Field-Scale Quality Control of Lime-Cement Pillar in Conductive Clay Using Electrical Resistivity Tomography

Ground improvement with lime-cement pillars is becoming increasingly common in the Nordic countries for exploitation of areas with poor stability. However, there is no non-destructive method for quality control of the ground improvement. Significant changes in the electrical properties after mixing of the binders make electrical resistivity tomography (ERT) a potential method. In connection with l

HΛ3 and H‾Λ‾3 lifetime measurement in Pb–Pb collisions at sNN=5.02 TeV via two-body decay

An improved value for the lifetime of the (anti-)hypertriton has been obtained using the data sample of Pb–Pb collisions at sNN=5.02 TeV collected by the ALICE experiment at the LHC. The (anti-)hypertriton has been reconstructed via its charged two-body mesonic decay channel and the lifetime has been determined from an exponential fit to the dN/d(ct) spectrum. The measured value, τ=242−38 +34 (sta

Air inlet angle influence on the air-side heat transfer and flow friction characteristics of a finned oval tube heat exchanger

In this study, the influence of various air inlet angles on the heat transfer and flow friction characteristics of a 2-row plain finned oval tube heat exchanger is analyzed by experimental and numerical methods. The experimental results show that an air inlet angle 45° provides the best heat transfer performance, and an air inlet angle 90° provides the smallest pressure drop, while an air inlet an

Identifying multidisciplinary research gaps across Arctic terrestrial gradients

Global warming is driving environmental change in the Arctic. However, our current understanding of this change varies strongly among different environmental disciplines and is limited by the number and distribution of field sampling locations. Here, we use a quantitative framework based on multivariate statistical modeling to present the current state of sampling across environmental disciplines

The role of the hydrological cycle in forest ecosystems : flow path, nutrient cycling and water-carbon interaction

Forest ecosystems, covering over a third of land on the Earth, play a significant role in the global hydrological cycle, and influence soil erosion and climate change. However, the distribution, movements, quality of water, and hydrological processes in forested ecosystems are not well understood yet.

Drama- och föreställningsanalys

Boken syftar till att ge en grundlig introduktion till teatern som kommunikationsform, fördjupa och vidga förståelsen för dramat och iscensättningen, ringa in teaterns egenart och tillhandahålla analytiska verktyg som behövs för att öppna dramat och teatern för vår förståelse och vår fantasi.

Spatio-temporal patterns of traffic-related air pollutant emissions in different urban functional zones estimated by real-time video and deep learning technique

The aim of this paper is to explore the relationship between spatial-temporal patterns of vehicles types and numbers in different urban functional zones and traffic-related air pollutant emissions with real-time traffic data collected from traffic surveillance video and image recognition. The data were analyzed by using video-based detection technique, while the air pollution was quantified via po

Cognitive reserve and clinical progression in Alzheimer disease : A paradoxical relationship

OBJECTIVE: To investigate the relationship between cognitive reserve (CR) and clinical progression across the Alzheimer disease (AD) spectrum. METHODS: We selected 839 β-amyloid (Aβ)-positive participants with normal cognition (NC, n = 175), mild cognitive impairment (MCI, n = 437), or AD dementia (n = 227) from the Alzheimer's Disease Neuroimaging Initiative (ADNI). CR was quantified using standa

Structure and spectrum of the hydrated electron. A combined quantum chemical statistical mechanical simulation

In the current work, in order to model a free electron solvated in water, we have implemented a method to represent the molecular charge distribution as a set of Slater-type functions within the framework of a QM/MM method called QMSTAT. Also, it has been introduced in this method a new approach to calculate the intermolecular induction energy in the presence of very strong electric fields. Unlike

Symptom-specific effects of cognitive-behavioral therapy, sertraline, and their combination in a large randomized controlled trial of pediatric anxiety disorders

Background: Pediatric anxiety disorders are highly prevalent and associated with significant functional disabilities and lifelong morbidity. Cognitive-behavioral therapy (CBT), sertraline, and their combination are effective treatments, but little is known about how these treatments exert their effects.Methods: Using network intervention analysis (NIA), we analyzed data from the largest randomized
