Non-infectious unilateral cervical lymphadenopathy in children - a case report
Authors: Bukovec Petra , Kranjčec Izabela , Gašparov Slavko , Živić Helena
Published: March 2023

Cervical lymphadenopathy in children is often the reason to seek medical attention. According to the literature, 90% of children aged 4-9 years has cervical lymphadenopathy, mainly caused by acute infections, that is treated in the out-of-hospital setting. In a small, but significant number of cases, cervical lymphadenopathy is caused by malignancy and wide range of other clinical entities, that require more detailed clinical approach. Three patients with non-infectous unilateral cervical lymphadenopathy are presented; adolescent boy with unicentric Castleman disease, young adult with progressive transformation of germinal centers, and an infant with viral parotitis mistaken for cervical lymphadenopathy. Unicentric Castleman disease was diagnosed by pathohistological assesment of excised lymph node to a 14-year-old boy after 7 months of persistent cervical lymphadenopathy, and close follow-up was suggested as no disease progression was verified by PETCT. Histopathological-clinical diagnosis of progressive transformation of germinal centers was established in an adolescent with 3-month history of lymphadenopathy, after extensive radiological and infectious assesment. Chronic reccurent course of the disease was once again confirmed, as this patient awaits his third extirpation in the last year. Viral parotitis is one of the conditions that can mimic cervical lymphadenopathy as showed with the third presented patient – a 6-month-old male infant with the submandibular swelling lasting for three days. This article emphasises the importance of a detailed history taking and clinical assesment, but is also a reminder of a less often, noninfectious causes of lymphadenopathy in children, where systematic approach is the key to a correct diagnosis and treatment.
Exile Songwriters of the Palestinian Revolution (and the Problem with Sugar Man)
Authors: Brehony Louis
Published: March 2023

Bringing together musical research on three distinct locations of Palestinian displacement, this article explores the contributions of resistance songwriters Zeinab Shaath, George Totari, and George Kirmiz. Drawing on ethnographic fieldwork, including film-making, the works of the artists are explored through presentations of their lives in music, their social relationships, and journeys traversed by themselves and their music. Their approaches to songwriting and presentations of Palestinian narratives of resistance are discussed in relation to their stated political and social goals, which developed in parallel to an ongoing Palestinian Revolution in the region. The article proceeds from problems associated with the Sugar Man film phenomenon, in “lost” and “discovered” cultures, arguing that the singing and activism of the musicians finds greater relevance in the pursuit of ahdaf (“targets”) by Palestinian revolutionaries. Concepts such as musical genre and social organization are explored through their ability to present arguments on the way forward for exiles and those standing in solidarity with their cause.

In Ethiopia Long-acting contraception method utilization was found low (22.7%) among female healthcare providers. However, there is no study has been conducted on the utilization long-acting contraception methods among female healthcare providers in the study area. These studies addressed important variables such as socio-demography and individual factors that might affect the use of long-acting contraceptive methods among female healthcare providers. We assessed the utilization of long-acting contraceptive methods and associated factors among healthcare providers in South Wollo Zone public hospitals, Amhara Region, Ethiopia, in 2021.An institutional-based cross-sectional study was conducted among 354 female healthcare workers in the South Wollo Zone hospitals from March to April, 2021. The participants were selected using a systematic random sampling technique. The data were collected using self-administered questionnaires entered into Epi-data version 4.1 and exported to SPSS version 25 for analysis. Bi-variable and multi-variable logistic regression analyses were performed. The adjusted odds ratio (AOR), along with a 95% confidence interval (CI), was estimated to measure the association. The significance level was set at a P- value under 0.05. The current utilization of long-acting contraceptive methods among female healthcare providers was found to be 33.6% [95%, CI 29–39)]. Discussion with a partner [AOR = 2.277,95% CI, (1.026–5.055)], method shift/switched [AOR = 4.302,95% CI, (2.285–8.102)], knowledge of the respondent [AOR = 1.887,95% CI, (1.020–3.491)], and ever birth [AOR = 15.670,95% CI, (5.065–48.49)] were significant factors toward the utilization of long-acting contraceptive methods. The current utilization of long-acting contraceptive methods was found to be low. Therefore, encouraging partner discussions through a targeted information education communication intervention strategy should be intensified to improve long-acting contraceptive methods utilization.
Influence of high-energy laser therapy to the patellar tendon on its ligamentous microcirculation: An experimental intervention study
Authors: Brandl Andreas , Egner Christoph , Reisser Ursel , Lingenfelder Christian , Schleip Robert
Published: March 2023

Laser therapeutic applications, such as the use of high energy lasers (HILT), are widely used in physical therapy, but basic studies on the mechanisms of action of HILT on tendinous/ligamentous tissue are largely lacking. The aim of this study was to investigate microcirculatory changes of the patellar tendon by HILT. 21 healthy volunteers were included in the present investigation. Before and after HILT, as well as 10 minutes later, the microcirculation was measured by noninvasive laser Doppler and white light spectroscopy (O2C device). Tissue temperature was recorded at the measurement time points using thermography. Blood flow increased significantly by 86.38 arbitrary units (AU; p < 0.001) after the intervention and by 25.76 AU (p < 0.001) at follow-up. Oxygen saturation increased by 20.14% (p < 0.001) and 13.48%, respectively (p < 0.001), whereas relative hemoglobin decreased by 6.67 AU and 7.90 AU, respectively. Tendon temperature increased by 9.45° and 1.94° Celsius, respectively. Acceleration of blood flow by improving the flow properties of erythrocytes and platelets may have caused the results. HILT could be a therapeutic perspective for tendon pathologies with impaired microcirculation, although further studies are needed to validate the experimental results.

Authors: Anderson Robert , Kim Sungwook , Roberts Nia , Petrou Stavros
Published: March 2023

Objectives

This study carried out a systematic literature review of economic evaluations of varicella vaccination programmes from the earliest publication to the present day, including programmes in the workplace and in special risk groups as well as universal childhood vaccination and catch up programmes.

Methods

Articles published from 1985 until 2022 were sourced from PubMed/Medline, Embase, Web of Science, NHSEED and Econlit. Eligible economic evaluations, which included posters and conference abstracts, were identified by two reviewers who scrutinised each other’s selections at both title and abstract and full report stages. The studies are described in terms of their methodological characteristics. Their results are aggregated by type of vaccination programme and the nature of the economic outcome.

Results

A total of 2575 articles were identified of which 79 qualified as economic evaluations. A total of 55 studies focused on universal childhood vaccination, 10 on the workplace and 14 on high risk groups. Twenty-seven studies reported estimates of incremental cost per quality-adjusted life year (QALY) gained, 16 reported benefit-cost ratios, 20 reported cost-effectiveness outcomes in terms of incremental cost per event or life saved and 16 reported cost-cost offset results. Most studies of universal childhood vaccination reported an increase in overall costs to health services, but often a reduction in cost from a societal perspective.

Conclusions

The evidence surrounding the cost-effectiveness of varicella vaccination programmes remains sparse with contrasting conclusions in some areas. Future research should particularly aim to encompass the impact of universal childhood vaccination programmes on herpes zoster among adults.

Authors: Aliyatul Fikroh Retno
Published: March 2023

Cervical cancer is the second leading cause of death in women. Many cancer treatments currently provide toxic effects on normal cells. Therefore, alternative treatment using chalcone derivatives has potent anticancer properties that can help reduce cancer side effects. Chalcone derivatives with halogen and methoxy groups in ring B can potentially inhibit cancer cells. This research aimed to synthesize halogen-substituted chalcone by a green chemistry approach and determine activity against cervical cancer (HeLa) cell lines. The Claisen-Schmidt reaction was used to synthesize 2'-hydroxy-2-bromo-4,5-dimethoxychalcone using a grinding technique. The purity of the synthesized compound was determined using thin-layer chromatography and melting range. The compounds' structures were characterized using FTIR, MS 1H, and 13C-NMR. The result showed that the synthesized compound was yielded in 53% as a yellow solid. In vitro cytotoxicity of the synthesized chalcone was evaluated by the MTT assay method. The IC50 of the compound was 67,23 μg/mL as a moderate activity inhibiting cervical cancer (HeLa) cell lines. Based on the IC50 value, this compound can be a candidate for anticancer against Cervical cancer (HeLa) cell lines

Swearing and Learning: The Importance of Swear Words in Ulf Stark’s Rymlingarna and Oskar Kroon’s Överallt och ingenstans

This study investigates the uses and functions of swear words in children’s literature, analyzing Ulf Stark’s Rymlingarna (The Runaways, 2018) and Oskar Kroon’s Överallt och ingenstans (Everywhere and Nowhere, 2020). In both novels there are characters swearing recurringly, even though swear words are usually not frequently used in literature for young children. A starting point for the article is that the swear words seem to be important in the stories, that the function is not only to underline emotions, or create realism, but also to contribute to the themes of the books. First, the functions of swearing in language and literature are presented, and similarities with functions of humor are pointed out. The study shows that the use of swear words affects both what is being told, and how; they contribute simultaneously to the aesthetics and pedagogy of the novels. Through swear words, characters and close relationships are portrayed. Norms are challenged, and swearing is sometimes part of gaining agency and creating a room of one’s own for the characters. This also means that swearing affects subjectivity and how different characters come to understand themselves and others in the world. Finally, the swear words can be seen as connected to the theme, which in both novels discusses how we can continue to live, through grief and loss of loved ones.

Electrophysiological activity from over the cerebellum and cerebrum during eye blink conditioning in human subjects
Authors: Todd Neil P. M. , Govender Sendhil , Keller Peter E. , Colebatch James G.
Published: March 2023

We report the results of an experiment in which electrophysiological activity was recorded from the human cerebellum and cerebrum in a sample of 14 healthy subjects before, during and after a classical eye blink conditioning procedure with an auditory tone as conditional stimulus and a maxillary nerve unconditional stimulus. The primary aim was to show changes in the cerebellum and cerebrum correlated with behavioral ocular responses. Electrodes recorded EMG and EOG at peri‐ocular sites, EEG from over the frontal eye‐fields and the electrocerebellogram (ECeG) from over the posterior fossa. Of the 14 subjects half strongly conditioned while the other half were resistant. We confirmed that conditionability was linked under our conditions to the personality dimension of extraversion‐introversion. Inhibition of cerebellar activity was shown prior to the conditioned response, as predicted by Albus (1971). However, pausing in high frequency ECeG and the appearance of a contingent negative variation (CNV) in both central leads occurred in all subjects. These led us to conclude that while conditioned cerebellar pausing may be necessary, it is not sufficient alone to produce overt behavioral conditioning, implying the existence of another central mechanism. The outcomes of this experiment indicate the potential value of the noninvasive electrophysiology of the cerebellum.

Authors: Elbarbary Ahmed M. , Sharaf El-Deen S. E. A. , Abu Elgoud E. M. , Sharaf El-Deen G. E.
Published: March 2023

In this work, a hybrid composite of activated carbon (AC) functionalized with terpolymer hydrogel of polyvinyl alcohol/polyacrylamide/polyacrylic acid (PVA/PAAm/PAA) was prepared by γ-irradiation and used efficiently for sorption of Eu(III) and Sm(III) ions from aquatic solutions. Sewage sludge from the wastewater treatment plant was used to prepare AC, then activated by zinc chloride (ZnCl2) and thermal treatment at 550 °C. The modification of AC by functionalized terpolymer has successfully occurred mainly to limit its precipitation and to increase its adsorption capacity which allowed capable interaction with the metal ions. Different advanced techniques were used to investigate the structure and properties of (PVA/PAAm/PAA)/AC composite before and after the sorption process. Using 20 kGy is sufficient to get gel fraction of 87.5% and equilibrium swelling was 39.1 g/g. The (PVA/PAm/PAA)/AC composite hydrogel showed a pHpzc at pH ∼3. FTIR and EDS confirmed the successful integration of the functional groups and constituent elements of AC into terpolymer hydrogel components. XRD results confirmed the typical diffraction peaks of AC in the composite and the calculated average crystallite size was 167.4 nm. The SEM morphology of AC appeared as grains distributed well into the composite. The effect of synthesized AC, PVA/PAAm/PAA and (PVA/PAAm/PAA)/AC sorbents were tested to uptake of Eu(III) and Sm(III) ions. The highest uptake was noticed for (PVA/PAAm/PAA)/AC composite and it was selected for studying the parameters affecting the sorption process such as pH, shaking time, initial concentration, and adsorbent dosage. Results of the experimental data showed that Langmuir isotherm and Pseudo-second-order kinetic models fit well the sorption process of both Eu(III) and Sm(III) ions with maximum sorption capacities of 173.24 and 160.41 mg/g and uptake percentage of 82.3% and 83.4%, respectively at the optimum conditions of pH 4, 180 min, 100 mg/L metal concentration and 0.01 g adsorbent mass. The thermodynamic parameters indicated endothermic and spontaneous nature of the sorption process. Additionally, the as-prepared composite afford high selectivity and uptake capacity for Eu(III) and Sm(III) ions at pH 4 even in the presence of competing cations; Cd(II), Co(II), Sr(II) and Cs(I). The (PVA/PAAm/PAA)/AC composite was used efficiently as a unique and selective adsorbent for the sorption of Eu(III) and Sm(III) ions.

Authors: Etcheverry Clara
Published: March 2023

E-commerce continues its expansion, and most retail groups have opened online distribution channels in the French grocery market. Using purchasing data, I develop a store choice model and a supply model to estimate the effect of the online distribution channel on consumer welfare and retail competition. E-commerce leads to a small decrease in consumer surplus. Furthermore, only online leaders obtain more market shares and profits while the majority of retailers globally get lower market shares and profits with e-commerce.
Transcendental Homelessness, Planetary Homes (In a Time of War): Perspectives From North and South
Authors: West-Pavlov Russell
Published: March 2023

This speculative meditation on homelessness takes as its starting point media photos of apartments in the Ukraine whose walls have been shot away by Russian artillery barrages or bombing raids. It suggests that these images of homelessness prompt us to address larger issues of being at home in the world. Beginning with twentieth-century meditations from Germanophone philosophy, proceeding via several Antipodean examples, and culminating with perspectives from the Global South, the essay urges us to turn our gaze towards modes of open-ended homeliness in the world that are vital for our ongoing habitation of the ‘environmental niche’ that is planet Earth.
The The Effects of Input Processing Instruction on The Acquisition of Expression of Giving and Receiving (Juju Hyougen) by the Indonesian Learners of Japanese
Authors: Visiaty Arianty , Fitriani Nisrina Nur
Published: March 2023

This study examines the effectiveness of learning the Japanese expression of giving and receiving by applying input processing instruction to Japanese learners of Indonesia at the intermediate level. This study was quantitative research using data obtained from four tests, namely pre-test (first test), post-test (second test), test after two weeks (third test), and test after five weeks (fourth test). The study's respondents are university students of Al Azhar in their third year at the Japanese language and culture department. Based on the results of the first and the second test, it can be said that learning the expression of giving and receiving the Japanese language that applies input processing instruction is effective. However, the comparison results of the first and second tests, second and third tests, and second and fourth tests show that the input exercise does not affect the respondents' ability after two weeks and five weeks after receiving treatment. The average score of respondents tends to decrease in the test after two and five weeks, so it can be said that the input processing instruction does not affect the acquisition of Japanese expressions of receiving and giving. This can be caused by the lack of opportunities to use Japanese expressions of receiving and giving and the lack of exposure to an input of these expressions in subsequent class activities and students' daily lives.

Poster Presentation: A Project-Based Integrated Language Learning to Enhance Soft Skills of Japanese Language Learners
Authors: Wahidati Lufi , Kharismawati Mery
Published: March 2023

This study investigates how Japanese language students view group poster presentations as a project-based integrated language learning process. Japanese language students in higher education must possess both the hard and soft skills necessary for the workplace in the twenty-first century. Therefore, developing Japanese language learning methods is necessary to enhance both learners' soft skills and Japanese proficiency. The project-based learning (PjBL) approach was carried out through a project assigned in the Speaking course, namely in group poster presentations. This research investigated students' perceptions after implementing poster presentation activities to develop their soft skills. The research data were collected using questionnaires, interviews with selected students, and observations during the 8-week project. The results of this study show that the Japanese language students respond favourably to the implementation of the group poster presentation project. Poster presentation activities encourage the students to practice their four Japanese language skills (listening, speaking, reading, and writing) in realistic communication. At the same time, these group project activities help the students understand the value of interpersonal skills, project management, critical thinking and problem-solving, teamwork, and communication skills in completing a project.

Retratos y figuras en la edición ilustrada de los "Episodios Nacionales" (1881-1885). Una aproximación
Authors: Alonso Cecilio
Published: March 2023

En este artículo se estudia la función de la imagen gráfica en la edición ilustrada de las dos primeras series de Episodios Nacionales (1882-1885). Se intenta resaltar la relación aleatoria de continuidad fisonómica y de atrezo entre la cronografía imaginaria propuesta por Galdós para construir a sus personajes a lo largo del tiempo y la interpretación evolutiva de los cambios que sugieren los diversos dibujantes que tratan de expresarlos. Se trata de conjeturar si ante el privilegiado lector‑usuario de la lujosa edición ilustrada, la presencia de las figuras gráficas sustituía, completaba o distorsionaba la percepción cognitiva del personaje. Y si, en cierto modo, Galdós como editor e impulsor de esta versión gráfica de su propia obra, anticipaba disciplinas narrativas interartísticas ―cine, cómic, fotonovela…― que habían de desarrollarse plenamente en el siglo xx.

Patrón esquelético de roedores Cávidos en la secuencia arqueológica de Cueva Tixi, Tandilia Oriental (Pleistoceno Tardío-Holoceno Tardío), Argentina
Authors: Quintana Carlos A.
Published: March 2023

Se analizan los roedores cávidos Cavia aperea y Galea tixiensis del sitio arqueológico Cueva Tixi. Se comparan atributos relacionados con el patrón de preservación esqueletaria de las muestras de estos cávidos incorporados a la subsistencia indígena (niveles superiores) respecto de las muestras producidas por la actividad de depredadores (niveles inferiores). Esos mismos atributos se evalúan considerando también dos grupos de control: micromamíferos acumulados por aves rapaces en toda la secuencia de Cueva Tixi y cávidos explotados antrópicamente del sitio Cueva El Abra. Se concluye que en Cueva Tixi existen diferencias en el patrón esqueletario entre la muestra de cávidos incorporados por sociedades indígenas y las de los cávidos y otros micromamíferos incorporados por aves rapaces. Sin embargo, se advierte que esas diferencias no son categóricas sin la información complementaria procedente de evidencias del procesamiento carnicero y de la caza (e.g. huellas de corte, selección de individuos adultos).

Published: March 2023

Teachers for Future es un movimiento social, que se gestiona y comunica a través de las redes, formado por un colectivo de docentes preocupados por el cambio climático y el medio ambiente que lleva a cabo diversas iniciativas y campañas que están teniendo impacto en aulas y centros educativos. Este artículo presenta una investigación llevada a cabo mediante un diseño no experimental a través del método descriptivo desarrollada con docentes que forman parte de este movimiento para tratar de conocer el perfil de profesorado que participa en TFF, sus motivaciones, la forma de comunicarse, las iniciativas en las que participa y el tipo de acciones que realiza. Los resultados muestran que el perfil docente es diverso, pero en su mayoría presentan preocupación por temas medioambientales. También se ha encontrado que la implicación de los equipos directivos está relacionada con la participación de las familias en las iniciativas y con el impacto de las mismas en el aula. Se concluye que el movimiento es bastante transversal desde el punto de vista disciplinar y que los docentes que participan consideran que tiene una repercusión positiva y contribuye a la mejora educativa. Además, el papel de las redes virtuales es fundamental en el movimiento, ya que permite que los docentes lo conozcan, se impliquen en las campañas y se comuniquen entre ellos.

Published: March 2023

It is difficult for papermaking wastewater to reach the discharge standard with only a sequencing batch reactor activated sludge process (SBR). This study developed an advanced wastewater treatment system with nano-TiO2 colloid photoelectrocatalysis and heterogeneous photocatalysis (PEPC). First, the performances of different flocculation processes and their influences on the subsequent PEPC process were studied. The recycling of the nano-TiO2 colloid photocatalyst was further investigated. The results showed that the ternary composite flocculation process using both the inorganic flocculant and the nano-TiO2 colloid (1 × 10-3 wt%) had the best flocculation effect with a suspended solid (SS) removal rate of 93.5% and a chemical oxygen demand (COD) removal rate of 66.9%. It also achieved the best PEPC treatment performance with a COD removal rate of 93.6% in 90 min with the 0.05 wt% dosage of the nano-TiO2 colloid photocatalyst. Moreover, the COD removal rate reached 88.5% after four recyclings of the nano-TiO2 colloid photocatalyst, which demonstrated the excellent reusability of the nano-TiO2 colloid photocatalyst. Finally, based on the PEPC process, an automatic and continuous pilot-scale system was established. Its successful operation suggests the feasibility of operating PEPC technology at an industrial scale.
Effects of asphodel tuber and dolomite on the properties of bio-hybrid films processed by a twin screw extruder
Authors: Karaoğul Eyyüp
Published: March 2023

Bio-hybrid granules made from asphodel tuber (AT), starch, polyvinyl alcohol (PVOH), and dolomite were formed using a twin-screw extruder. The granules were prepared using starch or AT as a raw material, glycerol as a plasticizer, TiO2 as a heat stabilizer, and dolomite as a filler. The films were fabricated from granules by hot-press moulding. The mechanical (e.g., tensile strength, elongation-at-break, and modulus of elasticity), physical (e.g., weathered, density, hardness, color, water absorption and solubility in different temperatures, water vapor permeability, and oxygen permeability), and chemical properties (e.g., carbonyl index and vinyl index) of the films were analysed. The properties of the films were noticeably enhanced with AT and dolomite. Asphodel tuber improved the water solubility, water absorption, and weight loss after weathered. Asphodel tuber could resist water diffusion into the films because of its hydrophobic property, like dolomite. Dolomite also exhibited strong mechanical properties and barrier properties to water and oxygen. Additionally, cross-linking most likely occurred with inter- or intramolecular interactions. The interactions among the AT, starch, dolomite, and plasticiser with PVOH were interpreted as esterification, etherification, hydrogen bonding, carbonyl bonding, and vinyl bonding in the molecular structure of the bio-hybrid films.
Effect of process parameters in pilot scale operation on properties of organosolv lignin
Authors: Rossberg Christine , Janzon Ron , Saake Bodo , Leschinsky Moritz
Published: March 2023

One of the major challenges in transforming from fossil to bio-based materials is the production of biomass-derived intermediates in a well-described, reproducible manner at a relevant scale. Lignin, as the only renewable aromatic resource, will play an important role in the future bioeconomy. Various grades of lignin were produced at Fraunhofer CBP’s pilot plant by variations of the following parameters: raw material (beech wood, spruce wood, and wheat straw), H-factor (combining the effect of temperature and time), addition of sulfuric acid ω(H2SO4), and the precipitation procedure. During the optimization of the process conditions for lignin production an in-depth analytical characterization was done by acid hydrolysis with subsequent anion-exchange chromatography (AEC), elementary analysis, 31P-nuclear magnetic resonance spectroscopy (NMR), size-exclusion chromatography (SEC), and differential scanning calorimetry (DSC) to monitor changes in structure and selected properties.
Response surface optimization of ammonium sulfite pretreatment for fermentable sugar production from wheat straw

Published: March 2023

The development of a clean and sustainable pretreatment is of great importance for the production of fermentable sugars. In this study, an ammonium sulfite (AS) pretreatment of wheat straw was optimized based on response surface methodology with a three-level, three-factor Box-Behnken design. The investigated factors were AS dosage, pretreatment time, and pretreatment temperature. The effectiveness of the AS pretreatment was evaluated using the standard enzymatic hydrolysis procedure. A second-order polynomial fit was performed to fit the experimental data, and the model analysis showed that the effect of the AS dosage on the final total sugar yields was much more significant than that of the other two factors. Under the optimum pretreatment conditions (27% of the AS dosage (based on the dry wheat straw) at 160 ºC for 63 min), the final total sugar yield achieved was 74.4% after saccharification, which was in agreement with the predicted value (76.5%). Furthermore, it was found that pre-impregnation with acetic acid before AS pretreatment or the post-mechanical refining after AS pretreatment could further increase the fermentable sugar yields to approximately 77%. In addition, the spent liquor containing nitrogen could be used for the production of lignin-based fertilizer, thus making the whole process clean and sustainable.
Dewatering of softwood kraft pulp with additives of microfibrillated cellulose and dialcohol cellulose
Authors: Sjöstrand Björn , Barbier Christophe , Ullsten Henrik , Nilsson Lars
Published: March 2023

The addition of nano- and micro-fibrillated cellulose to conventional softwood Kraft pulps can enhance the product performance by increasing the strength properties and enabling the use of less raw material for a given product performance. However, dewatering is a major problem when implementing these materials to conventional paper grades because of their high water retention capacity. This study investigated how vacuum dewatering is affected by different types of additives. The hypothesis was that different types of pulp additions behave differently during a process like vacuum suction, even when the different additions have the same water retention value. One reference pulp and three additives were used in a laboratory-scaled experimental study of high vacuum suction box dewatering. The results suggested that there was a linear relationship between the water retention value and how much water that could be removed with vacuum dewatering. However, the linear relationship was dependent upon the pulp type and the additives. Additions of micro-fibrillated cellulose and dialcohol cellulose to the stock led to dewatering behaviors that suggested their addition in existing full-scale production plants can be accomplished without a major redesign of the wire or high vacuum section.
Factors affecting critical screw-driving torques in particleboard

Published: March 2023

Factors influencing the vertical driving force magnitude applied to screws during the process of driving the screws into faces of particleboard materials were investigated. In particular, the screw penetration depth and screwdriver air pressure were evaluated relative to critical torques, such as seating and stripping torques. Experimental results indicated that vertical driving forces significantly affected the magnitude of critical driving torques when no pilot hole was drilled, but this influence became non-significant when 3.2-mm diameter pilot holes were drilled. Screw-driving power had no significant effect on the magnitude of critical driving torques in particleboard materials if no pilot hole was drilled, but if pilot holes were drilled, increasing the screwdriver air pressure from 0.45 to 0.62 MPa led to increases in stripping torques. Increasing the screw penetration depth from 12.7 to 19.1 mm can significantly increase seating and stripping torques.
Multidisciplinary Research in Late Bronze Age Kukuliškiai Settlement (Klaipėda District): Methods and Primary Results
Authors: Urbonaitė-Ubė Miglė
Published: March 2023

The aim of this article is to present the most important results of the archaeological research of the Kukuliškiai settlement (Klaipėda district) in 2017–2020. During 3 seasons of the research, more than 3 hectares of the territory on the Littorina sea terrace were scanned by GPR, 101 geological drills were hammered, and an area of 45m2 was investigated. Fifteen AMS 14C dates were taken from different objects and stratigraphic layers of the settlement. Dating showed that settlement was contemporaneous and occupied around c. 800–400 cal BC. The complexity and scope of the research provides valuable insights into the lifestyle of Late Bronze Age coastal community. The discovery of wooden structures, organic artefacts and ecofacts indicates that the site provides excellent conditions for the survival of organics, of which there are only a dozen in Lithuania. The site and the collected research data, therefore, offer exceptional opportunities for the study of Bronze Age life not only in the coastal Lithuanian, but also in the southeastern Baltic region.
Rings of Power or in Search of Early Elites
Authors: Manzura Igor
Published: March 2023

The article discusses the problem of identification of prehistoric elites on the example of the Usatovo culture. Archaeological evidence allows us to discern in the culture three separate strata or classes which are conditionally designated as the Nobles, the Honoured, and the Commoners. Social elite represented a core within the noble class. It is distinguished by specific attributes which illustrate its attempts to resolve one of the most complex problems of any elite – to reconcile tension between “universalism” and “particularism”. The first quality is realized in ritual performance through manipulation of material objects whereas the second one is realized by means of sumptuary customs along with other methods. The emergence of the elites in the Usatovo culture became possible due to specific combination of objective factors which were successfully utilized by new social leaders.
Detection of Atrial Fibrillation in Patients Admitted with Ischaemic Stroke: A Non-systematic Review of the Asian Population

Stroke with AF is often associated with high recurrence rates. However, many patients with ischaemic stroke do not have a history of AF and show sinus rhythm and the absence of AF on their admission ECG. The detection of AF remains challenging due to its intermittent nature. Therefore, the ultimate goal of cardiac monitoring after cerebral ischaemic events is to detect AF so that oral anticoagulants can be prescribed to prevent the recurrence of a second, more debilitating or fatal stroke. In this article, AF detection in hospitalised patients with ischaemic stroke is discussed, with a focus on the Asian population. The AF detection rates in Asian cohorts are compared with those of major studies in the Western population; the utility and limitations of various cardiac monitoring modalities in Asian populations and healthcare systems and emerging technologies that could potentially detect AF in the stroke population are summarised and clinical practice and evidence gaps in detecting AF to prevent stroke recurrence are discussed.
Deep dive into beggar-thy-neighbour effects of monetary policy spillovers
Authors: Adámek Emil , Jursa Lukáš
Published: March 2023

We analyse the effect of the European Central Bank's (ECB) monetary shock spillover and its impact on the European Union's 9 countries outside the euro area (EA) between 2000 and 2020. We use the sign-restricted Bayesian VAR model and subsequent interpretation by plotting the impulse-response functions. Moreover, we investigate both conventional and unconventional monetary policies and its international transmission. The spillover of monetary policy is growing with the openness of economies and the ongoing deepening of integration. The output responds to the EA's monetary shock flexibly and persistently, but there is considerable heterogeneity across countries. We claim that it is essential for central banks outside the EA to monitor and incorporate the ECB's monetary policy spillover into decision-making processes. In particular, the international transmission of the unconventional monetary policy has a fundamental effect on the development of the price level, thus achieving price stability. In the case of implementing a counter-cyclical policy, it is also necessary to monitor conventional policy. However, there is no need to fight the spillover effect since there is no beggar-thy-neighbour problem, i.e., spillover effect works in the same direction in both domestic and foreign country.
Towards a set of indices for relational economy on the example of Hungary
Authors: Madlovics Bálint , Magyar Bálint
Published: March 2023

While informal relations between economic and political actors are prevalent in post-communist economies, proper tools for their quantitative measurement are lacking. This paper is a starting point for thinking about this issue. Relying on previous research (Magyar – Madlovics 2020), we elaborate the concept of ‘relational economy,’ and discuss the problem of measuring its peculiar phenomena by existing direct and indirect data. Towards a set of indices for relational economy, we consider the use of proxies in three ways: (1) a radar chart composed of specific company data; (2) ‘moments of truth’ when property movements reveal an actor's de facto ownership status; and (3) ‘moments of truth’ when adoption to or exclusion from the informal patronal network is accompanied by a significant change in financial situation. Illustrations to each of the three methods are provided from the case of Hungary after 2010.
The Joint Effect of the Type of Stakeholder and Incentive on the Acceptance of Budgetary Slack. Observed Differences in the Hierarchy of Needs Indicated by Polish Management Accountants
Authors: Nowak Marta , Maruszewska Ewa Wanda
Published: March 2023

We aimed to investigate the joint effect of the type of incentive and stakeholder on the acceptance of budgetary slack and examine the rankings of the five needs in Maslow’s pyramid. Using experimental research we demonstrated that motivational incentive and type of stakeholder interacted to affect the acceptance of budgetary slack. Management accountants experiencing non-monetary incentives in a situation where internal stakeholders’ expectations can be met with budgetary slack, showed the highest acceptance of budgetary slack. Respondents not accepting budgetary slack as professional behaviour ranked higher the needs that are on the top of Maslow’s pyramid.
Por uma desobediência não-civil para além do direito
Authors: Matos Andityas Soares de Moura Costa , Lima Bárbara Nascimento de
Published: March 2023

Resumo Buscou-se no presente artigo realizar uma crítica às tradições teóricas clássicas da desobediência civil que apresentam um profundo esforço argumentativo para compatibilizar as ações desobedientes com o direito. Visando romper os limites impostos à desobediência civil por tais tradições, o presente estudo propõe uma abordagem da desobediência política, pautada por um viés libertário que compreende os movimentos desobedientes em ação fora da esfera institucional do direito.
Protestos: questão de políticas, não de polícia
Authors: Penido Ana , Kalil Suzeley
Published: March 2023

Resumo O artigo tem como objeto políticas públicas específicas para ambientes de protestos sociais com vistas a evitar violações de direitos humanos. Parte-se do princípio de que o direito de protesto é um direito humano fundamental, e de que eliminar os protestos sociais é impossível e, acrescenta-se, indesejável. A metodologia escolhida foi a análise das normativas e recomendações internacionais a respeito do tema à luz de literatura crítica. Seus resultados foram organizados em cinco tópicos para a construção de normativas em nível nacional: necessidade de autorização prévia para a realização; responsabilidade dos organizadores; participação de grupos marginalizados politicamente; atuação dos comunicadores; medidas para e sobre a atuação das forças de segurança. Em sua conclusão, o artigo oferece 40 boas medidas sintetizadas das formulações internacionais.

Authors: Costa Ramon Silva , Gagliardi Marília Papaléo , Torres Livia Pazianotto
Published: March 2023

Abstract This article addresses the possibility of classifying gender identity as sensitive data, taking into consideration the parameters of Law 13.709/2018 and the queer theory. It presents a literature review and a documental analysis of terms from social networks. As a result, gender identity must be understood as sensitive data due to the vulnerability of non-cisgender people.

Resumo O artigo problematiza o capitalismo climático a partir dos resultados da pesquisa-ação desenvolvida junto ao Coletivo de Justiça Climática da Via Campesina (2014-2019) e a Comunidade Agroflorestal José Lutzenberger (Antonina/PR, 2016-2020). Como resultados aponta-se que os povos e movimentos sociais, enquanto grupos de alta vulnerabilidade à mudança do clima, também atuam como guardiões da biodiversidade, sendo importantes agentes sociais para a transição ecológica na perspectiva da justiça climática-ambiental.
Cidades criativas e a agenda internacional das políticas turístico-culturais de renovação urbana
Authors: Couto Bruno Gontyjo do
Published: March 2023

Resumo Nas últimas décadas, categorias como “cidades criativas” e “distritos criativos” ganharam espaço na agenda tanto de universidades quanto de governos e organizações internacionais, propondo uma nova forma de pensar a política urbana que combina planejamento urbano, desenvolvimento, artes, cultura e turismo. O presente artigo procura analisar historicamente os processos de surgimento e disseminação dessa racionalidade político-discursiva que está na base de uma nova agenda internacional para as cidades. O foco está posto na reconstituição da rede sociodiscursiva envolvida na consagração dos setores criativos como estratégia de desenvolvimento urbano e como peça fundamental dos projetos de renovação urbana adotados no mundo todo.
