This study extends the current knowledge of behavioral intention of space travelers based on motivation and risk antecedents of undertaking a space trip. Using cumulative prospect theory, we develop ...and test research models to investigate sufficient motivation and risk antecedents on behavioral intention, to explore complex combinations of above antecedents (i.e., causal recipes) leading to both high and low scores of behavioral intention, and to identify necessary motivation and risk antecedents to achieve desired behavioral outcome. The results revealed that although motivations appeared as sufficient and necessary antecedents, risk antecedents play a dominant role such that risks can diminish the effects of motivations in shaping desired behavioral intention of space travelers. Theoretical and practical implications are discussed.
This paper attempts to define a visual culture of plate glass in Canadian exhibition buildings during the second half of the nineteenth century. I approach this material through descriptions and ...depictions in Canadian periodicals vernacular versions of the “Crystal Palace” exhibition building. In Canadian publications, their glass surfaces often take on certain metaphorical significance, coming to stand in for modernity, to signify purity by their clarity, or to promise a quintessentially modern honesty and openness, as their solid surfaces maintained visual limpidity. However, though glass is allusive in many ways, its signification also remained elusive. Any meaning that glass may encompass is always accompanied by its own opposite; glass can change in a moment from lucid to reflective, from refracting beams of bright light to darkening and dulling, and though it is a physically protective layer, it also permits unmitigated visual connection. The relationship of nineteenth-century Canadian periodicals to the material is marked by this ambiguity. I suggest that glass’s physical capacity for dualism is an apt metaphor for the way that the meanings it signified were often contradictory, even when simultaneous. I argue that in the context of these buildings, which intended to put the industry of Canada on display in the service of defining and asserting an emerging nationalism, the paradoxes encompassed by the developing cultural imaginaries around glass are mirrored by the paradoxes of Victorian Canadians’ ambiguous and conflicting relationships with nationalism and modernization.
Hundreds of image encryption algorithms have been developed for the security and integrity of images through the combination of DNA computing and chaotic maps. This combination of the two instruments ...is not sufficient enough to thwart the potential threats from the cryptanalysis community as the literature review suggests. To inject more robustness and security stuff, a novel image encryption scheme has been written in this research by fusing the chaotic system, DNA computing and Castle-a chess piece. As the plain image is input, its pixels are shifted to the scrambled image at the randomly chosen pixel addresses. This scrambling has been realized through the routine called Image Scrambler using Castle (ISUC). Castle randomly moves on the hypothetical large chessboard. Pixels taken from the plain image are shifted to the addresses of the scrambled image, where Castle lands in each iteration. After the plain image is scrambled, it is DNA encoded. Two mask images are also DNA encoded. Then to throw the diffusion effects in the cipher, DNA Addition and DNA XOR operations between the DNA encoded pixels data and the DNA encoded mask images have been conducted. Next, the pixels data are converted back into their decimal equivalents. Four dimensional chaotic system has been used to get the chaotic vectors. The hash codes given by the SHA-256 function have been used in the cipher to introduce the plaintext sensitivity in its design. We got an information entropy of 7.9974. Simulation carried out through the machine, and the thorough security analyses demonstrate the good security effects, defiance to the varied attacks from the cryptanalysis community, and the bright prospects for some real world application of the proposed image cipher.
This article adds to a growing interest within architectural studies in which the indoor climate and comfort of heritage buildings used for residence is in focus. The purpose is to understand how ...Skokloster castle in Sweden, built in the seventeenth century, has been shaped in relationship to needs and expectations of its residents. Building on a combination of archival sources, visual observations on site, printed sources and literature, this article demonstrates how a mix of methods can be used to investigate how castles have been adapted throughout history to fit changing expectations. By investigating how the castle was adapted over time light is shed on a much broader architectural history that includes not just the design and construction of a monumental building, but also how later interventions have aimed at making it more comfortable. Estimates of fuel consumption are made in order to better understand how the castle may have been heated. It is argued that the castle was not only built with the surrounding climate in mind, but that later uses of it as a residence also took careful note of how to efficiently use the architecture in order to make limited spaces inside the castle comfortable for living.

Sheffield Castle presents an original perspective on an urban castle, resurrecting from museum archives a building that once made Sheffield a nexus of power in medieval England, its lords playing ...important roles in local, national, and international affairs. Although largely demolished at the end of the English Civil War, the castle has left an enduring physical and civic legacy, and continues to exert a powerful sway over the present townscape, and future development, of Sheffield. In this volume, we rediscover the medieval castle, explore its afterlife, and discuss its legacy for the regeneration of Sheffield into the twenty-first century. The authors bring to publication for the first time all the major excavations on the site, present the first modern study of artefacts excavated in the mid-twentieth century, and situate both in the context of the published and unpublished documentary record. They also tell the stories of those responsible for re-discovering the castle, the circumstances in which they were working, their archaeological methods, and the scholarly and political influences that shaped their narratives. In setting the study within the context of urban regeneration, Sheffield Castle differs from most publications of medieval castles. This regeneration narrative is both historical, addressing the ways in which successive building campaigns have encountered the castle remains, and current, as the future of the site is under active discussion following the demolition of the market hall built on the site in the 1960s. The book explores how the former existence of the castle, and the landscape in which it sat, including its deer park, have shaped the development of the ‘Steel City’. We see that the untapped heritage of the site has considerable value for the regeneration of what may now be one of the most deprived areas of Sheffield, but was once at its social, political and cultural heart.
为探究不同地膜覆盖对南疆机采棉产量、经济效益和地膜回收的影响，本研究于2021年在新疆维吾尔自治区阿克苏地区沙雅县棉花地开展试验，以裸地（CK）为对照设置2种不同地膜覆盖处理，即高堡膜覆盖（GB）和普通PE地膜覆盖（PE），统计分析不同地膜覆盖下棉花的产量和经济效益，并对使用后的残留地膜进行回收。结果表明：高堡膜在棉花苗期（播种后20 d）能够显著提高棉田0~10 ...cm土层的土壤温度，较普通PE地膜和裸地分别提高0.78℃和2.19℃；保水率（第30天）较普通PE地膜提高2.51个百分点，具有良好的增温保墒效果。高堡膜覆盖可显著增加棉花的产量和经济效益，籽棉产量较普通PE地膜和裸地分别提高9.91%、33.13%，高堡膜覆盖和普通PE地膜覆盖的利润较裸地分别提高55.77%和27.22%。此外，高堡膜在使用前后的拉伸负荷和断裂标称应变指数整体上均高于普通PE地膜，一次性机械回收率高于80%。研究表明，高堡膜在南疆机采棉田具有较好的增温保墒效果，较普通PE地膜和裸地更有利于棉花的生长发育和产量提高，且其回收率较高，可在南疆棉田优先推广使用。This study aimed to explore the effects of different mulching films on machine-picked cotton yield, economic benefit, and mulching film recovery in southern Xinjiang. The experiment was conducted in 2021 in the cotton field of Shaya County, Aksu Prefecture, Xinjiang Uygur Autonomous Region. The bare land was used as the control to set two different mulching films, namely, high castle mulching film（GB）and common PE mulching film（PE）. The yield and economic benefits of cotton under different mulching films were statistically analyzed, and the r
The Southern Corridor of bishopric district was uncovered in early 1920s as the first Romanesque remains in the 3rd Courtyard of the Prague Castle. Based on historical context it likely originates ...from 11th − 12th century. To benchmark this estimate, radiocarbon dating of charcoals found in its mortars was performed. The results support the previous age estimate and suggest an ongoing building activity on site such as raising cascade walls at least till 14th − 16th century.
Carcinoma showing thymus‐like elements (CASTLE) is a rare tumor that commonly occurs in the thyroid gland. Extrathyroidal CASTLE is rarer, and only 11 cases of CASTLE of major salivary glands have ...been reported to date. We report the first case of amyloid deposition in parotid CASTLE. A 63‐year‐old man presented with a slowly growing mass in the left parotid region. Computed tomography revealed an approximately 28 × 23 mm mass lesion in the left parotid gland, and squamous cell carcinoma was suspected on biopsy. The patient underwent a parotidectomy with neck dissection. Morphologically, the tumor cells were squamoid and formed nests with lymphoid infiltration. Immunohistochemically, the tumor cells exhibited immunoreactivity for CD5, CD117/c‐kit and Bcl‐2, p40, and CK5 but not for p16. We diagnosed the tumor as parotid CASTLE. Amyloid deposition was also observed in the primary tumor and metastatic lymph node lesions, which were immunoreactive for cytokeratin 5. Tumor cytokeratin‐derived amyloid deposition may be one of characteristics of parotid CASTLE.
