The paper deals with the results of ethnobotanical survey work carried out during 2005-2006. The information was collected from 13 villages, mostly of remote places near the border area of Arunachal Pradesh. Totally, 20 plant species were collected and recorded for their use in various ailments. The species are short listed giving their plant name, family, vernacular name, and uses.


The Sonitpur district is one of the most important tea growing district of Assam. There are big tea estates (under multinational companies) as well as a large number of small tea gardens growing which is like a green revolution. In these gardens heavy amount of artificial agrochemicals are used which contaminates soil as well as drinking water sources. Ground water is an essential and vital component of our life support system. The groundwater resources are being utilized for drinking, irrigation and industrial purposes. There is growing concern on deterioration of groundwater quality due to geogenic and anthropogenic activities. Groundwater, being a fragile must be carefully managed to maintain its purity within standard limits. In tea gardens belt the agro-chemicals affect the quality of groundwater so this investigation has been carried out to assessment the quality of water in this area. Now the Fluoride and Arsenic are major problems in ground water in India and Bangladesh, the heavy metals also effect the chronic health hazards of the people in this area so it is very important to investigation of ground drinking water sources. The ground water of this area is of high iron, manganese, fluoride and arsenic concentration is observed. Finally, stress zones in the study area were delineated using Arc GIS spatial analysis. © 2016, Sphinx Knowledge House. All rights reserved.

A transformation method is applied to the second order ordinary differential equation satisfied by orthogonal polynomials to construct a family of exactly solvable quantum systems in any arbitrary dimensional space. Using the properties of orthogonal polynomials, the method transforms polynomial differential equation to D-dimensional radial Schrodinger equation which facilitates construction of exactly solvable quantum systems. The method is also applied using associated Laguerre and hypergeometric polynomials. The quantum systems generated from other polynomials are also briefly highlighted.

Contamination of drinking water by arsenic and other heavy metals and their related toxicology is a serious concern now-a-days. Millions of individual world-wide are suffering from the arsenic and other heavy metal related diseases due to the consumption of contaminated groundwater. 60 water samples from different sources of 6 small tea gardens of Sonitpur district were collected to study the potability of water for drinking purposes. The water samples collected from sources like tube wells, ring wells and ponds were analyzed for arsenic, heavy metals like iron, manganese and mercury with sodium, potassium, calcium, magnesium, pH, total hardness, chloride, fluoride and sulphate. Some drain water samples of the tea garden areas were also collected to analyze the above mentioned water parameters to see the contamination level. Experiments revealed that 78% samples of total collection had arsenic content above the permissible limit (0.01 ppm) of WHO guideline value for drinking water. The highest arsenic was observed 0.09 ppm at one sample of Gobindra Dahal tea garden of Gohpur sub division of Sonitpur district. 94% samples had contamination due to manganese 39% samples had iron and 44% samples had Hg. The water quality data was subjected to some statistical treatments like NDA, cluster analysis and pearson correlation to observe the distribution pattern of the different water quality parameters. A strong pearson correlation coefficient was observed between parameters-arsenic and manganese (0.865) and arsenic and mercury (0.837) at 0.01 level, indicated the same sources of drinking water contamination.

Objective: To examine the effect of the root extract on the growth factor during early pregnancy from day 2 to day 6 of gestation. Methods: A purified form of root extract of Polygonum hydropiper was obtained by Thin Layer Chromatography (TLC). Localization of transforming growth factor (TGF)-βI was studied by immunohistochemistry and the expression of the mRNA of TGF-βI was studied by Reverse transcriptase Polymerase Chain Reaction (RT-PCR) in uterine tissue from day 2 to day 6 of gestation. Results: The TLC fraction treated in a dose of 5 mg/kg body weight per day showed decreased the number of implantation sites. The expression of TGF-βI from day 2 to day 6 of gestation was altered by the TLC fraction and suppression of the mRNA transcript of the TGF-βI on day 6 of gestation during implantation. Conclusion: The root extract of Polygonum hydropiper in a dose of 5 mg/kg body weight per day decreased the expression of TGF-βI in the implantation sites of rat uterus. © 2011 The Editorial Board of Journal of Reproduction and Contraception.

Exact analytic solutions of the Schrödinger equation are obtained for classes of newly constructed potentials which are generated from the trigonometric Rosen-Morse potential as the input reference potential via extended transformation method. A set of quantized energy spectra of the bound states and the corresponding wave functions of the generated potentials are obtained. We also focus on to the Romanovski Polynomials which is a family of the real orthogonal polynomials and is required to present exact real analytic solutions of the generated potentials. © 2010 IACS.

Agrochemicals is very essential for healthy production of any crops, Assam the state of India is one of the major tea production state, 60% of tea is produced in India only Assam. In the tea gardens a huge amounts of agrochemicals is used for high yield but the effect of agrochemicals in soil and water is ignore, the agrochemicals from soil leashes to drinking water sources and contaminant the water sources. A total of 30 soil and water samples(different sources) were collected from 10 small tea gardens of Sonitpur district,Assam for analysis, It is observed that the soil health is not in accordance with the fertility rating chart given by ICAR (2005). After analysis in the water samples As, Fe, Mn, Cd have found above WHO limit. This is because of excessive use of agrochemicals. The worst victims by agrochemicals were the tea garden community who are directly related to tea gardens. The researchers feel that environmental aspects of soil quality of this area need serious attention in near future for better agricultural practices and human health. © Research India Publications.

According to WHO, about 80% of all the diseases of human beings are caused by water. Since these diseases are directly related with human health, it is necessary to bring awareness among the present and future generation about the consequences of water pollution. Therefore, in this study 34 samples from different sources such as dug wells, bore wells, hand pumps and ponds, where no information is available, were collected during 2008.The samples were analyzed for different physico-chemical parameters like chloride, sulphate, nitrate, sodium, potassium, calcium, magnesium, iron, copper, cadmium, chromium, lead and zinc using standard methods. The result indicated that chloride and nitrate concentrations in all the sources were within the permissible limit, but ponds contained high amount. The concentrations of sulphate, sodium and zinc in dug wells and bore wells were very high and the concentrations of calcium and chromium were within the permissible limit. In case of lead and calcium their concentrations in ponds were higher than the other sources but chromium was not detected in ponds and hand pumps. The iron and copper concentrations in all the sources exceeded the WHO value, particularly dug wells and bore wells contained high concentrations. Magnesium content was greater than potassium and less than sodium in dug wells and bore wells, but in ponds its concentration was greater than the other sources. In our investigation the results indicate that TDS, EC, pH, BOD, DO, COD, TSS were found very high. In 76% samples turbidity exceeded WHO guideline value 5NTU. It was found that 97% and 76% of the sources were positive for TC and FC. Overall analysis revealed that 11 samples were fit for drinking purpose with respect to the parameters studied.
