Determination of Iron in Baby Weaning Food and Powder Milk

Iron is a mineral that’s necessary for life. Essentially, it is responsible for carrying oxygen in your red blood cells and transmitting nerve impulses. And it is necessary for growth, development, normal cellular functioning, and synthesis of some hormones and connective tissue. Commonly, not having enough iron in the body leads to anemia. According to research, it has been found that a man needs an average daily intake pf 7 mg of iron and a woman 11 mg; and a normal diet will generally provide all that is needed. As for babies, they usually get needed iron from breast milk for the first 6 months. At around 6 months, they will need iron-rich complementary foods as well as breast milk.

Based on the important roles of iron in human bodies, the authors in this study determined the concentration of iron in baby weaning food and powder milk available in Iran. The concentration of iron in four brands of powder milk and baby food (based on rice and based on wheat) was analyzed with differential pulse anodic stripping voltammetry (DPASV) and voltammeter device. Total Means ± SE of Iron in baby foods and powder milk (n = 40) were 8.55 ± 1.18 mg/100g, 5.21 ± 0.66 respectively. Iron level in baby food type I and II was lower than labeled value (p < 0.05). Concentration of Iron in powder milk type I and II was also lower than value of label (p < 0.05). All in all, the amount of iron in the samples was less than the amount printed on cans that had milk and baby food. It seems to be more precise control of baby food for health and child development.

Finally, through this study, more attention should be given to: iron intake by breast-fed infants; recommendations for iron supplements; the distribution of iron in milk-binding factors; and the bioavailability of iron from breast milk.

Does Immigration Promote the Investment of the Monopolistic Firm?

In the present paper, we examine the effect of increasing uncertainty of immigrants’ growth on the optimal timing of investment of a firm that has a monopolistic power over the labor market. It is revealed that when the uncertainty of immigrants’ growth is more than a threshold level, increasing uncertainty of immigrants’ growth accelerates the optimal timing of firms’ investment and enhances the economic growth, even if the uncertainty of immigrants’ growth is formulated by the geometric Brownian motion, which is in sharp contrast to the standard result that an increase in the uncertainty postpones the optimal timing. With an increase in the immigrants over the past ten years, workforces in the host countries have been growing significantly to the extent that the immigrants represent 70% of the increase in the workforce in Europe, and 47% in the United States as OECD indicates. In the present paper, we attempted to investigate the effect of increased uncertainty caused by the growi...

Education Policy Implementation: A Mechanism for Enhancing Primary Education Development in Zanzibar

Education is one of the fundamental rights of individuals; therefore, the government of a country needs to develop and strengthen educational policy and quality as well as to ensure that everyone has equal access to basic education. The improvement of access and quality of education in the world is becoming as an essential factor in development, whereas the basic education (primary school), is acknowledged as a foundation of the higher educational development for every country. To fulfill this goal, governments introduce several policies and procedures; however, it requires some reforms and participation from the politician, policymakers, and other stakeholders to re-examine educational policy so that it can lead to multiplication and betterment of the reforms. Educational reforms actually focus on accountability. A positive educational development and reform is very challenging and needs more effort and strategy on how to use and utilize the resources effectively as such it can achie...
