Sanitisation has become a major component of everyday life, with emphasis on the hands and surfaces. The face remains unsanitised. This is due to the lack of an acceptable sanitiser. The use of masks has been implemented in order to protect the spread of the pathogens by covering the face, however there remain issues associated with the use of PPE.. The face remains a harbour for upper respiratory tract infections, with constant deposition and replication of microbes. With SARS-CoV-2 being so prominent, it was postulated that there is an inoculum dose-dependant relationship with severity. By reducing microbial load of the face, the risk of both infection and severity of infection are reduced. HOCl has proven antimicrobial and antiinflammatory activity and was tested for efficacy against SARS-CoV-2, demonstrating a 99.99% reduction (50ppm; 1 min contact). A facial sanitiser, added to the arsenal of hand sanitisers and masks, further improves protection and prevention against SARS-CoV-2. The advantages of regular sanitising of the face and mask include a reduced level of microbial contamination, reduced risk of biofilm formation, and respiratory tract and skin infections. HOCl was reviewed as a face and face mask sanitiser, concluding that it was an ideally suited product.

The new method is put forward for machining bigger holes of carbon fiber reinforced plastics (CFRP) in the face of the existent problems. The core drill is applied to machine CFRP from two end-faces according to regular order. The thrust is less than felted intensity between adjacent layers of CFRP in their whole process. Through special experiment, the method is not only economical but also convenient. The finishing workpieces have not defects such as burrs, avulsion and delamination. In addition, its precision and efficiency are very satisfactory to manufacturer.

Introduction. Review of the literature indicates the relationship between upper airways patency and lower jaw morphology. Aim of the study. To design multidimensional models to describe morphological relations of the linear and angular dimensions of hard tissues of the lower facial skeleton and the cervical spine (independent variables) with the linear dimensions of the upper respiratory tract (dependent variables). The obtained models took into consideration the age, gender and the skeletal Class I and III of the evaluated individuals. Material and method. The patients represented two skeletal classes: I (n = 97; 42.4%) and III (n = 53; 23.1%). Prior to orthodontic treatment, lateral cephalometric radiography (LCR) was performed in all patients. The obtained cephalometric measurements were evaluated statistically. Results. The statistical analysis pointed to significant differences between variables of the URT and dimensions of the facial skeleton and the cervical spine. It also revealed significant differences between variables of the URT and dimensions of the facial skeleton and the cervical spine. The independent variable Co-Gn emerged as an important predictor in regression of the nasopharynx. The anteroinferior height of the face and mandibular inclination were the factors relevant for oropharynx. Variables of the cervical spine were significant predictors in laryngopharyngeal models. Conclusions. The results illustrating morphological interrelations between the lower face and dimensions of the URT air space may prove helpful in planning orthodontic treatment, with or without teeth extraction, as well as orthognathic surgeries.

Introduction: Coronavirus belongs to a family of viruses that can cause symptoms such as pneumonia, fever, shortness of breath and lung infection. On December 29, 2019, the World Health Organization (WHO) coined the term New Coronavirus 2019 to refer to a coronavirus that affects the lower respiratory tract of patients with pneumonia in Wuhan, China. The new coronavirus was first identified in Wuhan, among a number of patients with an unknown form of viral pneumonia who also had a history of Huanan seafood market. Materials and Methods: In this study, the websites of PubMed, Google Scholar, SID, and Magiran were searched and related articles were reviewed. Results: Symptoms of COVID-19 occur after a period of 2 to 10 days and the period of symptoms resulting in death of patients varied between 6 to 41 days. Common symptoms at the onset of the disease are fever, cough, and fatigue. Each carrier is reported to infect an average of 3.77 others. Conclusion: Regarding the way of transmission of viral diseases of the upper respiratory tract, such as COVID-19, i.e., the transmission by respiratory droplets as well as close communication between individuals, solutions have been recommended by experts. Researchers are suggesting not touching the T-zone on the face, using a mask and following the principles of social distancing are the most effective ways to control the disease. Due to the lack of definitive treatment or effective vaccine for COVID-19 so far, following these principles has a significant role in combating this pandemic.

Spraying Process

This work focuses on failure mode maps of sandwich panels exposed to bending load, which were produced using a polyurethane spraying process. This process allows for an automated production of sandwich panels omitting a separate bonding step of the face sheets to the core. The investigated sandwich panels consisted of carbon fiber reinforced face sheets in various configurations, and four different core structures of aluminum foam or Nomex honeycomb. After production, measurements of the pores inside the core foam structures, the fiber package thickness inside the face sheets, and the density homogeneity of the core structure were made using X-ray computed tomography. The failure mode maps were based on the individual mechanical properties of the face sheets and the core, determined by mechanical testing. The critical forces determining the failure modes were partially modified to fit the application on foam core structures and face sheets with a porous matrix. The verification of the failure modes was performed with four-point bending tests. Since all tested configurations of sandwich specimens were produced using the same process route, the applied models for the creation of the failure mode maps could be verified for numerous parameter combinations. Except for two parameters with inconstant properties, the failure modes determined by the failure mode maps matched the observed failure modes determined by the bending tests.

This study includes the identification of parameters for the characterization of the structural behavior of thin plates composed of geopolymer mortars structured with bi-directional carbon fiber mesh. Initially, facade projects, designed by offices in São Paulo using the concepts of sustainable architecture, promoting the use of geopolymeric materials are presented. Then shows the composition of the geopolymer mortar used in this study and the characterization of their mechanical properties. As part of the experimental program, this study evaluates the plate bending behavior and the effect of pull-out test and push-off test of the metallic inserts. It has used the advanced features of ATENA computational mechanics program, which correspond to the state of the art in Finite Element Modeling of reinforced concrete structures, which allow the calibration of the mathematical model based on information from the experimental program. The numerical results showed satisfactory adhesion with the experimental results. It also has emphasized the importance of validation of these results on the determination of loads collapse of structural elements, as is reflected positively in the field of Structural Engineering in the face of increasing advancement of surface modeling programs and technological innovations in according to sustainability criteria for constructions materials.

<div class=""abs_img""><img src=""[disp_template_path]/JRM/abst-image/00260004/03.jpg"" width=""200"" /> HVAC assembly line</span></div> Since Denso started its Flexible Manufacturing System (FMS) in the mid-1970s, we have continued to develop it in order to stay competitive in the face of market fluctuations. In this paper, we present a typical new production system that was developed at the end of the 20th century. One characteristic of this system is that it has a longer life and lower facility life cycle cost than do other production systems in existence. We think this system has high potential in terms of production innovations. Since one of the most important devices for FMS is the robot, we hope this paper will be a guide for new production systems and new device development. </span>
