Geoelectrical imaging for detection of water migration in a bioreactor landfill

In this paper we describe field investigations of leachate recirculation at a bioreactor landfill using geoelectrical imagining technique (i.e., electrical resistivity) combined with a tracer test. The use of geoelectrical imagining techniques is an established practice for environmental investigations and monitoring of various landfill processes and in recent years also the bioreactor landfill co

Familial risks in nervous system tumors

We used the nationwide Swedish Family-Cancer Database to analyze the risk for nervous system tumors in offspring through parental and sibling probands. Among 0-68-year-old offspring, close to 11000 patients with a nervous system tumor were identified in years 1961 to 2000, among whom 199 had a parent diagnosed with a nervous system tumor. Brain tumors constituted 86% of all tumors, and astrocytoma

The nature of damped HI absorbers probed by cosmological simulations: satellite accretion and outflows

We use cosmological hydrodynamic zoom simulations to study the neutral gas distributionin and around galaxies that gives rise to high column density HILyαabsorption (dampedLyαsystems (DLAs) and sub-DLAs) in background quasar spectra. Such simulations oftensacrifice numerical resolution for volume that affects the lower density galaxy halo gas,and simulations have difficulties reproducing the span

DEVICE FOR GENERATING TEMPORALLY OFFSET , SPATIALLY MODULATED ILLUMINATION REGIONS

A device is provided for generating temporally offset , spa tially modulated illumination regions (22 , 22 ') having peri odic modulation patterns that are phase - shifted with respect to one another . The device has two pulsed laser sources (121 , 122) that are triggerable in a manner temporally offset with respect to one another and that generate two laser beams pulsed in a temporally offset man

Low Testosterone, but Not Estradiol, Is Associated With Incident Falls in Older Men : The International MrOS Study

Fracture risk is determined by bone strength and the risk of falls. The relationship between serum sex steroids and bone strength parameters in men is well known, whereas the predictive value of sex steroids for falls is less studied. The aim of this study was to assess the associations between serum testosterone (T) and estradiol (E2) and the likelihood of falls. Older men (aged ≥65 years) from t

Effects of multiparity and prolonged breast-feeding on maternal bone mineral density : a community-based cross-sectional study

Background: Studies conducted in Western countries have shown that bone loss associated with pregnancy and breast-feeding is recovered after weaning. However, it is not clear whether recovery takes place after repeated pregnancies followed by prolonged periods of breast-feeding; especially in developing countries where nutritional intake is comparatively low.This study was designed to examine the

Is there a weekend effect in surgery for type A dissection? - Results from the NORCAAD database

BACKGROUND: Aortic dissection type A requires immediate surgery. In general surgery populations, patients operated during weekends have higher mortality rates compared to patients operated on weekdays. The weekend effect in aortic dissection type A has not been studied in detail.METHODS: The Nordic Consortium for Acute Type A Aortic Dissection (NORCAAD) registry includes patients (N=1,159) who und

An exon 5 deletion variant of the estrogen receptor frequently coexpressed with wild-type estrogen receptor in human breast cancer

Recent evidence suggests that the expression of estrogen receptor (ER) variants in breast cancer may interfere with wild-type (wt) ER function and be related to tumor progression and resistance to hormone treatment. One of these variants, ER delta E5, lacking that part of the hormone-binding domain encoded by exon 5, has previously been identified in breast tumors with the unusual estrogen recepto

När slutade reformationen? : Reformation, konfessionalisering och representationen av Martin Luther i svensk bokproduktion under 1500-talet

When did the Reformation end? Reformation, confessionalization and the representation of Martin Luther in Swedish 16th-century printIn the past decades, Swedish scholars have used the concept of the Reformation to refer to a long process of religious change in Sweden between 1527 and 1593. The influence from the term ”the long reformation” used in the Anglo-Saxon world is tangible. Instead, this e

Cognitive functioning and aggressive antisocial behaviors in young violent offenders

Studies have shown that offenders have impaired cognitive abilities yet it is unclear if cognitive dysfunction per se contributes to aggressive antisocial behaviors. Our aims were to (1) determine associations between cognitive functioning and different forms of aggressive antisocial behaviors, (2) describe prevalence of, and covariates to, uneven intellectual profiles, and (3) investigate associa

Ewing sarcoma of the mobile spine; predictive factors for survival, neurological function and local control. A Scandinavian sarcoma group study with a mean follow-up of 12 years

Object: Many patients with Ewing sarcoma (ES) of the mobile spine present with neurologic symptoms leading to emergency decompressive surgery. Only rarely is optimal treatment involving neo-adjuvant chemotherapy followed by en bloc excision possible. The purpose of this study was to study treatment, neurologic and oncologic outcome in patients with ES of the mobile spine. Methods: Twenty-four pati

A stochastic process approach to multilayer neutron detectors

The sparsity of the isotope Helium-3, ongoing since 2009, has initiated a new generation of neutron detectors. One particularly promising development line for detectors is the multilayer gaseous detector. In this paper, a stochastic process approach is used to determine the neutron energy from the additional data afforded by the multilayer nature of these novel detectors. The data from a multilaye

Automated Operant Assessments of Huntington's Disease Mouse Models

Huntington's disease (HD) presents clinically with a triad of motor, cognitive, and psychiatric symptoms. Cognitive symptoms often occur early within the disease progression, prior to the onset of motor symptoms, and they are significantly burdensome to people who are affected by HD. In order to determine the suitability of mouse models of HD in recapitulating the human condition, these models mus

Microstructures of cellulose coagulated in water and alcohols from 1-ethyl-3-methylimidazolium acetate : contrasting coagulation mechanisms

Abstract: Coagulation of cellulose solutions is a process whereby many useful materials with variable microstructures and properties can be produced. This study investigates the complexity of the phase separation that generates the structural heterogeneity of such materials. The ionic liquid, 1-ethyl-3-methylimidazolium acetate ([C2mim][OAc]), and a co-solvent, dimethylsulfoxide (DMSO), are used t

Biomarkers for tau pathology

The aggregation of fibrils of hyperphosphorylated and C-terminally truncated microtubule-associated tau protein characterizes 80% of all dementia disorders, the most common neurodegenerative disorders. These so-called tauopathies are hitherto not curable and their diagnosis, especially at early disease stages, has traditionally proven difficult. A keystone in the diagnosis of tauopathies was the d
