Published: November 2023

O Parasitismo é uma relação ecológica desarmônica caracterizada pela relação parasito-hospedeiro, onde o parasito espolia o hospedeiro garantindo assim os recursos necessários para sua sobrevivência. A localização geográfica e situação socioeconômica, favorecem para que o Brasil seja endêmico para a maioria das infecções parasitárias, seja causada por protozoários, helmintos ou ectoparasitos. A disciplina de parasitologia tem como foco principal o estudo dessa relação, os aspectos morfológicos, estruturais e biológicos dos parasitos e estratégias para o controle de possíveis infecções. Partindo do pressuposto “conhecer para prevenir”, as aulas práticas são de suma importância para a visualização das formas evolutivas parasitárias e suas estruturas que permitem sua classificação e favorecem o estabelecimento de infecções parasitárias. Durante o período pandêmico, e consequente implementação do ensino remoto, uma das principais dificuldades encontradas foi a abordagem de aulas práticas virtualmente. Nesse sentido, foi produzido material didático para as disciplinas de Parasitologia e Parasitologia Humana ministradas para os cursos de Licenciatura e Bacharelado em Ciências Biológicas e Enfermagem, da Unidade Acadêmica de Biotecnologia da Universidade Federal de Catalão. O referido material aborda conteúdos de aulas práticas, destacando as principais estruturas e respondendo questões específicas da conduta dentro de um laboratório de parasitologia. Para a elaboração do material foram utilizadas lâminas permanentes do Laboratório de Biologia Molecular, imagens disponíveis na internet e bibliografia sugerida das disciplinas. O material didático foi utilizado durante o ensino remoto como modelo para que os alunos produzissem portfólios como atividade avaliativa. Pretende-se, diante da qualidade do material e da boa aceitação dos alunos, utilizar esse material nas aulas práticas presenciais como direcionamento para a melhor visualização das estruturas ao microscópio de luz. Espera-se, com a disponibilização do mesmo, tornar as aulas mais dinâmicas e proporcionar a potencialização da formação de recursos humanos na área de parasitologia, além de maior engajamento e entendimento por parte dos discentes.
Panchayat System in Karnataka: Democracy, Representation and Political Parties
Authors: Krishnappa Ramya , Agarwal Pukhraj 
Published: November 2023

Abstract: As far as the Indian sub-continent is concerned local governance/panchayat has an elaborate history. The rural population have for long practiced this system of governing themselves through their representatives. The mode of working and the powers vested in the local bodies, have not been uniform throughout. The federation conferred constitutional status to the local governance bodies in 1993 and this system has progressed in an interesting way. Karnataka, a southern State in India has been ahead of time in enacting legislations dealing with local governance. Even before the amendment inserting provisions to the Constitution of India was passed, Karnataka had and was implementing extravagant laws pertaining to panchayats. Since democracy and decentralisation are closely associated with the panchayats, the idea of representation has a key role to play. The concerns with respect to involvement and influence of political parties in the local body elections are an important aspect as well.
This paper ventures out to understand the panchayat system in Karnataka, pre and post the Constitutional amendment. The paper intends to throw light on the essence of the legislations relating to panchayats in Karnataka and understand the idea of democracy, representational factor and the concept of elections on a non-party basis. The researchers have keenly pondered upon the implementation of apolitical elections in Karnataka, the flaws in the proposed phenomenon. The paper also aims to look into hurdles in the way of these local bodies and propose suggestions to get over the same.

Methodology: The research is doctrinal in nature. The authors have depended on primary sources inclusive of the Constitution of India, 1950, relevant statutes, statistical data and secondary sources including articles and research papers.

Results/Analysis: Apolitical elections to the local government bodies in Karnataka is a myth and it ceremoniously present on papers. Political parties, national and regional influence the electoral process at the grass root level. Interference of political parties in panchayat elections is detrimental to the working of panchayats.

Published: November 2023

In this work, a novel voltammetric sensor for detection of methionine was designed and prepared by using carbon paste electrode (CPE) modified with ZnO hollow quasi-spheres (ZnO hollow QSs) and 1-Butyl-3-methylimidazolium hexafluorophosphate (BMIM.PF6). The results by cyclic voltammetry (CV) showed that the prepared electrode (ZnO-BMIM.PF6/CPE) effectively increased the oxidation peak current and reduced the oxidation peak potential of methionine, and had a suitable electrocatalytic activity for oxidation of methionine. Notably, the ZnO-BMIM.PF6/CPE exhibited high detection capability towards the quantification of methionine in 0.1 M PBS (pH = 7.0) over a concentration range from 0.04 µM to 330.0 µM with a limit of detection (LOD) of 0.02 μM. More importantly, the effectiveness of the ZnO-BMIM.PF6/CPE seneor was also confirmed in real sample (urine detection with acceptable recoveries (98.0-102.7%) and RSDs values ≤ 3.3%.

Published: November 2023

Introduction: UNESCO defines Open Educational Resources (OER) as freely accessible and adaptable educational materials, whose integration in education, especially in post-pandemic times and in the digital era, has been limited, despite the efforts of institutions such as the Facultad de Estudios Superiores Zaragoza to promote their use in hybrid and flexible teaching modalities. This study analyzes the transformation of higher education in the context of the COVID-19 pandemic, focusing on the integration and impact of Open Educational Resources (OER) and Information and Communication Technologies (ICT). Methods: a literature review and analysis of current educational practices in universities was conducted, with special attention to the adoption of OER and the use of hybrid and digital teaching methodologies. Results: the results indicate that, despite the accessibility and adaptability of OER, their adoption in university education has not been extensive, mainly attributed to lack of knowledge about their use and potential. The pandemic has accelerated the need to adapt pedagogical strategies, highlighting the importance of interaction and collaboration in learning. Maker pedagogy and 3D printing are identified as valuable tools to improve understanding and practical skills, especially in the health sciences. Conclusion: the study concludes that post-pandemic education requires an adaptive, interactive and technologically integrated approach, promoting continuous learning and adaptation to changing cultural and cognitive practices. It underscores the need to democratize design and manufacturing technologies and to foster collaborative and participatory learning communities through OER

Published: November 2023

Myopia control is a significant concern for parents of myopic children, and clinical research is expanding strategies to decrease myopia progression. This article reviews peer-reviewed research on a range of strategies for slowing down the progression of myopia, such as wearing bifocal or multifocal glasses, aligning gas-permeable contact lenses, going outside, and under-correcting myopic refractive error. Numerous interventions have proven ineffective, such as myopic refractive error under-correction, gas-permeable contact lens alignment, time spent outdoors, and bifocal or multifocal glasses. The review found that myopia management measures, especially in children and teenagers, are an efficient strategy to delay myopia growth and lower the chances of excessive myopia, leading to significant eye issues later in life.

Yielded Zone Characterization While Drilling a Wellbore into Clastic Reservoirs Using Elastoplastic Modeling Approaches
Authors: Hamid Osman , Albahrani Hussain , Suaid Mohammed 
Published: November 2023

Abstract
Drilling a wellbore into a clastic reservoir exhibits complex rock behavior, including plastic deformation and yield zone development, which can affect wellbore stability and hydrocarbon production efficiency. Elastoplastic modeling methods have been increasingly used to simulate the drilling process and predict the location, shape, and size of yielded zones in the reservoir. This study aims to characterize the yielded zones in a sandstone reservoir during a borehole lifetime using elastoplastic modeling approaches. The methodology involves developing a finite element model of the sandstone reservoir using appropriate meshing techniques and boundary conditions definition for the problem. The constitutive model used in this study is the Drucker-Prager yielded criterion, which accounts for the non-linear behavior of the material during plastic deformation and yielding. The numerical method used is the finite element method, which discretizes the reservoir into small elements and solves for the stresses and strains in each element. The drilling process is simulated using incremental loading, miming the gradual application of drilling forces on the reservoir. The stress and strain fields in the reservoir were monitored during drilling, and areas of plastic deformation and yield were identified. The results showed that the elastoplastic modeling approaches used in this study accurately predicted the size, shape, and location of yielded zones in the clastic reservoir. The location and shape of the yielded zones agreed with the field observations.
Additionally, the model predicted the formation of a narrow, highly deformed zone around the wellbore, which is consistent with field observations. The size of the yielded zone depended on the drilling parameters, rock mechanical properties, and in-situ stresses. This study concludes that elastoplastic modeling approaches can be used to predict the size, shape, and location of yielded zones in sandstone reservoirs during wellbore drilling and production operations. The methodology used in this study can be used as a valuable tool for borehole planning and reservoir management. The innovation of this study lies within the use of elastoplastic modeling approaches to optimize drilling parameters and reduce the risk of wellbore instability in sandstone reservoirs. The results of this study can aid in designing drilling strategies that minimize the impact of yielded zones and improve wellbore stability, ultimately leading to increased production efficiency.

Published: November 2023

Abstract
Mining processes can lead to groundwater contamination as chemicals and metals from the rocks leach into nearby water. This study examined the chemical makeup of highly saline water, a byproduct of oil production, from two sources in the Bakken shale, North Dakota. These samples had extremely high total dissolved solids (257,000mg/L) and hardness (&gt;52,000 mg/L as CaCO3) but very low alkalinity (152.4 ± 184.9 mg/L as CaCO3). To extract the salts, agents like caustic soda (NaOH), lime Ca(OH)2, and Soda ash NaCO3 were added to the samples at 24°C. Caustic soda proved ineffective, but the softening process was successful with jar tests. Advanced analysis was done using ICP-MS. Lime and soda ash effectively removed 99.5% of hardness ions (Ca and Mg) in alkaline conditions. Specifically, lime treatment reduced Mg ions by 98.17% at pH 11.5 but increased Ca ions by 12.10%. Adjusting the pH by adding soda ash saw decreases to 10.3 at one site, removing 47.77% and 53.3% of Mg and Ca ions, respectively. Thus, lime effectively reduces Mg levels but is less effective for Ca, while soda ash is proficient in removing Ca from the water.
Predicting Formation Breakdown Pressures for Arbitrary Wellbore Orientation Using Machine Learning Techniques
Authors: Almani Tameem , Khan Khaqan 
Published: November 2023

Abstract
One of the major operational challenges facing hydraulic fracturing operations is the accurate estimation of the associated formation Breakdown Pressure. Underestimating this value can lead to frac-job cancellations, and overestimating it can result in huge expenditure loss. The complexity of the problem stems from the fact that there are several factors affecting this value, some of which are fluid-related parameters, while others are mechanical-related parameters. Conventional techniques for estimating this value rely on empirical formulas which try to approximate (or suppress) the effects of these different parameters in one or several equations. This does not necessary lead to accurate results, especially for highly heterogenous reservoirs. In this work, we will develop a machine learning approach, using Neural Networks, for computing breakdown pressure values for an arbitrary wellbore orientation. The novelty of the work presented in this paper lies in the way the training data set is prepared for the constructed Neural Network. Due to the scarcity of the training data, we will utilize the computational framework, presented in (Almani et al., 2021 (1,2)), for generating the training data-set for our Neural Network. Once the Neural Network is trained, it will be used to predict formation breakdown pressures for different wellbore orientations.
Modelling and Verification of Transient Flow and Heat Transfer for CO2 Injection Wells — Application to CCUS Project at H3 Block, China

Published: November 2023

Abstract
The growing urgency to mitigate global warming has accelerated the development of carbon capture, utilization, and storage (CCUS) technologies, including promising field CO2 injection techniques. In the H3 block of China, a large-scale CO2 injection project was implemented for CCUS-EOR. This study focuses on creating a CO2 wellbore flow and heat transfer calculation model for on-site construction guidance. The model utilized the Span-Wagner equation for CO2's unique physical properties and integrated fundamental principles like mass conservation, momentum theorem and energy conservation. Using the finite difference and iterative solving methods, a prediction model for transient temperature and pressure in the CO2 injection wellbore was developed. Verification against on-site measurements showed less than 3% error in pressure and a 5% error in temperature. It was observed that increasing the injection rates led to variations in wellbore pressure and temperature due to the increased frictional pressure drop and enhanced heat transfer between the fluid and the wellbore. Since the physical properties of the fluid and its flow and heat transfer processes within the wellbore influence each other, adopting a temperature-pressure coupled calculation model can effectively improve computational accuracy.
Advanced 4D Geomechanical Analysis in Hydrocarbon Drilling Operations
Authors: Hamid Osman , Alsudairi Nora 
Published: November 2023

Abstract
The application of 4D geomechanics is paramount in addressing challenges faced in hydrocarbon field operations, ranging from exploration to development phases. Its relevance is further accentuated during well-planning in challenging, depleted terrains. This technical discourse elucidates the integration of 4D geomechanical modeling into the strategic planning of well drilling. Leveraging 4D geomechanics facilitates a deeper understanding of subsurface dynamics, allowing for adept well-planning in intricate geological settings.
A pivotal component of 4D geomechanics involves utilizing seismic inversion volumes to delineate geological facies and structure schematics. The primary focus is the robust analysis of wellbore stability to preemptively determine the optimal mud weight window and refine drilling protocols, thereby curtailing drilling-associated risks. This aligns with the overarching objective of ensuring a conducive borehole environment that aligns seamlessly with completion and stimulation prerequisites, optimizing hydrocarbon yield.
Synergetic interactions and a harmonized approach encompassing domains like Drilling, Geology, Geo-steering, Production Engineering, and Reservoir Management underpin the success of the well. It's imperative to ascertain stress shifts across the production lifecycle to preempt and mitigate potential drilling challenges. Recognizing the heterogeneity in rock attributes, tailored 4D geomechanical models have been established. Furthermore, a dynamic reservoir simulation model addresses reservoir pressure diminution over production tenure.
Utilizing datasets from proximate wells, benchmarked 1D geomechanical models were synthesized, and subsequent 3D models were architected through interpolation. Coupling of this static representation with a dynamic simulation spanned multiple years. Detailed geological schematics steered structural deciphering. Additionally, the geomechanical model accurately predicted anomalies like reservoir compaction, subsidence, and sand ingress. Pre-drilling metrics advised optimal mud weight and drilling parameters, bolstering wellbore stability. Post-drilling assessments, supplemented by Image logs, evinced prominent stress vectors and pronounced induced fractures, with interventions using bridging materials fortifying the geological matrix.
This treatise accentuates the potency of 4D geomechanical modeling in scrutinizing wellbore stability, considering variables such as intrinsic stresses, pore pressures, rock resilience, drilling fluid dynamics, and directional drilling imperatives. The precision of geomechanical evaluations has witnessed significant enhancement via the integration of dynamic and static reservoir models. An in-depth exploration of reservoir dynamics augments this reservoir intelligence with the further amalgamation of reservoir models.
