Reactive power management plays an essential role in the secure operation of the power system as an ancillary service. Although in electricity markets, the particular attention is paid to active power, the reactive power also plays an important on total generation costs of electricity. On the other hand, as it is mainly confined to local consumption, to avoid market power and maintain the se...

background fenton (fe2+ and h2o2) and modified fenton (fe3+ and h2o2) are two popular methods used in advanced oxidation processes (aop) and degradation of persistent organic pollutants (pops), such as dye compounds. in these processes, fe2+ and fe3+ as catalysts and h2o2 as the oxidizing agent are added to the reactor. objectives the aim of the current study is to assess the abovementioned met...

background: among different pollutants released into the environment, dyes are considered as one of the most dangerous contaminants. in recent years, magnetic nanomaterials have attracted much attention for their dye removal capacity. the aim of this study was to explore the adsorption kinetics of an anionic dye (reactive orange 13 (ro)) by nife2o4 nanoparticles (nife2o4 nps) under various cond...

introduction: the use of exercise along with herbal supplements is one of the recommended methods for controlling obesity and its complications, but its effects have been controversial due to the diversity of training programs and also herbal supplements. hence, the objective of this study was to investigate the effects of 10 week ginger and progressive resistance training on c-reactive protein...

neuroserpin, a member of the serine proteinase inhibitor (serpin) superfamily, is known to be a neuroprotective factor in the focal ischemic stroke followed by reducing the microglial activation. neuroserpin is a protein rich of methionine residues that can scavenge the free radical species which may increase its neuroprotective effect. on the other hand, the oxidative modifications of the amin...

background: combination of glycation and oxidation is associated with diabetes mellitus. the aim of this study was to clarify the effect of glycated proteins in presence of transition metal ions on production of reactive oxygen species (ros) in rat hepatocyte suspension.  methods: glycated albumin was prepared by incubation of bovine serum albumin with 100 mm glucose in 0.3 m phosphate buffer a...

background: colors make many problems and these are major sources of environmental pollution. therefore, this wastewater should be treated before discharge to environment to reduce the environmental threats. adsorption is one of the usual processes for color removal from wastewater. nanotube s are new adsorbents with extend application for adsorption of different compounds. aim of this study wa...

background and aims. recent epidemiological studies have shown that individuals with periodontitis have a significantly higher risk of developing coronary heart disease, which might be attributed to the complex microbiota in the dental plaque. periodontopathogens have been reported as risk factors for cardiovascular disease. this study evaluated association of chronic periodontitis and periodon...
