A methodology to allow avalanche forecasting on an information retrieval system

This paper presents adaptations and tests undertaken to allow an information retrieval (IR) system to forecast the likelihood of avalanches on a particular day. The forecasting process uses historical data of the weather and avalanche conditions for a large number of days. A method for adapting these data into a form usable by a text-based IR system is first described, followed by tests showing the resulting system’s accuracy to be equal to existing ‘custom built’ forecasting systems. From this, it is concluded that the adaptation methodology is effective at allowing such data to be used in a text-based IR system. A number of advantages in using an IR system for avalanche forecasting are also presented

Transformations between the theoretical and observational planes in the HST-NICMOS and WFPC2 photometric systems

Color-temperature relations and bolometric corrections in the HST-NICMOS F1110W, F160W and F222M and in the WFPC2 F439W, F555W and F814W photometric systems, using two different sets of model atmospheres, have been derived. This database of homogeneous, self-consistent transformations between the theoretical and observational planes also allows combinations of visual and infrared quantities, without any further transformation between the two different photometric systems. The behavior of the inferred quantities with varying the stellar parameters, the adopted model atmospheres and the instrumental configurations are investigated. Suitable relations to transform colors and bolometric corrections from HST to ground-based photometric systems are also provided.Comment: 22 pages, 14 figure

Collars and partitions of hyperbolic cone-surfaces

For compact Riemann surfaces, the collar theorem and Bers' partition theorem are major tools for working with simple closed geodesics. The main goal of this paper is to prove similar theorems for hyperbolic cone-surfaces. Hyperbolic two-dimensional orbifolds are a particular case of such surfaces. We consider all cone angles to be strictly less than $\pi$ to be able to consider partitions.Comment: 11 pages, 9 figures; v2: minor changes, to appear in Geometriae Dedicat

Long-term Outcome after Surgical Closure of Atrial Septal Defect in Childhood with Extensive Assessment Including MRI Measurement of the Ventricles

Surgical closure of the secundum type of atrial septal defect (ASD) in childhood leads to excellent survival. However, relevant morbidity has been reported. Transcatheter closure of these defects has now become an alternative approach. To compare the results of the two different interventions, reliable data are needed on the long-term morbidity after defect closure with both methods. Patients were evaluated after a minimum of 10 years after surgical closure of an ASD in childhood. Assessment included analysis of perioperative data, interview, clinical examination, electrocardiogram, (ECG), 24-hour ECG, ergometry, chest radiograph, echocardiography, and MRI. A total of 66 patients underwent operation between 1971 and 1986 at our institution. Forty-eight of them (73%) were interviewed and 38 (58%) participated fully in the study program. Eighteen (27%) either refused to participate or were lost to follow-up. There were no substantial residual disorders, such as arrhythmias, right-sided heart dilatation, pulmonary hypertension, or reduced work capacity. Surgical closure of an ASD in childhood has an excellent long-term outcome. Surgical closure is thus the standard against which transcatheter closure needs to be measure

The Level of Moral Competence Among Sample of Hashemite University Students

The primary purpose of this study was to determine the level of students’ about moral competence at Hashemite University in Jordan. A total of 909 university students participated in the study by completing the moral competence questionnaire. Results indicate that university students showed medium level of moral competence. Additionally, results indicated that there were significant differences in participants’ level of moral competence based on the demographics of gender, academic level and academic performance. The study ends by suggesting a number of practical and theoretical recommendations for a number of stakeholders

Status febrilis mit Bewusstlosigkeit

Zusammenfassung: Eine zerebrale Beteiligung bei Malaria mit Plasmodium vivax ist ungewöhnlich. Diese schwere Form der Malaria ist üblicherweise durch Plasmodium falciparum bedingt. Wir berichten über eine 18-jährige Patientin aus Pakistan mit langjähriger intermittierender Fieberanamnese, welche 4Monate nach Einreise in die Schweiz erstmals an einer zerebralen Vivax-Malaria erkrankt. Die eindrückliche neurologische Symptomatik mit Amaurosis und Bewusstseinsstörung bildete sich in diesem Fall unter Therapie in wenigen Tagen zurück. Jedoch sind Todesfälle bei zerebraler Malaria durch Plasmodium vivax beschriebe

Interdisciplinary research in Rajasthan, India: exploring the role of culture and art to support rural development and water management

This paper examines the role of art and culture in supporting rural development in the context of critical water challenges. It focuses on an interdisciplinary network and research programme conducted in 2018 with the village of Jhakhoda, in Rajasthan, India. The village has experienced years of declining water quality and has recently turned to rainwater harvesting and other conservation measures as a means to address water challenges. The research team sought to support local NGO and village efforts through creative, regionally specific forms of cultural activity. Through our project, we found that arts approaches can contribute to changes in the way people understand water and environmental challenges and can play a significant role in working towards sustainable water futures

Stable Isotope Event Markers Near the Permo-Triassic Boundary in the Karavanke Mountains (Slovenia)

Stable isotope analyses of carbonates and organic matter from the Permo-Triassic boundary section in the Karavanke Mountains, Slovenia, indicate a further example of the “light carbon” event across the boundary. In this section the changes in carbon isotope values were a direct result of the culmination of the marine regression and associated events at the end of the Permian, which caused a drop in primary productivity, as well as related local environmental changes, with no evidence of any considerable diagenetic overprint
