Living with an Altered Body: A Qualitative Account of Body Image with Cancer Diagnosis and Its Treatment Among Women in Kolkata, West Bengal, India
Authors: Milky Mehboobun Nahar
Published: May 2024

Cancer diagnosis and its treatments influence the body image of patients in addition to bodily functioning. This qualitative study explores cancer patients' experiences with their bodies following cancer diagnosis and its treatment. For this study, in-depth, semi-structured interviews with five female cancer patients were conducted in Kolkata, West Bengal, India. The interviews were transcribed verbatim to include the insider’s perspective and then analysed using thematic analysis. The findings are divided into three major themes and eight sub-themes: the altered body (changed appearance, failing functional capabilities), emotional conflicts (feelings and emotions, loss of identity), and coping strategies (avoidance, clothing adjustments, social support, religious beliefs). Studies such as this one can help raise awareness among healthcare professionals about the heightened vulnerability of cancer patients, particularly women, to psychological distress arising from body image issues and beliefs. Additionally, insights from such research might help in the development of a framework for engaging in conversations about body image within oncology and palliative care teams, facilitating more effective patient care and support.

Na osnovu odabranih primera utvrđuju se elementi agresije, devijantnog ponašanja i kriminogenog delovanja maloletnih lica, ispoljeni u međusobnom fizičkom i verbalnom nasilju. Cilj je, takođe, da se potpunije osvetli sukob dobra i zla, njegova geneza i razvoj, kao i posledice po etičko i psihološko sazrevanje malih junaka, koji iskazuju različite vidove ljubavi, empatije i (ne)razumevanja.
SCAREDY SQUIRREL BY MELANIE WATT – INTERACTION OF THE VERBAL AND THE VISUAL
Authors:   Belgrade City Library, Serbia, PETROVIĆ Biljana T.
Published: May 2024

The paper deals with the picture book Scaredy Squirrel illustrated and written by the Canadian author Melanie Watt. First, it is about the contemporary production of picture books about feelings, and then it is considered what is the place of the picture book Scaredy Squirrel among them. The picture book is analyzed as dual, visual, and verbal piece of art whose meaning emerges from the dialogue between image and text. The role of paratext, metatextual playing and the fragmentation of the narrative dominated by linguistic and pictorial enumerations and interruptions of linear storytelling with non-literary genres (tables, plans, lists) are pointed out. The emphasis is on interactivity and communicativeness and addressing a dual readership, children and adults. Children are encouraged in an unobtrusive, playful, and humorous way, while the understanding of adults is also offered with meanings related to criticism and parody of modern media and the society of fear.

This paper investigates the generalized linear multi-terms delay fractional diﬀerential equation of variable order with periodic and anti-periodic conditions. In this work, a novel shifted Jacobi operational matrix technique is applied to solve a class of these equations, so that the original problem becomes a system of algebraic equations that can be solved by numerical methods. The proposed technique is successfully applied to the aforementioned problem. Suﬃcient and complete numerical tests are presented to demonstrate the accuracy, generality, eﬃciency of presented technique and the ﬂexibility of this scheme. The numerical results of this method are compared with other existing methods such as fractional backward diﬀerential formulas (FBDF). Comparing the outcomes of these schemes, as well as comparing the current technique (NSJOM) with the exact solution, demonstrates the eﬃciency and validity of this method. It should be noted that the implementation of current method is considered very easy and general for many numerical techniques. Furthermore, the error and its bound are estimated.

This paper deals with the existence and uniqueness of solution for a new class of Ψ-Caputo fractional differential Langevin equation. The suggested study is based on some basic definitions of topological degree theory and fractional calculus. We established the existence result by using the topological degree method for condensing maps, and by means of Banach’s fixed point theorem we obtained the uniqueness result. As application, we give an illustrative example to demonstrate our theoretical result.

Published: May 2024

In the article, we study the approximate numerical solution to the boundary value problem in ordinary diﬀerential equations. In the present article, a third-order two-point boundary value problem is considered for discussion. We developed a second order accurate ﬁnite diﬀerence method for the approximate numerical solution of the considered problem. We took a special boundary condition; we did not ﬁnd this boundary condition in the literature. We have discussed the standard convergence analysis of the proposed method. Numerical experiments on linear, nonlinear, and obstacle problems approve the order of accuracy and eﬃciency of the method.

Authors:   Belarussian State University, Minsk, Belarus, Antonevich A. B. , Kuzmina E. V. ,   Brest Thechnical University, Brest, Belarus
Published: May 2024

The article deals with the problem of existence of generalized solutions to simplest linear differential equation with a singular coefficient q. The generalized solution was introduced by choice one of the distribution Q corresponding q, and choice an approximation of Q by a family of common functions. The generalized solution is defined as the limit of the solutions of the approximating equations. It was demonstrated by model example that the existence of such generalized solutions depends essentially on the method of approximation.

Authors: Sumeru Indrawati , Sutjipto Suradjin , Supardjo William , Sucipto Sherrica Augustin
Published: May 2024

Due to increasing awareness of human safety, Indonesia has mandated that all operational buildings obtain a Certificate of Occupancy. Consequently, existing structures must undergo a structural assessment before being granted this certificate. Evaluating older buildings poses significant challenges, especially when comprehensive records are lacking, and budgets do not allow for Non-Destructive Testing (NDT). This study presents the structural evaluation findings of a three-story steel building in Jakarta. Using visual inspections, field measurements, and limited available data, an analytical model representing the building's actual condition was developed. The evaluation followed three procedures: Tier 1 and Tier 2 evaluations of ASCE 41-17 and proportional seismic forces. These procedures aimed to gauge the structural integrity and identify areas vulnerable to failure during a severe earthquake. The assessment focused on the ductility of the seismic force-resisting system components and the strength of beam-column joint connections against specified acceptance criteria. The findings highlight critical insights into the building’s structural performance, informing decisions on necessary measures such as structural reinforcement, occupancy restrictions, or demolition. This study underscores the importance of thorough structural assessments in ensuring the safety and resilience of older buildings in earthquake-prone regions.

Gender ideology in the context of attitudes and views concerning violence against women (VAW) is a crucial global issue, particularly in Bangladesh. This study explores gender ideology toward violence against women in rural Bangladesh. This study followed a mixed-methods research technique, conducting two focus group discussions (FGDs) and interviewing 400 rural people (200 men and 200 women, aged 18 to 50) from eight cluster villages in Paba Upazila of Rajshahi District, Bangladesh. The findings indicate that people were traditional in their attitudes toward women’s empowerment and violence, victim-blaming, men’s power over women, and acceptance of male dominance but liberal in their views on the relationship between hijab/veil and violence against women. This study argues that patriarchal adherence is represented among people’s gender ideology in rural Bangladesh. The findings of this study imply that improving awareness about gender and violence could help to promote liberal thinking among individuals in rural Bangladesh, hence preventing widespread attitudes toward violence against women.

Background and aim: As the spleen plays a significant role in immunity, the aim was to investigate the associations of different body composition markers derived from various sources with spleen volume in a general population sample.
Materials and methods: Cross-sectional data of 1095 individuals (570 women; 52%) aged between 30 and 90 years were collected in the Study of Health in Pomerania (SHIP-START-2). We measured spleen volume by magnetic resonance imaging (MRI).
Body composition markers were derived from classic anthropometry, bioelectrical impedance analysis, including absolute fat mass (FM) and fat-free mass (FFM), as well as from MRI, including visceral adipose tissue (VAT), subcutaneous adipose tissue (SAT), and liver fat content. Sex-stratified-adjusted linear regression models were used to analyze the associations of body composition markers with spleen volumes.
Results: We observed positive associations of body mass index, body weight, waist circumference, hip circumference, waist-to-height ratio, absolute FM, absolute FFM, and VAT and SAT with spleen volume in men and women. An 8.12 kg higher absolute FFM was associated with a 38.4 mL (95% confidence interval [CI]: 26.7–50.1) higher spleen volume in men and a 5.21 kg higher absolute FFM with a 42.6 mL (95% CI: 26.2–59.0) higher spleen volume in women.
Conclusion: Our findings indicate that obesity-related body composition markers and FFM are associated with a higher spleen volume. Particularly, higher absolute FFM showed a strong association with a larger spleen volume in both men and women. Further studies are warranted to understand the clinical significance of body composition markers on large spleen volume.
Performance Analysis of Extended and Sigma-Point Kalman Filter for State-of-Charge Estimation for Battery Management System
Authors: Himanshu Maithani  , Sandeep K. Goel  , Anurag K. Swami
Published: May 2024

Lithium-ion batteries are state-of-the-art energy storage technology. Instead of having remarkable features, a highly accurate, reliable, and cost-effective battery monitoring technology should continuously monitor the battery cell parameters and ensure the parameters are within the safe operating area recommended by the manufacturer. Precise estimation of SOC is always needed to ensure the safety and longevity of each lithium-ion cell in a battery pack affected by frequent charge and discharge processes. Algorithms based on Kalman filter recursive state estimation are robust to initial SOC uncertainties and sensor noise. Since the internal electrochemical kinetics of the Li-Ion cells are highly complex and non-linear, the Kalman filer non-linear variants such as EKF and SPKF perform exceptionally well in the presence of uncertainties in the initial SOC estimates and sensor measurements. This paper evaluates the robustness of EKF and CDKF regarding state of charge (SOC) estimation accuracy against unknown initial SOC and random sensor noise. The algorithms are implemented in the GNU Octave environment. The experiment results show that SPKF slightly outperforms EKF in terms of rms values. Both EKF and SPKF demonstrate strong robustness against current noise

A Doença de Alzheimer (DA) é caracterizada por uma deterioração da cognição, da função e do comportamento humano, sendo a causa mais habitual de demência. Nesse sentido, a prática de exercícios físicos e algumas dietas específicas, tais quais a dieta cetogênica e a dieta do mediterrâneo, começam a despontar em alguns estudos como fatores preventivos da Doença de Alzheimer, acarretando uma demanda de estudos mais aprofundados e uniformizados sobre estes fatores preventivos. Desse modo, o presente trabalho objetivou compreender a relação entre as dietas cetogênica e do mediterrânea e a prática de exercícios físicos regulares como fatores para a prevenção da Doença de Alzheimer. Trata-se de uma revisão bibliográfica acerca desses fatores na prevenção da Doença de Alzheimer. Para tanto, após devida aplicação de critérios de inclusão e exclusão, 20 (vinte) artigos foram selecionados para a redação deste trabalho. Dentre estes, foram observados que os hábitos alimentares apresentam atribuição primordial na prevenção e também retardo da evolução da patologia, sobretudo a dieta cetogênica e a mediterrânea, as quais possuem como base uma rotina dietética diversificada, destacando-se a alimentação como um fator modulador, ou seja, modificador do curso da doença. No mais, conforme se extraiu da referida literatura, existem várias vias relacionadas à prevenção da Doença de Alzheimer junto à prática de exercícios físicos. Não podemos deixar de notar, contudo, que algumas dessas vias são divergentes na literatura científica. Ainda assim, a maior parte das pesquisas tende a uma associação positiva. Assim, constata-se que a prática de exercícios físicos associada a outras medidas é eficiente para a prevenção da Doença de Alzheimer.

Published: May 2024

Abstract. Water cycle process will deeply affect water vapour isotope composition, in addition to the evaporation and condensation processes, the exchange process is also a crucial process that influences isotopic variations. To explore the mechanism of isotope exchange under isothermal saturation conditions, we developed an isotope exchange calculation equation for water vapour (IECEWV) based on the conservation of exchange quantity and conducted indoor trials with 100 control groups to validate the IECEWV. The experimental findings demonstrated that the isotopic values of water vapour exhibited enrichment, depletion, and stabilisation during the exchange process when the droplet size first increased and then stabilised, because of the interaction between the exchange state, isotopic gradients, and specific surface area of the droplets according to IECEWV. The variation trend of IECEWV calculated isotopes in water vapour was consistent with experimental value, with average maximum relative errors of 1.66 % for δ2H and 3.19 % for δ18O, and IECEWV analysis further indicates isotopes exchange can lead to the hydrogen and oxygen isotope line of water vapour deviate from the origin. Furthermore, the linear relationship between hydrogen and oxygen isotopes in water vapour after exchanged can be characterised by linear clusters with the same slope, the d-excess of water vapour remains essentially constant. Future studies may combine the IECEWV with the Rayleigh fractionation model to explore the coordinated changes in precipitation and atmospheric water vapour isotopes.
Shipborne observations of black carbon aerosols in the western Arctic Ocean during summer and autumn 2016–2020: impact of boreal fires

Published: May 2024

Abstract. Black carbon (BC) aerosol is considered one of the most important contributors to rapid climate warming as well as snow and sea ice melting in the Arctic, yet the observations of BC aerosols in the Arctic Ocean have been limited due to infrastructural and logistical difficulties. We observed BC mass concentrations (mBC) using light absorption methods on board the icebreaker R/V Araon in the Arctic Ocean (< 80° N and 166° E to 156° W) as well as the North Pacific Ocean in summer and early autumn of 2016–2020. The levels, interannual variations, and pollution episodes of mBC in the Arctic were examined, and the emission sources responsible for the high-BC episodes were analyzed with global chemistry-transport-model simulations. The average mBC in the surface air over the Arctic Ocean (72–80° N) observed by the 2019 cruise exceeded 70 ng m−3, which was substantially higher than that observed by cruises in other years (approximately 10 ng m−3). The much higher mBC observed in 2019 was perhaps due to more frequent wildfires occurring in the Arctic region than in other years. The model suggested that biomass burning contributed most to the observed BC by mass in the western Arctic Ocean and the marginal seas. For these 5 years, we identified 10 high-BC episodes north of 65° N, including one in 2018 that was associated with co-enhancements of CO and CH4 but not CO2 and O3. The model analysis indicated that certain episodes were attributed to BC-containing air masses transported from boreal fire regions to the Arctic Ocean, with some transport occurring near the surface and others in the mid-troposphere. This study provides crucial datasets on BC mass concentrations and the mixing ratios of O3, CH4, CO, and CO2 in the western Arctic Ocean regions, and it highlights the significant impact of boreal fires on the observed Arctic BC during the summer and early autumn months.
Direct observational evidence from space of the effect of CO2 increase on longwave spectral radiances: the unique role of high-spectral-resolution measurements
Authors: Teixeira João , Wilson R. Chris , Thrastarson Heidar Th.
Published: May 2024

Abstract. We present a direct measurement of the impact of increased atmospheric CO2 on the spectra of the Earth's longwave radiation obtained from space. The goal of this study is to experimentally confirm that the direct effects of CO2 increase on the Earth's outgoing longwave spectra follow theoretical estimates, by developing a methodology that allows for a direct and more precise comparison between theory and observations. In this methodology, a search is performed to find selected ensembles of observed atmospheric vertical profiles of temperature and water vapor that are as close as possible to each other in terms of their values. By analyzing the spectral radiances measured from space by the Atmospheric Infrared Sounder (AIRS), corresponding to the selected ensembles of profiles, the effects of increased CO2 on the spectra can be isolated from the temperature and water vapor effects. The results illustrate the impact of the increase in CO2 on the longwave spectra and compare well with theoretical estimates. As far as the authors are aware, this is the first time that the spectral signature of the increase in CO2 (isolated from temperature and water vapor changes) has been directly observed from space.
A Gamified Platform to Encourage Sustainable Behaviours
Authors: Soares Manuel , Romão Teresa , Rodrigues Armanda
Published: May 2024

Abstract. The production, use, and disposal of goods and services require the use of natural resources, resulting in waste and environmental pollution. A growing number of people are embracing more sustainable lifestyles in alignment with the 3Rs (Reducing, Reusing, and Recycling) to counter these effects, but many remain uninformed of their options, or lack the motivation to adopt these practices. The work described in this paper addresses these issues through the development of the Sustainable App, a mobile application incorporating techniques of persuasion and gamification which offers its users eco-friendly alternatives to several types of daily activities, made available via an interactive map. The app employs diverse strategies to improve engagement, including a pet-nurturing game-like feature that responds to user actions related to sustainable transport choices, sustainable retail, and recycling. Additionally, the complete platform associated with the app also delivers Just-In-Time (JIT) messages concerning nearby sustainable choices based on location and time. Upon evaluation of the platform, positive user experience and overall good feedback were noted. Experts also weighed in on the application’s evaluation, offering valuable insights to refine future iterations.

Abstract. Both the degree of urbanisation and climate change are continuing to accelerate. As a result, heat islands in cities are an increasing problem. In this article, we analyse a dataset of land surface temperatures in Berlin. The heat information is not mapped on administrative or census units, but summarised into so-called urban structure type units. These are not only meaningful in terms of their inherent link to urban heat but also represent a geography that is relevant for planning purposes. Our analysis complements existing studies in Berlin by applying two novel visual spatial analysis methods: the Moran drop plot and the Moran seismogram. These allow structures to be visually explored that are not found in traditional Moran scatterplots. In this way, we can visualise that low-temperature areas tend to be more homogeneously clustered than their high-temperature counterparts. In turn, the latter can be identified in the plots as clearly smaller in geographic scale and thus as more heterogeneous in the neighbourhoods formed. Finally, we draw conclusions including possible policy-relevant considerations.
Robustness of the long short-term memory network in rainfall-runoff prediction improved by the water balance constraint

Abstract. While the water balance constraint is fundamental to catchment hydrological models, there is yet no consensus on its role in the long short-term memory (LSTM) network. This paper is concentrated on the part that this constraint plays in the robustness of the LSTM network for rainfall-runoff prediction. Specifically, numerical experiments are devised to examine the robustness of the LSTM and its architecturally mass-conserving variant (MC-LSTM); and the Explainable Artificial Intelligence (XAI) is employed to interrogate how this constraint affects the robustness of the LSTM in learning rainfall-runoff relationships. Based on the Catchment Attributes and Meteorology for Large-sample Studies (CAMELS) dataset, the LSTM, MC-LSTM and EXP-HYDRO models are trained under various amounts of training data and different seeds of parameter initialization over 531 catchments, leading to 95,580 (3×6×10×531) tests. Through large-sample tests, the results show that incorporating the water balance constraint into the LSTM improves the robustness, while the improvement tends to decrease as the amount of training data increases. Under 9 years’ training data, this constraint significantly enhances the robustness against data sparsity in 37 % (196 in 531) of the catchments and improves the robustness against parameter initialization in 73 % (386 in 531) of the catchments. In addition, it improves the robustness in learning rainfall-runoff relationships by increasing the median contribution of precipitation from 45.8 % to 47.3 %. These results point to the compensation effects between training data and process knowledge on the LSTM’s performance. Overall, the in-depth investigations facilitate insights into the use of the LSTM for rainfall-runoff prediction.

Penelitian ini bertujuan untuk menganalisis strategi pemasaran peternak ikan jaring terapung di KP Leuwinutug. Metode yang digunakan dalam penelitian ini adalah deskriptif kualitatif dengan menggunakan teknik wawancara dan observasi langsung pada peternak ikan jaring terapung yang berada di KP Leuwinutug. Hasil penelitian menunjukkan bahwa strategi pemasaran yang digunakan oleh peternak ikan jaring terapung di KP Leuwinutug terdiri dari tiga tahap, yaitu produksi ikan, distribusi ikan, dan penjualan ikan. Di tahap produksi, peternak ikan jaring terapung menggunakan teknologi jaring terapung dan bahan pakan yang berkualitas untuk memproduksi ikan yang sehat. Di tahap distribusi, peternak ikan jaring terapung menjual ikan langsung ke pengepul yang berada di KP Leuwinutug. Di tahap penjualan, pengepul kemudian menjual ikan ke pedagang kecil atau pengecer yang selanjutnya dijual ke konsumen akhir. Meskipun strategi pemasaran yang digunakan oleh peternak ikan jaring terapung di KP Leuwinutug telah cukup baik, namun masih terdapat beberapa kendala seperti keterbatasan modal dan kurangnya promosi yang efektif. Oleh karena itu, diperlukan upaya dari pemerintah dan lembaga terkait untuk membantu meningkatkan modal dan promosi produk peternak ikan jaring terapung di KP Leuwinutug.
