order to detect these sense motions the Nintendo Wii console uses a built in high performing infrared camera. This particular aspect of the remote’s functions became the focus for further research. The capability of the controller to detect motions offered‚ in Lee’s opinion‚ huge potential for a modified use of the technology. What he furthermore decided was to use the remote controller‚ with the infrared camera on top‚ together with a projector‚ to build his own interactive screen. His invention

OBJECTIVE: 1. To distinguish the bacteria abilities to metabolize various substrates and end products formed. 2. To observe the growth of different bacteria species in term of structures and its morphology based on different chemical substance applied. 3. To observe physiological and immunological properties utilized by different species of bacteria. INTRODUCTION: Bacteria biochemical testing can determine the types and numbers in terms of colony forming units of bacteria present in a

GlowstickWhat is a Lightstick and How Does it Operate? Lightsticks or glowsticks are used by trick-or-treaters‚ divers‚ campers‚ and for decoration and fun! A lightstick is a plastic tube with a glass vial inside of it. In order to activate a lightstick‚ you bend the plastic stick‚ which breaks the glass vial. This allows the chemicals that were inside the glass to mix with the chemicals in the plastic tube. Once these substances contact each other‚ a reaction starts taking place. The reaction

1 in vapour state sulphur partly exists as S2 molecule which has 2 unpaired electrons in the antibondind pi orbitals jus lyk oxygen and thus exhibits paramagnetism. 2 An interhalogen compound is a molecule whose atom contains two or more different halogen atoms (fluorine‚ chlorine‚ bromine‚ iodine or astatine). Most interhalogen compounds known are binary (composed of only two distinct elements). Their formulas are generally XYn‚ where n = 1‚ 3‚ 5 or 7‚ and X is the less electronegative

methods to produced acetone; however there are two methods that usually used which are reaction of propylene and benzene to produce cumene which produce phenol and acetone and the dehydration of isopropyl alcohol to produce acetone. According to ICIS‚ about 90% of productions of acetone are by using cumene process and with each tonnes of phenol can produce 0.62 tonnes of acetone. It also state that the production of acetone via the dehydration of isopropyl alcohol had been declined. The figure below

Mannitol salt agar is used to detect an organism’s ability to ferment mannitol‚ which lowers the pH of the phenol red containing medium. Phenol red is yellow below pH 6.8‚ red at 7.4-8.4‚ and pink at pH 8.4 and above. The coagulase test uses rabbit plasma to determine if the organism produces the coagulase enzyme in either the free or bound coagulase forms. Staphylococcus
