Ethylene glycol

There are several methods by which industry converts purified ethylene gas into polyethylene; a commonly used one is by means of a fluidized reactor bed. Before ethylene is sent to the fluidized bed, it needs to be first compressed and heated, then metallic catalyst particles are used to keep polyethylene molecules stuck together (this is done when the ethylene enters the reactor). Lastly, polyethylene comes out of the reactor as granular powder, which is later

Ethylene Gas Ethylene gas is one of the by-products of respiration, and occurs naturally as produce ripens. It can have both positive and negative impacts upon your program. Ethylene is a natural gas made by some fruits and vegetables. Ethylene causes certain fruits and vegetables to ripen faster, which can lead to over-ripening and spoilage. For this reason, you want to be careful to keep ethylene-producing items away from ethylene-sensitive product and that your storage and display areas have

Plant hormones are specialized chemical substances produced by plants. They are the main internal factors controlling growth and development. Hormones are produced in one part of a plant and transported to others, where they are effective in very small amounts. Depending on the target tissue, a given hormone may have different effects. Plant hormones play an integral role in controlling the growth and development of plants. A plant hormone is generally described as an organic compound synthesized

Back in the 19th century bananas were not widely known. In fact, the western world hardly consumed the fruit, because of its exotic origin. The cultivation of banana is not easy. Bananas are one of the most highly perishable products that also need specific weather conditions in order to thrive. Indeed, bananas are only cropped in tropical regions, where temperature never falls under 13-14 degrees Celsius with high percentage of humidity and well-drained soil. Moreover, countries with tropical climate

of respiration of the fruit gives ATP (Adenosine triphosphate) need for the methionine cycle and can lead to induced ethylene production without high levels of intracellular methionine. SAM is a crucial methyl giver and relates to numerous aspects of cellular metabolism. Thus, the two steps involved in the synthesis of ethylene is the formation of ACC and its conversion into ethylene. The genes encoding ACS and ACO have therefore been studied more deeply than other enzymes in the pathway, although

When reading Banana by Dan Koeppel I felt that by reading this book I’d learn more about the banana and why we love it so much. When I started reading, I began to understand that there are more than one species of banana and that this little fruit migrated just like all humans did across the world. Koeppel states that the apple from the garden of Eden wasn’t really an apple at but a banana, he goes into reasons why it absolutely would be a banana and not an apple. He also travels to different

There are many kinds of foods for their choices. Fast food becomes a popular choice, and helps them solve their time issues. Eating fast food becomes a favorite habit that most people who are young and teenager really enjoy to taste. McDonald, Popeye, Burger King, and KFC are the most brand names in the world. I like fast

ingredients in E-juice are propylene glycol, glycerin, nicotine, and artificial flavorings. Nicotine free E-juice, somewhat of a good thing, contains 95% propylene glycol and glycerin. For those who don’t know what propylene glycol is, propylene glycol is the chemical used for anti-freeze ice pack. It is labeled as a “safe” toxin, but none the less still a toxin. Propylene glycol when ejected can affects the skin, kidneys and respiratory system (breathing). Propylene Glycol is also referred to as “PG” and

Electronic Cigarettes: the Lesser of Two Evils? In the past few decades extensive research has gone into studying the effects of cigarettes on air quality. Many carcinogens and particulate matter (PM) exist in the second-hand smoke. The results from these studies have led to anti-smoking campaigns across the country; consequently changing the cultural acceptance of smoking into a cultural taboo. Not only did smoking affect the health of the consumer but conventional cigarettes also spewed several
