Effects of concentration and solvent composition on the electrical conductivity of sodium bromide in pure water and ethanol-water mixed solvent media
Get PDFPrecise measurements on the conductivity of Sodium Bromide in pure water and ethanol-water mixed solvent media containing 0.10, 0.20, 0.30, 0.40, 0.50 and 0.60 volume fractions of ethanol at room temperature are reported. The concentrations were varied from ~ 0.010 to ~ 0.10 mol.L-1. The results showed a sharp increase in the conductivity with increasing electrolyte concentration. The conductivity of electrolyte decreases with increase in the amount of ethanol
Time dependent temperature distribution model in layered human dermal part
Get PDFThe paper developed application of finite element method with linear function in the study of temperature distribution in the layers of dermal part-stratum corneum, stratum germinativum, papillary region, reticular region and subcutaneous tissues as elements. The method is applied to obtain the numerical solution of governing differential equation for one dimensional unsteady state bio-heat transfer using suitable values of parameters that effect the heat transfer in human body. The numerical results obtained are exhibited graphically for various atmospheric temperatures for comparative study of temperature distribution profiles. The loss of heat from the outer surface of the body to the environment is taken due to convection, radiation and sweat evaporation
Endophytic Fungi Associated with Twigs of Buddleja asiatica Lour
Get PDFEndophytic fungi were studied in twigs of Buddleja asiatica at two sites within Kathmandu city, Nepal. Sterile mycelia and five fertile taxa (Alternaria, Fusarium, Epicoccum, Phoma, and Cladosporium) were isolated. Alternaria, Fusarium, and sterile mycelia were isolated from both sites, whereas Epicoccum, Phoma, and Cladosporium were site-specific. Colonization frequency, isolation frequency, and diversity of fungi were higher at Site II compared to Site I

A Review on Macroinvertebrates’ Physiological Response to Regulated Stream Flow
Get PDFShort rainfall, elevated rates of evaporation, exhaustion of underground water levels, and highly inconsistent stream flow regimes have encouraged the construction of big dams and other water-regulating infrastructure development, resulting in the degradation of river ecosystems. These major changes transform and reduce the biological composition of rivers, isolating populations of aquatic life and their habitats within a river. Invertebrates account for roughly 95% of all animals, so it is important to understand their physiological response to various stressors related to changes in flow regime. This review summarizes the ecological impact of dams in river ecosystems, specifically on macroinvertebrates and their physiology, and highlights potential stressors responsible for environmental disruption

Some matrix transformations and almost convergence
Get PDFThe sequence space bv(u,p) has been defined and the classes (bv(u,p):l?), (bv(u,p):c),and (bv(u,p):c0) of infinite matrices have been characterized by Ba?ar, Altay and Mursaleen ( see, [2] ). The main purposes of the present paper is to characterize the classes (bv(u,p):ƒ?),(bv(u, p):ƒ), and (bv(u,p):ƒ0), where ƒ?, ƒ, and ƒ0 denotes the spaces of almost bounded sequences, almost convergent sequences and almost convergent null sequences, respectively, with real or complex terms.

Isolation and Characterization of Arsenic Resistant Pseudomonas Stutzeri ASP3 for its Potential in Arsenic Resistance and Removal
No full textInorganic arsenic both arsenite As (III) and arsenate As (V) constitute the highest toxicological risk associated with arsenic in drinking water. Novel methods are in demand for its removal from water, especially in rural areas. For this purpose, the potential of different microbes in arsenic resistance and removal from water has gained interests worldwide. This study investigates the arsenic resistance and removal capacity of a bacterial strain isolated from arsenic enriched water of Rautahat district in Nepal. The concentration of arsenic was by hydride generation atomic absorption spectrophotometer. The isolated bacterium showed high resistance to sodium arsenate up to 4,680.15 mg/l and sodium arsenite up to 649.55 mg/l. The bacterium also conferred multiple heavy metal resistance to zinc chloride (136.28 mg/l), copper sulphate (249.68 mg/l), mercuric chloride (5.43 mg/l) and silver nitrate (3.39 mg/l). The growth rate calculated in the presence of 129.01 mg/l of sodium arsenite was 0.35 h-1 with doubling time of 1.96 h. The strain showed growth in the range of 25–45 °C (optimum 30-35 °C), pH 6 – 9 (optimum 7.5-8.5) and tolerated up to 10% of NaCl. The PCR-based 16S rDNA sequence analysis revealed that the isolated As resistant bacterium is a close relative to P. stutzeri (99%) with 30 hits. The bacterium removed 82.97 % of As (V) and 49.4% of As (III) from culture medium amended with 200 mg/l sodium arsenate and 74.92 mg/l of sodium arsenite respectively
On the 3rd order linear differential equation
