This review details articles and recent patents in an emerging topic called powdered form of nano- and microparticles. Solid lipid particles were developed in the early 1990s and since, they have been considered as promising drug delivery systems, especially in providing a sustained release profile of the encapsulated drug. This kind of drug delivery system has several advantages, due to its physiological composition. It is generally well tolerated by the human body and are relatively stable during storage in comparison with other carriers like liposomes. The description of these powdered lipid particles, their different production processes and their applications are the focus of the article. [less ▲]

Ormerod and Mounfield [P. Ormerod, C. Mounfield, Power law distribution of duration and magnitude of recessions in capitalist economies: Breakdown of scaling, Physica A 293 (2001) 573] and Ausloos et al. [M. Ausloos, J. Mikievvicz, M. Sanglier, The durations of recession and prosperity: Does their distribution follow a power or an exponential law? Physica A 339 (2004) 548] have independently analyzed the duration of recessions for developed countries through the evolution of the GDP in different time windows. It was found that there is a power law governing the duration distribution. We have analyzed data collected from 19 Latin American countries in order to observe whether such results are valid or not for developing countries. The case of prosperity years is also discussed. We observe that the power law of recession time intervals, see Ref. [1], is valid for Latin American countries as well. Thus an interesting point is discovered: the same scaling time is found in the case of recessions for the three data sets (ca. 1 year), and this could represent a universal feature. Other time scale parameters differ significantly from each other. (C) 2008 Elsevier B.V. All rights reserved. [less ▲]

Up to now, self damping data generally comes from dynamic tests performed on test spans which length is of the order of some tens of meters. Those tests rely on the assumption that the conductor self damping changes the amplitude of incident and reflected travelling wave. In other words, there are no standing wave within a vibrating conductor and in practice, the amount of self damping is deduced from measurements of vibration amplitudes at adjacent “false vibration nodes”. The corresponding measurements require lots of dexterity and accuracy. This paper investigates the possibility of deducing the self damping properties of power line conductors from a series of tests performed quasi statically on a short prestressed conductor sample. Data recorded by Godinas [1] on 4 m long prestressed conductor samples has been used as an input (the conductors used are made of aluminium alloy, type AMS). This data was obtained by applying a cyclic quasi-static bending moment in the middle of the conductor sample and recording the corresponding strains. The experiment was reproduced at several prestress levels. A mining and analysis of this data has been performed so that in a first time the relationship between moment and curvature can be adequately defined. Then the corresponding internal work has been computed analytically (per integration). Finally a formulation for the self damping per unit length is proposed as a function of the antinode amplitude of vibration, frequency, conductor tension, bending stiffness, mass per unit length plus a special parameter called “b”. The latter parameter has the dimension of energy [J]. The corresponding results are found to be consistent with those deduced from the widely used “power law”, using Noiseux’s exponents [2, 3]. Also, a simplified version of the formula shows that the sensitivity of the self damping to the vibration amplitude, frequency and tension is comparable to that found by others authors using another self damping measurement technique [1], but with the difference that in this case, the exponents for frequency, amplitude and tension are integers, fully justified by the physics behind the phenomenon of damping.

The replacement and building of new electrical power lines (50 000 km in Europe) can’t cope with the growth of RES development in EU for the ten upcoming years. New solutions have to be found to manage such power transmission needs. Dynamic Line Rating (DLR) systems are part of the global solution. They allow to increase the power line capacity by an average 20% over the static rating (which is defined as the maximum current-carrying capacity as designed). The ampacity or thermal rating, is calculated thanks to (i) sensors installed directly on the power line conductors, like Ampacimon, (ii) weather data, and (iii) standard thermal models (IEEE, CIGRE). However, in order to be fully effective and to allow an efficient use of assets, ampacity calculation in real-time is not enough; it has to be forecasted as well. Beyond 6h-forecast, weather forecasts are necessary to compute the line ampacity up to two days ahead, as needed by network operation. As wind convection has a major impact on conductor cooling, even low wind speeds (2m/s up to 5m/s) allow a huge ampacity increase (the actual rating can be doubled). Therefore, low wind speed forecast up to 2-days ahead finds a major application in dynamic rating of overhead transmission and distribution lines. [less ▲]
