The installed backpressure power generation capacity at Hippo Valley Estates (HVE) comprised a number of old and small sets, which had become inadequate to reliably supply the total power requirements of the mill and estate. A new 20 MW backpressure turbine alternator (TA) was installed to satisfy the full factory demand on its own and export a surplus to the national grid. The project was comp...

We found a new symplectic structure and a recursion operator for the Sasa–Satsuma (complex mKdV II) equation widely used in nonlinear optics, pt = pxxx + 6pqpx + 3p(pq)x, qt = qxxx + 6pqqx + 3q(pq)x, along with an integro-differential substitution linking this system to a third-order generalized symmetry of the complex sine-Gordon II system uxy = vuxuy uv + c + (2uv + c)(uv + c)ku, vxy = uvxvy ...

Recent developments in advanced quantum chemistry and quantum chemistry interfaced with model potentials are discussed, with the primary focus on new implementations in the GAMESS electronic structure suite of programs. Applications to solvent effects and surface science are discussed.

The Shabat equation f 0 (t) + q 2 f 0 (qt) + f 2 (t) ? q 2 f 2 (qt) = ; t 2 R; where and q are parameters, is the simplest self-similar reduction of the so called dressing chain for constructing and analysing exactly solvable Schrr odinger equations. It is also relevant to the study of the q-oscillator algebra in quantum mechanics. The main objective of this paper is to investigate whether the ...

This paper deals with a realistic turbine simulator that uses a 20 kW DC motor with an independent excitation and mntmlled hy a microcompiiter. The tiirhine torque and rotation are both simnlated according to wind and load of actually driven generators with any type of rctuql loads. With the help of this simulator it is possible to develop and realise tests in electrical power plants in conditi...

Phenylalanine (Phe) kinetics are increasingly used in studies of amino acid kinetics, because the metabolic fate of Phe is limited to incorporation into protein (protein synthesis, Sp) and catabolism via hydroxylation ( Q pt) to tyrosine (Tyr). Besides an infusion of labeled Phe to measure Phe flux ( Q p), a priming dose of Tyr and an independent Tyr tracer are used to measure Tyr flux ( Q t) a...

The P-positions of the well-known 2-pile take-away game of Wythoff Nim lie on two ‘beams’ of slope √ 5+1 2 and √ 5−1 2 respectively. We study extensions to this game where a player may also remove simultaneously pt tokens from either of the piles and qt from the other, where p < q are given positive integers and where t ranges over the positive integers. We prove that for certain pairs (p, q) t...

Fig. 1. Squared-cross-correlation as a function of lag between (a) the predictions of M1 and Antarctic temperatures, and (b) M2 predictions Schmittner et al. (2003) argue that during the last glacial period, at millennial timescales, temperature changes in Greenland preceded changes of the opposite sign in Antarctica by 400–500 yr. They provide support for this conclusion by comparing a simple ...
