Abstract: The present invention discloses a method for preparing ice cream with good storage and transportation stability. The raw materials of the ice cream include small-granule starch. The amount of small-granule starch added is 1% to 6%. By adding small-granule starch to the ice cream, the structure of the ice cream is improved, resulting in ice cream with good storage and transportation stability. It can maintain ideal hardness at high storage and transportation temperatures while retaining good shape, texture, and sensory qualities. This enhances the ice cream product's resistance to temperature fluctuations during cold chain storage and transportation, making it suitable for storage and sales temperatures higher than conventional storage temperatures (?18° C.), thus promoting energy saving and carbon reduction in the ice cream storage and transportation process.

Abstract: The disclosure discloses a stuck staple processing mechanism of an electric stapler and the electric stapler. The stuck staple processing mechanism of the electric stapler includes a driving mechanism, a transmission mechanism, a pop-up staple channel assembly, a controller and a pop-up mechanism. The transmission mechanism is connected with a pop-up switch of the pop-up staple channel assembly through the pop-up mechanism. When the controller controls the driving mechanism to rotate along a staple placing direction, the pop-up mechanism does not make the staple channel assembly act. When the controller controls the driving mechanism to rotate in an opposite direction of staple placing, the transmission mechanism makes the pop-up switch act through the pop-up mechanism to pop up a staple channel of the staple channel assembly, so as to facilitate a removal of a stuck staple.

Abstract: Porous metal oxide catalytic materials with planar morphologies which are derived from metal-organic framework (MOF) materials via thermal decomposition, oxidation pretreatment and pyrolysis processes. The porous metal oxides are mainly transition metal oxides, derived from MOFs containing the corresponding transition metal ions, such as Cu, Zn, Y, La, Ce, Ti, Zr, V, Cr, Mn, Fe, Co, and Ni ions. The transformation conditions from MOF materials to metal oxides, such as temperature, atmosphere and duration, are well defined to obtain metal oxides with controlled morphologies. Furthermore, the present subject matter relates to a low-temperature catalytic decomposition of volatile organic compounds (VOCs) with a wide concentration range on two-dimensional metal oxides.

Abstract: The disclosure provides an approach for permission checking in virtualized desktop infrastructure (VDI) redirection so that only a rightful owner can access a smart card device. When a user logs in to a remote desktop via a VDI client, a service to access the smart card device is notified of the log in event and the user's account identifier. The service changes ownership and access permissions of a domain socket file used by processes to communicate with the service so only the user account owns and has permission to access the domain socket. The service may also bind, listen to, and receive requests from the domain socket to check users who have opened the domain socket file. In response, the service may determine processes that have opened the file and associated user accounts, as well as generate warnings and/or terminate processes which are not authorized to access the domain socket.

Abstract: The banknote temporary storage device includes: a pair of coiling tapes, a large coiling block, an upper and lower coiling block assemblies, and a banknote inlet/outlet. Each of the pair of coiling tapes has one end fixed on the large coiling block and another end, and the another ends of the pair of coiling tapes are respectively fixed to the upper coiling block assembly and the lower coiling block assembly. The banknote inlet/outlet includes an upper clamping roller and a lower clamping roller. The large coiling block is provided with a lower passage guide plate having one end rotatably arranged on the lower rotating shaft and a relatively free end, a tail portion of the free end is an arc-shaped portion concentric with the large coiling block, and an angle by which the arc-shaped portion surrounds the large coiling block ranges from 40 degrees to 50 degrees.
