Abstract: In an illustrative embodiment, a heat-not-burn tobacco aerosolization device aerosolizes a high viscosity, wet tobacco product at a very low temperature and reduces harmful and potentially harmful carcinogen (HPHC) emissions by six times or more relative to conventional heat-not-burn products while also providing substantially improved taste and user experience. Embodiments exemplified herein provide a compelling and healthier substitute for cigarette smoking that avoids the HPHC emissions of conventional heat-not-burn products while also avoiding the increased risk of addiction and short-term health effects reported in connection with conventional vaping devices.

Abstract: Chronic obstructive pulmonary disease (COPD), characterized by chronic airflow limitation, is a serious and growing public health concern. The major environmental risk factor for COPD is cigarette smoking, but the biological mechanisms underlying COPD are not well understood. Herein, proton nuclear magnetic resonance (1H-NMR) spectroscopy is used in methods to identify metabolites and biomarkers associated with lung function in COPD.

Abstract: A swing scooter includes a frame, a riser bar, a handlebar, a front wheel, at least two carrier rods, a flexible linking mechanism, at least two rear wheels, at least two pedals, at least two auxiliary wheels and at least two swinging modules. The auxiliary wheels are installed at the rear of the rear wheels. When the front wheel and the rear wheels touch the ground, the auxiliary wheels are situated at an appropriate height from the ground, and the swinging module is coupled between the carrier rods and the rear wheels. During use, the front and rear wheels situated at the general using status touch the ground, or the front of the scooter is tilted, such that the rear wheels and the auxiliary wheels touch the ground to add more fun to the use of the scooter.

Abstract: A recreational vehicle includes two parallel wheels installed at a front wheel set or a rear wheel set, and the axes of the two wheels are not configured to be aligned on the same horizontal line, and the two wheels are installed at a frame through an adjusting module movable with respect to the frame, and a fixing module is installed between the frame and adjusting module for controlling whether to move the adjusting module with respect to the frame. The recreational vehicle is capable of adjusting the width of the rear wheel that touches the ground to enhance the variability, adaptability and practicality of the vehicle.

Abstract: A method and a system for preparing a tobacco extract for use in an electronic smoking device are provided. A tobacco extract and an electronic smoking device are also provided. The method includes grinding tobacco into granulated particles, and heating purified water. The method further includes injecting the heated purified water through the granulated particles of the tobacco for a predetermined period of time to produce an aqueous solution, and adding purified water to the aqueous solution. Further, the method includes heating the aqueous solution, and injecting the heated aqueous solution through ground tobacco for the predetermined period of time to produce a tobacco extract for use in the electronic smoking device.

Abstract: A children's balancing vehicle comprising a front vehicle rack, a handle set, a rear fork, a seat tube and a fastening component. The front vehicle rack has a front fork. A front wheel is assembled below the front fork while a stand pipe is disposed thereon. A vehicle rack body is disposed at a rear of the stand pipe. The handle set is disposed onto the stand pipe. The rear fork has a plastic main body. A rear wheel is disposed below the rear fork. The seat tube passes between the vehicle rack body and the plastic main body of the rear fork. A seat cushion is disposed onto the seat tube. The fastening component passes through the vehicle rack body, the plastic main body of the rear fork and the seat tube so as to mutually assemble and fasten them. Assembly of the children's balancing vehicle can be completed by using simple fastening components.
