slow and with low capacity. Therefore we need attention to the choice of materials. 2‚ the composition of the materials: Impact crusher before the material containing the powder‚ the more the more affect the system of sand‚ because the powder easy adhesion of delivery. Therefore‚ the powder content of the materials in advance should a sieve. Select fine powder as far as possible from the material‚ so as not to affect the normal working of the impact of sand making machine. 3‚ Impact crusher materials

HISTOLOGY: EPITHELIAL TISSUE o Human body composed of 4 basic types of tissue: epithelial‚ connective‚ nervous and muscular o Formed by cells and molecules of the extracellular matrix o Connective tissue: characterized by the abundance of extracellular fluid o Organs can be divided by parenchyma (composed of cells for main function of organ) and stroma ( supporting tissue) o Except in brain and spinal cord stroma made of connective tissue o Epithelial tissue: covering‚ lining protecting surfaces

despite these advantageous properties‚ when used in conjunction with cationically electrodepositable primer compositions in automotive applications‚ adhesion is poor and yellowing of the topcoat composition results. Historically‚ polyaminoamides which are art recognized adhesion promoters‚ have been utilized in an attempt to deal with the above adhesion problems. These‚ however‚ can adversely affect the stability of the plastisol based sealant composition‚ the cure of the topcoat and in addition‚

and adhesion. Adhesion is an attraction between two substances of different states (such as a liquid and a solid). An example of adhesion is water sticking to a glass. “Adhesion of water to the walls of a vessel will cause an upward force on the liquid at the edges and result in a meniscus which turns upward. The surface tension acts to hold the surface intact‚ so instead of just the edges moving upward‚ the whole liquid surface is dragged upward. Capillary action occurs when the adhesion to the

CHAPTER ONE INTRODUCTION 1. OVERVIEW OF FOUNDATIONS The word foundation is derived from a latin word fondare meaning to set or ground on something solid. A foundation is that part of a structure which transmits the weight of the structure to the ground in a manner that the soil below does not fail in shear and the settlement is within the safe limits. Foundations are broadly classified into two categories: • Shallow Foundation • Deep Foundation
