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.

Incorporation of High-Altitude Balloon Experiment in High School Science Classrooms

High-altitude balloon is a balloon, filled usually with helium or hydrogen that ascends into an area called “near space” or stratosphere. The most common type of high-altitude balloons are weather balloons. Other purposes include use as a platform for experiments in the upper atmosphere. Modern balloons generally contain electronic equipment such as radio transmitters, cameras, or satellite navigation systems, such as GPS receivers. The mission of the High-Altitude Balloon Experiment (HABE) is to acquire supporting data, validate enabling technologies, and resolve critical acquisition, tracking, and pointing (ATP) and fire control issues in support of future space-based precision pointing experiments. The use of high-altitude balloons offers a relatively low-cost, low-vibration test platform, a recoverable and reusable payload, worldwide launch capability, and a 'near- space' emulation of the future space systems operational scenarios. More recently, several university...

Location Optimization of a Coal Power Plant to Balance Costs against Plant’s Emission Exposure

Fuel and its delivery cost comprise the biggest expense in coal power plant operations. Delivery of electricity from generation to consumers requires investment in power lines and transmission grids. Placing a coal power plant or multiple power plants near dense population centers can lower transmission costs. If a coalmine is nearby, transportation costs can also be reduced. However, emissions from coal plants play a key role in worsening health crises in many countries. And coal upon combustion produces CO 2 , SO 2 , NO x , CO, Metallic and Particle Matter (PM10 & PM2.5). The presence of these chemical compounds in the atmosphere in close vicinity to humans, livestock, and agriculture carries detrimental health consequences. The goal of the research was to develop a methodology to minimize the public’s exposure to harmful emissions from coal power plants while maintaining minimal operational costs related to electric distribution losses and coal logistics. The objective was...

Effects of Karate Training on Basic Motor Abilities of Primary School Children

“You never attack first in karate” might be the best conclusion of karate, which is a martial art practiced typically without weapons. It’s reported that karate has a long history for several hundred years, but the modern karate was spread to the whole Japan from Okinawa in the early part of 20th century. Now it has become one of the most widely practiced martial art forms in the world. Usually, it’s divided into Kihon, Kata and Kumite. As for the beginners, Kihon is more suitable for them because it involves basic techniques. Due to karate consists of dynamic offensive and defensive techniques using all parts of the body to their maximum advantage, the best understanding of true karate practice is the perfection of oneself through the perfection of the art. It not only develops coordination, quickens reflexes, and builds stamina, but also develops composure, a clearer thought process, deeper insight into one’s mental capabilities, and more self-confidence. So many researchers stu...
