Quando o Legislativo não legisla : o caso do Projeto de Lei nº 1.151/1995, que disciplina a união civil entre pessoas do mesmo sexo

Analisa as repercussões sociais e os sucedâneos jurídicos à falta de regulamentação em lei de usos e costumes, já incorporados ao "modus vivendi" da sociedade, de populações de orientação minoritária. Descreve e analisa os debates travados em torno do Projeto de Lei nº 1.151/1995 que trata da união civil homossexual e da criação do instrumento legal intitulado parceria civil registrada.

União civil entre pessoas do mesmo sexo : considerações acerca da não deliberação do Projeto de Lei n. 1.151/1995

Estudo de caso sobre o Projeto de Lei n. 1.151/1995, de autoria da deputada Marta Suplicy, que trata da união civil entre pessoas do mesmo sexo.

The changes in various iron compounds in culture media for algae. [Translation from: Archiv fur Hydrobiologie Supplemente Band 38(1/2) 151-169, 1970.]

The purpose of this work is a contribution to the quantitative record of the use of iron by planktonic algae. Preliminary experiments with Chlorella to determine the rate of iron intake in the presence of inorganic sources of iron did not produce the desired result. The crucial point of this work is the investigation of the influence of various external factors on the stability of FeEDTA (FeEDTA = Ferric(III)-compound of ethylene-diamine tetra-acetic acid), since this compound appears to be particularly well-suited as a source of iron for planktonic algae (e.g. TAMIYA et al. 1953). Cultures of Chlorella fusca in a light thermostat were used in experimental research. Methods and results are discussed.

Eudiaptomus vulgaris Schmeil is the most abundant copepod in Lake Maggiore and forms also, in respect to other entomostraca, the most important element, through its average biomass and because it is fairly numerous throughout the year. Plankton samples collected in a systematic and quantitative way, gave the opportunity to study some aspects of the dynamics of the population of this copepod, in safety in view of the uncertainty which in this kind of study can ensue when samples are taken only at a single station - in consequence of the changes in size of population between different water masses. The results of the biometrical observations are of the population of Eudiaptomus vulgaris is presented.

Low threshold amplified spontaneous emission based on coumarin 151 encapsulated in mesoporous SBA-15

Amplified spontaneous emission (ASE) characteristics of a blue dye coumarin 151 encapsulated in a highly ordered mesoporous SBA-15 were studied. The spectra narrowing was observed and found that the threshold and loss were greatly reduced, and the gain is significantly increased compared with spin-coated coumarin 151 doped poly(4-vinylphenol) film. The ASE threshold, gain, and loss, respectively, reached 0.55 mJ pulse(-1) cm(-2), 44.78 cm(-1), and 8.9 cm(-1) for the coumarin 151 encapsulated in mesoporous SBA-15 film. The optimized lasing action owes much to the effects of the better spatial confinement of the molecules in the ordered mesoporous structure of the host SBA-15.

A METHOD OF FITTING TO MOSSBAUER SPECTRUM OF EU-151 AND ITS APPLICATION TO EUROPIUM COMPOUNDS

A method of fitting to Mossbauer spectrum of 151Eu has been proposed. The intensities and the positions of all the possible transitions between the sublevels of the ground state and those of the excited state of nucleus with spin I> 3/2 can be considered at one time in fitting to experimental Mossbauer spectra by this method. The method has been used to fit to the experimental Mossbauer spectra of europium orthophosphate crystal and of europium pentaphosphate crystal, and to derive Mossbauer parameters from...

一种拟合~(151)Eu穆斯堡尔谱的方法及其对铕化合物的应用

本文提出了一种拟合~(151)Eu的穆斯堡尔谱的计算方法。用这种方法拟合~(151)Eu(I>3/2)的实验穆斯堡尔谱时,可以同时对所有可能跃迁线的位置和相对强度进行拟合。我们用这种方法对EuPO_4晶体和EuPsO_(14)晶体的穆斯堡尔谱进行了拟合,得到了相应的穆斯堡尔参数。对方法及拟合的结果也进行了讨论。
