Yes / The process of capturing and storing carbon dioxide (CCS) was previously considered a crucial and time-sensitive approach for diminishing CO2 emissions originating from coal, oil, and gas sectors. Its implementation was seen necessary to address the detrimental effects of CO2 on the atmosphere and the ecosystem. This recognition was achieved by previous substantial study efforts. The carbon capture and storage (CCS) cycle concludes with the final stage of CO2 storage. This stage involves primarily the adsorption of CO2 in the ocean and the injection of CO2 into subsurface reservoir formations. Additionally, the process of CO2 reactivity with minerals in the reservoir formations leads to the formation of limestone through injectivities. Carbon capture and storage (CCS) is the final phase in the CCS cycle, mostly achieved by the use of marine and underground geological sequestration methods, along with mineral carbonation techniques. The introduction of supercritical CO2 into geological formations has the potential to alter the prevailing physical and chemical characteristics of the subsurface environment. This process can lead to modifications in the pore fluid pressure, temperature conditions, chemical reactivity, and stress distribution within the reservoir rock. The objective of this study is to enhance our existing understanding of CO2 injection and storage systems, with a specific focus on CO2 storage techniques and the associated issues faced during their implementation. Additionally, this research examines strategies for mitigating important uncertainties in carbon capture and storage (CCS) practises. Carbon capture and storage (CCS) facilities can be considered as integrated systems. However, in scientific research, these storage systems are often divided based on the physical and spatial scales relevant to the investigations. Utilising the chosen system as a boundary condition is a highly effective method for segregating the physics in a diverse range of physical applications. Regrettably, the used separation technique fails to effectively depict the behaviour of the broader significant system in the context of water and gas movement within porous media. The limited efficacy of the technique in capturing the behaviour of the broader relevant system can be attributed to the intricate nature of geological subsurface systems. As a result, various carbon capture and storage (CCS) technologies have emerged, each with distinct applications, associated prices, and social and environmental implications. The results of this study have the potential to enhance comprehension regarding the selection of an appropriate carbon capture and storage (CCS) application method. Moreover, these findings can contribute to the optimisation of greenhouse gas emissions and their associated environmental consequences. By promoting process sustainability, this research can address critical challenges related to global climate change, which are currently of utmost importance to humanity. Despite the significant advancements in this technology over the past decade, various concerns and ambiguities have been highlighted. Considerable emphasis was placed on the fundamental discoveries made in practical programmes related to the storage of CO2 thus far. The study has provided evidence that despite the extensive research and implementation of several CCS technologies thus far, the process of selecting an appropriate and widely accepted CCS technology remains challenging due to considerations related to its technological feasibility, economic viability, and societal and environmental acceptance.

Yes / Capturing and storing CO2 (CCS) was once regarded as a significant, urgent, and necessary option for reducing the emissions of CO2 from coal and oil and gas industries and mitigating the serious impacts of CO2 on the atmosphere and the environment. This recognition came about as a result of extensive research conducted in the past. The CCS cycle comes to a close with the last phase of CO2 storage, which is accomplished primarily by the adsorption of CO2 in the ocean and injection of CO2 subsurface reservoir formation, in addition to the formation of limestone via the process of CO2 reactivity with reservoir formation minerals through injectivities. CCS is the last stage in the carbon capture and storage (CCS) cycle and is accomplished chiefly via oceanic and subterranean geological sequestration, as well as mineral carbonation. The injection of supercritical CO2 into geological formations disrupts the sub-surface’s existing physical and chemical conditions; changes can occur in the pore fluid pressure, temperature state, chemical reactivity, and stress distribution of the reservoir rock. This paper aims at advancing our current knowledge in CO2 injection and storage systems, particularly CO2 storage methods and the challenges encountered during the implementation of each method and analyses on how key uncertainties in CCS can be reduced. CCS sites are essentially unified systems; yet, given the scientific context, these storage systems are typically split during scientific investigations based on the physics and spatial scales involved. Separating the physics by using the chosen system as a boundary condition is a strategy that works effectively for a wide variety of physical applications. Unfortunately, the separation technique does not accurately capture the behaviour of the larger important system in the case of water and gas flow in porous media. This is due to the complexity of geological subsurface systems, which prevents the approach from being able to effectively capture the behaviour of the larger relevant system. This consequently gives rise to different CCS technology with different applications, costs and social and environmental impacts. The findings of this study can help improve the ability to select a suitable CCS application method and can further improve the efficiency of greenhouse gas emissions and their environmental impact, promoting the process sustainability and helping to tackle some of the most important issues that human being is currently accounting global climate change. Though this technology has already had large-scale development for the last decade, some issues and uncertainties are identified. Special attention was focused on the basic findings achieved in CO2 storage operational projects to date. The study has demonstrated that though a number of CCS technologies have been researched and implemented to date, choosing a suitable and acceptable CCS technology is still daunting in terms of its technological application, cost effectiveness and socio-environmental acceptance.

In image processing, it has become common the retrieval based on its own content, namely Content-Based Image Retrieval (CBIR), which eliminates the need to place additional annotations as textual descriptions and keywords registered by an observer. The purpose of this work is the development of an image retrieval mechanism based on shape recognition. The mechanism consists in (1) compute the Full Curvature Scale Space (FullCSS) image descriptors; and (2) apply over them a lossless compression method objecting to (3) classify these descriptors and retrieve the corresponding images. The FullCSS descriptors register the curvature variations on the image contour indicating the degree and the signal of these variations, which allow identifying where the curvature is concave or convex. The adopted compression method uses the Prediction by Partial Matching (PPM) compression model, which has been successfully used in other works to classify texture images. The results obtained show that this novel approach is able to reach competitive levels of efficacy and efficiency when compared to other works recently developed in this same area. / Com o aumento do poder de processamento dos computadores, cresceu também a quantidade e complexidade dos dados armazenados, exigindo mecanismos cada vez mais sofisticados para se conseguir uma recuperação eficaz e eficiente destas informações. No caso do processamento de imagens, tem se tornado comum a recuperação baseada em seu próprio conteúdo, ou seja, Recuperação de Imagem Baseada em Conteúdo (Content-Based Image Retrieval CBIR), eliminando a necessidade de anotações adicionais como descrições textuais e palavras-chave registradas por um observador. A proposta deste trabalho é o desenvolvimento de um mecanismo de recuperação de imagens através do reconhecimento de sua forma. O mecanismo consiste em (1) calcular os descritores Full Curvature Scale Space (FullCSS) das imagens; e (2) aplicar sobre eles um método de compressão sem perdas com a finalidade de (3) classificar esses descritores e recuperar as imagens correspondentes. Os descritores FullCSS registram as variações na curvatura do contorno da imagem indicando o grau e o sinal dessas variações, permitindo identificar onde a curvatura é côncava ou convexa. O método de compressão adotado utiliza o modelo de compressão Prediction by Partial Matching (PPM), utilizado com sucesso em outros trabalhos para classificar imagens de texturas. Os resultados obtidos indicam que esta abordagem inovadora é capaz de atingir níveis competitivos de eficácia e eficiência quando comparada a outros trabalhos atualmente desenvolvidos nesta mesma área.

Die fünf CSS-Domänen Phosphodiesterasen aus Escherichia coli K12 (E. coli) gehören zu den weit verbreiteten c-di-GMP-PDEs. Ein Vertreter, PdeC, wurde bereits von Herbst et al. (2018) charakterisiert. Durch DsbA/DsbB geförderte Disulfidbrückenbindung (DSB) in der CSS-Domäne von PdeC wird die PDE-Aktivität des Proteins gehemmt. Gegenteilig ist die freie Thiolform, in Abhängigkeit von der TM2 als Dimerisierungs-Domäne, enzymatisch aktiver. Diese Form wird von den periplasmatischen Proteasen DegP und DegQ prozessiert. Ein irreversibel aktiviertes TM2+EAL-Fragment wird generiert, dass durch weitere Proteolyse langsam entfernt wird. Die Reduktion der CSS-Domäne von PdeC zur der freien Thiolform stimuliert die PDE-Aktivität der EAL-Domäne in vitro. Zusammen mit den Daten von Herbst et al. (2018) wird die CSS-Domäne in dieser Arbeit als eine neue sensorische Domäne charakterisiert, dessen Aktivität durch einen DSB/Thiol-Schaltmechanismus reguliert wird. Alle fünf CSS-Domänen-PDEs von E. coli K12 weisen eine ähnliche Domänenarchitektur auf, jedoch unterscheiden sich Redox-Biochemie, Proteolyse und PDE-Aktivität innerhalb dieser Proteinfamilie. Auf Basis der PDE-Aktivität von Nicht-DSB-Varianten wurden PdeB, PdeC und PdeG als aktivierbare (Reduktion steigert die PDE-Aktivität) und PdeD und PdeN als nicht aktivierbare (Reduktion inaktiviert PDEs) charakterisiert. Ein weiterer Vertreter de CSS-Domänen PDEs, PdeN, scheint nicht über die Ausbildung einer DSB in der CSS-Domäne reguliert und aktiviert zu werden. Nach erfolgter Proteinbiosynthese wird die Proteinkonzentration vielmehr über den N-Terminus reguliert, wobei saure Wachstumsbedingungen das Protein maßgeblich induzieren und die Aktivität erhöhen. Wird das Protein erfolgreich in die Membran eingelagert, kann es bedingt durch die strukturelle DSB seine PDE-Aktivität entfalten und die Biofilmmatrixproduktion maßgeblich beeinflussen. / The five CSS domain phosphodiesterases from Escherichia coli K12 (E. coli) belong to the widespread group of c-di-GMP PDEs. One representative, PdeC, has already been characterized by Herbst et al. (2018). DsbA/DsbB promoted disulfide bond (DSB) formation in the CSS domain of PdeC inhibits the PDE activity of the protein. On the contrary, the free thiol form is more enzymatically active, depending on the TM2 as the dimerization domain. This form is processed by the periplasmic proteases DegP and DegQ. An irreversibly activated TM2 + EAL fragment is generated that is slowly removed by further proteolysis. The reduction of the CSS domain of PdeC to the free thiol form stimulates the PDE activity of the EAL domain in vitro. Together with the data from Herbst et al. (2018) the CSS domain is characterized as a new sensory domain whose activity is regulated by a DSB / thiol switch mechanism. All five E. coli K12 CSS domain PDEs share a similar domain architecture, but redox biochemistry, proteolysis, and PDE activity differ within the protein family. On the basis of the PDE activity of non-DSB variants, PdeB, PdeC and PdeG were characterized as activatable (reduction increases PDE activity) and PdeD and PdeN as non-activatable (reduction inactivated PDE activity). Another representative of the CSS domain PDEs, PdeN, does not seem to be regulated and activated by forming a DSB in the CSS domain. After protein biosynthesis the protein concentration is rather regulated via the N-terminus, with acidic growth conditions significantly inducing the protein and increasing its activity. If the protein is successfully inserted in the membrane, it can develop its PDE activity due to the structural DSB and influence the biofilm matrix production significantly.
