the need for a mothers’ womb or a sergeant mother‚ in what they are calling “the new fashioned way”: growing the embryo in an artificial womb. Doctors are developing artificial wombs in which embryos can grow outside woman’s body. The work has been hailed as a breakthrough in treating the childless. Scientists have created prototypes made out of cells extracted from women’s bodies. Embryos successfully attached themselves to the walls of these laboratory wombs and began to grow. However‚ experiments

FREEZING FOODS 1. Freezing storage space is valuable. Use it only for high quality meats‚ fruits and vegetables. Do not freeze and store excessively bulky products. 2. Place a variety of foods in your locker or home freezing unit. Avoid long storage of any items. Add new items as rapidly as storage space will permit. 3. If your locker plant or home-unit has a quick-freeze compartment‚ use it. The temperature of this compartment should be held at 0 or below. The time required for freezing should not

melt. This only works‚ however‚ if the temperature outside is at or near freezing. If it is too cold outside‚ the ice itself becomes very dry and salt is not as effective in melting it. Salt Reduces Freezing Temperature of Water * Salt works by lowering the freezing temperature of water. Salt water needs to reach a colder temperature than pure water to freeze. This is why salted ice on roads that are near the freezing temperature of pure water (32 degrees Fahrenheit) will melt and not refreeze

RAIN WATER HARVESTING INTRODUCTION 1. Urban centres in India are facing an ironical situation today. On one hand there is the acute water scarcity due to rise in consumption‚ over dependence and over-exploitation of ground water resources. Added to this‚ there is a lack of a coherent and credible water management policy. On the other hand‚ the streets are often flooded during the monsoons‚ giving rise to a situation of ‘water‚ water everywhere‚ and not a drop to drink.’ 2. This shortage

Rainwater harvesting is the accumulation and deposition of rainwater for reuse before it reaches the aquifer. Uses include water for garden‚ water for livestock‚ water for irrigation‚ etc. In many places the water collected is just redirected to a deep pit with percolation. The harvested water can be used for drinking water as well if the storage is a tank that can be accessed and cleaned when needed. advantages • Makes use of a natural resource and reduces flooding‚ storm water runoff‚ erosion

January 9‚ 2014 Regulations in the Rights Involving the Ownership of Frozen Embryos One in eight couples in the United States face the problem of infertility (Erickson‚ Erickson). These couples cannot produce a child through intercourse‚ but if they wish to have a child of their own they need to look for other options. These options are referred to as assisted reproduction technologies‚ or otherwise known as “ART” (Erickson‚ Erickson). The technologies included in ART are in vitro fertilization

Embryo transfer in cattle has gained considerable popularity with seed stock beef producers. While most modern applicable embryo transfer technology was developed in the 1970s and 1980s‚ the history of the procedure goes back considerably farther. ‘‘Walter Heape performed the first embryo transfer in Angora rabbits in 1890’’ (J.C. Remsberg‚ ‘Herdsmen and vets benefit from E.T. training’). ‘‘Embryo transfer in livestock began in the 1930s with sheep and goats‚ but it was not until the 1950s that Jim
