در این تحقیق به مقایسه تحلیلی و عددی آبشار جریان برگشتی مدل R با آبشارهای Q QI سیستم‌­های چندجزیی پایدار پرداخته می‌­شود. راستا برای اولین بار کدهای جهت طراحی منظور کد نرم‌افزار متلب نوشته شده‌­اند. نتایج نشان می‌­دهد که دو جزء 1k 2k از خوراک Nc جزء، تعداد معدودی قابل تعریف است همگی حالات خاصی می­‌باشد. هم‌­چنین یافته‌­ها مجموع مقدار برش جزیی همیشه برابر یک است. طریق داده می‌­شود صورتی میانگین ...

Single-walled carbon nanotubes (SWCNTs) involving polyethylene glycol (PEG) and polyethyleneimine (PEI), which contain amines, were produced analyzed using X-ray diffraction (XRD), UV–vis spectroscopy, Raman spectroscopy (RS), transmission electron microscopy (TEM) for the spectral structural analyses of PEG-PEI-SWCNTs. PEG-PEI-SWCNTs demonstrated peaks at 300.98 nm, have a broad peak 2θ = 23.5...

Feeding-related adverse events after percutaneous endoscopic gastrostomy (PEG) such as aspiration pneumonia can impede the use of PEG. Percutaneous endoscopic transgastric jejunostomy (PEG-J) using large-bore jejunal tubes with gastric decompression function may improve outcomes by circumventing gastric passage during enteral nutrition and improving drainage of excessive gastric secretions. Thi...

This study prepared shape-memory thermoplastic epoxy (TEP)-polyethylene glycol (PEG) filaments for the first time, and heat-stimuli controllability of shape memory function was innovatively endowed by adding PEG in an environmentally friendly way. regulates glass transition temperature PEG-modified (TEP–PEG) without interfering with polymerization reaction epoxy. The melt spinning TEP–PEG is al...

Foam thin liquid films (TLF) and monolayers at the air-water interface formed by DMPC mixed with DMPE-bonded poly (ethylene glycol)s (DMPE-PEG(550), DMPE-PEG(2000) and DMPE-PEG(5000)) were obtained. The influence of both (i) PEG chain size (evaluated in terms of Mw) and mushroom-to-brush conformational transition and (ii) of the liposome/micelle ratio in the film-forming dispersions, on the int...

Current pegylated interferon-α (PEG-IFN) treatment for chronic hepatitis B (CHB) e-antigen (HBeAg)-positive patients are suboptimal, and effective ways of improving PEG-IFN treatment efficacy are needed.This retrospective cohort study compared the efficacy of a PEG-IFN stepwise optimization treatment (PEG-IFN SOT) strategy with that of a 48-week PEG-IFN standard therapy (PEG-IFN ST) in HBeAg-po...

When liposomes, as a superior drug carrier, are injected intravenously, active liposomes as medicines require polyethyleneglycol (PEG) as a modification tool around the liposomal membrane. PEG modification of a liposome forms a fixed aqueous layer, and the trapping by cells of the reticuloendothelial system (RES) is avoided. Hence, PEG-modified liposomes have long circulation in the bloodstream...

Brazilian Guidelines to HCV treatment (2007) recommended that the first choice treatment for patients with chronic hepatitis C (CHC) and genotype 2 or 3 is interferon alpha (IFN) plus ribavirin (RBV) for 24 weeks. The aim of this study is compare the cost and effectiveness to Hepatitis C treatment in patients with genotype 2 or 3 of peginterferon alpha (PEG) as the first choice of treatment wit...

The aim of the study was to assess the role of salicylic acid (SA) and abscisic acid (ABA) in osmotic stress tolerance of wheat seedlings. This was accomplished by determining the impact of the acids applied exogenously on seedlings grown under osmotic stress in hydroponics. The investigation was unique in its comprehensiveness, examining changes under osmotic stress and other conditions, and t...
