Record 2 2011-03-21

English

Subject field(s)
  • Nuclear Physics
CONT

Elastic collision law. An important detail which has not been discussed carefully enough in the literature is the collision law for particle–particle and particle–wall collisions in the presence of a deforming particle shape or deforming wall. The collision law that we use is an elastic one, in the following sense : linear andangular momentum are conserved, and the direction of the relative normal surface-to-surface velocityv[ cross-radial] at the point ofcontact is reversed upon collision(but the magnitude is unchanged). It is most convenient to consider binary collisions only and then just take the limit that the ‘‘mass’’ of a hard wall goes to infinity.

French

Domaine(s)
  • Physique nucléaire
OBS

On appelle «élastique» un processus dans lequel l’énergie cinétique est conservée. Par choc élastique, un neutron est néanmoins ralenti (sauf éventuellement dans le domaine thermique) car le noyau cible, pratiquement immobile initialement, encaisse un certain recul au cours du choc; nous verrons que le ralentissement élastique est surtout efficace si les collisions ont lieu sur les noyaux légers.

Subject field(s)
  • Atmospheric, Climatic and Meteorological Phenomena
CONT

The shovel shear test provides information about the location where the snow could fail in shear. It is best applied for identification of buried weak layers and does not usually produce useful results in layers close to the snow surface. Soft snow near the surface is better tested with the tilt board and the shear frame or an improvised version of this tilt test.

CONT

Shovel Shear Test. This test can be done on a flat or on a slope. With good technique, the location of weak layers, even thin weak layers, can be found. First dig a hole or pit in the snow. The vertical wall of the pit should be straight up and down, and smooth. Make a mark on the uphill portion of one corner of your pit with your shovel blade. This will mark the boundaries of your column, which should be roughly 30 cm by 30 cm or 12 inches square.(A) Now, cut both sides using a snow saw or your ski, all the way to the floor of the pit making sure that the cuts are straight.(B) The back of the column should only be cut as deep as your shovel blade is long, so measure with your shovel blade(C) and then cut the back.(D) Next, insert your shovel, blade down, in the back cut of the column and pull gently and evenly forward being careful not to lever your shovel handle.(E) Examine the shear layer where the block failed.(F) The force applied to the shovel that causes a weak layer to shear from the layers surrounding it can be rated as follows : Very easy... Easy... Moderate... Hard...

CONT

The results of the shovel shear test were inconclusive. [Example approved by the Avalanche Bulletin Terminology Standardization Committee.]

OBS

Shovel test: abbreviated form of "shovel shear test." Shovel test may also refer to the shovel tilt test or the shovel compression test.

OBS

Observers are cautioned that identification of the weak layers is the primary objective of the shovel shear test. The shovel shear test is not a stability test.

OBS

shovel shear test: term officially approved by the Avalanche Bulletin Terminology Standardization Committee.

CONT

DEF

Perforated tape [used in irrigation].

CONT

Subsurface drip irrigation is a variation of traditional drip irrigation where the tubing and emitters are buried beneath the soil surface, rather than laid on the ground or suspended from wires. The products being used today in subsurface drip irrigation come in three basic configurations :hard hose, drip tape, and porous tubing.... With drip tapes, the tubing wall thickness from 0. 1 to 0. 5 mm(4-20 mils). The thinner materials are more commonly found in single season or throw away applications, typical of strawberry production. The heavier wall materials ranging from 0. 35 to 0. 50 mm(15-20 mils) are more commonly found in multi-year applications or where the extra strength is required due to stones or other problems identified at the field site.
