-Ramtha, Madaba, Dana, Al-Karak, and Jerash) was investigated. Soil samples were collected from one representative field in each region. Morphological and morphometrical characteristics revealed that Heterodera latipons is dominated in cereal fields at Ar-Ramtha, Madaba, Dana and Al-Karak regions and Heterodera schachtii in Jerash. Cysts populations from all cereal fields had bifenestrate vulval cone and a strong underbridge. Wherever, cysts of the cabbage population had ambifenestrate vulval cone with long vulval slit. The bullae were absent in Ar-Ramtha, Madaba and Dana populations, but present in Al-Karak and Jerash. Based on 12 morphometrical characters, the first three functions in canonical discriminant analysis accounted 99.3% of the total variation. Distance from dorsal gland duct opening to stylet base, underbridge length, a = L/W (body length/midbody width) and length of hyaline tail tip had strong and significant contributions in the first function. While the second function was strongly influenced by length of hyaline tail, fenestral length, fenestral width and tail length. However, the third canonical discriminate function was found to be influenced by stylet length, fenestral length, a = L/W (body length/midbody width) and underbridge width. The graphical representation of the distribution of the samples showed that the first canonical discriminant function clearly separated H. schachtii from Jerash from other populations. Whereas, H. latipons collected from Madaba and Dana were clearly separated in the second function. The results indicated that differences at morphological and morphometrical levels revealed diverse populations of Heterodera spp. in Jordan. PMID:26858546

    Pascual Jordan's path-breaking role as the protagonist of quantum field theory (QFT) is recalled and his friendly dispute with Dirac's particle-based relativistic quantum theory is presented as the start of the field-particle conundrum which, though in modified form, persists up to this date. Jordan had an intuitive understanding that the existence of a causal propagation with finite propagation speed in a quantum theory led to radically different physical phenomena than those of QM. The conceptional-mathematical understanding for such an approach began to emerge only 30 years later. The strongest link between Jordan's view of QFT and modern "local quantum physics" is the central role of causal locality as the defining principle of QFT as opposed to the Born localization in QM. The issue of causal localization is also the arena where misunderstandings led to a serious derailment of large part of particle theory e.g. the misinterpretation of an infinite component pointlike field resulting from the quantization of the Nambu-Goto Lagrangian as a spacetime quantum string. The new concept of modular localization, which replaces Jordan's causal locality, is especially important to overcome the imperfections of gauge theories for which Jordan was the first to note nonlocal aspects of physical (not Lagrangian) charged fields. Two interesting subjects in which Jordan was far ahead of his contemporaries will be presented in two separate sections. Dedicated to my teacher and role model: Rudolf Haag.

    The Jordan River, flowing from the Mount Hermon area to the Dead Sea, is an important freshwater source in the region. Its water is almost fully used by withdrawal from Lake Kinneret, fed to a large extent from the upper Jordan River (UJR) basin. Future climate change is expected to increase the pressure on the water availability in a region already now suffering from scarcity of water. Simulation of the future UJR discharge is therefore a societal highly relevant key scientific task. The contribution presents simulations of the future discharge of the Upper Jordan River based on climate change data from five different RCM models run in two Coordinated Regional Climate Downscaling Experiments (CORDEX) experiments. This data are applied together with the hydrological simulation model WaSiM-ETH. Obtained findings extend the previous simulations performed within the GLOWA Jordan River project (www.glowa-jordan-river.de), an interdisciplinary research project providing scientific support for sustainable water management in the Jordan River region. The presentation discuses the difficult constraints of hydrological simulations in the UJR region, which include complex terrain, karstic features and missing observational meteorological reference. It describes the setup of the applied hydrological model and concentrates upon the obtained results. The performed simulations for the period from 1976 to 2100 indicate an increasing annual mean temperature for 20071-2100 by 2.6 K above the 1971-2000 mean. The simulated ensemble mean precipitation is predicted to decrease in this period by 20 %. Related to the mean for 1976 - 2000, the discharge of the upper Jordan River is simulated to decrease by 25.3% until 2100

  16. The geochemistry of groundwater resources in the Jordan Valley: The impact of the Rift Valley brines

    The chemical composition of groundwater in the Jordan Valley, along the section between the Sea of Galilee and the Dead Sea, is investigated in order to evaluate the origin of the groundwater resources and, in particular, to elucidate the role of deep brines on the chemical composition of the regional groundwater resources in the Jordan Valley. Samples were collected from shallow groundwater in research boreholes on two sites in the northern and southern parts of the Jordan Valley, adjacent to the Jordan River. Data is also compiled from previous published studies. Geochemical data (e.g., Br/Cl, Na/Cl and SO4/Cl ratios) and B, O, Sr and S isotopic compositions are used to define groundwater groups, to map their distribution in the Jordan valley, and to evaluate their origin. The combined geochemical tools enabled the delineation of three major sources of solutes that differentially affect the quality of groundwater in the Jordan Valley: (1) flow and mixing with hypersaline brines with high Br/Cl (>2 ?? 10-3) and low Na/Cl (<0.8) ratios; (2) dissolution of highly soluble salts (e.g., halite, gypsum) in the host sediments resulting in typically lower Br/Cl signal (<2 ?? 10-3); and (3) recharge of anthropogenic effluents, primarily derived from evaporated agricultural return flow that has interacted (e.g., base-exchange reactions) with the overlying soil. It is shown that shallow saline groundwaters influenced by brine mixing exhibit a north-south variation in their Br/Cl and Na/Cl ratios. This chemical trend was observed also in hypersaline brines in the Jordan valley, which suggests a local mixing process between the water bodies. ?? 2007 Elsevier Ltd. All rights reserved.

  18. Urbanisation of Suweimeh area, Jordan, versus sinkholes and landslides proliferation

    The Dead Sea is a terminal lake whose level lowers each year of about one meter per year since more than one decade. This is caused mainly by the diversion of surface waters from its watershed. Currently, 1/10 of the Jordan River still reaches the salt lake. The rapid lowering of the lake level does not allow all the surrounding groundwater tables to adjust their level to that of the Dead Sea. This imbalance causes an always faster migration of a part of the groundwater causing underground erosion leading to the formation of sinkholes along the coast, especially where discontinuities, such as faults, are present. The first collapses occurred in the years 1980-90. From the 2000s, in Jordan, they have proliferated to the point of causing serious damages to the facilities of the Arab Potash Company, the agricultural area of Ghor Al Haditha, and more recently the touristic region of Suweimeh. Aware of the problem and the need for gradual rising of the lake level, the Jordanian authorities attended from 2009 to 2011 to the feasibility study of the Red Sea - Dead Sea conduit. Currently, on the one hand, the growing environmental imbalance, and, on the other hand, the desires to develop economic activities along the coast, imply that more goods will be exposed to damages. For example, the area of Wadi Mujib Bridge was rebuilt completely in the late 2000s. It is the same for the 12 km of the dam 18 of an evaporation pond Arab Potash Company. The Numeira Salt Factory was completely destroyed in Ghor Al Haditha and was relocated to Safi. In August 2012, during touristic period, a landslide destroyed half of the Holiday Inn front beach, Suweimeh area ... End of December 2012, a team lead by Prof. Najib Abou Karaki warned the Arab Potash Company of the presence of a circular depression 250 m in diameter within the evaporation pond SP-0A. Although the dike of this saltpan is closely monitored, the exact location and shape of this large sinkhole were not known to the security managers. The frequency and intensity of the damages increase each year and therefore new hazards are expected during this decade.

  19. The Mediterranean Oscillation and precipitation in the Jordan River region

    NASA Astrophysics Data System (ADS)

    2014-05-01

    Most of the precipitation in the Eastern Mediterranean (EM) is associated with mid-latitude cyclones (Black, 2011). Furthermore, a low pressure over this region is often accompanied by a high pressure in the Western Mediterranean (WM). This pattern has been referred to as the Mediterranean Oscillation and given rise to the Mediterranean Oscillation Index (MOI), which can be expressed as pressure differences between Algiers in the WM and Cairo in the EM (Palutikof et al., 1996). In this study, the relationship between the MOI and precipitation in the Jordan River region, located in the EM is addressed. First of all, 30 precipitation series were tested for homogeneity and serial correlation. Thereafter, Empirical Orthogonal Function (EOF) analyses were applied to the homogenous series and the years 1960-1993. The results showed that the EOF-1 explained 60-71% of the precipitation variance and received a significant correlation with the MOI in December-February whereas no correlation was obtained for the EOF-2. In order to obtain the large scale pressure anomalies associated with winter precipitation in the study region, the EOF-1 coefficient time series was correlated with Sea Level Pressure (SLP) obtained for ca. 23° W to 70° E and 5° N to 67° N. This resulted in a correlation coefficient between -0.5 and 0.5; where negative values correspond to below normal SLP, and positive values to above normal SLP by the time of rainfall in the study region. The spatial pattern showed above normal SLP over central Europe and the WM and below normal SLP in the EM. Hence, it was reminiscent of the Mediterranean Oscillation and consistence with the results from the previous correlation analysis. The probability of precipitation during negative and positive MOI phases was thereafter derived by fitting gamma distributions to monthly precipitation. The result showed that negative MOI phases are associated with low- and below normal winter precipitation whereas positive MOI phases are associated with high- and above normal winter precipitation. As an example; during negative MOI phases the probability of below average precipitation is 78%. During positive MOI phases the probability is 41%. These findings can be considered valuable for the purpose of forecasting drought within the Jordan River region. References: Black, E. (2011).

  20. Carbon Dioxide Emissions from Reservoirs in the Lower Jordan Watershed.

    2015-01-01

    We have analyzed monthly hydrological, meteorological and water quality data from three irrigation and drinking water reservoirs in the lower Jordan River basin and estimated the atmospheric emission rates of CO2. The data were collected between 2006 and 2013 and show that the reservoirs, which differ in size and age, were net sources of CO2. The estimated surface fluxes were comparable in magnitude to those reported for hydroelectric reservoirs in the tropical and sub-tropical zones. Highest emission rates were observed for a newly established reservoir, which was initially filled during the sampling period. In the two older reservoirs, CO2 partial pressures and fluxes were significantly decreasing during the observation period, which could be related to simultaneously occurring temporal trends in water residence time and chemical composition of the water. The results indicate a strong influence of water and reservoir management (e.g. water consumption) on CO2 emission rates, which is affected by the increasing anthropogenic pressure on the limited water resources in the study area. The low wind speed and relatively high pH favored chemical enhancement of the CO2 gas exchange at the reservoir surfaces, which caused on average a four-fold enhancement of the fluxes. A sensitivity analysis indicates that the uncertainty of the estimated fluxes is, besides pH, mainly affected by the poorly resolved wind speed and resulting uncertainty of the chemical enhancement factor.

    In this study, we completed the whole genome sequence of a new tobamovirus isolated from tomato plants grown in greenhouses in Jordan during the spring of 2015. The 6393-nt single-stranded RNA (ssRNA) genome encodes four proteins, as do other tobamoviruses: two replication-related proteins of 126 kDa and 183 kDa, a 30-kDa movement protein (MP) and a 17.5-kDa coat protein (CP). Phylogenetic analysis showed that this virus does not group with either the tomato mosaic virus (ToMV) or the tobacco mosaic virus (TMV) clades. Instead, it stems from a branch leading to the TMV clade. Analysis of possible recombination events between this virus and representative isolates of closely related tomato-infecting tobamoviruses showed that at least one region originated by recombination. We provide evidence that we have identified a new tobamovirus, for which we propose the name "tomato brown rugose fruit virus". PMID:26586328

    This study was carried out in the summer of 2005 and investigated all of active public swimming pools (85 out of 93) in Amman, the capital of Jordan. The aim of this study was to find out if these swimming pools are in compliance with Jordanian Standards for Swimming Pools Water (JS 1562/2004). The pools were surveyed against the water microbial quality and other physicochemical parameters indicated in the standards. Two samples from each pool were collected for microbial analysis and pools monitoring were carried out during the afternoon of the weekends when the pools are most heavily used. The results indicated overall poor compliance with the standards. Compliance of the pools water to the microbial parameters was 56.5%, for residual chlorine 49.4%, for pH 87.7%, water temperature 48.8%, and bathing load 70.6%. The results also indicated that water microbial quality deteriorated with time. Multivariate analysis showed significant association of water contamination with time of sample collection, residual chlorine, water temperature and load of swimmers. The poor compliance was attributed to lack of proper disinfection, staff training, proper maintenance, and timely inspection. PMID:19139533

    Necropsy of 340 stray and semi-stray dogs (Canis familiaris) and nine red foxes (Vulpes vulpes) from Jordan revealed that 239 dogs (70.3%) and all foxes were infected with at least one intestinal helminth species. No trematodes were found in the intestine of these hosts. The overall infection rates with cestodes, nematodes and acanthocephalans in dogs were 66.8%, 4.4% and 2.9%, respectively. The following cestodes were identified: Echinococcus granulosus (9.4%), Taenia pisiformis (11.8%), T. hydatigena (7.4%), T. ovis (4.4%), T. multiceps (3.8%), T. taeniaeformis (2.9%), Dipylidium caninum (19.4%), Joyeuxiella (3.2%), Diplopylidium (2.4%), and Mesocestoides (0.9%). Other intestinal worms in dogs were Toxascaris (2.6%), Toxocara canis (1.2%), and Protospirura (0.6%) nematodes, and gigantorhynchiid acanthocephalans (2.9%). Intestinal helminths found in foxes included cestodes (D. caninum, Joyeuxiella, Diplopylidium, Mesocestoides), nematodes (Protospirura, Uncinaria stenocephala and Oxynema) and an acanthocephalan (Macracanthorhynchus). In both hosts, most helminths were recovered from the second intestinal segment of four equally divided segments. PMID:10540955

    The present study examines attitudes towards honor crimes amongst a sample of 856 ninth grade students (mean age?=?14.6, SD?=?0.56) from 14 schools in Amman, Jordan. Descriptive findings suggest that about 40% of boys and 20% of girls believe that killing a daughter, sister, or wife who has dishonored the family can be justified. A number of theoretically meaningful predictors were examined: Findings suggest that attitudes in support of honor killings are more likely amongst adolescents who have collectivist and patriarchal world views, believe in the importance of female chastity amongst adolescents, and morally neutralize aggressive behavior in general. Findings for parental harsh discipline are mixed: While the father's harsh discipline is predictive of honor killing attitudes, the mother's behavior is not. Furthermore, support for honor killing is stronger amongst male adolescents and adolescents for low education backgrounds. After controlling for other factors religion and the intensity of religious beliefs are not associated with support for honor killings. Models were tested separately for male and female respondents and suggested no systematic differences in predictors. Limitations and implications are discussed. PMID:23744567

    The Jordan Valley Quadrangle, Oregon and Idaho, was evaluated to identify and delineate areas favorable for uranium deposits in accordance with criteria developed for the National Uranium Resource Evaluation. Surface radiometric reconnaissance and geochemical sampling were used for overall evaluation of the quadrangle. Detailed rock sampling, geologic mapping, and examination of uranium deposits and occurrences were performed in areas suspected to be favorable. The northeast part of the McDermitt caldera within the quadrangle is favorable for volcanogenic deposits associated with the ring-fracture zone. The favorable area contains the Aurora uranium deposit, the Bretz mercury mine, and the Cottonwood Creek occurrence. The Triangle Ranch area and the Snake River Plain, both in the northeast part of the quadrangle, have environments that may be favorable for uranium deposits in sandstone but are considered unevaluated due to lack of subsurface data and lack of detailed investigations. Rocks in the remainder of the quadrangle are considered unfavorable for uranium deposits because of low uranium contents, basic to intermediate compositions, or lack of favorable structures.

    Hypertension is the most common cardiovascular disease. No data exists on the health status of the largest ethnic groups in Jordan. Seven hundred ninety two Chechens and Circassians participated in this study. Two readings of systolic and diastolic blood pressure were taken from the left arm with the subject seated and the arm at heart level, after at least 5 min of rest, using standardized mercury sphygmomanometer. The mean of the two readings were taken as the individual's blood pressure. The overall prevalence rate of hypertension was 23.9%. Risk factors for hypertension were: family history (OR = 3.6, CI, 2.1, 6.3), female gender (OR = 2.5, CI, 1.7, 4.0), Dyslipidemia (OR = 2.3, CI, 1.5, 3.6), waist measurement above normal range (OR = 1.1, CI, 1.2-1.3) and older age (OR = 1.1, CI, 1.0-1.1). Public health efforts must be directed toward screening high risk individuals and intervening at early stage to improve health outcomes. PMID:21959712

    This study explored the relationship between intimate partner violence (IPV) and current contraception use among ever-married women in Jordan. Analysing a sample (n = 3434) from the 2007 Jordan demographic and health survey, women who reported ever experiencing severe physical violence from their husband were significantly less likely to use contraception than women who did not report severe physical violence (OR = 0.34). Conversely, women who reported ever experiencing sexual IPV were significantly more likely to use contraception (OR = 1.50). Emotional and less severe physical IPV were not significantly related to contraception use. Education, wealth, age, number of children, and fertility preferences were positively associated with contraception use, while residence in the Badia area and consanguineous marriages were negatively associated with contraception use. The findings have implications for the provision of IPV screening and contraception services in Jordan, as well as the specification of services for women most vulnerable to IPV. PMID:24313152

    The Iraq conflict resulted in the largest displacement in the Middle East since the Palestinian crisis, and provision of health services to the displaced population presents a critical challenge. The study aimed to provide information on chronic medical conditions and disability to inform humanitarian assistance planning. Nationally representative cross-sectional surveys of Iraqi populations displaced in Jordan and Syria were conducted in late 2008 and early 2009. Clusters of 10 household were randomly selected using probability-based sampling; a total of 1200 and 813 Iraqi households in Jordan and Syria, respectively, were interviewed. The majority of respondents in both countries perceived healthcare as unaffordable but accessible; cost was an important barrier to care. In Jordan, most routine health expenditures were for medications where in Syria, expenses were divided between medical consultations and medication. Chronic disease prevalence among adults was 51.5% (confidence interval (CI): 49.4-53.5) in Syria and 41.0% (CI: 39.4-42.7) in Jordan, most common were hypertension and musculoskeletal problems. Overall disability rates were 7.1% (CI: 6.3-8.0) in Syria and 3.4% (CI: 3.0-3.9) in Jordan. In both countries, the majority of disability was attributed to conflict, prevalence was higher in men than women, and depression was the leading cause of mental health disability. Chronic illnesses, disabilities and psychological health are key challenges for the Iraqi population and the health systems in Jordan and Syria. Continued attention to the development of systems to manage conditions that require secondary and tertiary care is essential, particularly given reported difficulties in accessing care and the anticipated prolonged displacement.

    Jordan canonical forms are used extensively in the literature on control systems. However, very few methods are available to compute them numerically. Most numerical methods compute a set of basis vectors in terms of which the given matrix is diagonalized when such a change of basis is possible. Here, a simple and efficient method is suggested for computing the Jordan canonical form and the corresponding transformation matrix. The method is based on the definition of a generalized eigenvector, and a natural extension of Gauss elimination techniques.

    Two main research questions are framing this investigation: (1) the main taxa of the medicinal importance value altered the Showbak forest stand and species composition? (2) The most safe species and what are the toxic ones (unsafe). These two research questions are the vital ones to draw a clear image about the wild medicinal plants of this investigated area of Showbak region in Jordan. 79 wild medicinal plant species were investigated in this study which are used in traditional medication for the treatment of various diseases. Most of the locals interviewed dealt with well-known safe medicinal plants such as Aaronsohnia factorovskyi Warb. et Eig., Achillea santolina L., Adiantum capillus-veneris L., Artemisia herba-alba L., Ceratonia siliqua L., Clematis recta L., Herniaria hirsuta L., Malva neglecta Wallr., Rosmarinus officinalis L., Ruta chalepensis L., Salvia triloba L., Sarcopoterium spinosa (L.) Spach., Thymbra capitata (L.) Hof, and Urginea maritima Barker. Many of the wild medicinal plants investigated were toxic and needed to be practiced by practitioners and herbalists rather than the local healers. These plants include Calotropis procera Willd R.Br., Citrullus colocynthis (L.) Sch., Datura stramonium L., Digitalis purpurea L., Ecballium elaterium (L.) A.Rich., Euphorbia helioscopia L., Euphorbia tinctoria Boiss., Glaucium corniculatum (L.) Curt., Hyoscyamus aureus L., Mandragora officinarum L., Nerium oleander L., Ricinus communis L., Solanum nigrum L., Withania somnifera (L.) Dunel. The conservation of medicinal plants and natural resources is becoming increasingly important, so this research is trying to collect information from local population concerning the use of medicinal plants in Showbak; identify the most important specie; determine the relative importance value of the species and calculate the informant consensus factor (ICF) for the medicinal plants. Obtaining results is relied on the interviewee's personal information and the medicinal use of specific plants. PMID:19429338

    In this study, a low background gamma-ray spectrometer based on a Hyper Pure Germanium detector was used to determine the activity concentrations of natural radionuclides in soil samples from various locations within the Ruseifa municipal landfill in Jordan. The chemical composition of the samples was also determined using a Wavelength Dispersive X-Ray Fluorescence Spectrometer. The maximum and minimum annual outdoor effective doses were found to be 103 and 36microSva(-1) in the old landfill and Abu-Sayaah village, respectively. The annual outdoor effective dose at the recent landfill site was found to be 91microSva(-1). The annual effective dose equivalents from outdoor terrestrial gamma radiation at the old landfill and the recent landfill were higher than the typical worldwide value of 70microSva(-1). Thus, some remediation of the soils on both old and recent landfills should be considered before any development for public activities. This could be achieved by mixing with clean soil from areas which are known to have lower radiation background. The concentration of heavy metals Zn, Cr, and Ba in the three sites included in this study were found to be higher than the background levels in the soil samples of the control area (Abu-Sayaah village). The enrichment factors for the above three elements were calculated and found to be: complex building site: Zn=2.52 and Ba=1.33; old landfill site: Cr=1.88, Zn=3.64, and Ba=1.26; and recent landfill site: Cr=1.57, Zn=2.19, and Ba=1.28. There was a strong negative correlation between the concentrations of the metallic elements (Mg, Al, Mn, Fe and Rb) and the concentrations of Zn, Ba, and Cr. Moreover, a strong positive correlation was found between Zn, Ba, and Cr. Thus these elements were enriched in the solid waste. PMID:18215446

    Early detection of emerging disease events is a priority focus area for cooperative bioengagement programs. Communication and coordination among national disease surveillance and response networks are essential for timely detection and control of a public health event. Although systematic information sharing between the human and animal health sectors can help stakeholders detect and respond to zoonotic diseases rapidly, resource constraints, and other barriers often prevent efficient cross-sector reporting. The purpose of this research project was to map the laboratory and surveillance networks currently in place for detecting and reporting priority zoonotic diseases in Jordan in order to identify the nodes of communication, coordination, and decision-making where health and veterinary sectors intersect, and to identify priorities and gaps that limit information sharing for action. We selected three zoonotic diseases as case studies: highly pathogenic avian influenza (HPAI) H5N1, rabies, and brucellosis. Through meetings with government agencies and health officials, and desk research, we mapped each system from the index case through response – including both surveillance and laboratory networks, highlighting both areas of strength and those that would benefit from capacity-building resources. Our major findings indicate informal communication exists across sectors; in the event of emergence of one of the priority zoonoses studied, there is effective coordination across the Ministry of Health and Ministry of Agriculture. However, routine formal coordination is lacking. Overall, there is a strong desire and commitment for multi-sectoral coordination in detection and response to zoonoses across public health and veterinary sectors. Our analysis indicates that the networks developed in response to HPAI can and should be leveraged to develop a comprehensive laboratory and surveillance One Health network. PMID:26528460

  17. Methane emissions from domestic waste management facilities in Jordan--applicability of IPCC methodology.

    PubMed

    Abdulla, F A; al-Ghazzawi, Z D

    2000-02-01

    In this paper, methane emissions from municipal wastewater treatment plants and municipal solid waste (MSW) landfills in Jordan for 1994 have been estimated using the methodology developed by the Intergovernmental Panel on Climate Change (IPCC). For this purpose, the 14 domestic wastewater treatment plants in the country were surveyed. Generation rates and characterization of MSW components as well as dumping and landfilling practices were surveyed in order to estimate 1994 CH4 emissions from these sites. Locally available waste statistics were used in cases where those of the IPCC guidelines were not representative of Jordan's statistics. Methane emissions from domestic wastewater in Jordan were estimated at 4.66 gigagrams (Gg). Total 1994 CH4 emissions from MSW management facilities in Jordan are estimated at 371.76 Gg--351.12 Gg (94.45%) from sanitary landfills, 19.83 Gg (5.33%) from MSW open dumps, and 0.81 Gg (0.22%) from raw sewage-water dumping ponds. Uncertainties associated with these estimations are presented. PMID:10680353

    1990-11-01

    This report addresses the oil shale-for-power-production option in Jordan. Under consideration are 20- and 50-MW demonstration units and a 400-MW, commercial-scale plant with, at the 400-MW scale, a mining operation capable of supplying 7.8 million tonnes per year of shale fuel and also capable of disposal of up to 6.1 million tonnes per year of wetted ash. The plant would be a direct combustion facility, burning crushed oil shale through use of circulating fluidized bed combustion technology. The report emphasizes four areas: (1) the need for power in Jordan, (2) environmental aspects of the proposed oil shale-for-power plant(s), (3) the engineering feasibility of using Jordan's oil shale in circulating fluidized bed combustion (CFBC) boiler, and (4) the economic feasibility of the proposed plant(s). A sensitivity study was conducted to determine the economic feasibility of the proposed plant(s) under different cost assumptions and revenue flows over the plant's lifetime. The sensitivity results are extended to include the major extra-firm benefits of the shale-for-power option: (1) foreign exchange savings from using domestic energy resources, (2) aggregate income effects of using Jordan's indigenous labor force, and (3) a higher level of energy security. 14 figs., 47 tabs.

  2. Linear maps preserving maximal deviation and the Jordan structure of quantum systems

    NASA Astrophysics Data System (ADS)

    Hamhalter, Jan

    2012-12-01

    In the algebraic approach to quantum theory, a quantum observable is given by an element of a Jordan algebra and a state of the system is modelled by a normalized positive functional on the underlying algebra. Maximal deviation of a quantum observable is the largest statistical deviation one can obtain in a particular state of the system. The main result of the paper shows that each linear bijective transformation between JBW algebras preserving maximal deviations is formed by a Jordan isomorphism or a minus Jordan isomorphism perturbed by a linear functional multiple of an identity. It shows that only one numerical statistical characteristic has the power to determine the Jordan algebraic structure completely. As a consequence, we obtain that only very special maps can preserve the diameter of the spectra of elements. Nonlinear maps preserving the pseudometric given by maximal deviation are also described. The results generalize hitherto known theorems on preservers of maximal deviation in the case of self-adjoint parts of von Neumann algebras proved by Molnár.

    2009-09-01

    SummaryAs a response to climate change, shifting rainfall trends including increased multi-year droughts and an escalation in extreme rainfall events are expected in the Middle East. The purpose of this study is to evaluate the potential impact of these shifting trends on stream flow in the Jordan River and its tributaries. We use a non-homogeneous hidden Markov model to generate artificial daily rainfall simulations which capture independently shifting trends of increased droughts and escalated extreme. These simulations are then used as input into a hydrological model calibrated for the upper catchments of the Jordan River to compare the impact on stream flow and water resources between the different rainfall scenarios. We compare the predicted baseflow and surface flow components of the tested watersheds, and find that while an increase in extreme rainfall events increases the intensity and frequency of surface flow, the over all flow to the Jordan River, and the characteristics of the baseflow in the Jordan River system is not largely impacted. In addition, though it has been suggested that in the case of a multi-year drought the karstic nature of the aquifer might lead to more intense, non-linear reductions in stream flow, here we quantify and show the conditions when annual stream flow reduce linearly with rainfall, and when these relations will become non-linear.

    With an explicit example, we show that Jordan frame and the conformally transformed Einstein frames clearly lead to different physics for a non-minimally coupled theory of gravity, namely Brans-Dicke theory, at least at the quantum level. The example taken up is the spatially flat Friedmann cosmology in Brans-Dicke theory.

    Concentrations of dissolved oxygen in the Jordan River in Salt Lake County decrease considerably as the river flows northward. Mean concentrations of dissolved oxygen decreased from 8.1 milligrams per liter at the Jordan Narrows to 4.7 milligrams per liter at 500 North Street during April 1981 to September 1982. Coincident with the decrease, the biochemical-oxygen demand increased from 5 to 7 milligrams per liter. About 50 percent of the dissolved-oxygen concentrations and 90 percent of the 5-day biochemical-oxygen demand measured downstream from 1700 South Street exceeded the State intended-use standards. An estimated 6. million pounds of oxygen-demanding substances as measured by 5-day biochemical-oxygen demand were discharged to the Jordan River during 1981 from point sources downstream from 9000 South Street. Seven wastewater-treatment plants contributed 77 percent of this load, nonstorm base flows contributed 22 percent, and storm flows less than 1 percent. The Surplus Canal diversion at 2100 South Street removed about 70 percent of this load, and travel time of about 1 day also decreased the actual effects of the load on the river. Reaeration rates during September and October were quite high (average K2 at 20 degrees Celsius was about 12 per day) between the Jordan Narrows and 9000 South Street, but they decreased to 2.4 per day in the reach from 1330 South to 1800 North Streets.

    Thrombosis is a major cause of morbidity and mortality worldwide. Genetic factors are one component of thrombosis. We studied the prevalence of two mutations that are known risk factors in the pathogenesis of arterial and venous thrombosis in the genetically isolated Circassian population in Jordan. Factor II G20210A and Factor V Leiden single nucleotide polymorphisms were analysed by polymerase chain reaction and restriction fragment length polymorphism method in 104 random unrelated subjects from the Circassian population in Jordan. The prevalence rates among the Circassian population in Jordan for Factor II G20210A was 12.2% and for Factor V Leiden was 7.7%. We have shown that the population is in Hardy-Weinberg equilibrium and that the prevalences of both mutations are within the range of other ethnic groups. This is the first study to describe Circassian health related genetic characteristics in Jordan. Such population-based studies will contribute to understanding the interaction between genetic and environmental risk factors. It will remain to be seen whether carriers of Factor II G20210A and Factor V Leiden are more likely to develop thrombosis. This issue should be studied in the future to determine the need for screening of these mutations particularly in thrombophilia patients. PMID:23011539

    Chebaane, Mohamed; El-Naser, Hazim; Fitch, Jim; Hijazi, Amal; Jabbarin, Amer

    Groundwater over-exploitation has been on the rise in Jordan. Competing demands have grown in the face of perennial water shortages, a situation which has been exacerbated by drought conditions in the past decade. This paper reports findings of a project in which management options to address over-exploitation were developed for one of Jordan's principal aquifer systems, the Amman-Zarqa Basin. Options for addressing the situation were developed through a participatory approach that involved government officials and various public and private sector interest groups. Particular efforts were made to involve well irrigators, who are likely to be heavily impacted by the changes required to reduce groundwater pumping to a sustainable level. With information obtained from a rapid appraisal survey as well as from interviews with farmers, community groups, government officials, and technical experts, an extensive set of options was identified for evaluation. Based on integrated hydrogeologic, social, and economic analysis, five complementary management options were recommended for implementation. These included the establishment of an Irrigation Advisory Service, buying out farm wells, placing firm limits on well ion and irrigated crop areas, exchanging treated wastewater for groundwater, and measures to increase the efficiency of municipal and industrial water use. Various combinations and levels of these options were grouped in scenarios, representing possible implementation strategies. The scenarios were designed to assist decision makers, well owners and other stakeholders in moving gradually towards a sustainable ion regime. Social and economic aspects of each option and scenario were analyzed and presented to stakeholders, together with a of legal, institutional and environmental ramifications. Combining scientific analysis with a participatory approach in the Amman Zarqa Basin groundwater management was devised as a prototype to be used in the management of other groundwater basins in Jordan. This participatory management approach would also be useful in other parts of the world that are experiencing similar groundwater over-exploitation problems. La surexploitation des eaux souterraines prend de l'importance en Jordanie. Les demandes en concurrence ont augmenté face à des déficits permanents d'eau, situation qui a été exacerbée par la sécheresse de la dernière décennie. Cet article rend compte de l'aboutissement d'un projet dans lequel des options de gestion portant sur la surexploitation ont été développées pour l'un des principaux systèmes aquifères de Jordanie, le bassin d'Amman Zarqa. Des options pour aborder cette situation ont été développées grâce à une approche participative qui implique des fonctionnaires du gouvernement et des groupes d'intérêts variés des secteurs public et privé. Des efforts particuliers ont été faits pour impliquer les irrigants utilisant des puits, qui sont probablement ceux qui ont le plus fort impact sur les changements attendus permettant de remettre le système en équilibre. À partir des informations obtenues de campagnes rapides d'évaluation, telles que des réunions de communautés et des entrevues avec des experts techniques du gouvernement, un large jeu d'options a été identifié pour l'évaluation. Basées sur une analyse hydrogéologique, sociale et économique, cinq options complémentaires de gestion ont été recommandées pour la réalisation. Ce sont la création d'un Service Consultatif d'Irrigation, achetant les puits agricoles, fixant des limites fermes aux prélèvements des puits et aux zones irriguées, échangeant les eaux usées traitées avec des eaux souterraines, et la mise en place de mesures pour accroître l'efficacité des usages collectifs et industriels. Des combinaisons et des niveaux variés de ces options ont été regroupés en scénarios, présentant les stratégies possibles de mise en œuvre. Les scénarios ont été mis au point pour assister les décideurs, les propriétaires de puits et les autres acteurs pour atteindre progressivement un régime de prélèvement durable. Les aspects sociaux et économiques de chaque option et de chaque scénario ont été analysés et présentés aux acteurs, en même temps qu'un résumé des ramifications légales, institutionnelles et environnementales. En combinant une analyse scientifique à une approche participative du bassin d'Amman Zarqa, la gestion des eaux souterraines a été imaginée comme un prototype pouvant être utilisé pour la gestion d'autres bassins aquifères de Jordanie. Il peut également être utile à d'autres régions du monde qui sont concernées par des problèmes similaires de surexploitation des eaux souterraines. La sobreexplotación de las aguas subterráneas ha ido en aumento en Jordania, donde las demandas en competición han crecido frente a una escasez perenne de agua, situación que ha sido agravada por el estado de sequía de la última década. Este artículo presenta los hallazgos de un proyecto en el que se han desarrollado opciones de gestión para hacer frente a la sobreexplotación en uno de los principales sistemas acuíferos de Jordania: la cuenca de Ammán-Zarga. Se ha elaborado opciones para afrontar la situación mediante un enfoque participativo que incluye a personal del gobierno y a diversos grupos de interés de los sectores público y privado. En particular, se ha intentado involucrar a los regantes que se sirven de aguas subterráneas, quienes tienen más probabilidad de ser directamente afectados por los cambios requeridos para devolver el sistema a un balance equilibrado. A partir de la información obtenida en rápidas campañas de valoración, así como de encuentros con la comunidad y entrevistas con los expertos técnicos del gobierno, se ha identificado un amplio conjunto de opciones para su evaluación. Basándose en un análisis integrado de los aspectos hidrogeológicos, sociales y económicos, se ha recomendado la implementación de cinco opciones complementarias de gestión: establecimiento de un Servicio Asesor de Riego; adquisición de pozos de granjas; imposición de límites estrictos en las extracciones de pozos y superficies de riego; substitución de las aguas subterráneas con aguas residuales depuradas; y medidas para incrementar la eficiencia de los usos municipales e industriales del agua. Se ha agrupado varias combinaciones y niveles de dichas opciones en escenarios, representando estrategias posibles de implementación. Los escenarios han sido diseñados para ayudar a los gestores en la toma de decisiones, a los propietarios de pozos y a otros agentes para que se vaya consiguiendo de forma gradual un régimen de extracciones sustentable. Se ha analizado los aspectos sociales y económicos de cada opción y de cada escenario, presentándolos a los diversos agentes, además de generar un resumen de ramificaciones legales, institucionales y medioambientales. Se ha concebido la combinación de un análisis científico con un enfoque participativo en la cuenca de Ammán-Zarga como un prototipo de gestión de las aguas subterráneas que puede ser aplicado a la gestión de otras cuencas en Jordania. También sería útil en otros lugares del mundo que estén experimentando problemas similares de sobreexplotación de los recursos hídricos subterráneos.

  10. Graduates in the kitchen. Educating girls: Jordan, Morocco and Syria.

    Muslim girls in Jordan have become better educated due to 3 decades of free and compulsory (10 years) schooling policy. Fertility has declined from 7.7 during 1971-75 to 5.6 during 1987-90. 58% of Jordanian women use some form of family planning (FP). Over 90% of eligible children are enrolled in school and 60% go on for advanced 2-year vocational or specialized training. There are actually more girls than boys in school. Although female literacy is high, only 14% are engaged in the labor force. A leader from the Business and Professional Women's Club related that man is considered the breadwinner. Some professions are considered unsuitable for women's employment. Traveling after dark alone is considered problematic for a decent woman. A visit to a school revealed that girls envisioned receiving training and working until marriage, having children, and looking after grandchildren. Many thought 3-4 children was an appropriate family size. Government statistics show that men enroll primarily in the industrial training courses and agriculture, while women tended toward more manual vocations such as sewing, knitting, cooking, hair styling, and secretarial skills. Out of the entire class there were only 2 or 3 girls who envisioned working after having children. Husbands were assumed to always work; if unemployment occurred, the girls thought that a factory job might be a possibility. Conversations with several women in the engineering school were conducted in a lecture hall rather than the cafeteria so the boys would not think they were making themselves available to them. Concern was also expressed about working with men, but the issue of unwanted approaches was dismissed during work hours because of their academic qualifications. Only if one worked lake in the day would there be anticipation of problems. There were many styles of dress for women ranging from modern Western garb to traditional attire in grey and black with a slit for the eyes. The most traditional woman expressed that she saw no difficulty in becoming a structural engineer because her personality would triumph. PMID:12318177

    2014-12-01

    Antone (Tony) Tarazi (1927-1999) was the first Palestinian neurosurgeon and the first neurosurgeon in Jordan. In 1952, Tarazi received his medical degree from the American University of Beirut in Lebanon. After completing neurosurgery training at the Montreal Neurological Institute in 1960, he returned to Palestine to practice neurosurgery in both Palestine and Jordan. For almost 10 years, he alone carried the load of neurosurgery for a population of >3 million people. His skills and knowledge enabled him to achieve admirable results with limited available resources. Tarazi was the president of the Palestinian Neurosurgical Society, a member of Jordan medical societies, and a member of the American Association of Neurological Surgeons. His continuous efforts to improve medical services extended beyond neurosurgery to many other fields. This article recounts Antone Tarazi's achievements and contributions to neurosurgery in Palestine and Jordan. PMID:25263256

  14. Energy demand in Jordan: a case study of energy-economy linkages

    A case study based on Jordan illustrates the application of existing methods of economy-wide modeling to the analysis of energy-economy interactions for a country with nearly total dependence on imported oil. The model focuses on the links between medium-term growth and energy prices, broad investment allocation decisions, and consistent energy demand projections. Key policy variables are domestic energy prices and subsidies, sectoral investment allocations, and foreign borrowing. The results indicate that energy demand is likely to increase as much as 25% faster than gross domestic product. The model shows that the effect of energy subsidies on demand growth are substantial, and that Jordan would be worse off with constant world prices and continued subsidies than with higher prices and no subsidies. 6 references, 7 tables.

    Internet addiction is a growing phenomenon affecting people in varying ways around the globe. This study examined the factor structure and internal reliability of the Internet Addiction Test (IAT) with a heterogeneous sample of university students in Jordan. The study used a cross-sectional design, and all the questionnaires were completed in classrooms. A sample of 587 students from seven universities in Jordan was obtained. The exploratory and confirmatory factor analyses of the 20-item IAT revealed that a four-factor solution offered the most parsimonious explanation of the data. The IAT reliably assesses distinct domains of Internet addiction. These domains are Excessive Use, Loss/Suffer, Attached To, and Impaired Social Relations. Thus, it is recommended to use the obtained four factors when assessing Internet addiction among a similar population. PMID:26440876

    We assessed the economic impact of Joint Commission International hospital accreditation on 5 structural and outcome hospital performance measures in Jordan. We conducted a 4-year retrospective study comparing 2 private accredited acute general hospitals with matched non-accredited hospitals, using difference-in-differences and adjusted covariance analyses to test the impact and value of accreditation on hospital performance measures. Of the 5 selected measures, 3 showed statistically significant effects (all improvements) associated with accreditation: reduction in return to intensive care unit (ICU) within 24 hours of ICU discharge; reduction in staff turnover; and completeness of medical records. The net impact of accreditation was a 1.2 percentage point reduction in patients who returned to the ICU, 12.8% reduction in annual staff turnover and 20.0% improvement in the completeness of medical records. Pooling both hospitals over 3 years, these improvements translated into total savings of US$ 593 000 in Jordan's health-care system. PMID:25876820

    The chemical and isotopic (87Sr/86Sr, ??11B, ??34Ssulfate, ??18Owater, ??15Nnitrate) compositions of water from the Lower Jordan River and its major tributaries between the Sea of Galilee and the Dead Sea were determined in order to reveal the origin of the salinity of the Jordan River. We identified three separate hydrological zones along the flow of the river: (1) A northern section (20 km downstream of its source) where the base flow composed of diverted saline and wastewaters is modified due to discharge of shallow sulfate-rich groundwater, characterized by low 87Sr/86Sr (0.7072), ??34Ssulfate (-2???), high ??11B (???36???), ??15Nnitrate (???15???) and high ??18Owater (-2 to-3???) values. The shallow groundwater is derived from agricultural drainage water mixed with natural saline groundwater and discharges to both the Jordan and Yarmouk rivers. The contribution of the groundwater component in the Jordan River flow, deduced from mixing relationships of solutes and strontium isotopes, varies from 20 to 50% of the total flow. (2) A central zone (20-50 km downstream from its source) where salt variations are minimal and the rise of 87Sr/86Sr and SO4/Cl ratios reflects predominance of eastern surface water flows. (3) A southern section (50-100 km downstream of its source) where the total dissolved solids of the Jordan River increase, particularly during the spring (70-80 km) and summer (80-100 km) to values as high as 11.1 g/L. Variations in the chemical and isotopic compositions of river water along the southern section suggest that the Zarqa River (87Sr/86Sr???0.70865; ??11B???25???) has a negligible affect on the Jordan River. Instead, the river quality is influenced primarily by groundwater discharge composed of sulfate-rich saline groundwater (Cl-=31-180 mM; SO4/Cl???0.2-0.5; Br/Cl???2-3??10-3; 87Sr/86Sr???0.70805; ??11B???30???; ??15Nnitrate ???17???, ??34Ssulfate=4-10???), and Ca-chloride Rift valley brines (Cl-=846-1500 mM; Br/Cl???6-8??10-3; 87Sr/86Sr???0.7080; ??11B???40???; ??34Ssulfate=4-10???). Mixing calculations indicate that the groundwater discharged to the river is composed of varying proportions of brines and sulfate-rich saline groundwater. Solute mass balance calculations point to a ???10% contribution of saline groundwater (Cl-=282 to 564 mM) to the river. A high nitrate level (up to 2.5 mM) in the groundwater suggests that drainage of wastewater derived irrigation water is an important source for the groundwater. This irrigation water appears to leach Pleistocene sediments of the Jordan Valley resulting in elevated sulfate contents and altered strontium and boron isotopic compositions of the groundwater that in turn impacts the water quality of the lower Jordan River. ?? 2004 Elsevier Ltd.

  19. Evidence for Jericho earthquakes from slumped sediments of the Jordan River delta in the Dead Sea

    NASA Astrophysics Data System (ADS)

    Niemi, Tina M.; Ben-Avraham, Zvi

    1994-05-01

    Seismic-reflection data and historical accounts suggest that a large submarine slump in the Dead Sea was produced by the most recent large earthquake along the Dead Sea-Jordan transform plate boundary, the ML 6.25 Jericho earthquake of July 11, 1927. The correlation supports the use of seismically triggered slump, landslide, and other sediment failures in lakes to infer the timing of paleoearthquakes. Furthermore, the location of the submarine slump adds to evidence that the 1927 earthquake was caused by rupture on a fault segment beneath the north basin of the Dead Sea. This fault rupture implies that the strain accumulation on the Jordan fault north of the Dead Sea is higher than previously recognized. Older seismically triggered slumps buried beneath the 1927 slump show that a record of ancient Jericho earthquakes can also be found in the sedimentary record. The estimated number and age range of these slumps suggest a long average earthquake recurrence time.

    Methylenetetrahydrofolate reductase (MTHFR) C677T single nucleotide polymorphism is a major inherited risk factor of venous thromboembolism. We sought to determine its prevalence in genetically isolated populations of Chechens and Circassians in Jordan. The MTHFR C677T mutation was analyzed from blood samples taken from 120 random unrelated Chechens and 72 Circassians. The prevalence of the MTHFR mutation in the Chechen population was 27.5% (allele frequency 15%); the prevalence among the Circassians was 50% (allele frequency 29.2%). The prevalence in the Chechen population is similar to that in Jordan and other world populations, but it is higher in the Circassian population. This study will contribute to understanding the interaction between genetic and environmental risk factors underlying thrombosis and will be useful in deciding which genetic variants should be tested in a clinical genetic testing service.

    We construct a relationship between integral and differential representation of second-order Jordan chains. Conditions to obtain regular potentials through the confluent supersymmetry algorithm when working with the differential representation are obtained using this relationship. Furthermore, it is used to find normalization constants of wave functions of quantum systems that feature energy-dependent potentials. Additionally, this relationship is used to express certain integrals involving functions that are solution of Schrödinger equations through derivatives.

    In the 6-year period from 1 August 1991 to 31 July 1997, at Queen Alia Military Hospital, Amman, Jordan, 1339 caesarean sections were performed out of a total 17,392 deliveries, representing an overall incidence of 7.7%. Indications for the caesarean sections were variable. Whether the operation was a primary or repeat procedure was often a major consideration. Efforts to prevent unnecessary caesarean sections should focus on reducing the frequency of first-time procedures. PMID:11370339

    We show that a state ? on a Jordan algebra 𝓐 induces complete inner product space if and only if ? is a convex combination of pure states. Inner product spaces generated by Type I n factor states and states on spin factors are described. We initiate study of completely positive maps in this connection by showing that pure completely positive map on a C ?-algebra gives always complete inner product space in the Stinespring construction.

    Hydrologic and hydraulic updates for Duck Creek and the lower part of Jordan Creek in Juneau, Alaska, included computation of new estimates of peak streamflow magnitudes and new water-surface profiles for the 10-, 50-, 100-, and 500-year floods. Computations for the 2-, 5-, 10-, 25-, 50-, 100-, 200-, and 500-year recurrence interval flood magnitudes for both streams used data from U.S. Geological Survey stream-gaging stations weighted with regional regression equations for southeast Alaska. The study area for the hydraulic model consisted of three channels: Duck Creek from Taku Boulevard near the stream's headwaters to Radcliffe Road near the end of the Juneau International Airport runway, an unnamed tributary to Duck Creek from Valley Boulevard to its confluence with Duck Creek, and Jordan Creek from a pedestrian bridge upstream from Egan Drive to Crest Street at Juneau International Airport. Field surveys throughout the study area provided channel geometry for 206 cross sections, and geometric and hydraulic characteristics for 29 culverts and 15 roadway, driveway, or pedestrian bridges. Hydraulic modeling consisted of application of the U.S. Army Corps of Engineers' Hydrologic Engineering Center River Analysis System (HEC-RAS) for steady-state flow at the selected recurrence intervals using an assumed high tide of 20 feet and roughness coefficients refined by calibration to measured water-surface elevations from a 2- to 5-year flood that occurred on November 21, 2005. Model simulation results identify inter-basin flow from Jordan Creek to the southeast at Egan Drive and from Duck Creek to Jordan Creek downstream from Egan Drive at selected recurrence intervals.

    There is scarcity in literature in regards to the exact levels of such compounds in the Middle Eastern region including Jordan. This study was conducted to measure the presence and levels of perfluoroalkyl substances (PFASs) (perfluoroocane sulfonate (PFOS) and perfluorooctanoic acid (PFOA)) in human milk and local fresh cow milk in northern Jordan and also to investigate the relationship between levels of PFASs and some sociodemographic characteristics of breastfeeding mothers and their infants as well as usage of Teflon kitchenware products. Seventy-nine milk samples were collected from breastfeeding women and 25 samples from local fresh cow milk in northern Jordan. Levels of PFOS and PFOA were liquid/liquid extracted (LLE) by acetone followed by purification on an Oasis hydrophilic-lipophilic balance (HLB) solid-phase extraction (SPE). Separations and detections were performed by liquid chromatography-tandem mass spectrometry. Limits of quantitation (LOQs) were 10 ng/L for both PFOA and PFOS. The measured concentrations ranged between non-detectable (ND) and 178 ng/L for PFOS and between 24 and 1120 ng/L for PFOA in human milk and between ND-178 ng/L and LOQ-160 ng/L in fresh cow milk, respectively. Median concentrations of PFOS in human milk samples from Jordan in this study were lower than those found in a recent study from Italy. Moreover, mean concentrations of PFOA and PFOS were significantly higher in milk samples provided by older women. Also, mean concentrations of PFOA was much higher in multiparas and those who have younger infants. The mean rank of PFOA was twice as high in the milk of women who had older Teflon products in kitchen compared to those who had relatively new Teflon products. PMID:25903175

    AIM: To study the epidemiology of gastric malignancies in Jordan as a model for Middle East countries where such data is scarce. METHODS: Pertinent epidemiological and clinicopathological data for 201 patients with gastric malignancy in north of Jordan between 1991 and 2001 were analyzed. RESULTS: Male: female ratio was 1.8:1. The mean age was 61.2 years, and 8.5% of the patients were younger than 40 years of age. The overall age- adjusted incidence was 5.82/100 000 population/year. The age specific incidence for males raised from 1.48 in those aged 30-39 years to 72.4 in those aged 70-79 years. Adenocarcinomas, gastric lymphomas, malignant stromal tumors, and carcinoids were found in 87.5%, 8%, 2.5%, and 2% respectively. There was an average of 10.1-month delay between the initial symptoms and the diagnosis. Only 82 patients underwent “curative” gastrectomy. Among adenocarcinoma groups, Lauren intestinal type was the commonest (72.2%) and the distal third was the most common localization (48.9%). The mean follow up for patients with gastric adenocarcinoma was 25.1 mo (range 1 mo -132 mo) . The 5-year survival rates for stages I (n = 15), II (n = 41), III (n = 59), and IV (n = 53) were 67.3%, 41.3%, 5.7%, and 0% respectively (P = 0.0001). The overall 5 year survival was 21.1%. CONCLUSION: Despite low incidence, some epidemiological features of gastric cancer in Jordan mimic those of high-risk areas. Patients are detected and treated after a relatively long delay. No justification in favor of a possible gastric cancer screening effort in Jordan is supported by our study; rather, the need of an earlier diagnosis and subsequent better care. PMID:15259060

    This study aimed to determine the seroprevalence and to identify risk factors associated with Neospora spp. infection in horses in Jordan. Management related data were collected from each farm and individual horses. Sera from 227 horses from 5 of 6 climatic regions in Jordan were analyzed for the presence of antibodies to Neospora spp. by ELISA kit. The study was performed during spring of 2010. The association between seropositivity and risk factors was analyzed. A total of 7 (3%) of 227 sera had antibodies for Neospora spp. There was a significant regional difference (P=0.018) between the 5 climatic regions. Positive cases were located in Amman and Irbid, while the other regions (Zarqa, Jordan Valley, and Wadi Mousa) had zero prevalence. The use of anthelmintics at least once a year resulted in a significant reduction of the seroprevalence to Neospora spp. (1.6% vs 9.8%). However, this might be a phenomenon by chance and a better hygiene since owners can invest in anthelmintics. Other risk factors such as age, gender, breed, usage, body condition score, grazing, presence of other animals mixed with the horses in the same property, and a history of previous diseases were not significantly associated with the seroprevalence to Neospora spp. infection. This is the first study to report on the presence of Neospora seropositive horses in Jordan. Further studies are warranted to better understand the role of certain risk factors in the transmission of Neospora spp. among horse population and to determine which Neospora spp. are responsible for the infection.

    A mandatory National Premarital Thalassemia Screening Program was implemented in Jordan in 2004. This cross-sectional study aimed to assess the knowledge and attitudes of university students in North Jordan toward this program. Data was collected from 542 students from four universities (two public and two private universities) located in North Jordan, using a structured questionnaire. Results of t-test and analysis of variance (ANOVA) showed that while respondents had adequate knowledge of and positive attitudes toward the premarital screening program, there was still a lack of knowledge about the disease itself. Nearly half the respondents were under the impression that β-thalassemia (β-thal) is a disease that can be treated simply. One-third of the respondents believed that if both partners were carriers of β-thal they should proceed with marriage. Negative attitude was revealed when many respondents believed that diagnosing a family member as a carrier affects other family members' future marriage opportunities. Significant associations were detected between the knowledge scores and gender, urban/rural residence, and the university where the students were enrolled. Students in private universities showed significantly lower attitude scores. Consideration of prenatal diagnostic services as part of a β-thal prevention program is necessary. It would also be helpful to include information about β-thal as a preventable inherited illness with a severe debilitating impact on the family in the high school curriculum. There is also a need for social marketing of the program. PMID:26821551

    Previous studies have identified a number of single nucleotide polymorphisms (SNPs) associated with type-2 diabetes (T2D), but copy number variation (CNV) association has rarely been addressed, especially in populations from Jordan. To investigate CNV associations for T2D in populations in Jordan, we conducted a CNV analysis based on intensity data from genome-wide SNP array, including 34 T2D cases and 110 healthy controls of Chechen ethnicity, as well as 34 T2D cases and 106 healthy controls of Circassian ethnicity. We found a CNV region in protein tyrosine phosphatase receptor type D (PTPRD) with significant association with T2D. PTPRD has been reported to be associated with T2D in genome-wide association studies (GWAS). We additionally identified 16 CNV regions associated with T2D which overlapped with gene exons. Of particular interest, a CNV region in the gene AKNA Domain Containing 1 (AKNAD1) surpassed the experiment-wide significance threshold. Endoplasmic reticulum (ER)-related pathways were significantly enriched among genes which are predicted to be functionally associated with human or mouse homologues of AKNAD1. This is the first CNV analysis of a complex disease in populations of Jordan. We identified and experimentally validated a significant CNVR in gene AKNAD1 associated with T2D. PMID:26292654

    This study estimated the seroprevalence and risk factors for acquiring Toxoplasma gondii infection by undergraduate female university students in Jordan. A cross-sectional study from September 2013 to July 2014 analysed 202 blood samples for IgG and IgM antibodies by enzyme-linked immunosorbent assay and a semi-constructed questionnaire was completed by participants to gather information about Toxoplasma infection risk factors. T. gondii IgG antibodies were detected in 66.5% of the females. Only one sample was positive for both IgG and IgM. Using ?2 test, six factors showed significant association with T. gondii infection (P ? 0.01). The multivariate logistic regression model showed that female students living in houses, wet areas, with income >US $750/month and using spring (untreated) water were 47.42, 10.20, 5.00, 3.25 more times at risk to be seropositive for T. gondii, respectively, compared to female students living in apartments, dry areas, with income ? US $750/month and using treated water, respectively. This study concluded that T. gondii infection in female university students in Jordan is high and most women become infected before marriage; however, congenital toxoplasmosis is still likely to occur in Jordan. Thus, dissemination of protective measures and knowledge by healthcare professionals is essential especially for pregnant women. PMID:25543692

    In September 1998, more than 800 young people in Jordan believed they had suffered from the side-effects of tetanus-diphtheria toxoid vaccine administered at school; 122 of them were admitted to hospital. For the vast majority, their symptoms did not result from the vaccine but arose from mass psychogenic illness. The role played by the media, the children's parents, and the medical profession in the escalation of this mass reaction appeared, at first sight, to be unusual and even unique to the circumstances in Jordan at the time. A review of the literature showed, however, that this mass reaction was similar in many ways to previous outbreaks, even though the underlying causes varied. There are about 200 published accounts of mass responses to situations involving suspected poisoning or other events. Because such mass reactions are relatively rare and the triggers so diverse, individuals faced with responding to them are unlikely to have prior experience in how to handle them and are unlikely to take bold steps to prevent their escalation. Indeed they may be unaware that such events have been recorded before. The lessons learned from this incident in Jordan may help other immunization programme managers to handle crisis situations elsewhere. PMID:11545334

    Jordan is one of the four water poorest countries in the world. It is a highly vulnerable arid region whose freshwater system is at a tipping point due to the confluence of severely limited water supplies, rapid population growth, refugee influxes, climate change and variability, internal and transboundary competition for shared freshwater resources, and institutional impediments. Our team is engaged in an interdisciplinary effort aimed at developing a new approach to evaluate policies that enhance sustainability of freshwater resource systems. Our work adopts a multi-agent modeling framework that incorporates institutional complexity to evaluate policy instruments for improving water security in Jordan. We are developing this model using a modular approach, integrating biophysical modules that simulate natural and engineered phenomena (e.g., groundwater-surface water flow, reservoir storage, network routing, salt balance, and crop yield) with human modules that represent behavior at multiple scales of decision making. The human modules adopt a multi-agent simulation approach, defining agents as autonomous decision-makers at the government, administrative, organizational, and user levels. Our goal is to construct a suite of policy intervention scenarios that will form the basis for analysis of freshwater sustainability. This work has benefitted from a strong working relationship with leaders of the water sector in Jordan. Our approach and the merit of the policy interventions should have significant transfer value to other water-stressed regions.

    This paper disentangles selected intertwined aspects of two great scientific developments: quantum mechanics and molecular biology. We look at the contributions of three physicists who in the 1930s were protagonists of the quantum revolution and explorers of the field of biology: Niels Bohr, Pascual Jordan, and Max Delbrück. Their common platform was the defense of the Copenhagen interpretation in physics and the adoption of the principle of complementarity as a way of looking at biology. Bohr addressed the problem of how far the results reached in physics might influence our views about life. Jordan and Delbrück were followers of Bohr's ideas in the context of quantum mechanics and also of his tendency to expand the implications of the Copenhagen interpretation to biology. We propose that Bohr's perspective on biology was related to his epistemological views, as Jordan's was to his political positions. Delbrück's propensity to migrate was related to his transformation into a key figure in the history of twentieth-century molecular biology.

    Two hundred and three groundwater samples were collected during March 2011 to June 2012 from the B2/A7 aquifer water supply wells of northern part of Jordan. The physicochemical properties were analyzed in situ for the major cations, anions, while certain heavy metals were analyzed in the laboratory. Some oilshale rock samples were geochemically analyzed. The Upper Cretaceous aquifer (B2/A7) is used as water supply for most of the communities in the study area. It consists of limestone, marly limestone, bedded chert, and minor phosphorite. Hydrochemical results from the B2/A7 aquifer indicate two main water types: alkaline-earth water (CaHCO3) and alkaline-earth water with high alkaline component (NaHCO3 (-), Na2SO4). Standard column leaching experiments on oilshale rock samples and the R-mode factor analysis suggest that the sources for elevated Mo concentrations in the groundwater of certain parts of northern Jordan are attributed to water-oilshale interaction, mobility of Mo down to the groundwater and the extensive use of fertilizers within these areas. Molybdenum (Mo) concentrations in the groundwater water range from 0.07 to 1.44 mg/L with an average value of 98 ?g/L. They are found to exceed the JISM and WHO guidelines in two areas in northern part of Jordan. Spatial distribution of Mo, using ordinary kriging techniques and the resulting map, shows high Mo concentration in the northwestern part near Wadi Al Arab area reaching concentrations of 650 ?g/L and in the southeastern corner of the investigated area, south of Al Ukaydir village, with an average concentration of 468 ?g/L. Both areas are characterized by extensive oilshale exposures with average concentration of 11.7 mg/kg Mo and intensive agricultural activities. These two areas represent approximately 33 % of the groundwater in the northern part of Jordan. Mobility of Mo to the groundwater in northern part of Jordan is attributed to two mechanisms. First, there is reductive dissolution of Fe-oxide, which releases substantial adsorbed Mo concentrations. Secondly, there is oxidation of Mo into dissolved forms in sulfide organic-rich system.

  17. Intermediate accelerated solutions as generic late-time attractors in a modified Jordan-Brans-Dicke theory

    2016-02-01

    In this paper we investigate the evolution of a Jordan-Brans-Dicke scalar field, Φ, with a power-law potential in the presence of a second scalar field, phi, with an exponential potential, in both the Jordan and the Einstein frames. We present the relation of our model with the induced gravity model with power-law potential and the integrability of this kind of models is discussed when the quintessence field phi is massless, and has a small velocity. The fact that for some fine-tuned values of the parameters we may get some integrable cosmological models, makes our choice of potentials very interesting. We prove that in Jordan-Brans-Dicke theory, the de Sitter solution is not a natural attractor. Instead, we show that the attractor in the Jordan frame corresponds to an ``intermediate accelerated'' solution of the form a(t) simeq eα1 tp1, as t → ∞ where α1 > 0 and 0 < p1 < 1, for a wide range of parameters. Furthermore, when we work in the Einstein frame we get that the attractor is also an ``intermediate accelerated'' solution of the form fraktur a(fraktur t) simeq eα2 fraktur tp2 as fraktur t → ∞ where α2 > 0 and 0Jordan frame. In the special case of a quadratic potential in the Jordan frame, or for a constant potential in the Einstein's frame, the above intermediate solutions are of saddle type. These results were proved using the center manifold theorem, which is not based on linear approximation. Finally, we present a specific elaboration of our extension of the induced gravity model in the Jordan frame, which corresponds to a particular choice of a linear potential of Φ. The dynamical system is then reduced to a two dimensional one, and the late-time attractor is linked with the exact solution found for the induced gravity model. In this example the ``intermediate accelerated'' solution does not exist, and the attractor solution has an asymptotic de Sitter-like evolution law for the scale factor. Apart from some fine-tuned examples such as the linear, and quadratic potential U(Φ) in the Jordan frame, it is true that ``intermediate accelerated'' solutions are generic late-time attractors in a modified Jordan-Brans-Dicke theory.

    A description placed in a historical context, of the physico-chemical investigations of DNA carried out in the period 1940-1950 by a group at University College, Nottingham led by J.M.Gulland and D.O.Jordan. The isolation of a pure sample of DNA from calf thymus was followed by its analysis by potentiometric titrations and by measurements at variable pH of viscosity and streaming birefringence. Unlike the phosphoric acid groups, the primary amino and enolic hydroxyl groups could only be titrated after prior treatment with strong acid or strong base. The conclusion of Gulland and Jordan, that extremes of pH caused liberation of amino and enolic hydoxyl groups by disruption of hydrogen bonds between neighbouring polynucleotide chains, proved to be of considerable importance. The article includes life histories of Gulland and Jordan, and reference to Linus Pauling's remarkable foresight during his Sir Jesse Boot Foundation Lecture delivered at Nottingham in 1948.

    Changes in groundwater levels and salinity in six groundwater basins in Jordan were characterized by using linear trends fit to well-monitoring data collected from 1960 to early 2011. On the basis of data for 117 wells, groundwater levels in the six basins were declining, on average about -1 meter per year (m/yr), in 2010. The highest average rate of decline, -1.9 m/yr, occurred in the Jordan Side Valleys basin, and on average no decline occurred in the Hammad basin. The highest rate of decline for an individual well was -9 m/yr. Aquifer saturated thickness, a measure of water storage, was forecast for year 2030 by using linear extrapolation of the groundwater-level trend in 2010. From 30 to 40 percent of the saturated thickness, on average, was forecast to be depleted by 2030. Five percent of the wells evaluated were forecast to have zero saturated thickness by 2030. Electrical conductivity was used as a surrogate for salinity (total dissolved solids). Salinity trends in groundwater were much more variable and less linear than groundwater-level trends. The long-term linear salinity trend at most of the 205 wells evaluated was not increasing, although salinity trends are increasing in some areas. The salinity in about 58 percent of the wells in the Amman-Zarqa basin was substantially increasing, and the salinity in Hammad basin showed a long-term increasing trend. Salinity increases were not always observed in areas with groundwater-level declines. The highest rates of salinity increase were observed in regional discharge areas near groundwater pumping centers.

    Background In Jordan, as in neighboring countries in the Middle East, higher education and higher employment rates in recent years among women have had an impact on traditionally based infant feeding. The objective of this study was to evaluate practice, knowledge and attitude to breastfeeding and to assess factors associated with breastfeeding among women in the north of Jordan. Methods A cross sectional study was carried out between 15 July 2003 and 15 August 2003. A total of 344 women with children aged between 6 months and 3 years from five different villages in the north of Jordan were randomly selected and interviewed. Information regarding participants' demographics, infant feeding in first six months of life, knowledge and attitude towards breastfeeding was collected. Results Full breastfeeding was reported by 58.3%, mixed feeding was reported by 30.3% and infant formula feeding was reported by 11.4%. Almost one third of the full breastfeeding group did so for 6–12 months, and almost two thirds did continue breastfeeding for more than one year. Employed women were more likely not to practice full breastfeeding compared to unemployed women (odds ratio 3.34, 95% CI 1.60, 6.98), and women who had caesarian delivery were more likely not to practice full breastfeeding compared to those who had vaginal delivery (odds ratio 2.36, 95% CI 1.17, 4.78). Jordanian women had a positive attitude but work place and short maternity leaves had a negative impact on breastfeeding. Conclusion This study showed that a high proportion of Jordanian women did breastfeed for more than one year. However, working women and those who deliver by caesarean section were less likely to breastfeed. It is speculated that adopting facilitatory measures at hospitals and work place could increase the rate of full breastfeeding. PMID:16995953

    The Dead Sea is a longitudinal (80 km {times} 20 km) terminal lake that was formed by the active Syrian-African transform fault. Considerably saline inflow from the Jordan River and a very high evaporation rate have led to the excessive salinity (360 g/L) and water density (1.226-1.232 g/cc) of the lake. The rate of evaporite precipitation is 630-2,000 mg/cm{sup 2}/yr. Clastic sediments from the Jordan River have formed a very moderately sloping (about 2{degree}) delta that covers the northern lake to a distance of 8 km offshore and to a depth of 300 m. Many irregularly shaped mounds of sediment that are acoustically transparent and that contain numerous discontinuous reflectors cover the delta slope. They extend over several hundred square meters each and rise 2-5 m above their surroundings. These sediments indicate active downslope slumping processes. The small-scale sedimentary pattern and the engineering properties of the sediments were examined by testing 6 core samples collected at various depths along the Jordan delta. Lengths range from 0.90 to 3.20 m. Depth of coring was restricted by an extremely hard, impenetrable layer of halite, and the topmost 10-25 cm consists of unconsolidated, recently deposited grainy halite. Euhedral crystals of halite are disseminated throughout the entire length of the core samples, especially in the deep-water cores. The high salinity of the pore water and the presence of large amounts of disseminated halite within the cores required modifications of the standard soil mechanics laboratory testing procedures. The sediments are predominantly dark brown, layered kaolinitic silty clays. They contain numerous conspicuous black organic-matter and sulfide-bearing layers and white aragonite and gypsum layers. Occasionally, slump structures are encountered.

    As a result of civil war, an estimated 2.8 million refugees have fled Syria and reside in neighboring countries, mainly Lebanon, Turkey, Jordan, and Iraq. The largest Syrian refugee camp in the region is Zaatari camp in Jordan, with approximately 79,000 refugees; another estimated 500,000 Syrian refugees live in Jordanian cities, towns, and villages, mostly in the capital (Amman) and in four northern governorates (Irbid, Mafraq, Jarash, and Zarqa). Although all registered refugees in Jordan receive food vouchers from the World Food Programme (WFP) and vulnerable refugees receive cash assistance from the United Nations High Commissioner for Refugees (UNHCR) and nongovernmental organizations, the nutritional status of some refugees might be compromised because of dislocation, lack of income, and limited access to nutritious foods. To assess the nutritional status of Syrian refugees, UNHCR, WFP, the United Nations Children's Fund (UNICEF), Medair International (a nongovernmental organization), and CDC, in collaboration with the United Nations Population Fund and the World Health Organization (WHO), conducted cross-sectional, population-representative cluster surveys in Zaatari camp and among refugees residing in the host community. The surveys were conducted during April-May 2014 with the principal objective of assessing nutritional status of refugee children aged 6-59 months and nonpregnant women of reproductive age (15-49 years). Preliminary findings indicated a high prevalence of anemia in Zaatari camp among both children and women (48.4% and 44.8%, respectively). Nutrition policies aimed at ensuring optimal child and maternal micronutrient status and addressing the underlying risk factors for anemia are likely to result in improved health outcomes and a reduction in anemia.

    Let ? : 𝔖(M1) ? 𝔖(M2) be a bijection (not assumed affine nor continuous) between the sets of normal states of two quantum systems, modelled on the self-adjoint parts of von Neumann algebras M1 and M2, respectively. This paper concerns with the situation when ? preserves (or partially preserves) one of the following three notions of "transition probability" on the normal state spaces: the transition probability PU introduced by Uhlmann [Rep. Math. Phys. 9, 273-279 (1976)], the transition probability PR introduced by Raggio [Lett. Math. Phys. 6, 233-236 (1982)], and an "asymmetric transition probability" P0 (as introduced in this article). It is shown that the two systems are isomorphic, i.e., M1 and M2 are Jordan ?-isomorphic, if ? preserves all pairs with zero Uhlmann (respectively, Raggio or asymmetric) transition probability, in the sense that for any normal states ? and ?, we have P (" separators=" ? ( ? ) , ? ( ? ) " separators=" ) = 0 if and only if P(?, ?) = 0, where P stands for PU (respectively, PR or P0). Furthermore, as an extension of Wigner's theorem, it is shown that there is a Jordan ?-isomorphism ? : M2 ? M1 satisfying ? = ??|𝔖(M1) if and only if ? preserves the "asymmetric transition probability." This is also equivalent to ? preserving the Raggio transition probability. Consequently, if ? preserves the Raggio transition probability, it will preserve the Uhlmann transition probability as well. As another application, the sets of normal states equipped with either the usual metric, the Bures metric or "the metric induced by the self-dual cone," are complete Jordan ?-invariants for the underlying von Neumann algebras.

    During field work in the Triassic of Jordan fossil wood remains have been discovered at five horizons (S-1AR-S-5AR) of the Late Triassic (Carnian) Abu Ruweis Formation in NW Jordan. In most horizons wood remains are too badly preserved to allow for a detailed xylotomic investigation. Only two horizons provided material which exhibited anatomical details: (1) in horizon S-1AR we found rare and rather small fragments of woody charcoal exhibiting cellular details (representing the first macroscopic evidence of paleo-wildfires from the Late Triassic of the Middle East), and (2) in horizon S-5AR surfaces of partly compressed (gagatized) and partly permineralized wood fragments exhibited anatomical details that could be investigated by means of scanning electron microscopy. All wood remains that allow for a detailed investigation show features typical of gymnosperms, but at the moment nothing can be said about a more specific taxonomic affinity of most of the woods, although wood from horizon S-5AR exhibits characteristics of protopinoid wood. Our data provide evidence that gymnospermous woody vegetation cover has existed in the source areas of the sediments deposited in the Abu Ruweis Formation in Jordan and that this woody vegetation occasionally experienced wildfires. This, together with lithological data, provides evidence for a seasonally dry (maybe even arid) climate during deposition of the Abu Ruweis Formation. On a larger scale our findings contribute to the very scarce current knowledge about Late Triassic wildfires on the entire continent Gondwana, from where so far only three records of macro-charcoals, as undisputed evidence of paleo-wildfires, have been published from this period.

    There is a need to recognize the difficulties experienced in managing waste and to understand the reasons for those difficulties, especially in developing countries such as Jordan. Zarqa is a Governorate located in central Jordan, which has 2874 registered industries, making up more than 52% of the total industries in the country. Zarqa Governorate suffers from serious solid waste problems. These problems arise from an absence of adequate policies, facilitating legislation, and an environmentally enthused public, which therefore have a negative impact on the environment and health. Solid waste generation in Zarqa Governorate has increased exponentially and has polluted natural resources and the environment. A significant change in municipal solid waste generation was evident between the years 1994 and 2000. The Zarqa Governorate generated 482 tons/day in 2002 with a per capita rate of 0.44 kg/cap-day [Consulting Engineers, 2002, Feasibility study for the treatment of industrial wastewater in Zarqa Governorate. A project funded by METAP and Zarqa Chamber of Industry. Unpublished report]. This manuscript assesses the current operational and management practices of solid waste in the Zarqa Governorate; and evaluates the associated issues of solid waste collection, storage, transport, disposal and recycling in developing countries. The lack of techniques, financial funds and awareness among public and private sectors form an obstacle for achieving a successful environmental program. Several options are proposed to address management goals. Although Jordan became the first country in the Middle East to adopt a national environmental strategy; waste disposal is still largely uncontrolled and large quantities of waste go uncollected. Ensuring proper management of solid wastes, enforcing regulations, and implementing proper environmental awareness programs that will enhance the public understanding and achieve greater efficiency, are the findings of this study.

    Water with high nitrate concentration (NO(3) (-)) is unfit for human consumption, especially when its concentration exceeded the threshold limit (50 mg/l) recommended by the health authorities such as the World Health Organization (WHO). In Jordan, there is a great concern for determination and monitoring organic and inorganic pollutants that may reach groundwater. Nitrate is highly mobile and present in domestic, agricultural and industrial waste in Jordan, and thus this study focused initially on nitrate as both a contaminant of concern and as an indicator of potential groundwater contamination. The present study determined the extent of nitrate contamination in groundwater in the study area and examined the likely sources of NO(3) (-). A total of 248 groundwater samples were collected from 16 wells in different sites of Al-Hashimiya area, Zerqa Governorate, Jordan, and investigated for NO(3) (-) concentrations. Moreover, measurements of temperature, electrical conductivity and pH were carried out in the field. Analysis was carried out according to the methods described by the American Public Health Association (APHA). Results showed that there was a dramatic increasing in NO(3) (-) concentrations from the year 2001 to 2006 for some selected wells in the present study. NO(3) (-) concentration in 2006 was ranged from 10 to 330 mg/l with an average of 77 mg/l. Overall, groundwater had elevated nitrate concentration with 92% of the samples containing more than 20 mg/l NO(3) (-), indicating the influence of human activities. This study has shown that there is a strong correlation between the nitrate concentration and the wastewater effluents as a source of pollution. PMID:17492487

    We report planktonic foraminiferal fluxes (accumulation rates) and oxygen isotopes (δ18O) from a nine-month sediment trap deployment, and δ18O from three sediment cores in Jordan Basin, Gulf of Maine. The sediment trap was deployed at 150 m, about halfway to the basin floor, and samples were collected every three weeks between August 2010 and May 2011. The planktonic foraminiferal fauna in the trap is dominated by Neogloboquadrina incompta that reached a maximum flux in the second half of October. Oxygen isotope ratios on that species indicate that on average during the collecting period it lived in the surface mixed layer, when compared to predicted values based on data from a nearby hydrographic buoy from the same period. New large diameter piston cores from Jordan Basin are 25 and 28 m long. Marine hemipelagic sediments are 25 m thick, and the sharp contact with underlying red deglacial sediments is bracketed by two radiocarbon dates on bivalves that indicate ice-free conditions began 16,900 calibrated years ago. Radiocarbon dating of foraminifera indicates that the basin floor sediments (270-290 m) accumulated at >3 m/kyr during the Holocene, whereas rates were about one tenth that on the basin slope (230 m). In principle, Jordan Basin sediments have the potential to provide time series with interannual resolution. Our results indicate the Holocene is marked by ~2°C variability in SST, and the coldest events of the 20th century, during the mid 1960s and mid 1920s, appear to be recorded in the uppermost 50 cm of the seafloor.

    Jordan has limited natural resources such as water and agricultural land. It is classified as an arid and semi arid country. The average annual precipitation ranges between 200 and 500 mm. Although a small country, Jordan has many different climatic regions; including sub tropical, Mediterranean, steppe and desert regions. Temperature and rain differences between these regions are wide, beside fluctuation in climate from one year to another. Climate change will add more stress on the natural renewable resources, especially on water and agriculture. In spite that most of agricultural areas in Jordan are rain-fed, the agriculture sector utilizes about two-thirds of the available water resources. The purpose of the study is to identify adaptation measures that would reduce climate change and water scarcity impacts on agricultural productivity and on crop production in particular. Adaptation measures were proposed based on results from assessment of climate change impacts on agricultural production. The adaptation for rainfed agriculture included the improvement of soil water storage to maximize the plant water availability; the application of conservation agriculture to reduce soil degradation; the improvement of soil fertility; the management of crop residue and tillage practices to conserve soil moisture; the modification of planting and harvesting dates for field crops and the selection of drought-tolerant crop varieties; the expansion of rainwater harvesting and management schemes; encouraging the farmers to adopt and apply the in-situ water harvesting systems (micro-catchment); developing strategies and plans for climate change adaptation and capacity building; and the improvement of extension services and technology transfer. Proposed autonomous adaptation measures included the enhancement of adaptive capacity of farmers to be more involved in decision-making and diversification of farmers' sources of income to minimize vulnerability to climate change.

    Jordan faces an archetypal combination of high water scarcity, with a per capita water availability of around 150 CM per year significantly below the absolute scarcity threshold of 500 CM, and strong population growth, especially due to the Syrian refugee crisis. This poses a severe challenge to the already strained institutions in the Jordanian water sector. The Stanford-led G8 Belmont Forum project "Integrated Analysis of Freshwater Resources Sustainability in Jordan" aims at analyzing the potential role of water sector institutions in the pursuit of a sustainable freshwater system performance. In order to do so, the project develops a coupled hydrological and agent-based model, allowing for the exploration of physical as well as socio-economic and institutional scenarios for Jordan's water sector. The part of this integrated model in focus here is the representation of household behavior in Jordan's densely populated capital Amman. Amman's piped water supply is highly intermittent, which also affects its potability. Therefore, Amman's citizens rely on various decentralized modes of supply, depending on their socio-economic characteristics. These include water storage in roof-top and basement tanks, private tanker supply, and the purchase of bottled water. Capturing this combination of centralized and decentralized supply modes is important for an adequate representation of water consumption behavior: Firstly, it will affect the impacts of supply-side and demand-side policies, such as reductions of non-revenue water (including illegal abstractions), the introduction of continuous supply, support for storage enhancements, and water tariff reforms. Secondly, it is also necessary to differentiate the impacts of any policy on the different socio-economic groups in Amman. In order to capture the above aspects of water supply, our model is based on the tiered supply curve approach, developed by Srinivasan et al. in 2011 to model a similar situation in Chennai, India. To tailor our model to the situation in Amman, we rely on sectoral data, existing literature analyses and expert discussions with Jordanian water sector representatives. Our modeling approach allows us to directly compare policies affecting both centralized and decentralized elements of the system within a common framework.

    This report is a supplement to previous accounts of geochemical exploration conducted in the Hashemite Kingdom of Jordan by the Natural Resources Authority of the Royal Government of Jordan and the U.S. Geological Survey. The field work on which this report is based was sponsored by the U.S. Agency for International Development, U.S. Department of State. Procedures used in collecting various kinds of rocks, ores, slags, eluvial and alluvial sediments, heavy-mineral concentrates, and organic materials for use as geochemical sample media are summarized, as are the laboratory procedures followed for the analysis of these sample materials by semiquantitative spectrographic, atomic absorption, fluorometric, and X-ray diffraction methods. Geochemical evaluations of the possibilities for economic mineral deposits in certain areas are presented. The results of these preliminary investigations open concepts for further use in geochemical exploration in the search for metallic mineral deposits in Jordan. Perhaps the most desirable new activity would be hydrogeochemical exploration for uranium and base metals, accompanied by interpretation of such remote-sensing data as results of airborne radiometric surveys and computer-enhanced LANDSAT imagery. For more conventional approaches to geochemical exploration, however, several fundamental problems regarding proper choice of geochemical sample media for different geologic and geographic parts of the Country must be solved before effective surveys can be made. The present results also show that such common geochemical exploration techniques as the determination of the trace-element contents of soils, plant ash, and slags have direct application also toward the resolution of several archaeological problems in Jordan. These include the relation of trace-elements chemistry of local soils to the composition of botanic remains, the trace-elements composition of slags to the technological development of the extractive metallurgy of copper and iron in the region, and the use of charcoal from slags for the C-14 dating of periods of archaeometallurgical activity. Less directly, interpretations based on the distribution in time and space of the archaeometallurgical activities of the region might add to the knowledge of early climatic conditions and vegetative cover of the area.

  15. Geophysical analysis of the recent sinkhole trend at Ghor-Haditha (Dead Sea, Jordan)

    For essentially the last 30 year the water level of the Dead Sea has highly dropped. One of the major associated facts is sinkhole occurrences along the shoreline both in Jordan and Israel. As the principal invoked mechanism, many studies have concluded that sinkhole formation results from the dissolution of a previously immersed salt layer, progressively in contact with fresh to brackish water. In Jordan, the triggering of this phenomenon could also be the result of particular tectonic settings, associated with the Jordan-Dead Sea transform fault system. At Ghor Haditha (south-est Jordan), the consequences have been dramatic for farmers with the shrinking of temporary available lands and industry with the closing of at least one factory. The shallow material in this area is heterogeneous and composed of intercalated sand and clay layers of alluvial-colluvial origin, over a salty substratum, whose precise depth and thickness are yet partially hypothesized. Between 2005 and 2008, a multi-method high-resolution geophysical survey was performed, approximately over a 1 km2 area at Ghor Haditha, associating mainly electromagnetic soundings, magnetic resonance soundings (MRS), and seismic profiling, ground-penetrating radar and electrical resistivity tomography. At the same time, this specific area was the location of a dramatic evolution of sinkhole occurences, regularly followed by geodetic measurements. Over the 3 years period, about 120 TEM (Transient ElectroMagnetic) soundings allow to map precisely the depth of the conductive layers below the resistive overburden. Two conductive layer are then revealed, the latter showing the lowest resistivity below 1 Ohm.m corresponding to the saline substratum. Several MRS (3 in 2005, repeated in 2007 and 12 additional soundings) show an east-west hydraulic gradient towards the Dead. However, the main sinkhole trend coincides with both: - a clear low transmissivity axis determined from MRS measurements; - the western side of a depression into the top of the most conductive layer. This shows so clearly a correlation between the recent sinkhole phenomenon and the current water circulations, but paleo-topography below the Pleistocene deposits mays equally be a clue in the sinkhole hazard.

  16. La structure de Jordan des matrices de transfert des modeles de boucles et la relation avec les hamiltoniens XXZ

    NASA Astrophysics Data System (ADS)

    Morin-Duchesne, Alexi

    Lattice models such as percolation, the Ising model and the Potts model are useful for the description of phase transitions in two dimensions. Finding analytical solutions is done by calculating the partition function, which in turn requires finding eigenvalues of transfer matrices. At the critical point, the two dimensional statistical models are invariant under conformal transformations and the construction of rational conformal field theories, as the continuum limit of these lattice models, allows one to compute the partition function at the critical point. Many researchers think however that the paradigm of rational conformal conformal field theories can be extended to include models with non diagonalizable transfer matrices. These models would then be described, in the scaling limit, by logarithmic conformal field theories and the representations of the Virasoro algebra coming into play would be indecomposable. We recall the construction of the double-row transfer matrix DN (λ, u) of the Fortuin-Kasteleyn model, seen as an element of the Temperley-Lieb algebra. This transfer matrix comes into play in physical theories through its representation in link modules (or standard modules). The vector space on which this representation acts decomposes into sectors labelled by a physical parameter d, the number of defects, which remains constant or decreases in the link representations. This thesis is devoted to the identification of the Jordan structure of DN(λ, u) in the link representations. The parameter β = 2 cos λ = -(q + q-1) fixes the theory : for instance β = 1 for percolation and 2 for the Ising model. On the geometry of the strip with open boundary conditions, we show that DN(λ, u) has the same Jordan blocks as its highest Fourier coefficient, FN. We study the non-diagonalizability of FN through the divergences of some of the eigenstates of ρ(F N) that appear at the critical values of λ. The Jordan cells we find in ρ(DN(λ, u)) have rank 2 and couple sectors d and d' when specific constraints on λ, d, d' and N are satisfied. For the model of critical dense polymers (β = 0) on the strip, the eigenvalues of ρ(DN(λ, u)) were known, but their degeneracies only conjectured. By constructing an isomorphism between the link modules on the strip and a subspace of spin modules of the XXZ model at q = i, we prove this conjecture. We also show that the restriction of the Hamiltonian to any sector d is diagonalizable, and that the XX Hamiltonian has rank 2 Jordan cells when N is even. Finally, we study the Jordan structure of the transfer matrix T N(λ, ν) for periodic boundary conditions. When λ = πa/b and a, b ∈ Z× , the matrix TN(λ, ν) has Jordan blocks between sectors, but also within sectors. The approach using FN admits a generalization to the present case and allows us to probe the Jordan cells that tie different sectors. The rank of these cells exceeds 2 in some cases and can grow indefinitely with N. For the Jordan blocks within a sector, we show that the link modules on the cylinder and the XXZ spin modules are isomorphic except for specific curves in the (q, ν) plane. By using the behavior of the transformation ĩd N in a neighborhood of the critical values (qc, ν c), we explicitly build Jordan partners of rank 2 and discuss the existence of Jordan cells with higher rank. Keywords : phase transitions, Ising model, Potts model, Fortuin-Kasteleyn model, transfer matrix method, XXZ Hamiltonian, logarithmic conformal field theory, Jordan structure.

    The Jordan Schnitzer Museum of Art in Eugene, Oregon, houses a remarkable permanent collection of Asian art and antiquities, modern art, and sculpture, and also hosts traveling exhibitions. In the winter and spring of 2011, a series of digital photographs by artist Chris Jordan, titled "Running the Numbers," was exhibited in the Coeta and Donald Barker Special Exhibitions Gallery. These works graphically illustrate waste (energy, money, health, consumer objects, etc.) in contemporary culture. The Bonneville Power Administration and the Eugene Water and Electricity Board provided a set of Cree 12W light-emitting diode (LED) PAR38 replacement lamps (Cree LRP38) for the museum to test for accent lighting in lieu of their standard Sylvania 90W PAR38 130V Narrow Flood lamps (which draw 78.9W at 120V). At the same time, the museum tested LED replacement lamps from three other manufacturers, and chose the Cree lamp as the most versatile and most appropriate color product for this exhibit. The lamps were installed for the opening of the show in January 2011. This report describes the process for the demonstration, the energy and economic results, and results of a survey of the museum staff and gallery visitors on four similar clusters of art lighted separately by four PAR38 lamps.

    The development of the dairy industry plays an important role in the economy of Middle Eastern countries. Judged by its growth rate, the dairy industry is viewed as one of the most progressive food industries in the Middle East. During the early 1970s, countries established executive programs to promote dairy farming; the major objective was to attain self-sufficiency in milk production. A massive investment was set up for importing top class cattle, complying with top industry operating standards, and a simultaneous introduction of the latest technology in processing, packaging, and distributing. Milk production has grown tremendously at rates of 6.6% and 4.9% in Syria and Saudi Arabia, respectively, between 2002 and 2007, which resulted in these nations being almost self-sufficient. Regarding Jordan, milk production has not yet met this target. An excessive growth in the dairy industry is quite noticeable in this region with an expanding capacity for exports. The aim of this study is to show the most recent trends and future prospects of the dairy industries in Syria, Saudi Arabia, and Jordan. It also attempts to investigate the drivers for the development of milk production, consumption, and trade in the region. PMID:20352329

    Dogs are competent reservoir hosts of several hemopathogens including zoonotic agents and can serve as readily available source of nutrition for many blood-feeding arthropods. Three hemopathogens had been detected for the first time in Jordan. The PCR prevalence of Anaplasma phagocytophilum, Hepatozoon canis, and piroplasmid DNA were 39.5%, 28.9%, and 7.9% (n=38) respectively. Sequencing of amplicons of PCR with universal primers targeting the 18S rRNA gene of piroplasmids shows the highest similarity to equine piroplasmids species Theileria equi from two dogs and Babesia caballi from a single dog. Ticks of two genera Rhipicephalus and Haemaphysalis, were detected in this study (n=268). The brown dog tick, Rhipicephalus sanguineus was the most abundant species (95.1%, n=255), followed by Haemaphysalis erinacei (3%, n=8) and Haemaphysalis parva (1.9%, n=5). The two Haemaphysalis species were detected for the first time from dogs in Jordan. Regarding its high prevalence, we expect R. sanguineus being a possible vector of detected pathogens.

    The purposes of this study were to estimate the seroprevalence and distribution of horse piroplasmosis, to evaluate risk factors associated with the occurrence of the disease and to compare the different diagnostic methods used for this disease. A total of 253 clinically normal horses were sampled, and a collection form was completed for each horse from five of six different climatic zones of Jordan. The sixth zone was not sampled because it did not include horse population. Competitive enzyme-linked immunosorbent assay (cELISA) revealed 37 horses (14.6%) positive for Theileria equi, and none of the horses was positive for Babesia caballi. Microscopic examination of thin blood smears and PCR test revealed no positive results for either parasite. Grazing was the only risk factor that was associated with being seropositive to the disease; horses that graze are 11.5 more likely to be seropositive (P<0.05, OR=11.5, CI: 3.292, 39.962). This is the first study to estimate the prevalence of horse babesiosis using serological test and to identify risk factors associated with the disease in Jordan. Competitive enzyme-linked immunosorbent assay (cELISA) test appears to be more reliable than microscopic examination and PCR in estimating the seroprevalence of the disease as well as identifying carrier horses to babesiosis.

    Over thirty wells for exploration and production purposes were drilled in the Risha Area, northeast Jordan by the Natural Resources Authority since 1986. Commercial gas was discovered in the sandstones of Dubeidib Formation (Late Ordovician age). These sandstones are believed to have been deposited in the form of marine sand bars trending NNE-SSW. During the Early Paleozoic time, Jordan has undergone periods of epirogenic movements ending in Late Ordovician. Two major lineament trends are dominant, one oriented northwest-southeast and the other ENE-WSW. A third trend oriented north-south to NNW-SSE also appears but more discontinuous. Four source rock horizons were developed within the Early Paleozoic times. Oil generation of Lower Paleozoic source horizons took place in the Late Paleozoic. The upper Mudawwara hot shales of Silurian age is believed to have generated liquid hydrocarbons in the Late Cretaceous times, in a second phase of hydrocarbon generation. Dry gas was originated through organic maturation of the Lower Paleozoic source horizons. The Risha Gas Field is producing 30 MMcfgd since it was first discovered in 1987.

  3. KAr ages, chemical composition and geothermal significance of cenozoic basalt near the Jordan rift

    Late Cenozoic mafic lavas crop out locally along the Jordan rift. Some of these lavas are spatially associated with thermal springs, and this association has prompted some workers to hypothesize that the hot water derives its thermal energy from the shallow, still hot intrusive roots of the volcanic rocks. However, all of the volcanic rocks appear to represent mantle-derived mafic magma that rose rather quickly to the Earth's surface, without filling crustal reservoirs within which differentiation would have produced evolved, derivative products. Moreover, the lavas are too old and of too small a volume to represent the surface expression of an active reservoir of magma within the crust. These interpretations of the volcanic geology are consistent with conclusions drawn from the chemistry of the thermal water; the water has equilibrated with host rocks at no more than 110??C, probably at depths of 2-3 km. Thus, thermal springs along the Jordan rift appear to reflect heating during circulation through a regional regime of average crustal heat flow (Galanis et at., 1986). The magmatic activity may only be a second or third order contributor to this heat flow. ?? 1988.

    This document is an analysis of options for unilateral and cooperative action to improve the security of Jordan's borders. Sections describe the current political, economic, and social interactions along Jordan's borders. Next, the document discusses border security strategy for cooperation among neighboring countries and the adoption of confidence-building measures. A practical cooperative monitoring system would consist of hardware for early warning, command and control, communications, and transportation. Technical solutions can expand opportunities for the detection and identification of intruders. Sensors (such as seismic, break-wire, pressure-sensing, etc.) can warn border security forces of intrusion and contribute to the identification of the intrusion and help formulate the response. This document describes conceptual options for cooperation, offering three scenarios that relate to three hypothetical levels (low, medium, and high) of cooperation. Potential cooperative efforts under a low cooperation scenario could include information exchanges on military equipment and schedules to prevent misunderstandings and the establishment of protocols for handling emergency situations or unusual circumstances. Measures under a medium cooperation scenario could include establishing joint monitoring groups for better communications, with hot lines and scheduled meetings. The high cooperation scenario describes coordinated responses, joint border patrols, and sharing border intrusion information. Finally, the document lists recommendations for organizational, technical, and operational initiatives that could be applicable to the current situation.

    Modern water systems can be characterized by a complex network of institutional and private actors that represent competing sectors and interests. Identifying solutions to enhance water security in such systems calls for analysis that can adequately account for this level of complexity and interaction. Our work focuses on the development of a hierarchical, multi-agent, hydroeconomic model that attempts to realistically represent complex interactions between hydrologic and multi-faceted human systems. The model is applied to Jordan, one of the most water-poor countries in the world. In recent years, the water crisis in Jordan has escalated due to an ongoing drought and influx of refugees from regional conflicts. We adopt a modular approach in which biophysical modules simulate natural and engineering phenomena, and human modules represent behavior at multiple scales of decision making. The human modules employ agent-based modeling, in which agents act as autonomous decision makers at the transboundary, state, organizational, and user levels. A systematic nomenclature and conceptual framework is used to characterize model agents and modules. Concepts from the Unified Modeling Language (UML) are adopted to promote clear conceptualization of model classes and process sequencing, establishing a foundation for full deployment of the integrated model in a scalable object-oriented programming environment. Although the framework is applied to the Jordanian water context, it is generalizable to other regional human-natural freshwater supply systems.

    Pediculosis capitis (head lice infestation) is a worldwide public health concern affecting mostly primary-school children. In a cross-sectional study in 2009/2010, the prevalence of pediculosis capitis and some risk factors for infestation were investigated among 1550 randomly selected primary-school children in Mafraq governorate, Jordan. The prevalence of pediculosis capitis was 26.6%. There were significant differences in the prevalence between girls (34.7%) and boys (19.6%), rural (31.2%) and urban (23.5%) residents, and history of infestation in the previous year (57.4%) versus no history (11.5%), as well as between children of different ages, family size and income (P<0.001). Longer hair length, lack of bathing facilities, low frequency of hair-washing and bathing, and sharing of articles (e.g. combs, scarves) were significantly associated with infestation (P<0.001). The prevalence of infestation was higher than reported in previous studies in Jordan (< 14%). Programmes are needed to increase awareness of pediculosis capitis and the importance of good personal hygiene. PMID:22360010

  7. Rapid landscape change in 6th century Jordan: driven by climate or man-made?

    Compared to the rich cities of antiquity, many areas in the Levant appear today degraded. European travel reports of the 19th century and excavations in Jordan created the impression that population numbers were strongly reduced during the Islamic periods, leading to 'empty' lands which were only resettled during the early 20th century. However, our case study near the ancient site Abila of the Decapolis in northern Jordan found that the land was probably never 'empty' and always fertile - but valley fills provide evidence for a rapid and intense landscape change during the Late Byzantine period. This was probably caused by a significant shift to aridity which also triggered socio-economic changes of subsistence strategies from agriculture to pastoralism. The dates of sediments which are available so far indicate that the climatic change seemingly occurred rapidly within approximately 100 years during the late 6th and early 7th century AD, and rubble layers let it seem probable that it was associated with frequent heavy rainfall events. It might have been caused or triggered by a global climate event creating the "year without sun" or 'Mystery Veil' which the Byzantine historian Procopius described in the year 536 AD. If similar events repeat under the current climate change, it will be difficult to mitigate them.

    Archaeological damage in buried ruins often offers an excellent record of recent tectonic activity. The lower Jordan valley has experienced a continuous occupation in the last 5000 year, being frequent archaeological remains of human settlements along the valley. In this work we studied the Early Neolithic-to-Middle Islamic Periods archaeological site of Tall al-Hammam (Arabic name, ¨Hill of Baths¨). This ruin is located 27 km southwest of Amman city and it constitutes the largest Bronze Age archaeological site in Jordan. It consists of two main parts; the Upper Tall and the Lower Tall. This ruin lies within the southwestern termination of the Shueib structure (SHS); a Cretaceous fold-bend fault structure thought inactive through the entire Cenozoic. The relics, in the lower Tall, show clear fault-related damage in some walls. Two Middle Bronze Age (MBA) walls are displaced 26 and 20 cm respectively, according with a NNE-SSW fault plane. Apart of wall displacements, hundreds of joints and cracks in boulders of the walls are present. They strike generally NW-SE and NE-SW. Both archaeological evidences, boulder fractures and walls distortion, are coherent with the present-day tectonic setting of the Dead Sea Transform Fault in the region, and suggest a Quaternary reactivation of the SHS.

    In order to alleviate diabetic foot problems, patients sometimes seek complementary therapies outside the professional context. This paper describes the use of complementary remedies as a topical treatment for diabetic foot ulcers among Jordanians. Qualitative content analysis was used to analyse written responses of 68 patients with diabetes who have used complementary therapies to treat diabetic foot problems. These 68 persons represented a subgroup of the study population surveyed using a questionnaire, to the effect of investigating diabetic foot treatments provided in Jordan. Informants were recruited from eight healthcare facilities established in the southern part of Jordan plus from one hospital established in the Jordanian capital. The study was approved by the Boards of Ethics of the participating healthcare facilities. Content analysis yielded the category "Complementary Therapies Used", which included a range of household items (olive oil, sesame oil, honey, and vinegar), and also some indigenous Jordanian herbs (Wormwood, Myrrh, Caper, and Henna among others). The remedies were used either as a monotherapy or as mixtures, to the common goal of treating diabetic foot problems. Other interventions like Al-cowy were also sought from traditional healers. Educational campaigns are required to increase the awareness of patients and their families on possible hazards of unwise complementary therapy use. The decisions on the use of such therapies should be made in agreement with the attending healthcare professionals. PMID:23983379

    The aim of this cross-sectional study was to assess the knowledge about epilepsy and the attitudes toward people with epilepsy (PWE) and their predictors among university students in Jordan. A self-administered questionnaire was distributed in three of the largest public universities in Jordan, and a total of 500 questionnaires were collected from each university. The number of students who reported that they had heard or read about epilepsy was 1165 (77.6%), and their data were analyzed. A significant proportion of students thought that epilepsy could be caused by the evil spirit (31.5%) and the evil eye (28.1%) or that it could be a punishment from God (25.9%). Epilepsy's most commonly reported treatment methods were the Holy Quran (71.4%), medications (71.3%), and herbs (29.3%). The most common negative attitudes toward PWE were that the students would refuse to marry someone with epilepsy (50.5%) and that children with epilepsy must join schools for persons with disabilities (44.4%). Male students, students of humanities, and students with a low socioeconomic status tended to have more negative attitudes toward PWE. In conclusion, many students have misconceptions about the causes, treatment, and nature of epilepsy, and students have moderate negative attitudes toward PWE. Universities should have health promotion programs to increase awareness of their students about major public health problems such as epilepsy. PMID:25461223

    Monitoring of radon gas ((222)Rn) in Jordan was started in the early 1990s. Since then our radon group at Yarmouk University and others have carried out tens of studies that include measurements of indoor radon, radon in water, radon in soil and radon emanating from building materials. All major cities of Jordan had been surveyed, from the northern city of Irbid down to the southern port city of Aqaba. Most of these studies were carried out by using time-integrated passive radon dosimeters containing CR-39 solid-state nuclear track detectors. In addition to that, an active radon monitor was used to study the seasonal variation of (222)Rn in Al-Ruseifa that lies near abandoned phosphate mines and in Amman area. During such a study passive dosimeters were also used. The average radon concentrations in dwellings in Jordanian cities ranged from about 20 to 386 Bq/m(3) with the highest readings exhibited during the winter season around the town of Al-Ruseifa.

    As in many other developing countries, the generation of regulated medical waste (RMW) in Jordan has increased significantly over the last few decades. Despite the serious impacts of RMW on humans and the environment, only minor attention has been directed to its proper handling and disposal. This study was conducted in the form of a case study at one of Jordan's leading medical centers, namely, the King Hussein Medical Center (KHMC). Its purpose was to report on the current status of medical waste management at KHMC and propose possible measures to improve it. In general, it was found that the center's administration was reasonably aware of the importance of medical waste management and practiced some of the measures to adequately handle waste generated at the center. However, it was also found that significant voids were present that need to be addressed in the future including efficient segregation, the use of coded and colored bags, better handling and transfer means, and better monitoring and tracking techniques, as well as the need for training and awareness programs for the personnel.

    The prevalence of metabolic syndrome is increasing worldwide and exhibits variation among ethnic groups. The objective of this study was to estimate and compare the prevalence of metabolic syndrome and its components between two ethnic groups (Circassians and Chechens) in Jordan and the original inhabitants of Jordan. Data were collected from a cross-sectional study of Circassian (n = 436), Chechen (n = 355), and Jordanian (n = 3234) population aged 18 years and older. Metabolic syndrome was defined according to International Diabetes Federation criteria. Age-standardized prevalence rate of metabolic syndrome was Jordanians 38.0 %, Circassians 32.0 %, and Chechens 33.7 %. Compared to Jordanians, both minority groups had lower means of body mass index, total cholesterol, fasting blood glucose, and triglycerides. The means of high-density lipoprotein and low-density lipoprotein were significantly higher among Circassians compared to Jordanians and Chechens. The odds of BMI defined by overweight and obesity and diabetes were less common among Circassians and Chechens compared to Jordanians. The prevalence of the metabolic syndrome and its individual components is relatively high in the three ethnic groups compared to world. Variation in components between groups may relate to ethnicity. Therefore, a community-based integrated approach is needed that would include behavioral, social changes that would lead to the prevention and treatment of the metabolic syndrome. PMID:22740093

    Foodborne toxoplasmosis is a leading cause of foodborne deaths and hospitalization worldwide. The level of exposure to Toxoplasma gondii is influenced by culture and eating habits. There is a scarcity of data about women's knowledge and perception of this disease. The aim of this study was to determine toxoplasmosis knowledge and preventive practices of young childbearing age women in Jordan. A descriptive cross-sectional study recruited a random sample of 1,390 undergraduate university female students and was stratified based on place of residency. About half of students (51.1%) reported having "ever" heard or read about toxoplasmosis, and almost all students (98.6%) had never been tested for toxoplasmosis. Overall, there was a lack of awareness about toxoplasmosis, its risk factors, symptoms, and timing of infection, and preventive practices. High percentages of females reported a high level of hygienic practices related to hand washing after gardening, changing cat litter, and handling raw meat. However, 16.7% of students reported eating raw meat, 26.5% usually eat traditional herbs, and 17.2% drink untreated spring water. This study establishes a baseline for the awareness levels about toxoplasmosis among young women in Jordan. These findings highlight the urgent need for toxoplasmosis awareness and preventive education for childbearing females. An effective education and outreach program should cover important topics concerning risk factors, high-risk foods, and preventive measures against toxoplasmosis. PMID:26038907

    Goat production is an important agricultural activity in Jordan. The country is one of the poorest countries in the world in terms of water scarcity. Provision of sufficient quantity of good quality drinking water is important for goats to maintain feed intake and production. This study aimed to evaluate the seasonal availability and quality of goats' drinking water sources, accessibility, and utilization in different zones in the Karak Governorate in southern Jordan. Data collection methods comprised interviews with purposively selected farmers and quality assessment of water sources. The provision of drinking water was considered as one of the major constraints for goat production, particularly during the dry season (DS). Long travel distances to the water sources, waiting time at watering points, and high fuel and labor costs were the key reasons associated with the problem. All the values of water quality (WQ) parameters were within acceptable limits of the guidelines for livestock drinking WQ with exception of iron, which showed slightly elevated concentration in one borehole source in the DS. These findings show that water shortage is an important problem leading to consequences for goat keepers. To alleviate the water shortage constraint and in view of the depleted groundwater sources, alternative water sources at reasonable distance have to be tapped and monitored for water quality and more efficient use of rainwater harvesting systems in the study area is recommended.

    Many environment problems of the full using of several categories of processing include mining, heat generators, direct combustion of forest fires, cement production, power plant, transport, medical waste. Dioxin/furan releases from these categories are one of these environment problems. Possible lines of reducing the PCDD/PCDF (Polychlorinated dibenzo-para-dioxins/Polychlorinated dibenzofurans) releases from these categories are elucidated. The contribution of this paper is present the identification and estimation of the latest figure of dioxin/furan releases in the climate of environment of Jordan in the period 2000-2008 from the following categories (cement, aluminum, ceramic, medical waste, power plant, land fill, ferrous and non-ferrous metals, uncontrolled combustion process (biomass burning, waste burning, accidental fires in house, transport). These finding shows the sign of growth of estimated PCDD/PCDF releases from categories which did not calculated and followed after 2003. The result shows the highest PCDD/PCDF release from landfill fires (62.75 g TEQ/year), medical waste (8.8264 g TEQ/year), and transport (3.0145 g TEQ/year). Jordan seeks by next years, a reduction in total releases of dioxins and furans from sources resulting from human activity. This challenge will apply to the aggregate of releases to the air nationwide and of releases to the water within the Jordan area. Jordan should conduct air monitoring for dioxin in order to track fluctuations in atmospheric deposition levels.

    1999-01-01

    An aquifer test of the Prairie du Chien-Jordan aquifer was conducted in the Shakopee Mdewakanton Sioux Community located southwest of the Twin Cities metropolitan area. A well open to the Jordan Sandstone was pumped at 600 gallons per minute for 57 hours. Drawdown was monitored in three observation wells located near the pumped well. These wells were open to: (1) the Jordan Sandstone, the principal unit of the aquifer; (2) the Prairie du Chien Group, a secondary, carbonate-rock unit of the aquifer; and (3) a confined, glacial-drift sand aquifer. Test results indicate that the Jordan Sandstone had a transmissivity of 6,267 ft2/d, a storativity of 1.193 x 10-4, a horizontal hydraulic conductivity of 31 ft/d based on a saturated thickness of 204 ft, and a ratio of vertical to horizontal hydraulic conductivity of 5.29 x 10-4. The pumped well was hydraulically connected to the Prairie du Chien Group observation well. No drawdown was observed in the observation well completed in the confined, glacial-drift sand aquifer; thus, a hydraulic connection of this observation well to the pumped well was not indicated.

    The nonsymmetric Kaluza-Klein (Jordan-Thiry) theory leads to a model of a modified acceleration that can fit an anomalous acceleration experienced by the Pioneer 10 and 11 spacecraft. A mysterious connection between an anomalous acceleration and a Hubble constant is solved in the theory.

  16. Facing Water Scarcity in Jordan: Reuse, Demand Reduction, Energy and Transboundary Approaches to Assure Future Water Supplies

    NASA Astrophysics Data System (ADS)

    2001-05-01

    Jordan is extremely water-scarce with just 170 cubic meters per capita per year to meet domestic, industrial, agricultural, tourism, and environmental demands for water. Given the natural climatological conditions, demographic pressure, and transboundary nature of water resources, all renewable water resources of suitable quality are being exploited and some non-renewable aquifers are being depleted. The heavy exploitation of water resources has contributed to declines in the level of the Dead Sea. Rapid growth in demand, particularly for higher quality water for domestic, industrial and tourism uses, is significantly increasing pressure on agricultural and environmental uses of water, both of which must continue to adapt to reduced volumes and lower quality water. The agricultural sector has begun to respond by improving irrigation efficiency and increasing the use of recycled water. Total demand for water still exceeds renewable supplies while inadequate treatment of sewage used for irrigation creates potential environmental and health risks and presents agricultural marketing challenges that undermine the competitiveness of exports. The adaptive capability of the natural environment may already be past sustainable limits with groundwater discharge oasis wetlands that have been seriously affected. Development of new water resources is extremely expensive in Jordan with an average investment cost of US\\$ 4-5 per cubic meter. Integrated water resources management (IWRM) that incorporates factors external to the 'water sector' as conventionally defined will help to assure sustainable future water supplies in Jordan. This paper examines four IWRM approaches of relevance to Jordan: water reuse, demand management, energy-water linkages, and transboundary water management. While progress in Jordan has been made, the Ministry of Water and Irrigation continues to be concerned about the acute water scarcity the country faces as well as the need to continue working with concerned stakeholders to assure future water supplies.

  17. Hydrogeochemical investigation of groundwater in Jericho area in the Jordan Valley, West Bank, Palestine

    2013-06-01

    Water resources in the Middle East, particularly in Palestine, are extremely scarce and costly. The Jordan Valley is a fertile productive region, described as the food basket of Palestine. Groundwater originating from the Quaternary Aquifer System forms the main water resource in the Jordan Valley. However, the quality of this groundwater is threatened mainly by the high chloride concentration. The most representative area of the Jordan Valley is Jericho area, which was chosen to be the study area. The study area (65 km2) is almost a flat area with a gentle decline towards the east. It is the lowest land on earth with ground levels reaching 400 meters below sea level (mbsl) near the Dead Sea shores. The Quaternary Aquifer System in the study area could be divided into an upper alluvial layer with thickness varying from 40 to 150 m and a lower low-permeable Lisan layer, which crops out in the eastern part of the study area with thickness over 200 m. Hydrogeochemical investigation reveals that the water is generally earth alkaline with higher content of earth alkalis and prevailing chloride. According to Stuyfzand (1986) and Piper's (1944) classification systems, water type in the Alluvial Aquifer varies from fresh hard CaMgHCO3 or MgCaHCO3 water in the west and northwest to brackish very-hard MgNaCl or NaMgCl in the middle. In the east, the water becomes brackish-salt extremely-hard MgNaCl or NaCl. Groundwater quality is deteriorating (increase in salinity) spatially towards the east and vertically with increasing depth (when nearing the Lisan Formation). As an indication of groundwater salinity, total dissolved solids show some variability with time over the last 21 years (1983-2004). In short-time scale, there are high seasonal and yearly fluctuations with regard to salinity, specifically in Cl- and SO42- contents. Spring water from the Upper Cenomanian Aquifer (CaHCO3) represents the fresh end member, while Rift Valley Brines (RVB-CaNaCl) and Dead Sea Brines (DSB-MgNaCl) represent the saline end members. Existing water types are mixtures of the 3 end members. There is a consistency in results and analysis of geological, hydrogeological, hydrochemical and geophysical data. There are three probable sources of increase in groundwater salinity: mixing with saline end members (RVB/DSB); dissolution of minerals of the Lisan Formation (calcite, dolomite, gypsum and halite); and to some extent, agricultural effluent pollution.

  18. Land degradation causes and sustainable land management practices in southern Jordan

    2014-05-01

    Jordan is one of the world's most water-deficit countries with only about 4% of the total land area considered arable. As a consequence agricultural production is greatly constrained by limited natural resources. Therefore, a major challenge for the country is to promote the sustainable use of natural resources for agricultural purposes. This challenge is being made harder by the ongoing processes of degradation due to increased population pressure, which undermine any social and economic development gains. In the southern plains of Jordan, sustainability of farming practices has worsened in the past three decades, exacerbating pressure on land and increasing land degradation processes. Non-sustainable land use practices include improper ploughing, inappropriate rotations, inadequate or inexistent management of plant residues, overgrazing of natural vegetation, random urbanization, land fragmentation and over-pumping of groundwater. The root cause is the high population growth which exerts excessive pressure on the natural resources to meet increased food and income demand. The poorest farmers who are increasingly growing cereals on marginal areas. Wheat and barley are now grown with little to no rotation, with no nutrient replenishment, and at places avoiding even fallow. Small landholding sizes and topographic features of the area tend to oblige longitudinal mechanized tillage operations along the slopes. Overall, the constraints facing the deprived land users such as, poor access to technology, capital and organization are the factors that lead into unsustainable practices. The main bottlenecks and barriers that hinder mainstreaming of sustainable land management in Jordan can be grouped into three main categories: (i) Knowledge, (ii) Institutional and Governance, and (iii) Economic and Financial. In this case study, the key challenge was to create a knowledge base among local stakeholders - including planners, extension officers, NGO/community leaders, teachers, farm owners, and farm workers - to support the inclusion of sustainable land management while sustaining ecosystem services and livelihoods. Also, we demonstrated and focused on practical understanding of how to identify and address land degradation and on using sustainable land use practices - including soil and water conservation measures, conservation agriculture, and rangeland management- through combination of expert and participatory research and participatory planning.

    The mycoflora of the hair in 178 goats from the West Bank of Jordan was analysed and the frequency of occurrence and the relative importance value for the different keratinophilic fungi found were calculated. One hundred and seven species which belong to 38 genera were isolated. Thirty six of these species were either well recognised agents of mycoses (Trichophyton mentagrophytes, T. verrucosum, and M. nanum), or have been frequently isolated from human and animal lesions (Arthroderma spp., Acremonium kiliense, Alternaria alternata, Aspergillus flavus, Cladosporium carionii, and several other species). These potentially pathogenic fungal species comprised 66.9% of all keratinophilic fungi found on the hair of goats. The role of this animal as a reservoir for dermatophytes and other potentially pathogenic fungi is discussed. PMID:3221912

  20. Atmospheric heavy metal pollution in Aqaba city, Jordan, using Phoenix dactylifera L. leaves

    Al-Khlaifat, Abdelaziz L.; Al-Khashman, Omar A.

    The leaves of date palms ( Phoenix dactylifera L.) were evaluated as biomonitors of heavy metal contamination in the city of Aqaba, Jordan. The concentrations of iron (Fe), lead (Pb), zinc (Zn), copper (Cu), nickel (Ni), and chromium (Cr) were determined using a flame atomic absorption spectrophotometer. Samples of unwashed leaves for testing were collected from different locations with different degrees of metal pollution (urban, suburban, industrial, highway, and rural sites). Separate leaves were taken from outside the city to be used as a control sample. Samples collected from industrial areas were found to have high contents of all metals except for nickel, copper, and lead, which were found at high concentrations in the samples collected from highway sites. Significant correlations between the heavy metal concentrations in date palm trees in unwashed leave samples were obtained. The principle component analysis (PCA) along with correlation analysis provide significant information about the origin of heavy metals in palm tree samples.

    Historians of science account the appearance of textbooks as an important step in the formation and consolidation of a new discipline. The texts of Park and Jordan were both very important in this light; however; they also can be used as a gauge of changing concepts within microbiology in the first four decades after its consolidation as a discipline, 1900-1940. This paper tracks these important texts and through them changing attitudes toward several important concepts: bacterial variation, human/bovine tuberculosis, and the existence of a non-symptomatic carrier state in infectious disease. The two texts are also compared regarding their view of microbes as pathogens vs. microbes as important and ubiquitous ecological agents. Images Figure 1 Figure 2 PMID:11049163

    Many areas in Jordan suffer from elevated levels of coarse particulate matter (PM10). One potentially significant source of the observed PM is the resuspension of road dust in the vicinity of limestone quarries. To obtain data to assess the impact from this source, PM10 road dust resuspension factors near Abusiiah, a town to the north east of Amman surrounded by many quarries and brick factories, were measured. Measurements included PM10 mass, particle size distributions, wind speed, and wind direction. The results showed that PM10 concentrations could be as high as 600 microg/m3, and most of the airborne PM is in the coarse fraction. Loading trucks play a major role in resuspending road dust, with an observed PM10 emission rate of >6000 mg/km.

    This study examines the association between intimate partner violence (IPV) and women's experience of interference with their attempts to avoid pregnancy among 353 women surveyed at reproductive health clinics throughout Jordan. Approximately 20 percent of respondents indicated that their husbands or someone else had interfered. Among those others than husbands who were identified, mothers-in-law were the most frequently mentioned, followed by the respondents' mothers and sisters-in-law. Multivariate logistic regression was used to control for potential confounders in determining whether each of the three measures of intimate partner violence (physical violence, sexual violence, and controlling behaviors) was significantly associated with having an increased risk of experiencing interference, as were several sociodemographic variables: nonconsanguineous marriage, residence with in-laws, and rural residence. Physicians, nurses, and family planning counselors must be made aware of the challenges that women may face from their families when they attempt to regulate their fertility. PMID:18678176

    Cervical smears taken from women referred for a check-up or with vaginal itching/discharge over a period of 3.5 years were reviewed at the King Hussein Medical Centre, Jordan. All smears were fixed with 96% alcohol, stained with Papanicolaou stain and screened microscopically. Of the smears from 1176 women aged 18-70 years, 4.5% were classified as inadequate, 7.7% were normal and 79.9% showed non-specific inflammation. Abnormal vaginal flora was found in 4.8% of cases, Candida albicans in 1.2%, Trichomonas vaginalis in 0.9% and actinomycosis in 1 case. Dysphasic changes were rare: 9 cases (0.8%) were classified as atypical squamous cells of undetermined significance (ASCUS) and 2 cases (0.2%) were low-grade squamous intraepithelial lesion (LSIL). No cases of human papillomavirus infection (HPV) or cervical carcinoma were found. PMID:16335662

    The rate of psychiatric morbidity and its sociodemographic correlates was estimated in 2000 women attending 3 primary care centres in Irbid, Jordan. Women completed standardized diagnostic tools that yielded psychiatric diagnoses, a stress scale and sociodemographic details. The rate of psychiatric morbidity was 26.3% and psychological distress 39.0%. A significant association was found between the amount and severity of stress and psychiatric morbidity. Post-marital status (separated, divorced, widowed), woman's illiteracy, family violence, violent marital relationship, living independently, being in a non-cousin marriage, being a second wife, poor housing and absence of a social support system were significantly associated with psychiatric morbidity in this group of women.

    An effort to investigate the potential of remote sensing for monitoring nonpoint source pollution was conducted. Spectral reflectance characteristics for four types of soil sediments were measured for mixture concentrations between 4 and 173 ppm. For measurements at a spectral resolution of 32 mm, the spectral reflectances of Calvert, Ball, Jordan, and Feldspar soil sediments were distinctly different over the wavelength range from 400 to 980 nm at each concentration tested. At high concentrations, spectral differences between the various sediments could be detected by measurements with a spectral resolution of 160 nm. At a low concentration, only small differences were observed between the various sediments when measurements were made with 160 nm spectral resolution. Radiance levels generally varied in a nonlinear manner with sediment concentration; linearity occurred in special cases, depending on sediment type, concentration range, and wavelength.

  8. Chameleon effect in the Jordan frame of the Brans-Dicke theory

    In this paper we investigate the chameleon effect in the different conformal frames of the Brans-Dicke (BD) theory. Given that, in the standard literature on the subject, the chameleon is described in the Einstein frame almost exclusively, here we pay special attention to the description of this effect in the Jordan and in the string frames. It is shown that, in general, terrestrial and solar system bounds on the mass of the BD scalar field, and bounds of cosmological origin, are difficult to reconcile at once through a single chameleon potential. We point out that, in a cosmological context, provided that the effective chameleon potential has a minimum within a region of constant density of matter, the Brans-Dicke theory transmutes into general relativity with a cosmological constant, in that region. This result, however, can be only locally valid.

    Understanding and improving the health status of communities depend on effective public health surveillance. Adoption of new technologies, standardised case definitions and clinical guidelines for accurate diagnosis, and access to timely and reliable data, remains a challenge for public health surveillance systems however and existing public health surveillance systems are often fragmented, disease specific, inconsistent and of poor quality. We describe the application of an enterprise architecture approach to the design, planning and implementation of a national public health surveillance system in Jordan. This enabled a well planned and collaboratively supported system to be built and implemented using consistent standards for data collection, management, reporting and use. The system is case-based and integrated and employs mobile information technology to aid collection of real-time, standardised data to inform and improve decision-making at different levels of the health system.

    Plant species have long been regarded as possessing the principal ingredients used in widely disseminated ethnomedical practices. Different surveys showed that medicinal plant species used by the inhabitants of Jordan for the traditional treatment of diabetes are inadequately screened for their therapeutic/preventive potential and phytochemical findings. In this review, traditional herbal medicine pursued indigenously with its methods of preparation and its active constituents are listed. Studies of random screening for selective antidiabetic bioactivity and plausible mechanisms of action of local species, domesticated greens, or wild plants are briefly discussed. Recommended future directives incurring the design and conduct of comprehensive trials are pointed out to validate the usefulness of these active plants or bioactive secondary metabolites either alone or in combination with existing conventional therapies.

    This study is a catalogue of Dictyoptera (Mantodea, Isoptera and Blattaria) from five Eastern Mediterranean countries (Syria, Lebanon, Turkey, Iraq and Jordan). There are 75 species of Dictyoptera known to occur in these countries. These species belong to 15 families (eight of Mantodea, four of Isoptera and three of Blattaria). Mantodea is by far the dictyopteran group with the highest richness with 43 species occurring in this region, followed by Blattaria, with 21, and Isoptera with 11. Turkey is the place with the highest number of Dictyoptera (34%), followed by Iraq (23%) then Syria (22%), Jordan (15%) and Lebanon (7%). An analysis of accumulated number of species along time shows that most of this biodiversity was described during the 20th century, and that Mantodea is the group with the highest number of species described more recently. If this curve is taken as an estimator of the increase of diversity with new prospections, this indicates that the number of Mantodea in this region would be much higher than presently known. Conversely, the local richness of Blattaria and Isoptera are likely to be close to the present numbers, as the curves remain steady for about 100 years. An accumulation curve of species described with occurrence restricted to these five countries shows that most of them were described at the beginning of the 20th century. An analysis of the number of references dealing with each of these species along time reveals that Mantodea is the dictyopteran group most studied in all periods except the second half of the 20th century, when Isoptera was more cited. The types of these species are distributed in 29 institutions, but are mainly concentrated in four major European collections. PMID:25947764

    The objective of this study was to assess the extent and severity of metal contamination in urban soil around Queen Alia Airport, Jordan. Thirty-two soil samples were collected around steel manufacturing plants located in the Al-Jiza area, south Jordan, around the Queen Alia Airport. The samples were obtained at two depths, 0-10 and 10-20 cm, and were analyzed by atomic absorption spectrophotometry for lead (Pb), zinc (Zn), cadmium (Cd), iron (Fe), copper (Cu) and chromium (Cr) levels. The physicochemical factors believed to affect the mobility of metals in the soil of the study area were also examined, including pH, electrical conductivity, total organic matter, calcium carbonate (CaCO(3)) content and cation exchange capacity. The high concentrations of Pb, Zn and Cd in the soil samples were found to be related to anthropogenic sources, such as the steel manufacturing plants, agriculture and traffic emissions, with the highest concentrations of these metals close to the site of the steel plants; in contrast the concentration of Cr was low in the soil sampled close to the steel plants. The metals were concentrated in the surface soil, and concentrations decreased with increasing depth, reflecting the physical properties of the soil and its alkaline pH. The mineralogical composition of the topsoil, identified by X-ray diffraction, was predominantly quartz, calcite, dolomite and minor minerals, such as gypsum and clay minerals. Metal concentrations were compared using one-way analysis of variance (ANOVA) to compute the statistical significance of the mean. The results of the ANOVA showed significant differences between sites for Pb, Cd and Cu, but no significant differences for the remaining metals tested. Factor analysis revealed that polluted soil occurs predominantly at sites around the steel plants and that there is no significant variation in the characteristics of the unpolluted soil, which are uniform in the study area.

    The incidence of watermelon chlorotic stunt disease and the molecular characterization of the Jordanian isolate of Watermelon chlorotic stunt virus (WmCSV-[JO]) are described in this study. Symptomatic leaf samples obtained from watermelon (Citrullus lanatus Thunb.), melon (Cucumis melo L.), squash (Cucurbita pepo), cucumber (Cucumis sativus L.), and bottle gourd (Lagenaria siceraria) plants were tested for WmCSV-[JO] infection by PCR. The virus could be detected in 8 melon and 87 watermelon samples obtained from Ghor Assafi (southern part of Jordan Valley). Three samples collected from Mafraq (eastern part of Jordan) were found mixed infected with WmCSV-[JO] and Squash leaf curl virus. The full-length DNA-A and DNA-B genomes of WmCSV-[JO] were amplified, and sequences were deposited in the GenBank under accession numbers EU561237 and EU561236, respectively. Sequence analysis reveals that WmCSV-[JO] is closely related to other virus isolates from Israel (WmCSV-[IL]), Yemen (WmCSV-[YE]), Iran (WmCSV-[IR]), Lebanon (WmCSV-[LB]), and Sudan (WmCSV-[SD]). DNA-A of WmCSV-[JO] showed highest nucleotide identity (99.42%) with WmCSV-[IL], while DNA-B had highest nucleotide identity (95.52%) with WmCSV-[YE]. Data of this study demonstrate that digestion of DNA-B genome of WmCSV isolates with ApaI enzyme can discriminate between these isolates at the molecular level. Infectious clones of WmCSV-[JO] were constructed and agroinoculated to Nicotiana benthamiana plants. Inoculated plants developed mild disease symptoms 4 weeks post inoculation, while watermelon plants biolistically inoculated with WmCSV-[JO] developed characteristic mottling, yellowing and severe leaf curling symptoms 3 weeks post inoculation.

    The combustion metamorphism halo in a bituminous micrite sampled in an adit from the Maqarin site, in northern Jordan (Khoury et al., 1992) was studied by combining different methods (magnetic, thermal, chemical and mineralogical analysis). The magnetic investigations confirmed the existence of a significant magnetic anomaly between the cement bodies and the unaltered sediment. This finding is consistent with previous studies on combustion metamorphism (Cisowski and Fuller, 1987 ; Ron and Kolodny, 1992). The magnetic anomaly observed in Maqarin is found to be double, exhibiting two distinct maxima (for both susceptibility and remanent magnetisation). Combined mineralogical and magnetic characterisations show that the first anomaly is due to magnetite type iron oxides whereas the second anomaly originates from maghemite type oxides and that these ferromagnetic minerals are inherited from sulphide minerals (pyrite). The thermal analysis of the bituminous marl displays two major exothermic events (centered at ~320°C and at ~440°C) and one major endothermic event (centered at ~790°C). These events are correlated with important mass losses. By using the evolved gases analysis (EGA), the two important exothermic events are interpreted as linked to the oxidation of two types of organic matter. The major endothermic event is well known and corresponds to decarbonatation. Using available information and new data acquired during this study, an attempt was done to reconstruct the temperature profile along Maqarin adit at the moment when combustion stopped between unaltered sediments (30 +/- 10 °) and the combusted zone (1100 +/- 50 °C) Cisowski S.

    Background: Alopecia is a common complaint in dermatology clinics, and can be caused by a number of conditions, and has patterns that are different from that seen in adults. Aim of Study: No previous studies investigating the clinical types of hair loss in Jordan and its epidemiology. The ultimate aim was to provide a guide for the evaluation of hair loss commonly occurring in childhood in our environment. Patients and Methods: A total of 2800 children were seen at the dermatology clinics (Karak teaching hospital and Mutah university medical center) during January 2009 to October 2013 complaining of various clinical dermatological symptoms. Results: Of these patients, 210 children were complaining of hair loss and scalp disorders (7.5% of pediatric dermatology cases seen in Jordan). The most common presentation was asymptomatic patchy hair loss (40%). Other symptoms were scaly scalp (22.9%), diffuse hair loss (21.4%), change in hair texture and color (8.1%), pruritus (5.7%), and pain in the scalp (1%). Tinea capitis was the commonest causes of hair loss (40.0%) followed by alopecia areata (26.2%) and telogen effluvium (17.6%). Other common causes of hair loss were observed in this study, these include chronic diffuse form of hair loss, trichotillomania, and traction alopecia. Conclusions: As has been observed in this study, hair problem may be due to important nutritional deficiency such as iron and zinc elements, and this is very important problem to think of especially in developing countries. Therefore, hair examination by a pediatrician or dermatologist is an important part of the physical examination. PMID:24778527

  17. Late ordovician—early silurian glaciofluvial deposits preserved in palaeovalleys in South Jordan

    Periglacial, fluvial strata of Late Ordovician age, infilling incised palaeovalleys in the lower part of the shallow-marine, siliciclastic Khreim Group (Late Ordovician to Silurian) are described from outcrops in south Jordan. The palaeovalley fill predominantly comprises poorly sorted, medium- to coarse-grained, sub-arkose with subordinate beds of pebble- to cobble-size diamictite. Clasts include subangular rip-up sandstone and sparse shelly fossils derived from the local bedrock, together with exotic, rounded pebbles and cobbles derived from the Cambro-Ordovician sandstones and granitoid Precambrian rocks in the palaeohinterland, situated to the south. The palaeovalley fill is locally characterised by synsedimentary slump folds, micro-faulting and contorted bedding. These are attributed either to gravitational slumping at palaeovalley margins, or collapse due to melting of stagnant supporting ice. At some localities, the sandstones are typically trough cross-bedded, and exhibit upward-fining trends terminating in current ripples, suggesting episodic infill of the palaeovalleys. The few palaeocurrent measurements available from these sedimentary structures indicate a general palaeoflow to the north, coincident with the general orientation of the exposed palaeovalleys. The palaeovalleys may have been formed by glacial and/or fluvial processes; their predominantly sandstone fill is interpreted as fluvial and/or glaciofluvial in origin, and was probably deposited as proximal proglacial outwash at some distance from the ice-sheet which lay to the south, in present-day Saudi Arabia. The Batra Mudstone, which overlies coeval, non-channelised, glaciofluvial sandstones yields an Early Llandovery fauna, thus constraining the upper age of the palaeovalley infilling. By analogy with similar strata in Saudi Arabia, erosion of the palaeovalleys and infilling is likely to have taken place during Ashgill to Early Llandovery times. Erosion of the palaeovalleys and their subsequent infilling is associated with the Late Ordovician-Early Silurian glaciation of Gondwanaland, widely reported from central Saudi Arabia and, in the subsurface, from Jordan.

    This study was conducted to evaluate the microbiological quality of sous (a drink prepared by extracting dried roots of Glycyrrhiza glabra) and tamarind (a drink prepared by infusing Tamarindus indica dried pulp), traditional drinks consumed in Jordan. Twenty-one samples of sous and 44 samples of tamarind were collected from the local market in Amman, Jordan. Water is the major component of the drinks. Sous drink is characterized by having an alkaline pH (range, 6.6 to 9.9; mean, 8.6), whereas tamarind drink has an acidic pH (range, 1.8 to 3.7; mean, 2.8). The drinks are not processed for safety before serving, and at some vendors drinks are not properly refrigerated. The mean counts for aerobic bacteria, lactic acid bacteria, and yeasts in sous drink samples were 5.9, 5.0, and 3.8 log CFU/ml, respectively; those in tamarind drink samples were 4.0, <1, and 5.8 log CFU/ml, respectively. The lactic acid bacteria isolated were Enterococcus raffinosus, Enterococcus hirae, Enterococcus durans, Lactobacillus acidophilus, and Lactobacillus buchneri. The yeast isolates in sous drink were from the genera Candida, Filobasidium, Hanseniaspora, Lodderomyces, Pichia, and Williopsis, and those in tamarind drink were from Arthroascus, Brettanomyces, Candida, Debaromyces, Filobasidiella, Hanseniaspora, Klavispora, Lodderomyces, Pichia, Saccharomycodes, Trichosporon, and Zygosaccharomyces. Enterobacteriaceae were detected in two sous samples and were identified as Enterobacter sakazakii and Erwinia sp., and in two tamarind samples and were identified as Citrobacter freundii and Klebsiella pneumoniae. Salmonella was detected in one sous and one tamarind sample. Pseudomonas aeruginosa was detected in only one sous sample. These findings highlight the importance of application of hygienic practices throughout preparation and vending of drinks, starting with raw ingredients and continuing through preparation, storage, display, and serving.

    Biallelic mismatch repair deficiency (bMMRD) is a cancer predisposition syndrome affecting primarily individuals from consanguinous families resulting in multiple childhood cancers including high grade gliomas (HGG). This is the first study to assess the prevalence of bMMRD among patients with HGG in countries where consanguinity is high. We collected molecular and clinical information on all children diagnosed with HGG and supratentorial primitive neuroectodermal tumors (sPNET) between 2003 and 2013 at King Hussein Cancer Center, Jordan. Comparison was made to a similar cohort from Toronto. Clinical data regarding presence of café au lait macules(CAL), family history of cancer, consanguinity, pathology and treatment were collected. Tumors were centrally reviewed and tested for MMRD by immunohistochemistry of the corresponding proteins. Forty-two patients fulfilled the inclusion criteria, including 36 with HGG. MMRD was observed in 39% of HGG of whom79% also lost MMR staining in the corresponding normal cells suggestive of bMMRD. P53 dysfunction was highly enriched in MMR deficient tumors (p?=?0.0003).The frequency of MMRD was significantly lower in Toronto cohort (23%, p?=?0.03). Both evidence of CAL and consanguinity correlated with bMMRD (p?=?0.005 and 0.05,respectively) but family history of cancer didn't. HGG with all three bMMRD risk factors had evidence of MMRD and all children affected by multiple bMMRD related cancers had identical gene loss by immunohistochemical staining. In Jordan, the frequency of clinical and immunohistochemical alterations suggestive of bMMRD in pediatric HGG is high. Genetic testing will enable appropriate counseling and cancer screening to improve survival of these patients. PMID:26293621

    Malaria is considered as one of the most threatening diseases affecting peacekeeping forces serving in malaria endemic countries. The Jordanian Armed Forces participated in many of the United Nations peacekeeping missions in over 20 countries across the world. Thin and thick blood smears were collected from military personnel returning to Jordan, and relevant data including occupation, age, sex, residence address and the country they served in were recorded. Mefloquine 250 mg/week was prescribed for prophylaxis during the period of stay for three contingents of Jordanian military forces deployed to East Timor. Members of two contingents were given post exposure prophylactic treatment of Doxycycline 100 mg coupled with Primaquine 15 mg daily for 14 days soon after returning to Jordan. Blood smears were taken from all soldiers suspected to be affected by malaria, and were monitored over a period of 15 weeks. A total of 811 malaria cases were reported during 1992-2011 among Jordanian military personnel whom served in over 20 countries. Most cases were reported among troops returning from Eretria (54.74%), East Timor (18.86%), Ivory Coast (9.12%) and Sierra Leone (5.1%). Troops aged between 20-40 years constituted 96.3% of the total reported cases. The majority of infections were due to Plasmodium vivax (83.5%), followed by Plasmodium falciparum (13.6%). The attack rates (AR) of malaria/100 soldiers among the three contingents were 10.8% for Timor 1, with no post-exposure prophylaxis, and 2.8% for Timor 2 and 3 with post-exposure prophylaxis. There was an evident reduction of malaria attack rate and relapse rate between the two groups Timor 1 (without post-exposure prophylaxis) and Timor 2 and 3 (given post exposure prophylaxis).

    Objectives The aim of this study was to investigate Jordanian physicians’ perception and attitudes toward generic medicines and generic substitution. It also aimed to examine factors that affect physicians’ pattern of prescribing, and to evaluate their opinion regarding future introduction of Electronic Prescribing (EP) in Jordan. Methods A cross-sectional descriptive study involving Jordanian physicians working in both public and private sectors was undertaken, using a self-administrated anonymous questionnaire. Frequency tables, cross-tabulation and chi square tests were used for data analysis. The response rate was 75.2% (n = 376/500). Results Cost was claimed to be an important factor in the prescribing decision for 69.1% of the Jordanian physicians. The majority of physicians (77.4%) claimed that they often prescribe generic medicines. Jordanian physicians predominantly welcomed the implementation of an EP and International Nonproprietary Name (INN) prescribing systems with 92%, and 80.1% respectively. More than two thirds of the physicians (69.4%) accepted generic substitution by pharmacists, with a significant association with their employment sector; physicians who work in the private sector tended to oppose generic substitution compared with physicians who work in the public sector. Physicians mostly (72.1%) opposed that generic substitution should only be allowed upon patient request. Conclusions Jordanian physicians have a positive attitude towards generic medications and high willingness and acceptance of strategies that encourage generic utilisation such as EP, INN prescribing and generic substitution. All these strategies would help reduce the high expenditure on medicines in Jordan. These findings would provide baseline data to policy makers to develop a robust generic policy to achieve greater clinical effectiveness and economic efficiency from medicines prescribing.

  2. Quantifying sediment connectivity in Wadi Al-Arab (NW Jordan) using a sediment budget approach

    Due to data scarcity, sediment connectivity most often only qualitatively describes the potential transfer of sediments through a landscape. However, quantitative information on sediment delivery is of special relevance for modelling approaches as well as for sustainable land and water management, especially in water scarce regions such as Jordan, where valuable water reservoirs suffer from sediment pollution. Measurements are needed to quantify sediment outputs of the different land units and to trace their pathways though the catchments. This study uses the outcomes of a multiple response sediment budget approach conducted in the Wadi al-Arab catchment in northwest Jordan (263.5 km²) to quantify sediment connectivity. The catchment shows a Mediterranean to semi arid climate and consists of carbonatic and marly geology of the Upper Cretaceous. The topography ranges from rolling hills in the East to steeper mountainous areas in the North and West were olive orchards are the main agricultural use. Soil erosion measurements in the main land use units and relevant sediment sources, such as olive orchards, agricultural fields, and natural vegetated slopes uncovered the potential ranges of soil erosion rates in these units. Furthermore, the annual sediment yield in the Wadi Al Arab water reservoir was calculated. With the extrapolation of the erosion rates of the main contributing land use units and the annual sediment amount that reaches the sink, a maximum value of lateral sediment connectivity could be quantified, reaching up to 18%. A multiple sediment fingerprint method was used to delineate the relative contribution of each measured source to the sink based on the lake sediment samples. Supported by additional 137Cs analysis of terrace samples and a survey of the Wadi bed a high longitudinal connectivity could be derived. The applied method mix allowed the quantification of lateral sediment connectivity on catchment scale and gave a comprehensive understanding of the longitudinal connectivity in the Wadi bed, this way serving as possible data base to test available sediment connectivity models.

    The closed basin of the Lower Jordan Valley with the Dead Sea as final sink features high evapotranspiration rates and almost complete reuse of treated wastewater for irrigation farming. This study focuses on the water transfer schemes and the presence, spreading, and potential accumulation of pharmaceutical residues in the local water resources based on findings of a five-year monitoring program. Overall 16 pharmaceuticals and 9 iodinated X-ray contrast media were monitored in groundwater, surface water, and treated wastewater. A total of 95 samples were taken to cover all geographical settings and flow paths from origin (wastewater) to target (groundwater). Nine substances were detected in groundwater, with concentrations ranging between 11 ng/L and 33,000 ng/L. Sometimes, detection rates were higher than in comparable studies: Diatrizoic acid 75%, iopamidol 42%, iopromide 19%, iomeprol 11%, carbamazepine and iohexol 8%, ibuprofen 6%, and fenofibrate and iothalamic acid 3%. Concentrations in groundwater generally increase from north to south depending on the application of treated wastewater for irrigation. Almost all substances occurred most frequently and with highest concentrations in treated wastewater, followed by surface water and groundwater. As exception, diatrizoic acid was found more frequently in groundwater than in treated wastewater, with concentrations being similar. This indicates the persistence of diatrizoic acid with long residence times in local groundwater systems, but may also reflect changing prescription patterns, which would be in accordance with increasing iopamidol findings and surveys at local hospitals. Trend analyses confirm this finding and indicate a high probability of increasing iopamidol concentrations, while other substances did not reveal any trends. However, no proof of evaporative enrichment could be found. The high spatial and temporal variability of the concentrations measured calls for further systematic studies to assess the long-term evolution of organic trace substances in this reuse setting.

    No indications are available for the existence of above-boiling geothermal systems in the Jordan Rift Valley. Slightly higher than observed temperatures are concluded for a deep component at the springs of Hammat Gader (67°C), Gofra (68°C), the Russian Garden (40°C), and the Yesha well (53–65°C). These temperatures may encourage further developments for spas and bathing installations and, to a limited extent, for space heating, but are not favorable for geothermal power generation.

  7. Ozone Levels in the North and South of Jordan: Effects of Transboundary Air Pollution

    NASA Astrophysics Data System (ADS)

    Alsawair, Jihad Khalaf

    The first phase of this work sought to assess the causes of air quality deterioration in the south of the region over the Red Sea near the resort areas of Eilat and Aqaba. Accordingly, a coordinated Jordanian-Israeli study was performed during the month of November 2007 along the boarder of the two countries. The Jordanian measurements were made at a fixed monitoring location in the city of Aqaba, while the Israeli measurements were made using a mobile laboratory at kibbutz Eilot some 3 km north of the coastal city of Eilat. The results indicated that pollution episodes are highly dependent on wind direction, where southerly winds carry local transportation (i.e., ship, trucks) and possibly some industrial emissions towards the north end of the Red Sea, while northerly winds are associated with the transport of regional O 3. The results revealed that under the prevailing (˜90% of the time) northerly wind flows, the quality of the air is relatively good for all primary pollutants but O3 was elevated, indicative of the downwind regional transport of this secondary species from the Mediterranean coast. However, during days with southerly air flow the air quality was significantly deteriorated with elevated levels of sulfur dioxide (SO2) and nitrogen oxides (NOx). The second phase of this work, which also involved Jordanian and Israeli scientists, was undertaken in the northern part of the region for a two-week period in May/June 2009. This part of the research was aimed at examining previous modeling results that indicated that elevated O3 levels should occur in Northern Jordan from emissions in Northern Israel that are transported a distance of more than 100 km. Ozone and other pollutants were monitored at five sites in Israel (Haifa, Neve Shanan, Kiryat Tivon, Afula, and Maoz Haim) and two in Jordan (Taiba and Irbid). The sites were located along the prevailing wind direction that presumably moves air-masses eastward from the Mediterranean coast, over the Israel Valley toward the Jordan Valley, and then into Northern Jordan. Results confirmed the previous modeling results, suggesting that peak O3 values are observed at later hours as a function of distance from the Mediterranean coast and that maximum O 3 levels are found over northern Jordan. Based on the findings of the first phase that showed elevated O 3 and NOx levels over the Gulf of Aqaba, more investigation was required to assess air quality in the city of Aqaba. Accordingly, long term air quality monitoring study conducted by Jordanian scientists was undertaken during the years 2008-2009. The study was conducted using a fixed air quality station located in the city. Results of this study indicated that topography of the city, with mountains surrounding the city from the east, played a major role in the air masses recirculation and hence the transport of primary pollutants, including NOx from the southern industrial area and the transportation emissions into the northern part of the city. However, high O3 episodes were found to be associated with northern wind in the absence of air masses recirculation indicating the role of long range transport in causing these elevated levels. Thus, based on the results of these studies and in order to reduce the potential health impacts of O3 and its precursors in downwind areas, strategies to control these pollutants should be developed. These strategies should be based on better energy, traffic and industrial management since these are the three main pollution sources. The strategies should include more efficient use of raw materials and energy, better combustion and production technologies that utilize less fuel and emit less pollutant. Measures should include controlling precursors' emissions at the sources located along the east Mediterranean coast, mainly power generation facilities, oil refineries, ports activities, and traffic. In addition, local emissions in the region such as emissions in the Gulf of Aqaba should be reduced by adopting strategies that include the use of cleaner fuel (industry, ships, and vehicles), enforcing the national emission standards, and the use of air pollution control devices. Such strategies would not be accomplished without a regional and continental cooperation. (Abstract shortened by UMI.)

  8. Anthropogenic Influence On Groundwater Quality In Jericho and And Adjoining Wadis (Lower Jordan Valley, Palestine)

    The Lower Jordan Valley is part of the Jordan-Dead Sea Rift. The graben is filled by sedmiments of limnological and marine origin. Towards the Dead Sea, the occurance of gipseous and salty sediments on the valley floor increase. The southern part of the Lower Jordan Valley, where the city of Jericho is situated, is an arid area (<150 mm precipitation/year), with less amount of exploitable fresh groundwater or surface water. Jericho was founded on an alluvial fan, closely to the western mountain range in front of mouth of Wadi Qilt. The fan serves as reservoir for infiltrating water from wadi runoff and groundwater from the crataceous aquifers of the western shoulder. The fan is surrounded by unsuitable aquifers of the graben, which are filled with saline water. The aim of this study, which takes place inside the multilateral SMART-project, is to understand the vulnerability of the Jericho groundwater aquifers in connection with lowering the groundwater table by overexploitation and the intensively use of pesticides Jericho and its vicinity are of most importance for the Palestinians. However, beside the about 25,000 residents, the tourism industry and the vital agriculture depend on sufficient and expoitable fresh water resources. Because the demand of water is increasing, overexpoitaion takes place. Due to over extraction of groundwater a huge depression cone is evolving during the dry season which is filled up again according to the groundwater recharge in the rainy season. Concomitantly, depression cone in the fresh water aquifers leads to an infiltration of the surrounding saltwater. The amount of saltwater which infiltrates into the freshwater resource was calculated by different stable isotope methods (d2H, d18O) and hydrochemical analyses of wellwater. The agriculture is main consumer of groundwater - over 60% of the pumped water is used for inefficient irrigation. Additionally, an intensive use of pesticides in concentrated liquid and gaseous forms for vegetable gardening hold the danger to pollute the groundwater via irrigation return flow. This return flow most probably endangers the quality of the water resource, because shallow wells nearby extract it directly from the underground. However, one result of the first screening campaign concerning pesticide remnants in the groundwater wells of Jericho, just traces have been detected. Thus, the higher amount of chemicals is retained by the soil during infiltration of irrigated water. The detected low concentrations in groundwater of the fan may be the result of outleaching from agricultural areas from the mountain range. The flood water of Wadi Qilt infiltrates partly in the fluviatil sediments. The ongoing investigations in the Wadi Qilt-Jericho area include an approach of combined hydrochemical and hydraulic studies to simulate the complex groundwater system at the edge of the graben and to prepare a sustainable groundwater management strategy for the area of Jericho.

    Background Most studies report that being parents of a child with cancer is a stressful experience, but these have tended to focus on mothers and few have included both parents. Moreover, studies have focussed on families in Western countries and none have been published examining the psychological outcomes for parents living in an Arabic country. This research explores the stress levels of Jordanian parents caring for a child with cancer in order to identify the psychological needs of parents in this environment and to explore how mothers and fathers stress levels might differ. Methods The study was carried out in Jordan using the Perceived Stress Scale 10-items (PSS10). The questionnaire was completed by 300 couples with a child who has cancer and a comparison group of 528 couples where the children do not have any serious illness. Multivariate backward regression analysis was carried out. Results Analysis adjusting for spousal stress and sociodemographic predictors revealed that stress levels of mothers with a child who had cancer remained significantly higher than mothers whose children did not have any serious illness (p?Jordan.

    In regard to the quantitative and qualitative water problems in Jordan the soil layer and its physical integrity is important to slow down runoff, guarantee infiltration, and a sensible parameter in terms of hydrologic modeling. Erosion harms this potential and needs to be better understood and quantified in the region. Therefore, a multiple response approach was implemented to compile a sediment budget for the research area Wadi Al-Arab in the NW of Jordan (263,5km2). The climate is Mediterranean to semi-arid with <300 to 550mm of rain in winter. Mainly marl and limestone of the Upper Cretaceous and the Paleocene make up the catchment's geology. The area is characterized by an agricultural basin in the east and an increase in relief energy to the west and south. Different field measurements were implemented on relevant sediment sources, such as olive orchards, agricultural fields, natural vegetated slopes and exposed rock with patchy vegetation as well as the Wadi Al Arab Dam Lake as the final sink. The focus involved the quantification of the yearly sediment yields and the deposition in the lake, respectively. In a second step a multiple sediment fingerprint was applied including the geochemical differentiation of the sources with inorganic elements and radio nuclides. The relative importance of each source could be calculated on the basis of lake sediment samples. Results of these two approaches cover different spatial scales and only partly integrate the transport way. Hence, they cannot be directly compared but consider the problem from different perspectives and are used in the final step to calibrate and validate the setup of the SedNet model (Wilkinson et al. 2008) for the catchment. The model offers the possibility to incorporate additional raster information, includes additional sources such as gully and bank erosion, and takes account for different areas of deposition according to the measured and regionalized discharge in the region. Its' implementation helped to test the field findings to their limits and provides a more holistic sediment budget for Wadi Al-Arab. Reference: Wilkinson, S., Henderson, A., Chen, Y., Sherman, B.

    The Mississippi, Minnesota, and St. Croix Rivers greatly influence flow patterns in the Prairie du Chien-Jordan aquifer. Water generally flows toward these streams from surrounding water-level highs. Heavy pumping has caused only localized cones of depression. In contrast, pumping in Minneapolis and St. Paul has greatly influenced ground-water flow in the Mount Simon-Hinckley aquifer, resulting in a large cone of depression. Between 1971 and 1980 average water levels in the Prairie du Chien-Jordan aquifer changed less than 5 feet in most of the study area, while average water levels in the Mount Simon-Hinckley aquifer rose as much as 60 feet in the center of the cone of depression. Water-level data suggest that (1) little variation of annual pumpage between 1971 and 1980 from the Prairie du Chien-Jordan aquifer produced generally stable water levels in that aquifer, (2) decreased annual pumpage from 1971 to 1980 from the Mount Simon-Hinckley aquifer caused rising water levels in that aquifer, and (3) a greater seasonal component of pumpage for the Mount Simon-Hinckley aquifer than for the Prairie du Chien-Jordan produced larger and more widespread seasonal water-level declines in the Mount Simon-Hinckley than in the Prairie du Chien-Jordan, particularly during dry years.

    In 1967 the Group of Sculptures was discovered in Petra during clearance works organized by the Department of Antiquities in Jordan in the Temenos of Qasr el Bint around the Temenos Gate. One of these sculptures was a high relief statue of a female sphinx. Due to the paucity of information about this statue, this paper has been written to answer a number of questions: What was its original site or monument? When was it made? Who was the deity or deities it represented? Could there be another interpretation of its existence? The answers to the above provide enlightenment of Nabataean styles of carvings and an insight into their religious thoughts. Rgarding the interpretation of the Female Sphinx. Three ideas have been suggested. First, it can be the main Nabataean goddess Allat, "the mother of the gods". Second, it is an image of Petra as a goddess. Third, it is carved on the Temenos Gate as a guardian of Petra city in general and its holy monuments like temples and tombs in particular.

    Nabataean pottery is distinguished by the thinness of its walls, which were sometimes only 1.5 mm thick. It was a pinkish/red color, often decorated by hand with dark brown flower and leaf designs. The typical (egg-shell) shallow open bowls productions were very difficult to make on the potter's wheel, demonstrating how skilled their craftsmen were Nabataean painted pottery from Petra Jordan were examined in order to determine the mineralogical characteristics of the raw pigment materials used for their production and to elucidate the ceramic manufacturing technologies employed. Optical microscopy, X-ray diffraction analysis (XRD) and scanning electron microscopy (SEM-EDS) were the analytical techniques used. The initial examination of the ceramic shreds in optical microscopy showed all samples to be identical in their paint and paste textures. The mineralogical composition of the paste (unpainted outer surface) is typical of a clay poor in calcium and fired at moderate-high temperature in an oxidizing atmosphere. The paste is composed of quartz, plagioclase, potassium feldspar, hematite, dolomite, and calcite. The latter two phases might be attributed to post-depositional contamination, since examination with both optical and scanning electron microscopes show fine carbonate particles deposited in the pores and cracks of the shred. The paint on the inner surface of the vessel, on the other hand is composed of hematite as a major phase with only some quartz and plagioclase.

    Moral distress has received much attention in international nursing published work in recent years. However, in the published work, little is known about the moral distress of mental health nurses. The aims of this study were to examine the intensity level of moral distress, to identify the best predictors of moral distress, and to examine relationships of moral distress with burnout, job satisfaction, intention to leave the current job, and both demographic and work-related variables of that group. Employing a descriptive correlational cross-section design and a convenience sampling method, data were collected using the Moral Distress Scale for Psychiatric Nurses, Maslach Burnout Inventory, and Job Satisfaction Scale from 130 Jordanian mental health nurses working in the largest psychiatric hospital in Jordan. Results showed that the intensity level of moral distress was found to be moderately high, especially in an 'unethical conduct by caregivers' subscale. Age, income level, nurses' years of experience, and caseloads correlated significantly and negatively with moral distress, while educational level and intention to leave the current job correlated significantly and positively with moral distress. Interestingly, job satisfaction did not significantly correlate with moral distress. Income level, caseloads, burnout level, attending workshops in mental health, and educational level were the best predictors of moral distress. More studies on moral distress and continuing educational interventional programs aimed at minimizing the levels of moral distress and burnout at institutional and individual level are required.

    The Al-Hisa Phosphorite Formation (AHP) in the Eshidiyya basin of south Jordan consists of three members, the lower member accommodates the main high grade commercial phosphorite deposits, followed upwards by the coquinoidal limestone member which is overlain by the uppermost member, the A0 member. The phosphorites in both member are granular (peloidal) type deposits. Uranium (U) and Vanadium (V), in the main phosphorites of the lower member, are 75 and 70 ppm respectively as analyzed in a previous work. The distribution of the analyzed elements in this work is governed by three factors: the phosphorite (P, Ca, Na, U, V, Cd, Zn, and Sr) decreasing upwards from the lower A0 unit to the topsoil, detritals (Al, Si, Fe, Mg, K, Ga, Hf, Nb, Rb, Th, and Zr) increasing upwards, and minor carbonates (Ca, and Sr) with no obvious trend. Uranium is three times more enriched in the upper phosphorite member, the A0, relative to the lower or main phosphorite member, 234 ppm versus 75 ppm respectively. Vanadium is likewise enriched several times in the A0. Both elements, U and V are worth further exploration in the A0 in northern Eshidiyya basin. Thorium, Zr and Hf are relatively low.

    The aim of the current study was to determine the most prevalent sources of stress among first-year nursing students at a military college in Jordan. A descriptive cross-sectional study was performed using a convenience sample of 138 students (females between ages 18 and 22). The Student Stress Survey was used to identify stressors and assess their relative importance. The instrument consists of 40 items divided into four categories of potential sources of stress: (a) intrapersonal, (b) interpersonal, (c) academic, and (d) environmental. Data were analyzed using descriptive statistics. The top five sources of stress reported were: increased class workload (89%), change in living environment (83%), change in social activities (78%), change in eating habits (77.5 %), and change in sleeping habits (76%), with academic sources of stress being the most frequently reported. The results provide valuable information for educators and administrators in nursing colleges to identify types of stress among first-year nursing students and establish strategies to reduce stress among such students, particularly from academic and environmental sources.

    In paleomagnetism, periods of high field intensity have been largely ignored in favor of the more spectacular directional changes associated with low field intensity periods of excursions and reversals. Hence, questions such as how strong the field can get and how fast changes occur are still open. In this paper we report on data obtained from an archaeometallurgical excavation in the Middle East, designed specifically for archaeomagnetic sampling. We measured 342 specimens from 72 samples collected from a 6.1 m mound of well stratified copper production debris at the early Iron Age (12th-9th centuries BCE) site of Khirbat en-Nahas in Southern Jordan. Seventeen samples spanning 200 yr yielded excellent archaeointensity results that demonstrate rapid changes in field intensity in a period of overall high field values. The results display a remarkable spike in field strength, with sample mean values of over 120 ?T (compared to the current field strength of 44 ?T). A suite of 13 radiocarbon dates intimately associated with our samples, tight control of sample location and relative stratigraphy provide tight constraints on the rate and magnitude of changes in archaeomagnetic field intensities.

    Hashemite, Ba(Cr,S)O4, the isostructural chromate analogue of baryte, has been found in west-central Jordan. It is associated with chromian ettringite, apatite and calcite in a phosphatic carbonate rock analogous to the Hatrurim formation in Israel. The mineral is orthorhombic, Pnma, with a 9.112(2), b 5.541(1), c 7.343(1) A, Z = 4. Strongest XRD lines are 3.516(100), 3.171(80), 3.669(60), 2.175(60), 2.150(45) A. Hashemite occurs as small, euhedral, dark brown, commonly zoned crystals with an average D 4.59 g/cm3 and H. 31/2. It is biaxial positive; dark varieties have alpha 1.952(2), beta 1.960(2), gamma 1.977(2); light varieties have alpha 1.810(2), beta 1.813(2), gamma 1.824(2), 2Vgamma 35o-57o.-J.A.Z.

    Recent excavations and high-precision radiocarbon dating from the largest Iron Age (IA, ca. 1200–500 BCE) copper production center in the southern Levant demonstrate major smelting activities in the region of biblical Edom (southern Jordan) during the 10th and 9th centuries BCE. Stratified radiocarbon samples and artifacts were recorded with precise digital surveying tools linked to a geographic information system developed to control on-site spatial analyses of archaeological finds and model data with innovative visualization tools. The new radiocarbon dates push back by 2 centuries the accepted IA chronology of Edom. Data from Khirbat en-Nahas, and the nearby site of Rujm Hamra Ifdan, demonstrate the centrality of industrial-scale metal production during those centuries traditionally linked closely to political events in Edom's 10th century BCE neighbor ancient Israel. Consequently, the rise of IA Edom is linked to the power vacuum created by the collapse of Late Bronze Age (LB, ca. 1300 BCE) civilizations and the disintegration of the LB Cypriot copper monopoly that dominated the eastern Mediterranean. The methodologies applied to the historical IA archaeology of the Levant have implications for other parts of the world where sacred and historical texts interface with the material record.

    New human burials from northern Jordan provide important insights into the appearance of cemeteries and the nature of human-animal relationships within mortuary contexts during the Epipalaeolithic period (c. 23,000–11,600 cal BP) in the Levant, reinforcing a socio-ideological relationship that goes beyond predator-prey. Previous work suggests that archaeological features indicative of social complexity occur suddenly during the latest Epipalaeolithic phase, the Natufian (c. 14,500–11,600 cal BP). These features include sedentism, cemeteries, architecture, food production, including animal domestication, and burials with elaborate mortuary treatments. Our findings from the pre-Natufian (Middle Epipalaeolithic) cemetery of ‘Uyun al-Hammam demonstrate that joint human-animal mortuary practices appear earlier in the Epipalaeolithic. We describe the earliest human-fox burial in the Near East, where the remains of dogs have been found associated with human burials at a number of Natufian sites. This is the first time that a fox has been documented in association with human interments pre-dating the Natufian and with a particular suite of grave goods. Analysis of the human and animal bones and their associated artefacts provides critical data on the nature and timing of these newly-developing relationships between people and animals prior to the appearance of domesticated dogs in the Natufian.

    This communication presents the results of an active thermography survey of the Silk Tomb, which belongs to the Royal Tombs compound in the archaeological city of Petra in Jordan. The Silk Tomb is carved in the variegated Palaeozoic Umm Ishrin sandstone and it is heavily backweathered due to surface runoff from the top of the cliff where it is carved. Moreover, the name "Silk Tomb" was given because of the colourful display of the variegated sandstone due to backweathering. A series of infrared images were taken as the façade was heated by sunlight to perform a Principal Component of Thermography analyses with IR view 1.7.5 software. This was related to indirect moisture measurements (percentage of Wood Moisture Equivalent) taken across the façade, by means of a Protimeter portable moisture meter. Results show how moisture retention is deeply controlled by lithological differences across the façade.

    We examined within- and between-person variations in parental legitimacy beliefs in a sample of 883 Arab refugee youth (Mage = 15.01 years, SD = 1.60), 277 Iraqis, 275 Syrians, and 331 Palestinians, in Amman, Jordan. Latent profile analyses of 22 belief items yielded 4 profiles of youth. The normative profile (67% of the sample, n = 585) most strongly endorsed parental authority legitimacy for prudential (risky) items, followed by moral, conventional, and then friendship items, with legitimacy lowest for personal items. The low-normative profile (10%, n = 85) followed a similar pattern, although legitimacy ratings were significantly lower than normative youth for most items, but not the personal ones. Rebellious youth (11%, n = 96) held deviant peer values; they endorsed less legitimacy, particularly for prudential and friendship items, than did youth in other profiles. Mixed youth (12%, n = 101) were similar to rebellious youth in some judgments and ryouth in others. Profile membership did not differ by adolescents' age or parental socioeconomic status but did differ by gender and national background. Youth fitting the normative (and to some extent, the low-normative) profile rated parents higher in support, behavioral control, and knowledge of adolescents' activities and lower in psychological control-disrespect and harsh punishment than did rebellious or mixed youth. Normative (and also, but less consistently, low-normative) youth reported better psychosocial adjustment across multiple measures than did rebellious and mixed youth.

    Thirty one soil samples were collected from south Jordan around the cement factory in Qadissiya area. The samples were obtained at two depths, 0-10 cm and 10-20 cm and were analyzed by atomic absorption spectrophotometery for Pb, Zn, Cd, Fe, Cu and Cr. Physicochemical factors believed to affect their mobility of metals in soil of the study area were examined such as; pH, TOM, CaCO3, CEC and conductivity. The relatively high concentrations of lead, zinc and cadmium in the soil samples of the investigated area were related to anthropogenic sources such as cement industry, agriculture activities and traffic emissions. It was found that the lead, zinc and cadmium have the highest level in area close to the cement factory, while the concentration of chromium was low. This study indicate that all of the metals are concentrated on the surface soil, and decreased in the lower part of the soil, this due to reflects their mobility and physical properties of soil and its alkaline pH values. The use of factor analysis showed that anthropogenic activities seem to be the responsible source of pollution for metals in urban soils. PMID:16361028

    Recent excavations at Pre-Pottery Neolithic A (PPNA) WF16 in southern Jordan have revealed remarkable evidence of architectural developments in the early Neolithic. This sheds light on both special purpose structures and “domestic” settlement, allowing fresh insights into the development of increasingly sedentary communities and the social systems they supported. The development of sedentary communities is a central part of the Neolithic process in Southwest Asia. Architecture and ideas of homes and households have been important to the debate, although there has also been considerable discussion on the role of communal buildings and the organization of early sedentarizing communities since the discovery of the tower at Jericho. Recently, the focus has been on either northern Levantine PPNA sites, such as Jerf el Ahmar, or the emergence of ritual buildings in the Pre-Pottery Neolithic B of the southern Levant. Much of the debate revolves around a division between what is interpreted as domestic space, contrasted with “special purpose” buildings. Our recent evidence allows a fresh examination of the nature of early Neolithic communities. PMID:21536900

    The Dead Sea area is increasingly facing serious subsidence and sinkhole hazards. On March 22, 2000, the dyke of a two-month old major salt evaporation pond, located along the shore of the Lisan Peninsula (Jordan), collapsed over almost two kilometers. The pond was set up over unstable new lands that have been progressively emerging during the last three decades. In one hour, 56 millions m3 of brine poured out into the northern, natural part of the Sea. Here, we present data suggesting that the drop of the water level, in conjunction with the particular tectonic setting of this area, is at least one of the factors that led to the disaster. We focused our study over the northern part of the Lisan Peninsula and Ghor Al Haditha which are two places undergoing the most intense deformations along the Jordanian Dead Sea coast. We used the results of a static high precision gravimetric survey to detect subsurface cavities in Ghor Al Haditha. We analyzed a interferometric digital terrain model of the recent emerged platform of the Lisan peninsula and interpreted radar differential interferograms contemporary with gravity measurements for the peninsula. We discuss the possibilities to detect, assess and monitor areas prone to collapse on the Jordanian side of the southern Dead Sea coast.

    Coarse (>2.2 ?m) and fine (<2.2 ?m) atmospheric particulate material samples were collected from an urban area (Al-Hashimya, Jordan), from August 2000 to August 2001 using a "GENT" stack filter unit (SFU). Collected samples were analyzed for 19 elements using inductively coupled plasma mass spectrometry (ICP-MS). The crustal elements exhibit atmospheric concentrations that are comparable to those in urban and industrial areas. The anthropogenic elements, on the other hand, are clearly less abundant in Al-Hashimya than in other industrial regions. Results indicated that, elements of crustal origin are associated with the coarse particles, while elements of anthropogenic origins are more associated with fine particles. Concentrations of crustal-derived elements were higher in summer and those of anthropogenic elements were higher in winter. Crustal enrichment factor calculations showed that concentrations of Pb, Zn, Cd, Sb and Ag are highly enriched and of As, Cu, Co, Ca and Ni are moderately enriched. Factor analysis calculations permitted the identification of four source groups for the fine fraction, namely oil combustion, crustal and urban dust, smelting industries and motor vehicles.

    Postoperative pain management is nowadays considered an integral part of modern surgical practice. An audit was made in 2010 to assess the status of acute postoperative pain management at Jordan University Hospital. Data were collected from patients' files and through face-to-face interviews of all patients aged over 16 years who underwent general, gynaecological, ear-nose-throat and orthopaedic surgery. Of 275 patients, 72.0% experienced moderate to severe pain postoperatively at rest and 89.3% on movement. No analgesics were prescribed to 4.7% of the patients and of the remainder, a single analgesic was prescribed to 51.5%. Pethidine and paracetamol were the drugs most commonly prescribed (to 66.9% and 42.5% of patients respectively), most often on a regular schedule rather than on-demand. Despite improvements in pain management worldwide, patients at this hospital were still suffering from postoperative pain. Awareness among professionals and the public is needed and a structured acute pain management programme is essential. PMID:24617129

    Although texts and wall paintings suggest that bees were kept in the Ancient Near East for the production of precious wax and honey, archaeological evidence for beekeeping has never been found. The Biblical term “honey” commonly was interpreted as the sweet product of fruits, such as dates and figs. The recent discovery of unfired clay cylinders similar to traditional hives still used in the Near East at the site of Tel Reov in the Jordan valley in northern Israel suggests that a large-scale apiary was located inside the town, dating to the 10th–early 9th centuries B.C.E. This paper reports the discovery of remains of honeybee workers, drones, pupae, and larvae inside these hives. The exceptional preservation of these remains provides unequivocal identification of the clay cylinders as the most ancient beehives yet found. Morphometric analyses indicate that these bees differ from the local subspecies Apis mellifera syriaca and from all subspecies other than A. m. anatoliaca, which presently resides in parts of Turkey. This finding suggests either that the Western honeybee subspecies distribution has undergone rapid change during the last 3,000 years or that the ancient inhabitants of Tel Reov imported bees superior to the local bees in terms of their milder temper and improved honey yield.

    Two known low-temperature areas (Warm Springs fault and Crystal Hot Springs) are located in the Jordan Valley, but the primary purpose of this report is to locate other low-temperature resources not previously identified. Geothermal reconnaissance techniques utilized in this study include a temperature survey and chemical analysis of wells and springs, and temperature-depth measurements in holes of opportunity. Also, further site specific gravity modelling for the Warm Springs fault geothermal area and initial modelling for the entire valley were also conducted. Areas identified as having potential low-temperature geothermal resources at depth are: (1) the north-central valley area; (2) an east-west portion of the central valley; and (3) a north-south oriented area extending from Draper to Midvale. Each of these areas exhibits ground-water temperatures 20/sup 0/C or greater. Each area has thermal wells with common ion characteristics similar to both Crystal Hot Springs and the Warm Springs fault geothermal systems. Significant concentrations of Sr, Li, B, and F are present in many of these wells.

    Ten thousand years before Neolithic farmers settled in permanent villages, hunter-gatherer groups of the Epipalaeolithic period (c. 22–11,600 cal BP) inhabited much of southwest Asia. The latest Epipalaeolithic phase (Natufian) is well-known for the appearance of stone-built houses, complex site organization, a sedentary lifestyle and social complexity—precursors for a Neolithic way of life. In contrast, pre-Natufian sites are much less well known and generally considered as campsites for small groups of seasonally-mobile hunter-gatherers. Work at the Early and Middle Epipalaeolithic aggregation site of Kharaneh IV in eastern Jordan highlights that some of these earlier sites were large aggregation base camps not unlike those of the Natufian and contributes to ongoing debates on their duration of occupation. Here we discuss the excavation of two 20,000-year-old hut structures at Kharaneh IV that pre-date the renowned stone houses of the Natufian. Exceptionally dense and extensive occupational deposits exhibit repeated habitation over prolonged periods, and contain structural remains associated with exotic and potentially symbolic caches of objects (shell, red ochre, and burnt horn cores) that indicate substantial settlement of the site pre-dating the Natufian and outside of the Natufian homeland as currently understood.

This discovery is the first formal and southernmost record of these marine gobies from the waters of subtropical Taiwan. The new species, Clariger taiwanensis sp. n., is distinguished from its congeners by a unique combination of features: (1) fin rays: dorsal-fin rays III, I/8; anal-fin rays modally I/8; and pectoral-fin rays modally 19 (2+16+1); (2) longitudinal dermal ridge on head with 6 barbels; and (3) specific coloration pattern: head and trunk dark brown with scattered pale spots and blotches; cheek, ventral portion of head sometimes pale with deep brown spots; pectoral-fin base with a dark brown band; and caudal fin mostly dark brown proximally and with alternating and irregular dark brown and pale bands distally. A diagnostic key to all nominal species from Japan and Taiwan is provided. PMID:22711994

    More than 100 underground water wells drilled in Jordan are known to have brackish water with total desolved solids (TDS) over 1500 ppm but not greater than 4000 ppm. The world standard for potable water limits the TDS count to 500 ppm in addition to being free from live microorganisms or dangerous mineral and organic substances. A reverse osmosis desalination scheme powered by a stand-alone wind energy converter (WEC) is proposed to produce fresh water water from wells located in potentially high-wind sites. The purpose of this study if to present the main design parameters and economic estimates of a wind-assisted RO system using a diesel engine as the baseline energy source and an electric wind turbine for the wind energy source. It is found that brackish water pumping and desalinating using WECs costs 0.67 to 1.16 JD/m[sup 3] (JD = Jordanian Dinar, 1US$ = 0.68 JD), which is less than using conventional diesel engines especially in remote areas. In addition, the wind-reverse osmosis system becomes more economically feasible for higher annual production rates or in good wind regimes.

    Stigma is a fundamental barrier to seeking and engaging in mental health treatment for individuals managing depression. This study examines stigma perceptions of mental health treatment for Arab adolescents managing depression using a vignette survey completed by adults in public spaces in Amman, Jordan (n = 108). The vignette was systematically changed across four different conditions that varied the described youth's gender and whether or not they were receiving treatment for their depression. Two-way ANOVAs found that gender and receipt of mental health treatment influenced perceptions of stigma. Seeking treatment, however, did not increase perceived stigma, and receiving mental health treatment rather than no treatment was found as more likely to be a helpful approach for both males and females. Findings indicate that personal level stigma may have greater effects on females whereas public stigma may exert more influence on males. Participants endorsed that adolescents with depression are most likely to be helped when a family sought treatment rather than not seeking treatment. Findings also indicate that the community seems to appreciate the need for treatment and the likelihood of benefiting from formal mental health services. PMID:25027014

    Over the last two decades, Jordan has suffered a chronic water crisis, and is the tenth most water-scarce nation on Earth. Such water stress has been well illustrated in the case of Greater Amman, the capital, which has grown dramatically from a population of around 2000 in the 1920s, to 2.17 million today. One of the distinctive characteristics of the water supply regime of Greater Amman is that since 1987 it has been based on a system of rationing, with households receiving water once a week for various durations. Amman is highly polarized socio-economically, and by means of household surveys, both quantitative and qualitative, conducted in high- and low-income divisions of the city, a detailed empirical evaluation of the storage and use of water, the strategies used by households to manage water and overall satisfaction with water supply issues is provided in this paper, looking specifically at issues of social equity. The analysis demonstrates the social and economic costs of water rationing and consequent management to be high, as well as emphasizing that issues of water quality are of central importance to all consumers regardless of their socio-economic status within the city.

Seroprevalence estimates indicated that 18.1% (95% CI: 11-25.3) of cattle herds and 34.3% (95% CI: 28.4-40.4) of small ruminant flocks were seropositive. The results showed that 100% of the interviewed livestock keepers were aware of brucellosis: 87% indicated a high risk of infection if unpasteurized milk is consumed and 75% indicated a high risk if unpasteurized dairy products are consumed. Awareness of the risk of infection through direct contact with fetal membranes or via physical contact with infected livestock is considerably lower, 19% and 13%, respectively. These knowledge gaps manifest in a high frequency of high-risk practices such as assisting in animal parturition (62%), disposing aborted fetuses without protective gloves (71.2%) or masks (65%), and not boiling milk before preparation of dairy products (60%). When brucellosis is suspected, basic hygiene practices are often disregarded and suspect animals are freely traded. Public health education should be enhanced as the disease is likely to remain endemic in the ruminant reservoir as long as a suitable compensation program is not established and trust on available vaccines is regained.

    SETTING According to anecdotal evidence, waterpipe smoking may lead to the initiation of cigarette smoking among young people. This hypothesis is yet to be examined using an appropriate study design and a theoretical model for behavioral change. OBJECTIVE To compare the risk of cigarette smoking initiation among waterpipe-only smokers and never smokers in a school-based sample of adolescents from Irbid, Jordan. METHODS A total of 1454 cigarette-naïve participants were drawn from a longitudinal study on smoking behavior conducted in Irbid among 1781 seventh graders who were enrolled at baseline (2008) and completed the study questionnaire on smoking behavior annually until 2011. Grouped time-survival analysis was used to compare the risk of subsequent initiation of cigarette smoking between waterpipe smokers (n = 298) and never smokers (n = 1156) using adjusted hazard ratios (aHRs) and 95% confidence intervals (95%CI). RESULTS Risk of initiation of cigarette smoking among waterpipe smokers was significantly higher than among never smokers after adjusting for potential confounders (aHR 1.67, 95%CI 1.46–1.92). The association between waterpipe and cigarette smoking initiation was dose-dependent. The risk of initiating cigarette smoking increased with increase in the frequency of waterpipe smoking (P for linear trend < 0.001). CONCLUSIONS Waterpipe smoking led to the initiation of cigarette smoking among this cohort of Jordanian adolescents; the effect was dose-dependent. PMID:25860006

    Studies of many years—combining in situ investigation and laboratory analysis—have provided comprehensive information on weathering damage on the rock-cut monuments in the ancient city of Petra in Jordan. These rock-cut monuments represent outstanding world heritage. Many hundred monuments were carved by the Nabataeans from bedrock about 2000 years ago. The awareness of increasing weathering damage on the monuments has resulted in international efforts towards their preservation. The damage diagnosis has addressed the complex mutual relationships between stone types, stone properties, monument exposure regimes, environmental influences, weathering phenomena, development and extent of weathering damage and weathering progression. The rocks were classified lithostratigraphically and petrographically. Results on weathering forms, weathering profiles and weathering products obtained from monument mapping, in situ measurements and laboratory studies revealed a complex diversity of weathering phemomena with respect to type and intensity. Damage categories and damage indices were used to create a reproducible quantitative rating of weathering damage. Detailed results on weathering forms allowed the characterization and quantification of weathering progression including weathering prognoses. Stone properties and states of weathering damage were jointly considered for the rating of the rocks’ susceptibility to weathering. The systematic evaluation of weathering damage and monument exposure regimes can enhance the assessment of weathering factors and processes.

    Understanding changing trends and frequency of extreme rainfall and temperature events is extremely important for optimal planning in many sectors, including agriculture, water resource management, health, and even economics. For people living in the Jordan River region of the Middle East such changes can have immediate devastating impacts as water resources are already scarce and overexploited and summer temperatures in the desert regions can reach 45°C or higher. Understanding shifts in frequency and intensity of extreme events can provide crucial information for planning and adaptation. In this paper we present results from regional climate model simulations with RegCM3 and MM5 centered on the eastern Mediterranean region. Our analysis focuses on changes in extreme temperature and rainfall events. We show that maximum daily summer temperature is expected to increase by between 2.5°C and 3°C, with an increase in warm spell length. Precipitation extremes are expected to increase with longer dry spells, shorter wet spells, and increases in heavy rainfall. Model agreement for the control period 1961-1990 is higher in the southern region than in the north, perhaps because of the complex topography, suggesting that even small differences in spatial scale play an important role. In addition, we notice that the chosen global model plays an important role in determining future temperature trends, while the choice of regional climate model is critical for understanding how precipitation is expected to evolve.

    Recent excavations at Pre-Pottery Neolithic A (PPNA) WF16 in southern Jordan have revealed remarkable evidence of architectural developments in the early Neolithic. This sheds light on both special purpose structures and "domestic" settlement, allowing fresh insights into the development of increasingly sedentary communities and the social systems they supported. The development of sedentary communities is a central part of the Neolithic process in Southwest Asia. Architecture and ideas of homes and households have been important to the debate, although there has also been considerable discussion on the role of communal buildings and the organization of early sedentarizing communities since the discovery of the tower at Jericho. Recently, the focus has been on either northern Levantine PPNA sites, such as Jerf el Ahmar, or the emergence of ritual buildings in the Pre-Pottery Neolithic B of the southern Levant. Much of the debate revolves around a division between what is interpreted as domestic space, contrasted with "special purpose" buildings. Our recent evidence allows a fresh examination of the nature of early Neolithic communities. PMID:21536900

    We study gravitational interaction of Higgs boson through the unique dimension-4 operator ξH{sup †}HR, with H  the Higgs doublet and R  the Ricci scalar curvature. We analyze the effect of this dimensionless nonminimal coupling ξ  on weak gauge boson scattering in both Jordan and Einstein frames. We explicitly establish the longitudinal-Goldstone equivalence theorem with nonzero ξ coupling in both frames, and analyze the unitarity constraints. We study the ξ-induced weak boson scattering cross sections at O(1−30) TeV scales, and propose to probe the Higgs-gravity coupling via weak boson scattering experiments at the LHC (14 TeV) and the next generation pp colliders (50-100 TeV). We further extend our study to Higgs inflation, and quantitatively derive the perturbative unitarity bounds via coupled channel analysis, under large field background at the inflation scale. We analyze the unitarity constraints on the parameter space in both the conventional Higgs inflation and the improved models in light of the recent BICEP2 data.

    A total of 231 different soil Streptomyces isolates were recovered from 16 different locations in North Jordan. They were assessed for their phytotoxic activity on seeds of cucumber (Cucumis sativus L.) and ryegrass (Lolium perenne L.) placed adjacent to a 2 cm wide Streptomyces culture strips grown at 28C degrees for 3 weeks on starch casein nitrate (SCN) agar. Phytotoxicity was ascertained on the basis of suppressed seed germination, discoloration of the root tip, reduced root and the shoot growth and eventual death of the root. Twenty one of the isolates exhibited adverse effect against growth of germinated cucumber seeds, germination and growth of ryegrass seeds. Using filter paper bioassay method, culture filtrate from the SCN broth of the isolate R9; identified as Streptomyces aburaviensis, significantly inhibited seed germination, radicle and shoot growth ofryegrass, reduced radicle and shoot growth of cucumber and suppressed the shoot growth of milk thistle (Silybum marianum L.). Also, culture filtrate from the glucose-peptone-molasses (GPM) broth diluted (1:1) with sterilized distilled water caused complete inhibition of seed germination of redroot pigweed (Amaranthus retroflexus L.). Dichloromethane extracted fraction of S. aburaviensis (strain R9) culture filtrate from GPM broth completely inhibited seed germination of ryegrass when applied at doses of 3 and 5 mg of dry weight, and the seedling growth of cucumber and milk thistle was severely reduced by the same doses.

    Background and Objectives: The global spread of methicillin resistant Staphylococcus aureus (MRSA) constitutes one of the most serious contemporary challenges to the treatment of hospital-acquired infections. We aimed to screen and assess the antibiotic susceptibility pattern of Staphylococcus aureus isolated from clinical specimens in local hospitals of Northern province in Jordan. Materials and Methods: Staphylococcus aureus was isolated and identified using standard methods from various clinical specimens of different infected body sites from 358 patients during the period from January 2008 to November 2012. Results: Our analysis showed that 31.6% of S. aureus infections were MRSA, while 31% were multidrug resistance (MDR) and 42.7% were Oxacillin-resistant (ORSA). Most of these strains were isolated from wound specimens. All isolates were susceptible to vancomycin (100%). They were also susceptible to chloramphenicol, linezolid, nitrofurantoin, rifampicin and teicoplanin (>80%), but showed resistance to erythromycin and penicillin. Conclusion: Vancomycin was the most effective antimicrobial agent against S. aureus. We recommend regular surveillance of hospital associated infections and monitoring antibiotic sensitivity pattern and strict drug policy for antibiotics used within and outside the hospital environments.

  6. Byzantine maritime trade in southern Jordan: The evidence from Port of Aila ('Aqaba).

    NASA Astrophysics Data System (ADS)

    Al-Nasarat, Mohammed

    Eusebius of Caesarea, in (Onomasticon) said that: "Ailath (Aila) is situated at the extremity of Palestine between the southern desert and the Red Sea where cargo was transported by ship from both Egypt and India". There is no doubt that port of Aila- 'Aqaba was important for the sea trade during the Byzantine Period and ancient times. Aila acquired significance in the Byzantine Empire commerce and seafaring according to the information derived from the Byzantine historians, documents and pilgrim's archaeological excavations. This paper focuses on Byzantine Maritime Trade in port of Aila during the period between the fourth and seventh centuries A.D, its importance in the flourishing of trade of southern Jordan, and its relations with other major trade centers such as Gaza, Alexandria and Ethiopia. It appears that port of Aila played a major role in the economy of Byzantine Empire and international trade as attested in the accounts of historians, pilgrims who visited the area during this period, and archaeological excavations which revealed that Aila was at least a transit point and perhaps even a production site for fish sauce or related products in the Byzantine period.

    A regional hydroeconomic model is developed to include demand shifts from nonprice water conservation programs as input parameters and decision variables. Stochastic nonlinear programming then jointly identifies the benefit-maximizing portfolio of conservation and leak reduction programs, infrastructure expansions, and operational allocations under variable water availability. We present a detailed application for 12 governorates in the Hashemite Kingdom of Jordan. It considers targeted installations of water-efficient appliances, leak reduction in the distribution system, surface and groundwater development, seawater desalination, conveyance, and wastewater treatment projects. Results show that (1) water conservation by urban users generates substantial regional benefits and can delay infrastructure expansions; (2) some rationing and conjunctive use operations smooth operations during droughts; (3) a broad mix of source developments, conveyance expansions, and leak reduction programs can forestall the need for desalination; (4) the Disi carrier to Amman should include a large branch to Karak; and (5) increasing conveyance from Ma'an, Irbid, and Mafraq can avert impending crises in the neighboring districts of Tafelah, Ajloun, and Zarqa.

    The purpose of this study is to identify the differences in gender base on numbers, algebra, geometry and mathematics achievement among Jordanian 8th grade school students. The respondent of this study were 337 students from eight public secondary schools in Alkoura district and selected by using stratified random sampling. The study comprised of 179 (53%) males and 158 (47%) females students. The mathematics test comprises of 30 items which has eight items for numbers, 14 items for algebra and eight items for geometry. Finding from independent sample t-test shows that female student score higher than male students in numbers, algebra, mathematics achievement and spatial visualization. There is no significant difference in geometry base for gender. This study also indicates that numbers, algebra and mathematics achievement favorable to female and bias to male students. The main recommendations from this study are for teachers and other educational professionals to focus on the numbers and algebra for male students to improve the learning of mathematics, and feeding program through benefiting from tutorial classes to avoid of weakness in different aspects of mathematics achievement. Gender differences in mathematics in secondary school students in Jordan continue to exist and these differences may influence future educational and occupational pathways.

    A new species of Clariger Jordan & Snyder, 1901 was collected from northern Taiwan. The genus was previously known only from Japanese waters. This discovery is the first formal and southernmost record of these marine gobies from the waters of subtropical Taiwan. The new species, Clariger taiwanensissp. n., is distinguished from its congeners by a unique combination of features: (1) fin rays: dorsal-fin rays III, I/8; anal-fin rays modally I/8; and pectoral-fin rays modally 19 (2+16+1); (2) longitudinal dermal ridge on head with 6 barbels; and (3) specific coloration pattern: head and trunk dark brown with scattered pale spots and blotches; cheek, ventral portion of head sometimes pale with deep brown spots; pectoral-fin base with a dark brown band; and caudal fin mostly dark brown proximally and with alternating and irregular dark brown and pale bands distally. A diagnostic key to all nominal species from Japan and Taiwan is provided. PMID:22711994

    The demographic and economic transition that many developing countries, including Jordan, are undergoing is producing important changes in diet and lifestyle that greatly impact the development of chronic illness. The health behavior of adolescents in developing countries constitutes one of the most serious global challenges we face. The purpose of this study was to explore the wellness appraisal of Jordanian adolescents. It specifically describes the (i) self-care and health history pattern, (ii) to assess physical activity and nutrition appraisal, (iii) quality of life appraisal and (iv) school and outside activities appraisal. A self-administrated questionnaire collected the data from adolescent groups (boys and girls.). A multi-stage stratified random sample was obtained from six public schools by first selecting the educational directorate located in the city of Irbid, which is located in the north of Jordan. A random sub sample of six individual schools was then selected. Individual classes were then selected. A total of 269 boys and 261 girls (12-17-year old) were included in the analysis. The results showed that the students engaged in risky health behaviors which could lead to short- and long-term health problems. The most alarming finding of this study was students' nutritional habits, including less than the daily requirements of fruits, vegetables, milk and meat, while the intake of fast food, soft drinks and sweets were higher than recommended. School-based health promotion and wellness programs should be established in Jordan to influence the health behaviors of adolescents and parents and to avoid further deterioration of their health. Jordanian school curriculum needs to integrate more precise health education programs about diet, exercise, self care and other life style behaviors. More detailed studies are needed with more elaborate instruments about food habits, physical activities and psycho social life. PMID:19304735

  11. Complementary and alternative medicine utilization by a sample of infertile couples in Jordan for infertility treatment: clinics-based survey

    PubMed Central

    2013-01-01

    Background Although there is little information available to quantify the use of complementary and alternative medicine (CAM), growing evidence suggests that CAM prevalence among patients seeking infertility treatment is increasing worldwide. There are many products available on the market and many infertile patients demand information about CAM from their health care providers. This paper investigates the prevalence of CAM use among infertile couples in Jordan. Additionally, trends and factors contributing to CAM use for infertility treatment among these couples have been evaluated. Methods A face-to-face questionnaire inquiring demographic information, use of CAM for medical conditions, in general, and types of CAM used for infertility treatment, in specific, was completed by one thousand twenty one infertile patients attending at two types of facilities; in vitro Fertilization (IVF) centers at both public and private hospitals and infertility private clinics. Both types of facilities were distributed in different areas of Amman, the capital city of Jordan. The study was conducted between May and August 2012. Results Our results show that CAM therapies for infertility treatment were encountered in 44.7% of the study sample. The vast majority of CAM users were females. The most commonly used CAM therapies were herbs and spiritual healing. A clear correlation between the use of CAM for infertility versus the use of CAM for other chronic medical conditions has been found. Conclusions The prevalence of CAM use for infertility treatment in Jordan is relatively high, particularly among young females, well educated and with a low income, in consistence with the studies reported elsewhere. Herbs and spiritual healing are widely used among patients in adjunct to conventional medical interventions. As CAM use is prevalent among patients, there is a clear need for health providers to become more aware of this phenomenon and for further research in this field. PMID:23414246

  12. Provenance of north Gondwana Cambrian-Ordovician sandstone: U-Pb SHRIMP dating of detrital zircons from Israel and Jordan

    A vast sequence of quartz-rich sandstone was deposited over North Africa and Arabia during Early Palaeozoic times, in the aftermath of Neoproterozoic Pan-African orogeny and the amalgamation of Gondwana. This rock sequence forms a relatively thin sheet (1-3 km thick) that was transported over a very gentle slope and deposited over a huge area. The sense of transport indicates unroofing of Gondwana terranes but the exact provenance of the siliciclastic deposit remains unclear. Detrital zircons from Cambrian arkoses that immediately overlie the Neoproterozoic Arabian-Nubian Shield in Israel and Jordan yielded Neoproterozoic U-Pb ages (900-530 Ma), suggesting derivation from a proximal source such as the Arabian-Nubian Shield. A minor fraction of earliest Neoproterozoic and older age zircons was also detected. Upward in the section, the proportion of old zircons increases and reaches a maximum (40%) in the Ordovician strata of Jordan. The major earliest Neoproterozoic and older age groups detected are 0.95-1.1, 1.8-1.9 and 2.65-2.7 Ga, among which the 0.95-1.1 Ga group is ubiquitous and makes up as much as 27% in the Ordovician of Jordan, indicating it is a prominent component of the detrital zircon age spectra of northeast Gondwana. The pattern of zircon ages obtained in the present work reflects progressive blanketing of the northern Arabian-Nubian Shield by Cambrian-Ordovician sediments and an increasing contribution from a more distal source, possibly south of the Arabian-Nubian Shield. The significant changes in the zircon age signal reflect many hundreds of kilometres of southward migration of the provenance. ?? 2006 Cambridge University Press.

    The objective of this work is to assess the potentials and requirements for grey water reuse in Jordan. The results revealed that urban, rural and dormitory grey water production rate and concentration of TS, BOD(5), COD and pathogens varied between 18-66 L cap(-1)d(-1), 848-1,919, 200-1,056, and 560-2,568 mg L(-1) and 6.9E2-2.7E5 CFU mL(-1), respectively. The grey water compromises 64 to 85% of the total water flow in the rural and urban areas. Storing grey water is inevitable to meet reuse requirements in terms of volume and timing. All the studied grey waters need treatment, in terms of solids, BOD(5), COD and pathogens, before storage and reuse. Storage and physical treatment, as a pretreatment step should be avoided, since it produces unstable effluents and non-stabilized sludge. However, extensive biological treatment can combine storage and physical treatments. Furthermore, a batch-fed biological treatment system combining anaerobic and aerobic processes copes with the fluctuations in the hydrographs and pollutographs as well as the present nutrients. The inorganic content of grey water in Jordan is about drinking water quality and does not need treatment. Moreover, the grey water SAR values were 3-7, revealing that the concentrations of monovalent and divalent cations comply with agricultural demand in Jordan. The observed patterns in the hydrographs and pollutographs showed that the hydraulic load could be used for the design of both physical and biological treatment units for dormitories and hotels. For family houses the hydraulic load was identified as the key design parameter for physical treatment units and the organic load is the key design parameter for biological treatment units.

    Lumpy skin disease (LSD) is an emerging disease in the Middle East region and has been recently reported in Jordan. The aim of this study was to investigate the adverse reactions that were reported after vaccine administration. Geographical areas enrolled in the study were free of the disease and away from the outbreak governorate. Sixty-three dairy cattle farms, with a total of 19,539 animals, were included in the study. Of those, 56 farms reported adverse clinical signs after vaccine administration. The duration between vaccine administration and appearance of adverse clinical signs ranged from 1 to 20 days (Mean = 10.3, SD ± 3.9). Clinical signs were similar to those observed with natural cases of lumpy skin disease. These were mainly fever, decreased feed intake, decreased milk production and variable sized cutaneous nodules (a few millimetres to around 2 cm in diameter) that could be seen anywhere on the body (head, neck, trunk, perineum), udder, and/or teats. Nodules were raised and firm initially and then formed dry scabs that could be peeled off the skin. The characteristic deep 'sit fast' appearance was rarely seen and most lesions were superficial. Some cattle had swollen lymph nodes, while a few pregnant animals aborted. The percentage of affected cattle ranged from 0.3 to 25% (Mean = 8, SD ± 5.1). Fever, decreased feed intake, and decreased milk production were seen in 83.9, 85.7, and 94.6% in cattle on the affected farms, respectively. All affected cattle displayed skin nodules over their entire bodies, while 33.9 and 7.1% of the affected farms reported nodular lesions present on the udders and teats, respectively. No mortalities were reported due to vaccine adverse reactions. Duration (course) of clinical signs ranged from 3 to 20 days (Mean = 13.7, SD ± 4.1). Two types of LSD vaccines were used by the farmers in this study. The first one was a sheep pox virus (SPPV) vaccine derived from the RM65 isolate [Jovivac(®) , manufactured by Jordan Bioindustries Centre (JOVAC)] and the other an unlabelled one, which was later identified using PCR as a strain of lumpy skin disease virus (LSDV). Blood and skin samples collected from cattle vaccinated with the LSDV vaccine were positive for LSDV using both general and species-specific PCR primers, whereas those from cattle vaccinated with the Jovivac(®) vaccine were negative. Adverse reactions observed in cattle after administration of the LSDV vaccine were reported to be more severe than those seen after Jovivac(®) vaccine administration and were comparable with clinical signs observed in natural infections.

  15. Teaching Science in Engineering Freshman Class in Private University in Jordan

    A United Nations initiative for the Arab region that established and calculated National Intellectual Capital Index has shown that Jordan is the wealthiest Arab country in its National Human Capital Index (i.e. metrics: literacy rate, number of tertiary schools per capita, percentage of primary teachers with required qualifications, number of tertiary students per capita, cumulative tertiary graduates per capita, percentage of male grade 1 net intake, percentage of female grade 1 net intake) and National Market Capital Index (i.e. metrics: high-technology exports as a percentage of GDP, number of patents granted by USPTO per capita, number of meetings hosted per capita) despite its low ranking when it comes to National Financial Capital (i.e. metric: GDP per capita). The societal fabric in Jordan fully justifies this: the attention paid to education is extreme and sometimes is considered fanatic (e.g. marriage of a lot of couples needs to wait until both graduate from the university). Also, the low financial capital has forced a lot of people to become resourceful in order to provide decent living standard to their beloved ones. This reality is partially manifested in the sharp increase in the number of universities (i.e. 10 public and 20 private ones) relative to a population of around 6.5 million. Once in an engineering freshman classroom, it is totally up to the lecturers teaching science in private Jordanian universities to excel in their performance and find a way to inject the needed scientific concepts into the students' brains. For that, clips from movies that are relevant to the topics and truthful in their scientific essence have been tested (e.g. to explain the pressure on humans due to rapidly increasing "g" force, a clip from the movie "Armageddon" proved very helpful to Physics 101 students, and entertaining at the same time), plastic toys have also been tested to illustrate simple physical concepts to the same students (e.g. a set called The Junior Engineer covers vast concepts relevant to Newton's Laws and Work-Energy Theorem, while originally aimed at 3-year old kids), and YouTube has become so rich in it scientific content that it has not been hard to find any experiment or simulation there so that the students connect the dry blackboard and chalk to real life. As freshmen are still immature and sensing their way through, wondering if they will be able to get the title of Engineer or not, the usage of such familiar mediums and tools such as movies, toys, videos and simulations to illustrate basics to them has proved efficient and is regarded as an ideal ice-breaker towards a challenging journey of engineering classes. As long as the scientific content is not compromised, we believe that more mediums should be tested. This paper will highlight these affairs.

  16. Assessing the potential boron toxicity of soils irrigated with reclaimed water in Jordan

    Carr, Gemma; Nortcliff, Stephen

    2010-05-01

    Boron (B) is a potentially plant toxic ion and is present in domestic treated wastewater (reclaimed water) in Jordan in concentrations of around 1 mg L-1. As reclaimed water is used for irrigation in Jordan the concentration of B gives potential for detrimental effects on crop productivity. Such effects are dependent on the crop type and importantly, the concentration of B in the soil solution and on the readily exchanged component of the soil solid phase. Boron also behaves complexly in soil because it has sorbing tendencies. The sorption of B onto the soil solid phase removes it from solution and effectively reduces its toxicity potential to crops. However, desorption raises its availability in the soil solution and increases the potential for toxicity effects. To investigate B sorption behaviour in Jordanian soils, experimental work was conducted to describe how B sorption and desorption is affected by the concentration of B in the soil solution. Boron isotherms (to show the amount of B sorbed onto the soil surface relative to the amount of B remaining in the soil solution at constant pressure and temperature) were created which showed that the soil had a high affinity to adsorb B and that desorption of B occurs as the concentration of the soil solution is reduced (for example, through the addition of freshwater) to create a new equilibrium between the concentration of B in the soil solution and the amount of B sorbed onto the soil particles. This suggests that freshwater inputs to soil to which B has previously sorbed onto the soil solid phase during irrigation with reclaimed water will lead to the desorption of B, possibly raising the concentration in the soil solution. To test this hypothesis, the B concentration in the soil solution (B in the soil saturation paste extract) of soils irrigated with reclaimed water was determined. This work confirmed that soils to which a greater volume of reclaimed irrigation water had been applied had a higher concentration of B in the soil solution compared to soils to which less water had been applied. The difference was particularly noticeable when the concentration of B was compared to the concentration of non-sorbing chloride in the soil. Boron concentration was also determined by the established method of mannitol calcium chloride abstraction to give both the soluble and specifically and non-specifically sorbed B in the soil. This analysis showed good correlation between the concentration of B in the soil saturation extract and the concentration of B abstracted by mannitol calcium chloride. This correlation effectively describes the proportion of B in the soil which is soluble (determined in the saturation extract) and that which is readily desorbed (the concentration of B abstracted with mannitol calcium chloride minus the concentration in the saturation extract). Further work is needed into this relationship as it could offer a means by which the adsorption capacity of the soil can be rapidly appraised and the leaching requirement (the amount of water needed to desorb and transfer the B through the soil) can be better predicted.

  17. Geochemistry and petrogenesis of the 595 Ma shoshonitic Qunai monzogabbro, Jordan

    The last stage in the formation of the Arabian Nubian Shield in Jordan was dominated by post-orogenic igneous activity of the ˜610-542 Ma Araba Suite, including a monzogabbroic stock intruding the Saramuj Conglomerate, near the southeastern corner of the Dead Sea. The geological setting, petrography, geochemistry and geothermometry of the monzogabbro and other cogenetic varieties are used to shed light on the petrogenesis of this stock and reveal its magma source. The monzogabbro, megaporphyry dikes, and scattered syenite pockets are co-magmatic and alkaline, potassic and shoshonitic in nature. REE and trace elements patterns indicate that these magmas were produced from a mantle that had been modified by subduction-related metasomatism. The parental mafic magma could have been derived by 10% partial melting of LILE-enriched phlogopite-bearing spinel lherzolite, probably lithospheric mantle, in association with post-collisional extension. Fractional crystallization of this parental magma by olivine and pyroxene gave rise to the monzogabbroic magma. The megaporphyry dikes with their giant labradorite plagioclase megacrysts represent feeders of a voluminous volcanic activity that could have lasted for about 105 years. Thermodynamic modeling applying the MELTS software indicates crystallization of this suite in the temperature range of 1184-760 °C at a pressure of 2 kbars, agreeing with olivine-pyroxene, pyroxene, and two-feldspar thermometry. The modeled mineralogy and sequence of crystallization of constituent minerals using MELTS is in remarkable agreement with the observed modal mineralogy of the monzogabbro. Furthermore, a great degree of congruity exists between the modeled and observed chemistry of the major minerals with only minor discrepancies between modeled composition of biotite and olivine.

    Objective Guided by the Attitude-Social influence-self Efficacy (ASE) theory, this study identified predictors of waterpipe (WP) smoking initiation in a WP naïve cohort of Jordanian schoolchildren. Methods A school-based cohort of all 7th grade students (N=1,781) in 19 of 60 schools in Irbid, Jordan, was followed from 2008 to 2011. Generalized linear mixed modeling was used to examine predictors of WP initiation among WP-naïve students (N=1,243). Results During the 3-year study, WP initiation was documented in 39% of boys and 28% of girls. Prior cigarette smoking (boys: Odds Ratio 7.41; 95% Confidence Interval 4.05–12.92 and girls: 8.48; 4.34–16.56) and low WP refusal self-efficacy (boys: 26.67; 13.80–51.53 and girls: 11.49; 6.42–20.55) were strongly predictive of initiating WP. Boys were also more likely to initiate WP smoking if they had siblings (2.30; 1.14- 4.64) or teachers (2.07; 1.12–3.84) who smoked and girls if they had friends (2.96; 1.59–5.54) who smoked. Conclusion There is a sizeable incidence of WP initiation among students of both sexes. These findings will help in designing culturally responsive prevention interventions against WP smoking. Gender-specific factors, refusal skills, and cigarette smoking need to be important components of such initiatives. PMID:25060962

    The Standardized Precipitation-Evaporation Index (SPEI) was applied in order to address the drought conditions under current and future climates in the Jordan River region located in the southeastern Mediterranean area. In the first step, the SPEI was derived from spatially interpolated monthly precipitation and temperature data at multiple timescales: accumulated precipitation and monthly mean temperature were considered over a number of timescales - for example 1, 3, and 6 months. To investigate the performance of the drought index, correlation analyses were conducted with simulated soil moisture and the Normalized Difference Vegetation Index (NDVI) obtained from remote sensing. A comparison with the Standardized Precipitation Index (SPI), i.e., a drought index that does not incorporate temperature, was also conducted. The results show that the 6-month SPEI has the highest correlation with simulated soil moisture and best explains the interannual variation of the monthly NDVI. Hence, a timescale of 6 months is the most appropriate when addressing vegetation growth in the semi-arid region. In the second step, the 6-month SPEI was derived from three climate projections based on the Intergovernmental Panel on Climate Change emission scenario A1B. When comparing the period 2031-2060 with 1961-1990, it is shown that the percentage of time with moderate, severe and extreme drought conditions is projected to increase strongly. To address the impact of drought on the agricultural sector, the irrigation water demand during certain drought years was thereafter simulated with a hydrological model on a spatial resolution of 1 km. A large increase in the demand for irrigation water was simulated, showing that the agricultural sector is expected to become even more vulnerable to drought in the future.

    Introduction To identify sociocultural determinants of self-reported condom use and HIV testing and examine variables related to accessibility, motivation and obstacles among men who have sex with men (MSM) in Jordan. Design Cross-sectional study among MSM who were identified through services of a local non-governmental organization (NGO). Methods Respondents were studied with a semi-structured interview based on the Explanatory Model Interview Catalogue (EMIC) framework. The vignette-based EMIC interview considered locally relevant HIV/AIDS-related knowledge, risk perception and perceived causes, as well as awareness of services and sources of support. Results Of the 97 respondents, 27% reported that they used a condom at last intercourse; 38% had been tested at least once for HIV. Positive determinants of condom use were higher education level, acknowledging MSM as a high-risk group, seeking advice from a medical doctor and the perceived causes “sex with prostitutes” and “sex with animals.” Awareness of available treatment was a positive determinant of HIV testing. Blood transfusion as a perceived cause and asking advice from friends were negative determinants. Conclusions Jordanian MSM seem to be aware of the risk of HIV infection and effective prevention methods, and they are willing to be tested for HIV. Our findings addressed the importance of the sexual meaning of HIV/AIDS on the control of HIV/AIDS among MSM. More effective engagement of NGOs and MSM in the prevention and control of HIV/AIDS is needed, enlisting the support of medical doctors and community health workers. Peer education should be strategically strengthened. Political commitment is needed to mitigate social stigma. PMID:24695243

    The petrographic investigation of a shocked, chalcedony-, quartzine-, and quartz-bearing allochthonous chert nodule (probably Upper Cretaceous) recovered from surficial wadi gravels in the inner parts of the central uplift of the approximately 6 km in diameter Jebel Waqf as Suwwan impact structure, Jordan, reveals new potential shock indicators in microfibrous-spherulitic silica, in addition to well-established shock-metamorphic effects in coarser crystalline quartz. The microcrystalline chert groundmass exhibits a macroscopic dendritic and suborthogonal fracture pattern commonly associated with thin "recrystallization bands" that intersect the pre-existing diagenetic chert fabric. Fibrous aggregates of quartzine spherulites in chalcedony-quartzine-quartz veinlets locally have a shattered appearance and show conspicuous "curved fractures" perpendicular to the quartzine fiber direction (and parallel to [0001]) that commonly trend subparallel to planar fractures (PFs) in neighboring shocked quartz. Quartz exhibits PFs, feather features (FFs), and mainly single sets of planar deformation features (PDFs) parallel to the basal plane (0001) (Brazil twins) and, rarely, additional PDFs parallel to {101¯3}. Shock petrography indicates shock pressures of ≥10 GPa and high shock-induced differential stresses that affected the chert nodule. The internal crosscutting relationships of primary diagenetic and impact-related deformational features together with shockpressure estimates suggest that the curved fractures across quartzine spherulites might represent specific (low- to medium-pressure) shock-metamorphic features, possibly in structural analogy to basal plane PFs in quartz. The dendritic-suborthogonal fractures in the microcrystalline chert groundmass and recrystallization bands are likely related to impact-induced shear deformation and recrystallization, respectively, and cannot be considered as definite shock indicators.

  3. Trend analysis in water quality of Al-Wehda Dam, north of Jordan.

    2014-10-01

    Temporal status and trends in water quality of Al-Wehda Dam, Jordan, from 2006 to 2012 indicate that the dam is subject to a combination of impacts from rainstorm and agricultural runoffs. It also revealed that mineral dissolution, sediment load, rainfall events, evaporation, and water-level fluctuation are the major contributors to variations in water quality. The water chemistry of the impounded Al-Wehda Reservoir showed that Na, Ca, Mg, HCO₃, and Cl are the principal ions, reflecting the dominance of carbonate weathering, with some contribution of silicates. The pH values showed a cyclic pattern with highest values observed in the spring seasons. Total dissolved solids (TDS), Ca, Mg, and HCO₃ are primarily related to leaching and evaporation, with elevated levels that occurred in the rainy winter months. In contrast, seasonal patterns in Na, K, Cl, and NH₄-N contents showed decreased values in winter. Peaks in NO₃-N observed in winter are strongly associated with agricultural runoff. Fluctuations in chlorophyll-a level were coincided with low ratio of total nitrogen (TN) to total phosphorus (TP). Seasonal variations in organic matter content were also apparent, with peaks that generally occurred in spring through early fall corresponding with high algal growth. On an annual basis, the vast majority of water quality data have generally declined, particularly, in 2011. However, it is not clear whether these decreases are related to change in management practices within the Yarmouk basin, or protective measures have been implemented. Comparison of in-lake and post-dam water quality from 2009 to 2011 showed variation in concentrations, where Ca, HCO₃, NO₃-N, Mg, and TDS showed relatively greater post-dam values than in-lake water, whereas pH, Na, Cl, K, COD, BOD₅, and chlorophyll-a were consistently lower in post-dam water. This comparison emphasizes the importance of self-purification capacity of Al-Wehda Dam in reducing some contaminants. PMID:25027776

    The objectives of this study are to report the emergence of lumpy skin disease (LSD) in Jordan and associated clinical signs, complications and preliminary economic losses. In mid-April, 2013, two adult dairy cattle developed clinical signs suggestive of LSD and were confirmed as positive by PCR. The two cases were in Bani Kenanah district, Irbid governorate, on the Jordanian border of Israel and Syria. The disease spread rapidly to all the districts of Irbid governorate. During the month following the emergence of the disease, data were collected related to the epidemiology of the disease and the numbers of affected cattle on the premises. Forty-one dairy cattle holdings were surveyed. The morbidity rate ranged from 3% to 100%, (Mean = 35.1%, SD ±28.5%). The mortality rate ranged from 0% to 20%, (Mean = 1.3%, SD ±4.4%). The case fatality rate ranged from 0% to 100%, (Mean = 6.2%, SD ±22%). The overall morbidity rate was 26%, mortality rate 1.9% and case fatality rate 7.5%. Skin nodules, anorexia, decreased milk production and decreased body weight were common clinical signs, while mastitis and myiasis were seen as complications in a few affected animals. Decreased body weight ranged from 0% to 80%, (Mean = 23.1%, SD ±15.7%). Decreased milk production ranged from 0% to 100%, (Mean = 51.5%, SD ±22.2%). Affected cattle were treated mainly with broad-spectrum antibiotics and anti-inflammatory drugs. The cost of treatment ranged from 0 to 84.3 British Pound/animal, (Mean = 27.9 GBP, SD ±22.5 GBP). LSD continues to spread through the Middle East region and poses a serious threat to the rest of Asia and Europe. International collaboration and communication is warranted to prevent the further spread of the disease to the rest of Asia and Europe. PMID:24148185

  5. Challenges to Stakeholder Participation in Water Reuse for Irrigation in Jordan

    2010-05-01

    Developing new water resources continues to be a challenge in water scarce regions and water reuse offers a sustainable means by which water availability can be maximised. In Jordan, treated domestic wastewater (reclaimed water) already provides a valuable contribution to the annual water budget. This resource is used for irrigation either directly around wastewater treatment plants, or indirectly after reclaimed water released from treatment plants has been transferred though natural waterways and blended with surface runoff. Direct reuse is employed for the irrigation of fodder crops such as barley or alfalfa, while indirect reuse is employed for the irrigation of high-value fruit and vegetable crops grown in the Jordan Valley, a major commercial agricultural area. In order to ensure water reuse is conducted successfully, it is essential that the benefits of reclaimed water (water availability, high nutrient content) are maximised while the potential risks (to human health, soil sustainability and agricultural yields) are minimised. Stakeholder participation in water reuse management decisions could raise the capacity of the water user (such as the farmer) to manage the risks without compromising the benefits of this resource. To investigate the extent to which stakeholders are participating in water reuse management, semi-structured interviews with farmers and institutional representatives were conducted in Jordan. A particular aim of the interviews was to explore the variation in participation between those stakeholders using reclaimed water directly and indirectly. The data collected during 56 interviews with Jordanian farmers showed that the farmers' perception and management of reclaimed water varied considerably between the indirect and direct users. The direct users had a greater level of satisfaction with the water (55 per cent of those asked described the water as "good water") and recognised that they were able to produce larger yields and raise their incomes through this resource. Direct users also felt that communication with the managers of the wastewater treatment plant was more effective and this enabled them to influence the final quality of the water they received (for example, through requesting a reduction in the chlorine concentration in the wastewater effluent due to the negative effect that chlorine has on crop quality). The indirect reuse farmers had a lower level of satisfaction with the reclaimed water (69 per cent of those asked described the water quality as bad). The interviews revealed that few farmers felt included in water resource management decisions and felt unable to discuss water quality concerns with government officials responsible for water distribution. The indirect reuse farmers seemed to be more concerned with water quality management at the individual farm level, through the installation of water filters to reduce the organic load of the water rather than through processes of lobbying or participatory involvement in decision-making to raise the quality of the water through top-down measures such as the enforcement of water quality legislation. The interviews with 29 organisational representatives drew attention to the sensitivity surrounding indirect water reuse which seems to inhibit open discussion of the topic. This is likely to be due to the nature of agriculture at the sites of indirect reuse. Institutional representatives appeared to be concerned with the risk of consumer rejection of produce grown with reclaimed water and the associated negative effects of rejection on agricultural income and employment. A strategy of reduced discussion seemed to be adopted in the attempt to minimise the potential for consumer rejection. The present research proposes that this strategy (adopted with the aim of protecting agriculture) could have the reverse effect though inhibiting the participation of farmers in water reuse planning and management (they are unable to take part in a process in which they are not recognised as being involved). Open discussion of reuse is necessary to accurately identify water quality requirements, drive appropriate legislation and subsequently lead to the enforcement of such legislation. This work shows that a major barrier to participation in water reuse management is the stakeholders' fear that consumer concerns over the use of "waste" resources in food production will reduce marketability. The extent of consumer concerns, in conjunction with stakeholders' perceptions of these concerns, is therefore an important area to be addressed in future research.

    Objectives To investigate if general dental practitioners (GDPs) in private practice in Jordan follow universal guidelines for preparation of anterior teeth for resin bonded all-ceramic crowns (RBCs). Material and Methods A sample (n=100) of laboratory models containing 208 tooth preparations for IPS Empress and In Ceram, featuring work from different GDPs, was obtained from 8 commercial dental laboratories. Aspects of preparations were quantified and compared with accepted criteria defined following a review of the literature and recommendations of the manufactures' guidelines. Results Subgingival margins on the buccal aspect were noticed in 36% of the preparations, 54% demonstrated overpreparation with a tendency to overprepare the teeth on the mesiodistal plane more than buccolingual plane. Twenty percent of samples presented a shoulder finish line while a chamfer margin design was noticed in 39%. Twenty-nine percent and 12% of samples had either a feathered or no clear margin design respectively. Incisal under preparation was observed in 18% of dies of each type. Only 17% of all preparations were found to follow the recommended anatomical labial preparations while 29% of the RBC preparations were found to have the recommended axial convergence angle. In total, 43% of preparations were found to have the recommended depth of the finish line. Conclusions It was found that relevant guidelines for RBC preparations were not being fully adhered to in private practice in Jordan. PMID:21710098

    We investigate the quantum origin of the primordial cosmological gravitational waves in the Brans-Dicke theory in the two conformally related frames, the Jordan-Brans-Dicke frame and the Einstein frame. We calculated the theoretical observable in both frames and we compared both with General Relativity. We compute the number of gravitons Nk produced during inflation and the observables: power spectrum PT, spectral index nT and energy density ?k. The comparison shows that for the case of the particles number Nk the results are the same in both frames and in General Relativity when the Brans-Dicke parameter is much bigger than unity. For the spectral index nT we show that it is possible to get a scale invariant perturbation in the Jordan-Brans-Dicke frame when ??? and in the Einstein frame when ??±?. In both frames, the results found for the power spectrum PT and the energy density ? show that the preferred values of ? are different from that are found in the local tests.

    Prevention is important to reduce the prevalence of preterm births. Although prematurity has been well studied in developed countries, data from developing countries, such as Jordan, are still limited. This retrospective study analysed medical records to determine possible risk factors leading to preterm birth in the Irbid governorate of Jordan. All preterm births during the year 2011 were reviewed. Abstracted data included mother's age and gravidity. Newborn information included gender, birthweight and gestational age at birth. A total of 647 singleton births were included. There were more females than males (54.9% vs. 45.1%), with 75.6% being the second child or more. Half the mothers (50.2%) were 25-35 years of age. Factors associated with preterm birth were male gender (P?=?0.008), maternal age >?35 years (P?=?0.005) and first birth (P?=?0.003). Nurses need to provide support and education to mothers with potential risk about reproductive health and family planning. PMID:25213160

    Water resources in Azraq basin at the northeastern part of Jordan are at critical juncture, due to the continual and excessive abstraction of groundwater accompanied with small amounts of groundwater recharge by precipitation, and high rates of evaporation losses over the entire basin. Groundwater recharge from precipitation over the basin was estimated using soil water balance. It was found that only about 2% to 3 % of annual average rainfall infiltrates ground surface to reach the shallow aquifer. The three dimensional finite difference groundwater flow model MODFLOW (Processing Modflow Pro, version7) was utilized in order to simulate groundwater flow in the basin. Steady state was calibrated using hydraulic conductivity and flows. The calibrated hydraulic conductivity ranged between 0.1 m/day to 7.0 m/day, the system water balance for the steady state showed that spring discharge from the basin was about 15.0 MCM/yr, groundwater recharge by precipitation was about 9.5 MCM/yr, and the trans-boundaries inflow was 5.5 MCM/yr. Transient state was also calibrated using the specific yield ranged between 0.02 to 0.4. Water balance for the year 2002 showed that there are about 40 MCM/yr as water deficit and a maximum drawdown of about 22 m occur in the well field area. Groundwater recharge at five earth dams have been simulated starting from 1995, it was shown that water deficit that occur in 2002 will decreases by about 15 MCM/yr, drawdown has been slightly affected by these recharge dams. This was attributed to the high abstraction rate at the well field area; the second reason is that the locations of these earth dams are far from the well field area. The calibrated model was used to predict the aquifer future subjected to different scenarios, four scenarios were tested to verify the model ability to be a prediction tool. These scenarios showed that continuing with the current abstraction rate which is 57 MCM/yr until year 2025 will lead to an increase of the drawdown of about 14 m. Reducing abstraction rate by 50% of the current rate will reduce the drawdown by about 7 m, where assuming an abstraction rate of 85.5 MCM/yr have produced an increase of drawdown equals to 11 m in the year 2025. Soil Water Atmosphere Plant model (SWAP) was utilized to estimate groundwater recharge from precipitation in the well field area using generated data depending on the soil properties, the results showed that groundwater recharge ranged from 5 % to 8% from the annual average rainfall.

    Broodstock of Verasper moseri (Jordan and Gilbert) aged 3-4 years old were selected, and reinforced cultivation was conducted to promote maturation under controlled water temperature and photoperiod conditions. Fertilized eggs were obtained by artificial fertilization, and the development of embryos, larvae and juveniles was observed continuously. The results showed that the fertilized eggs of V. moseri were spherical, with transparent yolk and homogeneous bioplasm, and had no oil globule inside. The average diameter of the eggs was 1.77±0.02 mm. The eggs of V. moseri were buoyant in water with salinity above 35. The cleavage type was typical discoidal. Young pigment cells appeared when olfactory plates began to form. Hatching occurred at 187 h after fertilization at a water temperature of 8.5°C. The newly hatched larvae, floating on the water surface, were transparent with an average total length of 4.69±0.15 mm. During the cultivation period, when the water temperature was raised from 9 to 14.5°C, 4-day old larvae showed more melanophores on the body surface, making the larvae gray in color. The pectoral fins began to develop, which enabled the larvae to swim horizontally and in a lively manner. On days 7-8, the digestive duct formed. The yolk sac was small and black. The yolk sac was absorbed on day 11. Larvae took food actively, and body length and body height clearly increased. The rudiments of dorsal and anal fin pterygiophores were discernible and caudal fin ray elements formed on day 19. On day 24, the larval notochord flexed upwards, and the rays of unpaired fins began to differentiate. Pigment cells converged on the dorsal and anal fin rays, and the mastoid teeth on the mandible appeared. On day 29, the left eyes of juveniles began to move upwards. Depigmentation began in some juveniles and they became sandy brown in color on day 37. Most juveniles began to settle on the bottom of the tank. The left eyes of juveniles migrated completely to the right side on day 50, when the average body length attained 2.5±0.18 cm, and juveniles accomplished metamorphosis to young. The embryonic and larval characters of several flounder species are compared.

    The study area is located along the Dead Sea Rift, the climate is considered arid in its southern margin near the Dead Sea, which is the lowest water reservoir found on the globe (412 m BSL), to semiarid in its northern part. During the last few decades, the water resources became depleted limiting the natural development of the agricultural settlements, which are the most common type of communities in the region. Previous studies suggested that a large amount of freshwater is lost as the result of salinization processes, which occur when fresh groundwater from the mountain aquifers, flow into the saline clastic Neogene aquifer complex. In order to comprehend this complex system, a detailed outlining of the regional hydrogeological system is essential. Since there are no boreholes, which penetrate the aquiferous rock sequences within the Rift, it was necessary to interpolate a large variety of data from several fields of geosciences. The methods applied included geological mapping, geophysical modeling based on interpretation of seismic profiles and geochemical modeling based on chemical and isotopic analysis of runoff, sediments and groundwater. The combined modeling based on results from the different types of analyses implied to several conclusions relevant to the regional water management policy: (1) groundwater becomes saline as it flows from the margins of the Rift to its center. Therefore, it is recommended to exploit it along the foothills of the rift escarpment. (2) Geophysical modeling indicated that the foothills and the Karstic mountain aquifer extend into the subsurface of the valley and can be farther exploited (up to 15 mm3 per annum) by relatively shallow wells. (3) Several mechanisms of groundwater salinization were deciphered: (a) the dense vertical faulting systems act as potential conduits for saline water, which flow-up from deep-seated sources and penetrate into the fresh aquifers. (b) Fresh groundwater in the clastic aquifer complex is rare, furthermore, two evaporates bodies were encountered (Auja and Zaharat el Qurein), also acting as sources for fresh water salinization. (c) Although the quantity of runoff recharge to the Jordan Valley aquifer complex is negligible, the increase in its salt-content (TDS) turns this negligible freshwater recharge to a significant contributor of salts.

    A comprehensive study on the chemical composition of rainwater was carried out from October 2006 to May 2007 in Ghore El-Safi area western side of Jordan nearby the Dead Sea. Rainwater samples were analyzed for major ions (Ca 2+, Mg 2+, K +, Na +, NH 4+, HCO 3-, Cl -, NO 3- and SO 42-) and trace metals (Fe, Al, Zn, Pb, Cu, and Cd). The highest concentration of elements is observed at the beginning of the rainfall season when large amounts of dust accumulated in the atmosphere scavenged by rain. The majority of rainwater had a neutral or alkaline character as a result of neutralization caused by the alkaline local dusts which contain large amount of CaCO 3. The pH ranged from 4.8 to 8.2 with a mean value of 6.9 ± 0.65 which was in alkaline range considering 5.6 as the neutral pH of cloud water with atmospheric CO 2 equilibrium. In the total 35 rain events, only three events were observed in acidic range (< 5.6) which occurred after continuous rains. The equivalent concentration of components followed the order: Ca 2+ > HCO 3- > Cl - > Mg 2+ > NO 3- > SO 42- > NH 4+ > Na + > K +. Rainwater chemistry was analyzed using Factor Component Analysis to find the possible sources of the measured species. Three components that accounted for 84% of the total variance were extracted sea salts spray (Na+, Cl - and Mg 2+), and soil particles (natural origin), (Mg 2+, Ca 2+ and HCO 3-) and biomass burning (NH 4+). The results obtained in this study are compared with those other studies conducted at different sites in the world. In general, the results of this study suggested that rainwater chemistry is strongly influenced by local anthropogenic sources (potash factory and agricultural activities in Ghore El-Safi area) rather than natural and marine sources. The pollutants in rainwater samples were mainly derived from long distance transport, local industry and traffic sources.

  9. Sources of salinity in ground water from Jericho area, Jordan Valley.

    2001-01-01

    One of the major problems in the lower Jordan Valley is the increasing salinization (i.e., chloride content) of local ground water. The high levels of salinity limit the utilization of ground water for both domestic and agriculture applications. This joint collaborative study evaluates the sources and mechanisms for salinization in the Jericho area. We employ diagnostic geochemical fingerprinting methods to trace the potential sources of the salinity in (1) the deep confined subaquifer system (K2) of Lower Cenomanian age; (2) the upper subaquifer system (K1) of Upper Cenomanian and Turonian ages; and (3) the shallow aquifer system (Q) of Plio-Pleistocene ages. The chemical composition of the saline ground water from the two Cenomanian subaquifers (K1 and K2) point to a single saline source with Na/Cl approximately 0.5 and Br/Cl approximately 7 x 10(-3). This composition is similar to that of thermal hypersaline spring that are found along the western shore of the Dead Sea (e.g., En Gedi thermal spring). We suggest that the increasing salinity in both K1 and K2 subaquifers is derived from mixing with deep-seated brines that flow through the Rift fault system. The salinization rate depends on the discharge volume of the fresh meteoric water in the Cenomanian Aquifer. In contrast, the chemical composition of ground water from the Plio-Pleistocene Aquifer shows a wide range of Cl- (100-2000 mg/L), Na/Cl (0.4-1.0), Br/Cl (2-6 x 10(-3)), and SO4/Cl (0.01-0.4) ratios. These variations, together with the high SO4(2-), K+, and NO3- concentrations, suggest that the salinity in the shallow aquifer is derived from the combination of (1) upconing of deep brines as reflected by low Na/Cl and high Br/Cl ratios; (2) leaching of salts from the Lisan Formation within the Plio-Pleistocene Aquifer, as suggested by the high SO4(2-) concentrations; and (3) anthropogenic contamination of agriculture return flow and sewage effluents with distinctive high K+ (80 mg/L) and NO3- (80 mg/l) contents and low Br/Cl ratios (2 x 10(-3)). Our data demonstrates that the chemical composition of salinized ground water can be used to delineate the sources of salinity and hence to establish the conceptual model for explaining salinization processes.

  10. Upper Cretaceous (Campanian) phosphorites in Jordan: implications for the formation of a south Tethyan phosphorite giant

    A record of sedimentary, authigenic, and biological processes are preserved within the Upper Cretaceous (Campanian) Alhisa Phosphorite Formation (AP) in central and northern Jordan. The AP formed near the eastern extremity of the south Tethyan Phosphorite Province (STPP), a carbonate-dominated Upper Cretaceous to Eocene "phosphorite giant" that extends from Colombia, North Africa to the Middle East. Multidisciplinary research of the AP and associated cherts, chalks, and oyster buildups indicate that phosphatic strata formed on a highly productive, storm-dominated, east-west trending epeiric platform along the south Tethyan margin. The onset of phosphogenesis and the accumulation of economic phosphorite coincided with a rise in relative sea level that onlapped peritidal carbonates of the Ajlun Group. Pristine phosphates are associated with well-developed micrite concretionary horizons and contain abundant non-keeled spiral planktic foraminifera and a low diversity benthic assemblage of Buliminacean foraminifera, suggesting that pristine phosphates are a condensed facies and phosphogenesis was stimulated by the effects of a highly productive surface ocean and the suboxic diagenesis of sedimentary organic matter. The bulk sediment composition and absence of Fe-bearing authigenic phases such as glauconite, pyrite (including pyrite molds), siderite, and goethite within pristine phosphates suggests that deposition and authigenesis occurred under conditions of detrital starvation and that "iron-pumping" played a minimal role in phosphogenesis. Authigenic precipitation of phosphate occurred in a broad array of sedimentary environments—herein termed a "phosphorite nursery"—that spanned the entire platform. This is a non-uniformitarian phenomenon reflecting precipitation of sedimentary apatite across a wide depositional spectrum in a variety of depositional settings, wherever the conditions were suitable for phosphogenesis. Sedimentologic data indicate that pristine phosphates were concentrated into phosphatic grainstones through storm wave winnowing, and storm-generated, shelf-parallel geostrophic currents. Economic phosphorites formed through the amalgamation of storm-induced event beds. Stratigraphic packaging of phosphatic strata indicates that temporal variations in storm frequency were a prerequisite for the formation of economic phosphorite. Syndepositional phosphogenesis, reworking, and amalgamation to form phosphorites contrasts sharply with the principles of "Baturin Cycling". A transgressive systems tract coupled with high surface productivity created detritally starved settings favourable for phosphogenesis; storm reworking of pristine phosphate facies produced granular phosphorite; and amalgamation of storm-generated granular event beds formed economic phosphorite in a single systems tract.

  11. Continuity and change in ceramic manufacture: Archaeometric study of Late Byzantine-Early Islamic transition in Jordan

    Alawneh, Firas Mohamad

    This thesis investigates continuity and change of ceramics from Late Byzantine-Early Islamic transition period Jordan. The transition period has been characterized largely by an overlap of two ceramic traditions. The material culture of this period has been primarily viewed through formal and stylistic changes. However, ceramic technology and distribution have never been subjected to rigorous analytical study. In order to explain continuity and change in ceramic tradition the undertaken study has focused on the provenance and technology, using multifaceted analytical approach. This study of the transition period pottery has focused on the classification and technological features of potsherds from selected sites in Jordan (Amman, Aqaba, Beit Ras, Khirbet el-Nawafleh, Jarash, Jericho, Pella, Madaba, Gharndal, Humaimah, Um er-Rassas and Um el-Waleed). Samples were studied by particle-induced X-ray emission spectroscopy, X-ray powder diffraction, and optical microscopy to analyze their chemical, mineralogical and textural features in the aim of determining their possible provenance and production technology. Compositional data were statistically processed with multivariate analysis using SYSTAT II software 2006. To obtain further information about possible source areas of raw materials used in ceramic production, clays were also sampled in the studied areas. Firing experiments were conducted for clays with compositions comparable with those of ceramic sherds, to better understand the firing technology of the pottery. The multifaceted analytical approach has revealed important information on ceramic production in Transjordan. Khirbet el-Nawafleh and Aqaba in the south, Jarash and Pella in the north, Amman and Madaba in the middle are possibly just a few important production centers during this period. The study shows a multidirectional socio-cultural exchange and economic trade patterns within each region and between adjacent regions, as well. Also, importation from adjacent provinces cannot be excluded for certain samples. Despite the different archaeological levels to which these samples belong to, this study illustrates some similarity in technological features and chemical composition. This in turn suggests that continuity is rather the trend in ceramic tradition of the society during the transition period. However, further work on clays, kilns, and pottery from other sites discovered in Jordan is necessary to confirm this conclusion.

    The Mediterranean summer sea breeze front (SBF) climatic features of penetration into the complex topography of the Jordan Rift Valley (JRV) were investigated. It was shown that the SBF penetration into the JRV occurs in a well-defined chronological order from north to south. One exception to this general rule is the breeze penetration of Sdom, which occurs after it has penetrated the Arava which is located further south, probably due to the micro-climatic effect of the Dead Sea. It was also noted that the breeze increases the local specific humidity as it reaches the JRV in spite of significant temperature increases. The temperature reaches its daily peak 2 to 3 h later in the southern valley compared to the northern valley and is suggested to be due to the later SBF penetration and the valley structure. The pre-SBF line features in the JRV are described.

    This study was conducted to determine the prevalence and the local antibiogram of multidrug-resistant Acinetobacter baumannii isolates in Al-Hussein Hospital at King Hussein Medical Centre in Amman, Jordan. In a retrospective study from January to December 2013, data on 116 non-repetitive positive clinical samples were retrieved from patients' laboratory records. The resistance rates of A. baumannii isolates were high for ceftriaxone, cefotaxime and ticarcillin (100%), ceftazidime, cefepime and piperacillin (98.3%), imipenem (97.4%), piperacillin/tazobactam (96.6%), quinolones (94.8%), ampicillin/sulbactam (89.7%), gentamicin, (87.9%), tobramycin and tetracycline (76.7%) and trimethoprim/sulfamethoxazole (75.9%), but lower for minocycline (26.7%) and colistin (1.7%). A. baumannii in our hospital were highly resistant to all antibiotics, including tigecycline, except for minocycline and colistin which are considered the last resort treatment for multidrug-resistant A. baumannii.

    The inverse scattering method of Belinsky and Zakharov is used to investigate axially symmetric stationary vacuum soliton solutions in the five-dimensional representation of the Brans-Dicke-Jordan theory of gravitation, where the scalar field of the theory is an element of a five-dimensional metric. The resulting equations for the spacetime metric are similar to those of solitons in general relativity, while the scalar field generated is the product of a simple function of the coordinates and an already known scalar field solution. A family of solutions is considered that reduce, in the absence of rotation, to the five-dimensional form of a well-known Weyl-Levi Civita axially symmetric static vacuum solution. With a suitable choice of parameters, this static limit becomes equivalent to the spherically symmetric solution of the Brans-Dicke theory. An exact metric, in which the Kerr-scalar McIntosh solution is a special case, is given explicitly.

    Brucellosis is considered endemic in many Middle Eastern countries including Jordan. To determine the frequency, risk factors and spatial distribution of ruminant brucellosis in Jordan, a nationwide cross-sectional study was conducted. Small ruminant flocks (n=333) and cattle herds (n=204) were randomly selected, and their disease status was ascertained by testing individual serum samples using the Rose Bengal Test and a competitive ELISA (sheep and goats) and milk samples using an indirect ELISA (cattle). Information on putative risk factors was collected using standardized questionnaires. A logistic model with a binomial outcome was built to identify risk factors for being seropositive. The estimated true seroprevalence values were 18.1% (95% CI: 11-25.3) (cattle-only herds), 22.2% (95% CI: 16.5-28.8) (sheep flocks), 45.4% (95% CI: 30.3-61.6) (goat herds), 70.4% (95% CI: 55.5-84.9) (mixed sheep-goat flocks), 34.3% (95% CI: 28.4, 40.4) (all small ruminant flocks) and 38.5% (95% CI: 24.3-51.8) (mixed herds of cattle and small ruminants). Only 1.5% of small ruminant flocks were vaccinated. The seroprevalence was higher in northern areas, where livestock density is also higher. The logistic model fitted the data well and had a very high predictive ability. In the small ruminant model, five variables were significantly associated with a higher odds of seropositivity: lending/borrowing rams (OR=8.9, 95% CI: 3.0-26.1), feeding aborted material to dogs (OR=8.0, 95% CI: 3.5-18.1) the presence of goats (OR=6.9, 95% CI: 3.1-15.4), introducing new animals to the flock (OR=5.8, 95% CI: 2.5-13.6), and a large flock size (OR=2.2, 95% CI: 1.0-4.6). Conversely, separating newly introduced animals (OR=0.16, 95% CI: 0.05-0.47), separating animals that had aborted (OR=0.19, 95% CI: 0.08-0.46) and using disinfectants to clean pens (OR=0.37, 95% CI: 0.16-0.83) were significantly associated with a lower odds of being seropositive. The main risk factor for cattle herds being seropositive was the introduction of new animals (OR=11.7, 95% CI: 2.8-49.4); while separation of newly introduced animals (OR=0.09, 95% CI: 0.03-0.29), herd disinfection (OR=0.04, 95% CI: 0.01-0.15) and having calving pens (OR=0.14, 95% CI: 0.05-0.43) significantly reduced the odds of infection. Brucellosis is endemic at high levels across Jordan, and the current vaccination programme, which is limited to small ruminants, has very low coverage. A revised brucellosis control programme is required in Jordan. Given the high baseline prevalence, it should be based on vaccination accompanied by measures to promote hygiene and husbandry practices that minimize the risk of introduction and maintenance of Brucella spp., and thereby the risk of human infection.

The new species most closely resembles Philometra gymnosardae and Philometra ophisterni; however, P. poblana can be easily differentiated from the other species by the length of gravid females (7.10-10.43 vs. 14.8-27.0 and 28.67-39.30 mm, respectively), length of caudal projections (0.015-0.023 vs. 0.047 and 0.006-0.009 mm high, respectively), site of infection (skin at base of pectoral fins vs. abdominal cavity, both species), and the host species (Cichlidae vs. Synbranchidae and Scombridae).

    The Nonsymmetric Kaluza-Klein (Jordan-Thiry) Theory leads to a model of a modified acceleration that can fit an anomalous acceleration experienced by the Pioneer 10 and 11 spacecraft. The future positions of those spacecrafts are predicted using distorted hyperbolic orbit. A connection between an anomalous acceleration and a Hubble constant is solved in the theory together with a relation to a cosmological constant in CDM? model. In the paper we consider an exact solution of a point mass motion in the Solar System under an influence of an anomalous acceleration. We find two types of orbits: periodic and chaotic. Both orbits are bounded. This means there is no possibility to escape from the Solar System. Some possibilities to avoid this conclusion are considered. We resolve also a coincidence between an anomalous acceleration and the cosmological constant using a paradigm of modern cosmology. Relativistic effects and a cosmological drifting of a gravitational constant are considered. The model of an anomalous acceleration does not cause any contradiction with Solar System observations. We give a full statistical analysis of the model. We consider also a full formalism of the Nonsymmetric Jordan-Thiry Theory for the problem and present a relativistic model of an anomalous acceleration. We consider the model for General Relativity approximation, i.e. inline image (inline image). In this model there are no contradictions with General Relativity tests in the Solar System. Pioneer 10/11 spacecrafts will come back in 106 years (a time scale of our periodic solutions is 106 years). Moreover, almost relativistic or relativistic spacecrafts can escape from the Solar System. We consider also a model of a relativistic acceleration which is more complicated, with inline image taken into account.

    Optimization of drug therapy and preventing drug-related problems (DRPs) are major factors to improve health care, reduce expenditure, and potentially save lives. This study aimed at describing the types, numbers, and frequencies of DRPs in the outpatient settings of a group of hospitals in Jordan. The study was set in the cardiology, endocrine, and respiratory outpatient clinics of five major hospitals in Jordan. Patients who visited the above clinics during the period from September 2012 to December 2013, were candidates for this study. Each included subject was fully assessed for DRPs by clinical pharmacists according to a specially designed and validated pharmaceutical care manual. The main outcome measures were the number and types of DRPs. Data were collected from 2,898 patients (mean age ± standard deviation: 56.59±13.5 years). The total number of identified DRPs was 32,348, with an average of 11.2 DRPs per patient. The most common DRPs were a need for additional or more frequent monitoring, a problem in patients' adherence to self-care activities or nonpharmacological therapy, and that the patient was not given instruction in or did not understand nonpharmacological therapy or self-care advice. The numbers of DRPs per patient in our sample were associated with older age (>57 years), being unmarried, having an education level of high school or less, not having health insurance, and the presence of certain clinical conditions, including hypertension, diabetes mellitus, dyslipidemia, ischemic heart disease, cardiac catheterization, heart failure, and gout. In conclusion, implementation of clinical pharmacy services is a strategy to limit DRPs. Certain patient populations are more vulnerable to DRPs. PMID:26937195

    The fortification of wheat flour with micronutrients is a common strategy to increase vitamin and mineral intake. While wheat flour mills are often inspected by agencies affiliated with national ministries to ensure compliance with national fortification standards, few countries use data derived from these inspections to construct an external monitoring system for use in program management and evaluation. The primary objective of this paper is to assess the performance of the external monitoring system utilized in Jordan according to the US Centers for Disease Control and Prevention's Updated Guidelines for Evaluating Public Health Surveillance Systems. A secondary objective is to present mill monitoring results from 2009 to 2010 in order to demonstrate the data generated by the system. The review concludes that the data required for the system is representative, simple to collect, and can be collected in a flexible manner. The external monitoring system is acceptable to participating agencies and millers and is stable due to mandatory fortification legislation which provides the legal framework for external monitoring. Data on production of fortified flour and utilization of premix can be provided in a timely manner, but on-site mill monitoring and flour sample collection are more challenging due to resource constraints. The frequent collection of a small number of indicators can provide fortification program managers with timely information with which to base decisions. Jordan's external monitoring system successfully documented the performance of each mill and the entire flour fortification program, and can serve as a model for other national fortification programs considering external monitoring approaches.

    Optimization of drug therapy and preventing drug-related problems (DRPs) are major factors to improve health care, reduce expenditure, and potentially save lives. This study aimed at describing the types, numbers, and frequencies of DRPs in the outpatient settings of a group of hospitals in Jordan. The study was set in the cardiology, endocrine, and respiratory outpatient clinics of five major hospitals in Jordan. Patients who visited the above clinics during the period from September 2012 to December 2013, were candidates for this study. Each included subject was fully assessed for DRPs by clinical pharmacists according to a specially designed and validated pharmaceutical care manual. The main outcome measures were the number and types of DRPs. Data were collected from 2,898 patients (mean age ± standard deviation: 56.59±13.5 years). The total number of identified DRPs was 32,348, with an average of 11.2 DRPs per patient. The most common DRPs were a need for additional or more frequent monitoring, a problem in patients’ adherence to self-care activities or nonpharmacological therapy, and that the patient was not given instruction in or did not understand nonpharmacological therapy or self-care advice. The numbers of DRPs per patient in our sample were associated with older age (>57 years), being unmarried, having an education level of high school or less, not having health insurance, and the presence of certain clinical conditions, including hypertension, diabetes mellitus, dyslipidemia, ischemic heart disease, cardiac catheterization, heart failure, and gout. In conclusion, implementation of clinical pharmacy services is a strategy to limit DRPs. Certain patient populations are more vulnerable to DRPs. PMID:26937195

    Chronic obstructive pulmonary disease (COPD) is a leading cause of morbidity and mortality worldwide. The prevalence of COPD among cigarette smokers in the Middle East is not well studied. A prospective descriptive study was performed in the north of Jordan. Male cigarette smokers (≥10 pack-year) aged 35 years and older were recruited from the community. They completed a questionnaire and a postbronchodilator spirometry. Global Initiative for Chronic Obstructive Lung Disease (GOLD) criteria (postbronchodilator forced expiratory volume in 1 second <70%) was used to define COPD. A total of 512 subjects completed the study protocol. According to the GOLD criteria, 42 subjects (8.2%) had COPD. Of those, 27 subjects (64.3%) had symptomatic COPD. Using the GOLD criteria, eight subjects (19%) with COPD had mild disease, 24 (57.1%) had moderate disease, eight (19%) had severe disease, and two (4.8%) had very severe disease. Only 10.6% were aware of COPD as a smoking-related respiratory illness, and 6.4% had received counseling about risk for COPD by a physician. Chronic bronchitis (cough for 3 months in 2 consecutive years) was reported by 15% of the subjects, wheezes by 44.1%, and dyspnea by 65.2%. Subjects with COPD reported having more chronic bronchitis 18/42 (42.9%) and wheezing 28/42 (66.7%) than subjects without COPD. The prevalence of COPD increased with increased number of pack-years smoked. In conclusion, COPD prevalence among cigarette-smoking men in Jordan is lower than in the developed world. COPD was largely underdiagnosed, despite the majority of participants being symptomatic and having moderate to severe disease. PMID:25092972

    A total of 29 brain tissue samples (BTS) were examined for rabies infection by different diagnostic techniques. None of the examined brain tissues were presented as a whole intact brain. Twenty-seven brain tissue samples from various animal species - dog (13 cases), cat (one case), fox (one case), pig (one case), cow (three cases), sheep (two cases), goat (one case), camel (one case), horse (one case) and donkey (three cases) - were provided by the Vaccine and Sera Department/Al-Bashir Central Hospital in Amman/Jordan from July 2009 up to May 2010. All these samples were frozen at -20°C, for a period of time and then fixed in 10% formalin after being tested for rabies virus by fluorescence antibody test (FAT). The results showed that 21 (77.77%) of 27 BTS were positive for rabies by FAT. Seventeen samples (58.62%) of 29 were positive by histopathology, 2 (6.90%) were positive by histopathology, immunohistochemistry (IHC) and of those which were fixed for 24h only, and 21 (72.42%) were positive using RT-PCR assay. Five of 29 BTS had no pathological lesions, 17 had Negri bodies and the remaining had non-suppurative encephalitis and necrosis. Thirteen BTS that were diagnosed positive by FAT were also positive by RT-PCR and histopathology, but negative by IHC. Four BTS that were positive by FAT were negative by histopathology, IHC and RT-PCR. Also, 3 BTS (cases 19, 22, and 25) that were negative by FAT were positive by RT-PCR and negative by IHC. One of these was negative, while two were positive by histopathology. Therefore, definitive diagnosis of rabies under these conditions in Jordan needs one or more other diagnostic tests in addition to FAT. Also, freezing and prolonged formalin fixation of BTS is not suitable for the detection of rabies virus antigen using IHC. PMID:22390575

  4. Geomorphology of Lake Lisan terraces along the eastern coast of the Dead Sea, Jordan

    Lake Lisan, the lake that filled the Jordan graben during the Last Glacial, left behind a well developed sequence of erosional and depositional shore terraces in the south east of the current Dead Sea. These terraces record a series of stillstands that were caused by small transgressions within an overall trend of falling lake levels. The terraces were observed in places where they had not been identified previously. The morphology of the terraces was investigated in six cross-sections using differential GPS altimetry. The levels of the terraces range between - 370 and - 148 m a.s.l. The high stand of Lake Lisan at - 148 m correlates well with the high level of - 150 m reported by Bowman and Gross [Bowman, D., Gross, T., 1992. The highest stand of Lake Lisan: ~ 150 meters below MSL. Israel Journal of Earth-Science 41, 233-237.] along the western coast of Lake Lisan. The lake terraces are horizontal, elongated and tectonically undisturbed, and have a sub-horizontal foreshore (tread) with an average slope of 8.2° and steep backshore cliff (riser) with an average slope of 17.7°. The six cross-sections show a good altitudinal correlation between their terraces. Moreover, the terraces appear in undisturbed continuity on the aerial photos. These morphological characteristics demonstrate that the retreat of the lake was a result of substantial climatic changes, not of tectonic subsidence. In-situ stromatolites were found on most of the terraces, reflecting a shallow water environment and emphasizing that these terraces are recessional. Well-developed desert varnish and Tafoni observed on blocks sitting on the terrace surfaces imply a long period of exposure and a low rate of post lacustrine erosion. The formation of Lisan terraces is constrained mainly by coastal slope, water depth and underlying lithology. The morphological analysis of these terraces allows identification of two kinds of pseudo-terraces, which were formed as a result of tread or riser destruction. U/Th and OSL dating allowed the dating of three events within the lake level curve more precisely. The high level of - 148 m occurred at 30.5 ± 0.22 ka BP, consistent with the Heinrich Event 3 and Dansgaard-Oeschger stadial 5, the coldest period in the NGRIP Greenland Ice Core record. The next lower terrace at - 154 m was formed at 22.9 ka BP ± 0.29 and corresponds to the stadial 2C, the final phase of the Last High Glacial. The correlation between the Lisan high stands and climatic stadials suggests that Northern-Hemispheric cold periods led to periods with a more positive water balance in the Near East. At ~ 10 ± 0.8 ka BP Lake Lisan experienced a sharp drop to - 200 m followed by a transgression between 9.5 to 7 ka BP.

  5. Using environmental isotopes in the study of the recharge-discharge mechanisms of the Yarmouk catchment area in Jordan

    Salameh, Elias

    The recharge sources, the flow mechanisms and discharge areas of the different groundwater bodies underlying the Yarmouk River catchment area in Jordan, have, until now, not been adequately explained, although a wide range of hydrological, hydrogeological, and hydrochemical studies have been done. Along the Jordanian part of the catchment area of the Yarmouk River, groundwater issues from different aquifers with a variety of chemistries and types within the same aquifer and in between the different aquifers. Conventional recharge/discharge mechanisms, water balances and chemical analyses did not adequately explain the chemical variations and the different water types found in the area. Applying environmental isotopic tools combined with their altitude effects due to topographic variations (250-1,300 m a.s.l. within a distance of 20 km), and taking into consideration re-evaporation effects on the isotopic depletion and enrichment of rainwater, has greatly helped in understanding the recharge discharge mechanisms of the different aquifers. Precipitation along the highlands of an average of 600 mm/year is found to be depleted in its isotopic content of ?O18 = -7.0 to -7.26 and ?D = -32.2 to -33.28, whereas that of the Jordan Valley of 350 mm/year is highly enriched in isotopes with ?O18 = -4.06 and ?D = -14.5. The groundwater recharged along the highlands is depleted in isotopes (?O18 = -6, ?D = -30), groundwater at the intermediate elevations is enriched (?O18 = -5, ?D = -23) and that of the Jordan Valley aquifers containing meteoric water is highly enriched (?O18 -3.8, ?D = -18). The deep aquifers in the Jordan Valley foothills are depleted in isotopes (?O18 -18 = -6, ?D = -30) and resemble those of the highland aquifers. Only through using isotopes as a tool, were the sources of the different groundwater bodies and recharge and discharge mechanisms unambiguously explained. It was found that recharge takes place all over the study area and produces groundwater, which, from the highlands towards the Jordan Valley, shows increasing enrichment in isotopes. The highlands aquifer, with its groundwater depleted in isotopes, becomes confined towards the Jordan Valley; and, due to its confining pressure, leaks water upwards into the overlying aquifers causing their water to become less enriched in isotopes. Water depleted in its isotopic composition also seeps upward to the ground surface at the mountain foothills through faults and fissures. Les zones de recharge, les mécanismes d'écoulement et les zones de décharges des différentes masses d'eau souterraine sous le bassin versant de la rivière Yarmouk en Jordanie, étaient expliquées de manière ambiguë par les seuls outils isotopiques. Le long de la parti Jordanienne du bassin versant de la rivière Yarmouk l'eau souterraine provient de différents aquifères et se distinguent par leur type et leur composition chimique, selon que l'eau provient du même ou des différents aquifères. Les mécanismes conventionnels de recharge et de décharge, bilan hydrologique ne donnaient pas d'explications satisfaisantes concernant les variations chimiques et les différents types d'eau. En appliquant les isotopes environnementaux combinés aux effets de l'altitude sur les variations des teneurs isotopiques (l'altitude varie de 250 à 1,300 m sur une distance de 20 km.) et en prenant en considération les effets de ré-évaporation sur l'appauvrissement et l'enrichissement isotopique des eaux pluviales ont fortement contribués à une meilleure compréhension des mécanismes de recharge des différents aquifères. Les précipitations annuelles sont comprises entre 600 mm dans les zones en altitude et 350 mm dans la vallée de la Jordanie. Les écoulements de l'eau souterraine sont dirigés des zones en altitude vers la vallée de la Jordanie. Les eaux souterraines des zones en altitude sont isotopiquement appauvries (?O18 = -6, ?D = -30), les eaux souterraines des zones de moyenne altitude sont enrichies (?O18 = -5, ?D = -23) et les eaux de la vallée très enrichies (?O18 -3.8, ?D = -18). Les aquifers profonds dans la vallée de la Jordanie sont appauvris (?O18 -18 = -6, ?D = -30) et se confondent avec les eaux des zones situées en altitude. En appliquant uniquement les isotopes environnementaux comme des outils de compréhension des phénomènes hydrogéologiques, la source des différentes masses d'eau souterraines, les mécanismes de la recharge et de la décharge pourraient être expliqués de manière ambiguë. Las fuentes de recarga, los mecanismos de flujo y las áreas de descarga de los diferentes cuerpos de agua subterránea que subyacen el área de la cuenca del Río Yarmouk en Jordania, se han explicado de manera no ambigua únicamente mediante la aplicación de los isótopos como herramienta. A lo largo de la parte Jordana del área de la cuenca del Río Yarmouk el agua subterránea emerge de diferentes acuíferos con una variedad de tipos y composiciones, ya sea que provengan del mismo acuífero o de diferentes acuíferos. Los mecanismos convencionales de recarga/descarga, balances hídricos y variaciones químicas no han podido explicar las variaciones químicas y los diferentes tipos de aguas. La aplicación de herramientas de isótopos ambientales combinadas con los efectos de altitud derivados de variaciones topográficas (250 hasta 1,300 m s.n.m. en una distancia de 20 km) y tomando en consideración los efectos de re-evaporación en el empobrecimiento de isótopos y enriquecimiento del agua de lluvia han ayudado fuertemente en el entendimiento de los mecanismos de recarga/descarga de los diferentes acuíferos. La precipitación en el área varía de 600 mm/año, a lo largo de las tierras altas, a 350 mm/año en el área del Valle Jordán. El flujo de agua subterránea ocurre de las tierras altas hacia el Valle Jordán. El agua subterránea de las tierras altas está empobrecida en isótopos (?O18 = -6, ?D = -30), el agua subterránea de elevaciones intermedias está enriquecida (?O18 = -5, ?D = -23), y el agua de los acuíferos del Valle Jordan contiene agua meteórica que se encuentra altamente enriquecida (?O18 = -3.8, ?D = -18). Los acuíferos profundos que se localizan al pie de las tierras altas del Valle Jordán están empobrecidos en isótopos (?O18 = -6, ?D = -30) y son similares a los acuíferos de las tierras altas. Solo al aplicar los isótopos ambientales como herramienta pudo explicarse de manera inequívoca las fuentes de los diferentes cuerpos de agua subterránea y los mecanismos de recarga y descarga.

    This survey in primary health-care centres in north Jordan aimed to assess health-care providers' perceptions of their knowledge, skills and preparedness for disaster management. A multistage random sample was used to recruit nurses and physicians from 57 health centres. A total of 207 participants completed the Arabic version of the Disaster Preparedness Evaluation Tool. Participants perceived themselves as having moderate preparation for disaster management [mean score 74.9 (SD 21.6)], moderate knowledge [mean 49.9 (SD 12.3)] and moderate to weak skills in disaster management [mean 35.3 (SD 12.7)]. Significant differences were revealed in participants' perceptions of their disaster preparedness, knowledge and skills according to their sex, specialty and exposure to a real disaster situation. Further education and training courses are needed to enhance providers' preparedness for disaster management in Jordan. PMID:26750161

    Anecdotes, both historical and recent, recount the curing of skin infections, including diaper rash, by using red soils from the Hashemite Kingdom of Jordan. Following inoculation of red soils isolated from geographically separate areas of Jordan, Micrococcus luteus and Staphylococcus aureus were rapidly killed. Over the 3-week incubation period, the number of specific types of antibiotic-producing bacteria increased, and high antimicrobial activity (MIC, approximately 10 microg/ml) was observed in methanol extracts of the inoculated red soils. Antibiotic-producing microorganisms whose numbers increased during incubation included actinomycetes, Lysobacter spp., and Bacillus spp. The actinomycetes produced actinomycin C(2) and actinomycin C(3). No myxobacteria or lytic bacteriophages with activity against either M. luteus or S. aureus were detected in either soil before or after inoculation and incubation. Although protozoa and amoebae were detected in the soils, the numbers were low and did not increase over the incubation period. These results suggest that the antibiotic activity of Jordan's red soils is due to the proliferation of antibiotic-producing bacteria. PMID:19286796

    Groundwater flow in the Northwestern highlands of Jordan is controlled y the Ajlun Heights were groundwater flows towards north and west along the Yarmouk river and the Jordan Valley. Due to water rock interactions, groundwater that discharges in the Jordan Valley and along the Yarmuk River is thermal, radioactive and mineralized. Its total dissolved solids especially in the confined parts of the aquifer. Electrical conductivity of groundwater in the unconfined aquifer of B2A7 ranges between 500 to 700 µs/cm and increases up to 1600 µs/cm towards the confined part of the aquifer with a notable increase in Na and Cl towards the discharge areas. According to the chloride content in the groundwater the evaporation in the recharge areas is considered to be high representing 82% of the total rainfall. Groundwaters are classified as calcium bicarbonate types with Mg/Ca ratios varying from 0.11 to1.21 and Na/Cl ratio in the range of 0.49 to 1.85. The chemical evolution of groundwater from Ajlun Heights toward Jordan Valley and Yarmouk River is marked by a progressive decrease in calcium and bicarbonate with increase of sodium, and chloride due to halite dissolution and upward percolation of deep saline groundwater. The 3D modeling for the aquifer system indicated the rule of geologic structure in the groundwater digenesis through upward and downward leakage enhanced along high permeability lineaments. According to the modeled water budget, the inflow to the upper B2A7 Aquifer 54 *106 m3/yr replenishing the B2A7 system as underground flow in the karstic limestone of the vadose zone. The underground discharge to the Yarmouk River and Jordan valley modeled to be 23.2 *106 m3/yr as underflow to the springs. The leakage from B2A7 aquifer into the lower aquifer is about 9.7 *106 m3/yr. Within the north western lowered elevations the hydraulic different between upper and deep aquifers is at minimum an upward leakage and seems to take place through the main faults trending EW which was estimated to be 19 *106 m3/yr reflected by the groundwater elevated temperature and anomalies in the analyzed trace element such as Sr. Key words: Yarmouk river, B2A7 Aquifer, groundwater interaction, leakage

    An immature (Ro=0.39%), S-rich (S(org)/C = 0.07), organic matter-rich (19.6 wt. % TOC) limestone from the Ghareb Formation (Upper Cretaceous) in Jordan was artificially matured by hydrous pyrolysis (200, 220 ..., 300??C; 72 h) to study the effect of progressive diagenesis and early catagenesis on the amounts and distributions of hydrocarbons, organic sulfur compounds and S-rich geomacromolecules. The use of internal standards allowed the determination of absolute amounts. With increasing thermal maturation, large amounts of alkanes and alkylthiophenes with predominantly linear carbon skeletons are generated from the kerogen. The alkylthiophene isomer distributions do not change significantly with increasing thermal maturation, indicating the applicability of alkylthiophenes as biomarkers at relatively high levels of thermal maturity. For a given carbon skeleton, the saturated hydrocarbon, alkylthiophenes and alkylbenzo[b]thiophenes are stable forms at relatively high temperatures, whereas the alkylsulfides are not stable. The large amount of alkylthiophenes produced relative to the alkanes may be explained by the large number of monosulfide links per carbon skeleton. These results are in good agreement with those obtained previously for an artificial maturation series of an immature S-rich sample from the Gessoso-solfifera Formation.An immature (Ro = 0.39%), S-rich (Sorg/C = 0.07), organic matter-rich (19.6 wt.% TOC) limestone from the Ghareb Formation (Upper Cretaceous) in Jordan was artificially matured by hydrous pyrolysis (200, 220, ..., 300??C; 72 h) to study the effect of progressive diagenesis and early catagenesis on the amounts and distributions of hydrocarbons, organic sulfur compounds and S-rich geomacromolecules.

    Failure to address women's health, including their reproductive health needs, increases health care costs and social inequity. This descriptive study assessed the reproductive and non-reproductive health status of women over 15 years old in poverty pockets in the southern region of Jordan. Two villages were selected using purposive sampling and all women in the villages were invited to participate in a "healthy family week": 259 responded to the invitation. Although 49.4% of the surveyed women were overweight or obese, only 8.5% had high blood pressure. Reproductive health concerns included the high proportions of women married at an early age (15-20 years) (76.8%), having 5+ children (43.1%) and with haemoglobin level < 12 g/dL, indicating anaemia (55.5%). Urinary tract infection was the most common health problem (29.0%). Health care providers should be sensitized to the health needs of Jordanian women in general and those living in disadvantaged areas in particular. PMID:22764426

    The carbon isotope and lipid biomarker composition of suspended particles and surface sediment was measured to examine the impact of sediment supply, redistribution and post-depositional alteration processes on organic matter cycling in the Gulf of Maine, a semi-enclosed shelf sea in the northwest Atlantic. A beam attenuation profile revealed a >50 m-thick benthic nepheloid layer (BNL) in the Jordan Basin at the time of sampling (April 2006). The relatively low radiocarbon content of suspended particulate organic carbon (POC) in the BNL indicates that up to 82% of the POC in this layer was supplied from resuspension of sediment. The concentration of alkenones normalized to POC increased with increasing depth in the water column and was highest in the surface sediment. In contrast to these markers of surface ocean photoautotrophy, the vertical profiles for the concentration and composition of short-chain (C14-C18) n-alkanoic acids provided evidence for enhanced heterotrophic processes near the top of the BNL. Suspended POC samples from two depths within the BNL exhibited marked differences in radiocarbon content and fatty acid composition, suggesting that biological activity and associated processes within the BNL are vertically heterogeneous.

    The hyper-alkaline, high-Ca(2+) springs of Maqarin, Jordan, were investigated as an analogue for various microbial processes at the extremely high pH generated by cement and concrete in some underground radioactive waste repositories. Leaching of metamorphic, cementitious phases in Maqarin has produced current, hyper-alkaline groundwater with a maximum pH of 12.9. Six consecutive expeditions were undertaken to the area during 1994-2000. The total number of microorganisms in the alkaline waters was 10(3)-10(5) cells/ml. Analysis of the 16S-ribosomal ribonucleic acid (rRNA) diversity revealed microorganisms mainly belonging to the Proteobacteria. Obvious similarities between the obtained sequences and sequences from other alkaline sites could not be found. Numerous combinations of culture media compositions were inoculated with spring, seepage and groundwaters and incubated under aerobic and anaerobic conditions with various carbon sources. Assimilation studies were performed using identical radio-labeled carbon sources. Glucose seemed to be the preferred carbon source for assimilation, followed by acetate, lactate, and leucine. The results demonstrate that microorganisms from the hyper-alkaline springs of Maqarin could grow and be metabolically active under aerobic and anaerobic hyper-alkaline conditions. However, the growth and activity found were not vigorous; instead, slow growth, low numbers, and a generally low metabolic activity were found. This suggests that microbial activity will be low during the hyper-alkaline phase of cementitious repositories. PMID:14991423

    For several decades, surface water and groundwater located in the closed Dead Sea basin experience excessive exploitation. In fifty years, the level of the terminal lake has fallen by about 30 meters and its surface shrunk by one third. The coastal zone is the one that best shows the stigma of the general environmental degradation. Among these are the sinkholes, landslides and subsidence. For years, these phenomena are relatively well documented, particularly sinkholes and subsidence. Over the past five years, field observations combined with ground deformations measurements by radar interferometric stacking techniques have shown that the intensity (size, frequency) of the collapses is increasing in the most affected part of the southern Dead Sea area. The zones of the dried up Lynch Strait, the Lisan peninsula and Ghor Al Haditha in Jordan seem the most affected. Very high resolution (0.5 to 2 m) GeoEye satellite images have shown that many sinkholes also formed below the level of the Dead Sea. The water transparency allows observations up to several meters deep. These data contribute to the validation of the models developed in connection with the deformation of the fresh/saline water interface due to an imbalance always more pronounced between the levels of the surrounding groundwaters and of the terminal lake.

    The Jordan-Wigner transformation is applied to study magnetic properties of the quantum spin-1/2 XX model on the diamond chain. Generally, the Hamiltonian of this quantum spin system can be represented in terms of spinless fermions in the presence of a gauge field and different gauge-invariant ways of assigning the spin-fermion transformation are considered. Additionally, we analyze general properties of a free-fermion chain, where all gauge terms are neglected and discuss their relevance for the quantum spin system. A consideration of interaction terms in the fermionic Hamiltonian rests upon the Hartree-Fock procedure after fixing the appropriate gauge. Finally, we discuss the magnetic properties of this quantum spin model at zero as well as non-zero temperatures and analyze the validity of the approximation used through a comparison with the results of the exact diagonalization method for finite (up to 36 spins) chains. Besides the m = 1/3 plateau the most prominent feature of the magnetization curve is a jump at intermediate field present for certain values of the frustrating vertical bond.

    Dust storms in the Middle East are common during spring. Some of these storms are massive and carry a large amount of dust from faraway regions, which pose health and pollution risks. The huge dust storm event occurred in early May, 2012 was investigated for its radioactive content using gamma ray spectroscopy. Dust samples were collected from Northern Jordan and it was found that the storm carried a large amount of both artificial and natural radioactivity. The average activity concentration of fallout (137)Cs was 17.0 Bq/kg which is larger than that found in soil (2.3 Bq/kg), and this enrichment is attributed to particle size effects. (7)Be which is of atmospheric origin and has a relatively short half-life, was detected in dust with relatively large activity concentrations, as it would be expected, with an average of 2860 Bq/kg, but it was not detected in soil. Despite the large activity concentration of (7)Be, dose assessment showed that it does not contribute significantly to the effective dose through inhalation. The concentrations of the primodial nuclides (40)K, (232)Th and (238)U were 547, 30.0 and 49.3 Bq/kg, respectively. With the exception of (40)K, these were comparable to what was found in soil.

    Aims: This study aimed to describe nurses’ perceptions of spirituality and spiritual care in Jordan, and to investigate the relationship between their perceptions and their demographic variables. Methods: The study used a cross-sectional descriptive design and recruited a convenience sample of 408 Jordanian registered nurses to complete the spiritual care giving scale. Results: The findings of the study demonstrated that most of the participating nurses had a high level of spirituality and spiritual care perception. Significant differences were found between male and female nurses’ perceptions of spirituality and spiritual care (P < 0.05); previous attendance of courses on spiritual care also made a significant difference to perceptions (P < 0.05). Conclusions: The research findings suggest that, Jordanian nurses’ gender made a difference in their perceptions of spirituality and spiritual care. They had satisfactory levels of perception of spirituality and spiritual care. Moreover, spiritual care courses appeared to have a positive impact on their perception of spirituality and spiritual care. Enhancing nursing care by integrating standardized spiritual care into the current nursing care, training, and education should also be emphasized. PMID:26962280

    A field survey was carried out to record plant species climbed by Ephedra alte in certain parts of Jordan during 2008–2010. Forty species of shrubs, ornamental, fruit, and forest trees belonging to 24 plant families suffered from the climbing habit of E. alte. Growth of host plants was adversely affected by E. alte growth that extended over their vegetation. In addition to its possible competition for water and nutrients, the extensive growth it forms over host species prevents photosynthesis, smothers growth and makes plants die underneath the extensive cover. However, E. alte did not climb all plant species, indicating a host preference range. Damaged fruit trees included Amygdalus communis, Citrus aurantifolia, Ficus carica, Olea europaea, Opuntia ficus-indica, and Punica granatum. Forestry species that were adversely affected included Acacia cyanophylla, Ceratonia siliqua, Crataegus azarolus, Cupressus sempervirens, Pinus halepensis, Pistacia atlantica, Pistacia palaestina, Quercus coccifera, Quercus infectoria, Retama raetam, Rhamnus palaestina, Rhus tripartita, and Zizyphus spina-christi. Woody ornamentals attacked were Ailanthus altissima, Hedera helix, Jasminum fruticans, Jasminum grandiflorum, Nerium oleander, and Pyracantha coccinea. Results indicated that E. alte is a strong competitive for light and can completely smother plants supporting its growth. A. communis, F. carica, R. palaestina, and C. azarolus were most frequently attacked. PMID:22645486

    This study was conducted to investigate the prevalence of intimate partner violence (IPV) among a sample of women visiting health care centers in Palestine refugee camps in Jordan. We found that different types of IPV, including physical, emotional, sexual, economic, and control behaviors by the partners were experienced by the participants. This study was among a number of studies that investigated this phenomenon in residents of Palestinian camps. It adds to existing studies in this field, however, as it focuses on the prevalence of the top five types of IPV in these women. Co-occurrence of IPV, that is, experiencing two or more types of partner violence at the same time, was noticed in these women. Experiencing control by one's partner and the presence of different attitudes between men and women toward the use of violence were factors contributing to the occurrence of this phenomenon in these women. National efforts aiming at breaking the cycle of violence should be fostered through media and public awareness campaigns. Changing people's attitudes concerning men's use and women's acceptance of violence should be the aim of these efforts. PMID:25255940

    Storm-water harvesting and storage via managed aquifer recharge (MAR) is a promising approach to combat water scarcity in semi-arid regions, but poses a challenge for karst aquifers and regions with highly variable water availability. The infiltration of low-mineralized surface water and its impact on highly mineralized groundwater of a karst aquifer was investigated at Wala reservoir in Jordan over a period of approximately 10 years. The results show significant groundwater-level rise in a wellfield, in response to the yearly average infiltration of about 6.7 million m3. This corresponds to about 60 % of the yearly average abstraction of about 11.7 million m3, confirmed by mixing calculations with tritium. A decreasing trend in infiltration due to sedimentation is observed. Mean groundwater residence times of several thousand years, derived from carbon-14 dating, indicate a large storage capacity of the aquifer. The heterogeneous distribution of the residence times is caused by strong groundwater withdrawals and artificial recharge along with karst-specific aquifer characteristics. Temporal groundwater salinity fluctuations in the wellfield are observed after the first MAR infiltration. Enhanced groundwater flow along the wadi course was demonstrated, which is an important aspect with regards to future MAR projects in similar wadis of the region.

    Treatment of non-communicable diseases such as cancer in refugees is neglected in low-income and middle-income countries, but is of increasing importance because the number of refugees is growing. The UNHCR, through exceptional care committees (ECCs), has developed standard operating procedures to address expensive medical treatment for refugees in host countries, to decide on eligibility and amount of payment. We present data from funding applications for cancer treatments for refugees in Jordan between 2010 and 2012, and in Syria between 2009 and 2011. Cancer in refugees causes a substantial burden on the health systems of the host countries. Recommendations to improve prevention and treatment include improvement of health systems through standard operating procedures and innovative financing schemes, balance of primary and emergency care with expensive referral care, development of electronic cancer registries, and securement of sustainable funding sources. Analysis of cancer care in low-income refugee settings, particularly in sub-Saharan Africa, is needed to inform future responses. PMID:24872112

    After decades of paleointensity research, it is still not fully understood how fast can field intensity change. Direct measurements of field intensity that go back to the 1830s show relatively small changes with rather smooth behavior over decadal timescales. In contrast, recent archaeomagnetic studies have revealed periods with significant intensity variations termed "archaeomagnetic jerks" (Gallet et al., 2003) and "spikes" (Ben-Yosef et al., 2009). This apparent inconsistency suggests that temporal variations of the geomagnetic field intensity over the past two centuries have been relatively small compared to earlier periods. To address this question we have investigated several ancient slag mounds in Jordan, Israel, and Cyprus. The mounds are multi-layered sequences of slag and charcoal that rapidly accumulated near ancient copper smelting sites as long as copper was produced in the nearby sites. The chronologies of the slag mounds were modeled using radiocarbon dates of short-lived material. Paleointensities were obtained using Thellier-type IZZI experiments with additional anisotropy, cooling rate, and non-linear TRM assessments. The overall data indicate that some periods are characterized with extremely high variation rate, while other periods seem quieter. In this presentation we review different aspects of our working methodology: field sampling, wood identification and radiocarbon analysis, age modeling, magnetic petrology, magnetic microscopy, and finally, paleointensity and data analysis. We present new recently published data from two Cypriot slag mounds, and discuss the overall archaeomagnetic findings in the context of high precision geomagnetic models of the past 170 years.

    Factors associated with antibiotic use, resistance and safety have been well recognized worldwide in the literature. Nevertheless, only few studies have been conducted in Jordan in this area. The aim of this study was to assess knowledge, behavior and attitude toward antibiotics use among adult Jordanians. The study represents a cross sectional survey using an interviewer administered questionnaire. Data collected from a random sample of 1141 adult Jordanians, recruited at different settings, regarding their knowledge about the effectiveness of, resistance toward, and self medications with antibiotics against bacterial, viral and parasitic diseases. 67.1% believed that antibiotics treat common cold and cough. 28.1% misused antibiotics as analgesics. 11.9% of females showed inadequate knowledge about the safe use of antibiotics during pregnancy and nursing. 28.5% kept antibiotics at home for emergency use and 55.6% use them as prophylaxis against infections. 49.0% use left-over antibiotics without physicians' consultation while 51.8% use antibiotics based on a relative advice. 22.9% of physicians prescribe antibiotics over the phone and >50.0% routinely prescribe antibiotics to treat common cold symptoms. Our findings indicated that young adults showed unsatisfactory knowledge of proper antibiotic use. Therefore, there is an urge for educational programs using all media means. PMID:23960783

  4. The domestication of water: water management in the ancient world and its prehistoric origins in the Jordan Valley.

    The ancient civilizations were dependent upon sophisticated systems of water management. The hydraulic engineering works found in ancient Angkor (ninth to thirteenth century AD), the Aztec city of Tenochtitlan (thirteenth to fifteenth century AD), Byzantine Constantinople (fourth to sixth century AD) and Nabatean Petra (sixth century BC to AD 106) are particularly striking because each of these is in localities of the world that are once again facing a water crisis. Without water management, such ancient cities would never have emerged, nor would the urban communities and towns from which they developed. Indeed, the 'domestication' of water marked a key turning point in the cultural trajectory of each region of the world where state societies developed. This is illustrated by examining the prehistory of water management in the Jordan Valley, identifying the later Neolithic (approx. 8300-6500 years ago) as a key period when significant investment in water management occurred, laying the foundation for the development of the first urban communities of the Early Bronze Age.

    Mark-recapture studies indicated that a pulsed-DC electrical barrier set to a 2-ms pulse width and 10 pulses/s completely blocked the spawning migration of sea lampreys Petromyzon marinus in the Jordan River, Michigan. Capture efficiency of fyke nets averaged 24% for four groups, about 300 tagged sea lampreys each, released upstream of the barrier; no unmarked sea lampreys and none of the 1,194 sea lampreys tagged and released downstream of the barrier were captured in the fyke nets while the barrier was energized. At a lower pulsator setting (1-ms pulse width; 10 pulses/s), 1 of 900 sea lampreys released below the barrier was recaptured in the nets. Sea lampreys from downstream were captured in the fyke nets after the barrier was de-energized, indicating that the barrier should remain in operation later than mid-July. Both sea lampreys and teleosts exposed to the electrical field were stunned but exhibited no apparent damage at either barrier setting. The pulsed-DC electrical barrier should help reduce the use of chemical lampricides for controlling sea lampreys in some Great Lakes streams and would be particularly suited for streams where even the smallest low-head barrier would create an unacceptably large impoundment.

  6. Possible impacts of anthropogenic aerosols on water resources of the Jordan River and the Sea of Galilee

    Insights are provided to the hitherto unexplained decreasing trends in the available water for consumption from the Sea of Galilee and in the outflow of the main springs of the Jordan River with respect to the nearby rainfall. The loss of available water of about 110 million m3 yr-1 (about 6.5% of the national water consumption in Israel) is shown to be caused by a decreasing trend in the factor of precipitation enhancement by uplifting on topographic barriers. Previous studies, reviewed here, show that the most probable cause of this decreasing trend is an increasing trend in the concentrations of submicron air pollution particles during the last half century. These particles slow down the conversion of cloud drops into raindrops and snow flakes, thus decreasing precipitation from short-lived clouds such as form in moist air that crosses topographic barriers. This decreasing trend was partially mitigated by cloud seeding for rain enhancement, but apparently, the air pollution dominated and caused a net loss of orographic precipitation. A large portion of the water resources in this semiarid part of the world results from orographic precipitation. Therefore this is an issue with major economic and societal implications, not only to the study area but to many other densely populated parts of the world where the livelihood of the inhabitants depends on water resulting from orographic precipitation, which might be compromised by the air pollution produced by the very people who depend on that water.

  7. Climate change and archaeological site distribution during the past four millennia in northern Jordan utilizing oxygen isotope analysis of human tooth enamel and geographic information system

    The enamels of one hundred and ninety two teeth were analyzed for their oxygen isotopic composition from five archaeological sites in northern Jordan (Ya'amoun, Pella, Yasieleh, Sa'ad and Waqqas) to reconstruct the climate from the Middle Bronze Age II (1800--1500 BCE) to the Late Byzantine Period (491--640 CE). Results showed that the Middle Bronze Age II delta 18O values were the highest indicating warmer and drier climate conditions. The Late Bronze Age II and the Iron Age I/II experienced more favorable climate conditions. The Early Byzantine period delta18O values indicate wetter conditions compared to the Late Byzantine period but the latter was wetter than the Middle Bronze Age II. The geographic distribution of the archaeological sites in Jordan was affected by climate that changed over the prehistory of the country (from the Paleolithic to the Ottoman Period). Archaeological sites decreased in number during dry periods like the Middle Bronze Age II but increased during wet periods like the Roman one. Proximity to water sources was favored during the various cultural periods, where the northwestern and the mid-western areas witnessed dense occupation. On the other hand, areas that presently receive less than 200mm annual rainfall were not favored even during the wet periods. There were major climate events that overran the whole Mediterranean region during the Holocene, where Jordan was subject to them as well. These climatic events (prolonged droughts and/or insufficient precipitation) were identified using Bryson's archaeoclimate model that simulates the amount of precipitation, evapotranspiration and temperature during the last 12,000 years. These climate events coincided with the collapse of many societies in the Levant, such as the Middle Bronze Age societies of Mesopotamian cities.

    Between June and September 2013, sera from 11 dromedary camels, 150 goats, 126 sheep and 91 cows were collected in Jordan, where the first human Middle-East respiratory syndrome (MERS) cluster appeared in 2012. All sera were tested for MERS-coronavirus (MERS-CoV) specific antibodies by protein microarray with confirmation by virus neutralisation. Neutralising antibodies were found in all camel sera while sera from goats and cattle tested negative. Although six sheep sera reacted with MERS-CoV antigen, neutralising antibodies were not detected. PMID:24342516

  9. New structural/tectonical model and its implication on hydrological thinking and groundwater management - the Lake Tiberias, Jordan Rift Valley

    Lake Tiberias is a fresh water lake located at the Kinneret basin which is approximately 30 km long and 10 km wide. It comprises a link in the chain of pull-apart basins that characterizes the structure of the conspicuous Jordan Rift Valley (JRV). The basin surface is about 200 m below mean sea level (msl) and basin-fill attains a thickness of up to 8 km. Until recently, studies focused mainly on the upper strata of basin fill. Consequently, a complete three dimensional geological model, including clear view of the tectonic framework at the Kinneret Basin was incomplete. This situation imposes great difficulty in understanding the local hydrological system and as consequence enforce constrains on groundwater management of the regional aquifers that flows towards the lake. A recently proposed structural/tectonical model (Inbar, 2012) enables revaluation of several geohydrological aspects at Sea of Galilee and its surroundings and a new hydrological model based on those findings aims to clarify those aspects with relation to groundwater management. The deep-seated stratigraphical units were seismically studied at the Kinnarot Valley (southern part of Kinneret basin) where sufficient information is available (Inbar, 2012). This study shows the subsidence and northwestward tilting of the basin floor (pre-rift formations) and the flow of thick Late Miocene salt accumulation accordingly. Furthermore, shallower seismic data, collected at the lake itself, shows a suspected salt dome close to the western boundary fault of the basin (Resnikov et al., 2004). Salt flow is now suggested to be a substantial factor in the tectonic play. At the lake surroundings there are several springs and boreholes where brine immerges from an estimated depth of about 2-3 kilometers. Significant differences in brine characteristics raised questions regarding the location of brine traps, flow mechanism and the mixture process between the fresh water and the brine. However, the effect of the juxtaposing salt rock to the hydrological system was overlooked. Recent study reported an anomaly in groundwater chemistry at the western shore, indicating a possible contribution of halite dissolution into the ascending brine (Möller et al., 2011). This correlates to the results of the salt tectonic model and the suspected salt diapir above mentioned. Moreover, Arbel-1 borehole (drilled at 2003 at the same area) showed rapid salinity increase during pumping. Today the well is shut off. Based on the above findings, a numerical model is built. The studied profile crosses the rift from the Galilee at the west to the Golan and Ajlun at the east reaching a depth of 6 kilometers. The model indicates the possible brine flow paths across the rift and their interaction with fresh water aquifers and lake springs. References Inbar, N.

    Amman-Zerqa Basin (AZB) is the second largest groundwater basin in Jordan with the highest abstraction rate, where more than 28% of total abstractions in Jordan come from this basin. In view of the extensive reliance on this basin, contamination of AZB groundwater became an alarming issue. This paper develops a Modified DRASTIC model by combining the generic DRASTIC model with land use activities and lineament density for the study area with a new model map that evaluates pollution potential of groundwater resources in AZB to various types of pollution. It involves the comparison of modified DRASTIC model that integrates nitrate loading along with other DRASTIC parameters. In addition, parameters to account for differences in land use and lineaments density were added to the DRASTIC model to reflect their influences on groundwater pollution potential. The DRASTIC model showed only 0.08% (3 km2) of the AZB is situated in the high vulnerability area and about 30% of the basin is located in the moderately vulnerable zone (mainly in central basin). After modifying the DRASTIC to account for lineament density, about 87% of the area was classified as having low pollution potential and no vulnerability class accounts for about 5.01% of the AZB area. The moderately susceptible zone covers 7.83% of the basin's total area and the high vulnerability area constitutes 0.13%. The vulnerability map based on land use revealed that about 71% of the study area has low pollution potential and no vulnerability area accounts for about 0.55%, whereas moderate pollution potential zone covers an area of 28.35% and the high vulnerability class constitutes 0.11% of AZB. The final DRASTIC model which combined all DRASTIC models shows that slightly more than 89% of the study area falls under low pollution risk and about 6% is considered areas with no vulnerability. The moderate pollution risk potential covers an area of about 4% of AZB and the high vulnerability class constitutes 0.21% of the basin. The results also showed that an area of about 1761 km2 of bare soils is of low vulnerability, whereas about 28 km2 is moderately vulnerable. For agriculture and the urban sector, approximately 1472 km2 are located within the low vulnerability zone and about 144 km2 are moderately vulnerable, which together account for about 8% of the total agriculture and urban area. These areas are contaminated with human activities, particularly from the agriculture. Management of land use must be considered when changing human or agricultural activity patterns in the study area, to reduce groundwater vulnerability in the basin. The results also showed that the wells with the highest nitrate levels (81-107 mg/l) were located in high vulnerable areas and are attributed to leakage from old sewage water.

    The residues of polynuclear aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), chlorinated benzenes (CBs) and phenols were investigated for soil, wastewater, groundwater and plants. The uptake concentration of these compounds was comparatively determined using various plant types: Zea mays L., Helianthus annus L., Capsicum annum L., Abelmoschus esculentus L., Solanum melongena L. and Lycopersicon esculentum L. which were grown in a pilot site established at Mutah University wastewater treatment plant, Jordan. Soil, wastewater, groundwater and various plant parts (roots, leaves and fruits) samples were extracted in duplicate, cleaned up by open-column chromatography and analyzed by a multi-residue analytical methods using gas chromatography equipped with either mass selective detector (GC/MS), electron capture detector (GC/ECD), or flame ionization detector (FID). Environmentally relevant concentrations of targeted compounds were detected for wastewater much higher than for groundwater. The overall distribution profiles of PAHs and PCBs appeared similar for groundwater and wastewater indicating common potential pollution sources. The concentrations of PAHs, PCBs and phenols for different soils ranged from 169.34 to 673.20 microg kg(-1), 0.04 to 73.86 microg kg(-1) and 73.83 to 8724.42 microg kg(-1), respectively. However, much lower concentrations were detected for reference soil. CBs were detected in very low concentrations. Furthermore, it was found that different plants have different uptake and translocation behavior. As a consequence, there are some difficulties in evaluating the translocation of PAHs, CBs, PCBs and phenols from soil-roots-plant system. The uptake concentrations of various compounds from soil, in which plants grown, were dependent on plant variety and plant part, and they showed different uptake concentrations. Among the different plant parts, roots were found to be the most contaminated and fruits the least contaminated. PMID:18471853

    Modeling groundwater properties is an important tool by means of which water resources management can judge whether these properties are within the safe limits or not. This is usually done regularly and in the aftermath of crises that are expected to reflect negatively on groundwater properties, as occurred in Jordan due to crises in neighboring countries. In this study, specific capacity and salinity of groundwater of B2/A7 aquifer in Amman Zarqa Basin were evaluated to figure out the effect of population increase in this basin as a result of refugee flux from neighboring countries to this heavily populated basin after Gulf crises 1990 and 2003. Both properties were found to exhibit a three-parameter lognormal distribution. The empirically calculated ? parameter of this distribution mounted up to 0.39 m(3)/h/min for specific capacity and 238 ppm for salinity. This parameter is suggested to account for the global changes that took place all over the basin during the entire period of observation and not for local changes at every well or at certain localities in the basin. It can be considered as an exploratory result of data analysis. Formal and implicit evaluation followed this step using structural analysis and construction of experimental semivariograms that represent the spatial variability of both properties. The adopted semivariograms were then used to construct maps to illustrate the spatial variability of the properties under consideration using kriging interpolation techniques. Semivariograms show that specific capacity and salinity values are spatially dependent within 14,529 and 16,309 m, respectively. Specific capacity semivariogram exhibit a nugget effect on a small scale (324 m). This can be attributed to heterogeneity or inadequacies in measurement. Specific capacity and salinity maps show that the major changes exhibit a northwest southeast trend, near As-Samra Wastewater Treatment Plant. The results of this study suggest proper management practices. PMID:26687089

    Background: Coordinated high-impact interventions and community-level changes in smoking behaviour norms effectively reduced prevalence of smoking among youth in many developed countries. Smoking trends among Jordanian adolescents are likely different than their Western counterparts and must be understood in the context of their daily lives to tailor interventions specifically for adolescents in this setting. Methods: Between 2008 and 2011, a school-based longitudinal study was conducted in Irbid, Jordan. All seventh-grade students in 19 randomly selected schools (of 60) were surveyed annually for 4 years. Outcomes of interest were time trends in smoking behaviour, age at initiation and change in frequency of smoking. Results: Among 1781 participants, baseline prevalence of current smoking (cigarettes or waterpipe) for boys was 22.9% and 8.7% for girls. Prevalence of ever-smoking and current any smoking, cigarette smoking, waterpipe smoking and dual cigarette/waterpipe smoking was significantly higher in boys than girls each year (P < 0.001). Smoking prevalence increased every year after year 2 for current smoking (P < 0.05) across all methods (any, cigarette, waterpipe and dual). At all time points for both boys and girls, prevalence of waterpipe smoking was higher than that of cigarette smoking (P < 0.001). Conclusion: This study shows intensive smoking patterns at early ages among Jordanian youth in Irbid, characterized by a predominance of waterpipe smoking and steeper age-related increase in cigarette smoking. It also points to the possibility of waterpipe being the favourite method for introducing youth to tobacco, as well as being a vehicle for tobacco dependence and cigarette smoking. PMID:24078649

    The transition from mobile to sedentary life was one of the greatest social challenges of the human past. Yet little is known about the impact of this fundamental change on social interactions amongst early Neolithic communities, which are best recorded in the Near East. The importance of social processes associated with these economic and ecological changes has long been underestimated. However, ethnographic observations demonstrate that generalized reciprocity – such as open access to resources and land – had to be reduced to a circumscribed group before regular farming and herding could be successfully established. Our aim was thus to investigate the role of familial relationships as one possible factor within this process of segregation as recorded directly in the skeletal remains, rather than based on hypothetical correlations such as house types and social units. Here we present the revealing results of the systematically recorded epigenetic characteristics of teeth and skulls of the late Pre-Pottery Neolithic community of Basta in Southern Jordan (Figure S1). Additionally, mobility was reconstructed via a systematic strontium (Sr) isotope analysis of tooth enamel of the Basta individuals. The frequency of congenitally missing maxillary lateral incisors in the 9,000-year-old community of Basta is exceptionally high (35.7%). Genetic studies and a worldwide comparison of the general rate of this dental anomaly in modern and historic populations show that the enhanced frequency can only be explained by close familial relationships akin to endogamy. This is supported by strontium isotope analyses of teeth, indicating a local origin of almost all investigated individuals. Yet, the accompanying archaeological finds document far-reaching economic exchange with neighboring groups and a population density hitherto unparalleled. We thus conclude that endogamy in the early Neolithic village of Basta was not due to geographic isolation or a lack of exogamous mating partners but a socio-cultural choice. PMID:23776517

    In the framework of a three years' time period of a PhD thesis it is luck to catch the "right" rain events for good general erosion approximations. Methods that (i) cover longer time periods, (ii) are not confined to constructed boundaries, and finally (iii) include all possible erosion processes are crucial for good average estimates of sediment yields from different landscapes. The aim of the study was to get a first understanding of erosion processes and sediment yields in a Mediterranean to semi-arid catchment in NW Jordan, wherefore different measurement methods were tested in the predominant landscape units: olive orchards (27%), fields (14%) and natural shrubs on steep slopes (~30%). One of the applied methods was the measurement of topographic olive mounds within 7 orchards with an average size of 800 m2 in synergy with tree-coring and age estimation of the orchards. Furthermore the OSL dating of deposited sediments in two roman cisterns adjacent to fields was conducted and the 9 erosion pin fields, each about 200m2 large, were installed on steep slopes with natural vegetation. The methods cover different time scales from 560 years for the fields, an average of 32 years for the olive orchards and up to two rainy seasons for the erosion pin fields. Results show that olive orchards on steep slopes (>10%) have the highest erosion potential in the region with 95±8 t ha-1year-1 followed by natural vegetated slopes with 37±4 t ha-1year-1 of dislocated material and fields with 1.22±0.06 t ha-1year-1 sediment yield. These spatially constrained outcomes are supported by geochemical sediment fingerprint results of lake sediments from the catchment and will be discussed in regard to the basic assumption that underlie the principle of measurement and the limitations of the methods.

    Contamination of groundwater from point and nonpoint sources is a recognized problem in the karst area of southeastern Minnesota. The US Geological Survey, in cooperation with the Minnesota Department of Natural Resources and the Legislative Commission on Minnesota Resources, began a study in October 1987 to improve the understanding of local groundwater flow through karst terrain in southeastern Minnesota. The objectives of the study are to: (1) describe the orientations of systematic rock fractures and solution channels of the Prairie du Chien Group of Ordovician-age carbonate rocks in southeastern Minnesota, and, if possible, to define the principal and minor axes of these orientations; and (2) evaluate the effect of fractures and solution channels in the Prairie due Chien Group on the local flow of groundwater. Groundwater in the Upper Carbonate aquifer regionally flows toward the periphery of the aquifer and locally flows into streams and bedrock valleys. The hydraulic gradient in this aquifer generally is greatest near areas of groundwater seepage to streams. Regional groundwater flow in the Prairie du Chien-Jordan aquifer generally is to the south and east in much of Fillmore and Houston Counties and in the southern parts of Olmsted and Winona Counties. Groundwater seepage to selected streams was evaluated by current-meter measurements of downstream gains or losses of stream-flow and by an experimental approach based on radon activity in streams. The activity of radon in groundwater ranges from two to four orders of magnitude greater than the activity in surface water; therefore, groundwater seepage to streams generally increases the in-stream radon activity. 6 refs., 2 figs.

    Wet atmospheric samples were collected from different locations in the southern region of Jordan during a 5-year period (October 2006 to May 2011). All samples were analyzed for pH, EC, major ions (Ca(2+), Mg(2+), Na(+), K(+), HCO3(-), Cl(-), NO3(-), and SO4(2-)), and trace metals (Fe(2+), Al(3+), Cu(2+), Pb(2+), and Zn(2+)). The highest ion concentrations were observed during the beginning of the rainfall events because large amounts of dust accumulated in the atmosphere during dry periods and were scavenged by rain. The rainwater in the study area is characterized by low salinity and neutral pH. The major ions found in rainwater followed the order of HCO3? > ?Cl(-)?> ?SO4(2-) and Ca(2+)?>? Na(+) > Mg(2+) > NH4(+) > K(+). Trace metals were identified to be of anthropogenic origin resulting from cement and phosphate mining activities located within the investigated area and from heating activities during the cold period of the year (January to April). The wet precipitation chemistry was analyzed using factor component analysis for possible sources of the measured species. Factor analysis (principal component analysis) was used to assess the relationships between the concentrations of the studied ions and their sources. Factor 1 represents the contribution of ions from local anthropogenic activities, factor 2 represents the contribution of ions from natural sources, and factor 3 suggests biomass burning and anthropogenic source. Overall, the results revealed that rainwater chemistry is strongly influenced by local anthropogenic sources rather than natural and marine sources, which is in a good agreement with the results obtained by other studies conducted in similar sites around the world.

    This study was conducted to isolate Salmonella Enteritidis from poultry samples and compare their virulence and antibiotic resistance profiles to S. Enteritidis isolated from outbreaks in northern Jordan. Two hundred presumptive isolates were obtained from 302 raw poultry samples and were subjected to further analysis and confirmation. A phylogenic tree based on 16S rRNA sequencing was constructed and selected isolates representing each cluster were further studied for their virulence in normal adult Swiss white mice. The most virulent strains were isolated from poultry samples and had an LD50 of 1.55 × 105 CFU, while some of the outbreak isolates were avirulent in mice. Antibiotic resistance profiling revealed that the isolates were resistant to seven of eight antibiotics screened with each isolate resistant to multiple antibiotics (from two to six). Of the poultry isolates, 100%, 88.9%, 77.8%, 66.7%, and 50% showed resistance to nalidixic acid, ciprofloxacin, ampicillin, cephalothin, and cefoperazone, respectively. Two outbreak isolates were sensitive to all tested antibiotics, while 71.4% were resistant to cefoperazone and only 28.6% showed resistance to nalidixic acid. Salmonella outbreak isolates were genetically related to poultry isolates as inferred from the 16S rRNA sequencing, yet were phenotypically different. Although outbreak strains were similar to poultry isolates, when tested in the mouse model, some of the outbreak isolates were highly virulent while others were avirulent. This might be due to a variation in susceptibility of the mouse to different S. Enteritidis isolates. PMID:24780883

    The transition from mobile to sedentary life was one of the greatest social challenges of the human past. Yet little is known about the impact of this fundamental change on social interactions amongst early Neolithic communities, which are best recorded in the Near East. The importance of social processes associated with these economic and ecological changes has long been underestimated. However, ethnographic observations demonstrate that generalized reciprocity - such as open access to resources and land - had to be reduced to a circumscribed group before regular farming and herding could be successfully established. Our aim was thus to investigate the role of familial relationships as one possible factor within this process of segregation as recorded directly in the skeletal remains, rather than based on hypothetical correlations such as house types and social units.

  2. Spatial variability of environmental isotope and chemical content of precipitation in Jordan and evidence of slight change in climate

    The spatial variability of the ?18O and ?D compositions of rain is attributed to variations in amount of precipitation (PPT), altitude effect, and air masses originating from different sources. Air masses that enter the area passing the Mediterranean Sea result in higher d-excess. The cold and dry continental air masses originating from the European continent come in contact with the warm Mediterranean Sea water, resulting in rapid evaporation and large scale convergence. The low d-excess value is less than 16 ‰ and associated with air masses that cross over the North African continent and controlled by a local orographic effect. The change in isotopic composition of ?18O in PPT with altitude is -0.15 ‰ per 100 m. A statistical model confirms that a slight decrease in annual average precipitation has occurred since 1988 and attributed to a minor change in climate. The current level of tritium in rain corresponds to the average level of tritium in the atmosphere. Rabba station recorded a twofold higher tritium concentration in 1995 than the other stations, which may be from leakage from a nuclear station in Israel. The chemistry of rainwater demonstrates a wide range of salinity (100-600 mg/l). The lowest solute concentrations are found at high elevations, and the highest solute concentrations are found in the eastern desert and the Jordan Rift valley. The salinity of rain is affected by desert dust, aerosols, amounts of PPT, and the direction of rain fronts. The aerosols and windblown soil are the most prevailing as the country is confined between three seas and the outcrop surficial geology is mainly sedimentary rocks.

    Research studies aimed at advancing cancer prevention, diagnosis, and treatment depend on a number of key resources, including a ready supply of high-quality annotated biospecimens from diverse ethnic populations that can be used to test new drugs, assess the validity of prognostic biomarkers, and develop tailor-made therapies. In November 2011, KHCCBIO was established at the King Hussein Cancer Center (KHCC) with the support of Seventh Framework Programme (FP7) funding from the European Union (khccbio.khcc.jo). KHCCBIO was developed for the purpose of achieving an ISO accredited cancer biobank through the collection, processing, and preservation of high-quality, clinically annotated biospecimens from consenting cancer patients, making it the first cancer biobank of its kind in Jordan. The establishment of a state-of-the-art, standardized biospecimen repository of matched normal and lung tumor tissue, in addition to blood components such as serum, plasma, and white blood cells, was achieved through the support and experience of its European partners, Trinity College Dublin, Biostór Ireland, and accelopment AG. To date, KHCCBIO along with its partners, have worked closely in establishing an ISO Quality Management System (QMS) under which the biobank will operate. A Quality Policy Manual, Validation, and Training plan have been developed in addition to the development of standard operating procedures (SOPs) for consenting policies on ethical issues, data privacy, confidentiality, and biobanking bylaws. SOPs have also been drafted according to best international practices and implemented for the donation, procurement, processing, testing, preservation, storage, and distribution of tissues and blood samples from lung cancer patients, which will form the basis for the procurement of other cancer types. KHCCBIO will be the first ISO accredited cancer biobank from a diverse ethnic Middle Eastern and North African population. It will provide a unique and valuable resource of high-quality human biospecimens and anonymized clinicopathological data to the cancer research communities world-wide. PMID:24620764

    Indoor and soil radon concentrations were measured in the villages of Ayn-Jana, Ishtafena, Samta and Umm-Yanabe' in the district of Ajloun, Jordan. Several factors that are strongly related to the radon concentrations are considered whether in soil such as its type or indoors such as room occupation type, floor level and building materials. In the village of Ayn-Jana, our results showed that the average radon concentration decreases gradually as the floor level increases. The highest concentration was found to be in the ground floor (35.5 ± 5.0 Bqm(-3)) and the lowest was in the second floor (22.9 ± 3.2 Bqm(-3)). Regarding the effect of ventilation rate in the same village, storage rooms revealed the highest concentration (38.8 ± 5.4 Bqm(-3)) while the lowest concentration was in living rooms (33.8 ± 4.4 Bqm(-3)). In the four villages, it was found that the highest radon concentration was in the dwellings made of clay (45.7 ± 6.7 Bqm(-3)) and the lowest was in dwellings made of brick (33.9 ± 6.4 Bqm(-3)). In general, the average indoor radon concentration in these villages was 36.3 ± 2.3 Bqm(-3) and it corresponds to an average effective dose rate of 0.92 ± 0.06 mSvyr(-1). These indoor radon concentrations as well as the annual effective dose are below the action level recommended by ICRP. The average radon concentration in soil of these villages was about 2.55 ± 0.20 kBqm(-3), and it ranges from 2.08 ± 0.12 kBqm(-3) in the village of Ayn-Jana to 3.62 ± 0.13 kBqm(-3) in the village of Ishtafena.

    In the Middle East, the major sources of lead exposure have been leaded gasoline, lead-contaminated flour from traditional stone mills, focal exposures from small battery plants and smelters, and kohl (blue color) in cosmetics. In 1998–2000, we measured blood lead (PbB) levels in children 2–6 years of age in Israel, Jordan, and the Palestinian Authority (n = 1478), using a fingerstick method. Mean (peak; percentage > 10 ?g/dL) PbB levels in Israel (n = 317), the West Bank (n = 344), Jordan (n = 382), and Gaza (n = 435) were 3.2 ?g/dL (18.2; 2.2%), 4.2 ?g/dL (25.7; 5.2%), 3.2 ?g/dL (39.3; < 1%), and 8.6 ?g/dL (> 80.0; 17.2%), respectively. High levels in Gaza were all among children living near a battery factory. The findings, taken together with data on time trends in lead emissions and in PbB in children in previous years, indicate the benefits from phasing out of leaded gasoline but state the case for further reductions and investigation of hot spots. The project demonstrated the benefits of regional cooperation in planning and carrying out a jointly designed project. PMID:16759995

    Background: The antiproliferative activity of Salvia species grown in Jordan has not been fully evaluated yet. The aim of this work was to study the antiproliferative activity of crude ethanol extracts from nine Salvia species grown in Jordan against a panel of breast cancer cell lines. Material and Methods: Cytotoxic activity was evaluated in human tumor models of breast cancer; MCF-7, T47D, ZR-75-1, and BT 474 by the sulforhodamine B assay. In addition, the extracts were evaluated using a non-transformed cell line (Vero) and normal fibroblast cells in order to demonstrate their selectivity and safety. Results: From the nice ethanol extracts under investigation, those of S. dominica and S. fruticosa showed an inhibitory concentration of 50% of cells (IC50) in concentrations less than 30?g/mL against the four cell lines under investigation. S. syriaca and S. hormium showed an IC50 below 30?g/ml for two out of the four cell lines. S. fruticosa, S. hormium and S. syriaca showed selectivity in their antiproliferative activity against estrogen receptor positive cell lines with minimal toxicity against normal human periodontal fibroblasts. Phytochemical screening using thin layer chromatography indicated the presence of terpenoids, flavonoids and coumarins in all examined extracts. Conclusion: Three of the plant extracts under investigation exhibited antiproliferative activity against breast cancer cells and were shown to be safe and selective. These could be considered as a potential source for novel anticancer therapy. PMID:24082637

    A new approach for paleostress analysis, using the nine-dimensional space fault slip inversion method, was performed in the southeastern flank of the Jordan-Dead Sea Fault. Five major tectonic episodes with different kinematics were successfully detected from the inversion of a new fault slip data, which thereby caused reactivation of inherited crustal structures and established new ones. These episodes prevailed since Late Cretaceous times, and their chronological constraints were established essentially from the stratigraphic ages of the affected rocks and the crosscutting relationships of successive striae locally observed on the fault planes. During the Late Cretaceous to late Eocene, the area was under a compressional/strike-slip stress regime with a ~E-W trending σ1. At Oligocene, a strike-slip stress regime with NW-SE striking σ1 occurred. Both compression regimes correspond to the so-called Syrian Arc Deformation that gave rise to distinctive folds in Jordan and its surrounding areas. An extension with ~N-S to NE-SW trending σ3 followed the late Oligocene compression event and took place during Miocene time, most probably linked to the opening of the Red Sea-Suez Rift. Late Cenozoic tectonics show the occurrence of two successive compressions, NW-SE then both NE-SW and ~N-S, which generally reflect a continental collisional setting between the Arabian and Eurasian plates.

    A Three-dimensional, finite-difference, groundwater flow model of the Prairie du Chien-Jordan aquifer was developed to assess the movement of coal-tar derivatives from a coal-tar distillation and wood-preserving plant in St. Louis Park, Minnesota. The model was calibrated for steady-state and transient conditions. Sensitivity testing indicated that leakage to the upper model layer and the vertical hydraulic conductivity of the basal confining unit of the St. Peter were the most sensitive model hydrologic properties. Model simulations indicated that water introduced into the aquifer through wells open to several aquifers would raise the potentiometric surface of the Prairie du Chien-Jordan by as much as 3 ft in the area of the former plant. Other simulations suggested that withdrawal from certain upgradient wells may have altered local hydraulic gradients. These factors contributed to the potential for movement of contaminants from the area of the former plant to wells. Simulations of a proposed gradient-control plan indicate that the actions would be effective in limiting the expansion of the contaminated volume. These simulations also show, however, that control of discharge from all wells in the area will be important to the overall effectiveness of the plan. (USGS)

    Objectives. To assess the impact of live interactive telecardiology on diagnosis and disease management, patients' quality of life, and time- and cost-savings. Methods. All consecutive patients who attended or were referred to the teleclinics for suspected cardiac problems in two hospitals in remote areas of Jordan during the study period were included in the study. Patients were interviewed for relevant information and their quality of life was assessed during the first visit and 8 weeks after the last visit. Results. A total of 76 patients were included in this study. Final diagnosis and treatment plan were established as part of the telecardiology consultations in 71.1% and 77.3% of patients, respectively. Patients' travel was avoided for 38 (50.0%) who were managed locally. The majority of patients perceived that the visit to the telecardiology clinic results in less travel time (96.1%), less waiting time (98.1%), and lower cost (100.0%). Telecardiology consultations resulted in an improvement in the quality of life after two months of the first visit. Conclusions. Telecardiology care in remote areas of Jordan would improve the access to health care, help to reach proper diagnosis and establish the treatment plan, and improve the quality of life. PMID:25400661

Telecardiology care in remote areas of Jordan would improve the access to health care, help to reach proper diagnosis and establish the treatment plan, and improve the quality of life. PMID:25400661

  12. A case study of ancient mortars and concretes from Umm al-Jimal, Jordan with implications for archaeological site conservation

    Dunn, Edith Ann

    The excavation at Umm al-Jimal, a Late Roman-Byzantine site in northeast Jordan, yielded large amounts of fragmented mortar and concrete. These materials are relevant both to the archaeological context and to the continued care and management of the site. An analysis of the mortars and concretes can reveal the geologic origin of the raw materials, how they were processed, and how technology changed over time. This information, when viewed within the context of the inhabitational history of the site, contributes to an understanding of the site's historic development. It may also shed light on various social, economic and technological aspects of the people who manufactured these materials. The management of archaeological sites is usually designed as an afterthought to archaeological research. Unfortunately one result is that valuable information can be lost or remain uncollected. There is often a great deal of useful information present in the archaeological record which could be helpful to archaeological site conservators, engineers and planners. Specifically, a complete understanding of the site's original architectural materials provides a basis for decisions regarding the preservation and management of existing site features. Stabilization of existing standing structures cannot be accomplished without an understanding of the original materials used in their construction. In order to maximize the information available to archaeological site managers, a comprehensive site management plan must be an integral component of the archaeological research design and implementation. This requires integrating an investigation of construction materials into the original archaeological research model. The origin, manufacture, use and subsequent deterioration of these materials, as well as their archaeological context are important to the conservation plan. Ancient mortars and concretes from Umm al-Jimal proved to be complex mixtures containing both raw geologic, biological and human processed components. This formulation gave the original mortars and concretes specific qualities of physical strength and durability. These compounds are markedly different from modern materials, such as Portland cement, frequently used to "stabilize" archaeological structures. Analysis indicates that all of the materials used in the manufacture of the ancient mortars and concretes were locally available to the historic occupants of Umm al-Jimal.

    Water is a valuable resource, especially in arid and semi arid areas. In order to do proper management of the water resources, studies on the aquifer system is essential. The study case is located in the lower part of the western Jordan Valley. This karstic area has different systems from which the upper and lower Mountain aquifer systems. Two representative springs were chosen for each aquifer, Sultan spring for the lower aquifer and Auja spring for the upper one. Sultan spring has a continues and constant discharge rate through the year while Auja spring has high oscillation in discharge accompanied by frequent dry-out in summer months and fast response to precipitation events. The two systems have been thought to be separated by an aquiclute, however after frequent intensive sampling of both springs during the raining winter season, This study shows that with the exception of Na+ and Cl- all other concentration of ions are very similar. The average of Sodium for Sultan spring is 33 mg/L, while the average Chloride for the same spring is 54.5 mg/L. As for Auja spring the average Sodium and Chloride are 24 mg/L and 39.4 mg/L respectively, therefore, the water of Sultan spring contains higher content of sodium and chloride than Auja, this could be related to the chemistry of the lower aquifer. The ratio of Na+/Cl- for Sultan and Auja springs are 0.92 and 0.94 respectively, this indicates that Auja is close to the rain ratio of 0.86 while Sultan (although slightly higher) may be closer to the Halite ratio of 1. The isotopic signature of 18O for both springs has shown to be very similar with only a -0.5‰ of difference in most cases, with a range of -5.2‰ to -6.2‰ for Sultan and -5.4‰ to -6.2‰ for Auja spring. These results may indicate the same recharge elevation for both springs in the Mountain area. On the other hand, in some places east to the major fault system, the shallow aquifer's 18O content in Jericho is close to that of Sultan spring, which could indicate that the hydraulic connection between the Mountain and shallow aquifer is present across some windows.

    The Dead Sea is a pull-apart basin forming a terminal lake (-429 m) located over the Jordan - Dead Sea transform fault. The slope of the fresh/saline interface is ten times shallower than observed near the ocean because salinity is ten times greater than in the average sea water. Underground lateral extension is acting as a high density layer over which groundwater is in hydrostatic equilibrium. Since the 1960s, a slice of brine 0.033 km x 77 km x 16.5 km vanished due to water resources over-exploitation in the catchment area. Monitoring of wells in the Dead Sea zone indicated that the water table does not drop at the same pace as the lake. The head difference is increasing with time. Groundwater moves so rapidly towards the lake to compensate for the imbalance provoking the proliferation of sinkholes, subsidence, and landslides. Since the 1980s, the emerged spaces have been covered by industrial and touristic infrastructures. Such a dynamic system provides a test bed to study an Early Warning System to help minimizing geo-hazards effects. The reactivation of a paleo-channel located below a US 48 M salt evaporation pond of the Arab Potash Company, Lisan peninsula, provides an illustrative case-study. Sinkholes lineaments whose orientations fit with the main structural directions highlight the role of conduit played by faults and fractures. Rapid underground water circulation explains the appearance of tamarisk in unexpected places. Time series analysis of high and very high resolution visible/radar satellite images acquired from the 1970s and on indicated major changes in the landscape. This work underlines the need of very carefully analyzing all available data sources acquired prior to and during the recession of the lake level before the development of human activities along the coast.

Jaman Sarayreh, Chairman of the Arab Potash Company, and to Dr Dureid Mahasneh et Mr. Bisher Mahasneh for their important support.

    The recurrence of large and destructive earthquakes along major fault systems is key to understanding the seismic cycle, the driving mechanism and forecast future behavior. We study the ~ 110-km-long Jordan Valley Fault segment (JVF) of the North-South trending Dead Sea Transform Fault and plate boundary by means of two independent approaches: i) the build-up of a paleoseismic catalogue of surface-rupturing events for the last 14 kyr, and ii) the construction of a history of slip rate over the last 48.5 kyr from different generations of left-lateral offset streams of the late Pleistocene and Holocene Lissan lacustrine deposits. Firstly, we combine published historical data, re-appraised archaeological data and paleoseismic trenching to produce and unprecedentedly complete catalogue of large (Mw > 7) earthquakes with at least 13 events in the last 14 kyr. The average ~1000 yrs recurrence interval presents large variations from 300 to more than 1500 yrs, with the various datasets intersecting and completing each other. Secondly, we present a detailed map of the active fault trace that intersects a set of 20 gullies. Stream incisions are classified as a function of their depth and relative age and characterized in terms of cumulative offsets. Absolute ages are obtained from paleoclimatic analysis of lacustrine deposits. Using the numerous isotopic dating of lacustrine deposits, lake-level fluctuations and extreme rainfall episodes, we obtain an average 4.9 mm/yr slip rate with extreme values of 3.5 and 11 mm/yr. Our results indicate slip rate variations and provide evidence for episodic faulting behavior. Both approaches indicate that the JVF encounters periods of increased seismic activity which suggests episodicity or mode-switching. Reduced recurrence intervals and/or larger co-seismic slip (and magnitudes) are required to account for observations as suggested by GPS observations (4.5 mm/yr) and seismic moment summation. The JVF has accumulated 3.5 m to 5 m of slip deficit after the AD 1033 earthquake and may be the site for a large earthquake in the near future.

    In October 2013 a shear wave reflection seismic pilot study was carried out at the most destructive sinkhole site in Jordan, close to the village of Ghor Al Haditha at the South-East end of the Dead Sea. The investigation is part of the DEad SEa Research Venue (DESERVE), a virtual institute of the Helmholtz Association, designed as a cross-disciplinary and cooperative international project of the Helmholtz Centers KIT, GFZ, and UFZ, and their partners. Since nearly 30 years - apparently contemporaneous to the rapid decrease of the Dead Sea level - ongoing unknown sinkhole processes in the subsurface continuously compromise farming areas, housings, industrial sites, and infrastructure at the investigation site, resulting in massive destructions. Similar processes are observed also at the western border of the Dead Sea. Although many geophysical studies have been carried out at the site since more than 20 years, the subsurface structure and the process itself is quite unknown until yet. In recent years, a massive salt layer at 40 m depth or more was proposed below alluvial fan deposits, which was the target of this reflection seismic pilot study. We spent 10 days in the field and acquired four shear-wave reflection seismic profiles of 1.8 km total length to yield a high-resolution structural image of the subsurface. The lines cover in NW-SE and NE-SW direction the sinkhole-affected area as close as possible to recent collapse structures. There is no evidence for the hypothesized shallow salt layer, at least not down to 100 m probably up to 200 m depth. Instead, the detected subsurface structures show a complex interlock of alluvial fan deposits and marine sedimentation layers of the Dead Sea between 0-200 m depth. Therefore, we propose a new hypothesis for the sinkhole processes in the region: salt-rich marine clay layers are present in the fresh water contact zones inside the alluvial fan, which are destabilized and mobilized by dissolution of the salt contained. This suggestion is well supported by surface observations at the current border of the Dead Sea. Similar leaching effects are well known from the quick-clay problem in e.g. Scandinavia. Time-lapse profiling at the investigation site in the upcoming years should lead to a better knowledge of the subsurface processes.

    Objectives To examine the prevalence of unsafe sexual behaviour, sexually transmitted infection (STI)-related knowledge, health and work-related conditions, and correlates of practising unsafe sex among domestic and foreign male workers in multinational workplaces in Jordan. Design Cross-sectional behavioural assessment survey. Setting Multinational workplaces in Jordan. Participants 230 Jordanian and 480 foreign male workers aged ≥18 years who had worked in a Qualified Industrial Zone (QIZ) for 12 months or more. Outcomes The primary outcome was the prevalence of practising unsafe sex. ‘Unsafe sex’ was defined as sex with a non-regular sexual partner with inconsistent condom usage. Results Overall, 74.3% of workers reported lifetime sexual experience. The proportion of lifetime unsafe sex was similar among domestic (31.8%) and foreign (35.6%) workers. Of those, 59.2% of domestic and 68.1% of foreign workers started practising unsafe sex after joining the QIZ. Rates of lifetime unsafe sex were significantly higher among those who had their sexual debut after joining the QIZ in domestic (aOR, 2.2, 95% CI 1.1 to 4.4) and foreign workers (aOR, 2.4, 95% CI 1.4 to 4.1). Among the domestic workers, being 18–24 years old (aOR, 4.9), unmarried (aOR, 4.8), working in the QIZ for 5–8 years (aOR, 5.0), sometimes/frequently shopped with foreign workers (aOR, 2.1) or were current/ex-alcohol drinkers (aORs, 3.4) were independently significantly associated with higher odds of practising unsafe sex. Conclusions A significant proportion of domestic and foreign male workers had been practising unsafe sex. The findings indicated that not only foreigners but also domestic male workers associating with foreign workers are at high risk of unsafe sex. Tailored interventions to promote safer sex in multinational workplaces in Jordan are needed. PMID:26068511

    The prevalence of diabetes in Jordan has been increasing. The early diagnosis of diabetes is vital to slow its progression. The Arab Risk (ARABRISK) screening tool is a self-administered questionnaire used to determine people who are at high risk for developing diabetes. This study aimed to identify people at high risk for developing type 2 diabetes by using the ARABRISK in the capital of Jordan.A cross-sectional study was conducted with a convenience sample of people in the capital of Jordan. The ARABRISK screening tool was administered to identify the participants' risk for developing diabetes. In addition to descriptive statistics, percentages of the ARABRISK categories were represented, and an independent samples t test was used to explore the differences between men and women. A total of 513 participants with a mean age of 51.94 (SD = 10.33) were recruited; 64.9% of the participants were men (n = 333).The total ARABRISK score ranged from 0 to 25 with a mean score of 12.30 (SD = 4.76). Using the independent samples t test, women (mean = 13.25, SE = 0.10) had significantly higher ARABRISK total scores than men did (mean = 12.95, SE = 0.09), t(141) = -2.23, P = 0.03 in the "moderate risk" category. All of the items in the ARABRISK questionnaire were found to be good predictors of the ARABRISK total scores. Among them, age, body mass index (BMI), and high blood glucose (HBG) were the best predictors as indicated by the standardized regression coefficient (β). Older age, obesity, elevated weight circumference, absence of daily physical activity, daily consumption of fruits/vegetables, presence of high blood pressure (HBP), and HBG were significantly associated with increased odds of high ARABRISK total scores. Neither a history of gestational diabetes nor a positive family history was associated with an increased odds of high ARABRISK total scores.By identifying risk factors in these participants, interventions and lifestyle changes can be suggested and implemented to reduce the risk and incidence of diabetes.

    This study documents for the first time tidal bundling in a lower Paleozoic sheet sandstone from the cratonic interior of North America, providing insights into the hydrodynamics of ancient epicontinental seas. The Jordan Sandstone (Upper Cambrian) in the Upper Mississippi Valley contains large-scale planar tabular cross-sets with tidal-bundle sequences, which were analyzed in detail at an exceptional exposure. Tidal-bundle sequences (neap-spring-neap cycles) were delineated by foreset thickening-thinning patterns and composite shale drapes, the latter of which represent accumulations of mud during the neap tides of neap-spring-neap tidal cycles. Fourier analysis of the bundle thickness data from the 26 measurable bundle sequences revealed cycles ranging from 15 to 34 bundles per sequence, which suggests a semidiurnal or mixed tidal system along this part of the Late Cambrian shoreline. We extend the tidal interpretation to widespread occurrences of the same facies in outcrops of lesser quality, where the facies is recognizable but too few bundles are exposed for tidal cycles to be measured. By doing so, this study shows that tidally generated deposits have a significant geographic and temporal extent in Upper Cambrian strata of central mid-continent North America. The deposition and preservation of tidal facies was related to the intermittent development of shoreline embayments during transgressions. The tidally dominated deposits filled ravined topographies that were repeatedly developed on the updip parts of the shoreface. Resulting coastal geomorphologies, accompanied perhaps by larger-scale changes in basinal conditions and/or configuration, led to changes in depositional conditions from wave-dominated to tide-dominated. Outcrops of the Jordan Sandstone tidal facies in the Upper Mississippi Valley represent the farthest inboard recorded transmission of ocean-generated tides in the Laurentian epicontinental seas, demonstrating that tidal currents were significant agents in the transport of sand along the far cratonic interior shorelines of Cambrian North America. The results of this study improve the facies-level understanding of the genesis of sheet sandstones. Furthermore, tidalites documented here occur in a specific position within a sequence stratigraphic architecture for the Jordan Sandstone. This provides a framework to compare these ancient deposits and processes to younger (e.g., Carboniferous) epicontinental systems where stratal and sediment dynamics are better documented. ?? 2003, SEPM (Society for Sedimentary Geology).

  20. Cadomian (∼560 Ma) crust buried beneath the northern Arabian Peninsula: Mineral, chemical, geochronological, and isotopic constraints from NE Jordan xenoliths

    In order to better understand the nature and formation of the lower continental crust beneath northern Arabia, we studied lower crustal xenoliths brought up by Neogene basalts in NE Jordan. Most of these xenoliths are comprised of primary phases plagioclase + two-pyroxenes with magnetite and ilmenite. Most clinopyroxene are augite whereas orthopyroxene mostly are hypersthene (Mg# = 50-80). Plagioclase feldspar is dominantly andesine-labradorite; pyrope-rich garnet and Fe-rich olivine (Fo75 to Fo62) are rare. These xenoliths represent cumulates formed from intermediate magmas that pooled in the lower crust. Many xenoliths also contain small, fine-grained K-rich zones interpreted as melt pockets reflecting late magmatic infiltration of the lower crust. The xenoliths display a wide range in major element compositions (37-51 wt.% SiO2, 4-15 wt.% MgO and 0.1-6.3 wt.% TiO2), enrichment in Ba, K, Sr, Pb and Eu, and some trace element ratios atypical of bulk continental crust (e.g., K/Rb = 1265 ± 565, K/U = 63 000 ± 60 080 and Th/U = 0.96 ± 0.56); these extreme ratios reflect widespread K-metasomatism associated with melt pockets. The magmas from which these cumulates formed may have been generated at a reararc convergent margin setting. Four U-Pb zircon populations yield indistinguishable ages of 554 ± 4 Ma; 559 ± 5 Ma; 559 ± 6 Ma, and 563 ± 5 Ma. Initial 87Sr/86Sr values (0.70260-0.70352) and positive εNd(560) (with the exception of a single, more radiogenic sample (+9.6), range = + 1.3 to +4.8) indicate that the lower crust sampled by the xenoliths originated in the asthenospheric mantle, with little or no interaction with older crust, although Pb isotopic compositions allow for some interaction with older or subducted crustal materials. We interpret the geochemistry and mineralogy of these xenoliths to indicate that the lower crust beneath NE Jordan is mafic and comprised of plagioclase-rich 2-pyroxene igneous rocks. The lower crust of this area formed by magmatic underplating over less than 18 Ma. The crust of NE Jordan is significantly younger than the crust of the northernmost Arabian-Nubian Shield and represents a fragment of Cadomian (600-520 Ma) crust that may make up the NE margin of the Arabian Plate.
