Intellectual Capital: A Case Study of Power Loom Using Analytic Hierarchy Process: The purpose of this paper is to identify the critical success factors of IC influencing the performance of power loom textiles, to evaluate their impact on the organizational performance and to find out the effect of these factors on the organizational performance of small and medium-sized enterprises (SMEs) in Maharashtra using AHP. The methodology adopted is factors are identified through the literature survey and finalization of these factors is done by taking the opinion of Experts in the Indian context. By cognitive map the relation between these factors is determined and cause and effect diagram is prepared. Then these factors are arranged hierarchically and tree diagram is prepared. A questionnaire was designed and distributed among the experts; data is collected. By using Expert choice software data is filled to quantify by pair wise comparison of these factors and are prioritized. The weights demonstrate several key findings: local and global priority reveals there is a substantial effect of the Human capital on the organizational performance. The work related experience contributes 34.21%, which has a greater impact on performance. Operational procedures or practices contribute 52% in order to improve the operational performance and hence organizational performance. Overall, the results showed the central role of the human capital is important. The research is subject to the normal limitations of AHP. The study is using perceptual data provided by Experts which may not provide clear measures of impact factors. However, this can be overcome using more experts to collect data in future studies. Interestingly, the findings here may be generalisable outside Maharashtra, India. AHP as an innovative tool for quantification of IC factors impacting on performance and improving operational and organizational performance in today’s dynamic manufacturing environment. The finding suggests the notion that these IC critical success factors (CSFs) are to be studied carefully and improvement strategy should be developed. Moreover, the study emphasizes the need to link priority of factors to organizational performance and improvement. The study integrates the CSFs of performance and its quantification by using AHP and its effect on performance of power loom textiles. Very few studies have been performed to investigate and understand this issue. Therefore, the research can make a useful contribution.

Effect of Node Movement on DSDV, AODV and DSR: A Mobile Ad-Hoc Network (MANET) is a self-configuring network of mobile nodes connected by wireless links to form an arbitrary topology without the use of existing infrastructure. Each node participating in the network acts both as host and a router and must therefore is willing to forward packets for other nodes. Research in this area is mostly simulation based; Random waypoint is the commonly used mobility model in these simulations. In this paper we have compared the performance of DSDV, AODV and DSR for different node speeds. Experiment results illustrate that performance of the routing protocol varies across mobility and node density.
Some researchers in the infancy stage of their careers seldom bother about impact factors, citable content and metrics such as i-index or h-index. All they need is some clarity on how the subject is going to impact their scope of work. Indexing the citations is no longer a prerogative of the statisticians because it is actually the authors and researchers who are responsible for producing citable manuscripts. Prolific writers do not need a mention as to what they need to do in order to produce citable literature. They understand the parameters that govern high quality content. The race for citation indices is now interesting. Apart from h-index by Hirsch, the g-index by Leo Egghe, we have the latest arrival……….

A Survey of Positivity to 4-Aminoquinoline among Primary, Post Primary and Tertiary Institution Students in Ado Ekiti, Ekiti State, Nigeria: A survey of urine positivity to 4-aminoquinoline was carried out to examine the current status of the chloroquine in the treatment of malaria in Southwestern, Nigeria. Out of 352 students examined 352(61%) were positive using Dill-Glazko test. High occurrence was more among the primary school pupils (68%), than secondary (62%), and tertiary (47%). More female student (61%) used chloroquine than male (55%). Pupils in the age group 6-10years (26%) had the highest occurrence followed by 11-15years (16%), 16-20years (8%), 21-25years (5%), 1-5years (3%) and 26-30years (1%) respectively. Although, newer antimalarial drugs such as Atesunate/Arthemeter, Halofantrin etc have been introduced lately, more people in Ado-Ekiti still prefer Chloroquine for the treatment of malaria. This result of the study suggests that chloroquine is still the first line of drug for the treatment of malaria in Ekiti state, Southwestern Nigeria.

Anthelmintic Screening of Crude Extracts of Hygrocybe Parvula: The World Health Organization estimates that a staggering two billion people harbor parasitic worm infections. Parasitic worms also infect livestock and crops, affecting food production with a resultant economic impact. Despite this prevalence of parasitic infections, the research on anthelmintic drug is poor. As per WHO, only few drugs are frequently used in the treatment of helminthes in human beings. Anthelmintic from the natural sources may play a key role in the treatment of this parasitic infections.In the present investigation, anthelmintic screening of crude extracts of Hygrocybe parvula. The present study aimed at the in-vitro evaluation of anthelmintic activity of various solvent extracts of fruiting bodies of H. parvula using at three different concentrations (25, 50 and 100mg/ml) respectively. The study involved the determination of time of paralysis (P) and time of death (D) of the worms. In view of this petroleum ether, chloroform and methanol extracts of fruiting bodies of H. parvula were evaluated separately for the activity on adult Indian earthworms, Pheretima posthuma, using Piperazine citrate as reference standards. The results indicated that the petroleum ether extract was more potent than the chloroform and methanol solvent extract. All extracts showed effective anthelmintic activity at 100mg/ml concentration.

We are not wrong to say that Jeffrey Beall is publishing bluffing on his website. He has written our company name on his website. We ask him that why you have written our company name on your website… he said if I though I do. We ask him to remove our name instead of that he has written a note on his website… he is just trying to create problems for upcoming journals… We had also sent one of the recent review report on his mail id and ask him that please give your guideline on what basis you write our company’s name but he do not have any genuine reason for the same.
A full mail communication can be given on<http://journalsclub.com/Jeffrey-Beall.pdf>
He doesn’t want us to start such service or he may be supported by other who do not want journals club in this service area.
We would like to update you that we are also not bound with this service only. We are also working to serve academic people for indexing, editing & plagiarism in the future.
Jeffery Beall does not have any documentation for writing any journal name on his website. He also don’t have guideline to remove journal name from his website.
We try a lot, but he just said if I thought fit I will write and last but not list A librarian cannot judge a journal until he has good documentation for that.
Some international people only emphasis on English language to create the value for themselves, but what we believe is that peer review process is the only important technical aspects to publish a technical documents online.
---------------------------------------------- UPDATES ---------------------------------------------------------
It was always interesting how people are getting to gather to earn money may be by using direct method or maybe by using an indirect method like this. We got the following two mails saying that we will help you for proof reading services. Akim John also claims, says that I think, I will be able to contact Jeffrey Beall and request the removal of Journal Clubs & Co. From his list.
As a director of this company, I just want to say that non English speaking country like India are not handicap as far as English proofreading is a concern. We are in discussion with various recruiting agencies, and soon we will be hiring a person for the same job. We don’t like to feed international people who contact us in a wrong way like one person is posting a post on his website blog and another is coming for service help. If this such kind of silly method was not used, then we may think about to hire a service from international people or firm.
Our aim is to serve students, authors & editorial board members with best quality services. We as a technical people are much more concern about technical aspects of articles through a peer review process.
I think this website http://scholarlyoa.com/ has been created to miss guide the researcher.
