COMPARISON OF CALIBRATION CHARACTERISTICS OF DIFFERENT ACOUSTIC IMPACT SYSTEMS FOR MEASURING BEDLOAD TRANSPORT IN MOUNTAIN STREAMS

Comparison of calibration characteristics of different acoustic impact systems for measuring bedload transport in mountain streams

The Swiss plate geophone (SPG) system has been installed and tested in more than 20 steep gravel-bed streams and rivers, and related studies generally resulted in rather robust calibration relations between signal impulse counts and transported bedload mass.Here, we compare this system with three alternative surrogate measuring systems.A variant of

Genetic association between regulation of GTPase activity pathway and high-altitude essential hypertension among Chinese Tajiks

Objective To screen the single nucleotide polymorphism (SNP) loci and related genes that are significantly associated with essential hypertension among Chinese Tajiks by using exon sequencing and to reveal the unique essential hypertension related gene polymorphisms of the high-altitude minority.Methods A total of 62 Chinese Tajiks (26 in the contr
