Las Bacterias Acido Lácticas (BAL) se destacan por su capacidad de producir sustancias de actividadantimicrobiana como ácidos orgánicos, peróxido de hidrógeno y bacteriocinas, es por esta razón que se realizó una búsqueda, aislamiento e identificación de cepas BAL provenientes de yogurt y queso hilado de producción artesanal y en producción comercial en la región del Huila en Colombia, una vez aisladas se evaluó la actividad antimicrobiana frente a cepas de patógenos de Escherichia coli (aislada del restaurante de la Universidad Surcolombiana y de una venta ambulante de ají en tres diferentes métodos: presencia de células (método de discos), ausencia de células (método de pocillos) con pH ácido y neutro. Los resultados obtenidos en la actividad antimicrobiana por parte de las BAL, abre la posibilidad de ofrecer a la industria de lácteos local semi-industrial, artesanal y a los consumidores, información que les ayude a la producción de alimentos (Yogurt y Quesillo) con atributos de calidad, y potencial probiótico con actividad antimicrobiana, posicionándolos como un alimento funcional. Los resultados de la caracterización físico química de los productos lácteos (Yogurt y Quesillo), elaborados y distribuidos de manera artesanal y semi-industrial en el departamento del Huila, son de gran relevancia no solo para garantizar su calidad y aceptabilidad en el mercado para los consumidores; sino también como una herramienta de identidad útil para clasificar los diversos tipos de quesillos y yogurts.
Vom jüdischen Sabbat zum islamischen Freitag. Eine religioswissenschaftliche Auslegung der 62. Sure des Koran
Authors: Schmitz Bertram
Published: August 2019

Historisch gesehen ist der Koran in enger Beziehung zum Judentum und Christentum, spezifisch gesehen in deren historischer Gestalt des 7. Jahrhunderts im Nahen Osten entstanden. Viele Suren beziehen sich explizit auf biblische Texte und auf Rituale aus diesen beiden Religionen. Dies trifft auch für den Freitag als „Tag der Versammlung“ zu. In der 62. Sure wird seine Beziehung zum Sabbat deutlich. Je genauer die Übersetzung und je wörtlicher die Formulierungen verstanden werden, desto klarer wird diese Verbindung. Sie geht sogar so weit, dass der (sekundäre) Titel dieser Sure durchaus als „Synagoge“ im wörtlichen Sinn verstanden werden kann. Im weiteren Verlauf wurde die Sure so interpretiert, dass sie als Grundlage für den klassischen islamischen „Freitag“ verwendet werden kann. Der vorliegende Beitrag zeigt diese Transformation auf.
Ética da Dádiva
Authors: Bayer Oswald , Wiese Werner
Published: August 2019

In this article, there is a critical dialogue with the philosophy of modernity, especially with the Kantian tradition of the categorical imperative, on the subject of ethics. At first, an approach to the theme of ethics is made from the philosophy of religion, defending an understanding of ethics as a categorical gift. As a counterpoint to Kant, it is argued that the pre-ethical and aesthetic dimensions precede the ethical dimension. What is ethical is understood within the concepts of receiving and transmitting forward, inspired in 1 Cor 15.3. It is understood that ethics covers an asymmetry between what the person receives and what he gives of himself. In a second moment, one begins with the theological explanation of ethics, developing themes such as “reality of creation as a gift”, “deliver and receive the holy supper”, “Christ as gift”, “the verb: the process of giving” “Gift and promise”. In a third moment the concept of gift ethics is widely developed. The article represents a contribution to the theological foundation of ethics, based on a critical dialogue with the philosophy and philosophy of religion.

Published: August 2019

The surface structure and composition of functional materials are well known to be critically important factors controlling the surface reactivity. However, when doped the surface composition will change and the challenge is to identify its impact on important surface processes and nanoparticle morphologies. We have begun to address this by using a combination of density functional theory and potential-based methods to investigate the effect of surface dopants on water adsorption and morphology of the technologically important material, CeO2, which finds application as electrolyte in SOFCs, catalyst in soot combustion, and enzyme mimetic agent in biomedicine. We show that by mapping CeO2 surface phase diagrams we can predict nanoparticle morphologies as a function of dopant, temperature and water partial pressure. Our results show that a low temperature, un-doped CeO2 nanocubes with active {100} surface sites are thermodynamically stable. But at the typical high temperature operating conditions favors polyhedra where {100} surfaces are replaced by less active {111} surfaces by surface ion migration. However, on doping with trivalent cations, such as Gd3+, will increase binding of water on the {100} surfaces and hence act to preserve the cuboidal architecture, by capping the active surfaces. As surfaces tend to be decorated by impurities and dopants it is clear that their role should receive more attention and the approach we describe can be routinely applied to nanomaterials, morphologies and associated active/inactive surfaces.
Sterically Controlled Late-Stage C–H Alkynylation of Arenes
Authors: Mondal Arup , Chen Hao , Flämig Lea , Wedi Philipp , van Gemmeren Manuel
Published: August 2019

Phenylacetylenes are key structural motifs in organic chemistry, which find widespread applications in bioactive molecules, synthetic intermediates, functional materials and reagents. These molecules are typically prepared from pre-functionalized starting materials, e.g. using the Sonogashira coupling, or using directing group-based C–H activation strategies. While highly efficient, these approaches remain limited by their inherent selectivities for specific regioisomers. Herein we present a complementary approach based on an arene-limited nondirected C–H activation. The reaction is predominantly controlled by steric rather than electronic factors and thereby gives access to a complementary product spectrum with respect to traditional methods. A broad scope as well as the suitability of this protocol for late-stage functionalization are demonstrated.
Learning from the Density to Correct Total Energy and Forces in First Principle Simulations
Authors: Dick Sebastian , Fernandez-Serra Marivi
Published: August 2019

We propose a new molecular simulation framework that combines the transferability, robustness and chemical flexibility of an ab initio method with the accuracy and efficiency of a machine learned force field. The key to achieve this mix is to use a standard density functional theory (DFT) simulation as a pre-processor for the atomic and molecular information, obtaining a good quality electronic density. General, symmetry preserving, atom-centered electronic descriptors are then built from this density to train a neural network to correct the baseline DFT energies and forces. These electronic descriptors encode much more information than local atomic environments, allowing a simple neural network to reach the accuracy required for the problem of study at a negligible cost. The balance between accuracy and efficiency is determined by the baseline simulation. This is shown in results where high level quantum chemical accuracy is obtained for simulations of liquid water at standard DFT cost, or where high level DFT-accuracy is achieved in simulations with a low-level baseline DFT calculation, at a significantly reduced cost.
A Commercially Available Ruthenium Compound for Catalytic Hydrophosphination
Authors: Cibuzar Michael P. , Dannenberg Steven G. , Waterman Rory
Published: August 2019

Hydrophosphination with a commercially available ruthenium compound, bis(cyclopentadienylruthenium dicarbonyl) dimer ([CpRu(CO)2]2), was explored. Styrene derivatives or Michael acceptors react readily with either primary or secondary phosphines in the presence of 0.1 mol% of [CpRu(CO)2]2 under photolysis with an inexpensive and commercially available UV-A 9W lamp. In comparison to related photoactivated hydrophosphination reactions with [CpFe(CO)2]2 as a catalyst, these ruthenium-catalyzed reactions proceed at greater relative rates with lower catalyst loadings.

Published: August 2019

Construction of multifunctional metal-organic frameworks (MOFs) with asymmetric connectivity have the potential to expand the scope of their utilization. Herein, we report a robust 9-connected microporous Zr-based MOF, NU-300, assembled from asymmetric tri-carboxylate ligands and Zr6 nodes. As indicated by single-crystal X-ray diffraction analysis, there exist uncoordinated carboxylate groups in the structure of NU-300 that can participate in ammonia (NH3) sorption through acid-base interactions which yield high uptake of NH3 at low pressure regions (<0.01 bar). In situ infrared (IR) spectroscopy shows the interactions between Brønsted acidic sites and NH3, which suggests that NU-300 can be used as a sorbent for NH3 capture at low pressures.

Published: August 2019

Development of methods for economically feasible greener ammonia (NH3) production is gaining tremendous scientific attention. NH3 has its importance in fertilizer industry and it is envisaged as a safer liquid hydrogen carrier for futuristic energy resources. Here, an aqueous electrolysis based NH3 production in ambient conditions is reported, which yields high faradaic efficiency (~12%) NH3 via nitrogen reduction reaction (NRR) at lower over potentials (~ -0.6V vs. RHE or -1.1V vs. Ag/AgCl). Polycrystalline copper (Cu) and gold (Au) are used as electrodes for electrochemical NRR, where the electrolyte which yields high amount of NH3 (~41 µmol/L) is 5M LiClO4 in water with Cu as working electrode. A detailed study conducted here establishes the role of Li+ in stabilizing nitrogen near to the working electrode - augmenting the NRR in comparison to its competitor - hydrogen evolution reaction, and a mechanistic insight in to the phenomenon is provided. 15N2 assisted labeling experiments are also conducted to confirm the formation of ammonia via NRR. This study opens up the possibilities of developing economically feasible electrodes for electrochemical NRR at lower energies with only transient modifications of electrodes during the electrolysis, unlike the studies reported on complex electrodes or electrolytes designed for NRR in aqueous medium to suppress the hydrogen generation.
Influence of the Para-Substituent in Lanthanoid Complexes of Bistetrazole Substituted Calix[4]arenes
Authors: Phe Rene Z.H. , Skelton Brian , Massi Massimiliano , Ogden Mark
Published: August 2019

5,11,17,23-Tetra-tert-butyl-25,27-dihydroxy-26,28-bis(tetrazole-5-ylmethoxy)calix[4]arene has been reported to form remarkable Ln19 and Ln12 elongated clusters, upon addition of aqueous ammonium carboxylates. The impact of the para substituent on lanthanoid cluster formation has been studied by synthesising two new bis-tetrazole calixarenes, with p-H, and p-allyl substituents. Solution phase dynamic light scattering measurements of the reaction mixtures indicated that clusters are not formed with the p-H and p-allyl derivatives, in contrast with the behaviour of the t-butyl analogue. Lanthanoid complexes of the p-H and p-allyl calixarenes were characterised by single crystal X-ray diffraction, and were found to form mononuclear complexes, linked to form a one-dimensional coordination polymer for the p-allyl system. All of the complexes were isolated as ammonium salts, with ammonium cation included in the calixarene cavity in most cases. It is concluded that the nature of the para substituent has a profound impact on the lanthanoid cluster formation process, and derivatives with more subtle structural changes will be required to determine if additional lanthanoid “bottlebrush” clusters can be isolated.

To unveil the activation of dioxygen on the copper centre (Cu2O2core) of tyrosinase, we performed X-ray crystallograpy with active-form tyrosinase at near atomic resolution. This study provided a novel insight into the catalytic mechanism of the tyrosinase, including the rearrangement of copper-oxygen species as well as the intramolecular migration of copper ion induced by substrate-binding.
The Limited Predictive Power of the Pauling Rules
Authors: George Janine , Waroquiers David , Di Stefano Davide , Petretto Guido , Rignanese Gian-Marco , Hautier Geoffroy
Published: August 2019

The Pauling rules have served to analyze and rationalize crystal structures for decades. So far, there is no statistical answer on how these five rules perform. Here, we show the analysis of all five Pauling rules based on the geometrical data of around 5000 oxides. To do this, we determined the coordination environments of all 5000 oxides and compared our geometrical analysis to the prediction of the Pauling rules. We arrived at the conclusion that the Pauling rules - especially the electrostatic valence principle - perform poorly for most of the oxides: only 13% of all oxides simultaneously satisfy rules from two to five. To arrive at such an intuitive understanding of the stability of crystals that Pauling’s rules gave shortly after their development again, we should develop new and improved rules.

Published: August 2019

We here report the discovery of isoquinoline-based biaryls as a new scaffold for colchicine domain tubulin inhibitors. Colchicine domain inhibitors comprise a structurally diverse class of compounds offering highly desirable cytotoxic and vascular disrupting bioactivities. Current research on colchicine domain inhibitors is focused on improving in vivo robustness and tolerability: properties that are inextricably linked to the scaffold structure employed. The isoquinoline-based biaryl scaffold we now report offers high-potency tubulin inhibition with excellent robustness and druglikeness, allowing solubility, in vivo tolerability and facile late-stage structural diversification through a tolerant synthetic route. We have confirmed the tubulin-binding properties and mechanism of these isoquinoline-based biaryls through a series of cellular tests and established safe in vivo dosing parameters in mice. By addressing several problems facing the current families of inhibitors, we thus expect that this new scaffold will find a range of powerful in vivo applications towards translational use in cancer therapy.

placentárias petalógicas e outras poeiras viajantes
Authors: Mori Cecília
Published: August 2019

Em Placentárias petalógicas e outras poeiras viajantes, exposta na galeria da CAL em Brasília, o embate entre seus componentes se tornou explícito durante a mostra. Com a utilização de materiais antipáticos entre si, como por exemplo silicone e gra- xa, a forma dos objetos propostos se manteve em constante transformação física e cromática. Assim, a prática forasteira, de expor a ambigüidade dos (des)limites da arte, de seus espaços e de seus objetos está presente em Placentárias Petalógicas como em grande parte de minha produção poética. Como práticas do devir, as obras se formam e, no devir, as obras se deformam. A partir dessa percepção, minha prá- tica de ateliê se constitui na fracassada tentativa em domar cores e formas, nos mé- todos errantes de agrupar materiais, na inútil e boba insistência em nomeá-la, no indefinível caminho das experiências artísticas.

Published: August 2019

Distance education, mediated by Information and Communication Technologies, is increasingly present in the Brazilian educational scenario due to legislation incentives. In this modality, assessment to ensure effective learning, considering the particularities of distance education, represents a challenge to education managers. This research investigates the competences developed in two entirely distance-lectured courses in the Information Management degree of the Federal University of Paraná. For this purpose, the bibliographic and documental methodology was used to construct two assessment rubrics in the CoRubric platform, a data collection instrument for the research. Data are analyzed using statistical techniques. The results show the competences developed by students and those that need improvement, as well as the correlation between the characteristics of the courses and the learning and how much they affect the result. It concludes that the assessment rubrics constructed from CoRubric are capable of generating information for decision making in education.
Cenas do cotidiano escolar de surdos em Bragança, Pará
Authors: Santos Janaína de Sousa , Da Silva Luane Costa , Silva-Oliveira Gláucia Caroline
Published: August 2019

A Língua Brasileira de Sinais-Libras foi reconhecida como língua oficial no Brasil em 2002 e a partir de 2005, tornou-se disciplina obrigatória nos cursos de Licenciaturas e fonoaudiologia. Entretanto, ainda é pouco difundida na sociedade e nas escolas. Tal fato acentua as barreiras na interação entre surdos e ouvintes. Em busca de contribuir com esta interação, o projeto “Popularizando a Libras nas escolas Bragantinas” levou a cultura surda às escolas públicas de Bragança, Pará. Para isso, tornou-se necessário conhecer a realidade destes alunos, para intervir com ações direcionadas. Esta pesquisa é um estudo de caso da realidade encontrada nestas escolas públicas. Para isso, rodas de conversa trouxeram a vivência escolar dos surdos como tema central de discussão e interações, além de utilizar um checklist como instrumento para a coleta de informações referente às condições que interferem diretamente nas práticas pedagógicas escolares. As principais dificuldades registradas: acesso a Libras, metodologias direcionadas ao ensino de surdos e carência de intérpretes de Libras. A realidade dos surdos nas escolas regulares de Bragança está longe das asseguradas pelas leis vigentes e precisa de adequações para que o ensino de surdos se transporte do discurso e torne-se uma realidade na escola inclusiva.

La universidad en este momento, se constituye como el contexto propicio para encuentros e intercambio de saberes, mediados por lógicas y cosmovisiones salientes, que buscan su creencia y significación social. Este artículo científico es sustentado en el paradigma positivista, con enfoque cuantitativo. Tiene como objetivo general, crear principios metodológicos referentes a las competencias investigativas del docente, construidas durante su formación universitaria. Apoyada con referentes teóricos como los de Gallardo (2003); Ordóñez (2017), entre otros. La metodología es de tipo descriptiva, apoyada en un diseño de campo, donde se aplicará un estudio para docentes adscritos a la Universidad de Los Andes, Núcleo Universitario “Rafael Rangel” (ULA-NURR), estado Trujillo. De acuerdo con los planteamientos investigados en el artículo, se concluye que es de esperar que los estudiantes al momento de producir conocimiento en el proceso investigativo sean capaces de establecer relaciones de conexión entre teoría y práctica. Además, en el desempeño de su accionar investigador el estudiante deberá adquirir nuevos conocimientos para un eficiente desarrollo de las competencias investigativas y así puedan generar producciones científicas en pro de la sociedad del entorno al que pertenezcan.
Lógica Cósmica Educativa en la Pedagogía
Authors: Rodríguez Pinto José Gregorio , Donoso Balboa Carolina Antonieta
Published: August 2019

El propósito de este ensayo está orientado a la exploración de las perspectivas teóricas relacionadas con la lógica cósmica educativa aplicada en la pedagogía. En este sentido, Sagan (1987): define al cosmos como algún punto entre la inmensidad y la eternidad, de cuya comprensión depende el futuro de toda la vida. Asimismo, el prólogo de Chopra en la obra de Shrestha (2006): expresa que el micro cosmos, es dirigido por la vibración de cuerdas superiores con resonancia en el ser humano en términos energéticos dentro de un continuo espacio-tiempo. En el contexto educativo, Maturana (2010): propone que es vital crear una consciencia social ética y ecológica. Adicionalmente, Chamon (2006): destaca que lo pedagógico es complejo por lo que aplica una lógica fenomenológica para su desarrollo y según Morín (2000): un aprendizaje de la convivencia. En esta misma línea de pensamiento, Niño (1998): reconoce la concepción de la vida humana como proyecto e interminable tarea pedagógica. Por otro lado, Gadotti (2002): propone una Pedagogía de la Tierra o Ecopedagogía. En sintonía con esta perspectiva, Sánchez, Peters, Márquez, Vega, Portales, Valdez y Azuara (2005): sugieren incorporar a la educación nuevas prácticas. Para consolidar esta visión, las experiencias con Maestros no humanos constituyen una de las alternativas pedagógicas más innovadoras. De acuerdo a estas consideraciones, se concluye que la visión cosmobiológica de la educación es esencial para construir y hacer fluir una comprensión empática entre todos los seres sintientes de la red universal.

Concrete block pavements have become an attractive engineering and economical alternative to both flexible and rigid pavements because of it’s high strength and durability. The influence of pozzolanic mineral additions – natural zeolite and expanded perlite powder on the properties of concrete interlocking blocks in different curing conditions has been studied. The use of zeolite as a substitute for cement in the production of concrete blocks increased the water demand but decreased the water absorption of the blocks. Obtained results show, that concrete blocks with 10% substitution of cement with zeolitic tuff is characterized by higher strength, lower mass loss and absence of efflorescence.

The research of railway track surfaces is aimed at improving the quality of railway infrastructure and providing the chance of improving the safety of driving. Therefore, it is advisable to constantly monitor track surface, but the research itself is not innovative because it is based on a known procedure. The crucial element are the techniques that allow to delve into the sources of problems. The aim of the article is to use the selected instruments of quality management to analyze the causes of track twist at high (180 km/h) speed of driving. The analysis of the causes of track twist was done on the basis of results from the measurement of one kilometer track section of the Krakow Glowny - Medyka route, which was made by using the TEC measuring device in April 2018. It was inferred that it is impossible to reach 180 km/h without track twist. In order to identify the causes of track twist it was proposed to use the selected sequence of quality management instruments, i.e.: brainstorming, Ishikawa diagram and the 5Why method. The identified causes of track twist include the abrasion of rail, scratches and exploitation point. The analysis and conclusions drawn from it may be useful in the analysis of other problems in railway transport as well as production and service industries.
Reversible Supply Chain in function of competitiveness
Authors: Drljača Miroslav
Published: August 2019

Supply Chain makes the flow of goods, services and information from suppliers, through transport, producers, distributors, retailers to end customers. Big producers opt for a strategy of outsourcing logistic services, especially storage, delivery, and distribution services to end-customers. Commitment to the strategy of outsourcing, at the same time, is the strategy of focus on the core business. Small producers, especially manufacturers of agricultural food products, have recently opted to avoid intermediaries in the transport and distribution of the product to the end customer. All in order to increase the quality of their own products and increase the competitiveness by eliminating the costs of intermediaries in transport and distribution. This is achieved by merging and shortening the supply chain. The EU has established an institutional framework regulating the operations of producers through a short supply chain. The market situation requires further optimization by producers due to lack of labour and the need to increase competitiveness and leads to the emergence of a reversible supply chain phenomenon. In the paper, the author, by applying general and special scientific methods of cognition, explores the advantages and shortcomings of the short and reversible supply chain, derived from the traditional and modern supply chain model.
