...The city of Wichita has an important decision to make. This decision is vital to each and every person living in or around Wichita. It will affect many people and will adversely affect their health in many ways. Many people have been to a convenience store and purchased a bottle of water, or a restaurant where they ordered a glass of water but few people ever consider what’s in the water. If a customer were to order a glass of water at a restaurant they would expect a glass of clean unadulterated water. For example when you order a glass of tea, several questions are going to follow. “Sweet or Unsweet?”, “Would you like a lemon in your tea”. Almost each and every drink ordered at a restaurant would have a few basic questions with the exception of water. There is not a single question or modification that can or should be made to water. However, what if the waiter asked you, “Do you want some chemical in your water?” Many people would be shocked or even confused on how or what to answer. Still you have another group of people that would firmly say no, and those people may even wonder if they chose the right establishment to patronize. This is the decision that the city of Wichita is pondering. This decision is to decide whether or not to add the chemical, fluoride to the water supply. Fluoride is usually found naturally in low concentration in drinking water and foods. The concentration in seawater averages 1.3 parts per million (ppm). Fresh water supplies generally...

...people of varying age groups and occupations. The large majority however tend to be young singles and couples, in particular females aged between 14-35 years. Generally bottled water consumers can be described as being more health conscious, contemporary and socially aware. SO WHY DO PEOPLE DRINK BOTTLED WATER? YOU NEED IT Regardless of the seasons and the weather, your need for water remains the same. Remember that 95% of human blood is water. HEALTHY CONCIOUS LIVING In these health conscious days water makes a great contribution to overall hydration.It is fat and kilojoule free and a great thirst quencher, which makes it a great choice for the health conscious consumer. Many people wish to get back to basics and drink something that is refreshing and pure. Some people also wish to avoid certain chemicals used in the treatment of public water supplies, such as chlorine and fluoride, and are therefore turning to the chemical free alternative. CONVENIENCE With the development of more widespread leisure and activities and the expansion of travel, for business and pleasure, consumers are increasingly turning to the convenience of bottled water for their refreshment. TASTE One of the main reasons why people buy bottle water is its taste! With the variation in tastes of the different local water supplies across the country, more people prefer the consistent refreshing taste of bottled water. MORE FACTS ON BOTTLED WATER......

Too old toothbrushes are also not gentle on gums and harbour a lot of bacteria. If you are type that forgets to buy a new tooth brush, get yourself the one that changes colour when it’s time to buy a new one. III. Use Of Fluoride Toothpaste Fluoride toothpaste is the best for removing plaque and strengthening enamel. When brushing, care should be taken not to ingest the paste. Too much chloride ingestion can cause serious health issues; a reason why it should not be used by children not over 3 years. Fluoride toothpaste solves a wide variety of dental problems including diseases e.g. Gingivitis. It is also recommended for sensitive teeth and gums and stained teeth. Since they are available in a wide range of variety, it is important to seek advice or recommendation from your dentist about the one that will work best for you. IV.

...toothbrush effectively and without damaging the gums. Aggressive tooth-brushing can wear down the enamel and affect the gums. c) Communicate to students that they will need to demonstrate the right way to brush. d) Discuss ways to apply fluoride such as by drinking fluoridated water, by applying fluoride gel, and of course by using fluoride toothpaste. How to Brush: 1. Take a soft or medium toothbrush and hold it firmly at 45-degree angle in your fingertips – not in the palm (Hendrick, 2009). The name of this method is “Bass.” 2. Apply a pea-sized amount of toothpaste with fluoride, about the size of the tip of the baby finger. 3. Brush gently in a circular motion cleaning the front and back side of each tooth. According to Van B. Hayward, DMD, professor in the department of oral rehabilitation in the School of Dentistry at the Medical College of Georgia, “When the protective layer of enamel erodes or gum lines recede, a softer tissue in your teeth called dentin can be left exposed.” Since dentin is connected to the tooth’s inner nerve center, when it becomes exposed, the nerve center can become unprotected and sensitive causing pain (Hendrick, 2009). To prevent caries and prevent gum damage, it is important to practice good oral hygiene, which means brushing properly at least twice a day for two or three minutes and flossing regularly. Flossing Flossing is a skill that can help us...

...SCH4U – The Chemistry of Covalent Bonding Date_____________________ Orbital Hybridization One of the most influential chemistry books ever written was The Nature of the Chemical Bond by Linus Pauling (1901-1994). Published in 1939, Pauling was awarded the Nobel Prize in 1954. Pauling received a second Nobel Prize for peace in 1962. Pauling made tremendous contributions to the field of chemistry, and was an outspoken activist against war and nuclear weapons. If you consider the energy level diagram for carbon it presents a problem to the VB theory. If bonds are formed between orbitals that contain unpaired electrons, how many bonds does it appear carbon can form? | | 2 | | 1 | | Since Carbon only has 4 different 4 valence electrons, according to the Aufbau principle, the 2s orbital is filled first, and then the 2p sub shell has 2 orbitals with unpaired electrons. This suggests that Carbon can only form 2 bonds. However Carbon is clearly able to form 4 bonds, as evidenced by any carbon compound (e.g. methane, CH4). Linus Pauling suggested that carbon is able to create four unpaired orbitals by promoting one electron from the 2s orbital to the empty 2pz orbital. This hybridizes the one 2s and three 2p orbitals together. This configuration is called ‘sp3’. Like s and p orbitals, the ‘shape’ of sp3 orbitals can be defined by a probability density map of electron location around the nucleus. The shape of a sp3 orbital looks like this: Since carbon...

...brush your teeth properly or what can happen if you don’t? How are you supposed to know if you aren’t taught? That is why I will be discussing what materials you need to have for good dental hygiene, what the proper technique is to make sure your teeth are clean, and the harmful effects of not keeping your teeth clean. The first step to good dental hygiene is making sure you have the right materials. A toothbrush is the most important tool you will need. When picking out a toothbrush, you should look to see if the bristles are soft, hard, or maybe in-between. If your teeth are sensitive, you should pick the soft bristles because you could damage your gums if they are too rough. You also need to check to see if your bristles start to fray. If your bristles start to fray that means your toothbrush is old and no longer effective and it’s time to get a new one. Another material you need is floss; floss is just as important as a toothbrush because it gets all the leftover food out from in between your teeth that can cause bad breath or cavities. Toothbrushes are made for the flat surfaces of your teeth and floss is used to get the extra buildup from in-between your teeth. The last important tool needed is toothpaste; without toothpaste you wouldn’t be able to clean your teeth. When looking for toothpaste you should check to see if it has fluoride in it because fluoride is an extra liquid that stays on your teeth all night and helps prevent cavities. The second step is to make sure...

...Colgate Max Fresh 1. After P&G lunched Crest, fluoride toothpaste on the U.S market, CP had some problems with distribution therapeutic products, because of P&G`s patent on this technology. As a result, CP hat to concede this market to Crest. During the next period of time Colgate was focused on developing its business internationally and quickly got a success in the most global markets. After 1990s all producers could use fluoride in their products. In 1997 CP launched Colgate Total as a premium product with a 12 hours teeth protection. This product was very popular on the market. But CP wasn`t going to stop improving their product. In late 2002 a new toothpaste formula was invented. This product was launched as Colgate Max Fresh. This product was really unique; it utilized its patented technology of dissolvable mini breath strips as a point of differentiation. CMF provided protection against a full range of oral health problems and it was a convenient alternative to traditional mouth fresheners. Cavity/fluoride protection was a key benefit for the customers, but Colgate presented their product firstly for freshening a breath and secondly for whitening. The importance of whitening segment was growing, CP considered it can be the “the price of entry” with any premium – priced product launch. The technology of strips was very strong on the market, but because of high manufacturing costs on the emerging markets, CP should have created cost-optimized formula. The next...

...Practicing Oral Health i. Why did you choose this health behavior? The main reason I choose this behavior is because I think taking care of your mouth is the upmost important thing to do as it can affect other parts of your body. I have always taken care of my teeth to avoid the dentist as much as possible and keep cavities at a bare minimum. Oral hygiene is important to keep up with because nobody wants to have rotten teeth. We all want a perfect smile without stained or cavity filled teeth so why not take care of them right the first time so never have to get false teeth. For me, oral hygiene is one of the first things I ever think of and I hope other people feel the same so they can have long lasting teeth and avoid the dangerous cancers and gum diseases. The potential epidemiology of oral hygiene can always lead to a disaster of things by simply ignoring it or putting things in a mouth that causes negative health issues. The epidemiology of oral health is influenced by age, sex, origin which is associated with oral cancer risk and established risk factors including alcohol and tobacco use, for example. Additionally, possible associations between oral cancer risk and oral hygiene, diet, nutritional status, and sexual behavior as well as the influence of genetic factors on oral cancer risk are considered (NIDCR Home). Oral health also has an effect on other persistent diseases. Because of the failure to tackle social and material determinants and incorporate oral...

...When food particles and residue gets stuck on their teeth, it turns to tarter. Small amounts of tarter here and there isn't going to cause any serious problems, but over time it can and will lead to tooth decay, gingivitis, tooth loss and other forms of gum disease. You can think of a toothbrush as your weapon in the fight against tarter and tooth decay. Some owners may simply try to brush their Chihuahua's teeth with an old toothbrush and regular toothpaste, but this isn't recommended. Chihuahuas, like most dogs, will probably try to eat anything you put in their mouth. Regular toothpaste that we use in our mouths contains fluoride, which can be harmful if swallowed. Even small amounts of fluoride can make a Chihuahua sick to their stomach. So, how are you supposed to brush your Chihuahua's teeth? There are actually toothbrushes and toothpaste designed specifically for dogs. The toothbrushes come in a wide range of sizes designed to fit all breeds of dogs. Some of them are even sleeve-like pieces that fit over your finger with stubbles on one side. Canine toothpaste is made with delicate ingredients that are completely safe for small dogs. In addition, they come in a variety of flavors so your Chihuahua will likely enjoy getting their teeth brushes. You can find canine toothpaste available in beef, chicken, salmon and malt...

...EXPERIMENT 1 DETERMINATION OF DISSOLVED OXYGEN IN WATER INTRODUCTION The dissolved oxygen content is an important index when considering its suitability for town supply. A good clean potable water will give dissolved oxygen value close to the theoretical value for the saturated solution of oxygen in water. When there is pollution from organic matter and other trade effluents, the dissolved oxygen is up in various biochemical oxidation processes and its is only slowly replaced through surface absorption. Such water will give a low dissolved oxygen content until oxidation is completed. Adequate dissolved oxygen is necessary for the life of fish and other aquatic organisms. The methods described below for the determination of oxygen in water is based on that devised by Winkler. When manganese hydroxide is precipitated in the water sample it is quickly oxidized to higher hydrated oxides (probably in the four valent state) by the dissolve oxygen. Iodine, equivalent to the dissolved oxygen content, is then liberated on acidification in the presence of iodine, and it may be titrated with standard thio‐sulphate. INTERFERENCES AND PRE – TREATMENT Most oxidising and reducing substances e.g dissolved organic substances, nitrite ions, higher‐valency manganese compounds, active chlorine, sulphide and sulphite ions, iron (II) and irons interfere. The influence of the dissolved organic substances can be excluded by conversion of the manganese hydroxides...
