A near infrared phosphorescent organometallic complex includes a cyclometalating ligand and a transition metal. The cyclometalating ligand includes a fused aromatic ring structure with carbon atoms, and a heteronuclear aromatic ring with a nitrogen atom. The transition metal is bonded to the nitrogen atom in the heteronuclear aromatic ring and one of the carbon atoms in the fused aromatic ring structure. The heteronuclear ring can be part of the fused aromatic ring. The organometallic complex is capable of phosphorescent emission with maximum emission intensity occurring at a wavelength in a range from about 650 nm to about 2000 nm.

An exemplary support stand (102) for a flat-panel display body includes an elevating support (30), a monitor bracket (50), and a support member (20). The elevating support includes a first chassis (321), a second chassis (322), a plurality of supporting blocks (3231) for connecting end portions of the first chassis and the second chassis, an elastic member (391), a first pivot subassembly (305), and a second pivot subassembly (306). The monitor bracket is rotatably connected to the first pivot subassembly. The support member is rotatably connected to the second pivot subassembly. The elastic member is capable of exerting a rebound force on two of the first chassis, the second chassis, and the supporting blocks. The first and second pivot subassemblies are fixed to the supporting blocks. The monitor bracket and the support member are rotatably connected to the first and second pivot subassembly correspondingly.

A configuration system uses process plant items that may represent, or be capable of representing, entities in a process plant to assist in configuring, organizing, and changing the control and display activities within the process plant. Access to the items may be controlled by associating access control data with the items. The configuration system may also use objects that represent, or may be capable of representing, one or more steps to be performed by entities in the process plant. Access to these objects may be controlled by associating access control data with the objects. The access control data may indicate whether users or certain users may be able to, for example, view or modify all or some data associated with the process plant items or the objects. The process plant items may comprise, for example, module class objects which may be capable of generically representing process entities of the process plant, module objects which may be capable of specifically representing process entities of the process plant, composite templates, module templates, etc. The objects that represent, or may be capable of representing, one or more steps to be performed by entities in the process plant may comprise, for example, phase classes or unit phases.

An objective of the present invention is to provide an anti-graying agent. The present invention provides a method for screening an anti-graying agent whereby a substance that increases expression of AFF-4 in cells is selected by applying a candidate substance to cells in vitro; and, an anti-graying agent containing at least one type of herbal extract selected from the group consisting of Ganoderma lucidum (Fr.) Karst. extract, Panax schinseng Nees extract, Oryza sativa (Rice) Bran extract and Rabdosia japonicus extract selected with this method in an amount effective for increasing expression of AFF-4.
摘要:
A platinum (II) complex of the general formula (I) or (II), in which Ar1, Ar2, and Ar3 are each independently aryl, heteroaryl, or heterocyclic. Ar1, Ar2, and Ar3 together form a tridentate ligand coordinated to the platinum through atoms X, Y, and Z, respectively, and X, Y, and Z are independently carbon or nitrogen. V is a bridging group or a covalent bond, and W is an anion. In general formula (I) in some cases, Ar1 is an anion and Ar2 and Ar3 are neutral; in other cases, Ar1 and Ar3 are neutral and Ar2 is an anion. In general formula (II), in some cases, Ar3 is an anion and Ar1 and Ar2 are neutral; in other cases, Ar1 and Ar3 are neutral and Ar2 is an anion. The complexes are asymmetric. The complexes emit in the UV to near IR range and are useful as emitters for organic light emitting devices.

A method for a network device to access a packet switched network is applied to a system in which the network device accesses the packet switched network by connecting to PEs in an active-standby mode. The method includes: an active PE and a standby PE each sends a fault detection message to the network device through an interface connected to the network device; the active PE sets the state of the interface to “up” and advertises a route to a remote PE if a fault detection response returned by the network device is received through the interface within a preset period; otherwise, the active PE sets the state of the interface to “down”, and withdraws the advertised route; and the standby PE sets the state of the interface to “up” and advertises another route to the remote PE after receiving a fault detection response through the interface connected to the network device.
摘要:
A version control system helps to keep track of versions of process plant items that may represent, or be capable of representing, entities in a process plant. The process plant items may comprise, for example, module objects which may be capable of specifically representing process entities of the process plant. These module objects may be created from module class objects which may be capable of generically representing process entities of the process plant. Version data is stored and associated with a module object. The version data may comprise data indicative of a version of a module class object that was used to create the module object. The version data may also comprise data indicative of a version of the module object. Configuration systems, version control systems, viewing systems, debugging systems, run-time monitoring systems, asset management systems, etc., may examine or permit viewing of the version control data associated with an item.
