Hyaluronic Acid Fibres in Solid Phase Peptide Synthesis — Their Properties, Morphology and Stability

Different methods and materials can be used for peptide synthesis. One of the most common approaches is synthesis on a solid phase. In this paper, we describe fibres based on hyaluronic acid (HA) and their properties under solid-phase peptide synthesis (SPPS) conditions. The fibres were prepared by wet spinning technology and were used to study their stability and mechanical properties under the reaction conditions for direct peptide synthesis or conjugation with a pre-synthesized peptide. Fibres in the form of a non-woven textile were then used as a proof of concept for the adhesion of cells on short cell-adhesion peptides. The methods, solvents and reaction conditions used showed no significant influence on the necessary stability of the HA fibres when the Fmoc/tBu strategy was applied. Furthermore, the stability of the HA fibres in aqueous solution was strongly improved. The stabilization and presence of cell-adhesive peptides supported the adhesion of cardiomyocyte cells, which confirmed the functionality of the modified textile. Therefore, HA carriers bearing peptides could be advantageously employed in various biomedical applications as repair patches.

The clothes that make you eat healthy: The impact of clothes style on food choice

Consumers often spend a considerable amount of time and resources on clothing, with the hope of influencing how others perceive them. Little is known, though, about how the clothes one wears might influence him/her to behave differently. This research examines the impact of clothes style (formal vs. informal) on consumers’ choice of healthy or unhealthy foods. We find that formal and informal clothes styles can activate different clothes-image associations and thus make consumers more likely choose a food type (healthy or unhealthy) that is congruent with a specific set of clothes-image associations, referred to as clothes-food congruence. For example, wearing formal clothes can activate such formal-clothes associations as being self-controlled and organized. Formal- (vs. informal-) clothes associations are perceived to be congruent with healthy (vs. unhealthy) food choices. Hence, we suggest that clothes-food congruence mediates the relationship between clothes-image associations and food choice. Implications for research as well as for practice are discussed.

Can Avatar Appearance Influence Physical Activity? User-Avatar Similarity and Proteus Effects on Cardiac Frequency and Step Counts

ABSTRACT This study combined user-avatar similarity and Proteus effect predictions to incentivize physical activity. 305 participants ran while wearing accelerometers and a heart rate monitor. They were randomly assigned to onscreen motion-capturing avatars displaying either participant or stranger faces dressed in sports or formal clothes. Participants assigned to avatars displaying their own face showed increased cardiac frequency compared with those exposed to avatars with a stranger’s face. Relative to the remaining conditions, participants assigned to avatars with their own face also wearing sports clothes showed increased cardiac frequency but participants assigned to avatars with a stranger’s face wearing formal clothes showed decreased cardiac frequency. The results imply that user-avatar similarity and the Proteus effect can be harnessed to influence physical activity.

Fabrication of piezoelectric poly(l-lactic acid)/BaTiO3 fibre by the melt-spinning process

Poly(l-lactic acid) (PLLA) based piezoelectric polymers are gradually becoming the substitute for the conventional piezoelectric ceramic and polymeric materials due to their low cost and biodegradable, non-toxic, piezoelectric and non-pyroelectric nature. To improve the piezoelectric properties of melt-spun poly(l-lactic acid) (PLLA)/BaTiO3, we optimized the post-processing conditions to increase the proportion of the β crystalline phase. The α → β phase transition behaviour was determined by two-dimensional wide-angle x-ray diffraction and differential scanning calorimetry. The piezoelectric properties of PLLA/BaTiO3 fibres were characterised in their yarn and textile form through a tapping method. From these results, we confirmed that the crystalline phase transition of PLLA/BaTiO3 fibres was significantly enhanced under the optimised post-processing conditions at a draw ratio of 3 and temperature of 120 °C during the melt-spinning process. The results indicated that PLLA/BaTiO3 fibres could be a one of the material for organic-based piezoelectric sensors for application in textile-based wearable piezoelectric devices.

손목 관절 거동 측정을 위한 착용형 센싱 수트 및 심층 신경망을 이용한 캘리브레이션 기법의 개발

A measurement of a users’ motion is widely attracting attention for a realization of robotic assistance in daily activities. The soft, wearable sensing suit enables the monitoring of outdoor activities, with high wearability and insensitivity to inertial force. In this paper, we propose a novel sensing suit for measuring the multi degree of freedom (multi-DOF) motion of the wrist joints. We used a fabric-based capacitance-type stretch sensor for high adaptivity to a textile form of suits. The sensor was attached to the body link, instead of the wrist joint to reduce the interdependency among each joint axis and the effect of unwanted disturbance. We adopted the Deep Neural Network for calibration, and verified the higher estimation accuracy on the estimation of the multi-DOF wrist motions. The performance validation proceeded with comparing to the linear-based regression, and the root mean-squared error on the angle measurement was improved at slow motion and fast motion. A real-time measurement interface was developed and demonstrated with a frequency of 250 Hz.

Basalt Textile-Reinforced Vinylester and Epoxy Resins for Anchors Used to Fasten Ventilated Building Facades

The aim of this work was to obtain insulation composite anchors based on basalt textile-reinforced vinylester and epoxy resins for fixing heavy building elevation cladding. It concerns the problem of applying materials not originating from wood, construction steel or concrete in the building industry. So far, the application of polymeric materials, including polymeric composites, in construction has been limited to paints, varnishes and glues, and the use of engineering polymers as building materials has been limited. This article presents a study on the influence of the type of basalt reinforcement (in the form of textile, chopped fibre and powder) on the mechanical and functional properties of vinylester and epoxy compositions towards potential applications as construction anchors to fasten building facades. Based on an analysis of the experimental results, a material was selected for the production of novel construction anchors. The results reported here constitute an introduction to further considerations related to the applications of vinylester resin/basalt and epoxy resin/basalt composites as construction materials alternative to commonly used steel and aluminium.

Can success deflect racism? Clothing and perceptions of African American men

ABSTRACT We examined the effect of different clothing styles on the perceptions of African American men. Using a between-group design, we tested whether participants perception of African American models wearing sweatpants and sweatshirts (“swagger”), clothing showing they won an event, or formal clothing, would vary. Participants (N = 143) viewed four African American models in one of three conditions. Multivariate analyses of covariance (MANCOVA) with Symbolic Racism Scale scores as a covariate revealed that participants rated models in Formal clothing significantly higher than models in winning clothing in intelligence, p <.001, trustworthiness, p <.001, and warmth p =.005. Models wearing formal clothing or winning clothing were also rated significantly higher than models wearing swagger clothing on several traits. Participant’s Symbolic Racism Score significantly affected their ratings of models. Results suggest that the clothing that an African American wears, as well as viewer prejudice, affects the impression that the viewer makes.

Passion Flower and Wheel of Fortune: An Oya Motif as an Example of Textile Form and Color Design

Oya—colorful handmade borders on headscarves—are still part of the traditional textile jewelry of Turkish women today. In this article, we use a not so common oya pattern to show how ideas of shape and color are implemented. The exact imitation of nature plays a special role, as does a certain degree of abstraction. An important criterion for the color selection is a special abundance of colors, on the one hand, and on the other a strong limitation to a few colors. It is shown how creativity, routine, and careful consideration are the prerequisites of high-quality and attractive craftsmanship.

Microbes of XVI century Arrases of Krakow Royal Castle

Sixteenth-century Arrases from the Krakow Royal Castle constitute a Polish national cultural heritage; hence, they should be under special protection. The storage of historic objects at strict temperature and humidity conditions is fundamental for their protection against microorganisms. However, sometimes active preservation must be applied to disinfect bio-contaminated objects. In this study, 39 strains of microorganisms, both fungi and bacteria, isolated from Arrases deposited in the Wawel warehouse were isolated and then identified using molecular tools. Fungal ability to colonize and degrade silk and wool laboratory samples was studied. Selected microbial strains were compared concerning their ability to affect silk fibroin using size-exclusion chromatography (SEC). The effectiveness of low-temperature helium-generated plasma in disinfecting the model wool and silk samples inoculated with selected strains was tested. The results showed that plasma, despite its high biocidal activity in the case of paper, was not effective on porous textile materials. The alternative protection mechanism, involving active packaging in the form of textiles impregnated with silver-exchanged zeolites, could be used to separate layers of rolled tapestries in the warehouse. Nevertheless, optimal temperature and humidity conditions should be strictly maintained and controlled.

Estimating Optimum Process Parameters in Textile Draping of Variable Part Geometries - A Reinforcement Learning Approach

Fine-tuning of manufacturing processes for optimum part quality requires many resource-intensive trial experiments in practice. To reduce the experimental effort, physics-based process simulations in conjunction with optimisation algorithms can be applied, e.g. finite-element-models and evolutionary algorithms. However, they generally require considerable numerical expertise and long computation times. Efficient optimisation of such expensive-to-evaluate models often employs surrogate-based optimisation (SBO). SBO constructs numerically inexpensive approximations of the original model, which guide the optimiser in the parameter space. This allows concentrating costly simulations on the most promising regions. While SBO significantly reduces the computational load in many cases, current SBO-strategies are inevitably problem-specific and cannot be reused in other, even similar situations. Consequently, subtle problem variations, e.g. minor geometry changes in material forming, require an entirely new optimisation and all previous numerical effort is in vain. Thus, surrogate techniques with generalised applicability are an open field of research. Machine Learning techniques using convolutional neural networks (CNNs) are capable of ‘learning’ complex system dynamics from data. In this work, CNNs are used to extend the predictive capabilities of SBO towards variable instead of fixed manufacturing settings. Specifically, material draw-in optimisation in textile forming (‘draping’) for variable geometries is studied. Using reinforcement learning, a CNN is trained to estimate optimum positions of pressure pads during draping of a pre-specified class of box-shaped geometries. Once trained, the CNN interprets a forming result and infers beneficial pad positions. Unlike conventional SBO strategies, it can also give recommendations for variable geometries from the selected geometry class. The paper shows that, in principle, CNNs are able to extract information from a range of different forming tasks and apply it to a new, unknown situation. Since they reuse information gained from previous simulations, they are considered a viable option for future, generalised SBO-strategies.

A 3D Modelling Approach for Fluid Progression during Process Simulation of Wet Compression Moulding – Motivation & Approach

Wet compression moulding (WCM) provides large-scale production potential for continuous fibre-reinforced structural components due to simultaneous infiltration and draping during moulding (viscous draping). Due to thickness-dominated infiltration of the laminate, comparatively low cavity pressures are sufficient – a considerable economic advantage. Experimental and numerical investigations prove strong mutual dependencies between the physical mechanisms, especially between resin flow and textile forming. Understanding and suitable modelling of these occurring physical mechanisms is crucial for process development and final part design. While existing modelling approaches are suitable for infiltration of preformed fabrics within various liquid moulding technologies, such as CRTM/RTM or VARI, WCM requires a fully coupled simulation approach for resin progression and concurrent stack deformation. Thus, the key challenge is to efficiently link these two aspects in a suitable framework. First, this work demonstrates that a three-dimensional approach for fluid progression during moulding is needed to capture WCM-process boundary conditions. In this regard, a novel test bench is used to investigate the impact of infiltration on the transversal compaction behaviour of a woven fabric. Moreover, the test setup is applied to determine the in-plane permeability values of the same material corresponding to the beforehand applied compaction states. Results are verified by comparison with an existing linear test setup.In the second part, initial steps towards a three dimensional extension of an existing 2D modelling approach are outlined. For this purpose, a macroscopic FE-based three-dimensional formulation of Darcy’s law is utilized within a User-Element in Abaqus/Explicit. Essential mechanisms within the element are presented. Additional control volumes (FE/CV) are applied to ensure mass conservation. Eventually, it is demonstrated, that the simulation model can predict the average fluid pressure beneath a punch during pre-infiltrated compaction experiments. Finally, major benefits and forthcoming steps for a fully-coupled 3D modelling approach for WCM are outlined.

Capabilities of Macroscopic Forming Simulation for Large-Scale Forming Processes of Dry and Impregnated Textiles

Forming of continuously fibre-reinforced polymers (CoFRP) has a significant impact on the structural performance of composite components, underlining the importance of forming simulation for CoFRP product development processes. For an integrated development of industrial composite components, efficient forming simulation methods are in high demand. Application-oriented method development is particularly crucial for industrial needs, where large and complex multi-layer components are manufactured, commercial FE software is used, and yet high prediction accuracy is required. To meet industrial demands, this contribution gives an insight in macroscopic forming simulation approaches that utilize the FE software Abaqus in combination with user-defined material models and finite elements. Three CoFRP forming technologies are considered, which are in industrial focus due to their suitability for mass production: textile forming of dry unidirectional non-crimp fabrics (UD-NCF), thermoforming of pre-impregnated UD tapes and wet compression moulding (WCM). In addition to the highly anisotropic, large-strain material behaviour that composite forming processes have in common, the three process technologies face various process-specific modelling challenges. UD-NCFs require material models that capture the deformation behaviour and the slippage of the stitching. Thermoforming of UD tapes is highly rate- and temperature-dependent, calling for rheological membrane and bending modelling. Moreover, a thermomechanical approach including crystallisation kinetics enables the prediction of potential phase-transition during forming and resulting defects in the semi-crystalline thermoplastic matrix. For simultaneous forming and infiltration in wet compression moulding, a finite Darcy-Progression-Element is superimposed with the membrane and shell elements for forming simulation, capturing infiltration-dependent material properties. The three outlined technologies illustrate the complexity and importance of further simulation method development to support future process development.

서울 소재 종합사립대학 UI(University Identity) 디자인의 이미지와 색상 변화 특성

Academic dress is a formal academical clothing for those who hold a status of academic degree, entitling them the authority and the responsibility of the degree and the society. It is also used as a communication tool to express the identity, tradition, and the future of universities. Thus, academic dresses are effective visual mediums that symbolize the school’s traditions, academic authorities, and status. UI(University Identity) is the expression or the visual elements of a university, which is crucial in enhancing the value of university brand. In modern society, universities are starting to shift their interests in establishing brands and creating their own UI. It is an intention to transform the university brand images according to the modern-day trends by consolidating the school symbols. As universities worldwide are becoming more brand-based, Dankook University, also, has managed to keep its own unique visual images based pride and dignity. Thus, this research and development of academic dress with UI for Dankook University aims in the development of academic dress as a cultural symbolic tool that contains the spirit of Dankook University. For the study, various design elements(color and variations, logotype, symbol mark, etc.), that express the roles and the visions of Dankook University, were applied as colors and details of the academic dress designs. In addition, the three academic designs that were suitable for the purpose of the study were developed into samples. Through the study, one wishes the academic dress to further develop as a symbolic expression of Dankook University’s identity and furthermore as a tool of communication and promotion of the university.

Humidity-resistant triboelectric energy harvester using electrospun PVDF/PU nanofibers for flexibility and air permeability

We present a triboelectric energy harvester fabricated with a simple electrospinning process of polyvinylidene fluoride/polyurethane polymers on conductive fabric. This electrospinning process provides higher electrical power output and hydrophobicity driven humidity resistance compared to flat polymer energy harvesters. By using conductive fabric as collector and electrode, the device could retain air permeability and flexibility. The triboelectric energy harvester exhibits a high open-circuit voltage of 45.1 V (at a compressive contact force of 20 N and relative humidity (RH) of 20%), humidity resistance (maintains about 40% of the open-circuit voltage at RH of 80%) and air permeability without deteriorating the air permeability of the fabric. Its durability was tested and shows no significant degradation of electrical output throughout 324,000 cycles of operation. This work suggests an approach for human energy harvesting in textile form with electrospun nanofibers as the contact surfaces of a triboelectric energy harvester.
