Authors: Silva George B. , Santos Lucas F. , Faria Roberto M. , Graeff Carlos F. O.
Published: December 2018

In this work electrically detected magnetic resonance (EDMR) is used to study the electronic properties of poly(2-methoxy-5-(2'-ethyl-hexoxy)-1,4-phenylene vinylene) (MEHPPV) diodes. Two kinds of MEH-PPV diodes were characterized. The first one was a bipolar light emitting diode whose structure was ITO/MEH-PPV/Al. In this diode the EDMR signal is composed of two lines, a line that can be fitted by a lorentzian with peak-to-peak linewidth of 5.0 ± 0.5 G and the other best fitted with gaussian line with a linewidth of 24 ± 1 G. The g factor of both components is 2.002 ± 0.001 and signals were only observed at forward bias. The second diode is a hole only device, with a structure ITO/MEH-PPV/Au, the EDMR signal in this case is dominated by a gaussian line with peak-to-peak linewidth of 5 ± 1 G and average g factor of 2.0014 ± 0.0002. In high forward bias (V > 30 volts at T = 130K) a second line could be observed with a linewidth of 10 ± 2 G and a g factor of 2.0012 ± 0.0004. The signal from both types of diodes is quenching, and tipically10-5 in amplitude. The EDMR signal is assigned to the spin-dependent fusion of two like-charged polarons. Our results indicate that the narrower component is coming from positive polarons while the broader to negative polarons.

Published: December 2018

The organic/cathode interface plays an important role in device degradation of organic light-emitting diodes (OLEDs). The interface between 8-hydroxyquinolino aluminium (Alq) and Mg:Ag cathode in OLEDs, operated for some time, was characterized using Xray photoemission spectroscopy (XPS). An in-vacuum peel-off method was used to separate the buried interfaces. XPS results indicate that Alq molecules break down, resulting in formation of fragmented hydroxyquinolino, Mg oxides, and metallic Al at the interface. It is also found by XPS depth-profiling measurement that metallic Al diffuses into the cathode electrode, and that the fraction of oxidized Mg decreases gradually from the interface but extended very deep into the cathode.

Published: December 2018

Within recent years, the development of polymer-fullerene plastic solar cells has made significant progress. In such devices, an efficient charge generation takes place via photoinduced charge transfer between the photoexcited conjugated polymer and acceptor-type fullerene molecules. Due to the paramagnetic nature of the radical species, the photoinduced charge transfer can be studied by means of light induced electron spin resonance (LESR) techniques. We carried out W-band (95 GHz) LESR at high magnetic field strengths. Two well separated line groups with a strong anisotropic structure were detected for the composite MDMOPPV: PCBM. From the line shape analysis, we obtained an environmental axial symmetry for the positive polaron P+ and a lower, rhomboedric symmetry for the fullerene anion. The signals were found to be independent of each other with different spin-lattice relaxation times; hence, the radical species can be investigated separately. In order to study the bulk transport properties, we carried out admittance spectroscopy on the ITO/PEDOT:PSS/MDMO-PPV:PCBM/Al device. Two frequency-dependent contributions to the device capacitance with the activation energies 9 meV and 177 meV were found. For the very shallow trap state, we assume a bulk impurity, whereas the latter one is assigned to an interfacial defect state, located at the composite- aluminium interface.
Charge motion and trapping in molecularly doped hole transporters
Authors: Fong H.H. , Lun K.C. , So S.K.
Published: December 2018

The charge transporting properties of N, N'-dipheny l-N, N'-bis(3-methylphenyl)-(1,1'-biphenyl)-4,4'-diamine (TPD), TPD doped with 5,6,11,12- tetraphenylnaphthacene (rubrene), and TPD doped with 4-(dicyanomethylene)-2-methyl-6-(pdimethylaminostyryle) 4H-pyran (DCM1) were examined by time-of-flight (TOF) technique between 180-300K. The dependence of the mobility on electric field and temperature for undoped and doped TPD was investigated. Reductions in hole mobility shows that both dopants act as hole traps in TPD. Computational results of TPD also account for the effective hole conduction in pristine TPD film.

Authors: Borrós Salvador , Diago M.Paz , Esteve Joan , Agulló Núria
Published: December 2018

In this work, thin films (thickness ∼ 0.5 μm) were obtained by plasma polymerization of pyrrole (Ppy) and thiophene (Pth) at 25-30 W and 0.1-0.2 mbar of pressure. Further doping with iodine was carried out to some of the Ppy and Pth films (Ppy/I2, Pth/I2) in order to enhance their electrical conductivity properties.

Structural and morphological characterization of both Ppy and Pth as well as of Ppy/I2 and Pth/I2 was performed using Infrared Spectroscopy (IR), X-ray Photoelectron Spectroscopy (XPS) and Atomic Force Microscopy (AFM).

In the light of the information given by IR, XPS and AFM techniques, exhaustive and accurate description of both undoped and I2/doped Ppy and Pth films obtained by Plasma Polymerization is attained.

Authors: Tchoudakov Roza , Segal Ester , Narkis Moshe , Siegmann Arnon
Published: December 2018

Electrically conductive immiscible polymer blends containing high impact polystyrene (HIPS), liquid crystalline polymer (LCP) and a low content of conductive carbon black (CB) were studied to establish and understand the correlation between composition, electrical properties and the morphology of filaments produced at different melt flow conditions. The HIPS/LCP/CB blend containing 30% LCP and at least 2 phr CB reveals a stable resisitivity throughout the shear rate range applied in a capillary rheometer. Interesting structure alterations were observed for the LCP and CB components as a result of melt flow processing. Unusual sensing properties of liquids were found for the blends containing LCP.

Deus, a Bíblia e os evangélicos na Constituinte (1987-1988)
Authors: Melo Sydnei
Published: December 2018

A Assembleia Constituinte de 1987-1988 contou com uma participação, nunca antes vista, de um grande contingente de deputados de confissão cristã evangélica (protestantes e pentecostais), que foram reconhecidos enquanto uma “grande novidade” política para a época. O propósito deste artigo é evidenciar seu protagonismo em dois dos debates em que se envolveram: a defesa da presença regimental de um exemplar da Bíblia na Mesa da Assembleia Constituinte, e do registro da expressão “sob a proteção de Deus” no preâmbulo da Constituição. Argumentamos que, nas duas discussões, os parlamentares evangélicos sustentam suas posições como que amparadas em uma fé cristã majoritária no país, ao mesmo tempo em que faz de seus posicionamentos um registro de demanda política dos próprios evangélicos, afirmando sua colocação em uma disputa maior no interior do campo religioso.

Civilizing pirates: Nineteenth century British ideas about piracy, race and civilization in the Malay Archipelago
Authors: Eklöf Amirell Stefan
Published: December 2018

This article investigates how British officials and observers of the Malay Archipelago in the nineteenth century explained the prevalence of piracy in the region, particularly in terms of race and civilization. The writings by, among others, Thomas Stamford Raffles, John Crawfurd, James Brooke and Peter Benson Maxwell on contemporary Malay piracy are analysed. Whereas there was broad agreement among these observers that the alleged lack of civilization on the part of the Malays was a major reason for the prevalence of piracy in the region, there was considerable disagreement about the Malays’ capacity for civilizational progress and improvement. The degree to which the Malays were deemed capable of civilization in turn influenced the policies and measures implemented by the British to suppress piracy, ranging from the promotion of free trade to the wholesale extermination of entire villages and communities of suspected pirates. Criticism from humanitarians and liberals in London against the brutality of the latter tactics, however, led to a more restrained British deployment of violence in the Malay Archipelago from the middle of the nineteenth century.

Bør ledere være veiledere for nyutdannede lærere? En problematisering basert på teori om profesjonalitet og etisk bevissthet
Authors: Lejonberg Eli
Published: December 2018

Mange nyutdannede lærere i norsk skole har i dag lederen sin som veileder. At veilederansvar for nyutdannede lærere legges til lederrollen er blitt problematisert tidligere. Men hvorfor kan det være et problem at ledere er veiledere for nyutdannede? Er det fordi de mangler relevant kompetanse, eller er det andre forhold som gjør det problematisk å kombinere lederansvar med å være veileder for en nyutdannet lærer? I denne artikkelen belyses utfordringer knyttet til det å bruke nyutdannedes leder til veileder. Blant annet diskuteres hva profesjonalitet i veiledningsforhold i skolen innebærer. Spesielt fokuseres det på betydningen av etisk bevissthet for veiledere. Basert på teori om veilederes etiske forpliktelser overfor veisøkere problematiseres det å legge veilederansvar til ledere. Asymmetrien mellom ledere og veisøkere, og lederes makt og forpliktelser til andre aktører utenfor veiledningsforholdet kompliserer veiledningsforholdet. Det argumenteres for at nyutdannede har behov for veiledere som ikke også er ledere.
Studenters oppfatninger av god og dårlig praksisveiledning i barnehagelærerutdanning
Authors: Worum Kirsten S. , Bjørndal Cato R. P.
Published: December 2018

Formålet med artikkelen er å få innsikt i studenters oppfatninger av god og dårlig praksisveiledning i barnehagelærerutdanningen, noe som er avgjørende for å utvikle praksisveiledningens kvalitet. Studentperspektivet på praksisveiledningens kvalitet er lite fremtredende i nordisk forskning på barnehagelærerutdanning. Studien er basert på fire fokusgrupper, der studenter fra 1.-3. studieår i barnehagelæreutdanningen utveksler erfaringer og synspunkter på hva de oppfatter som god og mindre god praksisveiledning. Studentenes oppfatninger av kvalitet omfatter åtte aspekt; oppfølging av veilederen, veiledning tilpasset sitt behov, gode tilbakemeldinger, bli utfordret av veilederen, åpen dialog og gjensidig læring, veiledning sammen med andre men også alene, gode holdninger hos veilederen og godt samspill mellom praksis og campus. Funnene diskuteres i forhold til internasjonal forskning og diskursen mellom veiledningspedagogiske tradisjoner, og sees i lys av kvalitetsbegrepet i høyere utdanning med vekt på prosesskvalitet.

The purpose of this article is to gain insight into student-perceptions of supervision of practical training in kindergarten teacher-education. Today there is little Nordic research from the student-perspective on the quality of supervision of practical training in kindergartens. In this study students in their first, second, and third years of study, divided into four focus-groups, exchanged experiences and views on what they perceive as good and bad practical supervision. Students' perceptions of quality include; follow-up from the practical-training supervisor, supervision adapted to their needs, good feedback, being challenged by the supervisor, open dialogue and mutual learning, supervision along with others but also alone, good attitudes of the mentor, and good interaction between the practical placement and campus. The findings are discussed in relation to international research and the discourse between central Nordic schools of supervision. Findings are also seen in light of the concept of quality in higher education.
Nucleophosmin Phosphorylation as a Diagnostic and Therapeutic Target for Ischemic AKI

Published: December 2018

Background Ischemic AKI lacks a urinary marker for early diagnosis and an effective therapy. Differential nucleophosmin (NPM) phosphorylation is a potential early marker of ischemic renal cell injury and a therapeutic target.

Methods Differential NPM phosphorylation was assessed by mass spectrometry in NPM harvested from murine and human primary renal epithelial cells, fresh kidney tissue, and urine before and after ischemic injury. The biologic behavior and toxicity of NPM was assessed using phospho-NPM mutant proteins that either mimic stress-induced or normal NPM phosphorylation. Peptides designed to interfere with NPM function were used to explore NPM as a therapeutic target.

Results Within hours of stress, virtually identical phosphorylation changes were detected at distinct serine/threonine sites in NPM harvested from primary renal cells, tissue, and urine. A phosphomimic NPM protein that replicated phosphorylation under stress localized to the cytosol, formed monomers that interacted with Bax, a cell death protein, coaccumulated with Bax in isolated mitochondria, and significantly increased cell death after stress; wild-type NPM or a phosphomimic NPM with a normal phosphorylation configuration did not. Three renal targeted peptides designed to interfere with NPM at distinct functional sites significantly protected against cell death, and a single dose of one peptide administered several hours after ischemia that would be lethal in untreated mice significantly reduced AKI severity and improved survival.

Conclusions These findings establish phosphorylated NPM as a potential early marker of ischemic AKI that links early diagnosis with effective therapeutic interventions.
Missing: Understanding the Reception of a Serious Game by Analyzing App Store Data
Authors: Toftedahl Marcus , Backlund Per , Engström Henrik
Published: December 2018

The focus of this paper is the design and player reception of a serious game called Missing released on Google Play with the intention of spreading awareness of trafficking and its impact on individuals and society. The aim of the paper is to investigate how the game has been received by its players, focusing on its trafficking theme, by analyzing player metrics and app store data available from the Google Play digital distribution system. The paper presents results focusing on three main knowledge contributions: the identification and characterization of the tension between the designer’s intention with a game’s mechanics and how they help to convey the message of the game, the identification of the complexity of finding relevant reviews relating to the serious theme of the game and the identification and characterization of the tension between the star rating and the content of the reviews. One of the conclusions is that even a negative review can mirror a positive result in terms of fulfillment of the purpose.

Masculinidades en la industria del software en Argentina
Authors: Palermo Hernán M.
Published: December 2018

En el año 2017 iniciamos una investigación en empresas de procesos productivos vinculados con el software en Argentina. Algunos autores sostienen que las formas organizativas de trabajo caracterizadas como toyotistas o posfordistas encuentran su más acabada expresión en la industria del software. En este sentido, se postula la idea de una sociedad posindustrial a raíz de las tecnologías digitales. Otros, en cambio, plantean que nos encontramos inmersos en una nueva etapa denominada «capitalismo informacional». En el marco de esta industria, nuestro propósito para este artículo es indagar en las formas de construcción de un perfil de trabajador, retomando la premisa de que las políticas empresarias dinamizan nociones que configuran posiciones de género. En tal sentido, pretendemos desentrañar y problematizar la significación alrededor de las nociones de género en la industria del software, para comprender las estrategias de poder que se despliegan en estos espacios de trabajo donde las empresas son actores activos en la construcción de una hegemonía empresaria. Específicamente, nos interesa abordar la particular noción de masculinidad que se construye, dado que se trata de un trabajo en el que no hace falta el esfuerzo físico, la resistencia, la fortaleza, tal como sucede en otras actividades. Por el contrario, predomina una «cultura joven» siempre renovada y por momentos infantilizada. La vinculación profunda con la tecnología demanda «jóvenes talentosos», entendiendo que la idea de joven no se ancla unívocamente en la edad vital de un trabajador. En tal sentido, hallamos que en la industria de software no solo operan nociones no tradicionales acerca de la masculinidad, sino que podemos afirmar que la consolidación de una particular disciplina fabril fortalece una masculinidad no hegemónica, acorde a las necesidades del proceso de trabajo. Nuestra propuesta, en cierta forma rara avis, es situar la mirada en los trabajadores hombres en la industria del software y analizar la relación entre masculinidad y disciplina fabril.
Desigualdades de género en el Servicio de Ayuda a Domicilio: políticas, discursos y prácticas
Authors: Roca Escoda Mireia
Published: December 2018

A raíz de la aprobación de la Ley 39/2006, de 14 de diciembre, de Promoción de la Autonomía Personal y Atención a las personas en situación de dependencia, aumentó la promoción de servicios públicos de cuidados para hacer frente a las necesidades sociales; cosa que, por un lado, contribuyó a generar nuevas plazas de empleo, pero por el otro, ha convertido los cuidados en un sector ocupacional caracterizado por la feminización y la precariedad laboral, ya que se tienden a privatizar dichos servicios públicos, y las organizaciones privadas devienen las principales empleadoras del sector. Los estereotipos de género se reproducen en estos trabajos, donde las mujeres son las principales contratadas y los pocos hombres candidatos encuentran limitaciones para acceder a estas ocupaciones. En este artículo se analizan los discursos y prácticas de los agentes que operan en la gestión de los servicios de ayuda a domicilio (organizaciones y servicios sociales municipales), para conocer las barreras culturales y de oportunidad que dificultan la igualdad de género en estos servicios. La estrategia metodológica utilizada se basa en el análisis cualitativo de las entrevistas realizadas a los gestores del cuidado y de las observaciones en diferentes servicios públicos y organizaciones privadas.

Objetivou-se com este estudo testar o aumento linear da inclusão de glicerina bruta (86% de  pureza) em  substituição ao milho moído, como aditivo, na forragem de capim-elefante destinada a ensilagem, avaliando-se a qualidade nutricional do alimento e a viabilidade da ensilagem do material. Foram testados cinco níveis de substituição do milho pela glicerina em taxas que variaram de 3,12 a 12,5% sobre a matéria natural da forragem, além de um tratamento controle (apenas forragem). Realizaram-se análises bromatológicas e de digestibilidade para avaliar o valor nutricional da mistura durante a ensilagem e após o processo fermentativo, na silagem. Para avaliar a qualidade fermentativa foram feitas avaliações de pH, nitrogênio amoniacal, recuperação de matéria seca e densidade. A inclusão do milho moído incrementou (P<0,05) o teor de matéria seca em até 28%, tanto na forragem fresca, bem como na silagem. Tanto a inclusão do milho, bem como a substituição deste pela glicerina resultou (P<0,05) em um incremento médio de 25% e 32 % na digestibilidade in situ e valor energético da silagem, respectivamente quando comparado ao capim puro.  Isto, devido ao decréscimo (P<0,05) dos teores de fibra em detergente neutro e fibra em detergente ácido na silagem. A inclusão de glicerina aumentou (P<0,05) as perdas de proteína bruta durante a fermentação e diminuiu a recuperação da matéria seca. O teor de matéria seca da forragem parece ser fator chave para o sucesso de inclusão da glicerina como aditivo na ensilagem do capim-elefante, no intuito de evitar perdas expressivas de qualidade nutricional durante a fermentação.

Published: December 2018

The aim of the present study was to investigate selective separation and
preconcentration of Co(II) ions in aqueous solutions by ion imprinted
technique. For this purpose, Co(II)-methacryloylhistidine((MAH)2-Co(II))
complex monomer has been synthesized and polymerized with presence of
2-hydroxyethyl methacrylate (HEMA) followed by flushed out of bonded Co(II)
ions from polymer with 5.0 mol*L-1 HNO3. Thus, specific
cavities for re-binding of target ions (Co(II)) have been created onto
p-HEMA-MAH cryogel column. Prepared metal complex and Co-imprinted
polymer/cryogel system have been characterized by FTIR and SEM. The effect of
various parameters such as pH, initial concentration, flow rate, ionic strength
have been investigated to determine optimal adsorption conditions. The maximum
amount of adsorbed Co(II) has found as 106.0 mg*g-1 at pH 8.0 with
flow rate of 1 mL*min-1. For selectivity experiments, binding
studies were carried out presence of Cu(II) and Ni(II). The k (selectivity
coefficient) values have found as 8.9 and 3.8 for Co(II)/Cu(II) and
Co(II)/Ni(II) binary mixture, respectively. The reuse of column also has been
investigated and there was no significant decrease at adsorption capacity even
in consecutive eleven experiments.

Published: December 2018

Objective: The identification of risk factors for juvenile recidivism is crucial to prevent recurrent juvenile delinquency. The aim of the present study is to determine the variables that predict juvenile recidivism. In this regard, it is aimed to reveal predictive factors of juvenile recidivism by comparing one-time offenders with three and more time offenders.
Materials and Methods: In order to determine the factors that predict juvenile recidivism, data set derived through a retrospective analysis of social inquiry reports from Istanbul Child Court and Istanbul Child Criminal Court where adjudication held between 2005-2015. Social Inquiry Reports about at least three-time offenders (n=200) and one-time offenders (n=200) were examined. Data were classified into the main risk factors. Logistic regression analysis was used to determine risk factors that predict juvenile recidivism.
Results: It is found that risky peer groups, spend time in internet cafe, school dropout have most significant prediction on juvenile recidivism. In addition, it is also found that number of siblings, age in the first delinquent behavior, weakness of familial sharing and communication and drug abuse have significant effect on juvenile recidivism.
Conclusion: It is understood that juveniles who are between the age of 12-15, being one-time offender, having risky peer group, spending most of the time in internet cafe, and dropped out of the school most likely turned into recidivist. It is important for the protection of the child, as well as for the community, that the family, community and authorities should take the necessary precautions to ensure that the...

L’autore analizza, in una prospettiva evolutiva, il vincolo di forma nei licenziamenti. Vengono in primo luogo esaminate le conseguenze della mancanza di forma scritta del licenziamento per distinguerla dalla mancata indicazione dei motivi, oggi distinti anche sotto il profilo sanzionatorio come ipotizzato in passato da attenta dottrina. Esaminate quindi le procedure previste per il licenziamento per giustificato motivo oggettivo e giusta causa, l’autore verifica la procedura dei licenziamenti collettivi di matrice europea e le modificazioni introdotte dalle riforme del 2012 e del 2015, evidenziando le problematiche connesse al depotenziamento dei vincoli forma.The author analyzes, in an evolutionary perspective, the obligation of the form in dismissals. Firstly, the consequences of the absence of a written form of dismissal are examined to distinguish them from the lack of reasons indication, which are presently distinct from the point of view of sanctions, as it has been hypothesized in the past by careful interpretation. After examining the procedures for dismissals for economic and disciplinary reasons, the author checks the procedure of collective redundancies of European origin, and the changes introduced by the reforms of 2012 and 2015, highlighting the problems related to the weakening of the form.El autor analiza, en una perspectiva evolutiva, la restricción de la forma en los despidos.

Traditional harvesting methods of NTFP are known to be destructive and/or wasteful that can reduce and sometimes deplete the population of NTFP and the biological diversity. Sustainable harvesting is not only necessary for conservation of plant diversity, but also for the livelihoods of many rural peoples in forest areas who rely on forest products for their sustenance. Sustainable harvesting increasingly acknowledged as a conservation strategy can easily be employed for species plants that require seeds harvest as product, such as Griffonia and Xylopia. The harvest of such NTFP requires a practical sustainable harvesting method and a change of behavior pattern towards sustainability. Change in behavior patterns with corresponding modifications in harvesting techniques can create a win-win strategy for harvesters and the biodiversity. The study describes current methods for harvesting two important Liberian NTFP (Griffonia simplicifoliaandXylopia aethiopica) and suggested alternative (proposed sustainable) technique and their impact on the population in two harvesting seasons. In the first and second harvest seasons, using traditional methods, an average total of 34.6kg of Xylopia and 22.7kg of Griffonia was collected; while using alternative methods, an average total of 52.5kg of Xylopia and 34.7kg of Griffonia collected. Equally using the traditional method, an average total of 87 trees of Xylopia were damaged, while an average total of 12 trees were damaged using the ‘proposed sustainable’ method. Changes in behavior pattern of local collectors incorporating the ‘proposed sustainable’ technique of collection lead towards a win-win situation for NTFP with added value of preservation.

Published: December 2018

Kombucha is made from sweetened tea fermented by a symbiotic culture of bacteria and yeast consumed worldwide because of its potentially beneficial effects on health. However, there are only few studies on the safety of kombucha consumption that will establish it as a functional beverage. The present study compared, pH, temperature and sugar content of different tea mixtures of black or green tea as nitrogen sources and white and brown sugar as carbon sources in a 30-day fermentation period. A marked decrease in pH was observed throughout fermentation with Green tea-White (GW) sugar mixture showing the lowest recorded pH value of 2.37 on the 14th day of fermentation. Temperature is essential in the fermentation process and thus maintained at ambient 29±1°C. Black and green teas with white sugar (7°Brix) showed to have higher sugar level compared to tea mixtures with brown sugar (5°Brix). Brine Shrimp Lethality Assay was carried out to determine cytotoxicity of kombucha. The four substrate combinations have very low LC50 values with Black tea-Brown sugar (BB) mixture showing to have the lowest in both acute and chronic effects (0.073 ppm and 0.101 ppm, respectively). This indicates safety of kombucha for consumption.

Over 70 % inhabitants of Imo state pend on palm oil for their cooking, frying etc. The study reviews available data on palm oil quality produced locally in Imo state with a view of providing up-to-date information and identify research gaps that could have health consequences on consumers. Peer reviewed scientific articles were reviewed and a meta-analysis of four different scientific research databases, PubMed, Web of Science, Google Scholar and Directory for Open-Access Journals was conducted. The result showed that palm oil produced locally in Imo state has average of pH (4.73), acid value (28.3 mg/KOH), FFA (14.15 mg/KOH), smoke point (115°C), iodine value (1.68 wijj’s), saponification value (197.07 mgKOH/g), ester value (168.77), moisture content (0.44 %), density (0.89 g/ml), SG (0.91), peroxide value (17.75 mEq./kg), refractive index (1.46oBx) and viscocity (60.04 cps). Overall palm oil is highly degraded and of poor quality since major quality indicators are not within Nigerian Industrial Standard and Standard Organization of Nigeria. Also, there is a dearth of information/data available on quality of palm oil produced locally in Imo state especially on its microbial status. Food scientist should look in that direction to enhance proper understanding of the quality of palm oil.

The article presents an analysis of the possibility of using propulsion systems and rocket thrusters based on various physical principles and used as part of small and very small spacecraft. The parameters of efficient propulsion systems and low-thrust rocket engines are examined from the standpoint of being used as components of spacecraft fueled by various kinds of propellant: gaseous fuel, mono-fuel, including advanced compositions based on hydroxyl-ammonium nitrate, bipropellant fuel; xenon electric rocket systems, as well as special propulsion systems and low-thrust rocket engines operating on nitrous oxide, ammonia, gaseous hydrogen and oxygen; electric-powered systems based on pulsed plasma thrusters, ion and steady-state plasma engines. Taking into account the data analyzed, an attempt was made to categorize the propulsion systems and low-thrust rocket engines. Their use in small spacecraft, spacecraft of the Mini, Micro, Nano classes in various propulsion systems and low-thrust rocket engines was found to be preferable.

Published: December 2018

A new method is proposed for coating the inner surface of pipes in a confined space in which a sloping position of the pipe is expected during the process. Mathematical modeling of non-pressure fluid flow in an inclined pipe was carried out. The method implies controlled outflow of the material being applied and simultaneous rotation of the pipe being worked. The thickness of the coating depends on the velocity of the material flow along the inner surface of the pipe. The dependence of the fluid velocity on the radius of the pipe being worked and the level height in the filling column is calculated. The results of calculating the analytical dependence in the Mathcad application are presented. Dependence diagrams of material flow are presented for various design parameters that make it possible to determine the operating practices in the process of applying the coating. Uniform coating is obtained due to constant velocity of the material flow along the full length of the pipe. The obtained graphs were analyzed and the direction of further research connected with the influence of rotational velocity and fluid viscosity was determined. The use of the proposed method makes it possible to increase labor productivity and improve the quality of protective coating.

Published: December 2018

The article examines the issues of determining the light-and-shadow situation and its impact on providing energy balance on the orbits of two small satellites of the AIST series. Ensuring energy balance in the operation of mission equipment becomes particularly relevant in the case of power limitations caused by both the degradation of spacecraft systems and the factors of outer space. The main purpose of the article is to solve the problem of increasing the efficiency of the power supply system of AIST-series small satellites operating under resource constraints. Firstly, modeling of the lighting situation on the orbits of small satellites was carried out. Secondly, the telemetric information of AIST small satellites for the whole period of operation was examined. In addition, the influence of the light-and-shadow conditions on the parameters of the power system of a small satellite was analyzed. As a result, an algorithm for estimating the energy balance, taking into account the influence of the light-and-shadow situation was proposed. Using the proposed algorithm made it possible to take into account the influence of seasonal variations in the light-and-shadow environment on the possibility of ensuring energy balance in the operation of mission equipment

Published: December 2018

Trata-se de uma revisão de a literatura acerca do desempenho clínico do cimento de ionômero de vidro (CIV) utilizado no tratamento restaurador atraumático (TRA). Realizaram-se buscas nas bases de dados: Biblioteca Virtual em Saúde Odontologia, Medline, Pubmed e Science Direct, utilizando os descritores “cimentos de ionômeros de vidro”, “tratamento dentário restaurador sem trauma” e “análise de sobrevida”, bem como os respectivos termos em inglês. Foram selecionados 23 artigos nos idiomas português e inglês, publicados nos últimos dez anos, seguindo critérios de inclusão e exclusão pré-determinados. Percebeu-se que a maioria dos estudos aplicou o TRA em crianças (66%), direcionado à dentição decídua (57%) e em cavidades de superfície única e múltipla (48%), simultaneamente. A maioria dos estudos acompanhou o desempenho clínico das restaurações no período de 12 (35%) e 24 meses (35%). O CIV de alta viscosidade foi mais utilizado e as marcas Fuji IX e Ketac Molar foram as mais empregadas no TRA. Concluiu-se que O CIV associado ao TRA demonstra ser uma alternativa viável para tratar cárie em dentes decíduos e permanentes. A longo prazo, o CIV apresenta desempenho superior em cavidades de superfície única em relação às multisuperfície. De modo geral, as taxas de sucesso das restaurações oscilaram entre: 57,5 e 98%, em superfícies únicas, e 24,4 e 97,8%, em superfícies múltiplas. Esta abordagem mostrou ser confiável e efetiva quando comparada a técnica restauradora convencional. O defeito marginal e a perda parcial ou total da restauração foram identificados como principais causas de falha.
