Since the water splitting reaction using semiconductor electrode reported by Fujishima et al. in 1972 [1], there is increasing interest in the development of metal oxide photocatalysts for environmentally friendly applications such as air purification [2], hydrogen production via water splitting [3] and the removal of organic molecules from water [4]. Recently, photocatalyst thin film has aroused growing interests instead of a powder type of photocatalyst. Photocatalyst film can be deposited…

contracts as directed by the MOF and proposed by the tendering committee. Zaina further reported that the BOD also resolved that Eric be allowed to conclude purchases and contracts without referring to the tendering committee for consumable goods like electrodes, scrap, iron ore, lubricants, and contracts of RM5 million and below. There was tend to make most decisions at own…

Parkinson’s disease is characterized by a progressive loss of control over skeletal muscle movements. This is caused by the degeneration of neurons deep in the brain that play a major role in initiating skeletal muscle movement (Human Biology p 135). There are many people that are affected by these diseases. Numerous tests have been done to improve this painful irritating disease, which worsen as the condition progresses over time. Parkinson’s affects different voluntary movement that people use…

Introduction In 1963, there was one of the most ethically controversial experiments ever conducted. The reasoning behind it? The actions of Nazi Soldiers during World War 2. At its helm was Stanley Milgram, a Harvard Graduate, who had the intelligence and foresight to create an experiment that would, with minimal bias, put to the test the compliance of human nature. His experiment would prove the true “nature of obedience.” (Milgram, Obedience to Authority: An Experimental View, 1974) Milgram…

How many of you are currently holding a grudge against someone? When somebody hurts you they take power over you, if you don’t forgive them then they keep the power. Forgive them and after you forgive them, forgive yourself. (Perry, 2005) Learning to let go of a grudge or forgive someone who has wronged you can be one of the most challenging things to do. However, letting go of grudges and granting forgiveness can clear the way for healthier relationships, less stress, improved heart health,…

case, they used electrophysiology to look more into the molecular basis and physiological response that occurs during mechanical reception transduction. The third experiment used a more in depth experimental design. The design consisted of two electrodes placed on bristles, one attached to the apical membrane while the other is on the basal. Observing a wild-type fly as their control, the researchers determined a normal response that occurs when a stimulus is sent to the fly. The mutated…

rapid, and reliable with little sample preparation required. The detection of acetaminophen via cyclic voltammetry is based on same oxidation of the molecule previously mentioned by the reaction in Figure 1 at the applied voltage of the working electrode, which results in a signal of measurable current proportional to the concentration.17 A plot of the current versus voltage results in a voltammogram which gives details on the reversibility of the reaction based on the peaks. Acetaminophen is…

In his article “The Experience Machine”, Nozick (1974) offers a thought-experiment which people can get any experience which they desire in a experience machine. In this paper, I argue that people should not plug into the experience machine. If I have a choice to plug into the experience machine, depending on my quality of life, I may or may not enter it. In Nozick’s description (1974), the experience machine can give people any experience that they desire. For example, if a person would like…

(“Light Your Way”) A flashlight is connected in a series circuit, meaning that all the components are connected in one big loop. The batteries are placed in a special way to allow the flow of electricity to run between the negative and positive electrodes. The spring underneath the batteries is linked to a contact strip, which is in contact with one side of the switch. On the other side of switch is another contact strip, which is connected to the light bulb and provides an electrical…

his arm, which he later used as a booster seat in the electric chair. Standing 5 foot 2 inches tall and weighing just over 90 pounds, his size (relative to the fully grown prisoners) presented difficulties in securing him to the frame holding the electrodes. Nor did the state's adult-sized face-mask fit him; as he was hit with the first 2,400 V surge of electricity, the mask covering his face slipped off, "revealing his wide-open, tearful eyes and saliva coming from his mouth ... After two more…
