This paper presents an analysis of natural mineral waters recognized by EU member states (on the basis of being announced in the Official Journal of the European Union) and originating in Polish territory. For each of these waters, calculations were made in relation to the Langelier saturation index, Ryznar stability index, and indices S1 (effect of chloride and sulfate ions on iron and steel), S2 (effect of nitrate ions on zinc), and S3 (effect of bicarbonate/sulfate ratio on copper). The impact of mineral waters on copper, hot-dip galvanized iron, stainless steel, acid-resistant steel, cast iron, low-alloy steel, and nonalloy steel was assessed on the basis of the indices calculated. The analysis allowed determination of the possibility of these measures being used in assessing the performance of mineral water installations.

If local authorities units carry out an economic activity, are considered to be taxable under Act No. 235/2004 Coll., On Value Added Tax as amended. Adjustment of VAT in all countries of the European Union is based on Council Directive 2006/112/EC of 28 November 2006 on the common system of value added tax as amended. The application of this directive is binding for all EU member states and national treatment of VAT may diverge from the Directive only in cases where the Directive permits. Decisions of the European Court of Justice are of considerable importance during the interpretation of the Czech VAT Act.For the municipalities and regions article defines the activities that are considered to be an economic activity and activities that are deemed to exercise of public administration and are not therefore subject to VAT. Further the paper defines the concept of turnover of local authorities. At paper there are evaluating the impact of the application of VAT on municipalities and regions in the provision of the individual fulfillment. Great attention must municipalities and region devote to the problem of correct application of claim to tax deduction if they carry out the exercise of public administration, taxable activities and fulfillments exempt from VAT.

Despite recent concerns about the increasing influence of outside investors on the European Union (EU) and Western Balkans, the developed European countries are still a dominant source of foreign direct investment (FDI) in the region, confirming the benefits of EU membership. At the same time, fast-growing connectivity and lower trade costs in accession and neighboring countries determine the FDI growth from China, particularly via the Belt and Road Initiative (BRI). By applying panel data over 2000-2019 for 34 countries, which form 89% of all European FDI, we first examine FDI patterns around Europe, compare the EU, NMS, and Western Balkans; verify the importance of EU membership for FDI, caused reducing trade costs and improving connectivity. Thus, the new EU member states (NMS) and Western Balkans appear both as a home country and as a pre- entry destination to the EU. Then, we calculate trade costs indices for each selected country and partners over time and find that Europe and China are closely interconnected through trade and FDI. It means that stronger ties with China can be realized for the sample countries at the cost of easing relations with the EU. Finally, incorporating trade costs indices into the FDI model; we evaluate the impact of connectivity on FDI and estimate how BRI affected FDI in Europe. Additionally, we validate that the old framework of horizontal and vertical FDI not representative well and even new complex vertical or export-oriented FDI strategies are shifting today.

This chapter discusses the impact of CJEU copyright case law on national copyright regimes, even beyond the wording of EU directives as transposed into national legal systems. To this end, it focuses on the UK and, following a discussion of what immediate changes the departure from the EU and the EEA (Brexit) would have (also with regard to issues of exhaustion), it explores to what extent case law of the Court of Justice of the European Union (CJEU) has changed UK copyright law. EU decisions have had an impact in areas such as: copyright subsistence, subject matter categorization, primary/accessory liability, standard of infringement, exceptions and limitations, and enforcement (with particular regard to website blocking jurisprudence). Overall, this chapter shows the legacy of CJEU case law, and how pervasive the impact of such case law is.

A high concentration of aggressive carbon dioxide disturbs many technological processes in water treatment. It also causes the development of corrosion in steel and concrete. De-acidification of groundwater by means of air bubbles alters pH and the concentration of aggressive carbon dioxide. This was investigated for the variables of air flow (Q = 20–50 L h−1) and height of water layer (H = 25–75 cm) as well as aeration time (t = 0–20 min). The obtained three-parameter models showed good correlation with the experimental results, except in a few cases where r2 was bigger than 0.9. Furthermore, they allow for prediction of an increase of pH and a decrease in concentration of aggressive carbon dioxide in aerated water. The effectiveness of de-acidification of groundwater was evaluated using indices of water stability (Langelier Saturation Index, Precipitation Index, Ryznar Stability Index, Aggressiveness Index and Index of Aggressiveness). Although as a result of aeration an increase of pH over 7 was observed, the non-corrosive values of the indices were not reached. This was due to a very low alkalinity of water, which was 0.7 meq L−1.

AbstractSince the 1970s, the Publications Office of the European Union, the official publisher of all the institutions and bodies of the EU, has had to adapt to a fast-changing situation as the number of EU Member States has grown and the number and nature of publications has evolved (including publishing public tenders of EU institutions and Member States in 1978 through a supplement to the Official Journal of the European Union and handling CELEX, an interinstitutional and multilingual automated documentation system for community law, in 1992). These changes occurred over several ages of computing. The computerisation of the Publications Office was primarily a response to the need for rationalisation and productivity, but the aim was also to gradually adapt to new types of document publication and consultation. These different stages of digitalisation required the constant transfer of information to a multitude of media. Supports, such as punched cards, optical discs and CD-ROMs, had varying life expectancies and are all evidence of attempts to digitise information before the Web.This evolution not only illustrates the need to constantly harmonise a large amount of information, it also highlights some continuities. It affects the management of information systems but also meets regularly updated standardisation, interoperability and sustainability needs within a complex ecosystem.

The article identifies the impact of agricultural policy on the development of state regulation of the economies of European Union member states (EU). The main reason for the implementation of the Common Agricultural Policy (CAP) for EU member states has been identified. Some key reforms have been analyzed implemented within the integration association. It was found that the reform of CAP is due to the need to address market price uncertainty, respond to expanding access to the EU market by free trade agreements, use digital technologies to improve the accuracy and efficiency of CAP tools, accelerate their practical application, increase attention to environmental issues, environment, and climate change. The article also presents the main economic and social goals of the CAP, which are included in the Treaty on the Functioning of the European Union. It is established that the institutional component of the CAP reform is reflected in the introduction of proposals into the legislative framework of the CAP for the period 2021-2027. The proposals of the European Commission were formulated in nine key objectives, which are considered in this article. Some tools, requirements for their use, and indicators for measuring progress towards the nine specific objectives of the CAP, which the European Commission has proposed to EU member states to achieve the defined goals are also analyzed. The CAP EU budget for 2014-2020 is considered and compared with the proposed budget for 2021-2027 (in constant 2018 prices).

Abstract In the present study coagulation process was used as pretreatment for the RO membrane with turbid raw water collected from Bisalpur Dam, Rajasthan, India. To optimize coagulation performance, three kinds of coagulants, namely, Alum (commercially available), synthesized inorganic polymeric coagulant-medium basicity (IPC-M), and inorganic polymeric coagulant-ultra high basicity (IPC-UH) were examined for turbidity removal with varying operating parameters. It was observed that in the optimum pH range of 6–7, the IPC-UH resulted as the best performing coagulant with 0.99 mg/L equivalent Al2O3 dose revealing 2 NTU residual turbidity and residual aluminium of 0.001 mg/L. Moreover, Langelier saturation index and Ryznar stability index values were evaluated at optimum conditions of all the three coagulants proclaiming negligible scaling potential. Furthermore, the coagulant-treated water (100 L) was fed to the RO membrane, and the performance was noted in terms of flux, pressure, and TDS. It was observed that IPC-UH has the lowest reduction in permeate flux of 0.78 L/min/m2 compared to commercially available coagulant alum (0.90 L/min/m2). Also, the increased feed pressure was observed for all the coagulants treated water with the lowest value of 2.3 kg/cm2 for IPC-UH, which was 2.5 kg/cm2 for Alum (commercially available coagulant). Henceforth, integration of coagulation before the RO system resulted in effective pretreatment of turbid water with very minute scaling.
