An update on non-surgical management of periodontal diseases
Authors: Midwood Imogen , Hodge Penny
Published: November 2019

Non-surgical periodontal therapy (NSPT) underpins all other restorative treatment which takes place in the mouth. Therefore a thorough understanding of the process of delivery of effective NSPT and long-term maintenance of periodontal health is essential for every dental practitioner. This article covers the steps involved and discusses the benefits and challenges which may be encountered.

CPD/Clinical Relevance: This article highlights the benefits and challenges of non-surgical management of periodontal disease and the key role that the patient plays in achieving and maintaining periodontal health.
The role of maintenance in periodontal disease
Authors: Batt Joanna , Ower Phil , Sharma Praveen
Published: November 2019

There is increasing recognition, made explicit in the new classification for periodontitis, that periodontitis is a lifelong disease that is not ‘cured’ but rather ‘managed’. This paper focuses on how the response to periodontal treatment is ideally measured and how decisions are made as to whether the treatment has been ‘successful’ or not. The roles of both the patient and practitioner in the maintenance of periodontal health for those patients who respond to initial therapy are crucial. Patients not responding to initial, non-surgical periodontal therapy also need to be appropriately managed, as outlined in this paper.

CPD/Clinical Relevance: This paper highlights the importance of maintenance of periodontal health, as an integral part of the overall management of patients with periodontitis, in order to minimize further periodontal breakdown and eventual tooth loss.

Authors: Daly Alex , McCracken Giles
Published: November 2019

Where suitable, dental implants are praised as a method of providing fixed solutions with good longevity, and providing greatly improved retention for removable prostheses, resulting in increased levels of patient satisfaction and quality of life.

However, with increasing evidence of long-term follow-up, there is a growing recognition of the susceptibility of dental implants to peri-implant diseases; peri-mucositis and peri-implantitis. This paper discusses the features of peri-implant disease and important aspects of assessment criteria.

CPD/Clinical Relevance: This paper highlights the importance of supportive maintenance care for patients with dental implants, as well as the features and assessment of peri-implant disease.

Comparison of sterile polyacrylate wound dressing with activated carbon cloth and a standard non-adhesive hydrocellular foam dressing with silver: a randomised controlled trial protocol
Authors: Probst Sebastian , Saini Camille , Skinner Monika Buehrer
Published: November 2019

Objective:

Hard-to-heal wounds such as leg (LU) or diabetic foot ulcers (DFU) are slow healing, have a high recurrence rate and are associated with infection, smell and exudate. Current therapeutic approaches are multifaceted and focus on improving wound healing and preventing recurrences. Advanced wound dressings, especially super absorbent dressings are an important aspect of wound care, as hard-to-heal wounds tend to produce excessive amounts of exudate, which may contribute to maceration and excoriation, thus delaying wound healing. Additionally, excessive wound exudate is associated with malodour. Therefore, an important aspect of care is the management of exudate and odour. The use of effective advanced wound dressings is a promising strategy to achieve adequate absorption of wound exudate and malodour promoting wound healing. The aim of the current study is to determine whether there is a difference in wound size reduction between wounds dressed with either a sterile polyacrylate wound dressing with activated carbon cloth or a hydrocellular foam dressing with silver.

Method:

A randomised controlled trial with 248 participants in one wound care outpatient clinic is proposed. Randomisation will be concealed. The outcome assessor will be blinded to the group allocation of participants.

Conclusion:

This research project compares two wound dressings in an everyday care setting. Since the cost of hard-to-heal wounds to individuals, the economy and society is high, an evaluation of which wound dressing leads to a faster reduction of wound size and subsequent wound healing is an important issue/question for the individuals affected, their families, society and the health-care system.
Communication with patients using negative wound pressure therapy and their adherence to treatment
Authors: Moffatt Christine J. , Murray Susie , Aubeeluck Aimee , Quere Isabelle
Published: November 2019

Objective:

The purpose of this study was to explore the challenges of communication between patients and health professionals, and patient adherence to treatment for hard-to-heal wounds when using negative wound pressure therapy (NPWT).

Methods:

Face-to-face, semi-structured interviews were conducted with patients undergoing NPWT. Specific features of the NPWT device were the priority for discussion although other factors central to communication and adherence were also explored.

Results:

A total of 24 patients took part in the study. Data saturation was achieved during the analysis. Patients required ongoing support to understand complex and often protracted treatment and this was particularly important when specialist technology was used. A distinction was highlighted between those who decided not to adhere with therapy and those who did so unintentionally. Participants faced difficulties in their communications with health professionals and in ensuring their needs were listened to and addressed.

Conclusion:

Further research is needed to achieve a better understanding of this distinction and to evaluate interventions which can sustain adherence behaviours. Further exploration of how to establish concordant patient/health professional communications is warranted.
Measurement of mechanical withdrawal threshold on full-thickness cutaneous wounds in rats using the von Frey test
Authors: Goto Taichi , Nakagami Gojiro , Minematsu Takeo , Shinoda Masamichi , Sanada Hiromi
Published: November 2019

Objective:

A method for measuring mechanical withdrawal threshold of full-thickness cutaneous wound pain in animal models is lacking. This study aimed to confirm the validity and reactivity of the von Frey test in full-thickness cutaneous wounds in rats.

Method:

A 1.5cm-diameter wound was established on the dorsal areas of male Sprague-Dawley rats and subcutaneously injected with either morphine hydrochloride (5.0mg/kg) or indomethacin (2.5mg/kg) with a 27-gauge needle on day three post-wounding. On day five post-wounding, an injection of morphine hydrochloride, indomethacin or lambda-carrageenan (1.0%) into the granulation tissue was also administered. The withdrawal threshold of mechanical stimulation of the wound edge was compared in each group before treatment with injection and at two, four, eight and 24 hours after injection.

Results:

A total of 40 rats were used in the study. Since more severe inflammation in and around the wound was induced on day three post-wounding than that of day five, the withdrawal threshold measured on day three post-wounding was significantly lower than that of day five. The decrease of the withdrawal threshold was depressed by morphine hydrochloride and indomethacin treatment on day three post-wounding. While there was no significant difference between the changes in the withdrawal threshold after indomethacin treatment on day five post-wounding, we observed an increased withdrawal threshold after morphine hydrochloride treatment and decreased withdrawal threshold after lambda-carrageenan treatment on day five post-wounding.

Conclusion:

The results suggest that the von Frey test can be applied to measure the mechanical withdrawal threshold of full-thickness dorsal wounds in rats.

Published: November 2019

Highlights

The atomizer droplet size should be considered an important factor when designing aeroponic systems.

Airless atomizers had significant positive effects on plant growth, total polyphenol content, and antioxidant activity.

Airless atomizers and a spraying interval of 20 min on and 3 h off was the best combination for lettuce plants.

Abstract. Throughout our literature review, the effects of various aeroponic atomizers (droplet sizes) on specific leafy plant growth and quality were minimally reported. Lettuce ( L.) is one of the most popular leafy vegetables consumed around the world. The present study sought to determine the effects of various aeroponic atomizers (droplet sizes) on the growth, total polyphenol content, and antioxidant activity of lettuce plants. Aeroponic systems were designed and manufactured using three kinds of atomizers: air-based (A1), airless (A2), and ultrasonic fogger (A3). The South China Agricultural leafy vegetable B nutrient solution was selected as the cultivating solution. Additionally, the spraying time and spraying interval were set at 20 min on and 3 h off. The sizes of the droplets generated by these atomizers were measured using a laser particle size analyzer, and the measured average droplet sizes generated by the A1, A2, and A3 atomizers were 23.281, 46.386, and 3.451 µm, respectively. The results showed that the lettuce plants treated with the A2 atomizers exhibited more significant effects on the growth, total polyphenol content, and antioxidant activity of the lettuce compared to those treated with the A1 and A3 atomizers. The results indicated that nutrient solution droplet size should be considered an essential factor when designing an aeroponic system. Keywords: Aeroponic, Antioxidant activity, Soilless, Spraying time, Total polyphenol content.

Published: November 2019

Highlights

The rice dust collection performance of bag filters was investigated.

The pressure drop and rice dust collection efficiency were measured with various parameters.

Correlation equations are suggested for the pressure drop across a clean filter medium and across the dust cake.

Abstract. Because rice dust constitutes a form of air pollution, bag filters are widely used in rice processing facilities. Rice dust has various particle sizes, and the dust concentration in air is low with rice dust. Research on the rice dust collection performance of bag filters is necessary for effective dust collection in rice processing facilities. The objective of this study was to investigate the rice dust collection performance of bag filters. The pressure drop and rice dust collection efficiency were measured with various face velocities, dust concentrations, and fabric filter media. The dust collection efficiency decreased slightly with increases in the face velocity and in the maximum pressure drop in normal conditions. In addition, correlation equations of the pressure drop across a clean filter medium and across the dust cake are suggested to predict the pressure drop in overloaded conditions in rice processing facilities. The average error was 20.2%, and it decreased with increasing pressure drop. Using the correlation equations, bag filters can be managed to remove the deposited dust before the pressure drop significantly increases or reaches its maximum value. Keywords: Bag filter, Dust collection efficiency, Pressure drop, Rice dust.
Application of immunofluorescence assay and nested polymerase chain reaction for query fever diagnosis in animal handlers of Puducherry, South India, and phylogenetic analysis based on IS1111 repetitive gene element
Authors: Pradeep Jothimani , Stephen Selvaraj , Sangeetha Balakrishnan , Antony Prabakar Xavier , Amsaveni S. , Pooja Pratheesh
Published: November 2019

Background and Aim: Diagnosis of query fever (QF) is mostly done on the basis of serological/molecular tests, due to the stringent requirement of biosafety level-3 containment facilities for isolating Coxiella burnetii in culture. QF is an important zoonosis and is considered to be an occupational hazard to livestock handlers. This report describes our study on the serological as well as molecular evidence of QF in animal handlers from Puducherry and surrounding Tamil Nadu, from where, to the best of our knowledge, no such reports are available so far. Materials and Methods: Seventy-five animal handlers were recruited, comprising veterinarians, slaughterhouse workers, butchers, and animal attendants of various government veterinary clinics from Puducherry and surrounding areas of Tamil Nadu state. QF serology was performed to identify Phase I and Phase II immunoglobulin G antibodies to C. burnetii. Nested polymerase chain reaction (N-PCR) was carried out to detect C. burnetii DNA in buffy coat samples by targeting IS1111 gene element. N-PCR-positive samples were sequenced and phylogenetic analysis was performed using MEGA software version 10.0. Results: A total of 21 animal handlers (28.1%) were positive for either serology or PCR. PCR alone was positive in 10 (13.4%), only serology was positive in 8 (10.7%), and both serology and PCR were positive in three samples (4.0%). GenBank accession numbers were obtained for 13 N-PCR-positive samples (MG548608-MG548620). Six of our study sequences showed close similarity with the reference isolates from Bengaluru, Colombia, Brazil, France, and Iran. Conclusion: A significant percentage of QF positivity in animal handlers of this part of South India, Puducherry, warrants a prospective study with follow-up of a large number of this occupational group.
Influência da velocidade de carregamento e temperatura no comportamento mecânico de misturas recicladas a frio com emulsão asfáltica e espuma de asfalto

Published: November 2019

A reciclagem a frio de pavimentos é uma alternativa sustentável para a redução do consumo de materiais virgens e do descarte inadequado de resíduos gerados em obras de restauração. Entretanto, ainda não há um consenso sobre as propriedades mecânicas das misturas recicladas a frio, principalmente em relação ao comportamento viscoelástico. Por meio de simulações computacionais usando o software 3D-Move Analysis, avaliou-se a influência que a velocidade dos veículos e a temperatura de trabalho têm sobre as propriedades mecânicas de um pavimento cujas camadas de base são constituídas por misturas recicladas a frio estabilizadas com emulsão asfáltica (AEM) ou com espuma de asfalto (FAM). Com o objetivo de estudar como variam as deformações longitudinais para um ponto localizado no fundo do revestimento asfáltico, observou-se que os materiais reciclados a frio apresentam comportamento viscoelástico, pois diferentes combinações de velocidade e de temperatura resultam em diferentes distribuições de tensão e deformação na camada de revestimento. Dessa forma, observou-se que a não consideração da presença de viscoelasticidade linear para estes materiais pode vir a subestimar a capacidade de suporte da estrutura.

COMPENSATION OF SPRINGBACK IN LARGE SHEET METAL FORMING
Authors: Pačák Tomáš , Tatíček František , Valeš Michal
Published: November 2019

A precise production of sheet metal parts has always been a main goal in press shops. Highest quality demands are required especially in automotive production. Unfortunately, even today, the production is not optimal due to an ineffective approach to the springback compensation. Springback results in geometrical shape inaccuracies of the obtained product. Based on the current approach, excessive time and financial costs emerge due to corrections on the press tools. However, these corrections do not always lead to a better accuracy of the stampings. The main objective of the research is to design a modified solution of the current approach. The modified solution is designed as a methodology with a focus on the analysis and compensation of the springback with a help of a numerical simulation. To achieve the main goal, smaller sub-goals are employed. These sub-goals, or rather experiments, mainly focus on parameters, which, more or less, influence the springback phenomenon. The designed methodology is verified with real car body parts and is carried out with a help of the department of the press tools design in ŠKODA AUTO, a.s. There, the methodology is used for improving the accuracy of the stamping process of the car body parts and for improving the quality of the final product.

Multiplicity and concentration results for magnetic relativistic Schrödinger equations
Authors: Xia Aliang
Published: November 2019

In this paper, we consider the following magnetic pseudo-relativistic Schrödinger equation

$$\begin{array}{}
\displaystyle
\sqrt{\left(\frac{\varepsilon}{i}\nabla-A(x)\right)^2+m^2}u+V(x)u= f(|u|)u \quad {\rm in}\,\,\mathbb{R}^N,
\end{array}$$

where ε > 0 is a parameter, m > 0, N ≥ 1, V : ℝN → ℝ is a continuous scalar potential satisfies V(x) ≥ − V0 > − m for any x ∈ ℝN and f : ℝN → ℝ is a continuous function. Under a local condition imposed on the potential V, we discuss the number of nontrivial solutions with the topology of the set where the potential attains its minimum. We proof our results via variational methods, penalization techniques and Ljusternik-Schnirelmann theory.
Regularity Properties for a Class of Non-uniformly Elliptic Isaacs Operators
Authors: Ferrari Fausto , Vitolo Antonio
Published: November 2019

We consider the elliptic differential operator defined as the sum of the minimum and the maximum eigenvalue of the Hessian matrix, which can be viewed as a degenerate elliptic Isaacs operator, in dimension larger than two. Despite of nonlinearity, degeneracy, non-concavity and non-convexity, such an operator generally enjoys the qualitative properties of the Laplace operator, as for instance maximum and comparison principles, ABP and Harnack inequalities, Liouville theorems for subsolutions or supersolutions. Existence and uniqueness for the Dirichlet problem are also proved as well as local and global Hölder estimates for viscosity solutions. All results are discussed for a more general class of weighted partial trace operators.
Cracking wise to break the ice: The potential for racial humor to ease interracial anxiety
Authors: Borgella Alex M. , Howard Simon , Maddox Keith B.
Published: November 2019

We explore the idea that humor focused on social group disparities can be a viable tool to reduce some of the negative outcomes associated with interracial interactions. These interactions are crucial in promoting common understanding about the causes of social, educational, and economic disparities and crafting solutions to redress them. However, investigations have demonstrated that interracial interactions can be emotionally and cognitively taxing, and for these reasons are often avoided. When not avoided, these interactions often result in negative outcomes. Anxiety has been identified as a key factor in these outcomes as majority group members cope with concerns over appearing biased and minority group members cope with concerns over being discriminated against. Humor may be able to alleviate anxiety that contributes to negative outcomes associated with intergroup dialogue. To explore this claim, we first review the literature on interracial interactions and the role of anxiety in shaping them. We then discuss investigations exploring the impact of group-related humor, specifically disparagement humor, on intergroup perceptions. Finally, we draw from both literatures to consider factors that might determine race-related humor’s potential to facilitate positive interracial dialogue through anxiety reduction. We conclude with some possible areas for further research.
Neo-Gricean perspective on irony, deception, and humor vs. some insights from experimental studies
Authors: Piskorska Agnieszka
Published: November 2019

This article discusses a neo-Gricean approach to irony, deception and humor developed by Marta Dynel, confronting some of its assumptions and implications with results of experimental research. It is stated that Dynel’s modifications and elaborations of Grice’s original theory of conversation improve its coherence and provide adequate methodological tools for a comprehensive model of irony, deception and humor in multi-party interactions, and also for teasing out subtypes of each of these phenomena. Questions regarding the compatibility of this model with experimental findings concern such issues as the relation of irony and deception to Theory of Mind, and the impact of “humor for humor’s sake” on hearers’ opinions. Although these issues are not addressed in Dynel’s philosophically-oriented framework, they are not necessarily incongruent with her perspective.
Diet selection and habitat use by the mountain vizcacha (Lagidium viscacia) in the Southern Andean Precordillera (Argentina)
Authors: Puig Silvia , Rosi María I. , Videla Fernando , Seitz Viviana P.
Published: November 2019

Lagidium viscacia is considered as a fragile species with patchy distribution, a strict habitat specialist and an obligatory diet specialist. The Southern Andean Precordillera constitutes an interesting environment to analyze the species’ presence across the altitudinal gradient. Diet selection and habitat use were studied in the summit plateau, characterized by rigorous conditions and vegetation representative of the Southern Puna. Pellet groups were counted in transects perpendicular to rock formations, and diet and vegetation were seasonally analyzed using microhistological analysis and point-quadrat transects. Vizcachas were strictly associated with rock formations at middle and high altitudes, with higher occurrence on the mountain summit where grasslands surrounded the rock formations. Vizcachas avoided shrubs associated with rock formations and preferred grasses on sandy soils. Phenological changes slightly affected the selective diet that involves a considerable search effort and risky feeding activity. Puna grasslands constituted attractive feeding places where L. viscacia’s activity decreased with distance from rock shelters as expected for a central-place forager. Habitat partitioning allows coexistence with Ctenomys mendocinus, despite the high dietary overlap between these central-place species. The high mobility and broad diet of Lama guanicoe reduce the competition risk. Lepus europaeus preferred shrubs and forbs, determining a discrete dietary overlap with vizcachas.

Published: November 2019

Small mammal communities in the Neotropics are composed largely of sigmodontine rodents. However, many questions regarding these communities remain unanswered, especially those pertaining to fine-scale sympatry and habitat selection. To address this, we examined sigmodontine community structure and vegetation in the western margin of the Upper Paraná Atlantic Forest and the southwestern-most extent of the Cerrado (CE) (an extensive South American savanna ecoregion) of Paraguay. Vegetation classifications were derived from satellite imagery combined with maps based on extensive ground-based surveys. The three most abundant species (Akodon montensis, Hylaeamys megacephalus, and Oligoryzomys nigripes) were found most often in microsympatry with conspecifics, and were negatively associated with other species. Akodon montensis was associated with high forest (HF), and H. megacephalus with bamboo understory (BU), whereas O. nigripes did not exhibit a habitat preference. The first two species’ distributions within the landscape were found to be driven primarily by habitat selection, and O. nigripes by a behavioral response (avoidance) to the presence of the other two species. Moreover, habitat influences whether or not a particular species associates with, or avoids, conspecifics or other species.

Published: November 2019

The use of fiber-metal laminates (FML) allows for substantial advantages over a fuselage skin made of monolithic aluminum materials. Glass fiber prepreg reinforced aluminium is characterized by high damage tolerance capabilities, supporting the structural strength capability in case of any kind of damage. For this reason, FML, and GLARE in particular, have been identified as superior materials for aerospace applications. More than 400m2 FML is applied on each A380, as skin panels and as D-noses for both, vertical and horizontal stabilizer. FML possess the potential to become the baseline material for next-generation single-aisle aircrafts [1, 2, 6].

The development of a new production chain that will allow automated fuselage production for future short-haul aircrafts is the focus of the studies that make up the joint project AUTOGLARE. As part of the fifth call-up for the German Aeronautical Research Programme (LuFo), the German Aerospace Center (DLR) is working with its project partners Airbus Operations, Premium Aerotech (PAG) and the Fraunhofer Gesellschaft (FhG). The development of a production chain for stiffened fuselage panels made of Fiber metal Laminates should support a production rate of 60 aircraft per month [3].

This study contains the research work of the DLR and FhG regarding the automated and quality assured process for chain stiffened FML fuselages. In addition to a detailed explanation of the systems that were set up, this paper covers the planned tests, the completed demonstration models and the findings derived from them.
Nanofluidic Behavior at the Fluid-Solid Interface
Authors: Chen Yan , Yue Yuan , Rasoulzadeh Mojdeh , Liang Hong
Published: November 2019

The confinement and nature of complexity at the fluid-solid interface pose significant challenges for studying the nanofluidic behavior. Here, we report an approach to probe the rheological performance of three media through dynamic interaction with a harmonic oscillator. A prototype device is developed that is able to vibrate in the range up to hundreds of hertz. Results show that the interfacial viscosity was similar to that of its bulk in terms of amplitude and frequency. However, an additional phase lag appeared when the amplitude was small, and its responsive curve exhibited distortion around the natural frequency. Theoretical analysis indicated that this might be due to fluid memory because the fluid response to the solid motion is not instantaneous. The approach reported here has potential to lead toward new ways of studying dynamic properties of fluid-solid interfaces.

El presente trabajo se centra en el estudio de la agravante genérica por “razones de género” (art. 22.4 del CP); circunstancia modificativa incorporada a nuestro Código Penal mediante la LO 1/2015, de 30 de marzo. Se analizan, en primer lugar, las causas que motivan su introducción en nuestra normativa penal, y se efectúa una aproximación al fundamento de la agravante. Posteriormente, se trata la diferencia entre la agravante de sexo y la de género, y se prosigue con el análisis de los preceptos a los que podría ser de aplicación la circunstancia agravante, tomando en consideración para ello el principio de inherencia. Se introducen asimismo determinadas referencias jurisprudenciales al respecto. Se concluye indicando que la agravante de género constituye una aportación novedosa en nuestra normativa, sin que esté destinada a cumplir una mera función simbólica.
Una reconstrucción de la idea de Sutherland de patrones y procesos delictivos a partir del primer Durkheim
Authors: Serrano Maíllo Alfonso
Published: November 2019

La idea de patrones y procesos delictivos fue propuesta por SUTHERLAND, si bien no definió muy bien estos conceptos ni la relación que existe entre ellos. En esta obra afrontamos este reto partiendo del trabajo de DURKHEIM. De acuerdo con el mismo, una serie de procesos determinan la celebración de y la participación en interacciones o ritos; éstos hacen nacer determinados patrones; finalmente, algunos de éstos gozan de fuerza causal y de este modo influyen en los procesos. Los patrones estructurales se estudian a partir de la concepción durkheimiana de solidaridad mecánica y orgánica que aparece fundamentalmente en el libro La división del trabajo social (1893). Patrones estructurales relevantes para la distribución del delito son la urbanización, la desigualdad o los ciclos económicos, por citar unos pocos ejemplos.

Published: November 2019

The molybdenum disulfide (MoS2) and indium tin oxide (ITO) interface were studied by atom probe tomography (APT). Raman spectroscopy, scanning electron microscopy, and grazing-incidence x-ray diffraction measurements were performed as complementary characterization. Results confirm that nanowires plated shape with the 〈110〉-orientation are aligned perpendicular to the ITO film with principal reflections at (002), (100), (101), (201), and Raman spectroscopy vibrational modes at E12 g at 378 cm−1 and A1g at 407 cm−1 correspond to 2H-MoS2. APT reveals MoS+2, MoS+3 as predominant evaporated molecular ions on the sample, indicating no significant diffusion/segregation of Mo or S species within the ITO layer.

La educación desde las vertientes de la teoría crítica.

Published: November 2019

El hombre, en la actualidad, es producto de la educación que se le imparte, puesto que su comportamiento responde a las corrientes de pensamiento filosófico e ideológico que determinan su vida según el paradigma y concepción predominante para el momento que vive, determinándolo de esta manera como proyecto, razón por la cual la educación posee la responsabilidad de organizar los saberes que le aportan a la sociedad para direccionar su existencia, de allí que sea la Teoría Crítica, según los aportes de sus teóricos quienes desde un punto de vista crítico, sea la llamada a emancipar al hombre, tal como se observa dentro de sus teorías, reconociendo que los hallazgos hechos por toda Europa encuentran mucha opresión dentro del desarrollo social que se vivió en la época de los Nazis, quienes en su afán de poder se extralimitaron con el trato a sus congéneres, al devastar todo un país y, como tal, una sociedad; de manera que para lograr un cambio se hizo necesario prestar atención a lo aportado por Herbert Marcuse en su obra “El Hombre Unidimensional” y Theodor Adorno en su trabajo “Educación para la Emancipación”, trabajos que invitan al hombre a cambiar de vida y seguir sus propias particularidades, teorías que en la actualidad tienen vigencia si se observa que siguen existiendo paradigmas y concepciones que guían la existencia del ser humano en sociedad y si se presta atención a éstas se puede mejorar la existencia del hombre en su entorno, pues solo el conocimiento del pasado le ayuda a mejorar el presente, así como el uso de la Teoría Fundamentada es útil para comprender mejor la Teoría Crítica que lo lleve a una conceptualización profunda que le ayude a liberarse de un futuro opresor.

Abstract Knowledge of the genetic variability among genotypes of bushy cashew is important to establish strategies for pre-breeding and use in breeding program. The objective of this study was to evaluate the genetic diversity of bushy cashew by means of the evaluation of physical, chemical and physicochemical characteristics of cashew apples and cashew nuts. The work was carried out with cashew nuts and cashew apples collected in the harvest of 2016 of genotypes in the “ex situ” biological collection of Anacardium humile A. St.-Hil. in the area of genetic resources of the Universidade Federal de Goiás - Regional Jataí. The results were submitted to descriptive analysis and multivariate analysis, estimating the mean Euclidean distance obtained from the fruiting attributes analyzed. The measure of similarity and custering of the provenances was done by the optimization algorithm of Tocher and dendrograma UPGMA. There was a coincidence of clusters, which confirms the distribution of genetic diversity of the genotypes in the germplasm bank of Anacardium humileA. St.-Hil. evaluated. The results obtained can be used for the selection of individuals of the species in future works of breeding and conservation of the specie.
Esclarecimento e indústria cultural: algumas reflexões acerca da neurocultura
Authors: Pereira Mateus Abreu , Souza Mauricio Rodrigues de
Published: November 2019

Resumo As inovações da neurociência e suas repercussões fizeram do cérebro não apenas um órgão, mas um ator social relevante na contemporaneidade. Tal conjuntura propiciou o advento da neuroascese - isto é, práticas e discursos de ação direta sobre o cérebro no intuito de potencializar seu desempenho -, o que, por sua vez, resultou em uma cultura cerebral (neurocultura). Diante de tal quadro, este estudo adotou como objetivo principal analisar alguns elementos dessa neurocultura por intermédio de referências conceituais advindas da Teoria Crítica da Sociedade, particularmente as noções de Esclarecimento (Aufklärung) e indústria cultural. Em termos conclusivos, identifica na propaganda da neuroascese um esquema de dominação e uniformidade que acaba por reificar as massas segundo critérios que reduzem o sujeito à mera expressão da sua atividade cerebral.

Published: November 2019

ABSTRACT: Olive is one of the strategic products of Guilan province, northern Iran. Hence, it is very important to determine the optimal production pattern of olive, given the resources scarcity and the assessment of physical and Comparative Advantage (CA). In this study, three physical advantage indices for olive production in Guilan province during 2008-2016 were investigated. Also, the CA, protection and competitiveness indicators of olive production at Guilan province for 2016-17 cultivation years were calculated using the Policy Analysis Matrix (PAM). Results showed that Guilan province had scale advantage in olive production. The highest degree of olive plantation concentration was on 2008 with scale advantage index of 2.49. Also, results of efficiency advantage showed that, except for 2008, olive production had efficiency advantage over all under study years at Guilan province. Results of Domestic Resource Costs (DRC) and Social Cost Benefit ratio (SCB) indicators for both traditional and commercial olive plantations revealed the CA of olive production in Guilan province. Also, the competitiveness indices values (UCd and UCx) for both traditional and commercial olive plantations were less than 1. So, the olive production systems in Guilan province had the ability to compete with domestic and international competitors.
Análise do desempenho de adensamento da massa refratária de sílica usada em fornos de indução

Published: November 2019

Resumo As indústrias de fundição de ferro fundido usam em seu processo grande quantidade de sucata zincada, o que tem contribuído para a redução da campanha do revestimento refratário de fornos de indução a cadinho já que o vapor de zinco formado no aquecimento migra para o centro do refratário, condensando em regiões externas do forno, próximo à bobina refrigerada, gerando curto circuito entre as espiras. O revestimento refratário usado é uma massa seca à base de sílica conformada por vibração. Foram comparadas quatro massas de sílica, com base na morfologia e distribuição granulométrica, para explicar o comportamento de adensamento. Foram avaliadas também a porosidade aberta, absorção de água e retração linear das massas sinterizadas. A massa que apresentou maior densidade vibrada e sinterizada foi indicada para minimizar penetração de vapores e escórias. A única restrição seria a maior influência do processo de compactação sobre o adensamento deste material.

Abstract The aim of this work was to study the effect of the microwave radiation on the thermal and spectroscopic features, as well as about arrangement (order-disorder) and morphological properties, of the layered manganese oxide with birnessite-type structure. The route employed to obtain Na-birnessite matrix was redox precipitation. The products were characterized by X-ray diffraction, thermal analysis (TG-DTG-DSC), infrared (FTIR) and Raman spectroscopy, scanning electron microscopy (SEM) and nitrogen adsorption-desorption technique. The results showed that microwave radiation influenced in a short time (5 min) the octahedral ordering of birnessite, as well as in increasing the crystallite size. Thermal analysis showed that the thermal behavior of the lamellar matrix was different from that of birnessite under microwave radiation. After microwave-assisted hydrothermal treatment, FTIR and Raman spectroscopy investigations were used to differentiate ordered and disordered birnessites. Otherwise, there were no changes in SEM morphology of the lamellar-type phases, but the particle size changed.

Abstract Biomaterials, such as tricalcium phosphate, can have different resorption rates in the organism that depend on their physicochemical properties, where the surface condition, such as morphology, size of particles and porosity, is important. In this work, we studied the coating of natural Luffa cylindrica matrix with β-tricalcium phosphate, using the dip replica forming method, in order to adjust the surface conditions to meet the demand of bone resorption. The materials were characterized in terms of specific surface area, particle shape, imaging in electronic scanning microscope, and zeta potential in water media. The suspensions used for coating of the matrices were produced with distilled water and sodium silicate as dispersant and carboxymethyl cellulose as a binder element. Rheological measurements were performed on rotational rheometer and viscometer. The products generated with 2.5 wt% of sodium silicate and 0.75 wt% of carboxymethyl cellulose, after sintering, had pore sizes consistent with high rates of reabsorption and porosity that suggest a future use as a biomaterial.

Published: November 2019

Abstract This work aimed to produce zeolite membranes MCM-22 using two methods of synthesis, dip coating (DC) and vapor phase transport (VPT), to be evaluated in the oil/water emulsion separation process. The membranes were prepared at 150 °C for 10 days and characterized by X-ray diffraction and scanning electron microscopy. They were evaluated in tests of pure water permeation and oil/water emulsion separation system of a synthetic effluent, using a stainless-steel module under the conditions of the initial concentration of the emulsion of 100 mg/L, temperature of 25 °C and pressure of 2.0 bar. The results showed that the MCM-22 zeolite membrane by DC had the final value of the permeate concentration of 3.2 mg/L and the membrane prepared by VPT presented a final value of 3.9 mg/L which were within the standards required by Resolution No. 392 of CONAMA which is up to 20 mg/L of mineral oils.
