摘要:
The invention provides compositions and methods for inhibiting Chk1 and/or Chk2 kinases. Also provided are compositions and methods for inhibiting G2 cell arrest checkpoint, particularly in mammalian, e.g., human, cells. The compositions and methods of the invention are also used to treat disorders of cell growth, such as cancer. In particular, the invention provides methods for selectively sensitizing G1 checkpoint impaired cancer cells to DNA damaging agents and treatments. Also provided are methods for screening for compounds able to interact with, e.g., inhibit, enzymes involved in the G2 cell cycle arrest checkpoint, such as Chk1 and/or Chk2/Cds1 kinase.

A method for producing a carbon nanocomposite metal material with increased carbon nanomaterial dispersibility and increased binding between carbon nanomaterial and matrix metal stock is disclosed. A preform obtained by mixing a matrix metal stock and microparticulate-coated carbon nanomaterial without the need for a dispersant and then compacting the material is maintained for a set time period at a temperature that is at or above the melting point of the matrix metal stock. In this state, the heat-treated body is reduced to a temperature that allows hot working, and a compacting treatment is performed.
摘要:
A screw injecting apparatus includes a check valve mounted on the tip end portion of a screw and adapted to be opened and closed in response to rotation of the screw, and a control for controlling operation of the screw such that in a metering phase of molding process, the screw rotates in one direction to feed a melt of molding material toward the nozzle while the check valve is in an open state, when a metered amount of melt is accumulated forward of the tip end portion, the screw moves backward by a predetermined distance to reduce a reaction from the melt accumulated around the tip end portion, thereafter, the screw rotates in the reverse direction to close the check valve and cause the screw to advance until the amount of forward movement of the screw becomes substantially equal to the predetermined distance of backward movement achieved previously.
摘要:
A technique for using an iron plating for coating an aluminum product that results in adequate durability. An aluminum piston (10) used as a plated aluminum product is covered by an iron-based composite plating layer (11). The iron-based composite plating layer (11) contains a carbon nanomaterial, which is applied to the aluminum-based base material using a iron-based composite plating bath formed by mixing a carbon nanomaterial into an iron plating bath.
摘要:
A method for kneading a carbon nanomaterial with a metal material and manufacturing a composite-metal-forming material. A semi-molten metal material obtained by heating the metal material to a temperature of a region where a solid and a liquid are both present is kneaded with the carbon nanomaterial, and the composite metal material is obtained. The composite metal material is heated to the solution temperature of the metal material, and a solution treatment is performed, whereby the composite-metal-forming material is obtained.
摘要:
A composite material composed of nanocarbon materials and metallic materials for a matrix is extrusion molded to have the nanocarbon materials oriented in one direction.
摘要:
A low melting point metal material is made to a thixotropic state in which liquid phases and solid phases coexists. In the thixotropic state of the low melting point metal material, a carbon nano material is kneaded with the low melting point metal material and forms a composite material. Thus obtained composite material is supplied to a metal molding machine and injected into a mold in a thixotropic state or a completely molten state of the metal so that the composite material fills the mold, thereby the composite material is molded to a composite metal product. With the above process, it is possible to injection mold the composite metal product to which the characteristics of the carbon nano material are applied.
摘要:
To eliminate a temperature overshoot or an undershoot during thermocontrol of thermocontrolled components, e.g. an injection cylinder, with resepct to an object temperature in each operating status of the injection molding machine, the Fuzzy Control theory is used for controlling the injection molding machine. By using the Fuzzy Control system, the object temperature of the thermocontrolled components can be attained with practically eliminated overshoot and undershoot.
