Does a Measurement Result in a True Value? Limitations of Measurements Elizabeth Lechtholz-Zey & Marisa Loredo 10/5/15 CHEM 101-08 Purpose To determine the differences in precision and accuracy in weighing 10 mL of water using a 50 mL beaker, a 10 mL graduated cylinder, and a 50 mL buret. Data Temperature of water: 23.0ºC 100 mL beaker weight: 50.557 g # of additions of water to the 100 mL beaker * 50 mL beaker (±5 mL) * 10 mL graduated cylinder (±0.05 mL) * 50 mL buret…

Determination of Most Advantageous Sequestering Agent By: Kayla Jeeter and Ashley Driscoll Chemistry 112-508 Abstract The creation and execution of this project served to determine what material is a better sequestering agent of the polycyclic aromatic hydrocarbons (PAHs) that are found in Texas’ water. Charcoal is currently the most typical agent used to sequester PAHs. In this experiment, two different Bentonite clays (zeolites) were synthesized, one magnetized and one not, to determine if…

Differences between experiments and demonstrations: The goals of doing research in biochemistry and biotechnology, along with others, are to find the truth about natural and unnatural occurrences with the help of the laws of nature. It is very important to note that the goal of most research is to simply answer, “what is going on;” it is possible that this question may have one or more answers. In the case of an experiment, the scientist may not know the outcome of their experiments, although…

assessment of AKI. The speaker was very detailed about this topic, but I only had what I can recall. I decided to go to this session because it’s something new that I’ve on no occasion heard about, and it seem like the next big thing to CLS/MLS in laboratory to look forward to doing on the job in the future. Acute kidney injury is a syndrome that results of a decrease in the kidney to function properly or damage to the kidney for hours or days. The AKI is causes from the waste in the blood…

Rules and instructions in the laboratory. “Laboratory is place that uses unique rules and regulations for your own protection and also others protections. So it is a must to aware with that rules and obey them”.  Before you entering the Lab you must read the PRACTICAL AND ITS PROCEDURE.  Never work alone or without teachers supervision.  Understand the hazards and symbols. (u must aware of that)  Use proper safety protection before entering the lab (wear goggles for eyes,wear lab…

Laboratory Technicians or MLT’s “perform routine laboratory tests done in hematology, chemistry, immunohematology, microbiology, immunology and coagulation while maintaining instrument maintenance and quality control” (MLT Job Description). There is also no patient interaction in…

Analysis of the Luria-Nebraska Neuropsychological Test Battery: Revised Children's Version The Luria-Nebraska Neuropsychological Battery (LNNB) created by Charles Golden, based on the previous work of Russian neuropsychologist A.R. Luria, is a neuropsychological battery that was originally developed to evaluate and measure neuropsychological deficiencies, specifically, in the learning, experience, and cognitive skills of adults ages fifteen and older. Golden later revised his work to…

To begin the first part of the experiment, zeolite and magnetized zeolite had to be synthesized. First, it was necessary to set up a contraption to hold a thermometer in place. This was done using a split cork and a 3 prong clam on a ring stand. 50 mL of 3.0 M NaOH was then added to a 250 mL beaker with a magnetic stir bar placed inside. After placing the solution on the stir bar, 3.7560 g of (sodium aluminate) was added to the solution. The thermometer was also added to the solution, but it…

After putting each compound into the blended meal, then it was determined whether it contains organic or inorganic in it. The bacon ranch salad reacted negatively to the solutions. While also being tested on a well-plate and hot-plate, it still remained the same color. Therefore, the blended mixture does not contain any organic substances such as protein. We began our experiment by gathering our materials and began to test the change in the blended mixture by putting a small amount in well…
