There are several approaches to producing transgenic species. This method is called DNA Microinjection. This works by introducing a new gene which has been previously been manipulated in vitro to contain the "ideal" characterizes. The modified genetic material is micro-injected into fertilized chicken eggs, and the eggs are then hatched. DNA is the "recipe" for how to build molecules, and RNA is a type of building block used in the body. Adding a stretch of DNA, the...
A cursory glance at recent news headlines reveals growing problems in the Malaysian built environment, e.g. landslides, floods, environmental pollutions and etc. On another front, the recent energy crisis also demands a re-look into the way we design, construct and operate our buildings. Various measures such as policies, regulations and environmental programs have been taken by Malaysian government to resolve these issues but the problems however, continue to exist. There is a growing...

Global warming is recognized to be the effect of increasing atmospheric greenhouse gases. In Australia, however, experts discovered that land use/land cover change (LUCC) has potential impacts on the exacerbation of climate change consequences. To address this issue, the Australian government calls for the execution of several methods to prevent further deterioration of the Australian ecosystem. Such steps are needed to reduce the harmful effects of long-term global warming in the Australian...
Though a majority of the world's current energy sources are non-renewable sources such as coal, oil and natural gas, we face a number of challenges like price rise, over dependence on a particular country and growing concern about pollution and climate change. It has become imperative for the government, businessmen and consumers to search for an energy source which is renewable. Generally, renewable energy resources are unlimited in availability but to tap them is a difficult task. The recent...
Generally, accessible to green space is more achievable in urban area compare with rural due to poor access condition in rural (Nature Nearby, 2010). Rural communities cannot expect to have same level of accessible which available to urban communities. They are expected travel further than urban communities to enjoy all type of facilities. (Communities and Local Government (former ODPM), 2002). However, among rural residents, they are expected basic facilities either within or immediately...
If one were asked, 'What is science?' they would probably reply that it is everywhere and no proper definition would be received. No one has a proper definition for science due to its diversity and vastness. Science has many forms and it is because of this that if noticed closely, one is surrounded by things that somehow involve science. Science is defined as the intellectual and practical activity encompassing the systematic study of the structure and behaviour of the physical and natural...
Reddy relied his topic mainly on the new renewable energy technologies which found to be very useful nowadays due to the increasing environmental concerns, increasing consumers' interests and the Government's support in the usage of the renewable energy advancements. He also focused on the barriers that are identified in the penetration of RETs He also mentioned the top priorities for a country like India to rely on renewable energy sources and also gave the barriers like infrastructure...
Biodiesel is a renewable, environmentally friendly substitute for petroleum-based diesel fuel. It is produced from vegetable oils, animal fats, or wastes cooking oils and fats, and can be used in existing diesel engines without any expensive modifications. Biodiesel can also be added to petroleum diesel to create a biodiesel blend with favorable performance attributes and environmental benefits roughly proportional to the biodiesel fraction. Biodiesel is safe, nontoxic, biodegradable, and...
The purpose of this project is to provide a feasible solution to solve the plastic waste problems and help residents in the Mekong Delta areas to improve the transport infrastructure. Specifically, this project is aimed to use plastic waste as an alternative construction material for building roads in the Mekong Delta areas. The modified-plastic road is designed to meet specific needs that were set to make sure the road would be suitable for the local environment and have an economic...
