= 6.1 1910 Adra earthquake (southern Spain)
No full textWe examine and model analogue recordings from 6 early mechanical seismographs for the 1910 June 16 earthquake at Adra, Southern Spain. Modern standard, time-domain analysis techniques were applied to the historical data to estimate the source parameters of the event: The regional sparse network data were inverted for the deviatoric seismic moment tensor. The best moment tensor solution corresponds to a M o = 1.50 . 10 18 Nm, M w 6.1 oblique strike-slip event at 16 km depth. Our preferred faulting solution is: strike 122°, dip 80° rake - 137°, in very good agreement with available neo- and seismotectonic data. The source time function of this earthquake was estimated by deconvolving recordings of a M w 5.5 aftershock that occurred the same day. The time function indicates a total rupture time of 4.5 s, corresponding to estimates for mainshock rupture length of 12 km, and stress drop of 29 bar.</p
Az Adra Alapítvány élményterápiás programja, avagy nonprofit szervezete a hátrányos helyzetű gyermekekért
No full textAz ADRA Adventista Fejlesztési és Segély Alapítvány a Hetednapi Adventista Egyház nemzetközi humanitárius segélyszervezetének élményterápiás programja áll a dolgozat középpontjában. Mely program kedvezményezettjei a halmozottan hátrányos helyzetű gyermekek hazánkban országszerte. A szociális ellátórendszerrel és egy külföldi nonprofit szervezettel együttműködésben valósítjuk meg a projektet évről évre. A szakdolgozatomban a jóléti állam működéséről, mint háttéről írtam, és az ADRA Alapítványra vonatkoztatva a nonprofit szervezeti működésről, továbbá a szervezet önkéntes programjáról is. A szerkezeti felépítésében a dolgozatomnak a szegénység, a gyermekszegénység és a halmozottan hátrányos helyzetű gyermekek témája is bemutatásra kerül, ez utóbbi csak nagyon vázlatosan megjelenítve. Az ADRA önkénteseivel végzett interjúk bemutató elemzése is a dolgozat tárgya, és azoknak a következtetéseknek a megfogalmazása is, melyek már az alapítvány önkéntes stratégiájának, és önkéntes menedzsmentjének részét képezik. Választ kerestem arra a kérdésre, hogy milyen hatással vannak egy nonprofit szervezet önkéntesei a hátrányokkal élő gyermekekre? A válaszok között olyan hiteles, valódi történések jelennek meg, melyek erősítik az ADRA Alapítvány, mint önkénteseket fogadó közhasznú szervezet identitását. Egyfelől az önkénteseinek elkötelezettsége, másfelől a támogatott gyermekek számára átadott értékek és pozitív szocializációs minták tekintetében.LBSzociálpolitikaMSc/M
Shear-wave velocity structure from MASW and SPAC methods: The case of Adra town, SE Spain
No full textThe damage distribution in the town of Adra (south-eastern Spain) during the 1993 and 1994 Adra earthquakes of magnitude Mw~5.0 and maximum intensity degree of VII (European Macroseismic Scale) was mainly concentrated in the southeast sector, where the low-diagenetic (soft) sediments outcrop. As new urbanizations are being planned in this sector, a soil classification based on the shallow shear-wave velocity (Vs) structure is needed. For the purpose of earthquake disaster mitigation, the Spatial Autocorrelation (SPAC) and the Multichannel Analysis of Surface Waves (MASW) methods were used to propose integrated 2D Vs models for the seismic response characterization of the shallow geology. Joint inversion of H/V spectral ratios of ambient noise, interpreted under the Diffuse Field Approach and the dispersion curves derived from the SPAC method allowed us to obtain more constrained models. Both SPAC and MASW methods provided similar results for the surveyed geological formations. From these models, a classification of the geological formations was carried out in terms of Vs30 values and Eurocode 8 (European Committee for Standardization 1998) classes. Lower Vs30 values in the 180-360 m/s range were found in the southeastern sector of the town, where soft sediments outcrop and some building damage was reported during the 1993-1994 earthquakes. The highest Vs30 values exceeding 800 m/s appear in the northern sector, where the hardest rocks outcrop and no building damage was reported. The combination of the well-suited Vs database prepared for different geological formations with the 1:5,000 scale geological mapping was an important step to obtain the detailed soil microzonation map of Adra. This approach offered a new predictive insight into the building damage distribution, which would contribute to the appropriate urban planning for the future growth of the town. © 2018 European Association of Geoscientists & Engineers.Universidad Autónoma de Chil
Immunomodulation by mesenchymal stem cells : a potential therapeutic strategy for type 1 diabetes
No full textMesenchymal stem cells (MSCs) are pluripotent stromal cells that have the potential to give rise to cells of diverse lineages. Interestingly, MSCs can be found in virtually all postnatal tissues. The main criteria currently used to characterize and identify these cells are the capacity for self-renewal and differentiation into tissues of mesodermal origin, combined with a lack in expression of certain hematopoietic molecules. Because of their developmental plasticity, the notion of MSC-based therapeutic intervention has become an emerging strategy for the replacement of injured tissues. MSCs have also been noted to possess the ability to impart profound immunomodulatory effects in vivo. Indeed, some of the initial observations regarding MSC protection from tissue injury once thought mediated by tissue regeneration may, in reality, result from immunomodulation. Whereas the exact mechanisms underlying the immunomodulatory functions of MSC remain largely unknown, these cells have been exploited in a variety of clinical trials aimed at reducing the burden of immune-mediated disease. This article focuses on recent advances that have broadened our understanding of the immunomodulatory properties of MSC and provides insight as to their potential for clinical use as a cell-based therapy for immune-mediated disorders and, in particular, type 1 diabetes

Guadalfeo and Adra submarine deltas evolution in response to sediment supply variations
No full textThe Guadalfeo and the Adra submarine deltas off the northern coast of the Alboran Sea have been built up under the direct influence of short and mountainous rivers. The area is subjected to strong climatic seasonality, with sporadic winter torrential floods and high summer aridity. In addition numerous anthropogenic activities have affected these systems, mostly during the last two centuries. In order to decode the influence of climatic variability and anthropogenic impacts on sediment supplies during the recent past, five sediment cores were collected from the Guadalfeo and Adra submarine deltas. Benthic foraminiferal and sedimentological analyses, combined with radiocarbon dating, were performed.
The impact of torrential floods alternating with periods of low rainfall or dry periods were recorded in the Adra and Guadalfeo prodeltas. Periods with low abundance of benthic foraminifera and high amounts of coarse-grained sediments, were interpreted as the result of enhanced sediment supply to the shelf triggered by major flood events. On the other hand, periods with high amounts of fine-grained sediments and high abundances of colonizers and opportunistic foraminiferal species indicate the establishment of new environments with distinct ecological constraints. These environments were driven by lower sediment supplies during low rainfall or dry periods. The most recent sedimentation seems to reflect the human interventions in the rivers basins, such as deviation of the main river courses and dams construction, which reduced the sediment input and promoted the deposition of shallow-water submarine deltas.info:eu-repo/semantics/publishedVersio

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
