Roe, M and Malone, S. Yo-Yo intermittent recovery test performance in subelite Gaelic football players from under thirteen to senior age groups. J Strength Cond Res 30 (11): 3187-3193, 2016-Gaelic football is indigenous to Ireland and has similar locomotion profiles to soccer and Australian Football. Given the increasing attention on long-term player development, investigations on age-related variation in Yo-Yo intermittent recovery test level 1 (Yo-YoIR1) performance may provide useful information in talent identification, program design, and player monitoring. Therefore, the aim of this study was to evaluate Yo-YoIR1 performance across Gaelic football age groups. Male participants (n = 355) were recruited from division one, Gaelic football teams. Participants were allocated to one of the 7 groups according to respective age groups from under 13 (U13), under 14, under 15 (U15), under 16 (U16), minor, under 21 (U21), to senior age groups. Total Yo-YoIR1 distance (m) increased progressively from U13 (885 ± 347 m) to U16 (1,595 ± 380 m) equating to a rate of change of 180.2%. In comparison to U13, total distance at minor (1,206 ± 327 m) increased by 136.4%. Subsequent increases were observed in U21 (1,585 ± 445 m) and senior players (2,365 ± 489). Minimum (800-880 m) and maximum (2,240-2,280 m) total distances were comparable for U15, U16, and U21 players. Differences in total distance (m) for all age groups were statistically significant when compared to U13 players (p age groups for total distance was deemed to be large (effect size > 0.8). Similar trends were observed for maximum velocity and estimated V[Combining Dot Above]O2max. The evolution of Yo-YoIR1 performance in Gaelic football players from adolescents to adulthood highlights how maturation may influence sport-related running ability. Changes in Yo-YoIR1 performance should be closely monitored to optimize interventions for individuals transitioning across age groups.

Electro-Mechanical Modeling and Performance Analysis of Floating Wave Energy Converters Utilizing Yo-Yo Vibrating System

2015-01-01

This paper proposes a floating-type wave energy conversion system that consists of a mechanical part (yo-yo vibrating system, motion rectifying system, and power transmission system) and electrical part (power generation system). The yo-yo vibrating system, which converts translational input to rotational motion, is modeled as a single degree-of-freedom system. It can amplify the wave input via the resonance phenomenon and enhance the energy conversion efficiency. The electromechanical model is established from impedance matching of the mechanical part to the electrical system. The performance was analyzed at various wave frequencies and damping ratios for a wave input acceleration of 0.14 g. The maximum output occurred at the resonance frequency and optimal load resistance, where the power conversion efficiency and electrical output power reached 48% and 290 W, respectively. Utilizing the resonance phenomenon was found to greatly enhance the performance of the wave energy converter, and there exists a maximum power point at the optimum load resistance

The objectives of this study were to examine the effects of a moderate intensity strength training on changes in critical velocity (CV), anaerobic running distance (D'), sprint performance and Yo-Yo intermittent running test (Yo-Yo IR1) performances. two recreational soccer teams were divided in a soccer training only group (SO; n = 13) and a strength and soccer training group (ST; n = 13). Both groups were tested for values of CV, D', Yo-Yo IR1 distance and 30-m sprint time on two separate occasions (pre and post intervention). The ST group performed a concurrent 6-week upper and lower body strength and soccer training, whilst the SO group performed a soccer only training. after the re-test of all variables, the ST demonstrated significant improvements for both, YoYo IR1 distance (p = 0.002) and CV values (psoccer training significantly improves CV, Yo-Yo IR1 whilst moderately improving 30-m sprint performances in non-previously resistance trained male soccer players. Critical Velocity can be recommended to coaches as an additional valid testing tool in soccer.

Quantum local quench, AdS/BCFT and Yo-Yo string

International Nuclear Information System (INIS)

Astaneh, Amin Faraji; Mosaffa, Amir Esmaeil

2015-01-01

We propose a holographic model for local quench in 1+1 dimensional Conformal Field Theory (CFT). The local quench is produced by joining two identical CFT’s on semi-infinite lines. When these theories have a zero boundary entropy, we use the AdS/Boundary CFT proposal to describe this process in terms of bulk physics. Boundaries of the original CFT’s are extended in AdS as dynamical surfaces. In our holographic picture these surfaces detach from the boundary and form a closed folded string which can propagate in the bulk. The dynamics of this string is governed by the tensionless Yo-Yo string solution and its subsequent evolution determines the time dependence after quench. We use this model to calculate holographic Entanglement Entropy (EE) of an interval as a function of time. We propose how the falling string deforms Ryu-Takayanagi’s curves. Using the deformed curves we calculate EE and find complete agreement with field theory results.

Full Text Available Yoğurdun kurutulmasının temel amacı yoğurdu yüksek kalitede, soğutma gereksinimi olmadan, raf ömrünü arttırarak toz formunda saklamaktır. Türkiye’de bölgesel olarak yoğurdun raf ömrünü uzatmak amacıyla süzerek suyunu uzaklaştırma (süzme yoğurt, güneşte kurutma gibi çeşitli yöntemler kullanılmakla birlikte endüstriyel düzeyde yoğurt tozu üretimi yapılmamaktadır. Yoğurdu kurutmak için dondurarak kurutma, püskürtmeli kurutma, mikrodalga kurutma veya konvektif kurutma gibi kurutma yöntemleri uygulanmaktadır. Yoğurt tozu kalitesini canlı yoğurt starter bakteri sayısı önemli ölçüde etkilemektedir. Yoğurt tozu, canlı bakteri sayısı açısından değerlendirildiğinde en iyi kurutma yönteminin dondurarak kurutma olduğu belirtilmekle birlikte, çok pahalı bir yöntem oluşu önemli bir dezavantaj olarak görünmektedir. Diğer taraftan püskürtmeli kurutma yöntemi, yüksek su buharlaşma hızı, daha düşük maliyet ve kısa işlem süresi ile dondurarak kurutma yöntemine karşı avantajlar sağlamaktadır. Dondurarak kurutulmuş yoğurt, 4 ºC’da 1-2 yıl depolanabilmekte, püskürtmeli kurutucuda kurutulmuş yoğurt ise soğuk ve kuru koşullar altında saklandığında aktif kültürler 1 yıl canlılıklarını koruyabilmektedir. 1 yıllık depolama sonrasında, yoğurt tozunun en az 106kob/g düzeyinde toplam canlı yoğurt bakterisi içermesi gerekmektedir.

An InYO3 photocatalyst was prepared through a precipitation method and used for the degradation of molasses fermentation wastewater. The InYO3 photocatalyst characterized by X-ray diffraction (XRD), UV-Vis diffuse reflectance spectroscopy, surface area and porosimetry. Energy band structures and density of states were achieved using the Cambridge Serial Total Energy package (CASTEP). The results indicated that the photodegradation of molasses fermentation wastewater was significantly enhanced in the presence of InYO3 when compared with PbWO4. The calcination temperature was found to have a significant effect on the photocatalytic activity of InYO3. Specifically, InYO3 calcined at 700 degrees C had a considerably larger surface area and lower reflectance intensity and showed higher photocatalytic activity. The mathematical simulation results indicated that InYO3 is a direct band gap semiconductor, and its conduction band is composed of In 5p and Y 4d orbitals, whereas its valence band is composed of O 2p and In 5s orbitals.

Players were divided into three age groups (U15, U17 and U19 and completed three YYIR1 in three consecutive weeks. Pairwise comparisons were used to investigate test reliability (for distances and heart rate responses using technical error (TE, coefficient of variation (CV, intra-class correlation (ICC and limits of agreement (LOA with Bland-Altman plots. The mean YYIR1 distances for the U15, U17 and U19 groups were 2024 ± 470 m, 2404 ± 347 m and 2547 ± 337 m, respectively. The results revealed that the TEs varied between 74 and 172 m, CVs between 3.0 and 7.5%, and ICCs between 0.87 and 0.95 across all age groups for the YYIR1 distance. For heart rate responses, the TEs varied between 1 and 6 bpm, CVs between 0.7 and 4.8%, and ICCs between 0.73 and 0.97. The small ratio LOA revealed that any two YYIR1 performances in one week will not differ by more than 9 to 28% due to measurement error. In summary, the YYIR1 performance and the physiological responses have proven to be highly reliable in a sample of Belgian high-level youth soccer players, aged between 13 and 18 years. The demonstrated high level of intermittent endurance capacity in all age groups may be used for comparison of other prospective young soccer players.

The aim of this study was to investigate the effect of time-of-day on oxidative stress, cardiovascular parameters, muscle damage parameters, and hormonal responses following the level-1 Yo-Yo intermittent recovery test (YYIRT). A total of 11 healthy subjects performed an intermittent test (YYIRT) at two times-of-day (i.e., 07:00 h and 17:00 h), with a recovery period of ≥36 h in-between, in a randomized order. Blood samples were taken at the rest (baseline) and immediately (post-YYIRT) after the YYIRT for measuring oxidative stress, biochemical markers, and hormonal response. Data were statistically analyzed using one-way and two-way repeated measures ANOVA and Bonferroni test at p creatine kinase (p  0.05) were similar for the morning and evening test. In conclusion, our findings suggest that aerobic performance presents diurnal variation with great result observed in the evening accompanied by an improvement of hormonal, metabolic, and oxidative responses. These data may help to guide athletes and coaches and contribute to public health recommendations on exercise and muscle damage particularly in the competitive periods.

Full Text Available Bu çalışmada, hidrofobik ve iyonik interaksiyonların koyulaştırılmış yoğurt jellerinin fiziksel özellikleri üzerindeki rolü araştırılmıştır. Konsantre yoğurt üretiminde, ultrafiltrasyon (UF, reverse osmosis (RO ve direk rekonstitüsyon (DR teknikleri kullanılmıştır. Yoğurtların fiziksel özellikleri bir dinamik reometre aracılığı ile ölçülmüştür. Reometrenin çalışma parametreleri 1.5x10-2-1.5x10-1 mNm ve frekansı 0.25 Hz olarak kalibre edilmiştir. Farklı kurumadde artırım tekniklerinin süt proteinlerinde yarattığı değişimler ise doğal-poliakrilamid jel elektroforez ile incelenmiştir. Sonuçlara göre, hidrofobik interaksiyonların en az kovalent bağlar kadar yoğurt jelinin oluşumunda etkin rol oynadığı saptanmıştır. 2 oC’de glucono-delta-lactone ile asitlendirilen yoğurtlarda pıhtının son derece zayıf olduğu ve proteinler arası interaksiyonların tamamlanmadığı gözlenmiştir. Buna karşın, CaCl2 katımı UF-yoğurt dışında tüm örneklerde herhangi bir fiziksel değişime neden olmamıştır. Ancak, UF-yoğurtta CaCl2 konsantrasyonuna bağlı olarak dereceli bir düşüş saptanmıştır.

The aim of the study was to investigate the effect of a flavonoid-rich fresh fruit juice on cardiovascular, oxidative stress, and biochemical parameters during the yo-yo intermittent recovery test (YYIRT). Twenty-two healthy males subjects participated in this study divided into two groups: An experimental group (EG: n  = 11) who consumed the antioxidant supplement and a control group (CG: n  = 11). All participants performed two test sessions at 07:00 hr before and after 2 weeks of supplementation with Opuntia ficus-indica juice. Blood samples were taken before (P1) and immediately (P2) after the YYIRT. Our results showed that following the 2,2-diphenyl-1- picrylhydrazyl (DPPH ● ) test, the Opuntia ficus-indica juice has an antioxidant capacity for capturing free radicals ( p  Opuntia ficus-indica juice before and immediately after YYIRT. However, no significant effect on HDL ( p  > .05), GLC ( p  > .05) levels nor the SBP and DBP ( p  > .05) was observed after supplementation with Opuntia ficus-indica juice. The supplementation leads to an improvement on YYIRT performance (The total distance covered during the YYIRT, V O 2max , VMA) and the rating of perceived exertion (RPE). Opuntia ficus-indica juice has a potent antioxidant activity that reduces total and LDL-cholesterol with only a moderate lowering of HDL-cholesterol and oxidative stress. Moreover, supplementation decreases muscle damage caused by the endurance exercise.

Elastic neutron diffuse scattering has been measured in cubic Zr(Ca, Y)O 2-x at room temperature. The very high diffuse scattering (up to 70 Laue) is explained mostly by the oxygen displacements along directions, and by Ca displacements along . The weak short-range order contribution strongly suggests that oxygen vacancies tend to place as second rather than at first neighbours of a Ca stabilizing ion

The ability to complete high-intensity running is essential for soccer. The Yo-Yo Intermittent Recovery Test Level 2 (YYIRT2) can measure this capacity, but there is limited information regarding this assessment in collegiate female soccer players. This study investigated the YYIRT2 as a measure of high-intensity running in this population, and its relationship to other soccer field tests. Twenty-one players from a Division I team were recruited. In addition to the YYIRT2, subjects completed linear (0-5, 0-10, and 0-30 m sprint intervals) and change-of-direction (pro-agility and 60-yard shuttle) speed tests, as well as the YYIRT Level 1 (YYIRT1), to assess relationships with YYIRT2 by correlations (p ≤ 0.05). The correlation of YYIRT1 with the speed tests was also assessed. The YYIRT1 and YYIRT2 were standardized using z-scores for comparison with elite benchmarks to investigate relative performance on each test. The YYIRT2 and YYIRT1 distances did not significantly correlate with those of the speed tests (r = -0.251 to 0.274). There was a large relationship between YYIRT2 and YYIRT1 distances (r = 0.582), although the explained variance was low (33.87%). Mean YYIRT2 z-scores (-4.29 ± 1.66) indicated a performance further from elite benchmarks than those of the YYIRT1 (-1.92 ± 1.61), and 90.5% (19 of 21) subjects performed relatively better in the YYIRT1 than YYIRT2. The YYIRT2 provided a more specific measure of high-intensity running to that of the YYIRT1 in collegiate female soccer players. Coaches may consider using the YYIRT2 to gauge and track progress of high-intensity running capabilities and create training programs to improve this ability in female players.

Bi{sub 2}YO{sub 4}Cu{sub 2}Se{sub 2} possesses a low thermal conductivity and high electrical conductivity at room temperature, which was considered as a potential thermoelectric material. In this work, we have investigated the electrical and thermal transport properties of Bi{sub 2}YO{sub 4}Cu{sub 2}Se{sub 2} system in the temperature range from 300 K to 873 K. We found that the total thermal conductivity decreases from ~1.8 W m{sup −1} K{sup −1} to ~0.9 W m{sup −1} K{sup −1}, and the electrical conductivity decreases from ~850 S/cm to ~163 S/cm in the measured temperature range. To investigate how potential of Bi{sub 2}YO{sub 4}Cu{sub 2}Se{sub 2} system, we prepared the heavily Iodine doped samples to counter-dope intrinsically high carrier concentration and improve the electrical transport properties. Interestingly, the Seebeck coefficient could be enhanced to ~+80 μV/K at 873 K, meanwhile, we found that a low thermal conductivity of ~0.7 W m{sup −1} K{sup −1} could be achieved. The intrinsically low thermal conductivity in this system is related to the low elastic properties, such as Young's modulus of 70–72 GPa, and Grüneisen parameters of 1.55–1.71. The low thermal conductivity makes Bi{sub 2}YO{sub 4}Cu{sub 2}Se{sub 2} system to be a potential thermoelectric material, the ZT value ~0.06 at 873 K was obtained, a higher performance is expected by optimizing electrical transport properties through selecting suitable dopants, modifying band structures or by further reducing thermal conductivity through nanostructuring etc. - Highlights: • The total thermal conductivity decreases from 1.8 to 0.9 Wm{sup –1}K{sup –1} at 300–873K. • The electrical conductivity decreased from 850 to 163 S/cm at 300–873K. • The Seebeck coefficients were enhanced through heavily Iodine doping. • The ZT ~0.06 at 873K suggests that Bi{sub 2}YO{sub 4}Cu{sub 2}Se{sub 2} systems are potential thermoelectrical materials.

‘Optimism against all odds’: Polish National Identity in War Films of Jerzy Passendorfer

Full Text Available ‘Optimism against all odds’: Polish National Identity in War Films of Jerzy Passendorfer Using archival sources, movie reviews, secondary sources and films, this article examines the cinema of Jerzy Passendorfer, the founding father of action movies genre in People’s Poland, but also the staunch supporter of Władysław Gomułka’s ‘Polish road to Socialism’ and General Mieczysław Moczar’s ultranationalist faction of the Partisans in the Polish United Workers’ Party. It demonstrates how Passendorfer’s blend of mainstream cinema and propaganda legitimized the party state and contributed to the construction of a new ethos, identity, and politics of history that enforced historical amnesia and syncretized past and present. It also argues that Passendorfer’s promotion of nationalist and authoritarian state ideology, militaristic patriotism and Polish-Soviet alliance, commissioned by the regime, sat well with mass audiences, precisely because of the use of popular genres adopted from the West and the quench for optimistic visions of nationhood. Although Passendorfer’s patriotic actions flicks faded away with the fall of Gomułka’s regime, they constitute a model, which can be still emulated.   “Trudny optymizm”: polska tożsamość narodowa w filmach wojennych Jerzego Passendorfera Opierając się na źródłach archiwalnych, publikacjach naukowych i analizie filmów, niniejszy artykuł bada twórczość filmową Jerzego Passendorfera, ojca chrzestnego filmu akcji w PRL, zwolennika ‘polskiej drogi do socjalizmu’ Władysława Gomułki oraz sympatyka nacjonalistycznej frakcji generała Mieczysława Moczara w Polskiej Zjednoczonej Partii Robotniczej.

For many scientific questions gaining three-dimensional insight into a specimen can provide valuable information. We here present an instrument called "tOMography Nano crYo (OMNY)," dedicated to high resolution 3D scanning x-ray microscopy at cryogenic conditions via hard X-ray ptychography. Ptychography is a lens-less imaging method requiring accurate sample positioning. In OMNY, this in achieved via dedicated laser interferometry and closed-loop position control reaching sub-10 nm positioning accuracy. Cryogenic sample conditions are maintained via conductive cooling. 90 K can be reached when using liquid nitrogen as coolant, and 10 K is possible with liquid helium. A cryogenic sample-change mechanism permits measurements of cryogenically fixed specimens. We compare images obtained with OMNY with older measurements performed using a nitrogen gas cryo-jet of stained, epoxy-embedded retina tissue and of frozen-hydrated Chlamydomonas cells.

Full Text Available Recientes estudios están empezando a abrir la obra de Ralph Waldo Emerson, a quien John Dewey una vez se refirió como «el Filósofo de la Democracia», hacia lecturas de tipo social y político. Este artículo, busca promover la fuerza y el potencial de este nuevo emersonianismo para la filosofía de la educación mostrando cómo las nociones de autosuficiencia y de aversión a la conformidad definidas por Emerson, no son inherentemente antisociales, amorales, o apolíticas. El artículo defiende, en primer lugar, que lo que Emerson propone es una comprensión del yo y de la sociedad que impide cualquier tipo de contraposición entre los dos conceptos de «auto-suficiencia». En segundo lugar, se realiza una lectura detenida de su ensayo tardío «Experiencia» donde presenta su crítica sobre la particular concepción occidental del pensamiento que tiende considerar a este con arreglo a sus consecuencias políticas. Si existe alguna esperanza para el yo individual, entonces, para Emerson, debe existir siempre la esperanza también de una sociedad democrática. Con ello, intenta recordarnos que el requisito para una sociedad democrática consiste en tomarse en serio la subjetividad de la mirada de cada uno de sus miembros. Recibido: 18/01/2013 / Aceptado: 26/03/2013Cómo referenciar este artículoSchumann, C.

Full Text Available Esta reflexión se refiere a la figura del autor una vez que esta figura se traslada al medio digital, esto es, a un espacio donde se puede mirárselo de forma permanente. Ese traslado impone algunos cambios en la elaboración de una entidad autorial por parte del escritor, o sea, la persona física, el individuo que escribe, “l’écrivant”, según Roland Barthes. Este paso al medio digital está deslegitimando la figura del autor de nuestros días y, por ende, cambiando el role del escritor contemporáneo. Así, la reacción por parte del escritor está siendo su espectacularización. Discuto este tema desde el concepto de ego-historias, experiencias personales en el texto en primera persona, por medio de algunas características presentes en dos narrativas: O espírito da prosa (2012, de Cristovão Tezza, y La parte inventada (2014, de Rodrigo Frésan. Busco evidenciar cómo los medios digitales, la cultura digital y mediática en general favorecen una reflexión metaliteraria sobre la invención de un “yo-autor-escritor” que satisface la necesidad del exhibicionismo que los medios digitales proporcionan en la construcción de su imagen.

Full Text Available El presente artículo tiene como propósito caracterizar las relaciones existentes entre la discrepancia del Yo, las actitudes hacia la compra y valores materialistas en estudiantes de Pedagogía considerando diferencias de género. Se aplicaron las escalas de Discrepancia del Yo, Actitudes hacia la Compra y Valores Materiales, en una muestra de 167 estudiantes chilenos de las carreras de Pedagogía en Historia de dos universidades del Sur de Chile. Los resultados obtenidos, evidencian correlaciones significativas entre las dimensiones de discrepancia del Yo físico, intelectual y económico, y las actitudes impulsivas y compulsivas hacia la compra; así como en las dimensiones de valores materiales vinculadas al éxito social y felicidad personal. En cuanto al género, se observa en las mujeres un perfil de ambivalencia actitudinal, donde coexiste la racionalidad con la compulsividad. A partir de la relevancia social del futuro ejercicio profesional de los estudiantes de pedagogía, los resultados se discuten considerando la importancia de la inclusión de la educación económica y financiera en la formación inicial de profesores, con un fuerte énfasis en la toma de conciencia acerca de sus actitudes y valores hacia el consumo.

2014-06-01

Full Text Available El presente trabajo se propone analizar la posición de Daniel Dennett con respecto a la realidad y naturaleza del yo. El autor considera que la concepción del yo humano propia del sentido común, en tanto que un elemento único, simple, idéntico y continuo, es fundamentalmente una ficción. A partir de este diagnóstico, Dennett se propone ofrecer una explicación de este fenómeno ilusorio desde una doble perspectiva: la heterofenomenología y la memética. La primera y segunda parte de este trabajo estarán destinadas a desarrollar respectivamente estos dos enfoques. En la tercera parte serán analizadas las afirmaciones hechas por el autor dentro de los mencionados marcos teóricos, con el objetivo de mostrar que ambos desarrollos no se complementan entre sí, sino que, por el contrario, presentan ciertas contradicciones a la hora de reconstruir la postura dennettiana global con respecto al yo humano.

The present investigation aims to demonstrate the potentiality of Eu{sup 3+}/Sm{sup 3+} single-doped and co-doped Ca{sub 4}YO(BO{sub 3}){sub 3} phosphors, which were prepared by a sol–gel method. The X-ray diffraction (XRD) profiles showed that all the observed peaks could be attributed to the monoclinic phase of Ca{sub 4}YO(BO{sub 3}){sub 3}. From the measured emission profiles, we have noticed that both the single-doped Eu{sup 3+}/Sm{sup 3+} phosphors shows four emission transitions of {sup 5}D{sub 0} → {sup 7}F{sub 0,1,2,3} and {sup 4}G{sub 5/2} → {sup 6}H{sub 5/2,7/2,9/2,11/2} respectively. Among them, the {sup 5}D{sub 0} → {sup 7}F{sub 2} of Eu{sup 3+} and {sup 4}G{sub 5/2} → {sup 6}H{sub 7/2} of Sm{sup 3+} are intense emission transitions, leading to an intense red color emission from the prepared phosphors. The excitation spectra showed that Eu{sup 3+}/Sm{sup 3+} doped samples can be excited efficiently by 394 nm and 402 nm respectively, incidentally which matches well with the characteristic emission from UVLED. The co-doping of Sm{sup 3+} ions can broaden and strengthen the absorption of near UV region and to be efficient to sensitize the emission of the Ca{sub 4}YO(BO{sub 3}){sub 3}:Eu{sup 3+} phosphor. The mechanism involved in the energy transfer between Eu{sup 3+} and Sm{sup 3+} has been explained and elucidated by an energy level diagram. - Highlights: • Eu{sup 3+} or/and Sm{sup 3+}:Ca{sub 4}YO(BO{sub 3}){sub 3} phosphors were prepared by sol–gel method. • The co-doping of Sm{sup 3+} to Ca{sub 4}YO(BO{sub 3}){sub 3}:Eu{sup 3+} extends its absorption of NUV region. • It has intense absorption in NUV region, which is suitable for NUV LED. • The energy transfer process between Eu{sup 3+} and Sm{sup 3+} ions were discussed.

From Little Words, Big Words Grow: Annotations on the Yo, Sí Puedo Experience in Brewarrina, Australia

Liliana E. Correa

2017-10-01

Full Text Available This article is a reflection on the application of the Cuban literacy methodology Yo, Sí Puedo to the Australian setting. The Yo, Sí Puedo / Yes, I Can! model developed in Cuba by the Instituto Pedagógico Latinoamericano y Caribeño, IPLAC (Institute of Pedagogy for Latin America and the Caribbean has been successfully implemented across the Global South as a strategy of adult literacy. It is a legacy of our Latin American revolutionary roots, with its origin in the Freirean pedagogy of the oppressed. Expanding across continents this model continues to teach reading and writing to disenfranchised adults in marginal and Indigenous communities, from the Argentinean Chaco to Brewarrina in northern NSW, Australia. Its aim is to contribute to the hope of improving the health and educational outcomes of the country’s First Peoples. This article is indebted to conversations with the Cuban advisor of Yes, I Can!, José Manuel Chala Leblanch. Observing him working in the classroom setting of Brewarrina touched me at different levels: personally because it reminded me of my own family experiences with the education system in my country, Argentina; and professionally as an educator negotiating different languages and cultures. It also reinforced my belief in the importance of incorporating Indigenous ways of learning and teaching to Western styles of teaching and learning. I built this reflection moving from personal and poetic—visual and textual—narratives and observations to academic interventions informed by researched literature on adult and Indigenous education.

We designed and evaluated for feasibility an intervention-Yo Puedo-that addresses social network influences and socioeconomic opportunities in a neighborhood with substantial gang exposure and early childbearing. Yo Puedo combined conditional cash transfers for completion of educational and reproductive health wellness goals with life skills sessions, and targeted youth 16-21 years of age and same-aged members of their social network. We conducted a two-arm study with social networks randomized to the intervention or a standard services control arm. We evaluated intervention uptake, adherence, and safety; and assessed evidence of effects on behavioral outcomes associated with unintended pregnancy and sexually transmitted infection risk. A total of 72 social networks composed of 162 youth enrolled, with 92% retention over 6 months. Seventy-two percent of youth randomized to the intervention participated in intervention activities: 53% received at least one conditional cash transfer payment and 66% came to at least one life skills session. We found no evidence that cash payments financed illicit or high-risk behavior. At 6 months, compared with controls, intervention participants had a lower odds of hanging out on the street frequently (odds ratio [OR], .54; p = .10) and a lower odds of reporting that their close friends had been incarcerated (OR, .6; p = .12). They reported less regular alcohol use (OR, .54; p = .04) and a lower odds of having sex (OR, .50; p = .04). The feasibility evaluation of Yo Puedo demonstrated its promise; a larger evaluation of effects on pregnancy and sustained behavioral changes is warranted.

1997-04-01

The determination of yttrium (Y) in water in the concentration range of 2 μg/ml to 200 μg/ml by laser enhanced ionisation (LEI) technique is reported. The YO band head at 584.27 nm belonging to A 2 Π - X 2 Σ + system is used for LEI signal detection. It is also shown that the LEI signal is enhanced when the mixture of air - acetylene - argon (AAA) is used instead of commonly used air-acetylene (AA) mixture. In the present work an XeCl laser (308 nm) pumped rhodamine 6G dye laser, covering a range of 570-610 nm is used. The sample/standard in solution form is aspirated into the flame with pneumatic nebulizer. The working curve is a straight line showing linear dependence of LEI signal with yttrium concentration. The relative standard deviation calculated at 100 μg/ml is found to be 2.4 %. (author)

Full Text Available Emotions belong human nature, they must not be disaggregated, however, they have been rejected by many disciplinary perspectives that overlap rational action to emotional in the analysis of collective action. Although recently the interest arises to analyze how emotions boost social mobilizations. The objective of this work is analyze the emotions arising in the context of the collective action which was taken by young Mexicans in the movement #Yo Soy 132 through social constructionism of emotions as the theoretical perspective and using as method the discourse analysis. This paper is presented in five parts: in the first the emotions in the collective action are discussed, subsequently the studied phenomenon is contextualized, in the third the analysis method is detailed, in the fourth, results are presented, and in the last section, the findings are confronted on the basis of theoretical approaches recovered. It is concluded that regardless of the context, emotions keep on a similar path in collective action, and the emerged emotions are not positive or negative, instead they are impulsor and detractor of such action.

Presenta un interrogante por el lugar de la subjetividad en el fundamento disciplinar de la psicología, tal como se la concibe contemporáneamente. Dentro de sus conclusiones se propone que esta disciplina puede pensarse alternativamente a su usual denominación de ciencia y cuestionarse en tanto Tecnología del yo, así como en la necesidad de interrogar por la noción de sujeto que está en la base de su concepto de enfermedad mental. Finalmente, se propone la pertinencia de la exploración de la obra de Michel Foucault para abordar este interrogante.

2014-01-01

Introducción: Las malformaciones del tubo neural (MTN) representan la segunda causa más frecuente de anomalías congénitas, luego de las cardiopatías. En este grupo se destaca el mielomeningocele (MMC) por su mayor incidencia, y por ser la más incapacitante y la más compleja entre todas las demás malformaciones del sistema nervioso c`entral (SNC). En Bolivia, como en muchos países de Sudamérica, los bajos niveles socio-culturales y la debilidad en el sistema sanitario, hacen que su incidencia y su morbilidad, sean mayores que en las naciones más desarrolladas. Material y Métodos: Se realizó un estudio retrospectivo y descriptivo de 70 casos de MMC, atendidos por un equipo multidisciplinario en el Hospital Universitario Japonés (HUJ) de Santa Cruz de la Sierra, entre 2008-2011. De ellos, 60 fueron intervenidos quirúrgicamente. Resultados: Se realizaron controles prenatales sólo en 27 mujeres (38.6%), diagnosticándose una disrafia espinal en apenas dos casos (7.4%). La edad de ingreso del MMC en su mayoría fue después de las 24 horas (65.6%), predominando su localización en la región lumbosacra (64.3%). De ellos, 67.2% eran abiertos, presentando un 32.9% un daño neurológico motor parcial mientras que 47.1% tenían paraplejia por debajo de la lesión. De los 70 casos, tres (4.3%) no fueron intervenidos, por presentar defectos congénitos severos o estado general grave. Las principales complicaciones posoperatorias inmediatas fueron: dehiscencia de sutura y/o infección de la herida (16.6%), fístula de líquido cefalorraquídeo (LCR) (10%) e infección del SNC (11.7%). La mortalidad general y postoperatoria fue de 7.1% y 3.3%, respectivamente. Al mes de vida presentaban hidrocefalia un 80% de los pacientes operados, colocándose una derivación ventriculoperitoneal (DVP) de presión media. De 9 pacientes que tuvieron un acompanamiento de dos o más años, seis presentaron una médula anclada, que fueron intervenidas quirúrgicamente. Conclusi

Hegemons and their law in the time of the Polish communism. An attempt at a constitutional, legal and philosophical analysis

Directory of Open Access Journals (Sweden)

Dawid Bunikowski

2010-12-01

Full Text Available The author, developing his theory of hegemony, interprets legal and real actions taken by the Secretaries of the Polish United Workers’ Party: Bierut, Gomułka, Gierek, General Jaruzelski, and by the Party itself. According to the constitutional and legal analysis, the Polish communist Secretaries did not often obey the law which was valid at the time. There are many examples of such actions: from illegal judicial processes „on demand of the authority”, through criminal sanctions as well as civic and real restrictions for members of the political opposition, to unofficial officials’ appointments or political directives/unofficial law of the Party, and marginalization of the due constitutional powers. The most controversial case of the realization of the hegemony law by the Party seems to be the enforcement of the martial law by General Jaruzelski in December 1981.

Trascendiendo al yo ensimismado. La ética de la atención de Iris Murdoch

Directory of Open Access Journals (Sweden)

Cuartango, Román

2006-12-01

Full Text Available Many of moral dilemmas would lose its intensity, thinks Iris Murdoch, if we left the confused idea of a sovereign will that chooses independently its courses of action. Paying attention to what constitutes the reality enables a sort of asceticism of the experience, that leads beyond the deliriums of an I absorbed. The exercise of estimating the details, the connections, the complexity, modifies the decision itself: it does not be a matter of electing, but of “seeing” the moral thing -the demand of the thing-, the same as an exact artist does not paint what “he likes” but “what it is there”.

Muchos de los dilemas morales perderían su intensidad, piensa Iris Murdoch, si abandonáramos la idea de una voluntad soberana que elige autónomamente sus cursos de acción. Prestar atención a la constitución de la realidad posibilita una suerte de ascesis experiencial que conduce más allá del los devaneos de un yo ensimismado. El ejercicio de apreciación de los detalles, de las conexiones, de la complejidad, modifica la decisión misma: no se trata de elegir, sino de “ver” lo moral –la exigencia de la cosa–, igual que un artista cabal no pinta lo que “le gusta” sino “lo que está ahí”.

Thermal conductivity of Na3(U/sub 1-y/Pu/sub y/)O4: A preliminary in-pile determination

International Nuclear Information System (INIS)

Lee, M.J.; Lambert, J.D.B.; Ukai, S.; Odo, T.

1987-01-01

During Run-Beyond-Cladding-Breach (RBCB) operation in an oxide LMR, the performance of a breached fuel element is intimately associated with the formation of fuel-sodium reaction product (FSRP), Na 3 (U/sub 1-y/Pu/sub y/)O 4 . In-pile experiments coupled with destructive examinations of breached fuel have consistently revealed noticeable changes in fuel structure accompanying FSRP formation at the fuel surface. Previous analyses have also indicated a significant impact of FSRP on fuel centerline temperature. Successful modeling of breached fuel thermal behavior therefore requires a reasonably accurate knowledge of the thermal properties of the FSRP, especially its thermal conductivity. But laboratory investigations have been scarce and limited to the Na/UO 2 system because of the toxicity of plutonium and hygroscopicity of the FSRP. Hence, post-irradiation observations of fuel samples remain the most amenable way of deriving the thermal conductivity of the FSRP. Such work is a spin-off of the RBCB program in the Experimental Breeder Reactor-II (EBR-II), a program jointly sponsored by the US Department of Energy and the Power Reactor and Nuclear Fuel Development Corporation of Japan

Breast cancer is less likely to be diagnosed at the earliest stage in Hispanic/Latino (Hispanic) women compared to non-Hispanic White women, even after accounting for differences in age, socioeconomic status, and method of detection. Moffitt Cancer Center created a comprehensive health education program called Yo me cuido (®) (YMC) to address and reduce breast cancer disparities among Spanish- and English-speaking Hispanic women by providing breast cancer and healthy lifestyles awareness and education, and promoting breast cancer screenings, reminders, and referrals for women 40 years and older. The purpose of this paper is to showcase the innovative approaches and methods to cancer prevention and early detection of the YMC program, and to promote it as an effective tool for improving outcomes in community health education, outreach, and engagement activities with Hispanic populations. Key components of the program include educational workshops, mammogram referrals, and a multimedia campaign. The YMC program is unique because of its approaches in reaching the Hispanic population, such as delivering the program with compassionate services to empower participants to live a healthier lifestyle. Additionally, direct follow-up for mammography screenings is provided by program staff. From 2011 to 2013, YMC has educated 2,226 women and 165 men through 93 workshops. About 684 (52 %) women ages 40 and older have had a screening mammogram within their first year of participating in the program. The YMC program is an innovative cancer education and outreach program that has demonstrated a positive impact on the lives of the Hispanic community in the Tampa Bay region.

In this study, nanocrystalline BaCryFe12-yO19 (0.0 ≤ y ≤ 1.0) hexaferrite powders were prepared by sol-gel auto combustion method and the effect of Cr3+ ion substitution on morphology, structure, optic and magnetic properties of Barium hexaferrite were investigated. X-ray powder diffraction (XRD) analyses confirmed the purity of all samples. The XRD data shows that the average crystallite size lies between 60.95 nm and 50.10 nm and same was confirmed by Transmission electron microscopy. Transmission electron and scanning electron microscopy analyses presented the hexagonal morphology of all products. The characteristic hysteresis (σ-H) curves proved the ferromagnetic feature of as grown nanoparticle samples. Specific saturation magnetization (σs) drops from 46.59 to 34.89 emu/g with increasing Cr content while the coercive field values lie between 770 and 1652 Oe. The large magnitude of the magnetocrystalline (intrinsic) anisotropy field, (Ha) between 11.0 and 12.6 kOe proves that all products are magnetically hard. The energy band gap values decrease from 2.0 eV to 1.84 eV with increasing Cr content. From 57Fe Mössbauer spectroscopy, the variation in line width, isomer shift, quadrupole splitting and hyperfine magnetic field values were determined and discussed.

Full Text Available Este trabajo tiene por objetivo analizar el poemario La Hybris (2007 de la escritora argentina Alicia Genovese, considerando la configuración del yo lírico y, asimismo, el tipo de política genérico-sexual que éste despliega. En este marco, es relevante revisar los sentidos que asume el juego de intertextualidad con la tragedia griega que propone el discurso del poemario. Ello se relaciona, por una parte, con la necesidad de confrontar un presente que se avizora complejo y confuso desde una tradición cultural que aporta construcciones ideológicas y sensibilidades comunitarias que pueden confrontarse con el propio contexto. Por otro lado, el juego intertextual posibilita dar sustento y legitimidad a una voz lírica que no solo expone la furia de ciertos padecimientos, sino que procura, dificultosamente, encontrar modos para que ese malestar se canalice de modo productivo.This article aims to analyze La Hybris (2009, a poetry book by the Argentine writer Alicia Genovese, considering the configuration of the lyric subject as well as the gender politics developed in the text. In this frame, it is relevant to observe the role of intertextuality, in particular, the dialogue established between the tradition of classic tragedles and the poems' discourses. The hypotesis ofthis work mantains that, referring to Greek tragedy, the poems may confront a present that is perceived both complex and confused. On the other hand, intertextuality functions as a way to give support and legitimacy to a lyric voice that not only aims to expose the fury caused by pain but also aspires to canalize her feelings productively.

Concerning the rapid prototyping (RP) system use new RP format and the related software, the paper promoted the international standardization in consideration of relationships with an international standard, STEP. RP, which is a technology to rapidly prototype a solid body based on the three-dimensional CAD data, is used in various fields of product manufacture, medical field, etc., and is expected to further expand its field of application. In this R and D, an international version of the RP software system developed for domestic use was developed, and at the same time a software was trially manufactured so that the data on STEP/AP203/CC5 and CC6 can be delivered to the system. Moreover, a plan on new AIC51X as the STEP/AIC suitable for PR was studied. Relating to these results, the paper conducted the publicity work to the persons concerned in RP in the U.S. and Europe, and also explained those at ISO/TC184/SC4 (STEP Conference). The PR use interface enabling highly rapid and accurate data processing reached to a stage of the international commercialization, and at the same time the study items were materialized for proposal of the new STEP standards suitable for RP. 18 refs., 80 figs., 12 tabs.

2014-09-01

Nanocrystalline La1-xSrxCo1-yFe yO3 (x=0.00-0.60) perovskites were fabricated by a cheap economic route (i.e. micro-emulsion method) and characterized by thermogravimetric analysis (TGA), X-ray diffraction (XRD), fourier transform infrared (FTIR) spectroscopy, and scanning electron microscopy (SEM). TGA analysis showed ~35% weight loss. The crystallite size determined by XRD and SEM ranged from 30 to 80 nm and ~30 to 50 nm, respectively. The dielectric behavior was evaluated in the range of 1.0×106 Hz to 3.0×10 9 Hz at 298 K, the dielectric parameters resulting appreciably enhanced by co-doping with Sr and Fe. The maximum dielectric parameters (ε′=103.35, ε″=58.92 and tan δ=0.57) were observed for La0.4Sr0.6Co0.4Fe0.6O 3 at 15×106 Hz. Results suggest the potential use of these nanocrystalline perovskites in GHz-operated microwave devices. © 2014 Elsevier Ltd and Techna Group S.r.l.

Precise control of composition and microstructure is critical for the production of (BaxSr1-x)Ti1+yO3+z (BST) dielectric thin films with the large dependence of permittivity on electric field, low losses, and high electrical breakdown fields that are required for successful integration of BST into tunable high-frequency devices. Here, we present results on composition-microstructure-electrical property relationships for polycrystalline BST films produced by magnetron-sputter deposition, that are appropriate for microwave and millimeter-wave applications such as varactors and frequency triplers. Films with controlled compositions were grown from a stoichiometric Ba0.5Sr0.5TiO3 target by control of the background processing gas pressure. It was determined that the (Ba+Sr)/Ti ratios of these BST films could be adjusted from 0.73 to 0.98 by changing the total (Ar+O2) process pressure, while the O2/Ar ratio did not strongly affect the metal ion composition. Film crystalline structure and dielectric properties as a function of the (Ba+Sr)/Ti ratio are discussed. Optimized BST films yielded capacitors with low dielectric losses (0.0047), among the best reported for sputtered BST, while still maintaining tunabilities suitable for device applications.

To compare relative match intensities of sea-level versus high-altitude native soccer players during a 2-week camp at 3600 m, data from 7 sea-level (Australian U17 National team, AUS) and 6 high-altitude (a Bolivian U18 team, BOL) native soccer players were analysed. Two matches were played at sea-level and three at 3600 m on Days 1, 6 and 13. The Yo-Yo Intermittent recovery test (vYo-YoIR1) was performed at sea-level, and on Days 3 and 10. Match activity profiles were measured via 10-Hz GPS. Distance covered >14.4 km.h(-1) (D>14.4 km·h(-1)) and >80% of vYo-YoIR1 (D>80%vYo-YoIR1) were examined. Upon arrival at altitude, there was a greater decrement in vYo-YoIR1 (Cohen's d +1.0, 90%CL ± 0.8) and D>14.4 km·h(-1) (+0.5 ± 0.8) in AUS. D>14.4 km.h(-1) was similarly reduced relative to vYo-YoIR1 in both groups, so that D>80%vYo-YoIR1 remained similarly unchanged (-0.1 ± 0.8). Throughout the altitude sojourn, vYo-YoIR1 and D>14.4 km·h(-1) increased in parallel in AUS, so that D>80%vYo-YoIR1 remained stable in AUS (+6.0%/match, 90%CL ± 6.7); conversely D>80%vYo-YoIR1 decreased largely in BOL (-12.2%/match ± 6.2). In sea-level natives competing at high-altitude, changes in match running performance likely follow those in high-intensity running performance. Bolivian data confirm that increases in 'fitness' do not necessarily translate into greater match running performance, but rather in reduced relative exercise intensity. Key pointsWhen playing at high-altitude, players may alter their activities during matches in relation to their transient maximal physical capacities, possibly to maintain a 'tolerable' relative exercise intensity.While there is no doubt that running performance per se in not the main determinant of match outcomes (Carling, 2013), fitness levels influence relative match intensity (Buchheit et al., 2012, Mendez-Villanueva et al., 2013), which in-turn may impact on decision making and skill performance (Rampinini et al., 2008).In the context of

Analysis of the perovskite structure LaxSr1-xCryMn1-yO3-δ with potential application as an anode for solid oxide fuel cells

Energy Technology Data Exchange (ETDEWEB)

Alvarado Flores, J.J.

2017-07-01

Solid oxide fuel cells (SOFC) are complex devices that offer great advantages over conventional manner in which electrical energy is produced. Many of these advantages revolve around the environmental impact and particularly energy efficiency. However, progress in the field of these devices operating at high temperatures require the continuous search for new materials with advanced properties, optimization in manufacturing, cutting edge technologies for the processing of its main components (anode-electrolyte-cathode-seal) and low manufacturing costs. Here, the perovskite structure material LaxSr1-xCryMn1-yO3-δ (LSCM) is efficient, stable redox environments, has low manufacturing cost and is optimized for SOFC applications. Its properties compare favorably with the compound Ni/YSZ using hydrogen as a fuel; and when methane is used, it requires only 3% moisture to prevent carbon formation, which is much lower compared to when used Ni/YSZ (50% moisture). The LSCM material allows a SOFC cell operate at intermediate temperatures around 700°C. This article provides a brief review of the excellent properties and potential presented by this perovskite.

Most existing evidence-based sexual health interventions focus on individual-level behavior, even though there is substantial evidence that highlights the influential role of social environments in shaping adolescents' behaviors and reproductive health outcomes. We developed Yo Puedo, a combined conditional cash transfer and life skills intervention for youth to promote educational attainment, job training, and reproductive health wellness that we then evaluated for feasibility among 162 youth aged 16-21 years in a predominantly Latino community in San Francisco, CA. The intervention targeted youth's social networks and involved recruitment and randomization of small social network clusters. In this paper we describe the design of the feasibility study and report participants' baseline characteristics. Furthermore, we examined the sample and design implications of recruiting social network clusters as the unit of randomization. Baseline data provide evidence that we successfully enrolled high risk youth using a social network recruitment approach in community and school-based settings. Nearly all participants (95%) were high risk for adverse educational and reproductive health outcomes based on multiple measures of low socioeconomic status (81%) and/or reported high risk behaviors (e.g., gang affiliation, past pregnancy, recent unprotected sex, frequent substance use; 62%). We achieved variability in the study sample through heterogeneity in recruitment of the index participants, whereas the individuals within the small social networks of close friends demonstrated substantial homogeneity across sociodemographic and risk profile characteristics. Social networks recruitment was feasible and yielded a sample of high risk youth willing to enroll in a randomized study to evaluate a novel sexual health intervention.

This study was designed to assess the effects of Ramadan fasting on the profile of mood state and perceived exertion in young soccer players and aerobic and anaerobic performances during the Yo-Yo, repeated sprint ability (RSA) and the Wingate tests. Twenty junior male soccer players completed the Yo-Yo, the RSA, and the Wingate tests on three different occasions: one-week before Ramadan (BR), the second week (SWR) and the fourth week (ER) of Ramadan. The total distance (TD) covered and the estimated maximal aerobic velocity (MAV) during the Yo-Yo test were recorded. During the RSA test, peak power (PP) during each sprint, the percentage of decrement of PP (PD) and total work (Wtotal) were calculated. During the Wingate test, peak (P(peak)) and mean (P(mean)) powers and fatigue index (FI) were recorded. TD and MAV (P=0.01) during the Yo-Yo test and PP (P=0.01, P=0.004, P=0.001, P=0.01, P=0.03 for sprints 1, 2, 3, 4, and 5, respectively) and Wtotal (P=0.02) during the RSA test were significantly higher during BR than ER. Furthermore, muscle fatigue during the RSA test increased significantly from BR to ER (P=0.01). P(peak) and P(mean) during the Wingate test decreased significantly from BR to SWR and ER (PRamadan in comparison with BR. The present study suggests that both aerobic and anaerobic performances during the Yo-Yo, the RSA and the Wingate tests were affected by Ramadan fasting in young soccer players.

Full Text Available The aim of this study was to analyze whether the heart rate variability (HRV, assessed at the beginning of a soccer preseason, reveals a correlation with the improvement of physical performance over this training period. Ten soccer players took part in the study. Their performance was evaluated by the following tests: the Yo-Yo intermittent recovery test, Level 1(Yo-Yo IR1; the 30-m sprint time, and the vertical jump; all were conducted before and after six weeks of pre-season. The HRV measurements were performed at rest in the supine position for ten minutes. The Spearman Rank Correlation test was used to investigate any possible relationship between HRV and improvements in performance, while the Student’s t-test verified the changes in both performance and HRV. The Magnitude-Based Inferences approach (qualitative analysis was applied to verify the possibilities of the observed values being positive, negative or inconclusive. There were significant improvements in Yo-Yo IR1 performance (P< 0.001 and in the 30-m sprint time (P< 0.001. The qualitative analysis revealed that the differences in Yo-Yo IR1 performance were very likely positive, were almost certainly positive for the sprint, but were inconclusive for the vertical jump. There was a strong correlation between one parasympathetic index and the change in performance [r = 0.85 P = 0.003 (IC95% = 0.49 – 0.97]. In conclusion, this study revealed a strong correlation between parasympathetic indices of HRV (analyzed before the training with the performance improvement in Yo-Yo IR1 in football athletes during pre-season.

Thirty-six (male, n=14, female n=22 young basketball players (age 16.0±0.9 yrs performed the RSM, RSA, Yo-Yo IR1, SJ and CMJ, and were re-tested only for RSM and RSA after one week. The absolute error of reliability (standard error of the measurement was lower than 0.212-s and 0.617-s for the time variables of the RSA and RSM test, respectively. Performance in the RSA and RSM test significantly correlated with CMJ and SJ. The best time, worst time and total time of the RSA and RSM test were negatively correlated with Yo-Yo IR1 distance. Based on these findings, consistent with previously published studies, it was concluded that the novel RSM test was valid and reliable.

J Strength Cond Res 30(11): 3066-3072, 2016-Elite women volleyball players (n = 25; mean ± SD: age, 19 ± 5 years; height, 171 ± 7 cm; weight, 63 ± 10 kg) volunteered to participate in the study. They were randomized into a high-intensity training (HIT; n = 13) group and a control (CON; n = 12) group. In addition to the normal team training and games, HIT performed 6-10 × 30-seconds all-out running intervals separated by 3-minute recovery periods 3 times per week during a 4-week in-season period whereas CON only completed the team training sessions and games. Preintervention and postintervention, all players completed the arrowhead agility test (AAT), a repeated sprint test (RST; 5 × 30 meters separated by 25 seconds of recovery), and the Yo-Yo Intermittent Recovery level 2 test (Yo-Yo IR2) followed by a-10 minute rest period and the Yo-Yo IR1 test. Mean running distance during HIT in week 1 was 152 ± 4 m and increased (p ≤ 0.05) by 4.6% (159 ± 3 m) in week 4. The AAT performance improved (p ≤ 0.05) by 2.3% (18.87 ± 0.97-18.44 ± 1.06 seconds) and RST by 4.3% postintervention in the HIT group only. Baseline RST fatigue index was 7.0 ± 2.9 and 6.2 ± 5.0% in HIT and CON, respectively, but was lowered (p ≤ 0.05) to 2.7 ± 3.0% posttraining in HIT and remained unaltered in CON (5.5 ± 5.0%). In HIT, Yo-Yo IR2 and Yo-Yo IR1 performance improved by 12.6 and 18.3% postintervention, respectively, with greater (p ≤ 0.05) Yo-yo IR1 change scores than in CON. In conclusion, additional high-intensity in-season training performed as interval running improved agility, repeated sprint ability, and high-intensity intermittent exercise performance in elite women volleyball players.

J Strength Cond Res 32(3): 790-797, 2018-The aim of this study was to compare the session rating of perceived exertion training load (sRPE-TL), training volume (TV), and the changes in physical fitness between professional (n = 14) and semiprofessional (n = 18) basketball players during the preparation period. Furthermore, relationships between sRPE-TL and TV with changes in physical fitness level were investigated. The players performed the Yo-Yo intermittent recovery test-level 1 (Yo-Yo IR1) before and after the preparation period. In addition, physiological responses to a standardized 6-minute continuous running test (Mognoni's test) and to a standardized 5-minute high-intensity intermittent running test (HIT) were measured. Session rating of perceived exertion-TL and TV were greater for professional (5,241 ± 1787 AU; 914 ± 122 minutes) compared with semiprofessional players (2,408 ± 487 AU; 583 ± 65 minutes). Despite these differences, Yo-Yo IR1 performance improvements (∼30%) and physiological adaptations to the Mognoni's test were similar between the 2 groups. Furthermore, physiological adaptations to HIT were slightly greater for professional compared with semiprofessional players; however, the magnitude of these effects was only small/moderate. No clear relationships were found between sRPE-TL and changes in Yo-Yo IR1 performance and Mognoni's test (rs ± 90% confidence interval [CI]: Yo-Yo IR1, 0.18 ± 0.30; Mognoni's test, -0.14 ± 0.29). Only moderate relationships were found between sRPE-TL and changes in HIT (rs ± 90% CI: [La], -0.48 ± 0.23; [H], -0.42 ± 0.25). These results raise doubts on the effectiveness of using high sRPE-TL and TV during the preparation period to improve the physical fitness level of players. The Yo-Yo IR1 seems to be sensitive to

Anthropometric characteristics, physical fitness and technical skills of under-19 (U19) soccer players were compared by competitive level (elite, n=95; non-elite, n=85) and playing position (goalkeeper, central defender, fullback, midfield, forward). Fitness tests included 5- and 30-m sprints......, agility, squat jump (SJ) and countermovement jump (CMJ), strength and Yo-Yo intermittent endurance test level 2 (Yo-Yo IE2). Soccer-specific skills included ball control and dribbling. Independent of position, elite players presented more hours of training per year than non-elite players (d>1.2). Stature...... and body mass discriminated elite from non-elite players among goalkeepers and central defenders (d>0.6). Major differences were noted between elite and non-elite goalkeepers for SJ, CMJ, Yo-Yo IE2, and ball control (d>1.2).

Objectives To examine the time course of wellness, fatigue and performance during an altitude training camp (La Paz, 3600 m) in two groups of either sea-level (Australian) or altitude (Bolivian) native young soccer players. Methods Wellness and fatigue were assessed using questionnaires and resting heart rate (HR) and HR variability. Physical performance was assessed using HR responses to a submaximal run, a Yo-Yo Intermittent recovery test level 1 (Yo-YoIR1) and a 20 m sprint. Most measures were performed daily, with the exception of Yo-YoIR1 and 20 m sprints, which were performed near sea level and on days 3 and 10 at altitude. Results Compared with near sea level, Australians had moderate-to-large impairments in wellness and Yo-YoIR1 relative to the Bolivians on arrival at altitude. The acclimatisation of most measures to altitude was substantially slower in Australians than Bolivians, with only Bolivians reaching near sea-level baseline high-intensity running by the end of the camp. Both teams had moderately impaired 20 m sprinting at the end of the camp. Exercise HR had large associations (r>0.5–0.7) with changes in Yo-YoIR1 in both groups. Conclusions Despite partial physiological and perceptual acclimatisation, 2 weeks is insufficient for restoration of physical performance in young sea-level native soccer players. Because of the possible decrement in 20 m sprint time, a greater emphasis on speed training may be required during and after altitude training. The specific time course of restoration for each variable suggests that they measure different aspects of acclimatisation to 3600 m; they should therefore be used in combination to assess adaptation to altitude.

Several investigators have reported the effects of reduced training and interrupted training on athletic performance, but few reports are available for soccer players. The purpose of this study was to examine, using the Yo-Yo intermittent recovery level 2 (YoYoIR2) test and sprint performance, the effects on soccer players of a reduced training program consisting of either moderate running training, plyometric training. After the completion of a competitive season, 29 male soccer players were divided into 3 groups: the running group (n = 13), the plyometric group (n = 11), and the control group (n = 5). Both training groups completed either running or plyometric training sessions 2 d·wk(-1) for 3 weeks, whereas the control group was not allowed to perform any training. The subjects performed YoYoIR2 and 20-m sprint tests before (pre) and after (post) the experimental period. Neither training group showed any significant training effects on the YoYoIR2 performance or 20-m sprint times compared with the control group. This study suggests that neither endurance running nor plyometric training 2 d·wk(-1) for 3 weeks has a significant effect on high-intensity performance compared with a nontraining regimen. However, our results do not support complete inactivity. These results may have important implications for the management of training cessation for a few weeks.

Full Text Available We used Helix pomatia and Helix aspersa species and measure their growth as the snails were approaching the hibernation season. Helix pomatia 2yo shown a decrease in weight while being raised in enclosed parcels of 4sqm the younger Helix pomatia 1yo as well as Helix aspersa Muller demonstrated the ability to adapt relatively fast to the same conditions. We established 5 experimental lots in a Helix pomatia farm, GPS coordinates N46.606040 E23.599950. Control lot contained Taraxacum officinales, Sonchus oleraceus, Equisetum arvense and Atriplex hortensis, wild flora found within the farm. The other lots contained the same plants as the control lot plus different combinations of imported plants from other areals. The H. pomatia 2yo weight decreased in the control lot by a mean of -3.86% while H. aspersa 1yo marked an increase of +16.89% in the same lot during the same period. The lot containing lupinus polyphyllus delivered snails with weight gain of +24.66% for H. pomatia 2yo and an increase of only +1.98% for H. aspersa 1yo. As a contrast, H. pomatia 2yo gained only +7.72% while H. aspersa 1yo gained +28.89%, in the lot containing Lavanda officinalis, Foeniculum vulgare and Hyssopus officinalis among the other plants.

To investigate the effects of mental fatigue on soccer-specific physical and technical performance. This investigation consisted of two separate studies. Study 1 assessed the soccer-specific physical performance of 12 moderately trained soccer players using the Yo-Yo Intermittent Recovery Test, Level 1 (Yo-Yo IR1). Study 2 assessed the soccer-specific technical performance of 14 experienced soccer players using the Loughborough Soccer Passing and Shooting Tests (LSPT, LSST). Each test was performed on two occasions and preceded, in a randomized, counterbalanced order, by 30 min of the Stroop task (mentally fatiguing treatment) or 30 min of reading magazines (control treatment). Subjective ratings of mental fatigue were measured before and after treatment, and mental effort and motivation were measured after treatment. Distance run, heart rate, and ratings of perceived exertion were recorded during the Yo-Yo IR1. LSPT performance time was calculated as original time plus penalty time. LSST performance was assessed using shot speed, shot accuracy, and shot sequence time. Subjective ratings of mental fatigue and effort were higher after the Stroop task in both studies (P motivation was similar between conditions. This mental fatigue significantly reduced running distance in the Yo-Yo IR1 (P performance time were not different between conditions; however, penalty time significantly increased in the mental fatigue condition (P = 0.015). Mental fatigue also impaired shot speed (P = 0.024) and accuracy (P performance.

Dolan, P, Witherbee, KE, Peterson, KM, and Kerksick, CM. Effect of carbohydrate, caffeine, and carbohydrate + caffeine mouth rinsing on intermittent running performance in collegiate male lacrosse athletes. J Strength Cond Res 31(9): 2473-2479, 2017-Recently, an interest has developed in the potential to rinse the oral cavity with key nutrients to impact various types of exercise and presumably sporting performance. Although multiple studies examining carbohydrate mouth rinsing have been completed, conflicting evidence surrounding caffeine mouth rinsing persists, and no research has explored its ability to impact high-intensity, intermittent running performance. This study investigated the independent and synergistic ability of carbohydrate and caffeine mouth rinsing to improve intermittent running performance. The Yo-Yo Intermittent Recovery Test-Level 1 (Yo-Yo Level 1) was completed in 10 collegiate (National Collegiate Athletic Association [NCAA] Division II) male lacrosse players after a 10-second mouth rinse with a solution of either carbohydrate (CHO), caffeine (CAF), carbohydrate + caffeine (CHO + CAF), placebo (H2O), or a no rinse control (CON). No significant improvements in Yo-Yo IRT-1 performance were found (p > 0.05). Perceptual indications of effort (i.e., rating of their perceived exertion [RPE]) were significantly lower (p ≤ 0.05) in CHO and CHO + CAF when compared with CON after speed level 11. Interestingly, RPE levels were nonsignificantly lower in all but one level of the Yo-Yo Level 1 for CHO in comparison with other groups. Carbohydrate and caffeine mouth rinsing seems to exert no impact on running performance before maximal intermittent running in a group of male collegiate lacrosse players.

The purpose of this study was to determine whether caffeinated gum influenced performance in a battery of soccer-specific tests used in the assessment of performance in soccer players. In a double blind, randomised, cross-over design, ten male university-standard soccer players (age 19 ± 1 y, stature 1.80 ± 0.10 m, body mass 75.5 ± 4.8 kg) masticated a caffeinated (200 mg; caffeine) or control (0 mg; placebo) gum on two separate occasions. After a standardised warm-up, gum was chewed for 5 min and subsequently expectorated 5 min before players performed a maximal countermovement jump, a 20 m sprint test and the Yo-Yo intermittent recovery test level 1 (Yo-YoIR1). Performance on 20 m sprints were not different between trials (caffeine: 3.2 ± 0.3 s, placebo: 3.1 ± 0.3 s; p = 0.567; small effect size: d = 0.33), but caffeine did allow players to cover 2.0% more distance during Yo-YoIR1 (caffeine: 1754 ± 156 m, placebo: 1719 ± 139 m; p = 0.016; small effect size: d = 0.24) and increase maximal countermovement jump height by 2.2% (caffeine: 47.1 ± 3.4 cm, placebo: 46.1 ± 3.2 cm; p = 0.008; small effect size: d = 0.30). Performance on selected physical tests (Yo-YoIR1 and countermovement jump) was improved by the chewing of caffeinated gum in the immediate period before testing in university-standard soccer players but the sizes of such effects were small. Such findings may have implications for the recommendations made to soccer players about to engage with subsequent exercise performance.

Forty-five players from 3 national basketball teams (Under-18 years, Under-20 years, and Senior) were measured for anthropometry (height, body mass, percentage body fat), explosive power (5 jumps and vertical jump), speed (5-m, 10-m, and 30-m sprint), agility (T-test), strength (bench press and squat 1 repetition maximum [1RM]), and intermittent high-intensity endurance performance (Yo-Yo intermittent recovery test [Yo-Yo IR1]). Data on match frequency, training routines, and playing experience were also collected. Under-18 players were significantly (p agility (p Under-20 > Under-18, p agility and 5- and 10-m performances. Power forwards and centers were stronger than the rest of players' positions in the bench press 1RM (p basketball. Differences were particularly evident in intermittent high-intensity endurance and agility performance. Sprint training possibly should be individualized when dealing with positional roles in elite men's basketball. Strength and conditioning coaches should use Yo-Yo IR1 to assess specific endurance in players of different age and positional role.

2016-01-01

In order to determine whether small-sided game (SSG) locomotor performance can serve as a fitness indicator, we (1) compared 6-a-side (6v6) SSG-intensity of players varying in fitness and skill, (2) examined the relationship of the 6v6-SSG and Yo-Yo IR2 and (3) assessed the reliability of the 6v6-SSG. Thirty-three professional senior, 30 professional youth, 62 amateur and 16 professional woman football players performed 4 × 7 min 6v6-SSGs recorded by a Local Position Measurement system. A substantial subgroup (N = 113) also performed the Yo-Yo IR2. Forty-seven amateur players performed two or three 6v6-SSGs. No differences in 6v6-SSG time-motion variables were found between professional senior and professional youth players. Amateurs showed lower values than professional seniors on almost all time-motion variables (ES = 0.59-1.19). Women displayed lower high-intensity time-motion variables than all other subgroups. Total distance run during 6v6-SSG was only moderately related to Yo-Yo IR2 distance (r = 0.45), but estimated metabolic power, high speed (>14.4 km · h(-1)), high acceleration (>2 m · s(-2)), high power (>20 W · kg(-1)) and very high (35 W · kg(-1)) power showed higher correlations (r = 0.59-0.70) with Yo-Yo IR2 distance. Intraclass correlation coefficient values were higher for total distance (0.84) than other time-motion variables (0.74‒0.78). Although total distance and metabolic power during 6v6-SSG showed good reproducibility (coefficient of variation (CV) < 5%), CV was higher (8-14%) for all high-intensity time-motion variables. It was therefore concluded that standardised SSG locomotor performance cannot serve used as a valid and reliable fitness indicator for individual players.

To investigate the relationship between physical qualities and match activity profiles of recreational Australian football players. Prospective cohort study. Forty players from three recreational Australian football teams (Division One, Two and Three) underwent a battery of fitness tests (vertical jump, 10 and 40 m sprint, 6 m × 30 m repeated sprint test, Yo-Yo intermittent recovery level Two and 2-km time trial). The activity profiles of competitive match-play were quantified using 10-Hz Global Positioning System units. Division One players possessed greater maximum velocity, Yo-Yo level Two and 2-km time trial performances than Division Two and Three players. In addition, Division One players covered greater relative distance, and relative distances at moderate- and high-intensities during match-play than Division Two and Three players. Division Two players had better 2-km time trial performances than Division Three players. Positive associations (P football players competing at a higher level exhibit greater physical qualities and match-play activity profiles than lesser-skilled recreational players. Acceleration and maximum velocity, 2-km time trial and Yo-Yo level Two performances discriminate between players of different playing levels, and are related to physical match performance in recreational Australian football. The development of these qualities is likely to contribute to improved match performance in recreational Australian football players. Copyright © 2014 Sports Medicine Australia.

Full Text Available La literatura y el viaje, como todo el mundo reconoce, nacen juntos como experiencia y mirada hacia el otro. La temática del viaje, entonces, es una de las características de la literatura en general y más en la literatura hispanoamericana que considera precisamente el Diario de viaje de Cristóbal Colón como uno de sus textos fundadores asimismo como las Crónicas de Indias. Se trata de un género fronterizo que levanta un conjunto de cuestionamientos y cuyo hibridismo, como escribe Biagio D’Angelo (2009: 11, 14 «amplía las fronteras imaginadas de la ficción literaria. [...] El viaje desconcierta, desestabiliza y hace temblar la identidad de cada sujeto. Nos mudamos en nosotros mismos a través de otro(s». En esta ocasión se propone el estudio de La Habana (1844, un libro de viaje, escrito por la Condesa de Merlin (La Habana, 1789 – París, 1853 y la reescritura de un cuento de hadas «Si esto es la vida, yo soy Caperucita Roja» de Luisa Valenzuela (Buenos Aires, 1938, que pertenece a la colección «Cuentos de hades», publicada en Simetrías (1993. Al estudiar las características de este género, muy distinto en los dos siglos considerados, se observa la importancia del tiempo como elemento que acompaña la perspectiva sentimental y existencial que caracteriza el punto de vista de ambas autoras.

The anti-inflammatory mechanisms of low-fat dairy product consumption are largely unknown. The objective of this study was to determine whether low-fat yogurt reduces biomarkers of chronic inflammation and endotoxin exposure in women. Premenopausal women (BMI 18·5-27 and 30-40 kg/m2) were randomised to consume 339 g of low-fat yogurt (yogurt non-obese (YN); yogurt obese (YO)) or 324 g of soya pudding (control non-obese; control obese (CO)) daily for 9 weeks (n 30/group). Fasting blood samples were analysed for IL-6, TNF-α/soluble TNF II (sTNF-RII), high-sensitivity C-reactive protein, 2-arachidonoyl glycerol, anandamide, monocyte gene expression, soluble CD14 (sCD14), lipopolysaccharide (LPS), LPS binding protein (LBP), IgM endotoxin-core antibody (IgM EndoCAb), and zonulin. BMI, waist circumference and blood pressure were also determined. After 9-week yogurt consumption, YO and YN had decreased TNF-α/sTNFR-RII. Yogurt consumption increased plasma IgM EndoCAb regardless of obesity status. sCD14 was not affected by diet, but LBP/sCD14 was lowered by yogurt consumption in both YN and YO. Yogurt intervention increased plasma 2-arachidonoylglycerol in YO but not YN. YO peripheral blood mononuclear cells expression of NF-κB inhibitor α and transforming growth factor β1 increased relative to CO at 9 weeks. Other biomarkers were unchanged by diet. CO and YO gained approximately 0·9 kg in body weight. YO had 3·6 % lower diastolic blood pressure at week 3. Low-fat yogurt for 9 weeks reduced biomarkers of chronic inflammation and endotoxin exposure in premenopausal women compared with a non-dairy control food. This trial was registered as NCT01686204.

Full Text Available UNLABELLED: Restricted sleep duration among young adults and adolescents has been shown to increase the risk of morbidities such as obesity, diabetes or accidents. However there are few epidemiological studies on normal total sleep time (TST in representative groups of teen-agers which allow to get normative data. PURPOSE: To explore perceived total sleep time on schooldays (TSTS and non schooldays (TSTN and the prevalence of sleep initiating insomnia among a nationally representative sample of teenagers. METHODS: Data from 9,251 children aged 11 to 15 years-old, 50.7% of which were boys, as part of the cross-national study 2011 HBSC were analyzed. Self-completion questionnaires were administered in classrooms. An estimate of TSTS and TSTN (week-ends and vacations was calculated based on specifically designed sleep habits report. Sleep deprivation was estimated by a TSTN - TSTS difference >2 hours. Sleep initiating nsomnia was assessed according to International classification of sleep disorders (ICSD 2. Children who reported sleeping 7 hours or less per night were considered as short sleepers. RESULTS: A serious drop of TST was observed between 11 yo and 15 yo, both during the schooldays (9 hours 26 minutes vs. 7 h 55 min.; p<0.001 and at a lesser extent during week-ends (10 h 17 min. vs. 9 h 44 min.; p<0.001. Sleep deprivation concerned 16.0% of chidren aged of 11 yo vs. 40.5% of those of 15 yo (p<0.001. Too short sleep was reported by 2.6% of the 11 yo vs. 24.6% of the 15 yo (p<0.001. CONCLUSION: Despite the obvious need for sleep in adolescence, TST drastically decreases with age among children from 11 to 15 yo which creates significant sleep debt increasing with age.

Imaging of dopaminergic function is useful in the investigation of patients with Parkinson disease (iPD) and other extrapyramidal diseases. Using agents that bind to dopamine transporters ([{sup 123}I]{beta}-CIT) and receptors ([{sup 123}I]IBF SPECT), we investigated SPECT in 9 healthy volunteers and 24 patients for dopamine transporters as well as 15 patients for dopamine receptors. In {beta}-CIT SPECT studies, we examined 17 iPD patients (63.3{+-}9.9 y/o), 3 multiple system atrophy (MSA) patients (olivopontocerebellar atrophy (OPCA) type) (64.0{+-}8.0 y/o), 2 vascular parkinsonism (VP) patients (71.0{+-}0.0 y/o), 1 progressive supranuclear palsy (PSP) patient (69 y/o), 1 cortico-basal degeneration (CBD) patient (50 y/o) and nine healthy controls (39.1{+-}9.3 y/o). For IBF SPECT studies 11 iPD patients (60.6{+-}10.9 y/o), 3 MSA patients (2 OPCA type (50.5{+-}3.5 y/o) and 1 striatonigral degeneration (SND) type (65 y/o)) and 1 PSP patient (60 y/o) underwent SPECT scans after the injection of [{sup 123}I]IBF. The specific to nonspecific striatal ratio (St/Oc-1), ratio of putaminal uptake to caudatal uptake (Pu/Ca), and asymmetry indices (AI) were estimated. {beta}-CIT studies showed ST/Oc-1 as follows; iPD: 2.66{+-}1.09 (n=17), VP: 5.73 and 7.39, MSA: 1.84{+-}0.46 (n=3), PSP: 2.34, CBD: 2.16. In all extrapyramidal diseases except VP, St/Oc-1 ratios were significantly lower than those in normal volunteers (6.46{+-}1.08) (p<0.01). Also in early-phase iPD patients (Yahr I-II), St/Oc-1 (3.16{+-}1.49: n=4) was significantly lower than those in normal volunteers (p<0.01). In IBF studies, St/Oc-1 ratios were significantly higher in early-phase (Yahr I-II) iPD patients (1.82{+-}0.25: n=5) than those in late-phase (Yahr III-IV) iPD patients (1.38{+-}0.32: n=6) (p<0.05). The Pu/Ca ratios in iPD patients (1.12{+-}0.13) and MSA (OPCA type) patients (0.95{+-}0.05) were higher than that in MSA (SND type) patient (0.78) and were lower than that in PSP patient (1.55).

Sodium bicarbonate intake has been shown to improve exercise tolerance, but the effects on high-intensity intermittent exercise are less clear. Thus, the aim of the present study was to determine the effect of sodium bicarbonate intake on Yo-Yo intermittent recovery test level 2 performance in trained young men. Thirteen men aged 23 ± 1 year (height: 180 ± 2 cm, weight: 78 ± 3 kg; VO2max: 61.3 ± 3.3 mlO2 · kg(-1) · min(-1); means ± SEM) performed the Yo-Yo intermittent recovery test level 2 (Yo-Yo IR2) on two separate occasions in randomized order with (SBC) and without (CON) prior intake of sodium bicarbonate (0.4 g · kg(-1) body weight). Heart rate and rating of perceived exertion (RPE) were measured during the test and venous blood samples were taken frequently. Yo-Yo IR2 performance was 14 % higher (P = 0.04) in SBC than in CON (735 ± 61 vs 646 ± 46 m, respectively). Blood pH and bicarbonate were similar between trials at baseline, but higher (P = 0.003) immediately prior to the Yo-Yo IR2 test in SBC than in CON (7.44 ± 0.01 vs 7.32 ± 0.01 and 33.7 ± 3.2 vs 27.3 ± 0.6 mmol · l(-1), respectively). Blood lactate was 0.9 ± 0.1 and 0.8 ± 0.1 mmol · l(-1) at baseline and increased to 11.3 ± 1.4 and 9.4 ± 0.8 mmol · l(-1) at exhaustion in SBC and CON, respectively, being higher (P = 0.03) in SBC. Additionally, peak blood lactate was higher (P = 0.02) in SBC than in CON (11.7 ± 1.2 vs 10.2 ± 0.7 mmol · l(-1)). Blood glucose, plasma K(+) and Na(+) were not different between trials. Peak heart rate reached at exhaustion was 197 ± 3 and 195 ± 3 bpm in SBC and CON, respectively, with no difference between conditions. RPE was 7% lower (P = 0.003) in SBC than in CON after 440 m, but similar at exhaustion (19.3 ± 0.2 and 19.5 ± 0.2). In conclusion, high-intensity intermittent exercise performance is improved by prior

The aim of this study was to compare backs and forwards rugby union players recruited to a National team in the following physical and physiological indicators: anthropometrics, squat jump (SJ), countermovement jump (CMJ), 10- and 30-meter sprint, resting heart rate variability (HRV), Yo-Yo Test and heart rate (HR) at 2 minutes of test. The measurements were performed on the first day of a training camp planned to finely select the players who would participate in the 2016 America's Rugby Championship. The magnitude-based inference was used in the comparisons. Backs demonstrated almost certainly greater distance in the Yo-Yo Test (backs: 2305.9±231.3 meters; forwards: 1802.4±361.2 meters), higher vertical jump height in both SJ and CMJ (SJ: 44.0±5.3 cm vs. 37.6±5.4 cm; CMJ: 46.1±5.0 cm vs. 40.0±5.5 cm, for backs and forwards respectively), and superior sprint velocity in 10- and 30-m (10-m: 6.02±0.23 m.s-1 vs. 5.51±0.34 m.s-1; 30-m: 7.46±0.25 m.s-1 vs. 6.89±0.37 m.s-1, for backs and forwards respectively) than the forwards. In contrast, forwards were almost certainly taller and heavier than backs, and displayed higher sprint momentum in 10- and 30-meters (10 meters: 513.0±51.6 kg.m.s-1 vs. 598.4±53.1 kg.m.s-1; 30 meters: 635.3±56.1 kg.m.s-1 vs. 749.0±70.5 kg.m.s-1, for backs and forwards respectively). The submaximal HR in the first 2-minutes of the Yo-Yo test was likely lower in the backs than in the forwards (77.6±5.1% of the maximal HR vs. 81.3±5.4% of the maximal HR for backs and forwards respectively), while HRV indices were not different between backs and forwards. Playing position appears to be determined by the players' physical and physiological characteristics in top-level rugby union, and the submaximal HR measured during Yo-Yo test can be a simple alternative to discriminate backs and forwards.

The aim of this study was to examine the effects of a 5-week training program, consisting of repeated 30-m sprints, on two repeated sprint ability (RSA) test formats: one with one change of direction (RSA) and the other with multiple changes of direction (RSM). Thirty-six young male and female basketball players (age 16.1 ± 0.9 years), divided into two experimental groups, were tested for RSA, RSM, squat jump, counter-movement jump, and the Yo-Yo Intermittent Recovery-Level-1 (Yo-Yo IR1) test, before and after a 4-week training program and 1 week of tapering. One group performed 30-m sprints with one change of direction (RSA group, RSAG), whereas the other group performed multidirectional 30-m sprints (RSM group, RSMG). Both groups improved in all scores in the post-intervention measurements (P basketball players, but have a different psycho-physiological impact.

The aim of this study was to compare the effects of 6 weeks of vertical, horizontal, or combined vertical and horizontal plyometric training on muscle explosive, endurance, and balance performance. Forty young soccer players aged between 10 and 14 years were randomly divided into control (CG; n = 10), vertical plyometric group (VG; n = 10), horizontal plyometric group (HG; n = 10), and combined vertical and horizontal plyometric group (VHG; n = 10). Players performance in the vertical and horizontal countermovement jump with arms, 5 multiple bounds test (MB5), 20-cm drop jump reactive strength index (RSI20), maximal kicking velocity (MKV), sprint, change of direction speed (CODS), Yo-Yo intermittent recovery level 1 test (Yo-Yo IR1), and balance was measured. No significant or meaningful changes in the CG, apart from small change in the Yo-Yo IR1, were observed while all training programs resulted in meaningful changes in explosive, endurance, and balance performance. However, only VHG showed a statistically significant (p ≤ 0.05) increase in all performance test and most meaningful training effect difference with the CG across tests. Although no significant differences in performance changes were observed between experimental groups, the VHG program was more effective compared with VG (i.e., jumps, MKV, sprint, CODS, and balance performance) and HG (i.e., sprint, CODS, and balance performance) to small effect. The study demonstrated that vertical, horizontal, and combined vertical and horizontal jumps induced meaningful improvement in explosive actions, balance, and intermittent endurance capacity. However, combining vertical and horizontal drills seems more advantageous to induce greater performance improvements.

Rare earth sesquioxides like Y2O3 are known as widegap insulators with the highly stable closed shell trivalent rare earth ions. On the other hand, rare earth monoxides such as YO have been recognized as gaseous phase, and only EuO and YbO were thermodynamically stable solid-phase rock salt monoxides. In this study, solid-phase rock salt yttrium monoxide, YO, was synthesized in a form of epitaxial thin film by pulsed laser deposition method. YO possesses unusual valence of Y2+ ([Kr] 4d1) . In contrast with Y2O3, YO was narrow gap semiconductor with dark-brown color. The electrical conductivity was tunable from 10-1 to 103 Ω-1 cm-1 by introducing oxygen vacancies as electron donor. Weak antilocalization behavior was observed indicating significant spin-orbit coupling owing to 4 d electron carrier. The absorption spectral shape implies the Mott-Hubbard insulator character of YO. Rare earth monoixdes will be new platform of functional oxides.

Cope, C; Ginsberg, G G

2001-06-01

Our aim was to evaluate the efficacy of a prototype "YO-YO"-shaped covered stent for keeping experimental magnetic compression gastroenteric fistulas patent for 6 months. Magnets were introduced perorally with endoscopic and fluoroscopic guidance and were mated across the gastric and jejunal walls of 5 dogs. After a mean of 5.5 days a 12-mm diameter YO-YO stent was placed perorally in the resulting fistula. The gastroenteric anastomosis (GEA) with stent was observed endoscopically and gastrographically at 1- to 2-month intervals. There was no morbidity and there were no significant weight changes. The GEA was widely patent at necropsy at 6 months (n = 4); partial membrane separation occurred at 5 months in the fifth dog. There was minor breakage of the stent prongs in 2 animals. Peroral creation of a stented magnetic compression GEA is safe and provides long-term patency. This technique may be potentially useful for managing gastric outlet obstruction caused by malignancy.

Intermittent Testing and Training for High-Level Football Players

Football is the most popular sport in the world, played by over 400 million men and women. In addition to the wide range of sport-specific technical and tactical skills needed, several physical components have been shown to be necessary to perform at a high level. The present PhD thesis is based...... on four articles that focus on physical testing and training for elite and sub-elite football players.The first article (Study I) aims to identify and establish aerobic capacities and anthropometric characteristics of elite female football players with the use of laboratory tests, and to examine whether...... systematic differences between the playing positions can be detected. Lately, field tests have become more frequently used in football than the laboratory tests used in Study I.

This study aimed at comparing the effects of intermittent and repeated sprint ability training on physiological variables. Sixteen young female basketball players were randomly allocated to intermittent training (IT=8) or repeated sprint ability training (RST=8) groups. The following outcomes were measured at baseline and after 6 weeks of training: Yo-Yo intermittent recovery (Yo-Yo) and repeated sprint ability (RSA) tests. For all the variables investigated the effect of training type showed a different trend respect at current knowledge. In the RSA, best time (BT) was a significant main effect of training time (pre- vs. post-) (Ptraining type/time (P=0.03). The RST showed a decrease in BT of 3.1% (P=0.005) while the IT showed a decrease of 6.2% (Ptraining methods used in this study can be an effective training strategy for inducing anaerobic and basketball-specific training schedules. Besides, even when IT training is not done at very high speed, it can increase the maximum speed of the RSA.

The aim of the study was to develop and examine a test for evaluation of the physical and technical capacity of soccer players. Fourteen youth elite (YE) and seven sub-elite (SE) players performed a physical and technical test (PT-test) consisting of 10 long kicks interspersed with intense......(-1), and 76 +/- 11 umol L(-1) at the end of the test, respectively. After the test muscle CP, glycogen and lactate was 52.9 +/- 6.6, 354 +/- 39, and 25.3 +/- 5.9 mmol kg(-1) d.w., respectively. In summary, the PT-test can be used to evaluate a soccer player's technical skills under conditions similar...... intermittent exercise. In addition, a control test (CON-test) without intense exercise was performed. In both cases, the test result was evaluated by the precision of the 10 kicks. The players also performed the Yo-Yo intermittent recovery test level 2 (Yo-Yo IR2). For the SE-players, blood samples were...

To date, no study has compared the evolution of the foramen magnum area (FMA) and the posterior cranial fossa volume (PCFV) with the degree of cranial base synchondrosis ossification. To illustrate these features in healthy children. The FMA, the PCFV, and the ossification of 12 synchondroses according to the Madeline and Elster scale were retrospectively analyzed in 235 healthy children using millimeter slices on a computed tomography scan. The mean FMA of 6.49 cm in girls was significantly inferior to the FMA of 7.67 cm in boys (P < .001). In both sexes, the growth evolved in a 2-phase process, with a phase of rapid growth from birth to 3.75 years old (yo) followed by a phase of stabilization. In girls, the first phase was shorter (ending at 2.6 yo) than in boys (ending at 4.33 yo) and proceeded at a higher rate. PCFV was smaller in girls (P < .001) and displayed a biphasic pattern in the whole population, with a phase of rapid growth from birth to 3.58 yo followed by a phase of slow growth until 16 yo. In girls, the first phase was more active and shorter (ending at 2.67 yo) than in boys (ending at 4.5 yo). The posterior interoccipital synchondroses close first, followed by the anterior interoccipital and occipitomastoidal synchondroses, the lambdoid sutures simultaneously, then the petro-occipital and spheno-occipital synchondroses simultaneously. The data provide a chronology of synchondrosis closure. We showed that FMA and PCFV are constitutionally smaller in girls at birth (P ≤ .02) and suggest that a sex-related difference in the FMA is related to earlier closure of anterior interoccipital synchondroses in girls (P = .01).

The purpose of the study was to compare the effects of progressive volume-based overload with constant volume-based overload on muscle explosive and endurance performance adaptations during a biweekly short-term (i.e., 6 weeks) plyometric training intervention in young soccer players. Three groups of young soccer players (age 13.0 ± 2.3 years) were divided into: control (CG; n = 8) and plyometric training with (PPT; n = 8) and without (NPPT; n = 8) a progressive increase in volume (i.e., 16 jumps per leg per week, with an initial volume of 80 jumps per leg each session). Bilateral and unilateral horizontal and vertical countermovement jump with arms (CMJA), 20-cm drop jump reactive strength index (RSI20), maximal kicking velocity (MKV), 10-m sprint, change of direction speed (CODS), and Yo-Yo intermittent recovery level 1 test (Yo-Yo IR1) were measured. Although both experimental groups significantly increased CMJA, RSI20, CODS, and endurance performance, only PPT showed a significant improvement in MKV and 10-m sprint time. In addition, only PPT showed a significantly higher performance improvement in jumping, MKV, and Yo-Yo IR1 compared with CG. Also, PPT showed higher meaningful improvement compared with NPPT in all (except 1) jump performance measures. Furthermore, although PPT involved a higher total volume compared with NPPT, training efficiency (i.e., percentage change in performance/total jump volume) was similar between groups. Our results show that PPT and NPPT ensured significant improvement in muscle explosive and endurance performance measures. However, a progressive increase in plyometric training volume seems more advantageous to induce soccer-specific performance improvements.

With the lack of a cure for Alzheimer disease (AD), the identification of comorbidity is important to reduce the possibility of excess disability. Although comorbidity in patients with late-onset AD (LO-AD) is common, for people with young-onset AD (YO-AD), it is unclear how often comorbidity occurs. Furthermore, it is uncertain whether comorbidity in patients with YO-AD differs from that in patients with LO-AD. The aim of this study was to explore the prevalence, types of morbidity, and morbidity profiles in patients with YO-AD compared with those of patients with LO-AD. Explorative cohort study from 2 separate Dutch cohorts (Needs in Young-onset Dementia [NeedYD] and the Clinical Course of Cognition and Comorbidity-Dementia Study [4C-Dementia study]). Participants were recruited in 2007 and 2008 from (1) the memory clinics of 3 Dutch Alzheimer centers, (2) the memory clinics of general hospitals, (3) mental health services in the southern part of the Netherlands, and (4) young-onset dementia specialized day care facilities. A comparison group of community-dwelling, elderly patients with AD was selected from the 4C-Dementia study. Patients in this study were recruited in 2010 and 2011 from the aforementioned Alzheimer centers. The prevalence rates of comorbidity were compared between 177 patients with YO-AD and 155 patients with LO-AD. Comorbidity was classified using the International Classification of Diseases, 10th Revision (ICD-10). The total amount of comorbidity was established by counting the number of existing diseases (ICD categories or chapters) and comorbidity was also dichotomized as present or absent. Furthermore, a hierarchical cluster analysis was performed to study clusters of comorbidity. Compared with LO-AD, patients with YO-AD showed less (P < .001) overall comorbidity (58.2% vs 86.5%) and had lower prevalence rates of diabetes, obesity, and circulatory diseases; however, the prevalence rates of diseases of the nervous system in YO-AD (6

The purpose of this study was to assess the effect of a soccer match on the cardiac autonomic control of heart rate (HR) in soccer referees. Sixteen Spanish regional and third division referees (11 males: 26 ± 7 years, 74.4 ± 4.1 kg, 178 ± 3 cm, Yo-Yo IR1 ~600-1,560 m; 5 females: 22 ± 3 years, 59.3 ± 4.8 kg, 158 ± 8 cm, Yo-Yo IR1 ~200-520 m) participated with 24-h HR recordings measured with a Polar RS800 during a rest and a match day. Autonomic control of HR was assessed from HR variability (HRV) analysis. Inclusion of a soccer match (92.5% spent at >75% maximum HR) reduced pre-match (12:00-17:00 hours; small to moderate), post-match (19:00-00:00 hours; moderate to almost perfect), and night-time (00:00-05:00 hours; small to moderate) HRV. Various moderate-to-large correlations were detected between resting HRV and the rest-to-match day difference in HRV. The rest-to-match day differences of low and high-frequency bands ratio (LF/HF) and HR in the post-match period were moderately correlated with time spent at different exercise intensities. Yo-Yo IR1 performance was highly correlated with jump capacity and peak lactate, but not with any HRV parameter. These results suggest that a greater resting HRV may allow referees to tolerate stresses during a match day with referees who spent more time at higher intensities during matches exhibiting a greater LF/HF increment in the post-match period. The relationship between match activities, [Formula: see text] and HR recovery kinetics in referees and team sport athletes of different competitive levels remains to be clarified.

This study examined the effects of a 7-week in-season aerobic and high-intensity interval-training program on performance tests linked to successful handball play (e.g., repeated sprint and jumping ability). Thirty participants (age 17.0±1.2 years, body mass 81.1±3.4 kg, height 1.82±0.07 m) performed a Yo-Yo Intermittent Recovery Test level 1 (Yo-Yo IR1), a squat (SJ) and a Countermovement Jump Test (CMJ), as well as a repeated Sprint Ability Test (RSA). From this, maximal aerobic speed (MAS, reached at the end of the Yo-Yo IR1), jumping ability, best time in a single sprint trial (RSAbest), total time (RSATT) and the performance decrement (RSAdec) during all sprints were calculated. Later, subjects were randomly assigned to a control group (CG; N.=15) performing their normal training schedule (5 weekly sessions of ~90 minutes of handball training) or an experimental group (EG; N.=15). The EG performed two 30 min sessions per week of high-intensity aerobic exercises at 100-130% of MAS in addition to their normal training schedule. A significant improvement in MAS (d=4.1), RSAbest (d=1.9), RSATT (d=1.5) and RSAdec (d=2.3) after the training period was demonstrated. Also, significant interaction effects (time x group) were found for all parameters as the EG significantly improved performances in all tests after training. The greatest interaction effects were observed in MAS (η2=0.811) and CMJ (η2=0.759). No relevant changes in test performances were found in the CG (mean d=-0.02). These results indicate that individually speed-controlled aerobic and interval training is effective for improving specific handball performance.

2015-01-01

This study determined the physical fitness, match-activity profiles and physiological responses of representative tag football players and examined the relationship between physical fitness and the match-activity profile. Microtechnology devices and heart rate (HR) chest straps were used to determine the match-activity profiles of sixteen tag football players for five matches during the 2014 Australian National Championships. The relationships between lower body muscular power, straight line running speed and Yo-Yo intermittent recovery test level 2 (Yo-Yo IR2) and the match-activity profile were examined using Pearson’s correlation coefficients. Outside players had greater lower body muscular power (ES = 0.98) and straight line running speed (ES = 1.03–1.18) than inside players, and also covered greater very high-speed running (VHSR) distance/min (ES = 0.67) and reached higher peak running speeds (ES = 0.95) during matches. Inside and outside players performed a similar number of repeated high-intensity effort (RHIE) bouts and reported similar mean and maximum efforts per RHIE bout. However, there were differences between playing positions for mean and maximal RHIE effort durations (ES = 0.69–1.15) and mean RHIE bout recovery (ES = 0.56). Inside and outside players also reported small to moderate differences (ES = 0.43–0.80) for times spent in each HR zone. There were a number of moderate to very large correlations between physical fitness measures and match-activity profile variables. This study found lower body muscular power, straight line running speed and Yo-Yo IR2 to be related to the match-activities of representative tag football players, although differences between inside and outside players suggest that athlete testing and training practices should be modified for different playing positions.

This study examined the hypothesis that chronic (training) and acute (warm-up) loaded ventilatory activities applied to the inspiratory muscles (IM) in an integrated manner would augment the training volume of an interval running program. This in turn would result in additional improvement in the maximum performance of the Yo-Yo intermittent recovery test in comparison with interval training alone. Eighteen male nonprofessional athletes were allocated to either an inspiratory muscle loading (IML) group or control group. Both groups participated in a 6-week interval running program consisting of 3-4 workouts (1-3 sets of various repetitions of selected distance [100-2,400 m] per workout) per week. For the IML group, 4-week IM training (30 inspiratory efforts at 50% maximal static inspiratory pressure [P0] per set, 2 sets·d-1, 6 d·wk-1) was applied before the interval program. Specific IM warm-up (2 sets of 30 inspiratory efforts at 40% P0) was performed before each workout of the program. For the control group, neither IML was applied. In comparison with the control group, the interval training volume as indicated by the repeatability of running bouts at high intensity was approximately 27% greater in the IML group. Greater increase in the maximum performance of the Yo-Yo test (control: 16.9 ± 5.5%; IML: 30.7 ± 4.7% baseline value) was also observed after training. The enhanced exercise performance was partly attributable to the greater reductions in the sensation of breathlessness and whole-body metabolic stress during the Yo-Yo test. These findings show that the combination of chronic and acute IML into a high-intensity interval running program is a beneficial training strategy for enhancing the tolerance to high-intensity intermittent bouts of running.

To examine the relationship between oxygen uptake kinetics (VO2 kinetics) and physical measures associated with soccer match play, within a group of highly trained youth soccer players. Seventeen highly trained youth soccer players (age: 13.3 ± 0.4 year, self-assessed Tanner stage: 3 ± 1) volunteered for the study. Players initially completed an incremental treadmill protocol to exhaustion, to establish gaseous exchange threshold (GET) and VO2max (59.1 ± 5.4 mL kg(-1) min(-1)). On subsequent visits, players completed a step transition protocol from rest-moderate-intensity exercise, followed by an immediate transition, and from moderate- to severe-intensity exercise (moderate: 95 % GET, severe: 60 %∆), during which VO2 kinetics were determined. Physical soccer-based performance was assessed using a maximal Yo-Yo intermittent recovery test level 1 (Yo-Yo IR1) and via GPS-derived measures of physical soccer performance during soccer match play, three 2 × 20 min, 11 v 11 matches, to gain measures of physical performance during soccer match play. Partial correlations revealed significant inverse relationships between the unloaded-to-moderate transition time constant (tau) and: Yo-Yo IR1 performance (r = -0.58, P = 0.02) and GPS variables [total distance (TD): r = -0.64, P = 0.007, high-speed running (HSR): r = -0.64, P = 0.008 and high-speed running efforts (HSReff): r = -0.66, P = 0.005]. Measures of VO2 kinetics are related to physical measures associated with soccer match play and could potentially be used to distinguish between those of superior physical performance, within a group of highly trained youth soccer players.

Objectives To examine with a parallel group study design the performance and physiological responses to a 14-day off-season ‘live high-train low in the heat’ training camp in elite football players. Methods Seventeen professional Australian Rules Football players participated in outdoor football-specific skills (32±1°C, 11.5 h) and indoor strength (23±1°C, 9.3 h) sessions and slept (12 nights) and cycled indoors (4.3 h) in either normal air (NORM, n=8) or normobaric hypoxia (14±1 h/day, FiO2 15.2–14.3%, corresponding to a simulated altitude of 2500–3000 m, hypoxic (HYP), n=9). They completed the Yo-Yo Intermittent Recovery level 2 (Yo-YoIR2) in temperate conditions (23±1°C, normal air) precamp (Pre) and postcamp (Post). Plasma volume (PV) and haemoglobin mass (Hbmass) were measured at similar times and 4 weeks postcamp (4WPost). Sweat sodium concentration ((Na+)sweat) was measured Pre and Post during a heat-response test (44°C). Results Both groups showed very large improvements in Yo-YoIR2 at Post (+44%; 90% CL 38, 50), with no between-group differences in the changes (−1%; −9, 9). Postcamp, large changes in PV (+5.6%; −1.8, 5.6) and (Na+)sweat (−29%; −37, −19) were observed in both groups, while Hbmass only moderately increased in HYP (+2.6%; 0.5, 4.5). At 4WPost, there was a likely slightly greater increase in Hbmass (+4.6%; 0.0, 9.3) and PV (+6%; −5, 18, unclear) in HYP than in NORM. Conclusions The combination of heat and hypoxic exposure during sleep/training might offer a promising ‘conditioning cocktail’ in team sports. PMID:24282209

Full Text Available It has been shown that nitrate supplementation can enhance endurance exercise performance. Recent work suggests that nitrate ingestion can also increase intermittent type exercise performance in recreational athletes. We hypothesized that six days of nitrate supplementation can improve high-intensity intermittent type exercise performance in trained soccer players. Thirty-two male soccer players (age: 23 ± 1 years, height: 181 ± 1 m, weight: 77 ± 1 kg, playing experience: 15.2 ± 0.5 years, playing in the first team of a 2nd or 3rd Dutch amateur league club participated in this randomized, double-blind cross-over study. All subjects participated in two test days in which high-intensity intermittent running performance was assessed using the Yo-Yo IR1 test. Subjects ingested nitrate-rich (140 mL; ~800 mg nitrate/day; BR or a nitrate-depleted beetroot juice (PLA for six subsequent days, with at least eight days of wash-out between trials. The distance covered during the Yo-Yo IR1 was the primary outcome measure, while heart rate (HR was measured continuously throughout the test, and a single blood and saliva sample were collected just prior to the test. Six days of BR ingestion increased plasma and salivary nitrate and nitrite concentrations in comparison to PLA (p < 0.001, and enhanced Yo-Yo IR1 test performance by 3.4 ± 1.3% (from 1574 ± 47 to 1623 ± 48 m; p = 0.027. Mean HR was lower in the BR (172 ± 2 vs. PLA trial (175 ± 2; p = 0.014. Six days of BR ingestion effectively improves high-intensity intermittent type exercise performance in trained soccer players.

Asphalt is obtained at a rate of about 25 Kg per 1 Kl of oil and is produced at about 5 million tons per annum in Japan, 80 % of which is now used for the pavement of road. The purpose of this study is to examine the possibilities of developing new applications of asphalt to the anti-vibration, vibration-control and anti-noise materials, though its uses have already been diversified in fields other than for road paving, due to excellent performance regardless of cheap cost. In the paper, firstly, under a title of what is asphalt, the history, the composition and internal structure of asphalt were considered. Secondly, the dynamic characteristics of asphalt were considered. And lastly, under a title of the application of asphalt, examples of the application of asphalt to anti-noise materials were examined in the field of architecture, automobile and civil engineering respectively. Especially, in the field of civil engineering, improvements of flexibility and vibration-control by using the cement asphalt mortar (CAM) in the anti-vibration A-type slab track for railway, and also anti-noise and anti-vibration technologies applied to the road pavement body by using the ferrite asphalt were reviewed. 11 refs., 10 figs., 8 tabs.

Los resultados obtenidos, a partir de una muestra de 1.386 docentes de ESO, permiten concluir que ambos tipos de estresores diferencian válidamente en función de las variables sociodemográficas y ocupacionales. Concretamente, el estrés asociado a los problemas de comportamiento de los alumnos y a las dificultades del docente en el manejo de conflictos, incide en mayor medida en las profesoras, en los docentes de segundo ciclo y en aquellas etapas intermedias de la profesión. En definitiva, si estos hallazgos se ratifican en futuras investigaciones, se trataría de diseñar programas preventivos y/o de intervención que sean sensibles a estos factores de riesgo.

The organization of the language network undergoes continuous changes during development as children learn to understand sentences. In the present study, functional magnetic resonance imaging and behavioral measures were utilized to investigate functional activation and functional connectivity (FC) in three-year-old (3yo) and six-year-old (6yo) children during sentence comprehension. Transitive German sentences varying the word order (subject-initial and object-initial) with case marking were presented auditorily. We selected children who were capable of processing the subject-initial sentences above chance level accuracy from each age group to ensure that we were tapping real comprehension. Both age groups showed a main effect of word order in the left posterior superior temporal gyrus (pSTG), with greater activation for object-initial compared to subject-initial sentences. However, age differences were observed in the FC between left pSTG and the left inferior frontal gyrus (IFG). The 6yo group showed stronger FC between the left pSTG and Brodmann area (BA) 44 of the left IFG compared to the 3yo group. For the 3yo group, in turn, the FC between left pSTG and left BA 45 was stronger than with left BA 44. Our study demonstrates that while task-related activation was comparable, the small behavioral differences between age groups were reflected in the underlying functional organization revealing the ongoing development of the neural language network.

«Para decir la palabra yo»: Una reflexión sobre la subjetividad en la obra de José Ángel Valente

Fernández Casanova, Manuel

2008-06-01

Full Text Available The so-called Question on the subject in José Ángel Valente’s Works is going to be analysed in this essay. This essay is been thought from the writer’s reject to the definition of subjectivity as a representation of the consciousness, as a permanent request opposed to an ever-changing Reality. From this point, we’ll be able to see how at the same time his texts pose this conflict and look for the solution. This analyse will start from the following three levels: the treatment given to the lyrical self, the relationship between man and Reality, and the reformulation of the concept of authorship. This will take us from the first manoeuvres of ironical desubjectivation —in debt with an anguished perception of the existence as with to the necessity of treating the subjectivity from the compromise with the collective— to the writer’s assumption of a mystical focussing on this question, a question in which Nothingness and Otherness will play a decisive role.En el presente ensayo analizaremos el alcance de la llamada cuestión del sujeto dentro de la obra de José Ángel Valente. Partiendo de una definición de la subjetividad en clave de trasunto de la consciencia, de instancia permanente enfrentada a una realidad en constante cambio, observaremos el rechazo que el escritor experimenta ante tal concepción, así como el modo en que sus textos plantean el conflicto y buscan una resolución al mismo. Nuestro análisis atenderá fundamentalmente a tres niveles: tratamiento que recibe el yo lírico en esta obra, relación que se establece en ella entre el hombre y la realidad, y reformulación del concepto de autoría; y nos llevará desde unas primeras maniobras de desubjetivización irónica (deudoras por igual de una percepción angustiosa de la existencia y de la necesidad de abordar lo subjetivo desde el compromiso con el colectivo hasta la adopción por parte del escritor de un enfoque místico de la cuestión en el que las figuras de

Over the last few decades there has been an important consensus amongst both scholars and researchers as far as teacher occupational malaise is concerned on the leading role of both students’ disruptive behaviour and/or attitudes and teachers’ perception of the difficulty in managing conflicts. Few empirical attempts, however, have been aimed at elucidating what determinants -from either of the two fronts- have a greater prominence to this phenomenon. It is, therefore, the purpose of this study -using a sample of 1,386 teachers from Enseñanza Secundaria Obligatoria (Compulsory Secondary Education, to identify what students’ disruptive behaviour and/or attitudes as well as what sources of stress derived from conflict management best discriminate between teachers with different levels of job dissatisfaction and burnout. Results allow us to conclude that all variables validly discriminate as a function of dissatisfaction and burnout. Specifically, aspects such as dealing with the parents of disruptive students and students’ problematic behaviour (vandalism within the premises of the school, aggressions among students, verbal abuse and challenging behaviour against the teacher have an incidence on all three facets of burnout.

Key words: Job dissatisfaction, burnout, secondary education teachers.

This study examined the intermittent exercise performance and cardiovascular health profile in elite female football players in comparison to untrained young women, as well as a subgroup subjected to football training 2x1 h · week(-1) for 16 weeks. Twenty-seven Danish national team players (elite trained, ET) and 28 untrained women (UT) underwent dual-energy X-ray absorptiometry-scanning (DXA), comprehensive transthoracic echocardiography, treadmill and Yo-Yo Intermittent Endurance level 2 (IE2) testing. Eight women in UT were also tested after the football training period. Maximal oxygen uptake rate (VO2max), peak ventilation and peak lactate were 40, 18 and 51% higher (Pfootball elevated VO2max and Yo-Yo IE2 performance by 16 and 40%, respectively, and lowered fat mass by 6%. Cardiac function was markedly improved by 16 weeks of football training with 26 and 46% increases in TAPSE and E/A ratio, respectively, reaching levels comparable to ET. In summary, elite female football players have a superior cardiovascular health profile and intermittent exercise performance compared to untrained controls, but short-term football training can markedly improve the cardiovascular health status.

Full Text Available Objective: The aim of this study was to verify the effects of a specific pre-season planning on physical performance, recovery-stress state, hormonal and muscle damage markers in high-level futsal players. Method: Fifteen male futsal players, members of a high level Brazilian futsal team participated in this study. Before and after four weeks of pre-season, blood samples were collected, the Recovery Stress Questionnaire for Athletes was applied, and vertical jump tests and Yo-Yo Intermittent Recovery Level 2 tests were performed. The Internal Training Load was measured in all training sessions. Repeated measure ANOVA was used to compare the Total Weekly Training Load between different weeks. To compare the differences between pre- and post-training of all other dependent variables (except the Recovery Stress Questionnaire for Athletes scales the Student's t-test and the magnitude based inference were used. Results: The futsal pre-season improved performance in the Yo-Yo Intermittent Recovery Level 2 and Squat Jump tests. The improvement in performance tests was accompanied by an increase in testosterone, creatine kinase, testosterone/creatine kinase ratio and in the majority of the Recovery Stress Questionnaire for Athletes scales. Cortisol and the social recovery and general well-being of Recovery Stress Questionnaire for Athletes scales decreased during the futsal pre-season. Conclusions: In summary, players improved their performance in the Yo-Yo Intermittent Recovery Level 2 and Squat Jump tests in response to a futsal pre-season. Furthermore, the Internal Training Load behavior of the futsal training promoted a favorable hormonal anabolic environment and did not promote a negative disturbance in creatine kinase or stress/recovery balance, suggesting that futsal players did not report fatigue accumulation after this pre-season design.

Julian, Ross; Hecksteden, Anne; Fullagar, Hugh H. K.; Meyer, Tim

Background Female soccer has grown extensively in recent years, however differences in gender-specific physiology have rarely been considered. The female reproductive hormones which rise and fall throughout the menstrual cycle, are known to affect numerous cardiovascular, respiratory, thermoregulatory and metabolic parameters, which in turn, may have implications on exercise physiology and soccer performance. Therefore, the main aim of the present study was to investigate potential effects of menstrual cycle phase on performance in soccer specific tests. Methods Nine sub elite female soccer players, all of whom have menstrual cycles of physiological length; performed a series of physical performance tests (Yo-Yo Intermittent endurance test (Yo-Yo IET), counter movement jump (CMJ) and 3x30 m sprints). These were conducted at distinct time points during two main phases of the menstrual cycle (early follicular phase (FP) and mid luteal phase (LP)) where hormones contrasted at their greatest magnitude. Results Yo-Yo IET performance was considerably lower during the mid LP (2833±896 m) as compared to the early FP (3288±800 m). A trend towards significance was observed (p = 0.07) and the magnitude based inferences suggested probabilities of 0/61/39 for superiority/equality/inferiority of performance during the mid LP, leading to the inference of a possibly harmful effect. For CMJ (early FP, 20.0±3.9 cm; mid LP 29.6±3.0 cm, p = 0.33) and sprint (early FP, 4.7±0.1 s; mid LP, 4.7±0.1 s, p = 0.96) performances the results were unclear (8/24/68, 48/0/52, respectively). Conclusion The results of this study are in support of a reduction in maximal endurance performance during the mid LP of the menstrual cycle. However, the same effect was not observed for jumping and sprint performance. Therefore, consideration of cycle phase when monitoring a player’s endurance capacity may be worthwhile. PMID:28288203

McIntosh, ND, Love, TD, Haszard, J, Osborne, H, and Black, KE. β-hydroxy β-methylbutyrate (HMB) supplementation effects on body mass and performance in elite male rugby union players. J Strength Cond Res 32(1): 19-26, 2018-Preseason is characterized by high training volumes with short recovery periods β-hydroxy β-methylbutyrate (HMB) has been postulated to assist with recovery. β-hydroxy β-methylbutyrate has been shown to improve strength and body composition among untrained groups; the benefits of HMB among trained populations are unclear because of the methodologies employed. This randomized control trail determined the effects of 11 weeks HMB supplementation on body mass and performance measures in 27 elite rugby players. β-hydroxy β-methylbutyrate group (n = 13), mean ± SD age 20.3 ± 1.2 years, body mass 99.6 ± 9.1 kg; placebo group (n = 14), age 21.9 ± 2.8 years body mass 99.4 ± 13.9 kg for placebo. During the supplementation period, body mass increased with HMB 0.57 ± 2.60 kg but decreased with placebo 1.39 ± 2.02 kg (p = 0.029). There were no significant differences in any of the 4 strength variables (p > 0.05). However, on the yo-yo intermittent recovery test (YoYo IR-1), the placebo group improved 4.0 ± 2.8 levels but HMB decreased 2.0 ± 3.0 levels (p = 0.003). The results of this study suggest that HMB could be beneficial for gaining or maintaining body mass during periods of increased training load. However, it appears that HMB may be detrimental to intermittent running ability in this group although further research is required before firm conclusions can be made. Only 6 participants on HMB managed to complete both YoYo IR-1 tests because of injury, a larger sample size is required to fully investigate this potentially negative effect. Further, the mechanisms behind this decrement in performance cannot be fully explained and requires further biochemical and psychological investigation.

The prevalence of obesity is increasing. The aim of this study was to investigate if there is endothelial dysfunction in children with normal or excess weight, and whether the metabolic profile, adipokines, and endothelial dysfunction would be more strongly associated with physical fitness or with physical activity levels. Cross-sectional study involving children aged 5-12 years. The evaluation included venous occlusion plethysmography, serum levels of adiponectin, leptin and insulin, lipid profile, physical activity score (PAQ-C questionnaire), and physical fitness evaluation (Yo-Yo test). A total of 62 children participated in this study. Based on the body mass index, 27 were eutrophic, 10 overweight and 25 obese. Triglycerides, LDL cholesterol, HOMA-IR, and leptin were higher in the obese and excess-weight groups compared to the eutrophic group (pPAQ-C. The Yo-Yo test was significantly associated with HDL cholesterol (rho=-0.41; p=0.01), and this association remained after adjusting for body mass index z-score (rho=0.28; p=0.03). This study showed that endothelial dysfunction is already present in obese children, suggesting a predisposition to atherosclerotic disease. Moreover, HDL cholesterol levels were correlated with physical fitness, regardless of body mass index. Copyright © 2018. Published by Elsevier Editora Ltda.

This study aimed to examine and compare mood states profile and physical performance during different training phases between 2 groups of adolescent basketball players that were differentiated according to baseline testosterone concentration (T). The basketball players were submitted to an intensified training period (OVL) followed by a tapering period (TP). Twenty-three young male basketball players initiated the study. Experimental criteria data were used to stratify 16 players into high-testosterone (HTC) or low-testosterone (LTC) concentration groups. All the 16 athletes undertook 5 weeks of OVL followed by a 3-week TP. Saliva sampling, Yo-Yo intermittent recovery level 1 (Yo-Yo IRL1) test and the T-test were conducted at the beginning (T1), after OVL (T2), and after TP (T3). A similar increase in internal training load was observed during OVL when compared with TP in both groups (p 0.05); however, LTC displayed a higher score for fatigue (p 0.05). In conclusion, these results suggest that LTC athletes may be more susceptible to changes in mood states during intensified training periods. In addition, data indicate that a periodized training program successfully improved the physical performance (endurance and agility) of young basketball players; however, this improvement was not affected by testosterone level.

Rare earth oxides are usually widegap insulators like Y{sub 2}O{sub 3} with closed shell trivalent rare earth ions. In this study, solid phase rock salt structure yttrium monoxide, YO, with unusual valence of Y{sup 2+} (4d{sup 1}) was synthesized in a form of epitaxial thin film by pulsed laser deposition method. YO has been recognized as gaseous phase in previous studies. In contrast with Y{sub 2}O{sub 3}, YO was dark-brown colored and narrow gap semiconductor. The tunable electrical conductivity ranging from 10{sup −1} to 10{sup 3} Ω{sup −1 }cm{sup −1} was attributed to the presence of oxygen vacancies serving as electron donor. Weak antilocalization behavior observed in magnetoresistance indicated significant role of spin-orbit coupling as a manifestation of 4d electron carrier.

Molting is induced in decapod crustaceans via multiple leg autotomy (MLA) or eyestalk ablation (ESA). MLA removes five or more walking legs, which are regenerated and become functional appendages at ecdysis. ESA eliminates the primary source of molt-inhibiting hormone (MIH) and crustacean hyperglycemic hormone (CHH), which suppress the production of molting hormones (ecdysteroids) from the molting gland or Y-organ (YO). Both MLA and ESA are effective methods for molt induction in Gecarcinus lateralis. However, some G. lateralis individuals are refractory to MLA, as they fail to complete ecdysis by 12weeks post-MLA; these animals are in the "blocked" condition. Quantitative polymerase chain reaction was used to quantify mRNA levels of neuropeptide and mechanistic target of rapamycin (mTOR) signaling genes in YO, eyestalk ganglia (ESG), thoracic ganglion (TG), and brain of intact and blocked animals. Six of the seven neuropeptide signaling genes, three of four mTOR signaling genes, and Gl-elongation factor 2 (EF2) mRNA levels were significantly higher in the ESG of blocked animals. Gl-MIH and Gl-CHH mRNA levels were higher in the TG and brain of blocked animals and levels increased in both control and blocked animals in response to ESA. By contrast, mRNA levels of Gl-EF2 and five of the 10 MIH signaling pathway genes in the YO were two to four orders of magnitude higher in blocked animals compared to controls. These data suggest that increased MIH and CHH synthesis in the ESG contributes to the prevention of molt induction by MLA in blocked animals. The up-regulation of MIH signaling genes in the YO of blocked animals suggests that the YO is more sensitive to MIH produced in the ESG, as well as MIH produced in brain and TG of ESA animals. Both the up-regulation of MIH signaling genes in the YO and of Gl-MIH and Gl-CHH in the ESG, TG, and brain appear to contribute to some G. lateralis individuals being refractory to MLA and ESA.

Allogeneic bone marrow transplantation (BMT) with the conditioning regimen of 8 mg/kg of busulfan (BUS), 120 mg/kg of cyclophosphamide (CPM) and 10 Gy of total body irradiation (TBI) was evaluated in the patients with non-lymphocytic hematopoietic malignancies. The disease distribution of the 22 patients was as follows; 14 in the standard risk group (SRG), 8 in the high risk group (HRG). SRG included the patients with acute myeloid leukemia (AML) in the first complete remission, chronic myelogenous leukemia (CML) in chronic phase and myelodysplastic syndrome with refractory anemia, while HRG included the patients with refractory AML and CML in blastic phase. The median age of patients was 33 years old (y.o.), and the median observation period was 34.5 months No relapse occurred, but 8 patients (36%) died of various complications. Ail the patients who died of interstitial pneumonitis (4 cases) were 40 y.o. and more. Acute graft-versus-host disease (GvHD) and chronic GvHD were clinically controllable. The probability of disease-free survival rate at 5 years (5y-DFS) was 50.0% in overall patients. The 5y-DFS was 57.1% in HRG (7 cases), while 54.3% in SRG (13 cases) donated from the HLA identical siblings (20 cases). In these 13 patients in SRG, the 5y-DFS was 100% in patients under 40 y.o. (6 cases), while the probability of disease-free survival rate at 3 years was 68.6% and the 5y-DFS was 0% in patients over 40 y.o. (7 cases). Our data indicate that the conditioning regimen combining BUS, CPM and TBI for allogeneic BMT is promising for the treatment of the patients of HRG and the patients under 40 y.o. in SRG. (author)

The aging population is a growing concern as the increased fragility and frailty of the elderly results in an elevated incidence of injury as well as an increased risk of mortality and morbidity. To assess elderly injury risk, age-specific computational models can be developed to directly calculate biomechanical metrics for injury. The first objective was to develop an older occupant Global Human Body Models Consortium (GHBMC) average male model (M50) representative of a 65 year old (YO) and to perform regional validation tests to investigate predicted fractures and injury severity with age. Development of the GHBMC M50 65 YO model involved implementing geometric, cortical thickness, and material property changes with age. Regional validation tests included a chest impact, a lateral impact, a shoulder impact, a thoracoabdominal impact, an abdominal bar impact, a pelvic impact, and a lateral sled test. The second objective was to investigate age-related injury risks by performing a frontal US NCAP simulation test with the GHBMC M50 65 YO and the GHBMC M50 v4.2 models. Simulation results were compared to the GHBMC M50 v4.2 to evaluate the effect of age on occupant response and risk for head injury, neck injury, thoracic injury, and lower extremity injury. Overall, the GHBMC M50 65 YO model predicted higher probabilities of AIS 3+ injury for the head and thorax.

The basic benefit package: composition and exceptions to the rules. A case study.

With the introduction of the Health Insurance Act in 2006 in the Netherlands, the basic package of the former sickness funds became valid for all citizens. The basic benefit package has been subject to change, responding to increasing health care expenditures, medical innovations and the economic crisis. In this paper we address the decision criteria used to assess the package annually since 2006 and describe some developments that do not follow the criteria, leading to a yo-yo effect. We discuss the formation of the decision for in- or exclusion and why some treatments seem to follow an, at first sight, arbitrary in- and exclusion pathway. We first describe the official way of establishing the basic benefit package and than will describe why some treatments follow a deviated path. We conclude that political pressure and pressure from interest groups may lead to inclusion or postponement of exclusion. Reform of the organization of certain forms of health care (in our example mental care) may lead to seemingly inconsequent changes. The yo-yo effect of some treatments or pharmaceuticals may have negative effects on health care providers, insurers and patients. The seemingly well defined criteria available for defining the basic package appear to be broadly interpretable and other influences may determine the final decision of inclusion or exclusion.

Effects of Dimethyl Sulfoxide in Cholesterol-Containing Lipid Membranes: A Comparative Study of Experiments In Silico and with Cells

Science.gov (United States)

de Ménorval, Marie-Amélie; Mir, Lluis M.; Fernández, M. Laura; Reigada, Ramon

2012-01-01

Dimethyl sulfoxide (DMSO) has been known to enhance cell membrane permeability of drugs or DNA. Molecular dynamics (MD) simulations with single-component lipid bilayers predicted the existence of three regimes of action of DMSO: membrane loosening, pore formation and bilayer collapse. We show here that these modes of action are also reproduced in the presence of cholesterol in the bilayer, and we provide a description at the atomic detail of the DMSO-mediated process of pore formation in cholesterol-containing lipid membranes. We also successfully explore the applicability of DMSO to promote plasma membrane permeability to water, calcium ions (Ca2+) and Yo-Pro-1 iodide (Yo-Pro-1) in living cell membranes. The experimental results on cells in culture can be easily explained according to the three expected regimes: in the presence of low doses of DMSO, the membrane of the cells exhibits undulations but no permeability increase can be detected, while at intermediate DMSO concentrations cells are permeabilized to water and calcium but not to larger molecules as Yo-Pro-1. These two behaviors can be associated to the MD-predicted consequences of the effects of the DMSO at low and intermediate DMSO concentrations. At larger DMSO concentrations, permeabilization is larger, as even Yo-Pro-1 can enter the cells as predicted by the DMSO-induced membrane-destructuring effects described in the MD simulations.

Time perspective and positivity effects in Alzheimer's disease.

Bohn, Linzy; Kwong See, Sheree T; Fung, Helene H

2016-09-01

This study tested whether time perspective, a central tenant of socioemotional selectivity theory (Carstensen, 2006), moderates positivity effects in emotional memory. To provide measures of time perspective, young (YA; M = 22.48 years), young-old (YO; M = 67.56 years), old-old adults (OO; M = 80.24 years), and participants with moderate severity Alzheimer's disease (PAD; M = 84.28 years) completed a line task and reported subjective age. As expected, YA, YO, and OO reported successively more constrained future time perspectives. PAD showed distortion in time perspective, envisioning a future comparable with the YO, although closer matched in chronological age to OO adults. To evince positivity effects, participants were oriented to pairs of emotional images and were then tested for memory (recall and recognition) of the images. Recall and recognition memory for the images indicated an age-related advantage for positive over negative material (positivity effects). Time perspective, however, did not moderate these age effects. In memory performance, PAD were more comparable with OO adults with whom they shared a similar chronological age, rather than YO adults, who had a corresponding time perspective. These results suggest that age correlates that are shared by PAD and OO, such as reduced processing resources, rather than time perspective, may drive the age associated positivity effects.

This study examined the physical differences in adult male basketball players of different competitive level and playing position using a large cohort. In the middle of the regular season, 129 players from four different Divisions completed a Yo-YoIR1 and, after 3-to-8 days, they performed a 6-min continuous running test (Mognoni's test), a counter-movement jump (CMJ) test and a 5-min High-intensity Intermittent running test (HIT). Magnitude-based inferences revealed that differences in HIT were very likely moderate between Division I and II and likely small between Division II and III. The differences in absolute peak power and force produced during CMJs between Division I and II and between Division II and III were possibly small. Differences in Yo-YoIR1 and Mognoni's test were very likely-to-almost certain moderate/large between Division III and VI. We observed possibly-to-likely small differences in HIT and Mognoni's test between guards and forwards and almost certainly moderate differences in absolute peak power and force during CMJs between guards and centres. The ability to sustain high-intensity intermittent efforts (i.e. HIT) and strength/power characteristics can differentiate between competitive level, while strength/power characteristics discriminate guards from forwards/centres. These findings inform practitioners on the development of identification programs and training activities in basketball.

METHOD: exploratory and descriptive study undertaken in a university hospital in the South of Brazil. Fifteen women who had recently given birth, who received a consultation with the nurse in the period August - October 2011, took part in the study. Data was collected after the consultation had finished through semi-structured interviews, in which the women who had recently given birth were asked about the return to sexual activity and the feelings involved in this process. RESULTS: the principal determinant/constraint for return to sexual activity in the post-natal period was the fear of a new pregnancy. Fear of feeling pain, permission from the health professional, shame of their own bodies and changes in libido emerged as constraining and/or determinant factors in the thematic analysis. CONCLUSION: it is considered fundamental for the issue of contraception to be addressed with the woman/couple during the pre-natal consultation, so that there may be opportunities for reflection and dialog prior to the critical time itself.

Full Text Available In Mario Vargas Llosa’s opinion, two of the most lasting obsessions of García Márquez’s literary world, were the theme of plague, and the one of violence, that together form a sort of “cataclysmic vision” of history, whose literary sources were Daniel Defoe’s, A journal of the plague year, and Sophocles’, Oedipus Rex. We mention in this article the presence of those themes in García Márquez’s filmic work, beginning with the screenplays of two films: El año de la peste and Edipo Alcalde, adaptations of the cited works of Defoe and Sophocles. Afterwards we present two unpublished film treatments, Para Elisa and Dios y yo. The first is about war in Colombia, and presents an explicit reference to the “Bogotazo” (9th of April of 1948, while the second presents the theme of Latin American dictator, that García Márquez later focused in his novel El otoño del patriarca.

Nuclear attenuation of fast hadrons produced in charged-current ν and anti ν interactions in neon

1996-01-01

The production of hadrons in charged-current (anti)neutrino interactions is studied with the bubble chamber BEBC exposed to the CERN (anti)neutrino wide-band beam. Fast-hadron production in a neon target is found to be attenuated as compared to that in a hydrogen target. This feature is discussed within theoretical models based on the idea of a hadron formation length. The experimental results favour the 'constituent' over the 'yo-yo' length concept, and suggest a quark cross section in the order of 3 mb. (orig.)

Este artículo parte de los rasgos del contexto que, de modo explícito o sutil, subyacen a la explicación de la movilidad de los colombianos y sitúa en el centro del análisis una pregunta por los procesos de instalación del colectivo colombiano en España, en el que cobran especial importancia las prácticas colectivas de los inmigrantes, como una de las dimensiones del proceso de instalación en la sociedad de llegada. Para este propósito, se consideran algunas premisas teóricas que orientan el examen de las iniciativas asociativas ensayadas por los inmigrantes y se plantea una aproximación preliminar a los procesos organizativos de los colombianos en España. Si bien estos procesos no tienen todavía un peso cuantitativo significativo, constituyen un eje importante en la reflexión migratoria, toda vez que pueden hacer parte de una estrategia encaminada a garantizar niveles adecuados de sobrevivencia, de estabilización socio-económica y/o de vínculo más estrecho con su entorno cultural y social, permitiéndoles al tiempo, mejorar sus condiciones de inserción en la sociedad española. El artículo deja abierto un desafío investigativo, relacionado con la necesidad de examinar las condiciones de los procesos organizativos, su evolución y su impacto, como una arista fundamental en el espectro de las múltiples dimensiones del proceso migratorio.

A device, consisting of galvanic cells composed of solid electrolytes, was specially designed and constructed for this study. The most adequate cells for obtaining the thermodynamic data in a fast and accurate way was determined. This experimental set-up can also be used for indirect measurements in gases and liquids. Results of the measurements of the electromotive force versus temperature, performed for different samples, having an O/Fe ratio from 1.049 to 1.124 are given. From the experimental data, the following information was obtained: partial molar quantities corresponding to both Fe and O (enthalpy ΔH; entropy ΔS, and free energy ΔG). The oxide's phase boundaries between 600 and 1050 deg C were determined, showing the existence of a subphase within the range of stability of Fesub(1-y)O. The development of a theoretical model allowed to make a semiquantitative fit of the enthalpies of formation and to advance in the knowledge on the defect structure of this oxided system. According to certain theories, the wuestite, whose crystalline structure is of the NaCl type, with O in excess leads to the formation of magnetite (Fe 3 O 4 ) of spinel structure, this being the main agent causing the corrosion processes in the primary and secondary circuits of the nuclear reactors. Owing to the fact that the wuestite is similar to other transition metal oxides, such as NiO; CoO and MnO, this model may be also applied to these oxides. (M.E.L.) [es

Growth, functional capacities and motivation for achievement and competitiveness in youth basketball: an interdisciplinary approach.

2018-04-01

The interaction of multiple influences on the path to sport success is not yet fully understood by sport scientists. In this study, we examined variation in body size, functional capacities and motivation for achievement, competitiveness and deliberate practice of youth basketball players associated with differences in biological maturity status, chronological age and years of training experience. Reflecting the importance of interactive effects, we examined the relationships between the psychological variables and functional capacities. Fifty-eight male basketball players aged 9.5 to 15.5 years were considered. Variables included chronological age, estimated age at peak height velocity, stature, body mass and sitting height by anthropometry; the Work and Family Orientation and Deliberate Practice Motivation Questionnaires were also used. Finally, the Line Drill test and Yo-Yo Intermittent Recovery level 1 (Yo-Yo IR1) tests were used as functional capacities indicators for basketball. Variance components models derived from series of multilevel linear regression models revealed a substantial variation by maturity status for body size, functional capacities indicators, mastery and will to excel. The influence of estimated maturity status on mastery and will to excel was independent of age and years of experience. In contrast, no relationships were observed between psychological variables and functional capacities indicators. We conclude that growth-related changes are relevant to understanding players´ motivations for achievement, competitiveness and deliberate practice. This should be of interest to those involved in the selection and development of youth basketball players.

To gain an understanding the match demands of female football, the aims of this study were three-fold: (1) to highlight the physical qualities that discriminate selected and non-selected female Australian Football players, (2) to investigate activity profiles of female Australian Football players, and (3) to gain an understanding of the influence of physical qualities on running performance in female Australian Football match-play. Twenty-two female Australian football (AF) state academy players (mean ± SD age, 23.2 ± 4.5 years) and 27 non-selected players (mean ± SD age, 23.4 ± 4.9 years) participated in this study. The Yo-Yo Intermittent Recovery Test (Level 1), countermovement jump and 30m sprint tests were completed prior to the competitive season. During 14 matches, players wore global positioning system (GPS) units to describe the running demands of female AF match-play. Selected players were faster over 30 metres (ES=0.57; p=0.04) and covered greater distances on the Yo-Yo IR1 test (ES=1.09; pfemale AF players were faster and had greater intermittent running ability than players not selected to a State academy program. An emphasis should be placed on the development of physical fitness in this playing group to ensure optimal preparation for the national competition.

Post freezing sperm viability is one of factors which determine artificial insemination success. In the other side, bull’s or sire age influences the semen quality through sperm membrane constituent. It is known that freezing process change the sperm membrane during the processing stage. This research aims to know the effect of sire age on post freezing sperm viability of Bali cattle. The samples were collected in Singosari Artificial Insemination Centre, Malang, East Java, Indonesia on September - November 2016. Eight Bali cattle (4 and 7 y.o, 4 heads in each group) were used as semen source. Semen was collected using artificial vagina, 10 times spanning for 5 weeks (2 times per week, interval 3 and 4 days) in a row. The samples were then evaluated at fresh, chill and frozen stage. Fresh semen was diluted in Tris-citrate-egg yolk 20% (v/v) followed with chilling and freezing. Semen qualities were observed as sperm % motility (MOT), % live sperm using eosin-nigrosine staining (EOS) and % sperm membrane integrity using hypoosmotic swelling test (HOS). Variable comparisons between age groups were done using t-test. On the average, 4 y.o bulls showed higher semen quality at fresh, chill and frozen compared to 7 y.o in MOT (68.00±6.39 vs 65.9±7.62 56.40±3.71 vs 54.33±5.83 44.25±3.52 vs 40.40±7.06), EOS (72.08±6.63 vs 71.82±7.38 57.81±3.83 vs 57.41±6.32 53.16 ±8.41 vs 46.49±9.13) and HOS (60.85±13.91 vs 54.84±13.43 53.16 ±8.41 vs 46.49±9.13 44.6±9.39 vs 33.8±10.70) respectively.

Full Text Available Abstract Background The construct "meaning-in-life" (MiL has recently raised the interest of clinicians working in psycho-oncology and end-of-life care and has become a topic of scientific investigation. Difficulties regarding the measurement of MiL are related to the various theoretical and conceptual approaches and its inter-individual variability. Therefore the "Schedule for Meaning in Life Evaluation" (SMiLE, an individualized instrument for the assessment of MiL, was developed. The aim of this study was to evaluate MiL in a representative sample of the German population. Methods In the SMiLE, the respondents first indicate a minimum of three and maximum of seven areas which provide meaning to their life before rating their current level of importance and satisfaction of each area. Indices of total weighting (IoW, range 20–100, total satisfaction (IoS, range 0–100, and total weighted satisfaction (IoWS, range 0–100 are calculated. Results In July 2005, 1,004 Germans were randomly selected and interviewed (inclusion rate, 85.3%. 3,521 areas of MiL were listed and assigned to 13 a-posteriori categories. The mean IoS was 81.9 ± 15.1, the mean IoW was 84.6 ± 11.9, and the mean IoWS was 82.9 ± 14.8. In youth (16–19 y/o, "friends" were most important for MiL, in young adulthood (20–29 y/o "partnership", in middle adulthood (30–39 y/o "work", during retirement (60–69 y/o "health" and "altruism", and in advanced age (70 y/o and more "spirituality/religion" and "nature experience/animals". Conclusion This study is a first nationwide survey on individual MiL in a randomly selected, representative sample. The MiL areas of the age stages seem to correspond with Erikson's stages of psychosocial development.

Fifty-five players of the Under-14 category of Athletic Club Bilbao participated in this study. Players were classified into 4 playing positions: forwards (n=30, midfielders (n=15, defenders (n=37 and goalkeepers (n=15. Complete anthropometry, chronological age (CA, age at peak height velocity, 15-m sprint test, agility test, Yo-Yo IT level 1 (Yo-Yo IR1, counter-movement jump and hand dynamometry were measured. Results were transformed into z-scores and summed up to make two performance composites (SCORE and SCOREHG. One-way analysis of variance and a Bonferroni post-hoc test were used to examine the differences between playing positions. Multiple linear regression analysis was performed to estimate the contribution of independent variables to performance indicators. The level of significance was set at P<0.05. Significant differences were observed between playing positions in body mass and height (P<0.05; CA, maturity offset and muscle % (P<0.01; sum of skinfolds, fat %, endomorphy, sprint and agility tests (P<0.001. Stepwise regression analysis revealed that CA and sum of skinfolds were the most important predictors of performance. Collectively, playing positions were characterised by specific anthropometrical characteristics whereas no significant positional differences were observed in performance. This study provides further insight concerning coaches’ practice of selecting young soccer players because of anthropometrical characteristics rather than for performance advantages.

Algunas reflexiones acerca de cuestiones de método, inmanencia y evidencia en la filosofía moderna

Directory of Open Access Journals (Sweden)

Gustavo SARMIENTO

2014-03-01

Full Text Available En este trabajo se expone una crítica a la perspectiva de la conciencia, propia de la filosofía moderna: A partir de una errada interpretación del método de las matemáticas, Descartes y la filosofía moderna piensan que el conocimiento filosófico cierto se basa en la evidencia de un principio, la del yo existo, lo evidente dado a ese yo, más lo que se siga de ello. Como consecuencia de este error inicial, la doctrina moderna de la percepción sensible reduce toda la inmediatez del ente dado al cognoscente humano a la inmediatez de lo dado a la percepción sensible, negando que pueda haber otra inmediatez, entendida como la ausencia de representaciones, en la relación del hombre con las cosas, entre las cuales él estaría. Con esto, solo quedan el yo reducido a conciencia y sus representaciones y se niega el conocimiento inmediato de las cosas mismas, desembocando en la doctrina de la inmanencia de la conciencia.

Late complications of radiation therapy

There are cases in which, although all traces of acute radiation complications seem to have disappeared, late complications may appear months or years to become apparent. Trauma, infection or chemotherapy may sometimes recall radiation damage and irreversible change. There were two cases of breast cancer that received an estimated skin dose in the 6000 cGy range followed by extirpation of the residual tumor. The one (12 y.o.) developed atrophy of the breast and severe teleangiectasis 18 years later radiotherapy. The other one (42 y.o.) developed severe skin necrosis twenty years later radiotherapy after administration of chemotherapy and received skin graft. A case (52 y.o.) of adenoidcystic carcinoma of the trachea received radiation therapy. The field included the thoracic spinal cord which received 6800 cGy. Two years and 8 months after radiation therapy she developed complete paraplegia and died 5 years later. A truly successful therapeutic outcome requires that the patient be alive, cured and free of significant treatment-related morbidity. As such, it is important to assess quality of life in long-term survivors of cancer treatment. (author)

Full Text Available Knowledge of thermophysical properties, especially the phase transitions temperature, specific heat and enthalpy, are essential in defining the freezing process parameters as well as storage conditions of frozen food. In this work thermophysical properties of 10% model solutions prepared with 60% whey protein concentrate (WPC with various hydrocolloids addition (HVEP, YO-EH, YO-L i YO-M were investigated. Powdered whey protein concentrate was treated in equipment for tribomechanical micronization and activation at 40000 rpm (Patent: PCT/1B99/00757 just before model solutions preparation. Particle size analysis was performed using Frich –laser particle sizer “analysette 22”. The phase transition temperatures were determined by differential thermal analysis (DTA, while specific heat and enthalpy were calculated according to several mathematical equations. The results have shown that, due to tribomechanical treatment, certain changes in thermophysical and energetic properties of materials occurred. Tribomechanical treatment affects changes in granulometrical composition of WPC which result in higher abilities of reactions with hydrocolloids in model solutions and significant changes in thermophysical properties of the mentioned models.

The aim of this study was to examine the influence of hormonal status, anthropometric profile, sexual maturity level, and physical performance on the technical abilities of 40 young male soccer players during small-sided games (SSGs). Anthropometric profiling, saliva sampling, sexual maturity assessment (Tanner scale), and physical performance tests (Yo-Yo and vertical jumps) were conducted two weeks prior to the SSGs. Salivary testosterone was determined by the enzyme-linked immunosorbent assay method. Technical performance was determined by the frequency of actions during SSGs. Principal component analyses identified four technical actions of importance: total number of passes, effectiveness, goal attempts, and total tackles. A multivariate canonical correlation analysis was then employed to verify the prediction of a multiple dependent variables set (composed of four technical actions) from an independent set of variables, composed of testosterone concentration, stage of pubic hair and genitalia development, vertical jumps and Yo-Yo performance. A moderate-to-large relationship between the technical performance set and the independent set was observed. The canonical correlation was 0.75 with a canonical R 2 of 0.45. The highest structure coefficient in the technical performance set was observed for tackles (0.77), while testosterone presented the highest structure coefficient (0.75) for the variables of the independent set. The current data suggest that the selected independent set of variables might be useful in predicting SSG performance in young soccer players. Coaches should be aware that physical development plays a key role in technical performance to avoid decision-making mistakes during the selection of young players.

2007-01-01

We try to reevaluate the pathogenesis of epituberculosis in infants and children with tuberculosis, because most studies on epituberculosis were done more than 50 years ago. Nineteen children (less than 1 y/o: 12, 1 y/o: 2, 2 y/o: 3, and 4 y/o: 2) were studied by CT imaging and bronchofiberscopy in addition to gastric Mycobacterium tuberculosis examination and regular chest XP. In 13 of total 19 patients (68%), lobar or segmental epituberculosis occured after starting antituberculous chemotherapy, including a case in which epituberculosis of right upper lobe was recognized at the time of diagnosis of tuberculosis and after starting chemotherapy, epituberculosis of right middle lobe was observed. CT imaging revealed that all 19 patients had enlargement of mediastinal and/or hilar lymphonodes compressing neighboring bronchi, and 16 of total 19 patients (84%) demonstrated relevant parenchymal infiltration. Gastric Mycobacterium tuberculosis was positive in 15 out of 19 patients (79%). Bronchofiberscopy was done in 16 patients, and it demonstrated mass lesion of various size on the bronchial wall in 13 patients (81%). The present study demonstrated that epituberculosis predominantly occured in tuberculosis infants less than one year old, which was different from the previous reports. The CT imaging also makes clear that epituberculosis may be the atelectasis of lobe or segment which occurs mostly due to compression of bronchi by the enlargement of mediastinal and/or hilar lymphonodes and their early exacerbation after starting chemotherapy. Bronchofiberscopy also elucidated that bronchial wall mass lesion resulted from perforation of lynphonodes may partially contribute to the formation of epituberculosis. (author)

Metal die surfaces are improved in their resistance to abrasion and corrosion and, in particular, in their release from rubber materials and resistance to contamination. In an effort to develop techniques for optimum metal die surface modification, a PBII (plasma based ion implantation) unit is operated to implant ions into various kinds of metal die surfaces by means of nitrogen or fluorine gas plasma, and optimum conditions are studied by analyzing and evaluating the surface layers after treatment. In an effort to develop a novel ion implantation device to work on 3-dimensional shapes, conditions for stable ion implantation are determined, for which PBII gas concentration, arc plasma power, pulse frequency, application voltage, processing time, etc., are allowed to vary. In the quest for suitable conditions for metal die treatment by the PBII unit, tests are conducted involving natural rubber, butadiene rubber, nitrile rubber, chloroprene rubber, and ethylene propylene rubber and studies are conducted about their release from and contamination of metal dies and 3-dimensional metal dies into which ions have been implanted using fluorine plasma.

African American men (AA) carry unequal burdens of several conditions including cancer, diabetes, hypertension, and HIV. Engagement of diverse populations including AA men in research and health promotion practice is vital to examining the health disparities that continue to plague many racially and ethnically diverse communities. To date, there is little research on best practices that indicate locations, community areas and settings to engage AA men in research and health promotion. Traditionally, the AA church has been a key area to engage AA men and women. However, changing tides in attendance of AA parishioners require additional information to identify areas where AAs, particularly, AA men congregate. The AA barbershop has been identified as a place of social cohesion, cultural immersion and solidarity for AA men but specific sub-populations of AA men may be underrepresented. To further investigate additional locales where AA men congregate, this study engaged AA barbers and clients in several urban community barbershops in Chicago, Illinois. 127 AA men over age 18y/o receiving grooming services in 25 Chicago area barbershops across 14 predominantly AA communities were consented and recruited for a quantitative survey study. The self-administered surveys were completed in ~15 min and $10 compensation was provided to men. Descriptive statistics were reported for demographic variables and for frequency of responses for locations to find AA men of specific age ranges for health promotion and screening activities. Outside of the traditionally used churches or barbershops, the top recommended recruitment sites by age were: 18-29y/o- city park or a recreational center; 30-39y/o- gym, bars or the street; 40-49y/o- various stores, especially home improvement stores, and the mall; and 50y/o+- fast food restaurants in the mornings, such as McDonalds, and individual's homes. The study participants also reported that locations where AA men congregate vary by age

We investigated the relationship between the Handball Complex-Test (HBCT) and two selected field performance tests (the repeated sprint ability [RSA], and the Yo-Yo Intermittent Recovery Test) in elite handball players. Nineteen handball players (age: 25.7±5.1 years) were drawn from the First Professional German League. The HBCT consists of four activity series (AS): agility parcours, defensive action, sprint (10 m, 20 m) and throw-on-goal parcours; these activities were completed twice, with five active pauses of 30-35 s, and a follow-up of recovery over the subsequent 10 minutes. The RSA comprised 6 x (15+15 m) sprints starting every 20 s; scoring noted best time (RSAbest), total time (RSATT) and decrement (RSAdec). In the Yo-Yo Intermittent Recover, we recorded the total distance covered (TD). Heart rates (HR) were recorded throughout and recovery was assessed for measurements immediately post-test (R0) and 10 minutes after completing the test (R10). A strong correlation was found between HBCT and fastest 10 m and 20 m RSA sprint times (r=0.811, r=0.815, respectively). Also, the HBCT total 10 m and 20 m sprint times showed a strong positive association with RSATT (r=0.70; r=0.63, respectively), and the RSA heart rate post-test was strongly correlated with the HBCT heart rate after round two (r=0.865). Data from the match-specific HBCT Test shows a strong positive association with other more generic intermittent field test measurements. These observations support the validity of using the generic tests to monitor current fitness and responses to training in team handball players.

To compare the age at menarche obtained by recall method according to the time elapsed since the event, in order to verify the importance of the recall bias. Were evaluated 1,671 girls (7-18 years) at schools in Campinas-SP regarding the occurrence of menarche by the status quo method (menarche: yes or no) and the recall method (date of menarche, for those who mentioned it). The age at menarche obtained by the status quo method was calculated by logit, which considers the whole group, and the age obtained by the recall method was calculated as the average of the mentioned age at menarche. In this group, the age at menarche was obtained by the difference between the date of the event and the date of birth. Girls who reported menarche (883, 52.8%) were divided into four groups according to the time elapsed since the event. To analyze the results, we used ANOVA and logistic regression for the analysis, with a significance level of 0.05. The age at menarche calculated by logit was 12.14 y/o (95% CI 12.08 to 12.20). Mean ages obtained by recall were: for those who experienced menarche within the previous year 12.26 y/o (±1.14), between > 1-2 years before, 12.29 y (±1.22); between > 2-3 years before, 12.23 y/o (±1.27); and more than 3 years before, 11.55y/o (±1.24), p recall method was similar for girls who menstruated within the previous 3 years (and approaches the age calculated by logit); when more than 3 years have passed, the recall bias was significant.

19 Streptococcus thermophilus with high exopolysaccharide production were isolated from traditional Chinese fermented dairy products. The exopolysaccharide and viscosity of milk fermented by these 19 isolates were assayed. The strains of Streptococcus thermophilus zlw TM11 were selected because its fermented milk had the highest exopolysaccharide content (380 mg/L) and viscosity (7716 mpa/s). Then Streptococcus thermophilus zlw TM11 was combined with Lactobacillus delbrueckii subsp. bulgaricus 3 4.5 and the combination was named SH-1. The quality of the yogurt fermented by SH-1 and two commercial starter cultures (YO-MIX 465, YF-L711) were compared. It was shown that the exopolysaccharide content of yogurt fermented by SH-1 was similar to that of yogurt fermented by YF-L711 and significantly higher than YO-MIX 465 (p yogurt fermented by SH-1 had the lowest syneresis (8.5%) and better texture and sensory than the samples fermented by YO-MIX 465 and YF-L711. It manifested that the selected higher exopolysaccharide production starter SH-1 could be used as yogurt starter and reduce the amount of adding stabilizer, which can compare with the imported commercial starter culture.

LaGaO 3 perovskites doped with Sr or Ba at the La site and Mg at the Ga site were prepared by solid-state reaction or sol-gel method and characterized. Enthalpies of formation from constituent oxides at 298 K were determined by high-temperature oxide melt solution calorimetry. Energetic trends are discussed in terms of defect chemistry. As oxygen deficiency increases, formation enthalpies define three trends, LaGa 1- yMg yO 3- δ (LGM), La 1- xSr xGa 1- yMg yO 3- δ (LSGM), and La 1- xBa xGa 1- yMg yO 3- δ (LBGM). They become less exothermic with increasing doping, suggesting a dominant destabilization effect from oxygen vacancies. The endothermic enthalpy of vacancy formation is 275±37, 166±18 and 138±12 kJ/mol of VO·· for LGM, LBGM and LSGM, respectively. Tolerance factor and ion size mismatch also affect enthalpies. In terms of energetics, Sr is the best dopant for the La site and Mg for the Ga site, supporting earlier studies, including oxygen ion conductivity and computer modeling.

Atmospheric pollution in urban areas is a major worldwide concern with potential adverse impacts on wildlife and humans. Biomonitoring can provide direct evidence of the bioavailability and bioaccumulation of toxic metals in the environment that is not available with mechanical air monitoring. The current study continues our evaluation of the usefulness of homing pigeon lung tissue as a biomonitor of atmospheric pollution. Homing pigeons (1-2, 5-6, and 9-10+ year old (yo)) collected from Guangzhou during 2015 were necropsied and concentrations of cadmium (Cd), lead (Pb), and mercury (Hg) were measured in lung tissue. Lung Cd and Pb concentrations were significantly greater in 9-10+-year-old pigeons compared with those in other age groups, indicating their bioavailability and bioaccumulation. Lung Pb and Cd concentrations measured in 5-yo pigeons collected from Guangzhou during 2015 were significantly lower than concentrations reported in 5-yo homing pigeons collected from Guangzhou during 2011 and correlated with concentrations measured using mechanical air monitoring. In addition to temporal differences, spatial differences in concentrations of Cd, Pb, and Hg reported in ambient air samples and in pigeon lung tissues collected from Beijing and Guangzhou are discussed.

De este modo, el análisis busca considerar la noción de que la formación de los más diferentes grupos está cruzada por un ideal regulador del yo, en sus formas de experiencia de vida. Cuestiona también la búsqueda por la verdad del sujeto en visiones totales, comprendiendo que somos y vivimos dentro de narrativas construidas a muchas manos, y, que tal supuesto, abre muchas posibilidades teóricas en el abordaje de antiguos y nuevos temas que interesan a los profesionales de la salud, para los cuales se consolidan nuevas relaciones entre las ciencias de la salud, las ciencias humanas y las ciencias sociales.

Full Text Available Head injury is the leading cause of fatality and long-term disability for children. Pediatric heads change rapidly in both size and shape during growth, especially for children under 3 years old (YO. To accurately assess the head injury risks for children, it is necessary to understand the geometry of the pediatric head and how morphologic features influence injury causation within the 0-3 YO population. In this study, head CT scans from fifty-six 0-3 YO children were used to develop a statistical model of pediatric skull geometry. Geometric features important for injury prediction, including skull size and shape, skull thickness and suture width, along with their variations among the sample population, were quantified through a series of image and statistical analyses. The size and shape of the pediatric skull change significantly with age and head circumference. The skull thickness and suture width vary with age, head circumference and location, which will have important effects on skull stiffness and injury prediction. The statistical geometry model developed in this study can provide a geometrical basis for future development of child anthropomorphic test devices and pediatric head finite element models.

Claims are made for the validity of some self-report pain scales for 3- and 4-year-old children, but little is known about their ability to use such tools. This systematic review identified self-report pain intensity measures used with 3- and/or 4- year-old participants (3-4yo) and considered their reliability and validity within this age span. The search protocol identified research articles that included 3-4yo, reported use of any pain scale, and included self-reported pain intensity ratings. A total of 1,590 articles were screened and 617 articles met inclusion criteria. Of the included studies, 98% aggregated self-report data for 3-4yo with data for older children, leading to overestimates of the reliability and validity of self-report in the younger age group. In the 14 studies that provided nonaggregated data for 3-4yo, there was no evidence for 3-year-old and weak evidence for 4-year-old children being able to use published self-report pain intensity tools in a valid or reliable way. Preschool-age children have been reported to do better with fewer than the 6 response options offered on published faces scales. Simplified tools are being developed for young children; however, more research is needed before these are adopted. Some self-report pain scales have been promoted for use with 3- and 4-year-old children, but this is on the basis of studies that aggregated data for younger and older children, resulting in overestimates of reliability and validity for the preschool-age children. Scales with fewer response options show promise, at least for 4-year-old children. Copyright © 2017 American Pain Society. Published by Elsevier Inc. All rights reserved.

Full Text Available The Tremp Formation is the continental lateral equivalent of the Arén Sandstone Formation. Both formations are part of regressive depositional sequences, formed during a relative sea level rise. At the top of the Isona anticline and in tbe south flank of the Sant Comeli anticline, four lithostratigraphic units are distinguisbed in the Tremp Formation. The sedimentary evolution of each of these units is related to tectonic reactivation and a slow down of the diastrophism. The successive sedimentary environments inferred for these units are the following: lagoon and/or fluvial plain, fluvial plain, tidal flat and/or lacustrine-palustrine. At the base and/or within sorne of these units there are progressive unconformities. The maximum slow down of the diastrophism would correspond to sedimentation in the tidal flat and/or lacustrine environments.La Fm. Tremp es el equivalente lateral continental de la Fm.

Junior basketball athletes require a well-designed resistance training program to improve their physical development. Lack of expert supervision and resistance training in junior development pathways may be overcome by implementing an online video-based program. The aim of this study was to compare the magnitude of improvement (change) in physical performance and strength and functional movement patterns of junior basketball athletes using either a fully supervised or an online video-based resistance training program. Thirty-eight junior basketball athletes (males, n = 17; age, 14 ± 1 year; height, 1.79 ± 0.10 m; mass, 67 ± 12 kg; females, n = 21; age, 15 ± 1 year; height, 1.70 ± 0.07 m; mass, 62 ± 8 kg) were randomly assigned into a supervised resistance training group (SG, n = 13), video training group (VG, n = 13) or control group (CG, n = 12) and participated in a 6-week controlled experimental trial. Pre- and posttesting included measures of physical performance (20-m sprint, step-in vertical jump, agility, sit and reach, line drill, and Yo-Yo intermittent recovery level 1), strength (15 s push-up and pull-up), and functional movement screening (FMS). Both SG and VG achieved 3-5% ± 2-4% (mean ± 90% confidence limits) greater improvements in several physical performance measures (vertical jump height, 20-m sprint time, and Yo-Yo endurance performance) and a 28 ± 21% greater improvement in push-up strength compared with the CG. The SG attained substantially larger gains in FMS scores over both the VG (12 ± 10%) and CG (13 ± 8%). Video-based training appears to be a viable option to improve physical performance and strength in junior basketball athletes. Qualified supervision is recommended to improve functional movement patterns in junior athletes.

Japanese older people experienced drastic changes in family structure and values after World War II at different life stages by birth cohorts. We examined how linkages between different types of social ties and life satisfaction (LS) vary across cohorts, in conjunction with age and survey year differences. Data from face-to-face interviews conducted in 1987, 1999, and 2012 with a nationally representative sample of older Japanese (N = 4,917) were analyzed. The participants were members of 4 birth cohorts (C1: 1901-1912, C2: 1913-1924, C3: 1925-1936, C4: 1937-1949), categorized into 6 groups based on cohort and age at time of measurement (young-old [YO]: 63-74; old-old [OO]: 75-86): C1OO, C2YO, C2OO, C3YO, C3OO, and C4YO. Effects of social networks on LS among the 6 groups were compared simultaneously and separately by gender using the Amos software. There were significant cohort variations in the linkages between family network and LS. The positive association between being married and LS was stronger for later cohorts (C3, C4) among men, whereas that of co-residence with a child and LS was stronger for the earlier cohorts (C1, C2) among women. Moreover, the positive association between meeting with nonfamily members and LS increased from 1987 to 2012 among women, indicating a period effect over a cohort effect. The effects of being married and participation in community groups on LS also changed with age. Our results suggest that linkages between social relations and LS should be interpreted within the context of individual and social changes over time. (c) 2015 APA, all rights reserved).

The residual hydrothermalism associated with submarine volcanoes, following an eruption event, plays an important role in the supply of CO2 to the ocean. The emitted CO2 increases the acidity of seawater. The submarine volcano of El Hierro, in its degasification stage, provided an excellent opportunity to study the effect of volcanic CO2 on the seawater carbonate system, the global carbon flux, and local ocean acidification. A detailed survey of the volcanic edifice was carried out using seven CTD-pH-ORP tow-yo studies, localizing the redox and acidic changes, which were used to obtain surface maps of anomalies. In order to investigate the temporal variability of the system, two CTD-pH-ORP yo-yo studies were conducted that included discrete sampling for carbonate system parameters. Meridional tow-yos were used to calculate the amount of volcanic CO2 added to the water column for each surveyed section. The inputs of CO2 along multiple sections combined with measurements of oceanic currents produced an estimated volcanic CO2 flux = 6.0 105 ± 1.1 105 kg d-1 which is ~0.1% of global volcanic CO2 flux. Finally, the CO2 emitted by El Hierro increases the acidity above the volcano by ~20%.

From 1991 to 1994, 39 ankles of 38 patients underwent surgical open reduction and internal fixation for pilon fractures. These patients included 29 males and 9 females with an average age of 38.6 y/o (range 28 y/o-58 y/o). The follow up and evaluation period averaged 31.7 months (range 22Ms-44Ms), during which time a standing x-ray for arthrosis grading and functional scale was used for clinical evaluation. Complications included 1 case of infection, 1 case of loss reduction, 2 cases of partial skin necrosis and 2 cases of delayed union. Post-traumatic arthritis occurred in 23 ankles (59%) but only 4 ankles of grade 4 arthrosis resulted in poor functional scale and the overall satisfactory rate was 82%. It was found that anatomic reduction, rigid fixation and early motion exercise are important to successful treatment of ankle fractures. Regarding pilon fracture, specifically the severity of fracture pattern and delay of reduction are important problems to overcome to ensure successful results. Therefore, adequate surgical approach for entire view of ankle joint, reduction and fixation of fibula, sufficient bone graft for articular support, intraoperative x-ray check and postoperative immobilization are essential for the achievement of better clinical results.

Full Text Available 19 Streptococcus thermophilus with high exopolysaccharide production were isolated from traditional Chinese fermented dairy products. The exopolysaccharide and viscosity of milk fermented by these 19 isolates were assayed. The strains of Streptococcus thermophilus zlw TM11 were selected because its fermented milk had the highest exopolysaccharide content (380 mg/L and viscosity (7716 mpa/s. Then Streptococcus thermophilus zlw TM11 was combined with Lactobacillus delbrueckii subsp. bulgaricus 3 4.5 and the combination was named SH-1. The quality of the yogurt fermented by SH-1 and two commercial starter cultures (YO-MIX 465, YF-L711 were compared. It was shown that the exopolysaccharide content of yogurt fermented by SH-1 was similar to that of yogurt fermented by YF-L711 and significantly higher than YO-MIX 465 (p<0.05. In addition, the yogurt fermented by SH-1 had the lowest syneresis (8.5% and better texture and sensory than the samples fermented by YO-MIX 465 and YF-L711. It manifested that the selected higher exopolysaccharide production starter SH-1 could be used as yogurt starter and reduce the amount of adding stabilizer, which can compare with the imported commercial starter culture.

Hypothyroidism in patients with renal failure (RF) causes many metabolic and clinical problems, and both these diseases can mutually exacerbate their disturbances. The aim of this study was to evaluate the effect of hypothyroidism, and end-stage renal disease (ESRD) on conversion of thyroid hormones (TH) in patients with ESRD treated with chronic hemodialysis (HD). The study was performed in 74 patients, including 41 women (K) and 33 men (M) aged 28-83 y.o. in 4 groups: G1 - 12 people with ESRD treated with HD and with newly diagnosed hypothyroidism without substitution (6 K and M 6) aged 66,83±12,90 y.o., G2 - 26 patients with ESRD treated with HD without hypothyroidism (10 F, 16 M) aged 58,85±15,52 y.o., G3 - 11 hypothyroid patients without RF (9 K, 2 M) aged 54,73±21,26 y.o., G4 - 25-persons from control group of healthy subjects (16 M, 9 M) aged 51,24±12,58 y.o. In all subjects the concentration of TSH and TH (T4, T3, fT4, TSH, FT3, rT3) were measured and values of conversion factors (T3/T4, FT3/ fT4, rT3/fT4 and rT3/fT3) and binding TH to protein factors (fT4/T4 and fT3/T3) were calculated. Lower concentration of T3 (p=0.012), fT3 (phypothyroidism than in healthy subjects. Renal failure with concomitant hypothyroidism intensify the disturbances of T4 to T3 conversion (p=0.034) and hypothyroidism with concomitant renal failure disrupts binding of T3 to proteins (p=0.001). FT3 to fT4 ratio in renal failure with concomitant hypothyroidism group was significantly lower than in each other group. rT3 concentrations were the highest in healthy subjects. Concomitance of hypothyroidism and end-stage renal disease reduces the conversion of thyroxine to triiodothyronine, but does not increase the production of rT3. Hypothyroidism significantly increases the disorders of thyroid hormones in end-stage renal disease. There is decreased tendency to bind of thyroid hormone to protein in hypothyroidism in patients with end-stage renal disease.

Fluoroelastmers are well known for their resistance to heat and fluids and have become major material for crankcase oil sealers. On the other hand new additive formulations are developed for engine lubricants used for fuel economic gasoline engines. In this paper the effects of those additives on properties of fluoroelastmers are investigated. The results of the immersion tests of both test plaques and oil sealer products indicates that dithiocarbamates friction modifier have hardening effects on fluoroelastomers. The fluoroelastmer deterioration mechanism is presumed by analysis of elastmer samples after immersion in oil. 6 refs., 9 figs., 3 tabs.

Atomic approaches in metastable antiprotonic helium atoms. REPLY to 'analysis of the lifetimes and fractions of antiprotons trapped in metastable antiprotonic-helium states' by I. Shimamura and M. Kimura

In the present note the authors clarify the purpose of YO and complement its essential points, thus showing that the criticisms of SK are inappropriate. The paper YO [1] was aimed at discussing some new aspects related to the metastability of hadronic helium atoms which had been discovered when negative kaons [2], negative pions [3] and antiprotons [4] were stopped in liquid helium. The delayed fraction, time spectrum shape and lifetimes were the observables. Further experimental studies are in progress [5], and as of today there is no successful explanation for these interesting phenomena. So, YO tried to give brief and rather qualitative estimates for the observations in an intuitive way, considering only the leading terms. The following problems are discussed in as simple a manner as possible, starting from the exotic-atom viewpoints of Condo [6] and Russell [7]: i)the atomic core polarization effect, ii)the structure and radiative lifetimes, iii)the non-statistical distribution of the angular momentum and an estimate of the delayed fraction, and iv)the isotope effect, though the title represents only i). To respond to the comments of SK, it is important to consider the correspondence between the atomic approach and the molecular approach for the metastable antiprotonic helium atom of Condo-Russell. We therefore begin this note with a discussion of this aspect. (author)

to describe the epidemiologic, clinical, and prognostic aspects of the emergency and non-emergency transfers of obstetric patients to Yalgado Ouédraogo University Hospital Center (UHC-YO) in Ouagadougou. this retrospective descriptive study looked at the outcomes of women transferred, on an emergency basis or not, to the obstetrics department of the UHC-YO. The study population comprised all women transferred to the department during 2010, 2011, and 2012. during the study period, there were 9,806 admissions for obstetric disorders: 43% were transfers. The patients' mean age was 26.11 years [(13-49]. Women transferred from health care facilities within the city of Ouagadougou accounted for 96% of the sample. The leading reason for these transfers - emergency or not - was preeclampsia and eclampsia (24.57%). We recorded a total of 161 maternal deaths, for a mortality rate of 3.9%. Approximately 26.55% of the newborns received immediate intensive care and were then transferred to the neonatology department. maternal and neonatal prognosis is always poor in cases transferred to UHC-YO, despite increased funding for emergency obstetric and neonatal care. Increased population awareness of the importance of prenatal consultation and adequate funding for health care facilities to provide equipment for emergency transfers and staff training in the management of obstetric and neonatal emergencies would probably improve these mortality and morbidity rates.

The validity of RSM was tested against a 10 × (15 + 15 m repeated sprint ability test (RSA, Yo-Yo Intermittent Recovery test Level 1 (Yo-Yo IR1, squat jump (SJ and countermovement jump (CMJ. To test the reliability of RSM, the participants repeated the testing sessions of RSM and RSA 1 week later. Both RSA and RSM tests showed good to excellent reliability of the total time (TT, best time (BT, and weakest time (WT. The results of the correlation analysis showed significant inverse correlations between maximum aerobic capacity and TT in RSA (r = −0.57, p ≤ 0.05 and RSM (r = −0.76, p ≤ 0.01. There was also a significant inverse correlation between maximum aerobic capacity with fatigue index (FI in RSA test (r = −0.64, p ≤ 0.01 and in RSM test (r = −0.53, p ≤ 0.05. BT, WT, and TT of RSA was largely-to-very largely correlated with BT (r = 0.58, p ≤ 0.01, WT (r = 0.62, p ≤ 0.01, and TT (r = 0.65, p ≤ 0.01 of RSM. BT in RSM was also correlated with FI in RSM (r = 0.88, p ≤ 0.01. In conclusion, based on the findings of the current study, the recently developed RSM test is a valid and reliable test and should be utilized for assessment of repeated sprint ability in handball players.

To test the reliability of RSM, the participants repeated the testing sessions of RSM and RSA 1 week later. Both RSA and RSM tests showed good to excellent reliability of the total time (TT), best time (BT), and weakest time (WT). The results of the correlation analysis showed significant inverse correlations between maximum aerobic capacity and TT in RSA (r = −0.57, p ≤ 0.05) and RSM (r = −0.76, p ≤ 0.01). There was also a significant inverse correlation between maximum aerobic capacity with fatigue index (FI) in RSA test (r = −0.64, p ≤ 0.01) and in RSM test (r = −0.53, p ≤ 0.05). BT, WT, and TT of RSA was largely-to-very largely correlated with BT (r = 0.58, p ≤ 0.01), WT (r = 0.62, p ≤ 0.01), and TT (r = 0.65, p ≤ 0.01) of RSM. BT in RSM was also correlated with FI in RSM (r = 0.88, p ≤ 0.01). In conclusion, based on the findings of the current study, the recently developed RSM test is a valid and reliable test and should be utilized for assessment of repeated sprint ability in handball players.

Tasmania's aquaculture industry produces over 40,000 tonnes of fish annually, valued at over AUD500M. Aquaculture divers perform repetitive, short-duration bounce dives in fish pens to depths up to 21 metres' sea water (msw). Past high levels of decompression illness (DCI) may have resulted from these 'yo-yo' dives. This study aimed to assess working divers, using Doppler ultrasonic bubble detection, to determine if yo-yo diving was a risk factor for DCI, determine dive profiles with acceptable risk and investigate productivity improvement. Field data were collected from working divers during bounce diving at marine farms near Hobart, Australia. Ascent rates were less than 18 m·min⁻¹, with routine safety stops (3 min at 3 msw) during the final ascent. The Kisman-Masurel method was used to grade bubbling post dive as a means of assessing decompression stress. In accordance with Defence Research and Development Canada Toronto practice, dives were rejected as excessive risk if more than 50% of scores were over Grade 2. From 2002 to 2008, Doppler data were collected from 150 bounce-dive series (55 divers, 1,110 bounces). Three series of bounce profiles, characterized by in-water times, were validated: 13-15 msw, 10 bounces inside 75 min; 16-18 msw, six bounces inside 50 min; and 19-21 msw, four bounces inside 35 min. All had median bubble grades of 0. Further evaluation validated two successive series of bounces. Bubble grades were consistent with low-stress dive profiles. Bubble grades did not correlate with the number of bounces, but did correlate with ascent rate and in-water time. These data suggest bounce diving was not a major factor causing DCI in Tasmanian aquaculture divers. Analysis of field data has improved industry productivity by increasing the permissible number of bounces, compared to earlier empirically-derived tables, without compromising safety. The recommended Tasmanian Bounce Diving Tables provide guidance for bounce diving to a depth of 21 msw

ZnO wafers implanted with 60 keV Sn + ions at room temperature (RT) and at 110 K are investigated by means of X-ray diffraction (XRD) and photoluminescence (PL) techniques. The effect of implantation temperature is evident in the XRD and PL data. A yellow-orange (YO) band near 600 nm appears in the PL spectra of the ZnO wafers implanted to the doses of 4x10 14 and 8x10 14 ions/cm 2 at RT. The intensity of this band increases and the peak position blue-shifts after illumination of the samples with the 325 nm line of a He-Cd laser. The PL data suggests that the CB (conduction band)→V O + and Zn i + →V Zn - transitions contribute to the photoemission of the YO band.

The materials except cement, water and aggregate added into the cement paste, mortar or concrete before the execution of smashing are called mixed materials. The mixed materials are indispensable to the concrete for improving the quality of the fresh concrete as well as the hardened concrete; providing the characteristics suitable for the operation; and increasing the economy. In this paper, the main mixed materials including fly ash, which is the by-product in coal thermoelectric power station; silica fume; micropowder of slag in blast furnace; expansive materials and so on are described summarily. Especially, silica fume is the by-product, which are the super micro-powders with the average size around 0.1 micrometer, collected by the dust-collector from the waste gas generated during the manufacture in the electric furnace of ferrosilicon, which is an alloy iron, or silicon metal used as the deacidificating and desulfurizing agents in the steel production. But the most part thereof is depended on the import since the domestic output is low. 38 refs., 19 figs., 6 tabs.

Resting state brain activity incorporates different components, including the Default Mode Network and the Dorsal Attention Network, also known as task-negative network and task-positive network respectively. These two networks typically show an anticorrelated activity during both spontaneous oscillations and task execution. However modifications of this anticorrelated activity pattern with age and pathology are still unclear. The present study aimed to investigate differences in resting state Default Mode Network-Dorsal Attention Network functional anticorrelation among young adults, healthy elders and Mild Cognitive Impairment patients. We retrospectively enrolled in this study 27 healthy young adults (age range: 25-35 y.o.; mean age: 28,5), 26 healthy elders (age range: 61-72 y.o.; mean age: 65,1) and 17 MCI patients (age range 64-87 y.o.; mean age: 73,6). Mild Cognitive Impairment patients were selected following Petersen criteria. All participants underwent neuropsychological evaluation and resting state functional Magnetic Resonance Imaging. Spontaneous anticorrelated activity between Default Mode Network and Dorsal Attention Network was observed in each group. This anticorrelation was significantly decreased with age in most Default Mode Network-Dorsal Attention Network connections (p Default Mode Network and the right inferior parietal sulcus node of the Dorsal Attention Network was significantly decreased when comparing Mild Cognitive Impairment with normal elders (p Default Mode Network and Dorsal Attention Network is part of the normal aging process and that Mild Cognitive Impairment status is associated with more evident inter-networks functional connectivity changes.

Full Text Available The case fatality ratio (CFR of Ebola virus disease (EVD can vary over time and space for reasons that are not fully understood. This makes it difficult to define the baseline CFRs needed to evaluate treatments in the absence of randomized controls. Here, we investigate whether viremia in EVD patients may be used to evaluate baseline EVD CFRs.We analyzed the laboratory and epidemiological records of patients with EVD confirmed by reverse transcription PCR hospitalized in the Conakry area, Guinea, between 1 March 2014 and 28 February 2015. We used viremia and other variables to model the CFR. Data for 699 EVD patients were analyzed.

An order of magnitude increase in mean viremia in cases after July 2014 compared to those before coincided with a 14% increase in the CFR. Our findings come from a large hospital-based study in Conakry and may not be generalizable to settings with different case profiles, such as with individuals who never sought care.Viremia in EVD patients was a strong predictor of death that partly explained variations in CFR in the study population. This study provides baseline CFRs by viremia group, which allow appropriate adjustment when estimating efficacy in treatment studies. In randomized controlled trials, stratifying analysis on viremia groups could reduce sample size requirements by 25%. We hypothesize that monitoring the viremia of hospitalized patients may inform the

Full Text Available A disparity population data set in the current literature with limited reports among Asian samples and the inconsistent findings among different ethnic groups warrant further investigation on the association between alpha-actinin-3 (ACTN3 R/X gene polymorphism and human physical performance in Asian population. This study was designed to examine the association between ACTN3 R/X gene polymorphism and physical performance of multi-ethnic Malaysian population. One hundred eighty well-trained athletes (34 endurance, 41 strength, and 105 intermittent and 180 controls were drawn from four ethnic groups in Malaysia (Malay, Chinese, Indian, and Other Bumiputra. A sample of deoxyribonucleic acid (DNA was retrieved from a buccal swab from each participant and the ACTN3 R/X genotype was identified through polymerase chain reaction and restriction fragment length polymorphism analysis. The strength and endurance performances of the athletes were evaluated with maximal voluntary contraction and Yo-Yo intermittent recovery level 2 tests, respectively. The independent t-test, chi-square, multivariate, and one-way analysis of variance were used for data analysis. ACTN3 R/X alleles (p = 0.672 and genotype (p = 0.355 frequencies did not vary much between the multi-ethnic groups of Malaysian athletes. These small variations did not have any influence on handgrip strength (p = 0.334, leg strength (p = 0.256, and Yo-Yo intermittent recovery level 2 performance (p = 0.425 between these ethnic groups. The RR and XX genotypes were more frequent among strength and intermittent athletes, respectively. Athletes with the RR genotype had greater handgrip than those with the RX genotype (p = 0.031, but not different from athletes with the XX genotype (p = 0.228. Athletes with RR genotype also have a higher leg strength than those with the RX (p = 0.001 and XX genotype (p = 0.010. However, the endurance performance was similar among genotype groups (p = 0.385. The ACTN3 R

En cierto modo, aunque por un camino diferente -ella desde la historia, yo desde la literatura- ambos habíamos llegado a sospechar casi al unísono que el tema no era tan escaso como afirman algunos historiadores y que, más bien, nos hallábamos frente a una zona poco documentada de nuestra cultura. En efecto, sólo Vicente Pérez Silva, un investigador vinculado al Instituto Caro y Cuervo, se había preocupado antes por el tema, elaborando una bibliografía que, si bien puede considerarse un trabajo pionero en Colombia, también es un esfuerzo de recopilación con abundantes y notorias imperfecciones.

Segmentation analysis of financial savings markets through the lens of psycho-demographics

Directory of Open Access Journals (Sweden)

Tendy Matenge

2016-08-01

Full Text Available Purpose: This study seeks to contribute to the discourse of financial savings market segmentation. The study explores different segments of savers on the basis of demographic and psychographic characteristics that are unique to each segment relying on the perspectives of a sample of consumers of financial saving programmes. Design/methodology/approach: Principles of perceptual mapping were used to analyse 33 semi-structured interviews that gathered data on the participants’ psychographic make-up such as personal values, motives for saving, attitudes towards savings and perceived conditions of savings. Findings: Eight distinct segments emerged on each psychographic characteristic based on the participants’ demographics of income, gender and age. However, only five were sizeable enough to be interpreted, being three segments from the males’ category and two from the females’ category. The three segments that emerged within the male category are young low-income earners (YoLI, young high-income earners (YoHI and old high-income earners (OHI while the two female segments include YoLI and OHI. The most sizeable segment of savers in both gender-based categories is one of old adults who have a high income. These segments vary in terms of values, motives and perceptions. Originality/value: The study suggests that a multi-dimensional approach of segmenting financial savings markets is more effective, as neither the demographic nor the psychographic segmentation can fully describe the saving behaviour of consumers. Research implications: The findings of the present study provide strategic communication implications for financial institutions for the respective segments.

The epidemiology of Influenza C virus (FLUCV) infections remains poorly characterised. Here, we have examined the age- and location-specific seroprevalence of antibodies against FLUCV in 1441 sera from metropolitan continental France (Marseille), South-West Indian Ocean French territories (Reunion Island) and United-Kingdom (Edinburgh) using a combination of haemagglutination inhibition, virus neutralisation and ELISA assays. Our results show that immunity to FLUCV is common in all locations studied (global seroprevalence values >50%) and that the first immunising contacts generally occur early in life (i.e., in the 0-4 year-old age group). The latter item is further supported by the detection of FLUCV RNA by RT-PCR in naso-pharyngeal samples collected in patient attending the Emergency Room of the Public hospitals of Marseille, France with a large majority of children under 10 years-old: 17 (60.7%) in children ≤3 yo, 10 (35.7%) in the 4-10 yo age group and 1 (3.6%) in an adult (49yo). The temporal distribution of cases was atypical with regard to influenza (a large proportion of cases occurred in spring and summer) and the clinical presentation was diverse, including but being not limited to classical Influenza-like-Ilnesses. Altogether, our results indicate an intense circulation of FLUCV in the different study areas and an early occurrence of infection in human life. Flu C appears to be a widely under-diagnosed and under-studied human paediatric disease that obviously deserves further clinical and epidemiological characterisation.

Adrenal venous sampling (AVS) is the definitive evaluation for primary aldosteronism (PA). Pre-AVS cross-sectional imaging does not reduce the need for AVS. The goal of this study was to examine whether performing AVS prior to imaging could decrease the use of imaging in the evaluation of PA at a high volume, experienced center. We performed a retrospective analysis of all AVS procedures (n = 337) done for PA from 2001-2013. Patients whose cross-sectional imaging reports were unavailable (n = 90) or AVS was non-diagnostic (n = 12) were excluded. AVS was performed using modified Mayo technique. Univariate analysis utilized the χ² test and fisher's exact test. Of the 235 patients analyzed, 63% (n = 148) were male. The mean age was 55 ± 11 years. AVS was non-lateralizing in 43% (n = 101); these patients might have avoided imaging with an AVS-first approach. Imaging and AVS were concordant in 52% (n = 123). In patients ≤40yo (n = 23), 35% (n = 8) had no lateralization on AVS, and might have avoided imaging in an AVS-first approach. Imaging and AVS were concordant in 52% (n = 12) of patients ≤ 40yo, versus 52% (n = 111) of patients > 40 yo (P = 0.987). An AVS-first, imaging-second approach could have avoided CT/MRI in 43% of patients. At a high volume, experienced center, performing AVS first on patients with PA may reduce unnecessary cross-sectional imaging studies. © 2015 Wiley Periodicals, Inc.

Full Text Available We studied the presence of antithyroid antibodies in subjects with slight to overt thyroid disfunction. Fifty nine subjects that showed goiter or TSH levels above 5.0 mU/L were included. The percentage of patients with positive anti Thyroid Peroxidase antibodies (anti TPO was 18.63%. From them, 90.9% exhibited goiter along with thyroid dysfunction, whereas only 9.1 % had goiter without thyroid disfunction. There was no patient without goiter that showed anti TPO levels above 100 mUl/ mL.We conclude that thyroid autoimmune disease is very prevalent among our patients, so it must be suspected in subjects with or without goiter, as well as in those with slight thyroid disfunction, because it could progress to overt hypothyroidism.

Ferroelectric materials for FeRAMs; FeRAM yo kyoyudentai zairyo

Studies to utilize bistable spontaneous polarization of ferroelectric materials for non-volatile memory have already been started in the 1950`s. Recently, a possibility was indicated on a high-speed non-volatile RAM (FeRAM) with memory cell configuration combined with switching transistors as in DRAMs. This situation has led to performing very active studies on ferroelectric materials and electrode materials used in ferroelectric film cell capacitors. This paper summarizes the above research and development circumstances, as well as their future problems. On the other hand of having shown excellent fatigue resistance in the SrBi2Ta209(SBT) system, improvement has progressed steadily on the Pb(ZR, Ti)03 (abbreviated to PZT) system, which retains the mainstream position as the ferroelectric material for FeRAMs. Aiming at realizing a high integration FeRAM in the future will require discussions on property changes due to use of lower temperature and micronization in film formation, further improvement in relation with degradation such as in imprint, and elucidation of the mechanism. 31 refs., 3 figs.

Fixed-axis electric sail deployment dynamics analysis using hub-mounted momentum control

Science.gov (United States)

Fulton, JoAnna; Schaub, Hanspeter

2018-03-01

The deployment dynamics of a spin stabilized electric sail (E-sail) with a hub-mounted control actuator are investigated. Both radial and tangential deployment mechanisms are considered to take the electric sail from a post-launch stowed configuration to a fully deployed configuration. The tangential configuration assumes the multi-kilometer tethers are wound up on the exterior of the spacecraft hub, similar to yo-yo despinner configurations. The deployment speed is controlled through the hub rate. The radial deployment configuration assumes each tether is on its own spool. Here both the hub and spool rate are control variables. The sensitivity of the deployment behavior to E-sail length, maximum rate and tension parameters is investigated. A constant hub rate deployment is compared to a time varying hub rate that maintains a constant tether tension condition. The deployment time can be reduced by a factor of 2 or more by using a tension controlled deployment configuration.

2017-10-15

To explore the relationship of motor burden and educational attainment in patients with advanced stage PD. We included 102 consecutive patients who underwent a complete evaluation for DBS surgery, including detailed neuropsychological testing and UPDRSIII in a standardized Levodopa challenge. Years of education (YoE) were calculated as the highest grade attained in secondary school plus years for post-secondary training. The OFF medication UPDRS-III score was associated with YoE (p=0.006; t=-2.82) and age (p=0.007; t=-2.75) in our multivariable linear regression model even while including disease duration (p=0.8; t=0.21), presence of mild cognitive impairment (MCI) (p=0.9; t=0.16) or current IQ (p=0.2; t=1.25) as additional covariables. In a subgroup of 60 patients two years after DBS, the ON/ON UPDRS score was associated with YoE (p=0.01; t=-2.42) and diagnosis of PD dementia (p=0.05, t=1.95), while age (p=0.08, t=1.75), disease duration (p=0.6t=0.48) and LEDD (p=0.3; t=1.05) showed no significant association to ON/ON UPDRS score. We found an inverse correlation between years of education and lower (better) UPDRS -III motor score after adjusting for important covariables. Education may lead to an increased ability to compensate disturbances in basal ganglia circuits affecting not only for cognitive, but also for motor aspects of PD. Thus, educational attainment may play an important role in the concept of motor reserve. Copyright © 2017 Elsevier B.V. All rights reserved.

Full Text Available Hoy en día las exigencias del cliente cada vez son mayores en cuanto a calidad, servicio y precio; es por ello que las tendencias mundiales que actualmente rigen el campo empresarial reconocen que contar con información de costos que les permita conocer cuáles de sus productos y/o servicios son rentables y cuáles no, las lleva a poseer una ventaja competitiva sobre aquellas que no la tienen, pues con dicha información la dirección puede tomar decisiones estratégicas y operativas en forma acertada. De acuerdo con lo anterior, la Clínica de los Remedios requiere de un buen sistema de costos con el cual pueda determinar con exactitud el costo de los productos y/o servicios que ofrece, así como la rentabilidad de los mismos; para ello es indispensable conocer no sólo los insumos y los recursos que requiere el producto y/o servicio, sino también las áreas relacionadas con ellos y las actividades que los involucran. Se pretende diseñar una metodología de costeo ABC y aplicarla como piloto en el área de imaginología, que actualmente desconoce parcialmente el costo de los servicios que ofrece y por ende su rentabilidad. Buscamos que la implantación de la metodología se realice integralmente y en el contexto de un proceso de planeación estratégica que incorpore en forma consistente una gestión administrativa, presupuestal y de costos enfocada por actividades.

La persona como singularidad concreta en la obra de Hans Urs von Balthasar

Full Text Available El presente estudio aborda el concepto de persona de Hans Urs von Balthasar en cuanto singularidad concreta, descubierto a través de una intensa lectura analítica de su voluminosa obra, búsqueda a la luz de la pregunta ¿por qué yo soy precisamente yo? En efecto, el teólogo suizo nunca sistematiza su comprensión de persona ­la distingue sí de los conceptos "individuo", "sujeto" y "espíritu­, pese a que se sirve de aquella como de uno de los pilares más significativos de su pensamiento. Los resultados obtenidos evidencian la complejidad de factores conceptuales, que demuestran que el yo tiene su fundamento último en el acto libre del amor infinito, que como tal constituye la persona desde el dinamismo intradivino de las relaciones opuestas entre Padre, Hijo y Espíritu SantoThis paper regards the concept of person as a concrete singularity in Hans Urs Von Balthasar's work. Such concept rose after a deep analytical reading of his voluminous work, in the light of the guiding question; Why am I, precisely I? The Swiss theologian distinguishes person from the concepts "individual", "subject" and "spirit", but he never synthesises his understanding of person, even though he uses it as one of the most significant pillars of his thought. The results obtained from the research confirm the complexity of the conceptual factors, which show that one's self has its deepest foundation in the free act of the infinite love, which as such, constitutes the person from the intra-divine dynamism of the opposed relations between the Father, Son and Holy Spirit

Purpose: Chronic progressive neuro-Behçet's disease (CPNBD) resembles multiple sclerosis (MS) on patient background and image findings, and therefore is difficult to diagnose. The purpose is to identify the characteristic magnetic resonance imaging (MRI) findings of CPNBD and to clarify the differences between the MRI findings of CPNBD and those of MS. Materials and methods: The subjects consist of a CPNBD group (n = 4; 1 male and 3 females; mean age, 51 y.o.), a MS group (n = 19; 3 males and 16 females; mean age, 45 y.o.) and a normal control group (n = 23; 10 males and 13 females; mean age, 45 y.o.). Brain stem atrophy, cerebellar atrophy, and leukoencephalopathy were retrospectively evaluated in each subjects. In middle sagittal brain MR images, the prepontine distance was measured as an indirect index of brain stem and cerebellar atrophy and the pontine and mesencephalic distance was measured as a direct index of brain stem atrophy. These indexes were statistically analyzed. Results: Brain stem atrophy, cerebellar atrophy, and leukoencephalopathy were seen in all CPNBD cases. Prepontine distance was significantly different between the CPNBD group and the MS group (p < 0.05), and between the CPNBD group and the normal control group (p < 0.001). Pontine and mesencephalic distance were significantly different between the CPNBD group and the MS group (p < 0.001, p < 0.01 respectively), and between the CPNBD group and the normal control group (p < 0.001). Conclusions: Chronic progressive neuro-Behçet's disease should be considered in patients with brain stem and cerebellar atrophy in addition to leukoencephalopathy similar to that seen in multiple sclerosis.

The following tests were conducted to assess CODS and endurance: Agility 505 turning toward the dominant (A505DL and non-dominant lower limb (A505NL; Illinois Agility Test (IAT; and intermittent test (Yo-Yo IRT1. During the soccer season, we investigated performance at the following time periods: the start (t1 and the end of the pre-season period (t2; during (t3 and at the end of the competitive period (t4. Repeated measurement analysis of variance revealed a significant effect of time period on selected fitness parameters (p < 0.05. Post hoc analysis for test A505DL revealed significant improvements of performance at t3 (2.71 ± 0.08 s and t4 (2.72 ± 0.06 s compared to t1 (2.81 ± 0.09 s. A505NL was significantly different between t1 (2.83 ± 0.09 s and t2 (2.76 ± 0.09 s, t3 (2.7 ± 0.07 s and t4 (2.71 ± 0.09 s. Performance of CODS at t1 for the IAT (18.82 ± 0.56 s was significantly lower (p < 0.05 than any other time period (t2 = 18.52 ± 0.63 s, t3 = 17.94 ± 0.51 s, t4 = 17.89 ± 0.66 s. The power of LRS was significantly different at t3 (4.99 ± 0.15 s, and t4 (4.98 ± 0.17 s compared to t1 (5.15 ± 0.21 s, and t2 (5.07 ± 0.14 s. For the Yo-Yo IRT1 test, we observed a significant increase in performance between t1 (625.26 ± 170.34 m, t2 (858.95 ± 210.55 m, and t3 (953.68 ± 229.88 m. These results show the impact of soccer season time period on young soccer player performance and may further serve as a basis for comparison with similar research conducted by peers. These results may aid sports practice for clinicians, conditioning coaches, soccer coaches and physiotherapeutic coaches.

Conocemos desde la perspectiva del psicoanálisis de Freud (en su trabajo sobre Meta psicología en 1915, cómo el instinto es un concepto limítrofe entre lo mental y lo somático, siendo la representación psíquica del estímulo, originado en el organismo que elige la mente.
Por lo tanto los instintos no serían sino la organización de "fuerzas" para la vida y la muerte orgánica, que buscan restablecer un orden y estado de interrelación y movimiento con otras fuerzas (cargas opuestas, antimateria y/o antipartículas, que perturban ese funcionamiento o por el contrario, actúan para conservar el equilibrio y orden; he ahí un concepto proveniente o que nos lleva también a la teoría de la complejidad y caos.

Discussions were given on quality improvement and cost reduction of heating and forming molds for household rubber, plastics and electronic device parts. This paper summarizes the achievements in fiscal 1998. Verification was made on chromium plated steel and stainless steel molds as to improvement in water repellency of the mold surface by injecting N and F ions, improvement in surface hardness by making the surface into CrN and CrF, and improvement in wear resistance. In order to inject the ions uniformly into the mold surface having irregularities, a high-frequency and high-energy power supply was developed. Development was made on a negative voltage induction pulse power supply taking synchronism with the above pulse power supply and a 50-kV field through device. The design and fabrication thereof have been completed and the trial operation has begun. In order to evaluate mold releasing performance and pollution effect on molds under the same conditions for all makes, a unified evaluation criterion was established. With regard to nitriding and chromation by means of nitrogen ion injection into chromium plated steels under the unified rubber composition, the mold releasing performance and pollution effect were evaluated in terms of economics. Residue of rubber material in a mold has decreased, and metal polluting effect has been improved. Quantitative evaluation was performed successfully by the CCD taken image processing of surface images. (NEDO)

Graphical abstract: (a) The averaged distortion index and the Y–O bond length of the Y 2 O 3 octahedra as a function of the simulation time for 5 keV PKA. (b) Shows the nearest neighbourhood of one of the Y ions as a function of simulation time, showing the destruction and the recovery of the YO 6 octahedron during the cascade corresponding to 5 keV Y PKA. - Highlights: • Qualitative difference in displacement cascades exists for Y and O PKA. • Nearest neighbour correlation between Y and O ions exists even at cascade peak. • Cascade core in Y 2 O 3 does not undergo melting. • Topological connectivity of YO 6 polyhedra plays important role in stability of Y 2 O 3 . - Abstract: We study the characteristics of displacement cascades in single crystal Y 2 O 3 using classical molecular dynamics. There are two possible ways to generate the cascades in yttria, using either the Y or the O atoms as the primary knock-on (PKA) atom. It is shown that there is a qualitative difference in the characteristics of the cascades obtained in these two cases. Even though the crystal is seen to be in a highly disordered state in the cascade volume, as seen from the plots of radial distribution function, the correlation between the Y and O atoms is not completely lost. This facilitates a quick recovery of the system during the annealing phase. Topological connectivity of the YO 6 polyhedral units plays an important role in imparting stability to the Y 2 O 3 crystal. These characteristics of the cascades can help explain the stability of the yttria nanoparticles when they are dispersed in oxide dispersion strengthened steels

[OVARIAN RESERVE AND EFFECTIVENESS OF IVF IN WOMEN OF VARIOUS AGE GROUPS].

Sayadyan, A; Totoyan, E

2017-01-01

The purpose of this study is a comparative assessment of ovarian reserve parameters and the effect of these indices on the features of follicle and oogenesis in women of different age groups. A retrospective analysis of IVF results was conducted in 101 patients aged 21 to 49 years. All patients were divided into 4 groups according to age: I group up to 30 y.o. - 45 women, II group - 31-35 y.o - 14 women, III group - 36-40 y.o. - 26 women, IV Group - 41 or more - 16 women. A low ovarian reserve was found in the majority (84,6%) of women in group III and in all women in group IV. It was found that the lowest total dose of rFSH / hMG was used in women aged 21-30 years and 31-35 years, and in women in the age range of 36-40 years, the consumption of drugs was significantly higher and tended to further increase in the age group 41 аnd more years. A large consumption of rFSH/hMG is necessary to overcome the growing FSH level in the process of aging of the reproductive system and the reduced AMH level. However, at the same time, compared age groups had significant differences in the number of oocytes and embryos obtained. With age, a significant reduction in the number of mature oocytes and embryos obtained after follicle puncture and fertilization has been identified. The most promising in terms of pregnancy were the I and II groups. With age, the frequency of pregnancy decreased. The number of pregnancies was statistically lower in the III age group compared to groups I and II. In the IV group, no cases of pregnancy were recorded. Thus, it can be concluded that age is a statistically significant factor affecting the success of infertility treatment by IVF.

Negative attitudes and discrimination against Latinos exist in the dominant U.S. culture and in healthcare systems, contributing to ongoing health disparities. This article provides findings of a pilot test of Yo Veo Salud (I See Health), an intervention designed to positively modify attitudes toward Latinos among medical trainees. The research question was: Compared to the comparison group, did the intervention group show lower levels of implicit bias against Latinos versus Whites, and higher levels of ethnocultural empathy, healthcare empathy, and patient-centeredness? We used a sequential cohort, post-test design to evaluate Yo Veo Salud with a sample of 69 medical trainees. The intervention setting was an academic medical institution in a Southeastern U.S. state with a fast-growing Latino population. The intervention was delivered, and data were collected online, between July and December of 2014. Participants in the intervention group showed greater ethnocultural empathy, healthcare empathy, and patient-centeredness, compared to the comparison group. The implicit measure assessed four attitudinal dimensions (pleasantness, responsibility, compliance, and safety). Comparisons between our intervention and comparison groups did not find any average differences in implicit anti-Latino bias between the groups. However, in a subset analysis of White participants, White participants in the intervention group demonstrated a significantly decreased level of implicit bias in terms of pleasantness. A dose response was also founded indicating that participants involved in more parts of the intervention showed more change on all measures. Our findings, while modest in size, provide proof of concept for Yo Veo Salud as a means for increasing ethno-cultural and physician empathy, and patient-centeredness among medical residents and decreasing implicit provider bias toward Latinos.

In 2 years and 5 months from April 1980 to May 1982, I had maked examination for computed tomography (CT) in head region by TCT-60A (TOSHIBA), and so reported the evaluation of following those results; 1) The number of CT scan was 1228 patients and total 1513 scannings. The contents of its scan were plain CT (86.1%), CE (contrast enhancement) CT (7.3%) and both application methods (6.6%), and included from 1 CT time (85.3%), 2 CT times (9.6%), 3 CT times (3.3%),... til 7 CT times. Our CT scan cases were 720 males (58.6%) and 508 females (41.4%);its scan age level was mostly 40 y.o. -- over 70 y.o., but low age patients (under 10 y.o.) indicated number of 15.3%. In consideration of this fact the advantage of CT scan was very easily and safely procedure free from body lesion. 2) In number of CT scan: the most many patients were visiting department of internal medicine clinic, and following pediatric clinic, surgery and orthopedic department. Above all CT scan cases were included of other all clinical departments in our hospital. (CT scan was very useful for neurological examination). 3) In CT diagnosis our cases were it of cerebral infarction 128 (10.4%), cerebral hemorrage 19 (1.5%) and brain tumor 24 (2.3%), in small cases other craniocerebral diseases. 4) The visiting cases in internal medicine often complain of cerebrovascular symptomes, and in pediatric clinic chief complain was often suspected mental retardation and neurological sign. In surgery department it was suspected metastatic brain tumor from other malignant cancers, and in orthopedic surgery often skull injury or traffic accident. (J.P.N.)

This paper presents a Multi-satellite Data Analysis and Simulator Tool (MDAST), developed with the original goal to support the science requirements of a Martian 3-Unit CubeSat mission profile named Bleeping Interplanetary Radiation Determination Yo-yo (BIRDY). MDAST was firstly designed and tested by taking into account the positions, attitudes, instruments field of view and energetic particles flux measurements from four spacecrafts (ACE, MSL, STEREO A, and STEREO B). Secondly, the simulated positions, attitudes and instrument field of view from the BIRDY CubeSat have been adapted for input. And finally, this tool can be used for data analysis of the measurements from the four spacecrafts mentioned above so as to simulate the instrument trajectory and observation capabilities of the BIRDY CubeSat. The onset, peak and end time of a solar particle event is specifically defined and identified with this tool. It is not only useful for the BIRDY mission but also for analyzing data from the four satellites aforementioned and can be utilized for other space weather missions with further customization.

Full Text Available Amputee football is a variation of conventional soccer in which athletes with lower limb amputation and one athelete with upper limb amputation (the goalkeeper participate. The objective of this study was to investigate the anthropometric and physical characteristics of amputee football athletes and to verify differences between heart rate peak (HRpeak and equations for predicting maximum heart rate (HRmax. Twelve amputee soccer players from the Brazilian team participated in this study. The body mass, height and body composition were measured. The physical tests used were: the 20 m running test, the T-square test and the Yo Yo intermitent recovery test - level 1 (YYIRT1. The percentage of fat was significantly different between midfielders and defenders. No significant differences were found between positions in the physical tests. The HRpeak was significantly lower than all of HRmax prediction equations tested. We conclude that the indicators of physical performance did not differ significantly between the different tactics roles of players, and that, after intermittent maximum effort, the cardiac response was lower when compared with the investigated HRmax prediction equations.

Highlights: {yields} Pure Wuestite (Fe{sub 1-y}O) nanoparticles synthesized by organometallic chemistry. {yields} The influence of the surface ligands on the magnetic properties. {yields} Ferromagnetic core-antiferromagnetic shell magnetic nanoparticles. - Abstract: Wuestite particles (Fe{sub 1-y}O) are synthesized using controlled hydrolysis at room temperature of [Fe(N(SiMe{sub 3}){sub 2}){sub 2}] and stabilized by amine ligands. This method leads to 5 nm pure wuestite particles. This phase is clearly identified by transmission electron microscopy and wide angle X-ray scattering. Distortion in the crystallographic structure has been demonstrated. Particular attention is paid on the Fe(III) formation. Moreover, a combination of Moessbauer spectroscopy and SQuID measurements, revealed that the particles are composed of an antiferromagnetic core surrounded by a ferromagnetic shell. According to the Neel theory, the Fe(III) and Fe(II) ions present in the particles are ferromagnetically coupled and the proportion of Fe(III) ions varies from 3.9 to 7.1% as a function of the amine ligand.

Full Text Available The role of vertical barotropic and baroclinic tidal forcing in the aggregation and dispersion of ichthyoplankton in the Southern Gulf of Mexico was analyzed in this study. Samplings of ichthyoplankton and the determination of hydrographic parameters were performed during September 1992 at a single point of 180 m depth, near the shelf break (19º32'N - 92º38.5'W. A 24 h CTD yo-yoing casting and biological samples were taken every 2 h and these measurements were combined with water velocity and density simulations from the Regional Ocean Model System (ROMS. One thermocline and two haloclines were depicted. The Froude number increased with a 2 h lag with respect to the maximal barotropic tide, suggesting the existence of a baroclinic tide. Aggregation and dispersion of the ichthyoplankton showed vertical oscillations in the abundance and the numbers of taxa and larvae with a 5 h lag with respect to the maximal barotropic tide and were in phase with the thermocline oscillation. The vertical oscillation was attributed to a hydraulic control forced by the internal tide.

Yo-Yo-Ma, the Chicago and Boston Symphony Orchestras, Ravi Coltrane, Esperanza Spalding, Phish, Blood Sweat and Tears, Deep Purple, Tony Orlando, and Wilco performed at these events. MAUS combines solar, optical, and radio telescope observations; large posters/banners (From the Earth to the Universe; Visions of the Universe); videos; hands-on activities (Night Sky Network; Harvard-Smithsonian CfA); imaging with a cell phone mount; and hand-outs (info on science museums, astronomy clubs, and citizen science) before and after the concerts or at intermission. MAUS reached underserved groups and attracted large enthusiastic crowds. Many young children participated in this family learning experience-often the first time they looked through a telescope. Outcomes: While education!

Reacciones y protestas de agricultores e inmigrantes en El Ejido: un municipio español inserto en las dinámicas de la globalización

Full Text Available El Ejido es una ciudad del sudeste español que ha pasado de ser una pequeña aldea dedicada a la agricultura de subsistencia, a principios de 1960, a tener en 2015 más de 85.000 habitantes. Este cambio se debe al desarrollo de una economía de invernaderos muy próspera que hoy está totalmente inserta en las dinámicas de la globalización. Tales dinámicas han ocasionado efectos contradictorios y han suscitado reacciones y/o formas de protesta diferentes en los dos principales actores sociales de El Ejido (los agricultores y los inmigrantes, entre los que se observan profundas asimetrías socioeconómicas y relaciones de explotación laboral. Como consecuencia, los inmigrantes y los agricultores viven en dos mundos sociales completamente diferentes y tienen percepciones y actitudes opuestas sobre la realidad, las cuales, a su vez, afectan a sus respectivas posibilidades y modos de reacción y/o de protesta.

The aim of this study was to compare the training effects based on repeated sprint ability (RSA) (with one change of direction) with an intensive repeated sprint ability (IRSA) (with two changes of direction) on jump performance and aerobic fitness. Eighteen male basketball players were assigned to repeated sprint ability and intensive repeated sprint ability training groups (RSAG and IRSAG). RSA, IRSA, squat jump (SJ), countermovement jump (CMJ) and Yo-Yo intermittent recovery level 1 test were assessed before and after four training weeks. The RSA and IRSA trainings consisted of three sets of six sprints (first two weeks) and eight sprints (second two weeks) with 4-min sets recovery and 20-s of sprints recovery. Four weeks of training led to an overall improvement in most of the measures of RSA, but little evidence of any differences between the two training modes. Jump performance was enhanced: CMJ of 7.5% (P training with one/two changes of direction promotes improvements in both RSA and IRSA respectively but the better increase on jump performance shown a few changes on sprint and endurance performances.

The physical-performance profiles of subelite male footballers were monitored during 6 wk of a competitive season. The same squad of players played either 1 (1G, n = 15) or 2 (2G, n = 15) competitive matches per week. On weeks 0, 3, and 6, 48 h postmatch, players completed countermovement jump (CMJ), 10- and 20-m sprints, the Yo-Yo Intermittent Recovery Test (YYIRT), and the Recovery-Stress Questionnaire. Both groups undertook 2 weekly training sessions. The 2G showed after 6 wk lower YYIRT (-11% to 3%, 90% CI -15.8% to -6.8%; P m (4.4%, 1.8-6.9%; P = .007) and 20-m sprints values (4.7%, 2.9% to 6.4%; P < .001). No differences were found at 3 wk (.06 < P < .99). No changes over time (.169 < P < .611) and no differences time × group interactions (.370 < P < .550) were found for stress, recovery, and the Stress Recovery Index. In conclusion players' ability to sprint, jump, and perform repeated intense exercise was impaired when playing 2 competitive matches a week over 6 wk.

Urchin-like KxCoyMn8-yO16 hollow spheres assembled from nanoplate building blocks were successfully fabricated via a one-pot hydrothermal route using cobalt acetate and potassium permanganate as raw material. The products were characterized by powder X-ray diffraction (XRD), Fourier transform infrared (FT-IR) spectrometer, field-emission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM) and high resolution transmission electron microscopy (HRTEM) measurement. The thermal stability and surface areas of cobalt ion in the manganese sites of KMn8O16 structures were clearly evidenced by TGA and N2 adsorption-desorption isotherms curves. Based on time depended experiment results, a possible formation mechanism for this structures was proposed. The catalytic degradation of Rhodamine B (RhB) on KxCoyMn8-yO16 materials has, therefore been dependent for the molar precursor ratio and specific surface area of the as-fabricated products. UV-vis, LC-MS and barium hydroxide methods were utilized to monitor the temporal course of the catalytic reaction.
