História e memória da Revolu??o Farroupilha: breve genealogia do mito
Zalla, Jocelito;Menegat, Carla;
Revista Brasileira de História , 2011, DOI: 10.1590/S0102-01882011000200005
Abstract: the aim of this paper is to present a panorama of manifestations related to the farroupilha revolution, from the event itself to its consolidation as the founding myth of regional identity in rio grande do sul. debating important moments in this process, such as the refraction of memory in relation to the event, its political appropriation by the republican project, its rehabilitation in historical memory, and its ritualization in gaúcho traditionalism, it is proposed to analytically reconstitute the establishment of the fact as a symbolically cohesive and multiple heritage, sufficiently elastic to guide internal conflicts and tensions between the state and the center of brazil.
A crise da modernidade e a barbárie
Menegat, Marildo;
Physis: Revista de Saúde Coletiva , 2000, DOI: 10.1590/S0103-73312000000100009
Abstract: this essay intends to analyse the deadlocks in setting up the foundations of ethicity in modernity. it is based on the assumption that the classic authors of illuminism considered this problem a threat to the future of sociability. marx had the merit of having articulated this subject with the objective bases of the social structure. the twentieth century has witnessed the tragedy of this condition as destiny of mankind. grounded on adorno horkheimer's work, we intend to analyse the developments of this condition in the so-called post-modern culture. it defendes the hypothesis that the crisis of modernity, for lack of radical alternati ves that could overcome it, manifests itself as a slow emergence of barbarismo in a few words, not only the development of capitalism (and its cultural logic) produces barbarism, but also the barbarism is necessary for its continuity.
Eros?o real e estimada através da RUSLE em estradas florestais, em relevo ondulado a fortemente ondulado
Correa, Carla Maria Camargo;Cruz, Jocelito;
Revista árvore , 2010, DOI: 10.1590/S0100-67622010000400003
Abstract: the objective of this work was to evaluate the soil losses from a portion of forest roads located in a region with undulated to heavily undulated relief in two types of soil: humic cambissoil, typical dystrophic and red-yellow argissoil, typical dystrophic. the rainfall erosivity was calculated using rainfall data through the rigesa company, the soil erodibility was calculated based on the results of the analyses, the declivity and the slope length were measured in the field, and factors c and p were estimated from literature. the similarity hypothesis between the real values monitored over a one year period and the estimated values using the rusle were evidenced via statistical analyses that presented high correlations in the evaluated treatments, remaining inside the critical limit considered for the analyses, therefore validating the hypothesis.

Abstract: construction is one of the economic sectors that has the largest impact in the environmental. one of the main impacts caused by this activity is the large amount of waste that is generated, which is disposed irregularly in most brazilian municipalities, aggravating sanitation problems in urban areas. in order to address this problem, the federal government has undertaken some initiatives, including the creation of a resolution that establishes the development and implementation of an integrated waste management plan for the construction industry, based on the features of each region. the aim of this article is to present the results of a qualitative and quantitative assessment of the production of construction and demolition waste (cdw) in the municipality of pelotas, rs, carried out with the support of a computer software. the results indicated that 315.08 m3 of cdw are produced daily in the municipality, at a per capita generation rate of 1.23 kg/inhabitant per year. the density of cdw found was 1.28 ton/m3 and gravimetric composition showed that 88% of cdw produced was class a waste, which has a great potential for being reused and recycled.

Abstract: pea crop is a feasible option for agriculture in low lands during winter season. however, this crop is not adapted to extreme conditions of water deficit or excess. in hidromorfic soils, temporary waterlogging or flooding conditions often occur affecting directly plant growth. the effect of water level drawdown on the growth and yield of pea, cv axe, and the most sensitive growing stage of the crop to soil water excess were estimated. the effects of waterlogging and water table drawdown were proportional to flooding time, especially when waterlogging occurred at the vegetative stage. the major susceptibility of the pea plants to waterlogging was in reproductive stage, with significant yield reduction in all treatments. on the other hand, we observed that drawdown velocity had no effect on results, but on vegetative stage when a water level lowering in depths of more than 20 cm per day caused crop yield reductions of nearly 20%.

Abstract: the purpose of this study is a monthly assessment of fluoride levels in the public water supply in lages, santa catarina state, brazil. this town was divided into ten regions, where water samples were collected from october 2004 to september 2005. two samples were drawn from each region and sent to the fluoride health surveillance laboratory at vale do itajaí university for analysis through an electrometric method (orion 920a/orion electrode 9609). after twelve months, 120 samples had been collected, demonstrating gaps in the fluoride levels and some points with excessive fluoride levels (35,8%). several points with ideal fluoride concentrations (54.2%) also appeared. these findings lead to the conclusion that external controls are required for monitoring fluoride levels in the public water supply in lages.
The Botrychiopsis genus and its biostratigraphic implications in Southern Paraná Basin
Jasper, André;Guerra-Sommer, Margot;Cazzulo-Klepzig, Miriam;Menegat, Rualdo;
Anais da Academia Brasileira de Ciências , 2003, DOI: 10.1590/S0001-37652003000400009
Abstract: botrychiopsis has been considered an important floristic element of westphalian/artinskian associations of the paraná basin. the occurrence of botrychiopsis in roof-shales of the rio bonito formation in southern paraná basin (quitéria area), supported by the identification of botrychiopsis valida, enlarges the genus biochron. consequently, the stratigraphic hierarchy for botrychiopsis plantiana and botrychiopsis valida was defined for the paraná basin. although it is climatically controlled and related to a deglaciation icehouse stage, stratigraphic distribution of the genus presents a substantial climate tolerance, from cold/cool to warm/temperate conditions. a new phytostratigraphic zonation is proposed for the southern portion of the basin that includes the botrychiopsis zone (asselian/kungurian), which is subdivided into the botrychiopsis plantiana (asselian/artinskian) and botrychiopsis valida (late artinskian/kungurian) subzones.

Biotemas , 2011,
Abstract: This study verified spatial standards concerning freshwater mollusk trophic guild proportions, composition and distribution along the gradient of fluvial landscape units throughout the Velhaco stream, a subtropical stream located in Rio Grande do Sul state (Brazil). Quantitative collections (presence and absence) were made at six sampling stations distributed throughout the stream’s fluvial landscape units: Headspring Sector (SI), Proximal Intermediate Sector (SII), Distal Intermediate Sector (SIII), and Final Sector (SIV). Through the clustering (Jaccard coefficient, group linkage method of centroid) and Bray-Curtis polar ordination (similarity measure of Jaccard) analyses, a longitudinal species distribution pattern was verified within the gradients of the fluvial landscape units. Suspension feeders were dominant, except at SI. Species compositions at SI and SII (lower species richness) were related to their higher altitude, thicker sediments, greater oxygenation and higher pH. On the other hand, species compositions at SIII and SIV (higher species richness) were related to their larger hierarchical channel, larger width, larger depth, greater sinuosity, finer sediment and greater aquatic macrophyte richness. Contrary to the RCC predictions, the highest species number was not verified in the stream’s middle stretch, but in the end stretch.

PLOS ONE , 2013, DOI: 10.1371/journal.pone.0074280
Abstract: Methylated seed oil (MSO) is a recommended adjuvant for the newly registered herbicide topramezone in China and also in other countries of the world, but the mechanism of MSO enhancing topramezone efficacy is still not clear. Greenhouse and laboratory experiments were conducted to determine the effects of MSO on efficacy, solution property, droplet spread and evaporation, active ingredient deposition, foliar absorption and translocation of topramezone applied to giant foxtail (Setaria faberi Herrm.) and velvetleaf (Abutilon theophrasti Medic.). Experimental results showed that 0.3% MSO enhanced the efficacy of topramezone by 1.5-fold on giant foxtail and by 1.0-fold on velvetleaf. When this herbicide was mixed with MSO, its solution surface tension and leaf contact angle decreased significantly, its spread areas on weed leaf surfaces increased significantly, its wetting time was shortened on giant foxtail but not changed on velvetleaf, and less of its active ingredient crystal was observed on the treated weed leaf surfaces. MSO increased the absorption of topramezone by 68.9% for giant foxtail and by 45.9% for velvetleaf 24 hours after treatment. It also apparently promoted the translocation of this herbicide in these two weeds.
