Kant and Goethe

1972

In this paper we want to consider the inner connection between Kant and Goethe; therefore we want to emphasize primarily aspects they have in common rather than points of opposition. Goethe says for example about Kant’s Critique of Pure Reason that this “voice has brought a great advancement,” in so far as through it man has been able “to awaken concerning himself,” concerning his “highest faculty of reason.” Goethe was above all impressed, however, by the Critique of Judgment and he confessed: “The great main ideas of this work were analogous to my own previous ideas.” It was for him “an exceedingly great deed... that Kant placed art and nature in his Critique of Judgment side by side” so …

Biobased Epoxy Resin by Electrochemical Modification of Tall Oil Fatty Acids

2019

A biobased epoxy resin was prepared from tall oil fatty acids (TOFAs), a byproduct of the pulping industry. As free carboxylic acids compromise resin stability, TOFA was subjected to non-Kolbe decarboxylation to give alkenes upon loss of CO2. Thereby, the degree of unsaturation is significantly increased. This electrosynthetic protocol using an undivided cell setup and inexpensive graphite electrodes in a galvanostatic operation mode was scaled to a 1.5 L reactor, making use of electric current as a green and waste-free reagent. Simple, cost-efficient epoxidation using oxone subsequently gives an epoxy resin of low viscosity. Curing with anhydrides yields thermoset materials. Dynamic mechan…

Preliminary studies about thermal degradation of edible oils through attenuated total reflectance mid-infrared spectrometry

2009

Abstract Degradation of edible oils during their heating process has been evaluated through the determination of cis -unsaturation and trans -fatty acids together with free fatty acids as a function of time and temperature heating. Two types of cooking oils, sunflower and seed (mixture of different seeds non-detailed), were heated at three different temperatures (147, 171 and 189 °C) during a total time of 1920 min (32 h) shared out in four sessions of 8 h each one, and samples were studied from their spectra obtained by Fourier transform infrared spectrometry using attenuated total reflectance measurements. A critical comparison between different multivariate calibration models built based…

dSDiVN: A Distributed Software-Defined Networking Architecture for Infrastructure-Less Vehicular Networks

2017

In the last few years, the emerging network architecture paradigm of Software-Defined Networking (SDN), has become one of the most important technology to manage large scale networks such as Vehicular Ad-hoc Networks (VANETs). Recently, several works have shown interest in the use of SDN paradigm in VANETs. SDN brings flexibility, scalability and management facility to current VANETs. However, almost all of proposed Software-Defined VANET (SDVN) architectures are infrastructure-based. This paper will focus on how to enable SDN in infrastructure-less vehicular environments. For this aim, we propose a novel distributed SDN-based architecture for uncovered infrastructure-less vehicular scenari…

Review of information and communication technologies for smart micro-grid automation

2017

The growing challenges of Smart Micro-Grid can only be met if secure and fast information and communication technology (ICT) solutions are developed. In this paper, some of the ICT techniques are reviewed for smart micro-grid automation. Firstly, an overview of the role of ICT in grid distribution is explained with respect to electricity value chain in power distribution. Further, each domain in the value chain is analyzed with respect to ICT applications in power generation, transmission, distribution and consumption. ICT stands as a prominent driving force to enhance trustworthiness, security, and productivity of the power distribution through information exchange, regulated generation, d…

Impact of Demand Response Control Logic on Isolated Island's Distribution Networks

2019

The work presents the results of a study regarding the impact of some Demand Response control logics on an isolated distribution network. The proposed control is divided into precise steps in which the coordination between the general aggregator controller and the single local Energy Management Systems is developed and illustrated with details. The control is applied to the flexible loads and to the storage systems of photovoltaic plants installed at the end-users' houses and connected to the network. The study is carried out delivering a suitable network model of the island's system, with the implementation of load profiles for all the loads of the network for a total simulation time of 24…

Effects of Demand Side Management on the Operation of an Isolated LV Microgrids

2019

The work presents the results of a study regarding the impact of Demand Side Management actions on flexible loads distributed at the domestic end-users' facilities in an isolated low voltage microgrid. Aim of the research study is to evaluate how the implementation of local control actions on the end-user's side can impact on the operation of the isolated microgrid. The Demand Side Management is applied by each domestic user to optimize the operation of its own resources following well-defined operative steps. The study is carried out implementing a suitable model of the microgrid in Neplan environment, while the daily controlled load profiles of the end-users are evaluated using the Montec…

Revisión del sistema pronominal español

2002

This article offers a critical review of the Spanish pronominal system (personal, possessive and demonstrative pronouns) as described in Nebrija's works and in those of the 16th and 17th century grammarians. These texts show that the history of grammatics is frequently a history of errors. In fact, the methodology conveniences they chose to establish regular models, led grammarians to false the reality of the language. Quite frequently also, as they intended to develop the grammatical thinking establishing certain categories or divisions among them, these authors originated errors that have been perpetuated in their texts. From my point of view, that is the case for pronouns. As has been de…

Selective Sacral Nerve Blockade for the Treatment of Unstable Bladders

1987

38 patients with severe urge or urge incontinence, who did not respond to conservative therapy, were treated with selective sacral nerve blockade using a local anesthetic (bupivacaine). 6 patients of this group had definite selective sacral denervation with phenol. In 31 patients a urodynamic study was done previous to the sacral nerve block as well as 10 and 90 min after the injection. Within the first 2-7 weeks the success rate was about 70% in regard to bladder capacity and mean volume at first desire to void. On long-term follow-up (greater than 7 months), the success rate decreased to about 16%. Only 1 patient of the phenol group still has complete detrusor areflexia for now more than …
