Three strains of brook trout Salvelinus fontinalis (domestic [D], Laval [L], and Rupert [R]) and their reciprocal hybrids were reared from 7 to 21 months of age in three different environments (indoor, constant temperature conditions; indoor, seasonal temperature variations; and outdoor, seasonal temperature variations) to test for the occurrence of heterosis in important life history traits of...

This paper explores the dynamics of value distribution within a sector. It provides exploratory quantitative evidence on how conditions within the segments of a sector’s value chain affect the relative profitability of those segments. We consider how value shifts from one part of the value chain to another by linking two different but causally connected levels of analysis: the inequality of cap...

In the current study,120 rats were divided into six equal groups, including; Group 1: neither irradiated nor treated with ßcarotene (control group), Group 2: given ßcarotene in a concentration of 8 mg/kg body weight/day for a period of 14 consecutive days, Group 3: irradiated through whole body exposure to γ rays (6.5 Gy) single dose, Group 4: given ßcarotene as group 2 then irradiated as group...

Uncertainty over future output prices or input costs can affect investment by a riskneutral firm in two opposing ways. First, it can increase the value of the marginal unit of capital, which leads to more investment. This only requires that the stream of future profits generated by the marginal unit be a convex function of the stochastic variable; by Jensen's inequality, the expected present va...

The de novo domestication has the potential to rapidly capitalize on desirable traits of wild plants. In this issue Cell, Yu et al. report a route an allotetraploid rice, heralding creation novel staple food crop support global security. Domestication crops is major historical innovation that enabled development large complex civilizations. Domesticated were selected for related plant productiv...

The SEDO project develops a platform combining fast access, user freedom, and coherence of the results for presenting complex socio-economic data. As an initial yield, this joint project involving two research actors of Luxembourg, the CEPS/INSTEAD for the content and the CRP-Gabriel Lippman for the technical realization, will deliver on the Net the results of longitudinal surveys about the lif...

Despite the importance of the Newsvendor model, little attention has been paid to its robustness with respect to the estimation of one of its inputs, the salvage value. This oversight is inappropriate because we show that the performance of the Newsvendor model is quite sensitive to the particular method chosen to estimate the salvage value. We highlight two reasons for this sensitivity: small ...

In this paper the authors experiment with multi-display mobile applications that can be used in an environment where multiple smart phones are co-located within the same physical space. Utilizing Remote User Interface interaction metaphor and the REST architectural style they propose a solution that follows the Remote ModelView-Controller model, in such a way that client devices do not need to ...

“Plants Are Smarter Than We Thought” was the headline news recently in a leading journal (Science News, March 6, 2014; http://news.sciencemag.org/signal -noise/ 2014/03/plants-are-smarter-we-thought), highlighting an article published elsewhere (Meyer et al., 2014), which presented evidence that plants are able to make smart decisions in response to predation and environment. Plants are well kn...
