Authors: Сосницький Степан
Published: February 2024

Розглянуто вплив моменту кількостей руху на стабілізацію руху в задачі трьох тіл. Отримано достатні умови обмеженості руху як в обмеженій задачі трьох тіл, так і в її загальному випадку. Ключовою за цих умов є роль моменту кількостей руху. Хоча в просторовій круговій обмеженій задачі трьох тіл момент кількостей руху не є інтегралом руху, а лише складовою частиною інтеграла Якобі, однак забезпечує обмеженість руху нескінченно малої частки за певних додаткових умов. Проведено порівняльний аналіз загальної і обмеженої задач трьох тіл.
Динаміка твердого тіла з внутрішніми степенями свободи, обумовленими рідиною з вільною поверхнею
Authors: Лимарченко Олег
Published: February 2024

Задачі динаміки твердого тіла з внутрішніми степенями свободи завжди викликали теоретичний і практичний інтерес. Складність дослідження таких об’єктів обумовлено, перш за все, необхідністю проводити вивчення поведінки системи у сумісній постановці. Особливі проблеми виникають у випадках, коли внутрішні степені свободи визначають компоненти, які мають континуальну структуру. При цьому для опису поведінки системи буде потрібно використовувати математичну модель неоднорідної математичної структури (система звичайних диференціальних рівнянь для руху твердого тіла і рівняння з частинними похідними для опису континуальної складової), що є достатньо складним. Додаткові складнощі виникають у випадку руху твердих тіл із рідиною, коли рух твердого тіла описують з лагранжовими змінними, а рух рідини — з ейлеровими. Крім того, складною проблемою є також визначення сил взаємодії між компонентами. Однією з важливих у теоретичному і практичному планах є задача про рух тіла-носія з рідиною з вільною поверхнею, яку досліджуємо у цій роботі. Головну увагу приділено випадкам, коли рух механічної системи циліндричний резервуар – рідина з вільною поверхнею відбувається у нелінійному діапазоні збурень вільної поверхні рідини при значному прояві фактора сумісності руху і при кутових рухах тіла-носія. На основі проведених досліджень показано особливості розвинення резонансних процесів у системі. При дослідженні коливань системи на маятниковому підвісі встановлено, що при зменшенні довжини підвісу в системі відбувається зміна черговості розташування форм коливань при їхньому розміщенні в порядку зростання власних частот. Для всіх типів резонансів показано, що виходу системи у класичному сенсі на усталений режим коливань взагалі не відбувається, і це підтверджено експериментальними результатами.

Solar-like oscillations have been detected in thousands of stars thanks to modern space missions. These oscillations have been used to measure stellar masses and ages, which have been widely applied in Galactic archeology. One of the pillars of such applications is the

ν

scaling relation: the frequency of maximum power

ν

, assumed to be proportional to the acoustic cutoff frequency, ν
ac, scales with effective temperature and surface gravity. However, the theoretical basis of the

ν

max

scaling relation is uncertain, and there is an ongoing debate about whether it can be applied to metal-poor stars. We investigate the metallicity dependence of the

ν

max

scaling relation by carrying out 3D near-surface convection simulations for solar-type stars with [Fe/H] between −3 and 0.5 dex. First, we found a negative correlation between ν
ac and metallicity from the 3D models. This is in tension with the positive correlation identified by studies using 1D models. Second, we estimated theoretical

ν

max

values using velocity amplitudes determined from first principles, by quantifying the mode excitation and damping rates with methods validated in our previous works. We found that 

ν

max

does not show correlation with metallicity at solar effective temperature and surface gravity. This study opens an exciting prospect of testing the asteroseismic scaling relations against realistic 3D hydrodynamical stellar models.
Multiwavelength Analysis of the Supernova-associated Low-luminosity GRB 171205A
Authors: Li Xiu-Juan , Zhang Zhi-Bin , Huang Yong-Feng , Xu Fan
Published: February 2024

Multiwavelength properties of the nearby supernova (SN)-associated low-luminosity GRB 171205A are investigated in depth to constrain its physical origin synthetically. The pulse width is found to be correlated with energy with a power-law index of −0.24 ± 0.07, which is consistent with the indices of other SN-associated gamma-ray bursts (SN/GRBs) but larger than those of long GRBs. By analyzing the overall light curve of its prompt gamma rays and X-ray plateaus simultaneously, we infer that the early X-rays together with the gamma-rays should reflect the activities of the central engine, while the late X-rays may be dominated by the interaction of external shocks with circumburst material. In addition, we find that the host radio flux and offset of GRB 171205A are similar to those of other nearby low-luminosity GRBs. We adopt nine SN/GRBs with measured offset to build a relation between peak luminosity (L

γ,p
) and spectral lag (τ) as L

γ,p
∝ τ
−1.91±0.33. The peak luminosity and the projected physical offset of 12 SN/GRBs and 10 kilonova-associated GRBs are found to be moderately correlated, suggesting their different progenitors. The multiwavelength afterglow fitted with a top-hat jet model indicates that the jet half-opening angle and the viewing angle of GRB 171205A are ∼34.°4 and 41.°8, respectively, which implies that the off-axis emissions are dominated by the peripheral cocoon rather than the jet core.
Eccentricity Distribution beyond the Snow Line and Implications for Planetary Habitability
Authors: Kane Stephen R. , Wittenmyer Robert A.
Published: February 2024

A fundamental question in the study of planetary system demographics is: how common is the solar system architecture? The primary importance of this question lies in the potential of planetary systems to create habitable environments, and dissecting the various components of solar system evolution that contributed to a sustainable temperate surface for Earth. One important factor in that respect is volatile delivery to the inner system and the dependence on giant planets beyond the snow line as scattering agents, particularly as such cold giant planets are relatively rare. Here, we provide an investigation of the eccentricity distribution for giant planet populations both interior and exterior to their system snow lines. We show that the median eccentricity for cold giants is 0.23, compared with a far more circular orbital regime for inner planets. We further present the results of a dynamical simulation that explores the particle scattering potential for a Jupiter analog in comparison with a Jupiter whose eccentricity matches that of the median cold giant eccentricity. These simulations demonstrate that the capacity for such an eccentric cold giant system to scatter volatiles interior to the snow line is significantly increased compared with the Jupiter analog case, resulting in a far greater volume of Earth-crossing volatiles. Thus, many of the known systems with cold giant planets may harbor water worlds interior to the snow line.

Authors: Dolcetti Vincenzo , Ruggiero Sergio , Pellini Raul , Mercurio Anastasia , Vidiri Antonello
Published: February 2024

This case study presents a 66-year-old man referred to the Otolaryngology and Head and Neck Surgery department due to a one-history of persistent pain in the left posterior cervical region. No abnormalities were detected in the oral and pharyngeal regions during clinical and endoscopic examinations. Subsequently, a magnetic resonance imaging revealed a lesion (14 x 12 x 14 mm) into the left parapharyngeal space, with high signal intensity on T2-weighted images, enhancement after contrast medium, restricted signal on diffusion weighted imaging and high vascularization on perfusion MRI. The histological examination of the lesion led to a diagnosis of myopericitoma. Post-surgery, no adjuvant therapy was administered. Myopericytomas are rare soft-tissue benign neoplasms, predominantly reported in extremities, with a limited number of cases in the head and neck region and almost never described in the literature with elective localization in the parapharyngeal space.
Litigiosidad en torno a las reformas de Carlos III y Carlos IV en algunas cofradías valencianas de la Ribera Alta, L’Horta Nord y Valencia
Authors: Montojo Montojo Vicente , Blanes Andrés Roberto
Published: February 2024

La existencia de fondos documentales de cofradías y hermandades en archivos parroquiales y municipales valencianos permite valorar su importancia a través de su incidencia a modo de conflictos en procesos judiciales de otros fondos archivísticos, como los judiciales del Archivo Diocesano de Valencia, el Archivo del Reino de Valencia y el Archivo Histórico Nacional (fondo Real Consejo de Castilla). En este último se acumuló una serie de procesos de apelación superior a la del Tribunal de Obras Pías de la jurisdicción eclesiástica diocesana y a la de la Real Audiencia de Valencia, cuyos documentos se conservan en el Archivo del Reino de Valencia. Esto sucedió así porque las reformas de nueva planta suprimieron la jurisdicción del Real Consejo de Aragón, que pasó al de Castilla. Se plantea en este texto un primer nivel de análisis de la conflictividad de cofradías y hermandades en tres periodos, como fueron los gobiernos de Grimaldi y Floridablanca en el reinado de Carlos III, y el de Godoy en el de Carlos IV, caracterizados por las reformas derivadas del expediente general de investigación de cofradías y de una primera desamortización de propiedades.

Study of the left ventricle in cirrhosis and correlation with the Model for End-stage Liver Disease score
Authors: Chigullapalli Sridevi , Saha Debapriya , Khan Anish Kumar
Published: February 2024

Background:

Recent research has increased amount of evidence for heart disease associated with cirrhosis, which has led to the definition of the entity cirrhotic cardiomyopathy. The present study was conducted with an objective to evaluate the clinical, biochemical, and echocardiographic evaluation of patients presenting with cirrhosis and to find its correlation between the severity of cirrhosis and cardiac dysfunction.

Materials and Methods:

The present study was a case–control study conducted from July 2021 to September 2022. All the cases were examined using two-dimensional echocardiography, electrocardiogram, and other laboratory parameters. The Model for End-stage Liver Disease (MELD) score was calculated for each of the cases.

Results:

Alcohol ingestion was the most common (76%) etiological factor associated with cirrhosis. There was a significant difference between the QTc interval among cases and controls and among the MELD score group. A significant difference was observed in the left ventricular end-systolic diameter (LVESD), left ventricular end-diastolic diameter (LVEDD), interventricular septal thickness (IVST), left atrial diameter, cardiac output (CO), E (Peak velocity flow in early diastole)/A (peak velocity flow in late diastole), E (Peak velocity in early diastole)/e’(passive left ventricular filling during early diastole), and deceleration time among the cases and controls.

Conclusion:

Based on our results, we conclude that liver cirrhosis cases revealed increased cardiac dysfunction with an increase in the MELD severity, particularly involving left ventricular diastolic dysfunction. Cirrhotic patients presented with increased CO and decreased E/A ratio. With increasing MELD score, there was a significant increase in the LVESD, LVEDD, IVST, and CO and a decreased E/A ratio.
Prevalence and Predictors of Gestational Diabetes Mellitus and Overt Diabetes in Pregnancy: A Secondary Analysis of Nationwide Data from India
Authors: Basu Saurav , Maheshwari Vansh , Gokalani Rutul , Lahariya Chandrakant
Published: February 2024

Background:

This analysis was conducted to understand prevalence and determinants of gestational diabetes mellitus (GDM) and (overt) diabetes in pregnancy (DIP) in India, and also ascertain their health-seeking behaviour.

Materials and Methods:

The authors analysed data from the fifth National Family Health Survey of India. Binary logistic regression was used to assess the factors independently associated with GDM and (overt) DIP.

Results:

The weighted prevalence of GDM was 4.2% (95% confidence interval [CI]: 3.9–4.5), and the age-adjusted prevalence was 5.4% (95% CI: 4.5–6.4). The prevalence of GDM increased with age. The weighted prevalence of (overt) DIP was 0.38% (95% CI: 0.30–0.48), and the age-adjusted prevalence was 1.04% (95% CI: 0.64–1.68). On adjusted analysis, it was found that increasing age and obesity had significantly higher odds of having GDM. Higher odds of access to private facilities were found amongst women with higher education and those who were overweight. Significant regional variation in the prevalence of GDM was observed, with a very low burden observed in northeastern states and a comparatively higher burden in Central, Western and Southern Indian states.

Conclusions:

There is an increasing prevalence of GDM in India. Strengthening primary health systems to enhance GDM-related service availability, quality and delivery could be logical policy intervention.

Authors: Karol Sunidhi , Thakare Meenal M.
Published: February 2024

In India, the immunisation programme has made a few technology-dependent advancements. The electronic vaccine intelligence network is to manage the immunisation supply chain and logistics. eVIN ensures the timely and effective distribution of vaccines, contributing to successful immunisation campaigns. The other platform is Co-WIN, which served as the digital backbone for India’s COVID-19 vaccination programme. It facilitates the registration and scheduling of vaccine appointments, tracking of vaccination coverage, monitoring adverse events, enabling a swift and organised response to the pandemic. The U-WIN (universal immunisation) is a comprehensive digital system aligned with the Ayushman Bharat Digital Mission. It connects various key components, including the Healthcare Professional Registry, Healthcare Facility Registry and Ayushman Bharat Health Account. This integrated approach aims to strengthen the Universal Immunisation Programme by leveraging digital technology. Overall, these digital initiatives represent a significant leap in India’s immunisation efforts. They enhance data management, supply chain logistics and healthcare infrastructure while ensuring that the immunisation programme is efficient, accessible and responsive to the needs of the population. This integration of technology and health-care systems is a crucial step toward achieving universal immunisation coverage in the country.

HER2-Low Breast Cancer: Now and in the Future
Authors: Kang Sora , Kim Sung-Bae
Published: February 2024

Breast cancer is a heterogeneous disease, and its subtypes are characterized by hormone receptor and human epidermal growth factor receptor 2 (HER2) expression status. “HER2-low” tumors, which exhibit a low level of HER2 expression (immunohistochemistry 1+ or 2+ without gene amplification), were conventionally considered not amenable to anti-HER2 targeting agents based on the results of a phase III trial of trastuzumab. However, this perspective is being challenged by the emergence of novel anti-HER2 antibody-drug conjugates, such as trastuzumab-deruxtecan. These innovative therapies have demonstrated remarkable efficacy against HER2-low breast cancer, shedding new light on a previously overlooked category of breast cancer. Such promising results highlight the need for in-depth investigations of the biology and prognostic implications of HER2-low tumors. In this review, we comprehensively summarize the current evidence surrounding this topic and highlight areas that warrant further exploration and research in the future.

Published: February 2024

Purpose Chemotherapy has been the primary treatment for patients with B-cell acute lymphoblastic leukemia (B-ALL). However, there are still patients who are not sensitive to chemotherapy, including those with refractory/relapse (R/R) disease and those experiencing minimal residual disease (MRD) re-emergence. Chimeric antigen receptor-T lymphocytes (CAR-T) therapy may provide a new treatment option for these patients.Materials and Methods Our institution conducted a single-arm prospective clinical trial (ChiCTR-OPN-17013507) using CAR-T-19 to treat R/R B-ALL and MRD re-emergent patients. One hundred and fifteen patients, aged 1-25 years (median age, 8 years), were enrolled, including 67 R/R and 48 MRD re-emergent CD19-positive B-ALL patients.Results All patients achieved morphologic complete remission (CR), and within 1 month after infusion, 111 out of 115 (96.5%) patients achieved MRD-negative CR. With a median follow-up time of 48.4 months, the estimated 4-year leukemia-free survival (LFS) rate and overall survival (OS) rate were 68.7%±4.5% and 70.7%±4.3%, respectively. There were no significant differences in long-term efficacy observed among patients with different disease statuses before infusion (4-year OS: MRD re-emergence vs. R/R B-ALL, 70.6%±6.6% vs. 66.5%±6.1%, p=0.755; 4-year LFS: MRD re-emergence vs. R/R B-ALL, 67.3%±7.0% vs. 63.8%±6.2%, p=0.704). R/R B-ALL patients bridging to transplantation after CAR-T treatment had a superior OS and LFS compared to those who did not. However, for MRD re-emergent patients, there was no significant difference in OS and LFS, regardless of whether they underwent hematopoietic stem cell transplantation or not.Conclusion CD19 CAR-T therapy effectively and safely cures both R/R B-ALL and MRD re-emergent patients.

Published: February 2024

SMARCB1 or SMARCA4-deficient sinonasal carcinoma or thoracic undifferentiated tumor has aggressive nature with a poor prognosis. Patients with this disease were diagnosed by immunohistochemistry or next-generation sequencing. Those who were able to receive a surgery tended to be cured, while the others treated with chemotherapy, radiation therapy, or immune checkpoint inhibitor were often insensitive to these therapies. However, one having CD274 (PD-L1) amplification showed the response to immune checkpoint inhibitor and a good prognosis. We believed that this report could provide promising information for determining the optimal treatment option.
Association between Iron–Folic Acid Supplementation during Pregnancy and Maternal and Infant Anemia in West Java, Indonesia: A Mixed-Method Prospective Cohort Study
Authors: Sartika Ratu Ayu Dewi , Wirawan Fadila , Putri Primasti Nuryandari , Mohd Shukri Nurul Husna
Published: February 2024

The Indonesian government has provided iron–folic acid (IFA) supplementation in response to maternal pregnancy iron-deficiency anemia. However, community-based cohorts on IFA’s effects on maternal and infant anemia are limited. A mixed-method study design with a primary longitudinal cohort was used to observe the association between IFA and anemia in mothers and infants. Iron–folic acid supplementation was observed throughout pregnancy. Anemia status was based on a single hemoglobin assessment using HemoCue Hb 201 + in the second or third trimester of pregnancy for the mother and at birth for the infant. Qualitative data were collected via in-depth interviews (IDIs) and a forum group discussion (FGD). Iron–folic acid supplementation with > 180 tablets throughout pregnancy was associated with lower pregnancy anemia (adjusted relative risk [aRR] = 0.25, 95% CI: 0.092–0.664, P = 0.006) after adjusting for potential confounding variables. Supplementation with IFA was not associated with infant anemia (RR = 1.033, 95% CI: 0.70–1.54, P = 0.873 for 90–180 tablets and RR = 1.07, 95% CI 0.70–1.63, P = 0.774 for > 180 tablets). The IDIs and FGD suggested that IFA and multivitamin content knowledge, IFA consumption monitoring, and paternal involvement were important in IFA supplementation and effectiveness in reducing anemia. Iron–folic acid supplementation was associated with reduced maternal but not infant anemia. Because maternal anemia is associated with infant anemia, an anemia monitoring program for women in early pregnancy is vital in addressing infant health. Paternal involvement was also identified as a major factor in maternal and child health.
An overview of ethical issues in neuromarketing: Discussion and possible solutions
Authors: Mouammine Yahia , Azdimousa Hassan
Published: February 2024

The emergence of new areas of investigation frequently elicits a division of opinion among the scientific community, particularly when human participants are involved. Consumer neuroscience, commonly referred to as neuromarketing in popular discourse, has given rise to a plethora of ethical predicaments and moral uncertainties in academic circles. In the absence of intervention, these obstacles possess the capacity to impede the advancement of this nascent discipline. Although certain ethical concerns may appear exaggerated, it is imperative for both researchers and neuromarketing firms to maintain rigorous data protection protocols and honor the confidentiality of study participants. The concept of neuromarketing, as commonly portrayed in scholarly works, denotes the intersection of the fields of neuroscience and marketing. The present definition served as a catalyst for our investigation into ethical considerations as expressed in neuromarketing literature, situated within the theoretical constructs of neuroethics and marketing research ethics. This paper examines the ethical dilemma from two perspectives, namely marketing research and neuroethics. The following discourse delves into the ethical concerns derived from the existing neuromarketing literature, providing viable solutions and guidelines to effectively navigate this unexplored ethical landscape.

Considerando que o infanticídio pode se contrapor aos interesses entre a prole e os pais, assim como entre os dois sexos, o comportamento agressivo de adultos contra os infantes é considerado uma peça fundamental como estratégia reprodutiva dos organismos. Assim, o presente artigo visa a descrever quais os tipos de infanticídio, explicitando quais as vantagens de cada comportamento infanticida biparental. A pesquisa foi realizada utilizando o software Publish or Perish©, com palavras-chave, como “etologia”, “infanticídio” e “mamíferos”, em inglês, português e espanhol. Após a busca, selecionaram-se 51 obras dentre artigos científicos, teses e dissertações, destacando um período de 40 anos. Organizou-se de maneira sistemática, separando as referências em duas classes: (a) fisiológica e (b) sociobiológica/ecológica. Os resultados indicam que o comportamento de infanticídio em mamíferos pode ser influenciado por diferentes fatores, tais como estresse ambiental, vias hormonais, sobretudo a oxitocina e a vasopressina. Além disso, os estudos mostraram que há diferenças individuais na resposta comportamental ao cuidado parental e ao comportamento infanticida, influenciadas tanto pelo genótipo quanto pelo ambiente em que os indivíduos foram criados. O comportamento de infanticídio também pode ser visto como uma estratégia adaptativa parental para aumentar as chances de sobrevivência e reprodução futura. Em última análise, os resultados deste estudo destacam a complexidade do comportamento de infanticídio em mamíferos, evidenciando a importância de considerar os fatores fisiológicos, sociobiológicos e ecológicos em sua análise e interpretação.

The objectives of this study are: 1) To examine and analyze the role of cultural factors as differentiators of loyal debtors and debtors who have the potential to move. 2) To examine and analyze the role of social factors as differentiators of loyal debtors and potentially moving debtors. The research approach used in this study is quantitative research with discriminant analysis research methods. Discriminant analysis is a data analysis technique where the specific variable (variable Y) is categorical data (nominal) while the independent variable (variable X) is ordinal data. As a result of the analysis, it can be concluded that the debtor discriminator that is able to distinguish loyal debtors and those who have the potential to move is the Bud variable. So, if the debtor does not understand about Sos, Pri, and Psi, then it does not matter because the one who is able to discriminate against the three categories of debtors is Bud.

Teaching Algebraic Structures might represent some learning and understanding difficulties for the freshmen students of Industrial Processes Engineering at Universidad Autónoma de Sinaloa. In order to investigate the cause or causes of this situation, a diagnostic instrument (test) consisting of several questions was developed and was applied to a 40 engineering students’ group, about algebraic structures previous knowledge, mostly related with the conception of the real numbers laws. Although the subject of the real numbers laws is addressed for the first time in junior high and then delves in high school, the students reach the university without domain and sometimes without any knowledge of the subject. It will be part of this paper to present and discuss the results found in the diagnosis. It also highlights the importance and benefits of using a diagnostic instrument in subjects that are known to be difficult for students. Among the results that have been obtained, it is highlighted that there has been confusion about some properties of real numbers among students, and they make mistakes when trying to put them into practice. In particular, they often make mistakes when combining the implementation of a property within a subset of real numbers.

Published: February 2024

The orange juice production industry in Veracruz generates a large amount of peel waste, which is both an economic and environmental problem. One way to repurpose these residues is to create biochar, which can be used in agriculture to improve fertility and crop productivity. The aim was to determine how the addition of orange biochar affected the physical and chemical properties of different soils, as well as corn growth (Zea mays L.). The experimental design was completely randomized in factorial arrangement (3 x 4): three soil types (clay loam, sandy, and sandy loam), four biochar doses (0, 18, 90, and 180 equivalent to Mg ha-1), and nine replicates per treatment (n = 108). The highest biochar dose presented significant differences (p ≤ 0.05) in almost all soil physical and chemical variables, except for moisture holding capacity, which varied significantly only in the sandy loam soil with the medium and high doses. In the clay loam soil, the higher dose significantly reduced stem width, aerial biomass, and leaf area. In sandy soil, the medium dose increased stem height and root biomass. In addition, in the sandy loam soil, the highest dose increased stem height and width. The remaining growth variables showed no significant differences between doses or soil types. In conclusion, the use of this biochar altered the physical and chemical properties of the three different soils, as well as having a significant impact on some maize growth variables.

Published: February 2024

Poultry slaughterhouses discharge large quantities of effluents that can be treated biologically. The objective of this study was to evaluate the chemical oxygen demand (COD) removal efficiency of an upflow anaerobic filter (UAF) with effluents from a poultry slaughterhouse, using volcanic stone (tezontle) as a support medium. Effluent characterization was carried out in accordance with Mexican official standards and standard methods. The support medium was inoculated with activated sludge from an urban wastewater treatment plant. The filter was operated in continuous flow with applied volumetric loads (AVL) of 1, 1.5, 2, 2.5, and 3 kg COD m-3 d-1 and hydraulic retention times (HRT) of 5.8, 3.8, 2.9, 2.3, and 1.9 days. An analysis of variance (ANOVA) was performed, and significant differences were determined for each AVL using the Krustall-Wallis method. The results obtained in the gradually applied AVL were 26.1, 53.2, 40.1, 17, and 49.7 % COD removal. However, in the AVL of 2 and 2.5 kg COD m-3 d-1, there was a decrease in the removal, which is attributed to the destabilization of the system due to the increase in loads. The maximum methane production was 125 mL at an AVL of 3 kg COD m-3 d-1, with a methane yield (YCH4) of 0.082 LCH4 g-1 COD-1rem. With no increase in methane production at each AVL, the theoretical yield of 0.328 LCH4 g-1 COD-1rem. was not met. The upflow anaerobic filter demonstrated its efficiency with a poultry effluent, with maximum COD removal greater than 50 %; however, more acclimatization time is required for the formation of biofilm in the support medium, a pretreatment that removes the high organic load and allows for gradual biogas production.

The capital market has an important role in the financial sector because it offers new alternatives for the business world to obtain sources of business financing in addition to adding new alternatives for investors to invest outside of banking and other forms of investment. However, investing in the capital market also has higher risks compared to investing in other fields. The Capital Markets Law regulates the issue of obligations to comply with the principle of openness and regulates the issue of consequences and responsibility for losses as well as criminal threats for capital market players who do not carry out the obligations of the principle of openness. The problem studied in this writing is legal protectionbailout investors againstWindows Dressing emitaccording to the Capital Markets Law. This writing was carried out using normative juridical methods. The writing approach uses a statutory approach. The data source used in this writing is a secondary data source which was then analyzed qualitatively. The results obtained in this research are that legal protection for investor bailouts is regulated in the Capital Markets Law Article 114 paragraph (1), Article 111 paragraph (2) letter b which requires issuers to provide compensation to investors who are harmed due to the issuer's errors or negligence.
Dialogues across Languages: Hermeneutic Perspectives on Interpreting Multilingual Conversations
Authors:   St. Michael’s College of Iligan City, Quezon Ave., Iligan City, MAED, TESOL Stephanie L. Colorada
Published: February 2024

Multilingual conversations are now commonplace in our increasingly interconnected world, promoting cross-cultural exchanges and enhancing the diversity of human discourse. But there are a lot of difficulties because of this linguistic diversity, especially when it comes to interpretation. The subtle and frequently complex nature of multilingual dialogues, where interpretations may differ not only between languages but also have distinct cultural connotations, is the central issue of this study. This study's major objective was to better understand the challenges associated with translating conversations between several languages by applying hermeneutic perspectives. This study attempted to uncover the intricate layers of meaning interwoven in these exchanges by analyzing the ways in which languages, cultures, and the interpretation process interact. The research employed a qualitative research method, utilizing a hermeneutic approach to explore and interpret the complexities of multilingual conversations. This method aligned with the study's objective of delving into the nuanced meanings embedded in the dialogues across languages and cultures. This qualitative research design aimed to uncover the depth of interpretation in multilingual conversations, providing a rich and contextually grounded exploration of the phenomena under investigation. As a result, It is clear from the foregoing that cultural sensitivity is essential to successful multilingual interpretation. Interpreters need to be skilled at navigating cultural contexts in addition to linguistic nuances in order to ensure accurate and contextually relevant communication. The interpreters' dedication to maintaining cultural authenticity within their respective languages is demonstrated by the examples given, which range from honoring elders in community meetings to communicating familial relationships and hierarchical structures.

Published: February 2024

This paper titled Hegelian Dialectic Model of Change: Catalyst for Religious Change in Nigeria submitted that religious change in Nigeria is real and there are several examples of change in persons and societies made possible by religion. These changes are not limited to one religion but several religions because Nigeria is a multi-religious nation. It is argued in this paper that among the several models of change that are available; the Hegelian model is more suitable and ideal for religious change in Nigeria. The paper explored in detail what Religious change entails and as well as indicators of change. Similarly, the paper explained what is meant by Hegelian dialectic model of change and reasons for considering it as ideal model for religious change in Nigeria. The paper advance ways of utilising Hegelian dialectic model of change without constituting threat to peace and harmony in Nigeria. The paper is theoretical in nature and the method adopted in writing the paper is the historical survey method. Needful recommendations are given in the paper on strengthening religious change without violence and assault.

Purpose: Conventional topical capsaicin creams are often unavailable and unaffordable to the larger patient populations in developing countries. There is a need to formulate cost-effective alternatives using locally available polymers as cream base. This study aimed to formulate oil-in-water Grewia mollis mucilage-hydroxypropyl methylcellulose (GMM-HPMC) based capsaicin creams from locally available capsicum fruits and evaluate their quality attributes. Methods: Capsaicin was quantified from acetone extracts of Capsicum fruits (C. frutescens, C. pubescens and C. chinense) using high performance liquid chromatography (HPLC). Extract of C. chinense which had higher capsaicin content was used to formulate six different cream types with varied concentrations of GMM and/or HPMC as polymeric base. The creams were assessed for their organoleptic properties, pH, specific gravity, conductivity, viscosity, spreadability, oil globule size, microbial load and stability profiles using standard methods and protocols. Results: The FTIR spectroscopic analysis confirmed the presence of capsaicin in all the Capsicum fruit extracts; HPLC quantification of each of the fruit extracts indicated the presence of both capsaicin; C. chinense: (36153 ppm) > C. frutescens: (7860 ppm) > C. pubescens: (4549 ppm) and dihydrocapsaicin; C. chinense (11044 ppm) > C. frutescens (6920 ppm) > C. pubescens (2828 ppm) as constituents. Formulated o/w creams were light to deep brick red in colour, with pH (6.11-6.44); specific gravity (1.00-1.03); electrical conductivity (292-1958 µS/cm); viscosity (2810-9190 mPas); spreadability (4.0-5.5 cm) and globule size (13 ± 8 µm to 91 ± 20 µm). The creams had satisfactory microbial load profiles and remained stable at 25 ± 2 °C but had varying degrees of stability at 40 ± 2 °C storage temperatures. The optimized formulations of the creams (FB, FE and FF) contained GMM as the mono polymeric, GMM10:HPMC10 and GMM15:HPMC10 as their co-polymeric base systems, respectively. Conclusion: This study has shown the suitability of Grewia mollis mucilage singly used or in combination with hydroxypropyl methylcellulose as co-polymeric cream base. Formulated creams had desirable physicochemical properties and they may find better patient acceptance when compared with imported brands as a result of their potential low cost.
