there have been much speculation and debate concerning the effect of electromagnetic fields (emf) on body systems. various reports have implicated excessive exposure to emf to certain forms of leukemia. it has also been reported that emf may cause alteration in the levels of certain macro- and micro-nutrients such as copper, zinc, selenium, calcium and iron. we have undertaken this study to det...

this research aims  to monitor the trace elements content (cr, cu, pb, cd, ag, al, mn, mg, zn and fe) in the tissues of the muscle and liver of silver carp (h. molitrix ) and stone moroko (p. parva) from zarivar wetland in western iran. this research was cross-sectional. the research specimen  was fish caught from zarivar wetland. metal concentration analysis was carried out utilizing an  icp. ...

the levels of serum tota1 protein, albumin, transaminases and phosphatases were estimated in a group of children with severe marasmus or mild malnutrition in order to identify some of the associated deficiencies in these syndromes. the biochemical pattern was similar in the normal and malnourished children.

background: cement production is associated with heavy metal emissions and environmental pollution by cement dust. the degree of contamination of drinking water sources by major and trace elements present in cement dust generated by united cement factory (unicem) is still uncertain. this study estimated the element content of ground and surface water samples (hand-dug wells, boreholes and strea...

this paper aimed to investigate the differences between english and persian religious elements which may be problematic in translating from english into persian. the study aimed also to investigate the way cultural elements in general and religious ones in particular were dealt with in the selected corpora and to check whether the procedures proposed by newmark, were sufficient and adequate for...

nowadays, textile and woven fabric composites are taken into consideration forapplications in high mechanical properties and every in-plane direction. however, developments inmodelling and characterisation of the fabric reinforced composite materials are considered more inthe effects of element types used in the mesh generation of the crack tip. the type of elementselected for the crack tip, a ...

In the separation process, it has been thought that the species present at low levels of acidity are simple metal co-ordination compounds. However, our own structural studies on a number of terdentate ligands have shown a large variety of structural types which depend on the nature of the ligand and on the lanthanide concerned. In order to gain insights into the coordinative mechanism of extrac...

For every central element z of a lattice effect algebra E, the interval [0, z] with the ⊕ operation inherited from E and the new unity z is a lattice effect algebra in its own right. We show connections between blocks, sharp elements and central elements of [0, z] and those of E. We prove that except for central elements, the intervals [0, z] are closed with respect to the ⊕-operation also for ...

The symmetric coupling of mixed nite element and boundary element methods is analysed for a model interface problem with the Laplacian. The coupling involves a further continuous ansatz function on the interface to link the discontinuous displacement eld to the necessarily continuous boundary ansatz function. Quasi-optimal a priori error estimates and sharp a posteriori error estimates are esta...
