[1] The mechanical behavior of hydrate-bearing sediments subjected to large strains has relevance for the stability of the seafloor and submarine slopes, drilling and coring operations, and the analysis of certain small-strain properties of these sediments (for example, seismic velocities). This study reports on the results of comprehensive axial compression triaxial tests conducted at up to 1 ...

Johansson. T. 1995. Site index curves for Norway spruce plantations on farmland with different soil types. Studici Forestulia S~lecicu 198. 19 pp. ISSN 0039-3150, ISBN 91-576-5089-6. Growth data were collected from 157 Norway spruce (Picea abies (L.) Karst.) stands planted on farmland in Sweden. The stands ranged in latitude from 55'N to 66'N. The mean age of the stands was 41 years (range, 25-...

In this paper, a set of physical, geochemical and mineralogical indicators are proposed for the correlation of soil age. The parameters studied allowed the highlighting of trends in soil aging as well as the relating of these trends to specific soil forming processes. Soil aging was marked by a progressive increase in clay content and a decrease in silt/clay ratio, a slight reduction in the CEC...

Playas in endorheic basins are of environmental value and highly scientific because of their natural habitats of a wide variety of species and indicators for climatic changes and tectonic activities within continents. Remote sensing, due to its capability of acquiring repetitive data with synoptic coverage, provides a unique tool to monitor and collect spatial information about playas. Most stu...

Organic carbon (OC) sequestration in degraded semi-arid environments by improved soil management is assumed to contribute substantially to climate change mitigation. However, information about the soil organic carbon (SOC) sequestration potential in steppe soils and their current saturation status remains unknown. In this study, we estimated the OC storage capacity of semi-arid grassland soils ...

Soil plays a key role in the global carbon (C) cycle. Most current assessments of SOC stocks and the guidelines given by Intergovernmental Panel on Climate Change (IPCC) focus on the top 30 cm of soil. Our research shows that, when considering only total quantities, most of the SOC stocks are found in this top layer. However, not all forms of SOC are equally valuable as long-term stable stores ...

The first granulometrical analysis of soil samples from nesting banks of the Malachite Kingfisher Alcedo cristata is reported. In total 56 samples from the Kinshasa area were analysed. Three standardised particle size fractions were determined in all groups of samples (percentage of sand, clay and silt). Mean particle percentage of soil samples from banks occupied by Malachite Kingfishers avera...

The effect of fine particles on turbulence damping and reduction of flow friction coefficient in ribleted pipes, have been investigated experimentally. Tests have been conducted in a ribleted pipe with hydraulic diameter of 18.6 mm, and 20 stream wise riblets of 1.8 mm depth, along the pipe. Flows of water tap with Reynolds number from 5000 to 30000 were compared with flows containing silt-clay...
