Design, Construction and Performance Test of an Automatic Fire Fighting System

Securing the modern lifestyle and embedding with the amenity and composure requires intelligent safety systems, that will be cognizant enough to sense and act on the anomaly of ambiance. Fire, undoubtedly, holds the most life-threatening risk when dispersing in an uncontrolled manner. This work represents the design and test of an intelligent fire control system for securing building or home, also fire control linkage system design, at the same time, it describes the following: the idea of the system designing, the system components, selecting equipment, the linkage of sensor and water extinguishing. This system uses different types of sensors and micro controlling devices that use the reservoir tank, pump, and piping system to deliver water and alarm systems to alert people. The result was taken at different temperatures, smoke levels, and flame existence levels. This will inspire the designing of intelligent systems with little investments and humanoid firefighters capable of extinguishing large fires.

ABSTRACT The sterilization chamber is designed to sterilize the body using a filler formulation that is not harmful to the skin surface. Formulation, namely the composition of filler fluids (type, dose and amount) using substances that are safe for the body accordingly, certainly provides benefits. The use of the sterilization booth uses the correct and safe filling fluid. The sterilization chamber uses a mist nozzle sprayer (with the appropriate discharge) to spray the filling liquid so that the user is safe. This sterilization booth is named "White Box". This "White Box" research aims to design (functional and structural) and test (function test and performance test) on a system and mechanism for condensing the condensation of a humidifier that can fill the sterilization room optimally. The design method of the "White Box" sterilization booth uses a qualitative method with the following phases: (1) The preparation stage, namely the functional design and the structural design of the "White Box"; (2) The implementation stage is analyzing the use of tools and materials and making sterilization booths; (3) Post-implementation stage, namely testing the sterilization chamber, including the function test and performance test of the sterilization chamber. The design activity of the "White Box" sterilization booth was carried out by testing various variations of the prototype, including variations in the dimensions of the distribution pipe, the shape of the distribution pipe, and variations of the piping system. The validation process includes: (1) The diameter of the pipe against humidifier dew bursts; (2) The shape of the piping against humidifier dew spray; and (3) the length of the pipe passage to the humidifier dew spray.

Scenario Testing

The rapid spread and evolution of various strains of SARS-CoV-2, the virus responsible for COVID-19, continues to challenge the disease controlling measures globally. Alarming concern is, the number of second wave infections surpassed the first wave and the onset of severe symptoms manifesting rapidly. In this scenario, testing of maximum population in less time and minimum cost with existing diagnostic amenities is the only possible way to control the spread of the virus. The previously described RNA extraction-free methods using dry swab have been shown to be advantageous in these critical times by different studies. In this work, we show the temporal stability and performance of the dry swab viral detection method at two different temperatures. Contrived dry swabs holding serially diluted SARS-CoV-2 strains A2a and A3i at 25° (room temperature; RT) and 4° were subjected to direct RT-PCR and compared with standard VTM-RNA based method. The results clearly indicate that dry swab method of RNA detection is as efficient as VTM-RNA-based method in both strains, when checked for up to 72 hours. The lesser CT values of dry swab samples in comparison to that of the VTM-RNA samples suggest better sensitivity of the method within 48 hours of time. The results collectively suggest that dry swab samples are stable at RT for 24 hours and the detection of SARS-CoV-2 RNA by RT-PCR do not show variance from VTM-RNA. This extraction free, direct RT-PCR method holds phenomenal standing in the present life-threatening circumstances due to SARS-CoV-2.

Healthcare workers may be exposed to various aerosols formed during patient care and treatment. Transmission of bacterial or viral infections to the healthcare staff by this route can be life threatening. Worldwide, many national and international occupational health and safety organizations consider medical masks and respirators as an important element of protecting healthcare workers against exposure to hazardous aerosol particles. With the recent COVID-19 pandemic, the features and standards of masks that should be used in different settings have become an important topic of discussion. The masks produced in compliance with standards are widely used against harmful aerosols and protect the user when properly installed. These medical and respiratory masks are among the important personal protection equipment widely used in healthcare to prevent transmission of bacterial and viral infections as well as COVID-19. Here, it was aimed to review the structural features and performance test standards of the masks used during medical procedures.

BACKGROUND: Few studies have investigated the variations in body composition and performance in Japanese collegiate American-football players. OBJECTIVE: To clarify what characterizes competitors at the highest levels – in the top division or on the starting lineup – we compared players’ body compositions and performance test results. METHODS: This study included 172 players. Each player’s body composition and performance (one-repetition maximum bench press, one-repetition maximum back squat, and vertical jump height) were measured; power was estimated from vertical jump height and body weight. Players were compared according to status (starter vs. non-starter), position (skill vs. linemen), and division (1 vs. 2). Regression analysis was performed to determine characteristics for being a starter. RESULTS: Players in higher divisions and who were starters were stronger and had more power, greater body size, and better performance test results. Players in skill positions were relatively stronger than those in linemen positions. Vertical jump height was a significant predictor of being a starter in Division 1. CONCLUSION: Power and vertical jump may be a deciding factor for playing as a starter or in a higher division.
