Assessing the potential for reopening a building stone quarry : Newbigging Sandstone Quarry, Fife
Newbigging Sandstone Quarry in Fife is one of a number of former quarries in the Burntisland-
Aberdour district which exploited the pale-coloured Grange Sandstone from Lower
Carboniferous rocks. The quarry supplied building stone from the late 19th century, working
intermittently from 1914 until closure in 1937, and again when reopened in the 1970s to the
1990s. The stone was primarily used locally and to supply the nearby markets in the Scottish
Central Belt.
Historical evidence indicates that prior to sandstone extraction, the area was dominated by largescale
quarrying and mining of limestone, and substantial sandstone quarrying is likely to have
begun after the arrival of the main railway line in 1890. It is probable that removal of the
sandstone was directly associated with limestone exploitation, and that the quarried sandstone
was effectively a by-product of limestone production. Sandstone extraction was probably viable
due to the existing limestone quarry infrastructure (workforce, equipment, transportation) and the
high demand for building stone in Central Scotland in the late 19th century.
The geology within Newbigging Sandstone Quarry is dominated by thick-bedded uniform
sandstone with a wide joint spacing, well-suited for obtaining large blocks. However, a
mudstone (shale) band is likely to be present within a few metres of the principal (north) face of
the quarry, around which the sandstone bed thickness and quality is likely to decrease. The
mudstone bed forms a plane sloping at a shallow angle to the north, so that expansion of the
quarry in this direction is likely to encounter a considerable volume of poor quality stone.
Additionally, an east-west trending fault is present approximately 100 metres north of the quarry
face, which is also likely to be associated with poor quality (fractured) stone
Influence of Teaching Style on Physical Education Adolescents’ Motivation and Health-Related Lifestyle
According to various WHO reports in 2018, a large number of adolescents worldwide are either overweight or obese. This situation is the result of not following a healthy and balanced diet, combined with a lack of practice of physical activity. In this sense, Physical Education classes could help to solve the problem. The present study seeks to analyze the relationship between the role of the teacher in relation to the structural dimensions of the PE teaching environment and the basic psychological needs and self-motivation of adolescents as determinants of their behaviors related to eating habits and the practice of physical activity. A total of 1127 secondary school adolescents between the ages of 13 and 18 participated in this study. Questionnaires were used: Perceived Autonomy Support Scale, Psychologically Controlling Teaching Scale, Basic Psychological Needs in Physical Education, Frustration of Psychological Needs in PE context, Physical Activity Class Satisfaction Questionnaire, Perceived Locus of Causality Revised, and WHO’s Global school-based student health survey. A structural equations model was elaborated to explain the causal relationships between the variables. The results showed that autonomy support positively predicted the three structural dimensions of PE classes, while, in contrast, they were negatively predicted by psychological control. The three structural dimensions positively predicted the satisfaction of psychological needs and negatively predicted the thwarting of psychological needs. Self-determined motivation was positively predicted by the satisfaction of psychological needs and negatively predicted by the thwarting of psychological needs. Finally, self-determined motivation positively predicted healthy eating habits and the practice of physical activity and negatively predicted unhealthy eating habits. Certainly, the results obtained in this study support the postulates of the self-determination theory, demonstrating the predictability of PE class context towards the adoption of healthy lifestyle habits, such as a proper diet and the regular practice of physical activity

Validation of the Satisfaction Scale of Basic Psychological Needs in Physical Education with the Incorporation of the Novelty in the Spanish Context
The purpose of the study was to validate to the physical education context, the Spanish version of the Scale of the Satisfaction of Psychological Needs toward the Physical Education classes of Menéndez and Fernández-Rio, with the incorporation of the novelty, since they contemplated its inclusion. In this study, 1444 students participated (mean = 15.34, standard deviation = 1.12) from several schools in Almeria. To analyze the psychometric properties of the scale, several analyses were carried out. The results offered support for both the four-factor structure and the higher-order model called satisfaction. The analysis of invariance with respect to gender showed that the factor structure of the questionnaire was invariant. The Cronbach alpha values were higher than 0.70 in the subscales. The results of this study demonstrated the reliability and validity of the Scale of the Satisfaction of Psychological Needs, with the incorporation of novelty in the Spanish context of Physical Education
Physical Education Classes as a Precursor to the Mediterranean Diet and the Practice of Physical Activity
Physical activity and a healthy, balanced diet are remaining unresolved issues among young people. According to the World Health Organization, young people do not get enough exercise during the week, and physical education classes are the best way to promote healthy habits. This study aims to analyze how the role of the teacher influences the frustration of psychological needs, coping strategies, motivation, and the adoption of healthy eating habits through the Mediterranean diet and the regular practice of physical activity. The study involved 1031 boys and 910 girls between the ages of 13 and 18. To explain the relationships between the different variables included in this study, a model of structural equations has been developed. The results showed that autonomy support negatively predicted the frustration of four psychological needs. The failure to meet four psychological needs negatively predicted resilience. Likewise, resilience positively predicted autonomous motivation, and this positively predicted the Mediterranean diet and the practice of physical activity. Thus, the results obtained in the present study are in line with those of various studies wherein physical education classes were seen to help consolidate healthy living habits
Estudio filogenético de los géneros de Trichopterygini de Sudamérica Austral (Lepidoptera: Geometridae): una nueva clasifi cación
Phylogenetic study of the genera of South American Austral Trichopterygini (Lepidoptera: Geometridae, Larentiinae): a new classifi cation. In this work, we evaluate the taxonomy of the Trichopterygini in Chile based on a phylogenetic analysis of the morphological attributes. In our analysis, we used Tatosoma and Sauris as outgroups. Two approaches were used to evaluate phylogenetic relationships: 1) parsimony criterion, and 2) Bayesian inference. Parsimony analysis was conducted in PAUP software, and Bayesian analysis with Markov chain Monte Carlo using the BayesPhylogenies software. Our results based on the phylogenetic hypothesis suggest a new taxonomic order for Trichopterygini of the Andean Region of Southern South America. The valid genera are: Arrayanaria Parra, Butleriana Parra, Danielaparra Kemal & Kocak, Fueguina Parra, Hoplosauris Butler, Lagynopteryx Berg, Llampidken Parra & Santos-Salas, Pachrophylla Blanchard, Parapachrophylla Parra, Rindgenaria Parra, Tomopteryx Philippi, Triptila Warren, Triptiloides Parra & Santos-Salas, Warrenaria Parra. The main changes with respect to the previous taxonomic order are: 1) the genus Lagynopteryx Berg is subordinated under the Trichopterygini; 2) Toxopaltes Warren is a junior synonym of Lagynopteryx; 3) Hoplosauris moesta is transferred to the genus Llampidken; 4) Llampidken valdiviana is a junior synonym of L. moesta; 5) Oparabia arenosa is newly combined with the genus Arrayanaria; 6) Danielaparra viridis is a junior synonym of D. fragmentata; 7) Lobophoraimbricaria is newly combined with the genus Danielaparra; 8) Triptiloides fasciata is a junior synonym of T. randallae; and 9) Parapachrophylla michelleae Parra n. sp. is described. Andean Region species are more closely related to the genus Tatosoma from New Zealand, the synapomorphies that demonstrate this are: swollen metaepimeron and hypertrophy of the second abdominal segment. A checklist of the genera and species of the tribe in the region, and the fi gures of adults and genitalia of some species are included.En este trabajo se evalúa la taxonomía de los Trichopterygini de Chile a partir de un análisis fi logenético de los atributos morfológicos. En nuestro análisis, hemos utilizado Tatosoma y Sauris como grupos externos. Se utilizaron dos enfoques para evaluar las relaciones fi logenéticas: 1) criterio de parsimonia, y 2) inferencia bayesiana. El análisis de parsimonia se realizó a través del programa PAUP y el análisis bayesiano con cadenas de Markov y Monte Carlo a través del programa BayesPhylogenies. Nuestros resultados basados en la hipótesis fi logenética sugieren un nuevo orden taxonómico para Trichopterygini de la Región Andina del Sur de Sudamérica. Los géneros válidos son: Arrayanaria Parra, Butleriana Parra, Danielaparra Kemal & Kocak, Fueguina Parra, Hoplosauris Butler, Lagynopteryx Berg, Llampidken Parra & Santos-Salas, Pachrophylla Blanchard, Parapachrophylla Parra, Rindgenaria Parra & Santos-Salas, Tomopteryx Philippi,Triptila Warren y Warrenaria Parra. Los principales cambios con respecto al orden taxonómico anterior son: 1) el género Lagynopteryx Berg se incorpora a Trichopterygini; 2) Toxopaltes Warren es el sinónimo junior de Lagynopteryx; 3) Hoplosauris moesta se incorpora al género Llampidken; 4) Llampidken valdiviana es el sinónimo junior de L. Moesta; 5) Oparabia arenosa es incorporada al género Arrayanaria; 6) Danielaparra viridis es el sinónimo junior de D. fragmentata; 7) Lobophora imbricaria es incorporada al género Danielaparra; Triptiloides fasciata es el sinónimo junior de T. randallae; y 9) Parapachrophylla michelleae Parra n. sp. es descrita. Las especies de la Región Andina están más cerca del Tatosoma de Nueva Zelanda, las sinapomorfi as que demuestran esto son: el metaepimeron hinchado y la hipertrofia del segundo segmento abdominal. Se incluye un catálogo de los géneros y especies de la tribu en la región, y fotografías de adultos y armaduras genitales de algunas especies
Late vacuum choice and slow roll approximation in gravitational particle production during reheating
In the transition between inflation and reheating, the curvature scalar
typically undergoes oscillations which have significant impact on the density
of gravitationally produced particles. The commonly used adiabatic vacuum
prescription for the extraction of produced particle spectra becomes a
non-reliable definition of vacuum in the regimes for which this oscillatory
behavior is important. In this work, we study particle production for a scalar
field non-minimally coupled to gravity, taking into account the complete
dynamics of spacetime during inflation and reheating. We derive an
approximation for the solution to the mode equation during the slow-roll of the
inflaton and analyze the importance of Ricci scalar oscillations in the
resulting spectra. Additionally, we propose a prescription for the vacuum that
allows to safely extrapolate the result to the present, given that the test
field interacts only gravitationally. Lastly, we calculate the abundance of
dark matter this mechanism yields and compare it to observations.Comment: 24 pages, 11 figure
Working with the HL7 metamodel in a Model Driven Engineering context
HL7 (Health Level 7) International is an organization that defines health information standards. Most HL7
domain information models have been designed according to a proprietary graphic language whose
domain models are based on the HL7 metamodel. Many researchers have considered using HL7 in the
MDE (Model-Driven Engineering) context. A limitation has been identified: all MDE tools support UML
(Unified Modeling Language), which is a standard model language, but most do not support the HL7 proprietary
model language. We want to support software engineers without HL7 experience, thus realworld
problems would be modeled by them by defining system requirements in UML that are compliant
with HL7 domain models transparently. The objective of the present research is to connect HL7 with software
analysis using a generic model-based approach. This paper introduces a first approach to an HL7
MDE solution that considers the MIF (Model Interchange Format) metamodel proposed by HL7 by making
use of a plug-in developed in the EA (Enterprise Architect) tool.Ministerio de Ciencia e Innovación TIN2013-46928-C3-3-RInstituto de Salud Carlos III PI12/01571Instituto de Salud Carlos III PT13/0006/003
