The success or failure of aquaculture heavily depends on how effectively to manage aquatic animal
diseases. In order to analyze the economic effects of aquatic animal disease control, the specific factors
and magnitudes of benefits and costs are identified with and without the proposed project for the disease
control. These...
This study is aimed at evaluating the effectiveness of buyback program implemented last during a 10-year period using a bioeconomic model. Aggregate fisheries stocks are assessed by the surplus-production model and standardized aggregate harvest function is used in the bioeconomic model. The simulation result indicate that the fish stocks are...
The objective of this study was to develop a numerical model for the movement
and fate of chlorinated phenols in groundwater. In the first part, a numerical model for
several different equilibrium and nonequilibrium sorption processes under isothermal
conditions is developed for one-dimensional, steady-state water flow in soil columns.
The...
Delta-sigma analog-to-digital converters traditionally have been used for low speed, high resolution applications such as measurements, sensors, voice and audio systems. Through continued device scaling in CMOS technology and architectural and circuit level design innovations, they have even become popular for wideband, high dynamic range applications such as wired and...
Loading of cryoprotectants into oocytes is an important step of the cryopreservation process, in
which the cells are exposed to potentially damaging osmotic stresses and chemical toxicity.
Thus, we investigated the use of physics-based mathematical optimization to guide design of
cryoprotectant loading methods for mouse and human oocytes. We first...
Atmospheric and surface ocean temperatures in the Antarctic Peninsula region have increased by a few degrees Celsius over the last few decades, and they are the most rapid changes recorded in the Southern Hemisphere during this time period (Cook et al., 2005; Meredith and King, 2005). Associated with this ongoing...
Arrays of hydrophones were deployed within the Bransfield Strait and Scotia Sea (Antarctic Peninsula region) from 2005 to 2009 to record ambient ocean sound at frequencies of up to 125 and 500 Hz. Icequakes, which are broadband, short duration signals derived from fracturing of large free-floating icebergs, are a prominent...
We investigated 32 net primary productivity (NPP) models by assessing skills to reproduce integrated NPP in the Arctic Ocean. The models were provided with two sources each of surface chlorophyll-a concentration (chlorophyll), photosynthetically available radiation (PAR), sea surface temperature (SST), and mixed-layer depth (MLD). The models were most sensitive to...
