When surmounting trouble rises, an optic fiber technician must choose the most suitable patch panel for a particular situation. That technician must recognize that when it comes to easy installation, proper termination and long term maintenance, not all patch panels are created equally. Optic fiber is robust and therefore deserves some special treatment. For example: if a horizontal copper cable is damaged, one user will be affected. If a backbone fiber goes down, it can take a lot of users down with it. This is why using fully enclosed connecting hardware for optic fiber is crucial. This is where the technician must choose between using wall-mounted or rack-mounted hardware. The optic fiber density required will most likely influence the technicians choice between the wall-mounted and rack-mounted connectivity. Many technicians will choose to use fiber patch cables. Trust your technician to know what's best.
Wall-mounted enclosures are suitable for up to 24 optic fibers, although with small form factors and high density connectors, can extend the fiber optic cable count to as many as 144. Wall-mount enclosures also offer the benefit of reduced floor space requirements. Rack-mounted optic fiber enclosures can be used with higher fabric counts or depending on the proximity to communications equipment, where rack-mounted optic fiber enclosures are preferable. 1U enclosures can handle up to 24 optic fiber cables with ST or SC connectors, or up to 48 optic fibers by using small form factor connectors. For extra protection, 2U to 4U enclosures can be used to handle up to 144 optic fiber connections.
A 12 fiber MPO connector can speed installation time and increase the concentration of connection hardware. The factory terminated and tested cassettes take care of breaking out the optic fibers from the MPO connectors to ST, SC, or MT-RJ connectors. The MPO cassettes can double the concentration that are possible in rack-mount enclosures - up to 72 optic fibers in a 1U enclosure and 288 optic fibers in a 4U enclosure - making these optic fibers perfectly fit to meet high density applications, such as data center's and storage area networks.
Accessibility is a concern for long term maintenance when choosing a rack-mount enclosure. The 1U enclosures may have a an access panel to reach the rear optic fibers, while larger enclosures may have a removable rear cover with adequate room inside to make changes or perform repairs. Strain relief and loop management for incoming cables must be provided, nonetheless management devices should be small enough as to not interfere with access to the optic fibers. Cable management for patch cords should be provided on the front of the enclosure with clear front covers and labeling arranged to ease moves, adds and changes and by ensuring that port identification is not obscured by patch cords.
Since copper patch panels need to be strong enough not to flex too much as the cables are punched down. The rolled edges on the panel sheet metal stock help to make the panels rigid. Copper patch panels should provide 24 ports in a 1U height or 48 ports in a 2U height. It's very important to make sure that the modular jacks and circuit traces on the panels are protected from debris that can short out circuits. All cable management systems must be easy to use and maintain to avoid any potential problems.

Fiber Patch Cables
Fiber patch cables are the backbone of the fiber optics industry. These fiber patch cables are strands of optically pure glass as thin as human hair. These cables carry information via mode of transmission of light. Short patch leads usually made with stranded wire are flexible patch cables. The fiber patch cables are used to plug one piece of equipment into another.
They have various uses in all kinds of industries. Fiber patch cables are used in medical imaging, mechanical engineering, LAN applications, cable TV networks, telephone lines, etc. Fiber patch cables have revolutionized the total network industry of telephones, cable, internet, audio applications, etc. The fiber patch cables offer accurate signal transfer which is totally distortion free. Thus due to these cables the audio or video transmission is completely distortion free and crystal clear. Since these fiber patch cables use light as a mode of transmission there is no hazard of electric interferences or any tampering.
Fiber patch cables are used to two nearby components with fiber connectors. Fiber patch cables come with their respective connectors. They can be an ideal and easy replacement of copper cables because they use the same RJ45 connector as copper patch cables.
Fiber patch cables are available in simplex, duplex, multimode, single mode with STST, STSC, SCSC connectors. Fiber patch cables are of two prominent types - single mode and multimode. Single mode fiber patch cables are used in long-distance high capacity voice applications like telephone transmission or long distance gigabit networking. These fiber patch cables can use 9/125 micron bulk fiber cables and connectors at both ends.
Multimode fiber patch cables are used in computer industry which is standard for data applications like local area network, wide area network, etc. Fiber patch cables in multimode are available in 50µm and 62.5µm. SC, ST, LC, FC, MT-RJ, E2000 and MU connectors have polished ceramic ferrules for precision and durability. The SC and LC duplex fiber patch cables come equipped with a clip to maintain polarity.
ST to ST fiber patch cable gives unlimited bandwidth at high speeds over long distances. These fiber patch cables are ideal for connections between fiber patch panels, hubs, switches, media converters and routers, etc. Fiber patch cables provide higher speeds and increased bandwidth, compared to conventional twisted-pair copper cable. These fiber patch cables are compatible with all standard fiber optic equipment and connectors. Ceramic connectors of these fiber patch cables ensure low signal loss and high reliability along with total immunity to electrical and electromagnetic interference.
Fiber patch cables are the most opted solution these days for the networking and broadcasting industry.

Fiber Optics Technology
The Principle of fiber optics is based on transmission of data by means of light. Concept of fiber optics was first conceived by Claude Chappe in 1790's. His idea for fiber optics was based on an optical telegraph concept invented by Graham Bell also tried the means to send information by the atmosphere but did not succeed. Finally, fiber optics emerged with the onset of new era based on the principle of total internal reflection which is a distinct quality of light rays.
Fiber optics emerged and grew into more advanced phase due to requirement from radio and telephone engineers. These engineers required more bandwidth for data transmission. Thus these engineers had been looking out for a medium to transmit data in more reliable and faster form rather than copper cables. They also wanted to avoid the hazards of electric shocks and interference which were a constant problem of copper cables.
Fiber optics attracted some attention because they were analogous in theory to plastic dielectric waveguides used in certain microwave applications. Finally a technology evolved that used glass or plastic threads to transmit data. Cables involved in fiber optics contain several bundles of glass threads which are capable of transmitting data in modulated form.
Understanding how fiber optics are made and function for uses in everyday life is an intriguing work of art combined with science. Fiber optics has been fabricated from materials that transmit light and are made from a bundle of very thin glass or plastic fibers enclosed in a tube. One end is at a source of light and the other end is a camera lens, used to channel light and images around the bends and corners. Fiber optics have a highly transparent core of glass, or plastic encircled by a covering called "cladding". Light is stimulated through a source on one end of the fiber optic and as the light travels through the tube, the cladding is there to keep it all inside. A bundle of fiber optics may be bent or twisted without distorting the image, as the cladding is designed to reflect these lighting images from inside the surface. This fiber optic light source can carry light over mass distances, ranging from a few inches to over 100 miles.
With the onset of fiber optics and fiber optic cables data started to transfer faster as fiber optic cables have greater bandwidth than metal cables and are more resistant to external interference. Lighter and thinner fiber optic cables readily transfer data in digital form rather than analogue form. This technology is most useful in computer industry which now forms an integral part of telephone, radio and television industry.
There are two kinds of fiber optics. The single-mode fiber optic is used for high speed and long distance transmissions because they have extremely tiny cores and they accept light only along the axis of the fibers. Tiny lasers send light directly into the fiber optic where there are low-loss connectors used to join the fibers within the system without substantially degrading the light signal. Then there are multi-mode which have much larger cores and accept light from a variety of angles and can use more types of light sources. Multi-mode fiber optics also use less expensive connectors, but they cannot be used over long distances as with the single-mode fiber optics.
Fiber optics have a large variety of uses. Most common and widely used in communication systems, fiber optic communication systems have a variety of features that make it superior to the systems that use the traditional copper cables. The use of fiber optics with these systems use a larger information-carrying capacity where they are not hassled with electrical interference and require fewer amplifiers then the copper cable systems. Fiber optic communication systems are installed in large networks of fiber optic bundles all around the world and even under the oceans. Many fiber optic testers are available to provide you with the best fiber optic equipment.
In fiber optic communication systems, lasers are used to transmit messages in numeric code by flashing on and off at high speeds. This code can constitute a voice or an electronic file containing, text, numbers, or illustrations, all by using fiber optics. The light from many lasers are added together onto a single fiber optic enabling thousands of currents of data to pass through a single fiber optic cable at one time. This data will travel through the fiber optics and into interpreting devices to convert the messages back into the form of its original signals. Industries also use fiber optics to measure temperatures, pressure, acceleration and voltage, among an assortment of other uses.
Fiber optics yield distortion free data transmission in digital form. The audio waves transmitted via principle of fiber optics deliver accurate signal transfer. Fiber optics is also useful in automotive and transportation industry. Traffic lights, organized and scrutinized highway traffic control, automated toll booths, etc. are some of the benefits of application of fiber options in the transportation mechanism.
Telecommunications applications of fiber optics use flexible low-loss fibers, using a single fiber per optical path. Along with the communication industry fiber optics plays an important role in medical and industrial applications also. Many medical appliances like endoscope use the principle of fiber optics. Industrial applications viz. in television industry use the principle of fiber optics to obtain flattened images in cathode ray tubes.
Cable TV companies and Internet Service Providers equivocally find fiber optics indispensable in their industry. Fiber optics provides tamper free, high bandwidth and larger data carrying capacity to the service providers. This eventually leads to better consumer satisfaction.
Unlike copper wire system fiber optics do not use and electrical form to carry data. The use of light gives a competitive edge to fiber optics over regular data transmission options. But eventually use of fiber optics is very expensive as compared to copper cabling system.

Importance of Wireless Network
Wireless networks provide an inexpensive and easy way to share a single Internet connection among several computers. This means you only need one modem, and you can add additional computers to the network just by plugging in a wireless card and turning them on. The new machines are connected to the Internet immediately.
A wireless network also lets you access files and printers from anywhere in your home. It allows you to synchronize files you have on your laptop with your home computer, and you can easily send files between computers as well. Using a wireless network to transfer files is faster than sending them via e-mail or burning them to a CD! Because printers connected to one of the computers on a network are shared by all the computers on that network, you can write documents anywhere in your home, press the ‘print' button, and collect the printed files from a printer that is connected to another computer.
If you are a game player, you've probably noticed that your games often have an option to play over a local area network or LAN. Wireless networks are LANs! This means you and your family can play these games together and don't have to be on computers that are next to each other to do so. Let's face it - it's more fun to play against real people, and it's even more fun to play against people you know instead of strangers on the Internet. Your games will also play much faster over your LAN. Additionally, you can connect game consoles to the Internet and begin playing these games online. It is much easier to experience online play through an Xbox or PlayStation 2 that is connected to a wireless network than have to use a modem!
Wireless network connections are always on. This means you can connect to the Internet whenever you want without waiting for your modem to dial in. Laptops can be carried from room to room, and they will always have access to the Internet. Since wireless networks operate without the need to log in, you don't need to set up usernames or passwords.
The single greatest thing about a wireless network is that it is, well, wireless! The biggest reason to have a wireless network is because it eliminates the need for costly, ugly, and dangerous wires trailing all over your house. You can use your computer in any room you want - no more being trapped near a phone outlet or walking over that tangle of wires in your home. The cost of getting enough Ethernet cables can add up, and sometimes, you may even have to make holes in your walls to set up a wired network. If you're renting, of course, this is impossible.
With a wireless network, you don't have these problems - you can even use your computer outside if you want! And if you move, there is no need to disconnect and pack up all those wires, and you no longer have to examine all the wires for damage whenever your Internet connection goes down.

Web-based Learning Management Systems
Learning management systems (LMSs) are web-based software application platforms used to plan, implement, and assess learning processes related to online and offline training administration and performance management. LMSs provide an instructor a way to create and deliver content, monitor learners' participation, and assess student performance. They also provide learners with the ability to use interactive features, such as threaded discussions, web conferencing, discussion forums, and other methods of communication.
In many respects, e-Learning has matured as a technology and industry. Today we will look at how web-based learning management systems can be and are being used as part of the partner support function in a company or organization.
Where and why are learning management systems being used in partner support settings?
LMSs are being used in business-to-business, high-process, value-added, and technology-oriented business environments in industries like telecommunications, advanced electronic technology, semiconductor manufacturing, insurance, banking, medical products, and others. Learning management systems are being used in partner support settings because they can be a cost-effective solution to providing performance support for a company's products and services.
In some ways, partner support operations may be similar to customer support settings, but they possess some distinct differences. More often than not, and by its very nature, a partner channel of distribution exists because the partner adds value to the product and services your company offers. Partner support operations may be more concerned with tactical distribution or other issues because they are responsible for providing their part of the value chain in the delivery of your product or service.
Partners walk a different road with product end users. Partners need the flexibility to provide information and support customer needs, but in a way that supports and amplifies the value their company brings to the partner channel.
Why is it cost-effective to use an LMS for your company's partner support operations?
Learning management systems have lots of functionality that can be used in partner support organizations. A good LMS lets you create multiple partner campuses, which the partners themselves can customize to meet an end-user customer's needs. Each partner can have their own look and feel, with a large selection of capabilities to deliver their unique value-add to the product or service.
Learning management systems can be used to create a library of custom online courses that demonstrate how to use products and services. These courses can be easily updated with the information/service offering unique to the partner's contribution to the product. They can have the same look and feel as the partner's site, to maintain a branded experience. The course can be updated at will, so you're not paying every three months to print new product guides and support manuals.
LMSs can be used to track and monitor your partner's activities, instead of using a bunch of spreadsheets. This is very effective in scenarios where partners must be certified to use your products and services. The learning management system can be set up to notify a partner when their certification is set to expire, using an email tickler so they can recertify on your product. The partner organizations themselves can be configured into a hierarchy within the learning management system, which can be used to manage the partner distribution channel.
What other features in learning management systems can be used for the partner support function?
A well-designed LMS comes with a help desk feature that can be used for 24/7 partner and end-user customer support. Learning management systems can have integrated web conferencing technology, which can be used in a number of ways to support partners and end-user customers Such as:
- synchronous training used in product implementation;
- web conferencing on a new feature set that can be archived for later viewing;
- actual, on-the-spot tech-support using the “share your desktop” feature so your tech can go in and fix any problems
LMSs can have a built-in survey tool that allows you to query your partners and end-user customers with the results stored in the learning management system database for later use. Learning management systems can have a single sign-on/e-Commerce registration feature that can be used to sell add-on features. LMSs also may have events management/seminar logistics add-on applications that can help you manage both your off-site and onsite partner and end-user customer support training. Each individual partner campus that is created can have its own reference area for materials, to help supplement online course content.
A company can realize effective resource planning and substantial cost savings by using learning management systems in partner support settings. The support offered through the functionality of a learning management system can go a long way to cement the relationship between the company and its partner distribution channel, and will have a direct impact on both organizations' bottom lines. Using a learning management system, one or two channel partnership managers or business development managers can manage and direct thousands of partner firms at substantially reduced costs, with the ability to provide precise support requirements customized to that partner's individual needs. In conclusion, web-based learning management systems can be a very useful, cost effective way to manage a company's partner support function.

Data Center
A data center is a facility that will house a good amount of the electronic equipment (and information) that a business or group has and needs. There will be computers and communication elements in this area as well as a number of other vital components to keeping the business running smoothly. What is essential about a data center is security and maintenance.
Companies may have more than one data center as well. Most mid size or higher companies will have at least one data center though. There are many types of data that can be stored in these centers. For example, a financial institution will maintain their clients accounts, numbers and activities in the data center. Businesses will keep client names, accounts, and projects in a data center as well. Because the data a business has is so very important to their existence and their performance, turning to a data center is an excellent option for this type of storage need.
Inside of a data center you are likely to find various types of computers, internet servers as well as many other items. To keep these items safe, data centers are often built and secured physically as well as logistically to protect them. Security is extremely high. They can be one of the safest environments in the city. The main job of a data center is to maintain and run applications to allow businesses to access and manage their files effectively.
There are many information portals now devoted to the subject and we recommend reading about it at one of these. Try googling for “data center info” and you will be surprised by the abundance of information on the subject. Alternatively you may try looking on Yahoo, MSN or even a decent directory site, all are good sources of this information.

High Definition Multimedia Interface (HDMI)
High definition multimedia interface (HDMI), is a type of audio and video interface that is used for the transmission of uncompressed digital streams. Essentially, HDMI can be considered an alternative method to transmitting data streams, rather than making use of conventional methods such as coaxial cabling, VGA, or component video equipment.
What Type of Sources May Be Employed Using HDMI?
Quite a number of devices and sources on the market today will work with the use of HDMI. The Blu-Ray disc player, a relatively new innovation, was created with the use of HDMI specifically in mind. Most personal computers that are sold today are ready for use with HDMI, as are the majority of video game consoles in the stores currently. A set-top box also is usually compatible with HDMI, as are such entertainment options as digital television. Essentially, any type of computer interface today will function with the use of HDMI.
How HDMI Works
HDMI will work with a single cable connection to such devices as televisions or personal computers. In general, HDMI will function fine with any television or PC that is standard, enhanced, or high definition in the video component. However, it is important to note that HDMI does work independently of many of the DTV standards, although use of HDMI will not impact the quality of the digital transmission. Generally, these standards apply to some configurations of MPEG movie clips and files. Since these are compressed, HDMI will simply decompress the data and make it possible to view the clip.
HDMI Versions And Devices?
No. There is a range of specifications that are employed by HDMI, and a given device will be manufactured to comply with one of those specifications. The most simplistic specification is identified as 1.0. With each succeeding version, the capabilities of the previous version remain intact, but are joined by other capabilities that will allow the version to function with a given device. Because technology is always advancing, HDMI continues to advance as well. However, older versions remain active, as they are often used with devices that require less functionality, and they also continue to be helpful in situations where older systems are still running and are in operation.
Where Did HDMI Come From?
HDMI was created and has been enhanced by the efforts of several prominent names in the computer and electronics industry. Consumers will recognize the names of Philips, Sony, Toshiba, and Silicon Image as just part of the roster of corporations involved in the ongoing enhancement of HDMI.
What Type of Sources May Be Employed Using HDMI?
Quite a number of devices and sources on the market today will work with the use of HDMI. The Blu-Ray disc player, a relatively new innovation, was created with the use of HDMI specifically in mind. Most personal computers that are sold today are ready for use with HDMI, as are the majority of video game consoles in the stores currently. A set-top box also is usually compatible with HDMI, as are such entertainment options as digital television. Essentially, any type of computer interface today will function with the use of HDMI.

Coping with Lyme Disease
If you've ever gotten Lyme disease from an infected tick bite, then you know how uncomfortable the illness can be. Some people don't realize just how frustrating and painful the disease can be for those suffering from it. Joint and muscle pain that lasts for days or weeks at a time, countless trips to the doctor's office, misdiagnoses and failed treatments all can make for an extremely stressful period of time.
Coping with Lyme disease can be particularly difficult because oftentimes the illness is misdiagnosed, which leads to treatment plans that don't work and ongoing sickness and pain from the disease. Because there is no conclusive test to determine whether or not a Lyme disease infection is present, misdiagnosis is common. This can be especially frustrating for people that are told that their symptoms are “all in their head” or that the symptoms are purely psychiatric and that they need anti-depressants. There are more than 100 different symptoms of Lyme disease, which can make it extremely difficult for doctors to narrow down the symptoms into one illness. The disease is also commonly misdiagnosed as another type of ailment, such as arthritis, and so the patient does not receive proper treatment.
If you are coping with Lyme disease in your life, following are some tips that may help you as you fight the disease:
Understand Lyme disease - Get familiar with the disease. Educate yourself on the basics of Lyme disease, such as its causes, symptoms, how it is diagnosed and prognosis. Lyme disease develops from the bacteria Borrelia, which is most commonly transmitted via the bite of a deer tick. Once the bacteria invade your body, you'll most likely begin to experience symptoms within a matter of weeks. Symptoms include a reddish bulls-eye shaped rash, fever, fatigue, and arthritis-like muscle and joint pain. Coping with Lyme disease and its symptoms certainly is not fun, but by examining your symptoms and medical history, your doctor will hopefully be able to make a proper diagnosis. Once a diagnosis is made, treatment can begin. This will most often include either oral or IV antibiotics to rid your body of the bacteria. Understanding the illness and how it affects your body is an important part of coping with Lyme disease.
Explore your treatment options - Talk to your doctor about different treatment that may be available. Antibiotics are most commonly used to fight the disease. However, there are alternative therapies available, although they have not been studied thoroughly during clinical trials and therefore may not be as effective.
Be patient - This is the hardest thing to do when you're feeling awful, but it's very important when coping with Lyme disease. You need to give your body time to heal and respond to treatments, and worrying or stressing over how long it's taking or dwelling on how bad you feel will NOT help you recover any faster. In fact, it's more likely to slow down your recovery. So just hang in there -- you will get better in time.

Controlling The Thought
Controlling thought. How would you like to be able to turn on your television just by thinking? Or have the door to your house open by mind power when your hands were full? This isn't something that will remain science fiction for long. The technology necessary to make this happen is here now.
First of all, you have basic thought control now, meaning you can control and direct your thoughts. You can imagine a friend talking in your mind, for example. Then you can choose to hear music in your imagination. If you are hooked up to an electroencephalograph when you do these things, it will also be clear that these two thoughts are handled in different parts of your brain.
This electroencephalogram, or EEG, is important, because what we can measure, we can use to do things. Think about this for a moment. Modern electronics has made it possible to easily operate things as a response to measurement. A thermostat measures the temperature, for example, and turns the heater on or off according to that measurement. Security lights turn themselves on when light levels get low.
Thought Control Devices
We can already measure and track what is going on in the brain. Is it inconceivable then, to have that measurement automatically trigger some action? For example, even before the electrical patterns of the brain were made "visible," we measured pulse rate with many different machines. Now, what if instead of sending a signal to a monitor telling a red light to go on when the heart raced, the signal told the TV to turn on? Think of anything that gets your heart racing and the TV would turn on, right?
Call it mind power, thought control or whatever. You can see that such a device has been possible for at least a generation now. With new technology, and more detailed measurements of the actual electric patterns of the brain, how much more is possible?
Someday, an electroencephalograph type of device will be able to more directly read your mind. The technology will eventually get to the point where it can print out the actual words you are thinking. We are a long way from that, but we are right at the brink of building machines that give us thought control of the things around us.
You see, even with the crude measurements being done now, as long as we can choose what to think about, and any resulting change in the brain can be measured, the possibilities are endless. For example, we can already see the changes in the brain when a person thinks about music, versus a conversation. An existing electroencephalograph machine, using electrodes attached to your head, could be set to turn on the lights instead of producing a changing chart when you sing in your mind.
For paraplegics without speech, there's real hope in this idea. A patterned alternating of thoughts could be used as a sort of Morse code, spelling out words on a screen. They could actually use thought control to make a message appear! At the current level of technology, this would be a tedious process, but the amazing thing is that all the necessary things to build a machine like this are here right now. It's time for thought control.

Eugenics and the Future of Human Species
"It is clear that modern medicine has created a serious dilemma ... In the past, there were many children who never survived - they succumbed to various diseases ... But in a sense modern medicine has put natural selection out of commission. Something that has helped one individual over a serious illness can in the long run contribute to weakening the resistance of the whole human race to certain diseases. If we pay absolutely no attention to what is called hereditary hygiene, we could find ourselves facing a degeneration of the human race. Mankind's hereditary potential for resisting serious disease will be weakened."
Jostein Gaarder in "Sophie's World", a bestselling philosophy textbook for adolescents published in Oslo, Norway, in 1991 and, afterwards, throughout the world, having been translated to dozens of languages.
The Nazis regarded the murder of the feeble-minded and the mentally insane - intended to purify the race and maintain hereditary hygiene - as a form of euthanasia. German doctors were enthusiastic proponents of an eugenics movements rooted in 19th century social Darwinism. Luke Gormally writes, in his essay "Walton, Davies, and Boyd" (published in "Euthanasia Examined - Ethical, Clinical, and Legal Perspectives", ed. John Keown, Cambridge University Press, 1995):
"When the jurist Karl Binding and the psychiatrist Alfred Hoche published their tract The Permission to Destroy Life that is Not Worth Living in 1920 ... their motive was to rid society of the 'human ballast and enormous economic burden' of care for the mentally ill, the handicapped, retarded and deformed children, and the incurably ill. But the reason they invoked to justify the killing of human beings who fell into these categories was that the lives of such human beings were 'not worth living', were 'devoid of value'"
It is this association with the hideous Nazi regime that gave eugenics - a term coined by a relative of Charles Darwin, Sir Francis Galton, in 1883 - its bad name. Richard Lynn, of the University of Ulster of North Ireland, thinks that this recoil resulted in "Dysgenics - the genetic deterioration of modern (human) population", as the title of his controversial tome puts it.
The crux of the argument for eugenics is that a host of technological, cultural, and social developments conspired to give rise to negative selection of the weakest, least intelligent, sickest, the habitually criminal, the sexually deviant, the mentally-ill, and the least adapted.
Contraception is more widely used by the affluent and the well-educated than by the destitute and dull. Birth control as practiced in places like China distorted both the sex distribution in the cities - and increased the weight of the rural population (rural couples in China are allowed to have two children rather than the urban one).
Modern medicine and the welfare state collaborate in sustaining alive individuals - mainly the mentally retarded, the mentally ill, the sick, and the genetically defective - who would otherwise have been culled by natural selection to the betterment of the entire species.
Eugenics may be based on a literal understanding of Darwin's metaphor.
The 2002 edition of the Encyclopedia Britannica has this to say:
"Darwin's description of the process of natural selection as the survival of the fittest in the struggle for life is a metaphor. 'Struggle' does not necessarily mean contention, strife, or combat; 'survival' does not mean that ravages of death are needed to make the selection effective; and 'fittest' is virtually never a single optimal genotype but rather an array of genotypes that collectively enhance population survival rather than extinction. All these considerations are most apposite to consideration of natural selection in humans. Decreasing infant and childhood mortality rates do not necessarily mean that natural selection in the human species no longer operates. Theoretically, natural selection could be very effective if all the children born reached maturity. Two conditions are needed to make this theoretical possibility realized: first, variation in the number of children per family and, second, variation correlated with the genetic properties of the parents. Neither of these conditions is farfetched."
The eugenics debate is only the visible extremity of the Man vs. Nature conundrum. Have we truly conquered nature and extracted ourselves from its determinism? Have we graduated from natural to cultural evolution, from natural to artificial selection, and from genes to memes?
Does the evolutionary process culminate in a being that transcends its genetic baggage, that programs and charts its future, and that allows its weakest and sickest to survive? Supplanting the imperative of the survival of the fittest with a culturally-sensitive principle may be the hallmark of a successful evolution, rather than the beginning of an inexorable decline.
The eugenics movement turns this argument on its head. They accept the premise that the contribution of natural selection to the makeup of future human generations is glacial and negligible. But they reject the conclusion that, having ridden ourselves of its tyranny, we can now let the weak and sick among us survive and multiply. Rather, they propose to replace natural selection with eugenics.
But who, by which authority, and according to what guidelines will administer this man-made culling and decide who is to live and who is to die, who is to breed and who may not? Why select by intelligence and not by courtesy or altruism or church-going - or al of them together? It is here that eugenics fails miserably. Should the criterion be physical, like in ancient Sparta? Should it be mental? Should IQ determine one's fate - or social status or wealth? Different answers yield disparate eugenic programs and target dissimilar groups in the population.
Aren't eugenic criteria liable to be unduly influenced by fashion and cultural bias? Can we agree on a universal eugenic agenda in a world as ethnically and culturally diverse as ours? If we do get it wrong - and the chances are overwhelming - will we not damage our gene pool irreparably and, with it, the future of our species?
And even if many will avoid a slippery slope leading from eugenics to active extermination of "inferior" groups in the general population - can we guarantee that everyone will? How to prevent eugenics from being appropriated by an intrusive, authoritarian, or even murderous state?
Modern eugenicists distance themselves from the crude methods adopted at the beginning of the last century by 29 countries, including Germany, The United States, Canada, Switzerland, Austria, Venezuela, Estonia, Argentina, Norway, Denmark, Sweden (until 1976), Brazil, Italy, Greece, and Spain.
They talk about free contraceptives for low-IQ women, vasectomies or tubal ligations for criminals, sperm banks with contributions from high achievers, and incentives for college students to procreate. Modern genetic engineering and biotechnology are readily applicable to eugenic projects. Cloning can serve to preserve the genes of the fittest. Embryo selection and prenatal diagnosis of genetically diseased embryos can reduce the number of the unfit.
But even these innocuous variants of eugenics fly in the face of liberalism. Inequality, claim the proponents of hereditary amelioration, is genetic, not environmental. All men are created unequal and as much subject to the natural laws of heredity as are cows and bees. Inferior people give birth to inferior offspring and, thus, propagate their inferiority.
Even if this were true - which is at best debatable - the question is whether the inferior specimen of our species possess the inalienable right to reproduce? If society is to bear the costs of over-population - social welfare, medical care, daycare centers - then society has the right to regulate procreation. But does it have the right to act discriminately in doing so?
Another dilemma is whether we have the moral right - let alone the necessary knowledge - to interfere with natural as well as social and demographic trends. Eugenicists counter that contraception and indiscriminate medicine already do just that. Yet, studies show that the more affluent and educated a population becomes - the less fecund it is. Birth rates throughout the world have dropped dramatically already.
Instead of culling the great unwashed and the unworthy - wouldn't it be a better idea to educate them (or their off-spring) and provide them with economic opportunities (euthenics rather than eugenics)? Human populations seem to self-regulate. A gentle and persistent nudge in the right direction - of increased affluence and better schooling - might achieve more than a hundred eugenic programs, voluntary or compulsory.
That eugenics presents itself not merely as a biological-social agenda, but as a panacea, ought to arouse suspicion. The typical eugenics text reads more like a catechism than a reasoned argument. Previous all-encompassing and omnicompetent plans tended to end traumatically - especially when they contrasted a human elite with a dispensable underclass of persons.
Above all, eugenics is about human hubris. To presume to know better than the lottery of life is haughty. Modern medicine largely obviates the need for eugenics in that it allows even genetically defective people to lead pretty normal lives. Of course, Man himself - being part of Nature - may be regarded as nothing more than an agent of natural selection. Still, many of the arguments advanced in favor of eugenics can be turned against it with embarrassing ease.
Consider sick children. True, they are a burden to society and a probable menace to the gene pool of the species. But they also inhibit further reproduction in their family by consuming the financial and mental resources of the parents. Their genes - however flawed - contribute to genetic diversity. Even a badly mutated phenotype sometimes yields precious scientific knowledge and an interesting genotype.
The implicit Weltbild of eugenics is static - but the real world is dynamic. There is no such thing as a "correct" genetic makeup towards which we must all strive. A combination of genes may be perfectly adaptable to one environment - but woefully inadequate in another. It is therefore prudent to encourage genetic diversity or polymorphism.
The more rapidly the world changes, the greater the value of mutations of all sorts. One never knows whether today's maladaptation will not prove to be tomorrow's winner. Ecosystems are invariably comprised of niches and different genes - even mutated ones - may fit different niches.
In the 18th century most peppered moths in Britain were silvery gray, indistinguishable from lichen-covered trunks of silver birches - their habitat. Darker moths were gobbled up by rapacious birds. Their mutated genes proved to be lethal. As soot from sprouting factories blackened these trunks - the very same genes, hitherto fatal, became an unmitigated blessing. The blacker specimen survived while their hitherto perfectly adapted fairer brethren perished ("industrial melanism"). This mode of natural selection is called directional.
Moreover, "bad" genes are often connected to "desirable genes" (pleitropy). Sickle cell anemia protects certain African tribes against malaria. This is called "diversifying or disruptive natural selection". Artificial selection can thus fast deteriorate into adverse selection due to ignorance.
Modern eugenics relies on statistics. It is no longer concerned with causes - but with phenomena and the likely effects of intervention. If the adverse traits of off-spring and parents are strongly correlated - then preventing parents with certain undesirable qualities from multiplying will surely reduce the incidence of said dispositions in the general population. Yet, correlation does not necessarily imply causation. The manipulation of one parameter of the correlation does not inevitably alter it - or the incidence of the outcome.
Eugenicists often hark back to wisdom garnered by generations of breeders and farmers. But the unequivocal lesson of thousands of years of artificial selection is that cross-breeding (hybridization) - even of two lines of inferior genetic stock - yields valuable genotypes. Inter-marriage between races, groups in the population, ethnic groups, and clans is thus bound to improve the species' chances of survival more than any eugenic scheme.

Modern eugenics relies on statistics. It is no longer concerned with causes - but with phenomena and the likely effects of intervention. If the adverse traits of off-spring and parents are strongly correlated - then preventing parents with certain undesirable qualities from multiplying will surely reduce the incidence of said dispositions in the general population. Yet, correlation does not necessarily imply causation. The manipulation of one parameter of the correlation does not inevitably alter it - or the incidence of the outcome.
Eugenicists often hark back to wisdom garnered by generations of breeders and farmers. But the unequivocal lesson of thousands of years of artificial selection is that cross-breeding (hybridization) - even of two lines of inferior genetic stock - yields valuable genotypes. Inter-marriage between races, groups in the population, ethnic groups, and clans is thus bound to improve the species' chances of survival more than any eugenic scheme.
Building a Robot
A robot could make life easier for you if you know how to build one. Robots as we all know are considered as friendly creature created by human beings as we are created by God. They are created for human being to simplify life even more basically for our daily chores with the specified sequence and even by military for the purpose of doing things which has the danger to life of human beings and thus they are developed over years to substitute human beings in all the fields.
Many of us are not that qualified to make a robot by ourselves and that why we all are anxious to know how to make a robot and even depends upon the task we want to create it for. We all have the tendencies of exploring whatever new comes in the field of science and hence a basic prototype robot can be created knowing few basic high end programming stuffs.
Robots are almost 30% programming and hence if we target one specific purpose and program it well enough then it serves our purpose and the program mostly used for this is Unix and for beginner's Lego Mindstorms series is the best and how complicated your robot might turn up to be depends upon your technical acumen.
While learning how to make a robot we should always keep in mind that fewer the moving parts be of the robot better it is for the beginner's as for startup we might just want it to move from here and there or hold something and sort of stuff. We should link if-then statement well and it should be taken care of that battery is never less then 50% and if so happens it should be re charged.
Thus we now understand that knowing how to make robot can never be known as there is no limit to what can be achieved with the knowledge of science and development of robots can never end.

How to Build a Rocket
Rockets are very interesting machines. Rockets - They are one of the most enjoyable pyrotechnic devices. Small lightweight rockets can be made using Black powder, which is used popularly as rocket propellant and is easy to mix. We have explained the basic steps that can follow to make a simple rocket.
First make the black powder mix. Use Potassium Nitrate, Air Float Charcoal,80 Mesh Charcoal, Sulfur in the ratio of 16:6:3:4. This is a optimum mix ratio, grind all the mix into a container and make a fine free flowing powder. Pass it though a mesh preferably 20 Mesh steel mesh.
Take a 4 Oz Engine tube for making the Body of the rocket. Now ram the fine grained black powder mix into the tube up to 80% and a little air room. You can use a 'ram through funnel', which will make our task easy, the rammed materials inside the body of the rocket should be hard.
Now fill in clay after making it a little moist and fill it in the space where the room for air has been left. Now punch a thin hole in the clay using a thin object, say needle. This is for the fuse. A ready made fuse can be obtained from a firecracker or by coating a cotton string with the same black powder material.
Attach the fuse to the under part of the rocket body through the clay, also make a conical head of paper materials.
Now tape a long stick to the rocket for stability. The rocket is ready now, bury the stick in the sand upright and light the fuse, watch it skyrocket upwards.
