Increasing the security and traceability of biological samples in biobanks by blockchain technology
(Elsevier, 2023-04) Ortiz Lizcano, María Isabel; Arias Antúnez, Enrique; Hernández Bravo, Ángel; Caminero Herráez, Maria Blanca; Rojo Guillen, Tomás; Nam-Cha, Syong Hyun
One of the main tasks in a biobank consists in storing biological samples in a high-quality condition in order to future research. At moment, there exist many applications to manage a biobank. However, in general, these are web-based applications. In these web-based applications different tasks can be done. Among them, it is possible to remark the following: informed consent, confidentiality, non-profit, respect for quality and safety standards, including traceability of samples. In this paper, we describe a blockchain smart contract to ensure the traceability of the processes done in a biobank meaning a step forward to guarantee this traceability.
An intelligent irrigation management model for direct injection of solar pumping systems
(Elsevier, 2023-01-31) Cervera Gascó, Jorge; Montero Martínez, Jesús; Moreno Hidalgo, Miguel Ángel
The photovoltaic pumping systems are useful for irrigation, but must ensure that water is applied to the crop as uniformly and efficiently as possible at all points of the irrigation subunit. To solve this problem, the I-Selector model was developed. It allowed to generate irrigation schedules with the application of quality criteria both for combinations of subunits studied individually (with a standard deviation in the applied water sheet: 2.8 m3·ha−1) and for combinations of several subunits studied working together depending on,among other things, the available photovoltaic energy and the extraction capacity of the well, allowing to compare and analyze the best irrigation strategy to be used and being a flexible model that can be used in any case of study. Thus, the I-Selector model has generated irrigation schedules to establish the optimal sequence of opening combinations of subunits distributed by daily time slots, thus indicating the convenience of its use at each time of day for the best use of water and energy in a high-power solar pumping system located in Albacete, Spain.
Towards a circular economy for Pt catalysts. Case study
(Elsevier, 2023-01-24) Montiel, Miguel A.; Granados Fernández, Rafael; Diaz Abad, Sergio; Saez, C.; Fernández Marchante, Carmen María; Rodrigo, Manuel Andrés; Lobato Bajo, Justo
This work links two challenges that our society is facing nowadays, the climate change and the scarcity of key raw materials as the platinum group materials are. Hence, Pt from membrane electrode assemblies used in the well-known Westinghouse cycle for hydrogen production has been successfully recovered using the selective electrochemical dissolution process and reaching global efficiencies of 70 wt%. Pt electrocatalysts were synthesized from the Pt recovered from the spent electrodes and characterized. Thus, the scanning electrochemical microscopy technique demonstrated that Pt was well dispersed onto the carbon support. Moreover, electrodes with both, commercial and recovered Pt/C catalysts were prepared and tested. The electrodes with the catalyst prepared from the spent MEAs show a good activity towards the SO2 oxidation, the reaction for H2 production, and above all, a very high stability. In conclusion, the circular economy of Pt based catalyst for a H2 production process has been achieved.

Compassion in Hotels: Does Person–Organization Fit Lead Staff to Engage in Compassion-Driven Citizenship Behavior?
(Sage Journals, 2023) Zoghbi Manrique de Lara, Pablo; Ruiz Palomino, Pablo; Linuesa Langreo, Jorge
Existing research on person–organization (P-O) fit (POF) has ignored other-centered mechanisms in explaining why high levels of fit with the work environment increase employee’s organizational citizenship behavior (OCB). Using four factors involved in the compassion process (common humanity, empathic concern, kindness, mindfulness), this article investigates employee compassion as a mediator that explains why POF affects OCB directed toward individuals (OCBI) and the organization (OCBO). Our structural equation modeling analysis on 280 Spanish hotel employees reveals that compassion mediates the relationship between POF and OCBs. However, considering the employment contract of the sample (temporary, permanent), the mediation for OCBO was partial and full among permanent and temporary staff, respectively. These findings suggest that staff who fit their hotel are more likely to be sensitive to others’ setbacks and misfortunes, lessening or alleviating them (compassionately) by performing OCBs. However, compared with permanent staff, temporary staff’s OCBO response to POF is more compassion-driven.
