Ear buds/Earphones

Ear buds or earphones are headphones of a smaller size that are positioned directly outside of the ear canal, but without fully enveloping it. They are generally inexpensive and are favored for their portability and convenience. However, due to their inability to provide isolation, they are not capable of delivering the same dynamic range offered by many full-sized headphones and canal phones for a given volume level. As a result, they Are often used at higher volumes in order to drown out noise from the users surroundings, which increases the risk of hearing-loss.

A Personal portal

A Personal portal is a site on the World Wide Web that characteristically provides personalized capabilities to its visitors, given that a pathway to other content. It is intended to use distributed applications, different numbers and types of middleware and hardware to provide services from a number of different sources. In addition, business portals are intended to share collaboration in workplaces. A further business-driven requirement of portals is that the content be able to work on multiple platforms such as personal computers, personal digital assistants (PDAs), and cell phones.

Malai

Malai is a South Asian term for clotted cream or Devonshire cream. It is made by heating non-homogenized whole milk to about 80ºC (180ºF) for about one hour and then allowing to cool. A thick yellowish layer of fat and coagulated proteins forms on the surface, which is skimmed off. The process is typically repeated to remove most of the fat. Malai has about 55% butterfat. Buffalo milk is thought to produce better malai because of its high fat content.Malai is used in such recipes as Malai Kofta dumplings and the sweet Malai Kulfi.

Marketing

Marketing is one of the most significant functions in business. It is the regulation required to understand customers' needs and the benefits they seek. Academia does not have one commonly agreed upon description. Even after a better part of a century the dispute continues. In a nutshell it consists of the social and managerial processes by which goods or services and value are exchanged in order to fulfill the needs and wants of individuals or groups. Although many people appear to think that "marketing" and "advertising" are synonymous, they are not. Advertising is simply one of the lots of processes that together constitute marketing.

Canonization

Canonization is the act by which a Christian Church declares some deceased person to be a saint, inscribing that person in the canon, or list, of recognized saints.In the Catholic Church, the act of canonization is now kept to the Holy See and occurs at the conclusion of a long process requiring extensive proof that the person future for canonization lived, and died, in such a way that he or she is worthy to be recognized as a saint. at first, however, individuals were recognized as saints without any formal process, as happened, for instance, in the case of Saint Peter and the Blessed Virgin Mary. Other Christian Churches still follow the older practice Canonization, whether formal or informal, does not make someone a saint: it is only a declaration that the person is a saint and was a saint even before canonization. It is generally familiar that there are many more saints in heaven than have been canonized on earth.

Motorcycle

A motorcycle is a two-wheeled , single-track motor vehicle powered by an engine. Styles of motorcycles changes according to the task for which they are designed. Motorcycles are the most widespread the least expensive forms of motorised transport in many parts of the world. Street and off-road motorcycle are the two major type of motorcycle. Within these, there are many different types of motorcycles for many different purposes.Choppers,Cruisers,electric motorcycles,Mini bikes,Mopeds,Scooters etc are street motorcycle.Motocross,Supermotos,Dual-sports,Enduros are the off-road motorcycle.
A motorcycle is broadly defined by law in some countries for the purposes of registration, taxation or licensing riders as a two-wheel motor vehicle "fit to drive." Other countries distinguished between mopeds and other small bikes and the larger, more powerful vehicles.

Oily fish

Oily fish are those fish which have oils throughout the fillet and in the belly cavity around the gut, rather than only in the liver like white fish. Oily fish fillets may contain up to 30 percent oil, although this figure varies both within and between species. Oily fish generally swim in mid-waters or near the surface
Oily fish are a good source of Vitamins A and D as well as being rich in Omega 3 fatty acids. For this reason the consumption of oily fish has been identified as more beneficial to humans than white fish. Amongst other benefits, studies suggest that the Omega 3 fatty acids in oily fish may help sufferers of depression, reduce the likelihood of heart disease and improve inflammatory conditions such as arthritis.

Neem oil

Neem oil is a vegetable oil pressed from the fruits and seeds of Neem, an evergreen tree which is endemic to the Indian sub-continent and has been introduced to many other areas in the tropics. It is perhaps the most significant of the commercially available products of neem.Neem oil is typically light to dark brown, bitter and has a rather strong odour that is said to join the odours of peanut and garlic. It comprises mainly triglycerides and large amounts of triterpenoid compounds, which are in charge for the bitter taste. It is hydrophobic in nature and in order to emulisify it in water for application purposes, it must be formulated with suitable surfactants.Neem oil also contains steroids and a plethora of triterpenoids of which Azadirachtin is the most well known and studied. The Azadirachtin content of Neem Oil varies from 300ppm to over 2000ppm depending on the quality of the neem seeds compressed.

History of Europe

Europe has a long history of cultural and economic achievement, initial as far back as the Paleolithic. Genesis of Western democratic and individualistic cultures are often laid in Ancient Greece; the Roman Empire divided the continent along the Rhine and Danube for more than a few centuries. Following the decline of the Roman Empire, Europe entered a extended period of stasis, referred to by Renaissance thinkers as the "Dark Ages" and by the Enlightenment and modern historians, as the Middle Ages. During this time remote monastic communities in Ireland and elsewhere carefully safeguarded and compiled knowledge accumulated previously. The Renaissance and the New Monarchs marked the start of a period of discovery, exploration, and increase in scientific knowledge. From the 15th century Portugal opened the age of discoveries soon followed by Spain. They were shortly joined by France, Belgium, the Netherlands and Britain, in building large colonial empires, with vast holdings in Africa, the Americas, and Asia.

Extended Industry Standard Architecture

The Extended Industry Standard Architecture is a bus standard for IBM well-matched computers. It was announced in late 1988 by PC clone vendors as a counter to IBM's use of its proprietary Micro Channel Architecture in its PS/2 series.

EISA extends the ISA bus architecture to 32 bits and allows more than one CPU to share the bus. The bus mastering support is also improved to provide access to 4 GB of memory. Unlike MCA, EISA can accept older XT and ISA boards — the lines and slots for EISA are a superset of ISA.

Digital Circuits

Digital systems interface well with computers and are easy to control with software. It is often possible to add new features to a digital system without changing hardware, and to do this remotely, just by uploading new software. Design errors or bugs can be worked-around with a software upgrade, after the product is in customer hands. Information storage can be much easier in digital systems than in analog ones. In particular, the great noise-immunity of digital systems makes it possible to store data and retrieve it later without degradation. In an analog system, aging and wear and tear will degrade the information in storage, but in a digital system, as long as the wear and tear is below a certain level, the information can be recovered completely.

Jitter

The colloquial or historical meaning of jitter is to shake or shudder one's body or limbs. Also:” Jittery" synonymous with "nervous" or "tense" to the extent of shaking, usually implying fear rather than excitement. May involve a neurological seizure, or withdrawal symptoms from drunkenness - Delirium tremens. Also: jitterbug - a dance that involved shaking the arms and legs.

In electronics and telecommunications, jitter is an unwanted variation of one or more signal characteristics, such as the interval between successive pulses, the amplitude of successive cycles, or the frequency or phase of successive cycles. Jitter is a significant factor in the design of almost all communications links.

Jitter can apply to a number of signal qualities, and can be quantified in the same terms as all time-varying signals. Also like other time-varying signals, jitter can be expressed in terms of spectral density. Jitter frequency is the time between the maximum and minimum effect of a jitter characteristic for a jitter that varies frequently with time. Generally, very low jitter frequency is not of interest in designing systems, and the low-frequency cutoff for jitter is typically specified at 1 Hz.

In the context of digital audio extraction from CDs "jitter" causes extracted audio samples to be doubled-up or skipped entirely. The problem occurs because the Philips CD requirement doesn't require block-accurate addressing. As a result, the extraction process will restart a few samples early or late, resulting in doubled or omitted samples. These glitches often sound like tiny repeating clicks during playback. An approach that has produced good results is to do jitter correction in software. This involves performing overlapping reads, and then sliding the data around to find overlaps at the edges. Most DAE programs will perform jitter correction.

World Wide Web

The World Wide Web is a system of interlinked, hypertext documents that runs over the Internet. With a Web browser, a user views Web pages that may include text, images, and other multimedia and navigates between them using hyperlinks. The World Wide Web is the combination of four basic ideas: Hypertext, Resource Identifiers, The Client-server model of computing, Markup language. On the World Wide Web, a client program called a client agent retrieves information resources, such as Web pages and other computer files, from Web servers using their URLs. If the user agent is a kind of Web browser, it displays the resources on a user's computer. The user can then follow hyperlinks in each web page to other World Wide Web resources, whose position is embedded in the hyperlinks. Web pages are often set in collections of related material called Web sites. The act of following hyperlinks from one Web site to another is referred to as browsing or sometimes as surfing the Web.

Bullet

Bullet
A bullet is a solid shell propelled by a weapon or air gun and is normally made from metal. A bullet does not contain explosives, and damages the planned target solely by imparting kinetic energy upon impact. Modern bullets for firearms are usually part of a cartridge, also known as a round. In contrast, bullets for air guns are not part of a cartridge. The word "bullet" is sometimes used to refer to the combination of bullet, case, gunpowder and primer more properly known as a cartridge or round."

History

The history of bullets parallels the history of firearms. Advances in one either resulted from or precipitated advances in the additional. Originally, bullets are round metallic or stone balls placed in front of a volatile charge of gunpowder at the end of a closed tube. As firearms became more scientifically advanced, from 1500 to 1800, bullets changed very little. They remained simple round lead balls, called rounds, conflicting only in their diameter. The growth of the hand culverin and matchlock harquebus brought about the use of cast lead balls as projectiles. "Bullet" is derived from the French word "boulette" which approximately means "little ball". The original musket bullet was a globular lead ball two sizes smaller than the bore, wrapped in a loosely-fitted paper patch which served to hold the bullet in the barrel firmly upon the powder. The loading of muskets was, therefore, easy with the old smooth-bore Brown Bess and similar military muskets.

Lens construction

The majority type of lenses are spherical lenses, which are fashioned from surfaces that have spherical curvature, that is, the front and back surfaces of the lens can be anticipated to be part of the surface of two spheres of given radii, R1 and R2, which are called the radius of curvature of each surface. The sign of R1 gives the form of the front surface of the lens: if R1 is positive, the surface is convex. If R1 is negative, the front surface is concave. If R1 is infinite, the surface is flat, or has zero curvature, and is said to be plane. The same is true for the back surface of the lens; apart from that the sign conversion is reversed: if R2 is positive, it is concave, and if R2 is negative, the back surface is convex. The line joining the centers of the spheres making up the lens surfaces is called the axis of the lens; in almost all cases the lens axis passes through the physical centre of the lens.

Lenses are divided by the bend of these two surfaces. A lens is biconvex if both surfaces are convex; similarly, a lens with two concave surfaces is biconcave. If one of the surfaces is flat, the lens is termed Plano-convex or Plano-concave depending on the curvature of the other surface. A lens with one convex and one concave side is named convex-concave, and in this case if both curvatures are equal it is a meniscus lens. If the lens is biconvex or Plano-convex, a collimated or parallel beam of light passing along the lens axis and through the lens will be converged to a spot on the axis, at a certain distance behind the lens. In this case, the lens is called a constructive or converging lens.

If the lens is biconcave or Plano-concave, a collimated beam of light passing through the lens is diverged; the lens is thus called a negative or diverging lens. The beam after passing through the lens appears to be emanating from a particular point on the axis in front of the lens; the detachment from this point to the lens is also known as the focal length, although it is negative with respect to the focal length of a converging lens.
If the lens is convex-concave, whether it is converging or diverging depends on the relative curvatures of the two surfaces. If the curvatures are equal, then the beam is neither converged nor diverged.

Music

Music is an art form that involves organized sounds and quiet. It is articulated in terms of pitch (which includes melody and harmony), rhythm (which includes tempo and meter), and the quality of sound (which includes timbre, articulation, dynamics, and texture).
Music may also absorb generative forms in time through the construction of patterns and combinations of natural stimuli principally sound. Music may be used for artistic or aesthetic, communicative, entertainment, traditional or religious purposes. The definition of what constitutes music varies according to culture and social context, with assorted interpretations of the term being established under sub-genres of the art. Within "the arts", music can be classified as a performing art, a fine art, or an auditory art form

The history of music predates the written word and is tied to the enlargement of each unique human culture. The development of music among humans occurred against the backdrop of natural sounds such as birdsong and the sounds other animals use to communicate. primeval music, once more commonly called primitive music, is the name given to all music created in preliterate cultures (prehistory), beginning somewhere in very late geological history.

Artificial intelligence (Intelligence, IQ, and g)

Intelligence, IQ, and g are unusual. Intelligence is the word used in normal discourse to refer to cognitive capability. However, it is generally regarded as too vague to be useful for a scientific treatment of the subject. The intelligence quotient is an index calculated from the scores on test items judged by experts to include the abilities enclosed by the term intelligence. IQ measures a multidimensional quantity: it is an amalgam of different kinds of abilities, the proportions of which may differ between IQ tests. The dimensionality of IQ scores can be studied by factor analysis, which reveals a single dominant factor underlying the scores on all IQ tests. This factor, which is a hypothetical construct, is called g. Variation in g corresponds closely to the innate notion of intelligence, and thus g is sometimes called general cognitive ability or common intelligence.

Electronic mixer

An elepctronic mixer is a device for addition two or more electronic signals. There are two basic types of mixer. Additive mixers add two signals together, and are used for such applications as audio mixing. Multiplying mixers multiply the signals together, and create an output containing both original signals, and new signals that have the sum and dissimilarity of the frequency of the original signals.Additive mixers are typically resistor networks, surrounded by impedance matching and amplification stages.Multiplying mixers have been done in a wide range of ways. The most popular are diode mixers, gilbert cell mixers, diode ring mixers and switching mixers.

Traffic psychology

Traffic psychology is a young escalating field in psychology. Whereas traffic psychology is first and foremost related to "the study of the behavior of road users and the psychological processes underlying that behavior" as well as to the relation between behavior and accidents, transportation psychology, sometimes referred to as mobility psychology, has its focus on mobility issues, individual and social factors in the movement of people and goods, and travel demand management.
There is no single theoretical framework in traffic psychology, but many specific models explaining, e.g., perceptual, intentional, cognitive, social, motivational and emotional determinants of mobility and traffic behavior. One of the most well-known behavioral models divides the various tasks occupied in traffic participation into three hierarchical levels, i.e. the strategic, the tactical and the operational level. The model demonstrates the diversity of decision and control tasks which have to be accomplished when driving a vehicle. However, until now, most of the psychological models have a rather heuristic nature, e.g. risk theories like the risk compensation hypothesis, Fuller's task capability model, and thus are not sufficiently precise to allow for concrete behavioral prediction and control. This is partly due to the importance of individual differences, a major topic of psychology which in traffic and transportation has not yet been adequately accounted for. On the other hand, social-psychological attitude-behavior models, such as Ajzen's theory of planned behavior, have been helpful in identifying determinants of mobility decisions.

Peafowl

The peafowl are the three variety of bird in the genera Pavo and Afropavo of the pheasant family, Phasianidae. They are most distinguished for the male's profligate tail, a result of sexual selection, which it displays as part of courtship. The male is called a peacock, the female a peahen. In common English custom, however, "peacock" is used to mean any peafowl.

Overview
The characteristic Asiatic peafowl belonging to the genus Pavo comprise the familiar Indian Peafowl, Pavo cristatus and the poorly known Dragon birds or Green Peafowl Pavo muticus. Some biologists believe that there are at least five characteristic and critically endangered species of Green Peafowl while others classify them into a single species with three species.

The Arakan Dragonbird Pavo spicifer was once inhabitant to Northern Western Myanmar, Southern Tibet and Assam. The Indo-Chinese or Siamese Dragon bird Pavo imperator was once native to South East Myanmar and Thailand. The Annametic Dragonbird Pavo annamensis occupied the broadleaf evergreen forests of Cambodia, Vietnam, Laos and Southern Yunnan China.

The Javanese Green Peafowl, Pavo javanensis is occupant only to the island of Java. The died out Malay or Pahang Peafowl Pavo muticus muticus was fantasy by early naturalists to least the Pliocene rules out an foreword by humans. Northern Yunnan is the home of one of the most fascinating forms of Green Peafowl. The Yunnan Dragonbird, Pavo yunnanensis is most characteristic.
