Nitrogen (N) is an element with a high influence in seedling growth in the nursery. Nevertheless, absolute levels of nutrient concentration are irrelevant if the relationship among the major elements is not examined. In this work we studied the incidence of several N concentrations in two proportional relationships with potassium (K), keeping the relationship with phosphate (P) constant (i.e. 3:2:1 and 3:2:3 for N:P:K), during the rapid growing phase in the fertigation production of Austrocedrus chilensis seedlings. Seedling height, stem diameter at the collar level, total biomass, aboveground/underground biomass ratio (PSA/PSR), nutritional status and root growth potential (RGP) were measured at the end of the growing season. The two treatments combining lower concentration of N with a relationship 3:2:3 produced the highest effect on all morphological parameters assessed. The PSA/PSR was more equilibrated in the treatments with the relationship 3:2:3. The N concentration in the leaves was proportional to its concentration in the nutrient solution. The P content did not show differences among treatments, whereas the K level was higher for the treatment of lower N concentration with relationship 3:2:1. The RGP was low in all treatments. Our observations showed that the 3:2:3 relationship produced larger seedlings with a better balance of biomass partition, evidencing that the management of K in the nutrient solution has higher influence in the seedlings growth of Austrocedrus chilensis.

In Argentina, as in many other countries of the region, even today deaf people finish school as functional illiterates, with no knowledge of the pragmatic and sociocultural values of the written language. However, deaf young people are nowadays learning to read and write through Internet, e-mail, chat and SMS. This article gives evidence of their appropriation of a complex object as written language and from a non scholastic discursive practice as writing through emails. From a theoretical framework of textual grammar, the authors analyze and describe the text functions in a specific communicative situation. Their analysis includes not only the syntactic but also the discursive activity (the attitudes of the textual producer and consumer). The results show how the deaf are mastering the symbolic values of written language although they are still unaware of the pragmatic adequateness of gender and register. [ABSTRACT FROM AUTHOR]

This article describes and analyzes two approaches to the aquifers' contamination management process analysis: from an environmental impact concept and from natural risks management stages. Similarities and differences are analyzed and emphasis is given to applicability of each of them and to their characteristics. An emphasis is made on risk approach, which is less disclosed and ruled than the environmental one. Natural risks management process is described, including stages before, during, and after the event, stages widely known and taken as a guide during the management process. Such stages are the following: evaluation, prediction, prevention, alarm, and rehabilitation. In relation to underground water contamination, analysis and execution of such management stages have special characteristics, among which we can highlight two: the fact that contaminating events are not subject to a cyclical process which allows operating statistical techniques for obtaining return times and occurrence probabilities and that, in general, are processes pout off on time and which effects do not result most of the time in acute symptoms; besides, the article discusses the way how aspects related to communication and perception become relevant during prevention and alert stages.

The aim of this paper is to set a profile of the psychology school applicants by taking into account their use of cognitive learning strategies. The A.C.R.A. (Sánchez y Gallego, 1984) set of learning strategies was applied on a sample of 125 Polimodal (Secondary School) graduates. The results show that the individuals studied do not reflect on their own learning and do not frequently use strategies that would optimize their learning process. The impact of this research is oriented towards the diagnosis of the university applicants profile, to decide upon institutional devices that stimulate the use of productive strategies. These would enhance the academic development of the future university students. [ABSTRACT FROM AUTHOR]

The authors analyze a written text produced by a psychotic patient from the perspective of the theory of enunciation and of discourse analysis. The patient was diagnosed through psychoanalysis and through this theory we try to address the subject of the enunciation, in the belief that, if the subconscious is linguistically structured, the notion of such structure can lead us to ascertain the nature of that subject. We have analyzed such image in relation to its object, the macro speech acts he uses and the formal aspects of the text. Preliminary results showed that linguistics and psychoanalysis are valuable tools to interpret discourse. [ABSTRACT FROM AUTHOR]

The fire record in southernmost South America has been analyzed in palaeoenvironmental studies without incorporating a deep understanding of the subsistence patterns developped by human groups and their different environments in the past. This paper proposes to bring relevant cultural information to the discussion and also intends linking diverse cultural and environmental information relating to the subject. [ABSTRACT FROM AUTHOR]

The Quequén Grande river basin is representative of the farming systems from the Pampas region. The aquifer is the main source of water supply for all uses, which highlights the importance to study the mobility of contaminants through the soil to the saturated zone. The aim of this study was to obtain hydraulic parameters of different soil types in the region according to land use (agricultural and natural) under saturated conditions. Two study areas were selected close to the cities La Dulce (Azul Series Soil) and Lobería (Semillero Buck Series Soil), as representatives of the dominant soil types in this area. The columns were eluted with an aqueous solution containing chloride ions and the progressive increase was measured at the end of the column. From the experimental data the breakthrough curve was adjusted using MATLAB software while dispersivity and porosity values were determined from modeled data. These parameters did not differ significantly in Lobería, so it is assumed that tillage does not produce significant changes in the soil profile. Conversely, in La Dulce land use affects the hydraulic properties of the soil leading to lower porosity and higher dispersivity values in soils under tillage use. [ABSTRACT FROM AUTHOR]

In underground water studies, a big amount of data is generated and compiled: these data should be jointly processed, correlated, and analyzed in order to look for relations and/or patterns through which appropriate conceptual and numerical models are defined for explaining, in a coherent way, hydro-geological functioning in a specific zone. Geographic Information Systems (GIS) must be considered as one of the basic tools of hydro-geologists, because they allow storing, analyzing, and visualizing data and information in an easy and dynamic way, as well as the analysis of their behavior in both spatial and temporal dimensions. However, in many cases, the use of GIS in hydro-geological projects has been limited to both the elaboration of cartography of different hydro-geological units included in the study area and to the location of different measurements and parameters related to underground water resources, without taking advantage of their capabilities for the analysis of complex multivariate spatial phenomena. The present research presents two GIS application examples in Latin America which have helped in the modeling and pre-processing of the phenomena and the involved variables, in addition to the traditional identification of different essential characteristics of aquifers.
