Dexter Morgan, age 42, blood splatter analyst for the L.A.P.D., hardworking, focused, and determined, a serial killer of serial killers. Wait, what? That’s right, a man seemingly just like you and me harbors a substantially large secret. But don’t all of us harbor secrets as well? Secrets that we don’t want anyone else to find out? Is this why we’re so drawn to people like Dexter Morgan, the anti-hero? The answer is yes because secretly they are representations of our own unconscious. Whether we…

Introduction: The main purpose of this experiment was to take the Gas Chromatography/ Mass Spectrum part of the “Analysis of US bills for cocaine using gas chromatography / mass spectrometry” lab and improve upon the gas chromatographic results. This would be done by finding a way to separate the peaks of cocaine and doxepin. The lab done previously showed the use of two different methods to obtain samples of cocaine and doxepin for spiked dollar bills. The two extraction methods were…

Observe Ligand-Protein Interaction using Gel Filtration Chromatography (Phenol Red Binding to Bovine Serum Albumin) Introduction: Serum albumin is often known as blood albumin, and is the most abundant protein in humans and other animal plasma. Serum albumin is also known as a carrier protein by non-specifically binding several biomolecules. It is essential for maintaining the osmotic pressure that is needed for body fluids distribution between body tissues and intravascular compartments.…

Raju Chandra et al; A reliable and reproducible reversed-phase high performance liquid chromatography (RP-HPLC) was developed for the quantitative determination of quetiapine fumarate from marketed bulk tablets. The active ingredient of quetiapine fumarate separation achieved with C18 column using the methanol water mobile phase in the ratio of 30:70 (v/v). The active ingredient of the drug content quantify with UV detector at 359 nm. The retention time of quetiapine fumarate is 5.27 min. A good…

Adsorption is the bond of particles, particles, or atoms from a gas, fluid, broken down and attached strongly to a surface. This procedure makes a film of the adsorbate on the surface of the adsorbent. This methodology varies from absorbtion, in which a liquid (the absorbate) pervades or is absorbed by a porous solid. Adsorption is a surface-based procedure while absorption includes the entire volume of the material. The term sorption envelops both methodologies, while desorption is the converse…

Light spectroscopy has become an incredibly useful tool in analyzing the structure and composition of compounds. Specifically, the principles of absorption, the process by which an electron absorbs radiation to excite from a lower energy state to a higher energy state, and fluorescence, the emission of photons when a material is subjected to radiation, allow for the identification and analysis of unknown concentrations of compounds.1 With that being said, the purpose of this experiment is to…

The aim of this experiment was to investigate which technique – out of gravimetric analysis and colourimetry – was the most appropriate and accurate method to practice when calculating the percentage yield of a reaction. When examining the data obtained from the investigation, there was evident that there were some trends in the results. For the three graphs showcasing the results for gravimetric analysis in task one and task two, there was no general pattern. This was due to the fact that in…

Introduction: This Laboratory experiment mainly focused on the fundamental concepts of basic Chromatography. We had a goal of learning about the properties of color additives, studying their molecular structures, and their rates of solubility when added to a strip of paper and temporarily placed into a beaker of solution. When actually performing the experiment, it is relatively easy and straightforward to do as long as you do not increase the concentration of the dye or leave the wrong side of…

CLINICAL SUMMARY: DOI: 5/11/2012. Patient is a 48-year old male truck driver who sustained a work-related injury to his back when he was rear ended by another party. Patient is status post bilateral L3-L4 and L4-L5 left-sided and sublaminar laminotomy with neuroforaminotomy; and synovial facet cyst resection at left L4-L5 per the operative report dated 04/20/15. MRI of the lumbar spine dated 02/03/16 revealed transitional lumbosacral junction, sacralized L5 and rudimentary L5-S1 disc;…

My project uses optical illusions to compare gender and see if there are any major differences in how men and women perceive images. But what exactly is an optical illusion? Is age a factor in what the subject is seeing as well? My objective is to construct an experiment to determine whether there are differences between the sexes and how each view certain illusions. My hypothesis is that men and women will perceive or view images differently due to the manner in which their brains process…
