This study aimed at investigating the difference of integrated writing task of the TOFEL iBT candidates in comparison with independent writing task on Iranian EFL learners writing performance. The initial population for the study was 50 junior EFL students. To get more homogeneity, participants were selected among those who were studying in the third year of university in EFL major. They were m...

In patients with so-called roentgenologically occult intraluminal lung tumours, an accurate assessment of tumour size, its location and peribronchial tumour extent is important prior to any intraluminal bronchoscopic therapy (IBT) with curative intent. In twenty patients with so-called occult early-stage lung cancers, clinical outcome was compared to high resolution computed tomography (HRCT) f...

The butyrate derivative isobutyramide (IBT) increases fetal hemoglobin (HbF) in patients with beta-hemoglobinopathies, but little is known about its usefulness for prolonged therapeutic use. We treated 8 patients with transfusion-dependent beta-thalassemia with 350 mg/kg of body weight per day of oral IBT for 126 to 384 days. During the trial period, the hemoglobin level was maintained between ...

toefl ibt has turned recently heads to the impacts language tests can have on language learning. since error analysis-based instruction has gained a new life with the advent of the computer analysis of the learner’s language, the researchers of this study embarked on examining a sample of integrated and independent writing tasks of 45 iranian toefl ibt candidates in order to identify and classi...

BACKGROUND Type 2 diabetes is a chronic, progressive disease with a multi-faceted pathophysiology. Beyond the known defects of insulin resistance and beta-cell insufficiency, derangement of incretin hormones normally produced from the gut wall in response to food intake play an important role. In recent years, the 'incretin-based' therapies (IBTs) have been developed to address hyperglycemia th...

A real option on a commodity is valued using an implied binomial tree (IBT) calibrated using commodity futures options prices. Estimating an IBT in the absence of spot options (the norm for commodities) allows real option models to be calibrated for the first time to market-implied probability distributions for commodity prices. Also, the existence of long-dated futures options means that good ...

In this study 253 serum samples from cattle showing respiratory disorders were tested by confirmatory Western Immunoblotting test (IBT), complement fixation (CFT) and competitive enzyme linked immunosorbent assay (c-ELISA). Two (0.8%) out of found to be positive two doubtful CFT while 7 (2.8%) as 25 (9.9%) them c-ELISA. On the other hand, a core profile antigenic bands needed identified at 110,...

This report shows methods to fabricate polydimethylsiloxane (PDMS) microfluidic systems for longterm (up to 10 day) cell culture. Undesired bubble accumulation in microfluidic channels abruptly changes the microenvironment of adherent cells and leads to the damage and death of cells. Existing bubble trapping approaches have drawbacks such as the need to pause fluid flow, requirement for externa...
