title: Wastewater treatment using adsorption process in column for agricultural purposes

description: Abstract Water is essential for life, important for the ecosystem and it is in great demand due to its scarcity. This study explored the reuse of the wastewater of the Water Treatment Plant in Gramame for agricultural purposes. A qualitative and quantitative investigation of the effluent was carried out through the characterization of its physical and chemical parameters, comparing the results to what is allowed by the current legislation, CONAMA Resolution 357/2005. After this process, the activated charcoal of coco-da-baia mesocarp, adsorbent material, was prepared and tested in a filter system in a column with a continuous flow and ascendant entrance, in which the kinetic effect was evaluated. This technique was evaluated by correlating the reduced values in the adsorption material, respecting the initial effluent concentration, obtaining a reduction of 50% in the hardness, 87.5% in chloride and 66.6% in acidity. These results verified the adequacy of the technique in potential hydrogenation (pH) and abrupt reduction of color and turbidity. This treatment is suggested to qualify the effluent for use in agricultural, safe for humans and the environment. The adsorbent substrate efficiency was verified by correlating it with the Thomas isothermal model.

title: Quantification study of Azithromycin drugs in soil, by the infrared technique with Fourier Transform (IFTR)

description: Abstract Some classes of drugs represent greater criticality as environmental contamination; antibiotics in general represent the most potent contaminants and cause greater damage to the environment. The purpose of this work is to quantify the percentage of soil contamination by Azithromycin in presentations of 500 mg, through the application of Infrared Spectroscopy with Fourier Transform. It was verified that the drug exerts significant impacts to the environment, even in the characteristic of micropollutant, and that its extraction when performed with Pure Acetonitrile allows its residues in soil samples to be satisfactorily quantified.

title: Losses of soil, water, organic carbon and nutrients caused by water erosion in different crops and natural savannah in the northern Amazon

description: Abstract Currently in Brazil, the main form of erosion is caused by the impact of raindrops on the soil surface, triggering the process of water erosion and causing serious damage to agricultural areas. This study evaluated losses of soil, water, organic carbon and nutrients in different cultures, bare soil and savanna under natural rain. The experimental design was completely randomized with five treatments (bare soil - BS, cowpea bean - CB, Brachiaria brizantha - BB, corn - CO and natural savanna - SN) with three replications; The treatment of bare soil (BS), followed by the treatment cultivated with cowpea bean (CB) showed higher losses of soil, water, organic carbon and nutrients; The highest losses of soil, water, organic carbon and nutrients in the treatment of bare soil (BS) occurred during the period of greatest erosivity; but for treatments CB, BB and CO, the highest losses occurred during the establishment of the crop, in view of the lower soil cover. Soils cultivated with Brachiaria brizantha - BB, corn - CO and in the Natural Savana - SN area were more efficient in reducing soil and water losses during all months evaluated. Plant cover produced by the (SN) treatment and by the (BB) and (CO) treatments acted to reduce the harmful effects of erosion, minimizing losses of nutrients and organic carbon. The soil should be well protected during periods when rainfall presents the highest values of erosivity index.

title: Assessment of digital elevation models to obtain morphometric characteristics in relief transition region

description: Abstract The purpose of this study was to evaluate the performance of Digital Elevation Models (DEMs) in the morphometric characterization of a basin located in a transitional region between the São Francisco Plateau, São Francisco Depression and Espinhaço Range reliefs. For the study, four DEMs were generated by interpolation of the SRTM data and topographic maps, using the Topo To Raster interpolator with and without mapped hydrography support, available in ArcGIS® 9.3 software. Another DEM was obtained from the SRTM original data. From the generated DEMs, the morphometric characteristics of the basin were determined and compared to those obtained from topographic maps, denominated reference (REF), by means of percentage errors. The evaluation was also performed in a qualitative way, comparing the drainage and the basin delineations. In general, the DEMs obtained with the support of the mapped hydrography (SRTM-TRH and CT-TRH) provided the best results, with small errors, mainly for the main morphometric characteristics of the basin, drainage area and main river length, which ranged from 0.38 to 1.12% and 5.28 to 7.07%, respectively. On the other hand, the DEMs generated without the support of the mapped hydrography (SRTM-O, SRTM-TR and CT-TR) presented major errors mainly in determining the drainage area and length of the main river, which varied from 18.1 to 26.6% and 26.7 to 34.4%, respectively. These occurred due to a deviation of the main river in the São Franciscana Depression region, which allows us to conclude on the necessity and importance of evaluating DEMs before their use.

title: Intercurrence between enzootic leukosis and tuberculosis in slaughtered bovine in slaughterhouses

description: ABSTRACT: Leukosis and tuberculosis are diseases that affect cattle and entail considerable economic losses, due to theim pact on productivity, but there are few reports that they occur simultaneously. Therefore, aimed to evaluate the complications of these diseases in cattles laughtered in São Gotardo, MG, these animals were positive to the tuberculin and showed lesions characteristic of the disease during the stamping. One hundred and thirty three samples of blood serum, all from positive to bovine tuberculosis, were analyzed by immuno diffusion technique in agar gel (AGID), and the prevalence of cattle that were positive by AGID test was 55.64% (74/133). The results of this research showed that tuberculos is and leukosis are diseases present in the studied regions and are disseminated in this population, with significant levels, causing risk to the health of animals and people, as the zoonotic bovine tuberculosis.

title: Candongueiros and urban “disorder” in Luanda: an analysis of the social representation of informal transport

description: Abstract Luanda city, the capital of Angola, is characterized by informality and precariousness of activities and services that, to a large extent, follow the logic of social production of urban space. Luanda has “candongueiros” as the main public transport mode. They consist in an informal or semi-informal means of transport responsible for the daily displacement and dynamics of the city, and represent one of the fundamental elements for the expansion of the urban/metropolitan mosaic. However, the peculiarities of this transport mode have led discourses to (dis)qualify it, labeling it as unordered or disorganized. The present study carried out an analysis and discussion of the idea of order usually imposed by a contemporary and global hegemonic logic. The aim is to present the “candongueiros” as a social category from a different urban farming, representative of their social habitus. It is expected to contribute to the socio-spatial understanding of Luanda from the perspective of cultural differences and social representations of informality, which is so common in the reality of contemporary metropolises of peripheral countries. These countries, classified as precarious metropolises by the way they are inserted in the capitalist system of globalized production and consumption, present a paradoxical socio-spatial rationality, object of study of territorial planning.

title: Antifungal activity, in vitro, of the green coffee oil

description: ABSTRACT: The objective of this study was to evaluate the effect of direct contact and volatile fraction of from green coffee oil, tested at concentrations of 500, 1,000, 1,500 and 2,000 µL L-1, on mycelial growth and sporulation of Penicillium roqueforti and Rhizopus stolonifer . The essential oil of clove at a concentration of 800 µL L-1 was used for comparison. At concentrations of 1,500 and 2,000 µL L-1, the green coffee oil in direct contact caused a reduction of sporulation for R. stolonifer, similar to clove oil. In the volatile fraction of the green coffee oil, there was a significant reduction in sporulation of P. roqueforti and R. stolonifer at a concentration of 2,000 µL L-1. The green coffee oil, in direct contact or by volatilization, significantly reduced the mycelial growth and sporulation of both fungi compared to the control.
