    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

    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.

    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

    The Jordan River in Midvale and West Jordan, Utah, flows adjacent to two U.S. Environmental Protection Agency Superfund sites: Midvale Slag and Sharon Steel. At both sites, geotechnical caps extend to the east bank of the river. The final remediation tasks for these sites included the replacement of a historic sheet-pile dam and the stabilization of the river banks adjacent to the Superfund sites. To assist with these tasks, two hydraulic modeling codes contained in the U.S. Geological Survey (USGS) Multi-Dimensional Surface-Water Modeling System (MD_SWMS), System for Transport and River Modeling (SToRM) and Flow and Sediment Transport and Morphological Evolution of Channels (FaSTMECH), were used to provide predicted water-surface elevations, velocities, and boundary shear-stress values throughout the study reach of the Jordan River. A SToRM model of a 0.7 mile subreach containing the sheet-pile dam was used to compare water-surface elevations and velocities associated with the sheet-pile dam and a proposed replacement structure. Maps showing water-surface elevation and velocity differences computed from simulations of the historic sheet-pile dam and the proposed replacement structure topographies for streamflows of 500 and 1,000 cubic feet per second (ft3/s) were created. These difference maps indicated that the velocities associated with the proposed replacement structure topographies were less than or equal to those associated with the historic sheet-pile dam. Similarly, water-surface elevations associated with the proposed replacement structure topographies were all either greater than or equal to water-surface elevations associated with the sheet-pile dam. A FaSTMECH model was developed for the 2.5-mile study reach to aid engineers in bank stabilization designs. Predicted water-surface elevations, velocities and shear-stress values were mapped on an aerial photograph of the study reach to place these parameters in a spatial context.

    In the age-old debate between technological optimists and pessimists, desalination has been hailed as a "game changer" that can fundamentally alter the dynamics of water management under conditions of scarcity. While water from desalination facilities can reduce uncertainties in municipal supply, they are unlikely to replace the missing flow required to rehabilitate rivers and streams. The Jordan River is an iconic, but highly degraded water body whose restoration has been the subject of extensive research as well as numerous proposals and strategies. A review of the present state of the River and prospects for successful rehabilitation efforts reveals that neither the increase in the riparian population nor the reduced water supply due to climate change in the Jordan basin has been considered sufficiently in restoration strategies. Demographic pressures produce acute water shortages which make the provision of future environmental flows highly unlikely. While much can and should be done to improve its environmental condition, the Jordan River offers a cautionary tale for water scarce regions about the challenge of stream restoration initiatives in the face of accelerated population growth, notwithstanding the potential benefits of desalination as a source of drinking water.

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

    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

    2015-04-01

    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

    The Jordan River is a 51 mile long freshwater stream in Utah that provides drinking water to more than 50% of Utah's population. The various point and nonpoint sources introduce an excess of nutrients into the river. This excess induces eutrophication that results in an inhabitable environment for aquatic life and is expected to be exacerbated due to climate change. Adaptive measures must be evaluated based on predictions of climate variation impacts on eutrophication and ecosystem processes in the Jordan River. A Water Quality Analysis Simulation Program (WASP) model was created to analyze the data results acquired from a Total Maximum Daily Load (TMDL) study conducted on the Jordan River. Eutrophication is modeled based on levels of phosphates and nitrates from point and nonpoint sources, temperature, and solar radiation. It will simulate the growth of phytoplankton and periphyton in the river. This model will be applied to assess how water quality in the Jordan River is affected by variations in timing and intensity of spring snowmelt and runoff during drought in the valley and the resulting effects on eutrophication in the river.

    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.

  15. The spatial distribution of enteric bacteria in the Jordan River-Lake Kinneret contact zone.

    Lake Kinneret, in the north of Israel, is the only freshwater body in the country. It supports many activities, including recreation, tourism, and a commercial fishing industry, but its prime function is to supply water to other parts of the country. Consequently, maintaining a high water quality of the lake is of prime importance. The major part (some 90%) of the annual runoff of water enters Lake Kinneret from the north via the Jordan River during the autumn-winter floods. During this period, the river carries sediments, toxic agricultural chemicals, and allochthonous organisms, including pathogenic bacteria, into the lake. The Jordan River-Lake Kinneret contact zone is characterized by a rapid transformation from a riverine to a lacustrine water mass within 700 m from the river mouth, with very high spatial gradients of practically all hydrodynamic, hydrophysical, hydrochemical, and microbiological parameters. Previous measurements have shown that the distribution of enteric bacteria in the river-lake contact zone is related to the attenuation of river current flows. The aim of this study was to determine whether the change in the number of enteric bacteria (fecal coliforms, Escherichia coli, and Klebsiella spp.) in the water of the River Jordan-Lake Kinneret contact zone was due to sedimentation or to dilution. The data were then utilized to build a conceptual model explaining the distribution of biological pollutants (bacteria) in the river-lake contact zone of a shallow tropical lake, using the microbial communities of the River Jordan-Lake Kinneret contact zone, as an example.

    The study describes the hydrology and chemistry of the shallow groundwater along the west side of the Lower Jordan River in its north section, by means of piezometers installation. We have installed 7 piezometers at different locations near the west bank of the Jordan River and added five reference points inside the river itself. The immediate purpose of these installations is to measure the groundwater level, to calculate the water gradient, to estimate the amount of water that enters the river, to sample the shallow groundwater, and provide a chemical analysis of these samples. The study area was divided into three fields, north, middle, and south where in each field a number of piezometers where drilled and one or two reference points were placed in the river. The highest gradient of the hydraulic head was measured in the north field and reached 5 m over a distance of ~500 m. This may be explained by the alluvial fan of the largest stream in the area. In the middle field the gradient of the hydraulic head was between 0.6 and 0.8 m over a distance of 170 - 380 m and in the south field we measured the smallest hydraulic gradient that was less then 0.1%. The chemical characteristics of the river show a chloride decrease from ~1900 mg/L to ~1500 mg/L and then a slight increase to ~ 1600 mg/L. Since the river is not only affected by the groundwater but also by surface inputs from the west and the east, and by intensive pumping, the interpretation and the comparison between the river data and the piezometers is complex. Never the less, there is a significant difference between the three fields. Where the chloride concentration in the north field is lower than that of the river the chloride concentration in the other two fields is higher than in the river. As the gradient of the hydraulic head found in the north field is high it is likely that some part of the river modification may be attributed to the sampled water in the piezometers. On the other hand, the very high

    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

    Water-quality studies were conducted on the Jordan River, Utah, to investigate specific problems: dissolved oxygen, toxic substances, sanitary quality, and turbidity and suspended sediment. The dissolved oxygen decreased from 8 milligrams per liter at the Jordan Narrows to less than 5 milligrams per liter at 500 North Street. Chemical oxygen demand increased about 23 percent and biochemical oxygen demand increased 90 percent. Nearly 78 percent of the water samples analyzed for total mercury exceeded the State intended-use standard of 0.05 microgram per liter. Concentrations of ammonia, cadmium, copper, lead, and zinc exceeded the standards periodically. The pesticides DDD, DDE, DDT, dieldrin, methoxychlor, and 2,4-D were occasionally detected in bottom materials. Most were present in quantities of less than 15 micrograms per kilogram. Concentrations of three indicator bacteria (total coliform, fecal coliform, and fecal streptococcus) increased in a downstream direction. Concentrations of total coliform bacteria often exceeded 5,000 colonies per 100 milliliters and concentrations of fecal coliform bacteria often exceeded 2,000 colonies per 100 milliliters. The primary sources of turbidity in the Jordan River are Utah Lake and discharges from the wastewater-treatment plants. Large values of turbidity were measured at the Jordan Narrows with a summer mean value of 88 nephelometer turbidity units (NTU) and a winter mean value of 43 NTU. (USGS)

    A reconnaissance of toxic substances in the Jordan River, Salt Lake County, Utah, was made during July 1980 to October 1982 as part of a larger study of the river that included studies of sanitary quality, dissolved oxygen, and turbidity. Samples for toxic substances were collected at five sites on the Jordan River, at three major tributaries, and at six storm conduits. The toxic substance that most frequently exceeded State standards was total mercury. About 78% of the 138 samples for total mercury exceeded the State standard of 0.05 microgram per liter. Other toxic substances that exceeded State standards were: ammonia, cadmium, copper, zinc, and lead. One sample for cyanide and one for iron also exceeded State standards. The diversity of toxic substances with concentrations large enough to cause them to be problems increased from the upstream sampling site at the Jordan Narrows to the next two downstream sites at 9000 South and 5800 South Streets. Concentrations of trace elements in stream-bottom materials also increased in a downstream direction. Substantial increases first were observed at 5800 South Street, and they were sustained throughout the downstream study area. Iron is transported in the greatest quantity of all the trace elements studied, with a mean load of 110 pounds per day. Notable loads of barium, boron, lead, and zinc also are transported by the river. DDD, DDE, DDT, dieldrin, heptachlor, methoxychlor, PCB, and 2,4-D were detected in bottom materials; and DDE, Silvex, and 2,4-D were detected in water samples. Chloroform was detected in the storm conduits that empty into the Jordan River. Several metals and phenol also were detected in the samples analyzed for priority pollutants. 15 refs., 1 fig., 14 tabs.

    1906-01-01

    The valleys of Utah Lake and Jordan River are situated in north-central Utah, in the extreme eastern part of the Great Basin. The lofty Wasatch Range (Pl. I), the westernmost of the Rocky Mountain system, limits the valleys on the east, and relatively low basin ranges - the Oquirrh, Lake, and East Tintic mountains - determine them on the west. The valleys trend north and south, and are almost separated by the low east-west Traverse Range, the slopes of which constitute a dam for Utah Lake, which drains through Jordan River to Great Salt Lake.The area under consideration is the most populous and flourishing part of the State, Salt Lake City and Provo, the first and third cities in the State, and many other thriving settlements are there located. At Bingham Junction and Murray a number of smelters treat the ores from near-by mines, but agriculture is the main industry. Water for irrigation is supplied by mountain streams, and intensive farming is successfully pursued. The practice of irrigation was begun by the Mormon pioneers in 1847, and has been discussed in several publications; little attention, however, has been given to the underground water resources, and, so far as the writer is aware, they have not before been described. The present paper outlines conditions of occurrence of the subterranean waters and describes their development in the valleys of Utah Lake and Jordan River.

    The Lower Jordan River (LJR) is a major ecosystem in the semi-arid to arid Jordan-Dead Sea Graben, the backbone of abundant farming activities in the Lower Jordan Valley and the major inflow to the dying Dead Sea. During the 1960's the Sea of Galilee and the Yarmouk River, the main sources of the river, were dammed, decreasing its annual flow from ˜1.2×109 m3 to less than 0.2×109 m3, leaving a mix of point and non-point sources composing its base flow. Beside natural saline springs along its course, current day anthropogenic sources (e.g. sewage, agricultural return flow and fishpond effluents) have a negative impact on the water quality and the ecosystem, contributing high salinity and causing overall pollution. To enable an environmental assessment of the river and to satisfy the regulations of LJR international treaties, the temporal dynamics of water quantity and quality must be observed on a regular basis. As the LJR forms the highly secured border between Jordan, Israel and the Palestinian Authority, nearly the entire river course is physically inaccessible. To overcome that situation, considerable efforts have been made to install a network of 7 sampling stations along the LJR to identify and separate the different contributing sources. Automatic water samplers in three of the stations collect water daily in addition to continuous measurement of stage, EC, pH and temperature. Sensors at all locations transmit online real-time data. During monthly campaigns a total of 14 sites are manually sampled along the river and some tributaries. Water samples are analyzed for major ions, trace elements and stable isotopes. While the sensor network allows separating events occurring in different reaches along the river course and calculating travel time between stations, water sample analyses enable fingerprinting and separating the actual sources. By doing so, an unusual and very local event was recorded by the most southern station (5.5 km north of the Dead Sea

    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.

    Whether water resource developers are utility operators, cities, industrialists of agriculturalists, their interests and those of affected landowners must accommodate each other. They must come together as men, and compromise their difficulties. Past disputes and their resolutions are guides to present and future flood-hazard settlement. Utah Lake and the Jordan River were once the setting for an equitable settlement of a flood hazard. In 1885, President John Taylor (President Taylor) of the Church of Jesus Christ of Latter-day Saints played a significant role in bringing about a compromise between downstream water users in Salt Lake County, Utah, and adversely affected upstream landowners in Provo and other parts of Utah County. Subsequent periodic flooding resulted in a second compromise agreement a century later. This paper considers the Utah Lake and Jordan River experiences. It examines the two compromises, how they came about, and their impact upon water resource management. In addition to their historical interest, these settlements provide useful guidance for negotiation and resolution of flood hazard disputes.

  7. Sanitary quality of the Jordan River in Salt Lake County, Utah

    1984-01-01

    This investigation of the sanitary quality of the Jordan River was conducted from July 1980 to October 1982 using indicator bacteria rather than specific pathogens. A serious sanitary problem was identified. Concentrations of total coliform bacteria often exceeded 5,000 colonies per 100 milliliters and concentrations of fecal coliform bacteria often exceeded 2,000 colonies per 100 milliliters in the lower reaches of the river. At times these levels were greatly exceeded. The most conspicuous aspect of the bacteriological data is its extreme variability. Seven waste-water treatment plants, seven major tributaries, numerous storm conduits, irrigation-return flow, and other sources all contribute to the dynamic system that determines the sanitary quality of the river. Because of this variability the sanitary quality of the river cannot be predicted at any one time. In general, concentrations of all three indicator bacteria increased in a downstream direction. Storm runoff from urban areas contributed large concentrations of indicator bacteria to the river. Regression analysis of 9 years of data collected at 1700 South Street showed a significant positive correlation between both fecal coliform and fecal streptococcal concentrations versus time. Concentrations of fecal coliform and fecal streptococci have both been increasing since 1974 at 1700 South Street. (USGS)

    During the past several decades the volume of freshwater carried by the Lower Jordan River (LJR) has been reduced by 90% due to damming of its main tributaries, leaving a mixed flow of polluted and brackish to saline water from anthropogenic and partly known geogenic sources. Since the river represents the highly secured border between Jordan, Israel and the West Bank, neither systematic nor long-term measurements were conducted in it. Only vague knowledge exists about the amount and composition of natural contributors and no knowledge concerning their temporal dynamics. However, since the river water is intensely used for irrigation along its course and represents the major source of water to the Dead Sea, the spatio-temporal variation of water discharge and chemistry are required for water resource assessment in the Lower Jordan Valley and the Dead Sea. To monitor the temporal variations of water discharge and hydrochemistry, an automatic sampler, including water level and EC sensors with real time transmission were installed at the Baptism site, a few kilometers upstream of the delta. Major ions are analyzed on a daily basis, while stable isotopes of sulfate (δ34S, δ18O), nitrate (δ15N, δ18O) and water (δ2H, δ18O) are analyzed on an event basis. A general inverse correlation between EC and water level was found although extreme high conductivity values relate to flood events during the wet period. Due to the high-resolution monitoring, a series of flood events could be observed, some having unusually high saline water. Results from Cl/Br, Na/Cl, Mg/Ca, δ34S allow separation and identification of sources: (i) the dissolution of evaporite minerals, abundant in the surrounding geological strata, (ii) sewage and (iii) brine springs. The continuous monitoring is an essential tool for understanding long-term processes and changes in such a dynamic system, and is crucial for identifying rarely occurring extreme flow events. However, a single sampling location is

    The Eastern Mediterranean and Near East (EM/NE) is an extremely water scarce environment. It is expected that problems will increase due to climate change and population growth. The impact of climate change on water availability in EM/NE and in particular the Jordan River catchment is investigated in this study. Focus is set on the Upper Jordan River catchment (UJC) as it provides 1/3rd of freshwater resources in Israel and Palestine. It is a hydro-geologically extremely complex region with karstic groundwater flow and an orography with steep gradients. The methods used are high resolution coupled regional climate - hydrology simulations. Two IPCC scenarios (A2 and B2) of the global climate model ECHAM4 have been dynamically downscaled using the non-hydrostatic meteorological model MM5 in two nesting steps with resolutions of 54x54 km2 and 18x18 km2 for the period 1961-2099, whereby the time slice 1961-1989 represents the current climate. The meteorological fields are used to drive the physically based hydrological model WaSiM applied to the UJC. The hydrological model computes in detail the surface and subsurface water flow and water balance in a horizontal resolution of 450 x 450 m2 and dynamically couples to a 2-dim numerical groundwater model. Parameters like surface runoff, groundwater recharge, soil moisture and evapotranspiration can be extracted. Results show in both scenarios increasing yearly mean temperatures up to 4-5 K until 2099 and decreasing yearly precipitation amounts up to 25% (scenario A2). The effect on the water balance of the UJC are reduced discharge and groundwater recharge, increased evaporation and reduction of snow cover in the mountains which usually serves as an important freshwater reservoir for the summer discharge.

    Jordan is an arid country, facing great challenges due to limited water resources. The shortage of water resources constrains economy, especially agriculture that consumes the largest amount of available water (about 53 % of the total demand). According to the Jordan Water Strategy 2008 - 2022, groundwater is twice greater than the recharge rate. Therefore, the government charged the planners to consider treated wastewater (TWW) as a choice in the water resources management and development strategies. In Jordan, there are 31 TWW plants. Among them, As Samra plant serving the two major cities, Amman and Zarqa, is the largest, with projected maximum capacity of 135 Million m3/year. This plant is located upstream of the Zarqa River basin that accepts all TWW discharges. The Zarqa River is considered the most important source of surface water in Jordan and more than 78 % of its current is composed of TWW. The main objectives were to develop a conceptual model for a selected part of the Zarqa River basin, including the As Samrapant, and to provide insights to water resources management in the area using TWW. The groundwater flow model was developed using MODFLOW 2005 and used to assess changes in the aquifer and the Zarqa River under a set of different increments in discharge rates from the As Samra plant and different groundwater pumping rates. The results show that the water table in the study area underwent an average water table decline of 29 m prior to the As Samra plant construction, comparing with the current situation (with annual TWW discharge of 110 Million m3). The analysis of the TWW rate increase to 135 million m3/year (maximum capacity of the As Samra plant) shows that the average groundwater level will rise 0.55 m, compared to the current conditions. We found that the best practices require conjunctive use management of surface- and groundwater. The simulated scenarios highlight the significant role of TWW in augmenting the aquifer storage, improving

    The Jordanian part of the Jordan river basin is almost 3679.692 km2. The river flows within the Jordan Rift Valley, a structurally complicated region which is cover almost by Upper Cretaceous chalky marls, bituminous limestone and nodular limestone, while the Quaternary sediments are mainly fluvitile deposits and Lisan marls. Other deposits are Tertiary and Jurassic. The present study includes the selected drainage basin characteristics, part of these characteristics refer as primary characteristics measurements and the others are found and concluded from the primary drainage basin characteristics and name as calculated basin characteristics. The drainage pattern is mainly dendritic but in some part is shows parallel pattern but not very mature. To simplify the study more and based on the detailed analysis of the drainage selected characteristics of the study area using various techniques and both topographic and geologic maps, the Jordan river basin is furtherly divided into 10 sub basin.

    Sediments from the basin of Jordan River are to some extent significantly contaminated by heavy metals. The goal of this study was to examine the nature of the heavy metals, their mobility, and their binding in the soil matrix in order to understand the accumulation mechanism. Exhaustive mineralogical and geochemical study on the heavy metals in the vicinity of the river will allow knowing the dominant forms of emitted metals. The structural local order around Cr and Zn in soil samples were investigated by analyzing XAFS data. Our investigations show that the coordination sphere, around both Cr and Zn, is constituted of oxygen atoms at an interatomic distance of ∼2 Å which is close to those in clay minerals. It is also shown that Cr(III) is the most dominating redox state in soil samples. Moreover, the next backscattering neighbors around Zn and Cr are either carbon or sulfur atoms which reveal a multiple and heterogeneous speciation of Cr and Zn with organic matter.

    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.

    computations of discharge records that would indicate false flow losses. A total of 34 measured discharges at a streamgage on the Haw River below B. Everett Jordan Lake near Moncure were compared with the reported hourly flow releases from Jordan Lake Dam. Because 28 of 34 measurements were within plus or minus 10 percent of the hourly flow releases reported by the U.S Army Corps of Engineers, use of the current discharge computation tables for reporting Jordan Lake Dam flow releases is generally supported. A stage gage was operated on the Cape Fear River at Buckhorn Dam near Corinth to collect continuous stage-only records. Throughout the study period, flow over the dam was observed along its length, and flow loss within the study reach is not attributed to river-level fluctuations at the dam. Water-use information and (or) data were obtained for five industrial facilities, a regional power utility, two municipalities, one small hydropower facility on the Deep River, and one quarry operation also adjacent to the Deep River. The largest water users are the regional power producer, a small hydropower operation, and the two municipalities. The total water-use diversions for these facilities range from almost 25.5 to 38.5 cubic feet per second (39.5 to 59.5 million gallons per day) during the winter and summer periods, respectively. This range is equivalent to 69 to 104 percent of the 37 cubic feet per second median flow loss. The Lockville hydropower station is on the Deep River about 1 mile downstream from the streamgage near Moncure. Run-of-river operations at the facility do not appear to affect flow losses in the study reach. The largest water user in the study area is a regional power producer at a coal-fired power-generation plant located immediately adjacent to the Cape Fear River just downstream from the confluence of the Haw an Deep Rivers. Comparisons of daily water withdrawals, sup-plied by the regional power producer, and discharge records at a streamgage on the

    This paper investigates the extent to which entrenched interests of stakeholder groups both maintain water use practice, and may be confronted. The focus is on the agricultural sectors of Yemen and Jordan, where water resource policymakers face resistance in their attempts to reduce water use to environmentally sustainable levels through implementation of water demand management (WDM) activities. Some farmers in both countries that have invested in irrigated production of high-value crops (such as qat and bananas) benefit from a political economy that encourages increased rather than reduced water consumption. The resultant over-exploitation of water resources affects groups in unequal measures. Stakeholder analysis demonstrates that the more ‘powerful’ groups (chiefly the large landowners and the political elites, as well as the ministries of irrigation over which they exert influence) are generally opposed to reform in water use, while the proponents of WDM (e.g. water resource managers, environmental ministries and NGOs, and the international donor community) are found to have minimal influence over water use policy and decisionmaking. Efforts and ideas attempted by this latter group to challenge the status quo are classified here as either (a) influencing or (b) challenging the power asymmetry, and the merits and limits of both approaches are discussed. The interpretation of evidence suggests current practice is likely to endure, but may be more effectively challenged if a long-term approach is taken with an awareness of opportunities generated by windows of opportunity and the participation of ‘overlap groups’.

    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

    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.

    In the last decade researchers started using ecosystem services as a new framework to understand the relationships between environment and society. Habitat quality and water quality are related with ecosystem services regulation and maintenance, or even provision. According to the Common International Classification of Ecosystem Services (CICES) both habitat quality and water quality are associated with lifecycle maintenance, habitat and gene pool protection, and water conditions, among others. As there is increased pressure on habitats and rivers especially for agricultural development, mapping and evaluating habitat and water quality has important implications for resource management and conservation, as well as for rural development. Here, we model and map habitat and water quality in the Jordan Valley, Jordan. In this study, we aim to identify and analyse ecosystem services both through 1) habitat quality and 2) water quality modelling using InVest, an integrated valuation of ecosystem services and tradeoffs. The data used in this study mainly includes the LULC, Jordan River watershed and main threats and pollutants in the study area, such as agriculture, industry, fish farms and urbanization. Results suggest a higher pressure on natural habitats in the Northern region of the Jordan Valley, where industry is dominant. Agriculture is present along the Jordan Valley and limits the few natural forested areas. Further, water pollution is mainly concentrated in disposal sites due to the low flow of the Jordan River. Our results can help to identify areas where natural resources and water resource management is most needed in the Jordan Valley. Acknowledgements: Transbasin FP7 project

    Combined piped and tanker based water supply systems have become a ubiquitous feature of urban waterscapes in the global South. Jordanian water sector, and Amman in particular has been a recipient of considerable international financial and technical assistance over the past decades. The international assistance has coupled with the Jordanian state's own pro-market ideological stance, and its political compulsions to spawn a techno-social assemblage of water supply that represents a hybrid state and commercial water supply system. I present the results of a field study in Amman, Jordan on water tankers and water users to understand the techno-political underpinnings of the hybrid system and its impact on differential access to water. I explore how Actor Network Theory (ANT) based analysis of tankers, suction pumps and piped water system and their materiality may explain differential access to water. But that exploration is inflected by a larger political ecological concern with questions of power and discourses about citizenship and claim making on the state. I find that ANT based focus on water technologies, while ontologically fertile, and epistemologically innovative, is nevertheless politically barren. Much richer political insights are to be gained from structural and post-structurally based investigations of the discursive and material drivers of the techno-social assemblages of water supply. The technologies don't just neutrally impact water access, but seem to almost intentionally favour the powerful over the powerless. Surely the political agency must not reside in inanimate technologies but in the social actors and structures that fashion those technologies, and configure them such to reinforce geographies of power. I call for a renewed focus on social power and how its impact on lived geographies is mediated by technology.

  8. New River Geothermal Exploration (Ram Power Inc.)

    DOE Data Explorer

    Miller, Clay

    2013-11-15

    The New River Geothermal Exploration (DOE Award No. EE0002843) is located approximately 25km south of the Salton Sea, near town of Brawley in Imperial County and approximately 150km east of San Diego, California. A total of 182 MT Logger sites were completed covering the two separate Mesquite and New River grids. The data was collected over a frequency range of 320Hz to 0.001Hz with variable site spacing. A number of different inversion algorithms in 1D, 2D and 3D were used to produce resistivity-depth profiles and maps of subsurface resistivity variations over the survey area. For 2D inversions, a total of eighteen lines were constructed in east-west and north-south orientations crossing the entire survey area. For MT 3D inversion, the New River property was divided in two sub-grids, Mesquite and New River areas. The report comprises of two parts. For the first part, inversions and geophysical interpretation results are presented with some recommendations of the potential targets for future follow up on the property. The second part of the report describes logistics of the survey, survey parameters, methodology and the survey results (data) in digital documents. The report reviews a Spartan MT survey carried out by Quantec Geoscience Limited over the New River Project in California, USA on behalf of Ram Power Inc. Data was acquired over a period of 29 days from 2010/06/26 to 2010/07/24.

    As renewable generation has become less expensive during recent decades, and it becomes more accepted by the global population, the focus on renewable generation has expanded to include new types with promising future applications, such as river and tidal generation. Although the utilization of power electronics and electric machines in industry is phenomenal, the emphasis on system design is different for various sectors of industry. In precision control, robotics, and weaponry, the design emphasis is on accuracy and reliability with less concern for the cost of the final product. In energy generation, the cost of energy is the prime concern; thus, capital expenditures (CAPEX) and operations and maintenance expenditures (OPEX) are the major design objectives. This paper describes the electrical power conversion aspects of river and tidal generation. Although modern power converter control is available to control the generation side, the design was chosen on the bases of minimizing the CAPEX and OPEX; thus, the architecture is simple and modular for ease of replacement and maintenance. The power conversion is simplified by considering a simple diode bridge and a DC-DC power converter to take advantage of abundant and low-cost photovoltaic inverters that have well-proven grid integration characteristics (i.e., the capability to produce energy with good power quality and control real power and voltage on the grid side).

    Renewable energy sources are the second largest contributor to global electricity production, after fossil fuels. The integration of renewable energy continued to grow in 2014 against a backdrop of increasing global energy consumption and a dramatic decline in oil prices during the second half of the year. As renewable generation has become less expensive during recent decades, and it becomes more accepted by the global population, the focus on renewable generation has expanded from primarily wind and solar to include new types with promising future applications, such as hydropower generation, including river and tidal generation. Today, hydropower is considered one of the most important renewable energy sources. In river and tidal generation, the input resource flow is slower but also steadier than it is in wind or solar generation, yet the level of water turbulent flow may vary from one place to another. This report focuses on hydrokinetic power conversion.

  17. The first polluted river? Repeated copper contamination of fluvial sediments associated with Late Neolithic human activity in southern Jordan.

    The roots of pyrometallurgy are obscure. This paper explores one possible precursor, in the Faynan Orefield in southern Jordan. There, at approximately 7000cal. BP, banks of a near-perennial meandering stream (today represented by complex overbank wetland and anthropogenic deposits) were contaminated repeatedly by copper emitted by human activities. Variations in the distribution of copper in this sequence are not readily explained in other ways, although the precise mechanism of contamination remains unclear. The degree of copper enhancement was up to an order of magnitude greater than that measured in Pleistocene fluvial and paludal sediments, in contemporary or slightly older Holocene stream and pond deposits, and in the adjacent modern wadi braidplain. Lead is less enhanced, more variable, and appears to have been less influenced by contemporaneous human activities at this location. Pyrometallurgy in this region may have appeared as a byproduct of the activity practised on the stream-bank in the Wadi Faynan ~7000years ago. Copyright © 2016. Published by Elsevier B.V.

    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[Γ], where h is a finite-dimensional Lie algebra over C, Γ 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.

    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.

  10. Autonomous solutions for powering wireless sensor nodes in rivers

    NASA Astrophysics Data System (ADS)

    Kamenar, E.; Maćešić, S.; Gregov, G.; Blažević, D.; Zelenika, S.; Marković, K.; Glažar, V.

    2015-05-01

    There is an evident need for monitoring pollutants and/or other conditions in river flows via wireless sensor networks. In a typical wireless sensor network topography, a series of sensor nodes is to be deployed in the environment, all wirelessly connected to each other and/or their gateways. Each sensor node is composed of active electronic devices that have to be constantly powered. In general, batteries can be used for this purpose, but problems may occur when they have to be replaced. In the case of large networks, when sensor nodes can be placed in hardly accessible locations, energy harvesting can thus be a viable powering solution. The possibility to use three different small-scale river flow energy harvesting principles is hence thoroughly studied in this work: a miniaturized underwater turbine, a so-called `piezoelectric eel' and a hybrid turbine solution coupled with a rigid piezoelectric beam. The first two concepts are then validated experimentally in laboratory as well as in real river conditions. The concept of the miniaturised hydro-generator is finally embedded into the actual wireless sensor node system and its functionality is confirmed.

  11. 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.

    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.

    As renewable generation has become less expensive during recent decades, and it becomes more accepted by the global population, the focus on renewable generation has expanded to include new types with promising future applications, such as river and tidal generation. Although the utilization of power electronics and electric machines in industry is phenomenal, the emphasis on system design is different for various sectors of industry. In precision control, robotics, and weaponry, the design emphasis is on accuracy and reliability with less concern for the cost of the final product. In energy generation, the cost of energy is the prime concern; thus, capital expenditures (CAPEX) and operations and maintenance expenditures (OPEX) are the major design objectives. This paper describes the electrical power conversion aspects of river and tidal generation. Although modern power converter control is available to control the generation side, the design was chosen on the bases of minimizing the CAPEX and OPEX; thus, the architecture is simple and modular for ease of replacement and maintenance. The power conversion is simplified by considering a simple diode bridge and a DC-DC power converter to take advantage of abundant and low-cost photovoltaic inverters that have well-proven grid integration characteristics (i.e., the capability to produce energy with good power quality and control real power and voltage on the grid side).

  10. Controls on morphological variability and role of stream power distribution pattern, Yamuna River, western India

    Understanding the controls on the morphological variability of river systems constitutes one of the fundamental questions in geomorphic investigation. Channel morphology is an important indicator of river processes and is of significance for mapping the hydrology-ecologic connectivity in a river system and for predicting the future trajectory of river health in response to external forcings. This paper documents the spatial morphological variability and its natural and anthropogenic controls for the Yamuna River, a major tributary of the Ganga River, India. The Yamuna River runs through a major urban centre i.e. Delhi National Capital Region. The Yamuna River was divided into eight geomorphically distinct reaches on the basis of the assemblages of geomorphic units and the association of landscape, valley and floodplain settings. The morphological variability was analysed through stream power distribution and sediment load data at various stations. Stream power distribution of the Yamuna River basin is characterised by a non-linear pattern that was used to distinguish (a) high energy ‘natural' upstream reaches, (b) ‘anthropogenically altered', low energy middle stream reaches, and (c) ‘rejuvenated' downstream reaches again with higher stream power. The relationship between stream power and channel morphology in these reaches was integrated with sediment load data to define the maximum flow efficiency (MFE) as the threshold for geomorphic transition. This analysis supports the continuity of river processes and the significance of a holistic, basin-scale approach rather than isolated local scale analysis in river studies.

    The horsefly (Diptera: Tabanidae) fauna of Jordan consists of 21 species belonging to seven genera. The present study adds 17 new records to this little-known group of haematophagous insects. Most of the new records were collected from several localities within the Jordan Valley. These new records are Chrysops flavipes Meigen, Atylotus farinosus (Szilády), Dasyrhamphis umbrinus (Meigen), Haematopota coronata Austen, Hybomitra decora (Loew), Hybomitra mendica (Villeneuve), Tabanus accensus Austen, T. albifacies Loew, T. bifarius Loew, T. darimonti Leclercq, T. laetetinctus Becker, T. leleani Austen, T. pallidipes Austen, T. regularis Jaennicke, T. rupinae Austen, T. sufis Jaennicke and Therioplectes tunicatus (Szilády). Tabanus albifacies and T. sufis were the most common species collected by hand nets (19.85% and 17.73%, respectively) and D. umbrinus, Haematopota minuscula Austen, and Haematopota coronata were the least common species (0.12% for each). Zoogeographical analysis of the recorded species showed that 12 species are of Mediterranean origin, four are of Afrotropical origin, two of European origin and at least three species can be considered as endemic to the Middle East.

  14. Capacity of river networks to buffer thermal impacts of power plants in the northeastern US

    Water temperature is a fundamental variable that influences an array of ecosystem processes including nutrient uptake, leaf breakdown, biological production, and habitat. Water temperatures can be altered by warm effluent flows from thermoelectric power plants but these impacts are often mitigated over distances downstream due to temperature re-equilibration with atmospheric conditions. We assessed the mitigation capacity of rivers in the northeastern U.S, a region with a high density of power plants, using a water temperature model developed within the Framework for Aquatic Modeling in the Earth System (FrAMES) coupled with the Thermoelectric Power Plant Model (TPPM). The spatially distributed river network model predicts average daily water temperatures at a 3-minute river grid resolution, accounting for the mixing of terrestrial runoff, power plant withdrawals, heat loading, and re-equilibration of temperatures in rivers based on solar radiation, air temperature, and hydraulic dimensions. Average predicted water temperatures match daily observations well with an average Index of Agreement (d) of 0.81 for 68 stations (2000 - 2010). Model results suggest power plants increase the total length of rivers exceeding a threshold temperature of 20 degrees Celsius by less than 1% when the re-equilibration in rivers is considered. Without the natural capacity of river temperature re-equilibration with atmospheric conditions power plants increase the total annual length of warm habitats by 15%. This highlights the buffering capacity of river networks to mitigate anthropogenic impacts to the system, representing an important ecosystem service performed by rivers in the northeast.

  15. Water-power resources of Crystal River, Colorado

    Lawrence, Fred Forrest

    1953-01-01

    The Crystal River drains the western slope of the Elk Mountains, a relatively small range in the southern Rocky Mountain province, and flows into the Roaring Fork 13 miles southeast of Glenwood Springs, Colo. The lower 7 miles of the valley is cultivated, but upstream from this stretch the valley is narrow and is used mainly for summer grazing and recreation. Above the mouth of Thompson Creek, numerous dam sites are available, but the narrow valley and steep gradient do not favor storage for regulation of streamflow. The potential power from the natural flow of the stream in an average year is estimated to be 4,750 kilowatts for 95 percent of the time; 5,102 kw for 90 percent of the time; 10,570 kw for 50 percent of the time; and 36,940 kw at mean flow. Using the regulated flow resulting from the utilization of reservoirs at Marble and Redstone, the potential power is estimated to be 26,510 kw for 90 percent of the time and 27,810 kw for 50 percent of the time.

    A number of geophysical investigations have been undertaken in the Hashemite Kingdom of Jordan to provide data for understanding the tectonic framework, the pattern of seismicity, earthquake hazards and geothermal resources of the country. Both the historical seismic record and the observed recent seismicity point to the dominance of the Dead Sea Rift as the main locus of seismic activity but significant branching trends and gaps in the seismicity pattern are also seen. A wide variety of focal plane solutions are observed emphasizing the complex pattern of fault activity in the vicinity of the rift zone. Geophysical investigations directed towards the geothermal assessment of the prominent thermal springs of Zerga Ma'in and Zara are not supportive of the presence of a crustal magmatic source. ?? 1990.

  4. Raft River 5MW Power Plant: a small binary power plant

    SciTech Connect

    Whitbeck, J.F.; DiBello, E.G.; Walrath, L.F.

    1982-01-01

    The Raft River 5MW power plant is a binary cycle pilot plant. The system uses isobutane in a dual boiling cycle. This cycle was selected because the well field and temperatures were not well known at the time of cycle selection, and therefore, a boiling cycle was desirable. The dual boiling feature provides about 15 to 20% more power and makes the output less sensitive to changes in geothermal temperature changes than a single boiler system. The plant design was based upon a 290F geothermal fluid temperature at the inlet to the plant and has a gross nominal generator rating of 5MW; however, actual output will vary according to ambient wet bulb temperatures over a range from 4.4MW to 6.2MW with the actual plant inlet temperature of 278F being obtained. The plant is supplied by three production wells. Geothermal fluid boost pumps within the plant inlet provide the pressure necessary to overcome plant pressure drop and return the fluid to the two injection sites. All long runs of the buried geothermal piping external to the plant boundaries use cement-asbestos pipe. The physical size and manpower requirements for the Raft River facility, the economics of small plant operation, and operational experience are discussed.

    As renewable generation has become less expensive during recent decades, and it becomes more accepted by the global population, the focus on renewable generation has expanded to include new types with promising future applications, such as river and tidal generation. The input variations to these types of resources are slower but also steadier than wind or solar generation. The level of water turbulent flow may vary from one place to another, however, the control algorithm can be adjusted to local environment. This paper describes the hydrokinetic aspects of river and tidal generation based on a river and tidal generator. Although the information given in this paper is not that of an exact generator deployed on site, the data used is representative of a typical river or tidal generator. In this paper, the hydrokinetic and associated electrical controller of the system were not included; however, the focus of this paper is on the hydrodynamic control.

    In 2003, the US Army Corps of Engineers initiated the Pallid Sturgeon Population Assessment Program (PSPAP) to monitor pallid sturgeon and the fish community of the Missouri River. The power analysis of PSPAP presented here was conducted to guide sampling design and effort decisions. The PSPAP sampling design has a nested structure with multiple gear subsamples within a river bend. Power analyses were based on a normal linear mixed model, using a mixed cell means approach, with variance estimates from the original data. It was found that, at current effort levels, at least 20 years for pallid and 10 years for shovelnose sturgeon is needed to detect a 5% annual decline. Modified bootstrap simulations suggest power estimates from the original data are conservative due to excessive zero fish counts. In general, the approach presented is applicable to a wide array of animal monitoring programs.

    Occupational fatalities are a worldwide problem. Certain occupations pose a greater risk than others. Recent statistics on global occupational injuries and diseases that might lead to temporary or permanent disability and even worse might lead to death, are staggering. The purpose of this study was to estimate the death rates from occupational injuries in Jordan over a period of four years; to estimate occupational fatality rate that results from accidental injuries and identify the most risky concurrent occupations with the type of injuries, the age and nationality of the victims. A total of 88 work related fatalities were admitted to three hospitals in Amman through 2008-2012 and were examined by a forensic (occupational) physician at the time. They were categorized according to, age, nationality, occupation, type of injury and were all tested for toxic substances. The occupation with the most fatalities was construction (44%); falling from a height was the commonest type of accident (44%) and head injuries were the leading injury type (21.6%); 9.1% of the deaths were positive for alcohol. Moreover, 22.7% of deaths were between ages of 25-29. Consequently, the mean occupational fatality rate was 2 per 100.000 workers during 2008-2012. Constructions and other types of occupations are more extensive problems than what is usually anticipated, especially when safety precautions are not effective or implemented. They may cause injuries and death, which will have a socioeconomic burden on families, society, governments and industries. Not to mention the grief that is associated with the death of a worker at his work site to all concerned parties. Copyright © 2014 Elsevier Ltd and Faculty of Forensic and Legal Medicine.

  13. Wadi Rum, Jordan

    NASA Image and Video Library

    2017-09-27

    NASA image acquired July 27, 2001 In southwestern Jordan lies an unusual landscape. Mountains of granite and sandstone rise next to valleys filled with red sand. Some of the mountains reach a height of about 1,700 meters (5,600 feet) above sea level, and many have near-vertical slopes. So alien is this landscape, it’s nicknamed “Valley of the Moon,” and it has served as the film set for a movie about Mars. Yet nomadic people have lived here for thousands of years. Declared a protected area in 1998, this unearthly landscape is Wadi Rum. The Advanced Land Imager (ALI) on NASA’s Earth Observing-1 (EO-1) satellite captured this natural-color image on July 27, 2001. The scene includes part of Wadi Rum and an adjacent area to the east. East of the protected area, fields with center-pivot irrigation make circles of green and brown (image upper right). As the earth tones throughout the image attest, the area is naturally arid, receiving little annual precipitation and supporting only sparse vegetation. Between rocky peaks, the sandy valleys range in color from beige to brick. Ancient granite rocks dating from the Precambrian underlie younger rocks, and some of these basement rocks have eroded into rugged, steep-sloped mountains. The granite mountains have risen thanks partly to crisscrossing fault lines under the park. Overlying the granite are sandstones from the Cambrian and Ordovician Periods, as well as loose sands. Lawrence of Arabia, who fought in the Arab Revolt of 1917–1918, made frequent references to Wadi Rum in his book The Seven Pillars of Wisdom. Likewise, a prominent feature of the protected area is named after the book. Several popular sites in Wadi Rum bear Lawrence of Arabia’s name, but whether he actually visited those sites is uncertain.

    1996-12-31

    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 the Northeastern U.S., the most costly damages from intense storm events were impacts to road-stream crossings. In steep post-glacial terrain, erosion by floodwater and entrained sediment is the largest destructive force during intense storms, and the most likely driver of major morphological changes to riverbanks and channels. Steam power analysis is a tool that can successfully quantify floodwater energy that caused damage afterward, however, prediction of which reaches or watersheds may experience future impacts remains uncertain. We must better determine how states with thousands of river miles may better prioritize flood mitigation studies, crossing replacements, or other infrastructure upgrades for future flood resilience within resource constraints. This challenged us to develop a statewide-scale scientific method for screening waterways and translating the results into effective policies for river corridor management. Here we present a method based on stream power analysis using widely-available 10-m DEMs and stream flow data to identify locations with extreme high or low stream power values (i.e., >300 W⁄m2 or <60 W⁄m2) or abrupt changes in these values. We used this information to identify potential areas of erosion or deposition in the Deerfield River watershed in Massachusetts and Vermont, then compared it to areas where damage occurred during Tropical Storm Irene. We show that areas of increasing (with respect to distance downstream) and high stream power are prone to landslides, bank failures, and other pulse sediment inputs in flood events. These are also the focal points of wood input to rivers, which combined with increased sediment load, makes culverts in these reaches especially prone to failure. Integration of this information into state databases allows communities to prioritize and make land-use decisions that are informed by the fluvial geomorphic workings of the larger watershed, but that have powerful local implications.

  20. Fish vs. power: Remaking salmon, science and society on the Fraser River, 1900--1960

    NASA Astrophysics Data System (ADS)

    Evenden, Matthew Dominic

    Overlapping resource demands made the Fraser River a contested site of development politics in twentieth century British Columbia. Since the turn of the century, power interests surveyed the river's flow, sited dams and promoted development schemes. Fisheries interests, on the other hand, sought to maintain the river as salmon spawning habitat. They questioned the necessity of dams, supported fisheries research and rehabilitation and organized anti-development coalitions. Before the mid-1950s a number of dam projects proceeded on Fraser tributaries and major landslides at Hells Gate modeled the dangers of main stem development. Because of the concerted political lobbying of fisheries groups, the skeptical appraisal of fisheries scientists to development proposals and the legal and political authority of the federal Department of Fisheries and the International Pacific Salmon Fisheries Commission, major dam projects were defeated on the Fraser in the late 1950s. Delayed development on the Fraser helped to spur hydroelectric projects on other rivers in the province; the fish-power problem on the Fraser altered the province's spatial economy of power. Once development began on the Columbia and Peace Rivers, the Fraser was protected by implication. The study combines approaches from environmental history, the history of science and political economy to demonstrate the intersections and interactions between nature, knowledge and society. Research was conducted at eleven archives in Canada and the United States in the papers of organizations, corporations, government departments, politicians, scientists and individuals.

    1964-01-01

    The Jordan Valley occupies about 400 square miles in the central part of Salt Lake County in north-central Utah. Salt Lake City, the capital of Utah, is in the northeastern part of the valley. The valley is at the eastern margin of the Basin and range physiographic province, and it is bounded on the northeast, east, south, and west by mountain ranges. The valley is drained by the Jordan River which enters through a water gap in the mountains to the south, flows north, and empties into the Great Salt Lake, which forms the northwestern border of the valley.

  6. Challenges for Implementing Salinity Gradient Energy Power Plants at River Mouths

    NASA Astrophysics Data System (ADS)

    Salinity gradient energy (SGE) is the clean and renewable energy that can be obtained from the controlled mixing of two waters with different salt concentration. River mouths, where fresh water mixes with seawater, are manifest locations for harnessing SGE, since these systems provide the sought salinity gradients, abundant water resources worldwide and are usually located close to cities and industries. The advances in research and development of the technologies for harnessing this energy source have been huge in the last decade, however, still several challenges have to be faced before its commercial implementation at river mouths. Here we present a comprehensive analysis of the factors inherent to the river mouths that restrict the exploitation of SGE in those systems, including: (i) the effects of the stratification and the water quality on the technical suitability of the systems; (ii) the limitations on the freshwater extraction for ensuring the sustainability of the river mouths; and (iii) the effect of the spatio-temporal variability of the salinity structure on the reliability of the power plants. This analysis was carried out at global scale for almost thousand river mouths and in a more detailed scale for the Magdalena River mouth (Colombia). For the global scale, the main results show that (i) 49% of the analyzed systems are suitable locations for harnessing SGE; (ii) 625 TWh/y are extractable from river mouths worldwide; (iii) the average capacity factor of SGE plants at river mouths is 84%; and (iv) 286 systems in 64 countries have a potential capacity of 10 MW or greater. Meanwhile, for the local scale, the results show that the water quality may be the most important factor limiting the site-specific potential. Despite the limitations, the SGE generation at river mouths shows to be a promising alternative energy source in the mid-term.

    This study investigates why developing states that profess to follow free market principles continue to intervene in their economies. The study investigates the extent to which the state in Jordan has penetrated its most potentially productive economic sector - the extractive mineral industry (phosphates, potash, fertilizers, cement, and the refining of oil). The study examined Jordan's [open quotes]Big 5[close quotes] companies: the Jordan Cement Factories Company, the Jordan Phosphate Mines Company, the Jordan Petroleum Refinery Company, the Arab Potash Company, and the Jordan Fertilizer Industries Company. This examination sought to reveal the political factors that give rise to an interventionist state and that sustain intervention over time. The study discusses the political nature of building a national economy in a society with limited resources and in which certain groups and classes are favored over others. In Jordan the absence of a real entrepreneurial class or vibrant private sector prompted the state to enter the economy in order to construct its economic infrastructure. This is evidenced in the establishment of Jordan's extractive minerals companies. Through its links to these companies, the state crafted an economy in which the role of labor is weak and economic power is still situated within the organs of the state. Centralized authority within the kingdom and the various policy networks linking the state to industry make it difficult for the state to withdraw from the economy. Regional and international factors reinforce this tendency. A review of these companies' activities from 1970 to 1989 reveals the political contours of state capitalism and demonstrates why the private sector has not taken hold in many small developing nations. This study analyzes the institutional environment in which public officials act. The study concludes that the state's room to maneuver within the political arena and the economy is quite substantial.

    Water resource management (WRM) through dams or reservoirs is worldwide necessary to support key human-related activities, ranging from hydropower production to water allocation and flood risk mitigation. Designing of reservoir operations aims primarily to fulfill the main purpose (or purposes) for which the structure has been built. However, it is well known that reservoirs strongly influence river geomorphic processes, causing sediment deficits downstream, altering water, and sediment fluxes, leading to riverbed incision and causing infrastructure instability and ecological degradation. We propose a framework that, by combining physically based modeling, surrogate modeling techniques, and multiobjective (MO) optimization, allows to include fluvial geomorphology into MO optimization whose main objectives are the maximization of hydropower revenue and the minimization of riverbed degradation. The case study is a run-of-the-river power plant on the River Po (Italy). A 1-D mobile-bed hydro-morphological model simulated the riverbed evolution over a 10 year horizon for alternatives operation rules of the power plant. The knowledge provided by such a physically based model is integrated into a MO optimization routine via surrogate modeling using the response surface methodology. Hence, this framework overcomes the high computational costs that so far hindered the integration of river geomorphology into WRM. We provided numerical proof that river morphologic processes and hydropower production are indeed in conflict but that the conflict may be mitigated with appropriate control strategies.

  9. 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.

    2016-10-01

    Worldwide riverine thermal pollution patterns were investigated by combining mean annual heat rejection rates from power plants with once-through cooling systems with the global hydrological-water temperature model variable infiltration capacity (VIC)-RBM. The model simulates both streamflow and water temperature on 0.5° × 0.5° spatial resolution worldwide and by capturing their effect, identifies multiple thermal pollution hotspots. The Mississippi receives the highest total amount of heat emissions (62% and 28% of which come from coal-fuelled and nuclear power plants, respectively) and presents the highest number of instances where the commonly set 3 °C temperature increase limit is equalled or exceeded. The Rhine receives 20% of the thermal emissions compared to the Mississippi (predominantly due to nuclear power plants), but is the thermally most polluted basin in relation to the total flow per watershed, with one third of its total flow experiencing a temperature increase ≥5 °C on average over the year. In other smaller basins in Europe, such as the Weser and the Po, the share of the total streamflow with a temperature increase ≥3 °C goes up to 49% and 81%, respectively, during July-September. As the first global analysis of its kind, this work points towards areas of high riverine thermal pollution, where temporally finer thermal emission data could be coupled with a spatially finer model to better investigate water temperature increase and its effect on aquatic ecosystems.

    Criminal attacks by burns on women in Jordan are highlighted in this retrospective study carried out of all proved cases of criminal burns in female patients treated at the burn unit of the Royal Rehabilitation Center in Jordan between January 2005 and June 2012. Thirteen patients were included in our study, out of a total of 550 patients admitted, all in the age range of 16-45 yr. Of these 13 women, six were burned by acid throwing, five by hot water, and two by direct flames from fuel thrown over them. Burn percentage ranged from 15 to 75% of the total body surface area, with involvement in most cases of the face and upper trunk. The mean hospital stay was 33 days and the mortality rate was 3/13, i.e. 23%. Violence against women exists in Jordanian society, yet burning assaults are rare. Of these, burning by throwing acid is the most common and most disfiguring act, with a higher mortality rate in domestic environments.

  15. Stream power controls the braiding intensity of submarine channels similarly to rivers

    We use physical experiments to investigate the response of submarine braided channels driven by saline density currents to increasing inflow discharge and bed slope. We find that, similarly to braided rivers, only a fraction of submarine braided networks have active sediment transport. We then find similar response to imposed change between submarine and fluvial braided systems: (1) both the active and total braiding intensities increase with increasing discharge and slope; (2) the ratio of active braiding intensity to total braiding intensity is 0.5 in submarine braided systems regardless of discharge and slope; and (3) the active braiding intensity scales linearly with dimensionless stream power. Thus, braided submarine channels and braided rivers are similar in some important aspects of their behavior and responses to changes in stream power and bed slope. In light of the scale independence of braided channel planform organization, these results are likely to apply beyond experimental scales.

  16. The Effects of Run-of-River Hydroelectric Power Schemes on Fish Community Composition in Temperate Streams and Rivers

    PubMed Central

    2016-01-01

    The potential environmental impacts of large-scale storage hydroelectric power (HEP) schemes have been well-documented in the literature. In Europe, awareness of these potential impacts and limited opportunities for politically-acceptable medium- to large-scale schemes, have caused attention to focus on smaller-scale HEP schemes, particularly run-of-river (ROR) schemes, to contribute to meeting renewable energy targets. Run-of-river HEP schemes are often presumed to be less environmentally damaging than large-scale storage HEP schemes. However, there is currently a lack of peer-reviewed studies on their physical and ecological impact. The aim of this article was to investigate the effects of ROR HEP schemes on communities of fish in temperate streams and rivers, using a Before-After, Control-Impact (BACI) study design. The study makes use of routine environmental surveillance data collected as part of long-term national and international monitoring programmes at 23 systematically-selected ROR HEP schemes and 23 systematically-selected paired control sites. Six area-normalised metrics of fish community composition were analysed using a linear mixed effects model (number of species, number of fish, number of Atlantic salmon—Salmo salar, number of >1 year old Atlantic salmon, number of brown trout—Salmo trutta, and number of >1 year old brown trout). The analyses showed that there was a statistically significant effect (p<0.05) of ROR HEP construction and operation on the number of species. However, no statistically significant effects were detected on the other five metrics of community composition. The implications of these findings are discussed in this article and recommendations are made for best-practice study design for future fish community impact studies. PMID:27191717

    As with all large rivers in the United States, the Missouri River has been altered, with approximately one-third of the mainstem length impounded and one-third channelized. These physical alterations to the environment have affected the fish populations, but studies examining the effects of alterations have been localized and for short periods of time, thereby preventing generalization. In response to the U.S. Fish and Wildlife Service Biological Opinion, the U.S. Army Corps of Engineers (USACE) initiated monitoring of habitat improvements of the Missouri River in 2005. The goal of the Habitat Assessment Monitoring Program (HAMP) is to provide information on the response of target fish species to the USACE habitat creation on the Lower Missouri River. To determine the statistical power of the HAMP and in cooperation with USACE, a power analysis was conducted using a normal linear mixed model with variance component estimates based on the first complete year of data. At a level of 20/16 (20 bends with 16 subsamples in each bend), at least one species/month/gear model has the power to determine differences between treated and untreated bends. The trammel net in September had the most species models with adequate power at the 20/16 level and overall, the trammel net had the most species/month models with adequate power at the 20/16 level. However, using only one gear or gear/month combination would eliminate other species of interest, such as three chub species (Macrhybopsis meeki, Macrhybopsis aestivalis, and Macrhybopsis gelida), sand shiners (Notropis stramineus), pallid sturgeon (Scaphirhynchus albus), and juvenile sauger (Sander canadensis). Since gear types are selective in their species efficiency, the strength of the HAMP approach is using multiple gears that have statistical power to differentiate habitat treatment differences in different fish species within the Missouri River. As is often the case with sampling rare species like the pallid sturgeon, the

    Run-of-river (ROR) hydroelectric power (HEP) schemes are often presumed to be less ecologically damaging than large-scale storage HEP schemes. However, there is currently limited scientific evidence on their ecological impact. The aim of this article is to investigate the effects of ROR HEP schemes on communities of invertebrates in temperate streams and rivers, using a multi-site Before-After, Control-Impact (BACI) study design. The study makes use of routine environmental surveillance data collected as part of long-term national and international monitoring programmes at 22 systematically-selected ROR HEP schemes and 22 systematically-selected paired control sites. Five widely-used family-level invertebrate metrics (richness, evenness, LIFE, E-PSI, WHPT) were analysed using a linear mixed effects model. The analyses showed that there was a statistically significant effect (p<0.05) of ROR HEP construction and operation on the evenness of the invertebrate community. However, no statistically significant effects were detected on the four other metrics of community composition. The implications of these findings are discussed in this article and recommendations are made for best-practice study design for future invertebrate community impact studies.

  2. River longitudinal profiles and bedrock incision models: Stream power and the influence of sediment supply

    NASA Astrophysics Data System (ADS)

    Sklar, Leonard; Dietrich, William E.

    The simplicity and apparent mechanistic basis of the stream power river incision law have led to its wide use in empirical and theoretical studies. Here we identify constraints on its calibration and application, and present a mechanistic theory for the effects of sediment supply on incision rates which spotlights additional limitations on the applicability of the stream power law. On channels steeper than about 20%, incision is probably dominated by episodic debris flows, and on sufficiently gentle slopes, sediment may bury the bedrock and prevent erosion. These two limits bound the application of the stream power law and strongly constrain the possible combination of parameters in the law. In order to avoid infinite slopes at the drainage divide in numerical models of river profiles using the stream power law it is commonly assumed that the first grid cell is unchanneled. We show, however, that the size of the grid may strongly influence the calculated equilibrium relief. Analysis of slope-drainage area relationships for a river network in a Northern California watershed using digital elevation data and review of data previously reported by Hack reveal that non-equilibrium profiles may produce well defined slope-area relationships (as expected in equilibrium channels), but large differences between tributaries may point to disequilibrium conditions. To explore the role of variations in sediment supply and transport capacity in bedrock incision we introduce a mechanistic model for abrasion of bedrock by saltating bedload. The model predicts that incision rates reach a maximum at intermediate levels of sediment supply and transport capacity. Incision rates decline away from the maximum with either decreasing supply (due to a shortage of tools) or increasing supply (due to gradual bed alluviation), and with either decreasing transport capacity (due to less energetic particle movement) or increasing transport capacity (due less frequent particle impacts per unit bed

    Hydropower is the major renewable electricity generation technology worldwide. The future expansion of this technology mostly relies on the development of small run-of-river projects, in which a fraction of the running flows is diverted from the river to a turbine for energy production. Even though small hydro inflicts a smaller impact on aquatic ecosystems and local communities compared to large dams, it cannot prevent stresses on plant, animal, and human well-being. This is especially true in mountain regions where the plant outflow is located several kilometers downstream of the intake, thereby inducing the depletion of river reaches of considerable length. Moreover, the negative cumulative effects of run-of-river systems operating along the same river threaten the ability of stream networks to supply ecological corridors for plants, invertebrates or fishes, and support biodiversity. Research in this area is severely lacking. Therefore, the prediction of the long-term impacts associated to the expansion of run-of-river projects induced by global-scale incentive policies remains highly uncertain. This contribution aims at providing objective tools to address the preliminary choice of the capacity of a run-of-river hydropower plant when the economic value of the plant and the alteration of the flow regime are simultaneously accounted for. This is done using the concepts of Pareto-optimality and Pareto-dominance, which are powerful tools suited to face multi-objective optimization in presence of conflicting goals, such as the maximization of the profitability and the minimization of the hydrologic disturbance induced by the plant in the river reach between the intake and the outflow. The application to a set of case studies belonging to the Piave River basin (Italy) suggests that optimal solutions are strongly dependent the natural flow regime at the plant intake. While in some cases (namely, reduced streamflow variability) the optimal trade-off between economic

    Power levels available from the kinetic energy of tidal flows can be significant in coastal or estuarine regions with relatively modest tidal ranges. For example, the central Maine coast, where the mean semidiurnal tidal range is about 3 m, includes several river estuaries with narrow interconnecting passages where tidal currents exceed 2 m s-1. A numerical circulation model applied to this region shows that the vigorous tidal flows lead to available power peaks exceeding 3 Kw per square meter of turbine aperture in several sites during a spring tide. At one promising location, the peak power density is 6.5 Kw/m2 near the surface and the energy capacity in a 500 m2 section under mean tidal conditions is about 2700 Mwh per year, sufficient to meet the average consumption needs of about 150 homes connected to an electrical grid capable of accepting the tidal power pulses and blending them with traditional sources.

    Colorectal cancer (CRC) ranked first among cancers reported in males and second among cancers reported in females in Jordan in 2010. There has been no specific CRC-control programme in Jordan. Additionally, there has been no published study from Jordan or its neighbours on patient delays in presentation, diagnosis or treatment. Therefore, we conducted this study to assess these important quality indicators aiming to improve prognosis for CRC and to provide baseline data for future health promotion programmes for CRC in Jordan. This project was a cross-sectional study on CRC patients at Al Bashir Hospital, Ministry of Health, and at the Military Oncology Centre of the Jordanian Royal Medical Services. The total number of participants was 189. The proportion of patients with presentation delay, diagnosis delay or treatment delay was 33.9, 68.1 and 32.6%, respectively. The main reasons reported for delay in presentation were lack of knowledge that symptoms were suggestive of cancer (58.5%), misdiagnosis by physicians or pharmacists (38.4%) or the patient did not want to visit a doctor (3.1%). Predictors of delay and mean time for presentation, diagnosis and treatment were identified. Our results revealed that CRC patients in Jordan experience delays in presentation, Powered by Editorial Manager® and ProduXion Manager® from Aries Systems Corporation diagnosis, and, to a lesser degree, in treatment. This could justify the advanced stages at diagnosis and poor outcomes for CRC patients. Our findings provide baseline information for future CRC-control programmes in Jordan. We recommend that CRC prevention programmes in Jordan focus on early detection of CRC and target both patients and physicians.

    We conducted an independent survey of tobacco use in Jordan following the methods and template of the Global Adult Tobacco Survey. Using data collected on cigarette use and cigarette prices, we estimated the price elasticity of cigarette demand in Jordan. We used a 2-part model of cigarette demand. In the first part, we estimate the impact of prices on the decision to smoke while controlling for individual demographic and environmental characteristics. Conditional on smoking, we then estimate the effect of price on the number of cigarettes smoked. The total price elasticity of cigarette demand in Jordan was estimated to be -0.6. Smoking among women was found to be relatively unresponsive to price (elasticity of -0.01), whereas smoking among men was much more responsive to price (elasticity of -0.81). The price elasticity estimates suggest that significant increases in tobacco taxes are likely to be effective in reducing smoking in Jordan, particularly smoking among men.

    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

    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.

  11. Generalized Conformal and Superconformal Group Actions and Jordan Algebras

    NASA Astrophysics Data System (ADS)

    We study the "conformal groups" of Jordan algebras along the lines suggested by Kantor. They provide a natural generalization of the concept of conformal transformations that leave two-angle invariant to spaces where "p-angle" (p ≥ 2) can be defined. We give an oscillator realization of the generalized conformal groups of Jordan algebras and Jordan triple systems. A complete list of the generalized conformal algebras of simple Jordan algebras and Hermitian Jordan triple systems is given. These results are then extended to Jordan superalgebras and super Jordan triple systems. By going to a coordinate representation of the (super)oscillators one then obtains the differential operators representing the action of these generalized (super) conformal groups on the corresponding (super) spaces. The superconformal algebras of the Jordan superalgebras in Kac's classification is also presented.

    The impact of sediment transport on the total amount of fine-grained cohesive sediment has not been elucidated at estuaries. Cesium134 and cesium137 were spread from the Fukushima Daiichi Nuclear Power Plant (FDNPP) after the earthquake of March 11 of 2011, and attached to the fine-grained sand on the land. The contaminated sand flowed into the river mouths through the rivers possibly due to the complex physical processes in estuarine areas. To evaluate the fine-grained sediment transport around Tokyo Bay, field observations were carried out utilizing the sediment core of radionuclides originated from FDNPP as an effective tracer. The cohesive sediment transport at three different river mouths around Tokyo was successfully quantified every 3 months. The cohesive sediment transport deposited in the estuary was found to be dependent on the land use, geometry, river discharge and salinity. As a result, most of a sediment transport occurred in 2011. This sediment accumulated near the river mouth depending on the river discharge at rain fall events. Each flux of sediment was shown by this observation results including run-off from water shed, flux of rivers and stocks in rivers and the bay.

    Rivers are both the means and the routes by which the products of continental weathering are carried to the oceans of the world. Except in the most arid areas more water falls as precipitation than is lost by evaporation and transpiration from the land surface to the atmosphere. Thus there is an excess of water, which must flow to the ocean. Rivers, then, are the routes by which this excess water flows to the ultimate base level. The excess of precipitation over evaporation and transpiration provides the flow of rivers and springs, recharges ground-water storage, and is the supply from which man draws water for his needs.

    Investigations have continued into the possibility that significant information on stream flow rates can be obtained from aerial and satellite imagery of river meander patterns by seeking a correlation between the meander and discharge spectra of rivers. Such a correlation could provide the basis for a simple and inexpensive technique for remote sensing of the water resources of large geographical areas, eliminating the need for much hydrologic recording. The investigation of the nature of the meander and discharge spectra and their interrelationship can also contribute to a more fundamental understanding of the processes of both river meander formation and drainage of large basins. It has been found that floods decay with an inverse power law dependence on time. The exponent of this dependence varies from river to river and even from station to station along the same river. This power law time dependence makes possible the forecasting of river discharge with an uncertainty of about 5% for as long as a month following the flood peak.

    Sediment transport at river mouths, which consists of suspended-load and bed-load, has not been fully understood, since bed-load transport of cohesive sand is difficult to observe. Especially, the impact of sediment transport on the total amount of fine-grained cohesive sediment has not been elucidated. Cesium-134 and cesium-137 were spread from the Fukushima Daiichi Nuclear Power Plant (FDNPP) after the earthquake of March 11 of 2011, and attached to the fine-grained sand on the land. The contaminated sand flowed into the river mouths through the rivers possibly due to the complex physical processes in estuarine areas. To evaluate the fine-grained sediment transport around Tokyo and Tokyo Bay, field observations were carried out utilizing radionuclide originated from FDNPP as an effective tracer. The cohesive sediment transport at three different river mouths around Tokyo was successfully quantified. The cohesive sediment transport deposited in the estuary was found to be greatly dependent on the land use, geometry, river discharge and salinity. In addition,the transport driven by the rainfall was minute, and its behavior was quite different from suspended solids. Although further field observations of radionuclide are necessary, it is clear that fine-grained sediment in the bay from rivers already settled on the river mouth by aggregation. The settled sand will not move even in rainfall events. Consequently, the transport of radionuclide to the Pacific Ocean may not occur.; Cesium distribution around Tokyo Bay ; Cesium Concentration in Edogawa river

    As demand for electricity increases, investments into new generation capacity from renewable and nonrenewable sources should include assessment of global (climate) change consequences not just of the operational phase of the power plants but construction effects as well. In this paper, the global warming effect (GWE) associated with construction and operation of comparable hydroelectric, wind, solar, coal, and natural gas power plants is estimated for four time periods after construction. The assessment includes greenhouse gas emissions from construction, burning of fuels, flooded biomass decay in the reservoir, loss of net ecosystem production, and land use. The results indicate that a wind farm and a hydroelectric plant in an arid zone (such as the Glen Canyon in the Upper Colorado River Basin) appear to have lower GWE than other power plants. For the Glen Canyon hydroelectric plant, the upgrade 20 yr after the beginning of operation increased power capacity by 39% but resulted in a mere 1% of the CO2 emissions from the initial construction and came with no additional emissions from the reservoir, which accounts for the majority of the GWE.

    To highlight the epidemiological, clinical, and pathological features of gallbladder cancer in Jordan as a model for the Middle East. Only scattered reports are available from this region. The histopathological reports and the hospital records for all cholecystectomies performed at Princess Basma Teaching Hospital between 1994-2000 were retrospectively reviewed to identify all patients with gallbladder carcinoma. All the histological slides for the cancer group were reviewed and reclassified by a single pathologist. Of 4502 cholecystectomies performed, 33 cases (0.73%) of gallbladder carcinoma were found. The mean age was 61.4 years (range 39-80 years). The male : female ratio was 1 : 3.7. Biliary colic and/or acute cholecystitis were the main presentations. Gallstones were present in 88% (29/33) of the patients. The spectrum of histological subtypes was similar to other series. Only three cases were diagnosed preoperatively, making the incidence of incidental gallbladder cancer 0.66% (30/4502). Simple cholecystectomy was performed for 13 patients. The remaining 20 patients underwent cholecystectomy and portal lymphadenectomy with (five cases) or without (15 cases) extrahepatic resection of the bile ducts. The mean follow up was 22 months (SD +/- 18.95 months; range 1-96 months). The 2-year survival rates for stages I, II, III, and IV were 100%, 42.9%, 10.8%, and 0%, respectively (P = 0.0013). The importance of a high index of suspicion when dealing with cholelithiasis in elderly patients, particularly with large sized stones, cannot be over-emphasized. Proper gross inspection in the theater should be a routine procedure performed by all surgeons. Routine ultrasound for suspected gallbladder stones should always be performed under the supervision of senior radiologists.

    Fluvial systems of the southern Laurentian Great Lakes region are carved into a complex glacial landscape shaped by continental ice and meltwater of the late Pleistocene. These glacially conditioned river catchments are typically small with drainage areas < 104 km2. A 10-m digital elevation model (DEM) is used to map the spatial distribution of stream gradient for 22 major river catchments of peninsular southern Ontario, which drain to base levels in the lower Great Lakes (Huron, St. Clair, Erie, and Ontario). Raw data from the DEM show stream gradients that exhibit multiscale variance from real and from artifact sources. Based on a vertical slice and multiple-pass moving-window averaging approach, slope data are generalised to the river reach scale (1-2 km) as a representative spatial scale for fluvial processes operating over Holocene timescales. Models of specific stream power are then compared with glacial landform and surface geology mapping. Inherited glacial signatures in river slope appear as deviations in a stream length-gradient index (SL/K index), where river reaches are frequently oversteepened or understeepened. Based on a slope-area analysis, and complementary to theories of channel pattern discrimination, constant stream power curves (with power-law exponent of - 0.4) provide a first-order approach to stratify river reaches in terms of glacial conditioning and expected planform morphologies. However, multiple-channel planform types are rare and localised in southern Ontario, indicating that oversteepened reaches with high stream powers may often be moderated by (1) sediment calibre, with cobble-beds from inherited glacial sediments; and/or (2) relative bank strength, with limited channel widening particularly in gravel and sand-bed channels. Further discrimination of glacially conditioned fluvial process domains will ultimately require consideration of alluvial floodplain characteristics in addition to general observations of river morphology and

The failure to appreciate the integral connection between floodplains and channel underlies many socioeconomic and environmental problems in river management today. However it is a difficult task of collecting reliable field hydrological data. Under such situations either synthetic or statistically generated data were used for hydraulic engineering designing and flood modeling. The fundamentals of precipitation-runoff relationship through synthetic unit hydrograph for Gin River basin were prepared using the method of the Flood Studies Report of the National Environmental Research Council, United Kingdom (1975). The Triangular Irregular Network model was constructed using Geographic Information System (GIS) to determine hazard prone zones. The 1:10,000 and 1:50,000 topography maps and field excursions were also used for initial site selection of mini-hydro power units and determine flooding area. The turbines output power generations were calculated using the parameters of net head and efficiency of turbine. The peak discharge achieves within 4.74 hours from the onset of the rainstorm and 11.95 hours time takes to reach its normal discharge conditions of Gin River basin. Stream frequency of Gin River is 4.56 (Junctions/ km2) while the channel slope is 7.90 (m/km). The regional coefficient on the catchment is 0.00296. Higher stream frequency and gentle channel slope were recognized as the flood triggering factors of Gin River basin and other parameters such as basins catchment area, main stream length, standard average annual rainfall and soil do not show any significant variations with other catchments of Sri Lanka. The flood management process, including control of flood disaster, prepared for a flood, and minimize it impacts are complicated in human population encroached and modified

    The people's perception on environmental and socio-economic impacts due to three hydro-electric projects (HEPs; commissioned and under construction) were studied in the north-west Indian Himalaya. Surveys among 140 project-affected people (PAPs) using a checklist of impacts indicate that among the negative impacts, decrease in flora/fauna, agriculture, flow of river, aesthetic beauty; and increase in water pollution, river bed quarrying for sand/stone, human settlement on river banks and social evils; and among the positive impacts, increase in standard of living, road connectivity, means of transport, public amenities, tourism and environmental awareness were related with HEPs. The PAPs tend to forget the negative impacts with the age of the HEPs after it becomes functional, and the positive impacts seem to outweigh the negative impacts. Study concludes that it is difficult to separate the compounding impacts due to HEP construction and other anthropogenic and natural factors, and in the absence of cause-and-effect analyses, it is hard to dispel the prevailing notion that HEPs are undesirable in the study area that led to agitations by the environmentalists and stopped construction of one of these HEPs. To overcome the situation, multi-disciplinary scientific studies involving the PAPs need to be carried out in planning and decision-making to make HEPs environment friendly and sustainable in this region. There is also a need to adopt low carbon electric power technologies and promote a decentralized energy strategy through joint ventures between public and private companies utilizing locally available renewable energy resources.

    The Wabash River Integrated Methanol and Power Production from Clean Coal Technologies (IMPPCCT) project is evaluating integrated electrical power generation and methanol production through clean coal technologies. The project is conducted by a multi-industry team lead previously by Gasification Engineering Corporation (GEC). The project is now under the leadership of ConocoPhillips Company (COP) after it acquired GEC and the E-Gas{trademark} gasification technology from Global Energy in July 2003. The Phase I of this project was supported by Air Products and Chemicals, Inc., Dow Chemical Company, Dow Corning Corporation, Methanex Corporation, and Siemens Westinghouse Power Corporation, while the Phase II is supported by Gas Technology Institute, TDA Research, Inc., and Nucon International, Inc. The two project phases planned for execution include: (1) Feasibility study and conceptual design for an integrated demonstration facility at Global Energy's existing Wabash River Energy Limited (WREL) plant in West Terre Haute, Indiana, and for a fence-line commercial embodiment plants (CEP) operated at Dow Chemical or Dow Corning chemical plant locations (2) Research, development, and testing (RD&T) to define any technology gaps or critical design and integration issues. The WREL facility was designed, constructed, and operated under a project selected and co-funded under the Round IV of the United States Department of Energy's (DOE's) Clean Coal Technology Program. In this project, coal and/or other solid fuel feedstocks are gasified in an oxygen-blown, entrained-flow gasifier with continuous slag removal and a dry particulate removal system. The resulting product synthesis gas is used to fuel a combustion turbine generator whose exhaust is integrated with a heat recovery steam generator to drive a refurbished steam turbine generator. The gasifier uses technology initially developed by The Dow Chemical Company (the Destec Gasification Process), and now acquired and

    Survival studies of juvenile salmonids implanted with acoustic tags have been conducted at hydroelectric dams within the Federal Columbia River Power System (FCRPS) in the Columbia and Snake rivers between 2010 and 2014 to assess compliance with dam passage survival standards stipulated in the 2008 Biological Opinion (BiOp). For juvenile salmonids migrating downstream in the spring, dam passage survival defined as survival from the upstream dam face to the tailrace mixing zone must be ≥96% and for summer migrants, ≥93%, and estimated with a standard error ≤1.5% (i.e., 95% confidence interval of ±3%). A total of 29 compliance tests have been conducted at 6 of 8 FCRPS main-stem dams, using over 109,000 acoustic-tagged salmonid smolts. Of these 29 compliance studies, 23 met the survival standards and 26 met the precision requirements. Of the 6 dams evaluated to date, individual survival estimates range from 0.9597 to 0.9868 for yearling Chinook Salmon, 0.9534 to 0.9952 for steelhead, and 0.9076 to 0.9789 for subyearling Chinook Salmon. These investigations suggest the large capital investment over the last 20 years to improve juvenile salmon passage through the FCRPS dams has been beneficial.

  6. Use Of limestone resources in flue-gas desulfurization power plants in the Ohio River Valley

    1999-01-01

    In 1994, more than 41 of the approximately 160 coal-fired, electrical- power plants within the six-state Ohio River Valley region used flue-gas desulfurization (FGD) units to desulfurize their emissions, an approximately 100% increase over the number of plants using FGD units in 1989. This increase represents a trend that may continue with greater efforts to meet Federal Clean Air Act standards. Abundant limestone resources exist in the Ohio River Valley and are accessed by approximately 975 quarries. However, only 35 of these are believed to have supplied limestone for FGD electrical generating facilities. The locations of these limestone suppliers do not show a simple spatial correlation with FGD facilities, and the closest quarries are not being used in most cases. Thus, reduction in transportation costs may be possible in some cases. Most waste generated by FGD electrical-generating plants is not recycled. However, many FGD sites are relatively close to gypsum wallboard producers that may be able to process some of their waste.

    This paper is concerned with the quantification of the likely effect of anthropogenic climate change on the water resources of Jordan by the end of the twenty-first century. Specifically, a suite of hydrological models are used in conjunction with modelled outcomes from a regional climate model, HadRM3, and a weather generator to determine how future flows in the upper River Jordan and in the Wadi Faynan may change. The results indicate that groundwater will play an important role in the water security of the country as irrigation demands increase. Given future projections of reduced winter rainfall and increased near-surface air temperatures, the already low groundwater recharge will decrease further. Interestingly, the modelled discharge at the Wadi Faynan indicates that extreme flood flows will increase in magnitude, despite a decrease in the mean annual rainfall. Simulations projected no increase in flood magnitude in the upper River Jordan. Discussion focuses on the utility of the modelling framework, the problems of making quantitative forecasts and the implications of reduced water availability in Jordan.

    Stream power represents the rate of energy expenditure along a river and can be calculated using topographic data acquired via remote sensing or field surveys. This study sought to quantitatively relate temporal changes in the form of Soda Butte Creek, a gravel-bed river in northeastern Yellowstone National Park, to stream power gradients along an 8-km reach. Aerial photographs from 1994 to 2012 and ground-based surveys were used to develop a locational probability map and morphologic sediment budget to assess lateral channel mobility and changes in net sediment flux. A drainage area-to-discharge relationship and DEM developed from LiDAR data were used to obtain the discharge and slope values needed to calculate stream power. Local and lagged relationships between mean stream power gradient at median peak discharge and volumes of erosion, deposition, and net sediment flux were quantified via spatial cross-correlation analyses. Similarly, autocorrelations of locational probabilities and sediment fluxes were used to examine spatial patterns of sediment sources and sinks. Energy expended above critical stream power was calculated for each time period to relate the magnitude and duration of peak flows to the total volumetric change in each time increment. Collectively, we refer to these methods as the stream power gradient (SPG) framework. The results of this study were compromised by methodological limitations of the SPG framework and revealed some complications likely to arise when applying this framework to small, wandering, gravel-bed rivers. Correlations between stream power gradients and sediment flux were generally weak, highlighting the inability of relatively simple statistical approaches to link sub-budget cell-scale sediment dynamics to larger-scale driving forces such as stream power gradients. Improving the moderate spatial resolution techniques used in this study and acquiring very-high resolution data from recently developed methods in fluvial remote

    Permanent neonatal diabetes mellitus (PNDM) is a rare heterogeneous form of diabetes that develops within the first 6 months of life. The objective of this study is to define the genetic etiology and incidence of permanent neonatal diabetes mellitus in Jordan. This study was conducted in Jordan at the National Center of Diabetes, Endocrinology and Genetics, Amman, between 2006 and 2012. The study included 22 cases diagnosed with diabetes within the first year of life. The incidence of PNDM in Jordan was calculated as one case for every 203,221 live births. Mutations were found in six out of ten cases diagnosed before 6 months and included one homozygous ABCC8 p.R826W mutation, three cases with a heterozygous KCNJ11 p.R201C mutation, and two cases with a homozygous EIF2AK3 splicing mutation. The genetic etiology of PNDM in Jordan is different from that seen in European countries and more similar to other Arab countries.

    The purpose of this study was to investigate the working conditions and factors related to job satisfaction among Jordanian occupational therapists. A self-administered survey consisting of several questions about the participants' jobs was developed for this study. The inclusion criteria included occupational therapists who worked in the field of occupational therapy (OT) in Jordan and who had at least six months of experience. The survey was distributed to 120 occupational therapists in different OT settings. One hundred and one occupational therapists from different hospitals, centres, schools and universities responded to the survey. Salaries of the participants were low in comparison with the salaries of the rest of healthcare practitioners in Jordan. Chi-square analysis revealed significant relationship between participants' perceived job satisfaction and the administration of the setting, and between the choice of studying OT and the salary that the participant makes. Most occupational therapists in Jordan are young, have modest experience and work in general OT services in government-owned facilities or paediatric centres. A sense of dissatisfaction was obvious among the participants. Further studies are needed to explore reasons of work satisfaction and dissatisfaction among occupational therapists in Jordan.

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

    Hamhalter, Jan

    2012-12-15

    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 Molnar.

    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

    Hemodialysis treatment is a costly procedure that requires specific resources. It has a considerable burden on patients, caregivers, and healthcare system. The aim of this study was to estimate the economic burden borne by the Ministry of Health (MOH) in Jordan, with a focus on direct medical, direct non-medical, and indirect cost. The study was conducted at MOH hospitals in Jordan, from August to November 2010. A total of 138 patients and 49 caregivers were involved in the study. An economic evaluation study was used to analyze the burden of hemodialysis treatment at MOH, Jordan. Direct medical costs were estimated through micro and macro costing from the provider's perspective. Patients' and caregivers' costs were included to calculate direct non-medical costs. Human capital approach was employed to evaluate the productivity loss for indirect cost and premature death and potential year life loss was used to estimate the premature death cost. The total burden of hemodialysis at MOH, Jordan was USD17.70 million per year. Cost per session was $72 and the annual cost per patient was $9976. Direct medical cost was $7.20 million (41%) and direct non-medical cost was $2.02 million (11%). On the other hand, indirect cost (productivity loss) was $8.48 million (48%). All 722 patients on hemodialysis at MOH hospitals consumed 2.7% of MOH budget. Costs of treating and managing patients on hemodialysis at MOH hospitals in Jordan are substantial. Therefore, efforts should be taken to slow down the progress of renal failure to save resources and a comparative study with other modalities, such as continuous ambulatory peritoneal dialysis and kidney transplantation, should be considered.

    During the routine operation, nuclear power plants discharge waste water containing a certain amount of radioactivity, whose main component is the artificial radionuclide tritium. The amounts of tritium released into the environment are kept within the legal requirements, which minimize the noxious effects of radioactivity, but the activity concentration is well measurable in surface water of the recipient. This study compares amount of tritium activity in waste water from nuclear power plants and the tritium activity detected at selected relevant sites of surface water quality monitoring. The situation is assessed in the catchment of the Vltava and Elbe Rivers, affected by the Temelín Nuclear Power Plant as well as in the Jihlava River catchment (the Danube River catchment respectively), where the waste water of the Dukovany Nuclear Power Plant is discharged. The results show a good agreement of the amount of released tritium stated by the power plant operator and the tritium amount detected in the surface water and highlighted the importance of a robust independent monitoring of tritium discharged from a nuclear power plant which could be carried out by water management authorities. The outputs of independent monitoring allow validating the values reported by a polluter and expand opportunities of using tritium as e.g. tracer. Copyright © 2017 Elsevier Ltd. All rights reserved.

    In this paper we discuss how the legitimacy of the impact assessment process is a key issue in conflict mediation in environmental impact assessment. We contrast two EIA cases in hydro-power generation plans made for the Ii River, Finland in different decades, and evaluate how impact assessment in these cases has contributed to the creation, mediation and resolution of conflicts. We focus on the elements of distributional and procedural justice that made the former EIA process more legitimate and consensual and the latter more conflictual. The results indicate that it is crucial for conflict mediation to include all the values and interests of the parties in the goal-setting process and in the definition and assessment of alternatives. The analysis also indicates that procedural justice is the most important to help the people and groups involved to accept the legitimacy of the impact assessment process: how different parties and their values and interests are recognized, and how participation and distribution of power are organized in an impact assessment process. It is confirmed in this article that SIA may act as a mediator or a forum providing a process through which competing knowledge claims, various values and interests can be discussed and linked to the proposed alternatives and interventions.

    The emission factor method was used to estimate major air pollutant emissions of coal-fired power plant in the Yangtze River Delta (YRD) region of the year 2012. Results showed that emissions of SO2, NOx, dust, PM10, PM2.5 were respectively 473 238, 1 566 195, 587 713, 348 773 and 179 820 t. For SO2 and NOx, 300 MW and above class units made contributions of 85% and 82% in emission; while in the respect of dust, PM10 and PM2.5 contribution rates of 100 MW and below class units were respectively 81%, 53% and 40%. Considering the regional distribution, Jiangsu discharged the most, followed by Zhejiang, Shanghai. According to discharge data of several local power plants, we also calculated and made a comparative analysis of emission factors in different unit levels in Shanghai, which indicated a lower emission level. Assuming an equal level was reached in whole YRD, SO2 emission would cut down 55. 8% - 65. 3%; for NOx and dust emissions were 50. 5% - 64. 1% and 3. 4% - 11. 3%, respectively. If technologies and pollution control of lower class units were improved, the emission cuts would improve. However, according to the pollution realities of YRD, we suggested to make a multiple-cuts plan, which could effectively improve the reaional atmospheric environment.

    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, φ, 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 φ 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) ≅ e{sup α{sub 1} t{sup p{sup {sub 1}}}}, as t → ∞ where α{sub 1} > 0 and 0 < p{sub 1} < 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 a(t) ≅ e{sup α{sub 2} tp{sub 2}} as t → ∞ where α{sub 2} > 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

    The Fukushima Daiichi Nuclear Power Plant accident which followed the earthquake and tsunami on 11 March 2011 resulted in the release of Cs-134 and Cs-137 into the surrounding environment, where highly elevated levels are reported. There is considerable concern about the redistribution of these radioactive contaminants from the atmosphere to vegetation, soil and aquatic systems. Fluvial redistribution of radiocaesium may contaminate downstream areas that were subject to low fallout and deliver significant quantities of highly contaminated fine sediment to the coastal zone. This study reports on the magnitude of fluvial transfer of Cs-134 and Cs-137 through river networks located across the fallout region. Initially six nested river monitoring stations were established within the Abukuma River basin from June 2011. Subsequently, an additional 23 stations were established between October 2012 and January 2013, which included stations within the Abukuma basin as well as smaller coastal catchments north and south of the power plant. Combined, these 29 sites represent a globally-unique river monitoring network designed to quantify sediment-associated transfer of radiocaesium from headwaters to the Pacific Coast of Japan. The catchments range in area from 8 to 5,172 km2 and span a large range in spatially-averaged radiocaesium inventories. Flow and turbidity (converted to suspended sediment concentration) were measured at each station while bulk suspended sediment samples were collected at regular intervals using time-integrated samplers to allow measurement of Cs-134 and Cs-137 activity concentrations by gamma spectrometry. Preliminary monitoring data showed highly elevated but also highly variable fluxes of radiocaesium in rivers across the fallout region. High magnitude flows in response to typhoon events exported large quantities of radiocaesium. Rivers are an important and continuing source of radiocaesium input to the coastal environment and the Pacific Ocean in

    The river hippopotamus (Hippopotamus amphibius), one of the closest extant relatives to cetaceans, is a large African even-toed ungulate (Artiodactyla) that grazes and has a semiaquatic lifestyle. Given its unusual phenotype, ecology, and evolutionary history, we sought to measure the topographic distribution of retinal ganglion cell density using stereology and retinal wholemounts. We estimated a total of 243,000 ganglion cells of which 3.4% (8,300) comprise alpha cells. The topographic distribution of both total and alpha cells reveal a dual topographic organization of a temporal and nasal area embedded within a well-defined horizontal streak. Using maximum density of total ganglion cells and eye size (35 mm, axial length), we estimated upper limits of spatial resolving power of 8 cycles/deg (temporal area, 1,800 cells/mm(2) ), 7.7 cycles/deg (nasal area, 1,700 cells/mm(2) ), and 4.2 cycles/deg (horizontal streak, 250 cells/mm(2) ). Enhanced resolution of the temporal area toward the frontal visual field may facilitate grazing, while resolution of the horizontal streak and nasal area may help the discrimination of objects (predators, conspecifics) in the lateral and posterior visual fields, respectively. Given the presumed role of alpha cells to detect brisk transient stimuli, their similar distribution to the total ganglion cell population may facilitate the detection of approaching objects in equivalent portions of the visual field. Our finding of a nasal area in the river hippopotamus retina supports the notion that this specialization may enhance visual sampling in the posterior visual field to compensate for limited neck mobility as suggested for rhinoceroses and cetaceans. © 2017 Wiley Periodicals, Inc.

    Markov's inequality for the derivative of algebraic polynomials is considered on C^2-smooth Jordan arcs. The asymptotically best estimate is given for the kth derivative for all k=1,2,\\dots . The best constant is related to the behaviour around the endpoints of the arc of the normal derivative of the Green's function of the complementary domain. The result is deduced from the asymptotically sharp Bernstein inequality for the kth derivative at inner points of a Jordan arc, which is derived from a recent result of Kalmykov and Nagy on the Bernstein inequality on analytic arcs. In the course of the proof we shall also need to reduce the analyticity condition in this last result to C^2-smoothness. Bibliography: 21 titles.

  17. Mapping spatial patterns of stream power and channel change along a gravel-bed river in northern Yellowstone

    NASA Astrophysics Data System (ADS)

    Lea, Devin M.

    Stream power represents the rate of energy expenditure along a river and can be calculated using topographic data acquired via remote sensing or field surveys. This study used remote sensing and GIS tools along with field data to quantitatively relate temporal changes in the form of Soda Butte Creek, a gravel-bed river in northeastern Yellowstone National Park, to stream power gradients along an 8 km reach. Aerial photographs from 1994-2012 and cross-section surveys were used to develop a locational probability map and morphologic sediment budget to assess lateral channel mobility and changes in net sediment flux. A drainage area-to-discharge relationship and digital elevation model (DEM) developed from light detection and ranging (LiDAR) data were used to obtain the discharge and slope values needed to calculate stream power. Local and lagged relationships between mean stream power gradient at median peak discharge and volumes of erosion, deposition, and net sediment flux were quantified via spatial cross-correlation analyses. Similarly, autocorrelations of locational probabilities and sediment fluxes were used to examine spatial patterns of sediment sources and sinks. Energy expended above critical stream power was calculated for each time period to relate the magnitude and duration of peak flows to the total volumetric change in each time increment. Results indicated a lack of strong correlation between stream power gradients and sediment response, highlighting the geomorphic complexity of Soda Butte Creek and the inability of relatively simple statistical approaches to link sub-budget cell-scale sediment dynamics to larger-scale driving forces such as stream power gradients. Improving the moderate spatial resolution techniques used in this study and acquiring very-high resolution data from recently developed methods in fluvial remote sensing could help improve understanding of the spatial organization of stream power, sediment transport, and channel change in

    The aim of this study was to describe the knowledge, attitudes, and practices toward colorectal cancer prevention and care in Jordan. A survey was designed to produce reliable estimates for the population's knowledge, attitudes, and practices in all 12 governorates of Jordan by using stratified random sampling. A representative sample of the adult population in Jordan completed a comprehensive tool which explored participants' knowledge about the risk factors associated with colorectal cancer, cancer prevention through lifestyle changes, and early cancer diagnosis and screening. According to the participants (n = 3196), colorectal cancer had the second highest percentage of screening recommendation (12.6%) after breast cancer (57.3%). Only 340 individuals (11%) reported ever screening for cancer. About 20% of the participants had heard of one of the screening tests for colorectal cancer. In fact, only 290 (9.1%) participants had performed the colorectal cancer screening tests. This study provides data that will help colorectal cancer prevention and treatment programs and may enhance the efficiency of colorectal cancer-controlling programs. The findings confirm the necessity of starting colorectal screening intervention that targets the most vulnerable individuals.

    This study aimed to identify the main risk factors of cerebrovascular accident (CVA) in Jordan. Identification of risk factors may help to reduce the incidence of CVA. A form was prepared for data collection which consisted of two parts to gather biodata and the incidence of risk factors. A sample of 200 patients with CVA (60% men) were randomly selected from various areas of Jordan. An age, region distribution, and gender-matched sample were selected to serve as control. Hypertension in the experimental group (66%) was significantly higher than the control group (32%) p  <  0.001. Half of the subjects with stroke had diabetes compared to 22% of the control group (p  <  0.001). Cardiovascular diseases were found in 29% of subjects with CVA compared to 14% in the control group (p  <  0.001). About 27% of the CVA group had hyperlipidemia in comparison to 13% in the controls (p <  0.002). Smokers represented 54% of the experimental group compared to 30% of the control group (p <  0.05). An important finding in the present study was that about half of the selected subjects with strokes were under the age of 60 years. In conclusion, hypertension, diabetes, cardiovascular diseases, hyperlipidemia, and smoking are risk factors for CVA in Jordan.

    his own personal ambition. Burning ambition—his own personal sense of political self-preservation—trumped Johnson's early beliefs about civil rights. Therefore because of his personal ambition he kept his opinions about civil rights silent while his operators utilized "out of sight, out of mind" policies towards race relations when necessary. While building this political community Johnson pledged electricity for votes. He had two goals: (1) create a market for LCRA-generated power to prevent private utilities from acquiring the power, and (2) create a political machine. Initially growth occurred slowly but Johnson used modern forms of communications and propaganda to construct a community; including radio, newsprint, theater, and public events and affairs. Johnson also laid the foundations for this community through the creation of shared community space and the promotion of a shared community-mindset. Johnson prioritized the creation of these community spaces over the construction of transmission lines and engaged in deceit when necessary—Arthur Stehling committed forgery—while pursuing Johnson's plans for the formation of this political machine through the conception of a new, common community. Johnson pushed for optimal growth and utilized every opportunity for publicity. These new structures signified the changes occurring across the landscape and for the first time the people of Central Texas began to feel the relief of the New Deal—five years after President Roosevelt initiated relief efforts. Subsequently, the people of Central Texas supported Johnson in his political endeavors. Secondly, this thesis explores the geographical expansion of multipurpose river development and rural electrification operations in Central Texas. Expansion was priority number one because this increased Johnson's political clout in Central Texas. Johnson expanded his control by infiltrating or manipulating newly forming rural electric cooperatives. His operators side

    Earlier onset of springtime weather, including earlier snowmelt, has been documented in the western United States over at least the last 50 years. Because the majority (is greater than 70%) of the water supply in the western U.S. comes from snowmelt, analysis of the declining spring snowpack (and shrinking glaciers) has important implications for the management of streamflow. The amount of water in a snowpack influences stream discharge which can also influence erosion and sediment transport by changing stream power, or the rate at which a stream can do work, such as move sediment and erode the stream bed. The focus of this work is the Wind River Range (WRR) in west-central Wyoming. Ten years of Moderate-Resolution Imaging Spectroradiometer (MODIS) snow-cover, cloud-gap-filled (CGF) map products and 30 years of discharge and meteorological station data are studied. Streamflow data from streams in WRR drainage basins show lower annual discharge and earlier snowmelt in the decade of the 2000s than in the previous three decades, though no trend of either lower streamflow or earlier snowmelt was observed within the decade of the 2000s. Results show a statistically-significant trend at the 95% confidence level (or higher) of increasing weekly maximum air temperature (for three out of the five meteorological stations studied) in the decade of the 1970s, and also for the 40-year study period as a whole. The extent of snow-cover (percent of basin covered) derived from the lowest elevation zone (2500-3000 m) of the WRR, using MODIS CGF snow-cover maps, is strongly correlated with maximum monthly discharge on 30 April, where Spearman's Rank correlation, rs,=0.89 for the decade of the 2000s. We also investigated stream power for Bull Lake Creek above Bull Lake; and found a trend (significant at the 90% confidence level) toward reduced stream power from 1970 to 2009. Observed changes in streamflow and stream power may be related to increasing weekly maximum air temperature

    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.

    In the present study, 19 microsatellite markers were assessed for their power of exclusion to test parentage in river buffalo. Microsatellite genotypes of 216 unrelated buffaloes belonging to five different breeds were utilized for the study. The probabilities of exclusion were calculated for three hypothetical situations viz. paternity testing (PE1), one parental genotype unavailable (PE2) and exclusion of both parents i.e. substituted offspring (PE3). The mean probability of exclusion across 19 investigated markers in buffalo was 0.578 (PE1), 0.405 (PE2) and 0.764 (PE3) respectively. The probability of exclusion for paternity (PE1) ranged between 0.297 and 0.814 across different markers. The exclusion probability for the cases one parent unavailable (PE2) and substituted offspring (PE3) varied from 0.143 to 0.688 and 0.465 to 0.946 respectively. Polymorphism information content and expected heterozygosity were found to have significantly high correlation with probability of exclusion of microsatellite markers. The cumulative PE1 of nine marker loci was estimated to be 0.9999 while in case of absence of one of the parental genotypes, a minimum of 11 markers were required to achieve a cumulative PE2 of 0.999. In conclusion, the present study proposes two multiplex sets with four and five markers respectively for routine parentage testing in buffalo and an additional set of four markers for doubtful cases of paternity.

    Due to Fukushima Daiichi Nuclear Power Plant accident, radioactive materials including Cs-134 and Cs-137 were widely distributed in surrounded area. The radiocesiums have been transported in river networks. This study showed the monitoring results of radiocesium concentration in river waters and suspended sediments in Abukuma river basin and smaller coastal river catchments. The monitoring started at 6 sites from June 2011. Subsequently, additional 24 monitoring sites were installed between October 2012 and January 2013. Flow and turbidity (for calculation of suspended sediment concentration) were measured at each site, while suspended sediments and river water were collected every one or half month to measure Cs-134 and Cs-137 activity concentrations by gamma spectrometry. Activity concentrations of Cs-134 and Cs- 137 on suspended sediments were generally decreasing at all sites. The decreasing rate changed lower at about one year later from the accident. Activity concentration in river waters also showed the same tendency although there are only few data within 1 year from the accident. Activity concentrations measured at the same day are proportional to the mean catchment inventory. Therefore, the activity concentration can be normalized by the mean catchment inventory. The normalized activity can be fitted to following double exponential function: [At] = 1.551 exp (-5.265t) + 0.069 exp (-0.266 t), where t [year] is the time from the accident. There is no time evolution of Kd between suspended sediments and river water. Instead, Kd was varied spatially. Although the reason of the spatial variation is not clear for now, geology of the catchment (i.e. mineral composition of suspended particles) seems to relate to the variation.

    Tenom Pangi Hydro Power Station in Tenom, Sabah is suffering from poor river quality with a lot of suspended trashes. This problem necessitates the need for a trash diverter to divert the trash away from the intake region. Previously, a trash diverter (called Trash Diverter I) was installed at the site but managed to survived for a short period of time due to an impact with huge log as a results of a heavy flood. In the current project, a second trash diverter structure is designed (called Trash Diverter II) with improved features compared to Trash Diverter I. The Computational Fluid Dynamics (CFD) analysis is done to evaluate the river flow interaction onto the trash diverter from the fluid flow point of view, Computational Fluids Dynamics is a numerical approach to solve fluid flow profile for different inlet conditions. In this work, the river geometry is modeled using commercial CFD code, FLUENT®. The computational model consists of Reynolds Averaged Navier-Stokes (RANS) equations coupled with other related models using the properties of the fluids under investigation. The model is validated with site-measurements done at Tenom Pangi Hydro Power Station. Different operating condition of river flow rate and weir opening is also considered. The optimum angle is determined in this simulation to further use the data for 3D simulation and structural analysis.

    The possibility to achieved a high integration of climate related energies (i.e. run-of-river-, wind- and solar- energies) depends on the possibility to balance the potentially large deviations between the related intermittent productions and the variable demand using storage facilities such as water storage in accumulation dams. These deviations depend obviously on how energy sources co-fluctuate in time among themselves and with the demand as well. Balancing hydropower system design as well as their operational planning requires the estimation of these co-fluctuations, resulting from both, space and time weather structures/patterns and watershed features (e.g. area, altitude range, geological basement …). The co-fluctuations between intermittent energy sources can be estimated from observed time series when available or from time series obtained from simulation models when not or when different contexts have to be considered (e.g. climate change and/or intermittent energy development). The simulation models were classically developed and evaluated for the prediction of each energy source individually. The ability of the models to simulate relevant levels of co-fluctuations is however to our knowledge not really considered. This issue is however critical and should also require thorough attention. This work focuses on run-of-river and solar- power interaction assessment. The study area is located in Italy where run-of-river power plants, mainly located on small river tributaries, represent almost 43 % of the hydropower production with only 27 % of the installed hydro-capacity (in 2011). Solar power generation is available from observed time series at different locations over the region but there is no systematic measurement of water discharges over the considered river tributaries and discharges have to be reconstituted from simulations. The absence of discharge measures makes also impossible to calibrate hydrological model at each power plant location. We thus

    The relationship of the El-Nino/Southern Oscillation (ENSO) to hydrology is typically discussed in terms of the ability to separate significantly different hydrologic variable responses versus the anomaly that has taken place. Most of the work relating ENSO trends to proxy variables had been done on precipitation records until the mid 1990s, at which point increasing numbers of studies started to focus on ENSO relationships with streamflow as well as other environmental variables. The signals in streamflow are typically complex, representing the integration of both climatic, landscape, and anthropological responses that are able to strengthen the inherent ENSO signal in chaotic regional precipitation data. There is a need to identify climate non-stationarities related to ENSO and their links to watershed-scale outcomes. For risk-management in particular, inter-annual modes of climate variability and their seasonal expression are of interest. In this study, we analyze 36 years of historical monthly streamflow data from the Little River Watershed (LWR), a coastal plain ecosystem in Georgia, in conjunction with wavelet spectral analysis and modeling via the Soil & Water Assessment Tool (SWAT). Using both spectral and physical models allows us to identify the mechanism by which the ENSO signal power in surface and simulated groundwater flow is strengthened as compared to precipitation. The clear increase in the power of the inter-annual climate signal is demonstrated by shared patterns in water budget and exceedance curves, as well as in high ENSO related energy in the 95% significant wavelet spectra for each variable and the NINO 3.4 index. In the LRW, the power of the ENSO teleconnection is increased in both the observed and simulated stream flow through the mechanisms of groundwater flow and interflow, through confinement by a geological layer, the Hawthorn Formation. This non-intuitive relationship between ENSO signal strength and streamflow could prove to be

    River flows withdrawals to supply small run-of-river hydropower plants have been increasing significantly in recent years - particularly in the Alpine area - as a consequence of public incentives aimed at enhancing energy production from renewable sources. This growth further raised the anthropic pressure in areas traditionally characterized by an intense exploitation of water resources, thereby triggering social conflicts among local communities, hydropower investors and public authorities. This brought to the attention of scientists and population the urgency for novel and quantitative tools for assessing the hydrologic impact of these type of plants, and trading between economic interests and ecologic concerns. In this contribution we propose an analytical framework that allows for the estimate of the streamflow availability for hydropower production and the selection of the run-of-river plant capacity, as well as the assessment of the related profitability and environmental impacts. The method highlights the key role of the streamflow variability in the design process, by showing the significance control of the coefficient of variation of daily flows on the duration of the optimal capacity of small run-of-river plants. Moreover, the analysis evidences a gap between energy and economic optimizations, which may result in the under-exploitation of the available hydropower potential at large scales. The disturbances to the natural flow regime produced between the intake and the outflow of run-of-river power plants are also estimated within the proposed framework. The altered hydrologic regime, described through the probability distribution and the correlation function of streamflows, is analytically expressed as a function of the natural regime for different management strategies. The deviations from pristine conditions of a set of hydrologic statistics are used, jointly with an economic index, to compare environmental and economic outcomes of alternative plant

    West Fork Carson River offers the best opportunity for power development in the Carson River basin. The Hope Valley reservoir site could be developed to provide adequate storage regulation and concentration of fall would permit utilization of 1,400 feet of head in 51h miles below the clam site, or 1,900 feet of head in about 972 miles below the dam site; however, the average annual runoff susceptible of development is only about 70,000 acre-feet which limits the power that could be developed continuously in an average year with regulation to about 8,700 kilowatts utilizing 1,400 feet of head, or 12,000 kilowatts utilizing 1,900 feet of head. The method and degree of development will be determined to large extent by the method devised to supplement regulated flows from the Hope Valley reservoir to supply the water already appropriated for irrigation. If the Hope Valley site and the Watasheamu site on East Fork Carson River were developed coordinately water could be transferred to the West Fork for distribution through canals leading from that stream thus satisfying the deficiency due to regulation at Hope Valley and release of stored water on a power schedule. This would permit utilization of the entire 1,900 feet of fall. Independent development of the West Fork for optimum power production would require re-regulation of releases from Hope Valley reservoir and storage of a considerable part of the fall and winter flow for use during the irrigation season. Adequate storage capacity is apparently not available on the West Fork below Hope Valley; but offstream storage may be available in Diamond Valley which could be utilized by diversion from the West Fork near Woodfords. This would limit the utilization of the stream for power purposes to the development of the 1,400 feet of head between the Hope Valley dam site and Wood fords. In a year of average discharge East Fork Carson River and three of its principal tributaries could be developed to produce about 13

  9. Electrical power from sea and river water by reverse electrodialysis: a first step from the laboratory to a real power plant.

    Electricity can be produced directly with reverse electrodialysis (RED) from the reversible mixing of two solutions of different salinity, for example, sea and river water. The literature published so far on RED was based on experiments with relatively small stacks with cell dimensions less than 10 × 10 cm(2). For the implementation of the RED technique, it is necessary to know the challenges associated with a larger system. In the present study we show the performance of a scaled-up RED stack, equipped with 50 cells, each measuring 25 × 75 cm(2). A single cell consists of an AEM (anion exchange membrane) and a CEM (cation exchange membrane) and therefore, the total active membrane area in the stack is 18.75 m(2). This is the largest dimension of a reverse electrodialysis stack published so far. By comparing the performance of this stack with a small stack (10 × 10 cm(2), 50 cells) it was found that the key performance parameter to maximal power density is the hydrodynamic design of the stack. The power densities of the different stacks depend on the residence time of the fluids in the stack. For the large stack this was negatively affected by the increased hydrodynamic losses due to the longer flow path. It was also found that the large stack generated more power when the sea and river water were flowing in co-current operation. Co-current flow has other advantages, the local pressure differences between sea and river water compartments are low, hence preventing leakage around the internal manifolds and through pinholes in the membranes. Low pressure differences also enable the use of very thin membranes (with low electrical resistance) as well as very open spacers (with low hydrodynamic losses) in the future. Moreover, we showed that the use of segmented electrodes increase the power output by 11%.

    Due to the Fukushima Daiichi Nuclear Power Plant accident triggered by the earthquake and subsequent tsunami on 11 March 2011, many radionuclides were released into environments such as forests, rivers, dam reservoirs, and the ocean. 137Cs is one of the most important radio-contaminants. In order to investigate 137Cs transport and discharge from contaminated basins, in this study we developed a three dimensional model of five river basins near to the Fukushima Daiichi Nuclear Power Plant. We applied the General-purpose Terrestrial fluid-Flow Simulator (GETFLOWS) watershed code to the Odaka, Ukedo, Maeda, Kuma, and Tomioka River basins. The main land uses in these areas are forests, rice paddy fields, crop fields and urban. The Ukedo, Kuma and Tomioka Rivers have relatively large dam reservoirs (>106 m3) in the upper basins. The radiocesium distribution was initiated based on the Second Airborne Monitoring Survey. The simulation periods were 2011 Typhoon Roke, nine heavy rainfall events in 2013, Typhoons Man-yi and Wipha, and tropical storm Etau in 2015. Water, sediment, and radiocesium discharge from the basins was calculated for these events. The characteristics of 137Cs runoff between the different basins were evaluated in terms of land use, the effect of dam reservoirs, geology, and the fraction of the initial radiocesium inventory discharged. The absolute 137Cs discharge from the Ukedo River basin was highest, however the 137Cs discharge ratio was lowest due to the Ogaki Dam and the inventory being mainly concentrated in upstream forests. The results for the water, suspended sediment and radiocesium discharge as a function of total precipitation over the various rainfall events can be used to predict discharges for other typhoons.

    Thermoelectric power plants require large volumes of water for cooling, which can introduce drought vulnerability and compete with other water needs. Alternative cooling technologies, such as cooling towers and hybrid wet-dry or dry cooling, present opportunities to reduce water diversions. This case study uses a custom, geographically resolved river basin-based model for eleven river basins in the state of Texas (the Brazos and San Jacinto-Brazos, Colorado and Colorado-Brazos, Cypress, Neches, Nueces, Red, Sabine, San Jacinto, and Trinity River basins), focusing on the Brazos River basin, to analyze water availability during drought. We utilized two existing water availability models for our analysis: (1) the full execution of water rights—a scenario where each water rights holder diverts the full permitted volume with zero return flow, and (2) current conditions—a scenario reflecting actual diversions with associated return flows. Our model results show that switching the cooling technologies at power plants in the eleven analyzed river basins to less water-intensive alternative designs can potentially reduce annual water diversions by 247-703 million m3—enough water for 1.3-3.6 million people annually. We consider these results in a geographic context using geographic information system tools and then analyze volume reliability, which is a policymaker's metric that indicates the percentage of total demand actually supplied over a given period. This geographic and volume reliability analysis serves as a measure of drought susceptibility in response to changes in thermoelectric cooling technologies. While these water diversion savings do not alleviate all reliability concerns, the additional streamflow from the use of dry cooling alleviates drought concerns for some municipal water rights holders and might also be sufficient to uphold instream flow requirements for important bays and estuaries on the Texas Gulf coast.

  14. 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.

  16. Mapping Spatial Distributions of Stream Power and Channel Change along a Gravel-Bed River in Northern Yellowstone

    Lea, D. M.; Legleiter, C. J.

    2014-12-01

    Stream power represents the rate of energy expenditure along a river and can be calculated using topographic data acquired via remote sensing. This study used remotely sensed data and field measurements to quantitatively relate temporal changes in the form of Soda Butte Creek, a gravel-bed river in northeastern Yellowstone National Park, to stream power gradients along an 8 km reach. Aerial photographs from 1994-2012 and cross-section surveys were used to assess lateral channel mobility and develop a morphologic sediment budget for quantifying net sediment flux for a series of budget cells. A drainage area-to-discharge relationship and digital elevation model (DEM) developed from LiDAR data were used to obtain the discharge and slope values, respectively, needed to calculate stream power. Local and lagged relationships between mean stream power gradient at median peak discharge and volumes of erosion, deposition, and net sediment flux were quantified via spatial cross-correlation analyses. Similarly, autocorrelations of locational probabilities and sediment fluxes were used to examine spatial patterns of channel mobility and sediment transfer. Energy expended above critical stream power was calculated for each time period to relate the magnitude and duration of peak flows to the total volume of sediment eroded or deposited during each time increment. Our results indicated a lack of strong correlation between stream power gradients and sediment flux, which we attributed to the geomorphic complexity of the Soda Butte Creek watershed and the inability of our relatively simple statistical approach to link sediment dynamics expressed at a sub-budget cell scale to larger-scale driving forces such as stream power gradients. Future studies should compare the moderate spatial resolution techniques used in this study to very-high resolution data acquired from new fluvial remote sensing technologies to better understand the amount of error associated with stream power

    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.

    Scorpionism is an endemic public health problem in Jordan encountered by health providers in all parts of the country. This study updates epidemiological data on scorpion sting encounters in Jordan. Data on scorpion sting encounters were obtained from government and military hospitals around the country, and the National Drug and Poison Information Center (NDPIC). P values and 95% confidence intervals (CIs) were calculated using SPSS Professional Statistics Package version 22 (IBM Corp., Armonk, NY) program. Epidemiological data on 1205 scorpion sting cases reported between 2006 and 2012 are reported. Male to female ratio was 1.18:1, aged 23.3±16 (mean±SD) and 26.4±16.9 years for males and females, respectively. Age groups between 1 to 20 years old constituted 44.6% of the total sting encounters, while adults aged >30 years constituted 30%. Scorpion sting encounters peaked in July (22.5%) and August (23%), with the lowest numbers of recorded cases in February and January (1.6 and 1.9%, respectively). Scorpion stings occurred mostly outdoors (66%). Medical complications associated with scorpion sting cases included fever, difficulty in breathing, drowsiness and dizziness, and numbness, while severe complications include respiratory failure and tachycardia. Hospitalization required 1 to 3 days among admitted patients with no fatalities. Scorpion stings remain a medical problem in Jordan that requires more attention by health providers. Reporting of scorpion sting cases should be enforced from all healthcare centers throughout the country to better understand the epidemiology and health implications of human encounters.

    To evaluate contact lens prescribing trends among optometrists in Jordan. Optometrists from 173 practices in Jordan were surveyed about prescribing contact lenses in their practice. Practitioners were required to record information for the last 10 patients that visited their practice. Demographic data such as age and gender was obtained for each patient. In addition, data relating to lens type, lens design, replacement methods and the care regime advised to each patient were recorded. Practitioners were required to provide information relating to their education and years of experience. The influence of education and experience with respect to lens prescribing trends was explored using linear regression models for the proportions of lens types fitted for patients. A total of 1730 contact lens fits were analyzed. The mean (±SD) age of lens wearers was 26.6 (±7.9) years, of whom 65% were female. Conventional hydrogel lenses were the most prescribed lenses, accounting for 60.3% of the fits, followed by silicone hydrogel lenses (31.3%), and rigid lenses (8.4%). In terms of lens design, spherical lenses appeared to be most commonly prescribed on monthly basis. Daily disposable lenses were second most prescribed lens modality, accounting for 20.4% of the study sample. Multi-purpose solution (MPS) was the preferred care regimen, with a prevalence of 88.1% reported in the study sample, compared to hydrogen peroxide (1-step and 2-step), which represented only 2.8% of the patients in this study. A relationship was established between the two educational groups for rigid lens prescribing (F=17.4, p<0.0001), while the experience of the optometrist was not a significant factor (F=0.4, p=0.54). This work has provides an up-to-date analysis of contact lens prescribing trends among optometrists in Jordan. Contact lens prescribing in terms of lens type, lens design, modality of wear and care regimen agree with global market trends with small variations. This report will help

    As with all large rivers in the United States, the Missouri River has been altered, with approximately 32.5 percent of the main stem length impounded and 32.5 percent channelized. These physical alterations to the environment have had effects on the fisheries, but studies examining the effects of alterations have been localized and for short periods of time. In response to the U.S. Fish and Wildlife Service biological opinion, the U.S. Army Corps of Engineers initiated monitoring of the fish community of the Missouri River in 2003. The goal of the Pallid Sturgeon Population Assessment Program is to provide information to detect changes in populations and habitat preferences with time for pallid sturgeon (Scaphirhynchus albus) and native target species in the Missouri River Basin. To determine statistical power of the Pallid Sturgeon Population Assessment Program, a power analysis was conducted using a normal linear mixed model with variance component estimates based on the first 3 years of data (2003 to 2005). In cases where 3 years of data were unavailable, estimates were obtained using those data. It was determined that at least 20 years of data, sampling 12 bends with 8 subsamples per bend, would be required to detect a 5 percent annual decline in most of the target fish populations. Power varied between Zones. Zone 1 (upstream from Lake Sakakawea) did not have any species/gear type combinations with adequate power, whereas Zone 3 (downstream from Gavins Point Dam) had 19 species/gear type combinations with adequate power. With a slight increase in the sampling effort to 12 subsamples per bend, the Pallid Sturgeon Population Assessment Program has adequate power to detect declines in shovelnose sturgeon (S. platorynchus) throughout the entire Missouri River because of large catch rates. The lowest level of non-occurrence (in other words, zero catches) at the bend level for pallid sturgeon was 0.58 using otter trawls in Zone 1. Consequently, the power of the

    River-channel topographic surveys were conducted and bed-material samples were collected along transects across the Platte River during water year 2001 (October 1, 2000 to September 30, 2001). A total of 57 transect lines or cross sections were established within three study reaches located along the middle channel of the Platte River in a 2,650-acre parcel of land owned by the Nebraska Public Power District (NPPD), hereinafter referred to as the Cottonwood Ranch Property. Five additional cross sections were established downstream of the Cottonwood Ranch Property across the entire width of the Platte River as a component of a proposed future general monitoring program. A development and enhancement plan is proposed by NPPD on the Cottonwood Ranch Property to satisfy their Federal Energy Regulatory Commission (FERC) relicensing guidelines. The goal of the plan is to improve habitat along this reach for endangered species. The United States Geological Survey (USGS) designed a monitoring and research program to study and detect what effects, if any, these channel management actions have on channel morphology and sediment transport within and adjacent to the Cottonwood Ranch Property. This report presents the data-collection methods and summarizes the geomorphic data collected in support of the monitoring program for water year 2001.

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

    2013-04-01

    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

    1984-01-01

    Failure of the debris dam, blocking the outflow of Spirit Lake near Mount St. Helens, could result in a mudflow down the Toutle and Cowlitz Rivers into the Columbia River. Flood elevations at the Trojan Nuclear Power Plant on the Columbia River, 5 mi upstream from the Cowlitz River, were simulated with a hydraulic routing model. The simulations are made for four Columbia River discharges in each of two scenarios, one in which Columbia River floods coincide with a mudflow and the other in which Columbia River floods follow a mudflow sediment deposit upstream from the Cowlitz River. In the first scenario, Manning 's roughness coefficients for clear water and for mudflow in the Columbia River are used; in the second scenario only clear water coefficients are used. The grade elevation at the power plant is 45 ft above sea level. The simulated elevations exceed 44 ft if the mudflow coincides with a Columbia River discharge that has a recurrence interval greater than 10 years (610,000 cu ft/sec); the mudflow is assumed to extend downstream from the Cowlitz River to the mouth of the Columbia River, and Manning 's roughness coefficients for a mudflow are used. The simulated elevation is 32 ft if the mudflow coincides with a 100-yr flood (820,000 cu ft/sec) and clear-water Manning 's coefficients are used throughout the entire reach of the Columbia River. The elevations exceed 45 ft if a flow exceeding the 2-yr peak discharge in the Columbia River (410,000 cu ft/sec) follows the deposit of 0.5 billion cu yd of mudflow sediment upstream of the Cowlitz River before there has been any appreciable scour or dredging of the deposit. In this simulation it is assumed that: (1) the top of the sediment deposited in the Columbia River is at an elevation of 30 ft at the mouth of the Cowlitz River, (2) the surface elevation of the sediment deposit decreases in an upstream direction at a rate of 2.5 ft/mi, and (3) clear water Manning 's coefficients apply to the entire modeled reach of

    Domestic violence is a forced pattern of behavior that happened in domestic settings to gain or maintain power and control over an individual. The aim of this work is to study the magnitude of domestic violence in south region of Jordan. The retrospective study was retrieved from the medico-legal reports of domestic violence cases referred to the Directorate of Forensic Medicine in south region of Jordan during six years period starting from 1st of January 2010 till the end of December 2015. The total number of cases was 128. The majority was females (77.3%), high prevalence (41.4%) was found in adult age group (18 years and above) in both genders. The prevalence was higher in rural areas (75%). Sexual abuse was the commonest method of domestic violence in both genders (41.4%). Nearly a quarter of cases (23.4%) leaving home as an outcome. Spring months represented the highest percentage of domestic violence occurrence (28.1%). Family and financial problems were reported in 71.1% of cases. Domestic violence rate in South Jordan is much lower than in other areas but still considered a problem and should be given high priority with regard to prevention, investigation and treatment.

    The bacterium Simkania negevensis is a germ associated with respiratory diseases. This study aims at estimating the prevalence of Simkania in the Jordanian population. Serum samples from 664 Jordanian males and females, aged 2 to 86 years were collected. IgG and IgM Simkania-specific antibodies were detected using an indirect immunofluorescence test. Seropositivity titers for IgG and IgM were defined as 1:8 and 1:10, respectively. The overall prevalence of IgG antibody in all examined Jordanian nationals was 58.4%. IgG seropositivity was low in children under the age of 10 years (34.2%), and increased rapidly with age and ranged between 49.4% and 72%. Simkania-specific IgM was detected in 24.8% of subjects. IgM prevalence in children under 10 years was lowest (10.5%) and increased in older ages and remained above 20%. Overall detection rates of both IgG and IgM were significantly higher in females than males (60.7% vs. 54.5% for IgG and 26.7% vs. 21.7% for IgM). These data indicate that Simkania infection is highly prevalent in Jordan. The high level of seropositivity is most likely maintained by re-infections or chronic infections. Our data may serve as a basis to elucidate the pathogenesis of Simkania in Jordan. PMID:25763051

    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.

  10. Jordan cells of periodic loop models

    Jordan cells in transfer matrices of finite lattice models are a signature of the logarithmic character of the conformal field theories that appear in their thermodynamical limit. The transfer matrix of periodic loop models, TN, is an element of the periodic Temperley-Lieb algebra {E}PTL_N(\\beta , \\alpha ), where N is the number of sites on a section of the cylinder, and β = -q - q-1 = 2cos λ and α the weights of contractible and non-contractible loops. The thermodynamic limit of TN is believed to describe a conformal field theory of central charge c = 1 - 6λ2/(π(λ - π)). The abstract element TN acts naturally on (a sum of) spaces \\tilde{V}_N^d, similar to those upon which the standard modules of the (classical) Temperley-Lieb algebra act. These spaces known as sectors are labeled by the numbers of defects d and depend on a twist parameter v that keeps track of the winding of defects around the cylinder. Criteria are given for non-trivial Jordan cells of TN both between sectors with distinct defect numbers and within a given sector.

    This paper examines factors influencing a patient's choice of provider for outpatient health care services in Jordan. Factors including demographic, socioeconomic, insurance status, quality of care, household size and cost of health care were studied using a multinomial logit model applied to a sample of 1031 outpatients from the Jordan heathcare utilization and expenditure survey, 2000. The patient's socioeconomic and demographic characteristics affected provider choice. Insurance was not statistically significant in choosing Ministry of Health facilities over other providers. Patients utilizing the public sector were price sensitive, and therefore any attempt to improve accessibility to health care services in Jordan should take this into consideration.

  12. The Angular Momentum Dilemma and Born-Jordan Quantization

    2017-01-01

    The rigorous equivalence of the Schrödinger and Heisenberg pictures requires that one uses Born-Jordan quantization in place of Weyl quantization. We confirm this by showing that the much discussed " angular momentum dilemma" disappears if one uses Born-Jordan quantization. We argue that the latter is the only physically correct quantization procedure. We also briefly discuss a possible redefinition of phase space quantum mechanics, where the usual Wigner distribution has to be replaced with a new quasi-distribution associated with Born-Jordan quantization, and which has proven to be successful in time-frequency analysis.

    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.

  14. Run-of-river power plants in Alpine regions: Whither optimal capacity?

    NASA Astrophysics Data System (ADS)

    Lazzaro, G.; Botter, G.

    2015-07-01

    Although run-of-river hydropower represents a key source of renewable energy, it cannot prevent stresses on river ecosystems and human well-being. This is especially true in Alpine regions, where the outflow of a plant is placed several kilometers downstream of the intake, inducing the depletion of river reaches of considerable length. Here multiobjective optimization is used in the design of the capacity of run-of-river plants to identify optimal trade-offs between two contrasting objectives: the maximization of the profitability and the minimization of the hydrologic disturbance between the intake and the outflow. The latter is evaluated considering different flow metrics: mean discharge, temporal autocorrelation, and streamflow variability. Efficient and Pareto-optimal plant sizes are devised for two representative case studies belonging to the Piave river (Italy). Our results show that the optimal design capacity is strongly affected by the flow regime at the plant intake. In persistent regimes with a reduced flow variability, the optimal trade-off between economic exploitation and hydrologic disturbance is obtained for a narrow range of capacities sensibly smaller than the economic optimum. In erratic regimes featured by an enhanced flow variability, instead, the Pareto front is discontinuous and multiple trade-offs can be identified, which imply either smaller or larger plants compared to the economic optimum. In particular, large capacities reduce the impact of the plant on the streamflow variability at seasonal and interannual time scale. Multiobjective analysis could provide a clue for the development of policy actions based on the evaluation of the environmental footprint of run-of-river plants.

    Following the initial fall out from Fukushima Dai-ichi Nuclear Power Plant (FDNPP), a significant amount of radiocesium has been discharged from Abukuma River into the Pacific Ocean. This study attempted to numerically simulate the flux of radiocesium into Abukuma River by developing the multiple compartment model which incorporate the transport process of the radionuclide from the ground surface of the catchment area into the river, a process called wash off. The results from the model show that the sub-basins with a high percentage of forest area release the radionuclides at lower rate compared to the other sub-basins. In addition the results show that the model could predict the seasonal pattern of the observed data. Despite the overestimation observed between the modeled data and the observed data, the values of R(2) obtained from (137)Cs and (134)Cs of 0.98 and 0.97 respectively demonstrate the accuracy of the model. Prediction of the discharge from the basin area for 100 years after the accident shows that, the flux of radiocesium into the Pacific Ocean is still relatively high with an order of magnitude of 10(9) bq.month(-1) while the total accumulation of the discharge is 111 TBq for (137)Cs and 44 TBq for (134)Cs.

    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.

    2014-09-01

    It is by now well known that three qubits can be totally entangled in two physically distinct ways. Here we review work classifying the physically distinct forms of 3-qubit entanglement using the elegant framework of Jordan algebras, Freudenthal-Kantor triple systems and groups of type E7. In particular, it is shown that the four Freudenthal-Kantor ranks correspond precisely to the four 3-qubit entanglement classes: (1) Totally separable A-B-C, (2) Biseparable A-BC, B-CA, C-AB, (3) Totally entangled W, (4) Totally entangled GHZ. The rank 4 GHZ class is regarded as maximally entangled in the sense that it has non-vanishing quartic norm, the defining invariant of the Freudenthal-Kantor triple system. While this framework is specific to three qubits, we show here how the essential features may be naturally generalised to an arbitrary number of qubits.

    The Platte River Power Authority (Platte River) is a political subdivision of the state of Colorado, owned by the four municipalities of Fort Collins, Loveland, Longmont and Estes Park, Colorado. Platte River is a non-profit, publicly owned, joint-action agency formed to construct, operate and maintain generating plants, transmission systems and related facilities for the purpose of delivering to the four municipalities electric energy for distribution and resale. Platte River, as a participant in the US Department of Energy (DOE) Site Operator Program, worked to accomplish the Site Operator Program goals and objectives to field test and evaluate electric and electric-hybrid vehicles and electric vehicle systems in a real world application/environment. This report presents results of Platte River`s program (Program) during the five-years Platte River participated in the DOE Site Operator Program. Platte River participated in DOE Site Operator Program from July 3, 1991 through August 31, 1996. During its Program, Platte River conducted vehicle tests and evaluations, and electric vehicle demonstrations in the Front Range region of Northern Colorado. Platte River also investigated electric vehicle infrastructure issues and tested infrastructure components. Platte River`s Program objectives were as follows: evaluate the year round performance, operational costs, reliability, and life cycle costs of electric vehicles in the Front Range region of Northern Colorado; evaluate an electric vehicle`s usability and acceptability as a pool vehicle; test any design improvements or technological improvements on a component level that may be made available to PRPA and which can be retrofit into vehicles; and develop, test and evaluate, and demonstrate components to be used in charging electric vehicles.

  4. Quality assurance guides health reform in Jordan.

    Abubaker, W; Abdulrahman, M

    1996-01-01

    In November 1995, a World Bank mission went to Jordan to conduct a study of the health sector. The study recommended three strategies to reform the health sector: decentralization of Ministry of Health (MOH) management; improvement of clinical practices, quality of care, and consumer satisfaction; and adoption of treatment protocols and standards. The MOH chose quality assurance (QA) methods and quality management (QM) techniques to accomplish these reforms. The Monitoring and QA Directorate oversees QA applications within MOH. It also institutes and develops the capacity of local QA units in the 12 governorates. The QA units implement and monitor day-to-day QA activities. The QM approach encompasses quality principles: establish objectives; use a systematic approach; teach lessons learned and applicable research; use QA training to teach quality care, quality improvement, and patient satisfaction; educate health personnel about QM approaches; use assessment tools and interviews; measure the needs and expectations of local health providers and patients; ensure feedback on QA improvement projects; ensure valid and reliable data; monitor quality improvement efforts; standardize systemic data collection and outcomes; and establish and disseminate QA standards and performance improvement efforts. The Jordan QA Project has helped with the successful institutionalization of a QA system at both the central and local levels. The bylaws of the QA councils and committees require team participation in the decision-making process. Over the last two years, the M&QA Project has adopted 21 standards for nursing, maternal and child health care centers, pharmacies, and medications. The Balqa pilot project has developed 44 such protocols. Quality improvement (COUGH) studies have examined hyper-allergy, analysis of patient flow rate, redistribution of nurses, vaccine waste, and anemic pregnant women. There are a considerable number of on-going clinical and non-clinical COUGH studies

    Background Difficulties swallowing oral medications can affect patient compliance and consequently can compromise patient health. Objective To investigate the prevalence of difficulties in swallowing oral medications among a sample of the Jordanian population and the techniques used to overcome such difficulties. Setting The study was carried out in outpatient pharmacies in the north of Jordan. Method Adult patients who were taking at least one solid oral dosage form for at least 1 month were interviewed using a questionnaire. The questionnaire included demographic details, current medication use, questions about swallowing difficulties, and patient strategies to overcome such difficulties. Main outcome measure The study measured the number of patients reporting difficulties in swallowing oral medications and the techniques used to overcome swallowing difficulties. Results In this study 1250 patients were interviewed and 130 patients reported that they experienced or were currently experiencing difficulties in swallowing oral medications (10.4%). In order to overcome swallowing difficulties, 112 patients (86.2%) stated that they drink more water while 22 patients (16.9%) stated that they cut or crush their solid dosage forms, and 13 patients stated that they open their capsules. Forty-five patients (34.6%) stated that they sometimes skip their doses due to swallowing difficulties. The majority of participants with swallowing difficulties did not discuss their difficulties with their physicians or pharmacists (85.4%). Conclusion Difficulties in swallowing oral medications is a problem that is encountered in Jordan. Techniques used to overcome swallowing difficulties such as crushing or opening capsules can compromise medication efficacy and negatively impact patient health outcomes. Non-compliance due to swallowing difficulties raises a major concern.

    To provide an overview of nursing research in Jordan based on the topic researched, source and setting of data collection, methodology, theoretical framework used and source of funding. Nursing research contributes to nursing education, clinical practice, health policy and the establishment of nursing research priorities in Jordan to guide future research. Databases such as MEDLINE, CINAHL, Google Scholar, PubMed and national sources were searched for published articles related to nursing in Jordan through a range of keywords. Articles were included in the analysis if they were published in English or Arabic through December 2012. The search resulted in the identification of 999 publications, from which 462 articles met the inclusion criteria and were included in the review. The highest percentage of studies (23% of articles) focused on nursing management issues. Forty-four per cent were conducted in a hospital setting; only six studies used a nursing theory. Seventy-seven per cent of the studies were quantitative and 29.0% were funded mostly by universities. Twenty-one per cent were not directly related to improving nursing education or practice in Jordan. A Jordanian Database for nursing research was developed as a result of this review. Jordanian nurses have slowly started to build nursing research, the real nursing research work in Jordan started with the return of the first PhD graduate to Jordan in 1986. Jordanian nurses in collaboration with international colleagues were motivated to publish research and build the body of nursing knowledge. © 2013 International Council of Nurses.

    We investigate scenarios of hydroelectric power generation for an Alpine run-of-the-river plant in 2050. To this end, we include a conversion from streamflow to energy in a hydrological model of the basin, and we introduce a set of benchmark climate scenarios to evaluate expected future production. These are a "future-like-present" scenario assuming future precipitation and temperature inputs to be statistically equivalent to those observed during the recent past at the same location, a "warmer-future" scenario, which considers an additional increase in temperature, and a "liquid-only" scenario where only liquid precipitation is admitted. In addition, two IPCC-like climatic scenarios (RCP 4.5 and RCP 8.5) are considered. Uncertainty in glaciers' volume is accounted by initializing the hydrological model with two different inventories of glaciers. Ensemble results reveal that 1) an average decrease between -40% and -19% of hydroelectric power generation in 2050 is predicted at the plant considered (with respect to present condition); 2) an average decrease between -20% and -38% of cumulative incoming streamflow volume at the plant is also predicted, again with respect to present condition; 3) these effects are associated with a strong average decrease of the volume of glaciers (between -76% and -96%, depending on the initial value considered). However, Monte Carlo simulations show that results are also prone to high uncertainties. Implications of these results for run-of-the-river plants are discussed.

  8. Tidal hydrodynamics and erosional power in the Fly River delta, Papua New Guinea

    A two-dimensional numerical model is used to study tidal hydrodynamics and distribution of bed shear stresses in the Fly River delta, Papua New Guinea. The model describes the propagation of the tidal wave within the delta and along the river. Model results indicate that tidal discharge at the mouths of the distributary channels is between 10 and 30 times larger than the river discharge, and that the upstream part of the delta is flood-dominated, whereas near the mouth, the delta is ebb-dominated. Numerical simulations allow us to investigate the sensitivity of fluxes and bottom stresses with respect to the variations of sea level and the area of delta islands. The results suggest that a decrease in the total area of the delta occupied by islands increases the tidal prism and, therefore, the bed shear stresses. Similarly, an increase in sea level reduces the dissipation of the tidal signal and speeds up the propagation of the tidal wave within the delta, thus yielding higher discharges and increased bed shear stresses.

    This study involved measurement of concentrations of dissolved and particulate radiocesium ((134)Cs and (137)Cs) in river water, and determination of the quantitative relations between the amount of deposited (137)Cs and (137)Cs concentrations in river waters after the Fukushima Daiichi nuclear power plant accident. First, the current concentrations of dissolved and particulate (134)Cs·(137)Cs were determined in a river watershed from 20 sampling locations in four contaminated rivers (Abukuma, Kuchibuto, Shakado, and Ota). Distribution characteristics of different (137)Cs forms varied with rivers. Moreover, a higher dissolved (137)Cs concentration was observed at the sampling location where the (137)Cs deposition occurred much more heavily. In contrast, particulate (137)Cs concentration along the river was quite irregular, because fluctuations in suspended solids concentrations occur easily from disturbance and heavy precipitation. A similar tendency with dissolved (137)Cs distribution was observed for the (137)Cs concentration per unit weight of suspended solids. Regression analysis between deposited (137)Cs and dissolved/particulate (137)Cs concentrations was performed for the four rivers. The results showed a strong correlation between deposited (137)Cs and dissolved (137)Cs, and a relatively weak correlation between deposited (137)Cs and particulate (137)Cs concentration for each river. However, if the particulate (137)Cs concentration was converted to (137)Cs concentration per unit weight of suspended solid, the values showed a strong correlation with deposited (137)Cs.

  12. Increasing drought in Jordan: Climate change and cascading Syrian land-use impacts on reducing transboundary flow.

    2017-08-01

    In countries where severe drought is an anticipated effect of climate change and in those that heavily depend on upstream nations for fresh water, the effect of drier conditions and consequent changes in the transboundary streamflow regime induced by anthropogenic interventions and disasters leads to uncertainty in regional water security. As a case in point, we analyze Jordan's surface water resources and agricultural water demand through 2100, considering the combined impacts of climate change and land-use change driven by the Syrian conflict. We use bias-corrected regional climate simulations as input to high-resolution hydrologic models to assess three drought types: meteorological (rainfall decrease), agricultural (soil moisture deficit), and hydrologic (streamflow decline) under future scenarios. The historical baseline period (1981-2010) is compared to the future (2011-2100), divided into three 30-year periods. Comparing the baseline period to 2070-2100, average temperature increases by 4.5°C, rainfall decreases by 30%, and multiple drought-type occurrences increase from ~8 in 30 years to ~25 in 30 years. There is a significant increase in the contemporaneous occurrence of multiple drought types along with an 80% increase in simultaneous warm and dry events. Watershed simulations of future transboundary Yarmouk-Jordan River flow from Syria show that Jordan would receive 51 to 75% less Yarmouk water compared to historical flow. Recovery of Syrian irrigated agriculture to pre-conflict conditions would produce twice the decline in transboundary flow as that due to climate change. In Jordan, the confluence of limited water supply, future drought, and transboundary hydrologic impacts of land use severely challenges achieving freshwater sustainability.

  13. A review of midwifery education curriculum documents in Jordan.

    There is worldwide recognition that midwives are specialists in normal pregnancy, labour and birth and the postnatal period and that they should be educated to be primary providers of maternity care. In Jordan midwives currently have limited opportunities to fulfil this role. Since the mid-1980s, two public community colleges have offered three-year diploma midwifery education programmes in two major cities in Jordan. In 2002 the first and only four-year bachelor of midwifery education programme was established in one public university. A review to describe the design and content of midwifery education programmes in Jordan and address the question: Does the design of midwifery education programmes in Jordan encourage confidence that graduates will be competent to practise to the full capacity of the internationally defined role and scope of practice of the midwife and undertake the role of primary maternity care providers for women with low-risk pregnancies? A review of Jordanian midwifery education curriculum documents was undertaken using information and documents provided by midwifery programme coordinators. Programme coordinators in all institutions in Jordan providing midwifery education programmes. The curriculum documents reflected a medical model, with an emphasis on illness and intervention rather than preparation for the internationally defined full role and scope of practice of the midwife. This study provides a profile of midwifery education curriculum documents in Jordan with recommendations for changes that would position midwives as potential primary maternity care providers for women in Jordan who have uncomplicated pregnancies.

    The classification of medicine as Prescription-Only-Medicine (POM) and Over-The-Counter (OTC) drugs in Jordan is present but not yet enforced on community pharmacies, the fact that allows access of the public to a wider range of medications that otherwise are provided only on prescription. This, of course, has its implications on safety and effectiveness of the pharmacotherapy in question. This research aims to establish a baseline data concerning the extent of self-medication among Jordanians, and to assess possible factors associated with self-medication, so that future interventions can be documented and planned. A total of 155 out of Amman's 900 community pharmacies. A cross-sectional observational study using a pre-piloted questionnaire was conducted. Over 800 customers who visited the pharmacies over a period of 4 months were interviewed and their non-prescription drug requests patterns were recorded to assess the prevalence of self-medication and offered justification. Self-medication was a common practice among Jordanians (42.5%). The variable that was associated with extent of self-medication was respondents' age, where patients younger than 16 years and those older than 60 years were less likely to self-treat. The most common reasons for self-medication were that the ailments were too minor to see a doctor (46.4%), the long waiting time to be seen by doctors (37.7%) and avoiding the cost of doctors' visits (31.4%). People tended to select medication based on advice received from pharmacy staff (14.2%), friends/neighbors (17.6%) or informal advice from other health professionals like dentists and nurses (21.9%). Alternatively, patients selected products based on their previous experiences with similar symptoms (27%) or similar diseases (33.5%). Self-medication is a common health care practice in Jordan, where people are becoming increasingly familiar with drugs and their brand names. Self-medication behavior varied significantly with a number of socio

    1996-12-31

    Five coals representing four distinct coal sources blended at a midwestern power station were subjected to detailed analysis of their Hardgrove grindability. The coals are: a low-sulfur, high volatile A bituminous Upper Elkhorn No. 3 coal (Pike County, KY); a medium-sulfur, high volatile A bituminous Pittsburgh coal (southwestern PA); a low-sulfur, subbituminous Wyodak coal from two mines in the eastern Powder River Basin (Campbell County, WY). The feed and all samples processed in the Hardgrove grindability test procedure were analyzed for their maceral and microlithotype content. The high-vitrinite Pittsburgh coal and the relatively more petrographically complex Upper Elkhorn No. 3 coal exhibit differing behavior in grindability. The Pittsburgh raw feed, 16x30 mesh fraction (HGI test fraction), and the {minus}30 mesh fraction (HGI reject) are relatively similar petrographically, suggesting that the HGI test fraction is reasonably representative of the whole feed. The eastern Kentucky coal is not as representative of the whole feed, the HGI test fraction having lower vitrinite than the rejected {minus}30 mesh fraction. The Powder River Basin coals are high vitrinite and show behavior similar to the Pittsburgh coal.

  18. Prehistoric cultural ecology in southern jordan.

    PubMed

    Henry, D O

    1994-07-15

    Research in the mountains of southern Jordan resulted in the discovery of 109 archaeological sites that are from the Lower Paleolithic to the Chalcolithic period [150 to 6 thousand years ago (ka)]. Beginning with the Middle Paleolithic (70 ka) two site types (long-term and ephemeral camps) are recognized. Long-term sites have larger areas, thicker deposits, higher artifact densities, and more abundant archaeological features than ephemeral sites. Their natural settings (elevation and exposure) and associated seasonal evidence (phytolith and cementum increment data) indicate that long-term sites were occupied during the winter, wet season and ephemeral sites during the warm, dry season. These differences in site use and seasonality likely reflect an adaptive strategy of transhumance that persisted to modern Bedouin times. At the end of the Pleistocene, the onset of warmer, drier conditions induced a shift of the long-term winter camps from relatively low (800 to 1000 meters above sea level) to high (1000 to 1250 meters above sea level) elevations and largely reversed the earlier transhumant pattern.

  19. The performance of water utilities in Jordan.

    Al-Assa'd, Tamer; Sauer, Johannes

    2010-01-01

    This paper aims to measure the relative performance of Jordan's water utilities for water sector (WS) and wastewater sector (WWS), and to investigate the major factors behind their inefficiencies. DEA (non-parametric method) and Tobit model (parametric method) were used at two stages. At the first stage DEA was used to evaluate the utilities' efficiency and to investigate the utilities' scale effect on efficiency. At the second stage Tobit model (regression) is applied to determine the impact of the non-controllable factors on utilities' inefficiencies where the efficiency score is the dependent variable in the regression. The results of DEA showed that there is a potential to reduce inputs level: water supply and operational expense (OPEX) for WS, and treated wastewater and OPEX for WWS, by around 15-20 and 23-27%, respectively. Aqaba and Jarash utilities are the most efficient utilities in the WS, while it is Amman utility in the WWS. The utility size has relatively moderate effect on the relative performance. It is concluded that the medium utility size for WS and large utility size for WWS is the most appropriate. Tobit model results indicate that commercialization activities have a clear positive impact on efficiency improvement for both sectors.

    2008-12-01

    The objectives of this study were to review etiologies of trauma, associated injuries, diagnosis, management, and outcomes of patients with vascular injuries in the extremities and relate factors in their treatment to the outcome of the injured extremity. Data were collected retrospectively on 73 patients diagnosed to have upper and lower limbs arterial injuries at King Abdullah University Hospital, Jordan, between 2001 and 2006. Factors evaluated included demographic data, location of vessels injured, mechanism of injury, associated injuries, treatment, and outcome. Patients were predominantly males (54 patients). Isolated vascular trauma was present in 36 patients, while in the remaining 37 patients vascular trauma was aggravated by concomitant injuries. The most common etiology of vascular injuries in the upper and lower extremities was a penetrating injury found in 38 patients (52%). The vessels most commonly involved were the femoral and brachial arteries. Various associated injuries were identified mainly orthopedic in 21 patients (29%) and nerve injuries in 18 patients (25%). Autogenous vein graft interposition was mostly performed in 32 patients (44%). Permanent disability was seen in 8 patients (11%), limb amputation was performed in 5 patients (7%). Five patients died due to associated intraabdominal, thoracic, and head injuries giving a mortality rate of 7%. Delay in surgery, blunt trauma and extensive soft tissue defect in combined orthopedic and vascular injuries were associated with increased risk of amputation, while associated nerve injuries and bone injuries with extensive soft tissue damage are risk factors of poor quality outcome.

    2009-05-01

    To assess dentist-assistant interaction and communication styles and their associated factors in Jordan. Three different areas in Amman where private dental clinics heavily cluster were chosen. The researcher visited all dental clinics in these areas and invited dentists to participate in this study. A structured self-administered questionnaire was designed and included the 22 items on staff communication that were used by Gorter and Freeman to assess communication styles. The culturally adapted items were analysed in such a way to reflect the structure that is used in the original study. There was a significant interaction between dentist's gender and communication styles (F = 3.8, P = 0.022). The only significant difference between men and women was for professional leadership style (P = 0.011) where men were more likely to adopt professional leadership style than women. For men, the average score for friendly leadership style was significantly lower than that for other styles. For women, the average score was the highest for gender interacting style which was significantly higher than that for friendly leadership style and professional interacting style, but not business leadership style. Communication and interaction styles between Jordanian dentists and their assistants differ according to gender. Jordanian dentists are less likely to adopt friendly leadership communication style compared with other styles.

    The practice of pharmacy, as well as pharmacy education, varies significantly throughout the world. In Jordan, Kuwait, and Saudi Arabia, the profession of pharmacy appears to be on the ascendance. This is demonstrated by an increase in the number of pharmacy schools and the number of pharmacy graduates from pharmacy programs. One of the reasons pharmacy is on the ascendance in these countries is government commitment to fund and support competitive, well-run pharmacy programs. In this report we describe pharmacy education in 3 Middle East countries: Jordan, Kuwait, and Saudi Arabia. All 3 countries offer bachelor of pharmacy (BPharm) degrees. In addition, 2 universities in Jordan and 1 in Saudi Arabia offer PharmD degree programs. The teaching methods in all 3 countries combine traditional didactic lecturing and problem-based learning. Faculties of pharmacy in all 3 countries are well staffed and offer competitive remuneration. All 3 countries have a policy of providing scholarships to local students for postgraduate training abroad. The majority of students in Jordan and Kuwait are female, while the ratio of male to female students in Saudi Arabia is even. Students’ attitudes towards learning are generally positive in all 3 countries. In Saudi Arabia and Kuwait, most pharmacy graduates work in the public sector, while in Jordan, the majority work in the private sector. PMID:17136159

    The epidemiological characteristics of retinoblastoma have been extensively studied in developed countries, however epidemiological data is scarce in the Middle East. We present a de- tailed epidemiological analysis of retinoblastoma in Jordan in an attempt to aid national and regional strategies for improved cancer surveillance and control. Retrospective review of retinoblastoma cases presenting to the sole and exclusive ocular oncology referral center in Jordan. Forty children (59 eyes) presenting with clinically and/or histologically confirmed retinoblastomas were treated at King Hussein Cancer Center (Amman, Jordan) between January 2006 and December 2010. This case series included 28 boys and 12 girls. Data relating to age at diagnosis, laterality, gender, treatment modality and survival were recorded. The mean age-adjusted incidence of retinoblastoma in Jordan was 9.32 cases per million children per year for children aged 0-5 years. The male: female ratio was 2.3:1. Bilateral cases were encountered in 19 pa- tients (47.5%) while 21 patients (52.5%) harbored unilateral retinoblastoma. At the time of follow-up, 38 patients (95%) were alive. Overall, 40 eyes (67.8%) were successfully preserved without the need for enucleation. The national epidemiological data gathered in this study indicates that the incidence of retinoblastoma in Jordan is similar to that reported in various countries of the world. Jordanian boys, however, are at significantly higher risk for developing retinoblastoma than age-matched girls. Furthermore, Jordanian patients are more likely to harbor bilateral retinoblastoma.

    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

  5. Amassing power in a northern landscape: J. B. Duke and the development of the Saguenay River, 1897-1927

    NASA Astrophysics Data System (ADS)

    Massell, David Perera

    Beginning at the turn of the century, Chapter One reconstructs the process by which the Provincial Government of Quebec sold--individually, outright, and cheaply--the waterfalls and rapids strung out along the length of the Saguenay River. The small-scale Canadian power projects stalled, however, for want of capital or power customers in a remote North American region. A major shift in developmental scale ensues in Chapter Two as a Canadian who owned riparian rights, Thomas "Carbide" Willson, uncorks a genie of American capital in industrialist J. B. Duke. While Duke was invited to participate in the Saguenay's development as a third party, Chapter Three describes how the aggressive New York trader seizes the entire length of the river for his exclusive use. Chapter Four recounts the unexpectedly stiff resistance to the industrial plans of Duke's lieutenants by a young French-Canadian engineer named Arthur Amos, head of Quebec's newly established Hydraulic Service. Stymied in Quebec City, Duke nonetheless proves remarkably agile in the broader theater of multinational enterprise. As Chapter Five documents, Duke succeeds in rounding up an array of industrial power customers to justify the enormous cost of his dams, most notably Delaware-based explosives manufacturer E. I du Pont de Nemours Powder Company. Ultimately Du Pont gets cold feet, and Duke's giant electrochemical scheme collapses around him at the end of 1915. Only after 1920, in Chapter Six, is Duke able to proceed with his project in a changed political and business climate of the postwar period. Contemplating aluminum manufacture by his own company, in Chapter Seven, he attempts to procure the requisite supply of high grade bauxite. But he encounters ferocious competition for possession of the essential raw material. Choosing to merge rather than fight, Duke and Alcoa's President Arthur Vining Davis ally in 1925. Their deal sealed, the two businessmen send their Canadian lawyer to Quebec City to sidestep

    A major challenge facing hydropower operators in today`s complex environment is making management decisions among conflicting objectives. To complicate the problem, many of these objectives are subjective by nature and, thus, are difficult to quantify. Fuzzy set theory creates a quantitative medium in which imprecise or ambiguous objectives can be characterized. Fuzzy membership functions for each objective or constraint can be combined to suggest the best solution. This methodology is applied to the dilemma which currently confronts reservoir operators at Flaming Gorge Dam, located on the Green River in northeastern Utah. The problem is how to balance hydropower objectives with needs of downstream recreationists, endangered fish, riparian vegetation and others. Construction of the membership functions from surveys of experts and estimation of the degree of variation within the functions are discussed. Preliminary results are also presented.

    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.

    2006-02-01

    To describe the development and introduction of patient education materials in a primary care setting in Jordan. During the 2003-2004 academic year, the authors collaborated to produce more than 25 Arabic language written patient education materials designed to conform to cultural and social norms and expectations. Patient education materials were frequently shared with friends and family members. Readability of materials was judged to be excellent when materials were presented at approximately a sixth grade reading level. Patient education materials are greatly needed in Jordan. A thorough understanding of the culture facilitates alignment of the health message with social norms and establishment of credibility with the target audience. The materials developed were well received by patients and physicians. The routine integration of patient education into all medical consultations in Jordan is an important goal. Practice based research will be vital in identifying and eliminating barriers to the introduction of patient education in the clinical setting.

    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.

    Ethnic differences in disease susceptibility and drug response necessitate the participation of the community in biomedical research. Public involvement includes the donation of biospecimens for basic and translational research with a focus on understanding the molecular make-up of individuals. A growing strategy that fosters public involvement is establishing biobanks that serve as a focal point for sample collection, storage, and dissemination. A biobank's success is dependent on the availability of high-quality biospecimens, as well as accessibility of personal and medical data. Diverse public participation in biobanks is also as critical. Due to lack of data related to public knowledge and attitude towards biospecimen-based research and their willingness to participate in biobanking, a structured questionnaire was conducted at the national level. Data were collected from 3196 individuals aged 18 and above, constituting a representative sample of the Jordanian population. Demographic data included age, gender, and education level. Although there was lack of knowledge of the term "biological samples," 80% of respondents approved the use of biospecimens in research. In addition, almost two-thirds of respondents agreed to donate both biospecimens and relevant information for biobanking. Approval of biospecimen-based research and willingness to participate in biobanking significantly correlated with younger age and increasing education, but not gender. Our results provide an insight into the perception of biobanking among the Jordanian population and strengthen the importance of educating the public about research and the value of biobanking. The data should enable researchers in Jordan and surrounding countries of similar culture to lay the foundation for a successful biobank and research program.

    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. 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). 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). 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.

    Immunization can contribute to a dramatic reduction in number of vaccine-preventable diseases among children. The aim of this study is to investigate mothers’ awareness about child vaccines and vaccination in Jordan. This study was a community-based, cross-sectional study that was performed at public places in Irbid City. Data was collected from 506 mothers. After verbal approval, mothers were interviewed to assess their knowledge, attitudes, and practice toward vaccination. Results show that majority of mothers had acceptable knowledge and positive attitude toward vaccination. Most of mothers (94.7–86.8%) were able to identify vaccines that are mandatory as per the national vaccination program. Lower knowledge was observed among mothers (71.6%) for HIB vaccination being mandatory. Most mothers (97.2%) had vaccination card for their baby form the national vaccination programs. Vaccination delay was reported by about 36.6% of mothers and was shown to be associated with significantly (P = 0.001) lower vaccination knowledge/attitude score. Additionally, mothers who reported to be regularly offered information about vaccination during visits and those who identified medical staff members as their major information source had significantly higher vaccination knowledge/attitude score (P = 0.002). In conclusion, vaccination coverage rate is high; however, some aspects of knowledge, attitudes, and practice of vaccination need to be improved. Knowledge and attitudes of mothers were directly associated with their practice of vaccination. Medical staff education about vaccination during each visit seems to be the most effective tool that directly reflects on better practice of vaccination such as reducing the possibility for vaccination delay.

    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.

    It is well known that the quantiles of annual peak flows (floods) are related as power law functions of basin drainage areas. These relationships constitute the basis for the current methods of regional flood frequency estimation. It is less well known that flood events obey similar laws but with different and varied (from event to event) parameters. It has also been demonstrated that power law probability distributions offer very good fit to flood data and lead to more conservative estimates of extreme events compared to the standard methods. The authors review some of the previous findings and show additional analyses of temporal flood data from Iowa. They supplement the data-based analyses with simulations from a space-time model. The overall goal of the research is to connect the spatial and temporal aspects of flood genesis and improve our understanding of the physical aspects that control flood frequency.

    Thousands of people are familiar with that part of Snake River where it flows for more than 300 miles in a general westward course across the plains of southern Idaho, but few have traversed the river where it flows northward and for 200 miles forms the boundary between Idaho and Oregon and for 30 miles the boundary between Idaho and Washington. Below the mining town of Homestead, Oreg., which is the end of a branch line of the Oregon Short Line Railroad, Snake River finds its way through the mountain ranges that seem to block its way to Columbia River in a canyon which, though not so well known, so majestic, nor so kaleidoscopic in color, is in some respects worthy of comparison with the Grand Canyon of the Colorado, for at some places it is deeper and narrower than the Grand Canyon at El Tovar. The Snake, unlike the Colorado, can be reached at many points through the valleys of tributary streams, and the early prospectors no doubt thoroughly explored all parts of the canyon. To traverse the river between Homestead, Oreg., and Lewiston, Idaho, is, however, a difficult undertaking and there are only a few records of boat journeys through the entire stretch. It has long been known that this portion of Snake River contains large potential water powers, but until recently no detailed surveys or examinations covering the entire stretch of the river had been made to determine their location or extent. A railroad has been proposed between Homestead and Lewiston which would provide a direct connection between the railroad systems of northern and southern Idaho. One function of the Geological Survey is to determine the possible interface between transportation routes on land and potential water-power development, and the information set forth in this paper has a bearing on that problem.

  20. Current and Potential Future Bromide Loads from Coal-Fired Power Plants in the Allegheny River Basin and Their Effects on Downstream Concentrations.

    PubMed

    Good, Kelly D; VanBriesen, Jeanne M

    2016-09-06

    The presence of bromide in rivers does not affect ecosystems or present a human health risk; however, elevated concentrations of bromide in drinking water sources can lead to difficulty meeting drinking water disinfection byproduct (DBP) regulations. Recent attention has focused on oil and gas wastewater and coal-fired power plant wet flue gas desulfurization (FGD) wastewater bromide discharges. Bromide can be added to coal to enhance mercury removal, and increased use of bromide at some power plants is expected. Evaluation of potential increases in bromide concentrations from bromide addition for mercury control is lacking. The present work utilizes bromide monitoring data in the Allegheny River and a mass-balance approach to elucidate bromide contributions from anthropogenic and natural sources under current and future scenarios. For the Allegheny River, the current bromide is associated approximately 49% with oil- and gas-produced water discharges and 33% with coal-fired power plants operating wet FGD, with 18% derived from natural sources during mean flow conditions in August. Median wet FGD bromide loads could increase 3-fold from 610 to 1900 kg/day if all plants implement bromide addition for mercury control. Median bromide concentrations in the lower Allegheny River in August would rise to 410, 200, and 180 μg/L under low-, mean-, and high-flow conditions, respectively, for the bromide-addition scenario.

  1. Application of techniques to identify coal-mine and power-generation effects on surface-water quality, San Juan River basin, New Mexico and Colorado

    Numerous analytical techniques were applied to determine water quality changes in the San Juan River basin upstream of Shiprock , New Mexico. Eight techniques were used to analyze hydrologic data such as: precipitation, water quality, and streamflow. The eight methods used are: (1) Piper diagram, (2) time-series plot, (3) frequency distribution, (4) box-and-whisker plot, (5) seasonal Kendall test, (6) Wilcoxon rank-sum test, (7) SEASRS procedure, and (8) analysis of flow adjusted, specific conductance data and smoothing. Post-1963 changes in dissolved solids concentration, dissolved potassium concentration, specific conductance, suspended sediment concentration, or suspended sediment load in the San Juan River downstream from the surface coal mines were examined to determine if coal mining was having an effect on the quality of surface water. None of the analytical methods used to analyzed the data showed any increase in dissolved solids concentration, dissolved potassium concentration, or specific conductance in the river downstream from the mines; some of the analytical methods used showed a decrease in dissolved solids concentration and specific conductance. Chaco River, an ephemeral stream tributary to the San Juan River, undergoes changes in water quality due to effluent from a power generation facility. The discharge in the Chaco River contributes about 1.9% of the average annual discharge at the downstream station, San Juan River at Shiprock, NM. The changes in water quality detected at the Chaco River station were not detected at the downstream Shiprock station. It was not possible, with the available data, to identify any effects of the surface coal mines on water quality that were separable from those of urbanization, agriculture, and other cultural and natural changes. In order to determine the specific causes of changes in water quality, it would be necessary to collect additional data at strategically located stations. (Author 's abstract)

    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.

    A model for pain relief and palliative care for the Middle East has been established in Jordan. King Hussein Cancer Centre (KHCC) in Amman is now a truly comprehensive cancer center as it includes palliative care for inpatients, outpatients, and patients at home. This is especially important in a country and a region where over 75% of the cancer patients are incurable when diagnosed. To support effective palliative care delivery, there have been many significant changes in Jordan between 2001 and 2006. Regulations governing opioid prescribing have been changed to facilitate effective pain management. The national opioid quota has been increased. Cost-effective, generic, immediate-release morphine tablets are being produced in Jordan. Intensive, interactive bedside training courses for doctors, nurses, and clinical pharmacologists have started to overcome opiophobia and motivate health care professionals to take up palliative care as a profession. "Champions" for palliative care have emerged who are leading the development of palliative care in Jordan's health care systems and starting to support neighboring countries to develop pain relief and palliative care. While before 2003, fewer than 250 patients per year received palliative care, by 2006 more than 800 patients per year were receiving pain relief and palliative care through the KHCC and Al Basheer Hospital. The achieved changes and the unusually rapid and effective institutionalization of palliative care serve as a model for other countries in the Middle East region as to what should be done and how.

    Using the Jordan algebras methods, specially the properties of Peirce decomposition and the Frobenius transformation, we compute the coefficients of the zeta functional equation, in the case of Jordan algebras of type II. As particular cases of our result, we can cite the case of studied by Gelbart [Mem. Amer. Math. Soc. 108 (1971)] and Godement and Jacquet [Zeta functions of simple algebras, Lecture Notes in Math., vol. 260, Springer-Verlag, Berlin, 1972], and the case of studied by Muro [Adv. Stud. Pure Math. 15 (1989) 429]. Let us also mention, that recently, Bopp and Rubenthaler have obtained a more general result on the zeta functional equation by using methods based on the algebraic properties of regular graded algebras which are in one-to-one correspondence with simple Jordan algebras [Local Zeta Functions Attached to the Minimal Spherical Series for a Class of Symmetric Spaces, IRMA, Strasbourg, 2003]. The method used in this paper is a direct application of specific properties of Jordan algebras of type II.

    Introduction: Although water pipe tobacco smoking is common in Lebanon and Syria, prevalence in neighboring Jordan is uncertain. The purposes of this study were (a) to assess the prevalence of water pipe tobacco smoking among university students in Jordan and (b) to determine associations between sociodemographic variables and water pipe tobacco smoking in this population. Methods: A trained interviewer administered a questionnaire among randomly selected students at four prominent universities in Jordan. The questionnaire assessed sociodemographic data, personal history of water pipe tobacco use, and attitudes regarding water pipe tobacco smoking. We used logistic regression to determine independent associations between sociodemographic and attitudinal factors and each of two dependent variables: ever use of water pipe and use at least monthly. Results: Of the 548 participants, 51.8% were male and mean age was 21.7 years. More than half (61.1%) had ever smoked tobacco from a water pipe, and use at least monthly was reported by 42.7%. Multivariable analyses controlling for all relevant factors demonstrated significant associations between ever use and only two sociodemographic factors: (a) gender (for women compared with men, odds ratio [OR] = 0.11, 95% CI = 0.07–0.17) and (b) income (for those earning 500–999 Jordanian dinar (JD) monthly vs. <250 JD monthly, OR = 2.37, 95% CI = 1.31–4.31). There were also significant associations between perception of harm and addictiveness and each outcome. Discussion: Water pipe tobacco smoking is highly prevalent in Jordan. Although use is associated with male gender and upper middle income levels, use is widespread across other sociodemographic variables. Continued surveillance and educational interventions emphasizing the harm and addictiveness of water pipe tobacco smoking may be valuable in Jordan. PMID:20418383

    Advances in remote-sensing technology allow for cost-effective, accurate, high-resolution mapping of river-channel topography and shallow aquatic bathymetry over large spatial scales. A combination of near-infrared and green spectra airborne laser swath mapping was used to map river channel bathymetry and watershed geometry over 90+ river-kilometers (75-1175 km2) of the Greys River in Wyoming. The day of flight wetted channel was identified from green LiDAR returns, and more than 1800 valley-bottom cross-sections were extracted at regular 50-m intervals. The bankfull channel geometry was identified using a "watershed-based" algorithm that incrementally filled local minima to a "spill" point, thereby constraining areas of local convergence and delineating all the potential channels along the cross-section for each distinct "spill stage." Multiple potential channels in alluvial floodplains and lack of clearly defined channel banks in bedrock reaches challenge identification of the bankfull channel based on topology alone. Here we combine a variety of topological measures, geometrical considerations, and stage levels to define a stage-dependent bankfull channel geometry, and compare the results with day of flight wetted channel data. Initial results suggest that channel hydraulic geometry and basin hydrology power-law scaling may not accurately capture downstream channel adjustments for rivers draining complex mountain topography.

    The Kursk TETs-1 heating and electric power plant is discussed as an illustration of preventing thermal contamination of its water supply (River Seim) by circulating water. An effective water supply system is taken to be one for which the overheating of the water at a monitoring site (near the outlet location) does not exceed an approved level for the water use conditions. The required cooling capacity of a spray pond for circulating and flow-through water supplies is determined.

  6. Increasing drought in Jordan: Climate change and cascading Syrian land-use impacts on reducing transboundary flow

    In countries where severe drought is an anticipated effect of climate change and in those that heavily depend on upstream nations for fresh water, the effect of drier conditions and consequent changes in the transboundary streamflow regime induced by anthropogenic interventions and disasters leads to uncertainty in regional water security. As a case in point, we analyze Jordan’s surface water resources and agricultural water demand through 2100, considering the combined impacts of climate change and land-use change driven by the Syrian conflict. We use bias-corrected regional climate simulations as input to high-resolution hydrologic models to assess three drought types: meteorological (rainfall decrease), agricultural (soil moisture deficit), and hydrologic (streamflow decline) under future scenarios. The historical baseline period (1981–2010) is compared to the future (2011–2100), divided into three 30-year periods. Comparing the baseline period to 2070–2100, average temperature increases by 4.5°C, rainfall decreases by 30%, and multiple drought-type occurrences increase from ~8 in 30 years to ~25 in 30 years. There is a significant increase in the contemporaneous occurrence of multiple drought types along with an 80% increase in simultaneous warm and dry events. Watershed simulations of future transboundary Yarmouk-Jordan River flow from Syria show that Jordan would receive 51 to 75% less Yarmouk water compared to historical flow. Recovery of Syrian irrigated agriculture to pre-conflict conditions would produce twice the decline in transboundary flow as that due to climate change. In Jordan, the confluence of limited water supply, future drought, and transboundary hydrologic impacts of land use severely challenges achieving freshwater sustainability. PMID:28875164

  7. Landscape development in the context of soil distribution in Jordan

    NASA Astrophysics Data System (ADS)

    Lucke, Bernhard

    2016-04-01

    Processes of landscape change can be assessed by studying the distribution of soil types and their connection to climate, the geology, and land use. In this context, even in areas where no virgin soils are available, paleosols pre-dating the introduction of agriculture can be utilized for estimating potential soil development without human impact. Soil distribution in Jordan follows closely the climate and topography: specific soil orders can be found within the dry and hot subtropical, subhumid-semiarid, semiarid-arid, and arid regions. The pattern of soil and paleosol distribution in Jordan points to an important role of the geology (bedrock and relief), and of climate in their formation, both locally such as in the vicinity of the ancient site of Abila, and regionally in the whole country. In contrast, the impact of land use appears relatively limited: overall erosion has been estimated not to exceed the expected geological rate, and Jordan is considered to be in the stable state of completed geologic erosion. This is further supported by strongly varying soil properties and archaeological material on agricultural fields, which suggests that overall erosion processes during historical periods were limited. The presence of a quite uniform 4 m thick loess cover around the site of Umm el-Jimal in north-east Jordan suggests that aeolian deposits are probably the by far dominating parent material of current soils in northern Jordan. In this context, an apparent division of some soil profiles into subsoil and topsoil could correspond to dominant in-situ soil formation out of bedrock weathering at the bottom, while the upper part of the profiles could correspond to aeolian dust as main parent material. A stone line or lithological discontinuity separating these two parts of the profile might refer to a major erosion event. If true, this could indicate that current soils in Jordan might represent a mixture of at least two phases of soil development with probably

    A non-seasonal diarrhoeal episode in the Jordan Valley occurred over a 2-month period, during which no traditional enteropathogens were detected by the health authority laboratories. A total of 17 diarrhoeal stool specimens from infants, young children and adults were randomly collected and delivered to our laboratories to investigate the presence of unusual aetiological agents. Stools were examined for parasites, ova, viruses and cultured for bacterial pathogens. A multiplex polymerase chain reaction was developed to investigate the involvement of diarrhoeagenic Escherichia coli in this episode. Recognised pathogenic organisms were detected in 8 out of 17 of the diarrhoeatic patients, one patient of whom had a mixed infection with two agents. Rotavirus, enteroinvasive E. coli (EIEC), enteropathogenic E. coli (EPEC), and enterotoxigenic E. coli (ETEC) were found to be associated with the diarrhoea. EIEC was the most common enteropathogen detected (4 out of 17) followed by rotavirus (3 out of 17). One of the EIEC isolates detected in one patient was associated with rotavirus. The clinical features of the diarrhoeatic patients were remarkably similar, regardless of aetiology. This study reveals the identity of pathogenic agents that are not detected by traditional methods employed by the health authority laboratories, which emphasise the urgent need for developing the current diagnostic techniques.

    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.

    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.

    Despite their considerable growth in last few decades, emerging markets (EM) face numerous risks that have the potential to slow down or obstruct their development. Three main issues are discussed in this paper: first, the risks facing organisations operating in emerging markets and Jordan in particular; secondly, the role of business continuity management (BCM) in emerging markets; and thirdly, potential factors that underpin the role of BCM in emerging markets. These issues are significant, as they represent the role of BCM in highly dynamic and fast changing business environments. The paper provides a discussion of the significance of BCM in reducing or preventing risks facing organisations operating in emerging markets, especially those in Jordan.

    Oweis, Arwa I

    2005-12-01

    The definition of a profession consists of contributing characteristics. Nursing must achieve these characteristics in order to confirm its professional status. These characteristics include: a standard of education; professional organizations; commitment; autonomy; continuing education; body of knowledge and competencies; social value; and a code of ethics. Nursing in Jordan faces a unique set of challenges to meet these criteria. The purpose of this discussion is to bring the professional challenges of nursing in Jordan to light, to motivate collaborative efforts to remediate them and to discuss the value of evidence-based practice in this process. The key to confirming Jordanian nurses' professional status is for nurses to seek every opportunity to prove themselves, earn respect, take control over their work, support their colleagues and to make informed decisions. In addition, a more active and effective role for the nursing organizations is necessary to change the public's view of nursing. Efforts to reform regulation also should be intensified.

    2010-01-01

    The present study evaluates a major education reform in Jordan—the implementation of public kindergartens—and provides an example of how evaluation can be incorporated into education reform. In the context of education reform in Jordan, 532 public kindergartens have been created over the last five years. A stratified random sample of kindergartens was selected to represent these new public kindergartens (n = 84) and previously existing private kindergartens (n = 23). Independent observers rated the quality of kindergarten environments in seven domains. Overall, 13% of public kindergarten environments were observed to be inadequate, 43% were of minimal quality, 43% were good, and 1% were excellent. In four of the seven domains, the quality of public kindergartens was significantly higher than the quality of private kindergartens; there were no significant differences in the other domains. Findings suggest the importance of continuing to implement high quality kindergartens in Jordan and of incorporating evaluations into education reform. PMID:21170163

    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.

    The present study has investigated the occurrence of body image dissatisfaction among adolescent schoolgirls in Amman, Jordan, and the risk factors that are known to predispose it including individual, familial and social variables. A sample of 326 adolescent girls aged 10-16 years was recruited from public and private schools in Amman. Participants completed a socio-demographic data sheet, eating attitude test, and body shape questionnaire. Approximately, 21.2% of participants displayed body image dissatisfaction in which physical changes associated with puberty and exhibiting negative eating attitudes were associated with this dissatisfaction. Additionally, mass media messages, as well as peers and family pressures towards thinness were associated with participants' preoccupation with their body image. In conclusion, negative body image perception was observed in the present sample. Therefore, well-controlled prospective studies and development of intervention programs on body image among adolescent girls in Jordan are needed. Copyright 2009 Elsevier Ltd. All rights reserved.

    1999-04-01

    The aim of this study is to assess the seismic hazard in the eastern Mediterranean and Sinai region using a probabilistic approach. An updated earthquake catalogue for the period 1 to 1993 AD that covers the area between latitude 27°-37°N and longitude 32°-39°E, has been used. Using the new seismic-tectonic map for the area, 10 line-sources are delineated. These lines or fault zones are thought to represent the main sources for the seismic potential in the area. The results are demonstrated as iso-contour lines of the peak-ground acceleration. The iso-acceleration contours represent 90% probability that these peak values will not be exceeded over periods of 50, 100 and 200 years, respectively. This study concludes that the seismic hazard severity is highest along the Jordan Dead Sea transform fault system, namely from south of the Gulf of Aqaba, Dead Sea-Jordan River, Tiberia Lake, Rachaya, Ed Damur, Yammuneh Fault, and Ghab Fault in the north. For the 50 year iso-contour map, the major cities of Amman, Damascus, and Beirut lay around the 2 m s -2 contour line, while Jerusalem lies along the 3 m s -2 line. Antakia in Turkey has the highest seismic potential severity (around 5 m s -2) while in Cyprus the maximum hazard is expected to reach 4 m s -2 for the coming 50 years.

    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.

  2. Wage differentials in Jordan: effects on integrated labour market.

    1987-06-01

    The emigration of Jordanian workers has benefited the country by reducing the scale of unemployment that existed in the 1960s and early 1970s. In addition, workers' remittances have had a favorable effect on the Jordanian balance of payments and contributed to increases in wage rates and demands for labor. Any shortages of labor resulting from the emigration flow appear to have been offset by the importation of workers from neighboring countries. A sample survey encompassing 495 foreign workers in Jordan and 518 Jordanian workers indicates that immigrant workers' wages are below those of Jordanian workers and considerably below the wages that Jordanian workers earn abroad. The average monthly wage for the Jordanians in the sample was JD 193.03 compared to JD 132.93 for the immigrants--a 45% difference. Over half of the immigrants surveyed earned under JD 99/month, while only 26% of the Jordanian workers were in this low income category. In part this wage differential is caused by the high proportions of immigrant workers employed in the clerical and unskilled occupational groups, where they are paid only half the wages earned by Jordanians engaged in the same occupations. A similar differential was observed in the average amount of monthly remittances to home countries: in 1982, Jordanians working abroad remitted an average of JD 77.5/worker compared with JD 59/worker remitted by foreign workers employed in Jordan. On balance, it appears that Jordan is a net gainer from the process of labor import and export.

  3. Nursing shortage in Jordan: what is the solution?

    The purpose of this article is twofold: (1) to analyze the forces behind the nursing shortage in Jordan and (2) to propose strategies and policy directions to deal with the nursing shortage in Jordan. Nursing shortage is one of the challenges that the nursing profession faces in general. There should be an adequate number of nurses if quality care is to be maintained. Patient care provided by nurses is the commodity that hospitals provide; therefore, if hospitals worry about the satisfaction of their consumers, they need to learn how to retain an adequate number of nurses. In Jordan, the decline in the number of nurses is a result of slow salary increases for nurses, the fact that fewer women are selecting nursing careers, a decrease in the number of nursing faculty, and unattractive work conditions. Nurse researchers, educators, clinicians, and administrators need to work together to actively deal with the issue of nursing shortage. The "hog cycle" needs to be broken and work conditions need to be improved so that nurses can feel more satisfied and more committed to their profession. Strategies and recommendations to tackle nursing shortage are proposed.

    The aim of this study was to investigate the drug information resources available in community pharmacies in Amman, Jordan. A total of 156 private community (retail) pharmacies in different parts of Amman, the capital of Jordan, were recruited by personal contact. Pharmacists at the sample pharmacies completed a self-administered questionnaire that consisted of two sections. The first section elicited the drug information resources available in their pharmacies. The second section presented five mock medicines information scenarios and asked respondents to identify the most suitable information resource to be used from a given list. Answers then were coded and entered into SPSS for Windows for statistical analysis. All pharmacies had at least one reference book, but most were outdated. The Monthly Index of Medical Specialties (MIMS) was the most commonly found (n = 101; 64.7%), and 40.4% (n = 63) had internet access. Only 19.2% (n = 30) of the respondents reported getting medicines information directly from pharmaceutical companies, usually through pharmaceutical representatives. Most pharmacists could identify appropriate information resources for drug dosing and side effects but did not fare well for medicine identification, drug interactions and primary research evidence. The quality of drug information resources in private community pharmacies in Amman is far from optimal. This will affect the quality of information provided to patients and prescribers and have an adverse effect on the role that pharmacists can play in the health system in Jordan.

    Vitamin D deficiency is well recognized in selected Middle Eastern countries, but neonatal vitamin D status is not well studied in Jordan and other nearby countries. The aim of this study is to determine the prevalence of vitamin D deficiency in Jordanian newborns and risk factors associated with low levels. This is a prospective cohort study of newborn infants who were delivered at the Al Bashir Government Hospital in Amman, Jordan, from January 31, 2010, to January 27, 2011. Heel stick blood samples for 25-hydroxyvitamin D [25(OH)D] levels were obtained within 96 hours of birth. Maternal dress pattern, vitamin supplementation, smoke exposure during pregnancy, mode of delivery, gestational age, and birth weight were documented. Samples were obtained from 3,731 newborns. Median gestational age was 39 weeks, median birth weight was 3.1 kilograms, median maternal age was 27 years, and median newborn 25(OH)D level was 8.6nmol/L. A total of 3,512 newborns (94.1%) in this study were vitamin D deficient (< 50 nmol/L). Lower gestational age, maternal smoke exposure, and birth during winter months were associated with lower infant vitamin D levels, while vitamin D supplementation and time spent outside during pregnancy were associated with higher vitamin D levels. The prevalence of severely low vitamin D levels in newborn infants in Amman, Jordan, is substantial, even in newborns born during the spring and summer months. Vitamin D supplementation is needed in this population.

    Surface heat flow in southern Jordan (western part of the Arabian Plate) was determined in a dense cluster of five, up to 900-m-deep boreholes that have encountered sedimentary rocks of Paleozoic (Ordovician and Silurian) age. These rocks are underlain by an igneous and metamorphic basement, which has been studied for its radiogenic heat production, along the eastern margin of the Dead Sea Transform (DST) fault system. The heat flow, calculated from continuous temperature logs and laboratory-measured thermal conductivity of drillcores and surface samples, averages to 60.3 ± 3.4 mW m -2 and contrasts the common view of the late Proterozoic-consolidated Arabian Shield constituting a low heat-flow province of ⩽45 mW m -2. Although only characterizing an area of about 300 km 2, this average is unlikely representing a positive local anomaly caused by voluminous HHP granites/rhyolites at shallow depths. Instead, a heat flow of 60 mW m -2 is considered a robust estimate of the Phanerozoic conductive surface heat flow not only for Jordan, but for the Arabian Shield in areas unaffected by younger reactivation. The large variation in conductive heat flow (36-88 mW m -2) previously observed in Jordan, southern Syria, and Saudi Arabia is irreconcilable with their broad similarity in lithosphere structure and composition and rather reflects a combination of factors including low-quality temperature data and insufficient knowledge on thermal rock properties.

    The emergence of Middle East Respiratory Syndrome coronavirus (MERS-CoV) has prompted enhanced surveillance for respiratory infections among pilgrims returning from the Hajj, one of the largest annual mass gatherings in the world. To describe the epidemiology and etiologies of respiratory illnesses among pilgrims returning to Jordan after the 2014 Hajj. Surveillance for respiratory illness among pilgrims returning to Jordan after the 2014 Hajj was conducted at sentinel health care facilities using epidemiologic surveys and molecular diagnostic testing of upper respiratory specimens for multiple respiratory pathogens, including MERS-CoV. Among the 125 subjects, 58% tested positive for at least one virus; 47% tested positive for rhino/enterovirus. No cases of MERS-CoV were detected. The majority of pilgrims returning to Jordan from the 2014 Hajj with respiratory illness were determined to have a viral etiology, but none were due to MERS-CoV. A greater understanding of the epidemiology of acute respiratory infections among returning travelers to other countries after Hajj should help optimize surveillance systems and inform public health response practices.

    Steelhead (Oncorhynchus mykiss) populations have declined throughout their range in the last century and many populations, including those of the Snake River Basin are listed under the Endangered Species Act of 1973. The reasons for their decline are many and complex, but include habitat loss and degradation, overharvesting, and dam construction. The 2008 Biological Opinion calls for an increase in the abundance of female steelhead through an increase in iteroparity (i.e., repeat spawning) and this can be realized through a combination of reconditioning and in-river survival of migrating kelts. The goal of this study is to provide the data necessary to inform fisheries managers and dam operators of Snake River kelt migration patterns, survival, and routes of dam passage. Steelhead kelts (n = 487) were captured and implanted with acoustic transmitters and passive integrated transponder (PIT)-tags at the Lower Granite Dam (LGR) Juvenile Fish Facility and at weirs located in tributaries of the Snake and Clearwater rivers upstream of LGR. Kelts were monitored as they moved downstream through the Federal Columbia River Power System (FCRPS) by 15 autonomous and 3 cabled acoustic receiver arrays. Cabled receiver arrays deployed on the dam faces allowed for three-dimensional tracking of fish as they approached the dam face and were used to determine the route of dam passage. Overall, 27.3% of the kelts tagged in this study successfully migrated to Martin Bluff (rkm 126, as measured from the mouth of the Columbia River), which is located downstream of all FCRPS dams. Within individual river reaches, survival per kilometer estimates ranged from 0.958 to 0.999; the lowest estimates were observed in the immediate forebay of FCRPS dams. Steelhead kelts tagged in this study passed over the spillway routes (spillway weirs, traditional spill bays) in greater proportions and survived at higher rates compared to the few fish passed through powerhouse routes (turbines and juvenile

    Accumulation of artificial and natural radionuclides in the chains of food webs leading to non-predatory and piscivorous fish of the Yenisei River was investigated during one year before and three years after the shutdown of a nuclear power plant at the Mining-and-Chemical Combine (2009-2012). The activity of artificial radionuclides in the samples of biota ofthe Yenisei River (aquatic moss, gammarids, dace, grayling, pike) was estimated. The concentration of radionuclides with induced activity (51Cr, 54Mn, 58Co, 60Co, 65Zn, 141, 144Ce, 152, 154Eu, 239Np) decreased in the biomass of biota after the shutdown of the nuclear power plant; the concentration of 137Cs did not. Analysis of the accumulation factors (C(F)) allows us to expect the effective accumulation of 137Cs in the terminal level of the food web of the Yenisei River--pike (C(F) = 2.0-9.4), i.e. biomagnifications of radiocesium. Accumulation of artificial, radionuclides in non-predatory fish from gammarids was not effective (C(F) < 1). An effective accumulation of 40K is possible in muscles of non-predatory and piscivorous fish species from food (C(F) = 2:6-3.1 and 1.3-1.4, respectively). C(Fs) of K and 40K were equal in all trophic pairs, but C(Fs) of 40K and 137Cs differed considerably.

  12. Depositional and diagenetic processes of Qa Khanna playa, North Jordan basaltic plateau, Jordan

    2010-09-01

    The present study explored mineral occurrences and sediment characteristics of playas from northern Jordan and explained depositional and diagenetic processes as reflected from bulk chemistry and sedimentary structures. Mudcracks of different sizes and shape patterns, laminations, intersediment vesicles, and bioturbation pipes are the main sedimentary structures. Plagioclase, olivine, orthopyroxene, nepheline and other opaque minerals are all of detrital origin, and are derived from the basaltic bedrocks surrounding the studied playa. Evaporites are very rare; they are represented only by trace amounts of gypsum. The identified clay minerals in the clay fraction of the studied sediments, arranged according to their decreasing abundances are palygorskite, illite, kaolinite, smectite and chlorite. The elemental abundances were tied to clay, CaCO 3 and nearby igneous rocks. The type of clay minerals, the high pH values of the studied sediments, and the considerable incorporation of Mg and K in palygorskite and illite respectively, may strongly reflect a high evaporative and alkaline environment under arid to semi-arid conditions in an ephemeral lake of the Qa Khanna. Concentrations and distributions of both major and trace elements are essentially controlled by the clay mineralogy and the calcium carbonate content; Ca is mainly incorporated in the CaCO 3, which is either generated authigenically or by aeolian deposition. Fe and K are incorporated and fixed by illite under an evaporative and alkaline environment. Mg is incorporated in palygorskite while Mn is adsorbed on various clay minerals. Sr substitutes for Ca in the aeolian CaCO 3 and its presence in the studied sediments is independent of the prevailing conditions during the playa evolution. Rb substitutes for K in illite under the prevailing chemical conditions in the studied playa.

    The U.S. Department of Energy (DOE) National Energy Technology Laboratory Office of Coal and Environmental Systems has as its mission to develop advanced gasification-based technologies for affordable, efficient, zero-emission power generation. These advanced power systems, which are expected to produce near-zero pollutants, are an integral part of DOE's Vision 21 Program. DOE has also been developing advanced gasification systems that lower the capital and operating costs of producing syngas for chemical production. A transport reactor has shown potential to be a low-cost syngas producer compared to other gasification systems since its high-throughput-per-unit cross-sectional area reduces capital costs. This work directly supports the Power Systems Development Facility utilizing the Kellogg Brown and Root transport reactor located at the Southern Company Services Wilsonville, Alabama, site. Over 3600 hours of operation on 17 different coals ranging from bituminous to lignite along with a petroleum coke has been completed to date in the pilot-scale transport reactor development unit (TRDU) at the Energy & Environmental Research Center (EERC). The EERC has established an extensive database on the operation of these various fuels in both air- and oxygen-blown modes utilizing a pilot-scale transport reactor gasifier. This database has been useful in determining the effectiveness of design changes on an advanced transport reactor gasifier and for determining the performance of various feedstocks in a transport reactor. The effects of different fuel types on both gasifier performance and the operation of the hot-gas filter system have been determined. It has been demonstrated that corrected fuel gas heating values ranging from 90 to 130 Btu/scf have been achieved in air-blown mode, while heating values up to 230 Btu/scf on a dry basis have been achieved in oxygen-blown mode. Carbon conversions up to 90% have also been obtained and are highly dependent on the oxygen

  14. Towards Sustainable Water Management in a Country that Faces Extreme Water Scarcity and Dependency: Jordan

    Jordan faces a great variety of water-related challenges: domestic water resources are scarce and polluted; the sharing of transboundary waters has led to tensions and conflicts; and Jordan is extremely dependent of foreign water resources through trade. Therefore, sustainable water management in Jordan is a challenging task, which has not yet been accomplished. The objective of this study was to analyse Jordan's domestic water scarcity and pollution and the country's external water dependency, and subsequently review sustainable solutions that reduce the risk of extreme water scarcity and dependency. We have estimated the green, blue and grey water footprint of five different sectors in Jordan: crop production, grazing, animal water supply, industrial production and domestic water supply. Next, we assessed the blue water scarcity ratio for the sum of surface- and groundwater and for groundwater separately, and calculated the water pollution level. Finally, we reviewed the sustainability of proposed solutions to Jordan's domestic water problems and external water dependency in literature, while involving the results and conclusions from our analysis. We have quantified that: even while taking into account the return flows, blue water scarcity in Jordan is severe; groundwater consumption is nearly double the sustainable yield; water pollution aggravates blue water scarcity; and Jordan's external virtual water dependency is 86%. Our review yields ten essential ingredients that a sustainable water management strategy for Jordan, that reduces the risk of extreme water scarcity and dependency, should involve. With respect to these, Jordan's current water policy requires a strong redirection towards water demand management. Especially, more attention should be paid to reducing water demand by changing the consumption patterns of Jordan consumers. Moreover, exploitation of fossil groundwater should soon be halted and planned desalination projects require careful

    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

    An analytic description of one decision-making process concerning whether or not to develop the hydroelectric potential of the Boardman River is presented. The focus of the analysis is on the factor that the developers considered, or should consider in making a responsible commitment to small-scale hydroelectric development. Development of the Boardman River would occur at the five dam sites. Two existing dams, owned by the county, previously generated hydroelectricity, as did a third before being washed out. One dam has never been utilized. It is owned by the city which also owns the washed-out area. The study concludes that hydroelectric power is feasible at each. Grand Traverse County and Traverse City would engage in a joint venture in developing the resource. Chapter I presents a detailed description of the developers, the river resource, and the contemplated development. Chapter II is an analysis of the factors affecting the decision making process. Chapter III summarizes the impact of the more significant barriers and incentives and presents recommendations that, if implemented, will favorably affect decisions to develop small-scale hydroelectric generation capability.

    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 (226)Ra (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 (226)Ra 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 (226)Ra in the finer (<53 μm) grain size fraction. Phosphogypsum samples collected from two industrial sites with different sources of phosphate rock feedstock show consistent differences in concentration of (226)Ra 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 (226)Ra. (226)Ra correlates closely with Ba in the water-insoluble residues. Uniformly tiny (<10 μm) 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.

    Objective: Vitamin D deficiency is well recognized in selected Middle Eastern countries, but neonatal vitamin D status is not well studied in Jordan and other nearby countries. The aim of this study is to determine the prevalence of vitamin D deficiency in Jordanian newborns and risk factors associated with low levels. Methods: This is a prospective cohort study of newborn infants who were delivered at the Al Bashir Government Hospital in Amman, Jordan, from January 31, 2010, to January 27, 2011. Heel stick blood samples for 25-hydroxyvitamin D [25(OH)D] levels were obtained within 96 hours of birth. Maternal dress pattern, vitamin supplementation, smoke exposure during pregnancy, mode of delivery, gestational age, and birth weight were documented. Results: Samples were obtained from 3,731 newborns. Median gestational age was 39 weeks, median birth weight was 3.1 kilograms, median maternal age was 27 years, and median newborn 25(OH)D level was 8.6nmol/L. A total of 3,512 newborns (94.1%) in this study were vitamin D deficient (< 50 nmol/L). Lower gestational age, maternal smoke exposure, and birth during winter months were associated with lower infant vitamin D levels, while vitamin D supplementation and time spent outside during pregnancy were associated with higher vitamin D levels. Conclusions: The prevalence of severely low vitamin D levels in newborn infants in Amman, Jordan, is substantial, even in newborns born during the spring and summer months. Vitamin D supplementation is needed in this population. PMID:24373276

    Birth weight is a good indicator of mothers' and neonates' nutritional status, and it contributes to the newborn baby's survival, health, growth and development. This study identified social factors associated with differences in the mean birth weight of newborn babies in Jordan. This retrospective study analysed medical records to determine possible risk factors associated with differences in newborn BW in the Irbid governorate of Jordan. All full-term singleton births during the year 2010 were reviewed. Abstracted data included mother's age, educational level, and monthly family income. Newborn information included birth weight, gender and birth order. A total of 5414 full-term singleton births were included. Of these, 15.1% were low birth weight, 73.6% were normal birth weight, and 11.3% were high birth weight. Bivariate analysis of variance revealed that low mean birth weight was associated with female gender, first-born babies, higher maternal age (>35 years), lower educational level and lower income (<500 JD). Multivariate analysis of variance revealed that mean birth weight was lower in female infants, first-born infants, infants of less educated mothers, higher age and low monthly income. The findings can be generalized to full-term singleton pregnancies in countries who share similar cultural and traditional values. Education of mothers is a modifiable variable that can positively influence birth weight, particularly in the case of female and first-born infants. The findings inform our understanding of some social factors affecting birth weights of neonates in Jordan and development of effective public health interventions that could reduce the adverse effects of such factors on newborn birth weight. Preconception and antenatal care is also important for early detection of such possible risk and targeting mothers who require early interventions and support. © 2014 International Council of Nurses.

  19. Sediment fingerprinting in Northern Jordan - approaching sediment comparability

    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

    It is shown that the Jordan frame and its conformally transformed version, the Einstein frame of nonminimally coupled theories of gravity, are actually equivalent at the quantum level. The example of the theory taken up is the Brans-Dicke theory, and the wave packet calculations are done for a homogeneous and isotropic cosmological model in the purest form of the theory, i.e., in the absence of any additional matter sector. The calculations are clean and exact, and the result obtained are unambiguous.

    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.

    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

    A revised Hopkins Symptom Checklist (HSCL), translated into Arabic, was distributed to a sample of 87 nonpsychotic mental health out-patients in Zarka, Jordan (male = 61, female = 26). Findings revealed no significant gendered differences, but higher responses among women in all dimensions. Regardless of gender, patients also expected and were satisfied with medicinal treatment; explained etiologies as having supernatural origins; and utilized informal community traditional healing and religious healing systems. The supernatural explanations and community healing systems varied by gender. Findings emphasize future treatment and programme development strategies that take into account the biomedical/traditional interface, culturally appropriate treatment modalities, different gendered patient needs, and the potential stigma of professional treatment.

    The prevalence of skin disorders and their relation to age and nationality in Amman, Jordan were determined. Eight schools were selected using a simple random technique and a total of 2788 male schoolchildren were examined. The overall prevalence of skin disorders was 19.23%, with leukonychia (36.66%), naevi (12.88%) and head lice (11.01%) being the most common. Head lice were found more frequently among the Jordanian (11.6%) than non-Jordanian (8.3%) schoolchildren. School health departments must be encouraged to control associated health problems.

    Although osteoporosis is a preventable disease affecting millions of people, public awareness remains low. This study used a pretest-posttest quasi-experimental design to explore osteoporosis knowledge among adolescent female students in Jordan. A questionnaire was administered to 148 students recruited from a secondary school in the city of Irbid before and after a series of health education sessions based on the health belief model. A significant increase in overall scores for osteoporosis knowledge was seen (mean score pretest = 24.1 and posttest = 29.8, P < 0.001). Further research geared toward the follow-up of attained knowledge and behavioural change over time is greatly needed.

    A Cold Target Recoil Ion Momentum Spectroscopy (COLTRIMS) apparatus has been constructed and operated cooperatively by the Atomic and Molecular Physics Laboratory in the Physics Department at the Hashemite University, Jordan, and the Atomic and Molecular Physics Group at the 4.75 MeV Van de Graaff Accelerator Facility at the University of Jordan. This COLTRIMS imaging system allows the investigation of the dynamics of various ion impact induced atomic and molecular interactions and fragmentations. The performance of the COLTRIMS system was tested by carrying out preliminary studies of two collision systems. In the first study, electron capture processes in the He2+-Ne collision system at 0.25 and 1.0 MeV impact energies were investigated. Significant simultaneous electron capture and target excitation has been observed for the 0.25 MeV as opposed to the 1.0 MeV impact energy. In the other study, projectile single electron loss and simultaneous single target ionization in the O+-He collision system was studied at three different projectile impact energies: 0.6, 1.45 and 2 MeV. Enhancement of the electron-electron contribution to projectile electron loss with increasing collision energy has been observed.

    Objectives. To estimate the survival rate of colorectal cancer (CRC) and determine its predictors among Jordanian patients who were diagnosed in the period of 2005–2010. Methods. This study was based on Jordan cancer registry. All CRC cases that were registered in cancer registry during 2005–2010 were analyzed using the survival analysis. The last date for follow-up was 1st Oct 2016. Results. A total of 3005 patients with CRC were registered during 2005–2010. The overall 5-year and 10-year survival rates for patients with CRC were 58.2% and 51.8%, respectively. The 5-year survival rate decreased significantly from 60.4% for the age <50 years to 49.3% for the age ≥70 years (p < 0.005). The 5-year survival rate was 72.1% for the localized stage, 53.8% for the regional stage, and 22.6% for the distant metastasis. In the multivariate analysis, the only factors that were significantly associated with survival were age, grade, stage, and location of tumor. Conclusions. The overall 5-year and ten-year survival rates for CRC were 58.2% and 51.8%, respectively. Increased age, poor differentiation, advanced cancer stage, and right-sided cancers were associated with lower survival rates. Screening strategies are needed for early detection of colon adenomas and colorectal cancer in Jordan. PMID:28458690

    Objectives: To compare clinical, anthropometric, and laboratory characteristics in diabetes type 2 patients of 2 genetically-distinct ethnicities living in Jordan, Arabs and Circassians/Chechens. Methods: This cross sectional ethnic comparison study was conducted in King Abdullah University Hospital, Irbid and The National Center for Diabetes, Endocrinology, and Genetics, Amman, Jordan between June 2013 and February 2014. A sample of 347 (237 Arab and 110 Circassian/Chechen) people living with diabetes were included in the study. Data were collected through direct interviews with the participants. Clinical data were collected using a questionnaire and anthropometric measurements. Laboratory data were extracted from the patients’ medical records. Results: More Arabs with diabetes had hypertension as a comorbidity than Circassians/Chechens with diabetes. Arabs living with diabetes were generally more obese, whereas Circassians/Chechens living with diabetes had worse lipid control. Arabs with diabetes had higher means of glycated haemoglobin (HbA1c) and fasting blood sugar, and more Arabs with diabetes had unsatisfactory glycemic control (60.6%) than Circassians/Chechens with diabetes (38.2%) (HbA1c ≥7.0%). Most participants (88.8%) had at least one lipid abnormality (dyslipidemia). Conclusion: Multiple discrepancies among the 2 ethnic diabetic populations were found. New diabetes management recommendations and policies should be used when treating people living with diabetes of those ethnicities, particularly in areas of glycemic control, lipid control, and obesity.

    Hepatitis A virus (HAV) has emerged as an important public health problem in many countries of the Middle East region and Jordan is no exception. From January 1991 to December 2001, a total of 1015 patients were diagnosed at Al-Battikhi Medical Laboratories. Samples were collected at seventeen private laboratories distributed throughout areas of the Governorate of Amman (capital of Jordan). A significant variation (P=0.03) was obtained between number of HAV cases and year. Seasonal variation in HAV cases was seen throughout the study period with maximal rates in the spring and summer months (P<0.001). The highest incidence rate (9.6/100,000 population) was detected in the year 1993 and the lowest incidence rate (1.1/100,000 population) was found in the year 2001. There was a significant difference (P<0.0001) between number of HAV cases and age group. The highest number of cases 166 (16.4%) was reported for age group 5-14 years and the lowest number of cases 18 (0.02%). Male to female ratio was 1.25: 1. There was no significant sex variation (P=0.28). A significant variation (P=0.006) was observed between number of HAV cases and districts. The present results suggested a link between the age groups, year, month and occurrence of HAV infection. Male to female ratio indicates no significant sex variation.

    Perceived barriers to engaging in exercise in people with Parkinson's disease (PD) are becoming more defined in countries such as the UK and the US. This, however, may vary by culture and environment. This study aimed to explore the perceptions of exercise and barriers that may affect participation in people with PD from Jordan. Two focus groups and seven individual interviews were conducted with people with PD. Additionally, individual interviews were conducted with two neurologists. Conversations were digitally recorded and transcribed. Transcripts were analyzed using thematic analysis and validated via researcher triangulation and peer checking. Most of the PD participants lacked previous participation in any disease-specific exercises. Several barriers were perceived by PD participants for such lack of participation. Barriers included difficulty of diagnosis, lack of informational support provided by neurologists, lack of referral to physiotherapy services, disease-specific issues, and setting-related issues. Neurologists indicated a number of barriers in counseling their PD patients on exercise including lack of time and lack of health system resources. Motivators to participate in future exercise included outcome expectations and family support. Findings of the study shed light into large areas of unmet needs of supporting exercise and physiotherapy for people with PD in developing countries as per Jordan. For better patient outcomes, findings of the study suggest that it is crucial to raise awareness among all PD-related stakeholders on the benefits of early referrals to physiotherapy and early engagement in exercise programs.

    SYNOPSIS Objective The present study examined mean level similarities and differences as well as correlations between mothers’ and fathers’ attributions regarding successes and failures in caregiving situations and progressive versus authoritarian attitudes in Jordan. Design Interviews were conducted with both mothers and fathers in 112 families. Results There were no significant main effects of gender on any of the constructs of interest. Mothers and fathers reported similar levels of attributions regarding uncontrollable success, adult-controlled failure, and child-controlled failure in the same family. Regarding attitudes, mothers and fathers reported greater progressive attitudes than authoritarian attitudes. Large, significant correlations were found for concordance between parents in the same family on all seven attributions and attitudes examined; all remained significant after controlling for parents’ age, education, and possible social desirability bias. Significant positive correlations were found for mothers’ and fathers’ attributions regarding uncontrollable success, adult-controlled failure, child-controlled failure, perceived control over failure, progressive attitudes, authoritarian attitudes, and modernity of attitudes. Conclusions This study concluded that in Jordan mothers and fathers hold similar levels of attributions and attitudes. PMID:21927587

    Job stress is common in health care professionals in the west. Less is known about its prevalence in Middle Eastern countries. To determine job stress, its sources and its effect on health care professionals in northern Jordan. A simple random sample of 101 physician specialists, 126 dentists, 52 general practitioners and 123 pharmacists in northern Jordan completed a socio-demographic questionnaire, the General Health Questionnaire, and addressed structured questions about job stress. Descriptive statistics and multivariate analyses were used to describe and compare participants, and a binary logistic regression was used to identify factors associated with stress and reported health problems. Of the 402 health care professionals, 27% reported high levels of stress. Prevalence was highest among general practitioners (33%), then dentists (30%) and pharmacists (25%). The lowest stress was among physician specialists (12%). Factors associated with the highest stress were being a general practitioner, being a woman and having long working hours. Dealing with uncooperative patients and heavy workloads were additional stressors. The most frequent problems associated with high stress were irritability (58%), consuming more arousal drinks (e.g. coffee, cola) (56%), difficulty concentrating (51%), headaches (63%), chronic back pain (48%) and common colds (47%). Compared to physician specialists, general practitioners, dentists and pharmacists were significantly more stressed. Reported stress was associated with job title, being a woman and long working hours. Also uncooperative patients and heavy workloads were significant problems. Being irritable and having headaches and common colds were the most frequent health issues.

    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. © 2015 Wiley Periodicals, Inc.

    Cancer is a major health problem facing the entire world, and Jordan is no exception. However, patterns of cancer incidence and cancer burden in Jordan have never been explored thoroughly, and the aim of this study was to close this knowledge gap. The study was based on data obtained from the Jordan cancer registry from 1996 to 2009. All cancer cases that were diagnosed during the study period were registered and included in this study. A total of 51,626 cases were registered in Jordan during the 14- year period. The incidence rate showed no significant increase in males (percent change PC 6.8%), while in females a marked increase was observed (PC 14.8%). The major cancer sites for males were bronchus and lung, colorectal, bladder, leukemia and prostate. In females, the leading cancer sites were breast, colorectal, leukemia, thyroid and NHL. Compared to other countries in the region, Jordan has comparable rates. On the other hand the rates of cancer are markedly lower in Jordan compared to more industrialized countries such as the US and Europe. There was an overall increase in the incidence of cancer in Jordan, especially among females, which stresses the need for programs to raise awareness on the importance of early diagnosis and preventive life style measures.

    The vertical distribution of net zooplankton in head-water of Krasnoyarsk hydroelectric power station and its horizontal distribution in the tail-water were studied during two years in winter and summer seasons. In order to distinguish living and dead individuals the special staining was used. It was revealed that on average 77% of living plankton pass through high-head dam with deep water scoop to the tailwater. While passing through dam aggregates some individuals of the reservoir plankton are traumatized and die, that results in some increase of portion of dead individuals in the tail water near dam (from 3 to 6%). Alive zooplankton passed through the dam aggregates is eliminated under the Upper Yenisei highly turbulent conditions. There is approximately 10% of it in 32 km from the dam if compare with biomass in 20-40 m layer of reservoir, the portion of dead increases to 11%. The biomass of zooplankton suspended in the water column of the tail-water sometimes increases (till > 1 g/m3) due to large Copepoda Heteroscope borealis, which inhabits near-bottom and near-shore river zones and can be found in the central part of the river during reproductive period. Limnetic zooplankton from the reservoir cannot be considered as important food for planktivores in the tail-water.

    The Northwest Power Planning Council's 1987 Columbia River Fish and Wildlife Program authorizes the development of artificial production facilities to raise chinook salmon and steelhead for enhancement in the Hood, Umatilla, Walla Walla, Grande Ronde and Imnaha rivers and elsewhere. On February 26, 1991 the Council agreed to disaggregate Hood River from the Northeast Oregon Hatchery Project, and instead, link the Hood River Master Plan (now the Hood River Production Plan) to the Pelton Ladder Project (Pelton Ladder Master Plan 1991).

    A cost study is described which compared the economics of four dry/wet cooling systems to use at the existing Raft River Geothermal Plant. The results apply only at this site and should not be generalized without due consideration of the complete geothermal cycle. These systems are: the Binary Cooling Tower, evaporative condenser, Combin-aire, and a metal fin-tube dry cooling tower with deluge augmentation. The systems were evaluated using cooled, treated geothermal fluid instead of ground or surface water in the cooling loops. All comparisons were performed on the basis of a common plant site - the Raft River 5 MWe geothermal plant in Idaho. The Binary Cooling Tower and the Combin-aire cooling system were designed assuming the use of the isobutane/water surface condenser currently installed at the Raft River Plant. The other two systems had the isobutane ducted to the evaporative condensers. Capital credit was not given to the system employing the direct condensing process. The cost of the systems were estimated from designs provided by the vendors. The levelized energy cost range for each cooling system is listed below. The levelized energy cost reflects the incremental cost of the cooling system for the life of the plant. The estimates are presented in 1981 dollars.

    An aerial radiological survey was conducted over the Oyster Creek Nuclear Power Plant in Forked River, New Jersey, during the period September 18 through September 24, 1992. The survey was conducted at an altitude of 150 feet (46 meters) over a 26-square-mile (67-square-kilometer) area centered on the power station. The purpose of the survey was to document the terrestrial gamma radiation environment of the Oyster Creek Nuclear Power plant and surrounding area. The results of the aerial survey are reported as inferred gamma radiation exposure rates at 1 meter above ground level in the form of a contour map. Outside the plant boundary, exposure rates were found to vary between 4 and 10 microroentgens per hour and were attributed to naturally-occurring uranium, thorium, and radioactive potassium gamma emitters. The aerial data were compared to ground-based benchmark exposure rate measurements and radionuclide assays of soil samples obtained within the survey boundary. The ground-based measurements were found to be in good agreement with those inferred from the aerial measuring system. A previous survey of the power plant was conducted in August 1969 during its initial startup phase. Exposure rates and radioactive isotopes revealed in both surveys were consistent and within normal terrestrial background levels.

    The level of living that any society can attain is a direct function of the use it makes of all kinds of raw materials (soil, water, metals, nonmetals, etc.), all kinds of energy (both animate and inanimate), and all kinds of human ingenuity; and is an inverse function of the size of the population that must share the collective product. The relation between raw materials, energy and ingenuity is such that use of a large amount of one may offset the need for large amounts of others. The most vital raw materials are water, soil, and construction materials, for these are needed in large quantities and are hard to import. Metals, chemicals, and inanimate energy are necessary for industrialization. The more of these minerals a nation possess, the better, but not nation can hope to be self-sufficient in all of the m and therefore must trade for some essential materials. Jordan’s natural resources have been little explored. The grantitc-metamorphic terrane in the southeastern part of the Kingdom could contain deposits of tungsten, rare earths, feldspar, mica, fluorite etc. and the sedimentary terrane over much of the rest of the county is favorable for the occurrence of oil. Even if none of these minerals is found, however, Jordan’s other mineral resource, if fully explored and developed in the light of modern technology, will support a far higher level of living than her people now enjoy. Very likely she can increase her rainfall by about 10 percent by cloud seeding, and she undeveloped supplies in both surface and ground water that are sufficient to nearly double her usable water supply. Even if she does not have oil or have it in large quantities, she can buy it cheaply from neighboring counties, and in addition has undeveloped sources of hydroelectric power, large reserves of bituminous limestone, large reserves of nuclear power as uranium in phosphate rock, and can use solar and wind power for special purposes. Her large supplies of construction, fertilizer, and

    Increasing population levels and demand for water have led to a global water shortage, with more than one billion people unable to access safe drinking water. The Middle East is particularly vulnerable to water stress because of its dense population, variable climate and vulnerable groundwater resources. In Jordan, for example, if current trends in population continue, the water per capita will halve-putting the country in the category of having an absolute water shortage. This opening paper summarizes the climate and hydrology of Jordan and Israel, describes how water is managed at a national level in Jordan and reflects briefly on the broader international context.

  3. Characterization of ground-water discharge from bedrock aquifers to the Mississippi and Minnesota Rivers at three areas, Minneapolis-St. Paul area, Minnesota

    1994-01-01

    The hydrogeology at three areas along the Mississippi and Minnesota Rivers in the Minneapolis-St. Paul area were studied to characterize ground-water discharge from bedrock aquifers to the two rivers. Along the Mississippi River between Fridley and Brooklyn Center, a buried valley underlying the Mississippi River cuts through the overlying terrace deposits and glacial-drift deposits into two underlying bedrock hydro- geologic units: the St Peter aquifer, and a rubble zone between the St. Peter and Prairie du Chien-Jordan aquifers. Shallow ground-water flow in the near-surface gray and upper red tills and sand and gravel outwash aquifer discharges to springs along the edge of the river. Ground water flowing through the rubble zone and upper part of the Prairie du Chien-Jordan aquifer probably discharges through alluvial deposits to the river. In study area 2, along the Minnesota River between Eagan and Bloomington, almost 200 feet of post-glacial alluvium, glaciofluvial sand and gravel, Pleistocene lake deposits, and peat fill a bedrock valley under the present-day Minnesota River. As much as 40 feet of post-glacial peat, silty clay, clay, and muck lie near the river-valley walls. Confining units beneath the river channel impede the discharge of ground water from the underlying Prairie du Chien-Jordan aquifer to the river. Ground water discharges to wetlands, lakes, and springs along both the north and south side of the river. Along the Mississippi River at Minneapolis about 5 miles upstream of the confluence of the Minnesota and Mississippi Rivers, the Mississippi River lies in a post-glacial valley cut through thin glacial drift into the St. Peter aquifer. Beneath the river, ground water flows from the St. Peter aquifer through the overlying post-glacial ailuvium to the Mississippi River. No confining unit separates the St. Peter aquifer and the river.

    This Hydrologic Atlas is one of a series describing the 39 watersheds in Minnesota. The Root River watershed includes Houston, Winona, and parts of the surrounding counties. The 2 ,570 square miles in the watershed varies from gently rolling prairie in the west to an area of plateaus separated by valleys deeply incised into bedrock in the north and east. The average annual water budget for 30 years shows 29.5 inches of precipitation, 7.2 inches of surface runoff, and 22.3 inches of evapotranspiration. Water use in millions of gallons for 1970 was established at 7,310 of ground water and 6,700 of surface water. Domestic supplies accounted for less than one fourth and thermoelectric power for about one half of the total use. All 33 municipalities use ground water from bedrock aquifers, and 21 of those obtain at least part of their supply from the Prairie du Chien-Jordan aquifer. Many private domestic wells are completed in a shallow limestone aquifer. The ground-water system is recharged primarily by infiltrating precipitation in upland areas Ground-water movement is indicated by water-table and potentiometric maps and section diagrams. Water from bedrock and glacial aquifers generally is of acceptable quality for domestic use, dissolved solids generally less than 400 mg/liter very hard , and locally high iron content. The Mount Simon-Red clastics aquifer is locally saline. Runoff is greatest during the spring when snowmelt occurs and the soils are generally saturated.

    Flood warning systems typically rely on forecasts from national meteorological services and in-situ observations from hydrological gauging stations. This capacity is not equally developed in flood-prone developing countries. Low-cost satellite monitoring systems and global flood forecasting systems can be an alternative source of information for national flood authorities. The Global Flood Awareness System (GloFAS) has been develop jointly with the European Centre for Medium-Range Weather Forecast (ECMWF) and the Joint Research Centre, and it is running quasi operational now since June 2011. The system couples state-of-the art weather forecasts with a hydrological model driven at a continental scale. The system provides downstream countries with information on upstream river conditions as well as continental and global overviews. In its test phase, this global forecast system provides probabilities for large transnational river flooding at the global scale up to 30 days in advance. It has shown its real-life potential for the first time during the flood in Southeast Asia in 2011, and more recently during the floods in Australia in March 2012, India (Assam, September-October 2012) and Chad Floods (August-October 2012).The Joint Research Centre is working on further research and development, rigorous testing and adaptations of the system to create an operational tool for decision makers, including national and regional water authorities, water resource managers, hydropower companies, civil protection and first line responders, and international humanitarian aid organizations. Currently efforts are being made to link GloFAS to the Global Flood Detection System (GFDS). GFDS is a Space-based river gauging and flood monitoring system using passive microwave remote sensing which was developed by a collaboration between the JRC and Dartmouth Flood Observatory. GFDS provides flood alerts based on daily water surface change measurements from space. Alerts are shown on a

    The influx of Syrian refugees into Jordan presents an immense burden to the Jordanian health system. Changing lifestyles and aging populations are shifting the global disease burden towards increased non-infectious diseases including chronic conditions, co-morbidities, and injuries which are more complicated and costly to manage. The strain placed on health systems threatens the ability to ensure the health needs of both refugees and host country populations are adequately addressed. In light of the increasing challenges facing host governments and humanitarian actors to meet health needs of Syrian refugees and affected host communities, this study was undertaken to assess utilization of health services among Syrian refugees in non-camp settings. A survey of Syrian refugees in Jordan was undertaken in June 2014 to characterize health seeking behaviors and issues related to accessing care. A cluster design with probability proportional to size sampling was used to attain a nationally representative sample of 1550 non-camp Syrian refugee households. Differences in household characteristics by geographic region, facility type, and sector utilized were examined using chi-square and t-test methods. Care-seeking was high with 86.1 % of households reporting an adult sought medical care the last time it was needed. Approximately half (51.5 %) of services were sought from public sector facilities, 38.7 % in private facilities, and 9.8 % in charity/NGO facilities. Among adult care seekers, 87.4 % were prescribed medication during the most recent visit, 89.8 % of which obtained the medication. Overall, 51.8 % of households reported out-of-pocket expenditures for the consultation or medications at the most recent visit (mean US$39.9, median US$4.2). Despite high levels of care-seeking, cost was an important barrier to health service access for Syrian refugees in Jordan. The cessation of free access to health care since the time of the survey is likely to have worsened

It explores the character of the population that arrived en masse in Jordan and whether their arrival burdened or benefitted that country.... The involuntary migration compounded other effects of the Gulf crisis on Jordan and exacerbated the country's already serious economic problems. Integration of the returnees was painful. But contrary to initial expectations, the mass arrival did not result in unmitigated disaster and may have contributed to an economic recovery in Jordan, suggesting that there may be potentially beneficial windfall effects of sudden population influxes, even when they are involuntary and disorderly."

    To estimate the price elasticity of cigarette demand for university students aged 18-24 years in Jordan. Questions from the Global Adult Tobacco Survey were adapted and administered to students from 10 public universities in Jordan in 2014. A two-part econometric model of cigarette demand was estimated. Nearly one-third of university students in Jordan smoke, purchasing 33.2 packs per month and paying 1.70 Jordanian dinars on average (US$2.40) for a pack of 20 cigarettes. The price elasticity of cigarette demand was estimated to be -1.15. Higher taxes may be particularly effective in reducing smoking among University students in Jordan.

    A vertical-fluted-tube condenser was designed, fabricated, and tested with isobutane as the shell-side working fluid in a binary prototype power plant at the Raft River Geothermal Test Site. After shakedown and contamination removal operations were completed, the four-pass water-cooled unit (with 102 outside-fluted Admiralty tubes) achieved performance predictions while operating with the plant surface evaporator on-line. A sample comparison shows that use of this enhanced condenser concept offers the potential for a reduction of about 65% from the size suggested by corresponding designs using conventional horizontal-smooth-tube concepts. Subsequent substitution of a direct-contact evaporator for the surface evaporator brought drastic reductions in system performance, the apparent consequence of high concentrations of noncondensible gases introduced by the brine/working-fluid interaction.

    We investigated the particle size distribution of radiocesium in riverbed sediments after the Fukushima Daiichi Nuclear Power Plant accident. Riverbed sediments were collected in the Abukuma River system in Fukushima and Miyagi Prefectures. The collected sediments were separated into 11 fractions, ranging from granular size (>2000 μm) to clay size (<2 μm) fractions. Cesium-137 concentrations were higher in the smaller particle size fractions, possibly reflecting specific surface areas and the mineralogy, in particular the clay mineral content. A gap in (137)Cs concentration was observed between the silt size and sand size fractions of riverbed sediments at downstream sites, whereas riverbed sediments at an upstream site did not show such a concentration gap. It is likely that selective transport of small particles in suspended state from upstream areas resulted in an accumulation of radiocesium in downstream areas.

    This study evaluates the Better Parenting Programme (BPP), which has been implemented nationally in Jordan to enhance parents' knowledge, attitudes, and behaviours related to caring for young children. Participants (N = 337, 94% female) were randomly assigned to an experimental group or a control group. The experimental group participated in the BPP; the control group did not. Before and after the BPP, all participants completed questionnaires to assess their knowledge regarding key areas of child development, activities with their children, discipline practices, and perceptions regarding behaviours that constitute child abuse and neglect. Over time, participants in the experimental group (but not the control group) improved on parenting knowledge, spending time playing and reading books with their children, using more explanations during the course of disciplining their child, and accurately perceiving behaviours that constitute child neglect. Results suggest modest beneficial effects of participation in the Better Parenting Programme.

    Using a result of H. Hanche-Olsen, we show that (subject to fairly natural constraints on what constitutes a system, and on what constitutes a composite system), orthodox finite-dimensional complex quantum mechanics with superselection rules is the only non-signaling probabilistic theory in which (i) individual systems are Jordan algebras (equivalently, their cones of unnormalized states are homogeneous and self-dual), (ii) composites are locally tomographic (meaning that states are determined by the joint probabilities they assign to measurement outcomes on the component systems) and (iii) at least one system has the structure of a qubit. Using this result, we also characterize finite dimensional quantum theory among probabilistic theories having the structure of a dagger-monoidal category.

    The Koecher-Vinberg theorem tells us that formally real Jordan algebras are equivalent to finite-dimensional order-unit spaces having homogeneous, self-dual cones. Recent work by the authors and others has identified various conditions that imply the homogeneity and self-duality of the cones generated by the states and effects of a generalized probabilistic model. This talk highlights two results: one shows that a certain package of conditions, relating the the symmetries of a system and the existence of certain correlations between systems, is sufficient to ground a model's self-duality. Another shows that any dagger-monoidal category of homogeneous, self-dual probabilistic theories having locally tomographic composites and containing a system with the structure of a qubit, must consist of self-adjoint parts of complex matrix algebras --- must, in other words, be a standard finite-dimensional quantum theory.

    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.

    The study aimed to assess adolescent patterns of eating habits, determine factors influencing these patterns, and identify male and female differences related to eating habits. Using a cross-sectional study approach, a sample of adolescents ( N = 423) in randomly selected clusters chosen from government and private schools in the south of Jordan completed self-administered questionnaires relating to socio-demographic data and personal eating habits. Results showed that parents, peers, and mass media are contributing factors, with peer pressure likely outweighing parental guidance. Males were more likely to be influenced by peers than females, whereas females were more likely to be influenced by media-based advertising. Lower body mass indices correlate with eating breakfast, which a majority of adolescents reported they do not do. Interventions targeted toward improving eating and active behaviors should involve peers as well as parents.

    1983-02-01

    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.

    In the present study, we evaluated the antimicrobial activity of 16 Jordanian medicinal plant extracts against four reference bacteria; Staphylococcus aureus, Enterobacter faecalis, Escherichia coli, and Salmonella typhi. For that purpose, whole plants were extracted and antimicrobial susceptibility testing and minimum inhibitory concentration (MIC) were determined. Ethanolic extracts of most medicinal plants exerted a dose-dependent cytotoxiciy against different reference bacteria. Origanum syriaca, Varthemia iphionoides, Psidium guajava, Sarcopoterium spinosa plant extracts were most active against S. aureus (MIC; 70 μg/mL), E. faecalis (MIC; 130 μg/mL), E. coli (MIC; 153 μg/mL), and S. typhi (MIC; 110 μg/mL), respectively. Results indicate that medicinal plants grown in Jordan might be a valuable source of starting materials for the extraction and/or isolation of new antibacterial agents.

    Little is known about the risk factors of human brucellosis in Jordan. A case-control study was conducted involving 56 Jordanians who had been treated for brucellosis and at least 3 matched controls for each case (n = 247). Matching was for sex, age, locality (the same village) and socioeconomic standard. Univariate and multivariate logistic regression analyses were used. In all, 17 risk factors were examined related to: contact with various livestock, milk and milk product consumption, drinking-water treatment and disease awareness. Most variables were associated with brucellosis in the univariate analysis but the final logistic model included only 4: milking sheep and goats (OR 3.5), consumption of raw feta cheese made from sheep and goat milk (OR 2.8) and consumption of cows' milk (OR 0.4) and boiled feta cheese (OR 0.4). Small ruminant farmers need to be trained in safer milking practices and feta cheese making procedures.

    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".

    Tom Jordan has made a fundamental contribution to our understanding of the grandest- scale problems of the earth's tectonics by stimulating our consciousness about the deeper part of continents. He has stimulated not only seismologists and other geophysicists but also geochemists by introducing the idea of the continental tectosphere.This idea, of which the origin can be traced to his Ph.D. thesis, has given a unity to his impressive body of work accomplished over the past decade employing a variety of approaches ranging from mathematical to geochemical. It is rare that a scientist at such an early stage of his career conceives an original working hypothesis which then keeps him productive, diversified, and developing consistently over a decade.

    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.

    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

    Adverse drug reactions (ADRs) represent a major health care problem. To identify the most common ADRs, drugs implicated in ADRs, and to assess their causality, severity, preventability and risk factors predisposing to reported ADRs in Jordan. Al-Karak teaching hospital, southern of Jordan. Method A cross sectional observational study was carried out for 11 months from January to November 2013. Suspected ADRs were recorded in ADRs report forms and analyzed for causality, severity, and preventability. Most common ADRs, drugs involved in these ADRs, causality, severity, and preventability of suspected ADRs. A total of 64 reports were received. Some patients suffered more than one ADR. The total number of ADRs identified was 108. Forty one drugs were involved in causing these ADRs. About 2/3 of adverse reactions (73.4 %) did not cause admission to the hospital, whereas 26.6 % of the ADRs resulted in admission. Majority of the ADRs were type A (62.5 %). Most of ADRs (92.2 %) were assessed as probable. Nearly, 65.6 % of ADRs were categorized as mild. Majority of ADRs were assessed as "not preventable" (75 %). The most common classes of drugs involved in ADRs were antibiotics, analgesics, vaccines and antiepileptics. The most commonly identified ADRs were abdominal pain, skin rash, shortness of breath, fever, upper gastrointestinal bleeding and vomiting. Risk factors contributed to ADRs were age and polypharmacy. Jordanian healthcare providers should be aware of the importance of detecting and reporting ADRs, in order to prevent and reduce the incidence of ADRs. Awareness of risk factors predisposing to ADRs may help in identifying patients with higher risk and therefore reducing the risk of these ADRs and improving patient outcome.

    To estimate the prevalence of blindness, visual impairment, diabetes, and diabetic retinopathy in north Jordan (Irbid) using the rapid assessment of avoidable blindness and diabetic retinopathy methodology. A multistage cluster random sampling technique was used to select participants for this survey. A total of 108 clusters were selected using probability proportional to size method while subjects within the clusters were selected using compact segment method. Survey teams moved from house to house in selected segments examining residents 50 years and older until 35 participants were recruited. All eligible people underwent a standardized examination protocol, which included ophthalmic examination and random blood sugar test using digital glucometers (Accu-Chek) in their homes. Diabetic retinopathy among diabetic patients was assessed through dilated fundus examination. A total of 3638 out of the 3780 eligible participants were examined. Age- and sex-adjusted prevalence of blindness, severe visual impairment, and visual impairment with available correction were 1.33% (95% confidence interval [CI] 0.87-1.73), 1.82% (95% CI 1.35-2.25), and 9.49% (95% CI 8.26-10.74), respectively, all higher in women. Untreated cataract and diabetic retinopathy were the major causes of blindness, accounting for 46.7% and 33.2% of total blindness cases, respectively. Glaucoma was the third major cause, accounting for 8.9% of cases. The prevalence of diabetes mellitus was 28.6% (95% CI 26.9-30.3) among the study population and higher in women. The prevalence of any retinopathy among diabetic patients was 48.4%. Cataract and diabetic retinopathy are the 2 major causes of blindness and visual impairment in northern Jordan. For both conditions, women are primarily affected, suggesting possible limitations to access to services. A diabetic retinopathy screening program needs to proactively create sex-sensitive awareness and provide easily accessible screening services with prompt treatment.

    Human metapneumovirus (HMPV) has recently been identified as an important cause of acute respiratory infections (ARI) in children worldwide. However, there is little systematic data on its frequency and importance as a cause of ARI in the Middle East. We conducted a viral surveillance study in children <5 years of age admitted with respiratory symptoms and/or fever at two major tertiary care hospitals in Amman, Jordan from 1/18-3/29/07. Nose and throat swabs were collected and tested for HMPV and other respiratory viruses by real-time RT-PCR. A total of 743 subjects were enrolled. Forty-four (6%) subjects were positive for HMPV, 467 (64%) were positive for RSV and 13 (1.3%) had co-infection with both HMPV and RSV. The frequency of HMPV in January, February, and March was4.1%, 3.0%, and 11.9% respectively. Clinical features associated with HMPV infection were similar to those of other respiratory viruses, except children with HMPV were more likely to present with fever than children not infected with HMPV. Children with HMPV and RSV co-infection were administered supplemental oxygen and were admitted to the ICU more frequently than children infected with HMPV alone or RSV alone, though these differences did not reach statistical significance. We conclude that HMPV is an important cause of acute respiratory infections in children in Amman, Jordan. Longer surveillance studies are needed to better understand the seasonal epidemiology of HMPV and to assess if co-infection with HMPV and RSV leads to more severe illness. PMID:20419816

    Current pain assessment and management in neonates need to be fully described before neonatal pain care can be optimized. This study's purpose was to report neonatal nurses' knowledge, existing pain assessment practice, and pharmacological pain management of neonates in Jordan. A cross-sectional descriptive study was conducted. Eighteen neonatal intensive care units in Jordan were included in the study. One hundred eighty-four neonatal nurses participated. Questionnaires were distributed by and returned to the neonatal intensive care units' managers between June and August 2014. Descriptive and inferential statistics were used to present study results. Of 240 questionnaires distributed, 184 useable responses were returned. Nurses' knowledge regarding neonates' neurological development, nociception, and need for neonatal pain management was suboptimal. The analgesics most commonly used to treat neonatal pain were acetaminophen (52%) and lidocaine (45%). Benzodiazepines, phenobarbitone, and muscles relaxants were also used. Most nurses (54%-97%) reported that pain emanating from most painful procedures was never or rarely treated. Circumcision, lumbar punctures, and chest tube insertion were assigned the highest pain scores (≥9), but were rarely accompanied by analgesia. Pain assessment scales were more likely to be used, and procedural pain was more likely to be treated, in private hospitals than public hospitals. Neonates who require special care still suffer unnecessary pain that could be avoided and managed by following best practice recommendations. Disparities between developed and developing countries in quality of neonatal pain care appear to exist. Resources for education and routine care are needed to address these discrepancies.

    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

    The Iraq conflict resulted in the largest displacement in the Middle East in recent history, and provision of health services to the displaced population presents a critical challenge. With an increase in the number of people affected by complex emergencies and the number of people displaced in urban settings, the international community must adapt intervention strategies to meet the specific demands and contexts of this population. The study aimed to provide information on food security and livelihoods for Iraqi refugees in Syria and Jordan to inform humanitarian assistance planning. National cross-sectional cluster sample surveys of displaced Iraqi populations displaced were conducted in Jordan (October 2008) and Syria (March 2009). Clusters of ten households were randomly selected using probability-based sampling; a total of 1200 and 813 Iraqi households in Jordan and Syria, respectively, were interviewed about food security and receipt of humanitarian assistance. In Syria, 60% of households reported the household food situation had declined since the arrival period as compared to 46% in Jordan. Food aid receipt was reported by 18.0% of households in Jordan and 90.3% of households in Syria. In Jordan, 10.2% of households received cash assistance and in Syria 25.3% of households received cash assistance. In Jordan, cash assistance was associated with low socioeconomic status, large household size, and UNHCR registration. In Syria, female headed households, Damascus residents, families with children, and those registered with UNHCR were more likely to receive cash assistance. Food insecurity remains a concern among displaced Iraqi households in both Jordan and Syria. Improved targeting of both food and cash assistance and the expansion of cash-based programs could lead to a more effective use of funds and facilitate the implementation of assistance programs that are sustainable in the context of declining funding availability.

    A novel general approach to round-off error analysis using the error complexity concepts is described. This is applied to the analysis of the Gaussian Elimination and Gauss-Jordan scheme for solving linear equations. The results show that the two algorithms are equivalent in terms of our error complexity measures. Thus the inherently parallel Gauss-Jordan scheme can be implemented with confidence if parallel computers are available.

    The Lower Yarmouk Gorge (LYG) lies on the eastern margin of the lower Jordan Rift Valley (JRV), bounded to the south by the Ajlun and to the north by the Golan Heights. It allows the outflow of the Yarmouk drainage basin and flow into the Jordan River, a few kilometers south of Lake Tiberias. The main aquifer system of the LYG is built mostly of Cretaceous sandstones and carbonates confined by Maastrichtian aquiclude. Fissures allow hydraulic connections between the major water-bearing formations from Quaternary to Upper Cretaceous age. It is supposed that the gorge acts as the mixing zone of two crossing flow pathways: N-S from the Hermon Mountains and from the Ajlun Dome, and E-W from Jebel al Arab Mountain in Syria (also known as Huran Plateau or Yarmouk drainage basin). As a result, several springs can be found within the gorge. These are characterized by widespread temperatures (20 - 60 °C) which indicate that, beside the complex regional flow, also ascending thermal waters control the hydrologic behavior of the LYG. Previous simulations based on a conceptual simplified 3D model (Magri et al., 2016) showed that crossing flow paths result from the coexistence of convection, that can develop for example along NE-SW oriented faults within the gorge or in permeable aquifers below Maastrichtian aquiclude, and additional flow fields that are induced by the N-S topographic gradients. Here we present the first 3D hydrogeological model of the entire LYG that includes structural features based on actual logs and interpreted seismic lines from both Israeli and Jordanian territories. The model distinguishes seven units from upper Eocene to the Lower Triassic, accounting for major aquifers, aquicludes and deep-cutting faults. Recharges are implemented based on the numerical representation developed by Shentsis (1990) that considers relationships between mean annual rain and topographic elevation. The model reveals that topography-driven N-S and E-W flows strongly control

    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

    Many coal-fired electric generating facilities in the United States are discharging higher loads of Hg, Se, and other chemicals to receiving streams due to the installation of flue gas desulfurization (FGD) air pollution control units. There are regulatory concerns about the potential increased uptake of these bioaccumulative trace elements into food webs. We evaluated the concentrations of As, total Hg (THg), methylmercury (MeHg), and Se in Ohio River fish collected proximal to coal-fired power plants, of which 75% operate FGD systems. Fillet samples (n = 50) from 6 fish species representing 3 trophic levels were analyzed. Geometric mean fillet concentrations of THg (wet wt), MeHg (wet wt), and Se (dry wt) in 3 species were 0.136, 0.1181, and 3.19 mg/kg (sauger); 0.123, 0.1013, and 1.56 mg/kg (channel catfish); and 0.127, 0.0914, and 3.30 mg/kg (hybrid striped bass). For all species analyzed, only 3 fillet samples (6% of total) had MeHg concentrations that exceeded the US Environmental Protection Agency (USEPA) human health criterion (0.3 mg/kg wet wt); all of these were freshwater drum aged ≥ 19 y. None of the samples analyzed exceeded the USEPA proposed muscle and whole body Se thresholds for protection against reproductive effects in freshwater fish. All but 8 fillet samples had a total As concentration less than 1.0 mg/kg dry wt. Mean Se health benefit values (HBVSe ) for all species were ≥ 4, indicating that potential Hg-related health risks associated with consumption of Ohio River fish are likely to be offset by adequate Se concentrations. Overall, we observed no measurable evidence of enhanced trace element bioaccumulation associated with proximity to power plant FGD facilities, however, some enhanced bioaccumulation could have occurred in the wastewater mixing zones. Furthermore, available evidence indicates that, due to hydraulic and physical factors, the main stem Ohio River appears to have low net Hg methylation potential.

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.

    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.

    This paper describes an analytical method for estimation of the economical feasibility of a project for wind energy utilization in Jordan. The method is applied to a windfarm and is based on the wind speed distribution at the site considered and on the financial parameters for the complete plant and its running costs. For this method, equations were derived to calculate the cost of a kWh generated by wind turbines with different characteristics as a function of the capital investment per kW installed capacity. The method was applied to the sites at which Royal Scientific Society performs wind speed measurements, and the results indicate that some of these sites are well suited for cost efficient generation of electricity by wind energy. The results also show that a wind tribine which is designed to have a relatively low rated speed has a wider range of economical operation than a wind turbine with a higher rated speed for the sites investigated assuming that the maximum rated power for all for the wind turbines is held constant.

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

    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 δO18 = -7.0 to -7.26 and δD = -32.2 to -33.28, whereas that of the Jordan Valley of 350 mm/year is highly enriched in isotopes with δO18 = -4.06 and δD = -14.5. The groundwater recharged along the highlands is depleted in isotopes (δO18 = -6, δD = -30), groundwater at the intermediate elevations is enriched (δO18 = -5, δD = -23) and that of the Jordan Valley aquifers containing meteoric water is highly enriched (δO18 -3.8, δD = -18). The deep aquifers in the Jordan Valley foothills are depleted in isotopes (δO18 -18 = -6, δD = -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

    Physical, chemical and biological water quality data from five sites in the Tennessee River, two in Guntersville Reservoir and three in Wheeler Reservoir were correlated with climatological data for three annual cycles. Two of the annual cycles are for the years prior to the Browns Ferry Nuclear Power Plant operations and one is for the first 14 months of Plant operations. A comparison of the results of the annual cycles indicates that two distinct physical conditions in the reservoirs occur, one during the warm months when the reservoirs are at capacity and one during the colder winter months when the reservoirs have been drawn-down for water storage during the rainy months and for weed control. The wide variations of physical and chemical parameters to which the biological organisms are subjected on an annual basis control the biological organisms and their population levels.

    Aquifers dominated by Pleistocene basalts and Jurassic to Cretaceous calcareous rocks feed the Hula basin which is drained by the Jordan River into Lake Kinneret. The sedimentary sequence of Lower-Middle Pleistocene Benot Ya'akov Formation (BYF) exposed by excavations of the 0.78 Ma lake-side site of Gesher Benot Ya'aqov (GBY) consists of six cycles representing ca. 100 ka history of the Hula basin. This study characterizes the types of water sources in the catchment, tests the use of the Strontium (Sr) isotopes in the common extant snail Melanopsis sp. as a tracer for water in its habitat, and uses this tracer in the fossil specimens from GBY to investigate the palaeohydrology of the Hula paleolake during the corresponding period. The Sr isotope composition ((87)Sr/(86)Sr) of extant Melanopsis shells in the Hula catchment range widely (0.7046-0.7079). These analyses define distinct groups of water sources and aquifers, while the Jordan River at the GBY site has values around 0.70685. The values for fossil Melanopsis from GBY vary along stratigraphy; they are highest around 0.70710 in Cycles 1 and 2, decrease to around 0.70685 in Cycle 3, and exhibit upward trending fluctuations in the subsequent cycles to 0.70703 in Cycle 6. This trend reveals the dominance of the Hermon Jurassic aquifer during the earlier, colder periods before the Matuyama-Brunhes Boundary (MBB) and enhanced influence of the Golan basaltic aquifers, in subsequent warmer periods, indicating that the MBB coincides with climate warming as supported by other indicators. Hence, this global geochronological indicator of 0.78 Ma is also potentially a global palaeoclimatic marker. The similarity between the Sr isotope composition of the Jordan River waters and Melanopsis and those from Cycle 3 suggests that the current climate corresponds to that of the warmest period within the record of GBY, clarifying the comparative interpretation of this 100 k.yr. climate record.

    Due to their operational flexibility, hydroelectric dams are ideal candidates to compensate for the intermittency and unpredictability of wind energy production. However, more coordinated use of wind and hydropower resources may exacerbate the impacts dams have on downstream environmental flows, that is, the timing and magnitude of water flows needed to sustain river ecosystems. In this paper, we examine the effects of increased (i.e., 5%, 15%, and 25%) wind market penetration on prices for electricity and reserves, and assess the potential for altered price dynamics to disrupt reservoir release schedules at a hydroelectric dam and cause more variable and unpredictable hourly flow patterns (measured in terms of the Richards-Baker Flashiness (RBF) index). Results show that the greatest potential for wind energy to impact downstream flows occurs at high (∼25%) wind market penetration, when the dam sells more reserves in order to exploit spikes in real-time electricity prices caused by negative wind forecast errors. Nonetheless, compared to the initial impacts of dam construction (and the dam's subsequent operation as a peaking resource under baseline conditions) the marginal effects of any increased wind market penetration on downstream flows are found to be relatively minor.

    Facing the air pollution problems in China, emission control strategies have been implemented within the framework of national Five-Year Plan (FYP). According to the lack of post-assessment studies in the literature, this study assessed the effectiveness of the SO2 emission control policies on power plants after the 11th FYP (2006-2010) by modeling emission control scenarios. The idealized emission control policy (the PS90 scenario with assumption of 90% SO2 emission reduction from power plants) could reduce the SO2 and SO4(2-) concentrations by about 51 and 14%, respectively, over the Yangtze River Delta region. While the actual emission control condition (the P2010 scenario based on the actual emissions from power plants in 2010) demonstrated that the actual reduction benefits were 30% of SO2 and 9% of SO4(2-). On the city scale, the P2010 scenario imposed positive benefits on Shanghai, Nanjing, Nantong, and Hangzhou with SO2 reductions of about 55, 12, 30, and 21%, respectively, while an 11% increase of SO2 concentration was found in Ningbo. The number of days exceeding China's National Ambient Air Quality Standard of Class I daily SO2 concentration was estimated to be 75, 52, 7, 77, and 40 days for Shanghai, Nanjing, Nantong, Ningbo, and Hangzhou under the real SO2 control condition (P2010). The numbers could be decreased by 16, 11, 2, 21, and 11% if the control effect reaches the level of the PS90 scenario. This study serves as a scientific basis to design capable enforcement of emission control strategies in China in the future national plans.

    Use of inhalers requires accurate completion of multiple steps to ensure effective medication delivery. To evaluate the most problematic steps in the use of Diskus and Turbuhaler for pharmacists and patients in Jordon and Australia. With standardized inhaler-technique checklists, we asked community pharmacists to demonstrate the use of Diskus and Turbuhaler. We asked patients with asthma to demonstrate the inhaler (Diskus or Turbuhaler) they were currently using. Forty-two community pharmacists in Jordan, and 31 in Australia, participated. In Jordan, 51 asthma patients demonstrated use of Diskus, and 40 demonstrated use of Turbuhaler. In Australia, 53 asthma patients demonstrated use of Diskus, and 42 demonstrated use of Turbuhaler. The pharmacists in Australia had received inhaler-technique education more recently than those in Jordan (P = .03). With Diskus, few pharmacists in either country demonstrated correct technique for step 3 (exhale to residual volume) or step 4 (exhale away from the device), although there were somewhat fewer errors in Australia than Jordan (16% vs 0% in step 3, P = .007, and 20% vs 0% in step 4, P = .003 via chi-square test). With Turbuhaler there were significant differences between the pharmacists from Australia and Jordan, mainly in step 2 (hold the device upright while loading, 45% vs 2% correct, P < .001). Few of the patients had received inhaler-technique education in the previous year. The patients made errors similar to those of the pharmacists in individual steps with Diskus and Turbuhaler. The essential steps with Diskus were performed correctly more often by the Jordanian patients, and with Turbuhaler by the Australian patients. Despite differences in Jordan's and Australia's health systems, pharmacists from both Australia and Jordan had difficulty with the same Diskus and Turbuhaler steps. In both countries, the errors made by the asthma patients were similar to those made by the pharmacists.

    The interpretation of a deep seismic refraction study in Jordan, performed in May 1984, shows that much of the country is underlain by continental crust, 32-35 km thick, and normal mantle with a velocity of 8.0-8.2 km/s. In the Aqaba region, southwest and central Jordan, east of Wadi Araba, the crustal thickness is of the order of 32-35 km, while in the Amman region it is not less than 35 km. In southeast Jordan the crust thickens to at least 37 km in what is probably the transition to the Arabian Shield type of crust. The boundaries between the upper and lower crust at about 20 km depth and the lower crust and uppermost mantle are probably transition zones. The upper crystalline crust has velocities of 5.8-6.5 km/s while the lower crust has velocities greater than or around 6.65 km/s. While the crystalline basement is exposed in southwest Jordan and is at a depth of 2-2.5 km north of Amman, it is at a depth of not less than 5 km in central Jordan. A comparison of the crustal type and structure of Jordan and the adjacent Dead Sea rift with that of the Black Forest and the Rhine valley yields a striking resemblance. The situation of the Jordan-Dead Sea rift is explained in terms of the continental crust of Arabia rifting in preference to the thin (?oceanic) crust of the Mediterranean Sea.

  12. Molecular pedigree reconstruction and estimation of evolutionary parameters in a wild Atlantic salmon river system with incomplete sampling: a power analysis

    PubMed Central

    2014-01-01

    Background Pedigree reconstruction using genetic analysis provides a useful means to estimate fundamental population biology parameters relating to population demography, trait heritability and individual fitness when combined with other sources of data. However, there remain limitations to pedigree reconstruction in wild populations, particularly in systems where parent-offspring relationships cannot be directly observed, there is incomplete sampling of individuals, or molecular parentage inference relies on low quality DNA from archived material. While much can still be inferred from incomplete or sparse pedigrees, it is crucial to evaluate the quality and power of available genetic information a priori to testing specific biological hypotheses. Here, we used microsatellite markers to reconstruct a multi-generation pedigree of wild Atlantic salmon (Salmo salar L.) using archived scale samples collected with a total trapping system within a river over a 10 year period. Using a simulation-based approach, we determined the optimal microsatellite marker number for accurate parentage assignment, and evaluated the power of the resulting partial pedigree to investigate important evolutionary and quantitative genetic characteristics of salmon in the system. Results We show that at least 20 microsatellites (ave. 12 alleles/locus) are required to maximise parentage assignment and to improve the power to estimate reproductive success and heritability in this study system. We also show that 1.5 fold differences can be detected between groups simulated to have differing reproductive success, and that it is possible to detect moderate heritability values for continuous traits (h2 ~ 0.40) with more than 80% power when using 28 moderately to highly polymorphic markers. Conclusion The methodologies and work flow described provide a robust approach for evaluating archived samples for pedigree-based research, even where only a proportion of the total population is sampled.

  14. Methods to determine pumped irrigation-water withdrawals from the Snake River between Upper Salmon Falls and Swan Falls Dams, Idaho, using electrical power data, 1990-95

    Pumped withdrawals compose most of the irrigation-water diversions from the Snake River between Upper Salmon Falls and Swan Falls Dams in southwestern Idaho. Pumps at 32 sites along the reach lift water as high as 745 feet to irrigate croplands on plateaus north and south of the river. The number of pump sites at which withdrawals are being continuously measured has been steadily decreasing, from 32 in 1990 to 7 in 1998. A cost-effective and accurate means of estimating annual irrigation-water withdrawals at pump sites that are no longer continuously measured was needed. Therefore, the U.S. Geological Survey began a study in 1998, as part of its Water-Use Program, to determine power-consumption coeffi- cients (PCCs) for each pump site so that withdrawals could be estimated by using electrical powerconsumption and total head data. PCC values for each pump site were determined by using withdrawal data that were measured by the U.S. Geological Survey during 1990–92 and 1994–95, energy data reported by Idaho Power Company during the same period, and total head data collected at each site during a field inventory in 1998. Individual average annual withdrawals for the 32 pump sites ranged from 1,120 to 44,480 acre-feet; average PCC values ranged from 103 to 1,248 kilowatthours per acre-foot. During the 1998 field season, power demand, total head, and withdrawal at 18 sites were measured to determine 1998 PCC values. Most of the 1998 PCC values were within 10 percent of the 5-year average, which demonstrates that withdrawals for a site that is no longer continuously measured can be calculated with reasonable accuracy by using the PCC value determined from this study and annual power-consumption data. K-factors, coefficients that describe the amount of energy necessary to lift water, were determined for each pump site by using values of PCC and total head and ranged from 1.11 to 1.89 kilowatthours per acre-foot per foot. Statistical methods were used to define the

    Bovine leukemia virus (BLV) is distributed worldwide. BLV has many effects on the health status and productivity of infected animals and is a potential risk for humans. In this study, we aimed to investigate the presence of and genotype bovine leukemia viruses on Jordanian dairy farms. Nested PCR coupled with RFLP and direct sequencing of a partial fragment of the env gene were carried out. Two BLV genotypes were found, genotypes 1 and 6. These genotypes were identified by nested PCR-RFLP of 444 bp of the env gene by restriction digestion with HaeIII, Bcl I and Pvu II. However, BLV-Jordan-10 seems to represent an entirely new genotype in our phylogenetic analysis. The nucleotide sequence identity between these two Jordanian BLV genotypes (1 and 6) was 96.2 %. The nucleotide sequence identity between Jordanian BLV genotype 1 and other reference BLV genotype 1 strains ranged from 99 % to 99.5 %. The nucleotide sequence similarity of the Jordanian BLV genotype 6 to other BLV genotypes ranged from 90 % to 96.7 %. A neutralizing motif and CD8(+) T-cell epitope were found in the env protein of both Jordanian isolates. In this study, we documented the presence of two BLV genotypes (1 and 6) on Jordanian dairy farms.

    From March 1996 to February 1997, slaughtered-sheeps' heads were examined for the metacestode of Taenia multiceps. Out of 451 sheep heads, only 12 (3%) were infested. All cysts but one were in the age group 0.5-2.5 years old, with prevalence of 10% (11 of 108). Eleven of 12 infested heads were found during the spring and autumn seasons. Out of 95 flocks involved in questionnaire survey unrelated to the abattoir survey, all the farmers reported the existence of the clinical signs known for coenurosis and described it in locally known names and diseases. Twenty-five of them had recent cases that were diagnosed by the veterinarian as coenurosis cases. Each flock reported one or two cases at the time of survey. A variety of clinical signs were reported from these cases (n = 42). These included circling (86%), head pressing (52%), blindness (29%) and paresis (40%). Coenurosis is a sheep-health problem and an important cause of sheep culling in Jordan. Copyright 2002 Elsevier Science B.V.

    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:18180541

    Marls and marly limestone deposits cover most of Northern Jordan, where Amman City and its suburbs are located. These deposits serve as foundations for most buildings and roads as well as fill material for structural back filling, especially road bases and sub-bases. The present study aims at investigating the geotechnical characteristics and mineral composition of the marl units of these deposits through field investigations and laboratory testing. Using X-ray diffraction technique along with chemical analysis, representative samples of marl horizons were tested for mineral composition, and for a set of index and geotechnical properties including: specific gravity, grain size, Atterberg limits, Proctor compaction and shear strength properties. The test results show a positive linear relationship as expected between the clay content and both liquid and plastic limits. The tests results also show an inverse linear relationship between the clay content and the maximum dry density in both standard and modified compaction. This is attributed to the adsorption of water by the clay minerals. The relationship is more prominent in the case of modified compaction test. The results also indicate a similar relationship for the angle of internal friction. No clear correlation between cohesion and clay content was apparent.
