A leading-order viscoelastic model for crevasse propagation and calving in ice shelves
Authors: Zarrinderakht Maryam , Schoof Christian , Zwinger Thomas
Published: June 2023

Abstract. We use a leading-order viscoelastic model for crevasse evolution, in which a purely viscous model for the deformation of the domain couples with linear elastic fracture mechanics models through a viscous pre-stress. The fracture mechanics model conversely couples with the viscous model by inserting cracks into the domain, which viscous flow subsequently pulls apart. By contrast with prior work, we solve the fracture mechanics problem on the actual domain geometry using a boundary element method, coupled with a finite element solution of the Stokes equations describing the viscous flow. We study a periodic array of surface and basal crevasses on an ice shelf being stretched at a prescribed rate. We find that calving can either occur instantly for large enough stretching rates or sufficiently high surface water levels or through feedbacks between partial fracture propagation and subsequent viscous deformation and adjustment of the viscous pre-stress acting on crack faces. Our results show that purely stress-based calving laws cannot robustly describe the process of calving, since they cannot account for the gradual evolution of local crevasse and surface geometry, which can be understood at the large scale as being more akin to the evolution of a damage variable. Future work will need to coarse-grain the type of process model we describe here in order to make it applicable to ice sheet simulations.

Abstract. The Alpha Jet Atmospheric eXperiment (AJAX) flew
scientific flights between 2011 and 2018 providing measurements of trace gas
species and meteorological parameters over California and Nevada, USA. This
paper describes the observations made by the AJAX program over 229 flights
and approximately 450 h of flying. AJAX was a multi-year,
multi-objective, multi-instrument program with a variety of sampling
strategies resulting in an extensive dataset of interest to a wide variety
of users. Some of the more common flight objectives include satellite
calibration/validation (GOSAT, OCO-2, TROPOMI) at Railroad Valley and other
locations and long-term observations of free-tropospheric and boundary layer
ozone allowing for studies of stratosphere-to-troposphere transport and
long-range transport to the western United States. AJAX also performed
topical studies such as sampling wildfire emissions, urban outflow and
atmospheric rivers. Airborne measurements of carbon dioxide, methane, ozone,
formaldehyde, water vapor, temperature, pressure and 3-D winds made by the
AJAX program have been published at NASA's Airborne Science Data Center (https://asdc.larc.nasa.gov/project/AJAXTS9 (last access: 1 November 2022), https://doi.org/10.5067/ASDC/SUBORBITAL/AJAX/DATA001,

A wind-driven snow redistribution module for Alpine3D v3.3.0: adaptations designed for downscaling ice sheet surface mass balance
Authors: Keenan Eric , Wever Nander , Lenaerts Jan T. M. , Medley Brooke
Published: June 2023

Abstract. Ice sheet surface mass balance describes the net snow accumulation at the ice sheet surface. On the Antarctic ice sheet, winds redistribute snow, resulting in a surface mass balance that is variable in both space and time. Representing wind-driven snow redistribution processes in models is critical for local assessments of surface mass balance, repeat altimetry studies, and interpretation of ice core accumulation records. To this end, we have adapted Alpine3D, an existing distributed snow modeling framework, to downscale Antarctic surface mass balance to horizontal resolutions up to 1 km. In particular, we have introduced a new two-dimensional advection-based wind-driven snow redistribution module that is driven by an offline coupling between WindNinja, a wind downscaling model, and Alpine3D. We then show that large accumulation variability can be at least partially explained by terrain-induced wind speed variations which subsequently redistribute snow around rolling topography. By comparing Alpine3D to airborne-derived snow accumulation measurements within a testing domain over Pine Island Glacier in West Antarctica, we demonstrate that our Alpine3D downscaling approach improves surface mass balance estimates when compared to the Modern-Era Retrospective analysis for Research and Applications, Version 2 (MERRA-2), a global atmospheric reanalysis which we use as atmospheric forcing. In particular, when compared to MERRA-2, Alpine3D reduces simulated surface mass balance root mean squared error by 23.4 mmw.e.yr-1 (13 %) and increases variance explained by 24 %. Despite these improvements, our results demonstrate that considerable uncertainty stems from the employed saltation model, confounding simulations of surface mass balance variability.
Constraining regional glacier reconstructions using past ice thickness of deglaciating areas – a case study in the European Alps
Authors: Sommer Christian , Fürst Johannes J. , Huss Matthias , Braun Matthias H.
Published: June 2023

Abstract. In order to assess future glacier evolution and
meltwater runoff, accurate knowledge on the volume and the ice thickness
distribution of glaciers is crucial. However, in situ observations of
glacier thickness are sparse in many regions worldwide due to the difficulty
of undertaking field surveys. This lack of in situ measurements can be
partially overcome by remote-sensing information. Multi-temporal and
contemporaneous data on glacier extent and surface elevation provide past
information on ice thickness for retreating glaciers in the newly
deglacierized regions. However, these observations are concentrated near the
glacier snouts, which is disadvantageous because it is known to introduce
biases in ice thickness reconstruction approaches. Here, we show a strategy
to overcome this generic limitation of so-called retreat thickness
observations by applying an empirical relationship between the ice viscosity
at locations with in situ observations and observations from digital elevation model (DEM) differencing at the glacier margins. Various datasets from the European
Alps are combined to model the ice thickness distribution of Alpine glaciers
for two time steps (1970 and 2003) based on the observed thickness in regions
uncovered from ice during the study period. Our results show that the
average ice thickness would be substantially underestimated (∼ 40 %) when relying solely on thickness observations from previously
glacierized areas. Thus, a transferable topography-based viscosity scaling
is developed to correct the modelled ice thickness distribution. It is shown
that the presented approach is able to reproduce region-wide glacier
volumes, although larger uncertainties remain at a local scale, and thus might
represent a powerful tool for application in regions with sparse
observations.

Paródia em Nikos Kazantzákis
Authors: Santos João Victor Rodrigues
Published: June 2023

Pretendemos voltar nossa atenção à produção narrativa de Nikos Kazantzákis (1883-1957), mais precisamente ao romance O Cristo recrucificado (1971), e investigar quais são os possíveis efeitos da retomada do discurso religioso pelo escritor. Para tanto, faremos uso de contribuições vindas do campo de estudo da Literatura Comparada, como as de Samoyault (2008) e as de Hutcheon (1985), autoras que se detiveram sobre assuntos como intertextualidade e paródia, respectivamente. Postulamos, diante disso, que O Cristo recrucificado pode ser lido sob a ótica de uma paródia (retomada com comentário crítico) da Paixão de Cristo, evento tornado público a partir dos “Evangelhos Sinóticos” de Mateus, Marcos, Lucas e João, na qual Kazantzákis faz uso intertextual de passagens bíblicas para sustentar sua crítica ao cristianismo estabelecido, representado pela Igreja Católica Ortodoxa e por suas autoridades, e enfatizar seu distanciamento dos ideais de Jesus Cristo, conforme trazido pelos Evangelhos.
Espólio de um poeta
Authors: Araujo Rodrigo Michell
Published: June 2023

Este artigo pretende analisar algumas correspondências pertencentes ao espólio do poeta e crítico Adolfo Casais Monteiro, manuscritos que estão atualmente afiançados na Biblioteca Nacional de Portugal, em Lisboa. O que buscarei evidenciar neste trabalho são algumas implicações que o apelo à sinceridade deixa na materialidade do corpus de Casais Monteiro. Procurarei, assim, compreender alguns elementos essenciais que estão em causa na relação profícua que o autor estabeleceu com o Brasil e com os poetas brasileiros. A partir do cotejo de algumas cartas de poetas como Manuel Bandeira e Drummond, elaboro a hipótese da viabilidade de um sentido ontológico da sinceridade, que é partilhada não só por Casais, como também pelos poetas com quem trocou correspondência. Com isso, sustentarei o argumento da viabilidade de uma mútua valorização da sinceridade como força vital, o que permite novas reflexões sobre as relações entre as literaturas portuguesa e brasileira, em um momento modernista de aparentes desencontros apontados pelos críticos.

O misticismo da poética muriliana em Poesia Liberdade (1947)
Authors: Alves Débora Mendes dos Santos
Published: June 2023

Entre os grandes nomes do Modernismo brasileiro destaca-se Murilo Monteiro Mendes, poeta mineiro, integrante da Segunda Geração Modernista (1930), que, em meio às transformações e as crises da modernidade, fez de sua poesia um instrumento de resistência. Dessa maneira, a retomada de valores, a angústia, a reflexão do indivíduo sobre o seu lugar no mundo e a aproximação com o divino são tônicas presentes em sua obra Poesia Liberdade (1947). A partir das teorias de O ser e o tempo da poesia (1977), de Alfredo Bosi; A cabala e seu Simbolismo (2015), de Gershom Scholem, O meio divino (2021), de Pierre Teilhard de Chardin, observamos as ligações entre Poesia e Mística, de modo a identificar os conceitos principais que versam tais áreas e a maneira com que os mitos e os símbolos cristãos influenciam o caráter místico da poética muriliana na busca pela unidade.
El conflicto entre filantropismo y humanismo y el lugar de la filosofía en el conjunto del saber
Authors: Mancebo Pérez Pilar
Published: June 2023

Partiendo de la constatación husserliana de la crisis filosófica como crisis vital de una humanidad que se ha desviado de su télos al implantar el modelo tecno-científico del dominio del mundo, el artículo investiga el lugar de la filosofía en el sistema educativo, explorando las reformas propuestas en Baviera y Prusia por Niethammer y Humboldt a principios del siglo XIX y que plantean, cada una a su modo, la necesaria incorporación de la filosofía a una educación de Estado que, frente a las pretensiones utilitarias del filantropismo, logre elevar al hombre a su humanidad. En este sentido, retorna al concepto humanista de formación (Bildung) al que se consagran ambas reformas y que Gadamer recupera precisamente en Verdad y método como un ideal para enfrentar la pretensión de universalidad de la ciencia moderna en relación a las nociones de conocimiento y de verdad, así como para pensar el horizonte ontológico de la experiencia hermenéutica. Es precisamente este ideal el que permite localizar el lugar de la filosofía en el conjunto del saber y conducir al hombre a su humanidad.
Information and communication technologies and China’s international communication to the world
Authors: Xiang Debao , Cai Weihan
Published: June 2023

Over four decades, ICT rapidly proliferated in China, transforming, and reshaping the country’s international communication in theory and practice. In parallel with economic achievements after the reform and opening-up, China aspires to enhance accordingly its international influence, thus requiring its media to emerge on the global stage. The article suggests that ICT plays a significant role in driving Chinese media’s global outreach, thereby enhancing soft power and improving its national image. Against the backdrop of continuous hegemony and unbalance in the global communication networks, the Belt and Road Initiative (BRI) launched by China aims to benefit developing countries in the Global South by constructing ICT infrastructures. Following the practice, the concept of a Community of Shared Future for Mankind was advanced to promote multilateral cooperation and better communication. China shoulders unprecedented responsibilities in an increasingly multipolar world where a new global communication order is expected.

The problem of energy storage and portable charging is addressed in this study with a green and affordable method. With the use of photovoltaic cells from discarded calculators, the study seeks to build a solar power bank. With the absorption of photons and the subsequent release of electrons, photovoltaic cells are devices that transform sunlight into electricity. They can power a variety of devices and are a clean, sustainable source of energy composed of materials like silicon. Proving its effectiveness, the efficiency rate of the power bank in charging a mobile device in various times was tested. The study proved that after 150 minutes, the device was charged from 0% to (100%). The research methodology involves the collection of discarded calculators, the dismantling of these calculators, and the extraction of their photovoltaic cells. The cells are then assembled and connected to maximize the energy output that can be used to charge batteries or portable devices. The study also examined the economic and environmental benefits of this approach. Utilizing a material such as the photovoltaic cell is a good way to reuse and recycle discarded materials or e-wastes. It was found that the cost of creating a solar power bank from discarded calculators is significantly lower than purchasing a new one. Furthermore, the ability to reuse discarded calculators reduces the amount of electronic waste and contributes to environmental sustainability. This study suggests that the use of discarded calculators as a source of photovoltaic cells has the potential to be implemented on a larger scale. In conclusion, this study demonstrates that photovoltaic cells from discarded calculators can be repurposed to create a solar power bank. This solution provides an environmentally friendly and cost-effective way of generating and storing electricity.
Optimasi pengelolaan sampah plastik melalui pendekatan edukatif dan pemberdayaan siswa SMP di Kecamatan Bangko Pusako Kabupaten Rokan Hilir
Authors: Riyana Olfa , Siregar Yusni Ikhwan , Putra Ridwan Manda
Published: June 2023

Even in the setting of schools, open burning of rubbish is still frequently practiced. This is in conflict with the government's program connected to the Pollution Control Strategic Plan (2020–2024), which has the goal of lowering greenhouse gas emissions, and the waste management policy (Law No. 18 of 2008). The justification is that the waste cannot be carried to the TPS or TPA, preventing it from building up and having negative effects like pollution. Lack of awareness, bad habits, and the idea that burning trash is simple and inexpensive are the causes. This issue also exists in SMPN 1 and SMPN 5, Bangko Pusako District, where waste is still managed conventionally by burning it all together without sorting it (visually, 40% of the waste is plastic). The quantity of waste in the two schools, as well as the timetable for its transfer to the disposal/burning site, have not been under control. Because the school has not demonstrated any sort of effective waste management, this requirement makes it more difficult for it to meet the target date for applying for SMP with the Adiwiyata predicate (in 2022). It is known from interviews and the findings of research questionnaires that the school is well-versed in the processes and effects of waste management (including plastic waste). Due to the limited infrastructure, expense, time, and governing laws, they have not been able to participate more. Through an educational approach to improving management conditions regarding the nature of the school as an educational area, and by empowering students as the main component of the school, an optimization of plastic waste management strategies at SMPN 1 and SMPN 5 Bangko Pusako was carried out in this study. Understanding is imparted by repeated verbal socialization, inclusion in instructional materials, use as an example in school life, as well as the creation of policies that have been unanimously agreed upon. Each part of the school is expected to reduce the amount of plastic trash produced, sort waste into its appropriate categories before disposal, reuse waste whenever possible to keep it out of the environment's rubbish heaps, and refrain from burning waste. Due to the majority of the debris being given to scavengers and stacked up, the results indicated a decrease in the volume of waste produced and the frequency of burning. The trash's contents may appear more appropriately for each type. Some plastic products have been replaced with other recyclable materials by students and instructors. This method of controlling plastic waste in the school setting is anticipated to serve as a good model for other schools.

Mycobacterium tuberculosis infection of a reverse total shoulder arthroplasty: a case report
Authors: MEERT C , POINOT N , HAUMONT E , TOLLET P
Published: June 2023

We describe the case of a 78-years-old male with dyspnea, inappetence and weight loss over a period of two weeks. The CT scan suggested disseminated tuberculosis and T5-T6 spondylodiscitis. During hospitalization, he developed a left shoulder pain where a reverse total shoulder arthroplasty was implanted 11 years ago. Open debridement and lavage with retention of the implant was performed first and intraveinous antibiotics were administered. 3 months after surgery the patient developed a painful sinus track at the incision site. Resection of the fistula tract, soft tissue debridement and removal of the implants were performed before restarting chemotherapy. As the incidence of reverse total shoulder arthroplasty continues to increase throughout the world, periprosthetic joint infection (PJI) will probably raise as well. Diagnosing and treatment of shoulder PJI with atypical germs remains a challenge and explantation seems to be the safer surgical option to avoid recurrent surgeries on patient with increasing comorbidities.

Published: June 2023

In this study, we aimed to compare the efficiency of Tönnis and the novel International Hip Dysplasia Institute (IHDI) in decision making and in presuming the outcomes in children who had undergone closed reduction and casting. 406 hips of 298 patients who had undergone closed reduction and spica casting were included in this retrospective study. All hips were classified according to Tönnis and IHDI systems. Bucholz-Ogden classification was used for avascular necrosis. The outcomes of patients for each classification system were compared, in terms of the presence of avascular necrosis, redislocations and secondary surgeries at the end of the follow-up period. 318 hips were evaluated as Tönnis grade 2 dysplasia. 24 had avascular necrosis, 9 had redislocations. 79 hips were evaluated as Tönnis grade 3 dysplasia. 18 had AVN, 7 had redislocations. 9 hips were evaluated as Tönnis grade 4 dysplasia 3 had AVN, 4 had redislocations. 203 patients were evaluated as IHDI grade 2 dysplasia. 7 had AVN, 7 had redislocations.185 patients were assessed as IHDI grade 3 dysplasia. 33 had AVN, 11 had redislocations. 18 patients were evaluated as IHDI grade 4 dysplasia. 5 had AVN, 6 had redislocations. Both Tönnis classification and IHDI classification systems are reliable and efficient systems for evaluating the severity and predicting the success of closed reduction and casting for the treatment of DDH. IHDI classification has certain benefits, such as being a practical classification and a better distribution within the groups.

Effect of Tarantula cubensis alcohol extract and Capecitabin combine in Colorectal Cancer rats
Authors: Canbar Rahmi , Ozdemir Ozgur , Bas Ahmet Levent
Published: June 2023

Colon cancer (CRC) is one of the most common types of cancer in the world. In this study, the effects of Tarantula cubensis alcoholic extract (TCAE) and the Capecitabine in CRC were investigated. Wistar albino rats were divided into eight groups with 12 animals in each group: untreated healthy and CRC groups, healthy and CRC groups treated with TCAE or Capecitabine, and healthy and CRC groups treated with both TCAE and Capecitabine. Azoxymethane was used in all CRC groups. TCAE and Capecitabine were administered to the relevant groups starting in the 15th week. All rats were euthanized after 18 weeks, and tissue samples were collected. The mRNA levels of Bcl–2, Bax, and Cas–3 in the harvested tissues were determined using real–time PCR and histopathologically abnormal crypt foci (ACF) scores were determined. It was found that TCAE modulated the decreased Bax/Bcl–2 expression rate in the CC group, but had the opposite effect in healthy animals, which was significantly reduced compared to the healthy groups (P<0.05). In addition, this rate was significantly lower in Capecitabine administered groups compared to other groups, and a paradoxical effect was observed (P<0.05). No significant change was observed in Cas–3 expression levels in all groups (P>0.05). Importantly, single and combined use of TCAE and Capecitabine in rats with CRC significantly reduced ACF scores (P<0.05). It can be stated that TCAE can specifically modulate the decreased Bax/Bcl–2 ratio in animals with cancer, and the therapeutic efficacy of Capecitabine is achieved at a dose of 40 mg·kg-1.

The differences in the academic achievements across semesters and areas of study of the children of new residents and residents studying in Taiwanese junior high schools have been ignored. The present study used the Keelung City Junior High School Students’ Learning Survey Database to explore the differences in the achievement in Chinese, English, mathematics, sociology, arts and literature, natural sciences, physical fitness, and comprehensive activities between the children of new residents and those of residents studying in junior high schools in different semesters. The data were analyzed at intervals of 1 year. 3 semesters of learning achievements of 1,586 students in 15 junior high schools were obtained from the database. Multivariate analysis of variance was used, and the following conclusions were drawn: The learning achievements of the children of new residents did not differ from those of residents in Chinese, English, mathematics, sociology, arts and literature, natural science, physical fitness, or comprehensive activities in the second semester of the first, second and third year. This contradicts the widely held belief that children of new residents have lower academic performance than children of residents. The findings of this study demonstrate that the learning achievements of the children of new residents and residents do not differ in the eight learning domains; schools, teachers, and students should disregard the aforementioned widely held belief. The study conclusions are discussed, and specific suggestions are provided.

Published: June 2023

The objective of this research is to compare pulses travelling through different photonic crystal fiber cores (DPCFC) using both finite element method (FEM) /split step Fourier method (SSFM). A unique DCPCF design with exceptionally high non-linearity has been introduced to achieve ultra-high pulse amplitude. Via a generalized non-linear equation, we evaluate the refractive index ratio and dispersion, for each type which is used, as well as output amplitude for different cores in different photonic crystal fiber core by utilizing the solution for the nonlinear Schrodinger equation (NLSE). Lastly, the findings are compared to different photonic crystal fiber design parameters. This paper provides a photonic crystal fiber design consisting of multiple liquid cores and theoretically solved non-linear equations. It was discovered in this design that the refractive index of propylene glycol (C3H8O2) is greater than ethylene glycol’s (C2H6O2), and that both are far greater than silica's refractive index (SiO2). Propylene (C3H8O2) has a lower dispersion than ethylene glycol (C2H6O2) and silica (SiO2). The output amplitudes of (C3H8O2) and (C2H6O2) were then shown to be substantially bigger than the output amplitudes of (SiO2) with respect to distance and time. This emphasizes the need for using certain liquids as cores in holey fibers, dependent upon their use.

Published: June 2023

Bacillus species are widely used for thermostable α-amylase production for various applications such as in the detergent and food industries. This research aimed to study the production of α-amylase by B. subtilis IMD34 in submerged fermentation conditions using Plackett-Burman (PB) design, along with the optimization of certain environmental factors for optimal growth of amylolytic bacteria. Plackett-Burman design was used to evaluate the effect of ten independent variables on α-amylase production. Maximum enzyme activity was recorded in a medium containing (g/l); starch (6.0), peptone (12.0), K2HPO4 (1.0), Na2HPO4 (2.0), NaCl (0.6), Na2SO4 (0.1), MgSO4.7H20 (1.0), FeCl3.6H2O (0.02), CaCl2.2H2O (0.02) and with an agitation speed (200 rpm). From the pareto chart it was observed that the most important independent variables for amylase production were starch, peptone, NaCl, Mg2SO4, CaCl2.2H2O and agitation. Optimization of environmental parameters to assess their effect on the growth of bacteria showed that optimal pH, incubation time and temperature were recorded at 6, 48h and 37˚C. Evaluating independent variables statistically using PB design revealed that some of the medium’s components had a positive impact on α-amylase production by B. subtilis IMD34.

The problem-based learning method is one of the methods that can be applied in EFL classes, especially for students' writing skills, so that it can create a pleasant learning atmosphere and make learning more active in classroom learning activities. The problem-based learning model is one of the learning models that can shape scientific behavior, social actors, and develop students' curiosity. Learners are initially faced with a problem, then followed by a student centered information search process. Seeing the importance of this method, this study aims to see the extent to which the PBL method can improve students' ability to write Narrative text. With Classroom Action Research design, this study was applied to 20 students of class X. In collecting data, tests were used to obtain an overview of student achievement, each of which was given in each cycle. The results of this study show that PBL can improve students' narrative text writing skills, this can be seen from the percentage of student results in each cycle. In addition to making the classroom atmosphere active and participatory, PBL also makes students think more critically in solving their problems. Students are required to be able to solve their problems both individually and in groups. Seeing the important role of this PBL method, the results of this study can be used as starting points or corrections for further research

Published: June 2023

This study assessed the impact of ICU admission delay on hospital mortality using electronic Cardiac Arrest Risk Triage (eCART). An observational cohort study was conducted in the Intensive care unit of Shifa International Hospital from April 2022- April 2023. A total of 400 patients admitted to medical and surgical wards were included in the study. The eCART score was used to estimate the extent of critical illness using demographic data from the records, vital signs, and laboratory data. A duration of 6 hours was considered a cut-off for the delay as it is usually a critical threshold in critically ill patients. The patients in both groups varied slightly with respect to age (69 vs. 71 years); all the other factors did not vary significantly. However, in-hospital mortality was higher in the delayed admission group (33.3%) than in the non-delayed group (25%). The length of ward stay did not vary between groups (1.3 vs. 1.4 days), but the total length of hospital stay was 2 days longer in the delayed transfer group. Based on the results, A delay in ICU admission is significantly related to high in-hospital mortality and longer hospital stays.
