1. Aproximações entre governança colaborativa e ação comunicativa: uma proposta analítica de estudo
Resumo Pode-se dizer que os esforços do gerencialismo não conseguiram apresentar grandes mudanças nos padrões das relações entre Estado centralizador e sociedade. Com isso em vista, o objetivo desta pesquisa foi propor uma abordagem analítica, a partir das aproximações entre governança colaborativa (GC) e teoria da ação comunicativa (TAC), para i

2. Dumbbell Shaped Microstrip Broadband Antenna
Abstract In this article, a dumbbell shaped microstrip broadband microstrip antenna with partial ground plane is presented, The overall dimension of the proposed antenna is 20 × 15 × 1.5 mm3 and is fabricated on FR4 substrate which has electrical permittivity of 4.3 and loss tangent of 0.025. FR4 is a low cost and easily available. The thickness of the sub

3. Modification of Haessler’s sequential heuristic procedure for the one-dimensional cutting stock problem with setup cost
Abstract Paper aims We propose a modified Sequential Heuristic Procedure (MSHP) to reduce the cutting waste and number of setups for the One-Dimensional Cutting Stock Problem with Setup Cost. Originality This heuristic modifies Haessler’s sequential heuristic procedure (1975) by adapting the Integer Bounded Knapsack Problem to generate cutting patterns

4. A CPW-Fed Structure Shaped Substrate Wideband Microstrip Antenna for Wireless Applications
Abstract A structure shaped substrate wideband microstrip patch antenna fed by coplanar waveguide (CPW) is proposed for wireless applications. Structure shaped substrate is produced by cutting the rectangle shape substrate in the form of a semicircular disc. The radiating patch of proposed antenna is taken in the form of U-shape. The ground plane is extended

5. A GENETIC ALGORITHM FOR THE ONE-DIMENSIONAL CUTTING STOCK PROBLEM WITH SETUPS
This paper investigates the one-dimensional cutting stock problem considering two conflicting objective functions: minimization of both the number of objects and the number of different cutting patterns used. A new heuristic method based on the concepts of genetic algorithms is proposed to solve the problem. This heuristic is empirically analyzed by solving

6. Influence of core-finishing intervals on tensile strength of cast posts-and-cores luted with zinc phosphate cement
The core finishing of cast posts-and-cores after luting is routine in dental practice. However, the effects of the vibrations produced by the rotary cutting instruments over the luting cements are not well-documented. This study evaluated the influence of the time intervals that elapsed between the cementation and the core-finishing procedures on the tensile

7. Transcriptional networks reconstruction: identification of genes involved on cattle response to tick Rhipicephalus (Boophilus) microplus infestation.
In tropical countries, losses caused by tick infestation in cattle lead to a great impact on animal production systems. Weight and feed conversion reduction, together with diseases transmitted by the parasite are some of the problems that lead to economic losses of billion dollars a year. In a general way, Bos taurus indicus cattle are less susceptible to in

8. Algoritmos para problemas de corte e empacotamento / Algorithms for cutting and packing problems
Several versions of Cutting and Packing problems are considered NP-hard and, if we consider that P ¿ NP, we do not have any exact polynomial algorithm for solve them. Practical applications arises for such problems and include: resources allocation for computers; cut of steel, wood, glass, aluminum, etc.; packing of objects; and, loading objects into contai

9. Occurrence and genetic characterization of Listeria spp. in minimally processed vegetables commercialized in Porto Alegre, Brazil
Minimally processed vegetables go through many steps before they are refrigerated, selection, washing, peeling, cutting, disinfection and finally packaging. However, if no care is taken at the origin of the raw materials and in the processing stages, there is a chance of finding pathogenic bacteria, such as Listeria monocytogenes, which are able to grow at l

10. Seleção de novos tipos e propagação rápida em Solenostemon scutellarioides, Lamiaceae / Selection of new tipes and rapid propagation in Solenostemon Scutellarioides, Lamiaceae
The specie Solenostemon scutellarioides is an ornamental plant cultivated since the era Victoriana, very used due to great diversity of coloration, format of leaves and growth habits. However, the great instability of coloration and formats of these varieties have been hindering its commercial exploration. Two assays were conducted in the Experimental Statio

11. Desenvolvimento de alguns métodos de solução para o problema de redução de ciclos de serra / Development of some solution methods to the saw cycles reduction problem
In this work, the problem of reducing saw cycles is focused. This problem arises, for example, in cutting settings where the saw machine costs contributes significantly to production costs, and / or in a situation with high demand where the saw machine must be used efficiently, producing more items per unit of time. A new integer linear programming model is
