...Why do we use sunscreen? Sun poses many dangers to our health, particularly on our skin. The sun releases harmful radiation which can permanently damage the skin and can cause skin cancer, precancerous changes in the skin, as well as premature wrinkling and signs of aging. Apart from these effects it causes the usual sunburn. A sunburn is basically a burn which is caused by too much exposure to the ultraviolet radiation of the sun. Like other burns, sunburns can cause first degree burns, which are the most common type. With a first degree burn, a child's skin will be red and painful, but there will be no blisters. More severe or deep sunburns can lead to second degree burns, with the formation of blisters on the skin, and more rarely, third degree burns. Excessive exposure to sun is bad because of ultraviolet radiation, 90 percent of which comes in the form of Ultraviolet A (UVA) rays that are not absorbed by the ozone layer and penetrate deep into our skin. Ultraviolet B (UVB) rays make up the rest. UVB rays are partially absorbed by the ozone layer, which makes preserving the ozone layer crucial for our health. And because UVB rays don’t penetrate our skin as deeply, they can cause those lobster-red sunburns. Both types of UV rays are thought to cause skin cancer. Some of the possible mechanisms for UV skin damage are collagen breakdown, the formation of free radicals, interfering with DNA repair, and inhibiting the immune system. To prevent this, the most...

...The sun's rays make us feel good, and in the short term, make us look good. But our love affair isn't a two-way street: Exposure to sun causes most of the wrinkles and age spots on our faces. Consider this: One woman at age 40 who has protected her skin from the sun actually has the skin of a 30-year-old! We often link a glowing complexion with good health, but skin color from being in the sun – or in a tanning booth – actually speeds up the effects of aging and increases your risk for developing skin cancer. Sun exposure causes most of the skin changes that we think of as a normal part of aging. Over time, the sun's ultraviolet (UV) light damages the fibers in the skin called elastin. When these fibers break down, the skin begins to sag, stretch, and lose its ability to go back into place after stretching. The skin also bruises and tears more easily taking longer to heal. So while sun damage to the skin may not be noticeable when you're young, it will definitely show later in life. Ultraviolet (UV) radiation from the sun is the number-one cause of skin cancer, but UV light from tanning beds is just as harmful. Skin cancer is the most widespread form of all cancers in the U.S. and the number of cases continues to rise. It is the uncontrolled growth of abnormal skin cells. This rapid growth results in tumors, which are either benign (noncancerous) or malignant (cancerous). There are three main types of skin cancer: basal cell carcinoma, squamous cell carcinoma and melanoma....

...Plastics are all around us. There are many different kinds, with a wide range of properties. Some are hard, others are soft. Some are transparent, others are opaque. Most plastics are made in factories, but here’s one you can make at home. For this experiment you will need: * 1 teaspoon (5 cm3) laundry borax * 1 tablespoon (15 mL) white glue (e.g., Elmer's Glue-All) * food coloring (optional) * two cups * spoon * water Here's what to do: 1. In one of the cups, dissolve 1 teaspoon of laundry borax in 5 tablespoons (75 mL) of water. You will need to stir this for a while to get it to dissolve. (If a tiny bit does not dissolve, that is OK.) 2. In the other cup, combine 1 tablespoon of water and 1 tablespoon of white glue. If you wish, you may color the mixture with a couple drops of food coloring. With a clean spoon, stir the mixture thoroughly until it is uniform. 3. Put 2 teaspoons of the borax solution from the first cup into the glue mixture in the second cup. Stir the mixture. 4. As you stir the mixture, it will stiffen into a soft lump. After the lump has formed, take it from the cup and knead it in your hand for a couple minutes. The material you have made is called Gluep, and it is ready for you to examine. * Roll the Gluep into a ball and then let it rest. Does the ball maintain its shape? * Drop a Gluep ball onto a table top. What does the ball do? * Flatten the Gluep into a thin strip. Hold up the strip by one end. What...

...similar to a severe sunburn. This skin condition is the first stage of a developing pressure ulcer. a. Nurses should be aware that a patient with limited mobility is at risk for skin breakdown, and pressure ulcers. Anyone with limited mobility should be assisted to change positions by the care providers on a regular schedule to help circulation and prevent skin breakdown. b. Providers should also consider that the patient is 72, and has fragile skin due to aging skin. This also places the patient at further risk for pressure ulcers. c. The patient is also on restraints, which limits mobility even further. While restraints can help confused patients from falling, they can also cause skin damage. Care providers should continually access the need for using restraints, and remove them as soon as possible. B) Using hospital data on nursing sensitive indicators could advance quality care throughout the hospital. In this case, the hospital should examine the incidence of pressure ulcers, the use of restraints, and dietary requests. a. When examining the pressure ulcers, the hospital should consider what type of patients are acquiring them? Does it happen on a specific unit more than others? If so, what are the staffing ratios on that unit? Are they implementing pressure ulcer prevention protocol? If not, the staff needs to be educated about pressure ulcer prevention and what patient populations are at high risk for skin break down and...

...blocks of your body. Normally, your body forms new cells as you need them, replacing old cells that die. Sometimes this process goes wrong. New cells grow even when you don't need them, and old cells don't die when they should. These extra cells can form a mass called a tumor. Tumors can be benign or malignant. Benign tumors aren't cancer while malignant ones are. Cells from malignant tumors can invade nearby tissues. They can also break away and spread to other parts of the body. Most cancers are named for where they start. For example, lung cancer starts in the lung, and breast cancer starts in the breast. The spread of cancer from one part of the body to another is called metastasis. Symptoms and treatment depend on the cancer type and how advanced it is. Treatment plans may include surgery, radiation and/or chemotherapy. Doctors often cannot explain why one person develops cancer and another does not. But research shows that certain risk factors increase the chance that a person will develop cancer. Cancer can take decades to develop. That's why most people diagnosed with cancer are 65 or older. While it's more common in older adults, cancer isn't exclusively an adult disease. Cancer can be diagnosed at any age. Certain lifestyle choices are known...

...What are scientist doing to solve the problem of psoriasis? Psoriasis is an immune-mediated disease , which is abnormal activity of the body's immune system, in which the T-cells behave abnormally this then affects the skin.(1) Psoriasis happens when the skin replacement process speeds up, taking just a few days to replace skin cells that usually take 21-28 days, the skin cells build up , instead of shedding the extra skin cells they form raised areas on the skin, which can be flaky, scaly or red. (2)There is not a fully understood cause of psoriasis, but it is believed to have a genetic component, and is believed to be triggered by stress and/or injury to the skin.(3)It’s also believed that people with psoriasis have an increased risk of cardiovascular disease. The main solution, have you heard of phototherapy? Evaluation of reference one: Reference one is a reliable source because it is registered charity, this is updated by medical trustees who are qualified in dermatology. This information is not biased either, this is also because of the fact that it is from a medical point of view so there are only facts stated. This information is up to date too because the charity needs to keep people updated regularly with any new information that may occur. Evaluation of reference 4: Reference four is a reliable source because it is a national foundation which means lots of people will be viewing what they are saying so they must have their facts correct.

...see “Acknowledgements”). DNA fails to repair or kill itself (apoptosis) after being damaged which will causes DNA mutation. DNA mutation in a certain gene can make cells grow “out of control”. In human cells, the process of repairing DNA damage which occurs within chromatin is called Nucleotide Excision Repair (NER). Increasing age will decrease DNA ability to repair itself; this explains why a majority of cancer patients appear to be older adults. Ultraviolet radiation (UV radiation) is the main cause of skin cancer. Chromatin in skin cells after UV irradiation are found to...

...FUNCTIONS OF THE INTEGUMENTARY SYSTEM The integumentary system has many functions, most of which are involved in protecting you and regulating your body’s internal functions in a variety of ways: · Protects the body's internal living tissues and organs · Protects against invasion by infectious organisms · Protects the body from dehydration · Protects the body against abrupt changes in temperature · Helps dispose of waste materials · Acts as a receptor for touch, pressure, pain, heat, and cold · Stores water and fat Skin structure The skin is the largest organ of the body. It has three main layers, the epidermis, the dermis and the subcutaneous layer. The epidermis is an elastic layer on the outside that is continually being regenerated. It includes the following: Keratinocytes - the main cells of the epidermis formed by cell division at its base. New cells continually move towards the surface. As they move they gradually die and become flattened. Corneocytes - the flattened dead keratinocytes that together make up the very outer layer of the epidermis is called the stratum corneum or horny layer. This protective layer is continually worn away or shed. Melanocytes – produce the pigment melanin that protects against UV radiation and gives skin its colour. The dermis is the inner layer that includes the following: Sweat glands – produce sweat that travels via sweat ducts to openings in the epidermis called pores. They play a role in temperature regulation...

...Part 2 Individual Project Report: Lights Introduction There are many types of sources of light in the world. Amongst the most commonly used would be the light bulb. Furthermore, as Prof. Seeram thought of the project by looking at items found in everyday usage, I would assume that the light source in question would be the compact fluorescent light (CFL) bulb. It consists of glass vacuum tubing coated inside with luminophore; this tube contains mercury and argon with an electrode on each end, which is coated in an emission material (Mishra) (Acton). There is also ballast, ballast housing and its base but we will be focusing on the vacuum tube, electrode and ballast housing in this project. Fig 1. Inner workings of CFL bulb Types of material used Looking at the vacuum tube electrode and ballast housing, Table 1 below shows the materials used for each component (Hengdian Group Tospo Lighting Co.,Ltd.).

...* ------------------------------------------------- Six Vices Destroy the Human Life * Some people may think that people are the strongest in the nature. In fact, the human body is rather tender to be threatened by various vices, such as the inadequate intake of water and excessive intake of coffee. These vices can gradually destroy our life. The first vice is to drink water inadequately, which can cause the aging of brain, induce the cardiovascular diseases and affect the metabolism of kidney. When people are working in office, they usually forget to drink water. In order to prevent the danger, people should absorb enough water for their bodies. However, people with weak intestinal functions should not drink water until they feel thirsty, or the metabolism of water inside the body can be seriously disturbed. The second vice is to regard fruits as main food. Although fruits contain abundant vitamins and sugar, they can not provide protein and trace elements for the human body. The inadequate supplementation of protein will cause nutritional imbalance and induce various diseases. It is necessary for people to know well about their own physical constitutions so as to choose suitable food. The third vice is to drink wine excessively. It is known to all that excessive drinking can cause the liver diseases and affect the reproductive system. If people want to drink wine, they should first understand the variety of wine. It is beneficial for people to drink red grape wine moderately...

...All of Us Are Sexual Why is sexuality so important? All of us are sexual. Our sexuality includes our body and how our body works our biological sex our gender — our biological, social, and legal status as girls and boys, women and men our gender identity — our feelings about our gender our sexual orientation — straight, gay, or bisexual our values about life, love, and the people in our lives And sexuality influences how we feel about all of these things and how we experience the world. When we think of sexuality, we might just think about our bodies. We might just think about our sex organs. But our sexuality has as much to do with how we think and feel as it does with how we behave. Sexuality is a basic part of our physical, mental, emotional, and spiritual lives. Our sexuality should be enjoyed and celebrated. It is not something to be ashamed of or embarrassed about. Healthy sexuality allows us to be open, flexible, creative, safe, and responsible as we explore our sexual thoughts, feelings, and desires. It lets us recognize that sex can be fun and can also fulfill many emotional needs. Sex also has risks. Having a healthy attitude about sexuality means knowing our values, beliefs, attitudes, limits, and boundaries, and respecting that knowledge by being responsible. It allows us to feel attractive, regardless of our age, gender, sexual orientation, race, religion, height, weight, or physical or mental ability. It lets us be ourselves. Knowing as...

...It depends. You might be having a day filled with emotions: sadness, joy or exhaustion. Sometimes the safe touch, music that brings up memories, dates that are linked to events, or the smell of the massage oil may release feelings. The body can react by crying, laughing, or "shivering from cold." The mind can also become absorbed in the feelings rather than the massage. Your therapist will simply ask if you are okay to continue receiving touch and given your answer, he or she will monitor how you are doing and adjust the session goals accordingly. For example, he or she may shorten the time, change the strokes or the music or add more draping. WILL THE OILS USED MAKE ME BREAK OUT? Most massage therapists use hypoallergenic massage oils or lotions. However, if you have sensitivity to certain types of oils or lotion please bring it to the massage therapist's attention as most practitioners have an assortment of oils and lotions on hand. Will the OIL RUIN my CLOTHES or MESS my HAIR? Most massage oils will not damage your clothing. If you have any concerns, bring a comfortable set of clothes to put on afterward. A well-trained therapist can design a session that does not mess up your hair or make-up. IS A MASSAGE THERAPY SESSION ALWAYS...

...The Emperor Penguin and its Endangered Enviroment The emperor penguin is one of the most interesting species of penguin. This flightless animal lives on the Antarctic ice and in the frigid surrounding waters. This bird has a life span of 15-20 years and lives in colonies. Its diet is mainly that of a carnivore. The majority comes from fish. With all the beauty and intriguing life style of this penguin, not all is good. This penguin is in danger. What is causing this danger? It is not any predator in its wild habitat, it’s the effect of human ignorance. Climate change is slowly destroying the ice the penguin lives on. The emperor is on a downward spiral in which extinction is possible at the end of this century. With climate change at a dangerous level, warming may melt sea ice at rates which will decrease its habitat to nothing. With all these dangers there is still more, over fishing by humans is depleting the food source. In this paper I will outline and describe the problems these penguins face. I will also give a brief background on this flightless bird. Emperor is the largest of all penguins—an average bird stands some 45 inches (115 centimeters) tall. Penguins withstand physiological adaptations and cooperative behaviors in order to deal with an incredibly harsh environment, where wind chills can reach -76°F (-60°C)(Van Woert, Michael). They huddle together to escape the wind and reserve the warmth. Individuals take turns moving to the group's protected and relatively...
