Purpose - The purpose of this paper is to present numerical investigation of the gas/vapor bubble dynamics under the influence of an ultrasonic field to give a more comprehensive understanding of the phenomenon and present new results Design/methodology/approach - In order to formulate the mathematical model, a set of governing equations for the gas inside the bubble and the liquid surrounding it

An increasing number of patients are successfully resuscitated from cardiac arrest (CA) and subsequently treated in an intensive care unit due to unconsciousness. Approximately half of these patients will die during the first weeks postarrest, typically after a determination of a poor neurologic prognosis and a decision to withdraw life-sustaining therapy (WLST). These decisions are guided by univ

Förbränning är både vår största källa till energi och ett stort hot mot miljön i form av föroreningar och växthusgaser. Ett par av de stora bovarna i sammanhanget är koldioxid och kväveoxider och de stora mängderna av dessa i atmosfären. Där bidrar koldioxid till den globala uppvärmningen i egenskap av växthusgas. Kväveoxider påverkar både miljö och människors hälsa negativt genom att bilda marknäCombustion of fuels is a major source of energy and at the same time a threat to the environment. Carbon dioxide (CO2) emissions are one of the obstacles on the route to cleaner energy. Combining Carbon Capture and Storage-technology (CCS) with use of biofuels lead to a negative net release of CO2 can be achieved. With some CCS-techniques the CO2 is repurposed in the combustion process together wi

Since I finished my PhD thesis in June 2014, I have lived a stimulating but also somewhat precarious life at Lund University. It is no secret that permanent teaching positions are hard to come by, and during the time I have been teaching as temporary staff on a number of different courses, I have started to consider what the lack of permanent positions means for the pedagogical work carried out at

Background/Aims: Increasing evidence suggests a link between brain-derived neurotrophic factor (BDNF) and suicidal behaviour (SB). Furthermore, decreased peripheral BDNF levels have been associated with clinical symptoms in various psychiatric disorders as well as with personality dimensions in healthy individuals. However, the relationship between BDNF and psychopathology is poorly investigated r

A case of acute interstitial nephritis caused by sodium valproate is reported. The sodium valproate treatment was continued after initial diagnosis and the patient developed end-stage renal failure. After transplantation, interstitial nephritis was demonstrated in the renal graft.

A majority of households in developing countries use biomass energy for cooking and heating due to its affordability and accessibility. However, unsustainable biomass use leads to deforestation, environmental degradation and climate change. The pollution from open burning of biomass is a major health concern especially for women and children as they spend a lot of time in the kitchen. Biochar-prod

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

Purpose: The purpose of this paper is to describe a review of the most frequently cited English articles of five models of collaborative professional development for mathematics teachers, aiming to describe the character of the development addressed and its quality issues. Design/methodology/approach: The most frequently cited articles were chosen for their impact on the scientific discourse; they

Purpose – The purpose of this paper is to describe a learning study with a complex object of learning – democracy. Design/methodology/approach – The study consists of four research lessons in four different classes in grade 6. In the study two teachers, 78 students and two researchers participated. In the first lesson (A) 21 students participated, in the second class (B) 17, in the third class (C)

This article seeks to explore the internal and external struggles and battles within the Danish legal profession in the period 1922-1957. Following Bourdieu’s critique of the notion of professions, we provide an insight into how the Danish Bar and Law Society have been shaped through internal power struggles. Our analysis shows that the Danish Legal profession is not a unit, but instead consists o
