Since the first planet orbiting a star other than our Sun was discovered almost 20 years ago, astronomers have detected over 3,000 exoplanets. Going forward, exoplanetary scientists have two major goals: detecting smaller, more Earth-like planets, and characterizing particular planets of interest. With the advent of the extremely large telescope (ELT) era soon approaching, these two goals will become increasingly intertwined as better instruments give us the power to study the atmospheres of…

SURGEONS MAKE CANCER CELLS GLOW BRIGHT GREEN TO REDUCE RECURRENCE The key to a successful cancer surgery is to remove every bit of the tumor. When surgeons are performing surgeries on their patients, it is important for them to get every cancer cell and tumor out; they have created this liquid which glows bright green on the areas in the body that have cancer so it is easier to remove and avoid mistakes. Between 20 to 50 percent of cancer patients who undergo surgery end up experiencing a local…

insects they keep at bay. Then the prey would multiply and eat until its food source ran dry, our crops and property being the food source. Imagine being able to climb trees, cliffs, to swim through rivers and oceans. Imagine being able to see in an infrared spectrum, lighting the night for you to explore. Imagine being able to taste…

ANALYTICAL METHODS Determination of λ max Gemifloxacin mesylate λ max is determined by preparing one standard concentration of 10μg/ml and scanning should be done. Preparation of 0.1N HCL 8 ml of hydrochloric acid is taken in 1000ml volumetric flask and dissolved with distilled water and then make up to 1000ml with distilled water. Standard graph of Gemifloxacin mesylate: The λmax of Gemifloxacin mesylate in 0.1N HCL was scanned in UV-Visible Spectrophotometer and found to have maximum…

10.1 SUMMARY The aim of the present investigation was to formulate Raloxifene Hydrochloride Liquisolid compacts, with coadministration of a bioenhancer, for oral bioavailability enhancement. The reason for poor bioavailability (2%) of Raloxifene Hydrochloride is low solubility (100μg/mL) and high hepatic first pass metabolism. According to BCS, Raloxifene Hydrochloride is considered as Class II drug, lipophilic and highly permeable compound. Therefore, formulating Liquisolid Compacts bearing…

NASA is the National Aeronautics and Space Administration. They are the U.S. government agency responsible for science and technology related to air and space(Dunbar, NASA.gov). NASA was created in 1958 at the beginning of the Cold War with the goal winning the Space Race (Sandra, NASA.gov). The Space Race started in 1957, when the Soviets launched the Sputnik satellite. They won the Space Race by getting a man to the moon first (Barry, history.nasa.gov). After Neil Armstrong walked on the…

to synthesize, purify, and identify p-nitroacetanilide using acetanilide as the starting material. To test for the purity and identification of our desired product, we gathered data from: Thin Layer Chromatography (TLC), Melting Point (MP) range, Infrared (IR) spectrum, Gas Chromatography Mass Spectroscopy (GC-MS), and Proton Nuclear Magnetic Resonance (1H NMR). TLC plate indicated the formation of our pure product due to the difference in Rf values between starting material and product, 0.83…

will be performed to determine if there was any change in the polymorphic form of the drug or to characterise and provide structure information of the physical state of the dipyridamole. X-ray diffractometry, differential scanning calorimetry and infrared…

Thanks to its carved topography, researchers have always suspected that Mars was once home to several rivers, lakes, and perhaps even oceans. There has even been some speculation about the existence of frozen water deep beneath the ground. However, finding evidence of liquid water in the present day, has been a little elusive. That is why NASA's September 28th announcement that confirmed the detection of liquid brine on the Red Planet caused so much excitement. The first indication of the…

Optical Fibres By Jaydan Fibre optics are wires made of pure strands of glass or plastic spliced together (weaved together). These wires are as thin as strands of hair so their can be millions of them in a fibre optic cable. The wires are in bundles called optical cables and are used to transmit digital information over long distances. Fibre optics can be used for telecommunication, networking, decorations, endoscopy and much more because they are flexible, carry much more information than…
