Mortality appeared in a relict Scots pine (Pinus sylvestris L.) forest where the sandy association (Pinetum-Festuco vaginatae sylvestris) is unique Carpathian Basin. To identify complex causes of tree mortality, we analysed climatic and soil conditions completed with bryological biotical (pests) surveys. Altogether results show that unfavourable (coarse sand) increasing aridity have led to decl...

• The removal of microplastics by a stormwater treatment train was evaluated. There an abundance in the highway runoff. Rubber and bitumen particles predominated identified microplastics. A gross pollutant trap found to be inefficient at removing Both vegetated sand-only filter efficiently removed Microplastic pose significant threats environment. This study investigated how effective rubber, o...

An algorithm for simulating wind-ripples and moving sand is extended by the detection of fixed objects. This permits us simulation and animation of sand interacting with objects like houses, highways, cactuses, etc. Sand is accumulated on the windward side of an obstacle and the sand relocation and wind-ripples formation is diminished on the leeward side. The wind shadow depends on the object’s...

Horqin Sandy Land is located in northeast China (4241’-4515’N, 11835’-12330’E). The wind-sand topography in Horqin Sandy Land can be described as two series--sand deposition and wind erosion. Wind is the natural force for the formation of wind-sandy environment, under windsandy environment, the wind erosion processes such as sand drifting, dust-storm, etc. occurred frequently because of the fre...

Babies with mitochondrial encephalomyopathies had higher ferritin levels than controls. Although plasma iron levels were simi lar in both groups, babies with mitochondrial encephalomyopathies had lower transferrin levels. Thiobarbituric acid reactive substances in plasma of babies with mitochondrial encephalomyopathies were higher thun in controls suggesting increased lipid oxidation. We s...

The major element composition, including two kinds of clay minerals and moisture content of sound-producing sand are reported for the first time. Sand from 33 beaches in Japan has been found to make sound. Ten sound-producing beaches were selected to compare with silent beach sand. Both sound-producing sand and silent beach sand are mostly composed of quartz and feldspar. The range of SiO2 cont...

Offshore activities often encounter large scale sand patterns, such as sand waves. Sand waves are offshore bed forms occurring at water depths of 10 to 50 m. Their wavelengths can lead up to 500 m and their heights are typically several metres. Furthermore, sand waves have been shown to migrate, with typical velocities of up to metres per year. These dynamic sand waves decrease the least naviga...
