...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;...

...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...

...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.

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...

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...

...relationships. Developed by communication scholars Leslie Baxter, Barbara Montgomery and their colleagues, the dialectical perspective assumes that relationships keep changing. They are not maintained, but rather sustained through changing statuses. There are three sets of tensions that are common in relationships: integration-separation; stability-change; and expression-privacy. The first dialectic identified is integration – separation, more commonly known as autonomy versus connection. This is the tension in a relationship where either partner desires to be independent but also connected. The desire for different levels of autonomy and connection can generate friction in relationships. In the initial phase of the relationship we are like actors in a play trying to please the audience. But we cannot repress who we are for too long. Eventually we have to let our true selves show. An example of this is when a couple is in the beginning stages of the relationship, they are spending all of their time together and all is going fine. As time goes along either partner wants to start doing things independently. He/she wants to hang out with friends and have “alone time”. This can create tension in the relationship because the partner might not want to be left out. It is very common for the relationship to become strained at this point. It is a contrast from spending great amounts of time together; and either partner can feel betrayed. A solution for this would be for...

...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...

...Does Soap Affect the Surface Tension of Water? Background: Surface tension refers to water's ability to "stick to itself". Surface tensioncan be measured and observed by dropping water (drop by drop) onto a penny. Thenumber of water drops that can fit on a penny will surprise you. Question: How does soap affect the water’s surface tension? Hypothesis: I think that the surface tension of soapy water will be less than that of freshwater because H 2 0 has strong polar bonds, and when water is mixed with soap the polar bonds which help to bind the water together are weakened, thus lessening the surfacetension. Materials: pipette, liquid soap, water, beakers, penny, graduated cylinder, paper towels. Procedure: 1. I received a beaker filled with tap water. 2. I took a pipette and filled it upwith water from the beaker. 3. I began to add drops of water to a penny, which was headsup, every one second from a height of ½ centimeter and counting how many drops I had put on it. 4. After I added the drop that caused the water to flow over, I recorded howmany drops stayed on the penny, and I then dried the penny with a paper towel. 5. Irepeated steps two through four, four times. 6. I took 100 ml of water and poured it into a beaker. 7. I got 3 ml of soap. 8. I added the 3 ml of soap to the beaker and stirred thesolution 40-50 times with a fresh pipette. 9. I filled the pipette with the soapy water solution and began to start adding drops of the solution to the same penny, from...

...Kevin Richards Ms.Battle English 10 (3A/B) 1/5/13 My Essay This speech speaks about racial tension, white privilege, and race inequality and how the United States is not the union we want it to be. This speech was delivered by Senator Barack Obama, a father to two daughters and a husband to a wonderful woman. Senator Barack Obama feels that the United States is not how it said it will be due to racism, unfairness to each other races and privileges white people had over races, he felt that it was unbalanced and needed to make a change right away. I think he wanted to tap in to the audience emotions, so for them, they can make a change to form a more perfect union, he also explained that with enough effort, anything can happen as he made an example towards Ashley. One of the significant phrase a, liked was when he said “I am the son of a black man from Kenya and a white woman from Kansas. I was raised with the help of a white grandfather who survived a Depression to serve in Patton’s Army during World War II and a white grandmother who worked on a bomber assembly line at Fort Leavenworth while he was overseas.” He is saying that he was raised by both African and White, so he is confused to why the United States is like this? Senator Barack Obama was arguing about racial issues that was occurring in the United States, and why is not everyone treated equality. In his speech h often switch to topic to topic, for example.

...Psychology and Health Problem Axia College/ Ps In this essay I will explain how the multi-factorial model of psychology affects a person’s psychological state and health, since they usually go hand and hand. The multi-factorial model is used by psychologists to examine how biological factors, environmental factors, sociocultural factors, personality factors, behavioral responses, and various stressors are connected to health. Biological factors include genetics, gender, age, ethnicity, medical history, and a person's family history of diseases or illnesses. Biological factors are pivotal to understanding the multi-factorial model because it aids researchers in identifying the diseases and other ailments that are a part of someone's family history. For example, if illnesses such as Alzheimer's and heart disease have been a part of an individual's family for many years that person may be predisposed to these illnesses, which increases their likelihood of getting these illnesses more than other people who do not have the family history of Alzheimer's and heart disease. Another part of the multi-factorial is environmental factors, including natural disasters, pollution, and water quality. Pollution is an environmental issue that can cause to illnesses. Carbon monoxide, a colorless, odorless gas found in cigarette smoke, auto fumes, and smog, decreases the oxygen-carrying capacity of the blood (Nevid and Rathus, 2005). Carbon monoxide affects...
