The T-matrix method is applied to the problem of scattering of Rayleigh-Lamb modes from a twodimensional cavity in an elastic plate. A formal solution is obtained which is valid also for non-planar surfaces. Explicit expressions and numerical results are given for a plate with plane surfaces.

BACKGROUND AND AIMS: Monochromatic pulsating light may have effects on wound healing. In an earlier study of grade II ulcers, there was a tendency toward better healing in the phototherapy group (p=0.06). The present study on patients with grade II ulcers was performed to verify these findings. Data from this study were pooled with data from the earlier study. METHODS: Ninety-four patients were of

Nummer 3 av Naturvetaren innehåller en debattartikel av Ingvar Fogstam: “Vi kan inte stoppa naturliga klimatvariationer”. Den innehåller flera insinuationer och underliga påståenden med anknytning till IPCC-rapporterna.

In the present contribution we review some recent work on scattering of electromagnetic waves from various geophysical targets, by means of P. C. Waterman's approach. As an introduction to the specific applications to be described, a general outline is given of the basic features of this approach, as applied to electromagnetic waves. The algebraic structure of the resulting equations for single an

Software release planning takes place on strategic and operational levels. Strategic release planning aims at assigning features to subsequent releases such that technical, resource, risk and budget constraints are met. Operational release planning focuses on the development of a single software release. Its purpose is to assign resources to feature development tasks such that total release durati

An overview of the work of Swedish filmmaker Carl Slättne (b. 1937) who has been an important part of avant-garde film culture as well as of the documentary tradition within Swedish television.

Why was Scandinavia the first place in the world to introduce national laws allowing registered partnership between same-sex couples? This article is a survey and historical documentation of the registered partnership laws throughout Scandinavia, documenting their origin in Denmark in 1989 and their subsequent adoption by every Nordic country. The origins of the laws are traced to the 1970s

Ischemic stroke causes transient increase of neural stem and progenitor cell (NSPC) proliferation in the subventricular zone (SVZ), and migration of newly formed neuroblasts toward the damaged area where they mature to striatal neurons. The molecular mechanisms regulating this plastic response, probably involved in structural reorganization and functional recovery, are poorly understood. The adapt
