Manure Incorporation and Reduced Tillage Corn Trial [PDF]

open access: yes, 2016
Timely manure incorporation can reduce nutrient losses to the atmosphere and surface runoff. Keeping valuable nutrients, like nitrogen, in the soil can help reduce the purchase of expensive commercial fertilizers.

Waste activated sludge high‐rate treatment of septage: Biodegradability studies and contact phase trials towards a cleaner environment

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract The waste activated sludge high‐rate (WASHR) process, developed in our previous study, is used for septic wastewater treatment. This high‐rate contact stabilization pre‐treatment uses typical waste streams found in wastewater treatment plants to reduce a portion of the loadings on the main treatment trains.

The Influence of the Preparation Primix Bionorm K on the Digestibility of the Nutrients in the Fodders for Young Pigs

open access: yesScientific Papers Animal Science and Biotechnologies, 2023
The study was carried out in order to determine nutrient digestibility in breed gilts under the influence of the supplementation of the mixed fodder with the preparation pro-prebiotic Primix Bionorm K at the level of 0.15, 0.30, and 0.45 kg/t.

Protein turnover downstream of the Nipbl/CRL4 axis contributes to abnormal development in zebrafish embryos

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background Mutations in cohesins cause cohesinopathies such as Cornelia de Lange Syndrome (CdLS) and Roberts Syndrome (RBS). Prior findings demonstrate that Esco2 (a cohesin activator) and Smc3 (a core cohesin subunit) regulate the CRL4 E3 ubiquitin ligase. SMC3 mutations, however, account for a small percentage of CdLS.

Anaerobic digestion of cellulosic wastes: pilot plant studies

open access: yes, 1985
Anaerobic digestion is a potentially attractive technology for volume reduction of low-level radioactive cellulosic wastes. A substantial fraction of the waste is converted to off-gas, and a relatively small volume of biologically stabilized sludge is produced.

Nutrient digestibility and growth response of rainbow trout (Salmo gairdneri ) fed different carbohydrate types [PDF]

open access: yes, 1986
Seven groups of fingerling rainbow trout (S. gairdneri ) were fed for 10 weeks on 0%, 10%, 20% and 30% of cassava or rice in isonitrogenous diets. Optimum growth and food utilization was at 20% dietary cassava.
