Infra Red Spectra of Different Species of Cultivated Oyster Mushrooms Possible Tool for Identifying Bioactive Compounds and Establishing Taxonomic Linkage

Mushrooms are macrofungi that serve as a vegetarian source of protein along with various bio-active molecules of primary health importance. The activity of the bio-active molecules range from antioxidant, immunomodulation, hepatoprotection. Cultivated oyster mushrooms are also rich in these components which may be estimated quantitatively by skill intensive ‘destructive’ chemical techniques. Infra Red spectroscopy provides a non-destructive user friendly technique to quickly assess the presence of bio-active compounds in mushroom species to be used as a quality control measure as this non-destructive tool can be used to segregate mushroom harvest according to availability of bioactive compounds. IR spectra based strain classification and taxa delimitation of mushroom samples are also attempted vis a vis DNA sequence based phylogeny analysis of the same, but no correlation is observed between the two types of phylogeny analysis

Patterns of Information Seeking Behaviour of Law Students in Digital Environment: A Study

Nowadays the enormous growth of modern information communication technologies and its massive use have influenced information users all over the world. Such a digital environment has drastically changed the information seeking patterns of information users of every community. These also tend law students to use various legal information sources and services in digital environments while seeking information. But there have been few empirical user studies on the aspect of digital information seeking behaviours of law students in either law or library and information science literatures. This paper aims to draw out patterns of information seeking behavior of students of law in digital environments at the University of Dhaka. A stratified random sample survey was conducted for this study. The results show that students prefer the electronic format of information rather than printed format. Major e-resources used by them and the influential factors of use were also identified in this study. This study also identified some crucial problems for seeking information and provides suggestions for the development of electronic legal information systems

The use of Medicinal Plants for the treatment of Gonorrhoea and Syphilis in South West Bengal of India

Gonorrhoea and Syphilis as Sexually Transmitted Infections occur throughout the world. In India the prevalence of these diseases are in alarming situation due to the rapid spread of the diseases, high cost of treatment and the increased risk of transmission. Current therapies available for symptomatic treatment are quite expensive beyond the reach of common people and associated with the emergence of drug resistance. Many patients seeking help from the alternative systems of medicines for treatment. In our country several crude plants are used as medicine since Vedic period. Herbal medicines provide rational means for the treatment of many Sexually Transmitted Infections. The herbal medicines have many advantages: have no side effects, better patient tolerance and relatively less expensive. Locally available herbal practitioners or healers have practiced since past in this direction. Furthermore the acceptability of herbal medicines are greater to control these infections due to the social stigma associated with them and in case of women it is much more acceptable to discuss their problem with the traditional healers or herbal medical practitioners. In the present study thirty seven medicinal plants have been recorded for the treatment of Gonorrhoea and Syphilis and documented from South West Bengal of India

Dominant urban form and its relation to nighttime land surface temperature in the rapidly urbanizing National Capital Region of India

Urban form is generally accepted to be the most significant aspect controlling LST. This study analyzes the spatio-temporal urban growth pattern in India's rapidly urbanizing National Capital Region (NCR) to discern its dominant urban form based on urban sprawl metrics (USM - a neighborhood based built-up density approach) and traces its spatio-temporal growth patterns. It then gauges the relations between the landscape composition and various development modes of this dominant urban form with the ascertained nighttime LST distribution. The results of the USM based analysis show that the NCR's dominant urban form is constituted by the urban core, which has expanded markedly during the study period of 2000-2018. Within the urban core, nighttime LST increased, particularly during the fall months. Linear regression models (both non-spatial and spatial) reveal a positive relation between the nighttime LST and the built-up area and infilling growth mode. Contrarily, nighttime LST is negatively correlated with the edge-expansion and the respective areas under urbanized green and non-green open spaces. New planning approaches are thus required to restrict infilling based densification and promote well-planned edge-expansion with the designation of new green spaces as well as the greening existing non-green open spaces, particularly in areas underprovided with greenery
