background: calcium is the most abundant mineral in the human body. this mineral is provided only by the consumption of foods containing calcium that it is recommended to use at least1300 mg daily for adults. this study is aimed to investigate the nutritional behavior of female high school students about consumption of calcium-rich foods.materials and methodsat a descriptive-analytical study, t...

abstract background: to determine daily calcium, vitamin d intake and serum biochemical findings of rickets in adolescent girls. methods: a total of 414 healthy adolescent student girls aged 11-15 years were evaluated from various areas of tehran, iran with different socioeconomic status. a randomized, cross-sectional, prospective and descriptive study was undertaken for calculation of daily ca...

optimization of reservoir parameters is an important issue in petroleum exploration and production. the ant colony optimization(aco) is a recent approach to solve discrete and continuous optimization problems. in this paper, the ant colony optimization is usedas an intelligent tool to estimate reservoir rock properties. the methodology is illustrated by using a case study on shear wave velocity...

background: calcium (ca+2) plays an important role in many biophysiological mechanisms .the present study was carried out to assess alterations in total serum calcium level before and after operations in consider to the type of anesthesia. materials and methods: this descriptive study was conducted on 74 women who candidate for gynecological abdominal operations during one year at al-zahra mate...

Background: BCS class II and IV drugs, which have low solubility, provide a number of challenges for formulation scientists working on oral delivery of drugs. Aims: The aim and purpose of the present work was to design a gel liquisolid tablets for Atorvastatin calcium a water insoluble drug to increase its dissolution rate there by its bioavailability. Materials and Methods: The preformulation ...

Calcium doped nickel ferrite powders have been prepared by sol-gel combustion technique. Metal nitrates, such as calcium nitrate, nickel nitrate and ferric nitrate, were used as the source materials and citric acid and polyvinyl alcohol were used as the burning agent and agglomeration reducing agent, respectively. The average crystallite size of the prepared ferrite was in the order of ~70- 92 ...
