Tornando Porto Alegre destino: rastros das iniciativas de ativação turística a partir da literatura para visitantes
Authors: Ragagnin Pimentel Maurício , Castrogiovanni Antonio Carlos
Published: September 2019

Parte-se da noção de que o turismo é uma invenção do século XVIII que tem se transformado e ampliado sua presença no mundo, articulando novos locais em um sistema global de destinos. Assim, este texto busca examinar como Porto Alegre, capital do Rio Grande Sul, passa a fazer parte de tal sistema. Como a cidade se torna objeto do 'olhar do turista' (URRY, 2001)? Quais foram as iniciativas dos porto-alegrenses para habilitar seu território a esse tipo de intencionalidade? Para isso utilizou-se como principal fonte de investigação um corpus de 135 documentos da literatura produzida para visitantes, tais como guias de viagem, folhetos, catálogos, matérias de suplementos de turismo em jornais e revistas especializadas e blogs de viagem. Propõe-se uma periodização e caracterização de cinco momentos, ou arranjos, do turismo neste destino ao longo do tempo. Considera-se ainda que o conteúdo designado pelo referente 'Porto Alegre' alterou-se de acordo com a evolução urbana da cidade, assim como o modo em que a função turismo ali se articula e interage com outros impulsos urbanizadores, em um processo com desdobramentos futuros.
Parque Pelotense: um espaço de lazer em Pelotas/RS
Authors: Hallal Dalila Rosa , Müller Dalila
Published: September 2019

Neste artigo analisamos o surgimento e a trajetória do Parque Pelotense e sua importância para o lazer em Pelotas, no período de 1883, quando é inaugurado, até 1916, quando é arrendado, não sendo mais dirigido pela família Souza Soares. Inicialmente discutimos a questão dos parques no mundo e no Brasil. Posteriormente fazemos um “passeio” pela história do Parque Pelotense, também chamado de Parque Souza Soares, e seus usos principalmente enquanto espaço de lazer. As fontes desta pesquisa foram bibliográficas e documentais, existentes no acervo da Biblioteca Pública Pelotense; no Instituto Histórico e Geográfico do R. G. do Sul; no acervo fotográfico Nélson Nobre Magalhães – Memórias de Pelotas, principalmente Almanaques e jornais diários de Pelotas. Pode-se identificar que o Parque foi um dos principais espaços para o lazer dos pelotenses, um espaço capaz de estabelecer relações sociais mediante práticas esportivas, educativas, culturais, artísticas e ambientais. O Parque Pelotense era um local de lazer completo para a época, com muita cultura, beleza e diversão, vinham visitantes de vários lugares para conhecer e apreciar o Parque. Com o passar dos anos, o Parque foi abandonado e posteriormente loteado. Hoje não resta mais nada, atualmente existe no local uma escola, posto de saúde, casas residenciais, comércio e outros.
Pricing in the pig production
Authors: Bartha Andrea
Published: September 2019

During my research work I will exame the state of pig production and the pigmeat trade in Hungary as well as in the EU. In this article I am looking at this branch, I plan to ask consumers about this topic. There is no point in importing pork if there is no market for it. The reality is that we like what is new, unusual and different. What lies behind this way of thinking?Everybody agrees, consumer habits differ culturally, and this is true in European countries as well. I find it interesting to examine what parts of the pig are favoured the most by consumers in certain countries. As habits are different we can say that certain countries prefer pork chops while on other countries’ menus pork knuckles can be found. If we follow this train of thought it becomes apparent that due to these differences the price of pork varies from country to country.According to figures, it is clear that certain countries are able to produce pork products cheaper. Since market works on the principle of supply and demand, those who offer their products cheaper will have a greater chance of remaining in this sector. Those on the other hand who can only produce their products at a higher price will eventually disappear from the market. The price is determined by the rate of the forint to the euro. Today’s strong forint is leading to the growth in imports. Recently, pork exports have fallen, but if the rate were to be 280 forints as it has been in the past, then it would be more favourable to sell pork products.As Hungarian prices are high, meat processing companies are forced to import from neighbouring countries, which means a cheaper source of product. This has led to a decrease in the number of pig in Hungary meaning that we are now an overall importer of pork products rather than an exporter.
Prospects of tobacco sector due to changing of union subsidy system
Authors: Bittner Beáta
Published: September 2019

Some 80% of the revenues from tobacco production originate from subsidies, therefore the existence of the tobacco industry basically depends on the system of subsidies. According to the current position, in the transitional period of introduction of the CAP reform (from 2006 to 2009) at least 40% of tobacco premiums shall be decoupled from the production, while the tobacco producing member states may decide to continue to pay the remaining 60% (or a less rate, depending on the rate of decoupling) in a coupled form. Tobacco premiums shall be fully decoupled as from the 2010 crop, however farmers will be eligible only for 50% of the subsidies, and the rest 50% shall be used for subsidising rural developments in tobacco producing regions (Radóczné, 2007).This change affects the section very seriously. In EU-15 member states this system was introduced in 2006, which resulted in giving up tobacco growing by high percentage of the farmers (70-80% reduction of tobacco production in Greece and Belgium, and 45% reduction in Portugal). In Hungary – due to the small scale of the tobacco section – this rate reduction in production would jeopardise the existence of the section, therefore we are interested in maintaining the existing system of coupled subsidies to as a large extent and for as long time as possible.This study shows the possibility of tobacco sector before and after introducing the changes in the system of subsidies, and formulates the most serious problems and roles of the sector.
Analysis of organic farming’s economic viability at different subsidy levels
Authors: Kormosné Koch Krisztina
Published: September 2019

Applying a data-collection-based economic model, I analyzed the economic viability of organic farming at different subsidy levels. The database is concentrated on the Hortobagy region. On the basis of data, I built an average sized and operated organic farm model with both arable land cultivation and animal keeping activities. The analysis of viability is based on gross profit calculation and compared with the criteria of the long-term economic viability, determined by the author. This study summarizes the most important results of the analysis.
The study of environment-conscious attitudes in the food-industry companies of the Northern-Plain Region
Authors: Odor Kinga
Published: September 2019

that the world of business, profit and work is not a hermetically closed area, but is in interaction with its closer and wider surroundings, ultimately with society and the natural environment.The affectedness of each sector and company varies. To be able to tackle these problems, first and foremost the commitment of companies towards environmentally conscious attitude is necessary, which can form as a result of inner obligation or outer pressure. Thus companies will be concerned to measure and quantify the environmental effects of all activities.Some of the companies have already given their votes for environment-protection. Both internationally and at home it seems that the responsible leaders of more and more companies build social, human rights and environmental protection considerations in the objects and values of the company apart from profit maximization.In my thesis I present the data gathered from a questionnaire survey carried out with food-industry companies in the Northern-Plain Region. The aim of the survey was to evaluate the commitment of companies towards environmental protection via solid data. The fact that more than half of the respondents found the positive effects of environmental protection of little importance and that environmental protection was the last among the aims of some companies reflected greatly in the following outcomes.
Economics of broiler fattening in Hungary
Authors: Szőllősi László
Published: September 2019

The purpose of this study is to present economic circumstances of Hungarian broiler sector based on secondary data after brief introduction of international and home situations. Then it analyzes costs, revenues and profit relationships of producers, which has competitive efficiency indicators and high standard production based on a model created on the basis of primary data.The paper confirms the Hungarian poultry sector international competitiveness falling. One important reason of this situation is the low profitability in the sector, which is typical of both farms produce under worse efficiency indicators and high standard producers. Beside lack of technological standards and efficiency, adverse trend of output and input price – mainly feed price – impact low profitability.Realization of technological developments and improvements according to international tendency, which affect directly or indirectly the efficiency and costs of broiler fattening are determining in point of realizable profit
Experiment of quality properties of dehydrated fruits
Authors: Antal Tamás
Published: September 2019

The lyophilization is the joint application of freezing and drying. It is an up-to-date conserving procedure, the point of which is that the humidity existing in the frozen humid material is transferred from the solid state directly into the gaseous state at a temperature below 0 oC under vacuum. Out of the procedures applied nowadays, this is the most tolerant drying process.With regard to the high investment and operational costs, freeze drying is applied only for valuable, heat-sensitive materials when the technological aim is to preserve such properties as aroma, taste and colour as well as such components as proteins and vitamins. This procedure is suitable for drying and conserving certain foodstuffs, stimulants, organic chemicals, medicines and similar sensitive and valuable materials.In our institute, we have been conducting freeze drying experiments with regional fruits and vegetables since the year 2005. During the first phase, we examined the heat- and material transfer as well as the abstraction of humidity, while during the second phase we analysed the rehydration ability and nutrient content of the freeze-dried materials as compared to those dried with the method of convection. Moreover we have conducted penetration measurements with a portable hardness tester.To sum up the results gained so far, we can state that the quality of the lyophilized materials is better than those dried in the traditional way. It originates partly in the fact that the temperature and pressure applied for the freeze drying are smaller and the drying period is far longer than for the convection drying.In contrast to convection-dried materials, freeze dried materials set in close to their original water-content, keep their original shape and size after being rehydrated. The reason of it the porous, spongy structure (flexible cell wall) of the lyophilized products which is able to take up moisture quickly. In addition, the lyophilized products can be rehydrated faster than those dried in the traditional way.Regarding the results of the chemical analyses, the following conclusion can be drawn: the vacuum freeze drying results a small decrease of nutrient content and nutritive value for the lyophilized products.The results of the hardness tests support the statement that the majority of agricultural materials cannot be considered as an ideal flexible body, because during the experiment the flexibility coefficient changed when going from the surface of the material inwards. In addition, the penetration tests also confirm that the surface of the convection-dried vegetables is at least 1.5-3 times harder than that of the freeze-dried products. The reason of it that it takes place during the drying denaturation processes.The article summarizes the results of our research work listed above, in accordance with our experiments conducted by using the characteristic fruits (apple, plum) of the Nyírség Region.
The effect of nickel-contamination, nitrogen-supply and liming on the chemical composition of perennial ryegrass (Lolium perenne L.)
Authors: Sipos Marianna
Published: September 2019

Plant-production is determined by many production-factors. Each of these factors became subject of research-works through the years, still we state, that studying their interaction is even more important. For studying these interactions we set up a potexperiment, within that the direct effect and the interactions of four factors was inspected: soil, nitrogen-supply, nickel-loading and liming. Experiments were carried out on two soil types with extremely different characters: one was a chernozem soil with good fertility and buffering capacity, the other was a shifting sand soil with low humus-content and buffering capacity. Nitrogensupply and liming was added on two levels, while nickel on three within 12 combinations on each soil types. Plant production was cut two times within the vegetation period. The amount of production and dry matter was weighted, fractured and their element-content was measured by an ICP-detector.Ca-content on the shifting sand soil was determined by all three factors, however the interaction between nickel-loading and liming was also significant. Nitrogen and liming increased Cauptake, that is due to appropriate nutrient-supply and improvement of a better pH-value. On the chernozem soil nitrogen and CaCO3 also increased the Ca-content. This is caused by a better nutrient supply and a higher amount of available Ca-ions.On the shifting sand soil nickel content was increasing parallel to higher nitrogen-dosages. In presence of higher nickelamount the nickel-content of plants was also increasing, still according to liming, this increment was different. On the chernozem soil nitrogen a nickel increased Ni-uptake. However, liming also had a positive effect on Ni-content, that can be explained by the high amount on colloids in the soil, the adsorption of Ni-ions on them and in presence of liming material the replacement of Ca-and Ni-ions. The potassium-content on the shifting sand soil was different in each liming-combination. In combinations without nickel the potassium-content of limed and not limed combinations was on the same level. In not limed combinations by adding nickel potassiumcontent was increasing, while in limed combinations no change was observed. On the chernozem soil by adding liming material the amount of uptaken potassium was decreasing, that is due to the antagonism between Ca- and K-ions.
Agree or Disagree? On the Role of Negotiations for the Valuation of Business Enterprises
Authors: Follert Florian , Herbener Jeffrey , Olbrich Michael , Rapp David
Published: September 2019

In the division of labor, economizing valuations require an appraisement of the structure of market prices of goods beforehand. Yet, investment decisions concerning the purchase of an entire business enterprise, for example, necessitate considerations beyond appraisement. An economizing valuation of businesses must be based upon both appraisement and a genuine investment appraisal which provides the valuing person with the marginal price he can barely accept. However, even though the computation of this marginal price is a necessary step towards an economizing investment decision, it is still not sufficient. In case of a company purchase, the price to be paid is unknown beforehand. Therefore, an economizing valuation of firms not only requires both appraisement and investment appraisal but also a negotiation of the final price to be paid. Because the corresponding negotiation process must be characterized as a terra incognita in Austrian economics, this paper investigates in depth the negotiation between the involved parties as the final step towards their economizing valuations and discusses purposive negotiation tactics.
Diseño de secadoras continuas de trigo
Authors:   , Giner Sergio Adrián
Published: September 2019

El diseño de secadoras de granos es un problema complejo que ha sido abordado empíricamente o mediante tratamientos teóricos muy simplificados. Actualmente, el estudio del comportamiento de secadoras requiere conocer distintos temas, y debe decirse que si bien se ha avanzado en muchos de los aspectos teóricos de la transferencia de calor y materia aire-grano y las relaciones entre calidad de grano y tratamientos térmicos, los datos de diseño de secadoras son fragmentarios. Resulta necesario integrarlos para pronosticar el comportamiento de un equipo. El programa de simulación a desarrollarse aquí tratará de contribuir en este aspecto. El resultado principal de dicho programa será el cálculo del tiempo de residencia, período requerido para reducir la humedad de los granos desde el valor de entrada al valor deseado a la salida de la secadora. Otros propósitos importantes son la selección de condiciones operativas tales que el período de permanencia de los granos en la secadora no dañe su calidad, y no implique un alto consumo de energía.

El Principio de Equivalencia, su verificación experimental y su relación con las fuerzas fundamentales
Authors:   , Riveros Ricardo Carlos
Published: September 2019

La exploración experimental del Principio de Equivalencia y de la "correcta" teoría de la gravitación tiene importantes consecuencias para la física actual. Esta exploración se basa en la proposición de nuevos y mas precisos experimentos, en el análisis y reanálisis de experimentos ya realizados desde nuevos puntos de vista y en la formulación de modelos teóricos adecuados tanto como hipótesis de trabajo para la comprensión del fenómeno gravitatorio en sí o como base para proponer experimentos e interpretar su resultado. En este trabajo, se intenta cubrir algunos de estos aspectos, ya que: a) Se reanaliza un experimento realizado para comprobar la hipótesis de existencia de modificaciones a la gravitación Newtoniana dependientes de la composición (violaciones al PE); b) Se propone un nuevo experimento en relación con éste último que se espera no contenga ciertos problemas sistemáticos hallados en aquél; c) Se propone un modelo para el análisis de todos los experimentos de física de altas energías en relación con el PE; d) Se reanalizan los clásicos experimentos de deflexión solar de la luz desde dos ópticas diferentes, buscando por un lado acotar posibles desviaciones de la gravitación Newtoniana como límite correcto de la gravitación a bajas intensidades de campo y bajas velocidades, y por otro buscando acotar la existencia de un nuevo tipo de partículas en el Sol.
Estudio de los efectos del ruido en sistemas dinámicos no lineales
Authors:   , Buceta Ruben C.
Published: September 2019

Los sistemas dinámicos que presentan inestabilidades han sido objeto de investigaciones exhaustivas en la última década. Sin embargo, a nuestro criterio, los efectos que introducen las fluctuaciones o excitaciones irregulares en tales sistemas, es un campo abierto de estudio e investigación. Es bien conocido que sistemas dinámicos no lineales con comportamiento periódico suelen funcionar en la vecindad de un punto de bifurcación, esto es una inestabilidad. Tal es la característica de sistemas que presentan bifurcaciones de Hopf, cuyos atractores o soluciones estables consisten de puntos fijos (o sumideros) y soluciones periódicas (o ciclos límites). En este trabajo de tesis se aborda el estudio de sistemas dinámicos con ruido que presentan bifurcaciones de Hopf.
Cromodinámica cuántica y colapso gravitatorio
Authors:   , Horvath Jorge Ernesto
Published: September 2019

Desde el punto de vista de la física la evolución estelar, desde su nacimiento hasta el inicio del colapso, puede verse como una sucesión de fusiones termonucleares con ciclos cada vez más cortos y que culmina en el isótopo nuclear más fuertemente ligado 56Fe (Capítulo I). Se cree sin embargo que el colapso hace que en el centro estelar se alcancen densidades bien por encima de la densidad donde los núcleos se disuelven formando materia nuclear. ¿Es posible que estas altas densidades sean también suficientes para lograr que los propios nucleones se disuelvan en sus constituyentes fundamentales (quarks y gluones)? ¿Pueden existir estados de materia hadrónica subnuclear que se manifiesten en estos procesos (¿materia extraña?)? ¿Cuál sería el efecto de un posible "tunnelling cuántico final" hacia un estado hadrónico más ligado aún que el 56Fe en el objeto estelar colapsante? ¿Cuál es la naturaleza del objeto compacto remanente que la ortodoxia actual identifica con estrellas de neutrones observadas como pulsars? Esta tesis pretende proponer en los Capítulos II, III y IV respuestas a preguntas y formular otras tantas relacionadas con la astrofísica relativista, a la cual seguramente sólo entendemos en forma aproximada y nos guarda aún una buena cantidad de sorpresas.
El grupo de Weyl y la estructura diferenciable de la órbita de similaridad de una esperanza condicional
Authors:   , Argerami Martín
Published: September 2019

A mediados de la década de 1980, se inició una fructífera colaboración entre H. Porta y L. Recht, a quienes pronto se les sumó G. Corach, en la que atacaron una aproximación a la teoría de álgebras de operadores desde el punto de vista de la geometría diferencial. Más tarde se fueron uniendo a este proyecto varios investigadores, como D. Stojanoff, E. Andruchow, A. Maestripieri, A. Varela. Se obtuvieron resultados de caracterización, en función de la estructura geométrica, de propiedades algebraicas de álgebras de von Neumann y C* (ver, por ejemplo, [ACS]), y aún se continúan hallando diversas generalizaciones y aplicaciones. De esa línea participa este trabajo.
Desarrollo de métodos inmunoquímicos para el análisis de prolaminas en alimentos y estudios de aspectos inmunológicos de la enfermedad celíaca
Authors:   , Chirdo Fernando Gabriel
Published: September 2019

En nuestro medio, la carencia de métodos adecuados para la determinación de prolaminas en alimentos constituye uno de los graves incovenientes asociados a la enfermedad celíaca. El método oficial actualmente empleado, para la determinación de gliadinas en alimentos, es la inmunoprecipitación en gel. Esta es una técnica de baja sensibilidad, característica que sumada a la escasa solubilidad de las prolaminas, impide la correcta evaluación del contenido de gliadinas en la muestra. En nuestro país no existe reglamentación oficial que exija la determinación del contenido de prolaminas en los alimentos, ni el rotulado de los mismos. Al respecto, la Organización Mundial de la Salud sugiere que un alimento exento de gluten debe contener menos de 1 mg de dichas proteínas por cada 100 g de producto seco. Por lo tanto, si bien algunos productos comerciales nacionales, llevan en su etiqueta la denominación "Sin TACC", en realidad, este hecho es sólo una declaración de buena fe del fabricante y no una certificación del contenido real de prolaminas del producto. Otro problema de relevancia lo constituye el diagnóstico de la enfermedad. El mismo requiere del estudio de biopsias duodenales, procedimiento invasivo y traumático, en especial para los niños. Debe tenerse presente que la enfermedad celíaca es de alta incidencia poblacional, con un valor estimado de 1:1000 en los casos con sintomatología. Sin embargo, la incidencia real puede alcanzar valores cercanos a 1:300 al incluir los pacientes asintomáticos. La alta proporción de estos pacientes demanda la implementación de pruebas de "screening" masivas. Para tal fin, la determinación de anticuerpos anti-gliadinas podría ser de utilidad. Sin embargo, la dificultad de estandarización de los inmunoensayos conduce a resultados discordantes respecto a las características de estos test. En relación a lo expuesto, los objetivos generales de este trabajo consisten en la optimización de inmunoensayos de alto nivel de detección y especificidad, para la determinación de prolaminas en alimentos y el desarrollo de un ensayo serológico de utilidad para la evaluación de enfermos celíacos. Para el logro de los objetivos indicados, se propone: 1. - Estudiar las propiedades fisicoquímicas de las prolaminas de trigo, cebada y centeno, en relación a su extracción, separación y análisis cuantitativo. 2. - Desarrollar métodos cromatográficos de purificación de prolaminas. 3. - Desarrollar un inmunoensayo cuantitativo con anticuerpos policlonales anti-gliadinas para la determinación de proteínas nocivas en alimentos destinados al consumo por enfermos celíacos. 4. - Producir y caracterizar anticuerpos monoclonales anti-prolaminas. 5. - Optimizar inmunoensayos cuantitativos con anticuerpos monoclonales. 6. - Aplicar las prolaminas purificadas al análisis de la reactividad de los anticuerpos séricos de enfermos celíacos. 7.- Desarrollar un inmunoensayo como prueba serológica para la evaluación de pacientes celíacos.
Láser de monóxido de carbono
Authors:   , Schinca Daniel Carlos
Published: September 2019

En el presente trabajo se intenta resumir la labor desarrollada en láseres gaseosos de moléculas diatómicas de excitación pulsada, particularmente en lo que respecta a láseres de monóxido de carbono de geometría axial. De esta manera, se realiza un detallado análisis espectroscópico tanto de la salida láser de las bandas de emisión del Sistema Angstrom como de la emisión espontánea de las mismas bajo diferentes condiciones experimentales. Es sabido que la molécula de monóxido de carbono se descompone irreversiblemente en una descarga eléctrica, lo que provoca una disminución del material activo disponible que termina inhibiendo la acción láser, además de contaminar la descarga. Nuestro propósito entonces es intentar disminuir dicho ritmo de descomposición por distintos medios como por ejemplo flujo o mezcla de gases, estudiando en este último caso el efecto que dicha mezcla tiene sobre las carácterísticas de la emisión del CO. Finalmente se realiza un análisis de la distribución de ganancia relativa en la estructura rotacional de las bandas láser observadas. Dicho análisis se lleva a cabo reproduciendo la intensidad de los espectros observados mediante la utilización de espectros simulados que dependen del parámetro de inversión de población vibracional.
Contribución al conocimiento de los dinoflagelados de la República Argentina
Authors:   , Boltovskoy Andrés
Published: September 2019

Se realiza un estudio de los dinoflagelados de aguas continentales de toda la extensión de la República, considerando su morfología, sistemática, ecología y distribución. La elección del tema responde al escaso conocimiento que se posee acerca de estos organismos, tanto en lo que respecta a su diversidad, como de su papel en las aguas continentales de nuestro país. En lo que respecta a los conocimientos sobre morfología y sistemática de los dinoflagelados, existe un cierto atraso en el mundo, en relación con los de hábitat marino. Se estudiaron alrededor de 850 muestras de casi todas las provincias de la Argentina. Las muestras corresponden a unas 180 localidades, que en muchos casos fueron relevadas en diferentes años, en distintas épocas del año, y a varias profundidades. El número de muestras analizado fue 3-4 veces mayor, puesto que en muchos casos no se han registrado dinoflagelados. Se presenta una introducción al estudio de la morfología, taxonomía y distribución de los dinoflagelados, con una puesta al día del tema en el mundo y en nuestro país, y una exhaustiva reseña sobre la metodología de recolección, fijación, cultivos temporarios, técnicas de microdisección, microscopia óptica, microscopia electrónica de barrido.

Emotional Labour of Judges

Our article concentrates on emotions as related to the functioning of man in the judicial system seen as a modern bureaucratic institution. Special attention is given to the work of judges due to their key position in this system. In legal discourse there is a dominating normative idea of a judge as a decision-making subject free of any emotional factors influencing their judgment. According to this traditional approach, a decision biased even in the slightest way by emotions could not be regarded as impartial, whereas judicial impartiality is regarded as one of the core values of the justice system. Our standpoint assumes not only that judges experience emotions but also asserts that they are being manifested in varied ways. Our analysis is based on Arlie Hochschild’s conception of emotional labour. Such labour is being performed when an individual reflects on his or her feelings and makes an effort either to change or to inhibit emotions which are regarded as misfitting. The necessity of emotional work is a result of cultural feeling and expression rules. It seems prima facie that there is one clear expression rule regarding displaying emotions by the judge in the Polish legal culture: no emotions allowed. However, contrary to possible reconstructed declarations and recommendations warning judges against showing emotions, the rules of expressing them in Polish courts are not unequivocal. We claim that one can distinguish between unconditional and conditional rules of expressing emotions. The former relate to expressing emotions concerning non-professional participants, and conditional rules of expressing emotions relate to professional participants in the hearing. There are situations in which an emotional reaction is reasonable, because it represents certain values to which the justice department adheres, and those in which judges regret showing annoyance or anger. The goal of the emotional labour performed is not only a realization of the value of impartiality, but also the balance of the judges that allows them to efficiently fulfil their role.

La caries y las enfermedades periodontales son infecciones donde el bioflm es un reconocido factor de riesgo microbiano que determina el inicio y progresión de una lesión. Las bacterias que causan estas enfermedades están organizadas en estructuras denominadas bioflm, que son comunidades de complejos Microbianos compuestos por una gran variedad de microorganismos con diferentes requerimientos ecológicos y un alto potencial patogénico. El bioflm es un neologismos científco que no merece ser traducido y sobre todo mal interpretado. La placa bacteriana es en realidad un bioflm microbano.
