Water pollution affects plants and organisms living in these bodies of water; and‚ in almost all cases the effect is damaging not only to individual species and populations‚ but also to the natural biological communities. Water pollution occurs when pollutants are discharged directly or indirectly into water bodies without adequate treatment to remove harmful compounds. Contents [hide] • 1 Introduction

Water Availability and Water Quality Water is the most precious natural resource that exists on our planet. Every living thing needs water in order to survive. If water becomes polluted‚ it loses its value and can become a threat to our health. Although we as humans recognize this fact‚ we disregard it by polluting our rivers‚ lakes‚ and oceans. Water availability has become a great concern in our world today. Out of all the available water on earth‚ only 3 % of it is fresh water. 77% of this

Forests are central to all human life because they provide a diverse range of resources: they store carbon‚ aid in regulating the planetary climate‚ purify water and mitigate natural hazards such as floods. Forests also contain roughly 90 percent of the world’s terrestrial biodiversity.[3] ---------------------------------------------------------------------------------------------------------------------

present an Automated Inventory System using Portable Data Acquisition (PDA) module to help thecompany’s growing business. The PDA module is composed of barcode scanner to scan issued and received items‚ and a Z8F6423 Zilog microcontroler to sore the information. A Product Inventory System (PIS) application program is also discussed to show how the PDA module can be interfaced with the PIS. Test results presented in this paper will show apparent improvement of company’s inventory system. 1.0 INTRODUCTION

Overview of Automated Grading Systems If bridges and buildings were made like we make software‚ then we would have disasters happening daily. I have heard this several times from many people. It is sad but true. Buggy software is the bane of the software industry. One of the ways of increasing software quality is by proper education. Several professionals from the software industry also attest to this. They believe that a greater emphasis should be given to quality and testing in university courses
