Post-Discharge symptoms and analysis for COVID-19 patients /

By Shahjehan, Ayesha . . 65p. , Coronavirus was initially recognized as human COVID by researchers in 1965. Different strains of coronavirus appeared in the following years MERS, SARS-1. Thousands of cases were reported in individuals that to led many casualties, in 2019. New strains of coronavirus emerged, known as covid-19that started to spread from Wuhan, China. It was labeled a worldwide epidemic by the World Health Organization (WHO) in March 2020, the first since 2009. Patients with covid-19 experienced gentle to extreme indications like fever, cough, weariness, shortness of breath, migraine, loose bowels, nausea, and vomiting. As SARS cov-2 is a novel infection, initially the infected patients were treated in a single room along with the utilization of antiviral medication, including oseltamivir, ribavirin, and ganciclovir, lopinavir, and ritonavir to decrease the viral burden. Indications during the contamination may not resolve unexpectedly grumble about persistent side effects, even a long time after the disease. The research is based on observing the symptoms of COVID and postCOVID in patients who perform PCR tests at a hospital. Sample of 26 males and 34 females. Services were taken and their symptoms were noted during and after the quarantine. During the assessment of the covid-19 pandemic, it was seen that overall unexpected issues have gotten even after the onset of intensive covid-19. The prolonged aftereffect stays unexplained. The point of this examination is to represent the persistent symptoms in patients who were released from the health center and to explore the related element of danger. The impact of the study is fundamental in investigating the components and potential persistent post-COVID disorder. It presents a system of procedures for prognosis and handling of patients with suspected or affirmed persevering post-COVID conditions. 30cm.

Data Acquisition & Experimental Analysis Of Power Harvesting From Suspension System /

By Hassan, Ahmad Sabur . . 66p. , Energy crisis and environmental problems such as oil shortage and atmospheric pollution have brought challenges for new development of an energy saving, efficient and environment friendly power transmission system in vehicles. This research is focused on how to use the vibrational energy of the suspension system to generate power that would otherwise go as waste. It is demonstrated that the potential energy of driving vibration is sufficient to be utilized as a sustainable energy. The vibrations experienced by the shock absorber of the vehicle when passed through some irregularities on the road are converted into useful energy by using a regenerative linear or rotary mechanism. As shock absorber effect formed, spring is compressed, and linear movement of rack is converted in rotary motion due to pinion moves as the rack is meshed with pinion. And the pinion is mounted on the shaft of the generator which then produce the power. It is then used to calculate the practical power generated from the regenerative shock absorber by taking the real vibrations amplitude data from the road. The vibrations amplitude data is acquired from the road by driving motorcycle on different road conditions with the setup installed in it to calculate and store the vibrations amplitude data. Later, the same data is applied to the testing rig by using pneumatic and Arduino to find out the voltage generated. The power that is practically generated by testing the mechanism on the rig is around 9.5 watts. The harvestable power from the suspension depends on the vehicle speed, road roughness and stiffness of the tire. This regenerated energy is used to charge the battery. 30cm.

Simulation of Structural Integrity of Rubber Brick Wall for Constructional Purposes /

By Masood, M Faizan Iqbal . . 172p. , An earthquake is a natural phenomenon that causes extreme destruction and death. Earthquakes are caused by sudden releases of energy from the earth's interior that cause the earth's crust to shake. A tectonic plate slips past another during this event. A natural disaster such as an earthquake may be rarer than other types, but it can create more devastation and death than any other natural hazard, making it one of the most destructive on the planet. In Newbury, UK, the International Serological Centre (ISC) and the World Data Centre A in Boulder, Colorado, USA, hold comprehensive lists of seismic events. As part of the efforts to improve earthquake predictability, much research has also been conducted on earthquakeprone areas worldwide. To counteract this destruction, humankind has been evolving and dealing with different methods to reduce the number of lives lost. The objective was to simulate on Abaqus a 4x4 wall of bricks made from polyurethane joined by epoxy to test on what magnitude does wall break. The wall was tested and almost sustained 7.1 magnitude. There were cracks in the wall but the bricks did not break instead the bonding agent gave up and the wall fractured. 30cm.

Study the effect of shallow cryogenic treatment on mechanical and microstructural properties of 30CrMnSiA steel heat treated in vacuum furnace and Box Type conventional air furnace /

By Aslam, Muhammad Danyal . . 50p. , Heat treatment plays a major role in improving the material properties. With the addition of cryogenic treatment these properties can be further improved. In this paper heat treatment is carried out on low carbon low alloy structural steel in two different types of furnaces conventional box type air furnace and vacuum furnace along with shallow cryogenic treatment with the purpose to investigate the outcome of shallow cryogenic treatment on the material properties and to find out which type of furnace is more suitable with shallow cryogenic treatment. For this purpose, structural steel 30CrMnSiA was selected, and heat treatment was carried out in conventional box type air furnace (900°C × 40mins) and vacuum furnaces (900°C × 70mins), shallow cryogenic treatment (-75°C × 125mins) was carried out after the quenching and before tempering. For the physical properties of the material, hardness (HRC) was investigated using Brinell hardness tester HBD-62-5AP. Tensile samples were prepared as per ASTM E8/E8M and investigated using 100kN WAW-100B Electro-Hydraulic Servo Computer Control Universal Testing Machine. Impact toughness was measured by using electronic pendulum impact testing machine CBD-300 and specimens were prepared using ASTM standard E23-12c. Microstructural analysis for grain structure was carried out using Olympus DSX1000 optical microscope. 30cm.
