Within-population variation in ejaculate characteristics in a prolonged breeder, Peron's tree frog, Litoria peronii

Sperm number is often a good predictor of success in sperm competition; however, it has become increasingly clear that, for some species, variation in probability of paternity cannot be explained by sperm number alone. Intraspecific variation in ejaculate characteristics, such as the number of viable sperm and sperm longevity, may play an equally important role in determining fertilization success

Interobserver and intraobserver agreement in the evaluation of CT perfusion in ischemic stroke

Knowledge of interrater reliability in the evaluation of perfusion computed tomography (CTP) studies is very limited even though the method is widely used in the workup of acute stroke. The aims of this study were to estimate the inter- and intraolbserver agreement in the evaluation of CTP data and to evaluate the feasibility of the method. The CTP data of 20 consecutive patients (50% were females

Modeling dengue outbreaks

We introduce a dengue model (SEIR) where the human individuals are treated on an individual basis (IBM) while the mosquito population, produced by an independent model, is treated by compartments (SEI). We study the spread of epidemics by the sole action of the mosquito. Exponential, deterministic and experimental distributions for the (human) exposed period are considered in two weather scenarios

Frequent detection of respiratory agents by multiplex PCR on oropharyngeal samples in Swedish school-attending adolescents

Background: Respiratory agents may be detected in the oropharynx of healthy individuals. The extent of this condition and the reasons behind it are largely unknown. The objective of this study was to determine the factors associated with the presence of respiratory agents in the oropharynx of adolescents healthy enough to attend school activities. Methods: On a single day in December, samples from

Wetland development, permafrost history and nutrient cycling inferred from late Holocene peat and lake sediment records in subarctic Sweden

Permafrost in peatlands of subarctic Sweden is presently thawing at accelerated rates, which raises questions about the destiny of stored carbon and nutrients and impacts on adjacent freshwater ecosystems. In this study we use peat and lake sediment records from the Stordalen palsa mire in northern Sweden to address the late Holocene (5,000 cal BP-present) development of the mire as well as relate

Self-reported emotional and behavioral problems in Swedish 14 to 15-year-old adolescents: A study with the self-report version of the Strengths and Difficulties Questionnaire.

The psychometric properties of the Swedish self-report version of the Strengths and Difficulties Questionnaire (SDQ-s), and the prevalence of emotional and behavioral problems as measured by the SDQ-s, were studied in 14 to 15-year-old adolescents. The psychometric properties were found to be similar to those found in other language versions, in terms of similar factor structure and acceptable tes

A BRCA2 mutation incorrectly mapped in the original BRCA2 reference sequence, is a common West Danish founder mutation disrupting mRNA splicing

Inherited mutations in the tumor suppressor genes BRCA1 and BRCA2 predispose carriers to breast and ovarian cancer. The authors have identified a mutation in BRCA2, 7845+1G > A (c.7617+1G > A), not previously regarded as deleterious because of incorrect mapping of the splice junction in the originally published genomic reference sequence. This reference sequence is generally used in many laborator

Current trends in stroke rehabilitation. A review with focus on brain plasticity.

Johansson BB. Current trends in stroke rehabilitation. A review with focus on brain plasticity. Acta Neurol Scand: DOI: 10.1111/j.1600-0404.2010.01417.x. (c) 2010 John Wiley & Sons A/S. Current understanding of brain plasticity has lead to new approaches in ischemic stroke rehabilitation. Stroke units that combine good medical and nursing care with task-oriented intense training in an environm

Bond Breaking, Electron Pushing, and Proton Pulling: Active and Passive Roles in the Interaction between Aqueous Ions and Water as Manifested in the O 1s Auger Decay

A core-ionized H(2)O molecule in liquid water primarily relaxes through normal Auger decay, leading to a two-hole final state in which both valence holes are localized on the same water molecule. Electronic coupling to the environment, however, allows for alternative decays resembling Intermolecular Coulombic Decay (ICD), producing final states with one of the holes delocalized on a neighboring wa

Mapped Bodies : Notes on the Use of Biometrics in Geopolitical Contexts

“Mapped Bodies: Notes on the Use of Biometrics in Geopolitical Contexts” examines the role played by automated biometric technologies in migration control and in the so-called war on terror. Biometric methods such as automated fingerprint identification, iris scanning and facial recognition record microscopic bodily characteristics, computes patterns from them, and matches those patterns against a

Lesion size affects diagnostic performance of IOTA logistic regression models, IOTA simple rules and risk of malignancy index in discriminating between benign and malignant adnexal masses

Objectives To estimate the ability to discriminate between benign and malignant adnexal masses of different size using: subjective assessment, two International Ovarian Tumor Analysis (IOTA) logistic regression models (LR1 and LR2), the IOTA simple rules and the risk of malignancy index (RMI). Methods We used a multicenter IOTA database of 2445 patients with at least one adnexal mass, i.e. the dat

Latin Letters from Clergymen in the Province of Scania (Eastern Denmark - Southern Sweden) in the Seventeenth Century : A Critical Edition with Introduction, Translation and Commentaries

This doctoral thesis comprises a critical edition of a previously unpublished manuscript from the late seventeenth century, which is housed in Lund University Library. The manuscript consists of copies of eighty-eight letters and other documents in Latin. The originals were, in most cases, written by country vicars from Scania, a Swedish province that until 1658 was part of Denmark. The identity o

Perfect or Imperfect Learning : Teaching the "Tenses" of Biblical Hebrew

The article discusses the pedagogical challenges inherent in teaching the “tenses” of Biblical Hebrew. How does one cope with explaining the intricacies and scholarly uncertainties of this question to beginners – and to what level is it advisable to do so? The author also examines the possible benefits of imparting a deeper understanding of these issues beyond the domain of the classroom.

Occupational Accidents Among Elderly Farmers in Sweden

The workforce in many countries nowadays is becoming older due to demographic change. Compared with many other occupations, farmers often work until a higher age. This study analysed occupational accidents to farmers in Sweden from an age perspective using data on 223 work injuries on farms and 990 road accidents involving tractors. The results showed that older farmers were not significantly more

Improving simultaneous saccharification and co-fermentation of pretreated wheat straw using both enzyme and substrate feeding.

ABSTRACT: BACKGROUND: Simultaneous saccharification and co-fermentation (SSCF) has been recognized as a feasible option for ethanol production from xylose-rich lignocellulosic materials. To reach high ethanol concentration in the broth, a high content of water-insoluble solids (WIS) is needed, which creates mixing problems and, furthermore, may decrease xylose uptake. Feeding of substrate has alre

Directional analysis of measured 60 GHz indoor radio channels using SAGE

Abstract in Undetermined Directional properties of the radio channel are of high importance for the development of reliable wireless systems operating in the 60 GHz frequency band. Using transfer functions measured from 61 to 65 GHz in a conference room we have extracted estimates of the multi-path component parameters using the SAGE algorithm. In the paper we compare results for line-of-sight (LO

Impact on image quality and radiation exposure in coronary CT angiography: 100 kVp versus 120 kVp

Background: The risk of radiation-induced cancer has become a major concern with the increasing use of computed tomography (CT). Purpose: To compare image quality and radiation doses when decreasing X-ray tube peak kilovoltage (kVp) from 120 to 100 kVp in patients undergoing coronary CT angiography (CCTA). Material and Methods: Patients referred for evaluation of suspected coronary artery disease

Cavity-enhanced storage-preparing for high-efficiency quantum memories

Cavity-assisted quantum memory storage has been proposed for creating efficient (close to unity) quantum memories using weakly absorbing materials. Using this approach, we experimentally demonstrate a significant (similar to 20-fold) enhancement in quantum memory efficiency compared to the no cavity case. A strong dispersion originating from absorption engineering inside the cavity was observed, w
