Does expansion of the introduced Manila clam Ruditapes philippinarum cause competitive displacement of the European native clam Ruditapes decussatus?
(Elsevier, 2013-05-03)
In several estuaries or lagoons of Europe the introduced Manila clam Ruditapes philippinarum has supplanted the native grooved carpet shell clam Ruditapes decussatus by occupying almost entirely its ecological niche and ...
LARVAHS: Predicting clam larval dispersal and recruitment using habitat suitability-based particle tracking model
(Elsevier, 2013-09-13)
We herein explore the potential larval dispersal and recruitment patterns of Ruditapes decussatus and Ruditapes philippinarum clams, influenced by larval behavior and hydrodynamics, by means of a particle-tracking model ...
Catalytic Enantioselective Synthesis of Tertiary Thiols From 5H-Thiazol-4-ones and Nitroolefins: Bifunctional Ureidopeptide-Based Brønsted Base Catalysis
(WILEY-VCH Verlag, 2013-09-17)
The direct catalytic reaction between an enolizable carbonyl compound and an electrophile under proton-transfer conditions has emerged as a challenging versatile transformation in organic synthesis.1 Over the last years ...
Use of native species to improve carbon sequestration and contribute towards solving the environmental problems of the timberlands in Biscay, northern Spain.
(Elsevier, 2013-03-15)
The rapid transformation of natural forest areas into fast-growing exotic species plantations, where the main objective is timber and pulp production, has led to a neglect of other services forests provide in many parts ...
Selecting random parameters in discrete choice experiment for environmental valuation: A simulation experiment
(Elsevier, 2013-06-03)
This paper examines two tests commonly used to select random parameters in choice modelling: the Lagrange Multiplier (LM) test as proposed by McFadden and Train (2000) and the t-statistic of the deviation of the random ...
Can understorey native woodland plant species regenerate under exotic pine plantations using natural succession?
(Elsevier, 2013-08-26)
Forestry industry in many European countries has begun to focus on sustainable forest management practices, and consequently, a greater emphasis is now being placed on the restoration and enhancement of native woodlands ...
Flicker Characteristics of Efficient Lighting Assessed by the IEC Flickermeter
(Elsevier, 2013-10-13)
We present an experimental study of the behavior of modern lighting technologies
under supply voltage fluctuations. Some studies have reported that flicker severity
measurements could exceed the compatibility levels ...
Experimental verification of the anomalous skin effect in copper using emissivity measurements
(AIP, 2013-06-20)
Spectral directional emissivity has been measured in copper between 3 and 24 μm above room temperature. The experimental spectrum shows a weak broad peak between 7 and 14 μm, which is much more acute for higher emission ...
Calibration patterns for predicting residual strengths of steel fibre reinforced concrete (SFRC)
(Elsevier, 2013-11-12)
Steel Fibre Reinforced Concrete (SFRC), a composite construction material, needs reliable prediction and control techniques to promote its use in structural applications. The distribution and orientation of fibres within ...
First spectral emissivity study of a solar selective coating in the150–600 ºC temperature range
(Elsevier, 2013-07-20)
A complete experimental study of temperature dependence of the total spectral emissivity has been performed, for the first time, for absorber–reflector selective coatings used in concentrated solar power (CSP) systems for ...
