Nas regiões Centro-Oeste e Sul do Brasil, a cultura da erva-mate (Ilex paraguariensis) constitui-se uma importante fonte de extrativismo florestal, além diversificar renda, principalmente na agricultura familiar. A erva-mate, como outras espécies florestais, é infectada por diversos patógenos, o gênero Fusarium, causador podridão-de-raízes. Os patógenos possuem ampla variabilidade genética, mes...

Women who rate their male partner as more masculine tend to prefer more masculine faces. However, it is unclear whether a preference for masculinity causes women to select masculine partners, or to perceive their current partner as more masculine. By incorporating multiple measures of male masculinity, we establish that women’s preference for facial masculinity in short-term partners is correla...
Core network capacity planning is the process of ensuring that sufficient bandwidth is provisioned such that the committed core network service-level agreements can be met. The best practices described in this paper collecting demand matrices, determining overprovisioning factors, and running simulations are the basis of the design principles for the Cisco TM MATE TM portfolio, especially (from...
Analysis and Simulation of ZVS Methods in Full Bridge Converters and Realization of a 3 KW Prototype
One of the difficulties with PWM switching converters is high switching loss and electromagnetic interference due to switching at non-zero voltage and current, which limits the operating frequency. In order to reduce the converter volume and weight (by increasing the frequency) and reducing switching losses, zero voltage and current switching methods are recommended. In this paper, four main ze...

melamine is a potentially hazardous compound and one of the major concerns especially in dairy products and pet foods. in the present study a sensitive, simple and reliable method for extraction and determination of melamine in infant milk and coffee mate has been developed. this method consists of an initial extraction in buffer media prepared by formic acid and sodium formate, followed by pro...
The current study provides the first evolutionarily-informed direct comparison of actual parents’ and offspring’s mate preferences. We compared students’ (N = 300) average rankings of 13 traits for desirability in an ideal mate with their parents’ (N = 238) rankings of the same traits for their offspring’s ideal mate. Parents ranked religion higher than offspring, whereas offspring ranked physi...
In this research article of modeling Underwater Wireless Sensor Network Simulators, we provide a comprehensive overview of the various currently available simulators used in UWSN modeling. In this work, we compare their working environment, software platform, simulation language, key features, limitations and corresponding applications. Based on extensive experimentation and performance analysi...
Precopulatory mate guarding (PCMG) is generally assumed to be costly for both sexes. However, males may gain by displaying long-lasting mate guarding under strong male-male competition. Surprisingly, the potential for females to benefit from being held by males has been largely overlooked in previous studies. In Gammarus pulex, an amphipod crustacean, PCMG lasts several weeks, yet females are d...
