Molecularly well-designed proton exchange membranes (PEMs) with a high local concentration of strongly acidic groups have the potential to fulfill the strict requirements for fuel cell operation under high temperature and low humidity. Here, we have prepared a series of well-defined and tunable PEMs based on poly(p-phenylene alkylene) backbones functionalized with sulfonated polypentafluorostyrene
This report was prepared in the context of the LPCC Electroweak Precision Measurements at the LHC WG (https://lpcc.web.cern.ch/lpcc/index.php?page=electroweak_wg) and summarizes the activity of a subgroup dedicated to the systematic comparison of public Monte Carlo codes, which describe the Drell–Yan processes at hadron colliders, in particular at the CERN Large Hadron Collider (LHC). This work re
Supernormal clutches are found across bird species. Such clutches often result from more than one female laying eggs in the same nest and can reflect different behaviours from parasitism to laying mistakes. Enlarged clutches are readily visible among waders due to a maximum maternal clutch size of four eggs, yet surprisingly little is known about this phenomenon. Since supernormal clutches are rar
Changes in the inlet morphology of choked coastal lagoons often restrict the water exchange with the sea, making them vulnerable to pollution events and eutrophication processes. In this study, the importance of tides for the water exchange was investigated in Mundaú Lagoon, which is a choked lagoon located in northeastern Brazil that has a very dynamic inlet and channel system. The analysis was c
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
Purpose: We wanted to compare optic nerve head topography measurements and discrimination between normal and glaucomatous eyes with two entirely different three-dimensional optic disc imaging techniques, confocal scanning laser tomography (Heidelberg Retina Tomograph, Heidelberg Engineering) and raster tomography (Glaucoma-Scope, Ophthalmic Imaging Systems). Methods: Both eyes of 225 normal subjec
Creatine kinase (CK) isoenzymes, with emphasis on the mitochondrial CK isoenzymes, were characterized and localized in chicken cerebellum. Chicken cerebellar extracts analyzed by two-dimensional gels, using anti-peptide antibodies specific for sarcomeric muscle-type mitochondrial CK (Mib-CK) and revealed the presence of a Mib-CK variant in avian cerebellum. This CK isoform was localized by immunof
This thesis is about how and why employees spend large proportions of their working hours on empty labor, i.e. private activities on the job. It is written against the backdrop of a highly debated subject within critical theory, namely the possibility of individuals resisting taken-for-granted power asymmetries. Critical theorists' stress on ideological power and the internalization of submission
The distribution of serotoninergic neurons in the brain of the three‐spined stickleback was demonstrated with the indirect peroxidase‐antiperoxidase (PAP) immunohistochemical method with antibodies against serotonin. Serotoninergic perikarya were demonstrated in the brainstem reticular formation (nucleus raphe dorsalis, nucleus raphe medialis, and nucleus tegmenti dorsalis lateralis) and in the pe
Background: The axillary web syndrome (AWS) occurs in the axilla and on the frontal side of the upper arm and sometimes along the forearm to the thumb. The cord is painful, particularly on movement, and can therefore be very distressing for the patient. Although the phenomenon has been examined and discussed for decades, no evidence for the origin has been found until now. The aim of this study
Transplantation of porcine embryonic brain cells, including dopaminergic neurons, from ventral mesencephalon (VM) is considered a potential treatment for patients with Parkinson's disease. In the present study, we characterized the distribution among VM cells of the major porcine endothelial xenoantigen, the Galalpha1,3Gal epitope, and evaluated the cytotoxic effect of anti-Galalpha1,3Gal antibody
Experimental studies on protein dynamics at atomic resolution by NMR-spectroscopy in solution require isolated 1H-X spin pairs. This is the default scenario in standard 1H-15N backbone experiments. Side chain dynamic experiments, which allow to study specific local processes like proton-transfer, or tautomerization, require isolated 1H-13C sites which must be produced by site-selective 13C labelin
The effect of illumination at 5 K of photosystem II in different S-states was investigated with EPR spectroscopy. Two split radical EPR signals around g 2.0 were observed from samples given 0 and 3 flashes, respectively. The signal from the 0-flash sample was narrow, with a width of ~80 G, in which the low-field peak can be distinguished. This signal oscillated with the S1 state in the sample. The
We reconstructed forest development and disturbance events (fire and logging) during the last 1000 yr with tree-ring data, pollen and charcoal analysis from a semi-natural Fagus sylvatica-Picea abies forest (ca. I km(2)) in the hemiboreal zone. According to pollen analysis, Quercus robur together with Pinus sylvestris was abundant in the forest until the turn of the 18th/19th centuries when these
This study seeks an understanding of how Facebook users cope with the impact of anti-tobacco shock advertising by posting comments on Facebook. It also clarifies how healthcare organisations help these people re-construct themselves online after they have been shocked. The effectiveness of shock advertising at changing harmful behaviours has been extensively studied in the field of strategic commu
I denna uppsats behandlas den svenska regleringen av barnpornografibrottet och vad den omfattar efter 2010 års lagändring. Syftet med uppsatsen är att belysa om syftet med lagändringen har uppnåtts, att göra all befattning olagligt för att mer effektivt kunna bekämpa barnpornografi. Uppsatsen ger en detaljerad redogörelse för de ändringar som gjorts sedan regleringen infördes 1980. Utöver det tas In this essay the Swedish regulation regarding child pornography is discussed focused on parts included in the regulation after the amendment 2010. The purpose is to discuss if the intention with the new amendment has been achieved, that is to criminalize all types of behaviors related to child pornography for enabling more effective crime prevention. The essay presents a thorough review on what c
Levnadsförhållandena är vanligtvis låga för människor som lever i flytande byar runt om i världen. Avsaknaden av adekvata avfallssystem i flytande byar försämrar både människors hälsa samtidigt som sjöar kontamineras. Detta examensarbete utvärderar hållbarheten av att implementera flytande bioreaktorer som avfallssystem för flytande byar i sjön Tonlé Sap, Kambodja. Det huvudsakliga syftet är att bConditions for humans living in floating villages around the world are usually in the lowest earning bracket. The lack of sanitary facilities pollutes lakes and deteriorates human health. This master thesis evaluates the environmental sustainability of implementing floating biodigesters as a sanitary solution in a village located on the lake Tonlé Sap in Cambodia. The main objectives include asses
Electric road systems (ERS) provide electric power to vehicles en route (dynamic charging) and can reduce the need for onboard battery capacity. This thesis sets out to examine the power demand of an ERS and the integration of energy storage in its power supply for grid load alleviation and backup power. Specifically, the analysis is based on the ongoing project to build a permanent ERS on a 21 km
Abstract in Undetermined This study used passive telemetry (passive integrated transponders) to evaluate winter migration in three species of cyprinids (roach (Rutilus rutilus (L.)), white bream (Blicca bjoerkna (L.)) and rudd (Scardinius erythrophthalmus (L.))) and their potential predators (pike (Esox lucius (L.)) and perch (Perca fluviatilis (L.))) between a shallow lake and its streams.
