Density, viscosity and ultrasonic velocity studies has been carried out in aqueous solution of poly vinyl alcohol at 1 MHz frequency. Measurements were carried out in temperature 30ºC at concentration 1.0%, 0.8%, 0.6%, 0.5%, 0.4% and 0.3%. From these acoustical parameter acoustic impedance have been calculated by using measured values of ultrasonic speed, density and […]

Study of Drying characteristics of Terminalia bellirica and feasibility analysis of locally built solar dryer
The present article is focused on the evaluation of economic and efficiency feasibility of solar dryer for drying Terminalia bellirica. In addition total useful energy required for drying Terminalia Bellirica (bahera) is also evaluated. In this perspective a lab scale, low cost natural convective solar dryer was locally fabricated. Different parameters viz. amount of moisture […]
Effect of salt stress on different germination and growth of Oryza sativa
Oryza sativa is a major crop plant cultivated on a large scale to supply the demand of food requirement of ever increasing population. In the present study seeds of rice plant were germinated onto soil treated with different concentration of three salts (NaCl, PbNO3, CuSO4) and their effect was germination rate and other growth parameters […]
In Vitro Assessment of Salinity Tolerance in Chickpea (Cicer Arietinum L.)
The calli raised from cell culture of chickpea genotypes viz., CSG 8962 Karnal Chana-1 (Salt tolerant), CSG 8890 (salt sensitive) and Bio 104 on MS medium supplemented with BAP (0.5 mg/1)+ NAA (0.5 mg/l) and 40 g/l sucrose were subjected to different salt and salt mixtures. With increasing concentration of salt and salt mixtures, there […]
Prufer Sequence and Graceful Graphs
Pr fer in 1918 showed one-one mapping between a labeled tree of n vertices and (n-2) tuples of labels of vertices. An unproven conjecture “The Graceful Tree Conjecture” is the most elusive conjecture in the realm of the graph labeling technique. In this paper, we have tried to correlate Prufer encoding scheme and graceful theme […]
Emerging Needs Of Sustainable Technology- Solar Photovoltaic Development In India
Solar Power generation in India ranks within top five countries of world in Green energy revolution. Photovoltaic (PV) cells, or solar cells, are active photoelectric system converting sunlight to electricity. Small panels are constructed with semiconducting material based on photoelectric effect. The material, usually used comprises silicon with potentially other polycrystalline thin films, generating direct […]
Antibiotic potential in Indian Herb Hemidesmus indicus
India has one of the world’s richest flora with about 120 families of plants comprising 1,30,000 species and about 119 secondary plant metabolites are used globally as drugs. Hemidesmusindicus, an Indian herb which has potential of medical importance, which is supported by the present study . In this study bioactive compound2-Hydroxy-4-methoxybenzaldehyde (2H4MB) was isolated which […]
A Distributed Generation Model Based On Current Scenario Of Uttar Pradesh: A Socio-Economic Approach
This study demonstrates the hybrids distributed generation model which can be a cost effective solution for providing energy services in rural Uttar Pradesh. Distributed Generation can help to reduce both technical and non-technical losses by decreasing the grid issues, needed to deliver adequate and quality electricity. The high costs of delivering power to remote areas […]
