A solid phase extraction (SPE) technique has been developed for the quantitative determination of polyaromatic hydrocarbons (PAHs) in aqueous samples. The SPE technique involved extraction of PAHs from a 100 mL sample containing 10 % methanol as a modifier onto C-18 cartridges. 40 % methanol in water was used as conditioning solvent, and 3 mL acetone:THF (1:1) as eluting solvent. After eluting, th

Friluftsmuseer som Kulturen erbjuder sina besökare rika upplevelser av det förflutna genom de bevarade kulturmiljöerna som har flyttats in och levandegjorts. Museernas kulturmiljöer kan ibland uppfattas som oföränderliga, ja rentav tidlösa där de står år ut och år in, och där den enda förändring som tycks uppenbar är tidens tand som gnager på timret. Syftet med denna text är att utforska tradition

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

Study of film reception processes and Ingmar Bergman's film Shame (1968).

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

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

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

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

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

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

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

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

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

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

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

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

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
