We proposed and fabricated multiscale transparent arteriole and capillary vessel models with circular cross sections of 10-500 μm using photolithography. The circularities of the fabricated 10, 50, and 500 μm diameter microchannels were 84.0%, 61.5%, and 82.3%, respectively. Next, we connected these different models to realize a circulation type blood vessel model simulating arteriole networks. We proposed a novel connection method using an intermediate connector made of wax, which we used to connect these models to make a circulation model. In flow experiments, the fabricated models showed no leakage and circulation models with seamless connections were achieved. 相似文献

The paper offers a historical perspective on the linguistic and cultural imperialism embedded in the struggle to maintain French as a leading international language. France was the nation-state where the ideology of national language was first clearly formulated and directly extended to overseas colonies. This shows the close relationship between linguistic nationalism and imperialism. It was believed that French was the language of universal human reason and had the power to civilize people who spoke it. This myth of the "clarté française" and the "mission civilisatrice" had a strong influence on various kinds of metalinguistic discourses that created the taken-for-granted representation of French as dominant language. It is the essential strategy of language dominance to establish the hierarchy of languages as if it were natural order of things. When French was obliged to yield the status of international language to English, there emerged the ideology of "Francophonie" which tried to defend its privilege against the monopoly of English, but the same ideology is also directed against minorities' claims for their own linguistic human right. It could be said that these discourses form a recursive prototype of language dominance whose variations are to be found in other shapes almost all over the world. 相似文献

Public library systems intersect with both public and private spheres of social life, but how they negotiate public legitimacy and private influence remains a mystery. To better understand this problem, this study adopts a communication system approach. Using qualitative content analysis, this study examines data from three US public library systems. This study analyzes how private actors communicate with and through public library systems by parsing the signals into components: transmitter, receiver, medium, and message. The resulting signals form two dimensions: the Public Sphere dimension, where private actors govern, legitimate, and use the library, and the Private Sphere dimension, where private actors exchange personal services and exert economic power. A view of public and private signals in interaction reveals how public legitimacy is threatened and how public library systems can mitigate these threats. This study reveals how public/private conflicts in public libraries arise and how they might be resolved. 相似文献

We previously demonstrated the relationship between sidestepping performance and the preparatory state of ground reaction forces (GRFs). The present study investigated the effect of the preparatory state of GRFs on defensive performance in 1-on-1 subphase of basketball. Ten basketball players participated in 1-on-1 dribble game of basketball. The outcomes (penetrating and guarding) and the preparatory state of GRFs (non-weighted and weighted states, i.e. vertical GRFs below and above 120% of body weight, respectively) were assessed by separating the phases. In the non-weighted state and the weighted state to determine the outcome, the probability of successful guarding was 78.8% and 29.6%, respectively. The non-weighted state prevented delay of the defensive step in the determination phase. Both the non-weighted and weighted states, immediately before the determination phase, were likely to change to the weighted state in the determination phase; during this time, the defender's preparatory state would be destabilised, presumably by the dribbler's movement. These results revealed that the preparatory GRFs before the defensive step help to explain the outcome of the 1-on-1 subphase, and suggest a better way to prevent delaying initiation of the defensive step and thereby to guard more effectively against a dribbler. 相似文献

ABSTRACTThe objective of this research is to elucidate changes in strategy, organization, and operations in the field of public library management. It uses research methods based on detailed case analysis. This research focuses on cases involving U.S. public libraries and the Tokyo Metropolitan Library in Japan from the 1960s to the 2010s. It analyzes documents related to strategic management, organization, and operations collected through surveys and interviews with library directors and managers. This research illustrates (1) 11 core operations of public libraries, (2) transitions of basic organizational structures, (3) elements that cause differences between the U.S. and Japanese public libraries, and (4) primary elements that have impacts on public library management. 相似文献

This study examines the hand and foot reaction force recorded independently while performing the kick-start technique. Eleven male competitive swimmers performed three trials for the kick-start with maximum effort. Three force platforms (main block, backplate and handgrip) were used to measure reaction forces during starting motion. Force impulses from the hands, front foot and rearfoot were calculated via time integration. During the kick-start, the vertical impulse from the front foot was significantly higher than that from the rearfoot and the horizontal impulse from the rearfoot was significantly higher than that from the front foot. The force impulse from the front foot was dominant for generating vertical take-off velocity and the force impulse from the rearfoot was dominant for horizontal take-off velocity. The kick-start’s shorter block time in comparison to prior measurements of the grab start was explained by the development of horizontal reaction force from the hands and the rearfoot at the beginning of the starting motion. 相似文献
