Acoustical Evaluation and Comparison Between Two Classroom Types in Erbil

In order to acquire an effective learning process in lecture halls with good speech intelligibility, good acoustical performance is essential. Inappropriate acoustic quality in classrooms reduces learning quality experience and can induce emotional disorders among students. The aim of this study is to evaluate and compare acoustic quality in two classrooms to determine their performance in terms of the learning process, at two types of theoretical halls at the Faculty of Engineering, Tishk International University. The calculation for the acoustical parameters of Reverberation Time (RT, T30), Speech Transmission Index (STI) and sound pressure level (SPL) for the selected educational spaces (classrooms) by simulation software (ODEON) were conducted, and the results were compared with acoustical requirements and guidelines for educational spaces. The results indicated that the closer the receiver (i.e., learner) is to the source (i.e., the lecturer), the lower the reverberation time; conversely, the further students (receivers) are from the teacher (source), the lower the STI and SPL values. This is mainly because of teacher’s direct sound. It can be concluded that the acoustic quality of flat halls is better than raked halls for the learning process

Rabies virus strains circulating in Bhutan: implications for control.

We report a molecular epidemiological study of rabies virus strains circulating in animal populations in Bhutan, and investigate potential origins of these viruses. Twenty-three rabies virus isolates originating from dogs and other domestic animals were characterized by sequencing the partial nucleoprotein (N) gene (395 bp). Phylogenetic analysis was conducted and the Bhutanese isolates were compared with rabies viruses originating from other parts of the world. Phylogenetic analysis showed that Bhutanese isolates were highly similar and were closely related to Indian strains and South Asian Arctic–like–1 viruses. Our study suggests that the rabies viruses spreading in southern parts of Bhutan have originated from a common ancestor, perhaps from the Indian virus strain.

Religious beliefs and entrepreneurial behaviours in Africa: a case study of the informal sector in Uganda

Religion plays a major role in Africa’s polity and its influence on the business landscape of the continent has been acknowledged in literature. This study contributes to the discourse by investigating and explaining how religious beliefs shape entrepreneurial behaviours in Uganda’s informal sector. Using a qualitative methodology, we explored how entrepreneurs in the context use or adopt religious beliefs in their entrepreneurial activities. By spanning a diverse set of entrepreneurial activities in the informal sector- food vendors, fabricators, hawkers, and recyclers among others, we conducted 49 in-depth interviews. Our findings reveal that the entrepreneurs relied on their religious beliefs in defining and coping with a penurious context. Further to this, we explain how religious beliefs galvanize business behaviours and calibrate the entrepreneurial identities of respondents in the context. To facilitate future work, the study highlights how knowledge gaps in the cultural and social setup of the informal economy will produce new insights in entrepreneurship research. It concludes by guiding policy makers and educators to engage and involve faith based institutions in the entrepreneurship promotion agenda

The Fruit Flies (Diptera, Tephritidae) in Bhutan: New Faunistic Records and Compendium of Fauna

Based on a field survey from 2017, twenty-three species are reported from Bhutan for the first time: Acroceratitis ceratitina, A. hardyi, Anomoia approximata, Bactrocera connecta, B. latifrons, B. nigrifacia, B. syzygii, Campiglossa sororcula, Cecidochares connexa, Dacus jacobi, Gastrozona fasciventris, Hoplandromyia antelopa, Lenitovena ultima, Ptilona confinis, Rioxoptilona dunlopi, R. formosana, R. vaga, Spathulina acroleuca, Themara yunnana, Trypeta indica, Zeugodacus apiciflavus, Z. diversus, and Z. fereuncinatus. Four species of the genera Cornutrypeta, Hemilea, Morinowotome, and Vidalia are also recorded for the first time, but the precise determination to species needs additional study and material. As the result, 71 species is listed from Bhutan by far. Their taxonomic position and key characters are discussed. Illustrations for most of the newly recorded species are given

HLA-DQA1*05 carriage associated with development of anti-drug antibodies to infliximab and adalimumab in patients with Crohn's Disease

Anti-tumor necrosis factor (anti-TNF) therapies are the most widely used biologic drugs for treating immune-mediated diseases, but repeated administration can induce the formation of anti-drug antibodies. The ability to identify patients at increased risk for development of anti-drug antibodies would facilitate selection of therapy and use of preventative strategies.This article is freely available via Open Access.

Finishing the euchromatic sequence of the human genome

The sequence of the human genome encodes the genetic instructions for human physiology, as well as rich information about human evolution. In 2001, the International Human Genome Sequencing Consortium reported a draft sequence of the euchromatic portion of the human genome. Since then, the international collaboration has worked to convert this draft into a genome sequence with high accuracy and nearly complete coverage. Here, we report the result of this finishing process. The current genome sequence (Build 35) contains 2.85 billion nucleotides interrupted by only 341 gaps. It covers ∼99% of the euchromatic genome and is accurate to an error rate of ∼1 event per 100,000 bases. Many of the remaining euchromatic gaps are associated with segmental duplications and will require focused work with new methods. The near-complete sequence, the first for a vertebrate, greatly improves the precision of biological analyses of the human genome including studies of gene number, birth and death. Notably, the human enome seems to encode only 20,000-25,000 protein-coding genes. The genome sequence reported here should serve as a firm foundation for biomedical research in the decades ahead
