Biochar contains quinones and aromatic structures that facilitate extracellular electron transfer between microbial cells and insoluble minerals. In this study, granulated biochar (1.2-2 mm) and powdered biochar (<0.15 mm) were amended to two ferrihydrite (in situ ferrihydrite and ex situ ferrihydrite) enrichments to investigate the effect of biochar with different particle sizes on dissimilato...

Combination of a histochemical fluorescence method for biogem'c monoamines and staining of juxtaglomerular cell granules demonstrated sympathetic nerve terminals in the rat kidney in the walls of the parts of the juxtaglomerular arterioles that contain granulated cells. This forms a morphological basis for a direct influence of sympathetic nervous activity on the liberation of renin. The juxtag...

in this study an empirical model which can be used to predict the rutting parameter (g*/sinδ) for neat and powder rubber modified bitumen describes. the model was developed using 36 unique powder rubber modified bitumen combinations, rubber concentrations were varied at 5% intervals between 5 and 20%. the effects of powder rubber particle size on model accuracy were also studied ultimately a mo...

1. Ground Granulated Blast Furnace Slag Ground Granulated Blast Furnace Slag (GGBFS) is a by product of the steel industry. Blast furnace slag is defined as “the non-metallic product consisting essentially of calcium silicates and other bases that is developed in a molten condition simultaneously with iron in a blast furnace.” [1] In the production of iron, blast furnaces are loaded with iron o...

In this work, hydroxyapatite/silica nanopowders were granulated to fabricate plasma sprayable feedstocks. For this purpose, the wet powders obtained by heating a hydroxyapatite/silica slurry were stirred and sieved. To realize the feedstock application in the plasma spray process, powders were deposited on titanium substrate. The morphology of granulated feedstock and sprayed coating was ...

The article presents research results on obtaining phosphorus granulated fertilizers on the basis of microbiologically activated sewage sludge ashes, ground bones and dried blood from meat industry. Granulation tests were carried out using a laboratory pan granulator as well as on an experimental pilot plant. The aim of the studies was to select the proper composition of the mixture of raw mate...

Utilisation of fly ash and Ground Granulated Blast Slag as an alternative material in concrete reduces the use of OPC in concrete. Evolution of geopolymer concrete cured at ambient temperature broadens its suitability and applicability to concrete based structures. This paper presents the mix proportions and outcome of an experimental study on the density and compressive strength of geopolymer ...

−Five pretreatment methods, namely chemical, acid, heat-shock, freezing and thawing, and base, were evaluated for the enrichment of hydrogen-producing bacteria in anaerobic granulated sludge, which will be subsequently used as seed in biological hydrogen production. All the pretreatments showed positive effects towards improving hydrogen (H 2 ) generation by the microbial population with higher...

se of freeze granulated powders is successfully used as an industrially viable alternative to loose powder sintering for transparent polycrystalline lumina (PCA). Freeze granulation with narrow granule size distribution was realized after suspension condition optimization, with very good owability and regular spherical shapes. The key factors are low viscosity slurries linked to the complex int...

The fibers of the anterior belly digastric muscle of mice, fed a granulated diet for various periods, have been studied histochemically and morphometrically. The diameters of the anterior belly digastric fibers in normal mice fed only a granulated diet were smaller than those in mice fed a solid diet. Differences in the succinate dehydrogenase (SDH) activity of muscle fibers between op/op and n...
