Aeroponics is the process of growing plants in air or mist environment without the use of soil. Not to be confused with hydroponics or peeponics, aeroponics is the process of spraying or fogging the roots of the plants with a nutrient solution. The plants are usually housed in troughs, tubes or foam, with the leafy part of the plants separate from the roots. Moreover, the roots are usually fully exposed and constantly sprayed with micro bursts of atomized water. Why aeroponics are used? Since plants have access to oxygen 24/7 they generally will experience faster growth than conventional means Water and nutrient used efficiently Less need for nutrients and water than traditional hydroponics systems no need to worry about weeding takes up very little space Can be made as a DIY project It uses considerably less energy and water than traditional agriculture. systems can be built as a DIY project Disadvantages of aeroponics you will need to provide nutrients as with hydroponics requires electricity for small pumps and timers as with hydroponics, you will need some form of competency to run system can be an expensive system to buy In the beginning you need to monitor the water Root crops and trees are much more difficult to grow Final words on aeroponics Aeroponics has been tested to grow cleaner, more consistent herbs like burdock at the University of Arizona’s College of Agricultural and Life Sciences.

U.S. Declaration of Independence in Spanish

U.S. Declaration of Independence in Spanish The following is a Spanish translation of the U.S. Declaration of Independence; it is believed to be in the public domain. Links are provided for the Spanish student to review some of the words and grammatical concepts used in this document. Comparisons can also be made with the original text of the Declaration. Cuando en el curso de los acontecimientos humanos se hace necesario para un pueblo disolver los và ­nculos polà ­ticos que lo han ligado a otro y tomar entre las naciones de la tierra el puesto separado e igual a que las leyes de la naturaleza y el Dios de esa naturaleza le dan derecho, un justo respeto al juicio de la humanidad exige que declare las causas que lo impulsan a la separacià ³n. Sostenemos que estas verdades son evidentes en sà ­ mismas: que todos los hombres son creados iguales; que son dotados por su Creador de ciertos derechos inalienables; que entre à ©stos estn la vida, la libertad y la bà ºsqueda de la felicidad; que para garantizar estos derechos se instituyen entre los hombres los gobiernos, que derivan sus poderes legà ­timos del consentimiento de los gobernados; que cuando quiera que una forma de gobierno se haga destructora de estos principios, el pueblo tiene el derecho a reformarla o abolirla e instituir un nuevo gobierno que se funde en dichos principios, y a organizar sus poderes en la forma que a su juicio ofrecer las mayores probabilidades de alcanzar su seguridad y felicidad. La prudencia, claro est, aconsejar que no se cambie por motivos leves y transitorios gobiernos de antiguo establecidos; y, en efecto, toda la experiencia ha demostrado que la humanidad est ms dispuesta a padecer, mientras los males sean tolerables, que a hacerse ju sticia aboliendo las formas a que est acostumbrada. Pero cuando una larga serie de abusos y usurpaciones, dirigida invariablemente al mismo objetivo, demuestra el designio de someter al pueblo a un despotismo absoluto, es su derecho, es su deber, derrocar ese gobierno y establecer nuevos resguardos para su futura seguridad. Tal ha sido el paciente sufrimiento de estas colonias; tal es ahora la necesidad que las obliga a reformar su anterior sistema de gobierno La historia del actual Rey de la Gran Bretaà ±a es una historia de repetidos agravios y usurpaciones, encaminados todos directamente hacia el establecimiento de una tiranà ­a absoluta sobre estos estados. Para probar esto, sometemos los hechos al juicio de un mundo imparcial. El Rey se ha negado a aprobar las leyes ms favorables y necesarias para el bienestar pà ºblico. Ha prohibido a sus gobernadores sancionar leyes de importancia inmediata y apremiante, a menos que su ejecucià ³n se suspenda hasta obtener su asentimiento; y una vez suspendidas se ha negado por completo a prestarles atencià ³n. Se ha rehusado a aprobar otras leyes convenientes a grandes comarcas pobladas, a menos que esos pueblos renuncien al derecho de ser representados en la Legislatura; derecho que es inestimable para el pueblo y terrible sà ­, para los tiranos. Ha convocado a los cuerpos legislativos en sitios desusados, incà ³modos y distantes del asiento de sus documentos pà ºblicos, con la sola idea de fatigarlos para cumplir con sus medidas. En repetidas ocasiones ha disuelto las Cmaras de Representantes, por oponerse con firmeza viril a sus intromisiones en los derechos del pueblo. Durante mucho tiempo, y despuà ©s de esas disoluciones, se ha negado a permitir la eleccià ³n de otras Cmaras; por lo cual, los poderes legislativos, cuyo aniquilamiento es imposible, han retornado al pueblo, sin limitacià ³n para su ejercicio; permaneciendo el Estado, mientras tanto, expuesto a todos los peligros de una invasià ³n exterior y a convulsiones internas. Ha tratado de impedir que se pueblen estos Estados, dificultando, con ese propà ³sito, las Leyes de Naturalizacià ³n de Extranjeros; rehusando aprobar otras para fomentar su inmigracià ³n y elevando las condiciones para las Nuevas Adquisiciones de Tierras. Ha entorpecido la administracià ³n de justicia al no aprobar las leyes que establecen los poderes judiciales. Ha hecho que los jueces dependan solamente de su voluntad, para poder desempeà ±ar sus cargos y en cuanto a la cantidad y pago de sus emolumentos. Ha fundado una gran diversidad de oficinas nuevas, enviando a un enjambre de funcionarios que acosan a nuestro pueblo y menguan su sustento. En tiempos de paz, ha mantenido entre nosotros ejà ©rcitos permanentes, sin el consentimiento de nuestras legislaturas. Ha influido para que la autoridad militar sea independiente de la civil y superior a ella. Se ha asociado con otros para someternos a una jurisdiccià ³n extraà ±a a nuestra constitucià ³n y no reconocida por nuestras leyes; aprobando sus actos de pretendida legislacià ³n: Para acuartelar, entre nosotros, grandes cuerpos de tropas armadas. Para protegerlos, por medio de un juicio ficticio, del castigo por los asesinatos que pudiesen cometer entre los habitantes de estos Estados. Para suspender nuestro comercio con todas las partes del mundo. Para imponernos impuestos sin nuestro consentimiento. Para privarnos, en muchos casos, de los beneficios de un juicio por jurado. Para transportarnos ms all de los mares, con el fin de ser juzgados por supuestos agravios. Para abolir en una provincia vecina el libre sistema de las leyes inglesas, estableciendo en ella un gobierno arbitrario y extendiendo sus là ­mites, con el objeto de dar un ejemplo y disponer de un instrumento adecuado para introducir el mismo gobierno absoluto en estas Colonias. Para suprimir nuestras Cartas Constitutivas, abolir nuestras leyes ms valiosas y alterar en su esencia las formas de nuestros gobiernos. Para suspender nuestras propias legislaturas y declararse investido con facultades para legislarnos en todos los casos, cualesquiera que à ©stos sean. Ha abdicado de su gobierno en estos territorios al declarar que estamos fuera de su proteccià ³n y al emprender una guerra contra nosotros. Ha saqueado nuestros mares, asolado nuestras costas, incendiado nuestras ciudades y destruido la vida de nuestro pueblo. Al presente, est transportando grandes ejà ©rcitos de extranjeros mercenarios para completar la obra de muerte, desolacià ³n y tiranà ­a, ya iniciada en circunstancias de crueldad y perfidia que apenas si encuentran paralelo en las à ©pocas ms brbaras, y por completo indignas del Jefe de una Nacià ³n civilizada. Ha obligado a nuestros conciudadanos, aprehendidos en alta mar, a que tomen armas contra su paà ­s, convirtià ©ndolos asà ­ en los verdugos de sus amigos y hermanos, o a morir bajo sus manos. Ha provocado insurrecciones intestinas entre nosotros y se ha esforzado por lanzar sobre los habitantes de nuestras fronteras a los inmisericordes indios salvajes, cuya conocida disposicià ³n para la guerra se distingue por la destruccià ³n de vidas, sin considerar edades, sexos ni condiciones. En cada etapa de estas opresiones, hemos pedido justicia en los tà ©rminos ms humildes: a nuestras repetidas peticiones se ha contestado solamente con repetidos agravios. Un Prà ­ncipe, cuyo caracter est asà ­ seà ±alado con cada uno de los actos que pueden definir a un tirano, no es digno de ser el gobernante de un pueblo libre. Tampoco hemos dejado de dirigirnos a nuestros hermanos britnicos. Los hemos prevenido de tiempo en tiempo de las tentativas de su poder legislativo para englobarnos en una jurisdiccià ³n injustificable. Les hemos recordado las circunstancias de nuestra emigracià ³n y radicacià ³n aquà ­. Hemos apelado a su innato sentido de justicia y magnanimidad, y los hemos conjurado, por los và ­nculos de nuestro parentesco, a repudiar esas usurpaciones, las cuales interrumpirà ­an inevitablemente nuestras relaciones y correspondencia. Tambià ©n ellos han sido sordos a la voz de la justicia y de la consanguinidad. Debemos, pues, convenir en la necesidad, que establece nuestra separacià ³n y considerarlos, como consideramos a las dems colectividades humanas: enemigos en la guerra, en la paz, amigos. Por lo tanto, los Representantes de los Estados Unidos de Amà ©rica, convocados en Congreso General, apelando al Juez Supremo del mundo por la rectitud de nuestras intenciones, en nombre y por la autoridad del buen pueblo de estas Colonias, solemnemente hacemos pà ºblico y declaramos: Que estas Colonias Unidas son, y deben serlo por derecho, Estados Libres e Independientes; que quedan libres de toda lealtad a la Corona Britnica, y que toda vinculacià ³n polà ­tica entre ellas y el Estado de la Gran Bretaà ±a queda y debe quedar totalmente disuelta; y que, como Estados Libres o Independientes, tienen pleno poder para hacer la guerra, concertar la paz, concertar alianzas, establecer el comercio y efectuar los actos y providencias a que tienen derecho los Estados independientes. Y en apoyo de esta Declaracià ³n, con absoluta confianza en la proteccià ³n de la Divina Providencia, empeà ±amos nuestra vida, nuestra hacienda y nuestro sagrado honor.

Equity theory 2 videos - Assignment Example Adams theory acknowledges that variable factors affect employees’ assessment and perception of their relationship with their employer and their work. Employees may be demotivated with their employer or job if they feel that their inputs are greater than the output. Therefore, the resultant effects of this will be reduced efforts, disgruntled and disruptive. In the application of this theory in a work place, it is important to consider the imbalance and the balance that exist between employees input and output in order to have satisfaction in a work place. This theory believes that a good leader will recognize the needs and well-being of the team members in order to build a highly and successful teams (Maslow, 2012, 00:03:44).

The growth of Internet betting and gambling sites and the credit card Essay

The growth of Internet betting and gambling sites and the credit card companies response - Essay Example Further, law enforcement agencies state that Internet gambling is sometimes used for money laundering (Hugel & Kelly 2002: 57). However, others consider this risk as trivial concern. The jurisdictional and anonymity concerns characteristic of Internet gambling make online gambling a potentially strong means for money launderers. The small number of prosecuted instances of money laundering linked to Internet gambling is credited to oversight and a lack of solid parameters (Hugel & Kelly 2002: 58). Still, officials form the gaming and credit card industries and regulatory agencies do not consider that Internet gambling was any more vulnerable to money laundering than other forms of electronic trade (Hugel & Kelly 2002: 58). The main objective of this review is to acquire a better understanding on the different policies and procedures of the credit card industry on Internet gambling. The review is also aimed at obtaining a broader knowledge on the strengths and weaknesses of these policies, and perhaps to formulate any potential recommendations that are possible under the Constitution. To achieve this, a review on use of the U.S. payments method --- particularly credit cards, and on the ongoing debate on Internet gambling should be made. The key points are: 1) to study the legal structure for Internet gambling activities, mainly in the U.S., but also in other countries; 2) to explain the range and characteristic of the regulations and measures the credit card industry has put into practice to prohibit the use of credit cards as a mode of payment for Internet gambling; and 3) to acquire opinions on Internet gambling’s susceptibility to money laundering. Documentation on Internet gambling policies and procedures may be requested from industry representatives; however, some might be disinclined to supply written documentation due to concerns about the confidentiality of propriety regulations. This is why conducting interviews is

The computer games are as much a part of childhood as skipping ropes and teddy bears. Nowadays children spent too much time on computer games or in consoles and it can be bad for child development. This is a habit to complaint from modern lifestyles for a lot and including limited common skills. In the modern generation when a child plays computer games it is really bad for them. Children spend many hours in front on the monitor and not going out enough could also matter general problems and they become shy person. The children become distract from more important thing like social activities and homework. The game develop nowadays become a more mad to the games and also have a weakness to lose control and become more crazy. There many complaints were found among children playing in computer for long time and they doesnt go to sleep and play till night and also doesnt eat properly for example, children play shooting, fighting and racing which can effect on body for example, they can have eyes injury, wrist, neck and back pains, headache and nerve and muscle damages.

If you want your child grow up with a healthy body, they stop playing shooting and fighting games in computer for not more than one hour. They should go out and they play outdoor games, help your mom to clean house and go with her shopping to carry some heavy bags. Describe different types of computer game There are many different types of computer games for example, action, adventure, shooting, puzzle, educational, sports, racing, simulations, combat, role- playing and strategy games. I am going to describe about 10 different types of games. Strategy games- Strategy game is about the war games and you can play in different ways. Role- playing games- A  role-playing game  (RPG) is a broad family of  games  in which players think the roles of  characters  in a made up  setting. Even you can play one player or two player games. Combat games Combat games is about battle and tank game. Simulations games- Simulation games is about to make something.

The types of puzzles to be solved can test many problem solving skills including logic and words. What is the psychological effect of games on individuals? We have all played computer games, but most of them sit in the computer for long time and they never moved for longer hour. The maker of impact games is having effects on our society. Most of the people are quite unfair on computer games effect by choosing one of the them can be also positive and negative. Computer games can also have large limits of effect in our society. Most of the games effects can be treated as good and bad. Violence is one of the main effects of games in society. Nowadays the teenagers have started to put the game violence in real life. The games have affected gamers so badly that now they are unaware of their surroundings and have effects their physical state. Games have impacted gamers mentally and physically in a negative way, as they play games they get obsessed with them, which makes them lazy as they hardly move. The main effect is when gamers keep looking at the screen their eye sight becomes weaker. The gamers are so into the games that when they go out, they try things in real which they did in game. The growing improvement in skill sound and graphics, gaming has become far more lifelike in bringing  together to what it used to be. When graphics were poor, violence such as shooting, kicking, punching did not seem intelligent and therefore it was harder to relate to what was happening on screen. Nowadays more games look and sound more lifelike, and address useful themes such as drug dealing, gangsters, wars becomes easier for more individuals to relate to these games. This practical issue can likely lead to an increase in violent thought and maybe even violent behaviour, as negative behaviour becomes more expected and accepted. Children who played a violent video game displayed a higher level of anger than children who played a nonviolent game. If a violent game is played by an individual for too long, they may become sensitive to the violence they are faced with, and this may direct to them believing that violence. The gaming can also have positive psychological effects on the gamer. It is often argued that gaming is better than watching television, as there is more communication with gaming. This communication may promote things like problem solving, planning, testing and opinion when playing the game. These factors could increase positive behaviour, such as problem solving and reasonable skills. The one simple psychological effect that gaming has on the individual that plays it. The background and the context of every gamer will mean that everyone is achieve differently. A connection between violent games and violent behaviour is quite visible. The psychological effects show that gaming has entirely personal to the individual question, and it is difficult to decide right that what affects and individual psychology. Since game alone is not to be responsible for factors such as violence or logical success. It is an improvement, one-sided to every individual.
