Peripheral Nerve Responses to Muscle Stretching: A Systematic Review
2021
Stretching is commonly used to increase range of motion and flexibility. Therefore, investigations are usually oriented towards the muscle-tendon unit. Limited evidence exists regarding potential effects of stretching on peripheral nerves which lie within muscles. The objective of this investigation will be to elucidate the responses of peripheral nerves to stretching. A literature search was performed using the following databases: Scopus, NLM Pubmed and ScienceDirect. Studies regarding the effects of stretching protocols on responses of peripheral nerves were retrieved for investigation. The NHLBI tool was used for quality assessment. Outcomes included nerve stiffness, nerve displacement,…
Ecological Stoichiometry of Bumblebee Castes, Sexes, and Age Groups
2021
Ecological stoichiometry is important for revealing how the composition of chemical elements of organisms is influenced by their physiological functions and ecology. In this study, we investigated the elemental body composition of queens, workers, and males of the bumblebee Bombus terrestris, an important pollinator throughout Eurasia, North America, and northern Africa. Our results showed that body elemental content differs among B. terrestris castes. Young queens and workers had higher body nitrogen concentration than ovipositing queens and males, while castes did not differ significantly in their body carbon concentration. Furthermore, the carbon-to-nitrogen ratio was higher in ovipositi…
Perfil de la educación física y sus profesores desde el punto de vista de los alumnos. (Physical education and their teachers’ profile from the pupil…
2007
El objetivo de este trabajo ha sido conocer el pensamiento de los alumnos sobre la Educacion Fisica y sus profesores. Para ello, 788 estudiantes de Educacion Secundaria Obligatoria (337 alumnos y 451 alumnas) han respondido a un cuestionario abierto en el que se les preguntaba que es lo que mas y lo que menos les gusta de EF, como se imaginan a su profesor/a ideal de EF, y las tres caracteristicas mas importantes que deberia tener su profesor o profesora de EF. Tras un analisis de contenido de las respuestas de los alumnos se concluye que las cosas que mas les gustan de EF son las practicas de deportes de equipo y los juegos y actividades variadas; las cosas que menos les gustan son los eje…
Los libros de texto de educación física en la etapa de educación primaria: análisis de imágenes y estereotipos
2020
En investigaciones anteriores se ha podido comprobar que las imágenes que aparecían en los libros de texto de educación física (EF) en el tercer ciclo de educación primaria (EP) reproducían estereotipos relacionados con el género, la edad, el cuerpo, la raza o la discapacidad, en relación con la actividad física. Por ello se necesita ampliar la muestra y analizar este material curricular para comprobar si se han eliminado los estereotipos relacionados con el cuerpo y la actividad física o siguen presentes en los libros de texto. Por lo tanto, el objetivo general de esta tesis doctoral es analizar las imágenes relacionadas con los estereotipos corporales en la actividad física que aparecen e…
The Relationship between Motivational Climate and Personal Treatment Satisfaction among Young Soccer Players in Norway: The Moderating Role of Suppor…
2020
Motivational climate and coach-behaviour seem important to understand sport involvement and participation. However, less is known about the potential interaction between these facets, and how it relates to athlete satisfaction. This study&rsquo
Evaluating the importance of Marine Protected Areas for the conservation of hawksbill turtles Eretmochelys imbricata nesting in the Dominican Republic
2015
Understanding spatial and temporal habitat-use patterns to protect both foraging and breeding grounds of species of concern is crucial for successful conservation. Saona Island in Del Este National Park (DENP), south-eastern Dominican Republic (DR), hosts the only major hawksbill (Eretmochelys imbricata) nesting area in the DR (100 nests yr �1 , SD = 8.4, range = 93�111), with the population having been critically reduced through hunting. We satellite tracked 9 female hawksbill turtles, and present analyses of their core-use areas with respect to Marine Protected Areas (MPAs) in both their internesting and foraging areas. Kernel utilization distribu- tions indicated that during the internes…
Distribution, ecology and conservation status of Dionysia involucrata Zaprjag., an endangered endemic of Hissar Mts (Tajikistan, Middle Asia)
2014
<em>Dionysia involucrata</em> Zaprjag. (Primulaceae) is known as critically endangered endemic species of Hissar Mountains in Tajikistan. It is reported from few localities mainly in Varzob River valley and its tributaries. The species inhabits steep or overhanging faces of granite rocks in narrow river gorges. During the research all known populations of <em>D. involucrata</em> were examined in respect of the habitat conditions and species composition of vegetation plots. We analyzed the population extent of the species in its range in Tajikistan and the main threats in order to assess its conservation status. The detrended correspondence analysis was performed on a…

Complete One-Loop Renormalization of the Higgs-Electroweak Chiral Lagrangian
2018
The electroweak sector of the Standard Model can be formulated in a way similar to Chiral Perturbation Theory (ChPT), but extended by a singlet scalar. The resulting effective field theory (EFT) is called Higgs-Electroweak Chiral Lagrangian (EWCh$\mathcal{L}$) and is the most general approach to new physics in the Higgs sector. It solely assumes the pattern of symmetry breaking leading to the three electroweak Goldstone bosons (i.e. massive $W$ and $Z$) and the existence of a Higgs-like scalar particle. The power counting of the EWCh$\mathcal{L}$ is given by a generalization of the momentum expansion of ChPT. It is connected to a loop expansion, making the theory renormalizable order by ord…
Six-dimensional measurements of trains of high brightness electron bunches
2015
Trains of ultrashort electron pulses with THz repetition rate, so-called comblike beams, are assuming an ever growing interest in plasma-based acceleration. In particle-driven plasma wakefield acceleration (PWFA), a train of driver bunches with separation of the order of plasma wavelength, i.e., 300 μm, resonantly excites a plasma wake, which accelerates a trailing witness bunch, injected at the accelerating phase. Comblike beams have great potentialities in different fields of applications. In particular, radiation sources, such as free-electron lasers and THz radiation, take advantage from the possibility to tailor electron beams modulated both in time and energy, to customize emission ba…
