Is it possible from some one out side of Ñuu Saví (Mixtec) culture to learn how to do an ethnodrama? A healer and rain maker from Mixteca land is teaching me how to ask for rain and cure diseases. “Kutù’và yu Tu’ún Va’á”, is the name of my thesis and means “I am learning the wellness word”. This work is an “ethnodramatic initiation” to their sacred language. I don’t attempt to read Don Marcelino’s mind but to create a mental scenario that would help us to contemplate the internal spectacle he and his community watch during the ethnodrama of rain and healing. Finally I will represent my learning process during my initiation to body-mental technics. The subject of the thesis travels around several concepts interrelated: feast, ritual, celebration, healing, rain, knowledge, magical thinking, learning, performance… It’s related to an analogic language, oral culture, holistic perception and ethnodramaturgy. I will apply some of the concepts of Weisz’s ethnodramatic performance theory to a place located in Mexico, state of Oaxaca, Juxtlahuaca district, belonging to the municipality of Coicoyán de las Flores, El Jicaral. A wiseman from Nuun Tiaxin, Ñuu Saví, is teaching me how to speak with Rain and Sicknesses. Ethnodrama is a word used by Weisz to make the difference between theatre, and an ethnic paratheatrical performance. The ethnic drama is a mythological text, that it is seen inside the mind of the community members. Weisz conceives the concept as part of a greater project called, Anthropology of Knowledge, that studies the imaginary solutions to explain the formation of the world, the universe and the inscribed rituals in all great antique cultures Weisz [1994b:29]. Curanderismo, quackery, belongs to a illegitimate literature, it is something no serious. An art that goes beyond the canons of a written text and does not match with the categories of our cultures. It threatens the monolithic solidity of our academic reality and then it’s excluded. Weisz proposes to study shamanic text from a marginal position in front of a central culture that only recognizes as valid certain texts. The ethnotexto is uncomfortable, it intimidates the unity of the group of the dominant culture. Curanderismo places itself then in a position that questions a conceptual colonization, that “behavior and ideology that nourish themselves from a totalizing strategy”. A colonization that transcends Europe, related to power and to the dominant position. This is how Literature field is created Weisz [2005: 102-103]...

To shed light on the potential efficacy of cycling as a testing modality in the treatment of intermittent claudication (IC), this study compared physiological and symptomatic responses to graded walking and cycling tests in claudicants. Sixteen subjects with peripheral arterial disease (resting ankle: brachial index (ABI) < 0.9) and IC completed a maximal graded treadmill walking (T) and cycle (C) test after three familiarization tests on each mode. During each test, symptoms, oxygen uptake (VO2), minute ventilation (VE), respiratory exchange ratio (RER) and heart rate (HR) were measured, and for 10 min after each test the brachial and ankle systolic pressures were recorded. All but one subject experienced calf pain as the primary limiting symptom during T; whereas the symptoms were more varied during C and included thigh pain, calf pain and dyspnoea. Although maximal exercise time was significantly longer on C than T (690 +/- 67 vs. 495 +/- 57 s), peak VO2, peak VE and peak heart rate during C and T were not different; whereas peak RER was higher during C. These responses during C and T were also positively correlated (P < 0.05) with each other, with the exception of RER. The postexercise systolic pressures were also not different between C and T. However, the peak decline in ankle pressures from resting values after C and T were not correlated with each other. These data demonstrate that cycling and walking induce a similar level of metabolic and cardiovascular strain, but that the primary limiting symptoms and haemodynamic response in an individual's extremity, measured after exercise, can differ substantially between these two modes.

A planar polynomial differential system has a finite number of limit cycles. However, finding the upper bound of the number of limit cycles is an open problem for the general nonlinear dynamical systems. In this paper, we investigated a class of Liénard systems of the form x'=y, y'=f(x)+y g(x) with deg f=5 and deg g=4. We proved that the related elliptic integrals of the Liénard systems have at most three zeros including multiple zeros, which implies that the number of limit cycles bifurcated from the periodic orbits of the unperturbed system is less than or equal to 3.

An unstructured mesh �nite volume discretisation method for simulating di�usion in anisotropic media in two-dimensional space is discussed. This technique is considered as an extension of the fully implicit hybrid control-volume �nite-element method and it retains the local continuity of the ux at the control volume faces. A least squares function recon- struction technique together with a new ux decomposition strategy is used to obtain an accurate ux approximation at the control volume face, ensuring that the overall accuracy of the spatial discretisation maintains second order. This paper highlights that the new technique coincides with the traditional shape function technique when the correction term is neglected and that it signi�cantly increases the accuracy of the previous linear scheme on coarse meshes when applied to media that exhibit very strong to extreme anisotropy ratios. It is concluded that the method can be used on both regular and irregular meshes, and appears independent of the mesh quality.
