Dhaka is one of the oldest and fastest growing cities in the world. Due to rapid urbanization process, the city is emerging as a mega-city. During the last three decades, the average annual growth has been over seven percent which led to rapid expansion of Dhaka city both horizontally and vertically.  (Nahrin, 2008) Urbanization improves our material lives and comfort but brings many devastating consequences such as global warming, environment pollution climatic change and many more. As urbanization and industrialization is increasing day by day, it affects the global environment seriously. Unplanned and haphazard urbanization and industrialization is one the […]

Enoch goes about these powers and limitations, their

Enoch Powell, (1912-1998), was a British politician and the formerSecretary of State for Health in the United Kingdom (UK). Enoch Powell oncesaid “All political lives, unless they are cut off in midstream at a happyjunction, end in failure, because that is the nature of politics and of humanaffairs” (The Economist). The powers, which presidents areentitled to, have limitations, and so depending on how well the President goesabout these powers and limitations, their Presidency can either end very badly,in failure, or very well, in success. Some of the President’s powers includebeing the head of the executive branch of government, the commander […]

The the daily necessities of living, such as

The world we live in revolves around the culminationof various energy sources to operate the daily necessities of living, such asfood, shelter, electricity, transportation and much more.  The following paper will evaluate theconventional energy technologies used as well as alternative energy sources,and their impact on Earth.  Furthermore,the chemistry behind the functionality of the energy sources will be analyzed. One of the largest environment-impacting energysources used involves fossil fuel burning. Fossil fuels are hydrocarbons that are produced from the remains of deadanimals and plants.  Coal, fuel oil, andnatural gas are common examples of fossil fuels.  A hydrocarbon is an organic compound thatconsists […]

CHAPTER 1995) showed that the application of Cassava

CHAPTER1INTRODUCTIONPlasticsare made of polymers, since starch is a natural polymers and it isbiodegradable, starch is very favorable raw material in plastic making. Plasticdoes not decompose easily in the environment, so we come up with an idea inmaking biodegradable plastic. Biodegradable plastic is a plastic that decomposenaturally in the environment that end up with a result of having less harmfulenvironment. In this study, the researcher would like to obtain biodegradableplastic derived from starch-based material. The cassava starch will be used tomake biodegradable plastic to reduce non-biodegradable plastics. This will helpsolve the concern in environmental problem, climate change, pollution problemthat plastics contribute […]

Using Therefore the E. coli RuBisCO assembly system,

Using the E. coli RuBisCO assembly system, it may be possible to enhance the effectiveness of plant RuBisCo to increase crop yields. Simply increasing the total amount of plant RuBisCO would greatly impact total atmospheric CO2 fixation as well as plant growth. It has been calculated that even marginal increases in total enzyme quantity would have a substantial effect on total carbon fixation (Zhu et al., 2014).However, the most pronounced effects with be seen through selective mutagenesis, and the development of more efficient RuBisCo. This could be accomplished by site directed mutagenesis to increase RuBisCos affinity for CO2 and prevent […]

Life The acid water sea because as of

Life below water is one of the Sustainable DevelopmentGoals (SDGs) to make a better future for the world, oceans, and seas. This goalis to conserve and sustainably use the world oceans, seas, and marine resourcebecause oceans provide key natural resources including food, medicines,biofuels and other product. They help with the breakdown and removal of wasteand pollution, and their coastal ecosystem act as buffers to reduce damage fromstorms. Maintaining healthy oceans support climate change mitigation andadaption efforts. It’s also a great place for tourism and recreation. Evenmore, Marine Protected Areas contribute to poverty reduction by increasing fishcatches and income, and improving […]


Biology Name: Course: Institution: Instructor: Date: Biology The Polar bear is the largest predatory carnivore on land, which is found in the Arctic Circle that includes Arctic Ocean, the surrounding sea and landmasses. It is white yellow in color with a body that is elongated, longer nose and skull. It is found in countries like the U. S., Russia, Canada, Denmark and Norway. The average adult male polar bear weighs between three hundred and fifty kilograms and six hundred and eighty kilograms. An adult female weighs between two hundred kilograms and three hundred kilograms although when pregnant the weight can […]

A Day in the Park

Name: Instructor: Course: Date: A Day in the Park It was an awfully hot summer day. The perfect blue sky had no single cloud that covered it. The reflection from the sky was as smooth as glass. I could see myself through the pure water in the fishpond. Seeing the fishes jump up and immediately disappear into the water reminded me of the happiness I had when I first saw the dolphins in the zoo. The birds chirped delightfully as their songs broke the park’s silence. As they flew from one treetop to another, their colors intertwined creating a stunning […]

Global planet adequately warm to look after life,

                     Global warming is heatingup the earth. Worldwide cautioning happens when the nature populace and activitiesof human increase for the most part. These an Earth-wide temperature boostinfluencing such a large number of various satisfies everywhere throughout theworld. It is enlivening the dissolving of permafrost, ice sheets and frigidmasses which is causing ordinary sea levels to rice. The purpose behind anunnatural climate change is the extending measure of ozone exhaustingsubstances noticeable all around made by human exercises, like the expending ofoil subsidiaries or deforestation. These exercises convey a great deal of ozone […]

Carbon access to the heat from the hot

 Carbon dioxide emissions from the combustion of fossil fuels are directly linked to global warming and climate change. In 2010, the Carbon-dioxide emission was about 81.6 percent according International Energy Agency, and the emission was primarily due to the energy production and consumption. By 2020, the amount of Carbon emission will increase to 43.2 billion metric tons. It becomes necessary that we move towards relatively cleaner forms of energy. One such examples, is the Geothermal energy, which involves drilling into the earth’s surface to gain access to the heat from the hot molten rocks. Various technologies drive a geothermal plant. […]
