LITHOSPHERE

On the Earth, the lithosphere includes the crust and the uppermost mantle which is joined to the crust across the Mohorovičić discontinuity. The lithosphere is underlain by the asthenosphere, the weaker, hotter, and deeper part of the upper mantle. The boundary between the lithosphere and the underlying asthenosphere is defined by a difference in response to stress: the lithosphere remains rigid for long periods of geologic time, whereas the asthenosphere flows much more readily. As the conductively cooling surface layer of the Earth's convection system, the lithosphere thickens over time. It is fragmented into tectonic plates , which move independently relative to one another. This movement of lithospheric plates is described as plate tectonics. This is when plates move horizontally across the Earth's surface and the continents change their relative positions.

The concept of the lithosphere as Earth’s strong outer layer was developed by Barrell, who wrote a series of papers introducing the concept . The concept was based on the presence of significant gravity anomalies over continental crust, from which he inferred that there must exist a strong upper layer above a weaker layer which could flow . These ideas were enlarged by Daly , and have been broadly accepted by geologists and geophysicists. Although these ideas about lithosphere and asthenosphere were developed long before plate tectonic theory was articulated in the 1960s, the concepts that strong lithosphere exists and that this rests on weak asthenosphere are essential to that theory.

hair piece

A toupée is a hairpiece or partial wig of natural or synthetic hair worn to cover partial baldness. While toupées and hairpieces are mostly associated with male users, some women also wear hairpieces to lengthen existing hair, or cover partially exposed scalp. The desire to wear hairpieces is a response to a long-standing cultural stand against balding that crosses cultures, since times immemorial.,i.e.atleast 3100 B.C. Toupee use is the utmost and has become widespread in western as well as eastern cultures. Beacuse it is a very suitable method for dealing with baldness, and to greater cultural acceptance of the condition.

While most toupées are small and designed to cover bald spots at the top and back of the head, large toupées are not unknown, particularly among television personalities.

Toupées are also called "hairpieces", "hair patches", or "hair systems" by those seeking to avoid the negative connotations that the word "toupée" conjures up. Many women now wear hairpieces rather than full wigs if their hair loss is confined to the top and crown of their heads.

It is a charming fact that many a men often knows they are not fooling any one with the use of the toupée, but that the bias in Western culture against baldness is so strong that they feel the need to have hair on their heads. Wearing toupee is safer when compared to having been hair transplanted.

HYPNOSIS

Hypnosis is a common practice among psychology doctors in identifying their patient's disease. Often thought to be "a trance-like state that resembles sleep but is induced by a person whose suggestions are readily accepted by the subject."

The technique is sometimes used for medical purposes to relieve anxiety, or otherwise improve or alter behaviour. Its effectiveness has been clinically demonstrated in many areas, most notably in the area of acute pain relief. It is also used in popular stage acts in which subjects are persuaded to perform bizarre feats.

Other variations include so-called "mass-hypnosis," in which crowds are simultaneously influenced, and autosuggestion in which subjects persuade themselves. However, these phenomena are unlike those typically associated with the classical phenomena of hypnosis.

DYSLEXIA

Dyslexia is one of the rare diseases which is considered to be a learning disability. It manifests primarily as a difficulty with written language, particularly with reading and spelling.Though it is quiet difficult to cure, it is separate and distinct from reading difficulties resulting from other causes, such as a non-neurological deficiency with vision or hearing, or from poor or inadequate reading instruction.Evidence also suggests that dyslexia results from differences in how the brain processes written and/or spoken language. Although dyslexia is the result of a neurological difference, it is not an intellectual disability. Dyslexia occurs at all levels of intelligence.

OIL PULLING

Oil pulling or oil swishing, in alternative medicine, is a traditional Indian folk remedy that involves swishing oil in the mouth for claimed oral and systemic health benefits. It is mentioned in the Ayurvedic text Charaka Samhita where it is called Kavala Gandoosha / Kavala Graha. No scientific evidence shows anything being forced/pulled from the body by "oil pulling".

The practitioner rinses their mouth with approximately one tablespoon of oil for 15−20 minutes on an empty stomach , then spits it out. This procedure is typically performed daily.The oil is put in the mouth, with chin tilted up, and slowly swished, sucked, chomped and pulled through the teeth. The oil changes from yellow and oily consistency to a thin, white foam before spitting out. The mouth is rinsed out well after the procedure and followed by 2 - 3 glasses of water.

ARTIFICIAL INTELLIGENCE

Artificial intelligence (AI) is both the intelligence of machines and the branch of computer science which aims to create it.

Major AI textbooks define artificial intelligence as "the study and design of intelligent agents," where an intelligent agent is a system that perceives its environment and takes actions which maximize its chances of success. John McCarthy, who coined the term in 1956, defines it as "the science and engineering of making intelligent machines."

Among the traits that researchers hope machines will exhibit are reasoning, knowledge, planning, learning, communication, perception and the ability to move and manipulate objects. General intelligence has not yet been achieved and is a long-term goal of some AI research.

AI research uses tools and insights from many fields, including computer science, psychology, philosophy, neuroscience, cognitive science, linguistics, ontology, operations research, economics, control theory, probability, optimization and logic.AI research also overlaps with tasks such as robotics, control systems, scheduling, data mining, logistics, speech recognition, facial recognition and many others.

IPHONE


The most awited genre is on its move with the introduction of the iphones .The iPhone is an Internet-enabled multimedia mobile phone designed and marketed by Apple Inc. It has a multi-touch screen with virtual keyboard and buttons, but a minimal amount of hardware input. The iPhone's functions include those of a camera phone and portable media player in addition to text messaging and visual voicemail. It also offers Internet services including e-mail, web browsing, and local Wi-Fi connectivity. The first generation phone hardware was quad-band GSM with EDGE; the second generation also adds UMTS and HSDPA.

Apple announced the iPhone on 9 January . The announcement was preceded by rumors and speculations that circulated for several months. The iPhone was initially introduced in the United States on 29 June 2007 and is in the process of being introduced worldwide. It was named Time magazine's Invention of the Year in 2007. On 11 July 2008, the iPhone 3G was released and supported faster 3G data speeds and Assisted GPS.

MILK

Milk is an opaque white liquid produced by the mammary glands of female mammals . It provides the primary source of nutrition for newborn mammals before they are able to digest other types of food. The early lactation milk is known as colostrum, and carries the mother's antibodies to the baby. It can reduce the risk of many diseases in the baby. The exact components of raw milk varies by species, but it contains significant amounts of saturated fat, protein and calcium as well as vitamin C.

BODY BUILDING


Bodybuilding is the process of maximizing muscle hypertrophy through the combination of weight training, sufficient caloric intake, and rest. Someone who engages in this activity is referred to as a bodybuilder. As a sport, called competitive bodybuilding, bodybuilders display their physiques to a panel of judges, who assign points based on their aesthetic appearance. The muscles are revealed through a combination of fat loss, oils, and tanning which combined with lighting make the definition of the muscle group more distinct. Famous bodybuilders include Arnold Schwarzenegger, Kevin Levrone, Dorian Yates, Lee Haney, Lou Ferrigno, Franco Columbu, Ronnie Coleman, and Jay Cutler.
