In this study, nineteen unmodified lignins from various sources (hardwood, softwood, wheat straw, and corn stover) and isolation processes (kraft, soda, organosolv, sulfite, and enzymatic hydrolysis) were used to replace 30 wt.% of petroleum-based polyol in rigid polyurethane/polyisocyanurate (PUR/PIR) foam formulations.Lignin samples were characte
The identification of cavitation is very important in technical practice for operational and especially economic reasons.The article deals with the use of another way to measure noise during cavitation.The current approach of measuring noise with an intensity probe is used in practice for identification, but it does not immediately address the posi
Negative consequences upon the Canary Islands population due to catastrophic hazards have been very significant during the period 1995-2005.On one Industrial hand, to appoint an important number of mortal victims, fifty two, and substantial economic losses in material as well as in environmental resources; all of them caused by the action of intens
Planned breeding and conservation strategies for a lesser-known population require an Industrial assessment of complete genetic diversity and population structure analysis in addition to its morphometric characteristics.In the present study, a comparative analysis of the genetic structure of a rare buffalo population, namely Chhattisgarhi, was exte
