RELATIONSHIPS BETWEEN CRICKET FAST BOWLING TECHNIQUE, TRUNK INJURIES, AND BALL RELEASE SPEED

The Australian Institute of Sport Biomechanics department cricket fast bowling technique data were analysed to: (1) identify the critical technique factors associated with trunk injuries and (2) identify any technique factors associated with a higher ball release speed. Shoulder counter-rotation was significantly higher for lumbar spine stress-fractured bowlers than non trunk-injured bowlers. The stress fractured bowlers were also characterized by a larger hip angle in the sagittal plane at front foot contact and ball release, whereas a more flexed front knee at ball release characterized the non trunkinjured bowlers. A series of weak but significant relationships were evident between kinetic and kinematic technique characteristics and higher ball release speeds

Battlezone: An examination of the physiological responses, movement demands and reproducibility of small-sided cricket games

As cricket training typically involves separate skill and conditioning sessions, this study reported on the movement demands, physiological responses and reproducibility of the demands of small-sided cricket games. Thirteen amateur, male cricket players (age: 22.8 ± 3.5 years, height: 1.78 ± 0.06 m, body mass: 78.6 ± 7.1 kg) completed two sessions of a generic small-sided cricket game, termed Battlezone; consisting of six repeat 8-over bouts. Heart rate and movement demands were continuously recorded, whilst blood lactate concentration and perceived exertion were recorded after each respective bout. Batsmen covered the greatest distance (1147 ± 175 m) and demonstrated the greatest mean movement speed (63 ± 9 m · min-1) during each bout. The majority of time (65-86%) was spent with a heart rate of between 51-85% HRmax and a blood lactate concentration of 1.1-2.0 mmol · L-1. Rating of perceived exertion ranged between 4.2-6.0. Movement demands and physiological responses did not differ between standardised sessions within respective playing positions (P > 0.05). The reliability for the majority of movement demands and physiological responses were moderate to high (CV: 5-17%; ICC: 0.48-1.00) within all playing positions. These results suggest that the physiological responses and movement characteristics of generic small-sided cricket games were consistent between sessions within respective playing positions. © 2013 Copyright Taylor and Francis Group, LLC

Separação e caracterização dos componentes de hemoglobina de Pterygoplichthys pardalis, o acaribodó

The four main hemoglobin components of the hemolysate of Pterygoplichthys pardalis have been isolated and characterized. The functional properties investigated for the isolated components comprise the effect of pH and ATP on (i) the O2 equilibrium, (ii) the O2 dissociation kinetics, (iii) the CO combination kinetics. Component I, corresponding to approximately 50% of the total hemoglobin, is characterized by functional properties which are distinctly different from those of Components II, III and IV, which are alike. Thus it is shown, once more, that multiple components in an hemolysate fall into categories of hemoglobins characterized by distinct and complementary functional properties.Os quatro componentes de hemoglobina principais do hemolisado de Pterygoplichthys pardalis foram isolados e caracterizados. As propriedades funcionais investigadas para os componentes isolados compreendem o efeito de pH e ATP sobre(i) o equilíbrio de O2, (ii) a cinética da dissociação de O2 (iii) a cinética da combinação de CO. O componente I, corresponde a aproximadamente 50% da hemoglobina total, é caracterizado por propriedades funcionais que são diferentes das dos componentes II, III e IV, os quais são semelhantes. Assim, é provado, uma vez mais, que componentes múltiplos num hemolisado caem na categoria de hemoglobinas caracterizadas por propriedades funcionais distintas e complementares

Los tesoros ocultos del Museo del Prado

Looking at the Madonna by Antonello of Messina in the Palazzo Abatellis in Palermo, we are faced with (at least) three questions. Is the Virgin of the Annunciation, the Immaculate Mother of God who is about to receive the news that she is going to carry the Son of God in her womb? Or is it a portrait, perhaps of a person we know or could know? But does it matter? No. What matters is that we respond to her as if she were a human being, not a divine or transcendent being, as if she were someone we could meet, even in our wildest dreams. What matters is that almost instantly it arouses our interest, that with the right hand it seems to force us to stop, that we are drawn to the face, beautiful and mysterious, and that we recognize in it someone whose feelings we thought we might understand, someone whose emotional state we could access. Immediately, as soon as we set our sights on it, we feel involved; immediately we notice the shadow that crosses the forehead and the left eye, as well as, in the right half of the face, the slight pout of the mouth, sensual but at the same time enigmatic.' What does all this mean? You have been reading; is raising his hand right now, as if requesting a pause, reflecting, no doubt, on something he has just seen

Though ubiquitous, “destructive fishing” is undefined and therefore currently immeasurable. Here we propose a definition developed through expert consultation: “Destructive fishing is any fishing practice that causes irrecoverable habitat degradation, or which causes significant adverse environmental impacts, results in long-term declines in target or nontarget species beyond biologically safe limits and has negative livelihood impacts.” We show strong stakeholder support for a definition, consensus on many biological and ecological dimensions, and no clustering of respondents from different sectors. Our consensus definition is a significant step toward defining sustainable fisheries goals and will help interpret and implement global political commitments which utilize the term “destructive fishing.” Our definition and results will help reinforce the Food and Agricultural Organization's Code of Conduct and meaningfully support member countries to prohibit destructive fishing practices.Cambridge Conservation Initiative.
