HOMEMADE SLOW-ACTION FERTILIZERS, AS AN ECONOMIC SOLUTION FOR ORGANIC FOOD PRODUCTION
2017
Organic plant cultivation, especially those intended for human consumption, poses new requirements for gardening. It is recommended to use organic slow-action fertilizers, which provide doses of nutrients essential for plants for a long time. Particularly valuable fertilizers are those that arise within the household, due to their high quality and the absence of costs associated with their purchase and transport. Organic matter contained in the food industry waste or arising in households, in the absence of contamination by other types of waste, can be used for self-production of organic fertilizer. The paper presents the results of testing organic fertilizers, which you can make yourself, …
How critical thinking should be at the heart of digital interactions?
2018
In this paper, we explore how to teach critical thinking in the digital age, in order to promote the autonomy of practitioners. An interaction theory is proposed to identify the constraints that structure digital creativity. This model helps to design a critical pedagogy, linking without opposing a procedural approach to a reflective approach. The article presents an implementation of this model in a writing course on a social network. The study of students' activity logs shows the presence of forms of objectivity and reflexivity, reflecting the development of critical thinking. This approach offers a way to develop critical thinking not from the outside, in an argumentation or media analys…
Conductas de riesgo y actitudes relacionadas con la infección por vih/sida en hsh
2014
Abstract:The aim of this investigation is to analyze sexual risk behaviors and attitudes for HIV/AIDS infection of MSM. The ENSI was administrated to 202 men, 168 homosexuals and 24 bisexuals, from 14 to 57 years. The results show a high confidence in condoms as a method of HIV prevention (75.7% very effective and 28.1% effective); however the systematic use of a condom is moderate in anal intercourse (54.64%) and in vaginal intercourse (49.05%) and very low in oral sex (6.22%). There is a low perceived probability (20.28%) and moderate fear (41.25%) become infected with HIV. 20.3% report having drunk alcohol in the last relationship and 5.4% say other drugs. These results should be conside…
Protective coloration of European vipers throughout the predation sequence
2020
Antipredator adaptations in the form of animal coloration are common and often multifunctional. European vipers (genus Vipera) have a characteristic dorsal zigzag pattern, which has been shown to serve as a warning signal to potential predators. At the same time, it has been suggested to decrease detection risk, and to cause a motion dazzle or flicker-fusion effect during movement. We tested these hypotheses by asking whether (1) the zigzag pattern decreases detection risk and (2) the detection is dependent on the base coloration (grey or brown) or the snake's posture (coiled, basking form or S-shaped, active form). Additionally, (3) we measured the fleeing speed of adders, Vipera berus, an…
El error diagnóstico en radiología. Análisis de variables explicativas
2019
ANTECEDENTES: Se ha demostrado que la etiología del error médico es multifactorial, con convergencia de factores humanos activos (errores de percepción, cognición y/o comunicación) y factores latentes del sistema. Los factores latentes del sistema son aquellas variables que pueden predisponer a la aparición de errores activos, o aumentar el impacto negativo de estos. Incluyen una amplia variedad de elementos, entre otros el material de trabajo inadecuado, la sobrecarga de trabajo, la falta de experiencia del radiólogo, la información clínica insuficiente y la no disponibilidad de estudios previos. Nuestra hipótesis de trabajo es que los factores latentes contribuyen significativamente al er…
Interactive Effects of Genotype and Molybdenum Supply on Yield and Overall Fruit Quality of Tomato
2019
Molybdenum (Mo) is an essential trace element for plant growth, development, and production. However, there is little known about the function and effects of molybdenum in tomato plants. The present study assessed the influences of different Mo concentrations on four tomato F1 hybrids (“Bybal” F1, “Tyty” F1, “Paride” F1, and “Ornela” F1) grown using a soilless system with different Mo levels [0.0, 0.5 (standard NS), 2.0, and 4.0 μmol L−1, respectively]. The crop yield, plant vigor, fruit skin color, TA, fruit water content as well as the accumulation of SSC, and some antioxidant compounds such as lycopene, polyphenols and ascorbic acid were evaluated. The minerals concentration, including n…
Trabajo y TIC en los mayores de 45 años. Un análisis de la introducción al ciberespacio desde la esfera laboral
2018
The inequality in access to cyberspace due to age at the beginning of the twenty-first century was followed by an economic crisis that intensified many socio-labor dynamics. Through a contextualization with INE data and a qualitative sample, the following work tries to capture the attitudes about ICT related to their previous labor trajectories on those over 45 years of age; and, on the other hand, its introduction to cyberspace from work as a conditioner in the perception of crisis, the maintenance of employment or their way out to retirement.
Time and heat for sexual reproduction: comparing the phenology of Chara hispida of two populations at different latitudes
2017
Abstract Geographical location affects the main ecological factors driving the timing of plants’ life events. In addition, studying phenology is the simplest procedure to track current global warming and its effects on the success and survival of different populations of the same species. Little is known about the effect of water temperature and its corresponding accumulated heat on charophytes’ phenology. We compared differences in water temperature and sexual reproductive phenology of Chara hispida in two ponds of two countries located at different latitudes (Spain and Switzerland) over the same year. We estimated the accumulated heat required to develop from one phenophase to another (un…

Combined dynamics of the 500–600 nm leaf absorption and chlorophyll fluorescence changes in vivo: Evidence for the multifunctional energy quenching r…
2021
Carotenoids (Cars) regulate the energy flow towards the reaction centres in a versatile way whereby the switch between energy harvesting and dissipation is strongly modulated by the operation of the xanthophyll cycles. However, the cascade of molecular mechanisms during the change from light harvesting to energy dissipation remains spectrally poorly understood. By characterizing the in vivo absorbance changes (Delta A) of leaves from four species in the 500-600 nm range through a Gaussian decomposition, while measuring passively simultaneous Chla fluorescence (F) changes, we present a direct observation of the quick antenna adjustments during a 3-min dark-to-high-light induction.
