Showing the destination of hypertext links: a new approach for Guide

All hypertext systems have a kind of button which can be selected interactively by the user to obtain further information. This paper is concerned with how to show the user the further information when the button is selected. We comment how several hypertext systems show this information, describe in detail how the Guide system currently does it and propose two alternative new approaches

Searching for Elko dark matter spinors at the CERN LHC

The aim of this work is to explore the possibility to discover a fermionic field with mass dimension one, the Elko field, in the Large Hadron Collider (LHC). Due to its mass dimension, an Elko can only interact either with Standard Model (SM) spinors and gauge fields at 1-loop order or at tree level through a quartic interaction with the Higgs field. In this Higgs portal scenario, the Elko is a viable candidate to a dark matter constituent which has been shown to be compatible with relic abundance measurements from WMAP and direct dark matter--nucleon searches. We propose a search strategy for this dark matter candidate in the channel $pp \rightarrow l^+ l^- + \not\!\! E_T$ at the $\sqrt{s}=14$ TeV LHC. We show the LHC potential to discover the Elko considering a triple Higgs-Elko coupling as small as $\sim 0.5$ after 1 pb$^{-1}$ of integrated luminosity. Some phenomenological consequences of this new particle and its collider signatures are also discussed.Comment: 7 pages, 3 figure

Strategic knowledge management : a conceptual model proposal

Buscando caracterizar a Gestão do Conhecimento Estratégico – GCE, este artigo visa apresentar os resultados parciais do estudo teórico que compreende, entre outros objetivos, o estabelecimento de um modelo conceitual para a gestão desse tipo de conhecimento. A metodologia envolveu a pesquisa bibliográfica de autores nacionais (entre eles, Terra e Teixeira Filho) e internacionais (Nonaka, Takeuchi, Davenport, Prusak e outros), que definiram modelos de Gestão do Conhecimento – GC, levando em consideração o tratamento do conhecimento tácito. Ampliou-se o estudo comparando tais modelos com as Teorias da Administração que assinalam as diferentes formas de tratamento da estratégia – perspectivas clássica, evolucionária, processual, sistêmica e do conhecimento – além de focar os aspectos cognitivos da tomada de decisão e da formulação estratégica. Valendo-se do raciocínio abdutivo, obteve-se como resultado uma proposta modelo de Gestão do Conhecimento Estratégico – GCE, para o qual são indicados os elementos participantes da visão geral da GCE, bem como os fatores intervenientes em programas de implantação e desenvolvimento desse tipo de GC. ___________________________________________________________________________________ ABSTRACTStudy tries to characterize Strategic Knowledge Management – SKM and presents the partial results of a theoretical research. The objectives of the research include the establishment of a conceptual model to this kind of knowledge. The Methodology included a bibliographic research of the Brazilian (Terra, Teixeira Filho and others) and foreign authors (Nonaka, Takeuchi, Davenport, Prusak etc.) which treat Knowledge Management focusing the tacit knowledge. It was used the comparative method to analyze different types of Knowledge Management – KM models with the different perspectives of strategy – classic, evolutionary, process, systemic and knowledge – besides take some concepts of cognitive psychology that interfere on the strategic formulation and strategic decision making. Using the abductive method, the results indicate the fundamental elements of an overview of Strategic Knowledge Management – SKM, as well as the intervenient factors in programs to implantation and development this kind of KM

Efeito do habitat na fecundidade das fêmeas, sobrevivência e razão sexual dos jovens de jacarés-do-pantanal.

A fecundidade das fêmeas, sobrevivência dos ovos e a razão sexual dos filhotes recém-eclodidos de Caiman crocodilus yacare foram estudados nas fazenda Nhumirim (área de lagos) e Campo Dora (área de rios intermitentes) no Pantanal. As fêmeas reprodutivas foram maiores na área de rios intermitentes do que na área de lagos. O número médio de ovos foi de 22,5 (DP = 3,69) na área de lagos e 29,8 (DP= 5,95) na área de rios intermitentes. As fêmeas maiores produziram mais ovos independente da área. A inundação e a predação causaram morte dos ovos do jacaré-do-Pantanal. A predação foi alta em ninhos de floresta, mas a presença da equipe de pesquisa pode ter contribuído para aumentar a predação nesses locais. O período de determinação do sexo pode estender-se até os primeiros 40 dias de incubação. As percentagens de machos estimados em ninhos de vegetação flutuante variaram entre os dois anos, mas não variaram nos ninhos de floresta. As temperaturas de incubação afetaram o comprimento dos filhotes. No manejo dos caimans devem ser consideradas as diferenças dos habitats.bitstream/item/37409/1/BP42.pd

Effects of Mitomycin C in Early Conjunctival Inflammation after Pterygium Surgery

Purpose: The purpose of this study was to compare inflammatory events and graft characteristics 1 month and 6 months after conjunctival limbal autograft (CLAU) with and without intraoperative mitomycin C (MMC). Methods: This study included 69 eyes of 69 patient’s eyes with pterygium. Clinical data concerning patient demography, preoperative examination including pterygium morphology, recurrence clinical assessment, and complications after CLAU with (MMC+) and without (MMC-) intraoperative MMC were all registered at 1 month and 6 months after surgery. Results: Thirty-five eyes were included in MMC+ and 34 in MMC-. Preoperative data were similar in both groups (Student’s t test and Fisher’s exact test; p > 0.05). Thirty-four (49.6%) eyes in the whole sample showed at least one inflammatory complication at 1 month after surgery. MMC- group showed a significantly higher number of cases with complications (p 0.05; Chi2 test). Pyogenic granuloma developed at the surgical site in three eyes (4.37%), two of those granulomas were at the MMC- group (p > 0.05). Tendency for recurrences was significantly different between both groups (p = 0.0001; Fisher’s exact test) at the end of 6 months. Thirteen (38%) eyes showed recurrence in MMC- and no cases were displayed in MMC+. Presence of at least 1 inflammatory event was only seen in 16 (23%) cases, all of them in MMC-. Specifically, 15 (44%) eyes showed hyperemia and one (3%) eye presented conjunctival hemorrhages. No new cases of pyogenic granuloma or graft contraction were seen at this time point in both groups. Hyperemia was the only specific event with significant differences between MMC- and MMC+ (p = 0.0001; Fisher’s exact test) at 6 months after surgery. Conclusion: The eyes receiving intraoperative MMC after CLAU seem to present less hyperemia and graft contraction after surgery than those that did not receive MMC as an adjuvant factor. Intraoperative MMC could be associated with a lower recurrence rates.Postprint (author's final draft
