...Individual Assessments Working individually or on a team requires you giving yourself to your work. Depending on your personality it can either help you in your career, or hinder you within your team. On my team I have 7 individuals who work together will very different styles of personalities. Within those personalities there are the thinkers, master-minders, producers, assessor, and the perfecter. When dealing with personalities that include wanting to be right, fear of losing individuality, not like authority, natural curiosity, and someone who likes to have control it can become difficult not only to address those personalities but also to combine them in a team atmosphere. Double space throughout in APA Master-minder The master-minder with the cautious style is more guarded, less indirect, is overly analytical. This can not only help the team by being analytical, but it can also cause conflict if the other personalities see the master-mind as a threat. Since the master-mind does seem to take some calculated risks it does seem that this individual will jump in at times with issues regarding the workplace, but in the same aspect the over analytical factor can make others uncomfortable. Assessor. The Assessor with the cautious style has natural curiosity, they care what people think, procrastinator, and is very observant. The assessor would probably not become a leader within the group, due to them caring what others...

...The Burghers of Calais is a sculpture made by Auguste Rodin. This sculpture was made in the years of 1884-9 and is located in Calais, France. I believe that Rodin made his sculpture to be a sculpture in the round, which means that it is meant to be seen from all sides. The person viewing the work must walk or move around it to see the whole thing. There are four main ways to make a sculpture, which is carving, modeling, casting, and assembling. In this particular sculpture, Rodin used the casting method, I do not know what the original models were made out of but to mold it he used bronze. The history behind The Burghers of Calais is six top leaders surrendering themselves to be executed. Rodin was commissioned by the French city of Calais...

...article Art, the definition of art is “the concept that any form of creativity should be valued for its own merits alone, rather than measured against some fixed set of criteria that is laid down by the art establishment.” The second article the definition of Art “expresses human imagination, not least when it engages with humanity's destiny.” An example of painting "The Mona Lisa" by Leonardo da Vinci the painting is an Image of a lady smiling because she is pregnant according to the article The Art Newspaper. This painting goes with the second definition of art because it expresses how Mona Lisa feels about being pregnant. An example of sculpture is by Auguste Rodin “The Thinker Statue” the purpose of The Thinker statue was to represent the artist as himself at the top of the door reflecting, The Thinker is a man in sober meditation battling with a powerful internal struggle. The sculpture is a man with a pose with hand to the chin, right elbow to the left knee, and crouching position. An example of Architecture is by Gregory Ain he is known for “Dunsmuir Flats, designed in 1937, brought in Neutra's influence in greater measure, but also displayed Ain's own ideas, limiting building costs while combining both privacy and exterior light.” An example of photography according to worlds famous photos is by Arthur Sasse, he took a photo of Albert Einstein is one of the most popular figures he is considered a genius because he created the Theory of Relativity, and challenged Newton’s...

...Ada Lovelace was born in London on December 10th, 1815. Her parents were Lord George Gordon Byron and Lady Anne Isabella Milbanke Byron. They didn’t have a happy relationship, and Lady Byron separated from her husband weeks after Ada was born. A few months later, Lord Byron left England, and Ada never saw him again because unfortunately he died in Greece when Ada was 8 years old. Later on in her life, Ada’s mother hired tutors to teach her science and math. She believed that if Ada engaged in these, it would prevent her from developing her father's moody and unpredictable temper. In 1835, Ada married William King. They had three children together. Ada's health suffered after a case of cholera in 1837. Doctors gave her painkillers and her personality...

...This experiment will separate the components of a mixture on the basis of their differing absorptive tendencies on a stationary phase, which is the method of chromatography. The mobile phase will consist of four distinct transition metal cations dissolved in an acetone-hydrochloric acid eluent, along with three unknown solutions; the identities of these will be determined based on a comparison of the Rf value of these to the known cations. First to be prepared was the stationary phase, or chromatographic paper, which in this case was filter paper. Given only large sheets, it was cut into a rectangle with 20 cm length and 10 cm width. Before cutting, though gloves were put on so that skin oil would not stain the filter paper. Also, the filter paper was not laid on the lab table, but on a paper towel. With a pencil, a line was drawn 2 cm from the bottom edge of the paper. Marks were put on the line, 2 cm apart, and labeled with the appropriate cations and the unknowns labeled as U1, U2, and U3. The stationary phases were then spotted with the corresponding knowns and unknowns, then dried under a heat lamp. This spotting process was repeated 3 times. It was done using glass capillary tubes; these used adhesive and cohesive forces to draw up the cation solutions into the tube and subsequently released them onto the filter paper when touch. With the stationary prepared, the developing chamber was made. In a 600-ml beaker 9 ml of acetone and 1ml of 6 M HCl were combined (under...

...Gunshot Residue Analysis You are provided with cotton balls that were used to swab 2 suspect’s hands for the presence of gunshot residue. Determine, by atomic absorption spectroscopy, if either of the 2 have fired a gun recently. To do this you will first extract the lead residue off of the cotton ball and then you will run the lead samples and a lead positive sample and a blank to determine if there is lead in the residue from the suspect’s hands. Extraction/Sample Prep: 1.) Use tweezers or forceps to remove the cotton ball from its container and place it into a plastic centrifuge tube. Add 10 mL of 1% nitric acid and shake well. Continue shaking occasionally for 10 minutes. 2.) Remove the supernatant (the liquid in the tube) with a transfer pipet and place it into a labeled 25 mL volumetric flask. 3.) Add 1 mL of Ammonium dihydrogen phosphate solution. 4.) Dilute the contents of the flask with 1% nitric acid. 5.) Label the flask(s) as unknowns (1,2). Positive and negative control samples: 1.) Add 1 mL of lead standard to a 25 mL volumetric flask. 2.) Add 1 mL of Ammonium dihydrogen phosphate solution. 3.) Dilute the contents of the flask with 1% nitric acid. 4.)

...Representing Repression: A Psychological Reading of Menagerie Shih Ching-liang The Glass As the tradition of realism dominated in the late 19th century, expressionism emerged along with the rise of psychology at the very end of the century Expressionistic plays sought to give not the external reality or surface appearance of life but the inner reality, life as felt rather than as seen (Barnet 519). The Glass Menagerie is mostly expressionistic: the first sentence of the Production Notes declares that “it is a memory play.” The term “memory play” suggests that it is a play worked out in one’s mental process, rather than a realistic representation. Instead of external reality, the inner vision becomes the primary concern of expressionistic drama. Thus this paper focuses on the repressed state of each character in the Wingfield family, and tries to shed light on their inner psychology by means of psychoanalytical approach. As a mother figure, Amanda is quite distinctive from those in conventional drama. With the father absent for years, Amanda takes on not only maternal nuturing responsibilities but also the paternal disciplinary role. She is a breadwinner (though partly) as well as a caretaker. Yet in her attempt to fulfill this double-sided role, she actually encounters a series of frustrations and repressions, which provoke her to escape into the retreat of past. In the play, what characterizes Amanda is her poignant sentiment toward the Old South days. She believes in the...

...Statement of Goals The goal of the group project was to calculate the percent calcium in a natural calcium tablet from Prime Eastern Pharmaceuticals in order to compare it with the reported amount of 800 mg of calcium per tablet to determine the validity of complaints regarding a reduced amount of mineral in the multivitamin. The quantitative determination of the analyte was accomplished through three experiments: complexometric titrimetry, flame atomic absorption analysis, and potentiometry using an Ion Selective Electrode. The complexometric titrimetry involved titrating the unknown calcium solution made from the calcium tablet with standardized EDTA. Quantitative determination of the analyte calcium was possible due to the stable and quick formation of the metal-EDTA complex with a 1:1 reaction stoichiometry. Flame atomic absorption analysis is useful in determining the amount of analyte in an unknown because the measure absorbances of standard solutions can be used to plot a calibration curve that can be used to determine the concentration of the metal in an unknown solution. Potentiometry is useful for determination of analyte when an ion sensitive electrode is used to find the amount of ion in standard solutions. Week 1: Introduction and Background The first test for calcium in the multivitamin was complexometric titrimetry, a titration of a solution of calcium tablet with a standardized solution of EDTA. EDTA forms a stable complex with calcium metal with a reaction...

...Chromatography is commonly used to separate mixtures to determine different chemical components. The main types of chromatography include gas, thin layer, paper and column chromatography. Generally used most, paper has a stationery phase and a mobile phase in a chromatographical experiment. The stationery phase is the paper itself absorbing the solvent, while the mobile phase is the solute moving up the strip of paper. Solvents are solids, liquids or gasses that dissolve the solute, in this instance it separates the pigments of the ink so you can see what colours make the solute. (ABC, 2018) Each solvent has a different structure based on their dielectric constant. The solvents being used in this experiment are acetone, acetic acid (5%) and water. The dielectric constant states how polar each solvent is, showing whether or not it will have a better reaction with the inks tested. The measurement of the solute and the solvent is calculated in this equation: The Rf value (retention value) is the distance at which the solute has travelled (Mobile phase). This is a useful technique as it can determine the polarities of the solvents. Determining whether the solvents are polar or non-polar is through their chemical structure and electronegativity charges. Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons. (Clark, 2000) Firstly, if the electronegativity difference is greater than 0.5, then it is considered as a polar bond and if it below...

...Maria Vasilenko 223901 Feasibility of using biosensors for heavy metal detection in complex matrices such as bio-slurries. Master of Science Thesis Examiners: Professor Matti Karp Professor Raghida Lepistö Examiner and topic approved in The Science and Bioengineering Department Council meeting on 7.11.2012 Abstract TAMPERE UNIVERSITY OF TECHNOLOGY Master‟s Degree Programme in Science and Bioengineering Vasilenko Maria: Feasibility of using biosensors for heavy metal detection in complex matrices such as bio-slurries. Seminar paper, 97 pages November 2012 Major: Biotechnology Examiners: Matti Karp, Raghida Lepisto Keywords: environmental pollution, heavy metals, biosensors, slurries The quality of bioslurries that are used in industrial production and agriculture need to be watched very closely to avoid spreading of contaminants on area and poisoning of humans and animals. Because heavy metals are very stable and toxic in many chemical compositions, their amount should be estimated very thoroughly. A new approach that involved biosensors was tested in this study. Because the slurries are complex non-unified matrices which composed of two phases – solid and liquid, the cell behavior can varies a lot from the one that explained in water and so the estimation of ion concentration can be not reliable. It was shown that the cell actually behave different in the slurries. Normally the dissolved compounds suppress the biosensor activity and, in the same time, the ions in the...

...AccuData® GTS/GTS The Advantage test strip contains the enzyme glucose dehydrogenase which converts the glucose in a blood sample to gluconolactone. This reaction liberates an electron that reacts with a mediator. The oxidized form of the mediator hexacyanoferrate (III) accepts the electron, forming the reduced form of the mediator, hexacyanoferrate (II). The Advantage test strip employs the electrochemical principle of biamperometry. The monitor applies a voltage between two identical electrodes, which causes the reduced mediator formed during the incubation period to be reconverted to an oxidized mediator. This generates a small current that is read by the monitor. If controls do not fall within the acceptable range after one repeat 1 Do not report the patient results (this would be if the operatoris running controls for the purpose of checking the meter; otherwise, the QC lockout would not have allowed the patient to be tested prior to getting the controls in acceptable range). 2 Review the test policy and procedure. 3 To get a trade, take all of the reagents and supplies out of the drawer and take the entire GTS to the High Volume Lab of Chemistry, 5th floor McCullough Bldg. 4 If feasible for the testing site, the Nurse Manager/designee or Clinic Manager can authorize the borrowing of a GTS unit from another location. cont.
