  • The Thermal Probe—Measurement of the Thermal Conductivity and Drying Rate of Soil in the Field

    The thermal probe is a metal rod with an internal heating element and temperature sensor. In the field it is pushed into a predrilled hole in otherwise undisturbed soil, and the thermal properties of the soil are estimated from the temperatures recorded at intervals after a constant power is supplied to the heating element. The following are discussed in this paper: the theory behind the methods ...

  • Hydraulic conductivity of residual lateritic soil permeated with organic chemicals

    In this study, three lateritic soil samples compacted at 2% wet of optimum moisture content with British Standard Light (BSL) effort were permeated with acetone and ethanol over a range of concentrations (0, 25, 50, 75, 100%), while benzene and heptane were used at full strength. Hydraulic conductivity of specimens permeated with diluted solutions of acetone and ethanol ( ...

  • Joint estimation of hydraulic conductivities of two sand samples in a W-tube system with a bi-exponential response

    The motivation for this paper is the practical problem of interpreting bi-exponential rate-of-rise curves that are observed during many field piezometric tests. In the authors' previous study, a laboratory W-tube system of water flow through two samples of sand was introduced with an adequate mathematical model. The desired bi-exponential character of water flow was obtained by placing two ...

  • Mine remediation case study

    Bartow, Florida GeoView, Inc. performed a geophysical investigation across a 200 acre site in Polk County, Florida. It had been reported that clay slimes from former mining operations had been deposited on the site. The purpose of the investigation was to help determine the horizontal and vertical extent of the clay slimes. Due to the large size of the site and limited budget, the ...

  • Performance evaluation of exhaust air recirculation system of mixed mode solar dryer for drying of onion flakes

    This paper deals with the performance of mixed mode type solar dryer for drying onion flakes. During the experiments, no load and full load test were conducted to find out the effectiveness to the system with or without recirculation of exhaust air. The drying and thermal efficiencies and heat utilisation factors were recorded as 21%, 74% and 31% respectively, more compared to recirculation of ...

  • Behavior of Flame Spread Downward over Thick Wood Sheets and Heat Transfer Analysis

    To investigate the flame spreading mechanism over charring materials under natural convection, wood sheets from 0.9 to 3 mm thickness have been chosen. The variation of mean flame spread velocity V with thickness  is measured. Typical flame shapes over the wood surfaces are recorded using CCD. The temperature fields in the gas phase are examined by a set of fine thermocouples. On the basis ...

  • Determination of diurnal water level fluctuations in headwaters

    The aim of this paper is to study diurnal fluctuations of the water level in streams draining headwaters and to identify the controlling factors. The fieldwork was carried out in the Gryżynka River catchment, western Poland. The water levels of three streams draining into the headwaters via a group of springs were monitored in the years 2011–2014. Changes in the water pressure and water ...

  • Bayesian approach to potency estimation for aquatic toxicology experiments when a toxicant affects both fecundity and survival

    Chemicals in aquatic systems may impact a variety of endpoints including mortality, growth, or reproduction. Clearly, growth or reproduction will only be observed in organisms that survive. Because it is common to observe mortality in studies focusing on the reproduction of organisms, especially in higher concentration conditions, the resulting observed numbers of young become a mixture of zeroes ...
