A new environmental transmission electron microscope has been installed in Lund in order to investigate the growth of III-V semiconductor nanowires by metal-organic chemical vapour deposition. We report here on the concepts behind the design of the facility and on details of the operation, and we refer to early results to highlight the new information that can be accessed from in situ studies. The
We know that informal networks explain differences in career success. Historical differences in business careers of men and women have frequently been explained with differences in informal networks. We also know that corporations tend to recruit future leaders and professionals from highly ranked business schools, and that important social networks form among the students there. However, it is no
An acoustofluidic device, consisting of a polymer chip with a long straight channel, coupled to a piezoelectric transducer is modeled numerically in three dimensions and compared to experimental results in terms of the electric admittance as well as the ability to focus particles. In our experiments we obtain good acoustic particle focusing at a frequency of f = 1.14 MHz with an actuation voltage
The article outlines the most pressing justice questions in a transition to a fossil fuel-free welfare state in Sweden.
We demonstrate that exceptional points exist in fully transparent, optically "effectively" biaxial, anisotropic micro-cavities, fabricated using an uniaxial cavity material with its axis inclined to the Bragg mirror growth direction. This is similar to the existence of singular (optic) axes in absorbing biaxial crystals, but the lack of time reversal symmetry is mediated by the mode broadening, i.
This article presents the developments of an ongoing research aimed at modelling the influence of fissuring on the behaviour of clays. In particular, it recalls the main results of an extensive laboratory investigation on a fissured bentonite clay from the south of Italy and presents the data of a new investigation on the evolution with shearing of the strain fields developing within the clay, res
Airway basal cells are crucial for regeneration of the human lung airway epithelium, and are thought to be important contributors to Chronic Obstructive Pulmonary Disease (COPD) and other lung disorders. In order to reveal how basal cells contribute to disease, and to discover novel therapeutic targets, these basal cells need to be further characterized. In this study, we optimized a flow cytometr
Mohsen Rezaee, a high-ranking official of the Islamic Republic in Iran, has admitted that top-secret Iranian nuclear documents were stolen in a raid of a Tehran warehouse by Israeli operatives in 2018—a raid the regime had denied ever occurred. Rezaee is calling for a purge of the Iranian intelligence and counterintelligence community, which could result in Iranian intelligence operatives fleeing
Epidemics and pandemics are associated with a variety of life-threatening conditions and have serious effects on physical as well as mental wellbeing. The Covid-19 pandemic raised the same difficulties for public and private sectors including schools, businesses, healthcare sectors, etc. The disease, which originated in Wuhan, China in December 2019, has ravaged nearly every country in the world.
The use of protective gloves is of importance in workplaces where hazardous chemicals are handled, including the chemical industry, the plastic industry, as well as in environments such as dental practices, hairdressing, and beauty salons. Occupational dermatology can provide crucial advice regarding how to avoid or protect the patient against allergens found in the work environment and provide th
Aims: Since its outbreak in 2020, the COVID-19 pandemic has directly caused the premature death of millions. However, indirect consequences, such as social restrictions, have affected a far greater number. We explored the association between the spread of COVID-19 and end-of-life circumstances in the infected and non-infected population in Sweden. Methods: In this descriptive, population-based, ob
Remote sensing data has been proven capable and efficient as a powerful resource for large-scale land cover mapping. However, a map is considered acceptable with the required accuracy value. The problem related to sampling is how the sample amount and sample technique affect the accuracy of the land cover mapping. Furthermore, the accuracy assessment for mapping usually only utilizes accuracy meas
Background: Diagnosing internal herniation (IH) in Roux-en-Y gastric bypass (RYGB) patients with acute abdominal pain poses a diagnostic challenge. Diagnostic laparoscopy is often required for a definitive diagnosis. We hypothesized that intestinal ischemia biomarkers would aid in the diagnosing of IH. Objectives: To explore intestinal ischemia biomarkers in diagnosing IH. Setting: University Hosp
Artikeln behandlar typografins roll i relationen mellan text och läsare med utgångspunkt i bland annat bibliografisk teori och Jean-Luc Nancys fenomenologiska tankar om skrift och läsande. I fokus för artikeln står frågan: Kan vi förstå boken med sin typograferade text som litteraturens kropp? In one of his fragments, Georg Christoph Lichtenberg explains that German books printed with roman type, instead of the then default gothic type, always give him a feeling that he needs to translate them – evidence, he says, of “the degree to which our concepts are dependent on these signs”. The article elaborates on this thought. It explores the relation between literature, text (abstract and mat
