Experiments to determine the vertical static bearing capacity are carried out first in laboratory which is taken as a reference for choosing the amplitudes of vertical dynamic loading. Then a series of experiments are carried out to study the influences of factors, such as the scales of bucket, the amplitude and frequency of loading, the density of soils etc.. According to the experimental resu...

INTRODUCTION The growth/differentiation factors (GDFs) are a subgroup of the Bone Morphogenetic Proteins (BMPs) best known for their role in joint formation and chondrogenesis [1,2]. Mice deficient in one of these signaling proteins, GDF-5, exhibit numerous skeletal abnormalities, including shortened limb bones [3]. Because longitudinal bone growth is achieved via the process of endochondral os...

It is well known that characteristics of individual trees, such as tree height, biomass and crown area, can be derived from airborne laser scanning (ALS) and that heights for individual trees can be obtained with an accuracy of 0.5 to 1.5 m. However, the ability to measure the growth of individual trees using ALS has not been documented. This paper reports multi-temporal laser surveys conducted...

objective- to evaluate the application of carbomer 940 hydrogel on saving zone of stasis in skin burn wound. design- experimental study animals- twenty rats. procedures- after shaving the backs, a ‘comb burn’ was contacted bilaterally on the dorsum of the rats 0.5 cm lateral and parallel to the midline by using a brass probe consisting of four rows (10×20 mm) and three interspaces (5×20 mm). al...

The mean vertical velocity in pressure coordinates, and the corresponding height tendency, was computed at intervals of 100 mb from 1000 mb to 60 mb on a mesh covering India and most of southeast Asia. The rate of non-adiabatic heat supply was expressed as a function of the computed height tendency. The results showed pronounced ascent over northeast India and a zone of subsidence over northwes...

Coal mine underground reservoir water storage technology is an effective technical way to achieve high efficiency of coal mining and protection resources. The stability pillar dam plays a decisive role in the safe stable operation reservoirs. Mining adjacent working faces long-term erosion are main influencing factors dam. In this paper, fluid-solid coupling calculation model for deformation ev...

Accurately predicting the height of water flowing fractured zone is great significance to coal mine safety mining. In recent years, most mines in China have entered deep Aiming at problem that it difficult accurately predict under condition large mining depth, mining, inclined length working face and coefficient hard rock lithology ratio are selected as main influencing factors zone. The relati...
