ASD, Eating Problems, and Overlap with Anorexia and Bulimia Nervosa

Abnormal eating behaviors are overrepresented in the autism spectrum disorders, including food refusal, pica, rumination, and selective eating. Those disturbances can have detrimental complications and are often resistant to treatment. In autism spectrum disorders the background factors to eating disturbances are more complex than in the general child population, and sensory abnormalities, rituali

The Library Treasure Hunt: Reach for the Stars. Introducing First Year Students to the Landscape of Scientific Information

One important task for the librarians at Physics and Astronomy Library at Lund University is to teach the students about the library and its resources. The traditional lectures and tours of the library just weren’t working. The library competes with many other introductory activities, such as general orientation, and social events. The aim of the Treasure Hunt is to present the library in a useful

Remote fluorescence lidar imaging of monuments: the Coliseum and the Lateran Baptistery in Rome

On site remote laser-induced fluorescence measurements have been performed with application towards non-movable objects. This paper describes the application of non-invasive hyperspectral fluorescence imaging to two masonry monuments, the Coliseum and the Lateran Baptistery in Rome, during a joint Italian-Swedish experiment. The mobile systems of Lund Institute of Technology, Sweden, and CNR-IFAC,

On the relation between morphology and syntax.

According to the traditional view, the relation between morphology and syntax is the following: while morphology builds up word forms—typically by combining roots with other roots and with affixes, but also by applying other operations to them, syntax takes fully inflected words as input and combines them into phrases and sentences. The division of labour between morphology and syntax is thus perf

Cultural evolution and archaeology : Historical and cultural trends

The 10th Nordic TAG conference fell together with the 150th anniversary of the publication of Charles Darwin’s seminal On the Origin of Species as well as the 200th anniversary of his birth. Over the last 15 years a new theoretical discourse on the use of evolutionary theory in archaeology has emerged, but this has largely bypassed the Scandinavian countries, despite the fact that Scandinavian arc

Experimental and computational investigation of machining processes for functionally graded materials

Experiments on dry face turning offunctionallygraded heat treatable steel are conducted. The workpieces have a hardened zone of approx. 60 HRC and a non-hardened zone of approx. 30 HRC. PCBN tools are used with different feeds, cutting speeds and depths of cut. Measurements of residual stresses in the surface layer reveal compressive stresses in the hardened zone and tensile stresses in the non-ha

Climatised Moves : Climate-induced Migration and the Politics of Environmental Discourse

Popular Abstract in English Climate migration has become an iconic topic in international climate politics and policy. This work, combining political ecology, critical security studies and post-foundational theories, traces the changes of conflicting discourses across time and space, and assesses the different forms of security they interpellate. While initially attracting attention as a securityThis work seeks to de-naturalise climate-induced migration (CM). Combining political ecology and post-foundational theories, I read CM as a construct that reifies a series of phenomena into an issue to be researched and governed. By assessing the narratives, the knowledge, the logics and imaginaries on which conflicting discourses are built, I analyse the strategies of government they envision. I

Pheromone-mediated mating system in a moth species

Popular Abstract in Swedish Feromonmedierat parningssystem hos ett nattfly Min avhandlings huvudsakliga mål är att identifiera och bestämma faktorer som påverkar det feromon-medierade parningsystemet hos sädesbroddflyet Agrotis segetum. Dessa faktorer inkluderar både honkönets produktion av sexualferomon såväl som hankönets feromon-inducerade respons, men också andra överlevnads- och reproduktionIn a series of studies, carried out in the laboratory and in the field in southern Sweden, I have examined factors influencing the mating behaviour of the turnip moth Agrotis segetum. The reproductive potential of the sexes and the mating behaviour was studied. The reproductive potential of males is greater than that of females. Males are ready to mate every night, while females rarely mate more

Communication in Humans and Other Animals

Communication is a basic behaviour, found across animal species. Human language is often thought of as a unique system, which separates humans from other animals. This textbook serves as a guide to different types of communication, and suggests that each is unique in its own way: human verbal and nonverbal communication, communication in nonhuman primates, in dogs and in birds. Research questions

Quantum chaos and regularity in ultracold Fermi gases

Quantum fluctuation of the energy is studied for an ultracold gas of interacting fermions trapped in a three-dimensional potential. Periodic-orbit theory is explored, and energy fluctuations are studied versus the particle number for generic regular and chaotic systems, as well as for a system defined by a harmonic confinement potential. Temperature effects on the energy fluctuations are investiga

Spectroscopic studies of III-V semiconductors in two, one and zero dimensions

Popular Abstract in Swedish I slutet av 1800-talet gjordes upptäckten att atomer bara kan ta upp eller sända ut ljus med vissa våglängder. Denna egenskap beror på att elektronerna endast kan befinna sig i ett av flera diskreta energitillstånd. Man säger att elektronerna är kvantiserade. Kvantiseringen är en effekt av att elektronerna i en atom tvingas hålla sig inom en mycket liten volym. Ju mindrIn this thesis, spectroscopic studies of quantum wells (QWs), quantum wires (QWRs) and quantum dots (QDs) in III-V semiconductors are presented. The electronic structure of these low-dimensional structures have been studied by absorption, photocurrent, electroreflectance, photoluminescence (PL), and photoluminescence excitation (PLE) spectroscopy. The band alignment of GaAs pseudomorphically grow
