    The aim of this study was to study the effect of a teaching unit on upgrading university-nursing students' knowledge and attitudes about genetic counseling. The study used pre- test, posttest with no control group design. All nursing students (100) who accepted to participate in the study and enrolled in the Maternity and Gynecological-nursing course, during the second semester of the third academic year 1999-2000, at the Faculty of Nursing, Alexandria University, were involved in the study. A self-administered questionnaire sheet was used to assess nursing students' knowledge about genetic counseling, while a 3-point Likert-like scale was used to assess their attitudes towards it. The content of six-hours' teaching unit -about genetic counseling was taught to students by the researchers based on their needs. The study revealed a general lack of knowledge among nursing students regarding basic information about genetic counseling, where poor total score of knowledge was obtained by all of them in the pre-test. In addition, the pre-test revealed that negative attitude was found in about half of the nursing students. The teaching unit had an obvious effect on the nursing students' knowledge and attitudes regarding genetic counseling, as the total score of their knowledge and attitudes had improved after implementation of the teaching unit. Moreover, there was a significant relationship between nursing students' knowledge and attitudes towards genetic counseling before and after implementation of the teaching unit. Therefore, a negative attitude was found with poor total score of knowledge in the pre-test and positive attitude was found with good total score of knowledge in the post-test. So, there is a need to improve knowledge and change attitude of nursing students about genetic counseling. As well as genetic counseling should be included in the university-nursing curriculum and should be reviewed periodically to accommodate the relevant fast change in the science

  4. [The ancient Alexandria school of medicine].

    A famous medical school was established in old Alexandria during the third century BC. Although mainly Greek in essence, and following the Hippocratic teachings, it was heavily tainted by the medical practices of ancient Egypt. Anatomy was particularly advanced due to the possibility of dissecting the human body. The most important Alexandrian physicians were Herophilus and Erasistratus. Many graduates of this medical school traveled and practiced throughout the Mediterranean basin. Galen, the famous Roman physician studied in Alexandria before practicing in Rome. His teachings and writings survived well into the sixteenth century and formed the basis of more modern medical practices during the renaissance. These writings were conserved partly by Christian monks and partly by Arab and Jewish scholars of the middle ages. The medical school of Alexandria was still active until late in the 3rd century AD. However, it slipped slowly into oblivion after the fire of 389 AD, which also devastated its famous library. PMID:11875862

    This image of Alexandria was taken by astronauts on board the International Space Station in December 2000 using an Electronic Still Camera. A wider-angle view (STS088-739-90) taken from the Space Shuttle in December 1998 is available for context. Alexandria (Al Iskandariya) occupies a T-shaped peninsula and strip of land separating the Mediterranean from Lake Mariout. Originally the town was built upon a mole (stone breakwater) called Heptastadium, which joined the island of Pharos (see referenced website, below) to the mainland. Since then sedimentary deposits have widened the mole. Since 1905, when the 370,000 Alexandrians lived in an area of about 4 sq km between the two harbors, the city (population 4 million; see referenced website, below) has grown beyond its medieval walls and now occupies an area of about 300 sq km. The Mahmudiya Canal, connecting Alexandria with the Nile, runs to the south of the city and, by a series of locks, enters the harbor of the principal port of Egypt (note ships). The reddish and ochre polygons west of Lake Mariout are salt-evaporation, chemical-storage, and water-treatment ponds within the coastal lagoon.

    Historical catalogues indicate that Alexandria was severely affected in the past by several tsunami events. The tsunami hazard in that area is mainly due to far-field tectonic sources. The two most famous earthquakes that generated tsunamis whose impact was experienced also by Alexandria and the surrounding area are the 365 AD and the 1303 earthquakes, whose sources are still a matter of debate but are frequently located in correspondence with the western and eastern sectors of the Hellenic Arc. Nowadays, Alexandria is the second biggest city in Egypt as regards population (3.9 million), it is a key economic area in northern Africa and it has a very important tourist activity. Hence the proper assessment of tsunami hazard-to-risk must be regarded as an important task, which was partially undertaken in the very recent past by projects such as TRANSFER (EU-FP6). It is also worth mentioning that the overall eastern Mediterranean is one of the areas chosen by the EU-FP7 Project TRIDEC to test a new generation Tsunami Early Warning Decision Support System. We assess the hazard by performing numerical simulations of tsunami impact in Alexandria through the worst-case scenario technique. We identify three main seismic sources: the western Hellenic Arc (reference event 365 AD, magnitude 8.3), the eastern Hellenic Arc (reference event 1303, magnitude 8.0) and the Cyprus arc (hypothetical scenario with magnitude 8.0, inferred from the tectonic setting and the historical seismic catalogues). All the simulations and the inundation maps are computed by means of the UBO-TSUFD code, developed and maintained by the Tsunami Research team of the University of Bologna, which solves the non-linear shallow-water equations allowing for the computation of run-up and inundation on nested grids. For each of the considered scenarios we compute all the relevant tsunami metrics, i.e. water elevation, current speed, flow depth and momentum flux. We find that the case that produces the most

    Alexandria is the second biggest city in Egypt as regards population, is a key economic area in northern Africa and has a very important tourist activity. Historical catalogues indicate that it was severely affected by a number of tsunami events. In this work we assess the tsunami hazard by running numerical simulations of tsunami impact in Alexandria through the Worst-case Credible Tsunami Scenario Analysis (WCTSA). We identify three main seismic sources: the Western Hellenic Arc (WHA - reference event AD 365, Mw = 8.5), the Eastern Hellenic Arc (EHA - reference event 1303, Mw = 8.0) and the Cyprus Arc (CA - hypothetical scenario earthquake with Mw = 8.0), inferred from the tectonic setting and from historical tsunami catalogues. All numerical simulations are carried out by means of the code UBO-TSUFD, developed and maintained by the Tsunami Research Team of the University of Bologna. Relevant tsunami metrics are computed for each scenario and then used to build aggregated fields such as the maximum flood depth and the maximum inundation area. We find that the case that produces the most relevant flooding in Alexandria is the EHA scenario, with wave heights up to 4 m. The aggregate fields are used for a building vulnerability assessment according to a methodology developed in the frame of the EU-FP6 project SCHEMA and further refined in this study, based on the adoption of a suitable building damage matrix and on water inundation depth. It is found that in the districts of El Dekhila and Al Amriyah, to the south-west of the port of Dekhila over 12 000 buildings could be affected and hundreds of them could incur in consequences ranging from important damage to total collapse. It is also found that in the same districts tsunami inundation covers an area of about 15 km2 resulting in more than 150 000 residents being exposed.

  15. Earthquake risk assessment of Alexandria, Egypt

    2015-01-01

    Throughout historical and recent times, Alexandria has suffered great damage due to earthquakes from both near- and far-field sources. Sometimes, the sources of such damages are not well known. During the twentieth century, the city was shaken by several earthquakes generated from inland dislocations (e.g., 29 Apr. 1974, 12 Oct. 1992, and 28 Dec. 1999) and the African continental margin (e.g., 12 Sept. 1955 and 28 May 1998). Therefore, this study estimates the earthquake ground shaking and the consequent impacts in Alexandria on the basis of two earthquake scenarios. The simulation results show that Alexandria affected by both earthquakes scenarios relatively in the same manner despite the number of casualties during the first scenario (inland dislocation) is twice larger than the second one (African continental margin). An expected percentage of 2.27 from Alexandria's total constructions (12.9 millions, 2006 Census) will be affected, 0.19 % injuries and 0.01 % deaths of the total population (4.1 millions, 2006 Census) estimated by running the first scenario. The earthquake risk profile reveals that three districts (Al-Montazah, Al-Amriya, and Shark) lie in high seismic risks, two districts (Gharb and Wasat) are in moderate, and two districts (Al-Gomrok and Burg El-Arab) are in low seismic risk level. Moreover, the building damage estimations reflect that Al-Montazah is the highest vulnerable district whereas 73 % of expected damages were reported there. The undertaken analysis shows that the Alexandria urban area faces high risk. Informal areas and deteriorating buildings and infrastructure make the city particularly vulnerable to earthquake risks. For instance, more than 90 % of the estimated earthquake risks (buildings damages) are concentrated at the most densely populated (Al-Montazah, Al-Amriya, and Shark) districts. Moreover, about 75 % of casualties are in the same districts.

    When one examines Alexandrian commentaries on works of Galen and Hippocrates, disclosed are essential guides to the Art of Medicine as practiced in the late fifth, sixth, and early seventh centuries. These are outlines and contents of a 'medical curriculum' in late Byzantine Alexandria, as well as Ravenna, and thanks to the patient and skilled labors of Dickson,' Duffy,2 Irmer, Palmieri, Pritchet, Westerink, and others, following and building on the pioneering studies of Bräutigam, Meyerhoff, and Temkin, medical historians can now peruse carefully edited Greek and Latin texts and generally reliable translations of some commentaries by Agnellus of Ravenna, John of Alexandria, Palladius, and Stephanus of Athens. Deeply experienced medical practitioners became teachers of would-be medical students in Alexandria and Ravenna. Alexandria had long functioned as a city reputed to be the home of medical instruction, and by ca. 550 or slightly later, teachers began to produce commentaries on the classic texts of Greek and Roman medicine, with Galen and Hippocrates as major authorities. Underpinning what the medical professors set down in their commentaries were extended lives spent in the actual practice of medicine, sometimes as military physicians (as may have been the case of Paul of Aegina in the early seventh century), sometimes as doctors who had gained lengthy experience in Alexandria itself, and sometimes as medical professionals who had emigrated to Egypt after successful careers in another part of the Greek-speaking eastern Roman Empire. Reflecting time as a medical student and later career in Constantinople, Aetius of Amida's Tetrabiblon foreshadows editorial mechanics and techniques of textual exegesis as they emerge more clearly with the medical commentators after 550. It may well be that Stephanus, 'the Philosopher and Physician', was originally from Athens, but whether he was or not, the attribution of an Athenian background suggests that non

    Medical establishments play important roles in different activities by using of modern technology to serve the humans and the environment through different departments in the establishment and its firms. Medical wastes are considered as a hazardous waste because they contain toxic materials, infectious, or non-infectious wastes and they are considered as a hazard to millions of patients, health care workers, and visitors. Treatment processes for medical wastes comprise autoclaving, microwaving, chemical disinfection, irradiation, plasma system, and incineration. Incineration is a thermal process, which destroys most of the waste including microorganisms. Combustion process must be under controlled conditions to convert wastes containing hazardous materials into mineral residues and gases. Hospital waste incinerators may emit a number of pollutants depending on the waste being incinerated. These pollutants include particulate matter, acid gases, toxic metals, and toxic organic compounds products of incomplete combustion, e.g., dioxins, furans, and carbon monoxide, as well as sulfur oxides and nitrogen oxides. So, there should be a reduction of emissions of most of these pollutants by air pollution control devices. This study was conducted in 51 medical establishments (ME) in Alexandria. To evaluate its incinerators. It was found that only 31.4% of total ME have their own incinerators to treat their medical waste. Also, the incinerators conditions were poor with incomplete combustion. So, the study recommend handling of all medical wastes of ME in Alexandria by the company which is responsible now for management of domestic solid wastes of the city. PMID:16900615

    TTV is a non enveloped, single-stranded, circular- DNA virus that has been assigned to the Family Circiniviridae. The primary mode of TTV transmission was proposed to be transfusion (and hence its name). Little is known about the clinical significance and the natural history of TTV infection. Hence, responsibility of the virus for specific liver disease is still debated. In our study, we tested ninety five blood donors attending Kom EL-Decka regional blood bank in Alexandria for the presence of TTV DNA in their sera by PCR technique. The same samples were tested for ALT and AST levels by colorimetric technique and for HBsAg and anti-HCV by the ELISA technique. Out of the 95 blood donors, 46 (48.4%) had TTV DNA in their sera. None of the 95 blood donors included in this study was positive for HBsAg, while 22 (23.2%) were anti-HCV positive. Out of the 22 anti-HCV positive blood donors, 13 (59.1%) were TTV DNA positive, while out of the 73 anti-HCV negative blood donors, 33 (45.2%) had TTV DNA in their sera. There was no statistically significant difference between the prevalence of TTV DNA and anti-HCV in blood donors. No biochemical evidence of liver disease potentially linked to the TTV infection was observed in our blood donors who were TTV DNA positive. Furthermore, the occurrence of elevated serum AST and ALT was most often linked to HCV rather than TTV. PMID:17187747

  10. Alexander the Great's tombolos at Tyre and Alexandria, eastern Mediterranean

    NASA Astrophysics Data System (ADS)

    Marriner, N.; Goiran, J. P.; Morhange, C.

    2008-08-01

    Tyre and Alexandria's coastlines are today characterised by wave-dominated tombolos, peculiar sand isthmuses that link former islands to the adjacent continent. Paradoxically, despite a long history of inquiry into spit and barrier formation, understanding of the dynamics and sedimentary history of tombolos over the Holocene timescale is poor. At Tyre and Alexandria we demonstrate that these rare coastal features are the heritage of a long history of natural morphodynamic forcing and human impacts. In 332 BC, following a protracted seven-month siege of the city, Alexander the Great's engineers cleverly exploited a shallow sublittoral sand bank to seize the island fortress; Tyre's causeway served as a prototype for Alexandria's Heptastadium built a few months later. We report stratigraphic and geomorphological data from the two sand spits, proposing a chronostratigraphic model of tombolo evolution.

    Background: Solid waste management has emerged as an important human and environmental health issue. Municipal solid waste workers (MSWWs) are potentially exposed to a variety of occupational biohazards and safety risks. The aim of this study was to describe health practices and safety measures adopted by workers in the main municipal company in Alexandria (Egypt) as well as the pattern of the encountered work related ill health. Methods: A cross-sectional study was conducted between January and April 2013. We interviewed and evaluated 346 workers serving in about 15 different solid waste management activities regarding personal hygiene, the practice of security and health care measures and the impact of solid waste management. Results: Poor personal hygiene and self-care, inadequate protective and safety measures for potentially hazardous exposure were described. Impact of solid waste management on health of MSWWs entailed high prevalence of gastrointestinal, respiratory, skin and musculoskeletal morbidities. Occurrence of accidents and needle stick injuries amounted to 46.5% and 32.7% respectively. The risk of work related health disorders was notably higher among workers directly exposed to solid waste when compared by a group of low exposure potential particularly for diarrhea (odds ratio [OR] = 2.2, 95% confidence interval [CI] = 1.2-3.8), vomiting (OR = 2.7, 95% CI = 1.1-6.6), abdominal colic (OR = 1.9, 95% CI = 1.1-3.2), dysentery (OR = 3.6, 95% CI = 1.3-10), dyspepsia (OR = 1.8, 95% CI = 1.1-3), low back/sciatic pain (OR = 3.5, 95% CI = 1.8-7), tinnitus (OR = 6.2, 95% CI = 0.3-122) and needle stick injury (OR = 3.4, 95% CI = 2.1-5.5). Conclusions: Workers exposed to solid waste exhibit significant increase in risk of ill health. Physician role and health education could be the key to assure the MSWWs health safety. PMID:24932385

    Alexandria is the second biggest city in Egypt with regards to population, is a key economic area in northern Africa and has very important tourist activity. Historical records indicate that it was severely affected by a number of tsunami events. In this work we assess the tsunami hazard by running numerical simulations of tsunami impact in Alexandria through the worst-case credible tsunami scenario analysis (WCTSA). We identify three main seismic sources: the western Hellenic Arc (WHA - reference event AD 365, Mw = 8.5), the eastern Hellenic Arc (EHA - reference event 1303, Mw = 8.0) and the Cyprus Arc (CA - hypothetical scenario earthquake with Mw = 8.0), inferred from the tectonic setting and from historical tsunami catalogues. All numerical simulations are carried out in two sea level conditions (mean sea level and maximum high-tide sea level) by means of the code UBO-TSUFD, developed and maintained by the Tsunami Research Team of the University of Bologna. Relevant tsunami metrics are computed for each scenario and then used to build aggregated fields such as the maximum flood depth and the maximum inundation area. We find that the case that produces the most relevant flooding in Alexandria is the EHA scenario, with wave heights up to 4 m. The aggregate fields are used for a building vulnerability assessment according to a methodology developed in the framework of the EU-FP6 project SCHEMA and further refined in this study, based on the adoption of a suitable building damage matrix and on water inundation depth. It is found that in the districts of El Dekhila and Al Amriyah, to the south-west of the port of Dekhila, over 12 000 (13 400 in the case of maximum high tide) buildings could be affected and hundreds of them could sustain damaging consequences, ranging from critical damage to total collapse. It is also found that in the same districts tsunami inundation covers an area of about 15 km2, resulting in more than 150 000 (165 000 in the case of maximum high

    Three geo-archaeological sites at the North Coast and Alexandria, namely, the Alexandria wall (El Shalalat Park site), Abu Soir temple, and Marina excavations, were investigated to determine the negative impact of a salty environmental condition. The monuments suffer from rock decay of different rates. The geo-archaeological sites were built mainly from oolitic limestone blocks (i.e., the Alexandria wall at the El Shalalat Park site and Abu Soir temple) or excavated on them (i.e., Marina excavations). Field inspection and a lab analysis were carried out to understand the weathering mechanism. Salt weathering criteria such as disintegration, pitting, scaling, exfoliation, and honeycomb are observed on the Alexandria wall and upper parts of the Abu Soir temple, while dangerous cracks are detected on the Marina excavation tombs. The petrographic study of the oolitic limestone samples shows that they consist mainly of oolities and drusy sparite as a cement (oolitic grainstone). Some oolities have quartz grains as nuclei. Hydrochemical analysis shows that the total dissolved salts of extracted solutions of the North Coast quarry samples range from 539 to 686 ppm and dramatically increase (i.e., ten times) for extracted solutions from monument samples, ranging from 5395 to 6880 ppm. The dominant cation is sodium while the dominant anion is chlorine. Acid insoluble residue analysis shows that the carbonate content ranges from 89.2% to 96.4% for fresh samples from quarries and from 9.2% to 94.8% for weathered monument samples. The weight loss of the quarry oolitic limestone samples range from 30.7% to 32.7% and its physical and mechanical properties become worse after being subjected to 15 cycles of a durability simulation soundness test (using a sodium sulphate solution). Our main recommendations are to use suitable grouting for binding the cracks, high durability reconstruction rocks, and suitable cleaning methods to remove salts from the monuments.

  16. Comparative analyisis of energy consumption of selected buildings on morehead state university's main campus

    Brandt, Ronald E.

    Currently there is a need for energy efficiency on the main campus of Morehead State University main campus. Evidence shows that there is room for improvement in order to lower the usage and cost efficiency at MSU. The purpose of this study is to propose, that Net Zero technology should be implemented towards the main campus of Morehead State University in the near future. The goal is to come up with a study of comparing selected current traditional buildings with the LEED buildings (Wellness Recreational Center and CHER building). To form this analysis will be applied using SPC software on Energy usage for year by year trends from 2012. In conclusion, Net-Zero construction has steadily increased since then, with the number of completed buildings more than doubling since 2008, according to the latest study. Thanks to advances in structural insulation, energy-efficient appliances, this will help the MSU campus in the near future. As for energy efficiency, to make sure we have plenty of energy in the future, it's up to all of us to use energy wisely. We must all conserve energy and use it efficiently. It's also up to those who will create the new energy technologies of the future..

  17. Main-sequence of star-formation, between universality and tension

    2015-08-01

    We will present a new method to push the deepest Herschel surveys even deeper in sensitivity and redshift range. A comparison to UV techniques such as the Lyman break technique will be given showing that a population of M*>5x10^10 Msun galaxies is systematically missed by this standard approach at high z. We will discuss how SFR estimates of starbursting galaxies can be wrongly estimated when using the UV corrected for extinction. A discussion of the relative growth of disks and bulges will be presented.We will show that at least 2/3 of the star-formation history of galaxies took place in a main-sequence mode, i.e. with a characteristic specific SFR +/- 0.3 dex, suggesting that star-formation at the scale of galaxies over the Hubble time is a relatively universal process. This result matches surprisingly well the cold flow paradigm which states that at least 2/3 of the mass growth of galaxies came from smooth accretion of intergalactic matter suggesting that the main-sequence is a direct result of smooth gas accretion. However we will also show that both paradigms lead to a major tension in their relative growth rates as a function of cosmic time showing that either a major regulatory process of star-formation is still missing or that we misunderstand the behavior of baryons at large scales.

    2013-04-01

    Researchers from the University of Maine Physics Education Research Laboratory are conducting several investigations of the learning and teaching of physics beyond the introductory level. Content topics include intermediate mechanics, electronics, thermodynamics and statistical mechanics. One focus of our work is the identification and addressing of specific student difficulties with topics such as damped harmonic motion, bipolar junction transistor (BJT) circuits, work, entropy, and the Boltzmann factor. Student understanding and use of the underlying mathematics has been one important emerging theme, including definite integrals, partial derivatives, and linear differential equations. Recent work in mechanics has focused on understanding the interplay of mathematical and physical reasoning when describing damped harmonic motion, including framing and representational issues. In electronics, there has been an ongoing investigation of student understanding of the behavior of basic BJT follower and amplifier circuits as well as related issues of signal and bias. In thermal physics, student understanding of state functions, heat engines and the Carnot cycle, the First and Second Laws of thermodynamics, and the macroscopic and microscopic perspectives on entropy have been investigated. The greater content sophistication in these courses has drawn attention to the specific needs, constraints, and advantages of instructional materials tailored to the upper division. Future directions include more attention to interdisciplinary topics across mathematics, physics, and engineering in particular, as well as metacognition in the laboratory.

    A cross-sectional survey on tobacco use in the city of Alexandria, Egypt, used an interview questionnaire based on World Health Organization guidelines. The study in 2000 included 2120 participants aged 15 to 86 years. More than a quarter (27.2%) were current smokers (25.5% daily smokers and 1.7% occasional smokers) and 3.5% were ex-smokers. Current smokers spent 23.1% of their family income on tobacco. The prevalence of current smoking was significantly higher among men (48.5%) than women (1.5%) and the mean age of initiation of smoking was lower among men (18.1 years) than women (22.6 years). The high prevalence of tobacco use among men is of concern, so too is the likelihood that tobacco use will increase among women. Further research is needed into factors that prevent people from starting smoking and assist them stopping smoking. PMID:15603046

    University at Albany successfully designed, constructed and is operating a new student housing building that utilizes ground source heat pump (GSHP) for heating and cooling the entire 191,500SF building. The installed system consists of a well field with 150 bores, 450 feet deep and (189) terminal heat pump units for a total capacity of 358 Tons cooling and 4,300 MBtu/h heating. The building opened in Fall 2012. The annual energy use and cost intensity of the building, after the changes made during the first 2 years’ of operation is 57kBtu/SF/Year and $1.30/SF/Year respectively. This is approximately 50% lower than the other residential quads on campus, despite the fact that the quads are not air-conditioned. The total project cost from design through 3-years of operations is approximately $6 Million, out of which $5.7 Million is for construction of the GSHP system including the well field. The University received a $2.78 Million grant from the Department of Energy. The estimated utility cost savings, compared to a baseline building with conventional HVAC system, is approximately $185,000. The estimated simple payback, after grant incentives, is 15 years. Additionally, the project has created 8.5FTE equivalent jobs.

    Aim: This study aimed at investigating the microbial contamination of mobile phones in a hospital setting. Methods: Swab samples were collected from 40 mobile phones of patients and health care workers at the Alexandria University Students’ Hospital. They were tested for their bacterial contamination at the microbiology laboratory of the High Institute of Public Health. Quantification of bacteria was performed using both surface spread and pour plate methods. Isolated bacterial agents were identified using standard microbiological methods. Methicillin-resistant Staphylococcus aureus was identified by disk diffusion method described by Bauer and Kirby. Isolated Gram-negative bacilli were tested for being extended spectrum beta lactamase producers using the double disk diffusion method according to the Clinical and Laboratory Standards Institute recommendations. Results: All of the tested mobile phones (100%) were contaminated with either single or mixed bacterial agents. The most prevalent bacterial contaminants were methicillin-resistant S. aureus and coagulase-negative staphylococci representing 53% and 50%, respectively. The mean bacterial count was 357 CFU/ml, while the median was 13 CFU/ml using the pour plate method. The corresponding figures were 2,192 and 1,720 organisms/phone using the surface spread method. Conclusions: Mobile phones usage in hospital settings poses a risk of transmission of a variety of bacterial agents including multidrug-resistant pathogens as methicillin-resistant S. aureus. The surface spread method is an easy and useful tool for detection and estimation of bacterial contamination of mobile phones. PMID:25699226

    The future of meaningful scientific research in the United States depends heavily upon the quality of the science and mathematics education received by students in our grade K-12 education system. The National Science Foundation's GK-12 Teaching Fellowship Program provides opportunities for scientific enrichment for students and their teachers at the K-12 level. Currently in its fifth year at the University of Maine, Orono, the program is one of over 100 such programs in the country. Last year, the program was honored by the New England Board of Higher Education with a Regional Award for Excellence in Project Achievement. The program has three broad goals: to enrich the scientific education of students by providing equipment, role models, and expertise that they may not otherwise be exposed; to provide professional development for teachers through curriculum enrichment and participation at scientific conferences; and to improve the teaching and communication skills of fellows. Fellows represent a broad spectrum of research interests at the University of Maine, including Biology, Chemistry, Engineering, Forestry, Geological Sciences, and Marine Science. This past year, 13 graduate students and 1 undergraduate student worked with 52 teachers and 2300 students in 26 schools across the state of Maine. The benefits of this program are tangible and substantial. New awareness of the innovative ways that K-12 and University education systems can work together to promote hands-on science and the scientific method, is one of the major contributions of the NSF GK-12 Teaching Fellowship Program.

    This cross-sectional study was carried to determine the prevalence of intestinal parasitic infections among mentally handicapped individuals in Alexandria, Egypt, in the period from December 2012 till November 2013. The study was conducted on 200 institutionalized and non-institutionalized mentally handicapped individuals. Fresh stool samples were subjected to different stains including; trichrome for detecting intestinal protozoa, modified acid fast stain for intestinal coccidia and quick hot gram chromotrope stain for Microsporidia. Also they were processed by Kato-Katz and formol ethyl acetate techniques for intestinal helminths. Additionally, blood samples were collected for measuring hemoglobin levels. Out of 200 mentally handicapped individuals, 87 (43.5%) were infected. The infection rates were 44.6% and 42.6% for non-institutionalized and institutionalized people, respectively. Regarding gender, 46.7% and 38.5% were reported for the males and females respectively. The most common parasites detected were: Cryptosporidium sp. (23.5%), microsporidia (15%), Giardia lamblia (8.5%), Dientamoeba fragilis (8%), Cyclospora cyatanensis (7.5%), Blastocystis hominis (6.5%), Entamoeba histolytica (5.5%) and Entamoeba coli (2.5%). Rates for Isospora belli and Enterobius vermicularis were estimated to be 1.5% for each, while lower rate was reported for Iodamoeba butschlii (1.0%). Prevalence of infections among mentally handicapped individuals are indications for several risk factors, including improper sanitary hygiene and illiteracy about personal hygiene. Therefore, frequent investigations, health care and medical intervention are needed. PMID:26878626

    1983-03-01

    This paper presents a summary of the first phase of the EPA project, which encompasses surveys of residues from industrial sources in Alexandria. Studies to date indicate that wastes from various industries can be recovered economically. Wastes such as tin cans, glass, wastepaper, and food residues from processing of fruits, starch, and beer are examples of reusable industrial wastes in Egypt. The results of experimental studies for reuse of residues from oil refining, starch and yeast processing, and steel pickling are presented. Spent clay from edible oil refining is currently discarded, causing both handling and disposal problems. This clay contains as much as 40% oil; 90% can be recovered by extraction. The recovered oil can be successfully used in soap production, and the spent clay can be reused in oil bleaching. Other examples include starch and yeast wastes, which can be used for animal feed, and spent pickling liquor, which can be used as a coagulant aid for treating paper mill wastewater. A centralized system for collecting and treating hazardous residues is proposed to permit economical recovery of valuable materials.

    Polyethylene samplers (PEs) were deployed at 11 locations in Alexandria, Egypt during summer and winter to test and characterize them as passive samplers for concentrations, sources, and seasonal variations of atmospheric concentrations of polycyclic aromatic hydrocarbons (PAHs). PE-air equilibrium was attained faster for a wider range of PAHs during the winter season possibly due to increased wind speeds. Calculated PE-air partitioning constants, K(PE-A), in our study [Log K(PE-A) = 0.9426 × Log K(OA) - 0.022 (n = 12, R(2) = 0.99, Std error = 0.053)] agreed with literature values within <46%. For parent (except naphthalene), mono- and dialkylated PAHs, active sampling based concentrations of PAHs were within an average factor of 1.4 (1.0-5.6) compared to the PE based values. For C(3-4) alkylated PAHs, K(PE-A) values were lower than predicted, on average by ~0.8 log units per carbon in the alkylation. Enthalpies of vaporization (ΔH(vap)) accurately corrected K(PE-A)s for temperature differences between winter and summer sampling. PAH profiles were dominated by naphthalene, phenanthrene, and alkylated phenanthrenes. Calculated diagnostic ratios indicated that PAHs originated mainly from vehicle emissions. PMID:22397460

    Muscat of Alexandria is known in Italy as Zibibbo. Zibibbo nero, red-wine grapes, is a sport mutation of Zibibbo variety. A biochemical and molecular characterization of berry colour (VvMybA1 and VvMybA2 genes, Vitis vinifera MYeloBlastosis) and aroma Muscat (VvDXS gene, 1-deoxy-D-xylulose 5-phosphate synthase) traits in both Zibibbo cultivars was performed, as well as ampelographic and genetic identification analyses. Molecular investigations were performed also for two putative Zibibbo parents (Moscato Bianco and Triboto), in order to prove the white-to-red shift of the red-skinned mutant. Ampelographic and genetic analysis demonstrated the high similarity between Zibibbo and Zibibbo nero, as well as a comparable aroma profile, characterized mainly by high content of linalool, geranic acid and geraniol (about 70 %). The Zibibbo nero anthocyanin profile was characterized by a high proportion in cyanidin-3-O-glucoside (about 69.23 %). The molecular characterization of VvMybA1 and VvMybA2 locus detected non-functional alleles for white-skinned samples, while also the functional alleles were observed for red-skinned samples. About the VvDXS locus, the aromatic varieties showed the typical pattern of Muscat variety, while Triboto (Zibibbo parent) showed the non-Muscat-like flavour pattern. The colour locus structure of Zibibbo and its putative parents suggested that Zibibbo nero is a berry colour revertant of Zibibbo. PMID:25380987

    2005-12-01

    Historians have long postulated that a settlement called Rhakotis was present on Egypt's Mediterranean coast in the area subsequently occupied by the city of Alexandria. To date, however, the precise position of that site has not been located in the immediate area of the city founded by Alexander the Great. Also undefined are the earliest phases of occupation that pre-date Alexandria on Pharos Island and in the harbour area. A geoarchaeological project emphasizing sediment cores in Alexandria's Eastern Harbour now provides evidence of human occupation adjacent to these settings prior to establishment of Greece's great port in 332 BC. A radiocarbon-dated stratigraphic unit, defined as Middle Sand (III) and older than the 4th century BC, includes locally produced ceramics, along with rock fragments of non-local origin, and increased content of sand-sized heavy mineral and organic matter. Together, these date at least to Egypt's Late Dynastic Period (712-332 BC). Moreover, the geographic positions of core sites containing these markers indicate that early habitation occurred both at Pharos Island and on the mainland where the future Alexandria would be built. New findings in cores recovered in this marine environment are adding to knowledge of both natural processes and effects of human activity in early Alexandria.

    The emissions and ashes from medical waste incinerators might perform a threat to the environment and the public health. The aim of the present work is to evaluate the emissions and ashes of six medical wastes incinerators in six hospitals in Alexandria. Five air pollutants were sampled and analyzed in the emissions comprising smoke, lead, carbon monoxide, sulphur dioxide and nitrogen dioxide . Ash samples were analyzed for bacterial count, volatile substances, lead and cadmium. Shape and color of ash were observed visually. The results of the present study have revealed that all the average values of gases in the six incinerators were within the limits stated in Egyptian environmental law, where as carbonaceous particulate (smoke) averages of the six incinerators have exceeded the maximum allowable limit in the law. On the other hand, lead concentration in emissions were far below the maximum allowable limit in the law. Incinerator No 6 emissions have been significantly higher in CO, NO2, SO2 and smoke concentration than the other five incinerators P<0.001, P<0.0006, P<0.0001, and P<0.002 respectively. There was no significant variation in bacterial count of ash samples at 20 degrees C and 37 degrees C between the six studied incinerators. Volatile substance percentage of ash samples in the six incinerators were much higher than the recommended percentage. There was a highly significant variation between the six incinerators (p<0.005). Lead and cadmium concentrations in ash samples were much higher than those in developed countries, meanwhile, more or less as those in developing countries. It is recommended to state specific realistic emissions limits for medical waste incinerators and to substitute sporadic incinerators in hospitals by two central incinerators in proper places outside the city.

    The objective of this descriptive, hospital-based comparative cross-sectional survey was to determine gender differences in factors associated with patients' decisions to seek treatment for urinary incontinence (Ul). Using an interview questionnaire, data were collected from 353 patients attending clinics at hospitals in Alexandria, Egypt. There were differences between males and females regarding specific psychosocial factors motivating health care seeking behaviour. Women had fewer hospital admissions and hospital days and less use of diagnostic procedures and surgery. More women suffered from at least one negative impact on their social lives compared to men. The impact of symptoms on quality of life appeared to be the main trigger for seeking help for UI in both men and women. PMID:21218742

    It is generally accepted that Alexandria ad Aegyptum was founded ex nihilo in 331 BC by Alexander the Great, rapidly growing into one of antiquity's most opulent economic and intellectual centers. However, ancient texts by Strabo (17.1.6) and Pliny (NH 5.11.62) suggest the existence of a pre-Hellenistic settlement named Rhakotis. This literary evidence has fuelled contentious scholarly debate for decades. Here we present new geochemical data from Alexandria's ancient bay sediments, elucidating unequivocal proof for pollutant lead (Pb) input into the harbor during the Egyptian Old Kingdom (2686-2181 BC). A second contamination peak is detected during the Iron Age (1000-800 BC), at the end of the prosperous Ramesses reigns. These findings evidence thriving pre-Hellenistic settlements in Alexandria. During the Greek and Roman periods, we expound the largest Pb pollution ever encountered in ancient city sediments with Pb levels twice as high as those measured in contemporary industrialized estuaries.

    Recent multidisciplinary investigations of sediment cores from the ancient marine bay of Alexandria (Egypt) have documented local human activities during the Iron Age (circa 900-1000 B.C.) prior to Alexander the Great's arrival in 331 B.C. (Goiran, 2001; Véron et al., 2006; Stanley et al., 2007, 2010), corroborating the existence of the so-called "Rakhotis" as evoked in previous archaeological literature (Jondet, 1916; Weill, 1919; Chauveau, 1999; Baines, 2003). Lead (Pb) Isotopic Analyses (LIA) from Alexandria Bay indicate a possible anthropogenic imprint as early as circa 2300-2650 (±200) B.C. and, to a lesser extent, 3500-3800 (±170) B.C. (Véron et al., 2006). Here we demonstrate that LIA in sediments from the nearby Maryut Lagoon display isotopic anomalies resulting from the release of contaminant Pb into the Lagoon during the Egyptian Early dynastic (at 2897 ± 187 B.C) and Predynastic (at 3520 ± 145 B.C.) periods that corroborate geochemical data from Alexandria Bay. Pb concentrations in Maryut sediments show enrichments that mirror isotopic findings. The absence of contaminant Pb imprints within the sediments from the nearby Nile Canopic branch confirms that isotopic anomalies found in Alexandria Bay and Maryut Lagoon sediments are local and do not originate from long-distance transport of contaminant Pb associated with Nile suspended material and/or wind-derived aerosols. LIA in Alexandria sediment cores correspond to commonly mined Pb and Cu (copper) ores from Turkey (Black Sea region), Cyprus, Crete and the Oman Gulf. LIA substantiate the use of copper-based relics in the Alexandria region during the Pre and Early dynastic periods, and provide insights into metal trading within the Eastern Mediterranean during the Chalcolithic-Early Bronze Age transition, 6000 years ago.

  15. [Philo of Alexandria and his views on health and sickness].

    Kaiser, Otto

    2015-01-01

    Philo of Alexandria, Torah scholar and philosopher of religion, (c. 20 BC to 50 BCE) is the first Middle Platonic philosopher whom we know through his own works. His thinking was determined by the two antitheses of God and world, and virtue and vice. The Logos (divine reason) mediates between the transcendent God and the earthly world. His thoughts on health and illness and on the possibilities and limitations of medicine are testimony to his comprehensive philosophical education as well as to his belief in God as ruler of the world and of human life. He saw human health as the reward for self-control for which one was best prepared by the classical education programme. Self-control and physical exercise were therefore, in his view, possible guarantors of health, and a coach potentially more important than a physician. Illnesses, if they result from the loss of self-control, may point to the necessity for penitence. Philo therefore saw virtuousness as the safest precondition for a healthy and cheerful life. That the life forces increase during youth and diminish in old age is part of destiny. Similarly, illness can be brought about by strokes of fate. If illness occurred in this or any other way, medicine was there to help and its success or failure depended on divine providence. Like Jesus Sirach, the Jewish scholar who taught around a hundred years earlier, Philo did not think it sinful to use medical help if one was ill, seeing that God himself had made natural remedies available. He compared the importance of physicians for their patients to that other professionals have in people's lives. Philo did not provide a compendium on the work of the physician, but he gave indications, on nutrition for instance, or on the use of laxatives and fragrances, or that complaints can be necessary stages of recovery. Philo also asked himself whether physicians were always obliged to tell patients the truth. The only case of illness he described in sufficient detail was one of

    2015-02-01

    The paper presents technology and results of measurements of the steel construction of the skylight of the Main Hall of the Warsaw University of Technology. The new version of the automated measuring system has been used for measurements. This system is based on Leica TCRP1201+ total station and the TCcalc1200 software application, developed by the author, which operates on a laptop computer connected with the total station by the wire. Two test measurements were performed. Each of them consisted of cyclic measurement using the polar method, from one station; points located on the skylight construction, as well as control points located on concrete, bearing poles, were successively measured. Besides geometrical values (such as Hz, V angles and the slope distance D), the changes of temperature and atmospheric pressure, were also recorded. Processed results of measurements contained information concerning the behaviour of the skylight; asymmetry of horizontal displacements with respect to the X axis have been proved. Changes of parameters of the instrument telescope and changes of the instrument orientation were also stated; they were connected with changes of the temperature. The most important results of works have been presented in the form of diagrams.

    Abu Kir Bay, east of Alexandria, is affected by two main point sources of pollution, namely Tabia Pumping Station and Lake Edku Outlet. Chromium was measured in the Bay effluents, sea water, marine organisms of different trophic levels, and sediments. Chromium concentration and mass emission from TPS (242 μg l -1 and 436 kg d -1) to the Bay are very high compared to those of Lake Edku Outlet (33 μg l -1 and 116 kg d -1). Average Cr concentrations in the Bay coastal waters during the period of study, were 0·120 μg l -1, 0·775 μg l -1 and 1·185 μg l -1, respectively, for Cr(III), Cr(VI), and particulate pphase. The surface distribution of Cr in the coastal waters showed the impact of Tabia Pumping Station on the Bay. On the basis of sediment concentrations of Cr in Abu Kir Bay, two 'hot spots' of the element were identified. The area around Tabia Pumping Station outfall (> 300 μg g -1 dw) and another one in the immediate vincinity of Lake Outlet (> 200 μg g -1 dw). Chromium concentrations in Abu Kir Bay organisms increased in the following order: mixed plankton (68 μg kg -1) > Sardina pilchardus (80 μg kg -1) ⩾ Mugil capito (82 μg kg -1) > Mullus barbatus (111 μ kg -1) > Solea solea (123 μg kg -1) > Penaeus kerathurus (168 μg kg -1 > Donax trunculus (209 μ kg -1) > Neptunus pelagicus (369 μg kg -1) > Ulva species (1867 μg kg -1) > Enteromorpha species (3345 μg kg -1). The sequence is consistent for organisms from both west and east Abu Kir Bay, regardless of the significantly low Cr concentrations of the latter. The study showed that algae and crabs play a critical role in the biological transport of Cr and can be considered the best accumulators of the element. From the total amount of Cr flux to the Bay, 552 kg d -1, flushing of the Bay to the open sea removes 262 kg d -1, and sedimentation within the Bay is 242 kg d -1. Finally, an input/output box model for Cr in Abu Kir Bay was constructed to help in understanding its biogeochemical cycle.

    The assessment of the radiological risk related to the inhalation of radon and radon its progeny is based mainly on the integrated measurement of radon in both indoor and outdoor environments. The exhalation of radon from the earth's crust and building materials forms the main source of radon in the indoor environment. This study has been undertaken for the purpose of health risk assessment. In this comparative study, the indoor radon level, radium content, radon exhalation rate and concentration of soil radon are measured using the Can Technique. Soil samples were collected simultaneously from different geological formations of the same area for laboratory measurement of the radon exhalation rate. The radon exhalation rate was measured in the laboratory using LR-115 type II plastic track detectors. The indoor radon concentrations in this study area were found to vary from 44±9 to 132±31 Bq m(-3) with an average of 72±29 Bq m(-3). The seasonal variations of the indoor radon reveal the maximum values in the winter and in summer in different dwellings of Alexandria city. The annual effective dose varies from 0.75 to 2.2 mSv with an average value of 1.34 mSv. The radon exhalation rate was found to vary in the ranges 8.31-233.70×10(-3) Bq kg(-1) h(-1), 0.48-15.37 Bq m(-2) h(-1) with an average 47.97×10(-3) Bq kg(-1) h(-1), (3.14 Bq m(-2) h(-1)). The radium content in soil varies from 3.14 to 39.60 Bq kg(-1) with an average of 11.55 Bq kg(-1). The significance of this study is discussed in details from the point of view of radiation protection. PMID:23070484

    Many invaluable underwater buildings of archaeological interest in Alexandria were discovered in 1996 at different sites in the Eastern Harbour of Alexandria. There is a belief that the best way to protect these invaluable heritages is to transfer them to an underwater park or museum. Obviously, the execution of such a project depends essentially upon the water quality (including water transparency) improving in the future. The harbour is presently polluted by discharge of wastewater effluents from different sources. It has recently been decided to restore this important coastal area through: (1) stopping the direct discharge of wastewater effluents into this semi-enclosed harbour in 1993 and (2) gradually reducing the discharge of the municipal wastewater through marine outfalls at two sites lying at the outer sides of the harbour. Zero discharge is expected to be effective by the end of the year 2001. The present work, therefore, is a follow up of the study of water quality in the harbour after 1993: in 1996 and 1999-2000. The water quality of an open sea reference station was also studied for comparison. The results reveal occurrence of an improvement of the environmental conditions in the harbour. The water has turned from being eutrophic to mesotrophic. The harbour is expected to become meso/oligotrophic as soon as the complete cessation of the discharge from the two outside sources is attained. PMID:12787619

  5. Using a series of satellite methods to assess land subsidence in Alexandria

    Delta regions have been given considerable attention in recent years as these coastal areas are subject to subsidence processes that may exacerbate the exposure and risks to climate change-related sea level impacts. For instance, Hanson et al. (2011) considered an additional 0.5 m increase in relative sea level rise projections by 2070s for all large port cities established on delta regions. As a result of their analysis, Alexandria was ranked 11 in terms of exposure to coastal flooding. Within the Cecile project we have revisited the issue of land subsidence in Alexandria by: (1) examining the reprocessed data from the GPS station that is operational since 2001 near the historical tide gauge; and (2) investigating the results from the refined method of combining altimetry and tide gauge data. Both independent methods yield consistent rates of vertical land movements of 0.1+/-0.3 mm/yr at the GPS station and -0.4+/-0.2 mm/yr at the tide gauge, which are separated by 3 km. Details can be found in Santamaria-Gomez et al. (2012) and Wöppelmann and Marcos (2012), respectively. These observational results reveal that Alexandria is subject to a moderate rate of land subsidence for the past decades around 20 times lower than the values adopted by Hanson et al. (0.5 m between 2005 and 2070) to assess the exposure of populations and assets in delta regions. To further explore the areal extension of these point-wise results, we have used synthetic aperture radar (SAR) interferometry satellite techniques, namely the persistent scatterers interferometric analysis (PSI) to produce a mean velocity map over the period 2002-2010 corresponding to 49 SAR data acquired over Alexandria by the satellite Envisat. The results from the PSI analysis remarkably confirm the relative local stability between the tide gauge and the GPS stations. The two closest persistent scatterers to those stations give a consistent differential motion of 0.6 mm/yr, at the limit of the capability of the PSI

    Objective To evaluate the clinical characteristics of patients with hematological disease admitted to the intensive care unit and the use of noninvasive mechanical ventilation in a subgroup with respiratory dysfunction. Methods A retrospective observational study from September 2011 to January 2014. Results Overall, 157 patients were included. The mean age was 45.13 (± 17.2) years and 46.5% of the patients were female. Sixty-seven (48.4%) patients had sepsis, and 90 (57.3%) patients required vasoactive vasopressors. The main cause for admission to the intensive care unit was acute respiratory failure (94.3%). Among the 157 studied patients, 47 (29.9%) were intubated within the first 24 hours, and 38 (24.2%) underwent noninvasive mechanical ventilation. Among the 38 patients who initially received noninvasive mechanical ventilation, 26 (68.4%) were subsequently intubated, and 12 (31.6%) responded to this mode of ventilation. Patients who failed to respond to noninvasive mechanical ventilation had higher intensive care unit mortality (66.7% versus 16.7%; p = 0.004) and a longer stay in the intensive care unit (9.6 days versus 4.6 days, p = 0.02) compared with the successful cases. Baseline severity scores (SOFA and SAPS 3) and the total leukocyte count were not significantly different between these two subgroups. In a multivariate logistic regression model including the 157 patients, intubation at any time during the stay in the intensive care unit and SAPS 3 were independently associated with intensive care unit mortality, while using noninvasive mechanical ventilation was not. Conclusion In this retrospective study with severely ill hematologic patients, those who underwent noninvasive mechanical ventilation at admission and failed to respond to it presented elevated intensive care unit mortality. However, only intubation during the intensive care unit stay was independently associated with a poor outcome. Further studies are needed to define predictors of

    The emergence of infections caused by multidrug-resistant Gram-negative bacteria, in particular Pseudomonas aeruginosa, Acinetobacter baumannii, and Klebsiella pneumoniae, has necessitated the search for alternative therapy by either introducing new agents or renewing interest in old agents. This study compares the in vitro activity of tigecycline (TIG), recently introduced to Egyptian market, to other potentially active antimicrobials as Colistin (COL), imipenem (IPM), levofloxacin (LEV), and piperacillin/tazobactam (PIP/TAZ) against 67 Gram-negative clinical isolates obtained from El- Meery Hospital in Alexandria, Egypt. El-Meery Hospital is a 1,500-bed tertiary teaching hospital where TIG has not been previously used. Based on MIC(90)s, TIG was found to be a comparator to IPM and COL (MIC(90)= 8 μg/ml). LEV and PIP/TAZ were less active than TIG exhibiting high MIC(90)s. TIG inhibited 100% of Escherichia coli and K. pneumoniae and 60% of Ps. aeruginosa and A. baumannii isolates. In time-kill studies against IPM-resistant isolates, TIG showed bactericidal activity after 6 hours of contact against the Enterobacteriaceae isolates and after 3 hours for the tested Ps. aeruginosa isolates at 4× and 8× MIC. Against A. baumannii, TIG exerted a bacteriostatic effect. TIG demonstrated variable ability to suppress biofilm formation affecting mainly E. coli and A. baumannii isolates. These results point TIG to be a promising agent in treatment of infections caused by strains for which adequate therapy has been limited. As far as we know, this is the first report evaluating the in vitro activity of TIG against Egyptian clinical isolates. PMID:21875338

    A cross-sectional study was conducted to determine the extent and pattern of self-medication among adults, to identify their knowledge and practice concerning the purchased drugs and to calculate prescribing and purchaser care indicators. Following WHO methods, 35 pharmacies were randomly selected from districts in Alexandria city, Egypt. Of 1294 clients interviewed at these pharmacies, 1050 (81.1%) purchased self-medication; the commonest reason given was a belief that the condition was minor. The most frequently dispensed drugs were those for the respiratory system. The mean number of drugs per encounter was 1.10, mean cost LE 7.29 and mean dispensing time 2.53 minutes. Purchasers' knowledge and practice regarding the purchased drugs were poor. PMID:19731784

    On the authorship of Stephanus' of Alexandria On the great and sacred art of making gold many questions have arisen, and many scholars have in my estimation misunderstood and undervaluated it. As a commentary on selected passages of earlier alchemical texts it in fact offered an opportunity to its author to demonstrate wide rhetorical prowess, extensive learning, and significant breadth of philosophical understanding. In this article we present additional arguments in favour of Stephanus' authorship of the work; demonstrate that what was its concluding portion has been lost; indicate how two of the original lectures it contained have each been divided into two other lectures; and attempt to pin-point its exact date of composition on the basis of astronomical information it contains.

    We evaluated the effectiveness of cognitive behaviour therapy for 12-14-year-old school-children from a low socioeconomic area in Alexandria, Egypt during the academic year 2003-04. Our sample comprised 198 boys and 136 girls. Students were assessed using the Child Depression Inventory and the Coopersmith Self-Esteem Inventory. The frequency of depression was 9.6%; 7.1% in boys and 13.2% in girls. The 32 children with depression were offered cognitive behaviour therapy. Only 17 accepted the offer and received 9 sessions of therapy. They were assessed 3 months after the intervention using the same tools and the results indicate the short-term effectiveness of the therapy. PMID:17687835

    This paper describes two systems for managing 3D and anthropometric databases, namely Alexandria and Cleopatra. Each system is made out of three parts: the crawler, the analyzer, and the search engine. The crawler retrieves the content from the network while the analyzer describes automatically the shape, scale, and color of each retrieved object and writes down a compact descriptor. The search engine applies the query by example paradigm to find and retrieve similar or related objects from the database based on different aspects of 3D shape, scale, and color distribution. The descriptors are defined and the implementation of the system is detailed. The application of the system to the CAESAR anthropometric survey is discussed. Experimental results from the CAESAR database and from generic databases are presented.

    A study of gender differences in health care utilization and outcome of respiratory tuberculosis was carried out in Alexandria, Egypt. A cohort of 334 patients was followed-up for 8 months; 69.2% of cases were males. The pattern of tuberculosis symptoms was similar for both sexes. Women started treatment earlier than men. Women had significantly lower scores in knowledge, beliefs and attitudes about tuberculosis than men. Compliance was unsatisfactory for both sexes. Men tended to be more adherent to drugs and to sputum and X-ray examinations but there were no sex differences in compliance with health education and medical examinations. No significant sex differences in treatment outcome were found: the overall cure rate was 60.5% and treatment failure was 4.8%. Multiple regression analysis showed satisfaction with medical care was the only significant predictor of treatment failure. PMID:15748071

    Background: Data from Egyptian studies provide widely varying estimates on the prevalence of preinvasive cervical lesions. The aim of this study was to estimate the rate of cervical intraepithelial neoplasia (CIN) in Egyptian women living in Alexandria to clarify the need for implementing a national organized screening program and a vaccination program in our community. Materials and Methods: The study was conducted over a 6 years period and covered the different socioeconomic levels to have a representative sample for women living in Alexandria. All women included did not have any cervical disorder related complaints. Conventional Pap smears were obtained and diagnosed using the Bethesda system. Women with abnormal Pap smears were managed according to the 2006 consensus guidelines within the available facilities. Persistent abnormal cytological results were referred for colposcopic biopsy. Histological results were grouped into: Reactive changes, CIN 1, CIN 2/CIN 3 and adenocarcinoma in-situ (AIS). Results: Out of the 6173 smears included in the study 6072 (98.36%) were normal and only 101 (1.63%) were abnormal. After colposcopic biopsies, 0.08% had CIN 1, 0.03% had CIN 2, 3 and 0.01% had AIS. Conclusion: We concluded that cervical cancer screening programs, although life-saving for a number of women, are not a sufficiently high priority in our community. Money for national health screening programs should preferably be directed more towards recruiting women for breast cancer screening, since breast cancer accounts for about 33% of all female cancers in Egypt ranking number one, while cervical cancer ranks number 13.

    Quality control is the application of statistical techniques to a process in an effort to identify and minimize both random and non-random sources of variation. The present study aimed at the application of Statistical Process Control (SPC) to analyze the referrals by General Practitioners (GP) at Health Insurance Organization (HIO) clinics in Alexandria. Retrospective analysis of records and cross sectional interview to 180 GPs were done. Using the control charts (p chart), the present study confirmed the presence of substantial variation in referral rates from GPs to specialists; more than 60% of variation was of the special cause, which revealed that the process of referral in Alexandria (HIO) was completely out of statistical control. Control charts for referrals by GPs classified by different GP characteristics or organizational factors revealed much variation, which suggested that the variation was at the level of individual GPs. Furthermore, the p chart for each GP separately; which yielded a fewer number of points out of control (outliers), with an average of 4 points. For 26 GPs, there was no points out of control, those GPs were slightly older than those having points out of control. Otherwise, there was no significant difference between them. The revised p chart for those 26 GPs together yielded a centerline of 9.7%, upper control limit of 12.0% and lower control limit of 7.4%. Those limits were in good agreement with the limits specified by HIO; they can be suggested to be the new specification limits after some training programs. PMID:17265609

    The total amount of solid waste generated in Alexandria is 2820 tons/d which increases to 3425 tons/day during summer. In the past, 77% of the collected solid wastes was open dumped. The open dumping sites did not have the minimum requirements for pollution control. Following the exacerbation of the problem, the Alexandria Governorate contracted a company to carry out the solid waste management. The contracted company transferred 75% of the daily generated solid wastes to a new constructed sanitary lanfill. The site receives a daily average of 1910 tons. The landfilling is performed by trench method in the form of cells. The produced leachate is discharged into two lined aerated lagoons. The biogas formed from biodegradation of landfilled solid wastes is burned and the produced heat is used for drying the lagoons leachate. The remaining residues are relandfilled. The study aims at assessment of the solid waste sanitary landfill leachate characterization and its impacts on the groundwater. The analysis of the collected data confirms that leachates from the landfill are severely contaminated with organics, salts, and heavy metals. The fluctuations in concentration levels of the different parameters were attributed to aging and thickness of waste layers, stage of decomposition, and re-landfilling of the concentrated residues from the drying lagoons. The concentrations of NH4-N (600 mg/l) indicated that the process of stabilization was still in the initial stages and attributed to the compaction process. The high BOD5 results (28,833 mg/l) indicated that the process of stabilization was in the initial stages which were very slow. The high COD results (45,240 mg/l) can be attributed to the compaction of the wastes which also retards the degradation of the solid wastes. The BOD and COD values indicated clearly severe contamination. The BOD5/COD ratio measured in the current study (0.64) indicated that the leachate of the present study was biodegradable and unstabilized

    A stratified random sample of 1000 women with proportionate allocation according to district of residence was taken from normal females living in Alexandria, Egypt, and attending family planning centers in order to understand social-pathological changes in the vaginal flora of oral contraceptive (OC) users. Cases were examined over 18 months, and all cases were given a combined OC. Bacteriology and pH changes in vaginal flora were determined after 18 months. Results of the bacteriological examination revealed a positive correlation between those having a vaginal discharge and pH above 5, mixed infection, and illiteracy. As the duration of pill use increased, so did the incidence of monilla, staphylococcus aureus, anaerobic streptococci, gram negative bacilli, trichomonas vaginalis, and hemophilus vaginalis, whereas lactobacilli decreased. Duration of pill use also corresponded to increase in vaginal pH. Longer duration of OC use, practice of bad hygiene, and illiteracy were factors associated with an alkaline pH, changed pattern of vaginal flora, and greater susceptibility to infection by staph aureus and E. coli.

    Swimming pools have been identified as posing some public health risks to users due to either bacterial or chemical contamination. As a result, maintaining good swimming pool water quality is an important issue in preventing health risks for bathers. This study aimed to evaluate the bacteriological quality of some swimming pools in Alexandria and to investigate the prevalence of Staphylococcus aureus (S. aureus) in water samples. A total of 120 water samples from 10 swimming pools were collected. Bacteriological analysis included heterotrophic plate count (HPC) using pour plate method; enumeration of total coliforms (TC), Escherichia coli (E. coli) and S. aureus by membrane filtration technique. Antimicrobial susceptibility testing was performed on isolated S. aureus. Residual chlorine and pH were measured at swimming pools side. HPC was the least complying microbial parameter, followed by TC. S. aureus was recovered from 18 samples; 9 isolates were methicillin resistant S.aureus (MRSA), compared to E. coli that was detected in 7 samples. HPC and TC showed statistically significant correlations with all investigated parameters. In conclusion, the examined pools showed poor quality regarding all examined parameters collectively according to the Egyptian guidelines, which necessitates implementation of proper measures to ensure safer environment in swimming pools.

    Toxoplasma gondii is an opportunistic parasite with neurotropic characteristics that can mediate neurodevelopmental disorders, including mental, behavioral and personality aspects of their hosts. Therefore, the seroprevalence of anti-Toxoplasma antibodies has been studied in patients with different neurological disorders from different localities. On searching online databases, however, we could not find published studies on the seroprevalence of anti-Toxoplasma antibodies among patients with neurodevelopmental disorders in Egypt. Therefore, the present preliminary study was conducted to determine the serological profile of T. gondii infection among patients with non-schizophrenic neurodevelopmental disorders in Alexandria, Egypt. Data and blood samples were collected from 188 patients recruited for the study from four mental rehabilitation centers in the period from July 2014 to March 2015. The overall seropositivity rates of IgM and IgG among patients were 16.5% (31/188) and 50.0% (94/188), respectively. Of the studied patients' characteristics, only age was significantly associated with anti-Toxoplasma IgG seropositivity, with older patients being about twice more likely exposed to infection. However, no statistically significant association was found with IgM. In addition, seropositivity of anti-Toxoplasma IgG, but not IgM, was significantly associated with non-schizophrenic neurodevelopmental disorders; however, neither IgG nor IgM showed a significant association with cognitive impairment as indicated by the intelligence quotient scores.

    This study investigated the microbial causes of diarrheal disease among U.S. troops deployed near Alexandria, Egypt, during October 1995. Bacterial causes associated with 19 cases of diarrhea included: enterotoxigenic Escherichia coli (ETEC), 42% (21% heat-stable, 11% heat-labile, and 11% heat-stable/ heat-labile producers); enteropathogenic E. coli (5.3%); and enteroadherent E. coli (42%). Four cases of diarrhea were associated with enteroaggregative E. coli based on probe analysis for enteroaggregative heat-stable enterotoxin 1. Protozoan causes included; Entamoeba histolytica (11%), E. hartmanni (5%), E. nana (5%), Blastocystis hominis (5%), Chilomastix mesnili (11%), Dientamoeba fragilis (5%), Entamoeba coli (5%), and Cryptosporidium (5%). Shigella, Aeromonas, Plesiomonas, Vibrio, Campylobacter, and Salmonella were not detected. Of the eight ETEC cases, one was colonization factor antigen (CFA)/I only, one was both CFA/I and CFA/III, three were CFA/II, two were CFA/IV, and two were CFA-negative. Antibiograms of the ETEC and enteroadherent E. coli strains showed that all isolates were susceptible to norfloxacin, ciprofloxacin, and nalidixic acid but resistant to ampicillin, tetracycline, chloramphenicol, and sulfamethoxazole.

  1. Alexandria fluidized-bed process development unit: cold-mode testing

    SciTech Connect

    1981-02-01

    The objectives of the current test program include: validation of predictions from the Massachusetts Institute of Technology (MIT) Coal Atmospheric Fluidized Bed Combustor System Model; experimental studies supporting AFBC process developments; and the collection of transient data for process control design. This topical report summarizes results from cold mode testing, i.e., experiments performed without combustion for MIT Model verification. During these tests, sulfated limestone (generated from normal AFBC operations) was fluidized with air at temperatures ranging from 80 to 500/sup 0/F in the 3' x 3' (nominal) size PDU at Alexandria, VA. The MIT Model predictions tested include: slumped bed height, minimum fluidization velocity, and expanded bed height. In all cases, there were large discrepancies between the Model predictions and corresponding experimental results. Other results obtained included solids size distribution and particle size profiles in the bed. Size distribution was adequately modeled by the Rosin-Rammler equation. No transient process data was collected due to hardware problems with the Data Acquisition System. Tests were also performed to determine the effect of maldistribution of air, caused by leaks in the air distributor, on experimental results. The data indicated that effects of these leaks seemed to be undetectable.

  2. Studing some water quality parametres using remote sensing techniques in the Eastern Harbor, Alexandria, Egypt

    The environmental problems of Alexandria have grown rapidly in recent decades, in proportion to the growth in population and population density, as well as to the urban and industrial development. The rate of development has accelerated considerably since the turn of the century. A daily volume of more than one million cubic meters of mixed sewage water is drained from the city. About one third of this is disposed of without any treatment, into the Eastern and Western Harbors and their surroundings. The Qait Bey outfall, located a few hundred meters from the recently surveyed Pharos site, releases 200,000 m3 of waste water per day. The Eastern Harbor is the recipient of 7 outfalls. This semi-closed harbor remains permanently turbid, and water visibility is drastically reduced. Some studies were made in Eastern Harbor region, but special studies are needed to understand the variability of the water quality (Total suspended matter (TSM), transparency and chlorophyll) . Therefore, the objective of this study is to use the remote sensing application on marine environment for detecting transparency, total suspended matter and chlorophyll and its influences on Eastern Harbor based on the remote sensing techniques. Remote sensing techniques assess water quality in Eastern Harbor with special algorithms to extract all possible information using different satalittes images for the four seasons during 2006. The resulted images have been compared with ground measurements and showed high agreement significant relation between them. Eastern Harbor area are very closed and the harbor prevents the renew of water, so the transparency had been decreased while TSM and chlorophyll have been increased.

    The present work is a retrospective study designed to examine the assumption that emergency arrivals at the Sporting Students' Hospital in Alexandria follow a Poisson distribution. Data about all arrivals at the emergency room (ER) for the year, 2000 (43076 arrivals) was extracted from the records of the emergency department and classified by age, sex, school, reason for visit, date and time of visit. Data analysis revealed that 12.9% of the total arrivals indicated hospital admission either to the inpatient units (12.5%) or the ICU (0.4%). Goodness of fit test showed that admissions to the ICU fit the Poisson distribution but those admitted to the inpatient units did not follow the assumed distribution. However the latter group did not fit exactly the normal distribution which indicated that deviance from the Poisson is due to the large mean non-elective admissions (14.74% per day). Hence the Poisson assumption is not excluded as the inpatient emergency admissions are still randomly distributed and independent. Univariate and multivariate Poisson regression of the daily emergency admissions gave another clue to the goodness of fit of emergency admissions to the Poisson process. Regression analysis showed significantly higher loge number of emergency admissions among the age group 12 or more, male students, medical conditions in contrast to injuries, governmental schools, and at 04:00-11:59 pm in contrast to midnight to 07:59 am. Results of the present study indicated the random nature of demand for emergency admission which affects use of bed stock. A prospective study of these admissions on daily basis is needed.

    We assessed the food safety knowledge and food handling practices of 23 food handlers in 2 hospitals in Alexandria, Egypt [Gamal Abdel Nasser (GAN) and Medical Research Institute (MRI)] before and after a food safety training programme, and also the bacteriological quality of patient meals and kitchen equipment. There was a significant improvement in all knowledge-associated parameters except for personal hygiene in GAN. There was an improvement in the food safety practices in both hospitals. The bacteriological quality of most patient meals and food preparation surfaces and utensils improved after training. The bacteriological quality of patients' meals served in GAN was generally better than that in MRI. PMID:19166178

    Although all professionals oppose abusive physical punishment, nonabusive physical punishment is still controversial. The aim of the present study was (i) to determine parents' behavior regarding the discipline of their children using corporal punishment or other alternative disciplinary methods, (ii) to identify the different associated factors for corporal punishment, and (iii) to determine the association between exposure of the child to corporal punishment and his or her psychosocial well-being. A representative sample of 400 fifth-grade primary school children and their mothers were subjected to a cross-sectional survey. Mothers were subjected to a questionnaire to assess their behavior on corporal punishment and other disciplinary methods. The children were subjected to Coopersmith Self-Esteem Inventory to assess their self-esteem, and a questionnaire to assess their relationship with others. About three-quarter of children (76.3%) were corporally punished, and about half of them (46.2%) were punished on sites other than the extremities or buttocks. In 59.3% of them the frequency of the punishment ranged from once or twice/week to more than once/day, and it left marks in about 20%. Other disciplinary methods used by mothers were yelling/insulting (43.5%), taking away a toy or privilege (39.3%), discussing/explaining (9.5%), and time out (2.8%). The significant predictors of mothers' use of corporal punishment were male gender of the child (p < 0.01), rural origin of the father (p= 0.02), the mother's bad history of rearing experience (p < 0.01), and poor interparental relationship (p= 0.02). The relation between corporal punishment of children and their self-esteem was not statistically significant; however, corporally punished children scored lower on their relationship with others than noncorporally punished ones (Z= 2.60, p < 0.05). Corporal punishment is a widespread disciplinary method in Alexandria. The use of corporal punishment could have adverse

    Stanley, J.-D.; Bernhardt, C.E.

    2010-01-01

    Pollen and microscopic charcoal examined in Holocene sediment core samples record major environmental modifications affecting Alexandria's Eastern Harbor through time. We assess whether such changes on Egypt's coastal margin were influenced primarily by natural, or natural plus human, or primarily human factors. We focus on (1) the times when pollen assemblages and microscopic charcoal content changed in the core, (2) how they changed, and (3) why this occurred. The analysis takes into account the core's stratigraphy, regional climate variability, human history, and local archaeological record. Four pollenmicroscopic charcoal zones are identified. The earliest change occurred at ca. 6000 YBP, during Egypt's earlier Predynastic (Neolithic) period, coinciding with a lithologic break from sand to muddy sand. Pollen during this time indicates a transition to a much drier climate rather than effects of human activity. The second change in pollen occurred 3600-2900 YBP, during a period of continued aridity with no lithologic variation in this core interval. Pollen (cereal taxa, agricultural weeds, grape) and a sharp increase in microscopic charcoal indicate that human activity became prevalent at least 700 y before Alexander the Great's arrival in this region, and these results highlight the transition from a largely natural climatecontrolled environment to one influenced by both climate and anthropogenic activity. The third shift up-core in pollen assemblages is dated at ca. 2300 YBP, at the boundary between a sand and mud unit. It coincides with construction by the Ptolemies of the Heptastadion between Alexandria and Pharos Island. From this time onward, harbor sediment in the nearly enclosed catchment basin indicates a near-continuous record of dominant proximal human activity. ?? 2010 Coastal Education and Research Foundation.

    The paper presents the main results of the implementation of the Radioastron Early Science Program. Interferometric responses (fringes) were obtained for all types of studied radio sources (quasars, pulsars and cosmic masers) and in all ranges of wavelengths (from meter to centimeter range) with large spaceground baselines. Such measurements have provided a record angular resolution, in some cases reaching several tens of microseconds of arc. This brings unique scientific results concerning the nature of the processes occurring in the vicinity of the supermassive black holes, the structure of the interstellar plasma inhomogeneities and dynamics of compact objects in star-forming regions.

    scientific literature. The criteria were distributed among three main categories for each condition: The availability and characteristics of the screening test;The availability and complexity of diagnostic services; andThe availability and efficacy of treatments related to the conditions. A survey process utilizing a data collection instrument was used to gather expert opinion on the conditions in the first tier of the assessment. The data collection format and survey provided the opportunity to quantify expert opinion and to obtain the views of a diverse set of interest groups (necessary due to the subjective nature of some of the criteria). Statistical analysis of data produced a score for each condition, which determined its ranking and initial placement in one of three categories (high scoring, moderately scoring, or low scoring/absence of a newborn screening test). In the second tier of these analyses, the evidence base related to each condition was assessed in depth (e.g., via systematic reviews of reference lists including MedLine, PubMed and others; books; Internet searches; professional guidelines; clinical evidence; and cost/economic evidence and modeling). The fact sheets reflecting these analyses were evaluated by at least two acknowledged experts for each condition. These experts assessed the data and the associated references related to each criterion and provided corrections where appropriate, assigned a value to the level of evidence and the quality of the studies that established the evidence base, and determined whether there were significant variances from the survey data. Survey results were subsequently realigned with the evidence obtained from the scientific literature during the second-tier analysis for all objective criteria, based on input from at least three acknowledged experts in each condition. The information from these two tiers of assessment was then considered with regard to the overriding principles and other technology or condition

    The Nile Delta is one of the most complex, fragile and densely populated landscapes. It has suffered from abrupt environmental changes including sea level rise, sea water intrusion, and dramatic drawdown in groundwater levels due to severe pumping. The western part of Nile Delta's coast, from Alexandria to Marsa Matruh Governorates, is considered as one of the most vulnerable regions in Nile Delta. Environmentally complicated risks on water and soil coincide with suffering from strategic management problems. The general lack of studies linking sea level rise with socioeconomic impact cause large uncertainties. Such impacts became very critical recently, as subsidence and successive step sliding in the northern coast cause catastrophic disasters in areas with high population and socio-economic importance. Western Coast of Nile Delta is characterized by a succession of limestone and oolitic limestone which is extremely fragile and vulnerable to degradation in addition to dissolution by saline water. This study deals with studying the effect of global warming, sea level rise and severe pumping on the studied area. Examples will be given for soil degradation, subsidence, surface sliding, creeps successive step sliding, and sinkholes due to dissolving and fracturing of the limestone plateau.

    Leafy green vegetables, a popular and an indispensable ingredient of the daily menus of Egyptians' diets, currently presents a great concern in terms of microbiological hazards. To the best of our knowledge, this is the first report that provides scientific evidence for prevalence of shiga-toxigenic Escherichia coli (STEC) in leafy greens sold at open air local retail markets and superstores in the Egyptian environment. A total of 486 conventional and organic leafy green samples that are eaten raw were collected from different areas in Alexandria, evaluated for total E. coli counts (ECCs), and screened for E. coli O157:H7 using conventional and molecular methods. Recovery of E. coli (≥10(2)CFU/g) from all studied types of leafy greens was indicative of fecal contamination. Total ECCs in conventional samples ranged from 5.47 to 2.56 log CFU/g. Based on their inability to ferment sorbitol on CT-SMAC media, 26 presumptive E. coli O157 isolates were detected in 71.4% (270/378) of the studied conventional samples. From all studied organic samples, only 2 types (organic cabbage and parsley, 16.7%) were contaminated with presumptive E. coli O157. All 28 isolates were further serotyped as E. coli O157 by latex agglutination test, and biochemically confirmed as E. coli. Multiplex PCR assays confirmed the ability of 21.4% (6/28) of the E. coli O157 strains to produce shiga-toxins (Stxs), and their virulence markers were as follows: stx1, 66.6% (4/6); stx2, 50% (3/6); stx1/stx2, 16.7% (1/6); eaeA, 83.3% (5/6); and hlyA, 16.7% (1/6). Only 2 strains recovered from conventional and organic parsley could possibly be classified as E. coli O157:H7 based on the presence of stx-genes (either stx1 or stx2 or both). Results of the present research highlight that high E. coli loads, together with recovery of STEC O157 isolates could pose serious health risks to the produce consumers. This emphasizes the urgent need for health authorities to value and utilize the existing knowledge to

    Infants are most precious part of nation's life. Infant health is a reflection of the health of the mother and it gives an indication of the health of the adult population of the future. The present work was designed to study the health and nutritional status of infants in Karmouz area in Alexandria as well as the effect of breast feeding practices on the health status of infants. Accordingly, a house to house survey was conducted through cluster sampling technique. The total sample amounted to 396 mothers and 409 infants. Data were collected about infants health status and their feeding practices. Weight and length were measured for all infants. Stool samples were collected and examined. The results revealed that 55.3% of infants had acute respiratory tract infections (ARI); 16.4% had bronchitis and 4.9% had pneumonia, 44% of the infants suffered from diarrhea, 13.2% were infected with parasites, Gardia lamblia was the most commonly found parasite (9.0%). High proportion of infants was found to be stunted (22.7%), 8.6% were wasted and 7.6% were underweight, 40.3% of mothers were in partial practice level. Infants below six months of age who received solid foods at three months or less had a significantly higher percentage of diarrhea (70.6%) compared to 51.5% among those of late weaning (four months or later). The diarrhea was significantly more common among infants aged 12 - < 18 months with about two times of risk relative to those aged < 6 months. A significantly higher risk of diarrhea was found for infants of bottle--or complementary feeding (OR = 2.05, 2.07 respectively, model X2 = 9.71, P < 0.01), in addition the protective effect of breast feeding persisted after adjustment of confounders by multiple logistic regression. High proportion of mothers (63.8%) continued to breast-feed their babies during diarrheal episodes. On the other hand breast-feeding was not significantly protective against the acute respiratory tract infection. Stunting of the infants

    The present work was planned to study morbidity pattern and nutritional status of a group of healthy new borns in a rural area near Alexandria (Abbis II, VIII villages) through a prospective follow up approach. Eighty two infants were followed up for 12 months. Each infant was subjected to 15 visits within the first year of life. Morbidity was recorded either from mother's history, records from rural health centres or detected by the researcher and expressed as morbidity risk exposures based on a tested scoring system. Anthropometric standards issued by WHO were used to classify the children's length for age, weight for age and weight for length in terms of a cut off point of 2 SD below the median of that of the reference. Gomez classification was used to diagnose undernutrition and Waterlow system was used to diagnose growth stunting. Socioeconomic status of infants' families was also assessed. Results indicated a high prevalence of morbidity risk exposure, growth retardation and under nutrition with a tendency for gradual increase towards the end of the follow up. The results also proved that diarrheal diseases were still the most common illness among infants followed by respiratory tract infections. Investigation of the effects of socioeconomic status on morbidity risk exposure proved its significance at the end of the follow up. The results also illustrated a significant effect of morbidity risk exposure on the nutritional status at the end of the first year. PMID:1800623

    This is a pioneer study in Egypt that provides some assessment of the microbiological quality of conventional and organic leafy green vegetables that constitute an essential component of the Egyptians' daily diet. A total of 380 samples of unpackaged whole conventional and 84 packaged whole organic leafy greens were collected from retail markets in Alexandria, and analyzed for total aerobic mesophilic count (AMC) and total E. coli count (ECC) using the standard spread plate method. Mean AMC values for organic samples were statistically less (p < 0.05) than those of the corresponding conventional samples. Conventional radish and organic parsley samples had the highest AMC of 7.17 and 7.68 log CFU/g respectively, while conventional green cabbage and organic basil had the lowest AMC of 3.63 and 3.23 log CFU/g respectively. The presence of E. coli in 100% of the studied leafy greens was indicative of potential fecal contamination, in view of open and unhygienic environmental and unsanitary handling conditions, as leafy green items are available for sale by street-vendors. Unsatisfactory AMC and ECC levels encountered in the studied samples, warrant future investigations to determine the potential prevalence of foodborne pathogens, and to identify sources of dominating microorganisms, which could make a contribution to the field of food safety PMID:25115119

    Approximately 10,000 gal of spilled gasoline and unknown amounts Of trichloroethylene and benzene were discovered at the US Army`s Cameron Station facility. Because the base is to be closed and turned over to the city of Alexandria in 1995, the Army sought the most rapid and cost-effective means of spill remediation. At the request of the Baltimore District of the US Army Corps of Engineers, Argonne conducted a pilot-scale study to determine the feasibility of vapor extraction and bioventing for resolving remediation problems and to critique a private firm`s vapor-extraction design. Argonne staff, working with academic and private-sector participants, designed and implemented a new systems approach to sampling, analysis and risk assessment. The US Geological Survey`s AIRFLOW model was adapted for the study to simulate the performance of possible remediation designs. A commercial vapor-extraction machine was used to remove nearly 500 gal of gasoline from Argonne-installed horizontal wells. By incorporating numerous design comments from the Argonne project team, field personnel improved the system`s performance. Argonne staff also determined that bioventing stimulated indigenous bacteria to bioremediate the gasoline spin. The Corps of Engineers will use Argonne`s pilot-study approach to evaluate remediation systems at field operation sites in several states.

    Universe Awareness (UNAWE) is an educational programme coordinated by Leiden University that uses the beauty and grandeur of the Universe to encourage young children, particularly those from an underprivileged background, to have an interest in science and technology and foster their sense of global citizenship from the earliest age.UNAWE's twofold vision uses our Universe to inspire and motivate very young children: the excitement of the Universe provides an exciting introduction to science and technology, while the vastness and beauty of the Universe helps broaden the mind and stimulate a sense of global citizenship and tolerance. UNAWE's goals are accomplished through four main activities: the coordination of a global network of more than 1000 astronomers, teachers and educators from more than 60 countries, development of educational resources, teacher training activities and evaluation of educational activities.Between 2011 and 2013, EU-UNAWE, the European branch of UNAWE, was funded by the European Commission to implement a project in 5 EU countries and South Africa. This project has been concluded successfully. Since then, the global project Universe Awareness has continued to grow with an expanding international network, new educational resources and teacher trainings and a planned International Workshop in collaboration with ESA in October 2015, among other activities.

    According to some new discoveries at Tap-Osiris Magna temple (West of Alexandria), there is potentiality to uncover a remarkable archeological finding at this site. Three years ago many significant archeological evidences have been discovered sustaining the idea that the tomb of Cleopatra and Anthony may be found in the Osiris temple inside Tap-Osiris Magna temple at a depth from 20 to 30 m. To confirm this idea, PHASE I was conducted in by joint application of Ground Penetrating Radar “GPR”, Electrical Resistivity Tomography “ERT” and Magnetometry. The results obtained from PHASE I could not confirm the existence of major tombs at this site. However, small possible cavities were strongly indicated which encouraged us to proceed in investigation of this site by using another geophysical approach including Very Low Frequency Electro Magnetic (VLF-EM) technique. VLF-EM data were collected along parallel lines covering the investigated site with a line-to-line spacing of 1 m. The point-to-point distance of 1 m along the same line was employed. The data were qualitatively interpreted by Fraser filtering process and quantitatively by 2-D VLF inversion of tipper data and forward modeling. Results obtained from VLF-EM interpretation are correlated with 2-D resistivity imaging and drilling information. Findings showed a highly resistive zone at a depth extended from about 25-45 m buried beneath Osiris temple, which could be indicated as the tomb of Cleopatra and Anthony. This result is supported by Fraser filtering and forward modeling results. The depth of archeological findings as indicated from the geophysical survey is correlated well with the depth expected by archeologists, as well as, the depth of discovered tombs outside Tap-Osiris Magna temple. This depth level has not been reached by drilling in this site. We hope that the site can be excavated in the future based on these geophysical results.

  14. Profiling monoterpenol glycoconjugation in Vitis vinifera L. cv. Muscat of Alexandria using a novel putative compound database approach, high resolution mass spectrometry and collision induced dissociation fragmentation analysis.

    In this work we present a novel approach for the identification of plant metabolites using ultrahigh performance liquid chromatography coupled to accurate mass time-of-flight mass spectrometry. The workflow involves developing an in-house compound database consisting of exact masses of previously identified as well as putative compounds. The database is used to screen accurate mass spectrometry (MS) data to identify possible compound matches. Subsequent tandem MS data is acquired for possible matches and used for structural elucidation. The methodology is applied to profile monoterpene glycosides in Vitis vinifera cv. Muscat of Alexandria grape berries over three developmental stages. Monoterpenes are a subclass of terpenes, the largest class of plant secondary metabolites, and are found in two major forms in the plant, "bound" to one or more sugar moieties or "free" of said sugar moieties. In the free form, monoterpenes are noted for their fragrance and play important roles in plant defense and as attractants for pollinators. However, glycoconjugation renders these compounds odorless, and it is this form that the plant uses for monoterpene storage. In order to gain insight into monoterpene biochemistry and their fate in the plant an analysis of intact glycosides is essential. Eighteen monoterpene glycosides were identified including a monoterpene trisaccharide glycoside, which is tentatively identified here for this first time in any plant. Additionally, while previous studies have identified monoterpene malonylated glucosides in other grapevine tissue, we tentatively identify them for the first time in grape berries. This analytical approach can be readily applied to other plants and the workflow approach can also be used for other classes of compounds. This approach, in general, provides researchers with data to support the identification of putative compounds, which is especially useful when no standard is available. PMID:26320795

    Structured packing use in fluid catalytic cracker (FCC) main fractionators significantly impacts unit pressure profile. Unit pressure balance links the FCC main fractionator, reactor, regenerator, air compressor and wet gas compressor. Unit pressure balance should be viewed as a design variable when evaluating FCC unit revamps. Depending upon limitations of the particular FCC unit, capacity increases of 12.5% to 22.5% have been achieved without modifications to major rotating equipment, by revamping FCC main fractionators with structured packing. An examination of three FCC main fractionator revamps show improvements to pressure profiles and unit capacity. The three revamps described included a wet gas compressor volume limit; an air blower limitation; and a wet gas compressor motor limitation.

    1986-01-01

    Traditionally the views on the cosmic environent have been based on observations in the visual octave of the electromagnetic spectrum, during the last half-century supplemented by infrared and radio observations. Space research has opened the full spectrum. Of special importance are the X-ray-gamma-ray regions, in which a number of unexpected phenomena have been discovered. Radiations in these regions are likely to originate mainly from magnetised cosmic plasmas. Such a medium may also emit synchrotron radiation which is observable in the radio region. If a model of the universe is based on the plasma phenomena mentioned it is found that the plasma universe is drastically different from the traditional visual universe. Information about the plasma universe can also be obtained by extrapolation of laboratory experiments and magnetospheric in situ measurements of plasmas. This approach is possible because it is likely that the basic properties of plasmas are the same everywhere. In order to test the usefulness of the plasma universe model it is applied to cosmogony. Such an approach seems to be rather successful. For example, the complicated structure of the Saturnian C ring can be accounted for. It is possible to reconstruct certain phenomena 4 to 5 billions of years ago with an accuracy of better than 1%.

    The connectedness locus in the parameter space of quadratic polynomials is called the Mandelbrot set. A good combinatorial model of this set is due to Thurston. By definition, the principal hyperbolic domain of the Mandelbrot set consists of parameter values, for which the corresponding quadratic polynomials have an attracting fixed point. The closure of the principal hyperbolic domain of the Mandelbrot set is called the main cardioid. Its topology is completely described by Thurston's model. Less is known about the connectedness locus in the parameter space of cubic polynomials. In this paper, we discuss cubic analogues of the main cardioid and establish relationships between them.

    The characterization of the molecular mechanisms involved in development and progression of melanoma could be helpful to identify the molecular profiles underlying aggressiveness, clinical behavior, and response to therapy as well as to better classify the subsets of melanoma patients with different prognosis and/or clinical outcome. Actually, some aspects regarding the main molecular changes responsible for the onset as well as the progression of melanoma toward a more aggressive phenotype have been described. Genes and molecules which control either cell proliferation, apoptosis, or cell senescence have been implicated. Here we provided an overview of the main molecular changes underlying the pathogenesis of melanoma. All evidence clearly indicates the existence of a complex molecular machinery that provides checks and balances in normal melanocytes. Progression from normal melanocytes to malignant metastatic cells in melanoma patients is the result of a combination of down- or up-regulation of various effectors acting on different molecular pathways.

  10. Aquarius main structure configuration

    NASA Astrophysics Data System (ADS)

    Eremenko, A.

    The Aquarius/SAC-D Observatory is a joint US-Argentine mission to map the salinity at the ocean surface. This information is critical to improving our understanding of two major components of Earth's climate system - the water cycle and ocean circulation. By measuring ocean salinity from space, the Aquarius/SAC-D Mission will provide new insights into how the massive natural exchange of freshwater between the ocean, atmosphere and sea ice influences ocean circulation, weather and climate. Aquarius is the primary instrument on the SAC-D spacecraft. It consists of a Passive Microwave Radiometer to detect the surface emission that is used to obtain salinity and an Active Scatterometer to measure the ocean waves that affect the precision of the salinity measurement. The Aquarius Primary Structure houses instrument electronics, feed assemblies, and supports a deployable boom with a 2.5 m Reflector, and provides the structural interface to the SAC-D Spacecraft. The key challenge for the Aquarius main structure configuration is to satisfy the needs of component accommodations, ensuring that the instrument can meet all operational, pointing, environmental, and launch vehicle requirements. This paper describes the evolution of the Aquarius main structure configuration, the challenges of balancing the conflicting requirements, and the major configuration driving decisions and compromises.

    2015-01-01

    A developmental Main Oxidizer Valve (MOV) was designed by NASA-MSFC using additive manufacturing processes. The MOV is a pneumatically actuated poppet valve to control the flow of liquid oxygen to an engine's injector. A compression spring is used to return the valve to the closed state when pneumatic pressure is removed from the valve. The valve internal parts are cylindrical in shape, which lends itself to traditional lathe and milling operations. However, the valve body represents a complicated shape and contains the majority of the mass of the valve. Additive manufacturing techniques were used to produce a part that optimized mass and allowed for design features not practical with traditional machining processes.

    Violent behaviour among school students and its predictors were investigated. Selected children (2170) were requested to complete a self-administered questionnaire. Initiating violent assaults in the 18 months prior to the study was reported by 51.0% of boys and 20.9% of girls. Multivariate logistic regression analysis pointed to 16 predictive variables for violent behaviour; few were related to family background whereas the majority were related to the children themselves. Violent assaults were more likely to be initiated by boys and those who were dangerously daring and risk-takers, often fought verbally, threatened to attack others, were cruel to animals, disrupted class discipline, were truant from school or ran away from home and were disciplined by corporal punishment by their parents and their teachers. School-based prevention and intervention programmes addressing modifiable predictors should be considered. PMID:10793805

    Aneurysms of the left main coronary artery are exceedingly rare clinical entities, encountered incidentally in approximately 0.1% of patients who undergo routine angiography. The most common cause of coronary artery aneurysms is atherosclerosis. Angiography is the gold standard for diagnosis and treatment. Depending on the severity of the coexisting coronary stenosis, patients with left main coronary artery aneurysms can be effectively managed either surgically or pharmacologically. We herein report a case of left main coronary artery aneurysm in a 72-year-old man with a prior history of hypertension presenting to our hospital because of unstable angina. The electrocardiogram showed ST-segment depression and T-wave inversion in the precordial leads. All the data of blood chemistry were normal. Echocardiography showed akinetic anterior wall, septum, and apex, mild mitral regurgitation and ejection fraction of 45%. Coronary angiography revealed a saccular aneurysm of the left main coronary artery with significant stenosis in the left anterior descending, left circumflex, and right coronary artery. The patient immediately underwent coronary artery bypass grafting and ligation of the aneurysm. At six months’ follow-up, he remained asymptomatic. PMID:27403190

    1981-01-01

    A technical description of the space shuttle main engine controller, which provides engine checkout prior to launch, engine control and monitoring during launch, and engine safety and monitoring in orbit, is presented. Each of the major controller subassemblies, the central processing unit, the computer interface electronics, the input electronics, the output electronics, and the power supplies are described and discussed in detail along with engine and orbiter interfaces and operational requirements. The controller represents a unique application of digital concepts, techniques, and technology in monitoring, managing, and controlling a high performance rocket engine propulsion system. The operational requirements placed on the controller, the extremely harsh operating environment to which it is exposed, and the reliability demanded, result in the most complex and rugged digital system ever designed, fabricated, and flown.

  14. The main Aeromonas pathogenic factors.

    PubMed

    Tomás, J M

    2012-01-01

    The members of the Aeromonas genus are ubiquitous, water-borne bacteria. They have been isolated from marine waters, rivers, lakes, swamps, sediments, chlorine water, water distribution systems, drinking water and residual waters; different types of food, such as meat, fish, seafood, vegetables, and processed foods. Aeromonas strains are predominantly pathogenic to poikilothermic animals, and the mesophilic strains are emerging as important pathogens in humans, causing a variety of extraintestinal and systemic infections as well as gastrointestinal infections. The most commonly described disease caused by Aeromonas is the gastroenteritis; however, no adequate animal model is available to reproduce this illness caused by Aeromonas. The main pathogenic factors associated with Aeromonas are: surface polysaccharides (capsule, lipopolysaccharide, and glucan), S-layers, iron-binding systems, exotoxins and extracellular enzymes, secretion systems, fimbriae and other nonfilamentous adhesins, motility and flagella.

  16. Puzzling Snowballs: Main Belt Comets

    NASA Astrophysics Data System (ADS)

    Yang, Bin; Meech, Karen

    2015-03-01

    Main belt comets (MBCs) are a class of newly discovered objects that exhibit comet-like appearances and yet are dynamically indistinguishable from ordinary main belt asteroids. The measured size and albedo of MBCs are similar to those of classical comets. At present, six MBCs have been discovered, namely 133P/Elst-Pizarro, 176P/LINEAR, 238P/Read, P/2008 R1, P/La Sagra and P/2006 VW139. The total number of active MBCs is estimated to be at the level of a few hundreds (Hsieh & Jewitt, 2006). Several explanations for the activity of MBCs have been suggested. These include impact ejection, sublimation and rotational instability. However, since renewed activity has been observed in 133P and 238P at successive perihelion passages, the most likely explanation may be a thermally-driven process - e.g sublimation of exposed surface ice. Although the proximity of MBCs to the Sun (r ~ 3 AU) makes the survival of surface ice improbable, thermal models have shown that water ice is thermally stable under a regolith layer a few meters thick. The study of MBCs has recently been complicated by the discoveries of two asteroid collisional events (P/2010 A2 (LINEAR) and (596) Scheila) in 2010, where comet-like dust coma/tail have been attributed to recent impacts. If MBCs are indeed icy, they represent the closest and the third established reservoir of comets (after the Oort cloud and the Kuiper belt). As such, they may have been an important source of water for the Earth's oceans. I will review the current state of MBC studies, present the latest observational results and discuss possible mechanisms that could produce the observed activity. I will also talk about current and future space missions that are dedicated or closely related to MBC studies.

  17. Eternal Universe

    NASA Astrophysics Data System (ADS)

    Wetterich, C.

    2014-08-01

    We discuss cosmological models for an eternal Universe. Physical observables show no singularity from the infinite past to the infinite future. While the Universe is evolving, there is no beginning and no end—the Universe exists forever. The early state of inflation is described in two different, but equivalent pictures. In the freeze frame the Universe emerges from an almost static state with flat geometry. After entropy production it shrinks and "thaws" slowly from a "freeze state" with extremely low temperature. The field transformation to the second "big bang picture" (Einstein frame) is singular. This "field singularity" is responsible for an apparent singularity of the big bang. Furthermore, we argue that past-incomplete geodesics do not necessarily indicate a singularity or beginning of the Universe. Proper time ceases to be a useful concept for physical time if particles become massless. We propose to define physical time by counting the number of zeros of a component of the wave function. This counting is independent of the choice of coordinates and frames, and applies to massive and massless particles alike.

    Terrorism and threatening dictatorships are the main, man-made, dangers of our times. They are run by master demagogues, or, brain-washing manipulators. ----- Our next step in coping with terrorism is to counter master demagoguery. Therefore, supporting EDUCATION that would emphasize the most unifying (and the least controversial), yet, BASIC CIVIC RESPECT for lives of people in a civilian human society, is a priority everywhere on our planet. ----- At the same time we start facing mostly small, threatening, dictatorships, capable of producing weapons of mass destruction. Therefore, we have to try to contribute to developing systems of FREE ELECTIONS, controlling weapons of mass destruction, wherever such dangers exist. ----- In a foreseeable future, unfortunately, we are facing a danger even by orders of magnitude greater. We are facing a possibility of a mass-produced heavy accumulation of inter-continental nuclear missiles, on a computerized "push-button" control, by a very powerful (and, quite possibly, miscalculating, or, suicidal) dictator, dangerous to the very existence of humanity on our planet. Therefore, it is a historical urgency that such a technological power be under the control by a government of the people, by the people and for the people, based on a sufficiently reliable system of FREE ELECTIONS, wherever, on our planet, such a potential danger may originate.

  20. Main memory unit. [hybrid computers

    NASA Technical Reports Server (NTRS)

    1975-01-01

    The development of a main memory unit (MMU) for the space ultrareliable module computer (SUMC) model HTC is discussed. The design, fabrication, and test of basic memory modules (BMM) which were to be used in the design and construction of the MMU are described. The BMM was designed from state-of-the-art technologies which included large scale integration devices mounted and interconnected on a substrate to form a functional module to be utilized in the MMU development. A SUMC memory system design study is discussed which addressed itself to the BMM design and analysis to be conducted to determine the most efficient organization of the BMM in order to establish such modularity features as: word length expandability without redesign, high reliability, and fault tolerance. One MMU was designed, fabricated, tested, and delivered which will be electrical and mechanically compatible with the hybrid technology computer (HTC) model of the SUMC family of computers. The MMU will contain a storage capacity of 8196 36 bit words which includes a parity bit for each 8 bit byte of data.

  9. University lobbying

    NASA Astrophysics Data System (ADS)

    Richman, Barbara T.

    In the past year, an increasing number of individual academic institutions have lobbied in Congress for new science facilities funds thus circumventing the traditional peer review process of evaluating the merits of such facilities. As an attempt to stem this rising tide, the National Academy of Sciences (NAS) governing council and the Association of American Universities (AAU) recently and independently issued strong statements condemning lobbying by individual universities and enthusiastically supporting the peer review system.“Informed peer judgments on the scientific merits of specific proposals, in open competition, should be a central element in the awarding of all federal funds for science,” the NAS resolution stated. AAU, meanwhile, implored “scientists, leaders of America's universities, and members of Congress” to “refrain from actions that would make scientific decisions a test of political influence rather than a judgment on the quality of the work to be done.” Roughly 50 research institutions constitute AAU; the two AAU Canadian members did not vote on the consortium's statement.

  10. Case for an open universe

    Canuto, V.; Hsieh, S.-H.

    1980-01-01

    The determination of the geometrical structure of the universe through the magnitude-vs-redshift relation in standard cosmology has not been very successful, mainly because of the intrinsic insensitivity of the m-vs-z relation to a deceleration parameter, which determines the spatial curvature and therefore the geometry. By relaxing the assumption usually made, i.e., the identity of gravitational and atomic clocks, sufficient sensitivity is achieved. Existing observational evidence then leads one to conclude that the universe is open.

    The Purdue University group, including several thesis students, is working on a measurement of high-spin nuclear states at ATLAS. They use in-beam gamma-ray techniques to investigate several aspects of nuclear structure at high spin, testing the validity of shell-model calculations for high-spin-yrast states near Z = 50. The nuclei are produced via deep inelastic reactions, rather than with the more conventional fusion reactions. This technique allows the study of neutron-rich nuclei that cannot be studied by other means. The group is studying proton-rich nuclei with N{approximately}82 using the FMA and an electron spectrometer. Furthermore, D.

  9. As the nation goes, so goes Maine?

    PubMed

    Kilbreth, Elizabeth

    2014-06-01

    Historically, Maine has been a state with generous safety net programs and a track record of innovative efforts in health system reform, developed under the leadership of Democratic administrations and with frequent support from moderate Republicans. But the 2010 elections in Maine dramatically changed the political balance of power, anointing both a governor and a legislature ideologically at odds with the state's recent political past. Maine has become a bastion of resistance to the Patient Protection and Affordable Care Act, with a reduced Medicaid program, defunded state access initiative, and no state exchange. In addition, the state has adopted a laissez-faire approach to insurance market dysfunction. Using Maine as a case study of the shifts in national political mood, this article describes in broad brushstrokes Maine's history of health reform efforts and recent shift in political direction, and discusses some of the factors that contributed to the change.

    The Yeager Building was originally a two-story office building that has been renovated to a studio type building for artists, craftsmen, etc. All existing mechanical systems were removed, and three new gas fired split systems were installed to heat and cool the building. The first floor of the building consists primarily of studios and corridor space and is served by one air conditioning unit (11 rows cooling and 107,000 BTUH heating). The heating is assisted by a hot water heating coil (45,000 BTUH) in the supply duct which derives its energy from solar collectors mounted on the roof. The solar system also preheats the incoming domestic water before it enters the domestic water heater. The solar system was installed as indicated on the plans and specifications.

    2016-02-21

    This critical review focuses on the solution based chemical vapour deposition (CVD) of main group materials with particular emphasis on their current and potential applications. Deposition of thin films of main group materials, such as metal oxides, sulfides and arsenides, have been researched owing to the array of applications which utilise them including solar cells, transparent conducting oxides (TCOs) and window coatings. Solution based CVD processes, such as aerosol-assisted (AA)CVD have been developed due to their scalability and to overcome the requirement of suitably volatile precursors as the technique relies on the solubility rather than volatility of precursors which vastly extends the range of potentially applicable compounds. An introduction into the applications and precursor requirements of main group materials will be presented first followed by a detailed discussion of their deposition reviewed according to this application. The challenges and prospects for further enabling research in terms of emerging main group materials will be discussed. PMID:26446057

    Ceckler, W.H.

    1982-08-24

    By carrying out an in-depth study of the pressing behavior of one particular type of paper in the laboratory, pilot plant, and mill, a mechanistic computer model that can be used to predict mill press behavior based on laboratory compression tests on the paper was developed. As the data base was broadened by investigating other types of papermaking furnishes, it should eventually be possible to predict press behavior using only the model and generalized correlations based on these data. An important finding of this program is that direct comparisons between laboratory, pilot plant, and mill test results indicate that mill and pilot-plant press impulse is 14 to 22% as effective as laboratory press impulse. This efficiency was referred to as nip efficiency.

    There are two medical schools training doctors in Kenya: the Moi University established in 1984 and the University of Nairobi established in 1967. The University of Nairobi has so far produced the majority of Kenyan doctors. Both are public universities with the Government being the main financier. The increased demand for university education and the inability to meet these demands has led to the introduction of a system of training self-sponsored medical students alongside Government-subsidised students. One other public university has started a medical school. The pressure to increase the number of schools and students in the absence of increased resources poses a particular challenge to the country. PMID:20854156

  17. Guide to the Main Ring DO overpass

    SciTech Connect

    Turkot, F.

    1985-03-20

    The DO overpass is a modification of the beam orbit in Main Ring in order to better accommodate a Tevatron collider detector at DO. The orbit is moved up approx. 51 inches over most of the long straight section at DO, thus making the Main Ring the world's first non-planar proton synchrotron. A similar overpass, but with four times the displacement, is planned for the CDF detector at the BO straight section. The nominal separation between the beam orbit in the Main Ring and the orbit in the Tevatron is 25.5 inches. Early in the design study of a detector that would utilize the Tevatron is a anti pp collider, it was apparent that a larger separation at the detector was highly desirable. In 1981, Tom Collins proposed a specific lattice geometry in the Main Ring for achieving larger separation, called ''the screw beam''. His proposal has served as the basis for the design of both the BO and DO overpasses. The main purpose of this report is to describe in some detail the implementation of the DO overpass. Topics to be covered include: (a) geometry of the overpass orbit, (b) the new hardware in the tunnel, (c) the power supply system, (d) the control facility, (e) accelerator beam dynamics ramifications, and (f) commissioning experience. A secondary purpose is to provide a fairly complete ''bibliography'' to the sources of information on the overpass. 17 refs., 17 figs.

    1997-03-01

    The main structure is defined as the telescope mechanical structure including the drives, the encoder system, the hydrostatic bearing system and all those subsystems which make the system self standing safe and testable as an electromechanical system, with the exclusion of the velocity and position control loops. The main structure is now almost completely assembled in Milan. The tests of the main mechanical performances (dynamic and static) have been carried out to gather information at the earliest possible stage of the assembling activities. The drives and the hydrostatic bearing system have been tested concerning their functionality. This paper aims to summarize concisely the results of the tests, to compare them to the design calculations and to show some possible design changes which could improve the performances of the telescope.

  19. Main Coast Winds - Final Scientific Report

    SciTech Connect

    Jason Huckaby; Harley Lee

    2006-03-15

    The Maine Coast Wind Project was developed to investigate the cost-effectiveness of small, distributed wind systems on coastal sites in Maine. The restructuring of Maine's electric grid to support net metering allowed for the installation of small wind installations across the state (up to 100kW). The study performed adds insight to the difficulties of developing cost-effective distributed systems in coastal environments. The technical hurdles encountered with the chosen wind turbine, combined with the lower than expected wind speeds, did not provide a cost-effective return to make a distributed wind program economically feasible. While the turbine was accepted within the community, the low availability has been a negative.

    Sporny, Richard F.

    1990-01-01

    For the past two years the potential applications of computed tomography to the fabrication and overhaul of the Space Shuttle Main Engine were evaluated. Application tests were performed at various government and manufacturer facilities with equipment produced by four different manufacturers. The hardware scanned varied in size and complexity from a small temperature sensor and turbine blades to an assembled heat exchanger and main injector oxidizer inlet manifold. The evaluation of capabilities included the ability to identify and locate internal flaws, measure the depth of surface cracks, measure wall thickness, compare manifold design contours to actual part contours, perform automatic dimensional inspections, generate 3D computer models of actual parts, and image the relationship of the details in a complex assembly. The capabilities evaluated, with the exception of measuring the depth of surface flaws, demonstrated the existing and potential ability to perform many beneficial Space Shuttle Main Engine applications.

  1. Main-group elements as transition metals.

    PubMed

    Power, Philip P

    2010-01-14

    The last quarter of the twentieth century and the beginning decade of the twenty-first witnessed spectacular discoveries in the chemistry of the heavier main-group elements. The new compounds that were synthesized highlighted the fundamental differences between their electronic properties and those of the lighter elements to a degree that was not previously apparent. This has led to new structural and bonding insights as well as a gradually increasing realization that the chemistry of the heavier main-group elements more resembles that of transition-metal complexes than that of their lighter main-group congeners. The similarity is underlined by recent work, which has shown that many of the new compounds react with small molecules such as H(2), NH(3), C(2)H(4) or CO under mild conditions and display potential for applications in catalysis.

  2. A photoelectric lightcurve survey of small main belt asteroids

    NASA Technical Reports Server (NTRS)

    Binzel, R. P.; Mulholland, J. D.

    1983-01-01

    A survey to obtain photoelectric lightcurves of small main-belt asteroids was conducted from November 1981 to April 1982 using the 0.91- and 2.1-m telescopes at the University of Texas McDonald Observatory. A total of 18 main-belt asteroids having estimated dimaters under 30 km were observed with over half of these being smaller than 15 km. Rotational periods were determined or estimated from multiple nights of observation for nearly all of these yielding a sample of 17 small main-belt asteroids which is believed to be free of observational selection effects. All but two of these objects were investigated for very short periods in the range of 1 min to 2 hr using power spectrum analysis of a continuous set of integrations. No evidence for such short periods was seen in this sample. Rotationally averaged B(1,0) magnitudes were determined for most of the surveyed asteroids, allowing diameter estimates to be made. Imposing the suspected selection effects of photogaphic photometry on the results of this survey gives excellent agreement with the results from that technique. This shows that the inability of photographic photometry to obtain results for many asteroids is indeed due to the rotational parameter of those asteroids.

  3. Bunch coalescing in the Fermilab Main Ring

    Wildman, D.; Martin, P.; Meisner, K.; Miller, H.W.

    1987-03-01

    A new rf system has been installed in the Fermilab Main Ring to coalesce up to 13 individual bunches of protons or antiprotons into a single high-intensity bunch. The coalescing process consists of adiabatically reducing the h = 1113 Main Ring rf voltage from 1 MV to less than 1 kV, capturing the debunched beam in a linearized h = 53 and h = 106 bucket, rotating for a quarter of a synchrotron oscillation period, and then recapturing the beam in a single h = 1113 bucket. The new system will be described and the results of recent coalescing experiments will be compared with computer-generated particle tracking simulations.

    The Defense Meteorological Satellite Program (DMSP) launches and maintains a network of satellites to monitor the meteorological, oceanographic, and solar-terrestrial physics environments. In the past decade, geomagnetic field modelers have focused much attention on magnetic measurements from missions such as CHAMP, Ørsted, and SAC-C. With the completion of the CHAMP mission in 2010, there has been a multiyear gap in satellite-based vector magnetic field measurements available for main field modeling. In this study, we calibrate the special sensor magnetometer instrument on board DMSP to create a data set suitable for main field modeling. These vector field measurements are calibrated to compute instrument timing shifts, scale factors, offsets, and nonorthogonality angles of the fluxgate magnetometer cores. Euler angles are then computed to determine the orientation of the vector magnetometer with respect to a local coordinate system. We fit a degree 15 main field model to the data set and compare with the World Magnetic Model and Ørsted scalar measurements. We call this model DMSP-MAG-1, and its coefficients and software are available for download at http://geomag.org/models/dmsp.html. Our results indicate that the DMSP data set will be a valuable source for main field modeling for the years between CHAMP and the recently launched Swarm mission.

  14. Behavioral medicine in Teikyo University and Toho University.

    2016-01-01

    Behavioral medicine has increased in importance to become a promising field in medical education. The Teikyo University Graduate School of Public Health and Toho University School of Medicine were evaluated in terms of their educational emphasis on behavioral medicine. The Teikyo University Graduate School of Public Health has the following five core requirements, as in the global standards: behavioral medicine, biostatistics, epidemiology, occupational health, and health policy management. Behavioral medicine mainly encompasses psychology in normal populations, working as a gateway to the medical world among non-medical professionals who are interested in medicine. The Toho University School of Medicine aims to produce "good clinicians" who have a thorough knowledge, a deep sense of professional ethics, and a profound humanity to contribute to human welfare through medicine. In behavioral medicine here, systematic knowledge based on human behavior in medicine is taught from the first to sixth year. Psychosomatic physicians could be among the most optimal professionals for behavioral medicine because of the similarities between psychosomatic medicine and behavioral medicine. The establishment of a Center of Behavioral Medicine is a potential solution to tackle forthcoming medical problems, such as increasing medical costs and an aging society. We must focus on the importance of behavior change as a way for preventive medicine to connect hospitals and communities in Japan. PMID:26913061

  15. Jupiter's Main Ring/Ring Halo

    NASA Technical Reports Server (NTRS)

    1997-01-01

    A mosaic of four images taken through the clear filter (610 nanometers) of the solid state imaging (CCD) system aboard NASA's Galileo spacecraft on November 8, 1996, at a resolution of approximately 46 kilometers (28.5 miles) per picture element (pixel) along Jupiter's rings. Because the spacecraft was only about 0.5 degrees above the ring plane, the image is highly foreshortened in the vertical direction. The images were obtained when Galileo was in Jupiter's shadow, peering back toward the Sun; the ring was approximately 2.3 million kilometers (1.4 million miles) away. The arc on the far right of the image is produced when sunlight is scattered by small particles comprising Jupiter's upper atmospheric haze. The ring also efficiently scatters light, indicating that much of its brightness is due to particles that are microns or less in diameter. Such small particles are believed to have human-scale lifetimes, i.e., very brief compared to the solar system's age.

    Jupiter's ring system is composed of three parts - - a flat main ring, a lenticular halo interior to the main ring, and the gossamer ring, outside the main ring. The near and far arms of Jupiter's main ring extend horizontally across the mosaic, joining together at the ring's ansa, on the figure's far left side. The near arm of the ring appears to be abruptly truncated close to the planet, at the point where it passes into Jupiter's shadow. Some radial structure is barely visible across the ring's ansa (top image). A faint mist of particles can be seen above and below the main rings. This vertically extended 'halo' is unusual in planetary rings, and is probably caused by electromagnetic forces pushing the smallest grains out of the ring plane. Because of shadowing, the halo is not visible close to Jupiter in the lower right part of the mosaic. To accentuate faint features in the bottom image of the ring halo, different brightnesses are shown through color. Brightest features are white or yellow and the

In my spare time over the past few years I have taken the original files of the Main Ring Section, my own notes from that period, and various other collections of relevant paper, and arranged them in a set of 44 large loose leaf binders in chronological order. I call this set of volumes the 'Main Ring Chronological Archives'. In response to Phil's request I have recently skimmed through these records of the period and extracted a small subset of documents which relate to the specific questions that Phil is addressing: staffing. administration, and milestones.

  17. Orbital evolution of the main Uranian satellites

    NASA Astrophysics Data System (ADS)

    Verheylewegen, E.; Noyelles, B.

    2011-10-01

    Since Voyager 2 space mission, we know some properties of the main Uranian satellites (Miranda, Ariel, Umbriel, Titania, Oberon): on the one hand, we observe an important resurfacing of both Miranda and Ariel, and on the other hand some strangenesses in the orbital elements such as the anomalously high inclinaison of Miranda or the anomalously high eccentricity of Ariel. The aim of this study is to use some modern methods including advances in computing resources to revise some studies developed in the last 20 years (see for instance [1], [2], [3], [4]). We therefore consider a model of a n-body problem which takes into account of the mutual perturbations of the five main satellites and of the planet Uranus and meet/improve some previous results.

  18. Aftershock patterns and main shock faulting

    USGS Publications Warehouse

    Mendoza, C.; Hartzell, S.H.

    1988-01-01

    We have compared aftershock patterns following several moderate to large earthquakes with the corresponding distributions of coseismic slip obtained from previous analyses of the recorded strong ground motion and teleseismic waveforms. Our results are consistent with a hypothesis of aftershock occurrence that requires a secondary redistribution of stress following primary failure on the earthquake fault. Aftershocks followng earthquakes examined in this study occur mostly outside of or near the edges of the source areas indicated by the patterns of main shock slip. The spatial distribution of aftershocks reflects either a continuation of slip in the outer regions of the areas of maximum coseismic displacement or the activation of subsidiary faults within the volume surrounding the boundaries of main shock rupture. -from Authors

Established the theory of "exuberant yang and insufficient yin", Zhu set up the therapy of nourishing yin to decrease fire. In the late Ming dynasty, Zhao Xianke and Zhing Jingyue founded the warm - tonification school, Zhao's theory on vital gate exerted profound influence on the basic theory of later ages. At the turn of Ming - Qing dynasties, a Qiantang school was set up by Zhang Shuichen, Zhang Zhicong and Zhang Xijun, Zhang Zhi cong being the synthetizen. The Shao school of cold-disease refers mainly to the physicians in the shaoxin region who studied the warm heat disorders (especially damp - warm diseases) which was mature at the turn of Qing dynasty and the Republican period, whose influence remained until the 1980s.

    The report has been prepared under a Memorandum of Understanding between the U.S. Bureau of Mines, U.S. Department of the Interior, and the Maine Geological Survey for collecting information on all nonfuel minerals. The value of Maine's nonfuel mineral production in 1991 was $41.3 million, a $21.2 million decrease compared with that of 1990. Decreases in output and value were reported for most of the nonfuel minerals produced. The largest decreases in both production and value were for construction sand and gravel and dimension stone. Smaller decreases were estimated for both masonry and portland cement. Other mineral commodities produced in the State included common clay, gemstones, and peat. Perlite was shipped in from out-of-State and expanded at one plant in the State.

  1. Acadian dextral transpression in western Maine

    SciTech Connect

    Pollock, S.G. ); Marvinney, R.G. )

    1993-03-01

    Two groups of faults characterize the Acadian tectonic regime of northwestern Maine. The first group is largely dextral and reverse in nature and is represented by the Deep Pond (DPF) and Thrasher Peaks (TPF) faults in the Jackman area. The second is reverse in nature, and is represented by three faults in the Caucomgomoc Lake area. Taken together this fault system represents an Acadian dextral transpressive regime. Part of this regime includes an 11 km wide by 17 km long horst of Cambrian( ), Ordovician( ) and Late Silurian rocks in the Caucomgomoc Lake area. This horst is a part of a restraining bend. Associated with this bend is a deflection and rotation of the regional fault, fold axis and cleavage pattern. Orientations of these structures generally change from NE-SW in the Jackman area to N-S in the Caucomgomoc area. In westernmost Maine, the DPF and TPF both strike NE-SW, but the strikes rotate to ENE-WSW farther to the east in the Jackman area. The NW-dipping DPF separates Silurian rocks of the Frontenac Fm on the north from Devonian rocks of the Seboomook Group on the south. Foliation associated with Acadian folding dips moderately (30--50 degrees) near the DPF and major folds are overturned and verge toward the SE along its entire length in Maine. This contrasts sharply with the dominant upright, NW-verging folds and sleep foliation which characterizes the Acadian throughout northwestern Maine. The NW-dipping TPF separates Devonian rocks of the Seboomook Group on the north from Precambrian and Ordovician rocks of the Chain Lakes massif and Attean pluton, respectively, on the south. Along the TPF and DPF are kinematic indicators which suggest reverse and dextral components to movement.

    The Crew Exploration Vehicle Parachute Assembly System (CPAS) is being designed to land the Orion Crew Module (CM) at a safe rate of descent at splashdown with a cluster of two to three Main parachutes. The instantaneous rate of descent varies based on parachute fly-out angles and geometric inlet area. Parachutes in a cluster oscillate between significant fly-out angles and colliding into each other. The former presents a sub-optimal inlet area and the latter lowers the effective drag area as the parachutes interfere with each other. The fly-out angles are also important in meeting a twist torque requirement. Understanding cluster behavior necessitates measuring the Mains with photogrammetric analysis. Imagery from upward looking cameras is analyzed to determine parachute geometry. Fly-out angles are measured from each parachute vent to an axis determined from geometry. Determining the scale of the objects requires knowledge of camera and lens calibration as well as features of known size. Several points along the skirt are tracked to compute an effective circumference, diameter, and inlet area as a function of time. The effects of this geometry are clearly seen in the system drag coefficient time history. Photogrammetric analysis is key in evaluating the effects of design features such as an Over-Inflation Control Line (OICL), Main Line Length Ratio (MLLR), and geometric porosity, which are varied in an attempt to minimize cluster oscillations. The effects of these designs are evaluated through statistical analysis.

    The following ideas are widely accepted in Chile with respect to scientific activity: is carried out mainly in universities and science is considered a naturally university activity, that was developed in a period of more than 150 years by isolated individual efforts, c) it was transformed into an institutionalized activity at the universities after the university reform movement at the end of the 1960 decade, d) the activity is finally institutionalized in the country with the creation of the “Comisión Nacional de Investigatión Científica y Tecnológica, CONICYT (National Commission for Scientific and Technological Research) in 1967. This work presents preliminary findings showing that there are other institutional initiatives, different to the efforts from universities and directly dependent of the Chilean Government, in order to produce science and technology in Chile. This governmental initiatives start at the beginning of the Republic of Chile circa of 1810.

    Arbuzova, E. V.; Dolgov, A. D.

    2013-03-01

    Astronomical data in favor of cosmological acceleration and possible explanations of accelerated expansion of the universe are discussed. Main attention is paid to gravity modifications at small curvature which could induce accelerated cosmological expansion. It is shown that gravitating systems with mass density rising with time evolve to a singular state with infinite curvature scalar. The universe evolution during the radiation-dominated epoch is studied in the R 2-extended gravity theory. Particle production rate by the oscillating curvature and the back reaction of particle production on the evolution of R are calculated in one-loop approximation. Possible implications of the model for cosmological creation of non-thermal dark matter are discussed.

    This paper postulates a virtual universe and compares and contrasts its properties to that of our known physical universe. A particular attention is paid to the interface between the two and challenges for transition from one to the other. Also discussed is the relationship of the virtual universe to such entities and concepts as dark matter, black holes, time travel, speed of light, mass, gravity just to name just a few. The paper also discusses interface between us physical beings and temporary virtual beings and eventually ultra beings. It also tangentially discusses relationship between body, brain, mind of physical beings with that of virtual and ultra beings. The paper also discusses why virtual beings do not have the same limitations and capabilities as we do. The past, present, elsewhere and potential of physical and virtual universes is compared. Finally possible pathways to discovery of TOE (Theory of Everything) is hypothesized.

    Santoro, Robert J.; Merkle, Charles L.

    1999-01-01

    This document reports the experimental and analytical research carried out at the Penn State Propulsion Engineering Research Center in support of NASA's plan to develop advanced technologies for future single stage to orbit (SSTO) propulsion systems. The focus of the work is on understanding specific technical issues related to bi-propellant and tri-propellant thrusters. The experiments concentrate on both cold flow demonstrations and hot-fire uni-element tests to demonstrate concepts that can be incorporated into hardware design and development. The analysis is CFD-based and is intended to support the design and interpretation of the experiments and to extrapolate findings to full-scale designs. The research is divided into five main categories that impact various SSTO development scenarios. The first category focuses on RP-1/gaseous hydrogen (GH2)/gaseous oxygen (GO2) tri-propellant combustion with specific emphasis on understanding the benefits of hydrogen addition to RP-1/oxygen combustion and in developing innovative injector technology. The second category investigates liquid oxygen (LOX)/GH2 combustion at main chamber near stoichiometric conditions to improve understanding of existing LOX/GH2 rocket systems. The third and fourth categories investigate the technical issues related with oxidizer-rich and fuel-rich propulsive concepts, issues that are necessary for developing the full-flow engine cycle. Here, injector technology issues for both LOX/GH2 and LOX/RP-1 propellants are examined. The last category, also related to the full-flow engine cycle, examines injector technology needs for GO2/GH2 propellant combustion at near-stoichiometric conditions for main chamber application.

  10. Coccolithophores in the Gulf of Maine

    NASA Technical Reports Server (NTRS)

    2002-01-01

    Earlier this summer, trillions of calcite (limestone) coated phytoplankton, known as coccolithophores, appeared in the waters off the coast of Maine. This true color image of the coccolithophore bloom was acquired on July 11, 2002, by the Moderate-resolution Imaging Spectroradiometer (MODIS), flying aboard NASA's Terra spacecraft. The bloom is the large bluish-green patch in the center of the image in the Gulf of Maine. Unlike any other plant in the ocean, coccolithophores surround themselves with microscopic plating made of calcite. These scales, known as coccoliths, are shaped like hubcaps and are only three one-thousandths of a millimeter in diameter. What coccoliths lack in size, they make up in volume. At any one time a single coccolithophore is attached to or surrounded by at least 30 scales. Additional coccoliths are dumped into the water when the coccolithophores multiply asexually, die or simply make too many scales. In areas with trillions of coccolithophores, the waters will turn an opaque turquoise from the dense cloud of coccoliths. (Click to read more about coccolithophores.) Though there are always coccoliths in the Gulf of Maine, the area hasn't seen a bloom like this one since 1989. Currently, NASA researchers are studying the bloom aboard a ferry in the gulf in an attempt to measure the bloom's density and depth. So far the bloom appears to be about 20 to 25 meters thick and contains nearly half a million tons of calcite.

    This paper presents the configuration of a SCADA based telemetry system for the main Yugoslav gas pipeline network. A central supervising SCADA station is realized by using reliable industrial PC stations interconnected via a LAN. The key features of this SCADA are open architecture, hot stand-by, an effective MMI subsystem and an information link to the Enterprise Information System. In order to achieve better supervision and control over the gas-transport process, basic SCADA functions are supplemented with a decision support system based on trend analysis and a steady-state simulation model.

    2003-06-02

    In order to achieve an increase in proton intensity, Fermilab Main Injector will use a stacking process called ''slip stacking''. The intensity will be doubled by injecting one train of bunches at a slightly lower energy, another at a slightly higher energy, then bringing them together for the final capture. Beam studies have started for this process and we have already verified that, at least for a low beam intensity, the stacking procedure works as expected. For high intensity operation, development work of the feedback and feedforward systems is under way.

    2015-01-01

    Selective Laser Melting (SLM) was utilized to fabricate a liquid hydrogen valve housing typical of those found in rocket engines and main propulsion systems. The SLM process allowed for a valve geometry that would be difficult, if not impossible to fabricate by traditional means. Several valve bodies were built by different SLM suppliers and assembled with valve internals. The assemblies were then tested with liquid nitrogen and operated as desired. One unit was also burst tested and sectioned for materials analysis. The design, test results, and planned testing are presented herein.

  18. Inner main belt asteroids in Slivan states?

    NASA Astrophysics Data System (ADS)

    Vraštil, J.; Vokrouhlický, D.

    2015-07-01

    Context. The spin state of ten asteroids in the Koronis family has previously been determined. Surprisingly, all four asteroids with prograde rotation were shown to have spin axes nearly parallel in the inertial space. All asteroids with retrograde rotation had large obliquities and rotation periods that were either short or long. The Yarkovsky-O'Keefe-Radzievskii-Paddack (YORP) effect has been demonstrated to be able to explain all these peculiar facts. In particular, the effect causes the spin axes of the prograde rotators to be captured in a secular spin-orbit resonance known as Cassini state 2, a configuration dubbed "Slivan state". Aims: It has been proposed based on an analysis of a sample of asteroids in the Flora family that Slivan states might also exist in this region of the main belt. This is surprising because convergence of the proper frequency s and the planetary frequency s6 was assumed to prevent Slivan states in this zone. We therefore investigated the possibility of a long-term stable capture in the Slivan state in the inner part of the main belt and among the asteroids previously observed. Methods: We used the swift integrator to determine the orbital evolution of selected asteroids in the inner part of the main belt. We also implemented our own secular spin propagator into the swift code to efficiently analyze their spin evolution. Results: Our experiments show that the previously suggested Slivan states of the Flora-region asteroids are marginally stable for only a small range of the flattening parameter Δ. Either the observed spins are close to the Slivan state by chance, or additional dynamical effects that were so far not taken into account change their evolution. We find that only the asteroids with very low-inclination orbits (lower than ≃4°, for instance) could follow a similar evolution path as the Koronis members and be captured in their spin state into the Slivan state.

    Twenty of the peat deposits in Penobscot County, Maine contain an estimated 29,282,000 short tons air-dried peat. The peat is chiefly sphagnum moss and reed-sedge of high quality according to ASTM standards for agricultural and horticultural use. Analyses show that this same volume has high fuel value, low sulfur and high hydrogen contents compared with lignite and sub-bituminous coal, which may indicate that it also has potential for fuel use. On the basis of the metallic trace element content, one area within the region containing the 20 deposits has been delineated for further bedrock studies.

  1. Pendulum Motion in Main Parachute Clusters

    NASA Technical Reports Server (NTRS)

    Ray, Eric S.; Machin, Ricardo A.

    2015-01-01

    The coupled dynamics of a cluster of parachutes to a payload are notoriously difficult to predict. Often the payload is designed to be insensitive to the range of attitude and rates that might occur, but spacecraft generally do not have the mass and volume budgeted for this robust of a design. The National Aeronautics and Space Administration (NASA) Orion Capsule Parachute Assembly System (CPAS) implements a cluster of three mains for landing. During testing of the Engineering Development Unit (EDU) design, it was discovered that with a cluster of two mains (a fault tolerance required for human rating) the capsule coupled to the parachute cluster could get into a limit cycle pendulum motion which would exceed the spacecraft landing capability. This pendulum phenomenon could not be predicted with the existing models and simulations. A three phased effort has been undertaken to understand the consequence of the pendulum motion observed, and explore potential design changes that would mitigate this phenomenon. This paper will review the early analysis that was performed of the pendulum motion observed during EDU testing, summarize the analysis ongoing to understand the root cause of the pendulum phenomenon, and discuss the modeling and testing that is being pursued to identify design changes that would mitigate the risk.

  4. Ephemerides of the main Uranian satellites

    NASA Astrophysics Data System (ADS)

    Emelyanov, N. V.; Nikonchuk, D. V.

    2013-12-01

    A new model of motions of the five main Uranian satellites is developed. The model is based on all published observations made since the dates of the satellites' discoveries until 2008. The corresponding periods are 220 yr for Titania and Oberon, 160 yr for Ariel and Umbriel and 60 yr for Miranda. To fit the parameters of the satellites' motion, 30 139 observations were used, including those made by the Voyager 2 spacecraft as well as astrometric results of the photometric observations of mutual occultations and eclipses of the main Uranian satellites in 2007-2008. The model is elaborated by the numerical integration of equations of motions of the satellites where all necessary perturbating factors were taken into consideration. Basing on the model, new ephemerides of the main Uranian satellites were generated for the period from 1787 to 2031. The ephemerides are put to the MULTI-SAT ephemeris server. The root-mean-square residual of observed topocentric positions of the satellites and their ephemeris positions is 0.43 arcsec. Taking into account the weighting factors of the observations, this value is 0.12 arcsec. An attempt is also made to define from observations the parameters of the mechanical energy dissipation of the satellites' motion. The dissipation can be caused by both tides in the planet and by the tides in the satellites' bodies. Approximate values of the quadratic terms in the orbital longitudes are obtained. These values are equal to -(0.64 ± 0.11) × 10-11 d-2 for Ariel, -(0.08 ± 0.24) × 10-11 d-2 for Umbriel, -(0.29 ± 0.09) × 10-11 d-2 for Titania, -(0.32 ± 0.07) × 10-11 d-2 for Oberon and -(7.56 ± 1.15) × 10-11 d-2 for Miranda. The obtained parameters reveal deceleration in the orbital motion of the satellites, which results from the influence of the tides raised on the interior of Uranus that is rotating faster than the satellites.

    1972-01-01

    In the investigation of the failure of one of the three main parachutes of the Apollo 15 spacecraft, which collapsed at approximately 1825 meters after operating properly from deployment at 3050 meters, three conditions considered to be possible causes of the failure were produced. The suspect conditions were the proximity of the forward heat shield that passed the spacecraft at approximately 1825 meters, the dumping of the reaction control system hypergolic propellants at approximately 1825 meters, and the failing of a riser link found on a recovered parachute. (The failed parachute was not recovered). The remaining two parachutes functioned as planned and averted a catastrophic failure. The conclusions concerning the cause of the failure are discussed.

  6. Space transportation main engine cycle assessment process

    Mcconnaughey, H. V.; Lyles, G. M.

    1991-01-01

    The Advanced Launch System (ALS) program selection process for a space transportation main engine (STME) power cycle is described in terms of the methodology employed. Low cost, robustness, and high reliability are the primary parameters for engine choice, suggesting simplicity of design and efficient fabrication methods as the crucial characteristics. An evaluation methodology is developed based on the Pugh (1981) process and the King (1989) matrices. The cycle configurations considered are the gas generator (GG), the closed expander, and the open expander. The cycle assessment team determined that the GG cycle is favored by most cycle discriminators, based on an assessment of the characteristics in terms of ALS goals. The lower development risk of the GG-cycle STME is consistent with the goals of the ALS program in terms of reliability and cost efficiency.

  7. Intensity Limitations in Fermilab Main Injector

    SciTech Connect

    Chan, W.

    1997-06-01

    The design beam intensity of the FNAL Main Injector (MI) is 3 x 10{sup 13} ppp. This paper investigates possible limitations in the intensity upgrade. These include the space charge, transition crossing, microwave instability, coupled bunch instability, resistive wall, beam loading (static and transient), rf power, aperture (physical and dynamic), coalescing, particle losses and radiation shielding, etc. It seems that to increase the intensity by a factor of two from the design value is straightforward. Even a factor of five is possible provided that the following measures are to be taken: an rf power upgrade, a {gamma}{sub t}-jump system, longitudinal and transverse feedback systems, rf feedback and feedforward, stopband corrections and local shieldings.

    1985-10-01

    In March 1983, personnel at Philadelphia Electric's Eddystone No. 1 power plant discovered a through wall leak in the main steam outlet piping. This pipe was designed to carry steam at a pressure of 5300 psi (36,538 kPa) and a temperature of 1210F(654C). The pipe was made of 316 stainless steel and had been operated approximately 130,000 hours at the time that failure was discovered. Subsequent inspection revealed that many OD cracks existed in this piping system. This paper details the investigation into the cause of the failure. The following elements are highlighted: the in-place metallography which successfully used the plastic replica technique; the elasticplastic stress analysis and life prediction techniques carried out to assess probable failure modes and loadings; and the experimental stress analysis which was conducted to confirm analytical hypotheses.

    The European Extra Large Telescope is ESO's biggest astronomical telescope project. The E-ELT is an active and adaptive telescope. It has an astigmatic optical solution (five mirrors, including two flat ones). The telescope structure is of alt-azimuth type able to support a primary mirror with an equivalent diameter of 40 m. The telescope will be installed in a high-seismicity zone, in Cerro Armazones, Antofagasta Region, Chile, at an altitude of 3046 metres above sea level. This has significantly affected the boundary conditions and safety aspects considered during the project. The scope of the paper describes the Telescope Main Structure configuration developed by Empresarios Agrupados (Spain) during the FEED Studies performed from June 2009 to July 2011 in the frame of ESO Contracts. Most of the solutions implemented were extrapolated from existing installations in which Empresarios Agrupados has participated, adjusting for the extra large size of this new telescope.

    The review is made of the problems of ITER optical diagnostics. Most of these problems will be related to the intensive neutron radiation from hot plasma. At a high level of radiation loads the most types of materials gradually change their properties. This effect is most critical for optical diagnostics because of degradation of optical glasses and mirrors. The degradation of mirrors, that collect the light from plasma, basically will be induced by impurity deposition and (or) sputtering by charge exchange atoms. Main attention is paid to the search of glasses for vacuum windows and achromatic lens which are stable under ITER irradiation conditions. The last results of irradiation tests in nuclear reactor of candidate silica glasses KU-1, KS-4V and TF 200 are presented. An additional problem is discussed that deals with the stray light produced by multiple reflections from the first wall of the intense light emitted in the divertor plasma.

  11. The shuttle main engine: A first look

    1996-01-01

    Anyone entering the Space Shuttle Main Engine (SSME) team attends a two week course to become familiar with the design and workings of the engine. This course provides intensive coverage of the individual hardware items and their functions. Some individuals, particularly those involved with software maintenance and development, have felt overwhelmed by this volume of material and their lack of a logical framework in which to place it. To provide this logical framework, it was decided that a brief self-taught introduction to the overall operation of the SSME should be designed. To aid the people or new team members with an interest in the software, this new course should also explain the structure and functioning of the controller and its software. This paper presents a description of this presentation.

    The Heavy Hydrocarbon Main Injector Program was an analytical, design, and test program to demonstrate an injection concept applicable to an Isolated Combustion Compartment of a full-scale, high pressure, LOX/RP-1 engine. Several injector patterns were tested in a 3.4-in. combustor. Based on these results, features of the most promising injector design were incorporated into a 5.7-in. injector which was then hot-fire tested. In turn, a preliminary design of a 5-compartment 2D combustor was based on this pattern. Also the additional subscale injector testing and analysis was performed with an emphasis on improving analytical techniques and acoustic cavity design methodology. Several of the existing 3.5-in. diameter injectors were hot-fire tested with and without acoustic cavities for spontaneous and dynamic stability characteristics.

    The potential importance of iodine for marine boundary layer (MBL) chemistry has found increasing recognition in recent years. However, observations of the key iodine species are sparse and the chemical reactions of the iodine oxides are not well understood. Here we present Differential Optical Absorption Spectroscopy observations of IO, OIO in the MBL of the Gulf of Maine, U.S., during Summer 2004. We report the first daytime observation of OIO, indicating that this compound is rather photostable. Mixing ratios of IO were similar to, and those of OIO higher than, values reported for European coastal sites. Calculations with the one-dimensional model MISTRA show that the observed simultaneous presence of elevated OIO and NOx cannot be explained by currently known iodine chemistry. Our results lead to the conclusion that thus far unknown chemical reactions of iodine oxides, probably involving iodine nitrates, might occur in the MBL.

  14. STS-86 Landing (Main Gear Touchdown)

    1997-01-01

    The Space Shuttle orbiter Atlantis touches down on Runway 15 of the KSC Shuttle Landing Facility (SLF) to complete the nearly 11- day STS-86 mission. Main gear touchdown was at 5:55:09 p.m. EDT on Oct. 6, 1997. The unofficial mission-elapsed time at main gear touchdown was 10 days, 19 hours, 20 minutes and 50 seconds. The first two landing opportunities on Sunday were waved off because of weather concerns. The 87th Space Shuttle mission was the 40th landing of the Shuttle at KSC. On Sunday evening, the Space Shuttle program reached a milestone: The total flight time of the Shuttle passed the two-year mark. STS-86 was the seventh of nine planned dockings of the Space Shuttle with the Russian Space Station Mir. STS-86 Mission Specialist David A. Wolf replaced NASA astronaut and Mir 24 crew member C. Michael Foale, who has been on the Mir since mid-May. Foale returned to Earth on Atlantis with the remainder of the STS-86 crew. The other crew members are Commander James D. Wetherbee, Pilot Michael J. Bloomfield, and Mission Specialists Wendy B. Lawrence, Scott E. Parazynski, Vladimir Georgievich Titov of the Russian Space Agency, and Jean-Loup J.M. Chretien of the French Space Agency, CNES. Wolf is scheduled to remain on the Mir until the STS-89 Shuttle mission in January. Besides the docking and crew exchange, STS-86 included the transfer of more than three-and-a- half tons of science/logistical equipment and supplies between the two orbiting spacecraft. Parazynski and Titov also conducted a spacewalk while Atlantis and the Mir were docked.

  15. Remotely triggered earthquakes following moderate main shocks

    Hough, S.E.

    2007-01-01

    Since 1992, remotely triggered earthquakes have been identified following large (M > 7) earthquakes in California as well as in other regions. These events, which occur at much greater distances than classic aftershocks, occur predominantly in active geothermal or volcanic regions, leading to theories that the earthquakes are triggered when passing seismic waves cause disruptions in magmatic or other fluid systems. In this paper, I focus on observations of remotely triggered earthquakes following moderate main shocks in diverse tectonic settings. I summarize evidence that remotely triggered earthquakes occur commonly in mid-continent and collisional zones. This evidence is derived from analysis of both historic earthquake sequences and from instrumentally recorded M5-6 earthquakes in eastern Canada. The latter analysis suggests that, while remotely triggered earthquakes do not occur pervasively following moderate earthquakes in eastern North America, a low level of triggering often does occur at distances beyond conventional aftershock zones. The inferred triggered events occur at the distances at which SmS waves are known to significantly increase ground motions. A similar result was found for 28 recent M5.3-7.1 earthquakes in California. In California, seismicity is found to increase on average to a distance of at least 200 km following moderate main shocks. This supports the conclusion that, even at distances of ???100 km, dynamic stress changes control the occurrence of triggered events. There are two explanations that can account for the occurrence of remotely triggered earthquakes in intraplate settings: (1) they occur at local zones of weakness, or (2) they occur in zones of local stress concentration. ?? 2007 The Geological Society of America.

  16. Debiasing the Main-Belt Asteroid Population

    NASA Astrophysics Data System (ADS)

    Spahr, Timothy Bruce

    1998-12-01

    We present here two general techniques to remove observational selection effects from asteroid surveys. When applied to two specific asteroid surveys, these methods have allowed the first computation of the debiased distribution of asteroidal orbital elements and sizes for the first time. The first survey was conducted in 1960. Advances in computing have allowed the data to be re-analyzed using an existing computer program and given a much more rigorous statistical treatment. The survey was confined to the near-ecliptic at opposition, therefore its usefulness is limited with regard to highly inclined orbits. To compensate for this limitation, we conducted our own survey aimed specifically at high-inclination objects. Since these orbits are, in general, distributed differently than lower-inclination orbits, removing observational selection effects required creating a statistical technique using Monte-Carlo type simulations. The results of this work show no evidence for differing slopes of the size-frequency distribution throughout the asteroid belt, from the highly inclined Hungaria-type asteroids in the inner edge of the belt (1.8-2.0 AU), to the outer belt (3-3.5 AU). The slopes of the absolute-magnitude frequency distributions, being less than 0.5, show that the asteroidal size distribution is somewhat shallower than what would be predicted assuming the asteroids to be a collisionally evolved population of bodies with size-independent impact strengths. Also determined are rough numbers of asteroids in the main dynamical families of Eos, Maria, Themis, and Koronis, which comprise a significant fraction of the total number of objects in the main belt. This work has also resulted in the discovery of a new asteroid dynamical family, and possibly two new asteroid groups.

  19. Universities Scale Like Cities

    PubMed Central

    van Raan, Anthony F. J.

    2013-01-01

    Recent studies of urban scaling show that important socioeconomic city characteristics such as wealth and innovation capacity exhibit a nonlinear, particularly a power law scaling with population size. These nonlinear effects are common to all cities, with similar power law exponents. These findings mean that the larger the city, the more disproportionally they are places of wealth and innovation. Local properties of cities cause a deviation from the expected behavior as predicted by the power law scaling. In this paper we demonstrate that universities show a similar behavior as cities in the distribution of the ‘gross university income’ in terms of total number of citations over ‘size’ in terms of total number of publications. Moreover, the power law exponents for university scaling are comparable to those for urban scaling. We find that deviations from the expected behavior can indeed be explained by specific local properties of universities, particularly the field-specific composition of a university, and its quality in terms of field-normalized citation impact. By studying both the set of the 500 largest universities worldwide and a specific subset of these 500 universities -the top-100 European universities- we are also able to distinguish between properties of universities with as well as without selection of one specific local property, the quality of a university in terms of its average field-normalized citation impact. It also reveals an interesting observation concerning the working of a crucial property in networked systems, preferential attachment. PMID:23544062

    The philosophy of my life is to keep encouraging children to think beyond they could achieve easily. I understand children are adaptive to change and take things with an open mind. They are ready to experiment with new things and dare to dream big. I am fortunate to being a teacher by profession and thus I always attempt experimenting, observing, and participating with other children and adults. Children learn through play. From birth, children are active participants in building their own understanding. Teachers prepare the environment to help each child build on what they already know. It is such a great pleasure to observe every young kid that becomes excited and curious to know when we show them the Universe pictures and tell them about the strange objects in our Universe. So my aim is to keep them ignited by doing different activities throughout the year related to Space. I am always a firm believer of: Creativity is the key to success in the future, and primary education is where teachers can bring creativity in children at that level. One of my main ways of teaching is to conduct various presentations on The Solar System and beyond and debates on Space explorations. A Planet making project is one of the all-time favorite project for my students where they dare to dream to fly in the universe, and with their imagination, kids make different celestial objects and present them. To inculcate scientific attitude I arrange film screening, simulation exercises and quizzes on various topics of astronomy. Every year we celebrate World Space Week 4th to 10th of Oct. The motivation among all came through different hands-on activities like-painting, slogan competition, topics related to space, poetry and essay writing on various topics related to astronomy, assembly presentations in school. I am indeed overwhelmed when I started the very special Space and Astronomy club where young toddlers are involved in different activities like a star gazing program, conducting

    2012-07-01

    The 1917-25 planning and construction at the University of Michigan of a new University Hospital, later dubbed Old Main, offers a noteworthy case study of the formal convergence of hospital and factory in early twentieth-century America. Designed by Albert Kahn, the architect responsible for Ford Motor Company's archetypal automobile plants, and located in Ann Arbor, Michigan, less than forty miles from Detroit's burgeoning factory landscape, Old Main was well positioned to reflect the values of industry in both appearance and operation. The building's outer surface represents a striking departure from the historicism that characterized several other hospitals of this period, while plans for the building's novel diagnostic unit demonstrate unique operational parallels to the assembly line model of production. Ultimately, Old Main's industrial design similarities cast it as a precociously modernist hospital, relating streamlined form to function more explicitly than many of its contemporary institutions.

    2016-02-01

    We present a universal knot polynomials for 2- and 3-strand torus knots in adjoint representation, by universalization of appropriate Rosso-Jones formula. According to universality, these polynomials coincide with adjoined colored HOMFLY and Kauffman polynomials at SL and SO/Sp lines on Vogel's plane, respectively and give their exceptional group's counterparts on exceptional line. We demonstrate that [m,n]=[n,m] topological invariance, when applicable, take place on the entire Vogel's plane. We also suggest the universal form of invariant of figure eight knot in adjoint representation, and suggest existence of such universalization for any knot in adjoint and its descendant representations. Properties of universal polynomials and applications of these results are discussed.

    The 5th INTEGRAL workshop "The INTEGRAL Universe" was held at the premises of the Bayerische Akademie der Wissenschaften in Munich, Germany, from February 16 - 20, 2004. The workshop was attended by over 230 scientists from all over the world. The aim of the workshop was twofold: to bring the scientists together who are using data from the INTEGRAL mission and to present first results which were obtained by the four INTEGRAL instruments during the first 18 months of operation. It was for the first time after launch that INTEGRAL results were presented and discussed in a broader scientific context and compared with results obtained with other instruments at different wavelengths (especially in the optical, infrared and radio). Naturally the results concentrated mainly on the hard X-ray regime since photons are plentiful and the sensitivity of the INTEGRAL instruments is best there. But also very interesting early results at low-energy gamma-rays, especially on gamma-ray lines, were presented. Because of INTEGRAL?s ability to measure and localize gamma-ray bursts quickly, this topic also drew a lot of attention and stimulating results were presented. The following list emphasizes the scientific importance of the topics which were covered by 6 invited, 1 special and 64 contributed talks as well as about 180 posters: + Nucleosynthesis and gamma-ray line spectroscopy + Pulsars + X-ray binaries (with neutron stars and black holes) + Interstellar continuum emission + AGN (Seyferts and Blazars) + Clusters of galaxies + Cosmic background radiation + Gamma-ray bursts + Unidentified gamma-ray sources + Solar flare gamma-rays + Data analysis (posters only) * Future instruments and missions (posters only)

Here we attempt to identify mass loss in main belt asteroids (MBAs) from these data. A primary motivation is to understand the role that asteroids may play in supplying dust and gas for debris disks. This work focuses on finding methods to automatically pick out asteroids that have qualities indicating possible mass loss. Two methods were chosen: looking for flux above a certain threshold in the asteroid's radial profile, and comparing its PSF to that of a point source. After sifting through 490 asteroids, several have passed these tests and should be followed up with a more rigorous analysis.Sandberg was supported by the NOAO/KPNO Research Experience for Undergraduates (REU) Program which is funded by the National Science Foundation Research Experiences for Undergraduates Program (AST-1262829)

    Severe flooding occurred in northern Maine from April 28 to May 1, 2008, and damage was extensive in the town of Fort Kent (Lombard, 2010). Aroostook County was declared a Federal disaster area on May 9, 2008. The extent of flooding on both the Fish and St. John Rivers during this event showed that the current Federal Emergency Management Agency (FEMA) Flood Insurance Study (FIS) and Flood Insurance Rate Map (FIRM) (Federal Emergency Management Agency, 1979) were out of date. The U.S. Geological Survey (USGS) conducted a study to develop a flood inundation map library showing the areas and depths for a range of flood stages from bankfull to the flood of record for Fort Kent to complement an updated FIS (Federal Emergency Management Agency, in press). Hydrologic analyses that support the maps include computer models with and without the levee and with various depths of backwater on the Fish River. This fact sheet describes the methods used to develop the maps and describes how the maps can be accessed.

  12. The main magnetic field of Jupiter

    Acuna, M. H.; Ness, N. F.

    1976-01-01

    The main magnetic field of Jupiter has been measured by the Goddard Space Flight Center flux gate magnetometer on Pioneer 11. Analysis of the data yields a more detailed model than that obtained from Pioneer 10 results. In a spherical harmonic octupole representation the dipole term (with opposite polarity to earth's) has a magnitude of 4.28 G times the radial distance cubed at a tilt angle of 9.6 deg and a system 111 longitude of 232 deg. The quadrupole and octupole moments are 24% and 21% of the dipole, respectively. This leads to a significant deviation of the planetary magnetic field from a simple offset dipole topology at distances of less than three times the radial distance. The north polar field strength is 14 G, and in the Northern Hemisphere the 'footprint' of the Io associated flux tube traverses the magnetic polar region. Associated L shell splitting in the radiation belts, warping of the charged particle equatorial planes, and enhanced absorption effects due to the satellites Amalthea and Io are expected as a result of the field complexity.

    2015-07-01

    We determine the slip rate and pattern of interseismic coupling on the Main Himalayan Thrust along the entire Himalayan arc based on a compilation of geodetic, interferometric synthetic aperture radar, and microseismicity data. We show that convergence is perpendicular to the arc and increases eastwards from 13.3 ± 1.7 mm/yr to 21.2 ± 2.0 mm/yr. These rates are comparable to geological and geomorphic estimates, indicating an essentially elastic geodetic surface strain. The interseismic uplift rate predicted from the coupling model closely mimics the topography, suggesting that a small percentage of the interseismic strain is permanent. We find that the fault is fully locked along its complete length over about 100 km width. We don't find any resolvable aseismic barrier that could affect the seismic segmentation of the arc and limit the along-strike propagation of seismic ruptures. The moment deficit builds up at a rate of 15.1 ± 1 × 1019 N m/yr for the entire length of the Himalaya.

    Lead-acid batteries used in cars accounted for 65% of the lead in MSW in 1986, and rechargeable nickel-cadmium batteries contributed 52% of the cadmium discarded in the U.S. since 1980. According to an EPA draft report, other major sources of lead are consumer electronics 27%; glass and ceramics, 4%; and such plastic items as PVC resins. Other less significant sources of lead are soldered cans, pigments, brass and bronze products, light bulbs, rubber products, used oil, and lead foil wine bottle wrappers. Cadmium comes from other sources in addition to nickel-cadmium batteries. Plastics using cadmium as stabilizer (mainly PVC) or in pigments contribute 28% of the total amount entering the waste stream. Consumer electronics account for 9% (including cadmium-plated steel chassis on old TV sets and radios); appliances which used to be built with cadmium-plated parts to resist corrosion, 5% pigments, particularly those used in non-newspaper printing inks, textile dyes and paints, 4%; and glass and ceramics, 1.6% of the total.

    Specific and nonspecific DNA complex formation with human uracil-DNA glycosylase, 8-oxoguanine-DNA glycosylase, and apurine/apyrimidine endonuclease, as well as with E. coli 8-oxoguanine-DNA glycosylase and RecA protein was analyzed using the method of stepwise increase in DNA-ligand complexity. It is shown that high affinity of these enzymes to any DNA (10(-4)-10(-8) M) is provided by a large number of weak additive contacts mainly with DNA internucleoside phosphate groups and in a less degree with bases of nucleotide links "covered" by protein globules. Enzyme interactions with specific DNA links are comparable in efficiency with weak unspecific contacts and provide only for one-two orders of affinity (10(-1)-10(-2) M), but these contacts are extremely important at stages of DNA and enzyme structural adaptation and catalysis proper. Only in the case of specific DNA individual for each enzyme alterations in DNA structure provide for efficient adjustment of reacting enzyme atoms and DNA orbitals with accuracy up to 10-15° and, as a result, for high reaction rate. Upon transition from nonspecific to specific DNA, reaction rate (k(cat)) increases by 4-8 orders of magnitude. Thus, stages of DNA and enzyme structural adaptation as well as catalysis proper are the basis of specificity of repair enzymes. PMID:21568843

    Using the Spectral Analysis Method introduced by Michtchenko et al. (2002), we construct a dynamic portrait of the main asteroid belt. For this task, we use information extracted from the distribution of test particles (which were initially placed on a perfectly rectangular grid of initial conditions) after 4.2 Myr of gravitational interactions with the Sun and five planets, from Mars to Neptune. We illustrate in detail the asteroidal behavior on the dynamical, averaged and frequency maps. On the maps, we superpose information on the proper elements and proper frequencies of real objects, extracted from the data base, Ast- DyS (http://hamilton.dm.unipi.it/astdys), constructed by Milani and Knežević (2003). A comparison of the maps with the distribution of real objects allows us to detect dynamical mechanisms acting in the domain under study. These mechanisms are related to meanmotion and secular resonances. We note that the twoand three-body mean-motion resonances and the secular resonances (strong linear and weaker non-linear) play an important role in the diffusive transportation of the objects and the formation of the clumps which could be misidentified as asteroid families. The longlasting action of the resonances, overlaid with the Yarkovsky effect, may explain many observed features of the density, size and taxonomic distributions of the asteroids.

    2013-10-01

    Beginning in May 2013, the KArlsruhe TRItium Neutrino experiment (KATRIN) collaboration began measurements to commission the 10-m diameter main spectrometer. KATRIN utilizes the spectrometer to provide magnetic adiabatic collimation and electrostatic filtering designed to analyze the tritium beta decay spectrum for contributions from the neutrino mass. In order to achieve an order-of-magnitude improvement on previous neutrino mass experiments the desired sensitivity of the apparatus must be 200 meV in the decay endpoint region. Goals of the recent measurements include identification and reduction of backgrounds and determination of the spectrometer transfer function. Backgrounds have been probed by utilizing electromagnetic field configurations to explore decays in the spectrometer, Penning traps and field emission. A 148-pixel PIN diode array is employed to detect particles exiting the spectrometer, which permits angular and radial distributions of particles to be analyzed. This has allowed for high precision comparison between measurements and simulations of expected backgrounds to be investigated in order to commission the spectrometer. This work is supported by grants from the DOE Office of Nuclear Physics and the Helmholtz Association.

    The operating requirements established by NASA for the SSME were considerably more demanding than those for earlier rocket engines used in the military launch vehicles or Apollo program. The SSME, in order to achieve the high performance, low weight, long life, reusable objectives, embodied technical demands far in excess of its predecessor rocket engines. The requirements dictated the use of high combustion pressure and the staged combustion cycle which maximizes performance through total use of all propellants in the main combustion process. This approach presented a myriad of technical challenges for maximization of performance within attainable state of the art capabilities for operating pressures, operating temperatures and rotating machinery efficiencies. Controlling uniformity of the high pressure turbomachinery turbine temperature environment was a key challenge for thrust level and life capability demanding innovative engineering. New approaches in the design of the components were necessary to accommodate the multiple use, minimum maintenance objectives. Included were the use of line replaceable units to facilitate field maintenance automatic checkout and internal inspection capabilities.

    2009-01-01

    During August and September 2005, dissolved oxygen, temperature, pH, specific conductance, streamflow, and light intensity (LI) were determined continuously at six sites defining five reaches on Meduxnekeag River above and below Houlton, Maine. These data were collected as input for a dual-station whole-stream metabolism model to evaluate primary productivity in the river above and below Houlton. The river receives nutrients and organic matter from tributaries and the Houlton wastewater treatment plant (WWTP). Model output estimated gross and net primary productivity for each reach. Gross primary productivity (GPP) varied in each reach but was similar and positive among the reaches. GPP was correlated to LI in the four reaches above the WWTP but not in the reach below. Net primary productivity (NPP) decreased in each successive downstream reach and was negative in the lowest two reaches. NPP was weakly related to LI in the upper two reaches and either not correlated or negatively correlated in the lower three reaches. Relations among GPP, NPP, and LI indicate that the system is heterotrophic in the downstream reaches. The almost linear decrease in NPP (the increase in metabolism and respiration) indicates a cumulative effect of inputs of nutrients and organic matter from tributaries that drain agricultural land, the town of Houlton, and the discharges from the WWTP.

    To assess mercury contamination of fish in Maine, fish were collected from 120 randomly selected lakes. The collection goal for each lake was five fish of the single most common sport fish species within the size range commonly harvested by anglers. Skinless, boneless fillets of fish from each lake were composited, homogenized, and analyzed for total mercury. The two most abundant species, brook trout Salvelinus fontinalis and smallmouth bass Micropterus dolomieu, were also analyzed individually. The composite fish analyses indicate high concentrations of mercury, particularly in large and long-lived nonsalmonid species. Chain pickerel Esox niger, smallmouth bass, largemouth bass Micropterus salmoides, and white perch Morone americana had the highest average mercury concentrations, and brook trout and yellow perch Perca flavescens had the lowest. The mean species composite mercury concentration was positively correlated with a factor incorporating the average size and age of the fish. Lakes containing fish with high mercury concentrations were not clustered near known industrial or population centers but were commonest in the area within 150 km of the seacoast, reflecting the geographical distribution of species that contained higher mercury concentrations. Stocked and wild brook trout were not different in length or weight, but wild fish were older and had higher mercury concentrations. Fish populations maintained by frequent introductions of hatchery-produced fish and subject to high angler exploitation rates may consist of younger fish with lower exposure to environmental mercury and thus contain lower concentrations than wild populations.

    Automatika, Inc. was contracted by the Department of Energy (DOE) and with co-funding from the New York Gas Group (NYGAS), to develop an in-pipe natural gas prototype measurement and wireless communications system for assessing and monitoring distribution networks. A prototype system was built for low-pressure cast-iron mains and tested in a spider- and serial-network configuration in a live network in Long Island with the support of Keyspan Energy, Inc. The prototype unit combined sensors capable of monitoring pressure, flow, humidity, temperature and vibration, which were sampled and combined in data-packages in an in-pipe master-slave architecture to collect data from a distributed spider-arrangement, and in a master-repeater-slave configuration in serial or ladder-network arrangements. It was found that the system was capable of performing all data-sampling and collection as expected, yielding interesting results as to flow-dynamics and vibration-detection. Wireless in-pipe communications were shown to be feasible and valuable data was collected in order to determine how to improve on range and data-quality in the future.

    A universal entangler is a very powerful fault-tolerant entangling device for generating quantum entanglements from any joint states. Our paper aims to address the construction of universal entanglers. We prove that universal entanglers may be obtained from random unitary gates according to the Harr measure. The success probability is close to 1 for large system spaces. This result represents the typical density of entanglement subspaces in large state spaces. It also partially solves an open problem of universal bipartite entanglers and is explained by some experiment simulations.

    The distribution of 222Rn has been measured in the sixteen counties of Maine, U.S.A. by liquid scintillation counting of water samples from more than two thousand public and private wells. Three hundred and fifty of these wells have been characterized for geology and hydrology. Airborne radon has been measured in seventy houses with grab samples and in eighteen houses for 5-7 days each with continuously recording diffusion-electrostatic radon detectors. Concentrations of radon in water ranged from 20 to 180,000 pCi/l. Granite areas yielded the highest average levels (mean = 22,100 pCi/l.; n = 136), with considerable intra-granite variation. Metasedimentary rocks yielded levels characteristic of the lithology for metamorphic grades ranging from chlorite to andalusite. Sillimanite and higher-grade rocks yielded higher 222Rn levels, probably due to the intrusion of uranium-bearing pegmatites in these terranes. Airborne 222Rn in homes ranged from 0.05 to 210 pCi/l. At the high end of this range, doses will exceed recommended industrial limits. In some homes only a small fraction of the airborne 222Rn was due to the water supply. Average 222Rn levels in domestic water supplies for each of the 16 counties, calculated by areally averaging rock types and their associated 222Rn levels, were found to be significantly correlated with rates for all cancers combined and rates for lung and reproductive cancers in the counties. Although numerous factors other than cancer induction by indoor daughter exposures may be responsible for the observed correlations, these have not been investigated in detail. PMID:6885433

    Semiconvection is a form of mixing in thermally unstable regions that are partially stabilized by composition gradients. It has the greatest potential impact on the evolution of the cores of main sequence stars in the mass range 1.2 {M}⊙ -1.7 {M}⊙ . We present the first stellar evolution calculations using the new prescription for semiconvective mixing proposed by Wood et al. Semiconvection in stars is predominately layered semiconvection. In our model, the layer height is an adjustable parameter analogous to the mixing length in convection. The rate of mixing inside semiconvective regions is sensitively dependent on the layer height. We find a critical layer height that separates weak semiconvective mixing (where stellar evolution is well-approximated by ignoring semiconvection entirely and using the Ledoux criterion for convection) from strong semiconvective mixing (where all composition gradients are rapidly mixed, so stellar evolution is well-approximated by ignoring them altogether and using the Schwarzschild criterion for convection instead). This critical layer height is much smaller than the minimum layer height derived from simulations so we predict that stellar evolution is nearly the same as in models ran with the Schwarzschild criterion. We also investigate the effects of composition gradient smoothing, finding that it causes convective cores to artificially shrink in the absence of additional mixing beyond the convective boundary. Layered semiconvection with realistic layer heights provides enough such mixing to avoid this problem. Finally, we discuss the potential of detecting layered semiconvection and its implication on convective core sizes in solar-like oscillators.

    Since their identification as a new class of bodies by Hsieh and Jewitt in 2006 active asteroids (or Main Belt Comets, MBCs) have attracted a great deal of interest. Given that sublimation of volatile material (presumably water-ice) drives MBC activity, these bodies are probable candidates for delivering a significant amount of Earth's water. Dynamical studies suggest in-situ formation of MBCs as the remnants of the break-up of large icy asteroids. Also, collisions between MBCs and small objects might have exposed sub-surface water-ice triggering the cometary activity of these bodies. In order to advance the effort of understanding the nature of MBC activation, we have investigated these collision processes by simulating the impacts in detail using a smooth particle hydrodynamics (SPH) approach that includes material strength and fracture models. Our simulations cover a range of impact velocities (between 0.5 km/s and 5.3 km/s) and angles, allowing m-sized impactors to erode enough of an MBC's surface to expose volatiles and trigger its activation. We also varied the material strength of the active asteroid's surface to study its influence on crater depths and shapes. As expected, depending on the impact energy, impact angle, and MBC's material strength we observe different crater depths. Across all scenarios however, our results show that the crater depths do not exceed a few meters. This implies that if the activity of MBCs is due to sublimating water-ice, ice has to exist in no deeper than a few meters from the surface.

    Automatika, Inc. was contracted by the Department of Energy (DOE) and with co-funding from the Northeast Gas Association (NGA), to develop an in-pipe natural gas prototype measurement and wireless communications system for assessing and monitoring distribution networks. This projected was completed in April 2006, and culminated in the installation of more than 2 dozen GasNet nodes in both low- and high-pressure cast-iron and steel mains owned by multiple utilities in the northeastern US. Utilities are currently logging data (off-line) and monitoring data in real time from single and multiple networked sensors over cellular networks and collecting data using wireless bluetooth PDA systems. The system was designed to be modular, using in-pipe sensor-wands capable of measuring, flow, pressure, temperature, water-content and vibration. Internal antennae allowed for the use of the pipe-internals as a waveguide for setting up a sensor network to collect data from multiple nodes simultaneously. Sensor nodes were designed to be installed with low- and no-blow techniques and tools. Using a multi-drop bus technique with a custom protocol, all electronics were designed to be buriable and allow for on-board data-collection (SD-card), wireless relaying and cellular network forwarding. Installation options afforded by the design included direct-burial and external polemounted variants. Power was provided by one or more batteries, direct AC-power (Class I Div.2) and solar-array. The utilities are currently in a data-collection phase and intend to use the collected (and processed) data to make capital improvement decisions, compare it to Stoner model predictions and evaluate the use of such a system for future expansion, technology-improvement and commercialization starting later in 2006.

    Reconstructions of glacioisostatic rebound based on relative sea level in Maine and adjacent Canada do not agree well with existing geophysical models. In order to understand these discrepancies better, we investigated the lake-level history of 40-km-long Moosehead Lake in northwestern Maine. Glacioisostasy has affected the level of Moosehead Lake since deglaciation ca. 12,500 14C yr B.P. Lowstand features at the southeastern end and an abandoned outlet at the northwestern end of the lake indicate that the lake basin was tilted down to the northwest, toward the retreating ice sheet, by 0.7 m/km at 10,000 14C yr B.P. Water level then rose rapidly in the southeastern end of the lake, and the northwestern outlet was abandoned, indicating rapid relaxation of landscape tilt. Lowstand features at the northwestern end of the lake suggest that the lake basin was tilted to the southeast at ca. 8750 14C yr B.P., possibly as the result of a migrating isostatic forebulge. After 8000 14C yr B.P., water level at the southeastern end was again below present lake level and rose gradually thereafter. We found no evidence suggesting that postglacial climate change significantly affected lake level. The rebound history inferred from lake-level data is consistent with previous interpretations of nearby relative sealevel data, which indicate a significantly steeper and faster-moving ice-proximal depression and ice-distal forebulge than geophysical models predict. ?? 1998 University of Washington.

    We present initial results from observations and numerical analyses aimed at characterizing the main-belt comet P/2012 T1 (PANSTARRS). Optical monitoring observations were made between 2012 October and 2013 February using the University of Hawaii 2.2 m telescope, the Keck I telescope, the Baade and Clay Magellan telescopes, Faulkes Telescope South, the Perkins Telescope at Lowell Observatory, and the Southern Astrophysical Research Telescope. The object's intrinsic brightness approximately doubles from the time of its discovery in early October until mid-November and then decreases by {approx}60% between late December and early February, similar to photometric behavior exhibited by several other main-belt comets and unlike that exhibited by disrupted asteroid (596) Scheila. We also used Keck to conduct spectroscopic searches for CN emission as well as absorption at 0.7 {mu}m that could indicate the presence of hydrated minerals, finding an upper limit CN production rate of Q{sub CN} < 1.5 Multiplication-Sign 10{sup 23} mol s{sup -1}, from which we infer a water production rate of Q{sub H{sub 2O}}<5 Multiplication-Sign 10{sup 25} mol s{sup -1}, and no evidence of the presence of hydrated minerals. Numerical simulations indicate that P/2012 T1 is largely dynamically stable for >100 Myr and is unlikely to be a recently implanted interloper from the outer solar system, while a search for potential asteroid family associations reveals that it is dynamically linked to the {approx}155 Myr old Lixiaohua asteroid family.

    The US Department of Energy (DOE) proposes to build a beamline on the Fermi National Accelerator Laboratory (Fermilab) site to accommodate an experimental research program in neutrino physics. The proposed action, called Neutrino Beams at the Main Injector (NuMI), is to design, construct, operate and decommission a facility for producing and studying a high flux beam of neutrinos in the energy range of 1 to 40 GeV (1 GeV is one billion or 10{sup 9} electron volts). The proposed facility would initially be dedicated to two experiments, COSMOS (Cosmologically Significant Mass Oscillations) and MINOS (Main Injector Neutrino Oscillation Search). The neutrino beam would pass underground from Fermilab to northern Minnesota. A tunnel would not be built in this intervening region because the neutrinos easily pass through the earth, not interacting, similar to the way that light passes through a pane of glass. The beam is pointed towards the MINOS detector in the Soudan Underground Laboratory in Minnesota. Thus, the proposed project also includes construction, operation and decommissioning of the facility located in the Soudan Underground Laboratory in Minnesota that houses this MINOS detector. This environmental assessment (EA) has been prepared by the US Department of Energy (DOE) in accordance with the DOE`s National Environmental Policy Act (NEPA) Implementing Procedures (10 CFR 1021). This EA documents DOE`s evaluation of potential environmental impacts associated with the proposed construction and operation of NuMI at Fermilab and its far detector facility located in the Soudan Underground Laboratory in Minnesota. Any future use of the facilities on the Fermilab site would require the administrative approval of the Director of Fermilab and would undergo a separate NEPA review. Fermilab is a Federal high-energy physics research laboratory in Batavia, Illinois operated on behalf of the DOE by Universities Research Association, Inc.

    Severe main combustion chamber wall and main injector baffle element deterioration occurred during tests of Space Shuttle Main Engine 0209. One of the possible causes considered is ice formation and blockage of coolant to these components, resulting from the mixing of leaking hot turbine exhaust gas (hydrogen rich steam) and hydrogen coolant in the injector coolant cavity. The plausibility of ice blockage is investigated through simple mixing calculations for hot gas and hydrogen, investigation of condensation and water droplet formation, calculation of the freezing times for droplets, and the prediction of ice layer thicknesses. It is concluded that condensation and droplet formation can occur, and small water droplets that form can freeze very quickly when in contact with the cold coolant cavity surfaces. Copnservative analysis predicts, however, that the maximum thickness of the ice layers formed is too small to result in significant blockage of the coolant flow.

    Human-associated microbial communities have a crucial role in determining our health and well-being, and this has led to the continuing development of microbiome-based therapies such as faecal microbiota transplantation. These microbial communities are very complex, dynamic and highly personalized ecosystems, exhibiting a high degree of inter-individual variability in both species assemblages and abundance profiles. It is not known whether the underlying ecological dynamics of these communities, which can be parameterized by growth rates, and intra- and inter-species interactions in population dynamics models, are largely host-independent (that is, universal) or host-specific. If the inter-individual variability reflects host-specific dynamics due to differences in host lifestyle, physiology or genetics, then generic microbiome manipulations may have unintended consequences, rendering them ineffective or even detrimental. Alternatively, microbial ecosystems of different subjects may exhibit universal dynamics, with the inter-individual variability mainly originating from differences in the sets of colonizing species. Here we develop a new computational method to characterize human microbial dynamics. By applying this method to cross-sectional data from two large-scale metagenomic studies--the Human Microbiome Project and the Student Microbiome Project--we show that gut and mouth microbiomes display pronounced universal dynamics, whereas communities associated with certain skin sites are probably shaped by differences in the host environment. Notably, the universality of gut microbial dynamics is not observed in subjects with recurrent Clostridium difficile infection but is observed in the same set of subjects after faecal microbiota transplantation. These results fundamentally improve our understanding of the processes that shape human microbial ecosystems, and pave the way to designing general microbiome-based therapies. PMID:27279224

    For a number of years, NASA has relied primarily upon periodically updated versions of Rocketdyne's power balance model (PBM) to provide space shuttle main engine (SSME) steady-state performance prediction. A recent computational study indicated that PBM predictions do not satisfy fundamental energy conservation principles. More recently, SSME test results provided by the Technology Test Bed (TTB) program have indicated significant discrepancies between PBM flow and temperature predictions and TTB observations. Results of these investigations have diminished confidence in the predictions provided by PBM, and motivated the development of new computational tools for supporting SSME performance analysis. A multivariate least squares regression algorithm was developed and implemented during this effort in order to efficiently characterize TTB data. This procedure, called the 'gains model,' was used to approximate the variation of SSME performance parameters such as flow rate, pressure, temperature, speed, and assorted hardware characteristics in terms of six assumed independent influences. These six influences were engine power level, mixture ratio, fuel inlet pressure and temperature, and oxidizer inlet pressure and temperature. A BFGS optimization algorithm provided the base procedure for determining regression coefficients for both linear and full quadratic approximations of parameter variation. Statistical information relative to data deviation from regression derived relations was also computed.

    France, under the leadership of the French Space Agency (CNES), has set up a cooperative program with Austria, Belgium, Spain, Sweden, in order to develop a space Earth Observation system called PLEIADES. PLEIADES is a dual system, this means that it is intended to fulfill an extended panel of both civilian and Defense user's needs.. This paper reports the status of the satellite after its launch and the in orbit commissioning, the PLEIADES satellite first model has been launched at the end of year 2011, the second model will be launched about 12 months later. It describes the main mission characteristics and performances status. It exposes how the system, satellite and ground segment have been designed in order to be compliant with a dual exploitation between civilian and defense partners. The system is based on the use of a set of newly European developed technologies to feature the satellite. In order to maximize the agility of the satellite, weight and inertia have been reduced using a compact hexagonal shape for the satellite bus. The optical mission consists in Earth optical observation composed of 0.7 m nadir resolution for the panchromatic band and 2.8 m nadir resolution for the four multi-spectral bands. The image swath is about 20 km. PLEIADES delivers optical high resolution products consisting in a Panchromatic image, into which is merged a four multispectral bands image, orthorectified on a Digital Terrain Model (DTM). Thanks to the huge satellite agility obtained with control momentum gyros as actuators, the optical system delivers as well instantaneous stereo images, under different stereoscopic conditions and mosaic images, issued from along the track thus enlarging the field of view. The ground segment is composed of a dual ground center located in CNES Toulouse premises in charge of preparing the dual mission command plan and of the real time contacts with the satellite through a control center.

    The Bear Brook Watershed Manipulation project in Maine is a paired calibrated watershed study funded by the U.S. EPA. The research program is evaluating whole ecosystem response to elevated inputs of acidifying chemicals. The consists of a 2.5 year calibration period (1987-1989), nine years of chemical additions of (NH4)2SO4 (15N- and 34S-enriched for several years) to West Bear watershed (1989-1998), followed by a recovery period. The other watershed, East Bear, serves as a reference. Dosing is in six equal treatments/yr of 1800 eq SO4 and NH4/ha/yr, a 200% increase over 1988 loading (wet plus dry) for SO4 300% for N (wet NO3 + NH4). The experimental and reference watersheds are forested with mixed hard- and softwoods, and have thin acidic soils, areas of 10.2 and 10.7 ha and relief of 210 m. Thin till of variable composition is underlain by metasedimentary pelitic rocks and calc-silicate gneiss intruded by granite dikes and sills. For the period 1987-1995, precipitation averaged 1.4 m/yr, had a mean pH of 4.5, with SO4, NO3, and NH4 concentrations of 26, 14, and 7 ??eq/L, respectively. The nearly perrenial streams draining each watershed have discharges ranging from 0 (East Bear stops flowing for one to two months per year) to 150 L/sec. Prior to manipulation, East Bear and West Bear had a volume weighted annual mean pH of approximately 5.4, alkalinity = 0 to 4 ??eq/L, total base cations = 184 ??eq/L (sea-salt corrected = 118 ??eq/L), and SO4 = 100 to 111 ??eq/L. Nitrate ranged from 0 to 30 ??eq/L with an annual mean of 6 to 25 ??eq/L; dissolved organic carbon (DOC) ranged from 1 to 7 mg/L but was typically less than 3. Episodic acidification occurred at high discharge and was caused by dilution of cations, slightly increased DOC, significantly higher NO3, and the sea-salt effect.

  13. Rise of the main meniscus in rectangular capillaries: Experiments and modeling.

    PubMed

    Wu, Pingkeng; Zhang, Hua; Nikolov, Alex; Wasan, Darsh

    2016-01-01

    The rise of the main meniscus in rectangular capillaries is important in interpreting the phenomenon of fluid flow in porous media. Despite many experimental studies reported in the literature, there is no universal model for the rise of the main meniscus in either rectangular or square capillaries. In this work, we present an extensive experimental study and modeling of the rise of the main meniscus in both square and rectangular capillaries. Experimental work was carried out using three different liquids (water, ethanol, and hexadecane) in borosilicate glass and plastic (polystyrene) capillaries to investigate the effect of the contact angle and capillary size on the equilibrium main meniscus height. A universal model (an extended two-wall model) based on the Laplace equation was developed to predict the equilibrium height of the main meniscus in rectangular capillaries. Results have shown that, in a wide range of capillary sizes and contact angles, the predicted equilibrium heights of the main meniscus are in good agreement with the experimentally measured values.

  14. The Monte Carlo code MCSHAPE: Main features and recent developments

    NASA Astrophysics Data System (ADS)

    Scot, Viviana; Fernandez, Jorge E.

    2015-06-01

    MCSHAPE is a general purpose Monte Carlo code developed at the University of Bologna to simulate the diffusion of X- and gamma-ray photons with the special feature of describing the full evolution of the photon polarization state along the interactions with the target. The prevailing photon-matter interactions in the energy range 1-1000 keV, Compton and Rayleigh scattering and photoelectric effect, are considered. All the parameters that characterize the photon transport can be suitably defined: (i) the source intensity, (ii) its full polarization state as a function of energy, (iii) the number of collisions, and (iv) the energy interval and resolution of the simulation. It is possible to visualize the results for selected groups of interactions. MCSHAPE simulates the propagation in heterogeneous media of polarized photons (from synchrotron sources) or of partially polarized sources (from X-ray tubes). In this paper, the main features of MCSHAPE are illustrated with some examples and a comparison with experimental data.

    Wright, Bruce E.; Stewart, David B.

    1990-01-01

    The Bedrock Geologic Map of Maine was digitized and combined with digital geologic data for Quebec and the Gulf of Maine for the Quebec-Maine-Gulf of Maine Geologic Transect Project. This map is being combined with digital geophysical data to produce three-dimensional depictions of the subsurface geology and to produce cross sections of the Earth's crust. It is an essential component of a transect that stretches from the craton near Quebec City, Quebec, to the Atlantic Ocean Basin south of Georges Bank. The transect is part of the Global Geosciences Transect Project of the International Lithosphere Program. The Digital Line Graph format is used for storage of the digitized data. A coding scheme similar to that used for base category planimetric data was developed to assign numeric codes to the digitized geologic data. These codes were used to assign attributes to polygon and line features to describe rock type, age, name, tectonic setting of original deposition, mineralogy, and composition of igneous plutonic rocks, as well as faults and other linear features. The digital geologic data can be readily edited, rescaled, and reprojected. The attribute codes allow generalization and selective retrieval of the geologic features. The codes allow assignment of map colors based on age, lithology, or other attribute. The Digital Line Graph format is a general transfer format that is supported by many software vendors and is easily transferred between systems.

  15. The Transient Universe

    NASA Astrophysics Data System (ADS)

    Shappee, Benjamin John

    When one looks at the night sky, one usually gets the impression of a static and constant universe. Quite apart from appearances, the sky is teeming with violent, variable, and transient events that shape our universe. These capricious objects are not only penetrating probes into physical conditions too extreme for earthbound laboratories, but they are also useful tools to measure the universe. In this dissertation, I investigate the observational and theoretical properties of three classes of transient/variable objects: thermonuclear supernovae, Cepheid variable stars, and active galactic nuclei.

    Hervik, S.; Málek, T.; Pravda, V.; Pravdová, A.

    2015-12-01

    We study type II universal metrics of the Lorentzian signature. These metrics simultaneously solve vacuum field equations of all theories of gravitation with the Lagrangian being a polynomial curvature invariant constructed from the metric, the Riemann tensor and its covariant derivatives of an arbitrary order. We provide examples of type II universal metrics for all composite number dimensions. On the other hand, we have no examples for prime number dimensions and we prove the non-existence of type II universal spacetimes in five dimensions. We also present type II vacuum solutions of selected classes of gravitational theories, such as Lovelock, quadratic and L({{Riemann}}) gravities.

    2016-09-01

    We describe the universe as a single entangled ensemble of quantum particles. The total entropy of this world ensemble, which can be expressed as a sum of information, thermodynamic and entanglement components, is assumed to be always zero. This condition suggests information quantization, which we associate with the Planck's action. Then the entropy neutrality condition for the universe leads to the zero-action principle. We show that the main concepts of classical space-time and gravity naturally emerge in this picture. A generalized least action principle, which embraces the maximal entropy principles of information theory, is introduced.

    1993-01-01

    During the past decade, infrared observations by IRAS and from the ground have revealed that many stars are orbited by dusty debris disks. Somewhat more indirect arguments indicate that many of these systems also contain asteroids, comets, and/or planets, thereby suggesting that planetary systems may be quite common in the Milky Way. Dust clouds at the main sequence K5 star HD 98800 and the white dwarf Giclas 29-38 are particularly noteworthy and mysterious.

  1. [Building Process and Architectural Planning Characteristics of Daehan Hospital Main Building].

    PubMed

    Lee, Geauchul

    2016-04-01

    This paper explores the introduction process of Daehan Hospital from Japan as the modern medical facility in Korea, and the architectural planning characteristics as a medical facility through the detailed building process of Daehan Hospital main building. The most noticeable characteristic of Daehan Hospital is that it was designed and constructed not by Korean engineers but by Japanese engineers. Therefore, Daehan Hospital was influenced by Japanese early modern medical facility, and Japanese engineers modeled Daehan Hospital main building on Tokyo Medical School main building which was constructed in 1876 as the first national medical school and hospital. The architectural type of Tokyo Medical School main building was a typical school architecture in early Japanese modern period which had a middle corridor and a pseudo Western-style tower, but Tokyo Medical School main building became the model of a medical facility as the symbol of the medical department in Tokyo Imperial University. This was the introduction and transplantation process of Japanese modern 'model' like as other modern systems and technologies during the Korean modern transition period. However, unlike Tokyo Medical School main building, Daehan Hospital main building was constructed not as a wooden building but as a masonry building. Comparing with the function of Daehan Hospital main building, its architectural form and construction costs was excessive scale, which was because Japanese Resident-General of Korea had the intention of ostentation that Japanese modernity was superior to Korean Empire.

  8. The universal path integral

    NASA Astrophysics Data System (ADS)

    Lloyd, Seth; Dreyer, Olaf

    2016-02-01

    Path integrals calculate probabilities by summing over classical configurations of variables such as fields, assigning each configuration a phase equal to the action of that configuration. This paper defines a universal path integral, which sums over all computable structures. This path integral contains as sub-integrals all possible computable path integrals, including those of field theory, the standard model of elementary particles, discrete models of quantum gravity, string theory, etc. The universal path integral possesses a well-defined measure that guarantees its finiteness. The probabilities for events corresponding to sub-integrals can be calculated using the method of decoherent histories. The universal path integral supports a quantum theory of the universe in which the world that we see around us arises out of the interference between all computable structures.

  9. A Coronagraphic Survey for Circumstellar Disks Around Main Sequence and Pre-Main Sequence Stars

    NASA Astrophysics Data System (ADS)

    Kalas, Paul George

    1996-12-01

    We search for optical reflection nebulosity around ~100 main sequence and pre-main sequence stars to test the hypothesis that Vega-like stars possess replenished dust disks. A Lyot coronagraph is used to suppress light from the central star and to observe the circumstellar environment closer to planet-forming regions than is possible through direct imaging. A model of scattered light from axisymmetric circumstellar disks is developed to establish the sensitivity limits of our observations. Circumstellar nebulosities are detected around four main sequence stars: β Pic, BD +31o 643, HR 241, and HR 1307. No circumstellar disks are found around ~100 other main sequence stars, including Vega, Fomalhaut, HD 98800, HR 4796, and 51 Oph. Non-detections of disks in the main sequence sample, combined with the sensitivity limits, suggest that the optical scattering cross-section of dust at 102 - 103 AU radii is not strongly correlated to the thermal cross-section at 1-10 AU radii. We show that the prominence of the β Pic disk is primarily a result of its large scattering cross-section, rather than its edge-on inclination or close proximity to the Sun (Kalas & Jewitt 1996). Five types of asymmetry are identified and measured in the disk morphology (Kalas & Jewitt 1995). The observed tilt of the midplane may result from a small inclination (<= 5o) of the disk to our line of sight, combined with a non-isotropic scattering phase function. The remaining four asymmetries indicate a non-axisymmetric distribution of orbiting dust particles between 150 and 800 AU projected radius. The disk may have been gravitationally perturbed in the past 102 to 103 years, though a perturbing agent is not detected. A nebulosity imaged near the B5V double star BD +31o 643 is identified as a circumstellar disk candidate based on its morphological similarity to β Pic and our model disks (Kalas & Jewitt 1997). The disk has a position angle 131o, a projected radius of ~2000 AU, an inclination of i

    This talk will introduce the Cyclic Model of the Universe, a radical alternative to standard big bang/inflationary cosmology in which space and time exist indefinitely, high energy inflation is avoided, dark energy is given a prominent role, and the universe undergoes periodic epochs of expansion and cooling. The model, which is motivated by recent ideas in superstring theory, seems capable of reproducing all of the successes of the standard picture and leads to distinctive predictions.

    The principal objectives of the Fossil Energy Program are to seek new ideas, new data, fundamental knowledge that will support the ongoing programs, and new processes to better utilize the nation's fossil energy resources with greater efficiency and environmental acceptability. Toward this end, the Department of Energy supports research projects conducted by universities and colleges to: Ensure a foundation for innovative technology through the use of the capabilities and talents in our academic institutions; provide an effective, two-way channel of communication between the Department of Energy and the academic community; and ensure that trained technical manpower is developed to carry out basic and applied research in support of DOE's mission. Fossil Energy's university activities emphasize the type of research that universities can do best - research to explore the potential of novel process concepts, develop innovative methods and materials for improving existing processes, and obtain fundamental information on the structure of coal and mechanisms of reactions of coal, shale oil, and other fossil energy sources. University programs are managed by different Fossil Energy technical groups; the individual projects are described in greater detail in this book. It is clear that a number of research areas related to the DOE Fossil Energy Program have been appropriate for university involvement, and that, with support from DOE, university scientific and technical expertise can be expected to continue to play a significant role in the advancement of fossil energy technology in the years to come.

    Hands-on Universe is a project born at UC@Berkeley. A project devoted to enrich the teaching of Astronomy within the classroom environment with a different approach, more connected to the new technologies. Its main goals are not only to promote the use of such technologies but also to reawaken on students the taste for STEM (Science, technologies, engineering and math) related issues and also to increase their scientific culture. Eight countries in Europe decided to adopt the method and, funded by MINERVA, formed the European Hands-on Universe. Several resources were produced and a data reduction software developed http://www.euhou.net/.Other European countries are interested and should join this coordinated effort in the near future. At an international level there are 20 countries using this approach. There are plans to develop scientific cooperation among these countries. Pilot scientific research projects in schools are being tested in EU-HOU schools, Russia and USA. There is also a game being developed to be used as a new tool for teaching scientific content in the classroom environment. An effort to develop an international network of scientific / educational collaboration is the next step.

  19. Universality in Protein Residue Networks

    PubMed Central

    Estrada, Ernesto

    2010-01-01

    Abstract Residue networks representing 595 nonhomologous proteins are studied. These networks exhibit universal topological characteristics as they belong to the topological class of modular networks formed by several highly interconnected clusters separated by topological cavities. There are some networks that tend to deviate from this universality. These networks represent small-size proteins having <200 residues. This article explains such differences in terms of the domain structure of these proteins. On the other hand, the topological cavities characterizing proteins residue networks match very well with protein binding sites. This study investigates the effect of the cutoff value used in building the residue network. For small cutoff values, <5 Å, the cavities found are very large corresponding almost to the whole protein surface. On the contrary, for large cutoff value, >10.0 Å, only very large cavities are detected and the networks look very homogeneous. These findings are useful for practical purposes as well as for identifying protein-like complex networks. Finally, this article shows that the main topological class of residue networks is not reproduced by random networks growing according to Erdös-Rényi model or the preferential attachment method of Barabási-Albert. However, the Watts-Strogatz model reproduces very well the topological class as well as other topological properties of residue network. A more biologically appealing modification of the Watts-Strogatz model to describe residue networks is proposed. PMID:20197043

    1986-12-01

    This paper is a review of a number of publications during the last ten years about those changes in our views of the cosmic environment that are the result of advances in plasma physics. To a large extent, these originate from new observational material that space research has supplied. An attempt is made to construct a model of the ''plasma universe'' which is claimed to be an alternative to the traditional ''visual universe'' based mainly on observations in the visual octave. Besides the Hubble expansion there is also a ''knowledge expansion,'' which means that knowledge originating from plasma experiments in the laboratory is spreading to the magnetospheres and, it is predicted, sooner or later will also penetrate astrophysics in general. As an example of the usefulness of this model, it is applied to cosmogony, and a review is given of new results from an analysis of the Saturnian rings. The recent reconstruction of certain cosmogonic events with an accuracy better than 1 percent is reviewed and developed.

  1. [The preceptor in medical residencies in Pediatrics: main attributes

    2000-01-01

    OBJECTIVE: To analyze the profile of the preceptors and the attributes they consider important for the exercise of that activity, in two medical residency programs in Pediatrics in Rio de Janeiro METHODS: Through a questionnaire answered by each of the preceptors in two medical residency programs in Pediatrics in Rio de Janeiro, one of them connected to a university and the other one not, information was obtained on gender, age, time since graduation, how long they have been acting as preceptors, graduation titles, specific teaching training, and the listing of up to five attributes believed to be necessary to a good preceptor. The results were consolidated and discussed in the text. RESULTS: Of the 90 participants, 70% were woman, 74% were between 30 and 49 years old, 87% graduated between 10 and 29 years ago. Half of them said they did not have any specific teaching training and the other half had attended courses on Medical Pedagogy and Special Didactics during their respective graduate studies. The attribute categories most frequently mentioned were the exercise of tutorship, Ethics and Humanism, mastery of the subject area, capacity of permanent education, and didactic abilities. CONCLUSION: The preceptors pointed to the challenge of exercising preceptorship based on a medical practice where professional responsibilities, human relationship, organizational skills, evaluation techniques, and mastery of the subject area make the main guiding axes of the practice itself. To these axes they added the ethical and humanistic aspects and their permanent education capacities. They feel, however, the need for a didactic qualification in order to accomplish their duties.

The Universe Revealed provides the keys to unlocking the wonders of the cosmos. Elegantly written and lavishly illustrated, it begins with the Sun and stretches through our solar system into deepest space. Lucid prose, written by many of the people who have shaped our current thinking on space, and spectacular photographs make the physics of the Universe accessible and provide a solid background for understanding the most recent astronomical discoveries. Covering the most intriguing features of the cosmos, the topics discussed range from the Earth and global warming to cosmic collisions and the size of the Universe. Major sections examine the Solar System, stars, galaxies, cosmology, and the observational techniques used by astronomers, both amateur and professional. The Universe Revealed represents the collaboration of internationally renowned experts in astronomy and cosmology, with contributions from authors including David Malin, F. Duccio Macchetto, Iain Nicholson, Neil Bone, Ian Ridpath, Seth Shostak, Mike Lancaster, Steve Miller, Ken Croswell, Geoff McNamara, and Steven Young. This extraordinary blend of astronomy, astrophysics, and cosmology, will appeal to amateur and armchair astronomers alike.

    Universal planetary tectonics (supertectonics) G. Kochemasov IGEM of the Russian Academy of Sciences, Moscow, Russia, kochem.36@mail.ru The wave planetology [1-3 & others] proceeds from the following: "planetary structures are made by orbits and rotations". A uniform reason makes uniform structures. Inertia-gravity waves arising in planetary bodies due to their movements in Keplerian elliptical orbits with periodically changing accelerations warp these bodies in such way that they acquire polyhedron shapes (after interference of standing waves of four directions). Strong Newtonian gravity makes bodies larger than ~400 to 500 km in diameter globular and polyhedra are rarely seen. Only geomorphologic, geologic and geophysical mapping can develop these hidden structures. But small bodies, normally less than ~ 300 to 400 km in diameter, often show parts of the polyhedra, rarely fully developed forms (the asteroid Steins and satellite Amalthea present rather perfect forms of "diamond"). Depending on warping wavelengths (they make harmonics) various Plato's figures superimposed on each other can be distinguished. The fundamental wave 1 produces a tetrahedron, intrinsically dichotomic figure in which a vertex (contraction) always is opposed to a face (expansion). From the recent examples the best is the saturnian northern hexagon (a face) opposed to the southern hurricane (a vertex). The first overtone wave 2 is responsible for creation of structural octahedra. Whole ‘diamonds" and their parts are known [4, 5]. Other overtones produce less developed (because of smaller wave amplitudes) planetary shapes complicating main forms. Thus, the first common structural peculiarity of planetary bodies is their polyhedron nature. Not less important is the second common structural peculiarity. As all globular or smaller more or less isometric bodies rotate, they have an angular momentum. It is inevitably different in tropic and extra-tropic belts having uneven radii or distances to

  13. Submillimeter Imaging of Dust Around Main Sequence Stars

    Jewitt, David

    1998-01-01

    This grant was to image circumstellar dust disks surrounding main-sequence stars. The delivery of the SCUBA detector we had planned to use for this work was delayed repeatedly, leading us to undertake a majority of the observations with the UKT14 submillimeter detector at the JCMT (James Clerk Maxwell Telescope) and optical imagers and a coronagraph at the University of Hawaii 2.2-m telescope. Major findings under this grant include: (1) We discovered 5 asymmetries in the beta Pictoris regenerated dust disk. The discovery of these asymmetries was a surprise, since smearing due to Keplerian shear should eliminate most such features on timescales of a few thousand years. One exception is the "wing tilt" asymmetry, which we interpret as due to the scattering phase function of dust disk particles. From the wing tilt and a model of the phase function, we find a disk plane inclination to the line of sight of < 5 degrees. Other asymmetries (e.g. the butterfly asymmetry) suggest a disk that has been recently disturbed. We searched for possible nearby perturbers but found no clear candidates. Low mass stars (M dwarfs) and brown dwarfs would have fallen beneath the sensitivity threshhold of our survey, however. (2) We calculated a set of disk models to assess the detectability of dust disks around stars as a function of (a) distance, (b) disk, inclination (c) dust optical depth/mass, and (d) imaging resolution. These models guided our observational strategy on Mauna Kea. (3) We performed a coronagraphic survey of approx. 100 main-sequence stars in search of additional examples of circumstellar disks. The best new candidate disk, around the 5 M(sun) star BD+31deg.643, is distinguished by its large extent (few x 10( exp 3) AU). This disk, if real, cannot be rotationally supported. We suggest that the dust particles are ejected from a smaller, unseen disk (Kuiper Belt?) by strong radiation pressure forces due to the high luminosity central star. (4) SCUBA images of

    We exploit the parallel between dynamical black holes and cosmological spacetimes to describe the evolution of Friedmann-Lemaître-Robertson-Walker universes from the point of view of an observer in terms of the dynamics of the apparent horizon. Using the Hayward-Kodama formalism of dynamical black holes, we clarify the role of the Clausius relation to derive the Friedmann equations for a Universe, in the spirit of Jacobson’s work on the thermodynamics of spacetime. We also show how dynamics at the horizon naturally leads to the quantum-mechanical process of Hawking radiation. We comment on the connection of this work with recent ideas to consider our observable Universe as a Bose-Einstein condensate and on the corresponding role of vacuum energy.

  15. A Non Singular Universe

    NASA Astrophysics Data System (ADS)

    Hawking, Stephen

    2005-01-01

    The last chapter of my PhD thesis, contained my first singularity theorem. This showed that under certain reasonable conditions, any cosmological solution of the field equations, would have a big bang singularity. At this singularity, classical general relativity would break down, so one could not use it to predict how the universe began. It was therefore necessary to develop a quantum theory of gravity, in order to understand the origin of the universe. In this talk, I explore if the origin of the universe can be semi classical, and non singular. This is possible despite the singularity theorems, because like so many other no go theorems, they have a get out clause. In this case, the get out is the strong energy condition.

While the supernova can be seen, it cant be heard, as sound waves cannot travel through space. But what if the light waves emitted by the exploding star and other cosmological phenomena could be translated into sound?

    Bjorken, J.D.

    2004-02-18

    We define a universe as the contents of a spacetime box with comoving walls, large enough to contain measurable phenomena, but not much larger. This allows the construction of a local ensemble of such universes, given modest extrapolations of the observed properties of the cosmos. We then assume that further out similar universes can be constructed, but with different standard model parameters, strongly correlated with the size in a definite way, where by size is meant the Hubble scale at late times. This allows an estimate of the range of sizes supporting life as we know it. The result allows some understanding of the hierarchy problems of particle physics. Other possible implications of the assumptions made will be discussed, including a possible connection between the QCD vacuum structure and cosmological horizon structure. In all cases, our approach is as bottoms-up and as phenomenological as possible, suggesting that theories of the multiverse may eventually lay some claim of being scientific.

    We introduce ``anamorphic'' cosmology, an approach for explaining the smoothness and flatness of the universe on large scales and the generation of a nearly scale-invariant spectrum of adiabatic density perturbations. The defining feature is a smoothing phase that acts like a contracting universe based on some Weyl frame-invariant criteria and an expanding universe based on other frame-invariant criteria. An advantage of the contracting aspects is that it is possible to avoid the multiverse and measure problems that arise in inflationary models. Unlike ekpyrotic models, anamorphic models can be constructed using only a single field and can generate a nearly scale-invariant spectrum of tensor perturbations. Anamorphic models also differ from pre-big bang and matter bounce models that do not explain the smoothness. We present some examples of cosmological models that incorporate an anamorphic smoothing phase.

    Throughout the twentieth century, from the furor over Percival Lowell's claim of canals on Mars to the sophisticated Search for Extraterrestrial Intelligence, otherworldly life has often intrigued and occasionally consumed science and the public. The Biological Universe provides a rich and colorful history of the attempts during the twentieth century to answer questions such as whether "biological law" reigns throughout the universe and whether there are other histories, religions, and philosophies outside those on Earth. Covering a broad range of topics, including the search for life in the solar system, the origins of life, UFOs, and aliens in science fiction, Steven J. Dick shows how the concept of extraterrestrial intelligence is a world view of its own, a "biophysical cosmology" that seeks confirmation no less than physical views of the universe. This book will fascinate astronomers, historians of science, biochemists, and science fiction readers.

    The question of identifying the properties of language that are specific human linguistic abilities, i.e., Universal Grammar, lies at the center of linguistic research. This paper argues for a largely Emergent Grammar in phonology, taking as the starting point that memory, categorization, attention to frequency, and the creation of symbolic systems are all nonlinguistic characteristics of the human mind. The articulation patterns of American English rhotics illustrate categorization and systems; the distribution of vowels in Bantu vowel harmony uses frequencies of particular sequences to argue against Universal Grammar and in favor of Emergent Grammar; prefix allomorphy in Esimbi illustrates the Emergent symbolic system integrating phonological and morphological generalizations. The Esimbi case has been treated as an example of phonological opacity in a Universal Grammar account; the Emergent analysis resolves the pattern without opacity concerns. PMID:26388791
