Texto completo da fonteENGLISH ABSTRACT: This thesis covers the development of a transformerless series dip compensator. Of all known power quality problems, voltage dips are the greatest reason for concern. Series injection dip compensators offer the advantage of only having to compensate for the decrease in supply voltage during a dip. This results in significant reduction in converter ratings and energy storage requirements. The aim of this thesis was to take up previous developments and combine them with new technologies to maximize their functionality. The new design was implemented with ultracapacitors to offer a maintenance-free device lifespan of 20 years. As they are very expensive, a new topology was introduced in this thesis to maximize their use so that they become viable for industry. Furthermore, a new method of daisy chaining switches was introduced to minimize costs involved in controlling them. A single-phase compensator, with this new topology and the new way of controlling switches, was designed and built according to specifications stated by Eskom. This ultracapacitor-based dip compensator was tested with a dip generator, developed by the University of Stellenbosch for different load currents. The experimental results confirmed simulations made with identical parameters. This thesis presents a reliable and cost effective solution for dip compensation.
AFRIKAANSE OPSOMMING: Hierdie tesis dek die ontwikkeling van ’n transformatorlose duik kompenseerder. Van al die bekende toevoerkwaliteit probleme wek duike in die spanning die meeste kommer. Serie-injeksie kompenseerders het die voordeel dat hulle net kompenseer vir die verlies in die toevoerspanning tydens die duik. Dit het ’n beduidende vermindering in die omsetterkenwaardes en energiestoorvereistes tot gevolg. Hierdie tesis mik om vorige soortgelyke ontwikkelings op te volg en te verbeter met nuwe tegnologie om die funktionliteit te maksimeer. Die ontwerp is geimplementeer met ultrakapasitore wat die onderhoudsvrye toestel ‘n leeftyd van 20 jaar toelaat. Omdat ultrakapasitore so duur is moes ‘n nuwe topologie onwikkel word om die gebruik van ultrakapasitore meer ekonomies aantreklik te maak. Daar is ook ‘n nuwe manier van skakelaar beheer ontwikkel wat toelaat dat baie skakelaars oor een optise veesel beheer kan word. ‘n Enkel fase dip kompensaeerder is toe onwikkel en gebou volgens Eskom se spesifikasies. Die ultrakapasitor gebaseerde omsetter is getoets met ‘n dip generator wat deur die Universiteit van Stellenbosch ontwikkel is. Die praktiese resultate bevestig die simulasies wat gedoen is met dieselfe parameters. Hierdie tesis lei tot ‘n betroubaare en ekonomiese oplossing vir duik kompensasie.

Texto completo da fonteEl estudio de caso se inserta en la problemática de la incidencia de las habilidades directivas en el sector público, como un factor relevante en el desempeño de unidades de trabajo en los órganos del Estado. El estudio de caso es una investigación aplicada a una oficina del Servicio Agrícola y Ganadero, en la que se produjo una situación de quiebre en las relaciones interpersonales entre el Jefe de la oficina y su equipo de trabajo durante el año 2012, la que fue superada con una intervención organizacional, de la que se obtuvo hallazgos de buenas prácticas factibles de ser consideradas en la gestión directiva a nivel de gobierno. En este estudio, se analizó por medio de entrevistas a los actores involucrados en la situación de quiebre, en las que se les pidió describir, y cuando fuese pertinente, entregar su explicación respecto tanto al episodio que desencadenó el plan de intervención como de los eventos previos, contemporáneos y posteriores a dicho episodio. Sobre la base de las respuestas de los entrevistados, se construyó un relato del proceso de superación de la situación de quiebre. El análisis del relato se vinculó con los aspectos conceptuales asociados a los hallazgos, y consecuentemente, se hicieron recomendaciones sobre la gestión directiva a nivel gubernamental. En el relato se detectó un aumento del nivel de estrés en los funcionarios de la oficina hasta llegar al punto de quiebre antes mencionado, momento en que se tomaron decisiones acertadas, para dar solución a la situación, logrando un cambio en el estilo de liderazgo, lo que no sólo permitió superar este quiebre, sino recuperar un equipo de trabajo comprometido y motivado, que a su vez se transformó en un ejemplo para otras oficinas sectoriales del SAG. El análisis conceptual de los principales hallazgos se centró en la generación de una actitud efectiva de liderazgo; mejora de la comunicación con el equipo de trabajo; desarrollo de habilidades de resolución de conflictos, uso efectivo de los resultados de encuesta de clima laboral; y el apoyo institucional. Si bien el caso estudiado es un hecho puntual, tanto las acciones realizadas como los respectivos efectos que acompañan al caso, son extrapolables a situaciones generales y replicables a otros equipos de trabajo del sector público.

Texto completo da fonteThis work consists in the development and comparative analysis of comminution routes to Compact Itabirites from Quadrilátero Ferrífero, based on a large volume sample. The developed routes were: Conventional Route, comprising four crushing stages, down to 12 mm, followed by ball milling. SAB Route comprising one crushing step, down to 200 mm, followed by SAG milling and ball milling. Secondary crushing and pebble crushing were also included as variations of SAB route. Route SSSAG, comprising one crushing step, down to 200 mm, followed by SAG milling. Secondary crushing was also included as a variation of SSSAG route. In all cases grinding product was set to 10% retained at 0,15 mm. All grinding models were fitted at JKSimMet simulator on the basis of pilot plant data. Energy consumption and equipment design were compared with Bond and Donda method results. Crushing circuit design was based on industrial tests carried out for determining efficiency as a function of closed side setting (CSS). The routes were compared in term of energy consumption (kWh/t), comminution equipment numbers and the amount passing at 0,010 mm (slimes) in the grinding circuit product. The SSSAG route indicated the lowest energy consumption, together less pieces of equipment. Similar slime values were obtained for all three routes in pilot testing.

Texto completo da fonteIn this paper, we present a social application model in an attempt to improve the teaching / learning using a system developed especially for this purpose, using the programming language C #, with possible access for computers, tablets and mobile phones with Internet access. The methodology adopted is based on the use of a system of questions and answers supplied by the students and managed by the teacher, designed to meet preliminary information through supervised entries features. These features were developed after the study of the major reasons why the current information systems present shortcomings in the transfer of information. For validation of this system, we selected a group of students and teachers, while using the system was generated sufficient data to at the end of a period of time, confront the study time information, time making questions, time answering and notes with the traditional teaching model in classroom and work at home. In addition to these data, each system user responded to a questionnaire on the use of the system and its opinion about use. Keywords: Distance education. Social function of education. E-Learning.

Texto completo da fonteEl objetivo inicial de este estudio es emplear diferentes estrategias de control posibles para un inversor conectado a la red segun el código de red español y analizar el comportamiento de la tensión de salida durante caídas de tensión simétricas y asimétricas. El desarrollo analítico de las estrategias propuestas muestra los impactos de los huecos de tensión en las corrientes, tensiones, potencias activas y reactivas. Otro objetivo de esta investigación es proponer una estrategia de protecclón basada en lnteligencia Artificial para una red del Sistema de Distribución, radial o en anillo, con elevada penetración de Generación Distribuida. La estrategia de protección se basa en tres algoritmos diferentes para desarrollar un sistema de protección más seguro, redundante, y fiable, que asegure la continuidad de suministro durante perturbaciones en redes radiales o en anillo sin comprometer la estabilidad del sistema. Para clasificar, localizar y distinguir entre faltas permanentes o transitorias, se proponen en este trabajo nuevos algoritmos de protección basados en inteligencia artificial, permitiendo la mejora de la disponibilidad de la red, al desconectar sólo la parte del sistema en falta. Esta investigación introduce la innovación del uso del rele direccional basado en un sistema de comunicación y Redes Neuronales Artificiales (ANN). El primer algoritmo, Algoritmo Central (CE), recibe los datos de todos los PDs de la red en un control central. Este algoritmo detecta la dirección de flujo de cargas y calcula la corriente de secuencia positiva de todos los PDs de la red. El entrenamiento de ANNs incluye variaciones en la corriente de cortocircuito y la dirección del flujo de potencia en cada PD. Los beneficios mas significativos de este sistema son que concentra la seguridad total del sistema en un único dispositivo, lo que puede facilitar el control de la seguridad del sistema. Sin embargo, el CE no determinara con precisión la localización exacta de la falta si hay alguna perdida de información debida a una pobre comunicación. Por lo tanto, la redundancia del sistema se puede mejorar cooperando con un segundo algoritmo, el algoritmo de Zona (ZO). El algoritmo ZO se basa en un control de zona usando la conectividad entre dispositivos de protección de una misma línea. La línea en falta en esa zona puede identificarse combinando los datos de los dos PDs de la misma línea.. La ventaja mas relevante de este algoritmo es su flexibilidad para adaptarse a cualquier modificación de la red o perturbación, incluso si sólo son temporales, a diferencia del CE, que se ha adaptado para la configuración de la red existente. El tercer algoritmo de protección, algoritmo Local (LO), ha sido propuesto sin dependencia de la comunicación entre PDs; por lo tanto, el sistema de protección puede operar correctamente en el caso de una pérdida total de comunicación. Cada PD debe poder detectar si la falta esta ubicada en la línea protegida o en otra línea, utilizando sóIo la información local del PD. Según el tipo de falta, y en base a medidas locales en cada PD, de tensiones y corrientes abc, se aplican diferentes algoritmos en función del cálculo de las componentes simétricas. La principal ventaja de este algoritmo es la actuación por separado de cada PD, evitando los problemas de comunicación. En el caso de las redes radiales, se utilizan tanto interruptores mecánicos como réles de estado sóIido (SSR) para verificar las estrategias de protección, y en el caso de las redes en anillo se utilizan interruptores mecánicos, debido a las limitaciones de tensión para su conexión. Los algoritmos de protección propuestos se comparan con protecciones convencionales (Sobrecorriente y Diferencial) para validar la contribución de los algoritmos propuestos, especialmente en redes inteligentes reconfigurables.

Texto completo da fonteThe significance of this study is primarily intended to provide better understanding of axial segregation and flow of particles along SAG mills. Additionally, the current SAG mill models developed using "short" Australian and North American style mills exposes inaccuracies when applied to predict the performance of "long" mills. Thus the results of this study are expected to be useful for improving modelling of long SAG mills. Several studies of radial and axial segregation in tumbling horizontal devices at laboratory-scale and a few on pilot-scale have been conducted in the past by various researchers. Recently, industrial-scale studies of axial segregation in kilns and dry milling, particularly in the cement industry have also been conducted. However, there seems to be no work reported and cited in the literature on axial segregation studies along SAG mills. Thus the lack of previous segregation research along SAG mills has exposed a knowledge gap in the subject.

Texto completo da fonteThe comic strip "The Whole Mafalda" (1993), a creation of the Argentinean Quino, is starred by children. Mafalda, the main one, is a little six-year-old girl whose thoughts and attitudes are far beyond her age, she is critical and concerned about the humanitys fate. The comic strip - a discursive genre which belongs to the hypergenre "comics" is a tendentiously short text usually linked to humor alwas with na unexpected ending, in which tehe character may be regular or not. Mafaldas comic strips were used in a research-action as a gender-anchor to work with reading and writing in a Supporting Room for Portuguese Learning (SAA) placed at a public school on the outskirts of Cambé-Paraná, from March to June 2016. The main objective was to elaborate an interventions proposal through comic genres, particularly using the comic strip mentioned above, for a Supporting Room for Portuguese Learning (SAA). The studies by Ramos (2007; 2009; 2011; 2014) and Vergueiro (2006) are the guiding references for this proposal on the characterization of the comic genres, alongside works about comic strips developed by Ramos (2007; 2009; 2011; 2014) and the research project "Grammar, pragmatic and strips: in search of the grammatical organization of fact and value," coordinated by Professor Dr. Maria Isabel Borges (2014-2016). Other ideas and studies related to discursive genre, texts and writing by Bakhtin (2003), Costa Val (1991), Snow (1991), Pécora (1999), Franchi (2002), Antunes (2003; 2007) and Koch and Elias (2006; 2014) also based this work. The intervention project happened throughout twenty meetings, splited into four stages. The first stage was the diagnosis, in which students produced two written and strictly verbal texts from Mafaldas strips, to identify recurring gaps: problems on senses structuring, punctuation, text organization, spelling and accentuation. The second stage was the presentation of the main genres of the hypergenre "comics" and comparison of theirs similarities and differences, in which activities from the main comic genres (graphic novel, cartoon, comics, manga, free strip and comic strip) were made and compared among them later on; the students explored the features of the comics language that would help their best understanding of the texts (graphic signs, facial expressions, image position, image planes, balloons, fixed characters, punctuation, etc.). On the third stage - Working with Mafaldas comic strips the students explored the humor and the construction of sense in Quinos comics strips through the analysis of the socio- historical context and image resources. There was also a work with intertextuality with other genres (story, fable and joke). The fourth and last stage was the Final Assessment, in which the students produced texts from the initial proposals in order to compare with the previous ones and to verify the progress.Throughout the stages, there were analysis and reflections to observe the progress and conduct retakes. The students presented progress in text organization and puctuation comprehension while spelling and accentuation still present predominantly weaknesses. It was also observed a self-esteem growth from the students and relationship improvement between teacher and students.

Texto completo da fonteThis thesis focuses on controller design and analysis for induction motor (IM) drives, flux control for electrically excited synchronous motors with damper windings (EESMs), and to enhance voltage sag ride-through ability and analysis for a wind turbine application with a full-power grid-connected active rectifier. The goal is to be able to use the existing equipment, without altering the hardware. Further, design and analysis of the stabilization of DC-link voltage oscillations for DC systems and inverter drives is studied, for example traction drives with voltage sags in focus.
The proposed IM controller is based on the field-weakening controller of Kim and Sul [31], which is further developed. Applying the proposed controller to voltage sag ride-through gives a cheap and simple ride-through system.
The EESM controller is based on setpoint adjustment for the field current controller. The analysis also concerns stability for the proposed flux controller.
The DC-link stabilization algorithm is designed following Mosskull [38], where a component is added to the current controller. The algorithm is further developed.
Analysis is the main focus, and concerns the impact of the different parameters involved. Proper parameter selection for the controller, switching frequency, and DC-link capacitor is given.
The impact of voltage sags is investigated for a power-grid-connected rectifier. Here, we analyze the impact of different types of voltage sags and phase-angle jumps. The analysis gives design rules for the DC-link capacitor and the switching frequency.
Experimental results and simulations verify the theoretical results.

Texto completo da fonteSerum amyloid A protein (SAA) is an acute phase protein that has recently gained increasing interest as a potential marker for disease and treatment monitoring. We investigated SAA and CRP levels in (a) patients with various common infectious diseases (n=98), (b) patients with pyelonephritis (n=37) versus patients with cystitis (n=32), (c) healthy individuals of varying ages (n=231), (d) very immature newborn infants with or without nosocomial infections (NIs) (n=72) and (e) patients with bacterial infections treated with cefuroxime (n=81).
SAA significantly correlated with CRP in viral as well as in bacterial infections (for the total group: r2=0.757, p<0.0001) and showed a systemic inflammatory response in 90% of the patients with cystitis as compared with 23% for CRP. Equally high efficiencies (0.96 and 0.94 for SAA and CRP, respectively) were observed in discriminating between pyelonephritis and cystitis. SAA and high sensitive (hs) CRP were lower in umbilical cords (p<0.0001) and higher in elderly adults (p<0.0001-0.03) than in the other age groups; higher in immature newborn infants than in term infants; and higher in the NI group than in the non-NI group. Interindividual variabilities of the time course of the biomarkers SAA and CRP were considerable. Because of the smoothed distribution of SAA and CRP (i.e. elevations were both essentially unchanged during the first 3 days of cefuroxime treatment), these markers were not useful when deciding parenteral-oral switch of therapy, which occurred within this time period in most cases.
SAA is a sensitive systemic marker in cystitis. SAA and hsCRP in umbilical cord blood are close to the detection limit and increase with age. They increase in relation to NI in very immature newborn infants and might therefore be used in diagnosis and monitoring. Finally, SAA and CRP in adults with bacterial infections could not predict an early parenteral-oral switch of antimicrobial therapy.

Texto completo da fonteENGLISH ABSTRACT: This thesis covers the development of a multilevel cascaded inverter for the purpose of costeffective transformerless series dip compensation. Of all known power quality problems, voltage dips are the greatest reason for concern. Dips/sags occur more frequently than outages and therefore tend to be more costly for industry as modem technical equipment becomes all the more sensitive to the quality and reliability of supply. A number of devices already exist to compensate for this problem, but the cost of most of these systems does not always justify the financial losses they compensate for. All of these systems are using transformers and/or large filter components that contribute to the size, price and losses to quite a large extent. Series injection dip compensators offer the advantage of only having to compensate for the decrease in supply voltage during a dip. This results in a significant reduction in the converter ratings and energy storage requirements compared to conventional uninterruptible power supplies or shunt injection power quality devices. Existing inverter topologies, including multilevel inverters, were therefore studied and compared as possible solutions for cost-effective transformerless series dip compensation. On the basis of these considerations the multilevel cascaded inverter seems to be the most cost-effective option. The relatively low harmonic content of its unfiltered output also eliminates the need for a large output filter. A single-phase dip compensator, with this topology, was designed and built according to specifications stated by Eskom, the main utility in South Africa. Batteries as energy storage and automotive MOSFETs as switching components, proved to be most cost-effective options for the specified power ratings. Control algorithms for dip compensation with the multilevel inverter were also developed. Some of these algorithms are based on existing techniques, but two new algorithms were also developed to implement force commutation of the thyristors and to share the power dissipation in the dip compensator. Simulations indicated that these algorithms could be suitable and sufficient for their application. This dip compensator with its control algorithms was tested with a dip generator, developed at the University of Stellenbosch, for different types of loads. The experimental results confirmed the simulations and showed a very good performance for the specified conditions. An optimised design of this dip compensator will make it a cost-effective solution for dip compensation.
AFRIKAANSE OPSOMMING: Hierdie tesis dek die ontwikkeling van 'n multivlakwisselrigter, in kaskade, met koste-effektiewe transformatorlose duik kompensasie as mikpunt. Van al die bekende toevoerkwaliteit probleme wek duike in die spanning die meeste kommer. Duike kom meer gereeld voor as kragonderbrekings en neig daarom om 'n groter onkoste te wees vir die industrie soos wat moderne tegnologiese toerusting al hoe meer sensitief raak vir die kwaliteit en betroubaarheid van die toevoer. 'n Aantal toestelle wat vir hierdie probleem kompenseer bestaan reeds, maar die koste van hierdie stelsels regverdig nie altyd die finansiële verliese wat hulle moet elimineer nie. Al hierdie stelsels gebruik transformators en/of groot filter komponente wat grootliks bydra tot die grootte, prys en verliese van hierdie stelsels. Serie-injeksie kompenseerders het die voordeel dat hulle net kompenseer vir die verlies in die toevoerspanning tydens die duik. Dit het 'n beduidende vermindering in die omsetterkenwaardes en energiestoorvereistes tot gevolg in vergelyking met ononderbroke kragbronne (UPS) of newe-injeksie toevoerkwaliteit toestelle. Daarom IS bestaande wisselrigtertopologië, insluitende multivlakwisselrigters, bestudeer en vergelyk as moontlike oplossings vir koste-effektiewe serie duik-kompensasie. Van al hierdie moontlikhede lyk die multivlakwisselrigter, in kaskade, na die mees koste-effektiewe opsie. Die relatiewe lae harmoniese inhoud van sy ongefilterde uittree elimineer die behoefte aan 'n groot uittreefilter. 'n Enkelfase duik kompenseerder, met hierdie topologie, is ontwerp en gebou volgens die spesifikasies wat vasgestel is deur Eskom, die hoof elektriese kragvoorsiener in Suid-Afrika. Dit het geblyk dat batterye, en MOSFETte uit die motorbedryf, die mees koste-effektiewe opsies bied vir onderskeidelik die energiestoor en skakelkomponente. Beheeralgoritmes VIr duik kompensasie met die multivlakwisselrigter is ook ontwikkel. Sommige van hierdie algoritmes is gebaseer op bestaande tegnieke, maar twee nuwe algoritmes is ook ontwikkel vir die kommutering van die tiristors en die deling van die drywingsverkwisting in die duik kompenseerder. Simulasies dui aan dat hierdie algoritmes geskik en voldoende kan wees vir hulle toepassing. Hierdie duik kompenseerder met sy beheeralgoritmes is getoets vir verskillende tipes laste met 'n duikgenerator wat ontwikkel is by die Universiteit van Stellenbosch. Die eksperimentele resultate bevestig dit wat verkry is uit die simulasies en wys 'n goeie werkverrigting vir die gespesifiseerde kondisies. 'n Geoptimeerde ontwerp van hierdie duik kompenseerder sal dit 'n koste-effektiewe oplossing maak vir duik kompensasie.

Texto completo da fonteConsidering that SAA is an acute phase protein and increased serum levels are associated with chronic hyperglycemia, insulin resistance and obesity, we first examined the possibility that rSAA could affect proliferation and differentiation 3T3-L1 preadipocytes. 3T3-L1 adipocytes were treated with recombinant human SAA and [methyl-3H]-thymidine incorporation, flow cytometric analysis of cell cycle and viability were performed. Also, gene expression profiles of adipogenic factor were performed during differentiation protocol as well as glucose uptake, GLUT4 gene expression and lipolysis assay. rSAA caused an increment in cell proliferation consisted with FACS analysis with a percentage of cells in the S phase. Cell proliferation was mediated by ERK1/2 signaling pathway and in dose-dependent manner. Also, SAA inhibited differentiation process by decreasing adipogenic genes PPARγ, C/EBPβ, C/EBPα, and proteins FABP4, and perilipin expression. Also, rSAA prevented 2-deoxy-[1,2-3H]-glucose uptake and GLUT4 expression. In addiction, lipolysis was increased favoring insulin resistance in 3T3L1 adipogenic model. In conclusion, it was demonstrated that rSAA enhances proliferation but prevents differentiation in 3T3-L1 adipocytes, supporting a even more complex participation, than previously expected, of inflammatory proteins the adipogenic process.

Texto completo da fonteThe Facilities Management is considered by many authors as an interdisciplinary field devoted to ensure the functionality of the built environment by integrating people, place, process and technology. To develop an architectural model that can be used to deal with management facilities, it is first necessary to establish the role that it must have in business, how to perform these roles and then see if it achieves these requirements. A critical point in developing a model for managing facilities is the lack of an enterprise architecture, due to the building systems and other systems related to infrastructure were designed without a vision of FM on the other hand, these systems usually consist of several heterogeneous technologies in which to function properly must meet requirements such as performance, reliability, portability, scalability and interoperability, among others. This dissertation work proposes to use distributed object architecture to optimize the process of Facilities Management, applied in a real case, especially in a consumer electronics industry of the Industrial Pole of Manaus. The purpose of using this architecture is to reduce complexity through abstraction and separation of design requirements, while directing the steps to be taken by the tasks involved. The proposed method for achieving this goal is the identification of the FM process, specifying where the information obtained will be sorted in order of views using the RM-ODP, and modeling which analyzes the complexities, such as relationships, dependencies and constraints in the process of business, aiming to develop an architecture that will be implemented in the areas of application of the FM process.

Texto completo da fonteLes salpes són tunicats pelàgics marins que han desenvolupat característiques oportunistes per a proliferar quan les condicions són favorables i mantenir-la en períodes adversos. Les altes abundàncies assolides durant un bloom, en combinació amb els seus mecanismes d’alimentació altament eficients, tenen un efecte notable pels ecosistemes així com per a la societat. Tot i que els blooms de salpes són comuns a la costa catalana durant primavera i tardor, les seves causes i el seu paper en l’ecosistema no s’han estudiat mai al mar Català. L’objectiu general de la present tesi és entendre els processos espacials i temporals que condueixen a formar les agregacions de salpes i estimar el seu paper en el mar Català, nord-oest del Mediterrani. Per assolir aquesta fita, s’han combinat models mecanístics (models matricials) i estadístics (GAMs) amb observacions in situ que ens han permès proposar els mecanismes més simples que expliquen el desenvolupament d’un bloom. Hem vist que canvis en la reproducció de les femelles serien els responsables del fre del creixement poblacional durant el període de latència i el detonador del bloom quan les condicions es tornen favorables (Capítol 1). Des d’un punt de vista espacial, l’abundància local de salpes està influenciada principalment per factors físics tot i que les variables biològiques juguen un paper secundari (Capítol 2). Per primer cop s’ha observat la coexistència de patrons diferents de migració vertical diürna (DVM) en una salpa (migració diürna i nocturna en Salpa fusiformis), la qual cosa explica les conclusions contradictòries d’estudis anteriors, però obre noves preguntes sobre els mecanismes de la DVM en salpes. Les dues especies presents en l’estudi produïren impactes tròfics molt diferents: l’impacte de Thalia democratica, va ser quasi negligible degut a la seva baixa abundància mentre que S. fusiformis va ingerir un màxim de 69.92 mgC m-2 dia-1 i defecar 35.76 mgC m-2 dia-1, incrementant considerablement el flux de matèria orgànica cap a l’oceà profund (Capítol 2). Els resultats d’aquesta tesi contribueixen a l’ecologia general de les salpes i ens han portat a la necessitat de plantejar estudis de demografia evolutiva per entendre l’efecte del seu cicle de vida en l’adaptació de la població a canvis ambientals i en el manteniment de la variabilitat genètica entre períodes de latència-bloom.
