A biliary stricture is an abnormal narrowing in the ductal drainage system of the liver that can result in clinically and physiologically relevant obstruction to the flow of bile. The most common and ominous etiology is malignancy, underscoring the importance of a high index of suspicion in the evaluation of this condition. The goals of care in patients with a biliary stricture are confirming or excluding malignancy (diagnosis) and reestablishing flow of bile to the duodenum (drainage); the approach to diagnosis and drainage varies according to anatomic location (extrahepatic vs perihilar). For extrahepatic strictures, endoscopic ultrasound-guided tissue acquisition is highly accurate and has become the diagnostic mainstay. In contrast, the diagnosis of perihilar strictures remains a challenge. Similarly, the drainage of extrahepatic strictures tends to be more straightforward and safer and less controversial than that of perihilar strictures. Recent evidence has provided some clarity in multiple important areas pertaining to biliary strictures, whereas several remaining controversies require additional research. The goal of this guideline is to provide practicing clinicians with the most evidence-based guidance on the approach to patients with extrahepatic and perihilar strictures, focusing on diagnosis and drainage.

Authors: Berger Benjamin T. , Townsend Matthew J. , Arbogast Mitchell K. , Van Kirk Jenny
Published: March 2023

Mucormycosis is an invasive fungal infection due to molds in the order Mucorales. These opportunistic pathogens found in soil or decaying organic matter mostly affect immunocompromised hosts. Rhino-orbital-cerebral, pulmonary, gastrointestinal, cutaneous, and disseminated patterns are possible. We describe a case of angioinvasive colonic mucormycosis in a patient with recent diabetic ketoacidosis and undiagnosed colon adenocarcinoma. The diagnosis was made on histopathology after the patient developed intestinal ischemia and underwent hemicolectomy. This case highlights the potentially diverse manifestations of Mucorales infections, typical and atypical risk factors, and the index of suspicion necessary for early diagnosis and outcome optimization.
Supporting teachers in safeguarding against harmful sexual behaviour: service providers’ perspectives on transformative practices
Authors: Draugedalen Kjersti
Published: March 2023

Sexual abuse of children is a growing public health issue, with a substantial proportion of such abuse carried out by other children and young people. Schools and teachers are uniquely placed to prevent and intervene against harmful sexual behaviour (HSB) among children and young people. Yet, for schools to safeguard effectively, they are reliant on cooperation with a range of children’s services. This study forms part of a wider research project exploring teachers’ safeguarding role. It identifies two emerging issues critical in interpreting the data and developing sound safeguarding processes: recognition of the role of professionals’ emotional reactions in addressing HSB and the impact of asymmetrical power relations. Building on Draugedalen and Osler’s theorisation of teachers’ safeguarding, this article examines front-line service providers’ perspectives on how they can support schools’ safeguarding, proposing a holistic structure of transformative practices that addresses emotions and asymmetrical power relations.

Authors: Oliveira Núbia dos Santos , Lellis Irani lauer , Barillas Maria Daniela Guzman
Published: March 2023

As crenças guiam as práticas docentes, inclusive no âmbito da alfabetização econômica. Este estudo objetivou compreender as crenças e práticas de docentes atuantes na educação infantil sobre alfabetização econômica-AE. Participaram duas docentes, que atendem crianças de 4 a 5 anos de um Centro Municipal de Educação Infantil, em Santarém – Pará. Utilizou-se roteiro de entrevista semiestruturada e analisou-se mediante a técnica do Discurso do Sujeito Coletivo – DSC. Os resultados apontaram para um incipiente conhecimento sobre AE, pois, as crenças manifestadas sobre AE limitaram-se ao senso comum; evidenciaram-se práticas que se limitam ao diálogo sem ações intencionais e sistematizadas. Infere-se que uma das premissas do presente estudo reside na importância da inserção da temática AE no currículo escolar, contribuindo na ampla exploração das crenças e práticas docentes. Para tanto, o investimento na formação docente seria necessário, contribuindo, portanto, no desenvolvimento integral da criança.

Published: March 2023

With the increase of reliance of LNG for Thailand, tons of liquefied natural gas (LNG) are imported, however there is no report that describes the engagement by a mathematical model. This study constructed a mathematical model to analyze LNG supply of Thailand. Based on the outcome in 2022, the offered LNG supply pattern, which reduced the total LNG price, risk of politics and risk of maritime, exhibited that Malaysia, Brunei, and Australia are LNG exporter of Thailand. Additionally, when the demand of LNG in Thailand increase, the demand from Qatar does not increase due to the low competitiveness. Moreover, in the study of diversification, the details suggested the raking of suppliers that Thailand should import. The rank is as follows: Brunei, Malaysia, Australia, USA, and Trinidad & Tobacco. The study of the objective factors on the decision of Thailand shows that the risk associated with shipping is ineffective to Thailand’s LNG supply due to the geographical closeness of the supplier countries. However, the risk connected to the political of supplier nations is influenced by the decision of the supply. Furthermore, this study revealed the limitation of the research associated with the LNG supply of Thailand. Hence, the finding of this study not only presented the alternative policy of Thailand but also consolidated Thailand’s energy security.

Optimized infrared-assisted extraction to obtain total lipid from microalgae Scenedesmus obliquus: a green approach
Authors: Correa-Aguado Hans Christian , Cerrillo-Rojas Gloria Viviana , Aguilera Flores Miguel Mauricio , Castillo Sergio Zavala , Morales-Domínguez José Francisco
Published: March 2023

Microalgae oil has great potential to address the growing energy demand and dependence on fossil fuels. However, the multilayered cell walls of microalgae hinder efficient extraction and enhanced lipid recovery. In this study, we develop a novel protocol based on near infrared-assisted extraction (NIRAE) technology to extract efficiently total lipids from Scenedesmus obliquus. Under a greener solvent extraction approach, the effect of nine non-polar/polar solvent systems in various ratios on lipid yield was tested, and the results were compared with Soxhlet, Folch, and Bligh–Dyer methods. The highest oil yields were NIRAE 15.43%, and Soxhlet 22.24%, using AcoEt/MeOH (1:2 v/v). For Folch and Bligh–Dyer, 9.11 and 10%, respectively. The optimized NIRAE conditions obtained using response surface methodology (RSM): 43.8 min, solvent/biomass 129.90:1 (m/v), and AcOEt/MeOH 0.57:2.43 (v/v) increased the oil yield significantly to 24.20%. In contrast to conventional methods, the overall optimized NIRAE process satisfied the requirements of a green extraction because of the simple and safe operation, less solvent toxicity, lower extraction time, and solvent and energy consumption.
Ethical issues in online interpreting training
Authors: Liu Hongyan , Lei Zhenhui
Published: March 2023

Although online education dissolves boundaries by providing “anywhere and anytime” teaching and learning opportunities, ethical concerns and challenges still exist. Interpreting training is preferably achieved in a face-to-face setting, as it concentrates on individual practice within an authentic interpreting environment for skill development rather than mere knowledge acquisition. This study examines ethical challenges and concerns in online interpreting training, including equality of learning outcomes, emotional support, privacy and audio/video data protection, and misconduct behaviours. Based on the observation of such ethical concerns, possible solutions for addressing such issues in the context of online interpreting training are explored. We suggest developing professional interpreting learning platforms and software, adopting virtual reality technology, compiling a multimodal corpus, and establishing a virtual community to achieve better learning outcomes.
Power in Global Governance: Power without Rulers?
Authors: Cruz Ortiz de Landázuri Manuel
Published: March 2023

Is there global governance beyond the State? What kind of power emerges in a global arena? In contrast to the neorealist position, which stresses the role of states in the constitution of international power, many Foucauldian interpretations have emerged that emphasize the role of power networks that are constituted through an episteme. In this article I will focus on global governance through a Platonic notion of power and the relationship Plato establishes between the power of norms and rules. I argue that global governance should be understood as a network of power with different intermediations, based on a global constitution taken as a cognitive frame behind the international legal order. In this sense, new forms of power appear, and are different from the traditional state power activity, based on settled practices and norms. My main thesis is that there can be power without a clear ruler, but there is no power without rational order (based on norms, dispositions, and communicative intermediations), therefore, I examine which kind of rational order appears in global governance in accordance to Plato’s account of power and some remarks recently made by Byung-Chul Han.

Published: March 2023

Distinct properties that nanomaterials possess compared to their bulk counterparts are attributed to their characteristic high surface area to volume ratios, and the prevalence of structure and shape effects at the nanoscale. However, these interesting properties are also accompanied by health hazards that are not seen in bulk materials. In the context of Philippine research and industry, the issue of nanosafety and the creation of nanotechnology guidelines have long been overlooked. This is of particular importance considering that nanotechnology research in the Philippines leans heavily towards medicinal and agricultural applications. In this study, nanomaterial samples from the industry submitted through the Philippine Industrial Technology Development Institute (ITDI) were analyzed using XRD and MTT cytotoxicity assay. XRD results show significant band broadening in the diffraction patterns of halloysite nanoclay, bentonite nanoparticles, silver nanoparticles, and CaCO3 nanoparticles, indicating that samples were in the nanometer range. The diffraction pattern of TiO2, however, did not exhibit band broadening, which may be due to the tendency of TiO2 nanoparticles to aggregate. Submitted samples were also assessed for their effect on cell viability using MTT cytotoxicity assay. Among these samples, only silver nanoparticles exhibited cytotoxicity to the AA8 cell line.
Surveys of Plastics in Post-1950 Non-published Book Collections
Authors: Chu Cancy , Barrett Melanie , Bunn Sarah , Zilio Francesca , Bell Julianne , Nel Petronella
Published: March 2023

Research over the past three decades has demonstrated that certain plastics in cultural materials are inherently unstable, displaying short lifespans and accelerating the degradation of neighbouring collection materials. Knowledge of the conservation of plastics is increasingly common in museum settings. However, less information is available on conserving plastics found in paper-based collections, and even less guidance on the materials and deterioration of plastic components found in book and document bindings. As plastics have been present in popular bookbinding materials since the mid-twentieth century, collection care professions require knowledge and methods for preserving these materials entering book collections. The aim of this paper is to determine strategies for the care of post-1950s books containing plastic. Collection surveys were conducted to determine the materials, structures, and degradation patterns of non-published books found in archive and archive-like settings at the South Australian Museum, the Art Gallery of New South Wales, and the Grimwade Centre for Cultural Materials Conservation at the University of Melbourne. A methodology combining condition reporting and infrared spectroscopy identified six plastic polymers in 35 binding styles that are summarised as 10 binding types. Recommendations are made for the use of preventive storage strategies responding to four categories of damage.
Estimation and testing of the factor-augmented panel regression models with missing data
Authors: Xiao Difa , Wang Lu , Wu Jianhong
Published: March 2023

This paper focuses on the factor-augmented panel regression models with missing data and individual-varying factors. A so-called CCEM estimator for the slope coefficient is proposed and its asymptotic properties are investigated under some regularity conditions. Furthermore, a joint test statistic is constructed for serial correlation and heteroscedasticity in the idiosyncratic errors. Under the null hypothesis, the test statistic can be shown to be asymptotically chi-square distributed. Monte Carlo simulation results show that the proposed estimator and test statistic have desired performance in finite samples.

The chemical bath deposition approach was used to arrange PbS and PbS coated with Ag thin layer thin films. PbS film was deposited at room temperature using thiourea and lead chloride as precursors. After the PbS film had been deposited, it was immersed in Ag precursors for 60 minutes at 50 C to coat its surface. In this study, we looked at absorbance in the 400-1000 nm range. The direct and indirect bandgaps were estimated using the Tauc method and yielded values between 1.3 and 1.45 eV. It resulted in increasing in bandgaps after coating with of Ag layer.

This study aimed to determine the effect of Al-doping on the physical properties of ZnS thin films. The pulsed-laser deposition technique was used to prepare ZnS and Al-doped ZnS (AZS) thin films on soda-lime glass slides. The Al concentration of 0–6% was used. Further, XRD spectroscopy was employed to confirm the structures of the ZnS and AZS films, following which the values of parameters such as crystal plane spacing, crystallite grain size, microstrain, and dislocation density were calculated. Regarding ZnS, the result showed a broad pattern corresponding to the (111) plane of ZnS. There was a variation of 0.313–0.316 nm in the d-spacing, which decreased as the concentration of Al in the ZnS films increased. The crystallite size was found to be 0.80–671.24 nm. Notably, the crystallite size was affected by the Al concentration. The change in the a aluminum content from 0 to 8% make change in thee strain increase from 0.00046 to 0.0031. Also, as the Al-doping increased, the dislocation-density reduced from 1.54 to 0.00000221 mg.cm-3 . The values obtained in this work were consistent with published standards.
Riječka lutkarska scena i poljsko lutkarstvo
Authors: Verdonik Maja , Riman Kristina
Published: March 2023

Uvidom u dostupne izvore i arhivsku građu u radu se propituje utjecaj poljskog lutkarstva i poljskih umjetnika – autora tekstova i redatelja lutkarskih predstava – na suvremeno hrvatsko lutkarstvo tijekom druge polovice 20. stoljeća. Igrokazi poljskih književnika izvođeni su u hrvatskim lutkarskim kazalištima 60-ih godina 20. stoljeća kao rezultat formiranja tadašnje repertoarne politike pri čemu je osobito zapažena bila suradnja zadarskog Kazališta lutaka i poljskih autora i redatelja, posebice Wiesława Hejna. U povijesti djelovanja današnjeg Gradskoga kazališta lutaka Rijeka važan je trag ostavilo gostovanje poljskih lutkara u Opatiji (u neposrednoj blizini Rijeke) i riječkih u Poljskoj i Slovačkoj tijekom 60-ih godina 20. stoljeća. Tom su prigodom riječki lutkari upoznali tada avangardne lutkarske predstave u formi tzv. kazališta različitih izražajnih sredstava u kojima su uz lutke nastupali glumci te lutkarske predstave za odrasle, što je imalo utjecaja na repertoar ovog kazališta u kasnijim razdobljima. Od tekstova poljskih autora u tadašnjem Kazalištu lutaka Rijeka krajem 60-ih godina kao klasične lutkarske predstave izvođeni su igrokazi Klub lažnih detektiva Ryszarda Raduszewskog i Vuk i kozlići Jana Grabowskog, a krajem 80-ih u formi kazališta različitih izražajnih sredstava igrokaz Małgorzate Jokiel Mala krila.

Članak donosi pregled prostorne organizacije biskupijskog uređenja u Bosni i Hercegovini stavljajući ga, u užem smislu, u kontekst geopolitičkih razmatranja. U širem smislu, promatrajući ga s aspekta uloge Vatikana i Katoličke Crkve u geopolitičkoj konfiguraciji Balkana, članak kontekstualizira ovo prostorno uređenje u odnosu na širi regionalni i europski kontekst. U teorijskom smislu, članak zadire u teorijske aspekte političke geografije i geografije religije. U metodološkom smislu, članak inicijalno objašnjava povijesni kontekst nastanka prostorne organizacije biskupija u Bosni i Hercegovini. Nadalje, na temelju podataka iz popisa stanovništva, članak istražuje i kartografski interpretira odstupanja između granica biskupija i prostora naseljenima Hrvatima kao jedinim većinski katoličkim konstitutivnim narodom u Bosni i Hercegovini. Konačno, članak potvrđuje hipotezu prema kojoj je, za razliku od etničkog pristupa, geopolitički pristup bio presudan u prostornoj organizaciji Katoličke Crkve u Bosni i Hercegovini.
Alternativna i augmentativna komunikacija u kontekstu učenja stranog jezika kod djece predškolske dobi
Authors: Kotlar Manuela
Published: March 2023

Rad skreće pozornost na moguću korist od implementacije relativno nove kombinirane komunikacijske tehnike u glotodidaktičke metode rada s djecom predškolske dobi. Riječ je o čitanju priča prevedenih u simbole (PCS, WLS ili Bliss) koje se koristi u sklopu augmentativne i alternativne komunikacije (AAK) u radu s osobama s posebnim komunikacijskim potrebama. Prijedlog se temelji na rezultatima znanstvenih istraživanja vezanih za važnost čitanja priča djeci, posebice u prvim godinama života, te znanstvenim istraživanjima vezanima za upotrebu knjiga prevedenih u AAK simbole u radu s osobama s posebnim komunikacijskim potrebama. S obzirom na to da u prvim godinama učenja stranog jezika, bez obzira na dob, neminovno dolazi do nesrazmjera između intelektualnog nivoa i interesnih sfera djece s jedne strane i stupnja njihovog poznavanja stranog jezika s druge strane, nastavnici i odgojitelji često se nalaze pred izazovom pronalaženja adekvatnih materijala jer razumljivi tekstovi djeci najčešće nisu zanimljivi, dok im oni koji bi im mogli biti zanimljivi nisu razumljivi. To posebice dolazi do izražaja u predškolskom uzrastu, jer u toj dobi djeca ne ulaze u proces učenja stranog jezika svjesno i s namjerom, stoga je jako važno pobuditi im adekvatan interes za nastavni materijal. U radu se razmatra moguća višestruka korist od čitanja priča prevedenih u simbole i predlaže provedba konkretnih istraživanja u praksi.
Outcome and prognostic factors for pituitary carcinomas: lessons from a systematic review
Authors: Raymond Perrine , Raverot Gérald , Ilie Mirela-Diana
Published: March 2023

Purpose

The purpose of this work was toinvestigate the clinicopathological characteristics at the initial diagnosis of the pituitary tumor and at pituitary carcinoma (PC) diagnosis, alongside with the management and outcomes of PCs, and identify potential prognostic factors and therapeutic strategies associated with the clinical outcome.

Methods

PubMed was searched in May 2021 for articles in English and French reporting PCs, the diagnosis of which was made on the presence of metastases. The cases without histological proof and with either another cancer present or an atypical history for a pituitary tumor were excluded.

Results

One hundred and eighty-one articles reporting 207 cases were included, which included 38% corticotroph and 29% lactotroph carcinomas. An initial Ki67 index ≥10% was associated with shorter survival after the initial diagnosis (P = 0.01). Cases with early metastases were associated with both higher initial Ki67 index (P = 0.01) and shorter survival after PC diagnosis (P = 0.001). Interestingly, cases with short survival after PC diagnosis were associated with shorter time between the initial diagnosis and PC diagnosis (P = 0.0006) and had both higher initial Ki67 index (P = 0.003) and higher Ki67 index of the metastasis (P = 0.03). In addition, cases with long survival after PC diagnosis had received more frequently both systemic treatment after PC diagnosis (P = 0.0005) and local treatment for metastases (P < 0.0001).

Conclusions

An initial Ki67 index ≥10% is associated with worse outcome and appears as a promising early marker of future metastasis. Its presence should lead to an intensified surveillance and to a more timely management. Clinicians should not hesitate to use local treatment, independent of whether systemic treatment is used.

Entre la tradición y la modernidad: los manuales de teología moral de la Compañía de Jesús y la obra de Juan Azor
Authors: Martín López David
Published: March 2023

La Compañía de Jesús tuvo un importante papel en la cultura y la sociedaddel Barroco español. Analizadas en su conjunto las obras jesuitas publicadas entre finales del siglo XVI y las primeras décadas del XVII, observamos una serie de características y enfoques que unen la tradición bajomedieval con la modernidad. La casuística y la dirección de conciencias fueron los ámbitos más prolijos en el desempeño de su actividad misional, pero no el único en el que se pudo observar esa situación intermedia. Los enfoques educativos con tintes humanistas, así como una teología moral que recordaba en algunos puntos a obras de los siglos XIV y XV nos llevan a pensar en esa complejidad y a reformular el papel de los ignacianos únicamente como modernizadores de la moral y elcomportamiento católico después de Trento.

ZIRCON ANATOMY FROM THE ROCKS ASSOCIATION OF THE OSTRIVSKY QUARRY (ROS-TIKYCH MEGABLOCK OF THE UKRAINIAN SHIELD)
Authors: Stepanyuk L.M. , Yaskevich T.B. , Kotvitska I.M.
Published: March 2023

Granitoids play a key role in the geological structure of the Ros-Tikych megablock. Supercrustal rocks of the Ros-Tikych series have been preserved in the granitoids only in the form of isolated fragments such as elongated remains, small skialites and even smaller "melted" xenoliths. In particular, in the Ostrivsky quarry, located on the right bank of the Ros River east of Bila Tserkva, granitoids are found (even-grained, porphyry-like granites) among which, as a rule, small bodies of granodiorites, plagiogranites and amphibolites occur. In order to determine the source of the parent magmas of rocks the properties of zircon crystals and the isotopic composition (87Sr/86Sr ratio) of apatite were studied. An analysis of the zircon crystals of the crystalline rocks exposed at the Ostrivsky quarry allows us to propose that the and plagio- and difeldspar granites were formed from one protolith. This is because they contain similar virtually identical zircon relics as nucleus. In addition, none of the granitoids contain zircon crystals whose internal structure is similar to zircon crystals found in amphibolite. This suggests that the granitoids were not derived by melting of amphibolites. Most likely, amphibolites are relicts of the protolith that were not assimilated during granite formation. The occurrence of heterogeneous zircon crystals (relic zircon cores of the protolith) in the protolith of the various studied granitoids indicates that they formed from volcanic-sedimentary rocks. Apatites in plagiogranitoids and porphyry granite contain strontium of similar isotopic composition. Their 87Sr/86Sr isotopic ratio is 0.70680 in apatite granodiorite and 0.70822 in granite. A high ratio of 87Sr/86Sr = 0.77940 was measured for apatite from monazite-bearing granite, thus indicating a different source for its parent magma.
'Pill-in-the-pocket’ Oral Anticoagulation Guided by Daily Rhythm Monitoring for Stroke Prevention in Patients with AF: A Systematic Review and Meta-analysis

Published: March 2023

Aims: In patients with a low AF burden and long periods of sinus rhythm, ‘pill-in-the-pocket’ oral anticoagulation (OAC) may, taken as needed in response to AF episodes, offer the same thromboembolic protection as continuous, life-long OAC, while reducing bleeding complications at the same time. The purpose of this study is to systematically summarise available evidence pertaining to the feasibility, safety and efficacy of pill-in-the-pocket OAC. Methods: Medline and Embase were searched from inception to July 2022 for studies adopting a pill-in-the-pocket OAC strategy in AF patients guided by daily rhythm monitoring (PROSPERO/CRD42020209564). Outcomes of interest were extracted and event rates per patient-years of follow-up were calculated. A random effects model was used for pooled estimates. Results: Eight studies were included (711 patients). Daily rhythm monitoring was continuous in six studies and intermittent in two (pulse checks or smartphone single-lead electrocardiograms were used). Anticoagulation criteria varied across studies, reflecting the uncertainty regarding the AF burden that warrants anticoagulation. The mean time from AF meeting OAC criteria to its initiation was not reported. Adopting pill-in-the-pocket OAC led to 390 (54.7%) patients stopping OAC, 85 (12.0%) patients taking pill-in-the-pocket OAC and 237 (33.3%) patients remaining on or returning to continuous OAC. Overall, annualised ischaemic stroke and major bleeding rates per patient-year of follow-up were low at 0.005 (95% CI [0.002–0.012]) and 0.024 (95% CI [0.013–0.043]), respectively. Conclusion: Current evidence, although encouraging, is insufficient to inform practice. Additional studies are required to improve our understanding of the relationships between AF burden and thromboembolic risk to help define anticoagulation criteria and appropriate monitoring strategies.

Aim of the study: i. Comparison of characteristic discharges (mean and mean of annual minimum, i.e. mean low discharge) of small lowland river between two periods (1963-1990 and 1991-2020) estimated on the base of field measurements. ii. Comparison of specific discharges of two small catchments of various size in the period 1991-2020. iii. Evaluation of local indirect methods for estimation of mean and mean low discharge applied for the two small catchments. Material and methods: Since 1962, hydrological investigations have been conducted in a small lowland catchment of the Zagożdżonka River. The catchment area is characterized by agro-forested land use, and is located in the south part of the Masovia region, Poland. Continued monitoring of water stages and discharge measurement at the river gauge Płachty Stare were conducted for estimating daily and characteristic discharges for two periods: 1963-1990 and 1991-2020. Other methods were also used for both of the hydrological characteristics. They were based on maps of specific discharges from the Hydrological Atlas of Poland. Results and conclusions: Mean discharge of the Zagożdżonka River at the gauge Płachty Stare between the two periods decreased by 24%. Mean low flow decreased by 43%. Higher evapotranspiration, caused by climate change, i.e. temperature increase and higher ratio of forested area in the catchment, is indicated as the main reason of the changes. Mean specific discharge from the smaller catchment (at Wygoda gauge) was 36% less than from the larger catchment. The application of the indirect methods for estimation of mean and mean low discharges for the larger catchment seems to give satisfactory results.

Jesus and Addiction to Origins: Toward an Anthropocentric Study of Religion
Authors: Braun Willi
Published: March 2023

This collection of essays constitutes an extended argument for an anthropocentric, human-focused study of religious practices. Part I presents the basic premise of the argument, which is that there is nothing special or extraordinary about human behaviors and constructs that are claimed to have uniquely religious status and authority. Instead, they are fundamentally human, and so the scholar of religion is engaged in nothing more or less than studying humans across time and place in all their complex existence—which includes creating more-than-human beings and realities. As an extended and detailed example of such an approach, Part II addresses practices, rhetoric, and other data in early Christianities within Greco-Roman cultures and religions. The underlying aim is to insert studies of the New Testament and non-canonical texts, most often presented as “biblical studies,” into the anthropocentric study of religion proposed in Part I. How might we approach the study of “sacred texts” if they are nothing more or less than human documents deriving from situations that were themselves all too human? Braun’s Jesus and Addiction to Origins addresses that question with clarity and insight.

Published: March 2023

We describe a thorough study of the wave-mixing procedure in the extreme ultraviolet (XUV) region involving three laser fields (800 nm, 1400 nm and 1860 nm). In addition to the phase matched HHG spectrum generated by an 800-nm laser (driving field), non-integer order wave-mixing spectra are produced when the driving field and the control field (1400 nm or 1860 nm) are collinearly focused into krypton gas. In addition, the simultaneous presence of three laser fields generates resolvable four-wave mixing (FWM) frequencies that clearly indicate the contribution of each control field. We also discuss an application of the FWM scheme to extend the HHG cutoff region and generate the XUV quasi-continuum spectrum.

Published: March 2023

Excessive salt consumption has been found to cause many negative effects on human health. To date, many researches have been conducted to reduce the sodium content of the diet. This study focused on the comparison of saltiness intensity and other parameters in time-intensity curves of four commercial grain salts in four regions of Viet Nam (Bac Lieu, Thanh Hoa, Sa Huynh, Vung Tau), one flower salt in Sa Huynh and a control sample with two particle sizes of 1-2 mm and 2-3 mm to find out their taste perception characteristics. A modified sensory evaluation technique focusing on time-intensity was used to train a panel to evaluate the temporal profile of saltiness of salt crystals. The results showed a significant difference in the perception ability and time intensity of saltiness in salt products by region and particle size. Sensory measures exhibited the differences in the specificity of salt samples by region and a strong correlation with their physical properties. Sa Huynh flower salt and sea salt showed different characteristics compared to other salt samples with higher intensity of salty taste, faster time to reach the maximum intensity, and shorter duration of salt taste intensity. These results demonstrated that flower salt could reduce the level of sodium intake while maintaining the saltiness perception in products, which is a potential ingredient in food, spices, etc.
Evaluation of groundwater level, quality and recharge: a case study of Can Tho City, Viet Nam

Published: March 2023

This study evaluated the groundwater levels (GWLs) and groundwater quality of Can Tho city (CTC) using statistical analysis and a Groundwater Quality Index (GWQI). In addition, the groundwater recharge potential from rainfall was investigated for the period 2001-2009. The results show that GWLs decreased rapidly in the period 2000-2010 and gradually in the period 2012-2018 in both the Middle-upper Pleistocene (qp2-3) and Upper Pleistocene (qp3) aquifers. This is due to excessive withdrawals, especially to meet the demands of production facilities in the city’s industrial zones. In this regard, Decree No. 2946/UBND-KT of the People’s Committee of CTC was issued and enacted in 2012, which resulted in a marked reduction in withdrawals and contributed to GWL stabilization. Groundwater quality in CTC was found to be mainly affected by coliform in both dry and wet seasons. However, groundwater quality improved during the wet season with the dilution of rainfall, as shown by the GWQI values. In addition to groundwater recharge from rainfall, other socio-economic factors such as urbanization, industrialization, and the influence of the Bassac River on recharge potentials should be further investigated.

Published: March 2023

Urban heat island effects are an increasing challenge for metropolitan areas, especially in regions where climate change increases the frequency of extreme temperatures. The consequences for human health are understood and must be addressed by urban planning. Although many studies currently exist regarding relationships of adaptation measures and urban heat amongst individual single cities, there is little general understanding on how urban development impacts temperature at large scales. In this study we analyze the correlation between urban heat and two indicators of urban morphology: the green spaces and the density of buildings. We hypothesize that the relation between building density, urban green space and urban surface temperature can be quantified openly available techniques of Earth observation. To grant an objective and consistent analysis over the entire country of Vietnam, we use information from different high-resolution imaging satellites. The computation of Pearson correlations across 58 Vietnamese districts confirms the hypothesis, indicating a negative impact of urban green space (-0.217), a positive impact of building density (+0.392) and an even stronger relationship with both indicators combined (+0.435). The findings are discussed with data of three research projects involving the cities of Hồ Chí Minh, Đà Nẵng, and Huế, and interpreted regarding regional differences and implications for urban planning.

Published: March 2023

This paper presents the preparation and some characteristics of collagen/polyphenols materials containing different polyphenols contents. Collagen was extracted from fresh-water fish scales and polyphenols were extracted from Camellia chrysantha (Tam Dao, Vinh Phuc, Viet Nam). A comparison between these polyphenols and green tea polyphenols (commercial product) was carried out in this study. Functional groups and morphology of collagen/polyphenols materials were determined by Infrared spectroscopy (IR) and scanning electron microscope (SEM). Ultraviolet-visible spectroscopy (UV-Vis) was used to evaluate the release of polyphenols from collagen/polyphenols materials in simulated body fluids. In addition, the anti-oxidation ability of collagen/polyphenols materials was also investigated by 1,1-diphenyl-2-picryl hydrazyl (DPPH) radical scavenging method. The obtained results showed that polyphenols with the size of ca. 100 nm were dispersed and adhered well to the collagen matrix. The release of polyphenols from the materials follows two stages: fast release during the first 2 hours of testing and controlled release in the following hours. The content of polyphenols released from the collagen/polyphenols materials in pH 2.0 solution was higher than that in pH 7.4 solution. After 8 hours of testing, the content of polyphenols released from the collagen/polyphenols materials reached 15-65 % depending on the polyphenols content, type of polyphenols and pH of solution. The anti-oxidation ability of polyphenols extracted from Camellia chrysantha is better than that of green tea polyphenols and collagen/polyphenols materials.

Published: March 2023

We numerically study in this work the magnetic properties induced by the on-site electron-electron interaction in graphene nanoflakes shaped diamond with a variety of sizes. By the mean-field Hubbard approximation, a phase transition in analogy to infinite graphene from non-magnetism to antiferromagnetism is observed. A very weak interaction U, approximately zero, is reported to be able to trigger magnetic ordering in a finite nanoflake compared to infinite structure. Furthermore, the investigation also indicates the edge and size dependence of magnetism. The antiferromagnetic ground state is of robust stability to larger zigzag nanoflake size and stronger interaction. The phase transition point, Uc, is found to be sensitive to the size denoted by means of the reduction of Uc as the size increases. The important role of edge effect causing the spin polarization along zigzag termination is confirmed for the diamond nanoflakes.

Published: March 2023

Microfluidics has emerged in recent years as a technology that has advantages and is well suited for studying chemistry, biology, and physics at the microscale. A common material which has been widely use to fabricate the microfluidic system is thermoplastic materials. The method of fabricating microfluidic devices has been growing because of advantages such as high-quality feature replication, inexpensiveness, and ease of use. However, the major barrier to the utilization of thermoplastics is the lack of bonding methods for different plastic layers to close the microchannels. Therefore, this study focused on fabricating a microfluidic device on poly(methyl methacrylate) (PMMA) plates by laser engraving. The bonding technique for plastic layers has relied on the application of small amounts of ethanol with conditions of low temperatures (100 ⁰C), and relatively low pressures (5 tons) for 2 minutes. With this technique, the microfluidic device is created to operate stably, without leakage or cracking even under high pressure. The microfluidic device was applied to synthesize liposomes with a 5:1 ratio of syringe pump velocity between water and lipid solution. The size of liposomes after synthesis is 109.64 ± 4.62 nm (mean ± sd) and the PDI is in accordance with standard conditions (PDI < 0.200).
