			<content:encoded><![CDATA[<p>Mana, a tiny village near Badrinath (State Uttarachal, India), is located just few meters inside the Indo-Tibet border in the Himalayas. This village, referred to as the last village of India on the Indo-Tibet border, has been designated as a ‘tourism village’ by the Uttarakhand government.</p>
<p>With 10,248 ft above sea, Mana village holds a lot of mythological relevance and we can actually see traces of the Mahabharata scattered across this small village.</p>
<p>On the top of hill at Mana, the air is more rarified and it is difficult to breath as well. There is a board announcing ‘India’s last tea shop’, stands distinctly with a neat crowd of tourists mingling about. Chand, the owner of hotel, welcomes all with smile and a cup of tea. He always says “Take this tulsi tea. In the Himalayas tulsi is available in plenty”.</p>
<p>You can have a view of border road on the one side and Himalayas on the other side. From here, there is no other way to go!</p>

			<content:encoded><![CDATA[<p>The influenza A virus is divided into subtypes, such as H1N1. The letters H and N refer to <strong>hemagglutinin</strong> and <strong>Neuraminidase</strong>. Hemagglutinin and neuraminidase are antigens, proteins that provoke an immune response in the human body.</p>
<p>There are <strong>16</strong> known hemagglutinin subtypes for influenza A (H1 to H16) and <strong>9</strong> known neuraminidase subtypes (N1 to N9). Each of these subtypes is vulnerable to a similar type of antibody.</p>
<p>There are three hemagglutinin subtypes that are known to attack human cells: H1, H2, and H3. These three subtypes bind with cells in the human respiratory tract. Other hemagglutinin subtypes target different mammals or birds. H5, for example, attacks the digestive tracts of birds. Of the nine neuraminidase subtypes, N1 and N2 are most commonly found in humans.</p>
<p><span style="text-decoration:underline;">Attack of <strong>H </strong>and <strong>N</strong></span><strong>:- </strong>Each viral particle is covered with hemagglutinin and neuraminidase. Hemagglutinin binds to the targeted host cell and injects the virus&#8217;s genetic material into it. After the virus has reproduced inside the host cell, neuraminidase releases the offspring. The host cell then dies<strong><br />

			<content:encoded><![CDATA[<p>Another wonderful project from GNU, the GSL library for mathematics !!!<br />
GSL is a numerical library written in C that provides a wide range of mathematical routines, that the C/C++ developers can make use of, to implement or design a nice platform for mathematicians. There are many such libraries available in Python (NumPy or SciPy), Java (JMSL, JavaNumerics, JNL), Perl (PDL). But GSL comes with over 1000 functions and an extensive test suite for beginners.</p>
<p>My dream was to utilize this API to build all-in-one suite for mathematics world. That&#8217;s I&#8217;m with <strong>ScientificX</strong>, one of my dream project which is currently in progress.</p>

			<content:encoded><![CDATA[<p>If you wish to create your service daemon in linux box, try the following tips:</p>
<p>1) The existing services are managed by shell scripts located in <strong>/etc/init.d directory</strong>. You can use any of this as a template file to build a service script.<br />
2) You may notice &#8220;case&#8221; blocks in the script to handle start/stop/restart/status operations.</p>
<p><strong>For Eg:</strong></p>
<p><code>case "$1" in<br />
  start)<br />
    echo -n $"Starting  name: "<br />
    echo</p>
<p>    echo<br />
    ;;<br />
</code></p>
<p>The above block will be executed when somebody try</p>
<p><code>$service  start</code></p>
<p>command. Similarly you can put &#8220;<strong>stop</strong>&#8221; or &#8220;<strong>restart</strong>&#8221; blocks as well.</p>
<p>You can <a href="http://praveenrs.files.wordpress.com/2010/12/service_script_template.pdf">download this template file</a> start building !!</p>

			<content:encoded><![CDATA[<p>The Mayavi <em>project</em> includes two related <em>packages</em> for 3-dimensional visualization:</p>
<ul>
<li><strong><a href="http://code.enthought.com/projects/mayavi/#Mayavi2">Mayavi2</a></strong>:  A tool for <strong>easy and interactive</strong> visualization of data, with  <strong>seamless integration with Python scientific libraries</strong>.</li>
<li><strong><a href="http://code.enthought.com/projects/mayavi/#TVTK">TVTK</a></strong>:  A Traits-based wrapper for the Visualization Toolkit, a popular  open-source visualization library.</li>
</ul>
<p>These libraries operate at different levels of abstraction. TVTK  manipulates visualization objects, while Mayavi2 lets you operate on  your data, and then see the results. Most users either use the Mayavi  user interface or program to its scripting interface; you probably don&#8217;t  need to interact with TVTK unless you want to create a new Mayavi  module.</p>

			<content:encoded><![CDATA[<p>Galaxy is a python based &#8220;framework&#8221; for bioinformatics, that enables communication between Experimental Biologists and Computational Biologists. It&#8217;s very easy to configure and set-up, also you can define the analysis tools to be incorporated, etc so that that it would act as a complete computational tool for biologists.</p>
<p>Galaxy aims to be a zero configuration entirely self-contained system that provides a <em>lightweight webserver</em>, an <em>embedded database</em> and a <em>multi-threaded job manager</em>. All tools (and their parameters) can be specified via simple XML based configuration files. <a href="http://g2.trac.bx.psu.edu/wiki" target="_blank">more&#8230;</a></p>

			<content:encoded><![CDATA[<p>The Open Source movement is infectious, it seems. It has bubbled up in the field of bioinformatics &#8211; gene research software. The number of open source software kits are coming day by day with a lot of enhancements in terms of accuracy, better interpretation of results, one-step analysis workbench, design own experiment with pipeline concept, advanced graphical implementation and more. If you see an amazing collection of tools for Bioinformatics in sourceForge.net, which is one of the largest open source software repository available today. More than 2090 open source tools are available at this moment;<br />
