Enrichment of a PHA producing microbial community in a continuous bioreactor setup

Polyhydroxyalkanoates (PHAs) are biosynthetic polyesters, biodegradable and biocompatible making them of great interest for industrial purposes. The use of low value substrates with mixed microbial communities (MMC) is a strategy currently used to decrease the elevated PHA production costs. PHA production process requires an important step for selection and enrichment of PHA-storing microorganisms which is usually carried out in a Sequencing Batch Reactor (SBR). The aim of this study was to optimize the PHA accumulating culture selection stage using a 2-stage Continuous Stirrer Tank Reactor (CSTR) system. The system was composed by two separate feast and famine bioreactors operated continuously, mimicking the feast and famine phases in a SBR system. Acetate was used as carbon source and biomass seed was highly enriched in Plasticicumulans acidivorans obtained from activated sludge. The system was operated under two different sets of conditions (setup 1 and 2), maintaining a system total retention time of 12 hours and an OLR of 2.25 Cmmol/L.h-1. An average PHB-content of 3.3 % wt was obtained in setup 1 and 4.8% wt in setup 2. Several other experiments were performed in order to better understand the continuous system behaviour, using biomass from the continuous system. With the fed-batch experiment a maximum of 8.1% PHB was stored and the maximum substrate uptake and specific growth rates obtained in the growth experiment (1.15 Cmol Cmol-1.h-1 and 0.53 Cmol Cmol-1.h-1) were close to the ones from continuous system (1.12 Cmol Cmol-1.h-1 and 0.59 Cmol Cmol-1.h-1). The microbial community was characterized trough microscopic visualization, Denaturing Gradient Gel Electrophoresis (DGGE) analysis and Fluorescent in situ hybridization (FISH). The last studied performed mimicked the continuous system by building up a SBR system with all the same operational conditions while adding an extra acetate dosage during the 12 h cycle, simulating the substrate passing from the feast to the famine reactors under continuous operation. It was shown that possibly the continuous system was not able to efficiently select for PHB storing organisms under the operational conditions imposed, although the selected culture was capable of consuming the substrate and grow fast. This main conclusion might have resulted from two major factors affecting the system performance: the ammonium concentration in the Feast reactor and the amount of substrate leaching from the Feast to the Famine reactor.

Long-term characterization of air lime mortars with ceramic waste

Due to their exposure to environmental conditions, outer coatings composed by render and painting system are usually the first construction elements to deteriorate and require intervention. A correct conservation and rehabilitation of these materials is fundamental once they provide protection to other façade materials. It is known that old mortar renders were essentially air lime based mortars. To maintain the integrity of the whole wall-render elements, the image of the building and to avoid accelerated degradation, conservation and rehabilitation must be implemented with compatible mortars. As that, lime based mortars would be preferable. It was also common, in ancient renders, the incorporation of ceramic residues, which is, nowadays, an abundant material, especially in Central Region of Portugal. The reuse of these materials has great relevance once their landfilling causes serious environmental issues. In an attempt to combine the environmental and technical advantages of the use of ceramic waste in mortars’ production for rehabilitation purposes, a research has been developed at the University of Coimbra, in cooperation with Nova University of Lisbon, on the long term behaviour of air lime mortars with ceramic residues. In this paper the most significant up to one year results of an experimental campaign with air lime mortars with 1:3 and 1:2 volumetric proportions and ceramic residues are presented.

Satisfação profissional dos médicos dentistas na utilização do cheque-dentista : um estudo exploratório no concelho de Lisboa

RESUMO - A satisfação profissional é um fenómeno amplamente estudado e esse interesse decorre da influência que a mesma pode exercer sobre o trabalhador, afetando a sua saúde, atitudes, comportamento profissional e social, com repercussões tanto para a sua vida privada como para as organizações. Considerando a tendência mundial de se aproximarem os perfis da profissão para um perfil único e de que a investigação sobre a satisfação profissional dos médicos dentistas em vários países estar presentemente a ser divulgada, seria importante avaliar a situação em Portugal para fins comparativos. O presente estudo teve como objetivo investigar o grau de satisfação profissional dos médicos dentistas na utilização do cheque-dentista no concelho de Lisboa, procurando estabelecer relações entre as diferentes dimensões da satisfação profissional e variáveis socioprofissionais. Um questionário de autopreenchimento foi enviado por e-mail para as clínicas onde os médicos dentistas trabalham, num total de 99 obtendo-se uma taxa de resposta de 24,2%. Verificou-se que em relação à satisfação profissional em geral nas várias dimensões questionadas, é a relação profissional/paciente que os médicos dentistas consideram como mais importante logo seguida da realização pessoal e profissional. Como menos importante os médicos dentistas referiram o status/prestígio e a segurança profissional. Já no campo da satisfação profissional no âmbito do cheque-dentista concluiu-se que mais próximo do grau de satisfeito se encontra a relação estabelecida com o paciente assim como a relação de trabalho com a equipa. No grau de satisfação mais baixo, de total insatisfação encontra-se o número de tratamentos que são permitidos efetuar em cada cheque-dentista e um último lugar encontrase o valor remuneratório do cheque-dentista. Comparando a satisfação profissional com o cheque-dentista entre géneros, verificou-se que apenas na dimensão do valor remuneratório do cheque-dentista existem diferenças estatisticamente significativas (p=0,026), sendo que o género feminino demonstra maior satisfação que o género masculino. O número de participantes não foi suficiente para que se possa generalizar os resultados para a população. É necessária a realização de mais estudos neste âmbito com um maior número de profissionais de forma a que os resultados sejam estatisticamente significativos.

O impacto da Rede Nacional de Cuidados Continuados Integrados (RNCCI) na demora média hospitalar

RESUMO - Enquadramento: O envelhecimento dos indivíduos nos países mais desenvolvidos e o aumento da incidência de doenças crónicas associadas a estados de dependência e incapacidade têm contribuído para o desenho e implementação de novas políticas de saúde e sociais. Assiste-se, por isso, atualmente, a uma mudança no paradigma da procura de cuidados de saúde, sendo crescente a procura de cuidados de longa duração ou cuidados continuados. O desenvolvimento e implementação de novos modelos de prestação de cuidados de saúde pretendem dar resposta à crescente procura de cuidados continuados, bem como promover a eficiência dos serviços e a disponibilização de camas nos hospitais, retirando dos serviços de agudos as pessoas que não necessitam de cuidados hospitalares, mas sim de cuidados continuados. Neste contexto foi criada em Portugal a Rede Nacional de Cuidados Continuados Integrados (RNCCI), como resposta ao aumento do número de pessoas em situação de dependência, e que necessitam tanto de cuidados de saúde como sociais, e à necessidade de reorganizar e promover a eficiência dos serviços de internamento hospitalar. Objetivo: Determinar o impacto da RNCCI na demora média hospitalar, no período de tempo compreendido entre 1 de Janeiro de 2009 e 31 de Junho de 2011. Métodos: O estudo realizado, com base na revisão da literatura, descreve os principais aspectos referentes ao envelhecimento dos indivíduos e aos cuidados continuados. Foram descritos diferentes modelos e programas organizacionais de prestação de cuidados continuados e o seu impacto na demora média hospitalar. Foi determinada a população em estudo no período de tempo compreendido entre 1 de Janeiro de 2009 e 31 de Junho de 2011. A população foi caraterizada de acordo com o ano e distribuída por dez trimestres para melhor tratamento estatístico e leitura dos dados. Foi considerado o sexo e a faixa etária dos indivíduos sinalizados, de acordo com o GDH de internamento hospitalar e respetiva sub-região de saúde. Foi comparada por trimestre a demora média dos internamentos hospitalares e a demora média hospitalar dos episódios referenciados a nível nacional e ao nível das sub-regiões de saúde. Foram caraterizados os GDH que representam 50% das sinalizações. Foram analisados, por semestre, os três GDH com maior número de referenciações para a RNCCI de acordo com as diferentes regiões de saúde, comparando as respetivas demoras médias nacionais e regionais. Resultados: No periodo de tempo em análise foi verificado que a população com maior utilização dos serviços da RNCCI encontra-se na faixa etária entre 65 ou mais anos, com 79,4% do total de sinalizações efetuadas. Tendo 50% das sinalizações sido referentes aos GDH 14, GDH 211, GDH 533, GDH 818, GDH 810 e GDH 209. Foi apurada uma demora média nacional compreendida entre os 7,3 dias e os 7,7 dias, comparativamente a uma demora média dos episódios referenciados para a RNCCI compreendida entre os 21,9 dias e os 33 dias, para o mesmo período de tempo. Em termos regionais a região de LVT apresenta os valores de demora média mais elevados, com um intervalo entre os 28,8 dias e os 50,3 dias de demora média. Para o GDH 14 foi observada uma demora média dos episódios referenciados compreendida entre os 14,4 dias e os 26,7 dias. No mesmo período de tempo o a demora média nacional para o mesmo GDH situava-se entre os 9,8 dias e os 10,2 dias. Para o GDH 211 foi observada uma demora média dos episódios referenciados compreendida entre os 17,2 dias e os 28,9 dias. Comparativamente a demora média nacional para o mesmo GDH situava-se entre os 12,5 dias e os 13,5 dias. Para o GDH 533 foi observada uma demora média dos episódios referenciados compreendida entre os 23,3 dias e os 52,7 dias. Comparativamente, no mesmo período de tempo, a demora média nacional para o mesmo GDH situava-se entre os 18,7 dias e os 19,7 dias. Conclusões: Foi possível concluir, quanto ao impacto da RNCCI na demora média hospitalar, que a demora média dos episódios referenciados para a Rede é superior à demora média nacional em todo o período de tempo em análise. Relativamente à demora média dos GDH com maior número de referenciações, os GDH 14, 211 e 533, verifica-se que todos eles apresentam uma demora média de referenciação superior à demora média nacional, e demora média regional para o mesmo GDH, em todo o período de tempo do estudo. Ou seja, foi possível verificar que a demora média para indivíduos com o mesmo GDH é superior nos que são referenciados para a RNCCI.

Of Structural Denial: A Narratological Study of the Structural Disintegration of the Novel Form

If an opening to the argument of this dissertation is of imperative necessity, one might tentatively begin with Herbert Quain, born in Roscommon, Ireland, author of the novels The God of the Labyrinth (1933) and April March (1936), the short-story collection Statements (1939), and the play The Secret Mirror (undated). To a certain extent, this idiosyncratic Irish author, who hailed from the ancient province of Connacht, may be regarded as a forerunner of the type of novels which will be considered in this dissertation. Quain was, after all, the unconscious creator of one of the first structurally disintegrated novels in the history of western literature, April March. His first novel, The God of the Labyrinth, also exhibits elements which are characteristic of structurally disintegrated fiction, for it provides the reader with two possible solutions to a mysterious crime. As a matter of fact, one might suggest that Quain’s debut novel offers the reader the possibility to ignore the solution to the crime and carry on living his or her readerly life, turning a blind eye to the novel itself. It may hence be argued that Quain’s first novel is in fact a compound of three different novels. It is self-evident that the structure of Quain’s oeuvre is of an experimental nature, combining geometrical precision with authorial innovation, and one finds in it a higher consideration for formal defiance than for the text itself. In other words, the means of expression are the concern of the author and not, interestingly, the textual content. April March, for example, is a novel which regresses back into itself, its first chapter focussing on an evening which is preceded by three possible evenings which, in turn, are each preceded by three other, dissimilar, possible evenings. It is a novel of backward-movement, and it is due to this process of branching regression that April March contains within itself at least nine possible novels. Structure, therefore, paradoxically controls the text, for it allows the text to expand or contract under its formal limitations. In other words, the formal aspects of the novel, usually associated with the restrictive device of a superior design, contribute to a liberation of the novel’s discourse. It is paradoxical only in the sense that the idea of structure necessarily entails the fixation of a narrative skeleton that determines how plot and discourse interact, something which Quain flouts for the purposes of innovation. In this sense, April March’s convoluted structure allows for multiple readings and interpretations of the same text, consciously germinating narratives within itself, producing different texts from a single, unique source. Thus, text and means of expression are bonded by a structural design that, rather than limiting, liberates the text of the novel.

Tool for spatial and dynamic representation of artistic performances

This proposal aims to explore the use of available technologies for video representation of sets and performers in order to serve as support for composition processes and artistic performer rehearsals, while focusing in representing the performer’s body and its movements, and its relation with objects belonging to the three-dimensional space of their performances. This project’s main goal is to design and develop a system that can spatially represent the performer and its movements, by means of capturing processes and reconstruction using a camera device, as well as enhance the three-dimensional space where the performance occurs by allowing interaction with virtual objects and by adding a video component, either for documentary purposes, or for live performances effects (for example, using video mapping video techniques in captured video or projection during a performance).

Estudo sobre o consumo de tabaco entre os adolescentes da Ilha Terceira

RESUMO - O objetivo deste estudo foi conhecer o comportamento face ao consumo de tabaco reportado pelos adolescentes escolarizados da ilha Terceira e caracterizar alguns fatores associados. O estudo realizado assumiu uma metodologia de investigação observacional, descritiva, quantitativa e de carácter transversal. Os dados foram recolhidos no ano letivo 2012/2013, nos alunos do 9.º ano de escolaridade, através da aplicação de um questionário de autopreenchimento, anónimo e voluntário, em contexto de sala de aula. A amostra foi constituída por 323 adolescentes, 142 do sexo masculino e 181 do sexo feminino, com idade média de 14,71 anos. Verificou-se que cerca de 16,9% dos adolescentes consome tabaco regularmente, 6,6% ocasionalmente e 76,6% não fuma. Mais de metade dos adolescentes já experimentou fumar tabaco (56%), sendo a idade média de experimentação de 12,49 anos. A maioria dos adolescentes que experimentaram fumar referiram tê-lo feito por curiosidade (84,7%) e, sobretudo, na companhia dos amigos (83,1%). As variáveis associadas ao comportamento tabágico foram: o desempenho escolar, os hábitos tabágicos dos amigos, a permissividade dos pais para se fumar em casa, a frequência à exposição ao tabaco em casa, os conhecimentos da “impotência sexual” como consequência do consumo de tabaco, conhecimento dos danos na saúde em frequentar ambientes com fumo e a crença de que os jovens fumadores são mais atraentes. Os resultados mostram a elevada necessidade de serem desenvolvidas estratégias de prevenção e controlo do tabagismo entre os adolescentes da ilha Terceira.

Investing beyond the core: The case of Soares da Costa

This study aims to analyze how Grupo Soares da Costa, a diversified group centered on construction, behaved in terms of strategy to the current crisis. More specifically, it purposes to understand why Soares da Costa was forced to abandon its strategic plan “Ambições Renovadas”, which was about diversification and internationalization, to decide to focus on it core business. This study uses a SWOT analysis, the examination of the strategic plans and annual reports and the conclusions of two interviews that were carried out. Being the construction sector such a traditional and significant sector to the Portuguese economy, it is important to understand what a company can do to overcome such circumstances. To deal with all the negative circumstances, Soares da Costa should give priority to projects that require low levels of initial capital and diversify geographically to markets with similar characteristics of Angola and Mozambique, where Soares da Costa already excels.

Statistics as a basis for discrimination in the insurance business

The European Court of Justice has held that as from 21 December 2012 insurers may no longer charge men and women differently on the basis of scientific evidence that is statistically linked to their sex, effectively prohibiting the use of sex as a factor in the calculation of premiums and benefits for the purposes of insurance and related financial services throughout the European Union. This ruling marks a sharp turn away from the traditional view that insurers should be allowed to apply just about any risk assessment criterion, so long as it is sustained by the findings of actuarial science. The naïveté behind the assumption that insurers’ recourse to statistical data and probabilistic analysis, given their scientific nature, would suffice to keep them out of harm’s way was exposed. In this article I look at the flaws of this assumption and question whether this judicial decision, whilst constituting a most welcome landmark in the pursuit of equality between men and women, has nonetheless gone too far by saying too little on the million dollar question of what separates admissible criteria of differentiation from inadmissible forms of discrimination.

Da valoração de gravações e fotografias obtidas por particulares no processo penal

Recordings and photographs obtained by private individuals can be two of the most relevant evidences in helping finding the truth; however, they can also conflict with fundamental rights such as privacy, spoken word or image of the targets. It is not enough that only the violation of the right to privacy is withdrawn because rights to spoken word or image, unattached from the first one, show up independently as the main violated rights and are criminally protected in article 199º of the criminal code. Its use as evidence is, on a first moment, dependent on the private's conduct lawfulness, as it is stated in article 167º of the criminal procedure code. In order to consider its lawfulness, and accept its use as evidence, portuguese higher courts have been defending constructions mostly based on legal causes of defense. Although agreeing with a more flexible position of weighing all the interests at stake instead of denying its use as evidence, we believe notwithstanding that some of these solutions are misleading and shall not be spared from critics. Lastly, even if we reach a positive conclusion about the lawfulness of obtaining and using recordings and photogtaphs carried out to court by private individuals, they must not be however automatically admitted as evidence, still being necessary to proceed to a separate weighting, within the criminal procedure and its own legal rules, about their real purposes in the case.

Ressocialização no meio prisional

This paper examine the purpose of rehabilitation while main purpose of imprisonment application, and the divergence between its central role assumed in legislation and what is being practiced in the institutional dimension. This study aims to determine the expected outcome of this dialectical opposition, in pursuit of preventive purposes that guide the criminal reactions of Portuguese criminal - legal system. To this end, the sentence of imprisonment shall be framed in the main politico- criminal traits of our country, analyzing the standards and principles that underlie and underpin our legal – criminal system. The guiding principles of the prison sentence and the respective legislation will be presented, such as the prison system and treatment provided to achieve the above desideratum. Finally material factors and legislative contradictions that oppose the rehabilitation in prisons will be presented. The dissertation does not intend to expose the solution to this paradox insurmountable, but rather present the main factors that hinder the achievement of the objectives intended to be achieved with the prison sentence.

A harmonização fiscal europeia

With this dissertation we aim to analyze the most relevant aspects of the excise duties harmonized regime, considering Community origins, but having also in attention all legal specifications of its implementation in Portugal. The legal regime of excise duties is presented as an ambitious theme, considering the challenge of different branches of law that influence this subject, such as Tax, Economic and Community laws, the inescapable influence of customs procedures, or regarding environmental objectives. In the European context, the harmonization of excise duties was seen as a condition for the implementation of the internal market, contributing to undo secular tax barriers between Member States and, since so, ensure fair competition and free movement of services and goods. Along with VAT, the excise duties harmonization process could represent a potential European tax system, essential for a full and integrated single market. In this context, it is essential to pay special attention to specific characteristics of excise duties regime, such as ‘duty suspension arrangement’ applicable during the production phase, storage and movement in certain conditions. The growing importance of excise duties, as for revenue or extra-fiscal purposes, recommends new academic studies on this subject, seeking new opportunities and challenges.

Assessment by doppler ultrasound of entheseal lesions in spondyloarthritis : a longitudial study to determine structural damage and disease activity lesions

RESUMO: Enthesitis is the hallmark of spondyloarthritis (SpA), and is observed in all subtypes. Wide information on SpA abnormalities, including synovitis, tendinitis and enthesitis, can be efficiently perceived by Doppler ultrasound. Furthermore, several studies on imaging of enthesis showed that imaging techniques are better than clinical examination to detect enthesis alterations; and vascularized enthesitis detected by Doppler ultrasound appears to be a valuable diagnostic tool to confirm SpA diagnosis. However, data published until now concerning entheseal elementary alterations that characterize SpA enthesitis (enthesis inflammatory activity) or enthesopathy (permanent structural changes) reflect rather the authors’ empiric opinion than a methodological validation process. In this sense it seems crucial to identify elementary entheseal lesions associated with activity or damage, in order to improve monitoring and treatment response in SpA patients. The development of better assessment tools is today a challenge and a need in SpA. The first study of this thesis focused on the analysis of the reliability of inter-lector and inter-ultrasonography equipment of Madrid sonography enthesitis index (MASEI). Fundamental data for the remaining unrolling project validity. In the second and third studies we concerned about two entheseal elemental lesions: erosions and bursa. In literature erosions represent a permanent structural damage, being useful for monitoring joint injury, disease activity and therapeutic response in many rheumatic diseases; and to date, this concept has been mostly applied in rheumatoid arthritis (RA). Unquestionably, erosion is a tissue-related damage and a structural change. However, the hypothesis that we decided to test was if erosions represent a permanent structural change that can only grow and worsen over time, as occurs in RA, or a transitory alteration. A longitudinal study of early SpA patients was undertaken, and the Achilles enthesis was used as a model. Our results strongly suggested that previously detected erosions could disappear during the course of the disease, being consistent with the dynamic behavior of erosion over time. Based on these striking results it seems reasonable to suggest that the new-bone formation process in SpA could be associated with the resolution of cortical entheseal erosion over time. These results could also be in agreement with the apparent failure of anti-tumor necrosis factor (TNF) therapies to control bone proliferation in SpA; and with the relation of TNF-α, Dickkopf-related protein 1 (Dkk-1) and the regulatory molecule of the Wnt signaling pathway in the bone proliferation in SpA. In the same model, we then proceeded to study the enthesis bursa. Interestingly, the Outcome Measures in Rheumatology Clinical Trials (OMERACT) enthesopathy definition does not include bursa as an elementary entheseal lesion. Nonetheless, bursa was included in 46% of the enthesis studies in a recently systematic literature review, being in agreement with the concept of “synovio-entheseal complex” that includes the link between enthesitis and osteitis in SpA. It has been clarified in recent data that there is not only a close functional integration of the enthesis with the neighboring bone, but also a connection between enthesitis and synovitis. Therefore, we tried to assess the prevalence and relevance of the bursa-synovial lesion in SpA. Our findings showed a significant increase of Achilles bursa presence and thickness in SpA patients compared to controls (healthy/mechanical controls and RA controls). These results raise awareness to the need to improve the enthesopathy ultrasonographic definition. In the final work of this thesis, we have explored new perspectives, not previously reported, about construct validity of enthesis ultrasound as a possible activity outcome in SpA. We performed a longitudinal Achilles enthesis ultrasound study in patients with early SpA. Achilles ultrasound examinations were performed at baseline, six- and twelve-month time periods and compared with clinical outcome measures collected at basal visit. Our results showed that basal erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) are higher in patients with Doppler signal in enthesis, and even that higher basal ESR, CRP and Ankylosing Spondylitis Disease Activity Score (ASDAS) predicted a higher Doppler signal (an ultrasound alteration accepted as representative of inflammation) six months later. Patients with very high disease activity assessed by ASDAS (>3.5) at baseline had significantly higher Achilles total ultrasound score verified at the same time; and ASDAS <1.3 predicted no Doppler signal at six and twelve months. This seems to represent a connection between classical biomarkers and clinical outcomes associated with SpA activity and Doppler signal, not only at the same time, but also for the following months. Remarkably, patients with inactive disease (ASDAS < 1.3) at baseline had no Doppler signal at six and twelve months. These findings reinforce the potential use of ultrasound related techniques for disease progression assessment and prognosis purposes. Intriguingly, Ankylosing Spondylitis Disease Activity Index (BASDAI) didn’t show significant differences between different cut-offs concerning ultrasound lesions or Doppler signal, while verified with ASDAS. These results seem to indicate that ASDAS reflects better than BASDAI what happens in the enthesis. The work herein discussed clearly shows the potential utility of ultrasound in enthesis assessment in SpA patients, and can be important for the development of ultrasound activity and structural damage scores for diagnosis and monitoring purposes. Therefore, local promotion of this technique constitutes a medical intervention that is worth being tested in SpA patients for diagnosis, monitoring and prognosis purposes.

DYNAMOD – A dynamic agent based modelling framework for digital businesses

Digital Businesses have become a major driver for economic growth and have seen an explosion of new startups. At the same time, it also includes mature enterprises that have become global giants in a relatively short period of time. Digital Businesses have unique characteristics that make the running and management of a Digital Business much different from traditional offline businesses. Digital businesses respond to online users who are highly interconnected and networked. This enables a rapid flow of word of mouth, at a pace far greater than ever envisioned when dealing with traditional products and services. The relatively low cost of incremental user addition has led to a variety of innovation in pricing of digital products, including various forms of free and freemium pricing models. This thesis explores the unique characteristics and complexities of Digital Businesses and its implications on the design of Digital Business Models and Revenue Models. The thesis proposes an Agent Based Modeling Framework that can be used to develop Simulation Models that simulate the complex dynamics of Digital Businesses and the user interactions between users of a digital product. Such Simulation models can be used for a variety of purposes such as simple forecasting, analysing the impact of market disturbances, analysing the impact of changes in pricing models and optimising the pricing for maximum revenue generation or a balance between growth in usage and revenue generation. These models can be developed for a mature enterprise with a large historical record of user growth rate as well as for early stage enterprises without much historical data. Through three case studies, the thesis demonstrates the applicability of the Framework and its potential applications.
