Rising Position

Two of the consequences of the temperature rise are not yet in sight flooding to 200 ft above present sea level and, finally, the super greenhouse caused by the exuding of methane, from the tundra as the temperature rises. Positive feedback would lead rapidly to temperatures, which might make the earth s surface uninhabitable (>50°C). 

Ifigh twist profile High twist, low rise, positive cup, and native roll. GC,... 

BIPOLAR PULSE A pulse with two poles that firstly rises positively from the baseline, then goes negatively below the baseline. 

In addition, the flight crew failed to monitor airspeed in relation to the rising position of the low speed cue and to adhere to sterile cockpit procedures, and the captain failed to "effectively manage the flight."... 

In a gas field development, producers are typically positioned at the crest of the reservoir, in order to place the perforations as far away from the rising gas water contact as possible. 

Royalty is charged from the start of production, but tax is only payable once there is a positive taxable income. At the beginning of a new project the fiscal costs may exceed the revenues, giving rise to a negative taxable income. Whether the project can take advantage of this depends upon the fiscal status of the company and the project. 

The field may enter into an economic decline when either income is falling (production decline) or costs are rising, and in many cases both are happening. Whilst there may be scope for further investment in a field in economic decline, it should not tie up funds that can be used more effectively in new projects. A mature development must continue to generate a positive cashflow and compete with other projects for funds. The options that are discussed in this section give some idea of the alternatives that may be available to manage the inevitable process of economic decline, and to extend reservoir and facility life. 

Derive, from simple considerations, the capillary rise between two parallel plates of infinite length inclined at an angle of d to each other, and meeting at the liquid surface, as illustrated in Fig. 11-23. Assume zero contact angle and a circular cross section for the meniscus. Remember that the area of the liquid surface changes with its position. 

As the temperature of the liquid phase is increased, the system ultimately reaches a phase boundary, the bubble point at which the gas phase (vapour) begins to appear, with the composition shown at the left end of the horizontal two-phase tie-line . As the temperature rises more gas appears and the relative amounts of the two phases are detemiined by applying a lever-ami principle to the tie-line the ratio of the fractionof molecules in the gas phase to that hn the liquid phase is given by the inverse of the ratio of the distances from the phase boundary to the position of the overall mole fraction Xq of the system. 

The electrostatic potential at a point is the force acting on a unit positive charge placed at that point. The nuclei give rise to a positive (i.e. repulsive) force, whereas the electrons give rise to a negative potential. The electrostatic potential is an observable quantity that can be determined from a wavefunction using Equations (2.222) and (2.223) ...
