„Bhagavad-Gītā, and the Universal Wisdom of Hinduism”
2020
Abstract The brief episode represented by the Bhagavad-Gītā, entrenched in the great body of the epic Hindu poem Mahābhārata, is revealing for the long lasting intellectual and spiritual effort made by the enlightened Indian philosophers in order to over-pass the ritual and social constraints put in place by the Veda, during the early period of the Hindu tradition. By focusing on the dialogue between a valiant knight and the earthly incarnation of God himself, a perennial wisdom is to be noticed. This is a promise for salvation from fear and death for all who dare to follow their duty, by offering them other ways of attending the Supreme. The self-sacrifice, the renunciation to all ego and …
Polymer-metal plasmonic waveguide : passive and active components for integrated photonics
2009
Dielectric loaded surface plasmon polariton waveguides (DLSPPWs) enable transmission at a sub-wavelength scale of both electrical and plasmonic (optical waves at the interface between a metal and a dielectric) signals in the same circuitry. Moreover, the use of a polymer as the dielectric load enables the functionalization of DLSPPWs. Therefore, this configuration is of great interest for integrated photonic applications. However, DLSPPWs suffer strong losses due to dissipation into the metal film. We address here the possibility of compensating the losses using a configuration analogous to an optical amplifier. We first set theoretical (effective index model), numerical (differential metho…
Pašbraucošu automašīnu algoritmu testēšanas iespējas autosacīkšu simulatoros
2020
Dažādi autovadītāju asistenti arvien vairāk iesaistās automašīnu vadīšanā. Pamazām parādās arī iebūvēti autopiloti, taču radīt pašbraucošas mašīnas ir ļoti dārgi un sarežģīti. Darbā tiks pētīts, kādus pašbraucošu automašīnu algoritmus un tehnoloģijas ir iespējams attīstīt uz autosacīkšu simulatoriem, izmantojot modificētas datora perifērijas ierīces un mikrokontrolierus. Algoritmu mērķis ir ne vien korekti veikt noteiktu maršrutu, bet arī spēt to izdarīt pēc iespējas ātrāk, maksimāli maz atpaliekot no cilvēka vadīta transporta. Algoritmus realizēs izmantojot mikrokontrolierus, kas pados signālus specializētām datorspēļu perifērijas ierīcēm, kas ar datoru sazināsies kā parasts datorspēļu kon…
DINAMICA DEI NITRATI E MINERALIZZAZIONE DEL CARBONIO IN UN SUOLO A VIGNETO IN AMBIENTE SEMIARIDO
2013
La gestione agronomica del vigneto in ambiente semiarido è spesso caratterizzata sia dalle frequenti lavorazioni del suolo che dall’apporto di fertilizzanti inorganici, in particolare azotati. Tale gestione, congiuntamente alle caratteristiche pedo-climatiche tipiche dell’ambiente semiarido, causa spesso un depauperamento del contenuto in sostanza organica del suolo e, dall’altro lato, incrementa il rischio di dilavamento di nitrati dal suolo. Al fine di controbilanciare tali effetti indesiderati, sono state introdotte nella gestione del suolo a vigneto tecniche di agricoltura conservativa, quali l’introduzione delle cover crops e l’interramento, previa trinciatura, dei residui di potatura,…
Engineered axon tracts within tubular biohybrid scaffolds
2021
[EN] Injuries to the nervous system that involve the disruption of axonal pathways are devastating to the individual and require specific tissue engineering strategies. Here we analyse a cells-biomaterials strategy to overcome the obstacles limiting axon regeneration in vivo, based on the combination of a hyaluronic acid (HA) single-channel tubular conduit filled with poly-L-lactide acid (PLA) fibres in its lumen, with pre-cultured Schwann cells (SCs) as cells supportive of axon extension. The HA conduit and PLA fibres sustain the proliferation of SC, which enhance axon growth acting as a feeder layer and growth factor pumps. The parallel unidirectional ensemble formed by PLA fibres and SC …
A semi-empirical approach for predicting two-phase flow discharge through branches of various orientations connected to a horizontal main pipe
2010
Abstract The subdivision of two-phase flow in branching conduits consisting of a large horizontal main pipe with upward, downward, or lateral branches of reduced diameter is of great interest in various technological fields. For example, these conduits are important in light-water nuclear reactors (LWRs) in the case of a small break loss-of-coolant accident (SBLOCA) in a leg of the reactor's primary coolant loops, as well as for breaks or valve malfunctions in a large pipeline. In these kinds of circumstances, the relevant phenomenology often involves phase stratification coupled with possible liquid entrainment or gas pool-through phenomena. Therefore, these phenomena were studied in depth…
Low-cost, portable open-source gas monitoring device based on chemosensory technology
2015
[EN] We report herein the construction of an electronic device to perform the real-time digitalization of the color state of the optical chemosensors used in the detection of dangerous gases. To construct the device, we used open-source modular electronics, such as Arduino and Sparkfun components, as well as free and open-source software (FOSS). The basic principle of the operation of this device is the continuous color measurement of a chemosensor-doped sensing film, whose color changes in the presence of a specific gas. The chemosensor-sensing film can be prepared by using any of the widely available chemosensors for the desired gas. Color measurement is taken by two TCS230 color sensor I…
Effects of PET packaging on the quality of an orange juice made from concentrate
2004
An orange juice made from concentrate was conditioned in three different PET (PolyEthylene Terephtalate) and glass packagings. Influence of storage conditions (length of storage, light, oxygen) on vitamin C content, browning index, and colour were measured. Results show that permeability to oxygen of PET packagings is the major factor detrimentally affecting the above parameters.
Effect of commercially available Plant Defence Stimulators (PDS) on human innate immunity
2014
PDS (Plant defence stimulators) constitute a recent alternative to pesticides used for crop protection. These compounds called elicitors are of diverse nature, but they all act by stimulating innate immune system of plants. So, plants can better fight pathogens. Furthermore, there are many similarities in pathogen perception systems and cellular signalling in plants and animals. It is well established that many elicitors stimulate both human and plant innate immunity (Zipfel and Felix, 2005). Therefore, it is likely that human innate immunity could be modulated by PDS. The aim of this study is to evaluate pro/anti-inflammatory activity of five different commercially available PDS on human c…
Les courses alimentaires à l'heure des drives : nouvelles pratiques, nouvelles mobilités ?
2017
Commerce et Changements Urbains, Paris, France, 18-/01/2017 - 20/01/2017; Avec le développement du commerce électronique, les pratiques d'achats des consommateurs et les infrastructures physiques du commerce de détail connaissent des transformations profondes, en particulier dans le domaine de l'alimentation. Même si le succès du e-commerce concerne d'autres produits, les achats alimentaires sont en progression : entre 2007 et 2011, la part des Français ayant acheté de la nourriture ou de l'épicerie sur Internet est passée de 3 % à un peu plus de 6 % (Gombault, 2013). Cette tendance s'accompagne d'une diversification des produits alimentaires disponibles sur Internet, du développement de no…
