Sulfate particles play a key role in the air quality and the global climate, but the heterogeneous formation mechanism of sulfates on surfaces of atmospheric particles is not well established. Carbonates, which act as a reactive component in mineral dust due to their special chemical properties, may contribute significantly to the sulfate formation by heterogeneous processes. This paper present...

BACKGROUND Patients with pulmonary venous hypertension (PVH) secondary to left heart disease can be further classified according to their hemodynamic profile: pulmonary hypertension (PH) in proportion to the pulmonary capillary wedge pressure (PCWP) and PH out of proportion to the PCWP or reactive PH. Currently, there are no measures that enable prediction of the development of reactive PH in p...

conclusions considering the simplicity and efficiency of zero valent iron powder, this method is recommended for removing azo dyes from aqueous environments. results the results of this research showed ph = 3 and contact time = 120 minutes, increasing the zvi dose from 200 to 5000 mg/l in 100 mg/l dye concentration, increased the adsorption efficiency from 36.78% to 97.57%. rr-198 removal follo...

Hydrocarbon Processing Industries (HPIs) emit large amounts of highly reactive hydrocarbons and Nitrogen Oxides to the atmosphere. Such simultaneous emissions of ozone precursors result in rapid and high yields ozone (O3) formation downwind. The climate of the Middle East has been shown to be favorable for O3 formation in summer. There are also vast activities in processing oil and gas in this ...

background and objective: brucellosis is a main transmittable zoonotic disease, which is endemic, and a common health burden in iran. adenosine deaminase (ada) is an essential enzyme which is involved in purine metabolism and its role in immune system is very important. the aim of this study was to determine serum changes of ada and c-reactive protein (crp) levels in patients with brucellosis. ...

conclusions crp, a well-known acute phase reactant that increases rapidly in various inflammatory processes, can be accepted as a strong predictor in classifying different grades of the disease, and treatment can be reliably planned according to this classification. results mean crp levels of groups were found to be significantly different, 18.96 mg/l in group i, 133.51 mg/l in group ii, and 23...

background: allergens are mostly composed of glycoprotein structures. it is believed that glycan-specific antibodies may lead to false-positive reactions in immunoassays. in this study we investigated the glycosylation state of grape allergens as well as the presence of antibodies to cross-reactive carbohydrate determinants (anti-ccds) in sera from grape-sensitive individuals. methods: grape ex...

conclusions considering that no significant difference was found in the proven vitamin a side effects, due to the increase in crp, frequent clinical and biochemical controls are required along with vitamin a supplementation. patients and methods this study was a double blind randomized clinical trial. in the main study, vitamin a (as retinyl palmitate) was given to 35 multiple sclerosis (ms) pa...

During normal operation, doubly-fed induction generator (DFIG) can generate certain range of reactive power according to the requirements of the power grid. According to the active power order from power dispatching center, a kind of wind turbines scheduling solution which also suits the actual operation situation of “three-north” area wind farms in China is proposed. This solution makes it pos...
