APPROVED ; The work which follows examines the process by which private actors in the digital market are redefining fundamental rights through their contractual terms and practical operation. The argument is allied to works which consider ?digital constitutionalism,? the idea that private actors in the digital market are increasingly displaying constitutional features through their contractual terms and documents. Unlike a majority of work in the area of digital constitutionalism the work does not argue that private actors setting rights based standards represents a positive development. Rather, the work argues that private actors, through their re-definition of public, normative standards are generating a body of rules and practices which have displaced democratically decided rights standards with negative consequences for individual autonomy and the Rule of Law. The work argues that this process has been enabled by three features of EU law and policy. The first is an approach of functional equivalence to laws governing the digital market. In accordance with this approach the digital market has been treated as equivalent to traditional markets and its participants are viewed as requiring no additional or supplementary protections or regulations. Of particular significance in functionally equivalent attitudes to the digital market is the Union?s deference to freedom of contract as part of an ordoliberal attitude to market regulation. While this attitude is now beginning to erode (to some extent) in the context of data protection it remains the dominant regulatory approach of the European Union in the digital market. The second feature, not unrelated to the first, is the Union?s preference for economic rather than socially orientated standards and protections in it policies as well as its secondary laws. As part of this preference, when fundamental rights cross the Rubicon from vertically enforced constitutional protections to horizontally enforceable legislative ones their content is transmuted in a manner which favours their economic over socially oriented aspects. The third feature, is what is referred to within the work as the Union?s brittle constitutionalism ? that is the Union?s hesitant and incomplete articulation of and commitment to rights enforcement. This feature is the result in part of the Union?s ambiguous and at times hostile attitude to the development of fundamental rights policy. The work examines the impact of these trends and the rise of private policy they have generated on the rights to privacy and property under the Charter of Fundamental Rights.

Dam Safety and dam incidents are treated here looked at from the "Human Factors" perspective. An attempt is made to explore these factors as an important drive in impairing dams' safety and increases their risks. Distinction is drawn between the "Normal Human Caused Incidents" and the "Extraordinary Human Caused Incidents" together with the description of their root origins and subsequent consequences. The first type includes unintentional mistakes, errors and flaws committed by the operators of dams inadvertently, in addition to negligence, lack of experience or overconfidence. Such failings can happen in manual operation of dams, or through the use of their Supervision, Control and Data Acquisition (SCADA) systems as in industrial control system (ICS). They can occur also due to flaws in software or even in the application of information and communication technology (ICT) in remote control operations. As for the second group; the extraordinary human factors, they are defined here as those committed by man with the full understanding of their possible damage. They are done purposely for destabilizing dams after thoughtful and carefully meditated decision making process and they are manifested in acts of war, sabotage and terrorists actions. In this modern age, these acts are characteristics of hackers' attacks on dam(s) operating systems. This is done through the use of cyberspace by the widespread interconnected digital technology with the accompanying advances in the communication technologies. As such, these technologies have made remote control of such systems possible. Not limited to this, dams remain now, as they were always in the past, the obvious targets in wars and conflicts to inflict losses on the enemy and to use them as weapons, and for terrorism actions for challenging governments. Examples of the aforementioned threats are described with examples given from real cases to elucidate the dangers involved. Lessons to be learned from these incidents are derived and recommendations are presented to be followed to avoid risky situations. ; Validerad;2020;Nivå 1;2020-09-29 (johcin)

When a dam is built, its safety becomes a constant concern for the owner, the public and for governments. Therefore, continuous observation through routine inspections and safety reviews become necessary. Acting as protectors of public safety, governments and professional organizations save no effort in the promulgation of legislations and laying out guidelines for such inspections and reviews. These issues are discussed here starting with the basic first step of visual inspections by the operators and the follow up of detailed safety reviews by specialists. Careful visual inspections assisted by instrumentation measurements may reveal an early negative issue such as, but not limited to, increased seepage, increased uplift pressure, signs of weakness like cracking in the body of the dam, or dams' slope sloughing, and even damaged hydraulic control equipment. Documenting and reporting these observation helps in taking remedial measures in good time and may lead to more intensive safety reviews. Suggested check lists for the inspection engineers are given here, but these may be tailored for each dam according to its needs. These lists cover issues common to both embankment and concrete dams, and include other specific issues related to each type of them. Metal equipment take their share by listing such areas as corrosion, fatigue and cracking, tear, and wear and so on. Instrumentation measurements are also given their due consideration by giving brief mention of types of measurements needed and points to be observed in instrumentation control work. Finally, guidelines, rules, and legislations for Dam Safety Reviews are generally discussed giving examples from four countries in the world. ; Validerad;2020;Nivå 1;2020-09-29 (johcin)

The PhD thesis was embedded in the Energy for Smart Objects (EnSO) project, which is part of the Electronic Components and Systems for European Leadership (ECSEL) Joint Undertaking in collaboration with the European Union's H2020 Framework Program (H2020/2014-2020) and National Authorities, with the aim to develop Autonomous Micro Energy Sources (AMES) for smart objects. In the framework of the EnSO project, the goal of the thesis was to develop a solid electrolyte for all-solid Li-metal microbatteries as energy storage device in AMES. Lithium metal is the anode material of choice because of its very high theoretical specific capacity of 3861 mAh/g, which is one of the important requirements for miniaturized batteries. However, inhomogeneous lithium depositions known as dendrites, which reduce the life time and can connect both electrodes and create a short circuit, are often observed when using Li-metal as anode. The aim is therefore to develop a solid electrolyte, which presents a high ionic conductivity for the Li ion transport and a high mechanical stability to hinder dendritic growth. Electrolyte solutions based on ionic liquids (ILs) with dissolved lithium salt can be confined into inorganic porous networks forming so called ionogels (IGs), which are investigated as quasi-solid electrolyte materials. In a first step, the synthesis in a one-pot sol-gel process for silica-based ionogels is developed and in a second step tested as quasi-solid electrolyte in Li/LiCoO2 systems. IGs were obtained by a sol-gel reaction between TMOS as silica precursor and TFA as catalyst in PYR13-FSI (IL) and LiTFSI (Li+ source). It was possible to synthesize transparent IG monoliths with gelation times of 2-3 h, which is a suitable time for the IG film preparation on the LCO cathodes. Four IGs with different compositions were prepared and characterized. Two types of silica matrices built of mostly threefold-condensed Si centers could be distinguished: a densely packed structure and an open-porous structure, the latter one corresponding to IG B with the molar ratios IL/TMOS=3, TFA/TMOS=0.3, H2O/TMOS=2.3. The ionic conductivity of the IGs could be linked to the silica matrix structure. Only the IG with the open-pore structure (IG B) has a good ionic conductivity (10−4 S/cm). Equally, the examination of the four IGs as thin film electrolytes in LCO/Li batteries show promising results for batteries containing IG B. However, the capacity lies under the theoretical value (89 mAh/g instead of 136 mAh/g) due to high cell resistance. Therefore, the ionic conductivity of IG B was improved by changing the synthesis process while keeping the composition unaltered. The new IG B∗ has a very good ionic conductivity (10−3 S/cm) but a poor mechanical stability due to a matrix structure of loosely connected silica particles. IG B∗ was not able to hinder dendritic growth. Thus, the PVDF-HFP polymer (20 wt.%) was added to B∗ (B∗-p), which enhanced the mechanical stability and the cyclability of the Li-ion batteries with B∗-p as electrolyte layer. No indication of dendrites was visible in the charge/discharge curve for minimum 30 cycles at C/5. The capacities are low (≤ 80 mAh/g) due to the decreased liquid (IL) to solid (SiO2 + PVDF-HFP) ratio, which results in a lower lithium ion mobility. In order to increase the battery capacity, the silica amount in the IG formulation was reduced, the LiTFSI lithium salt concentration was increased, and the Li+ source was modified by taking IL-based electrolyte solution with different concentrations of LiFSI. Indeed, the capacity increases with decreasing silica amount due to improved ion mobility. The change of the lithium concentration from 1M to 3M and 5M enhanced the capacity. A battery with the combination of the reduced silica amount (0.5 TMOS) and 5M electrolyte solution has a good capacity (> 100 mAh/g) for at least 10 cycles at C/5. The lithium salt LiFSI has a smaller anion than LiTFSI and thus, it can further improve the ion mobility in the IG electrolyte film. All IGs containing LiFSI have a higher ionic conductivity than the corresponding gels with LiTFSI. Overall the battery performance and reproducibility could be greatly improved. Batteries containing a solid electrolyte with 20 wt.% PVDF-HFP and the reduced TMOS amount with a 3M LiFSI solution are able to cycle without the appearance of dendrites for 13 cycles at C/5 followed by 12 cycles at C/2 with a rather good coulombic efficiency around 95%. However, the capacity remains under the theoretical maximum.

Transitioning into a sustainable energy system is becoming ever more pressing as the reality of an anthropogenic ecological crisis becomes difficult to ignore. Due to the complexity of the matter, proposed solutions often address the symptoms of the current socioeconomic configuration rather than its core. To conceptualise possible future energy systems, this Perspective focuses on the disconnect between science and technology and engineering studies. On the one hand, this disconnect leads to social science research that passively critiques rather than contributes to tackling societal issues in practice. On the other, it produces technical work limited by the incumbent conceptualisations of economic activity and organisational configurations around production without capturing the broader social and political dynamics. We thus propose a schema for bridging this divide that uses the "commons" as an umbrella concept. We apply this framework on the hardware aspect of a conceptual energy system, which builds on networked microgrids powered by open-source, lower cost, adaptable, socially responsible and sustainable technology. This Perspective is a call to engineers and social scientists alike to form genuine transdisciplinary collaborations for developing radical alternatives to the energy conundrum.

The Polish energy market heavily relies on coal. Pressured by the European Union, the Polish government has recently decided to accelerate coal phase-out and to gradually shut down all coal mines by 2049. In that context, it is necessary to assess the Polish energy market's state regarding energy efficiency, especially in the building stock. This paper aims to provide an overview of the current state of energy efficiency of residential buildings in Poland and insights into its future trends. A literature review was conducted, accompanied by focus group discussions with Polish building energy efficiency experts. The Polish energy sector is under a remarkable transformation that may be going too fast. A large gap between expectations, practices, and requirements can be observed. Raising awareness and capacity building in the energy efficiency sector, and a set of accessible guidelines should be developed so that the transformation is implemented correctly. A SWOT analysis results define the key opportunities and threats that are critical to meet net-zero emissions goals. The paper provides findings and insights on the 2020 targets status quo and raises awareness among stakeholders and fills a knowledge gap regarding energy efficiency in the Polish residential building stock. ; Peer reviewed

Unlike almost most other studies of neoliberal universities and academic capitalism this book ethnographically explores and interprets those transformations and their contradictions empirically in the everyday practices of students, faculty members, and administrators at two public universities: NTNU in Norway and UCLA in California.Differently situated in global political economies, both are ambitious, prosperous campuses. The book refl exively examines their disturbing disputes about quality, competition, and innovation. It argues that some academic, bureaucratic, and corporate university governance practices are both unsustainable and undermining what some university students and faculty already do well: circulate interdisciplinary knowledge and its making globally across the diasporic domains of academia, society, industry, and government while addressing the world's immediate challenges: power, inequities, and sustainability.It shows the important, strategic work of domesticating, co- morphing, and meshworking at the faultlines of emerging knowledge. This book is for students, faculty, society members, and policy makers who want to engage more effectively with contemporary universities that increasingly serve as busy crossroads for sharing ideas and how to make them. It will be of interest to workers and scholars in the interdisciplinary fi elds of higher education studies, critical university studies, and critical public infrastructure studies, plus science, technology, and society studies.

A study of the electronic conduction mechanisms and electrically active defects in polycrystalline Sb2Se3 is presented. It is shown that for temperatures above 200 K, the electrical transport is dominated by thermal emission of free holes, ionized from shallow acceptors, over the intergrain potential barriers. In this temperature range, the temperature dependence of the mobility of holes, limited by the intergrain potential barriers, is the main contributor to the observed thermal activation energy of the conductivity of 485 meV. However, at lower temperatures, nearest-neighbor and Mott variable range hopping transport in the bulk of the grains turn into the dominant conduction mechanisms. Important parameters of the electronic structure of the Sb2Se3 thin film such as the average intergrain potential barrier height ϕ = 391 meV, the intergrain trap density Nt = 3.4 × 1011 cm−2, the shallow acceptor ionization energy EA0 = 124 meV, the acceptor density NA = 1 × 1017 cm−3, the net donor density ND = 8.3 × 1016 cm−3, and the compensation ratio k = 0, 79 were determined from the analysis of these measurements. ; P.

As a direct bandgap semiconductor in both bulk and monolayer forms, ReS2 stands out for its unique distorted octahedral structure that results in distinctive anisotropic physical properties; however, only a few scalable synthesis methods for few-layer ReS2 have been proposed thus far. Here, the growth of high-quality few-layer ReS2 is demonstrated via sulfurization of a pre-deposited rhenium oxide coating on different semiconductor material nanowires (GaN, ZnS, ZnO). As-produced core-shell heterostructures were characterized by X-ray diffraction, scanning and transmission electron microscopy, micro-Raman spectroscopy and X-ray absorption spectroscopy. Experimental characterizations were supported by total energy calculations of the electronic structure of ReS2 nanosheets and GaN, ZnS, and ZnO substrates. Our results demonstrate the potential of using nanowires as a template for the growth of layered vdW materials to create novel core-shell heterostructures for energy applications involving photocatalytic and electrocatalytic hydrogen evolution. ; ERDF project number: 1.1.1.1/18/A/073.

Previous studies have shown that the use of zinc (Zn) chelate fertilizers combined with a nitrogen (N) fertilizer (urea) can lead to both agronomic (i.e., yields and Zn and N biofortification due to the synergies between both nutrients) and environmental (i.e., by reducing the emissions of nitrous oxide, NO, derived from N fertilization) benefits under rainfed semi-arid conditions. However, little is known about the effect of Zn-N co-fertilization on greenhouse gas (GHG) emissions or soil microbial processes involved in NO fluxes under non-flooded irrigated conditions (during the dry season). Under these conditions, water-filled pore space continuously fluctuates following a periodic pattern and soil temperatures are in the optimum range for soil microorganisms. In this context, a field experiment was conducted using a maize (Zea mays L.) crop treated with two N levels (no N application and 120 kg N ha as urea), and three Zn sources (no Zn application, Zn sulphate, and Zn applied with a mixture of chelating compounds, DTPA-HEDTA-EDTA). Nitrous oxide, methane (CH) and carbon dioxide (CO) fluxes were measured using opaque chambers, as well as the total abundances of soil bacteria, archaea and nitrifier and denitrifier communities. Zn-N co-fertilization increased cumulative NO emissions from 0.36 kg N-NO ha (for urea combined with Zn chelates) to 0.76 kg N-NO ha (for urea combined with Zn sulphate), with respect to urea without Zn application. The NO emission factors were lower (0.34%–0.72%) than the IPCC default value of 1%. Total abundances of the nosZ denitrification gene, which is involved in the reduction in NO to dinitrogen (N), were reduced by 75% on average in the plots that received Zn fertilizers. This reduction may explain the higher NO emissions in these treatments. In contrast with the case with non-irrigated crops, Zn-N co-fertilization cannot be recommended as a strategy to mitigate NO emissions in irrigated maize under semi-arid conditions, despite of the enhancement of Zn availability in soil. ; Financial support was provided by an ERDF-cofinanced grant AGL2015-64582-C3-3-R (MINECO-FEDER) from the Ministerio de Economía y Competitividad (Spanish Government).
