Present study investigates the ability of using the damaged tires in the field of structural engineering. The proposed reinforcement material in this study represents an innovative approach to reuse strips extracted from used tires to increase the ultimate flexural capacity of thin flexural members, include thin timber beams and steel plates, satisfying clean environment and economic considerations by consuming the waste materials in the structural field. Results showed that the proposed reinforcement increases the ultimate flexural load value of the thin timber beam specimens in the range of 24.113 % to 30.809 % respectively based on results obtained experimentally and numerically by ANSYS software compared to specimens without reinforcement. Similarly, the ultimate flexural load was increased in the range of 83.95% to 101.7% respectively based on the results obtained numerically and experimentally for the rib type steel plates specimens. Also, deflection has been reduced due to the proposed reinforcement method.

There are many applications should be work online, these applications can be seen in the application layer of OSI reference model, each one of these consumes particular band width, bit rate and network speed depending of the resources that used to make any application operate for example there is a widely difference between video streaming network application and text chatting application. In this paper when any computer network needs to be examined, at least two different applications should be taken for example to monitor network performance when these application going to work and get in action. In this paper the researcher designed and a local area network to implement dedicated applications, monitor the network factors performance, get results, and compare between applications.

In this study, a simulation designs using a MATLAB is presenting to identify the characteristic of a solar energy panel as main feeding part, also, an alternative source represented by battery to compenstae the required missing energy on the load in case of low energy produced by a PV panel due to the effect of atmosphere condition on the solar energy in case of low radiation and temperature degree fall on it where a PV system as a whole works on feeding both of load and battery, but it may depend on the stored energy into the battery based on its capacity. In this purpose, different maximum power point techniques used in the PV system to extract the maximum energy. Perturb and Observe P& O, Incremental Conductance IC and Fuzzy Logic are the main common and modern techniques for tracking the maximum power.

Human waste is as important to mankind as life itself. As people feed for survival, the process of digestion leads to the production of human waste. Lagos being a Mega city with a population of more than fifteen million, the human waste generated is significant. How the generated human waste is handled is worthy of assessment. This paper examines the methods through which human wastes are collected and disposed in Ikeja residential quarters. The case study has the three classified residential zones of high density, medium density and low density. Sample frame was based on the number of buildings. Findings reveal that, residents across the density zones rely basically on septic tanks for human waste storage, which leads to a recommendation that septic tanks and soakaways be kept at appropriate distances to boreholes and wells, to prevent water contamination.
