Abstract: An additive printing device and a method for using the same to manufacture a tower structure of a wind turbine is provided. The additive printing device includes a vertical support structure, a support ring suspended from the vertical support structure, and a printer head movably coupled to the support ring for selectively depositing cementitious material. A drive mechanism, such as a rack and pinion, moves the printer head around the support ring while selectively depositing cementitious material. The vertical support structure may be raised and/or the relative position between the vertical support structure and the printer head may be adjusted to raise the printer head to print subsequent layers. This process may be repeated to print the tower structure layer-by-layer from the ground up.

Abstract: A system and method are provided for manufacturing a tower structure. Accordingly, one or more layers of a wall element are deposited with a printhead assembly. At least one recess is defined in the wall element. The recess(es) has a single, circumferential opening positioned along an inner reference curve or an outer reference curve of the wall element. The recess(es) also has a depth which extends in a radial direction and intersects a midline reference curve. A reinforcing element is placed entirely within the recess(es) at the midline reference curve.

Abstract: An electric grill comprises a heating platform, side walls, and grill bars spaced above the heating platform, together defining a heating chamber. The heating platform is heated electrically. A first air supply delivers pressurised air evenly across the heating platform from a central location. A second air supply directs airflow along the side walls to create a vortex of air flowing around the first air supply. The forced airflow provides for fuller combustion of fats and oils from foodstuffs being cooked so that no fat tray is required.

Abstract: A vacuum collector assembly comprises a mountable hitch having support posts connected to one another by horizontal supports and a hinge mechanism for connecting to a trailing carriage. The trailing carriage includes a lift assembly and an engine support frame for mounting thereon an engine operating conjunctively with an impeller assembly for developing negative pressure within a blower housing that is connected in between a receptacle hood and a lawn cutting deck. The engine support frame generally extends outwardly from a pair of vertical columns each having ends connected to support runners for situating atop thereof a pair of receptacles holders suited for receiving receptacle bins utilized in storing collected debris.

Abstract: Stopper rod having an elongate body with an inlet at an upper first end and an outlet at a lower second end. The second end of the body defines a nose for insertion into a tundish outlet. A continuous axial bore extends through the body from the inlet in the first end to the outlet in the second end. A restrictor having an inlet, an outlet and a passageway therebetween is positioned in the axial bore such that the inlet of the restrictor is closer to the first end than the second end. A gas supply conduit is arranged to supply gas into the axial bore above the inlet of the restrictor.

Abstract: An optical fiber device includes a first optical element for transmitting light. An output fiber includes an output fiber core having a light receiving end optically aligned to receive light from the first optical element, and includes at least a first outer cladding on a clad portion. The output fiber includes a mode stripper adhesive with a first adhesive composition and a structural adhesive with a second adhesive composition thereon. The mode stripper adhesive is positioned closer to the first optical element than the structural adhesive to strip a majority of power of cladding guided mode(s) light before reaching the structural adhesive. The mode stripper adhesive has a lower hardness as compared to the structural adhesive, and is substantially indexed matched to an outermost layer of the output fiber that it is in direct contact with.

Abstract: Methods for reducing or preventing the effects of cytotoxic compounds in healthy cells are provided. The methods relate to the use of selective cyclin-dependent kinase (CDK) 4/6 inhibitors to induce transient quiescence in CDK4/6 dependent cells, such as hematopoietic stem cells and/or hematopoietic progenitor cells. Also described is a method of selecting compounds for reducing or preventing the effects of cytotoxic agents compounds in healthy cells.

Abstract: Oil-water dispersions and emulsions derived from petroleum industry operations are demulsified and clarified using anionic polymers. Formation of such oil-water dispersion and emulsions is inhibited and mitigated using the anionic polymers. The anionic polymers comprise: A) 2-80% by weight of at least one C3-C8 ?,?-ethylenically unsaturated carboxylic acid monomer; B) 15-80% by weight of at least one nonionic, copolymerizable ?,?-ethylenically unsaturated monomer; C) 1-50% by weight of one or more of the following monomers: C1) at least one nonionic vinyl surfactant ester; or C2) at least one nonionic, copolymerizable ?,?-ethylenically unsaturated monomer having longer polymer chains than monomer B), or C3) at least one nonionic urethane monomer; and, optionally, D) 0-5% by weight of at least one crosslinker.

Abstract: LKB1 mutation status and/or expression, YES expression and phosphorylation level; and/or CD24 expression are employed to predict melanoma prognosis and response to therapeutics. Inhibitors (including targeted inhibitors) of SRC family kinases (especially YES) are employed to treat melanoma.

Abstract: A packaged fused-fiber device includes a fused-fiber device having at least one input fiber and at least one output fiber, and a fused portion between the input fiber and output fiber. A concave shaped substrate has an inside surface and an outside surface, wherein a minimum distance from the inside surface to the outside surface that is generally set by the substrate thickness is substantially constant throughout the substrate. An affixment material secures the first and second ends of the fused portion to the inside surface of the substrate. A thermally conductive housing is in thermal contact with the outside surface of the substrate. In one embodiment the substrate has an L-shaped cross section and the housing is a hollow housing that has a rectangular cross section.
