Abstract: The use of hemicellulolytic enzymes has recently attracted considerable interest as a substitute for chlorine chemicals in pulp bleaching in view of the environmental concerns. Fungal biotechnology opens a potpourri of strains for identification and secondary metabolite extractions. The present work aims in extraction of xylanase from novel microorganism(s) for its commercial application as biobleaching agent in paper and pulp industries. Eight xylanolytic fungi were isolated for the enzyme production. The culture conditions for enzyme production were optimized. The optimal enzyme activity was assayed for the xylanse enzyme. The results of the work were discussed with related references.

Abstract: The use of hemicellulolytic enzymes has recently attracted considerable interest asa substitute for chlorine chemicals in pulp bleaching in view of the environmentalconcerns. The cellulase free xylanase from microorganisms has been isolated and testedfor bleaching activity, giving rise to a new concept of biobleaching. In this aspect, thepresent study aims to check the tolerance of Trichoderma spp., a biological controllingagent, in perceptive to the production of xylanase enzyme. The strains were isolated fromthe environmental soil samples taken from the effluent treatment area. The organismswere subjected to growth at various pH conditions. The resistant strains T-1 and T-2 to adifferent pH were further isolated and grown by on selective xylan-agar medium.Maximum growth of the organism was found at 48h under submerged condition in xylancontaining enriched medium. The organisms produce an extra cellular xylanase that had alow molecular weight and optimal working temperatures. Further proposed studiesinclude the bleaching activity of the enzymes and comparison of the industrialapplication with the commercially available enzymes. The trials can also be carried out inpaper processing industry and the bleaching sequences can be analyzed for efficacy ofbleaching and pre bleaching.
Minimum Description Length Methods in Bayesian Model Selection: Some Applications  [PDF]
Mohan Delampady
Open Journal of Statistics (OJS) , 2013, DOI: 10.4236/ojs.2013.32012

Computations involved in Bayesian approach to practical model selection problems are usually very difficult. Computational simplifications are sometimes possible, but are not generally applicable. There is a large literature available on a methodology based on information theory called Minimum Description Length (MDL). It is described here how many of these techniques are either directly Bayesian in nature, or are very good objective approximations to Bayesian solutions. First, connections between the Bayesian approach and MDL are theoretically explored; thereafter a few illustrations are provided to describe how MDL can give useful computational simplifications.

Innovation for Making Potable Water Available in Saline Groundwater Areas  [PDF]
Lalit Mohan Sharma
Journal of Water Resource and Protection (JWARP) , 2014, DOI: 10.4236/jwarp.2014.614118
Abstract: Groundwater salinity is a widespread problem around the world with adverse consequences on health, soil quality and overall eco-systems. With the rapidly growing demands of groundwater, its exploitation is also accelerating. It is also changing the flow of the groundwater, which in turn causes ingress of sea water or intrusion of other saline groundwater or polluted water from the surrounding areas. The major consequences are scarcity of water even for domestic use and rise in the level and spread of groundwater salinity. An innovative technique of creating a pool of fresh groundwater within a saline aquifer is developed, which can address the issue. Technique is about recharging the saline aquifer with harvested rain water in such a way that recharged rain water does not get mixed with the existing saline groundwater rather it forms pool of fresh water in the saline aquifer. Water from this pool can be extracted without getting it mixed with saline groundwater. This innovation also eliminates the need of cost intensive provision of water storage structures to store rain water for fulfilling the domestic water needs. Thus, the saline aquifer unsuitable or otherwise useless for groundwater development can be used.

Abstract: Using satellite-based 10-m surface wind (SW), wind stress (WS) and sea surface temperature (SST) anomalies, trends and inter-annual variability during 1993 and 2008 over the Southern Ocean (SO) are addressed. The climatological mean (16 years average) indicates that negative wind stress curl diminished (enhanced) between 40°S and 60°S zonal strap region coincide with weak (strong) SW and warm (cold) SST anomaly during January (July). Annual climatology indicates that strong region of SW divides warmer waters northward with positive wind stress curl (WSCL) and colder waters southward with negative WSCL. The time series anomalies are smoothened with a 12-month running mean filter. The filtered area-mean time series anomalies of zonal and meridional component of SW and SST have linear trends of -0.0005 ± 0.0003 m/s/decade, 0.0012 ± 0.0002 m/s/decade and -0.00005°C ± 0.0001°C/decade, respectively. The SW anomalies show an increasing trend of 0.0013 ± 0.0002 m/s/decade, with the meridional (zonal) component exhibiting an increasing (decreasing) trend. The meridional component plays a critical role in heat transfer through atmospheric circulation. The WS and wind stress divergence exhibit increasing trends whereas wind stress curl shows a decreasing trend. The SST fluctuates close to zero with repeated high and low peaks at an interval of 2 - 3 years. We address the interannual variability by performing EOF analysis on SW, WS, WSCL and SST anomalies which have been passed through a 12-month running mean filter.
Assessment of the Implications of GST (Goods and Services Tax) Rollout on Indian MSMEs  [PDF]
Vidit Mohan, Salman Ali
Theoretical Economics Letters (TEL) , 2018, DOI: 10.4236/tel.2018.815219
Abstract: The purpose of this study is to understand the implications of the recent rollout (July 2017) of GST (Goods and Services Tax) in India on the MSME (Micro, Small, and Medium Enterprises) sector. The study comprises a series of qualitative face-to-face interviews which were followed up by a survey with Indian MSME owners. The study provides a multi-dimensional understanding of the gaps between the effect of the anticipated and existing GST regime for the MSMEs and the associated tax compliance. It identifies and assesses the inter-jurisdictional and other issues that are involved in GST implementation. There is scope to probe the means to enable the effective deployment of GST based on the findings of this study. The findings can also be used to develop guidelines for suitable implementation of the GST regime for the MSMEs operating in different sectors.
Non-Toxic Effect of Monascus purpureus Extract on Lactic Acid Bacteria Suggested Their Application in Fermented Foods  [PDF]
Mohan-Kumari Honganoor Puttananjaiah, Mohan Appasaheb Dhale, Vijayalakshmi Govindaswamy
Food and Nutrition Sciences (FNS) , 2011, DOI: 10.4236/fns.2011.28115
Abstract: The effect of Monascus purpureus extract (MPE) on probiotic lactic acid bacteria (LAB) was investigated to ascertain its application in fermented foods. Viable count of LAB was not affected after 24 hours of incubation in Man Rogosa Sharpe (MRS) broth containing MPE. The agar well-diffusion assay did not show any inhibition zone. The biotransformation of isoflavone glycosides by LAB in culture medium supplemented with MPE increased antioxidant activities. These data suggest that, nutritive and biological functionality of fermented foods can be improved by the use of MPE.
Using Image Analysis for Structural and Mechanical Cha-racterization of Nanoclay Reinforced Polypropylene Com-posites  [PDF]
Turup Pandurangan Mohan, Krishnan Kanny
Engineering (ENG) , 2010, DOI: 10.4236/eng.2010.210103
Abstract: This paper focuses on the micromechanical study of the tensile property of Polymer-Clay Nanocomposites (PCN). Polypropylene (PP) filled with nanoclay is chosen as the PCN. Measurements of optical dispersion parameters (as discussed by Basu et al., namely, exfoliation number (ξn), degree of dispersions (χ) and agglomerate %) in PCN system were carried out using Transmission Electron Microscopy (TEM) and Optical Microscopy (OM). The experimentally obtained tensile modulus is compared with theoretically obtained modulus values from the optical dispersion parameters and observed a close matching between these values. Also, the tensile values are compared with other standard theoretical models and observed that the results obtained from optical dispersion parameters are suited well with experimental results.

Turup Pandurangan Mohan, Krishnan Kanny
Materials Sciences and Applications (MSA) , 2011, DOI: 10.4236/msa.2011.27108
Abstract: This work presents the effect of synthetic procedures (extrusion and casting) on the dispersion characteristics of nano layered silicate clay particles in the polypropylene (PP) polymer matrix. Three different molecular weights PP samples are taken and filled with nanoclay of 1 wt% and 3 wt%, and these nanocomposites were synthesized by using an extrusion or casting methods. The X-ray diffraction (XRD) and Transmission Electron Microscopy (TEM) is used to characterize the structure and morphology of nanocomposites. Rheological and mechanical results show that the extruded products are better than that of cast products. The outcome of this work is discussed in this paper.
