Perturbation theory vs. simulation for tadpole improvement factors in pure gauge theories

We calculate the mean link in Landau gauge for Wilson and improved SU(3) anisotropic gauge actions, using two loop perturbation theory and Monte Carlo simulation employing an accelerated Langevin algorithm. Twisted boundary conditions are employed, with a twist in all four lattice directions considerably improving the (Fourier accelerated) convergence to an improved lattice Landau gauge. Two loop perturbation theory is seen to predict the mean link extremely well even into the region of commonly simulated gauge couplings and so can be used remove the need for numerical tuning of self-consistent tadpole improvement factors. A three loop perturbative coefficient is inferred from the simulations and is found to be small. We show that finite size effects are small and argue likewise for (lattice) Gribov copies and double Dirac sheets.Comment: 13 pages of revtex

Enhancement of the Conventional Sri Lankan National Fuel Pass to a Comprehensive Fuel Station Application

Due to the economic crisis in Sri Lanka. There was a fuel supply problem because of the lack of foreign currency. Even though the government tried to supply the fuel demand, it was unsuccessful due to refueling the fuel since all people were trying full tank their vehicles. Therefore, the government took a new approach by creating a simple QR code scanning application. Even though the application was developed, the features were minimal. To give good insight and emotions to the users, improve their user experience, and maximize user usability Fuel Station App was developed. This is capable of viewing, Downloading, Regenerating the QR, Managing and altering the user profiles, and calculating the fuel consumption of the user vehicle. After the development phase, the app was tested, and the results were collected from the study. The survey confirmed that the users prefer the proposed solution to pump fuel and get good insights from the application

Characterization of anti-crotalic antibodies

AbstractCrotalus durissus terrificus, C. d. collilineatus, C. d. cascavella and C. d. marajoensis are responsible minor but severe snake bites in Brazil. The venoms of these snakes share the presence of crotoxin, a neurotoxin comprising of two associated components, crotapotin and phospholipase A2 (PLA2). Treatment of the victims with specific antiserum is the unique effective therapeutic measure. The ability of anti-Crotalus antisera produced by the routine using crude venom to immunize horses or purified crotoxin and PLA2 as individual immunogens was compared. Antisera obtained from horses immunized with C. durissus terrificus crude venom were able to recognize and neutralize not only the toxins presents in C. durissus terrificus, but also the ones present in the venoms from C. d. collilineatus, C. d. cascavella and C. d. marajoensis. Antisera from horses immunized with individual crotoxin or PLA2, although in lesser titers, were also able of recognizing the toxins in all four Crotalus species and neutralize the lethality of the C. d. terrificus venom

Composição E Diversidade De Anuros Na Restinga Do Município De Conde, Litoral Norte Do Estado Da Bahia, Nordeste Do Brasil

The Conde municipality is located in the northern coast of the state of Bahia (NC), northeastern Brazil, and is part of the Atlantic Tropical domain. The anuran fauna of the northern portion of the NC is still poorly known if compared to the southern portion. The Restinga is one of the predominant environments of the coastal plains of the NC and it is characterized essentially by presenting sandy soil covered by herbaceous and shrubby vegetation. The objective of this study was to determine the anuran species composition and diversity for the Restinga of the Conde municipality. Sampling was carried out at night by active search over four periods of five consecutive days each, two over the ‘main rainy season’ and two in a ‘lesser rainy season’, using 14 sample units (SUs) and five extra sample plots (EPs). We calculated dominance and species diversity using the Berger-Parker and Shannon-Wiener H’ indices, respectively. We used accumulation curves and the Jackknife 1 estimator to estimate anuran species richness, considering only the data obtained from the SUs. We recorded 713 anuran specimens distributed within 33 species, 13 genera and five families (Bufonidae, Craugastoridae, Hylidae, Leptodactylidae and Microhylidae). The Hylidae and Leptodactylidae families had the highest species richness. Considering only the SUs (Jackknife 1 estimator in brackets), we recorded 28 species in the study area (33.9 ± 2.3), 13 in Shrubby Vegetation Zones-SVZ (20.8 ± 2.9) and 25 in Freshwater Wetland Zones-FWZ (28.9 ± 1.9). The abundance and species diversity of the FWZ (n = 638 specimens; H’= 2.4) were higher than those recorded for the SVZ (n = 52 specimens; H’ = 1.9). The SVZ and FWZ showed distinct dominant species, wherein Pristimantis paulodutrai was the dominant species in SVZ and Scinax fuscomarginatus in FWZ. The Restinga of the Conde municipality stands out as the one with the highest anuran species richness already recorded considering only SVZ and FWZ. Moreover, its anuran species composition represented 55% of the anuran species known for the NC and included taxa common to three different morphoclimatic domains (Tropical Atlantic, Cerrado and Caatinga). © 2016, Universidade Estadual de Campinas UNICAMP.

Uso Do 1-mcp E Atmosfera Modificada Na Pós-colheita De Atemoia 'gefner'

The scarcity of technologies related to the post-harvest physiology of this species is one of the barriers to commercialization of atemoya over long distances, aggravated by perishability presented by them. Thus, the objective of this study was to prolong the shelf life of atemoya fruits using 1-methylcyclopropene (1-MCP) and modified atmosphere by low-density polyethylene (LDP), associated with refrigeration. The experiment was conducted in a completely randomized design in a split-plot, with plots in the four doses of 1-MCP (0, 200, 400 and 600 ?L L-1), and in the 5 subplots evaluation periods after harvest in the range of 5 days, with four replicate. Atemoyas were harvested at physiological maturity then treated with doses of 1-MCP for 8 h at room temperature. Soon after, the fruits were placed in polystyrene trays. Some remained unpacked and others were packed with a plastic film of LDP 16 μm. The use of modified atmosphere and 1-MCP alone or combined, were effective in delaying the ripening of fruits, allowing the preservation of its chemistry quality. In the fruits treated with 1-MCP was no delay in the accumulation of soluble solids and starch degradation.112677

Anadenanthera colubrina vell brenan : anti-candida and antibiofilm activities, toxicity and therapeutical action

We evaluated the antifungal and antibiofilm potential of the hydroalcoholic extract of bark from Anadenanthera colubrina (vell.) Brenan, known as Angico, against Candida spp. Antifungal activity was evaluated using the microdilution technique through the Minimum Inhibitory and Fungicide Concentrations (MIC and MFC). The antibiofilm potential was tested in mature biofilms formed by Candida species and analyzed through the counting of CFU/mL and scanning electron micrograph (SEM). In vivo toxicity and therapeutic action was evaluated in the Galleria mellonella model. The treatment with the extract, in low doses, was able to reduce the growth of planktonic cells of Candida species. MIC values range between 19.5 and 39 µg/mL and MFC values range between 79 and 625 µg/mL. In addition was able to reduce the number of CFU/mL in biofilms and to cause structural alteration and cellular destruction, observed via SEM. A. colubrina showed low toxicity in the in vivo assay, having not affected the viability of the larvae at doses below 100mg/kg and high potential in the treatment of C. albicans infection. Considering its high antifungal potential, its low toxicity and potential to treatment of infections in in vivo model, A. colubrina extract is a strong candidate for development of a new agent for the treatment of oral candidiasis33CONSELHO NACIONAL DE DESENVOLVIMENTO CIENTÍFICO E TECNOLÓGICO - CNPQ552562/2011-

Hypothalamic Endoplasmic Reticulum Stress Of Overtrained Mice After Recovery

knowing the relationship between endoplasmic reticulum (ER) stress and inflammation and based on the fact that downhill running-based overtraining (OT) model increases hypothalamus levels of some pro-inflammatory cytokines, we verified the effects of three OT protocols on the levels of BiP, pIRE-1 (Ser734), pPERK (Thr981), pelF2alpha (Ser52), ATF-6 and GRP-94 proteins in the mouse hypothalamus after two weeks of recovery. Methods: the mice were randomized into control (CT), overtrained by downhill running (OTR/down), overtrained by uphill running (OTR/up) and overtrained by running without inclination (OTR) groups. After 2-week total recovery period (i.e., week 10), hypothalamus was removed and used for immunoblotting. Results: The OTR/down group exhibited high levels of BiP and ATF6. The other OT protocols showed higher levels of pPERK (Th981) and pelf-2alpha (Ser52) when compared with the CT group. Conclusion: The current results suggest that after a 2-week total recovery period, the overtrained groups increased partially their ER stress protein levels, but without hypothalamic inflammation, which characterizes a physiological condition related to an adaptation mechanism.2

The Use Of Corticosteroid For The Prophylaxis Of Fat Embolism Syndrome In Patients With Long Bone Fracture [uso De Corticoide Na Profilaxia Para Síndrome De Embolia Gordurosa Em Pacientes Com Fratura De Osso Longo]

The "Evidence-based Telemedicine - Trauma & Acute Care Surgery" (EBT-TACS) Journal Club conducted a critical review of the literature and selected three recent studies on the use of corticosteroids for the prophylaxis of fat embolism syndrome (FES). The review focused on the potential role of corticosteroids administration to patients admitted to the intensive care unit (ICU) at risk of developing post-traumatic fat embolism. The first study was prospective and aimed at identifying reliable predictors, which could be detected early and were associated with the onset of fat embolism syndrome in trauma patients. The second manuscript was a literature review on the role of corticosteroids as a prophylactic measure for FES. The last manuscript was a meta-analysis on the potential for corticosteroids to prophylactically reduce the risk of fat embolism syndrome in patients with long bone fractures. The main conclusions and recommendations reached were that traumatized patients should be monitored with non-invasive pulse oximetry and lactate levels since these commonly-available tests may predict the development of FES, and the lack of evidence to recommend the use of steroids for the prophylaxis of this syndrome.405423426Gopinathan, N.R., Sen, R.K., Viswanathan, V.K., Aggarwal, A., Mallikarjun, H.C., Rajaram Manoharan, S.R., Early, reliable, utilitarian predictive factors for fat embolism syndrome in polytrauma patients (2013) Indian J Crit Care Med., 17 (1), pp. 38-42Sen, R.K., Tripathy, S.K., Krishnan, V., Role of corticosteroid as a prophylactic measure in fat embolism syndrome: A literature review (2012) Musculoskelet Surg., 96 (1), pp. 1-8Bederman, S.S., Bhandari, M., McKee, M.D., Schemitsch, E.H., Do corticosteroids reduce the risk of fat embolism syndrome in patients with long-bone fractures?
