Vertical mergers are mostly perceived in the literature as a way of reducing production and transaction costs.
However, vertical restrictions or raising rivals’ costs (RRC) are taken into great consideration by the antitrust authorities as
potential consequences of vertical integration. The case of the French tuna industry seems of particular...
Natural stream systems contain a variety of flow geometries which contain flow separation, turbulent shear layers, and recirculation zones. This work focuses on streams with dead zones. Characterized by slower flow and recirculation, dead zones are naturally occurring cutouts in stream banks. These dead zones play an important role in...
A study on the effects of light quality and periodicity on the germination of Douglas-fir seed and the growth of Douglas-fir seedlings was conducted. Interest was focused on responses that could be measured and observed without biochemical assay. It was found that .Douglas-fir seed,s would respond to red-light treatments by...
Madagascar is the world, fourth biggest island, and
one of the world‚ poorest countries. Given its severe
poverty, Madagascar has no large-scale domestic fleet. Consequently, it is required by the United Nations
Convention on the Law of the Sea to rent these un-exploited resources to distant water fleets (DWFs)
from...
Fish are marketed with various intermediaries between producers and final consumers. The number and the nature of the intermediaries, market structures at each stage of the value chain and other factors related to the organisation of markets may substantially affect the transmission of information throughout the chain. The present study...
Our paper aims to study the image of the European fisheries sector, as perceived by European citizens. To
our knowledge, no approach has focused on the perceived impact of fishing on the halieutic resources. More precisely, we seek to analyze the perceived impact on the marine environment of fishing activities...
Elevated groundwater nitrate (NO3
-) concentrations in the Southern Willamette
Valley (SWV) caused the Oregon Department of Environmental Quality (ODEQ) to
declare a Groundwater Management Area (GWMA) in Spring, 2004. To better
understand direction of groundwater flow, groundwater age, and nitrate transport
pathways of the SWV we developed a steady-state...
Hyporheic Exchange Flow (HEF) is driven by head gradients defined by the hydro-topography of the stream surface, which is controlled by the particular geomorphology of the stream. We quantified the impact of large wood, which typically exerts a strong control on stream morphology, on HEF in a second order, low...

The exceptional feature of the brushless doubly-fed
machine is the lack of need for frequent replacement of
brushes. The inherent instability of this machine has to be
overcome for its application in adjustable speed drives and
variable speed generation systems.
Specific objectives were:
to study the characteristics of the machine...
Mass transfer processes were evaluated in an artificial, non-uniform porous medium with a power law distribution of diffusion rate coefficients obtained from physical characterization of solute and porous medium. Breakthrough curves of several pulse experiments conducted at different velocities were compared (1) to analytical expressions for concentrations at mass transfer...
A microprogramming teaching tool was designed and implemented. This tool was based on the Am 2900 bitslice microprocessor family. It provides tools for understanding software development for a simple bitslice microprocessor.
An ASR metric and site rating index applied to over 120 municipal and agricultural locations across Oregon, combined with comparison to case study data from existing ASR sites, indicate that more than 50% of selected sites are hydrogeologically suitable for ASR. The ASR metric is a ratio of aquifer storage...
A recent study in agricultural products has brought out evidence of asymmetrical transmission of price changes according to the sign (positive or negative) of past variation. Interestingly, asymmetry was more commonplace for products with a lower elasticity of supply due to the perishable nature of products. A similar study based...
English holly culture in Oregon has been threatened by the
development of red leaf spots which prevent sale of cut holly.
Chemical, mechanical and insect injury and boron deficiency have
been shown in the past to cause different types of red leaf spotting,
but the cause of holly scab, a...
