This article explores the grammar-body interface by examining the intertwinement of embodied practices and turns at talk, where the sensing body permeates the ongoing syntax, in particular in activities in which the participants are engaged in talking about sensorial features while at the same time experiencing them, for instance in tasting sessions. So, the question tackled concerns how situated feelings, sensory experiences, and perceptive actions are embedded in the ongoing talk, and how they shape its emergent syntax, possibly affecting its smooth progressivity. The study shows how the choice of specific syntactic formats can be systematically related to the complex ecology of embodied actions, namely to publicly accountable ways of sensing material objects, to ways of showing and addressing an audience, and to visible ways of referring to standard documents normatively defining tasting descriptors. The syntactic formats described and their specific temporal realizations are thus deeply rooted in the local material ecology, in which they not only reproduce a normative model but reflexively express the senses with words and sensuously feel the words.

AISI 347 austenitic steel is, as an example, used in nuclear energy piping systems. Piping filled with superheated steam or cooled water is particularly exposed to high stresses, whereupon local material properties in the pipes can change significantly, especially in the case of additional corrosive influences, leading to aging of the material. In the absence of appropriate information, such local material property variations are currently covered rather blanketly by safety factors set during the design of those components. An increase in qualified information could improve the assessment of the condition of such aged components. As part of the collaborative project “Microstructure-based assessment of the maximum service life of core materials and components subjected to corrosion and fatigue (MiBaLeB)”, the short-time procedure, StrainLife, was developed and validated by several fatigue tests. With this procedure, a complete S–N curve of a material can be determined on the basis of three fatigue tests only, which reduces the effort compared to a conventional approach significantly and is thus ideal for assessing the condition of aged material, where the material is often rare, and a cost-effective answer is often very needed. The procedure described is not just limited to traditional parameters, such as stress and strain, considered in destructive testing but rather extends into parameters derived from non-destructive testing, which may allow further insight into what may be happening within a material’s microstructure. To evaluate the non-destructive quantities measured within the StrainLife procedure and to correlate them with the aging process in a material, several fatigue tests were performed on unnotched and notched specimens under cyclic loading at room and elevated temperatures, as well as under various media conditions, such as distilled water and reactor pressure vessel boiling water (BWR) conditions.

Abstract:. West Java has so many topographical area, such as highland (mountain), low land (valley) and coastal area. All of these areas have differently influenced the typology of building system, which coming from their knowledge of local material, cultures, and technology, which have been delivered from their generation.  The knowledge has been developed by times with trial and error process and become the local knowledge of this area (specific area). This paper will be elaborating the buildings (houses) on this 3 topographical area, with focusing on 3 systems of the building (house): lower, upper, and middle system. 3 parts of these building have been observed and created to propose the mapping of construction joint system. On this paper, the map of contraction system (which related to the area) has been explored on 3 traditional villages in West Java: Panjalin village at Majalengka District (located at coastal area), Cikondang village at Bandung District (located at highland area), and Mahmud Village at Bandung District (located at lowland area).Abstrak: Jawa Barat mempunyai geografis yang beragam, terdiri dari area pantai, dataran tinggi (pegunungan) dan dataran rendah. Kondisi geografis yang beragam ini, dihuni oleh masyarakat Jawa Barat yang memberikan ciri khas tersendiri dimana kehidupan tersebut berada, khususnya untuk masyarakat perkampungannya. Uniknya di Jawa Barat terdapat berbagai jenis bangunan tradisional yang mencirikan masyarakatnya, misalnya bangunan tradisional masyarakat di pantai, bangunan tradisional masyarakat di dataran rendah, dan bangunan tradisional masyarakat di dataran tinggi (pegunungan). Untuk itu, pada tulisan ini dilakukan pemetaan bangunan tradisional yang mewakili ketiga area tersebut, dengan melakukan pengamatan dan pengukuran bangunan. Pemetaan dilakukan pada 3 (tiga) lokasi yaitu kampung Panjalin–kabupaten Majalengka (yang mewakili area pantai), Kampung Cikondang–Kabupaten Bandung (yang mewakili area dataran tinggi (pegunungan), dan kampung Mahmud–Kabupaten Bandung (yang mewakili area dataran rendah). Setiap area mempunyai keunikan tersendiri, tetapi juga mempunyai persamaan, seperti konfigurasi bangunan, bentuk fisik bangunan, material, dll, tetapi ada juga perbedaan diadalam dimensi dan beberapa detail bangunan.

<p>Within present architectural discourse, there is universal concern that contemporary architectural processes efface the culture of indigenous communities, resulting in the homogenisation of architecture globally.  The imminent question therefore is; how can the assimilation of digital tools and indigenous culture be a catalyst to empower culturally embodied architecture that responds to our indigenous Māori identity and spirit, without falling into architectural homogeneity?  Working in direct conjunction with Ngai Tāmanuhi-ri Iwi (tribal group), on the poignant site, Te Kurī-a-Pāoa (Young Nicks Head), this thesis initiates dialogue to investigate the amalgamation of progressive digital fabrication techniques and the rich cultural identity and Mātauranga Māori (cultural knowledge) of Ngai Tāmanuhiri. Subsequently, a pavilion, incorporatinga locally inspired ‘whai’ (stingray) motif has been designed providing an architectural framework to facilitate design-led research. One-uku (clay), has been identified early as an indigenous material with enormous potential and led to the development of custom-built additive fabrication tools that can elevate this abundant local material for use within the architectural sphere. A secondary focus of this research is the development of computational (parametric) and analogue workflows to enable the production of architectural scale ceramic modules.  Ultimately, this thesis argues that when computational design skills are ulilised alongside indigenous knowledge, digitally produced artefacts are capable of becoming meaningful for all.</p>

Welding is a joining process that leads to considerable change in the local material and the formation of welding residual stresses (RS). Welding residual stresses can be compressive (beneficial for the fatigue life) or tensile (harmful for the fatigue life). In this chapter, a probabilistic analysis of residual stresses distribution posterior to welding processes is carried out. Several researchers stated that the type of the introduced stresses either compressive or tensile depends on several factors. Some of these factors are listed in this chapter. Welding of mega-structures is carried out in the workshops, then a cutting process takes place to construct the exact size of the structural components. This cutting process has a significant effect on the weld residual stresses re-distribution. A study of the re-distribution of the weld residual stress after cutting was performed. It was found that independent of the weld seam length, the residual stresses re-distributed up to 60 % of the weld seam length.

Introdução: A conservação tem como um dos seus principais objetivos a manutenção da biodiversidade. As métricas para medir a biodiversidade em uma determinada área, dependem da interação de vários fatores, como por exemplo a relação de dados bióticos (como grupos taxonômicos) com dados abióticos (informações sobre o clima ou vegetação), sendo possível mensurar os efeitos do ambiente nos organismos. Objetivo: Sendo assim, a proposta deste trabalho é fazer um levantamento faunístico focado na ordem Hemiptera, a fim de poder contribuir para futuros trabalhos de monitoramento ambiental no local. Material e Métodos: As coletas foram realizadas no interior e entorno do Parque Nacional da Chapada Diamantina (PNCD) que está situado no centro do Estado da Bahia, sendo o PNCD uma área de proteção integral. Foram amostrados 20 pontos, distribuídos em dois municípios, Palmeiras e Lençóis. As amostras foram obtidas com auxílio de uma rede entomológica do tipo D e fixadas em álcool 70%, posteriormente levadas para o Laboratório de Organismos Aquáticos na Universidade Estadual de Santa Cruz – Ilhéus/Ba. As amostras foram triadas em caixa luminosa, e identificadas em microscópio estereoscópio. As identificações ocorreram a nível de gênero com chave específica para a ordem Hemiptera. Resultados: Foram identificados 627 indivíduos pertencentes a 16 gêneros distribuídos em 11 famílias, Belostomatidae, Corixidae, Gerridae, Hebridae, Helotrephidae, Mesoveliidae, Naucoridae, Nepidae, Notonectidae, Veliidae e Saldidae. Dentro e fora do PNCD, foram coletados, 389 e 238 indivíduos, respectivamente. Fora do PNCD houve a presença de 17 gêneros, enquanto dentro houve 16, onde fora obteve maior riqueza. O estado da Bahia, possui registro de 124 gêneros de Heteroptera. Dentre os gêneros coletados, Ambrysus., Cataractocoris, Ctenipocoris, Enitharoides, Lipogomphus, Martarega, Mesoveloidea, Microvelia, Monogobia, Neotrephes, Notonecta, Ranatra, Rhagovelia e gên 1. (Saldidae) são novos registros o estado. Trabalhos de cunho taxonômico como levantamentos faunísticos, contribuem para o conhecimento da diversidade da fauna do PNCD e consequentemente do estado da Bahia. Conclusão: Entender a distribuição das espécies de insetos aquáticos unidos à dados abióticos, permite que um aprimoramento nos índices de qualidade de água, uma vez que a biologia das espécies ainda é um mistério no estudo dos insetos aquáticos.

A decentralist history of Lyon’s musical life (Reuchsel, 1903) offers a springboard for rethinking the themes of decentralization, regionalism and deconcentration as they played out in France’s urban centers across the century from the 1830s to the 1930s. Comparison of decentralist and regionalist practice within the visual arts sets in relief the complex problems musicians experienced—from the ephemerality of composer groups to the state’s inability to showcase regional student compositions. Opera presented more opportunity to showcase regional difference, but the spectre of “colonization” remained, and local demands for “authentic” use of local material existed in tension with the vague atmospherics necessary for Parisian acceptance. The Vichy régime’s centralist appropriation of regionalism tainted the musical work of half a century as ruralist reaction of the extreme Right. New paradigms of thought stemming from ecomusicology suggest ways beyond the impasse of Left–Right politics that have dominated recent study.

Vascular calcification, once considered a degenerative, end-stage, and inevitable condition, is now recognized as a complex process regulated in a manner similar to skeletal bone at the molecular and cellular levels. Since the initial discovery of bone morphogenetic protein in calcified human atherosclerotic lesions, decades of research have now led to the recognition that the regulatory mechanisms and the biomolecules that control cardiovascular calcification overlap with those controlling skeletal mineralization. In this review, we focus on key biomolecules driving the ectopic calcification in the circulation and their regulation by metabolic, hormonal, and inflammatory stimuli. Although calcium deposits in the vessel wall introduce rupture stress at their edges facing applied tensile stress, they simultaneously reduce rupture stress at the orthogonal edges, leaving the net risk of plaque rupture and consequent cardiac events depending on local material strength. A clinically important consequence of the shared mechanisms between the vascular and bone tissues is that therapeutic agents designed to inhibit vascular calcification may adversely affect skeletal mineralization and vice versa. Thus, it is essential to consider both systems when developing therapeutic strategies.
