is rainwater harvesting, water recycling, landscaping and irrigation, water fittings, metering and leak detection. As the ancients and natives would attest, water conservation theory has been around since the beginning of time. Most societies that deal with a limited resource learn to use it wisely. The concept of integrating conservation into water planning has been promulgated in the U.S. for more than 60 years. In the 1950’s, for example, the Water Resources Policy Commission published A Water Policy

The hair follicle and skin cells are having sebaceous glands and possess glandular secretions, the constituents of which are directly related to the age and sex of an individual. Before the onset of puberty, the output from these glands tends to be low and increases through the teenage years till almost two decades. Beyond the fourth decade, sebum secretion decreases more in females than in males. Changes in the amount and composition of hair lipids results in lesser scalp hair density, lower growth
2. Review of Literature 2.1 Integrated watershed management Watershed management is the process of organizing and guiding land, water, and other natural resources used in a watershed to provide the appropriate goods and services while mitigating the impact on the soil and watershed resources. It involves socio-economic, human-institutional, and biophysical inter-relationships among soil, water, and land use and the connection between upland and downstream areas (Ffolliott et al., 2002). In essence
variety of green areas within cities, (Roy et al., 2012). These include all types of parks, sporting fields, private backyards and gardens, street trees, spontaneous vegetation, infrastructure easements, cemeteries, green roofs, vacant lots, nature conservation and other spaces that provide opportunities for active and passive recreation (Harnik, 2010). These green spaces literally cover both public
group report submitted earlier. 1.1.1. Overview This document contains information about the following aspects: i. Key areas of research undertaken as well as the sources which had to be referred as a contribution to the presentation including the literature related to each task assigned to me. ii. The key issues and conclusions learnt as a result of undertaking the group assignment on the given topic. iii. An indication of the way in which my individual contribution
chemical for it in terms of possible production of side products that could be inhibitory for the desired process later. I achieved a grip on that area involved in reaction by consulting senior engineer at the department working on biofuels and reading literature on the internet. I took care of reaction conditions and material used for reactors as I had gained knowledge of materials during the courses studied during environmental engineering program. I carried out multiple cycles for each treatment and also
According to the Greek philosopher Pindar, the best of all things is water. This view is notsurprising since the need for water, throughout human history, has always been appreciated. It is present everywhere, and without water, life, as it is known, will simply cease to exist. Water is constantly in motion, passing from one state to another and fromone location to another. Whether the water is in motion, or stationary as it is in lakes, itinvariably contains extraneous materials, some due to natural
increase. Data from the World Resources Institute (WRI) shows that 2.3 trillion tones of CO2 is added to the atmosphere in the last 200 years. CO2 emissions are currently 12 times higher than in 1900 as the world consumes more oil, gas and coal for energy. The impact of climate change can be seen clearly from the happening of earthquake, tsunami, flood and draught. Like all other countries in the world, Malaysia is also exposed to the risk of climate change. According to Tangang et al. (2012), the
