Living a healthy and fit lifestyle has many key components in achieving the optimal way of living. If you were not to focus in on your diet or working out habits then it could affect your mental and physical health causing you to gain weight or maybe even potentially become obese, being able to do certain physical activities or make your social behaviors to decline. It can also have an impact on your children later down the road causing them to be at risk for certain diseases that are passed down from you to them when born. Don’t waste time! Our writers will create an original "About Health and Fitness" essay for you Create order Even though the benefits for improving your way of living sounds phenomenal, going from unhealthy to living your best life it can be a struggle and frustrating at times but can be achievable with time and patience. But an important note to take is that even though a certain study might tell you to do one thing in your lifestyle and another study will tell you something completely different even though it is over the same subject as well. That goes to show you that no one person is the same as you, so you will not have to do the same numbers as the book tells you to do. Having a proper diet is the hardest part of living a healthy lifestyle. We live in a society today where a fast food restaurant are around every corner that we adventure off to and knowing how great it tastes, how easy it is to access whenever you want it, and inexpensive it is, it is still terrible for you. Knowing the sodium and fat levels included in that meal are through the roof. Thats why there are certain laws out to help protect us from the food chains from going overboard with the things that can affect our health in a negative way. Eating good nutritional food is something you should include in your regular day to day bases. Dieting is your framework when it comes to the things you want to achieve in your healthy lifestyle. If you do not eat properly before you go to the gym, you will most likely have a bad day and you will not have an effective workout or cause you to get sick. Eating things like all of your vegetables especially your greens, red meats, and fish are needed . The major classes of nutrients are water, carbohydrates, fats, proteins, vitamins, and minerals.*pg50* all these are needed to help achieve your goal of healthy living. Drinking water, for example, is something that is one of those simple tasks that people ignore more often than not but is something that is so vital to your proper diet. Losing a low amount of the water in your body could cause you to lose your life because 70 percent of your body is made up of water. Water can only be replenished back into your body only if you intake it properly. Water is also very important in activating our fiber intake. The recommended 20 to 35 grams of daily fiber requires about six to eight glasses of water to be effective. Your daily water intake depends on the number of calories you expend. You need about one milliliter of water (1 ml = 1 cc=1/1000 L = 1/30 oz; 1 glass = 8 oz = 240 ml) for every calorie you burn. You lose water through sweat (24 oz), urine, feces, and breath air (12 oz) daily even when you are inactive.*pg52* When you first wake you, you have gone that whole night of sleep without water so the best thing to do is drink a bottle of water to k ick off your day and it will improve your day majorly When eating your foods that have carbohydrates in them that is how you get your body to function properly through your day. But know there are good and bad carbs. Good carbs include berries, apples, broccoli, grains, and dairy products. Bad carbs include sodas, cakes, mainly anything that includes loads of sugar. Fats are what give you all of your energy and are broken up into four groups. You have your two good fats, monounsaturated fats, and polyunsaturated fats which include nuts, seeds, and fish. These are usually easier to consume when snacking on these through the day. Your bad fats in Recent studies have shown that ones intake of saturated and trans fatty acids can be reduced by half by eliminating butter, margarine, dairy products containing 2 percent fat or whole milk, and meats with fat.*pg55* Proteins have amino acids and this is important because they repair, develop, and grow tissue. Eating eggs, meat with no fat, fish, and cheese are rich in protein and they are what make you grow. Proteins are highly needed for keeping our body functioning as well. Vitamins are needed in lower doses but still very important to your health. If maintained in a poor manner the lack of vitamins could leave you in a world of pain by damaging your liver and kidneys. If you believe you are not getting enough of the needed nutrients than you can take a vitamin supplement. However, if taken accessibly then it could lead to blindness, kidney stones, and liver injury. Having all of these different nutritional facts are a major key in you becoming more knowledgeable and now of a basis of what food to eat. Still dieting is what healthy living is framed around. If you can control what you eat, then you can do anything you set your mind to. The secret to having a healthy lifestyle is a balance. Without enough or too much of one thing still offsets certain parts of the body causing all these little ripple effects to be caused. You can not forget about the working out part of your lifestyle. It is important to work your body and build it back up. It causes you to even look better causing you to build your self esteem to rise as well. With all the different types of fitness there are out there, aerobic fitness is a way you can use to see and analyze how much oxygen you are getting to your muscles. Exercises included are walking, jogging, running, and even with you sitting and hearing this paper be presented. Incorporating this into your everyday routine for thirty minutes a day you will see an improvement in your breathing, feeling, and eating habits. Everything you do, you use oxygen and when you are delivering all the oxygen throughout your body it becomes easier to do a certain task. Achieving that weight loss goal of yours is very dependent on how many calories you are intaking. You slipped up and ate something you were not supposed to eat so you could go out and get your thirty to forty minute walk in. Now you are back to your original goal. Stretching and being flexible are here to save us from straining anything in our day to day basis when trying to complete a task. It is how well you can move your joints around in normal motion. For example, if you were to break your ankle and had been in a boot to keep your foot from moving around. All of your tissue, muscle, and ligaments are there staying in one spot. Once the boot is taken off, you try to move it around and all you hear are creaks and pops. Your ankle is not ready to be stretched at its full capacity yet. Normal activities like walking are impacted by this. When stretching to get your ankle back to tip top shape there are two different types of exercises, static and dynamic. In static stretching, you hold your certain muscle group at a point that is bearable for a couple of seconds, all while still controlling your breathing, then release. What this is doing is training your targeted area to reach that high point where you are stretching it too. Motivation is a key component is staying true to what you are wanting to accomplish. Taking pictures of your progress from the start to week four, to week eight, and the final result will give you that visible progression and show you that you are not just doing this for no reason. You are doing this, so you can look and feel better as well. Loving a healthy lifestyle brings along social status. If you look good and you know it, of course, the opposite sex will naturally gravitate to you. You are now walking around with that confidence you once never had. It feels good to be able to do things freely with no repercussion from it. Whether it be you getting out of bed pain free, going for a walk with your family, or throwing the baseball with your son. It all correlates with each other in the little everyday things we do. Do not take it for granted and take care of your body. It is the only one you have.

School Violence Essay - 1154 Words

Preventing school violence has been an issue in our society for so long it has almost become commonplace. According to an article on www.infoplease.com, since the year 2000, there have been a recorded 64 shooting related incidents that involved publicly occupied areas. That is an occurrence of almost five per year. Of those 64, 94% of these incidents were school related shootings. The violence goes from elementary schools all the way up to college universities. The statistics are not pretty by any means. So what are we to do? Should we institute better security? For all of these tragedies, it is time reasonable measures are finally taken to implement new methods of prevention and to address the school violence issues as a severely†¦show more content†¦Of the schools that have already implemented these checklists, many have begun to identify and suspend possible threats within the school. Of course, these threats are the students themselves. But what does this solve? What are the alternatives to using this checklist and helping a potentially dangerous student? Is this a solution or an excuse? The alternatives to profiling students can be divided up. You can have a parental approach, an approach by lawmakers, or a teacher’s approach. Seeking a parental approach is a touchy subject. An obvious positive parenting technique is that the parents are more involved in the lives of the children. That is so obvious it hurts. Many parents are not involved as much because of work, being a single parent, money, time, etc. If you are going to have a child in today’s society you should be prepared to do everything in your power to be involved. Carolyn Pereia, from the Educational Resources Information Center, suggests two things when raising children. Recognizing positive accomplishments and expectations academically and socially. â€Å"If key people in a child’s environment give clear and constant signals that violence is not the norm, children will be more likely to develop anti-violent patterns of behavior.† (Pereia 1) Being involved with your child is so much more than just going through the motions of daily lives.

Stakeholders According to Business Leaders free essay sample

The spirit of corporate citizenship suggests that a company that derives profit from the community has an obligation to contribute to its development. I t is reasonable to expect the principle of mutual obligation to apply to the business sector. John Howard, Prime Minister of Australia, 1998. (FN1). Debate has emerged regarding a shift of focus in the organizations relationships with its various stakeholder groups. In the past the company has been seen predominantly as an instrument of its owners. However, they point out that stakeholder theory does not necessarily presume that managers act as the rightful locus of corporate control and governance. Managers are often cast in the role of referees in the balance game between various stakeholders. This, however, does not take into account that managers are also employees and often investors. Therefore managers are themselves stakeholders, indeed a privileged class of stakeholder in the enterprise. (FN21) This suggests that managers may be motivated to practice opportunistic behavior. We will write a custom essay sample on Stakeholders According to Business Leaders or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Further, it leads to the argument that the subjective attitudes and motivations of managers may be a significant feature in organization-stakeholder relationships. Many authors claim that there is a lack of empirical research in the stakeholder area. (FN22) Marens, Wicks, and Huber suggest that looking more closely at specific stakeholder relationships would create a richer definition of a stakeholder managerial approach and help explain, even predict, the impact of this approach on performance. Several studies which examine stakeholder relations can, in fact, be found. FN23) Predominantly these studies investigate the link between stakeholder relationships and company performance. (FN24) It would appear that little attention has been given to the qualitative nature of specific stakeholder relationships. The present study examines the relationship between organizations and stakeholder groups as reported by the companys leaders. These groups include owners, employees, customers, supp liers, the environment, and community. The data that are presented and discussed in this paper focus on the community-stakeholder relationship. Open-ended questions were deliberately used in a semi-structured interview to allow the interviewee to define the various stakeholder groups themselves. The stakeholder group identified as community is particularly open to individual definition by business leaders due to the ambiguity which commonly surrounds the term. Community is an amorphous concept that the interviewers did not attempt to clarify. Under these conditions, therefore, community as a stakeholder entity is whatever the interviewee perceives it to be. The relationship described is a two-way relationship but it is defined from only one perspective. By allowing the interviewees to describe what they meant by community, and not imposing any external attributes in the term, we have minimized the impact of stakeholder-related attributes. METHODA study was undertaken to ascertain how Australian business leaders perceive their relationships with the wider community. A secondary aim of the research is to investigate the integration of social and environmental values in daily business activities. Twelve chief executive officers (CEOs) or managing directors from a range of companies were interviewed. These companies vary in terms of industry, organization size, ownership, organizational age, and structure (see Table 1). The CEOs were selected on the basis of accessibility and availability. A semi-structured interview schedule was used which incorporates 16 questions covering five areas of inquiry. The questions are open-ended and followed by neutral prompts. This schedule was used as an interview guide during an interview lasting between one and one and a half hours which was held at the CEOs offices. The interviews are analyzed using the editing approach to qualitative data. FN25) Editing analysis means that the researcher enters the text like an editor searching for meaningful segments: cutting, pasting, and rearranging until the reduced summary reveals the interpretive truth. The editing techniques have a cyclical quality: interpretations emerge from the analysis of a particular theme or category and then are repeatedly compared with the original textual data. This is called c onstant comparison, where eventually additional analysis no longer contributes in discovering anything new about a category.

Wireless communication Essay Example

Wireless communication Essay A type of wireless communication that is most familiar to mobile phones users. Its called cellular because the system uses many base stations to divide a service area into multiple cells. Cellular calls are transferred from base station to base station as a user travels from cell to cell. (Bellis) History * First concept introduced in 1947 * Incorporated technology from car phones * Purely theoretical and no technology existed to support * Dr.Martin Cooper, a Researcher for Motorola is credited with inventing the first cellular phone * The First Cell Phone The first cell phone was named the DynaTAC8000X. It was created by Martin Cooper in 1984. It took over a decade to develop and $100 million. There were only about 2,000of these cell phones available to the public. * Weight- 2 pounds could store only 30 phone numbers. Battery needed to be charged for 10 hours. Talk time- 1 hour! The phone cost $3,995!! Uses * Text messaging Entertainment Uses: Games, music (mp3 player), books (e-boo k), and digital television broadcast * Social Uses: phone  call, text message, wireless internet (access to e-mail, social networking websites) * Organization Uses: calendar, finance manager, address book, storage for data * Hospital Uses: Used to view image (x-ray, MRI, etc). Means  of communication between nurses and clinicians. * Museum Uses: audio guide is provided through cell phones. * Educational uses: mobile learning provides access to lectures and test preps. * Track the culprits, location of a person   Cell Phones revolutionized long distance calling, making it much more inexpensive for long distance communication. * Cell phone logs have also been helpful in court cases where they can be used as evidence. * Smart Phones arent only used for communication, but for organizing schedules, jotting down notes, playing music, games, checking the weather, and other applications How do mobile phones work? Mobile phones and their base stations transmit and receive signals using electromagnetic waves (also referred to as electromagnetic radiation or fields, or radio waves).Electromagnetic radiation is emitted by many natural and man-made sources and plays a very important part in our lives. All electromagnetic radiation consists of oscillating electric and magnetic fields and the frequency, for ? (nu), which is the number of times per second at which the waves oscillate, determines their properties and the use that can be made of them. Frequencies are measured in hertz or Hz, where 1 Hz is one oscillation per second,1 kHz or kilohertz is a thousand Hz, 1 MHz or megahertz is a million Hz, and 1 GHz or gigahertz is a thousand million Hz or 109 Hz.Frequencies between about 30 kHz and 300 GHz are widely used for telecommunication, including broadcast radio and television, and comprise the radiofrequency (RF) band. Cellular mobile phone services operate within the frequency ranges 872–960 MHz and 1710–1875 MHz. An RF wave used for radio communicat ion is referred to as a carrier wave. The information it carries – speech, computer data, etc – has to be added to the carrier wave in some way, a process known as modulation. The information can be transmitted in either analog/ Digital form. Mobile Net workA mobile phone sends and receives information (voice messages, fax, computer data, etc) by Radio communication. Radiofrequency signals are transmitted from the phone to the nearest base station and incoming signals are sent from the base station to the phone at a slightly different frequency. Once the signal reaches a base station it can be transmitted to the main telephone network, either by telephone cables or by higher frequency (such as 13, 23 or 38 GHz) radio links between an antenna (eg dish) at the base station and another at a terminal connected to the main telephone network.These microwave radio links operate at rather low power and with narrow beams in a direct line of sight between the antennas, so that a ny stray radiation from them is of much lower intensity than the lower frequency radiation transmitted to the phones. Radiation Pattern of a Cell tower Signals to and from mobile phones are usually confined to distances somewhat beyond the line of sight.They can reach into buildings and around corners due to various processes including reflection and diffraction, that allows the radiation to bend round corners to some degree, but the coverage area from a base station is partly governed by its distance to the antenna’s horizon. An ideal network may be envisaged as consisting of a mesh of hexagonal cells, each with a base station at its centre but in practice the coverage of each cell will usually depart appreciably from this because of the topography of the ground and the availability of sites for the base stations.The sizes of the cells are usually less than the 35 km maximum because obstruction by hills, buildings and other ground features reduces the effective range. Freque ncies are reused several cells away and the capacity of a network (the number of simultaneous phone calls which may be made) depends on the extent of the frequency spectrum available, the cell diameter and the ability of the system to work against a background of interference from other cells.To accommodate the steadily increasing volume of users, cell sizes have to be progressively reduced (for example, by using base station antennas of lower height and reduced power) so that the frequencies may be reused more often. Indeed in large cities, base stations may only be a few hundred metres apart. Power output of the base stations are naturally more powerful and continuous in nature and they are received at close quarters for a longer period of time. People are not supposed to reside within 100 meters from the base stations in urban areas and within 300 meters in rural areas.Measure of RF Density: A SAR value is a measure of the maximum energy absorbed by a unit of mass of exposed tiss ue of a person using a mobile phone, over a given time or more simply the power absorbed per unit mass. SAR values are usually expressed in units of watts per kilogram (W/kg) in either 1g or 10g of tissue CDMA mobiles like those of Reliance and Tata Indicom have 1 Watts output; The GSMA mobile like BSNL, Idea and Airtel have 2 Watts and the US Analogue mobiles have a power output of approximately 3. watts. The SAR rating of each individual phone model is now being displayed on all mobile phone packaging in both the US and the UK, which will enable users to make informed choices when purchasing a handset. SarValues. Com brings this important information free of charge to all cellular users and also provides useful links to other Websites containing information. Whatever the outcome of the mobile phone debate, it makes sense to use prudent measures to reduce your radiation exposure, if possible.An obvious way to accomplish this, is by choosing a phone with a lower Sar Value. The point is to show that SAR Is not a property of a device itself, but a combination of a device and the way it is used. Mobile phones are now a large part of our every day life, they are probably the most useful gadget ever invented! The thing is though, every now and again research comes forward suggesting that mobile phones should be used responsibly, as the evidences are fast coming up to be displayed having its impace in Human health, environment and society.Biological Effects : Many scientific studies have investigated possible health symptoms of mobile phone radiation. These studies are occasionally reviewed by some scientific committees to assess overall risks. A 2007 assessment published by the European CommissionScientific Committee on Emerging and Newly Identified Health Risks (SCENIHR ) concludes that the three lines of evidence, viz. animal, in vitro, and epidemiological studies, indicate that exposure to RF fields is unlikely to lead to an increase in cancer in humans. Thermal effects :One well-understood effect of microwave radiation is dielectric heating, in which any dielectric material (such as living tissue) is heated by rotations of polar molecules induced by the electromagnetic field. In the case of a person using a cell phone, most of the heating effect will occur at the surface of the head, causing its temperature to increase by a fraction of a degree. In this case, the level of temperature increase is an order of magnitude less than that obtained during the exposure of the head to direct sunlight. The brains blood circulation is capable of disposing of excess heat by increasing local blood flow.However, the cornea of the eye does not have this temperature regulation mechanism and exposure of 2–3 hours duration has been reported to produce cataracts in rabbits eyes at SAR values from 100-140W/kg, which produced lenticular temperatures of 41 °C. There were no cataracts detected in the eyes of monkeys exposed under similar conditions. Pre mature cataracts have not been linked with cell phone use, possibly because of the lower power output of mobile phones. Non-thermal effect: The communications protocols used by mobile phones often result in low-frequency pulsing of the carrier signal.Whether these modulations have biological significance has been subject to debate. Some researchers have argued that so-called non-thermal effects could be reinterpreted as a normal cellular response to an increase in temperature. The German biophysicist Roland Glaser, for example, has argued that there are several thermoreceptor molecules in cells, and that they activate a cascade of second and third messenger systems, gene expression mechanisms and production of heat shock proteins in order to defend the cell against metabolic cell stress caused by heat.The increases in temperature that cause these changes are too small to be detected by studies such as REFLEX, which base their whole argument on the apparent stability of thermal equil ibrium in their cell cultures. Other researchers believe the stress proteins are unrelated to thermal effects, since they occur for both extremely low frequencies (ELF) and radio frequencies (RF), which have very different energy levels.Another preliminary study published in 2011 by The Journal of the American Medical Association conducted using fluorodeoxyglucose injections and positron emission tomography concluded that exposure to radiofrequency signal waves within parts of the brain closest to the cell phone antenna resulted in increased levels of glucosemetabolism, but the clinical significance of this finding is unknown. Blood–brain barrier effects: Swedish researchers from Lund University (Salford, Brun, Persson, Eberhardt, and Malmgren) have studied the effects of microwave radiation on the rat rain. They found a leakage of albumin into the brain via a permeated blood–brain barrier. This confirms earlier work on the blood–brain barrier by Allan Frey, Osc ar and Hawkins, and Albert and Kerns. Other groups have not confirmed these findings in in vitro cell studies or whole animal studies, however Frey alleges that an editor determined that a researcher who claimed that his attempts to replicate Freys research had not validated Freys results had incorrectly interpreted his own results, and that his research had confirmed Freys results.Cancer: The International Journal of Epidemiology published a combined data analysis from a multi national population-based case-control study of glioma and meningioma, the most common types of brain tumour. The authors reported that the wall of capillaryblood vessels situated in the brain are very thin made up of single layer of endothelial cells. Microwaves trigger changes to protein structures in endothelial cells,allowing toxins to enter the brain and making them tumorous. Mobile phones can affect pacemakersUnder certain circumstances, mobile phones can have adverse effects on the function of pacemake rs, but the devices usually start working properly again once the phones are moved away, researchers in Turkey report. The most essential recommendation to patients according to thereport is that mobile phones must be kept at least 20 cm away from pacemakers. For this purpose, it is sufficient for patients not to use the ear on the side of the pacemaker while talking on the mobile phone and not to carry the mobile phone in the shirt pocket on the side of the pacemaker.Infertility Problems : Using a hands-free device with a cell phone may affect fertility if phone is kept close to the testicles, Cleveland Clinic researchers warn in the journal Fertility and Sterility. Men who use these hands-free devices tend to carry their cell phones in their pants pocket or clipped to their belts at the waist while in talk mode have impact on semen quality. As a result, they may be exposing their testicles to damaging radiofrequency electromagnetic waves, explains Ashok Agarwal, PhD, head of the a ndrology laboratory and the irector of the Center for Reproductive Medicine at the Glickman Urologoical and Kidney Institute at the Cleveland Clinic in Ohio. Cell Phones Effect on environment: We are living in an environment filled with artificial radiations. The electromagnetic radiation playing role in the decline of animal and insect population. The EMR is so powerful that it affects the biological systems of birds, insects, even humans. In September 2010, the ministry established a ten member committee under Bombay Natural History Society (BNHS) with director Asad Rahmani to study the impact of cell phone towers on birds and bees.This group of experts reviewed 919 studies performed in India and abroad. Of the 919 studies, 593 showed the negative impact of mobile towers on birds, bees, humans, wildlife and plants. Effect on farm animals * Dairy cows- Decreased milk production, spontaneous abortions, reproductive and developmental problems, and general decline in overall health. * Sheep dogs, cats, rabbits living near base stations affected. Cell phones and Birds * Sparrows have disappeared completely from the cities at least four years ago in Britain as mobile phones grew in popularity. 3G mobiles were introduced in 2003; there are 65 million users in UK by 2005. In a research by Spain conservation biologist Alfonso Balmori there is difference in how the birds behaved close to the phone antennae. * Young birds die from unknown causes. Bird couples frequently fought, while constructing their nests stick fell to the ground. * Some nests were never completed and the storks remained passively in front of antennae. * Laboratory studies show bird embryo die when exposed to microwaves. Effect on Biodiversity * Electromagnetic radiations of mobile phones are directly related with the disturbance in ecosystem and ultimately biodiversity. 230 species (several million birds) die each year from collisions with telecommunications in the United States during migration. * Birds have thin skulls. Accidents happen mainly in night, in fog, bad weather when birds might be using the earth’s magnetic field for navigation. Effect on chicks According to a study 75% chick embryos died due to exposure to cell phone Effect on rabbits 2 to 3 hours exposure of rabbits to electromagnetic radiations showed cataracts because cornea doesn’t have thermal regulation. Bacteria and cell phones:The problem with phones is that we are in constant contact with them, and we spend a lot of time in close proximity to our faces and mouths and because it’s an electronic device, most people are hesitant about cleaning them. The cell phone has 10 times more germy than a toilet seat. Infectious microbes on the surface of a Smartphone including staphylococcus have an excellent chance of making their way to your eyes, nose and mouth Effect on Honey bees: Scientists may have found the cause of the worlds sudden dwindling population of bees and cell phones may be to blame.Research conducted in Lausanne, Switzerland has shown that the signal from cell phones not only confuses bees, but also may lead to their death. Over 83 experiments have yielded the same results. With virtually most of the population of the United States (and the rest of the world) owning cell phones, the impact has been greatly noticeable. Led by researcher Daniel Favre, the alarming study found that bees reacted significantly to cell phones that were placed near or in hives in call-making mode. The bees sensed the signals transmitted when the phones rang, and emitted heavy buzzing noise during the calls.The calls act as an instinctive warning to leave the hive, but the frequency confuses the bees, causing them to fly erratically. The study found that the bees buzzing noise increases ten times when a cell phone is ringing or making a call aka when signals are being transmitted, but remained normal when not in use. The signals cause the bees to become lost and disoriented . The impact has already been felt the world over, as the population of bees in the U. S. and the U. K. has decreased by almost half in the last thirty years which coincides with the popularization and acceptance of cell phones as a personal device.Studies as far back as 2008 have found that bees are repelled by cell phone signals. Bees are an integral and necessary part of our agricultural and ecological systems, producing honey, and more importantly pollinating our crops. As it is unlikely that the world will learn to forgo the convenience of cell phones, it is unclear how much they will contribute to the decline of bees, and their impact on the environment. Effects of cell phones on society The effects of cell phones on society will always be a double edged sword. The debate is never ending.Both sides have compelling arguments. But although there are some disadvantages, when looking around, one of the first sights I see are people walking with one hand up to their ear, like an e vidence that cell phones have become important in our daily life. One effect of cell phones on society is availability to keep in touch with family, friends or business partners almost in every place and every time. You do not have to wait until evening, when you will be at home, or find a telephone boxes to call some friend or family member, if you have to tell them something important.Moreover – cell phones are the perfect way to stay connected with others in the event of emergency. They provide us with a sense of security. In the event of emergency or loss cell phone can allow others to connect with you quickly and could possibly save your life. If you feel insecure or something has happened to you or to a person next to you, you can call to get help. For instance, most of Americans (about 74%) who use cell phones say they have used their mobile device in a critical situation and gained valuable help. Besides that today cell phones are more and more easily to use.They are capable of not only receiving and making phone calls, but taking, sending and receiving photos, sending data, you can use the Internet to check your e-mail, a calendar to plan your time, an alarm clock or a calculator. In short – nowadays cell phones are useful in different daily situations. But all opinions could never be the same. Some people believe that cell phones influence us negative. They say – health problems are one of the results of owing a cell phone. That is because of the negative radiation, what they have, when the phone is in your pocket or next to you.However scientists still have not proved the badness of.. Recommendations: The International Commission for Non-ionizing Radiation Protection is the authority for monitoring Ionizing radiation of mobile phones and Base Stations. This body has spelled out definite guidelines for the radiation levels allowed and the base station lists are classified accordingly Now let us see the recommendations for safe us e of mobiles: Various steps to be followed to decrease the burden of Radiation Effect: * Step1 Minimize the duration of use, since certain effects of electrmagnetic radiation (e. . thermal effects on brain) are accumulative. One should not talk for more than three minutes at a stretch and should take at least 15 minutes break in between calls. * Step2. Use hands-free to decrease the radiation to the head. Accidents caused by inattension are still there in this situation. * Step 3. Keep the cell phone away from the body. Use a speaker phone or the head set. * Step 4. Limit the use of cell phone by children. * Step 5. Avoid living near the base stations * Step 6. Avoid phone usage while crossing the street. * Step 7.Never use a cell phone when a conventional phone is available. * Step 8. Mobile phones should be prohibited near Intensive Care Units and Operation theatres. * Step 9. The practice of installing antennas needs to be regulated. * Step 10. The specific absorption rate (SAR) value for each hand set should be provided by the manufacturers on the website as well as in the user’s manual, as per the International Commission on Non-Ionizing Radiation Protection guidelines. * Please take this into consideration and use caution on your phones. * You tell everyone on the road and off the phone.Future Perspectives: As the present day world is more dependent on Mobile phone in their day to day life ,there is need for researcher to discover mobile phones that emit less radiation. RADISAFE  , is one such invention. It is an anti radiation mobile chip reduces over  99. 95%  of radiation emitted from your mobile phone, and makes your mobile phone totally harmless as certified by the worlds premier electronics testing laboratory,  california institute of electronics and materials sciences, USA. But for its application in the market , there is a long way to go.

Piebald Argument

Dapple/Piebald Argument Free Online Research Papers Let me start by saying, the following information is my personal opinion and response to other, unnamed websites. You can take what I have to say at face value. If you do not like it, that is fine, everyone is entitled to their own opinions. If you understand my reasoning, great, if not, that is your choice. I would like to say, dont believe everything you read on the web. For every one website with logical, clinical, and actual correct information, you can find at least one with incorrect information or information where people try to present their personal opinions as gospel without stating that the information is ONLY their opinion. Ok I am going to pick out quotes from some websites that I have found and refute those comments. Please understand, I am not attacking the person(s) who put these comments on their websites. I am just giving my opinion about the information that is out there. On one website I found someone who says: Any dapple piebald dachshund puppy has clearly come from a puppy mill/commercial puppy producer or backyard breeder. Well to this I have to say BS! There are breeders who actually breed for this color. Yes, it is an unusual color and at the moment AKC does not accept it, but there was a time when AKC did not accept other patterns and/or colors. Who knows, maybe someday they will. If you have a dappled piebald, it is true that your dog be shown through AKC, EVEN if your dog is PERFECT in every other way. The ONLY reason it cannot be shown through AKC is because this pattern is not recognized by the organization. Still, just because a dachshund is showing a mixed pattern does no t mean it is not a quality and/or well bred dachshund. I do not actually breed for this pattern but I have had 2 puppies in 8 years that have both patterns. Each of the puppies produced are 100% healthy and neither of them have any hearing or sight problems. I breed for beautiful, healthy, quality, happy, puppies and I believe that I have stood by and accomplished that goal and will continue to in the future. The same webpage that supports the comment above says: Only experienced breeders should attempt double dapple breeding, as deaf and partially deaf puppies may result from this breeding. Come on, give me a breakwhy does it matter if someone off the street is breeding two dapples together or if they are being bred by an experienced breeder. Does an experienced breeder have some way to insure that there is NO chance that the puppies will have ANY genetic problems because of the duel dapple genes? Do they have a way of placing the correct genes where they want them on the puppys DNA so they can be sure the pup comes out normalif they do, gosh spread it around, I would like to know how to play genetic god. In my opinion, if the author of the website that says that dappled piebalds come from bad breeders or puppy mills then how could he/she possibly condone the breeding of double dapples? In addition, the webpage that I am getting these quotes from says: GOOD piebalds that truly look like Dachshunds ARE rare. What the heck does that mean? There are some awesome piebalds out there that have perfect stature for the dachshund. What the heck does the piebald pattern h ave to do with conformation? It is a PATTERN! He/she says: Piebald is not a pattern which is described by the AKC Official Standard of the Dachshund, but it is an old pattern which has existed from the breeds early origins. Ok. so if this pattern has been around this long, than why does it not hold the same genetic cues for stature as the black and tan or the red. Geez, this person really makes NO LOGICAL SENSE! This comment is like saying 2+2 equals 4 but it looks like 5 because it has been around so long. *Quotes taken from a website. I will not disclose this website due to the fact that I do not wish to disrespect the author of the website where I got the quoted information. I am just refuting the website author’s information because I choose to disagree with the arguments that are presented.

Coloring Carnations Science Experiment

Coloring Carnations Science Experiment This fun home or school experiment shows your child how water flows through a flower from stem to petals, changing the color of carnations. If youve ever had cut flowers in a vase around the house, your child might have observed the water levels dropping. Your child may wonder why you have to keep watering houseplants. Where does all that water go? The Coloring Carnations Science Experiment helps to demonstrate that the water isnt just vanishing into thin air. Plus, in the end, youll have a very pretty bouquet of flowers. Materials You Will Need White carnations (1 for each color you would like to try to create)empty water bottles (1 for each carnation)food coloringwater24 to 48 hoursColoring Carnations Recording Sheet Directions for Coloring Carnations Experiment Peel the labels off the water bottles and fill each bottle about one-third full of water.Have your child add food coloring to each bottle, about 10 to 20 drops to make the color vibrant. If you would like to try to make a rainbow bouquet of carnations, you and your child will need to mix the primary colors to make purple and orange. (Most boxes of food coloring include a bottle of green.)Cut the stem of each carnation at an angle and place one in each water bottle. If your child wants to keep a picture diary of what is happening to the carnations, download and print the Coloring Carnations Recording Sheet and draw the first picture.Check the carnations every few hours to see if anything is happening. Some of the brighter colors may begin to show results in as little as two or three hours. Once you begin to see visible results, its a good time to have your child draw the second picture. Just remember to record how many hours have gone by!Keep an eye on the flowers for a day. By the en d of day one, the flowers should really be taking on color. Its a good time to ask your child questions about what shes observing. Try questions along the line of:Which color is working the quickest?What color isnt showing up well?Why do you think the carnations are turning colors? (see explanation below)Where is the color showing up?What do you think that means about which parts of the flower get the most food? At the end of the experiment (either one or two days, it depends on how vibrant you want your flowers to be) gather the carnations into one bouquet. It will look like a rainbow! Recording Sheet for the Coloring Carnations Science Experiment Make a four-box grid for your child to draw pictures of what happened in the experiment. What we did first: After ___ hours: After 1 day: What my flowers looked like: Coloring Carnations Science Experiment Why the Carnations Change Color Like any other plant, carnations get their nutrients through the water they absorb from the dirt they are planted in. When the flowers are cut, they no longer have roots  but continue to absorb water through their stems. As water evaporates from the leaves and petals of the plant, it sticks to other water molecules and pulls that water into the space left behind. The water in the vase travels up the stem of the flower like a drinking straw and is distributed to all of the parts of the plant that now need water. Since the nutrients in the water are dyed, the dye also travels up the stem of the flower.
