Tree uprooting. Uprooting is a form of treefall in which the root plate of a tree is torn from the soil, disrupting and mixing it and leaving a pit-mound.

Purposes

Transplanting 
Small trees can be replanted if their root system is well attached to the trunk. Trees can suffer from transplant shock when moved to new environment, and that causes the tree not to be able to root itself properly.

Ecosystem maintenance 
Uprooting can be an effective method for efforts to remove unwanted woody species from an ecosystem, e.g., in the context of woody plant encroachment.

Vujica Jevđević. Vujica Jevđević (Vujica M. Yevjevich) (12 October 1913 – 26 March 2006) was a Yugoslav hydrologist and educator. 

He was the founder and the first director of the Hydroenergetic Institute in Belgrade and the Hydraulic Laboratory, institutions that led the construction of hydroelectric power plants in post-WW2 Yugoslavia. In the US, Jevđević was the director of the International Water Resources Institute at George Washington University and professor in the engineering department at Colorado State University.

Biography 

Jevđević graduated from the University of Belgrade before doing a specialisation in hydrology at the University of Grenoble. During World War 2 he was a war prisoner of the Axis troops, and in 1944 he successfully returned to the liberated Belgrade and joined the newly formed Ministry of Construction. He led the establishment of the new institutes for and hydroenergy, and returned to the University of Belgrade as a lecturer. There he defended his doctoral thesis in 1955 as Yugoslavia's first doctor in hydrology..

In the following years, he was a visiting scientist for the U.S. National Bureau of Standards and for the U.S. Geological Survey in Washington, D.C. before taking the professorial post at Colorado State University where he taught hydro-engineering. He was also the  Director of the International Water Resources Institute at George Washington University in Washington, D.C. Jevđević won many awards during his prolific academic career, including the inaugural 1996 Ven Te Chow Award of ASCE, inaugural 1988 Ven Te Chow Award of IWRA, as well as IAHS International Hydrology Award in 1987

Jevđević died in 2006 after a long battle with Parkinson's disease.

At the time of his death, he was finishing a seven-volume autobiography.

Repeat instruction. In computer instruction set architectures (ISA), a repeat instruction is a machine language instruction which repeatedly executes another instruction a fixed number of times, or until some condition is met.

Since it is an instruction that operates on other instructions like the execute instruction, it has been classified as a meta-instruction.

Computer models

The Univac 1103 (1953) includes a repeat instruction (op code mnemonic: ) which executes the following instruction a fixed number of times, possibly incrementing one or both of the address fields of that instruction. This compensates for the architecture's lack of index registers.

The GE-600/Honeywell 6000 series (1964) supports a single-instruction repeat (), a double-instruction repeat (), and a linked-list repeat ().

The x86 ISA, starting with the 8086, includes a series of special-purpose repeat instructions () which are called "repeat string operation prefixes" and may only be applied to a small number of string instructions (). These instructions repeat an operation and decrement a counter until it is zero, or may also stop when a certain condition is met.

The Texas Instruments TMS320 digital signal processor (1983) includes an instruction for repeating a single-cycle instruction or two single-cycle instruction in parallel () and an instruction for repeating a block of instructions (). These use special block-repeat counter registers ().

Semantics

The instruction or instruction pair to be executed follows the repeat instruction. Fields in the instruction determine the loop termination condition. In the case of the TMS320, a block of up to 64Kbytes can be repeated.

Balloon popping. A balloon pops when the material that makes up its surface tears or shreds, creating a hole. Normally, there is a balance of the balloon skin's elastic tension in which every point on the balloon's surface is being pulled by the material surrounding it. However, if a hole is made on the balloon's surface, the force becomes imbalanced, since there is no longer any force exerted by the center of the hole on the material at its edge. As a result, the balloon's surface at the edge of the hole pulls away, making it bigger; the high pressure air can then escape through the hole and the balloon pops. A balloon can be popped by either physical or chemical actions. Limpanuparb et al. use popping a balloon as a demonstration to teach about physical and chemical hazards in laboratory safety.

Physical 

A pin or needle is frequently used to pop a balloon. As the needle or pin creates a hole on the balloon surface, the balloon pops. However, if tape is placed on the part where the hole is created, the balloon will not pop since the tape helps reinforce the elastic tension in that area, preventing the edges of the hole pulling away from the center. Likewise, the thick spots of the balloon at the top and the bottom can be pierced by a needle, pin, or even skewer without the balloon popping.

Chemical

Organic solvent 

Applying an organic solvent such as toluene onto a balloon's surface can pop it, since the solvent can partially dissolve the material making up the balloon's surface.

cis-1,4-polyisoprene (solid) + organic solvent → cis-1,4-polyisoprene (partly dissolved)

Baby oil can also be applied to water balloons to pop them.

Orange peel 
Orange peel contains a compound called limonene which is a hydrocarbon compound similar to the rubber that can be used to make balloons. Based on "like dissolves like" principle, rubber balloons can be dissolved by limonene, popping the balloon. If the balloon is vulcanized (hardened with sulfur), the balloon will not pop.

Thrust (particle physics). In high energy physics, thrust is a property, (one of the event shape observables) used to characterize the collision of high energy particles in a collider.

When two high energy particles collide, they typically produce jets of secondary particles. This happens when one or several quark-antiquark pairs are produced during the collision. Each colored quark/antiquark pair travels its separate way and subsequently hadronizes. Many new particles are created by the hadronization process and travel in approximately the same direction as the original pair. This set of particles constitutes a jet.

The thrust quantifies the coherence, or ″jettiness″ of the group of particles resulting from one collision. It is defined as:

,

where  is the momentum of particle , and  is a unit vector that maximizes  and defines the thrust axis. The sum is over all the final particles resulting from the collision. In practice, the sum may be carried over the detected particles only.

The thrust  is stable under collinear splitting of particles, and therefore it is a robust observable, largely insensitive to the details of the specific hadronization process.

Likens-Nickerson Apparatus. The Likens-Nickerson apparatus is a piece of laboratory glassware devised by Sam T. Likens and Gail B. Nickerson for the detection of hop oil constituents in 1964. The apparatus performs a simultaneous steam distillation and extraction. The apparatus is typically constructed of borosilicate glass with the cold finger condenser and boiling flasks fitted with ground glass joints. It is typically used to isolate target organic compounds for further quantitative and or qualitative analysis using instrumental chemistry. However, it can also be used to isolate target compound(s) from an aqueous solution as a way of recovering valuable material.

Description and operation 

The unusually shaped Likens-Nickerson apparatus uses two boiling flasks.  One flask is loaded with an aqueous solution containing the desired compound(s) and the other with immiscible organic solvent.  Each flask is allowed to reach their respective boiling points thus sending their vapors (or aerosolized oils) along the arms of the apparatus to the central cold finger condenser where they emulsify, condense, and fall into a separatory trap that may or may not have a stopcock.  The arms of the trap leading back to the original vapor path can be configured in such a way as to return either the aqueous or organic layer to its respective flask.

History 
Since its invention in 1964 the apparatus has been adopted, modified, and used by hundreds of researchers for the purposes of analyzing compounds in everything from fermented camels milk to turbot. Perhaps the most notable permutation of the Likens-Nickerson apparatus is the device described by Godefroot et al. in 1981. However, researchers have constructed and used countless variations that allow the apparatus to operate under a vacuum, be filled with inert gas, or be continuously operated. Yet they all acknowledge the Likens-Nickerson apparatus as having informed their respective design.
