protein hydro-lysate was prepared from gold striped sardine (sardinella gibossa) by papain. hydrolysis conditions (time, temperature, and enzyme activity) were optimized by response surface methodology (rsm) using a factorial design and anti-oxidative activity was the dependent variable. results of the total determination coefficient, adjusted r2 and predicted r2 indicating the validity of pred...

An improvement of the Piringer model, allowing the prediction of a worst case migration from packaging to food is presented here. The authors are proposing other constants for the calculation of the upperbound value of the diffusion coefficient, using experimental data determined by a film to film method. Considering the plasticizing effects of food simulants, a model involving the variation of...

Background and purpose: Utilization of health care services and food influence the health status. The food and health care expenditure ratios determine the importance level of them in household's consumption expenditures. We aimed to investigate the Iranian rural and urban food and health expenditure ratios inequality during 1998 to 2012. Materials and Methods: This is a descriptive longitudina...

Some statistics in common use take a form of a ratio of two statistics such as sample correlation coefficient, Pearson’s coefficient of variation and so on. In this paper, obtaining an asymptotic representation of the ratio statistic until the third order term, we will discuss asymptotic mean squared errors of the ratio statistics. We will also discuss bias correction of the sample correlation ...

Background and Objectives: This study was undertaken to determine the relationship between food security and individual dietary diversity score (IDDS). Materials and Methods: This population-based cross-sectional study was conducted on 200 non-diabetic individuals aged ≥40 years, selected randomly from the Tehran Lipid and Glucose Study. Household food security was measured using a validated U...

objective: for investigation of intercropping of maize and faba bean, an experiment was conducted in research station of agriculture faculty of tabriz university during growing season of 2013. methods: experimental design was randomized complete block design with three replications and seven treatment. treatments included one row intercropping (1:1), 4 strip intercropping pattern with ratios of...

A theory model was established to calculate the magnetoelectric voltage coefficient of piezoelectric/piezomagnetic laminated composites on silicon or magnesium oxide substrates. The magnetoelectric voltage coefficient is calculated as function of interface coupling factor k, volume ratio of piezoelectrics to piezomagnetic, and volume ratio of substrates to composite. It was found that the magne...
