Geology Volcanoes&Earthquake Assignment8 Assignment

Geology Volcanoes&Earthquake Assignment8 - Assignment Example An inevitable tide was moving red-hot lava onshore and people watched helplessly. However, a small crew led by Thorbjorn Sigurgeirsson squirted the lava in the front with fire hoses producing vapors of steam (John A. McPhee. 102). The courageously watered and cooled the advancing lava until they stopped the lava flow (John A. McPhee. 107) The gas content in magma or lava determines whether a volcanic eruption will be explosive or effusive. These gases include sulfur dioxide, water vapor and carbon dioxide. A gas highly dissolves in magma that is situated deep underground, where pressure is very high. The rate of dissolution decreases as the lava moves up to the earth’s surface due to reducing pressure, thus, the gas form bubbles that drag magma to the surface. The eruption is explosive if more bubbles form and effusive when there are few bubbles. A cinder cone forms when lava with more bubbles is expelled and cools in the air (Gates and Ritchie p.157). Magma comprises of solid minerals, liquid rocks and gas. The amount of the silica mineral in lava or magma determines a volcanic rock to be formed. The mafic rocks include all basalts and some andesites: have lower silica content, intermediate rocks such as some dacites and most andesites with intermediate silica content, and silicic rocks. Silicic rocks have higher silica content and include all rhyolites and some dacites. Apart from silica, volcanic rocks have other minerals such as titanium, aluminum, iron, manganese, magnesium, calcium, sodium, potassium, and phosphorus. These chemicals are mix with oxygen to form their respective chemical compounds (Park, 2001, p. p.177). A magma viscosity determines a volcano shape, texture and shape of lava, and whether a volcano erupts effusively or explosively. A less viscous lava forms shield volcanoes with wide sloping sides while more viscous lava builds conical volcanoes with steep sides.

Innovation - Essay Example on X or Y worker; cafeterias, flexible working schedules as well as the 20% policy which allows each employee to make use of one day every week researching on a unique and innovative project of their own liking. Very few companies can afford such luxuries on their employees. Secondly, Google has built a product innovation culture. Thus numerous new products as well as services can be found from Google at present and engineers are persuaded to constantly create new ones. Google creates its own internal human resource together with talent management system, created on the conviction that Google can go on and do it â€Å"better.†Something that few organizations can afford to do (Carter & Ulrich, 2005). Some of Google’s products have gone on to become market leaders such as Google maps, Google Finance as well as Gmail which all penetrated the market with strong deep-rooted competition. Thus through strong execution and innovation every one of these products has taken on a remarkable market share in a very short length of time. Additionally when the corporation notices an incredible opportunity to penetrate via acquisition, it wastes no time and thus takes the plunge (Blogger and YouTube).Clearly Google’s long term victory is dependent on its ability to create a learning culture that embraces change, admits mistakes honestly, makes heavy investments in the winners and innovates continuously.

Discuss the claim that some areas of knowledge are discovered and Essay

Discuss the claim that some areas of knowledge are discovered and others are invented - Essay Example Discoveries have led to the development of the various disciplines in the educational systems today. Facts have been unleashed for every one to observe and use the knowledge to be efficient in the day to day operations (Maddox 1998 p 71). Both the knowledge acquired through invention and that acquired through discovery are significant for the advancement and sustainability of humans. This essay is a critique of the two kinds of knowledge. It presents the distinction as well as the relationships that exist between discovered and invented knowledge. The discovered knowledge helps people to predict the outcome of their actions. For example, the law of gravity that was discovered by Sir Isaac Newton helps people to understand why things always fall after being tossed away from the earth (Berlinski 2002 p 76). Such kind of discovered knowledge is amongst the fundamentals of a course such as physics. Other people who have discovered important knowledge include scientists Boyle and Charles who contributed to the discovery of gas laws and Michael Faraday who made several discoveries in physics amongst others (Donald 2005 p 57). In essence, these people did not change anything on what they discovered. What they did is just realizing how things work. On the other hand, inventions are usually accomplished after studying and understanding how things work. It leads to the development of theories that help people to work better. Many inventions can be combined to develop a complex unit, which is the basis for industrialization, medicine and other professions. For example, inventions of the alternating current theories by Steinmetz led to the development of electrical power generation; the law of electromagnetic induction invented by Michael Faraday was useful in developing the coils used in transformers and coils; invention of the integrated circuit by Jack Kilby was useful in development of electronic equipments that use electricity, and many other theories that

Hypovolemic shock and blood transfusion intervention Essay

Hypovolemic shock and blood transfusion intervention - Essay Example This research presented typical features of hypovolaemic shock, primarily developing from chronic alcoholism. The patient earlier episodes of epigastric pain and upper GI bleeds and was treated for the same by antiemetic drugs and antacids. Following that episode he was advised against drinking and smoking. In this event, Mr. Z developed nausea 48 hours before the haemetemesis. During the haemetemesis episode he vomited blood 5 times, containing blood coffee brown in colour and from the upper GI. In this case, the rationale for giving blood was that the patient’s haemoglobin levels were only slightly above normal, the blood loss was severe, and the patient’s condition was perceived to be serious. The physicians in this case had to make a close decision, as if the symptoms and the vital sign (especially blood pressure) could be managed effectively, blood transfusion was not needed. The criteria for blood transfusion are made based on general criteria and not the manageme nt or care setting for the particular patient. For example, if the patient is managed in the ICU, there is oxygen and respiration is taken care of and hence, anaemia may not be a serious issue that the patient has to cope with. Hence, the care settings have an important role to play. The most important criteria for transfusing blood for an ICU patient are whether the patient is hemodynamically stable or not. If the patient cannot be maintained properly in a hemodynamic state (even though the blood loss was minimum), then blood transfusion is needed. Haemoglobin is critical in ensuring oxygen supply to the vital organs and the tissues of the body. However, if the patient can be maintained hemodynamically stable (even though the blood loss was severe) and the haemoglobin levels is below 7 g/dl, the vital signs are seriously affected, then the patient has to be suggested for blood transfusion. In this case, it would be likely that blood transfusion was given as a precautionary measure although in the current care settings, stability of the vital signs and haemoglobin level it would not be necessary. Besides, the fact that the patient was currently in the ICU was not taken into consideration, and it is important that this fact be taken into consideration. The blood pack has been administered slowly over 3 hour duration (as per the mentioned in the case), and any risk of adverse effects were monitored. Though no urticaria and erythema were noticed, there has been a slight improvement in the patient’s blood pressure levels, APTT, Haemoglobin levels, heart rate and respiratory rate. However, there is not much improvement in other important components such as blood pressure, pulse, breathes rate and haemoglobin (Veenema, 2007). Ethically and legally, consent was obtained orally and carefully documented. The patient should be competent to give consent and only if the patient’s condition is such he is in a position to give consent, should consent be taken. There was also a need to ensure

Select 3 Decision Making Tools Studied in the Managing Decisions Essay

Select 3 Decision Making Tools Studied in the Managing Decisions Module and Evaluate their Advantages and Disadvantages - Essay Example Individuals as well as groups make decisions as a reaction to a problem in most cases. Robbins (1993) concurs with this assertion when he states that decision making takes place when there is a discrepancy between some current state of affairs and some desired state requiring consideration of alternative courses of action. Decision making is one of the primary responsibilities of all the employees given that they are somehow affected by the decisions made in the organisation. There are various tools or methods that can be implemented in carrying out the decision making process. Against this background, this report seeks to critically evaluate the approach of decision making through focusing on three methods that can be used in decision making and these include the following: project management, knowledge management as well as delegation management The report will outline the advantages and disadvantages of each decision making tool mentioned above and the third part will focus on how these methods can be combined in order to improve decision making in business. 1.1 Outline of the business opportunity Blue Tavern is an established bar but has recently experienced a decline in profits mainly as a result of lack of coordination among the employees which has resulted in some customers leaving without served. However, the management has underscored to implement a decision implement a new information system in a bid to turn around the fortunes of the company. As such, this report seeks to reflect on the benefits and limitations of the approach used in developing this business opportunity. As going to be shown in the following sections, a critique of the effectiveness of the decision making methods mentioned above will be carried. 2.0 Project management The term project is used to describe a set of linked activities which can be described as a onetime activity with a well defined set of desired results (Burke, 2007). A project is usually comprised of a definite start as well as finishing time and goes according to schedule. Project management plays a pivotal role in order for any project to be a success and it involves the following factors that often affect the full implementation of a project: scheduling, budgeting, communication and estimating. Essentially, the purpose of project management is to provide management with valid data upon which management decisions can be based (http://www.pim.com.pk/faq.htm). A holistic approach is required in order for a project as the one outlined above to be a success given that there are negative implications likely to be encountered during the course of implementing the project. Project management is often seen as a viable method of making decisions which often affect different projects. However, this method may have its shortcomings hence the following section is going to critically eva

Why did the U.S. government target Hiroshima and Nagasaki in 1945 Research Paper

Why did the U.S. government target Hiroshima and Nagasaki in 1945 - Research Paper Example Why did the United States choose to bomb Japan, and what factors led to the targeting of these particular cities, and the consequential high loss of human life? One argument for this use of deadly force is that the United States wanted to end the war with Japan quickly, before the planned invasion which was to occur a few months later. The bombs acted as a show of strength, as well as devastating the resources of the cities that were targeting and dealing a severe blow to the morale of the Japanese people. Understanding the factors that influenced the nuclear attacks on Hiroshima and Nagasaki is important, as the world is currently in a nuclear age, where many countries have nuclear capability but other countries do not. Additionally, understanding the behavior of the United States, and what influenced the decisions that occurred during this period is crucial, as the United States currently exists as the primary world superpower. This essay discusses the factors that drove the United States to use nuclear weapons on Hiroshima and Nagasaki, with the focus that these attacks were focused on the nuclear weapons in Japan, rather than the citizens. How are nuclear weapons currently perceived? Nuclear weapons are extremely powerful, and have the ability to decimate cities, destroying buildings and killing people with no prior warning and no method of defense (Krieger 2003, 3) The devastation that occurred from Hiroshima and Nagasaki
