Iconostasis Essay Example | Topics and Well Written Essays - 1000 words
Iconostasis - Essay Example ... This arrangement, however, differs in the finer churches in Greece, Russia, Turkey and the East where the iconostasis is adorned with a wealth of paintings. In those churches, aside from the two requisite pictures, the iconostasis is covered with pictures throughout. On the royal door, there is always the Annunciation. The Annunciation is the revelation made by the archangel Gabriel to Mary, the mother of Jesus indicating that she would conceive a child, the Son of God. In addition to the Annunciation there is often a depiction of the four Evangelists. On each of the other doors there are generally pictures of St. Michael and the archangel Gabriel. Beyond the deacon's door there is usually the saint to whom the church is dedicated. Additionally, at the opposite end there is either a picture of St. Nicholas of Myra or that of St. John the Baptist. Depicted above the royal door, there is a picture of the Last Supper and directly above that picture there is often a large picture of Jesu s sitting on his throne with a crown and adorned in priestly clothing much in the image of a High-priest. At the pinnacle of the iconostasis there is a large crucifix which represents the source of salvation for believers and on either side of it, there are pictures of the Virgin Mary and St. John (Wikipedia, n.d.). In extremely elaborate iconostasis, the pictures are arranged in rows across the entire length of the iconostasis. The bottommost row contains the pictures previously described while the second row generally contains pictures commemorating the fundamental feasts of the Church such as the Nativity, Annunciation and Transfiguration. The third row generally contain pictures of the Prophets of the Old

Ethics and Professional Responsibilities Essay Example | Topics and Well Written Essays - 250 words
Ethics and Professional Responsibilities - Essay Example This is because they may result in to severe consequences if not well checked. Therefore the moral obligation to consider the consequences of their actions or decisions lies with the engineers themselves. Whenever a safety problem occurs or during a disaster recovery, any concern noted by engineers should get reported to the relevant authority to enable investigation and subsequent response to the problem. This has often been a challenge especially when one feels they may be blacklisted or fired. However, it is ethical and moral standards that an individual engineer has that will bring a difference when such situations arise (Jr, Pritchard, Rabins, James, & Englehardt, 2013). When an issue of concern is not reported due to fear of having oneââ¬â¢s job in the line, the consequences that may arise could be very dire not only to those in the surrounding but also to the engineers who engage in the given activity. Therefore, it is important for engineering students to have ethics as a part of the curriculum so that they are prepared to make decisive decisions in their professional careers. This will enable presentation of code of ethics to the profession of engineers saving the world from the unforeseen misfortunes that may result from unethical practices in this profession ( Jr, Pritchard, Rabins, James, & Englehardt,
Chattel Slavery Essay Example for Free
Chattel Slavery Essay Indentureship was supposed to differ from slavery, however, the servants were treated as harshly as the slaves Chattel- African slaves were treated as commodities System of slavery whereby an individual and their offspring are recognised by the law as being the property of another person for life. This system was established by Europeans and formed the basis of transatlantic slavery With due respect to the Is good intentions, from all that I have read and studied it would be a mockery to compare Indian indentureship to African chattel slavery in the Caribbean. Firstly, Indians were allowed to retain: their family (Africans had theirs split up); their language (Africans had the use of theirs forbidden); their religion (Africans had theirs banned); their music (Africans had the drum representing the voice of their gods banned by laws, some of which remain on the statute book in Barbados to this day). This highlights the all-important difference between indentureship and slavery: The heart of slavery was not the horrible labour conditions. If that were so, slavery and indentureship might be comparable. The heart of slavery was the stealing of the Africans soul his language (the eyes through which one sees the world), his gods, his family, his musical sounds. That is why some 169 years after Emancipation, many Africans in the Caribbean remain enslaved. Some say enslaved mentally (in distinction to physical slavery), but this is misleading. SLAVERY IS MENTAL. Captivity is physical. Why the Africans have taken longer to restore their race as opposed to Indians, Jews and other ethnic groups that suffered at the hands of White Supremacy is because no other people were ever subjected to what the Africans suffered. If you capture a people and reduce them to harsh, brutal conditions of exploitation, once they survive, when that is brought to an end the people will soon rehabilitate themselves. But when you take away a peoples tongue, their connection to the ancestors, their gods; when you smash their family life so that the male loses respect for the female and vice versa; when you teach them to hate their skin, their lips, their hair, so that they hate anyone that looks like them then you will have destroyed the culture and soul of that people and recovery will be almost like a resurrection. That is why it has taken Rastafari, Vodun, Orisha and the other spiritual potencies to awaken and heal the descendants of the African slaves. Secondly, millions of Africans died on the dreadful crossing from Africa. How many Indians perished on their way here? The Trans-Atlantic trade in captive Africans and African chattel slavery lasted roughly from 1473 to the 1880s some four centuries. Indian indentureship lasted from the 1840s until when the end of the 19th century? Thirdly, the trade in African captives depleted the African homeland tremendously. Consequently, up to this day, in contrast to the huge populations of India and China, the African continent is badly underpopulated. In fact, it has been estimated that even if all the Black people returned tomorrow to Africa, it still would not be fully populated. Walter Rodney in à provides some Statistics to give an idea of the devastating effect that the trade in Africans had on Africa for four centuries. Whole towns and villages were wiped out. Ethnic groups disappeared. Others were driven to war on their neighbours or face the prospect of having their own group captured and shipped to the New World. The natural line and trajectory of material and spiritual development for millennia in Africas history up to the time of the Trans-Atlantic Trade in captive African was interrupted, disrupted and corrupted. While it is true that India suffered horribly as a result of the British penetration of India during the period of indentureship, history attests that neither the scale nor the time period of this penetration can match the reality of the impact of the Slave Trade and Slavery on Africans and their Motherland. But while the enslaved Africans unlike the indentured Indians had their ancestral cloak ripped from them, the White man could not take the living nucleus of their culture and its memory from them. So (as they say whoever loses his life shall gain it) they took this breath of their culture and created the living soul of Africa in the Caribbean they recreated their musical forms, they reconceived their ancient gods through new prisms (likje Judedo-Christianity, for example in Haitian Vodun and Rastafari), they revived their sense of an organic connection to the earth, they rediscovered the taste of their traditional cuisine, and so on. And that is why we find that almost all that is distinctive about indigenous Caribbean culture owes its inspiration, its image and likeness, to Africa. It is also probably why there is no enduring large-scale mass Back to India or Back to China movements coming out of the Caribbean. In a sense, Mother India and Mother China were not taken away from their indentured children in the Caribbean since they continued to wear their traditional dress, listen to their traditional music, speak their traditional language and worship ther traditional gods. When the true history of the last 5 centuries of the recently past millennium is finally placed in proper perspective, the incomparable tragedy of the African people during the era of the slave trade and slavery will come fully to light. It is without precedent in human history. I close by suggesting that the Indian people who are essentially of African origin as Rashidi has documented have a secure place in Rastafari, and as the Mansinghs have shown in their research, they have made a valuable contribution to the development of the Rastafari way of life. Indentured servants were working on contract to repay a debt, usually for transportation to America. Chattel means personal property, so chattel slaves were legally considered property, the same as a mule or a goat. An indentured servant worked for his/her master without pay until the debt was paid off. Typically, for repayment of the cost of being taken from England to America, the time of service was seven years, although it ranged from four to ten. At the end of that time, the indentured servant was free to leave and find other, gainful employment. There were cases of abuse by masters in which additional time was added by charging the servant for things like rent, food, lost or broken tools or products, etc. , because indentured servants were usually not well-educated and could be taken advantage of. The only ways a chattel slave could be released from a lifetime of unpaid service were manumission (being legally given freedom by his/her owner) or purchase, either by himself/herself rare, but possible or by a third party, such as societies of abolitionists who purchased slaves freedom for them. The best-known of these groups bought land in west Africa and founded there the nation of Liberia, for the purpose of resettling freed American slaves. Interesting sidelight: the term indentured is related to words like dentist and dental. An indentured servant had a written contract with his master. At the time the contract was signed, it was torn in two. The master kept one half and the servant kept one half. To ensure that these halves were part of the original document, the tear-lines were deliberately made irregular and jagged so that no other piece of paper would match. The jagged tearing was indented it looked like teeth

Computerised Stock Control System
Computerised Stock Control System Introduction The Enterprise Networking assignment is based on the computerised stock control system. This assignment is about how to implement a new online book company called ââ¬Å"Amazing Booksâ⬠. ââ¬Å"Amazing Booksâ⬠company is a new online book company that will be selling books via a website. The website represents the books that are in the companyââ¬â¢s warehouse. It also contains the information of the books and the information provided to the customers to order the books they want. It is linking with companyââ¬â¢s stock control system. The stock will be regularly recorded and updated based upon the sales record. When a customer fills an order form, he or she has to choose the items and the delivery information. When the company receives the order, it delivered the packaged books to the local depot of a courier company. The online book company also implements its computerised inventory control system in the warehouse. This system includes order processing, recording new entry of books, despatching books to the courier firm, and flagging stock reorder levels up. So, the company will investigate the websites of stock control system as sample and implement its own one. Besides, the company will create a local area network (LAN) for in the warehouse by using appropriate media and topology to carry out its processes well. The company also has a plan to deliver the ordered stock items from the warehouse to the delivery company successfully by using suitable vehicles which contains hardware and software for security management. The last plan is to manage a security control system in order to prevent the theft of staff themselves and to regulate the stock reorder level by the time theft occurs. The network administrator or manager of the ââ¬Å"Amazing Booksâ⬠online book company will be investigating the book websites and computerised stock control system websites of other companies. He or she is also looking forward to finding the delivery management system and security management system on the web. Then he or she will be writing a report (with recommendations) how to implement theirs company in order to successfully set up. Task 1 Amazing Books Company is one that wants to manage themselves as an online book sales company. They will sell their books via the internet. So, they want to develop a website which will display information about their books. Before it is developed, they examine three websites of the online book companies that sell theirs via the internet. The first investigated website is www.bookshopofindia.com. In home page, the pictures of some books are presented. When the pictures are doubled-clicked, the summaries of each book are displayed. It contains other information such as authorsââ¬â¢ names, ISBN number, price and numbers of pages. On the left-hand side of the home page, the subjects of the books that are sold in this website are listed. The subjects contain religions, arts, commerce, computer technology, children books and so on. To order the books, customers can send e-mails, but they can only make payment by using bank account of Corporation bank and Punjab bank. The second examined website is www.boomerangbooks.com. In home page, some pictures of normal books are placed on the right side. In the top, some special ones such as books for Motherââ¬â¢s day are put. In the middle of the page, some are advertised by showing pictures, authorsââ¬â¢ names, and short descriptions of them. If the pictures are double-clicked to investigate, the pictures of the booksââ¬â¢ covers and summaries of them with authorsââ¬â¢ names appear. ISBN, format, number of pages, publishers, publish date and languages are also shown. On the right side, normal price and discount price are compared. On the left side of the home page, the site arranges some categories to browse for books according to book categories, bestsellers, books from movies, and book awards, etc. It also places book contents. In home page, it ranges a menu called ââ¬Å"Boomerang Books Bulletinâ⬠. If a user signs up in this form, he or she can get a $5 book voucher and 20% discount when discounts days are on. To order the books, the site displays its phone number, e-mail address, and fax number. Thus, customers can order by phone, e-mail or fax but they can pay only Australian dollars. The third one that is observed to get displaying books information is www.cherrythitsar.org . This website is the one where users can get e-books. On the home page, there is a list that describes the categories that users can download. These categories contain Myanmar free e-books, Myanmar novels, Myanmar newspapers and so on. If a customer wants to get them, he or she has to make an account by entering user name and password. Then he or she can get them. After investigating these websites that provide information for online book selling, ââ¬Å"Amazing Booksâ⬠, the online book company, is implementing their website. On the top of the home page, the photos of the books that are sold for the memorial days will be presented. They will be sold by gifting suitable discounts. On the left-hand side of the home page, the catalogues of the books will be exhibited in order to search books by the categories the customers want. The catalogues will queue the lists of the books according to book categories, bestsellers, books from movies, and book awards, etc. If the photos of the books in home page are double-clicked, the summaries of the books with booksââ¬â¢ titles, sorts of books, ISBNs, authorsââ¬â¢ names, publishers, publishing date, number of editions, and number of pages, etc. will be shown. Under the every page of site, there will be companyââ¬â¢s address and ordering information will situate. Ordering information will include phone numbers, fax numbers and companyââ¬â¢s e-mail address. So, customers can order books by ringing a phone call, or making order by fax, or sending an e-mail. To order by e-mail customers must fill chosen items into the shopping basket that is on the right side of the home page. Then they have to enter their phone numbers and addresses (including postal code). They can enter their bank accounts or credit card accounts to order. Task 2 There are many stock items that are stored in the warehouse of the ââ¬Å"Amazing Booksâ⬠online book store. The stock control system in warehouse is linked with the companyââ¬â¢s website so customers can view the books that are in warehouse via the website. If they want to order books, the will their personal information including delivery addresses, postal codes and bank or credit accounts. When customers make books order via website, the company will inform the staff of the warehouse. The warehouse staff checks the level of stock items and reply to the main server. And the server keeps the information update and let the customers know information to the website. Then the company will deliver the books to a delivery team. And then the courier company will deliver books according to the customersââ¬â¢ addresses and postal codes. To carry out these processes successfully, the book store needs a proper inventory control system. So, they gather information for stock control system by exploring the websites which represent their computerised stock control systems. Required information for recommendations The first and second investigated websites show their online stock control systems. They show their product information and other associated one. Customers can search and browse they want and they can order them by e-mails. The company that creates the first website is using RFID (Radio Frequency Identification) readers for recording the new items for the stock. The company also explains its delivery service for ordered items. The second website uses barcode reader. It describes their control system of balance levels of the stock and alerting the flagging up reorder system by using the stock control management software. The third and the fourth one are the websites that sell software applications for computerised inventory control management system. They give the detailed information of how to use their software. Both of them are produced to run the functions of recording customersââ¬â¢ order, purchasing, items entry, auditing, receiving, shipping, transferring, reporting and security management, etc. Among them, the former one is used with barcode reader and the latter one with RFID for recording new stock items for the system. Customers can buy their software by entering their e-mail addresses, and bank or credit account numbers in these websites Methods and hardware for recording stock entry which are in warehouse After investigating four websites, ââ¬Å"Amazing Booksâ⬠implements its computerised stock control system. First of all, they make purchasing books from many other sources. Then the books are put in containers which contain RFID (Radio Frequency Identification) tags and the containers are carried by suitable vehicles. When they arrived to the warehouse of the company, the RFID tags are checked by RFID readers which transmit the series of digital identities of the books wirelessly. The tag readers detect the packages or containers which contains several book items. The RFID readers can check each entire container simultaneously and enter data into the server computer using special stock control management software for inventory control. So, the right data in database of the server can keep updating. Being linked the server with the website of the company, the information of the books in web pages is automatically updated. (c) Methods and hardware for order processing To order the book items, the customers have to fill the order form. In this form, the customers must fill their information that contains their addresses and postal codes and delivery fees (which price ranges depend on countries) by means of bank or credit account numbers. After that, they can order books via website of the company. When the company receives orders from customers, they register information of customers and orders in Order file. They check concerned master and transaction files to know how many numbers of which stock items are ordered. They also interrogate stock levels in the warehouse using RFID readers and make records of sending items. These records are entered into the server to update stock information. They then display that information in the website that is linked with server of the company. So, customers can see whether their ordered items are sent to them or not. (d) Methods and hardware for recording despatched items Their next procedure is to deliver the ordered books to a local courier company. Before they send, they pick books up from the warehouse and pack them into specific packages or containers which consist of RFID tags which will help the courier firm easy to check them. Then they deliver them to the delivery firms by appropriate vehicles. When the books arrive, the courier companies check the RFID tags of packages or containers by using RFID readers. Then they start delivering them to the customers around the world by using flights or ships or other appropriate vehicles. The delivery firm company sends the items information in order to update data in database of the server of delivery company. They will update the delivery information whenever the items arrive to their braches in different countries until they reach to the destinations. So, the customers can view the information on the website when and where their ordered items are arrived. (e) Flagging up and reorder levels of stock items After sending the ordered item, the website needs to update the item information. To make balance for the reorder level, they use the automatic flagging up system using the stock control software by giving notation on the server of the warehouse. So, the company can check balance level and decide whether they should reorder new books from other sources or not. (f) Required hardware for system To complete the system, they also use some kinds of hardware devices. They use Server for the main control processes for the stock. And they also need to use some kinds of not only security devices for the warehouse security but also special software to control the system and to prevent unauthorized access to data. It describes their balance of the stock and alert the flagging up reorder system buy using stock control software. Task 3 To implement the computerised stock control system used in warehouse the local area network (LAN) is conducted. The major requirements of LAN network are topologies and media. There are many topologies though only some are widely used. The most popular topologies are ring, bus and star topologies. In ring topologies, computers are connected by cables in a circle or ring form. Each computer is directly connected to the next, so no termination is required. In this topology, token passing method is used to transmit data in clock-wise direction. So every computer can transmit data fairly. It can prevent high-traffic and time-critical applications. So it is reliable and highly secure. But it uses fiber optic cables so cost is high and finds difficulties to install. In bus topology all computers are connected via a backbone, a cable segment. In bus topology, signals are sent as electrical parses. When they are sent, they travel along the cable in all directions. So, data collisions can occur when more than one computer transmit data simultaneously. Thus, occupying high-traffic is the major problem; otherwise, cheapness and ease of installation are advantages. In star topology, all components are connected by cable segments to a central device to communicate each other via it. It can share network resources and send and receive data from the computers in the network simultaneously because it handles multiple connections. So it is useful where high traffic occurs. It supports centralized management and the central server has a complete priority over other computers. But this topology requires a more involved cable installation and high cost. The access of the entire network also loses when the central device fails. To build a network we also need media. There are two groups of media; bounded and unbounded media. In bounded media, there are three types of cables; coaxial cable, twisted pair cable, and fiber-optic cable. Coaxial cable consists of two kinds- thin coaxial (10 Base2) and thick coaxial (10 Base5). There are two types of twisted pair cables; unshielded twisted pair cable (UTP) and shielded twisted pair cable (STP). The optical fiber cable contains two kinds; glass and plastic. The unbounded media or wireless connection technology contains Wi-Fi, and Wi-Max connection. Wi-Fi includes 802.11b and 802.11g at 2.4 GHz frequency and its speeds are between 11 Mbps and 54 Mbps, and 802.11a and 802.11n has 5 GHz frequency and 54 Mbps bandwidth. There are two versions of Wi-Max connection fixed Wi-Max (802.16-2004) and mobile Wi-Max (802.16e). The stock levels displayed in the website are based upon the sales figures which are in warehouse. Updating stock control system regularly can help the stock level. To support the stock control system a LAN network will be created in the warehouse. There are two types of networks; peer-to-peer one and server-based one. The server based LAN network is chosen to implement as it can handle a number of computers, more memory for a large database and extra peripheral devices such as printers; otherwise, peer-to-peer network can handle 10 or fewer workstations. To configure a server-based network, an appropriate topology and a suitable medium are used. The proper one for this network is star topology. Using central devices such as switches connected with cable segments, it supports centralized management for the entire network. It shares resources and access to clients simultaneously without traffic. Unshielded twisted pair cable is used as medium. It ranges into seven categories. Among them, category 5 is chosen because it is designed for 10 Mbps Ethernet whose speed is up to 1 gigabit. It can connect even 1024 nodes and can run 100 meters distance. It also provides ease of trouble shooting all nodes of the network. After configuring topology and medium, a server-based LAN is implemented. Firstly, the OSs is installed in the server computer. Then Active Directory Service (AD) is installed. So, it becomes a domain server which can control client nodes in the workgroup. There will be a network administrator as the authorized user of the server computer. This administrator will control security, access and user accounts of each client-computer user. Being centralized managed network, only server one can share resources but the client cannot. Data can only be updated, or deleted by the administrator who uses the server computer and not by the client. Thus the administrator can check and control the database using the information reported by clerks who provide data concerned with sales figures. Therefore, this database can offer up-to-date information for the stock control system because it is based on the sales figures. The computerized stock control system is being linked with the website via internet. So, regularly updating the data of the stock control system means the website shows the information deal with the status of the books items that are in ware-house. This makes customers easy to find the information they want and to order books by filling order form that displayed in companyââ¬â¢s website. Task 4 The company will inform the staff of the warehouse about the information of the ordered books when they received confirmed orders and cost by bank or credit account from customers via their website. They also acknowledge the customers about the confirmation. The voucher numbers of the ordered books and the DNS of the courierââ¬â¢s website are also given. Processing Order in Warehouse After receiving the ordered report, the staff members in the warehouse prepare to deliver the stock items. First of all, they check to ensure whether the quantity of the stock level is complete or not. Then they prepare to send them to the local delivery company. They firstly put and pack the books by means of ordered quantity and titles in the packages or containers. Then they fix an RFID tag which contains an electronic serial number on each container. The information of the sent items is marked by means of an RFID reader which can detect the electronic signals of serial numbers of the books. Then the information is transferred into the server computer to update the data in database. Transferring stock to local courier company Then they transfer containers of books to the local courier firm by taking suitable vehicles which are fitted GPS (Global Position Service) system to point the routes and time taken of them and to acknowledge the company what time where they are. When the containers of books arrive to the delivery team, they are checked with RFID readers again to mark what time the delivery items are received. It makes ensure not only the stocks are prevented by theft of staff but also they are safely arrived and whether they are the correct ones or not. Delivering stocks by Courier Company The delivery team starts the delivered items entry into their website after checking them. Along the paths of wherever they deliver the stock until they reach to the destination, they regularly update information on their website. So, customers can check the delivery information via the website of the courier company if they want to track about their ordered booksââ¬â¢ information. The delivery company delivers the ordered stock items according to the customersââ¬â¢ addresses and postal codes. If the addresses and postal codes indicate a customer is in local, the company uses cars to transport them. Otherwise, they firstly send by using shipping delivery to the foreign countries where the branches of their company are situated and they send to their destination addresses and postal codes at last. Updating data Each branch of the courier firm also reports to their main office and the office also return the information to the ââ¬Å"Amazing Booksâ⬠company until the ordered book items are received by the customers. The online book store company also updated the information in their companyââ¬â¢s database in main server. Being linked with the server of the courier company, the information of the books in their website is also updated. So, the customers can see where the items they have ordered and when they will receive them by entering the voucher numbers of them on the website of the courier company. After the ordered books are transferred from the delivery company to the customers, the firm also reports to their main office again. The main office of the company also replies to the online book store company. And then the book store renews the data in database of the server in order to check the balance stock levels by means of automatically flagging up system. Task 5 ââ¬Å"Amazing Booksâ⬠online book company keeps in a large amount of book items in the companyââ¬â¢s warehouse. The stock items in the warehouse are kept by staff members of its. To secure the warehouse and the books in it, a security management system is needed. This system is also required to prevent unauthorized access data of the company. The company should also think about the theft or access data without permission done by staff members of the company themselves. (a) Methods to prevent theft and monitor the staff To implement the security management system of the warehouse, both hardware and software are needed. At first, the local area network (LAN) will be created using Star topology to control the centralized management of the companyââ¬â¢s LAN network. Furthermore, the network administrator should also manage the specific working hours, authorized access, and login passwords, etc of an individual staff. So, unauthorized access that aims getting companyââ¬â¢s important data in database of the server dishonestly can be overcome. It can also prevent the fraud of staff. Moreover, there should be some plans to detect and prevent the theft of stock items in warehouse. The most appropriate thing to monitor inside the warehouse is CCTV cameras. They will let the administrator or manager watch inside the warehouse all the time. He or she can immediately know if theft is occurred. Besides, there should be some limitations at the entrance and exit of the warehouse. Using retina scanner at the entrance is a proper method. The scanner will sense the retina of each staff to separate if the person has the permission to enter into the warehouse or not. It will make the record of each and it will alarm if something doubtful is happened. An EAS (Electronic Article Surveillance) should be fixed at the exit of the warehouse and everybody must be through when they leave the warehouse. It will detect each person using radio frequency technology and alarm when the staff takes the book items out without registering for despatched processes. (b) Adjusting the stock levels when theft occurs Before implementing the security management system of the warehouse, the stock levels of the books should be checked to ensure that the quantity of the stock before they are stored in it. When the books which are bought from different sources arrive to the warehouse, they are checked with RFID readers. Then the information of the books is transferred into the server computer as unique serial numbers of each. This event makes update the data in database. The server then stores the information of the books which includes quantity, booksââ¬â¢ titles, and ISBN, etc. When the books are delivered, they are packed in containers which have an RFID tag and are rechecked with RFID readers again. Then checked data and data in database of the server are compared to confirm. If they are not same, the administrator can know the books are thieved by staff and he or she should review the security records. Automatic flagging up system also alerts when the quantity of books are less to acknowledge the administrator. So the administrator can check the balance level of the stocks and reorder new books from sources if necessary. Task 6 The report is produced in order to describe the recommendations of how to set up the computerised stock control system of the ââ¬Å"Amazing Booksâ⬠online books company. The summarising reviews for each procedure are as follows: Reviewing Task 1 The company investigates three online books websites via internet. They examine the features of the websites in details, i. e, the presentations of the books, selling and order information, delivery information, and discount information, etc. Then they will implement their own by using the facts which are based on the recommendations. Reviewing Task 2 The company explores four computerised stock control system websites. Then they set up their own computerised inventory control system in the large warehouse of the company. First of all, they will record the stock information by using RFID readers when the stocks arrive to the warehouse. Then they will transfer that information to the database of the server of the warehouse in order to update the data. The information in website will also keep updating because it is linked with the server of the company. When customers want to order books via website, they have to fill the order forms which contain the information deal with their addresses, postal codes, and bank or credit card account number. Then they will transfer the stocks to local courier company by appropriate vehicles. After that, they will update the information of books delivered in database of the server again. In the warehouse of the company, there will be an automatically flagging up system. They will fix this system to auto check the balance level and quantity of the stock. It will alert the company when the new stocks should be reordered. Reviewing Task 3 As the third step to implement the companyââ¬â¢s stock control system, they will create a local area network (LAN) in the warehouse using suitable media and topology. The LAN will be set up as a server based one in order to centralized manage the whole network. The website of the company will be linked with the server so the information in website will always keep updating. Reviewing Task 4 After receiving the containers that contain books, the courier company will check stocksââ¬â¢ RFID tags with RFID readers and make records the books information. This information will be transferred into their companyââ¬â¢s server computer to update data in database. As it is also linked with the website of their company, the delivery information will also update. The delivery company will always update the delivery information whenever the stocks arrive to their branches which are in foreign country. They will keep updating until they reach to their destination addresses. Customers can view what time at where their ordered books are via the website of the courier company. Reviewing Task 5 There will also be a plan to prevent thefts done by staff while the company is setting up their online book selling system and computerised stock control system. To prevent those events, the administrator will monitor the staff by using CCTV cameras. He or she will also use retina scanner at the entrance and EAS (Electronic Article Surveillance) system at the exit of the warehouse. To prevent unauthorized access, the administrator will manage the specific working hours, authorized access, and login passwords, etc of an each staff member. The stock levels are record by RFID readers when they reached to the warehouse. That information will be transferred into server of the warehouse. When the books are delivered to the deliver firm, they are rechecked with RFID readers again and transferred into server in order to update the data of stock levels. There will be an automatic flagging up system to alarm to acknowledge the administrator. So the administrator can check the balance level of the stocks and reorder new books from sources.

The Political And Econimical C :: essays research papers
The Political and Economical Causes of the American Revolution The revolution began after many years of unrest between England and the American colonies. England's taxes, tariffs and new acts, imposed greatly upon the new American people. Large tariffs were placed on non British imports. British goods were more expensive, but they did not carry the high taxes that were imposed on foreign goods so they seemed economical. However British goods were of a lower quality than the foreign goods which made them difficult to sell. Unfortunately the American people depended on England and other nations for all modern commodities because they had not yet set up factories to manufacture their own. The English took advantage of this fact in every way possible. It was their thirst for political power and domination over the American economy that sealed their fate. England passed many acts to entice the Americans into buying their goods. One of the first to be passed was the Molasses Act of 1733. This act stated that molasses coming from the French or Dutch sugar islands was to have on it a six pence tariff per gallon. Instead of encouraging people to buy British molasses this act bred dishonesty. Merchants, who distilled the molasses to make rum, claimed that the British suppliers could not meet their needs. The merchants then began bribing the customs agents to wave the tariffs. Many agents pocketed extra money that way. A man by the name of Grenville observed this and created an act, The Revenue Act, which was successful with Parliament. This act stated that the tax on molasses would decrease to a mere three pence tariff per gallon of molasses. After the instatement of this act Grenville put an end to the bribes. The next act was the Currency Act of 1764. This act stopped the colonies from manufacturing their own money for trade with the British. This act was followed by the Quartering Act of 1765. The Quartering Act forced colonies to provide troupes stationed in their area with housing accommodations. This imposed greatly on the people, soldiers stayed for months and with an extra mouth to feed and little financial aid times became rough. The Stamp Act, passed in 1765 was one of the "straws that broke the camels back". This act required that such documents as college diplomas, dice, legal documents, customs papers, playing cards, almanacs, and newspapers had to have a special government stamp that showed that they had been properly taxed.

Blood Brain Barrier Essay -- Biology
The brain is permeated by a vast network of tiny blood vessels called capillaries- so tiny and thin that blood cells have to pass through in single file. In the brain alone there are enough capillaries that if you laid them all out end to end they would stretch from Tucson to Tijuana. These capillaries are surrounded by a single layer of cells. That layer of cells forms a barrier between the capillaries and the cells and fluid of the brain. These barrier-forming cells are called "endothelial cells". You can think of "endothelial" as a synonym for "lining" or even just "barrier". When we use the phrase Blood Brain Barrier, (which for obvious reasons we'll refer to as BBB from here on out!), we're talking about all of these endothelial ("barrier") cells collectively. Function of the BBB The cell membranes of the BBB contain transport proteins. If the brain is a nightclub, the transport proteins are bouncers. They decide who gets in, and who gets kicked out. On this website we'll be introducing you to the most important transport proteins- OATP, MDR1, and MDR2. Don't let all the acronyms intimidate you- read carefully and you'll be fine. If the nightclub/bouncer analogy doesn't work for you, you could also think of them as little vacuum pumps and blowers. An extremely detailed view of their actual mechanisms is beyond current knowledge. Importance of the BBB Without the BBB, undesirable molecules could freely diffuse from the capillaries to the fluid that surrounds the brain cells. These undesirable molecules include: TOXINS- poisons taken in from the environment. IONS- that might upset the delicate electrochemical gradients of the cerebral fluid. ACIDS and BASES- that might upset the cerebral ... ...aks down the BBB, so the mice infected with GBS lacking this toxin developed less bacterial meningitis than those infected with the normal GBS. -Doran says: Ãâââ¬Å"These findings demonstrate a novel function of the blood-brain barrier, to act as a sentry that detects the threat of a bacterial pathogen and responds by triggering an immune response to clear the infection. 3. Neuwalt- Researches treatment of brain tumors with chemotherapy, hard because of the BBB (natural defense against chemical transport into the brain) introduction of chemicals to the brain by shrinking endothelial cells that make up the BBB with a concentrated sugar solution that creates gaps in the BBB allowing chemicals to enter (called Blood-Brain Barrier Disruption Therapy) project tenfold to a hundredfold more successful than normal chemotherapy and intra-arterial chemotherapy (Neuwalt, 1998)

Information Technology Acts
Technology has advanced greatly in the recent years. The internet has made it is easy for people to get any information they want, which in return presents danger to minors. This advance in technology has opened new issues that need to be addressed. Children depend on adults to protect them from any harm and as a result government passed acts to prevent child abuse on the internet. The two acts being discussed in this paper are the Childrenââ¬â¢s Internet Protection Act of 2000 and the Childrenââ¬â¢s Online Protection Act (COPPA) of 1998. Childrenââ¬â¢s Internet Protection Act, 2000 The Childrenââ¬â¢s Internet Protection Act (CIPA) is a federal law which was passed by Congress to prevent children from viewing the offensive or harmful content over the Internet (ââ¬Å"FCCâ⬠, 2013). CIPA regulates the schools and all public libraries. It makes it mandatory to filter all its computers to stop children from accessing sites that are not appropriate. (ââ¬Å"FCCâ⬠, 2013). The (CIPA) was passed in December 2000 and its main priority is to protect childrenââ¬â¢s innocent eyes from child pornography and other dangers of the internet. CIPA does not require a certain kind of filter system, but rather to make sure schools and libraries have some sort of filters to prevent such activities. There are online predators, inappropriate chat rooms, and sexual content that children are at risk for if this law was not passed. Ultimately, all households, schools, libraries, workplaces, and restaurant have access to the internet and this is a law that needed to be passed. Childrenââ¬â¢s Online Protection Act (COPPA), 1998 The Childrenââ¬â¢s Online Privacy Protection Act (COPPA) was passed in 1998. It specifically addresses children under the age of 13 that navigate thru any sort of internet service. COPPA requires anyone driving a website to have verifiable knowledge and consent from parents of any child 13 and under. Also, the driver has to get the consent of those parents before using any information given to them by the children. Furthermore, whether studying, shopping, surfing or chatting, children are blind to the fact that there are bad people who get their information and use it for all the wrong reasons. Advances in Information Technology The internet is a worldwide tool that is used for many different reasons. The Childrenââ¬â¢s Internet Protection Act of 2000 and the Childrenââ¬â¢s Online Privacy Protection Act of 1998 is a product of advances in information technologies. Regrettably, the internet can be used anywhere and anytime. The wireless fidelity, Bluetooth networks, and ultra wide-band network all give access to internet from any cell phone, computers, laptops, or tablets (Rainer Jr. & Cegielski, 2007). In addition, this creates a problem for minors because there are many online predators looking for ways to transition children into their world of viciousness. As a result, advance in information technology has created eye openers for every parent around the world. The advance in information technology opened issues that needed to be addressed because Children depend on adults to protect them. The government passed the Childrenââ¬â¢s Internet Protection Act of 2000 and the Childrenââ¬â¢s Online Protection Act (COPPA) of 1998 as a result of advancement in technology. As a matter of fact, parents should be more cautious as to what their children are using the internet for. Ultimately, the responsibility of a child falls on their parents References FCC.à (2013).à Retrieved from http://www.fcc.gov/guides/childrens-internet-protection-act Rainer Jr., K.
