Historical documents record the operation of a silver mine from the 16th century AD located near the former village of Salberget in central Sweden. The historical record describes several categories of inhabitants, including local families, workers and miners, foreign engineers and mining specialists, as well as war captives and criminals used as forced labor in the mines. A church yard in the vic

Plants emit large quantities of isoprene and monoterpenes, the main components of global biogenic volatile organic compound (BVOC) emissions. BVOCs have an important impact on the atmospheric composition of methane, and of short-lived radiative forcing agents (e.g. ozone, aerosols etc.). It is therefore necessary to know how isoprene and monoterpene emissions have changed over the past and how fut

The research community of ontological security scholars is vibrant and wide-ranging, defined by a conceptual core and by the themes through which scholars register their disagreements. In this special issue we have collected some of the work that has been produced or inspired by discussions and meetings during the last few years. The goal is to showcase some of the breadth of insights and possibil

(Ga,Mn)As having a wurtzite crystal structure was coherently grown by molecular beam epitaxy on the {1100} side facets of wurtzite (Ga,In)As nanowires and further encapsulated by (Ga,Al)As and low temperature GaAs. For the first time, a truly long-range ferromagnetic magnetic order is observed in non-planar (Ga,Mn)As, which is attributed to a more effective hole confinement in the shell containing

There is growing interest in nanostructures interacting with living organisms. However, there are still no general rules for the design of biocompatible nanodevices. Here, we present a step towards understanding the interactions between nanostructures and living cells. We study the influence of nanomechanical stress induced by zinc oxide (ZnO) nanostructures of different shapes on the viability of

Comprehensive approaches to predict performance of wood products are requested by international standards, and the first attempts have been made in the frame of European research projects. However, there is still an imminent need for a methodology to implement the durability and moisture performance of wood in an engineering design method and performance classification system. The aim of this stud

Between 1991 and 2010, jobs in the knowledge-intensive IT services sector in Sweden increased from 30,000 to 104,000. Departing from recent theoretical insights suggesting that the skill composition of worker inflows is an indicator of knowledge relevant to employers, we investigate labour inflows into the sector. Who were the people getting jobs in this expanding sector? And, how were their skill

We extend the method of rescaled Ward identities of Ameur, Kang, and Makarov to study the distribution of eigenvalues close to a bulk singularity, i.e., a point in the interior of the droplet where the density of the classical equilibrium measure vanishes. We prove results to the effect that a certain “dominant part” of the Taylor expansion determines the microscopic properties near a bulk2 singul

Self-organization in anisotropic colloidal suspensions leads to a fascinating range of crystal and liquid crystal phases induced by shape alone. Simulations predict the phase behaviour of a plethora of shapes while experimental realization often lags behind. Here, we present the experimental phase behaviour of superball particles with a shape in between that of a sphere and a cube. In particular,

The human papillomavirus type 16 (HPV16) life cycle can be divided into an early stage in which the HPV16 genomic DNA is replicated, and a late stage in which the HPV16 structural proteins are synthesized and virions are produced. A strong coupling between the viral life cycle and the differentiation state of the infected cell is highly characteristic of all HPVs. The switch from the HPV16 early g

Surprising weak assembly behavior has lately been found in binary aqueous solvents containing antagonistic salt. The underlying mechanism is still under debate, particularly the role of ion size asymmetry. Here we use small-angle X-ray scattering to study the effect of ion size asymmetry on the mesoscale ordering in a binary solvent composed of water and 2,6-dimethylpyridine with added symmetrical

Purpose - The dimple is adopted into a double wall cooling structure which is widely used in hot gas components to increase the heat transfer effects with relatively low pressure drop penalty. The purpose of this paper is to study the effect of dimple depth and dimple diameter on the target surface heat transfer and the inlet to outlet friction factor. Design/methodology/approach - The study is ca

AZD5423 is a selective glucocorticosteroid receptor modulator developed for the inhaled use in asthma and COPD. This study reports the initial, first-in-man, single and repeat dose-escalating studies in healthy male individuals, including one cohort of male Japanese individuals. Inhaled, nebulized AZD5423 was safe and well tolerated up to and including the highest doses tested for up to 2 weeks of

In this paper, we analyze how to continuously adjust the speed in a supply chain with stochastic demand. For each unit (e.g., truckload, shipping container) in the chain, one must decide at which speed it should be moved downstream, given the state of the system, to minimize total supply chain costs. We decompose the problem into a set of one-dimensional subproblems that can be easily solved and c

Current research investigates automation feedback design compared with a potential design solution that may increase pilot’s situation awareness of the Flight Mode Annunciators (FMAs) to reduce pilot workload and improve human-automation coordination. The research tools include an Eye Tracker and B747 flight simulator. This research evaluated two types of FMAs; a proposed glareshield mounted FMAs

Methanol is today considered a viable green fuel for combustion engines because of its low soot emissions and the possibility of it being produced in a CO2-neutral manner. Methanol as a fuel for combustion engines have attracted interest throughout history and much research was conducted during the oil crisis in the seventies. In the beginning of the eighties the oil prices began to decrease and i

The printed circuit boards basis of electronic equipment have seen a rapid growth in recent years and played a significant role in modern life. Nowadays, the fact that electronic devices upgrade quickly necessitates a proper management of waste printed circuit boards. Non-destructive desoldering of waste printed circuit boards becomes the first and the most crucial step towards recycling electroni
