Memórias da Vila Dique: saúde, história e cidadania (2012)

A Vila Dique e uma area de ocupacao irregular da periferia de Porto Alegre, proxima ao Aeroporto Internacional Salgado Filho. Com a ampliacao do aeroporto, a remocao das familias iniciou, com modificacoes importantes nas vidas dos moradores. Tambem a Unidade de Saude Santissima Trindade (USST) do Servico de Saude Comunitaria (SSC) do Grupo Hospitalar Conceicao (GHC), que estabelece uma relacao de mais de 18 anos de atencao a saude nesse territorio, sera removida. Do desejo de profissionais de saude, usuarios e liderancas da comunidade surgiu o Projeto Memorias da Vila Dique. Em parceria com o curso de Historia da UFRGS, o projeto pretende resgatar e socializar a construcao da historia da Vila Dique a partir do olhar de seus proprios moradores e dos trabalhadores da saude. Iniciou com uma acao de extensao sendo contemplado com recursos em que se conseguiram bolsistas, a futura publicacao de um album fotografico e a constituicao de um acervo com possibilidade de acesso a todos. Pretende-se incentivar ou fortificar redes de apoio na area a ser removida e na area do reassentamento, refletir, socializar e publicizar historias e reflexoes sobre a remocao. Muito importante neste momento, o papel da USST que se coloca ao lado da comunidade na escuta e na partilha de perdas e ganhos, fortalecendo lacos. A metodologia e a roda de memoria e, ate entao, aconteceram duas rodas de moradores. Ha o planejamento e execucao das rodas, transcricao e analise dos relatos, bem como estudo de textos. Tudo isso em constante dialogo academia-servico-comunidade. Apos as duas rodas, relatos levaram a ampliacao da dimensao do trabalho. Para alem da remocao, o Projeto lanca a possibilidade da permanencia da escuta: um espaco de memoria – possivelmente na nova USST - em que cada um possa contar um pouco de si. Cabe explicar que acoes sao pensadas na tentativa de reunir memoria e saude. Um exemplo e o curso de fotografia que sera oferecido as gestantes. No caso, alem do resgate e registro, acoes de educacao em saude estao sendo pensadas para esse grupo. A experiencia esta proporcionando trocas valiosas, relatos de melhora da autoestima de usuarios, satisfacao em rememorar e reencontrar parceiros, o que reforca o objetivo de proporcionar um espaco de cuidado e escuta. Uma experiencia rica que permite enxergar herois de uma comunidade marcada com o rotulo da marginalidade, pessoas que podem, compartilhando historias, redesenharem seus espacos e suas vidas.
Feasibility study of CO2 capture by anti-sublimation (2011)

Processes for carbon capture and storage have the drawback of high energy demand. In this work the application of CO2 capture by anti-sublimation is analyzed. The process was simulated using Aspen Plus. Process description is accomplished by phase equilibria models which are able to reproduce the vapor-liquid and vapor-solid equilibria. Different process configurations are proposed. Total electric energy demand was defined as the evaluation criteria and the most suitable configuration was selected within technical limits. Further performance enhancement was achieved by improving the compression cooling cycles. An economic evaluation was performed for the low temperature process and the results were compared to a chemical absorption process with monoethanolamine. CO2 capture by anti-sublimation showed a better performance concerning the energy demand but with a reduced economic benefit due to higher equipment cost.
Stimulation of insulin secretion from pancreatic islets by the cholecystokinin-tetrapeptide analogs Trp-Pro-Asp-Phe-NH2 and Trp-Pro-Asp-Phe(4'-NO2)-NH2. (1992)

The cholecystokinin-tetrapeptide (CCK4) analogs Trp-Pro-Asp-Phe-NH2 (3) and Trp-Pro-Asp-Phe-(4'-NO2)-NH2 (4) were found to be nearly equipotent to cholecystokinin-octapeptide (CCK8) in potentiating glucose-induced insulin secretion from islets of Langerhans isolated from rat pancreas. This stimulatory action was found to be dose-dependent and, in the case of 4, to exhibit a biphasic dose-response curve; i.e., at concentrations greater than 1.0 nM, the stimulating effect of 4 is reversed. These results suggest that conformational restriction of CCK4 and/or modification of the phenylalanine residue could produce more potent analogs capable of stimulating insulin release. Such compounds could have potential therapeutic utility in the treatment of non-insulin-dependent diabetes mellitus (NIDDM).
Survey of performance issues in parallel database systems (2003)

Parallel database systems are being used nowadays in a wide variety of systems, right from database applications to decision support systems. These implementations involve database processing and querying over parallel systems. For the parallel databases to be effective and efficient, various optimizing solutions need to be implemented. These solutions deal with various issues associated with such database systems : query optimization, data allocation within the database, etc.This paper will attempt to give the reader an understanding of the various issues involved in optimizing the performance of a parallel database system. The primary areas of focus will be system architecture, query optimization and data reallocation. It will look at related work done by other authors in this field and hopefully provide a thorough understanding of the solutions in this area.
使用Visual Studio 2005速成版建立低廉的开发环境 (2005)

写基于Windows的应用程序的第一次尝试在脑海里只留下了模糊的记忆。当时是使用C语言在286机器上编写。实际上我曾经尝试从脑子里清除掉这段经历。要知道我最初是使用COBOL和RPG在HP 3000mini上编程的，相对而言为Windows编程太痛苦了。
SCRAD modulation: high data rate space shift keying scheme permitting reduced-complexity detector (2012)

This reported work elaborates a novel spatial-domain modulation scheme for multi-antenna wireless communication transceivers, dubbed as Symbol Coordinate Representations in Antenna Domains (SCRAD) modulation, which achieves better error performance compared to other schemes such as spatial modulation and generalised space shift keying at the same data rate. Specifically, the coordinate representing message in a signal constellation is depicted on the transmit-antenna array by leveraging activation patterns and binary phase shift keying signals. In addition, a reduced-complexity detector with maximum-likelihood performance is developed based on the unique signal structure of SCRAD modulation.
Oedema is associated with clinical outcome following emergency abdominal surgery (2013)

Generalised oedema is common after emergency abdominal surgery and appears to independently predict gastrointestinal recovery, the need for artificial nutritional support and survival. Oedema is not associated with commonly applied markers of nutritional status such as body mass index or recent weight loss. Measurement of oedema offers utility in identifying those at risk of poor clinical outcome or those requiring artificial nutritional support following emergency abdominal surgery.
Progress in semicrystalline heat-resistant polyamides (2018)

Abstract For the past decade, market demands for semicrystalline heat-resistant polyamides (HPAs) with excellent performance and significantly improved heat-resistant temperature has grown rapidly, and they are widely used in the electronic and electrical industry, as light-emitting diodes and in the automobile field (as metal replacements). Industrialized HPAs to date, include PA46, PA6T copolyamides, PA9T and PA10T. Other HPAs being researched include full aliphatic HPA, PA5T, long carbon chain HPA, PXD10 and alicyclic HPA. This review addresses progress in HPAs, especially the properties of HPA, patents analysis and polymerization processes.
Kinetics and Stereochemistry of Elimination of Nitrous-Acid From 1-Para-Nitrophenyl-2-Nitroethyl Derivatives (1986)

The eliminations of nitrous acid from the compounds (1) and (6) are E2 processes, which proceed with a large primary kinetic isotope effect and with antiperiplanar stereochemistry. The rate of elimination of HNO2 from (1) is intermediate between the rate of elimination of HCl from (4) and HBr from (5). This order of nucleofugality , namely Br- &gt; NO2- &gt; Cl -, results from a more positive entropy of activation for the elimination of nitrous acid. The presence of an a-chlorine, as in compounds (8), (28) and (29), leads to elimination processes which are E1cB-like, with low primary kinetic isotope effects and with lack of stereospecificity.
Healthy living. (2017)

There is a hierarchy of determinants (sometimes incorrectly called 'causes') of the major modern chronic dieases. These are summarised under the acronym NASTIE MAL ODOURS and collectively under the term 'anthropogens', which are '… man-made environments and the lifestyles associated with these, many of which may lead to disease'. Attention to anthropogens in a systems fashion suggest guidelines for modern healthy living.
Research of Tire Rolling Radius Based On the Finite Vibration Unit Model (2013)

This paper established the finite vibration unit model and solved the response of each unit system. And it analyzed the unit vibration. Based on the model it introduced the calculation method of rolling radius. Next this paper simulated rolling radius and the relationships between the rolling radius and the vehicle speed, the tire pressure, and the load using MATLAB software. And the relationships were modified according to the real vehicle test. Finally, the tire rolling radius calculation method was discovered at high speed.
Procedure for Making a Cement Mixture with Recycled Plastics Applicable to the Manufacture of Building Elements (2010)

This review is about the Argentina Patent number AR 047617B1 published on August 12, 2008. Its inventors are Gaggino Rosana, Arguello Ricardo and Berretta Horacio. The topic is a procedure to make new constructive elements (bricks and plates) by using these recycled plastics: - Low-density polyethylene (LDPE), recycled out of discarded soft drink packs. - Polyethylene-terephthalate (PET), recycled out of discarded soft drink bottles. - Several plastics, from the printed films used, like packages of candies (remainder of production plant by faults of inked or thickness). These conveniently grounded plastics were taken as aggregates to be mixed with Normal Portland cement, replacing heavy sand and gravel habitually used in these mixtures. These materials can be used in constructive elements such as bricks and plates for economic houses closures or traditional construction. The developed constructive elements offer high thermal insulation, so they can be used in closures with a smaller thickness than conventional bricks and blocks. Besides, they have a lower specific weight than these traditional constructive elements. Recycling means lowering costs, making part of the environment contaminating waste useful and providing the unemployed and/or unqualified work force with jobs through uncomplicated technologies. Therefore, it has an economical as well as ecological and socially concerned proposal. Keywords: Constructive elements, mortar for construction, ecology, recycled plastics, social housing

Surface effects on the elastic modulus of nanoporous materials (2009)

The mechanical properties of a nanoporous material depend not only on its porosity but also on its characteristic sizes of microstructure, e.g., the average sizes of ligaments. Classical continuum mechanics models cannot interpret this type of size dependence. We here present a unit-cell micromechanics model to predict the effective Young’s modulus of open-cell nanoporous materials. The theory of surface elasticity is adopted to incorporate the effects of surface energy and residual surface stress on the effective elastic property of nanoporous materials. This model can reasonably elucidate the relevant experimental results.
Synthesis, Microstructure, and Catalytic Performance of Monolithic Low‐Density Porous Au (2017)

A series of monolithic porous Au with different pore sizes are successfully synthesized by a facile template‐dealloying corrosion method. Spherical Cu particles are employed as sacrificial templates, and a FeCl 3 –HNO 3 two‐step corrosion method is developed to dissolve the Cu components. The microstructure and phase evolution, as well as the effect of the corrosive media, are investigated in this study. As a result, the prepared monolithic porous Au possesses ultra‐low density and a special hollow porous core‐shell structure. When a small‐sized template (≈1 μm) is adopted, the corresponding density is as low as 0.37 g cm −3 (1.8% of the full density of Au). In addition, due to the special structure, the monolithic porous Au exhibits good catalytic performance (K app = 0.43 min −1 ), that is, relatively higher than that of most traditional Au‐based powder/slurry materials.
Endothelial dysfunction and exercise performance in lone atrial fibrillation or associated with hypertension or diabetes: different results with cardioversion (2006)

Endothelial dysfunction and underperfusion of exercising muscle contribute to exercise intolerance, hyperventilation, and breathlessness in atrial fibrillation (AF). Cardioversion (CV) improves endothelial function and exercise performance. We examined whether CV is equally beneficial in diabetes and hypertension, diseases that cause endothelial dysfunction and are often associated with AF. Cardiopulmonary exercise and pulmonary and endothelial (brachial artery flow-mediated dilation) function were tested before and after CV in patients with AF alone (n = 18, group 1) or AF with hypertension (n = 19, group 2) or diabetes (n = 19, group 3). Compared with group 1, peak exercise workload, O2 consumption (Vo2), O2 pulse, aerobic efficiency (Delta Vo2/Delta WR), and ratio of brachial diameter changes to flow changes (Delta D/Delta F) were reduced in group 2 and, to a greater extent, in group 3; exercise ventilation efficiency (Ve/Vco2 slope) and dead space-to-tidal volume ratio (Vd/Vt) were similar among groups. CV had less effect on peak workload (+7% vs. +18%), peak Vo2 (+12% vs. +17%), O2 pulse (+33% vs. +50%), Delta Vo2/Delta WR (+7% vs. +12%), Ve/Vco2 slope (-6% vs. -12%), Delta D/Delta F (+7% vs. +10%), and breathlessness (Borg scale) in group 2 than in group 1 and was ineffective in group 3. The antioxidant vitamin C, tested in eight additional patients in each cohort, improved flow-mediated dilation in groups 1 and 2 before, but not after, CV and was ineffective in group 3, suggesting that the oxidative injury is least in lone AF, greater in hypertension with AF, and greater still in diabetes with AF. Comorbidities that impair endothelial activity worsen endothelial dysfunction and exercise intolerance in AF. The advantages of CV appear to be inversely related to the extent of the underlying oxidative injury.
The use of computerized business games to simulate business behavior under different policies (1979)

Computerized business games can be used as a research tool to investigate in a laboratory setting how business firms respond to either governmental policies or to policies established by corporate headquarters. This idea was tested by comparing performance in 2 industries which had constraints placed on certain decision variables to that in 2 industries without constraints on these variables.
Method of metadata synchronization in parallel distributed databases (2011)

Metadata in a parallel distributed database contains information about table fragmentation, physical storage distribution, and access control policies. It is essential to query processing and security policy enforcement. Metadata in a parallel distributed database is usually stored in the form of system tables, it can be replicated through out every site in the system in order to improve performance and availability. Changes to the metadata should be aware by every site with acceptable delay and consistency. In this paper, a novel method is proposed to deal with the problem of metadata synchronization in parallel distributed databases. A locking mechanism is devised to coordinate different database operations, it can postpone data moving operations and carries out propagation only when necessary. Compared with existing methods, it dramatically reduces the communication between different sites, such that situations can be avoided in which all sites require updates simultaneously and a large portion of network bandwidth is consumed at a burst. Experiment results show the superiority of the proposed method over the others.
REDUCING POWER PEAKS AND ENERGY CONSUMPTION IN RAIL TRANSIT SYSTEMS BY SIMULTANEOUS TRAIN RUNNING TIME CONTROL (2004)

This paper presents a new approach to train running time control in order to achieve energy cost reductions. Given an optimal combination of headways and synchronization time, it is sufficient to apply a controller based on the minimization of a single train's energy using dynamic Programming. When these conditions can not be met, the modification of train running times can contribute to significantly reducing power peaks and energy consumption and thereby reducing energy costs in rail transit systems.
Immunization with immune complex alters the repertoire of antigen‐reactive B cells in the germinal centers (1997)

The differentiation of memory B cells in germinal centers (GC) is selectively enhanced upon administration of antigen-antibody complexes. To characterize the repertoire of this response, we examined the rearranged immunoglobulin heavy chain variable (V(H)) genes from mouse splenic GC after a single immunization with either antigen, nitrophenyl (NP) hapten coupled to keyhole limpet hemocyanin, or with a preformed complex of antigen with a monoclonal anti-NP antibody of gamma1 isotype. Among antigen-immunized mice, NP-reactive GC B cell populations in the antigen-induced GC consisted mostly of cells expressing the canonical V186.2 gene which contained, on average, 0.8 point mutations/V(H) gene by day 8 after immunization. These results are indicative of the beginning of somatic hypermutation and consistent with previously published analyses of NP antigen-driven GC. In contrast, the NP-specific B cells in GC that were elicited by administration of immune complex represented a heterogeneous cell population expressing nine different germ-line segments of the V186.2/V3 (J558) gene family, i.e. V23, V24.8, C1H4, V3, CH10, V165.1, V102, V671.5 and V186.2. Moreover, the average frequency of mutations in these genes was 1.7, reaching up to 4 mutations/V(H) in some GC. Administration of the antigen NP in complex with specific antibody apparently alters the process of interclonal competition in the GC and results in loss of dominance by V186.2+ cells and nearly stochastic representation of diverse clonotypes. These results suggest an important feedback regulation of the B cell repertoire by antibody and indicate a role for immune complexes in the activation of somatic hypermutation.
Fundamentals for Consistent Event Ordering in Distributed Shared Memory Systems (2005)

A large number of tasks in distributed systems can be traced down to the fundamental problem of attaining a consistent global view on a distributed computation. This problem has been addressed by a number of studies which focus on systems with message passing as their only means of interprocess communication. In the paper at hand we extend this restricted system model by additionally accounting for an abstract memory to be shared by the processes. We specify necessary and sufficient conditions for constructing a consistent global view on such systems and present helpful definitions, which are meant to be a solid formal base for further studies.
61‐1: <i>Invited Paper</i> : Light‐field Display Architecture and the Challenge of Synthetic Light‐field Radiance Image Rendering (2017)

The ability to render 3D data/scenes onto 2D displays have greatly enhanced the human ability to visualize complex scenes. However, when 3D information is projected in 2D, many of the natural depth cues are lost or are incorrect requiring a higher cognitive effort from the viewer to reconstruct the scene. A light‐field display projects perspective correct, full parallax 3D aerial imagery independent of the number of viewers or viewer positions. As such, light‐field displays enable collaboration and promote the analysis of complex information; however, the generation of the synthetic light‐field is computationally challenging with off‐the‐shelf GPUs. Light‐field projection fidelity aside, the high Size, Weight and Power (SWaP) cost of light‐field rendering ultimately limits the deployment of light‐field display systems. This is partly due to the issue that the modern GPUs and rendering APIs do not support multi‐view rendering natively.
Cerebral energy metabolism, glucose transport and blood flow: changes with maturation and adaptation to hypoglycaemia. (1997)

Brain maturation is characterized by a peak of cerebral energy metabolism and blood flow occurring between 3 and 8 years of age in humans and around 14-17 days of postnatal life in rats. This high activity coincides with the period of active brain growth. The human brain is dependent on glucose alone during that period, whereas rat brain uses both glucose and ketone bodies to cover its energetic and biosynthetic needs. The maturation of the density of glucose transporter sites-GLUT1 located at the blood-brain barrier and GLUT3 at the neuronal membrane-parallels the development of cerebral glucose utilization. During moderate acute hypoglycaemia, there are no changes in cerebral functional activity; cerebral glucose utilization decreases and blood flow increases only when hypoglycaemia is severe (lower than 2 mumol/ml). During chronic hypoglycaemia, the brain adapts to the low circulating levels of glucose: the number of glucose transporter sites is increased, and cerebral glucose utilization and function are maintained at normal levels while cerebral blood flow is more moderately increased than during acute hypoglycaemia. Neuronal damage consecutive to severe and prolonged hypoglycaemia occurs mainly in the cerebral cortex, hippocampus and caudate-putamen as a result of active release of excitatory amino acids.
Integration of rain water harvesting and drip irrigation for increasing productivity of lemon [Citrus limon (L.) Burmf) (2012)

An experiment on integration of rainwater harvesting with drip irrigation to increase productivity of lemon was conducted at Assam Agricultural University, Jorhat, Assam during 2009 to 2011. Rainwater harvested in plastic film lined pond during Kharif season was utilized to irrigate plants of lemon grown at 3 m x 3m spacing using drip irrigation with three levels during Rabi. Black plastic mulch was used as an additional water saving technique. The irrigation levels tested were 1.0, 0.8 and 0.6 times of pan evaporation (PE) measured by a USDA Class-A pan. Two years old lemon plants were subjected to the treatments for three consecutive years. The harvested water was monitored for yield and quality. Crop yield and quality, water use and economic analysis were carried out. The analysis of year wise as well as pooled data on plant height, canopy diameter, stem girth, and yield in terms of number of fruits per plant revealed that only drip irrigation irrespective of different levels significantly influenced the observed parameters. Black plastic did not significantly influence growth and yield of lemon. The economic analysis revealed that the integration of rainwater harvesting and drip irrigation was a viable option for increasing productivity and quality of lemon fruits at BCR (benefit to cost ratio) of 2.33.
