Tatuagem, unheimliche e identificação: desvelamentos

The tattoo is a social phenomenon found in all social strata, with broad inclusion in all age groups and their motivation is commonly related to aesthetic pleasure, beauty and interest in body art. These references, however, are insufficient to understand the B side of the experience: the nightmares, attempts to erase, the compulsion and the concern about stop tattooing. Something happens between the search of beauty and the execution of the tattoo, that drags out the person to the anguish dimension. In detailing this, the specificity of distress Unheimliche will serve as our guide and, in the epistemological function of uncovering, allow an approximation to the concept of identification. Reading of the concept, the identification function will appear and, with it, the uncovering of the infinite pulse of desiring, when the object wants to talk,represent itself and manifest.The tattoos psychic function in the neurosis is the same for each step every morning: find the object and with this North, calibrate the compass of neurosis.

Os limites do corpo: modificações corporais

El cuerpo presenta rastros de la historia y cultura de las sociedades por toda la historia de la humanidad. El presente estudio quiere, através de pesquisas sobre el cuerpo, entender como las modificaiones corporales han acompañado la historia del hombre, de las tribus antiguas hasta la atualidad y como son hoy los procedimientos de cambiar la forma física. Através de trabajo de campo conocer profisionales que hacen algunos tipos de modificaciones corporales y gente que las tienen en sus cuerpos, entender las razones para que cambien sus cuerpos permanentemente - en la mayoria de los casos - y como la idea de individualidad surge cuando se hace una marca personal en el cuerpo. Además, compreender el porque esas prácticas se están convirtiendo cada vez mas común en nuestra sociedade actual

Synthetic and natural polycations for gene therapy: State of the art and new perspectives

Currently, the major drawback of gene therapy is the gene transfection rate. The two main types of vectors that. are used in gene therapy are based on viral or non-viral gene delivery systems. There are several non-viral systems that can be used to transfer foreign genetic material into the human body. In order to do so, the DNA to be transferred must escape the processes that affect the disposition of macromolecules. These processes include the interaction with blood components, vascular endothelial cells and uptake by the reticuloendothelial system. Furthermore, the degradation of therapeutic DNA by serum nucleases is also a potential obstacle for functional delivery to the target cell. Cationic polymers have a great potential for DNA complexation and may be useful as non-viral vectors for gene therapy applications. The objective of this review was to address the state of the art in gene therapy using synthetic and natural polycations and the latest strategies to improve the efficiency of gene transfer into the cell.

Predicting body and carcass characteristics of 2 broiler chicken strains using support vector regression and neural network models

As a new modeling method, support vector regression (SVR) has been regarded as the state-of-the-art technique for regression and approximation. In this study, the SVR models had been introduced and developed to predict body and carcass-related characteristics of 2 strains of broiler chicken. To evaluate the prediction ability of SVR models, we compared their performance with that of neural network (NN) models. Evaluation of the prediction accuracy of models was based on the R-2, MS error, and bias. The variables of interest as model output were BW, empty BW, carcass, breast, drumstick, thigh, and wing weight in 2 strains of Ross and Cobb chickens based on intake dietary nutrients, including ME (kcal/bird per week), CP, TSAA, and Lys, all as grams per bird per week. A data set composed of 64 measurements taken from each strain were used for this analysis, where 44 data lines were used for model training, whereas the remaining 20 lines were used to test the created models. The results of this study revealed that it is possible to satisfactorily estimate the BW and carcass parts of the broiler chickens via their dietary nutrient intake. Through statistical criteria used to evaluate the performance of the SVR and NN models, the overall results demonstrate that the discussed models can be effective for accurate prediction of the body and carcass-related characteristics investigated here. However, the SVR method achieved better accuracy and generalization than the NN method. This indicates that the new data mining technique (SVR model) can be used as an alternative modeling tool for NN models. However, further reevaluation of this algorithm in the future is suggested.
