This paper offers an analysis of the ethical values that have accompanied human exploration of space so far, and emphasizes the need to infuse human space activity with new ethical values by means of new and well-constructed legislation. One of the values that we deem particularly important in the creation of a new approach towards space exploration is care for the natural environment, including the space environment.

AbstractIn the last decade, self-healing materials have become extremely appealing for the field of space applications, due to their technological evolution and the consequent possibility of designing space systems and structures able to repair autonomously after damage arising from impacts with micrometeoroids and orbital debris, from accidental contact with sharp objects, from structural fatigue or simply due to material aging. The integration of these novel materials in the design of spacecraft structures would result in increased reliability and safety leading to longer operational life and missions. Such concepts will bring a decisive boost enabling new mission scenario for the establishment of new orbital stations, settlement on the Moon and human exploration of Mars.The proposed review aims at presenting the newest and most promising self-healing materials and associated technologies for space application, along with the issues related to their current technological limitations in combination with the effect of the space environment. An introductory part about the outlooks and challenges of space exploration and the self-healing concept is followed by a brief description of the space environment and its possible effects on the performance of materials. Self-healing materials are then analysed in detail, moving from the general intrinsic and extrinsic categories down to the specific mechanisms.

Debris Impact

AbstractIn the last 40 years, the increased space activity created a new form of space environment of hypervelocity objects—space debris—that have no functional use. The space debris, together with naturally occurring ultrahigh velocity meteoroids, presents a significant hazard to spacecraft. Collision with space debris or meteoroids might result in disfunction of external units such as solar cells, affecting materials properties, contaminating optical devices, or destroying satellites. The collision normally results in the formation of additional debris, increasing the hazard for future missions. The hypervelocity debris effect is studied by retrieving materials from space or by using ground simulation facilities. Simulation facilities, which include the light gas gun and Laser Driven Flyer methods, are used for studying the materials degradation due to debris impact. The impact effect could be accelerated when occurring simultaneously with other space environment components, such as atomic oxygen, ultraviolet, or x-ray radiation. Understanding the degradation mechanism might help in developing materials that will withstand the increasing hazard from the space debris, allowing for longer space missions. The large increase in space debris population and the associated risk to space activity requires significant measures to mitigate this hazard. Most current efforts are being devoted to prevention of collisions by keeping track of the larger debris and avoiding formation of new debris.

History books are rife with examples of the role of nutrition in determining either the success or the failure of human exploration on Earth. With planetary exploration in our future, it is imperative that we understand the role of nutrition in optimizing health before humans can safely take the next giant leaps in space exploration.

As a result of environmental changes, assessment indexes for the agricultural landscape have been changing dramatically. Being at the interface of human activity and the natural environment, hunting is particularly sensitive to environmental changes, such as increasing deforestation or large-scale farming. The classical categorisation of hunting grounds takes into account the area, forest cover, number of forest complexes, fertility of forest habitats, lack of continuity of areas potentially favourable to wild animals. Landscape assessment methods used in architecture often better reflect the actual breeding and hunting value of a given area, especially in relation to fields and forests. The forest-field mosaic, large spatial fragmentation as well as interweaving of natural environment elements with buildings do not have to be the factors that limit the numbers of small game. Identification of the constituents of architectural-landscape interiors: content and significance assessment, determination of the functional role or assessment based on the general environmental values being represented take into account factors important for the existence of game, in particular small game.

Soft Belarusization: (Re)building of Identity or “Border Reinforcement”The paper focuses on shifts in official discourse in Belarus since 2014, after the Ukrainian events, that are labelled “soft Belarusization”. This new approach can be interpreted as an attempt to support nationally oriented identity practices and as an attempt to establish more visible political and cultural boundaries between Belarus and the “Russian world”. Firstly, this paper elaborates on the specifics of Belarusian identity and presents the historical and political background of the ongoing events. Secondly, several manifestations of soft Belarusization processes are analysed, such as changes in Belarusian authorities’ rhetoric, their changing attitude towards Belarusian and unofficial state symbols and previously officially disregarded historical events and personalities, steps towards the creation of new symbols, and new relationships between official and “alternative” discourses. Мягкая белорусизация: возрождение идентичности или «укрепление границ»?В статье рассматриваются сдвиги, происходящие в официальном дискурсе в Беларуси после украинских событий 2014 г., получившие условное название «мягкая белорусизация». Данный подход может рассматриваться как попытка поддержать национально- ориентированные идентичностные практики, а также как попытка провести более заметные политические и культурные границы между Беларусью и «Русским Миром». В первую очередь в статье говорится о некоторых спецификах белорусской идентичности и представляется исторический и политический фон происходящих событий. Затем анализируются некоторые проявления «мягкой белорусизации»: изменение риторики официальных представителей республики; изменения в их отношении к белорусскому языку и неофициальным государственным символам, а также к историческим личностям и событиям, которые в недалеком прошлом обходились стороной; шаги по созданию новых символов; новые отношения между официальным и «альтернативным» дискурсом. Miękka białorutenizacja: (od)budowa tożsamości czy „wzmacnianie granic”?Artykuł poświęcony jest zmianom w oficjalnym dyskursie publicznym na Białorusi, jakie obserwować można po 2014 roku, czyli po wydarzeniach na ukraińskim Majdanie, określanych mianem „miękkiej białorutenizacji”. To nowe zjawisko może być interpretowane jako próba wspierania narodowo zorientowanych praktyk tożsamościowych, a także jako próba ustalenia bardziej widocznych granic politycznych i kulturowych między Białorusią a „światem rosyjskim” (russkij mir). Przede wszystkim w artykule mowa jest o specyfice tożsamości białoruskiej oraz o tle historycznym i politycznym aktualnych wydarzeń. W następnej kolejności analizowane są niektóre przejawy „miękkiej białorutenizacji”: zmiany w retoryce władz białoruskich, ich zmieniający się stosunek do języka białoruskiego i nieoficjalnych symboli państwowych, a także wcześniej negowanych wydarzeń i postaci historycznych oraz kroki podejmowane w kierunku tworzenia nowych symboli, a także budowania relacji między dyskursem oficjalnym a „alternatywnym”.

Chapter 3 offer a new approach to the evidence that takes into account not just continuities with Persian practice, but also the Seleucid Empire’s breaks with Achaemenid traditions. I argue that the Seleucid Empire strategically introduced stark and deliberately instituted changes in the Iranian world’s topography of power, architecture and religious traditions to create a new vision of Iranian, though not necessarily Persian, kingship. The Seleucids’ new topography of power and visual and ritual expressions of Irano-Macedonian charismatic kingship subsumed and transcended the traditions of Persia and Babylon alike. Ultimately, they laid the groundwork for new Iranian kingship.

To increase the public’s awareness of and exposure to animals needing homes, PetRescue, Australia’s largest online directory of animals in need of adoption, lists all currently available animals from rescue and welfare shelters nationwide. The current study examined the photographs in the PetRescue online profiles of the three most common breeds within these data, namely, Staffordshire bull terriers (n = 3988), Labrador retrievers (n = 2246), and Jack Russell terriers (n = 2088), to identify the inferred preferences of potential adopters. By investigating the attributes of these photographs, we were able to identify visual risk factors associated with protracted lengths of stay (LOS). The longest stays were associated with dogs with erect ears and those photographed in a natural environment, i.e., 18.32 days and 19.57 days, respectively. Dogs photographed in a kennel and with mouths closed had the shortest LOS, i.e., 11.54 d and 14.44 d, respectively. Heightened awareness of the roles of photographic attributes in generating interest among potential adopters may increase the speed of adoption by guiding the creation of online profiles and selection of photos to optimise the promotion of dogs at risk of long stays.
