The movement of bark beetles near an attractive pheromone source is described in terms of mathematical models of the diffusion type. To test the models, two release experiments involving 47,000 marked spruce bark beetles [Ips typographus (L.)] were performed. The attractive source was a pheromone trap, surrounded by eight concentric rings with eight passive trap stations on each ring. Captures wer
Background: Long outdoor stay may cause hazardous exposure to ultraviolet radiation (UVR) from the sun even at high latitudes as in Sweden (Spring to Autumn). On the other hand, long outdoor stay is a strong predictor of primary school children´s free mobility involving moderate to vigorous physical activity (MVPA). UV-protective outdoor environments enable long outdoor stay. We investigated the c
Obestatin is a gastrointestinal peptide having wide-ranging effects on cell proliferation; however, its mechanism of action remains poorly understood. Thus, the aim of the study was to elucidate the effect of exogenous obestatin on the postnatal structural development of the small intestine. Seven-day-old piglets with an average BW of 1.56 ± 0.23 kg were divided into four groups (n = 10) that rece
Background: A previous individual participant data (IPD) meta-analysis showed that the Wells rule and D-dimer testing cannot exclude suspected deep vein thrombosis (DVT) in cancer patients. Objectives: To explore reasons for this reduced diagnostic accuracy and to optimize the diagnostic pathway for cancer patients suspected of DVT. Patients and Methods: Using IPD from 13 studies in patients with
Fertilization is a common approach to increase or sustain soil fertility, but its impact on microbial biomass and community structure remains controversial, particularly in paddy soils. In this study, we investigated the effect of different long-term fertilization strategies, beginning in 1986, namely no fertilization, mineral fertilization, mineral fertilization combined with rice straw or chicke
An optimal network design was carried out to prioritise the installation or refurbishment of greenhouse gas (GHG) monitoring stations around Africa. The network was optimised to reduce the uncertainty in emissions across three of the most important GHGs: CO2, CH4, and N2O. Optimal networks were derived using incremental optimisation of the percentage uncertainty reduction achieved by a Gaussian Ba
Objectives This study aimed to evaluate the image quality of 7 iterative reconstruction (IR) algorithms in comparison to filtered back-projection (FBP) algorithm. Methods An anthropomorphic chest phantom was scanned on 4 computed tomography scanners and reconstructed with FBP and IR algorithms. Image quality of anatomical details - large/medium-sized pulmonary vessels, small pulmonary vessels, tho
The microstructure of cortical bone is key for the tissue's high toughness and strength and efficient toughening mechanisms have been identified at the microscale, for example when propagating cracks interact with the osteonal microstructure. Finite element models have been proposed as suitable tools for analyzing the complex link between the local tissue structure and the fracture resistance of c
Purpose: To assess the performance of a 4-step algorithm for neurological prognostication after cardiac arrest recommended by the European Resuscitation Council (ERC) and the European Society of Intensive Care Medicine (ESICM). Methods: Retrospective descriptive analysis with data from the Target Temperature Management (TTM) Trial. Associations between predicted and actual neurological outcome wer
Background: Interatrial block (IAB) and abnormal P-wave terminal force in lead V1 (PTFV1) are electrocardiographic (ECG) abnormalities that have been shown to be associated with new-onset atrial fibrillation (AF) and death. However, their prognostic importance has not been proven in cardiac resynchronization therapy (CRT) recipients. Objective: To assess if IAB and abnormal PTFV1 are associated wi
Objectives: ACST-2 is currently the largest trial ever conducted to compare carotid artery stenting (CAS) with carotid endarterectomy (CEA) in patients with severe asymptomatic carotid stenosis requiring revascularization. Methods: Patients are entered into ACST-2 when revascularization is felt to be clearly indicated, when CEA and CAS are both possible, but where there is substantial uncertainty
The development of generic pharmaceuticals includes extensive data on equivalence with the reference listed drug is required by the European medicinal agency (EMA) and the North American equivalent. Equivalence must be proven for rheology, microstructure, and performance. This is a costly and time-consuming process. To reduce the costs, it is of interest to investigate if the release profile (perf
Restidsvariation för busstrafiken skapar osäkerhet för både passagerare och operatörer. För resenärer minskar möjligheten att förutse restid och ankomsttid vilket försvårar beslut kopplad till val av avgångstid eller möjligheten till effektiva byten. Operatörerna drabbas av minskad tidtabellstillförlitlighet och ökade kostnader på grund av större marginaler i tidtabellen. Tidigare forskning visar Travel time variability in bus traffic creates uncertainty for both passengers and operators. For passengers, unpredictable travel times complicate trip planning and transfers, while operators face reduced timetable reliability and increased costs from larger schedule buffers. Previous research shows that passengers value reductions in travel time variation more highly than reductions in average t
The aim with this study has been to examine and to analyze the discourse of Rosengård in Swedish media. With the concept of discourse is meant here specific ways to speak about and to understand the world, or a part of it. In order to reach increased understanding regarding media presentations and constructions of Rosengård, I have done a study about how Rosengård has been presented in the Swedish
The Antequera Basin of 150 km2 is a sub-basin to Lake Poopó, located at an altitude of 3800 meters above sea level on the Bolivian high plateau. Lake Poopó is a terminal lake with high salinity and heavy pollution from centuries of extensive mining activity. The climate is semiarid-cold with an average precipitation of 450 mm/year and potential evaporation of 1700 mm/year. Almost all rain falls du
The purpose of this study was to examine what social workers include in the term "parenting ability". More specifically the purpose was to investigate how social workers view the parenting ability among parents with an intellectual disability. Furthermore the aim was to examine what difficulties social workers come across in their work with families where one of the parents are intellect
Introduction: PARP14 is overexpressed and plays an essential role in the survival of many kinds of cancer cells and in inflammatory diseases, and its inhibition could prove to be a future medical treatment. Background: It is still unknown which structures contribute more to PARP14 binding, and because of how conserved the catalytic domain is in the PARP family, the inhibitors need to be selective
Focusing on the norm: A study of social workers’ attitudes towards norms and a norm-critical approach. [translated title] Norms are constantly present in our society and affects us all by narrowing our view of each other and limiting people’s possibilities. Norms concerning social categories such as gender, sexuality, ethnicity and disabilities divide people into different categories based on pre
Rådets direktiv 2001/23/EG om tillnärmning av medlemstaternas lagstiftning om skydd för arbetstagares rättigheter vid överlåtelse av företag, verksamheter eller delar av verksamheter antogs ursprungligen år 1977 som en följd av ökade omstruktureringar och företagsöverlåtelser på den gemensamma marknaden. En viktig bestämmelse återfinns i artikel 3, som stadgar en automatisk övergång från överlåtarThe Council Directive 2001/23/EC on the approximation of the laws of the Member States relating to the safeguarding of employees’ rights in the event of transfers of undertakings, businesses or parts of businesses, was originally adopted in 1977 as a result of an increase in restructurings and transfers of businesses. An important provision is found in article 3, which prescribes the automatic tra
"There's a difference between reading about things and getting into the practical" - teacher students' knowledge and expectations of the mandatory report The Social Services' investigation of child maltreatment and neglect is dependent on information from school teachers.
