Macropore transport of chemicals in soil often causes unexpected contamination of groundwater. The effect of soil structure on the functions of various sized macropores was assessed, investigating transport of nonreactive bromide (Br) under matric heads of 0, 2, 5 and 10 cm using undisturbed soil columns from A, Bw and E horizons of a Thatuna silt loam soil (fine-silty, mixed, mesic Xeric Argia...

Increasing demand in automotive, construction, and medical industries for materials with reduced weight high mechanical durability has given rise to porous composites. Materials combining nano- microporosity a well-defined cellular macroporous architecture offer great potential reduction while maintaining durability. To achieve predictable performance, it is essential apply experimental computa...

Both Gram negative and positive bacterial strains are known as the most frequently responsible causative agents for wound infections. These infections can resulted in morbidity mortality due to severity. Antimicrobial have often been preferred treat these In this respect, Cefuroxime (CXM) belongs second-generation cephalosporins could be suggested against recent years, designing of drug deliver...

Soil compaction can decrease potential crop yield and is frequently found in no-till cultivation systems, but there islittle information on the critical limits of soil physical properties these conditions, especially subtropical soils. The objectives ofthis study were to evaluate infl uence tractor traffi c identifi es bulk density,soil degree, macro, microporosity corn black oat assessed situ ...

Porous hydroxyapatite (HA) and glass reinforced hydroxyapatite (GRHA) with adequate macro and microporous structure were developed, aiming at being used as drug delivery carrier of antibiotics, for the in situ treatment of periodontitis. Materials were characterised by XRD and FTIR, presenting no changes from similar dense materials. Mercury intrusion porosimetry revealed micropores of less tha...

Abstract Reliable quantitative analysis of digital rock images requires precise segmentation and identification the macroporosity, sub-resolution porosity, solid\mineral phases. This is highly emphasized in heterogeneous rocks with complex pore size distributions such as carbonates. Multi-label carbonates using classic methods multi-thresholding sensitive to user bias often fails identifying lo...

In no-tillage areas, cover crops are a continuous supply of organic matter and other positive improvements to the soil’s structural quality. We evaluated soil physical attributes in area cultivated with brassica on residues under no-tillage. Six coverages [1-Brachiaria (B), 2-Sunn hemp (S), 3-Pearl millet (M), 4-S + B; 5-B M; 6-S M] native (Cerrado biome), were for resistance penetration (RP), ...

Organic amendments are believed to help increase the soil carbon storage and therefore improve quality, which may be important in context of climate change. However, added value organic for farmers must clearly demonstrated order convince them utility their use. The aims this study were: (i) investigate impact on maize compost vermicompost combined with two levels (negligible significant) plant...

Citrus companies have sought and developed alternative systems of tillage or implanting orchards so as not to significantly alter the physical chemical attributes soil and, consequently, root development plants. Therefore, aim this study was identify that most influence volume orange crop in different systems. The experiment carried out region Avaré, state São Paulo, Brazil, Utissol Oxisol. For...

Green roofs are very popular and their individual surface area is constantly growing. Considering that the organo-mineral materials used in planting growing media (GM) often non-renewable resources, search for alternative from waste recycling a challenge. Among these, recycled polyurethane (PU) foams light porous. The objective of this study was to evaluate potential agronomic valorisation PU e...
