Vaccine refrigerator runs on evaporation cycles.

Vaccine refrigerator runs on evaporation cycles. Coolar’s solar-powered refrigerators could improve the way vaccines are stored in developing countries.Julia Römer's refrigerators produce cold from heat. Many medicines - from asthma sprays to insulin to vaccines - must be cooled until moments before they're used. But in large parts of the world, electricity is not readily available In a conventional refrigerator, low temperatures are caused by the evaporation of a coolant. In Römer's solar-powered version, the evaporating liquid is water. Her system uses silica gel to attract water after evaporation and create a cycle: a solar panel generates heat that causes the gel to dry, then the water evaporates and is returned to circulation. The solar chiller needs almost no maintenance and is easy to dispose of since it doesn't contain any polluting substances.more

E-cigarettes poison 100 pets.

E-cigarettes poison 100 pets. Gudrun Ravetz, president of the British Veterinary Association said: "E-cigarettes may be harmful if they are ingested by your pet, as e-cigarettes and refills can easily contain sufficient quantities of nicotine to kill a small animal" A large increase of incidents involving e-cigarettes and vitamin D supplements were recorded in recent years.Some 113 pets were poisoned by e-cigarettes while 148 cases involved vitamin D tablets, figures from the Veterinary Poisons Information Service (VPIS) show - however they remain a small percentage of the overall total.more

Natural Pesticide with Chili Peppers.

How to use chilli pepper as natural pesticides. Chili peppers are very strong and insects have a very powerful sense of smell and taste. The chili works to basically fry their senses and causes them pain. They learn from their mistakes and do not bother your produce.

How to use chilli pepper as pesticides.

How to use chilli pepper as pesticides. Chili peppers are very strong and insects (as well as other animals) have a very powerful sense of smell and taste. The chili works to basically fry their senses and causes them pain. They learn from their mistakes and do not bother your produce. Use 20 chili peppers and dry them out. Grind the chili in to a fine dust. Fill a pot with 2 liters of water and add the chili dust. Boil this mixture for roughly 20 minutes. Remove the pot from the stove and add another 2 liters of water then allow it to fully cool. Strain the water through a cheese cloth then add potash soap to it (soft). This allows the spray to stick to the vegetation without hurting it. Fill a spray bottle with this liquid and apply to your plants once a week and twice if there is rain. A chili pepper can be an insecticide as well as a deterrent for other animals to ravage your crops. Many of us have to worry about groundhogs, rabbits and skunks. You can create a barrier that these animals will not willingly cross. As soon as they get a scent or a taste they will be disgusted and made ill. It will not kill them but will make them feel incredibly unpleasant. Get dried chili peppers and grind them to dust. Sprinkle the dust around the vegetation.more

How the bumblebee coincidentally saved the greenhouse industry.

How the bumblebee coincidentally saved the greenhouse industry.Bumblebees, beneficial insects and mites are probably the most loyal residents of a grower's greenhouse. The Belgian veterinarian who made this discovery was Roland De Jonghe. He had always been fascinated by the world of bumblebees and was breeding them in his living room, backyard and garage as a hobby. One day, De Jonghe saw a bumblebee accidentally pollinating a tomato crop in one of his friend's hobby greenhouses in the early eighties. The veterinarian immediately realized that if he succeeded in bringing more bumblebees into a greenhouse, growers could make a giant leap forward and replace manual pollination. De Jonghe became the first to breed and produce bumblebees year-round, and soon after his company Biobest was born. Thirty years later, the Belgian company operates more than fourteen international subsidiaries and has distributors in over sixty countries. On a weekly basis, about 700,000 bumblebees leave their production facilities in Westerlo, on their way to help a desperate greenhouse grower pollinate his crops somewhere on the other side of the world. more

AGRIBUSINESS :Biopesticides and the benefits in agribusiness.

AGRIBUSINESS :Biopesticides and the benefits in agribusiness. Biopesticides and the benefits in agribusiness. Greenhouse growers are using biopesticides in conjunction with commercially purchased natural enemies as a part of their integrated pest management (IPM) programs. Biopesticides are pesticides derived from natural materials, including animals, plants, fungi and microbes. The Biopesticides and Pollution Prevention Division of the Environmental Protection Agency, which registers biopesticides in the U.S., classifies biopesticides into three categories: biochemical, microbials and plant-incorporated protectants. AGRIBUSINESS :Biopesticides and the benefits in agribusiness. Biopesticides offer numerous advantages to growers, including lower risk to employees, minimal (or no) re-entry and pre-harvest intervals, and compatibility with biocontrol programs thus promoting agribusiness. AGRIBUSINESS :Biopesticides and the benefits in agribusiness. Biochemicals are derived from naturally occurring substances such as plant extracts. This includes insect repellants, insect attractants and repellants, pheromones, and non-pest management class—plant growth regulators. Examples 1 )Azadirachtin (broad-spectrum insecticide). 2) Capsaicin (compound from chili peppers) (broad-spectrum insecticide, nematicide and fungicide). 3) Clove, rosemary and peppermint oil (broad-spectrum fungicide). Microbials are products containing micro-organisms or their fermentation by-products. Examples 1)The bacterium Bacillus thuringiensis for use against caterpillars. 2)The fungus Beauveria bassiana for use against whiteflies, aphids and thrips. Plant-incorporated protectants are pesticidal substances produced by plants as a result of genetic manipulation. There are no plant-incorporated protectant compounds registered for use in greenhouses. source.

Elephantiasis.

Elephantiasis also called lymphatic filariasis causes extreme swelling in the arms and legs. The disease is caused by the filarial worm, which impairs the lymphatic system and can lead to the abnormal enlargement of body parts, causing pain, severe disability and social stigma. The infection occurs when filarial parasites are transmitted to humans when mosquitoes bites causing hidden damage to the lymphatic system. The painful and profoundly disfiguring visible manifestations of the disease, lymphoedema, elephantiasis and scrotal swelling occur later in life and can lead to permanent disability. These patients are not only physically disabled, but suffer mental, social and financial losses contributing to stigma and poverty. Elephantiasis is caused by several different types of parasitic worms, including Wuchereria bancrofti, Brugia malayi, and B. timori, with Wuchereria bancrofti responsible for 90% of cases and transmitted by the female culex or aedes mosquito. The B. malayi and B.timori responsible for about 10% of cases are usually transmitted by female anopheles or mansonia mosquito. When an infected female mosquito bites a person, she may inject the worm larvae into the bloodstream. The worm larvae reproduce and spread throughout the bloodstream, where they can live for many years. The parasites accumulate in the blood vessels and restrict circulation and cause fluid to build up in surrounding tissues. The common symptoms are 1) fever 2)swelling of arm,legs. 3)swollen testicles(hydrocele) more
