While identifying new medicinal clues from the plant Salvia leucantha (Figure 1), Aoyagi et al. successfully isolated Salvileucalin B in 2008.1 Plants of the Salvia type have a very rich history in medicine. The name Salvia actually originates from the Latin word salvare, which means ‘to heal’. This isolated molecule exerts cytoxic activity against A594 (human lung adenocarcinoma) and HT-29 (human colon adenocarcinoma) cells with IC50 values of 5.23 and 1.88 µg/mL, respectively.1 Salvileucalin B
Intro: Organic chemistry is the scientific study of the structure of organic compounds. This includes the properties of the compounds and what occurs during chemical reactions. The structure of these compounds is found through analysing the results of Ultra violet spectroscopy. There have been many famous chemists over time who have made some ground breaking discoveries. None more so than R.B Woodward who almost single handily revolutionised the field of organic chemistry, winning a Nobel Prize in

After 1993, Cambodia economy has been increase rapidly and the scale of the city also expended but at the same time it leads to level up of air pollution (Furuuchi et al., 2006). Many emission sources of air pollution from anthropogenic are concerned, especially the rising number of vehicles has resulted in even greater pollution and growth in the population, resulted in a large amount of energy consumption: electricity, automobiles, household, field burning etc. (Furuuchi et al., 2009). Most of
Hydraulic fracturing, also commonly referred to as fracking, is a type of drilling for natural gas and oil that started in the 1940’s. In the beginning, when a well was slowing down, dynamite or TNT were placed inside the well head and detonated to help the flow of gas and oil by expanding natural cracks and veins in the earth. This method of fracking was used extensively for almost fifty years in the United States until the easy to mine and profitable oil had been almost completely tapped. A
Integrated Oil Companies and ExxonMobil Analysis Edwin Romero Ashford University BUS 690: Business Strategy Dr. David Kalicharan December 22, 2014 Abstract The Oil and Gas Industry is one of the oldest industries in the world, which plays a crucial role for the survival of mankind on this earth. As the future is demanding for nonhydrocarbon energy sources, we still foresee the need for oil and gas energies. We’ll look through a Strengths Weaknesses Opportunities and Threats (SWOT)
According to Devold (2013) Crude oil is petroleum liquid within earth that comprises of small components of metals and hydrocarbon, which is the combination of hydrogen and carbon dioxide. Crude oils have numerous elements that make them more or less attractive to refiners. Oil that is less sticky and flows more easily, is referred to as light crude oil, while stickier that requires heating in order to flow is referred as heavy crude oil. Light crude oil is used to mix finished products such as
As we talked and read about the oil topic in class, I first thought that oil was just the black stuff coming out of the ground. I then thought “how can I write an entire essay on just oil?” However, as we started talking, I realized that oil is really all of nature’s resources and these resources are slowly being destroyed. Nature is a resource that has been here for as long as people have. We use trees for paper, the rivers and lakes for drinking water and power, and oil for factories and everyday
The blowout preventer in the text “Rigged to Blow” by John Ballem is an important narrative element in the story. A blowout preventer is used the event of an oil pipeline rupture and helps to siphon off the oil from the main line and block off the remaining oil to ensure the least amount is spilled. It is a form of containment for the oil. In the literal context of the story, the blowout preventer is disarmed by unknown assailants. However, Ballem suggests that there is also figurative representation
Storing the Impossible: Hydrogen ("Thinkquest internet challenge," 2000) The earth’s supply of gasoline is slowly diminishing along with the cleanliness. In a desperate attempt to save precious gas, scientists have been attempting to find new ways to store and use energy. One way that scientists are consistently trying out is storing hydrogen. According to Demirbas(2001), “Because hydrogen can be easily generated from renewable energy sources and water, it has great potential as an energy source”

Today, being owned entirely by the Malaysian government under the Ministry of Finance, PETRONAS is entrusted with the responsibility to manage the entire nation’s hydrocarbon resources (Rig Zone, 2013) and to ensure the sustainability and orderliness of the country’s oil and gas industry is prolonged.

The portfolio project will be based on Duke Energy Corporation (DUK). Sector and Industry are utilities and electric utilities respectively. Duke Energy Corporation operates in three segments: regulated utilities, international energy and commercial power. DUK is an energy company headquartered in North Carolina. As a regulated utility company, more than 80% of the total assets are regulated (EEI, 2015), DUK is regulated by the Federal Energy Regulatory Commission along with many state service
Stop Frackin’ with the Water The amount of damage that has been done to our planet is not minute, and continues to grow. Most people like to believe that using natural gases has the ability to solve the problems that have been created over the years to the Earth. Now the question has been raised, is this really true? What if using natural gases is bringing more damage to our planet? One of the most controversial topics right now is based on the concern that water is being contaminated with poisonous
are way cheaper than hybrid cars. First of all you save over ten thousand dollars. Yet gasoline cars are very bad for the environment. Gasoline powered cars release pollutant gases into the air such as carbon monoxide, nitrogen oxide, or unburned hydrocarbons. Pollutants like these can cause major impacts such as the greenhouse effect which cause climate change. Based on the information of the traditional fuel, your major alternative is the hybrid car. A hybrid is a system which uses two different types
Fluidized bed reactors Large volume of fluid could be processed using the fluidized-bed reactors. It is mainly utilized for catalytic cracking of petroleum napthas in petroleum refining technology. When the small solid particles are suspended in the upward direction, fluidization begins. Nowadays its importance is utilized in wastewater treatment too (Yen and Yu, 1966). When a gas or a liquid is passed at very low velocity up through a bed of solid particles the particles do not move and the ΔP
There are three main fossil fuels; oil coal and natural gas were all formed hundreds of million years ago before the time of the dinosaurs (Energy Quest, 2012). The period of time that the fossil fuels were formed was the Carboniferous Period. It got the name from the word “carbon” which is the basic element in coal and other fossil fuels (Energy Quest). According to (Energy Quest, 2012) these fossil fuels were formed in prehistoric times from a material called peat which after enough pressure
My love for petroleum My father told me, civilization progress comes from the control of energy, so I was more sensitive on energy when I was young. Based on my father, an excellent geologist, I had better understand on how Earth form, how coal and petroleum form, and how energy comes from even though I was a little boy. I admire my father because he always teaches me the reality of the world. After that, I began to approach the energy world when I became a petroleum undergraduate student. Stepped
