A naturally occurring hemolysin (HL) was detected in the serum of the hermit crab Clibanarius longitarsus using mammalian RBC as indicator cells. The serum gave the highest HL titer with rabbit RBC. Cross adsorption of C. longitarsus serum with fixed rabbit RBC resulted in the complete removal of the lytic activity from the serum. The hemolytic activity in the serum of C. longitarsus was independent of divalent cations, reversibly sensitive to EDTA, thermolabile, stable between the pH 6-8. Further studies demonstrated that the HL activity is proteinaceous as it was precipitable by conventional deproteinizing agents and susceptible to the action of proteases and 2-mercapthoethanol. The HL-inhibition assay performed with several carbohydrates (mono, di, oligo, polysaccharides and Lipo polysaccharides) revealed that the serum HL was capable of specifically recognizing laminarin (a homopolymer of β 1, 3-glucan). Thus this hemolysin appears to be unique among all the known crustacean hemolysins.Keywords

This paper presents two criteria for evaluating the motoring operations of switched reluctance hub motor (SRM) drives for electric vehicles (EVs). They imply motoring torque and copper loss. To fulfil the best motoring operation, by using two weight factors and two base values, the developed optimization function selected as the correct balance between the maximum average torque and the maximum average torque per copper loss. The stator and rotor pole arc angles are selected as the optimized variables. Simulations results have demonstrated the proposed optimal design method. Therefore, this paper offers a valuable and feasible approach for implementing the best motoring operation of SR Hub Motor drives for EVs.Keywords

1. TERM-FINANCE — Its Function in the Capital Market
Industry requires financial resources for: (1) setting up a new industrial concern, (2) expansion, modernization, renovation, etc, of an existing unit, and (3) carrying out the day-to-day business operations, Finance is required for the first two purposes on a long-term basis for the acquisition of fixed assets like land, building, plant, machinery, etc. On the other hand working capital is required for financing current assets like stock of raw materials, semi-finished goods, stores, bills receivable, etc.

This paper is an attempt to study the structure and content of the Economics Courses adopted in the Indian Universities. It includes a note on internal assessment and grading of standards, as the examination system helps to indicate standards expected from student. The study is based on information relating to M.A. and B.A, courses of 30 universities and Pre-Degree or Pre-University courses of 23 universities. Though the universities studied here number less than half the total number of universities in India, they are quite representative in the sense that they cover all the states and consist of old and new ones.- Android Based Performance Assessment System for School Education

Primary and secondary school education plays important role in the knowledge development of any country. In India, government schools gaining less admission due to the infrastructure and quality of education. There are many proactive methods taken by the government to ensure that the school education empowers the students in the knowledge acquisition. Performance assessment of the schools, teachers and students is required at the periodic interval to validate the quality of the education. Also, school education department requires multi-dimensional reports of the school, staff and students for the allocation of funds and implementation of different schemes. Currently, these reports are prepared manually in paper format and communicated to the district offices. It is time consuming as well as requires man effort. This paper proposes an android based performance assessment system by which the details can be collected through android mobiles/tablets and stores in the server. Web based system is also facilitated to the schools to input the details whenever required. It helps the school education department to extract the data at anytime, anywhere. Also, this system reduces the time and effort of the staff in manual preparation. The results are evaluated for the effectiveness and found that android based mobile application gives good results.

Hyaluronic acid (HA) is non-sulphated, linear glycosaminoglycans (GAGs) extensively used in biomedical, cosmetic and nutraceutical field. This type of GAGs has created a more attraction to biologists for exploration of HA from various sources. Consequently, this present study was focused towards the marine mollusk for alternative source target for the isolation of HA from the gastropod-Hemifusus cochlidium. The whole body tissues were defatted by acetone and pellet was extracted using digestion buffer followed by proteolytic treatment. Then the crude GAGs were subjected to anion exchange column for purification. Further, HA, D-glucuronic acid and N-acetyl glucosamine content was measured using the calorimetric method. Fourier transform infrared spectroscopy (FTIR) and Nuclear magnetic resonance (H1 NMR) were used for characterization. The yield from H. cochlidium and the presence of functional group in the isolated HA was characterized by (FTIR) and H1 NMR. In this investigation, the results suggested that marine gastropod could be an alternative source of HA.Keywords
