A1(M) Structure Drainage

Welwyn still requiring improvement to be brought up to motorway standard was the section between Rocstock and Stanborough. The aim here was to find an acceptable solution to a difficult problem, which would overcome the conflicting demands of highway, environment and local needs. The scheme chosen included, on environmental grounds, a 1150 metre long tunnel and in so doing created a ...

Micro Pulse LiDAR: A Critical Tool for Emissions Source Detection

Micro Pulse LiDAR remote sensing data are used to calculate a highly accurate Planetary Boundary Layer (PBL) height to improve plume models that help assess emissions sources. Poor air quality is a growing health issue that has a negative impact on the quality of life for millions of people. To help alleviate this serious problem, scientists at Bubbleology Research International (BRI) have ...

GLOBE 2012 Lessons in Culture Management from Interface and Virgin Unite

Two types of memories stand out from GLOBE 2012, a renowned bi-annual Vancouver event: deeper connections forged with old friends and new connections established with others who we can now call new friends. Those connections may have occurred while relaxing on a couch between sessions, sharing a bite over lunch, relaxing at a bar in the evening, debating after a seminar about the topics ...

Impact of hydraulic loading rate and media type on removal of bulk organic matter and nitrogen from primary effluent in a laboratory-scale soil aquifer treatment system

The effect of hydraulic loading rate (HLR) and media type on the removal of bulk organic matter and nitrogen from primary effluent during soil aquifer treatment was investigated by conducting laboratory-scale soil column studies. Two soil columns packed with silica sand were operated at HLRs of 0.625 and 1.25 m/d, while a third column was packed with dune filtering material and operated at HLR ...

Soil erosion impact on soil organic carbon spatial variability on steep tropical slopes

The main objectives of this study were to evaluate soil organic C (SOC) variability in a representative hillslope of Laos and to quantify the impact of some environmental factors. We collected 2348 soil samples from 581 georeferenced soil pits within a hillslope of northern Laos under traditional shifting cultivation at 0- to 0.05-m depth and then every 0.1 m to 0.35-m depth. The SOC stocks at 0- ...

The cytotoxic and genotoxic effects of metalaxy‐M on earthworms (Eisenia fetida)

As the main optical isomer of metalaxyl, metalaxyl‐M has been widely used worldwide in recent years due to its notable effect on the prevention and control of crop‐diseases. Together with the toxicity and degradation of metalaxyl‐M, the chemical has attracted the attention of researchers. The present study examined the toxic effects of metalaxyl‐M on earthworms at 0, 0.1, 1 and 3 mg kg−1 on ...

Patterns of plant species richness along the drawdown zone of the Three Gorges Reservoir 5 years after submergence

This study was conducted to understand the patterns of plant species richness in the Three Gorges Reservoir after 5 years after 175 m submergence. We hypothesized that hygrophyte and xerophyte species would show different species richness patterns, which was tested by collecting species composition and environmental variable data in 50 m long and 5 m wide transects in the drawdown zone from ...

Molecular characterisation of clinical and environmental isolates of Mycobacterium kansasii isolates from South African gold mines

Mycobacterium kansasii (M. kansasii) is a major cause of non-tuberculous mycobacterial pulmonary disease in the South African gold-mining workforce, but the source of infection and molecular epidemiology are unknown. This study investigated the presence of M. kansasii in gold and coal mine and associated hostel water supplies and compared the genetic diversity of clinical and environmental ...

Floodplain hydraulics in a glaciated bedrock river valley

Data and one dimensional, unsteady theory document the average, seasonal, and diurnal hydraulics of an unconfined aquifer in the surficial floodplain deposit of the Neponset River, which flows through a glaciated bedrock valley in eastern Massachusetts. The 20 m thick silty sand deposit has a permeability of 1.4 × 10−11 m2, a porosity of 0.37, a 600 m halfwidth, and an ...

Blast-Induced Liquefaction of an Alluvial Sand Deposit

A series of six different explosive charges ranging from 0.0045 to 9.06 kg were detonated at a depth of 3 m below a sand island in the South Platte River, northeast Colorado. Pore pressure, particle velocity, and residual pore pressure were measured at several locations. Liquefaction was induced in the dense, saturated, coarse sand at a depth of 3.0 m when peak compressive strain exceeded 0.01%, ...

Characterisation of ambient benzene, toluene, ethylbenzene and m-, p- and o-xylene in an urban traffic area in Bangkok, Thailand

Ambient Volatile Organic Compounds (VOCs) were examined in a heavy traffic urban area in Bangkok, Thailand, on focusing monoaromatic compounds of benzene, toluene, ethylbenzene, m-, p- and o-xylene (BTEX). Passive samplers were used to measure ambient BTEX concentrations in the environment close to very congested roads. Prior to the measurement, the validity of passive sampler performance was ...
