background: iron deficiency is the most frequent cause of nutrition problems around the world. this investigation performed in order to determine the prevalence of iron deficiency in the last three months of pregnancy in women who referred to the kerman health centers, in 1999. methods: the sample size was estimated 350 based on a pilot study. the sampling technique was cluster random sampling ...

fischer-tropsch catalysts with high activity and selectivity for olefins were produced using mordenite type sio2/al2o3= 12, 20, 28, 62 zeolite supported iron carbonyl compounds and were characterized by x-ray powder diffraction. the adsorptionof volatile fe(co)5 on the support surface was carried out under vacuum at room temperature. reduction les were monitored by vibrating sample magnetometer...

BACKGROUND Short-term measurements of iron absorption are substantially influenced by dietary bioavailability of iron, yet bioavailability negligibly affects serum ferritin in longer, controlled trials. OBJECTIVE Our objective was to test the hypothesis that in men fed diets with high or low iron bioavailability, iron absorption adapts to homeostatically maintain body iron stores. DESIGN He...

Background: Legumes are plants that contain edible seeds and belong to the family Leguminosae with varying nutritional benefits to humans and animals. This study aimed to detect and identify toxicogenic molds on some legumes purchased from two local markets in Ho Municipality, Ghana. Methods: A total of 36 samples, including cowpea (n=9), soybean (n=9), brown bean (n=9), and Bambara bean (n=9)...

In Sangan iron mine nearly two million tons of low-grade iron ore has been extracted and deposited in the mining site and currently no action is made on them. On the other hand, the mining site is located in the semi-arid region and wet processing has been restricted due to water shortage. In this research, the upgradation of Sangan low-grade iron ore from mine B has been performed by dry low-i...

in this paper, iron ore sample from the chadormalu was investigated to determine some comminution properties. chadormalu deposit is one of the largest iron ore mine in iran, which is located in yazd province. the representative ore sample contained 57%fe, 0.9%p and 0.17%s. the sample was crushed; afterward, it was ground in various grinding times according to the bond ball mill approach to spec...
