Perspectivas da alfabetização e letramento científico no Brasil: levantamento bibliométrico e opinião de profissionais da educação do ensino fundamental I
Authors: Gomes Vanessa , Santos Amilton Cesar
Published: June 2018

Alfabetização científica (AC) constitui a capacidade de compreender, utilizar e refletir sobre um tema, utilizando a linguagem científica. Letramento científico (LC) se relaciona com a função e prática social utilizando o conhecimento científico. Estes temas têm ganhado relevância devido aos avanços científicos e tecnológicos da sociedade atual. O objetivo deste trabalho foi realizar um levantamento bibliométrico buscando pesquisadores brasileiros, os quais se dedicam aos estudos sobre AC/LC no Ensino Fundamental I (EFI). E, em seguida, realizar um levantamento da percepção de profissionais da educação sobre temas envolvendo AC/LC e metodologias e ferramentas envolvidas no ensino das Ciências Naturais no EFI. O levantamento bibliométrico foi realizado na plataforma Scielo.br. A percepção dos profissionais da educação (diretoras, coordenadoras pedagógicas e docentes) sobre AC/LC no EFI foi levantada por meio de questionários de múltipla escolha. Através do levantamento bibliométrico foram identificados 23 artigos (seis com foco no EFI) utilizando as palavras chave alfabetização científica. Utilizando as palavras alfabetização científica e letramento identificou-se oito artigos e como as palavras letramento científico identificou-se quatro artigos, sendo que, nas duas buscas não foram identificados artigos com foco no EFI. Resumidamente, a segunda parte da pesquisa revelou o apoio e reconhecimento sobre a necessidade de programas eficazes envolvendo AC/LC no EFI e a necessidade em se propor metodologias inovadoras de ensino em Ciências Naturais reforçada pela capacitação dos docentes. Nenhuma das escolas analisadas possuía laboratório e a maioria das docentes assumiu que, os cursos de graduação não capacitam os professores a atuar com metodologias experimentais no ensino de Ciências no EFI.

Published: June 2018

Material degradation within taper junctions of modular total hip replacements remains of great concern. Imprinting and column damage are two damage modes that frequently occur on head taper surfaces. Both can cover large areas and therefore can be associated with significant material loss. It was the purpose of this study to determine the prevalence of imprinting and column damage on a group of retrievals collected at our medical center and to identify damage pathways on selected cases. We asked two research questions: (1) How do CoCrMo stems imprint into CoCrMo heads? (2) Does alloy microstructure influence the column damage pattern in CoCrMo heads? In order to answer these questions, we conducted a retrieval study on moderately to severely worn femoral head taper surfaces that were paired with stems of different materials. All components were viewed under a stereo-light microscope to determine the presence of imprinting and column damage. Selected cases were further studied by means of scanning electron microscope, interferometry, and metallography to determine damage mode and the potential role of alloy microstructure. Our results demonstrated that imprinting is independent of the stem material but highly dependent on its topography. The imprinting process is at least initially driven by fretting and the generation of oxide particles. Column damage on the other hand is highly dependent on the microstructure of wrought CoCrMo alloys, which can exhibit banding resulting from slight alloy segregations that were characterized by molybdenum depletion. Therefore, column damage may be prevented by avoiding banding of the alloy during the thermomechanical processing. This study demonstrates that it is important to consider differences among the occurring degradation mechanisms and to understand how they relate to material and design factors.
Lessons Learned from Retrieved Total Elbow Implants
Authors: Wright Timothy M. , Lo Darrick , Lipman Joseph , Figgie Mark , Hotchkiss Robert
Published: June 2018

Total elbow replacement is a viable option for joint reconstruction as treatment for arthritis or severe fractures, though the clinical results are inferior to those achieved in hip and knee replacement. Few studies have been performed analyzing retrieved total elbow components, and those few have concentrated on explaining failure modes. In our work, we have applied retrieval analysis to the gold standard design of elbow replacement, the Coonrad-Morrey, using the results to determine the primary loading modes and to quantify the deformation in the polyethylene bushings. Finite element analyses were then used to replicate the loading and deformation observed on the retrievals. Finally, a novel design approach was proposed, one that will enhance the wear and deformation of the polyethylene bearing and constraint surfaces while also enhancing the creation of internal moments at the joint to help resist the externally applied varus moments that are the dominant mechanical burden during activities of daily living. As this design hopefully reaches clinical use, future retrieval studies will help validate the design approach, thus completing the design cycle.
Medical Device Regulation and Retrieval Analysis
Authors: Ochoa Jorge A. , Siskey Ryan L. , Kuehn Carrie M. , Ciccarelli Lauren
Published: June 2018

Retrieving and analyzing medical devices from revision or removal surgeries are critical activities for understanding device failures. However, the role of retrieval analysis should not be limited to the investigation of individual failures and subsequent root cause analysis. Implementation of retrieval programs that operate throughout the commercial life of devices can be a means by which manufacturers inform product development, augment regulatory submissions, evaluate and mitigate risks, implement continuous improvement, and develop new designs or product enhancements. Understanding how retrieval analysis can contribute to the Total Product Life Cycle of a device will enhance a manufacturer’s ability to address regulatory requirements and U.S. Food and Drug Administration inquiries, identify and respond to unanticipated failure modes, evaluate successful in vivo performance of its devices, and to improve the quality, safety, effectiveness, and performance of new devices. We will review some of the basic scientific and regulatory requirements that apply to devices in the context of retrievals. We will also examine the role of retrieval analysis during device development within the design control framework and will provide guidelines for implementing a formal program that will allow manufacturers to realize the benefits of retrieval analysis throughout the Total Product Life Cycle of a medical device.
Genetic Links to Total Joint Arthroplasty Outcomes: A Systematic Review
Authors: Perkins Meredith , Butler Reed , Tidwell Lucas , Gu Weikuan , Mihalko William M.
Published: June 2018

Total hip and knee arthroplasties are some of the most common surgical procedures in the United States. While the majority of patients experience successful outcomes, there still remain a large number that undergo revision surgeries due to loosening of the implant, often secondary to septic or aseptic osteolysis. In this study, we sought to perform a comprehensive literature review to investigate underlying genetic causes that may predispose a patient to prosthesis failure. The following single nucleotide polymorphisms (SNPs) were found to have a statistically significant association with aseptic loosening: OPG-163A allele and A/A genotype, RANK+575T allele and T/T genotype, MBL-550 C allele and C/C genotype, MBL-550 G allele and G/G genotype, TNF-238A allele, TGF-β1 (29T→C) T/T genotype, MMPI-1 (rs5854) C allele, and C/C genotype and MMP-1 2G allele. Additionally, the IL-6 (-174G/-572G/-597A) haplotype was associated with a significant increase in osteolysis. A negative correlation with aseptic loosening was observed for SNPs of the IL-1Ra (rs5854) C allele and IL-2. SNPs that correlated with PJI/septic loosening were OPG-163A allele and A/A genotype, MBL-550 C allele and C/C genotype, MBL+54 G/G genotype, TLR9-1486 T/C, and C/C genotypes, IL1β-511T allele. The current understanding of both septic and aseptic periprosthetic osteolysis describes the process as predominantly inflammatory in origin and leading to enhanced osteoclast activity. As such, these studies sought to focus on SNPs located on genes encoding cytokines and receptors involved in the inflammatory process and in osteoclast differentiation. While the number of studies, sample size, and demographics are limiting factors, the results provide significant data indicating that an individual's genetics play a much more integral role in TJA outcomes than previously thought. We advocate for future studies to investigate further the influence of genetics on implant failures.
Increased Axonal Bouton Stability during Learning in the Mouse Model of MECP2 Duplication Syndrome
Authors: Ash Ryan T. , Fahey Paul G. , Park Jiyoung , Zoghbi Huda Y. , Smirnakis Stelios M.
Published: June 2018

MECP2duplication syndrome is an X-linked form of syndromic autism caused by genomic duplication of the region encoding methyl-CpG-binding protein 2 (MECP2). Mice overexpressingMECP2demonstrate social impairment, behavioral inflexibility, and altered patterns of learning and memory. Previous work showed abnormally increased stability of dendritic spines formed during motor training in the apical tuft of primary motor cortex (area M1) corticospinal neurons in the MECP2 duplication mouse model. In the current study, we measure the structural plasticity of axonal boutons in layer 5 pyramidal neuron projections to layer 1 of area M1 during motor training. In wild-type littermate control mice, we find that during rotarod training the bouton formation rate changes minimally, if at all, while the bouton elimination rate more than doubles. Notably, the observed upregulation in bouton elimination with training is absent inMECP2duplication mice. This result provides further evidence of an imbalance between structural stability and plasticity in this form of syndromic autism. Furthermore, the observation that axonal bouton elimination more than doubles with motor training in wild-type animals contrasts with the increase of dendritic spine consolidation observed in corticospinal neurons at the same layer. This dissociation suggests that different area M1 microcircuits may manifest different patterns of structural synaptic plasticity during motor training.

Authors: Graham Karen , Camille Rhonda , Bonneau Tracey Kim
Published: June 2018

A unique Indigenous-focused Art Expo on the topic of breastfeeding was held at En’owkin Centre at Penticton Indian Band in October and November 2017. The En’owkin Centre is a nationally recognized Indigenous arts and training centre. This review highlights some of the art from the En’owkin Indigenous Expo including six of the Community Art Projects and three Independent Art pieces.   

The En’owkin Breastfeeding Art Expo was part of a larger Expo (2017-2018) that is a joint partnership with Interior Health and the non-profit social service organization KCR-Community Resources; it was funded by five organizations. With 35 community partners, the project was led by a ten-member steering committee that including two Indigenous members. The Expo offered a full-colour Art Catalogue and a Teacher’s Guide. The larger Expo travelled to six locations in the Interior of British Columbia, and included 15 large community art projects and 65 independent artworks by citizens of central British Columbia, as well as 20 short videos that tell the significant art and health stories.  

Art is recognized as an important tool for Indigenous people for health and healing. This Expo was an opportunity to celebrate community, art, and breastfeeding. The goals of the Expo were multi-faceted, namely, to increase awareness of the benefits of breastfeeding, to encourage new ways of thinking about health through art, and to support work towards establishing better care for women to breastfeed in the hospital and community.

Published: June 2018

Abstract This controlled randomized clinical trial evaluated the effect of associating at-home and in-office bleaching procedures on tooth sensitivity (TS) and bleaching effectiveness. Forty patients subjected to on session of in-office bleaching with 38% peroxide hydrogen. Subsequently, the patients were randomly allocated to receive a second session of in-office bleaching or to use a tray containing 10% carbamide peroxide delivered during 7 consecutive days. The worst TS score reported during or after each bleaching procedure was recorded using a verbal rating scale and TS risk (score different from 0) was calculated. Color changes were measured 7 days after each in-office session (for patients receiving in-office procedures only) or after the end of at-home bleaching (for the combined protocol), and 6 months after the last procedure for both bleaching protocols. Color was assessed by a spectrophotometer and by color match with the Vita Classical and Bleach guide scales. Statistical analyses were carried out to assess possible differences between the protocols regarding the outcomes and to analyze the effect of time of assessment on color changes. The bleaching protocol did not affect the risk for and the maximum level of TS reported, irrespective of the time of assessment. In the color evaluation, the bleaching protocol also did not affect the ultimate tooth color. In conclusion, after one in-office bleaching session, there was no difference in bleaching effectiveness and TS between performing a second in-office session and associating it with 1-week at-home bleaching.

Published: June 2018

Abstract This study aimed to evaluate the effect on oral health-related quality of life (OHRQoL) of two treatment protocols for dental fluorosis in individuals enrolled in a randomized clinical trial. Seventy volunteers, who lived in a fluorosis endemic area in Brazil, and had at least four maxillary anterior teeth showing fluorosis with a Thylstrup and Fejerskov index from 1 to 7, were randomized into two treatment groups (n= 35): GI- enamel microabrasion; or GII- microabrasion associated with at-home bleaching. Microabrasion was performed using 37% phosphoric acid and pumice, and at-home tooth bleaching with 10% carbamide peroxide in a tray. Volunteers completed a questionnaire at baseline and 1-month post treatment to assess changes in OHRQoL, using the Oral Impact on Daily Performance (OIDP). Differences in overall impact scores between and within treatment groups were analyzed with Wilcoxon (within) and Mann-Whitney (between) tests. Changes in performance scores were analyzed using Wilcoxon tests (a< 0.05). One month after treatment, subjects reported improvement in OHRQoL. Both groups showed lower OIDP scores (p< 0.001), but there was no difference between them. Eating, cleaning teeth, smiling and emotional state performance scores were lower after treatment for the whole sample. In conclusion, the treatment with microabrasion improved the OHRQoL in this sample of individuals living in a fluorosis endemic area regardless of the addition of at-home bleaching.

Published: June 2018

The phenolic compounds and radical scavenging activity of ethanolic extracts of five adzuki beans were evaluate according to cultivar. The predominant phenolic acids in five cultivars of adzuki bean were (+)-catechin and gallic acid. Antioxidant capacities were determined using 2,2-diphenyl-1-picrylhydrazyl and 2,2-azinobis (3-ethylbenothiazoline-6-sulphonic acid) diammonium salt, and reducing power was positively enhanced according to the total polyphenolic content. In a cell-based assay, adzuki beans showed cytoprotective effects against oxidative stress induced by tert-butyl hydroperoxide and inhibitory effects on the production of reactive oxygen species, except for the cultivar Vigna angularis var. nipponensis cv. Whinnarae. In conclusion, (+)-catechin was the predominant phenolic compound found in adzuki beans, but there were differences according to the cultivar. Overall, the adzuki bean cultivars showed different antioxidant activities and cytoprotective effects according to the concentration and composition of phenolic compounds.

Proposing an Expanded Measure for Comparing Online/Hybrid to Face-to-face Courses
Authors: Blau Gary , Jarrell Sherry , Seeton Anthony , Young Tim , Grace Kelly , Hughes Michael
Published: June 2018

Online education continues to increase. With increased online offerings, it is important to evaluate the integrity or equivalence of online/hybrid courses relative to face-to-face (F2F) courses. This study used three separate samples of business undergraduates taking both online/hybrid and F2F courses in the same semester (i.e., mixed course delivery format), across summer, fall and spring semesters. Eight items were used to assess students’ perceived favorability of online courses (PFoOC) compared to F2F courses. Across all three samples, two related but distinct sources for course comparison consistently emerged, instructor-related and peer related. An eight-item measure represents a necessary improvement over a previously developed four-item PFoOC measure, because it allows for additional relevant item comparisons between online/hybrid versus F2F courses. It is hoped that this measure can be used to further research evaluating online education.

Na busca de sementes e plantas de alto padrão de qualidade, a utilização do silício pode ser interessante na agricultura, pois pode incrementar a produtividade, regular a perda de água, melhorar a taxa fotossintética,aumentar a rigidez da estrutura dos tecidos entre outros. Dessa forma, objetivou-se com essa pesquisa verificar o efeito da aplicação foliar de silício no crescimento, fisiologia de plantas de trigo e na qualidade de sementes de trigo produzidas. Empregou-se o delineamento experimental em blocos casualizados com fatorial 2x4 com 5 repetições, onde os tratamentos foram compostos por duas cultivares de trigo (BR18 e BRS254) e quatro dosagens da formulação comercial Supa Sílica da marca Agrichem®: 0,0 L ha-1, 0,5 L ha-1, 1 L ha-1 e 2,0 Lha-1, divididas em três aplicações nos estádios de perfilhamento, emborrachamento e floração. Foram feitas avaliações fisiológicas e filotécnicas como fluorescência da clorofila, taxa de transporte de elétrons, diâmetro, altura, massa seca, número de perfilhos e fitoxidade. A qualidade fisiológica das sementes foi avaliada pelosseguintes testes: germinação, primeira contagem, índice de velocidade de germinação, emergência, estande inicial. A cultivar BR18 produziu maior quantidade de perfilhos, massa seca, clorofilas A, B e total e de Fv/Fm do que a cultivar BR254 com aplicação foliar de silício. A taxa de transporte de elétrons, fluorescência inicial e a fitotoxicidade forma influenciadas negativamente pelo aumento das doses de silício foliar para ambas as cultivares. A aplicação de silício foliar não interfere na qualidade das sementes de trigo, porém melhorou o desempenho de emergência, estande inicial e IVE da cultivar BR18.
Behavior of bentonite in an aqueous electrolytic solution – evaluation of electrolytic aggregation for adsorption capacity of Cd2+ ions onto bentonite
Authors: Dilrukshi Ekanayaka Achchillage Ayesha , Fujino Takeshi , Motegi Shun
Published: June 2018

In this study, we used aqueous solutions containing 1 mg/L of Cd2+ for electrolysis while varying the current density (CD), amount of bentonite added and the effective submerged area to investigate the adsorption capacity of Cd2+ ions onto bentonite by electrolytic aggregation. The adsorption of Cd2+ ions increased with increasing amount of bentonite added to the electrolytic solution. The addition of bentonite also regulated the pH of the electrolytic solution during the electrolysis process in addition to the hydrolysis of water. The maximum adsorption capacities at equilibrium (qe) for current densities of 3.14 and 7.49 mA/cm2 (i.e. for 2 and 1 L electrolytic solutions) with 0.2 g of bentonite were 4.54 and 2.92 mg/g, respectively. The removal of Cd2+ (RCd) clearly depended on the pH of the electrolytic solution. Moreover, qe decreased with increasing amount of bentonite used for electrolytic aggregation. The findings of this study will be useful for understanding the aggregation of clay particles under electrolysis and their adsorption behaviors.

Segundo a teoria dos stockholders, as empresas devem gerar o maior valor para seus acionistas. Por outro lado, a teoria dos stakeholders, aliada à responsabilidade social corporativa, pressupõe que a gestão empresarial deve destinar recursos para seus stakeholders, como forma estratégica de eficiência e maximização do resultado empresarial. Tendo em vista o choque destes pressupostos, o objetivo foi verificar se os gastos sociais internos, evidenciados conforme a NBC T 15, afetam o desempenho das empresas do ISE. A amostra contemplou 22 empresas que participaram do Índice de Sustentabilidade Empresarial no período de 2010 a 2015, totalizando 102 observações. Metodologicamente, utilizou-se regressão por mínimos quadrados ordinários, com dados em painel com efeitos aleatórios. Os principais resultados indicaram não haver relação estatística entre os gastos sociais internos, seja de forma direta ou indireta, e o desempenho operacional das empresas, mensurado pelo ROA. Deste modo, os resultados obtidos estão em convergência com os pressupostos da teoria do stockholders, no qual a premissa central é a maximização do valor da empresa para o acionista. Com isso, o pagamento de benefícios aos colaboradores acima dos parâmetros legais não são aconselháveis à gestão, pois não influenciam o desempenho das empresas. Deste modo, os resultados deste trabalho contribuem para a área de contabilidade e gestão das empresas nas decisões e na estratégia adequada para alocação de recursos, seja de forma direta ou indireta para seus colaboradores.Palavras-chave: Teoria dos stakeholders.

Se analizó la dinámica del elemento arbóreo de bosques naturales de segundo crecimiento de Pinus en el noreste de México. Para ello, a partir de datos previos a las intervenciones silvícolas, se evaluó el comportamiento de diferentes parámetros dasométricos relacionados con la densidad y las dimensiones del arbolado. Se utilizaron registros de todos los individuos con diámetro a la altura del pecho mayor o igual a 7.6 cm, provenientes de tres monitoreos periódicos (años 1986, 1996 y 2006) de parcelas permanentes. A las variables dasométricas se les realizaron pruebas de comparación de medias entre evaluaciones. Las diferencias en dimensiones de los parámetros, en evaluaciones sucesivas, resaltan la dinámica de crecimiento y desarrollo propia de masas regulares. El crecimiento de árboles promedio y parcelas mostró un incremento individual mayor en el primer periodo, que se mantuvo a nivel bosque en el último periodo, lo que sugiere un rendimiento continuo, producto de un sistema de manejo forestal sustentable. En conclusión, el bosque es regular, registra un incremento en las dimensiones del arbolado y el volumen de la masa, y permite sostener la producción maderable con las intervenciones silvícolas aplicadas para su desarrollo.
Halving the cost of quantum addition
Authors: Gidney Craig
Published: June 2018

We improve the number of T gates needed to perform an n-bit adder from 8n+O(1) to 4n+O(1). We do so via a "temporary logical-AND" construction which uses four T gates to store the logical-AND of two qubits into an ancilla and zero T gates to later erase the ancilla. This construction is equivalent to one by Jones, except that our framing makes it clear that the technique is far more widely applicable than previously realized. Temporary logical-ANDs can be applied to integer arithmetic, modular arithmetic, rotation synthesis, the quantum Fourier transform, Shor's algorithm, Grover oracles, and many other circuits. Because T gates dominate the cost of quantum computation based on the surface code, and temporary logical-ANDs are widely applicable, this represents a significant reduction in projected costs of quantum computation. In addition to our n-bit adder, we present an n-bit controlled adder circuit with T-count of 8n+O(1), a temporary adder that can be computed for the same cost as the normal adder but whose result can be kept until it is later uncomputed without using T gates, and discuss some other constructions whose T-count is improved by the temporary logical-AND.

Application of the MvdW1 and HVOS-NRTL mixing rules to the simultaneous correlation of excess enthalpies and W-shaped excess heat capacities data of 1,3-dioxolane + n-alkane systems
Authors: Djordjevic Bojan , Kijevcanin Mirjana , Tasic Aleksandar , Serbanovic Slobodan
Published: June 2018

The Peng-Robinson-Stryjek-Vera (PRSV) equation of state (EOS) coupled with a
modified two parameter van der Waals one-fluid mixing rule (MvdW1) and the
Huron-Vidal-Orbey-Sandler mixing rule incorporating the NRTL equation as a GE
model was used for the correlation of excess enthalpy (HE), excess heat
capacity (CpE) and the simultaneous correlation of both properties. All
calculations with temperature dependent parameters of EOS models were
applied to 1,3-dioxolane+n-alkane systems. The correlation of the H E and Cp
E data alone with four coefficients and the HE+CpE data with six
coefficients of the temperature dependent parameters of the HVOS-NRTL models
could be considered as very satisfactory.
Evaluation of maxillary buccal alveolar bone before and after orthodontic alignment without extractions: A cone beam computed tomographic study
Authors: Morais Juliana F. , Melsen Birte , de Freitas Karina M. S. , Castello Branco Nuria , Garib Daniela G. , Cattaneo Paolo M.
Published: June 2018

Objectives:

To assess the changes in the maxillary buccal alveolar bone during alignment without extractions. Secondarily, to evaluate the changes in arch dimensions and buccolingual inclinations of teeth and to identify risk factors for bone loss.

Materials and Methods:

Twenty-two adolescents with crowded permanent dentitions were treated without extractions with Damon 3MX brackets. Cone beam computed tomographic scans were taken before treatment (T0) and after alignment (T1). Bone thickness (BT) and height from the cementoenamel junction to the alveolar crest (BH) were evaluated at the maxillary central incisors, second premolars, and buccal roots of first molars. Changes in all variables from T0 to T1 were assessed. Correlations between bone changes and initial bone thickness, initial arch widths, initial crowding, amount of expansion, amount of tipping, and amount of molar rotation were calculated.

Results:

BT decreased and BH increased significantly for the incisors and mesiobuccal root of the first molars. Arch dimensions generally increased together with tipping. Bone loss was correlated with crowding and amount of expansion in the premolar region. Initially thinner BT was correlated with greater apical migration of bone for the incisors.

Conclusions:

Nonextraction alignment with self-ligating brackets led to arch expansion associated with tipping of teeth. Expansion related to alignment resulted in horizontal and vertical bone loss at the incisors and mesiobuccal root of the first molars. Thinner BTs and more severe crowding before treatment increased the risk for buccal bone loss.

Published: June 2018

Objectives:

To evaluate the skeletal, dental, and soft tissue changes after the use of miniscrew-anchored inverted Forsus fatigue-resistant device (FRD) in treatment of Class III malocclusion.

Materials and Methods:

In this controlled clinical trial, 16 patients (9 girls and 7 boys; age 12.45 ± 0.87 years) were consecutively treated with miniscrew-anchored inverted Forsus FRD. This group was compared with a matched control group of 16 untreated patients (8 girls and 8 boys; age 11.95 ± 1.04 years). Miniscrews were inserted bilaterally between the maxillary canine and first premolar. Forsus FRD was selected and inserted in an inverted manner mesial to the mandibular headgear tube and distal to the maxillary canine bracket.

Results:

Class I molar and canine relationships with positive overjet were achieved in an average period of 6.4 ± 1.46 months. Maxillary forward growth showed a statistically significant increase (SNA°: 1.73 ± 0.53, P < .5), maxillary incisor proclination was statistically significant (U1 to NA°: −0.39 ± 0.33, P > .5), and the lower incisors exhibited significant retroclination (L1 to NB°: 1.65 ± 0.83, P < .5). Significant lower lip retrusion and upper lip protrusion were obvious treatment outcomes (P < .5).

Conclusions:

The use of miniscrew-anchored inverted FRD could effectively increase maxillary forward growth, but it did not prevent mesial movement of the maxillary dentition. Significant lower incisor retroclination was observed. Significant esthetic improvement of the facial profile was achieved primarily because of lower lip retrusion and upper lip protrusion.

OBJECTIVE To determine the prevalence of dental anomalies in brachycephalic cats from various geographic regions and analyze potential relationships with oral disease.

DESIGN Prospective multicenter cross-sectional study.

ANIMALS 50 purebred Persian (n = 42) and Exotic (8) cats.

PROCEDURES Cats were anesthetized, and a complete dental examination, dental charting, 3-view oral photography, and full-mouth dental radiography were performed.

RESULTS Malocclusions were observed in 36 (72%) cats. Crowding of the teeth was evident in 28 (56%) cats, with the incisors being most commonly affected. Malpositioned teeth were noted in 32 (64%) cats, with abnormal orientation being the most common anomaly followed by rotation and impaction. Numerical abnormalities were present in 38 (76%) cats, including 6 (12%) with hyperdontia and 32 (64%) with hypodontia. Periodontal disease was reported in 44 (88%) cats, and cats with periodontal disease were older than cats without. Tooth resorption was evident in 35 (70%) cats. Overall, 123 of 1,349 (8.7%) teeth had external inflammatory resorption and 82 (6.1%) had external replacement resorption. The premolar teeth were the teeth most commonly affected with inflammatory resorption, whereas the canine teeth were the teeth most commonly affected with replacement resorption.

CONCLUSIONS AND CLINICAL RELEVANCE Results suggested that because of their brachycephaly, Persian and Exotic cats have unique oral and dental features that may predispose them to dental disease (eg, tooth resorption and periodontal disease). Knowledge of the particular dental anomalies common in brachycephalic cats could aid in early detection and mitigation of dental disease in these breeds.
A High-Throughput Screening Approach for the Optoelectronic Properties of Conjugated Polymers

Published: June 2018

We propose a general high-throughput virtual screening approach for the optical and electronic properties of conjugated polymers. This approach makes use of the recently developed xTB family of low-computational-cost density functional tight-binding methods from Grimme and co-workers, calibrated here to (TD-)DFT data computed for a representative diverse set of (co-)polymers. Parameters drawn from the resulting calibration using a linear model can then be applied to the xTB derived results for new polymers, thus generating near DFT-quality data with orders of magnitude reduction in computational cost. As a result, after an initial computational investment for calibration, this approach can be used to quickly and accurately screen on the order of thousands of polymers for target applications. We also demonstrate that the (opto)electronic properties of the conjugated polymers show only a very minor variation when considering different conformers and that the results of high-throughput screening are therefore expected to be relatively insensitive with respect to the conformer search methodology applied.

RECEPTION OF THE RUSSIAN LITERARY CLASSICS AT THE TURN OF THE XIX-XX CENTURIES: THE PROBLEM STATEMENT
Authors: Anisimova Evgeniya Evgen’evna
Published: June 2018

The article examines the features of literary reception of the classics in the Russian literature at the turn of the XIX-XX centuries. As it is shown in the paper, the temporal distance between the classics and modernity in the Russian literature, which is essential in the main European traditions, was compressed and turned into a sharply drawn and acutely problematized line. The act of self-consciousness of new culture was relevant not only to the “long-past” time of great aesthetic achievements, but also to the heritage and reputation of “living” classics, with whom modernists were in the state of intense dialogue.

Published: June 2018

This essay explores factors underlying the underutilization of Open Access (OA) to make education research literature freely available online, where it can benefit a global audience of researchers, students, teachers, and policymakers. Situating this autobiographical self-study in the context of the broader global and scholarly context, we use Bullough and Pinnegar’s (2001) setting-convocation-resolution approach to present our stories as points of departure for reflection, conversation, research, and action. We do so to raise awareness and enhance understanding of the complex and rapidly evolving legal, ethical, and practical issues surrounding public accessibility to scholarship. We also issue a call to action by outlining concrete, stakeholder-specific steps that would help OA become the new default for publication of education research.
An Electrocardiograph based Arrythmia Detection System
Authors: N Veena K , S. Shobha
Published: June 2018

Cardiac disorders turn out to be a serious disease if
not diagnosed and treated at the earliest. Arrhythmia is a
cardiac disorder that exists as a result of irregular heart beat
conditions. There are several variants in this type of disorder
which can be only diagnosed only when patient is under an
intensive care conditions and also the patient with such
disorder do not experience and physical symptoms. Such
diseases turn out to be deadly if not treated early. A detection
system is thus required which is capable of detecting these
arrhythmias in real time and aid in the diagnosis. An FPGA
based arrhythmia detection system is designed and
implemented here which can detect second degree AV block
type of arrhythmia. The designed system was simulated and
tested with ECG signal from MIT-BH database and the
results revealed that a robust arrhythmia detection system
was implemented.
