AIR POLLUTION IN THE PHILIPPINES Guides and Tips Home / Blog / Air Pollution in the Philippines Air pollution is a common and frequent problem nowadays. When you are on your way to work‚ you pass by your neighbors’ backyard where he is currently burning their garbage from yesterday‚ then you come across a smoke-belching public utility vehicle‚ then a guy beside you lighted a cigarette and started suffocating you with second-hand smoke. You cannot always depend on your handkerchief on covering

eInsect attack is a serious agricultural problem leading to yield losses and reduced product quality. Insects can cause damage both in the field and during storage in silos. Each year‚ insects destroy about 25 percent of food crops worldwide. The larvae of Ostrinia nubilalis‚ the European corn borer‚ can destroy up to 20 percent of a maize crop. | European corn borer:A major pest in southern and central Europe. Insect resistant Bt maize is already being grown in Spain‚ France‚ Germany‚ Portugal

Metabolism’ in 1999. The study conducted examined the effects orally administered amino acids post resistance exercise has on protein synthesis and metabolism. The reason this study was conducted was to determine if taking amino acids orally‚ which is easily done‚ is just as effective compared to the less practical infusion of amino acids. The volunteers were six healthy adults‚ 3 male and 3 female. The volunteers had not participated in resistance training for at least one year prior to being a subject

pH indicators‚ in chemistry‚ are usually a weak acid or base that are naturally occurring in various plants and flowers and can act as dyes. Some examples of indicators are Litmus (Comes from a plant species called a lichen)‚ Phenolphthalein‚ Thymol blue‚ Bromocresol green and Universal indicator. All these indicators have a certain turning point in color once a certain concentration equilibrium of Hydrogen cations in reached (H +) or a certain concentration equilibrium of H3O+(Also OH - using Arrhenius

When embarking on technological change‚ an organisation must take into consideration the implications associated with this endeavour and the negative impact it may have. Let us take the rapid growth of Information Technology (a widespread and relatively recent technological change) as an example. With an increase in the amount of personal data in circulation‚ the need for data protection has also risen. This is best emphasised through the introduction of the Data Protection Act in 1998. Although

Effects of Changes in Physical Properties on Enzyme Activity By Alex Hoffmann First Individual Lab Report Wednesday 7:30-10:15pm 10/24/12 Meghan Duell Abstract The goal of this lab was to determine the effects of certain physical properties on enzyme activity. Enzyme activity was measured by the height of the bubbles that appeared after the enzyme was added which are proportional to the rate of the reaction when time is constant. The fact that enzyme activity is affected by physical

The Effect of Biological and Nonbiological Material on the Reaction to a Changing pH Level This experiment was conducted to learn exactly how biological material responds to rising or dropping pH levels in comparison to how nonbiological material does. The dependent variable in this experiment was how the different materials react‚ and the independent variable was the type of material‚ biological or nonbiological. Tap water was the selected nonbiological material‚ and the generally known pH level

Q.1 Culture as a tool to limit resistance. A shift from bureaucratic organizational practices toward post-bureaucratic‚ more flexible and less hierarchical systems of organization‚ where employees are empowered to cope with emerging changes and fluctuating demands by continuously reshaping their organizational roles and to contest the way decisions are implemented‚ has created a need for managers to move away from roles based on authoritative and rational forms of control to more culturally based
