We report the complete DNA sequence of the Escherichia coli elt A gene, which codes for the A subunit of the heat-labile enterotoxin, LT. The amino acid sequence of the LT A subunit has been deduced from the DNA sequence of elt A. The LT A subunit starts with methionine, ends with leucine, and comprises 264 amino acids. The computed molecular weight of LT A is 29,673. The A subunit of cho...

In the scope of the evaluation of architecture and technologies for the control system of the E-ELT (European-Extremely Large Telescope) instruments, a collaboration has been set up between the Instrumentation and Control Group of the INAF-OATs and the ESO Directorate of Engineering. The first result of this collaboration is the design and implementation of a prototype of a small but representa...

Orientation of classrooms is an important challenge in architectural design of a school. However, there is a lack of appropriate knowledge about influence of orientation on students’ perception of daylighting in classrooms. This paper presents a questionnaire survey that was conducted to compare students’ perception and satisfaction with daylighting in classrooms of a high school in...

Aim In the present study, we investigated the prevalence of E. coli pathotypes and Shigella sero-groups and their antimicrobial profiles among diarrheic children in Nairobi city, Kenya. Background Although diarrheagenic E. coli pathotypes and Shigella sero-groups are leading causes of diarrhea in children under five years in developing countries, their distribution and antimicrobial resistanc...

Exposure to early life trauma (ELT) is known to have a profound impact on mental development, leading to a higher risk for depression and anxiety. Our aim was to use multiple structural imaging methods to systematically investigate how traumatic stressors early in life impact the emotional brain circuits, typically found impaired with clinical diagnosis of depression and anxiety, across the lif...

Postembryonic development in Caenorhabditis elegans is a powerful model for the study of the temporal regulation of development and for the roles of microRNAs in controlling gene expression. Stable switch-like changes in gene expression occur during development as stage-specific microRNAs are expressed and subsequently down-regulate other stage-specific factors, driving developmental progressio...

Aim/Purpose: This study carried out a systematic review of the literature on artificial intelligence (AI) in English language teaching (ELT). The objective was to delineate current research progress field and further understand challenges. Background: analyzed articles published between 2015 2021. Methodology: qualitative method employed. Five steps were taken steer review. 200 scrutinized; 64 ...

This study aims at investigating the challenges of conducting qualitative research (QLR) from Iranian ELT (English Language Teaching) Ph.D. students’ and ELT faculty members’ viewpoints in the Iranian higher education context. The participants of the study consisted of 100 Ph.D. students majoring in ELT and 50 ELT faculty members. The study followed a mixed-method appro...

This paper reviews current critiques of Kolb’s experiential learning theory. Critiques converge on the belief that the theory places undo emphasis on the role of individual experience at the expense of social, political, and cultural elements of learning. This paper suggests that such critiques are based on a limited, selective, or simplistic reading of the initial theory. The theoretical relat...

With the sudden shift to online teaching with COVID-19 in 2020, ELT professionals and EFL learners found themselves an environment relatively less interaction, distant from their ordinary classrooms. In such a setting, critical aspect of language teaching, oral corrective feedback (OCF), has become even more important for both sides. context emergency distance education, this study focuses on e...
