considering the seepage and choosing an efficient sealing method is very important in dam projects. this issue has a close relationship with engineering geological properties of the dam site. chapar-abad dam is an inhomogeneous earth-fill dam of 44.5 meters height, crest length about 427 meters and a reservoir capacity of 127 million cubic meters. the dam project is under construction and is lo...

Rabbit blastocysts were homogenized by sonication, and centrifuged at 105 000 g for 60 min. The pellet was resuspended and incubated in phosphate buffer containing [1 beta-3H]testosterone and a NADPH generating system. The amount of 3H2O produced was determined by liquid scintillation counting. Enzyme activity was calculated, after subtracting blank values obtained with boiled embryos, and expr...

Methods : numbers of admissions in the period 1984–1995 were obtained from Dutch bases of the National Hospital Institution (NZi). From SIG Health Care Information numbers were obtained with regard to ...

Sucrose uptake was studied in isolated, immature pea cotyledons (Pisum sativum L. cv Marzia) in relation to their developmental stage. During the developmental period examined the water content of the cotyledons decreased from approximately 80% "stage 1" to approximately 55% "stage 2". When assayed in an isotonic medium (400 osmoles per cubic meter) the influx capacity per gram fresh weight for...

OBJECTIVES To investigate the associations between changes in indicators of health-related resources and coverage, and variations in infant mortality rates (IMR) in Brazil's 27 states in 2000 and 2005. METHODS Data were obtained from the Ministry of Health's online database, DATASUS. Stepwise multiple regressions were performed to model changes in IMR and its components (early, late, and post...

OBJECTIVES To determine the prevalence of obesity among sixth- and seventh-grade students in a school-based setting, and to identify lifestyle parameters associated with obesity. METHODS Sixth- and seventh-grade students (n = 385, 186 boys and 199 girls) from 3 schools participated in a school-based screening study, and 319 completed a short questionnaire. Height and weight were measured, and...

BACKGROUND Physical activity is the only nonpharmacological therapy that is proven to be effective in heart failure (HF) patients in reducing morbidity. To date, little is known about the levels of daily physical activity in HF patients and about related factors. OBJECTIVE The objectives of this study were to (a) describe performance-based daily physical activity in HF patients, (b) compare i...

The construction of strategies for reducing the sodium content of processed foods is part of a set of actions to decrease the intake of this nutrient in Brazil-from the current 12 g of salt per person per day to less than 5 g per person per day (2 000 mg sodium) by 2020. In this process, a central action is the pact between the government and the food industry to establish voluntary, gradual, a...

A total of 4737 cancers were recorded in Kingston and St Andrew during the period 1998 – 2002: 2387 in males and 2350 in females. Age standardized rates per 100 000 per year (ASR) were 188.6 and 144.2 for males and females respectively. In males, the leading sites for cancer were prostate (873 cases), bronchus (269 cases) and large bowel (176 cases) while in females, the leading sites were brea...

16 000 Chrysomyia albiceps and 52 000 C. marginalis adults were radioactively labelled with 32P-orthophosphate and released in the northern Kruger National Park, South Africa. After a 1-week dispersal period 69 baited blow-fly traps were placed in different habitat types and at varying distances around the release point. C. albiceps were subsequently found to have covered up to 37.5 km and C. m...
