Why laptop is better than desktop computer?

A laptop computer is completely portable

Portability is often the main advantage of choosing a laptop over a desktop computer. Portability means that a laptop can be used virtually anywhere, not only at home and the office, but also during commuting, in lecture halls, coffee shops, libraries or in meeting rooms to assist with presentations.

You can use your time more efficiently with a laptop

A laptop can be used in places where a desktop PC can't which means you can use your time more productively. For example, office workers can tackle emails during the commute to the office with a laptop at hand and students can work on coursework at the university coffee shop during a break between lectures. If you work from home then a laptop computer allows you to move your office outside on sunny days.

You can gain immediate access to information

Carrying a laptop means having instant access to information, whether it's from saved files or from the Internet. Immediacy allows better collaboration between co-workers or students, as a laptop computer can be flipped open to find a solution anytime, anywhere. If you are in a meeting and have forgotten an important document you can simply access it from your laptop computer.

Laptops are a manageable size

Laptop computers are smaller than standard PCs which is great when space is at a minimum. When not in use, a laptop can be closed and put away in a small space unlike standard PCs that tend to dominate a large proportion of a room.

Low power consumption

A laptop computer is more power-efficient than a desktop. This is beneficial for businesses (which run hundreds of personal computers, multiplying the potential savings) and homes where there is a computer running constantly. You could even save money on your electricity bill if you choose a laptop computer over a desktop PC.

Peace and quiet

It can be distracting to work at a computer with a droning fan or one that sounds like it's taking off every time you open a file. A laptop computer is often quieter than a desktop PC, due to better components and less heat production. This means cooling fans can be run at a slower speed and less often, giving you a quieter working environment.

Battery power

A fully charged laptop computer can run for several hours off its internal battery. This is useful for journeys but is also handy if there's a power cut and you still need to get work done.

A laptop computer is a great investment whether you require a computer for work or for pleasure.

Trees benefit from radiant heat and nutrients in urban areas

Many people view urban areas as hostile for plants – concrete stifles root growth, and pollution from vehicles makes it difficult to gain nutrients. A study conducted by The Earth Institute at Columbia University not only discredits those theories, however, but suggests that urban environments have a lot to offer plants to promote growth.

To conduct the research, The Earth Institute researchers planted seedlings in the spring of 2007 and 2008 in three sites around New York. Those locations included an area in northeastern Central Park, near 105th street; in two forest plots in the suburban Hudson Valley; and in more rural surroundings near the Ashokan Reservoir in the Catskill foothills, about 100 miles (161 km) north of Manhattan. Over a five-year period, researchers observed an eight-fold increase in biomass in the urban-grown seedlings.

Researchers attribute the increased growth to high temperatures (particularly at night), carbon dioxide concentrations and atmospheric nitrogen deposition. Saplings planted in Central Park developed a lower root-to-shoot ratio, which reduced below-ground carbon costs to the plant. To compensate for the root development, urban seedlings allocated more growth to leaves than the rural-grown seedlings. This resulted in a ten-fold greater photosynthetic area but the same photosynthetic capacity of foliage as the rural plants.

The findings mark a step toward understanding how nature and urban environments mix. "With human influence spreading across the globe, nature and urban environments are inseparable. The key is that plants can adapt to these changes in their environments, and in this case, really thrive in a human environment," said Stephanie Searle, lead author on a report of the study. Searle is currently a researcher at the International Council on Clean Transportation in Washington DC.

The report's authors weren't surprised by the results. "Our hypothesis was that the oak seedlings would grow faster in the city due to the higher nighttime temperatures," said Searle. Two previous studies on growth of poplar trees in Biosphere 2 conducted by Principle Investigator Kevin Griffin and co-author Matthew Turnbull, plus a previous study on poplar growth in urban environments by Jill Gregg, laid the groundwork.

The research did uncover new findings, however. "We were surprised at the magnitude of difference in growth between trees at the urban versus rural sites," Searle said. "Also, we had hypothesized that the urban seedlings would grow faster specifically because of their higher photosynthetic capacity boosted by higher temperatures, and this turned out not to be true; these plants got a head start by simply investing more resources in the leaves rather than roots compared to the rural plants."

While the findings reinforce the importance and potential of trees and other plantings in urban environments, many cities including New York City already make great efforts to create green spaces. Central park's 843 acres (341 hectares) are landscaped with trees, though many were knocked down in severe lightening storms in the summer of 2009.

"We believe that the 'urban heat island' effect may help trees in the city grow faster and thrive, but most trees in New York City are planted, so the fact that there are so many trees is really thanks to a great job by the NYC Department of Parks and Recreation," Searle commented.

Now it's up to New York City – as well as other urban areas – to capitalize on the advantages of tree growth, and keep cities green.

The paper on the research was recently published in the journal Tree Physiology.

2. Melon Fruit as Anti-cancer
   Melon fruit contains high carotenoid that this fruit can prevent cancer and reduce the risk of lung cancer. Melon fruit can prevent and kill cancer seeds that will invade our bodies. So try to avoid eating melon cancer.
3. Melon Fruit as Anti stroke / heart
   Melon contains an anticoagulant called adenosine to stop clotting of blood cells which can lead to stroke or heart disease. So the melons will help smooth the blood in the body so that a small risk of stroke or heart disease incidence.
4. Melon Fruit for Relieves heartburn.
   Water levels on melon fruit reached 95%, giving the effect that menyejukkan.Karena, melons can be useful to relieve heartburn.
5. Melon Fruit for Smooth CHAPTER
   Melons can launch BAB (big water baung) when we have digestive problems then eat melon to be easy and smooth bowel movement. Water content in the melon is very good for digestion. Mineral content is able to eliminate the acidity of the body need to be eliminated because it can interfere with digestion, particularly in the stomach organ.
6. Melon fruit helps heal kidney disease and eczema.
   Melon has a very good diuretic power so that it can help cure kidney disease and severe eczema and akut.Jika combined with lemon, melon can suppress the disease gout.
