Dosing and discharging device for flowable media including powder/air dispersions

A dosing device (17) for the medical administration of powder (16) through the nose or mouth has a valve body (27) which is movable in a discharge channel (22) between two valve seats (25, 26). During suction, the spherical valve body (27) is raised from the lower, container-sealing valve seat (26) and moved by a flow drag to the upper valve seat (25), so that it closes the discharge channel (22) and terminates dosing. The formation of the air / powder dispersion can be assisted in that the air subsequently sucked into the container is directed onto or into a powder supply or to a powder receiver in a pre-chamber fillable by tilting the device for pre-dosing.

Dynamic switching between edge nodes in autonomous network system

System and method of dynamically selecting an egress edge node for data transmission between different autonomous systems based on real-time route performance detection. With respect to a destination node located in a second autonomous system, a plurality of edge nodes in the first autonomous system each operate to detect route performance in real-time and send the detected information to a control center for evaluation. The evaluation results are compared and used to select an optimal edge node and an associated link for transporting data between the source node and the destination node. To switch from a first edge node to a second one, the IP address of the source node contained in the data packets are converted from an address assigned to the first edge node to an address assigned to the second edge node.

Enhanced antiviral activity against foot and mouth disease

Previously, we showed that type I interferon (alpha / beta interferon [IFN-α / β]) can inhibit foot-and-mouth disease virus (FMDV) replication in cell culture, and swine inoculated with 109 PFU of human adenovirus type 5 expressing porcine IFN-α (Ad5-pIFN-α) were protected when challenged 1 day later. In this study, we found that type II pIFN (pIFN-γ) also has antiviral activity against FMDV in cell culture and that, in combination with pIFN-α, it has a synergistic antiviral effect. We also observed that while each IFN alone induced a number of IFN-stimulated genes (ISGs), the combination resulted in a synergistic induction of some ISGs. To extend these studies to susceptible animals, we inoculated groups of swine with a control Ad5, 108 PFU of Ad5-pIFN-α, low- or high-dose Ad5-pIFN-γ, or a combination of Ad5-pIFN-α and low- or high-dose Ad5-pIFN-γ and challenged all groups with FMDV 1 day later. The control group and the groups inoculated with either Ad5-pIFN-α or a low dose of Ad5-pIFN-γ developed clinical disease and viremia. However, the group that received the combination of both Ad5-IFNs with the low dose of Ad5-pIFN-γ was completely protected from challenge and had no viremia. Similarly the groups inoculated with the combination of Ad5s with the higher dose of Ad5-pIFN-γ or with only high-dose Ad5-pIFN-γ were protected. The protected animals did not develop antibodies against viral nonstructural (NS) proteins, while all infected animals were NS protein seropositive. No antiviral activity or significant levels of IFNs were detected in the protected groups, but there was an induction of some ISGs. The results indicate that the combination of type I and II IFNs act synergistically to inhibit FMDV replication in vitro and in vivo.

Optimized control method for primary frequency regulation based on exergy storage correction of thermodynamic system of coal-fired unit

An optimized control method for a primary frequency regulation based on an exergy storage correction of a thermodynamic system of a coal-fired unit is provided. Through measuring and recording temperatures and pressures of working fluids and metal heating surfaces of the coal-fired unit thermodynamic system in real-time, an exergy storage amount of the thermodynamic system is obtained. During a transient process, according to an exergy storage variation before and after acting of each regulation scheme, a maximum power output of each scheme is obtained. Thereafter, through comparing the maximum power output with a maximum power regulation quantity required by a current frequency regulation, an optimal primary frequency regulation control scheme is selected, and a primary frequency regulation control logic is corrected, so as to be high-efficiently and accurately involved in the primary frequency regulation control and maintain a fast and stable grid frequency. The present invention improves a predictive accuracy of an actual effect of the various thermodynamic system regulation schemes and reduces a selection blindness of the primary frequency regulation schemes, so that an operation flexibility of the coal-fired power unit during the transient processes is greatly improved.
