The Europeana Collections – Transylvanian Prints from the Collections of the National Museum of the Union from Alba Iulia
Authors: Negoi Ana Maria Roman
Published: March 2020

The Europeana Collections, inaugurated in 2008, represents the completion of an ambitious project intended to be a journey and an instrument for the access to the culture, the history and the identity of the Europeans. Nowadays, Europeana contains in its collections more than 58 million digital units, organized on domains and themes, from art works, artefacts and books to movies and music. The patrimony of the Europeana enriches yearly and constantly by the contribution of the European Member States, as response to the common aspiration to open the access to knowledge beyond the national or territorial borders. The Europeana Project represents the implementation by digitization of a set of standards and of a unitary approach on the valorisation by digitization of the patrimony of the European states. The country reports reflect the most accurate the measures and the achievements of each contributing state to Europeana. Therefore, the Romanian report – a document updated in January 2019 – presents punctually the achievements of our country and of the Romanian institutions contributing to the enrichment of the Europeana collections. The list of the contributors contains, next to the names of well-known libraries, the name of the National Museum of the Union from Alba Iulia, with 986 digital units. Related to the field of the prints, the National Museum of the Union is not a direct contributor, but its collections are uploaded by other contributors. The National Museum of the Union has a remarkable and extremely valuable collection of Transylvanian books, mainly printed in Cluj during the 18th century. There are 78 titles with a preponderantly religious, juridical and educational content, representing an important segment of the national cultural heritage. The present paper aims to approach the above mentioned works and to identify them in the Europeana collections.
Optical characterization of thin Al2O3 layers deposited by magnetron sputtering technique at industrial conditions for applications in glazing
Authors: Dywel Piotr , Skowroński Łukasz
Published: March 2020

In this study, thin Al2O3 films (11 nm – 82 nm) were deposited by means of a recently developed pulse gas injection magnetron sputtering method and investigated by means of atomic force microscopy, spectroscopic ellipsometry and spectrophotometry. Quite low values of optical constants (1.581 to 1.648 at λ = 550 nm) of the alumina films are directly associated with specific growth conditions (pulse injection of the reactive or reactive + inert gas) in the pulse gas injection magnetron sputtering process. The light transmittance of Al2O3/glass systems (86 % to 90 %) is only a few percent lower than that calculated for glass (93 %).

Published: March 2020

As implied in the title, the triple-layer remote phosphor (TRP), constructed with the yellow YAG:Ce3+ layer at the bottom, the red CaMgSi2O6:Eu2+,Mn2+ phosphor layer on the top, and the green Ba2Li2Si2O7:Sn2+,Mn2+ phosphor layer between these two layers, is suggested in this paper to improve the color and luminescence of white LEDs (WLEDs). In order to control the red light for the purpose of increasing the color rendering index (CRI), it is suggested that the red CaMgSi2O6:Eu2+,Mn2+ phosphor should be applied in the TRP structure. Simultaneously, the structure uses the green Ba2Li2Si2O7:Sn2+,Mn2+ phosphor layer to control the green light, which increases the luminous efficacy (LE) of WLEDs. In addition, when the concentration of these two phosphors increases, the yellow YAG:Ce3+ concentration must be reduced to keep the average correlated color temperatures (ACCTs) stable at 6000 K to 8500 K. Besides, appropriate adjusting of CRI, LE, and color quality scale (CQS) is also analyzed by modifying the concentration of the green phosphor and red phosphor. The results show that the CRI can get better values if CaMgSi2O6:Eu2+,Mn2+ concentration is higher. In contrast, the CRI decreases dramatically when the concentration of Ba2Li2Si2O7:Sn2+,Mn2+ increases. Meanwhile, CQS can be significantly increased in the range of 10 % to 14 % CaMgSi2O6:Eu2+,Mn2+, regardless of the concentration of Ba2Li2Si2O7:Sn2+,Mn2+. In particular, along with the improvement of CRI and CQS, LE can also be increased by more than 40 % by reducing the scattered light and adding the green light. Obtained results are a valuable reference for manufacturers for improving WLEDs color and luminescence quality to produce a broader range of WLEDs with better quality fulfilling social needs.
Mechanical recanalization for acute bilateral cerebral artery occlusion – literature overview with a case
Authors: Jeromel Miran , Milosevic Zoran V , Oblak Janja Pretnar
Published: March 2020

Background

Acute bilateral internal carotid artery (ICA) and/or middle cerebral artery (MCA) occlusion is extremely rare and associated with poor clinical outcomes. There are only a few reports in the literature about mechanical thrombectomy being performed for acute bilateral occlusions. The treatment strategies and prognoses (clinical outcomes) are therefore unclear.

Methods

A systematic review of the literature was performed through several electronic databases with the following search terms: acute bilateral stroke, mechanical recanalization and thrombectomy.

Results

In the literature, we identified five reports of six patients with bilateral ICA and/or MCA occlusion treated with mechanical recanalization. Additionally, we report our experience with a subsequent contralateral large brain artery occlusion during intravenous thrombolytic therapy, where the outcome after mechanical thrombectomy was not dependent on the time from stroke onset but rather on the capacity of collateral circulation exclusively.

Conclusions

Acute bilateral cerebral (ICA and/or MCA) occlusion leads to sudden severe neurological deficits (comas) with unpredicted prognoses, even when mechanical recanalization is available. As the collateral capacity seems to be more important than the absolute time to flow restoration in determining the outcomes, simultaneous thrombectomy by itself probably does not lead to improved functional outcomes.
The Cognitive Motivation Behind the Semantics of Hungarian Co-Verbial Constructions with Össze and Szét
Authors: Grygiel Marcin
Published: March 2020

The use of an elaborate system of co-verbial constructions is the hallmark of the Hungarian language and one of the biggest challenges a translator or a learner of this language has to face. Co-verbial constructions consist of verbs, or their derivates, accompanied by a limited number of prefixes or particles that modify their meanings. They not only perform numerous syntactic and lexical functions, which is important in terms of language production, but also are able to change the meaning of the verb completely. The aim of this study is to trace the cognitive motivation behind the use of Hungarian co-verbial constructions with össze/szét and to show that the meanings developed by these constructions can be organized with reference to prototypical scenes structured in the form of a radial category.
“That’s the Metaphor You’re Going for?” Deliberate Metaphor and Humor
Authors: Wawrzyniuk Justyna
Published: March 2020

This paper aims at discussing the function of deliberate metaphors in humorous narratives due to the similarities in mechanisms underlying both elements of language. This corpus-based analysis has shown the relation between deliberate metaphors and elements of the knowledge resources of the General Theory of Verbal Humor (GTVH). The study has revealed that if deliberate metaphors are part of humorous narratives, they are more likely to be the source of the funniness rather than the transit system which conveys the metaphors themselves. With this in mind, it is possible to assess the extent to which deliberate metaphors contribute to humor.
INOVAÇÃO SOCIAL NA ANÁLISE DO CICLO DE EXPANSÃO DO PROGRAMA 1 MILHÃO DE CISTERNAS
Authors: De Medeiros Carolina Beltrão , Gómez Carla Regina Pasa
Published: March 2020

Este artigo tem como objetivo apresentar uma análise da expansão de uma inovação social, o Programa Um Milhão de Cisternas (P1MC). A gestão do programa foi iniciada pela mobilização de um grupo pequeno de atores sociais, a partir da implantação de uma tecnologia social. O programa foi ampliado por meio de uma rede de atores organizacionais até ser institucionalizada pela Lei 12.873, de 24 de outubro de 2013, que instituiu o Programa Cisternas. A natureza do estudo é qualitativa e, para a análise dos dados coletados, foi utilizado como referencial o Modelo Teórico da Expansão de Iniciativas de Inovação Social (Medeiros, 2018) e análise de conteúdo categorial. A discussão dos dados possibilitou inferir que há uma expressiva participação dos atores organizacionais na expansão, que possibilitam melhorias na execução do programa nos territórios, concedendo este retorno como aprendizado para os atores institucionais, que também colaboram no processo de coordenação de atividades. Como conclusão, corrobora-se que o P1MC segue um percurso de expansão por meio de abordagens de gestão tanto top-down quanto bottom-up, validando-as para esta iniciativa de inovação social e ressaltando o papel fundamental exercido pelos atores organizacionais no processo. Como aprimoramento metodológico, sugere-se que o Modelo teórico da Expansão de Iniciativas de IS (Medeiros, 2018) seja aplicado em outros casos para que se possa validar, de forma mais específica, a categoria Mobilização de Atores, que está apresentada, de forma bastante genérica, e não apontou os diversos papéis que os atores assumiram durante o percurso de expansão do P1MC.

Published: March 2020

objetivo deste estudo é analisar a viabilidade de utilização de um contratofuturo referenciado em suínos, no Brasil. O interesse decorre da importância da cadeiade suínos neste país, que, apesar de relevante, apresenta grande instabilidade, principalmentequando se avaliam os riscos de preços do produto. No entanto, a introdução deum novo contrato não é uma questão simples, visto que muitos contratos são lançadosno mercado, mas tempos depois fracassam. Assim, o estudo do mercado e das característicasda commodity deve ser realizado antes da inovação contratual, para que ospontos positivos e possíveis pontos problemáticos sejam identificados. O modeloutilizado foi desenvolvido por Pennings e Leuthold (1999), que avaliaram as característicasmicro e macro da tomada de decisão de uma inovação contratual. Avaliaram-se,principalmente, as características macro, sendo estudadas as variáveis: i) perecibilidadee possibilidade de a commodity ser estocada; ii) homogeneidade e capacidade demensuração; iii) volatilidade de preço; iv) tamanho do mercado físico; v) grau decompetição do mercado; vi) contratos à termo; e vii) competição com outros contratos.Os resultados permitem concluir, por um lado, que as variáveis ii), iv), v) e vi) podemser os principais entraves a implantação de um contrato futuro referenciado em suínosvivos, no Brasil.

Behavioural economists study the effects of social, cognitive, emotional and economic factors on individuals and institutions decisions, and their consequences. Libertarian paternalism argues that private and public sector entities should guide people's choices in directions that will improve their quality of life. Based on the knowledge of how people make decisions and their biases, strategies can be designed to take the healthiest choices. In the prevention of obesity, some interventions based on behavioural economics have proven efficatious. However, multifaceted interventions and, above all, regulatory measures remain the most effective.
Offshoring of Services in Spain: International Fragmentation of Activities or Change in Procurement Sources?
Authors: Fuster García Begoña , Martínez Mora Carmen
Published: March 2020

This paper studies the offshoring of services and whether this phenomenon is linked to the international fragmentation of activities or to a shift in outsourcing to foreign rather than domestic suppliers. Analysis is performed using the National Accounting input-output tables of Spain’s National Institute for Statistics for the 2000-2007 period. The major findings reveal growth in the offshoring of intermediate services to foreign countries by service providers and manufacturing companies, with greater prevalence among the former. In manufacturing sectors, the analysis indicates that domestic suppliers are being replaced by their foreign counterparts. However, in service sectors these processes correspond mainly to the international fragmentation of activities.

The real estate industry in Indonesia is forecasted to keep growing in the future. There will be significant opportunities in the capital market for investment. It is essential for investors who will invest in this industry to understand what factors are essential to predict stocks price movement, especially for stock trading investors. For companies in the industry, knowing what they should do to attain growth more significant than the industry itself is essential to attract investors. The research purposes are to study the correlation between selected financial components and stock price. The analysis was done by calculating the correlation between financial components with stock price using 10-years period data.

The results show there are six classes of companies according to correlation analysis: significant with EBIT, significant with dividend, significant with RE, significant with DER, multi significant, and insignificant. The most substantial component is the debt to equity ratio. Recommendation for investors is to understand the industry and aware of companies' activities before investing. Investing in sustainable companies leads to stable capital gain while for risk-taker investors, investing in other companies should be based on the projects handled by the company. For companies, they should have focused on the factors that correlate with their stock price.

Determination of annealing temperature of the primer is the first step for genetic diversity analysis using molecular markers such as RAPD (Random Amplified Polymorphic DNA). This study aims to determine annealing temperature (Ta) of RAPD primers on Kampar Mungbean. Methods included total DNA extraction, electrophoresis, and annealing temperature optimization of four RAPD markers namely OPD-20, OPI-06, OPI-13, dan OPX-13. Optimization was conducted by reducing the Tm value (Time melting) of each primer with 3 (Tm-3) and 5 (Tm-5). The results showed that the optimization using OPD-20 and OPX-13 produced bands at Tm-3 and Tm-5. Meanwhile, optimization using OPI-06 and OPI-13 resulted in bands at Tm-3. The next step was to choose the exact Ta based on the clear and bright band. In conclusion, exact Ta for OPD-20, OPI-06, OPI-13, and OPX-13 were 36,1°C, 38,1°C, 35,4°C, and 32,5°C respectively.

ABSTRAK

 

Indragiri Hilir is a district in Riau Province where around 70% of the population depends on coconut plantations. In 2018, a large population explosion of coconut beetles, Oryctes rhinoceros was reported in several regions in the Province. The population explosion that occurred in Sungai Nyiur Village, Tanah Merah Subdistrict, has caused conflicts between the community who own coconut plantations and oil palm plantation companies in the area related to the source of pest outbreaks. The regional government has formed an independent team to conduct scientific studies to examine this problem. The independent team in charge consisted of 12 personnel involving universities (UIR) and Riau BPTP agricultural institutions. The steps taken include surveys, interviews, field investigation, and trapping. The survey was conducted to determine the epicenter of the attack by evaluating the intensity of the damage visually and with the drone aid. Excavation and inspection of breeding sites were carried out to evaluate the presence and presence of beetles and larvae. Pheromone trap installation is intended to analyze the distribution of coconut beetles. Interviews were carried out both for coconut farmers and staff of oil palm plantation companies related to the chronology of beetle pest explosion and activities carried out on oil palm plantation companies.  The findings obtained from the study conducted were presented to both parties in dispute and also the Regional Government of Indragiri Hilir as described in this paper.

Superionic Lithium Intercalation through 2 nm x 2 nm Columns in the Crystallographic Shear Phase Nb18W8O69
Authors: Griffith Kent , Grey Clare P.
Published: March 2020

Nb18W8O69 (9Nb2O5×8WO3) is the tungsten-rich end-member of the Wadsley–Roth crystallographic shear (cs) structures within the Nb2O5–WO3 series. It has the largest block size of any known, stable Wadsley–Roth phase, comprising 5 x 5 units of corner-shared MO6 octahedra between the shear planes, giving rise to 2 nm x 2 nm blocks. Rapid lithium intercalation is observed in this new candidate battery material and 7Li pulsed field gradient nuclear magnetic resonance spectroscopy – measured in a battery electrode for the first time at room temperature – reveals superionic lithium conductivity with Li diffusivities at 298 K predominantly between 10–10 and 10–12 m2·s–1. In addition to its promising rate capability, Nb18W8O69 adds a piece to the larger picture of our understanding of high-performance Wadsley–Roth complex metal oxides.
Sunlight-driven photocatalytic hydrogen production from water using metal-doped strontium titanate perovskite
Authors: Sharma Pushkal , Lee Cheng-Ting , Wu Jeffrey Chi-Sheng
Published: March 2020

The effects of various metal dopants on the photocatalytic water splitting activity of SrTiO3 -based photocatalysts were investigated using experimental studies. The SrTiO3:Rh (1%) has been found to give the best efficiency in water splitting out of the various metal-doped samples studied. However, the same host doped with other metal dopants such as Fe, V, Ga, and Sb leads to negligible hydrogen evolution even when at least Fe has a better visible light response. Our results accompanied by previously conducted theoretical studies by our group explain the high photocatalytic water splitting activity of Rh doped SrTiO3 . Furthermore, the effects of the amount of catalyst, the proportion of sacrificial agent and pH were studied for the SrTiO3:Rh (1 mol%) along with studying its activity with seawater.
In Silico Exploration of Molecular Mechanism and Potency Ranking of Clinically Oriented Drugs for Inhibiting SARS-CoV-2’s Main Protease
Authors: Huynh Tien , wang haoran , Luan Binquan
Published: March 2020

Currently, the new coronavirus disease 2019 (COVID-19) is a global pandemic without any well calibrated treatment. To inactivate the SARS-CoV-2 virus that causes COVID-19, the main protease (Mpro) that performs key biological functions in the virus has been the focus of extensive studies. With the fast-response experimental efforts, the crystal structures of Mpro of the SARS-CoV-2 virus have just become available recently. Herein, we theoretically investigated the binding mechanism between the Mpro's pocket and various marketed drug molecules being tested in clinics to fight COVID-19 that show promising outcomes. Combining all existing experiment results with our computational ones, we revealed an important ligand-binding mechanism for the Mpro that the binding stability of a ligand inside the Mpro pocket can be significantly improved if the partial ligand occupies the so-called "anchor" site of the Mpro. Along with the high-potent drugs/molecules (such as nelfinavir and curcumin) revealed in this study, the newly discovered binding mechanism paves the way for further optimizations and designs of Mpro's inhibitors with a high binding affinity.
Machine Learned Prediction of Reaction Template Applicability for Data-Driven Retrosynthetic Predictions of Energetic Materials

Published: March 2020

State of the art computer-aided synthesis planning models are naturally biased toward commonly reported chemical reactions, thus reducing the usefulness of those models for the unusual chemistry relevant to shock physics. To address this problem, a neural network was trained to recognize reaction template applicability for small organic molecules to supplement the rare reaction examples of relevance to energetic materials. The training data for the neural network was generated by brute force determination of template subgraph matching for product molecules from a database of reactions in U.S. patent literature. This data generation strategy successfully augmented the information about template applicability for rare reaction mechanisms in the reaction database. The increased ability to recognize rare reaction templates was demonstrated for reaction templates of interest for energetic material synthesis such as heterocycle ring formation.

Authors: Fier Patrick , Kim Suhong , Cohen Ryan
Published: March 2020

We report the development of a multifunctional reagent for the direct conversion of pyridines to Boc-protected 2-aminopyridines with exquisite site- and chemoselectivity. The novel reagent was prepared on 200 gram-scale in a single step, reacts in the title reaction under mild conditions without precautions towards air or moisture, and is tolerant of nearly all common functionality. Experimental and in-situ spectroscopic monitoring techniques provide detailed insights and unexpected findings for the unique reaction mechanism.
Green-to-Blue Triplet Fusion Upconversion Sensitized by Anisotropic CdSe Nanoplatelets
Authors: VanOrman Zachary A. , Bieber Alexander S. , Wieghold Sarah , Nienhaus Lea
Published: March 2020

Green-to-blue photon upconversion bears great potential in photocatalytic applications. However, current hybrid inorganic-organic upconversion schemes utilizing spherical CdSe nanocrystals are often limited by energetic polydispersity, low quantum yields and an additional tunneling barrier resulting from the necessity of surface-passivating inorganic shells. In this contribution, we introduce anisotropic CdSe nanoplatelets as triplet sensitizers. Here, quantum confinement occurs in only one direction, erasing effects stemming from energetic polydispersity. We investigate the triplet energy transfer from the CdSe nanoplatelets to the surface-bound triplet acceptor 9-anthracene carboxylic acid. We further focus on the influence of nanoplatelet stacking and singlet back transfer on the observed upconversion efficiency. We obtain an upconversion quantum yield of 5.4% at a power density of 11 W/cm2­ using the annihilator 9,10-diphenylanthracene, and a low efficiency threshold Ith of 237 mW/cm2.

Introducción realizada por el director honorífico de la revista, Antonio Altarriba.

Y llegó el tiempo de jugar con las palabras... Un poco después de empezar a jugar con las libertades, los derechos, las urnas y otras diversiones democráticas, hizo acto de presencia el desparrame verbal. Al menos así fue para mí. Siempre había sido sensible a las palabras, a su sonoridad rotunda, cavernosa, arisca, insinuante y, con frecuencia, significativamente confusa.
Parked Car Interior Temperature Investigation in Brunei Darussalam
Authors: Rakib Uddin Mohammad , Haji Ya’akub Muhammad Faiz
Published: March 2020

When a car is parked under the sunlight for a long period of time, solar radiation enters the vehicle through the car glass and becomes trapped inside the car. This causes the cabin interior air temperature to increase and this is especially noticeable in tropical countries with hot and humid climates that are situated near the equator like Brunei Darussalam. Aside from causing thermal discomfort to the passengers inside the car, degradation of the surfaces of the car interior may also be accelerated. This paper aims to demonstrate the severity of the heat by recording a number of temperature measurements in a certain period of time for two different types of cars, under three different conditions for each car and comparing them to the ambient temperature. It is observed that the interior temperature depends on the design of the car. We experimented temperature measurements for two types of car models, i.e., saloon and SUV models. Saloon car is design such as way that its interior volumes space is smaller than the SUV designed car. The smaller interior volume spaced Saloon car exhibits higher maximum temperature of 68.7°C whereas the larger interior volume spaced SUV car exhibits maximum temperature of 59.4°C under fully exposed to sun with same environmental conditions.
Conquista feudal y transformaciones agrarias: colonización agrícola y ganadería en el prado de Tortosa, siglos XII-XIII
Authors: Virgili Antoni
Published: March 2020

This paper examines the earliest colonisation of the Tortosa plain, following the Christian conquest of 1148. The research follows a historiographicline that highlights the impact of the conquest of al-Andalus by Christian kingdoms from the north of the Iberian Peninsula. It focuses especially on the modifications that the conquerors made to the Andalusian agrarian landscape, aimed chiefly at increasing production and feudal rents. The research methodology involved examining the documentation generated by the conquest, then comparing and contrasting it to archaeological sur vey work, field work and study of available maps. Agrarian spaces are identified and landscape features descr ibed, including networks of drainage canals, roads, a flour mill, caves, estates (mansi) and large meadows dotted with ponds and lagoons. The conquerors expanded the drainage infrastr ucture and divided the land into homogenous, but not necessarily contiguous, field systems with vineyards, green gardens, and plots for dryland agriculture. However, large areas remained uncultivated for grazing.
