Thermoplastic polyurethane elastomer (TPUs) were synthesized by poly (oxytetramethylene) glycol (PTMG), hexamethylenediisocyanate (HDI) and 1, 4- Butanediol (BD) at three different molar ratios (1:4.2:3, 1:2.1:1, 3:4.2:1).The effect of stoichiometric balance on the acoustic and damping properties was evaluated. Fourier Transformed Infrared Spectroscopy (FTIR), Differential Scanning Calorimetry (DSC), X-ray Diffractometry (WAXS), Scanning Electron Microscope (SEM), specific gravity, Dynamic Mechanical Thermal Analysis (DMTA) and specific gravity were used to investigate the structures. PUUEs chemical structures were characterized by FTIR. The data on the scattering of the wide-angle X-ray is ascribed to the TPU matrix hard parts phase segregation.The results of DSC and XRD backed up the amorphous and crystalline type of PUEs with 12 and 33 wt % of hard segment (HS), respectively. Changing in molecular structure cases changing in hard segment and specific gravity. This was enhanced in HS, leading to changing in storage modules and damping factor. Damping factor decrease 75% and velocity and acoustic absorption coefficient, in room temperature and 1Hz frequency, changes 200%.

The advent of Severe Acute Respiratory Syndrome Coronavirus 2 (so-called SARS-CoV-2) causing Coronavirus Disease 2019 (so-called COVID-19) occurred in Dec. 2019 in Wuhan, China. Having an inconceivable worldwide contagion, the outbreak was labeled a pandemic by the WHO. Dental services and related professions (including dentists, dental assistants, dental hygienists and the personnel of cleansing, remedial, triage, dental laboratories, radiographic laboratories and other related paraclinicals), facing galore aerosol and droplets, are in the topmost risk groups exposed to the queer virus. This study was fulfilled to round up evidence-based data to break a link at any part of the virus transmission chain in dental services and related professions.

Relevant online databases, as PubMed, MEDLINE, Embase, Scopus, Google Scholar and TripDatabase were searched meticulously and evaluated for relevant published original research papers. Subsequently, to fulfill the investigation, ADA, CDC and WHO websites were reviewed to gain relevant guidelines and protocols. Consequently, 476 resources were included considering the canonical inclusion criteria. For the sake of quality assessment of the resources, an authentic checklist was exploited to score the resources from 1 to 15, wherein the admissible score was 10. After deliberation of resources, 366 of them were excluded and finally, 110 resources were selected and overhauled to attain a comprehensive perception on the subject of the investigation.

Transmission of SARS-CoV-2 includes direct transmission (via droplet and aerosol inhalation) and indirect transmission (via surface and instrument contamination), which can amply occur in dental services and related professions. Therefore, an all-inclusive evidence-based miscellany was rallied on several exigent topics, containing genuine esteem in reputable scientific authorities, to present a consummate report for the dental clinicians and related practitioners, working in the course of the running pandemic.

Contemplating the ongoing crisis, undertaking a set of miscellany elected guidelines and protocols, is indispensable in this vital interval of history to bridle the current pandemic, which has been abridged via this systematic perusal.

In an attempt to add to the current body of research on written corrective feedback (CF), the current study reports on a nine-week intervention, which initially focused on the effect of direct written CF on learners’ use of English articles in their writing and then examined the effect of adding metalinguistic explanation to this CF type; and finally, the effect of learners’ Language Analytic Ability as an individual difference factor is investigated on language development through CF. To do so, this study used a pretest-treatment-posttest- delayed posttest research design and involved 57 intermediate female Iranian EFL learners aged 15-18 in three intact language classes, randomly assigned to the following groups: direct-only CF, direct CF with metalinguistic explanation, and control group. Initially, the findings demonstrated positive effects for direct written CF provided to learners’ writing, though the short-term benefit was more evident and statistically significant. The results also revealed a positive gain pattern through time for learners that received metalinguistic explanation, which supports the provision of such information along with written CF in language classrooms. Finally, learners’ language analytic ability was seen to be predictive of short-term and long-term learner gains when received metalinguistic explanation. The findings suggest that metalinguistic explanation provided as part of the feedback to language learners’ writing is conducive to a higher level of cognitive engagement and leads to better learning outcomes.

The purpose of this study is the modeling a fibrous filter with random fibers, the simulation and the analysis of the effect of brownian and thermophoretic forces on the cupture of nanoparticles in the shallow fibrous micro-filters. In the present study is used from the one-way coupling, according to the motion of the particles is due to the motion of the base fluid. On this basis and in the euler approach,  the governing equations on the base fluid flow and heat transfer and in the lagrangian approach, differential equations governing on the dynamics of the particles (discrete phase) are obtained and solved numerically. In the lagrangian approach, the motion of nanoparticles and their Captured is simulated by using of the particle tracking and considering brownian and thermophoretic forces. The analysis of these equations was performed in view of euler and lagrange, considering small size in the finite element method (FEM). Next, a suitable method is provided for the numerical solution of the equations governing on the motion of nanoparticles and the simulation of the particle cupterd mechanisms, according to the type of equations and effective forces on the nanoscale. then, the results of this simulations are compared and validated with the previous research results. Finally, the results is provide for different gradients temperature, different size of the fiber and nanoparticles, density and fiber filtration layer in the form of design and efficiency diagrams. The results show that the dominant mechanism in the cupterd of particles below 100 nm is brownian diffusion. In this particles range, thermophoretic phenomenon has a little effect on the cupture of nanoparticle by filter fibers. Also, interception mechanism is more effective from brownian diffusion and thermophoretic mechanisms.
