Hepatocyte transplantation, a step forward?
2019
Hepatocyte transplantation emerged a few decades ago as a possible strategy to overcome some of the limitations of liver transplantation, among them the availability of organ donors and the functional quality of grafts. Nowadays, allogenic cell transplantation is still to be confirmed as a viable therapeutic option for patients with hereditary metabolic liver diseases. Although we have now overseen 5 decades of basic and animal research in the field, the number of successfully treated patients remains low. Limitations in cell engraftment and selective proliferation of transplanted cells remain a constraint to the generalized use of this therapeutic approach.
Automatic surrogate modelling technique selection based on features of optimization problems
2019
A typical scenario when solving industrial single or multiobjective optimization problems is that no explicit formulation of the problem is available. Instead, a dataset containing vectors of decision variables together with their objective function value(s) is given and a surrogate model (or metamodel) is build from the data and used for optimization and decision-making. This data-driven optimization process strongly depends on the ability of the surrogate model to predict the objective value of decision variables not present in the original dataset. Therefore, the choice of surrogate modelling technique is crucial. While many surrogate modelling techniques have been discussed in the liter…
Monitoraggio e percezione delle esperienze formative internazionali tra gli specializzandi italiani in igiene e medicina preventiva. Indagine condott…
2013
Introduzione Molti studi hanno dimostrato che le esperienze formative internazionali (International Health Electives - IHE) contribuiscono all'acquisizione di conoscenze e competenze fondamentali per i futuri professionisti in Sanità proprio attraverso l'opportunità di confronto fra sistemi sanitari e contesti socio-culturali differenti. Sebbene le IHE siano in crescita, non ci sono dati che riguardino quelle svolte dagli specializzandi italiani in Igiene. L'obiettivo dello studio è di raccogliere informazioni sulle loro pregresse esperienze formative internazionali e di comprendere motivazioni ed eventuali criticità relative alla decisione di effettuare una IHE. Materiali e metodi Gli spec…

Limits to CO2-Neutrality of Burning Wood. (Review)
2016
Abstract Consumption of wood as a source of energy is discussed with respect to efficiency and restraints to ensure sustainability of the environment on the grounds of a simple analytical model describing dynamics of biomass accumulation in forest stands – a particular case of the well-known empirical Richards’ equation. Amounts of wood harvested under conditions of maximum productivity of forest land are presented in units normalised with respect to the maximum of the mean annual increment and used to determine the limits of CO2-neutrality. The ecological “footprint” defined by the area of growing stands necessary to absorb the excess amount of CO2 annually released from burning biomass is…
Territorial Intelligence and Governance.
2007
International audience; As with European experiments, in various regions in France, territorial intelligence projects have been initiated since 2003. (see the regions of Lower Normandy, Lorraine, Réunion Island, the Aquitaine region, etc.).The objective of these is to gather and exploit information which is not confined to particular sectors and the collective processing of which can contribute to durable development. Apart from institutions, civil society and the inhabitants of the territory, it is observed that companies and in particular small and medium sized enterprises are natural partners who show interest in such initiatives. Both the different economic chains and the participating …
EFFICACIA DI DISPOSITIVI FORMATIVI ELABORATIVO-RIFLESSIVI IN INTERVENTI ORIENTATI ALLO SVILUPPO DELL’IDENTITÀ PROFESSIONALE IN STUDENTI
2013
Introduzione. All’interno di un progetto relativo alla costruzione di un modello psicosociale della qualità universitaria, il contributo si centra sulla verifica di efficacia di dispositivi formativi riflessivi atti a consentire agli studenti il riconoscimento e lo sviluppo virtuoso dei loro modelli di identità, così da facilitare la costruzione di rappresentazioni di ruolo sulle quali fondare competenze idonee a dialogare con la mutevolezza, ormai strutturale, dei contesti e degli utenti delle professioni di aiuto. Obiettivi e metodi I dispositivi utilizzati, gruppi semi-direttivi di discussione, sono stati finalizzati alla esplorazione e trasformazione in chiave meno idealizzante delle ra…
Control of the Development of Swirling Airflow Dynamics and Its Impact on Biomass Combustion Characteristics
2017
Abstract The development of the swirling flame flow field and gasification/ combustion dynamics at thermo-chemical conversion of biomass pellets has experimentally been studied using a pilot device, which combines a biomass gasifier and combustor by varying the inlet conditions of the fuel-air mixture into the combustor. Experimental modelling of the formation of the cold nonreacting swirling airflow field above the inlet nozzle of the combustor and the upstream flow formation below the inlet nozzle has been carried out to assess the influence of the inlet nozzle diameter, as well primary and secondary air supply rates on the upstream flow formation and air swirl intensity, which is highly …
Improving Energy Expenditure Estimation in Wrist-Worn Wearables by Augmenting Heart Rate Data With Heat Flux Measurement
2021
Wearable electronics are often used for estimating the energy expenditure of the user based on heart rate measurement. While heart rate is a good predictor of calorie consumption at high intensities, it is less precise at low intensity levels, which translates into inaccurate results when estimating daily net energy expenditure. In this study, heart rate measurement was augmented with heat flux (HF) measurement, a form of direct calorimetry. A physical exercise test on a group of 15 people showed that HF measurement can improve the accuracy of calorie consumption estimates especially during rest and low-intensity activity when used in conjunction with heart rate information and vital backgr…
Kędzierzyn-Koźle – dziedzictwo przeszłości w kulturze miasta przemysłowego na pograniczu etniczno-kulturowym
2021
The article draws attention to the issues of symbolic functioning of the city which was formed of two different entities as a result of political and economic decisions. In the 20th century, the history of a traditional city got entwined with a modernistic industrial city which was taking shape. As a result, ideologies and politics impacted on the newly-established conurbation. The city denotes not only the material sphere, but also its urban community, which, in the case of the places under study, was basically historically complicated. The method of description is the ‘culturalistic’ orientation in the study of the city and also the (emotional) sociolog y of Silesia of the Rev. Emil Szram…
