  • Native American Mortuary Practices

    Americans are misrepresented in the history of mortuary practices. Native American embalming consisted of four ritualistic steps. First incisions are made length wise along only the back of the deceased body. The flesh is then removed from the body in one large piece. I have a unique insight into this process because I have been a part of it. A body came into the funeral home with a fatal shot from a small caliber round to the head. The interesting thing about small caliber injuries is that while the bullet enters the cranial cavity it often does not have enough force to leave the cavity. The bullet enters and bounces around inside of the head turning the brain to mush, and then coming to rest inside the head. This mush speeds up the decomposition process and also leaks out of the nasal cavities; therefore, it must be removed. There is a device called a trocar which is used to remove fluid from cavities. However, it is about two feet long with a circumference of three inches and much too large for the nose. In order to preserve the skin for an open casket visitation it had to be removed. I personally assisted in the defleshing of the face and head. I can attest that it is a painstakingly slow and methodical task to strip a humans skin off of their muscular system, remove a piece of the skull, remove the brain, and then sew the face back on so no one can tell. The process the Native Americans went through had to be incredibly time consuming and ritualistic. The second step was…

  • Lab Report: Redox Chemical Reactions

    involves the transfer of electrons between two reactants. These reactions were identified as a redox reaction because of how they turned into a different color, signifying there was a transfer of electrons which changed the physical appearance of the solution. In order for the reaction to be redox, a chemical substance has to be used up in the process and it has to create a new chemical substance. It also had to have a transfer of electrons between each other, if there is no transfer, then the…

  • Chemical Reactions Lab

    Chemical Reactions I Purpose The purpose of this experiment was to test and see how four different chemical reaction worked. The four different chemical reactions are formation, decomposition, single-replacement, and double-replacement. The hypothesis of this experiment was that in each of the different reactions something would happen to the reactant whether it be color, mass, temperature, or pressure. II Equipment For this experiment Late Nite lab was used. In Late Nite Lab the equipment…

  • Chemical Reactions

    Review 3: Text Chemical reaction is the changing of substances to other substances by the breaking of bonds in reactants and the formation of new bonds in products. There are many different types of reactions. Many reactions can be assigned to more than one classification. The same reaction can be classified in different ways. It is important and useful to know all the different types of reactions because they often refer the reactions as being of one type or another. The first reaction is…

    Feb). The more advanced methods overcoming drawbacks of the PP method when the modes are spaced closely are frequency domain decomposition method (FDD) (Brincker R, Zhang L, Andersen P (2001) Modal identification of output-only systems using frequency domain decomposition. Smart Mat Struct 10:441–445) or complex mode indication function method (CMIF) (Shih CY, Tsuei YG, Allemang RJ, Brown DL (1988) Complex mode indication function and its applications to spatial domain parameter estimation.…

  • Essay On Chemical Reactions

    Introduction: Chemical reactions are a process that involves, rearranging the molecular structure of substances to create new ones. There are 3 types of chemical reactions, firstly there's synthesis, (e.g. 2Na + Cl2 → 2NaCl); then, the other type of reaction is decomposition (CaCO3 → CaO + CO2); and finally there is combustion. Combustion is a rapid chemical combination of a substance (fuel) with oxygen, including the production of heat and light (e.g. CH4 + 2O2 → CO2 + 2H2O). In these types…

  • Chemical Reaction In Cooking Food

    Chemical Reaction A Chemical Reaction is when there is change from physical reaction to nuclear reaction. In chemical reaction, there is also a change of a chemical substance to another, which in that case is the change to one or more productions. It 's when a substance changes and when you combine chemicals or mix them, you 'll most likely create a new one, not always but most of the time it will. Cooking food always involves a chemical reaction. It could be from baking a cake by mixing the…

  • Enzyme Concentration Lab Report

    the rate of the chemical reaction. Furthermore, varying amounts of pH and enzymes were added to the mixture in order to determine the substance’s rate of reaction. When the reaction occurs, students are supposed to study and observe it until the substance becomes denatured. In this instance, the proteins are becoming denatured, which is the process of modifying the molecular structure of a protein. Proteins…

  • Green Chemistry Principle Lab Report

    The purpose of this lab was to perform each experiment correctly and according to the Green Chemistry Principles. There were four parts to this lab. The first part was to familiarize myself with the Bunsen Burner by sketching it out in my laboratory notebook. The next part was to look through Table 4.1 in the laboratory notebook to determine which experiments I was to perform. The last two parts included performing the reactions and writing the ionic and net ionic equations. Writing out the…
