Det finns energi att hämta i empiriska iakttagelser och det kan vara enfröjd att utvinna den energin. Så lyder budskapet i den här vänbokentill Malin Åkerström, professor emerita vid Lunds universitet.Med nedslag i vitt skilda fält och projekt vill författarna exemplifieraoch analysera det speciella samspel som äger rum mellan empirioch forskare i olika samhällsvetenskapliga ämnen. Det rör sig om

Simple but robust approaches were used to reveal the quantitative and statistically significant influence of the Southern Oscillation Index (SOI) on monthly precipitation at five stations distributed over South Korea and Fukuoka, Japan. The monthly precipitation data were transformed into non-exceedence probability time series. SOI is classified into five categories. Correlation between the catego

The Arctic has warmed more than twice the rate of the entire globe. To quantify possible climate change effects, we calculate wind energy potentials from a multi-model ensemble of Arctic-CORDEX. For this, we analyze future changes of wind power density (WPD) using an eleven-member multi-model ensemble. Impacts are estimated for two periods (2020–2049 and 2070–2099) of the 21st century under a high

Under mitt fältarbete kring graffiti var ”ska vi inte gå och ta en öl?” en återkommandeuppmaning bland deltagarna, även formulerad som ”gå ut och röka”, ”ta en promenad”, osv. Även om dessa förslag i sig knappast är unika för graffiti, visade sig deras betydelser och konsekvenser vara just det. I detta kapitel ska jag analysera hur dessa sociala uppmaningar användes som subkulturella eufemismer fö

Fluorescent probes based on photoinduced electron transfer (PET) quenching of long lifetime triangulenium fluorophores have found multiple applications. For such probes a successful design relies on the right balance between the rate of PET quenching and fluorescence. In a series of ADOTA (A) and DAOTA (D) triangulenium fluorophores appended with aniline-like quencher moieties, we have investigate

En teknik för att förhindra yterosion och samla ytavrinning är bygga jordvallar (1–1,5 m höga) parallellt medhöjdkurvorna. Denna teknik används över stora områden i Tunisien. I denna studie undersöks hur dessa jord-vallar påverkar ytjordens rumsliga variabilitet av markvattenhalt (θ) och salinitet, dels uttryckt som jordenstotala elektriska konduktivitet (σa) och dels som porvattnets elektriska koOne technique for collecting rainwater and prevent soil erosion applied on large areas in Tunisia involves theuse of soil ridges (1–1.5 m high). These contour ridges are constructed parallel to topographical isolines. Theeffects of the contour ridges on the soil water content (θ) distribution, bulk soil salinity σa, and soil water salin-ity (σw) were investigated in the catchment of El-Gouazine in

Background: Healing failure after rotator cuff repair is a challenging problem. Acute, trauma-related tears are considered a separate entity and are often treated surgically. The aim of this study was to identify factors associated with healing failure in previously asymptomatic patients with trauma-related rotator cuff tears treated with early arthroscopic repair. Methods: This study included 62

This paper addresses the hybrid quantized signal detection problem in a distributed radar system, where widely separated antennas transmit low-bit quantized data with varying quantization levels depending on the different bandwidth constraint for each channel to a fusion center. To enable a high detection performance with such hybrid quantized data, we formulate the generalized likelihood ratio, R

Attosecond photoelectron spectroscopy has opened up for studying light–matter interaction on ultrafast time scales. It is often performed with interferometric experimental setups that require outstanding stability. We demonstrate and characterize in detail an actively stabilized, versatile, high spectral resolution attosecond beamline based on a Mach-Zehnder interferometer. The active stabilizatio

We present a high-repetition rate, atttosecond light source, emitting controlled short trains of attosecond pulses. We apply this source to the study of photoionization of atoms using a 3D photoelectron/ion coincidence spectrometer.

This Massive Open Online Course (MOOC), offered in partnership with online learning provider Coursera, is a free resource for university students who are currently involved in writing assignments or degree projects as well as for students who wish to learn about academic writing in order to prepare for future writing tasks at university. Although the course provides guidance to all student writers

Background: The optimal first-line treatment in early rheumatoid arthritis (RA) is debated. We compared clinical and radiographic outcomes of active conventional therapy with each of three biological treatments with different modes of action. Methods: Investigator-initiated, randomised, blinded-assessor study. Patients with treatment-naïve early RA with moderate-severe disease activity were random

In South Africa, the family Heliozelidae in the order Lepidoptera is restricted to four known species. The grapevine leaf miner, Holocacista capensis, feeds between the epidermal layers of a grapevine leaf, predominantly along the leaf margin. A final instar larva will descend from the blotch mine/gallery to attach its cocoon casing (constructed from the epidermal layers of the mined gallery) to a

Children with cancer experience fragmented school attendance during treatment. Telepresence robots that connect them with school during treatment periods were explored through an intervention involving participant observation followed by semi-structured interviews from 2020–22 with children with cancer, their class teachers, and classmates. We used an abductive approach, inspired by the Agential R
