The practice of voting as intangible heritage: An exercise worth cultivating

A medida que el concepto de lo que constituye el patrimonio se ha ampliado desde el tangible, al natural y al patrimonio intangible, de los objetos y monumentos a las estructuras geologicas y formaciones a las practicas culturales, los academicos todavia mantienen un amplio debate en cuanto a que se considera patrimonio inmaterial, que es lo que se concibe como tal, que se debe valorar y promover. Es necesario ampliar el debate para definir que practicas culturales, mas alla del folclore, deben ser incluidos. Se necesita mas debate sobre la forma de definir que practicas culturales, deben ser incluidas bajo la categoria de patrimonio intangible, mientras que se delinean sus limites y principios que lo definen.En este articulo se presenta una breve revision sobre el movimiento internacional para preservar y promover el patrimonio inmaterial y se defiende que en la participacion politica, un elemento clave para la fortaleza y preservacion de nuestras sociedades democraticas es necesario tener en cuenta el patrimonio intangible, ya que es fundamental para mantener las estructuras democraticas existentes hoy en dia en todo el mundo. El articulo se centra en la afirmacion de la salvaguardia de los tipos convencionales de participacion politica, como ejercer el derecho al voto, lo cual en muchas sociedades occidentales ha sufrido una notable disminucion, especialmente entre los jovenes. Teniendo en cuenta evidencias empiricas se muestra una importante correlacion entre la formacion y el hecho de ejercer el derecho al voto y que esta es una practica que se crea con la practica.
R&D in the Public and Private Sector in Brazil: Complements or Substitutes?

The purpose of this paper is to analyse the evolution of the relations between the Brazilian public research sector, particularly the universities, and the productive sector as stimulated, directly or indirectly, by government policies from the 70's up to the present days. Special emphasis is given to the schemes devised by the Ministry of Science and Technology, which was created in 1985. The argument we want to develop is that government actions to bring universities and enterprises closer together may have succeeded in doing so for the duration of a specific project, but were unable to create long-lasting links. The role of university research as complementary to, and not substitute for, industrial research is emphasised in a number of recent studies on innovation, as outlined in the first section. Then, we proceed to the analysis of the evolution of the relations between the public sector research and industry in Brazil. We start with a sketch of the industrialisation by import substitution model adopted in Brazil, highlighting the role played in it by local R&D, when the country was under military rule. Next we tackle the changes in those relations as the country reoriented its development model with the return to democratic regime in 1985. The Ministry of Science and Technology, created in that year, has since then devised and implemented a number of schemes to foster links between public sector research and enterprises. The most significant of those schemes are presented and their results are analysed. We conclude by saying that government actions to stimulate private investment in R&D as well as fostering links between enterprises and public sector research had a very limited success
Microsatellite analysis at 10q25‐q26 in Sardinian patients with sporadic endometrial carcinoma

Loss of heterozygosity (LOH) at chromosome 10q25‐q26 has been reported previously in endometrial carcinoma (EC), suggesting the presence of tumor suppressor gene(s). Nevertheless, frequency of genome‐wide microsatellite instability (MSI) has been demonstrated higher in EC than in other common malignancy, mostly due to defective DNA mismatch repair. The authors further evaluated the role of the chromosome 10q25‐q26 in endometrial tumorigenesis as well as the clinical significance of any observed genetic alteration in sporadic EC.
A novel broken rotor bar fault detection method using park's transform and wavelet decomposition

Detection of broken rotor bars has been an important but difficult work in fault diagnosis area of induction motors. The characteristic frequency components of faulted rotor are very close to the power frequency component but by far less in amplitude, which brings about great difficulty for accurate detection. In the present study, a new method is proposed in order to remove the main frequency component, resulting in more efficient detection of the rotor fault characteristics in the frequency spectrum of stator currents. The method is based on Park's transformation in combination with discrete wavelet decomposition to eliminate the effect of main frequency and zoom on the energy of objective fault related frequency components. In addition, the method efficiency is evaluated using Simulations in Matlab.
The Fast and Winding Roads that Lead to The Doors: Generating Heterogeneous Music Playlists

Consider the problem of creating a wedding reception playlist. Such playlist should ideally satisfy a very diverse crowd by finding a perfect eclectic mix of songs to keep everyone satisfied. In fact, music playlists for large parties are usually composed by a very heterogeneous set of songs, so everyone can listen to songs of their liking at some point. Such playlists, which we call heterogeneous playlists, are also very appropriate in dynamic contexts, when the mood of the listener changes with time, such as workout sessions or road trips. The challenge of automatically generating heterogeneous playlists is to find the appropriate balance among several conflicting goals. For instance, the generated playlist should have smooth transitions between successive tracks while covering a highly diverse set of songs in the time the user has available to her/him. In this paper, we formulate the problem of automatically generating high quality heterogeneous playlists and propose two methods for solving it, namely ROPE and STRAW. We demonstrate the usefulness of our proposed algorithms by applying them to a large collection of songs. When compared with the state of the art algorithms, ROPE and STRAW are the only ones that can effectively satisfy all of the following quality constraints: heterogeneity, smooth transitions, novelty, scalability and usability.
Network Bridging Potential in Later Life

Objectives: Much work in social gerontology has examined older adults' social connectedness, but we know little about the extent to which older adults occupy positions of power and independence in their networks. The author uses health and life-course frameworks to understand older adults' prospects of occupying bridging positions between otherwise unconnected individuals. Methods: Egocentric social network data were collected from a nationally representative sample of 3,005 older adults between the ages of 57 and 85 in 2005-2006. A series of multivariate regression analyses was used to examine how health and life-course factors relate to bridging. Results: Age is not significantly associated with bridging. However, retirees and people with poor health are less likely to have bridging potential. At the same time, widows are more likely to serve as bridges. Discussion: The discusses the need for more dialogue between social network researchers and social gerontologists to help explain older adults' bridging prospects.
EER architecture specifications for OFDM transmitter using a class E amplifier

This letter presents envelope elimination and restoration (EER) architecture specifications in the case of orthogonal frequency division multiplex C band transmission. A key point is the recombination of envelope and phase information by supply modulation of the power amplifier (PA). Imperfections, such as time mismatch and phase noise can reduce the performances of the transmission. Compression and conversion effects when supply modulating the PA are introduced in this letter with the simulation of a class E power amplifier. This amplifier was designed under HP-ADS using a nonlinear MESFET model. Results are reported in terms of error vector measurement and spectrum for two different numbers of sub-carriers 32 and 128 in 16-QAM and 64-QAM cases.
Behaviour of the adrenergic cardiovascular drive in atrial fibrillation and cardiac arrhythmias.

AIM Animal studies have conclusively shown that the sympathetic nervous system plays a major role not only in regulating sinus node activity but also in promoting cardiac rhythm alterations. Less univocal and often circumstantial have been the evidences collected on this issue in humans. However, the introduction of the microneurographic technique in clinical research has allowed to gain new important insights on the role of neuroadrenergic factors in the pathophysiology of cardiac arrhythmias. METHODS The present paper will review the results of microneurographic studies performed by our group and others in the field of cardiac rhythm disturbances by addressing three specific issues. First it will examine the relationships between heart rate and muscle sympathetic neural outflow in a variety of cardiovascular diseases characterized by sympathetic activation. This will be followed by an analysis of the behaviour of the sympathetic nerve traffic responses to paroxysmal atrial fibrillation. Finally, the sympathetic adjustments to spontaneously occurring or artificially induced pre-mature ventricular contractions will be highlighted.
Comparative study of steady-state performance of LED drivers at different modulation techniques

The paper deals with current and light regulators for luminaries with Light Emitting Diodes. Several topologies of the regulators with typical control formula (buck, boost and buck-boost) and several control methods (pulse-width and frequency modulation) are analyzed from the point of view of their control performance. Special attention is paid to the non-linearity of the proposed solutions and their accuracy in practically available control platforms. The control solutions are analyzed analytically and through simulations as well as confirmed experimentally. The conclusions about the most prospective solution are made.
Real-Time Analysis of the Control Structure and Management Functions of a Hybrid Microgrid System

Due to their non-controllable nature renewable energy source's (RES) participation in the network operation is currently rather deficient. In this paper the microgrid concept is presented as an innovative solution to improve RES integration into the grid. In this study an example of a hybrid microgrid composed of RES generators and a programmable support device together with a centralized management system is considered. The microgrid can operate both in grid-connected mode and in islanded mode. Its control structure as well as its management functions to assure successful performances in both operation modes and in the transitions between them are analyzed in detail and tested in real-time conditions with a physical control device
Variable colonization by oral streptococci in molar fissures of monoinfected gnotobiotic rats

Germfree Sprague-Dawley rats, fed a high-sucrose diet, were monoinfected with strains of Streptococcus mitis, Streptococcus sanguis, and Streptococcus mutans. Viable cell recoveries from six molar teeth, considered to reflect mainly bacterial colonization of intact fissures, were in the order of 10(6), 10(7), and 10(8) CFU, respectively. Some of the implications of the variation of bacterial plaque-forming ability in the rat model are discussed.

Examples from Integrating Systems Research into Undergraduate Curriculum

In this paper we motivate and discuss the use of examples drawn from computer systems research for use in the classroom. We describe three case studies used in an advanced undergraduate course covering large software system design. The case studies document situations we have encountered while designing and implementing performance modeling infrastructure and benchmark applications for use in our research on parallel processor design. Two of the case studies cover debugging techniques and are available publicly. The third case study covers performance analysis using freely available tools. The goals of this work are to illustrate how classroom concepts are realized in computer systems, to provide examples of how performance analysis and tuning can be applied to complex real-world applications such as our C++ architectural simulator, to motivate the use of profiling tools in instruction, and to expose students to research topics and methodology.

Spread of H5N1 avian influenza virus: an ecological conundrum

The role of wild birds in the spread of influenza H5N1 virus remains speculative and the ecology of influenza A viruses in nature is largely unstudied. There is an urgent need for multidisciplinary studies to explore the ecology of avian influenza viruses in wild birds and the environment to support ecological interpretation of the source of disease outbreaks in poultry.
The N-Terminally Truncated p53 Isoform &Dgr;40p53 Influences Prognosis in Mucinous Ovarian Cancer

Objective The tumor suppressor p53 generates the N-terminally truncated isoforms &Dgr;40p53 and &Dgr;133p53 that possess the ability to modulate p53 function in vitro. The aim of the present study was to evaluate the clinical relevance of p53 isoforms in the main histological subtypes of ovarian cancer. Methods &Dgr;40p53, &Dgr;133p53, and full-length p53 (FLp53) expression was determined in 45 mucinous, 30 endometrioid, and 91 serous ovarian cancer specimens as well as 42 normal ovarian tissues using reverse transcriptase–quantitative polymerase chain reaction. In a subgroup of mucinous ovarian cancer cases, &Dgr;40p53 expression was examined using Western blot analysis. A functional yeast-based assay and subsequent sequencing were performed to analyze the p53 mutational status. Results In endometrioid cancer specimens, &Dgr;133p53 expression was significantly lower than in mucinous and serous cases (P = 0.016) or in normal tissues (P = 0.004). Mucinous cancer samples showed elevated &Dgr;40p53 expression as compared with normal ovarian tissues (P = 0.003). In addition, high &Dgr;40p53 expression constituted an independent prognostic marker for recurrence-free but not for overall survival in patients with mucinous ovarian cancer (hazard ratio, 0.267; 95% confidence interval, 0.094–0.756 [P = 0.013]; hazard ratio, 0.453, 95% confidence interval, 0.193–1.064 [P = 0.069]). Western blot analysis confirmed the presence of p53β and &Dgr;40p53&agr; in a subset of patients with mucinous ovarian cancer. Expression of p53 isoforms was not associated with p53 mutational status or clinicopathologic parameters. Conclusions We show that expression of p53 isoforms differs in histological subtypes, thus supporting the hypothesis that histological subtypes represent distinct disease entities. In addition, we provide first evidence for a favorable role of &Dgr;40p53 in patients with mucinous ovarian cancer.
Measuring the human retinal oxygenation response to a hyperoxic challenge using MRI: Eliminating blinking artifacts and demonstrating proof of concept

The retinal oxygenation response to a hyperoxic challenge measured using MRI appears to be an early and accurate marker of retinopathy risk in experimental models, with promising clinical potential. However, the application of this technique in humans is limited by blinking artifacts that can confound detection of subtle signal intensity changes. We asked subjects to refrain from blinking during a 12‐s fast low‐angle shot (FLASH) image, and to blink if needed during the following 3‐s rest period. This no‐blink blink cycle was repeated sequentially 20 times during either room‐air or 100% oxygen breathing. Significant change (P < 0.05) was detected for the first time from the resultant blinking‐artifact‐free images in the preretinal vitreous oxygen tension (upper limit of about 13 mm Hg (1.8 KPa, N = 3)) following a 10‐min hyperoxic inhalation challenge. These results provide the proof‐of‐concept data needed for future MRI evaluation of the retinal oxygenation response and human retinopathy, such as diabetic retinopathy.

Perinatal Transmission of Major, Minor, and Multiple Maternal Human Immunodeficiency Virus Type 1 Variants In Utero and Intrapartum

ABSTRACT Previous studies have provided conflicting data on the presence of selective pressures in the transmission of a homogeneous maternal viral subpopulation to the infant. Therefore, the purpose of this study was to definitively characterize the human immunodeficiency virus type 1 (HIV-1) quasispecies transmitted in utero and intrapartum. HIV-1 envelope gene diversity from peripheral blood mononuclear cells and plasma was measured during gestation and at delivery in mothers who did and did not transmit HIV perinatally by using a DNA heteroduplex mobility assay. Children were defined as infected in utero or intrapartum based on the timing of the first detection of HIV. Untreated transmitting mothers (n = 19) had significantly lower HIV-1 quasispecies diversity at delivery than untreated nontransmittting mothers (n = 18) (median Shannon entropy, 0.711 [0.642 to 0.816] versus 0.853 [0.762 to 0.925], P = 0.005). Eight mothers transmitted a single major env variant to their infants in utero, and one mother transmitted a single major env variant intrapartum. Four mothers transmitted multiple HIV-1 envvariants to their infants in utero, and two mothers transmitted multiple env variants intrapartum. The remaining six intrapartum- and two in utero-infected infants had a homogeneous HIV-1env quasispecies which did not comigrate with their mothers' bands at their first positive time point. In conclusion, in utero transmitters were more likely to transmit single or multiple major maternal viral variants. In contrast, intrapartum transmitters were more likely to transmit minor HIV-1 variants. These data indicate that different selective pressures, depending on the timing of transmission, may be involved in determining the pattern of maternal HIV-1 variant transmission.
Development of antibody-secreting cells and antigen-specific T cells in cervical lymph nodes after intranasal immunization

Intranasal (i.n.) immunization with bacterial protein antigens coupled to cholera toxin B subunit (CTB) effectively induces mucosal, especially salivary immunoglobulin A (IgA), and nonmucosal antibody responses in mice. To examine the regional distribution of antigen-specific B and T cells after i.n. immunization, antibody-secreting cells and antigen-responsive T cells in cervical lymph nodes (CLN) were compared with those found after intraoral or subcutaneous (in the neck) administration of the same antigen and with T cells found in mesenteric lymph nodes (MLN) and spleen after intragastric immunization. The i.n. immunization induced predominantly IgA antibody-secreting cells in salivary glands and IgA and IgG antibody-secreting cells in the superficial and central CLN; these responses were quantitatively enhanced if the antigen was coupled to CTB. Intraoral immunization also induced IgA and IgG antibody-secreting cells in the superficial and central CLN, but only if intact cholera toxin was included as an adjuvant. In contrast, subcutaneous (neck) immunization induced IgG antibody-secreting cells mainly in the draining facial lymph nodes. CLN cell populations resembled those of MLN, except that CLN lymphocytes had higher proportions of T cells and lower proportions of B cells and a slightly higher CD4+/CD8+ ratio among T cells than the MLN lymphocytes did. T cells that proliferated in response to antigen in vitro were found especially in central CLN 2 days after i.n. immunization and persisted for up to 6 months, whereas after intragastric immunization, responsive T cells were not found in the MLN for up to 14 days. After culture with antigen in vitro, T cells from the superficial CLN of i.n. immunized mice secreted both gamma interferon and interleukin-4. Therefore, after i.n. immunization, superficial and central CLN represent sites of regional lymphocyte development, and the central CLN in particular appear to be sites where memory T cells persist.
