TRANSFER OF ANALYTICAL METHODS FOR THE CHARACTERISATION OF NATURAL PRODUCTS TO R&D PROCESSES OF IDOKI

IDOKI SCF Technologies S.L. is a technology-based company, set up on September 2006 in Derio (Biscay) with the main scope of developing extraction and purification processes based on the use of supercritical fluid extraction technology (SFE) in food processing, extraction of natural products and the production of personal care products. IDOKI¿s researchers have been working on many different R&D projects so far, most of them using this technology. However, the optimization of a SFE method for the different matrices cannot be performed unless we have an analytical method for the characterisation of the extracts obtained in each experiment. The analytical methods are also essential for the quality control of the raw materials that are going to be used and also for the final product. This PhD thesis was born to tackle this problem and therefore, it is based on the development of different analytical methods for the characterisation of the extracts and products. The projects that we could include in this thesis were the following: the extraction propolis, the recovery of agroindustrial residues (soy and wine) and the dealcoholisation of wine.On the one hand, for the extraction of propolis, several UV-Vis spectroscopic methods were used in order to measure the antioxidant capacity and the total polyphenol and flavonoid content of the extracts. A SFC method was also developed in order to measure more specific phenolic compounds. On the other hand, for the recovery of agroindustrial residues UV-Vis spectroscopy was used to determine the total polyphenol content and two SFC methods were developed to analyse different phenolic compounds. Extraction methods such as MAE, FUSE and rotary agitation were also evaluated for the characterisation of the raw materials.Finally, for the dealcoholisation of wine, the development of a SBSE-TD-GC-MS and DHS-TD-GC-MS methods for the analysis of aromas and a NIR spectroscopic method for the determination of ethanol content with the help of chemometrics was necessary. Most of these methods are typically used in IDOKI¿s lab as routine analyses apart from others not included in this PhD thesis.

IKASNABAR 2014 International Conference. Microcontents, miniMOOCs and mLearning

[ES]Ikasnabar es una conferencia para hablar de tendencias en educación, sobre las nuevas tecnologías en el ámbito educativo y conocer personas que están generando buenas ideas y prácticas en su quehacer diario. Este libro intenta recoger todo ello con las contribuciones de autores noveles y de renombre que buscan la excelencia en los procesos de enseñanza-aprendizaje. Tres tendencias importantes de aprendizaje se están expandiendo. Microcontenidos, aprendizaje móvil y MOOCs son la cara de una misma moneda: microaprendizaje con contenido rico, abierto y desmenuzado. A medida que el consumo de Internet desde dispositivos móviles aumenta, el aprendizaje móvil con tecnologías como HTML5, software para MOOC, plataformas de contenidos de vídeo, etc., están siendo algunas de las claves de la nueva revolución en el ámbito educativo. El microcontenido hace referencia a los pequeños trozos de información digital en un estado permanente de flujo y circulación. Es a menudo un único tema, limitado en longitud, que se consume rápidamente y con frecuencia limitado por el software o por el dispositivo. Se trata de la puesta en común de recursos. Se basa en la interacción humano-a-humano con los medios de comunicación de Internet. El otro tema central de esta conferencia es el de los MOOC realizados por los profesores que quieren tomar ventaja en el comienzo de esta nueva era de la educación abierta con calidad. MOOCs son, básicamente, cursos abiertos y es necesario recordar los puntos esenciales de este tipo de instrucción. Los miniMOOCs son alternativas con menos horas en el proceso de aprendizaje. Hoy en día, un buen MOOC podrá ser la mejor tarjeta de presentación para profesores, expertos y estudiantes. Vivimos en tiempos de cambio con ámbitos en los que se mezcla el aprendizaje formal e informal, y las universidades y colegios deberíamos estar atentos a esto.

Desafios da formação de sindicalistas na contemporaneidade

Esta dissertação busca refletir sobre as alterações na organização do trabalho na sociedade brasileira do final do século XX, determinadas por políticas de caráter neoliberal, que demandaram alterações também nas abordagens de resistência da classe trabalhadora. Com este intuito, é estudado o processo da assim chamada globalização que trouxe elementos novos para o capitalismo da virada do século: financeirização e liberalização mundial da economia. São analisados os impactos causados no movimento sindical, através do resgate de sua história e seus processos de construção de lideranças, especialmente diante das mudanças trazidas pela reestruturação produtiva na transição híbrida de um modelo essencialmente fordista para outro, flexível, o toyotismo. O estudo foca o exemplo da categoria bancária, utilizando como referencial o Sindicato dos Bancários do Rio de Janeiro. O objeto de estudo centrou-se nos desafios gerados pela conjuntura, notadamente na formação de uma geração de sindicalistas capaz de fazer frente a um capitalismo oxigenado por tal processo de globalização. A fim de entender os desafios da formação de sindicalistas na contemporaneidade, a abordagem empírica baseia-se em entrevistas com dez dirigentes da atual Diretoria Executiva da entidade mencionada, cujo primeiro mandato iniciou nos anos 1990. A orientação metodológica tomou por base a consulta e análise de dados documentais, provenientes majoritariamente do Sindicato dos Bancários do Rio de Janeiro; da Contraf/CUT (Confederação Nacional dos Trabalhadores do Ramo Financeiro da Central Única dos Trabalhadores); do Dieese (Departamento Intersindical de Estatísticas e Estudos Sócio Econômicos), além de literatura especializada referente aos temas afins.

Effect of alkali and alkaline earth fluoride introduction on thermal stability and structure of fluorophosphate glasses

The thermal stability and structure of RF-RF2-AIF(3)-Al(PO3)(3) fluorophosphate glasses were investigated. Analyses of infrared absorbance spectra and Raman spectra reveal that with increasing number of alkali and alkaline earth fluoride components, the sum of P-O-P bond and O-P-O bond increases and glass network is strengthened. Consequently, the inhibition to nucleation and crystallization processes is improved, which is proved by the increment of thermal stability factors AT and S determined by differential scanning calorimetry. In addition, it was found that LiF has poor ability to form glass in univalent alkali fluorides and MgF2 has comparative strong ability to form glass in bivalent alkaline earth fluorides.

Life-stage recruitment models for Atlantic cod (Gadus morhua) and haddock (Melanogrammus aeglefinus) on Georges Bank

Ichthyoplankton surveys have been used to provide an independent estimate of adult spawning biomass of commercially exploited species and to further our understanding of the recruitment processes in the early life stages. However, predicting recruitment has been difficult because of the complex interaction of physical and biological processes operating at different spatial and temporal scales that can occur at the different life stages. A model of first-year life-stage recruitment was applied to Georges Bank Atlantic cod (Gadus morhua) and haddock (Melanogrammus aeglefinus) stocks over the years 1977–2004 by using environmental and densitydependent relationships. The best lifestage mortality relationships for eggs, larvae, pelagic juveniles, and demersal juveniles were first determined by hindcasting recruitment estimates based on egg and larval abundance and mortality rates derived from two intensive sampling periods, 1977–87 and 1995–99. A wind-driven egg mortality relationship was used to estimate losses due to transport off the bank, and a wind-stress larval mortality relationship was derived from feeding and survival studies. A simple metric for the density-dependent effects of Atlantic cod was used for both Atlantic cod and haddock. These life stage proxies were then applied to the virtual population analysis (VPA) derived annual egg abundances to predict age-1 recruitment. Best models were determined from the correlation of predicted and VPA-derived age-1 abundance. The larval stage was the most quantifiable of any stage from surveys, whereas abundance estimates of the demersal juvenile stage were not available because of undersampling. Attempts to forecast recruitment from spawning stock biomass or egg abundance, however, will always be poor because of variable egg survival.

Quantum Simulator for Transport Phenomena in Fluid Flows

Transport phenomena still stand as one of the most challenging problems in computational physics. By exploiting the analogies between Dirac and lattice Boltzmann equations, we develop a quantum simulator based on pseudospin-boson quantum systems, which is suitable for encoding fluid dynamics transport phenomena within a lattice kinetic formalism. It is shown that both the streaming and collision processes of lattice Boltzmann dynamics can be implemented with controlled quantum operations, using a heralded quantum protocol to encode non-unitary scattering processes. The proposed simulator is amenable to realization in controlled quantum platforms, such as ion-trap quantum computers or circuit quantum electrodynamics processors.

Timing and duration of mating and brooding periods of Atka mackerel (Pleurogrammus monopterygius) in the North Pacific Ocean

The timing and duration of the reproductive cycle of Atka mackerel (Pleurogrammus monopterygius) was validated by using observations from time-lapse video and data from archival tags, and the start, peak, and end of spawning and hatching were determined from an incubation model with aged egg samples and empirical incubation times ranging from 44 days at a water temperature of 9.85°C to 100 days at 3.89°C. From June to July, males ceased diel vertical movements, aggregated in nesting colonies, and established territories. Spawning began in late July, ended in mid-October, and peaked in early September. The male egg-brooding period that followed continued from late November to mid-January and duration was highly dependent on embryonic development as affected by ambient water temperature. Males exhibited brooding behavior for protracted periods at water depths from 23 to 117 m where average daily water temperatures ranged from 4.0° to 6.2°C. Knowledge about the timing of the reproductive cycle provides a framework for conserving Atka mackerel populations and investigating the physical and biological processes influencing recruitment.

A Demographic Profile of Participants in Two Gulf of Mexico Inshore Shrimp Fisheries and Their Response to the Texas Closure

A social study of the shrimp fisheries of Galveston Bay, Tex., and Calcasieu Lake, La., was made during the summer of 1987 to examine the impacts of the seasonal closure of the Federal waters off Texas and to understand the infrastructure and demographic processes of these two diverse fisheries. Survey instruments were administered to 159 shrimp boat captains: 89 from Galveston Bay and 70 from Calcasieu Lake. Shrimp-house owners were interviewed in each region as well. The results suggest that the inshore fisheries (i.e., shrimpers and shrimp houses) are distinct from the offshore fisheries. The infrastructure of the two inshore fisheries examined differ in that the market distribution of shrimp from Galveston Bay was more diffuse than from Calcasieu Lake. Much more of the shrimp harvested from Galveston Bay was channelled into the surrounding community than from Calcasieu Lake. The distribution of age,years as a commercial fisherman, and family involvement in fishing suggest that participation in Calcasieu Lake's and Galveston Bay's inshore fisheries have expanded concurrent with declining economies. While overall the Texas closure had little impact on either of the inshore fisheries, the Galveston Bay shrimpers experienced more of a direct impact on their livelihood than Calcasieu Lake shrimpers.

The review of recent advances in fish genetics and biotechnology

Great advances have been, and are being made in our knowledge of the genetics and molecular biology (including genomics, proteomics and structural biology). Global molecular profiling technologies such as microassays using DNA or oligonucleotide chip, and protein and lipid chips are being developed. The application of such biotechnological advances are inevitable in aquaculture in the areas of improvement of aquaculture stocks where many molecular markers such as RFLPs, AFLDs and RAPD are now available for genome analysis, finger printing and genetic linkage mapping. Transgenic technology has been developed in a number of fish species and research is being pursed to produce transgenic fish carrying genes that encode antimicrobial peptides such as lysozyme thereby achieving disease resistance in fish. Also it is a short cut to achieving genetic change for fast growth and other desirable traits like early sexual maturity, temperature tolerance and feed conversion efficiency.

Resilient livelihoods and food security in coastal aquatic agricultural systems: Investing in transformational change

Aquatic agricultural systems (AAS) are diverse production and livelihood systems where families cultivate a range of crops, raise livestock, farm or catch fish, gather fruits and other tree crops, and harness natural resources such as timber, reeds, and wildlife. Aquatic agricultural systems occur along freshwater floodplains, coastal deltas, and inshore marine waters, and are characterized by dependence on seasonal changes in productivity, driven by seasonal variation in rainfall, river flow, and/or coastal and marine processes. Despite this natural productivity, the farming, fishing, and herding communities who live in these systems are among the poorest and most vulnerable in their countries and regions. This report provides an overview of the scale and scope of development challenges in coastal aquatic agricultural systems, their significance for poor and vulnerable communities, and the opportunities for partnership and investment that support efforts of these communities to secure resilient livelihoods in the face of multiple risks.

Políticas públicas de avaliação para a educação superior no Brasil: autonomia e produção do conhecimento

A tese aborda as políticas públicas de avaliação para a educação superior no Brasil, desde o seu surgimento, indicado na Reforma Universitária de 1968 e sua efetivação a partir da década de 1980, no Programa de Avaliação da Reforma Universitária PARU e no Grupo de Estudos da Reforma da Educação Superior GERES, ambos com a função de avaliar a Universidade brasileira. Contextualiza a sua institucionalização na década de 1990, por meio do Programa de Avaliação Institucional das Universidades Brasileiras PAIUB, do Exame Nacional de Cursos ENC ou Provão, com enfoque na última e atual política, o Sistema Nacional de Avaliação da Educação Superior SINAES e, neste, a avaliação institucional. O objetivo que motivou a produção desta tese foi conseguir clareza sobre as políticas públicas de avaliação para a educação superior no Brasil, especificamente o processo de implantação e implementação da avaliação institucional no período do SINAES na UNIOESTE, bem como, seus desdobramentos no que concerne à autonomia e à produção do conhecimento. Para tanto, foi preciso percorrer meandros do tema, historicizando as políticas públicas de avaliação para a educação superior no Brasil; identificando, examinando e discutindo os processos de implantação e implementação da avaliação institucional na UNIOESTE PR; analisando e discutindo os desdobramentos da avaliação institucional no que concerne à autonomia e à produção do conhecimento na UNIOESTE. A metodologia se constituiu de pesquisa bibliográfica, análise documental e estudo do processo de implantação e implementação do SINAES e também de seus desdobramentos na questão da autonomia e produção do conhecimento em uma universidade pública estadual, a UNIOESTE. Sobre os desdobramentos do SINAES na questão da autonomia e da produção do conhecimento, infere-se que as medidas das políticas públicas de avaliação para a educação superior interferem e impactam a universidade, imprimindo autonomia e produção do conhecimento na medida/lógica necessária para dar vigor a determinada conjuntura societária. No SINAES, a Autoavaliação Institucional é um mecanismo falho, inoperante, que não atende às demandas da comunidade acadêmica e, ainda, que não atinge a sua finalidade profícua, a melhoria da universidade. Dessa maneira, no contexto atual, a universidade se consome em seu papel e função social, dando espaço e força à conformação da universidade às demandas e determinações do capital. A Autoavaliação Institucional precisa ser analisada em suas premissas e no formato que se incorpora ao SINAES, mas não somente isso isoladamente, e, sim, todo o SINAES, enquanto uma política pública de avaliação, para que seja direcionada em favor da universidade e da sociedade brasileira

River Eden RHS and geomorphology evaluation. Final report October 2001

This is the River Eden RHS and geomorphology evaluation: Final report October 2001 produced by the Environment Agency North West in 2001. This report analysed the River Habitat Survey (RHS) and geomorphology data to evaluate the level of habitat quality and the geomorphological characteristics of the River Eden and sub-catchments. RHS data and geomorphological assessment data was collected within the study areas by CEH and Fluvial Environmental Services Ltd. The River Eden and its sub-catchments are being considered as a Special Area for Conservation (SAC) due to the presence of habitat types and species, which are rare or threatened within Europe. The purpose of the project is to provide an overview of the state of the catchment in terms of river habitats and geomorphological processes in order to aid the derivation of sound management for this proposed SAC.The aim of this report was to determine the state of the environment within the Eden and sub-catchments and identify the main pressures on the system in order to derive sound management options.

An ecological characterization of the Stellwagen Bank National Marine Sanctuary Region: oceanographic, biogeographic, and contaminants assessment

The mission of NOAA’s National Marine Sanctuary Program (NMSP) is to serve as the trustee for a system of marine protected areas, to conserve, protect, and enhance their biodiversity, ecological integrity, and cultural legacy while facilitating compatible uses. Since 1972, thirteen National Marine Sanctuaries, representing a wide variety of ocean environments, have been established, each with management goals tuned to their unique diversity. Extending from Cape Ann to Cape Cod across the mouth of Massachusetts Bay, Stellwagen Bank National Marine Sanctuary (NMS) encompasses 2,181 square kilometers of highly productive, diverse, and culturally unique Federal waters. As a result of its varied seafloor topography, oceanographic conditions, and high primary productivity, Stellwagen Bank NMS is utilized by diverse assemblages of seabirds, marine mammals, invertebrates, and fish species, as well as containing a number of maritime heritage resources. Furthermore, it is a region of cultural significance, highlighted by the recent discovery of several historic shipwrecks. Officially designated in 1992, Stellwagen Bank became the Nation’s twelfth National Marine Sanctuary in order to protect these and other unique biological, geological, oceanographic, and cultural features of the region. The Stellwagen Bank NMS is in the midst of its first management plan review since designation. The management plan review process, required by law, is designed to evaluate, enhance, and guide the development of future research efforts, education and outreach, and the management approaches used by Sanctuaries. Given the ecological and physical complexity of Stellwagen Bank NMS, burgeoning anthropogenic impacts to the region, and competing human and biological uses, the review process was challenged to assimilate and analyze the wealth of existing scientific knowledge in a framework which could enhance management decision-making. Unquestionably, the Gulf of Maine, Massachusetts Bay, and Stellwagen Bank-proper are extremely well studied systems, and in many regards, the scientific information available greatly exceeds that which is available for other Sanctuaries. However, the propensity of scientific information reinforces the need to utilize a comprehensive analytical approach to synthesize and explore linkages between disparate information on physical, biological, and chemical processes, while identifying topics needing further study. Given this requirement, a partnership was established between NOAA’s National Marine Sanctuary Program (NMSP) and the National Centers for Coastal Ocean Science (NCCOS) so as to leverage existing NOAA technical expertise to assist the Sanctuary in developing additional ecological assessment products which would benefit the management plan review process.

Atmospheric chlorofluoromethanes as tracers of ocean circulation and mixing: measurement and calibration techniques and studies in the Greenland and Norwegian seas

EXTRACT (SEE PDF FOR FULL ABSTRACT): An analytical system was designed and constructed for the rapid and accurate shipboard measurement of anthropogenic chlorofluoromethanes in seawater and in air, using electron capture gas chrometography. The distribution of these compounds in the marine atmosphere and the water column in the Greenland and Norwegian seas were studied during February and March, 1982. The compounds, dissolved in the ocean from the atmosphere, can be used as tracers of subsurface ocean circulation and mixing processes.

Addressing the cognitive and social influence inhibitors during the ideation stages of technology roadmapping workshops

Technology roadmapping workshops are essentially a social mechanism for exploring, creating, shaping and implementing ideas. The front-end of a roadmapping session is based on brainstorming in order to tap into the group's diverse knowledge. The aim of this idea stimulation activity is to capture and share as many perspectives as possible across the full scope of the area of interest. The premise to such group brainstorming is that the sharing and exchange of ideas leads to cognitive stimulation resulting in a greater overall group idea generation performance in terms of the number, variety and originality of ideas. However, it must be recognized that the ideation stage in a roadmapping workshop is a complex psychosocial phenomenon with underlying cognitive and social processes. Thus, there are downsides to group interactions and these must be addressed in order to fully benefit from the power of a roadmapping workshop. This paper will highlight and discuss the key cognitive and social inhibitors involved. These include: production blocking, evaluation apprehension, free riding/social loafing, low norm setting/matching. Facilitation actions and process adjustments to counter such negative factors will be identified so as to provide a psychosocial basis for improving the running of roadmapping workshops. © 2009 PICMET.
