Pressure control in an isolated lower wellbore annulus, defined by a conduit sealably positioned within an isolated lower wellbore segment, is achieved while gravel packing by sensing the pressure within the isolated lower annulus while gravel packing and admitting fluid from the isolated lower annulus into the conduit at one or more discrete locations along the conduit when the sensed pressure corresponds to one or more threshold pressure conditions. The annulus pressure is sensed while gravel packing using a pressure-sensitive device disposed in the annulus, e.g., positioned by the conduit at a high-pressure location. The pressure-sensitive device actuates one or more valves carried along the conduit to admit fluid from the annulus into the conduit at one or more of the discrete locations, and thereby control the pressure in the isolated lower annulus.

A telemetric tibial tray includes a lower plate that defines a plurality of cylindrical transducer cavities having circular load diaphragms. An upper plate is attached to the lower plate through support posts projecting from the load diaphragms. The support posts have a circular cross-section and a diameter of about 5.0 mm. The lower plate further defines wiring channels communicating between the transducer cavities and a central cavity housing the circuit board for the telemetric tray. The wiring channels are arranged at a 45 degree angle relative to the sagittal plane of the knee joint in order to reduce the effects of the wiring channel intersection on the strain sensitivity of the tray. Each transducer cavity includes a radial strain gage array with four pairs of radially aligned strain gages, each pair aligned at a 45 degree angle relative to the sagittal plane of the knee joint. Each pair of strain gages includes an inner gage positioned at the point of maximum positive micro-strain across the diaphragm when loaded, and an outer gage positioned at the point of maximum negative micro-strain, to thereby increase the differential strain measured by the gages and increase the strain sensitivity of the tibial tray.

A semiconductor wafer with a front surface and a back surface and an epitaxial layer of semiconducting material deposited on the front surface, wherein the surface of the epitaxial layer has a maximum density of 0.14 localized light scatterers per cm2 with a cross section of greater than or equal to 0.12 μm, and the front surface of the semiconductor wafer, prior to the deposition of the epitaxial layer, has a surface roughness of 0.05 to 0.29 nm RMS, measured by AFM on a 1 μm×1 μm reference area. There is also a process for producing a semiconductor wafer with a front surface and a back surface and an epitaxial layer of semiconducting material deposited on the front surface. The process includes the following: (a) a stock removal polishing step as the only polishing step; (b) cleaning and drying of the semiconductor wafer; (c) pretreatment of the front surface of the semiconductor wafer at a temperature of from 950 to 1250 degrees Celsius in an epitaxy reactor; and (d) deposition of the epitaxial layer on the front surface of the pretreated semiconductor wafer.

The present invention provides compositions, devices, methods and processes related to the intradermal delivery of PTHrP and PTHrP analogues, particularly [Glu22,25, Leu23,28,31, Aib29, Lys26,30]hPTHrP(1-34)NH2.

Methods for forming a portion of a wellbore are provided. The well is drilled from a first selected depth to a second selected depth to form a bore through a surrounding earth formation. A fluid heating apparatus is disposed within the bore on a working string. Fluid is then heated by moving the fluid through the fluid heating apparatus in the wellbore. The process of circulating fluid adjacent the earth formation serves to also heat the surrounding formation so as to increase the fracture gradient. The fluid heating process may be conducted during a drilling procedure. Alternatively, the fluid heating process may be conducted in connection with a liner hanging and cementing process. A fluid flow restrictor is provided along a run-in assembly that serves to warm the fluids as they are circulated. The warm fluids provide convective heat to the surrounding earth formation, thereby reducing the formation's fracture gradient.

An implant for use in stabilizing vertebral bodies or bones includes a first end and a second end, a tubular section between the first end and the second end having a longitudinal axis. The tubular section is flexible in such a way that it is expandable in a radial direction when a force acts in an axial direction which reduces the distance between the first end and the second end.

Connecting element for joining two support members (2, 3) absorbing tensile forces, which connecting element (1) comprises at least a first and a second casing body (5, 6) with a through-hole (7) for receiving the respective support members (2, 3), which casing bodies (5, 6) can be joined together by way of a joining section (9) at a first end (11) of each casing body (5, 6), the opposing second end (13) of each casing body (5, 6) being provided with locking members (15, 16) for holding the support members (2, 3) fast. In a working position the locking member (15, 16) of at least one casing body (5, 6) produces an axial locking of the support member (2, 3) running through the casing body (5, 6) by way of a stop part (20) created on the support member (2, 3) within the area of the second end (13) of the casing body (5, 6).
