2.7 Farmers’ perception of soil erosion Perception‚ according to Lewin (1951)‚ one of the foremost authors in the behavioral studies‚ is a behavioral product of individual life space or what he also calls the psychological environment. To‚ Cox (1972)‚ perception is a “pieces of knowledge‚ which are acquired by the individual as a result of his visual‚ tactile‚ verbal and auditory contacts with the environment about him”. It is the stimulus/response aspect of the process of decision-making with the

Chapter 8 Flow in Pipes 8-76E Solution The flow rate through a piping system between a river and a storage tank is given. The power input to the pump is to be determined. Assumptions 1 The flow is steady and incompressible. 2 The entrance effects are negligible‚ and thus the flow is fully developed. 3 The flow is turbulent so that the tabulated value of the loss coefficients can be used (to be verified). 4 The elevation difference between the free surfaces of the tank and the river remains constant

The Effect of different soil types on plant growth Introduction Australian Gardeners are continually looking for better and cheaper options to improve the growth in their gardens. In Chinchilla‚ it is common to see rich vibrant coloured loam‚ but this is not suited to all plants. Common gardeners will find that it is important to understand what soil type they are on and how the climate conditions that surround the area may affect the growth of the plants they wish to establish‚ which contributes

Soil properties: Some physical and chemical properties of the soil were measured‚ which are presented in Table 1. The availability of nutrients and even contaminants depends on the degree of soil acidity. The most suitable pH for soil microorganism’ activity is 7‚ as nutrient solubility depends on soil pH changes (Riser-Roberts‚ 1998). The soil used in the present study has neutral pH and therefore does not limit the activity of microorganisms or the solubility of nutrients except for phosphorus

the cause(s) of road accident in developing countries is the mechanic who repairs the various vehicles before the vehicles hits the road. Though many attempted to suggest that a vehicle which is not roadworthy is a source of accident‚ they failed to propose means by which this could be rectified in a holistic way. Laws could be enacted to prevent vehicles not roadworthy from operating on the roads but between the two gaps the mechanic plays a significant role in preventing such road accidents occurring
