Published: December 2023

Background conventional coronary artery bypass grafting (CCABG) tends to cause severe complications in patients with comorbid Coronary Artery Diseases (CAD) and diabetes. On the other hand, the Minimally Invasive Cardiac Surgery Coronary Artery Bypass Grafting (MICS CABG) via transthoracic incision is associated with rapid recovery and reduced complications. Adding to the limited literature, this study compares CCABG and MICS CABG in terms of efficacy and safety.Methods Herein, 104 CCABG and MICS CABG cases (52 cases each) were included. The patients were recruited from the Minimally Invasive Cardiac Surgery Center, Anzhen Hospital, between January 2017 and December 2021 and were selected based on the Propensity Score Matching (PSM) model. The key outcomes included All-cause Death, Myocardial Infarction (MI), Cerebrovascular Events, revascularization, Adverse Wound Healing Events and one-year patency of the graft by coronary CTA.Results Compared to CCABG, MICS CABG had longer surgical durations[4.25 (1.50) h vs.4.00 (1.13) h, p = 0.028], but showed a reduced intraoperative blood loss [600.00 (400.00) mL vs.700.00 (300.00) mL, p = 0.032] and a lower secondary incision debridement and suturing rate (5.8% vs.19.2%, p = 0.038). No statistically significant differences were found between the two groups in the cumulative Major Adverse Cardiovascular and Cerebrovascular Events (MACCEs) incidence (7.7% vs. 5.9%), all-cause mortality (0 vs. 0), MI incidence (1.9% vs. 2.0%), cerebral apoplexy incidence (5.8% vs. 3.9%), and repeated revascularization incidence (0 vs. 0) (p > 0.05). Additionally, coronary CTA results revealed that the two groups’ one-year graft patency (94.2% vs. 90.2%, p = 0.761) showed no statistically significant difference.Conclusion In patients with comorbid CAD and diabetes, MICS CABG and CCABG had comparable revascularization performances. Moreover, MICS CABG can effectively reduce, if not prevent, poor clinical outcomes/complications, including incision healing, sternal infection, prolonged length of stay, and slow recovery of body function in diabetes patients.
Predictive value of MRI for identifying symptomatic neurovascular compressions in classical trigeminal neuralgia: A PRISMA-compliant meta-analysis
Authors: Zhao Wei , Yin Changyou , Ma Lei , Ding Mingzeng , Kong Wei , Wang Yanbin
Published: December 2023

Background
Patients with trigeminal neuralgia frequently undergo magnetic resonance imaging (MRI) prior to surgery. In patients without the signs and symptoms of face discomfort, MRI has shown the presence of neurovascular contact (NVC) in humans. Therefore, its capacity to accurately exclude NVC of the trigeminal nerve is not properly understood. A meta-analysis of the literature satisfied the criteria to further explore the value of MRI for the diagnosis of classical trigeminal neuralgia (CTN).
Study Design
The association between the symptomatic and asymptomatic trigeminal nerves, NVC, root entry zone (REZ), non-REZ, and anatomical variation was measured by a comprehensive review and meta-analysis of 13 observational studies using MRI for CTN neurovascular compression diagnosis.
Objectives
This study aimed to evaluate the effectiveness of MRI in detecting the neurovascular compression that causes symptoms in individuals with classic trigeminal neuralgia.
Setting
This study was conducted at the Department of Neurosurgery, Yantai Yuhuangding Hospital, Qingdao University.
Methods
Digital searches of PubMed, Embase, and the Cochrane Library were performed to identify studies published until December 31, 2022. The following were evaluated: 1) MRI evidence of NVC in symptomatic and asymptomatic trigeminal nerves; 2) MRI indication of NVC at the REZ in symptomatic and asymptomatic trigeminal nerves; 3) MRI substantiation of non-REZ neurovascular contact in patients with CTN; and 4) asymptomatic and symptomatic anatomical changes at the NVC site of the trigeminal nerves. Odds ratios (ORs) with 95% confidence intervals (CIs) were calculated using the fixed effects models.
Results
Thirteen observational studies were analyzed. First, MRI of 88.2% of symptomatic versus 36.3% of asymptomatic trigeminal nerves revealed marked differences in NVC in the REZ. Second, pooled data showed that REZ NVC was detected in 78.6% of symptomatic and 37.9% of asymptomatic nerves. Third, MRI analysis of NVC in the non-REZ revealed no differences between 12.1% asymptomatic nerves and 16.5% symptomatic nerves, and MRI revealed marked differences in 53.2% symptomatic and 7.9% asymptomatic anatomic changes at the NVC site of the trigeminal nerve.
Limitations
Despite the systematic evaluation of 13 observational studies, large-scale randomized controlled trials should be conducted, focusing on the specificity of MRI for the diagnosis of trigeminal neuralgia and evaluating the specificity of the imaging findings and the impact of the patient's postoperative treatment.
Conclusions
A previous meta-analysis showed that patients with CTN were more likely to have NVC-specific anatomical changes. MRI of patients with CTN can detect anatomical changes in the REZ NVC with higher sensitivity.

Published: December 2023

Introduction ​This study identifies approaches to quality improvement for women with disabilities in Nepal from the perspective of the women themselves and the policymakers. Nepal has seen significant progress in maternal healthcare, including a marked reduction in maternal mortality. However, this progress masks disparities, particularly for women with disabilities. The study aims to address the gap in quality of maternal healthcare for these women, in light of Nepal’s evolving healthcare policies and federal structure. Studies have been conducted on quality improvement for maternal health but few studies have been done from both perspectives.Methods Qualitative data was collected through in-depth semi-structured interviews with two groups: 12 women with visual and physical disabilities, and 12 policymakers at different administrative levels. Conducted in the outskirts of Kathmandu, these interviews were audio-recorded, transcribed, translated into English, and analyzed thematically.Results Women with disabilities in Nepal highlighted significant healthcare challenges, including inadequate disability-friendly infrastructure, scarce resources like wheelchairs and interpreters, understaffing, financial barriers, and lack of adequately trained healthcare staff. They advocated for better policy enforcement, increased staff training, and self-education on disability effects. Policymakers acknowledged these issues, noting improvements in infrastructure after the 2015 federalization of Nepal, but noted financial constraints and a lack of staff training and awareness. They suggested leveraging private funds and NGO collaboration for better resource allocation and emphasized the potential of local government initiatives for more tailored healthcare solutions.Conclusion In this study examining healthcare quality improvements, women with disabilities and policymakers agreed on the necessity of enhanced infrastructure, resources, and state financing, but diverged in their perceptions of progress and implementation strategies. Policymakers view current efforts optimistically and favor leveraging private funding, whereas women report insufficient improvements and neglect. Both groups value healthcare provider training, yet differ on approaches to achieve it. To address these disparities, the study recommends interactive workshops for shared understanding, strategic optimization of state spending, and curriculum updates to include specialized training for healthcare providers, aiming to unify efforts towards better healthcare for women with disabilities.

Published: December 2023

Purpose
To investigate the AMPK/CREB pathway–mediated effect of alpha-lipoic acid (ALA) on the sciatic nerve of rats with diabetic peripheral neuropathy (DPN) and to attempt to elucidate the underlying mechanism.
Methods
In vivo experiment, healthy male Sprague-Dawley (SD) rats were induced by high-carbohydrate/high-fat diet and intraperitoneal injection of streptozotocin (STZ) (30 mg·kg− 1) to induce diabetes. The diabetes SD rats were randomly divided into DPN group and alpha lipoic acid (ALA) group (n = 15). The other 15 SD rats were set as Control group. Then Control group and DPN group received the same amount of normal saline by intragastric administration, and ALA groups received ALA intervention every day for 12 weeks. Motor nerve conduction velocity (MNCV) and Paw Withdrawal Threshold (PWT) were detected. The morphological changes were observed by HE staining in sciatic nerves. Kinesin family member 5A (KIF5A), Dynein Cytoplasmic 1 Intermediate Chain 2 (DYNC1I2), phosphorylated Adenosine 5'-monophosphate (AMP) activated protein kinase (p-AMPK), Adenosine 5'-monophosphate (AMP) activated protein kinase (AMPK), phosphorylated cAMP responsive element binding protein(p-CREB) and cAMP responsive element binding protein(CREB)were observed by immunofluorescence assay and Western blot. In the vitro cell experiment, the NSC34 cells injury model was established by treating with 50 mmol·L− 1 of high glucose and 250 µmol·L− 1 of palmitic acid sodium. NSC34 cells were randomly divided into Control group, Model group and alpha lipoic acid intervention group (ALA group). ALA group was given corresponding ALA for 24 hours of intervention. The axon changes were observed by measured neuron axon length in NSC34 cells. KIF5A, DYNC1I2, p-AMPK,AMPK, p-CREB and CREB were observed by immunofluorescence assay and Western blot.
Results
ALA improved the MNCV and PTW of rats with DPN and reduced their mechanical pain threshold. AMPK was activated by ALA. p-CREB, KIF5A expression was upregulated, while DYNC1I2 expression was downregulated. ALA regulates mitochondrial transport in peripheral nerve.
Conclusion
ALA activates CREB and KIF5A through AMPK, regulates positive mitochondrial transport, protects axons, and attenuates DPN.

Published: December 2023

Concerning the power quality (PQ) issues in the power distribution network (PDN) due to load uncertainties and improper impedance matching of the inductances, deep reinforced learning (DRL) based inductively coupled DSTATCOM (IC-DSTATCOM) is proposed. First, by analyzing the impedance matching principle, the expression of source, load and filter current is derived with the help of inductive transformer. And second, an individual DRL subnet structure is accumulated for each phase using mathematical equations to perform the better dynamic response. The constraints like poor adaptability and PQ obtained from the direct coupled distributed static compensator (DC-DSTATCOM) due to uncertainties of loads is considered to improve the filtering performance. The IC-DSTATCOM is augmented better dynamic performance in terms of harmonics curtailment, improvement in power factor (PF), load balancing, potential regulation etc. The benchmark IEEE-519-2017 and IEC-61000-1 grid code are used to evaluate the effectiveness of the simulation and experimental study. Index Terms-PQ, PDN, DC-DSTATCOM, IC-DSTATCOM, and DRL algorithm. I. INTRODUCTION DC-DSTATCOM has achieved a great success in terms of shunt compensation for the PDN. There are several suggested improvement are being considered to improve the performance of the DC-DSTATCOM. The prime objectives such as harmonics curtailment, improvement in PF, load balancing, and potential regulation are considered. The drawbacks of DC-DSTATCOM has raised the important conceren related issues due to the flow of short circuit current at point of common coupling (PCC), poor protection and thermal issues. Considering the medium and long term development plan for “automotive industry” regulated by Ministry of Industry and Information Technology, It is encouraged for the development of IC-DSTATCOM.
Using qualitative system dynamics modeling to understand overdose bystander behavior in the context of Connecticut’s Good Samaritan Laws and identify effective policy options
Authors: Thompson Rachel , Sabounchi Nasim S. , Ali Syed Shayan , Heimer Robert , D’Onofrio Gail , Heckmann Rebekah
Published: December 2023

Background: Good Samaritan Laws (GSLs) are a harm reduction policy intended to facilitate a reduction in fatal opioid overdoses by enabling bystanders, first responders, and health care providers to assist individuals experiencing an overdose without facing civil or criminal liability. However, GSLs may not be reaching their full impact in many communities due to a lack of knowledge of GSL protections, distrust in law enforcement, and fear of legal consequences among potential bystanders. The purpose of this study was to develop a systems understanding of the factors influencing bystander responses to opioid overdose in the context of Connecticut’s GSLs and identify high-leverage policies for improving opioid-related outcomes and GSL implementation in Connecticut (CT).
Methods: We conducted six group model building (GMB) workshops that engaged a diverse set of participants with medical and community expertise and lived bystander experience. Through an iterative, stakeholder-engaged process, we developed, refined, and validated a qualitative system dynamics (SD) model in the form of a causal loop diagram (CLD).
Results: Our resulting qualitative SD model captures our GMB participants’ collective understanding of the dynamics driving bystander behavior and other factors influencing the effectiveness of GSLs in the state of CT. In this model, we identified seven balancing (B) and eight reinforcing (R) feedback loops within four narrative domains: Narrative 1 - Overdose, Calling 911, and First Responder Burnout; Narrative 2 - Naloxone Use, Acceptability, and Linking Patients to Services; Narrative 3 - Drug Arrests, Belief in Good Samaritan Laws, and Community Trust in Police; and Narrative 4 - Bystander Naloxone Use, Community Participation in Harm Reduction, and Cultural Change Towards Carrying Naloxone.
Conclusions: Our qualitative SD model brings a nuanced systems perspective to the literature on bystander behavior in the context of GSLs. Our model, grounded in local knowledge and experience, shows how the hypothesized non-linear interdependencies of the social, structural, and policy determinants of bystander behavior collectively form endogenous feedbacks that can be leveraged to design policies to advance and sustain systems change.

Authors: Usman Fathima Nausheen , Singhal Naveen Kumar
Published: December 2023

Experiments were designed to establish the hepatoprotective activity of Plumbago zeylanica (EPZE) ethanolic Root extracts at different doses (100 and 200 mg/kg bw) against thioacetamide-induced liver damage in albino Wistar rats. Hepatotoxicity was assessed by evaluating the activity of liver- function marker enzymes such as aspartate transaminase, alanine transaminase, alkaline phosphatase and lactate dehydrogenase as well as antioxidant enzymes such as catalase, glutathione peroxidase, glutathione reductase, Glutathione-S-transferase and reduced glutathione. Lipid peroxidation was measured as malonaldehyde, a thiobarbituric acid reactive substance. Liver histopathological changes were also evaluated. EPZE administration was found to markedly prevent the elevation of serum liver enzymes and conjugated dienes, and significantly increase hepatic levels of antioxidant markers. Histological findings also confirmed the EPZE protective effects on thioacetamide-induced hepatotoxicity. Thus, results from the present study demonstrate the antioxidant and hepatoprotective activity of EPZE, strongly suggesting that it could be used as a rich source of natural antioxidants.

Published: December 2023

With growing demand for renewable energy, it is urgent to develop prominent and robust transition metal electrocatalysts toward direct methanol fuel cell (DMFC). Nevertheless, the limited intrinsic activity of non-noble metal catalysts impeded their wide applications. To promote the electronic property of the non-noble metal catalysts, generating oxygen vacancies in non-noble metal catalysts could effectively modulate the intrinsic properties, resulting in significantly enhanced electrocatalytic performances. Herein, NiMn LDH/N-enriched carbon matrix with abundant oxygen vacancies (Ov-NiMn LDH/NCM) was achieved toward the methanol oxidation reaction through the simple hydrothermal approach. Remarkably, the optimal Ov-NiMn LDH/NCM exhibits outstanding methanol oxidation activity. The onset oxidation potential for methanol oxidation shifts negatively about 53 mV in comparison to Ni(OH)2/NCM. The current density activity of Ov-NiMn LDH/NCM reaches 38.4 mA·cm− 2, which is 1.6 folds than that of Ni(OH)2/NCM (24.0 mA·cm− 2) in 0.1 M KOH with 0.10 M methanol at the potential of 0.6 V vs. Ag/AgCl. The excellent performances for methanol oxidation reaction are attributed to the oxygen vacancies, which can significantly exposing the active sites and accelerate the charge transfer ability of the electrocatalysts. This work provides an effective avenue to construct the efficient and robust electrocatalysts toward methanol oxidation reaction.
Significant Role of 1,25-Dihydroxyvitamin D on Serum Calcium Levels After Total Thyroidectomy: A Prospective Cohort Study
Authors: Yamashita Hiroyuki , Mori Yusuke , Shindo Hisakazu , Yoshimoto Kouichi , Tachibana Seigo , Fukuda Takashi , Takahashi Hiroshi
Published: December 2023

Purpose
To comprehensively investigate the effects of 1,25-dihydroxyvitamin D (1,25(OH)2D) on calcium (Ca) concentrations after total thyroidectomy.
Methods
Serum Ca, parathyroid hormone (PTH), and 1,25(OH)2D levels were measured in 82 patients with thyroid disease before and after surgery.
Results
Serum Ca, PTH, and 1,25(OH)2D levels decreased significantly on the morning of the first postoperative day. Notably, the decrease in 1,25(OH)2D concentration was significantly lower than that of the PTH concentration (10.5% ± 33.4% vs. 52.1% ± 30.1%, p < 0.0001), with 28% of patients showing increases in 1,25(OH)2D. A high pre-operative 1,25(OH)2D concentration was the only factor to predict a postoperative 1,25(OH)2D decrease. Postoperative 1,25(OH)2D concentrations and the magnitude and rate of decrease from preoperative levels showed strong positive correlations with preoperative 1,25(OH)2D concentrations (p < 0.0001 for all three variables) but not with PTH concentrations. These findings suggest that 1,25(OH)2D concentrations after thyroidectomy were more strongly dependent on preoperative concentrations than on the effect of PTH decrease and were relatively preserved, possibly preventing sudden severe postoperative hypocalcemia. A high 1,25(OH)2D level was the most important preoperative factor for hypocalcemia (< 2 mmol/L; p < 0.05) on the first postoperative day; however, when intraoperative factors were added, only the decrease in PTH was significant (p < 0.001). In the PTH > 10 pg/mL group, a decrease in 1,25(OH)2D was significantly associated with postoperative hypocalcemia (p < 0.05). Similarly, in the PTH levels > 15 pg/mL group, a decrease in 1,25(OH)2D concentration was a significant factor, and the amount of PTH decrease was no longer significant.
Conclusions
1,25(OH)2D plays an important role in preventing sudden, severe hypocalcemia due to decreased PTH levels after total thyroidectomy, whereas high preoperative 1,25(OH)2D levels are a significant risk factor for postoperative hypocalcemia. Optimizing preoperative protocols to adjust Ca, PTH, and 1,25(OH)2D levels may reduce the risk of hypocalcemia.

Mixing of powders under periodic shear stress: effect of initial filling level
Authors: Obregón-Quiñones Luis Guillermo , Velázquez-Figueroa Carlos , Vanegas-Chamorro Marley Cecilia
Published: December 2023

Powder Mixing continues being of great importance in the field of particle technology because of the challenge to get homogeneous mixtures at a large scale. However, it is still moderately understood because of the complexity of designing 3D experiments that consider all the factors affecting the powder flow and powder mixing, hindering the acquisition of enough data that would provide a basic conception of powder behavior. This study involves a simple granular material mixing system of low friction that has five walls, where two of them are high friction moving walls following a cyclic function, and the others are non-friction static walls. The purpose was to create a complete set of 3D experiments of powder distribution to have a better insight into the inside mixing behavior as a function of the initial powder filling level. Experiments at different filling heights were run, obtaining the best mixing at the highest filling level. It was obtained a non-mixing zone with a triangle shape highly affected by the column particle weight. The increase of the vertical component of the resultant force produced by the acrylic motion walls causes a high momentum transfer in the x, y and z directions resulting in a decrease in the no-mixing zone. It was found an asymptotic behavior of the triangle height as a function of the initial filling height of the powders which indicates that values above a limited initial filling level will not have a significant effect on the triangle. A filling height increment of 100 % from 3.81 to 7.62 cm causes an increase in the mixing of 4.44 %. DEM simulations for mixing in the low-shear equipment were run to compare the experimental work

Published: December 2023

As mechanical efficiency has great relevance in the alternative engine performance, the authors research in the development of testing facilities to characterize the sources of engine mechanical losses. The present paper deals with the realization of a hardware platform to conduct experimental studies in small combustion engines to experimentally characterize the mechanical losses of a single-cylinder internal combustion engine by means of the indicated diagram and motoring methods. The system was completed by means of an electrical motor-generator coupled to a single-cylinder air-cooled spark ignition engine, a self-developed electronic hardware control, and a PC-based instrumentation and data acquisition system. Specifications of load-motoring-starting system, including the description of the proprietary electronic load regulation system, are detailed. Also, the instrumentation system of in-cylinder and intake pressures; Temperatures of intake air, exhaust gases, lubricant oil, and engine block; effective torque and crankshaft position are described, including the signal acquisition system. The methodologies for indicated diagram and motoring method are described, mentioning the required measurements to apply each method and the engine load-temperature considerations when an engine is tested in fired or motored conditions. The platform was used to study the mechanical losses of the engine under motored and fired conditions under a wide range of rotational speeds and throttle openings, allowing to draw conclusions about the operating features of the developed test bench in itself, and also about the mechanical losses of the engine tested. Initially, samples of cylinder pressure, torque, intake pressure as function of crank angle and indicate diagram were obtained, showing similar waveforms present in related literature. Then, variations of the aforementioned temperatures against rotation speed and throttle opening and results for the mechanical losses determined by indicated diagram and motoring methods are shown. Finally, two empirical correlations are proposed to estimate the mechanical losses. In the future the hardware platform will be utilized to investigate in-cylinder engine parameters, detailed thermal and mechanical engine performance

Published: December 2023

The extent of existing corn land in Indonesia and the activities carried out by farmers in corn farming requires the innovation of an effective and efficient corn harvesting machine. This underlies the Research Center for Appropriate Technology located at the Faculty of Engineering, Universitas Negeri Padang to design a corn harvesting tractor that can facilitate the community in carrying out activities in the agricultural sector. The design of the corn harvester tractor consists of the harvester mechanism, the frame, the engine, and the powertrain. The frame is a crucial component of the corn harvester tractor, and its strength depends on its shape and proportions. The construction's strength of the frame must take into account both safety considerations and the structure's strength. The purpose of this study is to evaluate the frame strength of a corn harvester tractor made of steel of the ASTM A36 type. In this study, the von Mises stress that exists in the frame is used to calculate the strength of the frame of a corn harvester tractor. In numerical analysis, the chassis utilizes two tests with various load variations, namely the concentrated load and the load that is evenly distributed on the surface. The simulation results show that the frame of the corn harvester tractor can withstand the load well. The results of the stress analysis that occurs on the frame of the corn harvester tractor are that the maximum stress that occurs due to the concentrated load on the frame is 3.248 MPa. While the maximum stress that occurs due to the distributed load acting on the frame is 3.510 MPa. In addition, information was obtained that the value of the safety factor for the frame with ASTM A36 type met the component requirements that could withstand concentrated loads and distributed loads

Published: December 2023

Carp is a type of consumption fish that is much favored by people in Indonesia, because Carp has a lot of protein and meat with good taste. In addition, Carp can be cultivated using tarpaulin ponds, because it saves land and land rental costs. In addition, Carp can be harvested in just 7 months. According to carp cultivators, market demand tends to increase every day, making the need for carp increase and causing Indonesian people to cultivate carp. In this case, it is necessary to apply technology that can help the community in the field of aquaculture, which can be controlled remotely and can monitor the condition of the water in the ponds. The purpose of this study is to find out how pool water filtration works and monitor water conditions using a Total Dissolved Solids (TDS) sensor. The selection of sensor inputs and set point values must be in accordance with the water quality conditions in the Carp pond. The use of the TDS sensor here functions as a detector for turbidity values in Carp ponds that have been set on the NodeMCU ESP32, a submersible water pump as output and the Blynk application as monitoring. The method used, Literature Study, Research Design, Field Study, Functional Testing, Data Processing, Analysis. Because it uses Internet of Thing (IoT) technology in this study, the monitoring and filtering control process can be done anywhere and anytime as long as it is connected to the internet network. From the results of testing the tool on 3 types of water, namely mineral water, clean water, and turbid water, the results for turbid water with 400–600 ppm turned out to be 479 ppm, the value is in the middle between 478 ppm mineral water and 480 ppm clean water. So it can be concluded that this tool works well and can be used in Carp ponds

Published: December 2023

The objects of study are irregular galaxies and the corresponding systems of globular clusters (GCS). The purpose of this article is to compile a list of irregular galaxies containing GCS and find a statistical relationship between the physical parameters. Additionally, let’s aim to develop a method for constructing a non-stationary theory of their origin. It is noteworthy that only a limited number of results from observational data on the study of GCS in irregular galaxies have been published before. It has been identified 23 instances of GCS around irregular galaxies through observations. Based on observational data, lists of irregular galaxies containing the GCS were compiled. Im-type irregular galaxies are found to contain the largest number of GCS. Primarily, GCS are observed in Im-, Sm-, and dIr-type galaxies. The average number of clusters is dominated by Sm-type galaxies. In addition, dwarf irregular galaxies contain few clusters, and the absolute magnitude of their parent galaxies is smaller.

Empirical relationships between the parameters of GCS and their parent galaxies are established. A linear dependence of the logarithm of the number of globular clusters in the system on the absolute magnitude of the host galaxy has been found. The study demonstrates that as the number of globular clusters increases, the mass of the host galaxy shows a linear growth. Additionally, a potential approach to the GCS origin theory has been explored in irregular galaxies by analyzing oscillation modes against the background of the collapse model
Development of environmentally-friendly modified bioadsorbents for water treatment
Authors: Aghahuseynova Minira , Vazirova Leyla
Published: December 2023

As a result of scientific research, it was found that synthesized pure sorbents based on a composite of Fe3O4 nanoparticles and AlgBT have an increased adsorption capacity due to the inclusion of double hydroxides and an alginate matrix. The processes of complex formation occur according to the principle of maximum inheritance of the structural features of the original coordination compounds, which make it possible to predict and implement the hypothetical structures of new compounds. All this significantly improves the adsorption capacity of the developed adsorbents with respect to phosphate ions. Modified sorbents with a clay basis are therefore a particularly intriguing field. The current research constructed and described modified sorbents, and then conducted tests in the laboratory to determine how well they absorbed phosphate. This study used spectroscopic techniques (SEM, FTIR, X-ray diffraction, and XRD analytical methods) to examine the structure and physicochemical characteristics of improved ecologically friendly sorbents based on alginates, bentonite, and nanoparticles. The alginate core may be physically and chemically modified and can take part in a variety of phosphate anion adsorption methods thanks to the active COOH and OH groups that are present there. The sorption efficiency was established for a modified Fe3O4NPs@AlgBT. Equilibrium in the system sorbent-an aqueous solution of Na2HPO4 is established in 10 hours after the start of sorption, while two-thirds of all sobbed anions pass into the solid phase during the first two hours. The limiting sorption of phosphate ions on modified Fe3O4NPs@AlgBT reaches 410 mg/g, which makes it possible to offer it as an effective sorbent for industrial wastewater treatment

Methods: This is a crossover clinical study that included individuals of both genders aged between 20 and 40 years who had had bowel constipation symptoms for over one year. Individuals were randomized into two groups: the intervention (IG) and control (CG) groups. A four weeks washout period was given. Each volunteer underwent 24 individual osteopathic sessions, twice a week that lasted up to 30 minutes. Three intervention techniques were performed: two for the large intestine and one for the small intestine. Results: Thirty four patients were recruited but nine were excluded. Our sample consisted in 25 participants, 13 were allocated in the IG and 12 in the CG. No significant difference was found between groups for anthropometric, educational, marital status, proportion of smokers and alcoholics, and VAS for lumbar spine pain measures. Lumbar spine flexibility, was significant increased for the IG (p<0.0001). A higher proportion of patients in the IG presented reduced hard stools, effort to evacuate, incomplete evacuation feeling, anorectal obstruction sensation and manual maneuvers to facilitate evacuation after treatment (p<0.0001). A significant correlation was found between pain (VAS) and the Schober test (r=-0.41). Conclusion: This study was successful in showing that there seems to be a positive effect of the osteopathic treatment for chronic bowel constipation at short and long terms.
Amor mais que maiúsculo, de Ana Cristina César
Authors: Soletti da Silva Mariana
Published: December 2023

O presente artigo pretende discutir a correspondência de Ana Cristina Cesar a Luiz Augusto Ramalho enquanto estudava em Londres, em 1969. As cartas foram publicadas em Amor mais que maiúsculo, pela Companhia das Letras, em 2022. Serão feitas reflexões sobre as fontes e arquivos literários que possibilitaram a publicação do livro, bem como uma discussão conceitual sobre a correspondência, a autobiografia e as escritas de si contemporâneas. Haverá, também, um olhar para as cartas como documentos históricos e paratextos. Para isso, utilizar-se-á os autores André Luiz Anselm (2015), Philippe Artières (2013), Leonor Arfuch (2010), Michel Foucault (1992), Regina Kohlrausch (2015) e Philippe Lejeune (2014), entre outros. Como resultado, busca-se trazer as cartas como a tentativa de rememoração de um amor em vias de acabar. Ademais, a presença da relação Brasil-Inglaterra e de estrangeirismos na correspondência as transformam em paratexto para os estudiosos da autora.
As cicatrizes da tortura nas memórias de Flávio Tavares
Authors: Gonçalo Fabiana
Published: December 2023

O presente artigo pretende analisar as Memórias do esquecimento de Flávio Tavares, um sobrevivente da ditadura militar brasileira e uruguaia. O envolvimento do jornalista na oposição ao regime lhe trouxe diversas situações-limite, como a prisão, o exílio e, principalmente, a tortura física, descrita em pormenores pelo autor ao longo de sua narrativa traumática. Assim, este estudo busca evidenciar um dos representantes da resistência política, no esforço de ir além do que a história oficial contou, preservando a memória daqueles que reagiram contra a violência de um governo autoritário. Ou, como diz Bungart Neto (2019, p. 68), trata-se de um “antídoto contra o memoricídio coletivo brasileiro”.
O efeito da frequência de formas verbais no ensino e a produção de frases com o verbo Gustar
Authors: De Jesus Souza Lorrainy , Lourenço Cunha Susanna , Ortiz Preuss Elena
Published: December 2023

Este artigo apresenta um estudo que objetiva analisar evidências de efeito de frequência de formas verbais no contexto de ensino formal e a produção de frases com o verbo gustar em espanhol por aprendizes brasileiros. A literatura mostra que, na aprendizagem da segunda língua, os aprendizes transferem estruturas da primeira língua. Porém, quando há distinções estruturais entre essas línguas, eles podem produzir erros, principalmente, ao se tratar de formas pouco ou não ensinadas. É o caso do verbo gustar (em espanhol), que não equivale totalmente, em termos de uso, ao gostar (em português) e, geralmente, é ensinado com a conjugação incompleta. Assim, a hipótese deste estudo é de que a frequência das formas conjugadas no ensino pode contribuir para a eficácia da produção dos aprendizes. Para avaliar essa hipótese, as produções foram divididas em dois grupos, segundo as formas conjugadas do verbo: 1) com formas conjugadas na terceira pessoa (gusta e gustan) que são mais frequentes no ensino; e 2) com formas conjugadas em primeira e segunda pessoa (gusto, gustas, gustáis e gustamos), que são menos frequentes no ensino. Os dados foram obtidos em tarefa de produção de frases, em que se indicava a forma verbal a ser usada em cada frase. Os resultados evidenciaram produções mais rápidas e acuradas com formas verbais mais frequentes (gusta e gustan), sendo significativa estatisticamente a diferença entre os grupos. Isso mostra que pode ser mais vantajoso aos aprendizes quando o contexto de ensino formal inclui todas as formas conjugadas do verbo gustar.
fio da violência conjugal nas narrativas de Mia Couto
Authors: Teixeira da Silva Lima Aline
Published: December 2023

Independentemente da sua roupagem, a violência de gênero expõe o desequilíbrio social da sociedade, demonstrando a relação de poder e de dominação do homem e de submissão da mulher. Dessa forma, o objetivo deste artigo é analisar a representação da violência conjugal na literatura contemporânea, por meio da análise dos contos “Os olhos dos mortos” e “Meia culpa, meia própria culpa”, os quais compõem a obra O fio das miçangas (2004), do escritor moçambicano Mia Couto. Ademais, busca-se compreender e problematizar a representação da dor do outro e do posicionamento das mulheres diante de situações de violência nas narrativas em questão, além de observar os possíveis desfechos trágicos para tais relações abusivas.
caminho da desumanização
Authors: Sereja dos Santos Állan , Guizzo Antonio Rediver
Published: December 2023

No diálogo entre literatura e violência, alguns textos literários proporcionam empatia no leitor diante da violência subjetiva e despertam percepções acerca das formas sistêmicas e simbólicas da violência. Este artigo objetiva analisar no romance Olho de Boto (2015), de Salomão Larêdo, as representações e figurações da violência contra a comunidade LGBTQIA+, as relações com o conservadorismo e autoritarismo contemporâneos e do período da Ditadura Civil-Militar, respectivamente os tempos de produção e representação da obra, e as intertextualidades estabelecidas com a Via Crucis cristã. A narrativa aborda as violências subjetivas, sistêmicas e simbólicas vivenciadas por uma personagem trans que almeja casar-se com o amado e concluir a transição de gênero durante a Ditadura Civil-Militar brasileira. A personagem, vítima da compulsoriedade do modelo cisheteronormativo, somente alcança o objetivo depois da cooptação capitalista deste direito. Os principais aportes teóricos utilizados na análise são Bento (2008), Žižek (2014), Chauí (2017; 2020), Quinalha (2017), Schwarcz (2019).
Condição catastrófica e embriaguez baudelaireana como motivo em Milton Hatoum
Authors: Alvarenga de Sousa Rayniere Felipe
Published: December 2023

Diante da catástrofe na qual Paul Celan (1920 – 1970) esteve exposto, a Primeira Guerra Mundial (1914 – 1918), surgiu um impulsionamento para a sua produção literária. Somado a isso, a partir da noção de exposição ao choque e das contribuições de Charles Baudelaire (1821 – 1867), tenho um insight responsável pela proposição da embriaguez baudelaireana como resposta a eventos traumáticos, sendo uma consequência das experiências sofridas. Assim, evidencio as questões presentes na movimentação dos poetas como motivos de leitura dos romances Cinzas do Norte (2005) e A noite da espera (2017). Ao longo do desenvolvimento do estudo, percebo que essa possibilidade de resposta aos chamados eventos limite pode surgir além dos moldes ditados pela condição catastrófica: como o silenciamento e o apagamento.
intelectual periférico em Paris
Authors: Vilarino Júnior
Published: December 2023

As relações entre trauma, melancolia e criação artística, na autoficção Une Mélancolie Arabe (2008), de Abdellah Taïa, são o pano de fundo da iniciação cinematográfica e literária do protagonista, Abdellah, marroquino domiciliado em Paris. O objetivo deste artigo é evidenciar que esse narrador-personagem, oriundo de um país periférico, ao vivenciar o luto de sua origem e da idealização cultural do país hospedeiro, problematiza uma questão relevante para a literatura comparada, debatendo, durante viagens de retorno a países árabes, a idealização da capital francesa como referência de formação intelectual. A hipótese aventada é que, ao vivenciar rituais iniciáticos, nos quais se imbricam trabalho artístico e interações sociais e eróticas, o narrador vê-se confrontado com a frustração imaginária encarnada pelo corpo e pela língua do outro, terminando por reinventar seu lugar como escritor francófono. O aporte teórico-metodológico constitui-se dos conceitos de melancolia, de Sigmund Freud; não-lugar da literatura, de Eneida Souza; différance, de Jacques Derrida; violência ética, de Judith Butler; e língua menor, de Deleuze e Guattari.
"cultura do estupro" em Aline Bei e Douglas Stuart
Authors: Alves Pinto Jorge , Dias da Silva Antonio de Pádua
Published: December 2023

O texto aborda como dois adolescentes, Mungo (protagonista de Young Mungo) e a anônima (protagonista de O peso do pássaro morto), percebem em si o trauma do estupro sofrido. Ela definha ao longo da vida e morre; ele procura força para resistir à dor da violação e mata os dois estupradores. A “cultura do estupro” como uma prática do machismo viril exige uma constante problematização para que as sociedades herdeiras dessas práticas convivam sem a violência de gênero e não provoquem dor e trauma em pessoas historicamente vulneráveis. Trabalha-se com o conceito de violência, a partir de Freud (2011), Gomes (2013) e Misse (2016), além de masculinidade hegemônica via Connel & Messerchmidt (2013). A literatura busca entabular essa discussão como mais um modo de disseminar o encontro dos gêneros plurais.
epistemologia do armário na obra de Natalia Borges Polesso e Lygia Fagundes Telles:
Authors: Nantes Flávio Adriano , Hatsumi Ana Clara
Published: December 2023

O presente trabalho pretende uma leitura de quatro contos, cujo tema trata das homossexualidades femininas, “Amora”, “As tias”, “Flor flores, ferro retorcido”, do livro Amora (2015), de Natalia Borges Polesso, e “Uma branca sombra pálida”, do livro A noite escura e mais eu (2009), de Lygia Fagundes Telles, a partir do conceito “epistemologia do armário”, proposto por Eve Sedgwick (2007), e seu impacto na vida de quem, deliberadamente ou não, se insurge contra o claustro-armário. Em todos os contos, as personagens lidam com as injúrias e as violências, perpetradas pela sociedade, pelo fato de serem quem são; portanto, ninguém, ao sair do armário, passa incólume aos olhos sociais, sobretudo, aqueles pautados pela estrita “lei” cis-hétero. As obras de Polesso e Telles oferecem ao leitor uma visão do modus vivendi dessas mulheres e a partir destas ficções é possível uma reflexão sobre os eventos factuais no interior da sociedade empírica.
