Abstract:
The main objective of this study is to develop a novel dual-purpose material based on carbon xerogel microspheres (CXMs) that permits the delayed release of cannabidiol (CBD) and the removal of aflatoxin. The CXMs were prepared by the sol-gel method and functionalized with phosphoric acid (CXMP) and melamine (CXMN). The support and the modified materials were characterized by scanning electronic microscopy (SEM), N2 adsorption at −196 °C, X-ray photoelectron spectroscopy (XPS), and zeta potential. For the loading of the cannabidiol (CBD) in the porous samples, batch–mode adsorption experiments at 25 °C were performed, varying the concentration of CBD. The desorption kinetics was performed at two conditions for simulating the gastric (pH of 2.1) and intestinal (pH of 7.4) conditions at 37 °C based on in vitro CBD release. Posteriorly, the samples obtained after desorption were used to study aflatoxin removal, which was evaluated through adsorption experiments at pH = 7.4 and 37 °C. The adsorption isotherms of CBD showed a type I(b) behavior, with the adsorbed uptake being higher for the support than for the modified materials with P and N. Meanwhile, the desorption kinetics of CBD at gastric conditions indicated release values lower than 8%, and the remaining amount was desorbed at pH = 7.4 in three hours until reaching 100% based on the in vitro experiments. The results for aflatoxin showed total removal in less than 30 min for all the materials evaluated. This study opens a broader landscape in which to develop dual-purpose materials for the delayed release of CBD, improving its bioavailability and allowing aflatoxin removal in gastric conditions.

Abstract:
Low-alloy 42CrMo4 steels were studied by 57Fe Mössbauer spectroscopy (MS), X-ray diffractometry (XRD), and Energy Dispersive X-ray Spectroscopy (EDS) measurements. The investigations were performed on metallographic samples, which were subjected to a series of successive grinding and polishing with a progressively finer grit. Conversion X-ray Mössbauer spectroscopy (CXMS) was used to determine the occurrence of austenite in steel samples. It is a unique method detecting the austenite content very sensitively. Six samples with different surface preparation were investigated, starting with 4.8% of austenite on an as-cut sample, and a large decrease in the retained austenite to 2.6% was observed after the first grinding of a hardened cut sample. Additionally, an unexpectedly large decrease in the austenite content to 2.3% was found due to the final polishing. A second time applied successive grinding and polishing of all samples resulted in identical austenite content determined by CXMS of approx. 5%, which proved the applicability of the CXMS method. Generally, the result calls attention to the importance of preparation of metallurgical samples by grinding and polishing where the results can vary significantly on the level of surface processing.

Abstract:
Chemical cross-linking mass spectrometry (CXMS) is being increasingly used to study protein assemblies and complex protein interaction networks. Existing CXMS chemical cross-linkers target only Lys, Cys, Glu, and Asp residues, limiting the information measurable. Here we report a “plant-and-cast” cross-linking strategy that employs a heterobifunctional cross-linker that contains a highly reactive succinimide ester as well as a less reactive sulfonyl fluoride. The succinimide ester reacts rapidly with surface Lys residues “planting” the reagent at fixed locations on protein. The pendant aryl sulfonyl fluoride is then “cast” across a limited range of the protein surface, where it can react with multiple weakly nucleophilic amino acid sidechains in a proximity-enhanced sulfur-fluoride exchange (SuFEx) reaction. Using proteins of known structures, we demonstrated that the heterobifunctional agent formed cross-links between Lys residues and His, Ser, Thr, Tyr, and Lys sidechains. This geometric specificity contrasts with current bis-succinimide esters, which often generate nonspecific cross-links between lysines brought into proximity by rare thermal fluctuations. Thus, the current method can provide diverse and robust distance restraints to guide integrative modeling. This work provides a chemical cross-linker targeting unactivated Ser, Thr, His, and Tyr residues using sulfonyl fluorides. In addition, this methodology yielded a variety of cross-links when applied to the complex Escherichia coli cell lysate. Finally, in combination with genetically encoded chemical cross-linking, cross-linking using this reagent markedly increased the identification of weak and transient enzyme–substrate interactions in live cells. Proximity-dependent cross-linking will dramatically expand the scope and power of CXMS for defining the identities and structures of protein complexes.

Abstract:
Aiming to elucidate the system-wide effects of the alcohol-induced increase in the content of cytochrome P450 2E1 (CYP2E1) on drug metabolism, we explored the array of its protein-protein interactions (interactome) in human liver microsomes (HLM) with chemical crosslinking mass spectrometry (CXMS). Our strategy employs membrane incorporation of purified CYP2E1 modified with photoreactive crosslinkers benzophenone-4-maleimide and 4-(N-succinimidylcarboxy)benzophenone. Exposure of bait-incorporated HLM samples to light was followed by isolating the His-tagged bait protein and its crosslinked aggregates on Ni-NTA agarose. Analyzing the individual bands of SDS-PAGE slabs of thereby isolated protein with the toolset of untargeted proteomics, we detected the crosslinked dimeric and trimeric complexes of CYP2E1 with other drug-metabolizing enzymes. Among the most extensively crosslinked partners of CYP2E1 are the cytochromes P450 2A6, 2C8, 3A4, 4A11, and 4F2, UDP-glucuronosyltransferases (UGTs) 1A and 2B, fatty aldehyde dehydrogenase (ALDH3A2), epoxide hydrolase 1 (EPHX1), disulfide oxidase 1α (ERO1L), and ribophorin II (RPN2). These results demonstrate the exploratory power of the proposed CXMS strategy and corroborate the concept of tight functional integration in the human drug-metabolizing ensemble through protein-protein interactions of the constituting enzymes.

Abstract:
Selective laser melting (SLM) is a technology of layer-by-layer additive manufacturing using a laser. This technology allows one to get complex-shaped, three-dimensional (3D) specimens directly from metal powder. In this technology, various metal powders are used, including different steels. Stainless steel 1.4404 (CL20ES) and maraging steel 1.2709 (CL50WS) have been investigated. The surface of samples manufactured from CL20ES and CL50WS powders by SLM (with and without combination sandblasting and annealing) was studied by conversion X-ray Mössbauer spectroscopy (CXMS) and conversion electron Mössbauer spectroscopy (CEMS). The surface morphology, elemental composition, and structure were examined by scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS), and X-ray powder diffraction (XRD). Samples with sandblasted (corundum powder) and non-sandblasted surfaces were annealed at 540 °C (CL50WS) or 550 °C (CL20ES) for 6 h in air. Oxidation processes on surfaces of samples manufactured from both initial powders were observed after post-process annealing by CEMS and CXMS, as well as confirmed by XRD. The transformation of the austenitic to ferritic phase was observed in a sandblasted and annealed CL20ES sample by CEMS and XRD.

Abstract:
Selective laser melting (SLM) as an additive manufacturing method makes it possible to quickly produce complexly shaped three-dimensional (3D) metal specimens from a powder. This work describes how SLM affects the surface phase composition of a 3D printed specimen, as analyzed with conversion electron Mössbauer spectroscopy (CEMS), conversion X-ray Mössbauer spectroscopy (CXMS) and X-ray diffraction (XRD). Both stainless 1.4404 (CL20ES) steel and maraging 1.2709 (CL50WS) steel have been investigated. A transformation of the phase composition from the ferritic phase into an austenitic one was proven by comparing the initial CL50WS powder and the final specimen using CXMS. This transformation takes place during the SLM process. No transformation was identified in stainless steel. The differences identified via CEMS between the surface phase composition of the final non-annealed specimens and the surface of the final annealed specimens demonstrated the oxidation of the surface layer. The oxidation occurs during the annealing of the sample in surface layers less than 1 μm thick. The quality of the surface was examined using scanning electron microscopy (SEM), which presented imperfections on the face of the final specimen. Granules of the initial powder bonded to the surface of the specimen and both irregular and spherical pores were observed.

Abstract:
Context-based Reasoning (CxBR) and Contextual Graphs (CxGs) involve the modeling of human behavior in autonomous and decision-support situations in which optimal human decision-making is of utmost importance. Both formalisms use the notion of contexts to allow the implementation of intelligent agents equipped with a context sensitive knowledge base. However, CxBR uses a set of discrete contexts, implying that models created using CxBR operate within one context at a given time interval. CxGs use a continuous context-based representation for a given problem-solving scenario for decision-support processes. Both formalisms use contexts dynamically by continuously changing between necessary contexts as needed in appropriate instances. This thesis identifies a synergy between these two formalisms by looking into their similarities and differences. It became clear during the research that each paradigm was designed with a very specific family of problems in mind. Thus, CXBR best implements models of autonomous agents in environment, while CxGs is best implemented in a decision support setting that requires the development of decision-making procedures. Cross applications were implemented on each and the results are discussed.

Abstract:

It is not easy to apply XML in e-commerce development for achieving interoperability in heterogeneous environments. One of the reasons is a multitude of XML-based Frameworks for Internet Commerce (XFIC), or industrial standards. This thesis surveys 15 frameworks, i.e., ebXML, eCo Framework, UDDI, SOAP, BizTalk, cXML, ICE, Open Applications Group, RosettaNet, Wf-XML, OFX, VoiceXML, RDF, WSDL and xCBL.

This thesis provides three models to systematically understand how the 15 frameworks meet the requirements of e-commerce. A hierarchical model is presented to show the purpose and focus of various XFIC initiatives. A relationship model is given to show the cooperative and competitive relationships between XFIC. A chronological model is provided to look at the development of XFIC. In addition, the thesis offers guidelines for how to apply XFIC in an e-commerce development.

We have also implemented a B2B e-procurement system. That not only demonstrates the feasibility of opensource or freeware, but also validates the complementary roles of XML and Java: XML is for describing contents and Java is for automating XML documents (session handling). Auction-based dynamic pricing is also realized as a feature of interest. Moreover, the implementation shows the suitability of e-procurement for educational purposes in e-commerce development.

Abstract:
The study of protein structure and interactions is pivotal in understanding the function and malfunction of complex biological systems. The structures of some proteins are unable to be determined using traditional high resolution biophysical techniques, requiring the development of amenable low resolution alternatives. Chemical Crosslinking Mass Spectrometry (CXMS) is one technique which can be used to probe protein structure through the formation of covalent linkages between protein residues. The formation of these links is facilitated by chemical crosslinking reagents. Widespread use of the CXMS technique has been hampered primarily by analytical challenges pertaining to the detection and identification of crosslinked species using Mass Spectrometry (MS). Attempts to mitigate the challenges have been made by modifying the structure of chemical crosslinkers through the addition of functional groups such as affinity tags, isotope labels and cleavable bonds. Crosslinkers combining more than one type of functional group (combination crosslinkers) present the most promising targets for CXMS applications, combining the benefits of each functional group. However, combination crosslinkers are not commercially available, thus necessitating in-house synthesis. Incorporating more than one functionality also results in more complex molecular structures and synthetic processes, making the crosslinkers difficult to adapt to suit a particular experiment. Consequently, the use of combination crosslinkers has been limited to date to a small number of studies. The research presented in this thesis describes the development of a modular chemical crosslinker design and corresponding synthetic protocol for the synthesis of combination crosslinkers. The modular crosslinker structure can be readily modified to include a range of functional groups using a small number of different reactions, including amide coupling and O-alkylation, and commercially available starting materials such as Boc-serine, from a minimum of five synthetic steps. The utility of the synthetic process was validated through the synthesis of a crosslinker containing an alkyne functional group, which can be used to attach a biotin affinity tag through alkyne-azide Huisgen Cyclisation. Synthesis of two custom designed combination crosslinkers utilising alkyne tags and cleavable bonds is also described. The function of the cleavable bonds was established using collision induced dissociation processes within the mass spectrometer. Ensuring that a crosslinker is effective in probing quaternary structure and protein- protein interactions is essential as the investigation of these structures is a major goal of CXMS. Therefore, a crosslinking assay using Staphylococcus aureus biotin protein ligase, which forms homodimers when substrate bound, was also developed using the commercially available crosslinkers Disuccinimidyl Suberate (DSS) and Dithiobis(succinimidyl) Propionate (DSP), to enable the efficacy of crosslinkers synthesised using the modular synthetic protocol to be determined.

Abstract:
The Wide-View Charge Exchange Recombination Spectroscopy (CXRS) diagnostic at Alcator C-Mod, originally designed for measurement of boron, has been modified to fit several different roles. By measuring the He¹⁺ (n = 4 [rightwards arrow] 3) emission line at 4686Å and surrounding spectra, we can measure ⁴He and ³He density, temperature, and velocity profiles and use this information to study turbulent impurity transport. The transport is characterized using a standard ansatz for the radial particle flux: [mathematical equation]. This effort is designated He CXRS. Also, direct measurement of ³He are used to test models of Ion Cyclotron Resonance Heating (ICRH). We look for evidence of fast ion production and the effect of the minority ion profile on fast wave heating. Several modifications were made to the hardware. Light is collected via two optical arrays: poloidal and toroidal. The toroidal array has been upgraded to increase throughput and spatial resolution, increasing the number of toroidal channels from 10 to 22. A new protective shroud was installed on the poloidal array. Additional diagnostics (a 11 channel beam duct view, neutralizer view, duct pressure monitor) were added to the Diagnostic Neutral Beam to improve DNB modeling for CXRS. This work includes investigation of plasmas where helium is at low concentration (<1%), acting passively, as well as scenarios with a large fraction (>~20%). Using the STRAHL code, time-dependent helium density profiles are used to obtain anomalous transport parameters. Thermodiffusion and curvature pinch terms are also estimated from experimental scaling studies. Results are compared with neoclassical results from the NCLASS code and calculations by the GENE gyrokinetic code. Another focus is verification of power deposition models which are crucially dependent on minority ion density, for which ³He is used. At low ³He fraction, direct absorption by ³He generates fast ions with anisotropic velocity-space distribution functions. At high ³He fraction, mode conversion heating of electrons is dominant. The minority distribution function and predicted wave deposition are simulated using AORSA and CQL3D. This work provides the first measurements of helium transport on C-Mod and expands our understanding of helium transport and fast wave heating.

Dissertação de mestrado em Engenharia de Sistemas
Since its creation, one of the European Union big premises is creating the proper conditions for their member states unification on several levels. Therefore, efforts have been carried out to unify the European Union into a single market. On the actual economic context, it is undeniable the information technology impact upon the way company conduct business, especially regarding buying and selling of goods and services. Thus, Vortal (Portuguese market leader on electronic procurement and having strong intentions to expand internationally, with its Vortal Next> platform), is closely following the strategic changes occurring within the European Union, regarding electronic procurement. A big change will happen by 2016, where all public procurement procedures will have to be carried out electronically by then. Under the referred measure, it is expectable for procurement platforms to be created, or at least, more users joining the existing ones. Having then more users on the market, it can be seen as a business opportunity, if there is a way to overcome the existing interoperability problems between procurement platforms. That would allow the users residing in a certain platform to be able to conduct business with users residing in other platforms on a transparent fashion. Having the need for a solution that solves the interoperability problem between procurement platforms, three E-Procurement Open Standards are analyzed and compared: cXML, XVergabe and PEPPOL. It is presented then the architecture of an integration solution, called Driving E-Procurement, where an Open Standard is used in order to attain interoperability between Vortal Next> platform and every platform using cXML. However, the solution is thought and design for the future possibility of integration with platforms using other Open Standards such as XVergabe or PEPPOL. With this kind of solution, it would be possible to bring the market entities together in a transparent, flexible and effective fashion.
Desde a sua criação, uma das grandes premissas da União Europeia é criar condições para a unificação, a vários níveis, dos seus estados membros. Consequentemente, muitos esforços têm sido feitos no sentido de unificar a União Europeia a nível do comércio. No actual contexto económico, ninguém poderá negar o impacto das tecnologias de informação na forma como as empresas conduzem negócios hoje em dia, nomeadamente na compra e venda de bens e serviços. Assim sendo, a Vortal está atenta às mudanças estratégicas, no contexto da contratação electrónica, na União Europeia. Uma grande mudança acontecerá em 2016, onde todos os procedimentos públicos de contratação, terão de ser feitos obrigatoriamente de forma electrónica. No âmbito da referida medida, é expectável que surjam no contexto da União Europeia mais plataformas de contratação electrónica, ou pelo menos, mais utilizadores a aderirem às plataformas existentes no mercado. Havendo mais entidades no mercado, esta situação poderá apresentar-se como uma oportunidade de negocio, se houver maneira de ultrapassar os problemas de interoperabilidade entre as plataformas e as entidades presentes numa determinada plataforma serem capazes de conduzir negócios com entidades noutras plataformas, apenas estando, cada entidade, registada numa plataforma. Havendo a necessidade de uma solução que permita resolver o problema de falta de interoperabilidade entre plataformas de contratação electrónica, são estudados e comparados três Open Standards de contratação electrónica: cXML, Xvergabe e PEPPOL. É apresentada uma solução onde um Open Stardard é peça fundamental para resolver o referido problema de interoperabilidade. Por fim, é apresentada a arquitectura de uma solução de integração, chamada Driving E-Procurement, onde é utilizado o Open Stardard de forma a atingir interoperabilidade entre a Vortal Next> e todas as plataformas que usem o cXML. Contudo, a solução está pensada e desenhada para que no futuro seja possível atingir interoperabilidade com plataformas que usem outros Open Standards, como o Xvergabe ou o PEPOOL. Desta forma, será possível aproximar as entidades no mercado duma forma transparente, flexível e eficaz para essas mesmas entidades.

Abstract:
Most lung nodules missed by radiologists as well as Computer-Aided Diagnostic (CADe) schemes overlap ribs or clavicles in Chest Radiographs (CXRs). This chapter introduces an image-processing technique for suppressing the contrast of ribs and clavicles in CXRs by means of anatomically specific Multiple Massive-Training Artificial Neural Networks (MTANNs). For bone suppression, an MTANN is trained by use of input CXRs and the corresponding “teaching” images. The authors employed bone images obtained by the use of a dual-energy subtraction technique as the teaching images. For the effective suppression of ribs, having various spatial frequencies, the authors developed a multi-resolution MTANN consisting of multi-resolution decomposition/composition techniques and three MTANNs for three different-resolution images. After training with input CXRs and the corresponding dual-energy bone images, the multi-resolution MTANN was able to provide “bone-image-like” images which were similar to the teaching bone images. By subtracting the “bone-image-like” images from the corresponding CXRs, the authors were able to produce “soft-tissue-image-like” images in which ribs and clavicles were substantially suppressed. A single set of multi-resolution MTANNs cannot suppress all bone structures in a CXR, because the orientation, width, contrast, and density of bones differ from location to location, and the capability of a single set of multi-resolution MTANNs is limited. To address this issue, the authors developed anatomically specific multiple MTANNs which consist of eight sets of multi-resolution MTANNs that were designed to process different segments in the lung fields in a CXR. Each set of anatomically specific MTANNs was trained with only the samples in the corresponding segment in the CXR. In order to make the contrast and density between the segments consistent, the authors applied a histogram matching technique to input images. To improve the performance of their CADe scheme, the authors incorporated their MTANN bone suppression into their CADe scheme for nodules in CXRs. In their CADe scheme, 64 morphologic and gray-level-based features were extracted from each nodule candidate in both the original and the “soft-tissue-image-like images,” and a nonlinear support vector classifier was employed for the classification of the candidates. The authors used a validation test database consisting of 118 CXRs with pulmonary nodules and a publicly available database containing 126 nodules. When their technique was applied to non-training CXRs, bones in the CXRs were suppressed substantially, while the visibility of nodules and lung vessels was maintained. With the use of “soft-tissue-image-like images,” the performance of the authors’ CADe scheme was improved from a sensitivity of 76% to 84% with 5 false positives per image. Thus, the authors’ image-processing technique for bone suppression by means of anatomically specific multiple MTANNs is useful for radiologists as well as for CAD schemes in the detection of lung nodules on CXRs.

Abstract:
This chapter delves into interactions among CXOs in terms of their involvement in and contributions to the senior leadership team. It focuses on how CXOs work with one another and with the CEO as members of the top team. To explore these collective dynamics, the chapter first reviews the structure, composition, and processes of top management teams, as well as their main benefits and challenges. The discussion then turns to competing, and collaborating in the C-suite, thereby revealing tensions and balancing acts. The concluding section highlights some implications for the model and operations of the C-suite as a top team oriented to enabling organizational agility and expanding the organization’s future horizons.
