BACKGROUND Prior animal and human studies of prenatal exposure to solvents including tetrachloroethylene (PCE) have shown increases in the risk of certain congenital anomalies among exposed offspring. OBJECTIVES This retrospective cohort study examined whether PCE contamination of public drinking water supplies in Massachusetts influenced the occurrence of congenital anomalies among children ...
one of the most commonly used techniques to reduce the corrosion rate of rebar in concrete is addition substances named corrosion inhibitors into the concrete. corrosion inhibitor is chemical compounds that were added to concrete to prevent corrosion of steel in concrete. sodium nitrate is a type of anodic inhibitors that this study investigatesthe effect of this inhibitor on the properties of ...
UĞURLU, M., I. KAYA and M. SARAY, 2016. Effects of some environmental factors on calf birth weight and milk yield of Anatolian Water Buffalo (Bubalus bubalis). Bulg. J. Agric. Sci., 22: 995–998 This research was conducted to determine the effects of some environmental factors on calf birth weight, milk yield and lactation length in Anatolian Water Buffalo. The data on birth weight of 1006 buffa...
BACKGROUND More than 95% of neonatal deaths occur in developing countries, approximately 50% at home. Few data are available on the impact of hand-washing practices by birth attendants or caretakers on neonatal mortality. OBJECTIVE To evaluate the relationship between birth attendant and maternal hand-washing practices and neonatal mortality in rural Nepal. DESIGN Observational prospective ...
Contextual determinants of neonatal mortality using two analysis methods, Rio Grande do Sul, Brazil.
OBJECTIVE To analyze neonatal mortality determinants using multilevel logistic regression and classic hierarchical models. METHODS Cohort study including 138,407 live births with birth certificates and 1,134 neonatal deaths recorded in 2003, in the state of Rio Grande do Sul, Southern Brazil. The Information System on Live Births and mortality records were linked for gathering information on ...
lthough only a relatively small proportion of women give birth in water, many more use birthing pools during labour. Most UK maternity units have plumbed birthing pools, as well as portable ones used for home births. For some women, labour and birth in water are important features of their birth plans – but this is not available for all women. The Royal College of Obstetricians and Gynaecologis...
Human consumption is depleting the Earth's natural resources and impairing the capacity of life-supporting ecosystems. Humans have changed ecosystems more rapidly and extensively over the past 50 years than during any other period, primarily to meet increasing demands for food, fresh water, timber, fibre and fuel. Such consumption, together with world population increasing from 2.6 billion in 1...
OBJECTIVE To understand how social context affects the nutritional status of populations, as reflected by the prevalence of wasting in children under 5 years of age from Africa, Latin America, and Asia; to present a systematic way of building models for wasting prevalence, using a conceptual framework for the determinants of malnutrition; and to examine the feasibility of using readily availabl...
An experiment using 81 crossbred swine was conducted to evaluate quantitative and percentage chemical compositional changes of swine from 1.5 kg (birth) to 145 kg body weight. Groups of eight pigs were sacrificed at 1.5, 6.4 and 18 kg, and then at 18 kg increments to 145 kg. Body composit ion was determined by grinding the entire body, minus digesta, partit ioning the carcass from other body co...
Our objective was to examine the relationship between estimated maternal exposure to pesticides in public drinking water and the risk of congenital heart defects (CHD). We used mixed-effects logistic regression to analyze data from 18,291 nonsyndromic cases with heart defects from the Texas Birth Defects Registry and 4414 randomly-selected controls delivered in Texas from 1999 through 2005. Wat...
