Marketing, advertisement and publicity – a study of terms in Brazil
Authors: Filho Miguel Arantes Normanha
Published: February 2021

The main objective of this research consists in contributing with empirical verification of several interpretations done on marketing and advertisement, advertisement and publicity, in a special form used as if they were synonyms. In business context, this can lead companies into financial loss. The research is part of the observation that treats the terms marketing and advertisement as not being the same [semantically], but the concept: advertisement is a specific instrument and marketing is a business philosophy. The wrong interpretation of this terms can induces businessmen [executives] to make strategic mistakes that can influence the cash flow and, consequently, affect the company’s financial economical health.
Social responsibility in the university
Authors: Pereira Raquel Da Silva
Published: February 2021

We believe that universities have a social responsibility, mainly the private ones, considered as enterprises. Thus it is necessary to make a distinction between the social responsibility of the university and the social responsibility in the university, once it would hardly be effective to make this contribution without teaching such concepts to the students. This article intends to moot some questions concerning the social responsibility in the university and the social importance of the professional-citizenship formation, paralleling it with the reflection upon the future professionals, course managers and teachers concerning their inherent responsibilities, in a social context that hardly benefits this practice.
Memorias y justicia a través del océano. Argentina y España frente a sus últimas dictaduras
Authors: Sánchez-Moreno Manuel
Published: February 2021

El artículo propone una revisión de las relaciones formales e informales, institucionales y migratorias entre Argentina y España durante las Juntas Militares y el Franquismo, respectivamente, así como sus procesos de justicia transicional. Las migraciones cíclicas entre ambos países motivadas por cuestiones políticas y económicas han hecho que desde el siglo XIX existiese un interés mutuo que ha unificado unos marcos de pensamiento y cultura común en torno a la memoria comparada.The article proposes a revision of the formal and informal, institutional and migratory relations between Argentina and Spain during the Military Boards and the Franco regime, respectively, as well as their transitional justice processes. Cyclical migrations between the two countries base on political and economic issues have meant that since the nineteenth century there was a mutual interest that has unified some frameworks of thought and common culture around comparative memory.
Memoria histórica e imaginación jurídica: políticas estéticas de la memoria, desde la justicia poética al "forensic turn"
Authors: Winter Ulrich
Published: February 2021

El propósito de este ensayo es indagar en las interrelaciones entre los distintos discursos narrativos de elaboración del pasado dictatorial, particularmente entre los no-fácticos —estético, literario, cultural, etc.— y los fáctico-disciplinarios —el jurídico-legal y el historiográfico—. La hipótesis de este ensayo es que los lenguajes de la historia, del derecho y de la cultura conforman una formación discursiva (Foucault) o interdiscurso de la memoria histórica, esto es, un modelo discursivo de segundo grado, basado en la conjunción de distintos discursos particulares y en base a una serie de analogías e interrelaciones. El ensayo analizará hasta qué punto la judicialización de la política corresponde a un proceso paralelo que podría llamarse judicialización del discurso estético o cultural. Este proceso forma parte del así llamado ‘forensic turn’ o ‘giro forense’. En un sentido amplio, lo forense apunta al hecho de que todos los discursos reivindicativos sobre el pasado constituyen prácticas ‘forenses’, en la medida en que constituyen ‘foros’ de la justicia. Es también en este sentido que puede hablarse de un interdiscurso de la memoria. Se darán algunas pautas para analizar las analogías y transferencias entre discursos fácticos y discursos estéticos. En un primer paso se recuentan algunas interrelaciones entre los tres discursos sobre el pasado. Estas interrelaciones se explican por una serie de analogías intrínsecas o rasgos compartidos, entre otros, su carácter representativo (o epidíctico), narrativo, epistémico, demostrativo y reivindicativo. En contextos de justicia histórica, estas características son inseparables de su función ético-social-restitutiva, retributiva y/o reparadora. En un tercer paso analizaremos algunos axiomas del giro forense, particularmente sus asunciones materialistas y poshumanas y su repercusión en el campo cultural.The paper deals with how factual (historiographical and legal) and nonfactual (aesthetic, literary, cultural, etc.) discourses on the past intertwine. It starts from the hypothesis that the languages of history, law and culture form a discursive formation (Foucault). In the first part, the essay analyzes to which point the judicialization of politics is paralleled by an analogous process of judicialization of cultural and aesthetic discourses. These processes seem to be related to a more general turn in cultural studies, referred to as forensic turn. In the second part, the paper proposes a conceptualization of the interrelations between factual and non-factual narratives of the past. In the third part, the essay discusses some ideological presuppositions of the forensic turn, mainly its materialist and post-human assumptions, as well as its influence on the cultural field.

Published: February 2021

O Brasil viveu em novembro de 2015 o maior desastre ambiental de sua história, o rompimento da barragem de rejeitos de Fundão pertencente à empresa Samarco. Neste contexto, este trabalho busca mapear e quantificar os usos e coberturas da terra e sua relação com os aspectos socioeconômicos oriundos do rompimento da barragem de Fundão em Mariana – Minas Gerais. A área de estudo pretendida será os subdistritos de Bento Rodrigues e Paracatu de Baixo, pertencentes à Mariana que foram devastados pela lama de rejeitos em novembro de 2015. Nos dois distritos cerca 300 famílias perderam, além dos bens materiais, sua identidade, as histórias de vida e de convívio social. As histórias, o patrimônio arquitetônico e cultural foi-se com a lama de rejeitos. Num primeiro momento, fundamentado nos trabalhos e relatórios dos órgãos oficiais, nota-se que os efeitos do rompimento da barragem sobre o ambiente ainda não foram consolidados, pois se trata de fato recente, necessita da conjugação de esforços, do trabalho multidisciplinar de órgãos da sociedade civil e de governo para uma melhor definição desses efeitos. Os mapas de usos retratam a devastação oriunda do rompimento. Os resultados do mapeamento indicam que aproximadamente 496 hectares de floresta densa foram afetados pela lama na área delimitada no estudo. Além disso, 116 ha e 52 ha de vegetação herbáceo-arbustiva e solo exposto, respectivamente, foram suprimidos pelo rompimento. Em relação às classes de uso e cobertura do solo referentes às áreas urbanas, pastagem, reflorestamento e agricultura, foram

Published: February 2021

Received 27 February 2019; accepted 02 September 2019

This paper aims to explore early age strength healing effect of cementitious composite incorporated self-healing microcapsule and curing activity of self-healing microcapsule. Particle characteristic of the microcapsule and micromorphology of cement paste incorporated the microcapsule were characterized by SEM. Curing activity of the microcapsule was analyzed by macroscopic solidification test, DSC and TGA. The influence factors of early age strength healing ratio in cementitious composite incorporated self-healing microcapsule were studied. The results showed that epoxy resin microcapsule had favorable micromorphology. Epoxy resin microcapsule core material had good curing activity and possessed the ability to play the healing role in cementitious composite. Healing temperature and healing age had less impact on the healing effect of the microcapsule in cementitious composite. The microcapsule could be kept good shape in cement paste and combined with cement paste closely. The microcapsule also could rupture and had better dispersion in cement paste. The main fracture behavior of the microcapsule was based on small hole ruptured when cement paste did not occur macro damage. When pre-loading was 0.75 σmax, the particle size of microcapsules was range from 75 μm to 150 μm, proportion of epoxy curing agent was 20 % and proportion of the microcapsule was 6 %, early age strength healing ratio reached the highest of 24.1 %.
Effects of High Carbon Ferrochrome Additions on the Microstructure and Properties of Fe-C-Cr-Nb Hardfacing Alloys
Authors: HUANG Fei , LI Renwei , REN Zhen’an , LIU Wumu
Published: February 2021

Fe-Cr-C-Nb hardfacing alloys composed of 1.07-1.33 wt% C, 0.08-2.61 wt% Cr, and 4.55-4.98 wt% Nb were prepared on C45E4 steel surfaces using alloy steel flux-cored wires. The alloy microstructures were studied by optical microscopy, scanning electron microscopy (SEM), transmission electron microscopy (TEM) and X-ray diffraction (XRD) and the effects of the alloying elements on the hardfacing properties were determined. The results indicate that these alloys contain martensite, austenite and NbC phases. As the C，Cr and Nb mass fraction in the surfacing material increases, the austenite and NbC contents increase, and the martensite content decreases. The NbC crystallite size in the surface layer affects its hardness and thus its wear resistance. The wear resistance first increases and reaches to its maximum value which is 5.7 times higher than that of the C45E4 steel substrate, while by higher increasing of the mentioned elements, it decreases.

Authors: WANG Zhenyu , WANG Jie , CAO Fenghong , MA Yunhai
Published: February 2021

Carbonization treatment contributes to improvement of tribological properties of friction composites. Pure Non-asbestos organic (NAO) friction raw materials were selected, friction composite specimens had been made using a new mixing process and carbonization treatment. Two types of specimens had been prepared to evaluate their performance, one was carbonized a pure non-asbestos organic friction composite specimen and the other was an original brake metal linings of a certain brand of vehicles. Two friction composites were evaluated by brake inertia dynamometer. Their performances were assessed according to the procedure in a European Union Automobile Standards (AK Master). Microscopic photographs of worn surfaces were obtained by scanning electron microscopy to characterize their tribological behavior and wear mechanism. The results showed that pure NAO friction composites had more suitable frictional properties, fade and recovery behavior than the copper-containing metal brake pad, but wear resistance was slightly lower. Carbonation promoted the formation of microporous structure in friction composites, which was helpful to reduce noise and vibration during work.

Authors: DU Weichao , WANG Xiangyun , BI Taifei , LIU Man , ZHANG Jie , CHEN Gang
Published: February 2021

In order to solve wellbore instability problem, a novel clay hydration inhibitor PDWC for water-based drilling fluids was synthesized by copolymerization of tris hydroxyethyl diallyl ammonium bromide (THDAB), sodium allyl sulfonate (AS) and methyl methacrylate (MMA) initiated by redox initiation in an aqueous solution. PDWC was characterized by Fourier transform infrared spectroscopy (FT-IR), Gel Permeation Chromatography (GPC) and Thermo-gravimetry-Differential Scanning Calorimetry (TGA-DSC), respectively. Evaluation of experiments indicated that PDWC showed superior clay hydration inhibition ability compared to some polymer and inorganic inhibitors. Characterization methods included particle size analysis, FT-IR, X-ray diffraction (XRD) and Scanning Electron Microscope (SEM) were utilized to study the inhibition mechanism of PDWC, it was observed that PDWC can be adsorbed on the surface of sodium montmorillonite (Na-MMT) by its hydroxyl functional group, which changed the micro-structure of Na-MMT and made the clay particles increased obviously. However, results of XRD demonstrated that it was difficult for PDWC to enter the inner layer crystal of Na-MMT.

Authors: Hassan Mohamed Tarek , Abubakr Hussein , M. Hussein Mahmoud , S. Salman Gaber
Published: February 2021

At present, simple and classical tuned controllers are widely used in the power system load frequency control (LFC) application. Existing LFC system parameters are usually tuned based on experiences, classical methods, and trial and error approaches, and they are incapable of providing good dynamic performance over a wide range of operating conditions and various load scenarios. Therefore, the novel modeling and control approaches are strongly required, to obtain a new trade-off between efficiency and robustness. Thus, the proposed techniques in this chapter are referred to be an adaptive control technique based on new optimization methods such as Jaya, Practical Swarm Optimization Algorithm, etc., which are used to make an on-line tuning of the LFC parameters in order to face the previous challenges in LFC. The system under study is a small microgrid with a renewable energy source and variable demand load. Digital simulation results are discussed.
Power Flow Management Algorithm for a Remote Microgrid Based on Artificial Intelligence Techniques
Authors: Belmokhtar Karim , Higuita Cano Mauricio
Published: February 2021

This paper presents a novel power flow management algorithm for remote microgrids based on artificial intelligence (AI) algorithms. The objectives of this power management system are enhancing microgrid reliability, improving renewable energy source (RES) integration, and performing active/reactive power control for remote microgrids using the fuzzy logic. This paper evaluates the performance of the proposed algorithm, which consists of both sharing diesel genset active power and regulating reactive power by using stepped and variable profiles of the load, wind speed and solar irradiation. According to the simulation results, better performance is achieved regardless of the rapid variation of different profiles. Thus, both stability and reliability of remote microgrids are demonstrated with the proposed algorithm. Indeed, the active/reactive power control algorithm responds quickly to different events on the remote microgrid, especially to rapid voltage/frequency variations on the AC-link system.

Authors: Karima Zerguine
Published: February 2021

The family of Chironomidae is a group of Diptera insects belonging to the suborder of Nematocera, commonly called “non-biting midges” in the adult stage and “bloodworms” in the larval stage. The Chironomidae are often the most abundant group of macroinvertebrates, in number of species and individuals, encountered in all aquatic environments of freshwater, brackish, terrestrial and even the sea. Likewise, Chironomidae occur in all the continents. The Chironomidae family is divided into 11 sub-families that have diffrent ecological statues. Despite the wealth of data on Chironomidae in the Holarctic region, other parts of the world are poorly studied and few guides to identifying Chironomidae have been produced. This chapter includes a theoretical synthesis on the Chironomidae, it deals with the Biology (life cycle and description of different stages), description of all subfamilies and the ecology of this important family of Diptera.

Authors: Loreta Paun Diana , Mirica Alexandra
Published: February 2021

Pheochromocytomas and paragangliomas are rare neuroendocrine tumors, with genetic background in about 40% of cases, involving more than 30 susceptibility genes. The susceptibility genes can be divided into three main molecular clusters: pseudohypoxic, kinase signaling, and Wnt signaling. Biochemical characterization of these particular tumors should be integrated into the diagnostic algorithm because it can help apply personalized medicine principles and targeted therapy. These tumors can present with very different genotype-phenotype correlations, and their characterization can help the clinical practitioner make optimal clinical management decisions and prioritize genetic testing. This chapter summarizes the most important aspects of genetics and clinical characteristics, together with new genotype-phenotype correlation data.

Basic Theory and Methods of Afforestation
Authors: Duan Jie , Abduwali Dilnur
Published: February 2021

Afforestation is an important practice in silviculture. This chapter outlines the forest site, site preparation, selection of afforestation materials in the process of afforestation. The life cycle of forests is very long, and it is difficult to change them once afforested. Therefore, the forest site must be analyzed in depth before afforestation to maintain the success of afforestation and the healthy growth of forests later. Forest sites are mainly affected by environmental and human activities. To facilitate afforestation, it is necessary to evaluate and classify the forest site factors and achieve a suitable species planted on the right site. Site preparation is also based on site classification. It is usually carried out after determining the type of afforestation land, divided into mechanical land preparation and chemical methods. An essential task of site preparation is to maintain soil moisture and promote seedlings’ survival and growth. Afforestation materials are mainly divided into three categories: seed, seedling, and cutting. The choice of these three types of afforestation materials and methods is related to site conditions, tree species, and age.

Published: February 2021

Apesar de conhecida a importância de produtos alcalinos na degradação de fibras, pouco se conhece sobre os efeitos do calcário durante o processo de compostagem. Diante disso, o objetivo deste trabalho foi avaliar o efeito da adição de diferentes doses de calcário sobre o pH, condutividade elétrica (CE), densidade em base seca, emissões de CO2 e de NH3, teor de N, conteúdos proporcionais (%) de massa e volume e conteúdo (%) de N em relação aos valores iniciais durante a compostagem da mistura de capim-elefante (Pennisetum purpureum Schum.) e torta de mamona (Ricinus communis L.), além da avaliação dos teores de Ca, Mg, P e K ao final do período de incubação . Para tal, foi realizado um experimento em que foram adicionadas diferentes doses de calcário (0; 0,05; 0,5 e 5%, com base na massa do composto), em compostos incubados durante 90 dias. O composto foi elaborado com 67,5% de capim elefante e 32,5% de torta de mamona (massa seca).  O pH dos compostos foi elevado pela adição de calcário, sendo este feito mais evidente aos 90 dias de incubação, onde na maior dosagem foram observados maiores valores de pH. Não foram observadas diferenças nos teores e nas perdas proporcionais de nitrogênio, da massa e do volume inicial dos compostos avaliados ao final do período de incubação. Os teores de cálcio e magnésio foram superiores nos tratamentos em que houve adição de calcário ao final da compostagem, no entanto, os teores de fósforo e potássio não demonstraram diferenças entre os tratamentos. A adição de calcário no processo de compostagem da mistura utilizada desencadeou alterações nas propriedades do composto, sendo os efeitos expressos em maior intensidade pelo tratamento com a maior dose de calcário.

Korean editors’ and researchers’ experiences with preprints and attitudes towards preprint policies
Authors: Yi Hyun Jung , Huh Sun
Published: February 2021

Purpose: This study investigated editors’ and researcher’s experiences with preprints and their attitudes towards preprint policies in Korea.Methods: From December 30, 2019 to January 10, 2020, a Google Forms survey was mailed to members of the Korean Council of Science Editors and the Korean Federation of Science and Technology Societies. The 16 survey items included two demographic items, six items on experience with preprints, five 5-point Likert-scale items on attitudes towards preprints, and three items on advantages and disadvantages.Results: Out of 365 respondents, 56 had deposited their manuscripts on preprint servers, while 49 stated that they allowed preprints in their journals. More than half of the respondents expressed favorable attitudes towards prioritizing preprint deposition, promotion of open access, rapid feedback on preprints, earlier citations, and evidence of research work. Responders in engineering had more experience with the concept of preprints, and were more likely to have heard about preprint servers and preprint deposition by other researchers, than those in medicine. Half of the editors disagreed with the need for preprints, for reasons including a lack of scientific integrity, stealing ideas/scooping data, priority issues regarding research ideas, and copyright problems.Conclusion: The above results showed that preprints are still not actively used in Korea. Although experiences with preprints were not widespread, more than half of the respondents showed favorable attitudes towards preprints. More of a consensus should emerge for preprint policies to be accepted by editors in Korea.

Authors: Choi Ye Jin , Choi Hyung Wook , Kim Soon
Published: February 2021

Purpose: In the current era of the coronavirus disease 2019 pandemic, the trend of sharing new research results through preprint platforms is receiving more attention from researchers than ever before. Preprints have been recognized as a primary and essential method to disseminate new findings faster than traditional publications. Therefore, it has become necessary for journals and editors to acknowledge these changes, prepare preprint policies, and notify authors accordingly. This study aimed to review the status of preprint policies of international publishers and Asian academic society journals.Methods: In total, 383 Asian academic society journals registered in Science Citation Index Expanded were selected as a dataset for analysis between December 11, 2020 and January 8, 2021. Three different parameters were investigated whether each journal had a preprint policy, whether journals allowed preprint manuscripts to be submitted, and whether preprint articles were allowed to be included in the references.Results: Among the 383 Asian academic society journals from 22 countries, only 28 journals accepted preprint manuscripts, and eight allowed the use of preprint manuscripts as references. Japan had the most journals that both had preprint policies and accepted preprint manuscripts, with 13 journals, followed by Korea with 10 journals.Conclusion: Despite the limitations of this study, the results show that editors and journal staff should understand the current preprint trend and try to prepare preprint policies that best meet the journals’ and authors’ interests.

Potential for Development of Novel Food Products from Azanza garckeana Tree Fruit: a Review
Authors: Mwove Johnson Kyalo
Published: February 2021

Azanza garckeana is among the least utilized indigenous wild fruit trees of interest in the arid and semi-arid regions of Africa. The tree's fruit and seeds have found their importance as food while their barks and leaves as medicine because of their vast nutritional and functional components. This paper reviews the utilization of the fruit in food processing demonstrating the potential this species has in the preparation of novel foods. There are few reports on macronutrients and micronutrient composition of the fruit and the seeds, and their utilization in food processing. Some researchers have identified key functional ingredients in the fruits as well as their seeds that could be of benefit when incorporated in the production of value-added food products. This paper not only advocates for the production of value-added food products from this fruit, but also its integration into farming systems to enhance nutritional security and provide ready income for communities in the dry areas in sub Saharan Africa.

Published: February 2021

Rice bran (RB) is a good source of dietary fibre. Addition of rice bran into croissant interferes with the gluten formation of dough and hence affect the physicochemical properties of croissant. The effect of RB addition on physicochemical properties of croissant were determined by using 0%, 10% and 15% RB. Besides, additives such as emulsifiers and enzymes can be used in pastry to enhance the physicochemical properties of croissant. Diacetyl tartaric acid ester of mono-diglycerides (DATEM) and transglutaminase (TGase) were used respectively on 0%, 10% and 15% RB to investigate the effect of such additives on physicochemical properties of croissant. Increased % RB and DATEM, produced a significant decrease in specific volume, together with a significant increase in colour, hardness and chewiness. With increased % RB, TGase caused significant increase in colour, hardness and chewiness but significant decrease in specic volume. The overall moisture sorption isotherm curves of the croissant belong to the Type III isotherm, also known as Flory-Huggins Isotherm (J-shaped). The critical aw obtained from the Guggenheim-Anderson-de Boer (GAB) equation showed that the shelf life of croissants were not positively impacted by the addition of DATEM and TGase and the addition of RB did not cause any significant positive effects on quality characteristics of croissants.

The aim of the present work was to develop a new soy-based food product and evaluate its chemical and sensory properties. A soy-based snack was mixed with rice (Oryza sativa), fortified with eicos-apentaenoic acid (EPA) and docosahexaenoic acid (DHA) Omega-3 fatty acids from sh by-products in encapsulated and emulsion form. Soy beans were subjected to grinding processes, maceration in pure distilled water, filtration and pasteurization, to obtain vegetable drinks and generate solid residue. Finally, a sensory analysis of the product obtained was carried out. The snacks protein content was around 17%. From the sensory evaluation, it could be concluded that the snacks with 50% of okara had great acceptability and the addition of Omega-3 was also acceptable. So, okara represents an excellent raw material that can be utilized for dietary protein fortification. On the other hand, it proposes based on soy and fish by-products allow sustainable development and contribute to the economy of each sector.

An attempt has been made to evaluate antimicrobial, antioxidant and cytotoxicity properties of extracts from onion (Allium cepa L.), garlic (Allium sativum), leaves of guava (Psidium guajava), papaya (Carica papaya), tea (Camellia sinensis), baen (Avicennia alba) and keora (Sonneratia apetala), respectively to apply as natural preservatives for tomatoes. The air-dried plant materials of the respective plant species were subjected to ethanol-methanol extraction, concentrated and stored at 4 °C before use. The extracts were dissolved in 95% ethanol for analysis of antioxidant and antimicrobial properties. Of the extracts tested, tea extracts showed the highest zone of inhibition against several pathogenic bacteria (E. coli 35.0±3.2 mm; P. aeruginosa 29.3±2.6 mm; S. typhi 28.4±2.1 mm and S. pyogenes 27.7±3.7 mm) using the disc diffusion method. In regard to DPPH free radical scavenging assay, keora and guava extracts showed the highest percentage of radical scavenging activity with the values of 89.64± 0.18 and 89.39± 0.88, respectively, which were in agreement with higher total antioxidant capacity (TAC) of these extracts obtained by the phosphomolybdenum method. Brine shrimp lethality bioassay for cytotoxicity assessment showed LC50 of 132.54 ± 18.99 µg/mL for the leaf extract of keora which was found to be most toxic among all studied extracts. The initial results indicated that the extracts could be used for food preservative applications based on the antimicrobial, antioxidant and cytotoxicity properties of the tested extracts. However, efficacy, stability and safety issues need to be addressed with both in vitro and in vivo studies.

In the 2018 International Forum for Teacher Educator Development (InFo-TED) Summer Academy, we, seven teacher educators from Belgium, England, Israel, Norway, and Scotland, became interested in strengthening our ICT competence. At an international conference in June 2019, we presented our personal stories about how we used ICT in our teaching, and what we wanted to learn more about. In June 2020 we wrote a new narrative describing our experiences with ICT which was forced upon us in the spring of 2020. In this narrative, we reflected on how we think our practice will change post-Covid-19. In this paper, we discuss our new narratives in relation to those we wrote in 2019. The two sets of stories were formed into seven vignettes seeking an answer to: 1) How did teacher educators (we) experience the Covid-19 which forced the need for change in working only online, and 2) How do we foresee that the current pandemic will change our future practice? The vignettes show we have had a steep learning curve regarding the technicalities of using ICT, exploring on our own as we were working from home. Moreover, we believe we will not return to pre-Covid-19 ways of teaching as we realise that ICT has not been fully exploited. Yet, we still need to find ways to combine ICT with our pedagogical visions as teacher educators. There are differences, benefits and disadvantages, related to our respective contexts, disciplines and competence. However, we found more similarities than differences. The latter is used to feed into each other’s professional learning. We all had to learn how to manage technical issues, and now we need to find ways to incorporate ICT critically and reflectively to model good teaching in teacher education. Covid-19 was a Black Swan which forced us to change. Now it is time to position ourselves as teacher educators in a changed reality.

Resistance to standard cisplatin‐based chemotherapies leads to worse survival outcomes for patients with esophageal squamous cell carcinoma (ESCC). Therefore, there is an urgent need to understand the aberrant mechanisms driving resistance in ESCC tumors. We hypothesized that ubiquilin‐4 (UBQLN4), a protein that targets ubiquitinated proteins to the proteasome, regulates the expression of Meiotic Recombination 11 Homolog A (MRE11A), a critical component of the MRN complex and DNA damage repair pathways. Initially, immunohistochemistry analysis was conducted in specimens from patients with ESCC (n = 120). In endoscopic core ESCC biopsies taken from 61 patients who underwent neoadjuvant chemotherapy (NAC) (5‐fluorouracil and cisplatin), low MRE11A and high UBQLN4 protein levels were associated with reduced pathological response to NAC (P < 0.001 and P < 0.001, respectively). Multivariable analysis of surgically resected ESCC tissues from 59 patients revealed low MRE11A and high UBLQN4 expression as independent factors that can predict shorter overall survival [P = 0.01, hazard ratio (HR) = 5.11, 95% confidence interval (CI), 1.45–18.03; P = 0.02, HR = 3.74, 95% CI, 1.19–11.76, respectively]. Suppression of MRE11A expression was associated with cisplatin resistance in ESCC cell lines. Additionally, MRE11A was found to be ubiquitinated after cisplatin treatment. We observed an amplification of UBQLN4 gene copy numbers and an increase in UBQLN4 protein levels in ESCC tissues. Binding of UBQLN4 to ubiquitinated‐MRE11A increased MRE11A degradation, thereby regulating MRE11A protein levels following DNA damage and promoting cisplatin resistance. In summary, MRE11A and UBQLN4 protein levels can serve as predictors for NAC response and as prognostic markers in ESCC patients.

Published: February 2021

Early and accurate diagnosis of prostate cancer (PCa) is extremely important, as metastatic PCa remains hard to treat. EWI‐2, a member of the Ig protein subfamily, is known to inhibit PCa cell migration. In this study, we found that EWI‐2 localized on both the cell membrane and exosomes regulates the distribution of miR‐3934‐5p between cells and exosomes. Interestingly, we observed that EWI‐2 is localized not only on the plasma membrane but also on the nuclear envelope (nuclear membrane), where it regulates the nuclear translocation of signaling molecules and miRNA. Collectively, these functions of EWI‐2 found in lipid bilayers appear to regulate PCa cell metastasis through the epidermal growth factor receptor‐mitogen‐activated protein kinase‐extracellular‐signal‐regulated kinase (EGFR‐MAPK‐ERK) pathway. Our research provides new insights into the molecular function of EWI‐2 on PCa metastasis, and highlights EWI‐2 as a potential PCa biomarker.

Published: February 2021

The damping properties of NiTi elements produced through selective laser melting are investigated by tuning the process parameters. To this end, twelve parameters’ sets are selected to fabricate fully‐dense NiTi specimens. Damping is evaluated through loss factor index, mechanical loading cycles (up to 104 cycles), solicitation frequency and strain amplitude. Results confirm that NiTi fabricated through selective laser‐beam melting is an excellent candidate to substitute conventional materials when used in the martensite phase. Furthermore, the selected process parameters enable specific damping performances that can be collected in damping maps which turn out to be practical tools for the fabrication of NiTi parts with tunable damping response.

Quality assurance of the final build part in laser‐powder bed fusion (L‐PBF) is greatly influenced by the various process steps such as powder handling, powder bed spreading, and laser‐material interaction. Each process step is interlinked to each other and can affect the overall behavior of the succeeding steps. Therefore, it is vital to monitor each step individually, post‐process, and establish a link among the data to develop an approach to quantify the defects via inline monitoring. This study focuses on using pre‐ and post‐exposure powder bed image data and in situ melt pool monitoring (MPM) data to monitor the build's overall quality. Two convolutional neural networks have been trained to treat the pre and post‐exposure images with a trained accuracy of 93.16% and 96.20%, respectively. The supervised machine‐learning algorithm called “support vector machine” is used to classify and post‐process the photodiodes data obtained from the MPM. A case study on “benchmark part” is presented to check the proposed algorithms' overall working and detect abnormalities at three different process steps (pre and post‐exposure, MPM) individually. This study shows the potential of machine learning approaches to improve the overall reliability of the (L‐PBF) process by inter‐linking the different process steps.
Biaxial Inflation Stretch Test for Flexible Electronics

Published: February 2021

Printed flexible ink manufacturers typically report electrical performance under uniaxial strains. Under observed real‐world conditions, flexible ink systems experience strain in multiple dimensions. This indicates a potential for misrepresentation of the failure modes of these materials in application if strictly characterized using uniaxial methods. A novel test method is proposed in which a device is clamped around its periphery and subjected to an inflation pressure to induce a biaxial strain‐state. The electrical performance of the ink is monitored via in situ resistance measurement. 3D digital image correlation and finite‐element analysis are used to validate the calculated stress–strain state. Comprehensive analytical and numerical models are developed and compared with experimental results. The following findings are reported: 1) a commercial silver‐based stretchable ink screen‐printed onto a thermoplastic polyurethane substrate can withstand upward of 70% uniaxial strain without electrical failure, yet experiences a loss of conductivity at just 12% biaxial strain, 2) the proposed inflation test setup successfully creates a biaxial strain‐state in the substrate–ink system while measuring the system's electrical performance, and 3) models, based on 3D percolation theory and the mechanics of pressurized membranes, accurately describe the electrical and mechanical behavior of the substrate–ink system.
