Soil Fertility of Decomposed Granite Cut Slopes and Adjacent Vegetated Soils
In Thoreau's time, people were already planting trees to restore landscapes. Throughout this century, public and private organizations as well as countless landowners have worked to restore plant communities to sites that have been disturbed by natural disasters, and by human activities such as mining, road construction, clear cutting, and agriculture. Over the last 20 years, restoration ecolog...
متن کاملChanging trends in characteristics of infantile hydronephrosis
Background : Hydronephrosis (HN) or calycial dilatation is the most common prenatal urologic abnormality. The aim of this study was to identify the possible changes in demographic and clinical manifestations of infantile HN in previously and recently diagnosed patients. Methods : 193 children with infantile HN admitted to Ali-asghar Children's Hospital in two different periods (group 1 1997...
متن کاملStress-Strain Behaviour of Completely Decomposed Granite in Both Triaxial and Plane Strain Conditions
Most of the field problems in geotechnical engineering are in three dimensional state or close to a plane strain condition. Strength and deformation properties of soils in plane strain condition are considerably different from those in an axisymmetric condition. Many researchers have investigated the behaviour of soils under a plane strain condition. However, most of the previous studies have c...
متن کاملTime-Varying Characteristics of Granite Microstructures after Cyclic Dynamic Disturbance Using Nuclear Magnetic Resonance
To investigate the variation in the characteristics of rock microstructure after cyclic dynamic disturbances, a split Hopkinson pressure bar (SHPB) was used to carry out cyclic dynamic impact tests on granite, and the P-wave velocity was used as the characteristic parameter representing the microstructural change. Using the nuclear magnetic resonance (NMR) technique, the porosity and the T2 dis...
متن کاملDynamic Strenth Measurements on Granite and Basalt
Small samples of rock, like those used in laboratory collision experiments, are known to be much stronger than bodies that are meters to hundreds of meters in size [1]. Specifically, the impactor energy per unit target mass needed to shatter the target decreases dramatically with increasing target size. This occurs because the strength of rock, like many other geological materials, depends stro...
