Le parentele tra città in Tucidide
2012
Si esaminano i passi più significativi delle Storie di Tucidide in cui compaiono i termini di syngeneia e di oikeiotes per esprimere i rapporti di parentela tra città o popoli. Se ne ricava la conclusione che per lo storico ateniese i due termini avevano un'accezione differente, indicando il primo i rapporti tra genti ritenute discendenti dal medesimo capostipite mitico, e il secondo i rapporti di stretta familiarità stabiliti tra città di origine etnica differente, come nel caso di Camarina e Atene. Tucidide non rinnega il valore atavico della consanguineità ma mette in evidenza attraverso le scelte lessicali il carattere propagandistico di alcuni appelli alle parentele etniche sfruttati a…
Dye-tracer technique for rill flows by velocity profile measurements
2020
Abstract Water flow on hillslope soil surface supplies energy which is required to detach soil particles, to transport and deposit sediments, therefore flow velocity is a key variable related to hillslope hydrodinamics of soil erosion processes. Among the different methods available for measuring velocity of shallow interrill and rill flow, the trace technique is widely used. Trace technique is applied by adding a material (salt, magnetic material, water isotope, floating object) and then measuring the speed of the material to travel a known distance from the injection point. When flow velocity is measured using a dye-tracing method, the mean velocity is calculated by multiplying the measur…
Flume experiments for assessing the dye-tracing technique in rill flows
2021
Abstract Flow velocity controls hillslope soil erosion and is a key hydrodynamic variable involved in sediment transport and deposition processes. The dye-tracer technique is one of the most applied methods for measuring velocity of shallow interrill and rill flow. The technique is based on the injection of a tracer in a specific point and the measurement of its speed to travel the known distance from the injection point to a given channel section. The dye-tracer technique requires that the measured surface flow velocity has to be corrected to obtain the mean flow velocity using a correction factor which is generally empirically deduced. The technique has two sources of uncertainties: i) th…
Validación de Procedimientos Poblacionales mediante Convolución para el Establecimiento de Correlaciones In Vitro-In Vivo
2018
Para desarrollar medicamentos que sean efectivos y seguros es necesario conocer su comportamiento tanto in vitro como in vivo. Uno de los desafíos en la investigación biofarmacéutica es correlacionar la información de liberación in vitro de un fármaco con los perfiles plasmáticos in vivo. Por lo tanto, durante los últimos años se ha incrementado el uso de modelos matemáticos que sean capaces de predecir el comportamiento in vivo de un fármaco a través de los datos de disolución in vitro, es decir, correlaciones in vitro - in vivo (IVIVC). Las IVIVC pueden acortar la duración del desarrollo de los medicamentos, así como reducir el gasto y mejorar la calidad del producto. El principal objetiv…
Quantitative analysis of mixtures of metal-carbonyl complexes by Fourier-transform infrared spectroscopy: application to the simultaneous double immu…
1996
Abstract The feasibility of a double immunoassay of haptens by the nonisotopic carbonyl metalloimmunoassay (CMIA) method is demonstrated. Three different pairings of antiepileptic medications from the groups carbamazepine, diphenylhydantoin, and phenobarbital (for each of which a mono-CMIA is already available) were assayed by double CMIA. The assay method employs as tracers metal–carbonyl complexes that give very strong signals in the range of 1850–2200 cm −1 in the infrared spectrum, permitting quantitative analysis by Fourier-transform infrared spectroscopy. The fact that the signals are individually assignable and of comparable intensity permits quantitative analysis of mixtures of two …
Il progetto di interni come architettura della post-production
2014
Il saggio descrive le metodologie, gli obbiettivi e le pratiche didattiche del progetto di interni, nella didattica dell'architettura dal 3° anno. Esso esplora alcune linee di ricerca che riguardano la trasformazione dello spazio costruito a partire dal suo nocciolo interno e guarda alla nozione di Nicolas Bourriaud della post- production come nuovo paradigma possibile per l'architettura e le sue trasformazioni contemporanee.
Application of multivariate analysis techniques for selecting soil physical quality indicators: A case study in long-term field experiments in Apulia…
2019
Long-term field experiments and multivariate analysis techniques represent research tools that may improve our knowledge on soil physical quality (SPQ) assessment. These techniques allow us to measure relatively stable soil conditions and to improve soil quality judgment, thereby reducing uncertainties. A monitoring of SPQ under long-term experiments, aimed at comparing crop residue management strategies (burning vs. incorporation of straw, FE1) and soil management (minimum tillage vs. no tillage, FE2), was established during the crop growing season of durum wheat. The relationships between five SPQ indicators (bulk density [BD], macroporosity [PMAC], air capacity [AC], plant available wate…
Producción de personas, reproducción de representaciones. Reflexiones sobre dos programas de capacitación en liderazgo
2020
The present paper addresses the question of the role Executive Education performs in the strengthening and reproduction of neoliberal ideology. It aims to critically reflect on the way selected contents and teaching activities operate jointly enabling or inhibiting certain perspectives regarding work in organizations. Two Leadership training programs are analyzed in this article, currently delivered by the two most prestigious business schools in Argentina: IAE Business School, and Torcuato Di Tella Business School. I begin with a general description of each one and proceed analyzing their educational proposals. Finally, the critical review reveals their consistency with a set of social rep…
Dislipidēmija kā riska faktors nieru funkcionālo spēju samazinājumam I tipa cukura diabēta pacientiem
2019
Diabētiskā nefropātija ir svarīga un bieži diabēta pacienta dzīvību apdraudoša mikrovaskulāra komplikācija (Groop et al., 2009). Diabētiskās nefropātijas pacientiem dislipidēmiju sastop bieži, tomēr līdz šim veikto pētījumu rezultāti nav viennozīmīgi attiecībā uz seruma lipīdu frakciju ietekmi uz nieru funkciju. Pētījuma mērķis bija izpētīt 1. tipa cukura diabēta pacientu lipīdu un apolipoproteīnu līmeņu asociāciju ar nieru funkcionālo spēju (glomerulārā filtrācijas ātruma un albuminūrijas) samazinājumu laika gaitā. Veikts šķērsgriezuma tipa pētījums, kurā tika izmantoti 106 1. tipa cukura diabēta pacientu paraugi un klīniskie dati no „LatDiane: Latvijas diabētiskās nefropātijas pētījuma”, …
NT-pro-BNP nozīme agrīnā HSM diagnostikā 2. tipa cukura diabēta pacientiem
2020
Ievads. Pacientiem ar otrā tipa cukura diabētu ir ievērojami lielāks risks attīstīties kardiovaskulārai slimībai. Lielai daļai pacientu ar otrā tipa diabētu var attīstīties kardiovaksulāra saslimšana bez tipiskas klīniskās ainas, kā rezultātā kardiovaskulāru slimību diagnosticē novēloti, kad tā jau ir progresējusi. Līdz ar to būtu svarīgi šiem pacientiem veikt skrīningu, lai priekšlaicīgi diagnosticētu vai novērstu kardiovaskulāru slimību attīstību – noteikt NT-pro-BNP. Pētījuma mērķis. Pētīt NT-pro-BNP izmaiņas otrā tipa cukura diabēta pacientiem, kuriem slimības vēsturē nav kardiovaskulāru saslimšanu, un vai NT-pro-BNP līmenim asinīs ir saistība pacienta dzimumu, vecumu un slimošanas ar o…
