Germinação de sementes e emergência de plântulas de Oenocarpus minor Mart. (Arecaceae)

O presente trabalho teve como objetivo avaliar a influência da temperatura e do substrato na germinação, bem como determinar a profundidade ideal de semeadura para emergência de plântulas de Oenocarpus minor Mart. Utilizou-se o delineamento experimental inteiramente casualizado, em esquema fatorial 3x4 (temperatura x substrato), com três repetições de 30 sementes cada. As sementes foram colocadas no interior de caixas plásticas contendo substrato umedecido com água destilada e mantidas em câmaras de germinação à temperatura constante e com fotoperíodo de 12 horas. Para a emergência, foram usadas 4 repetições de 24 sementes, distribuídas em bandeja plásticas, com plantmax e vermiculita, em 0; 2 e 4 cm de profundidade de semeadura, mantidas em casa de vegetação. Baseado nos resultados obtidos, os substratos mais adequados para a germinação de sementes foram a areia e a vermiculita, e a melhor temperatura foi a de 30ºC. Profundidade superior a 2 cm é inadequada para a semeadura de Oenocarpus minor Mart.

A investigação criminal e a vedação ao anonimato no sistema jurídico brasileiro

The thesis, prepared with basis on deductive reasoning (through the utilization of general concepts of the fundamental rights theory) and on inductive logic (by means of the consideration of particular situations in which the theme has been approached) deals with the criminal investigation and the prohibition of anonymity in the Brazilian law system. The state criminal investigation activity presents not only a substantial constitutional basis, due to the objective dimension of fundamental rights (which imposes an obligation to protect these essential values), but also a formal constitutional basis, arising from the administrative principles of rule of law, morality and efficiency, referred to in article 37 of the Constitution. The criminal investigation, however, is not an unlimited pursuit, being restrained by the duty to consider fundamental rights that oppose to its realization. One of the limits of the state investigation activity, in the Brazilian law system, is the prohibition of anonymity, referred to in article 5°, IV, of the Constitution. This prohibition is a direct constitutional restriction to the freedom of expression that aims to ensure the credibility of the diffusion of ideas and prevent the abusive exercise of this fundamental right, which could harm both persons and the state, with no possibility of punishment to the offending party. Generally, based on this prohibition, it is affirmed that a criminal investigation cannot begin and progress founded on anonymous communication of crimes. Informations about crimes to the investigative authorities require the correct identification of the stakeholders. Therefore, it is sustained that the prohibition of anonymity also comprehends the prohibition of utilization of pseudonyms and heteronyms. The main purpose of this essay is to recognize the limits and possibilities in starting and conducting criminal investigations based on communication of crimes made by unidentified persons, behind the veil of anonymity or hidden by pseudonyms or heteronyms. Although the prohibition of article 5°, IV, of the Constitution is not submitted to direct or indirect constitutional restrictions, this impediment can be object of mitigation in certain cases, in attention to the constitutional values that support state investigation. The pertinence analysis of the restrictions to the constitutional anonymity prohibition must consider the proportionality, integrated by the partial elements of adequacy, necessity and strict sense proportionality. The criminal investigation is a means to achieve a purpose, the protection of fundamental rights, because the disclosure of facts, through the investigatory activity, gives rise to the accomplishment of measures in order to prevent or punish the violations eventually verified. So, the start and the development of the state criminal investigation activity, based on a crime communication carried out by an unidentified person, will depend on the demonstration that the setting up and continuity of an investigation procedure, in each case, are an adequate, necessary and (in a strict sense) proportional means to the protection of fundamental rights

A responsabilização criminal no estado democrático de direito: o equilíbrio entre a efetividade e os limites da pretensão punitiva da sociedade

This paper analyzes the relationship between fundamental rights and the exercise of the claim punitive society in a democratic state. It starts with the premise that there are fundamental rights that limit and determine the validity of all forms of manifestation of the claim punitive society (legislating, investigative, adjudicative or ministerial) and there are others that require the state the right exercise, fast and effective of these activities. Travels to history in order to see that the first meaning of these rights was built between the seventeenth and eighteenth centuries, after all a history of abuses committed by state agents in the exercise of criminal justice, and positively valued in the declarations of human rights and proclaimed in the constitutions after the American and French Revolutions, while the second meaning has been assigned between the nineteenth and twentieth centuries, when, because of the serious social problems generated largely by absenteeism state, it was noted that in addition to subjective rights the individual against the state, fundamental rights are also objective values, which trigger an order directed the state to protect them against the action of the offending individuals themselves (duty to protect), the mission of which the State seeks to discharge, among other means, through the issue of legal rules typifying the behavior detrimental to such rights, subject to penalties, and the concrete actions of public institutions created by the Constitution to operate penal law. Under this double bias, it is argued that the rule violates the Constitution in the exercise of the claim punitive society as much as by excess malfere fundamental rights that limit, as when it allows facts wrong by offending fundamental rights, remain unpunished either by inaction or by insufficient measures taken abstractly or concretely provided

Paulo Egídio e a sociologia criminal em São Paulo

Este artigo discute a trajetória intelectual e política de Paulo Egídio. Autor praticamente esquecido pelos trabalhos que reconstituem a história do pensamento social no Brasil, Paulo Egídio foi um importante divulgador da sociologia entre o final do século XIX e o início do século XX em São Paulo, tendo produzido uma obra pioneira sobre Durkheim e desenvolvido cursos livres da disciplina. O artigo busca também apresentar alguns aspectos de sua atividade política como senador nos primeiros momentos da República, quando teve destacada participação no debate sobre a criação de uma rede de instituições de controle social e, em particular, sobre a construção de uma nova penitenciária para o estado de São Paulo.

Changes in minor salivary glands during 4-nitroquinoline 1-oxide-induced rat tongue carcinogenesis

We investigated the changes of minor salivary glands during 4NQO-induced rat tongue carcinogenesis. Histopathological examinations of serous and mucous tongue salivary glands of 30 male Wistar rats were performed after 4, 12 and 20 weeks of 50 ppm 4NQO chronicle administration in drinking water. Ten rats were used as control. Morphometric results were expressed as volume density (Vv %) of each of the components. Histopathological and morphometric changes in the salivary glands were evident only at 20 weeks following 4NQO administration and they included a significant (P < 0.05) decreased in the mean Vv of the serous acini compared with the control group accompanied by abnormal acini (Vv=14 %). Neither mucous acini nor ducts demonstrated significant changes. In conclusion, minor salivary glands are involved in the progression of 4NQO-induced carcinoma.

Production, purification and characterization of a minor form of xylanase from Aspergillus versicolor

A strain of Aspergillus versicolor produces a xylanolytic complex containing two components, the minor component being designated xylanase II. The highest production of xylanase II was observed in cultures grown for 5 days in 1% wheat bran as carbon source, at pH 6.5. Xylanase II was purified 28-fold by DEAE-Sephadex and HPLC GF-5 10 gel filtration. Xylanase II was a monomeric glycoprotein, exhibiting a molecular mass of 32 kDa with 14.1% of carbohydrate content. Optimal pH and temperature values for the enzyme activity were about 6.0-7.0 and 55 degreesC, respectively. Xylanase II thermoinactivation at 50degreesC showed a biphasic curve. The ions Hg2+, Cu2+ and the detergent SDS were strong inhibitors, while Mn2+ ions and dithiothreitol were stimulators of the enzyme activity. The enzyme was specific for xylans, showing higher specific activity on birchwood xylan. The Michaelis-Menten constant (K-m) for birchwood xylan was estimated to be 2.3 mg ml(-1) while maximal velocity (V-max) was 233.1 mumol mg(-1) min(-1) of protein. The hydrolysis of oat spell xylan released only xylooligosaccharides. Published by Elsevier Ltd.

Immunohistochemical study of acinic cell carcinoma of minor salivary gland

Acinic cell carcinoma (ACC) is a rare salivary gland tumour, making up 4% of all minor salivary gland tumours. Typically, it is composed of acinic cells although transitional and duct-like cells are also identified. In the present study, a panel of antibodies was applied to eight minor salivary gland ACCs. Antibodies tested were: cytokeratins 7, 8, 13, 14, 18, 19, vimentin and actin (HHF35). Immunohistochemical staining revealed that cytokeratin 8, among the tested antibodies, was the more specific to neoplastic cells with a pattern of distribution quite variable and peculiar. This staining may be useful in the recognition of neoplastic acinic cells. (C) 1997 Elsevier B.V. Ltd.
