Inetial electrostatic confinment fusion (IECF) device constructed at the Egyptian Atomic Energy Authority (EAEA-IEC), is introduced the characterization of the IEC plasma device. The x-ray and visible light emissions in IEC plasma device were investigated by employing time -resolved detector and measure of the total amount of visible light using lux meter

People and climate: holocene sediment records of environmental change in Middle Egypt: fieldwork report and initial results

The aim of this project is to reveal more about the history of Lake Qarun through a multidisciplinary environmental study. This approach primarily concerns the examination of sediment records, but also includes collection of data from archaeological sites in the Faiyum. The sedimentary history of Lake Qarun will be compared with (i) independent palaeoclimate records for the East African Highlands and the eastern Mediterranean; (ii) local evidence (including Nile alluvial and palaeo-shoreline sequences and Holocene playa deposits); and (iii) the cultural history of the Faiyum. This report describes the fieldwork performed to obtain long sediment cores for palaeolimnological analysis and presents initial results from those cores. Results will be used to construct a Geographical Information System (GIS)

Narghile (water pipe) smoking among university students in Jordan: prevalence, pattern and beliefs

<p>Abstract</p> <p>Background and objectives</p> <p>Narghile is becoming the favorite form of tobacco use by youth globally. This problem has received more attention in recent years. The aim of this study was to investigate the prevalence and pattern of narghile use among students in three public Jordanian universities; to assess their beliefs about narghile's adverse health consequences; and to evaluate their awareness of oral health and oral hygiene.</p> <p>Methods</p> <p>The study was a cross-sectional survey of university students. A self-administered, anonymous questionnaire was distributed randomly to university students in three public Jordanian universities during December, 2008. The questionnaire was designed to ask specific questions that are related to smoking in general, and to narghile smoking in specific. There were also questions about oral health awareness and oral hygiene practices.</p> <p>Results</p> <p>36.8% of the surveyed sample indicated they were smokers comprising 61.9% of the male students and 10.7% of the female students in the study sample. Cigarettes and narghile were the preferred smoking methods among male students (42%). On the other hand, female students preferred narghile only (53%). Parental smoking status but not their educational level was associated with the students smoking status. Smokers had also significantly poor dental attendance and poor oral hygiene habits.</p> <p>Conclusion</p> <p>This study confirmed the spreading narghile epidemic among young people in Jordan like the neighboring countries of the Eastern Mediterranean region. Alarming signs were the poor oral health awareness among students particularly smokers.</p

Prevalence, associated factors and outcomes of pressure injuries in adult intensive care unit patients: the DecubICUs study

Funder: European Society of Intensive Care Medicine; doi: http://dx.doi.org/10.13039/501100013347Funder: Flemish Society for Critical Care NursesAbstract: Purpose: Intensive care unit (ICU) patients are particularly susceptible to developing pressure injuries. Epidemiologic data is however unavailable. We aimed to provide an international picture of the extent of pressure injuries and factors associated with ICU-acquired pressure injuries in adult ICU patients. Methods: International 1-day point-prevalence study; follow-up for outcome assessment until hospital discharge (maximum 12 weeks). Factors associated with ICU-acquired pressure injury and hospital mortality were assessed by generalised linear mixed-effects regression analysis. Results: Data from 13,254 patients in 1117 ICUs (90 countries) revealed 6747 pressure injuries; 3997 (59.2%) were ICU-acquired. Overall prevalence was 26.6% (95% confidence interval [CI] 25.9–27.3). ICU-acquired prevalence was 16.2% (95% CI 15.6–16.8). Sacrum (37%) and heels (19.5%) were most affected. Factors independently associated with ICU-acquired pressure injuries were older age, male sex, being underweight, emergency surgery, higher Simplified Acute Physiology Score II, Braden score 3 days, comorbidities (chronic obstructive pulmonary disease, immunodeficiency), organ support (renal replacement, mechanical ventilation on ICU admission), and being in a low or lower-middle income-economy. Gradually increasing associations with mortality were identified for increasing severity of pressure injury: stage I (odds ratio [OR] 1.5; 95% CI 1.2–1.8), stage II (OR 1.6; 95% CI 1.4–1.9), and stage III or worse (OR 2.8; 95% CI 2.3–3.3). Conclusion: Pressure injuries are common in adult ICU patients. ICU-acquired pressure injuries are associated with mainly intrinsic factors and mortality. Optimal care standards, increased awareness, appropriate resource allocation, and further research into optimal prevention are pivotal to tackle this important patient safety threat

Microwave-assisted synthesis of micro/nano Nd-O powders

This paper reports the synthesis of Nd-2(C2O4)(3)center dot 10H(2)O with plate-like morphology employing the microwave-assisted precipitation as a new strategy. Thermogravimetric analysis (TGA-DTG) results supported the presence of 10 water molecules of hydration of the prepared neodymium oxalate, which decomposes to give neodymium oxide (Nd2O3) as a final product throughout the dioxy-carbonate intermediate formation. Based on its thermal behaviour, portions of the prepared neodymium oxalate were heated non-isothermally, utilizing a similar heating rate to that used in the TGA experiment, at the range 400-800 degrees C, then quenched to room temperature. Phase characterization indicated the formation of an amorphous carbonate phase at 400 degrees C, which crystallizes at 500 degrees C giving the hexagonal Nd2O2CO3 phase. The formed Nd2O3 at the range 700-800 degrees C was found to have a high ability to absorb atmospheric water vapour forming Nd(OH)(3). The electrical conductivity measurements revealed strong dependence on the pre-treatment temperature, where the Nd-600 sample showed the highest values. The fluorescent properties of the pre-heated solids revealed the absence of a notable peak shift and fluorescence behaviour of the various samples was correlated with the structure modifications occurring during the pre-treatment.Web of Science95104901047
