If the patient is unable to perform this motion, the examiner can hold the humerus at 90 degrees of abduction and apply slight pressure to the distal forearm. If the patient's arm falls to their side, this also indicates a rotator cuff dysfunction. Inability to controllably lower the arm can indicate a rotator cuff dysfunction, most commonly the supraspinatus.

Other rover designs that do not use wheeled approaches are possible. Mechanisms that utilize "walking" on robotic legs, hopping, rolling, etc. are possible. For example, Stanford University researchers have proposed "Hedgehog", a small cube-shaped rover that can controllably hop—or even spin out of a sandy sinkhole by corkscrewing upward to escape—for surface exploration of low gravity celestial bodies.

This technology promises creation of viscosity map inside cells and the extracellular milieu. Such nanomotors have been demonstrated to move in blood. Recently, researchers have managed to controllably move such nanomotors inside cancer cells allowing them to trace out patterns inside a cell. Nanomotors moving through the tumor microenvironment have demonstrated the presence of sialic acid in the cancer-secreted extracellular matrix.

Boiler turndown ratio is the ratio of maximum heat output to the minimum level of heat output at which the boiler will operate efficiently or controllably. Many boilers are designed to operate at a variety of output levels. As the desired temperature/pressure point is approached, the heat source is progressively turned down. If pressure/temperature falls, the heat source is progressively turned up.

The basic principle was to use a small air tank to capture, compress and controllably release air power and convert it into mechanical motion. Each Space Pet shipped with a "Tomy air pump" that was used to recharge the air tank. The air pump resembled a bicycle pump, although smaller. The flagship model was the "High Hopping Hoomdorm", which was something of a mechanical grasshopper that would hop furiously (and somewhat erratically) across the room.

In music, a string is the vibrating element that produces sound in string instruments such as the guitar, harp, piano (piano wire), and members of the violin family. Strings are lengths of a flexible material that a musical instrument holds under tension so that they can vibrate freely, but controllably. Strings may be "plain" (consisting only of a single material, like catgut, nylon, or steel). "Wound" strings have a "core" of one material, with an overwinding of other materials.

Freeze-Cast alumina that has been partially sintered. The freezing direction in the image is up. Freeze-casting, also frequently referred to as ice- templating, is a technique that exploits the highly anisotropic solidification behavior of a solvent (generally water) in a well-dispersed slurry to template controllably a directionally porous ceramic. By subjecting an aqueous slurry to a directional temperature gradient, ice crystals will nucleate on one side of the slurry and grow along the temperature gradient.

Joseph Thomas Clover (28 February 1825; baptised 7 May 1825 – 27 September 1882) was an English doctor and pioneer of anaesthesia. He invented a variety of pieces of apparatus to deliver anaesthetics including ether and chloroform safely and controllably. By 1871 he had administered anaesthetics 13,000 times without a fatality. Clover assisted at surgery of public figures including Napoleon III, Princess Alexandra of Denmark and her husband King Edward VII (then Prince of Wales), Sir Robert Peel, and Florence Nightingale.

Strong adhesion may be beneficial in many situations but it also can create difficulties in locomotion. Direction-dependence is an important and fundamental property of adhesive structures that are able to rapidly and controllably adhere during locomotion. Researchers are unsure whether direction-dependence is achieved through changes in contact area or through a change in shear stress. Friction and adhesion forces in most animal attachment organs are higher when they are pulled towards the body than when they push away from it.

The proposed device is characterized from a continuously tunable gain spectrum that selectively amplifies mechanical modes from radio frequency to microwave rates. Viewed as Brillouin process, the system accesses a regime in which the phonon plays the role of Stokes wave. Stokes wave refers to a non-linear and periodic surface wave on an inviscid fluid (ideal fluid assumed to have no viscosity) layer of constant mean depth. For this reason it should be also possible to controllably switch between phonon and phonon laser regimes.

Hydrogen is not an energy resource, except in the hypothetical context of commercial nuclear fusion power plants using deuterium or tritium, a technology presently far from development. The Sun's energy comes from nuclear fusion of hydrogen, but this process is difficult to achieve controllably on Earth. Elemental hydrogen from solar, biological, or electrical sources requires more energy to make than is obtained by burning it, so in these cases hydrogen functions as an energy carrier, like a battery. Hydrogen may be obtained from fossil sources (such as methane), but these sources are unsustainable.

Precharging a high voltage DC power distribution line can control the inrush current into capacitive components, reducing stress and supporting a long component life. The functional requirement of the high voltage pre-charge circuit is to minimize the peak current out from the power source by slowing down the dV/dT of the input power voltage such that a new "pre-charge mode" is created. Of course the inductive loads on the distribution system must be switched off during the precharge mode. While pre-charging, the system voltage will rise slowly and controllably with power-up current never exceeding the maximum allowed.

Rand Corporation The publication of the study renewed controversy over how people suffering a disease which reputedly leads to uncontrollable drinking could manage to drink controllably. Subsequent studies also reported evidence of return to controlled drinking.Heather, N., & Robertson, I. (1981). Controlled drinking. London: Methuen Similarly, according to a 2002 National Institute on Alcohol Abuse and Alcoholism (NIAAA) study, about one of every six (18%) of alcohol dependent adults in the U.S. whose dependence began over one year previously had become "low-risk drinkers" (less than 14 drinks per week and 5 drinks per day for men, or less than 7 per week and 4 per day for women).

The sensitive dependence of a semiconductor's properties on dopants has provided an extensive range of tunable phenomena to explore and apply to devices. It is possible to identify the effects of a solitary dopant on commercial device performance as well as on the fundamental properties of a semiconductor material. New applications have become available that require the discrete character of a single dopant, such as single-spin devices in the area of quantum information or single-dopant transistors. Dramatic advances in the past decade towards observing, controllably creating and manipulating single dopants, as well as their application in novel devices have allowed opening the new field of solotronics (solitary dopant optoelectronics).

In this regard, using trioctylphosphine oxide (TOP) as the phosphorus precursor with an approximately six-fold larger molecular footprint than DPP, the dopant dose can be modulated in the reduction of six times accordingly. Moreover, the doping profiles can be readily tuned through optimization of the annealing conditions. In this case, the high surface doping density with sharp spatial decay can be obtained by using this MLD method with low anneal temperatures and short times for the formation of USJs. The ability to controllably tune the dopant dose through the structural design of the precursor and to control the dopant profile by the annealing conditions present a unique aspect of the MLD process for attaining the desired dopant dose and profile.

Since several key publications on using AAO for bottom-up templated nanofabrication appeared by the mid-1990s, AAO became widely recognized and very popular platform for design and synthesis of high density arrays of nanostructures (nanowires, nanotubes) and functional nanocomposites. AAO-based nanomaterials have a broad range of applications, from nanoelectronics and magnetic storage media to photonics and energy conversion to nanoporous substrates and nanotags for bioanalysis. The number of AAO-related publications in this area increased exponentially since 1990s,Web of Science database with over 75% of the papers focused on use of AAO in nanotechnology. The significance of AAO in science and technology is underpinned by the fact that its structure and chemistry could be controllably engineered at the nanoscale over very large areas and in practical formats, enabling development of new materials and products with desired properties and functionality.

Roches du Diable Creeking is perhaps best thought of as a subcategory of river running, involving very technical and difficult rapids, typically in the Grade/Class IV to VI range. While people will differ on the definition, creeking generally involves higher gradient, approaching or in excess of 100 ft per mi (19 m per km), and is likely to include running ledges, slides, and waterfalls on relatively small and tight rivers, though some will allow for very large and big volume rivers in their definition. Canoes used for creeking usually have higher volume (more gallons or liters of displacement) and more rounded bow and stern, as these features provide an extra margin of safety' against the likelihood of pinning, and will resurface more quickly and controllably when coming off larger drops. Creek boats usually have increased "rocker," or rise, on the bow to go up and over obstacles and obstructions within the river, it is a continuous rocker which means that the curvature of the bottom of the boat is a constant curve so there is less water contact.

By planting his right elbow against his stomach at the same point each time, he establishes a constant reference point from which the subconscious can easily determine the parallax between the direct line-of-sight of the shooter's eyes and his gun barrel. Also, with his elbow planted in his stomach, the shooter has greater leverage for pulling the trigger of a double- action revolver or automatic controllably. The only real variable that the shooter's subconscious now has to deal with is figuring out how much bend to put in his elbow to get the vertical alignment correct for the offset of the gun barrel and the distance to the target. McDaniel would have the student practice his quick-draw until it was smooth and certain, and consequently fast. When the time came to hip-shoot the handgun, McDaniel would have the student shoot into soft dirt, to observe his hits and misses, at a location that was backstopped by a 20 or 30 foot dirt bank, to stop any ricochets or wild shots.

Creek boats usually have increased "rocker," or rise, fore and aft of the cockpit for manoeuvrability.
