In this paper we consider the nonlinear wave equation problem utt −B ` ‖u‖0, ‖ur‖0 ́ (urr + 1 r ur) = f(r, t, u, ur), 0 < r < 1, 0 < t < T, ̨̨ lim r→0+ √ rur(r, t) ̨̨ <∞, ur(1, t) + hu(1, t) = 0, u(r, 0) = e u0(r), ut(r, 0) = e u1(r). To this problem, we associate a linear recursive scheme for which the existence of a local and unique weak solution is proved, in weighted Sobolev using standard compa...

Blackening was observed on the surfaces of Mesopotamian clay tablets from Umma, Dilbat, Larsa, Ur, Babylon, Uruk, Sippar, and Nippur produced between the Third Dynasty of Ur and the Early Achaemenid Dynasty. Portable X-ray fluorescence analysis revealed that manganese was concentrated on the blackened surfaces. Rod-shaped materials with a length of 100 200 nm and a width of 30 nm were observed ...

2 The North-South discussion paper series produced by the Wageningen UR North-South Centre is a working paper series that aims at stimulating debates on overarching development issues related to the Wageningen UR areas of nutrition and health, sustainable agrosystems, a viable environment and processes of social change. The papers introduce fresh insights into existing debates or present new pr...

We show how the supersymmetric KdV equation can be obtained from the self–duality condition on Yang–Mills fields in four dimension associated with the graded Lie algebra OSp(2/1). We also obtain the hierarchy of Susy KdV equations from such a condition. We formulate the Susy KdV hierarchy as a vanishing curvature condition associated with the U(1) group and show how an Abelian self–duality cond...

The mechanisms underlying learning in classical conditioning experiments play a key role in many learning processes of real organisms. This paper presents a novel computational model that incorporates a biologically plausible hypothesis on the functions that the main nuclei of the amygdala might play in first and second order classical conditioning tasks. The model proposes that in these experi...

The mission of Wageningen UR (University & Research centre) is ‘To explore the potential of nature to improve the quality of life’. Within Wageningen UR, nine specialised research institutes of the DLO Foundation have joined forces with Wageningen University to help answer the most important questions in the domain of healthy food and living environment. With approximately 30 locations, 6,000 m...

A new class of superconductors with the gap function odd under time reversal is considered. Some of the physical properties of these superconductors such as the Meissner effect, composite condensate, gapless spectrum and transition from the odd gap superconductor to the BCS state at lower temperatures are discussed.

Dr. Hans Mol is senior scientist at RIKILTWageningen UR Introduction Regulatory authorities throughout the world set and enforce strict limits on the maximum residue levels (MRLs or tolerances) of pesticides permitted on food and feeds. It falls to analytical laboratories to test these products and ensure they meet the relevant standards. The analytical challenge is to look for over 1,500 poten...
