The Hanford Site was one of the DOE’s major nuclear weapons production sites from 1940 to 1989. Over time, 67 of the 149 single-shell tanks have leaked or are suspected of having leaked [1]. Contaminants such as Tc and U have been found in elevated concentrations in the vadose zone and groundwater beneath the single shell tank farms [2]. In order to make decisions on remedial actions, numerous ...
Scalding with unheated water in the first tank of a simulated three-tank scalder was tested to determine whether carcass bacteria, efficiency of feather removal, and cooked breast meat tenderness are affected as compared with carcasses scalded at the same temperature (57 C) in all tanks. This experiment was performed on 3 d using 6-wk-old broilers. On each day, eight birds per treatment were pr...
As implementation of the Ballast Water Convention draws nearer a major challenge is the development of protocols which accurately assess compliance with the D-2 Standard. Many factors affect the accuracy of assessment: e.g. large volume of ballast water, the shape, size and number of ballast tanks and the heterogeneous distribution of organisms within tanks. These factors hinder efforts to obta...
The paper describes the Fuzzy–PID cascade controller to control the level of horizontal tank that has diameter 300 mm and 480 mm long. Interface card module PCI-6024E in computer and Lab View software program is used for built the cascade controller. Structure of its where the inner loop is a PID controller for regulating flow rate of system and outer loop is a Fuzzy logic controller for contro...

Fish are increasingly popular subjects in behavioural and neurobiological research. It is therefore important that they are housed and handled appropriately to ensure good welfare and reliable scientific findings, and that species-appropriate behavioural tests (e.g. of cognitive/affective states) are developed. Routine handling of captive animals may cause physiological stress responses that le...
Tank bottoms from a Williston Basin oilfield were applied to test plots in which crops were subsequently planted. Naturally occurring microbes reduced the 6% total petroleum hydrocarbon (TPH) concentration to 3.8% in a few months (a 37% reduction), but reduced it no further, possibly due to an insufficient amount of nitrogen or water or both. For the first three years of the study, the 6% TPH t...
The key to properly diagnosing cleaning and sanitation problems is identifying the types of bacteria present in bulk tank milk. Periodic culturing of bulk tank milk is also an essential tool to diagnose milk quality issues related to mastitis. These methods are described in greater detail in Reinemann et al. (2002) and Ruegg and Reinemann (2002). Collection of the type of bulk tank culture data...
This paper describes a tank-scale test setup and experimental methodology used to investigate coupled heat transfer water flow processes during heating of compacted MX80 bentonite high temperatures. Specifically, temperature 200°C was maintained by cylindrical element at the center layer containing an array temperature, dielectric, relative humidity sensors. In addition providing evaluation spa...
