Internet In Nepal

Internet Is the global network connecting millions of computers. More than 100 of countries are linked into exchanging data, news and openions through internet. Same like other countries, Nepal is also the one of the country. Although through 2010 less than 45% of Nepals population use internet. User's of internet in Nepal is increasing rapidly. It is due to the ISP (Internet Service Provider) market and low prices.
             As in other countries Internet is use as the source of news, informations and exchanging data in Nepal. Lots of FM, TV and newspapers all the medias and even in the case of business internet is useful to us.
           Simply people learn to use internet as the intertainment. Unknowingly they became the victim of cyber crime too. In case of Nepal there are no more cyber law active. So it is easy to do such crimes through internet. As the people are less educated about using internet safely. In case of Nepal, most of the areas are remote. So due to many reasons the couldnot learn about the internet, or may they couldnot have the chance to learn how to use internet.
               Nowadays a lot of Intenet Service Providers are available. Such as Broadlink, ADSL etc. but the service providers are limited only in developed areas. In case of remote area no such Providers are available, or it may they couldnot provide their service due to alot of reasons and technical errors. People in Nepal can use internet through the mobile sim cards too. Nepal Telecom and NCELL users can use internet sercive in their cell too. It depends upon the type of SIM card and Mobile Set. Nowadays Telecom Companies bring alot of offers in case of Mobile Internet. It is the part of business.
As the users of internet is increasing day by day we need to be aware from the mis use of internet. We should know how to use internet safely and how to utilize. So before using internet and before going through website we should know what to do and what not to do. One more important thing is the cyber laws should be followed. Being as a Nepali citizenship and also being as a human being we should avoid the misbehaves and misuses of internet. Because internet is very useful to us as well it may harm us very badly.

The Value Of Chemistry

Chemical research has traditionally been organized in either experiment-centric or molecule-centric models. This makes sense from the chemist's standpoint. When we think about doing chemistry, we conceptualize experiments as the fundamental unit of progress. This is reflected in the laboratory notebook, where each page is an experiment, with an objective, a procedure, the results, their analysis and a final conclusion optimally directly answering the stated objective. When we think about searching for chemistry, we generally imagine molecules and transformations. This is reflected in the search engines that are available to chemists, with most allowing at least the drawing or representation of a single molecule or class of molecules (via substructure searching). But these are not the only perspectives possible.What would chemistry look like from a results-centric view? Lets see with a specific example. Take EXP150, where we are trying to synthesize a Ugi product as a potential anti-malarial agentand identify Ugi products that crystallize from their reaction mixture. If we extract the information contained here based on individual results, something very interesting happens. By using some standard representation for actions we can come up with something that looks like it should be machine readable without much difficulty:
  • ADD container (type=one dram screwcap vial)
  • ADD methanol (InChIKey=OKKJLVBELUTLKV-UHFFFAOYAX, volume=1 ml)
  • WAIT (time=15 min)
  • ADD benzylamine (InChIKey=WGQKYBSKWIADBV-UHFFFAOYAL, volume=54.6 ul)
  • VORTEX (time=15 s)
  • WAIT (time=4 min)
  • ADD phenanthrene-9-carboxaldehyde (InChIKey=QECIGCMPORCORE-UHFFFAOYAE, mass=103.1 mg)
  • VORTEX (time=4 min)
  • WAIT (time=22 min)
  • ADD crotonic acid (InChIKey=LDHQCZJRKDOVOX-JSWHHWTPCJ, mass=43.0 mg)
  • VORTEX (time=30 s)
  • WAIT (time=14 min)
  • ADD tert-butyl isocyanide (InChIKey=FAGLEPBREOXSAC-UHFFFAOYAL, volume=56.5 ul)
  • VORTEX (time=5.5 min)
