Role of insurance in the development of India’s micro, small and medium enterprise (MSMEs) / Abhijit Chakraborty and Ashim Kr Das

This paper investigates the role of Insurance in the development of Micro, Small and Medium Enterprises (MSMEs) in India. MSMEs have been accepted as a crucial component of an economy irrespective of the phase of development it is in. It is estimated that more than 95% of the enterprises across the world are MSMEs, employing around 60% people in the private sector. The MSMEs are considered key elements in the development of every nation. In India, MSME sector contributed 28.77% in GDP in 2016-17 with 63 million enterprises and employment of 110 million people. Despite its size, MSMEs cumulatively act as foundation of a stable economy and plays a significant role in the sustainable economic growth of a nation. However, the inherent features of MSMEs including limited financial and managerial capability cause them to face financial and strategic risks. Sustainability of the MSMEs can be supported by eliminating the credit gap and ensuring enhanced access to finance. The provision of financial support by financial intermediaries like banks can be augmented with proper risk management by the MSMEs with the help of Insurance Sector. The study concludes that insurance can play a significant role in the development of MSMEs by providing them adequate risk protection and thus enhancing their access to financ

Evaluation of Famous Recommender Systems: A Comparative Analysis

In this era of the internet and with the easy availability of data at a very low cost, searching for information is growing at an exponential rate. So, it is now impossible to find the desired information without proper guidance. Here is the need of the recommendation system. The system will recommend which information relevant to the user according to their searching pattern. It will also explore hidden results with a minimal effect. The goal of this paper is to describe the famous recommendation systems which are used mostly and to explore what is the need of these kinds of systems and also what kind of technology has been used to provide better services to its users. Finally we would like to show how one recommendation system is different from another as per user need

On generalizations of certain summability methods using ideals

AbstractIn this paper, following the line of Savas and Das (2011) [10], we provide a new approach to two well-known summability methods by using ideals, introduce new notions, namely, I-statistical convergence and I-lacunary statistical convergence, investigate their relationship, and make some observations about these classes

A case of bilateral acute angle closure attack with some unusual features

A 45 year old male presented with sudden severe pain, redness and marked diminution of vision in both eyes along with corneal oedema, pigmented KPs and raised IOP. After treatment with hyper osmotic agents, IOP came down and cornea became clear. Anterior chamber was shallow bilaterally with ring synechia. Gonioscopy revealed peripheral anterior synechiae in left eye and occludable angle in the right eye. Fundus examination was within normal limit. The patient was treated with antiglaucoma medications and steroid. Trabeculectomy was done in left eye with laser PI in the fellow eye. IOP came down within normal limits on subsequent visits with residual iris sphincter damage

STRUCTURAL ELUCIDATION OF BIOACTIVE SECONDARY METABOLITES FROM ENDOPHYTIC FUNGUS

Objective: In this research for bioactive secondary metabolites from endophytic fungal isolate CPR5, which was later identified and characterized as Aspergillus niger sp.Methods: Eight bioactive compounds (1-8) were isolated and purified using a series of chromatographic techniques and identified by applying 13C and 1H nuclear magnetic resonance and mass (ESI-MS spectrometry).Results: All the compounds were tested for antimicrobial activity against a wide range of human and plant pathogenic bacteria as well as fungi. These microorganisms were, Xanthomonas oryzae, Escherichia coli, Streptococcus pneumonia, Bacillus subtilis, Staphylococcus hyicus, Bacillus sphaericus, Staphylococcus aureus, and Pseudomonas aeruginosa, Candida albicans, Sclerotium rolfsii, Sclerotinia, scleratiourum, and Phoma exigua minimum inhibitory concentration value have also been determine for these microorganism.Conclusion: In this study, a total 10 endophytic fungi were isolated from the Calotropis procera, show a great antibacterial activity against 24 human pathogenic bacteria

Optimization of process parameters for production of antimicrobial metabolites by an endophytic fungus Aspergillus sp. CPR5 isolated from Calotropis procera root.

Objective:To study the antimicrobial activity of crud ethylacetate  extract from endophytic fungus in Calotropis procera root.Methods:Endophytic fungus was screened for production of antimicrobial metablites.fermentation was carried out in 500 ml Erlenmeyer flask. Disc diffusion method was used to test antimicrobial activity of crude extract using chloramphenicol sulphate and Flucnazole as positive controleRessults: A total of fourteen Endophytic fungi were isolated (CPR1- CPR14). Among these fourteen isolates, CPR5 was found to show maximum antimicrobial activity, in compare to other isolates, against gram positive, gram negative bacteria and fungi. The antimicrobial activity was tested against Escherichia coli. Pseudomonas aeroginosa, Bacillus subtilis, Staphylococcus aureus, Ralstonia solanacearum, Xanthomonas oryzae, Penicillium chrysogenum, Candida albicans, Phoma exigua, Sclerotium rolfsii and Sclerotinia scleratiourum. Minimum inhibitory concentration (MIC) of crude extract against test microorganisms was determined. Fungus was identified as aspergillus sp. Prduction parameters (Temprature, pH, Carbon source, Nitrgen surce, Sdium Chlride concentration) were optimized.Conclusion:  Crud  extract produced by the isolated endophytic fungus could be an important source of broad spectrum antimicrobial metabolites. Keywords: Endophytic fungi, Antimicrobial metabolites, Process optimization, Calotropis procera, Inhibition zone

STUDY ON THE HYDROTHERMAL GROWTH OF ZnO NANORODS FOR PIEZOTRONIC APPLICATIONS

The capability of a certain material to generate an electric charge in response to applied mechanical stress is called as piezoelectric Effect. Metal oxidesemiconductors having high piezoelectric coefficient can be cost effectively manufactured by a simple hydrothermal methods at low temperature. These nanostructures are capable of transforming mechanical deformation into electrical power. The nanostructure morphologies and dimensions can be controlled by controlling the growth conditions. When subjected to mechanical deformations, these nanostructures are capable of transforming mechanical deformation into electrical power. Due to the structural noncentralsymmetry,ZnO nanostructures exhibit anisotropic piezoelectric properties. High aspect ratio ZnO nanostructures can be merely designed using hydrothermal methods and these nanowires or nanorods show piezoelectric properties. When subjected to mechanical deformations, these nanostructures undergo a charge separation due to inherent structural asymmetry. Tapping of the separated charges and subsequent accumulation can give a manifestation of mechanical to electrical energy transformation and lead to energy harvesting
