(CRC Press, 2010-07-26)This chapter will present the mechanism, techniques, and advantages of infrared (IR) drying for various food and agricultural products. The propagation of IR radiation from a source (considered as any material at a ... -
A perspective on proteomics: current applications, challenges and potential uses
(Academic Journals, 2010-08)Biological sciences are experiencing an ongoing information revolution. Proteome-wide functional classification using bioinformatics approaches is becoming an important method for revealing unknown protein functions. ... -
The Effects of Market Reforms on Irish Potato Price Volatility in Nyandarua District, Kenya
(University of Nairobi, 2010-08)In the early 1990’s, the Kenyan government implemented refor ms in the agricultural sector that affected the volatility of agricultural product prices. However, there is lack of empirical evidence on the effects of ... -
Diallel analysis of Snap bean (Phaseolus vulgaris l.) varieties for important traits
(Academic Journals, 2010-08-04)The breeding programmes of many crops use diallel analyses because of the genetic information they offer to breeders. Six morphological and agronomic traits of Snap bean (Phaseolus vulgaris L.) were studied to investigate ... -

Assesing the Drivers of Pollinator and Natural Enemy Community in Pigeonpea and Field Bean Crops
(The University of Reading, 2010-09)1. Arthropods are key components in agro-ecosystems providing critical ecosystem services to crops, such as pollination and natural pest control. The structure and functioning of these arthropod communities can be influenced ... -
Ad Hoc Network Hybrid Management Protocol Based on Genetic Classifiers
(Scientific Research Publishing, 2010-10)The purpose of this paper is to solve the problem of Ad Hoc network routing protocol using a Genetic Algorithm based approach. In particular, the greater reliability and efficiency, in term of duration of communication ... -
Resonant Length Formulations for Dual Band Slot Cut Equilateral Triangular Microstrip Antennas
(Scientific Research Publishing, 2010-10)The dual band equilateral triangular microstrip antennas are realized by cutting the slots of either quarter wave or half wave in length, inside the patch. In this design, however these simpler approximations of slot length ... -
Performance of Double-Pole Four-Throw Double-Gate RF CMOS Switch in 45-nm Technology
(Scientific Research Publishing, 2010-10)In this paper, we have investigated the design parameters of RF CMOS switch, which will be used for the wireless tele-communication systems. A double-pole four-throw double-gate radio-frequency complementary-metal-oxide-semicon- ... -
Design of Aperture Coupled Microstrip Antenna Using Radial Basis Function Networks
(Scientific Research Publishing, 2010-10)This paper, two Artificial Neural Network (ANN) models using radial basis function (RBF) nets are developed for the design of Aperture Coupled Microstrip Antennas (ACMSA) for different number of design parameters. The ... -
On the Design of Circular Fractal Antenna with U-Shape Slot in CPW-Feed
(Scientific Research Publishing, 2010-10)new ultawideband circular fractal antenna with notched-band characteristics is presented. A notched-band characteristic is achieved by employing a U-shape slot in 50 Ω feed lines. The ultra-wideband impedance matching and ... -
Rain Attenuation at Terahertz
(Scientific Research Publishing, 2010-10)Rain attenuation values were calculated using empirical raindrop-size distributions, which were, Marshall-Palmer (M-P), Best, Polyakova-Shifrin (P-S) and Weibull raindrop-size distributions, and also calculated using a ... -
Interference Mitigation in Satellite Personal Communication Networks Using Adaptive Antenna Arrays and Filtering Technique
(Scientific Research Publishing, 2010-10)We address the problem of interference as related to Satellite Personal Communication Networks (S-PCNs). Basic low Earth orbit (LEO) constellation is considered. The paper uses combined adaptive antenna arrays and adaptive ... -
Influence of Budgetary Controls on Service Delivery in County Government of Nakuru in Kenya
(2010-10)In spite of collecting revenue from their jurisdictions, none of the county governments is financially autonomous. They have to rely on the disbursements from the central government. The general objective of this study ... -
Incidence and Extent of Substance Abuse among Secondary School Students in Nairobi Province, Kenya: Implications for Specialized Intervention
(Kenyatta University, 2010-10)Substance abuse has become a major challenge in secondary schools in Kenya. A study carried out in Kenya observed that 20% of adolescents aged between 12 and 22 years smoke cigarettes, 9% smoke bhang while 23% drink ... -
