Over the last 50 years, entrepreneurship as a scientific field has grown significantly - from a small emerging venture in the 1970s to a global industry today with thousands of people around the world who consider themselves entrepreneurship scholars. In this fast growing field there is always a risk that our history will get lost, with consequences in terms of lack of knowledge accumulation and u

Camouflage may promote fitness of given phenotypes in different environments. The tawny owl (Strix aluco) is a color polymorphic species with a gray and brown morph resident in the Western Palearctic. A strong selection pressure against the brown morph during snowy and cold winters has been documented earlier, but the selection mechanisms remain unresolved. Here, we hypothesize that selection favo

Aim: To evaluate the long-term success rate of treatment with the Surgisis® (Biodesign®) anal fistula plug for complex anal fistulas, assess fistula plug failure over time and compare success rates for fistula plug between a group of patients with cryptoglandular fistula and another group with Crohn's fistula. Method: This is a single-centre study of consecutive patients treated with the Surgisis®

The pancreas is particularly sensitive to acute cellular stress, but this has been difficult to evaluate using light microscopy. Pancreatic ischaemia associated with deceased organ donation negatively impacts whole-organ and isolated-islet transplantation outcomes. Post-mortem changes have also hampered accurate interpretation of ante-mortem pancreatic pathology. A rigorous histological scoring sy

Background: Gallbladder cancer (GBC) has a poor prognosis. The aim was to develop and validate a preoperative risk score for incidental gallbladder cancer (IGBC) in patients scheduled for cholecystectomy. Methods: Data registered in the nationwide Swedish Registry for Gallstone Surgery (GallRiks) was analyzed, including the derivation cohort (n = 28915, 2007–2014) and the validation cohort (n = 78

We report thermometry and new Raman linewidth data using a novel method for time-domain rotational coherent anti-Stokes Raman spectroscopy (RCARS) on single-shot basis. The coherences are generated by two fs pulses and probed by a ns pulse. The resulting signal is detected using a combined spectrograph/streak camera setup with high spectral and temporal resolution. Rotational CARS spectrograms of

Despite increasing scientific understanding of the global environmental crisis, we struggle to adopt the policies science suggests would be effective. One of the reasons for that is the lack of inclusive engagement and dialogue among a wide range of different actors. Furthermore, there is a lack of consideration of differences between languages, worldviews and cultures. In this paper, we propose t

Happiness or subjective well-being is often measured by assessing individuals’ judgments of life satisfaction and experience of positive and negative affect (Diener, Psychological Bulletin, 95, 542-575, 1984). In addition, recent research suggests that individuals’ sense of harmony in life is also an important component of subjective well-being (Kjell et al., Social Indicators Research, 126, 893-9

Peoples’ tendencies to be manipulative, opportunistic, selfish, callous, amoral, and self-centered (i.e., an outlook of separateness; Cloninger, Feeling good: The science of well-being, Oxford University Press, 2004; Southern Medical Journal, 100, 740-743, 2007; Mens Sana Monographs, 11, 16-24, 2013) are reflected in individual differences in three dark traits: Machiavellianism, narcissism, and ps

This study is an attempt to improve the loading and release potential of silver oxide nanoparticles (AgO NPs) using Oleic acid based bio-surfactant isolated from Enteromorpha instestinalis. The isolated Oleic acid based bio-surfactant was characterized using GC–MS, NMR, and HPLC. The AgO NPs were then surface-functionalized with the bio-surfactant and analyzed using XRD, HR-TEM/SAED, DLS, UV–Vis,

We present a study of quasi-free-standing monolayer graphene obtained by intercalation of Au atoms at the interface between the carbon buffer layer (Bu-L) and the silicon-terminated face (0001) of 4H-silicon carbide. Au intercalation is achieved by deposition of an atomically thin Au layer on the Bu-L followed by annealing at 850 °C in an argon atmosphere. We explore the intercalation of Au and de

The distribution of the longitudes of solar flares associated with the high-energy proton events called ground level events (GLEs) can be approximated by a Gaussian with a peak at ∼W60, with a full range from ∼E90 to ∼W150. The longitudes of flares associated with the top third (24 of 72) of GLEs in terms of their >430 MeV fluences (F 430) are primarily distributed over E20-W100 with a skew toward

Purpose: Personalized cancer treatment requires predictive biomarkers, including image-based biomarkers. Breast cancer (BC) patients receiving neoadjuvant chemotherapy (NACT) are in a clinically vulnerable situation with the tumor present. This study investigated whether mammographic density (MD), assessed pre-NACT, is predictive of pathological complete response (pCR). Methods: A total of 495 BC

Time perspective has been recognized as an important psychological dimension with a pervasive and powerful influence on human behavior. To the authors’ knowledge, no studies have focused on the relationship between time perspective and cyberbullying behavior. The first aim of this research is to fill this gap by investigating the relationship between different time perspectives and both cyberbully

Differences between individuals in behavioral type (i.e. animal personality) are ecologically and evolutionarily important because they can have significant effects on fitness components such as growth and predation risk. In the present study we are used the invasive round goby (Neogobius melanostomus) from an established population in controlled experiments to examine the relationships among pers

A geometry model for simulating the gas circulation, heat transfer and slab heating process in a reheating furnace was developed with numerical simulation. The slabs are heated in the furnace and the temperature of the slabs become above more than 1500 K, and then they are transported to the rolling mill. The slab heating in a reheating furnace is influenced by many factors, such as gas velocity,

A novel kind of regenerative cooling channel, a so-called nested channel, is proposed to further reduce the combustion chamber wall temperature of a scramjet. The supercritical n-decane heat transfer in the horizontal up-channel and horizontal down-channel with different flow directions are numerically investigated. The temperature distribution, flow field, and vortex structure are presented to di

Titanium dioxide (TiO2) is a unique material for biosensing applications due to its capability of hosting enzymes. For the first time, we show that TiO2 can accumulate reactive oxygen species (ROS) under daylight irradiation and can support the catalytic cycle of horseradish peroxidase (HRP) without the need of H2O2 to be present in the solution. Phenolic compounds, such as hydroquinone (HQ) and 4

Objective: Both psoriatic arthritis (PsA) and rheumatoid arthritis (RA) have a significant impact on quality of life, but few reports have compared the two diseases. The current study assessed health-related quality of life (HRQoL) in PsA at diagnosis and after five years compared with early rheumatoid arthritis (RA) and a matched general population. Methods: Patients with early PsA and early RA i

Alterations in DNA methylation patterns have been associated with many diseases. However, the role of DNA methylation in venous thromboembolism (VTE) is not well established. The aim of this study was to investigate a possible association between global DNA methylation and VTE. The study participants consisted of 168 individuals including 74 patients with primary VTE from the Malmö Thrombophilia S
