Power system transient stability enhancement with application of SSSC and IPFC facts devices
(2015)The complexity due to massive growth of power systems has to increased demand of electrical energy giving rise to numerous stability challenges. In these situations, Flexible Alternating Current Transmission System (FACTS) ... -
Optimal location of TCSC and its use in congestion management
(2015)Over the last two decades, electricity demand has increased substantially while the expansion of generation and transmission network has been limited due to environmental and/or economic constraints of building new ... -
Transient stability analysis of the kenyan power system with different wind generation technologies.
(2014)Electrical power generation from wind is achieved using a number of generator technologies. The main technologies are the Squirrel Cage Induction Generators (SCIG) and Doubly Fed Induction Generators (DFIGs). In this paper, ... -
Dynamic voltage stability analysis of the kenya power system using decision trees
(2014)Dynamic Voltage stability analysis of any system is studied by considering load changes within the system and how voltage magnitudes at the load buses within the system are affected by the load changes. The analysis can ... -
Dynamic voltage stability analysis of the kenya power system using vcpi stability index and artificial neural networks
(2014)Dynamic voltage stability deals with the voltage levels and how they’re affected by either faults or load changes within the system. Voltage instability has long been suspected in the voltage collapse and islanding of power ... -
Comparison of aggregation of small and large induction motors for power system stability study
(2013)Aggregation of different sizes of induction motors (IM) connected to a power system has diverse Precision on the identification of the aggregate model parameters. Earlier work on the aggregation accuracy of various motors ... -
Suitability of aggregation methods of induction motor models for voltage stability analysis
(2012)This paper focusses on the aggregation of multiple induction motors (IM) connected in parallel on the same bus into a single equivalent model using aggregation based on transformer equivalent circuit (method 1) and on ... -
A neuro fuzzy model of an induction motor for voltage stability analysis using continuation load flow
(2011)This paper uses the concept of the continuation power flow analysis used in voltage stability analysis.It uses the continuation load flow to plot the PV (pressure-volume) curves of an induction motor load. A neuro-fuzzy ... -
The effects of human resource outsourcing on organisational performance (a case study of Post Bank Kenya Ltd.)
(International Journal of Research in Commerce and Management, 2017-08)The study finds out that outsourcing has become a strategic human resource approach in our current competitive business environment. Companies involved in the practice need to stick to their core competencies and go for ... -
Challenges of change management on service delivery in the Administration Police Service in Muranga County
(INTERNATIONAL JOURNAL OF RESEARCH IN COMMERCE, IT & MANAGEMENT, 2017-08)Change is an inevitable part of life, a well-planned and formulated change, can produce positive results. Despite planning change, change is hard to incorporate, accept and appreciate. Change has an impact on the individuals ... -
Protein utilization in humans as affected by level of dietary fat
(Elsivier, 1996-01)The objective of the project was to determine the effects of level of fat with or without manganese supplementation of diets on protein status of humans. Fourteen healthy adult humans participated in a 61 day study in which ... -
Effect of Insulin Treatment or Zinc Supplementation on Vitamin A Status in Streptozotocin-Induced Diabetic Rats.
(Journal of Clinical Biochemistry and Nutrition, 1995)A Using streptozotocin-induced diabetic rats, we examined the effects of zinc supplementation and insulin treatment on the metabolic availability of vitamin A. All diabetic animals exhibited an elevated plasma glucose (>18 ... -
Streptozotocin-induced diabetes lowers retinol-binding protein and transthyretin concentrations in rats.
(The British Journal of Nutrition, 1996-12)Retinol-binding protein (RBP) and transthyretin (TTR) in the plasma, liver and kidney, retinol in plasma, and total vitamin A in the liver were measured in rats 6 weeks after diabetes mellitus had been induced by streptozotocin ... -
Streptozotocin-induced diabetes in rats is associated with impaired metabolic availability of vitamin A (retinol).
(The British Journal of Nutrition, 1996-04)Using streptozotocin-induced diabetic Wistar rats, studies were carried out to examine the metabolic availability of vitamin A in the plasma, liver and the retina of the eye. Control and diabetic rats were fed ad lib. on ... -
Strain variation in vitamin A (retinol) status of streptozotocin-induced diabetic rats.
(International Journal for Vitamin and Nutrition Research, 1996)Decreased plasma concentrations of vitamin A (retinol) and retinol-binding protein have been previously identified in human subjects with type I diabetes mellitus. The present study was undertaken to investigate the effects ... -
Food and Macronutrient Intake of Elite Kenyan Distance Runners
(Human Kinetics Publishers, 2004-12)The food and macronutrient intake of elite Kenyan runners was compared to recommendations for endurance athletes. Estimated energy intake (EI: 2987 ± 293 kcal; mean ± standard deviation) was lower than energy expenditure ... -
Isolation And Testing The Cholesterol Reduction Ability (in-vitro) Of Lactococcus lactis From Fermented Smooth Pigweed (Amaranthus hybridus) Leaves
(African Journal of Food Agriculture, Nutrition and Development., 2011)Probiotics are live microbial feed supplements, which positively affect the host animal by improving its intestinal microbial balance. Studies have shown probiotic activities of Lactococci isolated from dairy foods, which ... -
Nutritional vulnerability of older persons living in urban areas of Lake Victoria Basin in East Africa: a cross sectional survey.
