Structure prediction of the 5' non-translated region (NTR) of four iflavirus RNAs revealed two types of potential internal ribosome entry site (IRES), which are discriminated by size and level of complexity, in this group of viruses. In contrast to the intergenic IRES of dicistroviruses, the potential 5' IRES structures of iflaviruses do not have pseudoknots. To test the activity of one of thes...
Exposure to whole-body vibration (WBV) is an occupational hazard for operators of industrial vehicles, such as earth-moving machines. Quantification of WBV exposure in terms of impact on health forms one aspect of the Standard ISO 2631-1 (1997). Regarding assessment of risk to health, ISO 2631-1 (1997) states that if WBV components below 1 Hz are not ;relevant nor important' then they can be ex...
The environment is one of the factors that may influence occupants’ perception floor vibration and assessment serviceability. In this study, laboratory tests were conducted on a 3-ply CLT floor. Occupants’ serviceability under human-induced was investigated. Virtual reality (VR) technique used as research method, simulating two common environments in life. First, correlation between annoyance r...
OBJECTIVES The purpose of this study was to determine exposure to whole-body vibration (WBV) and mechanical shock in rural workers who use quad bikes and to explore how personal, physical, and workplace characteristics influence exposure. METHODS A seat pad mounted triaxial accelerometer and data logger recorded full workday vibration and shock data from 130 New Zealand rural workers. Persona...
Abstract Varroa destructor parasitism is associated with extreme honey bee ( Apis mellifera ) colony losses in the northern hemisphere. causes severe damage, including a decrease longevity and immunosuppression, acts as vector for viruses, such Deformed wing virus (DWV-A). The surveillance of viral pathogens V. samples essential to assess risks emerging virulent variants (such VDV-1) evaluate t...
Dance challenges are going viral in video communities like TikTok nowadays. Once a challenge becomes popular, thousands of short-form videos will be uploaded within couple days. Therefore, virality prediction from dance is great commercial value and has wide range applications, such as smart recommendation popularity promotion. In this article, novel multi-modal framework that integrates skelet...
Honeybees originating from 10 different countries (Austria, Poland, Germany, Hungary, Slovenia, Nepal, Sri Lanka, the United Arab Emirates, Canada, and New Zealand) located on four continents were analyzed for the presence of deformed wing virus (DWV) nucleic acid by reverse transcription-PCR. Two target regions within the DWV genome were selected for PCR amplification and subsequent sequencing...
Deformed wing virus (DWV) is considered one of the most damaging pests in honey bees since the spread of its vector, Varroa destructor. In this study, we sequenced the whole genomes of two virus isolates and studied the evolutionary forces that act on DWV genomes. The isolate from a Varroa-tolerant bee colony was characterized by three recombination breakpoints between DWV and the closely relat...
زمینه و هدف: بدن ما در تمامی وسایل نقلیه با ارتعاش تمام بدن مواجه است. ارتعاش سبب اختلالات اسکلتی – عضلانی در اندامهایی مانند شانهها، گردن و کمر میشود. روش بررسی: مواجهه مسافرین در وضعیت نشسته در 11 قطار در خطوط فعال مترو تهران در زمان انجام مطالعه بر اساس روشهای [i]rms و[ii]vdv استانداردهای bs 6841 و iso 2631-1 و با دستگاه ارتعاش سنج و آنالیزور svan 958 انجام گردید. یافته ها: نتایج حاصل ...
