Design and Simulation of Electricity Theft Detection in Radial Distribution System

Theft of electricity is a significant problem faced by both developed as well as developing countries. It affects both the power as well as economic situation. It also at times is the root cause of blackouts. This paper proposes a method based on the forward–backward load flow and artificial neural networks to detect electricity theft in a radial distribution network. Simulations have been performed in MATLAB Simulink and the results have been presented

Review on Design and Simulation of Electricity Theft Detection and Protection System with their techno-economic Study

Theft of electricity is a major problem faced by both developed as well as developing countries. It affects both the power as well as economic situation. It also at times is the root cause of blackouts. The objective of this paper is to design and simulate a system that can detect, which in turn, will help in protection from electricity theft

Quantitative Analysis of Total Phenolic Content in Avocado (Persia Americana) Seeds in Eastern Province of Kenya

Phytochemical rich plants have played a significant role in diet based therapies to prevent and cure various ailments. The avocado (Persia Americana Mill,) fruits are much sought after for their high nutritional and sensory value. Avocado (Persia Americana) seeds were analysed for total phenolic content. This phenolic component is responsible for antioxidant activity. The amount of phenols was analysed using Folin-Ciocalteu method. The maximum phenolic content was found in the Fuerte seed extract (18.55 ± 2.8 mg/g) prepared at 50ºC. The phenolic content decreased by 10.3% at an extraction temperature of 50 °C to 70 °C and 32.1% at an extraction temperature of 50 °C to 100 °C for a duration of 30 minutes.

Evaluation of Practices and Self- Reported Toxicity Symptoms of Pesticides Handlers: a Survey of Kisumu County, Kenya

Pesticides use in modern agriculture has significantly increased productivity and quality of yield but has also brought negative effects on human health and the environment. Exposures to these chemicals occur through inhalation of vapour, ingestion/oral and dermal/contact. Their effects to human differ depending on the degree and duration of exposure. This study was conducted to evaluate pesticides handlers’ practices and self-reported toxicity symptoms among 80 stockists and 384 farmers. Results indicate that the majority 378 (82%) handlers changed clothing before and after pesticide exposure, 67 (14%) did it occasionally while 19 (4%) never changed their clothes. There was significant association between changing of clothing before and after pesticides exposure and the level of education (χ2 = 14.682; p < 0.01) and position at work (χ2 = 9.168; p < 0.01) and hours of working (χ2 = 10.311; p < 0.03). A total 409 (88%) handlers always had a place to wash hands next to where they store or handle pesticides. There was significant association between participants’ age and availability of washing area (χ2 = 37.325; p < 0.00). Skin itching, coughing, sore throat/ throat irritation were significantly associated with skin and respiratory diseases respectively (RR > 1). Skin diseases resulting from itching and respiratory diseases as a result of coughing and throat irritation can be reduced by 63%, 57% and 79% if exposure to pesticides is reduced by use of appropriate PPEs. Handlers should be trained on effective PPE use and their provision by employers made mandatory. In addition, training on alternative pest control methods such as Integrated Pest Management should be promoted to minimize pesticide use and eventually minimize exposure to pesticides. &nbsp

Isolation and in vitro antiplasmodial activities of alkaloids from Teclea trichocarpa: in vivo antimalarial activity and X-ray crystal structure of normelicopicine.

Seven alkaloids have been isolated from Teclea trichocarpa including four, normelicopicine (1), arborinine (2), skimmianine (6), and dictamnine (7), that are reported for the first time in addition to the previously reported alkaloids melicopicine (3), tecleanthine (4), and 6-methoxytecleanthine (5). The structure of 1 was confirmed by single-crystal X-ray crystallography. Two alkaloids, 1 and 2, displayed limited in vitro activities against Plasmodium falciparum strains HB3 and K1, but there appeared to be little cross-resistance with chloroquine. Alkaloid 1 was found to have some activity against P. berghei in mice (32% suppression of parasitaemia at a dose of 25 mg x kg(-1) x day(-1)), but unlike chloroquine it did not inhibit beta-haematin formation in a cell-free system; 1 was found to have low in vitro cytotoxicity to KB cells (IC50 > 328 microM)
