Moisture safety in wood frame walls : blind evaluation of the hygrothermal calculation tool WUFI 5.0 using field measurements and determination of factors affecting the moisture safety

Due to increased awareness of climate change and higher energy costs, well‐insulated buildings have become more common. Furthermore, the interests of using wood in building to produce more carbon dioxide‐efficient houses have increased. However, thicker thermal insulation in walls increases the risk of high relative humidity levels and the risk of mould‐related damage in Wood frame houses. In orde

Danska spår i syd- och västsvenskt kyrkoliv - kan LUKA ge svar?

Traces of Danish-Norwegian Church life in South and Western Sweden did not disappear after 1658. Rather the nineteenth and twentieth century changes of Church structure and services weakened or dispersed of the Danish traces. But then they were not any more interpreted as Danish. The ongoing, frequent amalgamation of parishes means a final break with the original, Danish Church structure in the co

Highly Accurate Excited-State Structure of [Os(bpy)(2)dcbpy](2+) Determined by X-ray Transient Absorption Spectroscopy

Determining the electronic and geometric structures of photoexcited transient species with high accuracy is crucial for understanding their fundamental photochemistry and controlling their photoreactivity. We have applied X-ray transient absorption spectroscopy to measure the XANES and EXAFS spectra of a dilute (submillimolar) solution of the osmium(II) polypyridyl complex [Os(bpy)(2)dcbpy](PF6)(2

Study of Isomer Production Rates for A=142-152 and Z=62-67 in Fragmentation of a Relativistic 208Pb Beam

We have investigated nuclear fragmentation reactions of a relativistic Pb-208 beam. Ten isomeric states for nuclei with A = 142-152 and Z = 62-67 were observed. Measured isomeric ratios were compared, together with values from other experiments, with prediction of theoretical models. The discrepancies between the experimental and theoretical values were discussed in terms of transitions by-passing

God’s Plan in Job and the “Wise Things” of Marduk

The article relates the concept of God's "plan" in Job 38:2 and 42:3 to similar concepts in earlier Ancient Near Eastern mythological literature, especially the term niklātu ("wise, ingenious things") used in the Babylonian Enuma Elish to describe the actions of Marduk - both the battle against the chaos monster Tiamat and the creation of the earthly world. Parallels are also drawn to expressions

A 3-D study of mineral inclusions in chromite from ordinary chondrites using synchrotron radiation X-ray tomographic microscopy-Method and applications

A method is described for imaging in 3-D the interiors of meteoritic chromite grains and their inclusions using synchrotron radiation X-ray tomographic microscopy. In ordinary chondrites, chromite is the only common mineral that survives long-term weathering on Earth. Information about the silicate matrix of the original meteorite, however, can be derived from mineral inclusions preserved in the p

Multisystemisk terapi i Sverige : Evidensbaserad metod i nytt sammanhang

This dissertation deals with the transferability of an evidence-based treatment method from one cultural context to another, with Multisystemic Therapy (MST) in Sweden as an example. The primary research question is whether the evidence-based treatment intervention MST can be transferred from the US to Sweden with retained treatment effects. This thesis is organized around four separate but interr

First experimental implementation of pulse shaping for neutron diffraction on pulsed sources

One of the central issues in the design and the use of pulsed neutron sources is the control of pulse length in elastic scattering experiments, most significantly diffraction on crystalline matter. On the existing short pulse spallation sources the strongly wavelength dependent source pulse length that determines the resolution is permanently fixed on each beam line by the type of the moderator it

Electron and Hole Contributions to the Terahertz Photoconductivity of a Conjugated Polymer:Fullerene Blend Identified

Time-resolved terahertz spectroscopy was employed for the investigation of charge-transport dynamics in benzothiadiazolo-dithiophene polyfluorene ([2,7-(9,9-dioctylfluorene)-alt-S,S-(4',7'-di-2-thieny1-2',1',3'-benzothiadiazole)]) (APFO-3) polymers with various chain lengths and in its monomer form, all blended with an electron acceptor ([6,6]-phenyl-C61-butyric acid methyl ester, PCBM). Upon phot

Hydration and Mobility of Trehalose in Aqueous Solution.

The disaccharide trehalose stabilizes proteins against unfolding, but the underlying mechanism is not well understood. Because trehalose is preferentially excluded from the protein surface, it is of interest to examine how trehalose modifies the structure and dynamics of the solvent. From the spin relaxation rates of deuterated trehalose and (17)O-enriched water, we obtain the rotational dynamics

Modellering av klimatets påverkan på produktion och risk för skadegörare inom jordbruket.

I den här kunskapssammanställningen tar vi upp frågor som rör hur ett förändrat klimat kan komma att påverka tillväxt och skörd av olika jordbruksgrödor, samt hur klimatet kan påverka risken för angrepp av nya och redan etablerade skadegörare och växtsjukdomar i Sverige. Ökad temperatur leder till förlängning av växtsäsongen och utrymme för produktionsökning. I takt med att klimatet blir varmare k

Diffusion in evaporating solutions

We present an analysis of the colloidal dynamics of particles in a mixture of two solvents subjected to evaporation. For simplicity, only one out of the two solvents is considered to be volatile. The evaporation generates a distribution of the solvent concentration in the system. As the particles selectively interact with the solvents, their migration becomes affected by a "chemotaxis" force, caus

In hot pursuit: fluctuating mating system and sexual selection in sand lizards

A changing climate is expected to have profound effects on many aspects of ectotherm biology. We report on a decade-long study of free-ranging sand lizards (Lacerta agilis), exposed to an increasing mean mating season temperature and with known operational sex ratios. We assessed year-to-year variation in sexual selection on body size and postcopulatory sperm competition and cryptic female choice.

Multi-component self-assembly of molecule based materials by coordination networks and weak intermolecular synthons

The coordination polymer [Fe(SCN)(2)(1,2-bis(4-pyridylmethylene)hydrazine)(2)](n) [Fe(phenanthroline)(3)](2n)(ClO4)(2n)center dot n1,2-bis(4-pyridylmethylene)hydrazine center dot 4nH(2)O 1 was crystallised from a MeOH/MeCN solution and the structure consists of layered (4,4) 2D-nets with supramolecular ([Fe(phen)(3)](2)bphz)(4+) units in the pores and disordered water and perchlorate anions. The s

First evidence of Devonian strata in Sweden - A palynological investigation of Ovedskloster drillcores 1 and 2, Skane, Sweden

Palynological analyses were carried out on 50 samples from the Ovedskloster 1 (O1) and 2 drillcores (O2), southern Sweden. The study revealed well-preserved palynological assemblages including 77 spore species in 28 genera, and some additional forms retained under open nomenclature. The spore assemblages are collectively dominated by trilete spores in terms of abundance and diversity and have been
