Superfund sites Essay Example for Free

Superfund sites Essay Superfund sites are defined as any land in the U. S that has been polluted by hazardous wastes and requires cleanup process as it poses as risk to human health and the environment, (Environmental Protection Agency, (EPA), 2007). One of the sites in the state of Texas (Superfund Information Systems, 2007), is the â€Å"BAILEY WASTE DISPOSAL† (EPA ID: TXD980864649). National Priorities Listing (NPL) had got the site listed on 5th October 1984. According to BAILEY WASTE DISPOSAL (ORANGE COUNTY) TEXAS(2008), the site has a population of 7,600 people which is within 3 miles. The site is a marshy area near the Neches River and the Sabine Lake, occupying 10 acres. Some of the main contaminants in the area are benzene, metals, phenols, chlorinated hydrocarbons in soil, arsenic compounds, naphthalenes and pyridines. The waste volume is about 156,000 cubic yards. The contaminated media was sediments and solid waste. If the site is not suited for human exposure then a study is undertaken to check for contamination and the posing risk to human health. Some of the risks posed by these contaminants are as follows, direct contact (causes cancer), surface contact (marsh have been effected) and ground water (contains organic compounds and metals). The remedy was put into place in June 1998 which consisted of consolidation of sediments that were affected from marsh, drains, channels and drum disposals. The next step involved stabilization of waste and construction of to cover the stabilized waste. Some of the other remedial activities undertaken were evaluation of soil and waste, relocation and consolidation of shallow wastes, clay dike construction, construction of roads, closing of piezometers wells and wastewater treatment plant constructions that includes decontamination of water active area storm waters and dewatering operations from ground water. There is also a constant monitoring of air to check if action levels are not exceeded on the site. Some of the activities that were achieved during 8th February 2006 and 1st May 2006 are excavations of affected and waste sediments which were transported or relocated to industrial landfills for disposal and solidification, verification of waste and sediments. This process also included placement of soil cover. The deletion process has been successfully done on the 15 October 2007. The non-residential land included 10 acres. The major milestones of the site are present status of the site are Final Assessment Decision was taken on the 15 October 1984. This is followed by the Final remedial action on the 16th December 1996. The human exposure control is underway presently. The contamination groundwater migration under control report says that this site is not a ground water site and finally the construction has been declared complete as of 14 September 1998. After the complete remedial process some of these sites may or may not be used for recreational purposes. These sites then come under non-residential use, residential use or land reuse. Once the complete risk analysis is done the EPA takes the action of controlling any human exposure until the cleanup process is done. At the BAILEY WASTE DISPOSAL (ORANGE COUNTY) TEXAS, site as of now has human health and environment protections and safety under control and there is no potential risk to human health or the environment.

Event Driven Programming

Event Driven Programming P1 Describe the key features of event driven programming Event handlers The GUI is formed of a great deal of built in things such as text boxes, tool icons menus etc. When the user clicks on a mouse or presses a key on the keyboard they trigger these GUI features. This sort of interaction is called events. Windows operating systems provide the event driven program with these event triggers. The code is written so that it reacts to every event that arise through user interaction. Events are the activities which are carried out by the user when the program is being used. When the user clicks on any object then the Click event is executed. If the user repositions the mouse then the mouse move event occurs. By the similar method a program can produce Key down event, Key up event, mouse double click event. The event is perceived by a form or control. Code is initiated by a program in reaction to an event. All forms and controls in VB have a set of events already in place. If one of these events takes place, VB brings up the code in the related event process. Despite the fact that predefined collection of events are detected without human intervention by objects in VBA, it still up to the programmer to decide if and how they react to a specific event. Event procedures are written for events in order to make a control respond to an event. Different objects can trigger different event processes when an event happens, although a lot of objects recognise the same event. For instance,if a user clicks a userform, the Userform_Click event process takes place; if a user clicks a command button named CommandButton1, the CommandButton1_Click event procedure is triggered. Usually there are two different types of events. There are the events which are triggered by user interaction (clicking on a mouse, pressing a key on the keyboard) and there are System initiated events which are events produced to respond to a user action (scrolling text, highlight a button). Both of these events have to be dealt with in a UI. It is also possible that a user event triggers a system initiated event. What happens in a classic event driven application is the user opens the program and triggers an event by clicking on a button or pressing a key on the keyboard or the code in the program can trigger an event for example loading a form from the Load event procedure. The event is received by the program. If there is an event procedure in place for that particular event then the task is performed. The program then waits for another event to happen.   An event handler deals with these events. All events are parts of data from the main configuration usually the GUI toolkit. Event handlers are very important elements of event driven programming. The events are generated by the structure found on understanding lower-level interactions, which could be lower-level events themselves. For instance, by moving the mouse the program takes this to be a menu selection and timers running out. The events primarily are initiated from actions on the operating system level, for example, interrupts produced by hardware devices, software interrupt instructions, or state changes in polling. In these circumstances interrupt handlers and signal handlers relate to event handlers. An event loop is where the program takes delivery of an event, deals with the event and then waits for another event and then executes a trigger function to deal with it. Trigger functions are written to correspond to the necessary actions. The algorithm which has been prog rammed has to make sure that triggers which have been made available are performed as soon as they are required which as a result presents a software concept that imitates an interrupt driven structure. The event loop normally doesnt stop until the user closes the program. When it receives the event it initiates the suitable event handler. This will ultimately be built-in to your application as a window. You can insert controls to this which might include a text box, check box command buttons etc Every event is examined by a dispatcher so that it can decide what sort of event it is, and the event is then sent by the dispatcher to the associated handler so that the particular event can be processed. The dispatcher has to deal with a flow of input events. Once an event is transmitted it has to be looped back so that it can deal with the next event, this is done via the event loop. Several programs particularly those which control hardware could be endless and consequently would have to designate a special event to end the event stream (an end of file marker or pressing the escape key). For this to happen there has to be a quit facility in the dispatcher logic, so that an event looped can be stopped when the special event is found. In some circumstances, the dispatcher could decide that there is no suitable handler for the event. When this happens, the event could be ignored or an exception could be initiated. Events that dont have handlers would be ignored by A GUI program because GUI programs are only concerned about particular types of events. For example although it might act on a mouse click it may not act on mouse movement. In the majority of other programs if an event is not recognised then it is regarded as an error which causes an exception to be initiated. There is an event queue which is used for storing events when the dispatchers or handlers cant deal with the events as quickly as they come in. The events queue is brought in to the events stream where the stream can be temporarily held. When an event comes in it is put to the back of the queue and the dispatcher deals with the events at the front of the queue as quick as possible. Most GUI programs have an event queue. It might take longer to process larger events like mouse clicks, so at the same time this event is being dealt with other events such as mouse movement might build up in the queue however as soon as the dispatcher is ready it can quickly get rid of the meaningless mouse movement events so that the event queue is cleared out quickly. P2 What is most noticeable in event driven programming is the flexibility that it provides, and the way in which it makes an effort to be as modeless as much as it can.. Graphical user interface applications are usually programmed in an event driven way. Event Driven Programming is relatively easy to do especially in Visual Basic because they have incorporated some revolutionary tools to help us along. Drag and drop design tools, property sheets, plus click and code aids helps make EDP less of a burden. Because of the flexibility offered with Event driven programming, it is an extremely popular method, especially for creating GUI programs. With Visual Basic EDP is simple because we are given various design tools to work with in order to produce user interface components (windows and dialog boxes) On top of this we are also provided with a complete suite of Windows interface components (including command buttons, text fields, list boxes, pictures, drop-down menus and file system contr ols) which can be created at the touch of a button without the need to write any code.   The forms engine for producing the interface applies technology obtained from Cooper Software.  We can then add functionality to these interface components, which react to events. By programming in EDP we are also able to adapt procedures quickly and respond to faults. Event Driven programs are used in in Automatic Teller Machines (ATM), Point of Sale (POS) systems, certain types of smart cards, Internet kiosks and handheld devices M1 Windows Operating systems are event driven programs in two ways. In one way it is similar to EDP because it uses interrupt handlers which are used as direct event handlers for hardware events, but replaces the job of the dispatcher with CPU hardware. In Windows Operating systems, data and software interrupts are transferred to user processes which usually are written as event handlers themselves, so in short the Operating system perform as dispatchers. Microsoft Windows take action when initiated by messages which are sent to the main application thread. So that the program can receive these messages the program continuously calls the GetMessage function which is found in the event loop. This means that Microsoft Windows is event based. Once a little elective processing has been carried out, the DispatchMessage() is summoned to dispatch the message to the appropriate handler which is called the WindowProc. In Microsoft Windows a message loop is created by user-interactive procedures to react to events, the message is connected to the event and is forced on the OS. The event doesnt just have to be user interaction but can also be things like network traffic, system processing and timer activity. Windows operating systems also have an event queue (or message queue as it is in Windows) which is where the messages are kept. Messages are dispatched to a particular job among a cluster of collaborative jobs. Messages are received by a window handle object via a WinProc, all of which correspond to an independent task in that system. In order for the next message to be dispatched a task has to finish its job as quickly as possible. D1 Event driven Programs are able to set off warnings, based on business policies. With the network and applications repeatedly collecting and sharing observed events, organizations get direct access to â€Å"in-context† data on the root of the problem and the consequences if it was to happen. This facilitates combined decision-making which gives an organisation the power to avoid unfavourable situations and, finally, to enhance competiveness in numerous aspects. For example, if a sensor discovers that part of the equipment in an isolated plant has broke down. This data is linked to a customer contract which has a service-level agreement with it. A warning corresponding to the equipment which has broke down and its effect on the customer contract is dispatched to the appropriate personnel throughout the business —business analysts, plant operations, and production control personnel. At the same time, a meeting can be set up with these people so that they can consider th e effect of the fault, when it will be fixed, and how business procedures should be altered so that they are better prepare if it was to happen again in the future. Events dont just have to be triggered by user interaction but can also be triggered by other applications (application events) or by system events such as alarms or warnings. Copied Modern business processes often require the blending of automation into the work environment through the invocation of behind-the-scenes functions and procedures. Behind-the-scenes tasks can include the automatic production of output such as an invoice that prints automatically when an order is processed, a Web site that is automatically updated with current data, or an automatic e-mail with fresh report output when a transaction is completed. A solution often adopted is to write the application in the style of an event driven system. That is, something happening and to which a task should respond, is modelled as an event. The event is put together by a central thread of control, with the event and thread of execution being handed over to the appropriate task. It is now the tasks job to deal with that event and subsequently return the thread of execution back to the executive or dispatcher. In an event driven system, a task, when allowed to run, must return control when it no longer requires it or when it can not precede further. That is, the task cannot perform an operation which would cause execution to block within that task. If the task was half way through an operation and was waiting on more data, it would need to remember where it was and return. When the data it was waiting on arrived it would then continue from where it had previously stopped. The thread of execution must be given back to the dispatcher in order to allow other tasks to run and deal with their own events. The tasks therefore must cooperate with each other to ensure that all are able to get through their respective jobs. At a lower level, an event driven system can also be viewed as being a form of simulation system. In simulation systems, there is a list of jobs to be performed. The central executive or dispatcher retrieves the first job from the list and executes the code associated with the job. The code must eventually return so that succeeding jobs in the list can be executed. If it was not possible to finish an operation, the code for that job would add a new job to the end of the list of jobs such that the operation could be completed at a later time. The main difference with an event driven system is that the central executive or dispatcher must be aware of a number of primary event sources. When the dispatcher goes to retrieve the next job to execute, it must also check the event sources and if an event is waiting, create a job for the delivery of the event to the appropriate task. In a simulation system, when there are no more jobs to execute the program would terminate. For an event driven system, while ever any of the primary event sources are active and tasks are interested in events from those sources, the process will continue to execute. This means that if there were no jobs to execute in the list of jobs, the process would block and wait for an event to arrive. As the process itself is blocked, those events will of necessity be the result of some stimulus from the operating system. For example, a timer or alarm expiring, a signal being directed at the process, or data being ready for the process to read. But first, what are the business opportunities enabled by EDA and where do they exist? Consider the airline industry as a good example. Airline operators monitor weather sources, customer reservations, and air traffic control in real-time to manage their daily flight schedules. Their event-driven systems provide pricing adjustments and re-scheduling based on the real-time, complex analysis of those event streams in order to maximise their profitability and operational efficiency. This is a classic EDA benefit: optimised business operations with real-time information and increased operating margins Almost every company has a daily operational aspect that can benefit from an EDA solution. A poultry processor in the midwestern United States provides an example from the manufacturing sector. This processor utilises distributed cooling equipment throughout its plant to keep the temperature below 50 degrees as per U.S. Department of Agriculture regulations. Equipment malfunctions are very costly to the business all products within the processing area must be scrapped if the temperature rises above 50 degrees. The coolant substance is also a potentially harmful chemical, thus any leaks requires a plant evacuation. For all these reasons, the cooling equipment must be closely monitored and maintained, 247. This monitoring and maintenance is typically done on a regularly scheduled basis around the clock. That requires significant resources however, so the company implemented an EDA solution that included physical sensors to capture equipment diagnostic information across the plant. The diagnostic information is now automatically captured and analysed every few minutes, making it easy to identify pieces that are potential candidates for failure. Not only can they fix the equipment before it breaks, but they have also alleviated the need for round the clock maintenance staff in favour of a more management-by-exception approach. Greater efficiency and lower costs are not the only benefits. Companies are also using EDA solutions to generate a competitive advantage in their industries by providing unique and differentiated real-time services. EDA solutions provide excellent opportunities for companies to become a leader in their industry, through better management of their daily operations and the unique services they can provide to their customers. These solutions take advantage of existing IT investments, creating more value through the analysis and processing of events that already exist within most applications and IT systems. As EDA solutions have evolved into more standards-based and open systems, the speed and cost of implementation have also greatly decreased, making now an attractive time to invest.

Poverty and Culture One of the common liberal claim is that all "the poor are just like everyone else except that they have less money." – Anonymous The Poverty Poverty is hunger, Poverty is lack of shelter, and Poverty is being sick and not being able to see a doctor. Poverty is not being able to go to school and not knowing how to read. Poverty is not having a job, is fear for the future, living one day at a time. Poverty is losing a child to illness brought about by contaminated water. Poverty is powerlessness, lack of representation and freedom. Poverty has many faces, changing from place to place and across time, and has been described in many ways. More often, poverty is a situation people want to escape. So poverty is a call to action for the poor and the wealthy alike. This is a call to change the world so that many more may have enough to eat, adequate shelter, access to education and health, protection from violence, and a voice in what happens in their communitie s. As poverty has many dimensions, it has to be looked at through a variety of indicators, levels of income and consumption, social indicators, and now increasingly indicators of vulnerability to risks and of socio/political access. Culture Culture of any land or nation can tell us about its way of living, standards, priorities, attitudes, styles, and behaviors. Culture of any society can completed in decades or even centuries, we cannot change it rapidly. We here can discuss about the Culture of Poverty, how it is cultivated, and what factors can influence to this â€Å"Poverty Culture†. Influential factors There are many factors playing a much major role in the deficiency (not able to compete) rather than we can only talk about literacy of any nation/country... ... up with this tremendous population explosion. So far, much more work has been done using consumption or income-based measures of poverty; some work also has been done on non-income dimensions of poverty, but we should have to consider all aspects of poverty and don’t need to stick over certain area.

Racism in To Kill A Mocking Bird :: essays research papers

Bullying And Discrimination Differences in the social status are observed considerably large in the society of Maycomb. Scout and Jem are two little children who are growing up, observing all the complicated incidents and trying to understand them. In the Maycomb County, incidents get more and more complicated as the dilemma of racism becomes bigger and bigger and as wise Atticus starts loosing faith in the good in people. Maycomb’s society is like a hierarchy. On the top there is Atticus Finch, he always tries to believe the good people. The ignorant farmers Cunningham’s are below the towns’ people, which are below Finches. The Ewell’s even lower on the society and the black society comes after them despite all of their honourable and respectable conditions. The place where black society stands on the social hierarchy enables Bob Ewell to cover his obscure presence by putting Tom Robinson down. Jem and Scout are growing in this society and Atticus keeps on trying to teach them to look at situations from another persons’ perspective to understand it better. This is like a moral lesson to the reader from Harper Lee. It is something that applies to everyone. The huge difference in social status is very destructive for the community and for Scout. For example, Scout doesn’t understand why Aunt Alexander doesn’t let her be friends with young Cunningham. Harp er Lee uses children’s naivety and simplicity to show the complexities of the adult world and prejudice in human interaction. Atticus grows his children to be fair and equal. He is a very wise man, who in many situations knows how to act and what to do. In a racist society like Maycomb, he is brave enough to defend a black man. This trial is very important because it gives an insight of the society people and how they react to Tom’s death. At the end of this trial Jem looses his trust in rationality of the people and sees the irrational evil in people through this ugly incident. When the ladies of the county get together in Finches house, we get to know more about the women of Maycomb. They talk about how their black maids complain and that Jesus never complained so no education will make a â€Å"Christian† out of them. They don’t consider blacks as Christians. After all they believe in the same God. Women discuss and talk but they never really talk about anything that matters.

Jules Verne :: essays research papers

Jules Verne Going to moon, a balloon trip around the world, adventure under the sea, all this in the late 1800s? All this was possible in the writings of Jules Verne. Jules Verne was born in Nantes on February 8, 1828. He had a vivid imagination and as a child, he often sailed down the Loire River with his brother. He always wondered about air and undersea travel. In the 1800s, none of these advances were discovered. His father was a lawyer and wanted young Verne to be one, too. Jules was sent to Paris to study law and while he was there, he became interested in literature. He graduated with a degree in law in 1850. Jules began to write and give private law lessons in Paris. His father voiced some concern in pursuing literature as well as law. When Jules was in his young 20s, he wrote operettas librettos for about 2 years while continuing to practice law. He was appointed as the Secretary of the Theatre Lyrique in Paris. He made some letters to his mother commenting on his shabby clothes compared to the clothes poets there. He started to become a very busy people. Verne was married on January 10, 1857 to Honorine de Viane. He only had 1 child, a boy named Michel, who was born on August 3, 1861. Verne also had 2 stepdaughters, Valentine, and Suzanne. Michel grew up to be a very disobedient child. Verne tried many means of stopping this delinquency. He put Michel in jail in an attempt to stop the "madness". He was really unhappy over his son's behavior problem. Late 1879, Verne ended up throwing Michel out of the house. Michel ran off and married an actress. In 1887, he attended and recognized Michel's second marriage which helped in reviving the relationship between father and son. Jules Verne was an avid traveler and sailor. He visited many places with his brother, Paul. Paul helped Verne in many technical parts of his novel. In 1859, he and Paul made a summer trip to Scotland. Verne was very impressed by Scotland as a whole and it became the setting in one of Verne's novels. He also visited North America for a week. He visited New York, Buffalo, Niagara Falls, Toronto. He loved America and was very sad that he was never going to come again. Verne owned 3 boats, a sailboat, a sailing yacht, and a stem yacht. They were christened Saint-Michel 1, Saint-Michel 2, and Saint-Michel 3, respectively. He loved sailing and visited many place of Europe with his beloved boats.

African Americans health disparities Essay

In 2011, the diagnosis rate for HIV cases in the United States was 15. 8 per 100,000 population and 60. 4 among Blacks. Of 197,090 diagnoses of HIV-infection from 2008- 2011, Blacks/African Americans accounted for: ?47% OF THE TOTAL ?64% OF WOMEN ?66% OF INFECTIONS ATTRIBUTED TO HETEROSEXUAL CONTACT ?67% OF CHILDREN, AGES < 13 In 2010, the death rate for blacks was higher (25. 0 per 100,000) compared with any other racial ethnicity group (3. 0 whites). Blacks represented 49% of all deaths with HIV in 2010. A recent study showed that blacks diagnosed with HIV are less likely than other groups to be linked to care, retained in care, receive antiretroviral treatment and achieve adequate viral suppression. African American Males African American men accounted for 42% of HIV cases diagnosed among men in 2011. A majority (72%) of African American men with HIV contracted the disease by male to male contact while 19% contracted HIV through heterosexual exposure. African American Females Among African American women, high risk heterosexual contact was the most frequently cited mode of transmission, accounting for 89% of cases diagnosed in 2011.

The rate of gonorrhea among blacks in 2010 was 432. 5 cases per 100,000 population, which was 18. 7 times the rate among whites (23. 1). This disparity has changed little in recent years. This disparity was larger for black men (22. 2 times) than for black women (16. 2 times). Chlamydia In 2010, the overall rate among blacks in the United States was 1,167. 5 cases per 100,000, a 4.0% increase from the 2009 rate of 1,122. 2 cases per 100,000. The rate of chlamydia among black women was over seven times the rate among white women (1,536. 5 and 205. 1 per 100,000 women, respectively). The chlamydia rate among black men was almost 11 times the rate among white men (761. 8 and 69. 9 cases per 100,000 men, respectively). Syphilis During 2009–2010, the rate of primary and secondary (P&S) syphilis among blacks decreased 8. 7% (from 18. 4 to 16. 8 cases per 100,000 population). In 2010, 47. 4% of all cases reported to CDC were among blacks and 31. 0% of all cases were among whites. The overall 2010 rate for blacks was eight times the rate for whites, while the 2009 rate was 9. 2 times the rate for whites. In 2010, the rate of P&S syphilis among black men was 7. 1 times the rate among white men; the rate among black women was 21 times the rate among white women. In 2010, the rate of congenital syphilis was 33. 1 cases per 100,000 live births among blacks. Race/ethnicity for cases of congenital syphilis is based on the mother’s race/ethnicity. This rates was 12. 3 times the rate among whites (2. 7 cases per 100,000 live births). More Information: ?STD TOPIC SITE?

There are no certain types of ports for the many different types of computers now days. Port expanders are computer hardware that allows more than one device to be able to connect to a single port on a computer. The two basic types of pot expanders are the internal and the external. I found that there was a girl on this website by the name of â€Å"Cameron head geek†. He is a person that she was able to talk to about the port expanders and at that time he told her that â€Å"Well†¦Ã¢â‚¬ ¦. MAC’s and PC’s have the same ports. FireWire used to be super popular with MAC’s, but a lot of PC’s had it as well.FireWire is pretty much phased out now days though†. Some of the disadvantages to port expanders is a lot of them are external and they can be annoying. They get in the way and could use more power and if your power source is not good enough it could be a real big problem when you add more devices it will take up even more power and then t hat’s not so good. That could cause the computer not to come back on and could also cause you to have to unplug and start all over again. The advantages of using port expanders are that you get more ports more ports to use.SAS expanders take one port and make many out of them. So say you have one 6gbps, and you expand it so you can connect 8 devices. The total throughput on all 8 ports is only 6gbps, or about 80MBPS. Even in regular hard drives can do 80MBPS, so in reality you could see a bottleneck here, but in practice you probably will be fine? In Some cases SAS expanders are cheaper than getting an equal number of â€Å"real† ports. But at the same time it depends on how much you plan on using it and also how much you really want to pay for these items.In this paper I was able to understand the fact that the expander port are not just for using of one type of computer but that they are also able to be used for many different types and that many different types are not just a good thing they have many different types of bad uses also and that sometimes you many think that they are a good thing but at the same time they are a really bad thing. So, all in all they can be good but at the same time they can also be a really bad thing. The information of this paper was found on the website of: www. eugenecomputergeeks. com
