batiaghata upazila, khulna district in south-west coastal region of bangladesh is the mostly saline affected area, where agriculture activities are mainly dependent on rainfall. 23 water samples from surface water and shallow tube well (stw) were collected in the monsoon season and analyzed for physico-chemical properties to classify them according to salinity hazard. electrical conductivity (e...

a study was made on the interaction between histon h1 and sodium n-dodecyl sulphate (sds) in the presence of sodium arsenate inside a phosphate buffer of ph 6.4, using spectroscopy and equilibrium dialysis at 27 °c. the binding data has been used to obtain the gibbs free energy in terms of a theoretical model based on the wyman binding potential. the binding data hs been analysed in terms of hi...

Conductive polymers (CPs) are organic materials that hold great promise for biomedicine. Potential applications include in vitro or implantable electrodes for excitable cell recording and stimulation and conductive scaffolds for cell support and tissue engineering. In this study, we demonstrate the utility of electroactive CP polypyrrole (PPy) containing the anionic dopant dodecylbenzenesulfona...

Title of Thesis: CHRONOAMPEROMETRIC STUDY OF CONFORMATIONAL RELAXATION IN PPY(DBS) Bryan Jason West, Master of Science, 2008 Thesis directed by: Professor Elisabeth Smela Department of Mechanical Engineering Professor Benjamin Shapiro Department of Aerospace Engineering In conjugated polymer devices that switch from one oxidation level to another, such as artificial muscles, it is important to ...

Poly (urea-formaldehyde) (PUF) shelled dicyclopentadiene (DCPD) microcapsules were prepared by in-situ polymerization technology for self-healing concrete applications. It’s found, during the process, sodium dodecyl benzene sulfonate (SDBS) behaves better in emulsification of DCPD than other surfactant of sodium lauryl sulfate (SLS) and styrene maleic anhydride copolymer (SMA), and the addition...

the methanolic leaf extract of thuja occidentalis was evaluated for possible sedative activities in mice. sedative activity was evaluated by using hole cross, open field, thiopental sodium-induced sleeping time and elevated-plus maze (epm) tests at 200mg/kg and 400 mg/kg.  the extract decreased the locomotor activity of mice in hole cross, open field and epm test and showed the remarkable resul...

to determine the complications of gold sodium thiomalate therapy in rheumatoid arthritis (ra), 32 patients with active ra (27 female, 5 male) treated for a mean period of 28 ? 14 weeks were studied. from these patients, 62.5 (46-79) percent showed at least one drug reaction. pruritus was the most common complication occurred in 59 (42-76) percents, and was accompanied by skin rush in 37 (15-57)...
