The recent phenomenon of large-scale acquisition of land for a variety of investment purposes has raised deep concerns over the food security, livelihood and socio-economic development of communities in many regions of the developing world. This study set out to investigate the food security outcomes of land acquisitions in northern Sierra Leone. Using a mixture of quantitative and qualitative res
Neuronal function depends on the properties of the synaptic inputs the neuron receive and on its intrinsic responsive properties. However, the conditions for synaptic integration and activation of intrinsic responses may to a large extent depend on the level of background synaptic input. In this respect, the deep cerebellar nuclear (DCN) neurons are of particular interest: they feature a massive b
In addition to having constitutive defence traits, many organisms also respond to predation by phenotypic plasticity. In order for plasticity to be adaptive, induced defences should incur a benefit to the organism in, for example, decreased risk of predation. However, the production of defence traits may include costs in fitness components such as growth, time to reproduction, or fecundity. To tes
Charged-particle production was studied in proton-proton collisions collected at the LHC with the ALICE detector at centre-of-mass energies 0.9 TeV and 2.36 TeV in the pseudorapidity range vertical bar eta vertical bar < 1.4. In the central region (vertical bar eta vertical bar < 0.5), at 0.9 TeV, we measure charged-particle pseudo-rapidity density dN(ch)/d eta = 3.02 +/- 0.01(stat.)(-0.05)(+0.08)
The move towards fire performance-based design in building and transport regulations has led to an increased use of fire models. This increased use of these models and the evolution of different regulations have put higher demands on the predictive capability of fire models. The purpose of this paper is to give an overview of different activities relating to the validation and verification of comp
Inom ramen för det svenska forskningsprojektet Taktik och metodik vid brand i undermarksanläggningar har ett enkelt planeringsverktyg utvecklats som bl a erbjuder stöd till beslutsfattare involverade i planeringen av räddningsinsatser i väg- och järnvägstunnlar. Verktyget, som har utvecklats vid Lunds universitet, heter TuFT och är en förkortning av Tunnel Fire Tools. TuFT kan beskrivas som ett myWithin the Swedish research project Rescue tactics and methodology during fires in underground facilities, a simple decision support tool has been developed. The tool can, for example, aid decision makers involved in the early phase of road and rail tunnel fire risk assessments. The tool has been developed at Lund University and has been termed TuFT, which is an abbreviation for Tunnel Fire Tools.
We aim to provide a long-term ecological analysis of land-use and floristic diversity in the transition from traditional to modern land-use management in the time a.d. 1800-2008 in southern Sweden. We use the Regional Estimates of Vegetation Abundance from Large Sites (REVEALS) model to quantify land-cover changes on a regional scale at 20-year intervals, based on the fossil pollen record. Florist
The effect of glucose and oxygen limitation on the growth and fermentation performances of Dekkera bruxellensis was investigated in order to understand which factors favour its propagation in ethanol or wine plants. Although D. bruxellensis has been described as a facultative anaerobe, no growth was observed in mineral medium under complete anaerobiosis while growth was retarded under severe oxyge
Background: PhiC31 integrase facilitates efficient integration of transgenes into human and mouse genomes and is considered for clinical gene therapy. However recent studies have shown that the enzyme can induce various chromosomal abnormalities in primary human embryonic cells and mammalian cell lines. The mechanisms involved are unknown, but it has been proposed that PhiC31 attachment sites in t
Background: Amyloidosis is a heterogeneous disease caused by deposition of amyloid fibrils in organs and thereby interfering with physiological functions. Hardly any incidence data are available and most survival data are limited to specialist clinics. Methods: Amyloidosis patients were identified from the Swedish Hospital Discharge and Outpatients Registers from years 2001 through 2008. Results:
The authors present fabrication and electrical measurements of InSb nanowire field-effect transistors (FETs) and quantum dots. The devices are made on a SiO2-capped Si substrate from InSb segments of InAs/InSb heterostructured nanowires, which are grown by metalorganic vapor phase epitaxy. For the FETs, both single- and dual-gate devices are fabricated. The Si substrate is employed as the back gat
Purpose The purpose is to examine various aspects of integration in order to structure and define the concept of supply chain management integration. Design/methodology/approach The study is based on an extensive literature review in three steps and a series of interviews with leading SCM consulting firms. Findings We found limited empirical research discussing SCM integration beyond the dyadi
The clover seed weevils Apion fulvipes Geoffroy, 1785 and Apion trifolii L., 1768 (Coleoptera: Apionidae) cause major losses to seed production of white clover (Trifolium repens L.) and red clover (Trifolium pratense L.), respectively. Clover is important as animal forage and an alternative to inorganic fertilizers. Because clover is mainly pollinated by bees, the use of insecticides in management
A functionally normal TP53 is essential to protect organisms from developing cancer. Somatic mutations in the gene represent one of the highest recurring perturbations in human tumours, including colorectal cancer (CRC). However, the variegated phenotype of wide spectrum of somatic mutations in TP53 and the complexity of the disease prevent a straight interpretation of the mutational analysis in t
The chapter by definition focuses on Swedish research and treatment practice in the area of comorbiditity. Three “ethiological” lines of comorbidity is outlined. it thus seems warranted to look upon patients with a precipitating psychiatric diagnosis and a consequent problem of alcohol and/or substance abuse as one specific model/type (1). A second type representting the drug and substance depende
Popular Abstract in Swedish Signalen som registreras under ett arbets EKG prov kan innehålla viktig information rörande hjärtats kondition. De störningar som ofta uppträder i signalen kan dock försvåra en korrekt diagnos. I avhandlingens första del används tidsserie modeller för att skatta profilen, den del av signalen som härrör från hjärtats elektriska aktivitet. Målet med dessa metoder är att The analysis of the recorded electrical activity of the heart during an exercise test is a valuable method for investigating a patient's circulatory and respiratory system. But the disturbances that occurr during a test often make it difficult to interpret the signal in order to detect changes evoked by the increased workload and related to for instance coronary artery diseases. Suppression of dis
This thesis concerns the Large Eddy Simulation methodology and its application to predict complex turbulent flows at high Reynolds numbers, and at times also with high Mach numbers. The meaning of the word ?complex? refers both to the presence of complex flow phenomena and the, often, complex geometry of man-made devices restricting the flow. A fairly thorough evaluation study of the numerical met
Scholars have argued that the end of the Cold War and the War on Terror have radically changed the context of war and defense, diminished the role of nation-states in favor of multi-lateral defense activities, and placed a new focus on human security. International peacekeeping has superseded the traditional act of war-making as the most important defense strategy among wealthy, liberal-democratic
