Pebble drift and planetesimal formation in protoplanetary discs with embedded planets
Nearly axisymmetric gaps and rings are commonly observed in protoplanetary discs. The leading theory regarding the origin of these patterns is that they are due to dust trapping at the edges of gas gaps induced by the gravitational torques from embedded planets. If the concentration of solids at the gap edges becomes high enough, it could potentially result in planetesimal formation by the streami
Impact of Body Position on Lung Deposition of Nebulized Surfactant in Newborn Piglets on Nasal Continuous Positive Airway Pressure
Introduction: The ideal body position during surfactant nebulization is not known. Objective: The aim of this study was to determine whether body positioning during surfactant nebulization influences surfactant distribution and deposition in the lungs. Methods: Twenty-four 12- to 36-h-old full-termpiglets (1.3-2.2 kg) on nasal continuous positive airway pressure (nCPAP) were randomized into four g
Impaired airway epithelial cell wound-healing capacity is associated with airway remodelling following RSV infection in severe preschool wheeze
Background: Respiratory syncytial virus (RSV) causes exacerbations of asthma and preschool wheeze (PSW). However, the anti-viral and repair responses of the bronchial epithelium in children with severe therapy-resistant asthma (STRA) and PSW are poorly understood. Methods: Children with STRA (age 12 [6-16] years), PSW (age 2 [1-5] years) and non-asthmatic controls (age 7 [2-14] years) underwent br
Impaired vibrotactile sense showed no association with insulinoma associated protein 2 and glutamic acid decarboxylase autoantibodies in paediatric type 1 diabetes
Selling women the green dream: the paradox of feminism and sustainability in fashion marketing
This article explores the paradox of corporations using social and environmental justice concerns to market products that are themselves made in conditions of environmental and social injustice, most often in the Global South. The effects of the fashion industry on people is two-pronged: 1) the unsafe and exploitative conditions under which many garment workers operate, and 2) the severe and harmf
Behavioral responses of male turnip moths, Agrotis segetum, to sex pheromone in a flight tunnel and in the field
The response of individual male turnip moths Agrotis segetum was observed in a sustained flight tunnel to a mixture of decyl acetate, (Z)-5-decenyl acetate, (Z)-7-dodecenyl acetate, and (Z)-9-tetradecenyl acetate in proportions similar to those found in gland extracts from virgin females (0.6: 1:5:2.5). Lures containing 3-30 μg (Z)-5-decenyl acetate proved to be maximally attractive, with approxim
”Operation Rimfrost bygger, liksom annat polisiärt arbete, på vetenskaplig grund.”
Den ekonomiska brottsligheten må vara högre i områden som Limhamn och Västra hamnen, men det är brott där polisen oftast inte behöver sätta in massiva razzior, skriver Ardavan Khoshnood, docent i akutsjukvård vid Lunds universitet och kriminolog.Economic crime may be higher in areas such as Limhamn and Västra hamnen, but these are crimes where the police usually do not need to launch massive raids, writes Ardavan Khoshnood, associate professor in emergency medicine at Lund University and criminologist.
Genomic imprinting analyses identify maternal effects as a cause of phenotypic variability in type 1 diabetes and rheumatoid arthritis
Imprinted genes, giving rise to parent-of-origin effects (POEs), have been hypothesised to affect type 1 diabetes (T1D) and rheumatoid arthritis (RA). However, maternal effects may also play a role. By using a mixed model that is able to simultaneously consider all kinds of POEs, the importance of POEs for the development of T1D and RA was investigated in a variance components analysis. The analys
Nuclear field theory predictions for 11Li and 12Be : Shedding light on the origin of pairing in nuclei
Recent data resulting from studies of two-nucleon transfer reaction on 11Li, analyzed through a unified nuclear-structure-direct-reaction theory have provided strong direct as well as indirect confirmation, through the population of the first excited state of 9Li and of the observation of a strongly quenched ground state transition, of the prediction that phonon-mediated pairing interaction is the
Dyson treatment of NFT medium polarization processes in superfluid nuclei
We discuss the solution of the Dyson equation (also known as the Nambu-Gor'kov equation) for the case of medium polarization Nuclear Field Theory (NFT) processes in nuclei, and apply it to the nucleus 120Sn. Starting from a mean field obtained with the Sly4 effective nucleon-nucleon force, (mk = 0.7), we renormalize the single-particle states and the pairing interaction through the coupling to col
A treatment planning and delivery comparison of volumetric modulated arc therapy with or without flattening filter for gliomas, brain metastases, prostate, head/neck and early stage lung cancer
Background. Flattening filter-free (FFF) beams are an emerging technology that has not yet been widely implemented as standard practice in radiotherapy centers. To facilitate the clinical implementation of FFF, we attempted to elucidate the difference in plan quality and treatment delivery time compared to flattening filter beams (i.e. standard, STD) for several patient groups. We hypothesize that
18F-FDG PET/CT for planning external beam radiotherapy alters therapy in 11% of 581 patients
Background: 18F-FDG PET/CT (FDG PET/CT) used in radiotherapy planning for extra-cerebral malignancy may reveal metastases to distant sites that may affect the choice of therapy. Aim: To investigate the role of FDG PET/CT on treatment strategy changes induced by the use of PET/CT as part of the radiotherapy planning. ‘A major change of treatment strategy’ was defined as either including more lesion
Health impacts from ambient particle exposure in southern sweden
A health impact assessment (HIA) is an important tool for making informed decisions regarding the design and evaluation of environmental interventions. In this study, we performed a quantitative HIA for the population of Scania (1,247,993), the southernmost county in Sweden, in 2016. The impact of annual mean concentrations of particulate matter with an aerodynamic diameter
The Gaia-ESO Survey : An extremely Li-rich giant in globular cluster NGC 1261
Lithium-rich stars in globular clusters are rare. Only 14 have been found so far, in different evolutionary phases from dwarfs to giants. Different mechanisms have been proposed to explain this enhancement, but it is still an open problem. Using spectra collected within the Gaia-ESO Survey, obtained with the GIRAFFE spectrograph at the ESO Very Large Telescope, we present the discovery of the firs
The HR 1614 moving group is not a dissolving cluster
Context. The HR 1614 is an overdensity in velocity space and has for a long time been known as an old (2 Gyr) and metal-rich ([Fe=H] +0:2) nearby moving group that has a dissolving open cluster origin. The existence of such old and metal-rich groups in the solar vicinity is quite unexpected since the vast majority of nearby moving groups are known to be young. Aims. In the light of new and signifi
Analyzing Hope : The Live Possibility Account
The orthodox definition of hope suffers from an exclusion problem: it is unable to exclude subjects without hope. In fact, the orthodox definition even allows for despair to be falsely classified as hope. This problem suggests two basic desiderata for a successful analysis of hope; it should solve the exclusion problem, and it should have the resources to explain why, in a given situation, a subje
A new equation of state applied to planetary impacts : I. Models of planetary interiors
We present a new analytical equation of state (EOS), which correctly models high pressure theory and fits well to the experimental data of E-Fe, SiO2, Mg2SiO4, and the Earth. The cold part of the EOS is modeled after the Varpoly EOS. The thermal part is based on a new formalism of the Gruneisen parameter, which improves behavior from earlier models and bridges the gap between elasticity and thermo
