Towards a More Effective Hospital: Helping Health Professionals to Learn from their Own Practice by Developing an Easy to use Clinical Processes Quer…
2016
Application of complex socio-technical systems theory to optimization of clinical processes in hospitals highlights the importance of the acceptance and promotion of responsible autonomy among health professionals. Therefore the independent ability for clinicians to search for answers to questions which are outside the scope of pre-made reports is important. However, the ad-hoc data querying process is slow and error prone due to inability of health professionals to access data directly without involving IT experts. The problem lies in the complexity of means used to query data. We propose a new natural language- and star ontology-based ad-hoc data querying approach which reduces the steep …
Implementing cloud ERP solutions: a review of sociotechnical concerns
2018
Abstract Cloud ERP solutions allow organizations of all sizes to support and coordinate key business processes by leveraging virtualization. Nevertheless, the implementation of cloud ERPs is not straightforward and there are significant issues that need to be taken into account when launching cloud ERP initiatives. To explore these issues, we conducted an in-depth systematic review of related research literature. We identified six key issues related to cloud ERP implementation: a) functionality fit, b) integration, c) data migration, d) organizational change, e) data security, and f) reliability. Furthermore, we mapped these issues to the different sizes of organizations. Based on this revi…
Cárcavas y regueros generados en suelos sódicos : Petrer (Alicante, España)
2013
Este articulo pretende mostrar las interacciones entre los procesos de piping y la formacion de carcavas y regueros en diferentes sub-sistemas (laderas y rellenos de fondo de valle) de una pequena cuenca del SE espanol. Se analiza la influencia de diversas propiedades del los suelos y regolitos en el desarrollo de formas asociadas al piping. Los sistemas reguero-tunel de las laderas de badlands estan principalmente relacionados con la ratio de absorcion de sodio (SAR) y la conductividad electrica (CE) de los suelos. En contraste, en los rellenos de fondo de valle estas propiedades quimicas interactuan con las discontinuidades en el gradiente hidraulico introducidas por las terrazas de culti…
JEM–X science analysis software
2003
The science analysis of the data from JEM-X on INTEGRAL is performed through a number of levels including corrections, good time selection, imaging and source finding, spectrum and light-curve extraction. These levels consist of individual executables and the running of the complete analysis is controlled by a script where parameters for detailed settings are introduced. The end products are FITS files with a format compatible with standard analysis packages such as XSPEC. Martinez Nuñez, Silvia, Silvia.Martinez@uv.es
Diffuse and focused carbon dioxide and methane emissions from the Sousaki geothermal system, Greece
2006
[1] We report first data on chemical composition of the gas emitted by the geothermal system of Sousaki, Greece. Gas manifestations display typical geothermal gas composition with CO2 as the main component and CH4 and H2S as minor species. Soil gas composition derives from the mixing of two end-members (atmospheric air and geothermal gas). Soil CO2 fluxes range from<2 to 33,400 g m−2 d−1. The estimated diffuse output of hydrothermal CO2, estimated for an area of 0.015 km2, is about 630 g s−1, while a tentative estimation of CH4 diffuse output gave a value of about 1.15 g s−1. Point sources accounted for lower flux values of ∼26 g s−1 of CO2, ∼0.1 g s−1 of CH4 and ∼0.02 g s−1 of H2S.
Fire effects on soil aggregation: A review
2011
Abstract Fire can affect soil properties depending on a number of factors including fire severity and soil type. Aggregate stability (AS) refers to soil structure resilience in response to external mechanical forces. Many authors consider soil aggregation to be a parameter reflecting soil health, as it depends on chemical, physical and biological factors. The response of AS to forest fires is complex, since it depends on how fire has affected other related properties such as organic matter content, soil microbiology, water repellency and soil mineralogy. Opinions differ concerning the effect of fire on AS. Some authors have observed a decrease in AS in soils affected by intense wildfire or …
The multidisciplinary origin of soil geography: A review
2018
Abstract Soil geography should be clearly recognized as a sub-discipline of physical geography and soil science, but at various times over the last century it was accepted as a complementary and descriptive sub-discipline of botany, agronomy and geology. In other words, there was not a clear consensus about its definition and origins. The main goal of this paper is to conduct a historical review (s. XX-XXI) of soil geography to clarify its origin, early methods, first authors and the importance of its interdisciplinary perspective within the scientific community. We found that soil geography was considerably advanced by the work of K.D. Glinka (1867–1927), one of Dokuchaev's students, who c…
Monitoring desertification and land degradation over sub-Saharan Africa
2004
A desertification monitoring system is developed that uses four indicators derived using continental-scale remotely sensed data: vegetation cover, rain use efficiency (RUE), surface run-off and soil erosion. These indicators were calculated on a dekadal time step for 1996. Vegetation cover was estimated using the Normalized Difference Vegetation Index (NDVI). The estimation of RUE also employed NDVI and, in addition, rainfall derived from Meteosat cold cloud duration data. Surface run-off was modelled using the Soil Conservation Service (SCS) model parametrized using the rainfall estimates, vegetation cover, land cover, and digital soil maps. Soil erosion, one of the most indicative paramet…
Influence of environmental factors on the spatial distribution and diversity of forest soil in Latvia
2012
This study was carried out to determine the spatial relationships between environmental factors (Quaternary deposits, topographical situation, land cover, forest site types, tree species, soil texture) and soil groups, and their prefix qualifiers (according to the international Food and Agricultural Organization soil classification system World Reference Base for Soil Resources [FAO WRB]). The results show that it is possible to establish relationships between the distribution of environmental factors and soil groups by applying the generalized linear models in data statistical analysis, using the R 2.11.1 software for processing data from 113 sampling plots throughout the forest terri…
