High living standards and a comfortable modern way of life are related to an increased usage of various plastic products, yielding eventually the generation of an increased amount of plastic debris in the environment. A special concern is on microplastics (MPs), recently classified as contaminants of emerging concern (CECs). This review focuses on MPs’ adverse effects on the environment based on their bioactivity. Hence, the main topic covered is MPs’ ecotoxicity on various aquatic (micro)organisms such as bacteria, algae, daphnids, and fish. The cumulative toxic effects caused by MPs and adsorbed organic/inorganic pollutants are presented and critically discussed. Since MPs’ bioactivity, including ecotoxicity, is strongly influenced by their properties (e.g., types, size, shapes), the most common classification of MPs types present in freshwater are provided, along with their main characteristics. The review includes also the sources of MPs discharge in the environment and the currently available characterization methods for monitoring MPs, including identification and quantification, to obtain a broader insight into the complex problem caused by the presence of MPs in the environment.

Purpose To better enable communication among researchers, clinicians, and caregivers, we aimed to assess how untrained listeners classify early infant vocalization types in comparison to terms currently used by researchers and clinicians. Method Listeners were caregivers with no prior formal education in speech and language development. A 1st group of listeners reported on clinician/researcher-classified vowel, squeal, growl, raspberry, whisper, laugh, and cry vocalizations obtained from archived video/audio recordings of 10 infants from 4 through 12 months of age. A list of commonly used terms was generated based on listener responses and the standard research terminology. A 2nd group of listeners was presented with the same vocalizations and asked to select terms from the list that they thought best described the sounds. Results Classifications of the vocalizations by listeners largely overlapped with published categorical descriptors and yielded additional insight into alternate terms commonly used. The biggest discrepancies were found for the vowel category. Conclusion Prior research has shown that caregivers are accurate in identifying canonical babbling, a major prelinguistic vocalization milestone occurring at about 6–7 months of age. This indicates that caregivers are also well attuned to even earlier emerging vocalization types. This supports the value of continuing basic and clinical research on the vocal types infants produce in the 1st months of life and on their potential diagnostic utility, and may also help improve communication between speech-language pathologists and families.

Bronze drums are widely distributed, broader than the range of a nation. Therefore, the identification of each kind of drum is a basic subject, should be concerned. In determining the tribal identity of the drum, the classification of drum is the key stage, the relationship between the objective of the classification and classification criteria is the relation as shape and shadow, if there is no right criteria then the result of division will be difficult to reach the desired goal. Likewise, the criterion of the pattern on the bronze drum brought to the affirmation is the Dong Son bronze drum of the Lac Viet people. And the parallel is the affirmation of the culture, way of life, residence of the nation created the drum.

Spectral Computed Tomography

This paper demonstrates the potential of a new 3D imaging technique, Spectral Computed Tomography (sp-CT), to identify heavy elements inside materials, which can be used to classify mineral phases. The method combines the total X-ray transmission measured by a normal polychromatic X-ray detector, and the transmitted X-ray energy spectrum measured by a detector that discriminates between X-rays with energies of about 1.1 keV resolution. An analysis of the energy spectrum allows to identify sudden changes of transmission at K-edge energies that are specific of each element. The additional information about the elements in a phase improves the classification of mineral phases from grey-scale 3D images that would be otherwise difficult due to artefacts or the lack of contrast between phases. The ability to identify the elements inside the minerals that compose ore particles and rocks is crucial to broaden the application of 3D imaging in Earth sciences research and mineral process engineering, which will represent an important complement to traditional 2D imaging mineral characterization methods. In this paper, the first applications of sp-CT to classify mineral phases are showcased and the limitations and further developments are discussed.

AbstractIn this article we study the transitivity of the group of automorphisms of real algebraic surfaces. We characterize real algebraic surfaces with very transitive automorphism groups. We give applications to the classification of real algebraic models of compact surfaces: these applications yield new insight into the geometry of the real locus, proving several surprising facts on this geometry. This geometry can be thought of as a half-way point between the biregular and birational geometries.

Archaea are best known in their capacities as extremophiles, i.e. micro-organisms able to thrive in some of the most drastic environments on Earth. The protein-based surface layer that envelopes many archaeal strains must thus correctly assemble and maintain its structural integrity in the face of the physical challenges associated with, for instance, life in high salinity, at elevated temperatures or in acidic surroundings. Study of archaeal surface-layer (glyco)proteins has thus offered insight into the strategies employed by these proteins to survive direct contact with extreme environments, yet has also served to elucidate other aspects of archaeal protein biosynthesis, including glycosylation, lipid modification and protein export. In this mini-review, recent advances in the study of archaeal surface-layer (glyco)proteins are discussed.

Refined Classification

In this study, we investigate the subtle temporal dynamics of California 1999–2000 spot price series based on permutation min-entropy (PME) and complexity-entropy causality plane. The dynamical transitions of price series are captured and the temporal correlations of price series are also discriminated by the recently introduced PME. Moreover, utilizing the CECP, we provide a refined classification of the monthly price dynamics and obtain an insight into the stochastic nature of price series. The results uncover that the spot price signal presents diverse temporal correlations and exhibits a higher stochastic behavior during the periods of crisis.

Literary Legacy

Purpose: The article is devoted to the Sorbian studies work of the Italian Slavic scholar of Lusatian origin Wolfango Giusti (1901-1980) “The Folk Lusatian Serbian Song” (1926), totally unknown in Ukrainian Slavic scholars’ circles. The author of a large number of Sorbian studies publications printed in the 1920s and 1930s in the pages of Italian Slavic editions, he became a true popularizer of Lusatian culture, and his works found a special reverberation in the research papers of authoritative Sorbian scholars. W. Giusti’s name as researcher and translator has recently been more frequently mentioned in Slavistic publications, his interest in Ukrainian poetry, esp. in the 1920s, is written about. The interest in W. Giusti’s literary legacy is linked, in particular, to his being interested in T. Shevchenko’s and M. Shashkevych’s lyrics. In the research under analysis, the Italian scholar stressed that “the soul of the Lusatian people has found its best and fullest expression in their folk song”. Also mentioned by W. Giusti were Ukrainian folk songs, rich in their multi-genre samples. Results: The paper presents a classification of the most characteristic folk songs, the classification coming to be basis-providing for the Italian scholar: W. Giusti relied on authoritative research papers, including those by the scholars K. Fiedler and B. Krawc. The Italian Slavicist acquaints us with songs of love between brother and sister, love songs about the way of life of the whole people, songs resonating with the motif of fidelity. Neither has the literary scholar bypassed the issue of the neighbouring peoples’ influence experienced by Lusatian culture, particularly that of a Germanic culture, providing some examples of a “spiritual analogy” with German folk songs. W. Giusti completed his short essay by promising to offer the reader, before long, “other genres of the extremely rich Lusatian folklore”. The promise came to be fulfilled as early as the next year, in the work published under the title “Folk Lusatian Serbian Songs”. Key words: Lusatian folklore, Wolfango Giusti, folk song, motif of fidelity/infidelity, dramatic mood, classification of songs, aspects of “Wendish” folklore, Germanic influence.

The study entitled specifying prevalent utterance by separate evidence as applied study upon disagreement of fundamentalists in specifying prevalent utterance by separate evidence which might appear to be an obvious problem for the one who made aware of this disagreement particularly if he is not one of the specialists in jurisprudence. Accordingly, the main objective of this research is to identify this disagreement and to have by then insight into it through induction, analysis, and classification to find out whether it is influential disagreement when it runs into application on branches of jurisprudence or it is an only non-influential disagreement of utterance on the purpose of causing controversy along with overcoming in debate as in the case of much disagreements of fundamentalists. It is obviously that self-contained determinants in terms of numbers have been tackled so that a part of fundamentalists indicated them as nine in number, some others divided them into two sections, while others accounted them as four in number, namely mind, sense, text, and custom and by then considering remnants as branches affiliated to each other. In so far as the matter gets to this point, the researcher did not think that it should be indicated determinants as four in number and by then branches them out, but it was thought better to take trace of ancient fundamentalists in their classification. A number of results were reached by the study; some of the most important ones were: no consensus of opinion that achieved terms of being real consensus found relevant to these self-contained determinants, but all determinants have been tackled by disagreement despite the fact that some fundamentalists depicted the determinants as acquiescence in a part of their statements. Based on the results of the research, it was clearly found that it is a disagreement of utterance not disagreement of intangible content, as well as it has no influence on the classification of jurisprudence.
