this study was conducted to determine the chemical composition, digestibility, degradability and nutritive value of madder, rubia tinctorum l.  and alfalfa medicago sativa. using in vitro and in situ measurements. the mean values for om, cp, ndf, adf and ee were 892.5, 172.0, 306.5, 219.4 and 16.0 g/kg dm for madder hay, and 921.3, 141.4, 482.0, 361.1 and 6.50 g/kg dm for alfalfa hay, respectiv...

In this work, we examined the microstructures formed during the pyrolysis of naphthalene mixed with AlCl3 catalyst, in the crit-ical temperature range of 300–500 C and at varying pressures. In addition, non-rigidized preforms were densified by multiple cycle in situ transformation and compared the process with impregnation using fully transformed AR mesophase pitch under similar conditions....

We have developed a new experimental platform for in situ scanning transmission electron microscope (STEM) energy dispersive X-ray spectroscopy (EDS) which allows real time, nanoscale, elemental and structural changes to be studied at elevated temperature (up to 1000 °C) and pressure (up to 1 atm). Here we demonstrate the first application of this approach to understand complex structural chang...

A comparative study of holocentric chromosomes in the triatomine species Panstrongylus megistus, Rhodnius pallescens and Triatoma infestans was carried out in order to characterize heterochromatin, rDNA active sites and nucleolar proteins. Cytological preparations of seminiferous tubules were stained by silver impregnation, C banding, fluorochromes cma3/da and dapi/da, and fluorescent in situ h...

In order to improve the fire retardancy of wood eco-friendly method forin situformation CaCO3deep inside wood's structure was proposed by vacuum-pressure impregnation only one component – water solution calcium acetoacetate.

The present research investigates the ability of graphene oxide nanosheets for treatment of dairy wastewater, using In Situ Sludge Magnetic Impregnation” (ISSMI) to separate sludge after adsorption process. To increase the interaction between magnetic nanoparticles and graphene oxide, the former has been functionalized, using 3-Aminopropyl triethoxysilane, with the synthesized graphene oxide an...
