Prevention and Safety Training to Improve Community Health
Abstract:
Public health problems are caused by the emergence of environmental pollution and infectious diseases, which have caused concern around the world. The public health threat affects the relationship between people. Population growth and associated pressures increase difficulties associated with effective means of maintaining public health. The diseases transmitted from human and livestock communication, water pollution, air pollution, and environmental pollutants urge us to find new solutions to address these problems. Understanding the environmental and environmental health is a prerequisite for protecting public health. In Iran, like other countries in the world, the issue of environmental protection and its compliance with the first program of economic, social and cultural development of the Islamic...
Safety of BBIBP-CorV (Sinopharm) COVID-19 Vaccination in People With Multiple Sclerosis: A Report From Iran
Abstract:
Vaccination against SARS CoV-2 started on March 2020 in Iran and people with multiple sclerosis (pwMS) have a priority to be vaccinated in line of other high-risk population. Up to now, BBIBP-CorV (Sinopharm) is the main vaccine which have been used in Iranian population, and in high risk population such as pwMS. In this survey, the safety and possible side effects of this vaccine after the first or/and second doses in 520 pwMS have been assessed from July to August 2021. MS Patients who have received one or two doses of Sinopharm vaccine were evaluated. Around 44% of pwMS who received Sinopharm reported few minor side effects, whereas its side effect have been reported in 60% of patients who receiv...
Screening Sorghum Genotypes for Striga Resistance
Abstract:
In Niger, sorghum (Sorghum bicolor) is one of the most important staple crop for food and money. Despite the importance of the crop and its easiest adaptative capacity to dry, the crop is confronted to striga (Striga hermonthica), a plant parasite, which drastically hinder the productivity and causing yield loss between 20% to 80%. The best and easiest way to control and improve sorghum productivity is through the development of novel Striga resistance sorghum genotypes. The purpose of this study was to assess 20 sorghum genotypes from diverse country for striga resistance and grain yield capacity. Varieties with high yield average, medium size and resistance to Striga were found.
The trajectory of immunoglobulins immune response against the different amounts of xenobiotics matches the trajectory of biological changes associated with ageing: A systematic review
Abstract:
Ageing is a life process in which progressive molecular, cellular, physiological and anatomical changes manifesting in humans and animals including other organisms lead to the decline of biological functions. Immunoglobulins (Igs) are glycoprotein molecules produced by white blood cells mainly B lymphocytes following signal transduction as a result of their interaction with pathogenic microbes or poisonous substances introduced into the body systems. They elicit responses against the side effects of pathogens and poisons in which their response efficiency usually declines as we are ageing. Thus, the similarities between Igs’ immune response against the different amounts of xenobiotics and the biological changes associated with ageing have been systematically assessed using the reports of diff...
Clustering objects for spatial data mining: a comparative study
Abstract:
Spatial data mining (SDM) is searching important relationships and characteristics that can clearly exist in spatial databases. This content aims to compare object clustering algorithms for spatial data mining, before identifying the most efficient algorithm. To this end, this paper compare k-means, Partionning Around Medoids (PAM) and Clustering Large Applications based on RANdomized Search (CLARANS) algorithms based on computing time. Experimental results indicate that, CLARANS is very efficient and effective.
Willingness to take COVID-19 Vaccination among People Living with HIV/AIDS on Anti-Retroviral Therapy and Associated Factors in Woldia Comprehensive Specialized Hospital, Woldia, Ethiopia
Abstract:
HIV causes immunosuppression, which reduces the body's immunity to diseases like COVID-19 by decreasing CD4 cells. The goal of this study is to determine whether persons living with HIV/AIDS (PLWHA) who are using anti-retroviral therapy (ART) are willing to accept the Coronavirus illness 2019 vaccination and the factors that influence their decision. From February 15 to March 15, 2022, 332 PLWHA on ART participated in this facility-based cross-sectional study. The correlation of outcome variables with predictors was investigated using binary and multivariable logistic regression. Of the 332 study participants, 110 (33.1 %) and 118 (35.5 %) had poor knowledge and a negative attitude towa...
Production of dried tomato powder with a high concentration of functional components and nutrients
Abstract:
The use of conventional drying methods for dehydrating vegetables and fruits with high sugar, amino acid, and moisture content is not feasible. Under extreme conditions, drying reduces the amount of functional ingredients present in these vegetables and fruits. Recently, there has been an increasing demand for powdered tomatoes because of their nutritional and functional components. This study aimed to evaluate tomato drying under normal pressure and low-temperature conditions, to efficiently reduce water content without compromising on product quality. A convection dryer, most widely used in food factories, was used in this study. This equipment uses a low temperature zone not normally used for drying, and processes the raw material to increase the drying area for rapid drying. The proposed method was validated by comparing the moisture and functional component contents, and the antioxidant activity of the dried pro...
A review of ultrasound for the diagnosis of acute appendicitis in adults
Abstract:
Acute appendicitis is one of the most common surgical emergencies globally, with a lifetime incidence of 8.6% in men and 6.7% in women. While acute appendicitis should be managed promptly to reduce the morbidity associated with perforated appendicitis, morbidity from negative appendicectomy is similar to morbidity from uncomplicated appendicitis. Computer tomography is widely used to aid in the diagnosis of acute appendicitis, however, is costly, often has a slow turn around time, and is associated with exposure to ionising radiation. In contrast, ultrasound is cheap, widely available, requires minimal patient preparation, and does not require exposure to ionising radiation. Ultrasonography is becoming increasingly used for adult patients in emergency settings. The literature has estimated the sensitivity of ultrasound for acute appendicitis in adult patients as between 39-96.4%. The sensitivity and specificity of ultrasound ...
The Design and Demonstrative Analysis of the Gas Turbine Operation’s Simulator
Abstract:
The Gas Turbine operation was investigated with a view to evolving a system designed to provide a realistic imitation of the controls and operation of a Gas Turbine, used for training purposes. Operator Training Simulator has been widely adopted by many industries being a computer simulation which attempts to model a real-life plant so that it can be studied. A well trained and skilled operator is key in increasing power plant safety and productivity. Therefore, enabling quality training for operators is becoming more important as they need to handle increased load of information and duties whereas the lack of training is a major reason for inadequate performance. By changing variables in the simulator, predictions are made about the behaviour of the engine. It is a tool to virtually investigate the behaviour of the system while in operation. This work becomes indispensable because it is prohibitively expensive or simply too dangerous to allow trainees use th...
Specified model of the work environment in a public university in central Mexico
Abstract:
The work environment, in its most general conception, alludes to biased expectations of risks and benefits around a function and in relation to the performance of a working group, but in its factorial structure, dimensions have been found that explain a moderate percentage of the variance of the construct. In this sense, the objective of this paper is to specify a model for the study of the work climate, considering the institutionalism and human capital of a public university. An exploratory study was carried out with an intentional sample of 125 administrative personnel. From a structural model it was found that the relationship climate factor explained the highest percentage of the variance (21%) and it was the reflective dimension of the construct (0.524). The inclusion of the task climate is recommended due to its link with the leadership and the collaborative climate.
