Only 40% of the total CO2 emitted by human activities and natural sources remain in the atmosphere, since the rest is taken up by plants and oceans. In particular temperate and boreal forests are usually significant sinks of carbon, even if they are very susceptible ecosystems and they might turn into sources in consequence of the predicted temperature increase. That is one of the reasons why a ne
The purpose of this essay was to further develop the discussion around the street-level bureaucrats and the dilemmas that they meet in their work environment. The paper will try to accomplish this by putting the spotlight on the professional role, the organizational control of the street-level bureaucrat and the effect of society on the work environment. Something that also will be discussed is th
The Economic Dispatch Problem (EDP) plays a critical role in power system operations by trying to allocate power generation across multiple units at minimal cost while satisfying complex operational constraints. Traditional optimization techniques struggle with the non-convexities introduced by factors such as valve-point effects, prohibited operating zones, and spinning reserve requirements. Whil
There has been great interest in the rationales for transformative innovation policies (TIP), including those following a mission-oriented logic. However, few studies have investigated how public administration can effectively implement TIP. To study this, we first identify from existing literature four TIP governance tasks (creating legitimacy and leadership, coordination across levels/instrument
The current paper focuses on the conceptual design and numerical analysis of a four-stage centrifugal pump for the fuel system of a turbofan engine with liquid hydrogen as fuel. Liquid hydrogen is challenging at high pressures due to its special fluid properties. The design condition for the pump is set at take-off, to raise the pressure of liquid hydrogen from 6 bars at the outlet of a low-pressu
Among the many approaches to improve the performance of lithium-metal batteries, ternary polyethylene oxide/ionic liquid/lithium salt electrolytes offer several advantages such as low flammability, high conductivity (vs. polyethylene oxide/lithium salt electrolytes) and, to a large extent, limiting the growth of dendrites at moderate currents. However, they suffer from relatively low mechani
Hydrochlorothiazide has been associated with increased cutaneous squamous cell carcinoma risk. Meanwhile, its association with basal cell carcinoma (BCC) risk is controversial. The association between commonly prescribed antihypertensive medications and BCC risk in the Swedish population was investigated. All cases with a histopathologically verified BCC in Sweden during 2007–2017 and 2 matched co
Background: Pain in children is undertreated. An assessment scale co-designed with children, parents, and health care professionals could lead to more effective pain assessments and treatment strategies aimed at reducing pain and pain-related symptoms. There are analogue scales validated for self-report of pain in children, but today, children regularly use digital technology, which healthcare sho
Introduction: Amyloid- and tau-positron emission tomography (PET) are promising modalities for detecting pathological changes associated with Alzheimer’s disease (AD); however, their application is limited. Although the use of cerebrospinal fluid (CSF) biomarkers as alternatives to amyloid-PET and tau-PET has been explored, no in vitro diagnostic-approved or commercial CSF biomarker assays are cur
Currently, the European Union (EU) is the “green leader”, globally, in adopting policies to support longer product lifetimes. One reason for this state of affairs is that EU Member States are adopting progressive policies, which put pressure on the EU to set EU-wide laws to replace national ones. The main reason for this situation is that national rules may lead to distortions in trade in the EU S
Context. Strongly lensed quasars are fundamental sources for cosmology. The Gaia space mission covers the entire sky with the unprecedented resolution of 0.18âà € ³ in the optical, making it an ideal instrument to search for gravitational lenses down to the limiting magnitude of 21. Nevertheless, the previous Gaia Data Releases are known to be incomplete for small angular separations such as thos
Improving accuracy and timeliness for osteoporosis diagnosis could help prevent fragility fractures, morbidity, and mortality for older individuals. Osteoporosis is an often silent health condition, especially as regards vertebral fractures, and WHO issued a call to action for primary care to lead efforts in screening, assessing, and managing diseases such as osteoporosis. We used a machine learni
This study is evaluating two methods in order to calculate predicted no effect concentrations (PNECs) used in environmental risk assessment for three chemicals (α-Amylcinnamaldehyde, 1-tridecanol and paracetamol). The methods used are Species Sensitivity Distributions (SSD) and the guideline from European Chemicals Agency (ECHA): “Guidance on information requirements and chemical safety assessment
Lumazine Synthase forms pentamers, C5 in some organism and icodahedra, Ih in other. The aim of this project is to investigate which evolutionary steps could have led the pentamers to assembly into icosahedral capsids. Therefore prevoius work has been performed to reconstruct ancestral sequences for the pentameric and icosahedral forms of Lumazine Synthase. The icosahedral sequence had been express
To allow further device scalability within the data storage industry there needs to be continued research of new technologies. One promising technology is the Magnetic Random Access Memory (MRAM), based on magnetoresistive elements, which is non-volatile; consume low power and have fast read and write operations. To make the technology scalable, the bit (the smallest element in the MRAM) needs to
Denaturation mapping is a powerful and fast method for optically analyzing DNA molecules.It can be used to characterize DNA molecules on a scale of a few hundred base pairs which is sufficient for applications. Denaturation mapping requires a sufficiently high optical resolution of the imaging system used, which typically translates to an expensive, bulky microscope. For point-of-care testing or u
This work presents the design for a temperature drift-free path imbalanced ber interferometer for long-term laser frequency stabilization using coated bers with different thermal drift. For this purpose, single acrylate, dual acrylate, copper and aluminum coated bers are analyzed theoretically and experimentally regarding the thermal sensitivity of their optical path length. Experimental results w
The field of particle physics is ever evolving. With the recent advent of the Large Hadron Collider (LHC) it is possible that the long sought for Higgs boson is detected. While this is not certain even if it is found it is likely that it will need more precise methods of investigation. For this and other reasons, a new collider called the International Linear Collider (ILC) is being planned. This
