The applicability and limitations of sulphur isotope ratio as a nuclear forensic signature have been studied. The typically applied leaching methods in uranium mining processes were simulated for five uranium ore samples and the n(34S)/n(32S) ratios were measured. The sulphur isotope ratio variation during uranium ore concentrate (UOC) production was also followed using two real-life sample set...

Ethanol levels reached in circulation during moderate-to-heavy alcohol intoxication (50–100 mM) modify Caand voltagegated K (BK) channel steady-state activity, eventually altering both physiology and behavior. Ethanol action on BK steadystate activity solely requires the channel-forming subunit slo1 within a bare lipid environment. To identify the protein regions that confer ethanol sensitivity...

for social rather than medical reasons—i.e., in terms of their age, education, ethnicity, marital status, inner-city and rural residence and ability to pay for services.3 This patient profile suggests that midwives are primarily being used to fill health care gaps among the economically disadvantaged. New Medicaid reimbursement regulations could be partially responsible for this relationship,4 ...

linary diagram of power (Davis, 1977; Vatcher, 1965). Indeed, the diagram of the laager— the closed circular formation of ox-wagons used by Voortrekkers when drawing-up battle formation—does, when extrapolated to multiple scales, seem to have been the pre-eminent (spatial) diagram for dealing with threatening forces throughout White South African history —the company garden and fort established...

This review describes historical iodine deficiency in the UK, gives current information on dietary sources of iodine and summarises recent evidence of iodine deficiency and its association with child neurodevelopment. Iodine is required for the production of thyroid hormones that are needed for brain development, particularly during pregnancy. Iodine deficiency is a leading cause of preventable...

Bulgular: PCR esas alındığında, RSV tanısında HAT’ın duyarlılığı %90, özgüllüğü %78.5 idi. RSV pnömonili hastalardan dördünde atriyal septal defekt (ASD) saptandı ve hepsi mekanik ventilasyon desteği gerektirdi. Birinci gün Downes skoru intravenöz sıvı gereksinimi (p= 0.001, r= 0.48), toplam oksijen desteği (p= 0.000, r= 0.63), tekrar beslenmeye başlama süresinin uzunluğu (p= 0.001, r= 0.46) il...
