Introdução: A cefaleia em salvas, uma forma de dor de cabeça caracterizada por episódios agudos e intensos de dor unilateral, frequentemente acompanhada de sintomas autonômicos, tem sido objeto de considerável atenção no campo da neurologia e da genética. Metodologia: Esta revisão sistemática da literatura foi conduzida com o objetivo de explorar as correlações entre a cefaleia em salvas e variáveis ambientais e genéticas, utilizando uma abordagem rigorosa e abrangente para identificar estudos relevantes na literatura científica. A metodologia obedece às diretrizes recomendadas para revisões sistemáticas, priorizando a inclusão de estudos previstos entre 2013 e 2023, com acesso ao texto completo. Resultado: É crucial reconhecer que o padrão genético da cefaleia em salvas não se apresenta de maneira unívoca, revelando uma complexidade multifatorial em sua etiologia. Ainda que fatores genéticos possam conferir uma predisposição, sua expressão clínica parece ser modulada por influências ambientais. Estudos explorando as interações entre genes e ambiente têm se dedicado a compreender como fatores extrínsecos, como expor certos estímulos ambientais, podem modular a atividade genética e desempenhar um papel no desencadeamento de episódios de cefaléia em salvas. Conclusão: A cefaleia em salvas representa uma condição neurológica singular e desafiadora que continua a intrigar profissionais da saúde e pesquisadores. Sua característica distintiva de dor intensa, acompanhada por sintomas autonômicos, contribui para a complexidade do quadro clínico.

Published: January 2024

The multivariate Principal Component Analysis (PCA) was used to assess the variations in the water quality of the "Omi Omo" Stream. This allowed for the identification of temporal and spatial variations in the water quality caused by contamination by analysing the similarities and differences between the sampling points. For three months, four sampling locations along the streamline provided data on the quality of the water. Temperature and other physicochemical parameters were used to analyse the samples. Turbidity, alkalinity, Electrical Conductivity (EC), hardness pH, Total Dissolved Solids (TDS), Dissolved Oxygen (DO), Biological oxygen demand (BOD), heavy metals (Cd, Cu, Pb, Fe, Mn), sulphate, phosphate, nitrate and chloride were also determined. For the months under study, PCA helped identify and extract the factors causing variations in water quality. The important factors influencing the variation in water quality for the three months of study were turbidity, TDS, alkalinity, electrical conductivity, nitrate, calcium, and chloride. The comparison of the stream’s physicochemical parameters with the W.H.O standards shows an acceptable correlation except for the turbidity and the EC which for some period were higher than the acceptable level of the W.H.O standard. The study's findings will assist pertinent authorities in determining how to improve the declining water quality caused by pollution from various human activities.

The ongoing energy crisis and degenerating climate condition demands urgent transformation of the energy system to renewable based from nonrenewable (fossil) based. To meet the growing demand for energy services and simultaneously mitigate the environmental impact of the energy sector, an accurate estimation of the demand for renewable generated electricity is vital to guide the policy makers in planning adequately for the adoption of renewable fuelled electricity generation technology in urban areas. This study evaluated the electricity demand for residential solar photovoltaic (RSPV) technology by potential household adopters of the technology in the metropolitan area of Lagos state, Nigeria. The study adopted quantitative research design with structured questionnaire to solicit information from the respondents. Three hundred and twenty-six (326) responses from the potential adopters were analysed with model for analysis of demand for energy (MADE II) and Pareto tool. The results show that the energy intensity for refrigeration services is 1.06 kWh/hh/day, entertainment services is 0.84 kWh/hh/day, computing services is 0.97 kWh/hh/day, space cooling services is 7.59 kWh/hh/day, ventilation services is 9.05 kWh/hh/day, lighting services is kWh/hh/day, cooking services 2.77 kWh/hh/day, process heating services is 6.43 kWh/hh/day and water pumping is 1.89 kWh/hh/day. The study concluded that the household energy services demand for electricity is 24.43 kWh/hh/day by the potential RSPV technology adopters and the total demand from the solar module panel of 31.59 kWh/hh/day with prospect for improvement on the energy intensity at the same output of energy services. Furtherance to this, the study recommends government intervention with formulation and implementation of dedicated policies on household appliances efficiency standard and also introduce financial schemes to support the replacement of inefficient household appliances with highly efficient ones. Further studies could include other non-common energy services that were not considered in this study. The study could also be conducted in other regions of Nigeria and also investigate the economic feasibility and behavioural acceptability of RSPV technology for effective planning of the national energy system transformation.

Standalone energy generation is revolutionizing electricity production and consumption by offering decentralized and sustainable options, benefiting communities, enhancing resilience, and reducing dependence on traditional power grids. Nevertheless, standalone electricity systems can face overloading issues when demand varies or exceeds capacity, necessitating careful control and adaptable solutions. The scalability of standalone electricity systems is limited by infrastructure, technology, and cost, hindering easy capacity expansion to accommodate higher loads. This paper explores the feasibility of managing load shedding in an office building with a standalone energy source, assessing its impact on optimizing electricity consumption and contributing to operational efficiency, sustainability, and resilience. A hardware prototype has been developed for a programmable interface designed to automatically manage various loads from the distribution board in a controlled manner. This includes controlling lighting, heating, cooling, security devices, and essential office gadgets. The system is implemented and validated through experiments utilizing the Arduino Mega control board. Operators can input load-shedding times flexibly using a 4x4 matrix keypad synchronized with the real-time clock (RTC). The microcontroller then instructs the relay to shed the specified load, displaying the shedding time on the LCD. The results indicate that the programmable interface exhibits a high dynamic response speed, highlighting its effectiveness and flexibility in load-shedding management. Comparing the cost of building the device with the long-term cost of overloading a standalone electricity generator, considering accelerated wear and tear, increased maintenance expenses, reduced operational lifespan, potential premature equipment failure, and overall decreased reliability, underscores the high-cost efficiency of adopting this device in office buildings. Additionally, implementing the system in an office building with an energy consumption of 23 kWh resulted in a discernible annual energy saving of 2.52 kWh by shedding off unnecessary loads at estimated timings.

Presented in this study is an artificial intelligence approach to pitch angle control in wind turbines for the enhancement of the power generation efficiency of wind energy conversion systems. A two-input neural network model was developed and trained using backward propagation technique to adjust the pitch angle of the turbine in response to the speed of turbine generator and the rate of change of the speed. Ten-year real-life data on the wind speeds of a study location was used to validate the approach. It was found that the method performs well in controlling the mechanical power developed by the turbine above the turbine’s rated wind speed, and with fast processing time. 44.44%improvement was achieved in the mechanical power developed by the turbine. The control approach is thus recommended for the effective management of wind energy conversion systems towards enhancing availability and reliability of electric power supply.
