Published: October 2022

Utilizando-se a metodologia geoestatística de krigeagem ordinária realizou-se a estimativa dos valores de resistência e caracterização textura! de um solo residual de arenito, com o intuito de obter mapas em diversas profundidades das resistências unitárias de ponta e lateral conforme método proposto por Aoki e Velloso. O mapeamento geoestatístico foi realizado com base em 241 relatórios de sondagens SPT da área estudada obtendo-se como produto final mapas das resistências unitárias de ponta e lateral a diversas profundidades.

Os resultados gerais obtidos mostram que em 82,3% da área estudada (40,5 km 2) ocorrem maciços de solos apresentando resistências unitárias de ponta inferiores a 15,0 MPa e 86,2% (42,4 km2) com resistências unitárias lateral inferiores a 0,4 MPa, em média, até 8,5 metros de profundidade. Analisando os mapas produzidos, verificou-se uma distribuição espacial dos maciços de solos mais favorável à implantação de fundações profundas em profundidades superiores a 11,0 metros. Espera-se com esse trabalho indicar, através das estimativas probabilísticas das resistências de ponta e lateral dos maciços de solos, áreas do meio físico urbano que atendam às condições mínimas de projeto de fundações, que possibilitem a previsão da capacidade de carga última de fundações profundas, principalmente como instrumento preliminar de orientação da variabilidade geométrica da superfície de apoio dessas fundações.

Participatory co-design of science communication strategies for public engagement in the US and Ecuador around health behaviour change
Authors: Vásquez-Guevara Denisse , Weiss David , McIntosh White Judith
Published: October 2022

Science communication research and practice currently promote strategies oriented towards creating audience engagement around scientific content. Consequently, science communication needs to continually explore new methodologies that enable audiences’ participation in order to meet their interests and needs. The present study combines qualitative and participatory action research (PAR) methods guided by decolonial epistemologies to develop a co-designed project with public health, nutrition and sports science researchers to recruit young audiences from Albuquerque, New Mexico, USA, and from Cuenca, Ecuador. The main goal of this study was to create strategies to motivate young audiences’ engagement and interest in adopting healthy habits. This article focuses on the study’s research design in order to provide guidelines and procedural recommendations for facilitating a co-design approach for developing science communication initiatives targeting children and teenagers in Ecuador and the United States. As we demonstrate, the PAR approach for co-design leads to useful outcomes: (1) the incorporation of decolonial theory guidelines in participatory research; and (2) the development of science communication strategies that combine online and offline activities to put in dialogue scientists and their audiences, ultimately resulting in mutual learning, thus allowing scholars and practitioners to explore in practical terms how to co-design improved strategies.

Authors: Anzilago Marcielle , Daciê Franciele do Prado , Sanches Simone Leticia Raimundini
Published: October 2022

O estudo analisa a influência dos traços de personalidade na motivação para a carreira profissional a partir da mediação do senso de coerência e da autoestima em acadêmicos de pós-graduação stricto sensu em ciências contábeis no Brasil. O instrumento de pesquisa foi composto por um questionário com escala tipo Likert de 7 pontos. Obteve-se 208 respostas válidas, analisadas pela técnica de modelagem de equações estruturais. Os resultados apontam que os traços de personalidade influenciam, de forma direta, na motivação dos acadêmicos na escolha de seguir ou não a carreira acadêmica. A variável autoestima mediou a relação entre os traços de personalidade e sua motivação para carreira profissional. Concluiu-se que os traços de personalidade e a motivação para a carreira são influenciados pelo senso de coerência e autoestima. Além das contribuições teóricas, que se refere a lacuna existente da análise das três variáveis conjuntamente, o estudo permite evidenciar dois pontos para os membros dos programas de pós-graduação; que os traços de personalidade dos alunos influenciam na sua decisão de seguir a carreira profissional acadêmica, e; as situações vivenciadas por esses acadêmicos durante a pós-graduação (estresses, cobranças, estímulos e reconhecimentos) podem ter efeitos na sua motivação e impactar diretamente no seu desempenho stricto sensu e na sua decisão de seguir ou não na área acadêmica.
An exploration of individual, job, and organizational characteristics associated with district research leaders' knowledge brokering work
Authors: Shewchuk Samantha Jo , Farley-Ripple Elizabeth
Published: October 2022

The role of district research leaders (DRLs) in central offices has emerged as a strategy for improving the creation, flow, and use of research knowledge in decision-making. However, there is limited information about the responsibilities, opportunities, and challenges inherent in these roles. This exploratory qualitative study features document analysis to examine the individual backgrounds, job demands, and organizational contexts of DRLs. The result of this study suggest that multiple pathways to the DRL role exist, but few include formal training in knowledge brokering. Further findings suggest that DRL jobs are complex and entail diverse tasks, but share a focus on research leadership and coordination, identifying and obtaining relevant research information, and facilitating evidence-informed change. Moreover, organizational contexts varied in supportiveness for knowledge brokering work. Overall, there was limited evidence of alignment across individual, job, and organizational characteristics, signaling an opportunity to better define and support those in DRL roles.

Energietransition im Rheinischen Revier – Implikationen der Projektförderung für eine grüne Pfadentwicklung
Authors: Aring Mascha , Breul Moritz , Revilla Diez Javier
Published: October 2022

Abstract  
With the phase-out of lignite, the Rhenish mining area is at the beginning of a transformation process that will take decades. Structural funds of almost 15 billion euros are to be allocated as project funding until 2038. The basis for this is the economic and structural programme and a regional consensus with representatives of the region. The aim of this paper is to investigate to what extent the funding project selection helps to establish green development paths and move closer to the ambitious goal of a sustainable model region for energy supply and production. For this purpose, the characteristics of 22 submitted projects in the “Zukunftsfeld” energy and industry are analysed with regard to a typology of green paths. With the help of nine interviews, framework conditions (design of the funding process and resource endowment of the actors) that influence green path development processes in the Rhenish Revier could be identified. Path renewal processes of the regional industry as well as path creation dynamics especially in the hydrogen sector can be found. Overall, the project selection is determined by a high proportion of knowledge institutions, whose participation is favoured by the framework conditions. The participation of small and medium sized enterprises and municipalities, on the other hand, is hampered by the framework conditions, which means that existing regional potentials are not utilized optimally and the transformation process as a whole can be compromised.
Selbstständige Beschäftigung von geflüchteten Neuzugewanderten in ländlichen Räumen am Beispiel von Lebensmittelgeschäften: Aspirationen, Praktiken und ihr Beitrag für die lokale Versorgung
Authors: Kordel Stefan , Sauerbrey Dominic , Weidinger Tobias
Published: October 2022

The population structure and life in rural areas have become more diverse in recent years due to the arrival and stay of refugees. The participation of the newcomers in the labour market is relevant on the one hand from the point of view of integration policy and for the regional economy, and on the other hand it fulfils various functions for them. However, little attention has been paid to the (potential) self-employment of newly arrived refugees in Germany. Using the example of the founding of grocery stores in rural areas of Germany, the aspirations of refugees on the labour market, the founding and business practices of operators and the perspectives of customers were examined from multiple perspectives. The qualitative interviews conducted with (potentially) self-employed newly arrived refugees and (semi-)standardized surveys of customers form the data basis for this paper. It is conceptually inspired by the state of research on migrant’s integration to work and immigrant entrepreneurship as well as the subform refugee entrepreneurship. Results show a variety of meanings of employment and a distinct desire for self-employment. Moreover, structural and individual obstacles could be identified in the foundation phase, while co-ethnic employment is considered crucial for the operation of a store.
The Idea of Geospatial-Gender-Based Data Infrastructure for Protecting Women Living in Post Covid-19 Created Global Village
Authors: Parihar Seema Mehra , Bannerjee Tapati , Sonkar S. , Ali M. B.
Published: October 2022

Abstract. The COVID-19 pandemic has altered the lived realities of people across the globe.  Though science has made a breakthrough with a vaccine, the virus has already taken the lives of lakhs of people, rendered millions jobless, and taken an emotional toll on the billions world over.  Geovisualization with the gendered lens made a world look like a global village with similar pains across regions, class, sexuality, race, and caste.  This paper suggests a case for evolving Geospatial-gender-based data Infrastructure (GGBDI)  for empowering women. This paper is not only about access to healthcare all over the world but about generating data for empowering women holistically.  It also aims to find how gendered the various governments' responses, different institutions, organizations, and families had been. Suggested Geo-Spatial Informatics can assign application developers and users a framework to formulate a comprehensive model on integrating concerns around gender. Paper recognizes the need for putting 300 gender-disaggregated data in one place. The eight thematic GI layers of geospatial data include demography, health and women, economy and livelihood, women violence and safety, education and skill-based opportunities, indigenous communities and women, and gender mainstreaming and budgeting.  For each layer and sub-sub layers, using various algorithms, separate GI indexes have been calculated too.  Further, around COVID-designed polygons -clusters, buffers, containment zones, the story maps are created with Arc GIS software with the potential of replication.   Designed Geospatial informatics aims to be used by planners, policymakers, field functionaries, academicians, and civil societies to collectively and help mainstream gender concerns across policy plans and programs.

Authors: Zhang Jiali , Zhao Guangpu , Li Na , Gao Xue , Zhang Ying
Published: October 2022

Two-dimensional electromagnetohydrodynamic behavior of nanofluids through rectangular microchannels is investigated. The combined effects of time-periodic pressure gradients and magnetic fields in terms of the Hall effects on nanofluid flow are considered. Under the Debye–Hückel linearization approximation, the semi-analytic solution of the velocity field is derived by Green’s function method. Furthermore, the semi-analytic solutions of electrokinetic energy conversion (EKEC) efficiency and the streaming potential of nanofluids through the rectangular microchannels are obtained. The variations of the velocity, streaming potential, and EKEC efficiency with the electric double layer thickness K, Hartmann number Ha, Hall parameter m, and dimensionless frequency Ω are shown and briefly discussed.

Unregulated LDL cholesterol uptake is detrimental to breast cancer cells
Authors: Scully Tiffany , Ettela Abora , Kase Nathan , LeRoith Derek , Gallagher Emily Jane
Published: October 2022

Tumor uptake of exogenous cholesterol has been associated with the proliferation of various cancers. Previously, we and others have shown that hypercholesterolemia promotes tumor growth and silencing of the LDL receptor (LDLR) in high LDLR-expressing tumors reduces growth. To advance understanding of how LDL uptake promotes tumor growth, LDLR expression was amplified in breast cancer cell lines with endogenously low LDLR expression. Murine (Mvt1) and human (MDA-MB-468) breast cancer cell lines were transduced to overexpress human LDLR (LDLROE). Successful transduction was confirmed by RNA and protein analysis. Fluorescence-labeled LDL uptake was increased in both Mvt1 and MDA-MD-468 LDLROE cells. The expression of the cholesterol-metabolizing genes, ABCA1 and ABCG1, was increased, while HMGCR was decreased in the MDA-MB-468 LDLROE cells. In contrast, Mvt1 LDLROE cells showed no differences in Abca1 and Abcg1 expression and increased Hmgcr expression. Using a Seahorse analyzer, Mvt1 LDLROE cells showed increased respiration (ATP-linked and maximal) relative to controls, while no statistically significant changes in respiration in MDA-MB-468 LDLROE cells were observed. Growth of LDLROE cells was reduced in culture and in hypercholesterolemic mice by two-fold. However, the expression of proliferation-associated markers (Ki67, PCNA and BrdU-label incorporation) was not decreased in the Mvt1 LDLROE tumors and cells. Caspase-3 cleavage, which is associated with apoptosis, was increased in both the Mvt1 and MDA-MB-468 LDLROE cells relative to controls, with the Mvt1 LDLROE cells also showing decreased phosphorylation of p44/42MAPK. Taken together, our work suggests that while additional LDL can promote tumor growth, unregulated and prolonged LDL uptake is detrimental.

The role of androgens in vascular reactivity is controversial, particularly regarding their age-related actions. The objective of this study was to conduct a temporal evaluation of the vascular reactivity of resistance arteries of young male rats, as well as to understand how male sex hormones can influence the vascular function of these animals. Endothelium-mediated relaxation was characterized in third-order mesenteric arteries of 10-, 12-, 16-, and 18w (week-old) male rats. Concentration–response curves to acetylcholine (ACh, 0.1 nmol/L–10 µmol/L) were constructed in arteries previously contracted with phenylephrine (PE, 3 µmol/L), before and after the use of nitric oxide synthase or cyclooxygenase inhibitors. PE concentration–response curves (1 nmol/L–100 μmol/L) were also built. The levels of vascular nitric oxide, superoxide anion, and hydrogen peroxide were assessed and histomorphometry analysis was performed. The 18w group had impaired endothelium-dependent relaxation. All groups showed prostanoid-independent and nitric oxide-dependent vasodilatory response, although this dependence seems to be smaller in the 18w group. The 18w group had the lowest nitric oxide and hydrogen peroxide production, in addition to the highest superoxide anion levels. Besides functional impairment, 18w animals showed morphological differences in third-order mesenteric arteries compared with the other groups. Our data show that time-dependent exposure to male sex hormones appears to play an important role in the development of vascular changes that can lead to impaired vascular reactivity in mesenteric arteries, which could be related to the onset of age-related cardiovascular changes in males.
OXIDATIVE STRESS AND REPRODUCTIVE FUNCTION: Oxidative stress and the long-term storage of horse spermatozoa
Authors: Peña Fernando J , Gibb Zamira
Published: October 2022

In brief

The growing understanding of the mechanisms regulating redox homeostasis in the stallion spermatozoa, together with its interactions with energetic metabolism, is providing new clues applicable to the improvement of sperm conservation in horses. Based on this knowledge, new extenders, adapted to the biology of the stallion spermatozoa, are expected to be developed in the near future.

The preservation of semen either by refrigeration or cryopreservation is a principal component of most animal breeding industries. Although this procedure has been successful in many species, in others, substantial limitations persist. In the last decade, mechanistic studies have shed light on the molecular changes behind the damage that spermatozoa experience during preservation. Most of this damage is oxidative, and thus in this review, we aim to provide an updated overview of recent discoveries about how stallion spermatozoa maintain redox homeostasis, and how the current procedures of sperm preservation disrupt redox regulation and cause sperm damage which affects viability, functionality, fertility and potentially the health of the offspring. We are optimistic that this review will promote new ideas for further research to improve sperm preservation technologies, promoting translational research with a wide scope for applicability not only in horses but also in other animal species and humans.

Dynamics of the weed community during pineapple growth in the Brazilian semi-arid region
Authors: Prudêncio dos Santos João Rafael , Maia Victor Martins , Soares da Silva Bruno , Demicheli Pedro Mendes , Aspiazú Ignacio , Concenço Germani
Published: October 2022

The pineapple belongs to the family Bromeliaceae and is a slow-growing succulent monocot with a reduced superficial root system. For this reason, the interference of weeds in competition with this crop can cause significant losses to the production. One of the bases to elaborate a control strategy is the knowledge of the diversity of weeds that occur in the cultivated areas. The objective of this study was to identify the weed community during pineapple growth in a semi-arid climate region of Brazil. Weeds were collected 60, 120, 180, 240, 300, and 360 days after planting (DAP) the pineapple. These collections were made in three different plots every two months until floral induction, composed of three pineapple cultivars. The weed community found in the irrigated pineapple field, in semi-arid climate conditions, was mostly composed by species belonging to the families Amaranthaceae, Asteraceae, Convolvulaceae, Fabaceae, Malvaceae, and Poaceae. The highest diversity of weed species was found at 60 DAP. The species Ipomoea acuminata was present throughout the development of the pineapple and showed the highest importance value index in most of the periods evaluated during the pineapple growth.

Glyphosate, glufosinate, and atrazine do not affect the growth and development of glyphosate and glufosinate-tolerant (RR2/LL) maize; however, the results are less consolidated for these herbicides applied in mixtures. The aim of the present study was to evaluate the effects of post-emergent application of glyphosate, glufosinate, and atrazine, alone and in mixtures, on the growth and development of the RR2/LL maize. The treatments consisted of the application of glyphosate (1080 g of acid equivalent [ae] ha-1), glufosinate (500 g of active ingredient [ai] ha-1), atrazine (2000 g [ai] ha-1), glyphosate + glufosinate, glyphosate + atrazine, glufosinate + atrazine, glyphosate + glufosinate + atrazine, and the control (without application). The experiment was carried out in two locations under greenhouse conditions with different maize hybrids. Crop injury and variables of the agronomic performance (height, stem diameter, chlorophyll indexes, fresh and dry weight of shoot, root dry weight, and total dry weight) were evaluated. Herbicides applied alone or in binary mixtures did not cause major damage. However, the application of the three associated herbicides in some situations might result in detrimental effects on the development of the RR2/LL maize.
Fusarium species that cause corn stalk rot in the Ubaté valley of Cundinamarca, Colombia
Authors: Maldonado Archila Germán Yesid , Ligarreto-Moreno Gustavo , Gómez-Caro Sandra
Published: October 2022

In recent years, corn (Zea mays L.) crops in the Colombian cold tropics located in the Ubaté valley in Cundinamarca have been affected by stalk rot with incidences up to 40%. Despite the importance of this disease, accurate diagnosis has not been conducted. The objectives of the study were to determine the causal agents of corn lodging associated with stalk rot in this corn-producing region and describe the symptoms of the disease. Two plots with stalk rot reported in the municipality of Simijaca in July 2016 were sown with the regional varieties Simijaca and Sogamoso. Plants were randomly inspected on a monthly basis for describing disease symptoms and isolating the pathogen. The Fusarium species isolated were morphologically and molecularly identified and pathogenicity tests were conducted. The disease was detected at early plant developmental stages with the combination of chlorosis, leaf anthocyanosis, and dwarfism as the main symptoms in the two corn varieties evaluated. Crown and node necrosis in longitudinal sections of the stalk and purple colorations in the crown, nodes and internodes of plants were observed 90 d after sowing. Finally, lodging occurred at any phenological stage of the crop. Fusarium spp. were isolated in all stages of plant development. Fusarium species were identified as F. graminearum in the Fusarium graminearum species complex and F. subglutinans in the Fusarium fujikuroi species complex, which have cold-climate production zones as their ecological niche. Pathogenicity tests confirmed F. graminearum and F. subglutinans as the causal agents of stalk rot in the regional corn variety Simijaca in the Ubate valley in Cundinamarca.

Diversos estudos sobre sociobiodiversidade e PFNM têm sido realizados, principalmente sobre inclusão produtiva e formação de mercados para valoração econômica da floresta em pé, o que invisibiliza a importância desses produtos para a organização social e econômica das comunidades e populações tradicionais, principalmente no que se refere à alimentação. Diante disso, o objetivo deste trabalho foi analisar o consumo alimentar das famílias em uma comunidade ribeirinha amazônica, a fim de identificar a presença dos produtos da sociobiodiversidade nos hábitos alimentares locais. A coleta de dados foi feita por meio de observação direta e de entrevistas realizadas com 15% das famílias moradoras da comunidade Surucuá, na Reserva Extrativista Tapajós–Arapiuns. Foram contabilizadas 63 espécies da biodiversidade local que fazem parte da alimentação das famílias, das quais 24 não são reconhecidas na lista brasileira oficial de produtos da sociobiodiversidade. Mediante estudos de viabilidade, essas espécies podem ser incluídas na referida lista e, assim, subsidiar a formação de novas cadeias produtivas. Além disso, os resultados mostram que a relação das famílias com a floresta e com os quintais evidencia a sociobiodiversidade como elemento do sistema socioecológico e o extrativismo vegetal como atividade significativa na configuração da comunidade e na reprodução social.
O manejo ambiental em Nova Aliança, Alto Solimões: memórias do passado e reflexos no presente
Authors: Lopes Marcileia Couteiro , Noda Hiroshi
Published: October 2022

As sociedades humanas da Amazônia foram ao longo do tempo sendo transformadas pelo sistema ambiental em que vivem e de forma recursiva foram transformando o sistema ambiental, uma simbiose que demonstra memórias passadas e reflexos no presente. Este artigo tem por objetivo descrever a busca identitária dos indígenas em Nova Aliança, via fundação de sua comunidade, relações sociais, crenças e topofilia manifestada no manejo do sistema ambiental. Assim fazemos uma triangulação de análise entre identidade, manejo e topofilia. A partir do Estudo de Caso Único foi possibilitado a adoção dos preceitos da Etnobiologia e da Etnoecologia, para emersão de dados primários e secundários, por meio da aplicação de técnicas de pesquisa participativa, os quais compuseram uma abordagem quali-quantitativa dos dados. O caso escolhido foi a comunidade Nova Aliança, localizada no município de Benjamin Constant, região do Alto Rio Solimões, Amazonas, Brasil, na qual os moradores se autoidentificam como indígenas da etnia Cocama. Os levantamentos e as análises dos dados coletados em campo evidenciaram que em Nova Aliança, desde sua origem, princípios como religiosidade, topofilia, relações de parentesco, cultura e reciprocidade, norteiam seu modo de viver e manejar o sistema ambiental, refletindo em como constroem, transformam, significam e (re)significam relações sociais e as suas ações ao longo do tempo, frente as emergências que surgem.
Ayahuasca comes to the city!
Authors: Weiskopf Jimmy
Published: October 2022

Ayahuasca has spread from indigenous Amazonia to the industrialized world, in the form of ceremonies catering to Westerners, a corpus of academic studies and personal accounts and depictions of it in novels and films. Considering that its original users were zealous about revealing it to outsiders and their traditional cultures were being eroded by the mainstream’s society’s colonization, its very survival is a paradox, in that the native ayahuasqueros have been both the victims and beneficiaries of its globalization. Thus, this essay traces the dissemination of yajé (the Colombian name for ayahuasca) from the standpoint of the author, an early participant in the rituals which began to be held in Bogotá by a handful of taitas (indigenous healers) in the early 1990’s, whose number has since increased to at least fifty who regularly work in that and other Colombian cities. Then a set of closely related aspects are discuted:  the disruptive socio-economic changes in the heartlands of yajé, like the Putumayo (especially the cocaine boom), which have impelled the traditional healers to seek new “markets” for their medicine; other focal points for its expansion; the clash between different healers about the ethics of providing their services to White men; the parallel establishment of ayahuasca “churches” in Brazil (with branches in Europe) which owe little to the indigenous tradition; the development of an “ayahuasca tourism” in Peru; and the legal status of the medicine in North America and Western Europe.
Proceso de Comunidades Negras (pcn) en Colombia: naturaleza socioterritorial, concepciones y prácticas de participación
Authors: Areiza Lozano Eduardo
Published: October 2022

En este artículo se sustenta la naturaleza socioterritorial del Proceso de Comunidades Negras (pcn) en Colombia desde su forma de organización territorializada en palenques regionales y su objetivo medular de lucha, reivindicación y defensa de los territorios y la territorialidad ancestral de estas comunidades; así como también, las concepciones y prácticas de participación, que los activistas de esta colectividad desarrollan en defensa de los derechos étnico-territoriales reconocidos en la Ley 70 de 1993.
“Tinanica”, un enredo multiespecie: apuntes sobre el cuidado y la defensa de un humedal en el sur de Bogotá
Authors: Vargas Aldana Claudia María
Published: October 2022

Este artículo aborda, desde la interfaz entre la etnografía multiespecie, el feminismo y los estudios sociales de la ciencia, los enredos multiespecie que emergen de las prácticas de cuidado del humedal de Tibanica en la localidad de Bosa en Bogotá. Es decir, retoma los entramados relacionales entre distintas especies que contribuyen al sostenimiento de este ecosistema. Así pues afirma, a través de descripciones etnográficas sobre “Tinanica” y el proceso de germinar en el agua, que estos enredos que emergen del cuidado permiten la apropiación del territorio y la defensa del humedal por parte de Tina Fresneda y del Colectivo Ambiental Germinamos en Tibanica.
Sociedad/comunidad y naturaleza. Una propuesta de análisis desde la memoria sociohídrica de los comuneros y ejidatarios del río Amatzinac en Tetela del Volcán, México
Authors: Yañez Reyes Diana Laura , Galicia Hernández Esther
Published: October 2022

Las formas de vida, convivencias e interacciones que se gestaron en los inicios de la organización ejidal y comunal de los campesinos de la parte alta del río Amatzinac reflejaron los vínculos matriciales entre comunidades y naturaleza, nexos esenciales derivados de la condición humana. En este contexto temporal y espacial se estableció una íntima relación de ejidatarios y comuneros con los ecoambientes y el agua del río, formas de apropiación y representación que definieron su territorialidad y tejieron en el tiempo lazos objetivos y subjetivos que dejaron huellas profundas en la memoria individual y colectiva, improntas que actualmente parecen desvanecerse.
Einblick in die Finanzwirtschaft zur Zeit Leopolds I.
Authors: Körbl Hansdieter
Published: October 2022

In dem hier vorliegenden Band der Reihe Fontes Rerum Austriacarum II werden drei umfangreiche und mit einem detaillierten Zahlenmaterial versehene Berichte von Hofkammerräten an den Kaiser vorgestellt. Sie stehen im Zusammenhang mit Fragen des Kaisers an die Hofkammer im Vorfeld des Prozesses gegen den Hofkammerpräsidenten Georg Ludwig Sinzendorf im Jahr 1680. Die Edition ist, abgesehen von den darin enthaltenen Angaben finanzieller Natur, vor allem auch deshalb interessant, weil sich damit ein Überblick zu den Strukturen der Behörden und ihrem Wirken zur Zeit Kaiser Leopolds I. erschließt. In mancher Hinsicht könnte man sogar von subjektiv-individuellen Landesbeschreibungen der drei Mitglieder der Hofkammer sprechen.
Recent advances on bonding mechanism in cold spray process: A review of single-particle impact methods
Authors: Adaan-Nyiak Moses A. , Tiamiyu Ahmed A.
Published: October 2022

Cold spray (CS) processing is a layer-by-layer solid-state deposition process in which particles at a temperature below their melting point are launched to sufficiently high velocities to adhere to a substrate (and previously deposited particles), forming coatings/parts. Despite being in existence for over four decades, particle bonding mechanisms in the CS process are unclear due to the complex particle–particle/carrier gas interactions that obscure assessment. This review evaluates recent findings from single-particle impact approaches that circumvent these complexities and further provide new insights on bonding mechanisms. Theories on the evolution of oxide layer breakup and delamination, adiabatic shear instability, jetting, melting, and interface solid-state amorphization that contributes to bonding are assessed and carefully reviewed. Although there is a unified condition in which bonding sets on, this study shows that no singular theory explains bonding mechanism. Rather, dominant mechanism is a function of the prevailing barriers unique to each impact scenario.
