Permeability and Thermal Conductivity Measurements of Near Surface Units at the Wairakei Geothermal Field, New Zealand

ABSTRACT Thirty one outcrop and drill core samples (to about -500 mRL) from geothermal wells from Te Mihi, western Wairakei Geothermal Field (New Zealand), have been analysed for their mineral assemblage and hydrothermal alteration, thermal conductivity, permeability, bulk rock porosity and density, as part of a study on the affect of the geological parameters on the thermal conductivity. At Wairakei, cores of Huka Falls Formation (soft, lacustrinedeposited tuff and sediments), Waiora Formation (variably consolidated, medium hard, hydrothermally altered volcanic tuff) and Karapiti Rhyolite (hard, altered rhyolite lava and breccias) were analysed from wells WK223, WK224 and WK227 (unaltered/least altered field margin); WK206, WK207, WK212, WK219 and WK247 (Te Mihi upflow zone); and WKM14, WK205, WK210, WK213 and WK221 (infield, south and east of Te Mihi). The effect of hydrothermal alteration (rank and intensity) on thermal conductivity was tested by analysing samples from the same stratigraphic units from different wells, albeit with a range of styles of hydrothermal alteration (e.g. claydominated argillic, characterised by a progression from smectite to illite-dominated clay assemblages, to propylitic). Results demonstrate a good correlation between porosity and thermal conductivity, but no clear relationship between permeability and thermal conductivity. We also compared permeability and thermal conductivity from the Wairakei Field samples with data from rocks in central Europe

Potentials of Thermal Energy Storage Integrated into Steam Power Plants

For conventional power plants, the integration of thermal energy storage opens up a promising opportunity to meet future technical requirements in terms of flexibility while at the same time improving cost-effectiveness. In the FLEXI-TES joint project, the flexibilization of coal-fired steam power plants by integrating thermal energy storage (TES) into the power plant process is being investigated. In the concept phase at the beginning of the research project, various storage integration concepts were developed and evaluated. Finally, three lead concepts with different storage technologies and integration points in the power plant were identified. By means of stationary system simulations, the changes of net power output during charging and discharging as well as different storage efficiencies were calculated. Depending on the concept and the operating strategy, a reduction of the minimum load by up to 4% of the net capacity during charging and a load increase by up to 5% of the net capacity during discharging are possible. Storage efficiencies of up to 80% can be achieved

General practitioner-centred paediatric primary care reduces risk of hospitalisation for mental disorders in children and adolescents with ADHD: findings from a retrospective cohort study

Background: General practitioners (GPs) play an essential role in the sustainable management of attention-deficit/hyperactivity disorder (ADHD). To our knowledge, the healthcare programme described here is the first integrated care programme for paediatric ambulatory care embedded in GP-centred-healthcare in Germany. Objectives: To compare the health-service-utilisation of patients with ADHD enrolled in a GP-centred-paediatric-primary-care-programme with usual care in terms of disease-related hospitalisation, pharmacotherapy and psychotherapy. Methods: In 2018, we conducted a retrospective cohort study of 3- to 18-year-old patients with ADHD in Baden-Wuerttemberg, southern Germany. The intervention group (IG) comprised patients enrolled in a GP-centred-paediatric-primary-healthcare-programme and consulted a participating GP for ADHD at least once. GP-centred-paediatric-primary-care provides high continuity of care, facilitated access to specialist care, extended routine examinations and enhanced transition to adult healthcare. Patients in the control group (CG) received usual care, meaning they consulted a non-participating GP for ADHD at least once. Main outcomes were disease-related hospitalisation, pharmacotherapy and psychotherapy. Multivariable logistic regression was performed to compare groups. Results: A total of 2317 patients were included in IG and 4177 patients in CG. Mean age was 8.9 ± 4.4. The risk of mental-disorder-related hospitalisations was lower in IG than CG (odds ratio (OR): 0.666, 95% confidence interval (CI): 0.509-0.871). The prescription rate for stimulants was lower in IG (OR: 0.817; 95% CI: 0.732-0.912). There was no statistically significant difference in the participation rate of patients in cognitive behavioural therapy between groups (OR: 0.752; 95% CI: 0.523-1.080). Conclusion: Children and adolescents with ADHD enrolled in GP-centred-paediatric-primary-care are at lower risk of mental-disorder-related hospitalisation and less likely to receive stimulants.

Ältere Einfamilienhausgebiete im Umbruch: eine unterschätzte planerische Herausforderung - zur Situation in Nordrhein-Westfalen

Das Thema "Einfamilienhausgebiete im Umbruch" ist eine unterschätzte Herausforderung für viele Kommunen. Derzeit steht es noch nicht im Fokus politischer, planerischer und wissenschaftlicher Debatten. Insbesondere die Flüchtlingszuwanderung in den letzten Jahren hat die Diskussion um die Gestaltung von Raumentwicklung unter Schrumpfungsbedingungen in vielen Regionen ausgesetzt. Dabei werden die grundsätzlichen demografischen und gesellschaftlichen Megatrends von Schrumpfung, Alterung und Metropolisierung durch kurzfristige demografische Trendänderungen in der langfristigen Entwicklungsperspektive nicht merklich verändert werden. Die Auswirkungen des demografischen und gesellschaftlichen Wandels und die damit verbundene veränderte Marktsituation führen zu einer Umbruchsituation in immer mehr Einfamilienhaus-Gebieten (kurz: EFH-Gebiete) der 1950er bis 1970er Jahre. Es lassen sich regional unterschiedliche Betroffenheiten älterer EFH-Gebiete identifizieren. Dementsprechend lassen sich für unterschiedliche Raumkategorien verschiedene städtebauliche Ziele und Handlungsbedarfe mit unterschiedlichen Prioritäten hinsichtlich des Umgangs mit älteren Einfamilienhausbeständen ableiten

The future of dialects: Selected papers from Methods in Dialectology XV

Traditional dialects have been encroached upon by the increasing mobility of their speakers and by the onslaught of national languages in education and mass media. Typically, older dialects are “leveling” to become more like national languages. This is regrettable when the last articulate traces of a culture are lost, but it also promotes a complex dynamics of interaction as speakers shift from dialect to standard and to intermediate compromises between the two in their forms of speech. Varieties of speech thus live on in modern communities, where they still function to mark provenance, but increasingly cultural and social provenance as opposed to pure geography. They arise at times from the need to function throughout the different groups in society, but they also may have roots in immigrants’ speech, and just as certainly from the ineluctable dynamics of groups wishing to express their identity to themselves and to the world. The future of dialects is a selection of the papers presented at Methods in Dialectology XV, held in Groningen, the Netherlands, 11-15 August 2014. While the focus is on methodology, the volume also includes specialized studies on varieties of Catalan, Breton, Croatian, (Belgian) Dutch, English (in the US, the UK and in Japan), German (including Swiss German), Italian (including Tyrolean Italian), Japanese, and Spanish as well as on heritage languages in Canada
