Wykonano badania składu frakcyjnego pyłów emitowanych z procesu spalania węgla kamiennego w paleniskach domowych oraz badania uwalniania się rtęci, cynku, ołowiu i miedzi z węgla spalanego w tych źródłach. Emisje metali charakteryzowano przez wyznaczanie współczynników podziału K, który wyraża stosunek mas metalu emitowanego do powietrza do masy tego metalu zawartej w jednostkowej ilości węgla przed spaleniem. Wyznaczone wartości K cynku, ołowiu i miedzi wynosiły odpowiednio 0,59, 0,33 i 0,34 ze współczynnikami zmienności tego parametru wynoszącymi odpowiednio 37, 46 i 44%. Dużo lepszą powtarzalność wartości K, wynoszącą 17%, uzyskano w przypadku Hg. Stwierdzono, że w procesie spalania węgla kamiennego w paleniskach domowych 52% rtęci zawartej w węglu emitowane jest do powietrza w postaci gazowej. Badania emisji pyłu z palenisk domowych wykazały, że w poszczególnych frakcjach pyłów emitowanych z 7 badanych źródeł spalania przeważały emisje frakcji drobnych. Średnio około 76% emitowanych pyłów mieściło się we frakcjach o wymiarach ziaren do 12 μm, czyli należących do frakcji pyłu zawieszonego. Udział frakcji ziaren w zakresie od 12 do 29 μm wynosił 9%. Dane te wskazują, że oddziaływanie emisji pyłów z tych źródeł nie ogranicza się do zasięgów lokalnych, lecz pyły te i zawarte w nich metale mogą być przenoszone w atmosferze na znaczne odległości.

The aim of this paper is twofold. Firstly, I present the scholarly book publications patterns of Polish scholars. Secondly, I show how scholarly book publications are assessed in various European research evaluation systems. Moreover, I argue that the diversity of evaluation models depends on the scientific policy aims in a given country. This presentation of European models allows me to discuss a new Polish science policy instrument, that is the list of publishers prepared for the upcoming evaluation exercise in 2021. In 2018, the Ministry of Science and Higher Education in Poland implemented a new model of scholarly book publication assessment based on the list of publishers. On the one hand, such a science policy instrument might be a way to appreciate the best quality scholarly books and give them more points than articles in the evaluation exercise. On the other hand, it is a so far unknown instrument which differentiates publications that have been treated the same up to date. Additionally, this paper aims to shed some light on how the new Polish model was prepared.

Ocean law has developed greatly in the recent years as an area within maritime law and environmental law. The increased attention has been received mainly due to the sea- level rise, ocean acidification and changing ocean currents caused by climate change. The negative impacts of climate change affect a wide spectrum of law and policy and have direct and indirect implications on various aspects such as: international security, food security, shipping, fisheries, marine and coastal governance etc. According to the IPCC 2018 Report, ocean ecosystems are already experiencing large-scale changes and critical thresholds are expected to be reached at higher levels of global warming. The main aim of this article is to present how the ocean law and climate law respond to the regulatory challenges caused by climate change.

Each year, mine and mill operations generate enormousamounts of two waste types – fine-grained tailings andcoarse-grained waste rocks. Fine-grained tailings are either discharged in slurry form to surface tailings dams ordelivered in cementitious form to underground mine stopes as backfilling, while coarse-grained rocks are typicallystored by depositing as a dry material in large dumps. The engineering design of surface tailings dams orunderground mine stopes is often controlled by the high compressibility and low shear strength characteristics offine-grained tailings. Cemented paste backfill CPB indicating saturated, fine-grained backfills can undergo majorconsolidation settlement during early curing stages. Thus, a better understanding of the rate and magnitude of bothdifferential and total settlement of CPB cured under stressis essential for a proper backfill geotechnical design. Theconsolidation parameters of CPB can be determined from an improved lab setup called CUAPS (curing underapplied pressure system). This setup is capable of simulating the CPB placement and curing conditions, andmeasuring the consolidation parameters of CPB cured under effective stresses ranging between 0.5 and 400 kPa.In this study, a series of one-dimensional consolidation tests were conducted on CPB samples allowing forexamination of the effects of binder type and rate as well as curing time on the compression properties (e.g.,coefficient of consolidationcv, compression indexCc, and recompression indexCr) and the final geotechnicalindex properties (e.g., void ratioef, water contentwf, and degree of saturationSf). Results showed that as the bindercontent increases, the initial resistance to consolidation increases. Thecvvalue decreases over the course of timedue to evolution of the CPB microstructure generated by the hydration process.

This article focuses on the emotionality of belonging among European Union (EU) citizens in the context of the United Kingdom’s (UK) 2016 referendum and its result in favour of the UK leaving the EU, commonly referred to as Brexit. Drawing from testimonies of EU27 citizens in the UK (mainly mid- to long-term residents) published in a book and on blog and Twitter accounts by the not-for-profit and non-political initiative, the ‘In Limbo Project’, it explores a range of emotions which characterise the affective impact of Brexit and how they underpin two key processes disrupting the sense of belonging of EU citizens: the acquisition of ‘migrantness’ and the non-recognition of the contributions and efforts made to belong. The resulting narratives are characterised by senses of ‘unbelonging’, where processes of social bonding and membership are disrupted and ‘undone’. These processes are characterised by a lack of intersubjective recognition in the private, legal and communal spheres, with ambivalent impacts on EU citizens’ longer-term plans to stay or to leave and wider implications for community relations in a post-Brexit society.

Reliable knowledge of thermo-physical properties of materials is essential for the interpretation of solidification behaviour, forming, heat treatment and joining of metallic systems. It is also a precondition for precise simulation calculations of technological processes. Numerical calculations usually require the knowledge of temperature dependencies of three basic thermo-physical properties: thermal conductivity, heat capacity and density. The objective of this work is to find a correlation that fits the thermal conductivity of selected steel grades as a function of temperature (within the range of 0–800°C) and carbon content (within the range of 0.1–0.6%). The starting point for the analysis are the experimental data on thermal conductivity taken from literature. Using the method of least squares it was possible to fit an equation which allows calculating the thermal conductivity of steel depending on the temperature and carbon content. Two kinds of equations have been analyzed: a linear one (a linear model) and a second degree polynomial (a non-linear model). The thermal conductivity obtained by linear and nonlinear models varies on average from the measured values by 3% and 2.6% respectively.
