    International Workshop on Magnetic Fields and Star Formation, APR 21-25, 2003, Madrid, SPAINProfiles of the UV semiforbidden lines of C III](1908) and Si III](1892) of RW Aur have been obtained with the HST/STIS. The C III](1908) profile shows two high velocity components at v = +/- 170 km s(-1) and a central one. The Si III](1892) profile is very broad (FWHM = 293 km s(-1)) and the high velocity components are unresolved. It is shown that the high velocity components are most probably produced in a rotating belt alike the detected in other sources of bipolar outflows. A radius between 2.7 R-* and the corotation radius (6.1 R-*) is derived and a log T-e ( K) similar or equal to 4.7 and log n(e)(cm(-3)) = 11.6 are estimated. The belt is clumpy and the most likely source of heating is local X-rays radiation, probably associated with the release of magnetic energy.Unidad Deptal. de Astronomía y GeodesiaFac. de Ciencias MatemáticasTRUEpu

    Estimating the Aquifer’s Renewable Water to Mitigate the Challenges of Upcoming Megadrought Events

    In arid and semi-arid regions of the world, the occurrence of prolonged drought events (megadroughts) associated with climate change can seriously affect the balance between water supply and demand, thereby severely increasing the susceptibility of such regions to adverse impacts. In this study, a simple framework is introduced to estimate renewable water volumes (RW) to mitigate the challenges of megadrought events by managing the groundwater resources. The framework connects a weighted annual hydrological drought index (wSPEI) to RW, based on the short time-scale precipitation volume. The proposed framework, which was in a proof-of-concept case study applied to the Neishaboor watershed in the semi-arid part of Iran, showed that developing the weighted drought index can be valuable to estimate RW. The results suggested that the wSPEI, aggregating hydrological drought index (HSPEI) with the time scale k = 5 days and the regional coefficient s = 1.3 can be used to estimate RW with reasonable accuracy (R2 = 0.73, RMSE = 11.5 mm year−1). This indicates that in the Neishaboor watershed, the best estimation of RW can be determined by precipitation volumes (or the lack thereof) falling over 5-day aggregation periods rather than by any other time scales. The accuracy of the relationship was then investigated by cross validation (leave-one-out method). According to the results, the proposed framework performed fairly well for the estimation of RW, with R2 = 0.75 and RMSE = 12.2 mm year−1 for k = 5 days. The Overall agreement between the wSPEI, the RW derived from water balance calculations, and the estimated RW by the proposed framework was also assessed for a period of 34 years. It showed that the annual RW followed closely the wSPEI, indicating a reasonable relationship between wSPEI and the annual RW. Accordingly, the proposed framework is capable to estimate the renewable water of a given watershed for different climate change scenarios.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Water Resource

    Pencegahan Penyakit Infeksi Menular Melalui Edukasi PHBS Pada Masyarakat RW.02 Jungge, Kelurahan Bontoparang, Kabupaten Gowa

    This service aims to provide education regarding how to prevent the emergence of infectious diseases by implementing PHBS cultural practices to the community of RW.02 Jungge. This service is carried out in the Bontoala neighborhood, Bontoparang Village, Gowa Regency. The author uses several stages in the process of service activities, including: the preparation stage, the implementation stage, and the evaluation stage. The service activity was carried out on March 9, 2022, by lecturers and students of the Faculty of Health, Patria Arta University.D uring the service process, the author found that in the preparation stage there were several gaps related to the social conditions of the RW.02 Jungge community such as social status, profession, age, educational background, economic, social, cultural, and health conditions that made the writer decide to use an educational approach. theory and practice to introduce about PHBS. Then in the second stage, namely implementation, the author and his friends did heart exercise, then continued with theoretical education regarding the importance of PHBS and how to apply PHBS using a persuasive approach, panel discussion and door to door methods. And in the third stage or evaluation stage, the writer together with other friends did a cross check by asking the RW residents one by one. 02 Jungge regarding the results and benefits of this service activity. The implementation of PKM was successfully carried out using an educational approach based on theory and practice, obtained by RW residents. O2 Jungge, Gowa Regency by knowing, understanding, and being able to prevent infectious infectious diseases by implementing PHBS.Keywords: Infectious infectious diseases, PHBS Educatio

    Explicit LDP for a slowed RW driven by a symmetric exclusion process

    No full text
    We consider a random walk (RW) driven by a simple symmetric exclusion process (SSE). Rescaling the RW and the SSE in such a way that a joint hydrodynamic limit theorem holds we prove a joint path large deviation principle. The corresponding large deviation rate function can be split into two components, the rate function of the SSE and the one of the RW given the path of the SSE. These components have different structures (Gaussian and Poissonian, respectively) and to overcome this difficulty we make use of the theory of Orlicz spaces. In particular, the component of the rate function corresponding to the RW is explicit.</p

    Date of Conference: 30 March - 3 April, 2008Conference name: 30th European Conference on IR Research ECIR 2008: Advances in Information RetrievalWe show that a cluster-skipping inverted index (CS-IIS) is a practical and efficient file structure to support category-restricted queries for searching Web directories. The query processing strategy with CS-IIS improves CPU time efficiency without imposing any limitations on the directory size. © 2008 Springer-Verlag Berlin Heidelberg
