title: Screening Indigenous Australia: Space, Place and Media in Frances Calvert's Talking Broken

description: Abstract Drawing on the fields of postcolonial studies and media theory, this article analyzes Frances Calvert's 1990 documentary, Talking Broken, which, inter alia, looks at the role of space, place and media amongst Australia's "other" Indigenous community, Torres Strait Islanders. The article explores the historical and geographical complexity of the space-place-media relation, particularly in terms of the centre-periphery relations between the Torres Strait and the Australian mainland, and considers the extent to which Calvert, after the Australian bicentenary of 1988, is able to absorb and playfully challenge such formulations. More broadly, it considers the extent to which contemporary Indigenous media might go further and enact a shift from absorbing and challenging such formulations to taking control of media institutions themselves.

title: Trajectory Control During an Aeroassisted Maneuver Between Coplanar Circular Orbits

description: ABSTRACT: This paper presents the simulation results of an aeroassisted maneuver around the Earth, between coplanar circular orbits, from a geostationary orbit to a low orbit. The simulator developed considers a reference trajectory and a trajectory perturbed by external disturbances combined with non-idealities of sensors and actuators. It is able to operate in closed loop, controlling the trajectory (drag-free control) at each instant of time using a Proportional-Integral-Derivative (PID) controller and propulsive jets. We adopted a spacecraft with a cubic body composed of two rectangular plates arranged perpendicular to the velocity vector of the vehicle. Propulsive jets are applied at the apogee of the transfer orbit in order to keep the perigee altitude and control the rate of heat transfer suffered by the vehicle during atmospheric passage. A PID controller is used to correct the deviation in the state vector and in the keplerian elements. The U.S. Standard Atmosphere is adopted as the atmospheric model. The results have shown that the aeroassisted transfer presents a smaller fuel consumption when compared to a Hohmann transfer or a bi-elliptic transfer.

title: CRUDE PROTEIN IN DIETS OF EUROPEAN QUAILS

description: Abstract The aim of this study was to evaluate crude protein (CP) levels for European quails from one to 14, 14 to 28 and 28 to 42 days old. The experiment was carried out in a completely randomized experimental design, with five treatments and five replications. No significant effects of CP levels on weight gain and feed conversion from 1 to 14 days were observed, however quails fed 26% CP diets had lower feed intake. The CP levels from 14 to 28 days had significant effect on feed intake, weight gain and feed conversion. Maximum weight gain and minimum feed conversion were estimated for quails fed 24% CP. The CP levels had a significant effect on the traits studied in the final phase, highest weight gain and lowest feed conversion were estimated for quails fed 23% CP. No significant effects of CP levels on hot and cold carcass weights, breast weight, and thigh and drumstick weight were observed. The crude protein requirements for European quails from 1 to 14, 14 to 28 days and 28 to 42 days old are 26, 24 and 23%, respectively, if the requirements of the first limiting amino acids are met.

title: ANALYSIS OF COSTS, REVENUES AND EQUILIBRIUM POINT OF THE CALVES PRODUCTION SYSTEMS IN RIO GRANDE DO SUL STATE

description: Abstract The aim of this study was the evaluation of the economic viability of a traditional model of beef calves production in extensive system, developed under the conditions of relevant receipts and input costs recommended for normal production conditions in the of Rio Grande do Sul state. There were two interviews in rural property for collection of data on the expenditure of resources, structures available for the system of production and occupancy rates of grazing areas. The results showed that major operating costs of the activity were the manpower and feeding the flock. In the land opportunity costs represented the largest proportion (52.0%) of the total cost. Fixed costs were higher variable costs (61.7% vs. 38.3%). Gross and net margins showed that the activity is sustainable but economically equilibrium point of calving (85.0%) was above average rates reported in the literature, and negative values for profitability (-19.0%) and profitability (-23.2%). It was concluded that the viability of production systems studied in this research can be obtained from the optimization of production technologies and the reduction of fixed costs without changing the recipes.

title: Sorghum (Sorghum bicolor) Pellet Production and Characterization

description: ABSTRACT Pelletization is a technique used to compact biomass, generating a granulated material called pellets, with high energy density. The objectives of this work were to produce pellets made from Sorghum (Sorghum bicolor) residuals and to evaluate its quality. Firstly, the residuals were characterized, followed by the production of the pellets. An experimental framework was adopted, entirely randomized with three treatments: T1 – 100% Sorghum, T2 – Sorghum + addition of wheat starch, and T3 – Sorghum with the addition of steam. There was also a comparison of the properties of the pellets with values determined by the European standard. It was concluded that Sorghum biomass (Sorghum bicolor) residuals are viable for pellet production; products obtained were homogenous and easy to handle; the treatment T1 presented the best results for pellet production; all treatments produced pellets within the specifications of the EN 14961-6 (DIN, 2012) standard for non-wood pellets.

title: DRY MATTER OBTAINIMENT METHOD AND CHEMICAL COMPOSITION OF ROUGHAGES

description: Abstract It was aimed determinate the influence of drying methods on nutritional composition of different roughages. The experimental material were four grass species (Urochloa brizantha cv. Marandu, Urochloa brizantha cv. MG4, Cynodon dactylon cv. Coastcross e Panicum maximum cv. Áries), one forage legume (Stylosanthes cv. Campo Grande) and two silages (Zea mays e Triticum aestivum cv. BRS Umbu). The drying methods were based on use of forced air oven or microwave oven. The experimental design were a 2 x 8 factorial arrangement (2 drying methods and 8 roughages) with 4 repetitions. There was no effect of drying method on roughages dry matter content. Microwave oven drying increased neutral detergent fiber. There was an interaction between drying method and evaluated roughage. Increased contents of crude protein (estilosante), neutral detergent insoluble nitrogen (Coastcross, MG4, Marandu e estilosante) and ether extract (MG4, estilosante e Áries) were observed when roughages were dried using microwave oven. The microwave oven usage is an alternative to obtain the dry matter content of roughages; however this technic may affect the sample composition.

title: Property tax: a tax adjustment methodology for Belo Horizonte/MG

description: Abstract The planning and municipal tax management in Brazil has experienced many different difficulties, including those affecting beyond own tax collection, as well the involvement of the population in defining the municipality budget policy. In many cases, the lack of accurate and detailed information is central to the failure of the policy tax of Brazilian municipalities. Given this situation, this paper proposes an adjustment methodology that estimates the disparity level and/or disproportionate tax burden of property tax in Belo Horizonte, based on the principles of tax equity and ability to pay, given by the level of average household income. The results show high regional disparity in the tax burden, considering the income and services in each census tract. While in Centro-Sul region there is a strong prevalence of underestimated tax collection, the census tracts located in the Norte, Venda Nova and Barreiro indicates predominance of tax reduction factors.

title: Hydric and Edaphic Influence on Floristic Composition in an Altered Riparian Area

description: ABSTRACT Alteration of a natural ecosystem can physically, chemically and biologically affect a determined area. Therefore, this study aimed to evaluate the relation between the hydrology, soils and vegetation existing in an area changed by the implantation of a Hydroeletric Power Plant (HPP) in the municipality of Roque Gonzales, Rio Grande do Sul state. The study area was composed of three samples located downstream of the dam. This analysis was performed by the points method to verify the existence of similarity patterns between the vegetation, inundation levels and edaphic soil characteristics of each sample. As a result, greater floristic similarity was observed between the species as a relation of the spatial location with inundation levels. Thus, we can conclude that the vegetal establishment in the study area is under the direct influence of waterflow variation levels from the HPP, which contributes to defining species adaptability to these specific conditions, among others.

title: Araucaria angustifolia Budding Techniques in Indoor and Outdoor Stablished Rootstocks

description: ABSTRACT The objective of this work was to evaluate the technical feasibility of budding in A. angustifolia in two rootstocks establishment, performed in two seasons of the year. In October and April, patch and flute budding techniques were carried on rootstocks kept indoor (greenhouse) and established outdoor (field), with grafts of adult female plants. The percentage of survival, percentage of shoots and number of shoots up to 300 days after budding (DAB) were evaluated. The patch budding performed in October showed the greatest grafts survival rates (82%) and percentage of shoots in the grafts (64%) at 180 DAB. The flute budding showed highest number of shoots (2.7 at 120 DAB and 3.5 at 180 DAB) when compared to patch budding. The use of the patch budding is recommended in spring, not requiring a controlled environment for the rootstocks. After 180 DAB there were no losses of grafted plants.

title: Production of Structural Particleboard of Mimosa Scabrella Benth With Lignin Phenol-formaldehyde Resin

description: ABSTRACT The objective of this work was to evaluate the feasibility of using lignin-phenol-formaldehyde resin in the production of Mimosa scabrella Benth (bracatinga) structural particleboard. The boards were produced with nominal specific mass of 0.75 and 0.95 g/cm3, 10% and 12% of phenol-formaldehyde and lignin-phenol-formaldehyde resins, with 10 and 12 min of pressing time. The boards quality was evaluated by means of the following physical-mechanical tests: specific mass, compression ratio, water absorption and thickness swelling after 2 and 24 hours soaking, perpendicular traction, static bending and screw pulling. Positive interactions of specific mass, resin content and pressing time were observed in the properties of the boards produced. The evaluation of the properties results based on the requirements of EN 312 (type P5) standard indicated the feasibility of using lignin-phenol-formaldehyde resin in the production of particleboard of Mimosa scabrellla for structural applications.

title: Microscopic evaluation of implant platform adaptation with UCLA-type abutments: in vitro study

description: Abstract Introduction The fit between abutment and implant is crucial to determine the longevity of implant-supported prostheses and the maintenance of peri-implant bones. Objective To evaluate the vertical misfit between different abutments in order to provide information to assist abutment selection. Material and method UCLA components (N=40) with anti-rotational system were divided as follows: components usinated in titanium (n=10) and plastic components cast proportionally in titanium (n=10), nickel-chromium-titanium-molybdenum (n=10) and nickel-chromium (n=10) alloys. All components were submitted to stereomicroscope analysis and were randomly selected for characterization by SEM. Result Data were analyzed using mean and standard deviation and subjected to ANOVA-one way, where the groups proved to statistically different (p=&lt;0.05), followed by Tukey’s test. Conclusion The selection of material influences the value of vertical misfit. The group machined in Ti showed the lowest value while the group cast in Ni Cr showed the highest value of vertical misfit.
