Performance of Typha australis cut at three different heights

The response of Typha australis to stem cut at three different heights was studied for four weeks. This was carried out in the field between August and September 2003. Matured Typha australis naturally occuring along the stream within the Institute Integrated Fish Pond Complex, New Bussa were randomly selected. The shoots were cut at 10cm, 20cm, and 30cm, above the soil level. The responses of the plant were assessed. Plant cut at 10cm showed re-growth for one week and later died, while those cut at 20cm and 30cm showed re-growth through out the period of experiment. Result showed previous height between 10cm and 20cm is significant (P>0.05) between 10cm and 30cm height re-growth rates. But plant cut at 20cm and 30cm showed no significant (P>0.05), in height. The results show the susceptibility of Typha australis to stem cut at 10cm or below. Typha australis cut at 10cm above soil level are not likely to survival

Phase unwrapping based on branch cut placing and reliability ordering

A new 2-D quality-guided phase-unwrapping algorithm, based on the placement of the branch cuts, is presented. Its framework consists of branch cut placing guided by an original quality map and reliability ordering performed on a final quality map. To improve the noise immunity of the new algorithm, a new quality map, which is used as the original quality map to guide the placement of the branch cuts, is proposed. After a complete description of the algorithm and the quality map, several wrapped images are used to examine the effectiveness of the algorithm. Computer simulation and experimental results make it clear that the proposed algorithm works effectively even when a wrapped phase map contains error sources, such as phase discontinuities, noise, and undersampling.

A CUT, o novo sindicalismo e as reconstruções da memória do movimento operário brasileiro (1983-1990)

Este trabalho tem por objetivo analisar as proposições políticas da CUT na década de 1980, bem como a memória que esta entidade construiu sobre o passado do movimento operário brasileiro. Isso se fará através da observação de uma prática, que segundos os membros da entidade, seria mais combativa, inovadora e defensora dos reais interesses da classe trabalhadora. O que a levou a se colocar como representante de um novo sindicalismo, contrapondo-se a o que a CUT denomina velho sindicalismo, colaboracionista, clientelista e pouco combativo. O trabalho se utiliza das leituras que a CUT faz ao longo da construção das bases ideológicas de seu sindicalismo e sobre a atuação sindical anterior ao golpe civil-militar de 1964, sendo este um instrumento de criação de sua identidade política e também um referencial crucial para o estabelecimento de suas estratégias e propostas de ação no campo sindical, além de seu projeto político. Utilizando-se das referencias teóricas da nova história política, da cultura política, do conceito de memória e das relações entre memória-identidade e identidade-projeto, o trabalho pretende investigar como a CUT, a partir de sua fundação e nos primeiros anos de sua atuação se apoiou neste discurso que desqualificava as lideranças sindicais que atuaram antes de 1964.

Diode-pumped continuous wave and Q-switched operation of a c-cut Tm,Ho:YAlO3 laser

We report on a diode-pumped, cryogenic and room temperature operation of a Tm,Ho:YAlO3 (c-cut) laser. In a temperature of 77 K, an optical-optical conversion efficiency of 27% and a slope efficiency of 29% were achieved with the maximum continuous-wave (CW) output power of 5.0 W at 2.13 mu m. Acousto-optic switched operation was performed at pulse repetition frequency (PRF) from 1 kHz to 10 kHz, the highest pulse energy of 3.3 mJ in a pulse duration of 40 ns was obtained. In room temperature (RT), the maximum CW power of Tm,Ho:YAlO3 laser was 160 mW with a slope efficiency of 11% corresponding to the absorbed pump power. (C) 2008 Optical Society of America.
