Comparison of in vitro Fermentation with in situ Degradation to Estimate Dry Matter Degradability and Energy Protein Synchronization of Roughage Based Diets

This study was aimed to evaluate the correlation between in vitro fermentation and in situ degradation parameters and to predict dry matter degradability and energy protein synchronization of roughage based diets. Different inclusion of roughage in diets [roughage 50% diet (R50D), roughage 60% diet (R60D), roughage 65% diet (R65D) and roughage ...

Microbial transformations of styrene and [14C] styrene in soil and enrichment cultures.

Two different mechanisms were responsible for the disappearance of styrene in enrichment cultures: (i) a mixed population of microorganisms, capable of utilizing styrene as a sole carbon source, oxidized this substrate to phenylethanol and phenylacetic acid; (ii) the culture also mediated polymerization of the monomer to low-molecular-weight styrene oligomers. This chemical reaction probably oc...

Synthesis, Characterization and Thermal Stability Study of Styrene-based Ionomers I) Programmed Heating Experiments (10 oC/min to 500 oC)

Ionomers are generally described by copolymers having either acrylic or methacylic acid as one component and the other component is mostly either ethylene or styrene. The objective of this research was to study the thermal behaviour and stability of ionomers of styrene with some alkali metal acrylates. These materials have been synthesized by neutralization of the respective copoly...
