Management of irrigation water and nutrient demands of tomato (Lycopersicon esculentum Mill.) using urban treated wastewater from a pilot-scale horiz…
2017
The reuse of treated wastewater (TWW) in crop irrigation is an advanced and rational approach to water resource management in agriculture. Results would seem to demonstrate that it could be an extremely important tool in the reduction of freshwater (FW) consumption in agriculture, at the same time helping to increase crop yields through the transfer of nutrients required for crop growth. In arid and semi-arid areas of the Mediterranean, constructed wetlands can play a key role in the treatment and reuse of wastewater due to their multifunctional nature. The aim of this study was to manage water and nutrient requirements of tomato (Lycopersicon esculentum Mill.) using TWW from a pilot-scale …
Subduction of the Nazca Ridge and the Inca Plateau: Insights into the formation of ore deposits in Peru
2005
A large number of ore deposits that formed in the Peruvian Andes during the Miocene (15-5 Ma) are related to the subduction of the Nazea plate beneath the South American plate. Here we show that the spatial and temporal distribution of these deposits correspond with the arrival of relatively buoyant topographic anomalies, namely the Nazca Ridge in central Peru and the now-consumed Inca Plateau in northern Peru, at the subduction zone. Plate reconstruction shows a rapid metallogenic response to the arrival of the topographic anomalies at the subduction trench. This is indicated by clusters of ore deposits situated within the proximity of the laterally migrating zones of ridge subduction. It …
High-temperature metamorphism and crustal melting at ca. 3.2 Ga in the eastern Kaapvaal craton, southern Africa
2018
Abstract The question of whether high-grade metamorphism and crustal melting in the early Archaean were associated with modern-style plate tectonics is a major issue in unravelling early Earth crustal evolution, and the eastern Kaapvaal craton has featured prominently in this debate. We discuss a major ca. 3.2 Ga tectono-magmatic-metamorphic event in the Ancient Gneiss Complex (AGC) of Swaziland, a multiply deformed medium- to high-grade terrane in the eastern Kaapvaal craton consisting of 3.66–3.20 Ga granitoid gneisses and infolded greenstone remnants, metasedimentary assemblages and mafic dykes. We report on a 3.2 Ga granulite-facies assemblage in a metagabbro of the AGC of central Swazi…
Improvement of the technological process of carbonated spring water by implementing the quality and food safety management standards
2019
Bottled spring water must be health providing, clean, without microorganisms, parasites or substances. The design, manufacturing and management of processes, related to spring water bottling involves controlling the safety issues that may arise in the production processes. These aspects are not sufficient to prevent hazards and they must be related to the implementation of a quality and food safety systems. The aim of the paper is to improve the technological process of carbonated spring water in Monopolis S.A Company, by implementing the quality and food safety management standards. The methodology is based on the implementation requirements of the HACCP principles, included in ISO 22000 s…
Growth of Arundo donax L. and Cyperus alternifolius L. in a horizontal subsurface flow constructed wetland using pre-treated urban wastewater - a cas…
2013
Constructed wetland systems for wastewater treatment represent an excellent opportunity for the recovery of water resources in those areas subject to prolonged periods of water shortage. This paper presents a study of the efficiency of a pilot horizontal subsurface flow system using pre-treated urban wastewater from a small town in the West of Sicily. The pilot system had a total surface area of 100 m2 with two units. Unit A was planted with Arundo donax L. and unit B with Cyperus alternifolius L. The HLR was 10 cm d-1. The main objectives of research were to evaluate the growth and biomass yield of two macrophytes and determine the removal efficiency of physical-chemical and microbiologica…
Analysis and reconstruction in stages of the design and construction process of the old and new basilica of S. Peter in Vatican, and its surroundings
2020
Resumen 1. Objetivos El objetivo general de esta Tesis Doctoral es reconstruir el proceso de diseño y construcción de la antigua y nueva basílica de San Pedro en el Vaticano, y de su entorno cercano. De forma complementaria, se reconstruye la evolución de la trama urbana del área del Vaticano, desde su origen hasta la actualidad. La reconstrucción del proceso de diseño y construcción se realizará de forma descriptiva y, especialmente, de forma gráfica. Los planos se realizarán con gran detalle, a escala y con gran precisión, utilizando las más avanzadas herramientas de dibujo digital. La reconstrucción de las diferentes etapas del proceso de diseño y construcción de la antigua basílica se r…
Making conservation sustainable under unfavourable conditions : the case of Chimanimani National Reserve, Mozambique
2019
Based on a case study from the Chimanimani National Reserve in Mozambique, this article analyses to what extent different types of operational practices can contribute to the sustainability of protected areas in relatively unfavourable external conditions. While current conservation policies highlight community participation and market-based approaches, the same “best practices” are not equally valid under different conditions. Where unfavourable natural conditions, lack of infrastructure, difficult access and political instability limit the potential for upmarket ecotourism, actors should focus on community empowerment, diversification of livelihoods, and building joint conservation ideolo…
L'invectivité entre catégorie pragmatique et discours. Réflexions épistémologiques à partir d'un corpus de discours de haine sur Twitter
2022
[Contexte] Cette proposition s’inscrit, dans la recherche de tradition allemande, à l’intersection entre les travaux en linguistique de discours (au sens donc de Diskurslinguistik, Spitzmüller/Warnke, 2011 ; Felder/Gardt 2015), en pragmatique (des nouveaux médias, Herring / Stein / Virtanen 2013 ; Gautier / Michel sous presse) et de la linguistique juridique (au sens de Rechtslinguistik, Felder / Vögel 2017). Plus particulièrement, elle prend pour objet les discours de haine (Hassrede, Scharloth 2017 ; Meibauer 2013) qu’elle visera à éclairer par rapport aux acquis des recherches sur l’invectivité (Invektivität) dont elle cherchera à interroger le positionnement épistémologique dans le cham…
Toward a cognitive Discourses Semantics. Theoreticals inputs and empirical corpus-based case study in German.
2021
At the intersection between usage-based construction grammar and frame semantics, a cognitive semantic analysis is to be theorized. The present work proposes to develop for this purpose the Cognitive Discourse Analysis model. Discourse is then understood following Michel Foucault as a conceptual system based on linguistic, social and epistemic knowledge. Its linguistic operationalization is achieved through the contribution of textual linguistics and corpus following Dietrich Busse. The aim of such a methodological construction is to finely examine a corpus of recurrent texts in a cognitive perspective, and thus as close as possible to the linguistic reality, and to be able represent the en…
An Empirical Investigation of Green Product Design and Development Strategies for Eco Industries Using Kano Model and Fuzzy AHP
2022
Collaboration in green product design and development is becoming more significant to ensure a brighter future for eco industries, and research into such innovation has increased in recent years. So, it has been emphasized by practitioners that green thinking should be adopted from the design stage through the development stage and into the disposal stage of a product. However, it is challenging to identify the severity of strategies that mainly hampers the growth of green product design and development (GPDD). The current research aimed to identify and rank various strategies based on their significant impact on the development of green product design. The study contains three segments: (1…
