Numerical Study on Flow Field and Temperature Distribution in Growth Process of 200 mm Czochralski Silicon Crystals

The melt flow and temperature distribution in a 200 mm silicon Czochralski furnace with a cusp magnetic field was modeled and simulated by using a finite-volume based FLUTRAPP ( Fluid Flow and Transport Phenomena Program) code. The melt flow in the crucible was focused, which is a result of the competition of buoyancy, the centrifugal forces caused by the rotations of the crucible and crystal, the thermocapillary force on the free surfaces and the Lorentz force induced by the cusp magnetic field. The zonal method for radiative heat transfer was used in the growth chamber, which was confined by the crystal surface, melt surface, crucible, heat shield, and pull chamber. It was found that the cusp magnetic field could strength the dominant counter-rotating swirling flow cell in the crucible and reduce the flow oscillation and the pulling-rate fluctuation. The fluctuation of dopant and oxygen concentration in the growing crystal could thus be smoothed.

Diário da Constituinte [gravação de vídeo] : [programa n. 200]

Deputados de todos os partidos reuniram-se para discutir o sistema de governo. O Deputado Amaury Muller (PDT-RS) declara estar convencido de que é a sociedade que deve discutir esta questão, de tal forma que ela própria possa definir sua posição. O Deputado Marcelo Cordeiro (PMDB-BA) afirma que é preciso um novo regime político que assegure a maior participação do povo e a fiscalização dos atos do governo e que esse sistema é o parlamentarismo. O Deputado Victor Faccioni (PDS-RS) considera que o sistema parlamentar de governo é a mudança mais fundamental da Assembleia Nacional Constituinte (ANC). O Presidente do PMDB, Deputado Ulysses Guimarães reúne-se com o Presidente do PFL, o Senador Marco Marciel (PFL-PE) e demais líderes desses dois partidos. PFL e PMDB querem que a nova Constituição seja fruto do entendimento e o primeiro tema discutido foi o sistema de governo. Ulysses Guimarães (PMDB-SP) reconhece que há posições divergentes sobre o sistema de governo dentro dos próprios partidos e diz que é justo que se dê uma preferência para a decisão sobre esse assunto, na medida em que ele afeta toda a estrutura do projeto. Começam as Sessões Extraordinárias da Comissão de Sistematização para discutir as emendas populares. A primeira sessão contou com a participação de representantes da sociedade civil e a discussão girou em torno dos direitos da mulher, entre os quais o aborto foi o tema mais polêmico. A Deputada Abigail Feitosa (PMDB-BA) considera que o aborto deve ser matéria de lei ordinária. A Deputada Dirce Tutu Quadros (PTB-SP) defende que deva ser dado a mulher o direito de fazer ou não o aborto. Projeto de emenda popular, que concede aposentadoria às mulheres após 25 anos de serviço, ganhou o apoio do Relator da Constituição Bernardo Cabral e de muitos constituintes.

Un uso metafórico del vino en Aristófanes: las vinosas treguas de Acarnienses, 186-200

[ES] Aristófanes es un autor que muestra en sus obras una predilección especial por el vino, al que hace numerosas alusiones de todo tipo, relacionándolo con la celebración y la fiesta. Podemos destacar en particular algunos usos metafóricos en los que se muestra la estrecha relación que existe entre éste y la paz, con la que en cierta manera puede llegar a identificarse. Tal es el caso de un pasaje de Aristófanes (Acarnienses, 186-200) en el que las diversas propuestas de tregua se presentan como si fueran vinos de diversas añadas que el protagonista debe catar.

Radiotherapy plus nimotuzumab or placebo in the treatment of high grade glioma patients: results from a randomized, double blind trial

Background The prognosis of patients bearing high grade glioma remains dismal. Epidermal Growth Factor Receptor (EGFR) is well validated as a primary contributor of glioma initiation and progression. Nimotuzumab is a humanized monoclonal antibody that recognizes the EGFR extracellular domain and reaches Central Nervous System tumors, in nonclinical and clinical setting. While it has similar activity when compared to other anti-EGFR antibodies, it does not induce skin toxicity or hypomagnesemia. Methods A randomized, double blind, multicentric clinical trial was conducted in high grade glioma patients (41 anaplastic astrocytoma and 29 glioblastoma multiforme) that received radiotherapy plus nimotuzumab or placebo. Treatment and placebo groups were well-balanced for the most important prognostic variables. Patients received 6 weekly doses of 200 mg nimotuzumab or placebo together with irradiation as induction therapy. Maintenance treatment was given for 1 year with subsequent doses administered every 3 weeks. The objectives of this study were to assess the comparative overall survival, progression free survival, response rate, immunogenicity and safety. Results The median cumulative dose was 3200 mg of nimotuzumab given over a median number of 16 doses. The combination of nimotuzumab and RT was well-tolerated. The most prevalent related adverse reactions included nausea, fever, tremors, anorexia and hepatic test alteration. No anti-idiotypic response was detected, confirming the antibody low immunogenicity. The mean and median survival time for subjects treated with nimotuzumab was 31.06 and 17.76 vs. 21.07 and 12.63 months for the control group. Conclusions In this randomized trial, nimotuzumab showed an excellent safety profile and significant survival benefit in combination with irradiation.

Relationship between fish size and otolith length for 63 species of fishes from the Eastern North Pacific Ocean

Otoliths commonly are used to determine the taxon, age, and size of fishes. This information is useful for population management, predator-prey studies, and archaeological research. The relationship between the length of a fish and the length of its otoliths remains unknown for many species of marine fishes in the Pacific Ocean. Therefore, the relationships between fish length and fish weight, and between otolith length and fish length, were developed for 63 species of fishes caught in the eastern North Pacific Ocean. We also summarized similar relationships for 46 eastern North Pacific fish species reported in the literature. The relationship between fish length and otolith length was linear, and most of the variability was explained by a simple least-squares regression (r 2 > 0.700 for 45 of 63 species). The relationship between otolith length and fish length was not significantly different between left and right otoliths for all but one fish species. Images of otoliths from 77 taxa are included to assist in the identification of species. (PDF file contains 38 pages.)
