The underground man, according to the narrator, is a fictional character who represents certain people in society. According to the narrator, the underground man is described as being someone who is filled with bitterness towards society, and finds himself powerless to act against it or within it. The underground man is a retired government service official. he is described as a nasty man, who on many occasions would take pleasure in being a spiteful official. One of the main themes in this text…

“I don’t know. I’m making this up as I go” said by Indiana Jones, perfectly describes how Steven Spielberg wanted the movie to be charismatic, charming, and funny as he admitted that this was, “the first movie where I actually shot the movie without thinking.” From native tribes and snakes to Nazis, it seems Indiana Jones can’t keep himself out of trouble when it comes to searching for lost treasure. That being said, his adventures are a roller coaster with twists and turns that you would least…

characterization The Roman spectrum of Cr-DLC coating was shown in Fig.1. The overlapped D peak and G peaks located at 1363cm-1 and 1564cm-1 were obtained after fitted with Gaussian curves, respectively. It’s well known that the content of the graphite crystal was closely related to the value of ID/IG [22]. And the ratio of intensity between D peak and G peak (ID/IG) of Cr-DLC coating could be calculated by the fitted curve. The value of ID/IG was about 1.98, which meant the sizes of sp2…

“DEVELOPMENT AND VALIDATION OF STABILITY INDICATING METHOD FOR SIMULTANEOUS ESTIMATION OF CEFTRIAXONE AND TAZOBACTAM INJECTION USING RP-UPLC METHOD” 2.1 OBJECTIVE To develop and Validate Stability Indicating Method for simultaneous estimation of Ceftriaxone and Tazobactam in their combined dosage form by RP-UPLC method in various stress condition like, alkaline, acidic, oxidative, thermal and photo degradation. 2.4 METHODOLOGY 2.4.1 Chromatographic Condition Column Separation was achieved by…

High performance liquid chromatography (HPLC) is a separation technique utilizing differences in distribution of compounds in two phases; called the stationary phase and the mobile phase. The stationary phase designates a thin layer created on the surface of fine particles and the mobile phase designates the liquid flowing over the particles. Under a certain dynamic condition, each component in a sample has a different distribution equilibrium depending upon the solubility in the phases and or…

The chromatography was performed on an ACQUITY TM UPLC system (Waters Corp., Milford, MA, USA). The UPLC system included quaternary solvent manager, a binary pump, degasser, autosampler with an injection loop of 10 μL and a column heater-cooler. The separation was performed on Acquity UPLC BEH TM C18 column (50 × 2.1 mm, i.d., 1.7 μm, Waters, USA) maintained at 40 °C. a mobile phase of acetonitrile containing 0.1% formic acid and aqueous 5 mM ammonium acetate buffer containing 0.1% formic acid…

Introduction: Acetaminophen is a common pain reliever and fever reducer used to treat conditions such as head, muscle or tooth ache, as well as colds, fevers, and even arthritis. It is available in a tablet form to be ingested. These tablets are manufactured by a large variety of pharmaceutical manufactures including a great deal of generic brand companies. These tablets all have the same active ingredient, acetaminophen, yet each hold different inactive ingredients that can impact the overall…

molecular mass, charge, or hydrophobicity. (Ninfa 121) There are many types of chromatography processes that can be used in different experiments and scenarios. These chromatography processes on include Gel filtration, ion exchange, and high pressure liquid chromatography. However, in this laboratory session the process of affinity chromatography is utilized to purify a His-tagged protein RNase H. The Separation of molecules that happen during affinity chromatography is based on specific…

different concentrations of the inducing agent IPTG, large-scale growth of BL21-DE3 E. coli cells that over-express hS100A7, utilizing fast protein liquid chromatography (FPLC) with immobilized metal ion affinity and size exclusion columns, and ultimately using the purified protein product in setting up crystallization screens. I was unable to obtain any crystals of hS100A7 due to the usage of the protease inhibitor cocktail AEBSF after cell lysis, which is known to interfere with protein…
