Genetics

Genetics is the science of heredity and variation in living organisms.Knowledge that desired characteristics were present at birth has been implicitly used since prehistoric times for improving crop plants and animals through selective breeding. However, the modern science of genetics, which seeks to understand the mechanisms of inheritance, only began with the work of Gregor Mendel in the mid-1800s.

Mendel observed that inheritance is basically a discrete process with specific traits that are inherited in an independant manner. These basic units of inheritance is now known as "genes". In the cells of organisms, genes exist actually in the structure of the molecule DNA and the information genes contain is used to create and control the components of cells. Although genetics plays a large role in determining the appearance and behavior of organisms, it is the interaction of genetics with the environment an organism experiences that determines the ultimate outcome. For example, while genes play a role in determining a person's height, the nutrition and health that person experiences in childhood also have a large effect.

Mental health

Mental health is a idea that refers to a human individual's emotional and psychological well-being. Merriam-Webster defines mental health as "A state of emotional and psychological well-being in which an individual is able to use his or her cognitive and emotional capabilities, function in society, and meet the ordinary demands of everyday life."

According to the World Health Organization (WHO), there is no one "official" definition of mental health. Cultural differences, subjective assessments, and competing professional theories all affect how "mental health" is defined. In general, most experts agree that "mental health" and "mental illness" are not opposites. In other words, the absence of a recognized mental disorder is not of necessity an indicator of mental health.
One way to think about mental health is by looking at how efficiently and successfully a person functions. Feeling capable and competent; being able to handle normal levels of stress, preserve satisfying relationships, and lead an independent life; and being able to "bounce back," or recover from difficult situations, are all signs of mental health.
Encompassing your emotional, social, and—most importantly—your mental well-being; All these aspects—emotional, physical, and social—must function jointly to achieve overall health.

Refrigerator

A typical refrigerator with its door open refrigerator is a cooling machine comprising a thermally insulated compartment and a mechanism to transfer heat from it to the outside environment, cooling the contents to a temperature below ambient. Refrigerators are widely used to store foods which deteriorate at ambient temperatures; spoilage due to bacterial growth and other processes is much slower at low temperatures. Devices described as "refrigerators" maintain a temperature a few degrees above the freezing point of water; similar devices which maintain temperatures below the freezing point of water are called "freezers". The refrigerator is a relatively modern creation amongst kitchen appliances. It replaced the common icebox which had been a household item for almost a century and a half prior, and is sometimes still called by the original name "icebox".

Superscalar

A superscalar CPU architecture implements a form of parallelism called Instruction-level parallelism within a solitary processor. It thereby allows faster CPU throughput than would otherwise be possible at the same clock rate. A superscalar architecture executes more than one instruction during a single pipeline stage by pre-fetching several instructions and at the same time dispatching them to redundant functional units on the processor.

History

Seymour Cray's CDC 6600 from 1965 is often mentioned as the first superscalar plan. The Intel i960CA and the AMD 29000-series 29050 microprocessors were the first commercial single-chip superscalar microprocessors. RISC CPUs like these brought the superscalar idea to micro computers because the RISC design results in a simple core, allowing straightforward instruction send off and the inclusion of multiple functional units on a single CPU in the inhibited design rules of the time. This was the reason that RISC designs were faster than CISC designs through the 1980s and into the 1990s.

Key

A key is a device which is used to open a lock. It typically consists of a specially-shaped piece of flat metal, with cut notches (forming teeth), and/or milled grooves which fit the shape of the lock and can open the properly combinated lock by (usually) being turned in the lock housing. This portion of the key is referred to as the blade. The wider grip, referred to as the bow, is establish at the top of the key to facilitate turning. regularly, there are only a small number of keys which can work a certain lock. In some residential locks, all of the keys for a lock are given to the purchaser of the lock. Duplicates of the key can usually be made by anyone with the correct key blank and key machine. Some manufacturers assign an identification number to each lock and key combination. Knowing the identification number of such a lock allows a duplicate key to be made at certain places. Many residential keys are recognized by the key cuts stamped on the key bow.
Most people in modern society use keys on a daily basis, to secure their home, their vehicle, or to access their workplace, among other uses. Those that use a number of keys will typically place them on a ring or key chain, often with other items such as key fobs.

Ancient Tamil gods and goddesses

The religion of the ancient Tamils directly followed Hinduism.although persisting with its roots of nature worship. The most popular deity was Murugan, who has from a very early date been recognized with Karthikeya, the son of Siva. Muruga might have been a different deity at first stemming from a local deity. According to the noted expert on Tamil culture Kamil V. Zvelebil, "Subrahmanya-Murugan is one of the most complicated and baffling deities for analysis". The worship of Amman or Mariamman, consideration to have been derived from Kotravai, an ancient mother goddess, also was very common. Kannagi, the heroine of the Cilappatikaram, was worshipped as Pathini by many Tamils, particularly in Sri Lanka. There were also many temples and devotees of Thirumaal, Siva, Ganapathi, and the other common Hindu deities.

Traffic calming

Traffic reassuring is a set of strategies used by urban planners and traffic engineers which aims to slow down traffic and improve safety for pedestrians and bicyclists, although some of these features can also be dangerous to cyclists. It is now relatively common in Europe, especially Northern Europe; less so in North America.
Traffic calming has traditionally been justified on the grounds of pedestrian security and reduction of noise and local air pollution which are side effects of the traffic. However, it has become increasingly apparent that streets have many social and recreational functions which are severely impaired by fast car traffic. For example, residents of streets with light traffic had, on average, three more friends and twice as many acquaintances as the people on streets with heavy traffic which were otherwise similar in dimensions, income, etc. For much of the twentieth century, streets were designed by engineers who were charged only with ensuring traffic flow and not with fostering the other functions of streets. The rationale for traffic calming is now broadening to include designing for these functions.
Displaced traffic is not fully pushed onto other routes, as some travelers may begin to walk or use other modes such as public transit and bicycles to get where they are going. Still, in most cases the affected motorists have few alternatives aside from either navigating the newly erected obstacles or finding a more palatable route. This happens because high traffic tends to be generated by motorists passing through the area and not by the local residents.

It should be noted the some of these measures have a tendency to irritate and annoy drivers rather than calm them and others can actually increase traffic throughput. Some drivers who slow down at calming points, however, accelerate and speed after passing them in order to "catch up for lost time". For this reason, more advanced methods integrated into the design of the street, which make slower speeds seem more natural to drivers and less of an artificial imposition, are now preferred - the goal is to slow down the driver through psychological, at least partly subconscious means instead of simply forcing him to do so.

One major side effect of traffic reassuring is the impedance to emergency services. A police car can easily navigate most traffic reassuring measures. The same cannot be said for fire trucks and ambulances, however. They often have to slow down to safely cross speed bumps or chicanes. In some locales, the law prohibits traffic calming measures along the routes used by the urgent situation services.
There are 3 "E"'s that traffic engineers refer to when discussing traffic reassuring: engineering, education, and enforcement. Because neighborhood traffic management studies have shown that often it is the residents themselves that are largely contributing to the perceived speeding problem within the neighborhood, it is strained that the most effective traffic calming plans will entail all three components, and that engineering measures alone will not produce satisfactory results.
