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...

Chikungunya virus (CHIKV) infection is one of the most challenging human Arboviral infections with global significance and without any specific antiviral. In this investigation, 1-[(2-methylbenzimidazol-1-yl) methyl]-2-oxo-indolin-3-ylidene] amino] thiourea (MBZM-N-IBT) was synthesised as a molecular hybrid of 2-methyl benzimidazole and isatin-β-thiosemicarbazone and its anti-CHIKV property was...

We compared the effects of three treatment approaches on preschool-age children with autism spectrum disorders. Twenty-nine children received intensive behavior analytic intervention (IBT; 1:1 adult:child ratio, 25-40 h per week). A comparison group (n=16) received intensive "eclectic" intervention (a combination of methods, 1:1 or 1:2 ratio, 30 h per week) in public special education classroom...

OBJECTIVE The aim of this study was to assess the actual effectiveness of long-term phlebotomy by comparing histological improvement (HI) in 69 Caucasian HCV-RNA-positive CHC patients undergoing phlebotomy or receiving an interferon-based therapy without virological response [nonresponders to interferon therapy(IBT-NR)]. METHODS HI was defined by at least one point reduction of the staging sc...

Beak trimming is necessary in commercial broiler breeders to prevent or decrease trauma as they mature. Two common beak-trimming methods were evaluated by early performance comparison with nontrimmed chicks (NBT). The robotic electrocautery device (ECD) trims and cauterizes the beak tip. The robotic infrared beak-trimming device (IBT) applies an infrared light beam to destroy the live basal tis...

the interaction between isatin-β-thiosemicarbazone (ibt) and calf thymus dna (ct-dna) was investigated in physiological buffer (ph 7.4) using neutral red (nr) dye as a spectral probe by uv–vis absorption and fluorescence spectroscopy, as well as viscosity measurements. the ibt is stabilized by intercalation in the dna ( k [ibt –dna] =1.03×105 m−1), and displaces the nr dye from the nr–dna comple...

Taking the position that writing can be an important skill to foster knowledge building pedagogy, this article explores vocabulary as a supportive tool for this purpose. Having this in mind, a compilation of conceptually loaded vocabularies pertaining to seven discourse communities was developed, two of which were given to a group of L2 writers to investigate the implications of phraseology for...

In this study, I examine several different approaches to identifying entities and relations in sentences. I compare three different strategies to learn entities and relations. The first uses just local classifiers, the second uses local classifiers with integer linear programming (ILP) inference, and the third uses inference based training (IBT) and evaluates using ILP inference. My experiments...

Developing rating scales for assessing interactional performance is demanding since it is a relatively complicated procedure. The present study investigated the psychometric characteristics of the CAP rating scale (Wang, 2015) for assessing interactional competence at micro-level. To this end, 160 Iranian intermediate EFL learners were selected based on their performance on TOEFL iBT test from ...

Studying perceptions of stakeholders and beneficiaries is important in framing the system improving outcome. This study sought to appraise graduates TVET school managers vis-à-vis Industrial-Based Training (IBT) use schools Rwanda. A mixed method was used, data were collected from both managers. Research instruments questionnaire surveys follow-up in-depth interviews. Findings revealed that 83....
