First National Communication of Kenya to the Conference of Parties of the United Nations Framework Convention on Climate Change
(2002)This paper discusses the risks that the city of Mombasa faces from the direct and indirect impacts of climate change. Mombasa is Kenya's second largest city and has more than 700,000 inhabitants. It is the largest seaport ... -
Finite-element analysis of non-uniform, lossy transmission lines
(1997)This paper presents an overview of the transmission-line matrix (TLM) method of analysis, describing its historical background from Huygens's principle to modem computer formulations. The basic algorithm for simulating ... -
Single-span, Continuous and Slender Deep Beams Made of High Strength Concrete
(1994)The current design recommendations for concrete deep beams given in the ACI Code, Canadian Code, CEB-FIP Model Code, CIRIA Guide-2, etc., are based on research results on normal strength concrete. As such, these design ... -
A Local Approach Methodology for the Analysis of Uncracked Tubular Joints.
(2004)In this study, the finite element method (FEM) is applied on a welded tubular T-joint, in order to analyse stress distribution in the vicinity of the weld fillet. The weld has been modelled all around the joint. A notch ... -
Determination of stress characteristics at Connections of Welded Members using Finite Element Method
(2004)Tubular members are used in various structural members. They have a pleasant effect and good aesthetic values. They can be used in large roof structures, offshore rigs, pressure vessels, etc. The connection between tubular ... -
Textile concrete: Preliminary mechanical characterization of a new ductile material.
(2003)The mechanisms of ageing and environmental degradation involving exposure to cyclic hot/cold temperatures, wetting/drying movements as well as exposure to a carbon dioxide (CO2)-rich environment, have different effects on ... -
Evaluation of pseudo-ductile behavior of textile concrete.
(2003)The influence of fibers on the fatigue cracking resistance of asphalt concrete is investigated using fracture energy. Nylon, a popular facing yarn of carpets, is used for the actual recycled carpet fibers in asphalt pavement. ... -
Textile concrete provides special architectural and permanent shuttering opportunities.
(2004)High Performance Fibre Reinforced Cementitious Composites (HPFRCC) are characterized by a stress–strain response in tension that exhibits strain-hardening behaviour accompanied by propagation of multiple cracks. This process ... -
An appropriate specimen geometry for direct tensile testing of textile concrete.
(2006)While the development of TRC (Textile Reinforced Concrete) in recent years is undeniable, validated experimental protocols and standards are slow to take hold. By drawing judiciously from previous studies, this work aims ... -
Effect of environmental exposure on the microstructure of textile concrete.
(2008)This paper presents the results of recent experimentation performed to study time-dependent changes in the mechanical performance of textile reinforced concrete (TRC) made with AR glass fibre and to specify the decisive ... -
Evaluation of toughness of textile concrete:
(2009)High Performance Fibre Reinforced Cementitious Composites (HPFRCC) are characterized by a stress–strain response in tension that exhibits strain-hardening behaviour accompanied by propagation of multiple cracks. This process ... -
Poisoning of Sulfate Reductions with Molybdenum in Anaerobic Reactors Fed Glucose
(1990)Several researchers have used molybdate (MoO42−) for the selective inhibition of sulphate reducing bacteria (SRB) in anaerobic digestion. The feasibility of using MoO42− for the control of sulphate reduction in biological ... -
Sulfide Toxicity in Anaerobic Systems Fed Sulfate and Various Organics.
(1993)Upflow anaerobic filters fed acetate and propionate, and completely mixed, suspended growth reactors fed acetate, propionate, lactate, and glucose were used to investigate the effect of electron donor and reactor type on ... -
Trends in Heavy Metal and Faecal Coliform levels in the Rivers of the Nairobi Region and Measures to reduce this Pollution.
(2005)he Nairobi, Ngong and Mathare are among the major rivers traversing the city of Nairobi, Kenya\'s capital city. The Ngong and Mathare rivers are both tributaries of the Nairobi River. The Nairobi river flows through the ... -
Cheap Engineering Solutions in Conservation of Natural Resources in Arid and Semi-Arid Lands,
(2006)Traditional economic behaviour is very much influenced by the environment. In the absence of sophisticated technology, environmental control over livelihood patterns and means of production becomes almost absolute. Since ... -
Assessment of the Biological Treatability of Black Tea Processing Effluent..
(2007)The anaerobic degradability of tea beverage processing effluent was assessed using a stationary upflow anaerobic filter. The filter, with an active column of 1.2m height, inner diameter of 100 mm and filled with rock as ... -
"Present and Future Energy Demand in Industry and Services Sector in Kenya
(1980)Energy service companies (ESCOs) are expected to play an important role in promoting energy efficiency in countries outside of the US. However, there have been no studies examining the current level of ESCO activity ... -
"Patterns of Transportation Household Energy Use of a Secondary City in East Africa
(1997)There is renewed optimism about the potential for leapfrogging in the rural energy sector of East Africa. By adopting highly efficient and renewable technologies many believe the region can rapidly bypass the conventional ... -
"Energy and Air Quality Assessment in Transport Industry in Kenya
(1999)We examine the links between fossil-fuel-based transportation, greenhouse-gas emissions, and health. Transport-related carbon emissions are rising and there is increasing consensus that the growth in motorised land vehicles ... -
"A Review of Commercial Renewable Energy Initiatives in Kenya
(1999)The objective of this paper is to provide a summary overview of the African energy sector and briefly examine the nexus of poverty and energy in the region. While the paper uses continent-wide data, the emphasis is placed ...
