Abstract:
A process for producing a carbonic diester by the catalytic reaction of carbon monoxide with a nitrous ester in the presence of a solid catalyst, characterized by adding a minute amount of a chloroformic ester to the feedstock gas comprising carbon monoxide and a nitrous ester, whereby the catalyst can be kept in a highly activated state for long and can provide the objective diester at a high reaction velocity and a high selectivity stably for long.
Abstract:
An oxide superconductor comprising Ln2BaCuO5 and PtBaCuO with a mean particle diameter of 0.1 to 10 νm finely dispersed in the crystal of LnBa2Cu3Oy, wherein Ln represents at least one rare earth element including Y; and a process for producing the same by melting a powdery raw material comprising composite oxides of Ln, Ba and Cu, rapidly cooling the melt to effect solidification, crushing the solid, adding thereto a Pt powder, molding the mixture, heating the molding into a semi-molten state, and cooling the resulting molding.
Abstract:
An oxide superconductive material of a structure wherein RE2BaCuO5-phase particles of 20 mum or less in diameter are dispersed in an REBa2Cu3O7-y phase (wherein RE represents a rare earth element including Y) is disclosed. This superconductive material is obtained by melting a superconductive oxide composition of RE, Ba and Cu, rapidly quenching and solidifying it to obtain a platy or linear product, heating it to a temperature range of 1000 to 1350°C to make it half-molten, and gradually cooling it at a rate not higher than 200°C.
Abstract:
The invention relates, in part, to a method of selectively treating a patient having breast cancer, comprising administering a therapeutically effective amount of a M-CSF antagonist to the patient on the basis of the patient having a level of CD 163 expression that is predictive that the patient will respond to an M-CSF antagonist. The invention relates, in part, to a method of treating a patient having triple negative breast cancer, comprising administering a therapeutically effective amount of an M-CSF antibody or fragment thereof to the patient, wherein the M-CSF antibody or fragment comprises 1, 2, 3, 4, 5, or 6 CDRs as shown in Table 1. The invention relates, in part, to a method of treating a patient having breast cancer, comprising administering a combination of a therapeutically effective amount of an M-CSF antagonist, a therapeutically effective amount of a second agent and a therapeutically effective amount of a third agent.
Abstract:
A novel polyimide wherein a tetracarboxylic dianhydride comprising 3,3',4,4'-biphenyltetracarboxylic dianhydride as the essential component is the starting tetracarboxylic dianhydride component, and an amine comprising between 0.5 and 30 mole percent of a diamine represented by the following general formula is the starting diamine component. (wherein A is a direct bond or a crosslinking group, and R1-R4 each represent a substituent). It is possible to obtain a polyimide, a polyimide film and a laminated body with an improved adhesion property and an improved moisture permeation rate, even without surface treatment, comprising, as the essential tetracarboxylic dianhydride, 3,3',4,4'-biphenyltetracarboxylic dianhydride which has conventionally only yielded polyimides with low adhesive strength.

Abstract:
A method of making an oxide superconductor comprising the steps of putting a powdery material to be molded into an oxide superconductor on silver or silver oxide in a pan, heating said pan to a temperature higher than the melting point of silver so as to bring said material into a half-melting state while said material is floating in said molten silver, and cooling said pan and taking out said material from re-solidified silver, whereby a bulky material 10 cm or more in diameter free of cracks can be obtained.
