Subarctic atmospheric aerosol composition: 3. Measured and modeled properties of cloud condensation nuclei

Aerosol particles can modify cloud properties by acting as cloud condensation nuclei (CCN). Predicting CCN properties is still a challenge and not properly incorporated in current climate models. Atmospheric particle number size distributions, hygroscopic growth factors, and polydisperse CCN number concentrations were measured at the remote subarctic Stordalen mire, 200 km north of the Arctic Circ

Extraction of oxide traps in III-V MOSFETs using RF transconductance measurements

We here present simulations of the effect of border traps on the behavior of a III-V FET's transconductance with respect to frequency. We also compare simulations with a recently developed analytical model for extracting the border trap distribution through measurements of the transconductance, find good agreement between the extracted and simulated transconductance.

Increased cancer risks among arthroplasty patients: 30year follow-up of the Swedish Knee Arthroplasty Register.

BACKGROUND: An increasing number of young patients are undergoing knee arthroplasties. Thus, the long-term risks of having a knee prosthesis must be evaluated. This study focuses on the potential carcinogenic effects of the prosthesis; it is a long-term follow-up of all patients in Sweden between 1975 and 2006. METHODS: The incidence of cancer in a total population of operated individuals was comp

The use of plants as a “green factory” to produce high strength gluten-based materials

The aim of the present study was to develop an understanding of how wheat plants can be used as a “green factory” by the modulation of genotype (G) and environmental (E) interactions to fine-tune the structure and increase the strength of gluten based materials. Two wheat genotypes (5 + 10 and 2 + 12) were grown under four nitrogen and two temperature regimes to obtain gluten of various characteri

Family history and its association to curve size and treatment in 1,463 patients with idiopathic scoliosis

To study family history in relation to curve severity, gender, age at diagnosis and treatment in idiopathic scoliosis. A self-assessment questionnaire on family history of scoliosis was administered to 1,463 untreated, brace or surgically treated idiopathic scoliosis patients. Out of the 1,463 patients, 51 % had one or more relatives with scoliosis. There was no significant difference between fema

Risk of Hypertension Among Young Adults Who Were Born Preterm: A Swedish National Study of 636,000 Births

Previous studies have reported an association between preterm birth and elevated blood pressure in adolescence and young adulthood. These studies were based on single-day blood pressure measurements and had limited ability to estimate risk of hypertension measured over a longer period and across the full range of gestational ages. The authors conducted a national cohort study of all infants born i

Seeking alternative researcher identities in newcomer academic institutions in Sweden

Proliferating excellence gold standards in the global academic system tend to obscure the far-reaching diversification of academic missions, practices, ambitions and identities brought by massification. This article approaches this topic by a review of theory on academic scholarship and how it has changed in the wake of academic massification and the development of binary higher education systems.

Differential regulation of HIF-1α and HIF-2α in neuroblastoma: Estrogen-related receptor alpha (ERRα) regulates HIF2A transcription and correlates to poor outcome.

Hypoxia-inducible factors (HIFs) are differentially regulated in tumor cells. While the current paradigm supports post-translational regulation of the HIF-α subunits, we recently showed that hypoxic HIF-2α is also transcriptionally regulated via insulin-like growth factor (IGF)-II in the childhood tumor neuroblastoma. Here, we demonstrate that transcriptional regulation of HIF-2α seems to be restr

A feasible computer-based evaluation tool for reduction mammaplasty patients: Indications for operation and monitoring of guidelines.

In Sweden, evidence-based national guidelines for the indication for reduction mammaplasty in the public health-care system have been developed by a group of experts. They were defined as breast volume ≥800 ml at normal weight. Furthermore, a volume asymmetry of 25% or at least 200 ml or an extreme ptosis may be an indication in some cases. The aim of the present paper was to describe an easy-to-u

Exploring the link between MORF4L1 and risk of breast cancer

Introduction: Proteins encoded by Fanconi anemia (FA) and/or breast cancer (BrCa) susceptibility genes cooperate in a common DNA damage repair signaling pathway. To gain deeper insight into this pathway and its influence on cancer risk, we searched for novel components through protein physical interaction screens. Methods: Protein physical interactions were screened using the yeast two-hybrid syst

Strategy and Alignment in a Restricted Transitional Economy: Empirical Research on its Application to Iranian State-Owned Enterprises

Successful innovation strategy relies on experience gained from a complexity of understanding, anticipating and managing the global business environment. But, although much research has examined strategies of private sector organizations in Western economies, there are relatively few studies of innovation in public sector organizations of transitional and protected economic environments, such as I

Measurement of compton scattering from the deuteron and an improved extraction of the neutron electromagnetic polarizabilities.

The electromagnetic polarizabilities of the nucleon are fundamental properties that describe its response to external electric and magnetic fields. They can be extracted from Compton-scattering data-and have been, with good accuracy, in the case of the proton. In contradistinction, information for the neutron requires the use of Compton scattering from nuclear targets. Here, we report a new measur

Rim Sign in Breast Lesions on Diffusion-Weighted Magnetic Resonance Imaging: Diagnostic Accuracy and Clinical Usefulness

PurposeTo investigate the diagnostic accuracy and clinical usefulness of the rim sign in breast lesions observed in diffusion-weighted magnetic resonance imaging (DWI). Materials and MethodsThe magnetic resonance imaging (MRI) findings of 98 pathologically confirmed lesions (62 malignant and 36 benign) in 84 patients were included. Five breast radiologists were asked to independently review the br

Continuous wafer-scale graphene on cubic-SiC(001)

The atomic and electronic structure of graphene synthesized on commercially available cubic-SiC(001)/Si(001) wafers have been studied by low energy electron microscopy (LEEM), scanning tunneling microscopy (STM), low energy electron diffraction (LEED), and angle resolved photoelectron spectroscopy (ARPES). LEEM and STM data prove the wafer-scale continuity and uniform thickness of the graphene ove

Inflammation without neuronal death triggers striatal neurogenesis comparable to stroke.

Ischemic stroke triggers neurogenesis from neural stem/progenitor cells (NSPCs) in the subventricular zone (SVZ) and migration of newly formed neuroblasts towards the damaged striatum where they differentiate to mature neurons. Whether it is the injury per se or the associated inflammation that gives rise to this endogenous neurogenic response is unknown. Here we showed that inflammation without c

Upper Cambrian (Furongian) biostratigraphy in Scandinavia revisited: definition of superzones

The traditional Furongian trilobite biozones of Scandinavia, recently proposed abandoned due to inconsistent boundary definitions [Terfelt, F., Eriksson, M.E., Ahlberg, P. & Babcock, L.E., 2008: Furongian Series (Cambrian) biostratigraphy of Scandinavia - a revision. Norwegian Journal of Geology88, 73-87], are resurrected and elevated to superzonal rank. These superzones are usually readily re

Gender and Transition in Climate Governance

This article demonstrates how gender is implicated in climate governance through insights derived from gender and transition studies in combination, applied and illustrated through a study of climate governance in Sweden. The approach is constructive and uses central analytical concepts: transition arenas, niches, regimes and landscapes together with insights from gender research. The article prop

Panel versus GARCH Information in Unit Root Testing with an Application to Financial Markets

In search for more powerful unit root tests, some researchers have recently proposed accounting for the information contained in the GARCH of the innovations. However, while promising, tests with GARCH are difficult to implement, which has made them quite uncommon in the empirical literature. A computationally attractive alternative is to account not for GARCH but the information contained in a pa
