this paper investigates the importance of considering biomass growth and decay for predicting a field scale microbial degradation of btex plume in an unconfined aquifer system in the pump station area of tehran oil refinery (tor), iran. a two-dimensional finite volume model has been presented to predict multi-species reactive transport incorporating physical, chemical and biological processes i...

Empirical Kinetic Models have been used to describe and establish the Anaerobic Digestion kinetics of pig slurry’s (8% TS) Biochemical Chemical Potential. A wide selection were fitted experimental data collected in batch assays different Substrate Inoculum ratios, 0.65 (BMP1) 1 (BMP2). For most suitable model for each BMP assay, statistical tools R2 RMSE, along with Information Criterion AIC BI...

Biogas plants may support the transformation towards renewable-based and integrated energy systems by providing dispatchable co-generation as well opportunities for biogas upgrading or power-to-X conversion. In this paper, a simulation model that comprises main dynamics of internal processes plant is developed. Based on first-order kinetics anaerobic digestion process, production an input feedi...

The objectives of this study were to investigate the effect newly developed blend-pelleted products based on carinata meal (BPPCR) or canola (BPPCN) in combination with peas and lignosulfonate ruminal fermentation characteristics, degradation kinetics, intestinal digestion feed milk values (FMV) when fed high-producing dairy cows. Three dietary treatments Control = control diet (common barley-b...

Additive manufacturing, also known as 3D printing, is beginning to play an unprecedented role in developing many applications for industrial or personalized products. The conductive composite structures require additional treatment achieve electroactive surface useful electrochemical devices. In this paper, the surfaces of carbon black/poly(lactic acid) CB-PLA printouts were activated by electr...

Effects of supplemental glucose and degradable intake protein on nutrient digestion and urea kinetics in steers (Bos taurus) given ad libitum access to prairie hay (4.7% CP) were quantified. Six ruminally and duodenally cannulated steers (initial BW 391 kg) were used in a 4 × 4 Latin square with 2 extra steers. Treatments were arranged as a 2 × 2 factorial and included 0 or 1.2 kg of glucose an...

Following the extraction of oil for biodiesel production, oilseed press cakes are high in fat. As the dietary supplementation of fat is currently considered the most promising strategy of consistently depressing methanogenesis, it follows that oilseed press cakes may have a similar potential for CH4 abatement. As such, this study aimed to characterise the nutritive value of several oilseed pres...

Characterisation and identification of peptides (800 to 5000 Da) generated by intestinal digestion of fish or meat were performed using MS analyses (matrix-assisted laser desorption ionisation time of flight and nano-liquid chromatography electrospray-ionisation ion trap MS/MS). Four pigs fitted with cannulas at the duodenum and jejunum received a meal exclusively made of cooked Pectoralis prof...

The yield of the alpha-fragment of rabbit liver metallothionein 2 was used to test the domain-specificity and mobility of Cd2+ and Zn2+ when bound to metallothionein. Increasing molar ratios of Cd2+ were added to either Zn7-metallothionein or the metal-ion-free apo-metallothionein. The enzyme subtilisin was used to digest those parts of the peptide chain that were not bound to Cd2+. Analysis of...
