Distribution data describing the current shea range were obtained from John Hall (University of Wales, Bangor); for details, see previous reports and Vitellaria paradoxa: a monograph (Hall et al., 1996). In 2010, these records were supplemented with shea plot data from Burkina Faso, Mali and Ghana, and with the collection localities of herbarium specimens held at the Royal Botanic Gardens, Kew ...

We study the problem of on-line searching for a target inside a polygon. In particular, we propose a strategy for finding a target of unknown location in a star-shaped polygon with a competitive ratio of 11.52. We also provide a lower bound of 9 for the competitive ratio of searching in a star-shaped polygon which is close to the upper bound. A similar task is the on-line recognition of a star-...

The cell membrane of the unicellular algae Distigma proteus is associated with arrays of parallel microtubules. Fragments of the membrane-microtubule complex have been isolated and partially purified. The microtubules were stable in vitro at room temperature as well as at 0 degree C, but were specifically and rapidly disassembled by Ca2+. After removal of all endogenous microtubules, the membra...

It is well known that TCP does not fully utilize the available bandwidth in fast long-distance networks. Several high speed transport protocols have been proposed in an effort to solve this scalability problem. This paper proposes S-shaped TCP (SS-TCP). The window growth function of SS-TCP is, in the steady state, S-shaped, and it can be divided into three regions. In region I, the window growt...

In this paper, direct estimate of Sobolev exponent of reenable distributions and its application to the asymptotic estimate of Sobolev exponent of M band Daubechies' scaling functions are considered.

In this work, we numerically study laminar flows in forced convection a U -shaped channel. Our was based on finite volume method by the fluent code carried out for Reynolds number varying range 100<Re<700, and Rayleigh Ra=105 Prandtl Pr=0.72. As function of number, results obtained are presented form thermal dynamic field, variation Nusselt speed average temperature at outlet channel as R...

The article presents the results of a study lubricant flow in narrow wedge-shaped slot with movable wall. A solution to problem slip boundary conditions on channel walls is obtained. effect slippage change hydrostatic lift and hydraulic resistance slotted shown.
 It was determined work that an increase intensity (an value Knudsen number), pressure variation weakens. This due weakening inte...

The 63-kDa fragment of the protective antigen (PA) component of anthrax toxin forms a heptameric channel, (PA63)7, in acidic endosomal membranes that leads to the translocation of edema factor (EF) and lethal factor (LF) to the cytosol. It also forms a channel in planar phospholipid bilayer membranes. What role does this channel play in the translocation of EF and LF? We report that after the 2...
