...Racial Tensions An unpleasant mark on the world’s history is racial tension. Although racial tension is a problem now, it has repeated itself throughout the years. Throughout time, these tensions are seen in segregation and ideas of racial superiority. These beliefs have been passed down and taught through generations in order to keep races separate. Racial hoaxes, when one race blames another race for a crime because they have issues with that particular culture, and other racial issues have been written about, made into movies, such as To Kill a Mockingbird, Lynchings in Duluth and Prom Night in Mississippi and perpetuated by those who are scared. Racial tension is as prevalent in today’s society as it was one hundred years ago, which perpetuates...

...Fences explores how racial tensions in society had an effect on an average African family in Pittsburgh. Troys’ past failure in his baseball career becomes the foundation behind his perception that his race was the reason for his failure. Due to this event he takes it out mostly on his son, Cory, cutting his hopes and dreams down primarily because he feels that his son will receive the same fate he did when he was his age. Fences also has a symbolic meaning behind it that can be linked to the two primary characters, Troy and Rose. Rose believes her family is slowly breaking apart so she feels if Troy and Cory work on building the fence then it will mend their relationship enough to hold on to. In scene II it opens with Rose singing, “Jesus, be a fence all around me every day” (Wilson 1117) which symbolizes that she her fence is made for protection. Her fence is made to keep her family safe and near her. Bono makes a comment to Troy when he questions why Rose would want a fence anyways and he basically tells Troy that, “some people build fences to keep people out…and other people build fences to keep people in (Wilson 1141).” Troy and Cory didn’t understand at first because they were too busy defying one another. All Rose did was love them and wanted the best for Cory and for Troy to drop his...

...Australians in the 70’s. Throughout the book two teenagers of opposite race become close friends and both realise the amount of racial tension in there town. After a mishap in the town Gary’s life changes and his view on life impacts how others around Gary feel about him. Gary’s sense of the racial tension in the town is clearly evident throughout the novel and it develops over the course of the book. This is made conspicuous when Gary hears Big Mac’s racist joke in the pub, saying, “And they all laughed…but I didn’t. I don’t know why, I’d laughed at the joke before. I’d even told the joke before. But tonight it didn’t seem so funny any more”. This vocal point shows how Gary is starting to become aware of the racism in his town and that his attitude towards such racism is changing. throughout the novel as he is witness to and experiences unfair and unjust actions within the narrative. Another example of racial injustice in the town is when Dumby Red is overlooked for the ‘best on ground’ award at the Grand Final presentations. Gary’s reaction is disbelief, saying, “At first I thought they’d made a mistake, or...

...LINEA DEL TIEMPO DE LOS CIENTIFICOS DE LA ELECTRICIDAD Tales de mileto Fue un filosofo griego, fundador de la escuela jónica, considerado como uno de los siete sabios de Grecia. Desde el punto de vista de la electricidad, fue el primero en descubrir que si se frota un trozo de ámbar, este atrae objetos más livianos, y aunque no llego a definir que era debido a la distribución de cargas, si creía que la electricidad residía en el objeto frotado. De aquí se ha derivado el término electricidad, proveniente de la palabra elektron, que en griego significa ámbar, y que la empezó a emplear hacia el año 1600 d. C., el físico y médico ingles Willian Gilbert, cuando encontró esta propiedad en otros muchos cuerpos. Willian Gilbert (1544-1603) se le atribuye realmente el descubrimiento de la electricidad, en un primer estudio científico sobre los fenómenos eléctricos que realizo hacia el año 1600, donde además y por primera vez aplico el término eléctrico a la fuerza que ejercen algunas substancias al ser frotadas. Este científico verifico que muchas substancias se comportaban como el ámbar al ser frotadas, atrayendo objetos livianos, mientras que otras no ejercían atracción alguna, aplicando el término eléctrica a la fuerza que ejercían estas substancias una vez frotadas. Clasificó dichas substancias: llamando a las primeras cuerpos eléctricos y a las segundas aneléctricos Fue el primero en realizar experimentos de electrostática y magnetismo, y quizás su aportación más importante...

...Purdue Extension CFS-704-2-W Consumer and Family Sciences Department of Consumer Sciences and Retailing When Your Income Drops: Fact Sheet 2 Control Stress You are experiencing tremendous changes in your life if you have lost your job, Adapted by Barbara R. Rowe and Denise Schroeder, Family Resource Management, Purdue University experienced a particularly bad year in your farm or business operation, or have gone through a divorce, a separation, or the death of a spouse. While such events differ in many respects, they may also have some important effects in common. First, crises like these are very stressful in their own right – they force us, against our wishes, to make rapid changes in our lives. Second, however irrationally, they can diminish our self-esteem. Finally, these personal crises often lead to a drop in income and security, and this introduces a host of secondary problems. Because of all these changes and the stress that can result, it is important to understand some causes, effects, and ways of handling stress to cope with difficult times. Severe and prolonged stress of the type associated with events causing loss of income can have a serious effect on a person’s physical and mental health. Stress-related exhaustion is believed to play a significant role in heart attacks, high blood pressure, cancer, and some kinds of arthritis, migraine headaches, peptic ulcers, asthma, allergies, and kidney and thyroid disease. Stress alone probably does not cause these disorders;...

Estos motores provienen de los motores polifásicos de inducción. Suponiendo que un motor de inducción comercial de jaula de ardilla se haga arrancar con el voltaje nominal de las terminales de línea de su estator desarrollará un par de arranque que hará que aumente la velocidad. Al aumentar la velocidad a partir del reposo (100% de deslizamiento) disminuye su deslizamiento y su par disminuye hasta que se desarrolla un par máximo. Esto hace que la velocidad aumente todavía más, reduciéndose en forma simultánea el deslizamiento y el par que desarrolla el motor de inducción. Los pares desarrollados al arranque y al valor de desplazamiento que produce el par máximo, en ambos exceden el par de la carga, por lo tanto la velocidad del motor aumentará hasta que el valor de desplazamiento sea tan pequeño que el par que se desarrolla se...

Dos o más transformadores se pueden conectar en distintas formas con distintos requerimientos. Cada conexión se encuentra normalizada en grupos de conexión, cada grupo contiene un índice de conexión que es multiplicado a 30° y da resultado al desfase que existen entre las tensiones del secundario respecto al primario de cada transformador. Cuando las conexiones entre devanados son distintas, varía la relación entre las tensiones en condiciones de vacío en los terminales. Para relacionar las tensiones primarias con las secundarias es necesario indicar los desfases relativos entre ellas, ya sea en el lado de baja y alta tensión. La selección de la combinación de cada tipo de conexión dependerá siempre de lo que imponga la operación y las consideraciones...

...Análisis de la influencia de electrodos verticales en una malla de puesta a tierra. Eduardo Andrés Ospina Serrano, Julián Andrés Ríos Casas, Semaria Ruiz Álvarez. Departamento de energía eléctrica y automática Facultad de Minas Universidad Nacional de Colombia – Sede Medellín Medellín Colombia eaospinas@unal.edu.co jariosca@unal.edu.co seruizal@unal.edu.co Abstract—A mesh is a very common grounding system, capable of evacuating high level currents due to faults or static discharges. Despite the symmetry of the arrangement, the current distribution along the ground is not regular and a great part of the current is evacuated by the electrodes in the periphery of the mesh. A way to make these irregularities more uniform is to place vertical electrodes along the mesh, besides this has the plus of decreasing the grounding resistance, thus, analysis of mesh with and without vertical electrodes is posed here in order to identify the behavior of the mesh in matter of grounding resistance, step and touch voltages, then manipulate the principal variables of analysis to the end of improving the performance of the mesh and establish it as a design criteria. Index Terms—Grounding system, grounding resistance, step voltage, touch voltage, vertical electrodes. proteger tanto personas como equipos evacuando corrientes provenientes de fallas y cargas estáticas entre otros. Dichos sistemas de puesta a tierra son de gran variedad y su diseño implica complejos análisis que en la mayoría de...

...Thomas “Stonewall” Jackson is greatly known for being a confederate general in the American Civil War. He supported the confederacy(slave holding states) and owned slaves during his time as a soldier. He was such a significant figure in history that he even had statues put up to honor him and his work. But with recent racial tensions (Charlottesville and BLK) Stonewall’s statues are no longer being praised. In an editorial by Warren and William Christian the great-great-grandsons of Stonewall Jackson, argue that failing to remove Jackson’s statue will just worsen racial tensions. They achieve this by summarizing and using exemplification. The authors use specific examples of how the confederate monuments are giving white supremacists a basis...

...OBJECTIVES The objectives of this experiment are as follow: • To study the rate of evaporation of water, acetone and diethyl ether. • To determine the intermolecular forces of the liquids. INTRODUCTION Evaporation is the process whereby atoms or molecules in a liquid state gain sufficient energy to enter the gaseous state. The thermal motion of a molecule must be sufficient to overcome the surface tension of the liquid in order for it to evaporate, that is, its kinetic energy must exceed the work function of cohesion at the surface. Evaporation therefore proceeds more quickly at higher temperature and in liquids with lower surface tension. Since only a small proportion of the molecules are located near the surface and are moving in the proper direction to escape at any given instant, the rate of evaporation is limited. Also, as the faster-moving molecules escape, the remaining molecules have lower average kinetic energy, and the temperature of the liquid thus decreases. In this project, we will focus on the rate of evaporation of water, acetone and diethyl ether. We can determine the major factor that cause the difference of the rate of evaporation between them. Most liquids are made up of molecules, and the levels of mutual attraction among different molecules help explain why some liquids evaporate faster than others. Intermolecular attractions that exist between the molecule of the water, acetone and diethyl ether affect...

Petit Institute for Bioengineering and Bioscience, Georgia Institute of Technology, Atlanta, GA, USA St. Joseph’s Translational Research Institute, Atlanta, GA, USA 3 University of Texas Health Science Center at San Antonio, San Antonio, TX, USA 2 ABSTRACT The surface properties of materials contribute to host cellular response and play a significant role in determining the overall success or failure of an implanted biomaterial. Rough titanium (Ti) surface microtopography and high surface free energy have been shown to enhance osteoblast maturation in vitro and increase bone formation in vivo. Whereas the surface properties of Ti are known to affect osteoblast response, host bone quality also plays a significant role in determining successful osseointegration. One factor affecting host bone quality is patient age. We examined both in vitro and in vivo whether response to Ti surface features was affected by animal age. Calvarial osteoblasts isolated from 1-, 3-, and 11-month-old rats all displayed a reduction in cell number and increases in alkaline phosphatase–specific activity and osteocalcin in response to increasing Ti surface microtopography...
