Until now, the properties of honey have been defined based exclusively on the content of plant components in the nectar of given plant. We showed that apalbumin1, the major royal jelly (RJ) protein, is an authentic and regular component of honey. Apalbumin1 and other RJ proteins and peptides are responsible for the immunostimulatory properties and antibiotic activity of honey. For the quantification of apalbumin1, an enzyme-linked immunosorbent assay (ELISA) was developed using polyclonal anti-apalbumin1 antibody. The method is suitable for honey authenticity determination; moreover it is useful for detection of the honey, honeybee pollen and RJ in products of medicine, pharmacy, cosmetics, and food industry, where presences of these honeybee products are declared. Results from the analysis for presence and amount of apalbumin1 in honeys will be used for high-throughput screening of honey samples over the world. On the basis of our experiments which show that royal jelly proteins are regular and physiologically active components of honey we propose to change the definition of honey (according to the EU Honey Directive 2001/110/EC) as follows: Honey is a natural sweet substance produced by honey bees from nectar of plants or from secretions of plants, or excretions of plant sucking insects, which honey bees collect, transform by combining with major royal jelly proteins and other specific substances of their own, deposit, dehydrate, store and leave in the honey comb to ripen and mature.

This study aims to: 1). Knowing the development of Apis Cerana Honey BeesF.with extractor engine innovation 2). Control of pests that attack honey bees 3). Obtain products from honeybeesApis Cerana F.produced 4). Predict to what extent the quantity and quality of royal jelly products Apis cerana F.produced in the development of beekeeping in North Sulawesi, especially Kumelembuai Village, South Minahasa Regency. This research is expected to develop beekeeping in North Sulawesi, specifically the local bee Apis cerana in Kumelembuai Village. The benefits obtained from beekeeping development activities include increasing the income and nutritional quality of the community from beekeeping products such as honey, pollen, royal jelly, beeswax, propolis, bee venom. Conservation of natural resources, honey bees play an important role in helping the process of pollinating plants, in addition to beekeeping activities can also increase public awareness to participate in conservation efforts. North Sulawesi, especially in the village of Kumelembuai, can be developed using the methodqueen rearing best because it has bright prospects for cultivation in North Sulawesi. Honey bee cultivation is very profitable, in addition to increasing agricultural production (crop yields) and producing products from beesApis cerana namely honey, royal jelly, tepung sari, propolis, wax, bee venom which can all be utilized for human welfare. A number of studies have been carried out by various parties who feel an interest in the development of beekeeping, but the research conducted is still partial and limited to one or two environmental components, not integrated yet. It is hoped that this research can produce the best methods for developing beekeeping in the North Sulawesi kumelembu village. The research location will be conducted in the village of Kumelembuai, South Minahasa regency, North Sulawesi.

Abstract The aim of this paper is to assess if and how a concept of accounting quality differs from perspectives of various types of organisations affected by the accounting harmonisation process. Accounting harmonisation is commonly associated with worldwide adoption of IFRS by public interest companies. However, in the EU this process is much broader and also involves efforts to harmonise accounting standards for non-listed companies and public sector organisations. Analysis of the previous scientific research revealed that accounting quality was commonly assessed from IFRS users’ perspective and approximated with the quality of financial statements. However, based on the interviews with experts of Lithuanian accounting market, the concept of accounting quality for small and medium companies and public sector institutions is ambiguous and still needs to be clarified. Definition of accounting quality only as the quality financial statements is too narrow as financial disclosure is not that important for such companies. For non-listed companies and public sector organisations, other aspects and factors, such as qualification of accountants, supervision of accounting and reporting, overall and managers’ perspective on importance of accounting, have more importance while defining accounting quality.

Smart Villages is an approach to rural development which has been under discussion in the EU as one of the subthemes that the ENRD is working on. For this reason, the Thematic Group (TG) on Smart Villages was launched in 2017. Since then it has been contributing to the definition of smart villages, discussing the changes in rural development policy and opportunities for providing support for smart villages, exchanging experience and best practices in smart rural development, and serving as a forum for dialogue between various rural stakeholders. This paper outlines the discussion held during the selected meetings of the TG and briefly indicates the academic background of the approach discussed. Its aim was to present Smart Villages in terms of EU policy. Hence, the paper presents the genesis of the EU debate, highlights some of the dilemmas of the definition of smart villages, indicates the role of the territorial governments and the EU in creating the conditions for implementing the approach, and shows the selected examples of smart rural development. Smart Villages is an alternative way of thinking about the quality of rural life, and it seems to respond to the way the EU policy is evolving. However, it calls for better tailored tools and instruments, which applies both to EU policies and national/regional sources. It also calls for regional and local governments to play their role in the process.

Through group thinking and thorough research, this article critically examines the democratic quality of the June 2016 UK referendum on EU membership. The Brexit ‘mandate’ is based on 52% of the voters but just 26% of the UK population. On a rigorous scrutiny, the referendum failed key tests on democratic legitimacy, such as human rights and the definition of the franchise. The UK Referendum Act 2015 excluded 3.3 million settled EU citizens from the franchise, which cast serious doubts: the political and legal status of common EU citizenship conferred by EU Treaties (based on equality and non-discrimination on grounds of nationality) was disregarded by the UK and by the EU. The article concludes that a democracy which intentionally excludes and marginalizes a whole group within its own political community is not legitimate enough.

AbstractAlthough EU member states have committed themselves to upholding the fundamental democratic values enshrined in Article 2 Treaty on European Union, violations of these values could be observed in some member states—first and foremost in Hungary and Poland. This article studies whether these negative developments, which are often summarized under the terms backsliding or erosion of democracy, should be classified as a loss in the quality of democracy or even as a decline of democracy. By drawing on Gero Erdmann’s (2011) theoretical definition of decline of democracy and using Democracy Barometer data for the period between 2004 and 2016, this form of loss of the quality of democracy is analysed for the 28 EU member states. In addition, the EU’s role in safeguarding democracy in its member states is discussed. The article shows that it is not only the new EU members that show a decline of democracy more frequently, but the old EU members. The EU as guardian of the democratic fundamental values is failing to live up to its role despite the numerous instruments it has at its disposal.

During the past investigations of immunoferritin localization of intracellular antigens in ultrathin frozen sections, we found that the degree of negative staining required to delineate u1trastructural details was often too dense for the recognition of ferritin particles. The quality of positive staining of ultrathin frozen sections, on the other hand, has generally been far inferior to that attainable in conventional plastic embedded sections, particularly in the definition of membranes. As we discussed before, a main cause of this difficulty seemed to be the vulnerability of frozen sections to the damaging effects of air-water surface tension at the time of drying of the sections.Indeed, we found that the quality of positive staining is greatly improved when positively stained frozen sections are protected against the effects of surface tension by embedding them in thin layers of mechanically stable materials at the time of drying (unpublished).

The article describes the results of comprehensive study aiming at increase of quality of LED luminaires and definition of the nature of changes in their correlated colour temperature (CCT) in the course of operation. Dependences of CCT of LED luminaires with remote and close location of phosphor for 10 thousand hours of operation in different electric modes were obtained; the results of comparison between the initial and final radiation spectra of the luminaires are presented; using mathematical statistics methods, variation of luminaire CCT over the service period claimed by the manufacturer is forecast; the least favourable electric operation modes with the highest CCT variation observed are defined. The obtained results have confirmed availability of the problem of variation of CCT of LED luminaires during their operation. Possible way of its resolution is application of more qualitative and therefore expensive LEDs with close proximity of phosphor or LEDs with remote phosphor. The article may be interesting both for manufacturers and consumers of LED light sources and lighting devices using them.

In the discussion on the future of the EU, the topic of differentiated integration has become a strategic issue, with different variants beginning to appear as modus operandi of the European Union, which has become a subject of controversy among Member States. Significantly, the debate on differentiated integration began to be accompanied by reflections on disintegration. This article attempts to define disintegration on the assumption that it should be defined through the prism of integration, and that such a defining process can not be limited to concluding a one-way contrast between disintegration versus integration and vice versa. This is due to the assumption that the European Union is a dichotomous construct in which integration and disintegration mutually exclude and complement each other. This dichotomy is most evident in the definition of integration and disintegration through the prism of Europeanisation top-down and bottom-up processes that generate, reveal, visualize, stimulate integration mechanisms what allows to diagnose their determinants.
