Background: Residual air accumulated air in the pulmonary veins constitutes a challenge to achievment of complete de-airing in open left heart surgery. To adress this problem, a conceptual method for de-airing was developed in Lund comprising bilateral opening of the pleurae to induce pulmonary collapse and a strategy with gradual pulmonary reperfusion and ventilation at weaning from cardiopulmona
Today’s communities are characterized by migration, transnationalism, and participation in the global economy, and many also have long local histories of linguistic diversity. Empowering individuals in these contexts means fostering the ability to use and expand their existing linguistic repertoires so they can take advantage of the social and economic opportunities afforded by contemporary life.
Purpose We validate the usefulness of laser-induced autofluorescence for the detection of bladder carcinoma. Materials and Methods We obtained and analyzed fluorescence spectra from 75 patients in whom bladder cancer was suspected. Tissue fluorescence was excited by a nitrogen laser using a quartz optical fiber placed in gentle contact with the area of interest. The laser-induced autofluorescence
AL-Karama dam, the second largest dam in Jordan, was constructed in the Jordan valley area in the year 1979. Currently, the dam holds about 72% of its designed storage capacity with total dissolved solids concentration of 2.2%. The dam water was designed to irrigate 100 km2 of new reclaimed areas and to provide drinking water for more than 30,000 residences. In this work, solar desalination system
Studies of societal exergy use have the common aim of tracing the flow of exergy along society, and are used to gain insights into the efficiency of energy use and linkages to economic growth. However, their methodological approaches vary greatly, with significant impacts on results. Therefore, we make a review of past studies to identify, synthesize and discuss methodological differences, to cont
In pump-probe experiments employing a free-electron laser (FEL) in combination with a synchronized optical femtosecond laser, the arrival-time jitter between the FEL pulse and the optical laser pulse often severely limits the temporal resolution that can be achieved. Here, we present a pump-probe experiment on the UV-induced dissociation of 2,6-difluoroiodobenzene (C6H3F2I) molecules performed at
Fontan palliation patients are at risk for ventricular arrhythmias post-operatively. This study aimed to evaluate whether differences in the spatial QRS-T angle can reliably predict ventricular arrhythmias in patients who had undergone Fontan palliation. A total of 117 patients who had the Fontan palliation and post-Fontan catheterization were included. Ventricular arrhythmias were identified in n
Controlling robots in real-time over a wireless inter- face present fundamental challenges for forthcoming fifth gen- eration wireless networks. Mission critical real-time applications such as telesurgery over the tactile Internet require a commu- nication link that is both ultra-reliable and low-latency, and that simultaneously serving multiple devices and applications. Wireless performance requi
The paper presents the control server, a real-time scheduling mechanism tailored to control and signal processing applications. A control server creates the abstraction of a control task with a specified period and a fixed input-output latency shorter than the period. Individual tasks can be combined into more complex components without loss of their individual guaranteed fixed-latency properties.
The hydrogen bond (H bond) is one of the most important interactions that form the foundation of secondary and tertiary protein structure. Beyond holding protein structures together, H bonds are also intimately involved in solvent coordination, ligand binding, and enzyme catalysis. The H bond by definition involves the light atom, H, and it is very difficult to study directly, especially with X-ra
Many succinate:quinone oxidoreductases in bacteria and mitochondria, i.e, succinate:quinone reductases and fumarate reductases, contain in the membrane anchor a cytochrome b whose structure and function is poorly understood, Based on biochemical data and polypeptide sequence information, we show that the anchors in different organisms are related despite an apparent diversity in polypeptide and he
It is well known that Franz Liszt was fond of the harp as an instrument, and his use of the harp in the orchestra is innovative. He also befriended and worked with prominent harpists of his time, such as Elias Parish-Alvars, Wilhelm Posse, Jeanne Pohl and Rosalie Spohr. The transcriptions he once made for harp are now lost. However, a recent finding in a collec- tion in a Swedish museum, Murberget
A high resolution soft X-ray monochromator for the 550 MeV MAX storage ring is described. The instrument combines a plane elliptical premirror collecting a large (10 mrad) horizontal angle of radiation and a modified version of the well-known SX-700 plane grating monochromator (PGM). The modification consists of changing the original ellipsoidal focussing mirror to a plane elliptical mirror. There
Oats are an excellent source of high-quality proteins, with a favourable amino acid composition. Oat proteins therefore have greatpotential to complement existing animal and plant protein sources, especially if the protein content could be increased. In this thesis,high-protein oat lines were identified and characterised. More than a thousand individual lines in a mutagenised oat population(Target
