Abstract In recent years, the botanical and geographical origin of food has become an important topic in the context of food quality and safety, as well as consumer protection, in accordance with international standards. Finding chemical markers, especially phytochemicals, characteristic for some kind of food is the subject of interest of a significant number of researchers in the world. This paper is focused on the use of polyphenols as potential markers for the determination of botanical origin of honey. It includes a review of the polyphenols present in various honey samples and the methods for their separation and identification. Special emphasis in this paper is placed on the identification of honey polyphenols using advanced LC-MS techniques in order to find specific markers of botanical origin of honey. In this regard, this study gives an overview of the literature that describes the use of LC-MS techniques for the isolation and determination of honey polyphenols. This review focuses on the research performed in the past two decades.

“I think there’s a big strong belief in [...] the community … and maybe it’s in the world at large that somehow the doctors are more concerned about harvesting the organs than what’s best for the patient.”1 In the past 45 years, organ and tissue recovery and transplantation have moved from the occasional and experimental to a standard of care for end-stage organ failure; receiving an organ transplant is for many the only opportunity for increased quantity and/or quality of life. The increasing prevalence of diseases such as viral hepatitis, diabetes, and hypertension has significantly increased the incidence of end-organ failure. Additionally, surgical advances have permitted less stringent qualification criteria, so that people of advanced age or patients who may be in a physiologically fragile state are now eligible to be organ recipients. These changes have created a significant demand for organs.

Museums are a constantly developing segment of cultural tourism. Poland is in line with current trends in museums, expanding its offer and adapting it to the requirements of the world of contemporary image culture and multisensory experiences, which is increasingly dominated by technology. The authors of the paper undertook to recognise the specificity of military museums, by conducting a survey of approximately a third of all such institutions in Poland. Due to the subject-matter of their exhibitions, military museums create a broad field of research both in terms of aesthetics and museum practice, as well as the issues of shaping and maintaining collective memory and the identity of the nation. They form a special mirror in which the country’s ideas and aspirations are reflected more often than any real characteristics. In reference to contemporary trends in museums, the article aims to place Polish military museums between locality and universality, education and entertainment, stability and dynamism, knowledge and experience. The results obtained allowed the authors to distinguish three groups of military museums in Poland, as well as indicate conditions conducive to the further development of such attractions in the country.

The subject of this research is the works of the prominent national composer Alfred Schnittke. The analysis of musical compositions demonstrated that one of the dominant technique of their thematic development consists in the intonation and genre montage, and dramaturgy is structured as a peculiar intertwinement of imagery-thematic lines, each of which is formed as an assemblage of themes referred to the same genre. The main principle for this research served the principle of historicism as one of the fundamental within national musicology, which views an artistic phenomenon in unity of transformation of traditions and modern trends. The scientific novelty consists in determination of the leading principle of musical compositions of A. Schnittke – the principle of “generalization through the genre”, presented as an intonation and genre montage. In conclusions formulated in the article, the author summarizes and systematizes the results of study: combining different genres in a single sound space, the composer interprets them as so-called intonation-semantic signs formed in the process of prolonged historical-cultural development, generating valid content, and at the same time, in its intertwinement, creating an individual artistic view of the world.

The object of this article is professional activity of the British war correspondent Archibald Forbes during the Franco-Prussian War of 1870-1871. The subject is the perception and reflection of military realities (1870-1871) by the novice journalist. The goal consists in determination of the mechanisms of perception of participants and realities of the Franco-Prussian confrontation of 1870-1871 by the British correspondent A. Forbes. Intellectual history and imagological approach comprise the methodological framework of this research. Based on the analysis of documentary evidence left by A. Forbes, which describes the events of 1870-1871, the author was able to trace the evolution of Forbes’ perception of the Franco-Prussian campaign of 1870-1871. The conclusion is made on gradual changes in Forbe’s perception and reflection of war realities. The initial admiration was replaced by the professional subject-object description. However, his stance on parties to the conflict remained unchanged. The author assumes that A. Forbes had particular personal attitudes, but his perception of the war of 1870-1871 has evolved. The acquired results may be valuable in studying journalistic practice, as well as mutual perception of European ethnoses. The scientific novelty lies in a comprehensive approach towards the phenomenon at hand: the author examines not only the mechanisms of perception as such, but also their transformation influenced by various factors. This research made a transition from the widespread study of biographies and activity of correspondents of the XIX century to an extensive culturological and intellectual approach in consideration of professional practice of journalists of the past.

Despite modern writers noticing the importance of Premodern historiographical phenomena for a deeper comprehension of both Theory of History and History of Historiography, the Irish contribution to the subject is often left aside. Topics such as the Seanchas Tradition and Medieval Irish Classicism are not well integrated into such historiographical narrative. The Seanchaidh, the Irish Artifex of the Past, for example, is broadly mentioned as not a historian, but a chronicler, antiquary, genealogist, hagiographer or pedigree systematizer. This article addresses these issues and, more specifically, we focus on two Irish narratives produced in 7th century by Muirchú and Tírechán. Since they belong to the world of orality and bilingual literacy of Early Christian Ireland, perhaps their works could be understood as bounded by the Seanchas Tradition and Medieval Irish Classicism, hence, both could be considered as great examples of the producers of History and Historiography at the time.

In the past twenty years, there have been exciting new developments in the field of anthropology. This second edition of Barnard's classic textbook on the history and theory of anthropology has been revised and expanded to include up-to-date coverage on all the most important topics in the field. Its coverage ranges from traditional topics like the beginnings of the subject, evolutionism, functionalism, structuralism, and Marxism, to ideas about globalization, post-colonialism, and notions of 'race' and of being 'indigenous'. There are several new chapters, along with an extensive glossary, index, dates of birth and death, and award-winning diagrams. Although anthropology is often dominated by trends in Europe and North America, this edition makes plain the contributions of trendsetters in the rest of the world too. With its comprehensive yet clear coverage of concepts, this is essential reading for a new generation of anthropology students.

The new Corona-virus and the contagious disease which it causes, the so called COVID 19, put forward the serious challenges for many countries all over the world and for Georgia among them. Almost the whole world is facing very serious obstacles on the international and national levels. Too many problems emerged in the world countries. To resist against the new disease has become the main priority for each country. The global processes caused by the pandemics have influenced the audit service as well. The uncertainty and unpredictability caused the new risks of deficiencies and activated already existed ones in the new environment. The situation became more complicated due to the fact that it can happen that the auditors do not consider the mentioned risks in the process of planning for audits or the risks may be considered mistakenly. The firms and other economical institutions in which the audit is carried out are obliged to adopt the new rules and changing environments in which their businesses function; they should change the rules of fulfilling the operation, preparing the financial accounts, the processes of their representing the information processes, safety of information shown in the financial accounts, the rules of their preparing; they also evaluate the possibilities of keeping on their activities in the nearest future. The qualified performing of the audit implies the basical elemenst which helps to create such environment where the possibility of the high level audit will be at the maximum. Implementing the quality control implies that such system will include two stages; each of them is directed towards providing the audit processes according the international standards There are several types of the quality improvement system. In all of them the main variable value represents the amount of costs for the proper system. All countries choose the system which provides benefits taking the costs into consideration. There are four main stages in the process of implementation the system which will ensure the high quality audit. Here are four main stages shown in the process of implementation:  The first stage: to carry out diagnostic observation;  The second stage: stating the view;  The third sage: working out the system;  The fourth stage: implementation of the system. The firms and other economical institutions where the audit is carried out are obliged to be reliable with their activities in the changing situation in which their businesses function. The subjects change the rules of carrying out the usual operations, change the open information given in the financial accounts, and estimate the possibilities of maintaining the existing possibilities for the nearest future. It is important to revise some standards out of Audit International Standards and to make them fit for revealing and assessing the risks of essential mistakes and discrepencies. The controlled variation of the standard regulates such issues as the newly corrected risks caused by influences of COVID-19 pandemic on the planned approaches to the audit and also, evaluation of the risks already defined and making changes in them taking into consideration the influence of the errors in the risk evaluations and influence made upon the planned evaluations and audits the changes of which will influence the evaluations of the risks in the inner control of the subject on the previously made imagination of the control environment, in order to define the measures to be taken in order to change the reactions to the mistakes using different measures in order to reach the trustful mechanisms to rely on. International standards of audit– answering to the assessed risks, the checked variation of the standard implies that it maybecome necessary to change the measures of reaction to the changes in the circumstances in order to obtain enough reliable measures and activities to control the situation by means of enough auditory evidences. The auditor has responsibilities to take into consideration that largening the deadlines will cause growth of the period and the risks of the dates of events which will happen in the time interval between accountability date and the date of the conclusion made by audit, the audit is also responsible for any event taking place later in relation to the Covid-19 situation. He is responsible also for evaluation of the fact about financial information. The enterprise functioning within nowadays complex environment taking into consideration the situation of COVID 19, should consider such priority issues as the uncertainty accompanying the Covid situation, related covenants, and others which accompany the pandemic period, among them the region, the financial state of customers and dealers, liquidating and paying capacity. During the process of the risk assessments it should considered that Covid 19 pandemic greatly influenced the global economics and the separate branches such as hotels business, retail sail, tourism and others. As a result of pandemic, it is possible that the number of audit considerations and thee circumstances can modify them which can be conditioned by different circumstances and the audit will state if there are incorrectable improper conditioned due to the circumstances. The audit will make it certain there are unimprovable mistakes which apart and together are essential for the financial accountability and the auditor will conclude that they cannot acquire the proper conditioned which apart or together could be essential financial accounts or the audit will conclude that they are not able to the essential accountability. Important researches were led to assess the appeared situation and it was concluded that the COVID 19 pandemic had influenced the financial situation which showed that the specific actions and procedures became complicated.


It has long been recognised that the dielectric constant of a substance gives an important indication of its constitution, and the classical papers of Nernst and Drude giving methods for the determination of dielectric constants, have been followed by a long series of papers giving the dielectric constants of several hundreds of pure liquids and solutions. Since the publication of Debye’s dipole theory in 1912, the literature of the subject has become even more voluminous than before. In surveying the mass of data one is struck by the very large discrepancies which exist in the values obtained by different observers for any one substance, and it is very difficult to decide whether they are due to the difficulty of pre­paring and purifying the substance, differences in experimental conditions such as frequency of the applied E. M. F., or errors in the methods of measure­ment. In order to make it possible to compare the results of different observers, and to provide a fundamental basis for new measurements, it is important that the value of at least one standard liquid should be known with unquestion­able accuracy. The object of the present investigation was to provide such a value. Benzene was chosen as the standard liquid since it has been very widely used in the past, and it is used as a standard in the measurement of other physical properties.


I am honoured and privileged to be Chairman for the opening session of this Royal Society Discussion Meeting on Scientific Aspects of Irrigation Schemes. It was originally intended that Dr Howard Penman, F. R. S., was to have been the Chairman for this session, but sadly he is no longer with us. However, his valuable work over many years at the Rothamsted Experimental Station on the physics of evaporation and the determination of the Penman equation lives on and is of continuing benefit to those concerned with irrigation development throughout the world. First, I would like to stress the importance of the subject of this discussion meeting to industrial and developing countries alike, and offer the following estimates of areas under irrigation and drainage-flood protection worldwide in support of this view.
