Diário da Constituinte [gravação de vídeo] : [programa n. 656]

Os constituintes começaram a apresentar os pedidos de Destaques para votação das emendas em separados. O prazo para a entrega dos requerimentos vai até o dia 22.7.1988 a meia-noite. Cada constituinte tem o direito de apresentar 4 (quatro) Destaques. O primeiro a chegar foi o Líder do PMDB, Nelson Jobim. Até o final da tarde mais de 180 constituintes já tinham apresentado seu Destaque, como foi o caso dos deputados Francisco Kuster (PMDB-SC) e Nelson Frederich (PMDB-PR). O Centrão que fez algumas reuniões anteriormente, já sabe o que quer retirar do texto e acredita que têm votos suficientes para isto. Os constituintes considerados progressistas acham que os temas que foram objeto de acordo no 1º Turno devem permanecer no texto e acreditam que pouca coisa deve ser modificada. Jair Menegheli (Presidente da CUT) disse que os sindicalistas já estão preparados para a defesa de seus direitos no 2º Turno.

Falsche Fische – ein Bericht über die Schwierigkeiten der Identifizierung einer „Seezunge“

In the last years German food control laboratories have established proof of a significant number of cases of incorrectly labelled flatfish on the German market. A flatfish offered as sole (Solea vulgaris) in Southern Germany served as an example for mislabelled flatfish and for the difficulties food control laboratories may encounter and to identify products of unknown origin. Morphometric and meristic examination, as well as isoelectric focusing of sarcoplasmic proteins, PCR-based DNA-analysis failed to identify the fish. By using these methods, it only could be excluded that the fish belonged to the species of Solea vulgaris or another described flatfish species. DNA sequencing of an amplicon gave a sequence identical to a sequence in GenBank, which, however, turned out to be incorrectly assigned to Solea vulgaris. More research about characterization and identification of tropical flatfish is recommended, because of the growing importance of these fishes for the European market.

Sind die bestehenden Regulierungsmaßnahmen für die Flunderfischerei in der südwestlichen Ostsee sinnvoll?

The reliability of the international minimum landing size of 25 cm for the flounder stock of ICES Sub-divisions 24 and 25 as well as national bans on landing female flounder during the spawning time is investigated on German samples taken in Sub-division 24. The results of the analyses of growth, sex ratio, the proportion of mature flounder, and yield curves show that 25 cm is a convenient regulation measure but it would be reliable to have an international ban on landing female as well as male flounder during spawning time.

Untersuchungen des Zanderbestandes in den deutschen Küstengewässern der Ostsee von 1992 bis 2002

Pike-perch is an important resource for the coastal fishery in the brackish waters of the eastern part of the coast. For the conservation of the stocks regulation measures (minimum landing size, closed season and minimum mesh size) have been introduced since many years. Basic biological material of the last decade sampled from the commercial fishery and for recruitment by a standard trawl survey. For the “Eastern stock” this paper presents the results concerning age distribution, year-class strengths, growth, proportion spawners, natural mortality and yield-per-recruit analyses.

Konzept für eine bestandsschonendere Nutzung der Dorschvorkommen in der westlichen Ostsee

The introduction of a long-term management plan for the cod socks by the International Baltic Sea Fishery Commission (IBSFC) to ensure stable and high yields and to conserve the fish stocks of the Baltic demands certain conservation measures. One is the use of the Total Allowable Catches (TACs) based on precautionary approches. In addition the exploitation pattern and the selectivy of trawls shall be improved to increase the spawning stock biomass and to reduce the presently high discard rates. The contributation demonstrates by means of model calculations for the cod stock of the ICES Sub-divisions 22 to 24 ( Western Baltic ) the short- and long-term effects of an improvement of the trawl selectivity on stock size, yields and profit.

Deutsche und internationale Dorschfischerei in der Ostsee im Jahr 1998

In 1998 the longtime series of the standardized bottom trawl surveys conducted in the western Baltic (ICES Sub-division (SD) 22 and 24 since 1978) during spring and autumn and also in the eastern Baltic (ICES Sub-division since 1993) during spring were continued. The results of the surveys as well as those of a sampling programme carried out on board of commercial cutters (mainly financed by an EU study project) and on the market, the investigation of the survival rate of the discards, and the landing statistics are the basis of the analysis of the German and international cod fishery in 1998. The German cod fishery was concentrated on the ICES SD 22 and 24 (total landings 9722 t). The total landings from the fishing grounds east off Bornholm, the traditional German fishing ground, amounted only to about 1270 t. The German cod quota was utilized at 64 %. The fishery in the ICES SD 22 and 24 was characterized by a discard rate of undersized cod of 13 %. That corresponds to about 7.3 million specimens of 0-group, one- and two-years-old youngfish, respectively. The total international cod landings of the Baltic amounted to 101 500 t. In comparison with 1997 (total landings 129 600 t) the landing decreased by 23 %. The percentage utilization of the cod TAC (1998: 140 000 t) amounted to 74 % in 1998.

The Relevance of Relative Position in Ultimatum Games

This paper investigates the effect of focal points and initial relative position in the outcome of a bargaining process. We conduct two on-line experiments. In the first experiment we attempt to replicate Güth, Huck and Müller's (2001) results about the relevance of equal splits. In our second experiment, we recover the choices of participants in forty mini-ultimatum games. This design allows us to test whether the equal split or any other distribution or set of distributions are salient. Our data provide no support for a focal-point explanation but we find support for an explanation based on relative position. Our results confirm that there is a norm against hyper-fair offers. Proposers are expected to behave selfishly when the unselfish distribution leads to a change in the initial relative position.

Raumfigurationen und Macht in Atemschaukel

[EN] Atemschaukel approaches the falling apart and survival in a historically loaded space, such as a labour camp. This novel offers a relevant research field for the space analysis, focused from the perspective of the Spatial Turn, as not only this theoretical frame but also Herta Müller herself conceive of space as a process, unterstood as a reciprocal interaction with the social practice, thus as a spatial and social construct. The representation of space in Atemschaukel is described in this article as a “swinging movement between boxes and abyss”, where the discourse of Leopold Auberg’s memories oscillates between closed and square spaces, on one hand, and open and giddy spaces, on the other hand. In this oscillating movement it is the open spaces that will most clearly show the process of inner destruction of the subject in such oppressive situations as on labour camps, as well as the permanent damages of deportation.

Three-photon-excited upconversion luminescence of YVO4 single crystal by infrared femtosecond laser irradiation

We report on the upconversion luminescence of a pure YVO4 single crystal excited by an infrared femtosecond laser. The luminescent spectra show that the upconversion luminescence comes from the transitions from the lowest excited states T-3(1), T-3(2) to the ground state (1)A(1) of the VO43-. The dependence of the fluorescence intensity on the pump power density of laser indicates that the conversion of infrared irradiation to visible emission is dominated by three-photon excitation process. We suggest that the simultaneous absorption of three infrared photons promotes the VO43- to excited states, which quickly cascade down to lowest excited states, and radiatively relax to ground states, resulting in the broad characteristic fluorescence of VO43-.

Zum Umrechnungsfaktor - Anlandegewicht (frisch, ausgenommen) in Lebendgewicht - für Dorsch

The conversion factor (UF) was investigated regarding the dependence on fishing season, fishing area, and total length. It was found that during the first half of the year the mean value was higher (UF = 1.24) than in the second half (UF = 1.16). The difference was mainly caused by the different gonad development. The factor was also different between the ICES Sub-divisions 22/24 and 25. The dependence of the conversion factor on total length could be proved.

Fermionic quantum systems. Part I: Phase transitions in quantum dots. Part II: Nuclear matter on a lattice

In the first part I perform Hartree-Fock calculations to show that quantum dots (i.e., two-dimensional systems of up to twenty interacting electrons in an external parabolic potential) undergo a gradual transition to a spin-polarized Wigner crystal with increasing magnetic field strength. The phase diagram and ground state energies have been determined. I tried to improve the ground state of the Wigner crystal by introducing a Jastrow ansatz for the wave function and performing a variational Monte Carlo calculation. The existence of so called magic numbers was also investigated. Finally, I also calculated the heat capacity associated with the rotational degree of freedom of deformed many-body states and suggest an experimental method to detect Wigner crystals.

The second part of the thesis investigates infinite nuclear matter on a cubic lattice. The exact thermal formalism describes nucleons with a Hamiltonian that accommodates on-site and next-neighbor parts of the central, spin-exchange and isospin-exchange interaction. Using auxiliary field Monte Carlo methods, I show that energy and basic saturation properties of nuclear matter can be reproduced. A first order phase transition from an uncorrelated Fermi gas to a clustered system is observed by computing mechanical and thermodynamical quantities such as compressibility, heat capacity, entropy and grand potential. The structure of the clusters is investigated with the help two-body correlations. I compare symmetry energy and first sound velocities with literature and find reasonable agreement. I also calculate the energy of pure neutron matter and search for a similar phase transition, but the survey is restricted by the infamous Monte Carlo sign problem. Also, a regularization scheme to extract potential parameters from scattering lengths and effective ranges is investigated.

Crystals that count! Physical principles and experimental investigations of DNA tile self-assembly

Algorithmic DNA tiles systems are fascinating. From a theoretical perspective, they can result in simple systems that assemble themselves into beautiful, complex structures through fundamental interactions and logical rules. As an experimental technique, they provide a promising method for programmably assembling complex, precise crystals that can grow to considerable size while retaining nanoscale resolution. In the journey from theoretical abstractions to experimental demonstrations, however, lie numerous challenges and complications.

In this thesis, to examine these challenges, we consider the physical principles behind DNA tile self-assembly. We survey recent progress in experimental algorithmic self-assembly, and explain the simple physical models behind this progress. Using direct observation of individual tile attachments and detachments with an atomic force microscope, we test some of the fundamental assumptions of the widely-used kinetic Tile Assembly Model, obtaining results that fit the model to within error. We then depart from the simplest form of that model, examining the effects of DNA sticky end sequence energetics on tile system behavior. We develop theoretical models, sequence assignment algorithms, and a software package, StickyDesign, for sticky end sequence design.

As a demonstration of a specific tile system, we design a binary counting ribbon that can accurately count from a programmable starting value and stop growing after overflowing, resulting in a single system that can construct ribbons of precise and programmable length. In the process of designing the system, we explain numerous considerations that provide insight into more general tile system design, particularly with regards to tile concentrations, facet nucleation, the construction of finite assemblies, and design beyond the abstract Tile Assembly Model.

Finally, we present our crystals that count: experimental results with our binary counting system that represent a significant improvement in the accuracy of experimental algorithmic self-assembly, including crystals that count perfectly with 5 bits from 0 to 31. We show some preliminary experimental results on the construction of our capping system to stop growth after counters overflow, and offer some speculation on potential future directions of the field.

A Cerenkov-ΔΕ-Cerenkov detector for high energy cosmic ray isotopes and an accelerator study of ^(40)Ar & ^(56)Fe fragmentation

This thesis has two major parts. The first part of the thesis will describe a high energy cosmic ray detector -- the High Energy Isotope Spectrometer Telescope (HEIST). HEIST is a large area (0.25 m²sr) balloon-borne isotope spectrometer designed to make high-resolution measurements of isotopes in the element range from neon to nickel (10 ≤ Z ≤ 28) at energies of about 2 GeV/nucleon. The instrument consists of a stack of 12 NaI(Tl) scintilla tors, two Cerenkov counters, and two plastic scintillators. Each of the 2-cm thick NaI disks is viewed by six 1.5-inch photomultipliers whose combined outputs measure the energy deposition in that layer. In addition, the six outputs from each disk are compared to determine the position at which incident nuclei traverse each layer to an accuracy of ~2 mm. The Cerenkov counters, which measure particle velocity, are each viewed by twelve 5-inch photomultipliers using light integration boxes.

HEIST-2 determines the mass of individual nuclei by measuring both the change in the Lorentz factor (Δγ) that results from traversing the NaI stack, and the energy loss (ΔΕ) in the stack. Since the total energy of an isotope is given by Ε = γM, the mass M can be determined by M = ΔΕ/Δγ. The instrument is designed to achieve a typical mass resolution of 0.2 amu.

The second part of this thesis presents an experimental measurement of the isotopic composition of the fragments from the breakup of high energy ⁴⁰Ar and ⁵⁶Fe nuclei. Cosmic ray composition studies rely heavily on semi-empirical estimates of the cross-sections for the nuclear fragmentation reactions which alter the composition during propagation through the interstellar medium. Experimentally measured yields of isotopes from the fragmentation of ⁴⁰Ar and ⁵⁶Fe are compared with calculated yields based on semi-empirical cross-section formulae. There are two sets of measurements. The first set of measurements, made at the Lawrence Berkeley Laboratory Bevalac using a beam of 287 MeV/nucleon ⁴⁰Ar incident on a CH₂ target, achieves excellent mass resolution (σ_m ≤ 0.2 amu) for isotopes of Mg through K using a Si(Li) detector telescope. The second set of measurements, also made at the Lawrence Berkeley Laboratory Bevalac, using a beam of 583 MeV/nucleon ⁵⁶FeFe incident on a CH₂ target, resolved Cr, Mn, and Fe fragments with a typical mass resolution of ~ 0.25 amu, through the use of the Heavy Isotope Spectrometer Telescope (HIST) which was later carried into space on ISEE-3 in 1978. The general agreement between calculation and experiment is good, but some significant differences are reported here.

Fibromialgia e dor: um estudo de caso sobre mal-estar no trabalho e adoecimento

A fibromialgia é uma síndrome reumática que atinge cerca de 2% da população brasileira, sendo 90% dos pacientes do gênero feminino. Os principais sintomas são dor crônica generalizada, depressão, desânimo e fadiga acentuada, provocando dificuldades sociais e afetivas cotidianas. Objetivo: O objetivo principal deste estudo foi apreender e interpretar sentidos e significados que mulheres com fibromialgia atribuem às práticas terapêuticas corporais realizadas no Projeto de Extensão: Tratamento Multidisciplinar para Pacientes Portadores de Fibromialgia realizado na Universidade do Estado do Rio de Janeiro (UERJ). Todas as mulheres foram diagnosticadas em ambulatórios públicos e privados e depois se inscreveram voluntariamente no tratamento gratuito disponibilizado. Nossa principal hipótese de estudo procura relacionar o adoecimento dessas mulheres com o regime social de trabalho, que aumenta o sofrimento e, por conseguinte, provoca somatização do mal-estar gerado. Métodos: Trata-se de um estudo socioantropológico com campo etnográfico, no qual foram observadas as práticas corporais semanais nos anos 2009-2010. Também foram realizadas fotografias e entrevistas em profundidade com todas as mulheres que participavam regularmente das práticas corporais. De igual modo, realizamos entrevistas por computador e por telefone com mulheres diagnosticadas por fibromialgia em diversas cidades brasileiras. Resultados: Foi possível compreender que estar em um local onde podem se relacionar com outras pessoas com os mesmos sinais e sintomas e que compartilhar situações de sofrimento semelhantes contribui para construção de uma identidade de grupo baseada no cuidado e no acolhimento. Assim, elas constroem coletivamente valores de cuidado com o corpo e com a saúde. Conclusões: A participação assídua no tratamento oferecido aumenta a qualidade de vida e a vitalidade de mulheres com fibromialgia, contribuindo para a promoção da saúde não apenas na sua dimensão físico-orgânica, mas em sua totalidade sócio-afetiva.
