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 RAIN WATER HARVESTING AND ARTIFICIAL RECHARGE TO GROUND WATER WHAT IS RAIN WATER HARVESTING : The principle of collecting and using precipitation from a catchments surface. An old technology is gaining popularity in a new way. Rain water harvesting is enjoying a renaissance of sorts in the world‚ but it traces its history to biblical times. Extensive rain water harvesting apparatus existed 4000 years ago in the Palestine and Greece. In ancient Rome‚ residences

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

The Ethical Issues Of The Loeb Vs. Vergara Embryo Dispute This paper seeks to answer questions raised by Nick Loeb’s “Sofia Vergara’s Ex-Fiancé: Our Frozen Embryos Have a Right to Live” (The New York Times‚ 29 April 2015). The key issues identified in his article are the importance of family‚ procreation‚ pro-life vs. pro-choice‚ and moral duty. In my evaluation of these issues‚ I believe that the rights of a person may outweigh another. The prospects of what is a “Good” family life for the child

Available online at www.wateraid.org/ technologies January 2013 Introduction Where there is no surface water‚ where groundwater is deep or inaccessible due to hard ground conditions‚ or where it is too salty‚ acidic or otherwise unpleasant or unfit to drink‚ another source must be sought. In areas that have regular rainfall‚ the most appropriate alternative is the collection of rainwater‚ called
