Temperature management is one of the primary considerations biogas plant operation, and influences physical biochemical processes. An increase in temperature leads to an hydrolysis rate feedstock, while it can inhibit microorganisms taking part different stages anaerobic digestion. Because complexity processes within digestion process, there a lack knowledge about effects change on efficiency. ...

In view of my discussion of the paper by Wallace and Dowe with an outline of the minimum description length (MDL) principle, of which the minimum message length (MML) principle is seen to be a primitive, restricted and inferior implementation, I do not wish to go into a detailed rebuttal of the numerous issues raised in Professor Wallace’s lengthy discussion. Rather, I will summarize the salien...

Large quantities of seaweed in marine environments and coastal areas can cause serious hygienic environmental problems. Anaerobic digestion (AD) could provide a solution also be useful for the production bioenergy fertilizer. However, AD algae biomass has some limitations further work is required on process. To increase efficiency process, batches 350 mL feedstock containing (Sargassum sp.), in...

BACKGROUND Anaerotruncus colihomonis is a newly described bacterial genus and species isolated from the stool specimens of children. Its clinical significance, however, is unknown. AIMS To describe a case of A colihominis bacteraemia identified by 16S ribosomal RNA (rRNA) gene sequencing and provide an emended description of the species. METHODS An unidentified anaerobic bacillus (strain HK...

Hybrid bio-thermochemical based technologies have the potential to ensure greater feedstock flexibility for production of bioenergy and bioproducts. This study focused on bioconversion syngas produced from low grade technical lignin C2-/C4-carboxylic acids by Butyribacterium methylotrophicum. The effects pH, medium supplementation use crude were analyzed. At pH 6.0, B. methylotrophicum consumed...

The new caving megaprojects that are planned to go into production in the next decade have scheduled horizontal developments at very high rates, which difficult achieve. Research has been conducted seeks model construction times for underground determine feasibility of achieving rates. However, these previous attempts do not consider all operational aspects make up mine development cycle. Here,...

The development of intensive aquaculture is facing the challenge sustainable management effluents. reproductive sectors (i.e., hatcheries) mainly use water recirculation systems (RAS), which discharge a portion wastewater. Anaerobic digestion (AD) could reduce environmental impact this waste stream while producing biogas. study focused on biochemical methane potential (BMP) brackish fish hatche...

Influence of long-term changes in climate and CO2 concentration on intrinsic water-use efficiency (iWUE), defined as the ratio between net photosynthesis (A) and leaf conductance (g), and tree growth remain not fully revealed in humid subtropical China, which is distinct from other arid subtropical areas with dense coverage of broadleaf forests. This study presented the first tree-ring stable c...

Background: To determine whether in the era of cell-free fetal DNA (cffDNA), first and second trimester maternal serum analytes will be obsolete or whether they have a role in predicting adverse pregnancy outcomes. Methods: Retrospective cohort study using maternal serum analyte results from first trimester and sequential screening tests from 1/2002 to 12/2012. Abnormal serum analytes included ...

The traditional view adopted by statistics and econometrics texts is that, in order to solve a nonlinear least squares (NLS) or nonlinear maximum likelihood (NML) problem, a researcher need only use a computer program. This point of view maintains two implicit assumptions: (1) one program is as good as another; and (2) the output from a computer is reliable. Both of these maintained assumptions...
