Affordable and competitive industrial automation is of key importance for small and medium enterprises, in Europe and elsewhere. A key factor is the introduction of new robot automation concepts that ease fast deployment and extend available task repertoire. The Gantry-Tau manipulator is a new robot concept. In contrast to other parallel kinematic manipulators (PKMs), it has a large working range.
Populärvetenskaplig sammanfattning: Frågan om jordens ålder fick sitt svar först vid 1900-talets början, då upptäckten gjordes att uran sönderfaller till bly med bestämd hastighet. Genom att mäta blyisotoper i uranhaltiga mineral kunde man räkna baklänges och se hur lång tid som krävts för att den uppmätta mängden bly skulle bildas. Samma typ av beräkningar gjorda på mineralet zirkon (ZrSiO2) är iZircon crystals from mafic intrusive rocks and surrounding gneisses were studied using back-scattered electron and cathodoluminescence imaging and laser ablation ICPMS. The rocks are exposed on the island of Norra Horten northwest of Varberg off the western coast of Sweden. The intrusion is mainly made up of amphibolite and metadiorite. Most zircons in the mafic rocks have prismatic external morph
Problem definition: In the Swedish construction projects, there is a role "logistics manager" whose assignment is to manage the logistics at the production site. Exactly how and which logistic related tasks they perform is uncertain. The study’s aim is to find some general patterns and methods that are used by the role holders.
Purpose: The study aims to contribute to t
Populärvetenskaplig sammanfattning: I Bellinga stenbrott, beläget på Romeleåsens sydöstra del i Skåne, har torv hittats. Torven var täckt av morän som den senaste istiden lämnade efter sig. Kol-14-datering användes för att bestämma torvens ålder. Det finns en begränsning i hur gammalt ett organiskt material kan vara för att kunna dateras och därför kunde kol-14-dateringsanalysen endast säga att toIn the Bellinga quarry, located on the southeastern part of the horst Romeleåsen in Scania, southern Sweden, a sub-till organic deposit has been discovered. 14C-dating gave the deposit an age of > 48 000 BP. This means that the deposit could have been deposited either during the Wechselian glacial, the Eemian interglacial or even earlier. A pollen analysis and a macrofossil analysis were performed

Populärvetenskaplig sammanfattning: I det svenska landskapet saknas många av de naturliga våtmarker som fanns innan våtmarkerna dränerades för att göra plats till åkermark. Idag försöker man rekonstruera eller anlägga helt nya våtmarker i Sverige då främst i odlingslandskapet. Detta görs inte enbart för att ge tillbaka en del av det naturliga landskapet och öka den biologiska mångfalden, våtmarkerWetlands are constructed for uptake of nutrients in areas that have exceeded critical loads of nitrogen and also for promoting biological diversity. Wetlands have not only positive effects, they have some negative environmental effects as they emit the greenhouse gases methane (CH4), carbon dioxide (CO2) and nitrous oxide (N2O). There are different ways to construc
The Tibetan Plateau is the highest and largest plateau in the world, hosting unique alpine grassland and having a much higher snow cover than any other region at the same latitude, thus representing a “climate change hot-spot”. Land surface phenology characterizes the timing of vegetation seasonality at the per-pixel level using remote sensing systems. The impact of seasonal snow cover variations
Safety performance functions are frequently used to describe the relation of various factors to the number of accidents, often focusing on exposure of vulnerable road users. Those studies require reliable data regarding exposure, but collecting such data is resource demanding, often resulting in short observational periods. This might produce measurement errors, influencing the reliability of the
Two major debates frame Arctic prehistory: the emergence of specialized maritime economies that support sedentism and growing socio-political complexity, and the role of these economies in the transition from Paleo-Inuit to Neo-Inuit traditions. This shift, originating in the Bering Strait, led to Thule Inuit dispersal across the Arctic, impacting Indigenous communities today. However, understandi
This study reports the synthesis and characterization of heterogeneous acid catalysts derived from rice husk biochar, modified by sulfonation and Ce(NO3)3·6H2O (cerium (III) nitrate hexahydrate) impregnation, for fatty acid esterification using methyl acetate as a glycerol-free reaction route. The research aims to valorize agricultural residues as renewable and sustainable precursors for solid aci
The Indonesian archipelago, Borneo, Sumatra and West New Guinea (Papua), hosts half of the world's known tropical peat swamps, which support a significant proportion of the estimated biodiversity on Earth. However, several species groups that inhabit peat swamp environments remain poorly characterised and their biology, particularly during early life stages, is not well understood. In the present
Succinate:quinone reductases are membrane-bound enzymes that catalyze electron transfer from succinate to quinone. Some enzymes in vivo reduce ubiquinone (exergonic reaction) whereas others reduce menaquinone (endergonic reaction). The succinate:menaquinone reductases all contain two heme groups in the membrane anchor of the enzyme: a proximal heme (heme b(P)) located close to the negative side of
MXenes are technologically interesting 2D materials that show potential in numerous applications. The properties of the MXenes depend at large extent on the selection of elements that build the 2D MX-layer. Another key parameter for tuning the attractive material properties is the species that terminate the surfaces of the MX-layers. Although being an important parameter, experimental studies on t
Some of the most fundamental chemical building blocks of life on Earth are the metal elements. X-ray absorption spectroscopy (XAS) is an element-specific technique that can analyse the local atomic and electronic structure of, for example, the active sites in catalysts and energy materials and allow the metal sites in biological samples to be identified and understood. A microfluidic device capabl
Seagrass meadows are important ecosystem engineers, providing habitat for a range of marine organisms which sustain many ecosystem functions. Due to global loss of seagrass, conservation and restoration incentives are rapidly increasing. However, it is not well understood how environmental setting affects the structural and functional diversity of macrofaunal communities in eelgrass meadows (Zoste
This paper makes use of nearly 25,000 observations representing over 95,000 paid workdays across over 300 years to investigate individual work patterns, work availability, and the changes in work seasonality over time. This sample is comprised of workers in the construction industry, and includes unskilled men and women as well as skilled building craftsmen – the industry which is often used to es
The study of microbial diversity over time and space is fundamental to the understanding of their ecology and evolution. The underlying processes driving these patterns are not fully resolved but can be studied using population genetic approaches. Here we investigated the population genetic structure of Gonyostomum semen, a bloom-forming phytoplankton species, across two continents. The species ap
We demonstrate detection and measurement of electron paramagnetic spin resonances (EPR) of iron defects in β-Ga2O3 utilizing generalized ellipsometry at frequencies between 110 and 170 GHz. The experiments are performed on an Fe-doped single crystal in a free-beam configuration in reflection at 45∘ and magnetic fields between 3 and 7 T. In contrast with low-field, low-frequency EPR measurements, w
