La presencia de revistas españolas de psicología en diferentes bases de datos internacionales (JCR y SJR) es un indicador que determina el crecimiento y la madurez de esta disciplina y aporta una visión de la actividad científica en psicología y su situación en el contexto internacional. El objetivo del presente trabajo es determinar el papel del Colegio de Psicólogos como editor de revistas de psicología de impacto. Se seleccionaron 17 revistas indexadas simultáneamente en las bases JCR y SJR de 2018. Los resultados muestran como el 53% de éstas son editadas o coeditadas por un Colegio de Psicólogos, con especial relevancia del Colegio de Psicólogos de Madrid, teniendo una mayor presencia en otras bases de datos y un mayor número de revistas en los primeros cuartiles del JCR (SSCI), si bien no existen diferencias en el número de registros en los tres primeros cuartiles desde 1997 hasta la actualidad. Se puede concluir que las políticas de estado y las campañas de posicionamiento de universidades, asociaciones y colegios juegan un papel clave en la internacionalización y posicionamiento, y que en el caso español el Colegio de Psicólogos es el principal editor y promotor de una auténtica política orientada a estos fines.
The presence and spread of Spanish psychology journals in different international databases (JCR and SJR) is an indicator that determines the maturity and growth of this field, apart from providing an interesting view of the scientific activity for what concerns psychology and its situation within the international context. The objective of the present work is to determine the role of the College of Psychologists as editor of psychology high-impact journals. 17 indexed journals were simultaneously selected in the JCR and SJR databases. The results show how 53% of them are edited or coedited by a College of Psychologists, with the particular relevance of the College of Psychologists from Madrid, having this a higher presence in other databases and a higher number of 1st quartile journals in JCR (SSCI); however, there are no differences in the number of first quartile registers in the time span that goes from 1997 until now. We could conclude that the state policies and the ranking campaigns of universities, associations and colleges play a key role in internationalization and ranking, since, in the case of Spain, the College of Psychologists is the main editor and promotor of a true policy focused on these objectives.

Wheat is one of the most important staple grains in the world and the leading source of calories, production is limited by biotic stress. There is a number of pathogen attacks on wheat crops, depending on environmental conditions. In some cases, more than one crop pathogen attack leads to higher damage or decrease susceptibility. There are very few studies in the field of multiple pathogen interactions; in this study, we analyzed the co-infectionof wheat with fungal and bacterial pathogens. Field isolated Xanthomonas translucens and Xanthomonas compestris bacteria have been used against GM-322 and PDKV varieties co-infected with Fusarium fungus spp. In our experiment, we used Fusarium oxysporum, Fusarium graminearum, Fusarium equitus. Compared to the combined effect of the fungus and bacteria, we measured the length and width of the infected leaf part. We have observed that there is more susceptibility to X. compestris and F. graminearium in the GM-322 wheat variety. The second susceptible cvs was PDKV when we co-infected F. oxysporum and then X. translucens fungal and bacterial infected symptom analysis showed yellow stripes on the leaf surface of the wheat crop. We observed head blight in wheat when it was infected with F. graminearum and X. compestris. As a result, we concluded that varietal susceptibility also depends on co-infection pathogen attacks and their synergetic interaction.

Published: December 2019

In this study, cashew nut shell liquid has been extracted from cashew nut shells using an accelerated solvent extraction technique and was employed as a precursor for the synthesis of cashew nut shell liquid resin. The extract was a dark brown viscous liquid with an average yield of 30.61±0.200%. Results of the physical analysis showed a moisture content of 4.45±0.020% and a density of 0.95±0.300 gcm-3. The percentage brix and refractive index were 76.20±0.001 and 1.47 ±0.010 respectively. Chemical characterization showed a pH of 5.65±0.003; acid value of 8.25± 0.200 mg KOH/g; ash content of 1.80±0.6%; free fatty acid of 4.12±0.400 mg KOH/g; ester value of 247.01±0.100 mg KOH/g and a saponification value of 255.26±0.800 mg KOH/g. The FTIR spectra revealed that cashew nut shell liquid is polymeric. These findings confirm that higher phenolic compounds which can be used as potential precursors in industrial applications could be obtained from agro wastes.
Practical Applications: Cashew nut shell liquid, an extract from cashew nut shell, an agro waste has a wide range of functional products. A practical application is synthesis of a high viscous, flexible cashew nut shell liquid resin with physical properties that are consistent with literature and could also be further used in other industrial applications. Further processing of cashew nut shell for the development of value added products like resin can be a better option.

AbstractHighly‐crystalline Gd‐based fluoride upconversion (UC) nanocrystals, including orthorhombic‐phase GdF3:Yb/Er nanoplates (NPLs), hexagonal‐phase NaGdF4:Yb/Er NPLs, monoclinic‐phase K3GdF6:Yb/Er nanoribbons (NRs), and orthorhombic‐phase KGdF4:Yb/Er NRs are controllably synthesized through a simple yet robust method, with all of the products exhibiting strong UC luminescence. Notably, the obtained K3GdF6:Yb/Er NRs have an exceptional quantum yield as high as 0.84% at a low excitation laser power (0.30 W cm−2, 975 nm), as well as long single‐particle UC lifetimes (τ) for green (τ = 0.70 ms) and red (τ = 1.10 ms) emissions. The enhanced luminescence is attributed to the “multiple luminescent center effect,” which is verified via the laser‐selective excitation spectra of deliberately introduced Eu3+ dopants. This method can be extended to the preparation of a number of other nanocrystals, and the UC nanocrystals featuring high luminescence efficiencies can be further tailored for biomedical applications.

Published: December 2019

AbstractStretchable organic optoelectronic devices have been developed rapidly in the last few years due to their great potential in wearable electronics. Although high performance is obtained, high‐throughput manufacturing of these devices is still a challenge for their commercial application. Here, a roller‐assisted adhesion imprinting (RAI) technique is developed to overcome this challenge by rapid production of ordered and large‐area wrinkled structures on organic optoelectronic devices to enable their stretchability. Different from the conventional imprinting technology requiring heating or ultraviolet treatment, adhesion force is employed innovatively in the RAI process to form microstructures within the imprinted materials. As a demonstration, a stretchable wrinkled structure with its length of more than 10 cm is rapidly fabricated and larger area is available by continuous imprinting. Stretchable organic light‐emitting devices (SOLEDs) are easily manufactured by the RAI process. The SOLEDs can be elongated to 100% strain and keep working with 5% current efficiency variation after 35 000 cycles of stretching with 20% tensile strain. This is the best mechanical stability of SOLEDs reported to date. The development of the high‐throughput, large‐area, and cost‐effective RAI technique provides potential roll‐to‐roll continuous production of stretchable electronics.

ABSTRACTSubbituminous coal from the powder river basin was extracted with N,N‐dimethylformamide at atmospheric pressure to yield a solid extract that provided phenolic and carboxylic acid groups. The coal extract was employed as polyol in polyurethane (PU) synthesis. A solvent‐free synthesis using 2,4‐toluene diisocyanate (TDI) resulted in a porous PU solid. Reaction with TDI in solution resulted in a soluble PU that could be applied as adhesive or coating. Coatings were also prepared from coal extract solutions and commercial, polymeric isocyanates, providing excellent adhesion to aluminum. © 2019 Wiley Periodicals, Inc. J. Appl. Polym.

Published: December 2019

AbstractShewanella woodyi cultures were used to correlate bioluminescence intensity with changes in the electrochemical potential of a saltwater medium using soluble electron acceptors. A relationship between the concentration of NaNO3 or CoCl2 to bioluminescence intensity was confirmed using aerobic cultures of S. woodyi at 20°C with glucose as the sole carbon source. In general, increasing the concentration of nitrate or Co(II) reduced the bioluminescence per cell, with complete luminescence being repressed at ≥5 mM nitrate and ≥0.5 mM Co(II). Results from cell viability fluorescent staining concluded that increasing the concentration of Co(II) or nitrate did not affect the overall viability of the cells when compared with cultures lacking Co(II) or nitrate. These data show that potentials of <0.2 V vs Normal Hydrogen Electrode (NHE) repress the luminescence from the cells, but the exact mechanism is unclear. Our results indicated that the luminescence intensity from S. woodyi could be systematically reduced using these two soluble electron acceptors, making S. woodyi a potential model bacterium for whole‐cell luminescence bioelectrochemical sensor applications.

AbstractBackgroundPrevious studies indicated that type 2 diabetes mellitus (T2DM) is related to an increased lung cancer risk, but its role in the prognosis of NSCLC remains conflicting. This study investigated the impact of blood glucose control on the outcomes in NSCLC patients with T2DM treated with platinum‐based doublets.MethodsClinicopathological and survival data from 191 T2DM patients with advanced NSCLC, who received platinum‐based chemotherapy, were retrospectively analyzed. Based on the blood glucose conditions during chemotherapy, patients were classified into poor (n = 84) and good control (n = 107) groups. Progression‐free survival (PFS) was assessed using the Kaplan‐Meier method.ResultsThe median PFS among patients with good glycemic control [197.0 (95% CI: 136.3‐257.7) days] was longer than that among those with poor control [132.0 (95% CI: 112.5‐151.5) days] (P = .0003). Further subgroup analysis of lung squamous carcinoma and adenocarcinoma patients showed that the median PFS of the good control group was also significantly longer than that of the poor control group [179.0 (95% CI: 78.4‐279.6) days vs 125.0 (95% CI: 110.9‐139.1) days, P = .0014; 197.0 (95% CI: 124.3‐269.7) days vs 154.0 (95% CI: 129.9‐178.1) days, P = .0359; respectively]. The incidence rates of side effects were similar among patients with good glycemic control and those with poor glycemic control (all P > .05).ConclusionsSatisfactory glycemic control during platinum‐based chemotherapy might provide a survival benefit to T2DM patients with NSCLC. Further studies are warranted to confirm our findings.

Published: December 2019

AbstractPhotoelectrochemical water oxidation or oxygen evolution reaction (PEC‐OER) at the semiconductor surfaces has attracted huge attention over the years as it plays key role for energetically demanding processes like fuel cells, water splitting, and rechargeable metal‐air batteries. Thus, development of sustainable, abundant and economical semiconductor nanomaterials as the catalyst for photoelectrochemical water oxidation reaction is very challenging in achieving high efficiency in the overall water splitting reaction. Herein, we report a new porous Ni−W mixed metal phosphonate material NiWPPA‐4 with open framework structure through simple hydrothermal route and its crystalline framework has been indexed into a new orthorhombic crystal with unit cell dimensions: a=14.5506 Å, b=17.6445 Å, c=20.1766 Å and α=β=γ=90°. NiWPPA‐4 has been successfully utilized for photoelectrochemical OER from moderately basic medium [1(M) KOH] under constant irradiation of 100 mWcm−1 light source. Semiconducting property together with nanoscale porosity in the Ni−W mixed metal phosphonate is responsible for photoelectrochemical OER in alkaline pH. To the best of our knowledge it is the first report on a mixed metal phosphonate material, which showed excellent catalytic activity in the photoelectrochemical OER. The onset‐potential of NiWPPA‐4 prepared over ITO coated glass was only −410 mV vs Ag/AgCl and the oxygen evolution rate is 275 μmol g−1. This study thus established efficient photoelectrochemical OER on porous mixed‐metal phosphonates and offer opportunities for the utilization of metal phosphonates as potential photocatalyst in the energy conversion processes.

Published: December 2019

SummaryThe article herein briefly introduces the story of the birth of click chemistry and its evolution after that. A new angle to interpret click reactions was proposed using the “reactivity‐availability‐functionality” trilogy. CuAAC (Copper‐catalyzed azide‐alkyne cycloaddition), the most popular click reaction by far, was revisited along with the thiol‐ene, metal‐free AAC, SuFEx (Sulfur(VI) fluoride exchange) and the lately discovered diazotransfer process. By encountering more and more near‐perfect reactions, click chemistry is evolving and expanding on the fringe of the chemistry and different scientific disciplines, destination unknown.

Published: December 2019

SummaryTile art image generation is one of the non‐photorealistic rendering methods. The generated digital image resembles artistic representation given digital photos and illustrations. The first contribution of this paper is to propose a tile image generation based on the greedy approach. The greedy approach is based on the characteristic of the human visual system to optimize generated images. In addition, to shorten the computation time, we show the parallel algorithm and its GPU acceleration technique. We have implemented it on NVIDIA Tesla V100 GPU. The experimental result shows that the GPU implementation attains a speed‐up factor of 318 and 16.19 over the sequential CPU implementation and the parallel multi‐core CPU implementation with 160 threads, respectively. The second contribution of this paper is to propose an approximation method using machine learning with deep neural networks. After learning the network with the tile art images generated by the greedy approach as training dataset, it can generate tile art images that well‐reproduce the original images with tile patterns. Moreover, we show an additional machine learning technique by repeating the forwarding computation for the generated tile art image as an input image. As a result, using this technique, we can generate a tile art images with clear shape of tiles.

AbstractMultipor WI is a mineral‐based interior insulation system with excellent insulation properties. It is dimensionally stable, vapor permeable, and nonflammable. In this paper the investigation of the processability and functionality of Multipor WI WLF 042 as an exterior insulation system is reported. On the campus of Technische Universität Kaiserslautern, a building was constructed with a new exterior insulation system of Multipor WI WLF 042, of 14 cm thickness. This insulation, which has so far only been used in the building interior, has a heat conductivity of λ = 0.042 W/(mK) and a density of ρ = 90 kg/m3. Its thermal expansion coefficient is α = 10–5/K and its specific heat capacity is c = 0.85 kJ/(kgK). It has a lower density and compression strength than Multipor mineral insulation boards for exterior use do.Temperature sensors were implemented in different layers of the building envelope, both in undisturbed areas and at thermal bridges. The building will be monitored for several years. First heat transfer simulations of two thermal bridges of the building demonstrate the excellent insulation properties of WI WLF 042. The investigation of the processability and functionality of Multipor WI WLF 042 as an exterior insulation system is presented. First simulations show the excellent insulation properties of the insulation. The building will be monitored for several years to provide data about the processability and functionality of Multipor WI WLF 042 as an exterior insulation system.
