Sexual conflict over mating has been documented in many species, both in the field and in experimental studies. In pond damselflies (family Coenagrionidae), sexual conflict maintains female-limited color polymorphisms, with one female morph typically being a male mimic. However, it is not known whether sexual conflict can also explain the evolutionary origin of novel female morphs, and if so, what

Developing novel organic photovoltaic materials for organic solar cells (OSCs) requires precise characterization of their charge transfer states to optimize the photoinduced charge transfer mechanisms within the photoactive layer. The microscopic photoelectric properties of the S-shaped (DYA-I-S) and O-shaped (DYA-I-O) conformations of dimeric small molecule acceptors (DSMAs) are analyzed through

A pervasive dilemma in brain-wide association studies1 (BWAS) is whether to prioritize functional magnetic resonance imaging (fMRI) scan time or sample size. We derive a theoretical model showing that individual-level phenotypic prediction accuracy increases with sample size and total scan duration (sample size × scan time per participant). The model explains empirical prediction accuracies well a

2-amino-2-methyl-1-propanol (AMP) in dimethyl sulfoxide (DMSO) is a precipitating non-aqueous amine technology that can potentially lower the energy demand during CO2 removal from industrial flue gases compared to aqueous amine technologies. However, DMSO is hygroscopic and has a high possibility of absorbing water from humid flue gases, which can affect the physical properties of the system,

Overweight and obesity rates have increased in recent decades, particularly among the younger population. The long-term consequences of obesity with respect to early venous thromboembolism (VTE) in women have not been established. The aim was to investigate the association between body mass index (BMI) in early pregnancy as a proxy for non-pregnant weight and long-term post-pregnancy risk of VTE i

ABSTRACTObjectivesAn emerging body of research reveals a heightened risk of gambling problems among elite athletes, particularly among males, but these studies often suffer from small sample sizes and lack diverse representation across sports and groups. This study aimed to investigate gambling problems and their correlates among elite male and female ice hockey players in Sweden’s top leagues.Met

The Andes mountains extend north–south in a latitudinal gradient of 8500 km. Because of the great climatic variety and the peculiar north–south orographic distribution, lakes are highly diverse, including different lake origins and contrasting morphometries. We reviewed >700 ecological studies on Andean lakes to identify the main threats to these freshwater systems. The most important threats are

Background: Since its inception in 1980, the MOHL index (% patients who are male, have occupational, hand, or leg dermatitis, respectively) and its later evolutions until the presently used MOAHLFA(P) index (adding % patients with atopic dermatitis, face dermatitis, age 40+ years and positive reaction(s) to ≥ 1 baseline series allergen) have been intended to convey important demographic and clinic

Who conducts biological research, where they do it and how results are disseminated vary among geographies and identities. Identifying and documenting these forms of bias by research communities is a critical step towards addressing them. We documented perceived and observed biases in movement ecology, a rapidly expanding sub-discipline of biology, which is strongly underpinned by fieldwork and te

Protozoan parasites of the genus Leishmania cause leishmaniasis, a disease with variable clinical manifestations that affects millions of people worldwide. Infection with L. donovani can result in fatal visceral disease. In Panama, Colombia, and Costa Rica, L. panamensis is responsible for most of the reported cases of cutaneous and mucocutaneous leishmaniasis. Studying a large number of drug cand

Objectives Investigating men's perceived lifetime risk of prostate cancer. Design Survey-based study to men invited for prostate-specific antigen (PSA) screening in the GÖTEBORG-2 trial between September 2015 and June 2020. Setting 38 775 men in the Gothenburg area, Sweden, were invited for PSA-Testing and participated in a survey. Participants 17 980 men participated in PSA-Testing, of whom 13 18

We studied the neural and hormonal regulation of the secretion of pancreatic spasmolytic polypeptide (PSP), a potential growth factor, from isolated perfused porcine pancreas and the pancreatic exocrine secretion of PSP in response to a meal in young conscious pigs. PSP concentrations in the pancreatic juice ranged from 1 to 180 μg/ml. PSP released to the venous effluent amounted to 0.4-7% of the

Following the Paris Agreement's climate targets and the modelling community's scenarios of how to reach them, carbon dioxide removal is gaining increasing importance in national climate policies. This is also the case in Denmark – considered by itself and others a climate frontrunner – where biochar is envisioned to cover 10% of the 2030 reduction goal. However, apart from research experiments and

The average life expectancy for large companies on the fortune 500 list has declined rapidly since the 1950s. One major reason is the growing competition from new actors on the market. Innovation has become one of the most important competencies for companies to get ahead of the competition. The growing demand for companies to be innovative and at the same time operate their core business have dee

We aim to reinforce the importance of more qualitative empirical studies researching the particularities of co-creation efforts, in the context of new, ambiguous mutations of work and organization generated by internet technologies. While answering our research question we will look into personal accounts referring to the individual’s experience of volunteering for Mozilla, and we will contribute

Many houses of the “miljonprogrammet” is now facing a major improvement need, and not least in terms of energy improvement, Drottninghög in Helsingborg is one such area. It is a houses from Drottninghög that is used as an example in this report. The energy improvements addressed in this report is mainly concerning construction improvements. The building from Drottninghög is poorly insulated whit t

Wood density is a crucial trait in trees influencing carbon storage in forests, yet dynamic global vegetation models (DGVMs) neglect its variability under different environmental conditions. For this thesis, I integrated environmentally-dependent wood density into the DGVM LPJ-GUESS by simulating mean annual tree ring density based on temperature variables. The model considers earlywood and latewo
