Desmilitarização da polĂcia : um debate inadiĂĄvel sobre segurança pĂșblica
Monografia (graduação)âUniversidade de BrasĂlia, Faculdade de Direito, 2014.O modelo policial militarizado brasileiro se demonstra a cada dia como parte de um sistema de segurança pĂșblica falido. A partir da anĂĄlise da origem da polĂcia no Brasil, este trabalho traça um breve histĂłrico sobre a instituição atĂ© o perĂodo da redemocratização. Tendo em vista a cultura militarizada, sua extrema violĂȘncia e inoperĂąncia de resultados com custos elevados de gasto pĂșblico e perdas humanas, consequentes da atuação repressiva e autoritĂĄria das polĂcias militares, chega-se a contradição estrutural de manter uma polĂcia militarizada em um contexto de Estado DemocrĂĄtico de Direito. PropĂ”e-se, a partir da iniciativa e estudo da Proposto de Emenda Constitucional (PEC) 51, uma nova forma de organização policial de natureza civil, adequada aos movimentos da sociedade civil e atĂ© mesmo aos desejos dos corpos policiais, uma efetiva democratização da segurança pĂșblica e um perfil de polĂcia cidadĂŁ adequada aos nossos tempos. ____________________________________________________________________________ ABSTRACTThe Brazilian militarized police pattern has shown itself, throughout the time, as part of a flawed public security system. From the study of the inception of police in Brazil, a brief record will be made, in this paper, up to its democratization. Having seen the militarized culture, its extreme violence, as well as its lack of outcomes allied to high public expenses and human loss, as a result of the repressive and authoritarian performance of the Brazilian military police, we reach to the structural contravention of maintaining a militarized police in an ambience of Democratic Rule-of-law. From the initiative and study of the Proposed Constitutional Amendment (PCA) of number 51, in Brazil, we propose a reformulated approach to police organization of civil nature, suitable to the civil society and even to the volition of main police forces, coupled with an effective democratization of public security, and a profile of citizen police which meets the needs of the current times
Embolização das artérias uterinas: uma breve revisão de literatura / Embolization of uterine arteries: a brief review of Literature
Os miomas sĂŁo neoplasias benignas que apresentam tamanhos variados, subdividindo-se em submucoso, subseroso e intramural. Apresenta elevada taxa de incidĂȘncia em mulheres na idade fĂ©rtil, manifestando sintomatologia em cerca de 20 a 50% das pacientes. O tratamento pode ser clĂnico ou cirĂșrgico, sendo este Ășltimo realizado atravĂ©s de histerectomia, miomectomia ou embolização das artĂ©rias uterinas. Para a realização da pesquisa, foi realizada uma breve revisĂŁo de literatura acerca do uso da embolização para o tratamento de miomatose. A embolização independe do tipo de mioma, quantidade, localização e tamanho, sendo realizado o procedimento na grande maioria dos casos em ambas as artĂ©rias uterinas, pode ser realizado por cardiologistas e radiologistas intervencionistas. Os sintomas pĂłs-operatĂłrios mais comuns sĂŁo dor tipo cĂłlica, nĂĄuseas e vĂŽmitos. Em poucos dias a paciente retorna Ă s suas atividades normais, com um menor tempo de internação, sendo evidenciado na maioria das pacientes uma regularização do ciclomenstrual, com uma redução significativa do volume e duração da menstruação, alĂ©m do desaparecimento da dor e redução do volume uterino. O procedimento apresenta uma elevada taxa de sucesso, sendo assim considerada uma tĂ©cnica promissora e inovadora para pacientes que buscam procedimentos menos invasivos e preservação da fertilidade
Photography-based taxonomy is inadequate, unnecessary, and potentially harmful for biological sciences
The question whether taxonomic descriptions naming new animal species without type specimen(s) deposited in collections should be accepted for publication by scientific journals and allowed by the Code has already been discussed in Zootaxa (Dubois & NemĂ©sio 2007; Donegan 2008, 2009; NemĂ©sio 2009aâb; Dubois 2009; Gentile & Snell 2009; Minelli 2009; Cianferoni & Bartolozzi 2016; Amorim et al. 2016). This question was again raised in a letter supported
by 35 signatories published in the journal Nature (Pape et al. 2016) on 15 September 2016. On 25 September 2016, the following rebuttal (strictly limited to 300 words as per the editorial rules of Nature) was submitted to Nature, which on
18 October 2016 refused to publish it. As we think this problem is a very important one for zoological taxonomy, this text is published here exactly as submitted to Nature, followed by the list of the 493 taxonomists and collection-based
researchers who signed it in the short time span from 20 September to 6 October 2016
Global urban environmental change drives adaptation in white clover
Urbanization transforms environments in ways that alter biological evolution. We examined whether urban environmental change drives parallel evolution by sampling 110,019 white clover plants from 6169 populations in 160 cities globally. Plants were assayed for a Mendelian antiherbivore defense that also affects tolerance to abiotic stressors. Urban-rural gradients were associated with the evolution of clines in defense in 47% of cities throughout the world. Variation in the strength of clines was explained by environmental changes in drought stress and vegetation cover that varied among cities. Sequencing 2074 genomes from 26 cities revealed that the evolution of urban-rural clines was best explained by adaptive evolution, but the degree of parallel adaptation varied among cities. Our results demonstrate that urbanization leads to adaptation at a global scale
A computationally designed peptide derived from Escherichia coli as a potential drug template for antibacterial and antibiofilm therapies
Computer-aided screening of antimicrobial peptides (AMPs) is a promising approach for discovering novel therapies against multidrug-resistant bacterial infections. Here, we functionally and structurally characterized an Escherichia coli-derived AMP (EcDBS1R5) previously designed through pattern identification [α-helical set (KK[ILV](3)[AILV])], followed by sequence optimization. EcDBS1R5 inhibited the growth of Gram-negative and Gram-positive, susceptible and resistant bacterial strains at low doses (2 to 32 ΌM), with no cytotoxicity observed against non-cancerous and cancerous cell lines in the concentration range analysed
