Most of researches of the Si 001) surface have thus far been carried out in specially refined conditions which allowed one to study the most common types of the surface reconstructions such as (2 × 1), c(4 × 4), c(4 × 2), or c 8 × 8) [2 14].
Not only such "strict convexity" conditions generalize the corresponding requirements on the Hamiltonians in Barles and Souganidis (SIAM J Math Anal 31(4):9200039, 2000), but also one of the most refined our conditions covers the situation studied in Namah and Roquejoffre (Commun Partial Differ Equ 24(5–6):883–893, 1999).
The system configured here for shake flask experiments can further be refined since conditions for highly reproducible growth of T. reesei in microtiter plates have been established which allow also the testing for the formation of extracellular enzyme activities (Seidl et al. 2006a).
Ultimately the question of how to refine the conditions, and what conditions to use, is a matter for philosophical judgment.
The big drop in Shell profits was led by the significantly weaker industry refining conditions, that have been widely flagged by the company and others in the industry.
Its recent third-quarter figures were badly hit by a 49% drop in downstream profits as a result of weaker refining conditions caused by industry overcapacity and weak demand.
The results showed that these methods of analysis are promising to monitor the copper passivation in simulated refining conditions.
The optimal refining conditions are nozzle type of holes at bottom and side, refining time of 3 h, refining temperature of 1793 K, refining gas temperature of 373 K, refining gas flow rate of 2 L/min.
The objective of this study was to evaluate physical and mechanical properties of medium density fibreboard (MDF) panels made from kenaf core as function of fibre geometry and refining conditions.
These results refine threshold conditions given by previous metapopulation models.
