Study on the effect of toxicity under highly arsenic prone zone in Nadia district of West Bengal in India

The present study was carried out on the basis of status of arsenic in soil, drinking water and plants, blood, urine and faeces of animals at arsenic prone zone. Within the ambit with the environment, the examination of animals was taken into consideration. They were screened and categorised on the degree of As toxicity. For field works animals were randomly selected from arsenic prone zone. The external manifestation indicated a complex syndrome and characteristic signs such as increased heart rate and respiratory rate, red urine, congested mucous membrane, anorexia, absence of ruminal motility, diarrhoea with blood, polyuria and unusual weight loss. The haematobiochemical changes such as low Hb level, decreased level of TEC, TLC and increased level ALT, AST, BUN and creatinine. Increased level of arsenic in urine, blood and faeces than the value of control animals could be the confirmatory indication of arsenic toxicity

Characterization of Single Cycle CA and its Application in Pattern Classification

AbstractThe special class of irreversible cellular automaton (CA) with multiple attractors is of immense interest to the CA researchers. Characterization of such a CA is the necessity to devise CA based solutions for diverse applications. This work explores the essential properties of CA attractors towards characterization of the 1-dimensional cellular automata with point states (single length cycle attractors). The concept of Reachability Tree is introduced for such characterization. It enables identification of the pseudo-exhaustive bits (PE bits) of a CA defining its point states. A theoretical framework has been developed to devise schemes for synthesizing a single length cycle multiple attractor CA with the specific set of PE bits. It also results in a linear time solution while synthesizing a CA for the given set of attractors and its PE bits. The experimentation establishes that the proposed CA synthesis scheme is most effective in designing the efficient pattern classifiers for wide range of applications

Investigation and Control of Narayanbagar Landslide, District Chamoli, Uttaranchal, India – A Case Study

Incidences of landslide hazards are quite common in the hilly terrain of Himalayas. These landslides not only damage the hill slopes causing enormous loss of slope forming materials but also become responsible for creating frequent disturbances to the moving traffics on hill roads and consequent adverse socio-economic impacts to the communities. As road communication system is the only lifeline for the people residing in the hilly terrain of Himalayas, detailed scientific study of landslide-affected area is , therefore, very much essential to overcome all sorts of geo-environmental and socio-economic problems created by the landslide. Numbers of landslides have already occurred along the stretch of the hill slope adjoining the Almora – Baijnath – Gowaldam – Karanprayag (A-BG- K) State Highway, located in Uttaranchal, in India. The present paper deals with such a problematic Narayanbagar Landslide at 129 km on this Highway. This landslide affected area is situated within the vicinity of Narayanbagar town on the left bank of River Pinder. This is the only road, which connects the two Commissionaires (Garhawal and Kumaun) of Uttaranchal State. Because of the present existing situation of Narayanbagar, which is lying very close to the boundary of Almora and Berinag Nappe, the geology has played a very important major role in creating slope instability in this area. Both geological and geo-technical studies have, therefore, been carried out with a view to understand the cause and mechanism of failure of the hill slope materials and to suggest the best possible suitable remedial measures to stabilize the Narayanbagar landslide affected area

Green Synthesis Nanocomposite Membranes

A nanocomposite membrane includes a macroporous polymer membrane having a plurality of pores. A plurality of metal nanoparticles are synthesized and immobilized within those plurality of pores. The nanoparticles are reduced and capped with a green reducing and capping agent such as green tea extract
