Background and purpose: Hypofractionated radiotherapy of prostate cancer reduces the overall treatment time but increases the per-fraction beam-on time due to the higher fraction doses. This increased fraction treatment time results in a larger uncertainty of the prostate position. The purpose of this study was to investigate the effect of prostate motion during flattening filter free (FFF) Volume

INTRODUCTION: Poliomyelitis is currently a rare disease in developed countries, where only vaccinal strains seem to be in circulation, which replace wild poliovirus. Nevertheless, it is still a serious disease for children in underdeveloped countries of Asia and Africa.PATIENTS AND METHODS: We analysed nine strains of poliovirus type 2 isolated from the faecal matter of patients with vaccine assoc

Stars formed in clusters can encounter other stars at close distances. In typical open clusters in the Solar neighbourhood containing hundreds or thousands of member stars, 10-20 per cent of Solar-mass member stars are expected to encounter another star at distances closer than 100 au. These close encounters strongly perturb the planetary systems, directly causing ejection of planets or their capt

IntroductionNasopharyngeal cultures are commonly used to determine the causative bacteria in upper airway infections. However, several bacteria can occupy the nasopharynx simultaneously and most healthy children are asymptomatic carriers of presumptive pathogens. This makes the interpretation of nasopharyngeal cultures difficult. Knowledge about which bacteria reside in the nasopharynx can assist

Background: In patients with cardiac resynchronization therapy (CRT), atrial fibrillation (AF) is associated with an unfavorable outcome and may cause loss of biventricular pacing (BivP). An effective delivery of BivP of more than 98% of all ventricular beats has been shown to be a major determinant of CRT-success. Methods: At a Swedish tertiary referral center, data was retrospectively obtained f

Context. Gaia Data Release 2 (DR2) offers unparalleled precision on stars’ parallaxes and proper motions. This allows the prediction of microlensing events for which the lens stars (and any planets they possess) are nearby and may be well studied and characterised. Aims. We identify a number of potential microlensing events that will occur before the year 2035.5, 20 years from the Gaia DR2 refere

Bioethanol has been introduced on a large scale in several countries, for example, in Brazil, the United States, and some European countries such as Sweden. Currently, most bioethanol is produced using starch- or sugar-based production from wheat, corn, or sugar cane (first-generation bioethanol). However, to be able to meet the expected demand, further expansion will have to come from lignocellul

Objective To provide clinical clues to differential diagnosis in patients with chorea and other movement disorders with blood acanthocytes. Methods We present a long-term video accompanied follow-up of six Caucasian patients with neuroacanthocytosis from several centers, three diagnosed with chorea-acanthocytosis (ChAc): 34-y.o.(no.1), 36-y.o.(no.2), 43-y.o.(no.3), two diagnosed with McLeod Syndro

Many modern drugs contain chiral amine moieties and the need for more efficient processes to synthesize these amines in high optical purity and concentration are greatly demanded by the fine chemical and pharma industry. Amine transaminases (ATA) allow for the direct asymmetric synthesis of optically pure amines from ketone substrates. Although academia and industry have been researching ATAs exte

In acts of memorialisation, the objects that ”help” people get into contact with (their memory of) the deceased – like gravestones, personal collections of the deceased’s paraphernalia, objects placed at sites of sudden death, etc. – are often strictly regulated, differently in different cultures. At ”wrong” spots in the urban environment for instance, memorial places can thus be regarded as highl

This paper presents imaging results of measurements conducted at 60 GHz, using the planar rectangular near-field technique. Utilizing the stated techniques at higher frequencies enables detection of smaller defects, and allows for a small measurement set-up in a laboratory environment. An algorithm based on the Fast Fourier Transform (FFT) has been developed in order to process the data. The paper

Despite nearly two decades of disability research highlighting the need to take greater account of disabled people's sexualities, sexuality is still largely a taboo subject in disability services, thus limiting service users’ possibilities to express their sexuality. In this article, I aim to show how Swedish personal assistance managers organize sexual facilitation, that is, assistance from perso

Hybrid-processes combining pervaporation with a conventional separation process to recover organic compounds from waste water has been critically reviewed. Previous research which focused primarily on hydrophobic pervaporation combined with either adsorption, liquid-liquid phase separation, or reverse osmosis showed that these processes offered significant advantages over the exclusive use of just

Growing seal populations are examples of successful marine management, and the seals are often seen as a symbol of a thriving ecosystem. However, seals are well known to interact with local small-scale fisheries by feeding from the gears. This causes both lost catches and broken gear, which negatively affect the economic viability of the small-scale fisheries. While lost catches are known to be su
