Authors: Marcos-Madrazo Aitor , Casado-Coterillo Clara , Iniesta Jesús , Irabien Angel
Published: August 2022

This work explores the potential of novel renewable materials in electrode fabrication for the electrochemical conversion of carbon dioxide (CO2) to ethylene in alkaline media. In this regard, the use of the renewable chitosan (CS) biopolymer as ion-exchange binder of the copper (Cu) electrocatalyst nanoparticles (NPs) is compared with commercial anion-exchange binders Sustainion and Fumion on the fabrication of gas diffusion electrodes (GDEs) for the electrochemical reduction of carbon dioxide (CO2R) in an alkaline medium. They were tested in membrane electrode assemblies (MEAs), where selectivity to ethylene (C2H4) increased when using the Cu:CS GDE compared to the Cu:Sustainion and Cu:Fumion GDEs, respectively, with a Faradaic efficiency (FE) of 93.7% at 10 mA cm−2 and a cell potential of −1.9 V, with a C2H4 production rate of 420 µmol m−2 s−1 for the Cu:CS GDE. Upon increasing current density to 90 mA cm−2, however, the production rate of the Cu:CS GDE rose to 509 µmol/m2s but the FE dropped to 69% due to increasing hydrogen evolution reaction (HER) competition. The control of mass transport limitations by tuning up the membrane overlayer properties in membrane coated electrodes (MCE) prepared by coating a CS-based membrane over the Cu:CS GDE enhanced its selectivity to C2H4 to a FE of 98% at 10 mA cm−2 with negligible competing HER. The concentration of carbon monoxide was below the experimental detection limit irrespective of the current density, with no CO2 crossover to the anodic compartment. This study suggests there may be potential in sustainable alernatives to fossil-based or perfluorinated materials in ion-exchange membrane and electrode fabrication, which constitute a step forward towards decarbonization in the circular economy perspective.

Published: August 2022

Three titanium alloys, Ti-10V-1Fe-3Al, Ti-10V-2Fe-3Al and Ti-10V-2Cr-3Al, were heated by solution treatment at in 700 °C (α + β phase region), 800 °C (near β phase region), 900 °C and 1000 °C (single β phase region). The effects of solution temperature on the microstructure and mechanical properties of the alloys were studied, and the mechanical asymmetry of tension and compression of three titanium alloys was analyzed; the results show that the microstructure of the three alloys changes regularly with the increase of solution temperature. Different solution temperatures have a significant effect on the compressive and tensile properties of the three alloys. During compression deformation, the stress-induced martensite transformation occurs in samples with solution at 800 °C and above; however, there is no phase transformation during the process of tensile tests. The asymmetry of yield strength, work hardening rate and final strength of the three alloys are obvious during compression deformation and tensile deformation. The difference in the number of twins between uniaxial tension and uniaxial compression, the presence or absence of stress-induced martensitic transformation, and the CRSS asymmetry of cone  slip may be the reasons for the asymmetry of mechanical properties.

Published: August 2022

In this study, the energy deposited at the welding interface was controlled by changing the stand-off between the flyer and base plates. Pure titanium (TP 270C) and duplex stainless steel (SUS 821L1) were welded under 5- and 15-mm stand-offs, respectively. When the stand-off was 5 mm, the average wavelength and average amplitude of the welding interface were 271 and 61 μm, respectively; at 15 mm stand-off, the average wavelength and average amplitude of the welding interface were 690 and 192 μm, respectively. The differences between the two welding conditions were compared using a tensile test, fracture analysis, a 90° bending test, Vickers hardness, and nanoindentation related to the mechanical properties of materials. The experimental results indicated that the sample with a 5-mm stand-off had better mechanical properties.

Published: August 2022

Owing to the excellent mechanical properties of the Ti3Al alloy, the study of its microstructure has attracted the extensive attention of researchers. In this study, a Ti3Al alloy was grown based on molecular dynamics using a decahedral precursor. Face centered cubic nanocrystals with tetrahedral shapes were formed and connected by twin boundaries (TBs) to form penta twins. To understand the shear response of the Ti3Al alloy with multiple and penta twins, a shear load perpendicular to the Z-axis was applied to the quenched sample. The TBs slipped as Shockley dislocations commenced and propagated under shear loading, causing the detwinning of the penta twins and the failure of the system, indicating that the plastic deformation had been due to Shockley dislocations. The slip mechanism of multi-twinned structures in the Ti3Al alloy is discussed in detail. This study would serve as a useful guide for the design and development of advanced alloy materials.

Nanocomposites of polyvinylidene fluoride (PVDF) with dimensional (1D) cobalt oxide (Co3O4) and f-MWCNTs were prepared successfully by the solution casting method. The impact of 1D Co3O4 filler and 1D Co3O4/f-MWCNTs co-fillers on the structural, thermal, and electrical behavior of PVDF were studied. The crystal structural properties of pure PVDF and its nanocomposite films were studied by XRD, which revealed a significant enhancement of β-phase PVDF in the resulting nanocomposite films. The increase in β-phase was further revealed by the FTIR spectroscopic analysis of the samples. TG, DTA, and DSC analyses confirmed an increase in thermal stability of PVDF with the addition of nano-fillers as well as their increasing wt.%. From impedance spectroscopic studies, it was found that the DC conductivity of PVDF increases insignificantly initially (up to 0.1 wt.% of nano-fillers addition), but a significant improvement in DC conductivity was found at higher concentrations of the nano-fillers. Furthermore, it was observed that the DC conductivity decreases with frequency. The increase in DC conductivity corresponded to the strong interactions of nano-fillers with PVDF polymer chains.

Published: August 2022

Past work has focused on the thermal properties of microscale/nanoscale suspended/supported graphene. However, for the thermal design of graphene-based devices, the thermal properties of giant-scale (~mm) graphene, which reflects the effect of grains, must also be investigated and are critical. In this work, the thermal conductivity variation with temperature of giant-scale chemical vapor decomposition (CVD) graphene supported by poly(methyl methacrylate) (PMMA) is characterized using the differential transient electrothermal technique (diff-TET). Compared to the commonly used optothermal Raman technique, diff-TET employs joule heating as the heating source, a situation under which the temperature difference between optical phonons and acoustic phonons is eased. The thermal conductivity of single-layer graphene (SLG) supported by PMMA was measured as 743 ± 167 W/(m·K) and 287 ± 63 W/(m·K) at 296 K and 125 K, respectively. As temperature decreased from 296 K to 275 K, the thermal conductivity of graphene was decreased by 36.5%, which can be partly explained by compressive strain buildup in graphene due to the thermal expansion mismatch.

Tephrosia is widely distributed throughout tropical, subtropical, and arid regions. This genus is known for several biological activities, including its anti-Candida activity, which is mainly attributed to prenylated flavonoids. The biological activities of most Tephrosia species have been studied, except T. apollinea. This study was conducted to investigate the underlying anti-Candida activity of T. apollinea, wildly grown in the United Arab Emirates (UAE). The T. apollinea plant was collected, dried, and the leaves were separated. The leaves were ground and extracted. The dried extract was subjected to successive chromatography to identify unique phytochemicals with a special pharmacological activity. The activity of the compound was validated by homology modeling and molecular docking studies. A novel steroidal compound (ergosta-6, 8(14), 22, 24(28)-tetraen-3-one) was isolated and named TNS. In silico target identification of TNS revealed a high structural similarity with the Candida 14-α-demethylase enzyme substrate. The compound exhibited a significant anti-Candida activity, specifically against the multi-drug-resistant Candida auris at MIC50, 16 times less than the previously reported prenylated flavonoids and 5 times less than the methanol extract of the plant. These findings were supported by homology modeling and molecular docking studies. TNS may represent a new class of Candida 14-α-demethylase inhibitors.

Published: August 2022

This study aims to analyze the relationship between perceived organizational culture (POC) and turnover intentions (TI) and if this relationship is mediated by perceived organizational support (POS) and job insecurity (JI). For this purpose, the following hypotheses were formulated: (1) POC (support, goals, innovation, and rules) has a negative and significant relationship with TI; (2) POC (support, goals, innovation, and rules) has a positive and significant relationship with POS (affective and cognitive); (3) POS (affective and cognitive) has a negative and significant relationship with TI; (4) POS (affective and cognitive) has a negative and significant relationship with JI; (5) JI has a positive and significant relationship with TI; and (6) POS (affective and cognitive) and JI both represent a serial indirect effect in the relationship between POC (support, goals, innovation and rules) and the TI. This study’s sample includes 661 participants working in organizations based in Portugal. The results indicate that only the perception of supportive and goal culture has a negative and significant association with TI; POC has a positive and significant association with POS; POS has a negative and significant association with JI and TI; JI has a positive and significant association with TI; affective POS and JI have a serial mediation effect in the relationship between supportive and goal POC and TI; cognitive POS and JI have a serial mediation effect in the relationship between goal POC and TI.
Changing Geographic Ranges of Human Biting Ticks and Implications for Tick-Borne Zoonoses in North America
Authors: Wikel Stephen
Published: August 2022

Ticks and tick-borne pathogens are increasing public health threats due to emergence of novel pathogens, expanding geographic ranges of tick vectors, changing ecology of tick communities, as well as abiotic and biotic influences on tick–host–pathogen interactions. This review examines the major human-biting ixodid tick species and transmitted pathogens of North America. Topics addressed include current and projected tick geographic ranges, potential risks for introduction of tick transmitted microbes into those regions, and drivers for these events. Health care providers, public health authorities, and the general public need to be aware of existing, resurging, and emerging tick and tick-borne disease threats. Knowing which ticks and tick-borne pathogens are present is foundational to understanding and responding to these threats. Dominant tick species and pathogens remain major foci of research, while limited attention has been directed to other human-biting ticks for decades, resulting in questions about current distributions, population sizes, and diversity of infectious agents they are capable of transmitting. Significant threats due to invasive ticks are considered. Recommendations are made for establishment of a sustained North America network for surveillance of ticks, characterization of their microbiomes and viromes, and for support of tick and tick-borne disease ecology research.
ACCUMULATION OF FREE WATER IN GAS SUPPLY SYSTEMS WITH LIQUEFIED GAS WITH INCREASED BUTANE CONTENT
Authors: Osipova N. , Kultyaev S.
Published: August 2022

The presence of free water adversely affects the operation of gas supply systems, causing corrosion of elements, the formation of vapor locks in pipelines, ice and hydrate locks at low temperatures, especially when using liquefied hydrocarbon gases with a high content of butanes. The quantitative characteristics of the operation of gas supply systems based on underground tanks when using gas with a high butane content are determined using the main provisions of the thermodynamic equilibrium of the vapor and liquid phases in the reservoir, the conditions for ensuring the minimum overpressure of the vapor phase for natural regasification of the product, the conditions for supplying the required amount of gas to the consumer for all domestic needs during the cold season. In result, the amount of accumulated moisture in the gas storage mode and the operation of tanks is determined. The minimum level of filling the tanks with the liquid phase and the number of gas refills per year are substantiated, while providing various utility needs depending on the climatic zone of operation and the characteristics of the gas supplied facilities. It is proven, when using liquefied hydrocarbon gases with a high butane content, taking into account the accumulation of moisture in the annual cycle of operation, it is recommended to use tanks with a volume of 5.0 m3 or more when using gas for all household needs, tanks with a volume of 1.0 m3 or more when using gas only for the purpose of food preparation.

Published: August 2022

A antropologia tem por objetivo estudar o homem levando em consideração seus costumes, ancestralidade, bem como caracteres incluindo o sexo, idade estatura e variações anatômicas. Dessa forma, o processo de identificação humana é de suma importância para o levantamento dessas informações e características, incluindo não só um indivíduo, mas também uma população. Sendo assim, o presente trabalho teve como objetivo determinar um padrão biológico na região de Maringá, assim como identificar o sexo a partir da medição de 83 pelves pertencentes aos acervos dos laboratórios de anatomia do Unicesumar e da Universidade Estadual de Maringá. As medições foram realizadas com o paquímetro digital, a régua e máquina fotográfica digital. Posteriormente os dados foram comparados para a determinação dos caracteres biológicos e também foram aplicadas as fórmulas de Rabbi para determinação do sexo. Os resultados obtidos acerca do perfil biológico foram conclusivos, sendo possível encontrar um padrão nas medidas, através da identificação de 41 peças do sexo feminino e 42 peças do sexo masculino. Apesar da intensa miscigenação que ocorreu na região e no Brasil como um todo, observamos diferenças métricas e observacionais entre as peças.

Introdução: Pacientes em estado crítico de saúde exigem tratamentos mais sofisticados e envolvimento concentrado de toda uma equipe de atendimento interdisciplinar. O ambiente das unidades de terapia intensiva é preparado e capacitado para atender estes pacientes com profissionais de saúde que lidam com alta acuidade e rápida tomada de decisão. O emprego dos cuidados paliativos, nesse contexto, visa melhorar a qualidade de vida destes pacientes quando as terapias curativas não são mais eficientes. Objetivo: O objetivo deste estudo foi avaliar o impacto dos cuidados paliativos nos pacientes internados em unidades de terapia intensiva. Metodologia: Foi efetuada uma busca bibliográfica para reunir os artigos sobre o tema em questão nas bases de dados SciELO, PubMed e Medline. Foram utilizadas as palavras-chave “cuidados paliativos” e “terapia intensiva” nos idiomas português e inglês. Desenvolvimento e Conclusão: Os cuidados paliativos concentram-se na prevenção e no alívio do sofrimento em pacientes no fim de vida quando a terapia curativa não é mais indicada ou eficaz. O recebimento de cuidados paliativos está associado a um tempo mais curto de internação e custos hospitalares mais baixos. Quando são iniciadas a aplicação da medicina paliativa, os médicos se tornam mais proativos e os familiares percebem que os enfermos obtiveram mais qualidade de vida. Na rotina de cuidados paliativos no ambiente de terapia intensiva, é importante fornecer suporte por meio da educação e informação, pois o fornecimento de informações como componente de cuidados de suporte muda a forma como as pessoas percebem e avaliam sua situação no contexto de cuidados intensivos.

O ensino de técnica cirúrgica veterinária é um processo complexo que abrange vários procedimentos sequenciais. Este envolve o conhecimento da anatomia, fisiologia, técnicas assépticas e cirúrgicas, que para sua plena realização necessitam de exercícios práticos semelhantes à arte operatória. O objetivo deste trabalho foi avaliar a vesícula urinária (VU) bovina para treinamento de técnicas cirúrgicas. Foram obtidas em frigoríficos, VUs bovinas isoladas dos demais órgãos descartados no abate, armazenadas sob refrigeração ou em freezer, seguido do descongelamento em temperatura ambiente. O treinamento consistiu na revisão anatômica, seguida da realização de duas técnicas de cistocentese e uma de cistotomia utilizando dois padrões de sutura de inversão distintos. As peças anatômicas foram consideradas eficientes em proporcionar aplicação das referidas técnicas durante as aulas práticas de técnica cirúrgica por docentes e monitores envolvidos. Durante o treinamento verificou-se a dedicação e motivação dos discentes, e concluiu-se que a VU bovina é método adequado para treinamento de técnica cirúrgica, de baixo custo, que permite a prática com experiência próxima do procedimento real quando a aquisição de cadáveres é fator limitante.

As a result of the decreasing availability of high-quality irrigation water, the salinity tolerance of cut flowers is of increasing importance. The influence of salinity on the growth and quality of Chrysanthemum, Chrysanthemum morifolium L. grown in two different media under four salinity levels was evaluated. C. morifolium plants were grown in plastic pots containing either zeolitic tuff or soil as potting media. Seedlings of C. morifolium were subjected to four NaCl/CaCl2 salinity levels (2, 4, 6, and 8 dS.m-1). The effect of increasing salinity level on growth, flowering characteristics, time to flower, length and diameter of flowering shoots, and the diameter of the terminal flower on each stem were evaluated. On termination of the experiment, plant height, two perpendicular canopy widths, and fresh and dry weights of shoots were measured. Results indicated that most of all measured characteristics were reduced in response to increasing salinity levels. Increasing salinity levels caused significant reductions in plant height, fresh and dry yield, and relative water content. Moreover, salinity reduced flower quality (color, size, stem thickness, and length) and yield. Also, some physiological changes occur in stomatal conductance, leaf relative water content, and chlorophyll content. C. morifolium plants showed a good salinity resistance by irrigating plants with saline water up to 4 dS.m-1. Significant differences in C. morifolium plant responses were also detected between soil and zeolitic tuff media for most tested characteristics, in which using zeolitic tuff as rowing media was better to cope with higher salinity levels than plants grown in soil. In conclusion, it is recommended to use zeolitic tuff instead of soil when water salinity is a problem in irrigation water.

Published: August 2022

The occurrence of the basidiomycete Amantia manginiana is reported for the first time in Jordan. The large crumbly white wild mushroom was collected from woodland during December 2014 from Dabouq in Jordan. All morphological characteristics including cap, stem, gills, and spores were recorded. The mycelium was isolated by aseptically removing a small part of the fruiting body and transferring it onto the potato dextrose agar plate. After four days of incubation at 25-30 °C in the dark, a pure culture was obtained. Sequence analysis of a partial fragment of 28S nuclear large subunit (nLSU) in the ribosomal RNA gene of the isolated strains included the new strain within taxon Amanita manginiana with 95% similarity to Genebank accession No. KP161281 and 91% to Genebank accession No. AF024463.1 respectively. According to morphological characteristics and molecular sequence analysis, the mushroom was identified as Amanita manginiana and recorded for the first time in Jordan.

Salah satu komoditas unggulan di Indonesia adalah budi daya udang dan beberapa pengusaha menjadikan udang ini sebagai komoditi ekspor seperti halnya kawasan Asia, Unit Eropa bahkan sampai Amerika. Berbagai jenis yang ada di Indonesia, udang vaname adalah salah satunya yang mempunyai nilai ekonomis yang cukup tinggi, selain itu ada juga udang putih dan udang windu yang cukup banyak peminat pasarnya. Nama lain udang vaname juga sering dikenal dengan nama udang putih. Beberapa keunggulan udang vaname adalah adaptasi yang tinggi terhadap cuaca, wilayah, maupun jenis air yang biasanya dapat mempengaruhi tumbuh kembang udang. Keunggulan terhadap adaptasi yang tinggi bisa menjadi nilai lebih bagi para petani tambak sebagai pilihan budidaya, dikarenakan dewasa ini perubahan yang sering dan cepat terhadap cuaca sedikit banyaknya mempengaruhi ekosistem yang ada. Namun minat yang tinggi terhadap budidaya udang vaname tidak diimbangin dengan pemerataan jalur distribusi pakan udang maupun pemasaran. Hal ini yang terkadang menjadi faktor utama tidak terkendalinya harga udang bahkan sulit untuk diprediksi. Terkadang harga udang dari pengepul terlalu rendah maupun terlalu tinggi yang berpotensi terjadinya permainan harga. Oleh Sebab itu diperlukannya sebuah penelitian terkait prediksi harga udang vaname sehingga dapat digunakan sebagai penentu ideal atau tidak ideal harga udang vaname. Penelitian ini menggunakan Algoritma Linear Regression yang mana adalah sebuah data statistik yang dapat memprediksi sesuatu kedepannya menggunakan data pada saat ini dan juga lampau, dengan metode pengukur keakuratan RMSE dan MAE dengan hasil penelitian ini masing-masing nilai RMSE 1932587 dan hasil MAE -0.01.

Standardization on Bias in Artificial Intelligence as Industry Support
Authors: Szczekocka Ewelina , Tarnec Christele , Pieczerak Janusz
Published: August 2022

Industry strives to have trustworthy AI systems, then to recognize and implement Responsible AI principles to achieve that goal. It is important for us to find solutions that will help implement trustworthy AI systems. Standardization activities are an important element for us in this regard, as they provide a platform for discussion for industry towards use and help work out practical rules and requirements. This article first provides an overview of the bias issue in Artificial Intelligence, and presents the concept of Responsible AI. Second, we present examples of interesting ongoing works by international  standardization organizations on bias in AI systems. Then we identify a gap between the principles defined by high-level legal studies on responsible AI, including the European AI Act proposal, and  practical implementations of these principles. Finally we state how international standardization may fill this gap. And perhaps the travel still to conduct to fill it?
Harmonic-aware Tri-path Convolution Recurrent Network for Singing Voice Separation
Authors: SHEN YIH LIANG , LAI YA CHING , CHI TAI SHIH
Published: August 2022

Temporal coherence and spectral regularity are critical cues for human auditory streaming processes and considered in many sound separation models. Some examples include the Conv-tasnet model, which focuses on temporal coherence using short length kernels to analyze sound, and the dual path convolution recurrent network (DPCRN) model, which uses two RNNs to analyze general patterns along the temporal and spectral dimensions on a spectrogram. In this paper, we propose a harmonic-aware tri-path convolution recurrent network (HATPCRN) model to separate singing voices on a spectrogram via the addition of an inter-band RNN, designed specifically for the harmonic structure. Evaluation results on the DSD100 and MUSDB18 datasets show that this addition can further boost separation performances of the DPCRN.
HIGH ENERGY DENSITY CELLULAR ELECTROSTATIC IN-PLANE 2-AXIS ACTUATORS
Authors: Palit Prithviraj
Published: August 2022

This work reports a class of silicon micromachined millimeter scale electrostatic actuator capable of both axial and lateral in-plane displacement with a relatively high energy density. The actuator is comprised of a large-scale integrated array of individual parallel-plate electrostatic cells. The force and displacement of cells within the array add up providing relatively large actuation force and displacement output for the actuators. The non-conventional fabrication process allows realization of submicron transduction airgaps within the actuator cells lowering the actuation voltage. The fabrication process also allows electrical isolation of different cells within the array so that different sections of the actuator ribbon can be actuated independently enabling lateral deformation of the actuator ribbon in addition to axial contraction. Axial in-plane displacement of up to 20.50 µm has been shown for a 2010 µm × 1000 µm fabricated actuator. The actuator output force is as high as 10.3 mN demonstrating maximum energy density of 1.11 mJ/cm3. The same actuator ribbon demonstrated lateral displacement of 10.11 um.
