Home Dissolution: What Happens After Separation?

Building a home and creating a family are highly interconnected processes. So what happens to the home when people separate or divorce? This paper addresses this question using both a quantitative and a qualitative approach. Based on an extensive database with socio-economic background data of 42 000 separated Danish couples in 2002, the housing careers of both partners were followed to see how the housing situation of different types of people was affected by the separation. In the qualitative approach, nine interviews with couples who had parted shed light on the emotions and practical problems of dissolving a home: how to decide who should stay? Who should move? What was it like to stay alone in, or to leave, the matrimonial home?     

Screening of indoles in cheese

 Indole and skatole (3-methylindole) are formed from tryptophan by microbial activity. Depending on their concentration, they may either contribute to an unpleasant odour, as described for pig meat, or alternatively to a positive aroma profile, as during ripening of cheese. In a screening study, the two indoles in various types of cheese were determined, by both HPLC and GC. It was found that the two compounds mainly occur in mould cheese, such as Camembert and are even more pronounced in blue-veined cheese. The concentrations in unripened cheese were up to 700 ng/g fat for indole and 50 ng/g fat for skatole. The formation of the two indoles increases when proteolysis during ripening provides more tryptophan. Skatole formation appears to be specifically favoured by a low pH and anaerobic conditions.

Effect of the activation procedure on the performance of Mo/H-MFI catalysts for the non-oxidative conversion of methane to aromatics

The effect of pre-treatment on the performance of Mo/H-MFI zeolite catalysts applied to the non-oxidative conversion of methane to aromatics has been investigated. It is demonstrated that catalyst performance depends on activation conditions. Activation of the Mo-oxide/H-MFI precursor with an n-butane/hydrogen mixture results in higher catalyst stability and benzene selectivity which are tentatively attributed to the formation of the -MoC_1−x carbide, with f.c.c. structure as revealed by XRD.     

Two-tier relaxed heaps

We introduce a data structure which provides efficient heap operations with respect to the number of element comparisons performed. Let n denote the size of the heap being manipulated. Our data structure guarantees the worst-case cost of O(1) for finding the minimum, inserting an element, extracting an (unspecified) element, and replacing an element with a smaller element; and the worst-case cost of O(lg n) with at most lg n + 3 lg lg n + O(1) element comparisons for deleting an element. We thereby improve the comparison complexity of heap operations known for run-relaxed heaps and other worst-case efficient heaps. Furthermore, our data structure supports melding of two heaps of size m and n at the worst-case cost of O(min {lg m, lg n}). A preliminary version of this paper [8] was presented at the 17th International Symposium on Algorithms and Computation held in Kolkata in December 2006.

Polymeric thin films of controlled complex refractive index formedby the electrostatic self-assembled monolayer process

This letter reports a method, the electrostatic self-assembled monolayer process, for the synthesis of multilayer thin-film materials with controlled complex refractive index. By incorporating appropriate precursor molecules in each monolayer and organizing the physical order of the multiple monolayers through the material, it is possible to achieve designed complex refractive index properties. In this work, the real part of the refractive index of materials formed by this process was controlled from 1.424 to 1.615, and the imaginary part was controlled from 0.00001 to 0.035, both at a wavelength of 550 nm. To our knowledge, this is the first time that experimental measurements of self-assembled thin films are presented to demonstrate that this method is useful for the design and synthesis of thin films of controllable refractive index
