...clauses at the beginning tend to slow the pace of a piece. Often they are connected to a contemplative section, a heavy or serious subject and the writer wants to emphasize it. Sometimes, however, they are placed in a piece for the purpose of demonstrating the ramblings of a character, the ludicrousness of an idea, or the ridiculousness of a situation. Watch for occasional satire or irony in these long sentences. Key Questions: • How does syntax contribute to and enhance the meaning and effect of language? • How does syntax contribute to tone? 1. “Syntax” refers to the ways words and phrases are arranged to form sentences. The reader must identify an author’s syntax and discuss the relationship it has to the content of the passage. Authors may use: a. specific patterns of phrases and sentences b. divisions within a piece with different syntax for each c. parallel structure d. different sentence types e. specific kinds of punctuation f. other syntax techniques...

...A k-ω Turbulence Model for Quasi-Three-Dimensional Turbomachinery Flows Rodrick V. Chima* NASA Lewis Research Center Cleveland, Ohio 44135 Abstract A two-equation k-ω turbulence model has been developed and applied to a quasi-three-dimensional viscous analysis code for blade-to-blade flows in turbomachinery. The code includes the effects of rotation, radius change, and variable stream sheet thickness. The flow equations are given and the explicit Runge-Kutta solution scheme is described. The k-ω model equations are also given and the upwind implicit approximate-factorization solution scheme is described. Three cases were calculated: transitional flow over a flat plate, a transonic compressor rotor, and a transonic turbine vane with heat transfer. Results were compared to theory, experimental data, and to results using the Baldwin-Lomax turbulence model. The two models compared reasonably well with the data and surprisingly well with each other. Although the k-ω model behaves well numerically and simulates effects of transition, freestream turbulence, and wall roughness, it was not decisively better than the Baldwin-Lomax model for the cases considered here. The Baldwin-Lomax model is popular because it is easy to implement (at least in 2-D) and works fairly well for predicting overall turbomachinery performance. However, the model has both numerical and physical problems. Numerical problems include awkward implementation in 3-D, difficulty in finding the length scale [2]...

...becomes supersonic, shock waves form, caused either by a change in the slope of a surface, a downstream obstacle or a back pressure constraining the flow to become subsonic. In modern aerodynamics, one can cite a large number of circumstances where shock waves are present. The encounter of a shock wave with a boundary layer results in complex phenomena because of the rapid retardation of the boundary layer flow and the propagation of the shock in a multilayered structure. The consequence of shock wave/ boundary layer interaction (SWBLI) are multiple and often critical for the vehicle or machine performance. The shock submits the boundary layer to an adverse pressure gradient which may strongly distort its velocity profile. At the same time, in turbulent flows, turbulence production is enhanced which amplifies the viscous dissipation leading to aggravated performance losses. In addition, shock-induced separation most often results in large unsteadiness which can damage the vehicle structure or, at least, severely limit its performance. The article first presents basic and well-established results on the physics of SWBLI corresponding to a description in terms of an average two-dimensional steady flow. Such a description allows apprehending the essential properties of SWBLIs and drawing the main features of the overall flow structure associated with SWBLI. Then, some emphasis is placed on unsteadiness in SWBLI which constitutes a salient feature of Communicated by A. Hadjadj. J. Délery ONERA/DAFE...

...Michael Poteet Poteet 1 Professor Lesser English 116 December 8, 2011 Comparisons and Dissimilarity of Love Octavio Paz, Franz Kafka, and Anton Chekhov, despite living in different eras and locations had similar sentience while going through many different experiences in life. This fact demonstrates the value of comparison but also the ability to contrast to understand life. Through “The Lady With the Dog”, “The Hunger Artist”, and “My Life With the Wave”, the reader is able to conclude: The stories while being decidedly different in diegesis’s also contain similarities in the symbolic contrivances used throughout all three stories Upon reading “The Lady with the Dog” by Chekhov the reader cannot help but sympathize with Anna and Dmitri. Sadly the timing of the relationship is unfortunate. The characters ultimately act in ignorance, because they do not find satisfaction in the relationships with their spouses so they choose to find it somewhere else. This is where are the pain the characters are feeling is coming from. Because sexual intimacy is so powerful and brings couples together into one “person” it causes so much pain for the couple because they have felt that feeling and cannot have it. They both meet their fate in love by finding their true match in one another, but very rarely do fate and timing coincide with one another, so they are forced to continually meet in secrecy through out the story.

All in all the situation is a little bit strange and not at all profitable for the Dominican Republic as long as the country does not take any benefit from the tourism in spite of the fact that these foreigners make use of the land, beach, resources and manpower for free. 3.1 General Aspects 3.1.1. Location The Dominican Republic is a small country in the world however it has a dominant place in the Caribbean area as being ranked the second on top of the largest countries in the Caribbean archipelago. With a population of 8 million and a half, the Dominican Republic has a total area of 49, 390 square kilometers. The neighbors are as it follows: ( CIA Wordl Factbook 2000) - in the west- Cuba - in the east – Mona Passage that separates two islands, Hispaniola and Puerto Rico - in the north – - in the south – The Caribbean Sea - in the north –The Atlantic Ocean 3.1.2 Natural Resources and the Environment The beauty of the country is rendered by the mix-up of the high and lowland areas, rivers and lakes, including offshore islands. The Dominican Republic displays beautiful mountain ranges covered with forests, Pico Duarte being the highest mountain in the Caribbean and plains such as the Coastal Plain of Santo Domingo. Despite not having been blessed with natural lakes, The Yaque del Norte represents the longest river in here, crossing the most fertile area, The Cibao Valley.

...Integrative Paper Kotter and Cohen’s The Heart of Change Ivancevich, Konopaske and Matteson’s Organizational Behavior and Management Introduction Kotter and Cohen’s The Heart of Change is written with the premise that “people change what they do less because they are given analysis that shifts their thinking than because they are shown a truth that influences their feelings” (Kotter and Cohen, p. 1). This is an extremely powerful message and important for organizations to understand if they are going to be successful at implementing a large-scale organizational change. The Heart of Change describes how companies can effectively transform their organization to better succeed in the constantly changing, turbulent society we live in today. Kotter and Cohen’s strategy for successful reorganization is described in an eight-step process. Ivancevich, Konopaske and Matteson’s Organizational Behavior and Management, builds on the ideas presented in The Heart of Change by giving a more in-depth explanation of organizational behaviors, processes and changes. Both of these readings offer a better understanding of how shifting the behaviors and emotions of an organization’s employees is essential in succeeding at organizational change. Discussion Step one of Kotter and Cohen’s The Heart of Change is the most significant of all eight steps. Step one involves the need to create a sense of urgency throughout the workforce to begin the process of organizational change...

...Technology Abstract: The relationship between capital structure and return on equity is examined. It is shown that for banks in the U.S., for the relatively less regulated 1983 to 1989 period as well as the more highly regulated 1996 to 2002 period, there is a positive relationship between financial leverage and the return on equity. The analysis is extended to determine the relationship between return on assets and equity capital. The evidence supports the hypothesis that there is a positive relationship between equity capital and return on assets. Relevance to Practice: Previous empirical evidence for U.S. banks had indicated a perverse negative relationship between financial leverage and the return on equity for the 1983 to 1989 period. The cause of such an association was attributed to a reputation effect for large banks who adopted an aggressive capital structure. These contrary findings coupled with regulations on improving equity capital adequacy from the Basel II accord supported the efforts to promote a reduced capital structure risk posture by banks. However, these opposite results conflicted with traditional thought from the DuPont analysis wherein, when operating profitability is positive, increased financial leverage augments the return on equity. Thus, banks continue to have an incentive to ratchet up their financial leverage so as to increase the returns to stockholders albeit with increased financial risk.

RATIONALE OF THE PROPOSED INVESTIGATION For developing countries, special economic zones (SEZs) traditionally have had both a policy and an infrastructure rationale. In terms of policy, the SEZ can be a useful tool as part of an overall economic growth strategy to enhance industry competitiveness and attract foreign direct investment (FDI). Through SEZs, governments aim to develop and diversify exports while maintaining protective barriers, to create jobs, and to pilot new policies and approaches (for example, in customs, legal, labor, and public private partnership aspects). SEZs also allow for more efficient government supervision of enterprises, provision of off-site infrastructure, and environmental controls. The category SEZ includes free trade zones (FTZ), export processing Zones (EPZ), free Zones (FZ), industrial parks or industrial estates (IE), free ports, free economic zones, and urban enterprise zones. LITERATURE REVIEW 1) Introduction In this research paper sector specific studies are conducted that analyze efficiency and its variations over the years and studies attempting to shed light on variations in terms of efficiency...

...Chapter 1 INTRODUCTION The project ‘Heat Transfer Studies on a 7.5 Watt LED Lighting Load using Finite Element Analysis’ is mainly concerned with the heat generated by an LED lighting load and its dissipation to the surrounding such that the LED junction temperature is maintained low. The LED chosen for this project is 7.5 Watt, which has a maximum operating temperature of around 80°C, exceeding which the LED will fail. The LED is best operated at room temperature conditions and may be just above. The project implements a specific method of cooling or rather maintaining the LED junction temperature as low as possible by using a Thermo Electric Cooling device, more specifically known as the Peltier device. The project looks into the various methods by which a Peltier cooler can be implemented such as, with or without a fan or simply a fan would provide sufficient cooling for the LED module. A Heat sink is a necessary component which is always associated with cooling electronic components. Before getting into the depth of the project detailing we will look into the basic components that have been used in the project setup which include: a. LED Module b. Peltier Cooler c. Heat Sink d. Cooling Fan 1.1 Light Emitting Diode: Light-emitting diodes (LEDs) are small but powerful devices in terms of their diverse applications.

...ENGLISH HANDBOOK -“Welcome to my evil lair…” -Mr. Braiman Brooklyn High School of the Arts www.mrbraiman.com http://handbook.mrbraiman.com “EVIL” Welcome to my evil classroom lair. In order to become full-fledged evil “minions,” you need to read this handbook carefully. It explains everything you need to know. “English,” as you may know, is shorthand for “English Language Arts.” Being that we are in an Arts school, but one where academics must and always do come first, it is important that we approach the subject as what it is: an art form. How does one study the arts? What exactly do we do when we study drawing, sculpture, music, or dance? Well, anyone who has studied the arts will tell you that studying the arts essentially involves two things: • Learning about, and developing an awareness of and appreciation for, existing works of art in that particular form; • Developing the skills and techniques associated with the art form, in order to create our own works. In the case of language arts, much like any other art form, we will be studying existing works of art (i.e., reading books, stories and poems), and developing the skills to produce our own (i.e., writing). That’s what English Language Arts is. We will also be preparing ourselves for New York State’s Regents Comprehensive Examination in English, which we’ll all be taking in June. This two-day, six-hour, four-part exam requires no specific knowledge or content, but it does require the skills to listen, read,...
