Ruolo e limiti del contratto negli assetti familiari in funzione successoria

The Article 457 c.c. expressly excludes the contract by the sources of the succession. Moreover, the article 458 c.c., apart from the initial brief aside dedicated to the institute of the family pact, agrees nullity of the agreements with whom someone decides its own succession as well as those with which the future successor could decide about his rights or renounce to them about a succession not yet open. However, for a long time, the Italian doctrine wonders about the role of the contract within the succession law. It feels, in fact, the need to expand the private autonomy within the inheritance that is excessively sacrificed by the prohibition of succession agreements and by the norms for the protection of legitimate heirs. The reasons which led the legal science to these conclusions are based on different events, both social and economic, that push the interpreter to a modernization of dogmatic categories with which he can represent the succession mortis causa. In addiction, it is necessary to underline the crisis of the agreements mortis causa due to this economical and social events: as a matter of fact, the will, as the only way to give the assets post mortem, revealed itself incomplete and extremely severe compared to the new social needs. In fact, increasingly the way to give the assets happens out of the inheritance and despite to the institutions designed by the law. For these reasons, in order to adapt the system of succession to modern economic and social needs, the doctrine has identified, within the system, institutions of a contractual nature in order to better achieve the interests of private, obviating the limits assigned to the shop last will. And recently, in this context, our legislator has introduced the institution of the family pact (art. 768 bis et seq. c.c.), that is the agreement through “the entrepreneur transfers, in whole or in part , the company, and the holder of equity investments transfers, in whole or in part, its shares, to one or more descendants". While, however, part of the doctrine encourages the provision of tools that enable a person to have in advance of his succession, on the other hand there are those who promote the centrality of the will within our legal system and calls for the revitalization in respect of its vast potential is not always adequately exploited. This research aims to verify whether the contract can find importance within the phenomenon of succession for the inter vivos transfer of family assets and if the same has the characteristics to be considered a working alternative to the will. In the present work will be analyzed, in addition, some of the institutions that the doctrine has considered alternatives to the will and particularly the institution of the family pact. The survey will also be directed to the limits that the private autonomy and the legislator met in the use of the contractual instrument, limits that are mostly originated by the rules and principles of the law of succession.

Fertilización o reemplazo de especies : revisión bibliográfica de los efectos sobre la productividad del pastizal natural

Los pastizales son los ecosistemas terrestres más extensos que existen en el mundo y se estima que ocupan un área de 52,2 millones de kilómetros cuadrados. Su productividad primaria neta aérea (PPNA) es una propiedad fundamental ya que determina la cantidad de energía que se encuentra disponible para otros niveles tróficos y está controlada por la calidad del suelo y la cantidad el agua. Suele intervenirse el pastizal para lograr diversos objetivos, tales como, aumentar y concentrar o distribuir la PPNA durante el año y aumentar la calidad forrajera de las especies que lo componen. Este trabajo tiene por objetivo responder a dos cuestiones inherentes a la productividad primaria neta de los pastizales: la primera es evaluar el impacto de la fertilización sobre la producción de los pastizales con Nitrógeno (N), Fósforo (P) y ambos (N+P). Y la segunda es evaluar el efecto sobre la producción de biomasa aérea del reemplazo de las comunidades originales del pastizal por una o varias especies forrajeras, las cuales pueden ser exóticas o naturalizadas. Para conseguir estos objetivos se realizó una revisión bibliográfica y un análisis de los datos cuantitativos publicados en diferentes revistas científicas y técnicas con y sin referato. La productividad de los tratamientos de corrección de la fertilidad edáfica con N; N+P y P se diferenciaron estadísticamente (p menor a 0,0001) de la producción del pastizal natural. Al analizar, en promedio, el incremento de biomasa producido se destaca en primer lugar el tratamiento N+P con 1825 kg MS/ha/año, le sigue el tratamiento con N con 768 kg MS/ha/año y en último lugar es el tratamiento P con 531 kg MS/ha/año. En el rango de precipitación entre los 800 y 1.140 mm, similar a los de la región pampeana, la PPNA de las pasturas implantadas se diferenció estadísticamente, (p menor a 0,0001), mediante una prueba t, de la PPNA de los pastizales. La media de producción de los pastizales fue de 3.933 kg MS/ha/año y de las pasturas fue de 5.763 kg MS/ha/año. En la mayoría de los ensayos la productividad de la pastura bajo la misma precipitación fue superior a la del pastizal.

Correlation of solder paste rheology with computational simulations of the stencil printing process

Soldering technologies continue to evolve to meet the demands of the continuous miniaturisation of electronic products, particularly in the area of solder paste formulations used in the reflow soldering of surface mount devices. Stencil printing continues to be a leading process used for the deposition of solder paste onto printed circuit boards (PCBs) in the volume production of electronic assemblies, despite problems in achieving a consistent print quality at an ultra-fine pitch. In order to eliminate these defects a good understanding of the processes involved in printing is important. Computational simulations may complement experimental print trials and paste characterisation studies, and provide an extra dimension to the understanding of the process. The characteristics and flow properties of solder pastes depend primarily on their chemical and physical composition and good material property data is essential for meaningful results to be obtained by computational simulation.This paper describes paste characterisation and computational simulation studies that have been undertaken through the collaboration of the School of Aeronautical, Mechanical and Manufacturing Engineering at Salford University and the Centre for Numerical Modelling and Process Analysis at the University of Greenwich. The rheological profile of two different paste formulations (lead and lead-free) for sub 100 micron flip-chip devices are tested and applied to computational simulations of their flow behaviour during the printing process.

Mixed-Function Oxygenases And Xenobiotic Detoxication-Toxication Systems In Bivalve Mollusks

Components of a xenobiotic detoxication/toxication system involving mixed function oxygenases are present inMytilus edulis. Our paper critically reviews the recent literature on this topic which reported the apparent absence of such a system in bivalve molluscs and attempts to reconcile this viewpoint with our own findings on NADPH neotetrazolium reductase, glucose-6-phosphate dehydrogenase, aldrin epoxidation and other reports of the presence of mixed function oxygenases. New experimental data are presented which indicate that some elements of the detoxication/toxication system inM. edulis can be induced by aromatic hydrocarbons derived from crude oil. This includes a brief review of the results of long-term experiments in which mussels were exposed to low concentrations of the water accommodated fraction of North Sea crude oil (7.7–68 µg 1−1) in which general stress responses such as reduced physiological scope for growth, cytotoxic damage to lysosomal integrity and cellular damage are considered as characteristics of the general stress syndrome induced by the toxic action of the xenobiotics. In addition, induction in the blood cells of microsomal NADPH neotetrazolium reductase (associated with mixed function oxygenases) and the NADPH generating enzyme glucose-6-phosphate dehydrogenase are considered to be specific biological responses to the presence of aromatic hydrocarbons. The consequences of this detoxication/toxication system forMytilus edulis are discussed in terms of the formation of toxic electrophilic intermediate metabolites which are highly reactive and can combine with DNA, RNA and proteins with subsequent damage to these cellular constituents. Implications for neoplasms associated with the blood cells are also discussed. Finally, in view of the increased use of mussel species in pollutant monitoring programmes, the induction phenomenon which is associated with microsomal enzymes in the blood cells is considered as a possible tool for the detection of the biological effects of environmental contamination by low concentrations of certain groups of organic xenobiotics.
