Exposed limestone cliffs in the Swiss Jura Mountains harbour a diverse lichen community with some rare species. Sport climbing has recently increased in popularity on these cliffs. We examined the effect of sport climbing on calcicolous lichens by assessing species diversity and cover of lichens in climbed and unclimbed areas of 10 isolated cliffs in the northern Swiss Jura Mountains. We also inve

The academic discourse on the need for a shared political public sphere at the level of the European Union has in recent years produced the conventional wisdom that an emerging transnational community of communication is already observable in the mass media. However, the empirical indicators on which this notion rests tend to accommodate parallel national public spheres rather than a genuine trans

Boken är utgiven med anledning av Lars-Erik Nevanders 70-årsdag och baseras på ett symposium i Lund 1991 med föredrag av personer som arbetat med Nevander under hans tid som professor i Lund. Föredragen hölls av en bred samling internationella namn och omfattar ett brett spektrum bl a klimat & fuktfrågor, betong- och murverkskonstruktioner m.m.This book is dedicated to Lars Erik Nevander, who turned 70 in the autumn of 1991. An international symposium was held in Lund in September of 1991 to which participants were specially invited who had worked with Lars Erik Nevander in one connection or another during the time of his professorship at Lund University. Invited papers presented by some 20 of the participants illurninated important d

Mineral magnetic properties and the carbon content of a sediment sequence in Lake Kullatorpssjon on the Kullen Peninsula in northwest Scania, southern Sweden, were investigated. Diatom and ostracod analyses were undertaken for palaeoecological reconstruction and a chronology was constructed from accelerator mass spectrometry (AMS) radiocarbon dating of terrestrial plant remains and mosses. Five st

The purpose of this study was to describe, and analyse the effect of an intervention on, the biomechanical workload in the neck and shoulder region of female hairdressers. Arm elevation was measured by inclinometers and muscular load of m. trapezius by electromyography. The intervention comprised working technique recommendations, e.g. to work with less elevated arms and more relaxed muscles. The

Popular Abstract in Swedish Inom forskningen kring rengöring och processhygien är det viktigt att förstå de bakomliggande mekanismerna för depositionen av partiklar och makromolekyler på ytor. Depositionsprocessen kan beskrivas som transporten av partiklar till ytan och den påföljande adhesionen. Om de hydrodynamiska krafterna är tillräckligt starka kan partiklarna åter transporteras bort från ytaIn the research area of cleaning and process hygiene it is important to understand the underlying mechanisms behind the deposition of particles and macromolecules onto surfaces. The deposition process is described as the transport of particles to the surface followed by attachment. If the hydrodynamic forces are strong enough, the particles can be re-entrained. In this work particle deposition wa

n this paper we introduce the Mean Effective Radiated Power (MERP) and the Mean Effective Radiated Sensitivity (MERS) as alternative figures of merit of the uplink and downlink communication performance of wireless handheld terminals. We show how they are related to the Mean Effective Gain (MEG), the total radiated power (TRP) and total receiver sensitivity (TRS).

In the study presented in this paper, the effect of different vehicle driving cycles on the pneumatic hybrid has been investigated. The pneumatic hybrid powertrain has been modeled in UT-Power and validated against experimental data. The GT-Power engine model has been linked with a MATLAB/simulink vehicle model. The engine in question is a single-cylinder Scania D12 diesel engine, which has been c

In 2000, the African Growth and Opportunity Act was signed into law in the United States, and is at present set to last until 2015. The act aimed at helping the Sub-Saharan African countries develop “through trade, not aid”. This essay studies the effect of the act on diversification of goods exported from these African countries to the United States. By analysing trade data for the period 1997-20

Collective action can be challenging in the governance of common pool resource. While social learning has the potential to facilitate negotiations and communications, power imbalance can still challenge the common pool resource (CPR) governance. In an attempt to study collective action in that context, I undertook a qualitative case study at the Cañete basin, Peru. The primary data was manly colle

Since the year 2000, achieving the Millennium Development Goals (MDGs) has become the central focus of the international community. Using an empowerment framework, this study assessed the impacts of the four projects associated with Poverty Reduction Strategy Papers (PRSPs) or its Nigerian blueprint, National Economic Empowerment and Development Strategy (NEEDS). It gathered data with semi-structu

The impact of microcredit on women’s empowerment remains debated. While some studies suggest that microcredit helps women increase their income earning abilities, leading to greater power within the household, others argue that men often take control over the microcredit allocated to women, which leads to a more vulnerable position within the household for women. This paper evaluates the impact of
