Interventions and preventative management related to skeletal traction

Interventions and preventative management related to skeletal traction List nursing interventions and preventative management related to skeletal traction. As what we had discussed, traction is the application of pulling force to a part of the body. There are two types of traction, the skin traction and the skeletal traction. In skeletal traction, the traction is directly applied to the bone by the use of metal pin or wire. To maintain an effective traction, the nurse must check the traction apparatus. Make sure that the ropes are positioned properly in the pulley track, ropes are not ragged, the weights hang freely and the knots in the rope are tied securely and make sure that the skeletal traction equipment are tight. Check the pins to be sure they are secure and tight, and insert the small finger or the index finger between the vest and the patients skin to be sure the vest if comfortable and not too tight. The nurse must also maintain the position of the patient. Inspect the patients proper body alignment every 2 hours. Avoid foot drop, inward rotation and outward rotation. The foot of the patient may be supported in a neutral position. Monitor neurovascular status of the patient at least every 4 hours. The patient must report to the nurse if there are any changes in his sensation or movement. The immobilized patient is risk for DVT. So, encourage the patient to do active flexion and extension of the extremities and isometric contraction of the calf. Also, anti-embolism stockings, anti-coagulant therapy may also be used to prevent thrombus formation. Instruct the patient to exercise to maintain strength and tone of his muscle. Also, this will help in patients rehabilitation. Pin at the insertion site may be risk for infection or the development of osteomyelitis. Pin care should be performed 1 or 2 times a day. Clean the site with chlorhexidine solution or water and saline. The nurse must inspect the pin every 8 hours for infection. When pins are stable for 48- 72 hours, weekly pin site care is suggested. The nurse must prevent skin breakdown by inspecting the elbows and heels for pressure ulcers. A trapeze can be used to help the patient move about in the bed without the use of elbows and heels. The nurse must keep the bed dry and free from crumbs and wrinkle for patient who is unable to change positions. Discuss a component of cast care for the pediatric client or adult client. Identify manifestations of compartment syndrome. General cast care includes avoid getting cast wet, especially padding under cast-cause skin breakdown as plaster casts become soft. Moisture weakens plaster and damp padding next to the skin can cause irritation. Advise the patients that do not cover a leg cast with plastic or rubber boots, as this causes condensation and wetting of the cast. Also, avoid weight bearing or stress on plastic cast for 24 hours. Report to the physician if the cast cracks or breaks, instructs the patient not to fix it himself. To clean the cast, remove surface soil with slightly damp cloth, rub soiled areas with household scouring powder, and wife off residual moisture. For pediatric patient there are some additional cast cares. The child is usually more troubled by immobilization than the adult. A special attempt should be made to ensure that his activities are as normal as possible and that full use is made of his unaffected joints and muscles. The younger child may not be able to understand why the cast is necessary. He may attempt to remove it. Allow the child to work through his question and feelings via play like giving her a doll with a cast. Children may be frightened by the removal of the cast. They often think of cast as part of their body and may be helped by analogies of having fingers nails or hair cut. Age- appropriate explanations and demonstrations should be provided. Parents should be instructed in care following cast removal. Daily soaking of the area may be necessary to remove desquamated skin and secretions. Oil or lotion may provide comfort to the child. Exercise should be done as prescribed to increase strength and function. Manifestations of compartment syndrome: In acute compartment syndrome: The classic sign is pain in the injury site. Stretching the muscles increases the pain. There will be tingling or burning sensation in the skin. The muscle will feel tight. The late sign of compartment syndrome is paralysis indicating permanent tissue damage. In chronic compartment syndrome: There is pain and cramping during exercise. The pain usually subsides when the activity stops. Numbness Difficulty moving the foot Visible muscle bulging Compare the nursing needs of a total hip replacement patient with those of a total knee replacement patient. In patient who had undergone hip replacement, nursing intervention focuses on preventing dislocation of hip prosthesis. The nurse must instruct the patient to position his leg in abduction because this may prevent dislocation of the prosthesis. A wedge pillow is usually placed between the legs to remain the legs abducted. Also, the hip of the patient should never be flexed for more than 90 degrees. When the patient sits, advice him than his hips should be higher that his knees. The patients affected leg should not be elevated and the knee may be flexed. Emphasize to the patient that he should maintain his legs in abducted position, to avoid internal and external rotation, hyperextension and acute flexion. Due to invasive procedure, there will be fluid and blood being accumulated. The nurse must remember that drainage is still normal if 200-500 ml of fluid were drained for the first 24 hours and after 48 hours it usually decreases to 30 ml or less. Report to the physician if the volum e of the drainage is greater than expected. Risk for deep vein thrombosis is common after the hip replacement because of immobility. Anti-embolic stockings, anti-thrombolytic medication can be used as preventive measures. Advise the patient to report any signs of calf pain, swelling and tenderness because it may indicate DVT. One of the serious complications after hip replacement is infection; it may occur within 3 months after surgery and associated with hematomas. Use of aseptic technique for dressing changes should be observed and implemented to avoid introducing organisms. Severe infections may require surgical debridement or removal of the prosthesis. In patient who had undergone knee replacement, nursing intervention should focus on mobilizing the patient. While in hip replacement the patients legs should be abducted, in knee replacement the patient is encourage to do active flexion of the foot every hour when the patient is awake. Like in hip replacement, knee replacement is also risk for deep vein thrombosis. Active range of motion, anti- embolic stocking and anti-coagulant can be used to prevent DVT. Also, knee replacement is an invasive procedure and its fluid had accumulated in the joint. Drainage of this replacement may ranges from 200-400 ml during the first 24 hours and less than 35 ml by 48 hours. If extensive bleeding happens, an autotransfusion drainage system may be used during postoperatively. Change in the characteristics and amount of drainage is promptly reported to the physician. Encourage the patient to use a continuous passive motion device with physical therapy to improve patients knee mobility, decreased hosp ital stay and minimize the intake of analgesic agents. The nurse must assist the patient to get out of the bed on the second postoperative day and start ambulating as tolerated. Discuss methods to avoid dislocation after hip replacement surgery. Dislocation of the hip is a serious complication of surgery that causes pain and necessitates reoperation to correct the dislocation. The desirable positions such as abduction neutral rotation and flexion of less than 90 degrees must be emphasized during the patient teaching. Instruct the patient to keep the knees apart at all times by putting a pillow between the legs to keeps hip in abduction and in neutral position to prevent dislocation. The patient should never cross his/ her legs while sitting. Avoid bending forward while sitting in a chair. The patient should not flex the hip to put on clothing such as pants, stockings or socks. Use a high-seated chair and a raised toilet seat. You are caring for a patient who has had skeletal traction placed to treat a fractures femur. Discuss nursing interventions and assessment techniques related to this type of treatment. Fracture of the femur usually is treated with some form of traction to prevent deformities and soft- tissue damage. Skeletal traction is used to align the fracture in the preparation for the future reduction. Traction restricts patients mobility and independence; therefore the nurse must assess and monitor the patients anxiety level and psychological responses to traction. Since the patient requires assistance with self-care activities, the nurse must help the patient to eat, bathe, dress and toilet. Assess the patient and the traction set-up to determine the best method for changing the bed linen. Eliminate any factors that reduce the traction pull or alter its direction. Ropes and pulleys should be in straight alignment and the ropes should be unobstructed. The nurse must inspect the body part that is placed in traction and its neurovascular status to determine if there is sign of inflammation. Because the patient is confined to bed, the nurse must implement measures to prevent complications of immobility and inactivity. One of the complications in patient to skeletal traction is atelectasis and pneumonia due to immobility. To assess respiratory status, the nurse auscultates the patients lungs every 4-8 hours. Teach the patient deep exercises to fully expand the lungs and to clear out secretions. Constipation is also a complication due to decreased peristalsis, a high fiber diet and fluids may help stimulate gastric motility. Urinary infection is also a common complication because of incomplete emptying the bladder due to the uncomfortable effects of voiding into a bed pan. The nurse must encourage the patient to drink large quantities of water and to void every 3-4 hours. DVT is also a serious complications, nurse must assist the patient in foot and ankle exercise. Also, drinking a lot of fluids makes the patients hydrated and prevents homoconcentration which can contribute to stasis. A patient is being discharged with an external fixator for a fractured humerus. Discuss home care instructions for this patient. These are the instructions that the nurse must teach to the patient before discharge: Patient must inspect each pin site for signs of infection and loosening of pins. Watch for pain, soft tissue swelling and drainage and consult a physician when it occurs. Cleanse around each pin daily, using aseptic technique to prevent contamination of bacteria leading to infection. Do not touch wound with your bare hands. Clean fixator daily to keep it free of dust and contamination. Do not tamper with clamps or nuts because it can alter compression and misalign fracture. Encourage the patient to follow rehabilitation regimen because it is helpful in teaching the patient to use ambulatory aid safely, adjust to weight- bearing limits and altered gait patterns. Identify various types of traction and the principles of effective traction. The first type of traction is the running traction, it is a form of traction in which the pull is exerted in one plane; it may be either skin or skeletal traction and Bucks extension traction is an example of running skin traction. The other type of traction is balanced suspension traction, which uses additional weights to counterbalance the traction force and floats the extremity in the traction apparatus. The line of pull on the extremity remains fairly constant despite changes in the patients position. According to our discussion, to achieve an effective traction, countertraction, a force acting to the opposite direction, is applied. The patient body weight and positioning in bed supply the counterforce; Traction must be continuous to reduce and immobilize fracture; Skeletal traction is never interrupted; weight are not removed unless intermittent traction is prescribed; any factor that reduces pull must be eliminated; ropes must be unobstructed and weight must hang freely and knots or the foot plate must not touch the foot of the bed. Discuss the use of Bucks traction, its uses and the involved nursing considerations. Bucks traction is skin traction to the lower leg. It is used to immobilize fractures of the proximal femur before surgical fixation. It can be use for hip and knee contracture, preoperative and postoperative positioning and immobilization of hip fractures, muscle spasm, joint rest. Nursing management: Ensure skin integrity by avoiding pressure on heel, dorsum of foot, fibular head, or malleolus. Maintain countertraction by elevating foot of the bed or keeping head of bed flat. Encourage independence with use of trapeze. Do not put a pillow under the affected limb. Observe skin by removing traction, with someone holding the leg in alignment with manual traction, at least once every shift. A maximum of 10 lb of traction should be used. Discuss the nursing care for a patient undergoing orthopedic surgery. Preoperative nursing care: In relieving the pain of the patient, elevation of the edematous extremities promotes venous return and reduces discomfort. Also, the use of ice relieves swelling and reduces discomfort by diminishing nerve stimulation. The physician may order analgesic to control the acute pain of the musculoskeletal injury. The nurse must also maintain adequate neurovascular function by assessing color, temperature, capillary refill, sensation and motion of the extremities. For the nurse to promote health to the patient, th nurse should assist the patient in performing activities that promote health during the perioperative period. The nurse also assesses nutritional status and hydration. The goal of the nurse in the preoperative period is to focus on helping the client to experienced reduced pain; continue to be active, mobile and injury free; and practice measures to reduce the potential for postoperative wound infection. Postoperative nursing care: The nurse assesses the patients level of pain since pain is common after orthopedic surgery. the use of repositioning, relaxation, distraction and guided imagery may help in reducing the patients pain. The physician must order patient- controlled analgesia and epidural analgesia to relieve the pain. In maintaining an adequate neurovascular function, the nurse must instruct the patient to perform muscle- setting, ankle, and calf-pumping exercise hourly while awake to enhance circulation. Encourage the patient to increase intake of foods that is rich in protein and vitamins because it is essential for wound healing. Positioning the patient at least every 2 hours can minimize pressure ulcer and skin break down. The patient may use assistive device for postoperative mobility. There are potential complications that may arise after the surgery. The goal of the nurse is to the patient is to exhibit absence of complication. The patient is risk having pneumonia and atelectasis, the nurse must instruct the patient to deeply breath and cough every 2 hours to expand the lungs and mobilize secretions; encourage the use of incentive spirometry to increase respiratory effort; turning the patient at least every 2 hours to prevent pooling of secretions and auscultate lung sounds every 4 hours to note for breath sounds. The patient is also risk for infection. When changing the dressing of the patient and performing pin care, the nurse must use aseptic principle to reduce microorganisms that may go into the wound and incision; keep the wound drainage system below the level of incision to prevent backflow of the drainage; and administer prescribe antibiotics to control the infection. The patient is also risk for deep vein thrombosis. The nurse encourage the patient to us e ankle and calf- pumping exercises, anti embolism stockings. To avoid constipation, the nurse encourages the patient to increase fluid intake to 2000 ml/ day unless contraindicated to prevent fecal impaction. Sources: Brunner, Suddarths et al. (2008).

Explain your findings in a one-page paper. The nurse must instruct their patient to rest and keep the affected extremity elevated on a one or two pillow as much as possible during the first 24 hours. The use of crutches may be suggested for your patients with a leg cast or a sling for patients with an arm cast for use during the first 24-48 hours. Remind your patient that the cast must be dry at all times. Advise them that water or any liquids will cause the plaster to weaken and it may lead to skin irritation. While bathing, instruct your patient to cover the cast with a plastic bag, tape the opening shut, and hang the cast outside the tub. Even when covered with plastic, you should not place the cast in water or allow water to run over the area. If the cast becomes wet, your patient can dry it with a hair dryer on the cool setting. Do not use the warm or hot setting because this can burn the skin. Your patient can also use a vacuum cleaner with a hose attachment to pull air through the cast and speed drying. To decrease swelling and pain in the first 24-48 hours, your patient should place crushed ice in a plastic bag, covered with a pillow case or towel, on the cast over the injury every 15 minutes per hour while awake. Do not apply ice directly to the skin. Dents or compression of the cast can cause pressure or irritation to the skin beneath the dressing, which may develop sores or ulcers. The nurse must teach the patient to reposition his body every two hours during the first 24 hours to allow even drying of the cast and every two hours when awake thereafter to avoid developing pressure sores on the skin. Do not place anything inside the cast, even for itchy areas. Sticking items inside the cast can injure the skin and lead to infection. Using a hair dryer on the cool setting may help soothe itching. The cast should be inspected regularly. If it develops cracks or soft spots, the physician should be notified. The patient should never attempt to remove the cast. The physician will remove the cast at the appropriate time with a special saw that cuts through the casting material but will not damage skin. Advise the patient that a serious complication can occur after cast application which is known as compartment syndrome. Instruct your patients to call the physician at once if any of the following signs or symptoms appear such as increased pain combined with the feeling that the cast is too tight, numbness and tingling in the hand or foot, burning and stinging sensations, excessive swelling in the part of the limb below the cast and inability to actively move the toes or fingers Advise your patient to seek for medical help if there are sores areas or a foul odor from the cast, cracks or breaks in the cast, or the cast feels too tight, if there is swelling that causes pain, if the patients fingers or toes are blue or cold or the cast becomes soaking wet and does not dry with a hair dryer or vacuum.

How The Internet Changed Our Lives

How The Internet Changed Our Lives Electronic communication system is an array of systems that can help us transmit the information over long distances, in electronic format, i.e., in the form of flow of electronic current. Electronic communication can include the types of various forms of the communication types. They can be radio communication, internet communication, mobile phone communication, landline phone communication etc. The electronic communication is now an integral part of the human life and the scope of this communication is beyond limits. Electronic communication has brought the world too near and no corner is beyond the reach of one or the other communication forms. From Letters to e-mails and web communications, the progress is noteworthy. Television and radio communication have enabled the spread of mass media to a very large extent. The revolution of the electronic communication started with the invention of the telegraph. The only limiting factor in the case was the need of copper wires for transmission, which proved costly. But the advent of radio communication proved a boon in the case for far away and distant communications. After the expansion of the radio spectrums, the possibilities in the fields of the wireless communications have given various potentials for communication systems. The essence of making each and everything accessible, communicable, and reachable within a few clicks has been made possible by something known as INTERNET. This is the keyword of the topic of the term paper, and as such, much of the emphasis would be given on this topic, over the other forms of electronic communication systems. Internet has led to an economic prosperity, and the development of intelligent search engines has enabled man to search for any information within a few clicks and in a matter of micro seconds. The World Wide Web, which is known as www, is growing exuberantly. It already has billions of pages, and is growing at the rate of millions of pages per day. Hardly is there any sort of topic which has no finding on the internet. Computers are already an integral part of our life, and as such, the internet has enabled the users to connect on a worldwide level. Communication System A communication system has various channels which are staged in such a way that communication is carried out with the most possible efficiency. A typical communication system has the following channels: Transmitter Medium Receiver Transmitter: this unit mainly functions for the conversion of a signal into the form which can be transmitted over further distances. This may include Transducers, amplifiers, modulators etc. Medium: this is the channel in which the signal propagates. This is mostly air in wireless communications. While radio waves can propagate in any medium, including vacuum. This is sometimes referred to as PROPAGATION channel, or PHYSICAL channel. The most recent development is in the form of OFCs, the optic fibre cable, which as a high efficiency, and enormous speed. Receiver: this unit receives the signal, converts it to the desired form for reception, and presents it to the receiving end. This unit includes antenna assembly, amplifiers, demodulators, receiver units etc. There are some important aspects in the electronic communication systems which can be highlighted: Modulation: the process of imposition of weak signal over a strong carrier signal is known as modulation. Modulation generally requires the use of high frequency signals, as the low frequency signals cannot be transmitted over long distances. Modulation also helps in conversion of the digital signals to analog forms for transmission over a distance. AM, FM and PM are the forms of modulation. FM is the most used forms of modulations in the general forms of communications. Analog and Digital signals: these are the properties of signals which distinguish them b/w continuous of discrete signals. Analog signals are continuous signals, which are defined at each and every instant of time, while the digital signals are discrete signals. They are defined only after a particular interval of time. Here, the blue continuous lines represent the analog signal, while the red dotted patterns show the digital or discrete values of the signals. Types of modulation: Amplitude Modulation- AM works by varying the strength of the transmitted signal in relation to the information being sent. Frequency Modulation-It is the process of conveying the information over a carrier wave by varying its instantaneous frequency . Phase modulation-Phase modulation (PM) is a form of modulation that represents information as variations in the instantaneous phase of a carrier wave. Internet in our daily Life Now, I would start to emphasise on the main topic of the term paper, Use of internet in our daily life. Around 10 years ago, hardly the 20% of the population of India would have heard about this word. Yet a lesser quantity would have used the internet even once. But now, imagining the life without internet is something which is really beyond our scope. It is the internet which has revolutionized the each and every sphere of our day to day life. How internet works? This is the diagram which tells us how the internet communication takes place. The key factor here is the ISP which helps to link between the user and the Main internet. Major ISPs in India: An ISP or the Internet Service Provider is some agency which links a user, who can be an individual or a group. An ISP may provide internet access through a dedicated line, a telephone line or the Wireless modems. A list of major ISPs in India is as below: BSNL MTNL Bharti Airtel Connect Idea InfoTech SIFY Reliance Tata Indicom BSNL and MTNL are the government sector companies; they together occupy 56% of the total market share. Airtel is the leader amongst others. Channels of internet access: Narrow-band telephone line- This is a particularly dial up type connection which provides a low bandwidth connection. The speed of the internet communication is a maximum of 56 kbps in this type of connection. This type of system uses a PSTN or PUBLIC SWITCHED TELEPHONE NETWORK. The user has to dial a number from the computer to get connected. A dial up modem in the computer encodes and decodes the packet signals, which are known as Internet Packet signals. This is a type of dial up modem which is used in the computers for dial up connections. This type of modem is generally internally fitted in the computers. All telephone lines work at a maximum signal speed of 64 kbps. 8 kbps has to be excluded out for the transfer guard band. As a result, the maximum possible speed in a dial up network can be 56kbps. But the major factor in this regard is that if there are a number of users, there would be traffic in the telephone exchange. As a result the speed would gradually decrease. It was often noticed in earlier days that during peak hours, the speed used to be around 10-15kbps while in non-peak hours; the speed could reach to around 40kbps. But it hardly reached to the top notch of 50+. The major drawback in this system that lead to its failure was not only the speed. This type of connection was billed in the terms of duration of connection. That means, whether it is transmitting or not, it will cost the user, regardless of the speed and amount of data transfer. The user was charged for net connection, as well as the telephone cost as a result, it would cause a high rise in the telephone bills of the users. Costs to the users: Till date, only BSNL and Connect have provided the dial up connection to the users. BSNL charges Rs. 6 per hour for the connection, and rupees 2 per 15 minutes of call connection. This implies that for one hour, a person is charged rupees 14. If the average speed is 40 kbps, the person can download 18 MB of data in an hour. But speed hardly reaches till 40 kbps. As a result, the fluctuation in the bandwidth would result it to be too expensive to the user. Present Scenario: At present, only BSNL is providing a dial up service. But this service has a limited number of users, mostly in the areas where the broadband has not reached, or the users who do not want to buy broadband due to very less usage. A majority of the user group has upgraded to the broadband internet. Future: The only dial up connection provider BSNL has decided to continue the dial up networking till the broadband reaches to the most remote areas. There is no scope of improvement in this channel of internet communication as it has already reached its limits. There is no chance of defying these limits. Advantages: This channel has practically no advantages over other channels of internet transmission, if we compare it to other types. This was the first form of internet communication to the public. This paved the ways for other types of internet. Wired Broadband Internet: This is the most used form of internet in the world. This type of internet is the most versatile and the most wide channel one, which can be transmitted over a wide variety of lines. They include the telephone lines, the television cable, dedicated lines etc. A broadband connection is the one which has a minimum bandwidth of 256 kbps. It is the high speed channel of internet communication. The major advantage of this network is that the number of users in this type of networks generally does not affect the speed. Also, the phone lines through which the line has been connected can be used both for phone as well as the internet connection simultaneously. It does not affect the quality in each of the channels as both of them work on completely different bandwidths. How Broadband Works A broadband connection works on the Digital Subscriber Line system. In this system, the internet signals are sent through the telephone cable on a completely higher frequency. Indian ISPs mostly use ADSL (Asymmetric DSL) system. In this type of system, the uplink and downlink bandwidths are different. The downlink is always much more than the uplink one. Bandwidths: Indian service providers give a bandwidth with starts from 256 kbps and at the most they give it to 4 Mbps. This bandwidth is very low as compared to the other developed countries where the bandwidth goes to around 7-50 Mbps. In Sri Lanka itself, the minimum broadband bandwidth is 8 Mbps. India has a lot to go in this context. Modems: Currently, Indian markets have two types of modems: Type-1 ADSL Modems: These are the LAN cable connection modems. These types of modems are used for wired connections. These modems modulate and demodulate the internet packet signals at the uplink and downlink frequency. These modems are connected to the computers through an 8-wire LAN cable. These modems have a strong security system. The reason is that these modems can be connected only through a cable. As such, the unauthorised access can be prevented. Most of the ISPs provide the modems with the service. The chief brands of Type-1 modems available in the market are: Huawei- Its a Chinese brand, the cheapest and the least reliable. It costs in the range of around Rs 1200. This is not a good brand, YET BSNL is providing these modems to maximise its profit. D-Link- This is a Taiwan made brand, comparatively better. It has some added security features like PSK. The cost is around Rs. 1400. UT STARCOM- this is one of the best brands of this type of modems available here. It is totally user customisable, has an upgradable firmware system and the host security features. It costs around Rs. 1500. Type-2 ADSL Modems- These types of modems are the WLAN enabled modems. These modems are comparatively less secure as the other counterparts, but are more easy to use as well as they comprise a wireless broadband network. They are sometimes also called as Wi-Fi routers. They have a range of around 100 metres of wireless LAN communication. They can connect a maximum of 20 computers to the maximum. The chief brands available are: D-Link- as discussed earlier, this type of modem has better security features. Costs around 2000 Rs. UT STARCOM- This is the best brand. Costs around 2400 Rs. Has a totally upgradable firmware system. Plus, this is the only modem in the category which gives a 3-level security. These levels are: Admin level: Admin can access, edit, reset, change, and control all the other terminals. User Level: They can just access the main security module, but can change, edit or reset their own module only. Support Level: it has equal privileges of an Admin, but only with his permission. WIRELESS BROADBAND: This is the newest entry in the segment of public sector broadband connection. In this type of broadband, the ISPs provide the broadband over the mobile telephone frequency channels. A SIM card is given to the user, which can be inserted in the simcard slot of the laptop of the user, or he can purchase a USB modem which is configured for the purpose. Currently Reliance, Aritel, Tata Photon and BSNL are in this market. This type of broadband is mostly costly, and the speeds vary from 256 kbps-1Mbps at the most. This is usually not value for money. Reason being a typical plan costs from Rs. 700-3000, which is too costly for a normal user. The costs of USB modems are also very high. As per 18/10/10, the prices are: BSNL- Rs.3400 for modem, and plans start from Rs.300 Reliance- 2800 for the modem and plans start from 500. Tata- 2400 for the modem, plans start from 350. Airtel- 3000 for the modem, plans start from Rs. 900. So, we can imagine that the plans are too costly for the reach of common man. This is the main reason why this segment is not so popular with the people. 3G communication in mobile pioneered by BSNL has brought a cheaper version of mobile broadband. This has achieved a bandwidth of maximum of 512 kbps and still has a scope of improvement. The best advantage is that the Plans start from just Rs. 25. THE FUTURE- OPTICAL FIBRES This channel of the internet communication is still not available in the public domain. Optical fibres work on the principal of the modulation of signal with the carrier frequencies of that of the spectrum of light. Light travels at the speed of 3108 m/s. as such, the data transfer in this case would be at a very high speed. This channel of transmission has not even been utilised to calculate its limits. The reason behing this is that we do not have such equipments that can transmit at such a high speed. Till date, data has been transferred through this channel at a maximum speed of 4 Gbps (gigabits per second). This is still a fraction of its limit. A single OFC can transmit thousands of channels without a single noise. Also, this channel has a negligible resistance. As such, data loss rates are very very low. It has been estimated that the OFCs can transmit internet at the speed of around 40 Tbps (tera bits per second). This is still an estimate. The original figure may go even higher. Currently, no public sector company in India is providing the OFC internet. Only the defence forces (Indian Army and Air Force) are using it. Limiting factors in the use of OFC: The reason that the OFC internet communication system is still in the pipleine is that the technology needed to harness this channel speed to the maximum is still not available. Light travels at a speed of 300000000 m/s. if the signals are modulated to the suitable carrier, then the signal travelling at such a fast speed would practically give a really fast communication. How internet has changed our lives? Today we are living in 21st century i.e. In science era. Science and technology has modernised our lives and has made our life full of comforts. Means of Telecommunication and means of transportation are really a god gift for us..we cant imagine our lives without internet, television, etc. Internet has brought us together. It has united the wider gulfs across the oceans. we can have our access to any other part of world by just sitting at our home. It provides us various facilities. A student can have its access to internet as well as a person working can also use this internet in its own way. It is beneficial for all. Communication: We used to write letters to stay in touch with those far away, and if our correspondent was very special, we would use our trusty film camera to take some photos before taking the resultant film to the camera shop for developing waiting anywhere from an hour to a week to get the prints. Wed then hand over the cash, go home, put everything in the envelope, stick a stamp on it and post it off. Nowadays, we grab our digital camera, take as many shots as we want, upload them directly on to our PCs, attach a copy to an e-mail and send it off into the ether. We can store, share, and order prints for our photographs from the same service. Google, Yahoo, Facebook, Twitter and countless other websites have made social networking as easy as it could be. One cannot be too far away from his near and dear ones. People from all age groups spend time over these sites. Not only this, celebrities, VIP dignitaries, government officials etc. have their own portals on sites like twitter. Blogging is the trend of the new generation and with the help of your blog, you can share your likes and dislikes with the world . Reservation , banking : Now Internet can be also used for banking , reservation purposes . You can operate your bank account from your pc, view the account reports, report etc. by just sitting at your home . Even Railway and Airline reservation can be done with the help of   a click . Now there is no need to stand in queues and wait . Just open the site, click and book and your work is done.   Even shopping can be done by sitting at a desktop. Business: Internet is also used for expanding your business by the help of a website . Now you can target a large variety of consumers from around the world for your business if you have a properly maintained website. Various sites provide the online shopping facilities like www.ebay.in, www.tradus.in etc. Just a matter of click, and we can buy all what we want.

Who Is Raising the Children?   Ã‚  Ã‚  Ã‚  Ã‚  Children are no longer being raised by effective positive influences. Most parents don't have sufficient time to spend with their kids because of economic realities. They are relying on other resources to be positive figures. As well as parents, educators also lack the time and resources to positively influence students in their care. This lack of guidance is resulting in a generation of children without a sense of proper behavior and morale.   Ã‚  Ã‚  Ã‚  Ã‚  Most parents are forced to limit the amount of time they can spend with their children. Our economy may be the largest factor that separates parents from their kids. In single parent homes, the parent often has to work two jobs to support their family. Even when children are living with two parents, often both must work full time jobs. By simply trying to achieve minimal income, parents don't have enough time to dedicate strictly to their children.   Ã‚  Ã‚  Ã‚  Ã‚  Parents are having to rely on other resources to develop their child's mind. All too often, television has become the new baby-sitter for today's youth. This generation of children is watching more hours per day than any generation before it. In order to achieve higher ratings and a larger audience, television is pushing the limits of behavior and morality. When children are left with television as their main influence, a child does not receive a proper sense of reality. Th...

The Theme of Masculinity in Shakespeare’s play, Macbeth :: GCSE Coursework Macbeth

The Theme of Masculinity in Macbeth  Ã‚  Ã‚   In Shakespeare’s play, Macbeth‚ the theme of masculinity is explored. As Macbeth matures‚ there are times when his masculinity is put to the test, mostly after the murder of Duncan. There are four main themes in which masculinity is presented in the play. It was once considered that the more bloodthirsty and violent you were, the more manly you would be considered. Patriotism was regarded as a very masculine pathway and to die in battle for your cause, or better, for your country was in some ways a great act of heroism and a honourable way to die‚. This is one of the main themes of masculinity explored in Macbeth and can be illustrated by the simple quote of the man who will soon cold-bloodedly kill Banquo. The question put forth by Macbeth is whether the murderer will try and be a good Christian. He believes that to kill another man will make him more of a man and replies, We are men, my liege.‚ We can see patriotism active in the play when Siward seems unmoved by the news of the death of his son brought to him by Ross. Pleased in the knowledge that his son died an honourable man, fighting for his cause, he is happy because, knowing that his sons wounds were on his chest, he knows his son was not killed running away. If that was the case, Siward would not of though of his own son so highly. But like a man he died‚ There is a point where one cannot do anything that will make one more of a man‚ is a concept that Macbeth argues, indirectly, in the play. He thinks that after the murder of Duncan, which is wife thought made him a great man, there is nothing that he could do to be more of a man‚, Macbeth believes that he has done the ultimate deed, and that to do anything else to try to prove yourself would just be wrong because it would overshadow the deed that was done before it. I dare do all that may become a man; Who dares do more is none.‚ In Lady Macbeth‚s eyes if Macbeth did not kill Duncan than he would not be a man to her anymore, she believes that he would be denying all urges for greater wealth and prosperity that man should have. She is wondering why he is not taking the opportunity to be king when he can easily do so, in reality, we know why Macbeth is contemplating the murder of Macbeth, because he has morals, qualities that we consider manly today.

The Appeal Of The Androgynous Man :: essays research papers

â€Å"The Appeal of the Androgynous Man† This article was published in Mademoiselle in 1976 for young female readers by Amy Gross. In this article Gross compares androgynous men to the all-man man. Gross talks about the advantages of the androgynous man as compared to the all-man man. There are advantages and disadvantages to every man. Seems as though Gross is in favor of the androgynous man and she tends to bash the all-man man. Gross describes the Androgynous man as being a self-amused, less inflated, more quirky, vulnerable and responsive man. Gross describes the all-man man as being a male chauvinist and possessing none of the characteristics of the androgynous man. These descriptions are of men that Gross had encounters with, not necessarily every man in the world. It is evident through her descriptions that she is more in favor of the androgynous man and sees them as a better mate. The androgynous man maybe be a better mate for Gross, however this does not mean he is a better mate for every woman. Further Gross explains the results of an experiment done with college students that were categorized as masculine, feminine, or androgynous. This experiment tests the degree of nurturing and caring abilities of each person within the experiment. Gross makes it a point to reveal that masculine men scored low and gave her sympathy for anyone stuck with this type of man. The choice of what type of man a woman chooses to spend her life with is left up to the individual woman. If a masculine man makes a woman happy who is Gross to giver her sympathy to this woman. Gross stereotypes the all-man man by suggesting that the all-man man will reject behaviors and interests that are considered feminine. This stereotyping is based on her experience with men, not by the experience of women as a whole. Gross is making a misleading statement about men, therefore she is possibly misleading her readers. Young adult women need to take a look at their own needs and choose a man that will fulfill those needs, regardless of whether it be an androgynous man or an all-man man.

Petrarch and Wyatt Compared

In the world of poetry, imitation occurs at every turn. Many poets will take an original form of poetry and copy the style. This can be said about Sir Thomas Wyatt who attempts to mimic Petrarch's form; when the symbols, tone, images, rhyme, and setting in Wyatt's poem â€Å"Whoso list to hunt† are compared to Petrarch's Rime 190 it becomes apparent that he failed to embody the essence of Petrarch in his writing. Symbolism plays a large role in most poems. â€Å"A pure-white doe in an emerald glade/Appeared to me, with two antlers of gold† (Petrarch lines 1-2) is a perfect example of symbolism is poetry. Petrarch is not actually talking about a white deer with golden antlers, he's talking about a beautiful woman with golden hair. Wyatt also uses a deer as a symbol: â€Å"Whoso list to hunt, I know where is an hind† (Wyatt line 1) a hind is a deer and Wyatt is also using the deer as a symbol for a woman. This is the first similarity, or imitation, between Wyatt and Petrarch. The second symbolism the two poems share is the collar around the doe's neck. In Petrarch's poem it says â€Å"I spied on her neck, â€Å"No one dares touch me†,/Graven in topaz and diamond stones,/†For Caesar wills I should always run free. † (Petrarch lines 9-11). In Wyatt's poem it says: â€Å"And graven in diamonds in letters plain/There is written, her fair neck round about,/†Noli me tangere, for Caesar's I am,/And wild to hold, though I seem tame† (Wyatt lines 11-14). The two are similar only in the idea of a collar and Caesar. Petrarch's doe's collar claims she is free while Wyatt's doe's collar claims she is property. Although many strive to assimilate famous poets, sometimes they fall flat. Such is the case of Sir Thomas Wyatt's attempt to parallel Petrarch's tone. In Petrarch's Rime 190, the tone is reverence towards a woman's purity and beauty in the lines â€Å"A snow white doe in an emerald glade/To me appeared, with antlers soft of gold† (Petrarch lines 5-8). Wyatt's tone is more of sexual desire for an unavailable good looking woman who isn't necessarily pure: â€Å"Whoso list to hunt, I know where is an hind† (Wyatt line 1) hints that this woman is chased by a large amount of men for her looks (also hinting that she isn't pure); â€Å"But as for me, helas! I may no more† shows Wyatt's sexual desire for this woman and his disappointment in her unavailability to him. Petrarch's woman is a pure and beautiful woman while Wyatt's is a sexy, impure temptress. Another aspect Wyatt did not compare to Petrarch is visual imagery. Petrarch has a very beautiful way of using visual images which he proves with the lines one through four: â€Å"A snow white doe in an emerald glade/To me appeared, with antlers soft of gold,/And leapt two streams, under a laurel's shade,/Near sunrise, in the winter's bitter cold. (Petrarch lines 1-4). The closest visual image in Wyatt's version is â€Å"And graven in diamonds in letters plain† (Wyatt line 11) which is still very far away from being good visual imagery. Rhyme is a defining point of Petrarch's poetry with a rhyme scheme of abba abba cde cde. Wyatt kept the rhyme scheme of the octave but changed the sestet to cdd cee. â€Å"There is written, her fair neck round about,/Noli me tangere, for Caesar's I am,/And wild to hold, though I seem tame. (Wyatt line 12-14) is an example of the changed rhyme scheme. Wyatt also resorted to eye-rhyme which is also shown in the quotation for the words am and tame. Petrarch's poems held firm to the original rhyme scheme of abba abba cde cde and each rhyme is a complete rhyme rather than Wyatt's lazy eye-rhyming. Petrarch's rhyme scheme, however, is almost always only visible in the Italian form and it loses rhyme scheme when translated into English. Una candida cerva l'erba/Verde m'apparve, con duo corna d'oro/Fra due riviere, all'ombra d'un alloro,/Levando ‘l sole, a la stagione ascerba† (Petrarch line 1-4) this Italian passage from the poem follows the abba format of rhyming with perfect rhymes which his whole poem follows without using a single eye-rhyme. The setting of Petrarch's Rime 190 is beautifully described in the very first stanza: â€Å"A snow white doe in an emerald glade/To me appeared, with antlers soft of gold,/And leapt two streams, under a laurel's shade,/Near sunrise, in the winter's bitter cold. (Petrarch lines 1-4). The reader automatically knows that the poem takes place in a forest with two streams. On the other hand, Wyatt's poem has no setting to show for. There are almost no descriptive aspects of his poem. After analyzing these five aspects of poetry, it becomes clear that Wyatt's imitation of Petrarch only goes so deep. Wyatt merely used Petrarch's ideas but failed to perfect Petrarch's unique and beautiful language; where Petrarch shows beauty, Wyatt shows nothing. Wyatt took a pure form and warped it into something not as good as the original.

English literature exam paper Essay

†¢How does the writer present her thoughts and feeling about the struggle for identity? †¢How far is the extract similar to and different from your wider reading about the struggle for identity in modern literature? You should consider the writers’ choices of form, structure and language as well as subject matter. Betty Friedan has started her speech with two rhetorical questions, â€Å"Am I saying that women have to be liberated from men? That men are the enemy?† She is encouraging her audience to think about what her feelings are exactly. She quickly answers her own question, â€Å"No.† Within the first two sentences she has already got her audience to think about her views and their response to that. This was a good way to get her audience intrigued about the content of the rest of her speech. Her first paragraph is a basic overview of her feelings on the modern’s women’s movement. This way she can develop her points further in the rest of her speech. Throughout her speech, Friedan uses very negative language to describe men and their actions. For example, forced, suppressed, brutal etc. This shows that she has very negative views towards men and isn’t afraid to share this. She uses this pessimistic language to show how men have been holding back women and their struggle for identity. She says â€Å"men are going to bear the guilty burden of the passive destiny they have forced upon women,† The word forced is quite a harsh and aggressive word and this shows how she feel women have been treated by the other sex. She uses the metaphor of men and women being half human because of certain things holding them aback. For example, â€Å"Men are not allowed to cry.† And â€Å"as women are only half-human, until we can go this next step forward.† This shows that women can’t feel whole or complete until she is equal with men. The metaphor is carried on in the last paragraph but that when women are finally â€Å"allowed to become full people† that the next generations will live in a better wo rld. The word â€Å"allowed† suggest that she feels women are being suppressed by men or another controlling factor. Friedan says in the last paragraph â€Å"relate to each other in terms of all of the possible dimensions of our personalities – male and female, as comrades, as colleagues, as friends, as lovers.† Firstly she shows that they are separate as she disconnects by separating the genders, â€Å"male and female†. However, she then describes both the male and female population together â€Å"as comrades†. The word â€Å"comrades† have military connotations. This shows that men and women could work together in something that is seen as so masculine as the army. She then describes them â€Å"as colleagues†. This follows on from being comrades. If they can work together efficiently together in the military then they can handle working together in everyday jobs as equals. The effect of the whole list is that they are different (different genders) but are equal. She shows the struggle that women face in everyday life, â€Å"hate and jealousy and buried resentment and hypocrisies,† These words all help to show how negatively the way women are being treated is seen. Friedan then goes on to explain what life will be after men have learnt to except that women are people to, â€Å"there will be a whole new sense of love that will make what we call love on Valentine’s Day look very pallid.† There is two ways to look at this. Firstly, Valentine’s Day is meant to be the one day in the year where you show how much you love someone, this can show how much gaining an identity means to the women and what it will do to the world. However, one could argue that Valentine’s Day is only one day a year and so the changes could only be semi permanent. The whole speech from Betty Friedan is all about women’s struggle for identity. In Death of a Salesman, by Arthur Miller, there are subtle hints about the same issue. For example, at the end of Act One Biff and Happy are talking to Willy about getting some money and starting up a business together, Linda is also in the room. Linda tries to speak, â€Å"Maybe things are beginning to –â€Å" and Will ironically interrupts her and says â€Å"Stop interrupting,† Throughout the play Willy is putting Linda down even though she is the only person in the family that is really concerned about Willy’s health. However, we can see that in the play Willy represents the older generations views on women and Biff has the more modern and just outlook on it which represents the younger generation. This is shown again at the end of Act One. Linda starts to speak again and Willy interrupts her as he has done previously however this time Biff tells Willy â€Å"Don’t yell at her pop, will ya?† this shows how the women’s battle for identity has been paying off as the younger generations are starting to accept that this isn’t right. Betty Friedan foreshadows this in her speech when she says â€Å"children be born and brought up with more love and responsibility than today,† this shows what the modern population is going to grow up around. However, in Death of a Salesman we get the impression that Linda is essentially a housewife and is there to look after her family, mainly Willy, and to do domestic jobs around the house. This is fundamentally a typical role of women of the time. However, Betty Friedan seems to be saying that women are being active about changing the oppression that they are under. This difference in attitudes however could be to do with the age of the women and the modernity of them. For example the struggle for identity in the modern era can be different for different people. Because Linda is part of the older, less modern generation she is less likely to want to bring about change whereas Betty Friedan and the women she is talking about have more modern and equal views.
