Mechanical pulping is typically used for softwood.One of the advantages of mechanical pulping is it has a great yield around 95% from dry weight of input material,however it requires great energy, because the resulted paper are opaque, weaker and easily to discoloration with the exposure to the light.The mechanical pulps are more weaker than the chemical pulps, however it ia more cheaper to produce (about 50% of the costs of chemical pulp). Moreover, they gives the yield with the ranging of 85–95%24

1. Lung disease is the fourth leading cause of death in the United States. Technically any disease or disorder in which lung function is impaired is considered a lung disease. Some common respiratory diseases are Bronchitis, asthma, allergies, and hay fever. First, bronchitis is is an inflammation of the lining of the bronchial tubes, and less air is able to flow into the lungs, and mucus begins to form. This disease is usually come the environment, such as inhaling certain chemicals, cigarette smoke

During the synthesis, the first two steps are using SOCl2 (Thionyl chloride) and Na2SO3 (Sodium sulfite). Thionyl chloride is a reagent of the reaction of alcohols that replaces the alcohol with chlorine. Then, the chlorine becomes a leaving group, and the sodium sulfite reacts as a substitution. When the 3-aminopropane-1-sulfonic acid is made, this is treated with calcium hydroxide and acetic acid. Calcium hydroxide, which is a strong

expelled blue litmus paper was held above the conical flask on the hot bath and the litmus paper did not turn red. This was an indication that all of the sulfur dioxide had been expelled. The production of the sulfur dioxide was produced from the sodium sulfite being oxidised to sulfate, and the subsequent protonation to produce sulforous acid, which then became sulfur dioxide. The equation below illustrates the above method to produce sulfur

Introduction The history of mankind is intricately woven with the planet we live on, but is perhaps even more dependent upon micro organisms. While people often think that micro organisms are “scary” and “cause sickness,” there are several of these beneficial organisms that are more common than the “common cold.” Saccharomycetes Cerevisiae is one of these organisms and has been in use by humans for millennia. The evolution of this micro organic life form has been highly guided by the hand of humanity

John you must know what the effects are if you're not sure, pros & cons. In “What’s Formaldehyde & Antifreeze Doing in Your Skin?” there are many chemicals in today's tattoos. Such as unknown conglomeration of metallic salts (oxides, sulphides, selenides), organic dyes or plastics suspended in a carrier solution for consistency of application. Even the colorants are bad, close to forty percent of these organic colorants are used in permanent tattoos in Europe & are not even approved for use on the

addition to common triggers, food-triggers asthma affect in 6%-8% of asthmatic children but less than 2% of asthmatic adults. Often the triggers is sulfites, sulfite additives or a food allergen such as milk, eggs, peanuts, tree nuts, soy, wheat, fish or shellfish. Dr. Ron Simon of Scripps Clinic and Research Foundation in La Jolla, CA, stated, "sulfites in or added to food can cause potentially life-threatening reactions for asthmatics ("Medical Information", 1998)."

Food Preservatives: What the Health At forty-seven years old finding out she had cancer was terrifying, especially when chemotherapy was making Suzanne feel even worse. After feeling very tired, weak, and not being able to eat much, she decided she did not want to go through chemo-therapy anymore and tried a diet that a friend had told her about. This diet consisted of cutting out red meat, eggs, bread, cereal, and reducing dairy intake to one serving per week. This meant that on a daily basis

with GERD should avoid food and drink within 3 hours of bedtime, elevate the head of the bed, and eat smaller meals. [93] The most common triggers include allergens, smoke (tobacco and other), air pollution, non selective beta-blockers, and sulfite-containing foods. [94] Cigarette smoking and (passive smoke) may reduce the effectiveness of medications such as corticosteroids.[95] Laws that limit smoking decrease the number of people hospitalized for asthma.[96] Dust mite control measures

These days, most of us tend to take electricity for granted. If one were to be asked where it comes from, you would most likely get responses from all over, with a common response being, “Out of the sockets in the wall!” In this paper I will be giving a very brief overview of how electricity is produced, specifically from coal. Generating electricity requires a fuel source, and the fuel source for both EKP and DP&L is coal. About 60% of the electricity nationwide is produced by using coal.
