Abstract: The investigation of extreme events is extremely relevant for a range of disciplines in mathematical, natural, and social sciences and engineering. Understanding the large fluctuations of the system of interest is of great importance from a theoretical point of view, but also when it comes to assessing the risk associated with low probability and high impact events. In many cases, in order to gauge preparedness and resilience properly, one would like to be able to quantify the return times for events of different intensity and take suitable measures for preventing the expected impacts. Prominent examples are weather and climate extremes, which can have a huge impact on human society and natural ecosystems. The present uncertainty in the future projections of extremes makes their study even more urgent and crucial.

Abstract: Turkeys in good physical condition may suddenly die without preceding clinical signs of illness. A condition known as “sudden death with perirenal hemorrhage” needs to be considered as a possible cause. Diagnosis of this condition is based on characteristic internal lesions in the birds, this condition occurs mainly in meat-type or breeder turkeys.

Abstract: Coronavirus disease 2019 (COVID-19) is an infectious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The virus is mainly spread during close contact and via respiratory droplets that are produced when a person talks, coughs, or sneezes. Respiratory droplets may be produced during breathing, however, current research indicates that the virus is not considered airborne. People may also contract COVID-19 by touching a contaminated surface (Fomite) and then inadvertently transfer the pathogen to a mucous membrane (such as the eyes, nose, or mouth). It is most contagious when people are symptomatic, although spread may be possible before symptoms appear. The virus can live on surfaces up to 72 hours. Time from exposure to onset of symptoms is generally between two and fourteen days, with an average of five days. The standard method of diagnosis is by reverse transcription polymerase chain reaction (rRT-PCR) from a nasopharyngeal swab. The infection can also be diagnosed from a combination of symptoms, risk factors and a chest CT scan showing features of pneumonia. This article introduces recent research reports as references in the related studies.

Abstract: Vehicle windshield wiper system increases the driving safety by contributing a clear shot viewing to the driver. In this paper, modelling, designing and simulation of a vehicle windshield wiper system with robust control theory is done successfully. H  loop shaping and robust pole placement controllers are used to improve the wiping speed by tracking a reference speed signals. The reference speed signals used in this paper are step and sine wave signals. Comparison of the H  loop shaping and robust pole placement controllers based on the two reference signals is done and convincing results have been obtained. Finally the comparative results prove the effectiveness of the proposed H  Loop Shaping controller to improve the wiping mechanism for the given two reference signals.

Abstract: In this paper, the design of a low cost portable ventilator with performance analysis have been done to solve the scarcity of respiratory ventilators for COVID-19 patients. The materials used to build the system are: DC motor, rotating disc and pneumatic piston. The system input is the patient heart beat and the output is volume of air to the patient lung with adjusted breathing rate. This ventilator adjusts the breathing rate to the patient depending on his heart beat rate. The performance analysis of this system have been done using Proportional Integral Derivative (PID) and Full State Feedback H2 controllers. Comparison of the system with the proposed controllers have been done using a step change and a random change of the patient heart beat and a promising result have been analyzed successfully.

Abstract: Benzene and Toluene species concentrations relationship and interaction were determined in the air basin of Pipelines and Products Marketing Company Mosimi Depot, Sagamu, Nigeria. This study is to evaluate the status level of these air pollutants emitted from Mosimi Petroleum depot industrial area using active sampling and gas chromatography fitted with flame ionization detector; Model: HP 6890. Air samples were collected over granular activated charcoal with 10-18 mesh using a low volume air sampler. The Model: Negretti 1000 ^tm sampler was placed at human breathing height of 1.5m for a sampling period of eight hours at different sampling location. Desorption process was carried out on the used activated charcoal using solvent extraction method with carbondisulphide as the solvent. The extracted solutions were subjected to gas chromatography fitted with flame ionization analysis. The gas chromatography was powered with chem-station REV A09.01 [1206] software to determine the concentration of each of the benzene and toluene species present. The concentrations of benzene ranged between 0.0104 and 0.0711 mg/m³ while that of toluene ranged between 0.0019 and 0.0998 mg/m³ within Pipelines and Products Marketing Company in Mosimi depot and host environment. Toluene to benzene ratio ranged between 1.32 and 1.77 which indicate both species are from multiple similar sources.

Abstract: Bipolar disorders (BPD) are major, life‐long psychiatric illnesses found in 2–5% of the population. It is characterised by the occurrence of one or more manic or hypomanic episodes, usually alternating with depressive episodes.  While the causes of bipolar disorder are not clearly understood, both genetic and environmental factors are thought to play a role. Genetic factors account for about 70–90% of the risk of developing bipolar disorder. Environmental risk factors include a history of childhood abuse and long-term stress. Mood stabilizers-lithium and certain anticonvulsants such as valproate and carbamazepine—are the mainstay of long-term relapse prevention. Antipsychotics are given during acute manic episodes as well as in cases where mood stabilizers are poorly tolerated or ineffective or where compliance is poor. There is some evidence that psychotherapy improves the course of this disorder. The use of antidepressants in depressive episodes is controversial. Electroconvulsive therapy (ECT) is effective in acute manic and depressed episodes, especially with psychosis or catatonia.

Abstract: This is a challenging time for global public health and particularly for the fragile health of populations in developing countries. However, the increasing resources for international health aid and growing demand to improve health systems offer an opportunity to foster health equity in countries most in need. Many of the solutions to health problems of the poor exist, but are not applied, leading to what is called the “know-do” gap: the gap between what is known and what is done in practice. The mission of WHO Knowledge Management (KM) is to help bridge the “know-do gap” in global health by fostering an environment that encourages the creation, sharing, and effective application of knowledge to improve health. This in turn is seriously aggravated by poverty, the continuing HIV/AIDS pandemic and other problems. In the face of these and numerous other complexities, governments are struggling to build and sustain their health systems.

Abstract: Cancer is the general name for a group of more than 100 diseases. Although there are many kinds of cancer, all cancers start because abnormal cells grow out of control. Untreated cancers can cause serious illness and death. The body is made up of trillions of living cells. Normal body cells grow, divide, and die in an orderly fashion. During the early years of a person’s life, normal cells divide faster to allow the person to grow. After the person becomes an adult, most cells divide only to replace worn-out or dying cells or to repair injuries. This article introduces recent research reports as references in the related studies.
