Authors: Olanisebe Moses , Abdullahi Sadiq , Dandago Kabiru
Published: July 2023

This paper examines the mediating effect of profitability on the relationship between managerial ownership and tax avoidance of listed companies in Nigeria. The study employed a correlational research design using data from the Nigeria Exchange Group (NGX) over the period of twelve years (2010-2021). Data was extracted from the annual report and accounts of the 121 out of 156 companies that were listed for the period. The data collected were analyzed using descriptive statistics, correlation and Structural Equation Modeling (SEM) were used as techniques for data analysis while Monte Carlo model was used to determine the level of significance of the indirect effects and the hypotheses formulated were tested. The study’s findings demonstrate that managerial ownership affects tax avoidance behavior and that the relationship between managerial ownership and tax avoidance is mediated by the level of profitability. Based on these findings, the study recommended that shareholders need to pay closer attention to corporate tax matters to verify that the business has complied with its tax duties accurately and completely. Also, to reduce the level of principal-agent conflicts and enhance tax avoidance by monitoring management activities, listed companies in Nigeria should encourage managerial shareholding because some directors do not have share in sampled companies. Furthermore, the findings could be employed to inform policy makers on effective managerial shareholding on tax avoidance among listed companies in Nigeria.

Opportunities and Challenges for Official Statistics in Digital Bangladesh
Authors: Khan Md. Musa
Published: July 2023

Governments, businesses, and the public, in general, are expected to receive information from national systems of official statistics regarding the economic, demographic, social, and environmental situation. Therefore, digitizing data collection for government statistics could have a significant social impact. Slowly but surely, government administrative data is being used more. There is scant evidence, but significant data access through satellites, point-of-sale systems, and social networks is now being researched and tested. New needs for official statistics and pressures on traditional data collection from households and companies drove these projects. New requirements for official statistics have brought about these requirements and demands. The efficient use of new data sources by the government can lay the most important evidential foundation for policies that are intended to enhance people's lives, and data that has been anonymized is also being made available to other researchers. The study aims to explore the opportunities and challenges for official statistics in digital Bangladesh and identify the potential benefits and drawbacks of using digital technologies and data sources for official statistics. By understanding these opportunities and challenges, policymakers, statisticians, and other stakeholders can develop strategies and solutions that address the challenges and leverage the opportunities to improve official statistics' quality, timeliness, and relevance. Additionally, the objective is to highlight the importance of investing in capacity building, data governance frameworks, and technology and infrastructure to promote the development of official statistics in digital Bangladesh.
The MSH2 c.793-1G>A variant disrupts normal splicing and is associated with Lynch syndrome
Authors: Li Yiming , Yu Lulu , Cui Jiajia , Yin Jiye , Wu Wei
Published: July 2023

Instruction

Lynch syndrome (LS) is the most common inherited cancer predisposition disorder of colorectal cancer (CRC) which is associated with pathogenic variants in 4 mismatch repair (MMR) genes. Here, we reported a multi-generation Chinese family clinically diagnosed with LS.

Methods

To identify the underlying pathogenic gene variants, 30 whole blood samples and 4 colorectal cancer tissue samples and their clinical data were obtained from this four-generation family. Microsatellite instability-high (MSI) testing, immunohistochemistry (IHC), and Whole-Exome Sequencing (WES) were performed to identify the MMR/MSI and the underlying gene variants. The minigene splicing assay and in vitro splicing assay were used to explore the function of this variant.

Results

MSI-H and dMMR was revealed by the MSI testing and IHC, Whole-Exome Sequencing (WES) in 3 patients successfully identified a splicing variant (c.793-1G>A) in intron 4 of MSH2. Sanger sequencing validated the WES results, and all the “healthy” individuals carrying the variant have been identified in the family by PCR. Bioinformatics analysis and in vitro minigene assay showed that the pathogenic variant affected the splicing process of MSH2 gene to generate 2 kinds defective transcription products, and consequently reduced the expression of MSH2 protein. The mutation carriers were later recommended for colonoscopy and other important cancer diagnostic inspections every 1-2 years because they both have a higher risk of LS.

Discussion

We found a pathogenic splicing variant (rs863225397, c.793-1G>A) of MSH2 gene, and furtherly confirmed that this mutation plays an important role in LS patients of this pedigree based on the vitro study. Our study indicates that one splicing mutation in the MSH2 gene (c.793-1G>A) causes LS and highlights the importance of LS gene testing.

The aim of this work is to analyze the clinicopathological characteristics and prognostic factors of patients with nuclear pedigree of esophageal cancer. The clinicopathological data and follow-up information of 3,260 patients from different nuclear pedigree of esophageal cancer who underwent radical resection of esophageal cancer were collected, and the clinicopathological characteristics and prognostic factors of the patients were analyzed. The male to female ratio of 3,260 patients with esophageal cancer was 1.7:1. The diagnosis age was ranged from 32 to 85 (60.2 ± 8.1) years old. About 53.8% of the patients were ≥ 60 years old; About 88.8% of the patients came from the high incidence area of esophageal cancer; About 82.5% of the tumors were located in the middle and lower segments of esophagus; Poor, moderate and well differentiation accounted for 26.6%, 61.9% and 11.5% respectively; The surgical margin accounted for 94.3%; 47.6% of the tumors were shorter than 4 cm in length; Clinicopathological TNM stage (0+I) accounted for 15.2%, and stage II, III and IV accounted for 54.5%, 29.9% and 0.4%, respectively. Cox analysis showed that male, diagnosed age ≥ 60 years, tumor located in neck and upper esophageal segments, poor differentiation, tumor length ≥ 4 cm, and advanced TNM were independent risk factors for the prognosis of patients in nuclear pedigree with esophageal cancer. Gender, diagnosis age, tumor location, degree of differentiation, tumor length and TNM stage are the influencing factors for the prognosis of patients with nuclear pedigree of esophageal cancer, which will provide important data for the future study of esophageal cancer family aggregation.

Authors: Paloș Ramona , Samfira Elena Mirela , Vîrgă Delia , Purić Daliborka
Published: July 2023

Introduction

An academic environment with continuously more demanding tasks requires students to capitalize on their strengths to meet the challenges and engage in learning experiences. Engaged students are deeply involved in their work, are strongly connected with their studies, and are more successful in academic tasks. The present study aimed to test a model in that core self-evaluations (CSE) predicts academic engagement (AE) directly and indirectly by increasing personal resources (i.e., psychological capital; PsyCap) in the case of two different samples, Romanian and Serbian.

Methods

Data were collected through three online questionnaires from 672 undergraduate students (Romania – 458; Serbia – 214).

Results

The findings confirmed that CSE was positively related to PsyCap, which was positively associated with AE, and PsyCap mediates the relationship between the two variables in both samples. A positive evaluation of one’s characteristics (high CSE) mainly affects the cognitive and emotional mechanism of appraising the academic-related tasks one encounters (high PsyCap), ultimately shaping their motivation and engagement.

Discussion

These results pointed out the importance of the CSE and PsyCap that support each other and increase students’ AE, explaining the mediating mechanism of PsyCap. Also, they provide insight into the students’ engagement from two different cultural and educational contexts, being helpful to universities in their effort to increase students’ engagement.
A Corrosion Maintenance Model Using Continuous State Partially Observable Markov Decision Process for Oil and Gas Pipelines
Authors: Wari Ezra , Zhu Weihang , Lim Gino
Published: July 2023

This paper proposes a continuous state partially observable Markov decision process (POMDP) model for the corrosion maintenance of oil and gas pipelines. The maintenance operations include complex and extensive activities to detect the corrosion type, determine its severity, predict the deterioration rate, and plan future inspection (monitoring) schemes and maintenance policy. A POMDP model is formulated as a decision-making support tool to effectively handle partially observed corrosion defect levels. It formulates states as the pipeline’s degradation level using a probability distribution. Inline inspection (ILI) methods estimate the latest state of the pipeline, which also defines the initial state of the optimization process. The set of actions comprises corrosion mitigation operations. The errors associated with the ILI method are used to construct the observation function for the model. The sum of inspection, maintenance operations, and failure costs for a given state and action are formulated as rewards. Numerical experiments are made based on data collected from the literature. The results showed that different policies, whether derived from solvers (theoretical) or determined from practical experience, can be compared to identify the best maintenance alternative using the model. It was also observed that the choice of the solvers is important since they affect the discounted rewards and the run time to obtain them. The model approximates the parameters and uncertainty associated with the propagation of corrosion, proficiency of inspection methods, and implementation of maintenance policies. Overall, it can be applied to improve the maintenance decision-making process for the oil and gas pipeline as it incorporates the stochastic features of the operation.
A Physicist’s View on Partial 3D Shape Matching
Authors: Koehl Patrice , Orland Henri
Published: July 2023

A new algorithm is presented to compute nonrigid, possibly partial comparisons of shapes defined by unstructured triangulations of their surfaces. The algorithm takes as input a pair of surfaces with each surface given by a distinct and unrelated triangulation. Its goal is to define a possibly partial correspondence between the vertices of the two triangulations, with a cost associated with this correspondence that can serve as a measure of the similarity of the two shapes. To find this correspondence, the vertices in each triangulation are characterized by a signature vector of features. We tested both the LD-SIFT signatures, based on the concept of spin images, and the wave kernel signatures obtained by solving the Shrödinger equation on the triangulation. A cost matrix C is constructed such that C(k,l) is the norm of the difference of the signature vectors of vertices k and l. The correspondence between the triangulations is then computed as the transport plan that solves the optimal transport or optimal partial transport problem between their sets of vertices. We use a statistical physics approach to solve these problems. The presentation of the proposed algorithm is complemented with examples that illustrate its effectiveness and manageable computing cost.

Published: July 2023

In a world in continuous evolution and in which human needs grow exponentially according to the increasing world population, the advent of new technologies plays a fundamental role in all fields of industry, especially in agriculture. Optimizing times, automating machines, and guaranteeing product quality are key objectives in the field of Agriculture 4.0, which integrates various innovative technologies to meet the needs of producers and consumers while guaranteeing respect for the environment and the planet’s resources. In this context, our research aims to propose an integrated system using data coming from an innovative experimental atmospheric and forecasting simulator (capable of predicting some characteristic climate variables subsequently validated with local sensors), combined with indices deriving from Remote Sensing and UAV images (treated with the data fusion method), that can give fundamental information related to Agriculture 4.0 with particular reference to the subsequent phases of system automation. These data, in fact, can be collected in an open-source GIS capable of displaying areas that need irrigation and fertilization and, moreover, establishing the path of an automated drone for the monitoring of the crops and the route of a self-driving tractor for the irrigation of the areas of interest.

Published: July 2023

Precipitation of nanopowders with mixed magnetite–maghemite composition was carried out under different conditions and with different separation techniques. The exact character of interactions of different iron oxide phases in the nanopowder was the main object of interest. The obtained nanopowders have spherical particles about 10–20 nm in size. Electron paramagnetic resonance (EPR) study showed that iron ions incorporate fully into magnetite and maghemite structures. The shape of the EPR line points out that single homogenous solid solutions were formed during synthesis. In the studied solid solutions, different ratios of vacancies and Fe2+/Fe3+ ratios were observed but in spite of different synthesis techniques in both cases, there were no additional diamagnetic structural phases presented.

Published: July 2023

The Pantanal biome—a tropical wetland area—has been suffering a prolonged drought that started in 2019 and peaked in 2020. This favored the occurrence of natural disasters and led to the 2020 Pantanal fire crisis. The purpose of this work was to map the burned area’s extent during this crisis in the Brazilian portion of the Pantanal biome using Sentinel-2 MSI images. The classification of the burned areas was performed using a machine learning algorithm (Random Forest) in the Google Earth Engine platform. Input variables in the algorithm were the percentiles 10, 25, 50, 75, and 90 of monthly (July to December) mosaics of the shade fraction, NDVI, and NBR images derived from Sentinel-2 MSI images. The results showed an overall accuracy of 95.9% and an estimate of 44,998 km2 burned in the Brazilian portion of the Pantanal, which resulted in severe ecosystem destruction and biodiversity loss in this biome. The burned area estimated in this work was higher than those estimated by the MCD64A1 (35,837 km2), Fire_cci (36,017 km2), GABAM (14,307 km2), and MapBiomas Fogo (23,372 km2) burned area products, which presented lower accuracies. These differences can be explained by the distinct datasets and methods used to obtain those estimates. The proposed approach based on Sentinel-2 images can potentially refine the burned area’s estimation at a regional scale and, consequently, improve the estimate of trace gases and aerosols associated with biomass burning, where global biomass burning inventories are widely known for having biases at a regional scale. Our study brings to light the necessity of developing approaches that aim to improve data and theory about the impacts of fire in regions critically sensitive to climate change, such as the Pantanal, in order to improve Earth systems models that forecast wetland–atmosphere interactions, and the role of these fires on current and future climate change over these regions.
A Pilot Study to Assess the Feasibility of Comparing Ultra-High Pressure to Low-Pressure Fire Suppression Systems for a Simulated Indirect Exterior Attack
Authors: Sanli Elizabeth A. , Brown Robert , Simmons Derek
Published: July 2023

Financial and human resource challenges constrain firefighting in rural communities. This can limit the approaches that can be used in a given residential fire situation. Effective use of portable, lower-cost equipment that would require fewer personnel and less water could greatly benefit rural communities. This study was conducted to assess the feasibility of comparing ultra-high-pressure to low-pressure fire suppression systems at low flow rates. The conditions used simulated an indirect exterior attack through a window. A purpose-built burn room and standardized class A fires were used to compare ultra-high-pressure and low-pressure systems at low flow rates. Temperatures in the burn room were recorded for each condition in triplicate. While neither operating condition resulted in full extinguishment of the fire, the ultra-high-pressure trials saw decreases in the proportion of starting temperature that were faster and of greater magnitude than for the low-pressure trials. This compares with earlier research, simulating a transitional attack that saw similar patterns for temperature cooling but resulted in extinguishment. This preliminary testing provides evidence that the burn container and room, as well as instrumentation and fuel load configurations, are appropriate for more extensive testing of such equipment for exterior fire suppression.

Authors: Rezaee Nastaran , Aunna John , Naser Jamal
Published: July 2023

In this study, a numerical investigation of the Marangoni flow in foam fractionation was conducted, with a specific focus on the film of micro-foams in both the interior and exterior regions. A three-dimensional node–film–plateau border system was employed to model the system, utilizing time-dependent mass conservation equations. The study emphasized the influence of the surfactant concentration in the foam fractionation column and the mobility of the air–liquid interface on the Marangoni velocity within the film. The results indicated that higher surfactant concentration in the reflux column resulted in a significant increase in Marangoni velocities. Furthermore, a mobile interface enhanced the Marangoni flow, whereas a rigid interface reduced its intensity. The behaviour of the Marangoni flow was explored in both interior and exterior foams, revealing distinct characteristics. The presence of a wall in the exterior foam altered the flow dynamics, leading to a reduced Marangoni velocity compared to interior films.

Published: July 2023

Currently, research on the edge effect issue in the micro-arc oxidation process primarily focuses on investigating process conditions and enhancing additives. However, some scholars have utilized finite element analysis software to simulate the edge effect during the simulation process, overlooking the investigation of the morphology of the auxiliary cathode. This study analyzes the growth characteristics of the oxide film on aluminum alloy 2A12 during micro-arc oxidation. Additionally, the inter-electrode discharge electric field is simulated using the finite element analysis method. The auxiliary cathode is optimized to mitigate the influence of the edge effect on the film layer. The findings indicate that employing a cylindrical shape as the auxiliary cathode instead of a rectangular groove leads to an increased thickness of the micro-arc oxidation film. However, it also results in an augmented length of the film layer affected by the edge effect at both ends of the workpiece. Decreasing the distance between the auxiliary cathode and the workpiece surface leads to a higher thickness of the obtained micro-arc oxidation film. Decreasing the length of the auxiliary cathode results in a reduction in both the thickness of the film layer on the workpiece surface and the area affected by the edge effect. Increasing the eccentric cone ratio of the auxiliary cathode enhances the uniformity of the micro-arc oxidation film layer. In this study, we present a novel auxiliary cathode model that incorporates a smaller cylindrical shell at the center and eccentric cone shells on each side. This model has the potential to enhance the optimization rate of the micro-arc oxidation film layer on cylindrical workpieces by 17.77%.
Corrosion Activity of Stainless Steel SS430 and Carbon Steel B450C in a Sodium Silicate Modified Limestone-Portland Cement Extract
Authors: Bonfil David , Veleva Lucien , Feliu Sebastian , Escalante-García José Iván
Published: July 2023

Stainless steel SS430 and carbon steel B450C were exposed for 30 days to the aqueous extract of sodium silicate-modified limestone-Portland cement as an alternative for the partial replacement of the Portland cement clinker. The initial pH of 12.60 was lowered and maintained at an average of 9.60, associated with air CO2 dissolution and acidification. As a result, the carbon steel lost its passive state, and the corrosion potential (OCP) reached a negative value of up to 296 mV, forming the corrosion layer of FeO, and FeOOH. In the meaning time, on the stainless steel SS430 surface, a passive layer of Cr2O3 grew in the presence of FeO, Fe2O3 and Cr(OH)3 corrosion products; thus, the OCP shifted to more positive values of +150 mV. It is suggested that a self-repassivation process took place on the SS430 surface due to the accumulation of alkaline sulfates on the interface. Because of the chloride attack, SS430 presented isolated pits, while on B450C, their area was extended. The quantitative analysis of EIS Nyquist and Bode diagrams revealed that the Rp of the corrosion process for SS430 was 2500 kΩcm2, ≈32 times lower in magnitude than on B450C, for which the passive layer tended to disappear, while that on SS430 was ≈0.82 nm.
Influence of Combined Heat Treatment and Hot Isostatic Pressure (HT-HIP) on Titanium Aluminide Processed by L-PBF
Authors: Soliman Hatem A. , Pineault James , Elbestawi Mohamed
Published: July 2023

Postprocessing is essential for improving titanium aluminide (TiAl) microstructure and part quality after using the laser powder bed fusion (L-PBF) method. It has been reported that Ti-48Al-2Cr-2Nb (%at) processed by L-PBF has internal defects and low fracture toughness. Microstructure control by heat treatment (HT) showed a significant improvement in the ductility of the material. Alternatively, hot isostatic pressing (HIPing) could be applied to reduce the residual stresses and internal defects formed during the L-PBF. Combining the benefits of these two subsequent processes into a single predetermined process is appealing for Ti-48Al-2Cr-2Nb (%at) to minimize cost. This work presents a novel strategy to postprocess L-PBF TiAl by applying combined heat treatment and hot isostatic pressing in one process, namely HT-HIP. The process includes three cycles with different conditions (i.e., temperature, time, and pressure). These conditions were determined to achieve improved part quality and microstructure. The results show that the tensile residual stresses decreased from a peak of 249 MPa in the as-built sample to compressive stresses that peaked at −90 MPa after the HT-HIP process. The number and size of internal defects could be greatly reduced. The defects were transformed into a regular spherical shape, which is good in terms of fatigue strength. Additionally, a duplex microstructure with lamellar α2/γ colonies could be introduced for better ductility. Different levels of duplex microstructure could be achieved along with the process cycles. The grain structure using EBSD analysis showed refined equiaxed grains, which demonstrate better strength after the HT-HIP process. Twinning boundaries were also observed in the HT-HIP sample. The grain orientation tendency to the build direction significantly reduced after the HT-HIP process. The nanoindentation test was applied to evaluate the nanohardness of the as-built and HT-HIP samples. It could be demonstrated that the nanohardness is dependent on the formed phases and lamellar density inside the grains. The mean hardness value was 8.19 GPa for the as-built sample, while it was 5.48 GPa for the HT-HIP sample.

Published: July 2023

The joining zone includes three main parts, which comprise an isothermal solidification zone (ISZ), the athermal solidification zone (ASZ), and a diffusion affected zone (DAZ). Field emission scanning electron microscopy (FESEM) was used here to observe the microstructure equipped with ultra-thin window energy dispersive X-ray spectrometer (EDS) system. Additionally, electrochemical impedance spectroscopy (EIS) and cyclic potentiodynamic polarization tests were conducted to evaluate the effect of the DB process on the corrosion resistance of the Inconel 625 superalloy. In the bonding time period, some Mo- and Cr-rich boride precipitations and Ni-rich γ-solid solution phases with hardened alloy elements, such as Mo and Cr, formed in DAZ and ASZ, respectively, because of the inter-diffusion of melting point depressants (MPD). Moreover, during cooling cycles, Ni-Cr-B, Ni-Mo-B, Ni-Si-B, and Ni-Si phase compounds were formed in the ASZ area at 1110–850 °C. The DAZ area developed by borides compound with cubic, needle, and grain boundary morphologies. The corrosion tests indicated that the DB process led to a reduction in the passive region and increased the sensitivity to pitting corrosion.

Published: July 2023

The paper presents an existing scenario related to the advanced integration of digital technologies in the field of house museums, based on the critical literature and applied experimentation. House museums are a particular type of heritage site, in which is highlighted the tension between the evocative capacity of the spaces and the requirements for preservation. In this dimension, the use of a seamless approach amplifies the atmospheric component of the space, superimposing, through hybrid digital technologies, an interactive, context-driven layer in an open dialogue between digital and physical. The methodology moves on the one hand from the literature review, framing the macro themes of research, and on the other from the overview of case studies, selected on the basis of the experiential value of the space. The analysis of the selected cases followed as criteria: the formal dimension of the technology; the narrative plot, as storytelling of socio-cultural atmosphere or identification within the intimate story; and the involvement of visitors as individual immersion or collective rituality. The paper aimed at outlining a developmental panorama in which the integration of hybrid technologies points to a new seamless awareness within application scenarios as continuous and work-in-progress challenges.

Authors: Khoso Ihsan A. , Katbar Nek Muhammad , Akram Urooj
Published: July 2023

In physics, mathematics, and other disciplines, new integrable equations have been found using the P-test. Novel insights and discoveries in several domains have resulted from this. Whether a solution is oscillatory, decaying, or expanding exponentially can be observed by using the AEM approach. In this work, we examined the integrability of the triple nonlinear fractional Schrödinger equation (TNFSE) via the Painlevé test (P-test) and a number of optical solitary wave solutions such as bright dromions (solitons), hyperbolic, singular, periodic, domain wall, doubly periodic, trigonometric, dark singular, plane-wave solution, combined optical solitons, rational solutions, etc., via the auxiliary equation mapping (AEM) technique. In mathematical physics and in engineering sciences, this equation plays a very important role. Moreover, the graphical representation (3D, 2D, and contour) of the obtained optical solitary-wave solutions will facilitate the understanding of the physical phenomenon of this system. The computational work and conclusions indicate that the suggested approaches are efficient and productive.

The study is carried out to establish the diversity of fish in the Napo and Arajuno rivers in the segments that cross the Ahuano parish of the Tena Canton, Napo Province in the Ecuadorian Amazon. Several studies indicate that the Napo River basin would have up to 680 species of fish (Barriga, 2012). A monitoring effort was carried out for 12 months. Trammel and trawl nets were used to collect the specimens. Sampling was carried out at five stations in each river, every 1,000 meters, once a month during the 11 months of study. As a general result, the record of 27 species of bony fish was obtained. Of the order Characiformes, 16 species were obtained, being the most diverse, while at the taxonomic family level, Characidae was more frequent with 9 corresponding species. Additionally, a survey was carried out among 5 indigenous and peasant communities on the banks of the two rivers to establish the preference for fish consumption and the potential species for management, which were: Prochilodus nigricans for 28%, followed by Pimelodus blochii 18%, Mylosoma duriventre, Leporinus pearsoni, Hypostomus oculeus, Aguarunichthys torosus, Leporinus friederici and Triportheus angulatus with 9% each.

Authors: Neto Lidefonso Zafred
Published: July 2023

A ergometria é um método amplamente utilizado na avaliação da efetividade na prevenção de doenças cardiovasculares. Esse teste envolve o monitoramento do desempenho físico do paciente durante o exercício, fornecendo informações valiosas e consistentes sobre a saúde cardiovascular. Quando esse procedimento é realizado, é possível identificar possíveis anormalidades no sistema cardiovascular, como isquemia, arritmias ou disfunção ventricular, que podem ser indicadores de risco de doenças cardiovasculares. Além disso, o teste de esforço permite avaliar a capacidade funcional do paciente e fornecer orientações sobre a atividade física adequada. Através da ergometria, é possível detectar precocemente alterações cardiovasculares, permitindo intervenções preventivas e reduzindo o risco de eventos adversos, como infarto do miocárdio ou acidente vascular cerebral.

Este trabalho tem como objetivo compreender como a privacidade de dados desponta como um direito básico inquestionável em uma sociedade globalizada e digital, demonstrando seus instrumentos jurídicos no Brasil em alinhamento a uma nova ordem mundial de respeito e inclusão digital. Para tanto, utilizou-se o método de análise qualitativo para interpretar os dados a despeito da temática em questão, contidos nos documentos oficiais do Estado brasileiro (E-Ciber e Legislações brasileiras). Por outro lado, trata-se de um estudo de caso exploratório e descritivo. A Constituição Federal garante o direito fundamental e universal dos dados na medida em que coloca em xeque a dignidade humana, por outro lado, a Lei Geral de Proteção de Dados (LGPD) e E-Ciber resulta como avanço estratégico para das produções legais impactando de forma regulado a proteção de dados pessoais e culminando como conclusão que a privacidade de dados do cidadão comum configura um novo direito básico universal e que tem sido a preocupação dos novos movimentos em prol de um mundo mais alinhando as necessidades do ser humano digital e digitalizado.

A rúcula pode ser cultivada em sistema tradicional, no canteiro, em sistema hidropônico e em sistema aquapônico. As principais doenças dessa cultura em sistema convencional e hidropônico, são as ocasionadas principalmente por fungos. Este estudo teve como objetivo comparar o desenvolvimento da rúcula em sistema convencional e aquapônico, e analisar as doenças que podem ocorrer nos diferentes sistemas de cultivo. O experimento foi conduzido nas instalações do Setor de Piscicultura do Instituto Federal Farroupilha – campus São Vicente do Sul, em sistema de recirculação de água com temperatura controlada. A semeadura foi realizada em bandejas próprias, 10 sementes por célula e o experimento durou 40 dias. Foram utilizadas as cultivares: Rokita, Donatella e Folha larga. É avaliado a altura de planta, número de folhas, peso de matéria seca (total raiz e parte aérea) quantificar e qualificar as possíveis doenças que poderiam ocorrer nos dois sistemas testados. Ao final do experimento, a cultivar Rokita apresentou maior número de folhas (6,66) não diferindo da cultivar Donatella (5,83), no entanto ambas diferiram da cultivar folha larga (4,91). A cultivar Rokita apresentou menor altura das folhas (6,75 cm), diferindo assim das cultivares Donatella e Folha larga, 8,91 e 9,58 cm. A produtividade de massa seca foi comprometida devido aos altos volumes de chuva, que se estenderam durante o estudo. Apenas observou-se baixa incidência de septoriose na aquaponia, na cultivar folha larga, não observada no sistema convencional. Concluímos que ambos sistemas apresentam condições propícias para o desenvolvimento das plantas.
