Cover board arrays were used to measure the relative abundance of macroinvertebrates and terrestrial salamanders on prescribed burn and control sites in xeric southern Appalachians of northern Georgia and southeastern Tennessee pine-oak forests. Three microsite variables were measured at each cover board: cover board moisture level, temperature under the cover board, and soil moisture. Soil moi...

OBJECTIVES Unicompartmental knee arthroplasty (UKA) is a demanding procedure, with tibial component subsidence or pain from high tibial strain being potential causes of revision. The optimal position in terms of load transfer has not been documented for lateral UKA. Our aim was to determine the effect of tibial component position on proximal tibial strain. METHODS A total of 16 composite tibi...

Loss of soil nutrients in runoff accelerates eutrophication of surface waters. This study evaluated P and N in surface runoff in relation to rainfall intensity and hydrology for two soils along a single hillslope. Experiments were initiated on 1- by 2-m plots at foot-slope (6%) and mid-slope (30%) positions within an alfalfa (Medicago sativa L.)-orchardgrass (Dactylis glomerata L.) field. Rain ...

Abstract Hillslope hydrology in agricultural landscapes is complex due to a variety of hydropedological processes and field management possibilities. The aim was test if there are any differences soil properties water regime along the hillslope compare vineyard rows (vine) with inter-rows (grass) area for those properties. study determined that significant contents particle fractions, pH, humus...

Let a smooth family of Riemannian metrics g(τ) satisfy the backwards Ricci flow equation on a compact oriented n-dimensional manifold M . Suppose two families of normalized n-forms ω(τ) ≥ 0 and ω̃(τ) ≥ 0 satisfy the forwards (in τ) heat equation on M generated by the connection Laplacian ∆g(τ). If these n-forms represent two evolving distributions of particles over M , the minimum root-mean-squa...

Ultrasound parameters were proposed to characterize femur in vitro from rats. Six quantitative parameters (Apparent Integrated Ultrasonic Backscatter AIB, Frequency Slope of Apparent Backscatter – FSAB, Temporal Slope Apparent Backscatter TSAB, Integrated Reflection Coefficient IRC, Slope and Frequency Integrated Reflection FSIR and Temporal Slope Reflection Coefficient TSRC) were applied to th...

We determined the amount of information needed to estimate watershed-scale transpiration in a Japanese cedar (Cryptomeria japonica D. Don) forest from sap flow measurements of individual trees. Measurements of tree biometrics (diameter at breast height (DBH) and tree sapwood area (AS_tree)), and tree-to-tree and radial variations in xylem sap flux density (Fd) were made in two stand plots, an u...

Use of electromagnetic induction (EMI) sensors along with geospatial modeling provide a better opportunity for understanding spatial distribution of soil properties and crop yields on a landscape level and to map site-specific management zones. The first objective of this research was to evaluate the relationship of crop yields, soil properties and apparent electrical conductivity (ECa) at diff...
