A concorrência no pensamento do professor Werter Rotunno Faria
No full textEste trabalho aborda o pensamento do Professor Werter Rotunno Faria acerca da concorrência - em especial, no que toca ao abuso do poder econômico, a apuração de ilicitude dos atos em virtude de seus efeitos, superando uma visão penalista existente - bem como da disciplina constitucional do mercado. Utiliza como fonte de pesquisa, na perquirição do tema, estudos doutrinários.This work brings up the thinking of Professor Werter Rotunno Faria in relation to competition - especially towards abuse of economic power, inquest of illegality of acts due to its effects, overcoming the existing penal view - as well as the constitutional discipline of the market. It uses his work as resource research, scrutinise the subject, doctrinaire studies

No full textFailure load of FRP strengthened masonry walls: experimental results and numerical models
No full textAim of the present work is the evaluation of the ultimate load bearing capacity of masonry panels reinforced with FRP strips. The investigation is developed performing both experimental and numerical studies. In particular, several panels subjected to different loading conditions are tested in the Tests Laboratory of the University of Florence (Italy). Then, numerical models based on combined homogenization and limit analysis techniques are proposed. The results obtained by numerical simulations are compared with experimental data. The good agreement obtained shows that the proposed numerical model can be applied for the evaluation of the ultimate load bearing capacity of reinforced masonry walls
Coprolites from rock shelters. Hunter-gatherers “Herding” Barbary sheep in the Early Holocene Sahara
No full textArchaeological deposits in rock shelters have enormous informative potential, particularly in arid environments where organic materials are well preserved. In these areas, sub-fossilized coprolites and dung remains have been identified as valuable proxies for inferences about past environments, subsistence economies and cultural trajectories. Here we present a multidisciplinary analysis of bovid (ovicaprine) coprolites collected from the Early Holocene hunter-gatherer occupation at Takarkori rock shelter (SW Libya, central Sahara). Our results show that Barbary sheep (Ammotragus lervia) were managed as early as ~9500 years calBP, mostly with the rearing of juveniles. Palynological analysis of individual pellets suggests a seasonal confinement of the animals and the selection of fodder. The analysis of coprolite distribution also indicates sophisticated strategies of Barbary sheep “herding” and spatial differentiation of specialized areas within the rock shelter, including the construction and use of a stone-based enclosure for corralling animals. These highly structured and organized forms of control over wild animals are interpreted as a potential co-evolutionary trigger for the subsequent rapid adoption and integration of the incoming pastoral Neolithic economy
Neutrino oscillations: A global analysis
No full textWe review the status of the neutrino oscillation physics (as of June 2003), with a particular emphasis on the present knowledge of the neutrino mass-mixing parameters in a three generation approach. We consider first the nu_mu-->nu_tau flavor transitions of atmospheric neutrinos. It is found that standard oscillations provide the best description of the SK+K2K data, and that the associated mass-mixing parameters are determined at 1 sigma (and dof=1) as: Delta m^2=(2.6 +-0.4) x 10^-3 eV^2 and sin^2(2theta)=1.00+0.00-0.05. Such indications, presently dominated by SK, could be strengthened by further K2K data. Then we analyze the energy spectrum of reactor neutrino events recently observed at KamLAND and combine them with solar and terrestrial neutrino data. We find that the solution to the solar neutrino problem at large mixing angle (LMA) is basically split into two sub-regions, that we denote as LMA-I and LMA-II. The LMA-I solution, characterized by lower values of the squared neutrino mass gap, is favored by the global data fit. Finally, we briefly illustrate how prospective data from the SNO and KamLAND can increase our confidence in the occurrence of standard matter effects in the Sun, which are starting to emerge from current data
Africa, North: Eastern Sahara
No full textThe Eastern Sahara is one of the best-known areas of North Africa when it comes to archaeological and geoarchaeological research. A fair amount is known about the region's past cultural and climatic developments. The present entry features some of the events related to Eastern Sahara's long term occupational history, stretching from early human settlement during the Early and Middle Stone Age to the last human settlement of the Aterian before the long late Pleistocene hiatus. At the beginning of the Holocene the desert transformed into a savannah thanks to the northward penetration of the monsoon. Following the greening of the Sahara, complex pottery producing hunter-gatherers thrived in the area, accompanied during the very beginning of the Middle Holocene by the development of animal husbandry and food producing Neolithic societies
