Projeto, construção e análise de um prototipo vibracional em escala de bancada aplicável ao tratamento de água de produção de petróleo bruto, mediante inovadora operação híbrida de adsorção e auto-flotação

A self-flotator vibrational prototype electromechanical drive for treatment of oil and water emulsion or like emulsion is presented and evaluated. Oil production and refining to obtain derivatives is carried out under arrangements technically referred to as on-shore and off-shore, ie, on the continent and in the sea. In Brazil 80 % of the petroleum production is taken at sea and area of deployment and it cost scale are worrisome. It is associated, oily water production on a large scale, carrier 95% of the potential pollutant of activity whose final destination is the environment medium, terrestrial or maritime. Although diversified set of techniques and water treatment systems are in use or research, we propose an innovative system that operates in a sustainable way without chemical additives, for the good of the ecosystem. Labyrinth adsor-bent is used in metal spirals, and laboratory scale flow. Equipment and process patents are claimed. Treatments were performed at different flow rates and bands often monitored with control systems, some built, other bought for this purpose. Measurements of the levels of oil and grease (OGC) of efluents treaty remained within the range of legal framework under test conditions. Adsorbents were weighed before and after treatment for obtaining oil impregna-tion, the performance goal of vibratory action and treatment as a whole. Treatment technolo-gies in course are referenced, to compare performance, qualitatively and quantitatively. The vibration energy consumption is faced with and without conventional flotation and self-flotation. There are good prospects for the proposed, especially in reducing the residence time, by capillary action system. The impregnation dimensionless parameter was created and confronted with consecrated dimensionless parameters, on the vibrational version, such as Weber number and Froude number in quadratic form, referred to as vibrational criticality. Re-sults suggest limits to the vibration intensity

Efeito da salinidade, densidade de estocagem e da infecção hipodermal e necrose hematopoiética (IHHN) na imunidade do camarão Litopenaeus vannamei cultivados em fazendas do Rio Grande do Norte

The main problem faced by the shrimp industry are the infectious diseases. The hypodermal and hematopoietic necrosis infection (IHHN) is one of the major cause of disease in the cultured shrimp, Litopenaeus vannamei. Environmental changes involving water quality, oxygen concentration, salinity, temperature, stocking density, presence of pathogens, among others, triggering a stressing condition for the cultured shrimp, weakening them and allowing the outbreak of diseases. The stress on the animal leads to a change in the molecules immune response components, which can be used as indicators of shrimp health. Thus, the objective of the present study was to evaluate the effect of salinity, stocking density and IHHNV infection on the L. vannamei shrimp. The immune parameters used to check the shrimp health were the total hemocytes counts (THC), the agglutinating activity (AA) and the clotting time (CT) of the serum of shrimp. These parameters were analyzed in healthy and IHHNV-infected shrimp, grown in low (0-0.5 ), medium (19-24 ) and high (> 38 ) salinity, and extensive (7-12 cam.m-2), semi-intensive (15-25 cam.m-2) and intensive (33-45 cam.m -2) stocking density. The IHHNV infection rate was significantly higher in low salinity (P<0.005) and intensive density (P<0.005), both stressful conditions for L. vannamei. Low salinity significantly increased THC (P<0.05) and decreased and CT (P<0.05) in healthy and infected shrimp, but AA (P<0.05) significantly decreased in healthy shrimp at medium salinity. Culture intensification did not affect the THC, AA and CT of healthy and infected shrimp (P>0.05). The IHHNV infection did not affect any immune parameters of shrimp cultured at different salinities and stocking densities. It is necessary to emphasize that this study was conducted in shrimp grown in ponds, where several environmental factors are acting simultaneously. Thus, further studies are needed about the influence of other environmental factors on the immune parameters of shrimp cultured in pond

Geospatial estimation-based auto drift correction in wireless sensor networks

Wireless sensor networks are often deployed in large numbers, over a large geographical region, in order to monitor the phenomena of interest. Sensors used in the sensor networks often suffer from random or systematic errors such as drift and bias. Even if they are calibrated at the time of deployment, they tend to drift as time progresses. Consequently, the progressive manual calibration of such a large-scale sensor network becomes impossible in practice. In this article, we address this challenge by proposing a collaborative framework to automatically detect and correct the drift in order to keep the data collected from these networks reliable. We propose a novel scheme that uses geospatial estimation-based interpolation techniques on measurements from neighboring sensors to collaboratively predict the value of phenomenon being observed. The predicted values are then used iteratively to correct the sensor drift by means of a Kalman filter. Our scheme can be implemented in a centralized as well as distributed manner to detect and correct the drift generated in the sensors. For centralized implementation of our scheme, we compare several krigingand nonkriging-based geospatial estimation techniques in combination with the Kalman filter, and show the superiority of the kriging-based methods in detecting and correcting the drift. To demonstrate the applicability of our distributed approach on a real world application scenario, we implement our algorithm on a network consisting of Wireless Sensor Network (WSN) hardware. We further evaluate single as well as multiple drifting sensor scenarios to show the effectiveness of our algorithm for detecting and correcting drift. Further, we address the issue of high power usage for data transmission among neighboring nodes leading to low network lifetime for the distributed approach by proposing two power saving schemes. Moreover, we compare our algorithm with a blind calibration scheme in the literature and demonstrate its superiority in detecting both linear and nonlinear drifts.

Different complexation behavior of P-functionalized ferrocene derivatives towards SnCl2 , SnCl4 and SnPh2 Cl2 : auto-ionization and redox-type reactions

The novel phosphonyl-substituted ferrocene derivatives [Fe(η(5) -Cp)(η(5) -C5 H3 {P(O)(O-iPr)2 }2 -1,2)] (Fc(1,2) ) and [Fe{η(5) -C5 H4 P(O)(O-iPr)2 }2 ] (Fc(1,1') ) react with SnCl2 , SnCl4 , and SnPh2 Cl2 , giving the corresponding complexes [(Fc(1,2) )2 SnCl][SnCl3 ] (1), [{(Fc(1,1') )SnCl2 }n ] (2), [(Fc(1,1') )SnCl4 ] (3), [{(Fc(1,1') )SnPh2 Cl2 }n ] (4), and [(Fc(1,2) )SnCl4 ] (5), respectively. The compounds are characterized by elemental analyses, (1) H, (13) C, (31) P, (119) Sn NMR and IR spectroscopy, (31) P and (119) Sn CP-MAS NMR spectroscopy, cyclovoltammetry, electrospray ionization mass spectrometry, and single-crystal as well as powder X-ray diffraction analyses. The experimental work is accompanied by DFT calculations, which help to shed light on the origin for the different reaction behavior of Fc(1,1') and Fc(1,2) towards tin(II) chloride.

Cooperação desportiva e auto-conceito de competência : Um estudo em equipas de futebol

A cooperação apresenta-se como a base de qualquer organização, mas também das equipas desportivas. O comportamento cooperativo é influenciado pela estima e confiança que o indivíduo tem em si. A confiança entre os indivíduos resulta da mediação entre o comportamento de interesse próprio e o interesse pelo outro, promovendo desta forma a cooperação entre os membros. Vários autores referem as noções de competência relacionadas com comportamentos de confiança. Desta forma estudaram-se no presente estudo as correlações entre a cooperação desportiva e o auto-conceito de competência. A amostra foi constituída por 120 atletas do sexo masculino de equipas profissionais e semi-profissionais de futebol. Os instrumentos utilizados "Questionário de Cooperação Desportiva" e "Questionário de Auto-Conceito de Competência", revelaram possuir qualidades psicométicas aceitáveis. A análise dos resultados revelou correlações estatisticamente significativas entre a dimensão de cooperação situacional e as dimensões, cognitiva, social e criativa do auto-conceito de competência, assim como a dimensão de cooperação incondicionada com as dimensões cognitiva e social do auto-conceito de competência. /ABSTRACT: The cooperation comes as the foundation of any organization but also of sports teams. The cooperative behavior is influenced by the esteem and confidence that the individual has in himself. Trust between individuals result of mediation between the behavior of self-interest and concern for others, thereby promoting cooperation among members. Several authors refer to the notions of competence-related behaviors of confidence. Thus it was studied in the present study the correlations between the sporting cooperation and self-concept of competence. The sample was composed of 120 male athletes of professional teams and semi-professional football. The instruments used "Cooperation Sports Questionnaire" and "Self-Concept Questionnaire for Competence," have revealed qualities psicométicas acceptable. The results showed statistically significant correlations between the dimension of cooperation and situational dimensions, cognitive, social and creative self-concept of ability, as well as the size of unconditional cooperation with the cognitive and social dimensions of self-concept of competence.

Contributos das percepções de auto-eficácia e de instrumentalidade para a promoção da aprendizagem auto-regulada no ensino profissional

Assumindo a teoria sociocognitiva de Bandura como marco teórico, o presente estudo aborda as percepções de auto-eficácia e de instrumentalidade enquanto preditoras da auto-regulação da aprendizagem e as influências que as variáveis sexo, idade, habilitações escolares e profissão do pai e da mãe, ano de escolaridade, curso profissional, quantidade de módulos em atraso e quantidade de horas de estudo semanais poderão ter. A amostra é constituída por 521 formandos de ambos os sexos de uma escola profissional privada. Os instrumentos utilizados foram a Ficha de Dados Pessoais e Escolares, o Questionário de Auto-Eficácia da Auto-Regulação da Aprendizagem e o Questionário de lnstrumentalidade da Auto-Regulação da Aprendizagem. Os resultados corroboram a literatura ao verificar-se que as raparigas são mais auto-reguladas na sua aprendizagem, estudam mais tempo e têm menos módulos em atraso do que os rapazes. Verificou-se também a influência do curso profissional sobre as percepções de auto-eficácia e instrumentalidade percebidas. /ABSTRACT: Assuming Bandura’s social-cognitive theory as our framework, the present study refers to the perspectives of self-efficacy and instrumentality as predictors of self­regulated learning and the influence that the variables sex, age, parents school degree and profession, grade and vocational course, the number of modules in which the students weren't successful at and the amount of study hours per week might have on them. The sample is formed by 521 students of both genders from a private vocational school. The instruments used were the FDPE (Sociodemographic data file), QSEsrl (Questionnaire of Self-Efficacy of Self-Regulated Learning) and and Qlsrl (Questionnaire of lnstrumentality of Self-Regulated Learning). The results corroborate previous studies and reveal that female students have higher perceptions of self-efficacy and instrumentality, possess fewer non-successful modules and study more time than the male students. There are significant differences throughout the vocational courses for the perceived self-efficacy and instrumentality.

Monomanias - auto-narrativas e auto-ficções: estudo sobre as manias do eu como sintoma civilizacional e seu reflexo nas artes plásticas : Monomanias - auto narratives and auto-fictions: study on the manias of the self as a civilizational symptom and their reflection in contemporay art

A palavra monomania provém do grego monos que se traduz por "um" e mania que significa "mania". O emprego do termo em psiquiatria deve-se a Esquirol e mais tarde a Pierre Janet. Contudo, o uso da palavra não se circunscreve ao campo da psiquiatria, o conceito de monomania é também usado para definir as denominadas "manias do eu". Nos dias de hoje, a subjectividade, a particularidade de cada indivíduo apartou-se da noção de Homem como um todo objectivo. A massificação gerou a sociedade do narcisismo. A World Wide Web permitiu ao sujeito dar a conhecer ao mundo a sua individualidade. O sujeito é livre de se mostrar, de se fazer ouvir, de contar as suas histórias e principalmente a sua própria. À semelhança do nosso quotidiano, podemos encontrar na arte contemporânea propostas artísticas que se prendem com o conceito de monomania, como o exemplo das mitologias individuais, auto-narrativas e auto-ficções de Sophie Calle: "de vivre sa vie pour faire ceuvre et de faire ceuvre pour vivre sa vie." ABSTRACT: Etymologically, "monomania" originates from the Greek words "monos" and "mania". The former refers to the notion of "one" and the latter to "mania". The term's introduction in the field of psychiatry is attributed first to Esquirol and later Pierre Janet. Usage of the word isn’t, however, exclusive to psychiatric jargon: the concept of monomania is also used to define so called "manias of the self’. Today, the subjectivity and specificity of each individual have distanced themselves from the notion of Man as an objective whole. Massification has led to a society of narcissism. The World Wide Web has allowed the subject to make her individuality known to the world at large. The subject is free to exhibit herself, make herself heard, tell her stories, and especially her own. ln a way similar to daily life, we find agendas in contemporary art that approach the concept of monomania, such as the personal mythologies, self-narratives and selffictions of Sophie Calle: "de vivre sa vie pour faire oeuvre et de faire oeuvre pour vivre sa vie."

Auto do Velho da Horta: uma farsa para rir?

Em 1512 Gil Vicente levou ao palco o seu Auto do Velho da Horta, anunciado como farsa na didascália inicial. O género e também o enredo aí resumido (os amores de um velho por uma moça, os enganos da alcoviteira) prefiguram uma peça cómica e prometem risos. Revemos neste artigo alguns aspetos do cómico na peça, à luz da bibliografia e das diferentes leituras de que foi objeto. Julgamos que persistem interrogações pertinentes sobre a prevalência, ou não, da dimensão lúdica da peça, veículo facilitador da ação moralizadora que se pretendia exercer no espaço da corte, e sobre uma matriz mais universalista que lhe está subjacente na abordagem de tópicos literários como o do mundo às avessas ou o da loucura amorosa.

The Rational for Auto Vaccines in Poultry Colibacillosis

Colibacillosis is a rather important economic problem for poultry production, associated to Avian Pathogenic Escherichia coli (APEC) strains, which may cause several extraintestinal pathologies, such as airsacculitis and cellulitis in broiler chickens, and salpingitis and peritonitis in broiler breeders, leading to septicemic mortality. Control of morbidity and mortality in the outbrakes of colibacillosis may be performed with antibiotics and/or by vaccination. The use antibiotics is frequently inef - fective as Escherichia coli ( E. coli ) is considered the largest reservoir of antimicrobial resistance, characteristic that may even transmit to other bacteria, turning the situation into a serious problem of public health. Vaccination may be the alternative solution but as many different strains arise, flock-specific autovaccines seem to be needed under several possible protocols, with live attenuated and/or inactivated vaccines from different strains that should be identified and characterized according to their virulence factors, within different flocks.

A auto-interpretação de Husserl em 1930-31: o Nachwort às Ideen como escrito polémico

This essay seeks to expose Husserl’s defensive attitude towards what he calls “the mistaken views” found in the new ways of conducting phenomenology, in the Epilogue to his Ideas. While the polemic side of Husserl’s project, basically but tacitly against Heidegger, is underlined, it is also sustained that this auto-interpretive piece is a fundamental key within Husserl’s corpus in that it defines the direction of the phenomenological project. At the centre of the controversy are the answer to the objections of intellectualism and solipsism, and the disavowal of all forms of anthropologism in the conception of subjectivity.
