Drilled shaft foundation elements provide a cost-effective foundation alternative for the support of building and bridge superstructure loads. Bi-directional pile loading tests (BDPLTs) to evaluate the capacity of drilled shafts have become popular owing to their capacity to save time and effort as compared to the use of top-down loading...
The relationships between types of wealth components and consumption
expenditures were investigated as a means of better understanding retired
elderly household well-being. Specifically, the concept of mental account was
used to identify the characteristics of different types of wealth components, and
four mental accounts were identified: flow of investment, current...
The total synthesis of a highly potent cytotoxic marine natural product, phorboxazole A, is described. Both a palladium(II)-mediated and a palladium(II)-catalyzed intramolecular alkoxycarbonylation were used as key steps for the preparation of the two cis-2,6-disubstituted tetrahydropyran rings (C22-C26 and C11-C15) of phorboxazole A.
The synthesis used a convergent approach involving...
Computers have made a great contribution to the
design process in various applications, such as design
analysis and simulation. A new technology called
Computer-aided design (CAD) has helped the designer to
design and build very intricate systems.
While most of CAD software is run on workstations or
microcomputers with one...
This research examines bargaining power in the market for Northeast
Multispecies Days-at-Sea (DAS). In 2004, the DAS system was converted
to a tradable input control system. Characteristics of the program include:
1) trading restrictions based on length and power to limit increases in
output, 2) prohibitions that limit the ability...
This study evaluates the prediction of heat and moisture fluxes from a new land surface scheme with eddy correlation data collected at the old aspen site during the Boreal Ecosystem-Atmosphere Study (BOREAS) in 1994. The model used in this study couples a multilayer vegetation model with a soil model. Inclusion...
Hedonic models reveal the marginal implied prices of attributes; these premia represent the intersection of supply and demand for those attributes. Understanding the demand for these attributes is critical for policy analysis that may influence those attributes. While Rosen (1974) proposes a two-step method to recover demand, Kristofersson and Rickertsen...
The North Atlantic U.S. groundfish and scallop processing industries are a tale of two fisheries. The groundfish processing industry has suffered a steep, almost continual decline in landings starting in 1984 that resulted in 2014 landings that were only 16% of 1983 landings. US scallop landings increased from 5 million...
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...
Due to its high strength/weight ratio, 7075 aluminum alloy has
been widely used as an aerospace material. However, it has relatively low fatigue strength and low fracture toughness in the T6
condition. Thermomechanical processing, including pre-cyclic loading and stretching at high and ambient temperatures, has been investigated with the aim...
This research combines a utility-theory consistent model of demand for recreational fishing trips with an age-structured stock dynamics model to provide policy relevant advice to managers of the groundfish fishery in the Northeast United States. We provide an overview of the model and describe the challenges encountered with using this...
This research develops a spatially-explicit model of recreational angler participation in an effort to predict outcomes for the US summer flounder (fluke) fishery under alternative climate scenarios, and inform adaptive management approaches. The mid-Atlantic coastal waters of the US have experienced significant warming in recent years, resulting in noticeable pole-ward...
New Bedford’s share of Atlantic sea scallops landings and revenues increased from 44% in 1996 to 67% in 2013. Explanations for industrial agglomerations often focus on the relative importance of natural advantage and economies of scale or scope. We use the absolute and relative Theil indices of disproportionality to examine...
Concrete is certainly prone to internal deteriorations or defects during the construction and operating periods. Compared with other nondestructive techniques, infrared thermography can easily detect the subsurface delamination in a very short period of time, but accurately identifying its size and depth in concrete is a very challenging task. In...
The potent antitumor agent phorboxazole A was synthesized from six subunits comprising C1-C2 (115), C3-C8 (98), C9-C19 (74), C20-C32 (52), C33-C41 (84) and C42-C46 (85). Tetrahydropyrans B and C containing cis-2,6-disubstitution were fabricated via palladium(II)-mediated intramolecular alkoxycarbonylation which, in the case of tetrahydropyran C, was carried out with catalytic palladium(II)...
Birds, mammals, and fish eat Atlantic Herring. For the first time, fisheries managers in New England are explicitly considering these, and other, predators when setting harvest control rules for the Atlantic Herring fishery. Based on single-species biological reference points, the herring stock is currently well above MSY levels. However, management...
Geographers and regional scientists have long recognized that "near things are more related than distant things." Ports located far from each other may compete through use of the same fishing grounds. We describe trends in competition in the Northeast U.S Sea Scallop Fishery using a Czekanowski Index over the past...
Wireless LANs (WLANs) have been widely adopted and are more convenient as they are inter-connected as wireless campus networks and wireless mesh networks. However, time-sensitive multimedia applications, which
have become more popular, could suffer from long end-to-end latency in WLANs.
This is due mainly to handoff delay, which in turn...
Atlantic sea scallop fisheries in Iceland and the United States have been subject to outbreaks of ‘gray meat’, a disease caused by infestation by a new species of apicomplexan parasite that causes progressive myodegeneration of scallop meats that kills scallops and reduces recruitment. Due to reduced exvessel value, fishermen discard...
The current study investigates gender differences in behavioral regulation in four societies: the United States, Taiwan, South Korea, and China. Directly assessed individual behavioral regulation(Head–Toes–Knees–Shoulders, HTKS), teacher-rated classroom behavioral regulation (Child Behavior Rating Scale, CBRS) and a battery of school readiness assessments (mathematics, vocabulary, and early literacy) were used with...
The rapid disruption of tropical forests probably imperils global biodiversity more than any other contemporary phenomenon¹⁻³. With deforestation advancing quickly, protected areas are increasingly becoming final refuges for threatened species and natural ecosystem processes. However, many protected areas in the tropics are themselves vulnerable to human encroachment and other environmental...
