HUMAN POLLUTION OF GROUNDWATER IN THE REGION OF BURIMI

Groundwater pollution is a worldwide phenomenon with potentially disastrous consequences. Most of the Earth’s liquid freshwater is found, not in lakes and rivers, but is stored underground in aquifers. Indeed, these aquifers provide a valuable base flow supplying water to rivers during periods of no rainfall. This paper presents a comprehensive study on the quality of surface and groundwater in an environmentally sensitive aquifer watershed strongly pressed by urban growth. The objective of the study was to assess the integrated effects of human activities and natural characteristics of aquifer environments on the quality of surface and groundwater using multivariate statistical techniques.... ...

AN ANALYTICAL INVESTIGATION ON BOLT TENSION OF A FLANGED STEEL PIPE JOINT SUBJECTED TO BENDING MOMENTS

Apparently no analytical method is available to analyze the bolt tension in a flanged pipe joint subjected to flexure taking into account the actual stress distribution at the joint. Conventionally, a method similar to the flexural analysis of beam is sometimes applied on the assumption that bolt tension is proportional to the distance from neutral axis which is far from the actual stress condition. In this paper, an investigation has been carried out to find the effects of various parameters relating to flanged pipe joint connection, so that a definite guideline on determining the bolt tension can be developed. In addition, results are compared with the conventional analysis.... ...

EFFECT OF MAGNETIC TREATED IRRIGATION WATER ON SALT REMOVAL FROM A SANDY SOIL AND ON THE AVAILABILITY OF CERTAIN NUTRIENTS

Ferro magnetism is a property of certain metals and alloys, while Para magnetism is a property of all materials and water is not an exception. When passing a magnetic field, irrigation water gain a magnetic moment and retain it for 24 to 48 hrs. Magnetic treatment of irrigation water depends on magnetic field intensity, composition of dissolved salts and velocity of crossing a magnetron of 0.5 inch diameter. In this work magnetic activation of 3 different sources of irrigation water, namely: Ismailia canal; El-Salam canal; Abou-Sewer well, caused a little effect on water analyses. However magnetic treated water undergoes several changes in its physical properties. It also exerts several effects on the soil waterplant system.... ...

INVESTIGATION OF THE EFFECT OF PLATE DIMENSIONS AND THICKNESSES ON THE IMPACT EFFECT OF A STEEL BALL

In this study, impact effect of a ball is investigated on different dimensions of plate geometries by using computational impact analysis. All modelling and solution steps are done by ANSYS LS-DYNA package software. A plate is fixed from its side locations and a steel ball is thrown towards plate. Standard steel properties are used in material properties determination. Kinematic hardening plasticity model is selected for investigating the plasticity behaviour of ball and plates. Increasing the speed and decreasing the thickness of the ball cause to increase stresses. The highest elastic strains occur in the results of the biggest ball diameter test. Less stresses and more stable results are taken with increasing the thickness of plate. Plastic deformations occur only in the impact tests of the highest ball diameter and the lowest thickness of plate results ..... ...
