Abstract: The present invention relates to a molecular marker, a specific primer pair, and an identification method of the high-quality Ganoderma lucidum strain HMGIM-M624. The high-quality Ganoderma lucidum strain HMGIM-M624 was preserved in Guangdong Microbial Culture Collection Center (address: 5th Floor, No. 59 Building of No. 100 Yard, Mid. Xianlie Road, Guangzhou City) with the preservation number of GDMCC No: 60889 on Nov. 7, 2019. The molecular marker is an InDel molecular marker. The high-quality Ganoderma lucidum strain HMGIM-M624 has a base deletion of CATGCTGTA at the 246451th-246460th site of the chromosome sca34. The present invention provides reagents for detecting the molecular marker of the high-quality Ganoderma lucidum strain HMGIM-M624. The reagents can distinguish the high-quality Ganoderma lucidum strain HMGIM-M624 from the other 11 G. lucidum strains for commercial cultivation, thus specifically identifying the high-quality Ganoderma lucidum strain HMGIM-M624.

Abstract: Turbocharger systems and related methods and devices are provided for determining rotational speed of a turbocharger. A speed sensing device is mounted to a turbocharger and includes an acceleration sensing arrangement and an acoustic sensing arrangement. The speed sensing device outputs an acceleration-based speed value as the current turbo speed when the acceleration-based speed is stable, and otherwise outputs an acoustic-based speed value to as the current turbo speed if the acoustic-based speed value stable or outputs an estimated value as the current turbo speed when both of the acceleration-based and acoustic-based speeds are unstable. In exemplary embodiments, the acceleration sensing arrangement and the acoustic sensing arrangement are provided on a common substrate.

Abstract: A demountable showerhead with tearing mode has backstop mouths arranged on an outlet surface of a shower. Each backstop mouth is disposed with an outlet waterway to connect to the waterway of the shower. The outlet waterway has a big and small end, and is contracted along the outlet direction of the shower, and a flexible cover, which comprise bowl shape plugs and a flexible connector connected to the bowl shape plugs; each plug has a big and small end, the small end of the plug is connected to the connector, the big end of the bowl shape plug is deformed and plugged into the small end of the backstop mouth, the external wall of the plug is coupled to the outlet waterway in elastic way; the internal wall of the plug is contracted along the outlet direction, the bottom of the external wall is disposed with outlet holes.
