Traditional robots used in manufacturing are very efficient for solving specific tasks that are repeated many times. The robots are, however, difficult to (re-)configure and (re-)program. This can often only be done by expert robotic programmers, computer vision experts, etc., and it requires additionally lots of time. In this paper we present and use a skill based framework for robotic programmin

Förmågan att uppfatta ljus och vilken riktning det kommer från är utomordentligt användbart för djur. Därför är det inte förvånande att denna förmåga återfinns hos i stort sett varje större djurgrupp, även bland de som anses enkla, såsom koraller och spolmaskar. Endast några få djurgrupper har dock, under evolutionens gång, utvecklat verkligt bra ögon som snabbt kan identifiera objekt av djurens eLight-detection provides incomparabaly rapid information at a range of time scales and, consequently, directional photoreception is found in almost every major metazoan clade. Conversely, a much smaller cohort have evolved sophisticated high resolution vision, which facillitates complex tasks via the detection of fast or small objects,. such as courtship and high-speed pursuit of prey. A few such

Interaction of synthetic TiO2 (anatase) nanoparticles in aqueous suspension at pH 5 was investigated as a function of time in the presence of various organic molecules in terms of adsorption and aggregation behaviour. ζ-potential and average particle diameter were determined with electrophoretic and dynamic light scattering, respectively, while batch adsorption experiments were used to quantify th

The contribution of terrestrially-derived carbon to micro-crustacean zooplankton biomass (i.e. allochthony) has been previously studied in lakes and reservoirs, but little is known about allochthony in rivers. We hypothesized that restricted selective grazing in turbulent environments such as rivers would decouple zooplankton from specific microbial and algal food resources, such that their alloch

Hyponatremia is a severe electrolyte disturbance associated with substantial morbidity and mortality. It often poses a diagnostic and therapeutic challenge. Accurate assessment of patient fluid-volume status is central to effective management. This pilot study aimed to evaluate the usefulness of the Cheetah NICOM bioreactance system and apelin in early differentiation between hypo- and euvolemia i

The literature on sustainable tourism is scant, particularly in the least developed countries. Very few studies touch upon the concept and no holistic theoretical or conceptual frameworks around the idea of sustainable tourism have been formulated. This study aims at exploring the role of tour operators in developing sustainable tourism in Pakistan and how the tour operators (TOs) conceive their r

Background: In the beginning of the COVID-19 pandemic, Swedish authorities enforced specific recommendations on social distancing for adults 70 years and older (70+). Day-to-day life changed for 15% of the Swedish population. The aim of the study was to explore how adults 70+ experienced and managed changes in everyday life due to the COVID-19 pandemic and how those changes affected wellbeing at t

In this paper I address two concerns with Kelly Trogdon’s grounding mechanism view, i.e. the idea that metaphysical explanation can be modeled on causal-mechanical explanation. The first concern threat-ens to undermine the unity that grounding-mechanical explanations imposes on metaphysical explana-tion; and the second concern requires the grounding mechanic to put forth a formal condition on grouIn this paper I address two concerns with Kelly Trogdon’s grounding mechanism view, i.e. the idea that metaphysical explanation can be modeled on causal-mechanical explanation.

During World War II, both Nazi Germany and the Allies invested heavily in propaganda in neutral Sweden. The battle for hearts and minds did not only involve widespread dissemination of propaganda, but Stockholm became a veritable hotspot for espionage as well as intelligence gathering on enemies’ propaganda efforts. Moreover, throughout the war, the Allies used Sweden as a key gateway to circulate

This article discusses a new form of rituals, marketed as coaching or layman therapeutic practices, focusing on self-development and healing, which rapidly expanded in the early 2000s in Sweden. The targets of these rituals are individuals and workplaces, buying these and similar formalized practices. Questions raised include: How do these rituals reflect the structure of society? How are they des

In this chapter the author discusses the difficulties of exploring the ethnography of events as they are happening, especially when they are violent, not least due to the lack of reliable information available and the complex process of interpreting transmissions of affect. The epistemological turn away from language—in which the focus on affect has emerged as a critique of post-structuralism’s in

Global clothing consumption is increasing, with many garments having unnecessarily short lifetimes due to low quality materials and manufacturing, often linked to price pressures. Current European Union strategies focus on improving technical durability, product maintenance, and waste collection, but fail to address the role of the consumer for durable garments. A better understanding of drivers a

BACKGROUND: A history of preeclampsia is associated with increased risk of coronary artery disease and experimental evidence suggests that a history of preeclampsia also increases the risk of restenosis. However, the extent to which a history of preeclampsia is associated with risk of restenosis after percutaneous coronary intervention in women is unknown. METHODS AND RESULTS: We included 6065 par

Bomb pulse refers to the sharp increase of the atmospheric levels of the carbon isotope 14C due to nuclear testing during the late 1950s and early 1960s. After the nuclear test ban, atmospheric 14C levels decreased exponentially because of the diffusion and equilibration with the ocean and biosphere, as well as the incorporation indirectly into all living cells. Thus, assessing the anthropogeni

Antimony (Sb) is a toxic metalloid, which has been increasingly used in the brake lining of vehicles, and increased concentrations have been found in soils near abundant traffic. However, since very few investigations of Sb accumulation in urban vegetation have been undertaken there exists a knowledge gap. We studied the concentrations of Sb in leaves and needles of trees in the Gothenburg City ar
