EDUCATIONAL ISSUES ON THE PAGES OF POLISH JOURNALES IN LVIV (LATE XIX – EARLY XX CENTURIES)
Authors: LAZURKO Lidiia 
Published: May 2024

The purpose of the study is to show how Lviv cinema was covered in the Polish scientific press. XIX – beginning 20th century issues of the history of education in the eastern territories of the Polish-Lithuanian Commonwealth. Research methodology is based on the principles of historicism, systematicity, scientificity, verification, authorial objectivity using general scientific and special historical methods. The scientific novelty of the research lies in the fact that, for the first time, based on the materials of the studies included in the Polish historical journals of Lviv at the turn of the 19th and 20th centuries, an attempt was made to identify the dominant themes in the study of the history of education in the borderlands of the Polish-Lithuanian Commonwealth. Conclusions. This led to the creation of the first Polish Professional Historical Society (1886) and the emergence of a number of amateur and professional journals in the field of history (“Przewodnik Naukowy i Literacki”, “Kwartalnik Historyczny”, “Ruś”). It is shown that a significant place in these publications was occupied by Ukrainian issues, which were covered in various formats – from popular science research and essays in cryptohistorical publications to intelligence, source materials and reviews, which formed the basis of content in specialized projects. The study of publications on educational topics made it possible to identify a number of topics, among which a prominent place was occupied by issues of education in the Ukrainian territory of the Commonwealth. It is shown that historical investigations of educational publications were designed to arouse interest in learning about the past, which Polish researchers perceived as an integral part of the legacy of the destroyed Commonwealth, and for many of them were a small homeland and foster patriotic feelings. It has been established that a notable feature of popular science journals was the romanticization of the past and the interpretation of education and historical memory as an outpost for the preservation of Polish cultural traditions in these lands. With the professionalization of historical studies, intelligence became more professional, and the place of legends was taken by scientific elaborations of sources based on the application of a critical method, which translated the interpretation of education into the spread of Western culture in the east.
JOURNALISM OF MYRON КORDUBA ON PAGES OF «HROMADSKA DUMKA»
Authors: BATIUK Taras 
Published: May 2024

The purpose of the article is to analyze the journalism of M. Korduba on the pages of the Lviv newspaper «Hromadska Dumka». The research methodology is based on a combination of principles (historicism and objectivity) and methods (general scientific and special-historical) of scientific work. The scientific novelty of the article consists in an attempt to comprehend the phenomenon of historian’s journalistic heritage in «Hromadska Dumka» («Public Opinion»).Conclusions. The journalism of M. Korduba on the pages of «Hromadska Dumka» was devoted to the comprehensive analysis of the most important issues for Ukrainians of national life during the early 1920s. First of all, it was a difficult problem to overcome a wide range of consequences of the defeat of the national struggle in the Galician and Transdniestrian lands. The historian urges against national self-humiliation, showing the subjective and objective reasons for Ukrainians to lose their own statehood. He proposes to make the right conclusions from defeat and move further to gaining independence. M. Korduba convinces that Ukrainians have the fate of their own hands, soberly assess the unfavorable foreign political situation, and urges to step aside from internal conflicts and to give a clear signal to the western countries about the presence of a consolidated vision of the national perspective. As M. Korduba claims, only unity of the Ukrainian nation will gain the respect of European partners and will establish constructive relations. This optimism also marked articles on the relations of Ukrainians with their eternal rivals – the Polish and Russians. He stresses at the need to seek consensus with the neighbors by establishing an equitable national dialogue and rejecting the policy of escalating national atrocities. In general, the analyses of M. Korduba‘s writings prove him to be a talented publicist, who was able to diagnose the problems of Ukrainians of his times and offer effective recipes for national recovery.

Published: May 2024

Gruppearbejde er en velkendt arbejdsform i grundskolen, der både har læringsmæssige muligheder og begrænsninger. Det gælder ikke mindst, når elever skal samarbejde om at udvikle fælles idéer, hvor nogle elever let overtager styringen, mens andre kan have svært ved at blive hørt. I denne artikel analyserer vi videoobservationer af 5. og 6. klasse elevers brug af fysiske samtalekort og det digitale redskab Google Jamboards til at understøtte deres kreative samarbejdsprocesser. Vi tager teoretisk afsæt i en forståelse af gruppearbejde som dialogisk rum for divergent og konvergent idéudvikling, der giver elever mulighed for at åbne, udvide og uddybe deres fælles forståelser. Samtidig er vi optaget af, hvordan de forskellige redskaber kan bidrage til at rammesætte dialog ved at tilbyde eleverne roller og undersøgende spørgsmål. Vores fund peger på, at Google Jamboards er velegnet til at støtte forberedelse og skabe overblik over ideer, mens samtalekort både kan styrke elever, som har svært ved at tage roller og byde ind i gruppearbejdsformen, og virke som hjælp til at holde det fælles dialogiske rum åbent.

Authors: Yang Guanyu , Wang Pengfei , Yin Yue , Qu Huan , Zhao Xin , Jin Xiaogao , Chu Qinjun 
Published: May 2024

Purpose
To compare the impact of erector spinae plane block (ESPB) and paravertebral block (PVB) on the quality of postoperative recovery (QoR) of patients following laparoscopic sleeve gastrectomy (LSG).

Methods
A total of 110 patients who underwent elective LSG under general anesthesia were randomly assigned to receive either ultrasound-guided bilateral ESPB or PVB at T8 levels. Before anesthesia induction, 40 mL of 0.33% ropivacaine was administered. The primary outcome was the QoR-15 score at 24 hours postoperatively.

Results
At 24 hours postoperatively, the QoR-15 score was comparable between the ESPB and PVB groups (131 (112–140) vs. 124 (111–142.5), P = 0.525). Consistently, there was no significant difference in QoR-15 scores at 48 hours postoperatively, numerical rating scale (NRS) pain scores at any postoperative time points, time to first ambulation, time to first anal exhaust, postoperative cumulative oxycodone consumption, and incidence of postoperative nausea and vomiting (PONV) between the two groups (all P > 0.05). No nerve block-related complications were observed in either group.

Conclusion
In patients undergoing LSG, preoperative bilateral ultrasound-guided ESPB yields comparable postoperative recovery to preoperative bilateral ultrasound-guided PVB.
The Impact of an Earthworm Digestion on the Chemical Compositions of Various Clay Minerals from Soils
Authors: Semhi Khadija , Clauer Norbert 
Published: May 2024

Aims: The impact of living organisms activities in soils may generate various chemical and mineralogical changes. The objective of this study is to estimate the impact of earthworms on the chemistry of soil minerals such as the clay minerals.
Study Design: An experiment was carried out integrating earthworms and clay minerals. The modifications due to this interaction between minerals and organic matter induced by earthworms’ digestion are discussed.
Place and Duration of Study: Institut des Sciences de la Terre et de l’Environnement (UdS/CNRS), Université de Strasbourg, Strasbourg, France. Eight weeks of experiment for each type of clay.
Methodology: The earthworm Lumbricus terrestris was used for digestion of illite and various smectite-type minerals, with or without peat moss, during a laboratory experiment at a constant temperature of 20°C during 8 weeks and under artificial 12 hour-light and 12 hour-dark cycles, for each digestion cycle.
Results: The chemical elements extracted from smectites by the earthworm digestion appear to be mineral dependent. The behavior of K and radiogenic 40Ar is more dictated by the type of digested mineral than by the digestion process itself. The 87Sr/86Sr ratio of the acid leachates of the nontronite and peat mixture, before and after digestion, suggests that half of the digested matter corresponds to the digestive action of the earthworms, with the second half resulting from food. Digested clay material represents up to 30% and the peat moss the remainder of the mixtures.
Conclusion: This study highlights the role of organic compounds generated by earthworms activities in transfer of elements to surface waters and soil fluids.

Published: May 2024

Aims: To determine the pattern of mental health presentation and outcomes among patients accessing psychotherapy services in a primary health care centre.
Study Design: This is a cross sectional descriptive study with mix qualitative and quantitative methods.
Methodology: The quantitative method used retrospective review of records of 157 new clients who accessed psychotherapy services between January 2022 and December 2023 at Port Loyola health centre in Belize city. The qualitative method used in-depth interviews of 20 patients randomly selected from the clinic registers. Factors associated with treatment outcomes (discharged/ dropped out) were determined using bivariate analysis with chi-square test and p value < 0.05 was considered statistically significant. The qualitative data was analysed using content analysis and the result organized into themes.
Results: Depressive episodes (51%) and anxiety disorder (33%) were the most frequent diagnosis. Most patients (40%) were referred by other health workers, followed by self- referral (20.5%). Sixty-nine (43.8%) of the clients were discharged [ those who successfully completed planned psychotherapy intervention], 11(15%) still in the program, 45(28.8%) dropped out and 19(12.3 %) were referred for further mental health services. Discharge was significantly associated with increased age, number of follow up visits, diagnosis and being employed, while drop out was associated with low level of education. Confidence in the service providers, insight, stigma and socioeconomic factors also determined treatment outcomes.
Conclusion: The study supported the existing literature advocating for the integration of psychotherapy into primary health care identified as the most viable way of closing the treatment gap and ensuring that people get the mental health care they need.
First identification of tannin‐binding proteins in saliva of Papio hamadryas using MS/MS mass spectrometry
Authors: Mau Marcus , de Almeida André Martinho , Coelho Ana Varela , Südekum Karl‐Heinz 
Published: April 2011

AbstractHamadryas baboons possess salivary proline‐rich proteins (PRP), as indicated by the presence of pink‐staining protein bands using 1D SDS gel electrophoresis and Coomassie R250 staining. The ability of these protein bands to interact with tannic acid was further examined. In a tannin‐binding assay using 5 µg tannic acid mixed with hamadryas whole saliva, we recently found four distinct protein bands of apparently 72, 55, 20, and 15 kDa that were precipitated during the experiments. In this work, we were able to identify these protein bands in a follow‐up analysis using MS/MS mass spectrometry after excising such bands out of air‐dried gels. Albumin and α‐amylase were present in the tannic acid–protein complexes, with albumin already known to nonspecifically interact with a great diversity of chemical compounds. More interesting, we also identified a basic PRP and a cystatin precursor protein. This was the first successful attempt to identify a PRP from precipitated tannin–protein complexes in hamadryas baboons using MS/MS mass spectrometry. On the other hand, the role of cystatins in tannin binding is not yet well understood. However, there are recent reports on cystatin expression in saliva of rats responding to astringent dietary compounds. In conclusion, the follow‐up data on tannin‐binding proteins present in salivary secretions from hamadryas baboons adds important knowledge to primate physiology and feeding ecology, in order to shed light on the establishment and development of food adaptations in primates. It also demonstrates that tannin binding is characteristic for PRP, but might not be restricted to this particular group of proteins in primate species. Am. J.

The Nitrosocarbonyl Hetero‐Diels–Alder Reaction as a Useful Tool for Organic Syntheses
Authors: Bodnar Brian S. , Miller Marvin J. 
Published: April 2011

AbstractOrganic transformations that result in the formation of multiple covalent bonds within the same reaction are some of the most powerful tools in synthetic organic chemistry. Nitrosocarbonyl hetero‐Diels–Alder (HDA) reactions allow for the simultaneous stereospecific introduction of carbon–nitrogen and carbon–oxygen bonds in one synthetic step, and provide direct access to 3,6‐dihydro‐1,2‐oxazines. This Review describes the development of the nitrosocarbonyl HDA reaction and the utility of the resulting oxazine ring in the synthesis of a variety of important, biologically active molecules.
Homo‐ and hetero‐stereocomplexes of substituted poly(lactide)s as promising biodegradable crystallization‐accelerating agents of poly(L‐lactide)
Authors: Tsuji Hideto , Yamamoto Satomi , Okumura Ayaka 
Published: April 2011

AbstractAccelerated crystallization of poly(L‐lactide) (PLLA) homo‐crystallites occurred in the presence of poly(L‐2‐hydroxybutyrate) [P(L‐2HB)], poly(D‐2‐hydroxybutyrate) [P(D‐2HB)], and the mixture of P(L‐2HB) and P(D‐2HB) [P(L‐2HB)/P(D‐2HB)]. The accelerating effect of incorporated polymers decreased in the following order: P(L‐2HB)/P(D‐2HB) > P(D‐2HB) > P(L‐2HB) > none, for heating and isothermal crystallization for Tc of 130 and 135°C and P(D‐2HB) > P(L‐2HB)/P(D‐2HB) > none > P(L‐2HB), for cooling. The P(L‐2HB)/P(D‐2HB) homo‐stereocomplex (HMSC) crystallites, P(D‐2HB)/PLLA hetero‐stereocomplex (HTSC) crystallites, and P(L‐2HB) or P(D‐2HB) homo‐crystallites are found to be promising biodegradable nucleating agents for PLLA homo‐crystallization. The P(L‐2HB)/P(D‐2HB) HMSC crystallites are most effective during isothermal crystallization and nonisothermal crystallization with heating, whereas the P(D‐2HB)/PLLA HTSC crystallites are most effective during nonisothermal crystallization with cooling from the melt. In addition to the nucleating effect, the plasticizing effect of free P(2HB) chains increases both G and the PLLA spherulite number per unit mass. These effects result in accelerated crystallization of PLLA homo‐crystallites. © 2011 Wiley Periodicals, Inc. J Appl Polym Sci, 2011.

AbstractThe improvement and modeling of a process for the supply of the volatile aromatic hydrocarbon, styrene, to a fermentor for increased biomass production of the medium chain length polyhydroxyalkanoate (mcl‐PHA) accumulating bacterium Pseudomonas putida CA‐3 was investigated. Fed‐batch experiments were undertaken using different methods to provide the styrene. Initial experiments where styrene was supplied as a liquid to the bioreactor had detrimental effects on cell growth and inhibited PHA polymer accumulation. By changing the feed of gaseous styrene to liquid styrene through the air sparger a 5.4‐fold increase in cell dry‐weight was achieved (total of 10.56 g L−1) which corresponds to a fourfold improvement in PHA production (3.36 g L−1) compared to previous studies performed in our laboratory (0.82 g L−1). In addition this final improved feeding strategy reduced the release of styrene from the fermentor 50‐fold compared to initial experiments (0.12 mL total styrene released per 48 h run). An unstructured kinetic model was developed to describe cell growth along with substrate and oxygen utilization. The formation of dispersed gas (air) and liquid (styrene) phases in the medium and the transfer of styrene between the aqueous and dispersed liquid droplet phases was also modeled. The model provided a detailed description of these phase transitions and helped explain how the feeding strategy led to improved process performance in terms of final biomass levels. It also highlighted the key factors to be considered during further process improvement. Biotechnol. Bioeng. 2011;108: 2447–2455. © 2011 Wiley Periodicals, Inc.

AbstractStereoselective syntheses of 1,6‐bis(tributylstannyl)hexa‐1,3,5‐trienes, 1,8‐bis(tributylstannyl)octa‐1,3,5,7‐tetraenes, and 1,10‐bis(tributylstannyl)deca‐1,3,5,7,9‐pentaenes with various methylation patterns were achieved based on stereocomplementary CC bond‐forming reactions. All‐Eisomers resulted from Ramberg–Bäcklund rearrangements of distannylated diallyl‐, allylpentadienyl‐, or bis‐ (pentadienyl)sulfones. Mono‐Z‐configured 1,ω‐bis(tributylstannyl)‐1,3,5‐polyenes emerged from (Sylvestre–)Julia olefinations of Bu3Sn‐substituted enals or dienals with Bu3Sn‐substituted allyl or pentadienyl benzothiazolylsulfones. Related Ramberg–Bäcklund approaches provided all‐E‐1‐bromo‐6‐(tributylstannyl)hexa‐1,3,5‐triene but not all‐E‐1‐(tetramethyldioxaborolanyl)‐6‐(tributylstannyl)hexa‐1,3,5‐triene.
Metal‐Binding Properties of an Hpn‐Like Histidine‐Rich Protein
Authors: Zeng Yi‐Bo , Yang Nan , Sun Hongzhe 
Published: April 2011

AbstractThe Hpn‐like protein (Hpnl), a histidine‐ and glutamine‐rich protein, is critical for Helicobacter pylori colonization in human gastric muscosa. In this study, the thermodynamic properties of NiII, CuII, CoII, and ZnII toward Hpnl were studied by isothermal titration calorimetry (ITC). We found that Hpnl exhibits two independent binding sites for NiII as opposed to one site for CuII, CoII, and ZnII. Protease digestion and chemical denaturation analysis further revealed that NiII confers a higher stability upon Hpnl than other divalent metal ions. The potential NiII binding sites are localized in the His‐rich domain of Hpnl as confirmed by mutagenesis in combination with modification of histidine residues of the protein. We also demonstrated that the single mutants (H29A and H31A) and tetrameric mutant (H29‐32A) cut nearly half of the binding capacity of Hpnl towards nickel ions, whereas other histidine residues (His30, 32, 38, 39, 40, and 41) are nonessential for nickel coordination. Escherichia coli cells that harbored H29A, H31A, and H29‐32A mutant genes exhibited less tolerance toward high concentrations of extracellular nickel ions than those with the wild‐type gene. Our combined data indicated that the conserved histidine residues, His29 and His31 in the His‐rich domain of Hpnl, are critical for nickel binding, and such a binding is important for Hpnl protein to fulfill its biological functions.
