Some words on Georgius Agricola

Georgius Agricola was born on March 24th  1494 at  Clauchau in  Saxony and died on November 21st 1555 at Chemnitz.

He was a  German scholar and scientist known as “the father of mineralogy.” While a highly educated classicist and humanist, well regarded by scholars of his own and later times, he was yet singularly independent of the theories of ancient authorities. He was indeed among the first to found a natural science upon observation, as opposed to speculation. His De re metallica dealt chiefly with the arts of mining and smelting; his De natura fossilium, considered the first mineralogy textbook, presented the first scientific classification of minerals (based on their physical properties) and described many new minerals, their occurrence and mutual relationships.

The digestive system and human ageing

The digestive system and human ageing: Loss of teeth, which is often seen in elderly people, is more apt to be the result of long-term neglect than a result of ageing itself. The loss of teeth and incidence of oral disease increase with age, but, as programs of water fluoridation are expanded and the incidence of tooth decay in children is reduced, subsequent generations of the elderly will undoubtedly have better teeth than the present generation.

While it is true that the secretion by the stomach of hydrochloric acid, as well as other digestive enzymes, decreases with age, the overall process of digestion is not significantly impaired in the elderly. Sugar, proteins, vitamins, and minerals are absorbed from the stomach and intestine as well in the elderly as in the young. Some investigations indicate a slight impairment in fat absorption, but the reduction is probably of little practical significance.

These findings have important implications for nutrition of the elderly. There is no evidence that the intake of any nutrient, such as vitamins and minerals, need be increased in the elderly because of impaired absorption. Nutritional deficiencies can be avoided as long as the diet is varied to assure adequate intake of all nutritional elements. Deficiencies are most likely to develop from poor eating habits, such as excessive intake of carbohydrate with a reduction in protein. In the elderly these deficiencies are most apt to be in the intake of protein, calcium, iron, vitamin A, and thiamine (also called vitamin B1).

Effect of ageing of the body systems

Diseases of the heart are the single largest cause of death after age 65. Thus, with increasing age the heart becomes more vulnerable to disease. Even in the absence of detectable disease, the heart undergoes deleterious changes with advancing age. Structural changes include a gradual loss of muscle fibres with an infiltration of fat and connective tissue. There is a gradual accumulation of insoluble granular material (lipofuscin, or “age pigment”) in cardiac muscle fibres. These granules, composed of protein and lipid (fat), make their first appearance by the age of 20 and increase gradually, so that by the age of 80 they may occupy as much as 5–10 percent of the volume of a muscle fibre.

The heart also shows a gradual reduction in performance with advancing age. The amount of blood pumped by the heart diminishes by about 50 percent between the ages of 20 and 90 years. There are marked individual differences in the effects of age. For
<pre>example, some 80-year-old individuals may have cardiac function that is as good as that of the average 40-year-old individual.</pre>
Under resting conditions, the heart rate does not change significantly with age. During each beat, however, the muscle fibres of the heart do not contract as rapidly in the old as in the young. This reduction in power, or rate of work, is due to the age-associated reduction in the activities of certain cellular enzymes that produce the energy required for muscular contraction.

In spite of these changes, the heart, in the absence of disease, is able to meet the demands placed upon it. In response to physical exercise it can increase its rate to double or triple the amount of blood pumped each minute, although the maximum possible output falls, and the reserve capacity of the heart diminishes with age.

Academy Award

The Academy Award (in full Academy Award of Merit) is the other name for Oscar and any of several awards presented annually by the Academy of Motion Picture Arts and Sciences, located in Beverly Hills, California, U.S., to recognize achievement in the film industry. The award, a gold-plated statuette, is bestowed upon winners in the following 25 categories: best picture, actor, actress, supporting actor, supporting actress, directing, original screenplay, adapted screenplay, cinematography, art direction and set decoration, editing, original musical or comedy score, original dramatic score, original song, costume design, makeup, sound, sound effects editing, visual effects, foreign-language film, animated feature film, animated short, live-action short, documentary feature, and documentary short. In a few select categories (e.g., makeup, sound editing) awards may not be given every year. The academy also presents scientific and technical awards, special achievement awards, honorary awards, the Jean Hersholt Humanitarian Award, the Irving G. Thalberg Memorial Award (for excellence in producing),and the Gordon E. Sawyer Award (for technological contributions), although these are not necessarily awarded annually.

To be eligible for an award in a given year, a film must be publicly exhibited in a 35-mm or larger-gauge format for paid admission for at least one week at a commercial theatre in the Los Angeles area between January 1 and midnight of December 31 of that year. Exceptions to this rule include foreign-language films, which are submitted by their country of origin and need not have been shown in the United States. Documentaries and short films have different eligibility requirements and are officially submitted by their producers, whereas music awards require the musical artist to file a submission form.

Only members of the Academy of Motion Picture Arts and Sciences may nominate and vote for candidates for the Oscars. The academy is divided into various branches of film production, and the nominees in each award category are chosen by the members of the corresponding branch; thus, writers nominate writers, directors nominate directors, and so forth. The entire academy membership nominates the candidates for best picture and votes to determine the winners in most of the categories.

Aside from bestowing international recognition and prestige, an Academy Award can play a crucial role in the success of the major winners. The best picture award, for example, can significantly increase the box office earnings of the winning film. For actors and directors, the award often quickly results in higher salaries and increased media attention. A long-term advantage is that award winners tend to be offered better pictures and thus receive more acclaim for that work.

When the academy was founded in 1927, the awards committee was only one of several that had been formed by the new organization. The idea of presenting awards was considered but not immediately pursued, because the academy was preoccupied with its role in labour problems, its efforts to improve the tarnished image of the film industry, and its function as a clearing-house for the exchange of ideas about production procedures and new technologies. It was not until May 1928 that the academy approved the committee’s suggestions to present Academy Awards of Merit in 12 categories—most outstanding production, most artistic or unique production, and achievement by an actor, by an actress, in dramatic directing, in comedy directing, in cinematography, in art directing, in engineering effects, in original story writing, in adaptation writing, and in title writing.

The first awards covered films that had been released between August 1, 1927, and July 31, 1928. The entire membership of the academy nominated candidates in all categories. Five boards of judges (one from each of the academy’s original branches—actors, writers, directors, producers, and technicians)then determined the 10 candidates with the most votes in each category and narrowed those 10 down to three recommendations. A central board of judges, which consisted of one member from each branch, selected the final winners.

The following year the number of categories was reduced to seven, and the two major film awards were collapsed into one, called best picture. The academy has since continued to make frequent alterations in rules, procedures, and categories. Indeed,so many changes have been made through the years that the only constant seems to be the academy’s desire to remain flexible and to keep abreast of the industry’s evolution. Among the most significant changes have been the decision in 1933 to alter the eligibility period for award consideration to the calendar year and the addition of the supporting actor and actress categories in 1936.

Originally the names of the award winners had been given to the press in advance with the stipulation that the information not be revealed until after the awards presentation. However, the Los Angeles Times printed the names of the 1939 winners in an early evening edition before the ceremony, draining the event of all its suspense during one of the industry’s biggest years. Thus, since then, the winners’ names have been a closely guarded secret until the official announcement at the awards ceremony.

The design for the award statuette—a knight standing on a reel of film and holding a sword—is credited to Metro-Goldwyn-Mayer (MGM) art director Cedric Gibbons. Sculptor George Stanley was commissioned to create the original statuette based on Gibbons’s design. For many years the statuettes were cast in bronze, with 24-karat gold plating. During World War II the statuettes were made of plaster because of metal shortages. They are now made of gold-plated britannium. The design, however, has remained unchanged, with the exception of the pedestal base, the height of which was increased in 1945. The statuette stands 13.5 inches (34.3 cm) tall and weighs 8.5 pounds (3.8 kg).

The origins of the statuette’s nickname, Oscar, have been traced to three sources. Actress Bette Davis claimed that the name derived from her observation that the backside of the statuette looked like that of her husband Harmon Oscar Nelson. Columnist Sidney Skolsky maintained that he gave the award its nickname to  negate pretension. The name has also been attributed to academy librarian Margaret Herrick, who declared that the statuette looked like her Uncle Oscar. The true origin of the nickname has never been determined.
