Thermodynamic Assessment of the As-Zn and As-Ga-Zn Systems

We have performed a thermodynamic assessment of the As-Zn and As-Ga-Zn systems. The systems are assessed based on the CALPHAD method and using available first principles and experimental data. Using the optimized set of parameters found in this work, the calculated As-Zn binary phase diagram, isoplethal sections and the monovariants lines of the As-Ga-Zn ternary system are presented. The compariso

TRPA1 Receptor Induced Relaxation of the Human Urethra Involves TRPV1 and Cannabinoid Receptor Mediated Signals, and Cyclooxygenase Activation

Purpose: We studied whether TRPA1 agonists interact with sensory and inflammatory signals to relax human urethral smooth muscle. Materials and Methods: Urethral specimens were obtained perioperatively from 19 patients, and prepared for immunohistochemistry and functional experiments. The effects of allyl isothiocyanate, cinnamaldehyde and NaHS were studied in phenylephrine activated preparations c

Boosted objects and jet substructure at the LHC. Report of BOOST2012, held at IFIC Valencia, 23rd-27th of July 2012

This report of the BOOST2012 workshop presents the results of four working groups that studied key aspects of jet substructure. We discuss the potential of first-principle QCD calculations to yield a precise description of the substructure of jets and study the accuracy of state-of-the-art Monte Carlo tools. Limitations of the experiments' ability to resolve substructure are evaluated, with a focu

Fight and flight in dinoflagellates? Kinetics of simultaneous grazer-induced responses in Alexandrium tamarense

We monitored the kinetics of grazer-induced responses in the marine dinoflagellate Alexandrium tamarense. Chemical cues from each of three calanoid copepods (Calanus sp., Centropages typicus, and Acartia tonsa) induced increased toxicity and suppressed chain formation in A. tamarense. Both chemical and morphological responses augmented over 3 d. Toxicity subsequently averaged 299% higher than cont

Cholinergic and dopaminergic aspects of dementia in Parkinson's disease: postmortem neuropathological findings and modeling of cognitive dysfunction in rodents

Motor symptoms are currently considered the first clinical hallmark of Parkinson’s disease (PD). They develop as a result of dopamine loss in the striatum, subsequent to the progressive neurodegeneration of dopamin- ergic neurons in the substantia nigra. However, non-motor symptoms are frequent in PD patients and can greatly affect their quality of life. Among these, cognitive impairment affects p

Intersektionalitet och religiös förändring

Categories frequently discussed in terms of intersectionality are gender, class, race, ethnicity and sexual orientation. This article argues that, often, religion is also a relevant dimension in intersectional analyses. The concept "religious proximity" is therefore introduced as an analytical tool which will facilitate a more complex analysis of situations where a religious dimension interacts wi

High-order harmonic generation with mu J laser pulses at high repetition rates

We investigate the generation of high-order harmonics using laser pulse energies in the few-mu J range at high repetition rates. We analyse how the conversion efficiency is influenced by the tight focusing geometry required for the generation of high-order harmonics under these conditions. A generalized phase-matching model allows us to discuss macroscopic phase effects independent of focal length

Steroid hormone measurements from different types of assays in relation to body mass index and breast cancer risk in postmenopausal women: Reanalysis of eighteen prospective studies

Epidemiological studies have examined breast cancer risk in relation to sex hormone concentrations measured by different methods: "extraction" immunoassays (with prior purification by organic solvent extraction, with or without column chromatography), "direct" immunoassays (no prior extraction or column chromatography), and more recently with mass spectrometry-based assays. We describe the associa

Risk of Second Primary Cancers in Multiple Myeloma Survivors in German and Swedish Cancer Registries.

We aimed at investigating the distribution and risk of second primary cancers (SPCs) in multiple myeloma (MM) survivors in Germany and Sweden to provide etiological understanding of SPCs and insight into their incidence rates and recording practices. MM patients diagnosed in 1997-2010 at age ≥15 years were selected from the Swedish (nationwide) and 12 German cancer registries. Standardized inciden

Possible Positive Selection for an Arsenic-Protective Haplotype in Humans

BACKGROUND: Arsenic in drinking water causes severe health effects. Indigenous people in the South American Andes have likely lived with arsenic-contaminated drinking water for thousands of years. Inhabitants of San Antonio de los Cobres (SAC) in the Argentinean highlands generally carry an AS3MT (the major arsenic-metabolizing gene) haplotype associated with reduced health risks due to rapid arse

Oblate deformation of light neutron-rich even-even nuclei

Light neutron-rich even-even nuclei, of which the ground state is oblately deformed, are looked for, examining the Nilsson diagram based on realisticWoods-Saxon potentials. One-particle energies of the Nilsson diagram are calculated by solving the coupled differential equations obtained from the Schrodinger equation in coordinate space with the proper asymptotic behavior for r -> infinity for both

Lipid soluble smoke particles up-regulate vascular smooth muscle ETB receptors via activation of mitogen activating protein kinases and NF-kappaB pathways.

Cigarette smoke is a strong risk factor for cardiovascular disease. However, the underlying molecular mechanisms that lead to cigarette smoke-associated cardiovascular disease remain elusive. With functional and molecular methods, we demonstrate for the first time that lipid soluble cigarette smoke particles (DSP) increased the expression of endothelin type B (ET(B)) receptors in arterial smooth m

Characterisation of a pre-cell hit detector to be used in single cell irradiation experiments at the Lund Nuclear Microprobe

This paper describes the characterisation of an ultra-thin silicon semicondoctor Delta E detector to be used as a pre-cell ion hit detector in single ion experiments on individual, living cells. The characteristics of interest for this specific application are the hit detection efficiency, which has to be close to 100% to enable bombardment with either a single ion or a counted number of ions, the

SLF:s höstexkursion till Skäckerfjällen 15-17 augusti 2008

Förra året beslutade SLF att 'adoptera' Skäckerfjällen i Jämtland, vilket innebär att föreningen avser att göra en fullständig inventering av dess lavar genom återkommande besök under ett antal år. Första besöket gjordes under höstexkursionen 2008 i mångahanda spännande miljöer, såsom kalkbranter, bäckraviner med gammal granskog, videsnår, snölegor och fjälltoppar med urberg. Exkursionen resultera

Accurate Localization and Pose Estimation for Large 3D Models

We consider the problem of localizing a novel image in a large 3D model. In principle, this is just an instance of camera pose estimation, but the scale introduces some challenging problems. For one, it makes the correspondence problem very difficult and it is likely that there will be a significant rate of outliers to handle. In this paper we use recent theoretical as well as technical advances t

Mercury in serum predicts low risk of death and myocardial infarction in Gothenburg women

Markers of mercury (Hg) exposure have shown both positive and negative associations with cardiovascular disease (CVD). We assessed the association between serum Hg (S-Hg) and risk of cardiovascular disease in a prospective population-based cohort, with attention to the roles of dental health and fish consumption. Total mortality, as well as morbidity and mortality from acute myocardial infarction
