Considering syntrophic acetate oxidation and ionic strength improves the performance of models for food waste anaerobic digestion.
2021
Current mechanistic anaerobic digestion (AD) models cannot accurately represent the underlying processes occurring during food waste (FW) AD. This work presents an update of the Anaerobic Digestion Model no. 1 (ADM1) to provide accurate estimations of free ammonia concentrations and related inhibition thresholds, and model syntrophic acetate oxidation as acetate-consuming pathway. A modified Davies equation predicted NH3 concentrations and pH more accurately, and better estimated associated inhibitory limits. Sensitivity analysis results showed the importance of accurate disintegration kinetics and volumetric mass transfer coefficients, as well as volatile fatty acids (VFAs) and hydrogen up…

La objeción de conciencia sanitaria en el ámbito penitenciario
2010
Lo mas coherente con la doctrina constitucional es concebir la objecion de conciencia como una manifestacion del derecho fundamental a la libertad ideologica del art. 16.1 CE (asumiendo, por tanto, la legitimidad de toda conducta objetora), pero entendida como un principio; es decir: cualquier conflicto entre el derecho fundamental del sujeto y el deber juridico que se rehusa debe ser resuelto por el juez realizando un juicio ponderativo de bienes y valores. Este derecho fundamental persiste y puede ser invocado y ejercido por reclusos y personal sanitario en el contexto penitenciario, frente a las previsiones de imposicion coactiva de tratamientos medico previstas por la LOGP y el RP, sin …
Isobaric Vapor−Liquid Equilibria for Binary and Ternary Mixtures of Dipropyl Ether, 1-Propyl Alcohol, and Butyl Propionate
2006
Consistent vapor−liquid equilibrium (VLE) data at 101.3 kPa have been determined for the ternary system dipropyl ether + 1-propyl alcohol + butyl propionate and two constituent binary systems: dipropyl ether + butyl propionate and 1-propyl alcohol + butyl propionate. The dipropyl ether + butyl propionate system exhibits ideal behavior, and the 1-propyl alcohol + butyl propionate system shows positive deviations from Raoult's law. No additional azeotropes are present. The activity coefficients of the solutions were correlated with its composition by the Wilson, NRTL, and UNIQUAC models. The ternary system is well-predicted from binary interaction parameters. Butyl propionate breaks the dipr…
Die Synthese vono-Acylamino-β-dimethylamino-propiophenonen. 4. Mitt.: Synthese der primären Mannich-Basen
1972
Das durch Umsetzung von 2-Acetamino-β-dimethylamino-propiophenon (IVb) mit Dibenzylamin darstellbare 2-Acetamino-β-dibenzylamino-propiophenon (XXVII) kann hydrogenolytisch mit tels Palladium-Aktivkohle in die entsprechende, nur am aromatischen Stickstoff acetylierte primare Mannich-Base ubergefuhrt werden. In analoger Weise sind auch in 5-Stellung substituierte Derivate des 2-Acetamino-β-amino-propiophenons (XXVIII) zuganglich. Synthesis of 2-Acylamino-β-amino-propiophenones 2-Acetamino-β-dibenzylamino-propiophenone (XXVII) and its derivatives, substituted in 5-position, can be synthetized by reaction of 2-acetamino-β-dimethylamino-propiophenone (IVb) with dibenzylamine. By hydrogenolysis i…
Transition from Youth categories to Elite cycling: relationships between early career performance and UCI World Tour success
2021
BACKGROUND The present study aimed to describe the possible roles of cyclists' early career performance, on the transition process to elite cycling categories. METHODS Data from national and international databases, and results achieved during the UCI World Championships, were retrospectively analysed considering the Italian national Youth-U16, Junior-U18, and U23 categories, and international Junior-U18 and UCI World-Tour categories. RESULTS The 15% of Youth-U16, the 38.8% of Junior-U18 and the 60% of U23 athletes who ranked top-10 between 2007 and 2013, scored points in UCI World Tour competitions between 2012 and 2018. The 1.6% of Youth-U16, the 8.3% of Junior-U18 and 25% of U23 athletes…

δ 1‐OPIOID receptor‐mediated controlofacetylcholine (ACh) release in human neocortex slices
1998
In slices of human neocortex, prelabelled with [3H]-choline, the release of [3H]-acetylcholine reflects the evoked release of endogenous acetylcholine which was elicited by the same electrical stimulation paradigm. [3H]-Acetylcholine release was depressed by the delta-opioid receptor agonist D-Pen2-D-Pen5-enkephalin. When the nerve endings were depolarized by elevating extracellular potassium the evoked [3H]-acetylcholine release was similarly depressed by D-Pen2-D-Pen5-enkephalin in the absence, but not in the presence, of tetrodotoxin which blocks action potential propagation. Therefore, the delta-opioid receptor inhibiting [3H]-acetylcholine release should not be located to cholinergic n…
Lack of plasmic beta-endorphin response to a gastronomic meal in healthy humans.
1991
Abstract In order to study the relationship between the endogenous opiate system and food intake in man, plasma concentrations of beta-endorphin were measured in ten healthy subjects. Time course of beta-endorphinemia was compared under the following conditions: basal (fasting), after an injection of pentagastrin (6 μg/kg), or after a gastronomic meal. No changes in plasma beta-endorphin or ACTH concentrations were observed with pentagastrin nor after the meal, despite the combination of very high sensory pleasure with intake of a very large amount of food. It is concluded that blood beta-endorphin concentration is not a sensitive index of the effects of food intake on the endogenous opioid…
Influence of glucose control and improvement of insulin resistance on microvascular blood flow and endothelial function in patients with diabetes mel…
2005
The study was performed to investigate the effect of improving metabolic control with pioglitazone in comparison to glimepiride on microvascular function in patients with diabetes mellitus type 2.A total of 179 patients were recruited and randomly assigned to one treatment group. Metabolic control (HbA1c), insulin resistance (HOMA index), and microvascular function (laser Doppler fluxmetry) were observed at baseline and after 3 and 6 months.HbA1c improved in both treatment arms (pioglitazone: 7.52 +/- 0.85% to 6.71 +/- 0.89%, p.0001; glimepiride: 7.44 +/- 0.89% to 6.83 +/- 0.85%, p.0001). Insulin-resistance decreased significantly in the pioglitazone group (6.15 +/- 4.05 to 3.85 +/- 1.92, p…
