Abstract

A powder metal composition for high wear and temperature applications is made by atomizing a melted iron based alloy including 3.0 to 7.0 wt. % carbon; 10.0 to 25.0 wt. % chromium; 1.0 to 5.0 wt. % tungsten; 3.5 to 7.0 wt. % vanadium; 1.0 to 5.0 wt. % molybdenum; not greater than 0.5 wt. % oxygen; and at least 40.0 wt. % iron. The high carbon content reduces the solubility of oxygen in the melt and thus lowers the oxygen content to a level below which would cause the carbide-forming elements to oxidize during atomization. The powder metal composition includes metal carbides in an amount of at least 15 vol. %. The microhardness of the powder metal composition increases with increasing amounts of carbon and is typically about 800 to 1,500 Hv50.

Abstract

It has been discovered that compositions comprising magnetically heatable entities (MHEs), therapeutic agents and optional carriers such as hydrogels can be piloted from an injection point in a blood vessel to a specific location of the blood-brain barrier (BBB) using for example, a magnetic resonance imaging (MRI) device for propelling, steering and tracking of MHEs. Once the MHEs have reached their target location at or near the desired blood vessel of the BBB, an alternating magnetic field causes the MHEs to controllably heat up, thereby reversibly increasing the permeability of the BBB and allowing the therapeutic (or cytotoxic) agent to enter brain tissue.

Abstract

Antenna units, antenna systems and polarizing systems provide polarization diversity to leaky-wave antennas. An antenna unit comprises a rat- race coupler having a summation port, a difference port and two output ports. Each one of a pair of composite right/left-handed (CRLH) leaky-wave antennas (LWA) is connected at one end to a respective one of the output ports of the rat- race coupler. An inductive stub is implemented between the CRLH LWAs for connecting the CRLH LWAs to a grounded via. Various polarizations are obtained by injecting a radio-frequency (RF) signal in the summation or difference port of the rat-race coupler, or in both ports. System variants include various devices and assemblies for injecting RF signals in the antenna unit. One such variant includes a polarizing system having a switched matrix for directing a signal according to various intended polarizations.

Abstract

Chitosan delivers a plasmid encoding Glucagon-Like Peptide 1 (GLP-1) to cells in a patient for gene therapy of diabetes. Chitosan is optimized for plasmid transfection by modulating three of its physico-chemical properties: degree of deacetylation (DDA), molecular weight (MW), and ratio of amines on chitosan to phosphates on DNA (N:P ratio), Chitosan 92-10-5 (DDA-MW-N:P) is more efficient than chitosans 80-10-10 and 80-80-5 in delivering a plasmid encoding luciferase or GLP- 1(7-37) to cells. In the Zucker Diabetic Fatty (ZDF) rat model of diabetes, chitosan-delivered pVax plasmid encoding GLP-1 lowers glucose levels, increases insulin production and reduces weight gain.

Abstract

The present invention relates to a dynamic radiation pattern antenna system comprising a plurality of antenna units, a control unit and an electronic interface. The plurality of antenna units has electronically controllable radiation patterns. The control unit is dynamically controlling the radiation pattern of the plurality of antenna units and the electronic interface connects the plurality of antenna units to the control unit.

Abstract

A method for making a porous material, includes melt-blending two or more non-miscible polymers to obtain a co-continuous melt, solidifying the melt to obtain a solid mass consisting of two co-continuous polymer phases, and selectively extracting one of the co-continuous phases thereby creating within the solid mass an essentially continuous pore network having an internal surface. The method further includes replicating the internal surface of the pore network within the solid mass by coating the internal surface with successive layers of materials, and selectively extracting the solid mass without extracting the layers of materials, to thereby yield the product porous material, formed of the layers of materials. The material has a void fraction higher than about 75%, and mainly having essentially fully interconnected sheath-like non-spherical pores and essentially non-fibrous walls.

Abstract

The present invention relates to a tunable delay system and corresponding method for delaying a signal. The system includes an oscillator for providing a carrier. A first mixer modulates the signal with the carrier. The modulated signal is delayed in a metamaterial transmission line. Afterwards, a second mixer is used to separate the delayed signal from the carrier. The present invention also relates to using a metamaterial transmission line for delaying a modulated signal.

Abstract

The present invention is concerned with a process for fabricating a buried optical waveguide, comprising providing a multi-layer piece of material having a waveguide core layer, generating a laser beam and producing by ablation at least two trenches by applying the laser beam onto the multi-layer piece of material. The two trenches extend through the multi-layer piece of material including the core layer. Upon the ablation, melted material from the multi-layer piece is produced and the core layer is encapsulated between the two trenches with the melted material to produce the buried optical waveguide in the multi-layer piece of material. The present invention also relates to a buried optical waveguide comprising a multi¬ layer piece of material having a waveguide core layer, at least two trenches laser ablated through the multi-layer piece of material including the core layer and encapsulating material having melted from the multi-layer piece upon laser ablation and leaked to cover and therefore encapsulate the core layer in the at least two trenches to thereby form the buried optical waveguide.

Abstract

The present invention relates to a novel perfusion bioreactor allowing continuous medium feed and extraction of metabolites or other desired products from cells. The invention is useful for plant cell cultures but may also be used for mammalian cell cultures, insect cell cultures and bacterial cell cultures. The design of the reactor includes sedimentation columns mounted inside the bioreactor to separate single cells and cell aggregates from the culture medium at a very low shear stress. The operating conditions allow a stable cell/medium separation by maintaining the medium upward velocity equal to or slightly lower than the cell sedimentation velocity.
