Abstract Introduction This cross-sectional study aimed to associate the normative cephalometric results of mandibular retrognathism treatment with patient perception on the esthetic improvement of facial profile. Objective this cross-sectional study aimed to associate the normative cephalometric results of mandibular retrognathism treatment with patient perception on the esthetic improvement of facial profile. Material and method The normative cephalometric results were obtained from lateral cephalometric radiographs of a sample of 24 Class II malocclusion patients in the pubertal growth spurt. Such patients were treated with a mandibular advancement device and evaluated by comparing pre- and post-treatment variables. The same radiographs were used to produce standardized black silhouettes that were randomly arranged. Patients were instructed to choose their preferred profile and indicate the changes perceived using a 7-point Likert scale. The data were compared with cephalometric results using a mixed-model methodology for time-repeated measures, Student’s t-test, and t-test for heterogeneous variances, at 5% significance level. Result A rate of 75% of patients preferred post-treatment silhouettes and changes were perceived regardless of the choice of either pre- or post-treatment profile. There was no significant difference between the cephalometric variables of the tracings that produced the silhouettes considered better or worse after the evaluation. Conclusion There was no association between the cephalometric results after treatment and the perception of esthetic improvement by patients treated for mandibular retrognathia.

Published: September 2019

Abstract Introduction: Treatments for rheumatoid arthritis (RA) and osteoarthritis (OA) can reduce, modulate inflammation, and reduce deformities. Low-Level Laser Therapy is a biomodulator and may aid in the clinical picture of these conditions. Objective: To analyze the parameters most frequently used to determine the responses of patients with RA and OA in controlled and uncontrolled clinical trials. Method: This is a systematic review with search of articles in English, Portuguese and Spanish in PUBMED, SCOPUS, LILACS and Web of SCIENCE, of articles published between 2006 and 2018. MeSH terms were used. Inclusion criteria: evaluation of LLLT in the evaluations, evaluation and evaluation of the period, controlled and uncontrolled clinical trials, full publications. The base date of the energy dosimetry and the analysis of mean, median and mode of energy per point and energy per treatment. Results: Three articles on RA and 16 on OA were included in this study. Regarding dosimetry, it was one of the most recent of the pain, being this one with a greater energy dose. In OA, most of the articles presented are of importance, with variability in the dosage applied. Conclusion: There are several reports for patient studies purposes, mainly with doses of 6 J per point and 48 J. In the joints affected with OA and AR, it would be important to publish more scientific articles with better methodological quality and description of dosimetry.
O governo Temer e a volta do neoliberalismo no Brasil: possíveis consequências na habitação popular
Authors: Souza Mariana Barbosa de , Hoff Tuize Silva Rovere
Published: September 2019

Resumo Este artigo objetiva descrever e exemplificar como o Brasil passa por uma transição do neodesenvolvimentismo para o neoliberalismo na segunda década do século XXI e apontar alguns possíveis desdobramentos desse processo nas políticas públicas de habitação. Considerando a afirmação de que, historicamente, o capitalismo no Brasil tem dependido de uma certa participação das classes populares para se desenvolver e analisando os Governos Lula e Dilma (2003-2016) em contraposição ao recente Governo Temer, pode-se chegar à hipótese de que o país passa por uma nova transição de regime econômico, de volta ao neoliberalismo adotado nos anos 1990 por Fernando Henrique Cardoso (FHC), e que essa transição pode ser um desafio ao desenvolvimento brasileiro, com consequências diretas na habitação popular. O artigo apoia-se em uma abordagem dialética e qualitativa, que é realizada mediante a análise e a interpretação dos referenciais teóricos e dos dados levantados com pesquisa documental.
Global stability of buildings’ structural systems considering beam-wall connections
Authors: DINIZ C. W. S. , LAGES E. N. , BARBOZA A. S. R.
Published: September 2019

Abstract Several factors influence the stability of concrete structures, such as building height, structural components’ rigidity, bracing system, beam-wall connection rigidity, among others. Global structural stability is evaluated according to NBR 6118/2014 by the α e γz parameters. This article aims to evaluate the global structural stability concrete structures considering the eccentricity of the beam-wall connections. With the aid of software Abaqus© and TQS©, reticulated models were analyzed to evaluate the contribution of the eccentricity of the beam-wall connections on the global stability and the rigidity of the connections. The geometric nonlinear effects were disregarded in these analyses. The stability parameters from NBR6118/2014 were evaluated in the frame models, as well as the flexibilization criteria from the TQS© software, LEPMOL e REDMOL. The results of the displacement analysis show an increase of 26.45%, comparing the centered connection to the more eccentric connection.

Published: September 2019

Abstract This paper aims to present the flexural behavior of hybrid GFRP (glass fiber reinforced polymer) concrete beams as sleepers to railway application. It was tried to obtain sleepers with adequate mechanical resistance, not susceptible to corrosion, durable and lighter than the sleepers in prestressed concrete. Pultruded fiberglass and polyester resin profiles were filled with high strength concrete and polyolefin fiber in the following proportions by volume: 1% and 2.5%. The beams were 1.06 meters long and had a 76 mm x 76 mm x 6 mm cross section, corresponding to a reduced model in a 1: 2.64 scale of a 2.80 meters long sleeper. In the bending tests, the load was applied at the center of the sleeper, as provided in the Brazilian standard NBR 11709 (2015) and American standard AREMA (2016). During the tests the applied load, the vertical deflection and the longitudinal tensile and compression deformations were measured in the center of the span. The influence of fiber addition on the strength, rupture mode and flexural modulus of elasticity of the hybrid beams was analyzed. Finally, the hybrid sleeper performance was compared to that of the prestressed concrete monoblock sleeper. The results obtained were satisfactory, indicating that the proposed hybrid sleeper is a constructively and technically feasible alternative.

Published: September 2019

Abstract This article aims to perform statistical analysis on the inclusion effects of waste tire rubber and fly ash from thermoelectric plants as mortar components for coating buildings. Reference mortars and mortars containing 5% and 10% rubber with a maximum grain size of 0.71 mm and mortars containing fly ash particles with a diameter of 45 μm were produced. Mortars containing rubber replaced 5% and 10% of the fine aggregate mass by this material and fly ash was added in 10% and 20% proportions compared to the cement volume. A 3² factorial experiment was performed on the mechanical properties of the compressive strength of mortars, applying analysis of variance (ANOVA) and surface response. The rubber waste material contributed to the decrease in compressive strength of the mortar and that factor displayed the highest significance in the response variable.
Reinforced concrete corbels strengthened with external prestressing
Authors: ROMANICHEN R. M. , SOUZA R. A.
Published: September 2019

Abstract Reinforced concrete structures may demand, throughout their lifetime, the increase of the capacity load due to eventual changes in the load configuration. In this context, corbels could be considered structural elements which present great challenges for installing strengthening solutions. The referred difficulty is due to the fact that the strength capacity of this kind of element is dependent on the strength of a diagonal concrete strut and a tensile steel tie, both located in a very short region also subjected to interferences. In the present paper, the behavior of reinforced concrete corbels strengthened with external prestressing is investigated. For that, nonlinear analysis of short corbels (a/d ratio between 0,5 and 1,0), strengthened or not, have been applied. Also, analytical models based on the Strut-and-Tie Model were developed and the obtained results were compared with experimental results. The obtained results have demonstrated that strengthening reinforced concrete corbels using external prestressing is a fast, efficient and safe solution.
Design of deep pile caps by strut-and-tie models
Authors: SANTOS D. M. , CARVALHO M. L. , STUCCHI F. R.
Published: September 2019

Abstract There are many methods for designing pile caps, but there is still no consensus on which one provides the best approach for the practical engineers. In Brazil, many structural designers use the classical Blévot method; however, the applicability of the method has been questioned after the revision of the NBR 6118 standard for design of concrete structures in 2014. To support structural designers, a strut-and-tie model has recently been developed that relates the classical method to the most current concepts of strut-and-tie models. The theoretical bearing capacity of four-pile cap obtained through several strut-and-tie models are compared with experimental tests. The results show that this recently developed model is suitable for the design of deep pile cap.
Interaction dam-reservoir: study of conservative and dissipative effects
Authors: SILVA S. F. da , PEDROSO L. J.
Published: September 2019

Abstract In this paper, the Laplace’s equation is solved analytically in the complex plane for the field of hydrodynamic pressures generated by the rigid body movement of a dam against a reservoir with infinite domain and incompressible fluid. The force the reservoir fluid exerts on the face of the dam is determined through the integration of the hydrodynamic pressure in the complex plane. The conservative effects (real part) and dissipative effects (imaginary part) of the force are analyzed as a function of the Froude number. The asymptotic solution of the aforementioned effects are also presented in this paper.

Authors: Valenzuela-Lara Marisol , Ponce-Ramos Marisol , Ruiz-Herrera Karen , López-González Agustín
Published: September 2019

Introduction. Despite evidence from harm reduction programs, there are limited data on their impact in Mexico. The Mexican National HIV Program has supported harm reduction programs implemented by community-based organizations both financially and technically. Objective. To obtain an estimate of HIV infections averted from 2015 to 2018. Method. A deterministic model was developed to estimate the number of infections, with harm reduction projects financed by CENSIDA and implemented by Community-Based Organizations, using data reported from the period 2015 to 2018. The benefit was obtained by estimating the costs of providing prevention programs and comparing the latter to the costs of providing care. Results. An analysis of 66,973 people included in harm reduction programs showed that an estimated 869 HIV infections were averted between 2015 and 2018. Potential savings obtained by providing these harm reduction services exceeded over $600,000 Mexican pesos for every infection averted. Discussion and conclusion. Harm reduction services play a key role in reducing the incidence of HIV in Mexico. Ensuring their financing is necessary since, combined with other services, they are a cost-effective tool for reducing the economic and public health burden of HIV/AIDS.

Authors: Diaz-Negrete David B. , Velázquez-Altamirano Marina , Benítez-Villa José L. , Fernández-Cáceres Carmen
Published: September 2019

Introduction. The evaluation of methadone maintenance programs reports generally positive outcomes. Objective. To explore the psychosocial factors that contribute to achieve treatment goals even when patients live in conditions of precariousness and exclusion. Method. Qualitative study of multiple cases, with a sample of 12 interviews with patients participating in a maintenance and detoxification program with methadone; a thematic and discursive-narrative analysis was undertaken. Results. We identified the predominance of a typical discursive scheme composed of clearly differentiated narrative segments: previous conditions, establishment of a relationship with the therapeutic system, process of adjustment as a part of treatment and social reintegration. Two main themes were also identified: addiction and dealing with substances, and the problem of normative integration; there was also an experience of acceptance and recognition that constitutes a central factor for treatment. Discussion and conclusion. These findings are discussed in light of the disaffiliated conditions of people using injected heroin and the need to consider psychosocial and normative adjustment as a relevant factor for treatment and social reintegration, which leads to the suggestion to include psychotherapeutic interventions to accompany and reinforce the process.
The Cyprus Question in the European Integration Processes (1960-2004)
Authors: Kovalskyi Stanislav
Published: September 2019

The article is devoted to the Cyprus issue in the context of the European integration processes from the Republic’s independence till the accession of Cyprus to the European Union in 2004. Forms and stages of Cyprus` integration policy were revealed in the article. The European integration was the main idea of the Cyprus history in the late 20th century and at the early 21th century. Therefore, the mentioned aspect became the subject of this research. Two lead strategies of the Cyprus policy towards European Communities were identified. The first one was the association within the framework of the customs union as a lead Cyprus policy in 1970-1980th. The second strategy was based on the principles of full membership in the European Union. The latter was occurring in the post Cold war era and had been succeeded in 2004. The home and foreign problems, formed so called Cyprus question, were characterized in the paper. Ethnic conflict’s consequences, artificial territorial division, unfinished peacekeeping operation were obstructing the European goal of the Cyprus Republic. European Commission considered Cyprus to be adjusted to the European high standards. Due to Greek Cypriot’s hard work for the juridical implementations and social and economic adaptations Cyprus was accepted to the EU. In the 1990s the European Union proposed its own way to maintain the Cyprus problem by proceeding intercommunion negotiations and UN Resolutions. This EU`s activity was failed in many points that was reflected in the paper. The British, Greek and Turkish opinion about the Cyprus integration was analyzed. The politic reaction of Greece and Turkey was also in the focus of view. An attention was paid to the Turkish community of Cyprus as a separated problem. The change of Turks Cypriots` status during integration policy of Cyprus was a prominent feature in attempting to solve Cyprus dispute. The Cyprus question is affecting the Turkish European policy badly. Therefore, this problem remains actual for the European history.
Effects of Nano-Lubricants on Power and CO Emission of a Diesel Engine: An Experimental Investigation
Authors: YILMAZ Ali Can
Published: September 2019

In this study, it was aimed to investigate the effects of copper (II)
oxide (CuO), copper zinc iron oxide (CuZnFe2O4) and
copper iron oxide (CuFe2O4) nanoparticle additives in
synthetic diesel engine oil (5W-40) at the fraction of 0.08 wt% on friction and
wear in piston ring-cylinder liner mechanism of the engine. In this regard,
Scanning Electron Microscope (SEM) analyses of the nanoparticles were first
carried out and via a linear reciprocating tribometer, friction coefficients
were determined on specimens comprised of the same material with real engine
piston ring. Subsequently, SEM analyses of the samples exposed to abrasion were
carried out to investigate the wear characteristics. In the second stage of the
experimental study, oil sump of the diesel test engine was filled with raw oil
(oil without nano additives) and prepared nano oils (oil+nano additives)
separately to unravel the effects of the lubricants on engine power and carbon
monoxide (CO) emissions. According to the results, it was determined that
CuZnFe2O4 nano lubricant was the most pronounced of all
in terms of tribological performance, engine power and CO emissions. The
results depicted that, in the best case, an average increment of 15% in engine
power and an average reduction of 18% in CO emissions with CuZnFe2O4 nano oil
were provided compared to that of the raw oil.

Background: At present, no documented anesthetic technique exists for use in liver transplant surgery. Presence of some controversies in anesthesia plan led us to compare effects of inhaled and intravenous anesthetics in liver transplant surgery.
Methods: All those brain dead patients who met the criteria of organ donation were included in the study. The donor's liver is matched with the recipient according to our liver transplant protocols and assigned consecutively to the recipients. In this study 78 patients who met the inclusion criteria, were divided into two groups.
All patients in group 1 were anesthetized with inhalation of sevoflurane and patients in group 2 were anesthetized with the IV injection of propofol. Percent of sevoflurane in inhaled gases and IV infusion dose of propofol was determined by a BIS guide to keep BIS between 40 and 45. Patients were monitored by NIBP, ECG, CO – Oximetry and BIS before and during induction of anesthesia. An arterial line from radial artery and Swan–Ganz–Catheter from right internal jugular vein were inserted for all patients.
Results: Mean of PCO2, PO2 and HCO3 were different between 2 groups (p=<0.05) and were higher in propofol group. Also, mean of Na and K were different in both groups and were higher in sevoflurane group, and no other significant differences found.
Conclusion: The results showed that the effect of propofol and sevoflurane on hemodynamics, coagulation status during liver transplant anesthesia, and hepatic and renal function of the patients after liver transplant is the same.

Published: September 2019

Anaesthesia management is always challenging in a patient who comes in emergency with multiple comorbidities. When we have to choose type of anaesthesia in such patients we have to keep in mind its adverse effects on various organs and cardiovascular system particularly in hemodynamically unstable patients. Epidural and spinal anaesthesia in these cases have their own complications on hemodynamics of the patient. Epidural Volume Expansion (EVE) technique is a known technique that allows to achieve surgical anaesthesia level with smaller dose than the conventional procedure. We report successful management of an emergency case with EVE technique.

A MATA COMO ESPAÇO DE ENCANTARIA: UMA RELAÇÃO COM A PENTECOSTALIDADE
Authors: Moura Rodolfo , Moraes Manoel Ribeiro de
Published: September 2019

Falar das presentes e diversificadas influências religiosas que o pentecostalismo herdou durante sua formação histórica requer uma análise abrangente. Contudo, o artigo tem a proposição de construir apenas uma breve análise que provoque o debate acerca da mata como espaço de encantaria  na cosmovisão pentecostal, sobretudo dos pentecostais que frequentam a vigília da mata, a qual comumente é denominada de “oração do monte” . Esse tipo de encontro ocorre, semanalmente, em uma zona de mata, no bairro de Val-de-Cães, em Belém. Dessa forma, a abordagem objetiva compreender possíveis elementos de ressignificação que o grupo frequentador faz de códigos da cultura religiosa dos povos tradicionais da Amazônia, onde ecoa, em sua forma de expressão religiosa, a importância da mata na qualidade de espaço mágico-religioso, logo, com traços de influência cultural xamânica. Desse modo, a abordagem atende o método qualitativo, produzido mediante observação participante e revisão bibliográfica, esta, especificamente, sobre a temática pentecostal das encantarias e do sincretismo, as quais ajudam na compreensão dessa relação da pentecostalidade com a mata, exteriorizada na vigília.

O quadro “A Conquista do Amazonas”, de Antônio Parreiras, é rico em detalhes e capaz de remeter o expectador ao período colonial, contudo, trata-se de uma produção do início do século XX e nele é possível ver a construção de uma identidade regional pela qual marca o nascimento do Estado do Pará para além das fronteiras com os outros estados da federação. A produção de um quadro com essa simbologia não poderia ser delegada a um pintor qualquer, nesse sentido, Antônio Parreiras foi responsável por pintar a sua obra-prima que ficaria no Pará como parte do projeto republicano de construção de símbolos nacionais. Com esta encomenda, Antônio Parreiras organizou a sua primeira tela histórica. Nesta perspectiva, o principal objetivo é identificar os diversos aspectos presentes na tela A Conquista do Amazonas de Antônio Parreiras. Ressaltando que a tela narra um dos grandes feitos do período colonial, mas a sua produção faz parte de um projeto de construção de uma identidade regional. Tanto que a tela está dividida em três momentos-chave. O primeiro relaciona-se ao ato de conquista, no qual a leitura do termo de posse é feita. No centro, os cinco membros da expedição chefiada por Pedro Teixeira ouvem de maneira solene, não havendo manifestação de desrespeito; O segundo momento relaciona-se com a ideia de civilização em que o europeu conduz o elemento indígena em direção à vivência em sociedade e ao progresso. E, por último, o predomínio quase absoluto das tecnologias europeias, uma vez que as velas das embarcações portuguesas ocupam lugar de destaque se comparadas àquelas produzidas pelos indígenas amazônicos.

Published: September 2019

Este artigo, é parte de uma produção acadêmica científica de Conclusão de Curso, versa sobre a diversidade cultural na Escola do Campo Ribeirinha, traz como questão central o trabalho educativo do professor e sua prática pedagógica que possibilite o reconhecimento da diversidade cultural do espaço da sala de aula e potencializa a inter-relação entre os sujeitos do processo educativo. Fazemos um recorte dos resultados que objetivou analisar a metodologia do (a) professor(a) para trabalhar com a diversidade cultural na escola do campo ribeirinha. A pesquisa foi realizada no município de Benjamin Constant, Estado do Amazonas, com base na abordagem qualitativa utilizando-se de observações participantes em sala de aula e na escola, entrevistas semiestruturadas e análises de documentos, que permitiram discutir e refletir sobre o contexto educacional, as singulares e especificidades dos sujeitos no contexto escolar. A investigação apontou que apesar da existência de uma grande diversidade cultural no cotidiano da sala de aula e os parâmetros legais e didáticos que orientam o trabalho pedagógico, esta diversidade não é contemplada nas práticas docentes de sala de aula e tampouco no ambiente educacional. Diante do exposto, se impõem um grande desafio para modificar a forma como a prática efetiva, proporcionando vivências interculturais, sobretudo, nas metodologias que possam considerar os aspectos socioculturais oriundos dos educados, seus familiares e comunidade do entorno da escola. Por fim, é necessário uma maior aproximação dos conhecimentos teóricos com os conhecimentos e vivências culturais dos educandos, com vista a uma interação dialógica entre os sujeitos.
Genealogía del pensamiento creativo y su necesidad en la realidad universitaria
Authors: Ramírez Tarazona Josué Vladimir , Rincón Sánchez Astrith Eugenia
Published: September 2019

En el presente artículo se revisa la literatura fundante del desarrollo del pensamiento en interacción con la creatividad como una actividad esencialmente humana, analizada en un contexto universitario. La investigación aborda un entorno global universitario en el cual la creatividad, de una parte, se potencia por el arte y el juego, y de otra se somete, debido a fenómenos mundializados, la innovación, la productividad económica y el mercadeo, entre otros, que modifican la realidad educativa. La relevancia del estudio se encuentra en una situación de impacto generacional, ante la dificultad cada vez mayor de los profesores universitarios en atraer a los estudiantes hacia el conocimiento, toda vez que ellos en la actualidad se encuentran seducidos por el hedonismo contemporáneo y su vida social. La investigación tuvo un método mixto, con componente cualitativo y otro cualitativo, el cual se desarrolló en tres etapas; i. Una actividad hermenéutica, ii. Entrevistas estructuradas aplicadas a profesores especializados que desarrollan didácticas creativas, y iii. Dos cursos con profesores para poner en práctica la propuesta docente creativa. Como conclusión principal se argumentó que el pensamiento se desarrolla en relación con el tipo de sociedad de la cual emerge, y en el aula universitaria emana de la creatividad. Es una actividad dual, lógico-emocional, y fruto de esta interacción fluye el conocimiento como una construcción social.
Temperature State of the Anisotropic Spherical Layer During Convective Heat Exchange with the Environment

Published: September 2019

The paper focuses on the process of steady heat conduction in a spherical layer of a heat-shielding coating made of anisotropic material. The inner surface of the layer is ideally heat-insulated but its outer surface is exposed to heating by convective heat exchange with the environment, the temperature of which varies along this surface. Based on the obtained solution of the linear heat conduction problem, we quantitatively assessed the influence of the degree of anisotropy of the coating material, its relative thickness, intensity of convective heat transfer, and uneven distribution of ambient temperature on the equalization of temperature distribution in the spherical layer. The results obtained can be used to select the characteristics of an anisotropic coating material in order to reduce the temperature of the outer surface of the spherical layer in the zone of the most intense heating.

Published: September 2019

The long-term deep-sea experiment on study of macroscopic quantum nonlocal correlations of natural large-scale random dissipative processes has been conducted in Lake Baikal since 2012. Correlations of the probe processes in detectors insulated from classical local impacts, between each other and with the large-scale source-processes are studied. These correlations are observed at extremely low frequencies and characterized by the large time shifts. The most important feature of random process nonlocal correlations is presence of a considerable advanced component in them. The dominant source is solar activity. At the same time, the correlations with macroturbulence in the Baikal active layer are revealed. The advanced nonlocal correlations can be applied to forecast the processes with big random component. A forecast series of macroturbulence sea current velocity variations in the active layer, which demonstrated forecast accuracy of the order of tenths of cm/s at an advance of the order of month, has been obtained by the latest experimental data. The possibility of using nonlocal correlations to forecast solar activity in advance of the order of the year has also been demonstrated.
Zagadki Spitamegeranomachii, czyli o komentarzu edytorskim do poematu Jana Achacego Kmity
Authors: Goszczyńska Aleksandra
Published: September 2019

Artykuł Zagadki edytorskie „Spitamegeranomachii” Jana Achacego Kmity jest wyrywkowym opisem prac nad dwuczęściową publikacją „Spitamegeranomachia” Jana Achacego Kmity – edycja…, która ukazała się w czasopiśmie „Meluzyna. Dawna literatura i kultura” (2017 r.). Nowa edycja poematu opierała się na pierwodruku (1595 r.) i jego XIX-wiecznej reedycji (1897 r.), spożytkowano też przyczynki edytorskie Aleksandra Brücknera i Jacka Sokolskiego. Artykuł obrazuje trudności pokonane w trakcie komentowania tekstu. Wskazuje się jednocześnie na brak obszerniejszego opracowania struktury gatunkowej poematu: kwalifikowany jest on jako heroikomikum, ale też jako poemat aluzyjny lub satyryczno-polityczny.

Wstęp

Aby obniżyć częstość występowania próchnicy zębów w Żywcu, władze samorządowe wdrożyły program dedykowany dzieciom w wieku 4–15 lat. Program obejmował działania edukacyjne i profilaktyczne (badanie jamy ustnej oraz lakowanie I i II stałych zębów trzonowych). Celem pracy było zmierzenie skuteczności programu zdrowotnego.

Materiał i metody

W badaniu wzięli udział 12-letni uczniowie: z miasta Żywiec objęci programem profilaktycznym (grupa P; n = 441); z miasta Żywiec nieobjęci takim programem (grupa CT; n = 131) oraz ze wsi w powiecie żywieckim, również nieuczestniczący w programie (grupa CR; n = 135). Skuteczność programu była oceniana na podstawie wiedzy dzieci na temat zdrowia jamy ustnej oraz oceny stanu uzębienia, w szczególności pierwszych i drugich zębów trzonowych stałych.

Wyniki

Dzieci z grupy P miały większą wiedzę (p < 0,001), obserwowano u nich niższą częstotliwość próchnicy zębów stałych (p < 0,001), niższe średnie wartości DMFT (1,3; p < 0,001) i DMFS (1,4; p < 0,001), niższe wartości SiC (3,2; p < 0,001) oraz wyższe wskaźniki lakowania I (p < 0,001) i II (p < 0,001) zębów trzonowych niż w obu grupach kontrolnych. Dla porównania w grupie CT: DMFT = 4,5; DMFS = 5,2; SiC = 7,2, w grupie CR: DMFT = 3,5;
DMFS = 4,3; SiC = 7,0. Wskaźnik leczenia zębów w grupie CR (0,44) był znacznie niższy niż w grupach P (0,80) i CT (0,76).

Wnioski

Realizacja programu profilaktycznego o takim charakterze mogłaby przynieść korzyści nie tylko w Polsce, lecz także w krajach, w których stan zdrowia jamy ustnej jest bardzo niekorzystny.

Core-Shell Nanofiber Containing Large Amount of Flame Retardants via Coaxial Dual-Nozzle Electrospinning as Battery Separators

Published: September 2019

Lithium-ion batteries have attracted enormous interests recently as promising power sources. However, the safety issue associated with the employment of highly flammable liquid electrolyte impedes the further development of next-generation lithium-ion batteries. Recently, researchers reported the use of electrospun core-shell fiber as the battery separator consisting of polymer layer as protective shell and flame retardants loaded inside as core. In case of a typical battery shorting, the protective polymer shell melts during thermal-runaway and the flame retardants inside would be released to suppress the combustion of the electrolyte. Due to the use of a single precursor solution for electrospinning containing both polymer and flame retardants, the weight ratio of flame retardants is limited and dependent. Herein, we developed a dual-nozzle, coaxial electrospinning approach to fabricate the core-shell nanofiber with a greatly enhanced flame retardants weight percentage in the final fibers. The weight ratio of flame retardants of triphenyl phosphate in the final composite reaches over 60 wt.%. The LiFePO4-based cell using this composite nanofiber as battery separator exhibits excellent flame-retardant property without compromising the cycling stability or rate performances. In addition, this functional nanofiber can also be coated onto commercial separators instead of being used directly as separators.
