Harrison’s Principles of Internal Medicine internal

Posted on December 23rd, 2007 in Uncategorized by admin

Harrison’s Principles of Internal Medicine is an American textbook of internal medicine. First published in 1950, it is presently in its sixteenth edition. Although it is aimed at all members of the medical profession, it is mainly used by internists and junior doctors in this field, as well as medical students.

The work is named after Dr Tinsley R. Harrison of Talladega, Alabama, who served as editor-in-chief of the first five editions and established the format of the work - a strong basis of clinical medicine interwoven with an understanding of pathophysiology.

Tribsa motorcycle

Posted on December 22nd, 2007 in Uncategorized by admin

The Tribsa was a modified Cafe racer motorcycle of the 1960s-1970s, the name coming from a contraction of Triumph and BSA (the Birmingham Small Arms Company) - the two brands of motorcycle combined.

The intention was to combine the best elements of each to give a superior bike to either. The usual practice was to take the Triumph parallel twin engine and use it to replace the engine on a B series BSA motorcycle which were generally single cylinder.
The Triumph engine gave good performance and reliability and could be tuned easily for greater power.

The Tribsa was an alternative to the Triton which was a Triumph engine in a Norton “featherbed” frame.

Dummy (football) countries also utilize kick

Posted on December 22nd, 2007 in Uncategorized by admin

A dummy or feint is a football (soccer) and rugby term used to refer to a particular player deceiving the opposition into believing he is going to pass, shoot or receive the ball and instead doing something entirely different, thus gaining an advantage.


Uses

In football (soccer), a dummy is used most often in offensive free kick situations. A player will run to the ball and look as if to strike the ball, but instead leave it (or touch it slightly) for another player to shoot. The next most common instance is also an offensive situation, in which a player, in a reasonable shooting area, fakes a shot to trick a defender coming in for a tackle and have him flinch away. This allows the player to go around the defender and shoot from a closer distance. This dummy can also be used on a goalkeeper in a one-on-one situation.

In rugby football, a dummy has a similar meaning, but is generally confined to a player leading their opposing players into believing that they are about to pass or kick the ball, but instead retaining and running with the ball. This has the effect of drawing defending players to the apparent recipient of the ‘dummy pass’ or likely target area of the ‘dummy kick’.

Saab two-stroke equipment for engine

Posted on December 21st, 2007 in Uncategorized by admin

The first Saab two-stroke engine was based on a DKW design. The SAAB engine, a two cylinder with 764 cm3 engine displacement and 25 hp was transversally placed in the 1950 - 1956 Saab 92, giving it a top speed of 100 km/h. With the 1954 model engine output was raised to 28 hp. It had some features only found in modern cars such as one ignition coil per cylinder.

The second type of SAAB two stroke engine was a longitudinally placed 3 cylinder of 748 cc and initially 33 hp. This engine was used in the Saabs 93, 94 (with an engine tuned to 57,5 hp), Saab Sonett I and II, 95, 96, Saab GT750, the Saab Formula Junior and the Saab Quantum.

The 1958-59 Sports version of the 93B had 48-50 hp in base version and 57 hp in super version. This model had triple carburetors.

From 1959 displacement was raised to 841 cc with 38 hp. For model year 1966, the ’standard’ 3-cylinder two-stroke engine was fitted with triple carburetors. From model year 1967 it was replaced with the Ford Taunus V4 engine.

SAAB also made some experimental V6 engines, by mounting two three cylinder two-stroke engines together, at an angle. One had carburetors on the outside, while another was more conventional, with a carburetor in between the two blocks.

Australian work boots boots

Posted on December 21st, 2007 in Uncategorized by admin

Australian work boots (or generically elastic-sided boots) are a unique style of work shoe, typically constructed with a leather upper bound together with elastic sides and pull tabs on the front and back of the boot. The shoe lacks a tongue, and laces, and often contains a steel toe cap for occupational health and safety reasons. When the shoe contains a steel cap they are often known as “safety boots” or “steel toe boots”. The boots generally lack an inner lining. The sole is generally polyurethane and the leather uppers are treated to be resistant to hot water, fats and mild alkaline and acid solutions.

The elasticated side design allows the wearer to easily slip their boots on and off without the hassle of laces, but with the firm fit of lace-up boots. There are several Australian companies manufacturing boots in this classic style today. Some of the more popular brands are Blundstone (perhaps the original dating back to 1870), Rossi Boots and R. M. Williams. In Australian English, the manufacturer’s brand name is often associated generically with this style of boot, leading to the names Blundstones or Blunnies, RMs or Redbacks.

The shoes are typically worn as safety boots in occupationally hazardous environments, as ordinary work boots for people whose work is occasionally hazardous and who need to enter hazardous sites, as formal dress boots, as riding boots, or for particular aesthetic purposes. In the last category, the Novocastrian dance ensemble Tap Dogs uses modified work boots as tap shoes.

AntiCMOS boot

Posted on December 21st, 2007 in Uncategorized by admin

AntiCMOS is a boot virus. Its first discovery was at Lenart, Slovenia, which led to its alias of Lenart. It was isolated in Hong Kong several times at the beginning of 1994, but did not become common until it spread to North America in the Spring of 1995. AntiCMOS is a fairly standard boot virus, and is primarily notable for being one of the few DOS viruses to remain in the wild as of 2005.

AntiCMOS is so named because it has the intended effect of erasing all CMOS information. This does not occur because of a bug in the virus code. This is true of all AntiCMOS variants that have appeared in the wild. The payload date of December 1993 and the obsolete nature of these variants makes it very unlikely that AntiCMOS’s payload will ever be a threat.

Potential gradient electric starters

Posted on December 21st, 2007 in Uncategorized by admin

A potential gradient is the local space rate of change of the potential.

In electrostatics then, it is the local space rate of change of the electric potential:

<math>\mathbf{E} = - \delta V / \delta s</math>[1]

Units are volts per meter (V/m). The electric field is the same as the potential gradient but with opposite sign.

In biology, the net difference in electric charge across a cell membrane.
