Understanding the evolution, and managing the reengineering of a large Web site is as hard as evolving a large software system of comparable size. Evolution and maintenance of traditional legacy systems have been extensively studied by reengineering researchers. However, Web site evolution and migration is a new domain with many open questions. We propose the development of a Web site architect...
fluorescence chemical sensors for the highly sensitive and selective determination of pb2+ , hg2+, co2+ and fe3+ ions in aqueous solutions are described. the ion sensing system was prepared by incorporating lipophilic ligand (l) as a neutral ion-selective fluoroionophore in the plasticized pvc membrane containing sodium tetraphenylborate or potasium tetrakis (p-chlorophenyl) borate as a liphoph...
One of the imperative features of the oral cavity is the presence of different areas, which are characterized by unique sets of tissue organization. These regions are divided into lining mucosa (buccal mucosa, labial mucosa, alveolar mucosa, mucosa lining the ventral surface of the tongue, floor of the mouth, and soft palate) and masticatory mucosa (hard palate, attached gingiva, and dorsal sur...
Not all sites in protein sequences evolve at the same rate during the course of evolution. The working hypothesis assumes that evolutionary conserved sites in a protein sequence point to functionally important regions. Thus, identifying conserved regions in a protein impacts such areas as functional annotation studies, drug design, quaternary structure prediction, and protein biochemistry [1]. ...
Making an informed decision with regards to a suitable business location or site selection for organizations is becoming challenging for business decision makers globally; and even more challenging in business environment that are saddled with uncertainties. The continues raise of multiple criteria variation of site preferences has also necessitated the application of advanced decision making t...
the history of plant’s used for mankind is as old as the start of humankind. initially, people used plants for their nutritional proposes but after the discovery of medicinal properties, this natural ?ora became a useful source of disease cure and health improvement across various human communities. berberis vulgaris is one of the medicinal plants used in iranian traditional medicine. berberis ...
this research was conducted in two protect and destroy region in the middle zagros, in illam province. in order to identification of ecological species group and evaluate density of regeneration, effect of many factors such as protection, vegetation, physiographic factors, physical and chemical properties of soil in study locations were studied. to achieve these purpose number of 54 plots using...
Passive sampling devices (PS) are widely used for pollutant monitoring in water, but estimation of measurement uncertainties by PS has seldom been undertaken. The aim of this work was to identify key parameters governing PS measurements of metals and their dispersion. We report the results of an in situ intercomparison exercise on diffusive gradient in thin films (DGT) in surface waters. Interl...
the present study was an attempt to conduct a contrastive analysis between general english (ge) and english for specific purposes (esp) texts in terms of cohesion and cohesive devices. to this end, thirty texts from different esp and ge textbooks were randomly selected. then they were analyzed manually to find the frequency of cohesive devices. cohesive devices include reference, substitution, ...
