With Memory

We address a Timoshenko system with memory in the history context and thermoelasticity of type III for heat conduction. Our main goal is to prove its uniform (exponential) stability by illustrating carefully the sensitivity of the heat and history couplings on the Timoshenko system. This investigation contrasts previous insights on the subject and promotes a new perspective with respect to the stability of the thermo-viscoelastic problem carried out, by combining the whole strength of history and thermal effects.

High Degree

Large forces and significant thermal effects are created on the rolls when rolling sheets. The higher the stability of the rolls, the less downtime during their rerolling and higher productivity. (Research purpose) The research purpose is in analyzing the ways of restoring rolls and choose the most appropriate method for restoring these parts. (Materials and methods) The article presents the analysis of the scientific and technical literature on the topic of rolling production, methods for restoring large-sized machine parts of machine-building and metallurgical industries that work in difficult conditions and are subject to a high degree of wear. Authors try to solve the problem by means of comparative and logical analysis based on theoretical and empirical methods of scientific research. (Results and discussion) The article presents two groups of methods for restoring rolled rolls: banding and surfacing the working layer of the roll. Authors have analyzed each method in terms of technology, equipment, and feasibility. The article presents the advantages and disadvantages of the methods under consideration. (Conclusions) The most acceptable way to restore parts with a high degree of wear is surfacing. It is most efficient to apply submerged surfacing using an additional hot additive. Such surfacing, despite some complication of the equipment design, allows to deposit the metal on the roll with low heat input and in most cases in one pass. Surfacing using an additional hot additive allows to increase the productivity of the process by up to 250 percent while reducing the penetration depth by 2-3 times and saving energy by up to 40 percent.

New Perspective

This book provides a radical rethinking of the relationships between teaching, researching, digging, and practicing as an archaeologist in the twenty-first century. The issues addressed here are global and are applicable wherever archaeology is taught, practiced, and researched. In short, this book is applicable to everyone from academia to cultural resource management (CRM), from heritage professional to undergraduate student. At its heart, it addresses the undervaluation of teaching, demonstrating that this affects the fundamentals of contemporary archaeological practice, and is particularly connected to the lack of diversity in disciplinary demographics. It proposes a solution which is grounded in a theoretical rethinking of our teaching, training, and practice. Drawing upon the insights from archaeology’s current material turn, and particularly Deleuze and Guattari’s concept of assemblages, this volume turns the discipline of archaeology into the subject of investigation, considering the relationships between teaching, practice, and research. It offers a new perspective which prompts a rethinking of our expectations and values with regard to teaching, training, and doing archaeology, and ultimately argues that we are all constantly becoming archaeologists.

New Perspective

Abstract This work arose from the need to broaden the therapeutic approach and offer a differentiated health intervention proposal based on the understanding that the illness process has repercussions on all integrated systems of Being. Since 2019, the Health Center for the Elderly in Blumenau (SC-Brasil), specialized multi-professional service, offering support for biopsychoenergetic transformation with the practice of Yoga and Meditation, through a holistic and comprehensive view of health. It begins with the Multidimensional Assessment of the Elderly, with a guideline in welcoming and qualified listening, which considers the subject and all subjectivity. From there, the expanded diagnosis and the Singular Therapeutic Project are built and the consultations with the team and the 'Re-Conhecer group' begin. The activity is weekly, aimed at the elderly and their family, takes place in an appropriate place and lasts two hours. Welcoming, pranayama, mantras, kriyas and meditation are made, as well as reflections on free themes. The professionals who conduct the practice are the dentist, trained in yoga, and the social worker, the welcoming process continues individually after the activity. Due to subjectivity, results are routinely collected in a qualitative way from the participants' report. There is a perception on the part of the participants, therapists and members of the multidisciplinary team that this work provides improvement in cognitive abilities, self-care, well-being, self-confidence, creativity, improved sleep, autonomy, balance, strengthening bonds, joy, vitality. Key messages This initiative builds new models of health care, transcending the traditional biomedical model, according to the operational guideline for comprehensiveness, universal access and equity. Provokes reflections and builds a new perspective of life with quality and participation of the elderly as subjects of their health.

The anoctamin (TMEM16) family of transmembrane protein consists of ten members in vertebrates, which act as Ca2+-dependent ion channels and/or Ca2+-dependent scramblases. ANO4 which is primarily expressed in the CNS and certain endocrine glands, has been associated with various neuronal disorders. Therefore, we focused our study on prioritizing missense mutations that are assumed to alter the structure and stability of ANO4 protein. We employed a wide array of evolution and structure based in silico prediction methods to identify potentially deleterious missense mutations in the ANO4 gene. Identified pathogenic mutations were then mapped to the modeled human ANO4 structure and the effects of missense mutations were studied on the atomic level using molecular dynamics simulations. Our data show that the G80A and A500T mutations significantly alter the stability of the mutant proteins, thus providing new perspective on the role of missense mutations in ANO4 gene. Results obtained in this study may help to identify disease associated mutations which affect ANO4 protein structure and function and might facilitate future functional characterization of ANO4.

Elementary Basis

Abstract Since the financial crisis of 2008 and intensified during the corona crisis, the interdependence between the stability of the financial systems and the prevailing degree of competition (DC) has been the subject of scientific and economic policy discourse on fragmented markets and „too-big-to-fail“ banks. In theory and empiricism, two fundamentally contrary causal concepts are opposed, the elementary basis of which is the precise measurement of the DC: Competition-stability- versus Fragility-Hypothesis. Based on the recent state of research, it can be shown that alternative DC-Measurements consistently show significantly different competitive conditions and in consequence the evidence for or against a stability-enhancing competitive effect seems to be predetermined by the chosen DC-Measurement.
