Induced polarization applied to biogeophysics: recent advances and future prospects

This paper provides an update on the fast-evolving topic of the induced polarization (IP) method applied to biogeophysics. It emphasizes new understandings of the IP phenomena associated with biological activity, pointing out new developments and applications, and identifying existing knowledge gaps. The focus is on the use of IP as related to living organisms, including micro-organisms and plants

Evaluation of spectral induced polarization field measurements in time and frequency domain

Spectral induced polarization (SIP) measurements have been demonstrated to correlate with important parame-ters in hydrogeological and environmental investigations. Although SIP measurements were often collected in thefrequency domain (FDIP), recent developments have demonstrated the capabilities to solve for the frequency-de-pendence of the complex conductivity through measurements collected in t

Comparison of TDIP and SIP measurements in the field scale

The frequency-dependence of the induced polarization effect (IP), in the so-called spectral IP (SIP), has been demonstrated to be strongly correlated to important parameters in hydrogeological and environmental investigations. This has prompted the development of measuring instruments and modelling techniques towards the collection of laboratory and field data with enhanced accuracy and at a broad

IP lab measurements on E. coli-sand-mixtures

Aim of the MIRACHL project is the characterisation and monitoring of in-situ remediation of chlorinated hydrocarbon contamination using an interdisciplinary approach. Therefore, geophysical methods, as e.g. DCIP are used to investigate the remediation process.To interpret these geophysical field IP data, lab investigations with different kinds of bacteria are necessary to assess the sensitivity of

Service users experience of receiving peer support in Swedish mental health care : a “tipping point” in the care-giving culture?

Peer support workers are increasingly considered an essential ingredient in recovery-oriented mental health services. While research continues to point to promising results concerning the ability of these workers to positively impact service users’ experience of hope, quality of life and even health, peer support workers have only recently been introduced in Sweden and the aim of this study was to

Induced Polarisation (IP) laboratory measurements on E. coli sand mixtures

The aim of the MIRACHL project is the characterisation and monitoring of insituremediation of chlorinated hydrocarbon contamination using an interdisciplinary approach and geophysical methods, such as DCIP (direct current induced polarisation) to investigate the remediation process.To interpret these geophysical field IP data, lab investigations with different kinds of bacteria are necessary to as

Geophysical Induced Polarisation (IP) laboratory measurements on E. coli-sand mixtures

PKC activation sensitizes basal-like breast cancer cell lines to Smac mimetics

There is a need for novel strategies to initiate cancer cell death. One approach is the use of Smac mimetics, which antagonize inhibitor of apoptosis proteins (IAPs). Recent studies have shown that combinations of Smac mimetics such as LBW242 or LCL161 in combination with chemotherapeutic agents increase cancer cell death. Here we show that the protein kinase C (PKC) activator TPA together with th

Medical practice at Swedish Cistercian monasteries

Definitions and understandings of disease are to a large extent culturally dependent, even if there are also biological components to this. While many medieval religious orders nursed an interest for science and knowledge in general, their approach to medicine was complicated by the complex attitude towards illness and the tending of the body within Christendom. Archaeological artifacts from Ciste

The Kurdish Movement and the Democratic Federation of Northern Syria: An alternative to the (nation-)state model?

Is the Rojava model really deconstructing the model of a state or is it potentially a new state form? Does the ‘democratic confederalism’ model that the Kurdish movement claims to be implementing in Northern Syria draw on/reproduce different modes of identity/belonging than that of the nation and the state? This paper argues that the shift from a nationalist movement towards a project that offers

Directional Negative Thermal Expansion and Large Poisson Ratio in CH 3 NH 3 PbI 3 Perovskite Revealed by Strong Coherent Shear Phonon Generation

Despite the enormous amount of attention CH 3 NH 3 PbI 3 has received, we are still lacking an in-depth understanding of its basic properties. In particular, the directional mechanical and structural characteristics of this material have remained elusive. Here, we investigate these properties by monitoring the propagation of longitudinal and shear phonons following the absorption of a femtosecond

Importance of In Situ Data in Reducing Uncertainty when Quantifying the African Carbon Budget

Scarcity of in situ measurements of greenhouse gas (GHG) fluxes hamper calibration and validation of continental assessments of carbon budgets in Africa. It limits essential studies of ecosystem functioning and ecosystem processes. Wide reported ranges of estimated African net primary production (NPP) and gross primary production (GPP) is a function of the uncertainty originating from this scarcit

Denne teksten presenterer en side av Marx' filosofi som ikke har fått like mye oppmerksomhet som hans kapitalismekritikk, nemlig hans kritikk av menneskerettighetene. FNs menneskerettighetserklæring regnes i dag som det viktigste dokumentet for internasjonalt samarbeid. Til sammenligning er Marx' syn at menneskerettighetene skaper egoisme og svekker kollektivets samhold. Teksten presenterer dette

Implementation and evaluation of a teacher intervention program on classroom communication

Background: Media frequently report on overall work-place challenges in Swedish schools, including teachers’ working conditions, their well-being, and students’ declining results. Language is the key to success in every school subject. Therefore, optimal language learning environments are important. Poor sound environments affect teachers’ vocal health, their general well-being, and students’ perf

Heparin-Binding Protein As A Prognostic Biomarker of Sepsis and Disease Severity at The Emergency Department

OBJECTIVE: Rapid and early detection of patients at risk to develop sepsis remains demanding. Heparin-binding protein (HBP) has previously demonstrated good prognostic properties in detecting organ dysfunction among patients with suspected infections. This study aimed to evaluate the plasma-levels of HBP as a prognostic biomarker for infection-induced organ dysfunction among patients seeking medic
