Cleanliness Free Essays

What is Cleanliness? Since the germ theory of disease, cleanliness has come to mean an effort to remove germs and other hazardous materials. A reaction to an excessive desire for a germ-free environment began to occur around 1989, when David Strachan put forth the â€Å"hygiene hypothesis† in the British Medical Journal. In essence, this hypothesis holds that dirt plays a useful role in developing the immune system; the fewer germs people are exposed to in childhood, the more likely they are to get sick as adults. We will write a custom essay sample on Cleanliness or any similar topic only for you Order Now The valuation of cleanliness, therefore, has a social and cultural dimension beyond the requirements of hygiene for practical purposes. Influence of cleanliness on an individual’s life The significance of cleanliness and hygiene cannot be overlooked by any society. Every faith and civilization stresses the importance of cleanliness. Historically, cleanliness has been considered one of the important factors by which to judge a civilization’s or society’s development. Islam places great emphasis on cleanliness and purity, both physically and spiritually. In Islam, spiritual purity is linked to physical cleanliness and purity. More importantly, cleanliness is termed an indispensable fundamental of faith. However, this fundamental and powerful tenet of our faith, unfortunately, is not reflected in our society practically. Serious reflection is required on our individual as well as collective practices in order to make this valuable principle of Islam part of our lives. There are many verses in the Holy Quran which reflect the importance of cleanliness. For example, Allah says â€Å"†¦Truly, Allah loves those who turn to Him constantly and He loves those who keep themselves pure and clean† (2:222). In the Quran worship and seeking Allah’s love is conditioned with cleanliness and purity as the Holy Book says â€Å"†¦In it [mosque] are men who love to clean and to purify themselves. And Allah loves those who make themselves clean and pure† (9:108). Furthermore, in one of his sayings the Holy Prophet (PBUH) has termed cleanliness as half of faith. The above few examples from the Holy Quran and sayings of the Holy Prophet reveal that without cleanliness of our body and environment, one cannot receive the proximity of Allah spiritually and most importantly, faith cannot be completed in the absence of cleanliness and purity. Much is said rhetorically about cleanliness in our society but practically its application is missing. A quick observation can reveal how insensitive a culture we have developed regarding cleanliness and hygiene. Throwing garbage in the streets, roads or parks has become a common practice in our society. In public places dustbins are seldom found. Even if dustbins are installed, people do not use them properly. Rather, they prefer to throw garbage outside them. It is also observed that people clean their homes and shops and throw the garbage on the street without considering its implications. It is evident that even students of elite schools throw garbage on the ground even in the presence of garbage bins. This shows our attitude towards cleanliness and hygiene. Another habit that is commonly found in our society is spitting openly. People spit paan from running vehicles without considering the pedestrians walking on the road. This practice not only affects the environment but is also an eyesore. Another area that needs consideration is the horrible condition of public toilets. The shortage of public toilets is a big challenge, hence people are compelled to use open spaces to answer the call of nature. The toilets that do exist are in such pathetic condition that one cannot use them. There are many other examples which can be cited to indicate the pathetic condition of cleanliness and hygiene in our society. Hence, conscious efforts are needed to tackle this issue. There is a dire need to educate and sensitise people about the importance of cleanliness in light of our faith. In this regard social institutions such as educational institutions, the media and religious institutions can play a vital role. It is essential to provide civic education in order to train the younger generations of a society. In Pakistan, the education system needs to transform its practices. Teaching and learning material regarding cleanliness and hygiene should be included in the curriculum and textbooks. Educational institutions should demonstrate cleanliness in their premises. To train young people schools should involve students in cleaning their schools, homes and environment and highlight proper sanitary practices. The use of dustbins should be strictly followed in the school premises. Secondly, the media can be a powerful source to educate and sensitise the masses about the importance of cleanliness and disadvantages of an unhygienic way of life. It should focus on both the good as well as unhygienic practices in our society. Thirdly, religious institutions such as mosques and madressahs can also play their part in educating the people about the importance of cleanliness in the light of Islamic teachings. Furthermore, the role and commitment of the government cannot be overlooked in maintaining cleanliness and hygiene in society. The government’s will is very crucial in making policies and implementing them at the grass-roots level. The government can play an important role in cleaning areas, installing dustbins, collecting garbage and enforcing laws against littering etc. The importance of cleanliness cannot be ignored in individual as well as communal life. On one hand it is an important factor for human health and spiritual development; on the other hand it is essential for environmental development. By adopting a clean and hygienic lifestyle, a valuable amount can also be saved where health issues are concerned. A clean and healthy life helps in refining the culture of a society and reflects in every aspect of life such as art, architecture, food, music and so on. Ultimately, it leads towards a higher level of civilization. Islam has put unique emphasis on the importance of cleanliness by making it a part of faith. Hence, there is a dire need to make conscious efforts in educating the people about the importance of cleanliness. In this regard, serious steps are required at multiple levels to make this precious value of our faith part of our individual and collective lives.

Laptop buying guide * CNET UK * Reviews * Computers * Laptops Laptop buying guide Computers If you believe the headlines, the first rule about buying a laptop today is to forget about buying a laptop today. These bloated, annoying, space-hogging gadgets are apparently painfully obsolete compared to modern, sleek and sexy tablet computers. But just hold on a minute! Laptops still outsell tablets four to one, and sales in 2012 are expected to top a quarter of a billion worldwide for the first time ever. Laptops are faster and more powerful than tablets, have convenient full-size keyboards, are easy to connect to printers and cameras, and can glide between work and games in a flash. (Plus they can all actually run Flash. ) If you want an affordable, practical digital all-rounder, laptops come in an array of shapes, colours and prices that make flat, grey tablets look boringly identikit. There are laptops for students, laptops for artists, even laptops for mountain climbers. The only drawback to this variety is that it can be all too easy to end up with a computer that’s either underpowered or overpriced for your needs. First things first You’ll need two things when shopping for a laptop: a clear idea of what you want to do with it; and a firm budget. The good news is that all new laptops ill be fine for checking email, surfing the Web wirelessly, working on office documents, and enjoying your photo and music collections. Where things start to get trickier is if you†™re heavily into gaming, want to watch (or edit) HD video or need a computer that works well away from power sockets or in extreme conditions. Fix a budget before you start browsing — although leave a little wriggle room for extras like a laptop sleeve, software, a separate mouse and possibly an external hard drive. The basics Laptops come in three categories. At the small and portable end are ultra-lights, designed for stressed-out executives formatting Excel spreadsheets on the Heathrow Express. Not to be confused with budget netbooks (we have a whole buying guide just for them), ultra-lights tend to be nicely designed, a little sluggish and shockingly expensive. Their screen sizes range from around 11. 5 inches to 13 inches. The next step up is everyday laptop computers, sometimes called notebooks, with screens from 13 inches to 15 inches. This is the sweet shop for laptops, where the most are sold and prices are keenest. Notebooks are light enough to carry occasionally and can usually manage half a day’s work away from power, but budget ones often lack style, speed and build quality. The final category is multimedia (or desktop replacement) laptops. These monsters have screens up to 17 inches (and sometimes even larger), and come packed with smart graphics cards, super-fast processors and lots of memory. They’re the first choice of gamers, graphic designers and anyone who wants the power of an old-school desktop squeezed into a portable body. Well, we say portable, but these laptops can be heavier than a case of duty-free and bulky enough to need a Business Class seat to themselves. Windows or Mac Switch on the telly and it seems that everyone using a computer has an Apple Mac, except perhaps those hardcore hackers you see surrounded by monitors, empty pizza boxes and Star Wars figurines. In real life, however, the choice is not quite so clear-cut. Macs are built well and age slowly but cost at least two to three times as much as the cheapest Windows machines. Even at those prices, the most affordable MacBooks have cramped screens and some performance limitations. Windows computers offer more choice and lower prices, but you’ll need to stay on top of upgrades and security to get the best from them. When shopping for a PC laptop, insist on Windows 7 software. It doesn’t really matter which version, although anything running the Starter Edition is actually a netbook rather than a laptop — hop over to our netbook buying guide for more info. A bigger decision is what brand to buy. Unlike desktops, where even no-name companies can make great computers, the technical challenge of squeezing hundreds of components into a tiny case favours multinationals. Stick with top electronics brands (such as Sony, Samsung, Panasonic and Toshiba) or laptop specialists (Acer, Asus, HP/Compaq, Dell). Some retail chains also have ‘in-house’ brands that can be good value, if a bit plasticky. Tech specs Laptop specifications change all the time and consist of a brain-melting alphabet soup of letters and numbers. In general, there are three things to consider: the processor; memory (RAM); and storage. You can ask about other key components, like the graphics card and graphics memory, but don’t expect to understand the answer — check the model online if this is important to you. Processors are virtually all dual-core these days, and are usually made by either Intel or AMD. There’s little to choose between the two, although AMD silicon tends to be found in cheaper machines. Intel chips get more powerful as their model number increases (ie. an Intel Core i5 chip is faster than an Intel Core i3). Processor speed, quoted in GHz, affects how fast it can crunch numbers. Anything above 2GHz is fine for everyday use, but gamers and video fiends should look for higher numbers, and especially for Intel’s Turbo Boost feature. RAM is the other thing that affects how fast your laptop runs. 2GB is an absolute minimum these days — and step up to 4GB (or even 6GB) if you can possibly afford it. Hard decisions Hard drives generally range between 250GB (miserly) to 1,000GB (1TB, gargantuan). These determine how much data, including music and video, you can store on your laptop. Always buy a little more storage than you think you’ll need, but don’t bankrupt yourself. External drives are getting cheaper all the time, and space-saving cloud services are increasingly popular. Apple’s MacBook Airs, and some high-end Windows laptops, have fancy solid state drives that are faster, tougher and use less power. They’re also achingly expensive and come in smaller capacities. Screen and build quality Always try to get your hands on a laptop before you buy. Start by looking at the screen indoors and — if possible — near a window or outside. You’ll probably find that Apple and Sony screens have the brightest colours and best contrast. If you do have to buy from the specs alone, look for LED backlighting and Full HD for the best resolution, found on pricier machines. ‘3D’ is a buzzword right now and 3D laptops are already trickling out. While games and films can look stunning in 3D, the technology is still fairly young, fairly expensive and suffers from low levels of brightness and sharpness. Consume at your own risk. Don’t underestimate the importance of a good keyboard, trackpad or navigation nipple. Look for dedicated keys for mail, Web and especially media controls — they all make smaller keyboards easier to use. Open and shut the case a few times and hold it in both hands. How heavy is it? Does it flex or creak? How strong does it feel? While it’s hard to beat Apple for solidity and design, all the big brands have premium metal-bodied models, and Panasonic even has fully waterproof and toughened Toughbooks. In and out The best laptops have a choice of connectors, including multiple full-speed USB ports, HDMI sockets for linking to media systems and memory card readers. Some laptops will have DVD or even Blu-ray players, although these add weight and suck power. A built-in webcam is great for Skype, Facebook or FaceTime video calls — don’t worry about its resolution. Spare a thought for the battery powering all this techno wizardry. Manufacturers’ battery life figures are a rough guide, but take them with a pinch of salt and don’t expect to achieve day-long use without resorting to a socket. If you simply must have mobile freedom, choose a laptop with a replaceable battery and buy a spare immediately — they can be hard to find a year or two down the road. Ultrabooks Finally, keep an eye out for ‘ultrabooks’, a new term coined by Intel to describe ultra-thin PC laptops rivalling the MacBook Air. Expect machined etal cases, solid state drives and even touchscreen displays to make the most of new finger-friendly Windows 8. You can read our reviews of some of the first ultrabooks, including the Asus Zenbook UX21, the Toshiba Portege Z830 and the Acer Aspire S3. From G.

NATARAJAN) CLEANLINESS Introduction: Cleanliness is one of the good qualities. It is a part of our civilization. A man of dirty habits is far from civilization. So, with the progress of civilization man cleans himself more and more. He cleans his body. He cleans his mind and heart. He cleans all his action and manners. he cleans his soul. This will lead him to the highest form of civilization. But on the cleanliness of body, depend all other cleanings. Hence, cleanliness is considered so important.
