From the point of view of environmental protection, the development of vehicles and their drives is determined in the future by the constant tightening of exhaust gas requirements. In addition, measures to reduce fuel consumption and CO2 emissions are increasingly influencing the concept of vehicle and drive optimization. Since most of the world's energy consumption is taken by transport, mainly cars, manufacturers are often faced with the need to develop and implement new, increasingly energy efficient and environmentally friendly energy methods - for example, the use of unconventional fuels, including: alcohol fuels (ethanol and methanol), biodiesel, Fischer's fluid -Tropsch, hydrogen fuel. So, the long-term guaranteed supply of transport energy, together with sound fuel management, ensures the medium and long-term diversification of energy for its production, especially, including alternative and renewable energy. Much has happened over the past decade, although policy goals remain unchanged for many countries improving energy security and limiting greenhouse gas emissions may be more important than ever. And, unprecedentedly, energy use in transportation is at the heart of these issues. New methods are needed to free transport from its persistent dependence on oil and take a new path. But technology has made interesting progress, and this progress will continue in the coming years, creating new opportunities to achieve these goals. Unsurprisingly, interest in biofuels and their production has skyrocketed over the past decade. Global production of total ethanol doubled between 1990 and 2021. In some regions, especially in Europe, the use of biofuels for diesel engines has also increased significantly in recent years. Perhaps most importantly, countries around the world are now seriously considering increasing the production and use of biofuels, and many countries have formulated policies to ensure this growth.

SummaryTo survey major developments and trends in the field of Bioinformatics in 2010 and their relationships to those of previous years, with emphasis on long-term trends, on best practices, on quality of the science of informatics, and on quality of science as a function of informatics.A critical review of articles in the literature of Bioinformatics over the past year.Our main results suggest that Bioinformatics continues to be a major catalyst for progress in Biology and Translational Medicine, as a consequence of new assaying technologies, most predominantly Next Generation Sequencing, which are changing the landscape of modern biological and medical research. These assays critically depend on bioinformatics and have led to quick growth of corresponding informatics methods development. Clinical-grade molecular signatures are proliferating at a rapid rate. However, a highly publicized incident at a prominent university showed that deficiencies in informatics methods can lead to catastrophic consequences for important scientific projects. Developing evidence-driven protocols and best practices is greatly needed given how serious are the implications for the quality of translational and basic science.Several exciting new methods have appeared over the past 18 months, that open new roads for progress in bioinformatics methods and their impact in biomedicine. At the same time, the range of open problems of great significance is extensive, ensuring the vitality of the field for many years to come.

AbstractThe point of view taken here is that systems analysis is a kind of learning process, not data gathering, not decision making, but the production and effective communication of arguments relevant in a particular context. This idea, that the intended application of the result of an assessment has consequences for methodological choices, is beginning to spread in the LCA research community. One problem is that standard LCA methodology is developed to answer questions about environmental impacts of the current production and use of one unit of a product or minor product or process changes. When this methodology, unchanged, is used to provide answers to questions about strategic technology choice, i.e. not decisions that aim at improving a process within an existing technological environment, but with the long-term goal of changing large-scale technological systems, the result could be of little value or misleading. In many cases, LCAs produce more noise than knowledge. This observation seems to be of particular importance for LCAs of energy technologies and for how energy use is treated in all kinds of LCAs. Here, it is suggested that a better understanding of some critical methodological issues related to time, universality, cause-effect relationships, technical maturity and system innovation, could result in better studies that reveal fundamental environmental issues related to the objects of study and reduce the noise from irrelevant information. Examples are given from the technology fields of solar cells, fuel cells, batteries, renewable transport fuels and carbon nanoparticles.

Ivan Petrović (1973) has been working in the fields of photography and art for twenty years as a researcher, creator and collector. Since 1997, he has been creating and publishing photographic projects that reflect the spirit of space and time in which they are created, while in his works he uses both documentary approaches as well as research principles. In 2011, together with photographer Mihail Vasiljević, he founded a para-institution, the Centre for Photography (CEF). Despite lacking its own premises, infrastructure or funds for performing its activities, the institution deals with the search, preservation, collection and analysis of local photographic materials from recent history. In the past ten years, Petrović also moved his artistic practice beyond mere artistic expression, since he addresses the phenomena of photography from an analytical-theoretical point of view. His interest lies in the nature of the photographic image and its role in society and historiography. In this spirit, long-term projects such as Documents (1997–2008), Images (2002–), Portfolio Belgrade (2015–) and the latest film production were created. The interview with Ivan Petrović took place on 1 September 2017 in Belgrade. The main themes were the role of photography in the dominant history, the boundary between one’s own practice and archival work, photography as an art and the likes.

Abstract The past thirty years has brought an important change into the scholarship of the period of the last Habsburgs on the Spanish throne. Named after the book by Christopher Storrs, the long-term paradigm of the decline of the Spanish monarchy in the last half of the seventeenth century has been reestablished, however, the research of the relationships between the Spanish Habsburgs and Central Europe in the last quarter of the seventeenth century has yet to be to be considered. This study presents a more complex perception of the coup led by Juan José of Austria in the year 1677 and discovers an important perception of the situation from the point of view of the Emperor Leopold I and the Elector of Brandenburg Frederick William. The new Spanish government, as well, enacted shifts in their politics which could endanger their positions, however both accepted the new situation differently.

One of the most exciting recent developments in archaeology and history has been the adoption of new perspectives which see human societies in the past--as in the present--as made up of networks of interlinked individuals. This view of people as always connected through physical and conceptual networks along which resources, information, and disease flow, requires archaeologists and historians to use new methods to understand how these networks form, function, and change over time. The Connected Past provides a constructive methodological and theoretical critique of the growth in research applying network perspectives in archaeology and history and considers the unique challenges presented by datasets in these disciplines, including the fragmentary and material nature of such data and the functioning and change of social processes over long timespans. An international and multidisciplinary range of scholars debate both the rationale and practicalities of applying network methodologies, addressing the merits and drawbacks of specific techniques of analysis for a range of datasets and research questions, and demonstrating their approaches with concrete case studies and detailed illustrations. As well as revealing the valuable contributions archaeologists and historians can make to network science, the volume represents a crucial step towards the development of best practice in the field, especially in exploring the interactions between social and material elements of networks, and long-term network evolution.

Abstract Over the past 15 years, waxing (hair removal) studios have emerged in central Berlin and grown rapidly in number. Specializing in the “Brazilian method,” this beauty salon sector has increasingly been occupied by Brazilian migrants. In addition to being a simple hair removal service, I argue that the intimate work carried out in these salons encompasses an educational and even civilizing effort from the point of view of Brazilian depiladoras: The intimacy of their work allows for affective encounters in which Brazilian women are not seen merely as service providers. They embody the specialist in a form of beauty and femininity that is desired by German clients. Appropriating these rare moments of intimacy, Brazilian depiladoras act as educators not only for a more hygienic and more feminine corporeality but also for a more humanized sociality with the “other.” Based on long-term ethnographic research in Berlin, I discuss both the agency of beauty work and its limits within the coloniality of feminized and ethnicized labor.

Btk Inhibitors

Bruton’s tyrosine kinase (BTK) represented, in the past ten years, an important target for the development of new therapeutic agents that could be useful for cancer and autoimmune disorders. To date, five compounds, able to block BTK in an irreversible manner, have been launched in the market, whereas many reversible BTK inhibitors (BTKIs), with reduced side effects that are more useful for long-term administration in autoimmune disorders, are under clinical investigation. Despite the presence in the literature of many articles and reviews, studies on BTK function and BTKIs are of great interest for pharmaceutical companies as well as academia. This review is focused on compounds that have appeared in the literature from 2017 that are able to block BTK in an irreversible or reversible manner; also, new promising tunable irreversible inhibitors, as well as PROTAC molecules, have been reported. This summary could improve the knowledge of the chemical diversity of BTKIs and provide information for future studies, particularly from the medicinal chemistry point of view. Data reported here are collected from different databases (Scifinder, Web of Science, Scopus, Google Scholar, and Pubmed) using “BTK” and “BTK inhibitors” as keywords.

The Moment

Abstract. The article analyzes the autobiography of the famous Russian philosopher, theologian and scientist Pavel Florensky, as well as those of his texts that retain traces of memories. According to Florensky, the personal biography is based on family history and continues in children. He addresses his own biography to his children. Memories based on diary entries are designed as a memory diary, that is, as material for future memories. The past becomes actual in autobiography, turns into a kind of present. The past, from the point of view of its realization in the present, gains meaning and significance. The au-thor is active in relation to his own past, transforming it from a collection of disparate facts into a se-quence of events. A person can only see the true meaning of such events from a great distance. Therefore, the philosopher remembers not so much the circumstances of his life as the inner impressions of the en-counter with reality. The most powerful personality-forming experiences are associated with childhood. Even the moment of birth can decisively affect the character of a person and the range of his interests. The foundations of a person's worldview are laid precisely in childhood. Florensky not only writes mem-oirs about himself, but also tries to analyze the problems of time and memory. A person is immersed in time, but he is able to move into the past through memory and into the future through faith. An autobi-ography can never be written to the end because its author lives on. However, reaching the depths of life, he is able to build his path in such a way that at the end of this path he will unite with the fullness of time, with eternity.

Place branding is a network of associations in the consumer’s mind, based on the visual, verbal, and behavioral expression of a place. Food can be an important tool to summarize it as it is part of the culture of a city and its symbolic capital. Food is imaginary, a ritual and a social construction. This paper aims to explore a ritual that has turned into one of the brands of Lisbon in the past few years. The fresh sardines barbecued out of doors, during Saint Anthony’s festival, has become a symbol that can be found on t-shirts, magnets and all kinds of souvenirs. Over the year, tourists can buy sardine shaped objects in very cheap stores to luxurious shops. There is even a whole boutique dedicated to the fish: “The Fantastic World of Portuguese Sardines” and an annual competition promoted by the city council to choose the five most emblematic designs of sardines. In order to analyze the Sardine phenomenon from a city branding point of view, the objective of this paper is to comprehend what associations are made by foreigners when they are outside of Lisbon. As a methodological procedure five design sardines, were used of last year to questioning to which city they relate them in interviews carried in Madrid, Lyon, Rome and London. Upon completion of the analysis, the results of the city branding strategy adopted by the city council to promote the sardines as the official symbol of Lisbon is seen as a Folkmarketing action. The effects are positive, but still quite local. On the other hand, significant participation of the Lisbon´s dwellers in the Sardine Contest was observed, which seems to be a good way to promote the city identity and pride in their best ambassador: the citizens.
