For the central tracking chamber of the JADE detector [l] at the e+estorage ring PETRA a new type of drift chamber, the so-called jet chamber, has been developed [Z-4]. This chamber is capable of recording events of high local track density (jets) with good space and double track resolution and with the possibility of particle identification within a solid angle close to ~I'I sterad. The concep...

It has been well established that the trophocytes, or nurse cells of heteropterous ovaries, contribute a variety of cytoplasmic components to the developing oocytes (Bonhag, 1958) . Hemipteran ovaries are of the telotrophic type in which the nurse cells are confined to the apical trophic-chamber of each ovariole and are connected to developing oocytes, during their early stages of differentiati...

In vitro brain slice electrophysiology is a powerful and highly successful technique where a thin slice is cut from the brain and kept alive artificially in a recording chamber. The design of this recording chamber is pivotal to the success and the quality of such experiments. Most often one of two types of chambers is used today, the interface chamber or the submerged chamber. These chambers, ...

This research deals with heat and mass transfer in biscuit industrial baking ovens. In these ovens, heat reaches biscuits indirectly by radiation, convection and conduction. The method for numerical solution is that we first provide the related equations, then they are discretized by finite difference method (FDM), and finally, after encoding and writing a program for the computer, we run it. T...

A numerical study was performed to investigate the applicability of linear decomposition method for hydrodynamic energy conversion an oscillating-water-column type wave converter (OWC-WEC). Hydrodynamic problems OWC chamber were decomposed into excitation and radiation with time-domain based on potential theory. finite element applied solve flow in entire fluid domain including structure. The v...
