Descosiendo géneros : Canotaje, kayakismo, grupalidad y diversidad en el Centro de Educación Física Nº 67 de Berisso

Este escrito desea "navegar" en la construcción del canotaje y kayakismo en el CEF Nº 67 de Berisso, como una de las extensiones del mismo, pero que tiene la particularidad de ser junto a la gimnasia deportiva y la vida en la naturaleza, las extensiones fundadoras de nuestro CEF de Berisso, allá por el año 1998. Durante más de un cuarto de siglo, la sociedad y la ciudad de Berisso fue cambiandoy en particular la actividad de canotaje y Kayakismo en su organización dentro del CEF 67, la cual fue atravesada por la perspectiva de géneros. Reflexionemos desde esta mirada la enseñanza del kayakismo y el canotaje situándolo desde la diversidad y la apropiación de los cuerpos, que se conciben e inventan al elegir esta actividad recreativa o deporte en su origen, donde se recrean los sentidos y significados sobre la misma

Ki-67 Proliferation Index in Gastric Cancer - Biologic Significance

Objectives/Introdution: Ki-67 protein has been used as an indicator of proliferation activity in tumor cells. In gastric cancer the prognostic value has not been fully understood. This study was designed to assess the biologic significance of Ki-67 proliferation index (PI) in gastric cancer. Material/Methods: Seventy-two patients with gastric cancer were evaluated. These patients underwent gastric resection, and the tumor tissue was stained immunohistochemically. Ki-67 PI was defined as the percentage of tumor cells positive for Ki-67. Ki-67 PI was correlated with clinicopathological characteristics and patient survival. Results: A low Ki-67 PI (less than or equal to 50%) was associated with poorly differentiated histology - diffuse type (p=0.009) and signet ring cells (p=0.004) - and younger age (p=0.022). A worse prognosis in patients with low Ki-67 PI was also found (a mean survival of 41.8 vs 63 months for high Ki-67 PI group), but not statistically significant (p=0.623, log rank test). Discussion/Conclusion: We found an inversely correlation between Ki-67 PI and histological differentiation grade. Patients in group with low Ki-67 PI are younger, with poorly differentiated histology and have a lower mean survival. Like other studies already suggested, we may have two different tumors phenotypes - highly invasive with low proliferative capability, and less invasive potential with higher proliferative ability. However, in this sample, no significant prognostic value was achieved between both.

Symmetry reduction due to gallium substitution in the garnet Li6.43(2)Ga0.52(3)La2.67(4)Zr2O12

Single-crystal structure refinements on lithium lanthanum zirconate (LLZO; Li7La3Zr2O12) substituted with gallium were successfully carried out in the cubic symmetry space group I [Formula: see text]3d. Gallium was found on two lithium sites as well as on the lanthanum position. Due to the structural distortion of the resulting Li6.43(2)Ga0.52(3)La2.67(4)Zr2O12 (Ga-LLZO) single crystals, a reduction of the LLZO cubic garnet symmetry from Ia[Formula: see text] d to I [Formula: see text]3d was necessary, which could hardly be analysed from X-ray powder diffraction data.

Physiological and symptomatic responses to cycling and walking in intermittent claudication

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.

The effect of alternate supply of shielding gases in austenite stainless steel GTA welding

Welding system has now been concentrated on the development of new process to achieve cost savings, higher productivity and better quality in manufacturing industry. Discrete alternate supply of shielding gas is a new technology that alternately supplies the different kinds of shielding gases in weld zone. As the newdevelopedmethods compared to the previous generalwelding with a mixing supply of shielding gas, it cannot only increase thewelding quality, but also reduce the energy by 20% and the emission rate of fume. As a result, under thesamewelding conditions,comparedwith thewelding by supplying pure argon, argon + 67% helium mixture by conventional method and thewelding by supplying alternately pure argon and pure helium by alternate method showed the increased welding speed. Also, the alternate method showed the same welding speed with argon + 67% helium mixture without largely deteriorating of weld penetration. The alternate method with argon and helium compared with the conventional methods of pure argon and argon + 67% helium mixture produced the lowest degree of welding distortion.

Characteristics of alternate supply of shielding gases in aluminum GMA welding

Recently, unlike conventional method in supplying shielding gas, a newly method which alternately supplies different kinds of shielding gases in weld zone is developed and partly commercialized. However, literature related to the present status of the technology in the actual weld field is very scant. To give better understand on this technology, this study was performed. Compared with conventional gas supply method, the variations of weld porosity and weld shape in aluminum welding with alternate supply method of pure argon and pure helium were compared with conventional gas supply method with pure argon and argon + 67%helium mixture, respectively. As a result, compared with the welding by supplying pure argon and argon + 67%helium mixture by conventional method, the welding by supplying alternately pure argon and pure helium, produced lower degree of weld porosity and deeper and broader weld penetration profile.

Causes of injuries resulting in hospitalisation in Australia : assessing coder agreement on external causes

Objective: To assess extent of coder agreement for external causes of injury using ICD-10-AM for injury-related hospitalisations in Australian public hospitals. Methods: A random sample of 4850 discharges from 2002 to 2004 was obtained from a stratified random sample of 50 hospitals across four states in Australia. On-site medical record reviews were conducted and external cause codes were assigned blinded to the original coded data. Code agreement levels were grouped into the following agreement categories: block level, 3-character level, 4-character level, 5th-character level, and complete code level. Results: At a broad block level, code agreement was found in over 90% of cases for most mechanisms (eg, transport, fall). Percentage disagreement was 26.0% at the 3-character level; agreement for the complete external cause code was 67.6%. For activity codes, the percentage of disagreement at the 3-character level was 7.3% and agreement for the complete activity code was 68.0%. For place of occurrence codes, the percentage of disagreement at the 4-character level was 22.0%; agreement for the complete place code was 75.4%. Conclusions: With 68% agreement for complete codes and 74% agreement for 3-character codes, as well as variability in agreement levels across different code blocks, place and activity codes, researchers need to be aware of the reliability of their specific data of interest when they wish to undertake trend analyses or case selection for specific causes of interest.
