Mathematical aspects of an exactly solvable inflationary model
No full textThe inflationary scenario is nowadays the most natural and simple way to solve the problems of the standard Friedmann-Lemaitre-Robertson-Walker cosmology. Generally, inflation is driven by models of gravity minimally coupled to a scalar field φ rolling on a suitable potential V (φ). We discuss a particular model presenting two scenarios: The vacuum universe and the matter-filled universe, in order to find exact general isotropic and homogeneous cosmological solutions displaying an inflationary behavior at early times and a power-law expansion at late times
Author Meets Reader: Not the Marrying Kind: A Feminist Critique of Same-Sex Marriage
No full textThis is an audio recording of an author meets reader session held at the SLSA Annual Conference, University of York, 27 March 2013. Nicola Barker's book, Not the Marrying Kind: A Feminist Critique of Same-Sex Marriage, was the winner of the 2013 Hart SLSA Book Prize. In the session she introduces the book and then engages in discussion about it with Daniel Monk
South Thompson Valley and Pinantan official settlement plan.

Rural Residential Study
No full textThe Thompson-Nicola Regional District has recently been grappling with some of the basic problems and conflicts of trying to provide for rural residential lot demand and, at the same tie, trying to protect the resources, aesthetics and social climate of existing rural area.Not peer reviewedstudydraf
Properties of solutions to porous medium problems with different sources and boundary conditions
No full textIn this paper, we study nonnegative and classical solutions u=u(x,t) to porous medium problems of the type where is a bounded and smooth domain of RN, with N1, I=(0,t) is the maximal interval of existence of u, m>1 and u0(x) is a nonnegative and sufficiently regular function. The problem is equipped with different boundary conditions and depending on such boundary conditions as well as on the expression of the source g, global existence and blow-up criteria for solutions to (?) are established. Additionally, in the three-dimensional setting and when blow-up occurs, lower bounds for the blow-up time t are also derived
Demonstration of a photonic integrated network-on-chip with multi microrings
No full textA multi-microring network-on-chip for datacom applications is demonstrated on a silicon-on-insulator platform. Measurements on the photonic integrated circuit are in good agreement with simulations, achieving a 3dB-bandwidth of 39 GHz and a worst-case crosstalk of -12d
The Role of Coordination and Cooperation for Bt-maize cultivation in Brandenburg, Germany
No full textSince 2006, several varieties of transgenic Bt-maize are approved for commercial cultivation in Germany. The German regulatory framework for growing these crops comprises ex-ante regulations as well as ex-post liability rules to protect conventional and organic farming from possible negative side effects of transgenic plants and to ensure co-existence. Public regulation is also suspected to impose additional costs to those farmers who intend to plant Bt-maize. We address the question how Bt-maize growing farmers perceive the additional costs of regulation and whether coordination or cooperation takes place in order to diminish these costs. In 2006, we carried out a case study in the Oderbruch region (Brandenburg, Germany) comprising eight Bt-maize growing farmers and six adjacent neighbours. The predominantly large farms chose intrafarm coordination to manage the construction of buffer zones within their own fields and to avoid the planting of Bt-maize close to their neighbours. Inter-farm coordination or cooperation with adjacent farmers was not regarded necessary to achieve co-existence.Coordination, Cooperation, Bt-maize, Crop Production/Industries,
