Detection of Metallic and Non Metallic Objects on a Conveyor Belt Using PLC Logics, HMI Screen, VFD

© ASEE 2015This project was created to control and monitor movable parts on the conveyor belt by a Human Machine Interface (HMI). In our application, we separate metallic and non-metallic objects. This application could be used in pharmaceutical, electronic industries or any industry which deals with metals/plastic. An eye sensor and a proximity sensor have been used to detect the non- metallic and metallic objects respectively. According to that the counter counts non-metallic and metallic objects and display the value on the HMI, whenever a metallic object is detected Air cylinder pushes it out of the conveyor belt and allows non-metallic objects to reach till the end of conveyor. PLC with series FX3U-16MR/ES manufactured by Mitsubishi is used in this project. This logic can handle a series of metallic and non-metallic objects. To control the speed of the conveyor VFD (Variable Frequency Drive) is programmed and used.E-Designer-7 software is used to design the screen. GX Developer software has been used to create PLC logic

Shared Antigen-specific CD8⁺ T cell Responses Against the SARS-COV-2 Spike Protein in HLA A*02:01 COVID-19 Participants

We report here on antigens from the SARS-CoV-2 virus spike protein, that when presented by Class I MHC, can lead to cytotoxic CD8⁺ T cell anti-viral responses in COVID-19 patients. We present a method in which the SARS-CoV-2 spike protein is converted into a library of peptide antigen-Major Histocompatibility Complexes (pMHCs) as single chain trimers that contain the peptide antigen, the MHC HLA allele, and the β-2 microglobulin sub-unit. That library is used to detect the evolution of virus-specific T cell populations from two COVID-19 patients, at two time points over the course of infection. Both patients exhibit similar virus-specific T cell populations, but very different time-trajectories of those populations. These results can be used to track those virus-specific T cell populations over the course of an infection, thus providing deep insight into the variations in immune system trajectories observed in different COVID-19 patients

Genetic Variability of Human Respiratory Syncytial Virus A Strains Circulating in Ontario: A Novel Genotype with a 72 Nucleotide G Gene Duplication

Human respiratory syncytial virus (HRSV) is the main cause of acute lower respiratory infections in children under 2 years of age and causes repeated infections throughout life. We investigated the genetic variability of RSV-A circulating in Ontario during 2010–2011 winter season by sequencing and phylogenetic analysis of the G glycoprotein gene

Practitioners section - Information and communication technology developments in asthma management: A systematic review

This review aims to explain the progress of information and communication technology (ICT) applications in asthma management. Appropriate literature was printed out from the bibliographic databases and library source using relevant key phrases of ICT and asthma. The ICT developments from simple to complex modules to augment the conventional methods of asthma care with a caution of excessive reliance upon technology were discussed. However, it should be noted ICTs are for maximizing the human clinician's own ability to receive and process information as well as providing unique opportunities for patients, physicians, pharmacists and researchers
