Estas narrativas fueron construidas a partir de autoentrevistas, realizadas en el contexto de la crisis sociopolítico-sanitaria que afecta al mundo tras la declaración de pandemia por SARS-CoV-2. A partir de la invitación a contar una experiencia de encierro del pasado, del presente e imaginarios futuros, se exploran en clave temporal las vivencias de distintas generaciones sobre sus encierros y se promueve una reflexividad acerca de los procesos de crisis y las vivencias que estos adquieren para las generaciones jóvenes.

In this context, it is important to develop new protocols to characterise the mineralogical variability of archaeological copper ores. A comprehensive and representative methodology in the analysis of minerals, the application of non-destructive analytical techniques, and the combination of insights from geological, archaeological and local knowledge are key to developing a copper mineral repository of the Atacama Desert area. Geochemical analyses were applied to the study of 568 samples from the archaeological site Pukara de Turi, with different techniques such as micro-XRF, XRD, QEMSCAN, Raman spectroscopy and technological studies. This exhaustive analysis allowed for the recognition of two mineralogical associations: atacamite/brochantite (99%) and azurite/chrysocolla (1%). The study of various mine...

If psychological well-being is considered one of the factors that facilitates adhesion to exercise and health and allows physical exercise to be practiced, adequately perceiving indicators of well-being should be teachers' main objective in teaching physical education at school. We aimed to establish the correspondence between teaching styles in physical education teachers for organising classes and the indices of psychological well-being perceived by students in learning contexts. We conducted a correlational descriptive study between teaching styles indicators (n = 15) using the Styles Questionnaire Educational Profiles (PEE) (Magaz and Garcia, 1998) and the perceptions of subjective well-being by students (n = 150) between 12 and 16 years of age using the Spanish version of Ryff's Scale of Psychological Well-Being (Diaz et al., 2005), corresponding to compulsory secondary education. The data analysis suggests a positive correspondence between the indices of psychological well-being perceived by the students with the way in which their physical education teachers taught the subject. The results showed the importance of the pedagogical transmission of physical activity as a model that encourages adolescents' psychological well-being as a basis for healthy behaviours in adulthood.

TÍTULO: Quinoa Experimentation and Production in Turkey *Corresponding author: Attila YAZAR yazarat@cu.edu.tr ATTILA YAZAR1; ÇIĞDEM INCEKAYA1; METIN SEMIH SEZEN2; SERVET TEKIN3. 1Irrigation and Agricultural Structures Department, Çukurova University, Adana, Turkey 2Water Management Division, Soil and Water Resources Unit in Tarsus, Alata Horticultural Research Institute, Mersin, Turkey 3Biosystem Engineering Department, Sütçüimam University, Kahramanmaraş, Turkey The purpose of this chapter is to provide information on improving food crop production in the arid and semi-arid regions especially in the semi-arid Mediterranean region of Turkey, influenced by multiple abiotic stresses, by strengthening a diversified crop production and introducing new climateproof crops and cultivars with improved stress tolerance such as quinoa. These stresses are becoming even more pronounced under changing climate, predicted to result in drier conditions, increasing temperatures, and ...

In this paper, experimental data related to the AFPMSM used in an electric traction motor was monitored. The paper presents tracing of machine performance in order to find quality-related issues and to evaluate the assembly process. To assess the manual manufacturing process (low-volume production) and electrical machine performance, several motors, characterized by the same size and topology, were extensively tested. Useful AF PMSM parameters such as continuous torque and continuous current were measured. The winding temperature of the stators was also monitored and carefully examined. An attempt to assess motor performance, based on measurements and aimed at the identification of the weakest parts of the electric motor design is presented. In this paper it can be seen how the subcompon...

La muestra está compuesta por jóvenes (N=119) con edades comprendidas entre 11 y 19 años, administrando cuestionarios de medida de la personalidad (NEO-FFI) y estrategias de afrontamiento (CSI). Los resultados muestran que los chicos presentan una media superior tanto en el manejo adecuado como en el manejo inadecuado de estrategias de afrontamiento, que las chicas. Además, puntúan más alto en las estrategias de afrontamiento de autocrítica; apoyo social, reestructuración cognitiva, evitación de problemas y retirada social, mientras que las chicas puntúan más alto en resolución de problemas, pensamiento desiderativo y expresión emocional.

At the same time, should be paid attention to those that facilitate a useful information and applicability to sports performance, trying offer direct feedback to the sports practices. Objective. Describe and establish relations between personality signals and contextuals situations regarding make decisions in sport practice. Method. A study was done with a random sample of athletes (N = 623) between 16 and 50 years old, using personality (BFQ) and make decisions (CETD) questionnaires. Results. Perseverance is shown as the most characteristics indicator of sample; women indicate highest rates in personality dimensions, least in control emotions and openness to culture. Profession...

El estudio presenta una muestra de 421 adolescentes de ESO y Bachillerato de la ciudad de Cartagena (Murcia, Espana). Se utilizaron cuestionarios sociodemograficos, la Escala de Motivacion Educativa (EME-S) y diferentes calificaciones escolares. Los resultados indican que los adolescentes activos tienen valores mas bajos en consumo de alcohol, tabaco y cannabis. Ademas presentan niveles mas altos de motivacion academica y un mejor rendimiento academico en las tres materias analizadas, matematicas, lengua y educacion fisica. La practica de actividad fisico-deportiva en adolescentes se asocia a niveles mas bajos de consumo de sustancias saludablemente, nocivas asi como con mayor rendimiento academico y ...

La muestra (N=71), recogida aleatoriamente entre estudiantes de educación secundaria, compañeros de alumnos con discapacidad, con edades entre 12 y 18 años (M=14.57; DT=1.51). Con una metodología mixta, utilizando cuestionarios sobre cambio de actitudes y creencias hacia la discapacidad, y entrevistas a profesionales del entorno escolar (N=6), para contrastar la información obtenida en la parte cuantitativa. Aparecen altos valores de creencias hacia la discapacidad a favor de los chicos, mientras que las chicas muestran mayores actitudes hacia sus compañero/as discapacitado/as. De la misma forma, conforme aumentan las creencias hacia la integración, disminuyen el reconocimiento y la implicación, por lo que se reduce la intencionalidad.
