In a de-regulated open access environment, reactive power is one of the ancillary services which must be provided by an Independent System Operator (ISO). In this paper, a new algorithm is proposed in which reactive power resources are initially so tuned that optimum security in terms of voltage profile and voltage stability are achieved while at the same time, the system losses are minimized. ...

background: flat urothelial lesions comprise a spectrum of morphologic changes ranging from reactive atypia to carcinoma in situ (cis). urothelial dysplasia and cis are associated with the recurrence and progression of urothelial carcinoma. distinguishing cis and dysplasia from reactive atypia based on histolopathogical features alone is often difficult. using different immunohistochemical mark...

bokbunja seed wastes from a wine manufacturing industry were used to prepare carbon for the purpose of using it as an adsorbent for the removal of reactive blue 4 from aqueous solutions. a part of prepared carbon was treated with n-hexane to remove the seed oil present in large amounts in bokbunja seeds. it was found that the hexane treated carbon was more efficient in removing the dye from aqu...

background; conventional chemical coagulation is considered as the old method to color and cod removal in textile effluent. electrocoagulation (ec) process is a robust method to achieve maximum removal. methods; this work was designed to compare the result of operational parameters including optimum ph and coagulant concentration for chemical coagulation with ferric chloride and alum. also, the...

recent studies show that, inflammation plays an important role in the initiation and progression of atherosclerosis and in the pathogenesis of acute cardiovascular events. there is a possible association between ventricular dysfunction following acute myocardial infarction and high sensitivity c-reactive protein (hs-crp) and uric acid. in this study we assessed the relationship between hs-crp a...

background: polycystic ovary syndrome (pcos), a common endocrine disorder, is associated with infertility, menstrual dysfunction, hirsutism and frequent miscarriages. insulin resistance, as a major cause of pcos, represents a disorder with increase in inflammatory markers and risk of type 2 diabetes. we aimed to investigate whether inflammatory markers, including c-reactive protein and c3 (comp...

in assisted reproduction techniques (art) settings, reactive oxygen species (ros) can be produced from endogenous and exogenous sources during in vitro manipulation. endogenous sources of ros include gametes and embryo, whereas exogenous sources are oxygen tension, light exposure, culture media, and the nature of some protocols, such as centrifugation or cryopreservation. elevated ros productio...

background sepsis is one of the most important causes of morbidity and mortality in the intensive care units (icus). it is difficult to accurately differentiate sepsis from similar diseases rapidly. therefore, it becomes critical to identify any biomarker with the ability of differentiation between sepsis and nonsepsis conditions. the urokinase plasminogen activator receptor has been implicated...

conclusions while the crp value was in patients with acute brucellosis in the current study, the mpv, rdw and leukocyte counts were within the normal range. crp value remains the most valuable inflammatory marker in cases of acute brucellosis. results the follow-up within the year after treatment was examined. the values of age, gender, leukocyte count, c-reactive protein, rdw and mpv were reco...
