Abstract:
Adenylyl cyclases (ACs) convert ATP into the classical second messenger cyclic adenosine monophosphate (cAMP). Cardiac ACs, specifically AC5, AC6, and AC9, regulate cAMP signaling controlling functional outcomes such as heart rate, contractility and relaxation, gene regulation, stress responses, and glucose and lipid metabolism. With so many distinct functional outcomes for a single second messenger, the cell creates local domains of cAMP signaling to correctly relay signals. Targeting of ACs to A-kinase anchoring proteins (AKAPs) not only localizes ACs, but also places them within signaling nanodomains, where cAMP levels and effects can be highly regulated. Here we will discuss the recent work on the structure, regulation and physiological functions of AC9 in the heart, where it accounts for <3% of total AC activity. Despite the small contribution of AC9 to total cardiac cAMP production, AC9 binds and regulates local PKA phosphorylation of Yotiao-IKs and Hsp20, demonstrating a role for nanometric targeting of AC9.

Abstract:
Pineapple is a perennial fruit-bearing tropical plant that belongs to the Bromeliaceae family, which has more than 2500 species. Pineapple is known excellent source of minerals and vitamins. It produces substantial calcium, potassium, glucose, the proteindigesting enzyme bromelain, fibre, vitamin A, B and C. In Malaysia, twelve registered varieties of pineapple have been introduced and commercially planted such as Moris (AC1), Sarawak (AC2), Gandul (AC3), Maspine (AC4), Josapine (AC5) Yankee (AC6) Moris Gajah (AC7), N36 (AC8), MD2 (AC9), View of Sunset (AC10), Madu Kaca (AC11), and Keningau Diamond (AC12). The disease is one of the important factors that can contribute to the huge losses of pineapple yield worldwide. This review paper aimed to discuss the main diseases of pineapple and their control management, particularly in Malaysia. The common diseases of pineapple that cause significant yield losses in the farms such as mealybug wilt-associated virus, bacterial heart rot, fruit collapse, butt rot, fruitlet core rot, black rot, yeasty and fusariosis are highlighted and discussed in detail on the causal pathogens, disease symptoms and signs, disease infection and development. The available control measures for managing pineapple diseases were also included in this paper.

Abstract:
Purslane (Portulaca oleraceaL.) is an herbaceous leafy vegetable crop, comparatively more salt-tolerant than any other vegetables with high antioxidants, minerals, and vitamins. Salt-tolerant crop variety development is of importance due to inadequate cultivable land and escalating salinity together with population pressure. In this view a total of 25 purslane accessions were initially selected from 45 collected purslane accessions based on better growth performance and subjected to 5 different salinity levels, that is, 0.0, 10.0, 20.0, 30.0, and 40.0 dS m−1NaCl. Plant height, number of leaves, number of flowers, and dry matter contents in salt treated purslane accessions were significantly reduced (P≤0.05) and the enormity of reduction increased with increasing salinity stress. Based on dry matter yield reduction, among all 25 purslane accessions 2 accessions were graded as tolerant (Ac7 and Ac9), 6 accessions were moderately tolerant (Ac3, Ac5, Ac6, Ac10, Ac11, and Ac12), 5 accessions were moderately susceptible (Ac1, Ac2, Ac4, Ac8, and Ac13), and the remaining 12 accessions were susceptible to salinity stress and discarded from further study. The selected 13 purslane accessions could assist in the identification of superior genes for salt tolerance in purslane for improving its productivity and sustainable agricultural production.

Abstract:
Activation of adenylyl cyclase (AC), of which there are 10 diversely regulated isoforms, is important in regulating pulmonary vascular tone and remodeling. Immunohistochemistry in rat lungs demonstrated that AC2, AC3, and AC5/6 predominated in vascular and bronchial smooth muscle. Isoforms 1, 4, 7, and 8 localized to the bronchial epithelium. Exposure of animals to hypoxia did not change the pattern of isoform expression. RT-PCR confirmed mRNA expression of AC2, AC3, AC5, and AC6 and demonstrated AC7 and AC8 transcripts in smooth muscle. Western blotting confirmed the presence of AC2, AC3, and AC5/6 proteins. Functional studies provided evidence of cAMP regulation by Ca2+ and protein kinase C-activated but not Gi-inhibited pathways, supporting a role for AC2 and a Ca2+-stimulated isoform, AC8. However, NKH-477, an AC5-selective activator, was more potent than forskolin in elevating cAMP and inhibiting serum-stimulated [3H]thymidine incorporation, supporting the presence of AC5. These studies demonstrate differential expression of AC isoforms in rat lungs and provide evidence that AC2, AC5, and AC8 are functionally important in cAMP regulation and growth pathways in pulmonary artery myocytes.

Abstract:
Intracellular and secreted cAMPs play crucial roles in controlling cell movement and gene regulation throughout development of the social amoeba Dictyostelium discoideum. cAMP is produced by three structurally distinct ACs (adenylate cyclases), ACA, ACG and ACB, which have distinctive but overlapping patterns of expression and, as concluded from gene disruption studies, seemingly overlapping functions. In addition to gene disruption, acute pharmacological abrogation of protein activity can be a powerful tool to identify the protein's role in the biology of the organism. We analysed the effects of a range of compounds on the activity of ACA, ACB and ACG to identify enzyme-specific modulators. Caffeine, which was previously used to specifically block ACA function, also inhibited cAMP accumulation by ACB and ACG. IPA (2′,3′-O-isopropylidene adenosine) specifically inhibits ACA when measured in intact cells, without affecting ACB or ACG. All three enzymes are inhibited by the P-site inhibitor DDA (2′,5′-dideoxyadenosine) when assayed in cell lysates, but not in intact cells. Tyrphostin A25 [α-cyano-(3,4,5-trihydroxy)cinnamonitrile] and SQ22536 [9-(tetrahydro-2′-furyl)adenine] proved to be effective and specific inhibitors for ACG and ACA respectively. Both compounds acted directly on enzyme activity assayed in cell lysates, but only SQ22536 was also a specific inhibitor when added to intact cells.

Abstract:
Metabolic syndrome (MetS) is a group of several metabolic conditions predisposing to chronic diseases. Individuals diagnosed with MetS are physiologically heterogeneous, with significant sex-specific differences. Therefore, we aimed to investigate the potential sex-specific serum modifications of amino acids and acylcarnitines (ACs) and their relationship with MetS in the Mexican population. This study included 602 participants from the Health Workers Cohort Study. Forty serum metabolites were analyzed using a targeted metabolomics approach. Multivariate regression models were used to test associations of clinical and biochemical parameters with metabolomic profiles. Our findings showed a serum amino acid signature (citrulline and glycine) and medium-chain ACs (AC14:1, AC10, and AC18:10H) associated with MetS. Glycine and AC10 were specific metabolites representative of discrimination according to sex-dependent MetS. In addition, we found that glycine and short-chain ACs (AC2, AC3, and AC8:1) are associated with age-dependent MetS. We also reported a significant correlation between body fat and metabolites associated with sex-age-dependent MetS. In conclusion, the metabolic profile varies by MetS status, and these differences are sex-age-dependent in the Mexican population.

Abstract:
Little is known about collecting duct adenylyl cyclase (AC) isoforms or regulation in the mouse. We performed RT-PCR for AC isoforms 1–9 in microdissected cortical (CCD) and outer medullary (OMCD) and acutely isolated inner medullary (IMCD) collecting duct. All collecting duct regions contained AC3, AC4, and AC6 mRNA, while CCD and OMCD, but not IMCD, also contained AC5 mRNA. Acutely isolated IMCD expressed AC3, AC4, and AC6 proteins by Western blot analysis. The mIMCD3 cell line expressed AC2, AC3, AC4, AC5, and AC6 mRNA; M-1 CCD cells expressed AC2, 3, 4, and 6, while mpkCCD cell lines contained AC3, AC4, and AC6 mRNA. AVP stimulated cAMP accumulation in acutely isolated mouse IMCD; this was reduced by chelation of extracellular calcium (EGTA) and almost completely abolished by blockade of calmodulin (W-7). Blockade of calmodulin kinase with KN-93 or endoplasmic reticulum calcium ATPase (thapsigargin) also reduced the AVP response. A similar inhibitory effect of W-7, KN-93, and thapsigargin was seen on forskolin-stimulated cAMP content in acutely isolated mouse IMCD. These three agents had the same pattern of blockade of AVP- or forskolin-stimulated AC activity in acutely isolated rat IMCD. AVP responsiveness in primary cultures of mouse IMCD was also reduced by W-7, KN-93, and thapsigargin. Small interfering RNA (siRNA) designed to knock down AC3 or AC6 in primary cultured mouse IMCD significantly reduced AVP-stimulated cAMP accumulation. Together, these data are consistent with a role of AC3 and AC6 in the activation of mouse collecting duct by AVP.

Abstract:
13 selected purslane accessions were subjected to five salinity levels 0, 8, 16, 24, and 32 dS m−1. Salinity effect was evaluated on the basis of biomass yield reduction, physiological attributes, and stem-root anatomical changes. Aggravated salinity stress caused significant (P<0.05) reduction in all measured parameters and the highest salinity showed more detrimental effect compared to control as well as lower salinity levels. The fresh and dry matter production was found to increase in Ac1, Ac9, and Ac13 from lower to higher salinity levels but others were badly affected. Considering salinity effect on purslane physiology, increase in chlorophyll content was seen in Ac2, Ac4, Ac6, and Ac8 at 16 dS m−1salinity, whereas Ac4, Ac9, and Ac12 showed increased photosynthesis at the same salinity levels compared to control. Anatomically, stem cortical tissues of Ac5, Ac9, and Ac12 were unaffected at control and 8 dS m−1salinity but root cortical tissues did not show any significant damage except a bit enlargement in Ac12 and Ac13. A dendrogram was constructed by UPGMA based on biomass yield and physiological traits where all 13 accessions were grouped into 5 clusters proving greater diversity among them. The 3-dimensional principal component analysis (PCA) has also confirmed the output of grouping from cluster analysis. Overall, salinity stressed among all 13 purslane accessions considering biomass production, physiological growth, and anatomical development Ac9 was the best salt-tolerant purslane accession and Ac13 was the most affected accession.

Abstract:
The adsorption of acetaldehyde from air using various activated carbon and carbon fibers was investigated in this study. These adsorbents included activated carbon (AC), carbon fibers (CFs), activated carbon fibers (ACFs), and metal-coated carbon fibers (MCCFs) supplied by different manufacturers. AC was categorized as AC1, AC2, AC3, and AC4, CFs were denoted as ACF1, while ACFs and MCCFs were expressed as ACF2 and ACF3, respectively. Five composite materials were prepared using the AC and ACFs in different ratios, and experiments were conducted to assess their acetaldehyde adsorption efficiency under dry and wet conditions. The results showed that the acetaldehyde adsorption efficiency of an impregnated AC4 was higher (95.9%) than that of both non-impregnated AC1 and AC3 and an impregnated AC2 after 1 min of operation. ACF2 showed a higher acetaldehyde adsorption efficiency (50.9%) as compared to ACF1 and ACF3 because of its larger surface area and selective absorption capability after 1 min of operation. A composite material comprising 6.3 g of AC4 and 1 g of ACF2 showed the highest adsorption efficiency of 97.9% under dry conditions. However, this adsorption efficiency significantly decreased under wet conditions.

Abstract:
Mammals express nine membranous adenylyl cyclase isoforms (ACs 1–9), a structurally related soluble guanylyl cyclase (sGC) and a soluble AC (sAC). Moreover,Bacillus anthracisandBacillus pertussisproduce the AC toxins, edema factor (EF), and adenylyl cyclase toxin (ACT), respectively. 2′(3′)-O-(N-methylanthraniloyl)-guanosine 5′-[γ-thio]triphosphate is a potent competitive inhibitor of AC in S49 lymphoma cell membranes. These data prompted us to study systematically the effects of 24 nucleotides on AC in S49 and Sf9 insect cell membranes, ACs 1, 2, 5, and 6, expressed in Sf9 membranes and purified catalytic subunits of membranous ACs (C1 of AC5 and C2 of AC2), sAC, sGC, EF, and ACT in the presence of MnCl2.N-Methylanthraniloyl (MANT)-GTP inhibited C1·C2 with aKiof 4.2 nm. Phe-889 and Ile-940 of C2 mediate hydrophobic interactions with the MANT group. MANT-inosine 5′-[γ-thio]triphosphate potently inhibited C1·C2 and ACs 1, 5, and 6 but exhibited only low affinity for sGC, EF, ACT, and G-proteins. Inosine 5′-[γ-thio]triphosphate and uridine 5′-[γ-thio]triphosphate were mixed G-protein activators and AC inhibitors. AC5 was up to 15-fold more sensitive to inhibitors than AC2. EF and ACT exhibited unique inhibitor profiles. At sAC, 2′,5′-dideoxyadenosine 3′-triphosphate was the most potent compound (IC50, 690 nm). Several MANT-adenine and MANT-guanine nucleotides inhibited sGC withKivalues in the 200–400 nmrange. UTP and ATP exhibited similar affinities for sGC as GTP and were mixed sGC substrates and inhibitors. The exchange of MnCl2against MgCl2reduced inhibitor potencies at ACs and sGC 1.5–250-fold, depending on the nucleotide and cyclase studied. The omission of the NTP-regenerating system from cyclase reactions strongly reduced the potencies of MANT-ADP, indicative for phosphorylation to MANT-ATP by pyruvate kinase. Collectively, AC isoforms and sGC are differentially inhibited by purine and pyrimidine nucleotides.

Abstract:
This thesis is about the construction and design of a new air bearing test-bed to verify the programmed ACS attitude control algorithm and to validate the ACS MATLAB/SimuLink¬ model of NPSAT1, the second small satellite currently under development at the Naval Postgraduate School Space Systems Academic Group. The software was already verified and validated using a comparable air bearing test-bed. But due to changes in hardware from commercial magnetic torque rods to custom, NPS-built, magnetic torque coils, the changes in the modulated software have to be verified again. Additionally, the use of flight hardware on the test-bed is expanded to also verify and validate the currently available flight hardware. NPSAT1 is a passive, gravity-gradient stabilized satellite. This thesis shows the necessary fundamental requirements on the satellite's mass properties, which has to be met to realize a gravity-gradient stabilized satellite, as well as the basics of pendulum theory, which is required to set up the test-bed on the air bearing for testing. This thesis describes the measurement of the earth's magnetic field taken in the SSAG laboratory and the resulting magnetic field vector field. Restrictions dictatd by the air bearing are followed by a chapter that summarizes and explains all requirements on the new test-bed design. A detailed description of the chosen design approach, layout and available test-bed configurations is given, as well as issues encountered and their solutions.The next step is to verify the ACS MATLAB/SimuLink¬ attitude control algorithm and to validate the MATLAB/SimuLink¬ model using the designed air bearing test-bed. Further, it is suggested to proceed the verification and validiation of NPSAT1's behavior in space by using the custom, NPS-built, Helmholtz coils. With the assistance of Helmholtz coils, custom magnetic field properties can be generated.

Abstract:
Introduction There is a pressing clinical need to treat patients with acute coronary syndrome (ACS) timely and efficiently in order to improve their prognosis. Standard tools available in ED, while useful, do not comprehensively characterize ACS for either diagnosis or risk stratification. The role of CMR in ACS is emerging because it allows assessment of both myocardial composition and function. Newer CMR techniques such as: a) T2 W imaging for assessing myocardial oedema and area at risk B) pre contrast T1 mapping techniques for quantitative characterization of the tissue composition, are adding further utility for CMR in ACS. At present the clinical use of these techniques is still limited and further investigations are needed to assess their clinical applicability in ACS patients. Aims The aims of this thesis were several. Firstly we sought to establish a CMR protocol for imaging ACS patients on a 3T CMR scanner. In order to do so, we validated a novel T2 W technique for oedema imaging (T2 prep SSFP) at 3T. Second, we aimed to perform a detailed study of the time course of oedema in ACS patients in order to establish the appropriate imaging time for the assessment of area at risk. Third, by applying T2W acute oedema imaging, we sought to investigate the functional and pathological meaning of complicated remote plaques in patients with multivessel disease. Finally, we aimed to establish whether, in comparison to standard CMR techniques, novel precontrast Tl mapping allows better characterisation of the acutely injured myocardium and whether it can predict long-term functional recovery. Methods The research studies were all performed on a 3T Trio Siemens scanner. In the initial stage of the research, we validated the T2 W technique performing phantom work and scanning both volunteers and patients to assess the uniformity of signal intensity in the myocardium and to establish a threshold based method to post process the images. We then established a CMR protocol for ACS including oedema imaging, T1 mapping imaging, perfusion, functional and late gadolinium enhancement imaging. Patients with acute myocardial infarction (both ST elevation myocardial infarction (STEMI) and non STEMI) were scanned at 4 different time points after the acute event (3 scans within 2 weeks and one at 6 months). All STEMI patients underwent primary percutaneous coronary intervention (PCI) while the non-STEMI patients underwent coronary angiography and for PCI. Results We validated the T2prep SSFP technique at 3T, highlighting its limitations and establishing a threshold of mean ± 2SD to assess myocardial oedema. We found that the optimal imaging window to assess the maximal expression of myocardial oedema was within 1 week from the acute event in patients with ST elevation MI. Also, our results showed a reduction of LGE over time (from acute to chronic) in segments which also showed improvement in contractile function indicating that even segments with transmural LGE assessed in the early hours post event could be viable. By applying these techniques in acute patients with bystander disease undergoing percutaneous coronary intervention, we found that: l) T2W imaging can detect myocardial injury downstream from a vessel identified as "non culprit" 2) in 20% of NSTEMI patients, the angiographic assessment alone failed to identify the culprit vessel. Finally, we found that the diagnostic performance of acute pre-contrast Tl-mapping was at least as good as that ofT2W CMR for detecting myocardial injury. There was a significant relationship between the segmental damaged fraction assessed by either by LGE or T2W, and mean segmental Tl values and the likelihood of improvement of segmental function at 6 months decreased progressively as acute Tl values increased. Conclusions In summary, we defined a stable imaging window for the retrospective evaluation of area at risk and we also indicated that acutely detected LGE does not necessarily equate with irreversible injury and may severely underestimate salvaged myocardium. Furthermore, in NSTEMI patients with multivessel disease, by revealing acute myocardial damage in territories pertaining to vessels not treated acutely, we raised the issue of the need for better tools for the correct identification of the culprit vessel and to stratify patients rather than by angiographic assessment alone. Finally, we demonstrated how pre-contrast Tl mapping allows for assessment of the extent of myocardial damage and how Tl mapping might become an important complementary technique to LGE and T2W for the identification of reversible myocardial injury and the prediction of functional recovery in acute MI.

Abstract:
This document describes the design, analysis of Orbit Maneuvers and Attitude Control for NanoSat class satellites, which uses an electro-magnetic force controller which was proposed by the Florida Space Institute (FSI). Orbit Maneuvering and the Attitude Control System (ACS) play a very important role for the success of this mission, as that can allow making the satellite go to the desired orbit as well do the sun pointing of the solar arrays with su¢ cient accuracy to achieve desired power levels. The primary mission would be to attain attitude stabilization using the torque from the coils. This is also used for pointing at the direction of the sun, for achieving desired power levels. The secondary mission would be to use the force of the magnetic field and utilize that for orbit maneuvering, and attain the desired trajectory. This thesis gives a presentation of this detailed analysis with a simulation using Matlab/Simulink. Mathematical model of the actuators and sensors used for this satellite are designed, so that the simulation gives us results very near to the actual ones.Health Monitoring is also one of the main issues addressed in this work. This simulation helps us in understanding the mission as well as the requirements very well, and helps us know all the shortcomings. The FUNSAT satellite is modeled as an example in Simulink together with a Kalman filter for attitude estimation based on all sensor measurements. The theory behind this, and extending the Kalman filter, is also presented.

Abstract:
Introduction The TR-24 is relatively new to the cyclotron market and its advantages over lower energy PET cyclotrons have not yet been fully realized. A new high current [18F] fluoride production target that takes advantage of the higher energy and current afforded by the TR-24 has been developed. Material and Methods The TR-24 cyclotron presents challenges of producing conventional PET isotopes even with its variable energy capability (18–25 MeV). Simultaneous irradiation of two targets that require different proton energies is possible only using beam energy degrader. Due to the relatively wide energy window, the degrader design is not trivial, especially for the high current operation. For example, reduction of beam energy from 24 to 18 MeV would require the use of an approximately 1.5 mm thick aluminum degrader. At 100 μA this degrader would have to be capable of dissipating 700 W of beam power, which would be challenging to achieve with no cooling or using a conventional helium cooling window. However, cooling water used as a beam energy degrader can dissipate several kilowatts of beam energy and provide additional cooling for target material and window foils. FIGURE 1 demonstrates the concept of the water cooled target window. A standard 18F- water target with a 2.5 mL fill volume and a 30 degree beam incident angle was modified to accept the new water window. A 1 mm thick region of circulating cooling water was inserted between the vacuum and the product foil. The combined beam energy degradation caused by the vacuum foil (0.00012“ Havar), the cooling water (1 mm) and the target foil (0.00012“ Havar) was approximately 7 MeV for a 24 MeV incident proton energy. The target was installed on a target selector mounted directly on the TR-24 cyclotron. No additional beam focusing or steering devices were used to defocus or correct beam shape. A small recirculation water system was setup to supply cooling water for the degrader. A mixed bed ion exchange column was installed on the return line to trap N-13 and radioactive metal ions that could possibly be etched from the Havar foils. The water in the degrader was continually circulated in a closed loop providing cooling to the vacuum and target foils. An 800mL/min water flow through the degrader was generated by a low pressure water pump. Results Several tests were performed with O-16 water to establish current – pressure curve and to determine “burn through” current (FIGURE 2). Conclusion Initial tests demonstrated that the new F-18 target with a 1 mm water degrader is capable of accepting power levels in excess of 3.6 kW, operating at 150 μA. More testing is under way, including testing with H218O to determine the F-18 production capacity of this target. We will look into adapting this concept to all ACSI PET targets, including the high current F-18 produc-tion target which can potentially reach an operational current of 200 μA.

Acute coronary syndrome consists in a state of clinical symptoms compatible with acute myocardial ischaemia that may result from various thrombotic coronary artery diseases: unstable angina, non–ST-segment elevation acute myocardial infarction and STsegment elevation myocardial infarction. This disease normally occurs due to atherosclerosis, through the rupture of an unstable atherosclerotic plaque or through superficial endothelial erosion. Eventually the activation of the coagulation cascade and platelet adhesion, activation and aggregation ends up leading to acute thrombosis. Risk stratification in patients with acute coronary syndrome is very important in the determination of the proper treatment strategy. Various clinical features are known to be associated with an increased risk of a worse outcome in the event of an acute coronary syndrome and are taken into account in various risk scores. The main aim of this work is the determination of clinical characteristics that are associated with a worse outcome in a group of patients with acute coronary syndrome admitted to the Cardiac Intensive Care Unit of Hospital Infante D. Pedro, in Centro Hospitalar do Baixo Vouga, in order to identify potential prognostic markers in these patients, and the assessment of the association of these markers with other clinical characteristics, in order to determine their influence in the physiology of patients with acute coronary syndrome. A prospective observational study was conducted in 980 patients with acute coronary syndrome admitted to the cardiac intensive care unit of Hospital Infante D. Pedro, in Centro Hospitalar do Baixo Vouga, between January 2008 and June 2012. Data collected was analysed using Student's T-test, One-way Anova, Kruskal-Wallis test, Pearson’s X2 test, Fisher's Exact test, Cox Proportional Hazards Model e Kaplan-Meyer estimate, and included general clinical information and information regarding cardiac risk factors, general blood test, serum cardiac markers, left ventricular ejection fraction, provided revascularization therapy and previous and posterior cardiac events The results obtained indicate that female gender, advanced age, anemia, low left ventricular ejection fraction, the presence of a previous event, hypertension, dyslipidemia and obesity are associated with a poorer prognosis in patients with acute coronary syndrome.
O síndrome coronário agudo consiste num estado de sintomas físicos compatíveis com isquemia miocárdica aguda, podendo resultar de várias doenças arteriais coronárias: angina instável, enfarte agudo do miocárdio sem elevação do segmento-ST e enfarte agudo do miocárdio com elevação do segmento-ST. Esta doença ocorre normalmente devido a aterosclerose, através da rutura de uma placa aterosclerótica instável ou através de erosão endotelial. Eventualmente a ativação da cascata de coagulação e a adesão, ativação e agregação de plaquetas levam a trombose aguda. A estratificação do risco em pacientes com síndrome coronário agudo é muito importante na determinação da estratégia terapêutica adequada. Várias características clínicas estão associadas com um risco aumentado de um prognóstico adverso aquando de um síndrome coronário agudo, sendo tidos em conta em várias tabelas de previsão de risco. O principal objetivo deste trabalho é a determinação de características clínicas associadas com pior um prognóstico num grupo de doentes com síndrome coronário agudo internados na unidade de cuidados intensivos cardíacos do Hospital Infante D. Pedro, no Centro Hospitalar do Baixo Vouga, de forma a identificar potenciais marcadores de prognóstico nestes doentes, e a determinação da sua associação com outras características clínicas, de forma a determinar a sua influência na fisiologia de doentes com síndrome coronário agudo. Levou-se a cabo um estudo prospetivo observacional em 980 doentes com síndrome coronário agudo internados na unidade de cuidados intensivos cardíacos do Hospital Infante D. Pedro, no Centro Hospitalar do Baixo Vouga, entre Janeiro de 2008 e Junho de 2012. A informação recolhida foi analisada usando Student's T-test, One-way Anova, Kruskal-Wallis test, Pearson’s X2 test, Fisher's Exact test, Cox Proportional Hazards Model e Kaplan-Meyer estimate, e incluiu informação clínica geral e informação sobre fatores de risco cardíacos, análise sanguínea geral, marcadores cardíacos séricos, fração de ejeção ventricular esquerda, terapia de revascularização e eventos cardíacos prévios e posteriores. Os resultados obtidos indicam que sexo feminino, idade avançada, baixa fração de ejeção ventricular esquerda, a presença de um evento prévio, hipertensão, dislipidémia e obesidade estão associados com um prognóstico adverso em pacientes com síndrome coronário agudo.

Abstract:
La memòria d'aquesta tesi doctoral s'estructura en un primer capítol on es descriuen els objectius de la tesi i l'organització del treball de recerca. Després, el Capítol 2: Anàlisis factorials de dades es destina a presentar les eines utilitzades en les anàlisis factorials de dades. S'introdueix una anàlisi de tipus general, l'anàlisi canònica per a la comparació de dos grups de variables, i llavors es generalitza per a mes de dos grups. Presentem les anàlisis de correspondències, simples i múltiples, com un cas particular de les anàlisis canòniques, però també des d'una perspectiva més clàssica. Es proporcionen tècniques de representació gràfica - representacions simètriques i Biplots - i el concepte d'inèrcia.

En el Capítol 3: Models loglineals i models gràfics es desenvolupen els models loglineals i els models gràfics, el concepte d'independència condicional i el seu ús. Es desenvolupen, a continuació, la formulació dels models loglineals, les restriccions que els caracteritzen -suma zero o còrner zero- i les relacions de transició. Es realitza un estudi de la influència dels paràmetres en la generació de models, sobretot de la importància del termes de les interaccions sobre els termes independents i els efectes principals. En aquest capítol s'introdueix la deviància, com a raó de versemblança entre dos models, la seva expressió i relació amb l'estadístic χ2 i altres indicadors de divergència de models.

El Capítol 4: Estudi de les inèrcies en anàlisis de correspondències s'inicia amb la relació entre la inèrcia, el coeficient de contingència i la deviància. A continuació, s'estudien les descomposicions de la inèrcia com a contribucions dels individus, modalitats o variables i s'apliquen a l'estudi de matrius quadrades. En referència a les anàlisis de correspondències múltiples de la taula de Burt, es fa la descomposició de les inèrcies per blocs i s'estudia la problemàtica dels blocs diagonals. S'estudien metodologies de tractament i es fa una proposta de metodologia per al tractament de matrius quadrades no simètriques basada en una doble descomposició, per una part en l'anàlisi de la simetria-no simetria i per l'altra utilitzant la reconstitució factorial de la part simètrica, basada en un algorisme k-EM, on k és l'ordre de reconstitució. La reconstitució k-EM pot ser aplicada a les taules diagonals de Burt i ens porta a una anàlisi equivalent al Joint Correspondence Analysis.

En el Capítol 5: ACM respecte un model i ACM condicional es dedica a presentar les ACM sobre un model i l'ACM condicional, on una variable qualitativa externa juga el paper de partició. L'aportació es basa en realitzar l'estudi de la inèrcia i la seva descomposició, en dues parts lligades a la variable condicionadora externa: la inèrcia inter i la inèrcia intra. Es troba la formulació de la distribució i mitjançant aquesta, s'interpreta la importància o no del condicionament. Així doncs, usant l'ACM condicional i els models loglineals estudiem el comportament de la inèrcia en relació al model.

El Capítol 6: ACM multicondicional considera les problemàtiques que genera la implementació de l'ACM multicondicional, ja que no es pot generalitzar trivialment del cas simple. Mitjançant l'estudi de les inèrcies condicionals i els models loglineals es desenvolupa una proposta d'anàlisi multicondicional. Aquests resultats són comparats amb els que s'obtenen en un procés de modelització loglineal. S'aplica la proposta a un exemple en el Capítol 7.

El treball de recerca finalitza amb unes conclusions on es resumeixen les principals aportacions i s'indiquen quines podrien ser algunes línies de recerca futures en aquest camp i s'annexen les macros programades.
The research work memory is structured in a first chapter with the description of the objectives of the doctoral thesis and the research work organization. Then, the Chapter 2 Descriptive factorial analysis is exclusively dedicated to present the tools used in factorial analysis. A general analysis, the canonical analysis, to compare two groups of variables is introduced, and then it is generalized to more than two questions. We present correspondence analysis, simple and multiple, as a particular case of canonical analysis, but we present both methods also from a more classical point of view. We also introduce graphical techniques -symmetric displays and Biplots- and the inertia concept.

Chapter 3 Loglinear and graphical models introduces briefly loglinear models and graphical models, the conditional independence concept and its use. Next, we develop the loglinear model formula and the constraints that characterize the model -zero sum or zero corner treatment- and the transition relations. We make a study of the influence of the parameters over the model generation, especially about the significance of interaction terms over principal and independent terms. In this chapter we introduce the deviance, as a likelihood ratio between two models, its expression and its relation with the χ2 statistic and other model divergence indicators.

In Chapter 4 Study of the inertias in correspondence analysis we start with the relation among inertias, the contingence coefficient and deviance. Next, we study the inertia decomposition as the contribution of each individual, category or variable. It's applied to study the case of square matrices. With reference to the multiple correspondence analysis of the Burt table, we decompose inertia by blocks and we investigate the influence of the blocks of the diagonal. A summary of several treatment methodologies is done. We propose a new methodology to treat squared skew-symmetric matrices, based on a double decomposition, on the one hand, in the symmetry-skew-symmetry analysis and on the other using the factorial reconstitution of the symmetric part, based on a k-EM algorithm, where k is the reconstitution order. The k-EM reconstitution methodology can be applied to the diagonal tables of a Burt table, which leads a result equivalent to Joint Correspondence Analysis.

In Chapter 5 - MCA with respect to a model and conditional MCA- firstly we start presenting MCA with respect to a model. Secondly we discuss conditional MCA, where an external variable plays a partitioning role. The contribution is based on studying the inertia and its decomposition in two parts linked to the external conditioning variables, the inter and intra inertia. Next, we find their distribution function and, by means of this, we can test the significance of the conditioning variable. Therefore, using the conditional MCA and loglinear models introduced before, we study the inertia behaviour with relation to the model and with different relation levels between the variables.

The Chapter 6 -Multiconditional MCA- consideres problems generated by the implementation of multiple conditional analysis, since it is not possible to generalize this definition to the simple conditional case. By means of the study of conditional inertias and loglinear models, we develop our proposal for a multiconditional analysis. These results are compared with the results obtained in a loglinear modelling process. We apply our proposal to a data example in Chapter 7.

The dissertation ends with a chapter of conclusions which sums up our principal contributions and suggests some future research lines in this field of investigation and with the macros programmed and used.

Abstract:
This work aims at utilizing natural resources and recycling materials from aircraft industries to enable their usage in medical and purification applications. The main application for which the materials are tested is the adsorption of bilirubin toxin from the liver of end stage liver failure patients. The two materials of concern are date seeds and carbon fiber reinforced polymers (CFRP). Samples of the materials will be treated to produce activated carbon (AC). Following the preparation of the ACs and chitosan coated ACs, tests are carried out to compare uncoated ACs with chitosan coated ACs. FTIR spectroscopy, TGA, DSC and a Spectrophotometer are utilized in order to characterize the samples obtained. From the data acquired, it is concluded that the chitosan coated ACs have better adsorption than the uncoated ACs. The activated carbon fibers showed the highest efficiency for the adsorption of bilirubin toxin. At an adsorbent dose of 0.8 gm, findings show that 98.4% of bilirubin toxin is adsorbed in samples where ACF is used as the adsorbent while 96.5% remained in samples where DPAC was used as the adsorbent.

Abstract:
Different from traditional accelerometer, multi-threshold acceleration switch can be triggered to different working states by external accelerations without complex auxiliary circuits and controlling elements, which has great application potentials in aerospace, vehicle safety and consumer electronics. In this paper, a novel multi-threshold acceleration switch with anti-overloading function is designed and fabricated by incorporating both magnetic multi-stable structures and compliant cantilever contacts, which also can be used to distinguish specific acceleration pulse. To enhance the contact reliability, the magnetic compliant locking mechanism is introduced to prevent bouncing back phenomenon under overload acceleration. Considering the air-damping and multi-magnetic fields coupling effect, the dynamic design model is proposed for analyzing the nonlinear switch response. Then, threshold accelerations can be determined as ac1 = 3.78g, ac2 = 10.2g and ac3 = 6.95g in one direction while threshold accelerations in opposite direction are ac4 = 4.9g, ac5 = 8.47g and ac6 = 5.6g. The switch shows excellent threshold acceleration detection capability, and the inertial switch keeps open while the external acceleration is 0.2g less than the predefined threshold value. The experimental results show that the threshold acceleration with specific pulse width can be accurately identified, and the switch can bear strong overload acceleration comparing to traditional switches. Consequently, the proposed design method provides a new way for intelligent mechanical inertial sensors.
