La comunicación de los Objetivos de Desarrollo Sostenible en las organizaciones de la Economía Social
Authors: Herranz de la Casa José María , García Caballero Sara 
Published: March 2021

La agenda 2030 y los Objetivos de Desarrollo Sostenible se han convertido en la referencia que marca la acción de los gobiernos, las naciones, las empresas, las ciudades y los ciudadanos. Cinco años después de su lanzamiento, los datos sobre el cumplimiento de las metas para el año 2030 encuentran áreas críticas y tendencias favorables, lo que hace necesario acelerar el proceso. Las organizaciones de la economía social tienen una oportunidad para posicionarse preferentemente por su filosofía y valores que abarcan la sostenibilidad, la responsabilidad social y la persona. En este artículo se analiza el modelo de comunicación que están desarrollando las principales organizaciones de la economía social en España. Un modelo de comunicación de tres niveles -declarativo, informativo y participativo- que supone un mayor o menor compromiso en la implantación de los ODS dentro de la organización con sus miembros y fuera de ella para visibilizarlos. Se han analizado distintas iniciativas donde la participación de los miembros de organizaciones ha generado reconocimiento en este ámbito. La comunicación no es solo un proceso informativo, sino que supone diálogo y puntos de encuentro para sensibilizar, concienciar y ejercer influencia. Las organizaciones de la economía social no han destacado especialmente por la gestión de la comunicación, pero potenciar la implantación de los ODS puede ser una apuesta firme por diferenciarse en los próximos 10 años.

Authors: Abbasi Milad , Pourrajab Behnaz , Tokhi Mohammad Osman 
Published: March 2021

Abstract

Objectives
Occupational noise-induced hearing loss (NIHL) due to industrial, military, and other job -related noise exposure can cause harmful health issues to occupied workers, but may also be potentially preventable. Vitamins/antioxidant have been studied as therapeutic strategies to prevent and/or delay the risks of human diseases as well as NIHL. So, this study was conducted to systematically review the protective effects of vitamins/antioxidants on occupational NIHL.

Methods
Online databases including PubMed/Medline, Scopus, Web of Science, EMBASE, Science Direct, and Google Scholar were systematically searched up to 12 January 2021. Based on 6336 potentially relevant records identified through the initial search in the databases, 12 full-text publications were retrieved, one of which can be viewed as two separate trials, because it has studied the effects of two different antioxidants (ginseng and NAC) on NIHL, separately.

Results
A review of the studies shows that vitamin B12, folic acid, and N-acetylcysteine (NAC) have a considerable protective effect on NIHL. However, these protective effects are not yet specified in different frequencies. The findings regarding the protective effects of other antioxidants are inconsistent in this field.

Conclusion
Vitamin B12, folic acid, and NAC may have a protective effect as an antioxidant on reducing occupational hearing loss. For a conclusive evidence of vitamin/antioxidant protective therapies, future studies with precise criteria for noise exposure and similar outcome parameters are required.

Published: March 2021

AbstractTetradentate Pt(II) complexes are promising emitters for deep blue organic light‐emitting diodes (OLEDs) due to their emission energy and high photoluminescence efficiency. However, to obtain a pure blue color, spectral red‐shifts, and additional emission peaks at longer wavelengths, originating from strong intermolecular interactions between parallel Pt(II) complexes, must be avoided. Herein, a new class of deep‐blue emitting tetradentate Pt(II) complexes consisting of a non‐planar ligand and a bulky adamantyl group is reported. The six‐membered metallacycle structure renders the Pt(II) complex non‐planar. In addition, the bulky adamantyl groups increase intermolecular distances and decrease red‐shifts in the emission originating from strong dipole–dipole interactions. Therefore, these Pt(II) complexes exhibit little change in emission color with increasing dopant concentration. OLEDs incorporating these new Pt(II) complexes as emitters exhibit deep blue emission with a Commission International de L'Eclairage (CIE) y under 0.13 and a maximum external quantum efficiency of 22.6%, which is one of the highest observed for deep blue (CIE y < 0.15) phosphorescent OLEDs using Pt(II) complexes. These results provide a new approach for designing Pt(II) complexes for high efficiency deep blue OLEDs.

AbstractIn nature, animals or plants often use soft organs to move and hunt. Research works on bioinspired materials and devices have attracted more and more interest as which show the potential for future intelligent robots. As key components of soft robots, biomimetic soft actuators are adapted to greater requirements for convenient, accurate, and programmable controlling robots. Here, a class of materials and processing routes of ultrathin actuators are reported for bioinspired piecewise controllable soft robots, where the actuators associate with thermal‐responsible soft silicone thin film with thickness as thin as 45 µm and electrically driven by well mechanical designed metallic thin film electrodes. Multiple electrodes in the robots in charge of individual segments control allow the soft robots exhibiting similar functionalities of animals or plants (for example, imitating the tongue of a reptile, such as chameleon to hunt moving preys, and mimicking vines to tightly wind around objects). These bionic results in the soft robots demonstrate their advantages in precise and flexible operation, which provides a good reference for the future research of intelligent soft actuators and robots.

Published: March 2021

AbstractDion–Jacobson (DJ) 2D hybrid perovskite semiconductors offer improved environmental stability and higher structural diversity in comparison with their 3D analogous. However, lacking of controlled perovskite crystallization makes it a challenge to achieve high charge transport for photovoltaic devices. Here, a detailed understanding of effects on film formation during different solution‐casting processes for the DJ perovskite (PDMA)(MA)n−1PbnI3n+1 (<n> = 4, PDMA refers to 1,4‐phenylenedimethanammonium) in the final film structure and photovoltaic outcomes is presented. Faster removal of solvent from solution via hot‐casting or antisolvent dripping results in a more uniform thickness distribution of quantum wells. This eventually enhances carrier transport greatly along perpendicular direction and increases power conversion efficiencies. A high efficiency of 15.81% is achieved for the hot‐casting devices, which is also the highest for aromatic spacer‐based DJ perovskite solar cells. This work helps to better understand the control of film formation during solution‐casting for high performance solar cells.
Piperidine‐Mediated [3+2] Cyclization of Donor‐Acceptor Cyclopropanes and β‐Nitrostyrenes: Access to Polysubsituted Cyclopentenes with High Diastereoselectivity
Authors: Xin Junhu , Dai Chenlu , Zhang Yue , Wang Cunde 
Published: March 2021

AbstractPiperidine‐mediated [3+2] cyclization of cyclopropane‐1,1‐dicarbonitriles and β‐nitrostyrenes was developed to generate highly diastereoselective polysubstituted cyclopent‐2‐ene‐1‐carboxamides with good yields. The approach involved cascade ring‐opening, cyclization, an amido bond formation from cyano group and adjacent cis‐cyano/aryl configuration, thus provided a new insight into the donor‐acceptor cyclopropane chemistry for the synthesis of complex cyclic compounds.
Perioperative Care of Patients Diagnosed With Twin‐to‐Twin Transfusion Syndrome Undergoing Laparoscopic‐Assisted Fetoscopic Placental Laser Photocoagulation

Published: March 2021

ABSTRACTTwin‐to‐twin transfusion syndrome (TTTS) is a condition that results in unbalanced blood flow between two fetuses. Patients diagnosed with TTTS can experience maternal or fetal morbidity and mortality. Depending on the severity of TTTS, laser ablation of placental anastomoses may be the most effective treatment. The preferred treatment method requires percutaneous entry to the uterus; however, some patient circumstances (eg, placenta location) require a laparoscopic‐assisted procedure. During the preoperative appointments, clinicians assess the condition of the fetuses and patients may participate in genetic counseling. Intraoperative care involves an interdisciplinary team that may include a pediatric general surgeon, maternal‐fetal medicine specialists, an RN circulator, a scrub person, and an anesthesia professional. Perioperative nurses should have knowledge of the pathophysiology of TTTS, including its natural progression. They also should understand preoperative and intraoperative patient care requirements to provide safe and effective care for patients undergoing laparoscopic‐assisted fetoscopic placental laser photocoagulation procedures.

Abstract

The worldwide decline of marine forests, due to human impacts and climate change, emphasizes the need to develop and implement effective and sustainable solutions to restore these endangered habitats and to re‐establish the services they provide.
In this study, the ex situ restoration of Gongolaria barbata (=Treptacantha barbata), a Mediterranean subtidal habitat‐forming species of brown seaweed, was for the first time implemented in a marine protected area in the Adriatic Sea. Two restoration efforts were performed in 2019. The first was started in winter, after a marine heatwave that triggered early fertility, and the second in spring, when the species usually reproduces.
This study aimed to evaluate: (i) the disruptive effects of a thermal anomaly on the reproductive biology and performance in culture of G. barbata; and (ii) the impact of the grazing pressure on juveniles after the outplanting.
The first cultivation was more productive than the second, in terms of zygote release and germling growth. To mitigate the low efficiency of the second culture and to avoid prolonged highly demanding maintenance in the mesocosms, the cultivation period was extended outdoors using a structure suspended in the water column.
The modular frames conceived for outplanting G. barbata proved to be effective because of their easy operability and low cost. Controlling for herbivorous fish had significant positive effects on both juvenile survival and growth.
The outcomes highlighted that an unpredictable climatic event and fish grazing were major threats that impaired the restoration process of G. barbata. These stressors should be considered when developing plans to implement effective large‐scale restoration of canopy‐forming macroalgae.

Published: March 2021

AbstractPicric acid (PA) at low concentration is a serious water pollutant. Alongside, aliphatic amines (AAs) add to the queue to pollute surface water. Plenty of reports are available to sense PA with an ultralow limit of detection (LOD). However, only a handful of works are testified to detect AAs. A new fluorescent donor‐acceptor compound has been synthesized with inherent intramolecular charge transfer (ICT) character that enables selective and sensitive colorimetric quantitative detection of PA and AAs with low LODs in non‐aqueous as well as aqueous solutions. The synthesized compound is based on a hemicyanine skeleton containing two pyridenylmethylamino groups at the donor and a benzothiazole moiety at the acceptor ends. The detailed mechanisms and reaction dynamics are explained spectroscopically along with computational support. The fluorescence property of the detecting compound changes due to protonation of its pyridinyl centers by PA leading to quenching of fluorescence and subsequently de‐protonation by AAs to revive the signal. We have further designed logic circuits from the acquired optical responses by sequential interactions.

Published: March 2021

AbstractA straight‐forward approach for the synthesis of a dihydrofuro[2,3‐b]benzofuran derivatives has been achieved through a base‐mediated Michael addition of 1,3‐dicarbonyls to 2‐nitrobenzofurans followed by intramolecular cyclization. A variety of 1,3‐dicarbonyls, including cyclic as well as trifluoromethylated ones, have been subjected to react with 2‐nitrobenzofurans under optimal conditions, and the respective dihydrofuro[2,3‐b]benzofurans could be accessed in moderate to excellent yields.

Published: March 2021

AbstractKeratinase is an attractive industrial enzyme that can specifically catalyze keratin waste to obtain value‐added products. A challenge to the application of keratinase is improving catalytic capacity to achieve efficient hydrolysis. In this study, we effectively expressed the keratinase gene from Bacillus licheniformis BBE11‐1 in Bacillus subtilis WB600 based on pro‐peptide engineering. Partial deletion of the pro‐peptide sequence and the substitution of amino acid at the pro‐peptide cleavage site (P1) suggested that the “chaperone effect” and “cleavage efficiency” of the pro‐peptide determine the activity of the mature enzyme. Subsequently, seven target sites that can increase the activity of the mature enzyme by 16%‐66% were obtained through the multiple sequence alignment of pro‐peptides and site‐directed mutation. We further performed combinatorial mutations at six sites based on the design principle of three‐codon saturation mutations and obtained mutant 2‐D12 (236.8 KU/mg) with a mature enzyme activity of 186% of the original (127.6 KU/mg). Finally, continuous fermentation was carried out in a 5‐L bioreactor for 22 h, and the activity of the 2‐D12 mature enzyme was increased to 391.6 KU/mg. Most importantly, 2‐D12 could degrade more than 90% of feather waste into amino acids and peptides within 12 h with the aid of sulfite.

Published: March 2021

AbstractBackgroundRadiotherapy is one of the main strategies for the treatment of esophageal squamous cell carcinoma (ESCC). However, treatment failure often occurs due to the emergence of radioresistance. In this study, we report a key regulator of radiation sensitivity, termed TAB182 that may become an ideal biomarker and therapeutic target to overcome radioresistance.Materials and MethodsBy applying qRT‐PCR and immunohistochemical staining, the expression of TAB182 was detected in patient tissues. We next assessed the influence of TAB182 downregulation to radiosensitivity using clonogenic survival assay and γ‐H2A.X foci analysis in TE‐1, TE‐10, and radioresistant TE‐1R cell lines after ionizing radiation. To unveil the mechanism underlying, TAB182 interacting proteins were identified by mass spectrometry following co‐immunoprecipitation. Furthermore, flow cytometry and western blot assay were applied to validate the identified proteins.ResultsOur results demonstrated that the expression of TAB182 is higher in cancer tissues than normal tissues and elevated expression of TAB182 correlates with poor outcomes of postoperative radiotherapy. Downregulation of TAB182 sensitized cancer cells to ionizing radiation, particularly in radioresistant TE‐1R cells that spontaneously overexpress TAB182. Mechanically, TAB182 interacts with FHL2 to induce G2‐M arrest through wiring the CHK2/CDC25C/CDC2 signaling pathway. Finally, overexpression of shRNA‐resistant TAB182 restored the checkpoint and radioresistance.ConclusionTAB182 potentiates the radioresistance of ESCC cells by modulating the G2‐M checkpoint through its interaction with FHL2. Thus, TAB182 may become an ideal biomarker and therapeutic target of ESCC radiotherapy.

AbstractThe Ultrasound‐guided erector spinae plane block (US‐ESPB), used as an anesthesiological block for opioid‐sparing approach and for postoperative analgesia, could represent an involuntary cause of hemodynamic instability. This hemodynamic instability is accentuated by a greater diffusion of local anesthetic in the epidural space.

Published: March 2021

AbstractA one‐pot synthesis of aluminium‐containing mesoporous silica particles (Al‐MSPs) utilizing polyvinyl alcohol (PVA) as steric stabilization agent is reported. PVA prevents particle agglomeration even when the ionic aluminium source is present in the synthesis mixture. Silicon and aluminium sources were utilised completely, resulting in high yield and easy adjustment of the Si/Al ratio. The Al‐MSPs showed a spherical morphology, high surface area and were active for the liquid‐phase Beckmann rearrangement of cyclohexanone to caprolactam.
Secure communication with joint resource allocation, relay and jammer selection in OFDM‐based cooperative networks
Authors: Liu Qi , Xu Ding 
Published: March 2021

SummaryThis paper considers an orthogonal frequency division multiplexing (OFDM) based cooperative network, where a source node communicates with a destination node with the help of multiple intermediate nodes, in the presence of an eavesdropper. Each intermediate node is assumed to be able to act as a relay or a jammer to improve the physical layer security. The problem of joint subcarrier allocation, power allocation, and mode selection to maximize the sum secrecy rate is investigated. We first reformulate the problem of subcarrier allocation and intermediate node mode selection as a three‐sided matching game and propose an algorithm that achieves a stable matching. Then, the sum secrecy rate is further improved by proposing a heuristic algorithm to switch the modes of the intermediate nodes. Finally, an iterative power allocation algorithm is proposed. It is verified by simulation results that the proposed algorithm outperforms various benchmark algorithms such as the equal subcarrier allocation algorithm, the pure relay selection algorithm, and the random relay selection algorithm, especially when the transmit power limit is high and the number of intermediate nodes is large.

Abstract
Metformin is a glucose-lowering drug commonly found in municipal wastewater effluents (MWWEs). The present study investigated the chronic effects of metformin in early-life stages of the fathead minnow (Pimephales promelas). Endpoints assessed were growth, survival, and deformities. The larval gut microbiome was also examined using 16 S ribosomal RNA gene amplicon sequencing to determine microbial community composition and alpha and beta diversity. Eggs and larvae were exposed to metformin measured concentrations (mean [standard deviation]) of 0.020 (0.017) μg/L (for controls) and 3.44 (0.23), 33.6 (1.6), and 269 (11) μg/L in a daily static-renewal setup, with 20 embryos per beaker. The low and middle metformin exposure concentrations represent river and MWWE concentrations of metformin. To detect small changes in growth, we used 18 replicate beakers for controls and 9 replicates for each metformin treatment. Over the 21-d exposure (5 d as embryos and 16 d posthatch [dph]), metformin did not affect survival or growth of larval fish. Hatch success, time to hatch, deformities in hatched fry, and survival were similar across all treatments. Growth (wet wt, length, and condition factor) assessed at 9 and 16 dph was also unaffected by metformin. Assessment of the microbiome showed that the larvae microbiome was dominant in Proteobacteria and Firmicutes, with small increases in Proteobacteria and decreases in Firmicutes with increasing exposure to metformin. No treatment effects were found for microbiome diversity measures. Control fish euthanized with the anesthetic tricaine methane sulfonate had decreased alpha diversity compared to those sampled by spinal severance. This experiment demonstrates that metformin at environmentally relevant concentrations (3.44 and 33.6 μg/L) and at 10 times MWWE concentrations (269 µg/L) does not adversely affect larval growth or gut microbiome in this ubiquitous freshwater fish species.
