The Frontlines and Margins: Gendered Care and Covid-19 in the Indian Media
Authors: Raman Usha , Kasturi Sumana
Published: February 2023

Among the many stories that emerged out of India during the pandemic, one was somewhat buried under the media discourse around the migrant crisis, lockdown regulations, and economic fallout. This was the story of striking accredited social health activist workers asking for fair wages, improved benefits, and better working conditions. The Covid-19 crisis highlighted the poor health infrastructure and the precarious, and often, stigmatized nature of frontline work, managed at the community level by paramedical workers, a significant proportion of whom are women. There has been considerable attention paid by feminist groups as well as health-related civil society organizations on the gender-based inequities that have emerged during the pandemic, particularly in relation to care work. This study explores how care work performed by the accredited social health activists was framed in the mainstream media, through an examination of articles in three selected English daily newspapers over one year of the pandemic. Drawing on theoretical work deriving from similar health crises in other regions of the world, we explore how the public health infrastructure depends on the invisible care-giving labor of women in official and unofficial capacities to respond to the situation. The systemic reliance on women’s unpaid or ill-paid labor at the grassroots level is belied by the fact that women’s concerns and contributions are rarely visible in issues of policy and public administration. Our study found that this invisibility extended to media coverage as well. Our analysis offers a “political economy of caregiving” that reiterates the need for women’s work to be recognized at all levels of functioning.
Journalism in Democracy: A Discourse Analysis of Twitter Posts on the Ferrerasgate Scandal
Authors: Reguero-Sanz Itziar , Berdón-Prieto Pablo , Herrero-Izquierdo Jacobo
Published: February 2023

This research analyses the discourse on Twitter surrounding the “Ferrerasgate” scandal involving the Spanish journalist Antonio García Ferreras, director and host of the television show Al Rojo Vivo (La Sexta, Spanish TV channel). It examines the main object of criticism, the tone of the discourse, the argumentation made by users, as well as the existence of hate in their rhetoric. The tweets included in the study’s sample (N = 2,846), posted between 5 and 15 July 2022 and extracted on 16 July 2022, were examined in two complementary phases. The first entailed a quantitative content analysis of the messages and the second analysed whether hate speech was found in the sample as a whole. The Sketch Engine tool was used to determine whether “crypto hate speech” existed in the sample as a whole, and to whom it was targeted. The results reveal that “Ferrerasgate” sparked a debate that spilt over into journalism across the board, calling into question the media’s role in a democracy. The most prominent arguments were the condemnation of misinformation, lack of independence, and absence of professionalism in the journalism sector. It should be noted that most of the messages were destructive in tone; hate was found in the tweets analysed, although these did not represent a high percentage in relation to the total sample.
High-Precision Characterization of Seismicity from the 2022 Hunga Tonga-Hunga Ha'apai Volcanic Eruption

Published: February 2023

The earthquake swarm accompanying the January 2022 Hunga Tonga-Hunga Ha'apai (HTHH) volcanic eruption includes a large number of posteruptive moderate-magnitude seismic events and presents a unique opportunity to use remote monitoring methods to characterize and compare seismic activity with other historical caldera-forming eruptions. We compute improved epicentroid locations, magnitudes, and regional moment tensors of seismic events from this earthquake swarm using regional to teleseismic surface-wave cross correlation and waveform modeling. Precise relative locations of 91 seismic events derived from 59,047 intermediate-period Rayleigh- and Love-wave cross-correlation measurements collapse into a small area surrounding the volcano and exhibit a southeastern time-dependent migration. Regional moment tensors and observed waveforms indicate that these events have a similar mechanism and exhibit a strong positive compensated linear vector dipole component. Precise relative magnitudes agree with regional moment tensor moment magnitude (Mw) estimates while also showing that event sizes and frequency increase during the days after the eruption followed by a period of several weeks of less frequent seismicity of a similar size. The combined information from visual observation and early geologic models indicate that the observed seismicity may be the result of a complex series of events that occurred after the explosive eruption on 15 January, possibly involving rapid resupply of the magma chamber shortly after the eruption and additional faulting and instability in the following weeks. In addition, we identify and characterize an Mw 4.5 event five days before the paroxysmal explosion on 15 January, indicating that additional seismic events preceding the main eruption could have been identified with improved local monitoring. Our analysis of the HTHH eruption sequence demonstrates the value of potentially utilizing teleseismic surface-wave cross correlation and waveform modeling methods to assist in the detailed analysis of remote volcanic eruption sequences.
Point-Source Decay of Ground-Motion Amplitudes at <10 km
Authors: Atkinson Gail M. , Viegas Gisela
Published: February 2023

The amplitudes and decay rate of ground motions from small to moderate earthquakes are important to the assessment of induced seismicity hazards and useful as input components to finite-fault models of larger events. The decay rate of mining events (M < 3) recorded on hard rock is consistent with a geometric spreading rate of R−1.3, with no apparent saturation effects in the hypocentral distance range from 0.15 to 8 km. Response spectral acceleration often exceeds 1000  cm/s2 at high frequencies (>10 Hz) for events of M < 3 at <0.5 km. Underground motions in rock are less than those on surface at low frequencies, and greater at high frequencies, in a way that is explained by the product of free surface amplification and near-surface attenuation (kappa) effects.
Impact of Group Tele-exercise on Physical Activity Determinants and Behavior in Individuals with Spinal Cord Injury
Authors:   , Baehr Laura , Finley Margaret
Published: February 2023

Physical activity is crucial for health maintenance of individuals with spinal cord injury (SCI), yet 50% of this population lead sedentary lives. Several modifiable challenges to physical activity behavior exist including inaccessible environments, negative body-self relationship, minimized exercise identity and knowledge. Digital health technologies, such as internet-based tele services, offer a potential platform to address these obstacles, but SCI-specific methods and evidence are needed. We developed an 8-week synchronous group tele-exercise program for individuals with SCI grounded by Social Cognitive Theory (SCT) to address societal barriers to exercise to influence individual determinants of physical activity behavior. Our feasibility study with 11 participants demonstrated 100% retention, high class attendance, and participant reports of increased exercise knowledge, confidence, and motivation. Given strong feasibility, the next step to evaluate the impact of this program was to assess the effects of group tele-exercise participation on physical activity determinants and behavior as identified by SCT in individuals with SCI. This clinically registered non-randomized trial [NCT05360719] used convergent mixed methodology. The single-group repeated measures design allowed for quantitative and qualitative assessment of primary measures at pre-program and following intervention completion (post-program), with an 8-week retention follow-up of quantitative assessments only. We hypothesized that exercise self-efficacy, exercise outcome measures, and moderative-vigorous leisure time physical activity (MVPA) behavior would significantly improve at post-program and benefits would be retained at retention. Congruence between numeric and thematic findings was present for exercise self-efficacy and self-evaluative exercise outcome expectations. Improved exercise self-efficacy was influenced by exercise knowledge gained during program participation. Increased expectations of internal exercise outcomes, such as influence on psychological state and overall mood, occurred following program participation. Themes on program-specific elements that facilitated increased intentional movement throughout daily life including portability and sustainability were not reflected in MVPA numeric assessment. This study is a critical first step toward systematically evaluating the effect of group tele-exercise on physical activity behavior for individuals with SCI and provides an important framework for the future evaluation of this program in randomized controlled trials. These findings demonstrate that this group tele-exercise program can positively influence critical SCT-driven personal determinants of physical activity behavior and has the potential to facilitate increased physical activity behavior.
High Conjugation Efficiency CdPbS Near-infrared, Direct-Staining Molecular Probe Toward Intraoperative Breast Cancer Margin Assessment
Authors:   , Jednorski Alexandra , Shih Wan Y , Shih Wei-Heng
Published: February 2023

Breast cancer makes up a large fraction of newly diagnosed cancer cases in the US. About 42% of breast cancer patients choose to undergo a lumpectomy or breast-conserving surgery (BCS) as opposed to mastectomy. Around 25% of the time, a re-excision surgery must be performed to remove more breast tissue as breast cancer margins were found to be positive post-BCS. There is a need for a rapid and specific intraoperative breast cancer margin assessment technique, so margins can be assessed during surgery reducing the incidence of re-excision surgeries. A molecular probe consisting of a near-infrared (NIR) emitting aqueous quantum dot (AQD) conjugated to a cancer-specific antigen antibody (Ab) was developed for direct immunofluorescence staining of breast cancer tissues. Quantum dots (QDs) are semiconducting nanocrystals. They possess superior optical qualities to traditional organic dye fluorophores used in immunofluorescence imaging including increased photostability and tunable excitation and emission wavelengths. Specifically, CdPbS AQDs were applied to the molecular probe design as they emit NIR light that is well-separated from any tissue autofluorescence. They have a facile aqueous synthesis without the need for phase transfer; however, they become unstable in biological conditions like neutral buffers. Therefore, before conjugation to the Ab, the AQD surface was modified by replacing its original capping-molecule with dihydrolipoic acid (DHLA). This method rendered a highly stable AQD ready for conjugation to Ab in a neutral environment. The molecular probe utilized polyethylene glycol (PEG) to act as a spacer between DHLA-replaced AQD and Ab. This allowed for a high conjugation efficiency with multiple AQDs bound per Ab, something not found in literature on direct staining. The molecular probe design was developed using cell lines before its application to human breast tissue slices. It had a repeatable signal-to-noise ratio of ~28. In formalin fixed paraffin embedded human breast tissues, it showed sensitivity and specificity of over 95% for the Tn antigen, specific to carcinomas. A professional pathologist deemed the tissue staining results promising. A more diverse set of breast tissue cases should be stained in the future for a greater understanding of the molecular probe's application to various breast pathologies before its application to freshly excised breast tissues. At that stage, a custom imaging setup can be utilized for macroscopic tissue imaging. The imaging system was tailored to the properties of the AQD fluorescence and evenly illuminates an area large enough for most tumor sizes. Overall, a high conjugation efficiency NIR molecular probe with multiple AQDs per Ab was designed for direct imaging of breast cancer tissues with promise for future applications in intraoperative imaging of fresh tissue specimens.

O padecemento dos animais, o mesmo que o dos nenos e nenas en tempos de guerra non sempre foi abordado con atención. Se as crianzas son invisibilizadas e sofren unha infancia aniquilada, maior esquecemento é o que envolve os animais, aínda que estes padecen as mesmas consecuencias cás persoas durante os períodos máis escuros da nosa historia. A través de narracións femininas en lingua galega preténdese mostrar a violencia exercida sobre os animais humanos e non humanos, sobre todo nas obras da memoria do franquismo, se ben se aludirá a outros conflitos e épocas.
A “mãe carinhosa”
Authors: Carneiro Rosamaria , Weidner Maluf Sonia
Published: February 2023

Este artigo se debruça sobre os desenhos da figura da mãe carinhosa na contemporaneidade. Para isso, analisamos as narrativas de duas gerações de mulheres de uma mesma família: a de mães (1940-1950) e a de suas filhas (1970-1980) depois que se tornaram mães. As conversas em profundidade com mulheres de diferentes regiões no Brasil e de classe social; às voltas com suas experiências de gestação, parto e maternagem, aconteceram entre 2020 e 2021. Diante da insistência da noção de carinho por elas propalada, reivindicada e também lamentada em campo, nos pareceu interessante investir em sua descrição a fim de apontar para sua pluralidade e porosidade. Nesse encalço, ao constatarmos que os contornos da mãe carinhosa são oferecidos por uma gama de discursos e de práticas postas para muito além do mundo privado e de uma lógica familista, sugerimos que sua produção se dá por “uma economia política das emoções”. Economia essa aliada aos projetos de Estado e ao neoliberalismo que dependem da figura materna para sua sustentação, ainda que de modos travestidos de amorosidade e renda psíquica. Constatou-se que as gramáticas emocionais que informam a figura materna nas últimas  quatro décadas são atravessadas no Brasil por raça/cor; classe social; gênero e geração, dando assim ideias plurais de raiva e de afeto, bem como de maternagens, aqui tomadas como ação, como verbo e não como uma instituição.
Análisis de Recursos Educativos Digitales centrados en el Cuerpo Humano desde la Perspectiva de Género en la Infancia
Authors: Vázquez Regueira Helga , Cacheiro González María Luz
Published: February 2023

El presente trabajo constituye un estudio de carácter descriptivo, con el que tomando como base la perspectiva de género, se han analizado diversos recursos educativos digitales, dirigidos al conocimiento del cuerpo humano y sus funciones para los niveles de Infantil y Primaria. Estos materiales han sido seleccionados a través de diversos repositorios y plataformas en red de acceso libre. Para ello, se ha elaborado una ficha de evaluación para identificar las características predominantes de los recursos que componían las unidades de estudio (n=78), basada en las propuestas de los estudios previos. Los resultados constatan que éstos fomentan las representaciones egocéntricas, occidentales, heterosexual, sin diversidad funcional, con un somatotipo atlético o delgado y sin genitales. Asimismo, se invisibilizan determinados grupos de edad, y el tratamiento de la reproducción y la sexualidad, lo que implica que no se tiene en cuenta lo establecido en los currículos educativos. Con este análisis pretendemos visibilizar las posibilidades de una adecuada selección de recursos educativos digitales para el tratamiento didáctico del Cuerpo Humano desde la Perspectiva de Género en la Infancia.

The neurotoxins rotenone and 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (МPTP) are used for modeling Parkinson's disease in animals (PD). They induce the mitochondrial respiratory chain dysfunction, which leads to the dopaminergic (DA) neuron degeneration. The advantage of the rotenone model consists in ability of rotenone to cause neurodegeneration showing symptoms and molecular biological characteristics similar to those of PD. Isatin (indoldione-2,3) is an endogenous regulator found in tissues and biological fluids of humans and animals. It exhibits a broad range of biological activity mediated by numerous isatin-binding proteins. In this work we have investigated behavioral reactions and profiles of brain isatin-binding proteins of rats with Parkinson's syndrome (PS) in comparison with the corresponding parameters of MPTP-induced Parkinsonism in mice. Systemic injection of rotenone caused severe PS comparable with the effect of MPTP injection. It was accompanied by significant body weight loss, death, oligokinesia, muscular rigidity, and postural instability of animals. In spite of the same pathogenic basis of PS caused by rotenone and MPTP, the molecular mechanisms of their action differ. In the case of rotenone-induced PS, the pool of isatin-binding proteins common of the control rats and the rats with PS (146) significantly exceeded the pool of the common proteins of control mice and mice with PS induced by MPTP, whether right after neurotoxin injection (27), or (all the more) in a week after the MPTP injection (14). The comparison of isatin-binding proteins specific of the animals with MPTP-induced PS and with the rotenone-induced PS (as compared with the control animals) revealed total absence of proteins common of these two models of PD. It is to be noted that both neurotoxins particularly affected the proteins participating in the signal transmission and enzyme activity regulation. The changes of the profile of isatin-binding proteins in response to the injection of rotenone suggest that the neuroprotector isatin could also influence positively in the case of the rotenone model of PD.

Published: February 2023

Human mycoses have become a threat to health world-wide. Unfortunately there are only a limited number of antimycotic drugs in use. In the present study, antifungal activity of earlier synthesized spiro-1,4-dihydropyridines (1,4-DHPs) was investigated. The antifungal activity of spiro-1,4-DHPs compounds were screened against Aspergillus flavus, A. fumigatus, and Candida albicans by using Disc Diffusion and Modified Microdilution method. Among six spiro-1,4-DHPs compounds tested all of them showed stronger antifungal activity possibly through inhibiting the synthesis of chitin in cell wall against A. flavus, A. fumigatus, and C. albicans as compared to fluconazole, a standard antifungal drug. The combination of compounds showed that the synthesized compounds had synergistic, additive effects as compared to currently used drugs as an antifungal agent. These results indicated that these designed compounds were potential chitin synthase inhibitors and had excellent antimycotic activity for the treatment of fungal infections.
Smart Doctor: pandemia de COVID-19 y compra de innovación en salud: fortalecimiento de las capacidades de los países de la región para la implementación de metodologías de compra pública de innovación
Authors: Lovera Viloria Victor Alfonzo , Sinde Cantorna Sandra
Published: February 2023

Una de las razones que suele justificar el uso de las políticas de innovación de demanda, en particular la compra pública, son los efectos que puede tener sobre el dinamismo del ecosistema emprendedor de una economía. En particular la compra pública de soluciones innovadoras puede activar la creatividad de las empresas tecnológicas emergentes (startups) y generar aprendizaje que les permita crecer y competir exitosamente en mercados globales. Sin embargo, a la fecha existe todavía poca documentación sobre si estos resultados son también observables en las startups de la región que desarrollan soluciones a los retos planteados por el sector público. Esta publicación detalla los aspectos más importantes del caso de Smart Doctor, una startup peruana que desarrollaba soluciones digitales de telemedicina inicialmente para el mercado de salud privada pero que aprovechó las oportunidades de la pandemia del COVID-2019 para ofrecer las soluciones digitales al Ministerio de Salud de Perú. Esto generó una dinámica de aprendizaje y perfeccionamiento de la solución desarrollada que le ha permitido a la empresa ganar experiencia y acceder a mercados internacionales. Este caso busca aportar a la discusión tanto académica como en los espacios de toma de decisión a nivel gubernamental sobre la compra pública de innovación (CPI) como herramienta de promoción de la innovación y de dinamización del ecosistema emprendedor de la región.
El “descubrimiento” de la geografía americana: la importancia de las Crónicas de Indias
Authors: Olcina Jorge
Published: February 2023

La ciencia geográfica ha encontrado en los textos literarios una fuente documental para entender elementos y procesos territoriales.  El conocimiento de la geografía iberoamericana encuentra en la literatura una fuente de estudio de gran importancia, por la calidad de las descripciones que contienen y la impronta sensorial que transmiten. Entre estos textos, las Crónicas de Indias, escritas tras el descubrimiento del nuevo continente, son documentos imprescindibles para el conocimiento del territorio americano, de sus rasgos físicos y del funcionamiento de las sociedades existentes. El trabajo estudia varias crónicas escritas entre los siglos XVI y XVII, para valorar su papel como fuente para el estudio de la geografía americana y para el impulso de las ciencias.
Agentes sociales, escalas y producción del espacio: elementos para una discusión
Authors: Corrêa Roberto Lobato
Published: February 2023

Discutimos, una vez más, el concepto de escala en Geografía, dando énfasis aquí a su relación con los agentes sociales y la producción del espacio. En el primer apartado retomamos diversas acepciones de la noción de escala y desarrollamos, particularmente, las escalas espacial y conceptual. La escala espacial constituye un rasgo fundamental de la acción humana y está relacionada a prácticas que se realizan en ámbitos espaciales más o menos amplios pero no disociados entre sí. La escala conceptual es considerada en una doble perspectiva: la red urbana y el espacio intraurbano. Aunque interdependientes, ambas perspectivas aluden a fenómenos, procesos y representaciones cartográficas diferentes. En el segundo apartado discutimos algunas relaciones entre agentes sociales, sus prácticas, su escalaridad y la producción del espacio, reconociendo que esos agentes están insertos en la temporalidad y espacialidad de cada formación socioespacial capitalista y que el Estado desempeña múltiples papeles con relación a la producción del espacio. Innumerables agentes sociales operan en ambas escalas conceptuales, es decir, desde la ciudad o parte de ésta hasta la red urbana, el país o el espacio global, como en el caso de las grandes corporaciones. Finalmente, se sugieren dos propuestas generales para investigación sobre esas relaciones: por un lado, el estudio de una determinada área, cuya producción resulta de las acciones de diversos agentes sociales en yuxtaposición, complementariedad y antagonismo y, por otro lado, el estudio de la acción de un agente social en su espacialidad multi-escalar.
Boosting the circularity of waste management: pretreated mature landfill leachate enhances the anaerobic digestion of market waste
Authors: Fazzino Filippo , Pedullà Altea , Calabrò Paolo S.
Published: February 2023

Adequate waste management is essential not only to ensure healthy living conditions but also to mitigate climate change. Accordingly, the research on developing strategies to boost the circularity of waste management systems is ongoing. In this context, two waste streams are concurrently managed to recover energy and materials in the present study. Specifically, real leachate collected from a full-scale mature landfill site was preliminarily treated through active filtration to remove inhibitory substances partially and then tested, at the laboratory scale, as a nutrient solution for semi-continuous anaerobic digestion of a carbonaceous substrate represented by market waste. The results demonstrate that, at an organic loading rate of 1.0 gVS∙L-1∙d-1, the process was impossible without using the nutrient solution, while the nitrogen present in the pretreated leachate could balance the carbon content of the market waste and provide the system with the necessary buffering capacity, ensuring process stability. The average methane yield (approximately 0.29 NL∙gVS-1) was satisfactory and consistent with the literature. Despite the increases in both the organic loading rate (up to 1.5 gVS∙L-1∙d-1) and volume of added pretreated leachate (up to 100% of the dilution medium), the process remained stable with a slightly lower methane yield of 0.21 NL∙gVS-1, thanks to nitrogen supplementation. The potential use of produced methane as a renewable energy source and residual digestate as fertilizer would close the loop of managing these waste streams.

Published: February 2023

Economic growth has recently been crowded out by life quality in the new development pattern. Unlike the income-based measurement of economic growth, the life quality measure has become a challenge because it is a multi-dimensional concept that relies on the subjective evaluation of the involved stakeholders in a particular context. The objective of this study was to investigate the model of quality of urban life in Ho Chi Minh City, Vietnam based on subjective indicators. The word clouds and grey analytical hierarchy process were employed to analyze the data from thirty in-depth interviews with experts in the field. The empirical model of quality of urban life in Ho Chi Minh City was found with three levels. The ranking results at the second level emphasized the high shares of health, employment, and income compared to self-esteem, socialization, and family happiness. The ranking results at the second level emphasized the high shares of health, employment, and income compared to self-esteem, socialization, and family happiness. Further investigation at the third level has confirmed the superiority of non-material components in the quality of urban life model in Ho Chi Minh City, Vietnam. The findings were critical in implying the policy concentration on non-material values enhancement to raise the quality level of urban life. It was a milestone in switching the focus from material to non-material factors in the life quality model in Vietnam.

Published: February 2023

Safety and security are the most significant factors in human life. Accordingly, achieving the required level of safety and security needs steps to keep an acceptable level and fully manage and support it with appropriate activities. Securing both domains requires implementing a risk management process that will be effective and have the desired results. The whole issue is closely related to the critical context, which is the source of essential information regarding the risk management process, and which is related to the environment, processes, and stakeholders. This paper deals with determining the first part of the context analysis – environmental analysis. Techniques (PESTLE and SWOT analysis) are proposed for optimal analysis in the paper, and the analysis is subsequently carried out on the example of air transport in Slovakia. The article provides a fundamental overview of environmental analysis and is suitable for further research.

Maternal mortality rates remain unacceptably high, especially in developing countries like Nigeria. Nigeria is responsible for about 20% of all global maternal deaths, with a Nigerian woman having a 1 in 18-lifetime risk of dying because of pregnancy or childbirth. Evidence-based strategies have been proposed, including family planning (FP), to reduce the incidence of maternal mortality, which is the only strategy that reduces the proportion of high-risk pregnancies and births and reduces exposure to the risk of maternal mortality. Despite these benefits, there is still a high unmet need for family planning services. The present study assesses the choices and availability of FP services in Lagos state health facilities, examines the challenges, barriers, and cultural restraints to modern contraception, and proffers solutions that will help increase FP uptake in the state. The study also presented supply-and-demand interventions that are most effective at increasing voluntary contraceptive uptake in Lagos state.

Aim: The use of social media, especially Instagram, has become widespread in the medical field. The aim of this study was to evaluate Achilles tendon surgery from patients' perspectives by examining public posts on Instagram.

Material and Methods: A retrospective analysis was made of the Instagram posts of patients with the hashtags #achillestendonsurgery and #achillestendonrepair between December 2018 and October 2021. In total, 234 posts (181 photographs, 53 videos) were evaluated and compared in terms of gender, sharing format (video, photo), sharing tone (negative, positive, neutral), content (activities of daily living, rehabilitation, cast/brace, hospital room, surgical site), country and popularity (the number of views for videos, the number of likes for photographs).

Results: Posts in video format and a positive tone, posts on the rehabilitation process, and posts about male patients were found to have higher numbers of likes and views than other posts. The content of the shares were respectively; activity of daily living 36.8%(n=86), physical therapy 29.9%(n=70), cast/brace 20.1%(n=47), surgical site 7.7%(n=18), and hospital room 5.6%(n=13). The media tone of the posts was 40.2%(n=94) positive, 6.4%(n=15) negative, and 53.4%(n=125) neutral.

Conclusions: Patients avoided making negative posts on their Instagram after Achilles tendon surgery, and often shared experiences of postoperative rehabilitation processes and daily living activities.

Aim: The aim of this study was to determine the effect of paternal age on miscarriage rates in couples undergoing in vitro fertilization/intracytoplasmic sperm injection treatment cycles.
Material and Methods: Patients were classified into two groups. The study group consisted of the patients whose pregnancy resulted in a miscarriage (n=73) and a control group in which the patients had a live singleton birth (n=256). Demographic characteristics, treatment indications, duration of infertility, menstruation day 3 follicle stimulating hormone, estradiol, luteinizing hormone, total antral follicle count, anti-Mullerian hormone levels and controlled ovarian stimulation parameters, day of trigger, estradiol and progesterone levels on the day of trigger, the total number of oocytes retrieved, the number of mature oocytes, the number and quality of the embryo, endometrial thickness on the day of trigger, oocyte pick up and embryo transfer, the distance of embryo-fundus and the day of embryo transfer were recorded.
Results: Totally 329 women were included in the present study. The number of patients with the diagnosis of unexplained infertility was statistically significantly higher in the study group than in the control group (p=0.020). Maternal age was found statistically significantly higher in the study group than in the control group (p=0.025). When maternal age increased by 1 unit, the risk of miscarriage increased by 8.7% and those with unexplained infertility had a 75.6% higher risk of miscarriage than those without unexplained infertility.
Conclusion: Paternal age was not associated with miscarriage whereas maternal age and unexplained infertility had a positive correlation with miscarriage rate.
Problemy wykładni międzynarodowych umów w sprawie unikania opodatkowania, sporządzonych w dwóch lub większej liczbie języków

Umowy międzynarodowe mogą być sporządzane w jednym, dwóch lub większej liczbie języków. Różne są przyczyny tego stanu rzeczy – od politycznych po czysto pragmatyczne. Wielojęzyczność traktatów dotyczy także umów w sprawie zapobiegania unikaniu opodatkowania. Artykuł poświęcony jest analizie problemów, jakie niesie z sobą wielojęzyczność traktatów w sprawach podatkowych oraz sposobom ich unikania bądź też rozwiązywania.
Zasady równomierności i ustawowości opodatkowania w Niemczech
Authors: Mirek Ireneusz
Published: February 2023

Zasady równomierności oraz ustawowości opodatkowania (ustawowego nakładania podatków) były w tradycji doktryny niemieckiej wyprowadzane z ustawowej definicji podatku w Ordynacji podatkowej. Współcześnie obie te zasady, zgodnie z orzecznictwem Federalnego Sądu Konstytucyjnego, wyprowadza się wprost z konstytucji. Ich uściśleniem i dopełnieniem są zasady opodatkowania według zdolności świadczenia oraz zgodnie z ustawowym stanem faktycznym.
„Świat nam się przewrócił do góry nogami”. Relacje kobiet po narodzinach dziecka
Authors: Stankowska Magdalena
Published: February 2023

W artykule omówiono zagadnienie zmian, które dokonują się w bliskim związku, kiedy parze rodzi się dziecko. Zaprezentowano wyniki badań jakościowych – 46 wywiadów pogłębionych przeprowadzonych z matkami małych dzieci. Inspirację teoretyczną dla przedstawionych analiz stanowi teoria praktyk rodzinnych D.H.J. Morgana. Zastosowano analizę tematyczną. Rozmówczynie zwracały uwagę na następujące niekorzystne zmiany w związku, które nastąpiły po narodzinach dziecka: brak czasu i energii na budowanie relacji z mężem/partnerem, brak możliwości spędzenia czasu (w domu czy poza domem) bez dzieci, ograniczenie kontaktów seksualnych, napięcia, które mają na ogół charakter przejściowy. Nieliczne kobiety były zdania, że pojawienie się dziecka zbliżyło je do ich mężów/partnerów i miało korzystny wpływ na relacje w bliskim związku.

Актуальность. Одним из перспективных методов промыслово-геофизических исследований скважин является активная термометрия. Технология проведения исследований данным методом включает локальный индукционный нагрев металлической обсадной колонны, регистрацию и анализ изменения температуры в стволе скважины. В результате теплообмена с колонной в потоке жидкости, движущейся в скважине, создается тепловая метка, которая регистрируется температурными датчиками, расположенными в колонне по пути движения жидкости. Наблюдение за движением тепловых меток позволяет решать ряд важных практических задач, таких как определение объемного расхода флюида в стволе скважины, оценка дебита заколонного перетока. При низкой скорости потока разогрев колонны может привести к возникновению значительных градиентов температуры в жидкости, что обуславливает возникновение естественной тепловой конвекции. В этой связи актуальным является исследование тепловых процессов в скважине при индукционном нагреве с учетом естественной тепловой конвекции. Объект: добывающая скважина, в которой проводятся исследования методом активной термометрии с помощью локального индукционного нагрева обсадной колонны. Цель: исследование особенностей формирования температурного поля в скважине в процессе индукционного нагрева обсадной колонны с учетом естественной тепловой конвекции при малом расходе потока в колонне. Методы: численное моделирование в программном пакете Ansys Fluent (Лицензия ANSYS Academic Research CFD в рамках договора с Башкирским государственным университетом от 15.06.2020). Результаты. Установлено, что разогрев колонны и жидкости вблизи ее поверхности достигает около 12 и 5 К соответственно, что способствует увеличению локальной скорости жидкости за счет влияния естественной тепловой конвекции. Выше интервала нагрева в жидкости наблюдается повторяющаяся структура потока, соответствующая образованию конвекционных ячеек. Построены кривые динамики температуры жидкости во времени на различном радиальном расстоянии от стенки колонны и различной высоте относительно интервала нагрева, по времени прихода тепловой метки выполнена оценка линейной скорости потока жидкости. Установлено, что расчетная скорость жидкости, определяемая по скорости движения тепловой метки, возрастает на величину 6 % и более относительно скорости ламинарного восходящего потока в отсутствие влияния естественной тепловой конвекции. Показано, что измерение температуры в центральной части потока позволяет более точно оценить расход жидкости в колонне, поскольку в пристеночных областях локальная скорость жидкости возрастает за счет естественных конвективных потоков.
