Arab Nationalism in the Modern Context

Arab Nationalism in the Modern Context ‘Arab Nationalism’ was an important part of anti-colonial struggle. A generation on it has little meaning today. Discuss. This essay will examine to what extent Arab nationalism as an ideology was of significance to the anti-colonial struggle and the influence of Arab nationalism in present times. A prominent question of interest in this study will be: was western domination eliminated due to the might of Arab nationalism? Certainly there has been a debate surrounding the significance of Arab nationalism today, this essay will highlight central issues surrounding the debate such as whether Arab nationalism has terminally declined or has just become a lessened force. A further question of concern will be: If Arab nationalism has gone into political remission could it be revived or gain appeal in present times? Furthermore this study will analyse when Arab nationalism was at its strongest and when the greatest expression of Arab nationalism were evident. Arab nationalism is considered to be a nationalist ideology which objective is to achieve a unified Arab nation encompassing the entire territory which is categorised as â€Å"the Arab World† from the Atlantic Ocean to the Persian Gulf (Karsh Arab nationalism and the set of beliefs surrounding the ideology were believed to have the capability to dissolve such matters in order to redeem and revert back to an indigenous culture and heritage. Most of the Arab world experienced colonial suppression and were ruled by western powers such as Britain and France. Was Arab nationalism vital in the struggle against colonialism? It is deemed that â€Å"†¦through the imperial world during the decolonizing period, protest, resistance, and independence movements were fuelled by one or another nationalism† (Said, 1993). The end of the Second World War caused vast political, social and economic transformations to the world order subsequently certain colonised nations gained their independence. In spite of this, the end of explicit or direct colonialism obviously did not equate to the termination of colonial dominance. European powers sought to retain their power across the Middle East and North Africa and colonialism still dominated large parts of the region. European imperialist presence was still evident as certain monarchies were under their rule and were still well disposed to them. For example, Egypt had been granted independence by the British in 1933 however Britain still played a direct role in Egyptian affairs and exercised a huge influence over the nation. It would be in this context that Arab nationalism would serve to provide a compelling set of beliefs and gain ground as a robust force in opposition to foreign occupation. Rafik Asha deemed that â€Å"(Arab) nationalism constitutes the vital soul-force of our people, the bloodstream of Arab life and political vitality, the spirit which guides a resurgent people towards freedom from domination, servitude and pat ronage† (Pfaff, 1970). The Arab nationalist movement was immensely advanced by Gamal Abdel Nasser whom attained power in Egypt and became the nation’s president. In 1956, Nasser nationalised the Suez Canal which had still been occupied by the British. Furthermore, he fought against British, French and Israeli hostility and attacks towards Egypt later on that year. Both these forms of action exhibited a defiant attitude towards the Western powers and inevitably forced them into submission. During this epoch, Arab nationalism gained immense support and popularity throughout the Middle East and North Africa due to Nasser’s leadership furthermore many people in other Arab nations believed that they shared a common struggle against colonial powers.

Double Feed Induction Machine (DFIM) model in d-q coordinates system Research Paper

Double Feed Induction Machine (DFIM) model in d-q coordinates system. Induction Motomr example of application in practice (variable speed drives) - Research Paper Example The stator is fed by a fixed voltage sources while the rotor is fed by a variable source. Both the stator and the rotor are connected to a three phase power frequency. Mathematically it is convenient to express the three phase voltage concept of DFIM in a dq coordinate system. A (d, q) coordinate system refers to direct and quadrature axes along which current is aligned. A good example that shows the application of an induction machine is the Growian wind turbine that has DFIM as part of its energy regulating system (Anahua et al, 8). A Growian wind turbine which was first used in Germany the year 1977 could be among the first induction models in a (d, q) coordinate system. It came about as a result of three German utilities forming the Growian Company whose function was to design and test a huge wind energy alteration system. It had a variable speed drive with a teetered rotor that had full-span pitch and variable speed force train made of power electronics. The engineers came up with a trade-off between a generator whose frequency converter is in the stator circuit and a doubly fed induction machine whose frequency converter is situated in rotor circuit (Anahua et al, 56). It is characterized by the magnitude of aspect such as amount of voltage, speed, and flux. It is based on the assumptions the stator and rotor voltage acts as the input regulators depending on the flux density distribution, as well as, the electromagnetic condition. Additionally, the rotor current and stator flux also work as the variables. The converters control the rotor voltage to acquire the desired floe of current and the reactive power. The power reaction and resistance is viable in managing the magnetic saturation a transformation is clearly indicated by a mathematical equation. Disconnecting the machine from the grid, lead to a reduction of stator current to zero. This breaks the circuit which is an indication that DFIM model

Consommation (in French) Essay Example | Topics and Well Written Essays - 750 words

Consommation (in French) - Essay Example Mais cette expà ©rience moderne est trà ¨s diffà ©rente de celle du passà ©, quand faire les achats à ©tait un processus plus long, qui demandait plus d’à ©nergie. Aujourd’hui, je suis sà »r que les produits procurà ©s dans le supermarchà © sont de bonne qualità ©, puisqu’ils sont bien rà ©glementà ©s et bien gà ©rà ©. Le stock contient une gamme varià ©e de produits, mà ªme des apparats à ©lectriques, qui sont moins cher que les autres produits dans les petits magasins. Je pense qu’il vaut mieux acheter des produits qui sont situà ©s sous le mà ªme toit ou je suis plus attentif à   ce que j’achà ¨te. Faire des courses est, donc, une expà ©rience rafraà ®chissante et facile. Mais quand j’à ©tais enfant, jhabitais dans une petite ville en Irlande dans les annà ©es quatre vingt, ou il ny avait pas de grandes chaà ®nes de supermarchà ©s. Ma famille et moi faisaient les achats le samedi matin dans un marchà © ou nous achetions nos fruits et nos là ©gumes; il prenait au moins quatre heures pour finir les courses. On trouvait du pain à   la boulangerie et de la viande à   la boucherie, ou les produits à ©taient toujours frais et personne n’à ©tait mà ©fiant de leur bonne qualità ©. En plus, ma mà ¨re parlait avec les autres clients, donc on sentait une forte sensation dappartenir à   la communautà © et les petites entreprises et commerà §ants à ©taient une partie de notre culture et notre identità ©. J’ai alors pris cette tradition avec moi et aujourd’hui, je vais aussi aux petits commerà §ants pour certains ingrà ©dients, comme pain, lait, fromage ou chocolat parce que ma famille en mange beaucoup. Maintenant, les petites entreprises ont disparu et ont à ©tà © remplacà ©es par les grandes chaà ®nes de supermarchà ©s. Toutefois, je ne suis pas triste; au contraire, jaime la convenance moderne. Je crois que les communautà ©s ont besoin dun centre commercial proche pour acheter les choses nà ©cessaires sans grand effort. Aussi, nous habitons dans une socià ©tà © multiculturelle et cest important
