Centris garleppi

description: Centris garleppi (Schrottky, 1913)
 Hemisia garleppi Schrottky, 1913: 708.
 Type data: This species was described based on a single female collected by Otto Garlepp in Apurímac, southern Peru. Garlepp (1864‑1959) was a German naturalist and, as well as his brother Gustav (1862‑1907), a professional collector that worked actively in South America. The holotype is currently housed at DZUP but according to Moure (1999) it belongs to the MZSP. The specimen has the following data label: Apurimac Peru [handwritten]\ [black‑rimmed] Hemisia garleppi Schrottky ♀ [handwritten] C.S. Schrottky det. 19 [printed] 12 [handwritten]\ recebido de J.F. Zikán Pe Moure 1942 [handwritten].
 Comments: This is a poorly known species recorded only in Peru. Considering the dark metasoma with terga 4 to 6 reddish brown, this species is probably related to C. caelebs Friese, 1899 which also has the same pattern of coloration.

description: The polymer relaxation dynamic of a sample, stretched up to the stress hardening regime, is measured, at room temperature, as a function of the strain $λ$ for a wide range of the strain rate $\dotγ$, by an original dielectric spectroscopy set up. The mechanical stress modies the shape of the dielectric spectra mainly because it affects the dominant polymer relaxation time $τ$, which depends on $λ$ and is a decreasing function of $\dotγ$. The fastest dynamics is not reached at yield but in the softening regime. The dynamics slows down during the hardening, with a progressive increase of $τ$. A small inuence of $\dotγ$ and $λ$ on the dielectric strength cannot be excluded.

description: Cavernous hemangioma is a benign tumor that may occur in any part of the body. Its occurrence in the testicular parenchyma is extremely rare. Patients may present with testicular mass mimicking a malignant testicular tumor. In some cases, patients present with acute onset. We report the case of a 51-year-old male who presented with a solid and edematous testicular mass evolving for 4 months. Radiological presentation was not specific, the ultrasound examination objectified a large hetero-echogeneous mass. Tumor markers including α-fetoprotein, β-human chorionic gonadotropin and LDH were normal. A malignant testicular tumor was suspected. Therefore, the patient underwent radical right orchidectomy. Gross examination of the specimen revealed a well circumscribed intratesticular nodule with hemorrhagic cut surface. However, pathological examination revealed a benign testicular tumor composed of dilated thin-walled cavernous vascular spaces filled with red blood cells, compatible with the diagnosis of testicular cavernous hemangioma.

Centris pectoralis clypeata (schrottky, 1908)

description: Centris pectoralis clypeata (Schrottky, 1908)
 Hemisia pectoralis var. clypeata Schrottky, 1908: 142. Junior secondary homonym of C. clypeata Lepeletier, 1841. Junior synonym of C. obsoleta (Moure et al., 2007).
 Type data: This species was apparently described based on a single male collected by János Anisits in Asunción, Paraguay. The current condition and depository of the holotype are currently unknown.
 Comments: Moure (1950) mentioned the variability in the coloration of the pubescence of C. pectoralis Burmeister,1876 (= C.obsoleta) indicating that the varieties described of that species must be suppressed, which would include C. pectoralis var. clypeata and C. pectoralis var. flava (see below). However, the synonymy between this latter variety and C. obsoleta was only formally indicated by Moure et al. (2007).

description: Introduction: Biodeterioration is an irreversible damage caused by microorganisms or their metabolites to various historic and cultural monuments. In numerous studies, the use of various materials in the restoration of historic and cultural monuments, without studying their effects on them growth of biological growth, stimulates the progress of microorganisms. The living organism growth alter the diversity of biological life and intensify their destructive effects. Furthermore, various chemicals that are used as biocides to control or eliminate biodeteriorating agents, have potential risks to human health, restorators and conservators who work permanently in this area. Thus, scientists are looking for new green methods and biomaterials that are suitable substitutes, economically and ecologically compared to the toxic chemicals.Methodology: This study was conducted using library research method and searched in the various databases.Result and discussion: Finding new safe and eco-friendly solution can not only help to preserve the historic and cultural heritage that have great importance in the countries of rich in historic and cultural heritage, but ensure the health and safety of personnel working in the field of conservation and restoration. Some of the biological solutions and new technologiesrelated to this topic are:- Use of microorganisms for the bioproduction of calcium carbonate- Use of natural products such as oils and natural extracts as antimicrobials- Use of green nanoparticles derived from biological sources that have severaladvantages compared to chemical methodsConclusion: The use of new biotechnological methods can be more effective and ecofriendly with less toxicity in preserving cultural heritage.

description: Starting with the Green's functions found for normal diffusion, we construct exact time-dependent Green's functions for subdiffusive equation (with fractional time derivatives), with the boundary conditions involving a linear combination of fluxes and concentrations. The method is particularly useful to calculate the concentration profiles in a multi-part system where different kind of transport occurs in each part of it. As an example, we find the solutions of subdiffusive equation for the system composed from two parts with normal diffusion and subdiffusion, respectively.

description: We have used Langevin dynamics to simulate the forced translocation of linked polymer rings through a narrow pore. For fixed size (i.e. fixed number of monomers) the translocation time depends on the link type and on whether the rings are knotted or unknotted. For links with two unknotted rings, the crossings between the rings can slow down the translocation and are responsible for a delay as the crossings pass through the pore. The results fall on a set of relatively smooth curves for different link families with the translocation time not always increasing with crossings number within the same family. When one ring is knotted the results depend on whether the link is prime or composite and, for the composite case, they depend on whether the knotted or unknotted ring enters the pore first. We find a similar situation for 3-component links where the results depend on whether the link is prime or composite. These results contribute to our understanding of how the entanglement complexity between filaments impacts their translocation dynamics and should be useful for extending nanopore-sensing techniques to probe the topological properties of these systems.

description: Background: Tooth decay is the most common infectious disease that involves all groups, ages and classes of the society. Treatment of dental caries imposes high costs in all countries. Since the plants are safe and abundant natural resources, they have always been one of the major sources of pharmaceuticals. This study aimed to evaluate the antibacterial effect of alcoholic extract of Damaskrose on cariogenic streptococci.Methods: In this study, the antimicrobial effect of ethanol extract of Rosa damascena on the cariogenic streptococci, including Streptococcus mutans, Streptococcus sobrinus, Streptococcus salivarius and Streptococcus sanguis was assessed via microtitre plate method for minimum inhibitor concentration (MIC) and minimum bactricidal concentration (MBC). The effect of the extract on attachment of these bacteria was surveyed. Results were analyzed using one-way analysis of variances.Findings: The minimum inhibitor concentrations for the Streptococcus mutans, Streptococcus sobrinus, Streptococcus salivarius and Streptococcus sanguis were 7.5, 7.5, 15.0, and 15.0 mg/ml, respectively; and minimum bactricidal concentration for these bacteria were 15.0, 7.5, 15.0, 30.0 mg/ml, respectively. In addition, it was shown that different dilutions of Rosa damascena extract decreased the biofilm formation in these bacteria between 43 to 93 percent.Conclusion: Due to the antibacterial effect of Rosa damascena on all four strains of cariogenicbacteria, the extract can be used for prevention and control of dental caries.

description: By considering a sample of Italian manufacturing firms, this paper aims at comparing the R&D performance of foreign (multinational) enterprises with that of home companies. Its methodological innovation consists in adopting a random coefficient treatment model, which allows us to: (i) embed this comparison in a “counterfactual” setting; (ii) and calculate the firms’ “specific treatment effect”. The carrying out of these analyses would not be possible with the use of standard regression tools. The results suggest that the weakness of the (Italian) national R&D production system mainly lies in the “smallness” of its firms: while a home company of large size is able to perform more R&D than a foreign twin, the performance of a home company of small size is worse than that of similar foreign firms. Thus, as for policy implications, we suggest that attracting inward investments should be accompanied by policies aimed at better supporting the growth of home companies.

description: In the recent experiments designed to synthesize the element 115 in the $^{243}$Am+$^{48}$Ca reaction at Dubna in Russia, three similar decay chains consisting of five consecutive $α$-decays, and another different decay chain of four consecutive $α$-decays are detected, and the decay properties of these synthesized nuclei are claimed to be consistent with consecutive $α$-decays originating from the parent isotopes of the new element 115, $^{288}115$ and $^{287}115$, respectively\cite{ogan.03}. Here in the present work, the recently developed deformed RMF+BCS method with a density-independent delta-function interaction in the pairing channel is applied to the analysis of these newly synthesized superheavy nuclei $^{288}115$, $^{287}115$, and their $α$-decay daughter nuclei. The calculated $α$-decay energies and half-lives agree well with the experimental values and with those of the macroscopic-microscopic FRDM+FY and YPE+WS models. In the mean field Lagrangian, the TMA parameter set is used. Particular emphasis is paid on the influence to both the ground-state properties and energy surfaces introduced by different treatments of pairing. Two different effective interactions in the particle-particle channel, i.e., the constant pairing and the density-independent delta-function interaction, together with the blocking effect are discussed in detail.

description: The purpose of this study was to test the hypothesis related with the increase of market power of a large beef packing industry in the state of Mato Grosso, resulting from the merge of this company with another, and from the renting of slaughterhouses from a third. Due to events occurred in the year of 2009; cattle-breeders of the State exposed the hypothesis related with the loss of bargaining power. This phenomenon was widely spread about in the press. The testing of this hypothesis was based on the comparison of relative prices charged in the State before and after the occurrence of those events. Besides, relative amounts of production were also compared. Data analysis consisted of t test, for the equality of means, and Analysis of Variance. Evidences show that the bargaining power of suppliers was preserved, considering that averages of relative prices charged in the market cannot be considered statistically different. In addition, the production recorded in Mato Grosso increased when compared to that obtained in the whole country

description: The objective of this research was to analyze the influence of institutional and organizational environment traits and transformations over the position of a few sugarcane agribusiness of Paraná, Brazil. For this, we analyzed, under the point-of-view of the New Institutional Economics (NIE), the traits of the institutional and organizational environments, in which the study object agribusinesses are inserted. This research was qualitative, and the data collection was conducted by means of interviews and electronic correspondence with representatives of the agribusinesses and with the Bioenergy Producers Association on the state of Paraná (ALCOPAR), bibliographical research and document analysis. The results show that the effects of institutional transformation, as well as those of the organizational environment over the choices of the agribusinesses were the same. This was expected given that the analyzed companies are a part of the same market, economic sector, institutional and organizational environment, and are located within the same state. We verified that changes in the institutional environment directly impacted the forms of transitioning and positioning of the companies. We also confirmed actions regarding the change of the institutional environment made by the agribusinesses, with representatives from all governmental spheres for defending the interest of the sector. We demonstrated that the organizational environment is well structured within the sugarcane SAG of Paraná, and is fundamental for increasing its logistic efficiency

description: We present a hybrid particle/grid approach for simulating incompressible fluids on collocated velocity grids. We interchangeably use particle and grid representations of transported quantities to balance efficiency and accuracy. A novel Backward Semi-Lagrangian method is derived to improve accuracy of grid based advection. Our approach utilizes the implicit formula associated with solutions of Burgers' equation. We solve this equation using Newton's method enabled by $C^1$ continuous grid interpolation. We enforce incompressibility over collocated, rather than staggered grids. Our projection technique is variational and designed for B-spline interpolation over regular grids where multiquadratic interpolation is used for velocity and multilinear interpolation for pressure. Despite our use of regular grids, we extend the variational technique to allow for cut-cell definition of irregular flow domains for both Dirichlet and free surface boundary conditions.

description: Background and Aim: Mutans streptococci are the main cause of tooth decay. Application of natural materials as mouthwash has been effective in reducing the bacterial count. This study aimed to assess the antimicrobial effects of rose water and pomegranate vinegar in comparison with Persica mouthwash on two oral bacteria responsible for tooth decay.Materials and Methods: Strongly adherent strains of Streptococcus mutans and Streptococcus sobrinus were selected for this in vitro study. Antimicrobial effects ofpomegranate vinegar and rose water on microbial count in the biofilm and adhesion potential of bacteria were evaluated by microtiter plate method. Also, the well-platetechnique was used to assess the effect of rose water and pomegranate vinegar in comparison with Persica mouthwash on bacterial growth and proliferation. The obtained resulted were analyzed by one-way ANOVA and Tukey’s post hoc test using Graph Pad Prism version 5 software. Level of significance was set at P=0.05 with 95% confidence interval.Results: Pomegranate vinegar, rose water and Persica decreased plaque formation by S. mutans by 93%, 80% and 68%, respectively. These values for the S. sobrinus were 92%, 57% and 48%, respectively (all Ps<0.001). Pomegranate vinegar was more effective than the other two materials (P<0.001). However, none of these materials eliminated the biofilm. Pomegranate vinegar and Persica mouthwash inhibited the growth of the afore-mentioned bacteria.Conclusion: Within the limitations of this study, it seems that pomegranate vinegar and rose water have the potential to prevent or control the proliferation of S. mutans and S.sobrinus.

description: Magnetic properties of a tetrahedral "Ni_4" molecule are discussed in terms of the Heisenberg model, with magnetic anisotropy terms included, and on the basis of first-principle calculations within the density functional theory. It is shown that the isotropic Heisenberg model does not provide an adequate description of magnetization at low temperatures; an inclusion of single-site anisotropy terms does not help to improve the situation either. We suppose that the magnetostriction of the molecule and hence the dependence of interatomic coupling parameters on the magnetization might be important for an adequate description of magnetic properties. The first-principle calculations confirm the system's general preference for antiferromagnetic coupling, as well as the failure of the isotropic Heisenberg model. A conjugated-gradient search for the relaxed structure of the "Ni_4" molecule in ferromagnetic and antiferromagnetic configurations did not show any clear tendency to diversification of interatomic distances. These calculations however have not yet included the spin-orbit coupling, which can be essential for analyzing the effects of magnetostriction.

description: With this stud, we aimed at comparing costs and productivity of dairy production of two production methods: the traditional system and the confinement system denominated freestall. The methodology used in this research is characterized as a study of compared cases, of descriptive nature and qualitative approach. The case studies were conducted in two rural dairy production properties, located at West Santa Catarina, Brazil, one in the traditional management system (pastures in the form of pickets) and the other in a confinement system (freestall). The data collection occurred in January of 2014, filling electronic spreadsheets with data regarding fixed assets, cash flow, sales revenue, production costs and productivity. With the data analysis, we verified that the freestall system provides a profit margin 8.55% superior for the liter of produced milk, due mainly to the higher productivity of approximately 78.8% of liters, compensating the cost difference of 13.57% higher than that of the property using the traditional production system. We conclude that the freestall management system provides a better economic result for the dairy activity, considering the similar production structures of the properties analyzed in this research.

description: Background and Objectives: The most prevalent and worldwide oral disease is dental caries that affects a significant proportion of the world population. There are some classical approaches for control, prevention and treatment of this pathologic condition; however, the results are still not completely successful. Therefore new methods are needed for better management of this important challenge. Chitosan is a natural and non-toxic polysaccharide with many biological applications, particularly as an antimicrobial agent. Chitosan nanoparticle is a bioactive and environment friendly material with unique physicochemical properties. The aim of the present study was to investigate the antimicrobial effect of chitosan and nano-chitosanon the most important cariogenic Streptococci.Materials and Methods: For evaluation of antimicrobial effect of chitosan and nano-chitosan against oral Streptococcibroth micro-dilution method was carried out for four bacterial species; Streptococcus mutans, Streptococcus sobrinus, Streptococcussanguis and Streptococcus salivarius. Also the effect of these materials on adhesion of above bacteria was evaluated.One-way ANOVA and post hoc Tukey test were used for statistical analysis.Results: The MICs of chitosan for S. mutans, S. sanguis, S. salivarius and S. sobrinus were 1.25, 1.25, 0.625 and 0.625 mg/ mL, respectively. The MIC of chitosan nanoparticle for S. mutans, S. salivarius and S. sobrinus was 0.625 mg/mL and for S. sanguis was 0.312 mg/mL. Chitosan and chitosan nanoparticles at a concentration of 5 mg/mL also reduced biofilm formationof S. mutans up to 92.5% and 93.4%, respectively.Conclusion: The results of this study supported the use of chitosan and chitosan nanoparticles as antimicrobial agentsagainst cariogenic Streptococci.

description: This work is a result of a research on the process of training value that constitutes the foundation over which articulate the interorganizational relations present in the agribusiness production chains. These are comprised of distinct organizations united by a relational component not yet well explained by the existing approaches. The main objective consists of the search for a better understanding of how the construction process of interorganizational relations are established under the perspective of value creation. The research was developed using the milk production chain in Rio Grande do Sul, Brazil. As results, we highlight that the market relations differ from the long-term partnerships formed within the milk production chain regarding the performance of transactional and relational value elements. The first are more significant in market relations, and the relational value elements constitute the foundation of long-term partnerships

description: Within the dinuclear system (DNS) conception, instead of solving Fokker-Planck Equation (FPE) analytically, the Master equation is solved numerically to calculate the fusion probability of super-heavy nuclei, so that the harmonic oscillator approximation to the potential energy of the DNS is avoided. The relative motion concerning the energy, the angular momentum, and the fragment deformation relaxations is explicitly treated to couple with the diffusion process, so that the nucleon transition probabilities, which are derived microscopically, are time-dependent. Comparing with the analytical solution of FPE, our results preserve more dynamical effects. The calculated evaporation residue cross sections for one-neutron emission channel of Pb-based reactions are basically in agreement with the known experimental data within one order of magnitude.

description: Innovation is one of the main forces that orient the entrepreneurial economic development and competitiveness. Within the food industry, innovation gains great importance due to demographic growth, increase in income and urbanization, and the consequent change in the profile of food in take, regarding variety, quantity and quality.The present study sought to analyze the innovation, or that which hinders this process, within the companies of wheat derivative industry in Brazil. Primary data were obtained by a structured questionnaire applied to companies, and complemented with secondary data related to the patents of this industry.We verified that most companies are not innovating. The type of innovation most adopted is product innovation and company innovation, with low degree of appropriability. For the companies that did not innovate, the economic factor is the main restriction, and the market dominium by large companies would be the main reason for companies to not innovate. There is a series of opportunities for the processing industry to innovate, which would benefit all segments of the production chain.
title: Modulation of Calcium signalling by F-actin during maturation and fertilization of starfish oocytes
Creators: name: Puppo Studer, Agostina Margarita
Publisher: name: The Open University
Year: 2010

description: The Calcium ion (Ca2+) is a universal intracellular messenger that is implicated in the regulation of a great variety of intracellular processes. Among them, there is the meiotic maturation of oocytes from several species and their fertilization.

The cell model system chosen for the work of this thesis has been the starfish oocytes. They constitute an exceptional model to study the properties of the dynamic release of Ca2+. First, the cells are large and nearly transparent, making them suitable for imaging experiments after microinjection of fluorescent markers. Immature oocytes extracted from the gonad are arrested at the prophase stage of the first meiotic division. Overcoming the meiotic arrest (maturation), is induced by the application of the maturing hormone 1-Methyladenine (1-MA), whose action involves intracellular Ca2+ transients. During the maturation process, the oocytes develop their ability to be successfully activated by a fertilizing spermatozoon by liberating higher levels of calcium. 1-MA also induces dramatic actin cytoskeleton rearrangements.

In the present work, the relevance of the actin cytoskeleton in the modulation of the Ca2+ signals generated by hormonal stimulation and by the sperm has been studied. For this purpose, actin-specific disrupting agents and a specific antibody targeting the actin binding protein depactin have been delivered into living cells by needle microinjection, to study their effects using confocal laser fluorescent microscopy. Thus, the Ca2+ increases induced either by 1-MA, by the fertilizing sperm or by the injection of exogenous InsP3. which is the canonical Ca2+ mobilizer second messenger, have been monitored with video fluorescent microscopy. The results described indicate that actin filaments play direct and indirect roles in modulating the intracellular Ca2+ mobilization induced by the maturation process triggered by 1-MA as well as in the Ca2+ responses induced by the sperm.

description: For its large participation on Brazilian GDP, the agricultural sector represents today a fertile field for studies and researches. In this context, the objective of this study was to identify the profile of farmers from the Middle-North region of Mato Grosso, Brazil, and their learning demands. Based on the theory of studies on informal learning and on the working location, we conducted a basic interpretive qualitative research with the managers of four rural unions from the Middle-North of the state of Mato Grosso. For the data analysis, the category analysis method based on Lankshear and Knobel (2008) was used. It was possible to perceive the activity of the unions regarding the needs and interests of its represented concerning political and social aspects. Regarding the learning, we verified that there are still learning demands from control and trade administration, and productive and information technology aspects, in addition to the climate and soil characteristics.

 Centris poÇograndensis Schrottky, 1902b: 578, 579. Junior synonym of C.collaris Lepeletier, 1841 (Moure, 2002).
 Type data: This species was described based on a single male specimen (Figs. 1A, B) collected in Poço Grande, an old farm near the city of Juquiá (Moure, 2002). The holotype is currently housed at MZSP and it has the following data label: [black rimmed] Centris poÇograndensis Shrottky ♂ Poço Grande Brasil [handwritten]\ [red label with black rim] Melanocentris poÇograndensis (Schr.) ♂ [handwritten] P. Moure det [printed] 1945 [handwritten] Ducke det. 15. Unico! [handwritten].
 Comments: Friese (1904) erroneously mentioned this species as junior synonym of C. dorsata Lepeletier, 1841. Centris collaris has been recorded in Paraguay and in the Brazilian states of Mato Grosso, Minas Gerais and São Paulo (Moure et al., 2007).

description: The generalized entropic measure, which is optimized by a given arbitrary distribution under the constraints on normalization of the distribution and the finite ordinary expectation value of a physical random quantity, is considered and its Lesche stability property (that is different from thermodynamic stability) is examined. A general condition, under which the generalized entropy becomes stable, is derived. Examples known in the literature, including the entropy for the stretched-exponential distribution, the quantum-group entropy, and the kappa-entropy are discussed.

description: Wireless power transfer (WPT) is a promising technology to prolong the lifetime of the sensors and communication devices, i.e., workers, in completing crowdsourcing tasks by providing continuous and cost-effective energy supplies. In this paper, we propose a wireless powered spatial crowdsourcing framework which consists of two mutually dependent phases: task allocation phase and data crowdsourcing phase. In the task allocation phase, we propose a Stackelberg game based mechanism for the spatial crowdsourcing platform to efficiently allocate spatial tasks and wireless charging power to each worker. In the data crowdsourcing phase, the workers may have an incentive to misreport its real working location to improve its utility, which causes adverse effects to the spatial crowdsourcing platform. To address this issue, we present three strategyproof deployment mechanisms for the spatial crowdsourcing platform to place a mobile base station, e.g., vehicle or robot, which is responsible for transferring the wireless power and collecting the crowdsourced data. As the benchmark, we first apply the classical median mechanism and evaluate its worst-case performance. Then, we design a conventional strategyproof deployment mechanism to improve the expected utility of the spatial crowdsourcing platform under the condition that the workers' locations follow a known geographical distribution. For a more general case with only the historical location data available, we propose a deep learning based strategyproof deployment mechanism to maximize the spatial crowdsourcing platform's utility. Extensive experimental results based on synthetic and real-world datasets reveal the effectiveness of the proposed framework in allocating tasks and charging power to workers while avoiding the dishonest worker's manipulation.

Exploring the connection between solar energetic particles at the Sun and in the heliosphere

description: Solar flares are the product of a rapid release of energy due to magnetic reconnection, which results in outward-propagating magnetic fields and closed fluxed tubes below the reconnection site. The energy released during a solar flare is separated into thermal and non-thermal particle energy, as well as turbulence, which is a vital mechanism in transferring energy. The energy released manifests in many ways, such as acceleration of electrons and ions and an increase in thermal energy which is radiated away across the electromagnetic spectrum. Observations suggest that during the impulsive phase a significant amount of the released energy is used to accelerate electrons both downwards into the Sun and outwards into the Heliosphere. This poster discusses the aims of the PhD project which is a part of a larger study which will explore the connection between solar flare energetic electrons observed at the Sun and in the heliosphere. Current work will be discussed (i.e. mapping turbulence in a solar flare) as well as the next steps in the project.
