Análisis de la técnica de laboreo en bandas (Strip Till) en ensayos de campo reales

Resumen: Estudio de la técnica agrícola que es novedosa en España, mediante la realización de dos ensayos en los que se pueda constatar el comportamiento de la técnica en condiciones reales, en una finca representativa en condiciones de regadío en el término municipal de Sariñena. En el primero se compara el trabajo de un apero Strip-Till con una pasada y dos pasadas antes de la siembra. En el segundo ensayo, en maíz de doble cosecha después de cebada y de siembra en julio, se estudia el comportamiento de este apero en este tipo de condiciones, así como realizar una comparación distribuyendo abono localizado y abono en superficie.Palabras clave: línea, mínimo laboreo,  apero

Análisis de la técnica de laboreo en bandas (Strip Till) aplicada a cultivos en línea (Zea mays) en el término municipal de Sariñena (Huesca)

Se ha estudiado la adaptación de una nueva técnica de trabajo de suelo para cultivos en línea, comprobando tanto la adaptación de la técnica al medio (cultivo, suelo, clima, época del año, etc) como la adaptación de la técnica al marco económico que acoge estos cultivos en línea. Para ello se ha evaluado, entre otros parámetros, el rendimiento en el campo y los consumos y gastos que influyen a este novedoso trabajo del suelo. Para su análisis se llevaron a cabo dos ensayos en dos parcelas contiguas en el término municipal de Sariñena. En el primer ensayo, se evaluó la sistemática del laboreo en bandas previa a la siembra del maíz, que se efectuó en el mes de abril así como el comportamiento de este cultivo y su adaptación a ese nuevo medio. En el segundo ensayo, se comprobó el comportamiento de esta técnica en la problemática de la doble cosecha, es decir, con el poco espacio temporal que existió entre la cosecha de un cereal de invierno (cebada) y la siembra de un maíz de ciclo corto en el mes de julio. También se estudió la evolución de este cultivo durante su implantación y crecimiento así como se evaluó la rentabilidad de esta técnica, viendo que a priori, si la comparábamos con un laboreo convencional, podían disminuir los costes y consumos, debido a que con esta técnica no se trabajó el suelo en la totalidad de la superficie, solo fueron necesarias una y dos pasadas con este apero de laboreo en bandas e incluso en la misma pasada que se realizó el laboreo en bandas se incorporó el abono al suelo, por lo tanto, resultó interesante estudiar el coste de maquinaria y de mano de obra, así como en tiempo o en combustible

Critical pathway for deceased tissue donation: a novel adaptative European systematic approach

Vía crítica; Donantes de tejidos; Obtención de tejidoCritical pathway; Tissue donors; Tissue procurementVia crítica; Donants de teixits; Obtenció de teixitsA ‘Critical pathway for deceased tissue donation’ was developed by the European Committee on Organ Transplantation of the Council of Europe (CD-P-TO) with the aim of providing a common systematic approach to the deceased tissue donation process. Definitions of tissue donors according to the donation stage have been developed so that they can be adapted to different local scenarios. This critical pathway can be used retrospectively to evaluate the potential of tissue donation, assess performance in the tissue donation process and identify areas for improvement. It sets the basis to build indicators to compare organizations, regions and countries. The critical pathway can also be used prospectively to promote good practices in tissue donation programmes aimed at covering the tissue transplantation needs of patients

Enredando Personas, Tejiendo Comunidad

“Getting people involved, knitting up a Community” is a project aiming at creating a volunteering network in the town of Borja (Zaragoza). It consists in a group of volunteers to carry out leisure time activities with elderly people in both residences in the municipality, all of it taking advantage of the current social network already made up by the neighbourhood.The starting point of the project is to plan a schedule of activities, from September 2020 until June 2021, in the two residences, to be accomplished by different associations, institutions and schools.The main proposal is to develop within the neighbourhood a feeling of belonging to a community, usefulness, personal growth and the acquisition of roles of commitment and responsibility. This project is to be included in the Master on Leadership and Management of Social Services of the University of Zaragoza. This master starts with an introduction where the development, motivations, objectives and main hypotheses of the project are explained. Next, the methodology of the investigation is clarified. The conceptual and legal framework include topics such as volunteering and unwanted loneliness among elderly people, whereas the analysis of the context shows an increasingly ageing society, as much as an analysis of institutions and volunteering projects. It also includes a reference to the influence of the coronavirus pandemic in the residential field. After that, the results of the research are detailed and the TFM proposal is developed. This proposal includes a definition, objectives, schedule, resources, funding, communication, training and evaluation, together with the point of view of social responsibility. Finally, the main drawbacks and final conclusions are reflected.<br /

Improving Functionalities in a Multi-agent Architecture for Ocean Monitoring

This paper presents an improved version of a multiagent architecture aimed at providing solutions for monitoring the interaction between the atmosphere and the ocean. The ocean surface and the atmosphere exchange carbon dioxide. This process is can be modeled by a multiagent system with advanced learning and adaption capabilities. The proposed multiagent architecture incorporates CBR-agents. The CBR-agents proposed in this paper integrate novel strategies that both monitor the parameters that affect the interaction, and facilitate the creation of models. The system was tested and this paper presents the results obtained

Uncontrolled Donation after Circulatory Death: European practices and recommendations for the development and optimization of an effective programme.

Shortage of organs has made a global interest for donation after circulatory death (DCD) to re-emerge. While controlled DCD (cDCD) has been progressively increasing, uncontrolled DCD (uDCD) has only been developed in a few settings.1 This activity is quantitatively important in France and Spain, although it has also been reported in other European countries, as Austria, Belgium, Italy, the Netherlands, and recently in Russia.2,3 uDCD protocols have allowed the transplantation of a significant number of kidneys, livers and lungs at these countries.3 Excellent graft survival has been reported in kidney transplantation from uDCD, in spite of an increased incidence of delayed graft function (DGF).4,5,6,7,8,9,10,11,12,13,14,1516 Albeit promising, results with liver transplants obtained in uDCD protocols do not consistently provide similar outcomes compared with livers from donors after brain death (DBD), mainly due to a higher incidence of primary graft dysfunction and non-function and biliary complications.17,18,19,20,21,22 Lung transplantation is still facing limited experience, but preliminary results are encouraging.pre-print938 K

Angiotensin II type 2 receptor as a novel activator of brown adipose tissue in obesity

The angiotensin II type 2 receptor (AT2R) exerts vasorelaxant, anti-inflammatory, and antioxidant properties. In obesity, its activation counterbalances the adverse cardiovascular effects of angiotensin II mediated by the AT1R. Preliminary results indicate that it also promotes brown adipocyte differentiation in vitro. Our hypothesis is that AT2R activation could increase BAT mass and activity in obesity. Five-week-old male C57BL/6J mice were fed a standard or a high-fat (HF) diet for 6 weeks. Half of the animals were treated with compound 21 (C21), a selective AT2R agonist, (1 mg/kg/day) in the drinking water. Electron transport chain (ETC), oxidative phosphorylation, and UCP1 proteins were measured in the interscapular BAT (iBAT) and thoracic perivascular adipose tissue (tPVAT) as well as inflammatory and oxidative parameters. Differentiation and oxygen consumption rate (OCR) in the presence of C21 was tested in brown preadipocytes. In vitro, C21-differentiated brown adipocytes showed an AT2R-dependent increase of differentiation markers (Ucp1, Cidea, Pparg) and increased basal and H+ leak-linked OCR. In vivo, HF-C21 mice showed increased iBAT mass compared to HF animals. Both their iBAT and tPVAT showed higher protein levels of the ETC protein complexes and UCP1, together with a reduction of inflammatory and oxidative markers. The activation of the AT2R increases BAT mass, mitochondrial activity, and reduces markers of tissue inflammation and oxidative stress in obesity. Therefore, insulin reduction and better vascular responses are achieved. Thus, the activation of the protective arm of the renin–angiotensin system arises as a promising tool in the treatment of obesity15 página

Renal transplantation in patients with hepatitis C virus antibody. A long national experience

Background. Renal transplantation is the best therapy for patients with hepatitis C virus (HCV) infection with end-stage renal disease. Patient and graft survival are lower in the long term compared with HCV-negative patients. The current study evaluated the results of renal transplantation in Spain in a long period (1990–2002), focusing on graft failure

The economic impact of machine perfusion technology in liver transplantation

Introduction: Several clinical studies have demonstrated the safety, feasibility, and efficacy of machine perfusion in liver transplantation, although its economic outcomes are still underexplored. This review aimed to examine the costs related to machine perfusion and its associated outcomes.Methods: Expert opinion of several groups representing different machine perfusion modalities. Critical analysis of the published literature reporting the economic outcomes of the most used techniques of machine perfusion in liver transplantation (normothermic and hypothermic ex situ machine perfusion and in situ normothermic regional perfusion).Results: Machine perfusion costs include disposable components of the perfusion device, perfusate components, personnel and facility fees, and depreciation of the perfusion device or device lease fee. The limited current literature suggests that although this upfront cost varies between perfusion modalities, its use is highly likely to be cost-effective. Optimization of the donor liver utilization rate, local conditions of transplant programs (long waiting list times and higher MELD scores), a decreased rate of complications, changes in logistics, and length of hospital stay are potential cost savings points that must highlight the expected benefits of this intervention. An additional unaccounted factor is that machine perfusion optimizing donor organ utilization allows patients to be transplanted earlier, avoiding clinical deterioration while on the waiting list and the costs associated with hospital admissions and other required procedures.Conclusion: So far, the clinical benefits have guided machine perfusion implementation in liver transplantation. Albeit there is data suggesting the economic benefit of the technique, further investigation of its costs to healthcare systems and society and associated outcomes is needed.</p
