I am taking a chemistry class and we have been asked to write a chemistry paper for the final assignment. When I started thinking about a topic the wheels started to turn. I than found myself asking the question, what is chemistry exactly? Chemistry is the scientific study of interactions of a chemical substance that are constituted of atoms or the subatomic particles that include protons, electrons, and neutrons. Atoms combine the produce molecules or crystals. Chemistry is often called "the central science" because it connects the other natural sciences such as astronomy, physics, material science, biology, and geology. The genesis of chemistry can be traced to certain practices, known as alchemy, which had been practiced for several millennia in various parts of the world.
Then I wonder that a chemical reaction is. A chemical reaction is a transformation of some substances into one or more other substances. It can be symbolically depicted through a chemical equation. The number of atoms on the left and the right in the equation for a chemical transformation is most often equal. The nature of chemical reactions is that a substance may undergo the energy changes that may accompany it are constrained by certain basic rules, known as chemical laws.
So what is a chemical law? Chemical laws are those laws of nature relevant to chemistry. The most fundamental concept in chemistry is the law of conservation of mass, which states that there is no detectable change in the quantity of matter during an ordinary chemical reaction. Modern physics have shown that it is actually energy that is conserved, and that energy and mass are related; a concept which becomes important in nuclear chemistry. Conservation of energy leads to the important concepts of equilibrium, thermodynamics, and kinetics. So now with all that said; I can get to the real question that has been bugging…...

X-Ray Tube Function

...Since an x-ray tube requires a direct current, some sort of means is required to change from AC to DC. With this x-ray tube it uses a single phase unrectified power source. Rectification is essential for safe and efficient operation of an x-ray tube. Since it is a single phase it will end up having a pulsating x-ray beam. This is caused by the alternating swing in voltage from 0 to 120 times each second under full wave rectification. A disadvantage of a single phase power source is that the x-rays created from single-phase voltage have a value close to zero and are of little diagnostic value due to their low penetrability. * single-phase generators produce voltage that varies from 0 to its maximum value With a metal enclosure the tube is able to maintain its constant electric potential between the electrons of the tube current and the enclosure. Some of the benefits of a metal tube are that it will have a longer life and is less likely to fail. With a metal enclosure you eliminate the problem of tungsten vaporization through grounding of the metal enclosure. The rotating anode which is usually made of molybdenum due to its poor thermal conduction allows the electron beam to interact with a larger target area; therefore, the heating of the anode is not confined to a small spot like with stationary anodes. The heat capacity can be improved by increasing the speed the anode is rotating at. A rotating anode is used in units that produce high-intensity beams and......

Magic Youth Serum

...Tiffany Gabbard 18 September 2013 English 101 Advertisement Essay Magic Youth Serum “How do I want to look seven even busier years, two teenagers, and eight college applications from today?” This is the question that Olay Total Effects, uses in their advertisement for their Seven-In-One Moisturizer Plus Serum Duo to imply that family, time and stress cause aging to accelerate. The ad answers its own question with, “Not one day older than I do now” creating an aura of a magic serum that stops signs of aging in its tracks, even though we all know that is impossible. The words “old” and “ugly” are synonymous when a woman thinks of aging. Women lie about their age for this exact reason, so the beauty industry markets anti-aging wrinkle creams that claim to help women stay youthful and beautiful. A close up photo of a beautiful blonde woman’s face covers almost the entire page of this advertisement. The model has very minimal makeup and almost flawless skin, aside from a few small wrinkles underneath her eyes. Her expression is confident with a slight knowing smile as if she has found the secret formula all women have been desperately searching for. At the bottom center of the page there is a small bottle of the anti-aging moisturizer surrounded by two fluids spiraling around it like a tornado. Each fluid is a different color, one white, and the other is light beige. The bottle itself is beige with the product label featuring a large golden number seven. Overall, compared......

Human Serum Albumin

...BCHM456 HUMAN SERUM ALBUMIN (1E78) The Structure and Significance of Human Serum Albumin in Blood MJ May 11, 2013 Abstract Human Serum Albumin (H.S. Albumin) is the most common transporting protein found in blood plasma. Its Y-shaped molecule is mostly build of α-helix configurations that are perfect sites for carrying hydrophobic organic compounds. The human organism highly depends on the proper functioning of H. S. Albumin, thus its function and nature have been extensively studied. This article briefly describes H. S. Albumin structural features and how they influence albumin’s transposing mechanism. Introduction Proteins are large polypeptide molecules consisting of chains of amino acids. The order of amino acids in each protein is determined by the codon of the nucleotide acid sequence that is encoded within the organism’s genetic material. The combination of amino acid sequence influences how the protein will fold into its specific, three-dimensional structure. In turn, the protein’s three-dimensional structure will highly influence the physical and chemical activity of that protein. Proteins perform all major functions within living organisms. One of these functions is transportation of molecules from one location to another. Human serum albumin is a common protein in human blood responsible for transporting metabolite products, lipids and drugs. Human serum albumin makes......

The Feeding Tube

...The Feeding Tube 1. Explain how the Patient Bill of Rights applies to this situation. The patients of the country in the United States are provided a particular right. This right is called the Patient Bill of Rights (Kronenfeld, 2002). The Patient Bill of Rights has a significant impact and is essential for the people who are in the health care organization for the purpose of getting treatment properly and easily. In this scenario, June is suffering from anorexia and the doctors feel she may need to be placed on a feeding tube to save her life. June agreed to the procedure but became combative, disoriented and refused to have the tube place the evening before the procedure was to take place. The patient bill of rights applies, as the patient has a right to know what treatment options are available to one and what the possible outcomes may be. The patient has a right to decide one’s medical care. One also has a right to know of any side effects of treatments. June needs to be told what may happen without the feeding tube and what can be expected with the feeding tube. June also has a right to have her health information kept confidential, with information given only to those she designates as being allowed to have her health information (Showalter, 2008). It is noted that in the absence of a progressive terminal disease, the feeding tube may be used to prolong life and since the patient is not dying of another cause, discontinuing the feeding tube would imply a desire to......

Tube Feeding

...concerning his treatment or designate a surrogate decision maker with the expectation that the hospital will honor the intent of such directive to the extent permitted by the law and hospital policy (Fermgen 2009). In this scenario the bill of rights that is applicable, is that the patient has active rights to know and take part in the treatment decisions in which Ms June has done from the beginning which made her consent to the insertion of the tube into her. In other words she also has the right to refuse treatment as result of being combative and disoriented, in which the hospital should honor her opinion, because it was not stated in this case that she has signed an advance directive or given somebody a power of attorney to act on her behalf. It should be noted that her case should treated due care and adhering to the patient’s bill of rights which is a set standards for providers and also for patients. In conclusion this case should be treated with care and diligence, because if the medical provider makes the moves to inserting tube this could be violation of patient bill of rights which in turn could result in a big law suit against the hospital and the physician. In other words in this scenario the patient case is an emergency situation, where the physician might not liable for violation of bill of rights because it is an emergency situation to save her life....

...The Feeding Tube Class HSA 515 Assignment 4: The Feeding Tube Write a 4 to 6 page paper based on your answers to the corresponding questions for the following scenario: Scenario: June, a 34-year-old divorced woman diagnosed with severe anorexia, is hospitalized. Her doctors feel she may need to be placed on a feeding tube soon to save her life. Initially June agreed to the feeding tube. However, in the evening (before the tube has been placed), she became combative, disoriented, and refused to have the feeding tube placed. Her mother and father insisted that the feeding tube be inserted despite her refusal to allow it. Her ex-husband wishes to uphold June’s decision. The hospital administrators seek risk management for legal counsel. Utilize your Showalter textbook and at least two other sources to answer the following questions: 1. Explain how the Patient Bill of Rights applies to this situation. The U.S constitution is called the supreme law of the land because it sets standards against which all other laws are judged. The constitution is a grant of power from the states to the federal government. The constitution is a grant of power from the states to the federal government.

Vaccume Tubes Research Paper

...VACUUM TUBES A Research Paper Presented to the Faculty of School of Engineering Asia Pacific College Magallanes, Makati by Pamela Joyce M. Espigol In Partial Fulfillment Of the Requirements in Electronic Devices and Circuits Lec Date Submitted October 30, 2015 II. INTRODUCTION a. RESEARCH PAPER SUMMARY NO. | ABSTRACT | METHODOLOGY | RESULTS | CONCLUSION | RECOMMENDATION | 1 | The objective of this work is to simulate a tube guitar amplifier, the Giannini True Reverber designed by Carlos Alberto Lopes in the nineteen sixties. The nonlinear “overdrive” characteristics of these devices make them attractive for guitarists since odd harmonics are added into the guitar sound as well as sound compression. The shortcomings of these amplifiers led to the development of DSP simulation techniques over the last few years. Many past DSP simulations of tube amplifiers were implemented using Static Digital Wave shappers for the task of replicating the tube transfer characteristics. Since the physical behavior of such systems is quite complex, physically informed models are necessary for more precision in the simulation, requiring more computer power. A Wave Digital Filter (WDF) simulation of the Giannini True Reverber double 12AX7 preamp is accomplished in this work using Koren’s triode equations and Block Compiler, where each parameter was acquired in the original electronic schematic or by measurement of the real amplifier. The real preamp is compared to the...

Drainage Tubes

...There are many chest drainage systems but the most traditional is underwater seal chest drainage system. This system is a device that is attached to long hollow plastic tube that is inserted in the the chest wall between the ribs and pleural space. The purpose of this system is to allow blood,fluids,pus or air to be drained from the intrathoracic space. In doing so this allows the lung to re-inflate by restoring negative pressure. underwater seal chest Drainage system is commonly used in the treatment of pneumothorax, pleural effusion, and empyema. An underwater seal drainage system typically has four components the drainage chamber, the water seal chamber ,the suction control chamber and the positive pressure valve. The first chamber is the drainage chamber, this chamber is where the drainage from the chest is collected. The second chamber is the the water seal chamber, this chamber allows air to leave the chest and not renter.Tidaling may be seen which is fluctuation of sterile water in the chamber secondary to inhalation and exhalation. Gently bubbling may be seen in this chamber if the patient coughs or exhales. Continually bubbling in this chamber is indicative of a system and all tubing from Client to device should be checked. The third chamber is the suction control chamber the height of the sterile water in this chamber will determine the amount of negative pressure that is applied. The higher the sterile water volume, more suction will be produced. To much......

Tube Feeding Prolonging Life

...Abstract This paper is written to discuss the ethical dilemma we come across when asking our self whether or not we should place a tube feeding in a patient with a history Alzheimer’s or Dementia. Will this prolong the patients’ life or just the inevitable death? Most often a decision needs to be made regarding the placement of a tube feeding. The question is not initiated by the patient themselves. This is the reason why educating our patients are so important. In this paper I will discuss how important the role of the healthcare professional plays in advocating for a patient. To help answer this ethical dilemma several issues will be explored. I will focus on the seven principles of ethics, education, utilitarianism, top-down theory alternate treatment options. Will Tube Feedings Prolong Life? While working with the majority of geriatric population, we frequently come across patients with Dementia and Alzheimer’s disease. The most common problem in these patients is the inability to swallow as well as the patients are failure to thrive. Many healthcare workers and family members become upset when the patient does not have proper nutritional intake. As human beings it is our nature to take care of our loved ones when they are ill, this is our ways of showing love and affection tore’s each other. We often question the situation regarding the need for artificial feeding. Care givers have misconceptions if we provide artificial nutrition it will help......

Pressure Distribution in a Venturi Tube

...A VENTURI TUBE The graph below shows the comparison between the measured static pressure and the theoretical static pressure. From the graph, it can be seen that the measured static pressure was greater than the theoretical static pressure from tapping points n=1 to n=4 after which it is less than the theoretical static pressure after n=4 to n=11. There is a great pressure drop from n=1 to n=4 for both the measured static pressure (1850-421) and the theoretical static pressure (1850-338). This is because of the rapid change in diameter from 26mm at n=1 to 16mm at n=4. The decrease in diameter causes the velocity to increase and the pressure energy is converted to kinetic energy so that the volume flow rate is consistent. After n=4, the pressure increases gradually to approximately where it was initially. This is because of a gradual increase in diameter from 16mm at n=4 back to 26mm at n=11. This causes the velocity to decrease and the kinetic energy is converted back to pressure energy to maintain the volume flow rate. However the results are not very accurate due to errors in the experiment, one of which could be the parallax error as the pressure levels may not have been read accurately at eye level. The difference may have also been caused by a rounding error as the exact calculator values were not taken, just the rounded off ones. This is however negligible in relation to other errors. As for the value of the Discharge Coefficient, Cv of the venture tube, it was......
