1. Materials and methods 1.1. Microorganism The P. aeruginosa 15GR is a RL hyperproducer mutant obtained by gamma radiation of P. aeruginosa isolate P6 in our previous study (in press). This isolate was stored in Luria Bertani broth (Lab M, Topley house, England) containing 20% glycerol at -80 °C. 1.2. Culture media The mineral salts medium [9] containing glycerol 2 % v/v as the carbon source (GMSM) was prepared and used in this study. 1.3. Fermentative production of RL 1.3.1. Seed culture…

Water is an important resource needed for our subsistence & is required on a global level. The various hydrologic cycles are necessary in order to preserve the balance of our ecosystem. Thus, good quality water is necessary for our survival. Chemical & biological composition are two criteria for evaluating water quality. Water hardness can be defined by the presence of divalent cations dissolved in a water sample. The divalent cations usually present are Ca2+ & Mg2+ and these cations bestow…

Development of an Automatic Car Parking System Abstract—This Paper proposes the development of an Automatic Car Parking System imparting performance. This proposed framework uses sensors, electric power steering, path planning, path tracking and pure pursuit algorithm. The verification of the vehicle was demonstrated using the electric power steering for tracking the path. An ultrasonic sensor is used to determine the availability of the parking space. Drivers can uses user interactive interface…

Figure 3. Possible reaction mechanism for the decomposition of ammonium perchlorate. Based on the findings from all of the used techniques, the species formed in the beginning are ammonium ion, oxygen and chlorine species. The decomposition products of ammonium ion were hydroxylamine, ammonia and nitrogen dioxide. The perchlorate ion loses one of the oxygen atoms and forms chlorate ion. The ammonia is lost in reaction through formation of hydroxylamine, which is formed in reaction between…

The National Aeronautics and Space Administration’s (NASA) Mars Exploration Rover Mission (MER) is an ongoing space exploration mission of the planet Mars utilising two robotic rovers named Spirit and Opportunity launched on June 10 and July 7, 2003, respectively from Cape Canaveral, Florida, USA [1]. The mission’s primary goal is to “Determine Whether Life Ever Arose on Mars” (NASA) through the search for clues in soils and rocks that suggest past water activity on the planet’s surface. The…

Pollution is one of the most serious problems that affect our environment, and its effects on all life aspects are clear to everyone. Because of this, pollution is one of the most serious issues that all the word countries are concerned about. As time goes, the pollution problem increases and also the population growth increase. The increase in demand for water and food supplies place an increasing stress on the ground and surface water quality and quantity. One of the environmental problems…

Introduction GlaxoSmithKline, known as GSK, is an established pharmaceutical company that originated from the British. It was formed by the merger of Glaxo Wellcome and Smith Kline Beecham which from the past till now, operates globally in the science industry that later on got into the ranking amongst the world’s top ten largest companies after rising in the year 2000. Glaxo Wellcome, which consisted of Glaxo’s and Burroughs Wellcome became one of the world’s third major pharmaceutical company…

fluorometer. After each initial reading, the cuvette was removed from the fluorometer and 30 μL of 0.1 M HCl was added. The solution was gently mixed and the sample was re-analyzed with the fluorometer. Pure chlorophyll a was used to find sensitivity calibration factors in order to calculate the concentration of chlorophyll a in the filter samples based on EPA Method for In Vitro Chlorophyll a analysis by Fluorescence (Arar, E.J. and Collins, G.B.,…

This shows Onychonycteris finneyi, a bat fossil. The image shows its wing digits widely spread out with small claws on tip of each finger. It also shows the long tail found in earlier bat fossils (Moskowitz, 2008). Molecular Mechanisms The origins of bats wing muscles, molecular and cellular mechanisms are unknown but this research shows that the wing muscles of bats come from “a multiple myogenic source of different embryonic origins” (Tokita, Abe, && Suzuki, 2012). The results conclude that…

Germany: A Land of Tradition and Contrasts Organization and discipline are evident in everyday life for Germans. Public transportation operates like clockwork; traffic lights are synchronized, even retail stores are subject to Ladenschlussgesetz (store-closing law) (Somers 20). Everything done in German lives is done with order and efficiency. While we consider the German people in this light, they give us the impression of drones, adamant about following rules and regulations, and striving for…
