According to the temperature distribution of water injection well-bore in highly deviated wells under different conditions and unstable temperature field heat conduction principles, a true three-dimensional model was established to analyze the law of variation on temperature of highly deviated wells during the water injection process, and to analyze the factors that influence the water injectio...

Objective: Ageing of the stored seed is a natural phenomenon and the seeds tend to lose viability even under ideal storage conditions. Accelerated ageing has been recognized as a good predictor of the storability of seed lots. Aged seeds show decreased vigor and produce weak seedlings that are unable to survive once reintroduced into a habitat. The characteristics of the chemical composition of...

background& objectives: inspite of intensive worldwide efforts to reduce its transmission, malaria remains the most serious and widespread protozoal infection of humans. it is a protozoan disease transmitted by the bite of infected female anopheles mosquito. malaria has long featured prominently in the grey area between parasitology and hematology. this study has been performed to evaluate ...

INTRODUCTION Clinical nonfunctional pituitary microadenomas, also known as incidentalomas are accidental observations made due to the application of high resolution imaging techniques as computed tomography or magnetic resonance. There are no standards regarding the follow-up of these tumors and taking into account their increased frequency among general population (during the last years they w...

PURPOSE Our study documents how the divorce rate among persons aged 50 and older has changed between 1990 and 2010 and identifies the sociodemographic correlates of divorce among today's middle-aged and older adults. DESIGN AND METHOD We used data from the 1990 U.S. Vital Statistics Report and the 2010 American Community Survey (ACS) to examine the change in the divorce rate over time. ACS da...

Births According to provisional reports, an estimated 300,000 births occurred in the United States during December 1995. This was a decrease of 4 percent from the provisional number of births reported for December 1994 (314,000). The birth rate, 13.4 live births per 1,000 population, was 5 percent lower than the rate of 14.1 for December 1994. The fertility rate, 59.3 live births per 1,000 wome...
