Comparative phytochemical and antibacterial activities of bark of Wrightia tinctoria and Wrightia arborea were investigated. The bark extracts showed the presence of alkaloids, phenolics, saponins and tannins in both the species. The antibacterial activities of bark of W. tinctoria and W. arborea in successive different solvent were tested against gram +ve and gram -ve organisms. The chloroform extracts of W. arborea showed the broader spectrum of antibacterial activity when compared with W. tinctoria. However, Wrightia tinctoria is a widely used medicinal plant.

Polycrystalline ferrites with general formula Ni1+xTi xFe2-2xO4, where 0.0≤x≤0.7 were prepared through double sintering ceramic technique using A.R. grade oxides of respective ions. The phase purity of all the samples was checked by X-ray diffraction (XRD) technique. The X-ray diffraction pattern shows all reflections belonging to cubic spinel structure. No extra peak other than cubic spinel was observed in the X-ray diffraction pattern. Using XRD data, the lattice constant was calculated for all the compositions. The lattice constant decreases linearly with Ti4+ substitutions and obeys Vegard's law. The magnetic properties (saturation magnetization, magneton number, coercivity) were investigated using pulse field hysteresis loop technique at room temperature. The values of coercivity decreases with Ti4+ content increases. The saturation magnetization and magneton number both significantly decreases with increase in Ti4+ substitution. Mössbauer spectra of all the samples exhibit sextet. The Mössbauer parameters obtained from Mössbauer spectrum revealed the influence of titanium substitution. © 2012 Elsevier B.V.

The modern civilization, industrialization, urbanization and increase in population have led fast degradation of water resources. About 80% of all the diseases of human beings are caused by water since it is directly related with human health. Therefore, it is necessary to create awareness among the present and future generation about water quality. In view of this, the Sangamner area of Ahmednagar district, Maharashtra, India is selected to study the chemistry of groundwater quality and its suitability to drinking purposes, where the groundwater is main source for irrigation and drinking. The groundwater samples were collected from fifty seven locations covering the entire study area during pre-monsoon and post-monsoon season. The samples were analyzed for different physico-chemical parameters like pH, EC, TDS, Na +, K +, Ca 2+, Mg 2+ Cl -, HCO - 3,SO 4 2-,NO 3 - and Fe using standard methods. It was found that the parameters like TDS, Na, Ca, Mg, total hardness and nitrate were exceeded the permissible limit in the majority of the samples particularly from irrigated area. Few samples exceeded the maximum permissible limit of chloride. On the basis of TDS, the ground water is classified as fresh, slightly saline to moderately saline and very saline in character. The comparisons of the groundwater quality in relation to drinking water with Indian standard - drinking water specification - 1991, proves that water quality in most of the villages in the irrigated area is unsuitable for domestic purposes and proper treatment is needed before using it for drinking purpose. © 2011 RASĀYAN.

In the present study attempts have been made to evaluate the soil fertility status from Sangamner area, Ahmednagar district, Maharashtra. 62 surface soil samples were analyzed for various soil fertility parameters like pH, EC, organic matter, available NPK and boron by standard procedures. pH ranged from 8 to 9.7 reflecting alkaline nature of soils. Higher EC in the downstream part reflecting low flushing rate and sluggish ground water movement in the area. Organic carbon ranges from 0.165 to 1.575% in the soils. 29.03% and 48.38% of soils showed low and medium status of organic carbon respectively. Low status of organic carbon in some soils of the area is indicating that adequate nitrogen fertilization through organic manure, FYN etc are required. Soils showed low contents of available nitrogen and phosphorus, while available potassium was high. Available boron ranged from 0.02 to 14.42ppm. Boron is found to be higher in salt affected soils which are located in the downstream part of Pravara River. It was found that 56.45 % boron concentrations were safe, 9.67% marginal and 33.81% reflect unsafe class of soil samples in the area. Improper agriculture practices, intensive farming, monoculture type of cropping pattern and over irrigation are responsible for degradation of soil fertility from the area. To overcome the adverse effect, complimentary use of biofertilizers, organic manures in suitable combination of chemical fertilizers were suggested. Awareness camps, rallies and training programmes can be arranged for farmers regarding the benefits of balanced use of chemical fertilizers and use of organic agriculture in crop production in improving soil fertility and nutrition status. © 2012 RASÄYAN.

Health diseases occurring due to high fluorine concentration in drinking water are a widespread problem in the world. To get the information of the fluoride concentration in ground water was determined in 10 samples of Jorve village Sangamner, Maharashtra, India. The fluoride concentration in the underground water of these village varied from 0.01-2.13 mg/L. various other water quality parameters, viz., Temperature, pH, electrical conductance, total dissolved solids, fluoride, sodium, potassium, chloride, calcium hardness, magnesium hardness, sulphate, nitrate, DO, etc. were also measured. TDS and Hardness of the samples do not comply with Indian as well as WHO standard for most of the water quality parameters measured. Overall water quality was found unsatisfactory for drinking purpose. Fluoride content was higher than the permissible limit in 50% samples. © 2013 RASĀYAN. All rights reserved.
