O diagnóstico tardio é um fator que determina mau prognóstico para os pacientes com câncer, especialmente para tumores cerebrais agressivos, como o glioblastoma (GBM), em que a taxa de sobrevida média, em 1 ano, chega a 30% dos casos. Neste contexto, a busca por biomarcadores para detecção precoce da doença e avaliação prognóstica é de fundamental importância para melhorar os resultados clínicos dos pacientes com GBM. O presente estudo trata-se de uma revisão bibliográfica do tipo narrativa. Foram analisados 33 artigos, selecionados entre os anos de 2007 a 2022, considerando a proteína BAP1 e sua relação com o estabelecimento do GBM. O gene BAP1, localizado no locus 3p21.1, codifica o domínio catalítico primário da proteína BAP1, que tem como função remover sinais de ubiquitina de substratos proteicos. BAP1 atua em diversas vias de sinalização celular, tais como: morte celular, controle do ciclo e proliferação celular, resposta de danos ao DNA e modificação da cromatina e quando alterado favorece o estabelecimento de uma neoplasia. Embora, a proteína BAP1 tenha sido considerada como um biomarcador tumoral candidato a avaliar prognóstico em diferentes tipos de tumores, mais investigações são necessárias para elucidar melhor as interações desse alvo e seu potencial papel como biomarcador em tumores do sistema nervoso central, incluindo GBM.

Plagiarism is an offense and an ornament to science. Plagiarists steal the work of other authors or what is commonly called cheating or plagiarizing without citing the origins of the original author. Plagiarism is an act that is vulnerable to criminal activity and this problem must be considered in as much detail as possible. The act of plagiarism is recognized as an act that is disapproved and contrary to the scientific spirit in the academic world in universities. Several types of plagiarism can be distinguished by intentional or unintentional plagiarism motivation, ways of committing plagiarism include handwriting, inappropriate paraphrasing, and summaries, plagiarism itself can be said to be recycling text, redundant or duplicate publications, data fragmentation . The purpose of this study is to find out the legal arrangements for plagiarism of scientific work in tertiary institutions and to find out the legal consequences for perpetrators of the crime of plagiarism of scientific work in tertiary institutions. The research method used by the author is normative research method which positions the law as a building system of norms. There is no law that specifically regulates plagiarism, but someone who commits plagiarism or is called a plagiarist is regulated in Article 1, Minister of National Education Regulation number 17 of 2010 concerning the prevention and control of plagiarism in tertiary institutions. There are several reasons for someone to commit plagiarism, such as the convenience obtaining information via the internet, pressure on academic assignments, poor writing skills, rushing to write under pressure, lack of knowledge and understanding of how to rewrite original references, misunderstandings to self-understand plagiarism, and habitual cheating or plagiarism, such as avoiding theft intellectual, do good writing i.e. quote and paraphrase, and try the same thing or detect plagiarism in many ways like using plagiarism apps or turnitin.

Academic ethics refers to the rules or norms that govern ethical behavior in the academic world. Academic ethics includes values ​​held by the academic community, such as integrity, honesty, hard work, creativity, academic freedom, and social responsibility. Academic integrity is very important in academic ethics, because it involves honest and honorable intellectual skills and research skills. Intellectual skills include the ability to generate, collect, and analyze data, while research skills include the ability to plan, carry out, and publish high-quality research. Honesty and rigor are core values ​​of academic ethics, as they form the basis of research and teaching processes. Honesty means that academics must avoid fraud, plagiarism, and misuse of data, whereas thoroughness means that they must examine data carefully and ensure that the information they use is true and accurate. Creativity is also an important value in academic ethics, because academics are expected to produce original and innovative research and work. However, creativity must be carried out within an ethical framework and must not violate the values ​​of integrity and honesty. Academic freedom is also an important value in academic ethics, because it guarantees that academics can work independently and produce research and works that are not influenced by political or economic interests. However, academic freedom must be balanced with social responsibility, namely that academics must be responsible for the consequences of their research and teaching on society and the world. Overall, academic ethics is very important in the academic world, because it involves norms governing ethical behavior and maintaining integrity and honesty in the process of research and teaching.

Applicability and performance analysis of the phase-field modelling based on the Cahn-Hilliard method for the binary alloys
Authors: Dudek Kamil , Szeliga Danuta 
Published: August 2023

The Cahn-Hilliard method descries the driving force of the process of phase separation. Considering a binary (two-phase) alloy of conserved composition variable, the C-H model makes it possible to trace the process at which the domain creates pure subdomains of each component. Gururajan et al. have offered a simplified reference implementation of the aforementioned model, using the C language and FFTW libraries. It allows to perform a reverse Fourier transform to acquire a domain composition profile at a given time. Being a proof-of-concept, this approach does not stress on performance and the dedicated tools, like OpenPhase might not provide the flexibility necessary for new implementations. The following work aims on analyzing the C-H algorithm with regards of optimization, taking the Gururajan, among others, as a reference problem. Utilizing the models accompanied by replicable results facilitates the analysis of FFTW and GSL libraries, answering whether to search the replacement implementations and where (if necessary) work on code performance and parallelization. Finally, the improved model is intended to be used on external (non-random) initial composition, taken from ongoing simulations, in hope of preparation of the pearlitic steel model in the future.
Digital Image Correlation (DIC) system as a verification tool for constitutive models of deformation with complex strain path changes
Authors: Graca Paulina , Muszka Krzysztof , Majta Janusz , Perzyński Konrad 
Published: August 2023

Effects of the strain path changes that occur during metal forming have been the subject of theoretical and experimental studies in the light of deformation inhomogeneities. Modern multiphase steels were used as their mechanical properties are very sensitive and strictly dependent on the combination of microstructure components with different levels of their mechanical responses. DIC as a precision tool has been used to investigate the deformation inhomogeneity during the tensile tests of specimens previously deformed with complex strain path history. The study was focused on the combined metal forming processes (i.e. Accumulated Angular Drawing (AAD), Wire Drawing (WD) and Wire Flattening (WF)). These processes are characterised by a combination of various deformation mechanisms (area reduction, torsion, bending, burnishing), and thus, are strongly affected by nonlinear strain path changes. Then, data provided in the experimental part of the work was used to assess the existing constitutive equations in the light of their applicability for the prediction of mechanical response of materials subjected to nonlinear loading conditions. In the numerical analysis, work hardening model (i.e. Chaboche model) was investigated. The results of computer simulation were then compared with the DIC measurements and conclusions regarding applicability of the proposed approach were drawn.

The possibility of production of thin-walled castings made of GX2CrNiMoN25-6-3 cast steel was assessed for the exemplary final casting with variable wall thickness. The assessment both of the solidification process of the GX2CrNiMoN25-6-3 alloy and of the final degree of mould cavity filling was done by means of the NovaFlow&Solid program. The body of the casting with its variable wall thickness, including sections thinner than 1 mm, demanded for the appropriate production technology. There are presented the results of technological tests with respect to the application of the centrifugal casting, which confirm the adopted technology of pattern and mould production. The analyzed technology makes possible the production of casting of high surface quality, while simultaneously the yield is increased, and by the same the unit cost of production is lower as compared with the production method used thus far.

A Kampmann-Wagner type numerical precipitation model (KWN) has been implemented using NVIDIA's CUDA framework for numerical programming of the graphics processing unit (GPU). Different implementation strategies are discussed and subjected to performance When the KWN model is used in combination with other calculations that are processed by the CPU, the performance improvements can be such that the KWN model incurs only emph{negligible} additional execution time. Also if the KWN model is used standalone for a large case, the GPU implementation achieves good scalability and performance.measurements. We study two representative cases corresponding to a large and a small workload. The model is found to be well suited for a GPU implementation, provided that there is enough work to keep the device busy and the right parallelization strategy is chosen. For our hardware, we recommend a minimum work load of more than $2^{16}$ histogram bins (as the total of multiple histograms) which corresponds to 146 histogram bins per GPU core.

Evaluation of the possibility of substitution of steel part in the car body by the one made of AZ31 alloy was the objective of the paper. Bracket in the support of the steering wheel was selected for the analysis. Two criteria were selected to evaluate the possibility of using the Mg alloy part: i) stiffness of this part cannot be lower than that of the steel part, ii) Manufacturing of the part has to be possible. The objective of the research was a design of the shape of the bracket, that meets assumed criteria including manufacturing and assembly possibilities. The optimization task was formulated to reach this objective. Maximum stiffness of the part was the objective function and technological limitations were the constraints. Dimensions of the bracket were the optimization variables. Optimal shape was designed and numerical simulations were performed to evaluate possibility of stamping of this part. Simulations have shown that the decrease of the thickness is within of acceptable limits and that the strains are below the limiting strains. Thus, proposition of the shape of the magnesium alloy bracket, which can be safely manufactured by stamping, is the main output of the paper.
Application of significance analysis to finding root causes of product defects in continuous casting of steel
Authors: Rodziewicz Agnieszka , Perzyk Marcin 
Published: August 2023

The aim of this paper is to present an application of the input variable significance analysis to finding probable causes of product defects occurring in continuous casting (CC) of steel. The research was carried out using production data routinely recorded in one of Polish steel plants and basically referred to defective fraction of billets per heat as the process output. The data did not include the cases with zero defects which made the analysis difficult. The process inputs included eight parameters of different nature (physical, organizational and human). For determining which of the process input parameters are crucial for the output and which of them can be easily eliminated in further analyses two different approaches were applied and compared. The basic tool was an MLP-type Artificial Neural Network in which the relative significance was defined as the sum of the absolute weights of the connections from the given input node to all the nodes in the first hidden layer. As a complementary method the one-way analysis of variance (ANOVA) was utilized in which the value of the F-statistics is used as a measure of the input significance. It was found that the both methods indicate that the start-time of the CC process is the factor highly influencing the fraction of defective products. The process physical parameters which are expected to have a large influence on the billet quality, i.e. deviations from nominal casting temperature and deviation from nominal casting speed also appeared to be significant, moreover their variations also highly depend on the start-time of the CC process. The final conclusion is that the direct cause of the defective products are incorrect adjustments of the casting speed occurring mainly in the morning hours, however not correlated with particular operators. This finding can considerably facilitate the identification of the root cause of the defects by the plant engineers. Some recommendations concerning the future work are also given.

Published: August 2023

Rotary forging process, in spite of its various advantages, has still not reached industrial production scale owing to its complex nature. With the advent of sophisticated finite-element modelling capabilities, it is now possible to make rotary forging more predictable and optimize it for industrial production standards.However, modelling by nature involves a series of assumptions and simplifications that can help us make reasonable predictions. It is important to know the important factors that affect the results, and what compromises can be made, with a genuine understanding of what the compromises will result in. This paper reports some initial findings from our attempt towards robust modelling for the design of the rotary forging process. Herein, we have taken the simple case of rotary upsetting of cylinders using a custom-designed rotary forging machine and modelled it using commercial metal-forming software QForm.
