IEEE Medal of Honor

The IEEE Medal of Honor is the highest recognition of the Institute of Electrical and Electronics Engineers (IEEE). It has been awarded since 1917, when its first recipient was Major Edwin H. Armstrong. It is given for an exceptional contribution or an extraordinary career in the IEEE fields of interest. The award consists of a gold medal, bronze replica, certificate and honorarium.

The medal was originally founded by the Institute of Radio Engineers (IRE) as the IRE Medal of Honor. It became the IEEE Medal of Honor when IRE merged with the American Institute of Electrical Engineers (AIEE) to form IEEE in 1963.

American Institute of Electrical Engineers

The American Institute of Electrical Engineers was a United States based organization of electrical engineers that existed between 1884 and 1963 (when it merged with the Institute of Radio Engineers (IRE)). The 1884 founders of the American Institute of Electrical Engineers (AIEE) included some of the most prominent inventors and innovators in the then new field of electrical engineering, among them Thomas Alva Edison, Elihu Thomson, Edwin J. Houston, and Edward Weston.

The purpose of the AIEE was stated "to promote the Arts and Sciences connected with the production and utilization of electricity and the welfare of those employed in these Industries: by means of social intercourse, the reading and discussion of professional papers and the circulation by means of publication among members and associates of information thus obtained." The first president of AIEE was Norvin Green, president of the Western Union Telegraph Company. Other notable AIEE presidents were Alexander Graham Bell (1891-1892), Charles Proteus Steinmetz (1901-1902), Schuyler S. Wheeler (1905-1906), Dugald C. Jackson (1910-1911), Michael I. Pupin (1925-1926), and Titus G. LeClair (1950-1951).

Phenethylamine

Phenethylamine, or β-phenyl ethylamine or 2-phenylethylamine, is an alkaloid and monoamine. Phenethylamine also has a constitutional isomer α-phenylethylamine (1-phenylethylamine), which has two stereoisomers: (R)-(+)-1-phenylethylamine and (S)-(-)-1-phenylethylamine. In the human brain, 2-phenethylamine is believed to function as a neuromodulator or neurotransmitter (trace amine). Phenethylamine is a natural compound biosynthesized from the amino acid phenylalanine by enzymatic decarboxylation. It is also found in many foods such as chocolate, especially after microbial fermentation. However trace amounts from food are quickly metabolized by the enzyme MAO-B, preventing significant concentrations from reaching the brain.
Phenylethylamine is a precursor to the neurotransmitter phenylethanolamine.

D-Phenylalanine increases the brain content of phenylethylamine .Phenylethylamine has been shown at least indirectly to satisfy the four main criteria required to demonstrate that a neuroamine sustains mood and that its deficit can be responsible for depression.Antidepressant drug therapy is an indirect (pharmacological) "replacement" of brain phenylethylamine .Substituted phenethylamines are a broad and diverse class of compounds that include stimulants, hallucinogens, entactogens, anorectics, bronchodilators, and antidepressants.

MRI Scans

Magnetic resonance imaging (MRI) uses a large magnet and radio waves to look at organs and structures inside your body. Health care professionals use MRI scans to diagnose a variety of conditions, from torn ligaments to tumors. MRIs are very useful for examining the brain and spinal cord.

During the scan, you lie on a table that slides inside a tunnel-shaped machine. Doing the scan can take a long time, and you must stay still. The scan is painless. The MRI machine makes a lot of noise. The technician may offer you earplugs.

Before you get a scan, tell your doctor if you

* Are pregnant
* Have pieces of metal in your body. You might have metal in your body if you have a shrapnel or bullet injury or if you are a welder
* Have electronic devices in your body, such as a cardiac pacemaker

Transmission

In telecommunications, transmission is the process of sending, propagating and receiving an analogue or digital information signal over a physical point-to-point or point-to-multipoint transmission medium, either wired or wireless. Tranmission technologies and schemes typically refer to physical layer protocol duties such as modulation, demodulation, line coding, equalization, error control, bit synchronization and multiplexing, but the term may also involve higher-layer protocol duties, for example digitalization of an analog message signal, and source coding (compression).

Transmission of a digital message, or of a digitized analog signal, is known as data transmission or digital communication.

Electric vehicles in 1959

In 1959 the Henney Kilowatt was introduced and was the world's initial modern transistor-regulated electric car and the predecessor to the more recent battery electric vehicles such as General Motors EV1. Only 47 Henney Kilowatts were created, 24 being sold as 1959 models and 8 as 1960 models. It is not clear what happened to the other 15 built but it could be probable that they were sold as 1961 or 1962 models. None of the 8 1960 models were sold in the direction of the public because of the high manufacturing costs, but were sold to the electric cooperatives who funded the project.

It is estimated that there are connecting four and eight Henney Kilowatt battery electric vehicles still in existence with at least two of the survivors still driven at times.

Battery electric vehicles had issues with high battery costs, with restricted travel distances, with charging time and the lifespan of the battery, although advancements in battery technology has addressed a lot of those problems.

Love :Comparison of scientific views

Biological models of love tend to see it as a mammalian drive, similar to appetite or thirst. Psychology sees love as more of a social and cultural occurrence. There are probably elements of fact in both views certainly love is intolerant by hormones, neurotrophins , and pheromones, and how populace think and behave in love is prejudiced by their conceptions of love. The conservative view in biology is that there are two main drives in love sexual attraction and add-on. Attachment between adults is supposed to work on the same main beliefs that lead an infant to become attached to its mother. The conventional mental view sees love as being a combination of companionate love and fervent love. Passionate love is intense longing, and is often accompany by physiological arousal. Companionate love is love and a feeling of familiarity not accompanied by physiological stimulation.

Studies have shown that brain scans of those obsessed by love display a similarity to those with a mental illness. Love creates action in the same area of the brain that hunger, thirst, and drug cravings make activity in. New love, therefore, could possibly be more physical than moving. Over time, this response to love mellows, and dissimilar areas of the brain are activated, primarily ones connecting long-term commitments. Dr. Andrew Newberg, a neuroscientist, suggests that this response to love is so similar to that of drugs since without love, humanity would die out.

Psychology View of Love

Psychology depicts love as a cognitive and social occurrence. Psychologist Robert Sternberg formulate a triangular theory of love and argued that love has three different mechanism: intimacy, commitment, and passion. Intimacy is a form in which two people share confidence and various particulars of their personal lives. Intimacy is usually shown in friendships and dreamy love affairs. Commitment, on the other hand, is the expectation that the association is permanent. The last and most common form of love is sexual magnetism and passion. Passionate love is shown in obsession as well as romantic love. All forms of love are viewed as varying combination of these three mechanism.

Following development in electrical theories, such as Coulomb's law, which showed that positive and negative charges attract, analogs in human life were urbanized, such as "opposites attract". Over the last century, research on the nature of human mate has generally found this not to be true when it comes to character and character; people tend to like people similar to themselves. However, in a few strange and specific domains, such as immune systems, it seems that human prefer others who are unlike themselves, since this will lead to a baby which has the finest of both worlds. In fresh years, various human bonding theories have been residential described in terms of attachment, ties, bonds, and affinity.

Scientific views of Love : Chemistry

Biological models of sex tend to view love as a mammalian force, much like hunger or thirst. Helen Fisher, a foremost expert in the topic of love, divides the knowledge of love into three partly-overlapping stages: lust, attraction, and accessory. Lust exposes people to others, romantic magnetism encourages people to focus their energy on mate, and accessory involves tolerating the spouse long sufficient to rear a child into infancy.

Lust is the initial passionate sexual desire that promote mating, and involves the increased release of chemicals such as testosterone and estrogen. These properties rarely last more than a few weeks or months. Attraction is the more individualized and romantic desire for a specific candidate for mating, which develops out of lust as commitment to an individual mate forms. Recent studies in neuroscience have indicate that as people fall in love, the brain consistently release a certain set of chemicals, counting pheromones, dopamine, norepinephrine, and serotonin, which act related to amphetamines, stimulating the brain's pleasure center and foremost to side-effects such as an augmented heart rate, loss of appetite and sleep, and an intense feeling of enthusiasm. Research has indicated that this stage usually lasts from one and a half to three years.

Scientific views

Throughout record, philosophy and religion have done the most assumption on the phenomenon of love. In the last century, the science of psychology has written a great contract on the subject. In new years, the sciences of evolutionary psychology, evolutionary biology, anthropology, neuroscience, and biology have added to the considerate of the nature and meaning of love.

Interpersonal love

Interpersonal love refers to love among human beings. It is a more potent feeling than a simple liking for another. Unrequited love refers to that approach of love which is not joint. Interpersonal love is most closely linked with interpersonal relationships. Such love might exist among family members, friends, and couples. There are also a amount of psychological disorders associated to love, such as erotomania.

Love

Love represents a range of emotions and experience associated to the senses of affection with sexual attraction. The word love can refer to a range of different feelings, states, and attitudes, ranging from general pleasure to deep interpersonal attraction. This diversity of meanings, joint with the difficulty of the approach involved, makes love abnormally difficult to constantly define, even compare to other affecting states.

As a conceptual concept love regularly refers to a strong, ineffable sensation towards another person. Even this limited start of love, however, encompasses a wealth of diverse feelings, from the fervent desire and confidence of romantic love to the nonsexual. Love in it’s a variety of forms acts as a major launch pad of interpersonal relationships and, owing to its central psychological significance, is one of the most common themes in the original arts.

Biotechnology

Biological technology is technology based on biology, particularly when used in agriculture, food science, and medicine. Biotechnology means any technological application that uses biological systems, living organisms, or derivatives thereof, to construct or change products or processes for specific use.

Biotechnology combines disciplines like genetics, molecular biology, biochemistry, embryology and cell biology, which are in turn allied to practical disciplines like chemical engineering, information technology, and robotics.Biotechnology can also be defined as the exploitation of organisms to do practical things and to provide useful products.

One characteristic of biotechnology is the directed use of organisms for the manufacture of organic products (examples include beer and milk products). For another example, naturally present bacteria are utilized by the mining industry in bioleaching. Biotechnology is also used to recycle, treat waste, clean up sites infected by industrial activities (bioremediation), and produce biological weapons.
