Environmental factors influencing the distribution of three species within the genus Persephona Leach, 1817 (Crustacea, Decapoda, Leucosiidae) in two regions on the northern coast of Sao Paulo State, Brazil

Patterns of spatio-temporal distribution of Brachyura are determined by the interaction among life history traits, inter and intraspecific relationships, as well as by the variation of abiotic factors. This study aimed to characterize patterns of spatio-temporal distribution of Persephona lichtensteinii, Persephona mediterranea and Persephona punctata in two regions of the northern coast of Sao Paulo State, southeastern region of Brazil. Collections were done monthly from July 2001 to June 2003 in Caraguatatuba and Ubatuba, using a shrimp fishery boat equipped with double-rig nets. The patterns of species distribution were tested by means of redundancy analysis (RDA) and generalized linear mixed models (GLMM) in relation to the recorded environmental factors (BT: bottom temperature, BS: bottom salinity, OM: organic matter and granulometry (Phi)). The most influent environmental factor over the species distribution was the Phi, and the ascendant order of influence was P. lichtensteinii, P. punctata and P. mediterranea. The greater abundance of P. mediterranea showed a conservative pattern of distribution for the genus in the sampled region. The greater occurrence of P. punctata and P. lichtensteinii, in distinct transects than those occupied by P. mediterranea, seems to be a strategy to avoid competition among congeneric species, which is related to the substratum specificity.

Contribution in the diagnosis of ultrasonography perinephric pseudocyst uriniferous in a feline - case report

The renal pseudocysts are accumulations of fluid unilateral or bilateral perirenal location, contained in a capsule without epithelium, a characteristic that distinguishes them from true renal cysts. The capsule itself may have originated in the renal capsule or a localized inflammatory reaction. The nature of the fluid can vary, but the presence of ooze found the most common, but they are also called pseudocysts accumulations of urine, blood and lymph. The most frequently observed clinical sign is abdominal distention. However these nonspecific signs may be related to chronic kidney disease and azotemia that may develop before or after the formation of this lesion. The abdominal ultrasound is less invasive and allows you to diagnose this change more easily, also allowing the collection of fluid guided percutaneous and submit it to cytological, biochemical and bacteriological in order to obtain information about its nature. This paper aims to describe a case of perinephric pseudocyst in a cat uriniferous, highlighting the contribution ultrasound as a diagnostic method complementary quick and noninvasive, allowing evaluation of the architecture of the renal parenchyma, differentiation of cortex and spinal cord as well as detect changes in size and shape of it, aiming for better planning in clinical surgery.

Development and application of a screen-printed electrode modified with MWCNT for the electrocatalytic detection of thiram

Interest in the electronic properties of carbon nanotubes has increased in recent years. These materials can be used in the development of electrochemical sensors for the measurement and monitoring of analytes of environmental interest, such as pharmaceuticals, dyes, and pesticides. This work describes the use of homemade screen-printed electrodes modified with multi-walled carbon nanotubes (MWCNT) for the electrochemical detection of the fungicide thiram. The electrochemical characteristics of the proposed system were evaluated using cyclic voltammetry, with investigation of the electrochemical behavior of the sensor in the presence of the analyte, and estimation of electrochemical parameters including the diffusion coefficient, electron transfer coefficient (α), and number of electrons transferred in the catalytic electro-oxidation. The sensor response was optimized using amperometry. The best sensor performance was obtained in 0.1 mol L-1 phosphate buffer solution at pH 8.0, where a detection limit of 7.9 x 10-6 mol L-1 was achieved. Finally, in order to improve the sensitivity of the sensor, square wave voltammetry (SWV) was used for thiram quantification, instead of amperometry. Using SWV, a response range for thiram from 9.9 x 10-6 to 9.1 x 10-5 mol L-1 was obtained, with a sensitivity of 30948 µA mol L-1, and limits of detection and quantification of 1.6 x 10-6 and 5.4 x 10-6 mol L-1, respectively. The applicability of this efficient new alternative methodology for thiram detection was demonstrated using analyses of enriched soil samples.

Ontopolíticas e diagramas históricos do poder: maioria e minoria segundo Deleuze e a teoria das multidões segundo Peirce

This article aims at developing the so-called ontopolitics as G. Deleuze s innovative contribution to contemporary political philosophy. This objective will lead us to inspect the concept of power that Deleuze borrowed from Foucault and extended in order to assign to it an ontological adequacy. The concept of power opens access to another important element of the Deleuzean political philosophy, that is, the study of the historical diagrams of the power in the so-called discipline and control societies. With the combined dynamical diagram of both, we become aware of the portrait Deleuze draws for the democracy in contemporary societies. Digging into the Deleuzean ontopolitics, we will devote ourselves to the concepts of majority, minority and minor-becoming. It is in this point that the meeting between Deleuze s ontoplitics and Ch. Sanders Peirce s mathematical ontology becomes sound. It happens that Deleuze s ontopolitical concepts, besides their bond to an ontology of the power, receive also a mathematical treatment related to certain arithmetical (denumerable and nondenumerable) and geometrical notions (lines). The majorities and minorities are denumerable sets which are crossed by nondenumerable becomings. This step done, we will reach the stand point of the present paper, where we carry out initial approach with regard to an image for the concepts of majority and minority on the basis of Peirce s theory of collections and multitudes, mostly envisaging the mathematical ontology included in it. Accordingly, the main operation to be accomplished is that the Deleuzean distinction between the denumerable majorities/minorities and the nondenumerable mino-becoming may be mapped out in terms of discrete collections called enumerable, denumerable and abnumerable or postnumerable, in compliance with Peirce s terminology.

A new approach to the electronic structure of two dimensional disordered alloys

We propose a novel method to calculate the electronic Density of States (DOS) of a two dimensional disordered binary alloy. The method is highly reliable and numerically efficient, and Short Range Order (SRO) correlations can be included with no extra computational cost. The approach devised rests on one dimensional calculations and is applied to very long stripes of finite width, the bulk regime being achieved with a relatively small number of chains in the disordered case. Our approach is exact for the pure case and predicts the correct DOS structure in important limits, such as the segregated, random, and ordered alloy regimes. We also suggest important extensions of the present work. © 1995.

A review of pharmacokinetic parameters of metabolites and prodrugs

In drug discovery and development, the kinetic study of active metabolites plays an important role, helping to define the time course of the drug in the body and its activity or toxicity. After a pharmacokinetics assessment of a drug and its metabolite or a prodrug and its parent-drug, several parameters can be calculated. In some cases, achieving the objective of the study does not require all possible parameters to be calculated. When parameters are calculated, it is essential that their denotations are widely accepted and used. However, some parameters undergo a certain variability of denotation, which may confuse some readers. Thus, this review summarizes the current published data for experimental pharmacokinetic parameters of metabolites and the calculations involved in simple metabolite pharmacokinetic studies. It also evaluates the most common pharmacokinetic parameters in the literature and suggests metabolite parameters that could be determined to help advance metabolite kinetic models.

Modelling and determination of metabolic pools by stable carbon isotopes in the avian duodenal mucosa and albumen

Stable isotope analyses have helped in assessing dietary switches if the diet undergoes metabolic alteration (isotopic exchange). However, when considering the effects over time of switching from one diet to another, one can assess how quickly the new diet is incorporated into tissues via the isotopic renewal or incorporation rate, or turnover. Turnover is obtained using exponential curves that fit the original data, allowing the determination of practical order parameters such as the half-life (T) and the turnover constant (k). Researchers have found that metabolic incorporation can be fractionated. The resulting fractions, called metabolic pools, are identified using the linearization of the isotopic exchange model and its linear fit. This fractionation methodology is still not well defined. The objective of this study was to assess the behaviour of the metabolic renewal rate (turnover) in fractionated form, explain the theory, and apply it to data from the avian duodenal mucosa and albumen. We concluded that the duodenal mucosa has one metabolic pool, with a half-life of 1.23 days, and that the albumen has two metabolic pools, with half-lives of 1.89 and 6.32 days.
