There are many legal measures to protect Chinese Medicine Brands,among which the copyright protection is most challenging.The modern copyright system which based on individuality is not in conformity with the traditional Chinese brands which are the products of thoughts.This makes the protection of these brands a difficult task.However,these Chinese medicine brands,as the creation of human intelligence,fit the basic features of copyright object,and the theory of the collective subject provides new hope for the copyright protection of traditional Chinese culture as the medicine brands.
This paper presented results of an attempt to carry out a comprehensive assessment of public recreational space in an urban park, the Quyuan Park in Hangzhou city, China, from the psychological and behavioral aspects.Survey was done on the unit space to get the physical character, and enquiry was done to the users of the unit spaces.The enquiry was composed of an item of users' cognitive assessment in terms of psychological aspect, and an item of users' activity pattern in terms of carrying-out aspect.The following results were gained from the research: 1) Overall, the form of the unit space making up the parks existing in the urban area was found to be a user-oriented type, and its availability became an important assessment factor with this reflected.2).It was found that the recreational value of the forest was low in comparison with that of the unit space of the facilities, the free open space and the waterfront of open space.3).Arbors developed in the woodland, whose assessed value was relatively low, but the feelings of luxuriant forest whose forest floor was arranged and arbors were developed enhanced its value, and the tall herbaceous-forest preventing users from using the forest degraded its value remarkably.4) The important task in the free open space included the setting of space size and topographic slant, the introduction of ground-cover vegetation and its maintenance.5) The important task in the waterfront space included water behavior, embankment form and its material.6) The important task in the forest included the planting design and management techniques relating to the composition of vegetation, such as the height and stand density of arbors, and cover type.7) The unit space of the facilities becomes the secondary existence supporting the open space in the unit space.8) Because the form of use was restricted according to the character of facilities regardless of the physical character in the selection of facilities, consideration of its usability become the important task.
Horse racing is a traditional folk sport culture formed in the special geographical environment, living area and religious belief. Horse Racing made nomadic sonorous and powerful, the formation of moral value orientation of advocating bravery and fair competition. This thesis based on Tibetan historical documents on the origin, development and evolution of the ancient Horse Racing in Tibet. Tibetan people are fond and proud of the “Horse Racing Winning the Crown” excerpt from noted Tibetan heroic epic “Gesar” sung by the Tibetan people for thousands of years. Ancient Horse Racing was derived from the prehistoric era of heroic history. In Tubo and Qing Dynasty, with development of politics and economy, Horse Racing integrated with the cultures of the surrounding countries. Horse Racing becomes a unique military, sport and cultural activity. It enriches the folklore content of Tibetan ancient society and people’s interest in life, showing the spiritual and cultural value of “Nationality on Horseback”.
With the development of the aerospace industry, space missions are becoming more complicated and diversified, and there is a demand for antenna mechanisms with a larger physical aperture. In this paper, a planar deployable mechanism is proposed, which can form a flat reflection surface with a small gap between plates. To this end, a novel large-scale two-dimensional deployable nine-grid planar antenna mechanism is designed. First, two antenna folding schemes and four supporting mechanism schemes are proposed. Through comparison analysis, the antenna configuration scheme with the best comprehensive performance is selected. A kinematic model of the deployable mechanism is established, and its kinematic characteristics are analyzed. Then, the correctness of the kinematic model is verified by comparing the analytical and simulation results of the kinematic model. Subsequently, a finite element model of the antenna is developed. Based on the response surface method, the structural parameters of the support rods of the antenna are optimized, and a set of optimized solutions with lightweight and high fundamental frequency characteristics are obtained. Finally, a prototype of the proposed nine-grid planar antenna is fabricated. The feasibility of the deployment principle and the rationality of the designed mechanism are verified by deployment experiments.
A statistical investigation of the operating slip/twinning modes and their interactions at grain scale over a large area, containing ~400 grains, was carried out on rolled Mg sheets during room-temperature compression based on EBSD and slip trace analysis. For 10% strain, the slip mode was dominated by basal slip (89%). All the 363 identified twins were tension twins. The concave-up stress−strain curve indicated a twinning-dominated deformation behavior, which was further confirmed by the large twinned area fraction (41%) after the deformation. Most twin variants (79%) followed the Schmid law. The Luster−Morris parameter (m′) did not correlate well to twin transmission. However, most twin transmissions (82%) exhibited larger normalized m (Schmid factor) and m′ values. Additional slip systems were frequently active in the twin domains while not in the parent, which can be explained by Schmid law. Slip transfer across the twin boundaries was also observed. Statistical m analysis revealed that twinning activity was closely related to prismatic slip.
All organisms depend on food digestion for survival, yet the brain-gut signaling mechanisms that regulate this process are not fully understood. Here, using an established C. elegans digestion model, we uncover a pathway in which neuronal ROS (free radicals) signal the intestine to suppress digestion. Genetic screening reveals that reducing genes responsible for maintaining ROS balance increases free radicals and decreases digestion. PRDX-2 knockout in olfactory neurons (AWC) elevates ROS and reduces digestive capacity, mediated by the neuropeptide NLP-1 and activation of the mitochondrial unfolded protein response (UPRmt) in the intestine. Additionally, over-expressing nlp-1 or ablating AWC neurons both trigger UPRmt and inhibit digestion. These findings reveal a brain-gut connection in which neuronal PRDX-2-mediated ROS signaling modulates food digestion, highlighting a critical role of free radicals in shutting down digestion to alleviate stress and reduce food consumption. Neuronal PRDX-2-mediated reactive oxygen species (ROS) signaling in C. elegans AWC neurons triggers intestinal mitochondrial stress response, halting digestion to reduce cellular stress. This discovery reveals a brain-gut pathway regulating food intake via ROS signaling.
