bioavailability of three rumen protected methionine (met) sources with different protection methods (mepron® m85, evonik industries, germany; methioplus®, soda nutrition, italy and methilock®, tehrandaneh co. iran) were evaluated in 2 experiments with 6 canulated non-lactating holstein cows. in experiment 1, the ruminal in situ and mobile bag techniques were used for assessing ruminal degradabi...

A number of techniques have been developed to characterize the attosecond emission from high-order-harmonic sources. These techniques are broadly classified as ex situ, where the attosecond pulse train photoionizes a target gas in the presence of an infrared field, and in situ, where the measurement takes place in the medium in which the attosecond pulses are generated. It is accepted that ex s...

background: parental anxiety while waiting for the results of amniocentesis has been investigated by many authors. it seems that the implementation of faster techniques such as fluorescence in-situ hybridization (fish) will have some benefits in reducing this anxiety. besides the patients' attitudes to choosing this method, gynecologists who are the persons responsible for treatment, must feel ...

the present experiment was carried out to investigate the nutritive value of banana tree leaves and stems silage by use of in vitro gas production and as well in situ nylon bag techniques. experimental treatments were comprised of: 1- stems and leaves of banana trees (control), 2- stems and leaves of banana trees’ silage without addition of any additive, 3- stems and leaves of banana trees’ sil...
