Published: December 2020

Apresentam-se os resultados quantitativos de uma pesquisa de tese que teve como foco o ensino do empreendedorismo mediado por metodologias de Abordagem Colaborativa. Por meio de uma pesquisa-ação, ministrou-se, durante um semestre, tópicos de empreendedorismo em uma turma de 44 alunos da graduação de uma universidade comunitária do Rio Grande do Sul. No primeiro e último dia de aula, os alunos responderam a um questionário denominado de Instrumento de Medida do Conhecimento Empreendedor Básico (IMCEB) a fim de aferir aspectos do saber empreendedor de cada um. Ao término do semestre, comparou-se a média de desempenho do grupo na primeira e segunda aplicação do IMCEB, mediante testes de estatística, a fim de verificar se a diferença observada poderia ser considerada significativa. Evidenciou-se um aumento significativo na média de acertos, e assim, discute-se que uma das hipóteses para explicação desse acontecimento, deriva das práticas de ensino adotadas na disciplina.

Diálogos entre o ensino de história e o uso do português escrito
Authors: Vieira Ana Gabriela da Silva
Published: December 2020

O presente trabalho parte de um estudo de caso de pesquisa-ação desenvolvido em 2017, com uma turma de 6º ano de uma escola de surdos no Rio Grande do Sul. O objetivo foi refletir acerca do o uso de metodologias e práticas pedagógicas para o ensino da disciplina de história em classes de alunos surdos que se encontram no contexto da educação bilíngue, cujas aulas de todas as disciplinas são ministradas em Língua Brasileira de Sinais – Libras – e nas quais o português escrito é estimulado enquanto segunda língua. O entendimento/apropriação desses conceitos nos pareceu ser um dos maiores desafios no que diz respeito ao aprendizado histórico dos sujeitos surdos. Nossa pesquisa, apesar de ter investigado a questão, não ofereceu resposta definitiva para esta problemática, o que nos leva concluir com um questionamento para investigações futuras: quais seriam as possibilidades para o aprendizado de conceitos históricos por turmas de alunos surdos?

Published: December 2020

Abstract. Megalithic Of Gunung Srobu In Melanesian Cultural Context. Megalithic is one of the cultural elements that is discovered worldwide, and it is often used as evidence for cultural hyperdiffusion theory. Such a cultural element is also present in the Melanesian region. However, there is still debate among scholars as to where it comes from and when it was introduced to this area. In this context, the recently excavated megalithic site in Gunung Srobu in Youtefa Bay, Jayapura, Papua may shed light on this matter. This paper is intended to describe the megalithic findings of Gunung Srobu and then compare them with other megalithic findings in several sites in the Melanesian region. The comparative study aims to find out the similarities and differences between Gunung Srobu megalithic and the other Melanesian megalithic as well as to know the position of Gunung Srobu in the Melanesian regional. The method used includes surveys, excavations, and literature studies. The result shows that Gunung Srobu is a very complex megalithic site in the region with very varied shapes and types. The date from around the 4th Century AD put Gunung Srobu as the oldest megalithic site in the region which is likely to occupy a central position in the megalithic distribution in the Melanesian Region.

Abstrak. Megalitik merupakan salah satu unsur budaya yang ditemukan sangat luas di dunia dan sering menjadi bukti bagi teori hiperdifusi. Unsur budaya megalitik juga ditemukan di kawasan Melanesia. Namun, banyak ahli masih memperdebatkan asal-usul dan waktu persebarannya. Dalam konteks ini, temuan megalitik yang baru-baru ini ditemukan dalam penggalian di situs Gunung Srobu, Teluk Youtefa, Papua, mungkin dapat menjelaskan masalah ini. Tulisan ini dimaksudkan untuk mendeskripsikan temuan megalitik di Gunung Srobu dan membandingkannya dengan temuan megalitik di beberapa situs lainnya di kawasan Melanesia. Tujuannya adalah untuk mengetahui persamaan dan perbedaan unsur megalitik antara yang ada di Gunung Srobu dan di situs Melanesia lainnya, serta mengetahui kedudukan megalitik Gunung Srobu di kawasan Melanesia. Metode yang digunakan mencakup survei, ekskavasi, dan studi pustaka. Hasilnya menunjukkan bahwa Gunung Srobu merupakan situs megalitik yang sangat kompleks di kawasan itu dengan bentuk dan jenis yang sangat bervariasi. Pertanggalan yang berasal dari sekitar abad ke-4 M menempatkannya sebagai megalitik tertua yang kemungkinan menempati posisi sentral dalam persebaran megalitik di kawasan Melanesia.

Abstract. The Latest of Archaeological Finds in the Northwest-North of Kerinci Valley, Jambi Highland: A Preliminary Report. Last decade archeological research in Kerinci area, only focused on the south of Kerinci Lake. This region admittedly has archaeological finds richly and has been reported since the colonial era. The report was followed by research working comprehensively in that region eighty years after. The research revealed that archeological finds in the south of Kerinci Lake came from the neolithic to proto-historic era. However, the finds of earthenware fragments accidentally, have discovered the new information about archaeological finds in the north of Kerinci Lake or the northwest-north of Kerinci valley. The purpose of this research is to map the distribution and describing the character of archaeological finds in the northwest-north of Kerinci valley. This research utilizes a descriptive method worked in three stages, videlicet collecting, analyze, and interpreting data. In collecting the data stage collected the primary data and secondary data. In the analyzing stage, utilized qualitative analysis by noticing form, style, and technology attributes. This research revealed that the northwest-north of Kerinci valley area has artifact finds in the form of cord-marked earthenware, red slipped earthenware, and Chinese ceramics. Furthermore, found the carving-stones (petroglyph) too.
 
Abstrak. Penelitian arkeologi dekade terakhir di kawasan Kerinci hanya terfokus pada kawasan di selatan Danau Kerinci. Kawasan ini memang memiliki tinggalan arkeologis yang cukup padat dan telah dilaporkan sejak era kolonial. Laporan tersebut ditindaklanjuti dengan melakukan penelitian yang lebih komprehensif di kawasan tersebut puluhan tahun sesudahnya. Penelitian tersebut mengungkapkan bahwa tinggalan arkeologis di sebelah selatan Danau Kerinci berasal dari masa Neolitik hingga Protosejarah. Namun, temuan artefak tembikar secara tidak sengaja di situs Siulak Tenang pada 2010, telah membuka pengetahuan baru tentang adanya tinggalan arkeologis di bagian utara Danau Kerinci atau bagian barat laut-utara lembah Kerinci. Penelitian ini bertujuan untuk mengetahui sebaran dan mendeskripsikan tinggalan arkeologi di barat laut-utara Lembah Kerinci. Penelitian ini bersifat deskriptif yang dilaksanakan dalam tiga tahap, yaitu pengumpulan data, analisis data dan interpretasi. Pada tahap pengumpulan data, dilakukan pengumpulan data primer dan data sekuder. Pada tahap analisis data digunakan analisis kualitiatif dengan memperhatikan atribut bentuk, gaya, dan teknologi.

NEOLOGISMOS EN EL ÁMBITO TEMÁTICO DEL COLECTIVO LGTB
Authors: Guerrero Ramos Gloria , Pérez Lagos Manuel Fernando
Published: December 2020

En el presente trabajo se realiza un estudio del léxico surgido en torno al movimiento LGTB. Pretendemos demostrar que estamos ante una temática especializada, pero lo suficientemente banalizada como para ser abordada desde diferentes puntos de vista, con una terminología propia y muy nueva, que cambia y se enriquece diariamente. Para ello, seguiremos una metodología basada en la extracción de términos procedentes de textos de distintos niveles de especialidad. Dicha extracción nos permitirá observar en qué medida, gracias a la necesidad de creación de nuevas palabras para designar una nueva realidad social, este colectivo está contribuyendo a enriquecer nuestra lengua. También podremos saber si estamos ante un léxico especializado inaccesible para la gran mayoría de la población, o, por el contario, muy banalizado ya por el interés social que ha supuesto este colectivo en los últimos años. Además, el análisis pormenorizado del léxico recogido contribuirá a definir con claridad si nos encontramos solo ante un movimiento social o si también lo es cultural, ideológico, filosófico, político y económico.
Problems of establishment and development of the Institution of personal data protection in the Russian Federation: historical-legal aspect
Authors: Sekste Yanis Arturovich , Markevich Anna Sergeevna
Published: December 2020

The subject of this research is the problems emerging in the process of establishment and development of the Institution of personal data protection in the Russian Federation. Special attention is turned to the comparison of Soviet and Western models of protection of private life and personal data. The authors used interdisciplinary approach, as comprehensive and coherent understanding of socio-legal institution of personal data protection in the Russian Federation is only possible in inseparable connection with examination of peculiarities of the key historical stages in legal regulation of private life of the citizen. After dissolution of the Soviet political and legal system, the primary task of Russian law consisted in development and legal formalization of the institution of protection of human and civil rights and freedoms, first and foremost by means of restricting invasion of privacy by the state and enjoyment of personal freedom. It is concluded that the peculiarities of development of the new Russian political and legal model significantly impacted the formation of the institution of personal data protection in the Russian Federation. The authors believe that the Russian legislator and competent government branches are not always capable to manage the entire information flow of personal data; therefore, one of the priority tasks in modern Russian society is the permanent analysis and constant monitoring of the development of information technologies.
Impact of the activity of federal executive branches on ensuring national security of Russia in the Arctic Region
Authors: Kuzmenko Artem Olegovich
Published: December 2020

The subject of this research is national interests of the Russian Federation in the Arctic region. Russia's national interests in the Arctic are versatile and quite complex, representing an intersection of the spheres of national interests of Russia as a whole and such particular vectors as the World Ocean, economic sphere, border zone, etc. They are delineated with different degree of specification in a range of normative legal and other documents. Systematization of national interests, factors and threats in the Arctic zone, as well as understanding of their interrelation is an important step in ensuring national security of Russia in the Arctic Region. The analysis of normative legal acts allows systematizing the factors influencing the activity of federal executive branches in the Arctic, as well as outlining the threats to national security of Russia in the Arctic Region. The author analyzes correlation between the factors and threats to Russia's national interests and the vectors of activity of the federal executive branches on their neutralization. Such approach towards interdependence of factors, interests, and vectors of activity is of comprehensive, which discerns it from other existing approaches. The parallel is drawn between the indicated correlation and the dual layer neural network. The author assesses the feasibility of the proposed original approach for estimating the impact of activity of the federal executive branches on ensuring national interests, and offers relevant recommendations.
Bayesian Vector Auto-Regression Method as an Alternative Technique for Forecasting South African Tax Revenue
Authors: Molapo Mojalefa Aubrey , Olaomi John Olutunji , Ama Njoku Ola
Published: December 2020

Tax revenue forecasts are important for tax authorities as they contribute to the budget and strategic planning of any country. For this reason, various tax types need to be forecast for a specific fiscal year, using models that are statistically sound and have a smaller margin of error. This study models and forecasts South Africa’s major tax revenues, i.e. Corporate Income Tax (CIT), Personal Income Tax (PIT), Value-Added Tax (VAT) and Total Tax Revenue (TTR) using the Bayesian Vector Auto-regression (BVAR), Auto-regressive Moving Average (ARIMA), and State Space exponential smoothing (Error, Trend, Seasonal [ETS]) models with quarterly data from 1998 to 2012. The forecasts of the three models based on the Root mean square error (RMSE) were from the out-of-sample period 2012Q2 to 2015Q1. The results show the accuracy of the BVAR method for forecasting major tax revenues. The ETS appears to be a good method for TTR forecasting, as it outperformed the BVAR method. The paper recommends that the BVAR method may be added to existing techniques being used to forecast tax revenues in South Africa, as it gives a minimum forecast error.
Exploring Green Purchasing Behaviour among College Students in a Developing Economy
Authors: Ndofirepi Takawira Munyaradzi , Matema Simbarashe Cowen
Published: December 2020

This study explores the relationships between environmental attitude, green product knowledge, attitude towards purchasing green products, green product purchasing intention, and green purchasing behaviour. Using a cross-sectional survey approach, a random sample of 284 undergraduate students in a Zimbabwean polytechnic completed a self-administered questionnaire. Structural equation modelling (maximum likelihood estimation) was used to analyse the data. The findings indicate that there are positive associations between the following pairs of variables: environmental attitude and attitude towards green purchasing; green product knowledge and green purchasing intention; green product knowledge and green purchasing behaviour; attitude towards green purchasing and green purchasing intention; green purchasing intention and green purchasing behaviour; as well as a non-significant relationship between green product knowledge and attitude towards green. The findings reported that the Theory of Reasoned Action fully supported the students’ intention to buy green products, which then affects their green purchase behaviour. The inclusion of additional constructs to the proposed model was partially supported. The study results highlight the importance of considering product knowledge and other attitudinal factors—specifically environmental attitude and attitude towards green purchasing—when marketing environmentally-friendly products to college-level students.
The impact of changes in audits and penalties on tax compliance behaviour: evidence from South Africa
Authors: Dare Chengetai
Published: December 2020

Tax revenue is a major source of public revenue in South Africa, and it plays an integral role in creating the fiscal space to provide public services and infrastructural development. Tax collection is however impeded by evasion. In its 2014 interim report, the Davis Tax Committee (a tax review committee appointed by the government to inquire into the role of South Africa’s tax system) suggested that South Africa loses a substantial amount of revenue through evasion. To enhance compliance, the government has made several changes to existing tax penalty structures, and introduced new ones as well. The question arises whether these deterrence measures effectively reduce evasion. International empirical evidence on the efficacy of such policies is mixed, and mainly drawn from developed country applications. Hence, evidence from developing countries is limited.

This study employed a laboratory experiment to examine taxpayers’ behavioural responses to changes in audit and penalty rates in South Africa. Results showed that both audits and penalties influenced salaried and non-salaried taxpayers to increase their compliance levels. However, the effect was higher on non-salaried taxpayers. We also found that audit and penalty rates had a negative joint effect on both salaried and non-salaried compliance rates. The impact was larger on salaried taxpayers. These findings suggest that, although audits and penalties are effective enforcement measures, the manner in which they are applied must be given careful consideration.
Perceived Risk, Trust and Familiarity of Online Multi-Sided Pure-Play Platforms Selling Physical Offerings in an Emerging Market
Authors: Carstens Marilise , Ungerer Marius , Human Gert
Published: December 2020

Understanding how customers perceive trust and risk when engaging with online pure-play multi-sided platforms (MSPs), has become critical to the performance of digital marketing strategies. This study explored the relationship between perceived trust, perceived risk and user familiarity associated with MSPs. For the purpose of this study, MSPs are conceptualised as firms that operate only online, that seek to provide transacting services to buyers and sellers, and that sell physical offerings in an emerging market context. Primary data were collected through an online instrument across five MSPs and the study reported the results pertaining to differences and similarities between groups and platforms. The results show that while familiarity drives trust, its impact is moderated by perceived risk. Contrary to common belief, the results show gender differences, but do not confirm age differences in trust and the moderation effect of risk. Moreover, the results also show that the influence of familiarity is not significantly different across MSPs.
Supply Chain Risk Management Strategies: A Study of South African Third-Party Logistics Providers
Authors: Mvubu Mandla , Naude Micheline
Published: December 2020

The purpose of this study was to determine the supply chain risk management (SCRM) strategies that South African third-party logistics (3PL) service providers use to mitigate risks, the extent to which they adopt these strategies and the benefits derived thereof. An exploratory and descriptive method technique was adopted. The empirical study comprised of email surveys administered to 398 supply chain managers employed by South African 3PLs. The findings reveal that respondents place greater importance on risk identification than on the other SCRM strategies. Risk assessment attained the lowest rating, implying that 3PL providers placed the least importance on this risk assessment strategy. Risk response and risk monitoring, reporting and control are all adopted to a significantly lesser extent. The findings also revealed that 3PL providers derive significant benefits from all SCRM strategies. A limitation of this study is that not all 3PL providers affiliated with SAAFF participated. In addition, because only members of senior management were included in the study, the opinions of operational and tactical staff were not obtained. The study contributes to the current body of knowledge on SCRM by exploring how 3PL providers in a developing country, such as South Africa, assess supply chain risks, the strategies they have in place to respond to these risks, and the mechanisms in place to monitor and control SCM risks.
The Broker in Pornography and Violence: Lou Reed in Lulu’s World
Authors:   University of Opole, Kuźnicki Sławomir
Published: December 2020

The article analyses the literary and cultural layers of Lulu, the album published by Lou Reed in collaboration with Metallica, based on Frank Wedekind’s two modernist dramas: Earth Spirit (1895) and Pandora’s Box (1904). In Reed’s reinterpretation, the two plays become his means through which he enters the area of disturbing perversion and graphic pornography. Consequently, Reeds seems to follow Susan Sontag’s diagnosis according to which the goal of pornographic literature is to disorient and to disturb mental balance. In the case of Lulu, it demonstrates Reed’s strategies of crossing the borders between what is commonly accepted and what is rejected because of its non-normative quality. It results in multilayered kinkiness that outreaches the literary frames of the project and makes it possible to view Lulu as a piece of art that is both uncompromising and visionary.
The role of the angiosomaly-oriented endovascular revascularization method in the complex treatment of diabetic foot syndrome
Authors: Petrova V. V. , Smirnov G. A. , Arzhelas M. N.
Published: December 2020

Objective:analyze the effectiveness of the angiosomal oriented endovascular revascularization method in the complex treatment of diabeticfoot syndrome (DFS).Materials and methods.One of the most serious complications of diabetes mellitus is damage to the vessels of the lower extremities. In diabetic macroangiopathy, an extended lesion of medium-sized arteries occurs, which, coupled with an atherosclerotic lesion, often leads to theformation of arterial stenosis and occlusion. The leading method for correcting the patency of the great vessels today is endovascular balloonangioplasty. The study examined the feasibility of selective angiosomal revascularization of the lower extremities. The advantages of angiosomaly-oriented endovascular revascularization are a reduction in the duration of the intervention, a decrease in the volume of the injectedcontrast drug, and targeted restoration of blood flow in the arteries that feed the affected segment of the limb. The study included 49 patientswith a neuroischemic form of DFS with hemodynamically significant stenosis and occlusion of the lower extremities arteries. Patients weredivided into 2 groups. Patients of both groups underwent complex conservative treatment and performed operations on the lower extremities(from surgical debridement to below the knee amputation). Patients of the first group underwent angiosomaly oriented revascularization ofthe lower extremities. Patients from the second group underwent traditional endovascular revascularization.Results.After angiosomaly oriented revascularization, a complete restoration of the initial diameter of the vessel was achieved in 80.0 % ofcases, the absence of residual stenosis – in 82.5 %, the absence of intimal dissection – in 95.0 % of cases. It was possible to achieve laminarblood flow in 90.0 % of cases. A reduction in the revascularization procedure by an average of 30 minutes and a decrease in the consumptionof contrasting pharmaceuticals by an average of 100.0 ml are shown.Conclusion.When evaluating the results of complex treatment of patients after angiosomaly oriented revascularization, a decrease in theaverage hospital stay (11 and 13 days, respectively), a decrease in the average healing time of a wound defect by 1.25 times, a decrease inthe average duration of ulcerative epithelization (9 and 13 days, respectively) and a decrease in the volume of surgical intervention and thenumber of high amputations during the year after angioplasty compared with patients who underwent endovascular revascularization according to the traditional method.
Art, craft and science of limb amputation Part 1. Art and craft of amputation: from Hippocrates to Ambroise Pare (V century B.C. – XVI century)
Authors: Glyantsev S. P.
Published: December 2020

Limb amputation is one of the oldest and most famous operation in surgery. Over the millennia, the tools for its implementation and the technique for its perfomance have been constantly improved. In part 1 of the article, using historical, chronological and dialectical methods, as well as the method of comparative content analysis a number of printed (Hippocrates, V-IV centuries B.C.; Celsus, I century; Abu-alQasim, XI century; A. Paré, XVI century, etc.), material (prostheses, surgical instruments) and visual (engraving, painting, etc.) sources, the circumstances and features of the emergence and development of instruments and techniques for limbs amputation from antiquity to the era were studied and recreated Renaissance. The main indication for amputation was the limb death (gangrene), as well as significant tissue trauma caused by cold or firearms (since the XIV century). The limb was truncated (or isolated) with a circular section along the demarcation line (in ancient times) or within healthy tissues (in the Middle Ages). The operation was carried out under a tourniquet applied above the level of amputation; healthy tissues were shifted proximally; sometimes a second tourniquet was applied - below the cut-off level. Anesthesia was achieved by operating in a state of painful shock, after bloodletting, or by applying a tight ligature (tourniquet). Bleeding was stopped with the surgeon's finger, cauterization or vessel cutting of, ligature of one vessel or the entire bleeding tissue (en masse), suturing of the bleeding vessel (A. Paré), as well as astringents and a bandage. The wound of the stump was left open or brought together with sutures. A major stage in the development of amputation was the work of A. Paré (XVI century), who improved instruments (in particular, clamps for stopping bleeding), the technique of the operation, and pain relief during its performance. If in the Ancient World and in the early Middle Ages amputation was life-threatening, available only to a few of the most skilled doctors, was performed relatively rarely and was akin to art, then after its development in the XIII–XIV centuries. barbers began to perform it everywhere, routinely and gradually turned into a craft. Further development of indications for amputation, techniques for its implementation and the transformation of this operation from a craft into a science from the XVII century. until the middle of the twentieth century will be reflected in part 2 of this article.

Published: December 2020

The development of a method for calculating the use of nozzle hydrodiodes in the design of a twotube hydraulic shock absorber is carried out by considering such problems as the fragility and wear of movable elements (valves) in the design of a hydraulic shock absorber. The paper considers a method of calculation of the shock absorber with hydrododone (the fixed elements). The scientific novelty and task is to replace the movable hydraulic valves in the shock absorber design with nozzle hydraulic diodes, which, theoretically, will extend the service life of this unit, due to the lack of movement dynamics and wear of moving parts

Investigation of deformation of shell with waffle reinforcement during rolling and development of method for compensation of deviations forms
Authors:   Omsk State Technical University, Krivonos E. V.
Published: December 2020

When the waffle panel of AMg6 alloy rolls into the cylindrical shell, a shape defect occurs. Manual elimination of this defect causes local irregularities on butt welded edges of the waffle shell. This leads to difficulties in the process of welding by friction welding with mixing of shells in the section of fuel tanks. It is necessary, on the basis of computer analysis and existing theories, to determine the stresses in the waffle shell that cause internal deformations that result in a general shape error, and to derive patterns under which external influence on the geometry of the mold at the time of bending is possible. The proposed campaign will make it possible to determine auxiliary technological elements for setting standard rolling equipment for defective rolling of wafer shells of missile fuel tanks with various geometric versions of reinforcements. It, in turn, will increase the efficiency of forming shells and the quality of welds when they are welded

Background:

Surgical resection of lesions in the posterior incisural space presents a significant surgical challenge, which may result in postoperative visual complications and other neurological deficits. We, therefore, describe a retractorless interhemispheric transtentorial approach that avoids surrounding brain structures with positive outcomes and no complications or visual damage.

Case Description:

We present four cases of lesions in the posterior incisural space that was treated with a retractorless interhemispheric transtentorial approach. Two patients were previously seen at another institution for a falcotentorial meningioma. We resected the meningiomas with a parietal-occipital interhemispheric transtentorial approach with no neurological deficits. A third patient presented with a large superior vermian hemangioblastoma with a steep angle of the tentorium. The fourth patient had a large upper vermian metastatic lesion with progressive enlargement, which was refractory to radiation treatments and chemotherapy, and we achieved partial resection. Postoperative visual function was completely preserved in all patients.

Conclusion:

A carefully executed retractorless interhemispheric approach in select cases is an effective option to reduce morbidity and prevent visual complications when removing lesions in the posterior tentorial incisure.

Published: December 2020

Background:Acute inflammation of the pancreas, acute pancreatitis (AP) shows an increasing incidence in the world as well as in Algeria. However, lethality and mortality are decreasing, mainly due to recommendations from Atlanta, the International Pancreatology Association and the American Pancreatology Association. The purpose of this work was to analyze the management of AP in the general surgery department of the UHC of Sidi Bel Abbes.

Method: In a retrospective study, 100 acute pancreatitis cases admitted to general surgery between January 2017 and December 2019 were analyzed.

The abdominal scanner was systematic at the admission. The rate of lipasemia, when greater than 3 times the normal one, allowed, in association with the evocative pain, to make the diagnosis. The severity of AP was assessed using the Balthazar score. An MRI was requested when the scanner was inconclusive, to look for an etiology and / or possible complications. 79 (79%) patients received broad-spectrum antibiotic therapy and diet was systematic.

Results: We have transmitted the recommendations of scholar societies to the various specialists and the management of AP is currently more unified and more effective. Scanner is no longer systematic in the early phase. Antibiotic therapy is no longer administered without biological evidence. Enteral nutrition is now possible.

Conclusion: We were able to reach the goal of reducing hospitalization and scanning requests. A further analysis of 100 other PA files is planned to confirm the obtained results.

Structural and morphological control of crystalline nanoparticles is crucial in the field of heterogeneous catalysis and the development of “reaction specific” catalysts. To achieve this, colloidal chemistry methods are combined with ab initio calculations in order to define the reaction parameters, which drive chemical reactions to the desired crystal nucleation and growth path. Key in this procedure is the experimental verification of the predicted crystal facet and its corresponding electronic structure, which in case of nanostructured materials becomes extremely difficult. Here, by employing 31P solid-state nuclear magnetic resonance (ssNMR) aided by advanced density functional theory (DFT) calculations to obtain and assign the Knight shifts, we succeeded in determining the crystal and electronic structure of the terminating surfaces of ultrafine Ni2P nanoparticles at atomic scale resolution. Our work highlights the potential of ssNMR nanocrystallography as a unique tool in the emerging field of facet-engineered nanocatalysts.
Practically Achievable Process Performance Limits for Pressure-Vacuum Swing Adsorption Based Post-Combustion CO2 Capture

Published: December 2020

Practically achievable limits for pressure-vacuum swing adsorption (PVSA)-based post-combustion carbon capture are evaluated. The adsorption isotherms of CO2 and N2 are described by competitive Langmuir isotherms. Two low-energy process cycles are considered and a machine learning surrogate-model is trained with inputs from an experimentally-validated detailed PVSA model. Several case studies are considered to evaluate two critical performance indicators, namely, minimum energy and maximum productivity. For each case study, the genetic algorithm optimizer that is coupled to the machine learning surrogate model, searches tens of thousands of combinations of isotherms and process operating conditions. The framework pairs the optimum material properties with the optimum operating conditions, hence providing the limits of achievable performance. The results indicate that very low pressures ( <~0.2 bar) may be required to achieve process constraints for low feeds with low feed compositions ($<0.15$ mol fraction), indicating that PVSA may not be favourable. At higher CO2 feed compositions, PVSA can be attractive and can be operated at practically achievable vacuum levels. Further, the gap between the energy consumption of available adsorbents and the achievable limits with a hypothetical -best adsorbent varies between 20% to 2.5% as the CO2 feed composition changes between 0.05 to 0.4. This indicates a limited potential for development of new adsorbents of PVSA-based CO2 capture. Future work for PVSA should focus on flue gas streams with high CO2 compositions
Super-Resolution Mapping of a Chemical Reaction Driven by Plasmonic Near-Fields

Published: December 2020

Plasmonic nanoparticles have recently emerged as promising photocatalysts for light-driven chemical conversions. The illumination of these particles results in the generation of highly energetic charge carriers, elevated surface temperatures, and enhanced electromagnetic fields around them. Distinguishing between these often-overlapping processes is of paramount importance for the rational design of future plasmonic photocatalysts. However, the study of chemical reactions mediated by plasmonic effects is typically performed at the ensemble level and, therefore, limited by the intrinsic heterogeneity of the catalyst particles. Here, we report an in-situ single particle study of a chemical reaction driven solely by plasmonic near-fields. Using super-resolution fluorescence microscopy, we achieve single turnover temporal resolution and ~30 nm spatial resolution. This sub-particle accuracy permits the construction of a clear correlation between the simulated electric field distribution around individual metal nanoparticles and their super-resolved catalytic activity maps. Our results can easily be extended to systems with more complex electric field distributions, thereby guiding the design of future advanced photoactive materials.
