Purpose: Many centers aim to plan liver transarterial radioembolization (TARE) with dosimetry, even without CT-based attenuation correction (AC), or with unoptimized scatter correction (SC) methods. This work investigates the impact of presence vs absence of such corrections, and limited spatial resolution, on 3D dosimetry for TARE. Methods: Three voxelized phantoms were derived from CT images of
A new product, the surface emissions trap (cTrap), a device developed to stop and bind emissions effectively while having virtually no resistance to water vapor, was installed on a PVC flooring in a school with IAQ complaints. After the installation air concentrations of 2-ethylhexanol decreased rapidly and staff and students reported a considerably improved perceived IAQ. The amounts of 2-ethylhe
This article provides an overview of some of the complex issues involved in reconstructing and visualizing past landscapes. It discusses the importance of empirical data and introduces some of the terminology necessary for understanding methods which are often considered more in the domain of the natural sciences than humanities. Current methods and practices are put in the context of environmenta
Secondary objectives:Secondary objectives:P Primary objective: To assess whether head midline position compared with any other head position is more effective in prevention or extension of germinal matrix-intraventricular hemorrhage in infants born at ≤ 32 weeks' gestational age. Secondary objectives: To perform subgroup analyses regarding gestational age, birth weight, intubated versus not intuba
The prescriptive approach to crisis communication strategy (CCS) selection has long been criticized for lack of flexibility and adaptability. To address this issue, this study proposes an emergent approach to strategy formulation by focusing on contextual impacts on social media crises and their implications for CCS. An online discussion on Sina Weibo, a Chinese microblogging platform, about a hig
Simple models are less input demanding and their calibration involves a lower number of parameters, however their general applicability to vast areas must be tested. We analysed if a simple ecosystem model (PRELES) can be applied to estimate carbon and water fluxes of Boreal forests at regional scale. Multi-site (M-S) and site-specific (S-S) calibrations were compared using evapotranspiration (ET)
Providing sufficient food for a growing global population is one of the fundamental global challenges today. Crop production needs not only to be increased, but also remain stable over the years, in order to limit the vulnerability of producers and consumers to inter-annual weather variability, especially in areas of the world where the food consumed is mainly produced locally (e.g. Sub Saharan Af
Urban green infrastructure (UGI) has been increasingly promoted as a key measure to mitigate heat stress in cities caused by the urban heat island effect and climate change impacts, including climate variability and extremes. However, comparable information concerning the performance of different UGI types to moderate such impacts is mostly lacking. This creates serious challenges for urban planne
Background: Symptoms have been identified as a core outcome domain for atopic eczema (AE) trials. Various instruments exist to measure symptoms in AE, but they vary in quality and there is a lack of standardization between clinical trials. Our objective was to systematically evaluate the quality of the evidence on the measurement properties of AE symptom instruments, thereby informing consensus di
The need for deep decarbonisation in the energy intensive basic materials industry is increasingly recognised. In light of the vast future potential for renewable electricity the implications of electrifying the production of basic materials in the European Union is explored in a what-if thought-experiment. Production of steel, cement, glass, lime, petrochemicals, chlorine and ammonia required 125
Objective To develop and validate ClinESSDAI (Clinical European League Against Rheumatism Sjögren's Syndrome Disease Activity Index), ie, ESSDAI without the biological domain. Patients and methods The 702 fictive vignettes derived from 96 real cases of primary Sjögren's syndrome of the ESSDAI development study were used. As for ESSDAI development, the physician assessment of disease activity (0-10
Vocal learning is a critical behavioral substrate for spoken human language. It is a rare trait found in three distantly related groups of birds-songbirds, hummingbirds, and parrots. These avian groups have remarkably similar systems of cerebral vocal nuclei for the control of learned vocalizations that are not found in their more closely related vocal non-learning relatives. These findings led to
Popular Abstract in Swedish Avinstitutionaliseringen av den psykiatriska vården har medfört att personer med funktionshinder p.g.a. en psykisk sjukdom numera huvudsakligen bor och erbjuds vård ute i samhället. I Sverige har få systematiska studier genomförts som undersöker livssituationen för individer med en allvarlig psykisk sjukdom som bor ute i samhället. Att drabbas av en sjukdom som schizofrThis 18-month follow-up study investigated needs for care and support, quality of life and social network in individuals with schizophrenia or a schizoaffective disorder living in the community and in contact with psychiatric services. The validity of Antonovsky's sense of coherence (SOC) measure was also examined. At baseline 120 patients were interviewed and 94 of these participated in the follo
Popular Abstract in Swedish Allteftersom kraven på kvalité och prestanda hos dagens produkter ökar används alltmer avancerade material som en del av modern produktion. Problemet som uppstår är dock att dessa material ställer nya krav på tillverkningsprocessen och då inte minst vid skärande bearbetning. Trots att en betydande mängd forskning redan har publicerats vad gäller skärande bearbetning av As quality and performance demands on today’s products increases, more and more advanced materials are being used during modern production. The problem is however that this in turn place new demands on the machining processes utilized. Even though a significant amount of research has been published on the machining of these materials knowledge is still limited in several crucial areas. A problem w
Desalination can be a cost-effective way to produce fresh water and possibly electricity. The Gaza Strip has had a complex hydro-political situation for many years. Gaza is bordered by the Mediterranean in the west, by Israel in the north and east and by Egypt in the south. Water and electricity consumption in the Gaza Strip is expected to increase in the future due to the increasing population.
