Improved characterization of the TOI-2141 system: A dense sub-Neptune with non-transiting inner and outer companions

Aims. We aim to refine the fundamental parameters of the TOI-2141 planetary system, which includes a transiting sub-Neptune orbiting a Sun-like star on a relatively long orbit of 18.26 days, by combining new photometric and spectroscopic observations. Methods. We analyzed new space-based photometry from TESS and CHEOPS, as well as 61 radial velocity measurements from HARPS-N. We performed individu

Religion and Indigenous Worldviews in Climate Change Adaptation – A Scoping Review

This thesis presents a scoping review of academic literature on the intersection of religion, spirituality, and Indigenous worldviews with climate change adaptation. While adaptation research has traditionally emphasised technical, institutional, and financial dimensions, the cultural and spiritual dimensions shaping community responses remain underexplored. To address this gap, the review systema

Multiplicity-dependent jet modification from di-hadron correlations in pp collisions at √s = 13 TeV

Short-range correlations between charged particles are studied via two-particle angular correlations in pp collisions at √s = 13 TeV. The correlation functions are measured as a function of the relative azimuthal angle ∆φ and the pseudorapidity separation ∆η for pairs of primary charged particles within the pseudorapidity interval |η| < 0.9 and the transverse-momentum range 1 < pT< 8 GeV/c. Near-s

Light neutral-meson production in pp collisions at √s = 13 TeV

The momentum-differential invariant cross sections of π0 and η mesons are reported for pp collisions at = 13 TeV at midrapidity (|y| < 0.8). The measurement is performed in a broad transverse-momentum range of 0.2 < pT< 200 GeV/c and 0.4 < pT< 60 GeV/c for the π0 and η, respectively, extending the pT coverage of previous measurements. Transverse-mass-scaling violation of up to 60% at low transvers

Quality of Life and Economic Burden in Swedish Adults with Atopic Dermatitis : A Cross-sectional Survey of Patientreported Outcomes

Atopic dermatitis (AD) is a chronic skin disease associated with impaired quality of life. Evidence from Sweden on out-of-pocket expenses and productivity losses remains limited. This study assessed the burden of AD among adults in relation to health-related quality of life (HRQoL), work productivity, activity impairment, willingness to pay for symptom relief, economic outcomes, considering comorb

Advancement flaps in perianal fistulizing Crohn’s disease: technical steps and current evidence

Fistulizing perianal Crohn’s disease is complex and negatively affects quality of life. Rectal advancement flap (AF) has been widely adopted as a sphincter-preserving procedure for treating complex anal fistulas. The European Crohn’s and Colitis Organisation (ECCO) guidelines on surgical treatment of Crohn’s disease state that AF is a therapeutic option for patients with Crohn’s disease and comple

Using an abstract geometry in virtual reality to explore choice behaviour: visual flicker preferences in honeybees

Closed-loop paradigms provide an effective approach to studying visual choice behaviour and attention in small animals. Different flying and walking paradigms have been developed to investigate behavioural and neuronal responses to competing stimuli in insects such as bees and flies. However, the variety of stimulus choices that can be presented over one experiment is often limited. Current choice

Glycoprotein 340 and sialic acid in minor-gland and whole saliva of children, adolescents, and adults.

Glycoprotein 340 (gp-340) is a bacterial-binding glycoprotein found in major-gland and minor-gland saliva. Sialic acid, a common terminal structure of salivary glycoproteins, interacts with microorganisms and host ligands, as well as with free radicals. This study investigated the contents of gp-340 and sialic acid in minor-gland saliva and whole saliva of children (3 yr of age), adolescents (14 y

Incidence of airflow limitation in subjects 65-100 years of age.

The true incidence of chronic obstructive pulmonary disease is largely unknown, because the few longitudinal studies performed have used diagnostic criteria no longer recommended by either the European Respiratory Society or the American Thoracic Society (ATS).We studied the incidence and significance of airflow limitation in a population-based geriatric sample using both an age-dependent predicte

Time-resolved NIR/Vis spectroscopy for analysis of solids: Pharmaceutical tablets

Time-resolved spectroscopy in the visible and near-infrared (NIR) regions was used in a feasibility study for analysis of solid pharmaceuticals. The objective of the experiments was to study the interaction of light with pharmaceutical solids and to investigate the usefulness of the method as an analytical toot for spectroscopic analysis. In these experiments, a pulsed Ti:sapphire laser and white

Att stå mellan två världar - En kvalitativ studie om identitetsskapandet hos andra generationens invandrare

This study seeks to explore the identity and cultural belonging of second-generation immigrants. The purpose is to examine the view that second-generation immigrants have on these two aspects and the impact it has on creating their identity. The study is conducted through qualitative semi-structured interviews held with six individuals who qualify as second-generation immigrants. The individuals c

Nedmonteringen av försvaret på Gotland - En analys av beslutet att avveckla Regemente P 18 under 2004

This study demonstrates how political decisions are contextually bounded by prevailing perceptions of reality. Even strategic choices tend to be shaped more by recent events than by long-term analysis. Gotland, located in the middle of the Baltic Sea, is today considered a key strategic area for NATO. Historically, the island has played an important military role, and this study examines its conte

Legitimizing ESS Legitimizing ESS: Big Science as collaboration across boundaries The ESS theme at the Pufendorf Institute The purpose of this theme is to study the European Spallation Source (ESS) to be inaugurated in Lund 2019. We will apply perspectives from economics, the social sciences and the humanities to analyze ESS as a contemporary Big-Science facility focusing on processes of legitimat

Spectral Tuning, Stabilities under External Exposures, and Spontaneous Enhancement of Emission Intensity in Grown-into-Glass All-Inorganic Metal Halide Perovskite Nanocrystals

Herein, the grown-into-glass (GIG) CsPbBr3:Ln3+ (Ln = La, Lu) nanocrystals (NCs) are designed and fabricated using an in situ nanocrystallization method. It is shown that a substitution of Pb2+ sites with Ln3+ ions leads to a blueshift of emission position induced by an increase of the bandgap of CsPbBr3. Additionally, the GIG-samples are found to feature excellent photoluminescent (PL) properties

Groundhog Day at the 2024 United Nations biodiversity conference : What COP 16 can teach us for reforming environmental summits

With 23,000 registered participants and unprecedented media attention, the 16th conference of the parties (COP) to the United Nations Convention on Biological Diversity (CBD) in Cali, Colombia, was the largest in the 32-year history of these biannual meetings. In terms of successes, the Cali conference established a new subsidiary body to protect concerns of indigenous communities and local popula
