Published: September 2024

Digitalization is to the process of changing information into a digital format. It involves the adoption and use of digital technologies to transform business processes, activities, and models. Here are key aspects of digitalisation. Converting analog information, such as text, images, and sounds, into digital formats that can be processed and stored electronically. Utilizing digital technologies such as computers, smartphones, software applications, and networks to automate tasks, improve efficiency, and enable new capabilities. Applying digital technologies to innovate business models, streamline operations, enhance customer experiences, and create new revenue stream. Facilitating instant communication and connectivity through digital channels such as email, messaging apps, social media, and video conferencing. Managing and analyzing large volumes of data (big data) to derive insights, make informed decisions, and personalize services. Automating repetitive tasks and processes through digital tools and technologies to increase productivity and reduce costs. Implementing measures to protect digital assets, data, and privacy from cyber threats and unauthorized access. Influencing how individuals interact, communicate, work, learn, and consume information in a digital-first world. Digitalisation is not just about adopting technology but also about leveraging it strategically to drive innovation, competitiveness, and growth across various sectors of society and the economy. It is a fundamental aspect of the broader digital transformation sweeping across industries globally. The purpose of this paper is to understand digitalisation and its impact on rural India.

Published: September 2024

Background: The shift to e-learning, particularly during the COVID-19 pandemic, has transformed higher education. However, there is limited understanding of how e-learning affects the emotional well-being of postgraduate students. This study addresses this gap by examining the impact of different e-learning modalities on interpersonal relationships and emotional well-being in postgraduate students in Nairobi County, Kenya. Objective: The study investigates how e-learning modes influence emotional well-being, focusing on the role of interpersonal relationships and the moderating effect of perceived social support. Methods: A mixed-methods approach was employed using an embedded-correlational design. Quantitative data were collected through the PERMA Adult Profiler, while qualitative insights were gathered from open-ended interviews. The sample included 323 postgraduate students from nine universities in Nairobi County, with an additional eight participants for qualitative analysis. Results: Findings revealed high levels of interpersonal support and satisfaction with personal relationships. However, no e-learning mode significantly predicted interpersonal relationships (p > 0.05). Blended Learning, which combines online and in-person sessions, achieved the highest mean score, followed by Pure Online Teaching. These findings suggest that while e-learning mode does not critically influence interpersonal relationships, both Blended Learning and Pure Online Teaching foster strong social connections. Implications: The study underscores the importance of institutional and supervisory support in enhancing the e-learning experience. Future research should explore diverse contexts and long-term effects to further understand e-learning’s impact on interpersonal relationships and academic success.

Published: September 2024

Strobilanthes crispus, a medicinal herb, is recognised for its abundant phytochemicals, notably in its leaves, contributing to its high antioxidant activity. However, the crucial step of drying, aimed at extending shelf life, can impact the stability of these bioactive compounds. This study evaluates the impact of different drying methods, which include oven, microwave, freeze drying, and air drying, on the colour, phenolic and flavonoid content, and antioxidant activities of S. crispus leaves. The colour analysis of the fresh and dried leaves was assessed using the chromameter. Total phenolic content (TPC) and total flavonoid content (TFC) were determined using Folin-Ciocalteu’s and aluminium chloride colourimetric assays, respectively. Antioxidant capacities were analysed via ferric-reducing antioxidant power (FRAP) and a 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging assay. The results showed that microwave-dried S. crispus leaves exhibited minimal alterations in colour attributes L*, a*, and b*, closely resembling the fresh leaves (p > 0.05). Microwave drying significantly preserved TPC (145.42 ± 1.61 mg GAE/g), TFC (117.27 ± 5.10 mg QE/g), FRAP activity (258.92 ± 0.15 µg TE/g extract), and displayed the most potent DPPH scavenging half-maximal inhibitory concentration (7.58 ± 0.48 µg/ml) compared to other methods (p < 0.05). Notably, the DPPH scavenging potency surpassed that of the synthetic antioxidant butylated hydroxytoluene. In conclusion, microwave drying appeared to be an efficient method for preserving the colour and antioxidant properties of S. crispus leaves. It highlights its potential as a favourable drying technique for conserving bioactive compounds in medicinal plant materials, offering promising applications in the nutraceutical and pharmaceutical fields.

Authors: Kedar Shridhar , Kolhalkar Nilesh , Mishra Prerna
Published: September 2024

In order to address the problem of the reliability of current environmental pollution assessment methods, a comprehensive assessment method of environmental pollution in tourist scenic spots based on improved principle component analysis was proposed. First air, water, and soil pollution for data tourist attractions in the top 5 metropolitan cities of India are collected. Then, the original pollution data is cleaned, the data clustering method is used to classify the pollution data, and the comprehensive evaluation index system of environmental pollution in tourist attractions is established. Finally, the comprehensive evaluation method is implemented to calculate the evaluation values of various indicators, and the comprehensive assessment results of pollution at tourist attractions are obtained. The experimental results show that the correlation of the evaluation index is always controlled above 0.90, the convergence rate of the method is fast, the optimal solution can be approached within 150 iterations, and the application effect is good.

Acquirer ESG, Home Country Policy Enforcement, Country Distance, and Cross-Border Mergers and Acquisitions: Evidence from Chinese Firms
Authors: Guo Jianquan , Kou Jiao
Published: September 2024

This paper examines the impact of ESG (Environmental, Social, and Governance) on cross-border M&A activities and outcomes from the perspective of emerging economy firms. Using cross-border M&A events of Chinese acquirers between 2009 and 2021 as a sample, we employ logistic regression and multiple linear regression for analysis and conduct robustness tests. The study finds that: (1) Acquirers with lower ESG ratings are more likely to choose other developing countries for M&A, and the home country’s policy enforcement significantly positively moderates this relationship; (2) Lower ESG ratings of acquirers have a significant negative impact on their M&A performance, while the country distance between China and the host country does not have a significant moderating effect on this relationship. These results suggest that under strong home country policy enforcement, emerging economy firms are pressured by their home country’s ESG ratings to choose host countries with lower ESG requirements for M&A. However, this approach is like “drinking poison to quench thirst”; while selecting an “ESG haven” can temporarily reduce ESG rating pressure, low ESG ratings ultimately result in lower M&A performance.

Authors: Suarez-Silva David , Katime Zúñiga Abraham , Calderon Willem , Faccini-Martínez Álvaro A. , Hernandez-Paez David A.
Published: September 2024

Typhoid fever (enteric fever), caused by Salmonella enterica subsp. enterica serovar Typhi (S. Typhi), is a public health problem especially in South Asia and sub-Saharan African countries, while incidence remains low in most other parts of the world, where the disease is primary related to recent travel to endemic countries or contact with chronic carriers. The diagnosis of typhoid fever is challenging in endemic countries, often also low- and middle- income countries (LMIC), due to the poor sensitivity/specificity of available serologic tests and lack of adequate infrastructure for blood cultures. We report the case of an 18-year-old male patient with a 21-day history of right-sided abdominal pain, malaise, headache, intermittent fever and watery diarrhea. Contrast-enhanced abdominal computed tomography (CT) exhibits thickening of the terminal ileum, cecum and ascending colon with mesenteric lymphadenopathy. Laboratory findings indicate elevated transaminases, positive blood culture to S. Typhi and a positive Widal test to S. Paratyphi A, B and S. Typhi H (flagellar) antigens. A diagnosis of complicated typhoid fever was made. Following a 13-day regimen of ceftriaxone, all symptoms resolved. Few reports have been made about CT manifestations in patients with typhoid fever. While CT can aid in diagnosis, it is particularly important for identifying complications of typhoid fever such as perforation, bleeding and abscess formation.
Bullous Herpes Zoster in a Lupus Nephritis Patient Treated with Rituximab: A Case Report
Authors: Esquivel, MD Amanda Christine F. , Gonzales, MD Juan Raphael M. , Zamora, MD Geraldine T. , Tioleco-Ver, MD Giselle Marie S.
Published: September 2024

Herpes zoster is a clinical syndrome associated with reactivation of varicella zoster virus (VZV), often occurring years after VZV infection, and characterized typically by painful grouped vesicles in a dermatomal distribution. Bullous herpes zoster, an atypical presentation of herpes zoster, is a relatively rare phenomenon; to the authors’ knowledge, there have only been eight reports in worldwide literature. We present a case of a 59-year-old female with lupus nephritis who presented with multiple grouped vesicles evolving into large tender bullae filled with serosanguinous fluid on the lateral aspect of the right leg, and dorsal and medial aspects of the right foot, four days after the first dose of 1g of rituximab therapy. The diagnosis of bullous herpes zoster along L4-L5 dermatomes was made based on the clinical presentation and the presence of multinucleated giant cells on Tzanck smear. The giant bullae were drained and dressed, and the patient was treated with valacyclovir at the renally adjusted dose of 1g once a day for seven days and pregabalin 150 mg once daily. After seven days of antiviral treatment, there were no new bullae or vesicles, and the pain improved. Recognizing this atypical presentation of a common disease, especially in patients with an immunocompromised state, highlights the importance of prompt recognition and treatment.
A Peculiar Pattern: Nodular Secondary Syphilis with Granulomatous Dermatitis
Authors: Villaverde, MD Marian Rosel D. , Villena, MD Juan Paolo David S. , Yap Silva, MD Claudine
Published: September 2024

Nodular syphilis with a granulomatous inflammatory histopathologic pattern is an uncommon cutaneous presentation of secondary syphilis which could pose a diagnostic challenge for clinicians and pathologists alike.
A 33-year-old male diagnosed with HIV presented with a 5-week history of asymptomatic generalized erythematous papules and nodules with overlying scales, with involvement of the palms and soles. Histopathologic examination of a nodule from the forearm revealed non-caseating granulomas in a background of a mixed cell inflammatory infiltrate composed of lymphocytes, epithelioid and foamy histiocytes, plasma cells, neutrophils, and multinucleated giant cells. Warthin-Starry Stain revealed spirochetal organisms, while Fite-Faraco and Periodic Acid-Schiff stains were negative for acid-fast bacilli and fungal elements, respectively. Rapid plasma reagin (RPR) was reactive (1:256). Patient was given a single dose of benzathine penicillin G 2.4 million units intramuscularly, with noted complete resolution of skin lesions as well as an 8-fold decrease in RPR titers.
Nodular lesions are an uncommon cutaneous manifestation of secondary syphilis, and the associated histopathologic finding of granulomatous inflammatory pattern is also unusual, posing a diagnostic challenge. With the increasing prevalence of syphilis, especially among HIV patients, dermatologists, dermatopathologists, internists, and infectious disease specialists should be aware of such presentations of syphilis.
Zróżnicowanie warunków bioklimatycznych między centrum Lublina i obszarem podmiejskim w półroczu letnim
Authors: Bartoszek Krzysztof , Kaszewski Bogusław , Siwek Krzysztof
Published: September 2024

The aim of this study is to assess the differences in the occurrence of harsh bioclimatic conditions between the center of Lublin and non-urban areas in the warm half of the year (April-September) and to determine the rate of changes in these conditions in both analysed meteorological stations in the years 1973–2022. To assess the bioclimatic conditions, the biometeorological index Humidex was used. In the first part of the study period, the number of days with unfavourable bioclimatic conditions prevailed in the city center, while in the last two decades the differences have decreased, mainly as a result of the development of concentrated buildings in the suburban area. In both measurement points, there was a significant increase in the number of days with strong thermal and hygric loads on the human body. The study also presents the reasons for the occurrence of selected cases with significant differences in the index values in the Lublin region, as well as the synoptic conditions on the day with the highest recorded Humidex value during the study period.
A Study on Employees Perception towards NPS & EPF
Authors: Mr. Naresh Kumar S  , Dr. Shailaja M. L
Published: September 2024

The study "A Study on Employees' Perception towards NPS & EPF" investigates the views of employees regarding two of India's most prominent pension schemes: the National Pension System (NPS) and Employees' Provident Fund (EPF). The research aims to understand employees' preferences and satisfaction levels with these schemes based on factors such as returns, risk, ease of access, transparency, and tax benefits.NPS, being a market-linked pension scheme, offers higher flexibility and potential for better returns but also carries a higher risk. It is typically favored by employees who seek control over their investments and are comfortable with market fluctuations. In contrast, EPF is a government-backed, more stable scheme, offering lower risk but fixed returns. It is preferred by risk-averse employees who prioritize security over potentially higher gains.
Through primary data collected from employees across different sectors, the study highlights key insights into how employees' perceptions differ based on their employment type, income levels, and financial goals. Understanding these perceptions is crucial for policymakers and employers to address gaps in awareness and satisfaction, thereby encouraging more informed decisions for retirement planning and improving participation in both pension schemes. The study contributes to a broader understanding of retirement planning preferences in India

Authors: Collantes G. Rubén D. , Samaniego Jahzeel , Jerkovic Maricsa , Santos-Murgas Alonso
Published: September 2024

El género Leptoglossus (Hemiptera: Coreidae), tiene amplia distribución en el continente americano y comprende especies de importancia agrícola como plagas en cultivos estratégicos para la seguridad alimentaria y nutricional (SAN). En Cerro Punta, zona productora de diversas hortalizas y frutas, se ha observado en cultivos de café y maíz la presencia de un chinche Leptoglossus de coloración marrón rojiza con una banda transversal de color claro, recta y completa sobre los hemiélitros, por lo que el objetivo del estudio fue identificar dicha especie de insecto. Para ello, entre noviembre de 2021 y abril de 2024, se registraron observaciones en el área de estudio de chinches Coreidae, realizándose además colectas de especímenes inmaduros y adultos para su identificación en el laboratorio, consultando literatura especializada. Los resultados reflejaron que la especie insectil corresponde a Leptoglossus phyllopus (L., 1767), dado que los caracteres morfológicos externos observados en ninfas y adultos, como el hábito, la coloración y la forma de la tibia posterior, concuerdan con lo descrito para dicha especie. El insecto es de amplia distribución, desde el sur de los Estados Unidos de América hasta Brasil, con registros previos en Panamá en las provincias de Panamá Oeste, Colón y Chiriquí. En cuanto a los cultivos asociados a este insecto, se le encontró en maíz y café, aunque al considerar su condición polífaga, es posible que pueda afectar otros rubros. En conclusión, la especie de chinche encontrada en Cerro Punta corresponde a Leptoglossus phyllopus, asociado a dos cultivos estratégicos para la SAN.

Authors: Martínez Pérez Natalia , Cuenca Orellana Nerea , Dueñas Mohedas Sonia
Published: September 2024

La animación se ha hecho eco de la importancia que la salud mental ha adquirido recientemente en la sociedad. Identificar las emociones propias e interpretarlas para saber cómo desarrollar habilidades, tomar decisiones y, en definitiva, conocerse individualmente, suponen uno de los principales retos a los que se enfrenta el sujeto contemporáneo. Este artículo explora, desde una perspectiva de género, el tratamiento de la inteligencia emocional en la ficción surcoreana a través de la serie Yumi’s Cells (2021-2022), que combina imagen real y animación. Mediante un análisis textual, se confirma que la representación de los personajes animados sirve como una herramienta pedagógica para que la audiencia aprenda a detectar las emociones cotidianas, particularmente en un contexto como el de la sociedad surcoreana que adolece de determinados recursos psicológicos, pues la extroversión de las emociones es considerada un tabú social.
Permanentemente temporários: reflexões sobre a contratação de professores(as) em Minas Gerais
Authors: Santos Braga Daniel , Santos Araújo Eduardo , De Fátima Oliveira Rosimar
Published: September 2024

Este artigo objetiva discutir a contratação temporária de professores na Rede Estadual de Educação de Minas Gerais, Brasil (2011-2020). A hipótese é que a manutenção de contingente expressivo de docentes com vínculos precários de trabalho consiste em estratégia para redução de despesas com folha de pagamento de pessoal. A fundamentação teórica assume que a seleção de professores por concurso público e sua estabilidade funcional são parte do processo de profissionalização docente e incorporação à burocracia do Estado. Foram coletadas informações educacionais e orçamentárias em fontes oficiais, submetidas a tratamento estatístico descritivo. Como resultados, revelou-se que na maior parte da década, o percentual de funções docentes temporárias foi significativamente superior ao de professores efetivos. Apesar disso, o gasto com pagamento de efetivos foi maior que o de temporários em todos os anos da série, o mesmo ocorrendo com sua remuneração. Identificou-se que a ausência de carreira e consequente impossibilidade de promoções e progressões, com ganhos pecuniários incorporáveis, faz com que essa opção de contratação tenha menos impactos orçamentários no tempo, a despeito de seus possíveis prejuízos para a vida profissional desses trabalhadores, e de suas repercussões pedagógicas negativas.
Conjugate Riedel shears in a volcanic caldera: the case of the Laguna del Maule Volcanic Complex, Central Chile
Authors: Pastor Castilla Alvar , Contreras Osses Macarena Constanza , Corral Calleja Isaac
Published: September 2024

The Andean intra-arc is characterized by large-scale continuous lineaments, often the direct surface expression of tectonic structures. In this study, we analyze the main lineaments around the Laguna del Maule Volcanic Complex, Central Chile (~36° S), to shed light on the main tectonic processes. We show that the lineament directions are consistent with structures based on a theoretical Riedel model and suggest the occurrence of two conjugate Riedel shears crossing Laguna del Maule. This structural arrangement can accommodate deformation related to either a transtensional regime, having a WNW-oriented master fault (Laguna Fea Fault), or a transpressional regime, characterized by NNE-oriented master faults (e.g., Melado Fault). In this context, the NE-striking Troncoso Fault would be a long-lived dextral fault compatible with both regimes. According to the Riedel model, ENE-oriented lineaments are predicted to be tensional structures, whilst NW-oriented structures (e.g., Los Cóndores Fault) would correspond to P-type structures accommodating compressional deformation. This tectonic architecture, characterized by the most intense deformation just at the intersection between shears, has likely promoted magma accumulation and would explain the compositional variability at Laguna del Maule. This study therefore demonstrates the usefulness of oriented lineament maps in interpreting regional tectonics for volcanically active areas.
Detección de roca intrusiva alterada mediante tomografía de resistividad eléctrica: El caso del área de San Luis, zona central de Panamá

Published: September 2024

This work investigates the potentiality of the 2D electrical resistivity tomography method to delineate an altered intrusive rock domain. The detection and characterization of such altered domains are crucial to understanding local hydrogeological conditions. Here, the target is the San Luis area, located in the northern part of the Estibaná River watershed, within the Los Santos Province in the central region of the Isthmus of Panama. First, a detailed geological survey was carried out to better constrain the tectonic structures. Then, two geological sections were developed based on two 2D electrical resistivity tomographies. A geoelectrical simulation process was conducted in both sections to set theoretical models whose model responses (synthetic field data set) would be consistent with the observations. After appropriate selection of the inversion parameters by using the Boundless Electrical Resistivity Tomography (BERT) code, the observations were processed, resulting in low calculation errors (2 < 0.51). Based on the superficial geological information and the results of the geophysical modelling, two profiles were established, depicting the lateral and in-depth distribution of rocks and sediments. The limit of the Ocú-Parita fault zone was identified as well. The results of the 2D inversion of the synthetic data, obtained with the established theoretical models, are consistent with the 2D inversion of the observations. Electrical resistivity tomography studies can be useful in establishing groundwater management models, particularly in areas that experience severe water scarcity during the dry season.

Authors: Thuany Mabliny , Witthöft Anja , Valero David , Forte Pedro , Weiss Katja , Scheer Volker , Nikolaidis Pantelis Theo , Andrade Marilia Santos , Cuk Ivan , Knechtle Beat
Published: September 2024

Purpose

This study aimed to verify participation and performance in all road and trail-based races in Switzerland over two decades (1999–2019).

Methods

This is a secondary data-based study. We used 1,149,182 race records (788,818 from men and 360,364 from women) from 407,944 unique finishers of the 5 km, 10 km, half-marathon, marathon, and ultra-marathon races in Switzerland, between 1999 and 2019. Data included the athletes’ genders, ages, race distances, and types of races (road or trail). The mento- women ratio was calculated and box plots were used to present differences according to gender, age groups, and race distances in both terrains. Differences between the groups were calculated.

Results

The men-to-women ratio has generally decreased in all race distances over the years. Runners competing in roadbased races were faster than those in a trail run in all distances. Men had faster finish times than women independent of age, except those competing in 10 km trail races. In road-based races, the men-to-women ratio was higher among older marathoners, while for trail runs, a higher men-to-women ratio was shown for older half-marathoners and participants in 10 km races. For 5 km, 10 km, half-marathon, and ultra-marathon races, a decrease in running speed differences was shown until the age of 50 years.

Conclusions

In Switzerland, most of the runners competed in road-based races, but the interest in trail running has increased. The men-to-women ratio declined over time, which could show an increase in the interest of women to participate in endurance activities.
Possibility to measure the volume of coronary sinus in contrast-enhanced computed tomography
Authors: Młynarska Agnieszka , Młynarski Rafał
Published: September 2024

Introduction

Modern imaging techniques such as computed tomography (CT) can help in the assessment of coronary sinus volume in a vitro manner, but there is no comprehensive research on this topic so far. Hence, we decided to develop a methodology for measuring the volume of the coronary sinus in multi-detector CT and to try to apply it in practice.

Material and methods

Forty-nine patients (22 men) were included in this research, with a mean age of 70.08 ± 13.6 years. Scanning with retrospective ECG-gating was performed using a Toshiba Aquilion 64 (slice: 0.5 mm; helical pitch: 12.8; rotation time: 0.4 s). 80 ± 20 cm3 of non-ionic contrast was administered to each patient. The volume of coronary sinus and other data measurements were performed using Vitrea 2 workstations. The organ volume measurement function was used to measure volume objects in CT scans. To standardise the measurements, they were all performed to the place where the vein of Marshall reaches the coronary sinus. In cases of loss of vein of Marshall, the first lateral vein was used as the junction between the coronary sinus and the great cardiac vein.

Results

The coronary sinus volume varied from 0.96 cm3 to 8.52 cm3. The average volume was 3.71 ± 1.64 cm3. There was a significant correlation between end diastolic volume and coronary sinus volume (r = 0.33, p = 0.02). In most cases the quality of visualisation was good – the average was calculated as 4.16 ± 0.87. The Thebesian valve was present in 22 cases (44.9%); however, no statistical relationship between the presence of the Thebesian valve and coronary sinus was observed.

Conclusions

It is possible to visualise and calculate the volume of the coronary sinus in cardiac CT.

Introduction: Viral Hepatitis C is a public health problem that affects approximately 58 million people worldwide. In 2021, its prevalence in Cameroon was 1.1% in the general population and some small biased studies indicate a range of 0 to 7.2% in the Cameroonian population infected with HIV. Methods: The general objective of this study was to evaluate the acceptability of task delegation for the treatment of Hepatitis C within HIV care services by general practitioners in public health facilities in the region. of the center involved in the DEHEP-C project in 2022. This was a cross-sectional study of HIV patients cared for in 05 public health facilities in the said region comprising two components, one descriptive and the other analytical. The results were presented with a 95% confidence interval, odds ratios (crude and adjusted) and significance with value P˂0.05. Results: 510 patients were included, the general satisfaction of PLHIV with the services offered by the FOSAs in the study was 75%. The acceptability of the delegation of tasks for the treatment of Hepatitis C within HIV care services by general practitioners by the respondents was 89%. Factors such as residing in a rural area (aOR = 1.63 95% CI = 1.40 – 3.78 ; p<0.01 ), being a regular patient in a 4th category FOSA ( aOR = 1.59 95% CI = 1.43 – 3.47 ; p<0.01 ), following 3rd line treatment (aOR = 0.27 95% CI = 0.10 – 0.69; p<0.01 ) turned out to be significant factors of the acceptability of task delegation. Conclusion: The majority of PLHIV interviewed during this study were in favor of the delegation of tasks for the treatment of Hepatitis C by general practitioners in patients infected with HIV within the CTA or UPEC of the Central region.

The Role of Continuity of Care (CoC) in Supporting Pregnant Women at Risk of Chronic Energy Deficiency (CED) in Improving Nutritional Status: A Case Report
Authors: Alfina Sayyidati Tazkiya , Setyowati Arin Tri Wahyu , Wuni Aulia Az Zahra , Andriyanti Andriyanti , Jayanti Ratna Dwi
Published: September 2024

Background: Nutritional issues in pregnant women occur during the 1,000 Days of Life (HPK) period. If nutritional problems during pregnancy are not addressed, they can disrupt fetal development. The government has undertaken efforts such as providing supplementary feeding (PMT). This PMT activity should also be accompanied by nutritional education to promote behavioral change. Midwives are among the healthcare professionals who can provide comprehensive support. This support is aimed at optimizing continuous midwifery care, with the expectation of reducing the impact of Chronic Energy Deficiency (CED) on both pregnant women and their fetuses. Methods: This case report is compiled using a descriptive method with a case study approach. The researcher supported Continuity of Care (CoC) to one patient in the working area of the Surabaya Community Health Center, from the pregnancy period through to the postpartum period and the newborn phase. Case Presentation: A 20-year-old pregnant woman was identified as at risk for Chronic Energy Deficiency (CED) due to a measurement of Mid-Upper Arm Circumference (MUAC) < 23.5 cm. The woman received continuous support, including monitoring her intake of prenatal vitamins, Antenatal Care (ANC) support, counseling, and nutritional education. By the end of the pregnancy, there was an increase in her MUAC, and she was no longer at risk of CED. Conclusion: With support in the form of monitoring and holistic, comprehensive, and collaborative midwifery care from the beginning of pregnancy, optimal care targets can be achieved. The role of support throughout the pregnancy and postpartum period has been carried out effectively, resulting in the mother being free from the risk of Chronic Energy Deficiency (CED) and the baby not experiencing Low Birth Weight (LBW).

In the current study, the adsorption capacity of Tella residues (residues of fermented alcoholic beverage) for quantitative uptake of Cu(II), Cd(II), Zn(II) and Pb(II) was evaluated. Chemical treatment of the local beer residue (LBR) has improved the removal efficiency of the adsorbent, which was achieved at pH = 5, 1.0 g adsorbent, 50 mg/L initial concentration, 180 min contact time and agitation speed of 100 rpm. The adsorption was found to fit the Langmuir adsorption isotherm model, and the theoretical equilibrium capacities were well fitted with the experimental equilibrium capacities, resulting in chemical adsorption (chemisorptions) on the adsorbent surface while the equilibrium kinetics follows the pseudo-second-order. The adsorption capacity (Qo) of LBR decreases in the following order: Zn(II) > Cu(II) > Pb(II) > Cd(II) as metal concentration ranged from 20-200 mg/L. Thermodynamic parameters, including standard free energy (ΔG°), enthalpy (ΔH°) and entropy (ΔS°) were calculated to predict the nature of adsorption. The negative values of ΔG° and the positive value of ΔH° indicate that the adsorption process was spontaneous and endothermic. Adsorption capacities were found to increase when the temperature ranged from 25-60 °C. Thus, the findings suggest a promising application of LBR as an alternative low-cost novel adsorbent for the removal of toxic heavy metals from wastewater.

The reaction of N-morpholine-N′-benzoylthiourea (L: HBMOR) and lead(II) acetate gave a neutral, stable metal(II) complex of type ML2. The Pb(II) complex crystallized in a monoclinic crystal system with P21/n space group. The complex was further characterized by spectroscopic and microanalytic analyses. The solvent extraction behaviors of Pb(II) and Cu(II) ions were investigated in aqueous media containing HBMOR/CHCl3 as extracting reagents. The solvent extraction of Pb(II) and Cu(II) ions from solutions of varying pH, varying concentrations of mineral acids (HCl, HNO3 and H2SO4), varying concentrations of masking agents (EDTA, KCN and KH[C8H6O4]) and varying concentrations of salting-out agents (NaCl, Na2SO4, KNO3) in chloroform solutions of HBMOR were studied. Pb(II) and Cu(II) ions were quantitatively extracted at pH = 7 in 10 min (HCl = 0.01 M) and pH = 8 in 5 min (H2SO4 = 0.01 M), respectively. The Pb(II) ions were quantitatively extracted with minimal interference from EDTA (0.01 M), KCN (0.50 M), and potassium hydrogen phthalate (1.0 M), while the Cu (II) ions were extracted with EDTA (1.0 M), KCN (1.0 M) and potassium hydrogen phthalate (0.01 M). The order of increasing interference for the extraction of Pb(II) and Cu(II) ions was KCN > potassium hydrogen phthalate > EDTA. Sodium sulfate (0.01 M) in HCl enhanced the extraction of Pb(II) ions, while sodium chloride (0.50 M) in HCl enhanced the extraction of Cu(II) ions. pH0.5 values of 0.67 and 2.70 were obtained for Pb(II) and Cu(II) ions, respectively, indicating that the separation of the two metal ions is favorable with HBMOR.

The Usefulness of Information Contained in Financial Statements
Authors: CIESLAK Marek
Published: September 2024

The paper delves into the efficacy of financial statements, scrutinizing the quality determinants and the role of fair value in financial reporting. It argues that while accounting standards aim to enhance the quality of financial statements for better capital market decisions, the real challenge lies in balancing the usefulness and reliability of the information provided. The conclusion suggests a potential solution: allowing entities to choose between historical cost and fair value for financial reporting, which could lead to industry-specific practices that optimize the trade-off between information utility and reliability. This choice could foster a competitive environment where the most effective valuation method prevails, ultimately benefiting the transparency and functionality of financial statements.

Abstract. The Airborne Hyper-Angular Rainbow Polarimeter (AirHARP) is a new imaging polarimeter instrument capable of sampling a single Earth target from up to 120 viewing angles, in four spectral channels, and in three linear polarization states across a 114° field of view (FOV). AirHARP is telecentric in the image space and simultaneously images three linear polarization states with no moving parts. These two aspects of the design allow for a simple and efficient quantitative calibration. Using coefficients derived at the center of the lens and the detector flatfields, we can calibrate the entire AirHARP sensor in a variety of laboratory, field, and space environments. We show that this telecentric calibration technique yields a 1σ absolute uncertainty of 0.25 % in degree of linear polarization (DOLP) in the laboratory for all channels and for pixels around the optical axis. To validate across the FOV, we compare our multi-angle reflectance and polarization data with the Research Scanning Polarimeter (RSP) over targets sampled during the NASA Aerosol Characterization from Polarimeter and Lidar (ACEPOL) campaign. We use the error-normalized difference technique to estimate how well the instruments compare relative to their error models. We find that AirHARP and the RSP reasonably agree for reflectance and DOLP within 2 standard deviations of their mutual uncertainty at 550, 670, and 870 nm and over a limited set of ocean and desert scenes. This calibration technique makes the Hyper-Angular Rainbow Polarimeter (HARP) design attractive for new spaceborne climate missions: HARP CubeSat (2020–2022), HARP2 (2024–) on the NASA Plankton, Aerosol, Cloud, ocean Ecosystem (PACE), and beyond.
