    This paper presents a summary of the proceedings of a workshop on the Lakes of the Jordan Rift Valley that was held in conjunction with the CRP on The Use of Isotope Techniques in Lake Dynamics Investigations. The paper presents a review of the geological, hydrogeological and physical limnological setting of the lakes in the Jordan Rift Valley, Lake Hula, Lake Kinneret and the Dead Sea. This is complemented by a description of the isotope hydrology of the system that includes the use of a wide range of isotopes: oxygen-18, deuterium, tritium, carbon-14, carbon-13, chlorine isotopes, boron-11 and helium-3/4. Environmental isotope aspects of the salt balances of the lakes, their palaeolimnology and biogeochemical tracers are also presented. The scope of application of isotopic tracers is very broad and provides a clear insight into many aspects of the physical, chemical and biological limnology of the Rift Valley Lakes. (author)

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

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

    Full Text Available In a survey conducted in 2002 and 2003, Citrus tristeza virus (CTV was detected in the Jordan Valley. The direct tissue blot immunoassay (DTBIA indicated that 12.7 and 15.2% of samples tested in the central and northern Jordan Valley respectively were infected with CTV. Similar results showed that all citrus species grown in the Jordan Valley were susceptible to CTV. DAS-ELISA analysis of samples from a citrus orchard in the Dir Alla area with severe CTV symptoms indicated that 49% of samples were infected with CTV. Using a CTV specific primer pair (CTV1/CTV10, the coat protein gene of the virus was successfully amplified from leaf extracts obtained from CTVinfected trees by IC-RT-PCR. After cloning and sequencing the coat protein gene, the sequence of the amplified product was deposited in the GenBank.

    This report summarizes the results of the spatial risk modeling activities (work package WP-4.4, 'GIS Risk Modeling') of the INCO-DC project 'Developing Sustainable Water Management in the Jordan Valley'. The project was funded by European Commission's INCO-DC research program. The main objective of the project was to develop the scientific basis for an integral management plan of water resources and their use in the Lower Jordan Valley. The outputs of the project were expected to allow a better understanding of the water management situation, and to provide a sound basis for a better future water management - not only separately in the three countries, but in the overall valley region. The risk modeling was done by the ARCS Seibersdorf research (ARCS), based on information and data provided by the regional partners from Israel (Hebrew University, Jerusalem, HUJ), Palestine (Applied Research Institute, Jerusalem, Bethlehem, ARIJ) and Jordan (EnviroConsult Office, Amman, ECO). The land use classification has been established through a cooperation between ARCS and the Yale University Center for Earth Observation (YUCEO). As a result of the work, the spatial patterns of agricultural and domestic water demand in the Lower Jordan Valley were established, and the spatial dimension of driving forces for water usage and water supply was analyzed. Furthermore, a conceptual model for nitrate leakage (established by HUJ) was translated into a GIS system, and the risks for nitrate pollution of groundwater were quantified. (author)

  7. Salts in the dry valleys of Antartica

    The Dry Valleys of Antarctica are examples of polar deserts which are rare geological features on the Earth. Such deserts typically have high salinities associated with their closed-basin waters and on many surficial materials throughout them. In order to examine the possible sources for the salts observed in association with the soils in the Dry Valleys. The chloride and bromide concentrations of the water leachates from 58 soils and core samples were measured. The Cl/Br ratio for seawater is 289 and ratios measured for most of the 58 soils studied (greater than 85% of the soils studied) was larger than the seawater ratio (ratios typically were greater than 1000 and ranged up to 50,000). The enrichment in Cl relative to Br is strong evidence that the alts present within the soils were derived from seawater during ordinary evaporation processes, and not from the deposition of Cl and Br from aerosols or from rock weathering as has often been suggested.

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

    Lake Tiberias is a fresh water lake located at the Kinneret basin which is approximately 30 km long and 10 km wide. It comprises a link in the chain of pull-apart basins that characterizes the structure of the conspicuous Jordan Rift Valley (JRV). The basin surface is about 200 m below mean sea level (msl) and basin-fill attains a thickness of up to 8 km. Until recently, studies focused mainly on the upper strata of basin fill. Consequently, a complete three dimensional geological model, including clear view of the tectonic framework at the Kinneret Basin was incomplete. This situation imposes great difficulty in understanding the local hydrological system and as consequence enforce constrains on groundwater management of the regional aquifers that flows towards the lake. A recently proposed structural/tectonical model (Inbar, 2012) enables revaluation of several geohydrological aspects at Sea of Galilee and its surroundings and a new hydrological model based on those findings aims to clarify those aspects with relation to groundwater management. The deep-seated stratigraphical units were seismically studied at the Kinnarot Valley (southern part of Kinneret basin) where sufficient information is available (Inbar, 2012). This study shows the subsidence and northwestward tilting of the basin floor (pre-rift formations) and the flow of thick Late Miocene salt accumulation accordingly. Furthermore, shallower seismic data, collected at the lake itself, shows a suspected salt dome close to the western boundary fault of the basin (Resnikov et al., 2004). Salt flow is now suggested to be a substantial factor in the tectonic play. At the lake surroundings there are several springs and boreholes where brine immerges from an estimated depth of about 2-3 kilometers. Significant differences in brine characteristics raised questions regarding the location of brine traps, flow mechanism and the mixture process between the fresh water and the brine. However, the effect of the

    The Lower Jordan Valley is part of the Jordan-Dead Sea Rift. The graben is filled by sedmiments of limnological and marine origin. Towards the Dead Sea, the occurance of gipseous and salty sediments on the valley floor increase. The southern part of the Lower Jordan Valley, where the city of Jericho is situated, is an arid area (SMART-project, is to understand the vulnerability of the Jericho groundwater aquifers in connection with lowering the groundwater table by overexploitation and the intensively use of pesticides Jericho and its vicinity are of most importance for the Palestinians. However, beside the about 25,000 residents, the tourism industry and the vital agriculture depend on sufficient and expoitable fresh water resources. Because the demand of water is increasing, overexpoitaion takes place. Due to over extraction of groundwater a huge depression cone is evolving during the dry season which is filled up again according to the groundwater recharge in the rainy season. Concomitantly, depression cone in the fresh water aquifers leads to an infiltration of the surrounding saltwater. The amount of saltwater which infiltrates into the freshwater resource was calculated by different stable isotope methods (d2H, d18O) and hydrochemical analyses of wellwater. The agriculture is main consumer of groundwater - over 60% of the pumped water is used for inefficient irrigation. Additionally, an intensive use of pesticides in concentrated liquid and gaseous forms for vegetable gardening hold the danger to pollute the groundwater via irrigation return flow. This return flow most probably endangers the quality of the water resource, because shallow wells nearby extract it directly from the underground. However, one result of the first screening campaign concerning pesticide remnants in the groundwater wells of Jericho, just traces have been detected. Thus, the higher amount of chemicals is retained by the soil during infiltration of irrigated water. The detected low

    Full Text Available Installation of decentralized grey water treatment systems in small rural communities contributes to a more sustainable water supply. In order to gauge community attitudes about collection and use of grey water, a door-to-door survey in the farming community of Deir Alla, Jordan was conducted by Royal Scientific Society interviewers. Outcomes of a detailed survey, designed specifically for this project, offer insights on people’s views on general water and wastewater issues, as well as their motivation, practices and concerns related to using grey water treatment for a portion of their household wastewater and reuse of the treated grey water for irrigation. A total of 47 respondents from different socio-economic background, aged over 18 years, from this community in the Jordan valley took part in the survey. The level of formal education of the respondents was low, and most of households’ incomes were below the poverty line in Jordan. Most of the respondents reported that the quality of water supplied by public network is acceptable, but the quantity is insufficient to meet their demand, with supplies being delivered to the household once a week. Respondents relied on the public water network as a first-most important resource (85.1%, and 57.4% of the respondent relied on private water tankers as a second-most important resource in addition to the public network. However, 6% of the respondents relied only on private water tankers with no access to the public network. Storage tanks are common practice in all the houses in order to store enough water for at least one week. The survey responses provide evidence that rural communities are willing to accept reuse of treated grey water for irrigation. Furthermore, some of people in the studied area are willing to learn more about grey water treatment and reuse in order to operate grey water systems for irrigation purposes. Water scarcity in this rural area of Jordan is the main determinant of

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

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

    Treatment and control of hypertension (HTN) is a challenging issue as undiagnosed HTN prevalence seems to be high among certain ethnic groups, such as African-descendant populations. The current study attempted to measure HTN prevalence, awareness and control levels among Ghawarna, an African-descendant ethnic group living in the Jordan Valley (Al-Ghawr). A cross-sectional study was conducted in a community of Ghawarna between March and June 2013 in Ghawr Al-Mazraa Village in the southern part of the Jordan Valley. A total of 517 participants, aged >25 years, were randomly selected using cluster random sampling technique. Data were collected using an interviewer-administrated questionnaire and on-location measurement of blood pressure (BP), height, and weight. Prevalence rates were compared by sex and age groups using chi-square test while backward selection logistic regression analysis was used to identify predictors of HTN. We found 229 (44.3%) of the 517 participants had HTN. Of those 229 hypertensives, 146 (28.2%) participants were discovered to have HTN for the "first time." Only 23 of the 83 who were aware of their hypertension had their BP controlled. When we added the undiagnosed HTN (n=146) to the uncontrolled HTN (n=60), the prevalence of uncontrolled HTN became 90% (206/229). Older age, higher BMI, diabetes mellitus, and dyslipidemia were associated with having HTN. HTN prevalence, awareness and control levels are alarming among Ghawarna.

    High dietary sodium is recognized as a silent killer responsible for 2.3 million deaths worldwide in 2010 predominantly secondary to hypertension and its complications. Although high salt consumption is considered a worldwide public health problem, its magnitude is highly variable among different communities; therefore, it is important to study locally. This study aimed to evaluate habitual salt consumption, its important correlations, as well as the knowledge, attitude, and behavior of healthy Jordanian citizens. As potassium consumption is highly correlated and important we aimed to study both jointly. In this descriptive cross-sectional study we enrolled 103 healthy adult Jordanian citizens. All participants were interviewed for questionnaire filling, physical examination, and instructed on proper 24-hour urine collection procedure. We measured sodium and potassium concentration in the provided controlled 24-hour urine collection samples, as it is presently considered the gold standard for evaluating daily intake. The results showed an average sodium intake of 179 mmol (4.1 g) per day [higher in males at 186 mmol (4.3 g) vs. 173 mmol (4.0 g) for females], significantly above the current WHO recommendations, though only 8% regularly add salt to food. Ironically, most participants (82%) believe their salt consumption was appropriate and only 29% thought they may benefit from reducing salt intake. On the other hand, potassium intake is far below the current WHO recommendations. High sodium and low potassium intake have synergistic adverse effects on public health that is not currently addressed in Jordan. We conclude that Jordanian citizens currently consume high sodium and low potassium diet and are mostly unaware of its negative impact on their health. Hence, it is crucial for healthcare providers to intervene and adopt long-term strategies to control salt intake to reduce its negative effects in Jordan and elsewhere.

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

    The geology and hydrology of a portion of the Salt Valley anticline lying north of Moab, Utah, that is being studied as a potential site for underground storage of nuclear waste in salt are discussed. Selection of this area was based on recommendations made in an earlier appraisal of the potential of Paradox basin salt deposits for such use. Salt Valley anticline, a northwest-trending diapiric structure, consists of Mesozoic sedimentary rocks arched over a thick core of salt of the Paradox Member of the Middle Pennsylvanian Hermosa Formation. Salt began to migrate to form and/or develop this structure shortly after it was deposited, probably in response to faulting. This migration caused upwelling of the salt creating a linear positive area. This positive area, in turn, caused increased deposition of sediments in adjacent areas which further enhanced salt migration. Not until late Jurassic time had flowage of the salt slowed sufficiently to allow sediments of the Morrison and younger formations to be deposited across the salt welt. A thick cap of insoluble residue was formed on top of the salt diapir as a result of salt dissolution through time. The crest of the anticline is breached; it collapsed in two stages during the Tertiary Period. The first stage was graben collapse during the early Tertiary; the second stage occurred after Miocene regional uplift had caused downcutting streams to breach the salt core resulting in further collapse. The axis of the anticline is a narrow generally flat-floored valley containing a few hills composed of downdropped Mesozoic rocks foundered in thecaprock. The caprock, which underlies thin alluvium in the valley, is composed of contorted gypsum, shale, sandstone, and limestone--the insoluble residue of the Paradox salt

The results of these studies will be used to help to determine the suitability of salt deposits in the Paradox basin as a storage medium for radioactive waste material.

    Surface landforms in the Salt Valley Area are generally a function of the Salt Valley anticline and are characterized by parallel and subparallel cuestaform ridges and hogbacks and flat valley floors. The most prominent structure in the Area is the Salt Valley anticline. Erosion resulting from the Tertiary uplift of the Colorado Plateau led to salt dissolution and subsequent collapse along the crest of the anticline. Continued erosion removed the collapse material, forming an axial valley along the crest of the anticline. Paleozoic rocks beneath the salt bearing Paradox Formation consist of limestone, dolomite, sandstone, siltstone and shale. The salt beds of the Paradox Formation occur in distinct cycles separated by an interbed sequence of anhydrite, carbonate, and clastic rocks. The Paradox Formation is overlain by Pennsylvanian limestone; Permian sandstone; and Mesozoic sandstone, mudstone, conglomerate and shale. No earthquakes have been reported in the Area during the period of the historic record and contemporary seismicity appears to be diffusely distributed, of low level and small magnitude. The upper unit includes the Permian strata and upper Honaker Trail Formation. The current data base is insufficient to estimate ground-water flow rates and directions in this unit. The middle unit includes the evaporites in the Paradox Formation and no laterally extensive flow systems are apparent. The lower unit consists of the rocks below the Paradox Formation where permeabilities vary widely, and the apparent flow direction is toward the west. 108 refs., 39 figs., 9 tabs

    This report describes the geology and hydrology of a portion of the Salt Valley anticline lying north of Moab, Utah, that is being studied as a potential site for underground storage of nuclear waste in salt. Selection of this area was based on recommendations made in an earlier appraisal of the potential of Paradox basin salt deposits for such use. Part of sec. 5, T. 23 S., R. 20 E. has been selected as a site for subsurface investigation as a potential repository for radioactive waste. This site has easy access to transportation, is on public land, is isolated from human habitation, is not visible from Arches National Park, and the salt body lies within about 800 feet (244 m) of the surface. Further exploration should include investigation of possible ground water in the caprock and physical exploration of the salt body to identify a thick bed of salt for use as a storage zone that can be isolated from the shaly interbeds that possibly contain quantities of hydrocarbons. Salt Valley anticline, a northwest-trending diapiric structure, consists of Mesozoic sedimentary rocks arched over a thick core of salt of the Paradox Member of the Middle Pennsylvanian Hermosa Formation. Salt began to migrate to form and/or develop this structure shortly after it was deposited, probably in response to faulting. This migration caused upwelling of the salt creating a linear positive area. This positive area, in turn, caused increased deposition of sediments in adjacent areas which further enhanced salt migration. Not until late Jurassic time had flowage of the salt slowed sufficiently to allow sediments of the Morrison and younger formations to be deposited across the salt welt. A thick cap of insoluble residue was formed on top of the salt diapir as a result of salt dissolution through time. The crest of the anticline is breached; it collapsed in two stages during the Tertiary Period. The first stage was graben collapse during the early Tertiary; the second stage occurred after

    Regression models that relate total dissolved solids (TDS) concentrations to specific conductance were used to estimate salt loads for two sites on the Dolores River in the Paradox Valley in western Colorado. The salt-load estimates will be used by the Bureau of Reclamation to evaluate salt loading to the river coming from the Paradox Valley and the effect of the Paradox Valley Unit (PVU), a project designed to reduce the salinity of the Colorado River. A second-order polynomial provided the best fit of the discrete data for both sites on the river. The largest bias occurred in samples with elevated sulfate concentrations (greater than 500 milligrams per liter), which were associated with short-duration runoff events in late summer and fall. Comparison of regression models from a period of time before operation began at the PVU and three periods after operation began suggests the relation between TDS and specific conductance has not changed over time. Net salt gain through the Paradox Valley was estimated as the TDS load at the downstream site minus the load at the upstream site. The mean annual salt gain was 137,900 tons per year prior to operation of the PVU (1980–1993) and 43,300 tons per year after the PVU began operation (1997–2015). The difference in annual salt gain in the river between the pre-PVU and post-PVU periods was 94,600 tons per year, which represents a nearly 70 percent reduction in salt loading to the river.

    The Antarctic Dry Valleys represent a unique environment where it is possible to study dry permafrost overlaying an ice-rich permafrost. In this paper, two opposing mechanisms for ice table stability in University Valley are addressed: i) diffusive recharge via thin seasonal snow deposits and ii) desiccation via salt deposits in the upper soil column. A high-resolution time-marching soil and snow model was constructed and applied to University Valley, driven by meteorological station atmospheric measurements. It was found that periodic thin surficial snow deposits (observed in University Valley) are capable of drastically slowing (if not completely eliminating) the underlying ice table ablation. The effects of NaCl, CaCl2 and perchlorate deposits were then modelled. Unlike the snow cover, however, the presence of salt in the soil surface (but no periodic snow) results in a slight increase in the ice table recession rate, due to the hygroscopic effects of salt sequestering vapour from the ice table below. Near-surface pore ice frequently forms when large amounts of salt are present in the soil due to the suppression of the saturation vapour pressure. Implications for Mars high latitudes are discussed.

    Sandstones that overlie or that are interbedded with evaporitic or other ductile strata commonly contain numerous localized domains of fractures, each covering an area of a few square miles. Fractures within the Entrada Sandstone at the Salt Valley Anticline are associated with salt mobility within the underlying Paradox Formation. The fracture relationships observed at Salt Valley (along with examples from Paleozoic strata at the southern edge of the Holbrook basin in northeastern Arizona, a...

    1979-01-01

    The Bonneville Salt Flats and Pilot Valley are in the western part of the Great Salt Lake Desert in northwest Utah. The areas are separate, though similar, hydrologic basins, and both contain a salt crust. The Bonneville salt crust covered about 40 square miles in the fall of 1976, and the salt crust in Pilot Valley covered 7 square miles. Both areas lack any noticeable surface relief (in 1976, 1.3 feet on the Bonneville salt crust and 0.3 foot on the Pilot Valley salt crust).The salt crust on the Salt Flats has been used for many years for automobile racing, and brines from shallow lacustrine deposits have been used for the production of potash. In recent years, there has been an apparent conflict between these two major uses of the area as the salt crust has diminished in both thickness and extent. Much of the Bonneville Racetrack has become rougher, and there has also been an increase in the amount of sediment on the south end of the racetrack. The Pilot Valley salt crust and surrounding playa have been largely unused.Evaporite minerals on the Salt Flats and the Pilot Valley playa are concentrated in three zones: (1) a carbonate zone composed mainly of authigenic clay-size carbonate minerals, (2) a sulfate zone composed mainly of authigenic gypsum, and (3) a chloride zone composed of crystalline halite (the salt crust). Five major types of salt crust were recognized on the Salt Flats, but only one type was observed in Pilot Valley. Geomorphic differences in the salt crust are caused by differences in their hydrologic environments. The salt crusts are dynamic features that are subject to change because of climatic factors and man's activities.Ground water occurs in three distinct aquifers in much of the western Great Salt Lake Desert: (1) the basin-fill aquifer, which yields water from conglomerate in the lower part of the basin fill, (2) the alluvial-fan aquifer, which yields water from sand and gravel along the western margins of both playas, and (3) the

    In 1986 Los Alamos National Laboratory was engaged by the US Army to study the meteorological aspects of emergency preparedness at several sites where toxic materials are stored and handled. The project included a series of tracer and meteorological field experiments in the vicinity of the Tooele Army Depot. These experiments generated a large data set for validating numerical simulations and for empirical analyses of the local meteorology. This paper discusses the main characteristics of the daytime, up-valley flow at the Utah site, including frequency of occurrence, horizontal and vertical structure, and temporal evolution. Some parameters controlling the variability in onset time for up-valley flow are identified, and an empirical forecasting scheme is discussed. 16 refs., 7 figs.

    The Salt Valley anticline, which is located about 32 km northeast of Moab, Utah, is perhaps one of the most favorable waste emplacement sites in the Paradox basin. The site, which includes about 7.8 km 2, is highly accessible and is adjacent to a railroad. The anticline is one of a series of northwest-trending salt anticlines lying along the northeast edge of the Paradox basin. These anticlines are cored by evaporites of the Paradox Member of the Hermosa Formation of Middle Pennsylvanian age. The central core of the Salt Valley anticline forms a ridgelike mass of evaporites that has an estimated amplitude of 3,600 m. The evaporite core consists of about 87 percent halite rock, which includes some potash deposits; the remainder is black shale, silty dolomite, and anhydrite. The latter three lithologies are referred to as 'marker beds.' Using geophysical logs from drill holes on the anticline, it is possible to demonstrate that the marker beds are complexly folded and faulted. Available data concerning the geothermal gradient and heatflow at the site indicate that heat from emplaced wastes should be rapidly dissipated. Potentially exploitable resources of potash and petroleum are present at Salt Valley. Development of these resources may conflict with use of the site for waste emplacement.

    Full Text Available The faunal assemblage from the 9(th-8(th millennium BP site at Sha'ar Hagolan, Israel, is used to study human interaction with wild suids and cattle in a time period just before the appearance of domesticated animals of these species in the Jordan Valley. Our results, based on demographic and osteometric data, indicate that full domestication of both cattle and suids occurred at the site during the 8(th millennium. Importantly, domestication was preceded in both taxa by demographic and metric population parameters indicating severe overhunting. The possible role of overhunting in shaping the characteristics of domesticated animals and the social infrastructure to ownership of herds is then explored.

    The 12th century BCE was a period of turmoil in the Southern Levant. The Canaanite Late Bronze Age culture - during several hundred years dominated by Egypt - received quite abruptly strong influences from the Eastern Mediterranean. The bearer of these new cultural elements, the so called Sea Peoples who included the Philistines, settled in Palestine after attacking Egypt. The changes that took place in Palestine are best reflected in the material culture which demonstrates Aegean and Cypriote elements. The exact date of their arrival in Palestine is a matter of recurrent discussion but the majority of scholars agree that it happened in the 12th century BCE. Philistine culture is usually associated with the area around today's Gaza. Nevertheless, the current excavations at Tell Abu al- Kharaz in the Transjordanian Jordan Valley provide evidence of Eastern Mediterranean/Philistine culture and a number of radiocarbon dates from first class find contexts.

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

    A seismic-refraction survey, consisting of three lines about 2700, 2760, and 5460 meters long, was made at the north end of the Salt Valley anticline of the Paradox Basin in eastern Utah. The target was the crest of a diapiric salt mass and the overlying, deformed caprock. The interpretations reveal an undulating salt surface with as much as 80 meters of relief. The minimum depth of about 165 meters is near the location of three holes drilled by the U.S. Department of Energy for the purpose of evaluating the Salt Valley anticline as a potential site for radioactive waste storages Caprock properties were difficult to estimate because the contorted nature of these beds invalidated a geologic interpretation in terms of velocity layers. However, laterally varying velocities of the critically refracted rays throughout the area suggest differences in the gross physical properties of the caprock.

    Full Text Available This paper attempts to present and discuss the outcome of the results of the key different studies and projects carried out at Salt and at Irbid historic cores.  It focuses on the executed urban heritage projects undertaken mainly by the Ministry of Tourism and Antiquities (MoTA of Jordan in the last two decades. It discusses their different aspects through initial assessment of the loss and degradation of the cultural heritage assets of the two cities; the fragmentation and lack of connectivity between the modern and historic cores; issues of sustainability of architectural and urban heritage projects i.e. tourism planning and conservation; and reuse projects at the historic cores in relation to cultural, physical factors and development needs. It also addresses the behaviour and characteristics of the urban regeneration process in those two historic cities, starting from their documentation to examination of the different aspects of the currently adopted urban practices and policies, and their impact on the existing urban heritage, depending on the specific identity of the respective historic cores. Finally, it aims to define the main constraints and challenges for the reuse of the existing heritage fabric including the local community quality of life, while building on sustainable heritage activities accommodating tourism opportunities. This will give, at least, some indications from which we can identify a use or combination of uses, and practical steps needed for successful heritage conservation actions in Jordan, in order to retain the cultural significance of the place.

    1980-01-01

    Three exploratory drill holes were drilled at Salt Valley, Utah, to study the geologic, physical, geochemical, and hydrologic properties of the evaporite sequence in the Permian Paradox Member of the Hermosa Formation. The results of these studies will be used to help to determine the suitability of salt deposits in the Paradox basin as a storage medium for radioactive waste material. The following geophysical well-log measurements were made in each of the three drill holes: (1) density, (2) neutron, (3) acoustic velocity, (4) normal resistivity, and (5) gamma ray. Widely spaced resistivity and conductivity well-log measurements were made in the deep drill hole. Each of these well-log measurements shows the division of the evaporite sequence into halite and interbed sections. At the present time the most useful well-logging measurements for determining the individual lithologies in an evaporite sequence are gamma ray, neutron, density, and acoustic velocity. The high resistivity contrast between the drilling fluid (0.5 ohm-m) and salt (10,000 ohm-m) makes it difficult to obtain quantitative measurements of electrical properties in an evaporite sequence. Tests of widely spaced electrode configurations show that the effects of the brine on the resistivity measurements can be reduced, and the depth of investigation increased, by increasing the source-receiver electrode spacing. Tests of a single-coil induction probe show good resolution of the contrasting electrical properties of the various interbed lithologies

    Addressing the global challenges to water security requires a better understanding of humanity's use of water, especially the agricultural sector that accounts for 70% of global withdrawals. This study combined high resolution-data with a GIS system to analyze the impact of agricultural practices, crop type, and spatial factors such as drainage basins, climate, and soil type on the Water Footprint (WF) of agricultural crops. The area of the study, the northern Lower Jordan Valley, covers 1121 ha in which three main plantation crops are grown: banana (cultivated in open-fields or net-houses), avocado and palm-dates. High-resolution data sources included GIS layers of the cultivated crops and a drainage pipe-system installed in the study area; meteorological data (2000-2013); and crop parameters (yield and irrigation recommendations). First, the study compared the WF of the different crops on the basis of yield and energy produced as well as a comparison to global values and local irrigation recommendations. The results showed that net-house banana has the lowest WF based on all different criteria. However, while palm-dates showed the highest WF for the yield criteria, it had the second lowest WF for energy produced, emphasizing the importance of using multiple parameters for low and high yield crop comparisons. Next, the regional WF of each drainage basin in the study area was calculated, demonstrating the strong influence of the Gray WF, an indication of the amount of freshwater required for pollution assimilation. Finally, the benefits of integrating GIS and WF were demonstrated by computing the effect of adopting net-house cultivation throughout the area of study with a result a reduction of 1.3 MCM irrigation water per year. Integrating the WF methodology and local high-resolution data using GIS can therefore promote and help quantify the benefits of adopting site-appropriate crops and agricultural practices that lower the WF by increasing yield, reducing water

    A main focus of the recently awarded National Science Foundation (NSF) EPSCoR Track-1 research project "innovative Urban Transitions and Arid-region Hydro-sustainability (iUTAH)" is to quantify the primary components of the water balance for the Wasatch region, and to evaluate their sensitivity to climate change and projected urban development. Building on the multiple-box model that we developed and validated for carbon dioxide (Strong et al 2011), mass balance equations for water in the atmosphere and surface are incorporated into the modeling framework. The model is used to determine how surface fluxes, ground-water transport, biological fluxes, and meteorological processes regulate water cycling within and around the urban Salt Lake Valley. The model is used to evaluate the hypotheses that increased water demand associated with urban growth in Salt Lake Valley will (1) elevate sensitivity to projected climate variability and (2) motivate more attentive management of urban water use and evaporative fluxes.

  6. Thin, Conductive Permafrost Surrounding Lake Fryxell Indicates Salts From Past Lakes, McMurdo Dry Valleys, Antarctica

    In the McMurdo Dry Valleys (MDV), permafrost should be thick and liquid water rare. However, despite the well below zero mean annual temperature in this cryospheric desert, liquid water can be found in lakes, summer melt streams, subglacial outflow, and - recent work has shown - underneath anomalously thin permafrost. In part, this niche hydrosphere is maintained by the presence of salts, which depress the freezing point of water to perhaps as cold as -10° Celsius. We detected widespread salty water across the MDV in lakes and at depth using a helicopter-borne Time Domain Electromagnetic (TDEM) sensor. By using the presence of brines to mark the transition from frozen permafrost (near the surface) to unfrozen ground (at depth), we have created a map of permafrost thickness in Lower Taylor Valley (LTV), a large MDV with a complex history of glaciation and occupation by lakes. Our results show that permafrost is thinner ( 200m) than would be expected based on geothermal gradient measurements (up to 1000m), a result of the freezing point depression caused by salt and potentially enhanced by an unfinished transient freezing process. Near Lake Fryxell, a large, brackish lake in the center of LTV, permafrost is very thin (about 30-40m) and notably more electrically conductive than more distal permafrost. This thin ring of conductive permafrost surrounding the lake basin most likely reflects the high presence of salts in the subsurface, preventing complete freezing. These salts may be a remnant of the salty bottom waters of a historic larger lake (LGM glacially dammed Lake Washburn) or the remnant of salty basal water from a past advance of Taylor Glacier, which now sits many km up-valley but is known to contain brines which currently flow onto the surface and directly into the subsurface aquifer.

  7. Understanding the behavior of carbon dioxide and surface energy fluxes in semiarid Salt Lake Valley, Utah, USA

    Ramamurthy, Prathap

    This dissertation reports the findings from the Salt Lake Valley flux study. The Salt Lake Valley flux study was designed to improve our understanding of the complex land-atmosphere interactions in urban areas. The flux study used the eddy covariance technique to quantify carbon dioxide and surface energy budget in the semiarid Salt Lake Valley. Apart from quantifying fluxes, the study has also added new insight into the nature of turbulent scalar transport in urban areas and has addressed some of the complications in using Eddy Covariance technique in urban areas. As part of this experiment, eddy fluxes of CO2 and surface energy fluxes were measured at two sites, with distinct urban landforms; One site was located in a suburban neighborhood with substantial vegetative cover, prototypical of many residential neighborhoods in the valley. The other CO2 site was in a preurban surrounding that resembled the Salt Lake Valley before it was urbanized. The two sites were intentionally chosen to illustrate the impact of urbanization on CO 2 and surface energy flux cycles. Results indicate that the suburban site acted as a sink of CO2 during the midday period due to photosynthesis and acted as a source of CO2 during the evening and nighttime periods. The vegetative cover around the suburban site also had a significant impact on the surface energy fluxes. Contribution from latent heat flux was substantially high at the suburban site during the summer months compared to sensible heat. The turbulence investigation found that the general behavior of turbulence was very much influenced by local factors and the statistics did not always obey Monin-Obukhov Similarity parameters. This investigation also found that the scalar (co)spectra observed at the suburban site were characterized by multiple peaks and were different compared to (co)spectra reported over forest and crop canopies. The study also observed multiscale CO2 transport at the suburban site during the convective period

    Two thirds of the world's population relies on medicinal plants for centuries for several human pathologies. Present study aimed to identify, catalogue and document the large number of medicinal plants used in traditional medicine in Soan Valley, Salt Range, Pakistan. Informal interviews were conducted involving a total of 255 villagers (155 male and 65 female and 35 herbalists) to elicit the knowledge and use of medicinal plants. Local communities possessed knowledge of fifty eight (58) medicinal plant species belonging to thirty five (35) families to treat fifteen ailment categories. Whole plant and leaves were the most frequently used plant parts (24%) followed by seed (14%), root (12%), flower (7%), bulb (6%), fruit (4%), stem (3%), latex and rhizome (2%) and sap and gum (1%). Frequently used growth forms of medicinal plants were wild herbs (63%) followed by cultivated herbs (14%), wild trees (11%), wild shrubs (10%) and wild and cultivated herbs (2%). Preparations were administrated generally through oral and topical routes. Local people were familiar mostly with the species in order to deal common ailments particularly cough, cold, digestive problems, fever, headache, and skin infections. Complex ailments were treated by traditional healers. Justica adhatoda, Olea ferruginea, Amaranthus viridis and Mentha royleana were identified as plants with high use value (UV). This study revealed that the area harbors high diversity of medicinal flora. Despite gradual socio-cultural transformation, local communities still hold ample knowledge of plants and their uses. The reliance on traditional medicines was associated with the lack of modern health care facilities, poverty and the traditional belief of their effectiveness. Medicinal plants play a significant role in management of various human diseases in the study area. A high degree of consensus among the informants was an indicative that plant use and knowledge were still strong, and preservation of this knowledge

  10. Interpreting Fracture Patterns in Sandstones Interbedded with Ductile Strata at the Salt Valley Anticline, Arches National Park, Utah; TOPICAL

    Sandstones that overlie or that are interbedded with evaporitic or other ductile strata commonly contain numerous localized domains of fractures, each covering an area of a few square miles. Fractures within the Entrada Sandstone at the Salt Valley Anticline are associated with salt mobility within the underlying Paradox Formation. The fracture relationships observed at Salt Valley (along with examples from Paleozoic strata at the southern edge of the Holbrook basin in northeastern Arizona, and sandstones of the Frontier Formation along the western edge of the Green River basin in southwestern Wyoming), show that although each fracture domain may contain consistently oriented fractures, the orientations and patterns of the fractures vary considerably from domain to domain. Most of the fracture patterns in the brittle sandstones are related to local stresses created by subtle, irregular flexures resulting from mobility of the associated, interbedded ductile strata (halite or shale). Sequential episodes of evaporite dissolution and/or mobility in different directions can result in multiple, superimposed fracture sets in the associated sandstones. Multiple sets of superimposed fractures create reservoir-quality fracture interconnectivity within restricted localities of a formation. However, it is difficult to predict the orientations and characteristics of this type of fracturing in the subsurface. This is primarily because the orientations and characteristics of these fractures typically have little relationship to the regional tectonic stresses that might be used to predict fracture characteristics prior to drilling. Nevertheless, the high probability of numerous, intersecting fractures in such settings attests to the importance of determining fracture orientations in these types of fractured reservoirs

    The results from a geologic investigation of the Virgin River Valley salt deposits, Clark County, southeastern Nevada, to examine their suitability for further study and consideration in connection with the possible storage of radioactive waste material are given. The results indicate that (1) approximately one-half of the salt body underlies the Overton Arm of Lake Mead and that the dry land portion of the salt body that has a thickness of 1,000 feet or more covers an area of about four and one-half square miles; (2) current tectonic activity in the area of the salt deposits is believed to be confined to seismic events associated with crustal adjustments following the filling of Lake Mead; (3) detailed information on the hydrology of the salt deposit area is not available at present but it is reported that a groundwater study by the U.S. Geological Survey is now in progress; (4) there is no evidence of exploitable minerals in the salt deposit area other than evaporites such as salt, gypsum, and possibly sand and gravel; (5) the salt deposit area is located inside the Lake Mead Recreation Area, outlined on the accompanying Location Plat, and several Federal, State, and Local agencies share regulatory responsibilities for the activities in the area; (6) other salt deposit areas of Arizona and Nevada, such as the Detrital Valley, Red Lake Dome, Luke Dome, and Mormon Mesa area, and several playa lake areas of central Nevada may merit further study; and (7) additional information, as outlined, is needed to more thoroughly evaluate the salt deposits of the Virgin River Valley and other areas referred to above

    The Jurassic Smackover Interior Salt Basins Total Petroleum System is defined for this assessment to include (1) Upper Jurassic Smackover Formation carbonates and calcareous shales and (2) Upper Jurassic and Lower Cretaceous Cotton Valley Group organic-rich shales. The Jurassic Smackover Interior Salt Basins Total Petroleum System includes four conventional Cotton Valley assessment units: Cotton Valley Blanket Sandstone Gas (AU 50490201), Cotton Valley Massive Sandstone Gas (AU 50490202), Cotton Valley Updip Oil and Gas (AU 50490203), and Cotton Valley Hypothetical Updip Oil (AU 50490204). Together, these four assessment units are estimated to contain a mean undiscovered conventional resource of 29.81 million barrels of oil, 605.03 billion cubic feet of gas, and 19.00 million barrels of natural gas liquids. The Cotton Valley Group represents the first major influx of clastic sediment into the ancestral Gulf of Mexico. Major depocenters were located in south-central Mississippi, along the Louisiana-Mississippi border, and in northeast Texas. Reservoir properties and production characteristics were used to identify two Cotton Valley Group sandstone trends across northern Louisiana and east Texas: a high-permeability blanket-sandstone trend and a downdip, low-permeability massive-sandstone trend. Pressure gradients throughout most of both trends are normal, which is characteristic of conventional rather than continuous basin-center gas accumulations. Indications that accumulations in this trend are conventional rather than continuous include (1) gas-water contacts in at least seven fields across the blanket-sandstone trend, (2) relatively high reservoir permeabilities, and (3) high gas-production rates without fracture stimulation. Permeability is sufficiently low in the massive-sandstone trend that gas-water transition zones are vertically extensive and gas-water contacts are poorly defined. The interpreted presence of gas-water contacts within the Cotton Valley

    Aquifer skeletons deform actively in response to the groundwater redistribution and hydraulic head changes with varied time scales of delay and sensitivity, that can also, in some instances, trigger earthquakes. However, determining the key hydrogeological properties and understanding the interactions between aquifer and seismicity generally requires the analysis of dense water level data combined with expensive drilling data (borehole breakouts). Here we investigate the spatiotemporal correlation among ground motions, hydrological changes, earthquakes, and faults in Salt Lake Valley, Utah, based on InSAR observations from ENVISAT ASAR (2004-2010) and Sentinel-1A (2015-2016). InSAR results show a clear seasonal and long-term correlation between surface uplift/subsidence and groundwater recharge/discharge, with evidence for an average net uplift of 15 mm/yr for a period of 7 years. The long-term uplift, remarkably bounded by faults, reflects a net increase in pore pressure associated with prolonged water recharge probably decades ago. InSAR-derived ground deformation and its correlation with head variations allow us to quantify hydrogeological properties - decay coefficient, storage coefficient, and bulk compressibility. We also model the long-term deformation using a shallow vertical shearing reservoir to constrain its thickness and strain rate. InSAR-derived deformation help reveal the coupled hydrological and tectonic processes in Salt Lake Valley: the embedded faults disrupt the groundwater flow and partition the hydrological units, and the pore pressure changes rearrange the aquifer skeleton and modulate the stress field, which may affect the basin-wide seismicity.

    The Bet She’an and Harod Valleys in Israel are regional recipients and mixing zones for groundwater draining from a multiple aquifer system, which includes carbonate and basalt aquifers and deep-seated pressurized brines. The aquifers drain through two types of outlets, distinct and mixed. The latter type is mainly conditioned by the occurrence of fault-blocks related to the Jordan Rift system, which act as connecting media between the aquifers and facilitate interaquifer flow. Conjoint application of rare earth element distribution and water isotopes enables detection of the local areas replenishment by rainfall infiltration and, in connection with the position of wells or springs, the identification of groundwater flow paths. Once stationary equilibria are established changes of REY composition between REY in groundwater and their surface adsorption, are negligible. In areas with little soil coverage and vegetation even recharge over young Tertiary and diagenetic Cretaceous limestones is distinguishable by their REY distribution patterns. Groundwater recharged over Tertiary limestones show higher REY abundance and more significant Ce anomalies than those derived from the Cretaceous limestones. Weathering of alkali olivine basalts leads to REY patterns in groundwater depleted in the middle REE. The improved knowledge of the hydrological systems is thought to be useful for regional hydrogeological modeling and for designing rational water management schemes.

  15. Implications of diapir-derived detritus and gypsic paleosols in Lower Triassic strata near the Castle Valley salt wall, Paradox Basin, Utah

    2006-10-01

    Gypsum-bearing growth strata and sedimentary facies of the Moenkopi Formation on the crest and NE flank of the Castle Valley salt wall in the Paradox Basin record salt rise, evaporite exposure, and salt-withdrawal subsidence during the Early Triassic. Detrital gypsum and dolomite clasts derived from the middle Pennsylvanian Paradox Formation were deposited in strata within a few kilometers of the salt wall and indicate that salt rise rates roughly balanced sediment accumulation, resulting in long-term exposure of mobile evaporite. Deposition took place primarily in flood-basin or inland sabkha settings that alternated between shallow subaqueous and subaerial conditions in a hyperarid climate. Matrix-supported and clast-supported conglomerates with gypsum fragments represent debris-flow deposits and reworked debris-flow deposits, respectively, interbedded with flood-basin sandstone and siltstone during development of diapiric topography. Mudstone-rich flood-basin deposits with numerous stage I to III gypsic paleosols capped by eolian gypsum sand sheets accumulated during waning salt-withdrawal subsidence. Association of detrital gypsum, eolian gypsum, and gypsic paleosols suggests that the salt wall provided a common source for gypsum in the surrounding strata. This study documents a previously unrecognized salt weld with associated growth strata containing diapir-derived detritus and gypsic palesols that can be used to interpret halokinesis.

    2018-01-01

    An advanced research version of the Weather Research and Forecasting (WRF) Model is employed to simulate a wintertime inversion fog event in the Salt Lake Valley during the Mountain Terrain Atmospheric Modeling and Observations Program (MATERHORN) field campaign during January 2015. Simulation results are compared to observations obtained from the field program. The sensitivity of numerical simulations to available cloud microphysical (CM), planetary boundary layer (PBL), radiation, and land surface models (LSMs) is evaluated. The influence of differing visibility algorithms and initialization times on simulation results is also examined. Results indicate that the numerical simulations of the fog event are sensitive to the choice of CM, PBL, radiation, and LSM as well as the visibility algorithm and initialization time. Although the majority of experiments accurately captured the synoptic setup environment, errors were found in most experiments within the boundary layer, specifically a 3° warm bias in simulated surface temperatures compared to observations. Accurate representation of surface and boundary layer variables are vital in correctly predicting fog in the numerical model.

    The report briefly reviews the energy problem in the world, and then studies in detail the situation in Jordan. It covers the energy supply of crude oil, refined products, and non-commercial energy; energy demand; the current pattern of energy consumption of oil and electricity; a forecast of energy demand; the government subsidy of energy; new energy resources in Jordan (oil exploration and oil shale, tar sands, radioactive minerals, and renewable energy sources including geothermal, hydropower, solar, and wind). The report concludes that alternative energy sources must be developed by Jordan to meet the increased demand for energy and to reduce the dependence of Jordan on oil in the next decades.

  18. Measurements and Modeling of Turbulent Fluxes during Persistent Cold Air Pool Events in Salt Lake Valley, Utah

    Ivey, C. E.; Sun, X.; Holmes, H.

    2017-12-01

    Land surface processes are important in meteorology and climate research since they control the partitioning of surface energy and water exchange at the earth's surface. The surface layer is coupled to the planetary boundary layer (PBL) by surface fluxes, which serve as sinks or sources of energy, moisture, momentum, and atmospheric pollutants. Quantifying the surface heat and momentum fluxes at the land-atmosphere interface, especially for different surface land cover types, is important because they can further influence the atmospheric dynamics, vertical mixing, and transport processes that impact local, regional, and global climate. A cold air pool (CAP) forms when a topographic depression (i.e., valley) fills with cold air, where the air in the stagnant layer is colder than the air aloft. Insufficient surface heating, which is not able to sufficiently erode the temperature inversion that forms during the nighttime stable boundary layer, can lead to the formation of persistent CAPs during wintertime. These persistent CAPs can last for days, or even weeks, and are associated with increased air pollution concentrations. Thus, realistic simulations of the land-atmosphere exchange are meaningful to achieve improved predictions of the accumulation, transport, and dispersion of air pollution concentrations. The focus of this presentation is on observations and modeling results using turbulence data collected in Salt Lake Valley, Utah during the 2010-2011 wintertime Persistent Cold Air Pool Study (PCAPS). Turbulent fluxes and the surface energy balance over seven land use types are quantified. The urban site has an energy balance ratio (EBR) larger than one (1.276). Negative Bowen ratio (-0.070) is found at the cropland site. In addition to turbulence observations, half-hourly WRF simulated net radiation, latent heat, sensible heat, ground heat fluxes during one persistent CAP event are evaluated using the PCAPS observations. The results show that sensible and latent

  1. Decadal-scale changes in dissolved-solids concentrations in groundwater used for public supply, Salt Lake Valley, Utah

    Science.gov (United States)

    Thiros, Susan A.; Spangler, Larry

    2010-01-01

    Basin-fill aquifers are a major source of good-quality water for public supply in many areas of the southwestern United States and have undergone increasing development as populations have grown over time. During 2005, the basin-fill aquifer in Salt Lake Valley, Utah, provided approximately 75,000 acre-feet, or about 29 percent of the total amount of water used by a population of 967,000. Groundwater in the unconsolidated basin-fill deposits that make up the aquifer occurs under unconfined and confined conditions. Water in the shallow unconfined part of the groundwater system is susceptible to near-surface contamination and generally is not used as a source of drinking water. Groundwater for public supply is withdrawn from the deeper unconfined and confined parts of the system, termed the principal aquifer, because yields generally are greater and water quality is better (including lower dissolved-solids concentrations) than in the shallower parts of the system. Much of the water in the principal aquifer is derived from recharge in the adjacent Wasatch Range (mountain-block recharge). In many areas, the principal aquifer is separated from the overlying shallow aquifer by confining layers of less permeable, fine-grained sediment that inhibit the downward movement of water and any potential contaminants from the surface. Nonetheless, under certain hydrologic conditions, human-related activities can increase dissolved-solids concentrations in the principal aquifer and result in groundwater becoming unsuitable for consumption without treatment or mixing with water having lower dissolved-solids concentrations. Dissolved-solids concentrations in areas of the principal aquifer used for public supply typically are less than 500 milligrams per liter (mg/L), the U.S. Environmental Protection Agency (EPA) secondary (nonenforceable) drinking-water standard. However, substantial increases in dissolved-solids concentrations in the principal aquifer have been documented in some

    The potential of geothermal energy utilization in Jordan was discussed. The report gave a summary of the location of geothermal anomalies in Jordan, and of ongoing projects that utilize geothermal energy for greenhouse heating, fish farming, refrigeration by absorption, and water desalination of deep aquifers. The problems facing the utilization of geothermal energy in Jordan were identified to be financial (i.e. insufficient allocation of local funding, and difficulty in getting foreign financing), and inadequate expertise in the field of geothermal energy applications. The report gave a historical account of geothermal energy utilization activities in Jordan, including cooperation activities with international organizations and foreign countries. A total of 19 reports already prepared in the areas of geochemical and hydrological studies were identified. The report concluded that the utilization of geothermal energy offers some interesting economic possibilities. (A.M.H.). 4 refs. 1 map

    High pollution events are common in many locations in the U.S.A. and around the world. They can last several days or up to weeks and they negatively affect human health, deteriorate visibility, and increase premature mortality. The main causes for high pollution events are related to meteorology and sources. They often happen in the winter, when high emissions, stagnation and reduced mixing, due to a shallow boundary layer, cause high concentrations of pollutants to accumulate. In the last decades, the air quality in the U.S. has seen an overall improvement, due to the reductions in particulate and gaseous pollutants. However, some areas remain critical. The Great Salt Lake Basin and its adjacent valleys are currently areas where high pollution events are a serious environmental problem involving more than 2.4 million people. We will present the results of the Utah Wintertime Fine Particulate Study (UWFPS) that took place in winter 2017. During UWFPS, we carried out airborne measurements of aerosol chemical composition and precursor vapor concentrations over the Great Salt Lake Basin and its adjacent valleys. We will give insights into how and under which conditions conversion of precursor vapors into aerosol particles takes place in the area. We will also present a comparison of our measurements with models that will provide an insight of the mechanisms that lead to the formation of secondary aerosol particles. With the results of our work, we aim to inform strategies for pollution control in the future.

    On 25 May 2014, a rain-on-snow–induced rock avalanche occurred in the West Salt Creek valley on the northern flank of Grand Mesa in western Colorado (United States). The avalanche mobilized from a preexisting rock slide in the Green River Formation and traveled 4.6 km down the confined valley, killing three people. The avalanche was rare for the contiguous United States because of its large size (54.5 Mm3) and high mobility (height/length = 0.14). To understand the avalanche failure sequence, mechanisms, and mobility, we conducted a forensic analysis using large-scale (1:1000) structural mapping and seismic data. We used high-resolution, unmanned aircraft system imagery as a base for field mapping, and analyzed seismic data from 22 broadband stations (distances earth and tracked these forces using curves in the avalanche path. Our results revealed that the rock avalanche was a cascade of landslide events, rather than a single massive failure. The sequence began with an early morning landslide/debris flow that started ∼10 h before the main avalanche. The main avalanche lasted ∼3.5 min and traveled at average velocities ranging from 15 to 36 m/s. For at least two hours after the avalanche ceased movement, a central, hummock-rich core continued to move slowly. Since 25 May 2014, numerous shallow landslides, rock slides, and rock falls have created new structures and modified avalanche topography. Mobility of the main avalanche and central core was likely enhanced by valley floor material that liquefied from undrained loading by the overriding avalanche. Although the base was likely at least partially liquefied, our mapping indicates that the overriding avalanche internally deformed predominantly by sliding along discrete shear surfaces in material that was nearly dry and had substantial frictional strength. These results indicate that the West Salt Creek avalanche, and probably other long-traveled avalanches, could be modeled as two layers: a thin, liquefied

    Full Text Available Salinity and trace mineral accumulation threaten the sustainability of crop production in many semi-arid parts of the world, including California’s western San Joaquin Valley (WSJV. We used data from a multi-year field-scale trial in Kings County and related container trials to simulate a forage-grazing system under saline conditions. The model uses rainfall and irrigation water amounts, irrigation water quality, soil, plant, and atmospheric variables to predict Bermuda grass (Cynodon dactylon (L. Pers. growth, quality, and use by cattle. Simulations based on field measurements and a related container study indicate that although soil chemical composition is affected by irrigation water quality, irrigation timing and frequency can be used to mitigate salt and trace mineral accumulation. Bermuda grass yields of up to 12 Mg dry matter (DM·ha−1 were observed at the field site and predicted by the model. Forage yield and quality supports un-supplemented cattle stocking rates of 1.0 to 1.2 animal units (AU·ha−1. However, a balance must be achieved between stocking rate, desired average daily gain, accumulation of salts in the soil profile, and potential pollution of ground water from drainage and leaching. Using available weather data, crop-specific parameter values and field scale measurements of soil salinity and nitrogen levels, the model can be used by farmers growing forages on saline soils elsewhere, to sustain forage and livestock production under similarly marginal conditions.

    1. A study was conducted to investigate the effectiveness of high dietary copper concentrations obtained from tribasic copper chloride (TBCC, 58% copper) and copper sulphate pentahydrate (CuSO4, 25% copper) in replacing antibiotic growth promoters (AGP) in duck diets. 2. A total of 960 one-day-old Cherry Valley meat-strain ducks were divided into 3 treatment groups, with 8 replicates per treatment, in a 6-week feeding trial. The ducks were fed a basal diet supplemented with AGP (40 mg zinc bacitracin/kg and 40 mg garlicin/kg of diet) or 150 mg of Cu/kg of diet, given as either CuSO4 or TBCC. 3. The body weight, average daily gain, average daily feed intake and mortality of ducks were not affected by the dietary treatments. However, the feed/gain ratio of ducks that were fed TBCC diets was significantly lower than those of ducks that were fed CuSO4 diets and were similar to those in the AGP group. 4. TBCC increased the Cu content in the liver tissue of ducks compared with the content in those that were fed the diet supplemented with AGP. TBCC also increased the Fe and Zn content in breast muscles compared with that in ducks that were fed the diet supplemented with CuSO4. 5. The activities of superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) were significantly higher in the serum of ducks that received the diet supplemented with TBCC than AGP or CuSO4. TBCC treatment decreased the malondialdehyde (MDA) content in serum of ducks compared with groups supplemented with CuSO4. 6. No significant difference was observed in liver or muscle fat content among the different dietary treatment groups. The serum low-density lipoprotein cholesterol concentration was lower in ducks fed AGP diets than those fed CuSO4 diets. 7. It was concluded that the replacement of AGP with 150 mg of Cu/kg of feed from TBCC improved the feed efficiency, trace mineral deposition and antioxidant status more than when the source of copper was CuSO4.

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

    Full Text Available The aim of this research paper is to examine the Jordanian banks using financial soundness indicators. This is to establish if Jordanian banks were affected because of the 2007/2008 financial crisis and determine the underlying reasons. The research paper was conducted on 25 banks in Jordan listed in the countries securities exchange. The research methodology used consisted of examining the banks financial records in order to derive four crucial Basel III ratio such as the capital adequacy ratio, the leverage ratio, the liquidity ratio and finally the Total Provisions (As % Of Non-Performing Loans %. The results revealed that out of the four hypotheses under examination Jordan Banks do not meet Basel financial Indicators for Capital Adequacy Ratio, Jordan Banks does not meet Basel financial Indicators for Liquidity Ratio , Jordan Banks do not meet Basel financial Indicators for Leverage Ratio and Jordan Banks do not meet Basel financial Indicators for Total Provisions (As % Of Non-Performing Loans ratio. Only one hypothesis was accepted based on the research outcomes. The rest of the hypothesis was rejected since the average trend line did not go below the Basel III required ratio level. The general outcome of the research revealed that Jordanian banks were not affected significantly by the financial crisis.

  20. Misrepresenting the Jordan River Basin

    Full Text Available This article advances a critique of the UN Economic and Social Commission for West Asia’s (ESCWA’s representation of the Jordan River Basin, as contained in its recently published Inventory of Shared Water Resources in Western Asia. We argue that ESCWA’s representation of the Jordan Basin is marked by serious technical errors and a systematic bias in favour of one riparian, Israel, and against the Jordan River’s four Arab riparians. We demonstrate this in relation to ESCWA’s account of the political geography of the Jordan River Basin, which foregrounds Israel and its perspectives and narratives; in relation to hydrology, where Israel’s contribution to the basin is overstated, whilst that of Arab riparians is understated; and in relation to development and abstraction, where Israel’s transformation and use of the basin are underplayed, while Arab impacts are exaggerated. Taken together, this bundle of misrepresentations conveys the impression that it is Israel which is the main contributor to the Jordan River Basin, Arab riparians its chief exploiters. This impression is, we argue, not just false but also surprising, given that the Inventory is in the name of an organisation of Arab states. The evidence discussed here provides a striking illustration of how hegemonic hydro-political narratives are reproduced, including by actors other than basin hegemons themselves.

The higher K/Na values in fluid inclusions from barite suggest that the brines interacted with K-rich rocks in the basement or siliciclastic sediments in the basin. Carbonate gangue minerals (ankerite and calcite) have δ13C and δ18O values that are close to the carbonate host rock and indicate fluid equilibrium between carbonate host rocks and hydrothermal brines. The δ34S values for sphalerite and galena fall within a narrow range (1 to 10 ‰) with a bulk value of 7.5 ‰, indicating a homogeneous source of sulfur. The δ34S values of barite are also relatively homogeneous (22 ‰), with 6 ‰ higher than the δ34S of local and regional Triassic evaporites (15 ‰). The latter are believed to be the source of sulfate. Temperature of deposition together with sulfur isotope data indicate that the reduced sulfur in sulfides was derived through thermochemical sulfate reduction of Triassic sulfate via hydrocarbons produced probably from Late Cretaceous source rocks. The 87Sr/86Sr ratio in the Bou Jaber barite (0.709821 to 0.711408) together with the lead isotope values of Bou Jaber galena (206Pb/204Pb = 18.699 to 18.737; 207Pb/204Pb = 15.635 to 15.708 and 208Pb/204Pb = 38.321 to 38.947) show that metals were extracted from homogeneous crustal source(s). The tectonic setting of the Bou Jaber ore deposit, the carbonate nature of the host rocks, the epigenetic style of the mineralization and the mineral associations, together with sulfur and oxygen isotope data and fluid inclusion data show that the Bou Jaber lead-zinc mineralization has the major characteristics of a salt diapir-related Mississippi Valley-type (MVT) deposit with superimposed events of fluorite and of barite deposition.

  7. Strong Control of Salts on Near Surface Liquid Water Content in a High Polar Desert Indicated by Near Surface Resistivity Mapping with a Helicopter-Borne TEM Sensor, Lower Taylor Valley, Antarctica

    Closed depressions in the Lower Taylor Valley (McMurdo Dry Valleys, Antarctica) have near surface (top 5m) electrical resistivity that is lower by about an order of magnitude than the resistivity of nearby slopes and ridges (100s of ohm-m vs. 1000s). We interpret this spatial pattern as being due to long term concentration of salts carried by liquid water and/or deliquescent vapor fronts. High concentration of salts in the top decimeters to meters beneath the surface may prolong the existence and abundance of liquid water in this otherwise very cold and dry high polar desert. Due to its connections with life and chemical transport, liquid water is a much studied feature in the McMurdo Dry Valleys. This setting can be used as an analogue for similar features on the surface of Mars, where liquid water tracks have been observed and are believed to be controlled by eutectic brines. Our study demonstrates the utility of mapping at a regional scale via helicopter-borne Transient EM. Airborne EM covers more ground and can measure deeper than surface-based measurements, at the expense of resolution. This allows creating valley-scale datasets which could not feasibly be collected on the ground. Our remote measurements complement physical samples that indicate that soluble salts concentrate in certain areas of surface soil where water moves ions and is later removed by evaporation or sublimation. In areas where we measured low resistivity, the integrated liquid water fraction in the top 5m may be a few to several percent by volume, equivalent to a few or several dozens of cm of water layer thickness. This estimate assumes that the interstitial waters have very low resistivity, comparable to seawater or hypersaline brines at freezing (0.2-0.35 ohm-m). If soil water was considerably fresher than this, liquid water content would have to reach dozens of percent throughout the top 5m for bulk resistivities to drop to 100s of ohm-m. We consider the latter case to be unlikely as

    The purpose of the U.S. Geological Survey's (USGS) National Oil and Gas Assessment is to develop geologically based hypotheses regarding the potential for additions to oil and gas reserves in priority areas of the United States. The USGS recently completed an assessment of undiscovered oil and gas potential of the Cotton Valley Group and Travis Peak and Hosston Formations in the East Texas Basin and Louisiana-Mississippi Salt Basins Provinces in the Gulf Coast Region (USGS Provinces 5048 and 5049). The Cotton Valley Group and Travis Peak and Hosston Formations are important because of their potential for natural gas resources. This assessment is based on geologic principles and uses the total petroleum system concept. The geologic elements of a total petroleum system include hydrocarbon source rocks (source rock maturation, hydrocarbon generation and migration), reservoir rocks (sequence stratigraphy and petrophysical properties), and hydrocarbon traps (trap formation and timing). The USGS used this geologic framework to define one total petroleum system and eight assessment units. Seven assessment units were quantitatively assessed for undiscovered oil and gas resources.

    Differences in the distribution of Na/Cl, Br/Cl and Mg/Ca equivalent values suggest a morphotectonic barrier at Marma Feiyad dividing the Tertiary Inland Sea into two basins covering the region of the Jordan Valley, Middle East. Depending on the Tethys sea level, three phases of evaporation are distinguishable that are related to three sections of the drilling log of Zemah 1. In phase 1 and 3 only the northern basin was flooded. During phase 2 both basins were inundated, but halite mainly precipitated in the southern one. The halite deposition in one or the other basin by evaporation is estimated by applying a two-box model. The results are constrained by the average subduction rate of 700-875 m/Ma and characteristic Na/Cl values of 0.52 and 0.12 in the northern and southern basin, respectively. In different scenarios the sedimentation rates of halite and non-halite components are varied due to assumed halokinesis, reshuffling of salt and erosion of non-halite sediments. These simulations suggest that periods of 450-600 and 100-170 ka in the southern and northern basin were needed, until the Na/Cl values of 0.12 and 0.52 were, respectively, attained. The Inland Sea most probably existed for 2.2 ± 0.3 Ma between 8.5 and 6.3 Ma ago (Tortonian). It was terminated at the beginning of the Messinian crisis. In all simulations the drainage flux into the southern basin exceeded that into the northern basin, suggesting that the proto-Jordan River either did not exist at that time or did not discharge into the northern basin.

    2016-12-01

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

    Summary Criminal attacks by burns on women in Jordan are highlighted in this retrospective study carried out of all proved cases of criminal burns in female patients treated at the burn unit of the Royal Rehabilitation Center in Jordan between January 2005 and June 2012. Thirteen patients were included in our study, out of a total of 550 patients admitted, all in the age range of 16-45 yr. Of these 13 women, six were burned by acid throwing, five by hot water, and two by direct flames from fuel thrown over them. Burn percentage ranged from 15 to 75% of the total body surface area, with involvement in most cases of the face and upper trunk. The mean hospital stay was 33 days and the mortality rate was 3/13, i.e. 23%. Violence against women exists in Jordanian society, yet burning assaults are rare. Of these, burning by throwing acid is the most common and most disfiguring act, with a higher mortality rate in domestic environments. PMID:23766757

    It is a well known fact that Jordan has neither crude petroleum for usage nor crude petroleum reserves. Also, Jordan is of great needs for res (Renewable Energy Systems) applications since it depends totally in generation of its required energy on imported oil. This makes Jordan depends on other countries to supply it with oil, which in turn, depends on the world-market prices and availability of oil. This puts Jordan in real energy of RES applications simply and safely. official establishments, research centers, institutes and universities are trying to make the way as smooth as possible to reach this goal. One of these research centers is the REB at the University of Jordan established in the year 2000, to work in cooperation with KADDB. It was seen that the application of RES is in permanent increasing in Jordan through the last 10 years.(Author)

    A geographic information system (GIS) focusing on the Upper Jurassic-Lower Cretaceous Cotton Valley Group and the Lower Cretaceous Travis Peak and Hosston Formations in the northern Gulf Coast region was developed as a visual-analysis tool for the U.S. Geological Survey's 2002 assessment of undiscovered, technically recoverable oil and natural gas resources in the East Texas Basin and Louisiana-Mississippi Salt Basins Provinces. The Central Energy Resources Team of the U.S. Geological Survey has also developed an Internet Map Service to deliver the GIS data to the public. This mapping tool utilizes information from a database about the oil and natural gas endowment of the United States-including physical locations of geologic and geographic data-and converts the data into visual layers. Portrayal and analysis of geologic features on an interactive map provide an excellent tool for understanding domestic oil and gas resources for strategic planning, formulating economic and energy policies, evaluating lands under the purview of the Federal Government, and developing sound environmental policies. Assessment results can be viewed and analyzed or downloaded from the internet web site, http://energy.cr.usgs.gov/oilgas/noga/ .

    2014-01-01

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

  5. The Thermal Waters of Jordan

    Sass, I.; Schäffer, R.

    2012-04-01

    In a recent field campaign all known natural hot spring areas of Jordan were investigated. Their hydrochemical properties including some fundamental isotopes were measured. Jordan's thermal springs can be classified into four thermal provinces (Nahr Al-Urdun, Hammamat Ma'in, Zara and Wadi Araba province), with similar hydrochemical and geologicalsettings. Thermal springs of Hammamat Ma'in and Zara province are situated on prominent faults. Reservoir temperature estimation with the Mg-corrected Na-K-Ca geothermometer indicates temperatures between 61 °C and 82 °C. Even taking into account the increased geothermal gradient at Dead Sea's east coast, the water's origin has to be considered mainly in deeper formations. Carbon dioxide, emitted by tertiary basalts situated close to the springs, may be responsible for gas lift. Mineralisation and δ18O-values indicate, that the spring water's origin is mostly fossil, i.e. not part of the global water cycle. It is shown, that ground water mining led to a shift within δ18O-ratio during the last 30 years due to a reduction of shallow water portion in addition to a dislocation of the catchment area. Ground water mining will impact the thermal spring productivity and quality anyway in the future. Present-day precipitation rates and catchment areas in Dead Sea region are by far not sufficient to explain relative high discharge. For the Hammamat Ma'in Province is documented, that discharge and maximal spring water temperatures are constant during the last 50 years, showing marginal seasonal oscillation and negligible influence by short-term climatic changes. The water characteristics of Hammamat Ma'in and Zara province are related. However, Zara waters feature systematically less ion concentration and lower temperatures due to a stronger influence of vadose water. The springs of Nahr Al-Urdun province are recharged mainly by shallow groundwater. Thus temperature and mineralisation is lower than at the springs at the Dead Sea

    Generating long term records of fossil fuel emissions of urban environments is complicated by the fact that direct observations of emissions and urban atmospheric CO2 concentrations were only collected in the recent past. Radiocarbon (14C) in tree rings from urban trees can provide archives of fossil fuel emissions that may track population growth over time, as higher population density is typically correlated with increased vehicular traffic and associated CO2 emissions, which are radiocarbon dead. We present radiocarbon measurements (n=125) from five roadside green ash trees (Fraxinus pennsylvanica) located in three cities of northern Utah - Salt Lake City (urban, 2016 population: 193,744), Logan City (agricultural, 2016 population: 49,110) and Heber (rural, 2016 population: 14,969). Urban trees were cored in four cardinal directions and ring widths were measured and counted to establish a chronology. One ring from every third year in a single core from each tree was removed and holocellulose was extracted from bulk wood of individual rings for 14C analysis. Fraction CO2 from fossil fuel burning (CO2-ff) was calculated using a simple mass-balance calculation from measured 14C values and remote background atmospheric 14CO2 values for NH Zone 2. The data from all three cities indicate a general trend of increasing CO2-ff uptake by the trees from 1980s to present, as expected with increased population growth and vehicular traffic. However, records in all three cities show unique elevated CO2-ff prior to the 1980s, assuming similar climate patterns through time, diverging from historic population size. We employed atmospheric simulations from the STILT (Stochastic Time-Inverted Lagrangian Transport) models for each of these trees to create footprints to determine source areas for CO2. These footprints reveal that atmospheric sampling areas can be large for certain trees, and other sources of 14C dead carbon, such as coal and natural gas from industrial emissions

    We investigate inflation models in Jordan frame supergravity, in which an inflaton non-minimally couples to the scalar curvature. By imposing the condition that an inflaton would have the canonical kinetic term in the Jordan frame, we construct inflation models with asymptotically flat potential through pole inflation technique and discuss their relation to the models based on Einstein frame supergravity. We also show that the model proposed by Ferrara et al. has special position and the relation between the Kaehler potential and the frame function is uniquely determined by requiring that scalars take the canonical kinetic terms in the Jordan frame and that a frame function consists only of a holomorphic term (and its anti-holomorphic counterpart) for symmetry breaking terms. Our case corresponds to relaxing the latter condition.

    Full Text Available Objective: To estimate the burden of fungal infections in Jordan for the first time. Material and Methods: Population data was from UN 2011 statistics and TB cases from WHO in 2012. Fewer than 100 patients with HIV were recorded in Jordan in 2013. Approximately 100 renal transplants and eight liver transplants are performed annually. There were 12,233 major surgical procedures in Jordan in 2013, of which 5.3% were major abdominal surgeries; candidemia was estimated in 5% of the population based on other countries, with 33% occurring in the ICU. Candida peritonitis/intra-abdominal candidiasis was estimated to affect 50% of the number of ICU candidemia cases. No adult asthma rates have been recorded for Jordan, so the rate from the Holy Land (8.54% clinical asthma from To et al. has been used. There are an estimated 49,607 chronic obstructive pulmonary disease (COPD patients in Jordan, with 64% symptomatic, 25% Gold stage 3% or 4%, and 7% (3472 are assumed to be admitted to hospital each year. No cystic fibrosis cases have been recorded. Literature searches on fungal infections revealed few data and no prevalence data on fungal keratitis or tinea capitis, even though tinea capitis comprised 34% of patients with dermatophytoses in Jordan. Results: Jordan has 6.3 million inhabitants (65% adults, 6% are >60 years old. The current burden of serious fungal infections in Jordan was estimated to affect ~119,000 patients (1.9%, not including any cutaneous fungal infections. Candidemia was estimated at 316 cases and invasive aspergillosis in leukemia, transplant, and COPD patients at 84 cases. Chronic pulmonary aspergillosis prevalence was estimated to affect 36 post-TB patients, and 175 in total. Allergic bronchopulmonary aspergillosis (ABPA and severe asthma with fungal sensitization (SAFS prevalence in adults with asthma were estimated at 8900 and 11,748 patients. Recurrent vulvovaginal candidiasis was estimated to affect 97,804 patients, using a 6

    2008-06-01

    Until now, only a few systematic surveys of entomopathogenic nematodes (EPN) have been conducted in Middle Eastern countries. Many of the recovered EPN species in this region have shown to own distinctive qualities that enable their survival in unique environments, such as high temperatures and low moisture levels tolerance. These new species and strains, with unique environmental tolerances, are more suitable for their consideration in pest management programs in xerophytic regions. With this background in mind, we recently conducted a survey of EPN in Jordan. This study records for the first time the diversity and distribution of these nematodes and their bacterial symbionts in this country. Jordan's three geographic regions: (1) the highlands, (2) Jordan valley and (3) the desert region were sampled. Within each region, natural habitats and agricultural regions characteristic to each region were considered for sampling purposes. Four EPN species including three Steinernema and one Heterorhabditis were recovered. Nematodes were identified using a combination of molecular markers and classic morphological diagnostic tools. Bacterial symbionts were identified by analysis of 16S rRNA sequences. Abiotic characteristics such as soil type, soil pH, and elevation were also recorded. We herein report the diversity of EPN species in Jordan and discuss their potential in Biocontrol and IPM programs for this country.

    2017-08-10

    This study examined the recent level, trends and determinants of consanguineous marriage in Jordan using time-series data from the Jordan Population and Family Health Surveys (JPFHSs). According to the 2012 JPFHS, 35% of all marriages were consanguineous in Jordan in 2012. There has been a declining trend in consanguinity in the country, with the rate decreasing from a level of 57% in 1990. Most consanguineous marriage in 2012 were first cousin marriages, constituting 23% of all marriages and 66% of all consanguineous marriages. The data show that women with a lower age at marriage, older marriage cohort, larger family size, less than secondary level of education, rural place of residence, no employment, no exposure to mass media, a monogamous marriage, a husband with less than higher level of education and lower economic status, and those from the Badia region, were more likely to have a consanguineous marriage. Increasing age at marriage, level of education, urbanization and knowledge about the health consequences of consanguinity, and the ongoing socioeconomic and demographic transition in the country, will be the driving forces for further decline in consanguinity in Jordan.

    1977-08-01

    Jordanian geology is dominated by the Great Rift Valley System. Most of the country is covered by Cretaceous and Eocene sediments, largely sandstones and limestones. These include phosphorates and bituminous limestones in the Upper Cretaceous, South of the Dead Sea, Mesozoic and Paleozoic rocks overlie exposed granitic Pre Cambrian basement rocks carrying many minor intrusives . Phosphates provide the main mineral export of Jordan. The Natural Resources Authority (Geological Survey and Bureau of Mines) initiated a survey in 1972 of the distribution of uranium on the phosphorite horizon. In 1974 the Survey calculated that the uranium content of the phosphate areas surveyed up to that time was 5 million metric tonnes U 3 O 8 . The average U 3 O 8 content is approximately 0.02% U 3 O 8 . The exploitation of such resources would be as a byproduct of the phosphate industry and dependent on the rate of phosphate production and the capacity of triple super-phosphate plants, none of which exist at the present time. In the southern area in Paleozoic and Pre Cambrian areas there are some hopes of conventional type deposits being found but the potential appears to be small. (author)

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

    2013-04-01

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

    2007-08-01

    The purpose of the study was to examine patients' preferences for nurses' gender in Jordan. The public, private and university hospitals are represented by selecting one major hospital from each health sector. The sample size was 919 participants. Data were collected by a questionnaire through standardized individual interviews with patients. The findings of the study indicate that gender preferences are stronger among female patients than among male patients. Furthermore, two-thirds of female patients preferred female nurses, whereas only 3.4% preferred male nurses to care for them. In contrast, one-third of male patients' preferred male nurses, and only 10% preferred female nurses. The authors recommend that the high percentage of male nursing students need to be reconsidered by health policy-makers in Jordan.

    A precise relation between the structures of Lie and Jordan algebras by presenting a method of constructing one type of algebra from the other is established. The method differs in some aspects of the Tits construction and Jordan pairs. The examples of the Lie algebras associated to simple Jordan algebras M m (n ) and Clifford algebras are discussed in detail. This approach will shed light on the role of the realizations of Jordan algebras through some types of Fermi fields used in the construction of Kac-Moodey and Virasoro algebras as well as its relevance in the study of some aspects of conformal fields theories.

    Hernandez, E.; Mondragon, A.; Jauregui, A.

    2002-01-01

    An accidental degeneracy of resonances gives rise to a double pole in the scattering matrix, a double zero in the Jost function and a Jordan chain of length two of generalized Gamow-Jordan eigenfunctions of the radial Schrodinger equation. The generalized Gamow-Jordan eigenfunctions are basis elements of an expansion in bound and resonant energy eigenfunctions plus a continuum of scattering wave functions ol complex wave number. In this bi orthonormal basis, any operator f (H r (l) which is a regular function of the Hamiltonian is represented by a complex matrix which is diagonal except for a Jordan block of rank two. The occurrence of a double pole in the Green's function, as well as the non-exponential time evolution of the Gamow-Jordan generalized eigenfunctions are associated to the Jordan block in the complex energy representation.

  7. Jordan First”: Tribalism, Nationalism and Legitimacy of Power in Jordan

    2010-06-01

    Full Text Available Abstract: The significance of tribal identity in Jordan can be seen in the special relationship of traditional institutions with the state, which shows both the fluctuation in the concept of tribalism and how tribalism can be better understood by viewing it through the perspective of “Jordanian nationalism”. This relationship has created confusion on the local and national levels about how the state system should work through its institutions. Furthermore, the process of democratization is only a façade; Jordan is supposedly a constitutional monarchy, but in fact the king holds absolute power. The parliament’s autonomy has been minimal, in other words, the parliament is a symbol of democracy but is widely perceived as non-representative. This paper examines the regime security strategy “Jordan First” and the particularity of Jordanian identity through its relationship to the concept of a Jordanian national consensus.

  8. Determination of hydrologic properties needed to calculate average linear velocity and travel time of ground water in the principal aquifer underlying the southeastern part of Salt Lake Valley, Utah

    1994-01-01

    A 48-square-mile area in the southeastern part of the Salt Lake Valley, Utah, was studied to determine if generalized information obtained from geologic maps, water-level maps, and drillers' logs could be used to estimate hydraulic conduc- tivity, porosity, and slope of the potentiometric surface: the three properties needed to calculate average linear velocity of ground water. Estimated values of these properties could be used by water- management and regulatory agencies to compute values of average linear velocity, which could be further used to estimate travel time of ground water along selected flow lines, and thus to determine wellhead protection areas around public- supply wells. The methods used to estimate the three properties are based on assumptions about the drillers' descriptions, the depositional history of the sediments, and the boundary con- ditions of the hydrologic system. These assump- tions were based on geologic and hydrologic infor- mation determined from previous investigations. The reliability of the estimated values for hydro- logic properties and average linear velocity depends on the accuracy of these assumptions. Hydraulic conductivity of the principal aquifer was estimated by calculating the thickness- weighted average of values assigned to different drillers' descriptions of material penetrated during the construction of 98 wells. Using these 98 control points, the study area was divided into zones representing approximate hydraulic- conductivity values of 20, 60, 100, 140, 180, 220, and 250 feet per day. This range of values is about the same range of values used in developing a ground-water flow model of the principal aquifer in the early 1980s. Porosity of the principal aquifer was estimated by compiling the range of porosity values determined or estimated during previous investigations of basin-fill sediments, and then using five different values ranging from 15 to 35 percent to delineate zones in the study area that were assumed to

    2009-01-01

    The concentrations of trace metals (Fe, Mn, Ni, Zn, Co, Cr, Cu and Pb) were investigated in the Dead Sea black mud and river sediments in the northern basin of the Dead Sea region, Jordan. The pH of the mud was slightly above 8 while it was around 6 for the seawater. All analyzed heavy metal content in the black mud, except Pb, was less than their contents in other types of mud. Tlis might be due to the effect of the mildly acideic pH of seawater, which would enhance the metal solubility or incorporation within salt mineral structure, rather than precipitation. The sequential extraction results showed that Ni and Co transferred into the carbonate fraction, Mn is found mostly as manganese-iron oxide, and the residual phase contained Cr, Cu, Fe,and Pb. This study illustrated that the black mud had low heavy metal contents, thus indicating low toxicity. additionally, it shows insignificance effect of the mixing of freshwater with seawater on the heavy metal contents in the black mud.

Carbon monoxide, nitrogen dioxide, sulphur dioxide and total suspended particle matter (TSP) were measured at the Downtown station. At the other sites only TSP was measured. A short-term monitoring program carried out with a mobile monitoring unit showed relatively low levels of sulfur dioxide, carbon monoxide and nitrogen dioxide at the RSS, Naser and Marka sites as compared to the Downtown site. Continuous analyzers purchased from Environment SA, France, were used to measure sulfur dioxide, carbon monoxide and nitrogen dioxide; Sierra-Anderson high volume samplers equipped with glass fiber filters were used to collect total suspended particulates samples. Gaseous pollutants were continuously measured at the Downtown site and TSP samplers were operated on a three day schedule at all sites. Sampling began in July 1986 and continues to the present

    This study was performed prospectively to the dizzy patients in the Neurotology Outpatient Clinic at Jordan University Hospital, Amman, Jordan during the period 1993-2000 and to discuss the prevalence and and etiology of dizziness. Data were collected from 108 patients (52 male and 56 female) with a mean age of 45.6-years. diagnosis was made on the basis of history, physical, otolarygological and neurological examination and confirmed by relevant investigation including laboratory, radiological and audio vestibular tests. Secure diagnosis was made in 98% of patients (14% had one cause alone and 84% had multiple causes). Cardivascular disorders accounted for 31.5% of primary and 49% of secondary causes, perpheral vestibular disorders, 25% of primary and 3% of secondary causes, central vestibular disorders 17% of primary and 9% of secondary causes, metabolic endocrine 13% of primary and 38% of secondary causes and psychogenic 4.6% of primary and 6.5% of secondary causes.Our findings demonstrate that vertigo is most common subtype of dizziness (50%). Multiple causes are more prevalent in older age and single cause is more prevalent in younger age. Cardiovascular was the most common cause of dizziness followed by vestibular disorders, metabolic and cervical osteoarthritis. Vestibular disorders are primary causes and non vestibular are predominantly secondary causes of dizziness. Hyperlipidemia, diabetes and cervical causes are major secondary contributionsto dizziness. We recommend a a multi disciplinary setting and application of a comprehensive diagnostic and treatment approach without unnecessary protracted investigative schemeand installment of rehabilitatioon facilities.

    To assess the pituitary findings as demonstrated on MRI and to compare the results with the data published in the literature. One thousand, one hundred and thirty-eight pituitary MRIs with and without intravenous contrast media (gadolinium) were performed over 6 years from 2001 to 2007 in the Department of Diagnostic Radiology, Jordan University Hospital, Amman, Jordan. The patients were referred from various departments and were evaluated for pituitary, other sellar, and juxtasellar abnormalities. The results were compared with those in the published literature. Four hundred and eight-three normal scans were excluded from the study. The remaining 655 were abnormal, pituitary adenoma was detected in 327 (49.9%), microadenoma was present in 213 (32.5%), and macroadenoma in 114 (17.4%). Partial empty sella was seen in 157 (24%), diffuse pituitary gland enlargement in 98 (14.9%), ectopic pituitary posterior lobe in 13 (2%), and other findings in 31 (4.7%). The incidence of pituitary adenoma was equal in both genders; however, microadenoma was more common, affected a younger age group, and was predominately seen in females. The other parameters showed agreement with the published literature. (author)

  19. Bumper Stickers in Jordan: A Structural Analysis

    Full Text Available This study has set out to determine the structural patterns of bumper stickers in Jordan. This study is significant since it is the first one to approach bumper stickers structurally. The study has investigated 227 stickers, which can be considered the corpus of stickers in Jordan. The study has found that around 90% of the stickers are sentences, most of which are simple sentences expressed in the present tense. This combination of the three elements i.e. sentence, declarative and simple is what facilitated the job of drivers to write their opinions, attitudes, beliefs, etc. and is what made it possible for the others i.e. drivers and pedestrians to understand the stickers. The study has also found that imperative and negative imperatives are quite common since the stickers are not addressed to the writer/driver rather to the others so as to inform them about his state, his miserable condition, his opinions, his loyalties, and his vehicle. The stickers are addressed to others to demand certain behaviors from them such as driving wisely, not challenging the sticker writer, respecting him if he is driving a truck or a lorry, etc.

  20. Jordan cells of periodic loop models

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

  1. Microscopic Identification of Prokaryotes in Modern and Ancient Halite, Saline Valley and Death Valley, California

    Primary fluid inclusions in halite crystallized in Saline Valley, California, in 1980, 2004-2005, and 2007, contain rod- and coccoid-shaped microparticles the same size and morphology as archaea and bacteria living in modern brines. Primary fluid inclusions from a well-dated (0-100,000 years), 90 m long salt core from Badwater Basin, Death Valley, California, also contain microparticles, here interpreted as halophilic and halotolerant prokaryotes. Prokaryotes are distinguished from crystals on the basis of morphology, optical properties (birefringence), and uniformity of size. Electron micrographs of microparticles from filtered modern brine (Saline Valley), dissolved modern halite crystals (Saline Valley), and dissolved ancient halite crystals (Death Valley) support in situ microscopic observations that prokaryotes are present in fluid inclusions in ancient halite. In the Death Valley salt core, prokaryotes in fluid inclusions occur almost exclusively in halite precipitated in perennial saline lakes 10,000 to 35,000 years ago. This suggests that trapping and preservation of prokaryotes in fluid inclusions is influenced by the surface environment in which the halite originally precipitated. In all cases, prokaryotes in fluid inclusions in halite from the Death Valley salt core are miniaturized (<1 μm diameter cocci, <2.5 μm long, very rare rod shapes), which supports interpretations that the prokaryotes are indigenous to the halite and starvation survival may be the normal response of some prokaryotes to entrapment in fluid inclusions for millennia. These results reinforce the view that fluid inclusions in halite and possibly other evaporites are important repositories of microbial life and should be carefully examined in the search for ancient microorganisms on Earth, Mars, and elsewhere in the Solar System.

    We examine the bubble nucleation rate in a first-order phase transition taking place in a background Jordan-Brans-Dicke cosmology. We compute the leading order terms in the nucleation rate when the Jordan-Brans-Dicke field is large (i.e., late times) by means of a Weyl rescaling of the fields in the theory. We find that despite the fact that the Jordan-Brans-Dicke field (hence the effective gravitational constant) has a time dependence in the false vacuum, at late times the nucleation rate is time independent. 21 refs

    Accelerator mass spectrometry results of 36 Cl for the Jordan River/Dead Sea system show that the amount of chloride leached from rocks ranges from approx. 70% in source springs to >90% in water bodies downstream. Furthermore, the amount of water left after evaporation decreases from approx. 50% in the source springs to 20% in the intermediate Lake Kinneret. In the terminal Dead Sea, 99% of the stable chloride originates from ancient rocks and evaporite formations while approx. 80% of its 36 Cl content is of meteoric origin. Using 36 Cl measurements, the accumulation time of the Dead Sea salt is estimated to be 19,000-25,000 yr. (author)

    2003-10-01

    Using the Jordan algebras method, specially the properties of Peirce decomposition and the Frobenius transformation, we compute the coefficients of the zeta functional equation, in the case of Jordan algebras of Type II. As particular cases of our result, we can cite the case of V M (n, R) studied by Gelbart and Godement-Jacquet, and the case of V Herm(3, O s ) studied by Muro. Let us also mention, that recently, Bopp and Rubenthaler have obtained a more general result on the zeta functional equation by using methods based on the algebraic properties of regular graded algebras which are in one to one correspondence with simple Jordan algebras. The method used in this paper is a direct application of specific properties of Jordan algebras of Type H. (author)

    Full Text Available Fig mosaic (FM is one of the most important diseases of figs in Jordan. A nationwide survey was conducted to determine the incidence and severity of this disease in trees and in seedlings propagated by cuttings in orchards and nurseries in 13 provinces and cities all over the country. Cultivars surveyed included Khdari, Mwazi, Zraki, Khartamani, Dafoori, Turki, Hamari, Esaili, Ajlouni, in addition to an Italian and a French cultivar. Disease severity varied from moderately severe to extremely severe with leaf malformation and fruit drop FM was found in all provinces. Incidence of FM, averaged over trees of all cultivars and all age categories, was 95.3%. Fig trees 3 years and older had the highest disease incidence, ranging from 93.3% to 100% in the different orchards. The Esaili cultivar had the lowest incidence ranging between 50% and100%, with an average of 76.5%. The highest FM incidence was on Dafoori. Of the most common cultivars, Khdari was the most susceptible. Jerash province had the highest percentage (12.5% of fig seedlings and trees in the most severe disease category. The highest percentage (27.8% of healthy fig seedlings and trees was in Irbid province. This paper reports the incidence of FM in various local and imported fig cultivars of different ages, and relates the spread of the disease to the method of fig propagation practiced in Jordan. Suggested solutions for the problem, which include the introduction of disease and pest free fig seedlings derived from tissue culture and the establishment of new rules and regulations to prevent the spread of the disease are discussed.

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

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

    Artemisia judaica L. (Arabic name: Beithran), is a medicinal and aromatic plant growing in the valley bottoms of desert areas, particularly in the southern desert of Jordan nearest to the Jordan-Saudi Arabia borders and in Wadi Araba in the Southern Badia. In Jordan, A. judaica is widely used in traditional medicine being recommended by aboriginal Bedouins in the North Badia region of Jordan as calmative. Furthermore, it is used for the treatment of stomach ache, heart diseases, sexual weakness, diabetes, gastro-intestinal disorders and external wounding. Additionally, other folk medicines of the Arabic region commonly use this aromatic plant for the treatment of inflammatory-related diseases, for instance fungal infections, diabetes, atherosclerosis, cancer and arthritis. Considering the traditional medicinal uses and the lack of scientific studies addressing the cellular and molecular mechanisms behind A. judaica claimed activities, the present study was designed to validate some of the traditional uses ascribed to this species, specifically the antifungal and anti-inflammatory activities of A. judaica essential oil at doses devoid of cytotoxicity to mammalian cells. Chemical analysis of A. judaica essential oil isolated by hydrodistillation from aerial parts was carried out by gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS). The antifungal activity (minimal inhibitory concentrations and minimal lethal concentrations) was evaluated against yeasts, dermatophyte and Aspergillus strains. In order to deeply explore the mechanisms behind the anti-fungal effect of the essential oil, the germ tube inhibition assay and the biofilms formation assay were evaluated using Candida albicans. The assessment of cell viability was accomplished using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay in both hepatocytes and macrophages. Furthermore, the in vitro anti-inflammatory potential of A. judaica oil was evaluated by

    With 20-30% of all marriages occurring between first cousins, increasing attention in Jordan is now given to role of consanguinity in the occurrence of genetic diseases. The objective of this study is to define the specific categories of genetic disorders associated with consanguineous marriages. Etiological categories and consanguinity rates were studied among 623 families with genetic syndromes, congenital anomalies or mental retardation, or both, seen at the National Center for Diabetes, Endocrinology and Genetics for the period August 2002 to August 2006. Comparisons were made for first cousin marriage rates in the study group and that for the general population. First cousin marriages constituted 69%, 22% and 41.7% of marriages among families with autosomal recessive conditions (group 1), dominant, X-linked and chromosomal conditions (group 2) and sporadic undiagnosed conditions (group 3) respectively. The differences in the rates of the first cousin matings were highly significant when comparing known figures in the general population with group 1 and 3, but not significant with group 2. Two messages to the public and health care personnel regarding consanguinity can be derived from this study. The first message is that among genetic disorders, only autosomal recessive disorders are strongly associated with consanguinity. The second message is that approximately 30% of sporadic undiagnosed cases of mental retardation, congenital anomalies and dimorphism may have an autosomal recessive etiology with risks of recurrence in future pregnancies.

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

    In this study Jordan's energy options were evaluated and ranked with respect to several criteria clusters including financial, technical, environmental, ecological, social, and risk assessment. The Analytical Hierarchy Process; a multi-criteria decision-making analysis, was selected to evaluate the electricity generation options for Jordan. Energy options covered in the analysis include both conventional and renewable sources. Conventional sources evaluated include Oil and Natural Gas. Renewable sources covered wind, biomass, Photovoltaic and concentrated solar systems. The study also investigated generation from nuclear energy and direct combustion of oil shale as well as demand side savings from energy efficiency measures as a resource. Results indicate that to date; conventional fuels remain Jordan's most feasible options from a technical and financial perspective. Nonetheless diversification is essential to promoting energy security as well as environmental welfare. Results indicate that Jordan's best diversification options are nuclear, oil shale, biomass, and wind energy. - Highlights: • A Multi-Criteria Optimization Analysis technique was used to compare nine electricity generation options. • Options considered included Fossil Fuel sources, Nuclear Energy , Renewable Energy and Energy Efficiency. • Six criteria clusters were considered: financial, technical, environmental, ecological, social, and risk assessment. • Results outline potential policy implications for diversifying Jordan's energy mix. • Conventional fuels remain integral and Oil shale, Nuclear, Biomass and Wind offer the best diversification potential.Tag as highlight.

  6. Valley polarization in bismuth

    Science.gov (United States)

    Fauque, Benoit

    2013-03-01

    The electronic structure of certain crystal lattices can contain multiple degenerate valleys for their charge carriers to occupy. The principal challenge in the development of valleytronics is to lift the valley degeneracy of charge carriers in a controlled way. In bulk semi-metallic bismuth, the Fermi surface includes three cigar-shaped electron valleys lying almost perpendicular to the high symmetry axis known as the trigonal axis. The in-plane mass anisotropy of each valley exceeds 200 as a consequence of Dirac dispersion, which drastically reduces the effective mass along two out of the three orientations. According to our recent study of angle-dependent magnetoresistance in bismuth, a flow of Dirac electrons along the trigonal axis is extremely sensitive to the orientation of in-plane magnetic field. Thus, a rotatable magnetic field can be used as a valley valve to tune the contribution of each valley to the total conductivity. As a consequence of a unique combination of high mobility and extreme mass anisotropy in bismuth, the effect is visible even at room temperature in a magnetic field of 1 T. Thus, a modest magnetic field can be used as a valley valve in bismuth. The results of our recent investigation of angle-dependent magnetoresistance in other semi-metals and doped semiconductors suggest that a rotating magnetic field can behave as a valley valve in a multi-valley system with sizeable mass anisotropy.

    We attempted in this study, to estimate the prevalence of primarynocturnal enuresis (PNE) in children of Jordan and to examine factorsassociated with PNE. We sent questionnaires to 950 parents of children aged6-8 years, randomly selected from three primary schools in Jordan. Thequestionnaire was designed to evaluate the prevalence and factors associatedwith PNE. The response rate was 71.6%. The overall prevalence of PNE was23.8%. This prevalence declined with age from 48.9% at 7 years and 8.4% at 8years. Our findings indicate that the prevalence of PNE in Jordan is higherthan the reported from other Asian or European countries, while theassociated factors are similar. (author)

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

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

    1979-01-01

    The extent and structure of open unemployment in the Hashemite Kingdom of Jordan was examined. The data on unemployment in Jordan come from censuses and labor force sample surveys. The last census was conducted in 1961 and obviously cannot provide current information, but a multipurpose household survey has been conducted annually since 1972. The survey sample is a stratified multistage random sample; 3 strata are distinquished, i.e., cities, camps, and rural areas. For this survey, the unemployed are defined as those persons who are physically unable to perform work and who want work and are actively seeking work but are unemployed at present. In this analysis, those persons among the unemployed who are in the age group 12-14 are excluded. 82.3% of the unemployed in the sample were men. The total unemployment rate was 1.6%, but the rate for women was 2.8% and that for men only 1.5%. The rate for women may be overstated to an unknown extent due to underreporting of women in the labor force, yet it seems unlikely that this factor would explain all of the differences in the extent of unemployment between men and women. The cultural bias against work for women outside the home exerts an influence in making it more difficult for women to find a job, but because of this bias many women do not even enter the labor force and hence cannot be unemployed. Most of the unemployed were in the 20-24 age group and to a lesser extent in the 15-19 age group. Almost 60% of the unemployed were in these 2 age groups. Beyond these ages, the percentages of unemployed decreased regularly with age, with the age group 40-44 as a minor exception. When taking sex into account, the 1st phenomenon to be observed was the highly skewed age distribution of female unemployed who were all under age 30. Of the unemployed men, most were also young, with 34.6% in the 20-24 age group and 52.9% younger than 25 years. For married women the low unemployment rate can be explained by the fact that many

    Full Text Available Objective: Sedentary lifestyle is a major risk factor for physical and mental problems, such as cardiovascular, musculoskeletal diseases, and psychological stress. About 60% of the world’s population is not sufficiently physically active in leisure time or during work and social activities. This study aimed to determine the prevalence of inactive Jordanian adults and describe their demographic and behavioral characteristics. Methods: The study used data from the behavioral risk factors surveillance survey conducted in Jordan in 2007. The sample size was 3654. Respondents who were physically inactive for more than 240 min daily (sleep time not included were considered to have a sedentary lifestyle. Data were analyzed with the program SPSS. Results: The prevalence of a sedentary lifestyle was 82.8% (2965 respondents, with a mean sedentary time of 587 min (95% confidence interval 581–594 min. Among the physically inactive adults, 52.6% were men, one third of them aged 35–44 years. Sedentary lifestyle was reported by 30% of those with a secondary level of education or above. Of those with a sedentary lifestyle, 37.6% were housewives and 37.5% were employees; 66% of them were overweight and obese. Of the physically inactive people, 2.5% had a history of heart failure and 1.3% had a history of cerebrovascular accidents; 57.2% of them tried to engage more in physical activity and almost three quarters of them were interested in improving their dietary habits. Conclusion: Most Jordanian adults have a sedentary lifestyle, which emphasizes that there is a public health problem. Many of them are attempting to lead a healthier lifestyle. Therefore, there is an urgent need to launch an applicable national plan that enables people to practice a healthier lifestyle.

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

  14. The Minnesota notes on Jordan algebras and their applications

    CERN Document Server

    Walcher, Sebastian

    1999-01-01

    This volume contains a re-edition of Max Koecher's famous Minnesota Notes. The main objects are homogeneous, but not necessarily convex, cones. They are described in terms of Jordan algebras. The central point is a correspondence between semisimple real Jordan algebras and so-called omega-domains. This leads to a construction of half-spaces which give an essential part of all bounded symmetric domains. The theory is presented in a concise manner, with only elementary prerequisites. The editors have added notes on each chapter containing an account of the relevant developments of the theory since these notes were first written.

    2010-01-01

    This article discussed remedial activities undertaken in the Turner Valley. Remedial action in the valley must satisfy the financial concerns of engineers and investors as well as the environmental concerns of residents and regulators. Natural gas production in the Turner Valley began in 1914. The production practices were harmful and wasteful. Soil and water pollution was not considered a problem until recently. The impacts of cumulative effects and other pollution hazards are now being considered as part of many oil and gas environmental management programs. Companies know it is cheaper and safer to prevent pollutants from being released, and more efficient to clean them up quickly. Oil and gas companies are also committed to remediating historical problems. Several factors have simplified remediation plans in the Turner Valley. Area real estate values are now among the highest in Alberta. While the valley residents are generally friendly to the petroleum industry, strong communication with all stakeholders in the region is needed. 1 fig.

  20. Assessment of salt concentration in bread commonly consumed in the Eastern Mediterranean Region.

    Hypertension is the most important cardiovascular risk factor in the World Health Organization (WHO) Eastern Mediterranean Region. Excessive salt and sodium intake is directly related to hypertension, and its reduction is a priority of WHO. Bread is the leading staple food in the Region; therefore, reducing the amount of salt added to bread could be an effective measure for reducing salt intake. The study sought to determine the levels of sodium and salt in locally produced staple bread from 8 countries in the Region. Bread samples were collected randomly from bakeries located in the capital cities of the selected countries. The samples were analysed for sodium content using atomic absorption spectroscopy. The mean salt content of breads varied from 4.28 g/kg in Jordan to 12.41 g/kg in Tunisia. The mean salt and sodium content in bread for all countries was 7.63 (SD 3.12) and 3.0 (SD 1.23) g/kg, respectively. The contribution of bread to daily salt intake varied considerably between countries, ranging from 1.3 g (12.5%) in Jordan to 3.7 g (33.5%) in Tunisia. Interventions to reduce population salt intake should target reduction of salt in bread in all countries. The amount of salt added to bread should be standardized and relevant legislation developed to guide bakers. Setting an upper limit for salt content in flat bread (pita or Arabic bread) at 0.5% is strongly recommended. However, salt levels at ≤ 1% would be appropriate for other kind of breads.

    Helicobacter pylori infection is considered the most common infection worldwide and is associated with many other disorders. The aim of this study is to determine the prevalence of this infection among patients undergoing endoscopy in Northern Jordan. Between November 1998 and September 2000, all patients referred from the Gastro-esophageal Clinic to the Endoscopy Unit at Princess Basma Teaching Hospital, Irbid, Northern Jordan were enrolled in this prospective study. For each patient clinical and epidemiological data was collected and endoscopy was performed. At least 3 antral biopsies were obtained from each patient, and these were examined histologically for the presence of gastritis and stained for Helicobacter pylori using modified Giemsa stain. A total of 197 consecutive patients (113 females) with a mean age of 40.2 years (range 15-91 years) were studied. Abdominal pain was the highest presenting symptom. Gastritis 91% and esophagitis 42% were the most frequent endoscopic findings. Gastritis was documented histologically in 183 (93%) of patients. Helicobacter pylori was found in 161 patients (82%), with all of these having histological gastritis. The 11 patients with gastric ulcer, compared to the 51 out of the 59 (86%) patients with duodenal ulcer, showed Helicobacter pylori in their biopsies. The prevalence of Helicobacter pylori infection in patients subjected to an upper gastrointestinal endoscopy in Jordan is high. This study confirms that Helicobacter pylori is significantly associated with gastritis and peptic ulcer. Further studies are needed to determine the types of Helicobacter pylori strains present in Jordan. (author)

  17. THE EMISSION POTENTIAL FROM MUNICIPAL SOLID WASTE LANDFILL IN JORDAN

    Directory of Open Access Journals (Sweden)

    Mohammad Aljaradin

    2016-01-01

    Full Text Available A comprehensive study was conducted to monitor the emission potential from solid waste landfilled in Jordan over a period of 292 days using an anaerobic lysimeter. A 30 kg waste sample reflecting the typical municipal solid waste (MSW streams generated in Jordan was used to simulate the influence of climate on the emission potential of landfills located in semi-arid areas. The experimental results demonstrated that a significant amount of leachate and landfill gas was produced. The methane content was found to be more than 45% and the leachate produced reached 15.7 l after 200 days. However, after 260 days the gas and leachate production rate became negligible. A significant amount of heavy metal traces was found in the leachate due to mixed waste disposal. Changes in biogas and leachate quality parameters in the lysimeter revealed typical landfill behaviour trends, the only difference being that they developed much more quickly. In view of current landfill practices in Jordan and the effect of climate change, the results suggest that landfill design and operational modes need to be adjusted in order to achieve sustainability. For this reason, optimized design parameters and operational scenarios for sustainable landfill based on the country’s climatic conditions and financial as well as technical potential are recommended as a primary reference for future landfills in Jordan as well as in similar regions and climates.

    Full Text Available Ammar Almaaytah,1 Tareq L Mukattash,2 Julia Hajaj2 1Department of Pharmaceutical Technology, 2Department of Clinical Pharmacy, Faculty of Pharmacy, Jordan University of Science and Technology, Irbid, Jordan Objective: Current regulations in Jordan state that antibiotics cannot be sold without a medical prescription. This study aimed to assess the percentage of pharmacies that dispense antibiotics without a medical prescription in the Kingdom of Jordan and identify and highlight the extent and seriousness of such practices among Jordanian pharmacies. Methods: A prospective study was performed, and five different clinical scenarios were simulated at pharmacies investigated including sore throat, otitis media, acute sinusitis, diarrhea, and urinary tract infection in childbearing-aged women. Three levels of demand were used to convince the pharmacists to sell an antibiotic. Results: A total of 202 total pharmacies in Jordan were visited in the present study. The majority of pharmacies (74.3% dispensed antibiotics without prescription with three different levels of demand. The percentage of pharmacies dispensing antibiotics without a prescription for the sore throat scenario was 97.6%, followed by urinary tract infection (83.3%, diarrhea (83%, and otitis media (68.4%. The lowest percentage of antibiotic dispensing was for the acute sinusitis simulation at 48.5%. Among the pharmacies that dispensed antibiotics, the pharmacists provided an explanation as the number of times per day the drug should be taken in 95.3% of the cases, explained the duration of treatment in 25.7%, and inquired about allergies prior to the sale of the antibiotic in only 17.3%. Only 52 pharmacies (25.7% refused to dispense any kind of antibiotics, the majority (61.5% of this refusal response came from acute sinusitis cases, while the minority (2.4% came from the sore throat cases. Conclusion: The results of this study demonstrate that antibiotics continue to be dispensed

  14. Rapid landscape change in 6th century northern Jordan: interdisciplinary geoarchaeological perspectives

    Science.gov (United States)

    Lucke, Bernhard

    2016-04-01

    Landscapes of the ancient fertile crescent are considered affected by soil degradation as result of long-term farming since the Neolithic, and impressive ruins of antiquity led to assumptions that their abandonment must have been conntected with reduced agricultural productivity. In this context, a valley fill near the site of Abila of the Decapolis in northern Jordan was apparently deposited largely during the 6th century AD, and provides evidence for a rapid and intense landscape change during the Late Byzantine period. However, an interdisciplinary case study of land use, soil development, and sediments found that the valley fill cannot be connected with large-scale soil erosion in the vicinity of the site. On the one hand, this is indicated by the distribution of soil development and archaeological material as marker of past land use activity in the past, which suggests that the best soils were and still are used intensively. On the other hand, the sediments seem to point to the occurrence of climatic extremes such as heavy floods, the occurrence of soil creep after water saturation, but also a significant shift to aridity which may have triggered socio-economic changes of subsistence strategies from agriculture to pastoralism. The dates of sediments which are available so far indicate that the climatic change seemingly occurred rapidly within approximately 100 years during the late 6th and early 7th century AD, possibly connected with the "year without sun" or 'Mystery Veil' which the Byzantine historian Procopius described in the year 536 AD. Modern analogies of the Pinatubo eruption in 1991 let it seem possible that a volcanic event, perhaps the outbreak of the Ilopango volcano, was connected with these environmental turbulences. Such events cannot be understood by isolated studies: without a broad interdisciplinary framework, single archives are prone to misinterpretation, and our understanding of the environmental history of Abila is still very limited.

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

    Valley toward the Jordan Valley, and then into Northern Jordan. Results confirmed the previous modeling results, suggesting that peak O3 values are observed at later hours as a function of distance from the Mediterranean coast and that maximum O 3 levels are found over northern Jordan. Based on the findings of the first phase that showed elevated O 3 and NOx levels over the Gulf of Aqaba, more investigation was required to assess air quality in the city of Aqaba. Accordingly, long term air quality monitoring study conducted by Jordanian scientists was undertaken during the years 2008-2009. The study was conducted using a fixed air quality station located in the city. Results of this study indicated that topography of the city, with mountains surrounding the city from the east, played a major role in the air masses recirculation and hence the transport of primary pollutants, including NOx from the southern industrial area and the transportation emissions into the northern part of the city. However, high O3 episodes were found to be associated with northern wind in the absence of air masses recirculation indicating the role of long range transport in causing these elevated levels. Thus, based on the results of these studies and in order to reduce the potential health impacts of O3 and its precursors in downwind areas, strategies to control these pollutants should be developed. These strategies should be based on better energy, traffic and industrial management since these are the three main pollution sources. The strategies should include more efficient use of raw materials and energy, better combustion and production technologies that utilize less fuel and emit less pollutant. Measures should include controlling precursors' emissions at the sources located along the east Mediterranean coast, mainly power generation facilities, oil refineries, ports activities, and traffic. In addition, local emissions in the region such as emissions in the Gulf of Aqaba should be reduced

    The purpose of this study was to examine coping strategies used by Iraqi refugees in Jordan based on their demographic details. A cross-sectional design was used. A representative sample of 333 refugees living in Jordan participated in the study. The Cope inventory and the demographic details were compiled to produce and collate the relevant data. Being older, female, educated, single, and living with more than three family members was associated with greater use of the problem solving coping strategy. Being female, educated, and unemployed was associated with greater use of the active emotional coping strategy. In addition, being older, male, illiterate, unemployed, and living with less than three family members was associated with greater use of the avoidant emotional coping strategy. This study recommends a multidisciplinary approach intervention as being the best method of addressing and fulfilling the health and socioeconomic needs of older, male, illiterate, unemployed people.

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

    Full Text Available This paper investigates the effect of corporate governance quality on earnings management in Jordan. Using a panel data set of all industrial and service firms listed on Amman Stock Exchange (ASE during the period 2009-2013; this paper provides evidence that earnings management is affected negatively by corporate governance quality. In particular; the results show that earnings management is affected negatively by overall categories of governance index represented by board of director, board meeting, Audit and nomination and compensation committee. Furthermore, results suggest that corporate governance quality has increased over time. Thus, its ability to constrain earnings management has also increased. It is recommended to industrial and service companies to boost their compliance with corporate governance code to improve the integrity and reliability of financial reports. This paper fills a gap in the literature by providing evidence about the effect of corporate governance quality on earnings management in Jordan as an emerging economy.

    Radioactive materials are used in Jordan for peaceful applications in medicine, industry, agriculture, environmental science, education and research and military applications. Most of these radioactive sources used are imported, therefore trans-boundary movement is a significant factor in consideration of security measures during movement of these sources. After 11/9 2001 event, IAEA efforts began to focus and concentrate on security in transport of radioactive materials, after the emergence of risks of using these sources in terrorist activities. In 2002, Efforts were initiated by the IAEA to provide additional guidance for security in the transport of radioactive materials, based upon the new security requirements in the Recommendations on the Transport of Dangerous Goods. This paper reviews some of the measures relating to the transport of radioactive materials in Jordan

    Robins, Nathan

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

    The practice of pharmacy, as well as pharmacy education, varies significantly throughout the world. In Jordan, Kuwait, and Saudi Arabia, the profession of pharmacy appears to be on the ascendance. This is demonstrated by an increase in the number of pharmacy schools and the number of pharmacy graduates from pharmacy programs. One of the reasons pharmacy is on the ascendance in these countries is government commitment to fund and support competitive, well-run pharmacy programs.

    To estimate the magnitude of hypertension, and its levels of awareness and control of hypertension among a community of Jordanian aborigines in Northern Jordan; and to compare the study findings with findings from other Jordanian communities. A systematic sample of 50% of all households of Qafqafa, Northern Jordan was selected and all members of the selected households were included in the study at Qafqafa Health Center, Qafqafa, Jordan. A structured questionnaire was administered to all study participants and measurement of blood pressure was performed according to a preset criteria. Data on 366 subjects included in the sample were collected during the months of April and May 2002. A total of 40 subjects or 10.9% were suffering from hypertension. Prevalence rate of hypertension was significantly lower than the 16.1% and 16.3% prevalence rates reported from other more modernized Jordanian communities. Logistic regression analysis indicated that hypertension was positively associated with masculinity, age, illiteracy, obesity, and with positive family history of hypertension. No association was detected between hypertension and each of smoking, Diabetes mellitus, and total serum cholesterol. This study showed that one-half (47.5%) of hypertensives were unaware of their diagnosis and more than one-half (57.1%) of those aware of their diagnosis did not achieve control of their hypertension. Population of the study community has significantly lower levels of hypertension than both semi-urban and recently urbanized Jordanian communities, and much of the rise in blood pressure levels is attributed to environmental factors. Moreover, hypertension management programs in Jordan are far below the optimal standards.

    This paper presents some insights into Jordan's energy consumption in the tourist accommodation sector. The results of a recent survey on environmental performance in the tourist accommodation sector in Jordan were used to evaluate energy conservation in hotels. A survey was designed and distributed to hotels' managers and departments' supervisors in order to understand the environmental performance in the tourist accommodation sector in Jordan during the period 10-17 August 2006. Also some field visits were conducted to fully understand hotels interaction regarding the environment, in addition to help interpreting the results of the survey. The study is limited to all classified hotels in Jordan. It was found that lighting hotels' main building and outside areas, and air conditioning consume more electricity compared to other departments. The results show that few classified hotels already installed energy saving equipments, though, it was noticed that managers of one star hotels were not really willing to make such changes in their hotels, on the other hand, other classified hotels (2-5 star hotels) have shown a high willingness to make changes in their hotels to reduce the consumption of different types of energy. Hotel's classification played a significant role in explaining variations in most of the results, particularly when it comes to long-term investments to reduce energy consumption by using energy efficient appliances. Five and four star hotels were the most hotels willing to use energy efficient appliances to reduce energy consumption. The study suggested some strategies to help reduce the negative impacts of high energy consumption in hotels. These strategies include better insulation, and enhanced insulation for the hot water reticulation system.

    2014-01-01

    Senior international nuclear safety and radiation protection experts today concluded an 11-day International Atomic Energy Agency (IAEA) Integrated Regulatory Review Service (IRRS) mission to review the regulatory framework for nuclear and radiation safety in Jordan. The mission team said in its preliminary findings that Jordan's nuclear regulator, the Energy and Minerals Regulatory Commission (EMRC), faces challenges because it is a relatively new body that handles a high workload while also working to recruit, train and keep competent staff. The team also noted that a recent merger provided the regulator with more of the resources it needs to perform its duty. The team made recommendations and suggestions to the regulatory body and the Government to help them strengthen the effectiveness of Jordan's regulatory framework and functions in line with IAEA Safety Standards. The main observations of the IRRS Review team comprised the following: The regulatory body, founded in 2007 and merged with other regulators in April 2014 to form EMRC, faces large challenges in terms of its regulatory workload, management system building and staff recruitment and training; The new EMRC structure and revision of the radiation and nuclear safety law represents an important opportunity to strengthen Jordan's radiation and nuclear safety infrastructure; The Government has shown commitment to radiation and nuclear safety through measures including becoming party to international conventions. It could further demonstrate its commitment by adopting a formal national policy and strategy for safety that defines the role of the Minister of Energy in relation to EMRC and protects the independence of regulatory decision-making

    2016-01-01

    Jordan plans to import two conventional gigawatt scale nuclear reactors from Russia that are expensive and too large for Jordan's current electricity grid. Jordan efforts to establish nuclear power might become easier in some ways if the country were to construct Small Modular Reactors, which might be better suited to Jordan's financial capabilities and its smaller electrical grid capacity. But, the SMR option raises new problems, including locating sites for multiple reactors, finding water to cool these reactors, and the higher cost of electricity generation. Jordan's decision has important implications for its energy planning as well as for the market for SMRs. - Highlights: •Jordan is planning to purchase two large reactors from Russia. •Large reactors would be inappropriate to Jordan's small electricity grid. •Small modular reactors would be more appropriate to Jordan's grid, but have problems. •The market for small modular reactors will be smaller than often projected. •Jordan should consider the financial impact of building a large nuclear reactor.

    2017-08-29

    . Groundwater flows from the high-altitude recharge areas downward toward the basin-fill aquifer in Parowan Valley. Almost all groundwater discharge occurs as withdrawals from irrigation wells in the valley with a small amount of discharge from phreatophytic evapotranspiration. Subsurface groundwater discharge to Cedar Valley is likely minimal. Withdrawals from wells during 2013 were about 32,000 acre-ft. The estimated withdrawals from wells from 1994 to 2013 have ranged from 22,000 to 39,000 acre-ft per year. Declining water levels are an indication of the estimated average annual decrease in groundwater storage of 15,000 acre-ft from 1994 to 2013.Groundwater and surface-water samples were collected from 46 sites in Parowan Valley and Cedar Valley near the town of Enoch during June 2013. Groundwater samples from 34 wells were submitted for geochemical analysis. The total dissolved-solids concentration in water from these wells ranged from 142 to 886 milligrams per liter. Results of stable isotope analysis of oxygen and deuterium from groundwater and surface-water samples indicate that most of the groundwater in Parowan Valley and in Cedar Valley near Enoch is similar in isotopic composition to water from mountain streams, which reflects meteoric water recharged in high-altitude areas east of the valley. In addition, results of stable isotope analysis of a subset of samples from wells located near Little Salt Lake may indicate recharge of precipitation that occurred during cooler climatic conditions of the Pleistocene Epoch.

    Jordan's National Electric Power Company has constructed a synchronized, countrywide enterprise energy management network to provide energy companies with independent access to metering data from shared inter-tie points across the grid. The network is expected to play a key role in helping to support business processes between market participants while also providing the tools to maintain a secure and reliable source of affordable energy for the country's 5 million residents. Limited access to natural resources has placed significant constraints on the region. A background of Jordan's deregulation of the transmission grid was provided in this article, as well as details of government proposals in the past. Falling oil prices have meant an increase in involvement of private concerns in creating a sustainable business and regulatory environment. An outline of Jordan's energy assets was also provided, as well as details of the transmission system and its partitions. Details of data loggers were presented, as well as workstation terminals. Security safeguards such as a segmented network infrastructure, data validation and multilevel user authentication ensure that all billing and operational data is secure. Issues concerning revenue accuracy were discussed. It was concluded that a reliable metering and communications infrastructure is helping to support business processes between market participants. 3 figs.

    2004-01-01

    With rapid population growth and increase in industrial activities, more energy is consumed, resulting in environmental pollution and economic difficulties. Therefore, the need for utilising renewable energy resources has emerged. Although Jordan does not have adequate fuel supplies (90% of its crude oil is imported), it is gifted with alternative resources. Because of the political and economical constraints that hinder the import of crude oil from neighbouring countries and of the fact that Jordan has limited fossil fuel resources, strategies to meet energy demand are being addressed and examined together with their consequences and the ways in which they could be utilised. This paper assesses for the first time, the potential of using alternative energy technologies in Jordan, including the utilisation of solar energy for water heating, for wind towers in rural areas and also for biogas production from waste. Approximately 2% of unconventional renewable energy resources are being utilised. The data and scenarios of this study were presented in a manner that would assist decision makers, funding agencies, researchers and other related parties to establish programmes that will be helpful in meeting the energy demand, while preserving the environment and maintaining sustainability.

    Voluminous stockpiles of phosphogypsum (PG) generated during the wet process production of phosphoric acid are stored at many sites around the world and pose problems for their safe storage, disposal, or utilization. A major concern is the elevated concentration of long-lived 226Ra (half-life = 1,600 years) inherited from the processed phosphate rock. Knowledge of the abundance and mode-of-occurrence of radium (Ra) in PG is critical for accurate prediction of Ra leachability and radon (Rn) emanation, and for prediction of radiation-exposure pathways to workers and to the public. The mean (??SD) of 226Ra concentrations in ten samples of Jordan PG is 601 ?? 98 Bq/kg, which falls near the midrange of values reported for PG samples collected worldwide. Jordan PG generally shows no analytically significant enrichment (age of PG. Water-insoluble residues from Jordan PG constitute environmental mobility of radium and the radiation-exposure pathways near PG stockpiles. ?? 2010 US Government.

    2015-07-01

    Full Text Available This study examines the impact of the environmental policy in Jordan. The article reviews laws, measures, instruments and the implementation process and evaluates their effectiveness in banning, removing and/or reducing negative externalities in Jordan. Data was collected by administration of questionnaires distributed to all key enforcement officials working in the Ministries of Environment, Agriculture, and Health. Additional sources were laws, regulations, official documents and reports issued by the government, international organizations, NGOs and media. The study shows that Jordan’s environmental policy relies solely on the command and control approach to mitigate negative externalities, while completely overlooking price-based and rights -based instruments. Such instruments are widely and increasingly employed in developed countries and have proved their efficiency and effectiveness in protecting the environment. The results of the study reveal that command and control measures are insufficient to achieve effective environmental policy and consequently are incapable of internalizing negative externalities in Jordan. The results may motivate government regulators to endorse price-based and rights-based measures, in addition to command and control measures.

    1997-01-01

    Oil shale is the major indigenous fossil-fuel in Jordan: its predicted reserves, of about 5·10 1 0 tonnes, should be sufficient to satisfy Jordan's energy requirements for several centuries. Jordanian oil shale has, on an average, a gross calorific value of between 5 and 7 MJ/kg, an oil yield of ∼ 10 %, and a sulfur content of approximately 3 % by weight of the raw shale (i.e. 7 to 9 % of the organic matter content). Using the oil shale as the input fuel, a multipurpose production process (i.e. retorting, electricity generation, thermal water-desalination, chemicals production as well as mineral extraction) could achieve high utilisation-factors of both its chemical and energy potentials. In the long-term, oil shale is the only indigenous energy resource that could reduce Jordan's dependence on imported crude oil and hence ease the pressure on the national economy. The conversion of oil shale into a liquid or gaseous fuel and raw materials will be of decisive importance in attempts to secure the future of energy supplies. So national efforts devoted to the exploration for, and harnessing more economically, this energy resource, while limiting the associated adverse environmental impacts, should be accelerated.

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

    1995-08-01

    If excess water salinity is to be managed in the Hunter Valley, its causes and behaviour must be understood. Although Hunter Valley hydrology, hydrogeology and hydrogeochemistry require further study, there is now enough information available to begin the development of both temporal and spatial models as valley management tools. Currently the Department of Water Resources is developing a model known as Integrated Water Quality and Quantity Model (IQQM). IQQM which includes a salinity module is essentially a surface water simulation model. It wll enable testing of alternate management and operation policies such as the salinity property rights trading scheme recently introduced by the EPA to manage salt release from coal mines and power stations. An overview is presented of the progress made to date on the salinity module for IQQM, and an outline is given of the geological and hydrogeochemical concepts that have been assembled to support the salinity module of IQQM. 17 refs., 3 figs., 1 tab.

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

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

    2015-04-01

    Climate change represents one of the greatest environmental, social and economic threats facing Jordan. In particular, the combined effects of climate change and water scarcity threaten to affect food and water resources that are critical for livelihoods in Jordan. This is especially true for those communities who live in the dryland area in the country and who rely wholly on rain-fed agriculture. The exact nature and extent of the impact of climate change on temperature and precipitation distribution pattern remain uncertain and it is the poor and vulnerable who will be the most susceptible to climate change adverse effects. A vulnerability assessment of rain fed agriculture to climate change and variability in semi-arid parts of Jordan was conducted in 2014. The purpose of this study is to assess the vulnerability and resilience of the most vulnerable groups where rainfed and irrigated agriculture is practiced. Also, the study focused on quantifying the impacts on agricultural productivity in response to climate change. This will help policymakers and researchers better understand and anticipate the likely impacts of climate change on agriculture and on vulnerable communities in Jordan. Also, it will provide them with tools to identify and implement appropriate adaptation strategies. The data used includes; Representative Concentration Pathways (RCPs), RCP 4.5 and RCP 8.5 adopted by the IPCC for its fifth Assessment Report (AR5). Those pathways were used for climate modeling. A decision support system (DSSAT) for agricultural production was used to assess the impact of climate changes on agricultural production. This approach was used for the Identification of climate change risk and their impacts on Agriculture. Outputs from models are used to assess the vulnerability of farmers and crops to climate and socio-economic change by estimating their sensitivity and capacity to adapt to external factors as a means of identifying what causes the differences in their

    Purpose The purpose of this paper is to determine water availability, sanitation and hygiene (WSH) services, and healthcare waste management in Jordan healthcare facilities. Design/methodology/approach In total, 19 hospitals (15 public and four private) were selected. The WSH services were assessed in hospitals using the WSH in health facilities assessment tool developed for this purpose. Findings All hospitals (100 percent) had a safe water source and most (84.2 percent) had functional water sources to provide enough water for users' needs. All hospitals had appropriate and sufficient gender separated toilets in the wards and 84.2 percent had the same in outpatient settings. Overall, 84.2 percent had sufficient and functioning handwashing basins with soap and water, and 79.0 percent had sufficient showers. Healthcare waste management was appropriately practiced in all hospitals. Practical implications Jordan hospital managers achieved major achievements providing access to drinking water and improved sanitation. However, there are still areas that need improvements, such as providing toilets for patients with special needs, establishing handwashing basins with water and soap near toilets, toilet maintenance and providing sufficient trolleys for collecting hazardous waste. Efforts are needed to integrate WSH service policies with existing national policies on environmental health in health facilities, establish national standards and targets for the various healthcare facilities to increase access and improve services. Originality/value There are limited WSH data on healthcare facilities and targets for basic coverage in healthcare facilities are also lacking. A new assessment tool was developed to generate core WSH indicators and to assess WSH services in Jordan's healthcare facilities. This tool can be used by a non-WSH specialist to quickly assess healthcare facility-related WSH services and sanitary hazards in other countries. This tool identified some areas

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

    Full Text Available This article responds to Jordan Wessling’s paper that engages a concern I expressed about analytic theology not doing justice to the sapiential requirements of theology. I examine Wessling’s summary of my paper, conclude that his description is accurate and fair, appreciate his proposed solution, then go on to restate why I think he may not have fully allayed my concern. I suggest that analytic theology is a vital tool in the theologian’s toolkit, but that ultimately more is needed in order to interpret Scripture theologically.

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

    Turner, Brian R.; Makhlouf, Issa M.; Armstrong, Howard A.

    2005-11-01

    The Late Ordovician (Ashgillian) glacial deposits in southern Jordan, comprise a lower and upper glacially incised palaeovalley system, occupying reactivated basement and Pan-African fault-controlled depressions. The lower palaeovalley, incised into shoreface sandstones of the pre-glacial Tubeiliyat Formation, is filled with thin glaciofluvial sandstones at the base, overlain by up to 50 m of shoreface sandstone. A prominent glaciated surface near the top of this palaeovalley-fill contains intersecting glacial striations aligned E-W and NW-SE. The upper palaeovalley-fill comprises glaciofluvial and marine sandstones, incised into the lower palaeovalley or, where this is absent, into the Tubeiliyat Formation. Southern Jordan lay close to the margin of a Late Ordovician terrestrial ice sheet in Northwest Saudi Arabia, characterised by two major ice advances. These are correlated with the lower and upper palaeovalleys in southern Jordan, interrupted by two subsidiary glacial advances during late stage filling of the lower palaeovalley when ice advanced from the west and northwest. Thus, four ice advances are now recorded from the Late Ordovician glacial record of southern Jordan. Disturbed and deformed green sandstones beneath the upper palaeovalley-fill in the Jebel Ammar area, are confined to the margins of the Hutayya graben, and have been interpreted as structureless glacial loessite or glacial rock flour. Petrographic and textural analyses of the deformed sandstones, their mapped lateral transition into undeformed Tubeiliyat marine sandstones away from the fault zone, and the presence of similar sedimentary structures to those in the pre-glacial marine Tubeiliyat Formation suggest that they are a locally deformed facies equivalent of the Tubeiliyat, not part of the younger glacial deposits. Deformation is attributed to glacially induced crustal stresses and seismic reactivation of pre-existing faults, previously weakened by epeirogenesis, triggering sediment

    Purpose The purpose of this paper is to present the deficiencies in teamwork skills at Jordan hospitals as seen by team members. The study aims to identify training needs to improve teamwork-related soft skills of caregivers to enhance staff satisfaction and improve quality of care. Moreover, the paper provides a methodology to identify the training needs in any healthcare workplace by repeating the same questionnaire. Design/methodology/approach A self-administrated questionnaire was designed to study deficiencies in teamwork and team leadership at Jordan hospitals as seen by team members. Surveyed care providers included physicians, nursing and anesthesiologists operating in emergency departments, surgical operating rooms and intensive care units from various hospitals. Findings With a response rate of 78.8 percent, statistical analysis of collected data of opposing staff members revealed low levels of satisfaction (40.7-48 percent opposing), lack of awareness on the impact of teamwork on quality of care (15.6-22.1 percent opposing), low levels of involvement of top management (27.1-57.3 percent opposing), lack of training (52.5-69.8 percent opposing), lack of leadership skills (29.8-60 percent opposing), lack of communication (22.3-62.1 percent opposing), lack of employee involvement (37.6-50.8 percent opposing) and lack of collaboration among team members (28.6-50 percent opposing). Among the many, results illustrate the need for improving leadership skills of team leaders, improving communication and involving team members in decision making. Originality/value Several studies investigated relationships between teamwork skills and quality of care in many countries. To the authors' knowledge, no local study investigated the deficiencies of teamwork skills among Jordan caregivers and its impact on quality of care. The study provides the ground for management at Jordan hospitals and to healthcare academic departments to tailor training courses to improve teamwork

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

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

    2016-04-01

    Full Text Available This research shows a case from Jordan where geospatial techniques were utilized for irrigation water auditing. The work was based on assessing records of groundwater abstraction in relation to irrigated areas and estimated crop water consumption in three water basins: Yarmouk, Amman-Zarqa and Azraq. Mapping of irrigated areas and crop water requirements was carried out using remote sensing data of Landsat 8 and daily weather records. The methodology was based on visual interpretation and the unsupervised classification for remote sensing data, supported by ground surveys. Net (NCWR and gross (GCWR crop water requirements were calculated by merging crop evapotranspiration (ETc, calculated from daily weather records, with maps of irrigated crops. Gross water requirements were compared with groundwater abstractions recorded at a farm level to assess the levels of abstraction in relation to groundwater safe yield. Results showed that irrigated area and GCWR were higher than officially recorded cropped area and abstracted groundwater. The over abstraction of groundwater was estimated to range from 144% to 360% of the safe yield in the three basins. Overlaying the maps of irrigation and groundwater wells enabled the Ministry of Water and Irrigation (MWI to detect and uncover violations and illegal practices of irrigation, in the form of unlicensed wells, incorrect metering of pumped water and water conveyance for long distances. Results from the work were utilized at s high level of decision-making and changes to the water law were made, with remote sensing data being accredited for monitoring water resources in Jordan.

    Al Khalaileh, Murad; Al Qadire, Mohammad

    Pain management requires knowledgeable and trained nurses. Because nursing students are the nurses of the future, it is important to ensure that students receive adequate education about pain management in nursing schools. The purpose of this study is to evaluate nursing students' knowledge and attitudes regarding pain management. A cross-sectional survey was used. The sample comprised 144 students from three nursing colleges in Jordan. Sixty-one percent were female and the average age was 21.6 years (SD 1.7). The students' Knowledge and Attitudes Survey Regarding Pain was used. The rate of correct answers ranged from 11.1% to 64%. Students showed a low level of knowledge regarding pain management-the average score was just 16 (SD 5.11) out of 40. Students were weak in their knowledge of pain medications pharmacology (actions and side effects). Less than half of students (47.9%) recognised that pain may be present, even when vital signs are normal and facial expressions relaxed. Finally, students showed negative attitudes towards pain management, believing that patients should tolerate pain as much as they can before receiving opioids; almost half (48%) of students agreed that patients' pain could be managed with placebo rather than medication. In conclusion, Jordanian nursing students showed lower levels of pain knowledge compared with other nursing students around the world. This study underlines the need to include pain-management courses throughout undergraduate nursing curricula in Jordan.

    Magistracy are common in tuff and paralytic's materials of Pleistocene age in western Jordan. The dominant phases are olivine, augite, plagioclase, magnetite and ilmenite. Chemical analysis of the whole rocks samples indicate alkali olivine magma origin. Low concentration of Li and Rb in Tuff samples are used as an argument against the contamination of the basaltic magma during its journey to the surface. The Mg O and mg- values (Mg/Mg+Fe 2+ ) in samples from volcano exhibit different degrees of fractionation, which are indicated by the varying concentrations of incompatible trace elements (Ba, Rb, Sr). The thermometric evacuation of tuff formation by using pyroxenes thermometers revealed a temperature range between 1022-1083 deg. and pressure of 5-10 K bars. The low Mg-ratio (Mg/Mg+Fe 2+ ) is due to fractional crystallization of olivine and pyroxene in tuff samples. The variation of incompatible elements imply derivation from a peridotite source in the upper mantle with low degree of melting (<20%).The volcanic activity took place in phases corresponding to rifting sinistral displacement along the Jordan Rift.

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

    Full Text Available Pleurotus is considered an important genus that belongs to the family Pleurotaceae and includes the edible King Oyster mushroom (Pleurotus eryngii. In the present study, 19 Pleurotus isolates were collected from two locations in the north of Jordan (Tell ar-Rumman and Um-Qais. The morphological characteristics among collected isolates revealed that there was a morphological similarity among the collected isolates. Nucleotide sequence analysis of the internal transcribed spacer (ITS1–5.8S rDNA–ITS4 region and 28S nuclear large subunit (nLSU in the ribosomal DNA gene of the isolated stains showed that all of them share over 98% sequence similarity with P. eryngii. Genetic diversity among the collected strains was assessed using inter simple sequence repeat (ISSR analysis using 18 different primer pairs. Using this approach, 141 out of 196 bands obtained were considered polymorphic and the highest percentage of polymorphism was observed using primer UBC827 (92.3% with an overall Polymorphism Information Content (PIC value of 70.56%. Cluster analysis showed that the Jordanian Pleurotus isolates fall into two main clades with a coefficient of similarity values ranging from 0.59 to 0.74 with a clear clustering based on collection sites. The results of the present study reveal that molecular techniques of ISSR and rDNA sequencing can greatly aid in classification and identification of Pleurotus spp. in Jordan.

    Recently increasing evidence has been provided pointing to a close relation of salt consumption to hypertension as well as to target organ damage. It is interesting to note that the discussion concerning salt is unusually emotional. This may be explained, at least in part, by the fact that since ancient times salt had deep symbolic significance, as exemplified, mostly subconsciously, by many customs and expressions still in current use. In the past salt was essential to preserve food. The past importance of salt as a commodity can well be compared with that of oil today. These and further historical aspects of the role of salt are briefly dealt with in this article.

    Breast cancer is the most common cancer, and one of the leading causes of death for females in Jordan and many countries in the world. Studies have shown that delay in symptoms presentation, diagnosis or treatment would result in poor prognosis. There has been no published study from Jordan on delays in patient presentation, delays in diagnosis, or delays in treatment. Therefore, we conducted this study to assess these important quality indicators aiming to improve prognosis for breast cancer patients in Jordan. This project was a cross-sectional study on female breast cancer patients in Jordan. The total number of participants was 327. The proportion of patients with presentation delay, diagnosis delay, and treatment delay was 32.2%, 49.1%, or 32.4%, respectively. The main reported reasons for delay in presentation were ignorance of the nature of the problem (65.6%), limited/lack of knowledge that symptoms were suggestive of cancer diagnosis (16.7%), and misdiagnosis (16.7%). Predictors of delay and mean time for presentation, diagnosis, and treatment were identified. Our results reveal that breast cancer patients in Jordan are experiencing delays in presentation, diagnosis, and treatment. This could justify the advanced stages at diagnosis and poor outcomes for breast cancer patients in Jordan. We recommend revising the current early detection and down-staging programs in Jordan. © 2015 Wiley Periodicals, Inc.

    Saturated Quaternary deposits in the Sugar Horse quadrangle supply significant quantities of water to wells from which water is withdrawn for domestic, municipal, industrial, and irrigation uses. The deposits consist of clay, silt, sand, and gravel; individual beds range from a few inches to several tens of feet thick. The principal aquifer, which is almost completely within the Quaternary deposits, supplied about 4 percent, or 9,000 acre-feet, of the municipal and industrial water used annually in Salt Lake County during 1964-68.As a general rule, more water is stored and more water will be yielded to a well where aquifers are thicker. This map can be used as a general guide to those areas where greatest amounts of water are stored in the aquifer, and where yields to wells may be greater. Local variations in the ability of saturated deposits to transmit water can alter the general relationship between aquifer thickness and yield of wells.The thickness of saturated Quaternary deposits within the area of the Sugar Horse quadrangle ranges from zero to about 650 feet, as shown on the map. The thickest section of these deposits is near the southwestern corner of the quadrangle, and the thinnest section is along the mountain front adjacent to the approximate eastern limit of saturated Quaternary deposits.The thickness of saturated Quaternary deposits shown on this map is based on drillers’ logs for 55 deep wells (which show the thickness of the Quaternary deposits) and on water-level measurements made in February 1972 in wells in unconfined shallow aquifers.Reports in the following list of selected references contain other information about the saturated Quaternary deposits in this and adjacent parts of Jordan Valley, Utah. The basic-data reports and releases contain well logs, water-level measurements, and other types of basic ground-water data.

  13. The California Valley grassland

    Grasslands are distributed throughout California from Oregon to Baja California Norte and from the coast to the desert (Brown 1982) (Figure 1). This review will focus on the dominant formation in cismontane California, a community referred to as Valley Grassland (Munz 1959). Today, Valley Grassland is dominated by non-native annual grasses in genera such as Avena (wild oat), Bromus (brome grass), and Hordeum (barley), and is often referred to as the California annual grassland. On localized sites, native perennial bunchgrasses such as Stipa pultra (purple needle grass) may dominate and such sites are interpreted to be remnants of the pristine valley grassland. In northwestern California a floristically distinct formation of the Valley Grassland, known as Coast Prairie (Munz 1959) or Northern Coastal Grassland (Holland and Keil 1989) is recognized. The dominant grasses include many native perennial bunchgrasses in genera such as Agrostis, Calamagrostis, Danthonia, Deschampsia, Festuca, Koeleria and Poa (Heady et al. 1977). Non-native annuals do not dominate, but on some sites non-native perennials like Anthoxanthum odoratum may colonize the native grassland (Foin and Hektner 1986). Elevationally, California's grasslands extend from sea level to at leas 1500 m. The upper boundary is vague because montane grassland formations are commonly referred to as meadows; a community which Munz (1959) does not recognize. Holland and Keil (1989) describe the montane meadow as an azonal community; that is, a community restricted not so much to a particular climatic zone but rather controlled by substrate characteristics. They consider poor soil-drainage an over-riding factor in the development of montane meadows and, in contrast to grasslands, meadows often remain green through the summer drought. Floristically, meadows are composed of graminoids; Cyperaceae, Juncaceae, and rhizomatous grasses such as Agropyron (wheat grass). Some bunchgrasses, such as Muhlenbergia rigens, are

    Rift Valley fever (RVF) is a severe veterinary disease of livestock that also causes moderate to severe illness in people. The life cycle of RVF is complex and involves mosquitoes, livestock, people, and the environment. RVF virus is transmitted from either mosquitoes or farm animals to humans, but is generally not transmitted from person to person. People can develop different diseases after infection, including febrile illness, ocular disease, hemorrhagic fever, or encephalitis. There is a significant risk for emergence of RVF into new locations, which would affect human health and livestock industries. Copyright © 2017 Elsevier Inc. All rights reserved.

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

    The Lower Jordan River, once a flowing freshwater river, is suffering from an ongoing reduction of discharge and water quality. The river flows between the Sea of Galilee and the Dead Sea, an aerial distance of about 105 Km. The severe reduction is caused by an excessive exploitation of its sources and diversion of sewage and agricultural drainage into the river. The extreme low flows and low water quality threaten the natural existence of the river and its potential use for agriculture. In spite of its importance, little research has been done in the river. The objectives of the study were to measure the discharge and water composition along the river and to evaluate the main sources that control its flow and chemical characteristics. The hypothesis of the study was that interaction with subsurface flows significantly affects the river flow and chemical composition. The research is based on a detailed field study, which included flow rate measurements in the river and its tributaries, water sampling and analysis and mass balance calculations of water and solutes. A portable Acoustic Doppler Velocimeter (ADV) was used to measure velocities and bathymetry at different locations across the river sections. Due to accessibility constraints, a floating traverse construction, which enables the ADV's deployment from one bank of the river, was developed. It was found that flow rate ranges between 500-1,100 L/s in northern (upstream) sections and 300-1,650 L/s in the south. This low discharge represents a significant reduction from historical values and is lower than recent published estimations. This research represents base flows only, as the measurements were done during a period of two consecutive draught years. Calculated mass balance of water flows in the northern sections shows that the subsurface source contributes to the river around 200-670 L/s (30-80% of the river flow). Calculations of solute balance show that the subsurface flows add 20-50% of the mass of

    These paper intents a brief description of the evolution that characterised natural risk prevention in the area surrounding the city of Medellin, Colombia, called the Aburra Valley. Both the lithological and structural composition of the Valle and its topographic and climatic conditions contribute to the abundance of destructive natural phenomena as earthquakes, slope movements, flash floods and, in a lower proportion, to floods. The population increase, which reaches now 3.5 millions inhabitants and the frequent occupation of sites exposed to natural hazards have resulted in numerous disasters. At present two entities called SIMPAD and DAPARD work on risk prevention, on city and department scale respectively. The amount of knowledge about physical environment is considered to be insufficient, together with regulations which should direct land use in accordance to restrictions related to natural hazards. Several seminars on this topic have already been carried out and the organisers of the present one, destined to commemorate the twentieth anniversary of the Villatina disaster, should make the decision to meet each two years. Furthermore, the creation of a permanent commission dedicated to study past events, to foster information broadcasting and to seek a better knowledge of the Aburra Valley, should be considered

    The environmental impact of olive mill wastewater (OMW) pollution is a public concern. OMW contains high levels of phenols, organic compounds, chemical oxygen demand (COD), biological oxygen demand (BOD), microorganisms, nutrients, and toxic compounds. The treatment of OMW has been investigated by many researchers in the Mediterranean region, using several treatment techniques to remove contaminants from OMW. These techniques include chemical, biological, physiochemical, and biophysical techniques. Surfactants and some adsorbents were used in chemical techniques, anaerobic and aerobic in biological techniques, while the combined treatment methods used Electroosmosis, ozonation and electrocoagulation processes as physiochemical methods, and ultrasonic irradiation combined with aerobic biodegradation as biophysical method. The effects of OMW, whether treated or untreated, have been evaluated on both plants’ growth and soil properties. The treatment methods as well as the environmental impact of OMW in Jordan were summarized in this review.

    Full Text Available In a study on grapevines in Jordan conducted between 2002 and 2003, grapevine virus A (GVA was detected in all areas where grapevines were planted. DAS-ELISA analysis of samples from symptomatic trees found that 16.1% of samples were infected with GVA. Using a GVA- specific primer pair (H587/C995, a portion of the coat protein gene of the virus was amplified by IC-RT-PCR and RT-PCR, using leaf extracts and RNA extracted from infected grapevines respectively. After cloning and sequencing the coat protein gene of the Jordanian isolate of GVA (GVA-Jo, the sequence of the amplified product was compared with sequences of other GVA isolates from different countries.

A total of 2552 samples were collected from 72 commercial orchards, a mother block, 15 nurseries, and a varietal collection. A total of 208 almond, 451 apricot, 149 cherry, 250 nectarine, 1016 peach, and 478 plum trees were tested individually for PNRSV by the double-antibody sandwich enzyme linked immunosorbent assay (DAS-ELISA. Around 15% of tested samples were infected with PNRSV. The virus incidence in almond, nectarine, plum, peach, cherry, and apricot was 24, 16, 16, 14, 13, and 10% of tested trees respectively. The level of viral infection was highest in the mother block (19%, and lowest in the samples from the nurseries (10%.

    2001-01-01

    Radon emanation was sampled in five locations in a limestone quarry area using SSNTDs CR-39. Radon levels in the soil air at four different well-known traceable fault planes were measured along a traverse line perpendicular to each of these faults. Radon levels at the fault were higher by a factor of 3-10 than away from the faults. However, some sites have broader shoulders than the others. The method was applied along a fifth inferred fault zone. The results show anomalous radon level in the sampled station near the fault zone, which gave a radon value higher by three times than background. This study draws its importance from the fact that in Jordan many cities and villages have been established over an intensive faulted land. Also, our study has considerable implications for the future radon mapping. Moreover, radon gas is proved to be a good tool for fault zones detection

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

    Alkaptonuria is a rare autosomal recessive metabolic disorder characterized by a deficiency of homogentisate 1,2-dioxygenase (HGO) in the liver. This results in excretion of large quantities of homogentisic acid (HGA) (also called alkapton) in the urine and a slowly progressive deposition of homogentisic acid and its oxidative product in connective tissues. Clinical characteristic features of alkaptonuria are darkening of urine, bluish-dark pigmentation of connective tissues (ochronosis) and arthritis of large joints and spine. Cardiovascular and genitourinary systems may also be affected. In this report, we present the initial results of screening family members with history of alkaptonuria in southern region of Jordan. We present 9 cases of alkaptonuria (two males and seven females) in one Jordanian family. The history, signs and symptoms, diagnostic techniques and treatment options of alkaptonuria are reviewed in this article.

    This paper discusses the type of work migrant women from the former Eastern European countries perform in nightclubs in Amman, Jordan. The fieldwork for this qualitative study was conducted in 2010 and is based on in-depth interviews with 13 women. The topic is approached from the perspective of describing women's choices and journeys to this work. It juxtaposes the sexualised nature of their work with their yearning for a "normal" family life, which they imagine, yet know, is impossible to achieve with the men they meet in their workplaces. Layered on top of these private desires among both women and their clients is the business strategy of the clubs, which operate in the lucrative but marginal space of selling exotic but respectable seduction. I draw on the literature about female migration to the Middle East in order to argue that hostesses in these bars perform affective labour akin to care work, within the neoliberal global economy that individualises risk.

    The Bouguer gravity field over the northwestern Arabian Platform in Jordan is dominated by large variations, ranging from -132 to +4 mGal. A study of the Bouguer anomaly map shows that the gravity field maintains a general north-northeasterly trend in the Wadi Araba-Dead Sea-Jordan Riff, Northern Highlands and Northeast Jordanian Limestone Area, while the remainder of the area shows north-northwesterly-trending gravity anomalies. Results of 2-D gravity modeling of the Bouguer gravity field indicate that the crustal thickness in Jordan is ˜ 38 km, which is similar to crustal thicknesses obtained from refraction data in northern Jordan and Saudi Arabia, and from gravity data in Syria.

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

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

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

    Full Text Available Knowledge and awareness about occupational therapy (OT are essential for the delivery of quality care to all clients and for occupational therapists’ (OTRs job satisfaction. OT has been a poorly understood profession in Jordan. The current study reports on the assessment of Jordanians’ awareness and knowledge of occupational therapy. Convenience sampling was used. There were 829 participants (474 males, 355 females, with mean age of 32 ± 11.6 yrs. They were recruited from the three main geographical areas of Jordan (northern, central, and southern and from all educational levels. The sample included 222 (26.8% healthcare personnel, 146 (17.6% clients, and 461 (55.6% lay persons. Participants completed questionnaires, and the results revealed that 48% of the sample had poor or no knowledge about OT, while 28.3% were unaware of it. Also, OT was commonly (50% perceived to be exclusively targeting people with disabilities (PWDs and neurological and physical conditions (58% and 53%, resp. in addition to exclusively providing services for the rehabilitation of the upper extremity (48%. Common misconceptions associated with OT were that OTRs prescribe medication (43% and OTRs are physiotherapists (44%. These preliminary findings suggest that efforts need to be directed by OTRs, the Jordanian Society of Occupational Therapy (JSOT, and the Ministry of Health to preserve the OT identity and value and promote knowledge about OT in the public and among members of interdisciplinary teams. More interprofessional learning needs to be incorporated within the curricula and placements of all healthcare personnels.

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

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

    A national energy plan must be formulated to be applied in the near future concerning energy sources supplies in Jordan. The important issue is that Jordan must secure energy supplies from new sources, and therefore the plan must cover all aspects of energy consumption as domestic, industrial, heating and transport as well as storage facilities. The plan must aim at decreasing consumption rates rationing in order to guarantee a continuous and adequate of energy supplies. (S.T.). 2 tabs., 1 fig

    Consanguinity is a deep rooted cultural trait in Jordan. To examine the patterns and determinants of declining rates of consanguineous marriage in Jordan during 1990-2012 in the context of the changing pattern of socio-economic and demographic conditions. The data come from the 1990 and 2012 Jordan Population and Family Health Surveys (JPFHSs). A total of 6461 women in 1990 and 11,352 women in 2012 were successfully interviewed. Descriptive and multivariate statistical techniques were used for data analysis. Consanguinity was found to be widely practiced (35% in 2012) until recent times in Jordan. However, there has been a secular declining trend over the last few decades as the practice of consanguinity has declined from 56% in 1990 to 35% in 2012. Increasing age at marriage and female education, higher level of education of husbands, declining family size, increasing rate of urbanisation and female employment, exposure to mass media and higher economic status appeared as significant predictors of declining consanguinity in Jordan. The findings of this study support Goode's hypothesis of a decrease of consanguinity with modernisation. Although consanguinity is a deeply rooted cultural trend in Jordan, it is gradually losing ground due to modernisation and socio-demographic transition of the country.

    An evaluation of Jordan's bio-energy status was carried out. Available sources and the viability of exploitation were studied in order to identify the size of contribution that bio-energy could provide to the total energy mix of the Kingdom. The advantages of biogas technology were discussed, and a general description of Jordan's experience in this field was presented. Data on Jordan' animal, municipal, and agricultural wastes that are available as a potential source of bio-energy was tabulated. The report ascertained the economic feasibility of biogas utilization in Jordan, and concluded that the annual energy production potential from biogas, with only animal wastes being utilized, would amount to 80,000 ton oil equivalent. This amount of energy is equivalent to 2% of Jordan's total energy consumption in 1992. The utilization of biogas from municipal wastes would produce an additional 2.5% of the total energy consumption of Jordan. The annual value of utilizing animal and municipal wastes would reach 23 million Jordanian Dinars (JD). This value would increase to 61.5 million JD with the utilization of human wastes. The investment required for the utilization of bio-energy sources in Amman and its suburbs on the scale of family unit fermenters was estimated to be in the order of a million JD. The size of investment for industrial scale utilization for power generation with an electricity feed to the national grid, would range from 3 to 4 million JD. (A.M.H.). 8 refs., 4 tabs

  6. Technical Analysis of In-Valley Drainage Management Strategies for the Western San Joaquin Valley, California

    2008-01-01

    The western San Joaquin Valley is one of the most productive farming areas in the United States, but salt-buildup in soils and shallow groundwater aquifers threatens this area?s productivity. Elevated selenium concentrations in soils and groundwater complicate drainage management and salt disposal. In this document, we evaluate constraints on drainage management and implications of various approaches to management considered in: *the San Luis Drainage Feature Re-Evaluation (SLDFRE) Environmental Impact Statement (EIS) (about 5,000 pages of documentation, including supporting technical reports and appendices); *recent conceptual plans put forward by the San Luis Unit (SLU) contractors (i.e., the SLU Plans) (about 6 pages of documentation); *approaches recommended by the San Joaquin Valley Drainage Program (SJVDP) (1990a); and *other U.S. Geological Survey (USGS) models and analysis relevant to the western San Joaquin Valley. The alternatives developed in the SLDFRE EIS and other recently proposed drainage plans (refer to appendix A for details) differ from the strategies proposed by the San Joaquin Valley Drainage Program (1990a). The Bureau of Reclamation (USBR) in March 2007 signed a record of decision for an in-valley disposal option that would retire 194,000 acres of land, build 1,900 acres of evaporation ponds, and develop a treatment system to remove salt and selenium from drainwater. The recently proposed SLU Plans emphasize pumping drainage to the surface, storing approximately 33% in agricultural water re-use areas, treating selenium through biotechnology, enhancing the evaporation of water to concentrate salt, and identifying ultimate storage facilities for the remaining approximately 67% of waste selenium and salt. The treatment sequence of reuse, reverse osmosis, selenium bio-treatment, and enhanced solar evaporation is unprecedented and untested at the scale needed to meet plan requirements.

    Work in progress on Hawaiian drainage evolution indicates an important potential for understanding drainage development on Mars. Similar to Mars, the Hawaiian valleys were initiated by surface runoff, subsequently enlarged by groundwater sapping, and eventually stabilized as aquifers were depleted. Quantitative geomorphic measurements were used to evaluate the following factors in Hawaiian drainage evolution: climate, stream processes, and time. In comparing regions of similar climate, drainage density shows a general increase with the age of the volcani island. With age and climate held constant, sapping dominated valleys, in contrast to runoff-dominated valleys, display the following: lower drainage densities, higher ratios of valley floor width to valley height, and more positive profile concavities. Studies of stream junction angles indicate increasing junction angles with time on the drier leeward sides of the major islands. The quantitative geomorphic studies and earlier field work yielded important insights for Martian geomorphology. The importance of ash mantling in controlling infiltration on Hawaii also seems to apply to Mars. The Hawaiian valley also have implications for the valley networks of Martian heavily cratered terrains

    Located in the arid basalt desert of northeastern Jordan, the Early Bronze Age (EBA) settlement of Jawa is by far the largest and best preserved archaeological EBA site in the region. Recent surveys in the close vicinity revealed well-preserved remains of three abandoned agricultural terrace systems. In the presented study these archaeological features are documented by detailed mapping and the analysis of the sediment records in a multi-proxy approach. To study the chronology of the terrace systems optically stimulated luminescence (OSL) is used. In order to evaluate the efficiency of the water management techniques and its impact on harvest yields, a crop simulation model (CropSyst) under today's climatic conditions is applied, simulating crop yields with and without (runoff) irrigation. In order to do so, a runoff time series for each agricultural terrace system and its catchment is generated, applying the SCS runoff curve number method (CN) based on rainfall and soil data. Covering a total area of 38 ha, irrigated terrace agriculture was practiced on slopes, small plateaus, and valleys in the close vicinity of Jawa. Floodwater from nearby wadis or runoff from adjacent slopes was collected and diverted via surface canals. The terraced fields were arranged in cascades, allowing effective water exploitation through a system of risers, canals and spillways. The examined terrace profiles show similar stratigraphic sequences of mixed unstratified fine sediments that are composed of small-scale relocated sediments with local origin. The accumulation of these fines is associated with the construction of agricultural terraces, forcing infiltration and storage of the water within the terraces. Two OSL ages of terrace fills indicate that the construction of these terrace systems started as early as 5300 ± 300 a, which fits well to the beginning of the occupation phase of Jawa at around 3.500 calBC, thus making them to the oldest examples of its kind in the Middle East

  9. Glacial loess or shoreface sands: a re-interpretation of the Upper Ordovician (Ashgillian) glacial Ammar Formation, Southern Jordan

    2003-04-01

    Upper Ordovician (Ashgillian) glacial deposits of the Ammar Formation, Southern Jordan, comprise locally deformed, structureless fine sandstone, incised by glacial channels filled by braided outwash plain sandstones and transgressive marine mudstones. The structureless sandstones, previously interpreted as a glacial rock flour or loessite derived from the underlying undisturbed sandstones, differ significantly from typical loessite and contain hitherto unrecognised sedimentary structures, including hummocky cross-stratification. The sandstones, which grade laterally and vertically into stratigraphically equivalent undeformed marginal marine sandstones, are interpreted as a deformed facies of the underlying sandstones, deposited in a similar high energy shoreface environment. Although deformation of the shoreface sandstones was post-depositional, the origin of the deformation, and its confinement to the Jebel Ammar area is unknown. Deformation due to the weight of the overlying ice is unlikely as the glaciofluvial channels are now thought to have been cut by tunnel valley activity not ice. A more likely mechanism is post-glacial crustal tectonics. Melting of ice caps is commonly associated with intraplate seismicity and the development of an extensional crustal stress regime around the perimeter of ice caps; the interior is largely aseismic because the weight of the ice supresses seismic activity and faulting. Since southern Jordan lay close to the ice cap in Saudi Arabia it may have been subjected to postglacial seismicity and crustal stress, which induced ground shaking, reduced overburden pressure, increased hydrostatic pressure and possibly reactivation of existing tectonic faults. This resulted in liquefaction and extensive deformation of the sediments, which show many characteristics of seismites, generated by earthquake shocks. Since the glaciation was a very short-lived event (0.2-1 Ma), deglaciation and associated tectonism triggering deformation, lasted

    Full Text Available Karst terrains that develop in bodies of rock salt (taken as mainly of halite, NaCl are special not only for developing in one of the most soluble of all rocks, but also for developing in one of the weakest rocks. Salt is so weak that many surface-piercing salt diapirs extrude slow fountains of salt that that gravity spread downslope over deserts on land and over sea floors. Salt fountains in the deserts of Iran are usually so dry that they flow at only a few cm/yr but the few rain storms a decade so soak and weaken them that they surge at dm/day for a few days. We illustrate the only case where the rates at which different parts of one of the many tens of subaerial salt karst terrains in Iran flows downslope constrains the rates at which its subaerial salt karst terrains form. Normal seawater is only 10% saturated in NaCl. It should therefore be sufficiently aggressive to erode karst terrains into exposures of salt on the thousands of known submarine salt extrusions that have flowed or are still flowing over the floors of hundreds of submarine basins worldwide. However, we know of no attempt to constrain the processes that form submarine salt karst terrains on any of these of submarine salt extrusions. As on land, many potential submarine karst terrains are cloaked by clastic and pelagic sediments that are often hundreds of m thick. Nevertheless, detailed geophysical and bathymetric surveys have already mapped likely submarine salt karst terrains in at least the Gulf of Mexico, and the Red Sea. New images of these two areas are offered as clear evidence of submarine salt dissolution due to sinking or rising aggressive fluids. We suggest that repeated 3D surveys of distinctive features (± fixed seismic reflectors of such terrains could measure any downslope salt flow and thus offer an exceptional opportunity to constrain the rates at which submarine salt karst terrains develop. Such rates are of interest to all salt tectonicians and the many

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

    Salameh, Elias

    The recharge sources, the flow mechanisms and discharge areas of the different groundwater bodies underlying the Yarmouk River catchment area in Jordan, have, until now, not been adequately explained, although a wide range of hydrological, hydrogeological, and hydrochemical studies have been done. Along the Jordanian part of the catchment area of the Yarmouk River, groundwater issues from different aquifers with a variety of chemistries and types within the same aquifer and in between the different aquifers. Conventional recharge/discharge mechanisms, water balances and chemical analyses did not adequately explain the chemical variations and the different water types found in the area. Applying environmental isotopic tools combined with their altitude effects due to topographic variations (250-1,300 m a.s.l. within a distance of 20 km), and taking into consideration re-evaporation effects on the isotopic depletion and enrichment of rainwater, has greatly helped in understanding the recharge discharge mechanisms of the different aquifers. Precipitation along the highlands of an average of 600 mm/year is found to be depleted in its isotopic content of δO18 = -7.0 to -7.26 and δD = -32.2 to -33.28, whereas that of the Jordan Valley of 350 mm/year is highly enriched in isotopes with δO18 = -4.06 and δD = -14.5. The groundwater recharged along the highlands is depleted in isotopes (δO18 = -6, δD = -30), groundwater at the intermediate elevations is enriched (δO18 = -5, δD = -23) and that of the Jordan Valley aquifers containing meteoric water is highly enriched (δO18 -3.8, δD = -18). The deep aquifers in the Jordan Valley foothills are depleted in isotopes (δO18 -18 = -6, δD = -30) and resemble those of the highland aquifers. Only through using isotopes as a tool, were the sources of the different groundwater bodies and recharge and discharge mechanisms unambiguously explained. It was found that recharge takes place all over the study area and produces

    The medical history of salt begins in ancient times and is closely related to different aspects of human history. Salt may be extracted from sea water, mineral deposits, surface encrustations, saline lakes and brine springs. In many inland areas, wood was used as a fuel source for evaporation of brine and this practice led to major deafforestation in central Europe. Salt played a central role in the economies of many regions, and is often reflected in place names. Salt was also used as a basis for population censuses and taxation, and salt monopolies were practised in many states. Salt was sometimes implicated in the outbreak of conflict, e.g. the French Revolution and the Indian War of Independence. Salt has also been invested with many cultural and religious meanings, from the ancient Egyptians to the Middle Ages. Man's innate appetite for salt may be related to his evolution from predominantly vegetarian anthropoids, and it is noteworthy that those people who live mainly on protein and milk or who drink salty water do not generally salt their food, whereas those who live mainly on vegetables, rice and cereals use much more salt. Medicinal use tended to emphasize the positive aspects of salt, e.g. prevention of putrefaction, reduction of tissue swelling, treatment of diarrhea. Evidence was also available to ancient peoples of its relationship to fertility, particularly in domestic animals. The history of salt thus represents a unique example for studying the impact of a widely used dietary substance on different important aspects of man's life, including medical philosophy.

    The idea that all underground salt deposits can serve as storage sites for toxic and nuclear waste does not always hold water—literally. According to Daniel Ronen and Brian Berkowitz of Israel's Weizmann Institute of Science and Yoseph Yechieli of the Geological Survey of Israel, some buried salt layers are in fact highly conductive of liquids, suggesting that wastes buried in their confines could easily leech into groundwater and nearby soil.When drilling three wells into a 10,000-year-old salt layer near the Dead Sea, the researchers found that groundwater had seeped into the layer and had absorbed some of its salt.

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

    2010-05-01

    Developing new water resources continues to be a challenge in water scarce regions and water reuse offers a sustainable means by which water availability can be maximised. In Jordan, treated domestic wastewater (reclaimed water) already provides a valuable contribution to the annual water budget. This resource is used for irrigation either directly around wastewater treatment plants, or indirectly after reclaimed water released from treatment plants has been transferred though natural waterways and blended with surface runoff. Direct reuse is employed for the irrigation of fodder crops such as barley or alfalfa, while indirect reuse is employed for the irrigation of high-value fruit and vegetable crops grown in the Jordan Valley, a major commercial agricultural area. In order to ensure water reuse is conducted successfully, it is essential that the benefits of reclaimed water (water availability, high nutrient content) are maximised while the potential risks (to human health, soil sustainability and agricultural yields) are minimised. Stakeholder participation in water reuse management decisions could raise the capacity of the water user (such as the farmer) to manage the risks without compromising the benefits of this resource. To investigate the extent to which stakeholders are participating in water reuse management, semi-structured interviews with farmers and institutional representatives were conducted in Jordan. A particular aim of the interviews was to explore the variation in participation between those stakeholders using reclaimed water directly and indirectly. The data collected during 56 interviews with Jordanian farmers showed that the farmers' perception and management of reclaimed water varied considerably between the indirect and direct users. The direct users had a greater level of satisfaction with the water (55 per cent of those asked described the water as "good water") and recognised that they were able to produce larger yields and raise their

    Utility-scale solar energy (USSE, ≥ 1 megawatt [MW]) systems are rapidly being deployed in the Central Valley of California, generating clean electricity and new job opportunities. Utility-scale solar energy systems require substantial quantities of land or space, often prompting an evaluation of environmental impacts and trade-offs when selecting their placement. Utilizing salt-contaminated agricultural land (as the sodium absorption and electrical conductivity values are unsuitably high), unsuitable for food production, and lands within the built environment (developed), can serve as a co-benefit opportunity when reclamation of these lands for USSE development is prioritized. In this study, we quantify the theoretical and generation-based solar energy potential for the Central Valley according to land-cover type, crop type, and for salt-contaminated lands. Further, we utilize the Carnegie Energy and Environmental Compatibility (CEEC) model to identify and prioritize solar energy, integrating environmental resource opportunities and constraints most relevant to the Central Valley. We use the CEEC model to generate a value-based environmental compatibility output for the Central Valley. The Central Valley extends across nearly 60,000 km2 of California with the potential of generating 21,800 - 30,300 TWh y-1 and 41,600 TWh y-1 of solar energy for photovoltaic (PV) and concentrating solar power (CSP), respectively. Pasture, hay, and cultivated crops comprise over half of the Central Valley, much of which is considered prime agriculture or of statewide or local importance for farming (28,200 km2). Together, approximately one-third of this region is salt-contaminated (16%) or developed (11%). This confers a generation-based potential of 5713 - 7891 TWh y-1 and 2770 TWh y-1 for PV and CSP, respectively. As energy, food, and land are inextricably linked, our study shows how land favorable for renewable energy systems can be used more effectively in places where land is

    Violence against nurses in emergency departments (EDs) has become a widespread phenomenon affecting nurses' job satisfaction and work performance. Literature is scarce regarding prevalence rates and causes of violence directed toward nurses in Jordan. The present study investigated violence experienced by Jordanian nurses in EDs and causes of violence from their perspectives. This descriptive study collected data from 174 Jordanian ED nurses. The majority of the participants (91.4%) reported experiencing violence (verbal 95.3% vs. physical 23.3%). According to participants, the most common causes of violence in the ED were crowding and workload (75.9%), and the least was care of patients with dementia or Alzheimer's disease (35.6%). Violence is common in Jordanian EDs, giving rise to many heath and behavioral consequences. Health care administrators are obligated to protect nurses from violent incidents by providing adequate safety measures, beneficial administrative procedures, and sincere efforts to overcome the causes of this phenomenon. © 2015 The Author(s).

  1. Energy demand, poverty and the urban environment in Jordan

    This paper presents some insights into the prime problems of energy and related environmental issues as well as urbanisation in Jordan. The country has very limited natural resources: water is scarce; arable land is limited; and fossil-fuel sources are few. Moreover, the population is increasing rapidly. Hence, problems are arising. During the last 30 years, the country has experienced vast changes in its infrastructure with respect to the housing, urbanisation, commerce, agriculture and industry. Such developments have led to increasing demographic stresses: unemployment has increased and poverty is experienced by more than half of the population. The pressures have resulted in a high percentage of the population moving from rural to urban areas and so society is becoming less self-sufficient. At present, energy consumption in the residential sector accounts for about one quarter of the kingdom's fuel consumption. Kerosene, bottled LPG, diesel fuel and electricity are the main forms of energy used by households, but kerosene is still the dominant fuel because about 83% of households depend on it for space and water heating. The use of open fires and/or portable stoves has led to an increasing number of people being killed each year by suffocation or suffering health problems due to the inhalation of fumes and gaseous pollutants. Thus a national plan to achieve energy thrift and protect the environment, as well as accomplish the more rational utilisation of the limited natural resources available, is urgently needed and should be enacted soon.

The deterioration of water quality due to excess algal biomass in lakes has been well documented (e.g., water clarity, hypoxic conditions, but health risks associated with cyanotoxins remain largely unexplored in the absence of toxin information. This study is the first to document the presence of dissolved microcystin, anatoxin-a, cylindrospermopsin, and β-N-methylamino-l-alanine in Jordan Lake, a major drinking water reservoir in North Carolina. Saxitoxin presence was not confirmed. Multiple toxins were detected at 86% of the tested sites and during 44% of the sampling events between 2014 and 2016. Although concentrations were low, continued exposure of organisms to multiple toxins raises some concerns. A combination of discrete sampling and in-situ tracking (Solid Phase Adsorption Toxin Tracking [SPATT] revealed that microcystin and anatoxin were the most pervasive year-round. Between 2011 and 2016, summer and fall blooms were dominated by the same cyanobacterial genera, all of which are suggested producers of single or multiple cyanotoxins. The study’s findings provide further evidence of the ubiquitous nature of cyanotoxins, and the challenges involved in linking CyanoHAB dynamics to specific environmental forcing factors are discussed.

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

    This study examined the coping strategies used by Syrian refugees in Jordan in relation to their demographics. A cross-sectional correlational study was conducted with a convenient sample of 550 Syrian refugees. Out of all the study participants, 88% reported seeking social support, 64.5% reported using avoidance, and 39.5% reported using problem solving. Participants who were male, single, and younger, and who had a higher education and a higher total income were satisfied with their income, were employed and free of chronic illnesses, and had higher problem-solving scores. Higher social support-seeking scores were associated with being female, older, and widowed; having a lower education and lower total income; being dissatisfied with their income; being nonemployed; and having chronic illnesses. A number of significant predictors were identified for each coping strategy. The results of this study could be used to formulate programs and develop services regarding the stressors encountered by Syrian refugees and their coping strategies.

    To the best of our knowledge, pattern of burn injury was not reported yet at our region, our hospital considered the only tertiary referral center with the only burn unit at the region since 2001 till date, a retrospective analysis of our computerized filing system recorded 527 burn patients between 2001-2016, mean age was 26 years; 1.27:1 was the male to female ratio, 79 patients were found to have major burns, 46% of admissions were below 20 years' age, 92% was at domestic site of affection and 65% due to flame burn followed by scald burn in about 23%. The limbs were the most affected body site, majority of patients were below 15% TBSA and partial thickness, 77 patients found to have inhalational injury. Our mean hospital stay was 16 days and mortality was 8.2%. Mortality was associated with high TBSA affection, depth and flame type. This study shows the pattern of burn at north of Jordan, preventive measures by education and observation will reduce the incidence of burn and its sequel, non-flammable cook plates and stoves will probably help in decrease burn morbidity and mortality.

    Full Text Available Objectives: Depression is acommon mental health disorder. The aim of this study is to determine the level of public awareness regarding this illness, its symptoms, associated factors, available forms of treatment, and the attitude towards depressed people. Methods: A self administered questionnaire was filled in by approximately 5000 individuals selected from various regions of Jordan. Results: The majority of participants thought that depression is a treatable condition that can affect patient at any age, and may be controlled by the will power. Loss of interest in things and presence of negative feelings were the most commonly recognized symptoms of depression, while, unemployment and poverty were found to be the most recognized risk factors for depression. In addition, most participants considered support from family and friends (93.6% as well as exercise (80.4% to be the best available forms of depression treatment. Respondents found it acceptable to work, make friends with, or marry depressed individuals. The first choice persons for seeking help by most participants were family members and friends (49.8%. Conclusion: Collectively, the level of awareness of depression was acceptable. However, further efforts are necessary to establish public educational programs related to depression in order to raise awareness regarding the disease.

  8. Fraud Risk Factors and Audit Programme Modifications: Evidence from Jordan

    Full Text Available This study explores how audit firms in Jordan deal with the presence of fraud risk factors in audit clients. In doing so, the study seeks to explore which fraud risk factors are more important to Jordanianauditors, and how Jordanian auditors consider modifying their audit programmes when fraud risk factors are present in clients. The study uses a structured questionnaire that was administered to seniorlevel auditors in the largest Jordanian audit firms. The findings show that almost all of the 20 fraud risk factors included in the questionnaire were only slightly important (if not unimportant, a finding that is arguably alarming. The perceived importance of modifying the audit programme in the presence of each fraud risk factor was related to the perceived importance of the fraud risk factor itself. However, changes in the nature and extent of audit procedures were more important than changes in the timing of the procedures or the members of the audit team. The most important fraud risk factors were related to the characteristics of management and its attitude towards the audit, while the least important fraud risk factors were related to the difficulties in the client’s financial performance. Factor analysis found that the fraud risk factors could be classified into four separate groups. Possible interpretations of the findings were discussed, such as considering the Jordanian business environment characteristics, and the findings were compared to those of extant international studies.

    Full Text Available The purpose of this paper is to map out the status of English language teaching (ELT as practised in the Arab World and, specifically, in Jordan today. The study also aims to bring into focus significant issues that need to be addressed in ELT in the Arab World. This paper presents a review of the current status of English language education, with an emphasis on the need for urgent reforms in the teaching of English in the Arab World. Further, longitudinal data in respect to classroom and workplace English proficiency are presented. English language education seems to be up-to-date teacher-centred and bound to other issues such as teaching the textbook rather than focusing on developing lifelong strategies. There is a critical need for writing national standards for English language professional development programmes that should be based on the findings of sound research. The paper highlights the significance of teaching English language through observing and reviewing the current practices.

    The aim of this study was to estimate the birth weight distribution and prevalence of low birth weights (LBW) in Irbid, Jordan, and to determine some of the contributing risk factors. A cross-sectional design was used to study women who delivered in Prince Rashed Hospital (PRH). Respondents were 2256 mothers ranging in age from 15-45 years. Anthropometric measurements and interviews were used to determine the risk factors. The birth weights and anthropometric measurements of all babies born alive in PRH during the period were collected. Post-delivery weight and other measurements of respondents were also collected. The mean birth weight of the newborns in the study was 2812 g. Twenty-two percent of the newborns weighed between 700 and 2499 g. About 39% of respondents had urinary tract infection while 29% suffered from anemia, and 10% had bleeding during pregnancy. All anthropometric measurements were significantly associated with LBW. Mothers who were younger in age at their first delivery, had low post-delivery weight, and bled during pregnancy, were more likely to have LBW babies. There is also a need to discourage early pregnancies and to encourage utilization of mother and child health services, and treat concomitant illnesses during pregnancy. (author)

    We are facing a significant challenge in Jordan's Badia region. Such challenge present us given that it will be environmentally protected with easy access to the refrigeration process to food and medical vaccines keeping at a reasonably and economical low cost. Solar cooling method that is generated from the sun as a substitute for batteries or electrical power is characteristic of its kind to store a power system for continued use. A pilot project of solar refrigerator was tested to collect technological data on a standard basis so the method control tests are accurate and precise. Solar refrigerator does not require electricity, which utilizes a combination of heat conduction and convection. In addition, it can be made from readily available material such as cardboard, sand, and recycled metal. It is constructed from two cylinders: an inner metal cylinder, fitted inside, and an outer cylinder that can be made of wood or plastic, etc, and organic material such as (sand, wool, or soil) placed in the left space between the two cylinders which is then saturated with water. As heat from the sun evaporates the water, the inner chamber is cooled to reduce and maintains the temperature at (6 degree C). (authors)

    The goal of this study was to assess the effect of dark chocolate intake on cardiovascular parameters like blood pressure and heart rate values in a normotensive population. This is a randomized cross-sectional study involving a total of 14,310 adults that were selected from various regions of Jordan. Well-trained pharmacy students interviewed participants in the outpatient settings. Participants reported their weekly intake of dark chocolate that has been further classified into mild (1-2 bars/week), moderate (3-4 bars/week), and high intake ( > 4 bars/week). For each participant, the systolic blood pressure (SBP), diastolic blood pressure (DBP), and heart rate were measured three times with (10-15) minute intervals in the sitting position and the resting state. The arterial blood pressure (ABP) was calculated from the measured SBP and DBP values. All measured blood pressure values were significantly decreased for participants who reported higher dark chocolate consumption. Our results showed that heart rate values were not affected by variable intake of dark chocolate. In addition, increasing dark chocolate intake was associated with a significant decrease of blood pressure values in participants irrespective of the family history of hypertension or the age of the individual. However, heart rate values were unaffected. Higher intake of dark chocolate can be associated with lower values of blood pressure, while its effect on heart rate values was not consistent.

    Soybean is an Important cash crop and its productivity is significantly hampered by salt stress. High salt Imposes negative impacts on growth, nodulation, agronomy traits, seed quality and quantity, and thus reduces the yield of soybean. To cope with salt stress, soybean has developed several tolerance mechanisms, including: (I) maintenance of ion homeostasis; (ii) adjustment in response to osmotic stress; (iii) restoration of osmotic balance; and (iv) other metabolic and structural adaptations. The regulatory network for abiotic stress responses in higher plants has been studied extensively in model plants such as Arabidopsis thaliana. Some homologous components involved in salt stress responses have been identified in soybean. In this review, we tried to integrate the relevant works on soybean and proposes a working model to descdbe Its salt stress responses at the molecular level.

The concept of a transition strength between the elastic and the plastic states is in agreement with the data. The elastic and rheological properties of salt are described, and a set of constitutive equations is presented. The dependence of material properties on parameters such as temperature is considered. Findings on the permeability of salt are summarized, and the in-situ behavior of openings in bedded salt is described based on extensive engineering experience. A stress measuring system utilizing a finite element computer code is discussed. Geological factors affecting the stability of salt openings are considered, and the Stress Control Technique for designing stable openings in bedded salt formations is explained

Jordan appreciates the state’s existing family political measures as well as initiatives that aim at expanding the range of career choices of women and men. Furthermore, Jordan suggests general minimum wages and female quotas for union managerial positions. However, the author rejects a legal verifiability of the principle of equal pay for equal work since the value of work cannot be determined objectively.

    Alkaptonuria (AKU) is one of the four initially identified inborn errors of metabolism. The prevalence of AKU is unknown in Jordan. Therefore, a research project was started in April 2009 at the Faculty of Medicine/Mutah University in southern Jordan. The aims of the project were to identify people with AKU, to screen all family members with history of AKU, and to increase the awareness about the disease among health care professionals and the community in southern Jordan. Targeted family screening method was used to identify patients with AKU. In this paper, we present preliminary results of screening 17 families with history of AKU in a single village in southern region of Jordan. Forty cases with AKU were identified in this village (age range, 1-60 years). Early cases with AKU were diagnosed through out this study, two-third of patients (n = 28) were under the age of thirty. Interestingly, nine cases with AKU were identified in one family. Our experience suggests that for the identification of cases with AKU where consanguinity is common, the focus for screening should be extended to all family members. The prevalence of AKU among Jordanian is likely to be greater than the prevalence rates worldwide due to high rates of consanguineous marriages. Further studies and effective screening programs are needed to detect undiagnosed cases of AKU, to provide genetic counseling, and ultimately to prevent the occurrence of new cases of AKU in Jordan.

    Antimicrobial resistance is a serious global health concern. It has considerable implications on societies' health and resources. In Jordan, there is a large Iraqi community due to the ongoing turmoil in Iraq. Unfortunately, health awareness and practices of this community are under-investigated due to scarcity of research. This paper assesses the awareness of antibiotic use and antimicrobial resistance in the Iraqi community residing in Amman, Jordan. Their level of interaction with health care professionals regarding antibiotics and differences in their antibiotic use between Iraq and Jordan are also discussed. A cross-sectional questionnaire-based survey involving randomly selected Iraqis residing in Amman, Jordan was conducted. The study involved 508 participants. Sixty-two percent of participants agreed with buying antibiotics without a prescription, 29% agreed with obtaining antibiotics from friends or relatives, and 46% agreed with keeping leftover antibiotics for future use. Furthermore, 60% disagreed with not completing an antibiotic course and almost 90% of the sample listed viral diseases as an indication for antibiotics. Forty-four percent of participants abided by physicians' instructions on antibiotic use. Half of the participants believed that pharmacists provided instructions on antibiotics all the time, whereas physicians were perceived to do so by 29% of participants. Gaps exist in knowledge of antibiotic use and reasons for antimicrobial resistance among Iraqis residing in Jordan. These gaps should serve in planning educational campaigns to raise the community's awareness of responsible antibiotic use. Law enforcement to restrict access to antibiotics is also pivotal to tackle their misuse.

  7. Crushed Salt Constitutive Model

    International Nuclear Information System (INIS)

    Callahan, G.D.

    1999-01-01

    The constitutive model used to describe the deformation of crushed salt is presented in this report. Two mechanisms -- dislocation creep and grain boundary diffusional pressure solution -- are combined to form the basis for the constitutive model governing the deformation of crushed salt. The constitutive model is generalized to represent three-dimensional states of stress. Upon complete consolidation, the crushed-salt model reproduces the Multimechanism Deformation (M-D) model typically used for the Waste Isolation Pilot Plant (WIPP) host geological formation salt. New shear consolidation tests are combined with an existing database that includes hydrostatic consolidation and shear consolidation tests conducted on WIPP and southeastern New Mexico salt. Nonlinear least-squares model fitting to the database produced two sets of material parameter values for the model -- one for the shear consolidation tests and one for a combination of the shear and hydrostatic consolidation tests. Using the parameter values determined from the fitted database, the constitutive model is validated against constant strain-rate tests. Shaft seal problems are analyzed to demonstrate model-predicted consolidation of the shaft seal crushed-salt component. Based on the fitting statistics, the ability of the model to predict the test data, and the ability of the model to predict load paths and test data outside of the fitted database, the model appears to capture the creep consolidation behavior of crushed salt reasonably well

    Molten salt reactors are one of the 6 concepts retained for the 4. generation of nuclear reactors. The principle of this reactor is very innovative: the nuclear fuel is dissolved in the coolant which allows the online reprocessing of the fuel and the online recovery of the fission products. A small prototype: the Molten Salt Reactor Experiment (MSRE - 8 MWt) was operating a few years in the sixties in the USA. The passage towards a fast reactor by the suppression of the graphite moderator leads to the concept of Molten Salt Fast Reactor (MSFR) which is presently studied through different European projects such as MOST, ALISIA and EVOL. Worldwide the main topics of research are: the adequate materials resisting to the high level of corrosiveness of the molten salts, fuel salt reprocessing, the 3-side coupling between neutron transport, thermohydraulics and thermo-chemistry, the management of the changing chemical composition of the salt, the enrichment of lithium with Li 7 in the case of the use of lithium fluoride salt and the use of MSFR using U 233 fuel (thorium cycle). The last part of the article presents a preliminary safety analysis of the MSFR. (A.C.)

    A proposal for the exploration of geothermal energy in Jordan for heating greenhouses. The report gives some background information on geothermal anomalies in Jordan, and outlines some on-going uses of geothermal energy in various parts of Jordan. The proposal is modelled on the 2664 square meter Filclair Super 9 Multispan greenhouse from France. The overall cost of the project involves three variables, the cost of the borehole, the cost of the greenhouse, and the cost of engineering services. The total cost ranges between three to four million dollars depending on the quantity and quality of information to be collected from the borehole. The advantages of geothermal heating compared with oil heating are emphasized. The project will enable geothermal heating and horticultural production to be monitored throughout the year, will produce data enabling rational and reliable water resources management, and will produce environmentally clean and efficient energy.

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

Interactive teaching methods showed positive results in enhancing health awareness and adopting healthy practices among students. Objectives: The objective of this study was to examine the usefulness of interactive teaching in promoting health awareness of RH among nonmedical university students in Jordan.Methods: We employed a quasi-experimental one group pretest and posttest design for a purposive sample of 210 students (18–24 years. Knowledge and attitudes regarding RH issues were assessed using a questionnaire developed by the researchers. Results: A significant improvement in students’ knowledge and attitudes toward RH was evident. Female students had higher scores on knowledge than male students in the pretest; this difference was smaller in the posttest. Also, female students had significantly more positive attitudes toward RH in pretest than males, although this difference vanished in the posttest. Study results indicated that students benefit from study intervention regardless their gender. Conclusion: Integrating RH into university’s curriculum coupled with interactive learning approach is a powerful way to promote RH awareness among youths.

    2008-01-01

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

  15. Mapping of networks to detect priority zoonoses in Jordan

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

    Exploring the perspective of parents on the cochlear implant process in Jordan. Sixty parents of deaf children were surveyed on the information gathering process prior to cochlear implant surgery, and their implant outcome expectations post-surgery. Whether child or parent characteristics may impact parents' post-surgical expectations was explored. Although parents used a variety of information sources when considering a cochlear implant, the ear, nose and throat doctor comprised their major source of information (60%). Parents received a range of information prior to cochlear implant but agreed (93.3%) on the need for a multidisciplinary team approach. Post-surgically, parents' expected major developments in the areas of spoken language (97%), and auditory skills (100%). Receiving education in mainstream schools (92%) was expected too. Parents perceived the cochlear implant decision as the best decision they can make for their child (98.3%). A significant correlation was found between parents contentment with the cochlear implant decision and expecting developments in the area of reading and writing (r=0.7). Child's age at implantation and age at hearing loss diagnosis significantly affected parents' post-implant outcome expectations (pparents agree on the need for a comprehensive multidisciplinary team approach during the different stages of the cochlear implant process. Parents' education about cochlear implants prior to the surgery can affect their post-surgical outcome expectations. The parental perspective presented in this study can help professionals develop better understanding of parents' needs and expectations and henceforth improve their services and support during the different stages of the cochlear implant process.

    Purpose The influx of Syrian refugees into Jordan and Lebanon over the last 5 years presents an immense burden to national health systems. This study was undertaken to assess utilization of maternal health services among Syrian refugees in both countries. Description A cross-sectional survey of Syrian refugees living in urban and rural (non-camp) settings was conducted using a two-stage cluster survey design with probability proportional to size sampling in 2014-2015. Eighty-six percent of surveyed households in Lebanon and 88% of surveyed households in Jordan included women with a live birth in the last year. Information from women in this sub-set of households was analyzed to understand antenatal and intrapartum health service utilization. Assessment A majority of respondents reported seeking antenatal care, 82% and 89% in Jordan and Lebanon, respectively. Women had an average of at least six antenatal care visits. Nearly all births (98% in Jordan and 94% in Lebanon) took place in a health facility. Cesarean rates were similar in both countries; approximately one-third of all births were cesarean deliveries. A substantial proportion of women incurred costs for intrapartum care; 33% of Syrian women in Jordan and 94% of Syrian women in Lebanon reported paying out of pocket for their deliveries. The proportion of women incurring costs for intrapartum care was higher in Jordan both countries for women with cesarean deliveries compared to those with vaginal deliveries; however, this difference was not statistically significant in either country (Jordan p-value = 0.203; Lebanon p-value = 0.099). Conclusion Syrian refugees living in Jordan and Lebanon had similar levels of utilization of maternal health services, despite different health systems and humanitarian assistance provisions. As expected, a substantial proportion of households incurred out-of-pocket costs for essential maternal and newborn health services, making cost a major factor in care

    Sridhar, B.; Jordan, D.

    1974-01-01

    This paper investigates various aspects of the application of the Jordan canonical form of a matrix in system theory and develops a computational approach to determining the Jordan form for a given matrix. Applications include pole placement, controllability and observability studies, serving as an intermediate step in yielding other canonical forms, and theorem proving. The computational method developed in this paper is both simple and efficient. The method is based on the definition of a generalized eigenvector and a natural extension of Gauss elimination techniques. Examples are included for demonstration purposes.

    2018-06-01

    The present work shows that the mathematical equivalence of the Jordan frame and its conformally transformed version, the Einstein frame, so as far as Brans-Dicke theory is concerned, survives a quantization of cosmological models, arising as solutions to the Brans-Dicke theory. We work with the Wheeler-deWitt quantization scheme and take up quite a few anisotropic cosmological models as examples. We effectively show that the transformation from the Jordan to the Einstein frame is a canonical one and hence two frames furnish equivalent description of same physical scenario.

    Sridhar, B.; Jordan, D.

    1973-01-01

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

    Salt is the proposed host rock for geologic repositories of nuclear waste in several nations because it is nearly dry and probably impermeable. Although experiments and experience at potential salt sites indicate that salt may contain brine, the low porosity, creep, and permeability of salt make it still a good choice for geologic isolation. In this paper we summarize several mass-transfer and transport analyses of salt repositories. The mathematical details are given in our technical reports

    This document is one of the three parts of a first volume devoted to the compilations of American data on the molten salt reactor concept. Emphasize is put essentially on the fuel salt of the primary circuit inside which fission reactions occur. The reasons why the (LiF-BeF 2 -ThF 4 -UF 4 ) salt was chosen for the M.S.B.R. concept are examined; the physical, physicochemical and chemical properties of this salt are discussed with its interactions with the structural materials and its evolution in time. An important part of this volume is devoted to the continuous reprocessing of the active salt, the project designers having deemed advisable to take advantage at best from the availability of a continuous purification, in a thermal breeding. The problem of tritium formation and distribution inside the reactor is also envisaged and the fundamentals of the chemistry of the secondary coolant salt are given. The solutions proposed are: the hydrogen scavenging of the primary circuit, a reduction in metal permeability by an oxyde layer deposition on the side in contact with the vapor, and tritium absorption through an isotope exchange with the hydroxifluoroborate [fr

Detailed analysis of the net energetics of complex salt bridge formation using double- and triple-mutant cycle analysis revealed conflicting results. In two cases, it was shown that complex salt bridge formation is cooperative, i.e., the net strength of the complex salt bridge...

  11. Pascual Jordan, his contributions to quantum mechanics and his legacy in contemporary local quantum physics

    International Nuclear Information System (INIS)

    Schroer, Bert; Freie Universitaet, Berlin

    2003-05-01

    After recalling episodes from Pascual Jordan's biography including his pivotal role in the shaping of quantum field theory and his much criticized conduct during the NS regime, I draw attention to his presentation of the first phase of development of quantum field theory in a talk presented at the 1929 Kharkov conference. He starts by giving a comprehensive account of the beginnings of quantum theory, emphasising that particle-like properties arise as a consequence of treating wave-motions quantum-mechanically. He then goes on to his recent discovery of quantization of 'wave fields' and problems of gauge invariance. The most surprising aspect of Jordan's presentation is however his strong belief that his field quantization is a transitory not yet optimal formulation of the principles underlying causal, local quantum physics. The expectation of a future more radical change coming from the main architect of field quantization already shortly after his discovery is certainly quite startling. I try to answer the question to what extent Jordan's 1929 expectations have been vindicated. The larger part of the present essay consists in arguing that Jordan's plea for a formulation without 'classical correspondence crutches', i.e. for an intrinsic approach (which avoids classical fields altogether), is successfully addressed in past and recent publications on local quantum physics.

    Full Text Available Objectives. To determine the incidence of cervical cancer in Jordan and assess its trend in over a 14-year period (2000–2013. Methods. This descriptive study was based on secondary analysis of cervical cancer data that are registered in the Jordan Cancer Registry (JCR. Results. A total of 591 women were diagnosed with cervical cancer in Jordan during the period 2000–2013. The age at diagnosis ranged between 15 and 97 years, with a median of 50 years. The average age standardized rate (ASR was 2.0/100,000 women. The incidence of cervical cancer started to decrease after 2006 but it remained relatively constant between 2008 and 2013. Over the 14-year period, ASR for cervical cancer decreased by 28.6% from 2.1 per 100,000 women in 2000 to 1.5 per 100,000 women in 2013. About 46.5% of the cases were of squamous cell carcinoma morphology. Early cancer constituted about 60% of the cases, regional cases constituted 9.6%, and distant metastatic cases constituted 10.7%. Conclusions. The incidence of cervical cancer in Jordan is low compared to regional estimates and remained relatively constant between 2008 and 2013. Implementation of screening measures could lead to better case finding, early diagnosis, and prevention of cervical cancer.

  6. Optimal Conformal Polynomial Projections for Croatia According to the Airy/Jordan Criterion

    Directory of Open Access Journals (Sweden)

    Dražen Tutić

    2009-05-01

    Full Text Available The paper describes optimal conformal polynomial projections for Croatia according to the Airy/Jordan criterion. A brief introduction of history and theory of conformal mapping is followed by descriptions of conformal polynomial projections and their current application. The paper considers polynomials of degrees 1 to 10. Since there are conditions in which the 1st degree polynomial becomes the famous Mercator projection, it was not considered specifically for Croatian territory. The area of Croatia was defined as a union of national territory and the continental shelf. Area definition data were taken from the Euro Global Map 1:1 000 000 for Croatia, as well as from two maritime delimitation treaties. Such an irregular area was approximated with a regular grid consisting of 11 934 ellipsoidal trapezoids 2' large. The Airy/Jordan criterion for the optimal projection is defined as minimum of weighted mean of Airy/Jordan measure of distortion in points. The value of the Airy/Jordan criterion is calculated from all 11 934 centres of ellipsoidal trapezoids, while the weights are equal to areas of corresponding ellipsoidal trapezoids. The minimum is obtained by Nelder and Mead’s method, as implemented in the fminsearch function of the MATLAB package. Maps of Croatia representing the distribution of distortions are given for polynomial degrees 2 to 6 and 10. Increasing the polynomial degree results in better projections considering the criterion, and the 6th degree polynomial provides a good ratio of formula complexity and criterion value.

    A water quality trading (WQT) program was promulgated in North Carolina to address water quality issues related to nutrients in the highly urbanizing Jordan Lake Watershed. Although WQT programs are appealing in theory, the concept has not proved feasible in several attempts between point and nonpoint polluters in the United States. Many application hurdles that create wedges between success and failure have been evaluated in the literature. Most programs, however, face multiple hurdles; eliminating one may not clear a pathway to success. Therefore, we identify and evaluate the combined impact of four different wedges including baseline, transaction cost, trading ratio, and trading cost in the Jordan Lake Watershed program. Unfortunately, when applied to the Jordan Lake program, the analysis clearly shows that a traditional WQT program will not be feasible or address nutrient management needs in a meaningful way. The hurdles individually would be difficult to overcome, but together they appear to be unsurmountable. This analysis shows that there is enough information to pre-identify potential hurdles that could inform policy makers where, and how, the concept might work. It would have saved time, energy, and financial resources if North Carolina had done so before embarking to implement their program in the Jordan Lake Watershed. Copyright © 2017 Elsevier Ltd.

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

    International Nuclear Information System (INIS)

    Hamhalter, Jan

    2012-01-01

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

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

    First Nations children experience service delays, disruptions and denials due to jurisdictional payment disputes within and between federal and provincial/territorial governments. The House of Commons sought to ensure First Nations children could access government services on the same terms as other children when it unanimously passed a private members motion in support of Jordan's Principle in 2007. Jordan's Principle states that when a jurisdictional dispute arises regarding public services for a First Nations child that are otherwise available to other children, the government of first contact pays for the service and addresses payment disputes later. Unfortunately, the federal government adopted a definition of Jordan's Principle that was so narrow (complex medical needs with multiple service providers) that no child ever qualified. This narrow definition has been found to be unlawful by the Federal Court of Canada and the Canadian Human Rights Tribunal. The present commentary describes Jordan's Principle, the legal cases that have considered it and the implications of those decisions for health care providers.

    Full Text Available This paper examines the impact of corporate governance quality and board gender diversity on the corporate dividend policy for a set of all non-financial companies listed on Amman Stock Exchange (ASE during the period 2009-2015. The results documented that corporate governance quality and board gender diversity proxies have positive impact on corporate dividend policy. The results also showed that the women representation on the boards of non-financial companies in Jordan is considered low relative to other countries. Particularly, the causes of the poor board gender diversity in Jordan range from lack of awareness about the benefits of gender diversity to the lack of legislation that regulates this issue. It is recommended to non-financial companies in Jordan to boost their compliance with the corporate governance code and adopt diversity policies to enhance the effectiveness of the boards and keep favorable relationships with their shareholders. Furthermore, regulatory bodies in Jordan should take a step towards encouraging gender diversity on boards.

    This 3-D perspective view looking north over Death Valley, California, was produced by draping ASTER nighttime thermal infrared data over topographic data from the US Geological Survey. The ASTER data were acquired April 7, 2000 with the multi-spectral thermal infrared channels, and cover an area of 60 by 80 km (37 by 50 miles). Bands 13, 12, and 10 are displayed in red, green and blue respectively. The data have been computer enhanced to exaggerate the color variations that highlight differences in types of surface materials. Salt deposits on the floor of Death Valley appear in shades of yellow, green, purple, and pink, indicating presence of carbonate, sulfate, and chloride minerals. The Panamint Mtns. to the west, and the Black Mtns. to the east, are made up of sedimentary limestones, sandstones, shales, and metamorphic rocks. The bright red areas are dominated by the mineral quartz, such as is found in sandstones; green areas are limestones. In the lower center part of the image is Badwater, the lowest point in North America.Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) is one of five Earth-observing instruments launched December 18, 1999, on NASA's Terra satellite. The instrument was built by Japan's Ministry of International Trade and Industry. A joint U.S./Japan science team is responsible for validation and calibration of the instrument and the data products. Dr. Anne Kahle at NASA's Jet Propulsion Laboratory, Pasadena, Calif., is the U.S. Science team leader; Moshe Pniel of JPL is the project manager.

    2012-11-01

    Thermal properties of molten salt systems are of interest to electrorefining operations, pertaining to both the Fuel Cycle Research & Development Program (FCR&D) and Spent Fuel Treatment Mission, currently being pursued by the Department of Energy (DOE). The phase stability of molten salts in an electrorefiner may be adversely impacted by the build-up of fission products in the electrolyte. Potential situations that need to be avoided, during electrorefining operations, include (i) fissile elements build up in the salt that might approach the criticality limits specified for the vessel, (ii) electrolyte freezing at the operating temperature of the electrorefiner due to changes in the liquidus temperature, and (iii) phase separation (non-homogenous solution). The stability (and homogeneity) of the phases can be monitored by studying the thermal characteristics of the molten salts as a function of impurity concentration. Simulated salt compositions consisting of the selected rare earth and alkaline earth chlorides, with a eutectic mixture of LiCl-KCl as the carrier electrolyte, were studied to determine the melting points (thermal characteristics) using a Differential Scanning Calorimeter (DSC). The experimental data were used to model the liquidus temperature. On the basis of the this data, it became possible to predict a spent fuel treatment processing scenario under which electrorefining could no longer be performed as a result of increasing liquidus temperatures of the electrolyte.

    The influx of Syrian refugees into Jordan presents an immense burden to the Jordanian health system, particularly in treating chronic health conditions. This study was undertaken to assess utilization of health services for chronic health conditions among Syrian refugees in non-camp settings. A survey of Syrian refugees in Jordan was undertaken in June 2014 to characterize health seeking behaviors and issues related to accessing care for hypertension, diabetes, cardiovascular diseases, chronic respiratory diseases, and arthritis. A cluster design with probability proportional to size sampling was used to attain a nationally representative sample of 1550 non-camp Syrian refugee households. Of 1363 cases with a chronic health condition diagnosis, 84.7% had received care in Jordan. Public facilities faced a heavy burden serving over half (53.9%) of care-seekers; the remainder received care in the private (29.6%) and NGO/charity (16.6%) sectors. Individuals with non-communicable diseases (NCDs) in the central region of Jordan and with arthritis had the lowest rates of care-seeking when compared to other regions and conditions. Overall, 31.6% of care-seekers had an out-of-pocket payment for the most recent care-seeking event which averaged 18.8 USD (median = 0 USD), excluding cost of medications. Forced displacement presents major challenges to those with NCDs, which have the potential to seriously impact both the quality of life and life expectancy amongst refugees. NCD patterns among Syrian refugees indicate the importance of continuing support to public sector services in Jordan to adequately meet expanding needs and ensure appropriate prevention and control of priority NCDs.

    Purpose: To simplify the structure, as well as improve the technical reliability and safety by the elimination of a proton beam entering window. Constitution: The nuclear reactor container main body is made of Hastelloy N and provided at the inner surface with two layers of graphite shields except for openings. An aperture was formed in the upper surface of the container, through which protons accelerated by a linear accelerator are directly entered to the liquid surface of molten salts such as 7LiF-BeF 2 -ThF 4 , 7LiF-NaF-ThF 4 , 7LiF-Rb-UF 4 , NaF-KF-UF 4 and the like. The heated molten salts are introduced by way of a pipeway into a heat exchanger where the heat is transferred to coolant salts and electric generation is conducted by way of heated steams.

    This document is one of the three parts of a first volume devoted to the compilations of American data on the molten salt reactor concept. This part 'CIRCUITS' regroups under a condensed form - in French and using international units - the essential information contained in both basic documents of the American project for a molten-salt breeder power plant. This part is only dealing with things relating to the CEA-EDF workshop 'CIRCUITS'. It is not concerned with information on: the reactor and the moderator replacement, the primary and secondary salts, and the fuel salt reprocessing, that are dealt with in parts 'CORE' and 'CHEMISTRY' respectively. The possible evolutions in the data - and solutions - taken by the American designers for their successive projects (1970 to 1972) are shown. The MSBR power plant comprises three successive heat transfer circuits. The primary circuit (Hastelloy N), radioactive and polluted, containing the fuel salt, includes the reactor, pumps and exchangers. The secondary circuit (pipings made of modified Hastelloy N) contaminated in the exchanger, ensures the separation between the fuel and the fluid operating the turbo-alternator. The water-steam circuit feeds the turbine with steam. This steam is produced in the steam generator flowed by the secondary fluid. Some subsidiary circuits (discharge and storage of the primary and secondary salts, ventilation of the primary circuit ...) complete the three principal circuits which are briefly described. All circuits are enclosed inside the controlled-atmosphere building of the nuclear boiler. This building also ensures the biological protection and the mechanical protection against outer aggressions [fr

    Groundwater over-exploitation has been on the rise in Jordan. Competing demands have grown in the face of perennial water shortages, a situation which has been exacerbated by drought conditions in the past decade. This paper reports findings of a project in which management options to address over-exploitation were developed for one of Jordan's principal aquifer systems, the Amman-Zarqa Basin. Options for addressing the situation were developed through a participatory approach that involved government officials and various public and private sector interest groups. Particular efforts were made to involve well irrigators, who are likely to be heavily impacted by the changes required to reduce groundwater pumping to a sustainable level. With information obtained from a rapid appraisal survey as well as from interviews with farmers, community groups, government officials, and technical experts, an extensive set of options was identified for evaluation. Based on integrated hydrogeologic, social, and economic analysis, five complementary management options were recommended for implementation. These included the establishment of an Irrigation Advisory Service, buying out farm wells, placing firm limits on well ion and irrigated crop areas, exchanging treated wastewater for groundwater, and measures to increase the efficiency of municipal and industrial water use. Various combinations and levels of these options were grouped in scenarios, representing possible implementation strategies. The scenarios were designed to assist decision makers, well owners and other stakeholders in moving gradually towards a sustainable ion regime. Social and economic aspects of each option and scenario were analyzed and presented to stakeholders, together with a of legal, institutional and environmental ramifications. Combining scientific analysis with a participatory approach in the Amman Zarqa Basin groundwater management was devised as a prototype to be used in the management of other

An alternative method has been submitted to the Office of Surface Mining by Virgina. Known as the zoned concept method, it has already been used successfully in building water-holding dams and coal refuse embankments on sloping terrain. The ways in which drainage and seepage are managed are described.

    The study of environmental chloride, deuterium and nitrate has been carried out in sand profiles in two locations in Jordan. The first location is in the Quaternary sediments and sandstones of Al Quwayra in southern Jordan where the average rainfall is less than 70 mm per year. The study concluded that there is no modern recharge in the studied site in southern Jordan. The second location is in the Kurnub sandstone outcrop near to Jarash in northern Jordan. The average rainfall in the area is 500 mm per year and thus significant recharge is possible in that area. The study showed that the annual recharge to the aquifer in that area is about 28 mm per year. The third location consists of four cores is in the alluvium Mudflat deposits of Azraq Oasis. The average rainfall in this area is about 67 mm per year which occur as storms between January and March. (author)

    1980-01-01

    Molten salt reactor is an advanced breeder concept which is suited for the utilization of thorium for nuclear power production. This reactor is based on the use of solutions of uranium or plutonium fluorides in LiF-BeF 2 -ThF 4 as fuel. Unlike the conventional reactors, no external coolant is used in the reactor core and the fuel salt itself is circulated through heat exchangers to transfer the fission produced heat to a secondary salt (NaF-NaBF 4 ) for steam generation. A part of the fuel stream is continuously processed to isolate 233 Pa, so that it can decay to fissile 233 U without getting converted to 234 Pa, and for the removal of neutron absorbing fission products. This on-line processing scheme makes this reactor concept to achieve a breeding ratio of 1.07 which is the highest for any thermal breeder reactor. Experimental studies at the Bhabha Atomic Research Centre, Bombay, have established the use of plutonium as fuel for this reactor. This molten salt reactor concept is described and the work conducted at the Bhabha Atomic Research Centre is summarised. (auth.)

    1994-01-01

    A molten cadmium phase (lower side) and a molten salt phase (upper side) are filled in an electrolytic bath. A basket incorporating spent nuclear fuels is inserted/disposed in the molten cadmium phase. A rotatable solid cathode is inserted/disposed in the molten salt phase. The spent fuels, for example, natural uranium, incorporated in the basket is dissolved in the molten cadmium phase. In this case, the uranium concentration in the molten salt phase is determined as from 0.5 to 20wt%. Then, electrolysis is conducted while setting a stirring power for stirring at least the molten salt phase of from 2.5 x 10 2 to 1 x 10 4 based on a reynolds number. Crystalline nuclei of uranium are precipitated uniformly on the surface of the solid cathode, and they grow into fine dendrites. With such procedures, since short-circuit between the cathode precipitates and the molten cadmium phase (anode) is scarcely caused, to improve the recovering rate of uranium. (I.N.)

  5. Borehole closure in salt

    Constitutive law parameters are determined from salt behavior characterization experiments. The results are applied to predict creep (time-dependent) closure of boreholes in salt specimens subjected to various loading configurations. Rheological models (linear and nonlinear viscoelastic and viscoplastic models), empirical models, and physical theory models have been formulated from the results of uniaxial creep tests, strain and stress rate controlled uniaxial tests, constant strain rate triaxial tests, cyclic loading tests, and seismic velocity measurements. Analytical solutions for a thick-walled cylinder subjected to internal and external pressures and for a circular hole in an infinite plate subjected to a biaxial or uniaxial stressfield have been derived from each of the linear viscoelastic models and from one of the empirical laws. The experimental results indicate that the salt samples behave as an elastic-viscoplastic material. The elastic behavior tends to be linear and time-independent. The plastic deformation is time-dependent. The stress increment to strain rate increment ratio gradually decreases as the stress level increases. The transient potential creep law seems to give the simplest satisfactory governing equation describing the viscoplastic behavior of salt during the transient phase. 204 refs., 27 figs., 29 tabs

    As the socioeconomic conditions in Jordan have improved over recent decades the disease and economic burden of Hepatitis A has increased. The purpose of this study is to assess the potential health and economic impact of a two-dose hepatitis A vaccine program covering one-year old children in Jordan. We adapted an age-structured population model of hepatitis A transmission dynamics to project the epidemiologic and economic impact of vaccinating one-year old children for 50 years in Jordan. The epidemiologic model was calibrated using local data on hepatitis A in Jordan. These data included seroprevalence and incidence data from the Jordan Ministry of Health as well as hospitalization data from King Abdullah University Hospital in Irbid, Jordan. We assumed 90% of all children would be vaccinated with the two-dose regimen by two years of age. The economic evaluation adopted a societal perspective and measured benefits using the quality-adjusted life-year (QALY). The modeled vaccination program reduced the incidence of hepatitis A in Jordan by 99%, 50 years after its introduction. The model projected 4.26 million avoided hepatitis A infections, 1.42 million outpatient visits, 22,475 hospitalizations, 508 fulminant cases, 95 liver transplants, and 76 deaths over a 50 year time horizon. In addition, we found, over a 50 year time horizon, the vaccination program would gain 37,502 QALYs and save over $42.6 million in total costs. The vaccination program became cost-saving within 6 years of its introduction and was highly cost-effective during the first 5 years. A vaccination program covering one-year old children is projected to be a cost-saving intervention that will significantly reduce the public health and economic burden of hepatitis A in Jordan.

  11. Salt ingestion caves.

    Directory of Open Access Journals (Sweden)

    Lundquist Charles A.

    2006-01-01

    Full Text Available Large vertebrate herbivores, when they find a salt-bearing layer of rock, say in a cliff face, can produce sizable voids where, overgenerations, they have removed and consumed salty rock. The cavities formed by this natural animal process constitute a uniqueclass of caves that can be called salt ingestion caves. Several examples of such caves are described in various publications. Anexample in Mississippi U.S.A., Rock House Cave, was visited by the authors in 2000. It seems to have been formed by deer orbison. Perhaps the most spectacular example is Kitum Cave in Kenya. This cave has been excavated to a length over 100 metersby elephants. An ancient example is La Cueva del Milodon in Chile, which is reported to have been excavated by the now extinctmilodon, a giant ground sloth. Still other possible examples can be cited. This class of caves deserves a careful definition. First, thecavity in rock should meet the size and other conventions of the locally accepted definition of a cave. Of course this requirement differsin detail from country to country, particularly in the matter of size. The intent is to respect the local conventions. The characteristicthat human entry is possible is judged to be a crucial property of any recognized cave definition. Second, the cavity should besignificantly the result of vertebrate animal consumption of salt-bearing rock. The defining process is that rock removed to form thecave is carried away in the digestive track of an animal. While sodium salts are expected to be the norm, other salts for which thereis animal hunger are acceptable. Also some other speleogenesis process, such as solution, should not be excluded as long as it issecondary in formation of a cave in question.

    By the end of the fiscal year, the West Valley Demonstration Project had processed 757,000 litres of liquid high-level waste, removing most of the radioactive constituents by ion exchange. The radioactive ion exchange material is being stored in an underground tank pending its incorporation, along with sludge still in the tank, into borosilicate glass. The decontaminated salt solution was solidified into a cement low-level waste form which has been reviewed and endorsed by the Nuclear Regulatory Commission. Five tests of the waste glass melter system were completed. A Notice of Intent was published to prepare a joint federal/state Environmental Impact Statement. Design of the Vitrification Facility, a major milestone, was completed and construction of the facility enclosure has begun. A Department of Energy Tiger Team and Technical Safety Appraisal of the Project found no undue risks to worker or public health and safety or the environment

    There are currently more people displaced by conflict than at any time since World War II. The profile of displaced populations has evolved with displacement increasingly occurring in urban and middle-income settings. Consequently, an epidemiological shift away from communicable diseases that have historically characterized refugee populations has occurred. The high prevalence of non-communicable diseases (NCDs) poses a challenge to in terms of provision of appropriate secondary and tertiary services, continuity of care, access to medications, and costs. In light of the increasing burden of NCDs faced by refugees, we undertook this study to characterize the prevalence of NCDs and better understand issues related to care-seeking for NCDs among Syrian refugees in non-camp settings in Jordan. A cross-sectional survey of 1550 refugees was conducted using a multi-stage cluster design with probability proportional to size sampling to obtain a nationally representative sample of Syrian refugees outside of camps. To obtain information on chronic conditions, respondents were asked a series of questions about hypertension, cardiovascular disease, diabetes, chronic respiratory disease, and arthritis. Differences by care-seeking for these conditions were examined using chi-square and t-test methods and characteristics of interest were included in the adjusted logistic regression model. Among adults, hypertension prevalence was the highest (9.7%, CI: 8.8-10.6), followed by arthritis (6.8%, CI: 5.9-7.6), diabetes (5.3%, CI: 4.6-6.0), chronic respiratory diseases (3.1%, CI: 2.4-3.8), and cardiovascular disease (3.7%, CI: 3.2, 4.3). Of the 1363 NCD cases, 84.7% (CI: 81.6-87.3) received care in Jordan; of the five NCDs assessed, arthritis cases had the lowest rates of care seeking at 65%, (CI:0-88, p = 0.005). Individuals from households in which the head completed post-secondary and primary education, respectively, had 89% (CI: 22-98) and 88% (CI: 13-98) lower odds of seeking care

    The ordering problem has been one of the long standing and much discussed questions in quantum mechanics from its very beginning. Nowadays, there is more or less a consensus among physicists that the right prescription is Weyl’s rule, which is closely related to the Moyal–Wigner phase space formalism. We propose in this report an alternative approach by replacing Weyl quantization with the less well-known Born–Jordan quantization. This choice is actually natural if we want the Heisenberg and Schrödinger pictures of quantum mechanics to be mathematically equivalent. It turns out that, in addition, Born–Jordan quantization can be recovered from Feynman’s path integral approach provided that one used short-time propagators arising from correct formulas for the short-time action, as observed by Makri and Miller. These observations lead to a slightly different quantum mechanics, exhibiting some unexpected features, and this without affecting the main existing theory; for instance quantizations of physical Hamiltonian functions are the same as in the Weyl correspondence. The differences are in fact of a more subtle nature; for instance, the quantum observables will not correspond in a one-to-one fashion to classical ones, and the dequantization of a Born–Jordan quantum operator is less straightforward than that of the corresponding Weyl operator. The use of Born–Jordan quantization moreover solves the “angular momentum dilemma”, which already puzzled L. Pauling. Born–Jordan quantization has been known for some time (but not fully exploited) by mathematicians working in time–frequency analysis and signal analysis, but ignored by physicists. One of the aims of this report is to collect and synthesize these sporadic discussions, while analyzing the conceptual differences with Weyl quantization, which is also reviewed in detail. Another striking feature is that the Born–Jordan formalism leads to a redefinition of phase space quantum mechanics, where

    Our work focuses on development of a multi-agent, hydroeconomic model for water policy evaluation in Jordan. Jordan ranks among the most water-scarce countries in the world, a situation exacerbated due to a recent influx of refugees escaping the ongoing civil war in neighboring Syria. The modular, multi-agent model is used to evaluate interventions for enhancing Jordan's water security, integrating biophysical modules that simulate natural and engineered phenomena with human modules that represent behavior at multiple levels of decision making. The hydrologic modules are developed using spatially-distributed groundwater and surface water models, which are translated into compact simulators for efficient integration into the multi-agent model. For the multi-agent model, we explicitly account for human agency at multiple levels of decision making, with agents representing riparian, management, supplier, and water user groups. Human agents are implemented as autonomous entities in the model that make decisions in relation to one another and in response to hydrologic and socioeconomic conditions. The integrated model is programmed in Python using Pynsim, a generalizable, open-source object-oriented software framework for modeling network-based water resource systems. The modeling time periods include historical (2006-2014) and future (present-2050) time spans. For the historical runs, the model performance is validated against historical data for several observations that reflect the interacting dynamics of both the hydrologic and human components of the system. A historical counterfactual scenario is also constructed to isolate and identify the impacts of the recent Syrian civil war and refugee crisis on Jordan's water system. For the future period, model runs are conducted to evaluate potential supply, demand, and institutional interventions over a wide range of plausible climate and socioeconomic scenarios. In addition, model sensitivity analysis is conducted

    Salt diapirs can be asymmetric both internally and externally reflecting their evolution history. As such, this asymmetry bear a significant amount of information about the differential loading (± lateral forces) and in turn the salt supply that have shaped the diapir. In two dimensions......, In this study we compare results of analogue and numerical models of diapirs with two natural salt diapris (Klodawa and Gorleben diapirs) to explain their salt supply and asymmetric evolution. In a NW-SE section, the Gorleben salt diapir possesses an asymmetric external geometry represented by a large...... southeastern overhang due to salt extrusion during Middle Cretaceous followed by its burial in Tertiary. This external asymmetry is also reflected in the internal configuration of the diapir which shows different rates of salt flow on the two halves of the structure. The asymmetric external and internal...

  19. Small martian valleys: Pristine and degraded morphology

    International Nuclear Information System (INIS)

    Baker, V.R.; Partridge, J.B.

    1986-01-01

    The equatorial heavily cratered uplands of Mars are dissected by two classes of small valleys that are intimately associated in compound networks. Pristine valleys with steep valley walls preferentially occupy downstream portions of compound basins. Degraded valleys with eroded walls are laterally more extensive and have higher drainage densities than pristine valleys. Morphometric and crater-counting studies indicate that relatively dense drainage networks were emplaced on Mars during the heavy bombardment about 4.0 b.y. ago. Over a period of approximately 10 8 years, these networks were degraded and subsequently invaded by headwardly extending pristine valleys. The pristine valleys locally reactivated the compound networks, probably through sapping processes dependent upon high water tables. Fluvial activity in the heavily cratered uplands generally ceased approximately 3.8--3.9 b.y. ago, coincident with the rapid decline in cratering rates. The relict compound valleys on Mars are morphometrically distinct from most terrestrial drainage systems. The differences might be caused by a Martian valley formation episode characterized by hyperaridity, by inadequate time for network growth, by very permeable rock types, or by a combination of factors

    Alduraidi, Hamza; Waters, Catherine M

    Jordan hosts more Palestinian refugees than any country in the world. Conditions under which people in a community live influence their health-related quality of life (HRQOL). The purpose of this descriptive comparative cross-sectional study was to compare HRQOL of Palestinian refugees in Jordan who live inside camps with those who live outside camps. Participants, recruited from inside the Baqa'a camp (n = 86) and the surrounding Abu Nsair community (n = 91), completed the World Health Organization Quality of Life Brief questionnaire. There were disparities in education and social relations and environment HRQOL related to income and residency, but not gender, among refugees. Refugees living inside camps, particularly if poorer, fared worse than refugees living outside camps. Enhanced programs and policies may be needed to improve HRQOL, education, and socioeconomics for camp refugees. Nursing's perspective on refugee health could make an important contribution to humanitarian efforts and health diplomacy. Copyright © 2017 Elsevier Inc. All rights reserved.

  4. Frantic Waiting: NGO Anti-Politics and "Timepass" for Young Syrian Refugees in Jordan

    2017-12-01

    Full Text Available Drawing on Sukarieh and Tannock's political economy of youth approach, this paper explores how Syrian refugee youth is constituted in protracted displacement in Jordan. It investigates a juvenile population often overlooked in Forced Migration Studies, disenfranchised rural Syrians, who fail to develop practices of youthfulness, yet in exile are subjected to alternative productions of youth by the aid sector. Depoliticized NGO youth programming overlooks Syrians' limited access to the labour market and higher education. While educational trainings aim to produce entrepreneurial and citizen refugees, they ultimately contribute to the creation of timepass and precarious lives. This research is grounded in fourteen months of ethnographic fieldwork with Syrian refugees in a border town in northern Jordan.

    Humanitarian organisations supporting Syrian refugees in Jordan have conducted needs assessments to direct resources appropriately. To present a model of psychosocial concerns reported by Syrian refugees and a peer review of research practices. Academic and grey literature databases, the United Nations Syria Regional Response website, key humanitarian organisation websites and Google were searched for needs assessments with Syrian refugees in Jordan between February 2011 and June 2015. Information directly reporting the views of Syrian refugees regarding psychosocial needs was extracted and a qualitative synthesis was conducted. Respondents reported that psychological distress was exacerbated by both environmental (financial, housing, employment) and psychosocial outcomes (loss of role and social support, inactivity), which are themselves stressors. Need for improvement in research methodology, participatory engagement and ethical reporting was evident. Participatory engagement strategies might help to address identified psychosocial outcomes. More rigorous qualitative methods are required to ensure accuracy of findings. © The Royal College of Psychiatrists 2016.

    Through narrative analysis, this paper explores the changes in acceptance of and response to substance use in Muslim culture by evaluating data collected in qualitative interviews in Jordan in 2013. What is known and unknown about substance use in Muslim culture throughout the Arab world from previous research findings provides a foundation from which to explore new perspectives and compare themes between younger and older generations in Jordan. Trends of social change and behavioral expression influenced by dramatic political and social upheaval in the Arab world in the last 5 years will also be evaluated for the way in which they may be influencing both substance use and its acceptance among young adults in this population. Recommendations for future research and work in this area are also provided based on these findings.

A transect was determined in Ebbin village in Ajlun (32° 22″ N, 35° 49″ E where the bees were collected from blossoms of stone fruit trees. Most of the specimens were identified up to the species level and few specimens were identified up to the genus level only. A total of 1,461 specimens were collected during the study period and 53 bee species were identified and recorded for the first time in Jordan. The collected species represented five families: Apidae, Megachilidae, Halictidae, Andrenidae and Colletidae. The results showed that Apidae and Megachilidae were the largest in terms of diversity, while Halictidae showed the highest abundance.

The task of collecting and interpreting basic data or mineral resources must be done largely by Jordanians, for only in this way will Jordan acquire the technical competence needed to use the information. Few Jordanians have enough training or experience to work independently in these fields now, however, so help from outside technicians would be necessary over an initial training period of several years. But the number of outside technicians should never exceed the number of Jordanian technicians, and for this reason, neither organization could have a staff of more than a few people during the early years of operation.

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

    Jordan has scarce petroleum resources and hence depends to a large extent on imported crude oil, and natural gas to cover its energy needs and to generate electricity in order to cope with the growing demand. The escalating fuel prices associated with the global economic crisis have negative impacts on the economy of Jordan. However, the availability of renewable energy resources (mainly solar, and wind) supported by well-designed and ambitious incentive schemes that runs in parallel with an energy efficiency program, can contribute positively in solving the current problems. This may result in a dramatic reduction in energy bill cost for both short and long terms. Moreover, it shall result in a better and cleaner environment. In this paper an incentive policy is proposed by the Electricity Regulatory Commission (ERC) based on supporting the installation of PV generating units. ERC plays a major role in this effort which aids decision makers to adopt the proper policies in the electricity sector. It is anticipated that the implementation of this proposed policy will result in a win–win situation for both consumers and government, and will lead to increasing the energy security level in general, and electricity security in particular, within Jordan. - Highlights: ► Encourage usage of solar and wind resources in Jordan through proper regulations. ► Investigate the role of parameters controlling the policy to reach a robust policy. ► Design a win–win PV promotion policy for both the consumer and the government. ► Recommend implementation of the policy on potential tariff categories.

    There is substantial evidence that on average, urban children have better health outcomes than rural children. This paper investigates the underlying factors that account for the regional disparities in child malnutrition in three Arab countries, namely; Egypt, Jordan, and Yemen. We use data on a nationally representative sample from the most recent rounds of the Demographic and Health Survey. A Blinder-Oaxaca decomposition analysis is conducted to decompose the rural-urban differences in child nutrition outcomes into two components; one that is explained by regional differences in the level of the determinants (covariate effects), and another component that is explained by differences in the effect of the determinants on the child nutritional status (coefficient effects). Results show that the under-five stunting rates are 20 % in Egypt, 46.5 % in Yemen, and 7.7 % in Jordan. The rural- urban gap in child malnutrition was minor in the case of Egypt (2.3 %) and Jordan (1.5 %), while the regional gap was significant in the case of Yemen (17.7 %). Results of the Blinder-Oaxaca decomposition show that the covariate effect is dominant in the case of Yemen while the coefficients effect dominates in the case of Jordan. Income inequality between urban and rural households explains most of the malnutrition gap. Results were robust to the different decomposition weighting schemes. By identifying the underlying factors behind the rural- urban health disparities, the findings of this paper help in designing effective intervention measures aimed at reducing regional inequalities and improving population health outcomes.

    1992-01-01

    We present the nonsymmetric Kaluza-Klein and Jordan-Thiry theories as interesting propositions of physics in higher dimensions. We consider the five-dimensional (electromagnetic) case. The work is devoted to a five-dimensional unification of the NGT (nonsymmetric theory of gravitation), electromagnetism, and scalar forces in a Jordan-Thiry manner. We find open-quotes interference effectsclose quotes between gravitational and electromagnetic fields which appear to be due to the skew-symmetric part of the metric. Our unification, called the nonsymmetric Jordan-Thiry theory, becomes the classical Jordan-Thiry theory if the skew-symmetric part of the metric is zero. It becomes the classical Kaluza-Klein theory if the scalar field ρ=1 (Kaluza's Ansatz). We also deal with material sources in the nonsymmetric Kaluza-Klein theory for the electromagnetic case. We consider phenomenological sources with a nonzero fermion current, a nonzero electric current, and a nonzero spin density tensor. From the Palatini variational principle we find equations for the gravitational and electromagnetic fields. We also consider the geodetic equations in the theory and the equation of motion for charged test particles. We consider some numerical predictions of the nonsymmetric Kaluza-Klein theory with nonzero (and with zero) material sources. We prove that they do not contradict any experimental data for the solar system and on the surface of a neutron star. We deal also with spin sources in the nonsymmetric Kaluza-Klein theory. We find an exact, static, spherically symmetric solution in the nonsymmetric Kaluza-Klein theory in the electromagnetic case. This solution has the remarkable property of describing open-quotes mass without massclose quotes and open-quotes charge without charge.close quotes We examine its properties and a physical interpretation. 91 refs., 7 figs

  6. Family ties and economic stability concerns of migrant labour families in Jordan.

    1991-12-01

    74 labor migrant families from various socioeconomic classes in Amman, Jordan were interviewed to examine changes in relationships among family members, extended family, and neighbors and their concerns about economic stability in the host country, Jordan, and the world market. Another purpose was to determine how current migration policies of the Arab oil-producing countries which prohibit labor migrants from bringing their families to the host country affect labor migration among families. The families consisted of either those who did or did not accompany the labor migrant. Overall labor migration affected unaccompanied families more than accompanied families, e.g., only 19% of the unaccompanied families reported increased family unity compared with 56% of accompanied families. Problems within unaccompanied families increased in 43% of the cases but in only 6% of the accompanied families. Many of these problems resulted in children dropping out of school which reflected the control fathers had within the family, separation, or divorce. Yet labor migration reduced family ties with extended family members and neighbors almost equally for both groups. Accompanied families were not as concerned about economic stability in Jordan as unaccompanied families (38% vs. 50%). Perhaps these families tended not to invest remittances received from the labor migrants working in Arab oil-producing countries in Jordan. Both groups were quite concerned about the economic stability in the host countries (66% and 72%, respectively) and the world market (59% and 62%, respectively), however. Since family unity suffers when families do not accompany labor migrants, it is suggested that oil-producing nations that depend on foreign labor should guarantee family unity as a human right.

    Drug pricing is an example of a priority setting in a developing country with official requirements for the use of cost-effectiveness (CE) evidence. To describe the role of economic evidence in drug pricing decisions in Jordan. A prospective review of all applications submitted between November 2013 and May 2015 to the Jordan Food and Drug Association's drug pricing committee was carried out. All applications that involved requests for CE evidence were reviewed. Details on the type of study, the extent, and whether the evidence submitted was part of the formal deliberations were extracted and summarized. The committee reviewed a total of 1608 drug pricing applications over the period of the study. CE evidence was requested in only 11 applications. The submitted evidence was of limited use to the committee due to concerns about quality, relevance of studies, and lack of pharmacoeconomic expertise. There were also no clear rules describing how CE would inform pricing decisions. Limited local data and health economic experience were the main barriers to the use of economic evidence in drug pricing decisions in Jordan. In addition, there are no official rules describing the elements and process by which the CE evidence would inform drug pricing decisions. This study summarized accumulated observations for the current use of economic evaluations and evidence-based decision making in Jordan. Recommendations have been proposed to applicants and key decision makers to enhance the role of economic evidence in influencing health policies and evidence-based decision making across priority settings.

    1989-01-01

    Under the West Valley Demonstration Project Act, Public Law 96-368, liquid high-level radioactive waste stored at the Western New York Nuclear Services Center, West Valley, New York, that resulted from spent nuclear fuel reprocessing operations conducted between 1966 and 1972, is to be solidified in borosilicate glass and transported to a federal repository for geologic disposal. A major milestone was reached in May 1988 when the Project began reducing the volume of the liquid high-level waste. By the end of 1988, approximately 15 percent of the initial inventory had been processed into two waste streams. The decontaminated low-level liquid waste is being solidified in cement. The high-level waste stream is being stored in an underground tank pending its incorporation into borosilicate glass. Four tests of the waste glass melter system were completed. These tests confirmed equipment operability, control system reliability, and provided samples of waste glass for durability testing. In mid-1988, the Department validated an integrated cost and schedule plan for activities required to complete the production of the waste borosilicate glass.

  11. Thermochemical Properties of Nicotine Salts

    Directory of Open Access Journals (Sweden)

    2014-12-01

    Full Text Available The thermal gravimetric analysis (TGA and differential scanning calorimetry (DSC results presented in this report clearly show that the thermal stability and the endothermic peak nicotine release temperatures are different for different nicotine salts and these temperatures appear to be linked to the general microstructural details of the salt itself. In addition, the peak nicotine release temperatures are highly dependent upon the sample size used. The heat of vaporization for neat (non-protonated nicotine is also sample-size dependent. The TGA data showed that the least stable of the salts tested at elevated temperatures was the liquid salt nicotine triacetate followed by the crystalline materials (e.g., nicotine gallate and finally, the amorphous salts (e.g., nicotine alginate. The DSC results revealed that the liquid and crystalline salts exhibit nicotine release endotherms that are strongly related to the sample weight being tested. The amorphous salts show nicotine endotherm peak temperatures that are nearly independent of the sample weight. The range of peak nicotine release temperatures varied depending upon the specific salts and the sample size from 83 oC to well over 200 oC. Based on these results, the evolution of nicotine from the nicotine salt should be expected to vary based on the composition of the salt, the details of its microstructure, and the amount of nicotine salt tested.

    A large amount of waste is generated by buildings over their life cycle, from construction and operation to destruction. Sustainable design principles and recycling programs in buildings can help moderate this waste. The simplest way is directly through the materials used in the building's construction. The materials and resources used should focus on the health and productivity consequences for the building's inhabitants and its environmental, social and economic impacts. This aim of this study is to make certain recommendations with respect to the use of sustainable building materials and resources in indoor spaces in Jordan. A general overview of collection and storage of recyclable materials, waste management, material reuse, and green and rapidly renewable materials is given. Sustainable material usage in the elements of interior design in Jordan is also discussed in two case studies. A set of indicators is proposed which identify the ideal sustainable materials and resources for use in interior design in Jordan to provide a healthy living environment.

    The aims of this study are to assess cigarette and hookah smoking rates amongst adult population in Jordan and to determine predictors of smoking status. Selected beliefs, perceptions and attitudes toward cigarettes and hookah smoking were also assessed. This cross-sectional study was conducted in five regional governorates of Jordan through face-to-face interviews on a random sample of adult population aged 18-79 years. Data was collected using a piloted questionnaire based on the Global Adult Tobacco Questionnaire. The overall prevalence of cigarette smoking in our sample (869) was 59.1 % amongst males and 23.3 % amongst females, while the overall prevalence of hookah smoking was 18.9 % amongst males and 23.1 % amongst females. Leisure and imitation were the most commonly reported reasons for smoking. Regardless of smoking status, people were aware of health risks associated smoking and also had negative perceptions toward smoking. Smoking rates for both genders have reached alarmingly high rates in Jordan. There is an urgent need for a comprehensive national programme to target the country's growing burden of smoking. Suggestions on leisure time activities should be included in such programmes.

    2016-04-01

    We describe an agent based hydro-economic model of groundwater irrigated agriculture in the Jordan Highlands. The model employs a Multi-Agent-Simulation (MAS) framework and is designed to evaluate direct and indirect outcomes of climate change scenarios and policy interventions on farmer decision making, including annual land use, groundwater use for irrigation, and water sales to a water tanker market. Land use and water use decisions are simulated for groups of farms grouped by location and their behavioural and economic similarities. Decreasing groundwater levels, and the associated increase in pumping costs, are important drivers for change within Jordan'S agricultural sector. We describe how this is considered by coupling of agricultural and groundwater models. The agricultural production model employs Positive Mathematical Programming (PMP), a method for calibrating agricultural production functions to observed planted areas. PMP has successfully been used with disaggregate models for policy analysis. We adapt the PMP approach to allow explicit evaluation of the impact of pumping costs, groundwater purchase fees and a water tanker market. The work demonstrates the applicability of agent-based agricultural decision making assessment in the Jordan Highlands and its integration with agricultural model calibration methods. The proposed approach is designed and implemented with software such that it could be used to evaluate a variety of physical and human influences on decision making in agricultural water management.

    2011-01-01

    Indigenous oil shale deposits could satisfy Jordan's demand for liquid and gaseous fuels as well as electricity for many centuries. Markets also exist for raw and retorted oil shale, spent shale, and for sulfur recovered during the upgrading and refining of crude shale oil. Although the potential benefits of oil shale development are substantial, complex and expensive facilities would be required, and these have serious economic, environmental, and social implications for the Kingdom and its people. In January 2006, the United States Trade and Development Agency (USTDA) awarded a grant to the Jordanian Ministry of Planning and International Cooperation to support the analysis of current oil shale processing technologies and the application of international expertise to the development of a oil shale industry in Jordan. The goal of the technical assistance project was to help the Government of Jordan (GoJ) establish short and long-term strategies for oil shale development and to facilitate the commercial production of shale oil in the country. This paper discusses the results of the project. The Kingdom's current energy situation and its previous work on oil shale are summarized, and the incentives and restraints on oil shale commercialization are described. Impediments to development are identified, and possible governmental responses are assessed. (author)

Public and private schools were randomly selected from a random sample of cities from each region. The socioeconomic status of the sampling locations was assessed using several indicators including education, income, healthcare and housing conditions. For each participating subject, anthropometrics were obtained. SS, underweight, overweight and obesity were defined using Center of Disease Control's (CDC) growth charts. Median Z-scores for each region, age and gender were calculated. The Central and Northern regions enjoyed higher socioeconomic status compared to rural Southern regions. The overall prevalence of SS, underweight, overweight, and obesity were 4.9 %, 5.7 %, 17.3 %, and 15.7 %, respectively. SS and underweight were most prevalent in the rural South, while obesity was highest in the Central region. Females were more likely to be overweight, while males were more likely to be obese. Private schools had higher prevalence of obesity and overweight than public ones. Variations in height and weight among Jordanian school children might be affected by socioeconomic status.

    Transboundary aquifers are ubiquitous and strategically important to global food and water security. Yet these shared resources are being depleted at an alarming rate. Focusing on the Disi aquifer, a key nonrenewable source of groundwater shared by Jordan and Saudi Arabia, this study develops a two-stage game that evaluates optimal transboundary strategies of common-pool resource exploitation under various assumptions. The analysis relies on estimates of agricultural water use from satellite imagery, which were obtained using three independent remote sensing approaches. Drawdown response to pumping is simulated using a 2-D regional aquifer model. Jordan and Saudi Arabia developed a buffer-zone strategy with a prescribed minimum distance between each country's pumping centers. We show that by limiting the marginal impact of pumping decisions on the other country's pumping costs, this strategy will likely avoid an impeding tragedy of the commons for at least 60 years. Our analysis underscores the role played by distance between wells and disparities in groundwater exploitation costs on common-pool overdraft. In effect, if pumping centers are distant enough, a shared aquifer no longer behaves as a common-pool resource and a tragedy of the commons can be avoided. The 2015 Disi aquifer pumping agreement between Jordan and Saudi Arabia, which in practice relies on a joint technical commission to enforce exclusion zones, is the first agreement of this type between sovereign countries and has a promising potential to avoid conflicts or resolve potential transboundary groundwater disputes over comparable aquifer systems elsewhere.

    Coastal marine Gasterosteus aculeatus were captured from seven locations along the Pacific coast of North America, ranging across 21·8° latitude to test Jordan's rule, i.e. that vertebral number should increase with increasing latitude for related populations of fish. Vertebral number significantly increased with increasing latitude for both total and caudal vertebral number. Increasing length with latitude (sensu Bergmann's rule) was also supported, but the predictions for Jordan's rule held when controlling for standard length. Pleomerism was weakly evidenced. Gasterosteus aculeatus exhibited sexual dimorphism for Jordan's rule, with both sexes having more vertebrae at higher latitudes, but only males showing a positive association between latitude and the ratio of caudal to abdominal vertebrae. The number of dorsal- and anal-fin rays and basals increased with increasing latitude, while pectoral-fin ray number decreased. This study reinforces the association between phenotypic variation and environmental variation in marine populations of G. aculeatus. © 2017 The Fisheries Society of the British Isles.

    Highlights: • The potential of utilizing biomass as an energy source in Jordan is investigated. • The biomass thermal energy represents 10.2% of the total primary energy. • Bioenergy production depends on biomass availability, conversion and recovery efficiency. - Abstract: This work investigates the status and potential of utilizing biomass as an energy source in Jordan. The amount of waste and residue is estimated to be 6.680 million tons for the year 2011. Two scenarios were investigated: biogas production and thermal treatment. The amount of biogas that can be produced from various biomass sources in Jordan is estimated at 428 MCM. The equivalent annual power production is estimated at 698.1 GW h. This is equivalent to about 5.09% of the consumed electricity (13,535 GW h) and 39.65% of the imported electricity in 2011. The alternative scenario of thermal treatment was investigated. The total theoretical thermal energy that can be obtained assuming 70% conversion efficiency is equivalent to 779 thousand toe (5.33 million barrels of crude oil) which amounts to 10.2% of the total primary energy consumed in 2011. Due to biomass collection and recovery challenges, the energy availability factor varies for the different resources. Hence, contribution of the different biomass resources can significantly vary

    Refugees in Jordan have an increased burden of cancer due to hard conditions and low income. An increase in awareness of the early signs of cancer could prompt early diagnosis. The current study aims to explore the level of cancer knowledge and barriers to seeking care among Syrian refugees in Jordan. A descriptive cross-sectional survey design was used. Two hundred and forty-one Syrian refugees living in the north of Jordan completed the Cancer Awareness Measure. The mean age was 27.9 (SD 9.1) years, ranging from 18 to 47 years. More than half (56%) of the participants were female. Participants were able to recognize a low number of symptoms (mean 4.4, SD 2.3) and risk factors (4.7 (out of 11), SD 1.9). The most commonly reported barrier was having no medical insurance (83.4%). Refugees' knowledge of symptoms and risk factors was generally unsatisfactory. Barriers to seeking medical care were prevalent. Much work is needed to overcome barriers and enhance knowledge that can hinder early diagnosis and treatment.

    The transportation sector is responsible for 37% of the total final energy consumption in Jordan, with passenger cars taking a share of 57% in this sector. Improvement of the energy efficiency of the transportation sector can help in alleviating socio-economic pressures resulting from the inflating fuel bill and in lowering the relatively high CO 2 emission intensity. Current legislations mandate that all passenger cars operating in Jordan are to be powered with spark ignition engines using gasoline fuel. This paper examines potential benefits that can be achieved through the introduction of diesel cars to the passenger cars market in Jordan. Three scenarios are suggested for implementation and investigated with a forecasting model on the basis of local and global trends over the period 2007-2027. It is demonstrated that introducing diesel passenger cars can slow down the growth of energy consumption in the transportation sector resulting in significant savings in the national fuel bill. It is also shown that this is an effective and feasible option for cutting down CO 2 emissions

    The Hashemite Kingdom of Jordan is an example of a country that suffers from high water scarcity. Additionally, due to the economic drivers in the country, such as phosphate and potash extraction and pharmaceutical production, the little fresh water that remains is generally polluted. The infrastructure, often antiquated in urban areas and non-existent in rural areas, also contributes to poor water conditions and to the spread of waterborne diseases. This paper examines the socioeconomic factors that contribute to diarrhea and hepatitis A on a macro level in Jordan and discusses the public-policies that government officials could use to abate those problems. Ordinary least squares time series models are used to understand the macro-level variables that impact the incidence of these diseases in Jordan. Public health expenditure has a significant impact on reducing their incidence. Furthermore, investment in sanitation facilities in rural regions is likely to reduce the number of cases of hepatitis A. Perhaps the most surprising outcome is that importation of goods and services likely results in a decrease in cases of hepatitis A. However, income has little impact on the incidence of diarrhea and hepatitis A.

    Home care aims at supporting people with various degrees of dependency to remain at home rather than use residential, long-term, or institutional-based nursing care. Demographic, epidemiological, social, and cultural trends in Jordan as in other countries are changing the traditional patterns of care with growing emphasis on home care. The purpose of this study is to highlight the most common challenges related to home health care (HHC) services in Jordan as perceived by the managers of HHC agencies. Methods: a descriptive qualitative design that depends on focus group discussions has been used to collect data from a sample of 18 managers who met the selection criteria and who are willing to participate, the study found that, the main challenges of HHC services as perceived by managers were: shortage of female staff, lack of governance and regulation, poor management, unethical practices, lack of referral systems, and low accessibility of the poor and less privileged as HHC services are not included in health insurance schemes, it concludes also that the home health care industry in Jordan is facing many challenges and problems that may have negative effects on the effectiveness, efficiency, equity and quality of services and should be addressed by health policy makers.

Particular emphasis is given to the 1929 Kharkov conference where Jordan not only presents a quite modern looking panorama about the state of art, but were some of his ideas already preempt an intrinsic point of view about a future QFT liberated from the classical parallelism and quantum field theory, a new approach for which the conceptional basis began to emerge only 30 years later. Two quite profound subjects in which Jordan was far ahead of his contemporaries will be presented in separate sections: 'Bosonization and Re-fermionization instead of Neutrino theory of Light' and N onlocal gauge invariants and an algebraic monopole quantization . The last section contains scientific episodes mixed with biographical details. It includes remarks about his much criticized conduct during the NS regime. Without knowing about his entanglement with the Nazis it is not possible to understand that such a giant of particle physics dies without having received a Nobel prize. (author)

    To investigate the present familiarity, knowledge, and attitudes of Jordanians towards epilepsy. This is a cross-sectional study that was conducted over a 6-month period, from April 2006 to October 2006 at the family clinic of Jordan University Hospital, Amman, Jordan. A face-to-face questionnaire interview was conducted with 600 non-epileptic adults who visited the clinic during the study period. The sample matched the overall Jordanian population for literacy rate, however, included a higher proportion of females, and consequently findings may be taken as being only moderately representative of the Jordanian population. Ninety-eight percent of the respondents had heard about epilepsy, 47.3% knew someone with epilepsy, and 39.7% had witnessed a seizure. The major source of knowledge was word of mouth; knowledge about causes and treatment were far below the results reported in western countries. In addition, negative attitudes were present with regard to marriage and employment of epileptic patients (86.8% objected to marriage and 50.8% objected to employment). Eighty-three percent of respondents admitted that their knowledge of epilepsy was not satisfactory and were willing to learn more about epilepsy. The television was believed to be the most efficient and preferred way to disseminate knowledge about epilepsy. Although this study does not represent the whole Jordanian population, however, it demonstrated lack of knowledge and emphasized the extent of negative as well as positive attitudes towards epilepsy in Jordan.

    The Hansel Valley ash bed lies within 5 cm of the base of deposits of Lake Bonneville (???28 ka) in the vicinity of Great Salt Lake and provides a useful stratigraphic marker for this area of the lake basin. However, it has not been matched to an eruptive edifice, presumably because such an edifice was eroded by waves of Lake Bonneville. We present data for the chemical composition of the tephra and for possible matching lavas and tephras of the region, as well as grain size data for the tephra in an attempt to identify the location of the eruption. Matches with other tephras are negative, but lavas near the coarsest ash deposits match well with the distinctive high values of TiO2 and P2O5 of the ash. Neither chemistry nor grain size data points uniquely to a source area, but an area near the northwest shore of Great Salt Lake and within Curlew Valley is most likely. The Hansel Valley ash is an example of an ash that has no direct numerical date from proximal deposits, despite considerable study, yet nonetheless is useful for stratigraphic studies by virtue of its known stratigraphic position and approximate age. Basaltic tephras commonly are not as widespread as their rhyolitic counterparts, and in some cases apparently are produced by eruptive sources that are short lived and whose edifices are not persistent. ?? 2007 Elsevier Ltd and INQUA.

    The Antarctic Dry Valleys (ADV) comprise the largest ice-free region of Antarctica. Precipitation almost always occurs as snow, relative humidity is frequently low, and mean annual temperatures are about -20 C. The ADV soils have previously been categorized into three soil moisture regimes: subxerous, xerous and ultraxerous, based on elevation and climate influences. The subxerous regime is predominately a coastal zone soil, and has the highest average temperature and precipitation, while the ultraxerous regime occurs at high elevation (>1000 m) and have very low temperature and precipitation. The amounts and types of salts present in the soils vary between regions. The nature, origin and significance of salts in the ADV have been previously investigated. Substantial work has focused on soil formation in the ADVs, however, little work has focused on the mineralogy of secondary alteration phases. The dominant weathering process in the ADV region is physical weathering, however, chemical weathering has been well documented. The objective of this study was to characterize the chemistry and mineralogy, including the alteration mineralogy, of soils from two sites, a subxerous soil in Taylor Valley, and an ultraxerous soil in University Valley. The style of aqueous alteration in the ADVs may have implications for pedogenic processes on Mars.

  15. The material flow of salt

    Salt (NaCl) is a universal mineral commodity used by virtually every person in the world. Although a very common mineral today, at one time it was considered as precious as gold in certain cultures. This study traces the material flow of salt from its origin through the postconsumer phase of usage. The final disposition of salt in the estimated 14,000 different uses, grouped into several macrocategories, is traced from the dispersive loss of salt into the environment to the ultimate disposal of salt-base products into the waste stream after consumption. The base year for this study is 1990, in which an estimated 196 million short tons of municipal solid waste was discarded by the US population. Approximately three-fourths of domestic salt consumed is released to the environment and unrecovered while about one-fourth is discharged to landfills and incinerators as products derived from salt. Cumulative historical domestic production, trade, and consumption data have been compiled to illustrate the long-term trends within the US salt industry and the cumulative contribution that highway deicing salt has had on the environment. Salt is an important component of drilling fluids in well drilling. It is used to flocculate and to increase the density of the drilling fluid in order to overcome high down-well gas pressures. Whenever drilling activities encounter salt formations, salt is added to the drilling fluid to saturate the solution and minimize the dissolution within the salt strata. Salt is also used to increase the set rate of concrete in cemented casings. This subsector includes companies engaged in oil, gas, and crude petroleum exploration and in refining and compounding lubricating oil.

    Simulating transport and storage of dissolved solids in surface water and underlying alluvial aquifer is essential to evaluate the impacts of surface water operations, groundwater pumping, and climate variability on the spatial and temporal variability of salinity in the Rio Grande Basin. In this study, we developed a monthly RiverWare water quantity and quality model to simulate the both concentration and loads of dissolved solids for the Rincon Valley, New Mexico from Caballo Reservoir to Leasburg Dam segment of the Rio Grande. The measured flows, concentration and loads of dissolved solids in the main stream and drains were used to develop RiveWare model using 1980-1988 data for calibration, and 1989-1995 data for validation. The transport of salt is tracked using discretized salt and post-process approaches. Flow and salt exchange between the surface water and adjacent groundwater objects is computed using "soil moisture salt with supplemental flow" method in the RiverWare. In the groundwater objects, the "layered salt" method is used to simulate concentration of the dissolved solids in the shallow groundwater storage. In addition, the estimated local inflows under different weather conditions by using a calibrated Soil Water Assessment Tool (SWAT) were fed into the RiverWare to refine the simulation of the flow and dissolved solids. The results show the salt concentration and loads increased at Leasburg Dam, which indicates the river collects salts from the agricultural return flow and the underlying aquifer. The RiverWare model with the local inflow fed by SWAT delivered the better quantification of temporal and spatial salt exchange patterns between the river and the underlying aquifer. The results from the proposed modeling approach can be used to refine the current mass-balance budgets for dissolved-solids transport in the Rio Grande, and provide guidelines for planning and decision-making to control salinity in arid river environment.

    2016-08-01

    The valley-dependent energy band and transport property of graphene under a periodic magnetic-strained field are studied, where the time-reversal symmetry is broken and the valley degeneracy is lifted. The considered superlattice is composed of two different barriers, providing more degrees of freedom for engineering the electronic structure. The electrons near the K and K' valleys are dominated by different effective superlattices. It is found that the energy bands for both valleys are symmetric with respect to ky=-(AM+ξ AS) /4 under the symmetric superlattices. More finite-energy Dirac points, more prominent collimation behavior, and new crossing points are found for K' valley. The degenerate miniband near the K valley splits into two subminibands and produces a new band gap under the asymmetric superlattices. The velocity for the K' valley is greatly renormalized compared with the K valley, and so we can achieve a finite velocity for the K valley while the velocity for the K' valley is zero. Especially, the miniband and band gap could be manipulated independently, leading to an increase of the conductance. The characteristics of the band structure are reflected in the transmission spectra. The Dirac points and the crossing points appear as pronounced peaks in transmission. A remarkable valley polarization is obtained which is robust to the disorder and can be controlled by the strain, the period, and the voltage.

    The inland valley in Africa are common landscapes that have favorable conditions for agricultural production. Compared to the surrounding uplands they are characterized by a relatively high and secure water availability and high soil fertility levels. Inland valleys thus have a high agricultural
