Concrete cores extracted from the same structural element may show variations in strength resulting a lack of homogeneity and grade compactness. This paper, while accounting for such variability, introduces new formulation to assess both situ potential characteristic concrete. The first part addresses Society report 11 on formulations introduced by author that considers coefficients take into a...

Inaccurate estimation of nuts volume in a hopper may likely influence the design some components palm nut processing system such as shaft, rotor, electric motor power, supporting rods, etc. In an effort to address this challenge voids/ spaces were considered inherent when stored vessel. study, 5 kg dried and ready crack mixed varieties grouped based on their minor diameter (d_1) small size: d_1...

The objective of this work was to evaluate the hydrogen storage capacities of various activated carbon materials in form of granules, powders, fibers and clothes under cryogenic and ambient temperature conditions (77K 293K), at pressures up to 30Bar. The experimental data were analyzed for carbon samples covering a wide range of BET surfaces and microporous volumes. At 293K, the storage capacit...

Recent research suggests that the resurgence of bed bugs in the U.S. has occurred at an alarming rate. Assumptions have been made that socioeconomic status is not associated with the prevalence of bed bug infestations. Little information is available at the local level, however, about the prevalence of bed bugs in private homes. The authors' pilot study aimed to identify prevalence, knowledge, ...

In this study, we present the DEM-SPM method, a Lagrangian-Lagrangian coupled algorithm, for simulating solid-liquid flows involving free surfaces. The DEM solid phase and the SPH liquid phase are connected using the local averaging technique, where the governing equations are modeled taking account of the local mean voidage. Conservative forms of momentum balance are derived via a variational ...

A capacitance measurement system is developed for the measurement of gas-liquid two-phase flow in glass micro-pipes with inner diameters of 3.96, 2.65 and 1.56 mm, respectively. As a typical flow regime in a micro-pipe two-phase flow system, slug flow is chosen for this investigation. A capacitance sensor is designed and a high-resolution and high-speed capacitance measurement circuit is used t...

OBJECTIVE To share four Canadian cities' experiences with bed bug infestations and to explore public health roles in managing them. METHODS We summarize presentations from a workshop at the 2010 Canadian Public Health Association Conference which examined the re-emergence of bed bugs in Canada and compared management approaches of municipal and public health authorities in four large Canadian...
