Orthodontic movement of a contralateral maxillary central incisor across the midpalatal suture
Authors: Kato Chiho , Kokai Satoshi , Ono Takashi
Published: March 2020

There are several options for replacing a missing maxillary central incisor in orthodontic treatment. Substituting a missing central incisor with the contralateral one can be a useful approach to reduce the number of teeth that require extraction during the treatment. Normal tooth movement across an ossified midpalatal suture (MPS) has only been observed in an animal experiment. Herein, we describe the treatment of a 26-year-old woman who had lost multiple teeth on one side, including the maxillary right central incisor, which required extraction due to endodontic failure. The maxillary left central incisor was moved into the position of the maxillary right central incisor. All other left maxillary teeth were moved mesially to close the space. After completion of orthodontic treatment, acrylic build-up was performed on the maxillary left lateral incisor, which underwent morphological modification to replicate the morphology of a maxillary right incisor. The patient was pleased with the treatment outcome. Cone-beam computed tomography provided evidence of tooth movement across the MPS. Although the movement of the tooth across the MPS is feasible, the treatment plan should also take other treatment options into consideration.
Lingual bonded retainers: A case series of complications and resolutions
Authors: Kim Tae-Kyung , Baek Seung-Hak
Published: March 2020

Objective:

The objective of the study was to describe the types, causes, and recommendations for the prevention/ management of complications related with lingual bonded retainers (LBRs) during the retention period.

Materials and Methods:

The retention protocol was a combined use of the LBRs made from 0.0175 multistrand wire and bonded on the maxillary and mandibular anterior teeth by DuraLay resin transfer method and a removable retainer at both arches for nighttime wear. Nine cases, which did not show bonding failure or fracture of LBR, were described to explain the complications including unexpected tooth movements and gingival problems.

Results:

The types of complications were spacing, loss of alignment, change in transverse position, angulation or torque of the crown, gingival recession, and black triangle. There are three possible causes for these complications: (1) Active force generated by LBR, which was not passively fabricated or bonded, (2) deformation of LBR induced by heavy biting force or traumatic occlusion, and (3) untwisting force of strand in round flexible multistrand wire. These complications can be prevented or managed by (1) fabrication of LBR on a working model to make it passive, (2) use of a jig to position LBR during bonding to avoid deformation by finger pressure, (3) supplemental use of a removable retainer for nighttime wear, (4) early detection of bonding failure, deformation, or fracture of LBR, and (5) immediate removal of LBR and use of a new removable retainer for resolution of complications.

Conclusion:

Clinicians should check the existence of these complications from the start of retention and inform the patient of the possibility of retreatment.

Authors: Kapoor Harit , Nisiewicz Michael J. , Jayavarapu Ravi , Gedaly Roberto , Raissi Driss
Published: March 2020

Objective:

Microwave ablation (MWA) of liver malignancies has gained much traction over the past 5 years. However, MWA carries relatively higher rates of residual disease compared to resection. Likelihood of MWA success is multifactorial and newer devices with more reliable ablation zones are being developed to overcome these drawbacks. This manuscript is a review of our first 100 liver ablations with the newer single antenna high powered MWA system.

Materials and Methods:

Retrospective chart review of patients that underwent MWA for either primary or secondary hepatic malignancies between March 2015 and July 2016 was conducted. The complete ablation rates, rate of new lesions, complications, and short-term survival were analyzed. Multiple statistical tests, including multivariate regression, were used to assess risk factors for local residual and recurrent disease.

Results:

Fifty-three patients (median age 61 ± 9 years, 39 males) underwent 100 MWAs. Of the 100 lesions ablated, 76 were hepatocellular cancers (HCCs) and 24 were metastases. Median lesion size was 16 ± 9 mm. Seventy- five of these patients had multifocal disease targeted in the same session. Seventy patients had cirrhosis (median model for end-stage liver disease score 9 ± 3; Child-Pugh B and C in 42%). An 83% complete lesion ablation rate was seen on follow-up imaging with liver protocol magnetic resonance imaging/computed tomography (median follow-up of 1 year). The minor complication rate was 9.4% with no major complications or 30-day mortality. Despite this, evidence of new foci of hepatic disease was found in 47% of patients, the majority (80%) of which were in HCC patients (P < 0.01) and most of these new lesions were in a different hepatic segment (64%). Degree of cirrhosis (P < 0.01), presence of non-alcoholic steatohepatitis (NASH) (P = 0.01) and lesion’s subcapsular location (P = 0.03) was significant predictors of residual disease. With the subset analysis of only HCC lesions larger than 1 cm, only the presence of NASH remained significant.

Conclusion:

The single probe high power MWA of malignant hepatic lesions is safe and effective with minimal morbidity. Degree of cirrhosis, NASH, and subcapsular location was associated with an increased rate of residual disease on short-term follow-up.

This study aims to find out how students' speaking skills are developed through the Communicative Language Teaching approach. The significance of this research is to provide information for readers, especially for Pamona people as native speakers of the language, about the tenses in the Pamona language. Researchers used the Communicative Language Teaching (CLT) theory by Richard and Rodgers to develop students' speaking skills. The results of this study indicate that the objectives of this study have been achieved. The ability to speak English students successfully developed through the application of communicative language teaching approaches, through learning that triggers students to speak actively in the classroom through conversations as an exercise. In the first cycle all students attend the test. The results of the test in the first cycle were 12 students failed (33.3%) and 24 students (66.7%) passed. Achievement of the average grade of the class is also still low with a score of 65.8 grades C. Researchers then reflect on the learning process in this first cycle to be applied in the second cycle. In the second cycle, all students attend the test. The results of this test were 33 students (91.6%) successfully passed the test and 3 students (8.4%) failed. From the explanation of the results of the second cycle above, it appears that in this cycle the completeness criteria for class has been reached, in which 80% of the total number of students must achieve grades A, B or C or a value of more than 65. Students succeed in developing their English speaking skills because supported by teaching approaches that trigger students to speak and practice the functions of the language being learned.

Studies on Computational Molecular Interaction Between SARS-CoV-2 Main Protease and Natural Products
Authors: Manish Manish
Published: March 2020

A combination of docking approaches, scoring functions, molecular dynamic simulation, and literature mining have been employed to screen readily available natural products (unique 27256 chemical entities, 598435 unique compounds), which can inhibit the SARS-CoV-2 main protease. Theaflavin digallate, a major constituent of black tea, has been observed to be as three top hits after the virtual screening of 598435 unique compounds. The main protease-theaflavin digallate complex appeared to be in the metastable stage and interact with critical active site residues of the main protease during molecular dynamics simulation for 200 ns. Invitro evidence on main protease inhibition of 2003 SARS-CoV by theaflavin digallate is available in the scientific literature. As evident by the dynamics of intermolecular interactions, theaflavin digallate, forms approximately three hydrogen bonds with Glu166 of main protease, mostly through hydroxyl groups in the benzene ring of benzo(7) annulen-6-one. Glu166 is the most critical amino acid for main protease dimerization, which in turn, is necessary for catalytic activity. We have employed chloroquine and epigallocatechin gallate (green tea component) as a control set. Based on computational molecular interaction and data available in scientific literature, theaflavin digallate can inhibit the main protease of SARS-CoV-2.
First-principles insight into CO hindered agglomeration of Rh and Pt single atoms on ZrO2
Authors: Kauppinen Minttu M. , Melander Marko , Honkala Karoliina
Published: March 2020

In this first-principles study we evaluate the thermodynamic and kinetic stability of Rh and Pt single-atoms (SAs) and subnano clusters on the monoclinic zirconia surface with and without a CO atmosphere. To address the kinetic stability and agglomeration of SAs to clusters and nanoparticles, a non-equilibrium nanothermodynamic approach is developed and parametrised using data computed with density functional theory. The bare subnano clusters are more stable than SA and become more so with increasing size, which means the agglomeration is always favoured. CO binds strongly to the single atoms and clusters, and our atomistic thermodynamics treatment indicates that some CO will be present even at ultra-high vacuum conditions. A CO atmosphere is shown to hinder cluster growth from SA, and is even capable of spontaneous cluster disintegration in the case of Pt clusters. Analysis of the CO stretching frequencies reveals that subnano clusters and single atoms should give peaks in the same region, and that using them to distinguish between surface species requires caution.
Exact Generalized Kohn-Sham Theory for Hybrid Functionals
Authors: Garrick Rachel , Natan Amir , Gould Tim , Kronik Leeor
Published: March 2020

Hybrid functionals have proven to be of immense practical value in density functional theory calculations. While they are often thought to be a heuristic construct, it has been established that this is in fact not the case. Here, we present a rigorous and formally exact analysis of generalized Kohn-Sham (GKS) density functional theory of hybrid functionals, in which exact remainder exchange-correlation potentials combine with a fraction of Fock exchange to produce the correct ground state density. First, we extend formal GKS theory by proving a generalized adiabatic connection theorem. We then use this extension to derive two different definitions for a rigorous distinction between multiplicative exchange and correlation components - one new and one previously postulated. We examine their density-scaling behavior and discuss their similarities and differences. We then present a new algorithm for obtaining exact GKS potentials by inversion of accurate reference electron densities and employ this algorithm to obtain exact potentials for simple atoms and ions. We establish that an equivalent description of the many-electron problem is indeed obtained with any arbitrary global fraction of Fock exchange and we rationalize the Fock-fraction dependence of the computed remainder exchange-correlation potentials in terms of the new formal theory. Finally, we use the exact theoretical framework and numerical results to shed light on the exchange-correlation potential used in approximate hybrid functional calculations and to assess the consequences of different choices of fractional exchange.

Authors: Ambroziak Andrzej , Lange Artur , Białucki Piotr , Derlukiewicz Wiesław , Szymczak Eryk
Published: March 2020

The paper presents the results of qualitative tests of Cu-Al joints made by soldering, brazing and resistance welding. Aluminum and copper tubes with a diameter of 6.9 mm, used, among others in refrigeration systems, were soldered with ZnAl2 and AlSi12 filler metal. In addition, similar connections were made by resistance welding. Macroscopic tests of soldered and welded joints were carried out and the hardness distribution on the cross-section of joints was determined. The analysis of research results allowed to state that resistance welding of Cu-Al joints can be a good alternative to the soldering process, especially in series production, due to the possibility of easy application of process mechanization.

Performance Enhancement of Coherent Optical OFDM System Using LMS Algorithm
Authors: Bharti Manisha
Published: March 2020

Instability of the local oscillator causes phase noise – a phenomenon that is a disadvantage and is considered to be a major obstacle in the functioning of coherent optical orthogonal frequency division multiplexing (CO-OFDM) systems. An attempt has been made in this paper to reduce the eﬀects of common phase errors generated by phase noise. In this paper, a least mean square (LMS) based algorithm is proposed for estimation of phase noise. Using this proposed algorithm, the major problem of phase ambiguity caused by cycle slip is avoided and the bit error rate is greatly improved. Further, there is no requirement for modifying the frame structure of OFDM using this algorithm. A CO-OFDM system with the 8-PSK technique is used to implement the algorithm concerned. Furthermore, the algorithm, using the 8-PSK modulation technique, is analyzed and compared with the existing QPSK technique and with other algorithms. The investigations reveal that 8-PSK outperforms existing LMS algorithms using other techniques and signiﬁcantly reduces the bit error rate.

Published: March 2020

O presente trabalho tem por objetivo apresentar as contribuições de uma oficina pedagógica com reportagens de jornais sobre o desastre da Samarco em 2015 no processo de ensino e aprendizagem de alunos do 3° ano do ensino médio. O referencial teórico-analítico adotado nesta pesquisa se pautou na Teoria Ator-Rede (TAR). Segundo a TAR humanos e não-humanos possuem a mesma importância ontológica e que quando se analisa uma prática sociomaterial como um processo de ensino deve-se investigar a aprendizagem como um “efeito” das associações e fluxos das redes performadas. Nossos resultados indicam que a oficina contribuiu para a aprendizagem dos alunos, uma vez que esses sujeitos se envolveram em novas alianças formadas durante o desenvolvimento da oficina. Entendemos que a oficina com jornais deve ser difundida e desenvolvida nas escolas, bem como os objetos, como os jornais, ser tomados para análise com a mesma relevância que as entidades humanas.
A Educação Ambiental para o desenvolvimento sustentável no novo currículo da Cidade de São Paulo
Authors: Yoshioka Caio César de Sousa , Frenedozo Rita de Cássia
Published: March 2020

A Educação Ambiental surgiu do movimento ambientalista preocupado com os impactos ambientais provocados pelas ações antrópicas no planeta e foi adotada por organismos internacionais, em especial a ONU. A Educação Ambiental (EA) para o desenvolvimento sustentável ganhou relevância internacional a partir da Eco-92 e o advento da Agenda 21 e posteriormente da Agenda 2030, na qual os países signatários do acordo se comprometeram a adotar os 17 Objetivos de Desenvolvimento Sustentável (ODS). Para conceber a EA para o desenvolvimento sustentável é imprescindível a elaboração de currículos escolares que estabeleçam aprendizagens que permitam aos estudantes entenderem o seu papel e o dos governos para com o desenvolvimento sustentável. Neste sentido, o presente trabalho tem por objetivo realizar uma análise crítica do Currículo da Cidade para a área de Ciências Naturais quanto a EA para o desenvolvimento sustentável. Foram analisados criticamente os documentos oficiais nacionais e internacionais que serviram de base para a elaboração do Currículo da Cidade quanto as concepções de EA e desenvolvimento Sustentável. Os conteúdos de aprendizagem disponíveis nesse currículo mostraram forte intenção da prefeitura de São Paulo para com o desenvolvimento crítico e cidadão dos estudantes ao adotar como norte a Educação para o desenvolvimento sustentável.
Educação Ambiental pelo viés da argumentação: o panorama e as possibilidades desta relação
Authors: Pezarini Agnaldo Ronie , Maciel Maria Delourdes
Published: March 2020

Em pleno século XXI a educação precisa voltar o seu olhar para a urgente necessidade de se realizar a inserção da educação ambiental no contexto escolar, de modo a promover a construção da habilidade de se posicionar criticamente frente à já instalada crise socioambiental. Neste caso, fica a indagação: de que maneira o ambiente escolar e os protagonistas do processo educativo podem construir tal habilidade? Acreditamos que isso é possível desde que no ambiente escolar as práticas pedagógicas se pautem no desenvolvimento da habilidade de argumentar, fato este que por sua vez é condição para o desenvolvimento da reflexão crítica dentro do contexto socioambiental. É dentro deste contexto que este artigo tem como objetivo dialogar sobre o seguinte problema: Como a argumentação científica possibilita e favorece a educação ambiental? E, com isso, identificar as possibilidades frutíferas da educação ambiental conduzida pelo viés da argumentação. Os resultados revelaram que, a educação ambiental pelo viés da argumentação facilitaria a compreensão por parte dos educandos e educandas da necessidade de pensar e repensar suas ações para planejar atitudes sustentáveis ao meio ambiente.

Contribution: The study contributes to understanding specifics and differences in representing extraordinary socio-economic events by different types of media.

Findings: Key findings are that these media have constructed different realities surrounding the tragic events and exhibited informing distortions to different degrees.

Recommendations for Practitioners: Practical implications of this study are relevant for the institutional and individual clients of informing with regard to selecting appropriate media for use. There are also implications for informers with regard to reducing distortions in informing.

Recommendation for Researchers: Social media could be a channel for alternative learning rather than manipulation. Mainstream media were confirmed to be a loudspeaker for authorities as postulated in critical media research, and analytical media provided influential, deeper technical analysis.

Future Research: As the Boeing case unfolds, it would be interesting to investigate any evolution in mediated realities.
A Low-Cost Microcontroller Based Air Temperature, Humidity and Pressure Datalogger System Design for Agriculture
Authors: POLAT M. Yağmur
Published: March 2020

Nowadays, it is accepted that climate change can threaten food safety. Losses in production areas due to climate change have the potential to create major devastating effects. In agricultural areas, rapid and effective measures should be taken against climate parameters that are not under human control. For this purpose, approaches such as precision or smart agriculture are becoming widespread. Low cost microcontroller-based devices that can help to take the necessary measures by rapidly measuring the basic climate parameters are gaining importance especially in the lands of small scale agricultural enterprises. For this purpose, developed a customizable and re-programmable datalogger system which can measure the basic meteorological values for agricultural purposes under field conditions with low-cost parts. The system consist of an Ardunio UNO R3 microcontroller card, a Bosch Sensortech BME280 integrated environmental sensor, a data storage unit, a LCD and an USB supported battery unit which allows the system to be used as a portable. The BME280 sensor is widely used in scientific studies, can measure air pressure, relative humidity and temperature, and communicate with microcontrollers. For the operation of the system, a software was developed in Arduino IDE (Internal Development Environment) and installed on microcontroller of Arduino UNO R3. The system was left on outdoor conditions with a top cover for one week in spring and one week in summer and it was found that it could record data continuously for one hour intervals.

Este artigo tem como premissa principal investigar como designers podem aplicar as abordagens críticas do pensamento de sistemas (systems thinking) para o diagnóstico de grupos sociais. Para isso, faz-se primeiramente uma abordagem teórica sobre assuntos pertinentes como Design, Artesanato e teorias de sistemas interpretativistas e críticos como Total Systems Intervention (TSI) e a Critical Systems Heuristics (CSH). Depois, apresenta-se uma descrição do caso de projeto social investigado neste trabalho, o Rede de Mulheres, oferecido pela secretaria da Mulher e Assuntos da Família de Apucarana, no estado do Paraná. Então, caracteriza-se a coleta de dados no projeto e a relação das informações com as teorias de sistemas críticos. Ao final da aplicação da CSH, foram identificados três pontos para intervenção de design: (I) capacitação das artesãs para repassarem os conhecimentos a fim expandir e perpetuar o grupo; (II) rever os preços dos produtos e a estratégia de divulgação de procedência deles; e (III) intervenção do Design de Serviço no sistema a fim de mitigar desigualdades de poder.

Authors: Santos Daniel Pinheiro , Lima Bessa Sofia Araújo
Published: March 2020

A utilização do adobe pelo homem é datada desde os primeiros modelos habitacionais que se tem registro. No Brasil, a técnica foi amplamente utilizada no período colonial, passando por diversos cenários, tendo seu uso declinado a partir da Revolução Industrial. Com os crescentes problemas ambientais causados pelo uso desenfreado de novos materiais, o adobe, dentre outras técnicas de construção com terra, ressurge com potencial de aplicação, principalmente pelo baixo impacto ambiental associado. Este trabalho teve como objetivo analisar historicamente a produção do conhecimento sobre o adobe no panorama nacional, desde o período colonial até os dias atuais com enfoque nos últimos 10 anos, buscando entender seu processo dinâmico de atuação tanto na paisagem arquitetônica brasileira, como no aspecto sociocultural associado, identificando as causas da retomada no seu uso por meio da questão da sustentabilidade. Os resultados evidenciaram um aumento substancial no número de publicações nesse período, por outro lado, Por outro lado, identificou-se uma demanda considerável por novas pesquisas na área, além da atuação política e social para a normatização, na disseminação da técnica tanto em âmbito acadêmico como na cadeia da construção civil nacional por sua ligação com as questões relativas às construções mais sustentáveis.

O envelhecimento populacional é uma realidade, sendo que o aumento da esperança média de vida acarreta maior morbilidade nos indivíduos idosos e, consequentemente, um maior grau de dependência por parte destes. Na sequência destas alterações demográficas surgem alterações estruturais em termos familiares, com necessidade de estabelecer um prestador de cuidados para determinado indivíduo dependente.As repercussões associadas ao processo de cuidar são várias, atingindo diversas áreas da vida do cuidador. Existem disponíveis vários instrumentos para avaliação da sobrecarga do cuidador: Carer Assessment of Difficulties Index, Carer Assessment of Satisfactions Index, Carer Assessment of Managing Index, Carers’ Assessment of Managing Index, Escala de avaliação da Satisfação com o Suporte Social e a Burden Interview Scale de Zarit. Estas avaliam diferentes áreas da vida do cuidador, desde a saúde física, mental, área social e mesmo financeira. Estes instrumentos devem ser utilizados de forma sistemática para identificar situações de sobrecarga precocemente.
Infant and Under Five Mortality Rates in Nigeria: An Impact Analysis of Macroeconomic Conditions
Authors: Raji Rahman Olanrewaju
Published: March 2020

Over the years, the rising unfriendly macroeconomic environment is a contributing factor to the infant and under-five mortality rate in Nigeria. The study investigated the role of macroeconomic conditions on infant and under-five mortality rates in Nigeria for the period 1986–2017 using the fully modified OLS technique. The results show that the unfriendly macroeconomic policy environment such as the instability of inflation rate, unemployment and exchange rate enhanced the increased level of infant and under-five mortality rate in Nigeria.  The study recommends that the authority should adopt more pro-growth policies that can ensure and maintain sound domestic macroeconomic policies to stem child mortality rate and promote economic growth through investment in food production and related investment in health. Most importantly, macroeconomic policies and institutions are highly needed to be strengthened in order to have a friendly macroeconomic environment which will in turn improve the population health of the country which can enhance sustainable and long term dietary as well as nutritional pattern of young age children and adult.
Assessment of Energy Intensity Indicators in Libya: Case Study

Published: March 2020

Energy-efficient technologies provide chances for money savings and reducing environmental damages related to energy use. This paper aims to assess the energy efficiency in Libya and tools to promote its implementation. In addition, it seeks to present measures and programs that could be foreseen in the transformation sector and some end users.

Data of energy intensity in Libya was taken from different recognized sources such as World Development Indicators (WDI) - World Bank, and Enerdata web site. The data was collected, assembled, and analyzed using Ms Excel sheets. Results were plotted and compared to World average and Africa or with (Middle East and North African) MENA countries where ever data is available. The main indicators over almost quarter of a century (1990-2014) were presented and changes over this period were indicated.

It could be concluded that primary energy intensity for Libya during (2000- 2014) is comparable to world average values and for Africa and the final energy intensity has increased at only 0.7% per year during the same period. As an oil producer and exporter country, the ratio of final enrgy intensity to primary energy intensity in Libya has increased at a rate of 1.1% during (2000-2014), which is greater than the World average and African countries.  The rate of energy intensity of transport has increased by 6.9 % per year for the period (1990-2014) and 7.8% per year for the period (2000-2014) compared to the world improvement (-1.8%) per year and for Africa (-0.3) % per year for the period (2000-2014)). This is due to lack of regulations and measures concerning this sector and increased number of private cars. Suitable measures and policies should be taken towards this sector to improve its performance since it contributes to the highest share of energy consumption. The highest share of electric energy consumption is at residential, then commercial and service end use, followed by street lighting. There is a good potential for energy saving at these sectors.
Nonlinear Analysis of Progressive Collapse of Reinforced Concrete (RC) Building by Different Kinds of Column Removal
Authors: Ma Wenchen
Published: March 2020

Building collapse mostly can be caused by the loss of loading capacity in a primary structural component, resulting in the failure of surrounding elements, which in turn cause a failure propagation. Progressive collapses may be accidental, due to design deficiencies or errors, material failure or natural phenomenon (e.g. earthquakes) but it can be prevented by upgrade the concrete components’ material [1][2]. Well-engineered RC buildings generally have a good performance under normal loading conditions. However, faulty design, construction errors, material deterioration, and overloading are always occurred. When part of structure fails, the total load in the whole system will not disappear, which means the load will be redistributed unevenly to the adjacent part of structure. This phenomenon revealed that sustained high stresses in RC elements can lead to catastrophic collapse. Due to very few of papers did the research on the RC elements under high stress level sustained load, relevant experiments should be performed in this area. This paper gives the suggestions about how to apply the load in an experiment if researchers want to know the behavior of elements near to collapse especially focus on RC columns.

The decision of traffic congestion degree is an important research topic today. In severe traffic jams, the speed of the car is slow, and the speed estimate is very inaccurate.This paper first uses the data collected by Google Maps to reclassify road levels by using analytic hierarchy process. The vehicle speed, road length, normal travel time, traffic volume, and road level are selected as the input features of the limit learning machine, and the delay coefficient is selected. As the limit learning machine as the output value, 10-fold cross-validation is used. Compared with the traditional neural network, it is found that the training speed of the limit learning machine is 10 times that of the traditional neural network, and the mean square error is 0.8 times that of the traditional neural network. The stability of the model Significantly higher than traditional neural networks.Finally, the delay coefficient predicted by the extreme learning machine and the normal travel time are combined with the knowledge of queuing theory to finally predict the delay time.
