Visibility of subsurface nanostructures in scattering-type scanning near-field optical microscopy imaging
Authors: Zhang Wenhao , Chen Yuhang
Published: February 2020

Detecting structures below a cover film at the nanoscale resolution is of essential importance. In this work, we explored factors affecting subsurface material contrast and structural visibility in scattering-type scanning near-field optical microscopy (s-SNOM). A kind of multilayered reference samples containing different buried structures was fabricated and applied for s-SNOM imaging. The dependence of near-field optical contrast on structure geometry, dimension and cover thickness was investigated. Results demonstrate that distinguishing the buried slit pattern is easier than the circular hole with the same critical dimension. The s-SNOM can sense material difference under a more than 100 nm thick polymethyl methacrylate layer and it has a subsurface spatial resolution better than 100 nm.

We build a compressive imaging system that can reconstruct high-speed videos of two fields-of-view by capturing a single frame. A single digital micromirror device is employed to implement high-speed modulation simultaneously on both scenes in a manner that does not compromise spatial resolution. We utilize deep denoising priors in the plug-and-play framework for efficient reconstruction. Two spatial–temporal data cubes, each with the size

Published: February 2020

Soliton solutions are studied for paraxial wave propagation with intensity-dependent dispersion. Although the corresponding Lagrangian density has a singularity, analytical solutions, derived by the pseudo-potential method and the corresponding phase diagram, exhibit one- and two-humped solitons with almost perfect agreement to numerical solutions. The results obtained in this work reveal a hitherto unexplored area of soliton physics associated with nonlinear corrections to wave dispersion.

Published: February 2020

Die Einführung und Nutzung von Technologien erzeugt auch im Sozialwesen neue, zum Teil feldspezifische Herausforderungen. Diese zeigen sich beispielhaft in Werkstätten für Menschen mit Behinderung (WfbM), einem mit deutschlandweit rund 730 Einrichtungen und über 310.000 arbeitnehmerähnlich Beschäftigten großen Bereich zur Sicherung der Teilhabe an Arbeit. Dieser ist durch sein spezifisches Tripelmandat aus Rehabilitation, Inklusion und Wirtschaftlichkeit in hohem Maße mit dem Dilemma zwischen individualisierter Fürsorge, effizienter Produktion und Vermittlung auf den allgemeinen Arbeitsmarkt konfrontiert. Auf Basis einer Fallstudie in einer WfbM werden feldspezifische Deutungen, Herausforderungen und Umgangsweisen im Zusammenhang mit digitalen Transformationsprozessen beschrieben und auf das Tripelmandat unter Bedingungen von Digitalisierung bzw. Technologisierung bezogen.
Reconceptualizing register in a continuous situational space
Authors: Biber Douglas , Egbert Jesse , Keller Daniel
Published: February 2020

Corpus-based methods for the quantitative linguistic description of registers are well established. In contrast, situational analyses of registers have been based on qualitative descriptions of categorical situational characteristics. In the present study, we address this inconsistency by describing the variation among texts and registers in a continuous (quantitative) situational space. We describe “registers” as categorical constructs – culturally recognized categories of texts – but propose that they should be described in continuous terms. Such descriptions allow quantitative comparisons of registers, as well as analysis of the extent to which a register is well-delimited in terms of its situational characteristics.

Applying this analytical framework, we also explore a deeper issue: the possibility that some texts are not instantiations of any culturally-recognized register category. Both issues are tackled through analysis of a corpus of web documents. We first identify quantitative situational dimensions of variation, employing the methods of multi-dimensional (MD) analysis. We then describe how the situational characteristics of texts and registers can be analyzed in a continuous MD space. And finally, we propose analysis ofsituational text types– categories that are statistically well-defined in their situational characteristics – as an approach to describing all texts, including texts that do not belong to a culturally recognized register category.
Phase transformation involved in the reduction process of magnesium oxide in calcined dolomite by ferrosilicon with additive of aluminum
Authors: Ma Hongzhou , Wang Zhixian , Wang Yaoning , Wang Dingding
Published: February 2020

Metal magnesium is mainly produced from the calcined dolomite by the silicothermic production. However, in this process, the reduction temperature is higher while the reaction speed is slow, which results in higher energy consumption and serious environmental problems. In this paper, adding aluminum into the ferrosilicon reducing agent is expected to lower the reaction temperature so as to solve the problems above. The phase transition involved in the whole reduction process including with and without aluminum addition were investigated in details by theoretical calculation and experimental research. The influence of aluminum on the magnesium oxide reduction path was analysis to clarify the internal mechanism. The results show that aluminum added into the ferrosilicon would first react with magnesium oxide to form magnesium vapor and alumina under vacuum pressure of 10 Pa when the temperature rises to 720°C. Then, calcium aluminate would be formed by the reaction of aluminum oxide and calcium oxide. Once the temperature reaches 1150°C, silicon begins to reduce the magnesium oxide to create the silicon oxide that will finally react with calcium oxide to form calcium silicate. When the temperature rises above 1150°C, both the aluminum and silicon will participate in the reduction of magnesium oxide. In the process of heating up, the mixture of aluminum, ferrosilicon and calcined dolomite forms Mg2Al4Si5O18 and Ca3Al2(OH)12 phase with the components in calcined dolomite. Mg2Al4Si5O18 and Ca3Al2(OH)12 phase finally form Ca12Al14O33 phase. The interaction between aluminum and ferrosilicon in the mixture is less; the mixture of aluminum and ferrosilicon first forms Al3FeSi2 phase, and finally has the trend of forming Al4.5FeSi phase. There is a great difference between the phase transformation of aluminum in the mixture of aluminum, ferrosilicon and calcined dolomite and that of aluminum in the mixture of aluminum and ferrosilicon.
Towards a Theoretical Framework for Social Impact Bonds
Authors: Albertson Kevin , Fox Chris , O’Leary Chris , Painter Gary
Published: February 2020

Governments in some of the world’s richest nations appear to be caught in a double challenge of declining social budgets even as social needs are increasing. In this context, Outcomes Based Commissioning (OBC), has been suggested as one way in which ‘more’ social services can be provided for ‘less’ public resources. This form of commissioning is often linked with a new financing tool for social services, referred to in the US as ‘Pay for Success and Payment by Results in the UK or as a ‘Social Impact Bond’ (SIB). However, to date, this approach is under-theorised and this is a limiting factor both for shaping a research and evaluation agenda around SIBs and in understanding how such instruments might develop in future. Without a theoretical rationale for SIBs, it is not straightforward to assess whether, and how well, they have achieved their goals, and how they might be developed further. In this paper we consider two broad approaches to theorising SIBs. One draws on public administration theories, the other on innovation theories. To date, SIBs have often been theorised as the logical next step in the New Public Management (NPM). But NPM itself is a contested theory and recent theoretical innovations in public administration, particularly the concept of New Public Governance might provide a more useful theoretical framework. A second broad approach through which to understand SIBs is their potential to improve the rate and dissemination of innovation. There are many different innovation models that might be applied to better understanding of SIBs. We look first at the concept of Open Innovation with its focus on distributed innovation processes in which knowledge flows across organisational boundaries and more recent articulations – Open Innovation 2.0 – which place greater emphasis on mixed economy collabarations involving: industry; government; universities; and communities and users (the so-called ‘quadruple helix’) to solve societal challenges. We go on to consider social innovation, with its clearer focus on using social means to deliver social outcomes and whether SIBs can be theorised through this lens. No one model is entirely satisfactory as an explanatory framework for SIBs and we conclude by suggesting that a supporting theory combining NPG with elements of Open Innovation 2.0 and social innovation might be a productive approach for shaping future research and, in addition, might suggest some future directions for the next generation of SIBs.
Anticholinergic drugs and oral health-related quality of life in patients with schizophrenia: a pilot study
Authors: Chapuis Justine , Siu-Paredes Francesca , Pavageau Claire , Amador Gilles , Rude Nathalie , Denis Frédéric
Published: February 2020

Objective

The aim of this study was to explore, in a sample population of people with schizophrenia (PWS), the role of the anticholinergic burden on the perception of oral health-related quality of life (OHrQoL) in France.

Methods

A pilot study was performed between March 2014 and January 2016. PWS were recruited from a population in Côte d’Or department in France. Dental status was investigated using the Decayed, Missing, or Filled Teeth (DMFT) index, the Xerostomia Index (XI), and the Global Oral Health Assessment Index (GOHAI) for OHrQoL. The anticholinergic impregnation score was recorded using the anticholinergic impregnation scale (AIS).

Results

A sample of 62 people was selected. The DMFT score was 16.5± 8.7, the XI score was 22.9±7.8, the GOHAI score was 43.0±8.8, and the AIS score was 3.1±2.8. In total, 169 drugs were prescribed to the people of our sample, and 114 different anticholinergic drugs were observed. The most frequently used anticholinergic drugs (51.40%), in the study had a low antimuscarinic potency (1 point according to AIS scale). The multiple linear regression model showed that the OHrQoL scores were significantly lower when the DMFT scores, XI score, and anticholinergic scores were high.

Conclusions

This pilot study highlighted the potential role of the anticholinergic burden on the OHrQoL of PWS. A study with a validated specific scale for the OHrQoL and a standard anticholinergic burden scale should be conducted to clarify the role of anticholinergic drugs on the OHrQoL for PWS.

Leveraging Stakeholders to Cover Budgetary Shortfalls in U.S. National Parks: Lessons from the 2018/2019 Government Shutdown and Joshua Tree National Park
Authors: Facemire Challie R.
Published: February 2020

Joshua Tree National Park is a remarkable desert ecosystem made iconic by the famed Joshua trees that dot the landscape. In 1994, a majority of Joshua Tree’s holdings were designated as “wilderness” (a legal status in the U.S.). Subsequently, Joshua Tree was buffeted by deleterious anthropogenic forces and suffered from severe budgetary constraints. In 2018/2019, a U.S. Government shutdown forced the Joshua Tree staff into furlough, while the park remained open to visitors. The response of local volunteers, who took responsibility for educating visitors about park policies and ecosystem conservation in the midst of the shutdown, shows the extent to which networks of local and community volunteers can be mobilized to mitigate at least some of the effects of budgetary constraints that affect the wilderness and national park lands.
Divesting from Ethnomusicology
Authors: Fox Aaron A.
Published: February 2020

This response to Amico’s paper draws lessons from the author’s own career to endorse Amico’s call to rename the discipline of “ethnomusicology,” while cautioning against the risks of nominalism as a sufficient response to the underlying tensions animating dissatisfaction with the current name of the discipline. The response emphasizes points of convergence and divergence between diverse disciplinary practices of music scholarship and locates a problem for efforts to synthesize such practices in competing views of science and applied research, and indeed in competing concepts of “music” as such.
For Transdisciplinarity
Authors: Waltham-Smith Naomi
Published: February 2020

This response situates Stephen Amico’s provocation within the context of an intimate connection between postcolonial thought and the drive towards interdisciplinarity. It examines via three critical moments the deeply intertwined desires to destroy the colony on the one hand and disciplinarity on the other. To this end it analyses the debates around interdisciplinarity between Gayatri Spivak, Homi Bhabha, and Laurent Dubreuil, before turning to the explicit thematization of transdisciplinarity as part of the neoliberalization of the university. Finally, the essay turns to Hélène Cixous’s reflections in “Mon Algériance” to develop another way of thinking about the irreducible dispersal and dissemination of disciplinarity and its imbrication in the (post)colonial.

Abstract:Domestic violence is a behavior that can be categorized as a violation of human rights. Because this behavior results in disruption of the social dimension of humanity, due to actions that do not humanize humans in general. Even in the context of domestic violence, the perpetrators who are supposed to protect even commit acts of violence, mistreatment, intimidation and even the loss of the victim's life. The research method uses the normative juridical method, using secondary data obtained through literature study and analyzed qualitatively. The results and discussion of this study are that there are aspects of human rights violations that occur in domestic violence behavior. So the government is obliged to take action in the form of legal protection for victims by ensnaring the perpetrators with laws and regulations.

Published: February 2020

Scintillator detector have been used in a wide range of experiments in different areas: Nuclear and High Energy Physics, Medicine, and Radiation Security among others. It is common to use scintillator counters coupled to Photomultiplier Tubes (PMT) as a read out detectors. Nowadays, there has been a great interest in using the Silicon Photomultipliers (PMSi) as a replacement for PMT's due to their high photon detection efficiency (PDE) and their high single photon time resolution (SPTR). The fast the signal is detected, the whole detection system will be useful to search for new physics. PMSi is also known to have a good compactness, magnetic field resistance and low cost. In our lab we are measuring the time resolution of two different models of PMS in order to build a fast radiation detector system.

Cuando se decide cambiar una terapia antirretroviral se puede llegar a limitar futuras opciones‚ y es allí donde las conductas del personal tratante deben ser las más acertadas. Se realizó un estudio transversal-descriptivo‚ revisando las principales causas de cambios de esquema en los pacientes VIH de la IPS CEPAIN de Bogotá (Colombia) durante el periodo 2015-2017. Los cambios de tratamiento se estimaron en 8,1%; 8,8% y 5,8% durante los 3 años, el principal motivo de cambio fueron las reacciones adversas con 53,1%; 46%, y 49,6% respectivamente‚ seguidos de simplificación con 17,5; 25,1 y 26,5% y fracaso terapéutico en 19,8; 20,9 y 14,8% para cada año. Durante el primer año de tratamiento existió la necesidad de cambiar los esquemas en 12,9; 18,5, y 7,6% de los pacientes que iniciaron tratamiento en esos respectivos años. Las decisiones en los cambios de tratamiento antirretroviral involucran la introducción de nuevos antirretrovirales, la necesidad de reducir el número de tabletas o medicamentos, distintos perfiles de eficacia, tolerancia, efectos secundarios, toxicidad, barrera genética e interacciones. Otros factores a tener en cuenta son: el costo creciente de los medicamentos antirretrovirales, la dinámica en la transición y aplicación de los nuevos esquemas para garantizar un enfoque clínico, y económico sustentable.

Authors: Lopez Anthony , Herazo Katerine , Sotomayor Reinaldo G.
Published: February 2020

El ibuprofeno es uno de los fármacos más utilizados e indicado para terapias antiinflamatorias, dolor, entre otras patologías. Sin embargo, este fármaco presenta una baja y errática biodisponibilidad, debido a la pobre solubilidad acuosa intrínseca del mismo, por lo cual esta categorizado como clase II en el sistema de clasificación biofarmacéutica. El objetivo de este trabajo fue desarrollar, diseñar y evaluar un sistema de entrega de fármaco autoemulsificable (SEDDS) para mejorar la solubilidad y velocidad de disolución de ibuprofeno.Aceites, cosolventes, tensioactivos y portadores porosos fueron evaluados por su capacidad de mejorar la solubilidad del ibuprofeno, habilidad de autoemulsificación, robustez en diferentes pH y capacidad de adsorción. El aceite de coco, Tween 80 y propilenglicol lograron un aumento significativo de la solubilidad acuosa del ibuprofeno en un tiempo de autoemulsificación menor a 2 minutos. Neusilin US2® fue seleccionado como portador, dando como resultado un pequeño granulo de excelente fluidez, que permitió obtener comprimidos que cumplieron satisfactoriamente las pruebas de control de acuerdo con las especificaciones establecidas. Los SEDDS líquidos y sólidos son una alternativa de formulación ventajosa y prometedora para mejorar la solubilidad de fármacos pobremente solubles de acuerdo con el sistema de clasificación biofarmacéutica, a través de sus propiedades de solubilización.
A prototype of a low-cost eyelid cleaning foaming solution for symptom management in patients with chronic blepharitis: An I-optimal mixture experimental design
Authors: Burgos-Flórez Francisco Javier , De las Salas Roxana
Published: February 2020

lepharitis is a common chronic eye condition that causes eyelid inflammation, leading to inflamed, irritated, sticky and itchy eyelids and flaking of the skin. For its treatment, patients often need indefinite use of an eyelid cleaning solution which usually cost more than 20 USD per 80 ml bottle and lasts, on average, one month. For those patients unable to afford the treatment, physicians recommend the use of a do it yourself (DIY) solution. However, the efficacy of DIY eyelid solutions might fluctuate according to the type of blepharitis present in the patient and inadequate pH stabilization of the solution might promote additional itchiness, irritation, and dryness of the skin and eyes. Thus, we propose an optimized DIY solution prototype for symptom management in patients with chronic blepharitis. The formulation contains a significant ratio of tea tree oil and resulted in suitable pH and foam expansion values. The low cost and ease of preparation of the designed formulation make it an affordable, effective alternative in the treatment of chronic blepharitis.

La obtención de complejos polielectrolito entre el polímero catiónico Eudragit® E100 y moléculas aniónicas, con neutralización adicional de un ácido inorgánico, ha sido una práctica recurrente en el área de investigación de estos sistemas de liberación controlada. En el presente trabajo se buscó estudiar el efecto de la adición del ácido fuerte en el polímero, para ello se llevó a cabo la obtención por evaporación de solvente de diez complejos (de diferente composición entre Eudragit® E100 y ácido benzoico o ácido clorhídrico) y de cuatro ionómeros (sin el activo), a los cuales se les realizó análisis por FTIR y DSC.Los resultados demostraron la obtención de los respectivos complejos polielectrolito y de los ionómeros; además los espectros de FTIR revelaron la relación directa entre la reacción de hidrólisis de los grupos ésteres del polímero y la proporción de HCl adicionada. Los termogramas, por su parte, evidenciaron la existencia de una reacción en el polielectrolito (PE), la cual se favoreció en aquellas composiciones en las que el proceso de hidrólisis ocurrió en mayor magnitud. El proceso de hidrólisis que se describe en el presente estudio debe tenerse en consideración en las futuras investigaciones en el campo, ya que su ocurrencia podría tener implicaciones en las diversas variables que se evalúan en este tipo de sistemas.

Students’ response to a Massage & Meditation medical school course elective
Authors: Binstock Maxwell , Morinis Leora , Adler Shelley , Mehling Wolf E.
Published: February 2020

This article was migrated. The article was marked as recommended. Objectives: Due to high incidence of medical student and physician burnout, medical education needs to include skills for life-work balance. Patients complain that clinicians depend on technology during clinic visits, and use less touch. To address this educational need, we designed an 18-hour curriculum that combines massage (to reduce anxiety and teach skillful touch) and meditation (for burnout prevention). We explored whether learning basics of massage and meditation could give medical students tools for self-care and skillful touch. Methods: The curriculum was implemented as an elective at the Medical School since 14 years. We collected 181 anonymous student evaluations and conducted pre-post surveys to evaluate the curriculum. We assess mindful bodily awareness (by Multidimensional Assessment of Interoceptive Awareness questionnaire) and conducted thematic analysis of students' comments. Results: Students appeared highly satisfied with the class (4.94 [Range 1-5]) and reported confidence in being able to apply massage and meditation in their personal and professional life. They commented on the importance of skillful touch and gained more confidence in using touch in clinical care. The pre-post survey showed improvements in interoceptive bodily awareness. Students felt that they developed new skills for self-care and stress management, experienced a sense of community among peers, and stated that the class provided necessary teaching complementary to the mandatory medical school curriculum. Conclusions: A course of Meditation and Massage may be a valuable complementary elective to medical school education, supporting self-care and stress management in preparation for a demanding profession, and may improve palpatory examination skills.
The Integration of Health and Education Services: the power of COAPES for Medical Education
Authors: Zarpelon Luis Fernando , Terencio Maria Leandra , Alves Batista Nildo
Published: February 2020

This article was migrated. The article was not marked as recommended. The 2014 National Curricular Guidelines (DCN), which indicate the integration between education and services as a critical path in professional training, imputed to schools some curricular reforms aimed at early and effective introduction of students into the SUS health care network, which meant a fundamental advance in the educational process. Several teaching-service integration experiences have promoted advances in the approximation between universities and health services. However, the level of integration required between public health care and human resources training policies, both highly complex internal systems, entails new challenges to the establishment of management tools capable of sustaining this process. Therefore, this work mainly aims to share our experience with a medical school in the Education-Health Public Action Organizational Contract (COAPES) and the potential of this process for the medical course of the Federal University of Latin American Integration (UNILA). To date, this experience has resulted in significant gains in the development of curricular educational activities, such as establishing learning objectives based on local reality, opening the entire care network in the region covered from school to teaching, advancing the placement of the students with relevant attributions in the service chain and the approach with the other health IES that are part of the contract, enabling the development of collaborative skills of future physicians with other health professionals, empowering them to collaborative practice. Some constraints must be satisfied so that this process effectively serves the construction and maintenance of the national health system, such as revision of the school calendar, the involvement of teachers in care and management processes and the construction of instruments that explicit rules and represent clear agreements that support these inter-organizational relationships resulting from the unification of actions and public services in a single system, to be executed by many political and autonomous entities.
Effect of Mitosis on the Resistance to Oxidative and Osmotic Stresses in Yeast
Authors: ATALAY Pinar Buket , KALUC Nur , CAVUSOGLU Elif Ergin
Published: February 2020

Cancer
cells are defined by abnormal and unrestricted mitotic divisions, therefore
targeting mitosis is a useful strategy for cancer treatment. Two groups of
drugs that are most successfully used in the treatment of several types of
cancer, taxanes and vinca
alkaloids, exhibit their anti-tumor effects by causing a mitotic arrest.
However, not much is known about whether being arrested in mitosis affects the
sensitivity of cells to tumor-related stresses, such as oxidative and osmotic
stresses. In this study, we investigated whether mitosis affects the
sensitivity of Saccharomyces cerevisiae
cells to H2O2-induced oxidative stress and
sorbitol-induced osmotic stress. Mitotic and G1-arrests were induced by
nocodazole and alpha factor, respectively. The effects of nocodazole or alpha
factor treatments on the sensitivity of wild type (WT) and MAD3 deletion (mad3Δ) strains to
oxidative stress and osmotic stress were evaluated by the spotting and coloni
forming unit (cfu) assays as well as detection of reactive oxygen species (ROS)
production. Data were
analyzed using Student’s t-test and expressed as standard deviation (std), p<0.05 was considered significant. Our data indicate that mitosis
significantly increases resistance to oxidative stress, however it
does not have any significant effect on the osmotic stress resistance in yeast.
Full Order Symbolic Small Signal Analysis of Peak-Current-Controlled SEPIC by PWM-Switch Model
Authors: CENGELCİ Ekrem
Published: February 2020

Full order small signal analysis of peak-current controlled non-isolated
Single Ended Primary Inductor Converter (SEPIC) is presented by utilizing
pwm-switch model in Continuous Conduction Mode (CCM). The analysis provides
control to output voltage transfer function together with its zeros and poles
in symbolic form taking into account parasitic resistances of all four reactive
components in the SEPIC topology. The resultant transfer function is with 4th
order numerator and 5th order denominator, which necessitates approximation in
deriving formulas of zeros and poles in symbolic form. Symbolically derived
transfer function of the SEPIC is validated on two different numerical
examples, one with operating in step down mode and another operating in step up
mode, by frequency domain PSpice simulations on average circuit models and by
time domain LTspice simulations on switching models. The mathematical analysis,
PSpice and LTspice simulations, and measurement results of control to output
voltage transfer function of SEPIC agree very well proving that the symbolic
control to output voltage transfer function of SEPIC together with its zeros
and poles are successfully derived.

requirements of feature extracting, advanced pre-processing, a variety of
parameters obtained from satellites and other type of images, and analyzing of
images. The dissimilarity of results, enhanced dataset requirement, intricacy
of the problem domain, general use of Synthetic Aperture Radar (SAR) images and
problems on generalizability are some topics of the issues related to ship
target detection. In this study, we propose a deep convolutional neural network
model for detecting the ships using the satellite images as inputs.  Our model has acquired an adequate accuracy
value by just using a pre-processed satellite image input. Visual and graphical
results of features at various layers and deconvolutions are also demonstrated
for a better understanding of the basic process.

Authors: ELMAS Bahadır , AKKAYA ARIER Ümit Özlem
Published: February 2020

Calculation of spectral transmittance and reflectance values of a
multilayer coating need to be known the spectral refractive index and the
extinction coefficient values. In order to calculate the spectral optical
indices a software was developed. It uses the spectrophotometric transmittance
and reflectance values of single layer coatings, each coated only with the
material in question, and the thicknesses of these layers.  Considering the effective functions it
contains, the software was written in the Matlab programming environment.

Authors: GÜNER Sait Barış
Published: February 2020

We investigated the microstructure and magnetic
properties of Gd123:Gd211 = 1-y : y (y = 0.0, 0.1, 0.2, 0.3, 0.4 and 0.5) bulk
superconductors with the diameter of 13 mm and thickness of 5 mm fabricated by
melt-textured method.  The vertical
levitation force between melt-textured bulk superconductors and a permanent magnet
is measured at 30, 40, 50, 60, and 77 K under zero-field-cooling (ZFC) and
field-cooling (FC) regimes by Magnetic Levitation Force Measurement System
(MLFMS). The phase and microstructures properties of all samples are determined
by SEM (Scanning Electron Microscope). The measurements of superconducting
characteristics showed that the maximum vertical levitation forces of the Gd01
sample were noted as 3.04, 2.30, 1.53, 0.91 and 0.16 N at the temperatures of
30, 40, 50, 60 and 77 K, respectively. The present results perform that a
high-performance good-quality GdBCO can improve from laboratory conditions to
technological applications for large scale levitated system.

Authors: SELENGİL Uğur , BEKTAŞ Tijen Ennil
Published: February 2020

In this study, unexpended perlite waste obtained from a
factory producing expanded perlite was used as adsorbent. Malachite green (MY),
which is a cationic dyestuff, was used as adsorbed material. The pore properties including
the BET surface area, pore volume and average pore diameter were characterized. The
chemical composition of the perlite was analysed by XRF.  The effects of initial pH,
the amount of adsorbent, contact time and initial dyestuff concentration were
examined. The adsorption kinetics of dyestuff obeys the pseudo second-order kinetic model. The experimental data indicated that the
adsorption isotherms are well described by the Langmuir isotherm equation. 99% dyestuff removal
was obtained under optimum conditions. As a result, it was found that
perlite waste was a suitable adsorbent for malachite green dyestuff.

Published: February 2020

RESUMO: O presente estudo tem como foco analisar como crianças em fase de aquisição do sistema verbal irregular do PB (Português Brasileiro) aplicam os processos fonológicos consonantais diante de conjugações verbais irregulares e qual a relação desses processos com a aquisição verbal do português. Para isso, selecionou-se o total de nove verbos, que foram avaliados segundo a aplicação de um instrumento, criado especificamente para esta pesquisa. Participaram da coleta de dados 16 crianças, falantes nativas de PB, estudantes de 1º ao 4º ano, na faixa etária de 06 a 09 anos de idade, todos alfabetizados. A partir das possibilidades de análise, entende-se que a aquisição do sistema verbal irregular do PB pode ser considerada como tardia, motivada, especialmente, pela presença de alternâncias consonantais nos radicais de suas flexões, as quais operam na língua com processos fonológicos consonantais.
UMA ANÁLISE QUANTITATIVA E QUALITATIVA DA SUPERESTRUTURA NARRATIVA NO DECLÍNIO COGNITIVO LEVE E NA DOENÇA DE ALZHEIMER
Authors: Jerônimo Gislaine Machado , Hübner Lilian Cristine
Published: February 2020

Narrativas orais fazem parte do cotidiano da população idosa. Desse modo, torna-se relevante analisar como idosos em um processo de envelhecimento típico e atípico constroem suas histórias. Participaram deste estudo 64 idosos com baixa escolaridade, divididos em três grupos: idosos neurologicamente saudáveis, idosos com Comprometimento Cognitivo Leve e idosos com Doença de Alzheimer leve. Foi realizada testagem da memória de trabalho, assim como uma avaliação linguística da produção de narrativa oral, baseada em instrumento pictórico com sete figuras (The Dog Story, Le Boeuf, 1976; Hübner et al., 2019). Para avaliação da superestrutura narrativa foi utilizado o Modelo de Adam (1987, 2008). Os resultados mostraram diferença significativa entre os grupos clínicos e o grupo controle tanto na criação da superestrutura da história quanto no desempenho do teste de memória de trabalho. Houve uma correlação positiva entre o desempenho da memória trabalho e o desempenho na construção da narrativa, evidenciando, assim, uma relação estreita entre ambos os componentes da cognição.

Comparing the factors of safety from finite element and limit equilibrium analyses in lateral support design
Authors: Potgieter J , Jacobsz S
Published: February 2020

Soil-nails and anchors as means of lateral support in surface excavations require stability analyses as part of design. Generally, the acceptance criterion is some arbitrary 'factor of safety' which can be routinely computed using well-established principles of limit equilibrium analyses. These methods have been tested over many years and have been shown to be adequate for design. There is an increasing trend towards the use of the finite element strength reduction methods to determine factors of safety in lateral support design. Differences are often reported between factors of safety calculated using these methods. There is also a danger that engineers might use finite element modelling without full appreciation of the impact of choices and assumptions made in using the software. This paper compares the results of limit equilibrium and finite element calculations to assess factors of safety. Under certain conditions the factor of safety from the finite element strength reduction technique is comparable with limit equilibrium methods, provided that the same failure mechanism is evaluated. In addition, in the case of anchors, the same capacity must be specified in both analyses. In defining in-situ stress states, the friction angle and Poisson's ratio should be specified so as to not violate the yield criterion. Modelling parameters (mesh grading and boundary distances) were found to have relatively minor influences on the factor of safety for the strength reduction technique.
Concrete properties for ultra-thin continuously reinforced concrete pavements (UTCRCP)
Authors: Mackellar A , Kearsley E
Published: February 2020

Ultra-Thin Continuously Reinforced Concrete Pavement (UTCRCP) is an innovative road paving technology that can have significant advantages over traditional road paving techniques. Tests have shown that UTCRCP can carry in excess of one hundred million E80s (standard 80 kN axle loads). The laboratory tests used for quality control of conventional concrete are not adequate to fully capture the effects of the steel fibres added to the high strength concrete used in UTCRCP. In this study the concrete strength and fibre content were varied and the mechanical and physical properties of the concrete were measured. The tests included compressive strength, split cylinder, modulus of elasticity and four-point bending slab tests. The results of these tests are reported in this paper, and the suitability and shortcomings of the tests are discussed.
Análisis crítico sobre el uso del SROI en la evaluación del impacto social en iniciativas de emprendimiento social: caso México
Authors: Valdés Medina Filiberto Enrique
Published: February 2020

La incapacidad del Estado para atender problemáticas sociales como la pobreza en todas sus gamas, el desempleo, y el difícil acceso a la educación y a los servicios de salud, por mencionar solo algunas, ha llevado a la institucionalización del sector social en México, lo que implica un incremento de iniciativas de emprendimiento social dentro del ecosistema emprendedor. Por ello, la necesidad de analizar y valorar las técnicas de evaluación financiera de iniciativas de esta naturaleza es de gran importancia, para determinar si el emprendimiento social realmente está dando solución a la problemática social. En la presente investigación se contempla y conceptualiza el emprendimiento social, haciendo énfasis en la empresa social, a la vez que se indaga sobre su desarrollo en México, para posteriormente abordar las áreas de oportunidad del uso del retorno social de la inversión (SROI, social return on investment) como una medida con una fuerte vocación financiera en la gestión de iniciativas de emprendimiento social.
Small and Medium Enterprises in the Americas, Effect of Disaster Experience on Readiness Capabilities
Authors: Sarmiento Juan Pablo , Sarmiento Catalina , Hoberman Gabriela , Jerath Meenakshi , Sandoval Vicente
Published: February 2020

Disaster risk reduction (DRR) is key in strengthening resilience and achievement of sustainable development. The private sector is co-responsible for DRR: it is a generator of risks, and a subject exposed to risks. There are competing narratives in the literature regarding the relationship between business’ disaster experience and DRR. The current study defined and characterized businesses in the Americas, with a particular interest in small and medium enterprises, and examined whether disaster experience predicts DRR, considering business size. Secondary data analyses were conducted using data from a previous study on private sector participation in DRR conducted in six Western Hemisphere cities (N=1162): Bogotá, Colombia; Kingston, Jamaica; Miami, USA; San José, Costa Rica; Santiago, Chile; and Vancouver, Canada. Results confirmed that business size matters – small businesses had lower levels of DRR efforts compared to medium and large businesses. Disaster experience (i.e., supply chain disruption, loss of telecommunications, power outage, and damaged facilities) predicted DRR. The findings underscore the importance of fostering, advising, and financing small and medium enterprises to proactively develop capabilities in the line of risk and emergency management, and early resumption of operations, post-disasters. Governing agencies and civil society organizations have the ability to provide this support.
