Effekter av livsmedelsförädling för lokalkorrosion på rostfritt stål 316L

Pitting corrosion on 316L stainless steel has been widely studied, but knowledge is lacking within food processing environments. A new test setup was developed to enable electrochemical measurements inside a heat exchanger (pasteurizer) where solutions can be heated and cooled rapidly, allowing for corrosion tests of solutions that do not withstand high temperatures for a long period of time. Afte

A Qualitative Systematic Review About Children’s Everyday Lives when a Parent Is Seriously Ill with the Prospect of Imminent Death - Perspectives of Children and Parents

Parental dying is a life changing experience for children. This study explores children’s strategies and (inter)actions in their everyday life when facing critically ill parents and imminent death, from the children’s and parents’ perspectives. A qualitative systematic review was carried out, registered in PROSPERO (CRD42022306862). A literature search and screening in six databases resulted in ei

Sensitivity of CTA to gamma-ray emission from the Perseus galaxy cluster

In these proceedings we summarize the current status of the study of the sensitivity of the Cherenkov Telescope Array (CTA) to detect diffuse gamma-ray emission from the Perseus galaxy cluster. Gamma-ray emission is expected in galaxy clusters both from interactions of cosmic rays (CR) with the intra-cluster medium, or as a product of annihilation or decay of dark matter (DM) particles in case the

Theory, phenomenology, and experimental avenues for dark showers: a Snowmass 2021 report

In this work, we consider the case of a strongly coupled dark/hidden sector, which extends the Standard Model (SM) by adding an additional non-Abelian gauge group. These extensions generally contain matter fields, much like the SM quarks, and gauge fields similar to the SM gluons. We focus on the exploration of such sectors where the dark particles are produced at the LHC through a portal and unde

Advances in carbon dioxide and propylene oxide copolymerization to form poly(propylene carbonate) over heterogeneous catalysts

Chemical conversion of carbon dioxide (CO2) into value-added products is an attractive industrial process because it offers several economic and environmental advantages. This review presents advances and challenges in the CO2 and propylene oxide (PO) co-polymerization using heterogeneous catalysts to form poly (propylene carbonate) (PPC), an environmentally friendly polymer with several applicati

Stability improvement to a ruthenium catalyst for partial oxidation of methane

Catalytic partial oxidation of methane (CPOM) is an energy-efficient alternative to steam reforming, the currently prevailing method for energy production from natural gas. Hulteberg Chemistry & Engineering AB has developed a catalyst for the partial oxidation of methane into syngas, for use in solid oxide fuel cells. In its current form, the catalyst rapidly deactivates, causing increased mat

Understanding and overcoming obstacles in adaptive management

Adaptive management (AM) is widely promoted to improve management of naturalresources, yet its implementation is challenging. We show that obstacles to the implementation of AM are related not only to the AM process per se but also to external factors such as ecosystem properties and governance systems. To overcome obstacles, there is a need to build capacities within the AM process by ensuring ad

Comparable Long-Term Tumor Control for Hypofractionated FLASH Versus Conventional Radiation Therapy in an Immunocompetent Rat Glioma Model

Purpose: To ensure a clinical translation of FLASH radiation therapy (FLASH-RT) for a specific tumor type, studies on tumor control and toxicity within the same biological system are needed. In this study, our objective was to evaluate tumor control and toxicity for hypofractionated FLASH-RT and conventional radiation therapy (CONV-RT) in an immunocompetent rat glioma model. Methods and Materials:

Success factors of global goal-setting for sustainable development : Learning from the Millennium Development Goals

The Millennium Development Goals (MDGs) were an important precursor to the Sustainable Development Goals (SDGs). Hence, identifying the conditions that made the MDGs successful enhances our understanding of global goal-setting and informs the global endeavour to achieve the SDGs. Drawing on a comprehensive review of 316 articles published between 2009 and 2018, we identify six factors that have en

Here Comes the Sun: Imagination, Development, and Technology in Malawi

This paper explores how electrical appliances, together with the idea of attaining energy access in the near future, create hope in a northern village in Malawi. Even though less than one per cent of the rural population has energy access, some of these locals already own solar systems. Nevertheless, their solar equipment is not powerful enough to generate the large amounts of energy required to r

Balancing Cooperation and Resources: A Case Study of Transnational Initiatives in the Cultural Sector

This thesis presents a case study of a Swedish museum’s membership in a European network. Drawing on field material gathered through ethnographic methods, such as interviewing, participant observation and autoethnography, the thesis takes two theoretical perspectives: First, it conceptualizes the network membership as a form of cooperation, following Richard Sennett’s theory on the subject, and se

Coloring mixed QCD/QED evolution

Parton showers are crucial components of high-energy physics calculations. Improving their modelling of QCD is an active research area since shower approximations are stumbling blocks for precision event generators. Naively, the interference between subdominant Standard-Model interactions and QCD can be of similar size to subleading QCD corrections. This article assesses the impact of QCD/QED inte

Serotonin and dopamine transporter availability in social anxiety disorder after combined treatment with escitalopram and cognitive-behavioral therapy

Selective serotonin reuptake inhibitors (SSRIs) and internet-based cognitive behavioral therapy (ICBT) are recommended treatments of social anxiety disorder (SAD), and often combined, but their effects on monoaminergic signaling are not well understood. In this multi-tracer positron emission tomography (PET) study, 24 patients with SAD were randomized to treatment with escitalopram+ICBT or placebo

Characterizing Fast Conformational Exchange of Aromatic Rings Using Residual Dipolar Couplings : Distinguishing Jumplike Flips from Other Exchange Mechanisms

Aromatic ring flips are a hallmark of protein dynamics. They are experimentally studied by NMR spectroscopy, where recent advances have led to improved characterization across a wide range of time scales. Results on different proteins have been interpreted as continuous diffusive ring rotations or jumplike flips, leading to diverging views of the protein interior as being fluidlike or solidlike, r

How scientists interpret and address funding criteria : value creation and undesirable side effects

Scientists and funding bodies are interdependent actors involved in an ongoing two-way signalling interaction; however, we lack insight on the social mechanisms underpinning this interaction. To address this issue, we examine how successfully funded scientists interpret and address criteria set by the funding body to maximise their chances of funding success. We also consider the possible adverse

Induction of Breast Cancer Cell Apoptosis by TRAIL and Smac Mimetics : Involvement of RIP1 and cFLIP

Smac mimetics are a group of compounds able to facilitate cell death in cancer cells. TNF-related apoptosis-inducing ligand (TRAIL) is a death receptor ligand currently explored in combination with Smac mimetics. The molecular mechanisms determining if the combination treatment results in apoptosis are however not fully understood. In this study, we aimed to shed light on these mechanisms in breas

Atmospheric Mercury Concentrations in Guangzhou City, Measured by Spectroscopic Techniques

Atmospheric levels of atomic mercury pollution were measured using spectroscopic techniques in the city of Guangzhou, Guangdong Province, China. Assessments were mainly performed at ground level using a portable (vehicle mounted or hand carried) Zeeman modulation correlation spectrometer (Lumex RA-915M), and the results are given in easily comprehensible diagrams. Measurements were made with conti

ECG Markers of Acute Melatonin Treatment in a Porcine Model of Acute Myocardial Ischemia

In myocardial ischemia, melatonin confers antiarrhythmic action, but its electrocardiographic expression is unclear. We aimed to evaluate the effects of melatonin treatment on electrocardiogram (ECG) parameters reflecting major arrhythmogenic factors and to test the association of these parameters with ventricular fibrillation (VF) incidence. Myocardial ischemia was induced by 40 min coronary arte
