In the future what climate will the earth have? Will it be too hot, were we will all have to live underground to stay alive and cool. Will we be in the next ice age, struggling to survive in the cold. Will glaciers cover the earth’s surface to the point where no plants can grow? Will we have destroyed the crops where we can no longer feed ourselves? Will it be the same as it is now, proving that climate change is just a political game? No matter what is in store for us in the future, Climate…

There is an invisible enemy exists nowadays who becomes much stronger in the recent years and ruins people’s health and lives gradually. This powerful invisible killer is called “Air Pollution”. Let’s close our eyes and take a deep breathe. How is the feeling of the air? Is it still fresh and feeling relaxed nowadays, or it turns into something uncomfortable with awful smelling? Most of the people think the quality of the air become stale. As an increase of countries processing industrialization…

of bitumen upgraded. Compared to refining conventional oil, upgrading tar sands (removing impurities and adding hydrogen) produces two to three times more sulfur dioxide (which causes rain), volatile organic compounds (producers of ozone), and particulate matter (a cause of heart and lung disease, Avery, pg 185). Environmentalists, as well as everyday citizens, have expressed concerns that these pollutants will add to global warming and the heating of our planet. In a time when the world is…

Packaging is significant both to consumers and producers. To the consumer, excellent packaging means good storage of products; thus, preventing them from contamination(Schafer, 2015). For instance, no one would want to eat poorly packaged food that may be subjected to contamination. The consequences may be dire and costly. Different materials have been used for product packages, but plastics lead the way in terms of the most frequently used packaging material by many industries globally. A large…

Mendeleev lived and worked before there was a consensus on the constitution of an atom. Were they solid and uniform throughout with only mass differentiating between elements, or were they particulate and composed of certain “sub-atoms”? Mendeleev staunchly adhered to the former theory and explained certain phenomenon characteristic of electrons and protons (valence properties, radioactivity) as a result of this ether (book). Proving its existence…

Table of content Introduction: The wastewater treatment plant (WWTP) of Amul effluent treatment plant, Dist. Anand having capacity to treat 400 KL/day of wastewater. A general systematic flow diagram of WWTP is shown in figure. The system was designed to handle to treat wastewater having high organic content and suspended solids. The heart of the system is Aerobic biological reactor. The system was designed to handle BOD at 20°C of 800 mg/L and Suspended Solids (SS) 250…

Imperial Sugar Imperial Sugar was known to be one of the largest sugar processing plants in the United States. The company employed over four hundred employees and contractors at its plant located In Port Wentworth, Georgia, just outside of Savannah. The facility covered over one hundred acres of land and is bordered by a river. The facility used conveyors to transport stored sugar from silos to the necessary areas throughout the plant. The Port Wentworth plant takes raw sugar cane and creates…

Nanoparticles (NPs) have piqued the interest of scientists because of their distinct physical, chemical and biological properties when compared to bulk material. These differences in characteristics can be attributed to the high surface-to-volume ratio (SA:V) of NPs compared to bulk material. Since NPs have a higher SA:V than bulk material, they are more reactive than their bulk counterparts; therefore, the surface characteristics of NPs can be easily manipulated. (Xuefei et al, 2014) Metal NPs…

Urban sprawl is an inattentive issue that continues to harm the future of the world, unless the problem is addressed. The concept of urban sprawl is the “uncontrolled spread of urban development into neighboring regions” (“Urban Sprawl”). Across the globe, there has been urban sprawl in major cities, without consideration of future consequences. As society focal point is on celebrities and fashion, the focus on the destruction of the environment is not being acknowledged. The sprawl leaves…

Over view of Meter dose Inhaler Regulation in US and EUROPE. Introduction A metered-dose inhaler (MDI) is a device that delivers a specific amount of medication to the lungs, in the form of a short burst of aerosolized medicine that is usually self-administered by the patient via inhalation. It is the most commonly used delivery system for treating asthma, chronic obstructive pulmonary disease (COPD) and other respiratory diseases. Metered-dose inhaler products contain therapeutically active…
