Abstract: The invention relates to a method for connecting a connection piece to a U-shaped ring anchor for a head module for rail vehicles, the head module consisting predominantly of fiber-reinforced plastic material and having an outer shell and the ring anchor consisting of fiber-reinforced plastic material and being arranged in the roof region of the outer shell as a stiffening means. According to the method, connecting elements are fed through the dry or matrix-material-impregnated, unconsolidated fiber reinforcement structure of the ring anchor.

Abstract: The titanium-containing oxide slag, low-purity silicon and slagging fluxes are subject to reduction smelting together, and a bulk Si—Ti intermediate alloy is obtained by slag-metal separation; the obtained bulk Si—Ti intermediate alloy is crushed into Si—Ti intermediate alloy particles; and the obtained Si—Ti intermediate alloy particles are used as an anode, metallic molybdenum or metallic nickel as a cathode, metallic titanium as a reference electrode, and NaCl—KCl—NaF together with small amounts of Na3TiF6 or K3TiF6 as a molten salt, to carry out the electrolysis under a high-purity argon atmosphere at a temperature of 973 K. Ti in the Si—Ti intermediate alloy particles dissolved at the anode and deposited at the cathode, while Si in the Si—Ti intermediate alloy particles fell off from the anode as metallic silicon powder.

Abstract: A single-shot pulse contrast measuring device based on non-harmonic long-wavelength sampling pulse includes a long-wavelength sampling light generation unit, a large-angle non-collinear sum-frequency cross-correlation unit and a high sensitivity signal receiving unit. The long-wavelength sampling light sum-frequency cross-correlator can allow that the beams are interacted with each other at the large non-collinear angle in the quasi-phase matching crystal, match the measuring window of the high sensitivity signal receiving system, and is in favor of eliminating the scattered light noise, thereby achieving the single measurement of the pulse contrast with large temporal window and high dynamic range. The single-shot pulse contrast measuring device of the present invention has good extensibility at the temporal window and dynamic range, and is adapted for measuring the contrast of the high-power laser with various wavelengths.

Abstract: A curved suture applicator is provided for facilitation of ligation procedures in mammals. The said curved suture applicator enables a surgeon to efficiently encircle a target tissue such as a blood vessel with a suture or thread. A kit is also provided, comprising the said curved suture applicator, an appropriate length of suture or thread, and a suture manipulation device, such as a pair of forceps. Furthermore, a minimally invasive ligation method is provided that utilizes the said curved suture applicator and kit to efficiently band the transverse aorta of small mammals. Such banding is useful in studying and simulating the effects of left ventricular hypertrophy as it relates to congenital heart failure.
