The status of fisheries resources on coastal and offshore areas is getting worse in Taiwan. Thus, to establish a fishery resources management system has become the main task among stakeholders. In this study, we would like to examine the feasibility of imposing the community-based co-management system and setting closed fishing...
With the expansion of transport, increasing car ownership, rapid increase in outbound travel and new interests in nature based eco-tourism, and the adoption of 5 work days, marine eco-tourism is expected to have a very promising future and need more detailed preparation and planning. While marine eco-tourism occupies 30% of...

Verification of fast reactor safety requires experiments
wherein fuel bundles, enclosed in massive steel capsules, are subjected
to simulated accident conditions in reactors such as TREAT(16)
at ANL Idaho. To date, only small bundles (one to seven pins) have
been tested in the experimental series. Determination of the fuel
configuration...
The importance of soil factors to the establishment of tree crops is well recognized by forest soil scientists and foresters. It has, however, been overlooked by far too many foresters responsible for major forestation projects.
The soil factors found to be significant in the establishment of both planted stock and...
The dynamic watershed acid-base chemistry model of acidification of groundwater in catchments (MAGIC) was used to calculate target loads (TLs) of atmospheric sulfur and nitrogen deposition expected to be protective of aquatic health in lakes in the Adirondack ecoregion of New York. The TLs were calculated for two future dates...
The purpose of this report is to describe a large tumor complex that was found protruding into the pericardial cavity of a single Ostrea lurida from Yaquina Bay, Oregon.
We form a new ‘blended’ data set of sea level anomaly (SLA) fields by combining gridded daily fields derived from altimeter data with coastal tide gauge data. Within approximately 55–70 km of the coast, the altimeter data are discarded and replaced by a linear interpolation between the tide gauge and remaining...

The development of nanomaterials and the potential enhancement of their chemical, mechanical, electrical, and optical properties have led to the investigation of methods for their synthesis at lower cost with enhanced performance for next generation devices. Along with the pursuit of new materials that exhibit properties of interest, industry requires...
Nearly all soils are comprised of mixtures of coarse and fine particles. Behavior under mechanical and thermal loading of soil is strongly influenced, and in some cases governed, by the ratio of coarse to fine particles. A better understanding of the fundamental behavior of soil mixtures will provide insight to...
The fall cone device may be preferable to the Casagrande cup for the determination of liquid limits because it is based on a firm theoretical background and maintains a high degree of operator independence. This makes the fall cone device a superior tool for measuring consistency limits for research and...

Sphaerellopsis filum is a mycoparasite of Puccinia graminis subsp. graminicola, a rust fungus that causes widespread crop damage on perennial ryegrass grown for seed. In observations taken over the winter months, S. filum was found naturally colonizing 2% of P. graminis subsp. graminicola uredinia on first-year plantings and 25% of...

The spatial and temporal variability of nearshore sand bar morphology is quantified using a unique data set
spanning 2 years. The data consist of daily time exposure images of incident wave breaking on an open coast
sandy beach which may be used to infer bar morphology (Lippmann and Holman, 1989)....
A technique is presented to remotely measure the scales and morphology of natural sandbars based
on the preferential dissipation of wind waves and swell over the crests of the bar. Photographic or
video images are recorded and statistical uncertainties associated with incident wave height modulations
removed by averaging (time exposures)....
This study assessed growth, condition, and mortality of residual trees one decade after harvest across three silvicultural treatments in thirty 85- to 125-year-old Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) stands in the Oregon Coast Range foothills. Group-selection cuts had 33% of the entire stand volume extracted as patches approximately 0.2–0.8 ha...
Intraspecific life history attributes of growth, survival, and reproduction can vary in
response to changes in the physical environment. These changes can induce a cascading effect
across trophic levels. In marine systems, shifts in ocean conditions such as warm and cold phases
of ENSO can change primary production in benthic...

This paper presents a parallel implementation and validation of an accurate and efficient three-dimensional computational model (3D numerical wave tank), based on fully nonlinear potential flow (FNPF) theory, and its extension to incorporate the motion of a laboratory snake piston wavemaker, as well as an absorbing beach, to simulate experiments...
1. The evaluation of the age and growth of animal populations is essential for understanding and
predicting how populations will respond to changes in environmental conditions and anthropogenic
stressors.
2. We used a novel, von Bertalanffy hierarchical modelling approach to quantify relationships between
the growth of three freshwater mussel species...
Teen pregnancy is associated with a host of deleterious outcomes for girls such as drug use and poor parenting. Thus, reducing teen pregnancy rates could improve long-term developmental outcomes for girls, improving adjustment during young adulthood. Based on the positive effects of Multidimensional Treatment Foster Care (MTFC) relative to group...
We quantified the patterns in macroinvertebrate assemblages and their
associated environmental gradients from 457 least-disturbed wadeable
stream sites across the 48 contiguous United States sampled as part
of US EPA’s National Wadeable Stream Assessment. The majority of the
variation in assemblage composition at the finest taxonomic resolution
was related to...
Two large-resistance realisation schemes are proposed using switched-capacitor
circuits. The equivalent resistance of the array realisation
increases as the third power of the number of capacitor pairs, and
that of the ladder realisation increases exponentially. The equivalent
resistance for the ladder scheme also grows with the capacitance
ratio. Using these...
