Despite their tiny eyes and brains, nocturnal insects have evolved a remarkable capacity to visually navigate at night. Whereas some use moonlight or the stars as celestial compass cues to maintain a straight-line course, others use visual landmarks to navigate to and from their nest. These impressive abilities rely on highly sensitive compound eyes and specialized visual processing strategies in
Human-Computer Interaction (HCI) is an umbrella domain for many areas of study. This paper will look at those topics of HCI known as affective aspects. Affective aspects investigate emotional responses that the user communicates, both verbally and physically, when working with a computer including before and after the work is done. This paper examines the question of improving pedagogy and curricu
We present an optimization procedure that mixes advanced large-scale optimization methods and heuristics to solve large instances (with over 1.7 million integer variables) of the routing and spectrum allocation (RSA) problem - a basic optimization problem in flexgrid elastic optical networks. We formulate the problem as a mixed-integer program for which we develop a branch-and-price algorithm enha
We present an on-chip acoustofluidic platform for harvesting a target microalgal species from a heterogeneous population of cells and particles based on their size, density, and compressibility in a rapid, non-invasive, energy-efficient, continuously running, and automated manner. For our proof-of-principle demonstration, we use Euglena gracilis as a target species. Specifically, we show the simul
Bats are currently killed in large numbers at wind turbines worldwide, but the ultimate reason why this happens remains poorly understood. One hypothesis is that bats visit wind turbines to feed on insects exposed at the turbine towers. We used single molecule next generation DNA sequencing to identify stomach contents of 18 bats of four species (Pipistrellus pygmaeus, Nyctalus noctula, Eptesicus
Municipal wastewater treatment plants are constantly forced to make improvements. The main objectives are to reduce energy consumption, to increase the treatment capacity and to improve the effluent water quality. Microsieves in combination with chemical pretreatment can potentially fulfil these objectives. In this work, experiments were mainly conducted at the large pilot scale, and supplementaryMunicipal wastewater treatment plants are constantly forced to make improvements.

A new large igneous province (LIP), the 1501 ± 3 Ma Kuonamka LIP, extends across 700 km of northern Siberia and is linked with coeval dikes and sills in the formerly attached Sao Francisco craton (SFC)-Congo craton to yield a short-duration event 2000 km across. The age of the Kuonamka LIP can be summarized as 1501 ± 3 Ma (95% confidence), based on 7 U-Pb ID-TIMS ages (6 new herein) from dolerite
A photographic play in five acts based on Poe's The Raven and Lou Reed's lyric. Raven is the Trickster, the one who became and remained everything to every man - god, animal, human being, buffoon, he was before good and evil, denier, affirmer, destroyer and creator.
The seasonality of solar irradiance and precipitation may regulate seasonal variations in tropical forests carbon cycling. Controversy remains over their importance as drivers of seasonal dynamics of net primary productivity in tropical forests. We use ground data from nine lowland Amazonian forest plots collected over 3 years to quantify the monthly primary productivity (NPP) of leaves, reproduct
Around the globe more than 350,000 citizens live with a sophisticated hearing aid device called Cochlear Implant. In many countries CI is an institutionalized medical procedure for restoring deafened with a technological sense of hearing but the social challenges for users is a largely unexplored issue. Addressing this social dimension, the article explores how Cochlear Implant works as a boundary
A theoretical framework for understanding public library development is presented; plural agonistics is used in combination with an approach inspired by post-humanism. The framework is related to examples from a study of two Swedish public libraries. Antagonism is viewed as foundational, and democracy as an ongoing process, the task being to transform antagonism to agonism, with institutions like
PurposeThe purpose of this paper is to advocate and contribute to a more nuanced and discerning argument when ascribing a democratic role to libraries and activities related to information literacy.Design/methodology/approachThe connections between democracy and libraries as well as between citizenship and information literacy are analysed by using Mouffe’s agonistic pluralism. One example is prov
Empathy concerns the feeling of understanding others’ experiences from their perspective, and confronts you with the presence of a qualitative experience that you are not living through yourself. In aesthetics empathy has been conceived as bodily inner imitation. Taking a theoretical, interdisciplinary approach that merges insights from psychology, philosophy, and phenomenology within the dynamic
Grundämnena molybden, wolfram och vanadin spelar viktiga roller i biologiska system. De återfinns bl a i ett antal enzymer, där de genomför s k syreöverföringsreaktioner, d v s de tar en syreatom från en molekyl och överför den till en annan molekyl. Sådana reaktioner är av stor vikt i kemi, eftersom införandet av syre i olika molekyler är viktig vid framställning av många kemikalier som kan använA series of new dioxomolybdenum(VI) and -tungsten(VI) complexes of tripodal tetradentate and tridentate amino bis- and monophenolate ligands have been synthesized and characterized. The majority of the complexes are mononuclear, but dimeric and trimeric oxo-bridged M(VI) (M = Mo, W) were also obtained. The reactivities of all complexes have been investigated in oxygen atom transfer (OAT) processes
This study documents the advancement of laying dates in three species of tits (Paridae) in southernmost Sweden during recent decades, and the absence of a similar response in the pied flycatcher Ficedula hypoleuca. It is based on several different nestbox studies; the oldest one starting in 1969. During 1969 to 2012, mean spring temperatures in the study area increased by between 0.06 and 0.08 °C This study documents the advancement of laying dates in three species of tits (Paridae) in southernmost Sweden during recent decades, and the absence of a similar response in the pied flycatcher Ficedula hypoleuca.
