Adamantinoma: An up-to-date Assessment.
The special operating condition of heat recovery from a sewer pipeline makes the polymer heat exchanger particularly adapted with its equivalent thermal performance but advantages of high flexibility, modularity, and low cost.The present paper introduces a successful and general fluid-to-fluid similarity theory for heat transfer to fluids at supercritical pressure, having a high degree of universality. This work shortly follows the recent publication of a "local" successful similarity theory developed for fluids at supercritical pressures in a range of conditions in which the values of their molecular Prandtl number were quantitatively similar, extending its conclusions to the case of different molecular Prandtl numbers. The reason why this further step requested a short time to be elaborated is due to recognising that previous work by the Authors had actually already solved the related problems, though in a slightly different way, now interpreted in a more significant frame owing to a better problem understanding. The present similarity theory is based on first ideas developed more than one and a half decade ago by one of the authors, while addressing flow stability of supercritical fluids in heated channels, which encountered imrrelations for supercritical pressure fluids. It further calls for dedicated experiments needed to confirm the suitability of the present theory beyond any reasonable doubt.This article examines the community-led housing practices of two related Boyash-Roma communities in Argentina and Romania. The Argentinean case introduces the story of the Ludar in the Greater Buenos Aires Region, a Romanian-speaking sub-group of the Roma, who likely arrived here between 1880 and 1900. Throughout Argentina, most of the Ludar are involved in street vending. The second case concerns the Roma communities of the Rudari from Vâlcea County in Romania, who travel to Sweden primarily to beg. Although the cases seem unrelated, they demonstrate how close engagement with Roma and their socioeconomic mobility allows experimental comparisons of informality and urban development in various parts of world. While their mobile earning strategies are contested by authorities, they enable many to secure a feeling of belonging in a post-crisis context, characterised by rampant racism, greatly restricted welfare provision and increasingly constrained mobility. The newly emerging homes are understood as spaces of hope and dignity and the coping strategies as processes meant to unmake precarity. In this way, the article contributes to an emerging scholarship of Roma resistance, while informing broader contestations of urban marginality.As climate change advances, communities across the United States are adapting to the increased threat of wildfires, drought, heatwaves, and infectious diseases. Such disasters are expected to become more frequent and severe. Now more than ever, it is crucial to understand how these events amplify existing inequalities, and how to lessen the resulting harms. Differences in human vulnerability to disaster stem from a range of social, economic, historical, and political factors. Trichostatin A mw We argue that given their social status, undocumented Latino/a and Indigenous immigrants are particularly vulnerable to disasters and require special consideration in disaster planning. They are disproportionately affected by racial discrimination, exploitation, economic hardships, less English and Spanish proficiency, and fear of deportation in their everyday lives- their pre-disaster marginalized status. In the case of the Thomas Fire in California's Ventura and Santa Barbara counties, we show that emergency response and recovery efforts ignored their needs. Resources were directed toward privileged individuals, leaving local immigrant rights and environmental justice groups to provide essential services such as language access to emergency information in Spanish and Indigenous tongues; labor protections for farmworkers endangered in the fields; and a private disaster relief fund for undocumented immigrants ineligible for federal aid. The article concludes with preliminary participant observations from the COVID-19 pandemic response in the region, indicating how lessons from the fire have informed official actions. As governments grapple with the increasing severity of disasters, understanding the differential impacts on undocumented immigrants can help improve disaster planning to protect the most vulnerable and stigmatized populations.In this article we aim to explore the still incipient first steps of the return of extractivism to Europe, examining the geopolitical context that led to a reemergence of metal mining in rural areas. Previous emphasis on nature conservation and tourism promotion, equally fostered from European stances since the 70s on, are nowadays being confronted with a renewed focus on the strengthening of self-provision of certain raw materials. We will go through the most relevant regulations as key tools for grasping the contradiction within the new legal frameworks. Despite the urgent need to understand the changing scenario of European rural areas, the staggering reality of critical mineral extractivism, together with its environmental, ecological and social threats, is only now starting to be analyzed by social scientists.Since the end of the last century, geographers have been using the concept of touristification understood as a complex process in which various stakeholders interfere, transforming a territory through tourist activity. However, over recent years, this word has become popular in other areas with a distinct connotation, understanding touristification as a negative idea of tourism, like the massification of a destination or as a synonymous for gentrification or tourism-phobia. This situation discourages the use of the term and causes the necessity to question the usefulness of the concept, considered as too ambiguous or even empty. We argue for a correct use of the term touristification, focused on the territorial phenomenon and process it is meant to describe in a geographical approach without ideological preconceived notion, to construct knowledge from a territorial understanding of tourism in an ever-globalized world.
