An electricity market is a trading platform provided by the actors in the electricity sector to sell and buy electricity while maintaining the stability of the transmission network and minimizing energy *** management of electrical energy for rational use consists of all the operations that the consumers can carry out in order to minimize their electricity bill,while the producers optimize their benefits and the transmission *** reduction of active and reactive power consumption and the smoothing of daily and yearly load profiles are the main objectives in this *** developed countries already have properly functioning electricity markets,but developing countries are still in their infancy of deregulated electricity *** major tools used in smoothing the load profiles include decentralized generation,energy storage and demand response.A load power smoothing control strategy is proposed to smooth the load power fluctuations of the distribution *** required power change is determined by evaluating the power fluctuation rate of the load,and then the required power change is allocated to some generators or to some stored ***,the consumers are made to curtail their power *** ideas proposed in this work provide important opportunities for energy policy makers and *** ideas would only be feasible if there exists real-time communication among the actors in the electricity *** results indicate that as much as 1100 Megawatt-hours of energy can be stored for smoothing the load profile,when applied to the Southern Interconnected Grid of the Cameroon power system;and that Time of Use(TOU)pricing could be used instead of rotating blackouts in case of energy shortage.

Collaborative Efforts and Strategies for Cholera Outbreak Control in Garissa County, Kenya: Implementation of Water Quality Monitoring Interventions

Journal of Water Resource and Protection 2024年第2期16卷 123-139页

Noor Joel Mutyandia Muli Alan Mwika Julius Wekesa Ahmed Fidhow Diba Dulacha Landry Kabego Ishata Nannie Conteh Andre Arsene Bita Fouda Sonia Chene Aden H.

A multi-faceted Case Area Targeted Intervention (CATI) approach emphasizing the integration of Water, Sanitation and Hygiene (WASH) interventions and Oral Cholera Vaccine (OCV) campaign was employed to respond to the outbreak of cholera in Garissa County. Drinking water sources in areas heavily impacted by cholera were systematically mapped and tested for microbiological quality. The quality assessment was carried out in April 2023 during an ongoing cholera outbreak in the county. A total of 109 samples were collected and tested for thermotolerant coliforms and other in situ parameters. The finding revealed that more than 87% of the samples did not meet the World Health Organization (WHO) standard for thermotolerant coliforms;and 30% had turbidity values above the recommended threshold values. None of the 109 samples had any traceable residual chlorine. Following these findings, the county government implemented the targeted interventions which resulted in a positive impact in the fight against cholera. The WHO supported key interventions which included capacity building in water quality monitoring and prepositioning of critical WASH commodities to the cholera affected areas.

Full term secondary abdominal pregnancy in a Jehovah’s witness: A case report

We describe a rare case of full term abdominal pregnancy in a Jehovah’s witness patient;she underwent laparotomy successfully without blood transfusion. Despite their belief regarding transfusion, Jehovah’s witnesses may not necessarily have a higher morbidity or mortality rate following a complex obstetric surgery as seen in the present case.

Contagious bovine pleuropneumonia is a disease caused by Mycoplasma mycoides subspecie mycoides, a transboundary animal disease causing serious devastation to cattle producers in Africa. The study was designed to identify and characterize the pathogenic member of mycoplasma cluster the Mycoplasma mycoides subspecie mycoides (Mmm) isolated from cattle infected with the disease. Three hundred (300) samples of nasal swabs and pleural fluid from cattle showing signs of CBPP were analyzed using culture and biochemical identification techniques and polymerase chain reaction (PCR) using specific primers to determine the prevalence of contagious bovine pleuropneumonia in Nasarawa State, Nigeria. Isolation recorded a prevalence of 4% and PCR recorded a prevalence of 67.7%. Isolates subjected to PCR analysis produced an amplicon size of 548 bp and 1.1 k bp respectively for the Mycoplasma mycoides cluster and Mycoplasma mycoides subspecie mycoides. Sequencing of the 16 S rRNA gene blast search revealed 96% to 99% sequence homology of Mycoplasma mycoides subspecie mycoides compared with 14 available sequences in the gen bank at NCBI. Based on this investigation mass vaccination of cattle is recommended, isolation and PCR techniques could be used as diagnostic tools for CBPP disease in three agro ecological zones of Nasarawa state, Nigeria.
