ANALYSIS OF THE PRESSURE DISTRIBUTION PATTERN AND THE CONTROLLING BALANCE DURING KICK MOVEMENT OF TAI-CHI CHUAN
Full text linkThe purpose of this study was to compare the pressure distribution patterns of the stable kick and unstable kick from the kick movement of a Tai-Chi Chuan athlete. A national elite female Tai-Chi Chuan athlete was the subject for this study. The Tekscan HR Mat Pressure Measurement System was used to collect the vertical ground reaction force and the pressure history of the standing foot in right kicking movement and left kicking movement. All the data of the standing foot were divided into metatarsals, tarsals and phalanges to calculate the partial force and partial pressure. The pressure-time diagram of the phalanges, metatarsals and tarsals indicated that the pressure histories trended to be stable in each time as the lefl kick completed, and the phalanges produced \u27snatchy\u27 and larger pressures acting on the ground
Three-component velocity measurements in a momentum-conserving, axisymmetric, turbulent jet
No full textExperiments have been performed on a momentum conserving axisymmetric turbulent jet, the turbulence characteristics of which are well known [1]. Simultaneous three-component velocity measurements are acquired with high spatial and temporal resolution, using a new triple-sensor hotwire probe. Velocity and directional calibrations are performed using a dedicated automatic calibration system. Two experiments are performed; one for capturing the average velocity field in a 3D volume, and one for investigating the turbulence spectra in specific points in space. In the first experiment, measurements are performed in 9 equidistant cross-planes, from 10- to 50-diameters downstream of the nozzle using a computer-controlled traversing system. The spatial resolution is as low as 1 mm and the sampling rate was 10 kHz. In the second experiment, long velocity time histories are acquired with 50 kHz sampling rate to perform power spectral density computations for each velocity component. Preliminary results of velocity capture confirm the general characteristics of the turbulent jet. The power spectra at different positions indicate that the turbulent fluctuations are not isotropic at lower frequencies
A General History of the Congregation of the Mission Beginning after the Death of Blessed Vincent de Paul
Full text linkThis work is the earliest known history of the Congregation of the Mission and dates from about 1730. Vincentian historian John E. Rybolt, C.M., building on the initiative of Stafford Poole, C.M., completed this English translation from the original French. The author, Claude-Joseph Lacour, C.M. (1672-1731), drew from already published materials and his own recollections. While the story he tells may seem familiar, Lacour included materials that are unknown anywhere else and delivers a first-hand account of the Congregation’s rapid growth in those early days. The text is essential reading for anyone wishing to better understand Vincent de Paul’s society of apostolic life of priests and brothers following his death.https://via.library.depaul.edu/vincentian_ebooks/1044/thumbnail.jp
Positive Engagement with Communities through Taiji: Case Study of a One Day Experiential Workshop
No full textWhilst the physical health benefits of taiji have been reported, there is limited information on the influences of taiji on mental health. This paper reports on a collaborative one day experiential workshop between a university, a local martial arts academy and Mental Health in Higher Education (MHHE). The purpose of the day was to explore the impact of taiji on people’s mental health and well-being. The workshop used a multi method approach to explore the potential benefits of taiji. Participants, who were service users and various professionals, were introduced to the philosophies behind taiji and gained an understanding of the concept of qi. This was followed by participants being guided through a practical taiji session to demonstrate how qi can be activated. The remainder of the day was used to deconstruct poetry and narratives to trigger discussions on the range of benefits of taiji. Those participating acknowledged the social benefits of belonging to a community of taiji practitioners. Two pragmatic issues were also highlighted: cultural background being an important influence regarding the understanding and practice of taiji; and that difficulties in gaining access to reputable and qualified teachers can act as a barrier to integrating taiji within educational programmes
Turbulent separation in lower curved wall channels
No full textTurbulent boundary layer separation in channels with a lower curved wall is studied using direct numerical simulations (DNS). Turbulence dynamics are studied through classical statistical tools such as the turbulent kinetic energy budget for varying lower curved wall dimensions. The geometry features are expected to have a significant effect on the fluid flow structures and the characteristic scales of separation. The separation bubble behind the bump is studied in terms of its size, turbulent kinetic energy production mechanisms and transfer and scale-by-scale energy budget. New innovative data-analysis techniques will be used based on the generalisation of the Kolmogorov equation to anisotropic and spatially non-homogeneous flow configurations
Turbulence modulation in particle laden homogeneous shear flow: Exact Regularized Point Particle method
No full textThis contribution presents a first evaluation of a new approach, dubbed the Exact Regularized Point Particle (ERPP) method [Gualtieri et al., Exact regularized point particle method for multi-phase flows in the two-way coupling regime, arXiv preprint arXiv:1405.6969], designed to model the modulation of turbulence by hundred thousands of small inertial particles. The approach overcomes some intrinsic difficulties which arise in some circumstances in available approaches like, e.g., the Particle In Cell (PIC) method introduced by Crowe and coworkers since 1977. Numerical results concerning a homogeneous shear flow at moderate values of the Reynolds number laden with hundred thousand of small inertial particles are discussed documenting the turbulence modification in the so-called two-way coupling regime, in a range of control parameters unaccessible to the available approaches
The great household in late medieval England
No full textIn the later medieval centuries, a whole range of important social, political, and artistic activities took place against the backdrop of the great English households. In this lively book, C. M. Woolgar explores the fascinating details of life in a great house. Based on extensive investigation of household accounts and related primary documents, Woolgar vividly illuminates the operations of great households. He also delineates the major changes that transformed the economy and geography of both lay and clerical households between 1200 and 1500.In this portrait of aristocratic and gentry life in medieval England, Woolgar describes the roles of family members, the situations of servants, the uses of space within the household, food and drink for daily consumption and for special occasions, furnishing, clothing, arrangements for travel, household animals, cleanliness and hygiene, entertainment, the practices of religion, and intellectual life. The author also analyzes the qualitative and social evolution of great households as definitions of magnificence and conventions of etiquette became increasingly elaborate
