Urban, pluvial flooding : Blue-green infrastructure as a strategy for resilience

I denna avhandling studeras urbana, pluviala översvämningar och om blågrön infrastruktur, för hantering av dagvatten i urbana grönområden, kan användas som en strategi för motståndskraftig hantering av översvämningsrisk. Spatial analys av översvämningsskador från försäkringsbolag och Malmös VA-huvudman, VA SYD, används för att bättre förstå de hur olika mekanismer och egenskaper i stadens rörnät, This thesis investigates urban, pluvial flooding and if blue-green infrastructure, for handling of stormwater in urban green spaces, can be used as a strategy for resilient flood risk management. Spatial analyses of flood claims from insurance companies and the water utility company of Malmö are used to better understand the mechanisms and characteristics of pluvial flooding and how blue-green inf

Effect of high voltage pulses on survival of Chinese hamster V79 lung fibroblast cells

The objective is to study the effect of high voltage pulses on living cells to find the most effective combination of physical parameters to be used in tumour therapy. Four parameters that affect the cell survival are the pulse shape, electric field strength, pulse length and the number of pulses and their cell killing effect were investigated in this work. High voltage square wave or exponentiall

Cooperation facilitates the colonization of harsh environments

Animals living in harsh environments, where temperatures are hot and rainfall is unpredictable, are more likely to breed in cooperative groups. As a result, harsh environmental conditions have been accepted as a key factor explaining the evolution of cooperation. However, this is based on evidence that has not investigated the order of evolutionary events, so the inferred causality could be incorr

Comparative Study on the Machinability and Manufacturing Cost in Low-Lead Brass

Today, commercially used brasses commonly contain 2 to 4 wt.% lead. As the availability of low-lead and lead-freebrass increase, there are environmental incentives for investigating the consequences of replacing thelead-containing brasses with lead-free equivalents. Generally, lead-free brass is expected to have a lowermachinability than its lead-alloyed counterpart, implying a higher manufacturin

The Roles of the Olivocerebellar Pathway in Motor Learning and Motor Control. A Consensus Paper

For many decades, the predominant view in the cerebellar field has been that the olivocerebellar system’s primary function is to induce plasticity in the cerebellar cortex, specifically, at the parallel fiber-Purkinje cell synapse. However, it has also long been proposed that the olivocerebellar system participates directly in motor control by helping to shape ongoing motor commands being issued b

Reduction of the nitrate content in baby spinach leaves by vacuum impregnation with sucrose

Vacuum impregnation (VI) has been widely utilized as a pre-treatment method prior to, e.g., the minimal processing, freezing, or drying of foods. In many cases, VI has been used to focus on the enrichment of fruits and vegetables with probiotics or micronutrients, texture enhancement, the modification of the sensory attributes, and extension of shelf life by pH reduction. However, little attention

Ongoing Pharmacological Management of Chronic Pain in Pregnancy

The article discusses possible effects of the use of analgesics during pregnancy. It summarizes the pertinent literature and reports some previously unpublished data from the Swedish Medical Birth Register. Most likely the use of analgesics does not cause spontaneous abortion. Only small malformation risk increases are seen after the use of opioids and perhaps non-steroid anti-inflammatory drug (N

Rotational coherent anti-Stokes Raman spectroscopy (CARS) in nitrogen at high pressures (0.1-44 MPa) : Experimental and modelling results

Pure rotational coherent anti-Stokes Raman scattering (CARS) has for the first time been investigated for pressures up to 44 MPa in nitrogen gas at room temperature. An atomic filter consisting of a heated cell with sodium vapour was successfully applied for suppression of stray light originating from the narrowband CARS pump laser beam. With increasing pressure the rotational CARS spectrum is smo

The mediatization of diplomacy

Practitioners and scholars are increasingly aware that an array of new actors, communication technologies, agendas and expectations are changing the institution of diplomacy. How diplomatic actors are known and experienced through their representation assumes an increasingly important, and uncertain, role. This article argues that these changes to the field should be considered in terms of the shi

The Growth of External Ectomycorrhizal Mycelia in the Field in Relation to Host Nutrient Status and Local Addition of Mineral Sources

Popular Abstract in Swedish I stort sett alla finrötter hos gran och många andra trädslag är koloniserade av ektomykorrhizasvampar (EM-svampar). Dessa lever i symbios med granen och utbyter mineralnäringsämnen mot sockerarter, som värdträdet bildat i fotosyntesen. EM-svamparna har visats överföra kalcium, kalium, kväve, magnesium och fosfor till sina värdträd. Den svenska skogen ingår i det boreaA method based on ingrowth mesh bags was developed to study the production of EMM. These bags were made of nylon mesh with a mesh size of 50 mu-m, which allows colonisation by fungal mycelia but excludes the tree roots. Using this method, the production of EMM was estimated in forest stands subjected to whole-tree harvesting (WTH) and in forest stands with different nutrient status regarding potas

Study on Combustion Chamber Geometry Effects in an HCCI Engine using High-Speed Cycle-Resolved Chemiluminescence Imaging

The aim of this study is to see how geometry generated turbulence affects the Rate of Heat Release (ROHR) in an HCCI engine. HCCI combustion is limited in load due to high peak pressures and too fast combustion. If the speed of combustion can be decreased the load range can be extended. Therefore two different combustion chamber geometries were investigated, one with a disc shape and one with a sq

Encapsulated zinc salt increases the diffusion of protein through PLG films.

The use of microspheres and nanospheres of poly(d,l-lactide-co-glycolide) (PLG) as a controlled-release drug delivery system has been the subject of great interest for at least two decades within the field of pharmaceuticals. Salts of zinc and other divalent cations are sometimes co-encapsulated in PLG particles to control the pH or to stabilize encapsulated proteins or peptides. Zinc salts are kn

Interaction between colloids with grafted diblock polyampholytes

The interaction between composite colloidal particles composed of a spherical core and grafted AB-diblock polyampholytes (diblock copolymers with oppositely charged blocks) are investigated by using a coarse-grained model solved with Monte Carlo simulations. The B block is end-grafted onto the core of the colloid and its linear charge density is varied, whereas the linear charge density of the A b

Preoperative rectal diclofenac versus paracetamol for tonsillectomy: effects on pain and blood loss

BACKGROUND: Diclofenac is widely used for postoperative analgesia but the perioperative safety of this drug is controversial because of its effect on platelet aggregation, which might increase blood loss. In a prospective investigator-blinded study the effects of diclofenac and paracetamol on pain and blood loss were compared in patients undergoing tonsillectomy. METHOD: Ninety patients were rando

Vesicle formation and other structures in aqueous dispersios of monoolein and sodium oleate

The macroscopic appearance and microstructure in the dilute corner of the ternary monoolein (MO)-sodium oleate (NaO)-water ((H2O)-H-2) system have been investigated by visual inspection and by using direct structural imaging with light microscopy and cryogenic transmission electron microscopy. The microstructural transformations that take place between the micellar phase (binary NaO-(H2O)-H-2 axis

Decrease in intramuscular lipid droplets and translocation of HSL in response to muscle contraction and epinephrine

A better understanding of skeletal muscle lipid metabolism is needed to identify the molecular mechanisms relating intramuscular triglyceride (IMTG) to muscle metabolism and insulin sensitivity. An increasing number of proteins have been reported to be associated with intracellular triglyceride (TG), among them the PAT family members: perilipin, ADRP ( for adipocyte differentiation-related protein
