Single (cricket) run down

Posted on February 25th, 2008 in Uncategorized by admin

In the sport of cricket, a single is scored when the batsman take one run, either following a successful shot (with the run attributed to the on-strike batsman) or when running for a bye or leg bye (counted as an extra).

Unlike when a boundary is hit (and the run are scored even if the batsmen don’t leave their creases), scoring a single requires the batsmen to physically run between the wickets. This introduces the risk of being run out, so effective communication between the batsmen is vital. If one batsman attempts to run and the other stays put, then a humiliating run out is likely, but quick and well attuned batsmen may be able to run “quick singles” when other batsmen wouldn’t. In general, singles are much easier to score when the field is set further out, but bringing more fielders in makes it easier for the on-strike batsman to hit boundaries.

Singles usually rotate the strike in a partnership, but because the bowling end changes at the end of an over, singles deliberately only taken at the end of an over are used by quality batsmen to keep the strike when they are batting with the tail-enders, who are unlikely to survive for long against quality bowling and whom an experienced batsman will normally try to protect.

Laminar flow cabinet standard equipment for

Posted on February 24th, 2008 in Uncategorized by admin

A Laminar flow cabinet or laminar flow closet is a carefully enclosed bench designed to prevent contamination of semiconductor wafers, biological samples, or any particle sensitive device. Air is drawn through a HEPA filter and blown in a very smooth, laminar flow towards the user. The cabinet is usually made of stainless steel with no gaps or joints where spores might collect.

Such hoods exist in both horizontal and vertical configurations, and there are many different types of cabinets when it comes to Airflow patterns and acceptable uses of these cabinets. NSF49 is the commonly accepted regulatory standard for these cabinets.

Laminar flow cabinets may have a UV-C germicidal lamp to sterilize the shell and contents when not in use. (It is important to switch this light off as it will quickly give any exposed skin sunburn, and may cause cataracts)

Degree of start-stop distortion start

Posted on February 24th, 2008 in Uncategorized by admin

In telecommunication, the term degree of start-stop distortion has the following meanings:

  1. In asynchronous data transmission, the ratio of (a) the absolute value of the maximum measured difference between the actual and theoretical intervals separating any significant instant of modulation (or demodulation) from the significant instant of the start element immediately preceding it to (b) the unit interval.
  2. The highest absolute value of individual distortion affecting the significant instants of a start-stop modulation.

The degree of distortion of a start-stop modulation (or demodulation) is usually expressed as a percentage. Distinction can be made between the degree of late (positive) distortion and the degree of early (negative) distortion.

BMW S85 utilize

Posted on February 23rd, 2008 in Uncategorized by admin

The BMW S85B50 is a DOHC 40-valve V10 automotive piston engine found on the E60 M5 and E63 M6. It was inspired by BMW’s formula 1 racing division and shares many components and technology that powered the BMW Williams F1 cars.


Technology & Performance

The S85B50 is a high-revving engine designed to utilize power from a wide rev band. Having a redline of 8250 rpm, it achieves over 100bhp/liter and features a very high compression ratio of 12.0:1, beating the previous M3 of 11.5:1

  • 5.0 Liter V10 engine, 507 hp/520Nm, 383 ft·lbf torque
  • Double VANOS system which varies both intake and exhaust valve timing
  • 10 individual electronically controlled throttles
  • Knock sensors have been eliminated to utilize the new “ionic current” measuring system. Using the ionic current system, engine misfires as well as knock can be measured simultaneously. Combustion quality raises or lowers cylinder pressure. The ionic current is measured by passing a low voltage between the spark plugs immediately following the ignition spark.
  • Dry sump lubricating system


Awards

In 2005, the first year that it was nominated, the S85B50 won four different International Engine of the Year awards in the following 4 categories:

  1. International Engine of the Year, BMW 5.0 Liter V10 (M5,M6)
  2. Best Performance Engine
  3. Best New Engine
  4. Best Above 4.0 Liter

In 2006 the S85B50 again won several International Engine of the Year awards, winning in the following 3 categories:

  1. International Engine of the Year, BMW 5.0 Liter V10 (M5,M6)
  2. Best Performance Engine
  3. Best Above 4.0 Liter

In 2007 the S85B50 again won several International Engine of the Year awards, winning in the following 2 categories:

  1. Best Performance Engine
  2. Best Above 4.0 Liter

Punt kick Kick

Posted on February 23rd, 2008 in Uncategorized by admin

The Punt kick is one of, if not the most common style of kicking in football games. It is described as kicking the ball without the ball first hitting the ground. It is practised in many sports to some degree: Australian rules football, American & Canadian football, rugby league, and rugby union.

Australian rules football uses the kick more than any other code of football. This has led to Australian rules players to play for other football codes, particularly to become American football specialist punters (See Players who have converted from one football code to another).


Execution

To punt accurately and well, players need to have good balance and timing. First, the kicker points the ball in the direction in which he wants the kick to go. The ball is held at waist height and at arm’s length away from the body. The ball is held at a 45° angle to the axis of the foot.

To kick with the right foot, the ball is held underneath with the right hand close to the body and the left hand farthest away at the top and the side of the ball. For a left-footed kick, hands are exchanged, right hand below the left. The hands create a channel through which to kick the ball. With the ball at waist height, the ball is released and guided down with the hand of the opposite side of the kicking foot. Contact is made in the centre of the ball, with the toes pointed down, just above the boot laces with the ankle extended and the hard upper bridge of the foot to impart full power.

Kicking on the run gives less control over the football; players are taught to slow down and steady themselves prior to kicking. The kick concludes with a high follow-through, with the foot above head height. The kicking leg should remain straight, and the toes pointed.

In flight, a punted football remains flat, i.e. with the longer axis roughly parallel to the ground. It does not rotate end-over-end as a drop punt would. However, a poorly executed punt kick, known in Australian rules football as a helicopter punt (or sometimes mongrel punt) may gyrate flatly in the air, reminiscent of the rotor of a helicopter.

Starting fluid starting an

Posted on February 22nd, 2008 in Uncategorized by admin

Starting fluid is a mixture of diethyl ether, volatile hydrocarbons (heptane, butane and propane), dimethyl ether (as a propellant), and carbon dioxide. It is often useful when starting direct injected diesel engines or lean burn spark engines running on alcohol fuel. Starting fluid works due to the low autoignition temperature of diethyl ether: 360°F (182°C).

Starting fluid comes in a regular or premium grade. The regular grade contains 21-35% diethyl ether. Premium grade starting fluids have a 40-60% diethyl ether content. The rest of the volume is commonly taken by heptane.

Using starting fluid to get the engine running faster avoids wear, especially on rarely used engines. Mechanics, especially amateur mechanics that lack diagnostic machines, sometimes use it to diagnose starting problems. If sprayed into the air intake on a car, it can be used to determine whether the spark and ignition system of the car is functioning, since the engine will run until the starting fluid vapors in the intake system are exhausted. It is used more often with carbureted engines than with fuel injection systems. It is especially useful for starting diesel engines in colder weather as they do not run efficiently until the engine block warms up to a certain degree.

Starter fluid is sometimes used as an inhalant. The majority of the effects are caused by diethyl ether in liquid form rather than as vapor.

Krajina dinar start

Posted on February 22nd, 2008 in Uncategorized by admin

The dinar was the currency in Republic of Serbian Krajina between 1992 and 1994. There were three distinct dinara. The first was introduced in July 1992 in parallel with the new Yugoslav dinar of that year, to which it was equal. The second dinar replaced the first at a rate of 1 million to one on October 1, 1993, whilst the third replaced the second at a rate of 1 billion (109) to one on January 1, 1994. In 1995, Croatia took control of the region and the Croatian kuna became the currency.
