The word “desertification” was introduced in 1949 by the French scientist Aubreville in his report “Climats, forêts et désertification de l´Afrique tropicale”. The concept, however, was discussed earlier by European and American scientists in terms of increased sand movements, desiccation, desert and Sahara encroachment and man made deserts. Desertification, at the beginning of last century, mea
In Kenya, the government is promoting high-value and drought resistant crop varieties in an effort to reduce poverty in rural areas. Sugar beet is one such crop. This study was conducted with two objectives: 1) to assess the opportunities and challenges for sugar beet cultivation and adoption in the Nyandarua district of Kenya and 2) to assess whether sugar beet adoption can offer an opportunity f
Background: The objective was to investigate in a group of obese subjects the course in skeletal muscle phospholipid (SMPL) fatty acids (FA) during a 24-weeks weight maintenance program, which was preceded by a successful very low calorie dietary intervention (VLCD). Special focus was addressed to SMPL omega-3 FA, which is a lipid entity that influences insulin action. Methods: Nine obese subjects
We report on the multi-wavelength observations of PKS 1510-089 (a flat spectrum radio quasar (FSRQ) at z = 0.361) during its high activity period between 2008 September and 2009 June. During this 11 month period, the source was characterized by a complex variability at optical, UV, and gamma-ray bands, on timescales down to 6-12 hr. The brightest gamma-ray isotropic luminosity, recorded on 2009 Ma
Background High plasma HDL cholesterol is associated with reduced risk of myocardial infarction, but whether this association is causal is unclear. Exploiting the fact that genotypes are randomly assigned at meiosis, are independent of non-genetic confounding, and are unmodified by disease processes, mendelian randomisation can be used to test the hypothesis that the association of a plasma biomar
Background The aim of this study was to investigate gene transfer to human umbilical cord blood (CB) CD34(+)/CD38(low) and NOD/SCID repopulating cells using oncoretroviral vectors and to compare the transduction efficiency using three different viral envelopes. Methods CB cells were transduced on Retronectin using an MSCV-based vector with the gene for GFP (MGIN), which was packaged into three dif
Oxidative addition of the silanes R3SiH (R3= Ph3, Et3, EtMe2) to the unsaturated cluster [Os3(µ-H){µ3-Ph2PCH2PPh(C6H4)}(CO)8] leads to the saturated clusters [Os3(µ-H)(SiR3)(CO)9(µ-dppm)](SiR3= SiPh31, SiEt32 and SiEtMe23) and the unsaturated clusters [Os3(µ-H)2(SiR3){µ3-Ph2PCH2PPh(C6H4)}(CO)7](SiR3= SiPh34, SiEt35 and SiEtMe26). Structures are based on spectroscopic evidence and a XRD structure o
The observation of the electroweak production of a W boson and a photon in association with two jets, using pp collision data at the Large Hadron Collider at a centre of mass energy of s=13 TeV, is reported. The data were recorded by the ATLAS experiment from 2015 to 2018 and correspond to an integrated luminosity of 140 fb-1. This process is sensitive to the quartic gauge boson couplings via the
Purpose: There is mounting evidence that the agrammatism that defines Broca’s aphasia can be explained in processing terms. However, the extant approach simply describes agrammatism as disparate deficits in a static, mature system. This tutorial aims to motivate and outline a developmental alternative. This alternative is processability theory (PT), a root-to-apex theory of language development, w
Research and development is a crucial part of any functioning economy, not the least within the European Union as one of the leading markets in the world today. In addition to providing the market with new products, R&&semicD also introduces better ways of production thereby creating new markets. However, R&&semicD is often a costly and advanced process demanding huge economi
The overall aim of this thesis was to study life satisfaction (LS) and factors associated to LS in the group aged 78 and above. As an aid in interpreting the findings, Baltes’ and Baltes’ theory of selective optimisation with compensation (SOC) was used. All four studies included the same studypopulation who were followed for three years in the study Good Aging in Skåne, a national, randomized, po
In this document, a large number of mathematical models describing various physical, biological and chemical processes in a wastewater treatment plant are presented. In most cases, the models are fairly simple as they are inteded for steady-state simulations based on yearly averages of the influent wastewater charteristics. The combination of models forms a software tool namned URWARE (URban WAter
Popular Abstract in Swedish Affärsklimatet för dagens energimarknad har varit händelserik de senaste två decennierna med introduktaion av den avreglerade elmarknaden och den ökade vikten av miljöfrågor vid design och inköp av energirelaterade anläggningar. Detta har bidragit med krav om nya analyskriterier, vilka inte bara påverkar den tekniska utformningen av komponenter och system, utan även tilThe business climate of the energy market has been eventful over the last two decades, particularly with the introduction of the deregulated electricity market and promotion of environmental issues. This has subsequently lead to new analysis criteria, influencing both technology requirements and production costs. To be able to manage all the questions that have arisen from this the knowledge of th
The objectives of this project were to estimate network-based crash prediction models that will predict the expected crash experience in any given geographic area as a function of the highway link, intersection and land use features observed in the area. The result is a system of GIS programs that permit a polygon to be drawn on a map, or a set of links and intersections to be selected, and then p
The evaporative gas turbine pilot plant (EvGT) has been in operation at Lund Institute of Technology in Sweden since 1997. This article presents the latest development in the evaporative technology, the evaporation of bio-ethanol in a gas turbine power plant as a means to reduce the emission of greenhouse gases. Bio-ethanol is produced from a feedstock consisting of corn-stover, and the bio-ethano
In the light of the environmental challenges society is facing it is important thatboth products and their packaging systems are optimised from an environmental perspective. Previous research highlights that environmental optimisation of packaging requires an integrated assessment of product and packaging together.Theory on green packaging development (GPD) is comprehensive and there areexamples o
Orphan drugs designed to treat rare diseases are often overpriced per patient. Novel treatments are sometimes even more expensive for patients with ultra-rare diseases, in part due to the limited number of patients. Pharmaceutical companies that develop a patented life-saving drug are in a position to charge a very high price, which, at best, may enable these companies to further develop drugs for
All human practices are, ultimately, set and defined by limits; be they social, economic, physical, or environmental. Yet even in the face of such realities, practices which transgress the confines of possibility remain remarkably obdurate. This thesis addresses the issue of one such practice, i.e. the escalation of personal mobility across time and space which pushes above and beyond systemic bou
