LITERATURE REVIEW ENVIRONMENT ASPECT Global warming has reached an alarming degree due to growth in CO2 levels inside the surroundings. Latest studies carried out at Mauna Loa Observatory (Hawaii, US) in December 2011 found that the concentration of CO2 in the air was nearly 391 ppmv. Therefore, it is vital to become aware of and enhance the technique of CO2 sequestration. In view of this, microalgae have been identified as a candidate for sequestering CO2. Besides mitigating CO2, they may
current flora of the wetland and by taking a water sample and sending it for testing. The test was to show what the types of algae and protozoa in the sample were and to determine the pH, orthophosphates concentration, conductivity level, concentrations of nitrogen as ammonia and nitrate as well as determining the amount of indicator organisms such as E. coli.

CHAPTER 2 Review of Literature This chapter describes about biological methods of ammonical nitrogen removal processes from waste waters, their advantages and disadvantages compared to heterotrophic bacterial ammonia removal processes. These methods include both aerobic and anaerobic methods of ammonical nitrogen removal, their drawbacks in view of performance, literature studies on simultaneous heterotrophic nitrification and aerobic denitrification, immobilization studies including materials for
Introduction: The aims of this experiment are, firstly, to investigate the ability of duckweed (Lemna minor) to remove nitrate pollution from water and thus act as an organic and inexpensive way of combating eutrophication in water sources. Secondly, the relationship between nitrate concentration and rate of removal of nitrates by duckweed shall also be investigated. The duckweed is expected to absorb the nitrates as it grows and therefore lower the levels of nitrates in the water. In addition to
CHAPTER 1 INTRODUCTION 1.1 Background of study Corals are the foundation species of tropical coral reef ecosystems. They directly facilitate thousands of associated species by generating the physically complex reef structure (Bruno & Bertness, 2001). Coral reefs are the underwater ecosystems were held together by calcium carbonate structures which is secreted by corals and also are the most diverse and beautiful of all marine habitats. Often called "rainforests of the sea", this is because coral
Nowadays, people are experiencing water shortage and water interruption because of El Nino that commonly occurs during -Ber months and summer, which is almost half of the year. Water shortage occurs when there is a limited amount of water source from our main water suppliers, like Maynilad. And if we experience water interruption, many people will suffer because there would be an insufficient water supply for people to wash their clothes, dishes, and even take a bath.

CHAPTER 1 1. INTRODUCTION Sea cucumbers (class: Holothuraidae) are a group of marine invertebrates which are found in nearly every marine environment also provide an important source of livelihood for many artisanal fishers throughout the world, particularly for the developing countries in the tropical and subtropical regions. The Sea cucumbers are a significant source of income to many coastal communities and fulfill an important roles in marine ecosystems (FAO, 2010). It is mostly distributed

1.1 INTRODUCTION TO THE STUDY Asset Management involves the corresponding of costs, opportunities and risks against the desired performance of assets, to achieve the organizational objectives. This harmonizing power need to be considered over different time frames. Asset also enables an organization to examine the need for, and performance of, assets and asset systems at various levels. Additionally, it enable the application of analytical approaches towards managing an asset over the
CHAPTER ONE INTRODUCTION 1.1 Background of the study Dengue is an arbovirus disease complex which includes dengue fever (DF) and dengue hemorrhagic fever (DHF) and its subsequent dengue shock syndrome (DSS). It is caused by four serotypes of dengue virus. A dengue virus infection may be asymptomatic or it may lead to undifferentiated viral fever syndrome, dengue fever, fever hemorrhagic fever or dengue shock syndrome. (World Health Organization 2003) The disease is often, though not exclusively
