Geometric Optimization of the Five-Point Double-Toggle System for the Clamping Unit of an Injection Molding Machine with the Response Surface Method
Authors: Ho Thien Bao , Nguyen Huu Loc
Published: December 2024

Injection molding is one of the most used processes for the manufacture of plastic products with high-volume capacity. The five-point double toggle mechanism is frequently employed in the clamping unit to augment the force generated by a linear actuator, thereby achieving the requisite clamping force. This is a crucial aspect that determines the productivity and quality of the finished product in the injection molding process. Nevertheless, the geometrical synthesis of this type of mechanism has not been sufficiently addressed with regard to its integration into the mold design and the opening/closing stroke. This paper presents a novel approach for analyzing and evaluating the impact of parameters pertaining to mechanism posture on its force amplification, employing the Taguchi method. The relationship between force amplification ratio and the most influential parameters is simplified with the Face-Centered Central Composite Design (FCCCD) method, thereby allowing the optimal posture of the mechanism at the mold-closing stage to be determined. With these optimal parameters, once the mold height and desired opening/closing stroke have been selected, the dimensions of the links in the mechanism can be calculated. The results demonstrate that there are numerous combinations of these parameters that can yield a high force amplification ratio, thus providing the designer with a range of options for the design of a clamping unit. The proposed method can be employed at the initial stage of the design process to obtain a preliminary design, thus preparing for the dynamic analysis or further optimization problems of the mechanism.

Published: December 2024

Introduction. Numerous studies have demonstrated that patients infected with
hepatitis C virus have a higher prevalence of steatosis than those with other
hepatotropic viruses. Our objective is to evaluate the prevalence and predictive factors
of steatosis in patients infected with the hepatitis C virus. Patients and methods. The
files of patients followed at the internal medicine and infectious diseases department
of Barika for chronic hepatitis C were collected for this retrospective study. Patients
who did not undergo a liver biopsy (PBH) were not included. The diagnosis of steatosis
was made by the pathological study. Epidemiological, virological and histological
parameters were evaluated. To study the risk factors for steatosis, a univariate and
multivariate analysis was carried out using logistic regression. Results. 78 patients
had PBH. These are 59 (75.6%) women and 19 (24.4%) men. The average age was
55 years (32 - 72). The prevalence of fatty liver is 37.2%. The statistical analysis did
not demonstrate a significant association between steatosis and female sex (P at
0.561), cytolysis (P at 0.753), fibrosis (P at 0.063), viral load (P at 0.669), the genotype
(P at 0.510), alpha-fetoprotein (P at 0.401), dyslipidemia (P at 0.722). On the other
hand, the presence of diabetes (P at 0.017), severe fibrosis (P at 0.018) and
dysthyroidism (P at 0.049) significantly increases the risk of having steatosis.
Conclusion. According to our series, it appears that steatosis is common in patients
with chronic hepatitis C. Diabetes, severe fibrosis and dysthyroidism were the only
predictive factors for steatosis.

Published: December 2024

Introduction: It is well known that both normal pregnancy and pregnancy-induced
hypertension are associated with frequent fluctuations in blood uric acid (UA) levels.
The purpose of this study was to measure the serum uric acid levels of healthy
pregnant Sudanese women and to correlate these levels with blood pressure and
gestational age. Material and Methods: this is a cross-sectional hospital-based study
enrolled 50 healthy pregnant women from the prenatal care clinic of the Khartoum
Police Hospital using a convenient non-probability sampling technique. Standard
methods are used to measure serum uric acid and blood pressure. To assess the
relation between various variables, ANOVA test and correlation analysis were applied.
A P value of less than 0.05 considered statistically significant. Results: The
participant’s age ranged from 19 to 37 years old, with a mean of 27.7±4.3 years. The
range of uric acid levels was 1.4 to 7.1 mg/dL, with a mean of 2.6 ± 1 mg/dL. The blood
pressure was 110 ± 4 mmHg at the systolic level and 77.6 ± 4.3 mmHg at the diastolic
level. The study discovered that there was a significant correlation (p-value <0.0001)
between gestational age and serum uric acid level. However, the correlation with the
blood pressure was insignificant (p-value= 0.62 and 0.06 for systolic and diastolic
blood pressure, respectively). Conclusion: the study findings show that serum uric
acid levels are useful clinical tool, especially when assessing pregnant ladies beyond
20 weeks of pregnancy.

Published: December 2024

Introduction: The medication process consists of a number of steps in which
medication errors (ME) can occur. The aim of our work is to estimate the rate and
characterize ME. Materials and methods: A retrospective, descriptive study was
carried out in the compounding pharmacy of the Mother and Child Laboratory from 1
January 2021 to 31 December 2023. ME were collected from all patient prescriptions
requesting dose reductions received at the compounding pharmacy. Inclusion criteria
were all prescriptions received at the compounding pharmacy. Data were collected
using a specific ME sheet and the register of dose reduction requests. Microsoft Office
Excel 2019 was used to collect, organize and process the data. Results: During the
study, 616 cases (8.06%) of ME were collected out of 7640 requests received. They
mainly concerned the public sector, 543 cases (88.14%). General practitioners and
specialists were most involved, with 297 (48.21%) and 264 cases (42.85%)
respectively. ME is potential and preventable in all cases and occurred only at the
prescribing stage. They were mainly due to omission of duration of treatment in 201
cases (32.63%), frequency of administration and duration of treatment in 169 cases
(27.43%), and dosage errors in 107 cases (17.37%). Cardiology was the most
incriminated class with 344 cases (55.84%). The sex ratio was 1.24. Children were
most affected with 574 cases (93.18%). Conclusion: To avoid this type of error,
improving medical prescribing is crucial based on strengthening the training of doctors
on the rules of prescribing, especially in the paediatric population, as well as the
implementation of recommendations on the prescribing procedure within the hospital
wards, but also the improvement of communication between health professionals,
which must be taken into account.
Biomethane Production Through Performance Enhancement of
Anaerobic Digestion and Sludge Dewatering Processes in a
Wastewater Treatment Plant
Authors: Kanti Sen Tushar
Published: December 2024

Sewage sludge management poses a persistent challenge due to increasing volumes and stringent environmental regulations. Current municipal
wastewater treatment technologies are energy intensive, produce large quantities of residuals and fail to recover the potential resources available
in wastewater. Anaerobic digestion (AD) is widely recognized for its cost-effective stabilization, high organic matter removal, and biogas
production potential. However, the hydrolysis phase remains a bottleneck in AD, limiting methane yield. Furthermore, its application for low
strength municipal wastewater is limited. To address such challenges, the effects of combined microwave-ultrasonic and combined microwaveoxidative pre-treatment of thickened excess activated sludge and mixed sludge on the performance enhancement of conventional mesophilic
digester and on two-stage digesters are presented in this study. Microwave-ultrasonic pretreatment was optimized for enhanced cell disruption,
while microwave oxidation pretreatment incorporated hydrogen peroxide to generate reactive oxygen species for accelerated organic
solubilization. Experimental setups included single- and two-stage anaerobic digesters operated under mesophilic and thermophilic conditions.
Results demonstrated that combined microwave-ultrasonic pretreatment improved cumulative methane production by 18% and total solids
reduction by 31%, compared to microwave-only pretreatment. Microwave oxidation pretreatment with 1% H₂O₂ achieved 40% volatile solids
solubilization, significantly enhancing methane yield and sludge dewaterability. The two-stage AD process further improved performance,
achieving 76.4 mL/g TCOD methane yield and 58% methane content in biogas, outperforming single-stage systems. Findings indicate that hybrid
pretreatments synergistically enhance hydrolys

Восстановление коронального магнитного поля при помощи ограниченной оптимизации по данным SDO/HMI
Authors: М.Х. Джафарпур , С. Фатхолазаде , С. Насири
Published: December 2024

Хорошо известно, что динамика солнечной короны определяется магнитным полем. С другой стороны, измерить величину и определить структуру коронального магнитного поля невозможно из-за теплового уширения. По этой причине поле в короне может быть реконструировано с использованием данных, полученных с помощью магни- тограммы и физики бессиловых полей. Здесь мы предлагаем метод ограниченной оптимизации с использованием векторного множителя Лагранжа и сравниваем результаты с результатами существующих моделей. Численный ана- лиз нашей модели был проведен с помощью наблюдательной векторной магнитограммы, полученной с помощью изображений SDO/HMI. Мы приходим к выводу, что 1) лагранжиан в настоящей модели сходится немного быстрее, чем в моделях сравнения. 2) Поведение магнитной свободной энергии в процессе оптимизации согласуется с поведени- ем в предыдущих исследованиях. 3) Разработана модель для реальной магнитограммы. Вычислены такие величины, как содержание магнитной энергии, текущий взвешенный угол между вектором плотности тока и магнитным полем и относительные ошибки потока.

It is well known that the dynamics of the solar corona is governed by the magnetic field. On the other hand due to the thermal broadening it is not possible to measure the magnitude and determine the structure of the coronal magnetic field. For this reason, the field in the corona may be reconstructed using the data obtained by the magnetogram and the physics of force-free fields. Here we propose a method of constrained optimization using the vector Lagrange multiplier and compare the results with those of ever present models. The numerical analysis of the our model was conducted through an observational vector magnetogram obtained by SDO/HM I images. We conclude that i) the Lagrangian in the present model converges slightly faster than that of comparison models. ii) the behavior of the magnetic free energy during the optimization is compatible with those of the previous studies, iii) the model is worked out for a real magnetogram and the corresponding quantities such as magnetic energy content, the current weighted angle between the current density vector and magnetic field, and the fractional flux errors are computed.
К вопросу о существовании кометного семейства Урана
Authors: В.С. Усанин
Published: December 2024

Ранее считалось общепризнанным деление комет в зависимости от их афелийных расстояний на семейства Юпи- тера, Сатурна, Урана и Нептуна. Современная классификация оставляет только семейство Юпитера, а семейства Сатурна, Урана и Нептуна заменены галлеевским типом. Переход от старой классификации к новой до сих пор вы- зывает критику. В качестве одной из характеристик динамической связи комет с планетами предлагался критерий Радзиевского-Тиссерана, который имеет смысл большой полуоси орбиты возмущающей планеты. В данной статье, продолжающей предыдущую работу по семейству Сатурна, критерий Радзиевского-Тиссерана применен к кометам Кроммелина (27P), Стефана-Отерма (38P) и Темпеля-Тутля (55P) для проверки гипотезы об их принадлежности к семейству Урана. Ни одно значение критерия, вычисленное с учетом различных факторов, не лежит между боль- шими полуосями орбит Сатурна и Нептуна. Таким образом, динамической связи этих комет с Ураном не выявлено. Подтверждается современная классификация комет.

Earlier, the division of comets depending on their aphelion distances into the planetary families of Jupiter, Saturn, Uranus and Neptune was regarded as undoubted. The modern classification system retains only the Jupiter family, and the families of Saturn, Uranus and Neptune are replaced by the Halley type. The transition from the old classification system to the new one still raises criticism. The Radzievskij-Tisserand criterion, which fits the orbital semimajor axis of the perturbing planet, was proposed as a measure of the dynamical relation of comets to planets. In the present paper, continuing the previous work on the Saturn family, the Radzievskij-Tisserand criterion is applied to comets 27P/Crommelin, 38P/Stephan-Oterma, and 55P/Tempel-Tuttle for the evaluation of the hypothesis that they belong to the Uranus family. No one value of the criterion calculated considering different factors lies between the Saturn and Neptune’s orbital semimajor axes. So, no dynamical relation of these comets to Uranus is revealed. The modern comet classification system seems to be right.

Published: December 2024

Статья посвящена модернизации метеорного радара на базе системы SKiYMET в Казанском федеральном универ- ситете. Целью модернизации является повышение точности радиолокационных наблюдений за метеорами. В ходе модернизации количество антенн увеличилось с 5 до 12, а размеры измерительных баз были расширены до 220 м на 150 м. Эти изменения значительно улучшили точность измерений угловых координат, достигая значений не хуже 0.3 градуса. Также представлены статистические данные мониторинга, проведенного в 2023 г., по которым количество зарегистрированных метеоров с оценкой скорости метеора варьировалось от 15000 до 40000 в сутки. На основе анализа выявленных проблем и статистических данных предложены направления для дальнейшего развития радиолокационного метода наблюдений за метеорами в Казанском федеральном университете. Для повышения точ- ности наблюдений и расширения возможностей метеорного комплекса по регистрации метеорных следов и изучению притока метеорного вещества предлагается увеличить длину измерительных баз до 400 м на 200 м, и также устано- вить дополнительные антенны и приемные комплексы, оснащенные фазовыми интерферометрами, размещенными с значительным пространственным разносом, а также организовать совместные наблюдения метеорных явлений.

This paper focuses on the modernization of the meteor radar system based on SKiYMET at Kazan Federal University. The goal of this modernization is to enhance the accuracy of radar observations of meteors. As part of the upgrade, the number of antennas was increased from 5 to 12, and the measurement baseline was expanded to 220 meters by 150 meters. These enhancements significantly improved the precision of angular coordinate measurements, achieving accuracies of 0.3 degrees or better. Additionally, the article presents monitoring statistics from 2023, which indicate that the number of recorded meteors with velocity estimates varied between 15,000 and 40,000 per day. Through a detailed analysis of the encountered challenges and statistical data, several directions for the further development of radar meteor observation methods at Kazan Federal University are proposed. To further improve observational accuracy and expand the meteor radar system’s capabilities for detecting meteor trails and studying the influx of meteoric matter, it is proposed to increase the measurement baseline to 400 meters by 200 meters. This also includes the installation of additional antennas and receiving systems equipped with phase interferometers positioned with significant spatial separation, as well as the organization of joint observations of meteor phenomena.

Published: December 2024

The Coronavirus disease 2019 (COVID-19) pandemic heavily affected healthcare services and medication supply. Literatures showed that the consumption of antibiotics was significantly increased during the pandemic especially in COVID-19 hospitals, however, little is known about the collateral impact of the pandemic in non-COVID-19 healthcare settings, such as Hospital Queen Elizabeth II (HQEII) based in Malaysia. This study aimed to compare the prevalence of antibiotic consumption before (2018 & 2019) and during (2020 & 2021) the pandemic, and to explore its impact on antibiotic-acquired cost and bacterial resistance. This is a descriptive observational study where the antibiotic consumption from 1st January 2018 to 31st December 2021 in HQEII was reviewed. The antibiotics selected were Meropenem, Vancomycin, Piperacillin-tazobactam, Ceftazidime and Ceftriaxone. The antibiotic consumption, antibiotic-acquired cost and cases of multidrug resistant organism (MRO) before (2018 & 2019) and during (2020 & 2021) the COVID-19 pandemic were compared, with combined 2 years data for comparison. The overall consumption of the selected antibiotics significantly increased by 45.2% (34.8 vs 50.5, p<0.001) during the COVID-19 pandemic. Intensive care unit had the highest increase in antibiotic consumption (+114.3%, p<0.001). There was a raising trend for the use of Vancomycin, Meropenem, Ceftazidime and Piperacillin-Tazobactam (p<0.005). All these contributed to a significant increase in antibiotic-acquired cost by 64.4% during the COVID-19 pandemic (RM909,898.80 vs RM1,486,791.20, p<0.001). Notably, cases of multidrug resistant organisms also increased, especially MRO Acinetobacter (+197%) and Carbapenem-resistant Enterobacterales (+92%). High antibiotic consumption, antibiotic-acquired cost and MRO cases were observed in non-COVID-19 healthcare setting during the pandemic, but the factors contributing to the surge were not explored in this study.

Bobblehead Syndrome (BHS) is a rare neurological condition characterized by rhythmic and involuntary head movements, resembling a bobbing motion. This systematic review aims to consolidate current knowledge on the etiology, clinical presentation, diagnostic methods, and treatment options for BHS. A comprehensive search of peer-reviewed articles from medical databases was conducted, focusing on case reports, clinical studies, and reviews published over the past three decades. Findings indicate that BHS is frequently associated with third ventricular cysts, particularly colloid cysts, or hydrocephalus. Diagnostic imaging, such as magnetic resonance imaging (MRI) and computed tomography (CT), plays a crucial role in identifying underlying anatomical abnormalities. Treatment often involves surgical intervention, including ventriculoperitoneal shunting or endoscopic cyst fenestration, which significantly reduces symptoms in most cases. Despite advancements in diagnostic and therapeutic modalities, the rarity of BHS poses challenges in early recognition and management. This review underscores the need for increased awareness and further research to optimize outcomes for affected individuals.

Authors: Wahyuningtyas Tiara , Nugraheni Nuniek , Widajanti Novira , Haryono Yudha
Published: December 2024

Background: Low Back Pain (LBP) is a symptom characterized by pain in the lower back that may radiate to the right or left leg. LBP frequently occurs in individuals who engage in prolonged standing or sitting activities or lift heavy objects with improper posture. Studies suggest that LBP has a negative correlation with Serious Mental Illness and a positive correlation with pelvic tilt, indicating that sarcopenia may be associated with LBP due to posterior pelvic tilt. Objective: This study aims to analyze the relationship profile between low back pain and sarcopenia. Method: This is an observational study with a cross-sectional design conducted within a specific population over a defined period. The study subjects were selected using a random sampling method, comprising individuals aged ≥60 years at the UPTD Griya Wreda Jambangan who met the study criteria. Interviews were conducted using questionnaires for elderly individuals experiencing low back pain. Result: The statistical test results on the significance and strength of the relationship between variables using the Spearman Correlation Coefficient (with a significance level of p < 0.05) yielded a value of <0.01. This indicates that the research hypothesis is proven, demonstrating a relationship between low back pain and sarcopenia.
High Platelet to Lymphocyte Ratio (PLR) Associated with High Q-Sofa in Multi-Trauma Patients at RSUP Prof Dr I.G.N.G Ngoerah Hospital Denpasar
Authors: Pradita I Gede Wahyu Dwi , Wiargitha I Ketut , Mahadewa Tjokorda Gde Bagus
Published: December 2024

Background: Trauma is one of the world’s major health problems; in 2013, 56.2 million patients were hospitalized, and globally, 8 million people died from trauma. Traumatic injury can cause changes in immune function, which can lead to the activation of proinflammatory cytokines known as SIRS. In addition to the immune response in addition to SIRS, platelets also play an important role in trauma; platelets play a key role in hemostasis. A simple clinical screening tool that performs very well in identifying adult patients with suspected infection is called qSOFA. Apart from that, a new score, namely PLR, was also found to be able to predict the severity of trauma more quickly. Therefore, PLR is thought to be able to predict the severity of a trauma that results in SIRS using qSOFA. Objective: To determine if the high PLR value is significantly related to the improvement of the qSOFA score in multi-trauma cases. Method: This type of study is a cross-sectional study. The subjects of this study totaled 45, which were divided based on the data of PLR value variables, namely ≤ 200 and > 200, and qSOFA score variables, namely ≥2 and <2. Results: The Spearman test conducted in the study obtained a value of p = 0.001. In addition, the correlation value between PLR and qSOFA variables was found to be 0.444 in the contingency coefficient test and 0.469 in the Spearman test. Conclusion: Both variables show a significant relationship between PLR and qSOFA, so they can be used to assess each variable. However, the correlation shown by these two variables is quite low, so further research can be done to confirm this condition.
Total Protein Examination Using the Biuret Method
Authors: Sari Ni Putu Yunita Puspitra , Amril Aripa , Muttaminnah Muttaminnah
Published: December 2024

Protein is the main cellular component that makes up half of the weight of cells and has an important role in the structure and function of organisms.1Proteins are formed from one or more polypeptides which play a role in forming specific similarities (Figure 1).2Protein has a special function, namely building and maintaining body cells and tissues.2Total protein is all types of protein found in serum or plasma consisting of albumin, globulin and fibrinogen.3Protein analysis can be done in two ways, namely qualitatively and quantitatively. Qualitative protein analysis is by Xanthoprotein reaction, Hopkins-Cole reaction, Millon reaction, Nitropusicide reaction, and Sakaguchi reaction, while quantitative protein analysis is done using the Kjedahl method, formol titration method, Lowry method, visible spectrophotometry (Biuret) method, and UV spectrophotometry method.3 Examination of total protein levels in the blood is carried out using the biuret method which is seen from the color reaction between the alkaline copper reagent and the CO-NH peptide chain which produces a purple color. 4 This method is based on the number of fixed CO-NH chains per unit mass of protein. The working principle of this method is the color equation with copper ions, where the protein in the serum reacts with copper ions in an alkaline (basic) environment, thus forming a purple complex compound whose color intensity is proportional to the total protein content in the blood. 4,5 The intensity of the purple color indicates the total protein content in the sample so that it can be assessed photometrically by measuring its absorbance using a spectrophotometer at a light wavelength of 546 nm. The advantages of the biuret method compared to other methods in measuring total protein levels are that the examination is not affected by temperature, produces different colors in different proteins, has good examination repeatability, and high accuracy, while the disadvantages of the biuret method are low sensitivity and many interfering factors, EDTA samples can interfere with the interpretation of the results.

Este trabalho examina o racismo estrutural no mercado de trabalho, focando nos desafios enfrentados por mulheres negras para alcançar cargos de gestão em empresas privadas. O estudo explora como práticas institucionais sustentam desigualdades raciais e revela os obstáculos, como estereótipos e discriminação, que dificultam a ascensão dessas mulheres, mesmo quando qualificadas. Destaca-se a persistente sub-representação de mulheres negras em cargos de liderança e as diferenças salariais em relação a mulheres brancas. A pesquisa enfatiza a importância de políticas de inclusão, como mentorias e programas de diversidade, para criar um ambiente corporativo mais equitativo. Através de análises quantitativas e qualitativas, evidencia-se que barreiras invisíveis, como preconceitos estruturais, limitam o crescimento profissional dessas mulheres. Recomendações são feitas para combater o racismo estrutural, incluindo recrutamento inclusivo, treinamentos sobre diversidade e revisão de políticas internas para assegurar igualdade de oportunidades. A representatividade de mulheres negras em cargos de gestão é vista como crucial para inspirar mudanças nas estruturas corporativas. O estudo conclui que o empoderamento dessas mulheres depende do compromisso de toda a sociedade para promover um mercado de trabalho mais justo e acolhedor para todos.
O USO DO AGREGADO TRIÓXIDO MINERAL (MTA) NO TRATAMENTO ENDODÔNTICO EM DENTES PERMANTES COM RIZOGÊNESE INCOMPLETA
Authors: Araújo Eduarda Moreira , Machado Yuri Freitas
Published: December 2024

O objetivo deste estudo foi analisar as dificuldades enfrentadas no tratamento endodôntico de dentes permanentes com rizogênese incompleta, caracterizados por ápices radiculares abertos e grandes forames apicais. O estudo também investigou as estratégias de apicificação, com ênfase nos materiais utilizados, como o Hidróxido de Cálcio (HC) e o Agregado de Trióxido Mineral (MTA), para promover a formação de uma barreira mineralizada, favorecendo a maturação da raiz e o fechamento apical adequado. A pesquisa revisou o uso do Hidróxido de Cálcio, que tem sido empregado desde a década de 1960 para induzir a formação de barreira mineralizada na região apical. O estudo também explorou a utilização do MTA, um material biocompatível com propriedades antimicrobianas e de indução de dentina, que facilita o fechamento apical e a prevenção de infecções persistentes. Os resultados indicaram que, embora o Hidróxido de Cálcio seja eficaz, o sucesso do tratamento depende de uma técnica adequada e da resposta biológica do dente. O MTA, por sua vez, tem mostrado excelentes resultados devido às suas características biocompatíveis e de indução de formação de dentina, além de promover o selamento do canal radicular de forma eficaz. O uso de soluções irrigantes adequadas também é essencial para garantir a biocompatibilidade e a eficiência do tratamento. Conclui-se que o tratamento endodôntico de dentes com rizogênese incompleta exige estratégias específicas, como a apicificação com Hidróxido de Cálcio ou MTA, para promover a formação de barreiras apicais e a maturação radicular. A monitorização radiográfica constante e o ajuste das técnicas de acordo com a resposta biológica do dente são fundamentais para o sucesso a longo prazo. O estudo destaca a importância de escolher materiais e técnicas adequados para preservar a saúde pulpar e alcançar um prognóstico favorável para o dente.

The paper "Challenges of Social Integration of Ukrainian refugee women and their children" explores the difficulties these vulnerable groups face in adapting to the new living conditions in Romania. Introduction: The research focuses on the social integration of Ukrainian refugee women and their children, emphasizing the impact of the war in Ukraine, which triggered massive migration to neighboring countries. Refugee women and children face challenges related to health, education, and social integration, their context being complex and full of uncertainties. Objectives and Methodology: The study aims to assess the social and professional integration of Ukrainian refugee women, identifying the determinants of the quality of life and the barriers encountered in the integration process. The research was carried out by applying a structured questionnaire (Quality of Life Inventory - QOLI) and an interview grid, addressed to a sample of 32 Ukrainian women aged between 18 and 65, located in care centers in Tulcea county. The collected data were analyzed using SPSS software. Results: The results revealed correlations between job satisfaction and quality of life, as well as between financial resources and the level of social integration. The main barriers to integration have been identified, including economic difficulties, language barriers, and cultural adaptation. The research also showed that the level of integration of children in the educational system is influenced by the support provided by the community and schools. Conclusions: The paper highlights the need for tailored support policies to facilitate the social integration of Ukrainian refugees. The effective integration and improvement of the quality of life of this vulnerable group depend on a multidimensional approach, which includes economic, social, and psychological support. The research contributes to a better understanding of the challenges faced by refugee women and provides recommendations for improving integration processes.
Reproductive Justice & Women’s Human Rights
Authors:   Distinguished Professor Emerita University of California, Santa Cruz Feminist Studies Department, Aptheker Bettina
Published: December 2024

This paper argues that women must have as much sovereignty over their own bodies, and decisions effecting their health and well-being as men have over theirs. Conditions for reproductive justice are foundational for women’s human rights. Reproductive justice includes access to abortion, and to pre- and post-natal care, decisions regarding the spacing of pregnancies and whether or not to have children, reductions in infant and maternal mortality, and appropriate conditions for the successful and healthful care and raising of children. From this point of view reproductive justice and women’s human rights are intertwined with the abolition of colonialism, neo-colonialism, racism, poverty, and war, and a recognition of women’s full humanity.
The Holographic Principle as a Resolution of the Black Hole Information Paradox: Is an omniscient perspective possible based on a Holographic Model of the event horizon of the Universe?

We seek to examine the ontological aspects of the resolution of the black hole information paradox. Several concepts which are now central to our understanding of quantum mechanics arose from our resolution to this paradox, and these concepts point to the conservation of all information, even on a quantum level. If quantum information is conserved and can never be erased or destroyed, then this indicates that all information is at least theoretically, ultimately retrievable and knowable from the event horizon of the universe. Ontologically, this supports the contention that a repository of all information in the universe must therefore exist. Herein, we trace the steps in this contention and conclude with the argument that our understanding of the universe points to the existence of an omniscient entity.
