Small scale farming systems in the Western Highlands of Cameroon (WHC) are influenced by many factors. Understanding the determinants that influence the system is essential when targeting appropriate intervention strategies for improvement. A field survey was carried out and analysed to understand the forces that drive the farming systems in this area. The impacts of farming practices on farm sustainability were used as indicators to score sustainability. The results revealed that the household characteristics were very similar across the villages while the sustainability differed depending on the intensity of off-farm inputs in the production systems and other socio-economic factors...............

The present work describes the application of Canadian Council of Ministers of the Environment Water Quality Index (CCME WQI) for Hathikund station located along with Yamuna River India city. CCME WQI was applied using six water quality parameter (DO, BOD, pH value, FC, Ammonia and WT). Based on the results obtained from the index, the Yearly water quality of Hathikund River ranged between the ranges of 20-83 which indicate that river has the worst quality due to effect of various urban pollutant sources. This work confirms the need to take a serious action for monitoring the river for proper management...............

Based on American petroleum institute heavy oil iscategorized to have 10 and 20-degreegravity and a viscosity of thousands of centi-poises that flow under solution gas driveas the mean driving mechanism. thatensues in pressure decline experiments by way of investigationin many laboratory tests worldwide. It is alsobelieved to be avital recovery mechanism in some heavy oil reservoirs in the world, which have revealed more performance in recovery factors when it was compared to Darcy flow behaviour, however Darcy deals with single flow behaviour. Many scholars had investigated heavy oil properties for the past decades, and attempted to explain them................

An attempt has been made to study the variation in speed of a non-motorized vehicle with respect to three different parameters and to propose a model to simulate the speed of an NMV from the data obtained from experimental results. Fuzzy logic was used as a tool for linguistic classification of the premise variable in this model. As far as the simulation results are concerned it was seen that speed value obtained experimentally and obtained from the model are almost same. It was studied that all the three parameters have a significant impact on the speed of a non-motorized vehicle in a mixed traffic. It was seen that speed decreases with increase in number of PCUs in the same strip, speed decreases with increase in number of PCUs in the adjacent strips and speed increase when distance from the road edge increases.

This paper presents the structure properties of hair fiber reinforced concrete beams (HF-RCB). The main objective of this research was to investigate the potential advantages of hair fiber for improving the structure properties of reinforced concrete beams. Furthermore, the potential of hair fiber as part shear reinforcement by increasing the stirrups spacing of beams considered and verified the structure applicability of the proposed materials. This research carried out by two methods experimental and consequently numerical modeling. The experimental work focused on two beams..............
