Development of a Virtual Assistant Maintenance System for Some Computer System Issues

Virtual assistants constitute a rich history dating back to the early 1960s; however, they did not gain popularity until the 21st century. The manual maintenance of computer systems can be time-consuming, complex, and error-prone, leading to system downtime and decreased productivity. This study developed a Virtual Assistant system for some Computer System Maintenance issues. The analysis of existing applications and the design was done using Customtkinter. The design was implemented using Python. The Applications were tested for all four major functionalities (Network Test, Sort Files, Clear Bin, and Find) of the developed system. The Evaluation metrics used were CPU Utilisation, Memory Utilisation, and Response Time. The result of the evaluation shows that the Application's CPU usage had an average of 40%, memory space takes about 22.7MB, and the system takes around 1 minute to respond to users' requests. The application was deployed to the Microsoft Store. System maintenance through VAMS will pave the way for a new era of efficiency, productivity, and user satisfaction, propelling organisations toward success in the digital era

Microbial production of 2,3-butanediol from rice husk using anaerobic Clostridium species

Interest in the area of biomass based-product production is increasing all over the world due to the environmental challenges posed by fossil fuel and fear of its extinction. Production of biofuel and other compounds especially from agricultural waste can reduce these environmental problems because of its sustainability and environmentally friendliness. One of the major petrochemical product widely used in many industries is 2,3-butanediol and was found to be produced from agricultural wastes by microorganisms. Therefore, Microbial production of 2,3-butanediol from rice husk using Clostridium species was investigated in this research. Structural composition of the rice husk was determined before and after pretreatment. Hemicellulose and lignin content of rice husk was determined after extraction while cellulose was determined as the difference from the extractives, hemicelluloses and lignin. Dilute (2%) NaOH was used for the pretreatment of rice husk. Hydrolysis was carried out using Aspergillus niger and reducing sugar released was determined using standard method with UV-VIS spectrophotometer. Clostridium species was isolated from sugarcane bagasse, identified using basic morphological and molecular biology techniques. The fermentation of rice husk was performed using the Clostridium species. Fermentation by-product was determined using Gas Chromatography Mass-spectrometry. Cellulose content increased from 32% before pretreatment to 53.3% after pretreatment, lignin increased from 8.4% before pretreatment to 30.7% after pretreatmemt and hemicellulose decreased from 30% before pretreatment to 8% after pretreatment. A total of 1.05 g/l of reducing sugar was released after enzymatic hydrolysis of the rice husk with Aspergillus niger. Alcohol 2,3-butanediol (0.6%) and Furfuryl alcohol (0.45%) were detected in the by-product of fermentation. Other compounds detected are fatty acids that ranges from C16 to C25 with 9,12-Octadecanoic acid as the major fatty acid. From the results of this work, Rice husk was found to have substantial amount of sugar (cellulose and hemicelluce) that can be converted to valuable product including 2,3-butanediol.

Candida albicans and Napkin Dermatitis: Relationship and Lesion Severity Correlation

Introduction: Napkin Dermatitis (ND) is a common problem in infancy that affects almost every child during the early months and years of their lifetime. It is a skin disease that becomes a challenge for both parents and physicians because of its frequency and difficulty in eliminating all of the causative factors in diapered infants. Usually Napkin dermatitis is self-limiting but when associated with Candida albicans (C. albicans) seems to be moderate to severe.Aim: The aim of the present study was to determine the colonization of C. albicans in children with Napkin dermatitis and to correlate between intensity of C. albicans colonization and the severity of napkin rash.Patients and Methods: This case-controlled study was conducted at Qassim University pediatric outpatient clinics, during the period from August 2014 to July 2015. Sixty patients with diaper dermatitis and 33 healthy controls were enrolled to this study. Sociodemographic and clinical data were obtained from the parents of each participant using questionnaires Paired (stool and skin) samples were collected from all cases and healthy control children. The samples were cultured on differential and selective chromogenic medium for isolation and initial identification of candida species. Identification confirmation of the isolates was determined by the Vitek 2 compact automated system.Results: Diaper dermatitis shows significant outcome to washing diaper area (per day) (P=0.001), History of diarrhea last 7 Days (P˂0.001), skin lab results (+/-) for Candida albicans, (P˂0.001), skin colony count, (P˂0.001), However, there is no correlation to age (P=0.828), gender (P=0.368) and feeding style (P=0.401).Conclusion: The severity score of napkin dermatitis was significantly observed among cases with diaper dermatitis (p-value<0.001) and control children (p-value<0.001) respectively.Keywords: Candida albicans; Napkin dermatitis; Diaper dermatitis; Vitek 2 compact system; Qassim

The role of antibodies in the treatment of SARS-CoV-2 virus infection, and evaluating their contribution to antibody-dependent enhancement of infection

Antibodies play a crucial role in the immune response, in fighting off pathogens as well as helping create strong immunological memory. Antibody-dependent enhancement (ADE) occurs when non-neutralising antibodies recognise and bind to a pathogen, but are unable to prevent infection, and is widely known and is reported as occurring in infection caused by several viruses. This narrative review explores the ADE phenomenon, its occurrence in viral infections and evaluates its role in infection by SARS-CoV-2 virus, which causes coronavirus disease 2019 (COVID-19). As of yet, there is no clear evidence of ADE in SARS-CoV-2, though this area is still subject to further study

Experimental and numerical study on the thermal performance of earthbag-wall units incorporated with phase change materials

The demand for temporary housing for refugees and displaced communities has led to the development of earthbag buildings. While these structures are affordable and sustainable, they often struggle with thermal discomfort in extreme climates. This study aims to examine the integration of phase change materials (PCM) into earthbag walls to improve thermal performance. The research involved incorporating paraffin wax and microencapsulated PCM into scaled-down earthbag walls, with their performance evaluated in a controlled environment. The results were validated against a numerical simulation model developed in EnergyPlus. The study revealed significant thermal improvements with PCM integration. Wall-2, with paraffin wax A31, demonstrated a surface temperature reduction of up to 1.9 °C, while Wall-3, with microencapsulation Inertek26, showed a decrease of 2.4 °C compared to the reference wall. A parametric analysis highlighted the importance of PCM layer thickness. Specifically, Wall-2 with a 6 cm paraffin wax layer achieved a maximum reduction of 4.0 °C compared to the base case. The study identified the transition temperature of PCM as a critical factor in thermal performance, with paraffin wax A31 emerging as the optimal choice. Placing the PCM layer on the interior surface of the wall was more effective than exterior placement. Overall, PCM integration in earthbag walls offers a promising solution to enhance thermal comfort in temporary housing, addressing the critical needs of refugees and displaced communities. This research fills existing gaps in thermal comfort in temporary housing and demonstrates the potential of PCM as an innovative passive design strategy

Functionalisation of inorganic material surfaces with Staphylococcus protein A : a molecular dynamics study

Staphylococcus protein A (SpA) is found in the cell wall of Staphylococcus aureus bacteria. Its ability to bind to the constant Fc regions of antibodies means it is useful for antibody extraction, and further integration with inorganic materials can lead to the development of diagnostics and therapeutics. We have investigated the adsorption of SpA on inorganic surface models such as experimentally relevant negatively charged silica, as well as positively charged and neutral surfaces, by use of fully atomistic molecular dynamics simulations. We have found that SpA, which is itself negatively charged at pH7, is able to adsorb on all our surface models. However, adsorption on charged surfaces is more specific in terms of protein orientation compared to a neutral Au (111) surface, while the protein structure is generally well maintained in all cases. The results indicate that SpA adsorption is optimal on the siloxide-rich silica surface, which is negative at pH7 since this keeps the Fc binding regions free to interact with other species in solution. Due to the dominant role of electrostatics, the results are transferable to other inorganic materials and pave the way for new diagnostic and therapeutic designs where SpA might be used to conjugate antibodies to nanoparticles

Treatment by agricultural by-products of Industrial effluents polluted with heavy metals

Due to the increasing concern about the environmental pollution problems, it is so important to perform a number of methods for removing hazardous heavy metals from industrial liquid wastes. Adsorption technique is the most effective and economical one. In the present study, two agricultural by-products namely; cottonseed and soybean hulls, resulting from the oil industry, have been used in the adsorption of thorium element from a wastewater effluent coming from different industries. The results obtained indicate that maximum removal of thorium from a prepared solution takes place at pH 5 where equilibrium was attained after 100 min; using an adsorbent dose of 3 and 3.5 g/L for cottonseed and soybean hulls, respectively. On the other hand, the obtained mathematical data together with the obtained adsorption kinetic parameters indicate that both of cottonseed and soybean hulls could be useful adsorbents for thorium removal from industrial liquid wastes, especially when the low cost, environmental issues and high availability of these materials are considered
