remote sensing and aerial photographs are used to produce medium to small scale images. however, for detailed information especially to estimate rangeland vegetation canopy cover there is a need to larger scale images. it is therefore necessary to study the technical applicability of different devices such as short range light airplanes, kites, gliders and balloons. in this research, we focused...

Age, height, weight and body mass index (weight/height2) of women finalists from seven running events (100 m, 200 m, 400 m, 800 m, 1500 m, 3000m and marathon) are analysed. The data on 174 runners are derived from four Olympics (Munich, Montreal, Moscow and Los Angeles). On average endurance runners (3000 m and marathon are 4.8 years older, 6 cm shorter and 5 kg lighter for their height than sp...

Canopy height distributions were created from small-footprint airborne laser scanner data for mature coniferous forest in two forest areas in Norway. In total, 82 and 70 georeferenced field sample plots and 39 and 38 forest stands were measured in the two areas, respectively. The average sampling densities were 1.2 m and 0.9 m. Height percentiles, mean and maximum height values, coefficients of...

In order to investigate the effect of rhizobium bacteria, mycorrhiza fungi and foliar application of urea on qualitative and quantitative traits of soybean an experiment was conducted based on randomized complete block design with four replications. The experiment included six treatments as: Control (C), Rhizobium bacteria (R), Rhizobium bacteria + Mycorrhiza fungi (R+M), Rhizobium bacteria + F...

Mapungubwe Cultural Landscape (MCL) woody vegetation was characterized to establish structural and compositional attributes. Stratified random sampling based on major soil types was used and nine plant variables were measured in 137(20x30) m2 sampling plots; these being genera, species and family names; basal circumference; plant height; depth and diameter of tree canopy; number of s...

Despite renewed interest in the nature of limitations on maximum tree height, the mechanisms governing ultimate and species-specific height limits are not yet understood, but they likely involve water transport dynamics. Tall trees experience increased risk of xylem embolism from air-seeding because tension in their water column increases with height because of path-length resistance and gravit...
