Resumo Neste artigo é proposto a utilização de um jogo didático como complementação metodológica para ensinar Física de altas energias, abordando a temática de Física de Partículas Elementares. A ideia é utilizar estratégias lúdicas e divertidas para ensinar fenômenos estudados no Grande Colisor de Hádrons (LHC), levando os participantes a fazerem novas descobertas didático-científicas, adquirir conhecimento e construírem conceitos que serão utilizados na formulação da teoria do bóson de Higgs e de sua detecção no experimento ATLAS. Embora tais conceitos tenham uma descrição quantitativa extremamente complexa, até certo ponto arraigada a uma análise experimental, é possível torná-la qualitativamente acessível sem precisar recorrer a formulações matemáticas avançadas, conservando, entretanto, seu caráter técnico.

Abstract In this article it is proposed the use of a didactic game as a methodological complementation to teach High Energy Physics, addressing the theme of Elementary Particle Physics. The idea is to use playful and fun strategies to teach phenomena studied in the Hadron Large Collider (LHC), leading the participants to make new scientific discoveries, acquire knowledge and construct concepts that will be used in the formulation of the Higgs boson theory and its detection in the ATLAS experiment. Although such concepts have an extremely complex quantitative description, to some extent rooted in experimental analysis, it is possible to make it qualitatively accessible without having to resort to advanced mathematical formulations, while retaining its technical character.

Resumen Los equinos deportivos, son víctimas de frecuentes heridas en la región distal de los miembros y de fracturas articulares. La medicina regenerativa es un campo emergente el cual utiliza métodos alternativos para diferentes lesiones de difícil resolución con tratamiento convencional. Existen antecedentes que utilizan parches de fibrina (PF) en la reparación de heridas cutáneas y plasma rico en plaquetas (PRP) en lesiones osteoarticulares. Este trabajo tuvo por objetivo evaluar la aplicación de PRP sobre una fractura de tercer carpiano del miembro anterior derecho y la aplicación de PF en una herida de 54 cm² en la región metatarsiana del miembro posterior izquierdo de un equino Sangre Pura de Carrera (SPC). Se realizó una única aplicación PRP mediante artrocentesis intercarpiana. Sobre la herida cutánea, se realizaron 3 aplicaciones (1 por semana) de PF. Un mes post-aplicación de PRP el equino ya no evidenciaba claudicación, no manifestaba dolor ni inflamación articular y no rechazaba el apoyo. A nivel radiográfico, se observó consolidación de la línea de fractura, con remodelación ósea. A su vez, luego de la tercera aplicación de PF (3 semanas), la superficie de la herida se redujo dos tercios del tamaño original y a las 8 semanas se logró su completa resolución

Abstract Distal limb wounds and joint fractures are very frequent in sport horses. Regenerative medicine is an emerging field that uses alternative methods for healing injuries that are difficult to solve with conventional treatment. Fibrin glue (FG) patches have been used for skin wound repair and platelet rich plasma (PRP) to heal musculoskeletal injuries. The aim of this work was to assess the effect of regenerative medicine therapies in a joint and skin injure on a racehorse. A female thoroughbred horse had a slab fracture in carpal III bone of the right forelimb and a 54-cm2 wound in the metatarsal region of the left hind limb. PRP was applied into the intercarpal joint by arthrocentesis. Three applications (once per week) of FG were performed on the wound. A month after PRP application, the horse showed no lameness, pain or joint swelling. Radiographs showed a consolidated fracture with bone remodeling. As to the wound, after the third FG (3 weeks), its surface was reduced two-thirds of the original size and 8 weeks later, it achieved full resolution

The group contribution with association equation of state GCA-EOS has been applied to calculate thermodynamic properties of pure compounds and mixtures of carboxylic acids with paraffins, alcohols, water and gases, at low and high pressures. Two associating groups, OH and COOH, were defined. Self- and cross-association in these mixtures were quantified through two parallel COOH/COOH and OH/OH associations. The validity of this approach is supported by an excellent representation of pure compound properties (vapor pressures and compressibility factors) and phase equilibria in mixtures of (associating + inert) and (associating + associating) components at low and high pressures.

Inverse gas-liquid chromatography has been applied to measure infinite dilution activity coefficients (g¥ ) of different solutes in low and high molecular weight triacylglycerides (TAGs) and in mixtures of carboxylic acids with TAGs. The g¥ data obtained were used to determine binary interaction and size related parameters for the GCA-EOS group contribution with association equation of sate.
