Simulated long-term evolution of the thermosphere during the Holocene – Part 1: Neutral density and temperature
Authors: Cai Yihui , Yue Xinan , Zhou Xu , Ren Zhipeng , Wei Yong , Pan Yongxin 
Published: May 2023

Abstract. In the previous work of Yue et al. (2022),
the ionospheric evolution during the Holocene (9455 BC to 2015 AD) was
comprehensively and carefully investigated for the first time using the
Global Coupled Ionosphere-Thermosphere-Electrodynamics Model developed at
the Institute of Geology and Geophysics, Chinese Academy of Sciences
(GCITEM-IGGCAS), driven by realistic geomagnetic fields, CO2 levels,
and solar activity derived from ancient media records and modern measurements. In this study, we further quantify the effects of the three
drivers on thermospheric neutral density and temperature variations during
the Holocene. We find that the oscillations of solar activity contribute
more than 80 % of the thermospheric variability, while either CO2 or
the geomagnetic field contributes less than 10 %. The effect of CO2
on the global mean neutral density and temperature is comparable to that of
the geomagnetic field throughout the Holocene but is more significant after
1800 AD. In addition, thermospheric density and temperature show
approximately linear variations with the dipole moment of the geomagnetic
field, CO2, and F10.7, with only the linear growth rate associated with the geomagnetic field varying significantly in universal time and latitude.
The increasing dipole moment and CO2 cool and contract the
thermosphere, while solar activity has the opposite effect. The higher the
altitude, the greater the influence of the three factors on the
thermosphere. Different factors produce different seasonal variations in
thermosphere changes. Furthermore, we predict that a 400 ppm increase in
CO2 will result in a 50 %–70 % and 84–114 K reduction in global mean
neutral density and temperature, respectively, which should directly affect
the orbit and lifetime of spacecraft and space debris.

Abstract. This study is based on multiproxy data gained from a 14C-dated 6.5 m long sediment core and a 210Pb-dated 23 cm short core retrieved from Lake Rauchuagytgyn in Chukotka, Arctic Russia. Our main objectives are to reconstruct the environmental history and ecological development of the lake during the last 29 kyr and to investigate the main drivers behind bioproduction shifts. The methods comprise age-modeling, accumulation rate estimation, and light microscope diatom species analysis of 74 samples, as well as organic carbon, nitrogen, and mercury analysis. Diatoms have appeared in the lake since 21.8 ka cal BP and are dominated by planktonic Lindavia ocellata and L. cyclopuncta. Around the Pleistocene–Holocene boundary, other taxa including planktonic Aulacoseira, benthic fragilarioid (Staurosira), and achnanthoid species increase in their abundance. There is strong correlation between variations of diatom valve accumulation rates (DARs; mean 176.1×109 valves m2 a1), organic carbon accumulation rates (OCARs; mean 4.6 g m−2 a−1), and mercury accumulation rates (HgARs; mean 63.4 µg m−2 a−1). We discuss the environmental forcings behind shifts in diatom species and find moderate responses of key taxa to the cold glacial period, postglacial warming, the Younger Dryas, and the Holocene Thermal Maximum. The short-core data likely suggest recent change of the diatom community at the beginning of the 20th century related to human-induced warming but only little evidence of atmospheric deposition of contaminants. Significant correlation between DAR and OCAR in the Holocene interglacial indicates within-lake bioproduction represents bulk organic carbon deposited in the lake sediment. During both glacial and interglacial episodes HgAR is mainly bound to organic matter in the lake associated with biochemical substrate conditions. There were only ambiguous signs of increased HgAR during the industrialization period. We conclude that if increased short-term emissions are neglected, pristine Arctic lake systems can potentially serve as long-term CO2 and Hg sinks during warm climate episodes driven by insolation-enhanced within-lake primary productivity. Maintaining intact natural lake ecosystems should therefore be of interest to future environmental policy.

Implementação do Novo Ensino Médio no Estado do Acre: a Experiência das Escolas-Piloto
Authors: De Oliveira Adriana Martins , Da Silva Monica Ribeiro 
Published: May 2023

O artigo analisa os primeiros movimentos da implementação da reforma do ensino médio no estado do Acre, a partir da experiência das escolas-piloto. Trata-se de uma pesquisa de campo, com a realização de questionários e entrevistas com gestores, coordenadores de ensino, coordenadores pedagógicos e professores. Para a interpretação e análise dos dados utilizou-se como referencial teórico as formulações de Basil Bernstein (1996; 2003) no que se refere ao movimento de recontextualização. Por recontextualização, entende-se o processo de apropriação dos documentos oficiais da reforma por meio dos quais os sujeitos escolares descontextualizam e atribuem sentidos adicionais, produzindo novas práticas discursivas e pedagógicas por vezes distintas das originais. As categorias utilizadas para análise dos dados foram flexibilização curricular, protagonismo juvenil, projeto de vida, empreendedorismo e relação público-privada, definidas a priori, com base na leitura dos documentos normativos nacionais da reforma do Ensino Médio. Os resultados revelam a existência de movimentos de recontextualização das proposições presentes nos documentos normativos nacionais da reforma pelos sujeitos das escolas-piloto ao atribuírem significados próprios às finalidades, sentidos, orientações e prescrições dos documentos normativos oficiais.

Published: May 2023

Introduction: Pregnant patients are at risk of several possible complications during the peripartum period. Amniotic fluid embolism (AFE) is a peripartum complication with high mortality and morbidity. The sudden entry of amniotic fluid into the maternal circulation causes a rapid and dramatic sequence of clinical events called AFE. The reported incidence of AFE after a cesarean section is around 19%, and after a normal delivery, it is 11%. AFE causing multiple embolisms is not reported in the literature, nor is the use of point-of-care ultrasound (POCUS) in the diagnosis of AFE. We report a case of AFE causing pulmonary and ovarian embolisms.
Case: A 34-year-old pregnant lady had an elective lower section cesarean section (LSCS) for transverse lying and placenta previa under combined spinal and epidural anesthesia. She was gravida 3 para 2 and had regular antenatal check-ups, and she presented for her LSCS at 36 weeks of gestation. Immediately after delivery of the fetus, the patient had convulsions, cardiac arrest, and disseminated intravascular coagulopathy (DIC). Immediately, cardiopulmonary resuscitation started, and the team achieved a return of spontaneous circulation (ROSC) in 3 minutes. DIC was corrected with blood and blood products during this maneuver, and POCUS of the inferior vena cava and heart showed multiple small particles floating, thus confirming the diagnosis of AFE in this patient. The patient was transferred to the intensive care unit (ICU), intubated, and ventilated, necessitating a vasopressor infusion. Computed tomographic pulmonary angiography (CTPA) showed pulmonary embolism and ovarian vein embolism, which were managed with heparin infusion. She was hemodynamically stable and weaned from vasopressors, and the ventilator was then extubated on day 13 of ICU admission. She remained awake and in stable condition. The patient was transferred to the ward and subsequently discharged to go home on the 20th-day post-delivery.
Conclusion: AFE can be quickly diagnosed using clinical manifestations and POCUS, and it can be managed early for better patient outcomes. POCUS will show multiple smaller and a few larger amniotic fluid emboli in the heart and vena cava. These larger AFE emboli can migrate and cause multiple embolisms, requiring systemic anticoagulation.

This study examined the effect of International Accounting Standards (IAS) 38 intangible assets on the firm performance of selected consumer manufacturing companies listed in Nigeria. The study employed secondary data extracted from the published financial statements of the sampled 15 companies out of a population consisting of 20 selected consumer goods manufacturing companies listed in Nigeria using a purposive sampling technique. A firm observation of 220 participants over 11 years from 2011 to 2021 was used in the study. Descriptive statistics and inferential analysis were adopted in the data analysis. The study revealed that intangible assets had a positive and significant effect on earnings per share (EPS) and the return on shareholders funds (SHF). The study concluded that the firm performance of selected consumer goods manufacturing companies in Nigeria was significantly affected by IAS 38 intangible assets. These findings suggest that compliance with IAS 38 standards is critical as it further deepens the relevance and faithful representation of financial statements prepared in Nigeria.

Published: May 2023

Reaktor Daya Eksperimental (RDE) is a high-temperature gas-cooled reactor (HTGR) for electricity generation, heat generation, and hydrogen production by Batan. Empirical and numerical calculations are needed to strengthen the existing design. The numerical method by computational fluid dynamic (CFD) analyzes temperature distribution and pressure drop along the pipe. The Batan RDE steam generator design has a seven-layer helical pipe model, while this research uses a one-layer helix pipe. In empirical calculations, the heat transfer region has three sections; single-phase liquid, two-phase, and single-phase vapor heat transfer. In numerical calculations, apply the assumption of constant heat flux and constant working fluid properties. The results of empiric calculations data showed that the helical pipe height was 3.98 m, shorter than the Batan design, which is 4.97 m. This considerable difference due to empirical calculations did not cover the safety factor. The results of numerical calculations show that in the single-phase, empiric calculation data were acceptable since the different values of numerical calculations for empiric calculations data were below 10%. Meanwhile, the case of the two-phase numerical calculations is not satisfactory and needs further research to obtain optimal results.
First Principles study of Silver Argyrodites-structured compounds A8BC6 (A=Ag; B=Si, Ge; C=Te) for Opto-electronic application
Authors: Munsif Muhammad , Shah Matiullah 
Published: May 2023

The structural and optical properties of a material are studied using Density Functional Theory. By the method of full potential linearized augmented plane wave (FP-LAPW) silver argyrodites Ag8SiTe6 and Ag8GeTe6 has been investigated. To obtain stable geometry of A8BC6 materials, the energy minimization approach is applied. The Generalized Gradient Approximation (GGA) approach is used to optimize the crystal structure of the Argyrodites materials. All these compounds crystalize in a cubic unit cell with lattice constant increasing from 12.13 Å (Si) to 12.28 Å (Ge). The mBJ-functional shows a semiconducting nature Ag8SiTe6 for and metallic nature for Ag8GeTe6 of these compounds with an indirect band gap lying at the L-X symmetry points with a band gap of 0.24 eV (Si) and 0.0068 eV (Ge) to obtain the optical properties such as refractive index, complex dielectric constant with real and imaginary part of dielectric function, and other optical properties are discussed. Effective mass of electrons is smaller than those of holes resulting in higher carrier mobility for electrons. Due their direct band gap, these Argyrodites materials could be particularly useful in optoelectronic devices.
Horizontes críticos y constructivos en el pensamiento de Luce Irigaray. Notas para una lectura de Speculum: de l'autre femme
Authors: Ugalde Guajardo Andrea 
Published: May 2023

La publicación de Speculum: de l’autre femme en 1974, segunda tesis doctoral de la filósofa, psicoanalista y lingüista Luce Irigaray, produjo un revuelo inusitado, expresado tanto en los modos en que se recepcionó la obra, como en la trayectoria de la propia autora. Sus resonancias, presentes aún hoy, están relacionadas con la contundencia de su espíritu crítico, con el estilo lúdico y a momentos hermético de su escritura, y con la profundidad filosófica de los interlocutores que Irigaray convoca para que se presenten en esta inusual escena de experimentación escritural.
En varias ocasiones, la autora ha señalado que su trayectoria de pensamiento responde a la dinámica de elementos críticos y constructivos, que se van entrelazando en una especie de continuum. Si seguimos esta clave de lectura, Speculum puede ser leído como un ejercicio de pensamiento que se da en el trasfondo de una tensión entre, por una parte, las intervenciones críticas en el canon filosófico occidental y el discurso psicoanalítico, y por otra, la necesidad de pensar las condiciones para transformar toda una cultura. En lo que sigue, quisiera explorar esta clave de lectura y evaluar sus alcances y posibilidades, proponiendo algunas herramientas conceptuales que se irán presentando a lo largo de la exposición.
سلطة صاحب العمل في تعديل عقد العمل بين الاتجاهات التقليدية والاتجاهات الاجتهادية بحث مقارن في القانون اللبناني والمصري والفرنسي
Authors: دغمان محمد 
Published: May 2023

إنّ سلطة صاحب العمل في تعديل عقد العمل الناتجة عن سلطته في إدارة المؤسسة ليست مطلقة، فيجب إلاّ تكون تعسفية وألّا تتضمن إساءة للأجراء. فالظروف الاجتماعية والاقتصادية للأجراء والمؤسسة على حد سواء تؤدي دوراً مهماً في هذا الصعيد، وأنه من الصعوبة بمكان وضع تشريع ينظّم ممارسة هذه السلطة، لذا فإنّ القضاء يملك سلطة تقديرية واسعة في هذا الميدان مما أوجد أحكاماً متناقضة من حيث المضمون ولكنها منسجمة مع ظروف كل قضية.
وعلى كل حال، فإنّ القيد الأهم في تحديد هذه السلطة هو مبدأ القوة الملزمة للعقد، فلا يجوز قبول تعديل العقد بإرادة صاحب العمل المنفردة، وفي الوقت نفسه تجاهل سلطة صاحب العمل في تنظيم المؤسسة، والتوفيق بين الأمرين اقتضى التمييز بين الاتجاهات التقليدية التي ميّزت بين تعديل العناصر غير الجوهرية وتعديل أحد العناصر الجوهرية، وبين الاتجاهات الاجتهادية التي تبنّت تقسيماً جديداً ميّزت فيه بين تعديل عناصر العمل وتعديل شروط العمل.
