Special shaped (high, slim and more or less cylindriform), vulnerable, intact stalagmites (STM) in Domica cave have been examined. Some of these STMs are suitable to estimate the upper limit for horizontal peak ground acceleration generated by paleoearthquake. (This research is the continuation of our previous examination of STMs in Baradla cave, north-east(More)
In contemporary solid-phase synthesis of oligonucleotides, phosphoramidites containing O-beta-cyanoethyl and N,N -diisopropyl groups are the most widespread monomer units. The N,N -diisopropyl phosphoramidite group can be activated by mild acidic treatment and then it easily reacts with nucleophiles (alcohols, water, etc.) to furnish the required(More)
