Abstract: A method of providing a casing in a well is disclosed in which casing comprising a series of casing sections, the first section of which is provided from the top of the well and the subsequent sections arranged progressively downwards therefrom, are lowered into the well sequentially by a suitable lowering means such as a coiled tubing runner. Well fluids which are displaced by the lowering of the subsequent sections and the lowering means pass from the lower portion of the well up through the internal bore of the sections. The displaced fluids pass out from the internal bore of the lowering means into an outside annulus between the lowering means and existing casing sections through radial closable openings or side valves. A lockable non return valve, provided at the lower end of the section to be fitted, normally permits flow downwardly out of the casing and prevents flow upwardly into the casing, but may be optionally arranged in a locked open position to permit the well fluids to flow inside the internal bore of the sections to be fitted. The invention also relates to a lowering tool which enables the casing sections to be lowered and permits the well fluids to flow out into the adjoining channel.

Abstract: A method and apparatus for generating and controlling the propagation of electrons in a semiconductor material using a plurality of beams of coherent light is disclosed. The direction and magnitude of propagation of the electrons in the semiconductor are controlled by varying the polarization of the coherent beams with respect to the semiconductor material, and in particular the crystallographic axis of the semiconductor material.  The electrons are generated and controlled by use of three coherent beams which are related such that the frequency of one of the beams is substantially equal to the sum of the frequencies of the other beams, and the first beam produces substantially the same number of electrons in the semiconductor material that the other beams produce together.  A selected region of the semiconductor material is simultaneously irradiated with all of the beams of light.  The semiconductor material is at approximately room temperature.  Holes are also generated and propagate in a direction opposite to the direction of propagation of the electrons.

Abstract: Dans l'exon 5 du facteur 1 associé à l'asthme humain, une transition de T à C de l'acide nucléique de la position 3365 produit la substitution prévue des acides aminés, celle d'une méthionine qui remplace une thréonine, au codon 117 de ce facteur. Quand cette substitution intervient dans les deux allèles d'un même sujet, elel est associée à une prévalence moindre des allergies atopiques, y compris l'asthme, à moins de réactions anormales aux tests cutanés, et à un niveau total moindre de l'IgE sérique. Le déposant a donc identifié l'existence d'un phénotype, non lié à l'asthme et non atopique, caractérisé par la méthionine du codon 117 lorsqu'elle est présente dans les deux produits géniques du facteur 1 associé à l'asthme humain chez un même sujet.

Abstract: A tube of porous PTFE having at least two first and at least two second regions wherein the at least two first regions have a greater density than the at least two second regions. For tubes of porous expanded PTFE having a microstructure of nodes interconnected by fibrils, the at least two first regions have a mean fibril length that is less than that of the at least two second regions. Preferably the regions are arranged in the form of ring-shaped segments of the tube wherein denser segments alternate along the length of the tube with less dense segments. Other arrangements between the different regions are possible; for example, the regions may be oriented in a spiral relationship with each other along the length of the tube. The porous PTFE tubes of the present invention have excellent radial compression resistance without requiring additional exterior reinforcing members due to the presenc e of the denser regions that are provided with a circumferential orientation. Tubes of this type are anticipated to be useful as vascular grafts and particularly as intraluminal vascular grafts. When provided as an intraluminal graft, the tube may also optionally be manufactured to be circumferentially distensible to a larger diameter up to a maximum diameter beyond which it will not distend during normal use;such a tube can also be made to recoil minimally on the release of the distending force.

Abstract: A method of manufacturing a double walled vessel is herein disclosed. The method involves the steps of forming an outer vessel having at least one reassembly channel formed therearound and forming an inner vessel having at least one element fitting formed integral thereto. At least one control housing is secured to the outer surface of the inner shell in registration with the element fitting.  Heating elements and other control apparatus are installed in the element fittings within the control boxes. The outer vessel is sectioned at the reassembly channel, thereby allowing the inner vessel to be inserted into the outer vessel. The outer vessel is reassembled to enclose the inner vessel therein and a curable foam material is injected into the space between the inner and outer vessels to maintain a constant spatial relationship therebetween and to ensure the structural integrity of the outer vessel. Finally, a portion of the wall of the outer vessel corresponding to an open face of the control housing is removed to permit access to the interior of the control housing through the wall of the outer vessel.
