Stress from dominance ranks in human societies, or that of other social animals, especially nonhuman primates, can have negative influences on health. Individuals holding different social status may be burdened with various stress levels. The middle class experiences a special stress situation within the dominance hierarchy due to its position between the higher and lower classes. Behaviorally, questions about where middle-class stress comes from and how individuals adapt to middle-class stress remain poorly understood in nonhuman primates. In the present study, social interactions, including aggression, avoidance, grooming and mounting behaviors, between beta males, as well as among group members holding higher or lower social status, were analyzed in captive male-only cynomolgus monkey groups. We found that aggressive tension from the higher hierarchy members was the main origin of stress for middle-class individuals. However, behaviors such as attacking lower hierarchy members immediately after being the recipient of aggression, as well as increased avoidance, grooming and mounting toward both higher and lower hierarchy members helped alleviate middle-class stress and were particular adaptations to middle-class social status.

What Is Middle Class about the Middle Classes around the World?

We expect a lot from the middle classes. At least three distinct arguments about the special economic role of the middle class are traditionally made. In one, new entrepreneurs armed with a capacity and a tolerance for delayed gratification emerge from the middle class and create employment and productivity growth for the rest of society. In a second, perhaps more conventional view, the middle class is primarily a source of vital inputs for the entrepreneurial class: it is their "middle class...

The Mobility of Italy’s Middle Income Group

Directory of Open Access Journals (Sweden)

Chiara Assunta Ricci

2016-06-01

Full Text Available The bulk of economic studies on income distribution focus on the poor and/or on the rich, mostly ignoring those who fall between these two categories. Research on the polarisation of incomes reverses this perspective, considering the middle-income group as a crucial element of analysis. The exploration of the income dynamics of the middle-income group is particularly relevant in the case of Italy. There, it has helped explaining the gap between the empirical evidence of stability in the main distributional indices and the worsening of confidence and expectations among Italian households since the 2000s, already before the crisis. This paper investigates the drivers of mobility of the middle-income group in Italy during the recent recession, with the aim of assessing the changes in the vulnerability of this group to downward mobility. Our findings reveal a general impoverishment of the middle-income group due to the recession and highlight an increasing rigidity of the Italian social structure. Lower entry and exit rates between groups emerge after 2008, possibly due to a growing weakness of the welfare state and the increasing inability of families to cope with unforeseen financial difficulties.

Prescribed journeys through life: Cultural differences in mental time travel between Middle Easterners and Scandinavians.

Science.gov (United States)

Ottsen, Christina Lundsgaard; Berntsen, Dorthe

2015-12-01

Mental time travel is the ability to remember past events and imagine future events. Here, 124 Middle Easterners and 128 Scandinavians generated important past and future events. These different societies present a unique opportunity to examine effects of culture. Findings indicate stronger influence of normative schemas and greater use of mental time travel to teach, inform and direct behaviour in the Middle East compared with Scandinavia. The Middle Easterners generated more events that corresponded to their cultural life script and that contained religious words, whereas the Scandinavians reported events with a more positive mood impact. Effects of gender were mainly found in the Middle East. Main effects of time orientation largely replicated recent findings showing that simulation of future and past events are not necessarily parallel processes. In accordance with the notion that future simulations rely on schema-based construction, important future events showed a higher overlap with life script events than past events in both cultures. In general, cross-cultural discrepancies were larger in future compared with past events. Notably, the high focus in the Middle East on sharing future events to give cultural guidance is consistent with the increased adherence to normative scripts found in this culture.

Harwood, David S.

1966-01-01

The Cupsuptic quadrangle, in west-central Maine, lies in a relatively narrow belt of pre-Silurian rocks extending from the Connecticut River valley across northern New Hampshire to north-central Maine. The Albee Formation, composed of green, purple, and black phyllite with interbedded-quartzite, is exposed in the core of a regional anticlinorium overlain to the southeast by greenstone of the Oquossoc Formation which in turn is overlain by black slate of the Kamankeag Formation. In the northern part of the quadrangle the Albee Formation is overlain by black slate, feldspathic graywacke, and minor greenstone of the Dixville Formation. The Kamankeag Formation is dated as 1-ate Middle Ordovician by graptolites (zone 12) found near the base of the unit. The Dixville Formation is correlated with the Kamankeag Formation and Oquossoc Formation and is considered to be Middle Ordovician. The Albee Formation is considered to be Middle to Lower Ordovician from correlations with similar rocks in northeastern and southwestern Vermont. The Oquossoc and Kamankeag Formations are correlated with the Amonoosuc and Partridge Formations of northern New Hampshire. The pre-Silurian rocks are unconformably overlain by unnamed rocks of Silurian age in the southeast, west-central, and northwest ninths of the quadrangle. The basal Silurian units are boulder to cobble polymict conglomerate and quartz-pebble conglomerate of late Lower Silurian (Upper Llandovery) age. The overlying rocks are either well-bedded slate and quartzite, silty limestone, or arenaceous limestone. Thearenaceous limestone contains Upper Silurian (Lower Ludlow) brachiopods. The stratified rocks have been intruded by three stocks of biotite-muscovite quartz monzonite, a large body of metadiorite and associated serpentinite, smaller bodies of gabbro, granodiorite, and intrusive felsite, as well as numerous diabase and quartz monzonite dikes. The metadiorite and serpentinite, and possibly the gabbro and granodiorite are Late

Caught in the Middle: Some in Canada’s Middle Class are Doing Well; Others Have Good Reason to Worry

-sector professionals in particular have come to share the human-capital and income characteristics of Canada’s highest-paid managers and professionals, often enjoying greater job security as well. In reality, anxiety over the state of the middle class and its future is actually about the working class. Lumping middle-class factory workers and clerical assistants in with middle-class teachers and nurses — as current political discussion tends to do — obscures the truth about which members of that group are genuinely struggling to keep up. As long as politicians continue to promote policies aimed at helping everyone within such a vague and broad target group, they can only end up misdirecting resources by enriching those who are already doing reasonably well, rather than focusing on those working-class Canadians who truly are not. Already net transfers through the tax system to middle-income groups have grown markedly. These transfers have managed to offset about half the erosion of middle-class incomes in the marketplace. Those transfers have been financed through increased tax payments from high-income groups, but also through shrinking transfers to low-income groups. These developments raise serious policy issues for which there are no simple answers. The breadth of Canada’s middle class obviously means that it encompasses the largest proportion of families, by far. Any further policies aimed at transferring wealth from other income groups to appease middle-class voters will be costly. Given that the main cause for concern is the worsening situation of lowerskilled workers, politicians who truly want to help those struggling in the “middle class,” should focus their efforts on helping Canadians acquire more education and more skills.

To study the effects of life event and coping style on left-behind middle school student mental health. 1405 left-behind middle school students were selected by multi-stage cluster random sampling method and investigated with Middle School Student Mental Health Scale (MSSMHS), Multidimensional Life Events Rating Questionnaire for Middle School Students (MLERQ) and Trait Coping Style Questionnaire (TCSQ). The mental health detection rate of left-behind middle school students was 26.33%. Life event have significant influence on mental health (F = 447.624, P = 0.000). The main effect for negative coping style on mental health was significant (F = 263.669, P = 0.000). Positive coping style have effect on mental health but the main effect was not significant (F = 2.436, P = 0.119). The interaction effect of life event and negative coping style was significant (F = 23.173, P = 0.000). Life event and coping style has a certain effect on left-behind middle school student mental health, but its mechanism is complicated and still uncertain.

Geochemical evaluation of the middle Magdalena basing Colombia

1997-01-01

The chemical composition of 25 crude oils from Tertiary reservoirs and 12 rock extracts from five organic-rich Cretaceous formations in the middle Magdalena Basin, Colombia were studied in detail by geochemical methods in order to understand their genetic relationships. The oils have been geochemically classified into four main groups based on the sulfur content, pristane/phytane, dibenzothiophene /phenanthrene, concentrations of oleanane and terpane distributions. Each group occurs in different geographic locations. Oils were mainly derived from calcareous, siliciclastic and mixture of these two facies of the Upper Cretaceous La Luna Formation. Source-oil correlation is supported by sterane and terpane distributions of and carbon isotope ratios. Some oils in the eastern margin contain relatively higher concentrations of higher plant indicators than the remaining oil samples. The molecular compositions of the oils observed in this study appear to be consistent with the inferred depositional sequence of anoxic marine/pelagic carbonate facies in the north/western sector of the Middle Magdalena, while the eastern sector received a higher proportion of clastic input. This documentation supports the interpretation that the Middle Magdalena oils have been generated 'locally', as opposed to have migrated from the region of the Eastern Cordillera. Biomarker maturity parameters indicate that the majority of oils were generated in the early thermal maturity oil window except the Colorado-38 oil, which was generated in the middle thermal maturity oil window. Oil maturity data also supports the short migration distances of oils from the early-mature source rocks to the reservoir rocks. The composition of some oils (e.g., La Cira, Infantas, Conde and Bonanza) is unusual in that gas chromatographic data contains an n-alkane and isoprenoid distribution normally associated with moderately degraded oils, but they also contain a relatively high abundance of gasoline hydrocarbons

SPECIFICS OF GERMAN FOREIGN POLICY IN THE MIDDLE EAST AND NORTH AFRICA

Г А Ханнанова

2017-12-01

Full Text Available The article is devoted to an analysis of the main factors, determining German policy in the Middle East and North Africa (MENA. More active German military-technical engagement in the settlement of the crises in the region on the modern stage determines relevance of this article’s topic. Based on historical method, author considers the development of German foreign policy in the Arab world, examining the main aspects of the colonial policy of German empire on the threshold of the First and Second World Wars, as well as the prerequisites of the intensification of German-Arabic contacts in the period of Cold War. In accordance with the principals of system analysis Germany’s Middle East policy was investigated in complex, given geopolitical, economic and military aspects. Special emphasis is put on the problem of transformation of Middle East regional order as a factor of political instability. Notwithstanding the rea-sonableness of Germany’s standing for stable and predictable regional order, these goals were challenged owing to the fact that Germany benefits from the regional disorder in terms of increase of its influence. In reliance on the German goals in the Middle East and North Africa, mentioned in the Coalition Agreement of 2013, the author points out the priority of crisis management. At the same time the ethno-confessional conflict potential of the region meets the interests of German military-industrial complex. Increase of Germany’s export of weapons to the Arab states as well as neglecting the restrictions on export go to prove that Germany backs the armaments race in the Middle East. In this regard, German policy is characterized by “double standards” and inconsistency. These specifics can be explained by the ongoing process of Middle East policy shift and searching for new priorities on a long-term horizon. In the conclusion, the author analyzes the specifics and prospects of German policy in MENA region.

The effects of solar particle events on the middle atmosphere

Solar particle events (SPEs) have been investigated since the late 1960's for possible effects on the middle atmosphere. Solar protons from SPEs produce ionizations, dissociations, dissociative ionizations, and excitations in the middle atmosphere. The production of HO(x) and NO(x) and their subsequent effects on ozone can also be computed using energy deposition and photochemical models. The effects of SPE-produced HO(x) species on the odd nitrogen abundance of the middle atmosphere as well as the SPE-produced long term effects on ozone. Model computations indicate fairly good agreement with ozone data for the SPE-induced ozone depletion caused by NO(y) species connected with the August 1972 SPE. The model computations indicate that NO(y) will not be substantially changed over a solar cycle by SPEs. The changes are mainly at high latitudes and are on time scales of several months, after which the NO(y) drifts back to its ambient levels

Full Text Available Hearing loss is a condition affecting millions of people worldwide. Conductive hearing loss (CHL is mainly caused by middle ear diseases. The low frequency area is the pivotal part of speech frequencies and most frequently impaired in patients with CHL. Among various treatments of CHL, middle ear surgery is efficient to improve hearing. However, variable success rates and possible needs for prolonged revision surgery still frustrate both surgeons and patients. Nowadays, increasing numbers of researchers explore various methods to monitor the efficacy of ossicular reconstruction intraoperatively, including electrocochleography (ECochG, auditory brainstem response (ABR, auditory steady state response (ASSR, distortion product otoacoustic emissions (DPOAE, subjective whisper test, and optical coherence tomography (OCT. Here, we illustrate several methods used clinically by reviewing the literature.

Medication errors are a significant global concern and can cause serious medical consequences for patients. Little is known about medication errors in Middle Eastern countries. The objectives of this systematic review were to review studies of the incidence and types of medication errors in Middle Eastern countries and to identify the main contributory factors involved. A systematic review of the literature related to medication errors in Middle Eastern countries was conducted in October 2011 using the following databases: Embase, Medline, Pubmed, the British Nursing Index and the Cumulative Index to Nursing & Allied Health Literature. The search strategy included all ages and languages. Inclusion criteria were that the studies assessed or discussed the incidence of medication errors and contributory factors to medication errors during the medication treatment process in adults or in children. Forty-five studies from 10 of the 15 Middle Eastern countries met the inclusion criteria. Nine (20 %) studies focused on medication errors in paediatric patients. Twenty-one focused on prescribing errors, 11 measured administration errors, 12 were interventional studies and one assessed transcribing errors. Dispensing and documentation errors were inadequately evaluated. Error rates varied from 7.1 % to 90.5 % for prescribing and from 9.4 % to 80 % for administration. The most common types of prescribing errors reported were incorrect dose (with an incidence rate from 0.15 % to 34.8 % of prescriptions), wrong frequency and wrong strength. Computerised physician rder entry and clinical pharmacist input were the main interventions evaluated. Poor knowledge of medicines was identified as a contributory factor for errors by both doctors (prescribers) and nurses (when administering drugs). Most studies did not assess the clinical severity of the medication errors. Studies related to medication errors in the Middle Eastern countries were relatively few in number and of poor quality

The fragmented character of Middle Palaeolithic stone tool technology.

Turq, Alain; Roebroeks, Wil; Bourguignon, Laurence; Faivre, Jean-Philippe

2013-11-01

The importance of the transport of stone artefacts in structuring Neandertal lithic assemblages has often been addressed, but the degree to which this led to fragmentation of lithic reduction over Middle Palaeolithic landscapes has not been explicitly studied thus far. Large-scale excavations of Middle Palaeolithic open-air sites and refitting studies of the retrieved assemblages have yielded new, high-resolution data on the mobile aspects of Neandertal stone tool technology. In this paper, we integrate lithic technology and raw material data from recent studies of Middle Palaeolithic open-air and rock shelter sites in Western Europe. We demonstrate that the results of a variety of typological, technological (especially refitting), and lithological studies have important consequences for our knowledge of the acquisition of raw materials and subsequent production, usage and discard of stone artefacts in the Middle Palaeolithic. Neandertal production and use of stone tools was fragmented in three domains: the spatial, the temporal and the social domain. We show that this versatile segmentation of stone artefact handling strategies is a main determinant of the character of the Neandertal archaeological record. Our data testify to ubiquitous and continuous transport of stone artefacts of a wide variety of forms, picked by Neandertals using selection criteria that were sometimes far removed from what archaeologists have traditionally considered, and to some degree still consider, to be desired end products of knapping activities. The data presented here testify to the variability and versatility of Middle Palaeolithic stone tool technology, whose fragmented character created very heterogeneous archaeological assemblages, usually the product of a wide variety of independent import, use, discard and/or subsequent transport events.

Objectives: Economic evaluations on influenza vaccination from low resource settings are scarce and have not been evaluated using a systematic approach. Our objective was to conduct a systematic review on the value for money of influenza vaccination in low- and middle-income countries. Methods: PubMed and EMBASE were searched for economic evaluations published in any language between 1960 and 2011. Main outcome measures were costs per influenza outcome averted, costs per quality-adjusted life years gained or disability-adjusted life years averted, costs per benefit in monetary units or cost-benefit ratios. Results: Nine economic evaluations on seasonal influenza vaccine met the inclusion criteria. These were model- or randomized-controlled-trial (RCT)-based economic evaluations from middle-income countries. Influenza vaccination provided value for money for elderly, infants, adults and children with high-risk conditions. Vaccination was cost-effective and cost-saving for chronic obstructive pulmonary disease patients and in elderly above 65 y from model-based evaluations, but conclusions from RCTs on elderly varied. Conclusion: Economic evaluations from middle income regions differed in population studied, outcomes and definitions used. Most findings are in line with evidence from high-income countries highlighting that influenza vaccine is likely to provide value for money. However, serious methodological limitations do not allow drawing conclusions on cost-effectiveness of influenza vaccination in middle income countries. Evidence on cost-effectiveness from low-income countries is lacking altogether, and more information is needed from full economic evaluations that are conducted in a standardized manner.

Short wavelength lateral variability of lithospheric mantle beneath the Middle Atlas (Morocco) as recorded by mantle xenoliths

The Middle Atlas is a region where xenolith-bearing volcanism roughly coincides with the maximum of lithospheric thinning beneath continental Morocco. It is therefore a key area to study the mechanisms of lithospheric thinning and constrain the component of mantle buoyancy that is required to explain the Moroccan topography. Samples from the two main xenolith localities, the Bou Ibalghatene and Tafraoute maars, have been investigated for their mineralogy, microstructures, crystallographic preferred orientation, and whole-rock and mineral compositions. While Bou Ibalghatene belongs to the main Middle Atlas volcanic field, in the 'tabular' Middle Atlas, Tafraoute is situated about 45 km away, on the North Middle Atlas Fault that separates the 'folded' Middle Atlas, to the South-East, from the 'tabular' Middle Atlas, to the North-West. Both xenolith suites record infiltration of sub-lithospheric melts that are akin to the Middle Atlas volcanism but were differentiated to variable degrees as a result of interactions with lithospheric mantle. However, while the Bou Ibalghatene mantle was densely traversed by high melt fractions, mostly focused in melt conduits, the Tafraoute suite records heterogeneous infiltration of smaller melt fractions that migrated diffusively, by intergranular porous flow. As a consequence the lithospheric mantle beneath Bou Ibalghaten was strongly modified by melt-rock interactions in the Cenozoic whereas the Tafraoute mantle preserves the record of extensional lithospheric thinning, most likely related to Mesozoic rifting. The two xenolith suites illustrate distinct mechanisms of lithospheric thinning: extensional thinning in Tafraoute, where hydrous incongruent melting triggered by decompression probably played a key role in favouring strain localisation, vs. thermal erosion in Bou Ibalghatene, favoured and guided by a dense network of melt conduits. Our results lend support to the suggestion that lithospheric thinning beneath the Atlas

Energy efficient three-layer panels and elastic compliance of their middle layer

Directory of Open Access Journals (Sweden)

Petrov Stanislav

2017-01-01

Full Text Available Three-layer panels are referred to light weight energy efficient building envelopes. According to current trends, mineral wool from basalt fiber is preferable to be used as panels middle layer. All three-layers of the construction together account for mechanical properties, though these layers taken separately have very different mechanical properties. The work of such a composite design has a number of features that require careful consideration when calculating the panels for strength. Thus, it has not yet been described how squeeze reduction of a relatively soft middle layer affects the load bearing capacity of a panel. When panels are exposed to external loads, their middle layer is squeezed thus changing the characteristics of the panel. This effect is particularly evident in supporting structures. Besides, squeeze reduction of the middle layer changes its elastic-plastic propeties. The purpose of this work is to study the effect of the middle layer of an energy efficient panel squeeze reduction on its load bearing capacity. When solving this task, the authors worked out a methodology which takes into account squeeze reduction of a middle layer and its effect on load bearing capacity of the panel. The researches introduced an algorithm for solving this task and created a tool that allows to easily receive the exact solution. The paper presents this methodology and describes a computer program for calculating three-layer panels with account of changing elastic compliance of a middle layer. The main result of the work is an extended methodology of calculation of the panels and an obtained engineering tool that allows to quickly obtain an extended solution.

Hydrogeology of Middle Canyon, Oquirrh Mountains, Tooele County, Utah

Science.gov (United States)

Gates, Joseph Spencer

1963-01-01

Geology and climate are the principal influences affecting the hydrology of Middle Canyon, Tooele County, Utah. Reconnaissance in the canyon indicated that the geologic influences on the hydrology may be localized; water may be leaking through fault and fracture zones or joints in sandstone and through solution openings in limestone of the Oquirrh formation of Pennsylvanian and Permian age. Surficial deposits of Quaternary age serve as the main storage material for ground water in the canyon and transmit water from the upper canyon to springs and drains at the canyon mouth. The upper canyon is a more important storage area than the lower canyon because the surficial deposits are thicker, and any zones of leakage in the underlying bedrock of the upper canyon probably would result in greater leakage than would similar outlets in the lower canyon.The total annual discharge from Middle Canyon, per unit of precipitation, decreased between 1910 and 1939. Similar decreases occurred in Parleys Canyon in the nearby Wasatch Range and in other drainage basins in Utah, and it is likely that most of the decrease in discharge from Middle Canyon and other canyons in Utah is due to a change in climate.Chemical analyses of water showed that the high content of sulfate and other constituents in the water from the Utah Metals tunnel, which drains into Middle Canyon, does not have a significant effect on water quality at the canyon mouth. This suggests that much of the tunnel water is lost from the channel by leakage, probably in the upper canyon, during the dry part of the year.Comparison of the 150 acre-feet of water per square mile of drainage area discharged by Middle Canyon in 1947 with the 623 and 543 acre-feet per square mile discharged in 1948 by City Creek and Mill Creek Canyons, two comparable drainage basins in the nearby Wasatch Range, also suggests that there is leakage in Middle Canyon.A hydrologic budget of the drainage basin results in an estimate that about 3,000 acre

In Phase 1 of the 'Feasibility Study on Commercialized Fast Reactor Cycle Systems (F/S)', an advanced loop type reactor has been selected as a promising concept of sodium-cooled middle-scale modular reactor, which has a possibility to fulfill the design requirements of the F/S. In Phase 2 of the F/S, it is planed to precede a preliminary conceptual design of a sodium-cooled middle-scale modular reactor based on the design of the advanced loop type reactor. Through the design study, it is intended to construct such a plant concept that can show its attraction and competitiveness as a commercialized reactor. This report summarizes the results of the design study on the sodium-cooled middle-scale modular reactor performed in JFY2001, which is the first year of Phase 2. As the construction cost of the sodium-cooled middle-scale modular reactor, which has been constructed in Phase 1, was about 10% higher than that of the sodium-cooled large-scale reactor, a new concept of the middle-scale modular reactor, which is expected to be equal to the large-scale reactor from a viewpoint of economic competitiveness, has been re-constructed based on the design of the advanced loop type reactor. After that, fundamental specifications of main systems and components for the new concept have been set, and critical subjects related to safety, structural integrity, thermal hydraulics, operability, maintainability and economy have been examined and evaluated. As a result of this study, the plant concept of the sodium-cooled middle-scale modular reactor has been constructed, which has a prospect to satisfy the economic goal (construction cost: less than 200,000 yens/kWe, etc.) and has a prospect to solve the critical subjects. From now on, reflecting the results of elemental experiments, the preliminary conceptual design of this plant will be preceded toward the selection for narrowing down candidate concepts at the end of Phase 2.

Full Text Available The petrophysical analysis of the early Eocene Sui Main Limestone (SML has been conducted in Kharnhak-1 well for the prospect of the hydrocarbon exploration of the Khairpur-Jacobabad High, Middle Indus Basin, Pakistan. The petrophysical analysis of SML is carried out on the basis of well logs including gamma ray, spontaneous potential, resistivity, neutron, and density logs. These analyses lead to interpreting the vertical distribution of porosity and permeability in order to measure the reservoir potential of the SML. The Archie equation was used to assess the petrophysical characteristics. The SML has good porosity and poor permeability with positive correlation coefficient between the two parameters. The average volume of shale is 18%. The log signature of SML shows dominance of carbonates (limestone. The reservoir quality of the SML in Kharnhak-1 well is such that it is 77% water saturated. The porosity (x varies inversely with formation resistivity factor (F and compressional wave velocity (Vp. However, F and Vp are directly related with each other. Thus, the electric and elastic properties of the carbonate rocks can be influenced by postdepositional alterations, which include porosity enhancement and reduction processes respectively.

2017-05-01

Three tetrapod track assemblages from the early-middle Mesozoic of southern Tunisia are reported. The strata exposed at the Tejra 2 clay-pit near the Medenine and Rehach site, located in the vicinity of Kirchaou, contain the first tetrapod tracks found in the Triassic of Tunisia. The Middle Jurassic (early Aalenian) dinosaur tracks are reported from the Mestaoua plain near Tataouine. In the Middle Triassic outcrop of the Tejra 2 clay-pit, tridactyl tracks of small and medium-sized dinosauromorphs, were discovered. These tracks represent the oldest evidence of dinosaur-lineage elements in the Triassic deposits of Tunisia. Similar tracks have been described from the Middle Triassic of Argentina, France and Morocco. An isolated set of the manus and pes of a quadrupedal tetrapod discovered in Late Triassic Rehach tracksite is referred to a therapsid tracemaker. The Middle Jurassic deposits of the Mestaoua plain reveal small and large tridactyl theropod dinosaur tracks (Theropoda track indet. A-C). Based on comparison with the abundant record of Triassic tetrapod ichnofossils from Europe and North America, the ichnofauna described here indicates the presence of a therapsid-dinosauromorph ichnoassociation (without typical Chirotheriidae tracks) in the Middle and Late Triassic, which sheds light on the dispersal of the Middle-Upper Triassic tetrapod ichnofaunas in this part of Gondwana. The reported Middle Jurassic ichnofauna show close similarities to dinosaur track assemblages from the Lower and Middle Jurassic of northwestern Africa, North America, Europe and also southeastern Asia. Sedimentological and lithostratigraphic data of each new tracksite have been defined on published data and new observations. Taken together, these discoveries present a tantalizing window into the evolutionary history of tetrapods from the Triassic and Jurassic of southern Tunisia. Given the limited early Mesozoic tetrapod record from the region, these discoveries are of both temporal and

Full Text Available Background & aim: Breast, cervical, and colorectal cancers are the leading causes of mortality among women, the incidence rate of which has an upward trend with advancing age. Although cost-effective, easy, and available screening programs can help control these types of cancer in their early stages, it seems that cancer screening programs have not been implemented effectively. In this study, we investigated the rate of cancer screening practice in middle-aged women and explained the influential factors. Methods: This cross-sectional study with a sequential mixed method approach was conducted on 483 middle-age women selected through cluster random sampling in Yazd, Iran. Data were obtained by a research made questionnaire and analyzed with descriptive statistics and performing Pearson product-moment correlation, Student’s t-test, and One-way ANOVA tests, using SPSS version 16. In the second phase of the study, qualitative, semi-structured interviews were performed and data were analyzed through content analysis. Results: The majority of the subjects had never been screened for cancer through mammogram (87.7%, Pap test (64.2%, or fecal occult blood test (FOBT (89.8%. Educational level, employment status, perceived adequacy of income, perceived health status, and the number of children were significantly associated with breast and colon cancer screening practice. Qualitative data showed that lack of knowledge, the cost of screening exams, lack of financial independence, negligence of spouse, fear of cancer, embarrassment, and belief in destiny were the main reasons for non-adherence to cancer screening tests. In addition, knowledge and observing cancer in acquaintances and relatives were the main motivators of cancer screening. Conclusion: Middle-aged housewives, as well as women with low educational level and income were the most vulnerable groups, who did not adhere to cancer screening.

Analysis of the middle ear with fetal MRI has not been previously reported. To show the contribution of fetal MRI to middle ear imaging. The tympanic cavity was evaluated in 108 fetal cerebral MRI examinations (facial and/or cerebral malformation excluded) and in two cases, one of Treacher Collins syndrome (case 1) and the other of oculo-auriculo-vertebral (OUV) spectrum (case 2) with middle ear hypoplasia identified by MRI at 27 and 36 weeks' gestation, respectively. In all 108 fetuses (mean gestational age 32.5 weeks), the tympanic cavity and T2 hypointensity related to the ossicles were well visualised on both sides. Case 1 had micro/retrognathia and bilateral external ear deformity and case 2 had retrognathism with a left low-set and deformed ear. MRI made it possible to recognize the marked hypoplasia of the tympanic cavity, which was bilateral in case 1 and unilateral in case 2. Both syndromes are characterized by craniofacial abnormalities including middle ear hypoplasia, which cannot be diagnosed with US. The middle ear cavity can be visualized with fetal MRI. We emphasize the use of this imaging modality in the diagnosis of middle ear hypoplasia. (orig.)

A middle layer solution to support ACID properties for NoSQL databases

Ayman E. Lotfy

2016-01-01

Full Text Available The main objective of this paper is to keep the strengths of RDBMSs as consistency and ACID properties and at the same time providing the benefits that inspired the NoSQL movement through a middle layer. The proposed middle layer uses a four phase commit protocol to ensure: the use of recent data, the use of the Pessimistic technique to forbid others dealing with data while it is used and the data updates residing in many locations to avoid the loss of data and disappointment. This mechanism is required, especially in distributed database application NoSQL based environment, because allowing conflicting transactions to continue not only wastes constrained computing power and decreases bandwidth, but also exacerbates conflicts. The middle layer keeps tracking all running transactions and manages with other layers the execution of concurrent transactions. This solution will help increase both of the scalability, and throughput. Finally, the experimental results show that the throughput of the system improves on increasing the number of middle layers in scenarios and the amount of updates to read in a transaction increases. Also the data are consistent with executing many transactions related to each other through updating the same data. The scalability and availability of the system is not affected while ensuring strict consistency.

Bamberger, Yael M.; Cahill, Clara S.

2013-04-01

This study deals with engineering education in the middle-school level. Its focus is instructors' concerns in teaching design, as well as scaffolding strategies that can help teachers deal with these concerns. Through participatory action research, nine instructors engaged in a process of development and instruction of a curriculum about energy along with engineering design. A 50-h curriculum was piloted during a summer camp for 38 middle-school students. Data was collected through instructors' materials: observation field notes, daily reflections and post-camp discussions. In addition, students' artifacts and planning graphical models were collected in order to explore how instructors' concerns were aligned with students' learning. Findings indicate three main tensions that reflect instructors' main concerns: how to provide sufficient scaffolding yet encourage creativity, how to scaffold hands-on experiences that promote mindful planning, and how to scaffold students' modeling practices. Pedagogical strategies for teaching design that developed through this work are described, as well as the ways they address the National Research Council (A framework for K-12 science education: practices, crosscutting concepts, and core ideas. National Academies Press, Washington, DC, 2011) core ideas of engineering education and the International Technological Literacy standards (ITEA in Standards for technological literacy, 3rd edn.

The most noticeable characteristic of Daehan Hospital is that it was designed and constructed not by Korean engineers but by Japanese engineers. Therefore, Daehan Hospital was influenced by Japanese early modern medical facility, and Japanese engineers modeled Daehan Hospital main building on Tokyo Medical School main building which was constructed in 1876 as the first national medical school and hospital. The architectural type of Tokyo Medical School main building was a typical school architecture in early Japanese modern period which had a middle corridor and a pseudo Western-style tower, but Tokyo Medical School main building became the model of a medical facility as the symbol of the medical department in Tokyo Imperial University. This was the introduction and transplantation process of Japanese modern ‘model’ like as other modern systems and technologies during the Korean modern transition period. However, unlike Tokyo Medical School main building, Daehan Hospital main building was constructed not as a wooden building but as a masonry building.

Rescuing Middle School Astronomy

Science.gov (United States)

Mayo, L. A.; Janney, D.

2010-12-01

There is a crisis in education at the middle school level (Spellings, 2006). Recent studies point to large disparities in middle school performance in schools with high minority populations. The largest disparities exist in areas of math and science. Astronomy has a universal appeal for K-12 students but is rarely taught at the middle school level. When it is taught at all it is usually taught in isolation with few references in other classes such as other sciences (e.g. physics, biology, and chemistry), math, history, geography, music, art, or English. The problem is greatest in our most challenged school districts. With scores in reading and math below national averages in these schools and with most state achievement tests ignoring subjects like astronomy, there is little room in the school day to teach about the world outside our atmosphere. Add to this the exceedingly minimal training and education in astronomy that most middle school teachers have and it is a rare school that includes any astronomy teaching at all. In this presentation, we show how to develop and offer an astronomy education training program for middle school teachers encompassing a wide range of educational disciplines that are frequently taught at the middle school level. The prototype for this program was developed and launched in two of the most challenged and diverse school systems in the country; D.C. Public Schools, and Montgomery County (MD) Public Schools.

Full Text Available Hearing loss is becoming more common in the society living in cities with lot of background noise around, and frequent use of gadgets like mobile phones, MP3s, and IPods are adding to the problem. The loss may involve the conductive or perceptive pathway. Majority of the patients with conductive hearing loss will revert back to normal hearing levels with medical and/or surgical treatment. However, in sensorineural hearing loss, many factors are involved in the management. Though traditionally hearing aids in various forms are the most commonly used modality in managing these patients, there are some drawbacks associated with them. Implantable middle ear amplifiers represent the most recent breakthrough in the management of hearing loss. Middle ear implants are surgically implanted electronic devices that aim to correct hearing loss by stimulating the ossicular chain or middle ear. Of late, they are also being used in the management of congenital conductive hearing loss and certain cases of chronic otitis media with residual hearing loss. The article aims to provide general information about the technology, indications and contraindications, selection of candidates, available systems, and advantages of middle ear implants. (MEI

Duplicated middle cerebral artery (DMCA) is an anomalous vessel arising from the internal carotid artery. The incidence DMCA is relatively law, and an association between this anomaly and cerebral aneurysms has been documented. There is a controversy whether DMCA may have perforating arteries. This is an important fact to consider in aneurysm surgery. We report the case of a 34-year-old black woman who suffered a subarachnoid hemorrhage and the angiography a left DMCA, and an aneurysm in an inferior branch of the main MCA. The DMCA and the MCA had perforating arteries. The aneurysm was clipped without complications. The observation of perforating arteries in our patient confirms that the DMCA may have perforating arteries. This is very important to be considered in cerebral aneurysms surgery. Moreover, the DMCA may potentially serve as a collateral blood supply to the MCA territory in cases of MCA occlusion. PMID:22140405

Structure and function of the mammalian middle ear. I: Large middle ears in small desert mammals.

Mason, Matthew J

2016-02-01

Many species of small desert mammals are known to have expanded auditory bullae. The ears of gerbils and heteromyids have been well described, but much less is known about the middle ear anatomy of other desert mammals. In this study, the middle ears of three gerbils (Meriones, Desmodillus and Gerbillurus), two jerboas (Jaculus) and two sengis (elephant-shrews: Macroscelides and Elephantulus) were examined and compared, using micro-computed tomography and light microscopy. Middle ear cavity expansion has occurred in members of all three groups, apparently in association with an essentially 'freely mobile' ossicular morphology and the development of bony tubes for the middle ear arteries. Cavity expansion can occur in different ways, resulting in different subcavity patterns even between different species of gerbils. Having enlarged middle ear cavities aids low-frequency audition, and several adaptive advantages of low-frequency hearing to small desert mammals have been proposed. However, while Macroscelides was found here to have middle ear cavities so large that together they exceed brain volume, the bullae of Elephantulus are considerably smaller. Why middle ear cavities are enlarged in some desert species but not others remains unclear, but it may relate to microhabitat. © 2015 Anatomical Society.

In Phase 1 of the 'Feasibility Study on Commercialized Fast Reactor Cycle Systems (F/S)', an advanced loop type reactor has been selected as a promising concept of sodium-cooled middle-scale modular reactor, which has a possibility to fulfill the design requirements of the F/S. This report summarizes the results of the design study on the sodium-cooled middle-scale modular reactor performed in JFY2002, which is the second year of Phase 2. The construction cost of the sodium-cooled middle-scale modular reactor, which has been constructed in JFY2002, was almost achieved the economical goal. But its achievability was not sufficient to accept the concept. In order to reduce the construction cost, the plant concept has been re-constructed based on the 50 MWe plant studied in JFY2002. After that, fundamental specifications of main systems and components for the new concept have been set, and critical subjects have been examined and evaluated. In addition, in order to achieve the further cost reduction, the plant with simplified secondary system, the plant with electric magnetic pump in secondary system, and the fuel handling system are examined and evaluated. As a result of this study, the plant concept of the sodium-cooled middle-scale modular reactor has been constructed, which has a prospect to satisfy the economic goal (construction cost: less than 200,000 yens/kWe, etc.) and has a prospect to solve the critical subjects. From now on, reflecting the results of elemental experiments, the preliminary conceptual design of this plant will be preceded toward the selection for narrowing down candidate concepts at the end of Phase 2.

Full Text Available The main purpose of this article is to analyze the main ideas of the Medieval Period authors in Europe and in Russia, in terms of identifying the most important theses of this historical period for the formation and development of the ideas of gender psychology. It is being considered the role of Christianity and the emergence of the women's education issue in the formation of gender stereotypes. In this article the Middle Ages period is being considered as a separate historical phase for the basic ideas formation in the gender psychology, which is a new approach to the history of gender science. To estimate medieval texts - European and Russian, the method of qualitative content analysis is used, by means of which the most relevant to the period ideas associated with the sexes are identified. For Europe, it inter-sexual features, for Russia - different behavioral requirements of the society associated with sexes. Conclusions contain ideas of the Middle Ages in Europe and in Russia that are relevant to the development and establishment of gender psychology. In Europe: the continuation of the ancient thesis of the initial androgyny of a human being; impact of the woman's education on her ability for development; consideration of sexuality as sinful; the issue of women's emancipation, the declining value of the large numerous families despite of a ban on interference in the reproductive cycle in the middle of the Medieval period. In Russia: the perception of inter-sexual characteristics as defined by the God; unconditional obedience of a woman to her husband; androgyny in the distribution of the farmers’ responsibilities.Objective: To analyze the main ideas of the authors of the Middle Ages in Europe and in Russia, in terms of identifying the significant theses of this historical period for the formation and development of the ideas of the gender psychology.Method of the research work: A qualitative content analysis of the texts by the authors

Conclusions: Our survey provides a contemporary snapshot of the ME thoracic anesthetic practice. PMID:23162388

Adrenarche and middle childhood.

Science.gov (United States)

Campbell, Benjamin C

2011-09-01

Middle childhood, the period from 6 to 12 years of age, is defined socially by increasing autonomy and emotional regulation, somatically by the development of anatomical structures for subsistence, and endocrinologically by adrenarche, the adrenal production of dehydroepiandrosterone (DHEA). Here I suggest that DHEA plays a key role in the coordinated development of the brain and body beginning with middle childhood, via energetic allocation. I argue that with adrenarche, increasing levels of circulating DHEA act to down-regulate the release of glucose into circulation and hence limit the supply of glucose which is needed by the brain for synaptogenesis. Furthermore, I suggest the antioxidant properties of DHEA may be important in maintaining synaptic plasticity throughout middle childhood within slow-developing areas of the cortex, including the insula, thamalus, and anterior cingulate cortex. In addition, DHEA may play a role in the development of body odor as a reliable social signal of behavioral changes associated with middle childhood.

A New Perspective in the Middle East: A Comprehensive Approach To The Us-Iran Relations in the Region

2016-12-01

Full Text Available This paper discusses the significance of the cooperation between the United States and Iran for the Middle East region. It will be argued that despite the political and ideological conflicts between the U.S. and Iran, reaching a “point by point” agreement would best help to resolve Middle East predicaments, especially the Islamic terrorism. To achieve this, the following pages examine the historical background of issues such as terrorism in the Middle East. This paper also focuses on two main paths to support the better U.S.-Iran cooperation, if not talking about relations at all. First, the theory of “point by point” approach helps both countries to tackle tough agendas and overcome the predicaments in the Middle East. Second, to reach the desired cooperation between these two countries, both the U.S. and Iran need to overcome their own internal constraints as well as the external constrains imposed by other countries. This paper takes an historical and theoretical approach to reveal the two countries’ common interests in the Middle East. The general thesis argues that the Middle East’s security requires the United States and Iran to develop a diplomatic and military cooperation.

The concept of middle power. The cases of Spain and Mexico

Directory of Open Access Journals (Sweden)

Jordi Palou

1993-07-01

Full Text Available The concept of power refers to a certain capacity of particular States to impose their will on others and make them act in a certain way. In order to measure this influence and establish a hierarchy process, recourse has been made to various geographical, demographic,economic, military and political indicators. In the case of middle powers one ought also to add that the will of the State is of maximum importance in terms of how it acts as a middle power.From a list of 15 middle powers drawn up on criteria used in preceeding lists, the Spanish and Mexican cases are analyzed, (both of which are considered not incorrectly as middle powers for various reasons which share certain similarities ; for their geostrategicsituation, for their level of economic development inferior to that of their neighbours, because they have served as models (economic development and democratic transition respectively and also because both have offered themselves as “bridges”. Among the differences can be highlighted that which seperates those powers orientated towards the developed world and those which accept their belonging to the third world.At a moment in which States have multiplied themselves and in which the withdrawal of colonial powers has led to a certain withdrawal of those superpower pressures, the possibility that some middle powers can consolidate in some areas of influence is opened. The economic situation also plays a fundamental role and in this sense the crisis can be an important limitation. In any case the concept of middle power is indivisible from a specific international context and at present its main scope for action is the north-south confrontation with the economic factor at the forefront. Those compromises with which it has entered with certain organizations of economic integration can also reduce its margin for manoeuvre. Finally, serious doubts are cast regarding the possibility of a concerted action by the middle powers in order to

Nowadays most plant textiles used for clothing and household are made of cotton and viscose. Before the 19th century however, plant textiles were mainly made from locally available raw materials, in Scandinavia these were: nettle, hemp and flax. It is generally believed that in Viking and early Middle Ages Scandinavia hemp was used only for coarse textiles (i.e. rope and sailcloth). Here we present an investigation of 10 Scandinavian plant fibre textiles from the Viking and Early Middle Ages, believed to be locally produced. Up till now they were all believed to be made of flax. We show that 4 textiles, including two pieces of the famous Överhogdal Viking wall-hanging are in fact made with hemp (in three cases hemp and flax are mixed). This indicates that hemp was important, not only for coarse but also for fine textile production in Viking and Early Middle Ages in Scandinavia.

Middle Eastern and North African countries are undergoing nutrition transition, a transition which is associated with an increased burden of non-communicable diseases. This necessitates the evaluation of dietary patterns in these regions. The present study aimed to assess changes in dietary patterns in Middle Eastern and North African countries between 1961 and 2007. Availability of energy and fifteen main food items during 1961-2007 was examined using FAO food balance sheets from the FAOSTAT database. Fifteen countries including nine in the Middle East and six in North Africa were selected and the average availability of total energy and different food items in these regions were compared. Over the 47 years studied, energy and food availability (apart from animal fats and alcoholic beverages) has increased in the Middle East and North Africa. In both regions the proportion of energy derived from meat and vegetable oils has increased significantly while that from cereals decreased significantly. In addition, the proportion of energy from milk and dairy products and vegetables has shown an ascending trend in North Africa while the proportion of energy from fruits has shown a descending trend in the Middle East. The study results reveal an unfavourable trend towards a Westernized diet in the Middle East and, to a certain extent, in North Africa. Tailored nutritional education encouraging healthy eating for prevention of the burden of chronic diseases in these countries seems essential.

The penetration of Middle east gas in Europe will be limited at middle term

International Nuclear Information System (INIS)

Anon.

1995-01-01

The European gas demand has progressed about 4% by year from 1985 to 1994. A growth of 3% is expected for future. So, it seems that Middle East could take a place on gas European market. But with competition of North Africa or ex-USSR, the price of transport or the investment for a gas pipeline, the contribution of Middle East gas to European supply will stay limited in a middle term. Perspectives could be very different if political stability of Algeria or ex-USSR was no more assured

Positive response of Indian summer rainfall to Middle East dust

KAUST Repository

Jin, Qinjian

2014-06-02

Using observational and reanalyses data, we investigated the impact of dust aerosols over the Middle East and the Arabian Sea (AS) on the Indian summer monsoon (ISM) rainfall. Satellite and aerosol reanalysis data show extremely heavy aerosol loading, mainly mineral dust, over the Middle East and AS during the ISM season. Multivariate empirical orthogonal function analyses suggest an aerosol-monsoon connection. This connection may be attributed to dust-induced atmospheric heating centered over the Iranian Plateau (IP), which enhances the meridional thermal contrast and strengthens the ISM circulation and rainfall. The enhanced circulation further transports more dust to the AS and IP, heating the atmosphere (positive feedback). The aerosols over the AS and the Arabian Peninsula have a significant correlation with rainfall over central and eastern India about 2 weeks later. This finding highlights the nonlocal radiative effect of dust on the ISM circulation and rainfall and may improve ISM rainfall forecasts. © 2014. American Geophysical Union. All Rights Reserved.

Predictive simulation of the solvent extraction of aromatics from middle distillates

Energy Technology Data Exchange (ETDEWEB)

Rahman, M.

1983-03-01

This work describes a predictive method for calculating liquid-liquid aromatics extracton from a middle distillate. Group contribution models of the ASOG and UNIFAC type are investigated. Four vapor-liquid equilibria (VLE) on the binary of naphthalene - n-dodecane, naphthalene - n-tetradecane, phenanthrene - n-hexadecane and transdecaline - benzene and two solid-liquid equilibria (SLE) on the binary of naphthalene - n-hexadecane and phenanthrene - n-hexadecane were measured. Dimethylformamide (DMF) was chosen as an extracting solvent. Three liquid-liquid equilibria (LLE) on the binary of DMF with n-hexadecane, n-tetradecane or trans + cis decaline and six ternary LLE on the mixture of DMF - n-hexadecane with octyl benzene, tetralin, 1 methyl naphthalene, phenanthrene or benzothiophene and on the mixture of decaline - DMF with benzothiophene were also measured. The parameters of the models are based mainly on the data for the systems composed by hydrocarbons with a 10-20 carbon number. The data for VLE, SLE and the infinite dilution activity coefficient (17-245/sup 0/C) were used to calculate interaction parameters between hydrocarbon groups, and LLE data (20-80/sup 0/C) for interaction parameters of dimethylformamide - hydrocarbon groups. The validity of the models for predicting the LLE of DMF - hydrocarbon multicomponent mixture (8 components) was verified. Middle distillate representation is based on mass spectrometric and gas chromatographic analysis and on limited data on middle distillate - DMF LLE. Two models for middle-distillate representation were investigated. It is shown that the performance of ASOG and UNIFAC are sufficiently valid for representing of basic data and for the predicting the solvent extraction of aromatics from middle distillates. The method investigated can be useful for the rapid preliminary study of extraction processes.

A NEW LEPIDOSAUROMORPH REPTILE FROM THE MIDDLE TRIASSIC OF THE DOLOMITES (NORTHERN ITALY

Directory of Open Access Journals (Sweden)

SILVIO RENESTO

2003-11-01

Full Text Available A new genus and species of diapsid reptile is described. The specimen was collected from the Anisian (Middle Triassic succession of Monte Prà della Vacca (Kühwiesenkopf in the Dolomites of Braies (Bolzano/Bozen, Northern Italy. Despite being incomplete, the specimen shows enough characters to allow its placement within Lepidosauriformes, close to the Middle Jurassic genus Marmoretta. The importance of this find lies in the great rarity of lepidosauriforms of Anisian age, an epoch approximating the appearance of the first members of the true Lepidosauria (rhyncocephalians and squamates. The new genus may thus add knowledge to the diversity of early lepidosaurians. Some characters of the skeleton, mainly of the forelimb, suggest a terrestrial, perhaps arboreal life style.

A method of calculating liquid-liquid aromatics extraction of a middle distillate is described. The group contribution models of the ASOG and UNIFAC type are investigated. Four vapor liquid equilibrium (VLE), two solid-liquid equilibrium (SLE), three binary and six ternary liquid-liquid equilibrium (LLE) have been measured. The parameters of the models are based mainly on the data of the systems having 10-20 carbon number. VLE, SLE, and infinite dilution activity coefficient data (17-245/sup 0/C) have been used for calculating interaction parameters between hydrocarbon groups and LLE data (20-80/sup 0/C) for interaction parameters of dimethylformamide-hydrocarbon groups. Middle distillate representation is based on mass spectrometric and gas chromatographic analysis and on limited data of middle distillate-DMF liquid-liquid equilibrium. It is shown that the performance of ASOG and UNIFAC models are sufficiently valid in representation of data base and in extraction calculations. Considering the predictive character and the rapidity of its application this method can be useful in the preliminary study of extraction processes. 34 references, 2 figures, 10 tables.

Full Text Available This paper aims to assess the role of middle class in Indonesia’s democracy, with the particular focus of the last Indonesian Presidential election. This study uses econometric analyses to assess preferences of middle class in presidential election by exploring data at district/city and provincial. The main finding in this study strongly suggests that religious and personality are still important elements under the race of Indonesia president. This study also found that different group of middle class has different attitudes in selecting the presidential candidate and the upper group of middle class is more likely to select Joko Widodo. Finally, a fragile middle class and a relatively high number of abstainers could be a barrier toward more substantive democracy. Abstrak Makalah ini bertujuan untuk menganalisis peran kelompok kelas menengah dalam proses demokrasi di Indonesia, secara khusus peran mereka difokuskan pada hasil pemilihan presiden yang terakhir. Studi ini menggunakan pendekatan ekonometrik untuk mengalisis preferensi kelompok kelas menengah dalam memilih calon presiden, dengan melakukan eksplorasi data pada tingkat kabupaten/kota dan provinsi. Hasil studi menunjukkan, agama dan personalitas calon presiden menjadi faktor penting dalam pertarungan pemilihan presiden. Studi ini juga menunjukkan, berbagai kelompok dalam kelas menengah memiliki preferensi yang berbeda dalam memilih kandidat presiden dan kelompok kelas menengah atas cenderung memilih Joko Widodo. Akhirnya, kelas menengah yang rentan dan tingginya kelompok yang abstain, akan menjadi hambatan untuk menuju demokrasi yang lebih substantif.

The objective of this study is to illustrate prevention strategies and management of vascular complications from the jugular bulb (JB) and internal carotid artery (ICA) during middle ear surgery or cochlear implantation. The study design is retrospective case series. The setting is tertiary referral university hospital. Patients were included if presented pre- or intraoperative evidence of high-risk anatomical anomalies of ICA or JB during middle ear or cochlear implant surgery, intraoperative vascular injury, or revision surgery after the previous iatrogenic vascular lesions. The main outcome measures are surgical outcomes and complications rate. Ten subjects were identified: three underwent cochlear implant surgery and seven underwent middle ear surgery. Among the cochlear implant patients, two presented with anomalies of the JB impeding access to the cochlear lumen and one underwent revision surgery for incorrect positioning of the array in the carotid canal. Subtotal petrosectomy was performed in all cases. Anomalies of the JB were preoperatively identified in two patients with attic and external auditory canal cholesteatoma, respectively. In a patient, a high and dehiscent JB was found during myringoplasty, while another underwent revision surgery after iatrogenic injury of the JB. A dehiscent ICA complicated middle ear effusion in one case, while in another case, a carotid aneurysm determined a cholesterol granuloma. Rupture of a pseudoaneurysm of the ICA occurred in a child during second-stage surgery and required permanent balloon occlusion without neurological complications. Knowledge of normal anatomy and its variants and preoperative imaging are the basis for prevention of vascular complications during middle ear or cochlear implant surgery.

Middle manager role and contribution towards the competitive intelligence process: A case of Irish subsidiaries

Willie Chinyamurindi

2016-07-01

Full Text Available Background: Calls have been made especially during a period of global competition and economic austerity for research that focuses on how competitive intelligence (CI is actually generated within organisations. Objectives: The aim of this study was to understand the views and experiences of middle managers with regard to their role and contribution towards the CI process within Irish subsidiaries of the Multinational Corporation (MNC. Method: The study adopts a qualitative approach using the semi-structured interview technique to generate narratives and themes around how CI is generated using a sample of 15 middle managers drawn from five participating Irish subsidiaries. Results: Based on the analysis of the narratives of the middle managers, three main themes emerged as findings. Firstly, the process of gathering CI was facilitated by the reliance on internal and external tools. Secondly, information gathered from the use of such tools was then communicated by middle managers to top managers to inform the making of strategic decisions. Thus, (and thirdly, middle managers were found to occupy an important role not only through the execution of their management duties but by extending this influence towards the generation of information deemed to affect the competitive position of not just the subsidiary but also the parent company. Conclusion: The study concludes by focusing on the implications and recommendations based on the three themes drawn from the empirical data.

Economic analysis of milk production and consumption in the Middle East and North Africa

Directory of Open Access Journals (Sweden)

Mansoor Maitah

2012-01-01

Full Text Available Milk products are considered as the essential food commodities for humans. Milk products contain essential elements for the human body such as protein, glucose, minerals and vitamins. Moreover, milk is considered the cheapest source of animal protein, an important resource for some related transformation industries and provides employment opportunities for a large number of small producers in both rural and urban areas. The aim of this paper is to analyze the factors which determine the supply and demand for liquid milk (henceforth milk in the Middle East and North Africa in order to point out the main problems and constraints obstructing the milk production in this region. The research also attempts to understand the drivers for the development in milk production in the Middle East and North Africa.Total milk production in the Middle East and North Africa increased from about 12.57 million tons in 1990 to about 25.18 millions tons in 2008. This paper attempts to identify the factors which influence the effectiveness of production, consumption and foreign trade of milk in the Middle East and North Africa. The most important factors affecting consumption is the population, per capita income and produced quantity where a 1% increase in all of them results in increasing the quantity consumed by 1.3%, 2.86% and 0.611%, respectively. Milk sector provides employment opportunities for more than 25% of the working force in some Middle East and North Africa countries.

Creating regional consensus for starting school later: a physician-driven approach in southern Maine.

Science.gov (United States)

Collins, Tracey Ann; Indorf, Christopher; Klak, Thomas

2017-12-01

In April 2016, several contiguous school districts and an independent high school academy in southern Maine voted simultaneously to start school later, beginning with the 2016-17 academic year. They became Maine's first school districts to implement the American Academy of Pediatrics' 1 and the American Medical Association's 2 health policy recommendations that middle and high schools should not start before 8:30 AM. Local physicians' presentations to school staff and parents on the medical evidence of the health benefits of a later start solidified early consensus. The action required special permission from the Maine Municipal Association to hold a joint school board vote, impacted approximately 6500 students across the region, resulted in no increase in busing costs, and took 8 months to implement after the first formal school board discussions.

Full Text Available The research of the middle class formation process in the Republic of Moldova is of majorimportance, as it allows to identify its main elements and the possibilities of formation under the currentconditions. The article presents the results of the sociological study on the premises of the middle classformation in the Republic of Moldova, carried out during June-September 2016. The results from thisstudy show that the society is distributed in 6 social strata that vary by socio-professional status, level ofeducation and level of wellbeing. The status inconsistency and low level of status crystallisation arecharacteristics for all strata within the conditions of dysfunctionality of logical chain: education-socialoccupational status-welfare. As per the research, the process of classes’ formation is just at the initialstage in the Republic of Moldova. The analysis of the social strata in terms of middle class criteria: highsocio professional status, high education level, high level of welfare, shows some prospects of formationof the middle class in the upper strata within the following conditions: development of wage policies;reforming tax policies by promoting the progressive taxation of income; ensuring equitable distribution ofwages according to work; elimination of corruption in power structures; improving legislation; ensuringaccess of the population to decision – making process; creating favourable conditions for development ofsmall and medium business; development of a transparent environment for the market economy; guarantyof fair conditions to population to ensure access to education and health services.

1982-03-01

A 64-year-old woman had received radiotherapy, following surgery of a chromophobe pituitary adenoma. Six years after irradiation she began to complain of headache and dementia. Right vertebrogram demonstrated a right temporal mass lesion, stenosis and dilatation of middle cerebral artery and posterior communicating artery in the field of irradiation. CT scan showed the irregular low density area at the right temporal region, and the irregular enhancement after an intravenous injection of contrast medium was seen at the small part of affected area. From these findings, radiation necrosis at the right temporal lobe was diagnosed. Reports of vascular changes of the main cerebral arteries due to radiation are rare.

The importance of a child’s education in middle class families [Znaczenie edukacji dziecka w rodzinie z klasy średniej

Full Text Available The following study proves the thesis that in present-day Polish conditions children’s education does not depend on their intellectual capacity, but it rather depends on the financial background, the social and cultural capital and parent’s social class. In addition, family status and family members contribute to a child’s position in a specific social space. At the beginning I would like to indicate Pierre Bourdieu’s theory as the main basis upon which this study is based, afterwards I present selected conceptions and definitions of the middle class. In the next part I describe the research concerning middle class children’s standard of education. This is the background on which I present the program of self-study and its results. The materials presented show the value which is assigned by parents to their children, their upbringing, and education. In addition, it enables one to analyse the mentality of this specific group of parents and the educational patterns which they use to support their children. The research results and the opinions described in the text lead us to assume that parents from the middle class provide their children with practically unlimited support, which will help them in the future to reconstruct their social status. In general, the main goal of parents from the middle class is to create life chances for their children, so they can succeed in life. The analysis proves that middle class children can count on financial, material, psychological, and public support from their parents. In my paper I elaborate on how much importance middle class parents attach to their children’s education as well as what their expectations and plans related to education are

The inner part of cochlear implant is inserted into inner ear during surgery through mastoid and middle ear. It is a classical method, used in the majority cochlear centers in the world. This is not a suitable method in case of chronic otitis media and middle ear malformation. In these cases Colletti proposed the middle fossa approach and cochlear implant insertion omitting middle ear structures. In patient with bilateral chronic otitis media underwent a few ears operations without obtaining dry postoperative cavity. Cochlear implantation through the middle fossa approach was performed in this patient. The bone fenster was cut, temporal lobe was bent and petrosus pyramid upper surface was exposed. When the superficial petrosal greater nerve, facial nerve and arcuate eminence were localised, the cochlear was open in the basal turn and electrode were inserted. The patient achieves good results in the postoperative speech rehabilitation. It confirmed Colletti tesis that deeper electrode insertion in the cochlear implantation through the middle fossa approach enable use of low and middle frequencies, which are very important in speech understanding.

International migration to middle-income countries is increasing and its health consequences, in particular increasing transmission rates of tuberculosis (TB), deserve consideration. Migration and TB are a matter of concern in high-income countries and targeted screening of migrants for active and latent TB infection is a main strategy to manage risk and minimize transmission. In this paper, we discuss some aspects of TB control and migration in the context of middle-income countries, together with the prospect of responding with equitable and comprehensive policies. TB rates in middle-income countries remain disproportionally high among the poorest and most vulnerable groups in large cities where most migrant populations are concentrated. Policies that tackle migrant TB in high-income countries may be inadequate for middle-income countries because of their different socio-economic and cultural scenarios. Strategies to control TB in these settings must take into account the characteristics of middle-income countries and the complexity of TB as a disease of poverty. Intersectoral policies of social protection such as cash-transfer programs help reducing poverty and improving health in vulnerable populations. We address the development of new approaches to improve well-established strategies including contact tracing and active and latent TB screening as an 'add on' to the existing health care guidelines of conditional cash transfer programs. In addition, we discuss how it might improve health and welfare among both poor migrants and locally-born populations. Authorities from middle-income countries should recognise that migrants are a vulnerable social group and promote cooperation efforts between sending and receiving countries for mitigation of poverty and prevention of disease in this group. Middle-income countries have long sent migrants overseas. However, the influx of large migrant populations into their societies is relatively new and a growing phenomenon and

Convergence in Sleep Time Accomplished? Gender Gap in Sleep Time for Middle-Aged Adults in Korea.

2018-04-19

Although the gender gap in sleep time has narrowed significantly in the last decade, middle-aged women between ages 35 and 60 still sleep less than their male counterparts in Korea. This study examines and provides evidence for factors contributing to the gender gap in this age group. Using Korean Time Use Survey (KTUS) data from 2004, 2009 and 2014, we find that middle-aged women’s difficulty in managing work-life balance and traditional role expectations placed upon women are the main causes of the gender gap in sleep time. The decomposition analysis reveals that the improved socioeconomic status and recent changes in familial expectations for women may have helped them sleep more than in the past. However, there remain fundamental differences in attitude and time use patterns between men and women that prevent middle-aged women from getting the same amount of sleep.

The reactors of melted salts called Molten Salt Fast Reactor (MSFR), have seen a resurgence of interest in the last decade. This design is one of the six proposed for the IV generation reactors. The most active development was in the middle of 1950 and principles of 1970 in the Oak Ridge National Laboratories (ORNL). In this work the mathematician modeling of the main components in the primary and secondary circuits of a M SR is presented. In particular the dynamics of the heat exchanger is analyzed and they are considered several materials to optimize the system thermodynamically. (Author)

Middle managers have received little attention in extant health services research, yet they may have a key role in healthcare innovation implementation. The gap between evidence of effective care and practice may be attributed in part to poor healthcare innovation implementation. Investigating middle managers' role in healthcare innovation implementation may reveal an opportunity for improvement. In this paper, we present a theory of middle managers' role in healthcare innovation implementation to fill the gap in the literature and to stimulate research that empirically examines middle managers' influence on innovation implementation in healthcare organizations. Extant healthcare innovation implementation research has primarily focused on the roles of physicians and top managers. Largely overlooked is the role of middle managers. We suggest that middle managers influence healthcare innovation implementation by diffusing information, synthesizing information, mediating between strategy and day-to-day activities, and selling innovation implementation. Teamwork designs have become popular in healthcare organizations. Because middle managers oversee these team initiatives, their potential to influence innovation implementation has grown. Future research should investigate middle managers' role in healthcare innovation implementation. Findings may aid top managers in leveraging middle managers' influence to improve the effectiveness of healthcare innovation implementation.

Full Text Available Blunt chest trauma resulting in rupture of a main bronchus is rare and probably have a high prehospital mortality.These injuries are often fatal because of respiratory distress and the high frequency of associated multiple organ injuries. A six-year-old boy was admitted our clinic due to blunt chest trauma. The tube thoracostomy was performed for the right pneumothorax at another surgical center. He was referred to our clinic due to inadequate expansion of the lung. On the physical examination, there was middle intercostal retraction, cyanosis and tachypnoea. The initial chest x-ray showed total pnemothorax on the right side and the hilum replaced by inferiorly. The rigid bronchoscopy was performed and the the rupture of main bronchus was seen. The sleeve upper lobectomy was performed. We aimed to emphasize the important of early diagnosis and treatment in the bronchial ruptures.

Based on the hourly TBB and cloud images of FY-2E, meteorological observation data, and NCEP reanalysis data with 1°×1° spatial resolution from May to October during 2005-2014, the climatic characteristics of mesoscale convective systems (MCS) over the middle reaches area of the Yellow River were analyzed, including mesoscale convective complex (MCC), persistent elongated convective systems (PECS), meso-βscale MCC (MβCCS) and Meso-βscale PECS (MβECS). The results are as follows: (1) MCS tended to occur over the middle and south of Gansu, the middle and south of Shanxi, the middle and north of Shaanxi, and the border of Shanxi, Shaanxi and Inner Mongolia. MCS over the middle reaches area of the Yellow River formed in May to October, and was easy to develop the mature in summer. MCC and MβECS were main MCS causing precipitation in summer. (2) The daily variation of MCS was obvious, and usually formed and matured in the afternoon and the evening to early morning of the next day. Most MCS generated fast and dissipated slowly, and were mainly move to the easterly and southeasterly, but the moving of round shape MCS was less than the elongated shape's. (3) The average TBB for the round shape MCS was lower than the elongated shape MCS. The development of MCC was most vigorous and strong, and it was the strongest in August, while that of MβECS wasn't obviously influenced by the seasonal change. The average eccentricity of the mature MCC and PECS over the middle reaches area of the Yellow River was greater than that in USA, and the former was greater than in the lower reaches area of the Yellow River, while the latter was smaller. (4) The characteristics of rainfall caused by MCS were complex over the middle reaches area of the Yellow River, and there were obvious regional difference. There was wider, stronger and longer precipitation when the multiple MCS merged. The rainfall in the center of cloud area was obviously greater than in other region of cloud area. The

2012-03-01

To understand transnational tobacco companies' (TTCs) practices in low and middle-income countries which serve to block tobacco-control policies and promote tobacco use. Systematic review of published research on tobacco industry activities to promote tobacco use and oppose tobacco-control policies in low and middle-income countries. TTCs' strategies used in low and middle-income countries followed four main themes-economic activity; marketing/promotion; political activity; and deceptive/manipulative activity. Economic activity, including foreign investment and smuggling, was used to enter new markets. Political activities included lobbying, offering voluntary self-regulatory codes, and mounting corporate social responsibility campaigns. Deceptive activities included manipulation of science and use of third-party allies to oppose smoke-free policies, delay other tobacco-control policies, and maintain support of policymakers and the public for a pro-tobacco industry policy environment. TTCs used tactics for marketing, advertising, and promoting their brands that were tailored to specific market environments. These activities included direct and indirect tactis, targeting particular populations, and introducing new tobacco products designed to limit marketing restrictions and taxes, maintain the social acceptability of tobacco use, and counter tobacco-control efforts. TTCs have used similar strategies in high-income countries as these being described in low and middle-income countries. As required by FCTC Article 5.3, to counter tobacco industry pressures and to implement effective tobacco-control policies, governments and health professionals in low and middle-income countries should fully understand TTCs practices and counter them.

After middle ear reconstruction using partial or total ossicular replacement prostheses (PORP/TORP), an air-bone gap (ABG) may persist because of prosthesis displacement or malposition. So far, CT of the temporal bone has played the main role in the diagnosis of reasons for postoperative insufficient ABG improvement. Recent experimental and clinical studies have evaluated flat panel CT (fpCT) as an alternative imaging technique that provides images with high isovolumetric resolution, fewer metal-induced artefacts and lower irradiation doses. One hundred and seven consecutive patients with chronic otitis media with or without cholesteatoma underwent reconstruction by PORP (n = 52) or TORP (n = 55). All subjects underwent preoperative and postoperative audiometric testing and postoperative fpCT. Statistical evaluation of all 107 patients as well as the sole sub-assembly groups (PORP or TORP) showed a highly significant correlation between hearing improvement and fpCT-determined prosthesis position. FpCT enables detailed postoperative information on patients with middle ear reconstruction. FpCT is a new imaging technique that provides immediate feedback on surgical results after reconstructive middle ear surgery. Specific parameters evaluated by fpCT may serve as a predictive tool for estimated postoperative hearing improvement. Therefore this imaging technique is suitable for postoperative quality control in reconstructive middle ear surgery. (orig.)

Quest for Middle East oil: the US versus the Asia-Pacific region

International Nuclear Information System (INIS)

Salameh, Mamdouh G.

2003-01-01

Two very powerful geopolitical factors will decisively determine whether the quest for Middle East oil (mainly Gulf oil) could enhance the global oil security or could lead to oil supply disruptions and also instability and conflict in the Asia-Pacific region. The two factors are the United States' growing dependence on oil imports from the Middle East and the Asia-Pacific region's thirst for oil and the increasingly likely Chinese dependence on oil from the region. The Asia-Pacific countries are increasingly growing concerned about their ability to supply enough oil to fuel future economic growth. The region's phenomenal economic growth up to July 1997 and its economic recovery since then, and its steadily rising energy needs lend urgency to the question of how the region would meet its considerable energy challenges. This paper will endeavour to analyze the impact of this growing dependence on Middle East oil, on global oil supplies, the price of oil and global oil security. It will argue that such dependence on a volatile region like the Middle East and the perception of scarcer energy resources in the Asia-Pacific region, have the potential to lead to conflict in both regions unless these issues are dealt with in geoeconomic rather than geostrategic terms. The paper will strongly express the view that potential conflicts can be resolved not by force but through markets and investment and also through the diversification of energy sources and the promotion of alternative energy development and use across the region

The archaeological works developed during the years 1996 in the site of Tafesa, 2005 in the 12 de Octubre Metro Station site and 2006 in the confluence of the Butarque Stream (Villaverde-Barrio de Butarque site) located south of the Madrid City (Spain), have provided new lithic assemblages. These assemblages have been stratigraphic ally contextualized in the Pleistocene deposits of the Lower Manzanares river valley within the so-called Manzanares Complex Terrace (TCMZ). This fluvial terrace constitutes an anomalous thickened (20-15m) deposit at {+-}22-16m above the present river thalweg mainly developed along the right (southern) valley margin. This fluvial level has been traditionally considered of middle Pleistocene age on the basis of the acheulian lithics and faunal assemblages typically located within its lower stratigraphic layers. Certainly, the Tafesa is a fluvial terrace site at {+-}22 m with acheulian industry and middle Pleistocene faunal remains at its lower sedimentary sequence. However, the upper sedimentary levels of this same terrace in the 12 de Octubre y Villaverde-Butarque sites throw lithic assemblages of the lower and upper Paleolithic belonging to upper Pleistocene, as suggested by the available set of TL and OSL dates for the zone. The analyses developed in this study indicate that the development of this thickened fluvial terrace started during the end of the middle Pleistocene, but also comprise the whole Oxygen Isotopic Stage OIS 5 during the upper Pleistocene.

In-line estimation of sulfur and nitrogen contents during hydrotreating of middle distillates

Directory of Open Access Journals (Sweden)

M. E. Pacheco

2009-12-01

Full Text Available The main objective of this work is analyzing whether it is possible to develop an empirical correlation for in-line estimation of the sulfur and nitrogen contents of the middle distillates Hydrotreating (HDT products for control purposes. Correlations are based only on readily available in-line information of specific gravity variation between feedstock and products, without considering any piece of information about the kinetic behavior of the catalyst. Experimental data were obtained in pilot plants under operating conditions that are representative of refinery operations. Results indicate that the removal of nitrogen and sulfur compounds during middle distillates HDT can be monitored in-line in real time, based on the available measurements of specific gravity. This allows for development and implementation of advanced in-line procedures for monitoring and control of the HDT process in real time.

Kicker, D.C.; Martin, E.R.; Brechtel, C.E.; Stone, C.A.; Kessel, D.S.

1997-07-01

Geotechnical characterization of the Main Drift of the Exploratory Studies Facility was based on borehole data collected in site characterization drilling and on scanline rock mass quality data collected during the excavation of the North Ramp. The Main Drift is the planned 3,131-m near-horizontal tunnel to be excavated at the potential repository horizon for the Yucca Mountain Site Characterization Project. Main Drift borehole data consisted of three holes--USW SD-7, SD-9, and SD-12--drilled along the tunnel alignment. In addition, boreholes USW UZ-14, NRG-6, and NRG-7/7A were used to supplement the database on subsurface rock conditions. Specific data summarized and presented included lithologic and rock structure core logs, rock mechanics laboratory testing, and rock mass quality indices. Cross sections with stratigraphic and thermal-mechanical units were also presented. Topics discussed in the report include geologic setting, geologic features of engineering and construction significance, anticipated ground conditions, and the range of required ground support. Rock structural and rock mass quality data have been developed for each 3-m interval of core in the middle nonlithophysal stratigraphic zone of the Topopah Spring Tuff Formation. The distribution of the rock mass quality data in all boreholes used to characterize the Main Drift was assumed to be representative of the variability of the rock mass conditions to be encountered in the Main Drift. Observations in the North Ramp tunnel have been used to project conditions in the lower lithophysal zone and in fault zones

The equatorial region has attracted many MAD studies mainly based on data of limited locations and resolutions. Established at NIEO are: (1) Climatology of the equatorial middle atmosphere (all of the mean zonal flow, the meridional and/or east-west circulations and the planetary/gravity waves are described based on massive, reliable data statistics); (2) Troposphere-stratosphere coupling at the equator (the candidate location of NIEO is just at the stratospheric fountain area where the tracers and waves are pumped up into the middle atmosphere); and (3) Mesosphere-thermosphere coupling at the equator; thermospheric superrotation, which may be caused either by ion drag or by tidal breaking, is examined in detail by observations covering a wide altitude range from the mesosphere through the thermosphere.

Iron in the Middle Devonian aquifer system and its removal at Võru County water treatment plants, Estonia

OpenAIRE

Mariina Hiiob; Enn Karro

2012-01-01

Groundwater abstracted from the Middle Devonian aquifer system is the main source of drinking water in South Estonia. High iron and manganese concentrations in groundwater are the greatest problems in this region. The total iron concentrations up to 16 mg L–1 are mainly caused by a high Fe2+ content in water, pointing to the dominance of reducing conditions in the aquifer system.

During early adolescence, most public school students undergo school transitions, and many students experience declines in academic performance and social-emotional well-being. Theories and empirical research have highlighted the importance of supportive school environments in promoting positive youth development during this period of transition. Despite this, little is known about the proximal social and developmental contexts of the range of middle grade public schools US students attend. Using a cross-sectional dataset from the eighth grade wave of the Early Childhood Longitudinal Study-Kindergarten Cohort 1998-1999, the current study examines the middle grade school social context from the perspectives of administrators and teachers in public schools with typical grade configurations (k-8 schools, middle schools, and junior high schools) and how it relates to students' perceptions of school climate. We find that administrators and teachers in k-8 schools perceive a more positive school social context, controlling for school structural and demographic characteristics. This school social context, in turn, is associated with students' perceptions of their schools' social and academic climate. Implications for educational policy and practice are discussed.

Written by an Israeli, this article looks at the nuclear proliferation risks in the Middle Eastern area. It firsts sets the Middle Eastern political scene, then discusses the Non-Proliferation Treaty as perceived in Israel. The nuclear capabilities and intentions of the Middle Eastern Countries are examined and an assessment made of the prospects for non-proliferation. The author is not optimistic as it is felt that Iraq, Iran and possibly Egypt will all want to develop a nuclear weapon capability in spite of their formal commitment to the NPT. (U.K.)

New understandings of the lithofacies paleogeography of the middle assemblage of Majiagou Fm in the Ordos Basin and its exploration significance

Directory of Open Access Journals (Sweden)

Jinhua Fu

2017-07-01

Full Text Available Accurate lithofacies-paleogeographic reconstruction is of great significance in predicting the dolomite reservoir distribution of the middle assemblage of Ordovician Majiagou Fm in the Ordos Basin. In this paper, the controlling effects of palaeotectonic background over sedimentation were first analyzed. Then the sedimentary mode of the middle assemblage was established and the lithofacies-paleogeography was reconstructed objectively for three intervals (Ma55, Ma57 and Ma59, based on the observation results of a large number of drilling cores and rock sections, together with the results of logging interpretation of rock composition and structure, single factor maps analysis and seismic data interpretation. The following findings were obtained. First, the middle assemblage of Majiagou Fm presents the uplift-depression alternation; two secondary low uplift zones extending in NS, i.e. Wushen Banner–Wuqi and Shenmu–Yulin–Yan'an, are developed in the eastern side of the central paleo-uplift, between which there is intraplatform depression, and lagoons are deposited in the Mizhi area in the east of the basin. Second, in the Ordos Basin, four NE-trending rift troughs are developed in the Proterozoic, which greatly affects the Ordovician sedimentary pattern and controls the distribution of intraplatform grain banks. Third, influenced jointly by the uplift-depression alternation and the intraplatform rift troughs of the Proterozoic, the intraplatform grain banks in the middle assemblage are mainly developed in the two low uplift zones, i.e. Shenmu–Yulin–Yan'an and Wushen Banner–Wuqi, trending NE in a similar echelon distribution. In conclusion, the two low uplift zones are the main development areas for high-quality carbonate reservoirs within the middle assemblage of Majiagou Fm in the basin.

Security concerns in the Middle East for oil supply: Problems and solutions

Sen, Samil; Babali, Tuncay

2007-01-01

Comprising 65-70% of the world's oil reserves, the Gulf States (Saudi Arabia, Iran, Iraq, Kuwait, UAE and Qatar) are key countries for the solutions to the energy supply matters of the world. Free flow of oil to the world markets from Gulf region is an indispensable part of the major security issues. The Middle East has had mainly security related problems such as Arab-Israeli wars and conflicts, Arab-Iranian war and conflicts, Arab-Arab war and conflicts, US-Gulf wars and conflicts and more recently radicalism and terrorist attacks. Energy supply security requires the enhancement of the peace and cooperation between countries instead of competition. Preventive policy approaches are more suitable to address energy supply matters. Preventive strategy might be possible with the active participation of NATO within the 'out of area' type operations to the Middle East and quite possibly indirectly to the Asia-Pacific regions. Religious and ethnic radicalism and terrorist attacks has also direct effects over oil supply security matters

Salonen, O.; Autti, T.; Raininko, R.; Ylikoski, A.; Erkinjuntti, T.

1997-01-01

Our purpose was to document the MRI appearances of the brain in healthy middle-aged to elderly subjects. T2- and proton density-weighted axial slices were obtained in 61 volunteers, 30-86 years of age. After visual inspection, signal intensities of brain structures were measured on T2-weighted images. Age-related changes became increasingly apparent after age 50. The main findings were that signal intensity of the white matter increased concomitantly with widening of the cerebrospinal fluid spaces; that basal ganglia remained stable; that high-signal foci in white matter increased in number and size after the age of 50 years; that periventricular high-signal foci were constant after the age of 65 years. Our visual impression of a decrease in signal intensity of the central grey matter with age seems to be mistaken. Pathological processes should be suspected if periventricular foci are found in middle-aged or young subjects. (orig.). With 9 figs., 1 tab

2011-01-01

Full Text Available The majority of dental carie studies over the course of historical period underline mainly the prevalence evolution, the role of carbohydrates consumption and the impact of access to dietary resources. The purpose of the present investigation was to compare population samples from two archaeological periods the Chacolithic and Middle Age taking into account the geographical and socio economical situation. The study concerned four archaelogical sites in south west France and population samples an inlander for the Chalcolithic Age, an inlander, an costal and urban for the Middle Age. The materials studied included a total of 127 maxillaries, 103 mandibles and 3316 teeth. Data recorded allowed us to display that the Chalcolithic population sample had the lowest carie percentage and the rural inlander population samples of Middle Age the highest; in all cases molars were teeth most often affected. These ones differences could be explained according to time period, carious lesions were usually less recorded in the Chalcolithic Age than the Middle because of a lesser cultivation of cereals like in les Treilles Chacolithic population sample. In the Middle Age population samples, the rural inland sample Marsan showed the highest frequency of caries and ate more cereal than the coastal Vilarnau and the poor urban St Michel population samples, the first one ate fish and Mediterranean vegetal and fruits and the second one met difficulties to food access, in both cases the consumption of carbohydrates was lesser than Marsan population sample who lived in a geographical land convice to cereals cultivation.

2014-05-01

Honduras has made steady progress in expanding post-primary school coverage in recent years, but many rural communities still do not provide a middle (lower secondary) school. As a result, Honduras has implemented a number of middle school alternative programmes designed to meet the needs of at-risk populations throughout the country. This article analyses dropout in three of the four main alternative lower secondary school programmes in Honduras over a three-year period for a cohort of roughly 5,500 students. The results show that these programmes are indeed reaching a vulnerable population in the country, but dropout rates are generally very high - upwards of 50 per cent in some cases - between Grades 7 and 9. Furthermore, even in the control school comparison samples made up of formal lower secondary schools, about 25 per cent of children leave school between Grades 7 and 9. The authors' analysis includes propensity score matching (PSM) methods that make more focused comparisons between students in alternative programmes and control samples. These results show that dropout rates in alternative programmes are not much different than in control schools, and only significant in one programme comparison, when taking into account family background characteristics like socioeconomic status (SES). Multivariate analysis within alternative programme samples finds that attrition is lower in those learning centres which have adopted key features of formal schools, such as university-educated teachers. The results highlight the tremendous variation in the alternative middle school sector in terms of programme features, school quality and student outcomes, as well as the challenges of expanding this sector to meet the growing demand for lower secondary schooling in Honduras.

Tackling cancer burden in the Middle East: Qatar as an example.

Science.gov (United States)

Brown, Robert; Kerr, Karen; Haoudi, Abdelali; Darzi, Ara

2012-11-01

Cancer prevalence is increasing in the Middle East, partly because of increased life expectancy and adoption of western lifestyle habits. Suboptimum delivery of health care also contributes to late diagnosis and poor survival of people with cancer. Public awareness of cancer risk is frequently low and misconceptions high, thereby preventing patients from seeking treatment early and constituting a substantial barrier to improvement of cancer outcomes. Screening programmes might have low uptake in Arab populations because of social and health beliefs about cancer. This review outlines the opportunities available to Middle Eastern countries and their emerging economies to learn from global experiences in cancer care, service provision, and research partnerships. The Middle East has begun to develop several health-care transformation programmes. Qatar, in particular, has published a National Health Strategy, in which cancer is one of the main commitments; this Strategy provides the focus of this review. The development of effective health-care strategies and evidence-based medicine directly linked to innovative cancer research is needed to improve cancer care. Although the full extent of the proposed solutions are not necessarily implementable in all Middle Eastern countries, wealthy states can lead derivation of population-specific approaches that could have effects throughout the region. Key challenges are outlined-namely, human capacity and training, subspecialisation of services, building on international cancer research initiatives, and the need for earlier diagnosis and awareness in the population. Countries in the Gulf Region (ie, countries bordering the Persian Gulf, including Iran, Iraq, Kuwait, Saudi Arabia, Bahrain, Qatar, UAE, and Oman) need to address these challenges to be at the forefront of integrated cancer care and research and ensure that the latest innovations and best possible care are delivered to their populations.

Ganz, Freda D; Wagner, Nurit; Toren, Orly

2015-02-01

Nurse managers are placed in a unique position within the healthcare system where they greatly impact upon the nursing work environment. Ethical dilemmas and moral distress have been reported for staff nurses but not for nurse middle managers. To describe ethical dilemmas and moral distress among nurse middle managers arising from situations of ethical conflict. The Ethical Dilemmas in Nursing-Middle Manager Questionnaire and a personal characteristics questionnaire were administered to a convenience sample of middle managers from four hospitals in Israel. Middle managers report low to moderate levels of frequency and intensity of ethical dilemmas and moral distress. Highest scores were for administrative dilemmas. Middle managers experience lower levels of ethical dilemmas and moral distress than staff nurses, which are irrespective of their personal characteristics. Interventions should be developed, studied, and then incorporated into institutional frameworks in order to improve this situation. © The Author(s) 2014.

The taphonomy of a Middle Devensian (MIS 3) vertebrate assemblage from Lynford, Norfolk, UK, and its implications for Middle Palaeolithic subsistence strategies

Science.gov (United States)

Schreve, Danielle C.

2006-07-01

The association of a rich lithic assemblage with a Middle Devensian mammalian assemblage at Lynford was initially thought indicative of a mammoth butchery locality, a rare occurrence for a European Middle Palaeolithic open site. However, taphonomic analyses suggest that the specimens have very different depositional histories and were incorporated into a palaeochannel in several stages. Most specimens are extremely fragmentary, probably the result of extensive trampling, and signs of weathering and root-damage provide further indications of exposure before burial. Carnivore damage is minimal but establishing the degree of interaction between the mammal fauna and alternative predators, such as Neanderthals, is problematic. Direct evidence of butchery is not present and the best indication of any form of mammoth exploitation lies in more circumstantial evidence such as the virtual absence of long bones from the main channel deposit and the mammoth age profiles. Instances of pathologies are also unusually common in the mammoths, implying that their greater vulnerability may have led to an accelerated demise either naturally or at the hands of a predator. The best evidence for direct faunal exploitation at the site is from green bone fractures and broken teeth that suggest marrow extraction in horse, reindeer and woolly rhinoceros. Copyright

Implementing complex innovations: factors influencing middle manager support.

Chuang, Emmeline; Jason, Kendra; Morgan, Jennifer Craft

2011-01-01

Middle manager resistance is often described as a major challenge for upper-level administrators seeking to implement complex innovations such as evidence-based protocols or new skills training. However, factors influencing middle manager support for innovation implementation are currently understudied in the U.S. health care literature. This article examined the factors that influence middle managers' support for and participation in the implementation of work-based learning, a complex innovation adopted by health care organizations to improve the jobs, educational pathways, skills, and/or credentials of their frontline workers. We conducted semistructured interviews and focus groups with 92 middle managers in 17 health care organizations. Questions focused on understanding middle managers' support for work-based learning as a complex innovation, facilitators and barriers to the implementation process, and the systems changes needed to support the implementation of this innovation. Factors that emerged as influential to middle manager support were similar to those found in broader models of innovation implementation within the health care literature. However, our findings extend previous research by developing an understanding about how middle managers perceived these constructs and by identifying specific strategies for how to influence middle manager support for the innovation implementation process. These findings were generally consistent across different types of health care organizations. Study findings suggest that middle manager support was highest when managers felt the innovation fit their workplace needs and priorities and when they had more discretion and control over how it was implemented. Leaders seeking to implement innovations should consider the interplay between middle managers' control and discretion, their narrow focus on the performance of their own departments or units, and the dedication of staff and other resources for empowering their

The present study was conducted to determine the perceptions of middle-aged women of reproductive changes. The present study was a qualitative research with a content analysis approach. The participants were 30 middle-aged women whose perceptions of reproductive changes had been collected on in-depth semi-structured interviews. The data were analyzed using the Graneheim and Lundman's inductive content analysis method. The main themes extracted from the data were a sense of "fall" and "the beginning of a new life cycle." A feeling of fall was formed from the subthemes "deterioration of youth," "the dusk of femininity," and "fade-out of the gender roles." The theme "beginning of a new life cycle" was formed from the subthemes of "acceptance," "sophistication," and "maturity." Middle-aged women had a wide range of emotions experienced from the reproductive changes ranging from a feeling of decline to that of excellence and rise.

Outdoor particulate matter (PM and associated cardiovascular diseases in the Middle East

Zeina Nasser

2015-08-01

Full Text Available Air pollution is a widespread environmental concern. Considerable epidemiological evidence indicates air pollution, particularly particulate matter (PM, as a major risk factor for cardiovascular diseases (CVD in the developed countries. The main objective of our review is to assess the levels and sources of PM across the Middle East area and to search evidence for the relationship between PM exposure and CVD. An extensive review of the published literature pertaining to the subject (2000–2013 was conducted using PubMed, Medline and Google Scholar databases. We reveal that low utilization of public transport, ageing vehicle fleet and the increasing number of personal cars in the developing countries all contribute to the traffic congestion and aggravate the pollution problem. The annual average values of PM pollutants in the Middle East region are much higher than the World Health Organization 2006 guidelines (PM2.5 = 10 μg/m3, PM10 = 20 μg/m3. We uncover evidence on the association between PM and CVD in 4 Middle East countries: Iran, Kingdom of Saudi Arabia, Qatar and the United Arab Emirates. The findings are in light of the international figures. Ambient PM pollution is considered a potential risk factor for platelet activation and atherosclerosis and has been found to be linked with an increased risk for mortality and hospital admissions due to CVD. This review highlights the importance of developing a strategy to improve air quality and reduce outdoor air pollution in the developing countries, particularly in the Middle East. Future studies should weigh the potential impact of PM on the overall burden of cardiac diseases.

THE ANALYSIS OF THE STATE AND DEVELOPMENT PROSPECTS OF THE MIDDLE CLASS IN UKRAINE

Yana Salo

2016-11-01

Full Text Available The purpose of the paper is to study and represent the current state of the middle class in Ukraine, the problems of its formation and development prospects in the future with the definition of the complementary set of internal and external factors of its formation. Methodology. The survey is based on statistical data from open official sources, which makes it possible to confirm the thesis of the critical proportion of the middle class in Ukraine. Besides, the data are obtained from electronic sources, the State Statistics Service of Ukraine. During the study, the paper uses analytical articles on the economic development of the middle class in Ukraine. The results of the survey shows that the middle class is critically low for stable functioning of Ukraine’s modern economy. One of the main problems of the middle class development is the absence of state support of small and medium-sized businesses. The government with the repressive model of the economy in relation to business-oriented monopolization was formed in Ukraine. The distribution of the «shadow» model of social and economic relations leads to the limitation of legal opportunities of employment and income. Besides, it complicates the development of small and mediumsized businesses. As a consequence, the number of entrepreneurs and small business owners are constantly increasing, but due to the absence of a favorable business climate a significant number of small businesses were forced to move into the shadow. The peculiarity of the formation of the middle class in Ukraine is that its social basis in contrast to Western Europe is not the owners, but employees. We have a unique situation, when most of the highly skilled workers (the representatives of the spheres of education, health, public administration, which should be the core of the middle class, in terms of income are on the verge or below the poverty line. The level of wages of such specialists does not even correspond to

2014-01-01

Increasing rates of inflammatory bowel disease (IBD) are now seen in populations where it was once uncommon. The pattern of IBD in children of Middle Eastern descent in Australia has never been reported. This study aimed to investigate the burden of IBD in children of Middle Eastern descent at the Sydney Children's Hospital, Randwick (SCHR). The SCHR IBD database was used to identify patients of self-reported Middle Eastern ethnicity diagnosed between 1987 and 2011. Demographic, diagnosis, and management data was collected for all Middle Eastern children and an age and gender matched non-Middle Eastern IBD control group. Twenty-four patients of Middle Eastern descent were identified. Middle Eastern Crohn's disease patients had higher disease activity at diagnosis, higher use of thiopurines, and less restricted colonic disease than controls. Although there were limitations with this dataset, we estimated a higher prevalence of IBD in Middle Eastern children and they had a different disease phenotype and behavior compared to the control group, with less disease restricted to the colon and likely a more active disease course.

Strength Training for Middle- and Long-Distance Performance: A Meta-Analysis.

Berryman, Nicolas; Mujika, Inigo; Arvisais, Denis; Roubeix, Marie; Binet, Carl; Bosquet, Laurent

2018-01-01

To assess the net effects of strength training on middle- and long-distance performance through a meta-analysis of the available literature. Three databases were searched, from which 28 of 554 potential studies met all inclusion criteria. Standardized mean differences (SMDs) were calculated and weighted by the inverse of variance to calculate an overall effect and its 95% confidence interval (CI). Subgroup analyses were conducted to determine whether the strength-training intensity, duration, and frequency and population performance level, age, sex, and sport were outcomes that might influence the magnitude of the effect. The implementation of a strength-training mesocycle in running, cycling, cross-country skiing, and swimming was associated with moderate improvements in middle- and long-distance performance (net SMD [95%CI] = 0.52 [0.33-0.70]). These results were associated with improvements in the energy cost of locomotion (0.65 [0.32-0.98]), maximal force (0.99 [0.80-1.18]), and maximal power (0.50 [0.34-0.67]). Maximal-force training led to greater improvements than other intensities. Subgroup analyses also revealed that beneficial effects on performance were consistent irrespective of the athletes' level. Taken together, these results provide a framework that supports the implementation of strength training in addition to traditional sport-specific training to improve middle- and long-distance performance, mainly through improvements in the energy cost of locomotion, maximal power, and maximal strength.

A 64-year-old woman had received radiotherapy, following surgery of a chromophobe putuitary adenoma. Six years after irradiation she began to complain of headache and dementia. Right vertebrogram demonstrated a right temporal mass lesion, stenosis and dilatation of middle cerebral artery and posterior communicating artery in the field of irradiation. CT scan showed the irregular low density area at the right temporal region, and the irregular enhancement after an intravenous injection of contrast medium was seen at the small part of affected area. From these findings, radiation necrosis at the right temporal lobe was diagnosed. As vascular changes of the main cerebral arteries due to radiation are rare, we discussed on them from ever reported literature. (author)

Antinuclear movement in Middle Tennessee

International Nuclear Information System (INIS)

Dwyer, L.E.

1977-01-01

This is a social anthropological analysis of the antinuclear movement in Middle Tennessee. This social movement was determined to halt the construction of proposed nuclear power plants in Tennessee, especially one the Tennessee Valley Authority (TVA) intended to build in Middle Tennessee. The data for the study were gathered by participant-observation interviewing, and the examination of documents from February 1973 through March 1975. The treatment of the data is based on transactional analysis and portions of the network model. This social movement was composed of a series of informally organized cells connected by a loose network of people who visited and talked with one another. Individual cells tended to be organized on a geographical basis, as was communication. Activity-initiators, however, often contacted antinuclear personnel in other Middle Tennessee cells. Movement activity for many of the antinuclear activists was short-lived. The strategic maneuvers of the movement utilized all the structurally and legally possible alternatives and the nuclear opponents hoped that the public would pressure public officials to oppose nuclear plants. Although the antinuclear activists worked very hard, they did not succeed in halting the planned construction of the Middle Tennessee nuclear plant. Indeed, they had not succeeded in the summer of 1977

The aim of this article is twofold: (a) to present the principles and the indications of surgical treatment of middle ear pathologies; and (b) to review the imaging findings after middle ear surgery, including the normal postoperative aspects and imaging findings in patients presenting with unsatisfactory surgical results or with suspicion of postoperative complications. This review is intentionally restricted to the most common diseases involving the middle ear: chronic otitis media and otosclerosis. In these specific fields of interest, CT and MR imaging play a very important role in the postoperative follow-up and in the work-up of surgical failures and complications. (orig.)

Middle cranial fossa approach for the repair of spontaneous cerebrospinal fluid leaks to the middle ear.

Science.gov (United States)

Altuna, Xabier; Navarro, Juan José; García, Leire; Ugarte, Ane; Thomas, Izaskun

Spontaneous cerebrospinal fluid (CSF) leaks to the middle ear due to tegmen tympani defects can result in hearing loss or hypoacusis and predispose to meningitis as well as other neurological complications. Surgical repair of the defect can be performed through a middle cranial fossa (MCF) approach or a transmastoid approach. We conducted a retrospective study of the patients in our Department due to a spontaneous CSF leak to the middle ear treated using a MCF approach during a 6-year period (2009-2014). Thirteen patients with spontaneous CSF leak to the middle ear were treated with this approach. The primary and first symptom in all of them was conductive hearing loss. In all cases, the defect or defects were closed in a multilayer manner using muscle, temporalis fascia and cortical bone. Minimum follow-up in this series was 14 months, with successful closure in all but one patient (who required reintervention). We found no intra- or postoperative complications due to the craniotomy, and the audiometry improved and normalised in all cases except for the failed case. The MCF approach with a multilayer closure of the defect is an effective technique for repairing spontaneous CSF leaks to the middle ear and for restoring hearing in these patients.

1994-04-01

Full Text Available A study on the variability of temperature in the tropical middle atmosphere over Thumba (8 32' N, 76 52' E, located at the southern part of India, has been carried out based on rocket observations for a period of 20 years, extending from 1970 to 1990. The rocketsonde-derived mean temperatures over Thumba are corrected prior to 1978 and then compared with the middle atmospheric reference model developed from satellite observations and Solar Mesosphere Explorer (SME satellite data. Temperature variability at every 1 km interval in the 25-75 km region was analysed. The tropical stratosphere is found to be highly stable, whereas considerable variability is noted in the middle mesosphere. The effect of seasonal cycle is least in the lower stratosphere. Annual and semi-annual oscillations in temperature are the primary oscillations in the tropical middle atmosphere. Annual temperature oscillations are dominant in the mesosphere and semi-annual oscillations are strong in the stratosphere. The stratopause region is noted to be the part of the middle atmosphere least sensitive to the changes in solar activity and long-term variability.

2010-02-01

The purpose of this study was to analyze nursing-related content in middle, and high school textbooks under the National Common Basic Curriculum in Korea. Nursing-related content from 43 middle school textbooks and 13 high school textbooks was analyzed. There were 28 items of nursing-related content in the selected textbooks. Among them, 13 items were in the 'nursing activity' area, 6 items were in the 'nurse as an occupation' area, 2 items were in the 'major and career choice' area, 6 items were 'just one word' and 1 item in 'others'. The main nursing related content which portrayed in the middle and high school textbooks were caring for patients (7 items accounting for 46.5%), nurses working in hospitals (6 items accounting for 21.4%). In terms of gender perspective, female nurses (15 items accounting for 53.6%) were most prevalent.

Middle atmosphere electrical energy coupling

Science.gov (United States)

Hale, L. C.

1989-01-01

The middle atmosphere (MA) has long been known as an absorber of radio waves, and as a region of nonlinear interactions among waves. The region of highest transverse conductivity near the top of the MA provides a common return for global thunderstorm, auroral Birkeland, and ionospheric dynamo currents, with possibilities for coupling among them. Their associated fields and other transverse fields map to lower altitudes depending on scale size. Evidence now exists for motion-driven aerosol generators, and for charge trapped at the base of magnetic field lines, both capable of producing large MA electric fields. Ionospheric Maxwell currents (curl H) parallel to the magnetic field appear to map to lower altitudes, with rapidly time-varying components appearing as displacement currents in the stratosphere. Lightning couples a (primarily ELF and ULF) current transient to the ionosphere and magnetosphere whose wave shape is largely dependent on the MA conductivity profile. Electrical energy is of direct significance mainly in the upper MA, but electrodynamic transport of minor constituents such as smoke particles or CN may be important at other altitudes.

The middle manager role in energy company environmental efforts

Science.gov (United States)

Fischhoff, Maya E.

2005-12-01

This research examines the internal organizational processes determining corporate environmental action. Corporations have a tremendous environmental impact, yet relatively little is known about how employees within them view and work on these issues. The research focused on middle managers, a level of the company whose value is often questioned. Interviews were conducted with 70 middle managers at two energy companies (comprising utilities and unregulated businesses). Interviews examined the shape and significance of middle manager involvement in environmental issues, looking specifically at what issues middle managers deal with, what goals they pursue, and what approaches they use. The research finds middle managers' roles with respect to environmental issues to be far-reaching and complex. Much of their effort is focused on meeting regulatory requirements ("complying"). They are committed to compliance, in part for ethical reasons, but often find regulations frustrating and costly. Compliance is more challenging than commonly thought; it demands time, knowledge, and substantial creativity. In pursuing it, interviewees work with employees throughout the organization. This research shows middle managers interacting with those hierarchically above and below them in ways that greatly modify earlier portrayals of middle managers. Earlier portrayals often emphasized struggles for power within the organization. Here, middle managers work in ways best characterized as collaborative and supportive. Middle managers also have extensive involvement laterally within the company and with groups outside the company. These links have received modest attention in literature, yet are found to be terribly important. Middle managers' lateral efforts inside the company, often on teams, allow diverse expertise (e.g., from people in different functions) to be applied to environmental issues.

To examine the frequency of toothbrushing or cleaning among middle school students from 44 low- and middle-income countries. Secondary analysis of nationally representative data from 146,462 middle school students who participated in the Global School-based Student Health Survey (GSHS) between 2003 and 2010. In 39 of the 44 countries, more than 80% of students reported brushing or cleaning their teeth at least once each day. In 23 countries, more than 5% of participants reported brushing their teeth less than once a day or never. In 37 countries, boys reported a significantly lower frequency of toothbrushing or cleaning than did girls. Countries where miswak (chewing stick) use is common reported lower toothbrushing or cleaning frequency, perhaps because the questionnaire item did not clarify that this counts as a form of tooth cleaning. School-based dental health education programmes that target early adolescents may help students to develop habits that improve their immediate and long-term health. © 2014 FDI World Dental Federation.

Middle East natural gas - getting it to markets

International Nuclear Information System (INIS)

Skinner, R.

1996-01-01

Middle East gas reserves, production, and consumption were presented graphically, along with the demand for 'piped' or liquefied natural gas in the Middle East itself, in Asia and in Europe. The European gas market outlook was examined, taking into account economic growth, EEC restructuring, crude oil prices and their effects on net-backs, deregulation and competitive grid-based energy, upstream and midstream investments under conditions of price uncertainty, and environmental and social influences. Middle East pipeline proposals (17 projects) for a total of 34,943 kilometres of pipeline, were reviewed. The general conclusion was that (1) the Middle East has lots of gas, (2) both Asia and Europe will be substantial markets for Middle East LNG despite the 'tyranny of distance', and (3) pipelines to these markets will be built in the longer-term. tabs., figs

2015-01-01

Air pollution is a widespread environmental concern. Considerable epidemiological evidence indicates air pollution, particularly particulate matter (PM), as a major risk factor for cardiovascular diseases (CVD) in the developed countries. The main objective of our review is to assess the levels and sources of PM across the Middle East area and to search evidence for the relationship between PM exposure and CVD. An extensive review of the published literature pertaining to the subject (2000-2013) was conducted using PubMed, Medline and Google Scholar databases. We reveal that low utilization of public transport, ageing vehicle fleet and the increasing number of personal cars in the developing countries all contribute to the traffic congestion and aggravate the pollution problem. The annual average values of PM pollutants in the Middle East region are much higher than the World Health Organization 2006 guidelines (PM2.5 = 10 μg/m(3), PM10 = 20 μg/m(3)). We uncover evidence on the association between PM and CVD in 4 Middle East countries: Iran, Kingdom of Saudi Arabia, Qatar and the United Arab Emirates. The findings are in light of the international figures. Ambient PM pollution is considered a potential risk factor for platelet activation and atherosclerosis and has been found to be linked with an increased risk for mortality and hospital admissions due to CVD. This review highlights the importance of developing a strategy to improve air quality and reduce outdoor air pollution in the developing countries, particularly in the Middle East. Future studies should weigh the potential impact of PM on the overall burden of cardiac diseases. This work is available in Open Access model and licensed under a CC BY-NC 3.0 PL license.

Contractor companies must have the competitive advantage to compete in maintaining the survival of the company. Problems arise because quite a lot of advantages can be used and these advantages must be used appropriately to produce competitiveness for the company to continue to compete and to win the competition. This study aims to determine the main factors affecting the competitiveness of medium-class contractors in Banda Aceh. Data collection was obtained through questionnaires distributed to 31 middle-class contractors in Banda Aceh. Data processing and analysis is done by using descriptive analysis. Based on the result of descriptive analysis, it can be concluded that the most important competitiveness factor with a mean score value 4.52 is the relationship, and the factor that has the highest mean score value is the relationship with the government of 4.97, while the result of the ranking analysis is obtained 25 factor that is critical to the competitiveness of medium-class contractors in Banda Aceh.

Basaltic material in the main belt: a tale of two (or more) parent bodies?

The majority of basaltic objects in the main belt are dynamically connected to Vesta, the largest differentiated asteroid known. Others, due to their current orbital parameters, cannot be easily dynamically linked to Vesta. This is particularly true for all the basaltic asteroids located beyond 2.5 au, where lies the 3:1 mean motion resonance with Jupiter. In order to investigate the presence of other V-type asteroids in the middle and outer main belt (MOVs) we started an observational campaign to spectroscopically characterize in the visible range MOV candidates. We observed 18 basaltic candidates from TNG and ESO - NTT between 2015 and 2016. We derived spectral parameters using the same approach adopted in our recent statistical analysis and we compared our data with orbital parameters to look for possible clusters of MOVs in the main belt, symptomatic for a new basaltic family. Our analysis seemed to point out that MOVs show different spectral parameters respect to other basaltic bodies in the main belt, which could account for a diverse mineralogy than Vesta; moreover, some of them belong to the Eos family, suggesting the possibility of another basaltic progenitor. This could have strong repercussions on the temperature gradient present in the early Solar System, and on our current understanding of differentiation processes.

Decline of seminal parameters in middle-aged males is associated with lower urinary tract symptoms, prostate enlargement and bladder outlet obstruction

Directory of Open Access Journals (Sweden)

Kristo Ausmees

2013-09-01

Full Text Available Purpose We aimed to compare the associations between semen quality, associated reproductive indicators and the main prostate-related parameters in middle-aged men. Materials and Methods: This is a prospective study on 422 middle-aged men who underwent the screening for prostate health. Their reproductive function, semen quality and prostate-related pathologies were investigated. Results Significant associations between semen quality and prostate-related parameters could be seen. Total sperm count and sperm density decreased along with the increase of the I-PSS score and total prostate volume. Also, the related lower urinary tract characteristics showed a negative correlation with main semen parameters for all investigated subjects. No significant differences in age, testicular size, and hormonal parameters were found between the subjects with or without lower urinary tract symptoms and prostate enlargement. Conclusions Our study suggests that altered seminal parameters in middle-aged men are associated with LUTS, prostate enlargement and/or bladder outlet obstruction. Although the assessments of prostate and lower urinary tract symptoms may not replace the semen parameters evaluating the male reproductive status, there is a need for further and more detailed investigations about the pathways behind these associations as well as possible related conditions.

Backett-Milburn, Kathryn C; Wills, Wendy J; Roberts, Mei-Li; Lawton, Julia

2010-10-01

This paper reports findings from a qualitative study of views and understandings of dietary practices in middle class families. Thirty five parents/main food providers of boys and girls aged 13/14 years, living in Eastern Scotland, were interviewed about their and their teenagers' everyday lives, food, health and family practices. One of our aims was to understand more about the social and cultural conditions which might be promoting more positive dietary health and physical well-being amongst middle class families. Most parents' accounts appeared rooted in a taken-for-grantedness that family members enjoyed good health, lived in relatively secure and unthreatening environments regarding health and resources, and were able to lead active lives, which they valued. Although controlling teenagers' eating practices was presented as an ongoing challenge, active supervision and surveillance of their diets was described, as was guiding tastes in 'the right direction'. Parents described attempts to achieve family eating practices such as commensality, cooking from scratch, and encouraging a varied and nutritional 'adult' diet and cosmopolitan tastes, though work and activities could compromise these. These middle class families might be characterized as having future oriented 'hierarchies of luxury and choice', in which controlling and moulding teenagers' food practices and tastes was assigned a high priority.

Unappreciated diversification of stem archosaurs during the Middle Triassic predated the dominance of dinosaurs.

Foth, Christian; Ezcurra, Martín D; Sookias, Roland B; Brusatte, Stephen L; Butler, Richard J

2016-09-15

Archosauromorpha originated in the middle-late Permian, radiated during the Triassic, and gave rise to the crown group Archosauria, a highly successful clade of reptiles in terrestrial ecosystems over the last 250 million years. However, scientific attention has mainly focused on the diversification of archosaurs, while their stem lineage (i.e. non-archosaurian archosauromorphs) has often been overlooked in discussions of the evolutionary success of Archosauria. Here, we analyse the cranial disparity of late Permian to Early Jurassic archosauromorphs and make comparisons between non-archosaurian archosauromorphs and archosaurs (including Pseudosuchia and Ornithodira) on the basis of two-dimensional geometric morphometrics. Our analysis recovers previously unappreciated high morphological disparity for non-archosaurian archosauromorphs, especially during the Middle Triassic, which abruptly declined during the early Late Triassic (Carnian). By contrast, cranial disparity of archosaurs increased from the Middle Triassic into the Late Triassic, declined during the end-Triassic extinction, but re-expanded towards the end of the Early Jurassic. Our study indicates that non-archosaurian archosauromorphs were highly diverse components of terrestrial ecosystems prior to the major radiation of archosaurs, including dinosaurs, while disparity patterns of the Ladinian and Carnian indicate a gradual faunal replacement of stem archosaurs by the crown group, including a short interval of partial overlap in morphospace during the Ladinian.

The Middle to Upper Paleolithic transition is one of the crucial periods of change in the prehistory of Europe due to the full emergence, continent-wide, of modern human technologies, detrimental of Neanderthal survival. Knowledge about the transition is vast, however, the evidence for cultural and technological developments in the Carpathian - Lower Danube area is still rather sparse. Here we discuss latest results arising from an archaeological-chronological investigation of a Middle Paleolithic context within the Varghis karst, eastern Transylvania, Romania. Combining our results with these of previous excavations, we can distinguish several stages of habitation in the area comprising a rock shelter connected to a newly discovered filled-in cave entrance. Reanalysis of the deeper stratigraphy previously unexcavated shows that at least two main habitation levels have been preserved. In both levels, the bone assemblages (Bos/Bison, Capra, Canis lupus, Ursus spaeleus) directly associated with lithics point to human-accumulation of material. In order to augment the typological cultural considerations, we applied direct radiocarbon dating on bones from within the occupation layers and on scattered charcoal, for the latter following a two-step combustion protocol (1). Radiocarbon dating on bones suggests the lowermost occupation layer is >43.4 radiocarbon kyr BP old, whereas the preliminary infrared stimulated luminescence (IRSL) ages on the lowermost productive layer and above it indicate surprisingly old ages of ca. 120 kyr and respectively, ca. 70 kyr. Multiple-protocol dating of charcoal found within the two habitation layers produced ages >38 radiocarbon kyr BP, suggesting that the lowermost habitation layer unequivocally pertains to the Middle Paleolithic industries. For the upper productive layer, radiocarbon dating of charcoal found 20 cm above it produced a surprisingly young age of 17.4 radiocarbon kyr BP. However, as the carbon content of this sample was

Security concerns in the Middle East for oil supply: Problems and solutions

Comprising 65-70% of the world's oil reserves, the Gulf States (Saudi Arabia, Iran, Iraq, Kuwait, UAE and Qatar) are key countries for the solutions to the energy supply matters of the world. Free flow of oil to the world markets from Gulf region is an indispensable part of the major security issues. The Middle East has had mainly security related problems such as Arab-Israeli wars and conflicts, Arab-Iranian war and conflicts, Arab-Arab war and conflicts, US-Gulf wars and conflicts and more recently radicalism and terrorist attacks. Energy supply security requires the enhancement of the peace and cooperation between countries instead of competition. Preventive policy approaches are more suitable to address energy supply matters. Preventive strategy might be possible with the active participation of NATO within the 'out of area' type operations to the Middle East and quite possibly indirectly to the Asia-Pacific regions.

Full Text Available Although it has been argued that the structure of executive function (EF may change developmentally, there is little empirical research to examine this view in middle childhood and adolescence. The main objective of this study was to examine developmental changes in the component structure of EF in a large sample (N = 457 of 7-15 year olds. Participants completed batteries of tasks that measured three components of EF: updating working memory (UWM, inhibition, and shifting. Confirmatory factor analysis (CFA was used to test five alternative models in 7-9 year olds, 10-12 year olds, and 13-15 year olds. The results of CFA showed that a single-factor EF model best explained EF performance in 7-9-year-old and 10-12-year-old groups, namely unitary EF, though this single factor explained different amounts of variance at these two ages. In contrast, a three-factor model that included UWM, inhibition, and shifting best accounted for the data from 13-15 year olds, namely diverse EF. In sum, during middle childhood, putative measures of UWM, inhibition, and shifting may rely on similar underlying cognitive processes. Importantly, our findings suggest that developmental dissociations in these three EF components do not emerge until children transition into adolescence. These findings provided empirical evidence for the development of EF structure which progressed from unity to diversity during middle childhood and adolescence.

Full Text Available Floodplain lakes and peatlands in the middle Mahakam lowland area are considered as ecologically important wetland in East Kalimantan, Indonesia. However, due to a lack of data, the hydrological functioning of the region is still poorly understood. Among remote sensing techniques that can increase data availability, radar is well-suitable for the identification, mapping, and measurement of tropical wetlands, for its cloud unimpeded sensing and night and day operation. Here we aim to extract flood extent and flood occurrence information from a series of radar images of the middle Mahakam lowland area. We explore the use of Phased Array L-band Synthetic Aperture Radar (PALSAR imagery for observing flood inundation dynamics by incorporating field water level measurements. Water level measurements were carried out along the river, in lakes and in peatlands, using pressure transducers. For validation of the open water flood occurrence map, bathymetry measurements were carried out in the main lakes. A series of PALSAR images covering the middle and lower Mahakam area in the years 2007 through 2010 were collected. A fully inundated region can be easily recognized on radar images from a dark signature. Open water flood occurrence was mapped using a threshold value taken from radar backscatter of the permanently inundated river and lakes areas. Radar backscatter intensity analysis of the vegetated floodplain area revealed consistently high backscatter values, indicating flood inundation under forest canopy. We used those values as the threshold for flood occurrence mapping in the vegetated area.

Market penetration of HMOs affect physician practice styles for non-HMO patients. To study the impact of a restrictive Medicaid drug formulary on prescribing patterns for other patients, ie, so-called spillover effects. A before-and-after, 3-state comparison study. On January 1, 2001, Maine's Medicaid program implemented a restrictive drug formulary for the proton pump inhibitor class, with pantoprazole as the only preferred drug. The Medicaid and non-Medicaid market shares of pantoprazole in Maine (vs New Hampshire and Vermont and among Maine physicians with different Medicaid share of practice. After 3 months, the market share of pantoprazole in Maine (vs 2 control states) increased 79% among Medicaid prescriptions (vs 1%-2%), 10% among cash prescriptions (vs 3%), and 7% among other third-party payer prescriptions (vs 1%). The market shares increased more among Maine physicians with a higher Medicaid share of practice (high vs middle vs low [market]: 16% vs 8% vs 5% [cash]; 11% vs 5% vs 4% [other third-party payers]). Linear regression results indicate that practicing medicine in Maine leads to a 72% increase in pantoprazole share among Medicaid prescriptions (P markets, with somewhat stronger effects in the cash market.

The role of the Atlantic Meridional Overturning Circulation (AMOC) as a key player for abrupt climatic changes (e.g. Heinrich Stadials) during the Pleistocene is relatively well constrained. However, the timing of the onset of a „modern" North Atlantic Deepwater (NADW) formation are still debated: Recent estimates range from the middle Miocene to the Early Eocene [Davies et al., 2001, Stoker et al., 2005, Hohbein et al., 2012] and are mainly based on the seismic interpretation contourite drifts. Another understudied aspect of the AMOC is its behavior during climatic variations on orbital time scales and under different climatic boundary conditions (icehouse vs hothouse). IODP Expedition 342 drilled carbonate-rich sequences from sediment drifts offshore Newfoundland that cover the middle Eocene with high sedimentation rates ( 3 cm/ kyr).

Leisure may serve as a coping resource following negative life events that facilitate positive changes. Previous studies on leisure have mainly focused on stress-related growth among individuals living in Western cultures. This study aimed to capture the role of leisure involvement as a facilitator of stress-related growth among middle-aged Korean women with depression. Three main themes were identified as an outcome of participation in leisure activities: (a) strengthening meaningful relationships, (b) improving positive emotions, and (c) facilitating personal strength. By participating in leisure activities, individuals with depression may develop the ability to cope with stress and experience positive changes.

Abstract Studies examining student motivation levels suggest that this is a significant factor in students’ engagement in physical education and may be positively affected when teachers employ alternative pedagogical models such as game-centered approaches (GCAs). The aim of this study was to investigate changes in self-determined motivation of students as they participated in a GCA-basketball unit taught using the Tactical Games Model (TGM). Participants were 173 students (84 girls), 79 middle school (45 girls) and 94 (39 girls) elementary school students from four seventh and five fourth/fifth grade co-educational classes. Two teachers taught 32 (middle) and 33 (elementary) level one TGM basketball lessons. Need satisfaction and self-determined motivation data were collected using a previously validated instrument, while lesson context and teacher behavior data were recorded using systematic observation instruments. Repeated measures MANOVAs were employed to examine pre-posttest differences. Results revealed a significant main effect for time in need satisfaction for both middle (relatedness increased) and elementary school students (autonomy decreased) and a significant main effect in self-determined motivation for middle school students only (introjected regulation, external regulation, and amotivation all increased). Approximately 48%/42% (middle/elementary) of lesson time was game play, 22%/22% skill practice, 17%/17% management, and 13%/19% knowledge. The primary teacher behaviors used were instruction, management, specific observation, corrective feedback and modelling. Results indicate that it is important for future research to pay greater attention to the contextual factors associated with the application of the TGM, such as the students’ previous exposure to TGM lessons, and the teachers’ training and experience in utilizing the TGM. Indeed, results of the present study demonstrate that a longer-term commitment to the TGM is necessary to reduce

Meddling with middle modalities: a decomposition approach to mental health inequalities between intersectional gender and economic middle groups in northern Sweden

Directory of Open Access Journals (Sweden)

Per E. Gustafsson

2016-11-01

Full Text Available Background: Intersectionality has received increased interest within population health research in recent years, as a concept and framework to understand entangled dimensions of health inequalities, such as gender and socioeconomic inequalities in health. However, little attention has been paid to the intersectional middle groups, referring to those occupying positions of mixed advantage and disadvantage. Objective: This article aimed to 1 examine mental health inequalities between intersectional groups reflecting structural positions of gender and economic affluence and 2 decompose any observed health inequalities, among middle groups, into contributions from experiences and conditions representing processes of privilege and oppression. Design: Participants (N=25,585 came from the cross-sectional ‘Health on Equal Terms’ survey covering 16- to 84-year-olds in the four northernmost counties of Sweden. Six intersectional positions were constructed from gender (woman vs. men and tertiles (low vs. medium vs. high of disposable income. Mental health was measured through the General Health Questionnaire-12. Explanatory variables covered areas of material conditions, job relations, violence, domestic burden, and healthcare contacts. Analysis of variance (Aim 1 and Blinder-Oaxaca decomposition analysis (Aim 2 were used. Results: Significant mental health inequalities were found between dominant (high-income women and middle-income men and subordinate (middle-income women and low-income men middle groups. The health inequalities between adjacent middle groups were mostly explained by violence (mid-income women vs. men comparison; material conditions (mid- vs. low-income men comparison; and material needs, job relations, and unmet medical needs (high- vs. mid-income women comparison. Conclusions: The study suggests complex processes whereby dominant middle groups in the intersectional space of economic affluence and gender can leverage strategic

BACKGROUND: Studies have indicated an increasing proportion of heavy drinking among middle-aged and older Danes. Trends in consumption are often extremely sensitive to influence from various components of the time trends but only few have explored the age, period and cohort-related influences...... that the proportion of heavy drinking women increases in younger birth cohorts. This trend is not observed for men as their drinking pattern mainly increase slightly by calendar year. CONCLUSIONS: Our Danish observations for older aged individuals correspond to the social and cultural changes in the 1960s and 1970s...

Unraveling the Quaternary river incision in the Moselle valley (Rhenish Massif, Germany): new insights from cosmogenic nuclide dating (10Be/26Al) of the Main Terrace complex

Throughout the whole river network of the Rhenish Massif, the terrace complex of the so-called Main Terrace forms the morphological transition between a wide upper palaeovalley (plateau valley) and a deeply incised lower valley. The youngest level of this Main Terrace complex (YMT), directly located at the edge of the incised valley, represents a dominant geomorphic feature in the terrace flight; it is often used as a reference level to identify the start of the main middle Pleistocene incision episode (Demoulin & Hallot, 2009). The latter probably reflects the major tectonic pulse that affected the whole Massif and was related to an acceleration of the uplift rates (Demoulin & Hallot, 2009). The Main terraces are particularly well preserved in the lower Moselle valley and are characterized by a constant absolute elevation of their base along a 150 km-long reach. Despite that various hypotheses have been proposed to explain this horizontality (updoming, faulting...), all studies assumed an age of ca. 800 ka for the YMT, mainly based on the questionable extrapolation of palaeomagnetic data obtained in the Rhine valley. Therefore, a reliable chronological framework is still required to unravel the spatio-temporal characteristics of the Pleistocene evolution of the Moselle valley. In this study, we apply cosmogenic nuclide dating (10Be/26Al) to fluvial sediments pertaining to the Main Terrace complex or to the upper Middle Terraces. Several sites along the lower Moselle were sampled following two distinct sampling strategies: (i) depth profiles where the original terrace (palaeo-)surface is well preserved and did not experience much postdepositional burial (e.g., loess cover); and (ii) the isochron technique where the sediment thickness exceeds 3 m. Cosmogenic nuclide ages recently obtained for three rivers in the Meuse catchment in the western Rhenish Massif demonstrated that the Main Terraces were younger than expected and their abandonment was diachronic along the

Diabetes is a major health care burden in the Middle East region. Social networking tools can contribute to the management of diabetes with improved educational and care outcomes using these popular tools in the region. The objective of this review was to evaluate the impact of social networking interventions on the improvement of diabetes management and health outcomes in patients with diabetes in the Middle East. Peer-reviewed articles from PubMed (1990-2017) and Google Scholar (1990-2017) were identified using various combinations of predefined terms and search criteria. The main inclusion criterion consisted of the use of social networking apps on mobile phones as the primary intervention. Outcomes were grouped according to study design, type of diabetes, category of technological intervention, location, and sample size. This review included 5 articles evaluating the use of social media tools in the management of diabetes in the Middle East. In most studies, the acceptance rate for the use of social networking to optimize the management of diabetes was relatively high. Diabetes-specific management tools such as the Saudi Arabia Networking for Aiding Diabetes and Diabetes Intelligent Management System for Iraq systems helped collect patient information and lower hemoglobin A 1c (HbA 1c ) levels, respectively. The reviewed studies demonstrated the potential of social networking tools being adopted in regions in the Middle East to improve the management of diabetes. Future studies consisting of larger sample sizes spanning multiple regions would provide further insight into the use of social media for improving patient outcomes. ©Turki Alanzi.

Towards a robust and consistent middle Eocene astronomical timescale

Until now, the middle Eocene has remained a poorly constrained interval of efforts to produce an astrochronological timescale for the entire Cenozoic. This has given rise to a so-called "Eocene astronomical timescale gap" (Vandenberghe et al., 2012). A high-resolution astrochronological calibration for this interval has proven to be difficult to realize, mainly because carbonate-rich deep-marine sequences of this age are scarce. In this paper, we present records from middle Eocene carbonate-rich sequences from the North Atlantic Southeast Newfoundland Ridge (IODP Exp. 342, Sites U1408 and U1410), of which the cyclical sedimentary patterns allow for an orbital calibration of the geologic timescale between ∼38 and ∼48 Ma. These carbonate-rich cyclic sediments at Sites U1408 and U1410 were deposited as drift deposits and exhibit prominent lithological alternations (couplets) between greenish nannofossil-rich clay and white nannofossil ooze. The principal lithological couplet is driven by the obliquity of Earth's axial tilt, and the intensity of their expression is modulated by a cyclicity of about 173 kyr. This cyclicity corresponds to the interference of secular frequencies s3 and s6 (related to the precession of nodes of the Earth and Saturn, respectively). This 173-kyr obliquity amplitude modulation cycle is exceptionally well recorded in the XRF (X-ray fluorescence)-derived Ca/Fe ratio. In this work, we first demonstrate the stability of the (s3-s6) cycles using the latest astronomical solutions. Results show that this orbital component is stable back to at least 50 Ma, and can thus serve as a powerful geochronometer in the mid-Eocene portion of the Cenozoic timescale. We then exploit this potential by calibrating the geochronology of the recovered middle Eocene timescale between magnetic polarity Chrons C18n.1n and C21n. Comparison with previous timescales shows similarities, but also notable differences in durations of certain magnetic polarity chrons. We

The need to consider the Middle East as a group of distinct countries and not as one single market and to tailor the services offered by companies is stressed. The cultures, political and social conditions, forms of the oil and gas industry in the countries making up the Middle East and their technology requirements are different and vary widely. The approach taken by Shell Global Solutions to these differences is described and illustrated with Shell's experiences in Oman and Saudi Arabia. Shell has found that Omanis are keen to work in their oil and gas industry, and to protect their country's natural environment. Saudi also have intense pride in their oil industry and here Shell supports refinery operators reduce costs while maintaining strict quality control. Shell has been selected to help Saudi Arabia develop its natural gas reserves; as part of the Core Venture 3 project, Shell will build a power desalination plant

Middle East gas utilization and export potential

International Nuclear Information System (INIS)

Cornet-Gandolphe, S.

1995-01-01

There is huge gas supply potential in the Middle East, which possesses over one third of the world's natural gas reserves. However, marketed production represents only 6% of the world total, demonstrating that gas resources in the Middle East are under utilized. The value of these resources will be realized only if the gas finds a commercial outlet that guarantees proper return on investments for gas producers and the best possible use of this nonrenewable resource for governments. Apart from the chemical sector, which has provided a good outlet for natural gas, the development of natural gas resources in the region has been very limited historically, inhibited by many factors linked to the resource itself and to the characteristics of the region. However, natural gas in the Middle East is now at a crossroads, facing both major challenges and significant opportunities. The region, which currently plays only a marginal role on the world gas market, has the potential to become a leading world supplier, provided a number of political and economic conditions are fulfilled. This paper discusses some of the challenges that Middle Eastern countries face in trying to develop their natural gas resources. It reviews development potential for Middle Eastern gas reserves, whether for local use and/or exports, and it highlights future opportunities. (Author)

Tarsal morphology of the pleuraspidotheriid mammal Hilalia from the middle Eocene of Turkey

Directory of Open Access Journals (Sweden)

Gregoire Metais

2017-03-01

Full Text Available Pleuraspidotheriids are a group of primitive ungulate mammals that, until recently, were thought to be restricted to the late Paleocene of Western Europe. It has been hypothesized that this family actually survived in Central Anatolia until at least the middle Eocene. However, these anachronistically young Anatolian “survivors”, including the genus Hilalia, were previously documented mainly by dental remains. Here, we describe the previously unknown astragalus of Hilalia saribeya, which confirms the pleuraspidotheriid affinities of the genus, and supports phylogenetic reconstructions that place Hilalia as the sister group of Pleuraspidotherium. The morphology of the astragalus suggests sub-cursorial plantigrade locomotion for H. saribeya, although its tarsal morphology remains generalized enough that scansorial capabilities cannot be ruled out. The evolution of Hilalia is addressed in the context of the apparent geographic isolation of Central Anatolia during the Eocene. The endemic character of the mammalian fauna of Central Anatolia during the middle Eocene emphasizes how the complex paleogeography of the northern margin of Neotethys impacted local biotas in a region situated at the crossroads of very distinctive biogeographic zones.

Otitis media (OM), or middle ear inflammation, is the most common paediatric disease and leads to significant morbidity. Although understanding of underlying disease mechanisms is hampered by complex pathophysiology it is clear that epithelial abnormalities underpin the disease. There is currently a lack of a well-characterised in vitro model of the middle ear (ME) epithelium that replicates the complex cellular composition of the middle ear. Here, we report the development of a novel in vitro model of mouse middle ear epithelial cells (mMECs) at an air-liquid interface (ALI) that recapitulates the characteristics of the native murine ME epithelium. We demonstrate that mMECs undergo differentiation into the varied cell populations seen within the native middle ear. Proteomic analysis confirmed that the cultures secrete a multitude of innate defence proteins from their apical surface. We showed that the mMECs supported the growth of the otopathogen, nontypeable Haemophilus influenzae (NTHi), suggesting that the model can be successfully utilised to study host-pathogen interactions in the middle ear. Overall, our mMEC culture system can help to better understand the cell biology of the middle ear and improve our understanding of the pathophysiology of OM. The model also has the potential to serve as a platform for validation of treatments designed to reverse aspects of epithelial remodelling that underpin OM development. © 2016.

The objective of the study was to assess nutritional and health status as well as nutritional knowledge in urban middle-aged Malaysian women. The impact of menopause on diet and health indices was also studied. The study included 360 disease free women, non users of HRT,aged > or =45 years with an intact uterus recruited from November 1999 to October 2001. Personal characteristics, anthropometric measurements and blood sample were acquired followed by clinical examination. Nutrient intake and nutritional knowledge was determined by a quantitative FFQ and KAP. The findings showed that urban middle-aged women, aged 51.65+/-5.40 years had energy intakes (EI) 11% below RDA, consisting of 53% carbohydrates, 15% protein and a 32% fat which declined with age. The sample which comprised of 42.5% postmenopausal women had a satisfactory diet and healthy lifestyle practices. Premenopausal women consumed more dietary fat (6%) with other aspects of diet comparable to the postmenopausal women. Iron intake was deficient in premenopausal women, amounting to 56% RDA contributing to a 26% prevalence of anaemia. Overall, calcium intake reached 440 mg daily but dairy products were not the main source. The postmenopaused had a more artherogenic lipid profile with significantly higher total cholesterol (TC) and LDL-C, but more premenopausal women were overweight/obese (49% versus 35%). EI was the strongest predictor for BMI and waist circumference (WC), with WC itself an independent predictor of fasting blood sugar and TC with BMI strongly affecting glucose tolerance. High nutritional knowledge was seen in 39% whereas 20% had poor knowledge. Newspapers and magazines, followed by the subject's social circle, were the main sources of nutritional information. Nutritional knowledge was positively associated with education, household income, vitamin/ mineral supplementation and regular physical activity but inversely related to TC. In conclusion, middle-aged urban women had an adequate diet

The aim of this study was to examine the barriers to following complementary feeding guidelines among Middle Eastern mothers and the cultural considerations of practitioners from an emic perspective. This is a two-phase focused ethnographic assessment of infant feeding among 22 Middle Eastern mothers in Western Canada who had healthy infants aged foods was whether or not foods were Halal, while food allergens were not causes for concern. Vitamin D supplements were not fed to 18/22 of infants, and mashed dates (Halawi), rice pudding (Muhallabia/Ferni) and sugared water/tea were the first complementary foods commonly consumed. Through constant comparison of qualitative data, three layers of influence emerged, which described mothers' process of infant feeding: socio-cultural, health care system and personal factors. Culture was an umbrella theme influencing all aspects of infant feeding decisions. Mothers cited health care professionals' lack of cultural considerations and lack of relevance and practicality of infant feeding guidelines as the main reasons for ignoring infant feeding recommendations. Early introduction of pre-lacteal feeds and inappropriate types of foods fed to infants among immigrant/refugee Middle Eastern mothers in Canada is cause of concern. Involving trained language interpreters in health teams and educating health care staff on cultural competency may potentially increase maternal trust in the health care system and eventually lead to increased awareness of and adherence to best practices with infant feeding recommendations. © 2013 John Wiley & Sons Ltd.

Making the middle classes on shifting ground? Residential status, performativity and middle-class subjectivities in contemporary London.

Science.gov (United States)

Benson, Michaela; Jackson, Emma

2017-06-01

This paper argues that shifts in access to housing - both in relation to rental and ownership - disrupt middle-class reproduction in ways that fundamentally influence class formation. While property ownership has had a long association with middle-class identities, status and distinction, an increasingly competitive rental market alongside inflated property prices has impacted on expectations and anxieties over housing futures. In this paper, we consider two key questions: (1) What happens to middle-class identities under the conditions of this wider structural change? (2) How do the middle classes variously manoeuvre within this? Drawing on empirical research conducted in London, we demonstrate that becoming an owner-occupier may be fractured along lines of class but also along the axes of age, wealth and timing, particularly as this relates to the housing market. It builds on understandings of residential status and place as central to the formation of class, orienting this around the recognition of both people and place as mutable, emphasizing that changing economic and social processes generate new class positionalities and strategies for class reproduction. We argue that these processes are writ large in practices of belonging and claims to place, with wider repercussions within the urban landscape. © London School of Economics and Political Science 2017.

Middle mesial canal of the permanent mandibular first molars: an anatomical challenge directly related to the outcome of endodontic treatment.

To effectively clean and shape the mandibular permanent first molars it is mandatory to understand in detail their complex internal anatomy. The middle mesial canal is an additional canal located between the usual mesiobuccal and mesiolingual canals in the mesial root of mandibular first molars. The incidence of the middle mesial canal, its relationship with main canals of the mesial root and the possibility for it to be negotiated is an important practical issue in endodontics. To identify the presence of this canal is mandatory. Accordingly, a modified endodontic access, the use of the operating microscope and periapical radiographs in two different horizontal projections are indicated to enhance the long-term favorable outcome of the endodontic treatment.

Sedimentary Provenance Constraints on the Middle Jurassic to Late Cretaceous Paleogeography of the Sichuan Basin, SW China

Sedimentary provenance of the Middle Jurassic to Late Cretaceous sediments in the Sichuan Basin is constrained by sandstone petrology and detrital zircon U-Pb geochronology, which provides critical insights into mid-late Mesozoic paleogeographic evolution of the Sichuan Basin. Petrographic analyses of 22 sandstone samples indicate moderate to high mature sediments and are primarily derived from cratonic or recycled sources. U-Pb age data for the Middle Jurassic to Late Cretaceous detrital zircons generally show populations at 130-200, 200-330, 400-490, 680-890, 1730-1960, and 2360-2600 Ma, with up-section variations. The Middle Jurassic sediments contain a relatively high density of 1.85 and 2.5 Ga zircons and a low density of the 800 Ma zircons, which are consistent with derivation mainly from the Songpan-Ganzi terrane and the South Qinling belt, and secondarily from the Western Jiangnan Orogen. The Late Jurassic and Early Cretaceous sedimentation with a scattered age distribution shared common multiple-source to sink systems that were predominantly draining towards the south and southeast, but increasingly drained southward, and were later disrupted by a synchronous northeastward drainage capture. Late Cretaceous sediments have a distinct reduction in Block.

Science teachers naturally rely on their university science experiences as a foundation for teaching middle school science. This foundation consists of knowledge far too complex for the middle level students to comprehend. In order for middle school science teachers to utilize their university science training they must search for ways to adapt their college experiences into appropriate middle school learning experience. The criteria set forth above provide broad-based guidelines for translating university science laboratory experiences into middle school activities. These guidelines are used by preservice teachers in our project as they identify, test, and organize a resource file of hands-on inquiry activities for use in their first year classrooms. It is anticipated that this file will provide a basis for future curriculum development as the teacher becomes more comfortable and more experienced in teaching hands-on science. The presentation of these guidelines is not meant to preclude any other criteria or considerations which a teacher or science department deems important. This is merely one example of how teachers may proceed to utilize their advanced science training as a basis for teaching middle school science.

However, there are few trials that have determined the effect of antidiabetic treatment in an observational setting in these countries. Methods: This was a noninterventional study performed in Morocco in 2006–2007 and in the Middle East in 2005–2006 to observe the efficacy and safety of acarbose in patients with pretreated or untreated type 2 diabetes. Glycemic parameters (fasting blood glucose, one-hour postprandial blood glucose, and HbA1c were recorded within a 3-month period. The observation period included an initial visit at the start of acarbose therapy and up to three follow-ups. Results: Acarbose was effective in reducing glycemic parameters in patients from Morocco (n = 1082 and the Middle East (n = 1737. The mean one-hour postprandial blood glucose decreased by 35.5% to 165.4 ± 47.9 mg/dL in the Middle East and by 35.5% to 179.0 ± 49.9 mg/dL in Morocco. Mean fasting blood glucose decreased by 30.8% to 126.6 ± 34.2 mg/dL (Middle East and by 34.5% to 150.6 ± 47.1 mg/dL (Morocco. The absolute reduction in HbA1c was 1.3% in the Middle East (final value 7.4% and 1.0% in Morocco (final value 7.5%. Overall, 107 patients (Middle East and 26 patients (Morocco experienced minor drug-related adverse events, which were mainly gastrointestinal. The tolerability of acarbose was rated as very good/good by 80.8% in the Middle East and by 68.6% in Morocco. Conclusion: This study illustrates the efficacy and safety of acarbose in the treatment of type 2 diabetic patients in an observational setting.

To understand the prevalence and risk factors of non-suicidal self-injury in middle school students. 1312 middle school students of Pengzhou and Santai were selected to fill in a Risky Behavior Questionnaire for Adolescence (RBQ-A), Family Environment Scale (FES), Center for Epidemiological Survey, Depression Scale (CES-D), Adolescent Self-Rating Life Events Check List (ASLEC), Social Support Scale for Adolescents (SSSA) and self-administered questionnaire. In all the research subjects, 1288 were qualified for the study in April 2011 before the risk factors for non-suicidal self-injury were identified by logistic regression. In 1288 middle school students, 22.67% had a history of non-suicidal self-injury, with 22.70% in boys and 22.64% in girls. 63.36% of students had injured themselves through variously ways, more seen in boys (26.88%) than in girls (11.36%) who cut or burnt themselves. The scores of ASLEC and CES-D in non-suicidal self-injury group appeared higher than that in the control group and the score of SSSA was found higher in the control group. The main risk factors for non-suicidal self-injuries were family conflict, depressive emotion, negative life events and receiving less social support. The prevalence of non-suicidal self-injury among middle school students in Pengzhou was high, which called for more attention.

Conclusions: Respiratory tract infections in travellers/pilgrims returning to the UK from the Middle East are mainly due to rhinoviruses, influenza A, and influenza B. Whilst MERS-CoV was not detected in the 202 patients studied, heightened awareness of the possibility of MERS-CoV and continuous proactive surveillance are essential to rapidly identify cases of MERS-CoV and other seasonal respiratory tract viruses such as avian influenza, in patients presenting to hospital. Early identification and isolation may prevent outbreaks in nosocomial settings.

Consumption Behavior of Middle Strata in Times of Economic Crisis

2017-03-01

Full Text Available Based on the data of national representative surveys carried out by IS RAS in 2014-2016, the author presents analysis of consumption specifics in middle-income groups in times of current economic crisis. It is shown that although in modern Russian society middle income groups make up the majority of population, they cannot be directly correlated with the middle class defined in class theory framework. Middle-income groups are heterogeneous in different aspects, including their consumption specifics. Their standard of living remains quite modest, although it is significantly higher than the “survival standard”. New economic conditions led to widespread economy practices among them - primarily on consumption, followed by economy on hobbies and vacations. Economy practices also seriously affected middle-income strata investments in human capital – usage of paid educational and health services (this type of economy was more widespread among lower middle-income group than higher. Although representatives of the middle-income strata are quite actively using paid medical services (and relatively rarely – paid educational services, the reason for this more often lies in inaccessibility of free analogues rather than in search for the higher quality. Process of durables renewal in middle strata during the crisis was not as active, but their standard set of durable goods still widened over the past two years - primarily due to the relatively complex technological durables that they are gradually transferred from the category of innovation goods to the extended standard. In this regard, the upper middle income group successfully performs the function of the innovative consumer.

Balding, Cathy

2005-01-01

To strengthen the middle manager role in a hospital quality improvement (QI) program, with a view to increasing and sustaining organisational QI implementation. Case study based action research project, combining pre- and post-action quantitative and qualitative data collection, relating to a QI program intervention in an Australian metropolitan specialist teaching hospital. A model for enhancing the middle manager role in QI was developed and then implemented as the action over a 12-month period. Middle manager understanding and ownership of the QI program and organisational QI implementation significantly increased, although their perceived enjoyment of being involved in QI decreased. This case-study based action research project was limited to one organisation of a specific type - a large specialist metropolitan teaching hospital. The composition of the middle manager group, therefore, is necessarily limited to particular specialties. It is acknowledged that findings from case study and action research methodologies are limited in their generalisability, but assist in the development of knowledge and principles that can be adapted to different settings. This QI implementation model can increase levels of organisational QI implementation by effecting a positive change in middle manager attitude to and involvement in QI. There are many theories regarding the importance of the middle manager role in QI, but little empirical research into exactly what this role may be and how it may be strengthened. This research adds to the knowledge base, and provides clear steps for achieving increased staff involvement and QI implementation.

Full Text Available OBJECTIVE: To study the attitudes among general practitioners towards pneumococcal vaccination for middle-aged (50-64 and elderly population (over 65 in Hong Kong and the factors affecting their decision to advise pneumococcal vaccination for those age groups. DESIGN: Cross-sectional study of general practitioners in private practice in Hong Kong. PARTICIPANTS: Members of Hong Kong Medical Association delivering general practice services in private sector. MEASURING TOOL: Self-administered questionnaire. MAIN OUTCOME MEASURES: Intention to recommend pneumococcal vaccination, barriers against pneumococcal vaccination. RESULTS: 53.4% of the respondents would actively recommend pneumococcal vaccination to elderly patients but only 18.8% would recommend for middle-aged patients. Consultation not related to pneumococcal vaccine was the main reason for not recommending pneumococcal vaccine (43.6%. Rarity of pneumonia in their daily practice was another reason with 68.4% of respondents attending five or less patients with pneumonia each year. In multivariate analysis, factors such as respondents would get vaccination when reaching age 50 (ORm 10.1, and attending 6 pneumonia cases or more per year (ORm 2.28 were found to be associated with increasing likelihood for recommending vaccination to the middle-aged. While concerns of marketing a product (ORm 0.41, consultation not related to vaccination (ORm 0.45 and limited time (ORm 0.38 were factors that reduced the likelihood. CONCLUSION: Public policy is needed to increase the awareness of impact of pneumococcal pneumonia and the availability of preventive measures.

The knowledge about the aberrant internal carotid artery (ICA) in the middle ear is essential for clinicians, because a misdiagnosis of the aberrant ICA could have serious consequences such as excessive aural bleeding during a middle ear surgery. A 38-year-old woman presented with tinnitus and hearing difficulties of the left ear that had started 5 years ago. During otoscopy, an anteroinferior bluish mass was seen in the tympanic space. Computed tomography and magnetic resonance imaging demonstrated a left-side aberrant ICA with bony dehiscence of the carotid canal in the middle ear and a reduced diameter of the tympanic ICA. Herein we report a case of an aberrant ICA in the middle ear. We also review the literature regarding this important vascular anomaly of the temporal bone which may lead to disastrous surgical complications.

Eight cruises in the Amazon Basin were realized during the period between April (1982) and August (1984). Waters of main channel of the River Solimoes/Amazon and its tributaries were sampled and analysed for sup(18)0 content by mass spectrometry. A depth integrated sampler coupled to a variable speed hydraulic winch was used. The sampling was accomplished at different river stages, at upper Solimoes, middle and lower Amazon region. The δ sup(18) 0 values obtained in these reaches showed the same seasonal variation pattern. In the dry season, δ sup(18) 0 values become higher than in the rainy season. The isotopic variability in the region may be explained by the origin and dynamics of the water vapour. The spatial variation in δ sup(18) 0 values at the main channel was compared for high and low water stages; it showed an isotopic gradient of 0.052 and 0.048 sup(0)/∞ δ sup(18) 0/100 km, respectively.

Apatite Fission-Track Analysis of the Middle Jurassic Todos Santos Formation from Chiapas, Mexico.

2014-05-01

The Sierra de Chiapas (SCH), located in the south of Mexico, is a complex geological province that can be divided on four different lithological or tectonic areas: (1) the Chiapas Massif Complex (CMC); (2) the Central Depression; (3) the Strike-slip Fault Province, and (4) the Chiapas Fold-and-thrust Belt. The CMC mostly consists of Permian granitoids and meta-granitoids, and represents the basement of the SCH. During the Jurassic period red beds and salt were deposited on this territory, related to the main pulse of rifting and opening of the Gulf of Mexico. Most of the Cretaceous stratigraphy contains limestones and dolomites deposited on a marine platform setting during the postrift stage of the Gulf of Mexico rift. During the Cenozoic Era took place the major clastic sedimentation along the SCH. According the published low-temperature geochronology data (Witt et al., 2012), SCH has three main phases of thermo-tectonic history: (1) slow exhumation between 35 and 25 Ma, that affected mainly the basement (CMC) and is probably related to the migration of the Chortís block; (2) fast exhumation during the Middle-Late Miocene caused by strike-slip deformation that affects almost all Chiapas territory; (3) period of rapid cooling from 6 to 5 Ma, that affects the Chiapas Fold-and-thrust Belt, coincident with the landward migration of the Caribbean-North America plate boundaries. The two last events were the most significant on the formation of the present-day topography of the SCH. However, the stratigraphy of the SCH shows traces of the existence of earlier tectonic events. This study presents preliminary results of apatite fission-track (AFT) dating of sandstones from the Todos Santos Formation (Middle Jurassic). The analyses are performed with in situ uranium determination using LA-ICP-MS (e.g., Hasebe et al., 2004). The AFT data indicate that this Formation has suffered high-grade diagenesis (probably over 150 ºC) and the obtained cooling ages, about 70-60 Ma

The article is devoted to the study of the impact of the information economy on the formation of the middle class. The paper identifies factors contributing to the increase in the share of the middle class in the transition to the information economy. The positive synergetic influence of telecommunication technologies on the formation of the middle class is considered through a possibility of using virtual spaces for labor and educational activities, a possibility of obtaining high returns in the form of dividends on intellectual capital, a qualitative change in the structure of needs, an access to new types of information services, etc. Authors develop a complex model of research of the middle class in the information economy, differing from those available using an expanded list of criteria. In addition to such widely used criteria as income level, level of education and self-identification, the criterion "degree of involvement in the information society" was introduced. The study substantiates that the transition to the information economy made an access to information and communication technologies one of the most significant criteria for social differentiation of society. On the basis of the model, an econometric estimate of the middle class has been carried out, which makes it possible to reveal the share of the middle class in modern society, dynamics of its development, as well as multicollinearity between spending on education, the Gini coefficient, access to information and telecommunication technologies and the size of the middle class.

Full Text Available Personal and organizational performance is determined by commitment and both technical and general competencies, including leadership skills. Academia, however, mainly targets technical aspects in its curricular programs. On the other hand, the interdisciplinary and multi-sector nature of Nutrition necessitates high levels of collaboration between stakeholders. Leadership development is therefore required in Nutrition. This paper describes the endeavor made in Iran and the Middle-East region, aiming at building leadership capacity among nutrition professionals. The empowered human resource is expected to facilitate nutrition security at the national and regional levels.Since 2007, the development process of the initiative has begun through research, bench marking and consultation. The learning organizations, leadership from inside-out and transformational leadership frameworks have been employed as underpinning theories. Main topics have been self-awareness, effective communication, shared-visioning, trust building, creativity, and motivating. Outbound team building activities and coaching have also included.The 1st workshop of the Iranian Food and Nutrition Leadership Program (IFNLP was held in 2009 in Tehran. The experience expanded to the region as the Middle-East Nutrition Leadership Program (MENLP. The PhD Nutrition programs (at 4 leading Universities and Iranian Nutrition Society have been taken as other opportunity windows to develop leadership competencies. Biannual Iranian nutrition congresses have been used as the main media for advocacy purposes. High satisfaction rates obtained following each training activity.In short, the initiative on nutrition leadership development has received growing investment and positive feedback in Iran. Continuous improvement of the initiative, establishment of active alumni networks, building MENLP regional platform, and integrating a monitoring and evaluation system are required to increase investment

Full Text Available Within the framework of global leadership strategy, cooperation with regional powers turns out to be beneficial for the U.S. In the beginning of the XXI century, the United States relied on Turkey in the Middle East, but “neo-Ottoman” ambitions of Turkish government have caused such strong fears in Washington that in order to control its influence on the neighboring countries, the United States decided to limit the mediating role of Ankara in overall conflicts and dissentions in the region, by giving the prerogative to the other Sunni countries. At the same time, in order to deter the Sunni countries as a whole, US decided to soften its stance on Shiite Iran - a longtime political opponent. The situation in Iraq and the passive position of the U.S. in Syria allowed Shiite Iran to expand its influence in the region. The emerging Sunni-Shiite conflict in the Middle East provoked the rise of extremism in the region, as well as the armed conflict in Yemen. One of the main problems that threatens the regional and global security is a newly emerged radical terrorist organization ISIL, which to fight against, the U.S. provides a military and technical support to the Iraqi Kurds striving for their own sovereignty. The possibility of a rise of a Kurdish state in the region, in turn, poses a threat to the territorial integrity of Iran, Turkey, Syria and Iraq.

Climate change and water availability in the Middle East are important in understanding human adaptive capacities in the face of long-term environmental changes. The key role of water availability for sedentary and nomad populations in these arid to semiarid landscapes is understood, but the millennium-scale influence of hydrologic instability on vegetation dynamics, human occupation, and historic land use are unknown, which has led to a stochastic view of population responses and adaptive capacities to precipitation anomalies. Within the time-frame of the last two global climate events, the Medieval Climate Anomaly and the Little Ice Age, we report hydrologic instability reconstructed from pollen-derived climate proxies recovered near Tell Leilan, at the Wadi Jarrah in the Khabur Plains of northeastern Syria, at the heart of ancient northern Mesopotamia. By coupling climate proxies with archaeological-historical data and a pollen-based record of agriculture, this integrative study suggests that variability in precipitation is a key factor on crop yields, productivity, and economic systems. It may also have been one of the main parameters controlling human settlement and population migrations at the century to millennial timescales in the arid to semiarid areas of the Middle East. An abrupt shift to drier conditions at ca. AD 1400 is contemporaneous with a change from sedentary village life to regional desertion and nomadization (sheep/camel pastoralists) during the preindustrial era in formerly Ottoman realms, and thereby adds climate change to the multiple causes for Ottoman Empire "decline."

While vitamin D deficiency is well recognized in Middle Eastern women as a result of cultural norms of remaining covered, Middle Eastern men are an under-reported group. Vitamin D is now known to have multiple effects, including an impact on muscle function, thereby increasing the relevance for sportsmen. The aim of the present study was to evaluate serum 25-hydroxyvitamin D (25(OH)D) levels in young male Middle Eastern athletes. Cross-sectional study. Qatar Orthopaedic and Sports Medicine Hospital, Doha, Qatar. Ninety-three Middle Eastern men presenting to hospital for an annual screening undertook a blood test to evaluate their vitamin D status. Ninety-one per cent of athletes were found to be deficient in 25(OH)D (serum concentration Middle Eastern male athletes. Given the potentially significant long- and short-term effects of 25(OH)D deficiency, serum 25(OH)D evaluation should be part of the routine assessment in this region.

An overview is provided of Middle Eastern countries on the following topics; population change, epidemiological transition theory and 4 patterns of transition in the middle East, transition in causes of death, infant mortality declines, war mortality, fertility, family planning, age and sex composition, ethnicity, educational status, urbanization, labor force, international labor migration, refugees, Jewish immigration, families, marriage patterns, and future growth. The Middle East is geographically defined as Bahrain, Egypt, Iraq, Jordan, Kuwait, Lebanon, Oman, Qatar, Saudi Arabia, Syria, United Arab Emirates, Yemen, Gaza and the West Bank, Iran, Turkey, and Israel. The Middle East's population grew very little until 1990 when the population was 43 million. Population was about doubled in the mid-1950s at 80 million. Rapid growth occurred after 1950 with declines in mortality due to widespread disease control and sanitation efforts. Countries are grouped in the following ways: persistent high fertility and declining mortality with low to medium socioeconomic conditions (Jordan, Oman, Syria, Yemen, and the West Bank and Gaza), declining fertility and mortality in intermediate socioeconomic development (Egypt, Lebanon, Turkey, and Iran), high fertility and declining mortality in high socioeconomic conditions (Bahrain, Iraq, Kuwait, Qatar, Saudi Arabia, and the United Arab Emirates), and low fertility and mortality in average socioeconomic conditions (Israel). As birth and death rates decline, there is an accompanying shift from communicable diseases to degenerative diseases and increases in life expectancy; this pattern is reflected in the available data from Egypt, Kuwait, and Israel. High infant and child mortality tends to remain a problem throughout the Middle East, with the exception of Israel and the Gulf States. War casualties are undetermined, yet have not impeded the fastest growing population growth rate in the world. The average fertility is 5 births

STRATEGY IMPLEMENTATION STYLES OF MALAYSIAN, THAI AND HUNGARIAN MIDDLE MANAGERS

Full Text Available There is a need for more comparative empirical research that examines middle manager roles in strategic change. This paper reports a study of middle managers in two dynamic settings: the Asia/Pacific region – Malaysia and Thailand; and Central/Eastern Europe – Hungary. Results of 213 respondents across three countries indicate that middle managers from all three tend toward use of authoritarian management styles even in proactive strategic change situations. However, Hungarians are less likely to use these styles than Thai and Malaysian middle managers. For all three countries, managers with less work experience were found to have lower tendencies to use an authoritarian style of implementation. When top managers exhibit an aggressive strategic posture, middle-managers from all three countries are also less likely to use an authoritarian style.Firms that want to stay competitive in the global market place must continuously evolve by successfully accomplishing strategic change (Struckman & Yammarino 2003. Although senior managers are critical in leading the strategic change process, even the best-planned strategic changes will not achieve their full potential unless they are well implemented. Part of the strategic leadership responsibility, therefore, includes establishing a climate in which the organization's rank and file will experience both a positive attitude about change and the confidence to actively seek change opportunities (Kanter 2003. Research attention is bringing more insight into the important roles of middle-managers in this process of implementing strategic change (Balogun & Jenkins 2003; Floyd & Wooldridge, 1992, 1994; Wooldridge & Floyd 1990. Although there is little doubt that active support by middle managers is critical for the strategies to be well implemented (Guth & MacMillan 1986, there remain many important questions with regard to how middle managers participate in this process (Balogun 2003.The need for research

Water consumption acutely reduces meal energy intake (EI) among middle-aged and older adults. Our objectives were to determine if premeal water consumption facilitates weight loss among overweight/obese middle-aged and older adults, and to determine if the ability of premeal water consumption to reduce meal EI is sustained after a 12-week period of increased water consumption. Adults (n = 48; 55-75 years, BMI 25-40 kg/m(2)) were assigned to one of two groups: (i) hypocaloric diet + 500 ml water prior to each daily meal (water group), or (ii) hypocaloric diet alone (nonwater group). At baseline and week 12, each participant underwent two ad libitum test meals: (i) no preload (NP), and (ii) 500 ml water preload (WP). Meal EI was assessed at each test meal and body weight was assessed weekly for 12 weeks. Weight loss was ~2 kg greater in the water group than in the nonwater group, and the water group (beta = -0.87, P hypocaloric diet, consuming 500 ml water prior to each main meal leads to greater weight loss than a hypocaloric diet alone in middle-aged and older adults. This may be due in part to an acute reduction in meal EI following water ingestion.

The insulin and Brain-Derived Neurotrophic Factor (BDNF) signaling in the hippocampus promotes synaptic plasticity and memory formation. On the other hand, aging is related to the cognitive decline and is the main risk factor for Alzheimer's Disease (AD). The Protein-Tyrosine Phosphatase 1B (PTP1B) is related to several deleterious processes in neurons and emerges as a promising target for new therapies. In this context, our study aims to investigate the age-related changes in PTP1B content, insulin signaling, β-amyloid content, and Tau phosphorylation in the hippocampus of middle-aged rats. Young (3 months) and middle-aged (17 months) Wistar rats were submitted to Morris-water maze (MWM) test, insulin tolerance test, and molecular analysis in the hippocampus. Aging resulted in increased body weight, and insulin resistance and decreases learning process in MWM. Interestingly, the middle-aged rats have higher levels of PTP-1B, lower phosphorylation of IRS-1, Akt, GSK3β, mTOR, and TrkB. Also, the aging process increased Tau phosphorylation and β-amyloid content in the hippocampus region. In summary, this study provides new evidence that aging-related PTP1B increasing, contributing to insulin resistance and the onset of the AD. Copyright © 2018 Elsevier Inc. All rights reserved.

Middle ear osteoma causing progressive facial nerve weakness: a case report.

Curtis, Kate; Bance, Manohar; Carter, Michael; Hong, Paul

2014-09-18

Facial nerve weakness is most commonly due to Bell's palsy or cerebrovascular accidents. Rarely, middle ear tumor presents with facial nerve dysfunction. We report a very unusual case of middle ear osteoma in a 49-year-old Caucasian woman causing progressive facial nerve deficit. A subtle middle ear lesion was observed on otoscopy and computed tomographic images demonstrated an osseous middle ear tumor. Complete surgical excision resulted in the partial recovery of facial nerve function. Facial nerve dysfunction is rarely caused by middle ear tumors. The weakness is typically due to a compressive effect on the middle ear portion of the facial nerve. Early recognition is crucial since removal of these lesions may lead to the recuperation of facial nerve function.

Eighteen patients with chronic otitis media, middle ear cholesteatoma, and postoperative inflammatory diseases of the middle ear underwent high resolution computerized tomography (CT) and magnetic resonance imaging (MRI) before surgical exploration of the middle ear. Results showed that CT provides higher detail resolution in middle ear structures, but provides limited density resolution in displaying inflammatory soft tissue lesions. By contrast, MRI differentiates among soft tissue lesions such as fluid-filled spaces, granulation tissues, and cholesteatomatous debris. Cholesterin granulomas show a particularly characteristic signal pattern with a very high intensity area in both T1 and T2 weighted images. It is concluded that MRI is useful in differentiating soft tissue density masses when used in conjunction with CT in middle ear inflammatory diseases. (author)

Biofilms have been implicated in the development of several chronic upper respiratory tract infections. Role of bacterial biofilms has been well studied in the pathogenesis of chronic rhinosinusitis. However, its impact on development of middle ear effusion is still a matter of debate. To study the extent of surface adenoid biofilm and evaluate its role in the pathogenesis of chronic otitis media with effusion in children. The study was carried out on 40 children in Alexandria Main University Hospital between 1 and 16 years of age without sex predilection, who were divided into two groups. The first group (20 children) had otitis media with effusion associated with adenoid hypertrophy, whereas the second group (20 children) had adenoid hypertrophy without middle ear effusion. Adenoidectomy with ventilation tube insertion was done for group 1 cases, whereas, only Adenoidectomy was done for group 2 cases. The samples were processed for the detection of biofilms by scanning electron microscopy. The biofilm formation was graded according to extension. Biofilm formation was detected on all samples for group 1. Adenoids removed from patients with otitis media with effusion had higher-grade biofilm formation than the other group (P 0.0001). No correlation was found between adenoid size and biofilm formation. In pediatric population, adenoid surface biofilm formation may be involved in the pathogenesis otitis media with effusion.

Poag, C.W.; Commeau, J.A.

1995-01-01

The Paleocene to Middle Miocene sedimentary fill of the southwestern Salisbury Embayment contains a fragmental depositional record, interrupted by numerous local diastems and regional unconformities. Using planktic foraminiferal biostratigraphy, 15 unconformity-bounded depositional units have been identified, assigned to six formations and seven alloformations previously recognized in the embayment. The units correlate with second- and third-order sequences of the Exxon sequence stratigraphy model, and include transgressive and highstand systems tracts. Alloformation, formation, and sequence boundaries are marked by abrupt, scoured, burrowed, erosional surfaces, which display lag deposits, biostratigraphic gaps, and intense reworking of microfossils above and below the boundaries.Paleocene deposits represent the upper parts of upper Pleocene Biochronozones P4 and P5, and rest uncomformably  on Cretaceous sedimentary beds of various ages (Maastrichtian to Albian). Lower Eocene deposits represent parts of Biochronozones P6 and P9. Middle Eocene strata represent mainly parts of Biochronozones P11, P12, and P14. Upper Eocene sediments include parts of Biochronozones P15, P16, and P17. Oligocene deposits encompass parts of Biochronozones. N4b to N7 undifferentiated, P21a, and, perhaps, N4a. Lower Miocene deposits encompass parts of Biochronozones N4b to N7 undifferentiated. Middle Miocene strata represent mainly parts of Biochronorones N8, N9, and N10.Nine plates of scanning electron micrographs illustrate the principal planktic foraminifera used to establish the biostratigraphic framework. Two new informal formine of Praeterenuitella praegemma Li, 1987, are introduced.

Searching the Origins of Political Discourse – An Intertextual Analysis of Ronald Reagan’s Farewell Speech

Directory of Open Access Journals (Sweden)

Małgorzata Szudrowicz-Garstka

2014-11-01

Full Text Available The aim of the investigation is to present the relation between political and religious discourse on the basis of intertextual elements linking the two types of discourse. A presidential speech by Ronald Reagan, delivered in the Oval Office at the White House on January 11, 1983, constitutes the material for the research. The emphasis of the study is placed on the fragments referring to “the shining city upon the hill”, i.e. to the most frequently used metaphor by the president. The roots of the afore mentioned parts belong to religious discourse. They can be found primarily in a sermon by John Winthrop – one of the Puritans – who came to America in 1630. Nevertheless, it is not the sole source of references. While preparing his “Modell of Christian Charity”, John Winthrop referred to the Bible. Words considering “the city upon the hill” are to be found in the Gospel (Mt 5, 14. The analysed fragment of the “Sermon on the Mount”, i.e., “You are the light of the world. A city built on a hill cannot be hidden (…” deals with advice on the lifestyle of Jesus’s followers and obviously serves as an example of religious discourse as well.

2018-05-01

Atrial fibrillation (AF) is the commonest persistent cardiac arrhythmia with an estimated incidence rate of between 1.5-2% and an important cause of strokes. Few epidemiological studies and clinical trials on the management of AF have been conducted outside Europe and North America. These gaps in our understanding of AF likely lead to sub-optimal management of patients with AF in the rest of the world. Areas covered: We discuss the epidemiology, treatment and clinical outcomes for AF in the Middle East after systematic review of published work for AF from the Middle East. We also discuss important clinical trials on AF conducted in the West in the same period to help contextualize our findings. Expert commentary: The few available Middle East studies suggest important epidemiological differences between Middle Eastern and Western AF populations. In particular, the Middle Eastern AF population is younger and have more co-morbidities than patients in the West. We find that significant numbers of moderate to high risk patients with AF are either undertreated or untreated placing them at increased risk of complications such as stroke. More studies in the Middle Eastern population are required to aid the development of region-specific clinical guidelines to improve patient care.

Reports from the French Ministry of Education warn of a decrease in the use of school food services, especially in sensitive urban areas. They also suggest that this decline has led to cases of malnutrition. This article describes the characteristics of the current supply of school meals and measures the evolution of demand observed between 1992 and 1996 in relation to the economic situation of students' families. The study was carried out in 3 departments in France: Doubs, Herault, and Val de Marne. The administrators of all public and private middle and high schools in the 3 departments received a questionnaire asking them to describe the services offered in their cafeterias and to provide the corresponding statistical and accounting data. External food services near the schools were also taken into account. Seventy-nine percent of schools responded to the survey. Concerning the services offered, 91% of schools have their own cafeterias, of which 81% are managed by the schools. Concerning the evolution of utilisation, a significant decrease in the number of meals served in seen in middle schools. On the other hand, high schools have observed stable utilisation. The positive changes in utilisation are linked, in middle schools, to characteristics of the schools' internal food services (self-service, choice of main courses, modulation of seats). In high schools, positive changes in the utilisation of school services are linked to the lack of external food services near the schools. As middle schools and high schools control the logistics and management of food services offered to students, they are potentially in a position to influence a policy on this issue. The evolution in utilisation is very different among departments and between middle and high schools. While economic precariousness has a negative structural effect on utilisation, it doesn't seem to be a major factor in the evolution of the decrease observed over the past few years.

2016-09-01

Full Text Available Objectives: The accessory middle turbinate, a rare anatomical variation of the nasal cavity, have been systematically studied in adults. Presence of accessory middle turbinate and its clinical significance in a child has not been reported. We describe clinical appearance and radiologic features of accessory middle turbinate in a child. Methods: Retrospective chart review. Results: A 3-year-old boy presented to the otolaryngology clinic for evaluation of recurrent epistaxis. Anterior rhinoscopy revealed moist nasal mucosa without inflammation and bilateral prominent blood vessels on the anterior nasal septum. Nasal endoscopy showed turbinate like protuberances in bilateral middle meatus. CT images documented accessory middle turbinate in the bilateral nasal cavity. Conclusion: Otolaryngologists should be cognizant of anatomical variations of middle turbinate to achieve correct diagnosis and avoid potential complications during surgical management.

Review of the Dinosaur Remains from the Middle Jurassic of Scotland, UK

Full Text Available Dinosaurs are rare from the Middle Jurassic worldwide. The Isle of Skye, is the only place in Scotland thus far to have produced dinosaur remains. These remains consist mainly of footprints, but also several bones and teeth. These Bajocian and Bathonian remains represent an important collection of a basal eusauropod, early examples of non-neosauropod and possible basal titanosauriform eusauropods, and theropod remains that may belong to an early coelurosaur and a possible megalosaurid, basal tyrannosauroid, or dromaeosaurid. The footprints from here also suggest a rich and diverse dinosaur fauna for which further better diagnosable remains are likely to be found.

Chronic obstructive pulmonary disease (COPD) is one of the leading causes of death globally. In addition to the mortality associated with it, people with COPD experience significant morbidity, making this set of conditions a major public health concern. Infections caused by influenza virus are a preventable cause of morbidity and vaccination has been shown to be effective. The evidence of their benefit in persons with COPD mainly comes from high-income countries where influenza vaccination is used in routine practice, but little is known about the effectiveness, cost-effectiveness, and scalability of vaccination in low- and middle-income countries. We therefore systematically reviewed and present evidence related to vaccination against influenza in persons with COPD with a special focus on studies from low- and middle-income countries (LMICs). Available data from 19 studies suggest that the use of influenza vaccine in persons with COPD is beneficial, cost-effective, and may be relevant for low- and middle-income countries. Wider implementation of this intervention needs to take into account the health care delivery systems of LMICs and use of prevalent viral strains in vaccines to be most cost effective.

Toshiba Corp. newly developed a natural voice synthesis system, TOS Drive TTS (TOtally speaker Driven Text-To-Speech) system, in which natural high-quality read-aloud is greatly improved, and also developed as its application a voice synthesis middle ware. In the newly developed system, using as a model a narrator's voice recorded preliminarily, a metrical control dictionary is automatically learned that reproduces the characteristics of metrical patters such as intonation or rhythm of a human voice, as is a voice bases dictionary that reproduces the characteristics of a voice quality, enabling natural voice synthesis to be realized that picks up human voice characteristics. The system is high quality and also very compact, while the voice synthesis middle ware utilizing this technology is adaptable to various platforms such as MPU or OS. The system is very suitable for audio response in the ITS field having car navigation systems as the core; besides, expanded application is expected to an audio response system that used to employ a sound recording and reproducing system.

Issues in Health Care of Middle Eastern Patients

Science.gov (United States)

Lipson, Juliene G.; Meleis, Afaf I.

1983-01-01

Relationships between Middle Eastern patients and Western health care professionals are often troubled by mutual misunderstanding of culturally influenced values and communication styles. Although Middle Easterners vary ethnically, they do share a core of common values and behavior that include the importance of affiliation and family, time and space orientations, interactional style and attitudes toward health and illness. Problems in providing health care involve obtaining adequate information, “demanding behavior” by a patient's family, conflicting beliefs about planning ahead and differing patterns of communicating grave diagnoses or “bad news.” There are guidelines that will provide an understanding of the cultural characteristics of Middle Easterners and, therefore, will improve rather than impede their health care. A personal approach and continuity of care by the same health care professional help to bridge the gap between Middle Eastern cultures and Western medical culture. In addition, periodic use of cultural interpreters helps ameliorate the intensity of some cultural issues. PMID:6364575

Radiologic evaluation of right middle lobe collapse

International Nuclear Information System (INIS)

Kwun, Dae Young; Kim, Jong Deok; Kim, Jong Chul

1989-01-01

There are many pathogenetic factors for collapse of right middle lobe; profuse peribronchial clustering of lymph nodes about the right middle lobe bronchus, poor drainage of the bronchus because of its acute angle of take-off from the intermediate bronchus, and the isolation of this small lobe from the right upper and lower lobes, and thus from the aerating effects of collateral ventilation. Retrospectively we reviewed 36 cases of right of right middle lobe collapse of which causes were confirmed by histopathologic or bronchographic findings during the recent 6 years from March 1983 to February 1988 at Inje College Pusan Paik Hospital, and obtained the following results: 1. Male to female ratio was 1:1:4,and peak incidence (64%) was in the fifth and sixth decades with the mean age of 51.1 years. 2. Bronchiectasis was the most common cause (30.6%), and the others were chronic bronchitis (25.0%), pulmonary tuberculosis (19.4%), lung cancer (16.7%), and non-specific inflammatory disease (8.3%). This suggests benign disease is 5 times more common cause of right middle lobe collapse than lung cancer. 3. Among the plain chest radiolograph findings, obliteration of right cardiac border and triangular radiopaque density were the most frequent findings(77.8% in each) and the next was downward and anterior displacement of minor and major fissures (55.6%) 4. Bronchography was done in 11 cases; bronchiectasis was found in 8 cases and chronic bronchitis in 3 cases. Right middle lobe bronchus was obstructed in 2 cases of chronic bronchitis. 5. Chest CT scan was performed in 4 cases of lung cancer, 2 of non-specific inflammatory disease, and 1 of pulmonary tuberculosis: all of lung cancer revealed hilar mass, budged or lobulated fissures, in homogenous density, and mediastinal lymph node enlargement, and all benign disease showed homogenous density and flat to concave fissures. Right middle lobar bronchus narrowing was seen in 5 cases and its obstruction in 2 cases

LINEs Contribute to the Origins of Middle Bodies of SINEs besides 3′ Tails

Science.gov (United States)

2018-01-01

Abstract Short interspersed elements (SINEs), which are nonautonomous transposable elements, require the transposition machinery of long interspersed elements (LINEs) to mobilize. SINEs are composed of two or more independently originating parts. The 5′ region is called the “head” and is derived mainly from small RNAs, and the 3′ region (“tail”) originates from the 3′ region of LINEs and is responsible for being recognized by counterpart LINE proteins. The origin of the middle “body” of SINEs is enigmatic, although significant sequence similarities among SINEs from very diverse species have been observed. Here, a systematic analysis of the similarities among SINEs and LINEs deposited on Repbase, a comprehensive database of eukaryotic repeat sequences was performed. Three primary findings are described: 1) The 5′ regions of only two clades of LINEs, RTE and Vingi, were revealed to have contributed to the middle parts of SINEs; 2) The linkage of the 5′ and 3′ parts of LINEs can be lost due to occasional tail exchange of SINEs; and 3) The previously proposed Ceph-domain was revealed to be a fusion of a CORE-domain and a 5′ part of RTE clade of LINE. Based on these findings, a hypothesis that the 5′ parts of bipartite nonautonomous LINEs, which possess only the 5′ and 3′ regions of the original LINEs, can contribute to the undefined middle part of SINEs is proposed.

The relationship of mentoring on middle school girls' science-related attitudes

Science.gov (United States)

Clark, Lynette M.

This quantitative study examined the science-related attitudes of middle school girls who attended a science-focused mentoring program and those of middle school girls who attended a traditional mentoring program. Theories related to this study include social cognitive theory, cognitive development theory, and possible selves' theory. These theories emphasize social and learning experiences that may impact the science-related attitudes of middle school girls. The research questions examined the science-related attitudes of middle school girls who participate in a science-related mentoring program. The hypotheses suggested that there are significant differences that exist between the attitudes of middle school female participants in a science-related mentoring program and female participants in a traditional mentoring program. The quantitative data were collected through a survey entitled the Test of Science-Related Attitudes (TOSRA) which measures science-related attitudes. The population of interest for this study is 11-15 year old middle school girls of various racial and socio-economic backgrounds. The sample groups for the study were middle school girls participating in either a science-focused mentoring program or a traditional mentoring program. Results of the study indicated that no significant difference existed between the science-related attitudes of middle school girls in a science-related mentoring program and the attitudes of those in a traditional mentoring program. The practical implications for examining the concerns of the study would be further investigations to increase middle school girls' science-related attitudes.

This study aimed to examine the effects of self-selected low-intensity walking on an active workstation on executive functions (EF) in young and middle-age adults. Using a within-subjects design, 32 young (20.6 ± 2.0 yr) and 26 middle-age (45.6 ± 11.8 yr) adults performed low-intensity treadmill walking and seated control conditions in randomized order on separate days, while completing an EF test battery. EF was assessed using modified versions of the Stroop (inhibition), Sternberg (working memory), Wisconsin Card Sorting (cognitive flexibility), and Tower of London (global EF) cognitive tasks. Behavioral performance outcomes were assessed using composite task z-scores and traditional measures of reaction time and accuracy. Average HR and step count were also measured throughout. The expected task difficulty effects were found for reaction time and accuracy. No significant main effects or interactions as a function of treadmill walking were found for tasks assessing global EF and the three individual EF domains. Accuracy on the Tower of London task was slightly impaired during slow treadmill walking for both age-groups. Middle-age adults displayed longer planning times for more difficult conditions of the Tower of London during walking compared with sitting. A 50-min session of low-intensity treadmill walking on an active workstation resulted in accruing approximately 4500 steps. These findings suggest that executive function performance remains relatively unaffected while walking on an active workstation, further supporting the use of treadmill workstations as an effective approach to increase physical activity and reduce sedentary time in the workplace.

2017-01-01

Right middle lobe (RML) syndrome is defined as recurrent or chronic obstruction or infection of the middle lobe of the right lung. Nonobstructive causes of middle lobe syndrome include inflammatory processes and defects in the bronchial anatomy and collateral ventilation. We report on 2 case patients with RML syndrome, one due to infection with Mycobacterium avium complex followed by M asiaticum infection and the other due to allergic bronchopulmonary aspergillosis. A history of atopy, asthma, or chronic obstructive pulmonary disease has been reported in up to one-half of those with RML. The diagnosis can be made by plain radiography, computed tomography, and bronchoscopy. Medical treatment consists of bronchodilators, mucolytics, and antimicrobials. Patients whose disease is unresponsive to treatment and those with obstructive RML syndrome can be offered surgical treatment.

The dose reduction is a strategic purpose for EDF in link with the stakes of, nuclear acceptability, respect of regulation and productivity gains. This consists not only in improving the reactor shutdown organization (time spent in control area, biological shielding,...) but also in improving the radiological state of the unit and the efficiency of the source term reduction operations. Since 2003, EDF has been running an innovative project called 'Source Term Reduction' federating the different EDF research and engineering centers in order to: - participate to the long term view about Radiological Protection issues (international feedback analyses), - develop contamination prediction tools (OSCAR software) suitable for the industrial needs (operating units and EPR design), - develop scientific models useful for the understanding of contamination mechanisms to support the strategic decision processes, - carry on with updating and analyzing of contamination measurements feedback in corrosion products (EMECC and CZT campaigns), - carry on with the operational support at short or middle term by optimizing startup and shutdown processes, pre-oxidation or and by improving purification efficiency or material characteristics. This paper will show in a first part the main 2011 results in occupational exposure (collective and individual dose, RCS index...). In a second part, an overview of the main EDF outcomes of the last 3 years in the field of source term reduction will be presented. Future developments extended to contamination issues in EDF NPPs will be also pointed out in this paper. (authors)

Variation of precipitation for the last 300 years over the middle and lower reaches of the Yellow River

Institute of Scientific and Technical Information of China (English)

ZHENG; Jingyun; HAO; Zhixin; GE; Quansheng

2005-01-01

The precipitation at 17 stations over the middle and lower reaches of the Yellow River is reconstructed during the period of 1736―1910, using the snow and rainfall records in the Qing Dynasty, together with the instrumental observation data of precipitation and farmland soil moisture content. The soil physics model related to rainfall infiltration and the surface water balance equation are taken as main reconstruction methodology. The field infiltration experiment by artificial rainfall is conducted to check the reliability. And the precipitation series over the middle and lower reaches of the Yellow River and its 4 sub-regions are established, going back to 1736. Analysis of the time series indicates that the abrupt change of precipitation from high to low occurs around 1915 over the middle and lower reaches of the Yellow River. During the three periods of 1791―1805, 1816―1830 and 1886―1895, the precipitation is markedly higher than the mean of the series. While both the periods of 1916―1945 and 1981―2000 are characterized by less precipitation. Three periodicities of 22―25a, 3.9a and 2.7a are shown in the precipitation fluctuation over the middle and lower reaches of the Yellow River. Moreover, the periodical signal of 22―25a becomes weaker and weaker since the abrupt change of 1915 and disappears in the late 1940s, and then the periodical signal of 35―40a appears instead.

Many patients with type 2 diabetes find it difficult to maintain good glycemic control. Undesirable glycemic control occurs greatly due to deficiencies of nutritional knowledge and difficulty in obtaining dietary prescriptions. The late middle-aged and elder individuals are the main populations that are affected by type 2 diabetes. The main purpose of this study was to investigate whether intensive nutrition education would make benefits for late middle-aged patients with type 2 diabetes. 196 patients between 50 to 65 years old meeting type 2 diabetes criteria and eligible for the program were included in a single-blinded, 30-day centralized management of an education program in China. Participants in the program were randomly divided into a usual nutrition education group or an intensive nutrition education group. The usual nutrition education group was used as a control group and received only basic health advice and principles of diabetic diets at the beginning and the end of the study. Participants in the intensive nutrition education group were arranged to receive intensive nutritional lectures about diabetes for 30 days. The primary outcomes were the changes in weight, body mass index (BMI), fasting plasma glucose (FPG), 2-h postprandial plasma glucose (PG), glycosylated hemoglobin (HbA1c), total glycerin (TG), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-c), and low-density lipoprotein cholesterol (LDL-c). After 30 days of intervention, FPG, PG, and HbA1c in the treatment group decreased significantly than the control group (p nutrition education group. However, there was no statistical significance between groups. Intensive nutrition education has significant effects on blood glucose control in late middle-aged adults with type 2 diabetes. Intensive education can cultivate good diet habits and increase physical activity, which are important for diabetes patients in the short and long terms. These findings may contribute to improving

Aerosol optical depth trend over the Middle East

KAUST Repository

Klingmüller, Klaus

2016-04-22

We use the combined Dark Target/Deep Blue aerosol optical depth (AOD) satellite product of the moderate-resolution imaging spectroradiometer (MODIS) collection 6 to study trends over the Middle East between 2000 and 2015. Our analysis corroborates a previously identified positive AOD trend over large parts of the Middle East during the period 2001 to 2012. We relate the annual AOD to precipitation, soil moisture and surface winds to identify regions where these attributes are directly related to the AOD over Saudi Arabia, Iraq and Iran. Regarding precipitation and soil moisture, a relatively small area in and surrounding Iraq turns out to be of prime importance for the AOD over these countries. Regarding surface wind speed, the African Red Sea coastal area is relevant for the Saudi Arabian AOD. Using multiple linear regression we show that AOD trends and interannual variability can be attributed to soil moisture, precipitation and surface winds, being the main factors controlling the dust cycle. Our results confirm the dust driven AOD trends and variability, supported by a decreasing MODIS-derived Ångström exponent and a decreasing AERONET-derived fine mode fraction that accompany the AOD increase over Saudi Arabia. The positive AOD trend relates to a negative soil moisture trend. As a lower soil moisture translates into enhanced dust emissions, it is not needed to assume growing anthropogenic aerosol and aerosol precursor emissions to explain the observations. Instead, our results suggest that increasing temperature and decreasing relative humidity in the last decade have promoted soil drying, leading to increased dust emissions and AOD; consequently an AOD increase is expected due to climate change.

2008-01-01

Traditional bone setting is a practice that is common in our environment. This is a community based survey of opinions concerning orthodox and traditional fracture management in four states of the middle belt of Nigeria. We set out to ascertain the factors influencing preference of treatment of fractures among populations in the middle belt of Nigeria. A community based questionnaire survey of randomly selected adults regarding preference of choice of treatment between orthodox and traditional fracture management. One hundred and eighty-six questionnaires were found analyzable with a male to female ratio of 2:1. There was a preponderance of preference for orthodox fracture management (70.4%). Decisions were mainly collegiate, outside the influence of the individual; only 9.9% decided to attend traditional bone setters on their own. Reasons adduced for preference of traditional bone setters were incongruous and inconsistent. A fixated cultural outlook was recognized as being the motivating factor for patronage of traditional bone setters. Need for enlightenment campaign of the public against patronage of traditional bone setters is emphasized. A gradual phasing out of traditional bone setting with a road map towards making orthodox fracture management available to all is advocated.

The exquisite preservation of fossilized Metasequoia trees that grew near 80°N latitude during the middle Eocene (ca. 45 Ma) in Nunavut, Canada, allowed for δD and δ18O analyses of cellulose, techniques previously restricted to wood <30,000 yr old. From the isotopic results, we determined that the middle Eocene Arctic atmosphere contained ˜2× the water found in the region's atmosphere today. This water vapor contributed to a middle Eocene greenhouse effect that insulated the polar region during dark polar winters.

Background. Sleep difficulties, including insufficient sleep and inadequate sleep hygiene, have been prevalent among children. Sleep deprivation can lead to poor grades, sleepiness, and moodiness. We undertook this study to assess the prevalence of sleep abnormalities among elementary and middle school students in South Texas and how the groups compare with one another. Method. After approval from the appropriate school district for a sleep education program, a baseline survey was taken of elementary and middle school students, using the Children's Sleep Habit Questionnaire-Sleep Self-Report Form, which assessed the domains of bedtime resistance, sleep onset delay, sleep anxiety, sleep duration, night awakening, and daytime sleepiness. Results. The survey was completed by 499 elementary and 1008 middle school children. Trouble sleeping was reported by 43% in elementary school, compared with 29% of middle school children. Fifty percent of middle school children did not like sleeping, compared with 26% in elementary school. Bedtime resistance, sleep onset delay, and nighttime awakening were more common among elementary school students. Daytime sleepiness was more common among the middle school children when compared to elementary school children. Conclusions. Sleep abnormalities are present in elementary school children with changes in sleep habits into middle school.

Many studies have reported brain volume changes in smokers. However, the volume differences of grey matter (GM) and white matter (WM) in young and middle-aged male smokers with different lifetime tobacco consumption (pack-years) remain uncertain. To examine the brain volume change, especially whether more pack-years smoking would be associated with smaller gray matter and white matter volume in young and middle-aged male smokers. We used a 3T MR scanner and performed Diffeomorphic anatomical registration through exponentiated lie algebra (DARTEL)-based voxel-based morphometry on 53 long-term male smokers (30.72 ± 4.19 years) and 53 male healthy non-smokers (30.83 ± 5.18 years). We separated smokers to light and heavy smokers by pack-years and compared brain volume between different smoker groups and non-smokers. And then we did analysis of covariance (ANCOVA) between smokers and non-smokers by setting pack-years as covariates. Light and heavy smokers all displayed smaller GM and WM volume than non-smokers and more obviously in heavy smokers. The main smaller areas in light and heavy smokers were superior temporal gyrus, insula, middle occipital gyrus, posterior cingulate, precuneus in GM and posterior cingulate, thalamus and midbrain in WM, in addition, we also observed more pack-years smoking was associated with some certain smaller GM and WM volumes by ANCOVA. Young and middle-aged male smokers had many smaller brain areas than non-smokers. Some of these areas' volume had negative correlation with pack-years, while some had not. These may due to different pathophysiological role of smokings. © 2015 John Wiley & Sons Ltd.

The aim of this study was to profile and compare the middle ear microbiomes of human subjects with and without chronic otitis media. Prospective multicenter cohort study. All consecutive patients undergoing tympanoplasty surgery for chronic otitis media or ear surgery for conditions other than otitis media were recruited. Sterile swab samples were collected from the middle ear mucosa during surgery. The variable region 4 of the 16S rRNA gene in each sample were amplified using region-specific primers adapted for the Illumina MiSeq sequencer (Illumina, CA, USA)). The sequences were subjected to local blast and classified using Metagenome@KIN (World Fusion, Tokyo, Japan). In total, 155 participants were recruited from seven medical centers. Of these, 88 and 67 had chronic otitis media and normal middle ears, respectively. The most abundant bacterial phyla on the mucosal surfaces of the normal middle ears were Proteobacteria, followed by Actinobacteria, Firmicutes, and Bacteroidetes. The children and adults with normal middle ears differed significantly in terms of middle ear microbiomes. Subjects with chronic otitis media without active inflammation (dry ear) had similar middle ear microbiomes as the normal middle ears group. Subjects with chronic otitis media with active inflammation (wet ear) had a lower prevalence of Proteobacteria and a higher prevalence of Firmicutes than the normal middle ears. The human middle ear is inhabited by more diverse microbial communities than was previously thought. Alteration of the middle ear microbiome may contribute to the pathogenesis of chronic otitis media with active inflammation. 2b.

Recruiting middle school students into nursing: An integrative review.

Science.gov (United States)

Williams, Cheryl

2017-10-27

Middle school students interested in nursing need clarification of the nursing role. Students choose nursing as a career because they want to help others, yet they are often unaware of the need to for arduous secondary education preparation to become a nurse. Middle school students, if not properly exposed to the career during their formative years, may choose another career or not have enough time for adequate nursing school preparation. This integrative review examined seven studies from years 2007 to 2016, which utilized various recruitment strategies to increase the awareness of nursing as a career in middle school and address the need for academic rigor. Implications of the review: there is a need for collaboration between nurses and school counselors to design more robust longitudinal studies of middle school interventions for students interested in nursing as a career. © 2017 Wiley Periodicals, Inc.

The aim of this study was to evaluate detailed changes of gastroesophageal reflux disease (GERD) in children before and after laparoscopic Nissen fundoplication (LNF) utilizing esophageal combined pH-multichannel intraluminal impedance (pH/MII) measurements. Thirteen patients with neurological impairment, who received laparoscopic Nissen fundoplication (LNF) owing to refractory pathological GERD, were enrolled in this study. 24h pH/MII was conducted in all patients before and one year after LNF. Each parameter of the pH/MII was evaluated and compared each other. Both the mean pH index and bolus exposure index after LNF were significantly lower than those before LNF. The mean numbers of total and nonacid reflux episodes after LNF were significantly lower than those before LNF. The mean numbers of total, acid and nonacid proximal reflux episodes after LNF were significantly lower than those before LNF. The mean baseline impedance values from Z3 to Z6 after LNF were significantly higher than those before LNF. The present study provides new insights into the effects of LNF in pediatric patients, which prevents mainly acid reflux episodes from rising to the proximal esophagus, and is expected to improve the mucosal integrity up to the middle esophagus.

The field of reproductive medicine witnessed a breakthrough in September 2014 with the first successful live birth post uterine transplantation. This success represents the culmination of decades' worth of research on infertility and reproductive medicine. This subject of infertility gathers special attention in the Middle East, as childbearing is given paramount importance in the family unit. And as with any new medical advancement, Middle Eastern people look to their religious authorities for guidance. This paper describes the various ethical quandaries related to uterine transplantation, from a perspective of the religious and societal factors that are unique to the Middle East, and embeds them within the conversation of its alternative solutions. © 2015 John Wiley & Sons Ltd.

Objective: To study stress distribution and displacement of abutment of middle implant-natural teeth fixed bridge under different loading. Methods: The stress distribution and displacement of abutment were studied and analyzed by means of three-dimensional finite element when different loading was applied. Results: The biggest stress of middle implant was 4-5 times as big as that of natural teeth. Under concentrated vertical loading, the biggest stress of implant was about 2 times higher than that under dispersed vertical loading. There was no significant difference of biggest stress on the implant between concentrated oblique loading and dispersed oblique loading. The biggest stress of implant under oblique loading was 3 times as big as that under dispersed vertical loading. The biggest stress of natural teeth under dispersed loading was lower than that under concentrated loading. The maximum displacement of implant in occlusal-gum direction was great lower than that of natural teeth. Both in buccal-lingual direction and medial-distal direction, the displacement of implant were about equal to that of natural teeth. Conclusion: The oblique loading is the main force to destroy the middle implant-natural teeth fixed bridge. The lean of cusp should be reduced. The abnormally high occlusal points should be deleted. The bite points should be well distributed. The fixed bridge is feasible. (authors)

A case of middle ear mass in a young female from Ireland is described, who presented with left ear hearing loss and intermittent bloody discharge from the same ear. Examination under microscope revealed occlusive polyp in the left ear and a biopsy had been taken under general anaesthesia. Histopathology report described an adenoma \\/ carcinoid tumour of the middle ear confirmed by positive immunohistochemical staining. CT temporal bones revealed the extension of the disease. The patient underwent left tympanotomy and excision of the tumour. In general, these tumours are regarded as benign but may be mistaken for adenocarcinomas because of their histological heterogenecity.

Full Text Available BACKGROUND Although pulmonary tuberculosis is a common disease in India, tuberculosis of right middle lobe is infrequent. Tuberculosis of the right middle lobe leading to chronic collapse is a cause of Right Middle Lobe syndrome. METHODS The patients attended Pulmonary Medicine Outdoor at Era’s Lucknow Medical College, Lucknow from April 2015 to March 2016. The purpose of this study is to describe the clinicoradiological features of patients of middle lobe syndrome due to tuberculosis. All patients presented with cough with or without expectoration, fever, chest pain, haemoptysis and constitutional symptoms like loss of appetite and weight. Chest X-ray PA view revealed ill-defined opacity abutting the right cardiac border. HRCT thorax was done in each case. The diagnosis of tuberculous aetiology was based on (1 History of chronic cough and fever, not responding to antibiotic therapy and constitutional symptoms, (2 A positive tuberculin test using 2 TU of PPD RT 23 and (3 Detection of acid fast bacilli by direct smear or Mycobacterium tuberculosis by polymerase chain reaction in bronchoalveolar lavage. RESULTS Out of 10 patients, 4 (40% were males and 6 (60% were females. The mean ages of the males were 55.8 years and females were 60.8 years and overall mean age was 59 years. Most of the patients were females and belonged to the middle age and old age group. ATT was started in all the patients. CONCLUSIONS Right middle lobe syndrome predominantly affects the older population and the female gender. Although tuberculosis is a common disease in India, Middle Lobe Syndrome is a very rare presentation of the disease. Due to non-specific symptoms and usually normal chest X-ray PA view in Right Middle Lobe Syndrome, we should keep a high index of suspicion to diagnose the condition.

Middle Eastern power systems

1992-01-01

Middle Eastern Power systems have evolved independently of each other over many decades. The region covers a wide geographical area of over 4 million square kilometers with an estimated population in 1990 of over 120 million people. This paper discusses the present status and future power system developments in the Middle East with emphasis on the Mashrequ Arab Countries (MAC). MAC consists of Egypt, Iraq, Jordan, Lebanon, Syria, Yemen, and the six Gulf Cooperation Council (GCC) countries, namely, Bahrain, Kuwait, Qatar, Saudi Arabia, Oman, and the United Arab Emirates (UAE). Interconnections within MAC and possible extensions to Turkey, Europe, and Central Africa are discussed. A common characteristic of the MAC power systems is that they are all operated by government or semi-government bodies. The energy resources in the region are varied. Countries such as Iraq, Egypt, and Syria have significant hydro power resources. On the other hand, the GCC countries and Iraq have abundant fossil fuel reserves

A randomized block experimental design was used, with five replications. The characteristics evaluated were plant height, first branch height, position of first fruiting branch, height of first fruiting branch, length between nodes, number of nodes, average number of bolls per plant, average boll weight, area under the disease progress curve (AUDPC related to the Ramularia leaf spot severity, weight of 100 - seed from the plant middle third, fiber percentage, average production per plant, yield and cotton fiber quality. The results were subjected to individual and joint analysis of variance and the genetic divergence was estimated according to multivariate procedures (Mahalanobis' generalized distance and Tocher's optimization method. The dissimilarity matrices were summed to estimate the genetic divergence, considering both growing periods. Genetic variability was found among the genotypes evaluated, in both the main season and off season. The characteristic that most contributed to the genetic divergence in the main season was the production per plant and, in the off season, was the fiber percentage. According to the results of the present work, the crosses between the genotypes BRS - 335 and FMT - 707; FM - 910 and FMT - 707; and IMA - 08 - 12427 and FMT - 707 are recommended.

The Determinants of Transportation Mode Choice in the Middle Eastern Cities: the Kerman Case, Iran

Directory of Open Access Journals (Sweden)

Hamid Soltanzadeh

2014-07-01

Full Text Available Having a precise understanding of the determinants of transportation mode choices and decisions can be under the influence of regional and cultural aspects. This paper outlines such determinants in the Iranian city of Kerman as a representative of the similar Middle Eastern cities located in hot-arid climates and Moslem cultures. The descriptive analysis of the results derived from a short survey that was a part of a larger study conducted in the second half of 2013 indicated that adding to accessibility to public transportation and the convenience of using it can persuade people to shift from car driving to public transit use. The main barriers to bicycling are socio-cultural aspects, while for walking the obstacles are physical and objective. Increasing the quality of pedestrian infrastructure and spaces is a stronger deterrent than personal attitudes against walking. Such findings show slight dissimilarities from the results of some of the western studies that find the built environment more effective. These findings can be a general guide for the Middle Eastern planners to promote walking, biking, and public transport use.

Middle Holocene Organic Carbon and Biomarker Records from the South Yellow Sea: Relationship to the East Asian Monsoon

Science.gov (United States)

Zou, Liang; Hu, Bangqi; Li, Jun; Dou, Yanguang; Xie, Luhua; Dong, Liang

2018-03-01

The East Asian monsoon system influences the sedimentation and transport of organic matter in East Asian marginal seas that is derived from both terrestrial and marine sources. In this study, we determined organic carbon (OC) isotope values, concentrations of marine biomarkers, and levels of OC and total nitrogen (TN) in core YSC-1 from the central South Yellow Sea (SYS). Our objectives were to trace the sources of OC and variations in palaeoproductivity since the middle Holocene, and their relationships with the East Asian monsoon system. The relative contributions of terrestrial versus marine organic matter in core sediments were estimated using a two-end-member mixing model of OC isotopes. Results show that marine organic matter has been the main sediment constituent since the middle Holocene. The variation of terrestrial organic carbon concentration (OCter) is similar to the EASM history. However, the variation of marine organic carbon concentration (OCmar) is opposite to that of the EASM curve, suggesting OCmar is distinctly influenced by terrestrial material input. Inputs of terrestrial nutrients into the SYS occur in the form of fluvial and aeolian dust, while concentrations of nutrients in surface water are derived mainly from bottom water via the Yellow Sea circulation system, which is controlled by the East Asian winter monsoon (EAWM). Variations in palaeoproductivity represented by marine organic matter and biomarker records are, in general, consistent with the recent EAWM intensity studies, thus, compared with EASM, EAWM may play the main role to control the marine productivity variations in the SYS.

Single-grain OSL dating of Early Middle Palaeolithic deposits at Cuesta de la Bajada, Ebro Basin, Spain

Science.gov (United States)

Arnold, Lee; Demuro, Martina; Santonja, Manuel; Perez-Gonzalez, Alfredo; Pares, Josep

2013-04-01

The open-air site of Cuesta de la Bajada comprises a 2-2.5 m-thick sequence of fluvial-lacustrine sediments inset into the +50-60 m terrace deposits preserved along the south-eastern margins of the Alfambra river valley, Teruel, Spain. The main archaeological horizons lie ~20 m above the present-day river level and consists of an upward-fining sequence of massive fluvial silts and fine sands with dispersed gravels, detritic marls and shales that collectively overlie a series of planar bedded fluvial gravels. These units have yielded ~3000 lithic artefacts displaying reduction techniques characteristic of an early Middle Palaeolithic techno-complex, as well as a multitude of faunal remains indicative of a late Middle Pleistocene origin. The paucity of open-air Palaeolithic sites in the interior eastern sector of the Iberian Peninsula, and the relatively low number of documented early Middle Palaeolithic archives in this region, means that Cuesta de la Bajada is of key importance for understanding the coexistence/transition of Iberian Acheulean and Mousterian techno-complexes during the Middle Pleistocene period. Establishing reliable absolute chronologies at Cuesta de la Bajada remains essential for understanding the regional significance of this site. In an attempt to redress the existing chronological uncertainty we are undertaking an interdisciplinary dating study of the Middle Palaeolithic deposits using OSL dating, ESR/U-series dating of teeth and ESR dating of sedimentary quartz. Here we present results obtained using quartz single-grain OSL dating of 4 samples collected from a 7 m vertical profile bracketing the archaeological horizons. 2 samples were collected from the archaeology-bearing silt and fine sand horizons, while the remaining samples were obtained from well-bedded fine-sands and silts 3.5 m above and 3 m below the main excavation. The measured quartz grains are characterised by relatively bright OSL signals and typically display dose

A number of risk factors leading to malnutrition were investigated among 400 mothers of malnourished children in the middle belt of Nigeria. Poverty, family instability, poor environmental sanitation, faulty weaning practices, illiteracy, ignorance, large family size and preventable infections are the main factors responsible for malnutrition. The strategies for intervention are in the area of health education emphasizing the importance of breastfeeding, family stability, responsible parenthood and small family sizes through culturally acceptable family planning methods. There is need to improve weaning methods through nutrition education, growth monitoring and food demonstration with community participation. Political will is needed to improve literacy status, farming methods and general living conditions.

Full Text Available The present paper focuses on the Middle English preposition twēn(e ‘between, among, in between’. The aim of the study is to review the acknowledged etymology of twēn(e as well as to provide its semantics, dialect distribution, complete textual distribution (record of texts employing twēn(e, and absolute token frequency. Moreover, all texts including the preposition twēn(e are subject to an analysis of the whole variety of prepositions meaning ‘between’ and their token frequency in order to establish the proportions of the use of twēn(e and other discussed prepositions, especially the better established preposition betwēn(e in texts employing twēn(e. The study is based on such extensive electronic databases as the Middle English Dictionary online, the Oxford English Dictionary online and the Corpus of Middle English Prose and Verse as well as on a number of complete Middle English texts. The study of the corpus demonstrates the presence of twēn(e and other prepositions meaning ‘between’ also in texts not listed by the Middle English Dictionary online or the Oxford English Dictionary online under appropriate entries, and thus helps to provide a more complete record of texts and authors utilizing twēn(e and the extent of use of twēn(e as compared to other prepositions meaning ‘between’. Moreover, the study demonstrates that also the other discussed prepositions are often not recorded in particular texts by the MED online or the OED online. In more general terms, the paper points out the need for the use of complete texts for the study of historical prepositions.

Middle School students and their teachers are among the many populations in the U.S. with misconceptions regarding the science or even reality of climate change. Teaching climate change science in schools is of paramount importance since all school-age children will eventually assume responsibility for the management and policy-making decisions of our planet. The recently published Framework for K-12 Science Education (National Research Council, 2012) emphasizes the importance of students understanding global climate change and its impacts on society. A preliminary assessment of over a thousand urban middles school students found the following from pretests prior to a climate literacy curriculum: - Do not understand that climate occurs on a time scale of decades (most think it is weeks or months) -Do not know the main atmospheric contributors to global warming -Do not understand the role of greenhouse gases as major contributors to increasing Earth's surface temperature -Do not understand the role of water vapor to trap heat and add to the greenhouse effect -Cannot identify some of the human activities that increase the amount of CO2 -Cannot identify sources of carbon emissions produced by US citizens -Cannot describe human activities that are causing the long-term increase of carbon -dioxide levels over the last 100 years -Cannot describe carbon reduction strategies that are feasible for lowering the levels of carbon dioxide in the atmosphere To address the lack of a well-designed middle school science climate change curriculum that can be used to help teachers promote the teaching and learning of important climate change concepts, we developed a 20-day Environmental Literacy and Inquiry (ELI): Climate Change curriculum in partnership with a local school district. Comprehension increased significantly from pre- to post-test after enactment of the ELI curriculum in the classrooms. This work is part of an ongoing systemic curriculum reform initiative to promote (1

A middle Pleistocene through middle Miocene moraine sequence in the central Transantarctic Mountains, Antarctica

Balter, A.; Bromley, G. R.; Balco, G.; Thomas, H.; Jackson, M. S.

2017-12-01

Ice-free areas at high elevation in the central Transantarctic Mountains preserve extensive moraine sequences and drift deposits that comprise a geologic record of former East Antarctic Ice Sheet thickness and extent. We are applying cosmogenic-nuclide exposure dating to determine the ages of these moraine sequences at Roberts Massif and Otway Massif, at the heads of the Shackleton and Beardmore Glaciers, respectively. Moraines at these sites are for the most part openwork boulder belts characteristic of deposition by cold-based ice, which is consistent with present climate and glaciological conditions. To develop our chronology, we collected samples from 30 distinct ice-marginal landforms and have so far measured >100 3He, 10Be, and 21Ne exposure ages. Apparent exposure ages range from 1-14 Ma, which shows that these landforms record glacial events between the middle Pleistocene and middle Miocene. These data show that the thickness of the East Antarctic Ice Sheet in this region was similar to or thicker than present for long periods between the middle Miocene and today. The time range represented by these moraine sequences indicates that they may also provide direct geologic evidence for East Antarctic Ice Sheet behavior during past periods of warmer-than-present climate, specifically the Miocene and Pliocene. As the East Antarctic Ice Sheet is the largest ice sheet on earth, understanding its sensitivity to warm-climate conditions is critical for projections of ice sheet behavior and sea-level rise in future warm climates.

Williford, Anne; Boulton, Aaron J; Jenson, Jeffrey M

2014-01-01

We examined the effects of depressive symptoms, antisocial attitudes, and perspective-taking empathy on patterns of bullying and victimization during the transition from late elementary (4th grade to 5th grade) to middle school (6th grade) among 1,077 students who participated in the Youth Matters (YM) bullying prevention trial. Latent transition analysis was used to establish classes of bullying, victimization, bully-victimization, and uninvolvement. The intervention had a positive impact on children as they moved from elementary to middle school. More students in the YM group transitioned from the involved statuses to the uninvolved status than students in the control group during the move to middle school. Elementary school bullies with higher levels of depressive symptoms were less likely than other students to move to an uninvolved status in the first year of middle school. Students who held greater antisocial attitudes were more likely to be a member of the bully-victim status than the uninvolved status during the move to middle school. Perspective-taking empathy, however, was not a significant predictor of status change during the transition to middle school. Implications for school-based prevention programs during the move to middle school are noted. © 2013 Wiley Periodicals, Inc.

After approval from the appropriate school district for a sleep education program, a baseline survey was taken of elementary and middle school students, using the Children’s Sleep Habit Questionnaire-Sleep Self-Report Form, which assessed the domains of bedtime resistance, sleep onset delay, sleep anxiety, sleep duration, night awakening, and daytime sleepiness. Results. The survey was completed by 499 elementary and 1008 middle school children. Trouble sleeping was reported by 43% in elementary school, compared with 29% of middle school children. Fifty percent of middle school children did not like sleeping, compared with 26% in elementary school. Bedtime resistance, sleep onset delay, and nighttime awakening were more common among elementary school students. Daytime sleepiness was more common among the middle school children when compared to elementary school children. Conclusions. Sleep abnormalities are present in elementary school children with changes in sleep habits into middle school.

Chin, Eun Young; Kim, Hyun Kyung

2016-04-01

This study was performed to identify the meaning of life experience following suicide attempt among middle-aged men. A qualitative research design was adopted using van Manen's hermeneutic phenomenological approach. The participants were six middle-aged men who had attempted suicide at least one time. Data were collected in 2013 through in-depth interviews. Individual interviews were recorded; and literary, art works and phenomenological literature were searched to identify the meaning of the experience. The five essential themes of the life experience of middle-aged men who attempted suicide were 'Bitter reality confronted again', 'Anger buried deep inside', 'Broken family, inescapable fetters', 'Blocked relationships, closed world' and 'A step towards a new life'. The meaning of lived experience found in this study provides deep insight into the experience following suicide attempt in middle-aged men and crucial information to give directions to appropriate support and nursing interventions.

The prospects for limiting emissions from road transport: a case study for the Middle Odra and Poland

Science.gov (United States)

Dzikuć, Maciej; Dzikuć, Maria

2018-02-01

The article presents selected aspects related to emissions that arise during road transport. These impurities are an important component of low emission, which is generated at a height of up to 40 m from the ground level. Low emission in the Middle Odra Region and throughout Poland is a serious problem. Low emission has a significant share in total emissions in Poland, where the air is one of the worst in the EU. The problem of low emission concerns not only highly urbanized areas, but also places where the industry is less developed and the number of inhabitants falling on average per square kilometre is less than in the rest of Poland. An example of such an area is the Middle Odra, which additionally features the highest forest cover in the country (more than 50%). The paper highlights the main causes of road transport emissions and points out the need to take action that can significantly help reduce this phenomenon.

APOE-ε4 Allele Altered the Rest-Stimulus Interactions in Healthy Middle-Aged Adults.

Directory of Open Access Journals (Sweden)

Feng-Xian Yan

Full Text Available The apolipoprotein E-ε4 allele is a well-known genetic risk factor for late-onset Alzheimer's disease, which also impacts the cognitive functions and brain network connectivity in healthy middle-aged adults without dementia. Previous studies mainly focused on the effects of apolipoprotein E-ε4 allele on single index using task or resting-state fMRI. However, how these evoked and spontaneous BOLD indices interact with each other remains largely unknown. Therefore, we evaluated the 'rest-stimulus interaction' between working-memory activation and resting-state connectivity in middle-aged apolipoprotein E-ε4 carriers (n=9 and non-carriers (n=8. Four n-back task scans (n = 0, 1, 2, 3 and one resting-state scan were acquired at a 3T clinical MRI scanner. The working-memory beta maps of low-, moderate-, and high-memory loads and resting-state connectivity maps of default mode, executive control, and hippocampal networks were derived and compared between groups. Apolipoprotein E-ε4 carriers presented declined working-memory activation in the high-memory load across whole brain regions and reduced hippocampal connectivity compared with non-carriers. In addition, disrupted rest-stimulus interactions were found in the right anterior insula and bilateral parahippocampal regions for middle-aged adults with apolipoprotein E-ε4 allele. The rest-stimulus interaction improved the detectability of network integrity changes in apolipoprotein E-ε4 carriers, demonstrating the disrupted intrinsic connectivity within the executive-functional regions and the modulated memory-encoding capability within hippocampus-related regions.

Automated external defibrillators (AEDs) have been used in the school setting to successfully resuscitate students, staff, and visitors. All public high schools in North Carolina have an AED. However, the number of North Carolina public middle schools with an AED is unknown. The purpose of this study was to determine the presence of AEDs at public middle schools in North Carolina and to estimate the cost associated with providing an AED to all public middle schools currently without one. All 547 middle schools in North Carolina's 117 public school systems were surveyed in 2009 via e-mail, fax, and, when necessary, telephone about whether an AED was present on site. For middle schools without AEDs, we estimated the cost of purchase and for 1 year of maintenance. A total 66.6% of public middle schools responded to 1 of 3 survey mailings. The remaining schools were contacted by telephone, so that 100% were included in data collection. At the time of the survey, at least 1 AED was present in 334 schools (61.1%). Of the 213 schools without AEDs, 57 (26.8%) were in school systems in which some middle schools had AEDs, and 156 (73.2%) were in systems in which no middle school had an AED. On the basis of a start-up cost of $1,200 per AED, the cost of providing an AED to each school without one is approximately $255,600. These data are based on self-report, and we could not verify whether AEDs were functional. Cost estimates do not include charges for ongoing maintenance and staff training. Two hundred and thirteen North Carolina public middle schools (38.9%) do not have an AED on site.

Spotlight on middle childhood: Rejuvenating the 'forgotten years'.

Science.gov (United States)

Mah, V Kandice; Ford-Jones, E Lee

2012-02-01

Middle childhood, from six to 12 years of age, is often known as the 'forgotten years' of development because most research is focused on early childhood development or adolescent growth. However, middle childhood is rich in potential for cognitive, social, emotional and physical advancements. During this period, the brain is actively undergoing synaptic pruning and, as such, is constantly becoming more refined, a process that is heavily dependent on a child's environment. This discovery opens the door to optimizing the experiences a child needs to provide themselves with a strong foundation for adulthood. The present article reviews the neurological changes that occur in middle childhood, their impact on overall development and how to implement this knowledge to augment a child's capabilities.

2015-06-01

Full Text Available One of the main tasks of universities of Central and Eastern Europe is that of forming loyal and reliable citizens ready to fill in the ranks of public service. Educational credentials make for social elevation into the ranks of this peculiarly state-dependent middle class. Law students make the relative majority of those engaged in higher learning in the region all through the first half of the 20th century. Where and when there is an acute need for a new middle class under a new state sovereignty, it is law studies that are notoriously perceived as meant to producing the bulk of it. The University of Cluj in the inter-war period is a case in point. The paper shall put forward a selection of data (from an ample statistical survey of elite formation via upper-level education in Central Europe on this segment of the student population in the 1930s, setting it against a dramatically changed background (the general one and the local one, as traced in secondary sources: how do Romanians cope with the task of producing this new middle class on old grounds, and what are the unwanted side-effects of such state-related social emancipation mechanisms? And how non-Romanians behave in the new situation?

Innervation of the human middle meningeal artery

1998-01-01

The majority of nerve fibers in the middle meningeal artery and branching arterioles are sympathetic, storing norepinephrine and neuropeptide Y (NPY). A sparse supply of fibers contain acetylcholinesterase activity and immunoreactivity toward vasoactive intestinal peptide (VIP), peptidine histidine...... methionine (PHM), and calcitonin gene-related peptide (CGRP). Only few substance P and neuropeptide K immunoreactive fibers are noted. Electronmicroscopy shows axons and terminals at the adventitial medial border of the human middle meningeal artery, with a fairly large distance to the smooth muscle cells...

Larval ecomorphology of 13 Libellulidae (Anisoptera, Odonata of the Middle Rio Doce Valley, Minas Gerais, Brazil

HC. Giacomini

Full Text Available In the lakes of the Middle Rio Doce, Minas Gerais (MG, two groups of larval Libellulidae are distinguished by preferences of habitat use: one uses mainly aquatic macrophytes and the other uses the bottom substrate. The goal of this work was to verify if there is a morphological distinction between the two groups of species. Thirteen body measures were taken from the larvae and analyzed. No difference was found between the two groups of species regarding the body size, but shape differences were observed for two morphological variables. The species that use mainly macrophytes tend to have larger relative measures of the labium and smaller measures of the abdomen width. Advantages in resource obtainment and in vulnerability to predation are probably the explanations for the morphological divergence among these larval groups.

Total annoyance from an industrial noise source with a main spectral component combined with a background noise.

Science.gov (United States)

Alayrac, M; Marquis-Favre, C; Viollon, S

2011-07-01

When living close to an industrial plant, people are exposed to a combination of industrial noise sources and a background noise composed of all the other noise sources in the environment. As a first step, noise annoyance indicators in laboratory conditions are proposed for a single exposure to an industrial noise source. The second step detailed in this paper involves determining total annoyance indicators in laboratory conditions for ambient noises composed of an industrial noise source and a background noise. Two types of steady and permanent industrial noise sources are studied: low frequency noises with a main spectral component at 100 Hz, and noises with a main spectral component in middle frequencies. Five background noises are assessed so as to take into account different sound environments which can usually be heard by people living around an industrial plant. One main conclusion of this study is that two different analyses are necessary to determine total annoyance indicators for this type of ambient noise, depending on the industrial noise source composing it. Therefore, two total annoyance indicators adapted to the ambient noises studied are proposed. © 2011 Acoustical Society of America

Diagnostic agreement on individual basis between the third middle phalanx maturation (MPM) method and the cervical vertebral maturation (CVM) method has conjecturally been based mainly on overall correlation analyses. Herein, the true agreement between methods according to stage and sex has been evaluated through a comprehensive diagnostic performance analysis. Four hundred and fifty-one Caucasian subjects were included in the study, 231 females and 220 males (mean age, 12.2 ± 2.5 years; range, 7.0-17.9 years). The X-rays of the middle phalanx of the third finger and the lateral cephalograms were examined for staging by blinded operators, blinded for MPM stages and subjects' age. The MPM and CVM methods based on six stages, two pre-pubertal (1 and 2), two pubertal (3 and 4), and two post-pubertal (5 and 6), were considered. Specifically, for each MPM stage, the diagnostic performance in the identification of the corresponding CVM stage was described by Bayesian statistics. For both sexes, overall agreement was 77.6%. Most of the disagreement was due to 1 stage apart. Slight disagreement was seen for the stages 5 and 6, where the third middle phalanx shows an earlier maturation. The two maturational methods show an overall satisfactorily diagnostic agreement. However, at post-pubertal stages, the middle phalanx of the third finger appears to mature earlier than the cervical vertebrae. Post-pubertal growth phase should thus be based on the presence of stage 6 in MPM. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Middle Class and Democracy in Latin America

Directory of Open Access Journals (Sweden)

Jaime Fierro

2015-06-01

Full Text Available The consolidation of the middle class has been interpreted by modernization and postmodernization theories as a key factor for the functioning and stability of the democratic system. However, in Latin America the middle class has tended to be associated with two contradictory positions. On the one hand, it is emphasized that it plays a stabilizing and democratic role while, on the other hand, it is linked to supporting military coups. With the purpose of elucidate such a dilemma, the relationship that can be established between the socioeconomic status and the degree of support for democracy will be examined. In order to do this, an empirical analysis from Latinbarometer surveys databases will be conducted, covering seventeen countries in the region for the period from 1996 to 2011. It will be concluded that the middle class in Latin America does not have particularly more favorable attitudes toward democracy than other social segments.

An Accelerator control middle layer using Matlab

CERN Document Server

Portmann, G J; Terebilo, Andrei

2005-01-01

Matlab is a matrix manipulation language originally developed to be a convenient language for using the LINPACK and EISPACK libraries. What makes Matlab so appealing for accelerator physics is the combination of a matrix oriented programming language, an active workspace for system variables, powerful graphics capability, built-in math libraries, and platform independence. A number of software toolboxes for accelerators have been written in Matlab – the Accelerator Toolbox (AT) for machine simulations, LOCO for accelerator calibration, Matlab Channel Access Toolbox (MCA) for EPICS connections, and the Middle Layer. This paper will describe the MiddleLayer software toolbox that resides between the high-level control applications and the low-level accelerator control system. This software was a collaborative effort between ALS and Spear but was written to easily port. Five accelerators presently use this software – Spear, ALS, CLS, and the X-ray and VUV rings at Brookhaven. The Middle Layer fu...

A Primer of Middle Eastern Leadership Culture

Directory of Open Access Journals (Sweden)

Sheldon Greaves

2012-01-01

Full Text Available It is natural for someone looking in on a foreign culture from the outside to interpret what they see and frame their reactions based on their own background and assumptions. With cultures as a different as those of the Middle East and the West, the potential for blunders increases dramatically, made worse by the high political, diplomatic, military, and commercial stakes involved. Leadership culture in this region has been shaped over centuries through a variety of factors, such as reputation, family, and religion, which continue to influence decision making. The present study posits that an understanding of these factors and how they work is crucial for intelligence analysts, policy and decision makers, strategists, and scholars who must find their way through a very unfamiliar cultural landscape in the Middle East. It is hoped that this discussion will in some way assist in the creation of more effective interaction, policies, and analysis associated with the Middle East.

Consistent response of Indian summer monsoon to Middle East dust in observations and simulations

2015-06-11

The response of the Indian summer monsoon (ISM) circulation and precipitation to Middle East dust aerosols on sub-seasonal timescales is studied using observations and the Weather Research and Forecasting model coupled with online chemistry (WRF-Chem). Satellite data show that the ISM rainfall in coastal southwest India, central and northern India, and Pakistan is closely associated with the Middle East dust aerosols. The physical mechanism behind this dust–ISM rainfall connection is examined through ensemble simulations with and without dust emissions. Each ensemble includes 16 members with various physical and chemical schemes to consider the model uncertainties in parameterizing short-wave radiation, the planetary boundary layer, and aerosol chemical mixing rules. Experiments show that dust aerosols increase rainfall by about 0.44mmday1 ( 10% of the climatology) in coastal southwest India, central and northern India, and north Pakistan, a pattern consistent with the observed relationship. The ensemble mean rainfall response over India shows a much stronger spatial correlation with the observed rainfall response than any other ensemble members. The largest modeling uncertainties are from the boundary layer schemes, followed by short-wave radiation schemes. In WRF-Chem, the dust aerosol optical depth (AOD) over the Middle East shows the strongest correlation with the ISM rainfall response when dust AOD leads rainfall response by about 11 days. Further analyses show that increased ISM rainfall is related to enhanced southwesterly monsoon flow and moisture transport from the Arabian Sea to the Indian subcontinent, which are associated with the development of an anomalous low-pressure system over the Arabian Sea, the southern Arabian Peninsula, and the Iranian Plateau due to dust-induced heating in the troposphere. The dust-induced heating in the mid-upper troposphere is mainly located in the Iranian Plateau rather than the Tibetan Plateau. This study demonstrates

Hussein, A; Abousetta, A

2014-07-01

To explore the role of the nine-step inflation/deflation tympanometric test and resting middle-ear pressure range as predictors of barotrauma in aircrew members. A prospective, non-randomised study was conducted on 100 aircrew members. Resting middle-ear pressure was measured and the nine-step inflation/deflation test performed on all subjects before flights. Subjects were allocated to two groups according to resting middle-ear pressure range (group A, within the range of +26 to +100 and -26 to -100 mmH2O; group B, -25 to +25 mmH2O). All aircrew members were assessed after flights regarding the presence and the grade of barotrauma. In both groups, the sensitivity and specificity values of the entire post-inflation/deflation test were close to those of the post-deflation part of the test. The post-deflation test had a higher negative predictive value than the post-inflation test. Ears with resting middle-ear pressure lower than -55 mmH2O experienced barotrauma, regardless of good or poor post-inflation or post-deflation test results. In an aircrew member, a resting middle-ear pressure within the range of -55 and +50 mmH2O, together with good post-deflation test results, are considered reliable predictors for fitness to fly.

Cancer incidence in Middle Eastern countries, most categorized as low- and middle-income, is predicted to double in the next 10 years, greater than in any other part of the world. While progress has been made in cancer diagnosis/treatment, much remains to be done to improve palliative care for the majority of patients with cancer who present with advanced disease. To determine knowledge, beliefs, barriers, and resources regarding palliative care services in Middle Eastern countries and use findings to inform future educational and training activities. Descriptive survey. Fifteen Middle Eastern countries; convenience sample of 776 nurses (44.3%), physicians (38.3%) and psychosocial, academic, and other health care professionals (17.4%) employed in varied settings. Palliative care needs assessment. Improved pain management services are key facilitators. Top barriers include lack of designated palliative care beds/services, community awareness, staff training, access to hospice services, and personnel/time. The nonexistence of functioning home-based and hospice services leaves families/providers unable to honor patient wishes. Respondents were least satisfied with discussions around advance directives and wish to learn more about palliative care focusing on communication techniques. Populations requiring special consideration comprise: patients with ethnic diversity, language barriers, and low literacy; pediatric and young adults; and the elderly. The majority of Middle Eastern patients with cancer are treated in outlying regions; the community is pivotal and must be incorporated into future plans for developing palliative care services. Promoting palliative care education and certification for physicians and nurses is crucial; home-based and hospice services must be sustained.

Performance Analysis and Optimization of a Parabolic Trough Solar Power Plant in the Middle East Region

Directory of Open Access Journals (Sweden)

Praveen R. P.

2018-03-01

Full Text Available The Middle East is one among the areas of the world that receive high amounts of direct solar radiation. As such, the region holds a promising potential to leverage clean energy. Owing to rapid urbanization, energy demands in the region are on the rise. Along with the global push to curb undesirable outcomes such as air pollution, emissions of greenhouse gases, and climate change, an urgent need has arisen to explore and exploit the abundant renewable energy sources. This paper presents the design, performance analysis and optimization of a 100 MWe parabolic trough collector Solar Power Plant with thermal energy storage intended for use in the Middle Eastern regions. Two representative sites in the Middle East which offer an annual average direct normal irradiance (DNI of more than 5.5 kWh/m2/day has been chosen for the analysis. The thermodynamic aspect and annual performance of the proposed plant design is also analyzed using the System Advisor Model (SAM version 2017.9.5. Based on the analysis carried out on the initial design, annual power generated from the proposed concentrating solar power (CSP plant design in Abu Dhabi amounts to 333.15 GWh whereas that in Aswan recorded a value of 369.26 GWh, with capacity factors of 38.1% and 42.19% respectively. The mean efficiency of the plants in Abu Dhabi and Aswan are found to be 14.35% and 14.98% respectively. The optimization of the initial plant design is also carried out by varying two main design parameters, namely the solar multiple and full load hours of thermal energy storage (TES. Based on the findings of the study, the proposed 100 MW parabolic trough collector solar power plant with thermal energy storage can contribute to the sustainable energy future of the Middle East with reduced dependency on fossil fuels.

Chronic respiratory diseases such as asthma and allergic rhinitis (AR) are a major public health problem in developing countries including those in the Middle East. However, to date, there is a paucity of information related to physician-diagnosed AR in this region. The Allergies in Middle East Survey was undertaken to help clarify and broaden the understanding of physician-diagnosed AR across Egypt, Iran, Lebanon, Saudi Arabia, and the United Arab Emirates. The survey explores the frequency of physician-diagnosed AR, prevalence and types of associated symptoms, the impact on quality of life (QOL), current treatment practices, and therapy expectations. In total, 7411 households in five countries (Egypt, Lebanon, Saudi Arabia, Iran and the United Arab Emirates) were screened to identify individuals that were ≥4 years old with a physician diagnosis of AR and either symptoms and/or treatment in the past 12 months. A total of 501 respondents from the five countries completed the survey. Standardized questionnaires were used to make comparisons across the regions; however, the data collection procedures were tailored for each country. The sample was probability based to ensure valid statistical inference to the population. Ten percent of the Middle East population surveyed had a physician diagnosis of AR, with 65% of respondents stating that their allergies were intermittent in nature. An otolaryngologist or allergist diagnosed the majority of the individuals surveyed. Runny nose, nasal and throat itching, postnasal drip, and nasal congestion or stuffed up nose were the most common and bothersome symptoms of AR. The majority of survey participants (58% of the overall survey population) with AR reported that the condition had an impact on their daily private and professional life. Seventy-two percent of adults reported that their AR symptoms limited their work/school activities and 35% reported that their AR interfered with and caused them to miss work or school within

Diversity and distribution of rush communities from the phragmito-magno-caricetea class in pamir alai mountains (middle asia: tajikistan)

International Nuclear Information System (INIS)

Nowaki, A.; Nowaki, S.

2014-01-01

The study presents results of geobotanical investigations conducted in rush vegetation from the Phragmito-Magno- Caricetea class in the central Pamir-Alai Mts (Tajikistan, Middle Asia). Studies were carried out mainly within the Syr- Daria, Pyandzh, Zeravshan, Kafirnighan, Khanaka and Surkhandaria river valleys in the years 2008, 2012. The research was focused on the classification of rush plant communities developing within this poorly-investigated area. Habitat conditions were checked for all vegetation plots, including pH reaction, water depth, inclination and altitude. Altogether 231 phytosociological releves using the Braun-Blanquet method were sampled. The analyses classified the vegetation into 28 plant communities, including 26 associations. Eight new plant associations were proposed: Scirpetum hippolytii, Mentho asiaticae-Nasturtietum microphyllae, Juncetum brachytepali, Sparganietum stoloniferi, Eleocharitetum argyrolepis, Eleocharitetum mitracarpae, Caricetum songoricae and Rorippo palustris-Alismatetum graminei. The main discrimination factor for the data set is the floristic structure of the associations. Rush vegetation from the Phragmito- Magno-Caricetea class is spread throughout all river valleys of the research areas in montane and subalpine as well as in alpine zones. The vegetation patches occur mainly along the shores of water bodies and in ditches. Only sporadically have rush communities been noted within rice fields, where communities of the class Oryzetea sativae prevail. The study shows that riverside habitats with rush vegetation can harbour a relatively rich flora. Almost 200 species were found in vegetation plots, including some which are rare and have not been recorded until now in this part of Middle Asia. (author)

Alexander A. Kuznetsov

2015-01-01

Full Text Available The article "The Islamic State phenomenon in the framework of the political changes in the Middle East" is dedicated to the "Islamic State", one of the most powerful and dangerous extremist organizations. Author realizes in this article: research of the genesis and causes of appearance of the movement "Islamic State"; analysis of the sociopolitical and geopolitical situation of the Iraqi Sunni community after the American invasion of 2003; bringing to the light factors of the high scale propagation of the Islamic extremism in Syria and Iraq; research of the military and political potential of the "Islamic State" and factors which could impede its expansion. Author considers "Islamic State" as an emergent phenomenon giving huge impact on the political situation in the Middle East. It provoked repartition of the old frontiers existed since the Sykes-Pico treaty of 1916. To the author's opinion oppression of the Iraqi Sunni community by the government of Nuri al-Maliki was the main cause of the Sunni revolt in Summer of 2014. Sunni tribes of Northern Iraq and former Baath party members were the driving forces of the revolt but then Jihadi extremists hijacked this revolt. To the author's mind elimination of the "Islamic State" is impossible without reconciliation between various religious communities in Syria and Iraq.

World gas prospects: which role for the Middle East?

International Nuclear Information System (INIS)

Chabrelie, M.F.

1999-01-01

Since the early 1970's, the policies of energy diversification that have been implemented in the industrialized countries and in many developing countries have enabled natural gas to regularly increase its role in the world energy balance. Thus, during the past twenty years, natural gas to recorded the highest growth rate among fossil fuels, and its share in the energy market has gradually risen from 18.9 % in 1975 to 23 % in 1997. Today, thanks to favorable economic and environmental factors, natural gas has become the fuel of choice on many markets. Indeed, gas its blessed with a certain number of favorable assets (abundant reserves, flexibility, high-performance uses) which give it a major role in all energy demand forecast scenarios. The most spectacular development will indisputably take place in the power generation sector. Endowed with a considerable gas potential, the Middle East will represent an essential source of supply for many industrialized countries and several gas export projects, either by LNG tanker or by pipelines are currently being contemplated. During the past decade the contribution of natural gas to the energy mix also grew substantially in most Middle Eastern countries. The increase in gas demand should continue at a sustained rate, mainly driven by the power generation sector, petrochemicals and energy consumption by the hydrocarbons industry. These promising prospects for gas demand in most the markets in the region might lead to the development of an intra-regional network. However, although opportunities exist, the region will have to meet many challenges in order to contribute more largely to the world gas balance in the years to come. (author)

Paleoceanographic records in the sedimentary cores from the middle Okinawa Trough

Institute of Scientific and Technical Information of China (English)

无

2003-01-01

Two gravity piston cores (Cores 155 and 180) involved in this study were collected from the middle Okinawa Trough. Stratigraphy of the two cores was divided and classified based on the features of planktonic foraminifera oxygen isotope changes together with depositional sequence, millennium-scale climatic event comparison, carbonate cycles and AMS14C dating. Some paleoclimatic information contained in sediments of these cores was extracted to discuss the paleoclimatic change rules and the short-time scale events presented in interglacial period. Analysis on the variation of oxygen isotope values in stage two shows that the middle part of the Okinawa Trough may have been affected by fresh water from the Yellow River and the Yangtze River during the Last Glacial Maximum (LGM). The oxygen isotope value oscillating ranges of the cores have verified that the marginal sea has an amplifying effect on climate changes. The Δ13c of benthic foraminifera Uvigerina was lighter in the glacial period than that in the interglacial period, which indicates that the Paleo-Kuroshio's main stream moved eastward and its influence area decreased. According to the temperature difference during the "YD" period existing in Core 180 and other data, we can reach the conclusion that the climatic changes in the middle Okinawa Trough area were controlled by global climatic changes, but some regional factors had also considerable influence on the climate changes. Some results in this paper support Fairbanks's point that the "YD" event was a brief stagnation of sea level rising during the global warming up procession. Moreover, the falling of sea level in the glacial period weakened the exchange between the bottom water of the Okinawa Trough and the deep water of the northwestern Pacific Ocean and resulted in low oxygen state of bottom water in this area. These procedures are the reasons for carbonate cycle in the Okinawa Trough area being consistent with the "Atlantic type " carbonate cycle.

To evaluate the value of HRCT imaging in middle ear cholesteatoma, we prospectively analysed the CT images in 28 surgically proven cases with cholesteatomas regarding main site of lesion, ossicular change, facial nerve exposure and fistula formation. The most common main site of lesion was the epitympanum (92.8%). The results of sensitivity, positive predictability, and accuracy by CT imagings were as follows: for ossicular involvement, 94.1%, 88.8%, and 86.2% in malleus, 96.0%, 88.8%, and 85.7% in incus, 81.2%, 81.2%, and 78.5% in stapes; for facial nerve exposure, 66.6%, 57.1%, and 81.2%: for fistula formation, 100%, 75.0%, and 96.4%, respectively. In conclusion, the temoral bone HRCT imaging is an accurate preoperative method in detecting main lesion site, ossicular involvement, fistula formation. Because of the low sensitivity and positive predictability in detecting facial nerve exposure, it is necessary to correlate the HRCT images with the clinical status.

We present the method for determining the velocity model of the Earth's crust and the parameters of earthquakes in the Middle Kura Depression from the data of network telemetry in Azerbaijan. Application of this method allowed us to recalculate the main parameters of the hypocenters of the earthquake, to compute the corrections to the arrival times of P and S waves at the observation station, and to significantly improve the accuracy in determining the coordinates of the earthquakes. The model was constructed using the VELEST program, which calculates one-dimensional minimal velocity models from the travel times of seismic waves.

Sound pressure gain produced by the human middle ear.

Science.gov (United States)

Kurokawa, H; Goode, R L

1995-10-01

The acoustic function of the middle ear is to match sound passing from the low impedance of air to the high impedance of cochlear fluid. Little information is available on the actual middle ear pressure gain in human beings. This article describes experiments on middle ear pressure gain in six fresh human temporal bones. Stapes footplate displacement and phase were measured with a laser Doppler vibrometer before and after removal of the tympanic membrane, malleus, and incus. Acoustic insulation of the round window with clay was performed. Umbo displacement was also measured before tympanic membrane removal to assess baseline tympanic membrane function. The middle ear has its major gain in the lower frequencies, with a peak near 0.9 kHz. The mean gain was 23.0 dB below 1.0 kHz, the resonant frequency of the middle ear; the mean peak gain was 26.6 dB. Above 1.0 kHz, the second pressure gain decreased at a rate of -8.6 dB/octave, with a mean gain of 6.5 dB at 4.0 kHz. Only a small amount of gain was present above 7.0 kHz. Significant individual differences in pressure gain were found between ears that appeared related to variations in tympanic membrane function and not to variations in cochlear impedance.

Interracial relationships in Canada have increased over the years. However, little research has focused on comparing STI/HIV risk and condom use between those in intra- and interracial relationships, specifically among Middle Eastern-Canadians. A web-based survey was administered to Middle Eastern-Canadians. Logistic regression analysis was used to assess factors associated with consistent condom use. Analyses were stratified by partner's race (Middle Eastern or non-Middle Eastern). The analysis sub-sample consisted of 92 participants. Factors associated with consistent condom use varied between the stratified groups. Among those with Middle Eastern partners, attitude towards marriage and the family and control in the relationship were associated with condom use. Among participants with non-Middle Eastern partners, acculturation and HIV knowledge were found to be associated with condom use. Factors associated with condom use varied between Middle Eastern-Canadians in intra- and interracial relationships. These differences illustrate the need for tailored interventions aimed at increasing condom use among this racial group.

Purpose of this study was to determine the era when the creation of the volcanos commenced which were extending from north-east to south west, by using the K-Ar age of volcanic rocks which were continuously distributed from middle Kyushu to San-in district and which were mainly composed of amphibole andesite. By comparing with geological map, relation with the stratigraphic order of layers at Yabakei, Himejima and Aono were considered. It was concluded that, in every place, the vocanic activities commenced much later era than creation of basement rock. It was also recognized that, by studying the relation with Phillipine Plate, deep earthquake was related with the volcanic front of south west Japan arc. (8 figs, 2 tabs, 14 refs)

Transportation properties of amorphous state InSb and its metastable middle phase

International Nuclear Information System (INIS)

Cao Xiaowen

1990-09-01

The variation of the substrate temperature induces the metal-semiconductor transition in the condensation InSb films at low temperatrue. The electron conduction is dominant in the metal-type amorphous InSb and the hole in semiconductor-type one. In the metal-type amorphous InSb the electron-electron is correlated under the field above 0.1T in the temperature region of liquid nitrogen. The structure relaxation leads to not only the increase of the short range order but also the change of electron structure in metal-type amorphous InSb. The first conductance jump originates mainly from the increase of Hall mobility of the carrier, i.e. the increase of the short range order, and the system relaxes from the liquid-like to the lattice-like amorphous state. The three types of the crystallization phase transition for the metal-type amorphous InSb present obviously different transportation behaviours. Both metal-type amorphous state and metastable middle phase of InSb all are one of superconducting system with the lowest carrier concentration (n 0 ∼10 18 cm -3 ). Superconducting T c of the metastable middle phase is related to the state density near Fermi surface, i.e. the higher T c corresponds to the higher state density. The quasi-two-dimensional structure is favourable to superconductivity

The pursuit of longevity - the bringer of peace to the middle East.

Science.gov (United States)

Stambler, Ilia

2014-01-01

Despite the common apprehensions regarding the aging population, this work aims to argue, on both deontological and utilitarian moral grounds, that any increase in general life-expectancy will be beneficial for the Middle East, countering the common fears associated with this increase. A set of ethical arguments concerning increasing longevity is presented, from both the deontological and utilitarian perspective. A wide selection of economic, psychological, demographic and epidemiological literature and databases is analyzed to determine common correlates of extended longevity. On the deontological grounds, the value of extended longevity is derived from the value of life preservation, regardless of its term. On the utilitarian grounds, the value of extended longevity is demonstrated by its correlation with further human values, such as education level and intellectual activity, economic prosperity, equality, solidarity and peacefulness. With the common apprehensions of stagnation and scarcity due to life extension found wanting, the pursuit of longevity by the population can be seen as a cross-cultural and cross-generational good. Though the current study mainly refers to sources and data relevant to the Middle East, a similar pro-longevity argument can be also made for other cultural contexts. In view of its numerous benefits, normatively, the goal of longevity should be set clearly and openly by the society, and actively pursued, or at least discussed, in academia, the political system and broader public.

Carrying out these obligations need to connect result in economic and municipal fields to those in environment protection. After a short presentation of these obligations the paper contains a study of waste management in Lipova, a middle sized town in Arad County, Romania. The study is focused mainly on the waste dump of the town, which is planned to be shut down during the following years. This makes necessary to carry out preparing concerning waste management in the new conditions and also to assure environment protection on the actual emplacement after shutting down the existing dump.

The impact of middle manager affective commitment on perceived improvement program implementation success.

Science.gov (United States)

Fryer, Ashley-Kay; Tucker, Anita L; Singer, Sara J

Recent literature suggests that middle manager affective commitment (emotional attachment, identification, and involvement) to an improvement program may influence implementation success. However, less is known about the interplay between middle manager affective commitment and frontline worker commitment, another important driver of implementation success. We contribute to this research by surveying middle managers who directly manage frontline workers on nursing units. We assess how middle manager affective commitment is related to their perceptions of implementation success and whether their perceptions of frontline worker support mediate this relationship. We also test whether a set of organizational support factors foster middle manager affective commitment. We adapt survey measures of manager affective commitment to our research context of hospitals. We surveyed 67 nurse managers from 19 U.S. hospitals. We use hierarchical linear regression to assess relationships among middle manager affective commitment to their units' falls reduction program and their perceptions of three constructs related to the program: frontline worker support, organizational support, and implementation success. Middle manager affective commitment to their unit's falls reduction program is positively associated with their perception of implementation success. This relationship is mediated by their perception of frontline worker support for the falls program. Moreover, middle managers' affective commitment to their unit's falls program mediates the relationship between perceived organizational support for the program and perceived implementation success. We, through this research, offer an important contribution by providing empirical support of factors that may influence successful implementation of an improvement program: middle manager affective commitment, frontline worker support, and organizational support for an improvement program. Increasing levels of middle manager affective

High resolution computed tomography was performed in 57 cases with various middle ear diseases (chronic otitis media, otitis media with effusion, acute otitis media and atelectasis). Although further improvement in detectability is necessary in order to discriminate each type of the soft tissue lesions, CT is the most useful method currently available in detecting the small structures and soft tissue lesions of the middle ear. In particular, the lesions at the tympanic isthmus and tympanic fold could very clearly be detected only by CT. In acute otitis media, lesions usually started in the attic and spread to the mastoid air cells. In otitis media with effusion, the soft tissue shadow was ovserved in the attic and mastoid air cell. CT is valuable in diagnosis, evaluation of the treatment and prognosis, and analysis of pathophysiology in the middle ear diseases. (author)

The Belief Diversity Scale (BDS) was administered to Australian, Canadian, Egyptian, and South African participants of different religious backgrounds. The BDS is a 33-item, six subscale instrument that is designed to quantitatively measure Middle Eastern extremist ideologies on risk areas that are reported in the literature. Results demonstrated the reliability and validity of the BDS, thus suggesting that the BDS could be used as an objective tool to measure Middle Eastern extremist ideologies. Results also supported the hypothesis of prevalence of Middle Eastern extremist ideologies around different parts of the world.

The Science of Middle Nature

Pataki, D. E.; Pincetl, S.

In the field of biogeochemistry, urbanization is often considered as an "alteration" or "disturbance" to the earth's surface and its natural processes. This view is an outcome of the view of nature inherent in earth system science and ecology, in which nature is defined as separate from humans and society. However, other disciplines are based in alternative views of nature in which humans are more integral components of the landscape. Urban planning, landscape architecture, agriculture, and horticulture, for example, more fully integrate the role of landscape design and management in the functioning of human-dominated ecosystems. We suggest that the field of urban biogeochemistry has been somewhat limited by the predominant, disturbance-based view of the role of nature in cities, and that more deeply evaluating and broadening the concept of nature inherent in studies of urban processes can enhance our understanding of the role of urbanization in the earth system. A particularly useful concept is the "middle nature" proposed by Cosgrove (1993), which serves a purpose of "actively transforming nature into culture." It is this view of urban landscapes as middle nature, or transformation of urban space into human-dominated nature with a purpose, that is lacking from the current scientific discourse about the role of biogeochemistry in urban ecosystem services. A scientific evaluation of middle nature implies studying the performance of urban designs to meet intended cultural and environmental goals, including beauty, social equity, governance, and social capital as well as environmental quality. We describe our work in evaluating the transformed urban landscapes of Los Angeles from multiple perspectives that focus on urban livability, equity, and beauty as well as the physical impacts of plants and soils on the environment. The outcomes of this process do not necessary meet the traditional demands of biophysical ecology such as utilizing native species, maximizing

An Accelerator Control Middle Layer Using MATLAB

Portmann, Gregory J.; Corbett, Jeff; Terebilo, Andrei

2005-01-01

Matlab is an interpretive programming language originally developed for convenient use with the LINPACK and EISPACK libraries. Matlab is appealing for accelerator physics because it is matrix-oriented, provides an active workspace for system variables, powerful graphics capabilities, built-in math libraries, and platform independence. A number of accelerator software toolboxes have been written in Matlab -- the Accelerator Toolbox (AT) for model-based machine simulations, LOCO for on-line model calibration, and Matlab Channel Access (MCA) to connect with EPICS. The function of the MATLAB ''MiddleLayer'' is to provide a scripting language for machine simulations and on-line control, including non-EPICS based control systems. The MiddleLayer has simplified and streamlined development of high-level applications including configuration control, energy ramp, orbit correction, photon beam steering, ID compensation, beam-based alignment, tune correction and response matrix measurement. The database-driven Middle Layer software is largely machine-independent and easy to port. Six accelerators presently use the software package with more scheduled to come on line soon

Matlab is a matrix manipulation language originally developed to be a convenient language for using the LINPACK and EISPACK libraries. What makes Matlab so appealing for accelerator physics is the combination of a matrix oriented programming language, an active workspace for system variables, powerful graphics capability, built-in math libraries, and platform independence. A number of software toolboxes for accelerators have been written in Matlab--the Accelerator Toolbox (AT) for machine simulations, LOCO for accelerator calibration, Matlab Channel Access Toolbox (MCA) for EPICS connections, and the Middle Layer. This paper will describe the ''middle layer'' software toolbox that resides between the high-level control applications and the low-level accelerator control system. This software was a collaborative effort between ALS (LBNL) and SPEAR3 (SSRL) but easily ports to other machines. Five accelerators presently use this software. The high-level Middle Layer functionality includes energy ramp, configuration control (save/restore), global orbit correction, local photon beam steering, insertion device compensation, beam-based alignment, tune correction, response matrix measurement, and script-based programs for machine physics studies

An Exploratory Study of a Robotics Educational Platform on STEM Career Interests in Middle School Students

Science.gov (United States)

Hinton, Tracy Barger

With the large expected growth in STEM-related careers in American industries, there are not enough graduates to fill these positions (United States Department of Labor, 2015). Increased efforts are being made to reform STEM education from early childhood to college level studies, mainly through increased efforts to incorporate new technologies and project-based learning activities (Hegedorn & Purnamasari, 2012). At the middle school level, a robotics educational platform can be a worthwhile activity that provides hands-on learning as students learn basic programming and engineering skills (Grubbs, 2013). Based on the popularity of LEGO toys, LEGO Education developed an engaging and effective way to learn about computer programming and basic engineering concepts (Welch & Huffman, 2011). LEGO MINDSTORMS offers a project-based learning environment that engages students in real-life, problem-solving challenges. The purpose of this qualitative study was to investigate the instructional use of a robotics educational curriculum on middle school students' attitudes toward and interests in STEM and their experiences with LEGO Robotics activities. Participants included 23 seventh grade students who were enrolled in a Career Cluster Technologies I class in a suburban middle school. Data for the study were collected from three focus group interviews, open-ended surveys, classroom observations, and the Career Cruising program. Findings revealed that the robotics activities led to an increased interest and higher self-efficacy in STEM tasks. If students continue to nurture and develop their STEM interests, it is possible that many of them may develop higher confidence and eventually set personal goals related to STEM classes and careers. While other studies have been conducted on similar topics, this qualitative research is unique because it contributed to the gap in research that investigates the impact of an in-class robotics curriculum on middle school students' attitudes

How does the predicted geomagnetic main field variation alter the thermosphere-ionosphere storm-time response?

Science.gov (United States)

Maute, A. I.; Lu, G.; Richmond, A. D.

2017-12-01

Earth's magnetic main field plays an important role in the thermosphere-ionosphere (TI) system, as well as its coupling to Earth's magnetosphere. The ionosphere consists of a weakly ionized plasma strongly influenced by the main field and embedded in the thermosphere. Therefore, ion-neutral coupling and ionospheric electrodynamics can influence the plasma distribution and neutral dynamics. There are strong longitude variations of the TI storm response. At high latitude magnetosphere-ionosphere coupling is organized by the geomagnetic main field, leading in general to stronger northern middle latitude storm time response in the American sector due to the geomagnetic dipole location. In addition, the weak geomagnetic main field in the American sector leads to larger local ExB drift and can alter the plasma densities. During geomagnetic storms the intense energy input into the high latitude region is redistributed globally, leading to thermospheric heating, wind circulation changes and alterations of the ionospheric electrodynamics. The storm time changes are measurable in the plasma density, ion drift, temperature, neutral composition, and other parameters. All these changes depend, to some degree, on the geomagnetic main field which changes on decadal time scales. In this study, we employ a forecast model of the geomagnetic main field based on data assimilation and geodynamo modeling [Aubert et al., 2015]. The main field model predicts that in 50 years the South Atlantic Anomaly is further weakened by 2 mT and drifts westward by approximately 10o. The dipole axis moves northward and westward by 2o and 6o, respectively. Simulating the March 2015 geomagnetic storm with the Thermosphere-Ionosphere Electrodynamics General Circulation Model (TIE-GCM) driven by the Assimilative Mapping of Ionospheric Electrodynamics (AMIE), we evaluate the thermosphere-ionosphere response using the geomagnetic main field of 2015, 2065, and 2115. We compare the TI response for 2015 with

Only a few studies have focused on the association between overall diet, rather than intakes of individual nutrients or foods, and depressive symptoms in Japanese. This cross-sectional study examined associations between a diet quality score and depressive symptoms in 3963 young (age 18 years) and 3833 middle-aged (mean age 47·9 (sd 4·2) years) Japanese women. Dietary information was collected using a diet history questionnaire. A previously developed diet quality score was computed mainly based on the Japanese Food Guide Spinning Top. The prevalence of depressive symptoms was 22·0 % for young women and 16·8 % for middle-aged women, assessed as a Center for Epidemiologic Studies Depression (CES-D) score ≥23 and ≥19, respectively. As expected, the diet quality score was associated positively with intakes of 'grain dishes', 'vegetable dishes', 'fish and meat dishes', 'milk' and 'fruits' and inversely with intakes of energy from 'snacks, confection and beverages' and Na from seasonings. After adjustment for potential confounders, OR for depressive symptoms in the highest v. lowest quintiles of the diet quality score was 0·65 (95 % CI 0·50, 0·84) in young women (P for trend=0·0005). In middle-aged women, the corresponding value was 0·59 (95 % CI 0·45, 0·78) (P for trenddiet quality and CES-D scores were treated as continuous variables also showed inverse associations. In conclusion, this cross-sectional study showed that a higher diet quality score was associated with a lower prevalence of depressive symptoms in young and middle-aged Japanese women. Prospective studies are needed to confirm a public health relevance of this finding.

Global change studies aim to foster a deeper understanding of the causes and consequences of global change on planet Earth. The study of global change presents a rich domain of inquiry, exploration, and discovery at all grade levels. The main objective of this exploratory study was to assess middle school students' perceptions of global change as part of their participation in the NSF GK12 program called GLACIER (Global Change Initiative - Education and Research) during the academic year 2012-13. The middle schools are located in the Metro Boston area. As part of the program, participating students were asked to draw pictures of their perceptions and ideas on global change. The drawings of 150 children, ages 11 to 13, were qualitatively analyzed. The analysis focused on (a) the type of concepts children chose to convey, (b) the specific context of the global change described (polar bears in floating glaciers), (c) students direct representation of anthropocentric impacts (such as pollution or deforestation), and (d) the match between students concepts and the recent IPCC reports. About 20% of the students focused on the iconic imagery of the melting glaciers and impact on animals such as penguins and polar bears, more than 25% focused on natural disasters (such as storms, sea level changes) while 30% focused on urban problems. These concepts are matched with the recent IPCC report. These results are notable and suggest students in middle schools understand the varied dimensions of global change and the role of human activities in bringing about change. Students' perspectives may help in developing a suitable curriculum using existing science standards to discuss this significant topic in middle school classrooms. In addition, students' drawings illustrate their perception of the coupled human and natural systems.

High-altitude wind resources in the Middle East

KAUST Repository

Yip, Chak Man Andrew; Gunturu, Udaya; Stenchikov, Georgiy L.

2017-01-01

In the Middle East, near-surface wind resources are intermittent. However, high-altitude wind resources are abundant, persistent, and readily available and may provide alternative energy resources in this fossil-fuel-dependent region. Using wind field data from the Modern-Era Retrospective Analysis for Research and Applications Version 2 (MERRA-2), this study identifies areas favorable to the deployment of airborne wind energy (AWE) systems in the Middle East and computes the optimal heights at which such systems would best operate. AWE potential is estimated using realistic AWE system specifications and assumptions about deployment scenarios and is compared with the near-surface wind generation potential with respect to diurnal and seasonal variability. The results show the potential utility of AWE in areas in the Middle East where the energy demand is high. In particular, Oman and Saudi Arabia have a high level of the potential power generation with low annual variability.

Congenital malformations of the external and middle ear

With the focus on imaging, this paper gives a summarized view of the present knowledge on fields, which are necessary to know for a profound understanding of congenital malformations of the external and middle ear. Typical and less typical combinations of malformed parts of the ear can be derived from the embryogenesis. Clinical signs and audiometric findings lead to diagnosis in congenital aural atresia. Isolated middle ear malformations can be clinically mixed up especially with otosclerosis and tympanosclerosis. Imaging is needed for exact morphological information. In malformations of the external and middle ear, CT is the imaging modality of choice. Requirements on CT-technique as well as radiological findings including classification and pre-surgical rating are described. Morphological CT-correlates of congenital malformations and their differential diagnoses are enlisted and illustrated. The impact of CT-results on therapy is explained and actual therapeutic concepts are briefly presented

A six-part collisional model of the main asteroid belt

Science.gov (United States)

Cibulková, H.; Brož, M.; Benavidez, P. G.

2014-10-01

In this work, we construct a new model for the collisional evolution of the main asteroid belt. Our goals are to test the scaling law of Benz and Asphaug (Benz, W., Asphaug, E. [1999]. Icarus, 142, 5-20) and ascertain if it can be used for the whole belt. We want to find initial size-frequency distributions (SFDs) for the considered six parts of the belt (inner, middle, “pristine”, outer, Cybele zone, high-inclination region) and to verify if the number of synthetic asteroid families created during the simulation matches the number of observed families as well. We used new observational data from the WISE satellite (Masiero et al., 2011) to construct the observed SFDs. We simulate mutual collisions of asteroids with a modified version of the Boulder code (Morbidelli, A., et al. [2009]. Icarus, 204, 558-573), where the results of hydrodynamic (SPH) simulations of Durda et al. (Durda, D.D., et al. [2007]. Icarus, 498-516) and Benavidez et al. (Benavidez, P.G., et al. [2012]. 219, 57-76) are included. Because material characteristics can significantly affect breakups, we created two models - for monolithic asteroids and for rubble-piles. To explain the observed SFDs in the size range D=1 to 10 km we have to also account for dynamical depletion due to the Yarkovsky effect. The assumption of (purely) rubble-pile asteroids leads to a significantly worse fit to the observed data, so that we can conclude that majority of main-belt asteroids are rather monolithic. Our work may also serve as a motivation for further SPH simulations of disruptions of smaller targets (with a parent body size of the order of 1 km).

Students' mental health is associated to academic performance. In high income countries, higher students' grades are related to lower odds of suicidal behaviors, but studies on other indicators of academic performance are more limited, specially in middle income countries. Data from 28,519 middle and high school students selected with multistage clustered sampling in the Mexican National Survey of Student's Drug Use. Using a self-administered questionnaire, lifetime suicidal attempt and four indicators of academic performance were assessed: age inconsistency with grade level, not being a student in the last year, perceived academic performance and number of failed courses. Multiple logistic regression models were used to control for sociodemographic and school characteristics. The lifetime prevalence of attempted suicide was 3.0% for middle school students and 4.2% for high school students. Among middle school students, statistically adjusted significant associations of suicide attempt with academic performance indicators were: not being a student the year before, worse self-perceived performance and a higher number of failed courses; among high school students, predictors were failed courses and self-perceived academic performance, with ORs of 1.65 and 1.96 for the categories of good and fair/poor respectively, compared to those who reported very good performance. Self-perceived academic performance was the main indicator for suicide in both school levels. Suicide prevention efforts in Mexico's schools should include asking students about the perception they have about their own academic performance.

A comparative study of the effectiveness of "Star Show" vs. "Participatory Oriented Planetarium" lessons in a middle school Starlab setting

Science.gov (United States)

Platco, Nicholas L.., Jr.

2005-06-01

The purpose of this study was to compare the effectiveness of "Star Show" and the "Participatory Oriented Planetarium" (POP) instructional programs in a middle school Starlab setting. The Star Show is a planetarium program that relies heavily on an audiovisual/lecture format to impart information, while the POP method of instruction is an inquiry, activity-based approach to teaching astronomy. All Star Show and POP lessons were conducted in a Starlab planetarium. This study examined the effectiveness of the two methods on the attainment of astronomy knowledge, changes in student attitudes toward astronomy, retention of knowledge, and gender differences. A pilot study (N = 69) was conducted at a middle school near King of Prussia, Pennsylvania. The main study (N = 295) was conducted at a middle school near Reading, Pennsylvania. All students were pretested and posttested in both studies. The testing instruments included a 60-question paper-and-pencil content test and a 22-item Likert-style science attitude test. The content test was judged to be valid and reliable by a panel of science educators. The attitude test is a field-tested attitude survey developed by Michael Zeilik. The topics included in the Star Show and POP lessons were seasons, moon phases, eclipses, stars, and constellations. The Star Show programs used in this study are professionally prepared planetarium programs from Jeff Bowen Productions. Several planetarium educators who have been involved with planetarium training workshops throughout the United States developed the POP lessons used in this study. The Star Show was clearly the more effective method for improving student knowledge in both the pilot and main studies. Both methods were equally effective for improving student attitudes toward astronomy. The POP method was the more effective method of instruction when retention of knowledge was examined four weeks after the treatments ended. Gender did not have any significant effect on this study

To assess whether alcohol, tobacco, and other drug (ATOD) use in elementary school may have serious implications for continued ATOD use in middle school and beyond. Longitudinal analyses were conducted on questionnaire data from 331 middle school students who had previously provided ATOD-use data during elementary school. Non-school personnel administered questionnaires in three participating school districts in three different states. The sample of students was ethnically and geographically diverse, including students from a range of low socioeconomic status backgrounds living in rural, urban or inner-city environments. Middle school alcohol use was almost three times as likely to occur if alcohol use had occurred in elementary school (OR = 2.94, p Elementary school use of tobacco and marijuana also greatly increased the likelihood of middle school use (OR = 5.35, p elementary school, during the middle childhood years.

Holocene depositional history of a large glaciated estuary, Penobscot Bay, Maine

Science.gov (United States)

Knebel, H.J.

1986-01-01

Data from seismic-reflection profiles, sidescan sonar images, and sediment samples reveal the Holocene depositional history of the large (1100 km2) glaciated Penobscot Bay estuary of coastal Maine. Previous work has shown that the late Wisconsinan ice sheet retreated from the three main passages of the bay between 12,700 and 13,500 years ago and was accompanied by a marine transgression during which ice and sea were in contact. Isostatic recovery of the crust caused the bay to emerge during the immediate postglacial period, and relative sea level fell to at least -40 m sometime between 9000 and 11,500 years ago. During lowered sea level, the ancestral Penobscot River flowed across the subaerially exposed head of the bay and debouched into Middle Passage. Organic-matter-rich mud from the river was deposited rapidly in remnant, glacially scoured depressions in the lower reaches of Middle and West Passages behind a shallow (???20 m water depth) bedrock sill across the bay mouth. East Passage was isolated from the rest of the bay system and received only small amounts of locally derived fine-grained sediments. During the Holocene transgression that accompanied the eustatic rise of sea level, the locus of sedimentation shifted to the head of the bay. Here, heterogeneous fluvial deposits filled the ancestral valley of the Penobscot River as base level rose, and the migrating surf zone created a gently dipping erosional unconformity, marked by a thin (energy conditions and the waning influence of the Penobscot River at the head of the bay. In contrast, relatively thick (up to 25 m) silty clays accumulated within a subbottom trough in the western half of the bay head. This deposit apparently developed late in the transgression after sea level had reached -20 m and after the westward transport of fine-grained sediments from the Penobscot River had been established. During and since the late Holocene transgression of sea level, waves and currents have eroded, reworked, and

Automobile driving is a safety-critical real-world example of multitasking. A variety of roadway and in-vehicle distracter tasks create information processing loads that compete for the neural resources needed to drive safely. Drivers with mind and brain aging may be particularly susceptible to distraction due to waning cognitive resources and control over attention. This study examined distracted driving performance in an instrumented vehicle (IV) in 86 elderly (mean=72.5 years, SD=5.0 years) and 51 middle-aged drivers (mean=53.7 years, SD=9.3 year) under a concurrent auditory-verbal processing load created by the Paced Auditory Serial Addition Task (PASAT). Compared to baseline (no-task) driving performance, distraction was associated with reduced steering control in both groups, with middle-aged drivers showing a greater increase in steering variability. The elderly drove slower and showed decreased speed variability during distraction compared to middle-aged drivers. They also tended to "freeze up", spending significantly more time holding the gas pedal steady, another tactic that may mitigate time pressured integration and control of information, thereby freeing mental resources to maintain situation awareness. While 39% of elderly and 43% of middle-aged drivers committed significantly more driving safety errors during distraction, 28% and 18%, respectively, actually improved, compatible with allocation of attention resources to safety critical tasks under a cognitive load.

Numerous studies have focused on the diversity of audiovisual integration between younger and older adults. However, consecutive trends in audiovisual integration throughout life are still unclear. In the present study, to clarify audiovisual integration characteristics in middle-aged adults, we instructed younger and middle-aged adults to conduct an auditory/visual stimuli discrimination experiment. Randomized streams of unimodal auditory (A), unimodal visual (V) or audiovisual stimuli were presented on the left or right hemispace of the central fixation point, and subjects were instructed to respond to the target stimuli rapidly and accurately. Our results demonstrated that the responses of middle-aged adults to all unimodal and bimodal stimuli were significantly slower than those of younger adults (p Audiovisual integration was markedly delayed (onset time 360 ms) and weaker (peak 3.97%) in middle-aged adults than in younger adults (onset time 260 ms, peak 11.86%). The results suggested that audiovisual integration was attenuated in middle-aged adults and further confirmed age-related decline in information processing.

Panasenko, N. N.; Sinelschikov, A. V.

2017-11-01

One of the main stages in the analysis of complex 3D structures and engineering constructions made of thin-walled open bars using FEM is a stiffness matrix developing. Taking into account middle surface shear deformation caused by the work of tangential stresses in the formula to calculate a potential energy of thin-walled open bars, the authors obtain an important correction at calculation of the bar deformation and fundamental frequencies. The results of the analysis of the free end buckling of a cantilever H-bar under plane bending differ from exact solution by 0.53%. In the course of comparison of the obtained results with the cantilever bar buckling regardless the middle surface shear deformation, an increase made 16.6%. The stiffness matrix of a thin-walled open bar developed in the present work can be integrated into any software suite using FEM for the analysis of complex 3-D structures and engineering constructions with n-freedoms.

On the Formation of Verb Compounds in Early Middle Japanese

Directory of Open Access Journals (Sweden)

Wenchao LI

2013-12-01

Full Text Available This paper is dedicated to the formation of verb compounds in Early Middle Japanese, a stage of the Japanese language used in the Heian Period (794–1185. The findings reveal that current verb compounds have come a long way from Old Japanese. Multiple verbs in Old Japanese are assigned to an associate type, rather than a compounding type of relation. Thus, the serial constituents receive equal syntactic weight, giving rise to the extensive use of the coordinate type and succession type of multi-verbs. In Early Middle Japanese, the combinations of the two constituents seem much tighter, giving rise the frequent use of the modifier-predicate V-V. The conclusion emerging from this study is that it was not until Early Middle Japanese that verb compounds in the strict sense appeared. Moreover, two types of verb weakening are observed in Early Middle Japanese: (a transformation of the first verb into a prefix, (b grammaticalization of the second verb into a directional/resultative complement.

The post-war Middle East

Tempest, P.

1992-01-01

The Middle East remains today the global energy fulcrum. One year after the Persian Gulf war, the region is in greater turmoil and political uncertainty than it has known in modern times. The Iraqi invasion of Kuwait and subsequent external military intervention forced neighboring states to question the need for a foreign military presence in the future. The rift between the secular revolutionary states in the region led by Iraq, Libya, Yemen, Algeria, and Syria and the traditional monarchy of Saudi Arabia and the emirates of the gulf has widened. Egypt provides, at present, an uncomfortable bridge. The balance of political forces may be shifting. This paper attempts to answer the following questions: Where will we see the new leadership in the Middle East? Will it again play a role through the Organization of Petroleum Exporting Countries and determination of the oil price in shaping the structure of global energy supply and demand?

Pulkkinen, Lea; Kokko, Katja; Rantanen, Johanna

2012-09-01

Continuity in individual differences from socioemotional behavior in middle childhood to personality characteristics in middle adulthood was examined on the assumption that they share certain temperament-related elements. Socioemotional characteristics were measured using teacher ratings at ages 8 (N = 369; 53% males) and 14 (95% of the initial sample). Personality was assessed at age 42 (63% of the initial sample; 50% males) using a shortened version of the NEO Personality Inventory (NEO-PI); the Karolinska Scales of Personality (KSP); and the Adult Temperament Questionnaire (ATQ). Three models were tested using structural equation modeling. The results confirmed paths (a) from behavioral activity to adult Extraversion and Openness (NEO-PI), sociability (KSP), and surgency (ATQ); (b) from well-controlled behavior to adult conformity (KSP) and Conscientiousness (NEO-PI); and (c) from negative emotionality to adult aggression (KSP). The paths were significant only for one gender, and more frequently for males than for females. The significant male paths from behavioral activity to all indicators of adult activity and from well-controlled behavior to adult conformity started at age 8, whereas significant female paths from behavioral activity to adult sociability and from well-controlled behavior to adult Conscientiousness started at age 14.

The reciprocal constitutive features of a Middle Eastern partnership: The Russian–Syrian bilateral relations

Directory of Open Access Journals (Sweden)

Theodor Tudoroiu

2015-07-01

Full Text Available Using the concept of reciprocal socialization, this article argues that the Damascus–Moscow partnership has been since 1970 a reciprocal constitutive relation that has influenced considerably the actions, interests, and identities of the two partners. During the last two decades of the Cold War it represented an almost ideal-type example of a relationship between a super-power and its regional ally that, through its complex consequences, shaped significantly the two partners themselves, the Middle Eastern political and security environment, and the international system as a whole. Post-2003 developments and especially the present Syrian crisis also have influenced considerably the two states' identity-building processes. After the US invasion of Iraq, the patterns of renewed bilateral cooperation have mirrored, at least in part, the Cold War ones. The Arab Spring enforced this trend. Yet, today the International Relations identity of Russia is quite different from the Soviet era one. The main consequence is that Moscow's new identity prevents it from supporting the regime in Damascus at any cost. If military operations take a turn threatening seriously the survival of that regime, it is likely that the Kremlin will not escalate its pro-al-Asad involvement, thus accepting the possible fall of its Middle Eastern ally.

Coping With Verbal and Social Bullying in Middle School

Christopher Donoghue

2014-11-01

Full Text Available Becoming a victim of verbal and social bullying in middle school can lead to illness, psychological stress, and maladjustment. The coping strategies that students utilize when they are bullied may influence the likelihood and severity of these negative effects. In this study, we examined the predictions made by students in two middle schools about the ways that they would cope with becoming a victim of verbal and social bullying. We also analyzed influences for coping strategies and student willingness to seek help with bullying at school. The results show that middle school students generally expect that they will utilize adaptive approach strategies in trying to solve the problem or obtain support from others, but those who had been victimized in the last month were more likely than those not involved in bullying, to predict that they would engage in maladaptive avoidance coping strategies if victimized in the future. Willingness to seek help was found to be enhanced by approach coping strategies, less aggressive attitudes, and lower perceptions of school bullying. Policy implications for efforts to encourage approach coping strategies in middle school students through educational interventions and school counseling are discussed.

To describe the use of a piezosurgery medical device to perform a craniotomy and produce a split calvarial graft for the repair of middle cranial fossa meningoencephaloceles. Retrospective case review. Tertiary referral hospital. Ten consecutive patients undergoing middle cranial fossa approach for the repair of meningoencephaloceles. Therapeutic. Intraoperative and postoperative complications, success rate as defined by the ability to fashion a split calvarial graft that achieves complete closure of the tegmen defect. As a secondary outcome measure, evidence of integration of the split calvarial bone graft with the adjacent skull base was assessed. There were no intraoperative or postoperative complications. An appropriately sized calvarial bone graft was produced, and complete closure of the tegmen defect was achieved in all 10 cases. Computed tomography demonstrated evidence of integration of the bone graft in eight cases between 4 and 9 months after surgery. The piezosurgery medical device provides a safe and effective means by which the middle fossa craniotomy and split calvarial bone graft can be produced to repair defects of the middle fossa tegmen, with integration of the bone graft in the majority of cases.

Steps toward a Middle East free of nuclear weapons

International Nuclear Information System (INIS)

Leonard, J.

1991-01-01

In the aftermath of the Gulf War, all eyes are focused on the dangers of proliferation in the Middle East. President Bush, in his postwar address to Congress, called for immediate action to control the proliferation of weapons of mass destruction and the missiles used to deliver them, warning that it would be tragic if the nations of the Middle East and Persian Gulf were now, in the wake of war, to embark on a new arms race. Secretary of State James Baker has recently returned from a tour of the region, and consultations on proliferation were reportedly high on his agenda. At the same time, the fierce political antagonisms and unbridled military competitions that have long characterized the Middle East leave many skeptical as to what can realistically be done. While all states in the region - including Israel - have publicly supported the idea of establishing a nuclear-weapon-free zone (NWFZ) in the Middle East, doubt over the feasibility of the proposal runs high. Why on earth, it is asked, would Israelis give up the protection of their nuclear monopoly? What assurances from their Arab adversaries or from the US could possibly replace this ultimate deterrent?

Preliminary investigation on the sedimentary facies of the middle silurian uraniferous rock formations in western Qinling Region

International Nuclear Information System (INIS)

Mao Yunian; Min Yongming.

1987-01-01

The Middle Silurian stratabound uranium deposits in Western Qinling were formed due to hydrothermal modification of ground water and reconcentration of uranium from the sedimentary source rocks. The Silurian system consists of the sediments deposited in the marginal sea of the passive continent, to the south of which is the Ruoergai palaeocontinent. The Middle Silurian is divided into three formations. The lower members of each formation are composed of fine-grained clastic rocks with bay-lagoon facies, while the upper members of each formation are uraniferous rock formations consisted of carbonaceous-siliceous-limestone-argillaceous rocks. During the Middle Silurian period there occurred an island chain barrier which is roughly parallel to the palaeocoast and was formed by undersea uplifts. The uraniferous rock formations belong to the assemblage of lagoon-reef-back tidal flat-reef beach facies. Nearshore shallow water environment, abundant terrestrial fine detritus, local reduction facies and zones are three cardinal conditions for the formation of uranium-rich sediments. Uranium deposition mainly took place in the environments of the inner part of reef beach and reef-back tidal flat, which are characterized by having medium to slightly lower energy, the terrestrial fine detritus involved, and local reduction field resulting from the decomposition of organism after their massive death. Furing the process of relative slow deposition, UO 2 2+ in the sea water was formed by means of infiltration, diffusion and alternative absorption of water at the bottom into organic matter and clay

Reconstructing in space and time the closure of the middle and western segments of the Bangong-Nujiang Tethyan Ocean in the Tibetan Plateau

When and how the Bangong-Nujiang Tethyan Ocean closed is a highly controversial subject. In this paper, we present a detailed study and review of the Cretaceous ophiolites, ocean islands, and flysch deposits in the middle and western segments of the Bangong-Nujiang suture zone (BNSZ), and the Cretaceous volcanic rocks, late Mesozoic sediments, and unconformities within the BNSZ and surrounding areas. Our aim was to reconstruct the spatial-temporal patterns of the closing of the middle and western segments of the Bangong-Nujiang Tethyan Ocean. Our conclusion is that the closure of the ocean started during the Late Jurassic and was mainly complete by the end of the Early Cretaceous. The closure of the ocean involved both "longitudinal diachronous closure" from north to south and "transverse diachronous closure" from east to west. The spatial-temporal patterns of the closure process can be summarized as follows: the development of the Bangong-Nujiang Tethyan oceanic lithosphere and its subduction started before the Late Jurassic; after the Late Jurassic, the ocean began to close because of the compressional regime surrounding the BNSZ; along the northern margin of the Bangong-Nujiang Tethyan Ocean, collisions involving the arcs, back-arc basins, and marginal basins of a multi-arc basin system first took place during the Late Jurassic-early Early Cretaceous, resulting in regional uplift and the regional unconformity along the northern margin of the ocean and in the Southern Qiangtang Terrane on the northern side of the ocean. However, the closure of the Bangong-Nujiang Tethyan Ocean cannot be attributed to these arc-arc and arc-continent collisions, because subduction and the development of the Bangong-Nujiang Tethyan oceanic lithosphere continued until the late Early Cretaceous. The gradual closure of the middle and western segments of Bangong-Nujiang Tethyan Ocean was diachronous from east to west, starting in the east in the middle Early Cretaceous, and being mainly

Full Text Available The article stated that to determine the specifics of a middle class it is necessary to apply economic and mathematical methods allowing one to display a certain proportion and sometimes qualitative patterns of distribution of different forms and types of settlement and problems that are investigated. The key components of each factor can be determined based on the analysis of factor analysis and the indicators playing a major role in shaping sets of factors can be shown based on a factor variance. The spatial organization of society in this research study has been noted to have a multi-level character, because it is going to cover the territory within the regions and the accommodation of diverse population on it will include spatial distribution of various types of economic activity and economic indicators. In this study, the special attention has been paid to economic poverty to determine the boundaries of the middle class, and conduction of more accurate inequality of economic indicators in the regions. The regional specifics of the Capital socio-geographical area has been conducted through socio-geographical approach aimed at disclosing the middle class. Based on statistical data systematization, the analysis has been conducted due to the matrix factorization of selected indicators intercorrelation. It has been noted that the study of the middle class from the standpoint of social geography as spatially conditioned phenomenon requires the formulation of methodological regulations, it defines procedures for research highlighting the main stages, and it studies the techniques and methods of forming the system of scientific research to further disclosure issues.

Statistical Inference on the Canadian Middle Class

Directory of Open Access Journals (Sweden)

Russell Davidson

2018-03-01

Full Text Available Conventional wisdom says that the middle classes in many developed countries have recently suffered losses, in terms of both the share of the total population belonging to the middle class, and also their share in total income. Here, distribution-free methods are developed for inference on these shares, by means of deriving expressions for their asymptotic variances of sample estimates, and the covariance of the estimates. Asymptotic inference can be undertaken based on asymptotic normality. Bootstrap inference can be expected to be more reliable, and appropriate bootstrap procedures are proposed. As an illustration, samples of individual earnings drawn from Canadian census data are used to test various hypotheses about the middle-class shares, and confidence intervals for them are computed. It is found that, for the earlier censuses, sample sizes are large enough for asymptotic and bootstrap inference to be almost identical, but that, in the twenty-first century, the bootstrap fails on account of a strange phenomenon whereby many presumably different incomes in the data are rounded to one and the same value. Another difference between the centuries is the appearance of heavy right-hand tails in the income distributions of both men and women.

The Fermilab Main Injector (FMI) project is the centerpiece of the Laboratory's Fermilab III programme for the 1990s. Designed to support a luminosity of at least 5x10{sup 31} cm{sup -2} s{sup -1} in the Tevatron collider, it will also provide new capabilities for rare neutral kaon decay and neutrino oscillation studies. The Fermilab Main Injector 8-150 GeV synchrotron is designed to replace the existing Main Ring which seriously limits beam intensities for the Tevatron and the antiproton production target. The project has passed several significant milestones and is now proceeding rapidly towards construction. The project received a $11.65M appropriation in 1992 and has been given $15M for the current fiscal year. Through the Energy Systems Acquisition Advisory Board (ESAAB) process, the US Department of Energy (DoE) has authorized funds for construction of the underground enclosure and service building where the Main Injector will touch the Tevatron, and to the preparation of bids for remaining project construction.

Genetic and Environmental Architecture of Changes in Episodic Memory from Middle to Late Middle Age

Episodic memory is a complex construct at both the phenotypic and genetic level. Ample evidence supports age-related cognitive stability and change being accounted for by general and domain-specific factors. We hypothesized that general and specific factors would underlie change even within this single cognitive domain. We examined six measures from three episodic memory tests in a narrow age cohort at middle and late middle age. The factor structure was invariant across occasions. At both timepoints two of three test-specific factors (story recall, design recall) had significant genetic influences independent of the general memory factor. Phenotypic stability was moderate to high, and primarily accounted for by genetic influences, except for one test-specific factor (list learning). Mean change over time was nonsignificant for one test-level factor; one declined; one improved. The results highlight the phenotypic and genetic complexity of memory and memory change, and shed light on an understudied period of life. PMID:25938244

The book analyses, clarifies and summarises, from various aspects, some of the many questions concerning the motivation, the meaning, the economics, the dangers and the risks of introducing nuclear technology into the Middle East area following the recent agreements between some Mid Eastern countries and the United States, France, Germany and the U.S.S.R. about the supply of nuclear power reactors and nuclear fuel to the Middle East. The recent strong nuclear prgrams of countries such as India and Iran, who have wide-ranging ties with the Mid-Eastern countries, coupled with the huge revenues of petrodollars by the Arab countries of the area, together with the dangers of another 1973-type oil embargo are discussed and the triple crises of energy, ecology and nuclear weapons proliferation are considered.
