Homelessness as a political and social dominion has a number of features that make it particularly difficult to tackle. In addition to being a wicked problem, homelessness offers several analytical avenues. How do these characteristics affect the evaluation of programmes and projects aspiring to combat homelessness? Dissimilar pictures and solutions regarding homelessness in the US and in European

Part of the justification for an integrated view of speech and gestures ( (( is their temporal coordination. Gestures generally coincide with or precede, but rarely follow lexical affiliate (McNeill, 1992). How synchrony impacts listeners remains less explored, despite potential relevance for video communication and virtual conversational agents. ERP studies suggest that temporal alignment affects

Background: Environmental lead exposure is a possible causative factor for increased blood pressure and hypertension, but large studies at low-level exposure are scarce, and results inconsistent. Objective: We aimed to examine the effects of environmental exposure to lead in a large population-based sample. Methods: We assessed associations between blood lead and systolic/diastolic blood pressure

Traditional chromatographic methods for the analysis of lignin-derived phenolic compounds in environmental samples are generally time consuming. In this work, an ultra-high performance supercritical fluid chromatography method with a diode array detector for the analysis of major lignin-derived phenolic compounds produced by alkaline cupric oxide oxidation was developed. In an analysis of a collec

We demonstrate crack-free ZnO/GaN distributed Bragg reflectors (DBRs) grown by hybrid plasma-assisted molecular beam epitaxy using the same growth chamber for continuous growth of both ZnO and GaN without exposure to air. This is the first time these ZnO/GaN DBRs have been demonstrated. The Bragg reflectors consisted up to 20 periods as shown with cross-sectional transmission electron microscopy.

On-line supported liquid membrane (SLM) extraction and microporous membrane liquid-liquid extraction (MMLLE) techniques for sample preparation of natural water samples have been developed for the determination of thiophanate-methyl (TM), carbendazim (MBC) and 2-aminobenzimidazole (2-AB) using reversed-phase HPLC. The combination of SLM extraction and MMLLE offers extraction conditions that makes i

An automated system with microporous membrane liquid-liquid extraction (MMLLE) combined with HPLC has been designed for the determination of Vinclozolin in aqueous matrices. In MMLLE a porous hydrophobic membrane separates an aqueous phase from an organic phase. The pores are filled with the organic solvent. In this work, MMLLE was performed in a flow system and coupled on-line to normal phase HPL

The decline of the two fungicides vinclozolin (formulation Ronilan FL) and triadimefon (formulation Bayleton Special) was studied in greenhouses. The decline of vinclozolin was also studied in climate chambers. In greenhouse experiments the fungicides were applied with either a low-volume sprayer or a high-volume sprayer, while in the climate chamber experiments the fungicide was applied with a pi

A new analysis procedure for fungicides has been developed gearing toward estimation of worker exposure in greenhouses. The procedure includes sampling on leaves, glass, and polymers using vinclozolin and triadimefon as model substances and starts with solvation of the fungicides with ethanol from the surface. It proceeds by collection of the solution on disks of cloth, disk extraction with excess

The supported liquid membrane technique offers new possibilities for analytical enrichment, field sampling and speciation. The possibility of using the technique for the enrichment of metals in a flow system with off-line atomic absorption spectrometry in the final analysis step is outlined. Five metals (Cu, Cd, Co, Ni and Zn) have been used as model substances and different approaches to transpor

Biografisk skildring av den tyske äventyraren Theodor von Neuhoff (1684?-1756), kortvarig kung av Korsika, samt utredande av påståendet att denne skulle ha varit student i Lund.

The latitudinal diversity gradient predicts higher species richness at lower latitudes. Here, we utilize the data from a long-term monitoring with malaise traps to analyse if spider communities in Sweden are affected by geographic gradients and if these effects hold independent of forest type. The species richness and the effective number of species in spider communities were not significantly rel

The reconstruction of midbrain dopamine (DA) circuitry through intracerebral transplantation of new DA neurons contained in embryonic ventral mesencephalon (VM) is a promising therapeutic approach for Parkinson's disease (PD). Although some of the early open-label trials have provided proof-of-principal that VM grafts can provide sustained improvement of motor function in some patients, subsequent

BACKGROUND: Injury to the white matter may lead to impaired neuronal signaling and is commonly observed following traumatic brain injury (TBI). Although endogenous repair of TBI-induced white matter pathology is limited, oligodendrocyte progenitor cells (OPCs) may be stimulated to proliferate and regenerate functionally myelinating oligodendrocytes. Even though OPCs are present throughout the adul

Clinical outcome after traumatic diffuse axonal injury (DAI) is difficult to predict. In this study, three magnetic resonance imaging (MRI) sequences were used to quantify the anatomical distribution of lesions, to grade DAI according to the Adams grading system, and to evaluate the value of lesion localization in combination with clinical prognostic factors to improve outcome prediction. Thirty p

Widespread traumatic axonal injury (TAI) results in brain network dysfunction, which commonly leads to persisting cognitive and behavioural impairments following traumatic brain injury (TBI). TBI induces a complex neuroinflammatory response, frequently located at sites of axonal pathology. The role of the pro-inflammatory cytokine interleukin (IL)-1β has not been established in TAI. An IL-1β-neutr

OBJECTIVE: Traumatic brain injury is a major global public health problem for which specific therapeutic interventions are lacking. There is, therefore, a pressing need to identify innovative pathomechanism-based effective therapies for this condition. Thrombus formation in the cerebral microcirculation has been proposed to contribute to secondary brain damage by causing pericontusional ischemia,

A large variety of rodent behavioral tests are currently being used to evaluate traits such as sensory-motor function, social interactions, anxiety-like and depressive-like behavior, substance dependence and various forms of cognitive function. Most behavioral tests have an inherent complexity, and their use requires consideration of several aspects such as the source of motivation in the test, th
