Popular Abstract in Swedish Baserat på ett nytt data material bestående av observationer på 16 variabler i 232 val i Afrika, görs tre olika analyser. Först avvisas ett antal etablerade hypoteser om nutida Afrikansk politik och demokratisering. Sedan påvisas valens självförstärkande och självförbättrande kraft med hänvisning till institutioners interna logik och strukturering av aktörers incitamenThis book is about elections and democracy in newly democratizing countries. Building on a new data set of 5,568 observations in 232 elections, it provides evidence elections have a casual impact on improving the quality of democracy in Africa in more than one way. The study demonstrates multiparty elections do not signal the end of transitions to democracy but rather foster liberalization and hav

The smoothness-constrained least-squares method is widely used for two-dimensional (2D) and three-dimensional (3D) inversion of apparent resistivity data sets. The Gauss-Newton method that recalculates the Jacobian matrix of partial derivatives for all iterations is commonly used to solve the least-squares equation. The quasi-Newton method has also been used to reduce the computer time. In this me

Optical region spectra of 31 HgMn stars have been studied for the abundance and isotope mixture of mercury. In the course of the investigation the lines Hg I lambda 4358 and Hg Ii lambda lambda3984,6149 have been studied, with abundances established for all three lines in several HgMn stars. The mercury isotope mixture has been determined from high resolution spectra of the lambda 3984 line.Possib

The middle Cambrian -Furongian transitional interval was a time of significant biotic and environmental changes. Strata of this age in Scania, southern Sweden, contain two interlayered biofacies, a normal one dominated by trilobites and an anomalous one dominated by phosphatocopines (small bivalved arthropods). In places these biofacies are separated by intervals barren of fossils. In a phosphatoc

We calculate the one-loop effective action of the SU(2) Yang-Mills theory for center-vortex configurations, both in 3D and 4D. We find that in both cases there are minima of the effective action, corresponding to vortices of the transverse size approximately 4/g(3)(2) and 1.7/Lambda((MS) over bar), respectively. The values of the effective actions at the minima are negative, suggesting that the Eu

The E-GIS project partnership comprised 10 partners (universities, organisations and private bodies) from 6 European countries; Bulgaria, Lithuania, The Netherlands, Norway, Portugal and Sweden. The E-GIS project was initiated in order to: • Establish competent nettworks between universities and private bodies for cooperation on an European level within the GIS area – both for this project and fo

Theories of democracy consider communicative interaction among citizens central, In recent years the idea of deliberative democracy has galvanised elements of political theory with perspectives on communication. This concept emerges to a large extent from the Habermasian trajectory and links currents from theories of civil society and citizenship. It has thus a rather forceful normative dimension.

Popular Abstract in Swedish Gangesfloden i Varanasi (Indien) anses samtidigt vara fullkomligt ren och svårt förorenad, beroende på vem som definierar dess egenskaper, brahminska religiösa specialister eller vetenskapligt orienterade miljöaktivister. Medan kontroversen fortgår, försöker några hinduiska religiösa ledare att anpassa sina traditioner till de nya miljöparadigmen, och deras förhållningsWhether the Ganges river in Varanasi (India) is pristinely pure or heavily polluted depends on by whom it qualities are defined, the Brahmin religious specialists in the city or the science oriented environmentalists. While the controversy continues, some Hindu religious leaders are searching for ways to adjust their respective traditions to the environmental paradigms, an initiative that reflects

The mechanical design of the EUROBALL neutron wall and neutron detectors, and their performance measured with a Cm-246,Cm-248 fission source are described. The array consists of 15 pseudohexaconical detector units subdivided into three, 149 mm high, hermetically separated segments and a smaller central pentagonal unit subdivided into five segments. The detectors are filled with Bicron BC501A liqui

We have identified a novel protein, Leprecan-like 1 (LEPREL1), with profound similarity to the Leprecan family of proteoglycans. The genomic organization of the Leprecan gene family was found to be highly conserved. Expression analysis shows that LEPREL1 is expressed in most tissues as a 3.4 kb transcript encoding an 80 kDa protein. A LEPREL1 specific antibody stains many cell types including adip

Retinitis Pigmentosa (RP) is a group of uncured retinal diseases with the world wide incidence of about 1/3500. In spite of the huge efforts in past years, the mechanisms underlying this type of hereditary blindness has not been elucidated and nor any effective treatment available. The rd1 mouse strain carries a mutation in ?-subunit of phosphodiesterase gene which hydrolyzes the cGMP and is need

The effect on haemostatic variables by dextran 70, enoxaparin and their combinations, given in doses of 500 ml i.v. and 40 mg s.c. respectively, was studied in a randomised cross-over fashion in twelve healthy male volunteers. Antifactor-IIa activity, antifactor-Xa activity, APTT, factor VIII, vWF, bleeding time and blood counts were analysed over a 24-h period. Dextran alone did not affect antifa

Popular Abstract in Swedish Parkinsons sjukdom (PS) karaktäriseras av långsam celldöd i hjärnan och gradvis uppträder minskad rörlighet och muskelstelhet som mest framträdande symptom. PS drabbar ungefär 0.1% av befolkningen, och inträder oftast i femtio- till sextioårsåldern. Varför sjukdomen uppkommer är till stor del okänt, men man vet att de dopamin producerande cellerna i mitthjärnan (särskilParkinson's disease (PD) is a common neurodegenerative disorder characterized by motor deficits. Levodopa treatment provides marked symptomatic relief. However, within 5-10 years after the start of Levodopa treatment, most PD patients display a gradual loss of drug efficacy. Importantly, the neuropathology of PD is dominated by a marked loss of dopaminergic neurons located in the substantia nigra.

Purpose: We tested the biocompatibility of nitinol, a nickel titanium alloy, and stainless steel (SS) as bladder implant materials. Materials and Methods: Rats received a nitinol implant, an SS implant or were sham controls. Two, 3, 6 and 8 weeks following implantation 24-hour voiding behavior studies were per-formed to investigate bladder irritation. All animals were sacrificed 8 weeks after impl

Lake Poopo, within the large Altiplano basin of Bolivia, is connected upstream to Lake Titicaca and downstream to the salares, the big salt fields. Small changes in precipitation and river inflows strongly affect the extent of the lake surface area. For times when there are no satellite images, it is difficult to determine the extent of the lake from observations. Water balance computations were p
