Remote monitoring and logging of relative humidity in concrete

It is important to measure the relative humidity, RH, level in a concrete slab before applying semi permeable flooring to the surface. If the moisture level in the concrete is too high when the flooring is applied the high alkali level in combination with the moisture will degrade the adhesive. This paper describes a new system used to continuously measure and monitor RH in situ during the constru

Ovarian cancer and oral contraceptives: collaborative reanalysis of data from 45 epidemiological studies including 23 257 women with ovarian cancer and 87 303 controls

Background Oral contraceptives were introduced almost 50 years ago, and over 100 million women currently use them. Oral contraceptives can reduce the risk of ovarian cancer, but the eventual public-health effects of this reduction will depend on how long the protection lasts after use ceases. We aimed to assess these effects. Methods Individual data for 23 257 women with ovarian cancer (cases) a

Proposal and evaluation for organising and using available data for software performance estimations in embedded platform development

Embedded platform development, where a platform is a basis for a family of products, is characterized by soft-and hardware co-design as well as very tight constraints on cost and available real-time system performance. The latter implies that early software performance estimation plays a crucial role in embedded platform development. Due to the different focus of software and hardware design, perf

Etniskt företagande som startmotor: Erfarenheter från somaliska företagare i USA

Det är tio gånger så vanligt att migranter från Somalia startar eget företag i Minnesota, som i Sverige. Sysselsättningsgraden för somaliafödda är också två till tre gånger högre i USA. I rapporten ”Etniskt företagande som startmotor” har ekonomhistorikerna Benny Carlson och Tobias Schölin vid Lunds universitet intervjuat företagare och företrädare för somaliska företagarcenter i Minnesota.

Proper functioning of domestic hot water circulation in residential buildings

The paper deals with domestic hot water circulation (DHWC) in residential buildings. Thermostatic circulation valves (TCV) of self-acting type can be used to assure proper temperature level in DHWC systems. A mathematic model of a DHWC system with TCV's in a 36 flat residential building is presented as well as results from steady-state and dynamic Simulations. The TCV design values used in simulat

Uncertain Futures : Adaptive capacities to climate variability and change in the Lake Victoria Basin

The Lake Victoria basin (LVB) in East Africa can be considered a climate change hotspot because of its large rural population dependent on rain-fed farming. Drawing on extensive fieldwork (2007-2011) in rural communities along the shores of Lake Victoria in Kenya and Tanzania, I explore adaptive capacities to climate variability and change and discuss how they interrelate in situ. Using multiple m

The corticolous and lignicolous species of Bacidia and Bacidina in North America

This is a taxonomic revision of the corticolous and lignicolous taxa of the genera Bacidia and Bacidina (Lecanoraceae, Lecanorales, lichenized Ascomycotina) in the continental United States and Canada. Twenty-seven species of Bacidia (one of which is divided into two subspecies) and twelve species of Bacidina are recognized. The morphology, secondary chemistry, ecology, and phytogeography of these

Pedagogical courses as a way to support communities of practice focusing on teaching and learning

This paper argues for the idea that pedagogical courses for university teachers should be designed with a socio cultural perspective on learning in mind. It also presents an example of such a design. Teaching and learning regimes are ways to understand crucial aspects of teaching within e.g. departments. They are constructed within communities of practice where colleagues use whatever resources t

Evidence base treatments for childhood PTSD

Abstract in UndeterminedPosttraumatic Stress Disorder (PTSD) is the one of the most common reactions arising in the aftermath of traumatic events. PTSD is characterised by frequent and intrusive recollections of the event, emotional restriction and avoidance, and hyper arousal. Many clients also develop dysfunctional beliefs about their own PTSD symptoms, which in turn cause increased levels of im

Textens tilltal: Konsten att bilda meningar

The book consists of nine chapters which address three major topics: current issues in biblical scholarship, various aspects of love and death, and also theology of religions. It is a sequel to the previous book "Skriftens ansikten: Konsten att läsa mellan raderna".

Mathematical modelling of metric-driven routing and resource allocation in wireless mesh networks

The traditional routing protocols used in wireless mesh networks like AODV are not very efficient since the number of hops to a destination is mainly considered as the routing metric. This may lead to shorter paths; however, the throughput can decrease when traffic is routed through those paths. Various contributions have proposed different metrics or completely different routing algorithms. Never

Anorexia nervosa in 51 Swedish adolescents: premorbid problems and comorbidity

Fifty-one teenage cases with anorexia nervosa (AN) were compared with 51 age-, sex-, and school-matched cases with respect to premorbid developmental, physical, and psychiatric problems and comorbidity at the time of examination. Almost half of the AN group consisted of the total population of AN cases in one birth cohort. There were more premorbid personality problems in the AN group. Obsessive c

Nuclear motion in molecular ions studied with synchrotron radiation and multicoincidence momentum imaging spectrometry

Popular Abstract in Swedish Förståelse av väldigt snabba proceeser i molekyler utgör grunden inom modern kemi. Jonisation och excitation av en molekyl med en foton startar en nukleär dynamisk process som åtföljs av elektroniskt sönderfall och fragmentering av molekylen. En rörelsemändsvektor-spektrometer har utveclats som används för att mäta massa, laddning, energi och hastighet av joniska fragmeA momentum imaging spectrometer optimized for photoionization experiments with synchrotron radiation was built in 2008. The spectrometer is equipped with an electrostatic lens, that focuses the charged dissociation products on to a position-sensitive multi-hit delay line anode. The possibility of focusing is essential for most applications, where fragment momentum is to be extracted. The apparatus
