To enhance the codigestion of degradation and improve biomethane production potential, sugarcane bagasse and filter mud were pretreated by sodium hydroxide NaOH 1 N at 100°C for 15, 30, and 45 minutes, respectively. Biomethane generation from 1-liter batch reactor was studied at mesophilic temperature (37 ± 1)°C, solid concentrations of 6%, and five levels of mixing proportion with and without ...

By using the data of logging, cuttings thin section identification and analysis in study area to four characteristics Nantun Formation reservoir their relationship, lower limit standard effective physical property is established by logging interpretation model mud content, porosity, permeability saturation, mercury injection method, oil production test method cumulative frequency statistics met...

Good agreement with field data has been obtained when using a commercial kick simulator to analyse a 56 bbl gas kick taken in a 59 deg deviated wellbore. Fast kick detection and reaction are necessary when drilling at high rates of penetration since high pump rates, necessary for hole cleaning and cuttings transport, imply that a gas influx may be rapidly circulated to surface. A simulated exam...

the “human mud” is one of the motifs of the poetry attributed to khayyam. the imagery, concepts and philosophical thoughts about the human being's origin (creation, death, life after death) form the essence of this poetry. are the khayyam's quatrains about creation original and new? or do they have a precedent in the ancient world poetry? why does the iranian literary criticism claim that this ...

Coastal reclamation has been carried out along the coastal areas near Shenzhen, China in a large scale since 1980s by dumping fill materials over the marine mud at the sea bottom. Usually the area to be reclaimed is drained first and some of the mud is airdried for a few weeks before it is buried by fill. After reclamation, the terrestrial groundwater, which is relatively acidic and with high d...

Performances of two common types of red mud, Bayer red mud and Sintering red mud, were investigated in this research. Their compositions, mechanical properties and microstructure characterization were measured through XRD, TG and SEM analysis. Their shear strength, particle size, density and hydraulic characteristics also had been performed. Huge differences between the basic mineral types of t...

MUDENG (Mu-2-related death-inducing gene, MuD) is revealed to be involved in cell death signaling. Astrocytes, the major glial cell type in the central nervous system, are a source of brain tumors. In this study, we examined MuD expression and function in human astroglioma cells. Stimulation of U251-MG cells with tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) resulted in a 40% ...

decision-making by entrepreneurs is a process that cannot be explained by existing models. literature analysis reveals a gap due to the teleological approach of existing models. this research aims to conceptualize central elements of new venture creation decision-making process in a selected sample of nascent entrepreneurs in iranian high-tech industries based on a non-teleological approach and...

Nonlethal predator effects can significantly influence trophic interactions, and in this study we examined how size relationships between predators and prey would influence the ex pression of nonlethal predator effects. We assessed how size and vulnerability to predators would influence nonlethal effects in bivalve species common to oyster reefs. We used 2 size classes of mussels Ischadium recu...
