A PROPOSITO DI LIBERTÀ E COSTITUZIONE IN HEGEL DI G. DUSO

The first part of the volume addresses the issue of speculative procedure in Hegel's philos-ophy and the role played by mediation and the negative within such a process. The volume proceeds by debating the reach of the influence of Greek thought in Hegel, as well as the legacy of Jusnaturalistic modern thought. In its final part, the volume provides a reflection on the issue of social classes

From Received Pronunciation to Estuary English: a shift from diastratic variation

2010 - 2011The starting point of the present study was the idea that all the talk about Estuary English produced in the last few decades could not be ignored. The focus of the research, however, did not lie on the description of Estuary English and its ongoing development; it rather tried to concentrate on the use of this supposed middle-ground variety by speakers who, due to social factors, are generally not meant to speak it. Politicians, members of the Royal Family and BBC journalists are generally considered RP speakers; however, they sometimes shift towards less standard varieties. In this regard, questions have been asked in order to understand whether they consciously or unconsciously use Estuary English features and to investigate the place, the time and the manner for them to recur. Thus, a diaphasic perspective has been added to the prevailing diastratic relevance of the variety. The study has provided an empirical observation of the linguistic attitudes of the speakers belonging to the selected categories. Furthermore, it has verified that the Estuary English-as register-hypothesis, as proposed by Altendorf (2003), can function and represent a stylistic option for speakers who want to accommodate and converge towards wider speech communities.

Distintas fracciones de fósforo en suelos del norte de Entre Ríos

p.59-62El objetivo del presente trabajo fue evaluar y relacionar las distintas fracciones de fósforo en dos series de suelos con características vérticas. Durante las cuatro estaciones del año, se efectuaron las siguientes determinaciones analíticas: P total, P inorgánico total, P orgánico total, P-Bray 1, P-Olsen, Carbono orgánico total y pH en agua, en las series de suelos G arat (A rgiacuol vértico) y Esmeralda (Peluderte argiacuólico) bajo pastizal natura. El contenido de P total fue bajo y el porcentaje de P orgánico fue de un 63 por ciento, presentando su mayor valor durante el invierno. Esta variación estacional no fue significativa en los contenidos de P-Bray y P-Olsen. Esta homogeneidad puede estar relacionada con las características intrínsecas de los suelos vérticos, hecho que les confiere una especial capacidad buffer de fosfatos. Los niveles de P extractable fueron siempre deficientes, extrayendo Olsen un 62 por ciento del total extraído por Bra

Rupestrian Works and Artificial Cavities: Categories of Construction Techniques

Artificial cavities, i.e. man-made structures excavated within rock masses in the mountains, below the ground, or in the subsoil of urban areas, are typically distinguished based upon the epoch of realization and the function for which they were originally used. They can be ranked into the following types, in turn divided in sub-classes: hydraulic works, dwelling works, worship works, war works, mining works, transit way works and others. The above criteria are essential for establishing a general common line aimed at providing optimal elements for cataloguing and comparing subterranean features, which may favor the creation of databases functional to knowledge, protection and enhancement of the hypogean works. In addition, there is another useful aspect for studying the origin and evolution of underground structures that takes into account their implementation modalities. The National Commission on Artificial Cavities of the Italian Speleological Society has identified, according to its experience in the field and in function of the construction techniques, six general categories of underground works: cavities dug in the subsoil, cavities built in the subsoil, cavities obtained by re-cover, anomalous artificial cavities, mixed artificial cavities and natural caves modified by men (anthropized caves). In this contribution we will discuss the specific details of each category, thus extending the concept of rupestrian heritage, usually confined to temples or dwellings carved in the rock, to a culture of building in "negative" that finds larger and more diversified evidences

Characterization of some soils for high yield apple cultivation in rio negro valley

El objetivo del presente trabajo fue caracterizar la situación nutricional en suelos bajo cultivo de manzana (Malus sylvestris) en el Valle del Río Negro. Los valores de carbono aumentaron en forma significativa (P<0,05) en montes de manzano con varios años de producción. En las regiones áridas, el almacenamiento de carbono en el suelo es una ventaja de especial importancia por su influencia en las propiedades físico-químicas, que se suma a la estrategia global del secuestro de carbono atmosférico. No resultaron factores limitantes los contenidos de nitrógeno, debido a las características del sistema productivo, ni tampoco los contenidos de fósforo extractable, calcio, magnesio, pH y conductividad eléctrica, por presentar valores adecuados. Como ventaja respecto al análisis foliar que se efectúacomo rutina en la zona para el diagnóstico de fertilización, el análisis de suelos permitió detectar el aumento del contenido de carbono en los suelos bajo monte frutal. Puede resaltarse como elemento crítico en suelos al potasio, sumamente importante en la determinación de la calidad de los frutos.The objective of this work was to characterize nutritional status in soils with apple (Malus silvestrys) cultivation in Rio Negro Valley. Values of soil C significantly increased (P<0.05) in older cultivations. In arid regions, C storage in soils is a relevant advantage due to its influence in soil properties, apart of global strategy of atmosferic C sequestration. N was not a limitative factor, due to productive system characteristics, neither were P, Ca, Mg pH an EC, with adequate values. An advantage of soil analysis respecto to foliar analysis, routine technique for fertilization diagnostic, was the detection of C increase in soils of long-term apple cultivations. K was a critical element is soil, very important in furit quality determination.Fil: Giuffre, Lidia. Universidad de Buenos Aires. Facultad de Agronomía. Departamento de Recursos Naturales y Ambiente.

Argentina: Soil Organic Carbon Sequestration Potential National Map. National Report. Version 1.0. Year: 2021

Soil organic carbon (SOC) is a key factor affecting soil physical fertility, as it improves several soil properties such as infiltration, structural stability, porosity, aeration and structure. It also improves soil chemical fertility since C is part of the soil organic matter, which constitutes the main reservoir of nutrients for crops (nitrogen, sulfur, zinc, among others). SOC is positively correlated with soil microbial biomass that acts on nutrient cycling and metabolization processes of toxic molecules. The total SOC stock in topsoil (0-30cm) is about 19.7 Pg C (FAO-ITPS GSOC map, 2018). Thus, due to the size of the soil carbon pool, even small increments in the net soil C storage may represent a substantial C sink potential. Although agricultural greenhouse gas emissions (GHGs) contribute to an important share of Argentina GHG emissions (135.53 MtCO2eq, 37% of total country GHG emissions; SAyDS, 2019), increasing ASOC stocks through judicious land use and sustainable soil management (SSM) practices may represent an important strategy to reduce and mitigate GHG emissions. In Argentina, the total productive area is about 157 million hectares (INDEC, 2021). Agricultural área (croplands) is about 40 (forty) million hectares, predominantly under no tillage system (91% agricultural area; AAPRESID, 2020). Soybean is the main product (45 million tons in 17 million hectares), followed by corn (44 million tons in 6.3 million hectares), wheat (17 million tons in 6.5 million hectares), barley (4.1 million tons in 0.1 million hectares) and sunflower (2.7 million tons in 1.3 million hectares).The rest of the area (over 124 Million hectares) is occupied with grasslands and shrublands dedicated to livestock production, and other agricultural uses. In the last decade’s agricultural land increased and SOC content decayed. This process of land use change was explained by increasing soybean monoculture and displacing livestock area, reducing SOC content (Lavado & Taboada, 2009). There has been an intense expansion of agriculture at the expense of grasslands, native forests and other natural resources in semiarid, sub-humid and subtropical regions of the country (Volante et al., 2012). Currently, soils of the Chaco-Pampean region exhibit SOC levels between 40-70% of the contents of virgin soils (Alvarez & Steinbach, 2009; Sainz Rozas et al., 2011; Milesi Delaye et al., 2013). Several farming practices may be used to restore or diminish the SOC loss, reduce soil erosion, sequester atmospheric carbon dioxide (CO2 ) and improve the soil quality (Poffenbarger et al., 2020). Among these practices, the inclusion of cover crops (CC) during winter has been postulated as one of the most promising activities (Ruis & Blanco-Canqui, 2017). The inclusion of CC showed average SOC sequestration rates of 0.45 tC/ha/yr (± 0.03), in Argentina (Alvarez et al., 2017; Beltran et al., 2018; Romaniuk et al., 2018). Increasing nutrient availability, crop growth and residue returns by increasing fertilizer use showed an increment of SOC around 0.18 tC/ha/yr (± 0.03) (Duval et al., 2020; Restovich et al., 2019). The inclusion of cycles with perennial pastures in crop rotations showed average SOC sequestration rates of 0.76 tC/ha/yr (± 0.03), exhibiting the greatest potential to increase SOC stocks (Costantini et al., 2016; Gil et al., 2016). Sustainable soil management (SSM) practices (FAO, 2020) such as the above mentioned practices have demonstrated potential to increase SOC stocks in different agricultural systems in Argentina, and thus sequester atmospheric CO2 as SOC to mitigate GHG emissions. However, SOC sequestration from these practices show highly variable sequestration rates, depending on edapho-climatic conditions, land use and management, among other factors. It is therefore relevant to identify which regions, soils, climates and systems have a greater potential to increase SOC stocks, in order to establish priorities for research and implementation of private and public policies.

Guía de prospectiva para el ordenamiento territorial rural de la Argentina a nivel municipal

Esta guía ha sido elaborada para motivar y sensibilizar a los tomadores de decisiones de los municipios a incorporar la dimensión de futuro en los procesos de Ordenamiento Territorial Rural (OTR). Con tal fin, los autores presentan algunas estrategias conceptuales y metodológicas para abordar estudios de prospectiva en el marco de los procesos de OTR, tomando como base las experiencias y aprendizajes de la Provincia de Mendoza. La Guía está elaborada para ser aprovechada por un público amplio: planificadores, tomadores de decisiones, gestores del territorio y actores sociales, entre otros. Es evidente el reconocimiento que hacen sus autores acerca de la necesidad de participación de muy diversos agentes económicos, sociales y políticos en un proceso de ordenamiento territorial rural. Este es otro mérito importante, pues la Guía es cuidadosa en evitar intentar ser una especie de manual a seguir puntualmente a rajatabla, ni tampoco ser tan general como para ajustarse casi a cualquier proceso de planeación del territorio. Se ubica en un punto intermedio, a partir del cual puede ser aprovechable por los diferentes públicos.CR Mendoza-San JuanFil. Vitale Gutierrez, Javier Alejandro.

A recommender for the management of chronic pain in patients undergoing spinal cord stimulation

Spinal cord stimulation (SCS) is a therapeutic approach used for the management of chronic pain. It involves the delivery of electrical impulses to the spinal cord via an implanted device, which when given suitable stimulus parameters can mask or block pain signals. Selection of optimal stimulation parameters usually happens in the clinic under the care of a provider whereas at-home SCS optimization is managed by the patient. In this paper, we propose a recommender system for the management of pain in chronic pain patients undergoing SCS. In particular, we use a contextual multi-armed bandit (CMAB) approach to develop a system that recommends SCS settings to patients with the aim of improving their condition. These recommendations, sent directly to patients though a digital health ecosystem, combined with a patient monitoring system closes the therapeutic loop around a chronic pain patient over their entire patient journey. We evaluated the system in a cohort of SCS-implanted ENVISION study subjects (Clinicaltrials.gov ID: NCT03240588) using a combination of quality of life metrics and Patient States (PS), a novel measure of holistic outcomes. SCS recommendations provided statistically significant improvement in clinical outcomes (pain and/or QoL) in 85\% of all subjects (N=21). Among subjects in moderate PS (N=7) prior to receiving recommendations, 100\% showed statistically significant improvements and 5/7 had improved PS dwell time. This analysis suggests SCS patients may benefit from SCS recommendations, resulting in additional clinical improvement on top of benefits already received from SCS therapy
