in this research, the groundwater quality of hoz–e–soltan lake and its catchment was studied for drinking, domestic and irrigation uses according to different parameters. this lake with 195 km2 catchment area is located 85 km of southwest of tehran–qom highway. in order to investigate groundwater quality characteristics in the study area, 34 data from water of well belong to 2008 selected to pr...

The category of graded, bicommutative Hopf algebras over the prime eld with p elements is an abelian category which is equivalent, by work of Schoeller, to a category of graded modules, known as Dieudonn e modules. Graded ring objects in Hopf algebras are called Hopf rings, and they arise in the study of unstable cohomology operations for extraordinary cohomology theories. The central point of ...

The problem of strongly correlated electrons in one dimension attracted the attention of condensed matter physicists since early 50’s. After the seminal paper of Tomonaga [8] who suggested the first soluble model in 1950, there were essential achievements reflected in papers by Luttinger [6] (1963) and Mattis and Lieb [7] (1963). Considerable contribution to understanding of the generic propert...

<abstract> <p>Municipal solid waste landfills leachate can cause serious environmental issues for groundwater quality. Therefore, the application of tracing methods to identify contamination by municipal is significant. Hydrogeochemical evaluations trace are usually carried out. The study was out at a landfill in central Italy (Umbria). Samples and have been analyzed evaluate impact...

If (Q,n) (R,m) is a surjective local homomorphism with kernel I, such that I ⊆ n and the conormal module I/I has a free summand of rank n, then the degree 2 central subspace of the homotopy Lie algebra of R has dimension greater than or equal to n. This is a corollary of the Main Theorem of this note. The techniques involved provide new proofs of some well known results concerning the conormal ...

A nswer: Dyspnea (breathlessness), an unpleasant awareness of breathing, is a subjective experience. This symptom is all too common, with reports of more than 70% of patients with advanced cancer experiencing this symptom (Ripamonti, 1999). Unfortunately, the mechanisms that lead to dyspnea are not well understood. Patients’ self-report of dyspnea is the best indicator of its presence and level...

introduction: in recent years, due to the reduction in surface water, utilization of groundwater has been increased to meet the growing demand of irrigation water. the quality of these water resources is continually changing, due to the geological formations, the amount of utilization, and climatic parameters. in many developing countries, the irrigation water is obtained from poor quality grou...

A spectral-based imaging system was constructed consisting of a two-sequential-absorption-filter-CFA digital camera and a seven-color inkjet printer and used to image and print a post-impressionist style painting such that matches were generated for CIE Illuminants D65 and A. Camera calibration was learning based using the Matrix R method. Rendered images for both illuminants were inputted to a...
