Evolution from spherical single-particle structure to stable triaxiality at high spins in Nd-140

The level structure of Nd-140(60)80 has been established up to spin 48 by in-beam gamma-ray spectroscopy by use of the Zr-96(Ca-48, 4n) reaction. High-fold gamma-ray coincidences were measured with the EUROBALL spectrometer. Twelve new rotational bands have been discovered at high spins. They are interpreted as being formed in a deep triaxial minimum at epsilon(2) approximate to 0.25 and gamma app

Layover Solution in Multibaseline InSAR Using Robust Beamforming

In this work, we examine how to reliably exploit baseline diversity of a multichannel interferometric SAR system to overcome the layover problem. The problem arises when different height contributions collapse in the same range-azimuth resolution cell, due to the presence of strong terrain slopes or discontinuities in the sensed scene. Several multilook approaches have recently been suggested to c

Property-close Collection of Fat, Oil and Grease (FOG) from Households. – Experiences from a Swedish Case Study.

Problems related to content of fat, oil and grease (FOG) in wastewater is an increasing problem in Sweden. FOG can cause clogging in the sewage system and subsequent flooding and disturbance of processes in waste water treatment plants. The problem has previously been mostly been related to release of large quantities of FOG from restaurants and large scale industries which has caused problems in

Utvärderaren, de utvärderade och den värderande texten

Utvärderingar framställs som attraktiva och oundgängliga samtidigt som det förekommer begränsad kunskap om deras faktiska relevans och om utvärderares arbete. Utvärdering är numera såväl ett självständigt forskningsområde med en vetenskaplig och disciplinär utveckling som en praktik som bedrivs av forskare med vetenskapliga ambitioner, konsulter som arbetar på uppdrag och medarbetare inom organisa

Membrane-based sample pre-treatment strategies in ultra-trace determination of metal ions in complex matrices

Popular Abstract in Swedish I denna avhandling har olika analytiska provupparbetningsmetoder för bestämning av spårmetaller i komplexa matriser utvecklats och testats. I metod utvecklingen har både porösa och icke-porösa membraner använts för provrening och anrikning före slutanalys med atom absorptions spektrometri (både med flamma och grafitugns tekniken) och stripping voltammetri. De metaller In the present thesis, analytical sample pre-treatment methods for the determination of trace metal ions in complex matrices were developed and tested. These methods were based on membrane fractionation, clean-up and enrichment of analytes and applied to the determination of aluminium, cadmium, cobalt, chromium, copper, nickel and lead in biological and environmental samples. In one application d
