Soil sampling was carried out by quartering method in different impact zones of deforestation, such as adjacent, fringe and deep forest area. Soil samples were collected from top 15 cm soil layer. Different physico-chemical parameters were analysed and compared to assess the extent to which impacts of deforestation had occurred. Results indicated a clear distinction in soil quality from adjacent, fringe and deep forest area. Bulk density, pH and conductivity of soil samples were higher in adjacent area as compared with fringe and deep forest area. Whereas micronutrients concentration, such as iron and nickel was lower in adjacent area as compared with fringe and deep forest area. Due to significant anthropogenic activities in adjacent area, soil erosion had occurred and thus leads to more bulk density, pH and conductivity whereas less organic carbon, iron and nickel concentration as compared with fringe and deep forest area. Deforestation due to anthropogenic activities had adverse impacts on soil quality and thus reducing the forest cover from the study area. © 2012 - Kalpana Corporation. Source

The experiential data for density (r) and speed of sound (u) have been obtained for aqueous solutions of acetonitrile, dimethyl formamide, dimethyl sulphoxide, dioxane, ethylene diamine, ethylene glycol, pyridine and tetrahydro furan at 298.15 and 308.15 K. The data have been processed to compute the derived parameters such as isentropic compressibility of solution (β S), apparent molar volume of solute (Φ V) and apparent molar isentropic compressibility of solute (φ KS). The results obtained have been interpreted in terms of solute-solvent and solute-solute interactions and hydrogen bonding between dissolved solutes and solvent molecules. Source

Farm tank (bodi) constitutes a small water reservoir constructed by using available natural materials to store rainwater for irrigation purposes during post monsoon season. It receives water from rainfall and runoff from the surrounding catchment area during monsoon period and this serves for irrigation purposes of paddy fields. An investigation was carried out to ascertain the suitability of farm tank water quality for paddy fields from the study area by estimating various physico-chemical parameters of one farm tank for the post monsoon season in 2005 and 2006. Results show that sodium, total alkalinity, chlorides were found as the constituents affecting irrigation water quality. It can be concluded that farm tank water was best suited to use for irrigation purposes during post monsoon season for paddy fields. This is the first study for the farm tank water quality assessment for irrigation purposes for paddy fields from the study area. © 2012 - Kalpana Corporation. Source

Density and viscosity measurements are reported for aqueous solutions of the drugs like Metformin hydrochloride (MH), Ranitidine hydrochloride (RH) and Tramadol hydrochloride (TH) at different temperatures T = (288.15, 298.15, and 308.15) K within the concentration range (0 to 0.15) mol·kg -1. The density and viscosity data are used to obtain apparent molar volume of solute (φ V) and relative viscosity (η r) of aqueous solutions at different temperatures. The limiting apparent molar volume of solute (φV0), limiting apparent molar expansivity (φE0), thermal expansion coefficient (α*), hydration number (n h), Jones-Dole equation viscosity A and B coefficients, experimental slope (S V) at different temperatures, and temperature coefficient of B i.e. (dB/dT) at T = 298.15 K were also obtained. The results obtained have been interpreted in terms of solute-solvent and solute-solute interactions and structure making/breaking ability of solute in the aqueous solution. © 2011 Elsevier Ltd.

In this work, we report the determination of energy volume coefficient (Pint =(U/V)T also called as an internal pressure (Pint) in the dilute concentration region for the basic carbohydrates i.e., glucose, fructose, sucrose, galactose and lactose in aqueous solutions at 288.15 K in the concentration range 0-0.05 mol kg-1. To obtain this one requires precise isothermal compressibility and expansivity data. We used earlier reported data of density (&raugh) and speed of sound (u) obtained at 278.15, 288.15 and 298.15 K; assuming specific heat (φP) is nearly the same in the studied concentration region. The internal pressure for solutions is found to increase with concentration of solute linearly and the increase depends upon the number of polar hydroxyl groups and conformational characteristics of the carbohydrate molecules. It is well known that apparent molar volumes of (fV) of these compounds do not vary with concentration in dilute solution region (almost ideal solutions), while the conformational specificity is reflected only in limiting partial molar volumes because of solutesolvent interactions. We applied Gibson-Tait equation of state to internal pressure data and obtained limiting excess molar volumes (V ) 0E 2 and found that values of excess molar volume of these compounds are highly negative (-31 × 10-6 to -62 × 10 -6 m3 mol-1) at 288.15 K. These are large negative when compared with the molar volume data of solid carbohydrates. The differences are attributed to void volume and cage volume contribution to the total volume of solute molecule. It is invoked that when carbohydrates are dissolved in water, almost all free and void volumes are being used up due to dipole (-OH) and water molecular interactions through hydrogen bonding and retaining water structural characteristics intact in solution phase.
