The lightbrown apple moth, Epiphyas postvittana is an increasingly global pest of horticultural crops. Like other moths, E. postvittana relies on olfactory cues to locate mates and oviposition sites. To detect these cues, moths have evolved families of genes encoding elements of the peripheral olfactory reception system, including odor carriers, receptors and degrading enzymes. Here we undertake a

Homelessness in South Africa is a multi-faceted issue with enormous dimensions; an issue which is deeply interrelated with questions of power, human dignity and social justice. In South Africa, women have been frequently neglected and marginalized with regard to contemporary housing policy and practice. In seeking to understand the nature of this marginalization, this paper focuses on structural d

The Douglas-Rachford and Peaceman-Rachford splitting methods are common choices for temporal discretizations of evolution equations. In this paper we combine these methods with spatial discretizations fulfilling some easily verifiable criteria. In the setting of linear dissipative evolution equations we prove optimal convergence orders, simultaneously in time and space. We apply our abstract resul

Background: GEOMAGIA50.v3 is a comprehensive online database providing access to published paleomagnetic, rock magnetic, and chronological data from a variety of materials that record Earth's magnetic field over the past 50 ka. Findings: Since its original release in 2006, the structure and function of the database have been updated and a significant number of data have been added. Notable modific

Background: GEOMAGIA50.v3 for sediments is a comprehensive online database providing access to published paleomagnetic, rock magnetic, and chronological data obtained from lake and marine sediments deposited over the past 50 ka. Its objective is to catalogue data that will improve our understanding of changes in the geomagnetic field, physical environments, and climate. Findings: GEOMAGIA50.v3 for

Denna avhandling undersöker utvecklingen av en tio års engagemang av tillgänglighet i utemiljön. Denna undersöks från två perspektiv; samhällets utmaning och användarens uppfattning. Äldre personer och personer med funktionshinder ska ha lika möjligheter att använda transportsystemet som andra människor. Deras tillgång till transportsystemet är dock ofta begränsad på grund av fysiska hinder i utemIn an inaccessible outdoor environment, older people and people with disabilities can experience environmental barriers. The environmental barriers can restrict them and their abilities to walk. Environmental barriers can be avoided by designing the outdoor environment to meet the needs of older people and people with disabilities. This thesis focuses on accessibility in Sweden from two perspectiv

Reconstructions of the Holocene geomagnetic field and how it varies on millennial timescales are important for understanding processes in the core but may also be used to study long-term solar-terrestrial relationships and as relative dating tools for geological and archaeological archives. Here, we present a new family of spherical harmonic geomagnetic field models spanning the past 9000 yr based

Geomagnetic and mineral magnetic data provide geological indices that are both independent of human impact (i.e. geomagnetic) and respond to human-induced environmental impact (i.e. mineral magnetic). We provide the first discussion of such magnetic events for help in defining the Anthropocene. Within the Holocene, a potential geomagnetic marker for the Anthropocene is the low dipole latitude at c

Det senaste decennierna har byggbranschen uppvisat en stor skara skadefall och problem i hus som på ett eller annat sätt är fuktrelaterade. Många skade- och problemtyper har funnits under hela perioden och återkommer mer eller mindre ständigt. Andra skadetyper har uppkommit "plötsligt" och blivit en ny typ av skador. Så småningom har man lärt sig hur man skall undvika och åtgärda dessa, men snart

Molecular hydrogen exists in two spin-rotation coupled states: parahydrogen and orthohydrogen. Due to the variation of energy with rotational level, the occupation of ortho- and parahydrogen states is temperature dependent, with parahydrogen being the dominant species at low temperatures. The equilibrium at 20 K (99.8% parahydrogen) can be reached by natural conversion only after a lengthy process
