Urbanization transforms environments in ways that alter biological evolution. We examined whether urban environmental change drives parallel evolution by sampling 110,019 white clover plants from 6169 populations in 160 cities globally. Plants were assayed for a Mendelian antiherbivore defense that also affects tolerance to abiotic stressors. Urban-rural gradients were associated with the evolutio
Lubrication has been proven to be an effective approach to drastically improve the efficiency of ultrasonic motors without losing the output torque. This phenomenon is attributed to the effective modulation of the friction force by lubricant, according to the theory described in the Stribeck curve. Previous findings even show a potential to increase the motor output torque with lubrication. Here,
Temperature and coagulant types have an important impact on the quantity and quality of the residue (sludge) in water and wastewater treatment processes. Temperature influences water viscosity and the distribution of the coagulant in water. Coagulants can promote the agglomeration of fine particles into larger flocs so that they can be more easily separated from the water. Experiments have been co
This study analyzes how risk attitudes influence the agricultural productivity of men and women in a sub- Saharan African country, Burkina Faso. By using a large representative panel survey of farmers, the results show that as female farmers increase risk taking, the productivity of female-owned plots goes down. The study controls for various socio-economic factors and explores how the diversity oThis study analyzes how risk attitudes influence the agricultural productivity of men and women in a sub- Saharan African country, Burkina Faso.

The cross-section average (CA) augmentation approach of Pesaran (A simple panel unit root test in presence of cross-section dependence. Journal of Applied Econometrics 2007; 22: 265–312) and Pesaran et al. (Panel unit root test in the presence of a multifactor error structure. Journal of Econometrics 2013; 175: 94–115), and the principal components-based panel analysis of non-stationarity in idios
This paper studies the nexus between income and wealth inequality, and the ecological footprint in the United States and France from 1962 to 2021. Based on theoretical considerations, we allow the relationship to vary over time. We find some support for income inequality affecting the ecological footprint in the United States and that the relationship has changed over time. We find no such result
Objectives: This study investigated comorbidity in chemical intolerance (CI) and building-related intolerance (BRI) with (i) chronic sinusitis, chronic obstructive pulmonary disease, allergic and nonallergic asthma and allergic rhinitis, and (ii) airway inflammatory symptoms. Methods: Data from two population-based questionnaire surveys, the Västerbotten and Österbotten Environmental Health Studie
An interleaved pseudocinematographic FLASH (fast low-angle shot) sequence with additional pulsed gradients for flow encoding was used to quantify cerebrospinal fluid (CSF) flow velocities and CSF production. Flow-dependent phase information was obtained by subtracting two differently encoded phase images. The phase information in the resultant image was converted to flow velocity with a calibratio
This letter proposes a novel wideband, single-layer monopolar antenna with high selectivity and enhanced pattern stability across the operating band. Building upon a conventional circular patch antenna, the rejection levels of the upper and lower sidebands are carefully analyzed, designed, and optimized to achieve the desired performance. To further improve performance, a shorting-via-loaded ring
OBJECTIVES: The purpose of the present study was to assess the effect, on miscarriages and stillbirths, of persistent organochlorine compounds (POC) through dietary intake of fatty fish from the Baltic Sea. METHODS: Information on miscarriages and stillbirths was collected retrospectively by a self-administered questionnaire in a cohort of fishermen's wives from the Swedish east coast (by the Balt
Aim: Examine the effect of a 10 h intervention programme compared with post-mailed minimal intervention (PMMI) given to high-risk alcohol-drinking university freshmen in a random design. Method: In total 693 freshmen at the Lund Institute of Technology, Lund University, Sweden were included in the study. A cognitive behavioural alcohol program (CBAP) or PMMI was given to high-risk drinking freshme
Abstract in Undetermined Imagining Mass Dictatorship is the fifth volume in the ‘Mass Dictatorship’ series launched by Hanyang University's Research Institute of Comparative History and Culture and published by Palgrave. It sees twelve Swedish and Korean scholars, theorists, and historians of fiction and non-fiction probe the literary subject of life in 20th century mass dictatorships. Generously
Resolving the genetic basis of complex diseases like rheumatoid arthritis will require knowledge of the corresponding diseases in experimental animals to enable translational functional studies. Mapping of quantitative trait loci in mouse models of arthritis, such as collagen-induced arthritis (CIA), using F-2 crosses has been successful, but can resolve loci only to large chromosomal regions. Usi
Apoptosis of endothelial cells (ECs) has been suggested to play a role in atherosclerosis. We studied the synergism of hypercholesterolemia with Chlamydia pneumoniae and influenza virus infections on EC morphology and intimal changes in a minipig model. The coronary artery was excised at euthanasia (19 weeks of age) and serial sections were processed for the detection of EC apoptosis, histology, a

Laparoscopic cholecystectomy (LC) is attempted in all our patients scheduled for cholecystectomy. The related standard radiologic procedures are preoperative ultrasonography (US) and preoperative cholangiography (PCA). In a retrospective study of 214 patients scheduled for LC over a 2-year period we have reviewed the radiologic and clinical records. Preoperative US revealed stones in the common bi
