The redomiciled Gibraltar-based corporate family now describes itself a virtual business. Borealis previously had an Industry Classification 1382 – Oil and gas exploration services, and owns subsidiaries dealing with materials and power transfer. Borealis Exploration has been under a cease trade order in Canada since September 13, 2001, for continuing failure to submit information required in an inquiry by the Ontario Securities Commission. The Alberta Securities Commission has been allowing variations on this cease trade order with exceptions being made for Canadian shareholders since the company's operations are located outside Canada, its head office is located in Gibraltar, and its securities are not listed on and do not trade on any ex ...

Return On Assets
The return on assets (ROA) shows the percentage of how profitable a company's assets are in generating revenue. ROA can be computed as below: :\mathrm = \frac This number tells you what the company can do with what it has, ''i.e.'' how many dollars of earnings they derive from each dollar of assets they control. It's a useful number for comparing competing companies in the same industry. The number will vary widely across different industries. Return on assets gives an indication of the capital intensity of the company, which will depend on the industry; companies that require large initial investments will generally have lower return on assets. ROAs over 5% are generally considered good. Usage Return on assets is one of the elements used in financial analysis using the Du Pont Identity.

AC Induction Motor
An induction motor or asynchronous motor is an AC electric motor in which the electric current in the rotor needed to produce torque is obtained by electromagnetic induction from the magnetic field of the stator winding. An induction motor can therefore be made without electrical connections to the rotor. An induction motor's rotor can be either wound type or squirrel-cage type. Three-phase squirrel-cage induction motors are widely used as industrial drives because they are self-starting, reliable and economical. Single-phase induction motors are used extensively for smaller loads, such as household appliances like fans. Although traditionally used in fixed-speed service, induction motors are increasingly being used with variable-frequency drives (VFD) in variable-speed service. VFDs offer especially important energy savings opportunities for existing and prospective induction motors in variable-torque centrifugal fan, pump and compressor load applications. Squirrel-cage ...

Torque
In physics and mechanics, torque is the rotational equivalent of linear force. It is also referred to as the moment of force (also abbreviated to moment). It represents the capability of a force to produce change in the rotational motion of the body. The concept originated with the studies by Archimedes of the usage of levers, which is reflected in his famous quote: "''Give me a lever and a place to stand and I will move the Earth''". Just as a linear force is a push or a pull, a torque can be thought of as a twist to an object around a specific axis. Torque is defined as the product of the magnitude of the perpendicular component of the force and the distance of the line of action of a force from the point around which it is being determined. The law of conservation of energy can also be used to understand torque. The symbol for torque is typically \boldsymbol\tau, the lowercase Greek letter '' tau''. When being referred to as moment of force, it is commonly denoted by . ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AC Motor
An AC motor is an electric motor driven by an alternating current (AC). The AC motor commonly consists of two basic parts, an outside stator having coils supplied with alternating current to produce a rotating magnetic field, and an inside rotor attached to the output shaft producing a second rotating magnetic field. The rotor magnetic field may be produced by permanent magnets, reluctance saliency, or DC or AC electrical windings. Less common, AC linear motors operate on similar principles as rotating motors but have their stationary and moving parts arranged in a straight line configuration, producing linear motion instead of rotation. Operating principles The two main types of AC motors are induction motors and synchronous motors. The induction motor (or asynchronous motor) always relies on a small difference in speed between the stator rotating magnetic field and the rotor shaft speed called slip to induce rotor current in the rotor AC winding. As a result, the induction mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Harmonics
A harmonic is a wave with a frequency that is a positive integer multiple of the '' fundamental frequency'', the frequency of the original periodic signal, such as a sinusoidal wave. The original signal is also called the ''1st harmonic'', the other harmonics are known as ''higher harmonics''. As all harmonics are periodic at the fundamental frequency, the sum of harmonics is also periodic at that frequency. The set of harmonics forms a '' harmonic series''. The term is employed in various disciplines, including music, physics, acoustics, electronic power transmission, radio technology, and other fields. For example, if the fundamental frequency is 50 Hz, a common AC power supply frequency, the frequencies of the first three higher harmonics are 100 Hz (2nd harmonic), 150 Hz (3rd harmonic), 200 Hz (4th harmonic) and any addition of waves with these frequencies is periodic at 50 Hz. In music, harmonics are used on string instruments and wind i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Alternating Current
Alternating current (AC) is an electric current which periodically reverses direction and changes its magnitude continuously with time in contrast to direct current (DC) which flows only in one direction. Alternating current is the form in which electric power is delivered to businesses and residences, and it is the form of electrical energy that consumers typically use when they plug kitchen appliances, televisions, fans and electric lamps into a wall socket. A common source of DC power is a battery cell in a flashlight. The abbreviations ''AC'' and ''DC'' are often used to mean simply ''alternating'' and ''direct'', as when they modify '' current'' or '' voltage''. The usual waveform of alternating current in most electric power circuits is a sine wave, whose positive half-period corresponds with positive direction of the current and vice versa. In certain applications, like guitar amplifiers, different waveforms are used, such as triangular waves or square waves. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nunavut
Nunavut ( , ; iu, ᓄᓇᕗᑦ , ; ) is the largest and northernmost territory of Canada. It was separated officially from the Northwest Territories on April 1, 1999, via the '' Nunavut Act'' and the '' Nunavut Land Claims Agreement Act'', which provided this territory to the Inuit for independent government. The boundaries had been drawn in 1993. The creation of Nunavut resulted in the first major change to Canada's political map in half a century since the province of Newfoundland was admitted in 1949. Nunavut comprises a major portion of Northern Canada and most of the Arctic Archipelago. Its vast territory makes it the fifth-largest country subdivision in the world, as well as North America's second-largest (after Greenland). The capital Iqaluit (formerly Frobisher Bay), on Baffin Island in the east, was chosen by a capital plebiscite in 1995. Other major communities include the regional centres of Rankin Inlet and Cambridge Bay. Nunavut also includes Ellesme ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Freuchen Bay
Lorenz Peter Elfred Freuchen (20 February 1886 – 2 September 1957) was a Danish explorer, author, journalist and anthropologist. He is notable for his role in Arctic exploration, namely the Thule Expeditions. Personal life Freuchen was born in Nykøbing Falster, Denmark, the son of Anne Petrine Frederikke (née Rasmussen; 1862–1945) and Lorentz Benzon Freuchen (1859–1927). His father was a businessman. Freuchen was baptized in the local church. He attended the University of Copenhagen where for a time he studied medicine. Freuchen was married three times. He was first married in 1911 to Navarana Mequpaluk (d. 1921), an Inuk woman who died in the Spanish Flu epidemic after bearing two children (a boy named Mequsaq Avataq Igimaqssusuktoranguapaluk (1916 - c. 1962) and a girl named Pipaluk Jette Tukuminguaq Kasaluk Palika (1918–1999)). His second marriage was to (1881–1960), daughter of (1847-1920), Danish businessman and director of Danmarks Nationalbank. The ...
