1. Cold highly charged ions in a radio-frequency trap with superconducting magnetic shielding

Abstract: We implement sympathetic cooling of highly charged ions (HCI) by fully enclosing a linear Paul trap within a superconducting radio-frequency resonator. A quantization magnetic field applied while cooling down into the superconducting state remains present in the trap for centuries and external electromagnetic fluctuations are greatly suppressed. A magnetic field decay rate at the 10$^{-10}$ s$^{-1}$ level is found using trapped Doppler-cooled Be$^+$ ions as hyperfine-structure (hfs) qubits. Ramsey interferometry and spin-echo measurements on magnetically-sensitive hfs transitions yield coherence times of >400 ms, showing excellent passive shielding at frequencies down to DC. For sympathetic cooling of HCI, we extract them from an electron beam ion trap (EBIT) and co-crystallize one together with Doppler-cooled Be$^+$ ions. By subsequently ejecting all but one Be$^+$ ions, we prepare single HCI for quantum logic spectroscopy towards frequency metrology and qubit operations with a great variety of HCI species., Comment: 16 pages, 19 figures.

2. Sensorless MPPT Algorithms for PV Systems in Partially Shaded Scenarios

Author: Guilherme M. S. Martines, Moacyr A. G. de Brito, Edson A. Batista, Ruben B. Godoy, and Tiago H. A. Mateus
Subjects: MPPT, sensorless, metaheuristic, reduced cost, partial shading conditions, photovoltaic arrays, Electrical engineering. Electronics. Nuclear engineering, TK1-9971
Abstract: This manuscript presents current sensorless algorithms for maximum power point tracking (MPPT) in partially shaded photovoltaic (PV) systems. The necessity of a current sensor is eliminated with the use of mathematical modeling of the power electronics converter. This approach significantly reduces the implementation cost and the inherent disadvantages in the current sensor circuitry. MPPT techniques based on soft computing are employed, in addition to Perturb and Observe (P&O), due to their ability to explore a larger search space. This feature is advantageous because it minimizes convergence risk to a local maximum, a limitation of traditional techniques. Simulation and experimental results are presented and each algorithm is evaluated through different metrics, such as search time for the global maximum power point (GMPP) and efficiency. The tests consider dynamic irradiance profiles, producing a tracking factor (TF) above 99% and a remarkable fast convergence time.

Abstract: Summary: Background: Although immunomodulators have established benefit against the new coronavirus disease (COVID-19) in general, it is uncertain whether such agents improve outcomes without increasing the risk of secondary infections in the specific subgroup of previously immunocompromised patients. We assessed the effect of immunomodulators on outcomes of immunocompromised patients hospitalized for COVID-19. Methods: The protocol was prospectively registered with PROSPERO (CRD42022335397). MEDLINE, Cochrane Central Register of Controlled Trials and references of relevant articles were searched up to 01-06-2022. Authors of potentially eligible randomized controlled trials were contacted to provide data on immunocompromised patients randomized to immunomodulators vs control (i.e., placebo or standard-of-care). Findings: Eleven randomized controlled trials involving 397 immunocompromised patients hospitalized for COVID-19 were included. Ten trials had low risk of bias. There was no difference between immunocompromised patients randomized to immunomodulators vs control regarding mortality [30/182 (16.5%) vs 41/215 (19.1%); RR 0.93, 95% CI 0.61–1.41; p = 0.74], secondary infections (RR 1.00, 95% CI 0.64–1.58; p = 0.99) and change in World Health Organization ordinal scale from baseline to day 15 (weighed mean difference 0.27, 95% CI -0.09–0.63; p = 0.15). In subgroup analyses including only patients with hematologic malignancy, only trials with low risk of bias, only trials administering IL-6 inhibitors, or only trials administering immunosuppressants, there was no difference between comparators regarding mortality. Interpretation: Immunomodulators, compared to control, were not associated with harmful or beneficial outcomes, including mortality, secondary infections, and change in ordinal scale, when administered to immunocompromised patients hospitalized for COVID-19.

7. An efficient transformation method for genome editing of elite bread wheat cultivars

Author: Akshaya K. Biswal, L. Ruben B. Hernandez, Ana I. R. Castillo, Juan M. Debernardi, and Kanwarpal S. Dhugga
Subjects: wheat, transformation, GRF4-GIF1, particle bombardment, gene editing, CRISPR-Cas, Plant culture, SB1-1110
Abstract: An efficient genetic transformation protocol is necessary to edit genes for trait improvement directly in elite bread wheat cultivars. We used a protein fusion between a wheat growth-regulating factor 4 (GRF4) and its interacting factor (GIF1) to develop a reproducible genetic transformation and regeneration protocol, which we then used to successfully transform elite bread wheat cultivars Baj, Kachu, Morocco, Reedling, RL6077, and Sujata in addition to the experimental cultivar Fielder. Immature embryos were transformed with the vector using particle bombardment method. Transformation frequency increased nearly 60-fold with the GRF4-GIF1-containing vectors as compared to the control vector and ranged from ~5% in the cultivar Kachu to 13% in the cultivar RL6077. We then edited two genes that confer resistance against leaf rust and powdery mildew directly in the aforementioned elite cultivars. A wheat promoter, TaU3 or TaU6, to drive the expression of guide RNA was effective in gene editing whereas the OsU3 promoter failed to generate any edits. Editing efficiency was nearly perfect with the wheat promoters. Our protocol has made it possible to edit genes directly in elite wheat cultivars and would be useful for gene editing in other wheat varieties, which have been recalcitrant to transformation thus far.

8. The Influence Gap: Unequal Policy Responsiveness to Men and Women.

Author: Mathisen, Ruben B.
Subjects: *GOVERNMENT policy, *WOMEN in politics, *GENDER differences (Sociology), *PUBLIC opinion
Abstract: Despite decades of research on women's representation, we still know surprisingly little about the extent to which public policy responds unequally to the preferences of women and men. This article exploits two comparable data sets, one for the United States and one for Norway, together containing measures of gender-disaggregated public opinion, as well as public policy outcomes, on 2,650 specific proposals asked about in survey polls between 1964 and 2014. The data reveal a substantial gap in policy responsiveness to men and women (in favor of men) in both countries. However, in Norway, the gender gap has virtually disappeared over time, a development that appears to be attributable to the increasing share of women in parliament. In the United States, the gap has remained remarkably stable over time. [ABSTRACT FROM AUTHOR]

10. Differential-Evolution-Assisted Optimization of Classical Compensation Topologies for 1 W Current-Fed IMD Wireless Charging Systems

Author: Ianca M. S. de Jesus, Thaís M. Tolfo, Ruben B. Godoy, Matheus de C. Pelzl, Beatriz de S. Acosta, and Rafael L. R. Soares
Subjects: implantable medical devices (IMDs), wireless power transfer, Differential-Evolution-based algorithm, Technology, Engineering (General). Civil engineering (General), TA1-2040, Biology (General), QH301-705.5, Physics, QC1-999, Chemistry, QD1-999
Abstract: Implantable medical devices (IMDs) necessitate a consistent energy supply, commonly sourced from an embedded battery. However, given the finite lifespan of batteries, periodic replacement becomes imperative. This paper addresses the challenge by introducing a wireless power transfer system designed specifically for implantable medical devices (IMDs). It begins with a detailed analysis of the four conventional topologies. Following this, the paper provides a thorough explanation for choosing the PS topology, highlighting its advantages and suitability for the intended application. The primary parallel capacitance necessitates power from current sources; thus, a Class-E amplifier was implemented. Additionally, the selected circuit was engineered to deliver 1 W at the biocompatible resonance frequency of 13.56 MHz. The delineation of the resonance parameters hinges on multifaceted solutions, encompassing bifurcation-free operation and the attainment of peak efficiency. To ensure the feasibility of the proposed solution, a Differential-Evolution-based algorithm was employed. The results obtained from simulation-based evaluations indicated that the system achieved an efficiency exceeding 86%. This efficiency level was maintained even in the face of frequency fluctuations and variations in the coupling between the coils, thereby ensuring stable operational performance. This aligns seamlessly with the specified application prerequisites, guaranteeing a feasible and reliable operation.

13. A 600 W Photovoltaic Groundwater Pumping System Based on LLC Converter and Constant Voltage MPPT

Author: Flavio Palmiro, Ruben B. Godoy, Tiago H. d. A. Mateus, and Nicholas D. de Andrade
Subjects: photovoltaic water pumping, resonant DC-DC converter, constant voltage MPPT, Technology
Abstract: The work consists of the development of a market-friendly 600 W photovoltaic battery-less water pumping system. The system is composed of four 280 Wp solar panels, an auxiliary 10 W solar panel, a three-phase converter and a ½ horsepower (hp) submersible water pump. The electronic stage involves a resonant DC-DC converter in series with a voltage source three-phase inverter. The novelties of this work are related to the use of a resonant DC-DC converter with fixed duty-cycle and frequency for water pumping application, the use of Silicon Carbide Metal-Oxide-Semiconductor Field-Effect Transistors (MOSFETs) for solving converter startup issues, and the use of a constant voltage maximum power tracking (MPPT) algorithm with auxiliary panels. The work displays the design of the converter, simulation and experimental results, discussions, and cost evaluation. The feasibility of the system is studied for the water requirements of a beef cattle farm in Brazil.

14. Current Sensorless Based on PI MPPT Algorithms

Author: Moacyr A. G. de Brito, Guilherme M. S. Martines, Anderson S. Volpato, Ruben B. Godoy, and Edson A. Batista
Subjects: controllers, MPPT, reduced cost, sensorless, Chemical technology, TP1-1185
Abstract: This paper presents novel current sensorless maximum-power point-tracking (MPPT) algorithms based on compensators/controllers and a single-input voltage sensor. The proposed MPPTs eliminate the expensive and noisy current sensor, which can significantly reduce the system cost and retain the advantages of the widely used MPPT algorithms, such as Incremental Conductance (IC) and Perturb and Observe (P&O) algorithms. Additionally, it is verified that the proposed algorithms, especially the proposed Current Sensorless V based on PI, can reach outstanding tracking factors (TFs) such as the IC and P&O based on PI algorithms. In this sense, the insertion of controllers inside the MPPT gives them adaptive characteristics, and the experimental TFs are in the remarkable range of more than 99%, with an average yield of 99.51% and a peak of 99.80%.

15. Differential Evolution and Fuzzy-Logic-Based Predictive Algorithm for V2G Charging Stations

Author: Lucas G. da Silva, Nicholas D. de Andrade, Ruben B. Godoy, Moacyr A. G. de Brito, and Emilio T. Maddalena
Subjects: V2G applications, differential evolution algorithm, fuzzy controller, charging optimization, Technology, Engineering (General). Civil engineering (General), TA1-2040, Biology (General), QH301-705.5, Physics, QC1-999, Chemistry, QD1-999
Abstract: This work proposes a differential evolution algorithm to control a vehicle-to-grid (V2G) system based on photovoltaic generation and energy cost curves, and constraints associated with the power converters’ operation, battery charging strategy, and initial budgets. The algorithm is designed to trade off the batteries’ state of charge and the profits gained from selling energy to the grid. To achieve this balance, a fuzzy controller is employed and acts based on forecasts of the photovoltaic generation and the cost of electricity, within prediction windows of 120 min, adapting the batteries’ rate of charging or discharging. Simulation results show that for different curves and different initial budgets, the target state of charge is reached at the end of the time horizon. By evaluating the proposed scheme under different scenarios, the algorithm’s performance is proven to be suitable for future practical deployment.

Author: Nicholas D. de Andrade, Ruben B. Godoy, Edson A. Batista, Moacyr A. G. de Brito, and Rafael L. R. Soares
Subjects: active parallel power filter, FPGA-in-the-loop, modern power theories, Technology
Abstract: This work compares the performance of two embedded FPGA controllers that can be used in Active Parallel Power Filters (APPF). Both controllers are validated through the FPGA-in-the-loop (FIL) technique, the algorithm’s synthesis is accomplished using the Quartus II® platform, and the board used is from Altera®—Cyclone IV DE2-115. The main difference between the controllers resides in the power theories used to obtain the currents for compensation. The results confirm that the FPGA is a suitable digital device for the parallel operation of multiple compensators and calculation stages, being a viable solution for the requirements imposed in the control of APPF. Furthermore, the effectiveness of the FIL technique for validating the operation of digital circuits and control systems is also confirmed. Finally, a comparison between the processing costs of each of the implemented power theories is presented to guide novel proposals.

21. Observational relationships between ammonia, carbon dioxide and water vapor under a wide range of meteorological and turbulent conditions: RITA-2021 campaign.

Subjects: CARBON dioxide in water, WATER vapor, LAND-atmosphere interactions, TURBULENT mixing, WATER pressure, LATENT heat, ATMOSPHERIC carbon dioxide, AMMONIA
Abstract: We present a comprehensive observational approach that aims to establish relationships between the surface–atmosphere exchange of ammonia (NH3) and CO2 uptake and transpiration by vegetation. In doing so, we study relationships useful for the improvement and development of NH3 flux representations in models. The NH3 concentration and flux are measured using a novel open-path miniDOAS (differential optical absorption spectroscopy) measurement setup, taken during the 5-week Ruisdael Land–Atmosphere Interactions Intensive Trace-gas and Aerosol measurement (RITA-2021) campaign (25 August until 12 October 2021) at the Ruisdael Observatory in Cabauw, the Netherlands. After filtering for unobstructed flow, sufficient turbulent mixing and CO2 uptake, we find the diurnal variability in the NH3 flux to be characterized by daytime emissions (0.05 µgm-2s-1 on average) and deposition at sunrise and sunset (-0.05 µgm-2s-1 on average). We first compare the NH3 flux to the observed gross primary production (GPP), representing CO2 uptake, and latent heat flux (LvE), representing net evaporation. Next, we study the observations following the main drivers of the dynamic vegetation response, which are photosynthetically active radiation (PAR), temperature (T) and the water vapor pressure deficit (VPD). Our findings indicate the dominance of the stomatal emission of NH3 , with a high correlation between the observed emissions and both LvE (0.70) and PAR (0.72), as well as close similarities in the diurnal variability in the NH3 flux and GPP. However, efforts to establish relationships are hampered by the high diversity in the NH3 sources of the active agricultural region and the low data availability after filtering. Our findings show the need to collocate meteorological, carbon and nitrogen studies to advance our understanding of NH3 surface exchange and its representation. [ABSTRACT FROM AUTHOR]

22. Sampling Rate Impact on Electrical Power Measurements Based on Conservative Power Theory

Author: Larissa R. Souza, Ruben B. Godoy, Matheus A. de Souza, Luigi G. Junior, and Moacyr A. G. de Brito
Subjects: accurate measurements, Conservative Power Theory, sampling rate, Technology
Abstract: This article presents a study of the sampling rate effect on electrical power measurements whose definitions are based on the Conservative Power Theory (CPT). The definitions of active power and reactive power of the CPT were applied in the MATLAB® software by varying the sampling rate and using a digital power meter as a reference. The measurements were performed in scenarios with linear and non-linear loads. Due to the usage of an integral in the CPT calculus, an error was verified associated with the reactive power being inversely proportional to the sampling rate. From the present study, it is possible to conclude that depending on the sample rate, the errors associated with the reactive power measurements are unacceptable and make the CPT implementation unfeasible. The results also presented effective information about the minimal sampling rate needed to make these errors neglected and to assist in choosing suitable microprocessors for the digital implementation of the CPT. It is worth mentioning that this paper was limited to assess how accurate the measurements of active and reactive powers were and important to highlight that the CPT has the additional contribution of dealing with distortion currents and consequently new portions of powers. For the latter, the influence of sampling rate may be crucial and new lines of investigation are motivated.

Abstract: Implantable medical devices (IMDs) necessitate a consistent energy supply, commonly sourced from an embedded battery. However, given the finite lifespan of batteries, periodic replacement becomes imperative. This paper addresses the challenge by introducing a wireless power transfer system designed specifically for implantable medical devices (IMDs). It begins with a detailed analysis of the four conventional topologies. Following this, the paper provides a thorough explanation for choosing the PS topology, highlighting its advantages and suitability for the intended application. The primary parallel capacitance necessitates power from current sources; thus, a Class-E amplifier was implemented. Additionally, the selected circuit was engineered to deliver 1 W at the biocompatible resonance frequency of 13.56 MHz. The delineation of the resonance parameters hinges on multifaceted solutions, encompassing bifurcation-free operation and the attainment of peak efficiency. To ensure the feasibility of the proposed solution, a Differential-Evolution-based algorithm was employed. The results obtained from simulation-based evaluations indicated that the system achieved an efficiency exceeding 86%. This efficiency level was maintained even in the face of frequency fluctuations and variations in the coupling between the coils, thereby ensuring stable operational performance. This aligns seamlessly with the specified application prerequisites, guaranteeing a feasible and reliable operation. [ABSTRACT FROM AUTHOR]

Abstract: We sympathetically cool highly charged ions (HCI) in Coulomb crystals of Doppler-cooled Be+ ions confined in a cryogenic linear Paul trap that is integrated into a fully enclosing radio-frequency resonator manufactured from superconducting niobium. By preparing a single Be+ cooling ion and a single HCI, quantum logic spectroscopy toward frequency metrology and qubit operations with a great variety of species are enabled. While cooling down the assembly through its transition temperature into the superconducting state, an applied quantization magnetic field becomes persistent, and the trap becomes shielded from subsequent external electromagnetic fluctuations. Using a magnetically sensitive hyperfine transition of Be+ as a qubit, we measure the fractional decay rate of the stored magnetic field to be at the 10−10 s−1 level. Ramsey interferometry and spin-echo measurements yield coherence times of >400 ms, demonstrating excellent passive magnetic shielding at frequencies down to DC. [ABSTRACT FROM AUTHOR]

The novelties of this work are related to the use of a resonant DC-DC converter with fixed duty-cycle and frequency for water pumping application, the use of Silicon Carbide Metal-Oxide-Semiconductor Field-Effect Transistors (MOSFETs) for solving converter startup issues, and the use of a constant voltage maximum power tracking (MPPT) algorithm with auxiliary panels. The work displays the design of the converter, simulation and experimental results, discussions, and cost evaluation. The feasibility of the system is studied for the water requirements of a beef cattle farm in Brazil. [ABSTRACT FROM AUTHOR]

28. An efficient transformation method for genome editing of elite bread wheat cultivars.

Author: Biswal, Akshaya K., Hernandez, L. Ruben B., Castillo, Ana I. R., Debernardi, Juan M., and Dhugga, Kanwarpal S.
Abstract: An efficient genetic transformation protocol is necessary to edit genes for trait improvement directly in elite bread wheat cultivars. We used a protein fusion between a wheat growth-regulating factor 4 (GRF4) and its interacting factor (GIF1) to develop a reproducible genetic transformation and regeneration protocol, which we then used to successfully transform elite bread wheat cultivars Baj, Kachu, Morocco, Reedling, RL6077, and Sujata in addition to the experimental cultivar Fielder. Immature embryos were transformed with the vector using particle bombardment method. Transformation frequency increased nearly 60-fold with the GRF4-GIF1-containing vectors as compared to the control vector and ranged from ~5% in the cultivar Kachu to 13% in the cultivar RL6077. We then edited two genes that confer resistance against leaf rust and powdery mildew directly in the aforementioned elite cultivars. A wheat promoter, TaU3 or TaU6, to drive the expression of guide RNA was effective in gene editing whereas the OsU3 promoter failed to generate any edits. Editing efficiency was nearly perfect with the wheat promoters. Our protocol has made it possible to edit genes directly in elite wheat cultivars and would be useful for gene editing in other wheat varieties, which have been recalcitrant to transformation thus far.

Subjects: ALGORITHMS, TRACKING algorithms, VOLTAGE, DETECTORS
Abstract: This paper presents novel current sensorless maximum-power point-tracking (MPPT) algorithms based on compensators/controllers and a single-input voltage sensor. The proposed MPPTs eliminate the expensive and noisy current sensor, which can significantly reduce the system cost and retain the advantages of the widely used MPPT algorithms, such as Incremental Conductance (IC) and Perturb and Observe (P&O) algorithms. Additionally, it is verified that the proposed algorithms, especially the proposed Current Sensorless V based on PI, can reach outstanding tracking factors (TFs) such as the IC and P&O based on PI algorithms. In this sense, the insertion of controllers inside the MPPT gives them adaptive characteristics, and the experimental TFs are in the remarkable range of more than 99%, with an average yield of 99.51% and a peak of 99.80%.

Abstract: This work proposes a differential evolution algorithm to control a vehicle-to-grid (V2G) system based on photovoltaic generation and energy cost curves, and constraints associated with the power converters' operation, battery charging strategy, and initial budgets. The algorithm is designed to trade off the batteries' state of charge and the profits gained from selling energy to the grid. To achieve this balance, a fuzzy controller is employed and acts based on forecasts of the photovoltaic generation and the cost of electricity, within prediction windows of 120 min, adapting the batteries' rate of charging or discharging. Simulation results show that for different curves and different initial budgets, the target state of charge is reached at the end of the time horizon. By evaluating the proposed scheme under different scenarios, the algorithm's performance is proven to be suitable for future practical deployment. [ABSTRACT FROM AUTHOR]

31. A Polymorph of Dipeptide Halide Glycyl-L-Alanine Hydroiodide Monohydrate: Crystal Structure, Optical Second Harmonic Generation, Piezoelectricity and Pyroelectricity.

Subjects: SECOND harmonic generation, POLYMORPHISM (Crystallography), CRYSTAL structure, PYROELECTRICITY, PIEZOELECTRICITY, TRIGLYCINE sulfate
Abstract: A polymorph of glycyl-L-alanine HI.H2O is synthesized from chiral cyclo-glycyl-L-alanine dipeptide. The dipeptide is known to show molecular flexibility in different environments, which leads to polymorphism. The crystal structure of the glycyl-L-alanine HI.H2O polymorph is determined at room temperature and indicates that the space group is polar (P21), with two molecules per unit cell and unit cell parameters a = 7.747 Å, b = 6.435 Å, c = 10.941 Å, α = 90°, β = 107.53(3)°, γ = 90° and V = 520.1(7) Å3. Crystallization in the polar point group 2, with one polar axis parallel to the b axis, allows pyroelectricity and optical second harmonic generation. Thermal melting of the glycyl-L-alanine HI.H2O polymorph starts at 533 K, close to the melting temperature reported for cyclo-glycyl-L-alanine (531 K) and 32 K lower than that reported for linear glycyl-L-alanine dipeptide (563 K), suggesting that although the dipeptide, when crystallized in the polymorphic form, is not anymore in its cyclic form, it keeps a memory of its initial closed chain and therefore shows a thermal memory effect. Here, we report a pyroelectric coefficient as high as 45 µC/m2K occurring at 345 K, one order of magnitude smaller than that of semi-organic ferroelectric triglycine sulphate (TGS) crystal. Moreover, the glycyl-L-alanine HI.H2O polymorph displays a nonlinear optical effective coefficient of 0.14 pm/V, around 14 times smaller than the value from a phase-matched inorganic barium borate (BBO) single crystal. The new polymorph displays an effective piezoelectric coefficient equal to d e f f = 280 p C N − 1 , when embedded into electrospun polymer fibers, indicating its suitability as an active system for energy harvesting.

Abstract: Research from the United States and Europe suggests that affluent citizens enjoy considerably more policy influence than do average citizens and the poor. I examine the extent of unequal policy responsiveness in one of the countries that have gone farthest in reducing economic inequality and restricting money in politics: Norway. I use an original dataset on public opinion and public policy containing 603 specific issues over five decades (1966–2014). The results show that although policy is certainly skewed toward the preferences of the privileged, Norway stands out among previously studied cases for two reasons: (1) The preferences of the poor seem to have some sway on economic issues and (2) not all affluent citizens get their way: educational attainment appears to be the more important determinant. The Norwegian case suggests that influence need not be as dependent upon affluence as in the United States. [ABSTRACT FROM AUTHOR]

36. Intra-Section Analysis of Human Coronary Arteries Reveals a Potential Role for Micro-Calcifications in Macrophage Recruitment in the Early Stage of Atherosclerosis.

Subjects: Medicine, Science
Abstract: Vascular calcification is associated with poor cardiovascular outcome. Histochemical analysis of calcification and the expression of proteins involved in mineralization are usually based on whole section analysis, thereby often ignoring regional differences in atherosclerotic lesions. At present, limited information is available about factors involved in the initiation and progression of atherosclerosis.This study investigates the intra-section association of micro-calcifications with markers for atherosclerosis in randomly chosen section areas of human coronary arteries. Moreover, the possible causal relationship between calcifying vascular smooth muscle cells and inflammation was explored in vitro.To gain insights into the pathogenesis of atherosclerosis, we performed analysis of the distribution of micro-calcifications using a 3-MeV proton microbeam. Additionally, we performed systematic analyses of 30 to 40 regions of 12 coronary sections obtained from 6 patients including histology and immuno-histochemistry. Section areas were classified according to CD68 positivity. In vitro experiments using human vascular smooth muscle cells (hVSMCs) were performed to evaluate causal relationships between calcification and inflammation.From each section multiple areas were randomly chosen and subsequently analyzed. Depositions of calcium crystals at the micrometer scale were already observed in areas with early pre-atheroma type I lesions. Micro-calcifications were initiated at the elastica interna concomitantly with upregulation of the uncarboxylated form of matrix Gla-protein (ucMGP). Both the amount of calcium crystals and ucMGP staining increased from type I to IV atherosclerotic lesions. Osteochondrogenic markers BMP-2 and osteocalcin were only significantly increased in type IV atheroma lesions, and at this stage correlated with the degree of calcification. From atheroma area type III onwards a considerable number of CD68 positive cells were observed in combination with calcification, suggesting a pro-inflammatory effect of micro-calcifications. In vitro, invasion assays revealed chemoattractant properties of cell-culture medium of calcifying vascular smooth muscle cells towards THP-1 cells, which implies pro-inflammatory effect of calcium deposits. Additionally, calcifying hVSMCs revealed a pro-inflammatory profile as compared to non-calcifying hVSMCs.Our data indicate that calcification of VSMCs is one of the earliest events in the genesis of atherosclerosis, which strongly correlates with ucMGP staining. Our findings suggest that loss of calcification inhibitors and/or failure of inhibitory capacity is causative for the early precipitation of calcium, with concomitant increased inflammation followed by osteochondrogenic transdifferentiation of VSMCs.

Abstract: The current paradigm reads that calcifications characterize the advanced and complex lesions in the atherosclerotic process. To explore the possibility that coronary artery wall calcifications already commence at an early stage of atherosclerosis, a combination of proton beam techniques with a (sub-) micrometer resolution, i.e., micro-proton induced X-ray emission, backward and forward scattering spectroscopy, was applied on human coronary arteries with lesions preceding overt atheromas. The detection limits of phosphorus and calcium in each separate pixel, 0.88 * 0.88 [micro][m.sup.2] in size, were approximately 150 and 80 [micro]/g dry weight, respectively. Calcium distributions of entire coronary artery cross section were obtained, and calcifications were demonstrated at a preatheroma stage of the atherosclerotic process. The size of the microcalcifications varied between 1 and 10 [micro]m. The composition of the microcalcifications was deduced from the calcium-to-phosphorus ratio. In order to quantify this ratio, the thickness of the specific X-ray absorber used for PIXE had to be accurately determined. Also, thick target PIXE calculations were performed and the method was validated. The calcium-to-phosphorus ratios of the microcalcifications were assessed with good accuracy and varied from 1.62 to 2.79, which corresponds with amorphous calcium phosphate.

Abstract: The problem of mechanical instability and poor barrier properties of relief stamps for microcontact printing (muCP) is addressed by developing new stamp designs. It is shown that the local oxidation of flat PDMS stamps and their subsequent modification with perfluoroalkyl groups is an effective route to solve these problems without compromising intrinsic advantages of the technique which include ease of use and the potential for a high cost efficiency.

Abstract: Este trabalho propõe um sistema de medição e uma metodologia de modelação para a avaliação de erros de medição em medidores de energia elétrica ativa do tipo indução e eletrônico. O sistema de medição propicia condições distintas de distorções harmônicas para tensões e correntes nos testes experimentais, além de permitir o emprego de formas de onda de tensões equilibradas ou desequilibradas (3% e 5%). As formas de onda empregadas nos testes experimentais são provenientes de um banco de dados composto por medições em consumidores com diferentes características de carga (industrial, comercial, rural e residencial). A metodologia para modelação dos erros de medição é baseada na utilização de dados experimentais provenientes do sistema de medição proposto, evitando as incertezas de modelação relacionadas com a idealização e não modelação de parâmetros comportamentais, especialmente quando o modelo de erro de medição é determinado de maneira totalmente teórica, e consideradas condições não senoidais.

Abstract: This study presents a fine-scale simulation approach to assess the representativity of ammonia (NH 3) measurements in the proximity of an emission source. Close proximity to emission sources (< 5 km) can introduce a bias in regionally representative measurements of the NH 3 molar fraction and flux. Measurement sites should, therefore, be located a significant distance away from emission sources, but these requirements are poorly defined and can be difficult to meet in densely agricultural regions. This study presents a consistent criterion to assess the regional representativity of NH 3 measurements in proximity to an emission source, calculating variables that quantify the NH 3 plume dispersion using a series of numerical experiments at a fine resolution (20 m). Our fine-scale simulation framework with explicitly resolved turbulence enables us to distinguish between the background NH 3 and the emission plume, including realistic representations of NH 3 deposition and chemical gas–aerosol transformations. We introduce the concept of blending distance based on the calculation of turbulent fluctuations to systematically analyze the impact of the emission plume on simulated measurements, relative to this background NH 3. We perform a suite of systematic numerical experiments for flat homogeneous grasslands, centered around the CESAR Observatory at Cabauw, to analyze the sensitivity of the blending distance, varying meteorological factors, emission/deposition and NH 3 dependences. Considering these sensitivities, we find that NH 3 measurements at this measurement site should be located at a minimum distance of 0.5–3.0 and 0.75–4.5 km from an emission source for NH 3 molar fraction and flux measurements, respectively. The simulation framework presented here can easily be adapted to local conditions, and paves the way for future ammonia research to integrate simulations at high spatio-temporal resolutions with observations of NH 3 concentrations and fluxes.

Subjects: conversor push-pull, Inversor monofásico, modulação em três níveis, Electrical engineering. Electronics. Nuclear engineering, TK1-9971
Abstract: O objetivo deste trabalho é apresentar uma topologia de um inversor push-pull de três níveis, denominado push-pull modificado. Algumas topologias com o mesmo objetivo já foram propostas [2-3], mas, em geral, não apresentam vantagens em relação a um inversor de ponte completa. A simplicidade é a principal vantagem dos conversores push-pull, o que os torna atrativos para aplicações de baixa potência. O inversor proposto é obtido adicionando-se apenas uma chave ao push-pull padrão. Esta nova topologia permite controle completo de três níveis, utilizando menor quantidade de chaves comparado a um inversor de ponte completa. Primeiramente, a topologia do inversor será apresentada e, então, os passos de operação serão descritos, mostrando os princípios de operação e as leis de controle. Uma comparação entre quatro topologias de inversores também é apresentada. Finalmente, simulações e resultados experimentais são mostrados para a validação da topologia. Esse novo inversor é viável para aplicações com baixas tensões de entrada e que demandam modulação de três níveis, como em sistemas de geração distribuída baseada em energia renovável.

48. Protocolo de Santa María sobre jurisdicción internacional en materia de relaciones de consumo

Author: Ruben B. Santos Belandro
Subjects: mercosur, consumidores, protección del consumidor, protocolo de Santa María, Law in general. Comparative and uniform law. Jurisprudence, K1-7720, Social sciences (General), H1-99
Abstract: Afirmar que vivimos en una sociedad de consumo no es un simple eufemismo sino una realidad que sentimos y vivimos en cada situación en la que nos vemos involucrados. Ello se debe a que ha finalizado la época del autoabastecimiento y en un mundo cada vez más complejo y diversificado la interdependencia es un elemento indispensable para que el factor económico tenga pujanza. El consumismo puede desenvolverse dentro de la sociedad de cada Estado; es notable ver cómo las relaciones de consumo han sido el ámbito preferido de regulación en el continente latinoamericano, generalmente dotadas de normas de policía o de aplicación inmediata. Consumo y arbitraje han sido los temas seleccionados por el legislador nacional a la hora de actualizar sus ordenamientos jurídicos. (...) Contenido: Antecedentes. El Protocolo de Santa María.

Abstract: Al modelo de Estado del siglo XVIII que asumía como únicas funciones la de juez para la solución de los litigios entre los particulares y de gendarme con el objetivo de preservar lapaz pública, le sucedió en los primeros 50 años de nuestro siglo la concepción de un Estado intervencionista -denominado también welfare state o Estado Bienestar- en el que se le otorgó una mayor atención al bienestar de sus habitantes mediante una gestión directa de numerosos sectores de la economía, al privilegio en el desarrollo de aquellas áreas más deprimidas, a la distribución intencional de los recursos sociales en favor de los desprotegidos económicamente, etc (...)

Abstract: El grupo de países europeos que se encuentra comprometido en el proceso de integración económica formuló hace ya tiempo, los criterios para determinar las bases de competencia a fi~ de resolver los litigios de derecho privado que pudieran surgir en dicho espacio geográfico. El documento elaborado fue el Convenio de Bruselas sobre competencia judicial y ejecución de las resoluciones en materia civil y mercantil del 27 de setiembre de 1968. Sin embargo, en dicho momento no fue posible regular las bases de competencia en los procedimientos civiles que se vinculaban conlos temas del divorcio, de la separación legal de los cónyuges y acerca de las cuestiones relacionadas conla nulidad del matrimonio (...)
