The excess second virial coefficient for (1,1,1,2-tetrafluoroethane + propane) has been measured at temperatures of 299.5 K, 313.15 K, 328.15 K, and 343.15 K, using the pressure-change-on-mixing method. The excess enthalpy and unlike-in...

We give simple necessary and sufficient conditions for the existence of a zero-one matrix with given row and column sums Nike Free 3 Womens Canada and at most one structural zero in each row and column. On process plants, thermal insul...

It is shown that on closed disks D around the origin in the complex plane and for every integer m ≥ 2, not every continuous function on D can be approximated uniformly on D by polynomials in zm and <img height="31" border="0" style...

New results concerning flashlamp pumped, colour centre lasers using F+2 centres in LiF:OH- at Nike Free 3 Vs 5 77 K are reported. We study the thermal effects and we measure the threshold, the losses and Nike Free Run 5.0 Review the gai...

This paper introduces the concept of a partial geometry of dimension three, extending the concept of an (r, k, t) partial geometry (which may be called of dimension two) due to Bose. An association scheme is defined on this system which...

In this paper, we investigate the existence of multiple positive periodic solutions to a class of functional difference equations. We answer the open problems proposed by Y. Raffoul in [Electron. J. Differential Equations 55 (2002) 1–...

We study a probabilistic algorithm for the computation of the centroidal Voronoi tessellation which is a Voronoi tessellation of a given set such that the associated generating points are centroids (centers of mass) of the corresponding...

The preparation for DNA replication initiation is tightly linked to cell-cycle progression, ensuring that replication occurs only once per cycle. The time is ripe for a molecular dissection of the links between the two processes. We us...

The size of an organism is determined by the number and size of its constituent cells. The insulin/IGF-1 signaling systems have been long recognized to play a critical role in the determination of body size. Now the generation of mice d...

In this work we establish a 2-categorical analogue of Beck's theorem characterizing monadic functors. We show that a 2-functor (a pseudo-functor) U is monadic iff it is a right pseudo-adjoint, it reflects adjoint equivalences and it cre...
