Objectives

In this study, we determined the gastroprotective and ulcer-healing effects of extracts (aqueous and methanolic) of Nauclea pobeguinii stem-back.

Methods

Gastroprotective and healing activity were evaluated following a HCl/ethanol and an indomethacin-induced acute ulcers models; acetic acid, pylorus-ligature, pylorus ligature/histamine and pylorus ligature/acetylcholine-induced chronic ulcers models.

Results

It emerges from this study that, at 100, 200 and 400 mg/kg, the extracts significantly reduced the various ulceration parameters. Compared to negative control male rats, the aqueous (100 mg/kg) and methanolic (400 mg/kg) extracts of Nauclea pobeguinii inhibited the ulcers induced by HCl/ethanol by 80.76 % and 100 % respectively, as well as ulcers induced by indomethacin by 88.28 % and 93.47 % respectively. Animals that received 200 mg/kg of both extracts showed a significant reduction in the levels of monocytes, lymphocytes, nitric oxide, MDA and a significant increase in the activities of SOD and catalase. Histological analysis showed repaired mucous epithelium at all doses of both extracts. Aqueous and methanol extracts inhibited ulceration indices by 89.33 % and 88.53 % for pylorus ligature, 83.81 % and 61.07 % for pylorus ligature/acetylcholine and 87.29 % and 99.63 % for pylorus ligature/histamine respectively. Both extracts protected the stomach lining with percentages inhibition of 79.49 % and 81.73 %, respectively in the ethanol test. The extracts induced a significant increase in mucus mass (p<0.001).

Conclusions

The aqueous and methanol extracts of Nauclea pobeguinii healed ulcers thanks to their anti-inflammatory, anti-oxidant, anti-secretory and cytoprotective properties.

Objectives

TANGO2 deficiency is a rare inborn error of metabolism, with distinct clinical features. The clinical presentations of TANGO2 deficiency are developmental delay, speech difficulties, intellectual disability, non-life-threatening paroxysmal neurologic episodes (TANGO2 spells), acute metabolic crises, cardiac crises, seizures and hypothyroidism. Patients may die in acute metabolic crises. Here we report our experience in the management of an acute metabolic crisis in TANGO2 deficiency.

Case presentation

A 9-year-old patient diagnosed with TANGO2 deficiency was admitted with fever, fatigue, unable to walk. In follow up, encephalopathy, rhabdomyolysis and arrhythmia were detected. Vitamin B-complex was started. Our patient’s mental status and rhabdomyolysis improved dramatically, and cardiac crises ended without Torsades de pointes, ventricular tachycardia and/or fibrillation or myocardial dysfunction.

Conclusions

With this report, we aimed to show the effectiveness of vitamin B-complex in the management of acute metabolic crises.
Postsocialist Statuary Politics in Romania and Bulgaria: An Ambivalent Socialist Heritage
Authors: Preda Caterina
Published: June 2023

Using an approach situated at the intersection of cultural memory studies and (critical) heritage studies, with a focus on the ambivalent socialist heritage of socialist statues and monuments and their changing role in postsocialist public spaces, this article engages with the postcommunist strategies of reckoning with the past in Romania and Bulgaria in the period 1990–2020. Comparing the kinds of monumental memory of communism that were established in these countries, the author discusses how each dealt with their ambivalent socialist heritage through a public memory policy comprising three combined strategies: removal; preservation; and the replacement of communist heroes with anticommunist counter-monuments. The author concludes that stances toward the socialist heritage manifest various tensions in terms of the types of statues that were removed or, alternately, allowed to remain; of the opposition between local and national decisions as well as between the official approach and citizens’ perspectives; and, finally, of aesthetic versus political criteria.
What Do Moldovans Think of and How Do They Talk about the Russian Aggression against Ukraine? Prolegomena for Qualitative Inquiry
Authors: Negură Petru
Published: June 2023

This essay explores the advantages of a qualitative approach based on a preliminary analysis of a collection of street interviews broadcast from March 2022 to March 2023 in the Republic of Moldova via 34 radio programmes. While the results of the opinion polls reflect a clear division of opinion on the war in Ukraine within Moldovan society along pre-existing geopolitical lines, the interviews highlight the possibility of consensus among respondents voicing opposing views on the causes of the war. Regardless of ideological positions however, when asked, most respondents said they wished for peace. The author reflects on the potential inherent in that common response for a type of community based on inclusion and cohabitation.

Objectives

Multiple myeloma (MM) is a common hematological cancer. Hence, it is important to conduct further studies investigating the molecular mechanisms in detail that contributes to myeloma genesis. In addition to genetic changes, epigenetic factors such as miRNAs may influence the expression of myeloma-related genes.

Methods

Our study aimed to detect genes closely related to MM and miRNAs involved in the cancer process by changing the expression of these genes with bioinformatics tools and in vitro methods. Bioinformatics approaches identified hub miRNAs in our study that may have a role in the expression change of genes connected to myeloma. The functional impacts of the chosen miRNA on RPMI8226 and U266 cell lines and the effect of this miRNA on the expression changes of putative target genes were investigated.

Results

The viability of miR-145-5p transfected cells was found to decrease compared to control cells and the expression of IGF1R and NRAS genes were found to be significantly suppressed in both cell lines at mRNA level. Decreased levels of the IGF1R and NRAS genes were confirmed in miR-145-5p transfected cells at the protein level as well as compared to control cells. In addition, IGF1R/miR-145-5p interaction was demonstrated via luciferase reporter assay. However, expression levels of EGFR, KLF4, IRS1, CDK4 and CDK6 candidate genes had no statistically significant difference in miR-145-5p transfected cells compared to control cells.

Conclusions

Mir-145-5p was demonstrated to act as a tumor suppressor miRNA and inhibit the proliferation in MM cell lines via targeting IGF1R and NRAS.
I. L’irripetibilità del processo criminale nell’esperienza giuridica romana
Authors: Laffi Umberto
Published: June 2023

The prohibition of double trial for one and the same fact is a principle that we find theorized and applied in the legal experience of the Romans above all in the field of civil procedural law. Hence modern Romanistic legal science concentrated on this area of law. There are only few specific studies devoted to this subject with reference to criminal procedural law. The problem deserves to be taken up and studied in depth. First of all the author defines the scope of the preclusive effects produced by the judgement as it results from an exhaustive analysis of the epigraphic Lex repetundarum (linn. 1–4, 5, 56). On a more general level, the sources show that the principle of the non-repeatability of criminal prosecutions found substantial application both in the late republican and imperial ages, albeit with the limits and the exceptions that the author highlights. In addition to jurisprudence, the subject of the unrepeatability of the trial lent itself to being dealt with in schools of rhetoric.
II. Il testamentum militis alla luce delle epigrafi funerarie
Authors: Castagnino Francesco
Published: June 2023

This study proposes a different analysis of the Roman military testament by focusing on the information obtained from soldiers’ funerary inscriptions. It aims above all to verify the application of the rules of testamentum militis in practice. On the other hand, it intends to explain some testamentary practices used by the soldiers serving in different territories and to define some problems of military testamentary law, for example, that of the testamenti factio activa of the soldiers without Roman citizenship.
III. The actio utilis in case of pignus nominis
Authors: Smit A.J.H.
Published: June 2023

In Roman law, a creditor could establish a security right by pledging his claim (nomen) against a third person. In case of pignus nominis, the praetor granted the pledgee an actio utilis, which he could use to demand performance from the debtor of the claim that had been pledged to him. The prevailing doctrine with regard to the actio utilis in case of pignus nominis is that this action was formulated after the example of the actio Serviana. Smit explains that in her opinion the praetor did not shape the actio utilis after the actio Serviana, but after the action that the pledgor would have had against his debtor if he himself would have demanded performance from his debtor. Smit discusses the technique the praetor used, compares pignus nominis with assignment and proposes a reconstruction of the formula of the actio utilis that was given in case of pignus nominis.
De principis salute consulere: Zur Praxis der hochverräterischen Erforschung der Lebenserwartung des Kaisers oder des Namens seines Nachfolgers
Authors: Manthe Ulrich
Published: June 2023

De principis salute consulere: The practice of highly treasonable exploration of the emperor’s life expectance or of his successor’s name. The article introduces two procedures of the fortune-telling exploration mentioned in Coll. 15,2,3, until now not described in detail in legal historical papers. The first procedure was an algorithm for determining the reigning emperor’s life expectance described in a 4th century magical papyrus, having a Chinese parallel text of the 3th or 4th century; though the Chinese algorithm was made for another use, there was a remarkably structural similarity to the papyrus algorithm. The second procedure was performed in 371 A. D. for determining the name of the still reigning emperor’s successor, imitating the Delphic oracle ritual; it was sometimes mentioned by Byzantine historians.
VII. Berechtigende Verträge zugunsten Dritter im griechischen Recht?
Authors: Kaiser Wolfgang
Published: June 2023

Contract in favour of a third party in Greek law. The article deals with the question of whether Greek law knew a contract in favour of a third party. For this purpose, inscriptions, literary sources and deeds from Greco-Roman Egypt are examined, which are presented in the literature as evidence for the existence of a contract in favour of a third party. The article comes to the conclusion that there is no reliable evidence for the existence of an entitling contract in favour of third parties in Greek law.

Der praetor, der iudex und die Solidarobligationen
Authors: Schmieder Philipp
Published: June 2023

Praetor, iudex and solidary obligations. In broad terms, in a classical Roman lawsuit the praetor took care of the law, the iudex saw to the evidence and facts. On a closer look, things are not that clear-cut. In some cases, it was up to the iudex to discern the ius civile, and some questions cross the distinction between law and fact. This study concentrates on the realms of the praetor and the iudex by the example of solidary obligations. It turns out that there were inconsistencies both in the delimitation of competences and the results: Some questions were dealt with by the praetor in one action, by the iudex in another, and answered differently.
Bekanntes und Neues zum römischen Vereinsrecht
Authors: Babusiaux Ulrike
Published: June 2023

Old and new insights regarding the Roman law of associations. In a new monograph, B. Zahn, Si quid universitati debetur. Forderungen und Schulden privater Personenvereinigungen im römischen Recht, 2021, argues that associations had no legal personality under Roman law. He thus challenges a well-accepted view of the term corpus as referring to legal personality of associations. The article retraces the arguments of the study with a special attention to the rich epigraphic evidence, and verifies their validity. Whereas most results of the author turn out to be well-founded, the paper attempts to deepen the interpretations of some inscriptions with regard to stipulations, fideicommissa and modus.
Pro Calatoria Themide
Authors: Igimi Mariko
Published: June 2023

Pro Calatoria Themide. Iusta Case and the Living Conditions of Freed Slaves. The Iusta Case has always been understood as a dispute in which Iusta was claiming her freeborn status (ingenua). Under this conception, however, some unsolved mysteries remain. The author tries to reconstruct the case from the perspective that Iusta was claiming to be a beneficiary of the fideicommissio of Stephanus as one of his freed slaves, by drawing a parallel with D. 34,16,1. Based on this understanding, the documents found in Casa del Bicentenario are, in accordance with Themis’ defence strategy, all in support of Stephanus’ widow who refused to pay the maintenance of the young Iusta for the rest of her life.

Published: June 2023

Troso woven cloth, located in Troso village, Jepara city, is one of the various Indonesian cultural heritages first discovered in AD. The purposes of this study are: 1) to investigate the woven cloth and its uses, the relationship between woven cloth with cultural and religious traditions, and the relationship between the woven cloth and local identity; 2) to design a new motif of Troso woven cloth that incorporates the elements of Jepara culture. The study used a practice-based research approach. The data were collected by purposive sampling technique. The results showed that the local community commonly uses woven fabric products as decorative. Troso cloth is also used to design attires, gamis dresses, or koko shirts for the feast day or formal events. The craftsmen of Troso woven fabrics made in Jepara primarily receive orders with motifs from other regions, including Bali, Sumatra, and Kalimantan. In contrast, the original woven fabric motifs distinctive from Troso are rarely known to the general public. The study formulates a new digital-based motif of the Troso fabric pattern that displays the iconic elements of Jepara city. The iconic depictions of Jepara are in the form of turtles, Jepara wooden carvings, and wave patterns. This research is expected to elevate the Troso fabric’s identity as a local identity of Jepara city and contribute to the Troso village community to develop the Troso fabric unique to the region.
Razak Abdul Aziz’s Pepatah Episodes: Re-Imaging the Malay Proverbs through Piano Music
Authors: Zamani Mohd Fairuz
Published: June 2023

Proverb sits under the umbrella of figurative language and is used to sweeten speeches. In Malay, pepatah is the equivalent of this form of figurative language. Razak Abdul Aziz, a Malaysian composer, selected a set of Malay proverbs and adapted them into his piano work, Pepatah Episodes. The composer follows the tradition of piano programme music that uses figurative language elements championed by composers such as Alexander Scriabin, Claude Debussy, and Maurice Ravel. This paper aims to investigate the pepatahs chosen to be paired with the written music, expounding the programme in the movements for piano. Using the programme music analysis framework by Burkholder et al. (2014) and Kregor (2015), the finding shows that the composer chose the pepatahs for one of the three (3) portrayals: (i) imageries in the pepatah (ii) imageries in the meaning, and (iii) imageries in pepatah and meaning. The programme analysis shows that from the nine (9) movements written for piano, four (4) movements portray imageries in the pepatah, three (3) movements portray imageries in the meaning, and two (2) movements portray imageries in the pepatah and meaning. Razak Abdul Aziz challenges the conventions of programme music by having the pepatah set after the music is written, demanding the performer to read it aloud before performing and having the portrayal of the pepatah in the mentioned ways. This provides a different perspective for other composers to produce works using similar frameworks and scholars to analyse musical works.
Music and Mathematics: Processing Repetition Techniques with the Least Common Multiple (LCM) in Rajékan Music Composition
Authors: Budiawan Hery , Ananda Rizky Fauzy
Published: June 2023

This article aims to find a new way to process repetition in musical composition with the least common multiple (LCM) mathematical approach. Music and mathematics have a very close relationship; in music, the element of mathematics with the derivation of physical science is the most relevant and always interesting study of musical composition. This study aims to analyse the music composition of Rizky Fauzy Ananda’s work, Rajékan, by looking at mathematical theory with the approach of The least common multiple (LCM). The method used with practice-led Research as an approach to music composition. The creation research methodology used is Artistic Research through a Practice-Led Research approach which is also integrated with mathematical theory and musicology, especially music composition. The results of this creative Research prove that repetition in music and in the context of life is important and mathematics always present in human life. Repetition has largely underpinned development in music. In the context of life, reps are things that always exist in everyday life, such as worship activities and lifestyles. Such repetitive phenomena can also provide certain learning or meaning for the individual. In the context of education, reps are the easiest and most basic way of learning to learn and recall about understanding something. Repetition processing whose ideas come from the phenomenon of researchers’ self-experience, produces two repetition processing techniques with the LCM mathematical style (1) magnification and reduction of sound values that make up the cycle, (2) imitation.

Published: June 2023

Using the method of low-temperature nitrogen adsorption/desorption, the porous structure of nanoporous carbon materials obtained by alkaline activation of light industry waste (walnut shells) with subsequent thermal modification was investigated. The optimal relationship between temperature and modification time has been established. It is shown that an increase in the modification temperature reduces the transition time of micropores into mesopores and leads to a decrease in the specific surface area and total pore volume. Thus, the material obtained at a modification temperature of 400 ºC and a holding time of 120 min is characterized by the maximum specific surface area of 940 m2/g. It has been investigated that an increase in the time of temperature modification leads to an increase in specific electrical conductivity.

It has been established that the doping of activated carbon material with chromium and manganese increases the specific capacitance of storage devices based on the charge-discharge mechanism of a double electric layer (DEL) by ~70 % and leads to a decrease in their internal resistance by 30-35 %. The main reason for this rise is the transformation of the electron energy spectrum due to an increase in the density of electronic states, as a result of which a much larger number of electrolyte ions (primarily positive ones) participate in the formation of DEL and cause an increase in the specific capacitance of these devices. It has been shown that laser irradiation stimulates the metal penetration into the bulk of carbon material.

El desciframiento del acadio fue aceptado oficialmente por la Royal Asiatic Society el 29 de mayo de 1857.El proceso fue un largo viaje en el que tomaron parte muchos estudiosos, culminando en los trabajos de Edward Hincks y Henry C. Rawlinson. Pero las bases de la escritura cuneiforme y el método aplicado para descifrarla toparon con el escepticismo académico. Para disiparlo, la Royal Asiatic Society realizó una prueba en la que participaron cuatro asiriólogos: Hincks, Rawlinson, Oppert y Talbot. Los cuatro eruditos debían traducir independientemente y sin contacto entre ellos una inscripción hallada recientemente en Qalat Shergat: el prisma de Tiglat-Pileser I. La comparación de las cuatro traducciones demostró que el método de Hincks y Rawlinson era correcto, y el desciframiento fue finalmente reconocido.Palabras clave: Desciframiento, escritura cuneiforme, acadio, Hincks, Rawlinson, Talbot, Oppert, prisma de Tiglat-Pileser I. AbstractThe decipherment of Akkadian was officially accepted by the Royal Asiatic Society on May 29, 1857.

"Azul para los dioses". De Oriente a Occidente: La búsqueda del lapislázuli durante el III milenio a. C.
Authors: Del Cerro Carmen
Published: June 2023

La falta de materias primas en Mesopotamia obligó a sus habitantes a buscarlas en varias direcciones. Podemos rastrear esos materiales a través del registro arqueológico y de la información textual. Así, tratamos de localizarlos topónimos antiguos y sus fuentes de materias, ya que un gran número de estos lugares están recogidos en los textos mesopotámicos y egipcios: Aratta, Tukriš, Mar?asi, Dilmun, Melu??a, Magan, Tefreret, etc. Desde el Este, estas regiones ofrecieron una gran variedad de piedras, metales, maderas o animales exóticos, que llegaron no solo a Mesopotamia sino también a Siria y a Egipto. Uno de esos materiales nos parece extraordinario; el lapislázuli, una piedra azul que aparece en templos, palacios, contextos funerarios, registros económicos y textos literarios, relacionada con reyes, gobernantes, mercaderes y dioses.Palabras clave: Comercio, III milenio a.C., Lapislázuli, materias primas, Mesopotamia, Siria, Egipto, Inanna AbstractThe lack of raw materials in Mesopotamia pressed to its habitants to look for them in several directions. We can track these materials through the Archaeological Record as well as the textual information. Thus, we try to locate ancient names of Lands and its sources, since a lot of them are included in Mesopotamian and Egyptian texts: Aratta, Tukriš, Mar?asi, Dilmun, Melu??a, Magan, Tefreret, etc. From Far East, these regions offered a huge variety of stones, metals, woods or exotic animals, which reached not only Mesopotamia but also Syria and Egypt. One of this materials seems to us remarkable; the blue Lapis lazuli, a stone that is displayed in temples, palaces, funerary contexts, economical records and literary text, related to kings, rulers, merchants and gods.Keywords: Trade, III Millennium BC., Lapis lazuli, Raw Materials, Mesopotamia, Syria, Egypt, Inanna
La città de 'Arugu e la geografia del culto del regno di Ebla (Siria, XXIV sec. A. C.)
Authors: Biga Maria Giovanna
Published: June 2023

La geografia del culto del regno di Ebla comprende centri di diversa grandezza e importanza. Oltre ai grandi centri di culto quali Aleppo, Arugadu, Luban, Zuramu, Uguaš, MaNE, dedicati ad alcune delle maggiori divinità del pantheon, e venerati probabilmente da tutte le genti di Siria, vi erano sul territorio del regno molti luoghi santi minori, di cui alcuni legati al culto degli antenati regali defunti della dinastía eblaita. In questo articolo si propone di annoverare, tra i luoghi santi del regno di Ebla, il centro di ’Arugu dal quale proviene l’uomo che recita la benedizione in entrambi i rituali di riconferma della regalità; sono inoltre persone da ’Arugu a consegnare tessuti per la cerimonia di purificazione del re Išar-damu e della regina Tabur-damu dopo la morte della regina madre Dusigu e di due principesse della corte.Parole chiave: Geografia, centri di culto, rituali, Binaš, ’Arugu. AbstractCultic geography of the Ebla kingdom includes sanctuaries and cultic centers of different importance. Some major sanctuaries, such as Aleppo, Arugadu, Luban, Zuramu, Uguaš, MaNE, dedicated to some deities of the Eblaite and Syrian pantheon, are often quoted in the texts. Other minor cultic centers are attested too and some of them are places where a cult of ancestors is documented. The author proposes to insert among these cultic centers the city of ’Arugu from which comes the man who has a role in both the rituals of renewal of royalty; people from ’Arugu offer gifts of purification to king Išar-damu and to queen Tabur-damu on occasion of the death of queen mother Dusigu and of the death of two princesses, Darib-damu and Tište-damu.Keywords: Geography, cultic centers, rituals, Binaš, ’Arugu.
Influencia del Profesorado en las Actitudes hacia la Inmigración de los Alumnos. Evidencias desde PISA 2018
Authors: Rodríguez-Esteban Agustín , González-Mayorga Héctor
Published: June 2023

La atención a la diversidad en una sociedad cada vez más multicultural es uno de los grandes retos a los que se enfrenta el sistema educativo español. El presente estudio se ha centrado en analizar en qué medida la conducta del profesorado predice las actitudes de los alumnos hacia la inmigración. Para este propósito, se han utilizado los datos españoles de PISA 2018, con una muestra total de 29.324 estudiantes. Para el análisis de los datos, se han empleado un modelo de análisis lineal multinivel y tres modelos factoriales de análisis de la varianza. Los resultados han demostrado que, según la percepción de los estudiantes, el profesorado que realiza comentarios negativos hacia los inmigrantes muestra bajas expectativas hacia el alumnado extranjero y culpabiliza de los problemas sociales a este colectivo ejerce una influencia negativa en la adopción de determinadas actitudes por parte del alumnado, especialmente en el sexo masculino. Estos resultados ponen de manifiesto la necesidad de formación, tanto inicial como permanente, del profesorado para la atención del alumnado inmigrante en el aula en sus dimensiones didáctica y metodológica. Se concluye que el contexto educativo es el foro adecuado para el fomento de actitudes de respeto y tolerancia hacia la inmigración y la diversidad cultural.

Published: June 2023

Tras la pandemia, la visibilidad de la escuela rural se ha hecho más patente por  considerarla un elemento vertebrador del territorio y garante del asentamiento de población. Algunos medios de comunicación dan cobertura a sus demandas, subrayando las ventajas de este modelo educativo y denunciando problemáticas como la despoblación, que las aboca a la extinción. Este estudio identifica los hitos relevantes, el enfoque y las temáticas priorizadas en torno a las que giran 100 artículos publicados durante 2020-2021 en la prensa digital de las Comunidades Autónomas (CCAA) españolas con mayor población escolarizada en zonas rurales (15-25%). La metodología es mixta, centrada en el análisis de contenido y posterior tratamiento estadístico de los datos. Los resultados demuestran el interés que despierta la escuela rural en los diarios de las CCAA estudiadas, especialmente en el ámbito local. Priman testimonios de miembros de la comunidad educativa y local, visibilizando mayoritariamente hechos que la empoderan -metodologías y proyectos innovadores, ratios envidiables e implicación familiar-, aludiendo a las ventajas de su enclave natural privilegiado. También denuncian cierres de escuelas y limitaciones: brecha digital, poca conectividad, falta de profesorado o transporte, erigiéndose en altavoz de estas demandas, y exigiendo medidas a los responsables políticos para solventarlas.
Factores Asociados al Rendimiento en Matemáticas de Estudiantes Españoles en Educación Primaria
Authors: Ortega Pablo Javier
Published: June 2023

El presente estudio analiza el efecto de los factores del estudiante sobre el rendimiento en matemáticas en función del género a partir de la base de datos de TIMSS 2019 en España, en el que participaron 9512 estudiantes de 4º curso de Educación Primaria. Se ha realizado un Análisis Factorial Exploratorio (KMO= .941 y nivel de significación de Bartlett =.000) sobre los 18 ítems del cuestionario del alumnado, ordenados en una escala de Likert de 4 niveles (1=Muy en desacuerdo y 4=Muy de acuerdo), pruebas t de Student y Análisis de Covarianzas (ANCOVA). Se han identificado tres factores: la actitud, la ansiedad y la autoeficacia en matemáticas. Los resultados muestran que las niñas experimentan más ansiedad ante las matemáticas que los niños, aunque tiene más efecto sobre el rendimiento de ellos. En la autoeficacia, el segundo factor más influyente, se encontraron mayores diferencias entre niños y niñas, con más efecto sobre el rendimiento de ellos. La actitud es el factor que tiene menos efecto sobre el rendimiento. Esto constituye una aportación relevante para reducir la brecha de género en educación secundaria.

Authors: Kloc Agnieszka
Published: June 2023

Streszczenie: W ostatnich latach społeczeństwo globalne stanęło w obliczu wyzwania, jakim jest walka z „niewidzialnym wrogiem”. W okresie pandemii personel medyczny wykonywał swoją pracę w wyjątkowych i nieznanych warunkach. Jednocześnie obciążenie psychiczne, stres, lęk przed zakażeniem, różnorodność zdarzeń, poczucie bezradności – to tylko kilka elementów, z jakimi m.in. pielęgniarki musiały mierzyć się podczas wykonywania czynności bezpośrednio przy pacjencie zainfekowanym wirusem SARS-CoV-2. Celem niniejszej pracy było określenie, w jaki sposób pandemia COVID-19 wpływa na występowanie stresu u pielęgniarek pracujących w oddziałach zakaźnych.
An investigation of the variation of pore structure in Eucalyptus fibre during recycling
Authors: Guo Wen-Jie , Wang Yan , Huang Ming-Zhi , Wan Jin-Quan , Ma Yong-Wen
Published: June 2023

Variation in the pore structure of eucalyptus fibre during recycling was investigated using low-temperature nitrogen adsorption, atomic force microscopy (AFM), and fractal geometry. The Brunauer- Emmett-Teller (BET) surface area of the fibre fell to 55.1% of the original value after the first cycle, and to 49.0% after the second cycle, ultimately declining to 35.0% after the fourth. The Barret-Joyner- Halenda (BJH) adsorption cumulative pore volume fell to 38.4% of the original by the fourth. After four cycles, the average pore diameter fell to 82% of the original. AFM tests showed that the pore structure in fibre expressed high self-similarity in statistics, and the pore structure in the fibre could be regarded as a fractal. Fractal geometry analysis of the results showed that the fractal dimension of eucalyptus virgin fibre is 2.954. With the number of process cycles increasing, the fractal dimension fell to a minimum of 2.886 after four cycles. The water retention value (WRV) of the fibre was proportional to the fractal dimension and the crystallinity of fibre.
Reduction of the recalcitrant COD of high yield pulp mills effluents by AOP. Part 1. Combination of ozone and activated sludge
Authors: Meza Pedro R. , Felissia Fernando E. , Area Maria Cristina
Published: June 2023

The aim of this work was to study the effect of ozone, either alone or combined with an activated sludge system, on the reduction of the recalcitrant COD in the effluent of a chemimechanical pulping (NaOH -Na2SO3) integrated mill. Several alternative schemes involving ozonation were tested on liquors and effluents of the pulp mill, and on two kinds of effluents were taken at different points of an activated sludge pilot plant. The largest decrease in COD was 33%, whereas that in aromatic compounds (absorbance at 232.5 nm) was of 73%. The most obvious result of the ozone treatment was effluent decolorization. It was not possible to use ozonation as tertiary treatment, as ozone was necessary to treat the BOD generated, and therefore the effluent must necessarily pass through a biological treatment. With a scheme including an intermediate ozonation between two secondary treatments (post-activated sludge and pre-aeration lagoon), the maximum reductions achieved were of 70% in COD, of 93% in aromatics, and of 96% in color. The limits of COD allowed by the environmental regulations (<250 mg/L) could be achieved with the following stages: 1) primary clarifier, 2) activated sludge system, 3) ozonation, 4) aeration lagoon, and 5) stabilization lagoon.
