Abstract: One aspect of the present disclosure pertains to a connector for conveying a suspension of particles through a system, comprising: a housing (10) comprising an internal cavity (12) and a first passageway (14) for conveying fluid; two or more inlet conduits (16a, 16b, 16c, 16d) formed in the housing and arranged radially with respect to a longitudinal axis of the first passageway; and a rotatable component (18) received in the internal cavity of the housing and rotatable about the longitudinal axis of the first passageway such that a continuous flow path can be established between the first passageway and a selected inlet conduit; wherein an angle between each of the inlet conduits and the first passageway (22) is greater than 90 degrees. Other aspects pertain to systems that employ such a connector and to methods of using such systems.

Abstract: A flexible brachytherapy device includes a bioresorbable carrier matrix structure comprising a plurality of radio-isotope particles and having opposite first and second surfaces. The bioresorbable carrier matrix structure degrades, when implanted at a wound site, at a rate such that the bioresorbable carrier matrix structure has a half-life that is longer than a half-life of the plurality of radio-isotope particles. A hydrophilic substrate located adjacent to the first surface of the bioresorbable carrier matrix structure degrades, when implanted at the wound site, at a rate faster than the bioresorbable carrier matrix structure. A hydrogel substrate located adjacent to the second surface of the bioresorbable carrier matrix structure shields radioactivity and degrades at a rate such that the hydrogel substrate has a half-life that is longer than the half-life of the plurality of radio-isotope particles.

Abstract: A flexible brachytherapy device includes a bioresorbable carrier matrix structure comprising a plurality of radio-isotope particles and having opposite first surface and second surfaces. The bioresorbable carrier matrix structure degrades, when implanted at a wound site, at a rate substantially longer than a half-life of the plurality of radio-isotope particles. A hydrophilic substrate located adjacent to the first surface of the bioresorbable carrier matrix structure degrades, when implanted at the wound site, at a rate shorter than the bioresorbable carrier matrix structure to prevent migration of the device during the half-life of the plurality of radio-isotope particles. A hydrogel substrate located adjacent to the second surface of the bioresorbable carrier matrix structure shields radioactivity and degrades at a rate longer than the half-life of the plurality of radio-isotope particles.

Abstract: A single burner snow melter is capable of a snow start. The burner assembly has a fuel burner having adjustable combustion output and a nozzle through which products of combustion emerge, and a combustion chamber which has a first portion in substantially air-tight communication with the fuel burner and which encloses the nozzle. A second portion of the combustion chamber is shaped and dimensioned such that the second portion is placed into a snow melting receptacle or pit. The combustion chamber has a plurality of directional discharge means formed at least on its second portion through which products of combustion from the fuel burner emerge, and thus agitate, and melt snow loaded into a tank or pit. The burner assembly also includes an air cooling assembly for supplying air to cool at least the first portion of the combustion chamber.
