Abstract: The present disclosure relates to a complex probiotic composition and a method for improving exercise performance of a subject with low intrinsic aerobic exercise capacity. The complex probiotic composition, which includes Lactobacillus rhamnosus GKLC1, Bifidobacterium lactis GKK24 and Clostridium butyricum GKB7, administered to the subject with the low intrinsic aerobic exercise capacity in a continuation period, can effectively reduce serum lactic acid and serum urea nitrogen after aerobic exercise, reduce proportion of offal fat and/or increase liver and muscle glycogen contents, thereby being as an effective ingredient for preparation of various compositions.

Abstract: The present disclosure belongs to the technical field of lithium battery cathode materials, and discloses a preparation method of multiple carbon-coated high-compaction lithium iron manganese phosphate, comprising the following steps: (1) synthesizing a carbon and vanadium co-doped ferromanganese phosphate precursor through a co-precipitation method, sintering, and removing crystal water to obtain an anhydrous ferromanganese phosphate precursor; (2) adding lithium phosphate, a supplemental phosphorus source, an organic carbon source, a dopant and deionized water, and performing ball milling, wet sanding, spray drying and sintering to obtain an intermediate material; and (3) adding deionized water and the organic carbon source, then performing ball milling, sanding, spray drying, sintering and air jet pulverization to obtain multiple carbon-coated high-compaction lithium iron manganese phosphate.

Abstract: A heat dissipation assembly includes a base, two heat pipes, a first heat sink, and a fan. The first heat sink includes a first fin assembly installed to one of the heat pipe, and a second fin assembly installed to the other heat pipe. The fan is installed to the first fin assembly opposite to the second fin assembly. The first fin assembly includes a plurality of first fins spaced from and parallel to one another. The second fin assembly includes a plurality of second fins spaced from and parallel to one another. The first fins are misaligned with the second fins. Each heat pipe is mounted to the base, and extends through the first or second fins.

Abstract: Embodiments of the present invention disclose a fuel cell control method. The method includes: obtaining a current output power of a fuel cell; obtaining a current inlet-outlet temperature difference of a fuel cell stack, where the current inlet-outlet temperature difference of the stack is a difference between a stack temperature and an ambient temperature; controlling a hydrogen exhaust solenoid valve according to the output power and working parameters of the hydrogen exhaust solenoid valve corresponding to the output power; and controlling the stack temperature according to the output power and the current inlet-outlet temperature difference of the stack, so that the amount of water generated in the fuel cell is equal to the amount of water discharged. In the embodiments, the fuel cell can work in a preferred state, steady output of the cell is ensured, and the service life is improved.

Abstract: A toner cartridge including a container body having a discharge opening. A drive transmitting member is fixedly coupled with the container body near the discharge opening. The drive transmitting member is sized and shaped to transmit rotational movement to the container body. A collar is moveably coupled along the container body, and the collar closes the discharge opening in a first position, and opens the discharge opening in a second position. The cartridge further includes, in one example, a biasing element sized and shaped to bias the collar toward the first position. In another example, the drive transmitting member includes at least one deflectable support member, and the deflectable support member includes a ramped drive element. The ramped drive element includes a first ramp face, a second ramp face, and at least one driving face. Optionally, the first and second ramp faces are sloped with respect to the support member.
