Atmospheric CO2 sensing using Scheimpflug-lidar based on a 1.57-µm fiber source

A molecular laser-radar system, based on the Scheimpflug principle, has been constructed and demonstrated for remote sensing of atmospheric CO2 concentrations using Differential Absorption Lidar (DIAL) in the (30012←00001) absorption band. The laser source is a Continues Wave (CW) Distributed-FeedBack (DFB) diode laser seeding an Erbium-doped fiber amplifier, emitting narrowband (3 MHz) tunable ra

Effect of temperature on the formation of highly oxygenated organic molecules (HOMs) from alpha-pinene ozonolysis

Highly oxygenated organic molecules (HOMs) are important contributors to secondary organic aerosol (SOA) and new-particle formation (NPF) in the boreal atmosphere. This newly discovered class of molecules is efficiently formed from atmospheric oxidation of biogenic volatile organic compounds (VOCs), such as monoterpenes, through a process called autoxidation. This process, in which peroxy-radical

Highly enantioselective epoxidation of olefins by H 2 O 2 catalyzed by a non-heme Fe(ii) catalyst of a chiral tetradentate ligand

The chiral tetradentate N4-donor ligand, 1-methyl-2-({(S)-2-[(S)-1-(1-methylbenzimidazol-2-yl methyl)pyrrolidin-2-yl]pyrrolidin-1-yl}methyl) benzimidazole (S,S- PDBz L), based on a chiral dipyrrolidine backbone, has been synthesized and its corresponding Fe(ii) complex has been prepared and characterized. The X-ray structure of the complex reveals that the Fe(ii) ion is in a distorted octahedral

Factors influencing the outcome of renovation projects

Bostäder står för ca 23% av all energianvändning i Sverige. Om målet netto-nollkoldioxidutsläpp 2045 ska nås är det därför troligt att energibesparande åtgärderför bostäder kommer behövas. Många av de befintliga byggnaderna är runt 50 åreller äldre och är således i behov av modernisering. Samtidigt ökarurbaniseringstakten, därför finns det och kommer även framöver finnas behov avfler bostäder. EneIn Sweden, housing accounts for about 23% of all energy consumption. Sweden wants to reach net zero carbon emissions by 2045; as such, it is likely that energy-saving measures for housing will be needed. Many existing buildings have been in operation for 50 years or more and are therefore in need of modernisation. At the same time, the population is increasing and so is the rate of urbanisation, w

Clinical outcome of the 2nd generation cryoballoon for pulmonary vein isolation in patients with persistent atrial fibrillation - A sub-study of the randomized trial evaluating single versus dual cryoballoon applications

AIMS: To assess the efficacy of the 2nd generation Cryoballoon for pulmonary vein isolation (PVI) in patients with persistent atrial fibrillation (PersAF), and to compare it to patients with paroxysmal atrial fibrillation (PAF).METHODS: The outcome (arrhythmia recurrence at 12 months) was prospectively assessed in patients with PersAF(n = 77) and compared to that in patients with PAF(n = 62), who

Permanent pacemaker implantation early and late after heart transplantation : clinical indication, risk factors and prognostic implications

BACKGROUND: Permanent pacemaker implantation (PPM) early after cardiac transplantation has been shown not to predict a worse outcome. However, the requirement for pacing late after transplantation and its prognostic implications are not fully known. We describe the clinical indications, risk factors and long-term outcome in patients who required pacing early and late after transplantation.METHODS:

Structured Population-based Prostate-specific Antigen Screening for Prostate Cancer : The European Association of Urology Position in 2019

Prostate cancer (PCa)is one of the first three causes of cancer mortality in Europe. Screening in asymptomatic men (aged 55–69 yr)using prostate-specific antigen (PSA)is associated with a migration toward lower staged disease and a reduction in cancer-specific mortality. By 20 yr after testing, around 100 men need to be screened to prevent one PCa death. While this ratio is smaller than for breast

Seasonal co-variation of plant water storage, canopy greenness, and groundwater storage across the globe

Plant water storage is fundamental to the functioning of terrestrial ecosystems by participating in plant metabolism, nutrient and sugar transport, and maintenance of the integrity of the hydraulic system of the plant. However, a global view of the size and dynamics of the water pools stored in plant tissues is still lacking. Here, we report global patterns of seasonal variations in ecosystem-scal

Hip precautions not meaningful after hemiarthroplasty due to hip fracture. Cluster-randomized study of 394 patients operated with direct anterolateral approach

Aims: We aimed to compare two treatment regimes, one with and one without postoperative precautions in hemiarthroplasty patients, in terms of dislocation rate and patient-reported outcome. Direct lateral approach was used. Patients and Methods: 394 patients were included in a cluster-randomized study 2010−2014. Depending on which ward they were admitted to, they were allotted to free rehabilitatio

Academic Support using Peer Assisted Study Schemes (SI-PASS) to help new students with the transition to Higher Education. A European overview.

This presentation gives an overview of a peer learning model and academic support intervention named SI-PASS (Supplemental Instruction – Peer Assisted Study Schemes) in Higher Education in Europe. SI-PASS is a method of improving student performance in “difficult”, normally introductory, courses combining “how to learn” with “what to learn”. SI-PASS sessions are scheduled parallel to the regular e

Neighborhood Deprivation and Risks of Autoimmune Disorders : A National Cohort Study in Sweden

Background: No study to date, as far as we know, has analyzed the potential effect of neighborhood-level deprivation on autoimmune disorders (ADs), when adjusted for individual-level characteristics. Methods: A total of 5.4 million individuals from 8363 neighborhoods, comprising the whole Swedish population (ages 25-74 years), were followed for the period 1 January 2000, until admission due to dia

Atrial Fibrillation in Long QT Syndrome by Genotype

BACKGROUND: Long QT syndrome (LQTS) is caused by the abnormal function of ion channels, which may also affect atrial electrophysiology and be associated with the risk of atrial fibrillation (AF). However, large-scale studies of AF risk among patients with LQTS and its relation to LQTS manifestations are lacking. We aimed to assess the risk of AF and its relationship to the LQTS genotype and the lo
