Anarquismos, homossexualidade e queer
Authors: Lucchesi Flávia
Published: December 2022

Desde o final do século XIX, anarquistas se envolveram de maneiras diversas com a questão da homossexualidade. Dividiram-se entre reprimendas morais, a busca por “soluções” e a defesa das relações amorosas e práticas sexuais livres. Após 68, a proximidade entre anarquismos e essas outras práticas se estreitou no embate direto contra a moral e para revolver os costumes. Na década de 1990, irrompeu no interior do próprio movimento de gays e lésbicas uma força queer que confrontou a assimilação via reivindicação de direitos, políticas e a adequação às condutas e ao modo de vida heteronormativos. No novo século, em diversos cantos do planeta, eclodiu pelas ruas o anarcoqueer e a afirmação de lutas que desassossegam queers, anarquistas, o movimento LGBTQIA+ e que enfrentam a sociedade.

The study of the functional anatomy of the digestive system of fish, in particular the oropharyngeal cavity, is of great importance because it allows inferences about the feeding habit, mechanisms of capture, selection, and processing of food carried out by different species. Thus, the aim of this study was to describe the anatomical adaptations of the oropharyngeal cavity of the pirarucu (Arapaima gigas Schinz, 1822) using scanning electron microscopy (SEM) techniques. The oropharyngeal cavity of six specimens of pirarucu was collected in juvenile phase, from Aquaculture Research Center at the Universidade Federal de Rondônia (UNIR), created for commercial purposes. The anatomical pieces were fixed in 10% buffered formalin and processed for SEM analysis. Anatomically, the oropharyngeal cavity of the pirarucu is composed of five pairs of branchial arches, apical portion of the tongue, floor of the tongue, lower pharyngeal area, and upper pharyngeal plate. In SEM, we observed that the mucosa of the apex of the tongue and the upper pharyngeal roof have a smooth texture and are covered by squamous cells with numerous small openings scattered over the surface. The portions of the floor of the tongue and the lower pharyngeal area, on the other hand, have adaptations in the form of a projectile and numerous sensory papillae, giving a rough texture to the region. Thus, the oropharyngeal cavity of pirarucu is adapted for the capture, apprehension, and swallowing of its prey, with signs of carnivory.

Published: December 2022

Platform berbelanja online menjadi salah satu bukti perkembangan teknologi. Shopee sebagai Marketplace terbesar di Indonesia menyediakan sebuah metode pembayaran Shopee Paylater, metode yang memberikan kredit atau pinjaman kepada para pengguna. Shopee Paylater menjadi salah satu metode pembayaran yang diminati karena kemudahan dalam memberikan dana pinjaman bagi penggunanya. Karena kemudahannya banyak pengguna yang membeli barang karena spontanitas tanpa mempertimbangkan akibat apa yang akan terjadi setelah melakukan pembelian tersebut sehingga memunculkan sikap pembelian impulsif. Penelitian ini memfokuskan pada tujuan para mahasiswa menggunakan Paylater sebagai metode pembayaran dan perilaku konsumtif di kalangan mahasiswa sosiologi UNJ dengan menggunakan teori habitus menurut Pierre Bourdieu. Hasil penelitian menunjukkan bahwa mahasiswa menggunakan Shopee Paylater karena diskon-diskon yang ditawarkan sangat banyak sehingga mahasiswa tidak ingin diskon tersebut hangus begitu saja yang pada akhirnya melahirkan perilaku konsumtif dan melahirkan sifat impulsif. Alasan lainnya adalah Shopee Paylater memberikan kemudahan kepada mahasiswa untuk berbelanja ketika sedang tidak memiliki uang. Namun karena kemudahan tersebut melahirkan sikap pemborosan dan meningkatnya sifat impulsif.

Numerical Analysis of Air Exchange Between two Enclosed Spaces
Authors: Bouacha Nadjet , Bouguerra Abdesselam
Published: December 2022

The air quality problem has never been so acute as in this period of COVID-19. The three-dimensional modeling of thermo-aeraulic transfer in buildings is characterized by its complexity due to the large dimensions and the behavior’s laws problem of the fluids to be adopted. The number of finite elements increases with the processed volume, negatively impacting CPU time. Well-conducted numerical modeling can be more advantageous than an expensive experimental study requiring significant equipment, an extensive testing campaign, a large staff, and time. This work is aimed to carry out numerical modeling of an existing experimental device to simulate the effects of ventilation systems. We used the Computational Fluid Dynamics (CFD) code FLUENT. The results obtained showed good agreement with previous experimental data. A good correlation was obtained by analyzing temperature and velocity profiles in stationary and variable regimes. This validated modeling of the problem allows us to consider later, with sufficient confidence, reliable simulations of several other cases of air transfer to achieve new human comfort and health conditions.
Effects of differently aged biochar to soil NH3 volatilization, N2O emissions and microbial diversity, and interaction
Authors: Zhang Cong , Wang Zhenhong
Published: December 2022

Biochar has been considered an effective tool to alleviate soil ammonia (NH3) volatilization and nitrous oxide (N2O) emissions. However, there is often an aging phenomenon after the application of biochar, which brings uncertainty to the effectiveness of different aged biochar in alleviating global warming for a long time. The effect of aged biochar on soil NH3 volatilization, N2O emissions, and microbial diversity remains to be explored. In this study, different aged biochar was obtained by artificially accelerating physical, chemical, and biological aging and the intensity of biochar aging was quantified by an index. Then, the effects of aged biochar on soil NH3 volatilization, N2O emissions, and microbial diversity were determined through field control experiments and high-throughput sequencing. The results showed that biochar aging increased the acidity, oxygen content, specific surface area (SSA), total pore volume (PV), and the number of oxygen-containing functional groups in biochar, and effectively inhibited NH3 volatilization in soil. Compared with raw biochar, aged biochar by oxidation and mineralization significantly reduced NH3 volatilization by 14.71% and 9.39%. However, aged biochar increased the emission of soil N2O. Compared with raw biochar, biochar aged by oxidation and mineralization increased the N2O emissions by 30.34% and 26.36%. Biological and physical aging had no significant effect on soil NH3 volatilization and N2O emissions. Raw biochar increased the diversity of soil bacteria and decreased the diversity of nitrogen (N) fixing bacteria, but aged biochar just had converse effects on them. The alpha diversity of bacteria and fungi promoted NH3 volatilization and N2O emissions. The work clarifies the effects of different aged biochar on biochar properties, NH3 volatilization and N2O emissions, and soil microbe diversity.
Exploring the experience of appetite loss in older age: insights from a qualitative study
Authors: Dismore Lorelle , Sayer Avan , Robinson Sian
Published: December 2022

Background: Poor appetite is common in older age, with estimated prevalence figures ranging between 15-30% in community-dwelling populations. Despite known links between poor appetite and adverse health outcomes, appetite is not routinely assessed and the causes and impact of appetite loss in older age are not well understood. This study aimed to improve understanding of the influences on, and experiences of, appetite loss among older people who have poor appetite and to consider the implications for prevention and treatment strategies.
Methods: Thirteen older adults aged 60-93 years (9 women) identified as having poor appetite (Simplified Nutritional Appetite Questionnaire (SNAQ) scores <14; ranging from 8-11) took part in semi-structured interviews. Open-ended questions focused on influences on and experiences of appetite and appetite loss in older age. Interviews were transcribed; reflective thematic analysis was conducted using an inductive approach.
Results:The analysis generated three themes: 1) a complex web of influences on appetite loss, that include biological, psychological and social factors; 2) living with poor appetite - variation in perceptions of poor appetite and attitudes to appetite loss; 3) living with poor appetite - the role and importance of the eating environment and social interactions. The themes highlight marked differences in individual ‘journeys’ to poor appetite, with variation in the balance and role of specific causal influences, that impact on the experience of appetite loss and on coping strategies.
Conclusions: A broad range of influences (including biological, psychological and social factors) and experiences of appetite loss in older age were described. Future research should consider person-centred approaches, that take account of individual narratives of appetite loss, in the design of effective strategies to support older adults.

Background：Umbilical artery thrombosis is very rare and not easily detected by prenatal examination, but it can lead to adverse perinatal outcomes.
Objective：To investigate the clinical manifestations related to umbilical artery thrombosis, and to evaluate the best treatment plan and delivery mode.
Methods：Seven patients with umbilical artery thrombosis treated in Shandong Provincial Hospital from June 2020 to June 2022 were retrospectively studied. The patient's general condition (age, pregnancy complications, clinical manifestations, prenatal ultrasound), pregnancy outcome (mode of delivery, fetal outcomes) and clinical pathological characteristics of placentas were analyzed. Descriptive statistics were used to analyze the data.
Result：Except for one patient who was lost to follow-up, all patients (6/7) were delivered by cesarean section; blood clots in umbilical arteries were observed in all patients. Clinical pathological characteristics of placentas included blood stasis umbilical artery (6/6) and chorioamnionitis (2/4). Clinical diagnosis showed that the main symptoms were abnormal fetal heart monitoring (7/7), reduced fetal movement (2/7), the number of umbilical arteries changed indicated by ultrasound (4/7) and excessive umbilical cord torsion (2/7). All neonates survived, 5 (5/6) were transferred to neonatology for treatment, 4 (4/6) were premature, 2 (2/4) were low birth weight, and 1 (1/4) was very low birth weight.
Conclusion:We observed abnormal fetal heart monitoring, reduced number of fetal movements, prenatal ultrasound indicated changes in the number of umbilical arteries helped us to identify umbilical artery thrombosis early. Our results support emergency cesarean section as a method for better maternal and infant outcomes.

Background
The COVID-19 pandemic has negatively impacted surgical residency training worldwide. This study aims to evaluate the impact of the COVID-19 pandemic on surgical residency training and psychological well-being in a Tunisian residents cohort, and to emphasize on the importance of digital simulation-based training through a review of different tools reported in the literature.
Methods
A cross-sectional survey of surgical residents was conducted at our surgical division of the teaching hospital, between 1st and 30 December 2020. A study-specific electronic questionnaire designed using the free software Google Forms was distributed to 36 residents via emails and Whatsapp.
Results
At the end of the study period, only 26 participants (72%) completed and submitted the questionnaire. Most respondents reported the negative impact of the pandemic on clinical and surgical training. Anxiety was noticed in all participants; more than half presented depression. During the pandemic, clinical activity was mainly based on "patient bedside" learning (50%) and college courses via webinars (38.4%). Surgical training was mainly based on the medico-surgical encyclopedia (65.4%), surgical videos on YouTube® (61.5%) and emergent surgeries attendance (53.8%). There was a lack of didactic teaching programs implementation during the pandemic.
Conclusions
There is a pressing need to improve surgical training during residency. Simulation-based training using digital tools is the best way to improve psychomotor skills outside of the operating theatre.
Assessing Empirical Support for Replicator Dynamics in Financial Markets: A Maximum Entropy Method Tested with America’s Largest Companies
Authors: Fort Hugo
Published: December 2022

The replicator dynamics (RD) model provides important insights in the evolution of markets but lacks empirical support. A main difficulty is how to obtain the payoff matrix connecting the pairwise effects between interacting market entities. A procedure for estimating these pairwise payoffs, based on the Maximum Entropy (ME) principle, is proposed. The resulting method is thus called Replicator Dynamics Pairwise Maximum Entropy (RDPME). To test this method, daily market values from 2014 to 2019 of America’s top revenue companies are used. As it is customary in time series forecasting analysis, these series are divided into a training period, used to infer the RDPME parameters (intrinsic growth rates and payoff matrix), and a validation period, used to validate the model. Different partitions into training and validation periods are considered. The RDPME method outperforms the stochastic benchmark of the geometric random walk in predicting empirical shares for most of the companies along most choices of validation periods.

D'Alembert Wave Equation Misconception
Authors: N. Bharathraj G.
Published: December 2022

We analyse a simple one dimensional arrangement of identical springs coupled with identical masses to understand longitudinal oscillations on the spring-mass chain. D'Alembert wave eqn implies only one wave-speed value, there is no wave dispersion. Ab initio analysis of the normal modes suggests that wave-speed in a closed-chain has dispersion. In the open-chain case, we can realistically associate a wave-length and wave-speed only for about half the normal mode solutions, because the higher frequency half of the modes on open-chains do not have sinusoidal solutions. In the normal mode analysis we find sinusoidal variation of frequency wrt mode number, not linear as expected by the idea of harmonics. Framing of D'Alembert wave equation is untenable. It is purely a geometric construct without any Physics basis to it.

The changing climate leads to frequent low temperature events, which results in lower crop production worldwide. Plant growth and development are regulated by WRKYs, as well as a variety of defense responses, including salt, drought, and extreme temperature stresses. Here, a transcription factor AeWRKY31 was obtained from Abelmoschus esculentus and ectopic expressed in Arabidopsis thaliana. Molecular localization and self-transactivation assays revealed AeWRKY31 was a nuclear-localized protein with self-transactivation property. Subsequently, AeWRKY31 expression activated the expression of AtABA1, AtABA2, and AtNCED6, and promoted endogenous ABA accumulation, which induced stomata closure of transgenic Arabidopsis. Histochemical staining and ROS content determination demonstrated that AeWRKY31 expression inhibited the accumulation of H2O2 and O2- and decrease electrolyte leakage in transgenic lines. Meanwhile, compared with that of WT, relative expression levels of cold response-related genes were up-regulated in transgenic lines. Finally, AeWRKY31 transgenic Arabidopsis plants exhibited enhanced cold tolerance both in vivo and in vitro experiments. Our findings will benefit molecular breeding and anti-cold mechanism investigation of okra.

As the only first-line targeted therapy for advanced gastric cancer (GC) with HER2-positive status, the efficacy of trastuzumab is limited by the high rates of primary and secondary resistance. The therapeutic effect of many other HER2-targeted drugs is not satisfactory in GC. Previous studies have demonstrated that overexpression of S-phase kinase-interacting protein 2 (Skp2) predicted poor prognosis of HER2-positive GC and promoted cancer cell proliferation, resistance, and glycolysis. It has been proved that trastuzumab-resistant GC cells exhibit high glycolytic activity. We found thioridazine restores the sensitivity of trastuzumab in vivo and in vitro by inhibiting Skp2 expression and glycolytic activity. Moreover, thioridazine combined with lapatinib also showed strong inhibitory effects on the growth and survival of trastuzumab-resistant GC cells. Collectively, these data introduce a thioridazine-based therapy to overcome trastuzumab resistance in GC.

In order to meet the needs of intelligent ships to capture and grasp small targets while navigating on water and to be able to sense and avoid small targets, a water target detection method based on the YOLOv5-s algorithm is proposed, and the experimental equipment is allowed to perform real-time and high-precision target recognition and sensing in a dynamic water environment. This method uses the view acquisition by using the ZED 2i binocular camera, and the RGB images obtained by the binocular camera are used as the input of the feature fusion module to improve the YOLOv5-s algorithm to obtain the position information of the small target on water in the acquired image, and the relative position about the camera is calculated by combining the pixel position information obtained by the binocular camera. At the same time, in order to ensure the detection accuracy, the sample anchor frames of some datasets are updated according to the detection results; then the dataset is retrained; the images acquired through the binocular camera are corrected for distortion and stereo correction, etc., to make the detection accuracy higher; the experimental results show that the detection accuracy of combining the binocular camera with the improved YOLOv5-s algorithm is better than that of other methods for small target detection on water and better than the original algorithm The evaluation index map_0.5 is as high as 9.79%, and the detection accuracy error of the lateral detection of the target on water is kept at about 6.6%, and the lateral detection accuracy within 20 meters is about 8.7%. The obtained results can reliably provide a valuable basis for autonomous intelligent ships to work in complex water environment.

In principal component analysis, data logarithm transformation and row vector centralization improvement are carried out, reducing the input, and simplifying the network model. Use sparrow search algorithm for optimization, and compare the performance with cuckoo algorithm, seagull algorithm, and whale algorithm. To avoid problems as slow convergence speed and insufficient exploration ability, an improved sparrow search algorithm integrating refraction inverse learning mechanism, sin-cosine and Cauchy variation is proposed, a high-precision PCA-SCSSA-Elman neural network prediction model is established. The results show that SSA-Elman neural network has the fastest convergence speed and the optimal performance value is 0.1391 higher. Combined with the extracted principal component data, compared with PCA-Elman, PCA-SSA-Elman and PCA-SineSSA-Elman prediction models, the mean absolute error is higher than the other three models [45.6850%, 14.9168%, 11.7448%], the prediction error is minimal. The results show that the improved sparrow search algorithm can significantly improve the convergence speed and optimization accuracy.
