Authors: Sarmiento Acosta Nathaly , Peinado Acevedo Juan Sebastian , Cadena Afanador Laura del Pilar
Published: January 2023

El formaldehído (FA) se utiliza en la preservación de muestras anatómicas. En el programa académico de Medicina se utilizan diversos especímenes preservados con él para el aprendizaje de la Anatomía y la Patología. Durante las prácticas con dichos especímenes es frecuente que haya emisión vapores y contacto directo con el FA, lo que implica niveles altos de exposición; se han informado diversos síntomas según la vía de exposición, más frecuentemente respiratorios y de la piel. Por consiguiente, el FA constituye un riesgo ocupacional para la salud de profesionales y estudiantes cuyas actividades los exponen a él. Este artículo es una revisión de la literatura actual sobre las bases fisiopatológicas y las manifestaciones clínicas asociadas a la exposición a FA en ámbitos académicos, especialmente en estudiantes de Medicina; se incluyen además las medidas de protección.
Level Playing Field or Politics as Usual? Equalization–Normalization in Direct Democratic Online Campaigns
Authors: Fischer Michaela , Gilardi Fabrizio
Published: January 2023

Are digital technologies leveling the playing field or reinforcing existing power relations and structures? This question lies at the core of the equalization vs. normalization debate. The equalization thesis states that the affordances of digital technologies help less-powerful political actors to compete with their more resource-rich counterparts, thereby overcoming structural disadvantages inherent to the political landscape. The normalization thesis, in contrast, suggests that more powerful and resource-rich political actors outperform their weaker competitors in the digital sphere by establishing a more sophisticated online presence, thus reproducing existing power imbalances. An overwhelming majority of studies on the equalizing vs. normalizing effect of digital technologies focus on electoral campaigns or non-electoral periods. Direct democratic campaigns have not been adequately considered in previous studies. This study exploits the regularly held and institutionalized character of direct democratic votes in Switzerland. Specifically, it investigates political actors’ level of activity and generated engagement on Facebook and in newspapers during all direct democratic campaigns from 2010–2020. Applying the equalization vs. normalization lens to Swiss direct democratic campaigns over an 11-year timespan provides new insights into the status-quo preserving or altering effects of digital technologies. We find a tendency toward equalization in terms of Facebook activity and user engagement, and in a comparative perspective: Facebook campaigns are, on average, more balanced than newspaper advertisement campaigns, particularly since 2014.
Beyond Brexit? Public Participation in Decision-Making on Campaign Data During and After Referendum Campaigns
Authors: Rone Julia
Published: January 2023

While the Brexit referendum campaign has been extensively researched, media, regulatory bodies, and academics have often talked at cross-purposes. A strong focus on Cambridge Analytica’s role in the 2016 referendum, despite official investigations concluding the company had only limited involvement in the campaign, has distracted attention from more mundane but highly controversial data practices, including selling voters’ data to third parties or re-using campaign data without consent from data subjects. This empirical case study of data-driven referendum campaigning around Brexit raises two broader theoretical questions: First, moving beyond the current focus on transparency and accountability, can public participation in the ownership and management of campaign data address some of the problematic data practices outlined? Second, most academic literature on data-driven campaigning, in general, and referendum campaigns, in particular, has often overlooked the key question of what happens with campaigning data once campaigns are over. What legal safeguards or mechanisms of accountability and participation are there to guarantee consent when it comes to further re-use of people’s data gathered during campaigns? Ultimately, the article raises the question of who should have a say in how “people’s data” is used in referendum campaigns and afterwards and makes a case for democratising such decisions.

Aim: Antimicrobial resistance in bacteria is one of the most discussed and important theme in healthcare field now. Bacteriophages are known as the most promising alternative to antibiotics and a method of fighting the multi-resistant pathogens. In this study, our main aim was to isolate lytic specific phages of multidrug resistant Pseudomonas aeruginosa, one of the most dangerous bacterial human pathogens. Methods: Disk-diffusion method, spot-test, agar overlay method, electron microscopy. Results: Antimicrobial resistance range of P. aeruginosa 458 strain was tested and it appeared to be resistant to all available antibiotics. Phages were isolated from waste waters in Kyiv. They appeared to have a typical morphology of Myoviridae family. Isolated viruses successfully lysed all the bacteria in vitro. Conclusions: Considering high effectiveness of isolated phage in vitro, we propose it as a candidate for phage therapy, though further studies on physical and genetic characteristics are required.
Prosecutor’s Legal Standing at Pre-Trial Stages of the Criminal Proceedings of the Russian Empire before the Judicial Reform of 1864
Authors: Gorbachev V. P.
Published: January 2023

To understand the essence of transformations in the Prosecutor’s Office of the Russian Empire that took place as a result of the Judicial Reform of 1864, it is necessary to clarify the legal situation and the actual role of the Prosecutor’s Office during the pre-reform period. In this regard, the paper analyzes functions of the Prosecutor’s Office that were assigned to the Prosecutor’s Office before the Judicial Reform. The author explains relationships between prosecutors and attorneys-scriveners and the provincial administration and shows their actual dependence (as well as legal dependance for an attorney-scrivener) upon the administration. The author investigates the attempts of the Ministry of Justice at the legislative level to provide for the independence of attorneys-scriveners from governors and provincial boards with their subordination only to provincial prosecutors. The paper elucidates the content of the supervisory function of the prosecutor’s office that was the main function of the Prosecutor’s Office. Activities of the Prosecutor’s Office in the field of criminal procedure constituted an insignificant part of all its activities. At the same time, the powers of the prosecutor in the criminal process were limited. The study shows that at the pre-trial stages of the criminal procedure, prosecutors and solicitors were in charge of crime detection, supervision over investigation and care of detainees. The prosecution function of the prosecutor’s office was not completed and involved initiating criminal prosecution before the provincial administration. The criminal investigation function of the Prosecutor’s Office was limited. To supervise investigation, the Prosecutor’s Office was given certain powers that were carried out in parallel with the supervisory powers of the governors. Moreover, the prosecutor’s supervision was of secondary importance compared to the supervision exercised by governors, who plaid the main leadership and supervisory role in the criminal process. It is shown that during the pre-reform period, due to the large number of general supervisory duties, the supervision over criminal investigation was formal and unsatisfactory.

Authors: Artemov V. M.
Published: January 2023

The study elucidates historical and logical necessity of an ethical and philosophical dimension of law in the form of an ethical examination of applied problems and situations (especially in relation to law) arising in the context of new technological threats. The author dwells on the paradigm of the upward development of society and protection of human rights not in the context of an individualistic dominant of the Western type, but in the context of priority of preserving, developing and improving society as a whole in the direction of a high ideal that presupposes restoration of justice based on true knowledge of the real state of affairs. It is suggested that the goodwill of those who perform the work demanded by society constitutes the necessary condition. The paper describes the specification of its methodology understood in the broad sense of the word, when ethics is considered as the pinnacle of philosophy. The author concludes that the strategy of strengthening morality in law is not only in demand, even salutary, for society as a whole and for every one. Morality is such a phenomenon that you need to constantly and purposefully work with.

Authors: Osipov A. L.
Published: January 2023

The paper discusses the issues of understanding the terms that make up the right to privacy and protection of private communications between individuals in criminal proceedings. The author studies the current state of legal regulation and the problems related to the implementation of this right in obtaining evidence in criminal cases. The paper analyzes the algorithms of judicial control over the legality of the restriction of the constitutional right to the inviolability of private communications using foreign doctrines of «necessity (restrictions) in a democratic society», as well as «expectation of privacy test». The foreign experience of resolving these issues within the framework of various legal systems, including the practice of the ECtHR, is considered. The problem of judicial authorization of access to data in the electronic memory of subscriber devices in the course of various investigative actions is scrutinized. Based on the findings, the author proposes to improve the national legal regulation of procedures for monitoring the legality of restricting the right of citizens to the inviolability of their private communications in criminal proceedings, as well as to improve the guarantees for the application of these procedures in judicial practice.
Methodological Approach to Determining the Place of Forensic Appraisals in Classification of Forensic Economic Expertise
Authors: Ivliev A. D.
Published: January 2023

At present, forensic appraisal does not have a sufficient theoretical basis. This brings about more and more questions among the expert community about what type, genus and even class this forensic examination belongs to. Without theoretical foundations, forensic examination cannot be included in the existing classifications, because there is no consensus on what is meant by its subject and tasks, and also what should be attributed to the objects of forensic evaluation. The paper analyzes the works of scientists who cover theoretical foundations of forensic appraisals and outlines the author’s position on the topic. The author notes that today in the scientific and expert community there is no consensus on the theoretical aspects of forensic appraisal. Based on the results of the study, the author’s definition of the subject is proposed, tasks are formulated and the distinctive features of the objects of forensic appraisals are described. Attention is given to digital objects of expert research within the framework of both civil, arbitration and criminal proceedings.

Published: January 2023

Large-scale skin injuries are usually accompanied by impaired wound healing, resulting in scar formation, or significant morbidity and mortality. The aim of this study is to explore the in vivo application of 3D-printed tissue-engineered skin substitute using innovative biomaterial loaded with human adipose-derived stem cells (hADSCs) in wound healing. Adipose tissue was decellularized, and extracellular matrix components were lyophilized and solubilized to obtain adipose tissue decellularized extracellular matrix (dECM) pre-gel. The newly designed biomaterial is composed of adipose tissue dECM pre-gel, methacrylated gelatin (GelMA), and methacrylated hyaluronic acid (HAMA). Rheological measurement was performed to evaluate the phase-transition temperature and the storage and loss modulus at this temperature. Tissue-engineered skin substitute loaded with hADSCs was fabricated by 3D printing. We used nude mice to establish full-thickness skin wound healing model and divided them into four groups randomly: (A) Full-thickness skin graft treatment group, (B) 3D-bioprinted skin substitute treatment group as the experimental group, (C) microskin graft treatment group, and (D) control group. The amount of DNA in each milligram of dECM was 24.5 ± 7.1 ng, fulfilling the currently accepted decellularization criteria. The solubilized adipose tissue dECM was thermo-sensitive biomaterial and underwent a sol-gel phase transition when temperature rises. The dECM-GelMA-HAMA precursor undergoes a gel-sol phase transition at 17.5°C, where the storage and loss modulus of the precursor is about 8 Pa. The scanning electron microscope showed that the interior of crosslinked dECM-GelMA-HAMA hydrogel is 3D porous network structure with suitable porosity and pore size. The shape of the skin substitute is stable with regular grid-like scaffold structure. Wound healing in the experimented animals was accelerated after being treated with 3D-printed skin substitute, which attenuate inflammatory response, increase blood perfusion around the wound, as well as promote re-epithelialization, collagen deposition and alignment, and angiogenesis. In summary, 3D-printed dECM-GelMA-HAMA tissue-engineered skin substitute loaded with hADSCs, which can be fabricated by 3D printing, can accelerate wound healing and improve healing quality by promoting angiogenesis. The hADSCs and the stable 3D-printed stereoscopic grid-like scaffold structure play a critical role in promoting wound healing.

Authors: ANTIL Surender , SACHDEVA Gulshan , SHARMA Avdhesh
Published: January 2023

A gasifier employs partial ignition of biomass and conversion to gaseous fuels of high calorific value. Bubbling fluidized bed gasifier is a promising one amongst other gasification technologies like fixed bed, entrained flow etc. It has several noteworthy advantages like large- and small-scale applications, efficient heat and mass transfer rates due its fuel flexibility, low capital and operating costs, etc. However, low mixing rate of biomass feedstock and gasifying agent, high tar content in the product gas and low calorific value of producer gas are some of its limitations which need sincere attention to enhance its performance. The present study analyzes the effect of design variables of the proposed gasifier reactor for different feedstock along with the operating variables on the quality of producer gas. This review paper examines the present global status of biofuels, different types of gasification technologies, approaches adopted for the gasification, different parameters affecting gasification performance, enhancement of product gas conditioning, technical and cost-effective viability and the future prospects of gasification.

In addition, this study explains the Theory of Planned behavior and additional two variables, namely Islamic religiosity and willingness.The Partial Least Square Structural equation modeling (SEM) approach is used to test structural models and measurements. Online questionnaires were distributed to purposively selected respondents throughout Indonesia, which consists of all major islands. In total, there are 104 respondents collected. This study found that the Attitude variable and the willingness variable affect the intention to pay cash waqf among Indonesian Muslim youth. In addition, Subjective Norms, Perceived Behavioral Contol, and Islamic religiosity variables are not significantly proven as the determinant. This study focuses on the factors that influence the intention of Indonesian Muslim youth to perform cash waqf. This study examines the theory of planned behavior, Islamic religiosity, and willingness. With the latest data and variables studied, these findings can be used as guidelines for policymakers, especially waqf bodies to innovate and improve the characteristics of cash waqf contributors, especially among Muslim youth so that they can maintain sustainability and development of waqf instruments.
Cash Waqf Acceptance Among Entrepreneurs in Kano Metropolis, Nigeria
Authors: Muhammad Aliyu Dahiru , Alkassim Jibril Lawan , Sulaiman Sagir Muhammad
Published: January 2023

Cash waqf was introduced as an alternative for individuals who do not have an immovable asset but rather have the cash to donate as waqf. It can be observed, however, that Muslims in Kano State narrow their perception of waqf only to be in the form of a kind but not in cash. It is to say that public awareness and understanding of cash waqf are insignificant. Therefore, this study aims to assess factors influencing the intention to accept cash waqf among entrepreneurs in the Kano metropolis with particular reference to Singer Market. The study employed partial least square–structural equation modeling (PLS-SEM) and was theoretically guided by the Theory of Planned Behavior (TPB). Structured survey questionnaires were administered to 379 respondents whom were registered entrepreneurs in Singer Market based on a convenience non-probability sampling technique. Descriptive statistics using charts and tables were employed to analyze the demographic information, while data collected from the respondents were analyzed utilizing AMOS, version 21. The study uncovered that perceived behavioral control and religiosity significantly influenced the intention to accept cash waqf among entrepreneurs in Singer Market in Kano Metropolis, while awareness and attitude did not. This paper recommends that the management of the Kano State Zakat and Hubsi Commission (KSZHC) should establish sensitization programs to create awareness and promote cash waqf for the public to mobilize more potential waqf donors in the state.
Repertorios iconográficos y modalidades textuales.
Authors: Trabado-Cabado José-Manuel
Published: January 2023

Este artículo pretende estudiar las diferentes estrategias para encontrar un lenguaje que exprese sentimientos traumáticos. Se centra en la obra de Emile Ferris Lo que más me  gusta son los monstruos y en Una entre muchas de Una. El análisis está estructurado en dos niveles: por un lado, la construcción de repertorios iconográficos que configuran visualmente la historia y, por otro lado, las modalidades textuales concebidas como un dispositivo para organizar el texto y otorgarle significado al discurso. Mientras que Emil Ferris usa lo que podríamos denominar una especie de Koiné gráfica enraizada en las convenciones de las películas y cómics de terror, Una crea un nuevo código gráfico para dibujar imágenes simbólicas que son válidas solo para ese contexto: crea un idiolecto gráfico. Lo que me más gusta son los monstruos está construido sobre formas textuales como el diario y la historia policíaca mientras que Una entre muchas se vale de las formas del reportaje y de los textos de no ficción. Ambos hechos tienen su repercusión en el aspecto visual de las historias y regulan las condiciones de lectura.
Rejecting the Plea for Modesty. Kant’s Truth-Directed Transcendental Argument Based on Self-Consciousness of Our Own Existence
Authors: de Sá Pereira Roberto Horácio
Published: January 2023

Recent developments of transcendental arguments reflect the struggle to accommodate Stroud’s devastating objection by giving up of failed expectations in providing a proof of what the external-world skeptic calls into question: knowledge of the existence of the outside world. Since Strawson capitulation in 1984, the truth-direct transcendental arguments gave way to modest belief-direct transcendental arguments that concedes that truth-direct transcendental arguments are doomed to fail to establish ambitious conclusions about reality, but at the same time hold that they can nonetheless successfully establish modest conceptual connection between the major beliefs within our conceptual scheme. This article seeks the “reactionary” rehabilitation of the old hubris: a new defense of the truth-direct transcendental argument. I set forth a new reconstruction of Kant’s Refutation as successful truth-directed transcendental argument that meets Stroud’s objection. As several papers and books about the theme, this article is of a systematic and of a historical nature by connecting the contemporary debate about transcendental argument with Kant’ philosophy.

One of the efforts to encourage sustainable agricultural development is by developing potential commodities so that scenarios can be drawn up that are in accordance with the region's potential. Optimum land use scenarios with several constraint targets need to be prepared by considering food needs, ecological sustainability, and farm income. This study aims to identify land available for food commodities and simulate the land use allocation of food commodities in Purwakarta Regency to meet food needs, farm income, and tolerance for erosion. Location quotient index, shift-share analysis, land suitability & capability analysis, and Multiple Goals Programming were used to achieve research objectives. The identified leading commodities are peanuts, cassava, and sweet potato. We suggest 15 classes of land available for optimum land use allocation. Space optimization is organized into four scenarios considering erosion control targets, meeting farmers' minimum incomes, and rice production. The smallest erosion is 13,159 tons/ha/year, while the highest possible income is IDR300,500,000,000. The highest rice production is 202.070 tonsGKP, cassava production is 16,919 tons, sweet potato is 2.014 tons, and peanut production is 531 tons.

Published: January 2023

The number of businesses like coffee shops (warkop) in Banda Aceh City makes every business actor required to implement the right strategy in capturing the hearts of consumers so that they can continue to visit that the company's income can increase. Therefore, this study aims to analyze consumer interest in choosing warkop in Banda Aceh City so that business actors can use the information obtained in making decisions to be applied to their business. The observation locations were carried out in five coffee shops. Based on the results of the study, several factors become a reference for consumers in choosing the warkop to visit, including location, place, price, internet, parking facilities, and mushalla. However, in some coffee shops, there are also problems in providing quality services, such as delays in the handling process, slight menu variations, the noise of places, parking lots, and less strategic locations. Thus, if the problem is not addressed properly, it is estimated that it can have an impact on the nature of the next consumer. With a soft systems methodology (SSM) approach, these problems can be overcome. SSM can build a conceptual model that can formulate a strategy for warkop business actors in Banda Aceh City. SSM method results in two suggested recommendation activities. First, technical recommendations, namely that business actors must make efforts in improving their companies, such as determining strategic locations, setting competitive prices, providing adequate parking space, and fixing various other factors. Second, policy recommendations include establishing special SOPs, developing human service resources, incorporating local wisdom, and innovating. So applying these two activity recommendations can provide answers to problems.

This study aimed to estimate the level of efficiency and socio-economic factors that predispose the technical efficiency of shallot farming in Aceh Province based on differences in growing seasons. The data analysis method was estimated using the Stochastic Frontier Cobb-Douglas production function with the maximum likelihood estimation (MLE) approach. The 2014 Horticultural Crops Household survey data from the Central Statistics Agency (BPS). The number of samples was 143 shallot farming units. The results showed that seed production, fertilizer, labor, and the harvested area positively and significantly affected shallot output. Shallot farming in this province has been efficient at around 85,09%. Based on the growing season, the value of efficiency in the dry season is 90,08%, which is more efficient than farming in the rainy season, which is 70,03%. However, the technical efficiency value of shallots in the dry season and rainy season can still be improved. In addition to seasonal variables, significant factors affecting the efficiency of shallots are participation in farmer groups and land type, while education and seed sources have no considerable effect. The government's role is to provide quality seeds and conduct cultivation during the dry season to increase the technical efficiency of shallot farming.   Keywords: farmer group, season, stochastic frontier, technical efficiency

This study aims to determine the effect of various doses of rice husk biochar combined with organic amendments of cow manure and inorganic amendments of recommended fertilizer packages (urea, TSP, and KCl) on acid-sulfate soils. Over four months, the study was conducted in the Experimental Land of the Center for the Assessment of Agricultural Technology (BPTP) Pal IX, West Kalimantan Province. The study employed a randomized block design, with treatments including control soil, rice husk biochar 6 t ha-1, rice husk biochar 8 t ha-1, rice husk biochar 10 t ha-1, rice husk biochar 12 t ha-1, package of recommended inorganic fertilizer, package of recommended inorganic fertilizer + rice husk biochar 10 t ha-1, manure 10 t ha-1, and 10 t ha-1 + rice husk biochar 10 t ha-1. The findings revealed that single rice husk biochar amendments and their combination with inorganic and organic amendments had varying effects on the improvement of several physical properties of acid sulfate soils (density, total pore, moisture content, and penetration resistance). The amendment of a single biochar with a dose of 12 t ha-1 resulted in the lowest bulk density of acid sulfate soil, which decreased by 16% compared to the control soil. At a dose of 12 t ha-1, rice husk biochar produced the highest porosity and soil moisture content, 55% and 17%, respectively. The soil strength, as measured by the lowest penetration resistance, decreased by 30% in the treatment of manure 10 t ha-1 + biochar 10 t ha-1 (350 N cm-2) compared to the control soil.

Published: January 2023

PT Pupuk Sriwidjaja Palembang (PSP) produces 1,222 tons fly ash per month from the operation of a coal boiler with a capacity of 1x23 MW. Fly ash has potential physical properties and mineral content. The Government Regulation No.22 of 2021, which classifies fly ash as a non-B3 waste, open up opportunities to utilize fly ash in a fertilizer product. In this project, the development of NPK 15-10-12 fertilizer with fly ash as a filler and fertilizer testing on tomato plants has been conducted. The use of fly ash as a filler in the granulation process has no effect on crushing strength and nutrient content of N, P, and K. The effects of using fly ash in the granulation process are in the consumption of water and in the granule drying process. The greater the ratio of fly ash the more water needed in the granulation process and eventually causes an increase in the moisture content in the final product. From the results of fertilizer test on tomato plants on the parameters of plant height, plant diameter, and fruit weight, the use of NPK with fly ash-filler did not give a significant difference compared to the use of NPK without fly ash. The use of fly ash as a filler also does not give any influence on the content of heavy metals in the fruit of tomato. Increase in pH of soil are observed in fertilization to NPK 15-10-12 using fly ash fillers.

It is shown that an examination of reduced galvanostatic charge-discharge curves allows making preliminary conclusion on degradation mechanism upon cycling. If such degradation is due to loss of active material all normalized curves coincide. In the case of insulating films building up normalized curves are shifted along potential axis. Various structure changes result in qualitative change of curves shape.

The electrode behavior of various fluorinated graphite materials and different conductive additives in various electrolytes are studied. Fluorocarbon materials based on graphite fibers are shown to have the best discharge characteristics. The advantage of thin cathodes based on fluorinated nanomaterials with a solid polymer electrolyte in comparison with the similar electrodes with traditional fluorocarbon active material is demonstrated. The use of fluorinated nanomaterials results in increased discharge characteristics of the cells.

The paper treats effective formation of lead-acid batteries with pulse asymmetric current with the aid of a specially designed source of powerful pulses getting through a transformer from a 50 Hz alternating supply line. Our mode of formation with pulse asymmetric current provides a reduced gas release and low electrolyte heating. On the basis of the dependence of the electrolyte density on the first-cycle formation duration, a conclusion has been made of more effective formation of batteries being charged with pulse asymmetric current with frequencies of 25 and 50 Hz. The found linear dependence of the electrolyte density of a formed lead-acid battery on its discharging degree enables electrolyte density to be used as an objective estimation of the battery charging degree.

Nahdlatul Ulama as the largest community organization in Indonesia and has been established for a long time has experienced various ups and downs in each of its journeys. The purpose of this study is to describe and analyze the Ups and Downs of Nahdlatul Ulama's Relationship with the Dutch East Indies Government 1926-1942. This research is a literature study, where the sources of penetilitin come from old texts in the regions and Jakarta, sources in the regions rely more on the private collections of some kyai over the literature related to this research. Tracing sources located in Jakarta include the National Archives, the National Library, and LAKPESDAM NU. The stage of this research is the collection of information from all sources, criticisms and interpretations. The process of collecting information from the whole source (heuristics), selection of materials, criticism and subsequent interpretation is needed to carry out historical synthesis. Historical synthesis is the embodiment of the ability to think logically and the ability of a historian's historical imagination so that the characteristics of a certain model of historical work are visible. The results of this study show that  there was a ups and downs in the relationship between Nahdlatul Ulama and the Dutch East Indies government, when the Dutch East Indies government implemented a Neutral Religion policy among traditionalist Islamists, there was not too much friction with the Dutch East Indies government because the government guaranteed that there was no interference in Islamic religious affairs, even the government formed a Raad Agama (Religious Court) and was led by a religious and expert ruler.  Islam. Protests, non-cooperative resistance with the Dutch East Indies government began to be carried out by Nahdlatul Ulama when the practice of religiously neutral politics was violated by the government by making various ordinances that harmed Muslims. However, several times Nahdlatul Ulama still praised the muji of the Dutch East Indies government because several HBNO requests were granted by the government, such as the non-enactment of the rules for brides-to-be to be examined in Raad Agama, and the non-imposition of duties on the slaughter of sacrificial animals. However, at the end of the Dutch East Indies government, Nahdlatul Ulama really felt pro-Japanese

ResumoAs obras das artistas Rosana Paulino e Aline Motta levantam o debate sobre o apagamento da memória da cultura negra na sociedade brasileira, uma sociedade em que perdura o racismo advindo de nosso processo histórico, perpassado por mais de 300 anos de escravagismo. São artistas em cujos trabalhos estão presentes também a vontade de cura dos traumas herdados, uma cura que estaria no enfrentamento e retomada da ancestralidade.AbstractThe works of artists Rosana Paulino and Aline Motta raise the debate about the erasure of the memory of black culture in Brazilian society, a society where racism persists arising from our historical process, permeated by more than three hundred years of slavery. They are artists whose works also contain the desire to heal inherited traumas, a healing that would be in the confrontation and resumption of ancestry.

This study presents the preparation of short glass fiber reinforced polypropylene (PP/FG) composites using with waste (post-consumer) polypropylene composite containing long glass fiber (PP/LFG) obtained from the recycling of battery covers of trucks. Waste PP/LFG composite parts were mechanically grinded before adding to PP/FG composites. An injection molding machine was used to produce the PP/FG composite test samples loading with recycled waste PP/LFG composite in the range of 1-20% by weight. Effects of recycled waste PP/LFG content on the mechanical, thermal, and morphological properties of the PP/FG composites were investigated. The following three different tests, at various waste PP/LFG ratios, were conducted: Izod/Charpy Impact test, bending test, and tensile test. Mechanical test results showed that mechanical strength of prepared PP/FG composites were not influenced by content of waste PP/LFG material up to 10 wt.%. Differential scanning calorimetry (DSC) was used for the evaluation of thermal parameters such as melting point and crystallization temperature of the polymer matrix in the composites studied. Furthermore, by analyzing the values of thermal effects determined using the DSC method, it was possible to determine the degree of crystallinity. The DSC results showed that crystallinity %, melting, and crystallization temperatures of PP/FG composites were not influenced to adding waste PP/LFG at different ratios. The morphology of composite materials was investigated by SEM analysis. Good fiber dispersion was observed in the PP matrix for PP/FG composites containing short glass fiber prepared with all ratios of recycled waste PP/LFG material containing long glass fiber.
