Reconhecimento do grupo rizibilis; descrição de uma nova espécie de Hyla (Amphibia, Anura)

Hyla ranki, sp. n., is described from the state of Minas Gerais, southeastern Brazil. This new species resembles Hyla rizibilis Bokermann, 1964. The advertising call and the tadpole are also described. Observations on the biology of the new species are referred and the recognition of the group rizibilis, constituted by H. rizibilis and H. ranki, sp. n., is proposed. Hyla mirim B. Lutz, 1972 is synonymized with H. rizibilis.433440Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP

Reproductive behavior of Cycloramphus dubius Miranda-Ribeiro (Amphibia, Anura, Leptodactylidae)

Cycloramphus dubius Miranda-Ribeiro. 1920 is a frog species from the coastal Atlantic Forest in Southeastern Brazil. It uses waterfalls of forested rivulets as breeding sites. The eggs are placed outside of water, between rock crevices or roots constantly wetted by water dripping. Clutches have about 60 eggs, and the tadpoles grow attached to rocks, out of water. Males of this species exhibit parental care, biting and/or pushing away strange objects approaching the egg masses. Two types of calls were identified in the spectrograms. The advertisement calls consist of juxtaposed pulses lasting 200ms; the aggressive calls, also have the short pulses structure, and last around 300ms. The aggressive calls are emitted during territorial invasion.233237Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP

Trnsys simulation results of an existing monitored small scale CHCP system and mathematical model adaptations of the air-cooled ammonia chiller and CHP prototypes

This work is a TRNSYS simulation of solar thermal system working together with an existing small sized CHCP (Combinet Heat Cooling and Power) demonstration project, included in the workpackage 5 (simulation) of the PolySMART project. The first objective of this work is to fine tune simulation parameters of the simulation Units (or Types), based on monitoring data collected during the first semester of 2010. The second objective is to further develop the mathematical models of type 107 (Hot Water-Fired Single-Effect Absorption Chiller) and type 120 (HYDROGEMS: Diesel Engine Generator System (DEGS) - Version 1.1). This will tackle the remaining differences between the real and simulated systems. These differences are due to the fact that both the CHP and the Ammonia-Water Air Cooled Chiller are prototypes. The third objective is to simulate the performance of different thermal collectors, some of which are also prototypes, and choose a proper solution for future experiments. The forth objective is to compare local weather data sets, collected on site since 2007, with proven standard data sets. Further work may be developed regarding the fan coils used to carry in/out heat

Monitoring Results of a Small Scale CHCP System

A small scale trigeneration system for combined heat, cold and power production was developed and installed at the Laboratório Nacional de Energia e Geologia, I.P. campus in Lisbon, Portugal. This system is one of the twelve experimental trigeneration systems being developed and tested across Europe within the PolySMART project. The CHCP system main constituents are a purpose made CHP prototype with an estimated 27kW maximum heat capacity and 9,6kW maximum electrical capacity and a TDC prototype with 8kW cooling power. The hydraulic scheme is presented and briefly analyzed. The data obtained during the monitoring of the system during heat and cold seasons is presented and analyzed for the global system. Main components behavior is analyzed with regard of their real performance when installed on a CHCP system
