Negotiating the ‘plastic rocket’: masculinity, car styling and performance in the Swedish modified car community

This article adds new knowledge on the ways that car modifiers negotiate their cars in relation to design, power and performance as qualities that make cars attractive. In order to understand the complex ways in which masculinity and cars co-constitute masculine subjectivities and communities, the article uses the modifier-car as a tool to discuss how certain ways of modifying and personifying cars create links between masculinity and cars at risk in male-dominated communities. Despite the fact that modified cars may share the looks and sounds of typical racing cars – and therefore appear to encompass some of the most convincing elements of power in automobile systems, namely the capacity for risk-taking – it is rather an alleged lack of power ascribed to some versions of modified cars – the plastic rocket – that stand out as a risk to constructions of modifier masculinity. Viewed as a feminized car, the plastic rocket has come to be negotiated as an inauthentic, foreign, powerless and vulgar example of modifying cars compared to the Swedish modified car community's working-class self-image. At the very core of the plastic rocket is a threat to modifier masculinity which is the inability to back up one's looks with strength. It is argued that the discourses formed around the plastic rocket indicate ‘queer’ possibilities in the ways cars extend male bodies.
Excitation of EMIC waves detected by the Van Allen Probes on 28 April 2013

We report the wave observations, associated plasma measurements, and linear theory testing of electromagnetic ion cyclotron (EMIC) waves observed by the Van Allen Probes on 28 April 2013. The waves are detected in their generation regions as three individual events in the two consecutive orbits of the Van Allen Probes-A, but the other spacecraft, B, does not detect any significant EMIC wave activity during the period. Present are three overlapping H+ populations around the plasmapause during the waves. It is found that the difference between the observational EMIC wave growth parameter (Σh) and the theoretical EMIC instability threshold (Sh) is significantly raised, on average, to 0.32±0.03, 0.43±0.02, and 0.32±0.02 during the three waves, respectively. Compared to linear theory (Σh > Sh), they are elevated thresholds for EMIC wave excitation.
Novel Plant Immune-Priming Compounds Identified via High-Throughput Chemical Screening Target Salicylic Acid Glucosyltransferases in Arabidopsis[W][OA]

This study used high-throughput screening to identify five immune priming chemicals that potentiate but do not directly induce defense responses. These compounds inhibit salicylic acid (SA) glucosyltransferases and increase SA during pathogen infection. Thus, SA glucosylation can be a target for developing novel crop protectants. Plant activators are compounds, such as analogs of the defense hormone salicylic acid (SA), that protect plants from pathogens by activating the plant immune system. Although some plant activators have been widely used in agriculture, the molecular mechanisms of immune induction are largely unknown. Using a newly established high-throughput screening procedure that screens for compounds that specifically potentiate pathogen-activated cell death in Arabidopsis thaliana cultured suspension cells, we identified five compounds that prime the immune response. These compounds enhanced disease resistance against pathogenic Pseudomonas bacteria in Arabidopsis plants. Pretreatments increased the accumulation of endogenous SA, but reduced its metabolite, SA-O-β-d-glucoside. Inducing compounds inhibited two SA glucosyltransferases (SAGTs) in vitro. Double knockout plants that lack both SAGTs consistently exhibited enhanced disease resistance. Our results demonstrate that manipulation of the active free SA pool via SA-inactivating enzymes can be a useful strategy for fortifying plant disease resistance and may identify useful crop protectants.
Reduced complexity iterative decoding of low-density parity check codes based on belief propagation

Two simplified versions of the belief propagation algorithm for fast iterative decoding of low-density parity check codes on the additive white Gaussian noise channel are proposed. Both versions are implemented with real additions only, which greatly simplifies the decoding complexity of belief propagation in which products of probabilities have to be computed. Also, these two algorithms do not require any knowledge about the channel characteristics. Both algorithms yield a good performance-complexity trade-off and can be efficiently implemented in software as well as in hardware, with possibly quantized received values.
Effects of the noise type on listening effort : relationship between subjective ratings and objective measurements

The present study investigates the relationship between the self-rated effort when listening to speech in adverse conditions, and response time, taken as a measure of the cognitive resources deployed for interpreting and responding to the auditory stimulus. Specifically, the peculiar effects of two background noises are assessed: a steady state, speech-shaped noise (SSN) and a fluctuating (ICRA) masker. Matrixed-word listening tests were proposed to a panel of young adults with normal hearing. Twelve realistic acoustic conditions were created by varying speech and noise levels, reverberation and noise type. For each condition intelligibility scores (IS), response time (RT) and self-rating of listening effort were collected. The results were mapped by using the objective short-term metric STIr, whose run-time nature allows the tracking of non-stationary maskers, properly accounting for “listening in the gaps”. Even though the same accuracy was achieved in the two maskers, the conditions with ICRA noise were always rated as more effortful; similarly, RT was significantly higher in fluctuating noise, revealing a greater engagement of cognitive resources.
Nitric oxide, oxidants, and protein tyrosine nitration

The occurrence of protein tyrosine nitration under disease conditions is now firmly established and represents a shift from the signal transducing physiological actions of •NO to oxidative and potentially pathogenic pathways. Tyrosine nitration is mediated by reactive nitrogen species such as peroxynitrite anion (ONOO–) and nitrogen dioxide (•NO2), formed as secondary products of •NO metabolism in the presence of oxidants including superoxide radicals (\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \setlength{\oddsidemargin}{-69pt} \begin{document} \begin{equation*}{\mathrm{O}}_{2}^{{\bullet}-}\end{equation*}\end{document}), hydrogen peroxide (H2O2), and transition metal centers. The precise interplay between •NO and oxidants and the identification of the proximal intermediate(s) responsible for nitration in vivo have been under controversy. Despite the capacity of peroxynitrite to mediate tyrosine nitration in vitro, its role on nitration in vivo has been questioned, and alternative pathways, including the nitrite/H2O2/hemeperoxidase and transition metal-dependent mechanisms, have been proposed. A balanced analysis of existing evidence indicates that (i) different nitration pathways can contribute to tyrosine nitration in vivo, and (ii) most, if not all, nitration pathways involve free radical biochemistry with carbonate radicals (\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \setlength{\oddsidemargin}{-69pt} \begin{document} \begin{equation*}{\mathrm{CO}}_{3}^{{\bullet}-}\end{equation*}\end{document}) and/or oxo–metal complexes oxidizing tyrosine to tyrosyl radical followed by the diffusion-controlled reaction with •NO2 to yield 3-nitrotyrosine. Although protein tyrosine nitration is a low-yield process in vivo, 3-nitrotyrosine has been revealed as a relevant biomarker of •NO-dependent oxidative stress; additionally, site-specific nitration focused on particular protein tyrosines may result in modification of function and promote a biological effect. Tissue distribution and quantitation of protein 3-nitrotyrosine, recognition of the predominant nitration pathways and individual identification of nitrated proteins in disease states open new avenues for the understanding and treatment of human pathologies.
SOMATOTIPO E COMPOSIÇÃO CORPORAL DE ATLETAS FEMININO DE PÓLO AQUÁTICO DO BRASIL

Long lasting exertion induced stress can alter body homeostasis that can remain visible during several days and seem to be This study aim was to compare the somatotype of water pole Athletes according to their game position and final classification in the 2005 Brazilian Championship. Fifty athletes were evaluated and their somatotype was calculated through the anthropometric method. Both the descriptive analysis and the comparison between the groups were made through the t-test and the variance analysis for repeated measures (ANOVA), followed by Bonferroni’s Post Hoc test (p < 0.05). The mean value of relative fat was of 22.9 ± 4.5%, thin body mass of 47.0 ± 4.1 kg, body mass 61.2 ± 6.1 kg. The mean somatotype values were 4.9-3.5-2.3 (endomorphic – mesomorphic). The Elite group had higher somatotype and body fat mass scores than the other athletes who were evaluated. When separated by their game position, the goal keeper athletes presented higher thin body mass scores than the athletes who were in other positions. We concluded that there are no significant differences in the mean somatotype between the athletes neither based on their final classification, nor due to the position in the game.
Depletion of Alveolar Macrophages Abrogates Prolongation of Cardiac Allograft Survival Induced by Intratracheal Delivery of Alloantigen

Background. We previously showed that pretreatment with intratracheal delivery (ITD) of alloantigen induced prolonged cardiac allograft survival and generated regulatory cells in mice. In this study, we examined the role of alveolar macrophages (AM) in our ITD model. Methods. Some CBA mice were given ITD of C57BL/6 splenocytes and underwent transplantation of C57BL/6 hearts 7 days later. In others, AM were depleted with clodronate-loaded liposomes 3 days before ITD. In adoptive transfer studies, whole splenocytes were obtained from ITD-treated CBA mice and administered to naïve CBA secondary recipients, which were given C57BL/6 hearts immediately afterward. Interleukin-10 concentrations in bronchoalveolar lavage fluid were assessed by enzyme-linked immunosorbent assays. Immunohistologic and flow cytometric studies were performed after ITD. Results. C57BL/6 splenocytes given by ITD were ingested by AM in 2 days and undetectable in paratracheal lymph nodes or spleen tissue. CBA mice given ITD of C57BL/6 splenocytes had markedly prolonged allograft survival (median survival time [MST], 86 days), whereas naïve CBA mice rejected allografts acutely (MST, 8 days). AM-depleted, ITD-treated mice also rejected allografts (MST, 5.5 days). Naïve secondary recipients given adoptive transfer of splenocytes from ITD-treated mice had prolonged allograft survival (MST, >100 days), whereas secondary recipients given adoptive transfer of splenocytes from AM-depleted, ITD-treated mice rejected the grafts (MST, 15.5 days). Interleukin-10 expression in bronchoalveolar lavage fluid was down-regulated in AM-depleted mice compared with naïve mice. Conclusions. AM have an important role in the induction of regulatory cells in our model of ITD of alloantigen.
Pretreated Butterfly Wings for Tuning the Selective Vapor Sensing

Photonic nanoarchitectures occurring in the scales of Blue butterflies are responsible for their vivid blue wing coloration. These nanoarchitectures are quasi-ordered nanocomposites which are constituted from a chitin matrix with embedded air holes. Therefore, they can act as chemically selective sensors due to their color changes when mixing volatile vapors in the surrounding atmosphere which condensate into the nanoarchitecture through capillary condensation. Using a home-built vapor-mixing setup, the spectral changes caused by the different air + vapor mixtures were efficiently characterized. It was found that the spectral shift is vapor-specific and proportional with the vapor concentration. We showed that the conformal modification of the scale surface by atomic layer deposition and by ethanol pretreatment can significantly alter the optical response and chemical selectivity, which points the way to the efficient production of sensor arrays based on the knowledge obtained through the investigation of modified butterfly wings.
Enrollment and participation in a pilot walking programme: The role of self-efficacy

This pilot study investigated the association of self-efficacy with enrollment in and compliance with an 8-week exercise trial. We compared self-efficacy levels of adults who were eligible but did not enroll (N=221) to those who enrolled (N=115) and enrollees who were compliant at the end of the study (N=66). Those in the top three self-efficacy quintiles had higher odds of enrollment (adjusted odds ratios (AOR)=2.61–2.82) and being compliant at the end of the trial (AOR=4.31–4.38) compared to those in the lowest efficacy quintile. These results demonstrated the theoretical association between self-efficacy and one’s choice of behavior.
Dynamics of Appearance and Expansion of a Prolyliminopeptidase- Negative Subtype among Neisseria gonorrhoeae Isolates Collected in Sydney, Australia, from 2002 to 2005

ABSTRACT Recent studies have demonstrated a wide geographic circulation of isolates of Neisseria gonorrhoeae that fail to produce prolyliminopeptidase (PIP). Tests based on the production of this enzyme are important elements of a number of identification systems for gonococci. We documented the appearance, expansion, and contraction of subtypes of 165 PIP-negative gonococci detected in an extended and systematic sample of the 3,926 N. gonorrhoeae isolates collected in Sydney, Australia, from July 2002 to September 2005. Their appearance, peak, and decline followed an “epidemic” curve. At the peak of their prevalence in 2003, PIP-negative gonococci comprised 22% of all isolates. Closely related phenotypes accounted for 162/165 of the PIP-negative gonococci. Algorithms for confirmation of N. gonorrhoeae should take account of the temporal and geographic variability of gonococci by utilizing two or more distinct confirmatory methods.
Ear Acupressure, Heart Rate, and Heart Rate Variability in Patients with Insomnia

This high-tech “teleacupuncture study” describes a neurovegetative ear acupressure effect in patients with chronic insomnia by using heart rate variability analysis. Heart rate (HR) and heart rate variability (HRV) measurements in 31 patients (mean age ± SD: 54.3 ± 10.6 years) were performed under standardized conditions in Harbin, China, and the data analysis was performed in Graz, Austria. Similar to our previous clinical and basic teleacupuncture research works, the electrocardiograms (ECGs) were recorded by an HRV Medilog AR12 system during ear acupressure of the Shenmen point on the left ear. HR decreased significantly (P < 0.05) during and after acupressure stimulation. The effect was not visible after the first stimulation, rather it appeared in the phase following the second acupressure stimulation (10 min after the first stimulation). Total HRV showed significant stimulation-dependent increases (P < 0.05), immediately after each acupressure stimulation with a maximum after the third stimulation (20 min after the first stimulation), but there was no long-lasting effect. The present results can serve as a solid basis for the further investigations of auricular point stimulation for noninvasive complementary use in treating insomnia.
Will more higher education improve economic growth

Calls for expanded university education are frequently based on arguments that more graduates will lead to faster growth. Empirical analysis does not, however, support this general proposition. Differences in cognitive skills—the knowledge capital of countries—can explain most of the differences in growth rates across countries, but just adding more years of schooling without increasing cognitive skills historically has had little systematic influence on growth.

Vascular Endothelial Growth Factor Expression in Oral Epithelial Dysplasia and Oral Squamous Cell Carcinoma

Background: Among the molecular events involved in carcinogenesis, neovascularization or angiogenesis is considered to be crucial for tumor growth and progression. VEGF is an angiogenic cytokine involved in endothelial cell proliferation, migration and differentiation. Aim: The purpose of this study was to investigate the immunohistochemical expression of VEGF in normal oral mucosa (NOM), epithelial dysplasia and oral squamous cell carcinoma (OSCC) and to correlate this expression with histologic features of tumor progression. Materials and methods: In this retrospective study, we examined the immunohistochemical expression of VEGF in 46 oral mucosal biopsy samples which consisted of 5 normal oral mucosal specimens, 17 specimens with varying histologic degrees of epithelial dysplasia and 24 invasive OSCC specimens with varying grades of tumor differentiation. Results: Statistical analysis indicated an upregulation of VEGF during the transition from NOM through epithelial dysplasia to

The temperament and character inventory revised (TCI-R): descriptive and factor structure in different age levels

This study was aimed to evaluate the psychometric properties and the relationship of age with the answers, internal consistency and factorial structure of the TCI-R. The questionnaire was responded by a sample of 928 voluntary subjects (396 males and 532 women), with a mean age of 30 years old. The participants under 30 scored substantially higher in Novelty Seeking, and to a lesser extent in Reward Dependence, while aged subjects scored significant higher in Harm Avoidance, Self-Directiveness and Cooperation. The global coefficients of factorial congruence were higher than 0.90 in all age groups. The goodness-of-fit indexes in the CFA were unsatisfactory for the simple structure models, although improved when considering secondary loadings. Implications for further research with the TCI-R are discussed.
Dilated Cardiomyopathy with Increased SR Ca2+ Loading Preceded by a Hypercontractile State and Diastolic Failure in the α1CTG Mouse

Mice over-expressing the α1−subunit (pore) of the L-type Ca2+ channel (α1CTG) by 4months (mo) of age exhibit an enlarged heart, hypertrophied myocytes, increased Ca2+ current and Ca2+ transient amplitude, but a normal SR Ca2+ load. With advancing age (8–11 mo), some mice demonstrate advanced hypertrophy but are not in congestive heart failure (NFTG), while others evolve to frank dilated congestive heart failure (FTG). We demonstrate that older NFTG myocytes exhibit a hypercontractile state over a wide range of stimulation frequencies, but maintain a normal SR Ca2+ load compared to age matched non-transgenic (NTG) myocytes. However, at high stimulation rates (2–4 Hz) signs of diastolic contractile failure appear in NFTG cells. The evolution of frank congestive failure in FTG is accompanied by a further increase in heart mass and myocyte size, and phospholamban and ryanodine receptor protein levels and phosphorylation become reduced. In FTG, the SR Ca2+ load increases and Ca2+ release following excitation, increases further. An enhanced NCX function in FTG, as reflected by an accelerated relaxation of the caffeine-induced Ca2+ transient, is insufficient to maintain a normal diastolic Ca2+ during high rates of stimulation. Although a high SR Ca2+ release following excitation is maintained, the hypercontractile state is not maintained at high rates of stimulation, and signs of both systolic and diastolic contractile failure appear. Thus, the dilated cardiomyopathy that evolves in this mouse model exhibits signs of both systolic and diastolic failure, but not a deficient SR Ca2+ loading or release, as occurs in some other cardiomyopathic models.
Regeneration mode affects spatial genetic structure of Nothofagus dombeyi forests

Disturbance may generate population bottlenecks by reducing population size and the number of founders establishing a new colony. We tested the hypothesis that the scale of disturbance affects the levels of genetic diversity and the spatial distribution of genotypes in naturally regenerating stands of Nothofagus dombeyi, an evergreen angiosperm tree, in northwestern Patagonia. At similar spatial scales, we predicted that old‐growth stands characterized by fine‐scale gap phase dynamics would be genetically diverse due to restricted gene flow among temporal and spatially isolated gaps. In contrast, young massively regenerated postfire cohorts resulting from coarse‐scale disturbances would be genetically more homogeneous. At each of three paired old‐growth and postfire stands a minimum of 50 trees were mapped and sampled within 1 ha. Fresh tissue was collected for isozyme analysis from a total of 361 trees along with tree cores and diameters. Tree age distributions reflected the dominant modes of regeneration. Six out of nine analysed loci were polymorphic. Mean genetic diversity parameters were greater but not significant in mature stands. Fixation indices suggested significant heterozygous deficit at two‐thirds of possible tests indicating a Wahlund effect due to local recruitment of related seeds. FST indicated moderate between‐stand divergence. Mature stands concentrated half of positively like joins and yielded significant (P < 0.05) autocorrelation coefficients at small distance classes (< 20 m). Fine‐scale patch dynamics within mature stands favours the maintenance of fine‐scale genetic structure as a result of shade intolerance and local seed dispersal. Conversely, postfire stands suffer the effects of genetic drift given that a few reproductive trees produce a somewhat impoverished and genetically uniform progeny. Bottleneck effects will depend upon the density of remnant trees which could also be a function of the severity of fire.
