Abstract. Soil moisture heterogeneity has an effect on the rainfall–runoff characteristics of a landscape. The aggregate effect on the mean water balance over an area can be quantified successfully using models such as the PDM (Moore, 1986) and TOPMODEL (Beven and Kirkby, 1979). These rainfall–runoff models have been embedded in the large-scale land surface schemes used in meteorological models. However, there is also a requirement (e.g. model validation) to identify the spatial structure of the fine-scale soil moisture heterogeneity that makes up these aggregate models. In some types of lands

Abstract:
Titanium (Ti) is widely used as a biomaterial for endosseous implants due to its relatively inert surface oxide layer that enables implanted devices the ability of assembling tissue reparative components that culminate in osseointegration. Topographic modifications in the form of micro- and nanoscaled structures significantly promote osseointegration and enhance the osteogenic differentiation of adult mesenchymal stromal cells (MSCs). While the biological mechanisms central to the differential responses of tissues and cells to Ti surface modifications remain unknown, adhesion and morphological

Abstract Over 9000 records of teleseismic P-wave coda from the Southern California Seismic Network are used to map lateral variations in P to Rg scattering strength and the group velocity of scattered Rg. Building on the results of Revenaugh (1995a), we use the correlation of scattering strength and topographic roughness as an indicator of model fit to estimate group-velocity dispersion over five frequency bands between 0 and 3 Hz. Rg group velocity displays normal dispersion, decreasing from 2.7 ± 0.3 km/sec for frequencies between 0 and 0.6 Hz to a low of 2.2 ± 0.4 km/sec for the 2.0 to 3.0

Abstract:
Insect pests pose a significant threat to alpine ecosystems, especially under rapid environmental change conditions. Therefore, it is necessary to explore the effects of environmental factors on insect pest risks and provide methods for pest management in alpine regions. Habitat heterogeneity and topographic variation are the indicators of insect pest risks. However, few studies have explored the effects of habitat heterogeneity and topographic variation on insect pest risks in alpine regions.

However, bee richness patterns and their relationship with environmental heterogeneity in the Atlantic Forest remain underexplored.

Abstract:
Alpine plant communities can be exceptionally diverse at a fine scale, and they often exhibit fine scale topographic variability. High species diversity is often attributed to spatial and temporal heterogeneity in the environment. The goal of this study was to test for a positive relationship between microtopographic heterogeneity and species diversity of alpine plants. Species diversity of vascular plants was sampled at 8 sites in Glacier National Park, MT during the summer of 2009. Species richness was assessed both within a 1 x 1 m plot and at 100 points spaced 10 cm apart within the plot.

Abstract:
Abstract The Barremian-Aptian, Kharaib Formation is among the main reservoir units in the Middle-East. The Kharaib Formation is broadly divisible into three main zones: the Upper, Middle and Lower Kharaib, which are defined based on their distinct sedimentological characteristics. The Kharaib interval has been extensively studied across the region; however, the inherent heterogeneity associated with sediments always makes it challenging for interpretation of the depositional facies, stratal geometries, and the prediction of their reservoir properties. This study focuses on the Middle and Upper

Abstract:
Abstract The Yan'an tight gas field, situated in the Ordos basin in central China, is emblematic of a typical tight gas reservoir. The field's development planning has been confronted with numerous challenges arising from conditions characterized by high geological heterogeneity, low porosity, multiple production formations, low lateral sand continuity, and a complex topography. Among the pivotal tasks in field development that necessitate addressing these challenges are the screening of well types and the optimization of pad locations. The judicious selection of well types, including horizont

The influence of endothelium on vasomotionin resistance vessels was studied in an isolated, buffer-perfused rabbit ear preparation using novel microangiographic techniques and haemoglobin as a specific inhibitor of EDRF. In constricted preparations acetylcholine and Substance P, whose action is EDRF-dependent in large vessels, induceddilatation in vessels down to 25um in diameter which was inhibited by haemoglobin. Log (IC50>q) values calculated from diameter changes were the same in the central artery, GO, and its first three generations of branch vessels Gl, G2 and G3 (ie down to 7Oum) be
