mixed solution. 5. A mixture of ortho‚ meta‚ and para cresoles dissolved in cyclohexane may be analyzed spectrophotometrically because each exhibits an absorption in a region where absorption due to the other cresols is negligible. The absorption maxima occur at 752nm‚ 776nm‚ and 815nm for ortho‚ meta‚ and para cresols‚ respectively. To test the validity of Beer’s Law for solutions of cresols‚ each is made up in cyclohexane at a series of concentrations and the absorbances measured. Data obtained

Twin Towers; and intervening (or not) in the Syrian war are wrong. According to Gilbert Harman‚ such judgments about people’s actions are defective because they lack relativity to the individual’s moral framework. (Harman‚ 1975) In ‘Some Moral Minima’ Goodman argues that “there are certain things that are simply wrong.” (Goodman‚ 2010) I contend that right and wrong are subjective‚ based upon elements of an individual’s belief system‚ and dependent upon the situation. In this paper‚ I will

Headlights‚ airbags‚ and wheels theft are becoming the hottest and most stolen car items. They have found that it’s not financially related. It could be a jealous neighbor or acquaintance that will steal the wheels in spite. Basically if I can’t have them then you won’t either. As for wheels‚ I think the reason why theft is so high is because tires and rims are very high in price. The thieves can easily steal them and then place them up for sale on EBAY or other related classified ads. I actually

New and Future Developments in Cinematography This transitional period in cinema is currently resulting in new and inventive technology emerging in rapid succession. Because the age of digital cinema has only just begun‚ we have yet to see the full potential of what it might bring. In camera technology there are several new companies now competing with the larger names in the business. This is leading to a democratisation of an industry that

An intensive property is a physical quantity whose value does not depend on the amount of the substance for which it is measured. For example‚ the temperature of a system in thermal equilibrium is the same as the temperature of any part of it. If the system is divided the temperature of each subsystem is identical. The same applies to the density of a homogeneous system: if the system is divided in half‚ the mass and the volume change in the identical ratio and the density remains unchanged. According

Trans-resveratrol has long been known to exhibit antioxidant properties owing to the presence of three hydroxyl group which can readily scavenge any free radical either by donating a hydrogen atom or by forming a non radical product with the radical. Reactive oxygen species (ROS) and reactive nitrogen species (RNS)‚ the most potent of free radicals have been shown to be involved in initiation of heart and cancer related diseases by damaging DNA and other macromolecules in the body. It is associated

A pumpkin is a gourd-like squash of the genus Cucurbita and the family Cucurbitaceae (which also includes gourds).[1] It commonly refers to cultivars of any one of the species Cucurbita pepo‚ Cucurbita mixta‚ Cucurbita maxima‚ and Cucurbita moschata‚ and is native to North America. They typically have a thick‚ orange or yellow shell‚ creased from the stem to the bottom‚ containing the seeds and pulp. Pumpkins are widely grown for commercial use‚ and are used both in food and recreation. Pumpkin pie

Report on High Entropy Alloys(HEA) Introduction: Alloys can be defined as a mixture of two or more elements containing one or more elements containing one metal at the least. From bronze age ‚ alloys have been developed based on one principal element. Later metal matrix composites and inter metallic compounds gained attention. Development in technology and innovation lead to the idea of multicomponent system. These systems consists of multiple principal elements. This was attained by alloying

I am working on a project where I have to control a vehicle barrier gate like this: Our team has planned to work with Arduino but we are open to other suggestions. My question is‚ can I use a DC motor for this sort of task or should I look into AC motors? And what kind of motor should I use? Is this even possible using Arduino? I looked into some of the tutorials of automated garage door openers which kind of relates to what I am trying to do. But the problem is‚ most of them use commercial
