Diário da Constituinte [gravação de vídeo] : [programa n. 186C] 

Cidadãos opinam sobre o fim dos marajás no funcionalismo público. O Deputado Victor Faccioni (PDS-RS) apresenta emenda estabelecendo um piso máximo para os servidores públicos, correspondente a 90% do que recebem os ministros do Supremo Tribunal Federal. O Deputado Arolde de Oliveira (PFL-RJ) considera louvável a iniciativa do parlamentar para moralizar o serviço público. O Deputado Ruben Figueiró (PMDB-MS) informa que a medida é conveniente. O Deputado Fernando Gasparian (PMDB-SP) discorda do Deputado Victor Faccioni e sugere outra medida estabelecendo um teto máximo para todos, mas que não tenha como base o salário dos ministros do STF. Constituintes moderados do PMDB formam o Centro Democrático, o Centrão. O líder do Centrão Expedito Machado (PMDB-CE) opina sobre a divisão do PMDB e diz que a intenção do seu grupo é fortalecer o partido. O Deputado Aloisio Vasconcellos (PMDB-MG) declara que a partir de 1988 haverá uma reformulação partidária e que é inquestionável a necessidade de partidos fortes. Será entregue ao Presidente da Assembleia Nacional Constituinte (ANC), Deputado Ulysses Guimarães, o novo esboço do projeto de Constituição. O Senador Afonso Arinos (PFL-RJ) define o parlamentarismo como um sistema de governo em que o presidente é o chefe de Estado e o primeiro-ministro é o chefe de governo, sendo que o primeiro tende para a estabilidade e o segundo para a eficácia.

Olympic Coast National Marine Sanctuary Habitat Mapping: Survey report and classification of side scan sonar data from surveys HMPR-114-2004-02 and HMPR-116-2005-01.

The Olympic Coast National Marine Sanctuary (OCNMS) continues to invest significant resources into seafloor mapping activities along Washington’s outer coast (Intelmann and Cochrane 2006; Intelmann et al. 2006; Intelmann 2006). Results from these annual mapping efforts offer a snapshot of current ground conditions, help to guide research and management activities, and provide a baseline for assessing the impacts of various threats to important habitat. During the months of August 2004 and May and July 2005, we used side scan sonar to image several regions of the sea floor in the northern OCNMS, and the data were mosaicked at 1-meter pixel resolution. Video from a towed camera sled, bathymetry data, sedimentary samples and side scan sonar mapping were integrated to describe geological and biological aspects of habitat. Polygon features were created and attributed with a hierarchical deep-water marine benthic classification scheme (Greene et al. 1999). For three small areas that were mapped with both side scan sonar and multibeam echosounder, we made a comparison of output from the classified images indicating little difference in results between the two methods. With these considerations, backscatter derived from multibeam bathymetry is currently a costefficient and safe method for seabed imaging in the shallow (<30 meters) rocky waters of OCNMS. The image quality is sufficient for classification purposes, the associated depths provide further descriptive value and risks to gear are minimized. In shallow waters (<30 meters) which do not have a high incidence of dangerous rock pinnacles, a towed multi-beam side scan sonar could provide a better option for obtaining seafloor imagery due to the high rate of acquisition speed and high image quality, however the high probability of losing or damaging such a costly system when deployed as a towed configuration in the extremely rugose nearshore zones within OCNMS is a financially risky proposition. The development of newer technologies such as intereferometric multibeam systems and bathymetric side scan systems could also provide great potential for mapping these nearshore rocky areas as they allow for high speed data acquisition, produce precisely geo-referenced side scan imagery to bathymetry, and do not experience the angular depth dependency associated with multibeam echosounders allowing larger range scales to be used in shallower water. As such, further investigation of these systems is needed to assess their efficiency and utility in these environments compared to traditional side scan sonar and multibeam bathymetry.

Benthic habitat mapping in the Olympic Coast National Marine Sanctuary: Classification of side scan sonar data from survey HMPR-108-2002-01: Version I

In September 2002, side scan sonar was used to image a portion of the sea floor in the northern OCNMS and was mosaiced at 1-meter pixel resolution using 100 kHz data collected at 300-meter range scale. Video from a remotely-operated vehicle (ROV), bathymetry data, sedimentary samples, and sonar mapping have been integrated to describe geological and biological aspects of habitat and polygon features have been created and attributed with a hierarchical deep-water marine benthic classification scheme (Greene et al. 1999). The data can be used with geographic information system (GIS) software for display, query, and analysis. Textural analysis of the sonar images provided a relatively automated method for delineating substrate into three broad classes representing soft, mixed sediment, and hard bottom. Microhabitat and presence of certain biologic attributes were also populated into the polygon features, but strictly limited to areas where video groundtruthing occurred. Further groundtruthing work in specific areas would improve confidence in the classified habitat map. (PDF contains 22 pages.)

Fiber Bragg Gratings, IT Techniques and Strain Gauge Validation for Strain Calculation on Aged Metal Specimens

This paper studies the feasibility of calculating strains in aged F114 steel specimens with Fiber Bragg Grating (FBG) sensors and infrared thermography (IT) techniques. Two specimens have been conditioned under extreme temperature and relative humidity conditions making comparative tests of stress before and after aging using different adhesives. Moreover, a comparison has been made with IT tecniques and conventional methods for calculating stresses in F114 steel. Implementation of Structural Health Monitoring techniques on real aircraft during their life cycle requires a study of the behaviour of FBG sensors and their wiring under real conditions, before using them for a long time. To simulate aging, specimens were stored in a climate chamber at 70 degrees C and 90% RH for 60 days. This study is framed within the Structural Health Monitoring (SHM) and Non Destructuve Evaluation (NDE) research lines, integrated into the avionics area maintained by the Aeronautical Technologies Centre (CTA) and the University of the Basque Country (UPV/EHU).

Eine zusätzliche Möglichkeit für die Ostseedorsch-Fischerei: Steerte aus 90° gedrehtem Netztuch

In 2004, comparative selectivity investigations were made with the now legal BACOMA codend of 110 mm mesh opening and alternative codends made of netting turned 90° of similar mesh openings on both commercial boats and on research vessels. The results show a certain variability of the BACOMA results – depending on ship type and season (L50 varying between 36,8 and 40,6) – and a general equal efficiency of codends made of netting turned 90° of the same mesh opening. Underwater observations and reduced performance of codends of equal circumference in meshes as the joining round at the end of the tapered part of the trawl indicate the need to reduce the relation of the cir-cumferences of codend and extension to 1 to 0.7 to achieve optimum fit and selectivity.

Ostseedorschselektion - bestehende und vorgesehene neue technische Maßnahmen

Since the beginning of the nineties the situation of the Baltic cod stock is deteriorating constantly. The fishery administration (International Baltic Sea Fisheries Commission) tries to counter this by issuing new technical measures. Existing measures (raise of mesh opening from 105 to 120 mm, “Danish” and “Swedish” escape windows) and newly introduced technical measures (BACOMA codend and raise of the mesh opening in conventional codends to 130 mm) show a number of deficiencies putting their efficiency in doubt. Available well tested alternatives to the newly introduced measures without their negative side effects (codends made of netting turned by 90°, and other designs) are presently left out of regard. Models of socioeconomic effects are likewise ignored.

Influence of Humidity on Fiber Bragg Grating Sensors

We demonstrate the influence of the relative humidity (RH) on the wavelength of fiber Bragg grating sensors (FBGS), performing tests with five FBGS at different humidity and temperature conditions. These tests were performed in a climate chamber whose RH changes according to a scheduled profile from 30% to 90%, in steps of 10%. These profiles were repeated for a wide range of temperatures from to , in steps of . Two different types of instrumentation methods have been tested, spot welding and epoxy bonding, in two different materials, steel and carbon fiber reinforced polymer (CFRP). We discuss the results for each type of sensor and instrumentation method by analyzing the linearity of the Bragg wavelength with RH and temperature.
