Brazil annually faces significant challenges with mass movements, particularly in areas with poorly constructed housing, inadequate engineering, and lacking sanitation infrastructure. Campos do Jordão, in São Paulo state, is a city currently grappling with these issues. This paper details a study conducted within a pilot area in Campos do Jordão, where geophysical surveys and geotechnical borehole data were integrated. The geophysical surveys provided 2D profiles, and samples were collected to analyse soil moisture and plasticity. These datasets were combined using a Cokriging-based model to produce an accurate representation of the subsurface conditions. The enhanced modelling of subsurface variability facilitates a deeper understanding of soil behavior, which can be used to improve landslide risk assessments. This approach is innovative, particularly within the international context where similar studies often do not address the complexities associated with urban planning deficits such as those observed in some areas of Brazil. These conditions, including the lack of proper sanitation and irregular housing, significantly influence the geological stability of the region, adding layers of complexity to subsurface assessments. Adapting geotechnical evaluation methods to local challenges offers the potential to increase the efficacy and relevance of geological risk management in regions with similar socio-economic and urban characteristics.

Characterization of soil fauna under the influence of mercury atmospheric deposition in Atlantic Forest, Rio de Janeiro, Brazil

引用

Journal of Environmental Sciences 2015年第6期27卷 217-227页

The increasing levels of mercury（Hg） found in the atmosphere arising from anthropogenic sources, have been the object of great concern in the past two decades in industrialized countries. Brazil is the seventh country with the highest rate of mercury in the *** major input of Hg to ecosystems is through atmospheric deposition（wet and dry）, being transported in the atmosphere over large distances. The forest biomes are of strong importance in the atmosphere/soil cycling of elemental Hg through foliar uptake and subsequent transference to the soil through litter, playing an important role as sink of this element. Soil microarthropods are keys to understanding the soil ecosystem, and for such purpose were characterized by the soil fauna of two Units of Forest Conservation of the state of the Rio de Janeiro, inwhich one of the areas suffer quite interference from petrochemicals and industrial anthropogenic activities and other area almost exempts of these perturbations. The results showed that soil and litter of the Atlantic Forest in Brazil tend to stock high mercury concentrations, which could affect the abundance and richness of soil fauna, endangering its biodiversity and thereby the functioning of ecosystems.

Drying of sugar cane bagasse was theoretically and experimentally studied ina cyclone. The experiments were carried out using hot air as drying agent. The influence of thecyclone conical part was studied. It was shown that the conical part has a great influence on theparticle residence time and, consequently, on moisture reduction. Experimental results were alikeindustrial ones. CFX 4.4 from AEA Technology was used to simulate some experiments. Simulated andexperimental results were close and showed that the presented model leads to a good prediction.

Recovery of valuable metals from waste cables by employing mechanical processing followed by spouted bed elutriation

引用

Particuology 2019年第4期17卷 74-80页

作者： Eduardo H. Tanabe Roger M. silva Daliomar L. Oliveira Junior daniel A. Bertuol Environmental Processes Laboratory (LAPAM) Chemical Engineering Department Federal University of Santa Maria - UFSM Santa Maria RS Brazil

Cables and wires, which are essential parts of equipment for the transmission of both information and electricity, contain valuable materials including copper (Cu) and aluminum (Al). This experimental work evaluates the use of mechanical processing (grinding and sieving), followed by spouted bed elutriation, for separation of the valuable materials (steel-coated copper, copper, and aluminum) present in waste coaxial and internet cables. A recovery efficiency of approximately 90% was achieved for the steel-coated copper in coaxial cables. For in ternet cables, the copper recovery efficiency was approximately 87%. These findings dem on strate that it is possible to separate, recover, and recycle the valuable materials (metals) present in waste cables using simple, low-cost, and efficient mechanical processing followed by spouted bed elutriation.

The effect of sodium reduction and Lactobacillus acidophilus addition(free or microencapsulated)on the quality parameters of requeijao cremoso processed cheese was assessed for 90 days at 5℃.Three formulations were prepared:(CONT)regular salt content and curd fusion(90℃/2 min),(FREE)reduced salt content+free probiotic culture added after curd fusion(90℃/2 min),and(MICRO)reduced salt content+microencapsulated probiotic culture added before curd fusion(70℃/5 min).FREE and MICRO formulations showed increased monounsaturated and polyunsaturated fatty acid content,improved health indices(decreases in thrombogenic index and increases in desirable fatty acid index),and altered rheological properties(higher consistency index,apparent viscosity,elastic properties,and gel strength).In addition,the MICRO formulation showed higher texture sensory acceptance and probiotic counts higher than 6 log CFU/g during storage and simulated gastrointestinal ***,microencapsulation of probiotics with spray chilling represents an innovative solution in requeijao cremoso processed cheese.
