  • The Aerospace Industry

    1.1 Overview of aerospace industry Globally, 3.57 billion passengers travelled on aeroplanes during 2015 and the demand for air travel is predicted to keep rising.1 As the frequency of air travel is increasing, it places a pressure on the aerospace industry to improve material performance and the efficiency of their transportation.2 Classically aircraft were constructed from metallic materials such as aluminium and titanium. Therefore, new materials must have specific properties and characteristics that the metallic materials possess, but in addition, present further beneficial properties. Aeronautical materials must possess a high Young’s modulus to prevent shape deformation under stress, high resistance to chemical and thermal degradation, high glass transition temperature (Tg), impact strength, amongst numerous others which are more task specific.3 Advancements in polymer chemistry have resulted in a large number of aircraft moving from metallic materials to composite for their primary structures. The definition of a composite states that it is a new material with superior structural properties, which is formed from two or more materials that differ in physical and mechanical behaviour. The superior structural properties are not present in the individual components from which the composite is constructed.4 High-performance composites used in the primary structures of aircraft are carbon fibre reinforced plastics (CFRP). CFRP’s are mainly used in high-tension loaded…

  • Difference Between Carrageenan And Vanillin

    clear complexes of helixes or entanglement may indicate the defect of the network and produced the exothermic peak in DSC result. A study on fabrication of nano fiber from alginate (Nie et al. (2008) found that the entanglement may increase the flexibility of chains of alginates. This flexibility may promote the swelling capability of the non-crosslink sample. The AFM analysis measured the average Young’s modulus of 2344.17 MPa for the non-crosslinked film and 2314 MPa for the crosslinked film…

  • Varsity Team Case Study

    different elements that are affecting the overall performance and commitment of the Varsity team. The Varsity crew has a large pressure to be the best in the program, because that is what they have been selected for; on the other hand, the Junior Varsity crew has “nothing to lose”. This affects both teams’ motivation, because the J.V team is intrinsically motivated through enjoyment of the sport. However, the Varsity team is extrinsically motivated, because it craves the praise associated with…

  • Superman To The Rescue Article Analysis

    In the article Superman to the Rescue: Simulating Physical Invulnerability Attenuates Exclusion-Related Interpersonal Biases (Ackerman, Bargh, & Huan, 2013) Julie Huan, Joshua Ackerman, and John Bargh set up a number of studies including a pre-test, study one, study two, and study three to demonstrate the relation between physical invulnerability simulation and positive or negative reactions to being excluded in social situations. They also consider how the reactions of exclusion can change when…

  • The Klamath River Basin

    Tarlock 2007). For nearly a century, clashes between fishers, tribes, environmentalists, and farmers have peaked and ebbed during water shortages and fortuitous wet years. The Euro-American colonial legacy and the settlement and occupation of native territories has resulted in the dispossession of indigenous lands and waters, as well as the strict regulation of indigenous access to waters formerly under their jurisdiction by American government forces (Most 2006). . The Klamath Hydroelectric…

  • The Influence Of Exclusion

    This article talks about how people react when they are/feel excluded. Certain people have different coping mechanisms for this and reasons why they are hurt by being excluded. The authors in this article go in depth as to what factors could lead people to having a lower sense of fear that people get from exclusion and the psychology behind it all. The main theory of this article basically acknowledges the fact that people are discomforted by rejection and exclusions. When people are excluded…

  • Broomfield Employee Performance

    Broomfield demonstrated that he is not very keen on the word “power”. He does not believe that power is something that is necessary when working with others because, as he said about fairness, everyone is equal with one another and work together as one. Broomfield referred to the popular phrase that the group is only as strong as their weakest link when talking about power and influence. However, he added that he is not ambitious about the weakest link because that reveals that the top, or the…

  • Summary Of The Goal

    plant and his goal. Alex was forced to work through a scientific equation to find the bottlenecks in the production facility, though more work was required to fix the issues. Only once the constraints were identified and systems were implemented to control the bottlenecks, Alex and his team found that they needed to continuously check the system to prevent new bottlenecks from occurring or going unnoticed. The Goal provided real-life concepts that can be applied to many personal and…

  • Essay On Foster School

    everyone down two points. Likewise, if the course naturally ends in an average of 3.0, the professor would shift everyone up several points. This method of grading is used to normalize a class’s final grades and ensure a sense of equity among differing quarters that protects against outside forces that make a course either too difficult or too easy. Many Foster classes also use the curving method to inspire competition between students that pushes them to perform better. This method is…
