LOGISTIC MANAGEMENT 3 - Essay Example Firstly, companies examine the flow of value throughout the production down to the customer. Then they classify the processes that need improvement by using nonperforming functional metrics. Additionally, they use other elements of the model like the fishbone structure to explain the cause and influence of the people, resources, systems, equipments and the environment on the improvement of their products and services (Cole, 2011). With this knowledge, companies hence focus on costs reduction by optimizing their processes while controlling the production inputs to eliminate defects. Additionally, they focus on error reduction by strengthening and automating procedures for completing the production. Lastly, management of the model entails frequent inspections and auditing to ensure that the scheme maintains high performances (Cole, 2011). JIT concept facilitates the LSS management scheme by helping the company minimize their in-process inventories. JIT provides a cycle of signals, which informs the production line hence the system is able to identify the appropriate time of initiating each specific stage of production (Cole, 2011). The model uses ordinary indicators mainly the visual signals like the deficiency or presence of a piece that is essential for the production

Response to an article on alcoholism Essay Example | Topics and Well Written Essays - 1000 words

Response to an article on alcoholism - Essay Example Dowshen (2009) suggests that alcohol acts as a depressant because it slows down the functioning of the central nervous system by obstructing or blocking messages that are communicated to the brain. This blockage has the effect of altering perceptions, emotions, and vision, movement and hearing abilities of an individual. Although Dowshen argues that alcohol when taken in small quantities helps a person to have a feeling of relaxation and less anxiety, when taken in huge amounts it causes big changes in the brain that results in intoxification. This is whereby a person, who has over consumed alcohol staggers, loses coordination and is slur in speech with a probability of being confused and disoriented. The person might think that they are okay but they may not be because they might be slow in reaction and out of their character. In addition, when alcohol is consumed in a short period in huge amounts, it can result to poisoning commonly referred to as alcohol poisoning. In this stage, the body is poisoned by alcohol such that it is induced to vomit, sleepiness, breathing difficulties, low blood sugar, seizures and unconsciousness. Zieve et al describes alcoholism as when an individual has or shows â€Å"signs of physical addiction to alcohol and continues to drink despite physical and mental health threats and social problems or job responsibilities† (2). Research worldwide indicates that alcoholism is the most prevalent psychiatric disorder in the society today. Alcohol addiction therefore occurs when a person’s body becomes dependent on alcohol and the body builds tolerance to alcohol, which results, to the person taking a larger dose of alcohol than before, to get the same effect. A person who is addicted to alcohol is therefore referred to as an alcoholic and therefore, alcoholism is the disease of alcohol addiction and it is chronic. The article

Motion of the Earth :: physics earth spin

The Earth spins around an axis. The Earth takes (a bit more than) one day to go around once. This axis is pointing off somewhere in space. This axis (mostly) doesn’t move. At the same time, the Earth is orbiting the Sun. It takes (a bit more than) one year to go around once. The plane of the Earth’s orbit (mostly) doesn’t move. The spin axis of the Earth’s daily rotation is not perpendicular to the plane of the Earth’s orbit.It is tilted (approximately) 23.4 degrees. The angle of tilt (mostly) doesn’t change. Earth does not spin perpendicular to the plane it is tilted, the reason earth is tilted is because it got hit by meteoroids and other stuff when the planets first formed. Also it takes about 24 hours for one period of earth rotate. From that we get sunlight, half of our days. We can calculate easily how fast earth is spinning by 2πR(radius of the earth)/24 hours. but that is just speed of the equator of the earth. We have different spinning speed every different latitude. As we could see from above picture every latitude have different speed of spinning per hour. And speed of the earth spinning could effect on such as water reservoirs.We don't feel that because everything else is moving with us and because the motion is very, very smooth. Changes in the Earth's spin are measured in terms of length of days. A faster spin shortens the length of daylight. "Due to the reservoir effect," (Chao). "the day 40 years ago was longer than today by about 8 millionths of a second." More significant, he said, is the fact that the sporadic spacing of water reservoirs has changed the Earth's axis. Since 1940, water impoundment has pushed the axis of rotation about 60 centimeters away from the North Pole toward western Canada, said by Chao Also it effect on the direction of the wind and movement of the clouds. "Stars and planets form as a result of the gravitational collapse of accreting material. Any net translational motion of that initial material is accelerated as its radius of rotation decreases. Once an initial spin was established for the Earth, the same conservation principle says that its angular momentum will continue unless it can be transferred to another object. With no significant frictional forces to allow that to happen, the Earth can continue to spin indefinitely without any further prodding" said by Paul Walorski.

Discover the affects of PH on the enzyme catalase

Catalase- This is an enzyme found in food such as potato and liver. It is used for removing Hydrogen Peroxide from cells. Hydrogen Peroxide is the poisonous by-product of metabolism. It speeds up the decomposition of hydrogen Peroxide into oxygen and water. It is able to do this because the shape of its active site matches the shape of Hydrogen Peroxide molecule. This type of reaction where a molecule is broken down into smaller pieces is an ANABOLIC REACTION. BACKGROUND INFORMATION ON ENZYMES: Enzymes- Enzymes are complex 3-D globular proteins, some of which have other associated molecules. Enzymes are a catalyst which alters the rate of chemical reaction without itself undergoing a permanent change, and therefore can be used over and over again. Enzymes help reactions speed up which would otherwise take place very slowly. While the enzyme molecule is relatively larger than the larger than the substrate molecule it acts upon, only a small part of the enzyme molecule actually comes into contact. This region is called the ACTIVE SITE. The active site of an enzyme is the region that binds the substrate and contributes the amino acid residues that directly participate in the making and breaking of chemical bonds. However, all enzymes operate only on a specific shape and therefore fit only complementary locks, so only substrates of a particular shape will fit the active site of an enzyme. Prediction I predict that as the PH increases the activity of enzyme increases until the optimum PH is reached. Catalase optimum ph is around 6-7.after that the enzyme will be denatured. Hypothesis The enzyme will have an optimum pH of around neutral. Either side of the optimum pH will have relatively high rates of reaction or far away from the optimum pH will have a low rate of reaction. The enzyme catalase is found in many tissues including potato and liver. It is important because it breaks down the hydrogen peroxide formed in metabolism. Hydrogen peroxide is toxic and if it were not broken down it would kill the cells. As it does this, it liberates carbon dioxide that can be collected. CHEMICAL EQUATION: 2H2O2 ——————-> 2H2O + O2 I also hypothesize that the catalase activity will be highest with the sample of potato comparing to the apple. Variables The factors, which will have an affect on the enzyme activity, will be: * Temperature * Concentration of enzymes * pH The variable in which I will be using to investigate the enzyme activity is the temperature. The rest of the variables will be kept constant and only the temperatures will be changed. Apparatus To test how the PH affects the rate of reaction, I will use the following apparatus: * Gas syringe through bung * Potato * Hydrogen Peroxide * Stop Clock * Cork borer * Scalpel * water Beaker-250 cmà ¯Ã‚ ¿Ã‚ ½ * Delivery Tube * Ph 3,5,7,9 * 5 cmà ¯Ã‚ ¿Ã‚ ½ or 10 cmà ¯Ã‚ ¿Ã‚ ½ plastic syringe with end cut off * measuring cylinder * conical flask * White tile * wax * Test tubes * Test tube rack * Safety equipment; goggles, lab coat, gloves Alternative: Use yeast, broad beans or liver, instead of potato and apple. Method 1. Measure out 5cm3 of potato into a conical flask 2. Measure out 10 cm3 of buffer solution into a separate container and mix it with minced potato. 3. Measure out 5cm3 volume of hydrogen peroxide in syringe. 4. Fill a tub with water. 5. Completely immerse a measuring cylinder in the water making sure to release all air bubbles in the cylinder and keep underwater. 6. Position the cylinder upright ensuring the open end remains underwater and clamp securely 7. Add the hydrogen peroxide to the potato and place bung on conical flask whilst starting timer. 8. Run experiment for 5 minutes taking readings every 30 seconds by noting the amount of gas at top of cylinder (at meniscus) 9. Repeat the experiment with different ph. Justification of method: I have chosen to use this method because it is safe, efficient and accurate. I feel that it will help me to obtain reliable results. Risk Assessment * Hydrogen peroxide is a dangerous substance. It can cause serious injury to the eyes and skin. It is therefore necessary that goggles be used for eye protection. In addition, eye irrigation equipment should be readily available in case of an emergency. * The working area must be clean, tidy and dry. Make sure there is no obstacle in the working area so that you can easily move around as. This allows you to perform the experiment safely and unimpeded care should be taken to ensure that liquid is not spilled onto the floor to cause slippage. Result table Time(s) Oxygen gas collected (cm3) Ph 3 ph 5 ph7 ph9 30 1.5 1.5 0.5 1.5 60 1.5 3.0 1.5 2.0 90 1.5 5.0 2.0 2.0 120 1.5 7.0 5.65 2.0 150 1.5 8.3 10.3 2.0 180 1.5 9.0 14.35 2.0 210 1.5 10.0 17.35 2.0 240 1.5 11.1 20.15 2.0 270 1.5 13.6 24.15 2.0 300 1.5 14.0 31.15 2.0 These results clarify that the optimum ph for catalase is 7 which supports my prediction. At the lowest ph 3, less oxygen was released, measuring a slower rate of reaction. My background information explains this. The enzyme don't work as it is neared extreme PHS. This is because its shape would have been change slightly; means the active site may not fit into the substrate any more. Further investigation: If this investigation were to be done again, I would take all results myself and use my own interpretation, thus gaining more reliable results. I will know how much potato to measure out for each experiment and also I will make sure that the other variables are kept constant. I have taken the same amount of each, keeping them constant. This would give me clearer results to aid me in my understanding as to how ph can affect the activity of catalase.

Difference Between Independent and Dependent Variables

The two main variables in an experiment are the independent and dependent variable. An independent variable is the variable that is changed or controlled in a scientific experiment to test the effects on the dependent variable. A dependent variable is the variable being tested and measured  in a scientific experiment. The dependent variable is dependent on the independent variable. As the experimenter changes the independent variable, the effect on the dependent variable is observed and recorded. Independent and Dependent Variable Example For example, a scientist wants to see if the brightness of light has any effect on a moth being attracted to the light. The brightness of the light  is controlled by the scientist. This would be the independent variable. How the moth reacts to the different light levels (distance to light source)  would be the dependent variable. How to Tell the Variables Apart The independent and dependent variables may be viewed in terms of cause and effect. If the independent variable is changed, then an effect is seen in the dependent variable. Remember, the values of both variables may change in an experiment and are recorded. The difference is that the value of the independent variable is controlled by the experimenter, while the value of the dependent variable only changes in response to the independent variable. Remembering Variables With DRYMIX When results are plotted in graphs, the convention is to use the independent variable as the x-axis and the dependent variable as the y-axis. The DRY MIX acronym can help keep the variables straight: D is the dependent variableR is the responding variableY is the axis on which the dependent or responding variable is graphed (the vertical axis) M is the manipulated variable or the one that is changed in an experimentI is the independent variableX is the axis on which the independent or manipulated variable is graphed (the horizontal axis) Independent vs Dependent Variable Key Takeaways The independent and dependent variables are the two key variables in a science experiment.The independent variable is the one the experimenter controls. The dependent variable is the variable that changes in response to the independent variable.The two variables may be related by cause and effect. If the independent variable changes, then the dependent variable is affected. Sources Carlson, Robert. A concrete introduction to real analysis. CRC Press, 2006. p.183.Dodge, Y.

Is Beowulf a Hero - 2129 Words

Is Beowulf a hero? It is vital when approaching the question of whether or not Beowulf can be viewed as a hero to attempt to understand the concept of a ‘hero. Joseph Campbell, the American theorist, studied mythological characters and texts in great detail and developed the concept of the monomyth (or Heros Journey) which he suggested all heroes undertook: A hero ventures forth from the world of common day into a region of supernatural wonder: fabulous forces are there encountered and a decisive victory is won: the hero comes back from this mysterious adventure with the power to bestow boons on his fellow men. If we are to take this statement as being accurate it is fair to say that at least in so far as what actually occurs in†¦show more content†¦Shortly before his contest with Grendels mother we are told he is ‘indifferent to death a point which is exemplified when prior to the fight he sets out his wishes to Hrothgar for what should be done should he perish. He is not arrogant enough to assume victory is assured and yet he is also courageous enough to not fear the possibility of defeat. In Seamus Heaneys translation of Beowulf we constantly see him referring to the great Geat as a hero. For instance ‘the hero arose and ‘heros helmet are but two of the references made. Although it is a hugely contentious issue, if we are to assume that Heaney is attempting, if only on the point of calling Beowulf a hero within the actual translated text, to give as direct a translation as is possible then it would seem apparent that the original author was making no secret of the fact he wanted him to be seen in this way too. There have been many criticisms of the character of Beowulf that highlight certain traits which could point away from the notion of him being a hero. One such idea is that he fought the monsters chiefly for personal reasons: ‘Beowulf steadily shifts from a primarily defensive role to an aggressive one, motivated to varying degrees in each of his battles by thoughts of glory, vengeance and treasure It is particularly the stance that Beowulf was motivated by thoughts of glory that I believe endangers the belief that he was a hero.Show MoreRelatedBeowulf Is A Hero Of Beowulf1017 Words   |  5 PagesIn the movie and book Beowulf, Beowulf represents a hero.
