An analysis of the role of students’ use of non textual modes of scientific knowledge representation in presentations of vocational training students

Describimos una experiencia de investigación-acción en la que analizamos cómo estudiantes de formación profesional incorporan modos no textuales de representación del conocimiento científico en presentaciones que elaboran para ser expuestas ante sus compañeros. Estudiamos en esos modos no textuales de qué tipo son, su integración y su capacidad de resumir información y, al hallar aspectos a mejorar, profundizamos en ello mediante un estudio de caso. Encontramos que el uso de modos no textuales de representación de conocimiento contribuye a conseguir progresos relevantes en relación con la alfabetización científica en términos comunicativos referentes a expresar y compartir conocimientos.Here is described an action research experience in which we study how the participant vocational training students use non textual modes of scientific knowledge representation in the presentations that they elaborate in order to be exposed to their classmates. We study in those non textual modes their type, integration and power of summarize information, and, as we found aspects to improve, we deepen through a case study. We conclude that the use of non textual modes of scientific knowledge representation can allow relevant progresses related to scientific literacy in communicative terms referred to expressing and sharing knowledge

Bernardo Cienfuegos y su aportación a la Botánica en el siglo XVII

The 17th century represented a parenthesis in Spain's scientific development at an institutional level although learning was preserved and transmitted to the incoming generations by means of individual personalities. Bernardo de Cienfuegos, a physician and botanist, wrote his works in the first half of the 17th century. These amount to seven hand-written bound volumes that are kept at the Spanish National Library and contain some 1,000 drawings of plants, most of them in colour. They actually are a monumental work of recopilation that gather a great number of original data about plants and their application, especially in the realm of medicine.El siglo XVII fue un paréntesis en el desarrollo científico en España a nivel institucional, pero el saber se transmitió a través de personajes aislados. Bernardo de Cienfuegos, médico y botánico, escribió su obra en la primera mitad del siglo XVII. Esta consta de siete tomos manuscritos encuadernados, que se encuentran en la Biblioteca Nacional. Contiene unos 1.000 dibujos de plantas, la mayoría de ellos a color. Se trata de una obra monumental de recopilación y con gran cantidad de datos propios sobre las plantas y sus usos, sobre todo en medicina

Mechanical canopy and trunk shaking for the harvesting mechanization of table olive orchards

Table olive harvesting is highly dependent on manual labour and may jeopardize the crop benefit. The introduction of a mechanical harvest system requires a global evaluation of the whole process. A trunk shaker along with shaker combs and a continuous canopy shaker harvester have been tested in two orchards with different tree training and layout to determine their feasibility to mechanical harvesting in table olives. For that purpose, several parameters have been evaluated. Canopy shaker required adapted orchard layout and hedge of canopies for reaching an acceptable harvesting efficiency about 80% and trunk shaker performed a higher efficiency of more than 95% but depended highly on labour. Both systems had a high field capacity about 0.15 ha h-1 but low for the trunk shaker considering the people (0.01 ha h-1 person-1). The vibration pattern that applied on branches was totally different although the quantitative tree damages were no significative different. There were no significant differences in fruit bruising between both systems, but there were between the different sampling points, mainly in the detachment. The fruit bruising index of the remaining fruit on canopy suggests that it is possible to perform a second harvest. Both mechanical systems are suitable for table olive harvesting whilst improving the efficiency of manual systems with bearable damages, but each one has pros and cons that must be considered bearing in mind that require an adaptation of the orchard where there are applied. Highlights Table olives mechanization is possible by integrating with the fruit liquid store. Trunk shaker performed high efficiency in adapted orchards but depended on labour. Canopy shakers require the adaption of orchard and machine for commercial purposes. There were no differences in detached fruit bruising between both mechanical systems. The bruising index of the remaining fruit on trees suggest second harvesting pass.Table olive harvesting is highly dependent on manual labour and may jeopardize the crop benefit.

The mock up as a learning tool for developing agricultural machinery

Se propone la introducción de un ejercicio basado en proyectos en la asignatura de “Diseño de maquinaria agraria. Automática agraria”. Para resolver el problema los alumnos han de pasar por todas las fases de las metodologías de desarrollo de productos: búsqueda de información, planificación del trabajo, diseño, cálculo, fabricación, etc. Al final, los alumnos deberán obtener una maqueta que modele el trabajo de una máquina agrícola con funciones cargadora o manipuladora. Los alumnos eligieron una metodología de trabajo en grupo por ingeniería secuencial, en lugar de la aconsejada por ingeniería concurrente, dado que requiere menor interacción entre ellos, pero al final del ejercicio expusieron los problemas encontrados habiendo aprendido de los pros y contras de ambas. Los indicadores finales de la práctica muestran la mejora de la calidad docente con mayor participación del alumnado y con mejores resultados académicos. Sin embargo, se requiere del profesorado una dedicación y tiempo extra en la asignatura, así como mayores recursos, por lo que en el futuro se debería intentar la coordinación de la práctica con otras materias similares o con cursos de formación permanente.An exercise based on project is proposed in lesson “Agricultural machinery design. Automation”. To solve the problem, students must go through all phases of product development methodologies: information search, work planning, design, calculation, manufacturing…Finally, they must obtain a model which simulates the work performed by a agricultural machinery with loader or manipulator functions. This year, the students chose a methodology of work sequentially, instead of the one recommended, concurrent engineering. This choice required less interaction among them but at the end they exposed the cons and pros of using it. The teaching indicator show improvement of the quality of the teaching with greater participation of students, and better academic results. However, teachers are required an extra dedication and time, as well as more resources. So, in the future should be coordinated the practice with other similar subjects or extra courses

Coexistence of a fluid responsive state and venous congestion signals in critically ill patients: a multicenter observational proof-of-concept study

Background Current recommendations support guiding fluid resuscitation through the assessment of fluid responsiveness. Recently, the concept of fluid tolerance and the prevention of venous congestion (VC) have emerged as relevant aspects to be considered to avoid potentially deleterious side effects of fluid resuscitation. However, there is paucity of data on the relationship of fluid responsiveness and VC. This study aims to compare the prevalence of venous congestion in fluid responsive and fluid unresponsive critically ill patients after intensive care (ICU) admission. Methods Multicenter, prospective cross-sectional observational study conducted in three medical–surgical ICUs in Chile. Consecutive mechanically ventilated patients that required vasopressors and admitted < 24 h to ICU were included between November 2022 and June 2023. Patients were assessed simultaneously for fluid responsiveness and VC at a single timepoint. Fluid responsiveness status, VC signals such as central venous pressure, estimation of left ventricular filling pressures, lung, and abdominal ultrasound congestion indexes and relevant clinical data were collected. Results Ninety patients were included. Median age was 63 [45–71] years old, and median SOFA score was 9 [7–11]. Thirty-eight percent of the patients were fluid responsive (FR+), while 62% were fluid unresponsive (FR−). The most prevalent diagnosis was sepsis (41%) followed by respiratory failure (22%). The prevalence of at least one VC signal was not significantly different between FR+ and FR− groups (53% vs. 57%, p = 0.69), as well as the proportion of patients with 2 or 3 VC signals (15% vs. 21%, p = 0.4). We found no association between fluid balance, CRT status, or diagnostic group and the presence of VC signals. Conclusions Venous congestion signals were prevalent in both fluid responsive and unresponsive critically ill patients. The presence of venous congestion was not associated with fluid balance or diagnostic group. Further studies should assess the clinical relevance of these results and their potential impact on resuscitation and monitoring practices
