Resumen

Abstract The fluid substitution method is used for predicting elastic properties of reservoir rocks and their dependence on pore fluid and porosity. This method makes it possible to predict changes in elastic response of a rock saturation with different fluids. This study focused on the Upper Shallow Marine sandstone reservoirs of five selected wells (MM1, MM2, MM3, MM4, and MM5) in the Bredasdorp Basin, offshore South Africa. The integration of petrophysics and rock physics (Gassmann fluid substitution) was applied to the upper shallow marine sandstone reservoirs for reservoir characterisation. The objective of the study was to calculate the volume of clay, porosity, water saturation, permeability, and hydrocarbon saturation, and the application of the Gassmann fluid substitution modelling to determine the effect of different pore fluids (brine, oil, and gas) on acoustic properties (compressional velocity, shear velocity, and density) using rock frame properties. The results showed average effective porosity ranging from 8.7% to 16.6%, indicating a fair to good reservoir quality. The average volume of clay, water saturation, and permeability values ranged from 8.6% to 22.3%, 18.9% to 41.6%, and 0.096–151.8 mD, respectively. The distribution of the petrophysical properties across the field was clearly defined with MM2 and MM3 revealing good porosity and MM1, MM4, and MM5 revealing fair porosity. Well MM4 revealed poor permeability, while MM3 revealed good permeability. The fluid substitution affected rock property significantly. The primary velocity, Vp, slightly decreased when brine was substituted with gas in wells MM1, MM2, MM3, and MM4. The shear velocity, Vs, remained unaffected in all the wells. This study demonstrated how integration of petrophysics and fluid substitution can help to understand the behaviour of rock properties in response to fluid saturation changes in the Bredasdorp Basin. The integration of these two disciplines increases the obtained results’ quality and reliability.

Resumen

Abstract We have previously reported altered PK requiring significantly higher doses of MMF in pediatric AlloSCT recipients (Osunkwo et al, BBMT 2004). The objective of this study is to further evaluate effects of age and type of conditioning regimen (ablative vs reduced intensity on the PK of MMF in pediatric AlloSCT recipients. From Jan ’04 through April ’05 we have enrolled 21 pediatric AlloSCT recipients in an IRB approved protocol. Mean age 6.2 yrs (0.33–15); weight 28.6 kg (5.7–129.3); M:F = 11:10; NBL PR (n=3), SCD (n=2), AML (CR1 [n=2], CR2 [n=1], CR3 [n=1], relapsed [n=1], induction failure [n=1]), SAA (n=2), CML CP (n=1), ALL (CR1 [n=1], CR2 [n=1], CR3 [n=1]), WAS (n=1), HD CR2 (n=1), ALCL refractory (n=1), SCID (n=1); donor sources included MFD (6/6 PBSC [n=5], 6/6 BM [n=1], 5/6 PBSC [n=2]), 6/6 related CB (n=1), UCB (6/6 [n=2], 5/6 [n=2], 4/6 [n=7]), and 8/10 MUD PBSC (n=1). Cohort 1 (< 6 yrs) (n=10); 2 (6–12 yrs of age) (n=6); 3 (12–16 yrs) (n=5). GVHD prophylaxis included tacrolimus and MMF (+ methotrexate for MUD). Tacrolimus was initiated on Day −1 or 1st day of conditioning (protocol dependent) at 0.03 mg/kg/d CI or 0.12 mg/kg/d PO Q8–12H to maintain concentrations 5–20 ng/mL. MMF was initiated on Day +1 at 900 mg/m2/dose IV Q6H and then converted to PO (same dose) on Day +14 or later. MMF PK was performed on Day +1, +7, and +14 (while on IV MMF) at hour 0, 0.5, 1, 2, 3, 4, and 6 post-dose. MPA plasma concentrations were determined by reverse-phase HPLC. MMF dose was adjusted to maintain MPA trough 1–3.5 mcg/mL. The mean CD34+ cell dose/kg = 23 x 105, nucleated cell dose/kg = 45 x 107. Time to neutrophil engraftment (ANC ≥ 500/mm3 x 2 d) was 22 d and platelet engraftment (untransfused count ≥ 20K x 7 d) was 28 d. The mean f/u was 241 d. Mean MPA PK on Day +14 demonstrated Cmax=12.4 mg/L, total MPA trough =0.9 mg/L, AUC0–12=32.7 mcg•hr/mL, Css=2.7 mg/L, T1/2=1.5 h, Vss=1.8 L/kg, and CL=1.4 L/kg/h at a mean MMF dose of 1080 mg/m2 IV Q6H. The breakdown of age cohorts is shown in Table 1. Gastrointestinal adverse events attributable to MMF occurred in 50% of patients (grade 2–3 nausea (n=9), grade 2–3 vomiting (n=4), abdominal pain (n=2), pneumatosis intestinalis (n=1), colitis (n=1)). Kaplan-Meier probability of grade II–IV aGVHD (18 evaluable pts) was 71.1% (CI: 46.9–95.4) and cGVHD (15 evaluable pts) was 37.7% (CI: 8.2–67.1). In comparison to MMF PK in adult AlloSCT pts receiving cyclosporine/MMF (Nash et al, BBMT 2005), pediatric pts appear to have significantly higher MMF clearance rates (1.4 vs 0.54 L/kg/h). MMF doses > 3-fold higher than those used in pediatric SOT recipients were required to achieve AUC0–12=30–60 mcg•h/mL. Short half-life (1.5 hrs) and rapid clearance of MMF in pediatric AlloSCT recipients in part appear related to a lack of enterohepatic recycling and enhanced UDP-glucuronosyltransferase activity.

Resumen

ObjectiveTo investigate whether the use of mycophenolate mofetil (MMF) could reduce the relapse risk in patients with myelin oligodendrocyte glycoprotein (MOG)-immunoglobulin G (IgG)-associated disorders (MOGADs).MethodsThis prospective observational cohort study included patients with MOGAD at Peking Union Medical College Hospital between January 1, 2017, and April 30, 2019. The patients were divided into 2 groups: those with (MMF+) or without (MMF−) MMF therapy. The primary outcome was relapse at follow-up. We used Cox proportional hazards models to calculate hazard ratios (HRs) for relapse.ResultsSeventy-nine patients were included in our MOG cohort. Fifty (63.3%) were adults at index date, and 47 (59.5%) were women. Fifty-four (68.4%) were in the MMF+ group, and 25 (31.6%) were in the MMF− group. Clinical and demographic factors, MOG-IgG titer, and follow-up time (median, 472.5 days for MMF+, 261.0 days for MMF−) were comparable between the groups. Relapse rates were 7.4% (4/54) in the MMF+ group and 44.0% (11/25) in the MMF− group. Of all potential confounders, only the use of MMF was associated with reduced risk of relapse. The HR for relapse among patients in the MMF+ group was 0.14 (95% CI, 0.05–0.45) and was 0.08 (95% CI, 0.02–0.28) in a model adjusted for age, sex, disease course, and MOG-IgG titer. MMF therapy also remained associated with a reduced relapse risk in sensitivity analyses. Only one patient (1.9%) discontinued MMF therapy because of adverse effect.ConclusionsThese findings provide a clinical evidence that MMF immunosuppression therapy may prevent relapse in patients with MOGAD.Classification of evidenceThis study provides class IV evidence that for patients with MOGAD, MMF reduces relapse risk.

Resumen

Transient administration of ANG II causes persistent salt-sensitive hypertension associated with arteriolopathy, interstitial inflammation, and cortical vasoconstriction; blocking the vascular and inflammatory changes with mycophenolate mofetil (MMF) prevents vasoconstriction. While infiltrating leukocytes during the salt-sensitive hypertension phase express ANG II, the functional role of ANG II during this phase is not known. We examined the acute effect of candesartan on renal hemodynamics during the established salt-sensitive hypertensive phase and related these findings to direct measurement of intrarenal ANG II and inflammatory cells in rats previously exposed to ANG II with or without MMF treatment. Sham controls were also examined. The administration of ANG II, followed by exposure to high-salt diet, resulted in hypertension, cortical vasoconstriction, an increase in interstitial inflammatory cells (44.8 ± 1.3 lymphocytes/mm2, and 30.8 ± 1.2 macrophages/mm2 ANG II vs. 19.6 ± 2 lymphocytes/mm2, and 22 ± 0.7 macrophages/mm2 Sham), and increase in renal ANG II levels (1,358 ± 74.6 pg/ml ANG II vs. 194 ± 9.28 pg/ml Sham). Treatment with MMF during the administration of exogenous ANG II resulted in reduction in renal interstitial inflammation (19.7 ± 0.9 lymphocytes/mm2 and 15.9 ± 0.8 machophages/mm2), ANG II levels (436.9 ± 52.29 pg/ml), cortical vasoconstriction, and stable blood pressure levels during the subsequent challenge with a high-salt diet. Acute administration of candesartan similarly reduced renal vasoconstriction and blood pressure. We conclude that the cortical vasoconstriction occurring with salt-sensitive hypertension following exposure to ANG II is mediated by intrarenal ANG II, related, at least in part, to the interstitial inflammation.

Resumen

ABSTRACT Investigating the physical and chemical structure of massive star-forming regions is critical for understanding the formation and early evolution of massive stars. We performed a detailed line survey toward six dense cores, named MM1, MM4, MM6, MM7, MM8, and MM11, in the G9.62+0.19 star-forming region resolved in Atacama Large Millimeter/submillimeter Array (ALMA) band 3 observations. Toward these cores, about 172 transitions have been identified and attributed to 16 species, including organic oxygen-, nitrogen-, and sulphur-bearing molecules and their isotopologues. Four dense cores, MM7, MM8, MM4, and MM11, are line-rich sources. Modelling of these spectral lines reveals that the rotational temperature lies in the range 72–115, 100–163, 102–204, and 84–123 K for MM7, MM8, MM4, and MM11, respectively. The molecular column densities are 1.6 × 1015–9.2 × 1017 cm−2 toward the four cores. The cores MM8 and MM4 show a chemical difference between oxygen- and nitrogen-bearing species, i.e. MM4 is rich in oxygen-bearing molecules, while nitrogen-bearing molecules, especially vibrationally excited HC3N lines, are mainly observed in MM8. The distinct initial temperatures at the accretion phase may lead to this N/O differentiation. Through analysing column densities and spatial distributions of O-bearing complex organic molecules (COMs), we found that C2H5OH and CH3OCH3 might have a common precursor, CH3OH. CH3OCHO and CH3OCH3 are likely chemically linked. In addition, the observed variation in HC3N and HC5N emission may indicate their different formation mechanisms in hot and cold regions.

Resumen

Context: Metatarsal stress fractures are common in cleated-sport athletes. Previous authors have shown that plantar loading varies with footwear, sex, and the athletic task. Objective: To examine the effects of shoe type and sex on plantar loading in the medial midfoot (MMF), lateral midfoot (LMF), medial forefoot (MFF), middle forefoot (MidFF), and lateral forefoot (LFF) during a jump-landing task. Design: Crossover study. Setting: Laboratory. Patients or Other Participants: Twenty-seven recreational athletes (14 men, 13 women) with no history of lower extremity injury in the last 6 months and no history of foot or ankle surgery. Main Outcome Measure(s): The athletes completed 7 jumping trials while wearing bladed-cleat, turf-cleat, and running shoes. Maximum force, contact area, contact time, and the force-time integral were analyzed in each foot region. We calculated 2 × 3 analyses of variance (α = .05) to identify shoe-condition and sex differences. Results: We found no shoe × sex interactions, but the MMF, LMF, MFF, and LFF force-time integrals were greater in men (P < .03). The MMF maximum force was less with the bladed-cleat shoes (P = .02). Total foot and MidFF maximum force was less with the running shoes (P < .01). The MFF and LFF maximum forces were different among all shoe conditions (P < .01). Total foot contact area was less in the bladed-cleat shoes (P = .01). The MMF contact area was greatest in the running shoes (P < .01). The LFF contact area was less in the running shoes (P = .03). The MFF and LFF force-time integrals were greater with the bladed-cleat shoes (P < .01). The MidFF force-time integral was less in the running shoes (P < .01). Conclusions: Independent of shoe, men and women loaded the foot differently during a jump landing. The bladed cleat increased forefoot loading, which may increase the risk for forefoot injury. The type of shoe should be considered when choosing footwear for athletes returning to activity after metatarsal stress fractures.

Resumen

Objective.Small series suggest mycophenolate mofetil (MMF) is well tolerated and may be an effective therapy for connective tissue disease-associated interstitial lung disease (CTD-ILD). We examined the tolerability and longitudinal changes in pulmonary physiology in a large and diverse cohort of patients with CTD-ILD treated with MMF.Methods.We identified consecutive patients evaluated at our center between January 2008 and January 2011 and prescribed MMF for CTD-ILD. We assessed safety and tolerability of MMF and used longitudinal data analyses to examine changes in pulmonary physiology over time, before and after initiation of MMF.Results.We identified 125 subjects treated with MMF for a median 897 days. MMF was discontinued in 13 subjects. MMF was associated with significant improvements in estimated percentage of predicted forced vital capacity (FVC%) from MMF initiation to 52, 104, and 156 weeks (4.9% ± 1.9%, p = 0.01; 6.1% ± 1.8%, p = 0.0008; and 7.3% ± 2.6%, p = 0.004, respectively); and in estimated percentage predicted diffusing capacity (DLCO%) from MMF initiation to 52 and 104 weeks (6.3% ± 2.8%, p = 0.02; 7.1% ± 2.8%, p = 0.01). In the subgroup without usual interstitial pneumonia (UIP)-pattern injury, MMF significantly improved FVC% and DLCO%, and in the subgroup with UIP-pattern injury, MMF was associated with stability in FVC% and DLCO%.Conclusion.In a large diverse cohort of CTD-ILD, MMF was well tolerated and had a low rate of discontinuation. Treatment with MMF was associated with either stable or improved pulmonary physiology over a median 2.5 years of followup. MMF appears to be a promising therapy for the spectrum of CTD-ILD.

Resumen

An interference filter is designed by fusing a segment of multi-core fiber (MCF) between two segments of multimode fibers (MMFs), which is then spliced between two segments of single mode fibers (SMFs). The light is split into the cladding and different cores of the MCF through the first segment of MMF, which is then coupled back into the core of SMF by the second segment of MMF. When the lengths of MCF are selected to be 4 mm and 10 mm, the 3 dB bandwidths of the filters around 1060 nm are 8.40 nm and 4.84 nm, respectively. Applying these filters in an Yb-doped fiber laser mode-locked by nonlinear polarization rotation, stable pulses have been obtained. Compared with the reported interference filters, the filter proposed in this paper has the advantages of simple fabrication process, compact structure and high environmental stability.

Resumen

This master's thesis is focused on the issues of stress testing in the context of financial stability. It consists of two major parts. The first part deals with methodology of general stress tests with special regard to stressed indicators and relevant risks. In the second part, the difficulties and shortcomings of general stress tests are analysed with respect to the dynamic expansion of financial instruments and markets. A special attention is paid to integrate liquidity risk and contagion risk into the current stress testing framework. Furthermore, the alternative instruments for increasing the complexity of banks financial soundness analysis are presented. It can be said that the system of financial stability analysis before the crisis was not sufficient because it did not reflect on all risk exposures. The main contribution of this thesis is the organized presentation of possible solutions which would help to enhance the quality of stress testing outputs and to a certain extent unify these outputs as well.

Resumen

Because of its limited bandwidth Multi-Mode Fibre (MMF) was until recently thought unsuitable to carry high dynamic range RF modulated ranges. Although it was observed that the response of a laser-based MMF shows a passband response with only little attenuation beyond the 3 dB-bandwidth, researchers have found this passband response to be very unstable and segmented by deep troughs. In this work a controlled launch technique is proposed, which results in stable and low-penalty transmission over the majority of installed-base MMF links. It was found that more than 99 % of all 62.5 μm core-diameter MMFs (62MMF) in the installed base will support RF carrier frequencies up to at least GHz over distances of up to 600 m. Furthermore, low-penalty transmission is possible beyond 1000 m for a smaller percentage of fibres. It is also shown that the tolerance on the launch position is large enough to allow for a low-cost design of the optical components. Further, a number of semiconductor lasers, designed for uncooled digital applications, were assessed in terms of their analogue modulation performance. It was found that different laser structures (DFB, EP and VCSEL) exhibit sufficiently linearity performance for analogue operation with a typical spurious-free dynamic range (SFDR) of at least 90 dB ^. Hz^2/3, even when operated uncooled at elevated temperatures of 85 °C, which is a value high enough to support most current in-building wireless systems. Finally it is shown for the first time that low-bandwidth MMF and low-cost digital lasers can be combined for the implementation of high-speed analogue optical links. A link analysis was carried out which showed that even with passband losses of up to 24 dBe, which is the maximum attenuation observed in 99 % of the installed base 62MMF, a high dynamic range RoF system with a SFDR of above 95 dB ^. Hz^2/3 can be designed. A link is presented which supports the transmission of RF signals at carrier frequencies of up to 20 GHz with very little penalty, using a directly modulated laser diode and both low- and high-bandwidth MMF.

Resumen

The construction of Baku-Tbilisi-Ceyhan (BTC) Oil and South Caucasus Gas (SCP) pipelines was completed in 2005. The Azerbaijan section of BTC Oil and SCP Gas pipelines is 442 km long and 44 m wide corridor named as the Right-of-Way. BTC and SCP pipelines are aligned parallel to each other within the same 44m corridor. The construction process of the pipelines significantly disturbed vegetation and soil cover along Right-of-Way of pipelines. The revegetation and erosion control measures were conducted after the completion of construction to restore the disturbed footprints of construction activities. The general goals of the present studies, dedicated to the environmental monitoring of revegetation and planning of erosion control measures were: to evaluate the status of the revegetation in 2007 since the completion of the construction activities in 2005, to determine the climate and ground factors controlling the vegetation regrowth and to predict erosion-prone areas along Right-of-Way of pipelines. Regression and root mean square error analysis between the Normalized Difference Vegetation Index (NDVI) of IKONOS images acquired in 2007 and in-situ estimations of vegetation cover percentage revealed R2 equal to 0.80 and RMSE equal to 6% which were optimal for the normalization of NDVI to vegetation cover. The total area of restored vegetation cover between 2005 and 2007 was 8.9 million sq. m. An area of 10.7 million sq. m. of ground vegetation needed restoration in order to comply with the environmental acceptance criteria. Based on the Global Spatial Regression Model, precipitation, land surface temperature and evapotranspiration were determined as the main climate factors controlling NDVI of grasslands along Right-of-Way of pipelines. In case of croplands, precipitation, evapotranspiration and annual minimum temperature were determined as the main factors controlling NDVI of croplands. The regression models predicting NDVI for grasslands and croplands were also formulated. The Geographically Weighted Regression analyses in comparison with the global regression models results clearly revealed that the relationship between NDVI of grasslands and croplands and the predictor variables was spatially non-stationary along the corridor of pipelines. Even though the observed R2 value between elevation and NDVI of grasslands was low (R2= 0.14), the accumulation of the largest NDVI patterns was observed higher than 150m elevation. This revealed that elevation has non-direct control of NDVI of grasslands through its control of precipitation and temperature along the grasslands of Right-of-Way. The spatial distribution percentage of NDVI classes within slope aspect categories was decreasing in the southern directions of slope faces. Land surface temperature was decreasing with elevation but no particular patterns of land surface temperature in the relationship with NDVI accumulation within the aspect categories were observed. Aspect categories have non-direct control of NDVI and there are some other factors apart from land surface temperature which require further investigations. Precipitation was determined to be controlling the formation of topsoil depth and the topsoil obviously controls the VC growth of grasslands as one of the main ground factors. The regression analysis between NDVI of grasslands and croplands with groundwater depth showed very low correlation. But the clustered patterns of vegetation cover were observed in the relationship with groundwater depth and soil moisture for both grasslands and croplands. The modeling of groundwater depth relative to soil moisture and MODIS NDVI of grasslands determined that the threshold of groundwater depth for vegetation growth is in the range of 1-5 m. MODIS NDVI and soil moisture did not reveal a significant correlation. Soil moisture revealed R2 equal to 0.34 with elevation, R2 equal to 0.23 with evapotranspiration, R2 equal to 0.57 with groundwater depth and R2 equal to 0.02 with precipitation. This allowed to suspect that precipitation is not the main factor controlling soil moisture whereas elevation, evapotranspiration and groundwater depth have non-direct control of soil moisture. Therefore, soil moisture has also non-direct control of vegetation cover growth along the corridor of pipelines. The variations of soil moisture in the 1-3 m soil depth range may have the threshold of depth controlling vegetation cover regrowth and this requires more detailed soil moisture data for further investigations. The reliability of the Global Spatial Regression Model and Geographically Weighted Regression predictions is limited by the MODIS images spatial resolution equal to 250 m and spectral characteristics. The Morgan-Morgan-Finney (MMF) and Universal Soil Loss Equation (USLE) predictions revealed non-similarity in the spatial distribution of soil loss rates along Right-of-Way. MMF model revealed more clustered patterns of predicted critical erosion classes with soil loss more than 10 ton/ha/year in particular ranges of pipelines rather than Universal Soil Loss Equation model with the widespread spatial distribution. Paired-Samples T-Test with p-value less than 0.05 and Bivariate correlation with the Pearson\'s correlation coefficient equal to 0.23 showed that the predictions of these two models were significantly different. Verification of USLE- and MMF- predicted erosion classes against in-situ 316 collected erosion occurrences collected in the period of 2005-2012 revealed that USLE performed better than MMF model along pipeline by identifying of 192 erosion occurrences out of 316, whereas MMF identified 117 erosion sites. USLE revealed higher ratio of frequencies of erosion occurrences within the critical erosion classes (Soil Loss > 10 t/ha), what also showed higher reliability of soil loss predictions by USLE. The validation of quantitative soil loss predictions using the measurements from 48 field erosion plots revealed higher R2 equal to 0.67 by USLE model than by MMF. This proved that USLE-predicted soil loss rates were more reliable than MMF not only in terms of spatial distributions of critical erosion classes but also in the quantitative terms of soil loss rates. The total number of erosion-prone pipeline segments with the identified erosion occurrences was 316 out of 38376. The number of erosion-prone pipeline segments realistically predicted by USLE model e.g. soil loss more than 10 t/ha was 97 whereas MMF predicted only 70 erosion-prone pipeline segments. The regression analysis between 354 USLE and MMF erosion-prone segments revealed R2 equal to 0.36 what means that the predictions by USLE and MMF erosion models are significantly different on the level of pipeline segments. The average coefficients of variation of predicted soil loss rates by USLE and MMF models and the number of accurately predicted erosion occurrences within the geomorphometric elements of terrain, vegetation cover and landuse categories were larger in the USLE model. This supported the hypothesis that larger spatial variations of erosion prediction models can contribute to the better soil loss prediction performance and reliability of erosion prediction models. This also supported the hypothesis that better understanding of spatial variations within geomorphometric elements of terrain, land-use and vegetation cover percentage classes can support in the selection of the appropriate erosion models with better performance in the particular areas of pipelines. Qualitative multi-criteria assessment for the determination of erosion-prone areas revealed stronger relations with the USLE predictions rather than with MMF. Multi-criteria assessment identified 35 of erosion occurrences but revealed more reliable predictions on the level of terrain units. Predicted erosion-prone areas by USLE revealed higher correlation coefficient with erosion occurrences than MMF model within terrain units what proved higher reliability of the USLE predictions and its stronger relation with the multi-criteria assessment.

Resumen

This thesis focuses on the economic impact of the financial crisis that Argentina suffered between 2001 and 2002. It mainly analyses how the government approached such situation. The Currency Board regime ended and was substituted by a floating regime. Also many emergency measures were adopted in order to avoid even more chaotic situations. This thesis also deals with fiscal and monetary policy adopted in the longer term, which more or less until today reflexes the consequences of the crisis, i.e. fight against inflation, market regulation and sovereign debt towards official institutions and private investors.

Texto completo

Resumen

The thesis describes a new technique, called the flux-MMF diagram technique, for analysis and comparative evaluation of electrical machines. The technique has evolved from the principle of virtual work, and the -i diagram, used commonly in designing switched reluctance machines and relays. Several applications of this technique are demonstrated in the thesis, supported by experimental validation. These are, the prediction of electromagnetic and cogging torque ripple, modelling of the effect of skew on torque and torque ripple, modelling of the variation of torque constant due to saturation, and comparative evaluation of different types of electrical machines. The thesis shows that the technique can be applied successfully in analysis of a wide variety of electrical machines. These include conventional machines such as the DC commutator, PM brushless AC, Interior PM, and the synchronous reluctance machine; as well as non-conventional machines such as the switched reluctance, PM brushless DC, and the doubly-salient PM machine. The technique has been implemented in a finite-element software, with the help of a link program which links the FE software with the dimensioning or sizing software, such as PC-BDC, produced by the SPEED Laboratory. The link program serves as a vital means of shortening the time it takes to analyse a new design in an FE software, by several orders of magnitude. The thesis also describes a new brushless doubly-salient permanent-magnet machine, called the flux-reversal machine. The design and fabrication process, and the experimental results are presented for a prototype single-phase, high-speed flux-reversal generator. The performance analysis of the prototype based on the flux-MMF diagram technique is included, and this validates its capability in analysing new and non-conventional machines, which cannot be analysed using the classical means.

Resumen

AbstractChronic GVHD (cGVHD) is the most relevant cause of late non-relapse morbidity and subsequent mortality (approximately 25%) following allo-HCT (Grube et al. 2016). Its incidence is approximately 50% among all patients following allo-HCT and has increased during the last two decades due to increasing patient age and increasing use of unrelated and/or mismatched donors, RIC regimens, PBSC with application of standard GVHD prophylaxis (calcineurin inhibitor [CNI] + MMF or MTX) only (Arai et al. 2015). While the incidence of cGVHD is lower (6–40%) in children, its incidence rises to 60% as age increases (Baird et al. 2010; Sobkowiak-Sobierajska et al. 2022).

Resumen

Introdução: O lúpus eritematoso sistêmico (LES) é uma doença que afeta principalmente mulheres em idade reprodutiva, e a nefrite lúpica (NL) é uma manifestação frequente, com um aumento do risco de complicações. O micofenolato de mofetil (MMF) é um medicamento imunossupressor e é atualmente considerado o tratamento de primeira linha para NL. No entanto, desde o relato do primeiro caso de malformação congênita associada ao uso materno do MMF na década de 1990, esses imunossupressores têm sido evitados em pacientes que planejam engravidar. Objetivo: Avaliar os desfechos fetais e neonatais em pacientes com LES que engravidaram enquanto faziam uso de MMF, por meio de uma análise retrospectiva dos prontuários médicos. Métodos: Foram analisados todos os prontuários de pacientes com LES em busca daquelas que engravidaram enquanto estavam em uso de MMF, no período de 2009 a 2020. Resultados e discussão: Estudos anteriores sugeriram que a presença de abortamentos ou malformações poderia estar relacionada à dose de MMF e à duração do uso da medicação. Em relação aos casos de abortamento, o tempo de uso do MMF foi de 4, 8 e 16 semanas, e a dose utilizada foi de 1,5 g/dia. No caso em que o recém-nascido apresentou malformações esqueléticas, o tempo de uso do MMF foi de 10 semanas, e a dose prescrita era de 3 g/dia, a maior dose relatada. Das 20 pacientes estudadas, 4 (20%) tiveram abortos espontâneos, e das 16 pacientes que não abortaram, 1 recém-nascido (6,25%) apresentou malformações ao nascer, sendo compatíveis com anomalias ósseas. Estudos anteriores indicaram que anomalias ósseas estavam presentes em 23% dos fetos com embriopatias relacionadas ao MMF. Um pequeno estudo prospectivo de 10 casos relatou que, com a exposição ao MMF no primeiro trimestre da gestação, nenhum dos neonatos nasceu com malformações, mas 40% sofreram aborto espontâneo. Esse estudo sugere que a taxa real de embriopatias associadas ao MMF possa estar entre 4 e 6%, o que se assemelha aos achados do presente estudo. Também é possível que os fetos que sofreram aborto espontâneo tivessem malformações maiores que não foram identificadas. Outro fator que dificulta a análise adequada do impacto do MMF é o fato de que o LES apresenta taxas aumentadas de aborto espontâneo, principalmente em casos de NL e atividade da doença. Conclusão: A presença de nefrite lúpica por si só é um marcador de mau prognóstico materno-fetal. O uso de MMF parece aumentar o risco de aborto espontâneo e teratogenicidade quando usado durante a gestação. Neste estudo, observou-se que, das 20 pacientes estudadas, 4 (20%) tiveram abortos espontâneos e, entre as 16 pacientes que não abortaram, 1 recém-nascido (6,25%) apresentou malformações ao nascer.

Resumen

Abstract Banyu Urip reservoir management heavily rely on river-sourced water as water injection to meet Voidage Replacement Ratio target of 1. The treatment facility which consist of Raw Water Basin, Clarifiers, Multi Media Fine (MMF) Filters and Cartridge Filters, is sensitive to seasonal transition and river condition. This paper shares lesson learnt in operating such facility and troubleshooting guidance to overcome challenges of high turbidity during rainy season and lack of river water volume during drought season. To maintain the design intent of Banyu Urip (BU) water treatment facility in achieving water injection quality and quantity at reasonable cost, following activities were undertaken: [1] Critical water parameters data gathering & analysis across each unit; [2] Clarifier Chemical injection dosage verification based on laboratory test; [3] MMF Media coring inspection to assess the filtering media condition; [4] MMF Filters backwash parameters optimization; [5] MMF Filter on-off valve sequencing optimization to address water hammering issue; [6] Water injection rate management to deal with river water source availability along the year. Critical water parameters analysis revealed that chemical dosages were in-adequate to treat the five times higher turbidity coming into Clarifiers during early rain 2019. On top of this, low Raw Water Basin level at the end of long drought further contributed to jeopardize Clarifier's operation. Although in-adequate chemicals injection was resolved at early 2020, the treatment cost remained high, especially on filtration section. Media coring result on MMF Filters confirmed that the filtering media have been poisoned by carried-over mud from Clarifiers during upset. The operation of MMF Filters required extensive optimization on backwash parameters to successfully recover the MMF Filters performance without media replacement. Latest media coring on the worst MMF Filter showed that there was no more top mud layer and the amount of trapped mud had been decreased significantly. Cartridge Filter replacement interval was improved from 38 hours to 186 hours, therefore water treatment cost dropped with quite significant margin. Additionally, the availability of each MMF Filters was also improved. At the same time, the high water injection rate during 2020 rainy season, had successfully increased reservoir pressure buffer up to its maximum point as the anticipation of prolonged drought season. This paper provides the troubleshooting guidance for MMF Filter application in season-prone water treatment facility including insights on interpretation of media coring result and linking it back to optimization strategy on the MMF Filters drain down time for effective backwash process without having excessive media loss.

Resumen

Optical fiber shape sensing are important measurement technologies in applications such as healthcare, structural monitoring and robotics. Current state-of-the-art optical fiber shape sensing requires complex sensor structures and interrogation systems. We recently demonstrated that the multimode fiber (MMF) output speckles contain its geometric shape information of the MMF itself. In this paper, we will introduce our recently progresses in this direction, including using machine learning in a proof-of-concept three-dimensional (3D) multi-point deformation sensing via a single MMF, and soft waveguide-based shape sensing. Our results show that a single MMF/soft waveguide based deformation sensor possesses the advantage in terms of system simplicity and sensitivity. It has the potential in deformation monitoring or shape-sensing applications.
