Abstract Most oil reservoirs in China have entered the stage of high water cut. Affected by heterogeneity reservoir, flow dominance channel is easily formed between injection-production wells plane direction such reservoirs, and phenomenon channelling intensified. Therefore, a numerical simulation study nitrogen foam flooding carried out this paper. According to reservoir characteristics target...

the conversion process of heavy hydrocarbons to the valuable products such as gasoline is an important operation in the oil refineries.one important process is the “fluidized catalytic cracking” (fcc).feed injection in fcc process has an important role in the selectivity and properties of the products.performance of the feed injection system is dependent on the atomizers.the size and contributi...

With the exception of some recent applications of the isotope technique (l), studies concerned with endocrine influences over nitrogen metabolism have depended largely on the use of the conventional nitrogen balance technique or on measurements of tissue nitrogen. While these methods have yielded valuable information about over-all changes in nitrogen metabolism, they do not offer much opportun...

introduction: broadcast fertilization method increases fertilizer losses while results in lower nutrient absorption by plant roots. fertigation is an effective method to increase water and fertilizer efficiency and to reduce the losses of nitrogen. moreover, it allows farmers to apply the nutrients in splits and few amounts in response to crop needs. in the present study, a field experiment was...

Gasoline compression ignition in diesel engines has been proposed order to meet increasingly stringent emission regulations without sacrificing efficiency. In this study, a six-cylinder heavy-duty engine was operated mixing controlled gasoline mode investigate the influence of fuels and injection strategies on combustion characteristics, emissions, thermal efficiencies. Fuels, including ethanol...

The effects of infusion of clonidine, an a2-adrenergic agonist, on plasma insulin-like growth factor-I (IGF-I) concentrations were investigated with a single growth hormone (GH) injection in pigs. Four barrows were subjected to four treatments: saline infusion with a vehicle injection, clonidine infusion (0.5 nmol/kg/min for 8 h) with a vehicle injection, saline infusion with a bovine GH (bGH:1...

BACKGROUND The effect of digoxin administration on the serum concentration of the cardiac troponin I (cTnI) has not been reported to date in equidae. This study was therefore designed to evaluate the effect of digoxin on cardiac cell damage in donkeys (Equus asinus) as assessed by cTnI, acid-base and electrolyte balance and haematobiochemical profiles. Ten clinically healthy donkeys were given ...

The potential action of cytotoxic agents such as alkylating drugs and antimetabolites on the immune response and inflammatory process has suggested their trial in the treatment of rheumatic diseases. Nitrogen mustard was tried initially both by intravenous and intra-articular injection in the therapy of rheumatoid arthritis and gave variable responses (Jimenez Diaz, 1951; Jimenez Diaz, Lopez Ga...

hemiscorpius lepturus is the most dangerous scorpion species, endemic in khuzestan province and other southwestern areas of iran, causing morbidity and mortality in children and adults. the efficacy of the antivenom for reversal of manifestation caused by venom of this scorpion is a controversial issue. in the present work, h. lepturus venom (1500 µg/kg) was subcutaneously injected into two ...

KubeSovA, K., J. bAlIK, o. SedlAR and l. PeKlovA, 2014. effect of ammonium fertilization by CulTAN method on dry matter accumulation and dynamics of nitrogen uptake by maize. Bulg. J. Agric. Sci., 20: 563-570 The aim of this trial was to assess the influence of nitrogenous fertilization by CULTAN (Controlled Uptake Long Term Ammonium Nutrition) method on the dynamics of above-ground biomass dry...
