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,…
Crystal growth and characterization of Zn1-xMgxO advanced micro- and nanostructures
2018
Dentro de la creciente área de investigación de la física de semiconductores, los pertenecientes a la familia II-VI se han convertido en un campo fundamental de la física de materiales debido a que sus propiedades fotofísicas son únicas para crear una nueva generación de dispositivos en el campo de la fotónica y la microelectrónica. Entre ellos, los semiconductores basados en ZnO han ganado un considerable interés en la comunidad científica en parte debido a su alta energía de enlace del excitón (60 meV) la cual es 2.4 veces más alta que la energía térmica a temperatura ambiente. Este hecho puede dar lugar a emisión laser excitónica a temperaturas incluso mayores que la ambiente. Además, gr…
Dual Information Systems: Supporting Organizational Working and Learning by Making Organizational Memory Transparent
1999
The conceptual design of most computer-based information systems reflects a dualism of technology. During the development phase, part of the work-domain-related knowledge is formalized and encoded in the software, making it difficult for users to reflect on and use this knowledge. This design--use dualism contributes to the deterioration of the interpretive flexibility of information systems. In this article, we outline an information systems architecture called Dual Information Systems (DIS) that incorporates the concepts of an organizational memory information system (OMIS) in a broader framework. DIS help bridge the design--use dualism by providing organizations with a set of services th…
Influence of pasteurization temperature on flesh firmness of table olives cv. Nocellara del Belice
2013
The application of heat treatment is especially important in maintaining the organoleptic characteristics of fermented agro-food products, which potential consumers perceive as reflecting the quality of these foodstuffs. The aim of this study was to evaluate the influence of pasteurization time and temperature on the flesh firmness of table olives cv. Nocellara del Belice, packaged in glass jars, and to study their effect on the microbial community of table olives. Four different treatments were applied, one for each of the pasteurization temperatures adopted: 65 °C, 75 °C, 85 °C and 95 °C. A control test was also carried out (test Tc, not pasteurized). Each test was repeated with treatment…
ESR study of thianthrenium radical cation within acid zeolites
1997
Abstract Thianthrene (E ox = 1.47 V vs NHE) has been adsorbed into a series of zeolites beta (s) and ZSM-5 in the NH 4 + or H + forms, having different particle size and Si/Al ratio. The resulting population of generated thianthrenium radical cation was determined by a combination of diffuse reflectance and ESR spectroscopies. From the results obtained it can be concluded: i) the process takes predominantly place in the interior of the voids (XPS measurements and lack of influence of the particle size); ii) ZSM-5 is more efficient than zeolite s; iii) no strong acid sites are required (both NH 4 + and H + forms produced very similar spin concentrations); iv) the zeolite framework acts isola…
The [Fe(etz)6](BF4)2 Spin-Crossover System—Part One: High-Spin ⇌ Low-Spin Transition in Two Lattice Sites
1996
The [Fe(etz),](BF,), spin-cross-over system (etz = 1-ethyl-1 H-tetrazole) crystallizes in space group P1, with the following lattice constants at 298 K: a 10.419(3), b=15.709(1), c = 18.890(2) A = = 71.223(9), =77.986(10), and = 84.62(1)° V = 2862.0(9) A3 and Z = 3. Two nonequivalent lattice sites, one without (site A) and one with (site B) inversion symmetry, are observed. The population of the two sites nA:nB is 2:l. Iron(II) on site A undergoes a thermal low-spin (LS) high-spin (HS) transition with T1/2I, = 105 K. whereas that on site B remains in the high-spin state down to cryogenic temperatures. Application of external pressure of up to 1200 bar between 200 and 60 K does not cause for…
Survival Rates of Young MagpiesPica picain a Mountain Population of Eastern Spain
2007
Abstract. The aim of this study was to estimate the survival of young Magpies between fledging and the next breeding season and to identify some of the factors affecting it. A total of 50 nestlings were colour-ringed in two breeding seasons in the valley of the Pitarque River (Teruel, E Spain), and were monitored weekly until May of the following year. 59 nestlings were also colour-ringed in two nearby localities (4–5 km) to detect possible dispersal to and from our study area. Mark-recapture analyses were used to estimate weekly survival, which was assumed to be constant for periods of four weeks in order to reduce the number of parameters. Models with the effect of time, age class, season…
Sex and population variation in ultraviolet reflectance of colour patches in Gallotia galloti (Fam. Lacertidae) from Tenerife (Canary Islands)
2005
Sex and population differences in the ultraviolet (UV) reflectance patterns of two phenotypically divergent lacertids from Tenerife, Gallotia galloti eisentrauti and G. g. galloti, are described. Adults in both populations have rows of lateral and ventro-lateral blue patches on either side of the trunk that show a single peak of reflectance in the near UV. The lateral patches of males are more intensely reflective than those of females, but females have more chromatic and UV-shifted lateral patches than males. Most G. g. eisentrauti and some G. g. galloti also have blue cheek patches on either side of the gular area. Male cheek patches have reflectance peaks in the near UV, whereas those of…
Ricerca com-partecipata e sperimentazione didattica in campo educativo
2022
Il saggio riflette sulla specificità della ricerca educativa e la accomnuna alla ricerca in campo sociale; ritrova infatti le connessioni nel valore politico, nelle ricadute sulla prassi, e nella prospettiva etica. In questo senso viene evidenziata la possibilità di connettere teoria, metodologia ed esperienza (e, ad un livello meta, di riflettere su tale connessione) e il fatto che questo processo si configura nei termini di una “apprendimento continuo”, sui piani individuale, di gruppo, istituzionale. Ritrovando l’origine di tale prospettiva nell’opera di Dewey (1929), viene quindi evidenziato lo stretto raccordo tra esperienza e pensiero, riflessione e pratica, presente in ogni processo …
Algorithms and Logic as Programming Primers
2019
To adapt all-immersive digitalization, the Finnish National Curriculum 2014 (FNC-2014) ‘digi-jumps’ by integrating programming into elementary education. However, applying the change to mathematics teachers’ everyday praxis is hindered by a too high-level specification. To elaborate FNC-2014 into more concrete learning targets, we review the computer science syllabi of countries that are well ahead, as well as the education recommendations set by computer science organizations, such as ACM and IEEE. The whole mathematics syllabus should be critically viewed in the light of these recommendations and feedback collected from software professionals and educators. The feedback reveals an imbalan…
