BACKGROUND: Mean diffusivity (MD) and fractional anisotropy (FA) from diffusion MRI (dMRI) have been associated with cell density and tissue anisotropy across tumors, but it is unknown whether these associations persist at the microscopic level.PURPOSE: To quantify the degree to which cell density and anisotropy, as determined from histology, account for the intra-tumor variability of MD and FA in

Context. Ultra-short-period (USP) planets are defined as planets with orbital periods shorter than one day. This type of planets is rare, highly irradiated, and interesting because their formation history is unknown. Aims. We aim to obtain precise mass and radius measurements to confirm the planetary nature of a USP candidate found by the Transiting Exoplanet Survey Satellite (TESS). These para

Characterization of emissions from fires in a laboratory-controlled environment are presented in this report. The project is initiated by the CERN HSE Unit and is called FIRIA, Fire-Induced Radiological Integrated Assessment. The objective of FIRIA is to enhance the knowledge of aerosols emitted from fires in order to develop dispersion models of radiologically-activated material in case of fire.

In this study, laminar burning velocities (LBV) of ammonia in oxygen-enriched air (oxygen content ranging from 30 to 50 vol%) were investigated under various initial temperatures (298, 323, and 348 K) at a pressure of 1 atm, employing the heat flux method. Our measurements reveal substantial disparities with previously published data primarily obtained using the spherical flame method. The reliabi

BACKGROUND: Alzheimer's disease is characterized by an abnormal increase of phosphorylated tau (pTau) species in the CSF. It has been suggested that emergence of different pTau forms may parallel disease progression. Therefore, targeting multiple specific pTau forms may allow for a deeper understanding of disease evolution and underlying pathophysiology. Current immunoassays measure pTau epitopes

On February 23, 2022, The EU Commission published its Proposal for a Directive of the European Parliament and of the Council on Corporate Sustainability Due Diligence and amending Directive (EU) 2019/1937 (“CSDDD” or “the Proposal”). The purpose of the Proposal, to further the “Union’s transition to a climate-neutral and green economy in line with the European Green Deal and in delivering on the U

Population ageing means that increasingly many are faced with the dual demands of paid work while providing unpaid care to older family members. Caregiving requires time and energy, with implications for paid work and well-being. The challenges faced by individuals add up and therefore also impact national economies. This dissertation provides insights into the implications of unpaid caregiving fo

Background: One of the polymer gel dosimeters available today is the N-isopropylamide (NIPAM) polymer gel dosimeter which has a less toxic monomer compared to other polymer gels and the advantage of being able to be manufactured under normal oxygen levels. Polymer gel dosimeters in general are advantageous independent dosimeters to use for verification of new radiation treatment techniques due to

Can we beat cancer with 3D? In 2020, 19.3 million new cancer cases were reported, and 10 million people died from cancer. Cancer happens because of a mutation in the DNA that leads to uncontrolled cell division, eventually leading to tumors. There is much need for anti-cancer drugs, however, many potential anti-cancer drugs don’t get accepted because of being too toxic or not being good enough. T

The features of social media platforms not only enable the communication between citizens and political actors or institutions, in the form of comments, but also help in magnifying citizens’ voices and opinions and facilitating mass mobilization or political protests. The European Union institutions seem to understand the capacity of social media as a locus for citizen engagement, be it activism o

Salinisation is a global issue which leads to desertification and soil degradation and exposure to salt is also known to inhibit microbial activity and plant growth. This study was conducted to determine the influence of salinity on microbial activity of a non- saline soil. By using Salt Induced Community Tolerance (SICT) concept I found that microbial community tolerance to salt can be induced in

Nuclear power has significantly improved performance over the last thirty years. This improvement has been based on a philosophy of control. That is, for each issue that must be managed to achieve safe performance, a pre-determined barrier must be established. In addition to the barriers that were designed into the plant, a large range of programs, processes and procedures have been developed to d

Suröl är en dryck som ökat i populäritet, speciellt bland folk med stort intresse för hantverksöl och mikrobryggerier. Allt fler bryggerier vågar nu att gå utanför sin trygghetszon med att använda jäst av typen Saccharomyces cerevisiae och istället börjar experimentera med bakterier och jäst som tidigare ansetts vara produktförstörande, till exempel olika mjölksyrabakterier och vildjäst. Genom forSour beer is rapidly gaining popularity among people that have an interest in craft beer and the microbrewing scene. This leads to breweries starting to venture outside their comfort zones regarding the more traditional brewing yeast Saccharomyces cerevisiae and instead have started experimenting with different kinds of bacteria and yeast that in a normal process is regarded as spoilage bacteria,

The European spruce bark beetle is considered as one of the most destructive forest insects to Norway spruce trees in Europe. Climate change may increase the frequency and intensity of bark beetle outbreaks. It is therefore of vital importance to detect the bark beetle outbreaks and take it under control to prevent further damages. Remote sensing techniques may provide a cost-efficient solution to

Title: Adaptation of shipment consolidation and distribution network design to omni-channel retailing Authors: Johan Deniz, Martin Månsson Supervisor: Joakim Kembro, Department of Industrial Management and Logistics, Faculty of Engineering, Lund University Problem description: Global retailers tend to have complex distribution networks. A part of the complexity stems from trade-offs in deciding

Background Transparency of a supply chain is the extent to which all its stakeholders have a shared understanding of, and access to, the product-related information that they request, without loss, noise, delay, and distortion. Having access to accurate and timely information is a challenging issue in global supply chains. Therefore, this research aimed at identifying barriers that could act as

Title: HealthBook Sub title: Integrated End-User Device for Rural Health Workers in Low Resource Settings Author: Johan Larsson Supervisor: Goirgos Nikoleris, Machine Design Secondary supervisor: Rustam Nabiev, Karolinska University, MTA R&D Examiner: Robert Bjärnemo, Machine Design Introduction: This thesis is part of a project called ICT4MPOWER with the purpose to solve the problem with med

Vid en diskussion om nivån på den svenska bolagsskatten är det av stor vikt att avgöra huruvida diskussionen rör den nominella eller den effektiva skattesatsen. Den nominella skattesatsen uppgår till 28 procent och återfinns i 65 kap. 14 § IL. Den effektiva skattesatsen är däremot inte given utan kan i viss utsträckning påverkas, eftersom den bestäms genom att dividera skatt på årets resultat med

The ever increasing data rates in wireless communication require analog to digital converters (ADCs) with greater requirements on speed and accuracy, while being power efficient to prolong battery life. This dissertation contains an introduction to the field and five papers that focus on the continuous-time (CT) Delta-Sigma modulator (DSM) as ADC. Paper I analyses the performance degradation of d
