Soil instability from tsunami hazards causes substantial damage to coastal infrastructure (e.g., the damage caused by the 2011 Great East Japan Tsunami, or the Heisei Tsunami). Tsunamis are unpredictable, so it is difficult to obtain field-scale measurements. Simulating tsunamis in a laboratory setting is therefore important to further understanding of...
Measurement of physical and chemical solute transport properties of a soil/waste system is necessary to predict pollutant migration in soils. The adsorption component of solute transport is most often determined in the laboratory by performing column studies and batch equilibrium tests. Both of these methods suffer from disadvantages. Batch equilibrium...
Dungeness crab is an important fishery on the Pacific Coast.
The processing subsystem of the fishery is hampered by a variety of
problems that have acted to impede technological innovations that
could improve efficiency and sanitation in seafood plants. This paper
provides background for problems encountered by the processors, discusses...
Knowledge of the pore solution composition and pore solution resistivity can be helpful for determining the durability of concrete structures. Most notably, pore solution resistivity can be used in the calculation of the formation factor of concrete, which is a ratio of the electrical resistivities of concrete and its pore...
Previous studies have shown loss of ethofumesate activity when
the herbicide was applied to dry soil (2% w/w moisture content) in
both field and greenhouse studies, even when rainfall or irrigation
was received within a few days. Laboratory studies were conducted to
determine the mechanism for this activity loss. Dry...
How water moves through soils is of importance to studies of stream hydrology and biogeochemistry. Although translatory flow, which states how soil water is displaced by additional precipitation into streams, is a widely accepted model, Brooks et al. (2010) found evidence that challenged this model. They suggested that there are...
Boulder transport models have been used to develop a historical record of hydrodynamic events. This is done by evaluating the size, location, and composition of boulders that have been removed from their region of formation. Boulder transport is difficult to predict, even under laboratory conditions.
Experiments were conducted to evaluate...
Studying honey bee behavior is a very important aspect of horticulture, especially in recent years as honey bee colonies face population decline, or colony collapse. While studying honey bees, researchers often keep honey bees in captivity, where it can be challenging to meet nutritional and hydration requirements using existing liquid...
Cryopreservation of human red blood cells (RBCs) in the presence of 40% glycerol
allows a shelf-life of 10 years, as opposed to only 6 weeks for refrigerated
RBCs. Nonetheless, cryopreserved blood is rarely used in clinical therapy, in part
because of the requirement for a time-consuming (~1 h) post-thaw wash...
