Fever is a common symptom for various infectious diseases that are reporting nowadays in a massive amount like COVID-19, Ebola and so on that will directly affect our whole human cells and are showing a lot of chromosomal aberrations too. Since there was not a unique way are to predict how these diseases will affect our body both physically and mentally, since they can create some aftereffects in future too, there should be a suitable system which will efficiently detect these type of pandemic. In all these situations thermal screening had emerged as a remedial method for the detection of temperature variations. Among this Infrared thermography had been used as the best and effective method for fever screening. This survey presents some of the important papers which discussed how Infrared thermography can be effectively utilized for the detection of these epidemics by analyzing the temperature variations done in fever screening. Infrared thermography (IRT) is a method which uses an imaging scheme that gives you an image which is a thermal diagram that shows the temperature variations of various intensities. IRT uses the basic working principle from Stefan-Boltzmann Law, where the relationship between the temperature and the emissive power is established and the camera which is the infrared camera will capture this infrared energy and is converted into corresponding electronic signals. This paper gives a brief idea about various techniques used for fever screening which can be used to detect various diseases.
Lightweight concrete (LWC) is used in the construction of partition and panel walls in framed structures because it reduces the dead load acting on the structure. Rubberized lightweight aggregate concrete is made by using waste rubber tyre chips as a partial replacement of coarse aggregate which increases the ductility, and toughness and minimizes the impact effect of concrete. The presence of rubber content decreases the compressive strength and bond strength, which affects the durability of concrete. Nowadays, nanomaterials' application has received much attention to enhance concrete properties. Due to the nano-filler effect and the pozzolanic reaction, the microstructure becomes more homogeneous and less porous, especially at the interfacial transition zone (ITZ), which leads to reduced permeability. Among the nano-materials, nano-silica has gained particular attention compared to conventional mineral addition due to its better performance in concrete. Incorporating a small number of nanoparticles in concrete can modify the nano-structure of cementitious materials, thus producing high strength and durability. This study is to investigate the durability properties of rubberized LWC containing nano-silica at dosages of 1%, 3%, and 5% by replacement of cement, respectively. Durability under a marine environment is to be analysed based on compressive strength, bond strength, and resistance to the penetration of chloride ions for 28 and 56 days.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
