Abstract: background: achievement of an ideal arterial substitute to be used in the reconstruction of small- and medium-caliber arteries is still the main objective of most scientific research studies developed in the area of vascular substitutes. sugarcane biopolymer membrane could be extremely useful to perform vascular reconstruction in arteries with diameter smaller than 4 mm, allowing treatment of diseases that affect millions of people in brazil and worldwide. objective: to evaluate the hemodynamic and histopathologic behavior of sugarcane biopolymer membrane when used as a patch in femoral artery angioplasty in dogs. method: eight adult mongrel dogs, under general anesthesia, underwent percutaneous doppler velocimetry of the left and right femoral arteries for preoperative control at the health sciences center experimental research laboratory of universidade federal de pernambuco. after being disinfected, the dogs underwent femoral artery patch angioplasty using a sugarcane membrane biopolymer patch on the left side and an expanded ptfe (e-ptfe) patch on the right side. the dogs underwent daily clinical evaluation for the first week and weekly thereafter. clinical evaluation consisted of an examination of femoral artery pulses, gait assessment and verification as to whether there was any pulsatile tumor, bruising, hemorrhage or surgical wound infection. one hundred and eighty days after the angioplasties, percutaneous doppler velocimetry of the femoral arteries was performed under general anesthesia. next, the dogs underwent dissection of the femoral arteries, measurement of the arterial diameter and perioperative doppler velocimetry proximally and distally to the artery angioplasty. laparotomy was then performed to expose the abdominal aorta for angiographic access. the femoral artery segments with patches were harvested for histopathologic analysis, and the animals were sacrificed under a toxic dosage of anesthetic. results: at 180 days, no cases of surgical wound in

Abstract: genetic variability was studied in five fish species (anostomidae): schizodon intermedius and s. nasutus and leporinus friderici, l. elongatus and l. obtusidens, collected at one location on the tibagi river (paraná, brazil). the protein data from seven systems coded collectively for 19 loci in the liver, muscle and heart. nine of these loci were polymorphic. the estimated proportion of polymorphism loci () varied from 16.7% in s. intermedius to 36.9% in l. friderici; the mean heterozygosity observed (o) was 0.027 ± 0.015 and 0.109 ± 0.042, respectively. the estimated value of the genetic identity among l. friderici and s. intermedius (0.749) and s. nasutus (0.787) suggested that these are "congeneric" species. morphological characteristics indicate that these species belong to distinct genera, while isoenzymatic data show that they are very similar at the genetic/biochemical level.

Report: Creative Labour and the Role of Intellectual Property
Ned Rossiter
Fibreculture Journal , 2003,
Abstract: This article reports on findings from a survey posted to the fibreculture mailing list prior to the 3rd annual fibreculture meeting in Brisbane this July. Broadly speaking, the survey was interested in the extent to which the exploitation of intellectual property defines the condition of labour within the creative industries. At a methodological level, the article challenges prevailing assumptions about conducting empirical research in new media studies and enlists a processual media theory approach as a technique for drawing out the relationships between the condition of creative labour and reflexive, non-linear media-information systems of communication. Central to this article is an argument about the merits of the Italian autonomist concept of 'immaterial labour' against what I term 'disorganised labour'. The article suggests that the latter more accurately describes the current condition of creative labour. The article concludes by advocating the political strategy of organising creative labour in the form of networks rather than the traditional model of the party, as adopted by various unions.
Rela??o entre emendas parlamentares e corrup??o municipal no Brasil: estudo dos relatórios do programa de fiscaliza??o da Controladoria-Geral da Uni?o

Abstract: previous studies on corruption (elliott, 2002; klitgaard, 1988; rose-ackerman, 2002) present the relationship between amendments and municipal corruption. four nonexclusive explanations for the correlation are discussed: (i) the growing potential gains of corruption; (ii) the number of transactions under the control of the local government; (iii) the pressure from groups of private rent-seekers and; (iv) revenue transfers might be the result of collusion between local governments and federal congressmen. using data from the controladoria-geral da uni?o (brazilian internal audit agency) anticorruption program based on the random auditing of municipal government's expenditures, we study the relationship between amendments to the brazilian federal budget law and municipal corruption. on average, after controlling for a series of socio-economic and political variables, cities granted with revenue transfers derived from amendments have corruption rates that are 25% higher than the rest of the sample. although our empirical results indicate that the increase in corruption occurs when the municipalities receive extraordinary revenue transfers, corruption seems to be insensitive to the amount of resources transferred. such findings give more support to explanations (iii) and (iv).

Abstract: Fossil groups are systems with one single central elliptical galaxy and an unusual lack of luminous galaxies in the inner regions. The standard explanation for the formation of these systems suggests that the lack of bright galaxies is due to galactic cannibalism. In this study we show the results of an optical and X-ray analysis of RX J1340.6+4018, the prototype fossil group. The data indicates that RX J1340.6+4018 is similar to clusters in almost every sense, dynamical mass, X-ray luminosity, M/L and luminosity function, except for the lack of L* galaxies. There are claims in the literature that fossil systems have a lack of small mass haloes, compared to predictions based on the LCDM scenario. The observational data gathered on this and other fossil groups so far offer no support to this idea. Analysis of the SN Ia/SN II ejecta ratio in the inner and outer regions shows a marginally significant central dominance of SN Ia material. This suggests that either the merger which originated the central galaxy was dry or the group has been formed at early epochs, although better data are needed to confirm this result.

Abstract: \"Is it possible to promote the construction of knowledge about phenotypic plasticity expressed by plants among elementary school students?” To answer this question, it was proposed to carry out experiments together with second year students of elementary school using the plant popularly known as Boldo Mirim (Plectranthus neochilus Schlechter). The objective of present study was to describe the results of the experiment performed on cuttings of Boldo Mirim raised in two types of soil [plant compost + poultry manure (3:1) or earthworm humus + bovine manure (1:1)], two types of light source (20 W lamp or sunshine) at four intensity (10%, 30%, 50%, or 100%). This experiment was attended by 21 children with ages ranging from 10 incomplete years to 10 years old. The positive experimental results showed how the light source and the nutritional richness of the soil are important determinants of plant survival and growth. The negative results involving absence of root development in plants under artificial lighting (20 W lamp) instigated the children to elaborate a hypothesis to be tested explaining this. The children’s drawings made after the planting and at the end of the experiments plus the answers obtained during group discussions revealed that they were able to build knowledge about the ability of plants to respond to environmental variables such as soil type and sunshine intensity, expressing phenotypic plasticity.

Abstract: this article presents an integrative review about studies that address the relationships between health professionals and users in health care practices. it aimed to identify aspects that were researched on the daily life of the services concerning such relationships. data were collected from the lilacs and pubmed databases based on these descriptors: user embracement; professionalfamily relations; professionalpatient relations; humanization of the care; and the bonding word associated to the single health system descriptor. two hundred and ninety studies, published from 1990 to 2010, were selected. through thematic analyses, five meaning cores were created: the relevance of the confidence in the professionaluser relationship; feelings and senses in the health care practice; the importance of communications in health care services; ways to organize health care practices and (de)colonialism. it was found that relationships established in health care practices have a transformative dimension. however, the challenge to humanize health care services remains. nursing stands out in the production of knowledge on such theme.
