Authors: Lewkowicz Janina , Tankiewicz-Kwedlo Anna , Pawlak Dariusz , Kiluk Malgorzata , Lagoda Katarzyna , Kowalska Irina
Published: February 2024

Background:Due to their connection to inflammation and oxidative stress, tryptophan metabolites via the kynurenine pathway (KP) relate to important aspects of the pathophysiology of heart failure with preserved ejection fraction (HFpEF) and type 2 diabetes (T2D).
The study aimed to examine the relationship between parameters of HFpEF, measured with transesophageal echocardiography (TTE), and metabolites of the KP.
Methods: One hundred and twenty subjects, 60 with T2D and 60 without, and 55 healthy controls were prospectively included in the current study. Liquid chromatography was used to quantify metabolites of KP in plasma. TTE was performed to assess the systolic and diastolic function of the left ventricle (LV).
Results: Patients with T2D and HFpEF showed an increase in TRP, KYN, and AA concentrations (p=0.001, p<0.0001, p<0.0001, respectively) with a concomitant decrease in 3-HKYN (p=0.0009), and QA (p=0.0029) compared with those with HFpEF without diabetes. There were no significant differences in the morphology of the LV or left atrium, and even the parameters of LV diastolic function were comparable in both subgroups (HFpEF with T2D and HFpEF without T2D). Left ventricular global longitudinal strain (LVGLS) was significantly lower in HFpEF with T2D than in the subgroup of HFpEF patients without T2D (p=0.0026).
Conclusion: Plasma levels of the kynurenine pathway metabolites were elevated in patients with HFpEF, and especially in patients with HFpEF and T2D. An increase in KP plasma metabolite concentrations were associated with LV remodeling and diastolic dysfunction.
On the geometry of diffeological vector pseudo-bundles and infinite dimensional vector bundles: automorphisms, connections and covariant derivatives
Authors: Magnot Jean-Pierre
Published: February 2024

We consider here the category of diffeological vector pseudo-bundles, and study a possible extension of classical differential geometric tools on finite dimensional vector bundles, namely, the group of automorphisms, the frame bundle, the space of connection 1-forms and the space of covariant derivatives. Substential distinctions are highlighted in this generalized framework, among which the non-isomorphism between connection 1-forms and covariant derivatives. Applications not only include finite dimensional examples with singularities, but also infinite dimensional vector bundles.
Transit-Oriented Development Typology in Middle East's Metropolitan Context: Iran as a Case Study
Authors: Abkooh Shirin Sabaghi , Rahnama Mohammad Rahim
Published: February 2024

Recently, there has been a growing global interest in typology as an effective mechanism for streamlining contextual complexities and facilitating the implementation of Transit-Oriented Development (TOD), particularly in the vicinity of rail transportation systems. However, despite the precedence set by early adopters in the field of TOD, countries in the Middle East as newcomers lack comprehensive typological studies. Addressing this research gap, this paper endeavors to devise a TOD typology tailored to the geographical area encompassing a 400-meter radius around 33 active metro stations in Mashhad, Iran. Employing a systematic approach, the study constructs a spatial model integrating the 6D model (encompassing destination, distance, density, diversity, design, and demand management) alongside the k-means cluster analysis technique, thus contributing methodologically to the advancement of TOD typological methodologies. The findings delineate five discernible TOD archetypes, namely “urban neighborhoods,” “city commercial centers,” “specialized healthcare activity centers,” “recreational-educational activity centers,” and “transit centers.” Notably, the station areas categorized as “city commercial centers” exhibit the highest prevalence rate (78.78%). Nonetheless, the identification of the remaining four types bears significance, with the study notably introducing two novel typologies to the extant literature, namely the “specialized healthcare activity center” and the “recreational-educational activity center”, which hold applicability beyond the Iranian context. This research underscores the relevance of TOD typologies in informing urban development strategies and offers insights pertinent to transit-oriented planning endeavors.

Published: February 2024

Sweeping using brushes in curling games is widely performed not only to extend the stone-stopping range but also to control curls, although little scientific evidence supports the curl-controlling effects. In this study, we performed a measurement to examine the effects by developing a stone-shooting machine-SSM-I. Additionally, a simple method for measuring friction in split time is proposed. The results suggested the positive effects of left-right asymmetric sweeping with 95% reliability for sweeping on the opposite half-side to assist curling. We also confirmed the effect of stopping-range extension with 99% reliability. Along with stone checking and inspecting their bottom roughness, SSM-I can assist in assessing the friction conditions of ice.
Effect of Axial Bruxism Bite Force on Titanium Alloys Biomaterials Experimental Chewing Test and 3D Finite Element Simulation
Authors: YILMAZ Efe Cetin
Published: February 2024

Bruxism can be defined as the process of direct contact with teeth and dental materials with an involuntary jaw-tightening movement. In this process, teeth and dental materials can be exposed to various damage mechanisms. This study aims to analyze the wear behavior of cp-Ti, Ti-5Zr, and Ti-5Ta alloys, which are frequently preferred as dental materials in the human body, under different Bruxism wear processes by experimental in vitro chewing cycle and finite element analysis simulation method. Cp-Ti and titanium alloy test specimens with cylindrical geometry were exposed to a direct every-contact wear mechanism for 30 seconds under 100N bruxism chewing bite force. The bruxism chewing cycle continued for 300 minutes at a frequency of 1.8 Hz. Microanalysis of the wear surfaces of the samples after the experimental study was carried out with Scanning Electron Microscopy(SEM). The Bruxism wear volume loss that occurred in the wear area of the test specimens was measured with a 3D non-contact profilometer. The results obtained within the scope of this study showed that the Bruxism wear resistance increased by adding zirconium and tantalum to pure titanium material. In axial Bruxism bite forces, the least wear volume loss occurred at 90° bite forces chewing process. However, in the Finite Element Analysis simulation, it was observed that the maximum stress area was evident in the implant structure at 75° bite force chewing process. This will make it difficult for the implant to osseointegration within the body and will cause various damage mechanisms to the integrity of the implant.
Perineural invasion on prostate cancer is associated with Schwann cells and circadian rhythm-related genes disruption: a bioinformatics approach
Authors: Silva Sérgio Lopes , Neta Genilda Castro Omena , Rocha Rodger Marcel Lima , Duarte Ana Kelly da Silva Fernandes , Fraga Carlos Alberto de Carvalho
Published: February 2024

Studies have shown that Schwann cells participate in the tumor microenvironment, producing several factors that benefit cancer cells. During this process, Schwann cells are dedifferentiated and help the process of cancer cellular proliferation. These cells then migrate to the region close to the tumor tissue and assist the development of the neoplastic cell. In this context, the present study aimed to evaluate the influence of Schwann cells on prostate cancers. We investigated the association between Schwann cells and prostate cancer often associated with perineural invasion. Initially, we used the GEO Datasets platform from the GEO repository to identify a database reporting gene expression in Schwann cells in a neoplastic context. Briefly, the database contains the expression results from experiments in which two factors produced by tumor cells were added to cell cultures. Comparisons were made between samples from the first and third passages. We then used these data to perform differential gene expression analysis and crossed data from upregulated genes with differential expression data from negative and positive perineural invasion prostate cancers. We observed that the “axon guidance” pathway was upregulated in negative perineural invasion prostate cancers. Meanwhile, upregulated mRNAs activate the “axon guidance” and, together with ROBO1 and MPZ upregulation, inhibit perineural invasion pathways. Both genes are also associated with Schwann cell migration inhibition. PER3, NR3C1, PPARGC1A, TIMP3, ID2, PDE6B, and CAVIN1 were upregulated in negative perineural tumors, while SLC25A10 was upregulated. We also observed upregulated genes in positive perineural invasion: PPARGC1A, TIMP3, S100A8, ID2, DEFB1, AQP3, ASS1, PDE6B, NEFH, and CAVIN1. AQP3 and NEFH were upregulated only in positive perineural invasion tumors and PER3 and NR3C1 were upregulated only in negative perineural invasion samples. We believe that Circadian rhythm and/or melatonin disruption could be associated with Schwann cells dedifferentiation; consequently, Schwann cells produce different factors that will participate in various processes of tumor progression. These processes may also be involved in tumor invasion into the perineural tissue in prostate cancer.

Melatonin plays an important role in the regulation of circadian clock genes, whose deregulation contributes to cancer development. In this study, we first performed a bioinformatic analysis for melanoma, non-melanoma skin cancer, and oral squamous cell carcinoma to evaluate what clock-related genes are deregulated when compared to normal tissue. Further, we administrated melatonin in cell cultures for cutaneous squamous cell carcinoma, skin melanoma, and oral squamous cell carcinoma to observe changes in cancer cell phenotypes. Later, we evaluated gene expressions associated to clock genes, cancer cell proliferation, migration, invasion, and apoptosis. In summary, clock-related genes are deregulated in both cancers. Skin melanoma and oral cancer presented commonly deregulated clock related genes and were associated with poor survival and chemoresistance, according to bioinformatic analysis. In cell culture, melatonin administration increased Per2, Cry1, Cry2 and Bmal1 mRNA expression levels and decreased Clock gene mRNA levels. Per2, Cry1, Cry2, and Bmal1 genes belong to tumor suppressor genes that can control cell proliferation, cell death, DNA damage, and repair system. Te hypothesized that changes in the expression of clock related-genes in cancer could be responsible for metabolic changes that could lead to the cancer aggressiveness. Melatonin administration showed changes in melanoma and oral cancer phenotypes. Melatonin also seems to influence melanoma and oral tumor progression through Mki67, Hif-1a, Vegfa, Col1a1, Cdh1, Casp3, Bax, Bcl2, Mmp9, Per2, Cry1, Cry2, Bmal1 and Clock modulation.
Concept of mental fatigue in lay people: a survey-based examination using situational vignettes
Authors: Csathó Árpád , Simon Eszter , Linden Dimitri , Matuz András
Published: February 2024

Background.
Mental fatigue is a common subjective experience, often caused by prolonged mental workload. While there are several scientific theories about the nature of fatigue and its causes, no previous studies have examined laypeople’s opinions on what task characteristics they consider as main causes of mental fatigue. Therefore, this study explores laypeople's concepts of fatigue using situational vignettes.
Methods. Participants read descriptions of administrative tasks with low (n = 212) or high workload (n = 177) and rated 1) which general task characteristics are involved, and 2) which task characteristics most likely cause fatigue. Participants’ mood states were also assessed, namely anxiety, depression, and fatigue catastrophizing. Mixed-ANOVA, robust regression, and exploratory factor analysis were used to analyse the data.
Results and Conclusion. The analyses revealed significant links between fatigue and task characteristics, indicating that underload (e.g. boredom) as well as overload (e.g. energy demand) were considered particularly fatiguing. On the one hand, fatigue was associated with feeling of boredom, drowsiness or discouraging experienced during a prolonged task, and on the other hand, with the difficulty, the energetic demand of the task. In general, the results suggest that non-scientific opinions are diverse regarding the potential causes of fatigue.

Published: February 2024

Background
Worldwide, the Joint Monitoring Program reports that one in four health care facilities (HCFs) lack functional water supply on premises, one in three lack hand hygiene facilities, and one in three lack adequate infectious waste disposal. The COVID-19 pandemics shed light on the lack of investments, the absence of infrastructures, education and policies related to WASH as well as revealed insufficient investment in healthcare safety; and has brought WASH services as non-negotiable for HCFs.
Methods
This study used a cross-sectional pre-post COVID-19 framework to determine the proportion of HCFs: meeting basic WASH services and, which WASH services improved post-COVID-19 in the Far-North Region of Cameroon.
Results
A total of 97 (23.04%) HCFs among the 421 that are found in the Far-North region were surveyed and located in eight (25%) of the 32 Health Districts. They corresponded to the integrated health centers category (79.4%) and the survey’s respondent was the chief of the HCF (92.8%). Approximately 75.3%, 0.0%, 48.5%, 46.4%, and 6.2% of HCFs respectively met thresholds for basic water, sanitation, hygiene, waste management, and environment cleaning services. When comparing pre- vs. post COVID-19 periods, a significant increase (8%) was noted in the proportion of HCFs as of optimal handwashing practices-related services (P = 0.0026). There was also a significant increase (p = 0.007) in the proportion of HCFs with cleaning protocols available. Further, none of the HCFs fulfilled all the criteria to meet basic services for all the five WASH services.
Conclusions
In conclusion, the response to the COVID-19 pandemics only partially improved WASH services-related infrastructures in HCFs of the Far-North Region of Cameroon. The COVID-19 pandemics was a missed opportunity to strengthen WASH services. There should be a continuing encouragement of governments and funding agencies in planning and budgeting WASH in healthcare-related research and issues, and enabling the maintenance of existing WASH infrastructures in healthcare settings.
Geographic region and health outcomes: Examining health determinants and outcomes of older adults across Ghana’s North‒South divide
Authors: Kodwo-Nyameazea Yale , Amponsah Nana-Akua
Published: February 2024

Healthcare services and outcomes are often not evenly distributed across geographic regions. This study used the harmonized Research on Early Life and Aging Trends and Effects (RELATE) dataset to compare health outcomes across the North‒South divide of Ghana and determine the factors underlying the difference in health outcomes. Although the literature indicates that the South has more health resources and better health indicators, the study found that health outcomes in the North were comparatively better than those in the South. According to the optimal health index scores, people in the North are living at 86 percent of their optimal health, while 82 percent are living at their optimal health in the South. In both regions, optimal health was substantially influenced by work-related physical activity and age. Older adults whose work involved vigorous activities had better health outcomes, but health outcomes decreased as people aged. The study also revealed that healthcare use and sex influence health outcomes, particularly in the southern region. The results showed that older adult women in the South have poorer health outcomes than their male counterparts. It has also been shown that older adults in the South are more likely to contact health professionals for medical conditions.
Risk factors and management of urinary tract infections among pregnant women attending antenatal care at Jazira Specialist Hospital in Mogadishu, Somalia: A cross-sectional study
Authors: Jayte Mohamed
Published: February 2024

Background
Urinary tract infections (UTIs) are associated with adverse pregnancy outcomes if left untreated. Data on UTI burden and associated risk factors among pregnant women in Somalia is limited.
Methods
A hospital-based cross-sectional study was conducted between June-December 2020. A systematic random sampling technique was used to enroll 392 pregnant women. Data was collected via interviews and medical record review. Multivariable logistic regression was performed to identify independent risk factors.
Results
The reported UTI prevalence was 38.3%. Factors independently associated with UTIs included: low education level (AOR 2.1, 95% CI 1.3–3.4), handwashing < 5 times/day (AOR 1.8, 95% CI 1.1–2.9), and prior UTI history (AOR 2.5, 95% CI 1.6–3.9). The majority (63.8%) reported ‘good’ household hygiene. Of those using medications during pregnancy, 38.3% used drugs and 13.3% received antibiotics.
Conclusion
Targeted interventions are needed focused on women’s empowerment and hygiene promotion, antibiotic stewardship, and developing clinical guidelines to reduce UTI burden in this setting. Further research is warranted to address barriers to optimal management.

The present work investigates whether financial abilities can be associated with numerical abilities and with general cognitive abilities. We compared performance on numerical and financial tests, and on tests routinely used to measure general cognitive performance, in healthy controls and in a group of people with heterogeneous pathological conditions including mild cognitive impairment, amyotrophic lateral sclerosis, traumatic brain injury, and schizophrenia. Patients showed lower performances in both numerical and financial abilities compared to controls. Numerical and financial skills were positively correlated in both groups, but they correlated poorly with measures of general cognitive functioning. Crucially, only basic financial tasks -such as counting currencies- but not advanced ones -like financial judgments- were associated with numerical or general cognitive functioning in logistic regression analyses. Conversely, advanced financial abilities, but not basic ones, were associated with abstract reasoning. At a qualitative analysis, we found that deficits in numerical and financial abilities might double dissociate. Similarly, we observed double dissociations between difficulties in financial abilities and cognitive deficits. In conclusion, financial abilities may be independent of numerical skills, and financial deficits are not always related to the presence of cognitive difficulties. These findings are important for both clinical and legal practice.

Published: February 2024

The active pharmaceutical components of Propranolol and Hydrochlorothiazide in their bulk dosage forms were to be measured using a unique, straightforward, responsive, and stable RP- HPLC method that was being developed and gradually validated. For the quantitative determination of Propranolol and Hydrochlorothiazide, a straightforward, specific, verified, and well-defined stability that exhibits gradient RP-HPLC approach has been developed. The Waters C18 column (150mm×4.6mm, 5mm particle size) was used for the chromatographic method, which involved isocratic elution with a mobile phase made up of orthophosphoric acid (0.1%) and acetonitrile (40:60% v/v). The instrument parameters called for a flow rate of 1 ml/min and a detection wavelength of 265 nm using the UV detector. The chromatographic method was expedited using the impurity-spiked solution. The proposed method's validity was examined in accordance with the international conference on harmonization (ICH) guidelines. The plotted calibration charts had linear regression coefficients of 0.999, indicating that their linearity was within acceptable bounds. The suggested approach is quick, easy, practical, and reasonably priced. It can be used for routine manufacturing sample analysis during stability tests and to confirm the caliber of medication samples during stability studies.

Published: February 2024

Rockwool and peatmoss are commonly used substrates in the greenhouse industry due to their quality, stable pH, exceptional water retention properties and air porosity that is important for plant root development. Although rockwool is commonly used in deep water culture (DWC) hydroponic systems as the base support, there is a lack of studies comparing different types of substrates that could be used in DWC systems, especially considering the increasing market value and awareness of sustainable production in controlled environment agriculture. We identified 13 commercial substrate mixes with different compositions and conducted a series of studies in a DWC system in a greenhouse for three seasons to evaluate their effects on arugula ‘Slow Bolt’ (Eruca sativa L.) and lettuce ‘Summer Crisp’ (Lactuca sativa L.) growth, yield, and quality. The substrates tested significantly influenced the growth, yield, and quality of both arugula and lettuce. The average leaf fresh weight per plant could range from 44 to 190 g for arugula and 89 to 265 g for lettuce. The peat-based products outperformed the coir and other inorganic substrates (phenolic foam, rockwool). The substrate with 75% peat + 25% fine coir produced the greatest plant height, width, and biomass for arugula and lettuce over three growing seasons. Examining arugula and lettuce growth, the fall season produced plants with higher water and nutrient use efficiency, while plants grown during the winter had lower resource use efficiency. Further research is needed to engineer hydroponic substrates suitable for various seasons of leafy green production that results in comparable yield and quality.
Low-temperature crystallization of kumdykolite, a polymorph of albite, during mineral carbonation within fluid inclusions in hornblendite from the Dabie orogen, central China
Authors: Zhang Long , Wang Qiang , Xian Haiyang , Ding Xing , Li Wan-Cai , Yang Yiping
Published: February 2024

Kumdykolite is a polymorph of albite that has been predominantly identified within crystallized melt inclusions in high-temperature metamorphic rocks. This study reports a new occurrence of kumdykolite that formed during internal mineral carbonation within amphibole-hosted fluid inclusions in post-collisional hornblendite from the Dabie orogen, central China. Amphibole in the hornblendite trapped CO2-rich fluid inclusions at the magmatic stage, and mineral carbonation, referring to the reaction of mineral rich in divalent cations and CO2 into carbonate, occurred in situ within the fluid inclusions due to the interaction between trapped CO2-rich fluids and host amphibole during cooling of the hornblendite. Kumdykolite was produced along with calcite, dolomite, chlorite, talc, a SiO2 phase (quartz or cristobalite), a TiO2 phase (rutile or anatase), and mica during internal mineral carbonation within the fluid inclusions. It is estimated that kumdykolite in the fluid inclusions crystallized under near-surface conditions, which are significantly different from the conditions of crystallization proposed in previous studies. It is further inferred that kumdykolite may crystallize metastably across the stability field of albite, and the presence of kumdykolite is not indicative of extreme thermobaric and fluid-absent conditions.

Published: February 2024

The aim of the present study was to evaluate the influence of slow, controlled breathing exercises (SCBE) on arterial pressure and autonomic cardiac modulation in hypertensive patients. 29 hypertensive patients were evaluation in two data collections (period between 1 to 3 days). In each evaluation, data were collected after 10 min of spontaneous breathing (between 12 and 20 breaths per minute – bpm) and 10 min of SCBE (12 bpm, in the rhythm of standardized verbal stimulus). The arterial pressure was evaluated by a multi-parameter monitor and the autonomic cardiac modulation by the rate variability technique. The SCBE reduced systolic arterial pressure (1st evaluation: -4.8 mmHg and 2nd evaluation: -4.3 mmHg), decreased sympathetic activity by 18% and modified autonomic modulation by about 50%. SCBE reduced both systolic arterial pressure and sympathetic activity and can be used in control arterial pressure of hypertensive patients.

To verify the association between community food environment and Body Mass Index (BMI) of adults. Systematic review conducted in EMBASE, PubMed, and Web of Science databases, considering the period from 2010 to 2022. Out of 10,407 articles, 24 observational studies were eligible according to the inclusion criteria. The methodological approaches were evaluated using STROBE (Strengthening the Reporting of Observational Studies in Epidemiology) and OSQE (Observational Study Quality Evaluation). The protocol was registered at PROSPERO (number 42021260594). Most studies reported that BMI tends to increase with proximity to and a greater number of supermarkets, fast-food establishments, and convenience stores. The prevalence of adults with BMI greater than 25 kg/m2 was higher in locations with lower socioeconomic status. BMI was lower in more financially advantaged neighborhoods near grocery stores and fruit and vegetable markets. The selected studies indicate that a community food environment with higher availability of unhealthy foods is related to high BMI. The socioeconomic level can worsen this association, showing that people in social vulnerability have more difficulty accessing healthy food.

Authors: Ni Hongmei , Yin Xupeng
Published: February 2024

This article investigated the construction conditions of the pile foundation in the Wuxing section of the “Shanghai Suzhou Huzhou” railway bridge project. To test the reliability of large diameter connectors, it has established a finite element model with ABAQUS software for numerical simulation. Based on on-site tests, the reliability of the connection between the pipe pile and the cover steel was studied. According to the simulation results, when the load is P= 900 kN, the displacements of A2 and A3 steel pipe piles are 55.8 mm and 60.1 mm, respectively. The load-displacement relationship shows a high-order curve distribution. According to the results of on-site experiments, the displacements are 77.9 mm and 60.2 mm, respectively. The load-displacement relationship is linear. The results for the simulation and on-site testing are consistent. This study provides a basis to the research on the reliability of the connection between large-diameter steel pipe piles.

Authors: Shen Bao-Shan , Zhang Mei-Juan , Jin Jun-Jun
Published: February 2024

In order to improve the vibration isolation, environmental adaptability and development efficiency of rubber mounts, a novel rubber mount with adjustable parameters such as stiffness, support height and limit distance was proposed, and its structural composition and working principle were described. And then, a commercial vehicle was taken as the research object to conduct the calculation of mounts stiffness by employing the energy decoupling method and genetic algorithm. On the basis of the influence of cone angle, thickness and height on the ratio of axial-radial stiffness, the detailed structural design of the mounts was carried out, and the relationship between the preloading displacement and axial-radial stiffness was studied by the method of theoretical calculation and test, which made the process of the stiffness adjustment more specific and accurate. Finally, the vibration isolation performance test of the Powertrain Mounting System (PMS) before and after stiffness adjustment was completed. Results show that the adjusted PMS indicates better vibration isolation performance at idle speed and slow acceleration in place, and the new mounts can effectively improve the vibration performance of vehicle, environmental adaptability of mounts and product development efficiency.

Through a series of static mechanical tests and (SHPB) dynamic impact tests, the static and dynamic mechanical parameters of rock as represented by yellow sandstone are determined, and the Holmquist-Johnson-Cook model parameters of the rock are calibrated using the test data and theoretical calculations. The feasibility of a numerical model is verified, and numerical analysis of the SHPB impact process under different radial pressure pre-loading is carried out on the basis of good verification. The results show that with increasing impact load, the degree of rock breakage increases, as does the dynamic tensile strength. With the application of increasing pre-static pressure, the dynamic tensile strength of the rock decreases gradually, and the maximum radial cumulative strain increases continuously under a given impact pressure, indicating that micro-cracks in the rock develop initially and then expand under the influence of pre-static pressure; the rock is more easily broken, and its weakening degree increases. Under coupled dynamic and static loading, the energy utilization rate of rock in the Brazilian splitting process is jointly affected by axial compression ratio and impact load. Too large a pressure ratio will reduce the strain-rate sensitivity of rock, resulting in low energy utilization rate, while too low an axial compression ratio will make the dynamic tensile strength of rock relatively high, which is not conducive to tensile failure. Therefore, on the premise of clear fracture form requirements, a suitable combination of axial compression ratio and impact velocity can improve the rock crushing effect and energy utilization rate.

Methane (CH4) and carbon dioxide (CO2) emissions from tropical freshwater ecosystems have been understudied, particularly in terms of their interaction with limnological dynamics, their cycling, and the emission mechanisms of CH4. To help reduce that knowledge gap, this study addressed these processes in Valle de Bravo (VB), a tropical (19° 11. 65′ N) reservoir lake, that provides water supply to Mexico City metropolitan area. CH4 and CO2 concentrations and emissions from VB were measured during four field campaigns distributed along the annual limnological cycle of the reservoir. Dissolved CH4 concentration varied over four orders of magnitude (0.015–176.808 μmol L−1), and dissolved CO2 varied from below atmospheric saturation (15.062 μmol L−1) to 10 times that concentration (219.505 μmol L−1). CH4 fluxes ranged from 23.25 to 1220.80 μmol m−2 day−1, while CO2 fluxes ranged from −60.11 to 254.99 mmol m−2 day−1. Seasonal monitoring also allowed the assessment of the annual emissions as well as the greenhouse gas (GHG) storage during thermal stratification, which accounted for >58% of the total GHG annual emissions from VB. Overall, VB is a source of GHG, and its major contribution is the CH4 released during the autumn overturn.
EXPERIÊNCIA E POBREZA
Authors: DOS SANTOS MAURICIO INACIO
Published: February 2024

A busca por compreender o sentido de experiência na vida humana marcou os escritos de Walter Benjamin. Sua obra é perpassada por essa busca e pela compreensão do seu empobrecimento na modernidade, a partir dos diversos inventos, técnicas e tecnologias que mudaram radicalmente a existência do indivíduo em sociedade. Experiência e pobreza: um olhar para realidade a partir de Walter Benjamin é uma reflexão sobre o empobrecimento do sentido experiência em nossos dias, considerando o olhar benjaminiano. O objetivo deste artigo é discutir, em breves palavras, como o conceito e reflexão sobre experiência e sobretudo o seu empobrecimento é ainda importante e capaz de ajudar na compreensão de nossa realidade. Trata-se de uma proposta de reflexão dos textos de Benjamin que tratam do tema experiência, sobretudo “Sobre o programa de filosofia do por vir” e “Experiência e Pobreza”, tomando como referência a discussão entre vivência e experiência, ambas capturadas pela sociedade capitalista, tornando-se empobrecida e desconectada da realidade. Resgatar o verdadeiro sentido de experiência que possa nortear a existência humana é um imperativo que se impõe. Como superar a mecanização da vida impetrada pela tecnologia é questão que se apresenta na tentativa não de negação da tecnologia, mas de uma reflexão crítica de suas influências subjetivas no indivíduo e em uma sociedade movidos pelo excesso de informação e tecnologia. Buscar o sentido da experiência, na perspectiva benjaminiana, pode ser um caminho de reconstrução do ser humano tão danificado e diminuído em uma sociedade que primou demasiadamente pela razão e pela técnica.
discursivização do MST no discurso midiático

No Brasil, o campo tem sido palco de uma luta desigual e, muitas vezes, sangrenta, entre trabalhadores e proprietários rurais. Como essa luta é travada entre classes antagônicas, muitos e divergentes são os sentidos produzidos sobre a atuação do Movimento dos Trabalhadores Rurais Sem-Terra (MST). Assim, o objetivo deste trabalho é analisar o funcionamento da memória discursiva sobre o MST no discurso das revistas Veja e Carta Capital, edição online, com base na Análise do Discurso de viés pecheutiano (PÊCHEUX, 2009; 1999). Para tanto, analisamos manchetes extraídas das referidas revistas, observando o modo como o MST é discursivizado nestes dois lugares de memória.
Nas trilhas do discurso
Authors: Rodrigues Anderson Lins , Xavier Manassés Morais
Published: February 2024

Este artigo tem por objetivo discutir algumas especificidades do arcabouço teórico de duas vertentes de análise do discurso: a perspectiva denominada Análise Dialógica do Discurso (ADD), situada a partir das ideias de Bakhtin/Voloshinov e a Análise do Discurso, cuja orientação advém das reflexões de Michel Pêcheux – AD pecheuxtiana, com fulcro na ideologia como constitutiva dos sujeitos e dos sentidos. Para consecução desse objetivo, faremos o contraponto de alguns de seus pressupostos, como as noções de língua, discurso, signo, ideologia, indivíduo social/sujeito e sentido (efeito de) sentido, com os postulados de Ferdinand Saussure, bem como tentaremos estabelecer um diálogo/duelo entre as ideias defendidas pelas duas vertentes.
construção da brasilidade inscrita em anúncios impresso e televisivo das sandálias Havaianas
Authors: Carvalho Cid Ivan da Costa
Published: February 2024

Este trabalho se propõe a analisar os efeitos discursivos da brasilidade nos anúncios publicitários impresso e televisivo das sandálias Havaianas, entrevendo as relações entre a construção desse tipo de anúncio na constituição da identidade nacional. Para isso, utilizamos dois passos fundamentais: o estudo bibliográfico em autores da Análise do Discurso, como: Pêcheux (2007), Orlandi (2003), Foucault (2004) e com Hall (2005) estudioso da cultura moderna e a pesquisa no site das sandálias Havaianas um comercial televisivo e um anúncio impresso publicado na revista. Os anúncios publicitários das sandálias Havaianas exploram o sentido do uso tradição de que o Brasil é o melhor lugar do mundo para viver, associando a brasilidade ao produto e fazendo com que as Havaianas sejam reconhecidas como sinônimo de ser brasileiro.
VOZES MULHERES:

Published: February 2024

Considerando a importância da Lei 10.639/03, sancionada em 2003, que torna obrigatório o ensino e o debate sobre a cultura, a história e a literatura afrodescendente nas escolas de base, este relato intenta descrever a experiência exitosa de um projeto de literatura pautado na referida lei, partindo da mediação de leituras, no ensino médio, numa escola pública estadual do Ceará. O projeto Vozes Mulheres teve como aporte teórico os conceitos de interseccionalidade defendidos pelas pesquisadoras Angela Davis, Carla Akotirene, bell hooks, entre outras, bem como a definição de lugar de fala argumentado pela filósofa Djamila Ribeiro. Dessa forma, este relato de experiência apresenta como a obra Olhos d´água, da autora afro-brasileira Conceição Evaristo, foi trabalhada em sala de aula a partir das práticas de multiletramento, releituras e multimodalização do gênero conto, promovendo importantes debates acerca da identidade sociocultural da comunidade escolar, além do despertar crítico conceitual do que significa pertencimento, alteridade, afroestima e o diálogo entre gênero, raça e classe. Portanto, o Vozes Mulheres mostra como a literatura afro-brasileira, contemporânea, rompe com os clássicos canônicos e quebra paradigmas de que o público leitor jovem não lê, ao contrário, a escola e o incentivo à leitura mostram-se como um espaço de afeto e acolhimento para a juventude periférica multirracial e plural.
A ARGUMENTAÇÃO DISCURSIVA COMO FERRAMENTA DE CONVENCIMENTO E PERSUASÃO NA REDE MUNDIAL DE COMPUTADORES
Authors: FÁBIO PEIXOTO DE ARAUJO ANDRADE DA SILVA MARCELO
Published: February 2024

É sabido que a rede mundial de computadores tem sido uma ferramenta de grande importância no que diz respeito à comunicação e, consequentemente, à interação social entre humanos. Na atualidade, por estar presente em boa parte dos lares brasileiros, a internet é um meio utilizado não apenas para comunicação entre pessoas que outrora estavam distantes, fisicamente falando, mas também como um meio para realizar negócios. Dessa maneira, verificamos que a cidade de São Luís entra numa ordem discursiva voltada para o capital e não apenas isso, que a sua Prefeitura Municipal se vale de todo um discurso pautado na diversidade cultural encontrada na localidade para atrair turistas. O presente estudo tem por objetivo principal analisar, pelo viés argumentativo do discurso, mais especificamente a partir dos postulados de Perelman e Olbrechts-Tyteca (2005), alguns recursos argumentativos utilizados por essa instância do poder a fim de atrair turistas-internautas de toda parte do Brasil e também do mundo. Nossa pesquisa aponta que os argumentos mais utilizados pela Prefeitura de São Luís são do tipo baseado na estrutura do real, por serem aqueles que mais se aproximam da realidade, de acordo com a taxinomia desenvolvida pelos teóricos citados acima.
ARQUEOLOGIA E VIDA: UM DEBATE COM FOUCAULT E JACOB
Authors: De carvalho Pereira Anderson
Published: February 2024

Este artigo mostra que a obra A Lógica da Vida de François Jacob pode ser lida conforme uma linguagem arqueológica, no sentido dado por Foucault em A Arqueologia do saber. Para isto, a partir da noção de enunciado em Foucault, foram destacados dois enunciados que serviram de marco para a definição destes campos e suas rupturas: o valor funcional das espécies e a individualização. Este diálogo também foi realizado ao se detectar a finidade entre a reflexão sobre a epistemologia da ciência estabelecida por Foucault em As palavras e as coisas e o debate sobre linguagem e biologia molecular visto em Jacob. Os recortes retirados desta última obra para mostrar esta afinidade foram eleitos e analisados sob uma vertente da arqueologia foucaultiana. Por meio deste argumento, foi destacada a contribuição que Jacob teve para decifrar uma lógica arqueológica do invisível da ciência moderna.
