Within the literature, capillary barriers have been suggested as an alternative hydraulic barrier in cover liners for waste dumps. When a waste dump reaches its full capacity, cover liners are usually constructed over the waste mound to seal the waste from the surrounding environment. One main function of a cover liner is to prevent substantial amounts of water infiltrating into the waste mater...

There has been leakage of radioactive materials from the Fukushima Daiichi Nuclear Power Plant. A heavily contaminated area (≥ ¹³⁴,¹³⁷Cs 1000 kBq m⁻²) has been identified in the area northwest of the plant. The majority of the land in the contaminated area is forest. Here we report the amounts of biomass, litter (small organic matter on the surface of the soil), coarse woody litter, and soil in...

In the BC central interior, fine-textured glaciolacustrine sediments are an important soil parent material on many productive forest sites, particularly along major river valleys such as the Fraser and Nechako. With easy proximity to major transportation routes and wood processing facilities, many such sites were harvested early in the history of logging in this region, long before the advent o...

The aim of this study was to identify leaf physiological traits, which could be used in selecting high yielding genotypes among 12 sugar beet cultivars grown in two contrasting pedo-climatic environments. In the stressful Site 1 (high temperatures, low rainfall, heavy-textured soil), high yielders had cooler leaves (lower ΔT) and thus, transpired (E) and photosynthesized (A) more. Also, these c...

This paper presents a coarse-to-fine approach to eliminate unexpected shadows of multiple pedestrians from a static and textured background using Gaussian shadow modeling. At the coarse stage, a moment-based method is proposed to estimate the rough boundaries between shadows and moving objects. Then, at the fine stage, the rough approximation of shadow region provides a key to model shadows. Th...
