...Advice to a patient regarding the use of eye patches following a corneal abrasion Mr X attended the Minor Injuries department with a queried foreign body in his right eye which had caused a slight (2mm) corneal abrasion and was causing him pain. This type of injury will normally self-heal rapidly within 24 to 72 hours, but usually be painful with symptomology aggravated by exposure to light, blinking and the injury rubbing against the inside of the eyelid (Wilson & Last, 2004). Mr X was experiencing moderate discomfort and enquired whether he should wear an eye patch following discharge. One of the “traditional” (Wilson & Last, 2004; Turner & Rabiu,2007) approaches to managing corneal abrasions of this type was to use an eye patch. Webb (1996) recommends patching the eye with two eye pads for a period of 24 hours for “patient preference”, as he noted that there was no benefit to the healing process. Purcell (2003) confirms Webb’s thoughts on patient preference adding that patching should always be carried out if the eye has been treated with anaesthetic drops to protect it whilst desensitised. Marsden (2002), supports the use of eye patches only to make the patient more comfortable and to offer a choice (patch or no patch), disagreeing with Purcell (2003) that patches should always be used with anaesthetic on the basis that the eye is desensitised for a short period of time and patching has no clinical benefits. Templeton and Wilson (1983) state that a firm pad and bandage...

...sprinkled on sidewalks and road ways to melt the ice. When salt hits water or ice it lowers the freezing point in an effect known as freezing point depression and melting it in the process. According to (greenergreengrass.com) salt can also affect the pH of soil and can create an unsuitable environment for grass and plants to grow. HYPOTHESIS: The grass that gets exposed to more salt will not grow as much as the grass that gets exposed to little or no salt. PREDICTION: If the grass is exposed to salt then it will not grow as fast as the grass that is not exposed to salt at all. CONTROLLED EXPERIMENTAL METHOD: Ten patches of grass (1ft x 1ft) will be tested. At the beginning of the experiment we will start with ten patches of grass all which are 1ft x 1ft, and two inches tall. Every other day for seven days I will salt eight of the ten patches of grass. Two patches of grass will be salted with three grams of salt, two...

...vulnerabilities of systems will reduce or eliminate the potential for exploitation and involve considerably less time and effort than responding after an exploitation has occurred. Patches are additional pieces of code developed to address problems (commonly called “bugs”) in software. Patches enable additional functionality or address security flaws within a program. Vulnerabilities are flaws that can be exploited by a malicious entity to gain greater access or privileges than it is authorized to have on a computer system. Not all vulnerabilities have related patches; thus, system administrators must not only be aware of applicable vulnerabilities and available patches, but also other methods of remediation (e.g., device or network configuration changes, employee training) that limit the exposure of systems to vulnerabilities. This document provides guidance on creating a security patch and vulnerability management program and testing the effectiveness of that program. The primary audience is security managers who are responsible for designing and implementing the program. However, this document also contains information useful to system administrators and operations personnel who are responsible for applying patches and deploying solutions (i.e., information related to testing patches and enterprise patching software). Timely patching of security issues is generally recognized as critical to maintaining the operational availability, confidentiality, and...

...as well as video steganography ie, by using patches. Image quilting is another technique which is used here in order to weave the texture images as well as for weaving the frames [3]. General idea behind both the technique is same but in video an extra step for video framing is also performed. 3. PROPOSED METHOD There are 3 main process in the transmitter side. They are: • Index Table Generation • Patch Composition Process • Message Oriented Texture Synthesis The first process is the index table generation is to produce an index table to record the position of the source patch set SP in the synthetic texture. The index table allows the source texture completely. Such a reversible embedding style reveals one of the major benefits proposed algorithm offers. Here first determine the width and height of the index table (Tpw×Tph). Given the parameters Tw and Th, which are the width and the height of the synthetic texture intend to synthesize the count of entries in this index table can be determined using equation (1) where TPn denotes the number of patches in the stego synthetic texture. For simplicity, chose appropriate parameters for Tw, Th, Pw, Ph, and Pd, so that the count of entries is an integer. As an example, if Tw × Th=488×488, Pw × Ph=48×48, and Pd=8, then can generate an index table (12×12) containing 144 entries. TPn=TPw×TPh[(Tw-Tp)(Pw-Pd)+1]×[(Th-Tp)(Ph-Pd)+1] (1) Equation (1) denotes the number of patches in the stego synthetic texture. When distribute...

...Being brought up knowing that these drugs are bad makes you have a preconceived thought about these pills. David Leonhardt in “The benefits of opioids” published by New York Times “About 100 million Americans — or nearly one out of every three — suffers from chronic pain. For a good number of them, the pain is severe.” ( #1) It was that many people were affected from this pain. Clearly Advil or any other lower type of medicine does not work for them otherwise they would just use it. However, if these drugs get banned these people will either suffer from this pain daily and become miserable, or they will turn to the streets. If these people turn to the streets for the illegal drugs they will either have to pay ridiciously amount for these pills,...

...color in patches on different areas of the body. The extent and rate of color loss is unpredictable and it also can affect a person of any sex and of any age. Vitiligo occurs when the cells that produce melanin die or stop working, and unfortunately there are no doctors that know why this happens. It can become stressful at times and may even cause some people to become insecure with the way they look, but this disease is not life threatening. Vitiligo affects approximately 1-2% of the population around the world and there are many different treatments that can be used to help restore the color of the skin or even out the skin tone. But results vary and can be unpredictable. The primary method...

...0-Day Patch Exposing Vendors (In)security Performance Stefan Frei, Bernhard Tellenbach, and Bernhard Plattner Computer Engineering and Networks Laboratory (TIK) Swiss Federal Institute of Technology, ETH Zurich {stefan.frei, tellenbach, plattner}@tik.ee.ethz.ch http://www.techzoom.net/risk/ Abstract. We measure and compare the performance of the vulnerability handling and patch development process of Microsoft and Apple to better understand the security ecosystem. We introduce the 0-day patch rate as a new metric; being the number of patches a vendor is able to release at the day of the public disclosure of a new vulnerability. Using this measure we can directly compare the security performance of Microsoft and Apple over the last 6 years. We find global and vendor specific trends and measure the effectiveness of the patch development process of two major software vendors over a long period. For both vendors we find that major software development projects (such as a new OS release or Service Pack) consumes resources at the cost of patch development. Our data does not support the common belief that software from Apple is inherently more secure than software from Microsoft. While the average number of unpatched vulnerabilities has stabilized for Microsoft, Apple has bypassed Microsoft and shows an increasing trend. We provided an insight into the vulnerability lifecycle and trends in the insecurity scene based on empirical data and analysis. To properly plan, assess, and justify...

...Optimal Foraging All animals face the problem of finding resources for growth, maintenance and reproduction. It is assumed that natural selection should tend to produce animals that are very efficient at propagating their genes, and hence at doing everything else, including finding food and mates. At some point in an animal’s life it may experience starvation, and prolonged starvation can lead to death. By natural selection, the animals that survive are able to pass their genes to the next generation, while the genes from animals that die are eliminated along with their unsuccessful foraging behaviour. Foraging (food seeking) in a patchy environment requires complex decisions, such as where to forage and for how long. To make these decisions animals should acquire information from the environment. The questions we may ask include: Should a predator eat only the most nutritious prey? What other factors should be taken into account in its choice of prey? To optimise a diet Different foods have different values. In order to optimise a diet, a forager must be able to distinguish between different food items and select the most profitable. This holds for all predators, insects, parasitoids, etc… Many studies have shown that foragers prefer the most profitable food, eg: the size of mussels preferred by crabs was calculated by being the most profitable. Mussels that are too small have a very low energy content while very large ones require a lot of effort (time and energy)...

...Have you ever seen people walking around with white patches all over there body? Do you ever wonder what condition or disease that person may have? Do we at times just these people and look down on them just because they look different? What is our reaction when we see a person walking on the street that has white patches all over them? Are we quick to judge, or do we simply look at it as they have a health problem and there's nothing wrong with that? Do some of us even know what those white patches on the skin may mean? Those white patches that we at times see in some people are a condition known as Vitiligo. Vitiligo is medically known for being an auto-immune disease. An auto-immune disease simply means that the person's own immune system attacks its own tissues and in some cases their organs. When a person has vitiligo, their melanocytes are destroyed or killed off and they start to get pigmentations (white patches) on different parts of their bodies. The parts of the body that may get pigmentations are: the hands, feet, face, the inside of the mouth, genitals, rectum, and in some cases the persons hair may turn white because of the vitiligo. In other cases of vitiligo, the mucous membranes (tissues that line the inside of the mouth and nose) and the retina (inner layer of the eyeball) can be affected. The cause of vitiligo is still unknown, but some scientists and doctors have developed a few theories about its origin. Some scientists and doctors...

...Psoriasis comprises red, scaly patches of skin, which usually have very well defined edges, appear covered by silvery flaky surface [1]. These patches, which are sometimes referred to as plaques, usually itch or feel sore. The redness is explained by impressive growth and dilation of superficial blood vessels [2]. They most often occur on the elbows, knees, other parts of legs, scalp, lower back, face, palms, and soles of the feet, but they can occur on skin anywhere on the body [3]. The disease may also affect the fingernails, the toenails, and the soft tissues of the genitals and inside the mouth [4]. It is often symmetrical, affecting both sides of the body. Psoriasis is often so mild it is barely noticed by the affected person, but it can occasionally be so severe that the patient must be admitted to hospital for treatment. The disease occurs in all age groups, primarily affecting adults. The most common ages for psoriasis to first appear are in the late teens and in the 50s. It affects men and women equally, although in children, girls are more commonly affected than boys [5]. Being characterized as dermatological disease, psoriasis is a non- contagious lifelong skin disease and also not an outcome of poor hygiene. Unfortunately it is often overlooked or dismissed because it is not typically life threatening [6]. Depending on the variability in morphology, distribution, severity and cause, they are divided into different types. Some can occur independently or at the same...

...A inspirational woman known as Winnie Harlow once expressed, “If God wanted me to be black, I'd be black. If God wanted me to be white, I'd be white. But He chose for me to be both and original. So I guess that's the way I'm supposed to be.” Vitiligo is a somewhat common ailment in white patches of skin that have no pigment appear on the skin. Factors such as causes, symptoms, and treatment are all crucially important when discussing this disorder. Vitiligo is quite mysterious disease. Apparently, there is no known cause of it. Scientists believe that the immune systems of people who have vitiligo may accidentally destroy sections of the body. It is possible that the immune system will damage the melanocytes, cells that produce pigment, in...

Red patches with white grain like centers appear along the gum line in the mouth two to four days after the first symptoms show. These patches are called Koplik spots because Henry Koplick first noticed them in 1896. The Spots are important to diagnose measles. A characteristic red rash in measles is red spots starting at the hairline and going down to the face, body, and limbs. Measles usually ends with a complete recovery, but some rare complications can occur with the lungs and brain. Measles might also be linked with multiple sclerosis and diabetes. In 1978, the U.S. Public Health Service started vaccinating for measles. All school age children were vaccinated. Two years later the measles virus occurring went down 99 percent. Now days, measles is very rare and all children are vaccinated for it Measles is a highly contagious disease. It is caused by an RNA virus that changes constantly.
