abstract sensitive and precise voltammetric methods for the determination of trace amounts of furaldehydes, mainly as furfural (f) and 5-hydroxymethyl-2-furaldehyde (hmf), in waste waters and other matrices is described. determination of total furaldehyde at < ?g g-1 levels in alkaline buffered aqueous media was individually investigated. by the use of ordinary swv and adsorptive square wave ...
throughout this dissertation r is a commutative ring with identity and m is a unitary r-module. in this dissertation we investigate submodules of multiplication , prufer and dedekind modules. we also stat the equivalent conditions for which is ring , wher l is a submodule of afaithful multiplication prufer module. we introduce the concept of integrally closed modules and show that faithful mu...
Scaling and topology in the 2–d O(3) σ–model on the lattice with the fixed point action Abstract We study scaling properties and topological aspects of the 2–d O(3) non–linear σ–model on the lattice with the parametrized fixed point action recently proposed by P. Hasenfratz and F. Niedermayer. The behavior of the mass gap confirms the good properties of scaling of the fixed point action. Concer...
within communicative, interactive, and learner-centered framework of language teaching and learning, students need to learn four skills of listening, speaking, reading, and writing for their educational success. but of all the language skills, reading enjoys a paramount significance in so many second or foreign language academic contexts. in spite of its importance, language learners still have...

In this study, concentrations of cadmium using 3778 samples encompassing the total size Spain (about 505 km2) were investgated. Two novel spatial methods namely Moran eigenvector spatially varying coefficient (MESVC) and filtered unconditional quantile regression (SF-UQR) employed with aim avoiding problem local collinearity which is prevalent in models. Additionally, coefficients applied to as...
In India, agricultural soil has been deteriorated by various on-going practices involving application of chemical fertilizers, pesticides and effluents. Presently, Amritsar (Punjab), an agricultural land, is undergoing rigorous cultivation of wheat and rice crops which consequently increased the application of chemical pesticides and fertilizers for high yield. These agricultural practices are ...
Comparative Effects of Diaxepam and Midazolam on Paraoxon Toxicity in Rats. KRUTAKKROL, H., AND DOMINO, E. F. (1985). Toxicol. Appl. Pharmacol. 81,545-550. The present study was undertaken to compare the effectiveness of a new water-soluble benzodiazepine, midazolam, to diazepam, both administered im for protection against diethyl-pnitrophenyl phosphate (paraoxon) toxicity. Adult male Sprague-D...
BACKGROUND Heliotropium indicum is used as a traditional remedy for hypertension in Ghana. The aim of the study was to evaluate the anti-glaucoma potential of an aqueous whole plant extract of H. indicum to manage experimentally-induced glaucoma. METHODS The percentage change in intraocular pressure (IOP), after inducing acute glaucoma (15 mLkg(-1) of 5 % dextrose, i.v.), in New Zealand White...
Lichens are widely used to assess the atmospheric pollution by heavy metals and radionuclides. However, few studies are available in publications on using lichens to qualitatively assess the atmospheric pollution levels. The paper presents research results applying epiphytic lichens as bio-monitors of quantitative atmospheric contamination with uranium. The observations were conducted during 2....
