Ventilated rainscreen cladding: A study of the ventilation drying process

The air exchange in rainscreen walls is expected to provide ventilation drying if excess moisture is absorbed in the wall construction. In an earlier paper, we presented a cavity airflow model and measurement based estimations of air change rates (ACH) in south-facing experimental walls. Here, focus is on the ventilation drying process and its practical implications. ACH in the experimental walls

Simultaneous heat and moisture transport in porous building materials: evaluation of nonisothermal moisture transport properties

The paper presents a mathematical model for calculating the nonisothermal moisture transfer in porous building materials. The simultaneous heat and moisture transfer problem was modeled. Vapor content and temperature were chosen as principal driving potentials. The coupled equations were solved by a numerical method. An experimental methodology for determining the temperature gradient coefficient

Variation in host specificity and gene content in strains from genetically isolated lineages of the ectomycorrhizal fungus Paxillus involutus s. lat.

Ectomycorrhizal fungi are known to vary in host range. Some fungi can enter into symbiosis with multiple plant species, while others have restricted host ranges. The aim of this study was to examine variation in host specificity among strains from the basidiomycete Paxillus involutus s. lat. Recent studies have shown that this fungus consists of at least four genetically isolated lineages, phyloge

Tassiloa, a new genus in the Teloschistaceae (lichenized ascomycetes)

The new genus Tassiloa, proposed for the American Caloplaca digitaurea-group, is supported by phylogenetic analyses based on ITS and LSU nrDNA-sequences, and 12S SSU mtDNA-sequences. The genus is positioned in the Catenarina-clade in the subfamily Teloschistoideae of the family Teloschistaceae. The genus Tassiloa is described and compared with closely related genera. Two new combinations are propo

Faster data structures and graphics hardware techniques for high performance rendering

Computer generated imagery is used in a wide range of disciplines, each with different requirements. As an example, real-time applications such as computer games have completely different restrictions and demands than offline rendering of feature films. A game has to render quickly using only limited resources, yet present visually adequate images. Film and visual effects rendering may not have st

Myeloid translocation gene-16 co-repressor promotes degradation of hypoxia-inducible factor 1.

The myeloid translocation gene 16 (MTG16) co-repressor down regulates expression of multiple glycolytic genes, which are targets of the hypoxia-inducible factor 1 (HIF1) heterodimer transcription factor that is composed of oxygen-regulated labile HIF1α and stable HIF1β subunits. For this reason, we investigated whether MTG16 might regulate HIF1 negatively contributing to inhibition of glycolysis a

Neutron reflectometry on highly absorbing films and its application to (B4C)-B-10-based neutron detectors

Neutron reflectometry is a powerful tool used for studies of surfaces and interfaces. The absorption in the typical studied materials is neglected and this technique is limited only to the reflectivity measurement. For strongly absorbing nuclei, the absorption can be directly measured by using the neutron-induced fluorescence technique which exploits the prompt particle emission of absorbing isoto

Disputes and Going Concerns in an Institution for "Troublesome" Boys

Everett C. Hughes's classic concept of a "going concern" should stand for both entire institutions and for chains of activities within institutions. In this article the author explores this expanded version of Hughes's concept to show how staff and residents in a youth care setting interweave everyday concerns-meals, lessons, breaks, meetings, or other mundane but concerted projects-with interpers

Search for doubly charged Higgs bosons in like-sign dilepton final states at root s=7 TeV with the ATLAS detector

A search for doubly charged Higgs bosons decaying to pairs of electrons and/or muons is presented. The search is performed using a data sample corresponding to an integrated luminosity of 4.7 fb(-1) of pp collisions at root s = 7 TeV collected by the ATLAS detector at the LHC. Pairs of prompt, isolated, high-p(T) leptons with the same electric charge (e(+/-)e(+/-), e(+/-)mu, mu(+/-)mu(+/-)) are se

On the edge of death: Rates of decline and lower thresholds of biochemical condition in food-deprived fish larvae and juveniles

Gaining reliable estimates of how long fish early life stages can survive without feeding and how starvation rate and time until death are influenced by body size, temperature and species is critical to understanding processes controlling mortality in the sea. The present study is an across-species analysis of starvation-induced changes in biochemical condition in early life stages of nine marine

Progress in treatment and risk stratification of neuroblastoma: Impact on future clinical and basic research.

Close international collaboration between pediatric oncologists has led to marked improvements in the cure of patients, seen as a long-term overall survival rate of about 80%. Despite this progress, neuroblastoma remains a challenging disease for both clinicians and researchers. Major clinical problems include lack of acceptable cure rates in high-risk neuroblastoma and potential overtreatment of

Activity-based assessment (BIA) - inter-rater reliability and staff experiences

The BIA method, based on assessment of patients in activities, was developed to enable reliable assessment of clients' occupational functioning. The method evaluates the patient's ego functions and capacity for activity and participation. The aims of this study were to examine inter-rater reliability for the BIA method and to compare the experiences of staff working with the BIA with those of staf

Binding of Semenogelin I to Intact Human Spermatozoa Studied by Flow Cytometry and Surface Plasmon Resonance

Approximately 1 in 10 couples is infertile No definite cause can be found in about 25% of those cases Studies have indicated that seminal vesicle secretion functions as an optimizer of fertilization The Zn2+ binding protein semenogelin I (SgI) represents a major fraction of the proteins present in seminal vesicle fluid and it serves as a structural component of the coagulum that is formed after ej

Dubbelt upp om Wallenberg

Visualizing overdamped wavepacket motion: Excited-state isomerization of pseudocyanine in viscous solvents

The isomerization of 1,1'-diethyl-2,2'-cyanine iodide in n-alcohols is studied by femtosecond pump-probe spectroscopy. Using a broad range of probe wavelengths, the dynamics of ground-state bleach recovery, excited-state absorption and stimulation emission are monitored. We attributed the observed spectral evolution to the excited-state torsional motion, which occurs in a barrierless fashion in al

Intelligensaristokrater och arkivmartyrer : normerna för vetenskaplig skicklighet i svensk historieforskning 1900–1945

The dissertation deals with the construction of norms of academic excellence in the Swedish discipline of history 1900-1945. The area of focus is the competition for professorial chairs in history. The legacy of the discipline viewed history as a holistic concept, binding together most humanistic disciplines. From the perspective of this legacy, the view of empirical specialization was becoming in
