PhD opportunity for Nepalese

Tweet

We are lacking of equipment, funds, opportunity, and the policy makers who had never try to understand the value of science so that we have no reputation despite our honesty and laborious work. But we have strong theoretical background in TU and other Universities of Nepal due to tough syllabi/syllabuses  and competition. Erasmus Mundus Europe Asia (EMEA) scholarship has given high priority for Nepalese, and offering full-funded MS, PhD and post-doc positions in different universities of Europe. Nepali passport bearer who completed MSc or 4-year BSc are eligible to apply. Probably, stipend will be 1000-1600 Euro/month. Dead line is December 1, 2011.

Update Mendeley, Reference Managing Software

Tweet

Due to different styles of references for thesis or articles to be submitted in different journals or departments, reference managing software is exigent nowadays. Mendeley is a freely available reference managing software, which is the most suitable for Linux user, however, Windows user can also use it. Endnote is another good option for Windows user but we have to pay for license.
        Full version of Mendeley 1.1.3 was released few months ago, download from here.

1. Extract to your suitable folder e.g., to /media/sda5/softwares
2. Run by clicking icon "mendeleydesktop" on the location of /media/sda5/softwares/mendeleydesktop-1.1.3-linux-i486/bin
3. Go to "tools" and "Install OpenOffice Plugin" or "Install LibreOffice Plugin" (if you see the message "it won't find "unopkg" in its default location...................... or something like this" then, locate towards /opt/libreoffice/program and click "unopkg" )
4. Click on "Add Documents" and locate any one PDF and add
5. Open "LibreOffice Writer" or "OpenOfficeOrg writer" (equivalent of MS Word) and write something
6. Click "Insert Citation" then go to Mendeley Desktop and click the PDF in the document section just you have added (BibTex or other format can be added)
7. Click "send citation to word processor"
8. Then go to word file and click "insert bibliography"

Cannot Nobel prize be awarded for Windows OS, Google or Facebook ?

Tweet

Announcement of Nobel prize soothed pounding of many people. Although no Nepali has been awarded, Nobel prize is the subject in the gossip of literate Nepali. Nobel prize has been becoming the dream and destination not only for scientists but also for politicians, economists, writers and so on. Nobel prize is intended for new discovery, or significant contributor who made life easier and well organized society.

The first step in the discovery of theory or science is the designing of research through literature search. Some search engines certainly have signified and accelerated in this process. There are many search engines, and Google is the widely used and popular. Google search engine script was discovered by Larry Page and Sergey Brin as PhD candidates at Stanford University. 

Analysis and data interpretation of research and experiments needs software for promptness and accuracy. The software needs good platform to be installed. Bill Gates and his colleagues had discovered and developed the popular operating system (OS), DOS, Windows. Mac OS, Unix, Linux, FreeBSD, etc. are the other OS, but still they  are not as popular, and easier as Windows OS. In addition, Microsoft has developed the office packages (Word, Excel, PowerPoint, etc.), which are also essential in research. Nobel prize in Physics has been awarded for research of hard disk miniaturization (2007), and development of integrated circuits (2000), which are essential part of computer hardware. I think, Software developer also has the similar type of contribution and deserves for the Nobel prize. 

Facebook and twitter, however, are not essential in the scientific study, but they are popular among the community and  are good medium to increase the relationship and information. And Facebook is the top web page based on the number of users everyday.

In my opinion, the famous novel, Harry Porter, Miscrosoft OS, Google, Facebook, Twitter, or their designer deserve Nobel prize in literature. Probably, there would be a policy, not to award Nobel prize who had gained popularity and money.

If Nobel prize is awarded for these computer applications, which category would be appropriate for them? Physics, due to the scripts design and engineering? Economics, as these are among top revenue generating companies? Peace,  because Facebook and Twitter had played an important role to dethrone the tyrant of Egypt and other countries. some people may think reverse of it, people agitated and involved in violence due to Facebook and Twitter.

महिलाहरुमा autoimmune रोगको सम्भावना ज्यादा हुने कारण

Tweet

चालिस बर्ष उमेरपछिको स्थिती हेर्ने हो भने, पुरुषलाई भन्दा महिलालाई auto-immune रोग लाग्ने सम्भावना तीन गुणा धेरै हुन्छ । अहिले सम्म पाइएको तथ्याङ्क अनुसार, महिला : पुरुष = ३:१ छ । मेरो लेख, Auto-immune रोग के हो त ? हालसालै गरिएको अध्य्यन अनुसार महिलाहरुमा auto-immune रोगको सम्भावना ज्यादा हुने निम्न कारणहरु पत्ता लागेका छन् ।

1. Estrogens (oestrogens) हार्मोन महिलाहरुमा उत्पादन हुन्छ भने पुरुषहरुमा testosterone हार्मोन । estrogens हार्मोनले immune system ज्यादा सकृय हुन उत्प्रेरणा दिन्छ ।
2. मानव शरीरमा २३ जोडा अनुबशिंक तत्वहरु (chromosomes) हुन्छन् । प्रत्येक जोडामा एक-बाबु तथा एक-आमाबाट आएका हुन्छन् । पुरुष र महिलामा २२ जोडा chromosome एकै किसिमका हुने भएता पनि २३ औं जोडा भने फरक हुन्छ । २३ औं जोडामा XX (महिला), XY (पुरुष)हुन्छ । यहीँ X chromosme मा immune प्रणालीलाई ज्यादा सकृय बनाउने केही रसायनहरु उत्पादन गर्ने अनुबशिंक तत्वका ईकाइहरु (genes) रहेका हुन्छन् । महिलाहरुमा X-chrosome दुइवटा हुनाले पुरुषको तुलनामा यस्ता रसायन हरु पनि दुईगुणा बढी उत्पादन हुन्छन् । हुन त gene दुईगुणा भयो भन्दैमा त्यसको उत्पादन पनि अनावश्यक रुपमा दुईगुणा नै हुन्छ भन्ने त होइन । नचाहिएको एउटा gene लाई छोपेर राख्ने र यस्को उत्पदन हुन नदिने अर्कै प्रणाली हुन्छ, यदी यो प्रणाली बेकार भएमा मात्र महिलाहरुमा autoimmune रोगको सम्भावना ज्यादा हुन्छ।
3. Microchimerism:- गर्भावस्थामा रहेको भ्रुण/बच्चा महिलाको रक्तसंचार प्रणाली सँग प्रत्यक्ष सम्पर्कमा रहेको हुँदैन, साल-नाल को माध्यमबाट अप्रत्यक्ष रुपमा संपर्कमा रहेको हुन्छ । तर, कारणबस महिलाको रक्तसंचार प्रणालीमा बच्चाको कोष, तन्तु इत्यादी आउन पुग्यो भने महिलाको Immune system सकृय भाईहाल्छ । यो सकृयता Helper CD4 T-cell ले स्मरण गरिराखेको हुन्छ जसले महिलालाई बच्चाको जन्म पश्चात पनि हानी पुर्याउँछ । सामान्यत: बच्चाको जन्म पश्चात यस्ता Helper CD4 T-cell आँफैँ नस्ट हुन्छन् ।

रोग प्रतिरोधात्मक प्रणाली ज्यादा सकृय भएर हुने रोगहरु (Autoimmune Diseases)

Tweet

हाम्रो शरीरमा बाह्य हानिकारक बस्तुहरु जस्तै: जीवाणु (bacterium), बिषाणु (virus), परजिवी (parasite) इत्यादी प्रवेश हुने बित्तिकै हाम्रो शरीरको रोग प्रतिरोधात्मक प्रणाली (Immune System) सकृय हुन्छ र रोग लाग्न दिदैन । यदि यो प्रणाली कमजोर भयो भने हाम्रो शरीर भित्र प्रवेश गर्ने जीवाणु/ बिषाणु/ परजिवीहरुले तुरुन्त आक्रमण गरिहाल्छन् र हामीलाई रोगहरु जस्तै: झाडा-पखाला, रुघा-खोकी, क्षयरोग, इत्यादी. लाग्छ ।

AIDS वास्तवमा आफैंमा कुनै रोग होइन तर यसले चाँही हाम्रो immune system लाई यती कमजोर बनाइदिन्छ कि निको नै नहुने गरी, अनी सबै किसिमको (सरुवा) रोगहरु लाग्छ र मृत्‍यु हुन्छ ।

तर immune system ज्यादा सकृय अथवा cross reaction भयो भने पनि यसले हाम्रो शरीरका आफ्नै कोष, तन्तु तथा अङ्गहरुलाई आक्रमण गर्न सुरु गर्छ अनी आँफैमा एक रोगको रुप लिन्छ, जसलाई Autoimmune Disease भनिन्छ । यसअन्तर्गत बात (Rheumatoid Arthritis), बिसमज्वर (Rheumatic fever), दम (Allergic Asthma), खास प्रकारको मुटुको रोग (Rheumatic heart disease), Graves' disease, Lupus, Optic neuritis, Pernicious anemia, Sjögren's syndrome, Primary biliary cirrhosism, Myasthenia gravis, Diabetes mellitus type 1, इत्यादी. (यस्ता सय भन्दा बढी किसिमका रोगहरु पत्ता लागेका छन्) ।

Install LibreOffice in Older Version of Fedora

Tweet

As I have been writing (can be found under labels: Linux, Fedora, Computer), Linux OS has been improving in graphical user interface and other packages/applications. OpenOffice, which is one of the powerful application/package, was the Linux equivalent of MS Office (Word, Excel, Power-point, Access, etc.). Recently, OpenOffice has been replaced by LibreOffice in Linux OS probably due to license conflict. In the latest version, Fedora 15, it can installed as;

1. Open terminal, and become root user (type "su" and then type password ".......")
2. Type "yum install libreoffice" OR type "yum groupinstall "Office/Productivity""

In older version of Fedora (bur not older than Fedora 8), we have to

1. Download all the required files here (Other options are available to select there, e.g., to install in Windows, ".exe" file can be selected).
2. Extract the zipped file (mouse-right click and click on "extract here". Careful ! where does this file situated, normally it remains under home/Downloads).
3. Open terminal, and become root user
4. Type "yum localinstall /home/bishnu/Downloads/LibO_3.3.4rc1_Linux_x86_install-rpm_en-US/RPMS/* --nogpg" (after few seconds it will ask for permission, then type "y")
5. Then again type, "rpm -Uvh  /home/bishnu/Downloads/LibO_3.3.4rc1_Linux_x86_install-rpm_en-US/RPMS/desktop-integration/libreoffice3.3-redhat-menus-3.3-401.noarch.rpm --force"

Note: Bishnu can be replaced by your username, or entire /home/bishnu/Downloads can be replaced by actual location of these file. But it will be easier, if we paste this folder (software) under /Downloads, if it was brought from friend's computer/purchased). The file names LibO_3.3.4rc1..... / libreoffice3.3-redhat-menus-3.3-401 are variable with the time.

Nepalese in Reputable Science Journals

Tweet

Probably, there might be some articles published by Nepalese in the famous and reputed science journals, such as science, nature, cell, etc.

Recently, Lujendra Ojha, Mhaipi, Kathmandu has discovered the possibilities of water in the Mars. This made him a famous scientist, and he has been covered in all types of media worldwide. He is an undergraduate research intern at lunar and planetary laboratory, University of Arizona, Tucson, USA. He published his finding as second author in one of the most famous journal (Science, 5 Aug 2011, 333 (6043); 740-743, impact factor of this journal is 31.4).

Another two Nepalese (Deepak Koirala and Soma Dhakal) have published their research article as first and second author in one of the most reputed journal (Nature Chemistry, 28 Aug 2011, impact factor of this journal is 17.9). Deepak Koirala, Rupandehi district, was the batch topper in MSc from Central Department of Chemistry (CDC), TU, Nepal.  Soma Dhakal, Palpa district, also did his MSc from CDC, TU, Nepal and recipient of university fellowship award for his outstanding performance in research from Kent State University, USA. Currently, both are pursuing their PhD from Department of Chemistry and Biochemistry and School of Biomedical Sciences, Kent State University, Kent, Ohio 44242, USA.

Their success not only inspires Nepalese but also shows Nepalese are capable, if got the opportunity. Almost all Nepali who had completed their MSc from Tribhuvan University, Nepal had been doing well in foreign. However, there is no reputation of Nepal in science. International journals usually reject if the corresponding author's affiliation is Nepal (personal experience). This is mainly due to unavailability of good equipments, no budget allocation for research and higher study. Receiving chemicals and reagents used in the laboratories are the expensive and slow process. Ministry of “science and technology” is the least preferred for any political parties and politicians. 

And those Nepali scientists who got the international reputation, should be a leader to develop  / install science and technology and research in Nepal, whatever might be our corrupted government thinks. So that all bright young and brilliant Nepali will get chance to show talent, and do something for science.

Influencing Google+ Made me Switching off Facebook

Tweet

Although I am beginner of google+, nowadays I am spending more time in it as compared to Facebook. Obviously, some exciting features of Facebook had been luring not only teenagers but also geriatrics. But some limitations such as  option to add as friend only, though all connected people are not friends. Few years ago, I had requested one of my teacher to add as a friend. He knew me. I am confident he knew me, however, he asked to introduce myself. Even though I introduced myself, he doubt as we were friends. Can't we be connected each other in Facebook because we are student and teacher? That's why I have not requested any of my teachers to connect in Facebook yet.

I was asked to introduce before connecting in Facebook but still not connected

Another limitation of Facebook was some status. It might not be appropriate for my relatives connected, but useful for my class fellow. These status couldn't be hidden from each other.I have to restrict selecting one by one. Jokes that I wanted to post, might be laughable for some of my friend of college, which is not necessarily understandable by my friends of school level.

I hope Facebook overcome these limitation within few weeks (or probably, have updated). Otherwise I prefer google+ to Facebook.

2. राजेश दाइ सानो हुँदां Staphylococcus र Streptococcus को गुच्चा खेल्नुहुन्थ्यो रे ।
3. राजेश दाइ सानो हुँदां Escherichia coli र  Vibrio cholera को डण्डीबियो  खेल्नुहुन्थ्यो रे ।  एकदिन, E. coli डण्डीले V. cholera गुलीलाई अलि जोडले हिर्काउनुभएछ, त्यसैले आजसम्म पनि V. cholera बाङ्गोको बाङ्गै छ । 
4. HIV त राजेश दाइसँग डराएर पो रहेछ, CD4 T-cell भित्र लुकि-लुकी बस्ने । 
5. राजेश दाइको लामो कपाल देखेर पो Salmonella typhi पनि peritrichous (झुसे) भएको रहेछ ।
6. २०५१ सालमा नेपालमा ठुलो खडेरी परेको थियो, किन भनेर बुझ्दै जांदा त राजेश दाइले Agaricus biospora (mushroom) को छाता बनाएर ओढ्नु भएको रहेछ ।
7. राजेश दाइले एउटा भुस्याहा कुकुरलाई गोली हान्नु भएछ, गोली लाग्यो, घाऊ-रगत देखिएन, तर पानी देखी डराउने मात्र भएछ, १४ दिनपछी बल्ल कुकुर मरेछ । यसपल्ट त राजेश दाइपनि अचम्म पर्नुभएछ । (Bullet shaped Rhabdovirus).
8. राजेश दाइको 'देउता' चलचित्र हेरेपछि Proteus त एकै ठाउँमा बस्न नसक्ने चकचके भएछ । (Swarming motility of Proteus spp.)
