Prepare a on one form of soil degradation, its impact, methods that are being used to reduce or reverse its impac - Research Paper Example The paper also presents various methods that are being used to reduce or reverse its impact. The relevance of soil erosion to the sustainable use of soil has been discussed. Soil Erosion Soil erosion is a phenomenon that has been taking place for many years. Loose soil on the earth surface is moved by water and wind especially where the ground is bare. As the soil is formed, it is moved away to a different place if it is not covered or held tight by vegetation (Toy et al 2002). Intense human activity has caused soil in the recent past to be moved at a higher rate than its formation. Some activities such as overgrazing and inappropriate farming practices have increased the vulnerability of soil to erosion. Soil that is left bare is carried away by strong wind or rainfall and deposited in rivers and water masses (Cox and Ashley 2000). Rain splash is among the causes of soil erosion whereby very strong rain drops fall on bare soil detaching and moving it for a short distance. The effect s of splash erosion are usually in-situ since the soil is only moved over a minimal distance. Moreover, the rain must fall with significant intensity for erosion to take place. The soil is re-distributed on the surface unless if the area is sloping. Rill erosion may occur when the soil is moved along channels down slope. When the intensity of rainfall is high, the channels may enlarge to form gullies. Gulley erosion is more pronounced in many parts of the world and is associated with mass movement of soil (Bathgate and Pannell 2002). Generally, when the rain falls on soil, a substantial amount of water is absorbed until the soil is saturated. It takes time for the water to infiltrate and therefore the more time the water remains on the soil surface the greater the possibility of absorption. Soil erosion is mainly attributed to overland flow, which is the water that does not infiltrate in to the soil. This occurs mostly when the rainfall is sudden and with high intensity giving littl e time for absorption. Excess runoff is moved down slope by gravity and as rills converge at the bottom of the slope, larger gullies are formed and the overall result is high intensity of erosion and huge soil deposits down slope (Boardman 2006). Wind is also a significant cause of soil erosion especially in semi-arid areas. It redistributes soil and may also move it over a long distance. Soil with detached individual particles through human and animal activities is susceptible to wind erosion. Soil may as well move down slope through tillage (Troeh, 2003). This is usually attributed to wrong methods of plowing, such as contour farming down slope. Apart from moving the soil, tillage creates weakness in soil layers making them susceptible to other forms of erosion. Soil erosion may take place in a gradual and unnoticeable manner eventually causing significant impacts on the soil. In most cases, people tend to control soil erosion once it has occurred rather than putting preventive me asures in place to avoid its occurrence (Abel 2001). Impacts of Soil Erosion Soil erosion is a major environmental problem in the current day since it does not only affect the productivity of land in-situ but also affects the environment ex-situ where the soil is deposited. It has been a significant contributor of flash floods in areas down stream as soil layers accumulate in river channels thereby raising the riverbeds. The result has been mass displacement of populations and damage of crops (Vaclav 2000). On the other hand, soil erosion

Globel health presentation Essay Example | Topics and Well Written Essays - 500 words

Globel health presentation - Essay Example In 1978, the Alma-Ata declaration developed a global policy for health, which was to be realized by the year 2000. In this global policy, a universal primary health care system based on acceptable and practical methods was adopted. This was to involve the people and be affordable in different countries. This was adopted by most countries, except some capitalistic countries. In developing countries, this was faced with a number of obstacles, including political instability, poor economy, and emerging diseases. WHO is a major player in implementing the Alma Ata declaration. The development of the Millennium Development Goals (MDGs) helped in propagation of global policy. Today, different studies show that a health system comprising primary care is likely to deliver better health care. However, it is impossible for one heath policy to apply to the whole world. This is because of the difficulty in formulating uniform health interventions, which target a great number of people and different key groups with varying risk factors. These also live in different environments. Maternal and child health are critical in the global policy. Cost-effective interventions were identified, but the evidence on how these could reach the vulnerable groups was not established. Generally, the Alma Ata declaration is an unfinished business. However, it has been influential in responding to dynamic health issues across the globe, and so is a potential for health developments. The World Health Organization has a global policy of improving the quality of health, developing healthy lifestyles for all people, alleviating health risks, and being responsive to the determinants of health involved. The WHO public policies of health are age-and gender-sensitive, which will facilitate the empowerment of communities, self-care, and health protection, while cooperating with its different partners. On biological weapons, the

MS project capstone - Thesis Proposal Example In cases where platforms are found through operating systems, a limitation is also seen in the number of functionalities that the monitoring systems can perform. A new application is therefore recommended with a multi-purpose functionality that combines aesthetic power with performance. This application will give a visual display of all that it taking place within the networking process including upload and download speeds, new clients that join the network, rate of highest and lowest value fluctuations and so on. Topic Statement Not long ago, most network system administrators were very limited in terms of the available operating systems with which they could use to process their system applications. This is because there was so much monopoly in the operating system market (Fielding, Teutsch and Koh, 2012). Today, the introduction of some new and somewhat advanced forms of operating systems such as the android operating system has eradicated this deficiency. But as much as the avail ability of new operating systems comes with their own advantages and merits, there are some key challenges that network system administrators have to face. A typical example of this is the influx of websites, servers, routers, surveillance systems and Wi-Fi management systems, all of which perfectly fit into the processing and use of a single network operation. In order to ensure that the number of applications possible to run on a single network does not become a burden, network system administrators need to have troubleshooting tools that can monitor the periodic activities that take place within these websites, servers, routers, surveillance systems, and Wi-Fi management applications. Even though there are more of such new operating systems that may effectively serve the purposes of network system administrators, there is particular emphasis on the android operating system, which comes with a number of android applications for use by network system administrators. Significance Th e significance section of the project capstone touches on what the researcher wants to show for the entire project at the end of the day; as well as the specific activities that will be needed to perform to make the achievement of this possible. In effect, the aim is a generalized goal whiles the objectives are a set of activities that needs to be performed to achieve the aim. Consequently, the aim of the proposed study is to design an application. To successfully achieve this, the following specific objectives must be met. 1 To identify a networking system that works best for android devices 2 To develop an application that monitors the upload and down speed per second. 3 To develop an application that can monitor the number of connection users at any present time on the network. 4 To create a network monitoring system that looks specifically at the rate of network running. 5 To create a simplified version of network monitor that works in the forms of a dashboard for easy visibilit y and accessibility. 6 To build a Wi-Fi network data traffic that will be responsible for monitoring the capabilities of network to be sure that these networks perform to their maximum capacities. 7 To have a warning system in place against network data traffic. Proposed Solution and Deliverable The researcher shall embark on a mixed research approac

CIS 375 Week 2 Assingment Assignment Example | Topics and Well Written Essays - 1000 words

CIS 375 Week 2 Assingment - Assignment Example The section below provides a comparison between the metaphors used in the two interfaces. Metaphors are a basis for the interaction and communication between the user and the computer. According to Carroll, Mack, & Kellogg (2007), applications utilizing menu driven screen have metaphors such as mouse pointers and cursors to indicate the motion of the mouse on the screen. This metaphor has been replaced all together on the multi-touch screen interface. The mouse driven interfaces are operated by dragging the cursor on the screen and effecting commands by clicking. Underling concepts of the application are presented in form of icons for a user to understand. Both the mouse driven and multi-touch screens use icons to represent underlying application concepts (Carroll et al, 2007). For instance the recycle bin is used to represent deleted items. Mouse driven screen interface uses the desktop metaphor which is a unifying concept that helps users to easily use a computer. The desktop metaphor treats the computer monitor as the user’s interaction point. Here, objects such as documents, files, folders and other accessories are placed. On the other hand the multi-touch screens use the home metaphor where all applications can be accessed by the user. In other applications that use both the mouse driven and multi touch screens both the home screen and the desktop metaphors can be used (Carroll et al, 2007). Multi-touch screens allow moving layered views to allow the user to view content beneath them; the screen also uses swiping as a way of viewing different windows. Additionally, the interface uses the dragging, flicking and swiping objects on the screen. This is common when playing games and performing other basic tasks (Carroll et al, 2007). The mouse driven screen will perform this tasks using the minimizing and maximizing option on the window. This interface also utilizes the dragging metaphor for movement of objects on

Drama Essay Example | Topics and Well Written Essays - 750 words

Drama - Essay Example In this paper I will argue how on many occasions in Oedipus the King, Oedipus and other prominent characters make such comments which emphasize varying levels of power each of them is awarded with. Facts and discussion presented in this essay are basically meant to illuminate the reality of the claim that though Oedipus is presented as the absolute ruler of the city of Thebes by Sophocles, he is actually overtaken or even thwarted at some points in moments of hotheadedness by other influential characters who in a discreet way have more polished sociopolitical and spiritual understanding. It is evident that Oedipus has at least sufficiently more power than his wife (or mother) Jocasta because no amount of pleading or persuasion from her inflicts any effect on him and he maintains an inexorable, persistent, and adamant attitude about hearing the truth from Tiresias who is the oracle of God Apollo. Jocasta does not have enough power which could make her stand up resolutely against Oedip us in order to stop him from going to Tiresias upon listening from Creon that the plague existed in the city because the murderer of Laius remained in the city. Their spiritual ideologies also set in contrast to each other because unlike Oedipus who is moved after being condemned by Tiresias, Jocasta bluntly expresses that he should not worry in the least because all prophets are flawed or phony which is something very controversial or notorious to be said about the spiritual or religious matters for those times. Also, the political power that Oedipus has surpasses that of Jocasta’s because even though she tries to talk him into not punishing Creon on any account, he refuses to second guess his decisions and goes on to banish his royal colleague (Creon) from Thebes because he says, â€Å"my one-time friend Creon attacks me secretly for wealth and power† (li. 452, Bartel). The title of king and the associated power is desired by Creon even more than Oedipus and he comes across as a shrewder politician with more reasonable social vision than King Oedipus who is often hotheaded, frenzied, and exposed unlike the secretive, calm, and manipulative attitude of Creon. But, that does not mean that Oedipus does not get his share of miseries or defeats in the play only because is the sole ruler of the city who could not be intimidated by anyone else. Tiresias, for example, is one character who is not at all influenced or scared by the political power of Oedipus. When Oedipus accuses Tiresias that â€Å"you are blind in mind and ears/as well as in your eyes† (li. 370-5, Goldhill 219) after listening from him that the plague existed in the city because of himself, the oracle without considering the fact that he is in the presence of a king replies pointblank, â€Å"you are a poor wretch to pile upon me insults which everyone soon will heap upon you† (li. 370-5, Goldhill 219). He also fearlessly tells Oedipus that â€Å"although you are the rule r, we have equal power to speak. I am not a slave to you, but I serve Apollo. You insult my blindness, but you, who are not blind, cannot see your own suffering† (li. 410, Sophocles’ Oedipus Tyrannus). The powerful functions of the Chorus or Choragos are also very prominent in Oedipus Rex. The Chorus have sufficient power over Oedipus in that they try to contribute wisdom by telling him to stay clam like a smart ruler and stay away from seeking trouble. The Chorus have

Assignment Internal Cash Control Essay Example for Free

Assignment Internal Cash Control Essay The weaknesses in the internal control over cash disbursements are, there should be only one person in charge of writing the checks for each task, and there should be numbered checks for both people so that the funds spend can be tracked easier, the cabinets were the checks are stored should be two locked cabinets, one for each person who writes the checks. Memo: I would recommend that to have a better control over money paid and items purchased, that you start having numbered checks in two separate accounts, one account for the treasurer and one account for the purchasing agent. This method will make it easier for moth parties to avoid mistakes, and it will also be easier to verify money spent and received. P4-1A The internal control principles implemented by the Guard Dog Company are, numbered checks so that the company has a number trail to monitor cash dispersment. Each check must have approval from Jane Bell, and Dennis Kurt before a check can be issued, this is an establishment of responsibility to ensure that not just anyone ion the company can write checks. Checks must be signed by either Tom Kimball, the treasurer, or Karen Thews, the assistant treasurer. Before signing a check, the signer is expected to compare the amounts of the check with the amounts on the invoice, this is also a form of establishment of responsibility and both of these procedures are a use of documentation procedures. After signing a check, the signer stamps the invoice â€Å"paid† and inserts within the stamp, the date, check number, and amount of the check. The â€Å"paid† invoice is then sent to the accounting department for recording. By doing this it is a way of verifying company cash dispersment and documentation control. Blank checks are stored in a safe in the treasurer’s office. The combination to the safe is known by only the treasurer and assistant treasurer. By locking the checks in a safe it establishes responsibility for the checks, and uses a Physical, mechanical, and electronic controls to narrow down any check problems to one source. Each month the bank statement is reconciled with the bank balance per books by the assistant chief accountant. By doing this it establishes document control, this way any discrepancies in the amount paid can be verified. Indicate the weaknesses in internal accounting control in the handling of collections. The weaknesses in the handling of collections are the way the money is deposited, the way the checks are made out and the way the money is verified and deposited. P4-2A List the improvements in internal control procedures that you plan to make at the next meeting of the audit team for (1) the ushers, (2) the head usher, (3) the financial secretary, and (4) the finance committee. The improvements the ushers need to make is that after each offering they should individually count their own collected baskets and log there amount in an offering log book, so that there is less room for error in the next step. By handing all the baskets to the head usher without counting the money themselves, the head usher can offer any amount on his final deposit. The improvements the head usher needs to make is to make sure that each usher counts their baskets, and that the head usher counts all the baskets and checks for discrepancies to make sure that no one is pocketing any money. The head usher should also check the amount given to him/her against what is written in the offering log. Have a book to log the amount of money that is put into the safe so that it is logged in a way that can be verified by the committee, a note is not a safe method because it can be thrown out, by logging in a book it is easier to find were the discrepancies came from. The improvements the financial secretary should make is that he/she should have a list of what needs to be paid and make a log of the amounts that need paid and to make sure the receipts are logged along with whatever bills or services that needed to be paid that week. The financial secretary should also verify the amount of money in the safe against the log that is kept by the ushers. The financial committee should show a more detailed list of what expenditures are needed each month so that the financial secretary knows what is needed for payment that month. They should also be involved in verifying the churches income. To improve internal control the church should have a log for money received during offerings, they should tell the congregation to make the checks payable to the church or to the account holder that the checks are deposited into, because anyone can cash a check made out to â€Å"cash†. The church should also verify that any money not deposited from the offering was spent properly and not used for personal things. Include how a company could use the five basic principles of cash management to increase accuracy for a business. A company can increase the collection of receivables by offering incentives for quick payment from their customers. A company can delay the payment of liabilities and bills to close to the due date of the liability or bill, so that if any expenditure is needed before the due date they will not have spent the money too early. A company can keep inventory low on the merchandise that does not sell quickly, so that the company has money for the merchandise that is popular and selling fast. A company that wish to expand should wait until they have excess money in a slow season so that they can expand their business and have new locations open in time for their busy season. A company should invest money that is sitting idle into low risk companies’, the most common form of liquid investments is interest-paying U. S. government securities.

Experiment to Learn the Amount of Iron in Iron Tablets

Experiment to Learn the Amount of Iron in Iron Tablets GABRIELA CARUSO KANDIR 1.1 What is Topic area you are investigating in to: Prepare and standardize a potassium permanganate solution and use it to determine the amount of iron (II) in iron tablets What is your title: Analyze the actual amount of iron (II) present in a tablet of iron supplement What is your Aim: Demonstrate if iron supplements have the adequate levels of iron (II) by studying if the claims in supplement bottles are correct or not. 2.1, 2.2, 2.3 Objectives: Measure the amount of iron (II) in supplement tablets through performing a redox titration reaction 2.1, 2.2, 2.3 Extraneous variables (contaminants): Permanganate solutions tend to decompose with time, causing a change in concentration. To overcome this variable it is important to standardizing the KMnO4 solution. Sulfuric acid should always be in excess to avoid insoluble brown manganese oxide (MNO2) formation. Introduction and/or rationale: Iron is a mineral that is naturally present in many foods, added to some food products and available as a dietary supplement. Ion is an essential component of hemoglobin, an erythrocyte protein that transfers oxygen from the lungs to the tissues. As a component of myoglobin, it provides oxygen to muscles. Iron also supports the metabolism and is necessary for growth, development, normal cellular functioning, and synthesis of some hormones and connective tissues. In case of iron deficiency the human body cannot make enough healthy oxygen carrying red blood cells (erythrocyte), and a lack of those cells is called iron deficiency anemia. Without healthy red blood cells it is not possible to transport enough oxygen through the body, and without oxygen there is fatigue. Exhaustion can affect everything, from brain function to the ability of the immune system to fight infectious. The daily requirements for iron depends o age, gender and overall health. Starting at adolescence, a woman’s daily iron needs increases. Women need more iron because they lose blood each month during their period. That is why the NHS advices women from ages 19 to 50 to get 14.8 mg of iron each day, while men the same age need to ingest only 8 mg. For the same age group the United States department of health and the Heart and stroke foundation in Canada recommends a even higher daily intake of 18 mg of iron per day. Most women will ingest their daily iron needs through their normal meat and vegetables diet. Some groups, such as vegetarians, pregnant women, or those with higher blood loss (blood donations, heavy menstrual periods, stomach or intestine conditions among other examples) may need iron tablets supplementation on top of their regular diet. This is due either because of a decrease in ion intake (diet) or absorption or there is an increase in the iron needs (such as pregnancy or breast feeding for example). An iron deficiency and consequent anemia will lead to signs of short of breath, fast heartbeat, cold hands and feet, craving for strange substances such as dirt or clay, hair loss, sores at the corner of the mouth and sore tongue. As mentioned before, in some cases of iron deficiency eating a diet that is high in iron-rich foods such as fortified cereals, read meat, dried fruit and beans may not be enough to give the required needs, in this case a doctor may recommend iron supplement, but unlike some supplements, when the subject is iron, more is definitely not better. Adults shouldn’t take any more than 45 mg of iron a day unless they are being treated with iron under close medical supervision. 2.4 Analysis of source material: Oxidation-reduction (redox) reactions are one of many chemical reactions. Redox usually involves the transfer of electrons. Titration is the volumetric measurements of a solution of know concentration when it reacts completely with a measured volume or mass of another substance. The analysis of present iron in a supplement tablet can be done by a redox titration reaction. Iron (II) ions can be ionized to ion (III) ions by potassium permanganate in acidic solution. For the redox titration reaction one of the most commonly strong oxidizing agent is used, the potassium permanganate (KMnO4). Iron (II) will be oxidized to iron (III) and the potassium permanganate will be reduced to Manganese. MnO4+8H++5Fe2+à ¯Ã†â€™Ã‚  Mn2+4H2O+5Fe3+ As the Potassium permanganate doesn’t require an indicator to signal the end-point of the titration, it has a unique advantage among titrants. In an acidic condition the deep purple solution of manganite ions is reduced to a very pale pink solution of manganese ions. This solution is so pale as to appear colorless when dilute and, in practice, the marked difference in color between these two oxidation states is useful as an end-point for this redox reaction. The manganite ion accepts electrons and is reduced to colorless Mn 2+ ions according to the following half-equation: The potassium manganite solution is added from the burette to the solution of the reducing agent and is immediately decolorized. As soon as the reducing agent is used up, the next drop of potassium manganite solution is not decolorized therefore coloring the solution as a pale purple color. The end-point is the first appearance of this purple color. The acid used to provide H+ is dilute sulfuric acid. Risk assessment: Name of the Chemical Risk incurred How to reduce the severity of the risk Disposal/Spillage KMnO4 Not Hazardous Not Hazardous Not Hazardous 3M H2SO4 Risk 4 for irritating eyes and skin. Casing severe burns to eye, skin and body tissues. If well handled the risk is low. Wear Safety Glasses Keep out of reach of Children, Keep container in a ventilated place In case of contacted with skin or eyes, rinse immediately with water and seek medical advice If ingested wash out month, apply artificial respiration if needed, seek medical help Avoid contact of the acid with water. As any strong acid it may explode and or produce corrosive fumes in (fast) contact with water Wash down the sink with a large amount of water In case of Spillage, liquid can be absorbed using sand adsorbent. This should be transferred to a suitable container and disposed as contaminated waste Iron Supplement tablets Not Hazardous Not Hazardous Not Hazardous 2.1 List the equipment and chemicals/reagents you would use to undertake your experiment: Potassium Permanganate Burette and Clamp with white numbering Iron sample (Iron supplement tablets- 3 different samples) Appropriate glassware 3M sulfuric acid (H2SO4) Magnetic stirrer 3 100- 150 mL beakers 2.1 How you would carry out the experiment including the use of equipment and what chemicals/reagents you would use? preparation of the Iron tablet sample: Clear three 100-150 mL beakers with soap and water. Rinse with several small portions of distilled water Directly into each beaker, weigh approximately 0.5 grams of iron sample. Add 15 mL of distilled water to each sample and stir to dissolve the solid Add 8mL of 3M sulfuric acid, to each sample. This step is needed to provide the hydrogen ions, which are required for the reduction of the permanganate ion. Titration of the Iron sample Potassium Permanganate: Obtain approximately 55 mL of the standardized potassium permanganate solution (KMnO4), and record the exact concentration of the KMnO4 solution. Prepare the buret by cleaning, rinsing and filling with potassium permanganate solution. Record the initial volume reading to the nearest 0.01 mL Titrate each sample to the endpoint (first appearance of permanent- at leat 10 seconds-, pale pink color). Record the final buret reading The mass of iron in each sample can be determined from the volume of KMnO4 required to titrate. This is possible through determining the moles of KMnO4 used, and a balanced equation. 2.1 How will you collect and record the data: data will be collected from the 3 samples in a table with the initial and final volume of titrate. A note on the exact concentration of the KMnO4 solution will also be present in the results sheet. 2.1 How will you Analyze results: The mass present in each sample will be determine through the calculation of the concentration of a reagent from the titration results. Results will be compared with the claims from supplement bottles to verify if the amounts are similar or the claims are incorrect. 2.1 How will you present your data?: Data will be presented with tables showing the amount of iron (II) in the three samples followed by a comparing graph of the quantities found in the tests with the claims in the iron supplement bottles.
