The exercise will curb the mistakes that could predispose the patient to fatal physiological states. Furthermore, a spin cross-match testing should be done using automated systems that enable detection of incompatibility. Retyping donor and the red blood cells of the recipient may show the problem of the transfusion. Any discrepancy will give a suggestion if the mismatch or mix up of samples in the blood that is used in a transfusion. Acute hemolytic reactions may occur during transfusion process.…
Systematic Errors Systematic errors occur in experimental observations, and usually come from the measuring instruments used. The reasons why systematic errors can occur might be because there is something wrong with the instrument used to gather the data, or its data handling system may have issues. Another reason may be because the instrument used for gathering the data is wrongly used by the person collecting data. There are two types of systematic error when using instruments that have a linear response: - Offset/ zero setting error:…
Two ways this experiments data could be considered more reliable is that, there were many runs of the experiment done all with the same parameters and the results are an average of all of the groups’ data. Another reason would that each group could have done the experiment slightly differently and gotten a different result thus showing what changing a variable can do to change the results. One region of bias in this experiment would be that one of the antiseptics used was the Purell hand sanitizer, which is intended to be used on ones hands instead of the face, so it would work less effectively than intended. Two experimental errors our group could have made would be: The agar could have been broken thus preventing bacteria from growing in the gash made. Or our group could have transferred more bacteria to one of the quadrants and not equaled the amount of bacteria in the other quadrants of the Petri…
Introduction: For this lab, the two main topics are surface tension and pennies. Pennies are a part of the US currency, which holds a value of one cent. They were mostly made by copper until 1982 when the government realized the expenses of using copper; thus, the composition was changed to 97.5% zinc and 2.5% copper or copper plated zinc. It has a diameter of 19.05 mm and a thickness of 1.52 mm and is forged using four procedures: Blanking, Annealing, Upsetting, and Striking. The design of the penny holds two alternative sides (heads or tails) which has a picture of Abraham Lincoln engraved on one end and a variety of pictures engraved on the other end (usually the white house).…
Determining the Percentage Yield of a Chemical Reaction Question: What is the percentage yield of the reaction of sodium carbonate and calcium chloride dihydrate (the dihydrate must be included with the molar mass calculation)? Predictions: Predict the mass of sodium carbonate and calcium chloride dihydrate that will be required to produce 1.90 grams of calcium carbonate: Therefore, the predicted mass of sodium carbonate is 2.0 grams and the predicted mass of calcium chloride dihydrate is 2.8 grams. Materials: 2 Beakers (150 mL) Calcium chloride Sodium carbonate…
Lab 4: Osmotic regulation of cell volume The eukaryotic organism requires homeostasis to maintain daily activities and life. Zooming into smaller units to make up an organism, cells also require homeostasis in order for the organisms to function. Understanding the different balance cells need to maintain will aid us in understanding how cells in organisms successfully maintain osmo-regulations. Eukaryotic cells have selective permeable membrane giving them the unique function of regulating specific molecules between the intracellular and extracellular environment.…
Identify possible sources of error in this lab. Walking is not the best method to calculate VO2 max as it is a submaximal test. There could be a miscalculation regarding your heart beat or the VO2 max equation. 3. Assess the practicality of using this lab in the field.…
To compare the two sets of watersheds (Wild River/Little Androscoggin River and Ellis River/Nezinscot River) hydrographs were created for the period of record, the 2010 and 2015 Water years for each tributary, as well as, comparing all four and each set. In addition to the hydrographs, the Richards-Bakers Flashiness Index was calculated for each tributary for the period of record, the 2010 and 2015 Water years; Flow-Duration Curves were also created for each tributary for the period of record, the 2010 and 2015 Water years.…
The article, Mass Transport in an Anatomically Realistic Human Right Coronary Artery, written by M.R Kaazempur-Mofrad and C.R. Ethier, analyzes mass transport patterns in a realistic right coronary artery model and looks at what affects mass transport from blood to the wall of the artery. The researchers were looking for any relationships between atherosclerosis, a disease of the arteries characterized by built up plaque on their inner walls, and hemodynamic and mass transport patterns. To begin, a model of the right coronary artery of a forty-seven year old woman, who did not die from cardiovascular related causes, was constructed. After making their assumptions, stated later on, boundary conditions were set for mass transfer and flow.…
Intracranial hematoma Overview: An intracerebral hemorrhage (ICH) happens when blood all of a sudden blasts into brain tissue, bringing on harm to the brain, which may show indications like that of a stroke. Lobar intracerebral hemorrhages happen in the cerebral projections outside of the basal ganglia. The basal ganglia are a structure situated in the cerebrum (the biggest piece of the brain) that guides in engine control, procedural learning, eye development, and intellectual capacity. Stroke-like manifestations generally show up all of a sudden amid ICH, creating side effects that incorporate cerebral pain, shortcoming, disarray, and loss of motion, especially on one side of the body.…
The research used for this study was Quasi experimental, one group design, since true experiment use comparison between two groups, controlled and intervention. The data collected for this study, fit with the research finding between the two drops of blood used and the hypothesis which proved that there were no differences between two drops of blood. Although Quasi is level III intervention was not require, this study was, furthermore, used for comparison, there were no pre/posttest.…
h Lab Report Katelyn Gularski (Hayly Stein) PM Tuesday 9/9/14 Introduction The purpose of this lab was to separate the mixture of salt, sand, and shells, so that each could be individually massed and the percentage-by-mass could be determined. The best way to get the sand and shells by themselves is to get rid of the salt. Since salt is dissolvable in water, you use water solubility (Hallows, 2014). Water solubility is defined as a substance being able to completely dissolve in water (“Water Soluble”).…
Blood Spatter: Low-velocity blood spatter would be any pattern is produced due to gravity being the only acting force (Gaensslen, Harris, & Lee, 2008, pg. 88). Medium-Velocity Blood spatter is where moderate force is applied from objects which can cause pooled blood to scatter in multiple directions surrounding the contact (Gaensslen, Harris, & Lee, 2008, pg. 89). “High-velocity blood spatter is the where extreme force acting on the blood source (Gaensslen, Harris, & Lee, 2008, pg. 89)." Blood Spatter is used in crime scenes to help in multiple ways. One way that that blood spatter can help is to help identify the object used based on the pattern of the spatter.…
As you might notice from my title, I have decided to place my interest on two different readings; The Good Man and Still I Rise. Both of these reading are wonderful pieces that spark my interest and exert the qualities from Marywood’s core values. The readings are extremely similar and different. The both show Empowerment, Excellence, and show a great deal of respect, but they show all of those qualities in different ways.…
What is the effect of increasing amounts of apple cider vinegar on the mass of milk curds? Purpose The purpose of the experiment conducted was to observe the effects of increased amounts of acid on the mass of yielded milk curds. Background Information Curd formation, or coagulation, is the process in which milk the proteins in milk clump together in the presence of an acid.…
