Five new clavate-stigma Waltheria species endemic to Brazilian Cerrado (Malvaceae s. l., Byttnerioideae, Hermannieae)
Authors: Saunders Janice G.
Published: March 2021

Five new species are described and illustrated: Waltheria hatschbachii, W. hoehnei, both endangered for extinction, W. coriacea, W. flavovirens and W. matogrossensis. All are endemic to Brazil, in Cerrado s. l. associated with the Brazilian Plateau in N, NE, CW, and SE Brazil. Their affinities and the distinctness from W. ferruginea s. l. are discussed, and they are associated and compared with W. ferruginea s. str., from cerrado, W. brachypetala, from caatinga, W. biribiriensis and W. terminans, both from campo rupestre. The geographic distribution of all nine species is illustrated, and a new identification key for these and for the two sections of Waltheria is provided. All nine species share a clavate stigma in pin (or thrum) flowers, that morphotype given earlier as distinguishing one of three main species groups of the genus, and a new character, the ferruginea type stipitate-stellate trichome, illustrated here. Subconduplicate petals are first reported in the tribe Hermannieae, often keyed by flat petals. Waltheria is first signaled here to present the same enigmatic biogeographical pattern noted before for Triraphis (Poaceae) between Chapada dos Veadeiros, Africa and Australia. Other new taxonomic characters for Waltheria are given.
Reactions of Pentaphenylantimony and Penta-Para-Tolylanimony with Calixarene [4-t-BuC6H2OH(S-2)]4
Authors:   South Ural State University, Chelyabinsk, Russian Federation, Efremov A.N. , Sharutin V.V.
Published: March 2021

Pentaphenylantimony and penta-para-tolylantimony react with calixarene [4-t-BuC6H2OH(S-2)]4 (СArH) by way of arene elimination and formation of the [Ph4Sb]+[СAr]- × TolH (1), [p-Tol4Sb]+[CAr]- × H2O (2) ionic products with a yield up to 96%. The compound has been identified by IR spectroscopy and X-ray diffraction analysis. According to the X-ray diffraction data, compounds 1 and 2 are ionic complexes with solvate molecules of toluene (1) and water (2). The cation has a tetrahedral coordination of the antimony atom with aryl ligands at the polyhedron vertices; the anion is represented by the deprotonated form of p-tert-butylthiacalix[4]arene. The three tert-butyl groups, the phenyl ring and solvated toluene in the structure of compound 1, and two tert-butyl fragments in the structure of compound 2 are disordered over two positions. The tetrahedral coordination of antimony atoms in the cations of compounds 1 and 2 is slightly distorted. The CSbC angles deviate from the theoretical value and vary within 106.0(4)−117.7(4)° (1), 105.75(15)−112.84(15)° (2). The average Sb–C bond lengths are 2.101(3) and 2.106(4) Å in structures 1 and 2, respectively. The [СAr]- anion is in the cone conformation, the upper rim of which is represented by the tert-butyl groups in the para-position, while the lower one is represented by hydroxy groups, one of which is deprotonated. The СAr–O– bond length (1.318(4) (1) and 1.326(4) (2) Å) is less than the average value of the СAr–OH bond lengths (1.338(4) (1) and 1.343(4) (2) Å), which indicates increasing multiplicity of the bond and localization of a negative charge on the oxygen atom. Intramolecular hydrogen bonds with the neiboring O atom are observed. The H∙∙∙O distances are 2.16, 1.69, 1.77 Å in 1 and 1.92, 1.79, 1.76 Å in 2. Dihedral angles between opposite phenoxide rings are 60.64° and 87.07° (1) and 83.85° and 80.42° (2), which indicates somewhat less symmetric anion in structure 1 than in structure 2. The formation of the crystal spatial structure is due to the formation of hydrogen bonds between ions with participation of oxygen and sulfur atoms, as well as СН∙∙∙π–interactions, while the ions form chains in the crystal of compound 1, and layers in the crystal of compound 2. Complete tables of atom coordinates, bond lengths and valence angles are deposited at the Cambridge Crystallographic Data Center (No. 1850118 (1); No. 2013220 (2); deposit@ccdc.cam.ac.uk or http://www.ccdc.cam.ac.uk/data_request/cif).

Increased interest in carbofunctional organosilicon monomers (silanes) and polymers (silsesquioxanes) is associated with the fact that these compounds are promising reagents and building blocks, materials for micro-electronics, agriculture and medicine, complexones, catalysts, and efficient sorbents. Thus, functional polysilsesquioxanes surpass mineral and organic sorbents in sorption properties. Moreover, they have the highest chemical and thermal stability. Along with sorption activity carbofunctional organosilicon compounds of both monomeric and polymeric structures can possess metallochromic properties. All this paves the way for the large-scale development of analytical systems for the creation of new complex test methods for the determination, concentration and separation of metals from solutions. In the present study the functional monomer N-[3-(triethoxysilyl)propyl]acetylguanidine 1 was synthesized by the condensation reaction of 1-acetylguanidine and 3-triethoxysilyl-propylamine. Poly-N-[3-silsesquioxanyl) propyl]acetylguanidine 2 was obtained by hydrolytic polycondensation of compound 1. The composition and structure of compounds 1 and 2 were confirmed by IR and 1H NMR spectroscopy, as well as by elemental analysis. Polymer 2 was studied as a sorbent for ions of heavy metals, such as Hg (II), and noble metals Ag (I), Au (III), Rh (II), Pd (II), Pt (IV) from solutions of their salts in hydrochloric or nitric acid. For polymer 2, the values of static sorption capacities have been calculated. The latter depend on the nature of the metal and have values from 78 mg/g (for platinum) to 366 mg/g for rhodium. The graphs of the degree of metal extraction depending on the sorption time and acid concentration have been plotted. A sorption mechanism is proposed, which is realized due to the chelate interaction of the metal cation (M+) with the amide groups of compounds 1 and 2. The interaction of monomer 1, in the form of indicator paper, and polymer 2, in the powder form, with salts of the studied metals is accompanied by intense specific coloration (metallochromy). Color tables of the samples after their contact with the Ag (I), Au (III), Pd (II), Pt (IV), Rh (III), Hg (II) salts are given.
Preparation and Properties of (1-Hydroxyethylidene) Diphosphonic Acid Aminium Salts
Authors:   G.A. Razuvaev Institute of Organometallic Chemistry of the RAS,  Nizhny Novgorod, Russian Federation, Semenov V.V.
Published: March 2021

An overview of the preparation methods and properties of (1-hydroxyethylidene) diphosphonic acid aminium salts is presented. (1-Hydroxyethylidene) diphosphonic acid with monoethanolamine forms a crystalline compound, which, according to the elemental analysis and XRD data, is ternary C(CH3)(OH)[P(O)O-NH3+CH2CH2OH]3[P(O)(OH)] amine salt. A characteristic feature of the derivatives of (1-hydroxyethylidene) diphosphonic acid and tris (hydroxymethyl)aminomethane is the formation of glassy and resinous products. Their composition Н4L∙4NH2C(CH2OH)3 corresponds to 4 base molecules per 1 tetrabasic acid molecule. The addition of 4 molecules of the primary amine occurs both when the ratio of the initial reagents is 1: 4 and 1: 3. The polymer structure and the presence of strong hydrogen bonds in the Н4L∙4NH2C(CH2OH)3 compound lead to its very low solubility in organic media and good solubility in water. The solubility of Н4L∙4NH2C(CH2OH)3 in methanol is 1.8 g per 100 mL. The reaction of (1-hydroxyethylidene)diphosphonic acid with para-aminobenzoic acid leads to the formation of bis(4-carboxyphenylamine)(1-hydroxyethylidene)diphosphonate C(CH3)(OH)[P(O)(OH)O-NH3+C6H4С(О)ОН]2. In a crystal, this compound consists of the anion of the double-deprotonated (1-hydroxyethylidene)diphosphonic acid C(CH3)(OH)[P(OH)(O)O-]2 and two amine cations NH3+C6H4С(О)ОН. The tetrabasic acid binds 3 molecules of morpholine, giving tris(morpholinium)(1-hydroxyethylidene)diphosphonate H4L•3HN(CH2CH2)2O in the form of a white powder that dissolves well in water, methyl and ethyl alcohols. The solid complex of morpholine with (1-hydroxyethylidene)diphosphonic acid does not crystallize from various solvents, which may be caused by the oligomeric form of morpholine included in the molecule of the complex with H4L.

Published: March 2021

Water-holding capacity (WHC) is an important indicator of pork quality, but the existing detection methods of WHC are either expensive or time-consuming. In this study, a new method of pork WHC detection was developed by a composite film. The preparation method, mechanical properties and service life of the composite film were studied. The result showed that composite film was 0.46 ± 0.06 mm thick and had a service life of 21 days, tensile strength of 7.72 ± 0.11 MPa and the elongation at break of 28.54 ± 0.15%. Thirty groups of pork samples were randomly selected to build the model and another twenty groups were used to verify the model accuracy. Results showed that the accuracy of composite film coupled with Fisher discriminant model to detect the WHC of pork is 90%. This study demonstrates the high value of composite film as a detection tool to classify WHC of pork.
Optimized LMS algorithm for system identification and noise cancellation
Authors: Ling Qianhua , Ikbal Mohammad Asif , Kumar P.
Published: March 2021

Optimization by definition is the action of making most effective or the best use of a resource or situation and that is required almost in every field of engineering. In this work, the optimization of Least Mean square (LMS) algorithm is carried out with the help of Particle Swarm Optimization (PSO) and Ant Colony Optimization (ACO). Efforts have been made to find out the advantages and disadvantages of combining gradient based (LMS) algorithm with Swarm Intelligence SI (ACO, PSO). This optimization of LMS algorithm will help us in further extending the uses of adaptive filtering to the system having multi-model error surface that is still a gray area of adaptive filtering. Because the available version of LMS algorithm that plays an important role in adaptive filtering is a gradient based algorithm, that get stuck at the local minima of system with multi-model error surface considering it global minima, resulting in an non-optimized convergence. By virtue of the proposed method we have got a profound solution for the problem associated with system with multimodal error surface. The results depict significant improvements in the performance and displayed fast convergence rate, rather stucking at local minima. Both the SI techniques displayed their own advantage and can be separately combined with LMS algorithm for adaptive filtering. This optimization of LMS algorithm will further help to resolve serious interference and noise issues and holds a very important application in the field of biomedical science.
Is Vision C interchangeable with the modified Westergren method for the erythrocyte sedimentation rate?

Published: March 2021

Objectives

As one of the most widely used tests, the erythrocyte sedimentation rate (ESR) is a measurement of sedimentation reaction in blood samples. Although the recommended method for ESR measurement is the Westergren method, this method has some disadvantages in comparison with automated ESR systems. In this cross-sectional study, we aimed to compare Vision C with the Westergren method.

Methods

The Vision C automated ESR system and the modified Westergren method were compared using K3EDTA-containing tubes and citrated blood tubes from randomly selected 100 patients. Precision, bias, and interference calculations were performed.

Results

The mean difference between the Vision C (room temperature) and the modified Westergren method was 22.8 ± 26.6 mm/h (95% CI for the mean was 17.50–28.08 mm/h). The mean difference between the Vision C (18 °C) and the modified Westergren method was 27.4 ± 30.6 mm/h (95% CI for the mean was 21.3–33.5 mm/h). The calculated regression analysis equation was “y= 0.263 + 1.053x” and “y= −0.530 + 0.851x” for the Vision C (room temperature) and the Vision C (18 °C), respectively. The imprecision values ranged at 7.55–17.09%. According to our external quality control results, bias was 11.11 and 9.66 for the low- and high-level samples, respectively.

Conclusions

The Vision C automated ESR system has a comparable analytical performance with the modified Westergren method. The Vision C automated system may be utilized in ESR measurements with quality control evaluations. Nevertheless, temperature correction using Manley’s monogram causes an important negative bias and should be taken into consideration during the evaluation of the Vision C results.
Increased Hippocampal Excitability and Altered Learning Dynamics Mediate Cognitive Mapping Deficits in Human Aging
Authors: Diersch Nadine , Valdes-Herrera Jose P. , Tempelmann Claus , Wolbers Thomas
Published: March 2021

Learning the spatial layout of a novel environment is associated with dynamic activity changes in the hippocampus and in medial parietal areas. With advancing age, the ability to learn spatial environments deteriorates substantially but the underlying neural mechanisms are not well understood. Here, we report findings from a behavioral and a fMRI experiment where healthy human older and younger adults of either sex performed a spatial learning task in a photorealistic virtual environment (VE). We modeled individual learning states using a Bayesian state-space model and found that activity in retrosplenial cortex (RSC)/parieto-occipital sulcus (POS) and anterior hippocampus did not change systematically as a function learning in older compared with younger adults across repeated episodes in the environment. Moreover, effective connectivity analyses revealed that the age-related learning deficits were linked to an increase in hippocampal excitability. Together, these results provide novel insights into how human aging affects computations in the brain's navigation system, highlighting the critical role of the hippocampus.

SIGNIFICANCE STATEMENTKey structures of the brain's navigation circuit are particularly vulnerable to the deleterious consequences of aging, and declines in spatial navigation are among the earliest indicators for a progression from healthy aging to neurodegenerative diseases. Our study is among the first to provide a mechanistic account about how physiological changes in the aging brain affect the formation of spatial knowledge. We show that neural activity in the aging hippocampus and medial parietal areas is decoupled from individual learning states across repeated episodes in a novel spatial environment. Importantly, we find that increased excitability of the anterior hippocampus might constitute a potential neural mechanism for cognitive mapping deficits in old age.
Kobiety w kasie Mianowskiego

W 1881 r. wychowankowie Szkoły Głównej czcząc pamięć jej Rektora utworzyli „Kasę pomocy dla osób pracujących na polu naukowym im. dr. med. Józefa Mianowskiego”. W niezwykłej historii Kasy odnotowujemy nazwiska najwybitniejszych uczonych oraz twórców kultury polskiej. Po likwidacji Kasy w 1952 r., reaktywowano ją w 1990 r. Cele w swym ogólnym zarysie są od początku istnienia Kasy te same: wspieranie nauki polskiej, pomoc dla młodych naukowców w formie stypendialnej oraz wspieranie wydawnictw naukowych. Z działalnością Kasy związane są, przede wszystkim panie profesor reprezentujące różne dziedziny nauki: Maria Ossowska, Alicja Karłowska-Kamzowa, Janina Jóźwiak, Monika Haman, Barbara Kuźnicka, Joanna Schiller-Walicka, Elżbieta Smułkowa. W 1930 r. honorowym, dożywotnim członkiem Kasy im. Józefa Mianowskiego została Maria Skłodowska-Curie.
„Gdzie kilka kobiet weźmie się za sprawę…”, czyli emancypacja na przykładzie Marii Dulębianki
Authors:   Uniwersytet Jana Kochanowskiego w Kielcach, Świetlik Katarzyna , Woś Paweł ,   Uniwersytet Jana Kochanowskiego w Kielcach
Published: March 2021

Głównym celem artykułu jest przypomnienie postaci zasłużonej działaczki, artystki, feministki i patriotki, Marii Dulębianki (1862-1919), od śmierci której minęło sto jeden lat. Jednak to nie rocznica, a działania, jakich podejmowała się Dulębianka, posłużyły za główną motywację do przygotowania niniejszego artykułu. Pomimo nieprzychylnych postaw prezentowanych przez mężczyzn względem kobiet, które objawiały się m.in. w braku dostępu do edukacji na akademiach sztuk pięknych, co dotknęło artystkę personalnie, M. Dulębianka „zrzuciła patriarchalne okowy” i postanowiła walczyć nie tylko o kobiety, ale i całą narodową sprawę. Początkowo batalia ta miała charakter bardziej spontaniczny, bez konkretnego, opracowanego planu, bez organizacji, jednak to właśnie te żywiołowe działania, jak choćby zamieszczane w prasie artykuły autorstwa Dulębianki, czy uczestnictwo, a także organizacja licznych wieców, uczyniły pewnego rodzaju wyłom. Aktywność bohaterki na polu społeczno-politycznym, ale również kulturalno-oświatowym, doskonale wpisuje się w istniejący model kobiecych wyobrażeń i perspektyw na drodze ku równouprawnieniu. Próba spojrzenia na postać zasłużonej Polki przez pryzmat jej życia, zarówno publicznego, jak i prywatnego, pozwala na ukazanie pełnego wachlarza indywidualnych postaw, które cechowały Dulębiankę w celach, jakie sobie postawiła. Nawoływania nie tylko skierowane do kobiet, ale także, a może przede wszystkim, do mężczyzn o prawach płci pięknej do wykształcenia, jak i samostanowienia niejednokrotnie splatały się z hasłami równouprawnienia wszystkich warstw społecznych, w czym widziała jedyną drogę do odzyskania niepodległości.
Kontestatorki. Formy zaangażowania kobiet w ­Polsce po 1945 roku
Authors:   Uniwersytet Pedagogiczny im. KEN w Krakowie, Mikołajczyk Magdalena
Published: March 2021

Kontestacja jest synonimem sprzeciwu, najczęściej skierowanego przeciw określonego typu rozwiązaniom, ale także przeciw ideologiom, strategiom, rodzajom wdrażanych polityk, nawet przeciw obyczajom lub tradycjom. Kojarzy się, jest przedwstępem opozycyjności. Może ją sugerować wypowiedź lub zachowanie. Może stanowić zagrożenie dla ładu politycznego i prawnego lub być indyferentna. Zaangażowanie zaś stanowi najszerszy kontekst dla partycypacji politycznej, dalej zaś politycznej aktywności. Zaangażowanie polityczne jest kojarzone z udziałem protagonistów systemu politycznego, akolitów elit władzy oraz przeciwnie – może wyznaczać drugi biegun, w demokracji kojarzony z opozycją, w systemach autorytarnych z ludźmi i środowiskami wpływającymi na erozję legitymacji udzielanej systemowi, odpływ poparcia społecznego. W latach 1945-1989 szereg zmiennych politycznych i ustrojowych determinował ograniczenie możliwości swobodnych wystąpień, demonstracji postaw krytycznych. W prezentowanych badaniach staram się skupić uwagę na ekspresji niezadowolenia wyrażanej przez jednostki, zwłaszcza kobiety. Ich obecność w każdej z opozycyjnych inicjatyw była zauważalna, choć ilościowe szacunki nie dowodzą reprezentatywności tej kategorii. Przywołując ustalenia badaczek najnowszej historii Polski (wykazujących najczęściej marginalność aktywności kobiet) oraz korzystając z materiałów o charakterze biograficznym staram się wyodrębnić formy inicjatyw, charakterystyczne zachowania, słowem scharakteryzować ten rodzaj aktywności kobiet, który był przeciwieństwem politycznego konformizmu.
Kultura organizacyjna społecznych ruchów kobiet: na podstawie publicystyki „Ziemianki Polskiej” (1926-1939)
Authors:   Uniwersytet Marii Curie-Skłodowskiej w Lublinie, Maj Ewa
Published: March 2021

Czasopismo „Ziemianka Polska” miało podtytuł: „organ zrzeszeń ziemianek wszystkich ziem polskich”. Ukazywało się w Warszawie w latach 1926-1939. Hasłem przewodnim było „Z Bogiem i Narodem”. Pod względem tematycznym pismo zajmowało się zagadnieniami instytucjonalizacji ruchu kobiet z uwzględnieniem ideologii ziemiańskiej. Emanacją ruchu były organizacje jak Stowarzyszenie Zjednoczonych Ziemianek oraz struktury szczególne na przykładzie Kongregacji Ziemianek pod wezwaniem Matki Boskiej Kochawińskiej. Redakcja „Ziemianki Polskiej” upowszechniała wartości narodowe, religijne, konserwatywne. Kreowała obraz Polki-katoliczki, hołdującej tradycjonalistycznemu i zachowawczemu oglądowi świata. Funkcje informacyjne i perswazyjne realizowano z wykorzystaniem faktografii dotyczącej działalności organizacji. Obok spraw instytucjonalnych w sferze zainteresowań publicystycznych była aktywność członkiń zrzeszeń ziemiańskich. Pokazywano różne rodzaje aktywności kobiet z wyższych warstw społecznych, zamożnych, wykształconych, mających predyspozycje do pracy pro bono. Problem kultury organizacyjnej społecznych ruchów kobiet był prezentowany w ujęciu statycznym (struktura organizacyjna, statutowa działalność stowarzyszenia, program) oraz dynamicznym (inspirowanie aktywności kobiet ze środowiska ziemiańskiego). Zajęto się stopniem formalizacji działań oraz rodzajem centralizacji pracy formacyjnej. Przedstawiono grupę miękkich czynników organizacyjnych, spożytkowano wiedzę o relacjach międzyludzkich wewnątrz ruchu, o sposobach hierarchizowania członkiń zrzeszeń, o metodach zarządzania sytuacją kryzysową. Zwrócono uwagę na istnienie symboli i rytuałów organizacyjnych, mających znaczenie w procesie integrowania uczestniczek.

In a nuttshell: an analysis of thesis abstracts of Croatian university students in L2 English
Authors: Vickov Gloria , Jakupčević Eva
Published: March 2021

Abstracts are prerequisites for journal publications and conferences, as well as grant applications, which makes writing an efficient abstract a crucial and yet challenging task. This task is particularly demanding for university students who may need to write their thesis abstracts in L2 English. In order to gain insight into students’ abstract writing skills in L2 English at the academic level, the present study gives an analysis of a corpus of 100 thesis abstracts written by Croatian undergraduate and graduate students of the Faculty of Humanities and Social Sciences in Split. We have conducted an analysis of rhetorical moves in the abstracts and determined the types and frequency of the students’ errors. The results showed that the abstracts frequently lacked the basic information expected in a research abstract, such as a clear explanation of the approach or motivation for the study. Error-wise, the students struggled most with articles and prepositions. Lexical errors, e.g. the mis-selection of words (collocations), were also common, as were problems with punctuation. The identification of these weaknesses in the students’ abstract writing skills is essential for the development of teaching guidelines to be used for their prevention and elimination.
Između nacionalnoga identiteta i ideologije. Gradišće kalendar za 1946. godinu
Authors: Bacalja Robert , Ivon Katarina
Published: March 2021

U radu se analizira prvo godište Gradišće kalendara koji je pokrenuo i do svoje smrti (1973.) uređivao Ignac Horvat. Novopokrenutu se publikaciju nakon Drugoga svjetskog rata Horvat odlučuje tiskati u Hrvatskoj jer za tiskanje u Austriji nisu bili stvoreni uvjeti. Donijelo je to i stanoviti urednički izazov, s obzirom na to da su se prilike u Hrvatskoj promijenile pod utjecajem novoga državnog uređenja i komunističke ideologije. Kalendar je imao važnu ulogu u razvoju gradišćanskohrvatske književnosti i kulture u poslijeratnome razdoblju, posebice zbog društvenopovijesnoga konteksta u kojemu su se našli Hrvati u Austriji. Svojim je književnim prilozima i prilozima svojih suvremenika Ignac Horvat postavio temelj novijoj gradišćanskohrvatskoj književnosti, pritom afirmirajući niz novih imena koja su obilježila književnost u Gradišću do danas (Ana Šoretić, Jurica Čenar). Analizirajući teme iz manjinske vizure, Gradišće kalendar ponudio je prepoznatljiv kulturni imaginarij usmjeren matičnoj kulturi potvrđujući i nezaobilaznu ulogu Ignaca Horvata u očuvanju i promicanju hrvatskoga nacionalnog identiteta.
Tko je autor starofrancuskoga virelaia iz katedrale sv. Stošije u Zadru?
Authors: Levačić Patrick
Published: March 2021

Starofrancuski virelai iz 14. stoljeća, otkriven za vrijeme restauriranja korskih sjedala u zadarskoj stolnoj crkvi 1969. godine, najstariji je notni zapis svjetovne glazbe u Hrvatskoj. Notni zapis popraćen je starofrancuskim ljubavnim stihovima koje je anonimni francuski pjesnik kreirao tako da se, među ostalim, inspirirao Romanom o Ruži, remek-djelom francuskoga 13. stoljeća. Do sada su otkrivene tri verzije iste pjesme: pariška, bolonjska i zadarska. Dosadašnja istraživanja pokazala su da sve tri verzije potječu od jednoga jedinstvenog izvora. Zadarski tekst (virelai) ukazuje da je original nastao na sjeveru Francuske, točnije u Pikardiji. Cilj je rada analizirati književnu strukturu virelaia i ukazati na pojedine elemente te strukture koje se mogu sagledati iz prizme srednjovjekovne francuske lirike. Na temelju izdvojenih elemenata odgovorit ćemo kojemu se francuskom književniku može najviše približiti zadarski virelai. Naša je hipoteza da on najviše odgovara poetici srednjovjekovnoga francuskog književnika Jeana Froissarta (1337. – 1405.). On je podrijetlom iz sjeverne Francuske odnosno Pikardije, mnogo je putovao Italijom, pisao je romane po uzoru na Lancelota, a lirske pjesme kao virelai piše po uzoru na Guillaumea de Machauta te se također inspirira Romanom o Ruži. Konkretna sadržajna specifičnost koja ga neposredno povezuje sa zadarskim ljubavnim stihovima pojavljuje se preko djela Le dit du chevalier bleu.
Neki elementi mitologije i fantastike u postmodernističkoj prozi Viktora Pelevina (na primjerima tekstova Žuta strijela, Omon Ra, Čapajev i praznina, Generation Pi, Sveta knjiga vukodlaka)
Authors: Ćoso Zoran
Published: March 2021

U romanima i pripovijetkama Viktora Olegoviča Pelevina, suvremenoga ruskog pisca, mitologija i fantastika, kao elementi nekih vrlo davnih vremena, prepleteni su s modernim vremenom postsovjetske Rusije. Ti elementi, iako navodno davno ostavljeni u prošlosti, u nekim novim oblicima pojavljuju se kao nikad do kraja razjašnjeni problemi iz sfere iracionalnog, a koji realno uvjetuju život pojedinca i društva u cjelini. Svrha je ovoga rada pomoću analitičkog pristupa pokazati na izabranim književnim primjerima da Pelevin problematizira ideju kako je suvremeno društvo, iako je, nominalno, već odavno odmaklo od svijeta davnih mitova i fantazija koji se fizički ne može opipati ni racionalno obrazložiti, svejedno u stvarnosti rukovođeno tim prikrivenim i nevidljivim, često i iracionalnim, nehumanim motivatorima, a ne onima javno deklariranima i društveno prihvatljivima.

Megaproyectos y conflictos ecoterritoriales. El caso del Tren Maya
Authors: Casanova Casañas Laura
Published: March 2021

Al amparo de la globalización neoliberal, actualmente los procesos de despojo transforman de manera recurrente territorios indígenas en América Latina. En este artículo, se propone analizar la oposición que se da entre estas prácticas de acumulación por desposesión de las empresas transnacionales (ETN) y las cosmovisiones de los pueblos originarios a través del análisis de los conflictos ecoterritoriales. Tomando el concepto de Rocío Silva Santisteban, se trata de conflictos que nacen de la pugna por el uso y gestión del territorio, entendiendo territorio como concepto holístico, donde interaccionan múltiples violencias. El objetivo de este artículo será desgranar el choque entre estas dos visiones antagónicas del mundo de la mano de perspectivas como la ecología-mundo de Jason W. Moore, que permitirá leer los megaproyectos como un producto más del capitalismo que explota sistémicamente seres humanos y naturaleza al servicio de la acumulación, o el ecofeminismo, que aportará luz a la interdependencia entre territorios y cuerpos como espacios vulnerables. Asimismo, se tomará como ejemplo el caso del Tren Maya, el megaproyecto estrella del actual presidente de México, Andrés Manuel López Obrador, para evidenciar el falso desarrollo que promete la obra ferroviaria para el sureste del país en el marco de la llamada Cuarta Transformación. A través de este conflicto ecoterritorial, que ha despertado la oposición de movimientos sociales e indígenas, se plasmará este choque de visiones y se corroborará el avance de las fronteras extractivas gracias, entre otros aspectos, a la vulneración de derechos humanos como el derecho a consulta del Convenio 169 de la OIT. Por último, el artículo invitará a mirar el Tren Maya desde una mirada de las cartografías críticas, que lo interrelacionarán con proyectos mayores y que revelarán México como un país laboratorio de los tratados de comercio internacional que han propiciado la expansión de megaproyectos en el país.
Analysis and simulation on dynamics of a partial differential system with nonlinear functional responses
Authors: Jia Yunfeng
Published: March 2021

We introduce a reaction–diffusion system with modified nonlinear functional responses. We first discuss the large-time behavior of positive solutions for the system. And then, for the corresponding steady-state system, we are concerned with the priori estimate, the existence of the nonconstant positive solutions as well as the bifurcations emitting from the positive constant equilibrium solution. Finally, we present some numerical examples to test the theoretical and computational analysis results. Meanwhile, we depict the trajectory graphs and spatiotemporal patterns to simulate the dynamics for the system. The numerical computations and simulated graphs imply that the available food resource for consumer is very likely not single.
IN SEARCH OF A “POSITIVELY EXCELLENT” HERO: PRINCE MYSHKIN BY F. M. DOSTOEVSKY AND SEGELIEL BY V. F. ODOEVSKY
Authors: Sytina Yulia
Published: March 2021

The article analyzes the searches conducted by F. M. Dostoevsky and V. F. Odoevsky for a “positively excellent” hero. It compares the images of Prince Myshkin from The Idiot and the hero of the dramatic excerpt Segeliel, or Don Quixote of the XIX century. The similarity between these two characters is reflected as early as in the history of their creation. The authors hypothesize that in both cases an Easter archetype emerges behind the conscious or unconscious desire to substitute a grim and sinful character with a “positively excelent” one. Myshkin and Segeliel love the world with a compassionate, selfless and active love, but they are alien to other people, differ by their very nature and are aware of this otherness. The heroes do not accept the “earthly” hierarchy in relation to people, they are incomprehensible to others and are laughable from the point of view of “common sense.” At the same time, there are numerous differences between them. Segeliel is a spirit, but he is rational, he believes in laws and in science. Myshkin strives for a mystical experience of life. Failures lead Myshkin to humility, and Segeliel to rebellion. Dostoevsky’s hero seeks to flee from the world. Odoevsky’s hero wants to intervene in earthly affairs. Segeliel wants to remake the world without God. He does not believe in the Creator and repines against him. Segeliel’s throwings are reminiscent of the complex dialectic of good and evil, construed by rebels from Dostoevsky’s novels. At the same time, it is important to distinguish the positions of Segeliel and Odoevsky himself, who is not in complete agreement with his hero. Certain common motifs, i.e., those of childhood and foolishness for Christ, create parallels between Myshkin and Odoevsky, the character and the writer. The many intersections between the image of Segeliel, his author and the image of Prince Myshkin allow us to identify the cultural code that appears in the works of Russian writers who sought to find the earthly embodiment of truth, goodness and beauty in a rough physical shell, inevitably hindered by original sin.
EXCESSIVE DRINKING AS A MORAL TRANSGRESSION IN THE WORK OF F. M. DOSTOEVSKY
Authors: Kuikina Evgeniia
Published: March 2021

The article studies the topic of excessive drinking in the works of F. M. Dostoevsky in the light of the tradition of the ancient feast, or symposium. The wine offered at a symposium did not merely incline people to philosophical conversations and discussions about eternal questions, but also revealed the inner human essence, thoughts and intentions. There is ancient understanding of wine as a means of forgetting sorrows and attaining temporary joys. Excessive drinking is associated with the ancient Dionysian idea — excessive drinking at the festival of Dionysus, and the concept of metamorphosis — people lose their human essence and begin to resemble animals. In the fates of the heroes of Dostoevsky’s Poor Folk, Humiliated and Insulted, Notes from Underground, Crime and Punishment, Demons, The Brothers Karamazov, the ancient tradition is combined with the Christian understanding of a feast as reveling, and amusements at a feast, and excessive drinking as a moral transgression. On the pages of Dostoevsky’s magazine Citizen excessive drinking is equated to a serious illness, a flood, a fire, an enemy invasion, that is, to a catastrophe that affects the Russian people. The ancient tradition allows to reveal additional meanings in Dostoevsky’s interpretation of the topic of excessive drinking.
Current Prescription Opioid Misuse and Suicide Risk Behaviors Among High School Students
Authors: Wilkins Natalie J. , Clayton Heather , Jones Christopher M. , Brown Melissa
Published: March 2021

BACKGROUND AND OBJECTIVES:

In previous studies, researchers have reported that youth with a lifetime history of prescription opioid misuse (POM) are at an increased risk for suicidal ideation, planning, and attempts. In this study, we investigate whether the association between youth POM and suicide outcomes differs by recency of POM (ie, none, past, or current misuse).

METHODS:

In this report, we use data from the 2019 Youth Risk Behavior Survey to examine associations between recency of POM (current POM, past POM, and no POM) and suicide risk behaviors among US high school students.

RESULTS:

After controlling for demographics, alcohol, and other drug use, both current POM and past POM were significantly associated with all suicide risk behaviors compared with no POM. Students who reported current POM had the highest adjusted prevalence ratios (aPRs) for suicidal ideation (aPR: 2.30; 95% confidence interval [CI] 1.97–2.69), planning (aPR: 2.33; 95% CI 1.99–2.79), attempts (aPR: 3.21; 95% CI 2.56–4.02), and feeling sad or hopeless (aPR: 1.59; 95% CI 1.37–1.84). Students who reported current POM also were significantly more likely than youth who reported past POM to report that they had seriously considered attempting suicide, made a suicide plan, and attempted suicide.

CONCLUSIONS:

Although POM, particularly current POM, is associated with increases in the risk for suicide-related behaviors and experiences of youth, comprehensive prevention approaches that address the intersections between suicide and POM provide a promising path forward for addressing these public health challenges among youth.

The present study evaluated the carbapenem resistance mechanisms of Klebsiella pneumoniae strains isolated in two Greek tertiary teaching hospitals and their susceptibility to currently used and novel antimicrobial agents.

Forty-seven carbapenem resistant K. pneumoniae strains were collected in G. Papanikolaou and Ippokrateio hospital of Thessaloniki between 2016 and 2018. Strain identification and antimicrobial susceptibility was conducted by Vitek 2 system (Biomérieux France). Susceptibility against new antimicrobial agents was examined by disk diffusion method. Polymerase chain reaction (PCR) was used to detect blaKPC, blaVIM, blaNDM and blaOXA-48 genes.

The meropenem–EDTA and meropenem–boronic acid synergy test performed on the 24 K. pneumoniae strains demonstrated that 8 (33.3%) yielded positive for metallo-beta-lactamases (MBL) and 16 (66.6%) for K. pneumonia carbapenemases (KPC) production. Colistin demonstrated the highest in vitro activity (87.7%) among the 47 K. pneumoniae strains followed by gentamicin (76.5%) and tigecycline (51%). Among new antibiotics ceftazidime/avibactam showed the highest sensitivity (76.6%) in all strains followed by eravacycline (66.6%). The blaKPC gene was present in 30 strains (63.8%), the blaNDM in 11 (23.4%) and the blaVIM in 6 (12.8%). The blaOXA-48 gene was not detected.

Well established antimicrobial agents such as colistin, gentamicin and tigecycline and novel antibiotics like ceftazidime/avibactam and eravacycline can be reliable options for the treatment of invasive infections caused by carbapenem-resistant K. pneumoniae.
Interactions between immune system and the microbiome of skin, blood and gut in pathogenesis of rosacea
Authors: Joura Marie Isolde , Brunner Alexandra , Nemes-Nikodém Éva , Sárdy Miklós , Ostorházi Eszter
Published: March 2021

The increasingly wide use of next-generation sequencing technologies has revolutionised our knowledge of microbial environments associated with human skin, gastrointestinal tract and blood. The collective set of microorganisms influences metabolic processes, affects immune responses, and so directly or indirectly modulates disease. Rosacea is a skin condition of abnormal inflammation and vascular dysfunction, and its progression is affected by Demodex mites on the skin surface. When looking into the effects influencing development of rosacea, it is not only the skin microbiome change that needs to be considered. Changes in the intestinal microbiome and their circulating metabolites, as well as changes in the blood microbiome also affect the progression of rosacea. Recent research has confirmed the increased presence of bacterial genera like Acidaminococcus and Megasphera in the intestinal microbiome and Rheinheimera and Sphingobium in the blood microbiome of rosacea patients. In this review we discuss our current knowledge of the interactions between the immune system and the skin, gut and blood microbiome, with particular attention to rosacea diagnostic opportunities.

Authors: Hajdu László , Dávid Balázs , Krész Miklós
Published: March 2021

Because of the wide variety of possible application fields and the spread of smart devices, the research of wireless sensor networks has become an increasingly important area in the last decade. During the design of these networks, several important aspects have to be considered, for example the lifetime of the network, expected battery usage, or robustness of the installed system. In this paper a simulation environment is introduced that enables the testing of different information spreading methods on the network and provides suggestions for gateway placements with different objectives.
DILEMMA AND PATH SELECTION OF COLLEGE SPORTS RESOURCES INTO THE PUBLIC SERVICE SYSTEM OF NATIONAL FITNESS IN THE NEW ERA
Authors: Liu Zhuan
Published: March 2021

ABSTRACT With the improvement of people's yearning for a healthy and beautiful life, national fitness has become a hot word in academic circles. Combining Data Envelopment Analysis (DEA) and the Tobit technology, this paper constructs the evaluation model of college sports resource efficiency based on the DEA Tobit model. Based on the establishment of the input-output index system of college sports resources, the model achieves the effect of accurate analysis on the allocation efficiency of university sports resources. Taking 10 universities in a city as experimental objects, the model is verified. The verification shows that the three efficiency indexes of STU University and IPE University in group M are all 1, which shows that the resource allocation is more reasonable; the comprehensive efficiency of Ju university is low, and the sports resources investment is excessive; in group n, except for the EU University, the efficiency of other colleges and universities is lower than the pass line. It can be concluded that there are problems such as excessive input of sports resources and low output rate in Colleges and universities of a city. Therefore, colleges and universities in a city should make full use of the existing resources, enhance their social sports guidance force, while improving the publicity of national fitness. This study has high reference significance for the path selection of national fitness integration in Colleges and Universities.
