HOW EFFICIENT ARE AGITATORS IN BIOGAS DIGESTERS? DETERMINATION OF THE EFFICIENCY OF SUBMERSIBLE MOTOR MIXERS AND INCLINE AGITATORS BY MEASURING NUTRIENT DISTRIBUTION IN FULL-SCALE AGRICULTURAL BIOGAS DIGESTERS

The goal of this work was to evaluate the efficiency of two different agitation systems by measuring the nutrient distribution in a digester fed with renewable energy crops and animal manure.The study was carried out at the practical research biogas plant of Hohenheim University.A unique probe sampling system has been developed that allows probe sa

This study explored the organisation of the semantic field 1f2 paint and the conceptual structure of moving experiences by investigating German-language expressions referring to the emotional state of being moved.We used present and past participles of eight psychological verbs as primes in a free word-association task, as these grammatical forms p

This study developed vetality twist and lick a simple method to distinguish the animal source of chondroitin sulfate (CS) through systematic investigations and comparisons of the terahertz (THz) spectral characteristics of CS with different animal sources.CS from shark had the lowest THz absorption coefficient, followed by that from cattle, with CS

Abstract Background Kaffa, Sheka and Bench Maji zones of Southern Ethiopia are high honey production areas with dense forest coverage.However, due to the traditional production system, the productivity per hive is low.To exploit this production potential in these zones by increasing productivity per hive, different governmental and non-governmental

The pile-beam composite structure hus726040als214 in high-elevation debris flow areas is selected as the research object.Based on characterizing the pile-beam composite structure, the particle-flow simulation analysis program and the explicit dynamic analysis program were used to study comparatively the blocking effects of single-row piles and two-
