Summary Of Proposed Research

Global drought not only affects the world agriculture and economics, but interactively affects the phenotypic trait of plants across a different diversity gradient. Nevertheless, plants are able to adapt themselves to the drought environment by changing their phenotypic trait. From previous research at Jena Drought Experiment, in Germany, the results show that diversity not only has the capability to increase community’s resistance to drought, but also to increase community’s recovery ability after drought. On the other hand, the results show that the drought environment makes a strong selection on both, the plant phylogeny and functional trait. Yet, ...

Introduction Common materials used in deconstruction, renovation, and demolition sites include wood, bricks and blocks, concrete, metals and glass. They may be discarded now, but they can still be reused and recycled into other products in many ways. Typically, disposal of construction wastes are done through recycling, incineration, and disposal (Ackerman and Gallagher, 2002, Ganiron, 2014a). The construction wastes have great potential for the mitigation of the environmental impacts as based upon the material’s life cycle (Knoeri et al, 2013). Aim This project deals with the process of recycling the pulled down ...

The purpose of this study is to investigate the substantial effect that invasive species such as the dreissenid mussel, popularly known as quagga and zebra mussel have on the ecosystem of freshwater water Lake called Great Lakes with the potential impacts and how it can alter their ecosystem.

Introduction

Quagga and zebra mussels started thriving Great Lakes of North America in the mid-1980s being introduced into the lake by ballast ship. They are a minute bivalve and indigenous to the Caspian Sea section. After a short while, the population exploded invading the water bodies including its drainage systems and other ...

Introduction

As the need for energy conservation and preservation of the environment becomes more popular, many countries and firms are now utilizing renewable energy in order to generate power. Renewable energy, also known as green energy, is defined as the energy that comes from natural resources which can be replenished constantly, such as sunlight, tides, wind, biomass, and geothermal heat. Because the sources of this energy can be constantly renewed, it can be said that this type of energy cannot be exhausted completely (Ciolkosz).

Why Use Renewable Energy Sources?

There are many advantages in using renewable energy. First off, renewable energy is environmentally sustainable. Unlike ...

Introduction

With the escalation in cost production and environmental concerns, researchers have in the recent past focused in investigating resourceful means of increasing yields while reducing fertilizer use. Arnall & Godsey assert that the seeding rate and hybrids that promise the highest crop populations is continuously sort by corn cost cultivators worldwide (2013). Nielsen et al. notes that the crop populations are tied to the end yields. Corn populations have greatly increased in Indiana over the past thirty years to make about 340 plants ...

The issues faced by the Indian River Lagoon is quite similar to that of many rivers, lakes, and even oceans from various locations of the world. The steady decline in the marine population of the lagoon escalated to alarming rates by the end of the last decade. A few legislations that were passed in the early nineties to limit trawling in the estuarine region and as well as the direct dumping of untreated sewage wastes, had proved effective in the past. But later into the decade, the rescue efforts to salvage the lagoon and the ecosystem associated with it, ...

A Fossil fuel power station is a plant location where fossil fuels are burned producing electricity. Such fossil fuels include petroleum, natural gas, and coal. There are power plants which are designed for continuous operations for large scale purposes called central station fossil fuel power plants. Fossil fuel plants in many countries are used in the provision of electricity. They have machines for conversion of heat energy from combustion of fossil fuels into mechanical energy that operates an electrical generator producing electric currents (Camus et al. 154). The Samso Island is planning to exhaust the application of fossil fuels ...

Algae are a diverse group of organisms that are mainly autotrophs. Autotrophs are organisms that mainly produce complex organic compounds by using simple inorganic molecules and light or in other instances by chemical reactions. Algae can be broadly classified into two main groups which are unicellular or multicellular. Seaweeds form the largest and most complex marine type of algae (Olanrewaju, Wan Nik, & Kader, 2013). It should, however, be noted that algae can further be classified in many different ways. Below is an illustration of some of these classification representations. Green algae are classified into the Plantae kingdom and are, ...

Introduction

Modern technological trends are moving towards the application of sustainable energy resources. Sustainable energy is that which is balanced on the lines of consumption and supply (Berndes, 2003). Concerning this, the utilization of such energy sources promotes the maintenance of controllable collateral implications. Sustainable energy leads to insignificant levels of environmental degradation. Additionally, the sustainability of energy resources can be understood according to their longevity. Such sources are deemed to fulfill the needs of the present while guaranteeing their progressive benefits into the future. Sustainable development has become a mainstream topic that is addressed in various forums globally. Hitherto, ...

What is renewable energy? Renewable energy is defined as a form of energy that is collected from sources that are naturally replenished on human timescale, this include the sun, tides, wind, rain and geothermal heat. Starting a company in the field of renewable energy would involve deciding from the major sources which of the renewable energy source is best suited for their endeavor. The area of renewable energy can be divided into four main areas that it provides energy for; electricity generation, a transportation, water and air cooling/heating, and rural energy services. Based on a report by REN21 2014 ...

Motivation for the Study

Many automobile manufacturers in car producing countries are taking an interest in the renewable fuels as an alternative energy source for vehicles. This is due to the challenges caused by the difference in demand and supply of conventional energy sources like fossil fuels and the environmental degradation associated with them (Liu, 2015). Renewable fuels are more efficient than the current fuels used to power vehicles and their use will significantly reduce the fuel costs incurred by consumers. Renewable energy sources cause minimal environmental pollution, and its utilization will reduce the world’s pollution levels. The use of renewable fuels ...

Introduction

Alternative energy is a general term that is used to refer to any source of energy that is serviceable and is intended to be used as a substitute for other fuel sources without undergoing any undesired consequences. Hydrogen is therefore ideal alternative fuel energy for Army after Next (AAN) platforms. However, considering the current technology, use of Hydrogen as a form of alternative energy, has two setbacks that hinder its use as substitute energy. One of the setbacks is that, Liquid Hydrogen which is the ideal form of hydrogen needs four times storage space of convectional petroleum –based fuels. The other ...

The paths of water through the hydrologic cycle

One of the most fundamental principles in hydrology and ecology is the hydrologic cycle. This cycle represents the process of water circulations from the oceans, atmosphere, land and back to the ocean. The energy driving the cycle is from the solar/sun and forces of gravity. The process is continuous, and is a global wide process ensuring that every water drop on earth is part of the system (Harper et al n.d).

At the beginning of the process, water from the seas, lakes, wetlands, rivers gain energy from the sun and get transferred to the atmosphere as vapor. The sun provides ...
