Räumliche Differenzierung und lokale Entwicklung : divergente Transformationspfade am Beispiel serbischer Kommunen
Authors: Winkler Andreas
Published: April 2024

Die Länder Südosteuropas sind von enormen regionalen Ungleichheiten geprägt. Diese sozioökonomischen Polarisierungen können sowohl auf globale Zusammenhänge und eine sich weiter ausdifferenzierende Wirtschaft als auch auf langanhaltende Folgen der jeweiligen postsozialistischen Transformationen zurückgeführt werden. Besonders zu bewerten sind jene Prozesse in Serbien. Hier bestanden zum einen durch den jugoslawischen „Marktsozialismus“ gute Ausgangsvoraussetzungen für Reformen; zum anderen wurde das Land durch die ein Jahrzehnt andauernde Isolation und Desintegration wirtschaftlich und gesellschaftlich weit zurückgeworfen. Die Diskrepanz zwischen einer unterbrochenen bzw. verzögerten Transformation einerseits und den Erfordernissen globaler Integration andererseits spiegelt sich in den räumlichen Disparitäten des krisengebeutelten Landes wider. Detaillierte Analysen zu einzelnen Gemeinden offenbaren dabei einen belastbaren Blick auf die gesamte Bandbreite divergenter Entwicklungspfade innerhalb dieses Kontextes. Insbesondere auf der lokalen Ebene lassen sich die strukturellen und institutionellen Ursachen der räumlichen Ausdifferenzierung und damit des Niedergangs der einen oder des Aufschwungs der anderen Kommune unmittelbar identifizieren. Weit zurückreichende Pfadabhängigkeiten sowie eine Folge von Reorganisationen und Rekombinationen können lokale Investitionsmöglichkeiten schaffen oder verhindern, während verfestigte industrielle Strukturen oft zu lokalen Krisen führen, jedoch auch alternative Formen des lokalen Wirtschaftens hervorbringen können. The countries of South-eastern Europe are characterized by enormous regional inequalities. These socio-economic polarisations can be traced back to general global changes and an ever more differentiating economy as well as to long-lasting consequences of the post-socialist transitions of the respective states. In Serbia, these processes need to undergo a particular examination. On the one hand, the Yugoslavian system of “market socialism” provided good preconditions for reforms. On the other hand, the country was cast back economically as well as socially by a decade of isolation and disintegration. The discrepancy between a transition, that has been interrupted or delayed, and the requirements of global integration is reflected in the spatial disparities of a country ridden by crises. Detailed analyses of single municipalities reveal a precise view on the range of divergent development paths within this context. On the local scale in particular, the structural and institutional causes of the country’s spatial differentiation, i.e. the decline of one municipality and the prosperity of another, can be directly identified. Path dependencies deeply rooted in history as well as a sequence of reorganisations and recombinations can create or hinder local investment opportunities, whereas industrial lock-ins often lead to local crises, but can also generate alternative forms of local economic activity.

O canto coral dentro da universidade e a produção de conhecimento interdisciplinar
Authors: Matter Suelen , Sant'Anna Denise
Published: April 2024

A finalidade da universidade é produzir conhecimento, propor e preparar para o novo, seja qual for a área de conhecimento. Como fazê-lo a partir de um projeto de canto coral de nível extensionista? É possível aliar o fazer artístico com a produção de pesquisa dentro de um projeto de extensão? Indo além, como articular essa prática musical com diversas áreas de conhecimento de nível superior? Como promover a transdisciplinaridade? Responder a essas perguntas e promover interlocuções entre ensino, pesquisa e extensão foi um dos desafios da última década dentro do Projeto Movimento Coral Feevale, um projeto de extensão que é desenvolvido em uma universidade comunitária. O objetivo geral desta pesquisa é identificar como o projeto faz para tornar-se espaço de produção, e não apenas de reprodução de conhecimento. Os objetivos específicos foram realizar um levantamento bibliográfico sobre o canto, descrever o projeto e as suas articulações com diversas áreas do conhecimento, identificar a promoção de práticas de pesquisa, e refletir sobre o trabalho da equipe do projeto em sua atuação profissional com o canto, identificando a ocorrência ou não da transdisciplinaridade. O método utilizado foi a revisão bibliográfica com abordagem qualitativa, fazendo um levantamento de pesquisas realizadas acerca do canto, articulando com o relato de experiência do projeto extensionista de canto coral. A discussão mostra que é possível articular o fazer extensionista de canto coral com a pesquisa e o ensino.

Aims: The optimal timing for DAA therapy initiation in patients with chronic hepatitis C (CHC) and HCC is still debated. The aim of our study was to provide real-world data on virological response and overall survival in patients with hepatitis C-related HCC.

Methods: Retrospectively, we included patients with HCV-related HCC between 2015 and 2020. The primary outcome was to compare the SVR rate in the patients with active or historical HCC who were treated with DAA therapy. The secondary outcome was to measure the overall survival of those patients.

Results: 98 patients were included, and the majority were cirrhotic with compensated liver disease. 71.4% received DAA therapy at the time of initial HCC diagnosis and 11.2% received HCV treatment at the time of HCC recurrence (Active HCC cohort). 17.3% had previously received HCC treatment, but there was no evidence of recurrence at the time of DAA (Historical HCC Cohort). The SVR rate was 81.6%, but decreased to 75.7% in patients with active HCC. The presence of active HCC and the number of HCC nodules were the only factors associated with not achieving SVR in the multivariate analysis. The median survival was higher in those who achieved SVR. Active HCC and failure to achieve SVR were the main factors associated with mortality.

Conclusions: Treating hepatitis C in patients with HCC is feasible with significant rates of SVR, even if SVR rates decrease in patients with active HCC and these patients require more than one DAA therapy. Failure to achieve SVR is one of the main factors associated with mortality.

Published: April 2024

In the pursuit of discerning patterns within computer network attacks, the utilization of Machine Learning and Deep Learning algorithms has been prevalent for crafting detection models based on extensive network traffic datasets. Furthermore, enhancing detection efficacy is feasible by applying cluster learning techniques, wherein multiple Machine Learning models collaborate to yield detection outcomes. Nevertheless, it is imperative to discern the optimal features within the dataset for training the intrusion detection model. In the present study, we proffer a novel framework for feature selection and intrusion detection within industrial networks, employing Ensemble Learning to achieve commendable performance in terms of both high predictive accuracy and efficient learning duration. The outcomes evince that the proposed model exhibits an accuracy of 99.93%, with a mere one h and 34 min required for comprehensive training. In contrast, a model trained without the framework presented in this paper attains an accuracy of 99.94%, necessitating an extensive training period of 156 h. Notably, the detection model derived from the proposed solution demonstrates superior results in prediction time, accomplishing predictions within 0.0009 seconds, compared to the alternative model which requires 0.0076 seconds for predictions.

Background: The presence of cavities causes bacterial invasion and spread of infection to the pulp tissue. If left untreated, infection will lead to pulpal necrosis. Root canal treatment can prevent caries from developing into necrosis. The success of treatment is influenced by the preparation and irrigation stages. One of the bacteria that survived after the treatment was Streptococcus mitis. The irrigation solution used in treatment is a 2% chlorhexidine gluconate. Ethanol extract from Ramania leaves is known to contain flavonoids, phenols, alkaloids, steroids and terpenoids which proven to have antibacterial activity. Objective: To analyze the antibacterial effectiveness of Ramania leaf extract  concentrations of 10%, 15%, 20%, 25% and 30% against the growth of Streptococcus mitis . Methods: The research conducted was a true experimental study with 6 treatment groups and 4 repetitions. This study used broth and agar dilution methods to determine the minimum inhibitory concentration (MIC) and the minimum bactericidal concentration (MBC) of ramania leaf extract against Streptococcus mitis. Results: The MIC was shown by 10% concentration with a decrease in absorbance value of 1.726. The MBC in this study were not found because there was still bacterial growth in the concentrations of 10%, 15%, 20%, 25% and 30%. Conclusion: Ramania leaf extract concentrations of 10%, 15%, 20%, 25% and 30% can inhibit the growth of Streptococcus mitis with MIC value at a concentration of 10%. The MBC value was not found because the extract had not been able to kill the growth of Streptococcus mitis. Keywords : MBC,  MIC, Ramania Leaf Extract, Streptococcus mitis

Risks and Benefits in Using RPA in Financial Reporting
Authors:   Alexandru Ioan Cuza University of Iasi, Romania, TOFAN Dragos Ovidiu , AIRINEI Dinu ,   Alexandru Ioan Cuza University of Iasi, Romania
Published: April 2024

In the general picture of financial-accounting processes digitization, RPA (Robotic Process Automation) tools are distinguished by a series of characteristics given, mainly, by the ability to replicate human activities. Thus, unlike Artificial Intelligence, Machine Learning or Cognitive Computing, RPA acts primarily in the user interface area based on clearly defined protocols and procedures without compromising or modifying the basis of the IT infrastructure. That's why these solutions are considered non-intrusive, easy to use and cheaper compared to other financial reporting automation technologies. However, beyond more or less quantifiable benefits, these programs carry certain risks whose awareness is essential to achieve the desired goal of automation. This paper, in addition to presenting the opportunities created by aligning RPA to facilitate financial monitoring and reporting efforts, pinpoints a series of challenges or weaknesses of these solutions that, if not properly managed or combated by alternative solutions, can at least lead to the failure of such a project. The practice of the last years together with the diversification of automation solutions already allow the generation of some conclusions as well as the adoption of a cautious approach regarding the attractiveness of RPA in designing and building financial reports.

Authors: Casagrande Isabelli Bottene , Casarotti Gabriel Antonio Gianjope , Lima Claudio
Published: April 2024

Chemotaxonomy is a systematic approach to plant classification based on discernible variations and similarities in their biochemical compositions, with a particular emphasis on secondary metabolites that often exhibit specificity within taxonomically related plant species. In the context of our investigation, we conducted a comprehensive chemotaxonomic analysis of sweet oranges utilized in concentrated juice production. This involved a thorough examination of antioxidant activities, characterization of flavonoid and phenolic profiles, UV-visible spectra scanning, and the implementation of color analysis. The results from cluster analysis demonstrated the superior efficacy of color analysis in discerning subtle distinctions among orange varieties. Further refinement in the analytical process requires the application of supplementary techniques after an exhaustive and precise extraction facilitated by organic solvents. Notably, all employed methodologies successfully discriminated between distinct orange types. While the compilation of extensive datasets presents inherent challenges, the incorporation of Principal Component Analysis (PCA) and Hierarchical Cluster Analysis (HCA) enhances the interpretability of the obtained results. Considering that existing methodologies for assessing fresh fruit quality rely on subjective human visual inspection or orange juice analysis by ratio, which may lack precision in quantifying chemical constituents, there exists a growing demand for expedited techniques that can reliably ensure the quality of orange juice within the industry.

Objective: This study aims to evaluate the quantitative characteristics and growth hormone gene diversity of thin-tailed sheep in Sitinjau Laut, Kerinci Regency.

Methods: The research method used 60 thin-tailed sheep and 60 samples of thin-tailed sheep's blood. The phenotypes observed included: body weight, weight gain, body measurements, and thin-tailed sheep blood samples. The GH gene was identified using the PCR-RFLP method with the Msp1 restriction enzyme. Data analysis included t-test, t2-hotelling, principal component analysis, and allele genotype frequencies.

Results: The results showed that body weight, body weight gain, and sizes of male thin-tailed sheep were significantly different (P<0.05) higher than females. The analysis results on the GH|Msp1 gene locus of thin-tailed sheep were monomorphic with one type of allele, namely ++.

Conclusions: The average body weight, weight gain, and body measurements of male thin-tail sheep were higher than that of females. The body size characteristic of male and female thin-tailed sheep is the chest circumference, while the body shape characteristic of male and female thin-tailed sheep is the chest depth. The fragmentation of the GH|Msp1 gene in thin-tailed sheep is monomorphic.
Recovery-Impacting Petrophysical Alterations of CO2-EOR Application in Carbonate Formations: Case Study on North Dakota's Upper Red River
Authors: Abes Abdelmalek , Michael Andreas
Published: April 2024

Carbonate-based mineral dissolution and precipitation, driven by carbon dioxide (CO2) injection, introduces complexities into carbonate reservoir systems, triggering interactions that are different than those seen in traditional CO2 enhanced oil recovery (CO2-EOR) applications in siliciclastic/sandstone reservoirs. The thrust of this paper is to couple experimental (laboratory-scale) and numerical (computationally-assisted) analyses in order to assess how CO2-induced petrophysical alterations impact the resultant hydrocarbon recovery from CO2-EOR application in carbonate reservoirs.

The Upper Red River Formation, located in North Dakota's Cedar Creek Anticline (CCA) Field presents significant remaining oil-in-place, albeit a high-water saturation from waterflood operations undergoing since the 1960s. The residual (post-waterflooding), oil saturation, makes the Red River Formation a good target for modern-day CO2-EOR technology. The first part of this study involves a core-scale investigation of dynamic-permeability variations triggered by CO2 injection into three primary-productive zones, designated as "Red River Units" (RRU2, RRU4, and RRU6). The second part involves a compositional reservoir model built in SLB's Petrel software to perform numerical simulations of CO2 injection incorporating pre-established permeability variations that honor our laboratory-obtained results.

Correlations between differential-pressure variations observed during carbonated-brine (CO2/brine) injection were assessed against pore volumes injected (PVI). These pressure fluctuations were induced by dynamic-permeability variations resulting from carbonate-based mineral dissolutions/precipitations. Baseline-permeability variations were established a-priori using nitrogenated-brine (N2/brine) injection in order to correct for physico-chemical effects from the brine. During CO2/brine injection, the recorded permeability increased significantly compared to its original value, peaking before gradually recovering.

The history-matched compositional reservoir model was used to project the production from CO2-EOR through a section incorporating four existing wells, integrating laboratory-derived dynamic-permeability variations into the model, yielding different results due to incorporating laboratory-derived dynamic-permeability variations compared to simulations performed at constant permeability. Reduced reservoir permeability correlated with decreased oil recovery, emphasizing the significant impact of dynamic-permeability variations on CO2-EOR performance.
Carbonate Wettability Alteration: Core Flooding Test Under Reservoir Conditions with Carbonate Rock and Oil Samples from the Brazilian Pre-Salt

HIGHLIGHTS

Evaluation of carbonates wettability modifier under Pre-Salt reservoir conditions.

Rock and oil originating from the Brazilian Pre-Salt.

Core flooding test under pre-salt reservoir conditions

Carbonates wettability modifier.

Surface agents can be used in different forms in upstream oil and gas production. One application is to enhance oil recovery by reducing interfacial tension (IFT) or changing the wettability of rocks from oil-wet (OW) to water-wet (WW). They can also be used for flow assurance purposes, preventing the deposition of inorganic scales. However, reducing IFT through surfactant application may lead to the formation of stable emulsions, complicating the separation of water from oil during primary processing. This study aims to evaluate the efficiency of a hydrotrope, specifically the phosphoric ester of glycerol (PEG-H), in increasing the hydrophilicity of carbonate petroleum reservoirs without significantly reducing IFT. The evaluation was conducted through a core flooding test to simulate pre-salt reservoir conditions, with a reservoir pressure of 6200 psi and a temperature of 84°C. The rocks and crude oil used in the test originated from the Brazilian pre-salt. The results demonstrate that the hydrotrope successfully enhances the hydrophilicity of carbonate rocks, resulting in an increased oil recovery factor, while maintaining a high IFT level.
