A Detector System for Light–Element Analysis using a Nuclear Microprobe : for Applications in Geoscience

I detta arbete har två analysmetoder med mycket hög känslighet för att mäta väte och bor utvecklats. Dessa har tillämpats på geologiska material där de kan vara ett verktyg i att svara på frågeställningar gällande b.la. jordskorpans utveckling och flödet av vatten på jorden. Metoderna kan mäta en väte- eller bor-atom bland en miljon andra atomer. Jonstråleanalys är ett fält inom den tillämpade fys

Cows on Facebook and Instagram : Interspecies Intimacy in the Social Media Spaces of the Swedish Dairy Industry

This article analyses producer-consumer relations in social media marketing in the Swedish dairy industry. The article discusses how ideas of interspecies intimacy are publicly performed in an interactive process between the dairy industry producers and social media users. Two examples from the Swedish dairy industry were chosen for analysis, one Instagram account and one Facebook account. The ana

Resource Management for OFDMA based Next Generation 802.11 WLANs

Recently, IEEE 802.11ax Task Group has adapted OFDMA as a new technique for enabling multi-user transmission. It has been also decided that the scheduling duration should be same for all the users in a multi-user OFDMA so that the transmission of the users should end at the same time. In order to realize that condition, the users with insufficient data should transmit null data (i.e. padding) to f

The peripheral olfactory repertoire of the lightbrown apple moth, epiphyas postvittana

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

Homeless Women and Shelter Regimes : A Glimpse of Everyday Practice through Social Workers´Narratives

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

A Full Space-Time Convergence Order Analysis of Operator Splittings for Linear Dissipative Evolution Equations

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

GEOMAGIA50.v3: 1. general structure and modifications to the archeological and volcanic database Recent advances in environmental magnetism and paleomagnetism

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
