Published: October 2023

Research into children’s meaning-making of climate change reveals muddled notions about the scientific explanations, a limited understanding of the impacts and redressal measures and high levels of climate anxiety. Children learn about climate change through informal networks, social media and school. Formal teaching about climate change has predominantly used the positivist approach which has focused on the scientific causes and consequences of climate change to the exclusion of the socio-political-cultural and normative dimensions. Education programs based on constructivist pedagogy have demonstrated positive impacts on climate literacy and climate anxiety. Similarly, programs designed using critical pedagogy have helped engender sympathy and an understanding of climate justice. However, little is known about the combined impact of such programs especially on children in the global south. This Qualitative Experimental research highlights the shift in 18 Indian middle and high-school children’s meaning-making during a climate change education program based on Project Based Learning & Critical Pedagogy. Template analysis of pretest & posttest questionnaires, reflections, interviews and child-authored storybooks was used. The study revealed an improvement in climate literacy, a sense of ‘pragmatic hopelessness’, and a profound sense of empathy with the marginalized in their city among the children. Given the children’s overwhelming expressions of solidarity with the marginalized, we propose a framework for climate education which intentionally foregrounds teaching of climate justice and focuses on emotional rather than knowledge based understanding. This framework could be applied in other contexts and geographies.

Published: October 2023

When researchers want to understand differences in personal culture---a person's attitudes, beliefs, values, and practices--how much attention should they pay to adult experience? Recent work has reached substantially different conclusions on this question. We argue that this disagreement is an unintended consequence of the "tournament of models" approach researchers have used, which focuses on whether people change and not how much they change. To advance the theoretical debate, we refocus attention on the relative importance of personal change over time for explaining differences between people. We introduce a new measure for quantifying the proportion of systematic variance in panel data attributable to intrapersonal change. Applying this measure to 609 items from seven surveys in five countries, we find that although intrapersonal change is common, it is generally small in magnitude. As an extension of the theoretical debate, we demonstrate that this measure provides new insights when comparing social groups, showing that intrapersonal change is less common among U.S. college graduates than among those without a college degree. Our findings provide a new perspective on several important theoretical debates, as well as a tool to address new questions.
Advaita Interpretations of Yogi Narayana of Kaiwar: Exploring the Concept of Jivanmukti in Kala Gyana*

Published: October 2023

This paper expounds an advaitic interpretation of the concepts of jivamukti, in the context of kalagyana, of Sri yogi narayana of kaiwar. The temporal knowledge analogous to Tibetan kalachakra tantra of the Vajrayana, is a unique temporal knowledge of the interplay of light and shadows, in an advistic interpretation of life as an interference of sunlight and water, as creating that vast spectrum of life symbolized by the Adityas and Vishnu.Keywords: Advaith, avaduta, jivamukti, Adityas, Vishnu

Soybean holds a leading position in the world ranking of the agricultural crops. The cultivated areas for this crop have been expanding in all countries of the global leaders in its production. In Kazakhstan, in recent years the cultivated areas have decreased from 139.5 thousand hectares in 2019 to 113.3 thousand hectares in 2021. This is due to the difficulty to grow the early-season varieties in the northern region of the Republic. The average crop yield of soybean by region ranges from 3.0 c/ha in the north to 24.8 c/ha in southeastern Kazakhstan. The crop yield of the developed and approved for production varieties can be increased by the additional agronomic techniques, including the pre-sowing seed treatment with the biologically active substances. This paper demonstrates the results of the effect of soybean seed treatment for different groups of maturity with the nitrogen-fixing inoculant HiStick and micronutrients of Co and Mo. Profitability of the conducted treatments was calculated. The pre-sowing treatment with salts of molybdenum and cobalt is profitable to use for early-season variety Ivushka and full-season variety Lastochka. For the early ripening variety Birlik KV, the highest profitability was observed for the combined seed treatment with nitrogen-fixing inoculant HiStick and salts of Mo and Co. In Zhansaya soybean variety, the application of the additional treatments decreases the profitability of production.

OBJECTIVE

Radiofrequency thalamotomy (RF-T) is an established treatment for refractory tremor. It is unclear whether connectivity-guided targeting strategies could further augment outcomes. The aim of this study was to evaluate the efficacy and safety of MRI connectivity–guided RF-T in severe tremor.

METHODS

Twenty-one consecutive patients with severe tremor (14 with essential tremor [ET], 7 with Parkinson’s disease [PD]) underwent unilateral RF-T at a single institution between 2017 and 2020. Connectivity-derived thalamic segmentation was used to guide targeting. Changes in the Fahn-Tolosa-Marin Rating Scale (FTMRS) were recorded in treated and nontreated hands as well as procedure-related side effects.

RESULTS

Twenty-three thalamotomies were performed (with 2 patients receiving a repeated intervention). The mean postoperative assessment time point was 14.1 months. Treated-hand tremor scores improved by 63.8%, whereas nontreated-hand scores deteriorated by 10.1% (p < 0.01). Total FTMRS scores were significantly better at follow-up compared with baseline (mean 34.7 vs 51.7, p = 0.016). Baseline treated-hand tremor severity (rho = 0.786, p < 0.01) and total FTMRS score (rho = 0.64, p < 0.01) best correlated with tremor improvement. The most reported side effect was mild gait ataxia (n = 11 patients).

CONCLUSIONS

RF-T guided by connectivity-derived segmentation is a safe and effective option for severe tremor in both PD and ET.
Flow diverters versus stent-assisted coiling in unruptured intracranial vertebral artery dissecting aneurysms

Published: October 2023

OBJECTIVE

Flow diverters (FDs) have been used in unruptured intracranial vertebral artery dissecting aneurysms (IVADAs) with seemingly more favorable outcomes compared with stent-assisted coiling (SAC). However, the benefits of FDs over SAC in unruptured IVADAs need further evaluation.

METHODS

This was a propensity score–matched, retrospective cohort study. Consecutive patients with unruptured IVADAs treated with FDs or SAC at the authors’ hospital between January 2016 and December 2020 were reviewed. Propensity score matching at 1:1 was based on age, significant stenosis adjacent to aneurysmal dilatation, maximum diameter, and posterior inferior cerebellar artery involvement. Periprocedural cerebrovascular complications and angiographic and clinical outcomes were compared between the two matched groups.

RESULTS

A total of 124 unruptured IVADAs in 123 patients (median age 53 [interquartile range 47–59] years; 101 men) were included. The FD and SAC groups included 65 and 59 IVADAs, respectively. Propensity score matching resulted in 47 matched pairs. The rates of immediate complete occlusion were significantly lower in the matched FD group than in the matched SAC group (6.4% vs 68.1%, p < 0.001). The rates of periprocedural cerebrovascular complications were comparable between the two matched groups (6.4% vs 6.4%, p > 0.99). At last follow-up, the rates of complete occlusion (89.4% vs 80.9%, p = 0.39) and favorable clinical outcomes (100.0% vs 97.9%, p > 0.99) were comparable, whereas the rate of recanalization was significantly lower in the matched FD group than in the matched SAC group (0.0% vs 12.8%, p = 0.03). Although the difference between the rates of in-stent stenosis was not statistically significant (17.0% vs 6.4%, p = 0.18), the difference in the effect measures was considerable.

CONCLUSIONS

In unruptured IVADAs and compared with SAC, FDs provide comparable rates of periprocedural cerebrovascular complications, favorable clinical outcomes, and follow-up complete occlusion, lower rates of immediate complete occlusion and follow-up recanalization, and likely higher rates of in-stent stenosis.

Published: October 2023

OBJECTIVE

Maximal safe resection of gliomas near motor pathways is facilitated by intraoperative mapping. Here, the authors review their results with triple-modality asleep motor mapping with motor evoked potentials and bipolar and monopolar stimulation for cortical and subcortical mapping during glioma surgery in an expanded cohort.

METHODS

This was a retrospective analysis of patients who underwent resection of a perirolandic glioma near motor pathways. Clinical and neuromonitoring data were extracted from the electronic medical records for review. All patients with new or worsened postoperative motor deficits were followed for at least 6 months. Regression analyses were performed to assess factors associated with a persistent motor deficit.

RESULTS

Between January 2018 and December 2021, 160 operations were performed in 151 patients with perirolandic glioma. Sixty-four patients (40%) had preoperative motor deficits, and the median extent of resection was 98%. Overall, patients in 38 cases (23.8%) had new or worse immediate postoperative deficits by discharge, and persistent deficits by 6 months were seen in 6 cases (3.8%), all in patients with high-grade gliomas. There were no new persistent deficits in low-grade glioma patients (0%). The risk factors for a persistent deficit included an insular tumor component (OR 8.6, p = 0.01), preoperative motor weakness (OR 8.1, p = 0.03), intraoperative motor evoked potential (MEP) changes (OR 36.5, p < 0.0001), and peri–resection cavity ischemia (OR 7.5, p = 0.04). Most persistent deficits were attributable to ischemic injury despite structural preservation of the descending motor tracts. For patients with persistent motor deficits, there were 3 cases (50%) in which a change in MEP was noted but subsequent subcortical monopolar stimulation still elicited a response in the corresponding muscle groups, suggesting axonal activation distal to a point of injury.

CONCLUSIONS

Asleep triple motor mapping results in a low rate of permanent deficits, especially for low-grade gliomas. Peri–resection cavity ischemia continues to be a significant risk factor for permanent deficit despite maintaining appropriate distance for subcortical tracts based on monopolar feedback.
Effect of thin-split encephalomyosynangiosis on transient neurological events in revascularization surgery for pediatric patients with moyamoya disease

Published: October 2023

OBJECTIVE

Transient neurological events (TNEs) are among the most important events after revascularization surgery in pediatric patients with moyamoya disease (MMD). Although hemodynamic changes and crying are representative factors of TNEs, brain compression by encephalomyosynangiosis (EMS) is another important cause of TNEs. Therefore, the authors assumed that making the EMS as thin as possible reduces the frequency of TNEs. However, thin-split EMS can lead to insufficient development of collateral vessels. This study aimed to evaluate the effects of thin-split EMS in combined revascularization surgery on postoperative outcomes in pediatric patients with MMD.

METHODS

The authors retrospectively included 56 consecutive combined revascularization surgeries in the anterior cerebral circulation in pediatric patients with MMD. These surgeries were classified into the former group and thin-split EMS group. The temporal muscle was halved in the former EMS group and split as thinly as possible in the thin-split EMS group. The authors performed between-group comparisons of postoperative stroke events and TNEs during the acute period and the development of collateral flow and stroke events during the chronic period.

RESULTS

Former and thin-split EMS procedures were performed in 37 and 19 patients, respectively. TNEs without crying or hemodynamic changes were observed significantly less frequently in the thin-split EMS group than in the former EMS group (0 [0.0%] in the thin-split EMS group vs 9 [24.3%] in the former EMS group, p = 0.021). There were no significant between-group differences in the development of indirect bypass during the chronic period (good: 34 [91.9%] and poor: 3 [8.1%] in the former EMS group vs good: 16 [84.2%] and poor: 3 [15.8%] in the thin-split EMS group; p = 0.397). Additionally, there were no significant between-group differences in the incidence of chronic clinical events, including death or stroke.

CONCLUSIONS

Thin-split EMS can reduce TNEs that do not accompany crying or hemodynamic changes. Furthermore, the procedure has sufficient prevention effects against stroke events during the chronic postoperative period in pediatric patients with MMD.
Possible Tetraquark Explanation for the Υ(10753)

     The Υ(10753) has been interpreted as a conventional bottomonium, hybrid, or tetraquark state. Given the uncertainty in the structure of the Υ(10753)) system, this paper investigates its structure in terms of a ωχbJ(1P) tetraquark. The tetraquark structure of the Υ(10753) structure is investigated using a first-order tetraquark mass formula. This mass relationship is based on weakly bound ω plus χbJ(1P) meson clusters. The first-order tetraquark mass formula provides a predicted mass within about 4% of the experimental value and the Jπ predictions are in agreement with the range of values suggested by the data.
Towards causal relationships for modelling species distribution
Authors: Da Re Daniele , Tordoni Enrico , Lenoir Jonathan , Rubin Sergio , Vanwambeke Sophie
Published: October 2023

1. Understanding the processes underlying the distribution of species through space and time is fundamental in several research fields spanning from ecology to spatial epidemiology. Correlative species distribution models (SDMs) involve popular statistical tools to infer species geographical distribution thanks to spatiotemporally explicit observations of species occurrences coupled with a set of environmental predictors. 2. So-called SDMs rely on the niche concept to infer or explain the distribution of species, though often focusing only on the abiotic component of the niche (e.g., temperature, precipitation), without clear causal links to the biology of species under investigation. This might result in an over-simplification of the complex niche hypervolume, resulting in a single model formula whose estimates and predictions lack ecological realism. 3. We believe that a causal perspective associated with a finer definition of the modelling target is necessary to develop ecologically more realistic outputs. Here, we propose to infer the geographical distribution of a species by applying the modelling relation approach, a causal conceptual framework developed by the theoretical biologist Robert Rosen, which can be formalized through structural equation modelling (SEM). 4. Implementing the modelling relation into SDMs would improve the inclusion of the causal processes underlying the spatial distribution of species into an inferential formal system, potentially highlighting the methodological steps where uncertainty arises and eventually resulting in model outputs which are tightly linked to the ecology of the target species.
Amount of carbon fixed, transit time and fate of harvested wood products define the climate change mitigation potential of boreal forest management - A model analysis
Authors: Metzler Holger , Launiainen Samuli , Vico Giulia
Published: October 2023

Boreal forests are often managed to maximize wood production, but other goals, among which climate change mitigation, are increasingly important. Examining synergies and trade-offs between forest production and its potential for carbon sequestration and climate change mitigation in forest stands requires explicitly accounting for how long forest ecosystems and wood products retain carbon from theatmosphere (i.e., the carbon transit time). We propose a novel mass-balanced process-based compartmental model that allows following the carbon path from its photosynthetical fixation until its return to the atmosphere by autotrophic orheterotrophic respiration, or by being burnt as wood product. We investigate four management scenarios: mixed-aged pine, even-aged pine, even-aged spruce, and even-aged mixed forest. The even-aged clear-cut based scenarios reduced the carbon amount in the system by one third in the first 18 yr. Considering only the amount of carbon stored in the ecosystem, these initial losses are compensated after 42-45 yr. At the end of an 80 yr rotation, the even-aged forests hold up to 31 % more carbon than the the mixed-aged forest. However, mixed-aged forest management is superior toeven-aged forest management during almost the entire rotation when factoring in the carbon retention time away from the atmosphere, i.e., in terms of climate change mitigation potential. Importantly, scenarios that maximize production or amount of carbon stored in the ecosystems are not necessarily the most beneficial for carbon retention away from the atmosphere. These results underline the importance of considering carbon transit time when evaluating forest management options for potential climate change mitigation and hence explicitly tracking carbon in the system, e.g. via models like the one developed here.
Dispersal and eco-evolutionary dynamics in antagonistic species interactions
Authors: Zilio Giacomo , Deshpande Jhelam , Duncan Alison , Fronhofer Emanuel , Kaltz Oliver
Published: October 2023

Dispersal fuels the interplay between ecology, evolution and adaptation across spatial and temporal scales. Dispersal also determines the encounter between natural enemies and can produce eco-evolutionary feedbacks with potentially profound consequences for the geographic distribution and genetic diversity of antagonistically interacting species. Although both dispersal and interaction traits, such as virulence or resistance, evolve, their concurrent evolution and impact for these dynamics remain understudied. We advocate for a more comprehensive framework, integrating dispersal, interaction and life-history trait evolution in a multi-species context. This integration may substantially alter our current vision of coevolutionary dynamics, and influence projections of range expansion, biological invasions or spreading epidemics, which is particularly relevant with ongoing global change and habitat alteration.
Molla Hüsrev’e Nispet Edilen Eserlere Dair Bir Tespit ve Tasnif Denemesi

Published: October 2023

Fatih Sultan Mehmed döneminin ve genel olarak Osmanlı tarihinin meşhur uleması arasında yer alan, ilmiye sınıfının en üst makamı İstanbul Müftülüğü mansıbına kadar ulaşıp vefatına kadar bu makamda kalan Molla Hüsrev (ö. 885/1480) daha çok fıkıh ve usûl-i fıkıh sahasında yaptığı çalışmalarıyla tanınır. Nitekim fıkha dair yazdığı Dürerü’l-hükkâm fî şerhi Gureri’l-ahkâm isimli eseri ile usûl-i fıkha dair yazdığı Mirʾâtü’l-usûl fî şerhi Mirkāti’l-vüsûl isimli eseri Osmanlı medreselerinde uzun süre ders kitabı olarak okutulmuş ve bu iki eser üzerine şerh, hâşiye, tercüme türünden birçok çalışma yapılmıştır. Molla Hüsrev’in meşhur eserleri dışında klasik kaynaklarda, yazma eser kataloglarında ve akademik çalışmalarda kendisine nispet edilen daha birçok metin, şerh, hâşiye, ihtisar, tercüme ve risale türü eserleri bulunmaktadır. Kendisine nispet edilen bu eserlerden bir kısmının ona aidiyeti kesin olmakla birlikte diğer bir kısmının aidiyeti ise tartışmaya açıktır. Literatürde sıklıkla rastlanan meşhur ulemaya çeşitli sebeplerle bilerek veya bilmeyerek yanlış eser nispet etme problemi Molla Hüsrev’in eserleri için de söz konusudur. Bu problem kaynaklarda, akademik çalışmalarda ve özellikle yazma eser kataloglarında adı geçen eserlerinin bu gözle yeniden incelenmesini gerektirmektedir. Molla Hüsrev’e nispet edilen eserlerin kendisine aidiyetini merkeze alarak yaptığımız bu çalışmada kendisine nispet edildiğini tespit edebildiğimiz kırk kadar eser bu açıdan incelemeye alınmıştır. İnceleme neticesinde müellif ile eser arasındaki nispeti doğrulamak amacıyla geliştirilmiş yöntemlerle Molla Hüsrev’e aidiyetinin kesin olduğu teyit edilen tefsir, fıkıh, usûl-i fıkıh, mantık ve belagat konularına dair yazılmış on dört eser konuları, telif sebebi, telif tarihleri ve baskı durumları dikkate alınarak kısaca tanıtılmış ve kronolojik olarak sıralandıkları bir tabloda gösterilmiştir. Kendisine nispet edilen tefsir, fıkıh, belagat ve astronomiyle alakalı on bir eserin ise nüshasının bulunamaması, eser içinde Molla Hüsrev’in adının veya diğer eserlerine atfın geçtiğinin tespit edilememesi gibi sebeplerle kendisine aidiyetinin yeniden sorgulanması gerektiği kanaati hasıl olmuştur. Tefsir, kıraat, kelam, fıkıh, vaz gibi konularda risale, şerh, hâşiye ve metin türünden Molla Hüsrev'e nispet edilen on dört eserin ise eser veya müellif isminin kütüphane kayıtlarına yanlış girilmesi, nüsha üzerinde veya akademik çalışmalarda eserin yanlışlıkla kendisine nispet edilmesi gibi çeşitli sebeplerden Molla Hüsrev’e aidiyetinin doğru olmadığı sonucuna varılmıştır. Makale Molla Hüsrev'e nispet edilen eserler hakkında yapılmış en kapsayıcı müstakil çalışma olmakla beraber özellikle yazma eser kataloglarının her geçen gün daha eksiksiz ve doğru hale gelmesiyle Molla Hüsrev’e nispet edilen eserlerin isimleri ve sayılarında değişiklik olması kuvvetle muhtemeldir.
Sabab or Ḥikma? : The Relationship between Muḥāḏāt al-Nisāʾ (Adjacency with Women) and the Ištibāh
Authors: TOPAL Ahmet
Published: October 2023

When man and woman pray adjacent to each other in a congregational prayer under certain conditions, this constitutes the phenomenon referred to in classical manuals of Islamic law as muḥāḏāt (adjacency with women). There are various scenarios under which muḥāḏāt can lead either to the invalidation of the prayer of the man or the woman or even worse all the participants. The sababs (reasons) behind the relevant legal rulings on muḥāḏāt in its various scenarios are outlined in detail in classical manuals of the Ḥanafī school, which will also be presented here briefly. This paper, however, seeks to find out the ḥikma (philosophy of law), as opposed to, the sabab, behind invalidation of prayer in congregational regular prayer in cases of muḥāḏāt. In fact, it particularly attempts to answer, for the first time in literature, the question of why the prayer of a man praying adjacent to a woman becomes invalid if they pray in congregation and yet it remains valid if they pray by themselves or in a congregational funeral prayer. What is it with congregational regular prayers that makes the difference? These questions constitute an important gap in the previous literature. To fill this gap, this paper, falling back upon classical manuals of Ḥanafī Fiqh, argues that this seems to have much to do with the legal ruling on ištibāh (doubtfulness) with regard to the position of the imām in congregational prayers, which requires participants to maintain sight of the imām directly or indirectly, which, as will be illustrated, seems to be hindered when muḥāḏāt occurs, thus causing the invalidation of prayer. Filling this gap becomes urgent and relevant especially when one considers the fact that this gap has been misused in recent scholarship to accuse Ḥanafīs of not relying on the Qurʾān and the Sunna for law-making in Islamic law and instead simply repeating the laws that existed before. It was also maintained by some contemporary scholars, again partly by using this gap in the literature, that uṣūl al-fiqh was used not to derive laws from the sources of Islamic law, the primary ones of which are the Qurʾān and the Sunna, as claimed by classical jurists, but rather to cover up this surreptitious use of existing laws and then making them appear as laws derived from the Qurʾān and the Sunna. By exploring the philosophy of law behind the legal ruling on muḥāḏāt, the present work illustrates that these accusations have no basis. Finally, revealing the relationship between ištibāh and muḥāḏāt al-nisāʾ for the first time also has the cumulative effect of substantiating idea that it is far more objective and feasible to rely on sabab (reason) or ʿilla (ratio legis), whichever applies, as opposed to ḥikma in deriving laws from the sources of Islamic law.

A Simple Two-Dimensional Convective-Diffusive Based Modelling Study of a Biosensor for Glucose Detection
Authors: Kordorwu Victus , Tegladza Isaac , Okoampah Emmanuel
Published: October 2023

Over the past decade, novel technologies for biomolecular detection of target molecules of interest have been reported. The chemical reactions that govern the kinetics of the transport of target molecules to the sensor are also of significant importance. Here we analyze how the diffusion, convection, and reaction kinetics can drive the experimental design of a simple glucose biosensor. In this work, a physically intuitive and practical understanding of analyte transport is presented by modelling and simulating a two-dimensional convective-diffusive transport phenomenon in COMSOL Multiphysics to understand the mechanism of surface capture dynamics of a biosensor under the assumption of perfect binding kinetics. The target molecule of interest is glucose. In the model, 1 mol/m3 of the glucose solution is introduced at the inlet at 1 mm/s, and the process is simulated as a stationary study. It was found that by decreasing the flow rate, a threshold exists where the detection of target molecules by the sensor is solely controlled by diffusion. Comparison of convective and diffusive fluxes of the system as well as the concentration distribution reveal that a decrease in flow rate increases diffusive transport, thus increasing the fraction of target molecules that are captured by the sensor.
Molecular Dynamics Prediction of the Solubility of Paracetamol in Polyethylene Glycol- Polylactide Copolymer Formulations
Authors: Tegladza Isaac , Kordorwu Victus
Published: October 2023

The poor dissolution profile of insoluble drugs such as Paracetamol (PCM) has been unbearable in the pharmaceutical industry. However, drug-polymer formulations are known to remedy this challenge. This study investigates the molecular dynamic prediction of the solubility/miscibility of paracetamol-polyethylene glycol-polylactide (PCM-PEG-PLA) copolymer formulation. Polymer chain analysis of various mole fractions of PEG and PLA monomers indicates that an increase in the concentration of PLA and a subsequent decrease in the concentration of PEG increases the copolymer solubility. The results also show that copolymerization of PEG increased the chain flexibility of the copolymers and the miscibility of the drug-copolymer formulation by enhancing the solubility of the copolymers. The mobility of the drug was investigated under NVE, NPT, and NVT ensembles. The simulation yields a maximum diffusion coefficient of 1.44*10-10 m2/s for the NPT ensemble.

The role of perceived risk as a moderating variable: Customer data, IndiHome Telkom Surabaya city
Authors: Laely Nur
Published: October 2023

This study aims to find out how perceived risk acts as a moderating variable, and how the quality of information systems, service quality, and perceived trust affect customer satisfaction of IndiHome Telkom users in the city of Surabaya. This study employs a structural equation model data collected from 385 respondents who were selected using a purposive sampling method. The respondents were drawn from the population of IndiHome Telkom users residing in the city of Surabaya. The sample criteria are customers who have used IndiHome for at least 3 months, and are at least 17 years old. The findings indicate that the perceived risk is with a positive moderator. Perceived trust serves as a constructive mediating factor in the association between information system quality and service quality which ultimately influence customer satisfaction.

Considerações críticas sobre o uso de solos com horizontes orgânicos em São José dos Ausentes, RS
Authors: Lunardi Neto Antônio , Valmor Nunes Salib Matheus
Published: October 2023

São José dos Ausentes, localizado a aproximadamente 1200 m de altitude, apresenta clima frio e úmido, favorecendo a gênese de solos com horizontes orgânicos. A paisagem dos Campos de Cima da Serra vem sofrendo alterações, com a implantação da agricultura. O uso agrícola desses solos, frágeis, pode levar ao seu desaparecimento com o tempo. Este trabalho objetivou identificarem-se as principais classes de solos com horizonte orgânico no município e como estão sendo utilizados. Identificaram-se em perfis abertos em barrancos as classes de solos com horizontes orgânicos. Com relação ao uso agrícola, os cultivos de brócolis e batata avançam por esses solos, que apresentam limitações ao uso, sendo a oxidação do material orgânico uma delas. Para agravamento do uso, esses solos ocorrem em relevos com declives expressivos, e as práticas de conservação do solo e água são pouco praticadas pelos produtores. Tais solos deveriam ser preservados de qualquer atividade agrícola que não seja a manutenção dos campos nativos.

Authors: MENDONÇA MARCUS , Luz Rodolfo Alves da
Published: October 2023

As áreas protegidas não são suficientes para produzir os serviços ecossistêmicos necessários à manutenção da vida. O corredor agroecológico contribui para a manutenção da conectividade e a redução da degradação de áreas protegidas e pode apoiar as áreas agrícolas na produção de alternativas econômicas. Esta pesquisa analisa a viabilidade de implantação de um corredor agroecológico entre as áreas protegidas de Carajás e da Terra do Meio, no estado do Pará, Amazônia brasileira. Para tal, foi realizado o diagnóstico econômico-ecológico dos agroecossistemas e montado um sistema de informações geográficas para delimitação do corredor agroecológico e determinação das características da paisagem. Como alternativa para uma transição agroecológica mais adaptada a esta região, se propôs o manejo da paisagem agrícola baseado na intensificação ecológica da pecuária e nos sistemas agroflorestais, com cacau sombreado, somado à restauração florestal.

Published: October 2023

Este artículo abordó la incidencia del Servicio de Rentas Internas (SRI) en las empresas constructoras del Ecuador, un sector vital que aporta un 10% a la economía del país. El objetivo del trabajo fue analizar el impacto de las determinaciones directas y presuntivas emitidas por el SRI en el sector de la construcción. Se utilizó una metodología cualitativa y se entrevistó a 6 expertos exfuncionarios del SRI, los datos recolectados se analizaron con codificación axial. Los resultados indicaron que las sanciones, se enfocan en las discrepancias entre los ingresos y los costos declarados, debido a desorganización contable y desconocimiento normativo por parte de las empresas. La normativa tributaria carece de criterios claros para la imposición de sanciones y el impacto significó dificultades financieras, cierre de empresas y multas excesivas. Finalmente, se debe llevar a cabo una revisión a la normativa para establecer sanciones adecuadas, propiciando seguridad jurídica y un ambiente favorable para el desarrollo del sector constructor en Ecuador.

Study of Physical and Mechanical Properties and Tillage Modes of Soil Under Modern Technological Principles
Authors: Tagieva Ye.
Published: October 2023

The availability of information about the physical and mechanical properties of the soil during the operation of tillage machines, including machines carrying out pre-sowing tillage, plays a key role in choosing the technological scheme and working bodies of the machine. The use of advanced tillage machines and technologies first of all requires studying the real situation of the corresponding physical and mechanical properties of the soil. From this point of view, the question raised has the same purpose. The studies were carried out on the territories of intensively agricultural regions and on samples taken from agricultural land. The results obtained during the experiment show that with an increase in the hardness of the soil from only 0.68 to 0.78 MPa, this cannot significantly affect the change in the resistivity of the working body. However, after this limit, an increase in the hardness of the soil significantly resists the working organ. In the course of the study, the physical and mechanical properties of the soil and the operating characteristics of the cutting body of the unit were also studied.

Published: October 2023

Flavonoids are an extensive class of organic compounds that are secondary metabolites of plants and higher fungi. From a chemical point of view, flavonoids are hydroxy derivatives of flavone, 2,3-dihydroflavone isoflavone and 4-phenylcoumarin. Since ancient times, various parts of plants have been considered as sources of biologically active substances for the treatment of various diseases and improving well-being. One of the most common flavonoids is apigenin — 4’,5,7-trihydroxyflavone. Apigenin is present mainly in the form of a significant amount of glycosylated substances in vegetables (parsley, celery, onion), fruits (oranges), herbs (chamomile, thyme, oregano, basil) and plant-based beverages (tea, beer and wine). This article discusses the current data of studies of anti-inflammatory, antitumor, neuroprotective and antiviral activity of apigenin. From the available data, it follows that apigenin is a promising structure showing a variety of types of biological activity, which allows it to be considered as an interesting candidate for creating new drugs based on it or for including this polyphenolic compound in complex treatment protocols as a biologically active additive.
