Authors: Behforouz Behnam , Al Ghaithi Ali , Al Weshahi Saif
Published: March 2023

Understanding the research concept, its obstacles, and motivation is necessary to provide better academic services and opportunities for teachers less active in conducting research. To this end, 40 lecturers from an English Language Center with various qualifications and adequate teaching experiences in the Omani EFL context were selected as the population of this study. A questionnaire initially designed by Borg (2009) to measure/gauge? lecturers' views on research was used to collect the data. The findings revealed that the lecturers showed lower levels of research engagement due to problems such as a lack of methodological knowledge, heavy teaching loads, and unclear job specifications. In addition, objectivity was considered an essential criterion while conducting research, and published materials on the Internet were stated to be the primary source of reading about language-related resources. They also believed that conducting research would only moderately affect their teaching techniques. The findings of this study should help reduce the concerns and obstacles among lecturers and engage them more in the research area by focusing on the problems and facilitating the use of accessible resources to encourage them to conduct more research studies. Policymakers, managers, institutions, and teachers play essential roles in the new way of developing curricula, which considers teachers as researchers.

Authors: OKAN Tayfun , HABERGOTUREN ATES Seda , AKÇAM Nursel
Published: March 2023

In this study, an antenna is proposed that operates at THz spectrum for sixth generation (6G) short-range future wireless communications. A modified photonic band gap (MPBG) substrate is employed to design an octagonal ring shaped microstrip patch antenna with wideband and high gain properties. Unlike the conventional photonic band gap (PBG) form, the proposed MPBG substrate structure is created by variable sized cylindrical air holes. The radii of each air cylinder in the row is determined with the help of particle swarm optimization (PSO) algorithm, where the goal is set to achieve the highest gain and impedance bandwidth (S_11≤-10 dB) possible. The simulation results of the antennas that are built on 1) non-PBG, 2) conventional PBG and 3) the proposed MPBG substrate structures are compared. It is observed that the radiation performance is most enhanced by implementing MPBG structure. In comparison to the antenna without PBG, the reported MPBG structure offers almost 300% gain and 11% bandwidth improvement. To summarize, the designed antenna with its proposed MPBG substrate structure achieves an excellent radiation performance within a wide operating bandwidth.

Published: March 2023

Arachnoid cysts are formed by duplication of the arachnoid membrane between the arachnoid and the pia mater. Although it is very common in intracranial localization, those with spinal location are rare. Extradural arachnoid cysts of the spinal canal are extremely rare pathologies regarded as either congenital or acquired. These cysts, which can develop idiopathic, post-traumatic, and after arachnoiditis, are often detected incidentally. They present with weakness in the extremities, neuropathic pain, paresthesia, or myelopathy. Here we describe the case of a 17-year-old male patient with a history of chronic spinal trauma who attended our clinic with severe low back pain for 7 months.
Application of a conventional paravertebral block on the thorax with a novel intrathoracic approach during the intraoperative period: Two case reports
Authors: Mendes Ergun , Semerkant Tolga , Cok Oya Yalcin
Published: March 2023

Pain management significantly reduces mortality by aiding in the effective elimination of secretions after thoracic surgery. We present two cases requiring emergency surgical intervention due to major trauma. Both patients were provided pain control with an intrathoracic approach of the paravertebral block performed by a sterile-clothed anesthetist with a single-shot 20 ml injection of 0.25% bupivacaine from the inner surface to the superior costo-transverse ligament (SCTL). After extubation, the measured VAS score was no higher than 3–4, and the patients could breathe and cough comfortably. The intrathoracic approach may be an effective method to implement for postoperative acute pain.
Determination of vibration strength criterion based on elastic fracture mechanics
Authors: Горюнов Олег Владимирович , Словцов Сергей Владимирович , Горюнов Александр Владимирович
Published: March 2023

Существующие методики оценки остаточного ресурса оборудования, технологических и магистральных трубопроводов при многоцикловом нагружении (вибрации, пульсации) основаны на использовании понятия амплитуды, которая для случая широкополосного нагружения существенно зависит от параметров обработки и осреднения спектральной плотности колебательного процесса. При этом мера поврежденности, определяющая ресурс элемента системы, является необъективной величиной, зависящей от параметров обработки сигналов в большей степени, чем от характеристик самого процесса (спектра), что может негативно отразиться на оценке остаточного ресурса, а это, в свою очередь, привести к неэффективным техническим решениям и ограничениям. Результатом накопления повреждений является образование микродефекта, развитие которого под действием термомеханических нагрузок чревато разрушением материала. С целью определения более объективного критерия вибропрочности были рассмотрены стадии усталостного разрушения, что позволило на основе линейной механики разрушения предложить силовой критерий вибропрочности, учитывающий развитие малых трещин. Указанный критерий является консервативным и позволяет оценить амплитуду напряжений, которые не приводят к развитию дефекта.

The existing methodologies for estimating the residual life of equipment, process and main pipelines under multicycle loading (vibrations, pulsations) are based on the use of the concept of amplitude, which, for the case of broadband loading, significantly depends on the parameters of processing and averaging the spectral density of the oscillatory process. Wherein, the measure of damage that determines the system element’s life is a biased value that depends on the parameters of signal processing to a greater extent than on the characteristics of the process itself (spectrum), which can negatively affect the assessment of the residual life, and this, in turn, may lead to counterproductive technical solutions and limitations. The result of damage accumulation is the formation of a microdefect, the development of which under the action of thermomechanical loads is fraught with the material destruction. In order to determine a more objective criterion for vibration strength, the stages of fatigue failure were considered, which gave the opportunity, on the basis of elastic fracture mechanics, to propose a force criterion of vibration strength, which takes into account the development of small cracks. The aforesaid criterion is conservative and allows evaluating the amplitude of stresses that do not lead to the development of a defect.

Published: March 2023

Рассмотрены некоторые особенности совместного применения различных видов и методов неразрушающего контроля при диагностировании магистральных трубопроводов. Указано, что в настоящее время среди физических методов контроля в наибольшей мере используются ультразвуковая дефектоскопия и толщинометрия металла. Радиационный контроль, широко применяемый при строительстве трубопроводов, на этапе их диагностирования востребован значительно реже и в основном в качестве экспертного метода. Рассмотрены особенности выявления наиболее опасных дефектов – трещин, в том числе одиночных, формирующихся в период эксплуатации трубопроводов из локальных дефектов сварных швов, а также скоплений трещин различного происхождения. Показано, что хорошие результаты по выявлению поверхностных трещин любого вида дает применение электромагнитно-акустических преобразователей, излучающих в металл и принимающих волны Рэлея. Также отмечен положительный опыт использования вихретоковых многоэлементных (матричных) преобразователей для выявления поверхностных трещин различной природы, в том числе трещин, выходящих на поверхность валиков усиления сварных швов. Рассмотрена возможная схема совместного применения различных методов контроля при диагностировании магистральных трубопроводов, предполагающая использование статистических алгоритмов обработки результатов, полученных каждым методом по отдельности.

Some features of the joint application of various types and methods of non-destructive testing in diagnosing main pipelines are considered. It is indicated that at present the largest volumes of application of physical methods of control fall on ultrasonic flaw detection and metal thickness measurement. X-ray, which is widely used in the construction of pipelines, is used much less frequently at the stage of their diagnosis, and mainly as an expert method. The article discusses some features of identifying the most dangerous defects – cracks, including single cracks that form during operation from local defects in welds, as well as accumulations of cracks of stress-corrosion origin. It is shown that good results in the detection of surface cracks of any kind are obtained by using electromagnetic-acoustic transducers emitting into the metal and receiving Rayleigh waves. It also points to the positive experience of using eddy current multi-element (matrix) transducers to detect surface cracks of various nature, including cracks that emerge on the surface of weld reinforcement beads. A possible scheme for the joint application of various control methods in diagnosing main pipelines is considered, which involves the use of statistical algorithms for processing the results obtained by each method separately.

Application of the Gini coefficient in studies of spatial inequality in agglomerations of regions
Authors: Katonin Sergey
Published: March 2023

Strengthening the economic role of urban agglomerations is a global trend. The economic benefit from the merging of economic resources becomes possible due to agglomeration effects that trigger the accumulative process of space development. The increase in market capacity and business activity, intensive interaction in the labor market and the exchange of knowledge stimulate the development of the space. However, the negative side of agglomeration processes is the resource exposure of peripheral territories and the decrease in the standard of living of the population on the outskirts of the region. More attractive working conditions and wages in the core of the agglomeration lead to inequality in the distribution of income among the population of the region. The article examines economic inequality in the Moscow region using a popular indicator - the Gini coefficient. The author describes the reasons for the differentiation of wages among the population, provides calculations and shows the dynamics of the change in the Gini coefficient.

Authors: Zorin Grigoriy
Published: March 2023

Today, in connection with the new geopolitical realities, questions about the problems of ranking regions in countries remain essential. The relevance and novelty of the topic is argued by the need for further research on the effectiveness of ranking, through categorization, classification, clustering, stratification, using the processing of disparate information to build new principles under the existing dynamically changing realities of world economic policy. The article raises the problems of ranking and the solution through the application of the principles of dynamic ranking using short-term data from all subjects (federal districts of the country), despite the technological backwardness of the regions as a result of the absence or understaffing due to higher prices for technological means, through public and private enterprises, using information and communication technologies, by creating public-private analytics on the average. Understanding the prospects for the development of ranking, thanks to the principle of dynamic ranking, will allow you to quickly create organizational and economic measures, given the increasing sectional pressure on the Russian Federation, as part of improving economic security. This article discusses the various ranking problems and their respective features and criteria, as well as the difficulties in trying to optimize these criteria. The features of computational aspects in open research problems of ranking are considered.

Test Analysis of a 2D Seismic Survey With Finer CMP Interval
Authors: Xuewu Z.
Published: March 2023

Finer bin size or CMP interval normally means higher cost for a seismic survey, which makes sense for 3D projects because of very large equipment investment and difficulties of recording crew organization. However, the increase of active channels seems not to increase much cost for a conventional 2D seismic project in Indonesian jungle where the large portion of the cost is from line clearance, bridging, drilling and damage compensation. A test 2D line with 10 m receiver interval (RI), 60 m source interval (SI), 720 active channels and bunched geophone was acquired versus the production parameters of RI 30 m, SI 60 m, active channels 240 and arrayed geophone. The results demonstrate that flexible indoor arrays produce better effects than infield arrays where surface inconsistences exits. Data sets with RI of 20 m and 30 m with nominal full fold of 60 extracted respectively by picking one trace every two and one every three were processed. The comparisons of brute stacks with CMP interval 5 m, 10 m and 15 m demonstrate finer CMP interval can mitigate spatial aliasing and hence, improve denoising and S/N ratio. Instead of geophone array, the test data were also processed with nominal full folds of 120 and 180 by enlarging CMP intervals to be 10 m and 15 m. The comparisons indicate higher fold coverage can significantly improve seismic imaging with no negative impacts from geophone array. A trial with RI 10 m, CMP interval 15 m and SI 120 m was processed with nominal full fold 90. The purpose of such test is to seek a possible alternative of 2D geometry with dense receiver but sparse source for areas where the number of source holes is desired to be less. This paper intends to discuss ways for 2D seismic surveys cost-efficient and environmentally-friendly.
Self-Consistent Approximation for Porosity Segmentation
Authors: Joshi R.M
Published: March 2023

Carbonate reservoirs have been known to be a major source of hydrocarbons; it is well known that approximately 60% of the oil and 40% of the gas reserves in the world are found in carbonates, yet the understanding of the carbonate reservoir poses a significant challenge in exploration and exploitation. Presence of secondary porosity which differentiates it from clastic reservoirs brings its own set of complexity primarily owing to the poro-perm relationship. Carbonate fields in Bombay offshore (Western offshore of India) are no different. In order to understand the poro-perm complexity of one such field in Bombay offshore, the core samples obtained from wells went through Scanning Electron Microscopy (SEM). This study incorporates the results of experiments performed on core samples to determine the pore size distribution and the porosity of the samples at the given depth. The Self-Consistent Approximation (SCA) approach is applied on Scanning Electron Microscope (SEM) image data to determine the elastic properties of rocks and porosity partitioning of carbonate reservoir located in the western offshore region, India. The perquisites for this SCA modelling approach were sonic derived logs and SEM data extracted from core samples. The SEM images of cores from ten different depths and two different wells are analyzed by an algorithm to quantify the type of pores into cracks, inter-particle, and stiff defined by their aspect ratios. The sonic velocities were inverted using optimization technique for the entire depth range of the one well log. Machine learning algorithm was used to estimate the pore aspect ratio’s probability density. This study attempts to achieve porosity partitioning in carbonate reservoirs using SCA that will help in understanding the complex porosity system of these reservoirs and to develop a petro-physical and rock physics model to deduce the scalability of its different properties, not only in Bombay offshore but anywhere else.
Investigating Natuna Carbonate Platform Complexities Through Integration of Multi-Geophysical Datasets From Seismic FWI PSDM Reprocessing
Authors: Juliansyah M.N.
Published: March 2023

The presence of an extensive carbonate platform in the northern part of the East Natuna Basin has been widely known since seismic was first acquired in the 1970’s. From a seismic imaging standpoint, the occurrence of a massive carbonate interval in shallower depth is one of the contributing factors causing low seismic resolution in the underlying section beneath the top of the carbonate. A 3D seismic volume that was acquired in the northern part of East Natuna and processed to PSTM in 2010 proved the existence of the carbonate platform that covers the most part of the 3D area, but also showed that PSTM processing was not sufficient to deliver good enough seismic resolution of the overall seismic dataset. Seismic 3D FWI PSDM reprocessing was applied in 2021 and showed tremendous improvement in seismic resolution, as it was able to capture greater details in the shallower section, specifically the imaging of carbonate platform. This study will showcase the development and complexities of Natuna carbonate platform by using the combination of various geophysical datasets from the latest 2021 3D FWI PSDM reprocessing. It also demonstrates the practical application of seismic palinspatic restoration to investigate the growth of a carbonate platform from early to final stage and highlight the geological features in PSDM FWI reprocessed data that previously was not able to be imaged on the original PSTM processing. Three geophysical datasets including PSDM seismic stack, velocity, and variance are utilized as the main datasets. Volumes were flattened at the base of carbonate to generate a series of seismic profiles and depth slices from base to top of carbonate. Integrating these datasets is able to divide the carbonate platform into two growth stages: a lower and an upper interval with clear velocity differences. Two carbonate regions with different seismic facies characteristics and visible barrier are identified, proving the greater complexities within the carbonate platform. Intra-reef channels, faults, and reef talus are now highly visible as the result of high resolution PSDM dataset.
Seeing and Believing The Potential of Fractured Basement Reservoir in The Northern Merang High Through Seismic Identification and Modelling
Authors: Indahvinaldi A.
Published: March 2023

Fractured basement reservoir has become a future play in hydrocarbon exploration. However, several studies and concepts are still developing to date. As a part of Merang High of Jambi sub-basin, the study area is situated in a high structured basement, multi-phased tectonics, and composed of quartzite basement. By maximizing the use of recently acquired high resolution and beam migration 3D seismic data, this paper aims to evaluate the potential of fractured basement reservoir and find the sweet spots for the exploration target area. Various 3D seismic processing and analysis were generated to depict the distribution of the fractures which correlated with the actual geological condition. Subsurface mapping through seismic interpretation has also been conducted thoroughly as the structural framework becomes the main input for the modelling. Fractures were intensely found in certain areas through seismic attributes. Hence, the fracture modelling would comprehensively address that indication through demonstrating its intensity and orientation. The fractures modelling used Boundary Element Modelling (BEM) method, which utilizes fault interpretation, slip surfaces, and boundary conditions to assess strain values on each observation point. The method would predict type of mode, orientation and density of fractures. Two trends of NE-SW and E-W trending structures are well represented in the study area which complies with the two-phase tectonic history of the South Sumatera Basin. The present-day stress regime of strike-slip fault has SHmax azimuth of N67.5degE, which is generally obliqued with the average fracture orientation of N20-N30degE turned most of the fractures developed into critically stressed conditions. The areas with high critical stress value are considered to be reservoir sweet spots. Nevertheless, only drilling exploration would prove this basement potential sooner or later.
CO2 Injection and Production in Geothermal Reservoirs for Power Generation: Case Study From North Sumatra Basin of Possible Impacts of Scaling on Surface Facilities
Authors: Fitriani N.
Published: March 2023

The increasing energy demand in Indonesia comes with a large amount of anthropogenic CO2 emission which Indonesia has committed to reduce by 29% in order to meet the carbon emission target according to the BaU scenario of Indonesia's NDC (Nationally Determined Contribution) by the year 2030. Indonesia has abundant geothermal energy potential and sources of anthropogenic carbon dioxide from various industries. Based on recent trends and the latest references, supercritical carbon dioxide (scCO2) is feasible to inject into geothermal reservoirs to scavenge heat, and then produced as a working fluid to generate electricity in a process called Enhanced Geothermal System (EGS). The complex CO2–induced geochemical reactions can cause a change in reservoir porosity and affect fluid flow and heat mining rate. In this study, a comprehensive investigation on geochemical interactions between CO2–water as well as conceptual facilities of CO2 turbine was conducted. A water scaling simulation model was built to simulate the geochemical reactions in surface facilities during the CO2–EGS process. Mineral composition from several wells were modeled to calculate Saturation Index (SI) as a parameter that would indicate whether the mineral would tend to dissolve or precipitate. The geochemical simulation showed that in a North Sumatra geothermal field tested using scCO2 as a working fluid, the presence of CO2 could change water properties ( pH and alkalinity )– which could then induce the precipitation of calcium carbonate, dolomite, and silicon dioxide. The concept of using carbon captured CO2 as a working fluid for geothermal powerplant is quite new and mineral scaling due injected CO2 is an aspect that needs to be further investigated.
Onshore Kutai Basin Pore Pressure Synthesis and Hydrocarbon Accumulation
Authors: Tribuana I.Y.
Published: March 2023

Hydrocarbon accumulation in the Kutai Basin's deltaic system appears to be related to pore pressure profiles, with the largest accumulations occurring mostly between 60 - 140degC bottom hole temperature. This interval is the "Accumulation Zone," which extends from the hydrostatic pressure regime to the top of hard overpressure zone. The zone occurs due to the chemical cementation, which lithifies the rock grains and creates an inner sealing system that traps hydrocarbon effectively at the said temperature range. Below the Accumulation zone, the "Expulsion Zone” exists starting from the temperature of 140degC, which corresponds to Ro = 0.6 (Hydrocarbon Maturity), situated on hard overpressure and has very low mobility (< 1 mD/cP). A "Loss/depleted Zone" could occur well below the Expulsion Zone, with excessively hard overpressure and close to fracturing pressure. These conditions will make forming a slip fault/fracture easier, leading to drainage to reach a pressure-stress balance. Finding an ideal complete zone of such systems in the present state of the onshore part of the Kutai Basin is difficult due to existing erosional events after uplifting, except for Nilam Field. However, by reconstructing the erosional event, it is possible to comprehend the zone system and explain the relationship between pore pressure, temperature, and mobility to today's hydrocarbon accumulation, where higher erosion intensity tends to result in lower hydrocarbon accumulation.
Depositional Environment Model of Main Jurassic Sand in Ubadari Field, Eastern Indonesia
Authors: Waren R.
Published: March 2023

Reservoir presence is one of key risk in Ubadari Field. Understanding reservoir lateral extent and reservoir geometry are required to predict the range of gas in place for preparing further appraisal and/or development plan. The aim of the study is to construct robust sedimentology and depositional description of Main Jurassic Sand in Ubadari Field. An integrated approach based on core and image log data were conducted to build reliable depositional model. The study was accomplished by performing full examination from core data to define sedimentary facies and facies associations. Since the core data coverage is limited, integrating and calibrating core with image log data are important to interpret facies association for un-cored reservoir interval. Image log was heavily analyzed to get paleocurrent direction. After completing sequence stratigraphy evaluation, field scale depositional environment maps were constructed to defined reservoir lateral extent and geometry. Five main depositional environments are defined, which are floodplain, fluvial, foreshore, shoreface, and transition offshore depositional environments. Sandstone is mainly found as fluvial, foreshore, and shoreface deposits. Sandstone that was deposited as an amalgamated fluvial channel has relatively limited lateral extent with typical channel shape geometry. In the other hand, foreshore and shoreface sandstone are interpreted to be extensively distributed across the field as a sheet-sand geometry. Although the majority of reservoir is extensively distributed across both wells, several facies changes are defined from Ubadari-1 to Ubadari-2 well location, leading to potential lateral reservoir heterogeneity, especially from different depositional environment. Any available data must be incorporated to construct reliable subsurface reference case including image log. Integrated core and image log evaluation is highly valuable for building robust interpretation of sedimentology and depositional system, especially when core data coverage is limited. Understanding depositional model of Main Jurassic Sand in Ubadari Field at the early stage could allow a full-field development acceleration.
Investing in Saving Lives: Designing Second-Stage Women’s Shelters on First Nation Reserves
Authors: Allary Courtney , Thompson Shirley , Mallory-Hill Shauna
Published: March 2023

Most Indigenous women in Canada (61%) experience intimate partner violence (IPV), which is significantly worse than the high rate of 44 percent for other women in Canada. Despite the great risk for IPV, only three unfunded second-stage shelters for more than 600 First Nation reserves exist in Canada to provide First Nation women and their children a safe home. Second-stage housing offers IPV survivors transitional homes for an extended period that provide safety and renewal after their initial emergency shelter stays. This article documents the need for safe, nurturing, and culturally appropriate second-stage shelters for Indigenous women and their families to heal and rebuild. The authors provide two second-stage prototype designs based on domestic environmental analysis and concepts of houselessness, home, and co-housing. We discuss how these designs are one step in an action plan to protect Indigenous women and stop the genocide of Indigenous Peoples by supporting cultural, economic, health, and social development. The literature review and design concepts form an agenda to have design goals for housing IPV survivors that answers the “Calls to Justice for Murdered and Missing Women” and expands this needed service to every reserve.

O acesso à tecnologia tem o seu preço social, de modo que, a exemplo de grupos historicamente mais vulneráveis, ainda detém acesso a um modelo de Administração Pública digital mais limitado.
PROCESSO ADMINISTRATIVO COMO DEMOCRACIA NO ESTADO DE DIREITO.
Authors: De Carvalho Francisco Bertino
Published: March 2023

O artigo é todo construído com base em uma pesquisa e em uma análise interdisciplinar, reunindo aspectos históricos e jurídicos, e realizado, predominantemente, pelo método dedutivo a partir de fontes legislativas e doutrinárias. De início, busca a origem do processo na história ocidental na Grécia e em Roma para revelar seu papel, desde o surgimento, como instrumento de racionalização do exercício do poder no âmbito do Estado nas sociedades ocidentais antigas de pretensões democráticas, em especial em oposição ao modo de exercício do poder nas sociedades do oriente próximo e distante, estruturadas estas em concepções onipotentes e despóticas de governantes e de governos. Desta raiz histórica, apresenta-se o processo (administrativo, legislativo e judicial) em sua relação com o Estado de Direito e com o governo constitucional como uma construção das sociedades inspiradas na tradição greco-romana. Então, com o foco concentrado na apresentação do elenco dos princípios constitucionais e legais do processo administrativo, reunidos em função da hierarquia das respectivas matrizes normativas, faz-se a correlação destes com a efetivação do Estado Democrático de Direito. Ao final, é estabelecida uma relação entre o processo administrativo, dever do Estado e direito do cidadão, com a legitimidade jurídica e democrática do poder, para o caracterizar como um dos pilares de uma sociedade democrática contemporânea.

O objetivo do presente trabalho é analisar o instituto da arrecadação de imóveis abandonados, a sua aplicabilidade e as dificuldades na sua implementação. A intenção do abandono da propriedade deve ser considerada pelos requisitos presentes no artigo 1.276 do Código Civil. Além disso, o procedimento de arrecadação dos imóveis abandonados deve observar os requisitos gerais estabelecidos pela Lei nº 13.465/2017. O Município de Porto Alegre, como forma de efetivar o princípio da segurança jurídica, regulamentar e efetivar a implementação do instituto da arrecadação de bens abandonados, editou o Decreto nº 19.622, de 28 de dezembro de 2016. Com base nesse Decreto, foi instituída a Comissão de Análise e Gerenciamento de Imóveis Abandonados (CAGIM), que tem por finalidade identificar os imóveis abandonados passíveis de arrecadação pelo Município e conduzir o processo administrativo. O método utilizado nesse trabalho foi a análise da legislação aplicável à arrecadação de imóveis abandonados, revisão de doutrina e análise dos processos eletrônicos administrativos que tramitaram pela CAGIM/Porto Alegre, a fim de identificar as dificuldades apresentadas na implementação do instituto e possíveis sugestões de aperfeiçoamento.

Introduction: Breast cancer is the object of thousands of studies worldwide. Nevertheless, few tools are available to corroborate prediction of response to neoadjuvant chemotherapy. Artificial intelligence is being researched for its potential utility in several fields of knowledge, including oncology. The development of a standardized Artificial intelligence-based predictive model for patients with breast cancer may help make clinical management more personalized and effective. We aimed to apply Artificial intelligence models to predict the response to neoadjuvant chemotherapy based solely on clinical and pathological data. Methods: Medical records of 130 patients treated with neoadjuvant chemotherapy were reviewed and divided into two groups: 90 samples to train the network and 40 samples to perform prospective testing and validate the results obtained by the Artificial intelligence method. Results: Using clinicopathologic data alone, the artificial neural network was able to correctly predict pathologic complete response in 83.3% of the cases. It also correctly predicted 95.6% of locoregional recurrence, as well as correctly determined whether patients were alive or dead at a given time point in 90% of the time. To date, no published research has used clinicopathologic data to predict the response to neoadjuvant chemotherapy in patients with breast cancer, thus highlighting the importance of the present study. Conclusions: Artificial neural network may become an interesting tool for predicting response to neoadjuvant chemotherapy, locoregional recurrence, systemic disease progression, and survival in patients with breast cancer.

Penelitian ini bertujuan untuk mengetahui besarnya ragam aditif dan ragam dominan pada sifat-sifat kuantitatif populasi F2 tanaman jagung (Zea mays L.) hasil persilangan P8IS dengan NK212 dan NK7328. Dalam penelitian ini, digunakan metode eksperimental dengan percobaan di lapangan pada bulan April hingga bulan Oktober 2022 di Dusun Amor-Amor Desa Gumantar Kecamatan Kayangan Kabupaten Lombok Utara. Penelitian dilakukan dua musim tanam, pada musim tanam pertama membuat hubungan kekerabatan dengan rancangan persilangan North Carolina I (NC1) dan musim kedua pengujian hasil persilangan. Rancangan yang digunakan pada percobaan ini yaitu Rancangan Acak Kelompok (RAK) dengan 120 perlakuan yang berasal dari 40 tetua jantan. Setiap perlakuan diulang sebanyak 2 kali, sehingga terdapat 240 unit perlakuan. Data yang diperoleh dianalisis menggunakan analisis varian (ANOVA) dengan model NCI. Selanjutnya dihitung ragam aditif dan ragam dominan sesuai hasil analisis ragam. Parameter yang diamati meliputi umur keluar malai, umur keluar rambut tongkol, jumlah daun per tanaman, sudut daun, tinggi tanaman, diameter batang, tinggi tanaman, umur panen, bobot tongkol lering panen, diameter tongkol, panjang tongkol, bobot berangkasan segar, jumlah daun hijau, bobot biji kering pipil per tanaman, dan bobot 1000 butir Berdasarkan hasil penelitian diperoleh sebagian besar sifat yang diamati memiliki ragam aditif yang bernilai negatif dan seluruh sifat kuantitatif yang diamati memiliki nilai ragam dominan lebih tinggi dibandingkan ragam aditif sehingga disarankan untuk perbaikannya dengan pembentukan hibrida..
Camilo Castelo Branco e Diogo do Couto
Authors: Vanzelli José Carvalho
Published: March 2023

O cronista quinhentista Diogo do Couto (1542-1616) é recordado na história lusitana como um denunciador da corrupção e dos problemas político-administrativos na Índia portuguesa. Camilo Castelo Branco (1825-1890) também é conhecido por seu tom crítico e desconstrutivo de mitos históricos, tanto em seus romances, quanto em seus textos historiográficos. Assim, encontramos na crítica camiliana sugestões de aproximação de seus posicionamentos às denúncias de Couto, mais de dois séculos anterior. Este trabalho tem por objetivo refletir sobre o quanto dos posicionamentos camilianos expressos em seus textos são coincidentes com as críticas encontradas em Couto. Para tanto, nosso foco analítico estará mormente nas obras O Soldado Prático, de Couto, e O Senhor do Paço de Ninães, de Camilo.
Casar-me por amor ou porque meu pai mandou? Uma análise da representação do casamento em Estrelas Propícias (1863)
Authors: Sales Bruna de Oliveira
Published: March 2023

Por muito tempo, o casamento foi associado à obtenção de vantagens para as famílias dos cônjuges, sendo as mulheres moedas de troca, assumindo uma posição submissa aos maridos. Após importantes marcos históricos como a Revolução Francesa, em 1789, alguns matrimônios passaram a ser celebrados não mais por conveniência, mas sim por amor, o que causou muitos conflitos familiares. Dessa forma, a partir do romance Estrelas Propícias (1863), do escritor português Camilo Castelo Branco, pretende-se analisar a representação do casamento, buscando entender como se davam as relações sociais em prol da obtenção de um casamento vantajoso para as famílias envolvidas, sem deixar de perceber a escrita camiliana, que tanto impacta a experiência de leitura.
