The Study of Growth and Performance in Local Chicken Breeds and Varieties: A Review of Methods and Scientific Transference

A review of the scientific advances in the study of the growth and performance in native chicken breeds and varieties over the past 20 years was performed. Understanding the growth patterns of native breeds can only be achieved if the constraints characterizing these populations are considered and treated accordingly. Contextually, the determination of researchers to use the same research methods and study designs applied in international commercial poultry populations conditions the accuracy of the model, variability capturing ability, and the observational or predictive performance when the data of the local population are fitted. Highly skewed sex ratios favouring females, an inappropriate census imbalance compensation and a lack of population structure render models that are regularly deemed effective as invalid to issue solid and sound conclusions. The wider the breed diversity is in a country, the higher the scientific attention paid to these populations. A detailed discussion of the most appropriate models and underlying reasons for their suitability and the reasons preventing the use of others in these populations is provided. Furthermore, the factors conditioning the scientific reception and impact of related publications used to transfer these results to the broad scientific public were evaluated to serve as guidance for the maximization of the success and dissemination of local breed information

Assessment of the Evolution of a Landslide Using Digital Photogrammetry and LiDAR Techniques in the Alpujarras Region (Granada, Southeastern Spain)

In this work a detailed analysis of the temporal evolution of the Almegíjar landslide is presented. It is a rock slide located in the Alpujarras region (Granada, Spain) that has developed over the last 30 years. Six datasets and photogrammetric flights corresponding to the years 1956, 1984, 1992, 2001, 2008, and 2010 were surveyed. The more recent flight of 2010 combined an aerial digital camera and a LiDAR sensor and was oriented by means of in-flight data and tie points. This 2010 flight allowed for the generation of a reliable and high-precision Digital Terrain Model (DTM). The other flights were oriented using second-order ground control points transferred from the 2010 flight, and the corresponding DTMs were prepared by automatic matching and subsequent editing from the stereoscopic models. After comparing the DTMs of different dates, it has been observed that the landslide was triggered after 1984 and since then has evolved in an irregular pattern with periods of variable activity. On average, the ground surface dropped more than 8 m in depleted zones and rose nearly 4 m in the accumulation zones, with a velocity catalogued as very slow (about 15–30 cm/year) over a time span corresponding to a degree VIII of diachroneity. The total volume of the mobilized mass of this large contemporary slide was about 300 × 103 m3.This research was funded by the projects P06-RNM-02125 and RNM-06862 (ISTEGEO) funded by the Andalusian Research Plan, projects CGL2008-04854 and TIN2009-09939 funded by the Ministry of Science and Innovation of Spain and Research Groups TEP-213, and RNM 221 of the Andalusian Research Plan

Smart Solar Micro-exchangers for Sustainable Mobility of University Camps

Publicado el resumen en: https://www.wmcaus.org/files/WMCAUS2020_Book.pdf. Pendiente de publicación de las contribuciones en IOP Conference Series: Materials Science and Engineering.A significant number of universities have several campuses located in urban or rural settings, or with scattered university buildings that require the use of means of transportation. This implies the mobility and potential displacement of a large community of students, professors and researchers. The use of electric bicycles (e-bikes) is an intermediate alternative between the bicycle and electric cars. It can be an important stimulus for the promotion of the decarbonisation of the University Campus, avoiding the traffic congestion and reducing space requirements for parking. This paper presents the smart solar micro-exchanger model managed through a sustainable mobility web platform, applied to the case study of the University of Malaga (Spain). It is a solar charging station for e-bike, whose design is based on the principles of solar architecture (providing great security to e-bike). It managed by a web platform and app that allows the user to make reservations and learn about the savings in CO2 emissions. The system allows performing an aerobic sports activity without sweating problems when you reach the job. The platform also incorporates a database of quiet and safe routes for e-bike users.Universidad de Málaga. Campus de Excelencia Internacional Andalucía Tec

Attitudes toward the physical activity and sport practice in Spanish adolescents: the AVENA study

El objetivo del estudio se centra en conocer las actitudes hacia la práctica de actividad físico deportiva orientada a la salud en una muestra representativa de adolescentes españoles. Para ello, se ha efectuado un estudio descriptivo de corte transversal, empleando la encuesta sobre comportamientos, actitudes y valores sobre actividad física y deportiva del Grupo AVENA. El análisis descriptivo e inferencial, nos permite obtener la opinión de 2.859 estudiantes, procedentes tanto de centros públicos como privados de cinco ciudades españolas: Granada, Madrid, Murcia, Santander y Zaragoza. Los principales resultados verifican que tanto chicos como chicas presentan una mayor orientación hacia actitudes relacionadas con el proceso (AP) de la actividad físico-deportiva que hacia actitudes referidas al resultado (AR) de dicha práctica. En ambos sexos, se produce una disminución progresiva en dicha orientación, tanto en las AP como en las AR, conforme aumenta la edad. En aquellos adolescentes que practican actividad física, la orientación hacia las actitudes es mayor que en adolescentes no practicantes. Como conclusión, las AP adquieren mayor importancia que las AR en los jóvenes adolescentes, siendo ambas mayores en chicos respecto a chicas y disminuyendo los valores de ambas conforme aumenta la edad. El conocimiento facilitado en este trabajo podría servir de apoyo para perfeccionar las diversas estrategias de promoción de la salud sobre las que asentar la adquisición de nuevos estilos de vida entre la población joven de una forma estable y duradera.The aim of this study was to know the attitudes toward the physical activity and sport practice oriented to health in a representative sample of Spanish adolescents. A descriptive cross-sectional study was implemented and the survey about behaviours, attitudes and values related to physical activity and sport practice developed in the AVENA study was used. The sample size was 2859 Spanish students from public and private secondary schools in 5 Spanish cities: Granada, Madrid, Murcia, Santander and Zaragoza. The main results verify that both boys and girls have a greater orientation towards process-related attitudes (PA) of physical activity and sport that outcome-related attitudes (AR) of the practice. In boys and girls, both AP and AR both genders, there is a progressive decrease when increasing the age. Adolescents who engaged in physical activity had higher levels of attitudes than non-practitioners. In conclusion, AP became more important than AR in young adolescents; both AP and AR were higher in boys than in girls and attitude values decreased with increasing age. The knowledge of attitudes might allow to develop effective and long-term successful intervention programmes for adopting healthy lifestyles in the current young peopl

Interventions of different society institutions are required, being particularly relevant educational institutions. The aim of the study is to analyze the interest physical activity and sport regarding the level of participation in this practice and to know the reasons for abandoning and non practicing in a representative sample of Spanish adolescents. A descriptive cross-sectional study was implemented and the survey about behaviours, attitudes and values related to physical activity and sport practice, which was developed in the AVENA (Feeding and assessment of nutritional status of spanish adolescents) study. The sample size was 2859 Spanish adolescents (1.357 men, 1.502 women; age range: 13-18.5 years) and chosen from among students of secondary education, both from public and private schools in five Spanish cities: Granada, Madrid, Murcia, Santander and Zaragoza. The main results show a high level of interest about physical activity and sport practice although almost half of the adolescents show an insufficient level regarding the level that they would like to practice. The demanding school and laziness and reluctante are the main reasons for stop practicing. The reasons for no practicing are lack of time, and much further the laziness, lack of pleasure with the practice and tiredness because of the school or work. Gender and age modify significantly the interest and reasons for abandoning and non practicing physical activity and sports. The knowledge of these reasons could allow to develop effective and long-term successful intervention programmes for adopting healthy lifestyles in young people

CARB-ES-19 Multicenter Study of Carbapenemase-Producing Klebsiella pneumoniae and Escherichia coli From All Spanish Provinces Reveals Interregional Spread of High-Risk Clones Such as ST307/OXA-48 and ST512/KPC-3.

CARB-ES-19 is a comprehensive, multicenter, nationwide study integrating whole-genome sequencing (WGS) in the surveillance of carbapenemase-producing K. pneumoniae (CP-Kpn) and E. coli (CP-Eco) to determine their incidence, geographical distribution, phylogeny, and resistance mechanisms in Spain. Methods: In total, 71 hospitals, representing all 50 Spanish provinces, collected the first 10 isolates per hospital (February to May 2019); CPE isolates were first identified according to EUCAST (meropenem MIC > 0.12 mg/L with immunochromatography, colorimetric tests, carbapenem inactivation, or carbapenem hydrolysis with MALDI-TOF). Prevalence and incidence were calculated according to population denominators. Antibiotic susceptibility testing was performed using the microdilution method (EUCAST). All 403 isolates collected were sequenced for high-resolution single-nucleotide polymorphism (SNP) typing, core genome multilocus sequence typing (cgMLST), and resistome analysis. Results: In total, 377 (93.5%) CP-Kpn and 26 (6.5%) CP-Eco isolates were collected from 62 (87.3%) hospitals in 46 (92%) provinces. CP-Kpn was more prevalent in the blood (5.8%, 50/853) than in the urine (1.4%, 201/14,464). The cumulative incidence for both CP-Kpn and CP-Eco was 0.05 per 100 admitted patients. The main carbapenemase genes identified in CP-Kpn were bla OXA-48 (263/377), bla KPC-3 (62/377), bla VIM-1 (28/377), and bla NDM-1 (12/377). All isolates were susceptible to at least two antibiotics. Interregional dissemination of eight high-risk CP-Kpn clones was detected, mainly ST307/OXA-48 (16.4%), ST11/OXA-48 (16.4%), and ST512-ST258/KPC (13.8%). ST512/KPC and ST15/OXA-48 were the most frequent bacteremia-causative clones. The average number of acquired resistance genes was higher in CP-Kpn (7.9) than in CP-Eco (5.5). Conclusion: This study serves as a first step toward WGS integration in the surveillance of carbapenemase-producing Enterobacterales in Spain. We detected important epidemiological changes, including increased CP-Kpn and CP-Eco prevalence and incidence compared to previous studies, wide interregional dissemination, and increased dissemination of high-risk clones, such as ST307/OXA-48 and ST512/KPC-3
