Abstract: Devices for and related methods of treating a subject having a neurological injury to prevent or mitigate secondary injury are described. In an example, the devices include a base and a plurality of microneedles protruding from the base, the microneedles including a biocompatible and biodegradable matrix, and a neurologically active ingredient disposed within the matrix. In an example, a portion of the plurality of microneedles is shaped to penetrate the dura when the device is placed in contact with the dura.

Abstract: A barcode reader may include a barcode reading system, a rechargeable battery, and a battery charging system. The battery charging system may be configured so that, in response to detecting placement of the barcode reader in a charging cradle, the battery charging system delays charging the battery if a charge level of the battery is above a first threshold level.

Abstract: The present disclosure generally refers to a transmission comprising a transmission housing and at least one transmission stage arranged in the transmission housing. The transmission stage may include, coaxially with respect to an axis, a sun gear, a planet carrier with at least two planet gears rotatably mounted on the planet carrier; and an internal gear as transmission parts. At least one stop means may be provided for limiting the axial movement of two transmission parts which are movable relative to one another. The stop means may comprise a ball pair with a first ball assigned to a first transmission part and a second ball assigned to a second transmission part. The two balls may be arranged so as to be rotatable about their ball center on the axis.

Abstract: A drive connection is disclosed. The drive connection may be configured to be interconnected between a main driving unit and a main gear unit of a driving device configured to drive a chain of a conveyor of a longwall device. The drive connection may have a housing configured to be connected to the main driving unit and to the main gear unit. The drive connection may also have a drive shaft disposed within the housing and configured to transmit torque from the main driving unit to the main gear unit. In addition, the drive connection may have a chain tensioning apparatus disposed within the housing. The chain tensioning apparatus may have a worm drive interacting with the drive shaft. The chain tensioning apparatus may be configured to drive the drive shaft for tensioning the chain of the conveyor when the main driving unit is in a non-operative state.

Abstract: The present disclosure refers to a drive unit for chain drives in mining. The drive unit may comprise at least one drive motor, a gearing unit coupleable to the drive motor, and a power supply housing provided with flange connections on its right and left sides. The at least one drive motor and the gearing unit both may be configured to be both connectable optionally on the right hand side or left hand side flange connection of the power supply housing. Further, a power supply unit housing supply assemblies for the drive motor and/or the gearing unit may be provided. The power supply unit may be mounted in the power supply housing.

Abstract: Described herein are methods for converting lignocellulosic biomass to ethanol, comprising the step of contacting the lignocellulosic biomass with a mixture for a period of time at an initial temperature and an initial pH, wherein the mixture comprises a first microorganism and a second microorganism, thereby producing an amount of ethanol. The first microorganism or the second microorganism may be a thermophilic or mesophilic microorganism. The first microorganism may be a native cellulolytic microorganism or a native xylanolytic microorganism; and the second microorganism may be a genetically engineered xylanolytic microorganism or a genetically engineered cellulolytic microorganism. The microorganisms may be Clostridium thermocellum or Thermoanaerobacterium saccharolyticum, or any number of a wide variety of others.
