Fabric Attractiveness Using Four Sensory Evaluators
Authors: Kodžoman Duje , Čok Vanja , Podlesek Anja , Čuden Alenka Pavko
Published: October 2023

All senses elicit emotional responses to goods, services, and the environment. They also play an important role in the process of fashion design and its evaluation. This research is a continuation of several preliminary studies we conducted online to define three attractive and three unattractive colors, textures, smells, sounds, and tastes. In the present study, a sample of textile engineering and fashion design students and experts (N = 54) assessed four groups of 6 fabric samples (sensory evaluators) selected based on the results of the preliminary studies. Each group of fabrics was assessed in one of four sensory modalities (except taste). Two semantic differentials were used to assess each sensory modality: attractive/unattractive and boring/interesting in the case of color, insensitive/sensitive in the case of texture, disturbing/calming in the case of sound, and cheap/luxurious in the case of smell. We found that among the fabrics in six different colors, the pink fabric was the most attractive. Of the six textures presented, the knitted rib texture was found to be the most attractive to touch. The scent of lemon essential oil was perceived as the most attractive among the six scents used, and the friction sound of suede leather was perceived as the most attractive among the six friction sounds of fabrics. Cluster analysis showed that the attractiveness of scents and colors of six fabric samples was highly differentiated and (almost) each sample was perceived as unique, while the attractiveness of the texture and sound of different samples was less differentiated and the samples were divided into only two groups. This suggests that discrimination of fabric attractiveness may be better in some sensory evaluators/modalities than in others. The results of this study will be useful for further research on the integration of different sensory modalities in fabric perception and garment preferences.
Re-evoking absent people: what languaging implies for radical embodiment
Authors: Cowley Stephen J. , Fester-Seeger Marie-Theres
Published: October 2023

Re-evoking examines how languaging enacts human social intelligence. Turning from linguistic tradition, we reduce language to neither abstracta nor form. Rather, as human activity, languaging enables people to co-act as they direct attention within what Margolis (2010b; 2016) calls an enlanguaged world. Given their embodiment, people use languaging to evoke absent others in a flow of action, feeling, judgment, and attitudes. Although based on organism-environment coupling, languaging is also activity that re-evokes the absent. In an enlanguaged world, people use emplaced activity as part of practices, events, situations, artifacts, and so on. Hence, people reach beyond the body as they re-evoke the absent by languaging or, by definition, “activity in which wordings play a part.” As we suggest, absent people are evoked by othering. In common domains (e.g. a school), social habits give rise to dispositions during a history of co-acting that, later, can re-evoke absent others and past selves. Having begun with a literary example, we later turn to a detailed case study to show how a narrator brings feeling to languaging (in this case, frustration) as she re-evokes other people as they are for her. In conclusion, we suggest that radical embodiment needs to be extended to include how human practices link coupling with social intelligence as people channel what they do with the help of languaging.

Published: October 2023

The introduction of new effective road construction materials for pavements and foundations of highways is an urgent task, including the development and application of resource-saving technologies aimed at the use of low-demand, large-tonnage mineral materials, semi-finished products, industrial waste, and their by-products. Research on this topic has shown that sulfur and sulfur-containing waste, as well as modified technical sulfur when used as a binder, should be widely used in sulfur structural and road concrete in liquid, granular, or lumpy form. Ferrous cakes from the Pobug Nickel Plant or “tailings” of sulfur ore flotation can be used as fillers for sulfur binder. Having a high specific surface, they will have a positive effect on the structure formation of sulfur during the crystallization of the melt in the direction of strengthening the structure. Their high acid resistance should significantly increase the corrosion resistance of sulfur concretes. Granular slag from a metallurgical plant can be used as a fine aggregate. Overburden rocks in the form of gabbro-dolerites, dolerites, and basalts can be used as acid-resistant large aggregates. To reduce the fragility of the sulfur binder, plasticizing additives such as naphthalene, chlorinated paraffin, and bitumen can be introduced. The results obtained in this study confirm a decrease in the cost in the production of asphalt and cement concrete and the possibility of expanding the range of building materials with new road-building mixtures. Also, the test results showed that when temperature was decreased, the strength characteristics of sulfur concrete in the temperature range 0°C to −60°C increased by 7%. Low water absorption of sulfur concrete (0.1%–0.3%) versus cement concrete (2%–4%), which positively affected the strength and operational characteristics, was revealed.
Simulation of the influence of cutting speed and feed rate on tool life in hard turning of AISI 4140 steel
Authors: Paengchit Phacharadit , Saikaew Charnnarong
Published: October 2023

Tool life performances of Al2O3+TiC and TiN+AlCrN tool inserts were investigated experimentally under different cutting conditions in turning AISI 4140 steel. The tool life model is defined in accordance with a maximum surface roughness of 0.8 μm for the tool life criterion. The relationships between machining factors (i.e., cutting speed and feed rate) and tool life were obtained by Taylor’s formular. The sensitivity of cutting speed and feed rate to tool life was evaluated by Monte Carlo simulation. The results showed that turning with high cutting speeds and feed rates decreased the tool life of both inserts. At different cutting speeds and feed rates, Al2O3+TiC exhibited better tool life performance than TiN+AlCrN. In addition, the simulation results indicated the average tool life of Al2O3+TiC was approximately 40% greater than that of TiN+AlCrN by varying cutting speeds below and above the cutting speed of 220 m/min while keeping the feed rate constant at 0.06 mm/rev. Similarly, when keeping the cutting speed constant at 220 m/min, the average tool life of Al2O3+TiC was approximately 45% greater than that of TiN+AlCrN by varying feed rates below and above the feed rate of 0.06 mm/rev. Variations of tool life values by varying cutting speeds were more sensitive than those by varying feed rates for both tool inserts.

Authors: Rauschnabel Philipp A.
Published: October 2023

Augmented reality (AR) is gaining recognition among executives as a powerful marketing tool. Unlike virtual reality, AR integrates virtual content into the real world, providing consumers with interactive experiences. AR applications like IKEA Place and Dulux Visualizer allow users to visualize furniture or paint colors in their homes, while AR games like Pokémon Go generate new revenue streams. The increasing availability of AR capabilities in smartphones and the creation of efficient developer tools have contributed to ist breakthrough. AR offers various levels of local presence, ranging from simple overlays to highly immersive mixed-reality experiences. The potential of AR extends beyond virtual reality, as it can create a new form of integrated three-dimensional Internet. AR marketing can enhance brand evaluations and emotional consumer-brand relationships, particularly through inspiration and closeness. Companies should consider AR as a tool for branding, as it has shown positive effects on brand attitudes, product evaluations, purchase intentions and word-of-mouth. Managers are encouraged to experiment with AR to understand ist potential and stay competitive in the evolving digital landscape.
Villismo y Revolución en la literatura posrevolucionaria de Nellie Campobello (1931-1960)
Authors: Olague Méndez María del Carmen
Published: October 2023

Este artículo propone analizar la idea de Revolución a través de la obra de Nellie Campobello escrita entre 1931 y 1960: Cartucho, Las manos de mamá, Apuntes sobre la vida militar de Francisco Villa y Prólogo a Mis libros. Este trabajo sostiene que la idea de Revolución de Campobello era indisociable al Norte de México y al villismo, más que por ideales políticos, por haber compartido con los villistas el mismo tiempo y espacio en su adolescencia. Para analizar esta relación entre el sujeto, el tiempo y el espacio, se decidió emplear la categoría de análisis cronotopo creador de Mijail Bajtín para dar cuenta de la influencia del mundo social en la autora y en su escritura.

La Literatura requiere de multiplicar el interés sobre ella a través de su enseñanza, que la concibe como un objeto de conocimiento, capaz de propiciar las claves para profundizar en los saberes sobre el rico y variado entramado, actual y futuro, de cultura-sociedad. Tal enseñanza, en su carácter relacionado con la historia, o lo que es igual, a una perspectiva y orientación interdisciplinaria, puede y debe contribuir a ese propósito. Las posibilidades ofrecidas por la novelística histórica y/o de fuertes vínculos con la historia para trabajar dichas relaciones son de gran importancia en todos los niveles de enseñanza. Esta, más que ninguna otra tipología novelística, resulta una fuente especial de saber histórico, susceptible de ser aprovechada para el conocimiento del pasado, el presente y de la proyección del ser humano, al menos hacia el futuro mediato. Asimismo, contribuye a la formación de una cultura humanística en los y las estudiantes, con la consiguiente prefiguración de valores éticos y estéticos, y lo que es mejor aún, a la creación de valores ideo-políticos, al entrar los y las alumnas en contacto con la memoria histórica de los pueblos.

Extinguishing and Combustion Characteristics of Electrically Controllable Solid Propellants Under Elevated Pressures
Authors: Gobin Bradley , Reiter Paul , Whalen Sean , Young Gregory
Published: October 2023

An experimental study was conducted on electrically controllable solid propellants (ECSPs) created using a polyethylene oxide polymer binder, lithium perchlorate, and multiwalled carbon nanotubes. The propellants decompose and ignite shortly after the application of a voltage potential and extinguish when the voltage is removed under atmospheric conditions. The ignition delay as a function of the applied voltage magnitude was determined for a range of ECSP compositions. Pressurized experiments were conducted in an optically accessible strand burner to characterize the burning properties of the ECSPs as a function of pressure and electrical power. Additional experiments were conducted at elevated pressures where the voltage potential was removed and reapplied to extinguish and reignite the propellant and determine the self-extinction limits of the ECSPs. The results demonstrate that small compositional changes can drastically impact the ability to extinguish the ECSPs at elevated pressures.

Authors: Omidire Kolapo
Published: October 2023

The emergence of the COVID-19 pandemic early in 2020 has had unexpected consequences on virtually all aspects of human development, particularly businesses. Regrettably, the economies of most African countries are in a fragile state, and that fragility has had an effect on entrepreneurship, and in particular, small businesses that experienced the full brunt of the pandemic. This article seeks to examine the concept of corporate social responsibility (CSR), with a view to re-appraising the role of businesses, and to determine the extent to which CSR could facilitate post-pandemic socio-economic restoration and boost economic growth. To achieve this objective, the author engages in a qualitative study comprising a review of primary and secondary sources relating to CSR and its other variants. The role of CSR and how it can drive productive entrepreneurship, focusing on the two leading economies in Africa, namely South Africa and Nigeria will be examined. This is done with a view to making recommendations on the potential role of CSR in driving post-pandemic productive entrepreneurship, enhance sustainable development in society, and facilitate socio-economic restoration in a post-COVID-19 environment.

Published: October 2023

Changes in land use in Teluk Empening have an impact on recovering infiltration capacity, loss of land cover, forest fires and drainage of peatlands, which can affect the climate. This research was conducted to determine the effect of drainage channels on the microclimate in rubber fields. The Mann Whitney test was carried out with the results that it can be concluded that there is no significant difference between the distance of the drainage canal and the high groundwater table in peatlands designated for rubber fields. Measurement of soil temperature and moisture showed that the temperature of the rubber plantation is close to drainage then the soil moisture is dry and if the measurement is far from drainage it indicates wet soil moisture. The ground water level obtained ranges from 29 – 64.5 cm which is influenced by the tides of the drainage channel in the morning and evening. At a distance of 20 m from the drainage canal, the groundwater level is higher than the measurements made at a distance of 100 m. This shows that the existence of drainage has a direct impact on changes in suhu and temperature of the soil

ML-aided computational screening of 2D materials for photocatalytic water splitting
Authors: Wang Yatong , Sorkun Murat Cihan , Brocks Geert , Er Süleyman
Published: October 2023

The exploration of two-dimensional (2D) materials with exceptional physical and chemical properties is essent ial for the advancement of solar water-splitting technologies. However, the discovery of 2D materials is currently heavily reliant on fragmented studies with limited opportunities for fine-tuning the chemical composition and electronic features of compounds. Here, we apply a combination of machine learning (ML) and physics-based computation to evaluate the V2DB digital library, which contains an extensive collection of 2D materials for their potential use in photocatalytic water splitting. To examine the structural and electronic properties of the potential 2D photocatalysts, we utilize a computational funnel approach that integrates ML modeling, as well as DFT, hybrid-DFT, and GW calculations. Our screening process yields a selection of 11 promising 2D photocatalysts. Consequently, our study not only unearths previously unexplored 2D potential photocatalysts but also introduces an effective screening methodology that may serve as a model for accelerating 2D materials discovery within a large chemical space.

Published: October 2023

Synthetic methods that enable the macrocyclization of peptides facilitate the development of more effective therapeutic and diagnostic tools. Herein we report a novel peptide cyclization strategy based on intramolecular interception of visible-light-mediated cysteine desulfurization. This method allows cyclization of unprotected peptides in an aqueous solution via the installation of a hydrocarbon linkage. We explore the limits of this chemistry using a range of model peptides of increasing length and complexity, including peptides of biological relevance. The method is applied to replace the native disulfide of the peptide hormone, oxytocin with a proteolytically/redox-stable hydrocarbon, and internal macrocyclization of an MCL-1-binding peptide.
Water DMSO Cosolvent Mixtures Modulate Hydrogen Bonding at a Gold Electrode Interface

Published: October 2023

Water often serves as both the reactant and solvent in electrocatalytic reactions. The interfacial water network can affect the transport and kinetics of these reactions, e.g., hydrogen evolution reaction and CO2 reduction reaction. Adding cosolvents that influence the hydrogen bonding environment, such as DMSO, has potential to tune the reactivity of these important electrocatalytic reactions through the regulation of the interfacial local environment and water network. We investigate interfacial hydrogen bonding networks in water DMSO cosolvent mixtures on gold surfaces using a combination of surface enhanced infrared absorption spectroscopy and molecular dynamics simulations. Experiments and simulations show that the gold surface is enriched with partially dehydrated DMSO molecules and the mixture phase separates to form water clusters. Simulations also show a “buckled” conformation for water at the surface that further constrains interfacial hydrogen bonding. The small size of these water clusters (<40 water molecules) combined with the energetically unfavorable hydrogen bond conformations might inhibit hydrogen bonding of interfacial water molecules with the bulk and suppress the proton diffusion required for efficient HER processes.

Published: October 2023

Catalytic degradation in proton exchange membrane fuel cells (PEMFCs) has always been a challenging subject. Despite the monumental research on the subject1-6, the complex relationship between the catalyst deactivation mechanisms and electrochemical degradation remains obscure owing to the heterogenous nature of the catalyst structure. Here we report a correlative electron and X-ray imaging method that enables a multi-modal and multi-length-scale quantification and visualisation of Pt degradation mechanisms in the oxygen reduction reaction (ORR) for proton exchange membrane fuel cell (PEMFC). This technique provides statistical information of up to 107 Pt nanoparticle with 2-dimensional (2D) statistical distribution of Pt content and nanoparticle number in length scales from 2 nm to 20 µm. With the accelerated durability test (ADT) under an O2-saturated 0.1 M HClO4 electrolyte between 0.4 and 1.2 V vs. reversible hydrogen electrode (RHE), the statistical results reveal that the carbon supported Pt nanoparticle catalyst experiences 1) 1:1.5 ratio between the type I degradation mechanisms, Pt dissolution and particle detachment, and type II, Ostwald ripening and particle agglomeration; 2) electrocatalytic activity losses of 33.4% and 41.8% for type I and II degradations, respectively; and 3) macro-scale Pt redistribution from Pt dense regions to sparse regions at an average distance of 1.6 ± 0.9 µm.

The use of phosphorescent luminophore is highly beneficial in diverse high-technological and biological applications. Yet, because of the formally forbidden character of intersystem crossing, the use of heavy metals or atoms is usually necessary to achieve high quantum yields. This choice imposes serious constraints in terms of high device cost and inherent toxicity. In this contribution we resort to density functional based surface hopping non-adiabatic dynamics of a potential organic luminophore intended for room-temperature applications. We confirm that intersystem crossing is operative in a ps time-scale without requiring the activation of large-scale movements, thus confirming the suitability of the El Sayed based strategy for the rational design of fully organic phosphorescent emitters.

The aim of this study is to adapt the Refugee Post-Migration Stress Scale (RPMS) to Syrian immigrants living in Türkiye and to determine the factors associated with RPMS. In this context, the WHO-5 Well-Being Index was administered with RPMS to 250 participants living in Mardin, one of Turkey's border provinces with Syria, for the study's first phase. In the second stage, RPMS and Multidimensional Perceived Social Support Scale were administered to 409 Syrians together with the demographic information form prepared by the researchers. According to the CFA results applied in the first stage, the psychometric properties of the adapted version of the scale were found to be satisfactory. In the second study, it was found that social support was negatively related to the post-migration stress levels of the participants and PMS differed significantly in terms of marital status, educational status, social support, income and employment status, language proficiency, hope for the future, and ethnicity variables. Study implications and limitations are discussed.

Las fracturas expuestas constituyen una de las principales emergencias médicas en el área de traumatología. Consisten en una lesión ósea, con exposición al ambiente exterior. Una de sus principales causas son los traumas de alto impacto. En consecuencia, son propensas a complicaciones tales como las infecciones, amputación o inclusive muerte. En cuanto a las pautas de manejo terapéutico suelen ser cambiantes, por lo cual, es fundamental mantenerse en constante actualización. En este sentido, el objetivo de la presente investigación es plasmar el manejo clínico y quirúrgico de las fracturas expuestas. El enfoque metodológico de la investigación es una revisión bibliográfico – documental, apoyado por diversas bases de datos, para la obtención de información relevante en base al tema de estudio. La clasificación de la fractura permitirá la elección del mejor abordaje. En la actualidad, la clasificación de Gustilo – Anderson sigue siendo la más usada. El manejo clínico y quirúrgico incluyen la antibioticoterapia, la profilaxis antitetánica, el desbridamiento, la fijación de la fractura, la analgesia, el cuidado y cierre de la herida. El reto en la actualidad del cirujano de trauma consiste, no en el simple salvamento de la extremidad sino restaurar la función máxima. En cuanto a la decisión de amputar, actualmente, el sistema más usado que permite la evaluación y consecuente toma de decisión es el MESS (Mangled Extremity Severity Score).

Mixed-mode stationary phases based on epoxidized copolymer of styrene and divinylbenzene have been obtained by amination with methylamine, further alkylation with 1,4-butanediol diglycidyl ether and opening the terminal oxirane rings with dimethylethanolamine. To evaluate the effect of the number of anchor amino and diol groups on the degree of hydrophilization of resins, the quantity of reagents was varied. Polymerization of glycidol in the functional layer at an increased pH of the reaction medium was carried out for additional shielding of the substrate. It was found that increasing the number of anchor amino groups is promising for increasing hydrophilicity in suppressed ion chromatography and hydrophilic interaction liquid chromatography modes, while polymerization of glycidol increases the degree of substrate shielding. The applicability of the most hydrophilic adsorbent in three HPLC modes was demonstrated. Novel mixed-mode stationary phase allows the separation of six nucleosides and nitrogenous bases by hydrophilic interaction liquid chromatography, 7 alkylbenzenes by reversed phase liquid chromatography, and 20 organic and inorganic anions by suppressed ion chromatography.

A high chemical resistance inherent in the alloys based on platinum group metals is one of the reasons for a number of difficulties that arise when dissolving such materials. Nowadays, the dissolution in aqua regia is one of the most effective methods for dissolving corrosion-resistant alloys. The main disadvantage of this method is a release of toxic gaseous substances such as nitrosyl chloride and nitrogen oxides. To decrease the volume of gases thus released without reducing the redox potential of the system, we proposed a method of dissolving a Pt – Rh alloy in HCl-HNO3 with a controlled dosed supply of HNO3 at a given value of the oxidation-reduction potential (ORP) of the system. The potential of the system has been chosen proceeding from the potential for HNO3 – HCl – Pt and HNO3 – HCl-Rh systems and amounted to 0.85 and 0.9 V. The impact of the dispersion and the inherent flaw of PtRh alloys on the dissolution indices of the alloy was also considered. It is shown that the dissolution of a Pt – Rh alloy with a rhodium content of 15 % in HCl – HNO3 at a constant value of ORP = 0.9 V compared to the use of the classic mixture (HCl:HNO3 = 1:3 vol.) provides a decrease in nitric acid consumption by 40%, reduction of the process time, increase in the recovery factor for both platinum and rhodium, and a two-fold reduction of the volume of released nitrogen oxides (theoretical calculation). It is also revealed that the process of mechanical activation of the alloy reduces the dissolution time and leads to almost quantitative dissolution of the sample.

Published: October 2023

Bean mosaic virus (BCMV) is a widespread plant pathogen that causes significant bean yield losses in several bean-growing regions worldwide. The use of resistant common bean varieties to BCMV is considered the most efficient and feasible approach to control its effects. Numerous genes and molecular markers associated with resistance to these pathogens have been discovered and used extensively in breeding studies around the world. Screening bean genotypes for resistance to these viruses is a critical step in developing resistant varieties. The goals of the study are to identify virus sources in the region and artificially inoculate Lake Van basin bean genotypes with BCMV. The recovered BCMV strain NL-4 was inoculated with 45 bean cultivars, most of which originated from the Lake Van basin in Turkey. Differentiation between resistant and susceptible was based on visual symptoms, and of the 45 genotypes, 29 were found to be resistant to NL-4, while 16 genotypes were susceptible (8 of them moderately susceptible and 8 of them highly susceptible).

Pulau Banyak and Pulau Banyak Barat Districts. play an active role in advancing capture fisheries production, this can be seen from the larger number and size of vessels operated so as to produce larger capture fisheries production. To land and sell their catch, many private entrepreneurs do it in their private holdings, not in government-owned fishing ports. This Tangkahan generally has relatively little land and facilities, but the activities and production are relatively large. This study aims to analyze the catch landed on the Tangkahans of Banyak Island, Aceh Singkil and make a map of the location of the Tangkahans in Pulau Banyak, Aceh Singkil. The method used is in 2 stages, the first stage is conducting a field survey using interview questionnaires, and the second stage is collecting field data (coordinate points of Tangkahan, types of catches and aerial photos of Tangkahan Island many). The location of the research is on Banyak Island, Aceh Singkil. The results of the study showed that there were 12 Tangkahans in Pulawa many, of which 8 units were in Baguk Village and 4 units were in Balai Desai. The catches that landed consisted of Squid, Dencis Fish, Tuna, Coral Anchovy and others. This is because the fishing gear used by Pulau Banyak fishermen is dominated by Bagan.
