BACKGROUND The objectives of this study were to determine rates of prenatal care utilization in Winnipeg, Manitoba, Canada from 1991 to 2000; to compare two indices of prenatal care utilization in identifying the proportion of the population receiving inadequate prenatal care; to determine the association between inadequate prenatal care and adverse pregnancy outcomes (preterm birth, low birth ...

in order to investigate the effects of different levels of nitrogen rate on yield and seed yield components of wheat cultivars, an experiment was conducted on araghi mahalleh (gorogan) research farm in 2008. treatments, nitrogen in the form of urea (0, 90, 180 and 270 kg/ha) and cultivars (tajan, falat and n81-18) were arranged as factorial based on randomized complete block design with four re...

background and objectives: in the era of global industrialization, enzymes are being used extensively in the various sectors including food processing. owing to the high price of enzymes, various initiatives have been undertaken by the r&d; sector for the development of new processes or improvement in the existing processes for production of cost effective enzymes. with the advancement in the f...

Four pepper genotypes classified as resistant and four pepper genotypes classified as susceptible to several avirulent populations of M. incognita were compared for their reactions against a population of Meloidogyne incognita (Chitwood) Kofoid and White which had been shown to be virulent to resistant bell pepper (Capsicum annuum) in preliminary tests. The virulent population of M. incognita o...

CONTEXT Two measures traditionally used to examine adequacy of prenatal care indicate that prenatal care utilization remained unchanged through the 1980s and only began to rise slightly in the 1990s. In recent years, new measures have been developed that include a category for women who receive more than the recommended amount of care (intensive utilization). OBJECTIVE To compare the older an...

Protein. starch. fat. sucrose. glucose. and fructose contents were analyzed in 22 com genotypes and correlated with food utiliz'ltion panlmeters and indices determined on developing rice weevil. Sirophillls 01}'zae (L.), reared on each com genotype. The larval period was reduced and heavier pupae developed from com with higher glucose content. Increascd levels of prOiein reduced amount of food ...

This review described the physiological and biochemical effects of various secondary metabolites from Meliaceae against major Lepidopteran insect pest including, Noctuidae and Pyralidae. The biochemical effect of major Meliaceae secondary metabolites were discussed more in this review. Several enzymes based on food materials have critical roles in nutritional indices (food utilization) of the i...

plant life and food production for human closely depend on fertile and healthy soil. knowledge about qualitative properties of soil and its potential production can contribute us in the plantation, fertilization, utilization and land management. in addition, rangelands cover a very large portion of the earth's surface and play an important role in food security and other ecosystem services. the...
