O objetivo deste estudo foi analisar o desempenho do processo de infusão a vácuo (VIP) na fabricação de compósitos de fios de juta e resina poliéster em comparação ao processo de laminação manual (hand lay-up), considerando múltiplos atributos com apoio do Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS). O experimento envolveu a produção de compósitos de matriz de poliéster insaturado reforçados por fios de juta na forma de tecido plano. As medidas de desempenho foram a porosidade, resistência à tração, custos, redução de emissão da voláteis e a expectativa de contribuição social. Os pesos dos atributos foram determinados objetivamente a partir da informação disponível em cada critério na matriz de decisão com base na entropia da informação. O processo de laminação manual foi utilizado como referência de avaliação por ser considerado o processo convencional. Os resultados revelaram que os atributos com maior peso foram a redução de emissão de voláteis e a porosidade; que o processo VIP apresentou um desempenho superior ao processo hand lay-up; e que a TOPSIS foi apropriada a análise do problema.

TB332; 在复合材料叶片设计中,可利用弯扭耦合效应进行铺层优化设计,通过减小叶片气动弹性外形的改变来提高叶片结构的效率.将复合材料叶片简化为对称非均衡悬臂层合板,基于经典层合板理论提出刚度权值和载荷系数2个分析参数.并采用试验和有限元模拟分析了弯扭耦合效应中分析参数对结构变形的影响.进一步以刚度权值的可行域为约束条件,叶片曲率最小为目标函数,对含有0°,90°和±45°铺层的对称层合板进行分析计算,得到关于载荷系数的刚度权值最优路径.并以16层对称层合板为例进行了验证计算.通过对刚度权值最优路径的逆向计算,能够快速得到满足设计条件的最优铺层顺序.该方法可为复合材料叶片的铺层优化设计提供一定的参考和依据.

From the end of the thirteenth century to the first decades of the sixteenth century, Guyart des Moulins’s Bible historiale was the predominant French translation of the Bible. Enhancing his translation with techniques borrowed from scholastic study, vernacular preaching, and secular fiction, Guyart produced one of the most popular, most widely copied French-language texts of the later Middle Ages. Making the Bible French investigates how Guyart’s first-person authorial voice narrates translation choices in terms of anticipated reader reactions and frames the biblical text as an object of dialogue with his readers. It examines the translator’s narrative strategies to aid readers’ visualization of biblical stories, to encourage their identification with its characters, and to practice patient, self-reflexive reading. Finally, it traces how the Bible historiale manuscript tradition adapts and individualizes the Bible for each new intended reader, defying modern print-based and text-centred ideas about the Bible, canonicity, and translation.

The present work deals with the influence of wood dust namely Rosewood and Padauk in the jute fiber-based epoxy composites. The work involves the fabrication of four different laminates of jute-epoxy composites using hand layup process with varying proportions of Rosewood and Padauk wood dust fillers compared with the composite in the absence of filler. The characterization of the mechanical and thermal properties was carried out by tensile, compression, flexural, shore D hardness, impact and thermogravimetric analysis as per ASTM. It is inferred from the test results that the mechanical properties got enhanced by the fine distribution of Padauk wood dust particles by improved adhesion with the matrix. The coarse structure of Rosewood dust over the composite improved thermal stability. Scanning Electron Microscopy was utilized to study the fractured interfaces of the mechanically tested composites. Furthermore, the developed composites affinity towards moisture and biodegradation were studied using water adsorption and biodegradability tests.

Marketers frequently style food to look pretty (e.g., in advertising). This article investigates how pretty aesthetics (defined by classical aesthetic principles, such as order, symmetry, and balance) influence healthiness judgments. The author proposes that prettier food is perceived as healthier, specifically because classical aesthetic features make it appear more natural. In a pilot, six main studies and four supplemental studies (total N = 4,301) across unhealthy and healthy, processed and unprocessed, and photographed and real foods alike, people judged prettier versions of the same food as healthier (e.g., more nutrients, less fat), despite equal perceived price. Even given financial stakes, people were misled by prettiness. In line with the proposed naturalness process, perceived naturalness mediated the effect; belief in a \"natural = healthy\" connection moderated it; expressive aesthetics, which do not evoke naturalness, did not produce the effect (despite being pretty); and reminders of artificial modification, which suppress perceived naturalness, mitigated it. Given that pretty food styling can harm consumers by misleading healthiness judgments for unhealthy foods, managers and policy makers should consider modification disclaimers as a tool to mitigate the \"pretty = healthy\" bias.

Textile lattice sandwich composite (TLSC) with excellent debonding resistance has been widely investigated. In this paper, the preparation technology of TLSC was improved by foam filling technology, namely hand lay-up and vacuum infusion process, and the flexural properties were studied. The microscope images of TLSC specimens were observed. The structure and resin distribution of TLSC specimens prepared by the above technology was compared. Three-point bending experiments studied the bending properties of foam-filled specimens. The results show that the TLSC specimen prepared by the vacuum infusion process has more resin distribution and high-quality structural form. The obvious resin-rich region appears on the TLSC specimen prepared by hand lay-up. The foam-filling technology can significantly enhance the strength and stiffness of the structure.

In the last 20 years, the consensus about memory being essentially reliable has been neglected in favor of an emphasis on the malleability and unreliability of memory and on the public’s supposed unawareness of this. Three claims in particular have underpinned this popular perspective: that the confidence people have in their memory is weakly related to its accuracy, that false memories of fictitious childhood events can be easily implanted, and that the public wrongly sees memory as being like a video camera. New research has clarified that all three claims rest on shaky foundations, suggesting there is no reason to abandon the old consensus about memory being malleable but essentially reliable.

Although lay beliefs about hope have been studied extensively in college student populations, little is known about how working professionals understand hope. Accordingly, the present study examined lay beliefs about hope among healthcare workers through the prism of two prominent models of hope. A directed content analysis of healthcare professionals’ qualitative responses indicated that the top seven most prevalent lay beliefs about hope were: cognition, implicit goal, agency thoughts, future orientation, likely, affect, and pathway thoughts. Consistent with the dominant perspective in the hope literature, Snyder’s Hope Theory, the three key ingredients of hope—agency thoughts, pathway thoughts, and goals—were all present, albeit to varying degrees. Aspects of Herth’s hope model, another prominent conceptualization, were less supported by our findings. When examining whether agency thoughts or pathway thoughts were more prevalent, there were no significant differences. When examining whether cognition or affect were more prevalent, there was a significant difference such that lay theories of hope typically reflected cognitive rather than affective processes. We discuss implications for existing hope models, implications for healthcare professionals, and future research avenues.

Being moved has received increased attention in emotion psychology as a social emotion that fosters bonds between individuals and within communities. This increased attention, however, has also sparked debates about whether the term \"being moved\" refers to a single distinct profile of emotion components or rather to a range of different emotion profiles. We addressed this question by investigating lay conceptions of the emotion components (i.e., elicitors, cognitive appraisals, subjective feelings, bodily symptoms, and consequences for thought/action) of \"bewegt sein\" (the German term for \"being moved\"). Participants (N = 106) provided written descriptions of both a moving personal experience and their conceptual prototype of \"being moved,\" which were subjected to content analysis to obtain quantitative data for statistical analyses. Based on latent class analyses, we identified two classes for both the personal experiences (joyfully-moved and sadly-moved classes) and the being-moved prototype (basic-description and extended-description classes). Being joyfully moved occurred when social values and positive relationship experiences were salient. Being sadly moved was elicited by predominantly negative relationship experiences and negatively salient social values. For both classes, the most frequently reported consequences for thought/action were continued cognitive engagement, finding meaning, and increased valuation of and striving for connectedness/prosociality. Basic descriptions of the prototype included \"being moved\" by positive or negative events as instances of the same emotion, with participants in the extended-description class also reporting joy and sadness as associated emotions. Based on our findings and additional theoretical considerations, we propose that the term \"being moved\" designates an emotion with an overall positive valence that typically includes blends of positively and negatively valenced emotion components, in which especially the weight of the negative components varies. The emotion's unifying core is that it involves feeling the importance of individuals, social entities, and abstract social values as sources of meaning in one's life.
