Parkinsons Disease Essays (616 words) - Parkinsons Disease, Medicine
Parkinson's Disease Microbes and Society 03/06/00 Parkinson's Disease Parkinson's disease usually affects people of late middle age. Most run between the age of 50-60. The symptoms of Parkinson's disease are usually subtle and occur gradually. Some examples of symptoms a person may have, are feeling shaky or having trouble getting up from a chair or a couch. Others may notice that their speaking is softer or quieter. They will lose track of a thought or feel irritable or even depressed for no reason. These are early symptoms that may last a long time before the more classic and obvious symptoms appear. For now there is no way to cure or prevent Parkinson's disease from happening., but there has been new research looking at (PET) Position Emission Topography. This will allow scientists to scan the brain, which see chemical change that occurs in the brain. Using PET scientists can study the brain's nerve cells that are affected by disease. IF you are in the major stages of Parkinson's disease the major symptoms are tremors, problems walking, bradykinesia, and rigidity. Rigidity is an increase of stiffness in the muscles. If it is eased by medications, rigidity is always present. It's also responsible for a mask like expression. In some patients it leads to sensations of pain in the arms and shoulders. Secondly, victims with experience bradykinesia, which means slowness of movement. It causes the brains to react slower in its transmission of instructions to parts of the body therefore causing the body to act slowly in carrying them out. Poor balance is often true when victims move abruptly. Some patients experience falls due to poor balance. Last are tremors, they will affect three out of four patients. Tremors may affect only one part or side of the body. For the most part they don't disable people and it disappears during sleep. Some minor symptoms are depression, emotional changes, memory loss, difficulty swallowing, and chewing. At this point there is no cure for Parkinson's disease but there are a wide variety of medications that provide relief for the symptoms. Treatments are determined by how much the symptoms affect the person by a physician. Most of the medications will have to be adjusted to a countable dosage for the patients. In the early stage the physicians begin with one or two less powerful drugs. They saved the most powerful medicines for the time when patients need it the most. One of the most common medicines is Levodopa. Levodopa allows the nerve cells to use it to make dopamine with which the brain can use. It prevents or delays some symptoms in most patients. It also extends the time in which some patients can lead some normal lives. There are some side effects that could happen like nausea, vomiting, low-blood pressure, and restlessness. Symmevel which is used as an anti flu medication but it is also used with Parkinson's patients too. It reduces the symptoms of rigidity. Some other is anthicholinergics, selegiline, and deprehyl. A physician will also strongly suggest that to remain active in the early stages they will tell you to perform daily activities as much as possible. Taking supplements of vitamin E is showed to help somewhat. For the tremors, medication or anything relaxing will sooth them down too. When Parkinson's disease gets in the later stages physicians will help design exercise programs to help meet your specific needs. Last, they will also suggest for you to get a cane or a walker because the patient will be more prone to fall.

Accessing and Managing MS Excel Sheets With Delphi
Accessing and Managing MS Excel Sheets With Delphi This step-by-step guide describes how to connect to Microsoft Excel, retrieve sheet data, and enable editing of the data using the DBGrid. Youll also find a list of the most common errors that might appear in the process, plus how to deal with them. Whats Covered Below: Methods for transferring data between Excel and Delphi. How to connect to Excel with ADOà (ActiveX Data Objects) and Delphi.Creating an Excel spreadsheet editor using Delphi and ADORetrieving the data from Excel. How to reference a table (or range) in an Excel workbook.A discussion on Excel field (column) typesHow to modify Excel sheets: edit, addà and delete rows.Transferring data from a Delphi application to Excel. How to create a worksheet and fill it with custom data from an MS Access database. How to Connect to Microsoft Excel Microsoft Excel is a powerful spreadsheet calculator and data analysis tool. Since rows and columns of an Excel worksheet closely relate to the rows and columns of a database table, many developers find it appropriate to transport their data into an Excel workbook for analysis purposes; and retrieve data back to the application afterwards. The most commonly used approach to data exchange between your application and Excel isà Automation. Automation provides a way to read Excel data using the Excel Object Model to dive into the worksheet, extract its data, and display it inside a grid-like component, namely DBGrid or StringGrid. Automation gives you the greatest flexibility for locating the data in the workbook as well as the ability to format the worksheet and make various settings at run time. To transfer your data to and from Excel without Automation, you can use other methods such as: Write data into a comma-delimited text file, and let Excel parse the file into cellsTransfer data using DDE (Dynamic Data Exchange)Transfer your data to and fromà a worksheet using ADO Data Transfer Using ADO Since Excel is JET OLE DB compliant, you can connect to it with Delphi using ADO (dbGO or AdoExpress) and then retrieve the worksheets data into an ADO dataset by issuing anà SQL queryà (just like you would open a dataset against any database table). In this way, all the methods and features of the ADODataset object are available to process the Excel data. In other words, using the ADO components let you build an application that can use an Excel workbook as the database. Another important fact is that Excel is an out-of-process ActiveX server. ADO runs in-processà and saves the overhead of costly out-of-process calls. When you connect to Excel using ADO, you can only exchange raw data to and from a workbook. An ADO connection cannot be used for sheet formatting or implementing formulas to cells. However, if you transfer your data to a worksheet that is pre-formatted, the format is maintained. After the data is inserted from your application to Excel, you can carry out any conditional formatting using a (pre-recorded) macro in the worksheet. You can connect to Excel using ADO with the two OLE DB Providers that are a part of MDAC: Microsoft Jet OLE DB Provider or Microsoft OLE DB Provider for ODBC Drivers. Well focus on Jet OLE DB Provider, which can be used to access data in Excel workbooks through installable Indexed Sequential Access Method (ISAM) drivers. Tip: See theà Beginners Course to Delphi ADO Database Programmingà if youre new to ADO. The ConnectionString Magic The ConnectionString property tells ADO how to connect to the datasource. The value used for ConnectionString consists of one or more arguments ADO uses to establish the connection. In Delphi, the TADOConnection component encapsulates the ADO connection object; it can be shared by multiple ADO dataset (TADOTable, TADOQuery, etc.) components through their Connection properties. In order to connect to Excel, a valid connection string involves only two additionalà pieces of information -à the full path to the workbook and the Excel file version. A legitimate connection string could look like this: ConnectionString : ProviderMicrosoft.Jet.OLEDB.4.0;Data SourceC:\MyWorkBooks\myDataBook.xls;Extended PropertiesExcel 8.0;; When connecting to an external database format supported by the Jet, the extended properties for the connection needs to be set. In our case, when connecting to an Excel database, extended properties are used to set the Excel file version.à For an Excel95 workbook, this value is Excel 5.0 (without the quotes); use Excel 8.0 for Excel 97, Excel 2000, Excel 2002, and ExcelXP. Important:à You must use the Jet 4.0 Provider since Jet 3.5 does not support the ISAM drivers. If you set the Jet Provider to version 3.5, youll receive the Couldnt find installable ISAM error. Another Jet extended property is HDR. HDRYes means that there is a header row in the range, so the Jet will not include the first row of the selection into the dataset. If HDRNo is specified, then the provider will include the first row of the range (or named range) into the dataset. The first row in a range is considered to be the header row by default (HDRYes). Therefore, if you have column heading, you do not need to specify this value. If you do not have column headings, you need to specify HDRNo. Now that youre all set, this is the part where things become interesting since were now ready for some code. Lets see how to create a simple Excel Spreadsheet editor using Delphi and ADO. Note:à You should proceed even if you lack knowledge on ADO and Jet programming. As youll see, editing an Excel workbook is as simple as editing data from any standard database.

INTERNATIONAL BUSINESS Essay Example | Topics and Well Written Essays - 1750 words
INTERNATIONAL BUSINESS - Essay Example The notion of knowledge management views knowledge as tacit or something which is present in oneââ¬â¢s mind. Human expression and practice compound to the making of knowledge. However, knowledge cannot be enhanced in an isolated state of mind; that is, for knowledge to flourish, information must be enhanced through interaction (Kalkan, 2008). Both explicit and implicit knowledge must be tapped by organizations in order to progress successfully in todayââ¬â¢s globalised world. Knowledge management is, therefore, focused on the attainment of organizational goals and objectives by enhancing the productivity of organizational knowledge in all activities, tasks and programs pertaining to knowledge. The aim is to create and sustain competitive advantage for the firm in the global marketplace by helping organizations exploit untapped knowledge. Hence, knowledge management essentially involves learning through social experiences and interactions. Researchers have broken down knowledge management into four major constructs including the development, manifestation, diffusion and use of knowledge (Kalkan, 2008). It is rather simplistic to think of knowledge management as a linear process in todayââ¬â¢s global village. ... Factors such as geographic dispersion, interaction across different time zones and cross-cultural differences result in increased challenges for the firm (Pawlowski & Bick, 2012). Thus, the global arena has opened a new window for viewing knowledge management which incorporates introductory level, implementation and process issues pertaining to knowledge management (Alavi & Leidner, 2005). Despite increased awareness of these issues, research indicates that most businesses fail to successfully implement global knowledge management (Pawlowski & Bick, 2012). Global knowledge management encompasses all knowledge related activities, tasks, policies and processes that are performed within or between organizations that are globally dispersed. Culture of both the organization and the nation/region plays a vital role here (Holden, 2001). The global environment, therefore, brings with it a host of challenges including those pertaining to humans, organization, management and technology. All hu man interaction and communication (including the dissemination of knowledge) is heavily influenced by culture (Holden, 2001). But perhaps, the greatest of these challenges is to define the very nature of knowledge management itself. Although there have been efforts to differentiate data and information from knowledge, a concrete working definition has not yet been developed in the context of global dynamics (Roberts, 2009). Despite increasing emphasis on knowledge-oriented markets, there has been criticism which calls into existence the very existence of such markets. The absence of a concrete definition questions whether or not these markets actually exist or whether they are ââ¬Å"old wine in a new bottleâ⬠(Roberts, 2009). The term knowledge has become a metaphor rather than a term with

The novel Great Expectations Essay Example for Free
The novel Great Expectations Essay Great Expectations was written by Charles Dickens in the 19th century (1860-1861). It is said to be one of the classics of the English literary heritage and several film adaptations have been made of it. It first appeared in a weekly magazine called All the year round. Great Expectations is a book in which Dickens returned to the theme of a youths discovery of the realities of life. An unknown person provides the young hero, Pip, with money so that Pip can live as a gentleman. Pips pride is shattered when he learns there source of his Great Expectations. Only by revising his values does Pip restore his life on a foundation of empathy rather than on social position. In this coursework I shall be comparing two film versions: David Leans 1944 black and white version starring John Nutts and the 1997 colour version directed by Alfonso Cuaron which features, Ethan Hawke; Gwyneth Paltrow; Anne Bankcroft and Robert Deniro. I intend to compare the opening chapters in the two film versions, in which the young Pip/Finn encounters a scary convict who later becomes a momentous figure in Pips life.Ã Both films start with the adult voice of Pip/Finn reflecting on his childhood. The David Lean (1944) version closely follows the actual text whereas Alfonso Cuarons Version follows a sequential order but digresses greatly from the text. As the credits began rolling there are a variety of styles of music. The first style that we hear is a full orchestra and it then harrows down to only one flute which plays a childish style of music which is obviously representing the young PIP. Afterwards it goes into a romantic mood and after that a sad mood. It finally becomes a symphony of emotion to signify the films happy ever after ending. In the opening scene we start with a long shot of Pip and the tracking of pip across the field. At the camera is tracking Pip we see many images of death, for example as Pip is running the audience see a number of Jibbets. As Pip is running the audience is able to see how closely David Lean has followed the text. The marshes are seen to be just a long black horizontal line and the river a long horizontal line but not much thicker. The sky is also just a row of angry red lines and dense black ones. The camera again zooms in on Pips face to show us his apprehension as he climbs over the wall. The audience is able to see many gravestones are crooked and a lot of plants and weeds are overgrown. This suggests that this churchyard is uncared for. This adds tension to the opening scene because we wonder why this young child is there. All throughout the opening scene there is wind sound affects. The wind is an eerie sound which also adds to the tension of the scene. When I was watching Pip I felt a lot of sympathy because I had seen from the gravestone that both of his parents had died and learned that his only relative was his sister who he lived with and she wasnt exactly a ray of sunshine. Alfonso Cuarons version also starts with the credits first which is unusual for a modern day film. As the credits begin there is soft music with very exotic instruments such as a rainpie. The letters of peoples names appears in a fluid pattern, which gives us a watery feeling. This s a good technique as it sets the audience up for the opening scene where things are not necessarily as they seem. The first thing the audience sees is the character of Finn Pip) looking at the fish and then climbing into the boat. Finn takes out a notebook and begins to draw. At this point there is virtually no tension as there is an ordinary boy who is playing in the sunshine and frankly looks quite happy. There is none of the heart tugging emotion that is apparent in Leans black and white version. Finn then climbs out of his boat and carries on looking for more fish to draw. All of a sudden there is a big cloud of red forming underneath the water then a hand comes out of the water and grabs Finn and we realise that this is the convict. This method is more effective than Leans version because it is so unexpected; there is virtually no tension at all up to this point. Whereas Leans version builds the tension up so high that we actually expect something to happen to PIP. I assume that David Lean directed his film as he did in order to retain the essential authenticity of the book. This was important for Lean to do because the book has a way of taking you out of your own reality and this was what the people of 1944 needed to get away from the Second World War. Whilst the 1997 version is not trying to reproduce a historical piece- it is a modern version of the plot transposed to America. I believe that Cuaron did this in order to make the film more realistic, so that the audience could feel that this can happen to anybody. In doing this Cuaron lost the essence of the plot, with its fairytale ending. The similarity that I have seen in the two films is the contrast of Pip/Finn compared to the convict. The directors are both trying to balance Pip/Finns innocence compared to the convicts corruption. Lean does this by keeping Pip polite and sincere all the time while the convict is strangling and pushing him etc. Cuaron does this by making the convict swear to scare Finn; I feel that Cuaron does this because he thinks he needs to do more to shock the modern day. The main differences between the two versions are the location, setting and background. For example Cuarons version had an American actor doing Finns voiceover, it took away some of the reality of the film because I feel that Great Expectations is so typically English. I can agree to some extent that both films had a strong opening which is essential in a film. The reason for this is because if there is a weak opening t the film you will not want to watch the rest of it; the same when reading a book if the first few chapters are not engaging you will not want to finish the book. Generally I preferred David Leans version because it kept to the book. Maybe I might have differently if I hadnt read the book first, but the 1997 version deviated from the book so much that I was confused which character was meant to be which. Lea I felt was also much more effective in setting up the story. Although both films id follow a chronological order, David Leans 1944 version kept very closely to the text where as the coloured version altered the location and dialogue of the novel.Ã David Lean built up the tension first using sound effects I.e. wind and bustling trees, the dreariness of the marshes and using the numerous visions of death I.e. the jibbet and the crooked gravestones.

Cell Phone Technology :: Technology Communication Phones Essays
Cell Phone Technology Ring ring! All the people in a 20-foot-radius are thinking it is them that are ringing. Women search through their purses; men reach for their pockets to see if it is their cell phone that is ringing. The year is 2002, and it appears that almost everyone has a cellular telephone. Many believe that in today's society it is a necessity to own one and would be difficult to go a day without one. Are they really necessary? People survived just fine without them before their invention. It really was not until about 15 years ago that they really started appearing and the last five that it seemed as if every Tom, Dick, and Harry owned one. What has caused their sudden boom? Are people becoming too reliant upon them? Is there health risks involved when people send such powerful signals directly toward their heads? Cell phone technology dates all the way back to 1947. ââ¬Å"In that year researchers first developed ideas as to the possibility of creating mobile phones that used "cells" that would identify a user in whatever specific region he or she was initiating the call fromâ⬠(Cell Phone World). Still the technology was very limited at the time, so much more extensive research was required. In 1968 private companies started getting involved with cell phone development, such as AT&T. The FCC (The Federal Communications Commission) then opened new frequencies and the private companies had the theory of cellular towers. Each tower would be responsible for a particular region. When a customer traveled farther a way from one region it would switch the call to a closer tower with no interruption. In 1977 public cell phone testing had begun. People in Baltimore, Chicago, and Washington were the first to be eligible for cell phone trials. In 1979 a company in Japan began doing cell phone testi ng with the public. Not until 1983 were cell phones really available. ââ¬Å"The year 1988 changed many of the technologies that had become standard in the past. The Cellular Technology Industry Association was created to set realistic goals for cellular phone providers and research new applications for cell phone developmentâ⬠(Cell Phone World). In a way they still were not very accessible to the public, due to their extremely high operating cost to the consumer. Only the very wealthy could afford cell phones. Important heads of cooperationââ¬â¢s, movie stars, and top government officials were able to afford the luxury of a mobile phone.
