Research of microstructure and microbiological indicators of pasta products from non-traditional raw materials

Modern trends in the development of pasta production are based on the use of starch-containing raw materials for the production of medicinal and preventive pasta products. In this connection, an important observation is the state of protein and starch in pasta flour, which can be achieved by electron microscopy of the microstructure of macaroni products. Therefore, the study of microstructures and microbiological indicators of pasta from non-traditional raw materials will be relevant. The practical value of the research is characterized by improved consumer properties of pasta made from non-traditional raw materials. The novelty of the research is the development of scientific and technological bases for the production of pasta from non-traditional polycereal raw materials. The results obtained: the analysis of the obtained electronic micro-drawings showed that the microstructure of pasta from non-traditional raw materials corresponds to the standards in comparison with the control sample. The following types of mycotoxins were found in pasta from non-traditional raw materials in permitted quantities: aflatoxin B1, aflatoxin M1, zearalenone, deoxynivalenol, ochratoxin A, fumonisin, patulin, T-2. For example, the amount of zearalenone (mg/kg): in pasta according to recipe No. 1 – 0.0637, according to recipe No. 2 – 0.0251 and according to recipe No. 3 – 0.0758; in flour raw materials – according to recipe No. 1 – 0.1485, according to recipe No. 2 – 0.0261 and according to recipe No. 3 – 0.2.

The approach of the Constitutional Court of the Republic of Croatia towards the protection of the right to a healthy environment

This paper analyzes provisions of the Croatian Constitution related to environmental protection, as well as their application in the case law of the Constitutional Court of the Republic of Croatia. The main aim is to examine whether the Constitutional Court considers Croatian Constitution as prescribing the right to a healthy environment although it only explicitly prescribes the right to a healthy life. The paper shall also explore the Constitutional Court’s interpretation of other environmental provision that are enshrined in the Croatian Constitution. For the purposes of writing this paper, 94 decisions of the Constitutional Court containing the word ‘human environment’ were examined. However, the paper dealt in detail with only those decisions that explicitly referred to the application of environmental provisions of the Constitution. The paper ends with conclusions which can be drawn from the case law of the Constitutional Court with an important observation that the conclusion concerning the constitutional protection of the right to a healthy environment in Croatia unfortunately cannot be deduced due to the extreme lack of cases in which applicants call for protection of this right in their constitutional complaints.

Part VIII Compliance, Implementation, and Effectiveness, Ch.57 Effectiveness

This chapter introduces some key concepts: what international regimes are; how to measure their effectiveness (the dependent variable); how this can be explained (independent variable); and the severe methodological challenges associated with answering these questions. Two main explanatory perspectives are introduced: the nature of the problem dealt with by the regime and its problem-solving ability. The chapter then surveys some key general findings that have emerged from the study of the effectiveness of international environmental regimes. Perhaps the most important finding is that although most international regimes that have been studied have had some effect on the problems they address, they have very rarely been able—if at all—to solve them fully. Another important observation is the sizeable variation among regimes in their problem-solving ability. The chapter presents empirical examples to illustrate how effectiveness can be measured and explained in practice. Most attention is given to the global climate regime, given its prominence on the international agenda. Viewed from a problem-solving perspective, however, the climate regime emerges as a low-effectiveness regime. This is briefly contrasted with the highly successful international ozone regime, as well as a regime that is very hard to measure in terms of effectiveness due to the deep and divisive conflicts over values, namely, the international whaling regime.

An Observation on Distribution of Prime Numbers

In this research first, a sequence of properties called delta is assigned to each prime number and then examined. Deltas are only dependent on the distribution of prime numbers, so the results obtained for the delta distribution can be considered as a proxy for the distribution of prime numbers. The first observation was that these properties are not unique and different prime numbers may have the same value of delta of a given order. It was found that a small number of deltas cover a large portion of prime numbers, so by recognizing repetitive deltas, the next prime numbers can be predicted with a certain probability, but the most important observation of this study is the normal distribution of deltas. This research has not tried to justify the obtained observations and instead of answering the questions, it seeks to ask the right question.

The first Russian educational books on the French language, printed word and oral instruction

Данная статья посвящена анализу первых учебных книг, заложивших основу для дальнейшего развития учебного книгоиздания по вопросам изучения французского языка в России. Проанализированы наиболее известные первые учебники по французскому языку: «Новая францусская грамматика…» В.Е. Теплова, «Французская азбука» А. де Лави, «Наставление как по-французски…» Я. Сигезбека, «Французская азбука» Академии наук, «Новый французский словарь» П.И. Богдановича и др. Автор приходит к выводу, что все учебники французского языка рассматриваемого периода выступают своеобразным «зеркалом», отражающим прогресс, имевший место в российской педагогической мысли. Важным наблюдением признается тот факт, что многие французские азбуки, целевой аудиторией которых выступали учащиеся гимназий, приобретали популярность среди изучавших французский язык самостоятельно. Иными словами, они переходили в разряд самоучителей, в значительной степени расширяя тем самым их функциональную характеристику. The article is devoted to the analysis of the first educational books that laid the foundation for the further development of educational publishing on the study of the French language in Russia. The most famous first textbooks on the French language are analyzed: «New French grammar ...» by V. Ye. Teplov, «French alphabet» by A. de Lavi, «Manual...» by J. Sigesbek, «French alphabet» by the Academy of Sciences, «New French Dictionary» by PI Bogdanovich, etc. The author comes to the conclusion that all French textbooks of the period under review act as a kind of ‘mirror’ which reflects the progress that took place in Russian pedagogical thought. An important observation is the fact that many French alphabets, aimed for students, gained popularity among those who studied French on their own. In other words, they passed into the category of self-instruction manuals, thereby significantly expanding their functional characteristics.

Personogenesis Through Imitating Human Behavior in a Humanoid Robot “Alter3”

In this study, we report the investigations conducted on the mimetic behavior of a new humanoid robot called Alter3. Alter3 autonomously imitates the motions of a person in front of it and stores the motion sequences in its memory. Alter3 also uses a self-simulator to simulate its own motions before executing them and generates a self-image. If the visual perception (of a person's motion being imitated) and the imitating self-image differ significantly, Alter3 retrieves a motion sequence closer to the target motion from its memory and executes it. We investigate how this mimetic behavior develops interacting with human, by analyzing memory dynamics and information flow between Alter3 and a interacting person. One important observation from this study is that when Alter3 fails to imitate a person's motion, the person tend to imitate Alter3 instead. This tendency is quantified by the alternation of the direction of information flow. This spontaneous role-switching behavior between a human and Alter3 is a way to initiate personality formation (i.e., personogenesis) in Alter3.

The soundscape of the Trevi fountain in Covid-19 silence

This paper is devoted to the analyses of sound-scape at fontana di Trevi in Rome (Italy) with the aim to compare its characteristics during the Italian lockdown due to the (Sars-COV2) Covid-19 sanitary emergency and its characteristics before and after such time. The lockdown has represented an exceptional environment due to the silence everywhere, never occurred in centuries, offering the opportunity to recognize the “signature” of the sound emitted by the famous Fontana di Trevi and recognize how it interacts with other features. The signature is important for preservation issues and cultural heritage. The soundscape was documented in a field survey by means of hand held microphones, which acquired simultaneously the acoustic wavefield all around the fountain. We find that the spectral content depends on the microphone location, revealing a very complex wavefield, showing strong amplitudes during the lockdown well below 1kHz and a frequency band extending up to 10kHz. In a time period far from the lockdown, we evidence an additional frequency band around 700-1kHz, which not simply adds to the previous spectrum, but acts as a synchronization mechanism. The important observation is that the Covid-19 silence let emerge sounds that had been there for centuries, and afforded us the possibility to document them in order to study objectively a “soundprint”. Moreover, we studied the spatialization characteristics of the soundfield.

Improved Ramsey-type results for comparability graphs

Several discrete geometry problems are equivalent to estimating the size of the largest homogeneous sets in graphs that happen to be the union of few comparability graphs. An important observation for such results is that if G is an n-vertex graph that is the union of r comparability (or more generally, perfect) graphs, then either G or its complement contains a clique of size $n^{1/(r+1)}$ .This bound is known to be tight for $r=1$ . The question whether it is optimal for $r\ge 2$ was studied by Dumitrescu and Tóth. We prove that it is essentially best possible for $r=2$ , as well: we introduce a probabilistic construction of two comparability graphs on n vertices, whose union contains no clique or independent set of size $n^{1/3+o(1)}$ .Using similar ideas, we can also construct a graph G that is the union of r comparability graphs, and neither G nor its complement contain a complete bipartite graph with parts of size $cn/{(log n)^r}$ . With this, we improve a result of Fox and Pach.
