On several occasions during my many years of working with various snake species, I observed a significant positive relationship between body condition and head size (the former calculated from residual scores from a general linear regression of In-transformed mass on In-transformed snout-vent length). Based on results from my long-term study of water pythons (basis fuscus) this relationship is, ho
Transition problems from secondary to tertiary level in mathematics have been a recurrent issue in Sweden. This paper summarises the development during the last decades. Results from two recent research studies that illuminate the transition problem are presented. The first one, based on empirical data from a major Swedish technical university, characterises the widening gap, in content and in app
Despite the vast amount of studies focusing on bone nanostructure that have been performed for several decades, doubts regarding the detailed structure of the constituting hydroxyapatite crystal still exist. Different experimental techniques report somewhat different sizes and locations, possibly due to different requirements for the sample preparation. In this study, small- and wide-angle X-ray s
We compiled literature, intensively studied 15 sites as a group, and collected opportunistically in other areas of the Yosemite National Park. We report a total of 562 species of lichenized fungi from the Park, adding 461 species to the total of 101 species reported for the Park by the National Park Service database. An additional 22 lichenicolous fungi are reported here. Two nonlichenized fungi a
Popular Abstract in Danish Børn og især piger med spændingshovedpine (på engelsk tension-type headache,TTH) har en høj forekomst på verdensplan og betyder for børnene en risiko for skolefravær, medicin over forbrug og vedvarende hovedpine. Den viden, der findes om fysiske faktorers sammenhæng med hovedpine, er begrænset, ligesom viden og dokumentation for interventioner er det. Det overordnede målTension-type headache (TTH) in children and especially girls is a prevalent problem worldwide, and means there is a risk of school absenteeism, medication overuse and persistent headache. Knowledge about the associated physical factors is limited, as is knowledge on evidence based interventions. The overall aim of this thesis was to examine the associations of physical factors with frequent or chr
Background-beta-Adrenergic stimulation is the main trigger for cardiac events in type 1 long-QT syndrome (LQT1). We evaluated a possible association between ion channel response to beta-adrenergic stimulation and clinical response to beta-blocker therapy according to mutation location. Methods and Results-The study sample comprised 860 patients with genetically confirmed mutations in the KCNQ1 cha
This report documents the program and the outcomes of Dagstuhl Seminar 13331 "Exponential Algorithms: Algorithms and Complexity Beyond Polynomial Time". Problems are often solved in practice by algorithms with worst-case exponential time complexity. It is of interest to find the fastest algorithms for a given problem, be it polynomial, exponential, or something in between. The focus of the Seminar
The present investigation focus on the receptor Axl, which is a member of the receptor tyrosine kinase family. Axl is activated by the ligand Gas6 inducing cell growth and proliferation, but also regulate inflammation and vascular homeostasis. The Axl receptor can be cleaved outside the membrane, releasing the extracellular, soluble domain, which alone can bind Gas6, removing it from cellbound rec
This article investigates by means of US Patent and Trademark Office (USPTO) patent data whether technological relatedness at the city level was a crucial driving force behind technological change in 366 US cities from 1981 to 2010. Based on a three-way fixed-effects model, we find that the entry probability of a new technology in a city increases by 30% if the level of relatedness with existing t
As with mosquitoes, female tabanid flies search for mammalian hosts by visual and olfactory cues, because they require a blood meal before being able to produce and lay eggs. Polarotactic tabanid flies find striped or spotted patterns with intensity and/or polarisation modulation visually less attractive than homogeneous white, brown or black targets. Thus, this reduced optical attractiveness to t
We present the results of the measurements of the detection efficiency for a 4.7 angstrom neutron beam incident upon a detector incorporating a stack of up to five MultiWire Proportional Counters (MWPC) with Boron-coated cathodes. The cathodes were made of Aluminum and had a surface exhibiting millimeter-deep V-shaped grooves of 45 degrees, upon which the thin Boron film was deposited by DC magnet
Popular Abstract in Swedish Diabetes, i dagligt tal även kallat sockersjuka, kännetecknas av konstant förhöjt blodsocker. Sjukdomen ökar lavinartat, och har beskrivits som en av det moderna samhällets stora epidemier. Diabetes förekommer i två huvudsakliga former, typ 1 och typ 2. I typ 1-diabetes, som framför allt drabbar barn och ungdomar, har de insulinproducerande beta-cellerna förstörts av krDefective insulin secretion from the pancreatic B-cells is a central feature in type 2 diabetes (T2D). There is a strong hereditary component in type T2D, but the underlying pathophysiology remains largely unknown. This thesis uses a combination of gene network analysis and cell-physiological techniques to explore the genetic and cellular basis for impaired insulin secretion in T2D. We found that
Fläderskära är en nordamerikansk art som spritt sig till de tempererade delarna av Europa. Introduktionen till Blekinge är intressant, eftersom arten följde med importerad vass från Tyskland, som skulle användas som en s.k. kvävefälla till Kallinge flygplats utanför Ronneby. Fläderskäran förekommer här i ett rikt bestånd och kanske den etablerar sig.
Substance use disorders are regarded as one of the most prevalent, deadly and costly of health problems. Research has consistently found that the prevalence of other psychiatric disorders among those with substance related disorders is substantial. Combined, these disorders lead to considerable disability and health years lost worldwide as well as extraordinary societal costs. Relatively little of
