Abstract: The desire for advanced performing renewable materials and friendly to the environment has grown worldwide. Lignocellulosic materials have demonstrated great potential as reinforcing agents in the manufacturing of composite materials. Achieving such materials also depends on the optimization of parameters not limited to particle size, temperature, duration of treatment, manufacturing technique and the type of modification. Laccase enzyme, a biological modification deemed friendly t...
Abstract: Modern-day diamond sorting is achieved through the application of X-ray lumi- nescence (XRL) and X-ray transmission (XRT) techniques. Sorting with XRL is limited to the class range of 1.25 mm to 32 mm because of self-absorption associated with larger dia- monds, greater than 32mm. The effect of self-absorption is also a high-energy phenomenon in XRL. XRT is limited to sorting large size diamonds as the technique suffers poor contrast for diamonds smaller than 10mm. XRT measurements...
Abstract: This study investigated the use of copper smelter slag for the removal of phosphorus from secondary wastewater effluent through batch tests. The media was physically and chemically characterized and showed presence of Fe2O3 (45.22%), SiO2 (14.98%), Al2O3 (3.21%), CaO (1.99%), SO3 (1.77%) and MgO (1.33%). Scanning electron microscopy monographs revealed smooth and flat surface and no heterogeneity on the surface of the slag with visible micro pores before the experiment and less vis...
Abstract: A lot of effort and time is utilized in the planning and building of the cellular wireless networks to use minimum infrastructural components to provide the best network coverage as well as delivery of quality of service. Generally, path loss models are used for the prediction of wireless network coverage. Therefore, detailed knowledge of the appropriate path loss model suitable for the proposed geographical area is needed to determine the coverage quality of any wireless network d...
Abstract: The advancements in hardware technologies have driven the evolution of vehicular ad hoc networks into the Internet of Vehicles (IoV). The IoV is a decentralized network of IoT-enabled vehicles capable of smooth traffic flow to perform fleet management and accident avoidance. The IoV has many commercial applications due to improved security and safety on the roads. However, the rapidly increasing number of wireless applications have challenged the existing spectrum bands allocated t...
Abstract: Wireless sensor networks (WSNs), an emerging large-scale network system can be embedded for any application. The designers of wireless sensor network have to consider the quality of service agreements from a user perspective. The WSN is very rapid in dynamic changing topology and has less energy, computing and communication resources.The network design has to fulfill the QoS parameters like reliability, timeliness and lifetime of the network. In wireless sensor network, when two no...
Abstract: Entire world is revolving towards digital space as a result of the Internet and other emerging web technologies are helping the society to reach the universe. ICT and e-learning are growing radically fast and have captured a major role in higher educational systems. To develop the coast-to-coast purposes, institutions are changing the teaching style from chalk and talk to Learning Management System (LMS), called e-learning systems. Impact of e-learning introduces various delivery m...
Abstract: Many countries desire to have a clean and healthy environment hence the need for effective and efficient Management of trash Bins. But for many years, the traditional way of collection and removal of trash has not proved to be effective. There are number of problems encountered with the usage of the traditional way of collecting trash in hospital and Healthcare Centers. These problems include among others: trash overflow, land and air pollution and unclean and unhealthy enviro...
Abstract: Renewable eco-friendly options for crop protection are fundamental in achieving sustainable agriculture. Here, we demonstrate the use of a biodegradable lignocellulosic banana-paper matrix as a seed wrap for the protection of potato plants against potato cyst nematode (PCN), Globodera rostochiensis. Potato cyst nematodes are devastating quarantine pests of potato globally. In East Africa, G. rostochiensis has recently emerged as a serious threat to potato production. Wrapping seed ...
Abstract: There is tremendous growth of data generated from different industries, i.e., health, agriculture, engineering, etc. Consequently, there is demand for more processing power.

The strength performance of UHPFRC with micro and hooked-ends steel fibers was studied in this paper using Finite Element (FE) modelling and simulation. The specimens were modelled in geometry, material, constraints, load and boundary conditions using ABAQUS package and dynamic explicit analysis was used to to investigate the crack pattern, failure mode and stress-stain behaviour of the UHPFRC specimens when subjected to uniaxial compression and tension loading. Results from the FE simulation...
ABSTRACT Current advancement in raw material utilization is gradually changing from the conventional petro-based materials into natural materials in order to arrest environmental pollution issue which arises as a result of the non-biodegradability of products obtained from petro-based resources. Plant oil among other alternatives due to its abundance, relatively low cost, non-toxicity and biodegradable nature have been found to be a potential replacement for petro-based feedstock in many in...
Abstract: Productivity is a very important aspect in any organization. Productivity means output obtained with respect to how much input is provided. To increase the productivity of any organization it is necessary to study and analyze the rejection data of that organization. This research focuses on the need of following a proper methodology in solving any particular problem. The defects were prioritized using QC tools, Pareto analysis. This research emphasizes on the importance of focusing ...
This study set out to estimate empirically the effects of fiscal decentralization on energy demand in Kenyan counties, 2013-2017. The finding of this study has established the critical role of decentralization in positively influencing electricity demand at the sub-national level through improved energy efficiency, rises in energy innovation and involving local actors in energy planning processes. This has been qualified by the ability of decentralization to provide necessary economic and fin...
