Authors: Alvarado Pérez Eddy Antonio , Amador Coronado José Manuel , Centeno Bravo Blanca Nevai 
Published: October 2019

La investigación se realizó con la finalidad de valorar los medios didácticos empleados en el proceso de aprendizaje en la disciplina de Lengua y Literatura a estudiantes de octavo grado, Colegio “Pablo Antonio Cuadra” Nº3, Puerto Príncipe, II semestre, 2013. Los recursos educativos, medios didácticos para el proceso de aprendizaje, son indispensable para el desarrollo de los contenidos, en donde el estudiantado es más que un receptor de información se convierte en un investigador, crítico y vocero de su entorno.
La creación y uso de los medios didácticos como recursos de aprendizaje es de gran valor para lograr de manera integral la participación activa del estudiantado, el cual debe ser una de las prioridades para alcanzar un producto de calidad que promueva la eficacia y desarrollo en todos los ámbitos de la vida, permitiendo al educador fijar la intencionalidad pedagógica y alcanzar aprendizajes significativos. Este estudio fue descriptivo y enfoque cualitativo, la que nos permitió especificar datos sin medición numérica y describir los comportamientos de los sujetos de investigación mediante los instrumentos aplicados como entrevistas a docentes, estudiantes y director del centro educativo; la guía de observación nos dio los elementos necesarios para identificar los medios didácticos empleados en la asignatura de Lengua y Literatura. La unidad de análisis fueron 23 estudiantes de los cuales estuvieron constituidos por 13 mujeres y 10 varones. Los resultados más relevantes de la investigación se centran en el poco uso de medios didáctico empleados por el docente en el proceso de aprendizaje.

Modernisering van het Europese consumentenrecht: meer vlees op het bot (I)
In eerdere publicaties ben ik ingegaan op de Mededeling ‘Een New Deal voor consumenten’ en het daarmee samenhangende voorstel voor een moderniseringsrichtlijn. In dit artikel bespreek ik de verdere voortgang van het richtlijnvoorstel, waar inmiddels politieke overeenstemming over is bereikt. Daarin staat de vraag centraal of de moderniseringsrichtlijn in haar uiteindelijke vorm de in de New Deal-mededeling gedane belofte waarmaakt van modernisering en verbetering van de handhaving van het consumenten-acquis. In het eerste deel van deze bijdrage richt ik mij daartoe op de individuele en publiekrechtelijke handhaving van het consumentenrecht en op dynamic pricing en informatieverplichtingen voor online marktplaatsen. In het tweede deel ga ik in op de vraag met wie de consument eigenlijk contracteert als de overeenkomst via een online marktplaats wordt gesloten, op enkele vereenvoudigingen voor handelaren en op de herziene regels voor de bedenktijd van consumenten. Ik rond dan af met een conclusie. Voorstel van 11 april 2018 voor een Richtlijn van het Europees Parlement en de Raad tot wijziging van Richtlijn 93/13/EEG van de Raad van 5 april 1993, Richtlijn 98/6/EG van het Europees Parlement en de Raad, Richtlijn 2005/29/EG van het Europees Parlement en de Raad en Richtlijn 2011/83/EU van het Europees Parlement en de Raad wat betreft betere handhaving en modernisering van de regels voor consumentenbescherming in de EU, COM(2018) 185 final; Tekst politiek akkoord richtlijnvoorstel van 29 maart 2019, Openbaar register van Raadsdocumenten, Interinstitutioneel dossier 2018/0090(COD), nummer document: ST 8021 2019 INIT.

Nationale veiligheid en buitenlandse investeringen
In reactie op de toenemende aandacht voor geopolitieke belangen in het kader van buitenlandse investeringen is recent een Europese verordening aangenomen en is een Nederlands wetsvoorstel voor de Wet ongewenste zeggenschap telecommunicatie (WOZT) aanhangig gemaakt. De Europese Verordening (EU) 2019/452 tot vaststelling van een kader voor de screening van buitenlandse directe investeringen in de Europese Unie creëert een Europees kader op het gebied van de screening van buitenlandse investeringen op grond van veiligheid of de openbare orde. De verordening is een hybride instrument dat (1) coördinatie tussen nationale screeningsautoriteiten faciliteert, (2) in een mate van harmonisatie voorziet en (3) formele Europese bevoegdheid op het gebied van screening van buitenlandse investeringen introduceert. De lidstaten blijven in het licht van hun soevereiniteit op het gebied van nationale veiligheid echter de uiteindelijke verantwoordelijke voor de vraag of een investering al dan niet wordt geblokkeerd op grond van de nationale veiligheid of openbare orde. Op grond van de WOZT krijgt de minister de bevoegdheid het verkrijgen of houden van overwegende zeggenschap in een telecommunicatiepartij te verbieden op grond van een bedreiging van het publiek belang. Omdat de ‘bedreiging van het publiek belang’-norm limitatief en zeer specifiek is gedefinieerd, zal de minister enkel in uitzonderlijke gevallen het verkrijgen of houden van overwegende zeggenschap kunnen verbieden.Verordening (EU) 2019/452 tot vaststelling van een kader voor de screening van buitenlandse directe investeringen in de Europese Unie (PbEU 2019, L 791/1); Wet ongewenste zeggenschap telecommunicatie (Kamerstukken II 2018/19, 35153, 2 (Wetsvoorstel) en 3 (MvT).

Context.—Biomedical terminologies such as Logical Observation Identifiers, Names, and Codes (LOINC) were developed to enable interoperability of health care data between disparate health information systems to improve patient outcomes, public health, and research activities.Objective.—To ascertain the utilization rate and accuracy of LOINC terminology mapping to 10 commonly ordered tests by participants of the College of American Pathologists (CAP) Proficiency Testing program.Design.—Questionnaires were sent to 1916 US and Canadian laboratories participating in the 2018 CAP coagulation (CGL) and/or cardiac markers (CRT) surveys requesting information on practice setting, instrument(s) and test method(s), and LOINC code selection and usage in the laboratory and electronic health records.Results.—Ninety of 1916 CGL and/or CRT participants (4.7%) responded to the questionnaire. Of the 275 LOINC codes reported, 54 (19.6%) were incorrect: 2 codes (5934-2 and 12345-1) (0.7%) did not exist in the LOINC database and the highest error rates were observed in the property (27 of 275, 9.8%), system (27 of 275, 9.8%), and component (22 of 275, 8.0%) LOINC axes. Errors in LOINC code selection included selection of the incorrect component (eg, activated clotting time instead of activated partial thromboplastin time); selection of panels that can never be used to obtain an individual analyte (eg, prothrombin time panel instead of international normalized ratio); and selection of an incorrect specimen type.Conclusions.—These findings of real-world LOINC code implementation across a spectrum of laboratory settings should raise concern about the reliability and utility of using LOINC for clinical research or to aggregate data.

AbstractHeart failure (HF) is a leading cause of death worldwide. The most common conditions that lead to HF are coronary artery disease, myocardial infarction, valve disorders, high blood pressure, and cardiomyopathy. Due to the limited regenerative capacity of the heart, the only curative therapy currently available is heart transplantation. Therefore, there is a great need for the development of novel regenerative strategies to repair the injured myocardium, replace damaged valves, and treat occluded coronary arteries. Recent advances in manufacturing technologies have resulted in the precise fabrication of 3D fiber scaffolds with high architectural control that can support and guide new tissue growth, opening exciting new avenues for repair of the human heart. This review discusses the recent advancements in the novel research field of fiber patterning manufacturing technologies for cardiac tissue engineering (cTE) and to what extent these technologies could meet the requirements of the highly organized and structured cardiac tissues. Additionally, future directions of these novel fiber patterning technologies, designs, and applicability to advance cTE are presented.

Published: October 2019

AbstractHerein, emerging applications of luminescent semiconductor nanocrystals are addressed, such as quantum dots and quantum rods as down‐conversion materials used in liquid crystal displays (LCD). Their precisely tunable emission wavelengths and narrow emission bandwidths offer high color purity resulting in a wide color gamut with vivid colors for LCDs. Anisotropic materials, such as quantum rods, have the additional advantage of polarized emission, which can bring a significant improvement to the efficiency of LCD displays. The basic optical properties of these nanomaterials are considered, with a focus on quantum rods, and the challenges and progress in their assembly are discussed. Different techniques for quantum rod alignment are introduced such as shear‐oriented, electric field and magnetic field assisted assembly, mechanical rubbing, stretching, and electrospinning. The photoalignment approach allows for an easy arrangement of quantum rods in‐plane, and the implications of this method to patterning are considered. Different configurations of LCDs utilizing semiconductor quantum dots and quantum rods as down‐conversion layers are also presented, and the potential applications that are enabled by the wide range of emerging materials are highlighted.

AbstractJejunogastric intussusception (JGI) is a rare long‐term complication of Billroth II gastrectomy. It presents potentially lethal complication of gastrectomy or gastrojejunostomy which can occur any time after a gastric operation. Delayed diagnosis can lead to high morbidity and even mortality. Prompt surgical intervention is mandatory after early diagnosis. Endoscopy and abdominal computed tomography (CT) scanning are the main diagnostic tools. For gastric surgery patients who later experience sudden onsets of epigastric pain, vomiting, or subsequent hematemesis, JGI should be considered. A 77‐year‐old man who had a Billroth II gastrectomy 30 years prior to admission presented to our emergency department due to multiple episodes of epigastric colicky pain and hematemesis. He underwent esophagogastroduodenoscope and an abdominal CT scan. We provided a systemic image description of a rare case of internal herniation with retrograde JGI into the stomach. The patient received emergent laparotomy and resection of the efferent loop of the jejunum with the gangrenous segment. He was discharged 10 days after admission. JGI is a rare but potentially fatal disease. Early diagnosis and surgical treatment are important to avoid subsequent high mortality.

AbstractThis proof‐of‐concept study tests the initial efficacy of the Building a Strong Identity and Coping Skills (BaSICS) intervention, a selective prevention of internalizing problems program for early adolescents exposed to high levels of poverty‐related stress. Eighty‐four early adolescents (Mage = 11.36 years) residing in very low‐income neighborhoods were randomized to receive the 16‐session intervention (n = 44) or to an assessment‐only control condition (n = 40). BaSICS teaches coping skills, social identity development, and collective social action to empower youth with the ability to connect with members of their communities and cope with poverty‐related stress in positive and collaborative ways. Pretest–posttest analyses showed that intervention adolescents acquired problem‐solving and cognitive‐restructuring skills and reduced their reliance on avoidant coping. In addition, HPA reactivity was significantly reduced in the intervention youth, but not controls. Finally, intervention youth's internalizing and somatic symptoms as reported by both youth and their parents, showed significant reductions over time, whereas control youth had no such changes. Results provide strong support for this approach to strength‐building and symptom reduction in a population of early adolescents exposed to poverty‐related stress.

Published: October 2019

AbstractThe silaboration of [1.1.1]propellane enables direct introduction of B and Si functional groups onto the bicyclo[1.1.1]pentane (BCP) scaffold in high yield under mild, additive‐free conditions. The silaborated BCP can be obtained on a gram‐scale in a single step without the need for column‐chromatographic purification, and is storable and easy to handle, providing a versatile synthetic intermediate for BCP derivatives. We also describe various conversions of the C−B/C−Si bonds on the BCP scaffold, including development of a modified Suzuki–Miyaura cross‐coupling reaction at the highly sterically hindered bridgehead sp3 carbon center of the BCP skeleton using a combination of highly activated BCP boronic esters, copper(I) oxide, and a PdCl2(dppf) catalyst system.
Effect of nanosilica with different interfacial structures on mechanical properties of polyimide/SiO2 composites
Authors: Liang Mengfan , Wang Yu , Sun Shuhong , Yang Wenlong 
Published: October 2019

ABSTRACTIn this article, the effects of coupling agent, silica particle size, and particle shape on the mechanical properties of polyimide (PI) were studied by molecular dynamics (MD) simulations, and the effect of SiO2 surface treated with coupling agent on the mechanical properties of PI was investigated by experiment. At the same doping volume fraction (5%), the simulation results show that the surface interaction energy between the matrix and particle gradually increases with the radius of the embedded nanoparticles. Meanwhile, the interface interaction energy and mechanical properties of the sphere‐type were significantly higher than the ones of other shaped nanoparticles. Moreover, the simulations were compared with the experimental results; atomic force microscopy and scanning electron microscopy images can verify that after being treated with coupling agent, interface interaction between nanosilica and PI enhances quite a little. The mechanical experimental results show that the tensile strength and elasticity modulus of pure PI, unbonded (UB) PI/SiO2, and bonded PI/SiO2 films are 34.47 and 1.13, 36.46 and 1.32, and 66.20 MPa and 1.72 GPa, respectively. It is indicated that the coupling agent plays a crucial role in nanocomposites. © 2019 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2020, 137, 48595.

AbstractThis study presents a background estimation for the CubeSats Applied for MEasuring and LOcalising Transients (CAMELOT), which is a proposed fleet of nanosatellites for the all‐sky monitoring and timing‐based localization of gamma ray transients with precise localization capability at low Earth orbits. CAMELOT will allow us to observe and precisely localize short gamma ray bursts (GRBs) associated with kilonovae, long GRBs associated with core‐collapse massive stars, magnetar outbursts, terrestrial gamma ray flashes, and gamma ray counterparts to gravitational wave sources. A fleet of at least nine 3U CubeSats is proposed to be equipped with large and thin CsI(Tl) scintillators read out by multipixel photon counters (MPPC). A careful study of the radiation environment in space is necessary to optimize the detector casing, estimate the duty cycle due to the crossing of the South Atlantic Anomaly and polar regions, and minimize the effect of the radiation damage of MPPCs.
Thermische Analyse einer Dachbegrünung mit Moosmatten
Authors: Port Lukas , Goeke Johannes 
Published: October 2019

AbstractObwohl vor Jahrzehnten der Energiebedarf von Gebäuden noch eine untergeordnete Rolle gespielt hat, wurden bereits früh die thermischen Vorteile von Dachbegrünungen genutzt. Beispielsweise lassen Funde von Grassodenhäuser in Island auf das Jahr 1000 n. Chr. schließen. Auch findet sich immer wieder der spezielle Baustil dicker Grasplatten als Dach an Orten mit extremen Klimaschwankungen.In der hier vorliegenden Studie werden Moosmatten auf ihre Wärmeleitfähigkeit (λ) und den thermischen Widerstandswert (R‐Wert) untersucht. Im Fokus stehen dabei sowohl der strukturelle R‐Wert ohne Änderung des Wassergehalts als auch der effektive R‐Wert, der insbesondere durch die Änderung der latenten Energie gekennzeichnet ist. Die Ergebnisse werden mit den Resultaten ähnlicher Dachbegrünungen von Studien anderer Autoren der letzten Jahre verglichen und in Beziehung gesetzt. Damit sollen die Berechnung der thermischen, energetischen Aktivität der Gebäudehülle unterstützt und die Transmissionswärmeverluste quantifizierbar werden.

AbstractIncreasing bone formation on the surfaces of implants such as screws, plates, or shims holds great significance for clinical medicine. However, osteogenesis implant coatings that mimic natural bone in terms of both their components and structural features are still lacking. Here we report the biomimetic interface of calcium phosphate (CaP) in a collagen matrix fabricated by controlled mineralization that presents biomimetic porous features. The porous CaP/collagen interface, with a thickness of about 1 μm, significantly enhances osteogenesis, as verified at both the gene and protein levels as well as by in vivo experiments. Taking advantage of the generality of the method, the biomimetic interface was prepared on a variety of substrates, including conductive substrates, 3D metal meshes, plastic or elastic substrates, and even on filter papers. The adjustability and generality of the method have enabled new characterization tests to be developed during experiments on cells and thus should greatly facilitate clinical medicine and tissue engineering.
Proton impact charge exchange and excitation cross sections for liquid Sn divertor studies
Authors: Janev Ratko K. , Jakimovski Dragan 
Published: October 2019

AbstractThe quantum dynamics of charge exchange (electron capture) and excitation processes in proton collisions withSnatoms is studied for the first time by using the two‐centre atomic orbital close coupling method. The expansion basis includes the lowest nine states of singlet and triplet symmetry ofSnand all the states withn ≤ 8 of theHatom. The spin‐resolved state‐selective charge exchange (up ton = 5) and excitation cross sections are calculated in the energy range of0.5 − 100 keV. Strong coupling between the electron capture and excitation channels is observed in the low‐energy(E ≤ 10 keV)region associated with the energy quasi‐resonance of some projectile and target states. The intensities of some strong Sn spectral lines are also calculated for a number of typical tokamak edge plasma temperatures.
Numerical study of an electrostatic plasma sheath with non‐thermal electrons and charged nanoparticles
Authors: Khalilpour Habib , Foroutan Vahid 
Published: October 2019

AbstractNumerical solutions of the multi‐fluid equations are used to investigate the effects of non‐thermal electrons on the structure of an electrostatic plasma sheath in the presence of nano‐sized dust grains. It is assumed that electrons obey the Cairns distribution [Cairns et al. Geophys. Res. Lett. 22, 2709 (1995)], with a parameter α that determines the effect of non‐thermal electrons and shows the deviation from the Maxwellian distribution. The results revealed that sheath parameters are strongly modified in the presence of non‐thermal electrons and with increasing α the sheath width increases. With the increase in α, the absolute dust charge increases while the dust density is reduced.
