Agriculture in India Essay Essay Example for Free

Agriculture in India Essay Essay India ranks second worldwide in farm output. Agriculture and allied sectors like forestry, logging and fishing accounted for 18.6% of the GDP in 2005, employed 60% of the total workforce[7] and despite a steady decline of its share in the GDP, is still the largest economic sector and plays a significant role in the overall socio-economic development of India. Yields per unit area of all crops have grown since 1950, due to the special emphasis placed on agriculture in the five-year plans and steady improvements in irrigation, technology, application of modern agricultural practices and provision of agricultural credit and subsidies since the green revolution. [citation needed] India is the largest producer in the world of milk, cashew nuts, coconuts, tea, ginger, turmeric and black pepper.[8] It also has the worlds largest cattle population (193 million).[9] It is the second largest producer of wheat, rice, sugar, groundnut and inland fish.[10] It is the third largest producer of tobacco.[10] India accounts for 10% of the world fruit production with first rank in the production of banana and sapota.[10] The required level of investment for the development of marketing, storage and cold storage infrastructure is estimated to be huge. The government has implemented various schemes to raise investment in marketing infrastructure. Among these schemes are Construction of Rural Go downs, Market Research and Information Network, and Development / Strengthening of Agricultural Marketing Infrastructure, Grading and Standardization.[11] Main problems in the agricultural sector, as listed by the World Bank, are:[12] * Indias large agricultural subsidies are hampering productivity-enhancing investment. * Overregulation of agriculture has increased costs, price risks and uncertainty. * Government interventions in labour, land, and credit markets. * Inadequate infrastructure and services. Research and development The Indian Agricultural Research Institute (IARI), established in 1905, was responsible for the research leading to the Indian Green Revolution of the 1970s. The Indian Council of Agricultural Research (ICAR) is the apex body in kundiure and related allied fields, including research and education.[13] The Union Minister of Agriculture is the President of the ICAR. The Indian Agricultural Statistics Research Institute develops new techniques for the design of agricultural experiments, analyses data in agriculture, and specializes in statistical techniques for animal and plant breeding. Prof. M.S. Swaminathan is known as Father of the Green Revolution and heads the MS Swaminathan Research Foundation.[14] He is known for his advocacy of environmentally sustainable agriculture and sustainable food security.

History Of The Bus Topology

History Of The Bus Topology A bus topology is a network set up in which nodes are connected to a segment of cable in the logical shape of a line, with a terminator at each end. A bus topology connects each computer or nodes to a single segment trunk. All nodes on the network share a common bus and use a multi-drop transmission medium. Bus network allows only one device to transmit at a time. A distributed access protocol determines which station is to transmit. The signal goes from one end of the bus to another. A terminator is needed at each to cut down the signal so it does not reflect back across the bus. CSMA/CA, media access method, is used to control the collisions that take place when two signals placed on the wire at the same time. There are two types of bus topology: Linear Bus Topology and Distributed Bus Topology. In Linear Bus Topology, all nodes of the network are connected to a common transmission medium which has exactly two endpoints. Distributed Bus in which all of the nodes of the network are connected to a common transmission medium which has more than two endpoints that are created by adding branches to the main section of the transmission medium. Bus networks do best with a limited number of devices. If more than limited computers are added to a bus, performance problems will be result. If the backbone cable fails, the entire network effectively becomes unusable. Fig: Bus Topology Ring Topology Ring network topology has no central server and connects computers in a circle of point-to-point connections. Each node handles its own applications. And also shares resources over the entire network. If one node becomes break down, the others are still able to maintain contact with one another. Such a network is best for decentralized systems because no priorities are required. The signal is transferred through a token for one station to the next. When a station needs to transmit, it grabs the token, attaches data and an address to it. And then routes it around the ring. The token travels along the ring till reaches the destination address. The receiving computer replies an acknowledgment to the sender source. The sender then releases the token for use by another computer. Each station on the ring has equal access but only one station can use token at a time. To allow an orderly access to the ring, a single electronic token passes from one computer to the next around the ring. A computer can only transmit data when it captures the token Fig: Ring Topology Star Topology A star topology is one of the most use common network topology where each of the devices and computers on a network connect to a central hub or sometimes just a switch. On a star network, data passes though the hub to its destination. The hub manages and controls all functions of the network. It also performs as a repeater for the data flow. In a star network, the entire network is dependent on the hub so if there is a problem with the hub, the entire network is not working. This makes it easy to troubleshoot by offering a single point for error connection and at the same time the dependency is also very high on that single point. Every computer in the network is safe when the hub is safe. This type of network also offers more privacy than any other network. The star network topology requires more cable than the usual Bus topology. A common cable that is used in star network is the UTP or the unshielded twisted pair cable. Another common cable that is used in star networks is the RJ45 or the Ethernet cables. If one computer fails in the network, it does not affect any other computer in the network and the purposes of this computer can be easily changed to the next computer easily using the controls of hub. In a Star Network Topology it is possible to have all the important data backups on the hub in a private folder so if one computer fails, it can still use data using the next computer in the network and accessing the backup files on the hub. New devices or nodes can easily be added to the Star Network by just extending a cable from the hub. Because of the hub controls everything, the addition or removal of devices are done using the hub. If the hub adds a device such as a printer or a fax machine, all the other computers on the network can access that new device by accessing the hub. The device is no need to be installed on all the computers in the entire network. The central function is cost effective and easier to maintain. Fig: Star Topology Mesh Topology A type of network configuration where each of the computers and network devices are interconnected with one another allows for most transmissions to be distributed even if one of the connections goes down. This type of topology is not commonly used for most computer networks because it is difficult and expensive to have redundant connection to every computer. In Mesh network, it can route data, voice and instructions between nodes. It allows for continuous connections and reconfiguration around broken or blocked paths by hopping from node to node until the destination is reached. A mesh network whose nodes are all connected to each other is a fully connected network. The network can still operate even when a node fails or a connection goes bad. On a mesh network, messages can send via any of several possible paths from source to destination. It employs one of two connection arrangements, full mesh topology or partial mesh topology. In the full mesh topology, each node is connected directly to each of the others. In the partial mesh topology, some nodes are connected to all the others, but some of the nodes are connected only to those other nodes with which they exchange the most data. Fig: Mesh Topology Different types of cables Different types of network cables are used depending on the kind of network. The type of cable used for a network depends on the networks topology, protocol, and size. If a network has large number of network devices, it will need cables that provide high speed and error free connectivity. Some of the cables being used today are Unshielded Twisted Pair (UTP) cables, coaxial cables and fiber optic cables. The UTP cable is the most popular variety, largely used for school networks as it transfers data at 100 mbps. Coaxial cables have a single copper conductor at their center. A plastic layer provides insulation between the center conductor and the braided metal shield. The outer metal shield blocks out outer interferences such as lights, motors and other computers. Fiber optic cables consist of a center glass core surrounded by several layers of protective materials. It transmits light rather than electronic signals and transfers signals over much longer distances than coaxial and twisted pair cables. Network cables are the backbone of any network. However, today several networks are switching over to other mediums of data transfer such as high frequency radio signals, and infrared light beams to connect the workstations. These systems are not only fast and effective, but also do away with the problem of maintain several hundred feet of cables spreading across the workspace. With such technologies coming to the forefront, the future may well tilt in favor of wireless systems. 10Mbps Networking Standard Cable Type Segment Length Connector 10Base2 Thin Coaxial 185 meters BNC 10BaseT Category 3, 4, 5 twisted pair 100 meters RJ-45 10BaseFL Fiber-optic 2000 meters SC/ST b) Advantages and Disadvantages of medium. Media Type Maximum Segment Length Speed Cost Advantages Disadvantages UTP 100 m 10 Mbps to 1000 Mbps Least expensive Easy to install; widely available and widely used Susceptible to interference; can cover only a limited distance STP 100 m 10 Mbps to 100 Mbps More expensive than UTP Reduced crosstalk; more resistant to EMI than Thinnet or UTP Difficult to work with; can cover only a limited distance Coaxial 500 m (Thicknet) 185 m (Thinnet) 10 Mbps to 100 Mbps Relatively inexpensive, but more costly than UTP Less susceptible to EMI interference than other types of copper media Difficult to work with (Thicknet); limited bandwidth; limited application (Thinnet); damage to cable can bring down entire network Fiber-Optic 10 km and farther (single-mode) 2 km and farther (multimode) 100 Mbps to 100 Gbps (single mode) 100 Mbps to 9.92 Gbps (multimode) Expensive Cannot be tapped, so security is better; can be used over great distances; is not susceptible to EMI; has a higher data rate than coaxial and twisted-pair cable Difficult to terminate c) Recommendation. Star topology would be the best way to use for renewing Townsville Police Department Network infrastructure because of in-house network (LAN) structure. Star topology should be also used for following reasons. Easy to install and reconfigure. No disruptions to the network when connecting or removing devices. Easy to detect faults and to remove parts. Less expensive. Includes robustness, that is, if one link fails, only that link is affected, other links remain active. It has been said that Townsville Police Department covers an area of 100 square kilometers and Townsville is divided into four districts (Northern, Eastern, Western and Southern). For that reason, the switch should be placed in the center of four districts. So, the network cable must cover 50 kilometer and the switch must be gigabit Ethernet. Therefore, UTP with cat6E is the most suitable network for such an area of network. Category 6 UTP Category 6 supports gigabit Ethernet and is recognized by standards bodies as supporting 10GBASE-T, however there are limitations that must be considered. The IEEE 802.3an standard cites a 55 meter distance limitation for standard category 6, which is not universally agreed upon within the TIA and ISO standards.TIA TSB 155 recently released a Technical Service Bulletin covering additional parameters for running 10GBASE-T on standard category 6. In this document a 37 meter distance limitation is referenced for 10GBASE-T on standards compliant category 6 systems. Between 37 meters and the IEEE referenced 55 meters, standard category 6 may support 10GBASE-T, but it is possible that the installer may have to use alien crosstalk mitigation techniques such as unbundling cables or replacing patch cords to improve the electrical parameters to allow 10GBASE-T to work properly. Above 55 meters, it is unlikely that category 6 UTP would work properly without a large amount of mitigation to reduc e alien crosstalk. A key takeaway is that using category 6 UTP for 10GBASE-T should be focused on existing installations, not new installations. The choice for new installations designed to support 10GBASE-T should be augmented category 6 UTP, STP or optical fiber systems. Category 6 Advantages  » Cost and size of media, relative to augmented category 6 and STP  » Installed base currently the dominant UTP cabling standard  » Installation widely accepted Category 6 Disadvantages  » Limited distance for 10GBASE-T  » External noise suppression at 100 m, relative to shielded systems or augmented category 6 Task 2 a) Nowadays, there are several usages of Internet by means of so many ways. There are three basic Internet services: Information (browsing, online-shopping, etc.) Communications (mail, chat, Video conferencing, etc.) Files sharing (downloading, uploading, etc.) b) The connecting suitable for above severs are as follows: For Information service: It can cover only 100 Kbits/s usually prove adequate. For Communication: For video conferencing, bandwidths of no more than 384 Kbits/s usually prove adequate. As for chatting communication, especially for yahoo chat, 28 Kbits/s should be enough. For File Sharing: As for file sharing, bandwidths of more than 1 Mbit/s are most suitable. c) The Internet Service Provider in Myanmar Myanmar Posts and Telecommunications The Myanmar Posts and Telecommunications (MPT), is the sole provider of telecommunication services in Myanmar. It is a Government Agency, operating under the Ministry of Communications, Posts and Telegraphs. It was founded in 1884 as a small Department of Posts and Telegraphs and has grown into the present day Myanma Posts and Telecommunications with approximately 13800 employees of which about 380 are managerial level staff. The present organization is headed by the Managing Director and a General Manager as his deputy. There are nine major departments operating under respective deputy general managers/chief engineers in the fields of administration, works and inspection, planning, training, finance, stores, automatic telephones, overseas communications and long distance communications. The three main categories of services rendered by MPT are the postal services, telegraph services and telephone services, for both domestic and international communications. d) Since, there is only one ISP in our country (Myanmar); we have to use MPT (Myanmar Posts and Telecommunication) as an ISP for our country. Task 3 a) Methods of Two-Way Voice communications Two-way voice communications (radios) are essentially available in three types: Hand-held portable, Vehicle-mounted mobile, and Desktop-base station There are also unique two-way radio devices such as indoor and outdoor call boxes and one-way radio receivers for wireless paging. Hand-held portable two-way radios are the walkie talkie type of radios. As ruled by the FCC (Federal Communications Commission), hand-held radios may not have more than 5 watts of power. Vehicle-mounted mobile two-way radios mount in a car or truck and they use the vehicles battery for power. They may have their own antenna, but better range is achieved by using an externally-mounted antenna. Desktop base station radios use wall AC power and they too may have a built-in antenna, but this antenna may be disconnected and then connected to cable that leads to an external-mounted antenna. The higher the antenna is mounted, the better the range. The vehicle-mounted mobile radios are usually used as base stations by just adding an AC to DC power converter. Mobile and Base station radios are usually more powerful than hand-held radios and may have as much as 100 watts of power. Frequencies There are two major frequency formats for two-way radios. They are Ultra High Frequency (UHF) radio and Very High Frequency (VHF) radio. Neither frequency band is inherently better than the other. They each have their pluses and minuses. Both formats are effective ways to communicate with another person. UHF radio The UHF radio band for commercial radios is between 400 512 MHz. Until recently, it wasnt widely used. Now, the UHF radio frequency is used for two-way radios, GPS, Blue-tooth, cordless phones, and WiFi. VHF radio The VHF radio band for commercial radios is between 130 174 MHz. FM radio, two-way radios, and television broadcasts operate in this range. Both UHF and VHF radios are prone to line of sight factors, but VHF a little more so. The waves make it through trees and rugged landscapes, but not as well as UHF frequencies do. However, if a VHF wave and a UHF wave were transmitted over an area without barriers, the VHF wave would travel almost twice as far. This makes VHF easier to broadcast over a long range. Two-way radios, hand-held portable, vehicle-mounted mobile and desktop base station are full duplex. b) Legal requirement for operation system Two -way radio devices Two-way radio power Antennas Channel usages FCC Licensing Audio Accessories Cases, Holsters, and Belt Clips Batteries Repeaters Drop-in Charger Multi-charging Units Selectable Power Operators Administrators Control station Additional and optional knowledge of two-way voice communication technology Overall knowledge of how to use a selected two-way voice communication device Costs of setting up and operating the system in my country As for hand-held two way voice communication device, according to amazon.com, the costs are as follows: For Cobra CTX400 GMRS/FRS 2-Way Rechargeable Radio with Hands-Free Operation (Pair) $36.88 For Townsville Police Department, total cost for using hand-held two way voice communication device is up to $2065.28. d) Limitations of each method (interference, range, etc.). Product Features 22 Mile Range, 22 Channels 121 Privacy Codes 10 Channel NOAA radio Hands-free operation (VOX) 8 Rechargeable AAA batteries, and a 2 port desk charger included Maximum range extender and belt clip included for maximum efficiency and carrying ease Lead-Free, Eco-Friendly Packaging e) As for following feature Highlights, tow way voice communication should be set up. VOX The Voice Activated Transmit (VOX) feature enables us to use our radio hands free. When VOX is turned on, the radio will automatically begin transmitting when we speak, without pressing the push-to-talk button. VOX works well for any application. On most VOX-capable radios there is a slight delay between when we start speaking and when the microphone turns on so the first part of the conversation may be clipped. Most radio users overcome this by repeating the first word. Military Specification Standards In an effort to achieve standardization objectives for purchases of products used by the military and other government organizations, the U.S. Department of Defense created standards that these products must meet. We will see these standards called military standard, MIL-STD, or MIL-SPEC. These standards ensure products meet certain requirements, commonality, reliability, compatibility, and similar defense-related objectives. According to Military Specification Standards, Townsville Police Department should be used Cobra CTX400 GMRS/FRS 2-Way Rechargeable Radio. Task 4 a) Since AVAYA IP Office 4.0 is only software for PBX telephone system, the main equipment that would be installed is only software. The procedure for the installation is as follows: Installation To establish and maintain an IP DECT installation, a network infrastructure is assumed, which comprises at least the following components: IP Base Stations IP DECT phone IP Office TFTP server (which can be the IP Office or 3rd Party) Depending on the operational requirements the following services should be provided: DHCP SNTP DNS WML/HTTP Syslog daemon b) AVAYA IP Office 4.0 Telephone System (IP DECT) Digital Enhanced Cordless Telecommunication The standard (ETS 300 175) essentially specifies the air interface, known as the radio interface. Voice and data can both be transmitted via this interface. DECT key technical characteristics are: Frequency range: approximately 1,880 1,900 GHz (approximately 20 MHz bandwidth) 10 carrier frequencies (1,728 MHz spacing) with 12 time slots each Doubling the number of time slots (to 24) using the TDMA process Net data rate per channel of 32 kbit/s (for voice transmission using ADPCM) Voice coding using the ADPCM method Maximum transmission power of 10 mW GAP Generic About the IP DECT Base Stations There are two types of IP Base Station. All IP Base Stations have the same hardware and software capabilities. Indoor IP Base Station The indoor IP Base Station is for indoor use only. It can be powered by a mains adapter or by 802.3af compliant power over Ethernet. Note For Australia and New Zealand the mains adaptor is not currently supported. Only 802.3af compliant power over Ethernet is supported. Outdoor IP Base Station The outdoor IP Base Station can be used outdoors or indoors. The outdoor IP Base Station can only be powered by 802.3af compliant power over Ethernet. Note Avaya Power over Ethernet adaptors are non 802.3af compliant, and therefore cannot power the ADMM. One of the IP Base Station within an IP DECT installation must be chosen (at installation time) to operate as the ADMM. This ADMM mode is in addition to the normal IP Base Station functionality that all the other base stations retain. c) Costs for installing AVAYA IP office There are two models of phones: the 3701 and 3711 phones. Avaya Kirk DECT phones (WT9620 and DT20) function on the IP DECT solution, but the functionality is limited. AVAYA Partner 18D- Digital phone 3 new from $95.00 Avaya 6408D+- Digital phone -multi-line operation Avaya 5621SWP IP Phone (700385982) Avaya IP400 Analog Trunk 4 card Available at external website: Atlas Phones for $199.00 d) Costs for operating the system Avaya IP Office Smart Card w/Voicemail Pro like new, available at external website: Atlas Phones for $1,095.00. Premise-based IP PBX systems vary extremely widely in cost and even more so as we look at wide-scale deployments and future growth and additions to a system. A basic premise-based box for a relatively small number of users say up to 20 in a single location can cost less than $1,000 excluding the phones themselves. But expansion costs and other branch locations can change the cost equation dramatically. In addition, we will have ongoing costs related to connection to the regular phone system and whatever connection costs are imposed by our backbone supplier. These ongoing costs are nevertheless going to be considerably lower than any other form of phone system. They should be lower than hosted VoIP solutions, and they will be dramatically lower than any older PBX and telecommunications provider. Phones are an additional cost, but when buying a premise-based IP PBX system, we often have greater flexibility than in any other arrangement. We can choose to go with very low-cost, no-name or bottom-of-the-line phones (which are still perfectly capable) all the way up to top-notch phones from manufacturers such as Polycom and Siemens that provide usability benefits (although often at a price premium). For Townsville Police Department, AVAYA Partner 18D- Digital phone should be used up to 6 base stations as for details, one Headquarter Reception Area, four Districts, and one serious crime squad. e) Recommendation for AVAYA The IP DECT solution delivers all the benefits of IP-based converged communications with the convenience of in-building wireless communications. Designed to support a large number of users, the IP DECT system enables users to carry a wireless phone and get full access to all the features they are accustomed to using at their desk phone. The IP DECT solution, which connects to the IP Office using a variant of the H.323 protocol, can support users in different offices that are connected via a WAN. An IP DECT cordless handset can travel from one office to another, making and taking calls. The DECT over IP system comprises the following components: At least one IP Base Station connected over an IP network and offering IP DECT as a wireless interface. A maximum of 32 IP Base Stations are supported. IP Office Small Office Edition, IP Office 406v2, 403, 406v1 or 412 with available VCM resources. IP DECT phone: Avaya 3701 and Avaya 3711 wireless phones. A maximum of 120 IP DECT phones are supported. Avaya IP DECT Mobility Manager (ADMM): management interface for IP DECT Wireless Solution, which runs on either one of the IP DECT Base Stations. The picture displayed next page gives a graphical overview of the architecture of the IP DECT Wireless solution. The IP Office, ADMM and the IP Base Stations communicate through the IP infrastructure. The IP Base Stations and the IP DECT phones communicate over air. Graphical overview of the architecture of the IP DECT Wireless solution Task 5 Task (5) This is the detail report for the overall tasks sorting from Task 1 to Task 4.In Task 1, the Townsville Police Department should be used Category 6 UTP by the following reasons:  » Cost and size of media, relative to augmented category 6 and STP  » Installed base currently the dominant UTP cabling standard  » Installation widely accepted And it is suitable for Townsville Police Department. Category 6 supports gigabit Ethernet and is recognized by standards bodies as supporting 10GBASE-T, however there are limitations that must be considered. The IEEE 802.3an standard cites a 55 meter distance limitation for standard category 6, which is not universally agreed upon within the TIA and ISO standards.TIA TSB 155 recently released a Technical Service Bulletin covering additional parameters for running 10GBASE-T on standard category 6. In this document a 37 meter distance limitation is referenced for 10GBASE-T on standards compliant category 6 systems. Between 37 meters and the IEEE referenced 55 meters, standard category 6 may support 10GBASE-T, but it is possible that the installer may have to use alien crosstalk mitigation techniques such as unbundling cables or replacing patch cords to improve the electrical parameters to allow 10GBASE-T to work properly. Above 55 meters, it is unlikely that category 6 UTP would work properly without a large amount of mitigation to reduc e alien crosstalk. A key takeaway is that using category 6 UTP for 10GBASE-T should be focused on existing installations, not new installations. The choice for new installations designed to support 10GBASE-T should be augmented category 6 UTP, STP or optical fiber systems. Townsville Police Department has been restructured within an area of 100 square kilometers. But Townsville PD could not over more than 500 square kilometers because the head departments are divided into four districts (Northern, Eastern, Western and southern). Cat 6 UTP could support that area. For Task 2, the services for internet connections are as follows: Information (browsing, online-shopping, etc.) Communications (mail, chat, Video conferencing, etc.) Files sharing (downloading, uploading, etc.) These services are the most common used for internet. And recommended connection speeds are as follows: For Information service: It can cover only 100 Kbits/s usually prove adequate. For Communication: For video conferencing, bandwidths of no more than 384 Kbits/s usually prove adequate. As for chatting communication, especially for most chatting communications, 28 Kbits/s should be enough. For File Sharing: As for file sharing, bandwidths of more than 1 Mbit/s are most suitable. There is only one Internet Service Provider in our country, Myanmar Ports and Communications. In Task 3, there are too many options for two -way voice communication devices. Two-way voice communications (radios) are essentially available in three types: Hand-held portable, Vehicle-mounted mobile, and Desktop-base station These are most common used for two-way voice communication. And I provided the recommendation the device as follows: Military Specification Standards In an effort to achieve standardization objectives for purchases of products used by the military and other government organizations, the U.S. Department of Defense created standards that these products must meet. We will see these standards called military standard, MIL-STD, or MIL-SPEC. These standards ensure products meet certain requirements, commonality, reliability, compatibility, and similar defense-related objectives. According to Military Specification Standards, Townsville Police Department should be used two way voice communication technology. For Task 4, the main equipments that would be installed are just only the software. There are so many options and vendors that provide telephone known as PBX. Among those vendors, I chose AVAYA IP Office 4.0 Telephone System (IP DECT). As for Townsville Police Department, like military office, it is important to choose the right products. The IP DECT solution delivers all the benefits of IP-based converged communications with the convenience of in-building wireless communications. Designed to support a large number of users, the IP DECT system enables users to carry a wireless phone and get full access to all the features they are accustomed to using at their desk phone. The IP DECT solution, which connects to the IP Office using a variant of the H.323 protocol, can support users in different offices that are connected via a WAN. An IP DECT cordless handset can travel from one office to another, making and taking calls.

Belief systems :: essays research papers

Belief Systems The religious beliefs of people along the Silk Road at the beginning of the 1st century BCE were very different from what they would later become. When China defeated the nomadic Xiongnu confederation and pushed Chinese military control northwest as far as the Tarim Basin (in the 2nd century BCE), Buddhism was known in Central Asia but was not yet widespread in China nor had it reached elsewhere in East Asia. Christianity was still more than a century in the future. Daoism, in the strict sense of that term, connoting an organized religion with an ordained clergy and an established body of doctrine, would not appear in China for another three centuries. Islam would be more than seven centuries in the future. The peoples of the Silk Road in its early decades followed many different religions. In the Middle East, many people worshiped the gods and goddesses of the Greco-Roman pagan pantheon. Others were followers of the old religion of Egypt, especially the cult of Isis and Osiris. Jewish merchants and other settlers had spread beyond the borders of the ancient kingdoms of Israel and Judea and had established their own places of worship in towns and cities throughout the region. Elsewhere in the Middle East, and especially in Persia and Central Asia, many people were adherents of Zoroastrianism, a religion founded by the Persian sage Zoroaster in the 6th century BCE. It posited a struggle between good and evil, light and darkness; its use of fire as the symbol of the purifying power of good was probably borrowed from the Brahmanic religion of ancient India. The Greek colonies of Central Asia that had been left behind after the collapse of the empire of Alexander the Great had, by the 1st c entury BCE, largely converted from Greco-Roman paganism to Buddhism, a religion that would soon use the Silk Road to spread far and wide. In India, on side routes of the Silk Road that crossed the passes to the Indus Valley and beyond, the older religion of Brahmanism had given way to Hinduism and Buddhism; the former never spread far beyond India and Southeast Asia, while the latter eventually became worldwide in extent. Coming at last to China on our west-to-east survey of the ancient faith of the Silk Road, we .nd that rulers worshiped their own ancestors in great ancestral temples; they were joined by commoners in also worshiping deities of the earth, the four directions, mountains and rivers, and many others.

Red Sorghum :: essays research papers

Red Sorghum Claire Huot China’s New Cultural Scene   Ã‚  Ã‚  Ã‚  Ã‚  The film Red Sorghum was one of the most popular Fifth Generation films in China and Abroad. As an adolescent American kid, probably the average, I got to see a new perspective of China through this class. I wanted to compare the West’s interpretation with Chinas’. One of the first things I did was compare Chinese cinema to well known American cinema. Zhang Yimou’s first film as director, Red Sorghum was immensely popular at home and abroad. The film follows a popular novel with its point of view; an off-stage, present-day male narrator whose own life is ancient and minute compared to the family he was grateful to have been associated with. Compared to a classic American Movie this is very much the same. The movie I am talking about is Legends of the fall. In almost the exact same way this movie was made. An older Indian gentleman begins to tell the story he lived. He grew up in a great family, with great traditions. Then he narrates the tale of a family and its struggles through love, war, bitterness, and bad times. Its starts with that voice, on a blank screen: â€Å"I will tell you the story of my grandpa and grandma†¦Ã¢â‚¬  In LOTF an older Indian man starts telling the story of â€Å"Tristan’s stormy birth† We then see the hero at a very young age, fighting a bear. In Red Sorghum instead of the exp ected old granny, we see a beautiful, twenty-something woman who, looks very attractive.   Ã‚  Ã‚  Ã‚  Ã‚  When Nine arrives at the distillery and rallies all the men together to work, its comparable to the first time Susanna arrives at the ranch. Run by mostly men, she has some women, but the men all look at her with admiration. Right away Tristan is taken to her. When she is out riding and lassoing the cow, is like Nine rounding up the Sorghum to work. Tristan automatically chases a nearby Mustang and catches it. Much like Grandpa catching the first â€Å"thief† on the travel through the sorghum fields. He comes back with a mustang, and Grandpa now has Nine’s appreciation.   Ã‚  Ã‚  Ã‚  Ã‚  There are many script similarities, and cut similarities between these two films, yet LOTF has a more comprehensive plot, to me. Maybe its loses something in the sub-titles, that I don’t find it as intriguing as American Cinema.   Ã‚  Ã‚  Ã‚  Ã‚  One script point in particular in LOTF is the fact that the father was a former military chief, and he left that â€Å"madness† for a more peaceful life.

Color Essays -- essays research papers

Color is sensed when white light bounces off an object and is reflected into the eye. Objects appear different colors depending on what colors were absorbed and which were reflected. Color is "seen" by the rods and cones in the eye. Cones detect color and rods detect black, white, and shades of gray. People who cannot see colors properly are colorblind. There are many different kinds of colors and they are classified in many different ways (The World Book Encyclopedia p 818, 819). The eye consists of many parts. The part of the eye you can see when you look at someone consists of four parts. The colored part of the eye where the light enters is called the iris. The white part around the iris is the conjunctiva and episclera. This part also contains blood vessels. The cornea is the clear covering of the iris and pupil. The cornea contains no blood vessels. The lens is located behind the iris. The lens is used to focus, as in the cornea, but the lens can move. The retina is responsible for telling the brain what a person is seeing. They determine all the different parts of what is being seen. It then codes them to electrical signals for the brain (Cassel p 4-10). Rods and cones are in the retina. There are three kinds of cones. Each cone can sense a different color. Rods are used when a person is in dim light (Hubel p 162). The optic nerve is what sends all these messages to the brain (Cassel p 261). Sometimes people have difficulty telling colors apart. This is called colorblindness (Webster's Dictionary, p 281). Sometimes colorblindness is hereditary. Other times there is a problem with the message reception from the optic nerve. Another problem can lie in the retina. People can have trouble recognizing colors because of certain drugs. People are diagnosed as being colorblind by taking tests. They look at different colored numbers that are in order by their color. This way they can be diagnosed as being colorblind in certain areas (Cassel p 52). A person can have different extents of colorblindness depending on what the problem is. A person can be colorblind because t... ...ht or white the colors will appear reversed. Red becomes green, and yellow becomes blue (The World Book Encyclopedia p 820, 819). A quote about afterimages was given by Johannes Ilten: "It has been psychologically proven that the afterimage as well as the simultaneous effect show the strange and so far inexplicable fact that our eye demands for a given color it's complementary completing and produces it on it's own if it is not provided" (Tritten p C43). Color is a product of many different things. We physically see color by the light hitting the retina and being absorbed by the rods and cones. Colors are distinguished by sorting them into categories. These could include tint, shade, tone, chroma, value, or hue. It could also be determined by whether a color is primary, secondary, intermediate, or complementary. The illusion of different colors can be created by the colors around a color or placing bits of color very close together as in a television. Afterimages create the opposite of colors. All color is a product of light. Without light, we would only be able to see in black and white (The World Book Encyclopedia p 818, 819, 822, 823).

Medieval Ages v. Renaissance Culture

Love remained a major theme in the Medieval and Renaissance Literature but this form of romantic passion is depicted differently is both eras. In the Medieval era, its takes the form of ‘courtly love’ and was labeled as a noble passion coupled with chivalry and gallantry. In renaissance, love was also considered an ennobling phenomenon but we see concept of romantic and exalted love that has nothing to do with knightly and chivalrous qualities. In the short story of Equitan, courtly love is not depicted an immodest and lustful phenomenon but it is praised occasionally. It further shows certain other fine qualities of the contemporary culture. Equitan was not a usurper. Although being a king, he was able to keep his seneschal’s wife by force or decree but he took into account both the seneschal and his wife’s feelings over the issue. Following the tradition of courtly love, he disclosed his love for the lady and requested her hand. This clearly manifests that culture and value of time pertaining to courtly love strongly prohibited forced love. Furthermore, it shows the individual integrity and honesty within the community. It was king’s integrity and honesty that did not let him deceive his seneschal and adopt a proper way to court the lady. When Equitans disclosed his feeling for her, she requested time to ponder over the matter. This indirectly depicts the rationality level of the people in general and nobility in particular. King was not swayed by the strong emotions and lady (seneschal’s wife) was not also seduced emotionally. Loyalty and equality were other ingredients of the courtly love that portrays the values and traditions of the society as a whole. Seneschal wife says in this regard; Love is not honourable, unless it is based on equality. A poor man, if he is loyal and possess wisdom and merit, is of greater worth and his love more joyful than that of a prince or king who lacks loyalty. This further depicts that females were not considered an object of pleasure only. They have their own say in the amorous and domestic affairs. It was a two-way affair. All the short stories and primary sources clearly indicate that indulgence in courtly love was not considered a social evil but was sanctioned by the society. People used to admire knights and mistresses involved courtly affairs. Although wealth and power was taken into account while making a courtly love to a man or woman but chiefly it was beauty and merits on the part of the woman and man that were considered as the pre-requisites for courtly love. For example the Lady Love in Letters of Abelard and Heloise describes ‘two special gifts whereby to win at once the hearts of any woman’   of her male lover. Those are his ‘gifts for composing verse and song’ and his ‘manhood’. This shows that contemporary community was not too materialistic in the affairs of love. Letters of Abelard and Heloise clearly manifest that marriage was not the objective or outcome of courtly love. The objective was to involve in the fine and subtle passion and feel the delicacies of the excitement. Mistress was considered more adorable title than that of wife. The â€Å"Renaissance† was usually the Age of Idealism the concept of love was also transformed and it was associated with spirituality. However we find juxtaposing view about the concept of love in the long period of Renaissance. For example in ‘The Merchants Tale’, Chaucer does juxtapose genre of courtly love and religion against each other and mocks both of them. Different precepts of courtly love are satirized by characterization and are undermined to an extent by effective utilization of images, descriptions and tone that it seems comical and illogical. So a phenomenon, courtly love that was eulogized in the medieval period is mocked. This poem, as it were, holds a mirror to the life of Chaucer’s age and shows it manners and morals completely, so it is obvious that lovers were always disliked and condemned by their families and societies in the renaissance period. Petrarch (1304-1374) is considered â€Å"the first writer of the Renaissance† takes into account the idealized form of love. Unlike medieval concept of courtly love, romantic love of renaissance literature was devoid of sexuality and eroticism. Petrarch shows the pangs of love and labels it as deadly disease or wound. He says in this regard; Weeping I laugh, I feed on misery, by death and life so equally dismayed: for you, my lady, am I in this state.(Sonnet, 134, Translation) Beloved is an exalted female figure that has nothing to do with materialistic world. But she was a more realistically conceived and presented figure than in the literature of courtly love. So above-mentioned arguments and evidence clearly show that concept of love was different in both periods. One was based on the desires of the flesh and feelings whereas other was based on its spiritual and transcendental nature. References Brewer, Derek. Chaucer and his world. New York: Dodd, Mead, 1978.
