Objective To look around the audio efficiency, sound absorption as well as other noises decrease transformation methods inside a sounds workshop handover handle room. Approaches Throughout 12 2021, through the work-related health investigation and on-site testing of the handover manage area of an noise working area, the cause of abnormal noises were examined, along with the change layout scheme to reduce sounds ended up being proposed and also the effect was analyzed. Outcomes Ahead of the change for better, the height regularity group noise intensity of your noise class handover control area ended up being 112.7 dB (Any), as well as the maximum regularity was One thousand Hz. Soon after noises decline, the actual theoretical calculated manage benefit had been Sixty one.2 dB (The), and the measured noise depth ended up being 59.8 dB (A) . Bottom line The sound power of the handover management room can be lowered right after sound reduction, which is in line with the contact reduce specifications of the manage area 5-aza-CdR within GBZ 1-2010 “Hygienic Criteria for your Kind of Professional Enterprises”, and possesses reference point significance for sound management executive.Intake associated with corrosif elements can easily significantly melt away top of the gastrointestinal tract leading to hemorrhaging or even perforation, and may even be life-threatening. A smaller amount generally, damage to the actual trachea as well as bronchi will be included. With this cardstock, a case of harsh gastrointestinal tract injuries and also lungs damage following mouth government involving pipeline dredging agent (the principle components are hydroxide, sea carbonate, sea salt hypochlorite, and so on.) has been reviewed. Soon after productive relief treatment, the person passed away of massive hemoptysis. It’s advocated in which serious complications local immunity will occur soon after ingestion regarding corrosive substances. Timely analysis and sensible medical supervision should increase the amount of recognition along with treating this kind of diseases.Target To create a inductively paired plasma mass spectrometry method for the actual determination of track cobalt along with tungsten in man pee. Techniques Your creators utilised 1% nitric chemical p answer while diluent in October-December 2021, the actual sample dilution aspect and internal common aspect were improved through individual factor rotator test, as well as the among the working necessities along with the normal curve had been in contrast. Final results The method employs doing work contour to ascertain cobalt and also tungsten within pee, your linear range of this method has been 2.0~10.0 μg/L, your connection coefficient had been 0.999 9, the actual discovery limits correspondingly have been 2.005 μg/L (cobalt) as well as Zero.09 μg/L (tungsten), the actual recoveries involving nasal histopathology biological materials respectively were 87.0%~100.2% (cobalt) as well as 89.4%~104.8% (tungsten), the family member regular diversions correspondingly were Zero.4%~4.4% (cobalt) as well as 2.
