1. INTRODUCTION Geographers at the University of Lund have been active in research on desertification/ land degradation and environmental change monitoring of African drylands since the mid 1970’ies and of Asian drylands since the beginning of the 1990’ies. The results obtained so far do not confirm the concept of desertification as a mainly man made phenomena but indicate that the importance of c

Popular Abstract in English The thesis that you are reading at this moment was printed using climate compensated paper, a sign that consciously or not you are contributing somehow to control the current environmental issues in our planet. It would not be nice if every single article used in your daily life contains information about how environmentally friendly that product is? We have to think “bOxidation reactions are important in organic chemistry as well as in nature. In industry, oxidations are commonly used for the synthesis of chemicals and pharmaceuticals, however such processes have a number of limitations, they use chlorinated solvents, stoichiometric oxidation reagents, and in some cases the reagents that have risks of explosion during transportation and storage. This has called

The production of ethanol based on lignocellulosic biomass requires the fermentation of a hydrolysate containing hexose and pentose sugars in an inhibitory environment. In fact, the lignocellulosic hydrolysate obtained from pretreatment and hydrolysis of the raw material contains a variety of inhibitory compounds, including (i) the furaldehydes 5-hydroxymethyl-2-furaldehyde (HMF) and 2-furaldehyde

Three titania polymorphs, anatase, rutile, and TiO2(B), were used as supports for vanadia. Catalysts with nominal loadings corresponding to 1.5 and 5 theoretical layers were prepared. True monolayer samples were obtained by NH3(aq)-treatment of the samples with 5 nominal vanadia layers. Prepared catalysts were characterized by chemical analysis, ESR, and high-resolution electron microscopy. It was

Popular Abstract in English The food we consume is hardly, if ever, sterile. From fresh produce to processed products, foods harbor one or more types of microorganisms. The presence of some ‘beneficial’ microorganisms is desirable in food production, because they contribute to the characteristics of the final product, as, for example, in the production of wine, beer or cheese. In other cases, micrControl of the dissemination of pathogens in the food production chain is an on-going process with new challenges emerging as pathogenic bacteria evolve and express enhanced virulence characteristics. Staphylococcus aureus and Listeria monocytogenes are two notorious pathogens responsible for staphylococcal food poisoning (SFP) and listeriosis: a foodborne intoxication and an infectious disease re

The aim of this work is to propose a framework for providing QoS routing in MANETs. The proposed framework uses local information of nodes such as node's speed, buffer, and power to select path for routing. Deploying these information, more stable paths are selected and hence QoS routing parameter could be satisfied. Moreover, routing performance has been improved, especially in terms of end-to-en

A comparative experimental investigation has been performed, comparing the emissions from a synthetic jet fuel and from Jet AI. In the investigation, the unburned hydrocarbons were analyzed chemically and the regulated emissions of NOX, CO and HC were measured. All combustion tests were performed under elevated pressures in a gas turbine combustor rig. A Swedish company, Oroboros AB, has developed

Popular Abstract in Swedish Cancer är på cellnivå en genetisk sjukdom, i det avseendet att typiska egenskaper för cancerceller, t ex okontrollerad celldelning samt abnorm känslighet för yttre regulatoriska signaler, uppkommer genom förvärvade och ibland ärftliga förändringar, s k mutationer, i cellens arvsmassa. Hur mutationerna uppstår är bara till viss del känt. Somliga förändringar beror på strAcquired genetic alterations, of which many are visible on the chromosome level, are believed to be necessary for tumorigenesis, and most tumors display characteristic patterns of recurrent structural and numerical aberrations. However, two of the most frequently occurring chromosome mutations in malignant and benign solid tumors, i.e., trisomy 7 and rearrangements of 12q13-15, have recently been

Green products are becoming part of contemporary consumer cultures and part of everyday life. But how are green products constructed? And how do they work? This paper is concerned with the role that marketing plays in the making and circulation of green products. My aim is to illuminate the process of green making. Departing from an understanding of marketing as socio- material practice I analyse

Vi löper ofta risker som vi inte tar. Och vi vet ofta litet om de situationer där vi tar risker. Dessa två iakttagelser utgör den här bokens utgångspunkter. Det är utgångspunkter som inte passar så väl ihop med mycket annat som vi brukar ta för givet i risksammanhang. Läsaren får därför många tillfällen att ompröva sin syn på saker som skillnaden mellan fara och risk, vad ett riskobjekt är och vad

In trying to get products out to market, manufacturers of FMCG (Fast Moving Consumer Goods) differentiate themselves through e.g. promotional efforts and display packaging (Point-of-Purchase packaging). For the display packaging, companies turn to contract packagers who are able to supply this service, providing the design, manufacturing and assembly and packing of the display packaging. This pape

This book examines some of the economic, political and social issues facing the Scandinavian countries of Sweden, Finland, Norway and Denmark. Topics discussed in this compilation include Denmark's energy sector transition toward agro-biomass; Sweden's exchange-rate volatility trade with Germany; Norwegian quota reform in gender corporate representation; legislation, culture and development of qua

Purpose: Supply chain efficiency (economic and ecological) is affected by packaging design. The purpose of this research is to investigate how integrated approaches aiming for ecoefficient supply chains are used in packaging development processes and how a set of preselected factors influences the adaption of more or less integrated approaches at companies. Design/methodology/approach: The researc

Popular Abstract in Swedish Richard Hughes (1900-1976) blev mycket känd genom sin debutroman A High Wind in Jamaica, 1929. Han förhastade sig inte med nästa roman, In Hazard; den kom först 1938. Intervallerna blev allt längre. The Fox in the Attic från 1961 inledde hans romancykel The Human Predicament, och fortsättningen kom med The Wooden Shepherdess 1973. Av en planerad tredje del publicerades The two last novels by Richard Hughes (1900-1976), the first in his planned The Human Predicament series, are partly set in Germany in the years between the First and the Second World War. Much of the action in The Fox in the Attic (1961) takes part in and around Munich, culminating in a fictional reconstruction of the so-called Hitler Putsch on November 8-9, 1923, the future dictator's aborted ea
