Olímpia a serviço de Germânia: a recepção da arte e da tradição olímpica da Grécia antiga no contexto dos Jogos Olímpicos de Berlim
Authors: Cornelsen Elcio Loureiro
Published: December 2023

Nossa contribuição se destina à apresentação crítica das diversas formas de expressão do discurso nazista no contexto dos XI Jogos Olímpicos, realizados em 1936 na cidade de Berlim, construído a partir da recepção da iconogra?a grega e do ideal olímpico de “paz” que remonta à trégua sagrada que vigorava entre as cidades durante as olimpíadas na Grécia antiga, e do resgate do caráter ritualístico que envolvia os Jogos Olímpicos na sua origem. Partindo de exemplos nos âmbitos do cinema (o “Prólogo” do ?lme Olympia, da cineasta Leni Riefenstahl), das artes plásticas (esculturas que ornamentam o Estádio Olímpico de Berlim, e o Discóbolo, de Myron) e da imprensa (artigos publicados em jornais da época), pretendemos demonstrar na prática as estratégias de manipulação e de persuasão empregadas pelos detentores do poder no intuito de fabricar perante a opinião política internacional uma “ponte” entre a Grécia antiga e a Alemanha nazista como “nação amante da paz”, bem diferente daquela situação vivenciada no dia-a-dia de um Estado totalitário que tinha por fundamentos o expansionismo militar e o racismo.
A abordagem historiográfica das narrativas patriarcais bíblicas
Authors: Cândido Fernando
Published: December 2023

O. O artigo faz uma revisão crítica das diferentes leituras das narrativas do Gênesis, para propor uma abordagem historiográfica mais atual. Em conformidade com a crítica exegética contemporânea, é preciso analisar os textos bíblicos enquanto “monumentos”, priorizando suas condições de produção no período pós-monárquico. Além disso, as reutilizações permanentes das narrativas devem fazer parte da nova agenda do historiador bíblico e, portanto, a literatura midráshica do período rabínico do Judaísmo, torna-se uma importante fonte para os estudiosos do Antigo Testamento
Production of Zn-Ti alloy electrodeposition for biomedical applications
Authors: Bhat Ramesh S.
Published: December 2023

Acidic sulphate bath having ZnSO4, TiSO4 and sulphamic acid, was optimized for the deposition of bright Zn-Ti coating on mild steel. The effect of current density, on deposit characters, such as corrosion rate, thickness, and hardness were discussed. Potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) methods were used to evaluate the corrosion properties of the deposit. The composition of deposits was determined by energy dispersive X-ray (EDX) analysis. Scanning electron microscopy (SEM) was used to examine the surface topography of the deposited layer. Atomic force microscopy (AFM) was used to determine the surface roughness. A new and low-priced sulphate bath, for bright Zn-Ti coatings on mild steel has been proposed, and the results indicate better corrosion resistance properties, and these coatings can be used for biomedical tools like Tuning fork, etc, applications.

Authors: Ristovska Elena Curakova , Genadieva-Dimitrova Magdalena , Todorovska Beti
Published: December 2023

Introduction: The differences in the survival time of cirrhotic patients reported by different studies are probably caused by the influence of many contributing factors. The aim of the study was to evaluate the survival over a one-year period, to register the occurrence of acute decompensation (AD) and to determine the most frequent causes of death.

Material and methods: Out of 71 patients enrolled in the study, 63 completed the prospective one-year follow-up. During the follow-up, we evaluated the occurrence of AD, the causes of death, and we registered three-month, six-month and one-year survival regarding the AD status at presentation.

Results: Of the 63 patients, 24 (38.09%) died before the end of the study (14 patients before the end of three months, 6 before the end of six months and 4 patients before the end of one year). The overall survival was 38.09% and the mean survival time was 108 ± 98.53 days. The most prevalent cause of death was bleeding from esophageal varices (5 patients, 20.83%). AD patients had a significantly shorter survival than patients without AD (97±90.54 vs. 229±138.59) and 78.57% of them died during the follow-up. The estimated six-month and one-year median survival time were 272.8 [95% CI (238.4–307.2)] and 267.1 [95% CI (232.9–301.2)] days, respectively. The six-month and one-year survival were significantly shorter in AD patients (p<0.0001).

Conclusion: The etiology, stage of liver disease and the presence of AD are important factors that influence on the survival in cirrhotic patients.

The incident light on the printed surface undergoes through several processes of scattering, absorbtion and reflection depending on the surface topography and structure of the material. The specular part of the surface reflection is commonly attributed as the geometric component of the reflection, and when measured is associated with specular gloss. The diffuse part of the surface reflection contains the chromatic part of the reflection and is commonly calculated through colorimetric values. Using UV coatings as surface enhacement materials which affect the optical proper-ties of coated surfaces and final appearance of the printed product forms new surface topography over the existing one. We have investigated the influence of three different amounts of UV glossy and matte oveprint coating on the measured specular gloss of printed cardboard samples. The different amount of coatings on the printed samples were achived using three different screen stencils of 180 threads/cm, 150 threads/cm and 120 threads/cm thread count. The cardboard samples were analysed with AFM and SEM microscopes to obtain surface topography and roughness values which were evaluated with the measured geometric values speficied as instrumental gloss. The surfaces with a specific amount of UV coatings showed a new formed topography which influences the reflection of light. The changes in topography were evaluated through surface roughness parameters which showed a decline of surface roughness with tht additional ammount of glossy and matte coatings. The obtained and calculated correlations show there is a high correlation between coating ammount and surface roughness change and gloss for the glossy UV coating. The results for the matte UV coatings showed lower correlation for the gloss and surface roughness.

Continuous work in creating new designer solutions points towards the need to create personal routines as personal communication in the relation comprising design, algorithms, and original computer graphics. This paper shows procedures for developing a control language for creating graphic designs with individual raster elements (screening element obtaint by halftoning). Personal commands should set routines in a language understood by the printer and the designer. The PostScript basis is used because we mix vector and pixel graphics in the same program stream, as well as different colour systems, and our own raster forms. The printing raster is set with the target of special design multi-use, and this includes the field of security graphics and art computer reproduction. Each raster form assumes modifications, creating their raster family. The raster cell content is transformed with PostScript, allowing the setting of basic values, angle and liniature for each pixel separately. Raster cells are mixed in multi-colour graphics to the level of individual designs with variable values of parameters determining them.

To confront with the market need, we have to find alternative in respond to enormous necessity and application of office paper. Therefore, one way in dealing with the problem is to replace or just decrease the use of paper made entirely from primary components, mainly wood fibbers (deciduous and conifer). We analysed mechanical, optical, structural and microscopic properties. Experiments were performed on three conventional and three recycled office papers reachable on the market. Results, obtained from measurements, confirm presumption, that mechanical and surface properties of recycled office paper can be collated and they discern from conventional office paper.

In the era of contemporary and rapid way of life and with advancing digital technology, the display of electronic content on different types of portable devices becomes a part of everyday life. Whether it is on the screen of a Tablet PC, mobile phone or e-book reader, the font needs to be designed in such a way that the displayed message is received and understood as easy and efficiently as possible.When it comes to digital font, intended for display on screen, it is necessary to take into account the properties of the output device and font size to be used. Since the text is intended for display on small screens (especially in case of portable devices), the used font should be adapted to such conditions, namely, it should be designed so as to be readable and legible even at small sizes and at different resolutions of the device.The integral part of contemporary outline fonts are additional instructions on how rasterizer is to render letters at lower resolutions and lower font sizes. These instructions are known as hints, or hint mechanisms, and the process of defining these instructions is called hinting. The aim of this paper is to provide a theoretical basis for understanding the issues of the display of small sizes fonts on screen. The paper will also elaborate the hinting techniques with emphasis on TrueType hint mechanisms that are most suitable for high-quality display on the output device screen, as well as some methods of automatic hinting. Theoretical basis introduced here, represent foundation on which further exploration will lay on. It is important for broadening the knowledge in the field of rasterization and automatic hinting but also for finding new solutions for the simpler and better hinting.

In the recent years many new methods for quality control in graphic industry are proposed. All of these methodshave one in common – using digital camera as a capturing device and appropriate image processing method/algo-rithm to obtain desired information. With the development of new, more accurate sensors, digital cameras became even more dominant and the use of cameras as measuring device became more emphasized. The idea of using cam-era as spectrophotometer is interesting because this kind of measurement would be more economical, faster, widely available and it would provide a possibility of multiple colour capture with a single shot. This can be very usefulfor capturing colour targets for characterization of different properties of a print device. A lot of effort is put into en-abling commercial colour CCD cameras (3 acquisition channels) to obtain enough of the information for reflectancerecovery. Unfortunately, RGB camera was not made with the idea of performing colour measurements but ratherfor producing an image that is visually pleasant for the observer. This somewhat complicates the task and seeks for a development of different algorithms that will estimate the reflectance information from the available RGB cameraresponses with minimal possible error. In this paper three different reflectance estimation algorithms are evaluated(Orthogonal projection,Wiener and optimized Wiener estimation), together with the method for reflectance ap-proximation based on principal component analysis (PCA). The aim was to perform reflectance estimation pixel wise and analyze the performance of some reflectance estimation algorithms locally, at some specific pixels in the image, and globally, on the whole image. Performances of each algorithm were evaluated visually and numerically by obtaining pixel wise colour difference and pixel wise difference of estimated reflectance to the original values. It was concluded that Wiener method gives the best reflectance estimation while produces the best colour fit as well.

This paper presents research regarding application of golden ratio rule in field of product design. The rule was applied to the design on vacuum cleaner, as it is a common and widely spread product. The aim of this paper is to research possibilities of applications of the rule in modern design. In order to determine consumer’s subjective aesthetic judgment of products designed by directly applying golden ratio rule, one vacuum cleaner was designed in that manner. Results for consumer’s subjective aesthetic preference were compared to results for other differently designed vacuum cleaner models present in the market today. Factors used were age, gender and level of education of participants (typical consumer). The results showed no statistical influence of age or gender factors. Statistically significant differences were noticed for level of education factor, between participants with high school diploma and university diploma. It was observed that product de-signed using golden ratio rule received higher marks regarding aesthetics in case of participants with university diploma. It can be concluded that golden ratio rule can be applied in field of product design, equally successful as in the other art fields where it is commonly used, but consumer demographics must be taken in to consideration, especially education level.

Printed textile materials are often exposed to certain external impacts. One of the most common impact, these materials are subjected to, is thermal load. This effect causes certain changes in textile fibers as well as changes of ink colour reproduction printed on these materials. In this paper is presented an investigation of the series of thermal loads effects on print quality parameters of digitally produced impressions on textile substrates. The research includes basic print quality attributes: colour reproduction, macro non-uniformity and quality of line reproduction. Investigation results indicate that by increasing number of thermal loads, bigger changes in colour reproduction occur. Also, the influence of the series of thermal loads on mottle and line reproduction variations is confirmed, as well as the influence of printing substrate characteristics on print quality.

Oriented graph has been drawn in the article according to fixed factors of the quality of applying Braille screen printing on the label by screen UV-varnish-es. Using hierarchical representation of relationships between factors in the form of oriented graphs we have ranked the factors of the screen printing process of Braille elements by UV-varnishes and calculated their corresponding coefficients. We have found that the most ranked are such factors as the surface energy of the printing material, the printing speed, the temperature of UV-varnish and its viscosity. Received results of ranking will enable to synthesize the model of the process’ priority factors and to reveal the possibilities of regulations of geometrical parameters of the tactile font element
Modernisation of Graphic design: the Possibilities and Challenges of digitalisation
Authors:   Taylor’s University, Subang Jaya, Selangor, Malaysi, Poon Stephen T.F.
Published: December 2023

As inventions go, the contrivance of design as a dynamic, fluid, operational vehicle of human technology has always been subject to arguments and debates. The digitalisation of graphic design is a comparatively new field of research, a progressive process that evolves with technological developments. Undoubtedly, the evolution of design practices has transformed the entire design process in ways not deemed possible in the past. The advantages of digitalisation are particularly tangible in the range of possibilities generated by computer-based design tools. The main argument for the increase in “design capital” has been the accessibility of modern art tools to both design practitioners and the wider society, through mass digital culture absorption and the emerging technologies of production and reproduction. In presenting the fundamentals of digitalisation in design practices, this paper retraces the key cornerstones in the evolution of graphic design as an aesthetic medium from the 19th - to 21st -century, while pointing out the expanding, reflexive relationships between design and our environment. The researcher’s aim is to connect the socio-historical developmental frames of social progress and the practical uses of digitalisation in art and design today. The innovations in computer-mediated design work today grew from experimental platforms in the 20th -century, inasmuch as technological diffusion in the 21st -century Information Age derived from the widespread global embrace of the World Wide Web, multimedia and graphical computing systems. As a result of this development of the technological ‘canvas’, the production of design, aesthetic and cultural objects has shifted from the traditional artist-craftsman-specialist paradigm to reflect a more encompassing, diverse scope of ideas fostered by the exposure to different facets of creative capital and inspirations.

The development of wide format inkjet printers made the technology available for large area commercials. Outdoor advertising uses a wide range of substrate including paperboard, vinyl, canvas, mesh; the material of the substrate itself has to endure the physical and chemical effects of local weather. Weather elements (humidity, wind, solar irradiation) degrade print-ed products inevitably; plastic products have better resistance against them, than paper based substrates. Service life of the printed product for outdoor application is a key parameter from the customer’s point of view. There are two ways to estimate expected lifetime: on site outdoor testing or laboratory testing. In both cases weathering parameters can be monitored, however laboratory testing devices may produce the desired environmental effects and thus accelerate the aging process.Our research objective was to evaluate the effects of artificial weathering on prints produced by inkjet technology on plastic substrates. We used a large format CMYK inkjet printer (Mutoh Rockhopper II, with Epson DX 4 print heads) to print our test chart on two similar substrates (PVC coated tarpaulins) with grammages 400 g/m2 and 440 g/m2.Specimen were aged in an Atlas Suntest XLS+ material tester device for equal time intervals. We measured and calculated the gradual changes of the optical properties (optical density, tone value, colour shifts) of the test prints.

3D scanning of physical objects is one of the frequently used methods for generating input data for 3D printing process. Close-range photogrammetry represents a cost-efficient alternative to conventional 3D scanning. However, one of the basic problems in application of this method is accuracy, espe-cially in the case of small objects with complex geometry. In this case study, a 3D-printed object of small dimensions was used to test the accuracy and precision of close-range photogrammetry. CAD Inspection was used to obtain measurements of the scanned model and compare it with the original CAD model, while the results were statistically analyzed. The results of statistical analysis showed that the scanning accuracy in this experiment did not depend on the particular cross-section of the model, while the precision of 3D scanning depended on the selection of cross-sectional profile curve.

One of the missions of Islam is to glorify women and put them in a respectable position, so that they can reach the status of pious women. Actually, the mission of Islam has been achieved in the time of the prophet Muhammad SAW and how many decades after that still make the Qur’an as a way of the life. However, the reality of life in modern times today shows an alarming fact. Many Muslim women have experienced moral decadence. Many Muslim women today fall into acts that are prohibited by religion, such as courtship, adultery, and others. Sinful acts like this cause them to be far from the category of pious women. Whereas if they were asked to choose to be a pious woman or a pious woman, of course the answer from the bottom of their hearts would be to choose a pious woman. Women are glorified in Islam because of their role and position as child, wife, and mother. Because Islam really maintains the dignity of a woman well. The most high ranking woman is a pious woman who always istiqamah in carryng out all the commands of Allah and staying away from all the prohibitios. The formulation of the problem of this research is how the concept of pious women in the interpretation of Al-Azhar, the aim is to find out the aim is to find out the concept of pious women in the interpretation of Al-Azhar. This type of research is library research, namely research through library research, gathering techniques by searcing for verses about pious women. Based on the interpretation approach, which is done by the workings of the tahlili method. The results of this study are shalihah women can be said to be women who maintain their eyes, are consistent in covering their genitals, women who have strong personalities, women who are obedient and intelligent, and women who maintain their chastity.
Carbonates thermal decomposition kinetics and their implications in using Rock-Eval® analysis for carbonates identification and quantification

Published: December 2023

In 2014, Pillot et al. [Identification and quantification of carbonate species using Rock-Eval pyrolysis, Oil Gas Sci. Technol. – Rev. IFP 69, 341–349. https://doi.org/10.2516/ogst/2012036] proposed to use the Rock-Eval® method as a reliable tool to identify and quantify carbonates in solid samples from the CO2 flux emitted by their progressive thermal decomposition during programmed heating under oxidant atmosphere. Nevertheless, several phenomena associated with the thermal decomposition of carbonates were not explained by these authors. This paper attempts to explain these phenomena by adding 5 new carbonate species to the 9 studied by Pillot et al. https://doi.org/10.2516/ogst/2012036 and by developing a kinetic approach to the thermal decomposition of carbonates. It appears that the kinetics of thermal decomposition of most carbonates is not of order 1 but varies according to carbonate species. Consequently, the thermal decomposition temperature varies with both the sample weight and the temperature rate applied. The thermal stability of simple carbonates is explained by the electronegativity of the cations associated with the carbonate anion. Our study provides further insights into the use of Rock-Eval® for the identification and quantification of different carbonate species.

Objectives:

The objective of this study was to investigate renal function after robot-assisted partial nephrectomy (RAPN) and percutaneous cryoablation (PCA) in clinical stage T1 (cT1) renal cell carcinoma (RCC) and evaluate the relationship between baseline renal function and renal functional outcome.

Material and Methods:

Patients with cT1 RCC treated with RAPN or PCA were prospectively enrolled between June 2019 and January 2021. Renal function was evaluated using estimated glomerular filtration rate, Tc-99m diethylenetriamine-pentaacetate plasma clearance, Tc-99m mercaptoacetyltriglycine renography, and renal volume at baseline and 6 months after treatment.

Results:

Fifty-six patients were included (18 RAPN, 38 PCA). PCA patients had a significantly higher age (68.5 years; P = 0.019) and Charlson comorbidity index (3.0; P = 0.007). Tumor characteristics did not differ significantly between RAPN and PCA. Total renal volume decreased significantly after PCA (−18.2 cm3; P = 0.001). Baseline chronic disease stage IIIb–IV leads to a greater reduction in renal volume (−31.8 cm3; P = 0.003) but not other renal function measures. Renal function declined significantly after either treatment without significant differences between RAPN and PCA.

Conclusion:

This study found a small, similar decrease in renal function 6 months after RAPN or PCA, despite significant differences in baseline patient characteristics. Reduced renal function at baseline did not lead to a worse renal functional outcome.

Plasmonic sensors are candidates for numerous clinical applications, but few examples demonstrate their performance on large sample cohorts, a necessary step for clinical translation. The COVID-19 pandemic provided an unprecedented opportunity to validate a surface plasmon resonance (SPR) sensor for SARS-CoV-2 inhibition with a cohort of over 1,000 clinical samples from the longitudinal study of a food and retail worker population. The SPR sensor provided an in vitro model to assess the level of neutralizing antibodies by measuring the inhibition of the SARS-CoV-2 spike protein interaction with ACE-2 following exposure of the spike protein to naive and immune sera (from vaccination and/or infection). In conjunction with population data on vaccination and infection, and epidemiological data from the local jurisdiction of the study cohort, it is shown that the SPR sensor performed well in assessing the level of “pseudo-neutralization” of participant sera and that the response of the SPR sensor correlates (r = 0.74) with a live virus microneutralization assay as well as with metadata of relevant events (vaccination, waves of infection, etc.) that occurred during the study period. Using these data, the article details the challenges and opportunities of using plasmonic sensors in clinical practice.

Introduction of an alkylsulfonic acid moiety into the side chain of polythiophene was carried out. Synthesis of 2,5-dihalothiophene bearing an alkylsulfonate group at the 3-position was performed. The reaction of 2-chloro-5-iodothiophene with a Grignard reagent to form organometallic monomer of the corresponding thiophene followed by nickel(II)-catalyzed cross-coupling polymerization lead to head-to-tail-type regioregular polythiophene. The ester group at the side chain was converted into alkali metal sulfonate by treatment with NaI or metal hydroxides (Li, Na, K). The obtained metal salts were successfully transformed to sulfonic acid by the treatment with ion exchange resin. The electric conductivity of the regioregular polythiophene bearing sulfonic acid was remarkably improved ca. 102 times from the corresponding metal salts. (106 times higher than sulfonate ester)

Manipulating the three-dimensional (3D) structures of cells is important for facilitating to repair or regenerate tissues. A self-assembly system of cells with cellulose nanofibers (CNFs) and concentrated polymer brushes (CPBs) has been developed to fabricate various cell 3D structures. To further generate tissues at an implantable level, it is necessary to carry out a large number of experiments using different cell culture conditions and material properties; however this is practically intractable. To address this issue, we present a graph neural network-based simulator (GNS) that can be trained by using assembly process images to predict the assembly status of future time steps. A total of 24 (25 steps) time-series images were recorded (four repeats for each of six different conditions), and each image was transformed into a graph by regarding the cells as nodes and the connecting neighboring cells as edges. Using the obtained data, the performances of the GNS were examined under three scenarios (i.e. changing a pair of the training and testing data) to verify the possibility of using the GNS as a predictor for further time steps. It was confirmed that the GNS could reasonably reproduce the assembly process, even under the toughest scenario, in which the experimental conditions differed between the training and testing data. Practically, this means that the GNS trained by the first 24 hour images could predict the cell types obtained three weeks later. This result could reduce the number of experiments required to find the optimal conditions for generating cells with desired 3D structures. Ultimately, our approach could accelerate progress in regenerative medicine.

Computational techniques for predicting molecular properties are emerging as pivotal components for streamlining drug development, optimizing time, and financial investments. Here, we introduce ChemLM, a transformer language model-based approach for this task. ChemLM further leverages self-supervised domain adaptation on chemical molecules to enhance its predictive performance across new domains of interest. Within the framework of ChemLM, chemical compounds are conceptualized as sentences composed of distinct chemical ‘words’, which are employed for training a specialized chemical language model. On the standard benchmark datasets, ChemLM has either matched or surpassed the performance of current state-of-the-art methods. Furthermore, we evaluated the effectiveness of ChemLM in identifying highly potent pathoblockers targeting Pseudomonas aeruginosa (PA), a pathogen that has shown an increased prevalence of multidrug-resistant strains and has been identified as a critical priority for the development of new medications. ChemLM demonstrated significantly higher accuracy in identifying highly potent pathoblockers against PA when compared to state-of-the-art approaches. An intrinsic evaluation demonstrated the consistency of the chemical language model’s representation concerning chemical properties. Our results from benchmarking, experimental data, and intrinsic analysis of the ChemLM space confirm the wide applicability of ChemLM for enhancing molecular property prediction within the chemical domain.
