Exposure to phenoxyacetic acids and glyphosate as risk factors for non-Hodgkin lymphoma– pooled analysis of three Swedish case-control studies including the sub-type hairy cell leukemia

The association between pesticide exposure and non-Hodgkin lymphoma (NHL) including hairy cell leukemia (HCL) was analyzed in a pooled study of three case-control studies. Results on exposure to pesticides were based on 1,425 cases and 2,157 controls participating in the studies. Exposures were assessed by self-administered questionnaires completed as needed by phone. In the pooled univariate anal

Modelling managed forest ecosystems in Sweden : Poster presentation:

In this work, the forestry-enabled dynamic vegetation model LPJ-GUESS was used to simulate forest standing volume for the three main regions of Sweden. At the regional scale, the model results were evaluated against observational data from the Swedish National Forest Inventory. Carbon fluxes of net ecosystem exchange (NEE), gross primary productivity (GPP), and ecosystem respiration (Reco) were si

Uncertainties surrounding the oldest fossil record of diatoms

Molecular clocks estimate that diatom microalgae, one of Earth’s foremost primary producers, originated near the Triassic–Jurassic boundary (200 Ma), which is close in age to the earliest, generally accepted diatom fossils of the genus Pyxidicula. During an extensive search for Jurassic diatoms from twenty-five sites worldwide, three sites yielded microfossils initially recognized as diatoms. Afte

Properties of the Digital Image

The digital image has become an important carrier of information that supports diagnostics and therapeutics in medicine. Today there are a number of different imaging modalities that each reflects different tissue properties and are based on different technical principles. Together these techniques form a tremendous arsenal for patient diagnostics. Although the underlying physical and technical pr

Handbook of Nuclear Medicine and Molecular Imaging for Physicists : Radiopharmaceuticals and Clinical Applications, Volume III

This state-of-the-art handbook, the third and final in a series that provides medical physicists with a comprehensive overview into the field of nuclear medicine, focuses on highlighting the production and application of radiopharmaceuticals. With this, the book also describes the chemical composition of these compounds, as well as some of the main clinical applications where radiopharmaceuticals

Management of Radioactive Waste in Nuclear Medicine

The use of radionuclides in medicine will inevitably result in various forms of radioactive waste. The waste emerges from the production of radionuclides and radiopharmaceuticals, diagnostic and therapeutic use, and in biomedical research. Radioactive waste can also include spent sealed sources used for calibration, or quality control of different kind of medical equipment. The waste can lie withi

Impact of double cryogelation process on a macroporous dye-affinity hydrogel

Cryogels with interconnected channels allow high flow-through properties and mass transfer when dealing with complex mixtures such as non-clarified crude extracts. However, their mechanical strength can be challenged due to a large void volume inside the polymeric network. We have addressed this problem by forming a double-layer cryogel applied as a dye-affinity chromatography gel. In this study,

Novel inflammatory biomarkers in postural orthostatic tachycardia syndrome

IntroductionPostural Orthostatic Tachycardia Syndrome (POTS) is a disorder characterized by excessive orthostatic tachycardia and orthostatic intolerance. While traditional inflammatory biomarkers tend to be normal, a subclinical inflammatory process may be present in POTS.PurposeWe aimed to analyse novel inflammatory biomarkers in POTS patients: Growth Differentiation Factor 15 (GDF15), Neutrophi

Revisiting the Standard of Proof for Charges of Exceptional Gravity before the International Court of Justice

The International Court of Justice has consistently required a stricter standard of proof for ‘charges of exceptional gravity’. The Bosnia Genocide and Croatia Genocide cases saw the Court require the high standard of ‘fully conclusive’ evidence across all elements of the allegations of genocide. Despite the difficulties associated with obtaining the necessary evidence of the intent of the perpetr

The New CERN Low-energy Facilities for Neutrino Detector Tests

The beamlines at CERN's North and East Areas offer secondary beams in a wide range of momenta between 0.5 GeV/c and 400 GeV/c for fixed-target experiments as well as for test beam campaigns with a flexible configuration and variable beam composition and intensities. Recently, two new facilities for neutrino detectors tests have been established in an extension of the CERN North Area in context of

Size characterisation of noble-metal nano-crystals formed in sapphire by ion irradiation and subsequent thermal annealing

Metallic nano-particles embedded in transparent dielectrics are very important for new technological applications because of their unique optical properties. These properties depend strongly on the size and shape of the nano-particles. In order to achieve the synthesis of metallic nano-particles it has been used the technique of ion implantation. This is a very common technique because it allows

Size-and shape-dependent nonlinear optical response of au nanoparticles embedded in sapphire

Nonlinear optical response of Au metallic nanoparticles, synthesized and embedded in sapphire by using ion implantation, as a function of their size and shape is studied. The size of the Au NPs was varied by controlling the annealing time of the gold-irradiated sapphire in a reducing atmosphere. Their shape was changed from approximately spherical to prolate by swift heavy-ion irradiation using Si

Orientation dependence of swift heavy ion track formation in potassium titanyl phosphate

Potassium titanyl phosphate crystals in both x-cut and z-cut were irradiated with 185 MeV Au ions. The morphology of the resulting ion tracks was investigated using small angle x-ray scattering (SAXS), transmission electron microscopy (TEM), and atomic force microscopy (AFM). SAXS measurements indicate the presence of cylindrical ion tracks with abrupt boundaries and a density contrast of 1 ± 0.5%

Optimal Multitaper Spectrograms

Multitaper spectrograms have been proposed as a method of improving the spectrogram as a time-frequency representation (TFR). This thesis aimed to investigate both previously used and new methods for combining multitaper spectrograms of a Gaussian signal and a chirp. More specifically, the use of new measures to optimize the weights of a weighted sum of spectrograms was tested and evaluated. The o

Gamma Spectrometry

Gamma spectrometry primarily is used for identification and quantification of gamma-emitting radionuclides present in samples collected from a specific environment. The objective is often to determine, with a certain confidence, whether the activity concentration of the present gamma emitters exceed some reference level: for example, a criterion for the highest level of impurity of gamma emitters

The Swedish version of EMPATHIC-30 translation and initial psychometric evaluation

Background: One way to measure quality of care is by measuring satisfaction of provided care among patients and their families. EMpowerment of PArents in THe Intensive Care 30 (EMPATHIC-30) is a self-reported questionnaire grounded on the principles of FCC aiming to measure parents' satisfaction with paediatric intensive care. There is lack of Swedish questionnaires measuring satisfaction with pae

Ukrainian refugee solidarity mobilization online

According to UNHRC, approximately 5 million refugees fled Ukraine between the 24th of February and the 17th of April 2022. Governments and civil societies all over Europe face a major task of mobilizing resources to address the refugees' welfare needs. This effort is partly dependent upon the mobilization of informal civil society. In this research note, we present preliminary findings on the onli
