Apple tree production in Italy: rootstocks, cultivars, fertilization, and irrigation
Giovambattista Sorrenti,Adamo Domenico Rombolà,Giuseppe Garcea,André Z. De Pieri
Biotemas , 2012,
Abstract: Italy is one of the main apple producers in Europe, primarily intended for fresh consumption, both in the domestic and foreign markets. Fruit yield and quality depends on the cultivar, rootstock, and management practices, such as the fertilization and irrigation adopted in the orchard. This review aims at reporting the main apple cultivars and rootstocks, the management of fertilization and irrigation, as well as their adaptation to apple tree orchards in Italy. The programs for genetic improvement carried out in this country involved the selection of apple tree cultivars and rootstocks which enable a high fruit yield and quality, in order to meet the requirements from the consumer market. In the fertilization and irrigation management, nutrients and water are supplied in amounts next to the actual need of the plants, providing an adequate nutrition, a satisfactory yield, and high quality fruits, besides preventing, whenever possible, nutrients and water losses in the environment.

Abstract: The agronomic techniques adopted for stone fruit trees cultivation should be ecologically and economically sustainable. This implies that production processes, apart from improving fruit yield and quality, mantain or increase the value of natural resources, guaranteeng satisfactory incomes to growers. The paper discusses fertilization and soil management aspects for peach, species largely investigated, and other stone fruit species, with emphasis on the Italian fruit industry. As técnicas adotadas no cultivo das frutas de caro o ou drupáceas devem ser definidas com uma vis o de sustentabilidade ecológica e econ mica. Tal vis o sugere que os aspectos produtivos, voltados ao aumento da qualidade, sejam compatíveis com o ambiente, mantendo e, se possível, aumentando a qualidade dos recursos ambientais e garantindo, ao mesmo tempo, um adequado retorno econ mico aos fruticultores. No presente trabalho s o discutidos aspectos da fertiliza o e manejo do solo das drupáceas, assumindo como modelo o pessegueiro, espécie mais estudada, sendo evidenciados alguns resultados obtidos recentemente em outras espécies do grupo, com ênfase na Itália, mas que podem ser aplicados, na maioria dos casos, em qualquer situa o.

Abstract: Objetivo: Exponer y compartir nuestra experiencia en resonancia magnética de cuerpo entero (RMCE). Material y métodos: Se realizó estudio prospectivo entre octubre de 2005 y mayo de 2007 sobre 165 RMCE. Edad de los pacientes: 21 y 85 a os, media de 51,64. Se utilizó equipo de 1,5 Tesla de campo magnético y tabla deslizable. El protocolo de estudio estuvo integrado por cortes coronales multicontraste (T1, T2 y STIR), axiales y sagitales en T2. Resultados: Se obtuvieron 140 (84,84 %) estudios con hallazgos relevantes y 25 (15,15 %) sin alteraciones. Se halló predominancia de enfermedades degenerativas articulares del esqueleto axial en 94 pacientes (56,96%) sin diferencias significativas entre sexos. Trece pacientes realizaron controles oncológicos demostrándose diseminación a distancia en 6 estudios. En 1 examen se registró la distribución de polimiositis. Conclusiones: La RMCE no representa solamente una innovadora herramienta diagnóstica, sino también ostenta el potencial de competir con metodologías preexistentes en aplicaciones oncológicas y no oncológicas. La sensibilidad y especificidad del método están probadas, pero su aplicación se encuentra limitada por el alto costo y la falta de inclusión en protocolos diagnósticos de estadificación tumoral.

Northern Exposure: The New Danish Model of Citizenship Test
Silvia Adamo
International Journal of Multicultural Societies , 2008,
Abstract: The paper begins with a discussion of the general context ofnaturalisation in Denmark from a politico-legal angle, and sets theframe for the current debate on the introduction of the citizenship test. The second section analyses the content of the citizenship test and the arguments that have accompanied its adoption. The third section offers a more theoretical approach to the use of citizenship tests,evaluating the arguments in favour and against this practice incitizenship regulation. In this analysis, comparisons are drawn withthe Canadian citizenship test and policy, and reference made to thetheoretical model of multiculturalism developed by Will Kymlicka.The conclusion is provisional and takes into consideration the factthat the citizenship test is a relatively new introduction in Denmark,which makes its impact difficult to measure in empirical terms. There is, however, some evidence to suggest that the test was introduced in Denmark as another rung on the ladder to achieving citizenship, adding to the other rather onerous requirements already in place (long residence, advanced language skills and renunciation of former citizenship). For many applicants it thus may play a gatekeeping role.
Norepinephrine and octopamine: linking stress and immune function across phyla
SA Adamo
Invertebrate Survival Journal , 2008,
Abstract: In species from three widely divergent phyla (Arthropoda, Mollusca and Chordata) tyrosine derivatives (norepinephrine or octopamine) mediate a response to acute stress. Part of this response is a change in immune function that results in a decrease in resistance to pathogens. This decrease in disease resistance appears maladaptive. However, if the connections between norepinephrine/octopamine and immune function were maladaptive, they should have been selected against. None of the four commonly proposed adaptive explanations for acute stress-induced changes in immune function fit the available data for species from all three phyla. However, this result is probably due to the lack of information about acute stress-induced immunosuppression in invertebrates and a lack of ecologically valid studies in vertebrates. Understanding why immune function and disease resistance changes during acute stress will require greater comparative study.
The Imprints Of Galactic Environment On Cluster Formation and Evolution
Angela Adamo
Physics , 2015,
Abstract: Young star clusters (YSCs) appear to be a ubiquitous product of star formation in local galaxies, thus, they can be used to study the star formation process at work in their host galaxies. Moreover, YSCs are intrinsically brighter that single stars, potentially becoming the most important tracers of the recent star formation history in galaxies in the local Universe. In local galaxies, we also witness the presence of a large population of evolved star clusters, commonly called globular clusters (GCs). GCs peak formation history is very close to the redshift (z~2) when the cosmic star formation history reached the maximum. Therefore, GCs are usually associated to extreme star formation episodes in high-redshift galaxies. It is yet not clear whether YSCs and GCs share a similar formation process (same physics under different interstellar medium conditions) and evolution process, and whether the former can be used as progenitor analogs of the latter. In this invited contribution, I review general properties of YSC populations in local galaxies. I will summarise some of the current open questions in the field, with particular emphasis to whether or not galactic environments, where YSCs form, leave imprints on the nested populations. The importance of this rapidly developing field can be crucial in understanding GC formation and possibly the galactic environment condition where this ancient population formed.
Twistor actions for gauge theory and gravity
Tim Adamo
Physics , 2013,
Abstract: This is a review of recent developments in the study of perturbative gauge theory and gravity using action functionals on twistor space. It is intended to provide a user-friendly introduction to twistor actions, geared towards researchers or graduate students interested in learning something about the utility, prospects, and shortcomings of this approach. For those already familiar with the twistor approach, it should provide a condensed overview of the literature as well as several novel results of potential interest. This work is based primarily upon the author's D.Phil. thesis. We first consider four-dimensional, maximally supersymmetric Yang-Mills theory as a gauge theory in twistor space. We focus on the perturbation theory associated to this action, which in an axial gauge leads to the MHV formalism. This allows us to efficiently compute scattering amplitudes at tree-level (and beyond) in twistor space. Other gauge theory observables such as local operators and null polygonal Wilson loops can also be formulated twistorially, leading to proofs for several correspondences between correlation functions and Wilson loops, as well as a recursive formula for computing mixed Wilson loop / local operator correlators. We then apply the twistor action approach to general relativity, using the on-shell equivalence between conformal and Einstein gravity. This can be extended to N=4 supersymmetry. The perturbation theory of the twistor action leads to formulae for the MHV amplitude with and without cosmological constant, yields a candidate for the Einstein twistor action, and induces a MHV formalism on twistor space. Appendices include discussion of super-connections and Coulomb branch regularization on twistor space.
