The article chose review is “Effect of exercise training on loss of bone mineral density during lactation”. The purpose of this study was to determine whether exercise slows bone loss from four to twenty postpartum. The problem was that during lactation women move breast milk. After finishing breast feeding bone mass usually returns to pre pregnancy but not in all and this is the problem. The participants were healthy ‚nonsmoking ‚ sedentary ‚exclusively breast feeding women with a body mass index

population density of major insect pest as influenced by spatial arrangement in pechay by ABSTRACT Spatial arrangement in pechay production could be used as an strategic pest management. Three different spacing were used to determine the effects of spatial arrangement in the population density of pechay. The spacing were 2.5 x 5 in‚ 3.5 x 5 in and 5 x 5 in per plant. Collections of insect pests were done starting five days after transplanting and continued every three days until harvest. Damage

Hong Kong Housing Problem is not only attributed to the High Population Density Every Hong Kong citizen knows one of the grave troubles in Hong Kong is housing problem. The order of severity can be apparently reflected by many figures in recent research studies. ”Rents up 22 per cent in Hong Kong“ (2011) remarks that “the price of renting two-bedroom accommodation rose by 22% to US$2‚830 a month between 2009 and 2010“ (¶2).

Effects of megasonic power in DIW rinsing on particle removal efficiency and defect density Abstract- As the IC fabrication feature size gets smaller‚ the particle removal process becomes a critical step. It was proven that megasonic in SC-1 chemical is effective in removing surface contaminants but might inflicting structure damage [1-2] especially for geometry smaller than 130nm technology. Since Moore’s law states that the number of transistor on an IC chip will be double every two years

found on the bottom surface of leaves. The number of stomata on a leaf’s surface can tell you a lot about the plant itself. Most often‚ a higher stomata density indicates a high amount of sun exposure and an abundance of moisture available to the roots. A lower stomata density indicates higher amounts of carbon dioxide. In other words‚ stomata density is determined by the conditions that the plant experiences while the leaf is developing. During photosynthesis‚ stomata take in carbon dioxide (CO2)
