Most modern ultrafast lasers are based on mode-locked fiber or solid-state lasers and operate around the near infrared part of the electromagnetic spectrum. The widely spread CPA based Titanium Sapphire lasers can emit pulses centred around 800nm with durations down to 20 fs. However, for many ultrafast experiments light at different centre frequencies are required. In order to obtain other centre
Traditionellt anses vulkanoklastiska interbeds ha dålig reservoarpotential på grund av de vulkaniska komponenterna, som lätt kan omvandlas till olika lermineral. Publicerade arbeten från interbasaltiska sedimentära avlagringar i Faroe-Shetlands Basin tyder dock på annat. Denna studie syftar därför till att utvärdera porositets- och permeabilitetsegenskaper hos vulkanoklastiska interbeds från FaroeTraditionally, volcaniclastic interbeds have been considered to have poor reservoir potential due to their volcanic components readily altering to various clay minerals, but published discoveries within lava successions in the Faroe-Shetland Basin may challenge this dogma. This study therefore, evaluates porosities and permeabilities for volcaniclastic interbeds from the Faroe Islands Basalt Group
Abstract: The zooplankton community of The Area of Multiple Use Hawaii (AUMH), South Pacific Coast of Guatemala mangrove channel ecosystem was studied in the dry season between February and March 2011. Zooplankton samples were taken during two lunar cycles, four tidal cycles (flood, high water (HW), ebb, low water (LW)), at four different sites. For each sampling occasion, salinity, pH, dissolved
Abstract Estuaries and salt marshes are important wetlands used by waterbirds during winter and migration. However, many salt-marshes have been transformed into salinas, which currently function as high-tide roosts. Since traditional salt production is no longer profitable, many salinas have been abandoned or converted into aquaculture potentially becoming less attractive to waders. In this study
Aim: The aim was to estimate the uncertainty of various factors, influencing the radioiodine uptake (RAIU) at clinical measurements of hyperthyroid patients. Furthermore, to evaluate the estimation of thyroid volume from nuclear medicine scintigraphic images. Another aim was to investigate in what extent these uncertainties may influence the eventual therapeutic radioiodine activity, and thereby t
PFAS (per- and polyfluoroalkyl substances) is a large group of pollutants that, over the last decade have been of great academic concern since it has been found all around the globe. PFAS is ubiquitous in our environment and frequently found in low background concentrations in soil and water; recent research has also found that PFAS occur in biotic samples, such as fish and plants. This literature
Background: Blood lipid levels including low-density lipoprotein cholesterol ( LDL-C), high-density lipoprotein cholesterol ( HDL-C), and triglycerides ( TG) are highly heritable. Genome-wide association is a promising approach to map genetic loci related to these heritable phenotypes. Methods: In 1087 Framingham Heart Study Offspring cohort participants ( mean age 47 years, 52% women), we conduct
Popular science summary: Is RpS6 activation important for leukemia cell progression? Acute Myeloid Leukemia (AML) is the most common acute blood cancer in adults. It is characterized by a rapid increase of leukemic cells in the bone marrow, compromising the development of new blood cells. Despite improvement in treatments and advancements in supportive care, the overall 5-years survival of AML i
Popular science summary: New approaches for treating lakes with ammonia pollution Extract of Yucca shidigera, a desert plant, has been used in aquaculture to control ammonia in the water. Microalgae has been proved effective in removing ammonia and phosphorous from wastewater of agriculture and aquaculture. Therefore, it is possible that they could remove ammonia from lakes. Hence, several fish t
In recent years, different methods for fractionation of native milk fat globules with respect to particle size have been developed. This has been done in order to investigate if the size of the fat globules have any impact on the product functionality. The purpose of this master thesis was to develop a method for fractionation of native milk fat globules with respect to particle size and with focu
In order to reach the climate targets for the society, with significant lower proportions of CO2 emissions than today, certain actions are required. To be able to decrease the emissions, one alternative is to increase the amount of people who uses public transportation as opposed to using cars. The municipality of Åstorp is one of the districts that emits most CO2 per person and day in Scania, and
Northern Fennoscandia belongs to the sub-arctic environment and its forests are mostly composed of mountain birch trees (Betula pubescens ssp. czerepanovii). Outbreaks by autumn moth (Epirrita autumnata) and winter moth (Operophtera brumata) are one of the most important natural disturbance factors in the mountain birch forests, with important implications for future ecosystem functioning. If ther
Recent studies on Alzheimer's disease (AD) suggest that tau proteins spread through the brain following neuronal connections. Several mechanisms could be involved in this process: spreading between brain regions that interact strongly (functional connectivity); through the pattern of anatomical connections (structural connectivity); or simple diffusion. Using magnetoencephalography (MEG), we inves
Importance Adverse pregnancy outcomes are recognized risk enhancers for cardiovascular disease, but the prevalence of subclinical coronary atherosclerosis after these conditions is unknown.Objective To assess associations between history of adverse pregnancy outcomes and coronary artery disease assessed by coronary computed tomography angiography screening.Design, Setting, and Participants Cros
Objective: To describe the clinical and ultrasound characteristics of serous and mucinous cystadenomas in the adnexa. Methods: This was a retrospective international multicenter study. Using the International Ovarian Tumor Analysis (IOTA) database, patients with a histological diagnosis of serous or mucinous cystadenoma who had undergone preoperative ultrasound examination between 1999 and 2016 (I
Poor postoperative outcomes following colon cancer (CC) resection are influenced by multiple factors, including both patient-related characteristics as well as surgeon-related factors. However, the influence of surgical specialization, surgeon resection volume and surgeon gender on patient’s postoperative out- come, after complex procedures such as emergency CC resection, remains incompletely unde
Extracellular vesicles (EVs) are membrane enclosed biological nanoparticles released by cells. In the past two decades, EVs have gained a lot of attention due to their role in numerous biological processes. However, their small nature complicates isolating them from biological fluids with cumbersome techniques, such as ultracentrifugation. Acoustic trapping is a technique that uses ultrasonic stan
Background: Following exposure to traumatic stress, women are twice as likely as men to develop mood disorders. Yet, individual responses to such stress vary, with some people developing stress-induced psychopathologies while others exhibit resilience. The factors influencing sex-related disparities in affective disorders as well as variations in resilience remain unclear; however, emerging eviden
