Toxic Chemicals from Peeing in the Pool

Lets face it. Its not just babies who pee in the pool! Is that guy on the other side of the pool trying to look cool or is he concentrating on a little public urination? You dont know, because there isnt a chemical you can put in the pool as a urine indicator that wouldnt be toxic or respond to a whole host of other fluids. The Water Quality and Health Council conducted a survey that revealed one in five Americans admit to urinating in the pool. So, unless that pool was filled an hour ago, youre swimming in pee. But, urine doesnt just sit there in the water or harmlessly disperse. It reacts with chemical treatments in the water. For the same reason you dont want to rinse out a really nasty kitty litter box with bleach, you might not want to inhale too deeply in a pool full of people. The chemical reactions form two particularly nasty compounds: cyanogen chloride (CNCl) and trichloramine (NCl3). In high concentrations, these are chemical warfare agents. In the minute quantities produced in a pool, you wont die, but youre not doing your lungs any favors, not to mention your nervous and circulatory systems. Chlorine treatments, in particular, react with uric acid from urine to form toxic chemicals. The pool treatments themselves often aggravate respiratory and other health problems, since chlorine is (you guessed it) a toxic chemical agent. Its really not something to worry about, as researchers have found levels of the chemicals are lower than the World Health Organization (WHO) limits for public drinking water. However, if it bothers you, you have a few options. Swim in an outdoor pool rather than an indoor one, so vapors become diluted in the air rather than trapped in an enclosed space. Switch to a different pool disinfection method. Or, you can build your very own private pool and resist the urge to pee in it.

Alzheimer s A Type Of Dementia - 1660 Words

Introduction: Alzheimer’s is a type of dementia that causes complications with memory, thinking, and behavior. Long before any signs of memory loss, there a microscopic changes occurring in the brain, altering its functionality (Alzheimer s Association Organization, 2016). The brain has billions of nerve cells that work together, and when one portion of the brains neurons are malfunctioning it leads to breakdowns in other parts of the brain. The two most noted abnormal structures that are suspected to damage and kill neurons in the brain in patients with Alzheimer’s are plaques and tangles. Plaques are deposits of a proteins fragment called beta-amyloid that build up in the spaces between nerve cells; and tangles are twisted fibers of another protein called tau that build up inside cells (Alzheimer s Association Organization, 2016). There are many different types of dementia, but Alzheimer’s is the most common, accounting for 60-80% of dementia cases in America (Alzheimer s Association Organization, 2016). There are three types of Alzheimer’s, Early-onset Alzheimer’s, when people younger than 65 years old are diagnosed with the disease, typically around their 40’s or 50’s and is very rare, less than 10% of all people with Alzheimer’s have early-onset; Late-onset Alzheimer’s which is what most people are familiar with, and is when someone is diagnosed with the disease after the age of 65; and lastly, Familial Alzheimer’s disease which is a form that doctors know forShow MoreRelatedAlzheimer s Disease : A Type Of Dementia1154 Words   |  5 Pages Alzheimer’s disease is a type of dementia that causes problems with your memory and behavior.

Racial Discrimination and Injustice in the South Essay

Racial Discrimination and Injustice in the South As in To Kill A Mockingbird by Harper Lee there was a great deal of injustice in the south in the early 1900s and before. Things only seemed to get worse when the depression. â€Å"We were always poor, but the Depression was definitely worse†(Johnson). The fiction in the book could very well be based on real facts of the way the blacks were treated in the past. Blacks of the time could not get a fair chance in real life or in the book. For that reason Tom Robinson could never have gotten a fair trial in Alabama in the 1930’s. The most significant event that led up to the way that blacks of the time were treated was the Civil War. Even though it was not solely fought to end slavery†¦show more content†¦Ã¢â‚¬Å"A Mississippi lynch mob of 2,000 burns an accused black rapist alive, a coroner’s jury returns a verdict of death ‘due to unknown causes,’ and Mississippi governor Theodore G. Bilbo says the state has ‘neither the time nor the money’ to go in to the matter† (Trager 792). The government in the South was not willing to give the blacks a break. The formation of the Ku Klux Klan after the Civil War was to be part of the cause of the troubles that the blacks had in later years. â€Å"The original Ku Klux Klan had been founded as little more than a friendly club in 1866. The founders, a group of bored Confederate troopers, felt the need for a club to recapture some wartime comradeship and excitement† (Taylor 1142). This original intent did not last long. Soon they took on their self-appointed duty of keeping white supremacy. This idea of white supremacy even extended against Jews, Catholics, and foreigners. The Klan would burn crosses in the yards of blacks and other people that were believed to sympathize with the black race. The Klan got so powerful that they decided that they should become political. Many officials in high-ranking government jobs were either Klansmen or supported by the Klan. They held offices in the north as well as the South.

Interface Usability of a Flower Shop App

Question: Discuss about the Interface Usability of a Flower Shop App. Answer: Overview of the Project The flower shop named Flowerish has planned to develop a mobile app. The shop sells flowers, bouquets and related services to the individual and corporate customers. Even though the shop has a website but it does not help in increasing the volume of the business. Therefore it decided to develop a mobile app and launch it in the market to attract the new customers and increase the volume of the business by competing with the rivals in the market. The mobile app that is intended to develop for the flower shop Flowerish will help the shop to have its online presence to a higher level. By introducing this new app, the shop tries to fill the gap between the modern day customer demands and the supply from the shops (Dunford et al., 2014). As the ubiquity of the smart devices or say smart phones are getting increased day by day, therefore the development and the introduction of the mobile app is going to help both the shop by increasing the amount of revenue from the business (de Andrade et al., 2015). Moreover, the customers can order and get their flower just by booking it on the app on real time basis. Vision The website of the shop does not provide any information about products or services from the flower shop. Therefore, by introducing the app for its business the vision of the flower shop is to provide information about the availability of the flowers in the different occasions like the mothers day, fathers day, valentines day etc . According to a survey it is estimated that, the number of smart phone users in Australia in 2017 will be almost 19.4 million (Xanthopoulos Xinogalos, 2013). Therefore the app will help the shop to have a successful penetration in the niche markets. Outcomes The outcome of this project is an app that will display and provide information about the bestselling flowers and services from the shop. The interface of the app will help the customer to choose the flowers from a wide variety. Moreover, the flowers that are not in the stocks are going to be placed in the special order category. At the same time the staffs will be notified by the app whenever a booking is done so that the products can be packaged and delivered on time (de Andrade et al., 2015). These features are going to help the shop in competing with the rivals in the business. Scope The project scope includes the development of the app according to the client (in this case the Flowerish). The scope of the project includes the configuration and development of the mobile app. Moreover to manage the content and features, publishing of the content on the app is also include (Xanthopoulos Xinogalos, 2013). In addition to that, the scope also can be extended to include the other beneficial areas like the use of the new marketing methods by using the social networking platforms (Abel et al., 2013). The financial impact of this project will be a little overhead for the flower shop. The reason behind the overhead is the fees of the consultants, the cost related to designing questionnaires and accreditation certificates for the app. The scope of the project does not include the day to day maintenance of the app. Customization of the existing specifications or services to meet the shops business needs is also excluded from the scope of this project. Objectives of Development The objective of the app development project is to provide an app to Flowerish. This app will help Flowerish to increase its business. The expected objectives of the project includes the following, a) To encourage the flower shop to reduce the operational and advertising cost and improve the business performance (Joorabchi, Mesbah Kruchten, 2013). b) To effectively manage the inventory management system of the shop. Moreover, it is expected that the successful completion and implementation of the project at the clients end will increase the business of the flower shop by 50%. Output The output of the project will be very beneficial for the flower shop as well as its customers. For the shop a) Flowerish will have a better online presence at the same time it can attract the potential customers who are using the smart phones (Abel et al., 2013). Unlike its website, the app will be updated and maintained periodically and on a regular basis. b) The features of the app will help the shop to enter a successful niche market. c) Customers can view, buy, comment and provide review on the products that are available on the shops app. d) The customers can chat with each other about the products (Magrath McCormick, 2015). Moreover by using the loyalty scheme the customer can have cheaper deals on the flowers by using the app. Target The target customers are mainly the tech-savvy people who use their smart phones or devices to do online shopping or transactions. In addition to that the older and disabled people who cannot travel to the shops can also book the products using the app. In addition to that, the target of the shop can be given by entering into a niche market by providing the discounted rates on the flowers, bouquets and services (Joorabchi, Mesbah Kruchten, 2013). At the same time the app will have a notification system that is going to notify the staffs of the shop whenever order is booked. Success Criteria The success criteria for the app development project depends on the user involvement in the development, clear and specified requirements from the client side (In this case the flower shop), proper planning of the development procedure. The users of the app must be satisfied with the design development methodology of the mobile app (Magrath McCormick, 2015). Moreover the, completion of the small milestones in the in the whole process, clear vision with objectives and the hardworking staffs are the main criterias for the successful completion of the app development project (Joorabchi, Mesbah Kruchten, 2013). Since the app is developed for a flower shop, that is going to help it to increase its business, therefore its important for the developers to clearly understand the client requirements to avoid any conflict at any phase of the development. On the other hand the hardworking staffs are helpful for the flower shop to increase the effectiveness of the app. Key Assumptions The new app of the flower shop system assumes that the individual is using the smart device or a smart phone running the Android OS version 4.4 or greater. The hardware specifications of the device should meet or exceed than the LG G5 model. Moreover, the appropriate extension needs to be installed in the device. The extensions like the Text to Speech and Speech to Text should be loaded on the smart phones (Heitktter, Hanschke Majchrzak, 2012). In addition to that, it is to be ensured that all the participants should abide by the guidelines according to the project development plan. The project development plan may change as per the new informations and issues are identified by the flower shop (Marcano Belisario et al., 2015). The failure in detecting the changes and drafting the deliverables according to the schedule will result in the project delays. References Abel, O., Shatunov, A., Jones, A. R., Andersen, P.
