Logical and Theoretical Foundations of African Environmental Ethics

[English] The paper observed that the various ethics that constitute the system of African environmental ethics are not based on or linked to any known African ontology and formal logic. It argued that the contextualisation of African environmental ethics on African ontology and African logic is essential since Western ontology and logic do not serve to adequately explain and provide proper meanings to the various concepts and propositions employed in the African environmental ethics. Therefore, the paper aimed to, and indeed, link and establishes African environmental ethics on a definite and sound African ontology and formal logic based on Ibuanyidanda complementary ontology and Ezumezu integrativist logic.

The Space of Experience in the Architecture of Richard Hamilton

Richard Hamilton realiza tres exposiciones en el Institute of Contemporary Arts (ICA) en el Londres de los años 50, participando del ambiente interdisciplinar del Independent Group. Estos montajes exploran la transformación de la sala a través de la construcción de estructuras que incentivan la participación activa del espectador. A partir del estudio realizado, para el que se reconstruyen estas propuestas siguiendo su lenguaje técnico original, se analiza cómo los montajes de Hamilton siguen un proceso evolutivo, en el que parte de la exploración de la forma a partir de patrones de crecimiento natural, continúa elevando la técnica a herramienta creativa y concluye con la formulación del espacio de interacción con el espectador. Este último montaje, an Exhibit, sintetiza los hallazgos de los anteriores, dando lugar a una propuesta arquitectónica a modo de tablero de juego que es protagonizada por la experiencia vivida de sus visitantes. Esta arquitectura es una estructura soporte que se genera a partir de un crecimiento orgánico ilimitado de un módulo estandarizado, de combinaciones variables y cambiante a cada momento por sus ocupantes. Los espacios expositivos de Hamilton recogen influencias de las vanguardias y tienden puentes hacia propuestas arquitectónicas contemporáneas entendidas como soporte para la incentivación de la experiencia de sus habitantes.Richard Hamilton held three exhibitions at the Institute of Contemporary Arts (ICA) in London in the 1950s, participating in the interdisciplinary environment of the Independent Group. These exhibitions explored the transformation of the room through the construction of structures that encouraged the active engagement of the viewer. Based on the study carried out, for which these proposals are reconstructed following their original technical language, an analysis is made of how Hamilton’s montages follow an evolutionary process, in which the exploration of form based on patterns of natural growth continues to elevate the technique to a creative tool and concludes with the formulation of the space of interaction with the spectator. This last montage, an Exhibit, summarised the findings of the previous ones, giving rise to an architectural proposal in the form of a game board whose focal element is the experience of its visitors. This architecture acts as a supporting structure that is generated from an unlimited organic development of a standardised module, with varying combinations, and which constantly changes for its occupants. Hamilton’s exhibition spaces draw on influences from the avant–garde and build bridges towards contemporary architectural proposals understood as a support for incentivising the experience of its inhabitants

Landscape Urban Structure Design - S. Romão Sportive Park, Leiria Polis, Portugal

It is due to the modern movement the loss of both landscape and open spaces multifunctionality. Consequently, it merges the term of “green spaces” amorphous and residual, often void and without any appropriation, so characteristic of the contemporary city. This study is a reflexion about and a practice result of the return to these spaces multifunctionality through a landscape structure on the urban space. We want this structure to be continuous, structuring and assuring biologic processes and fluxes that occur in the landscape systems. We present the casestudy of S. Romão Sportive Park included in Polis Program of Leiria City, in Portugal. It is a system of open spaces that constitutes itself as a landscape structure, continuous and multifunctional

Sustainable Irrigation Management of Ornamental Cordyline Fruticosa “Red Edge” Plants with Saline Water

The aim of this work was to analyze the influence of the salinity of the nutrient solution on the transpiration and growth of Cordyline fruticosa var. “Red Edge” plants. A specific irrigation management model was calibrated with the experimental data. An experiment was performed with four treatments. These treatments consisted of the application of four nutrient solutions with different electrical conductivity (ECw) levels ranging from 1.5 dS m−1 (control treatment) to 4.5 dS m−1. The results showed that day-time transpiration decreases when salt concentration in the nutrient solution increases. The transpiration of the plant in the control treatment was modelled by applying a combination method while the effect of the salinity of the nutrient solution was modelled by deriving a saline stress coefficient from the experimental data. The results showed that significant reductions in plant transpiration were observed for increasing values of ECw. The crop development and yield were also affected by the increasing salinity of the nutrient solution. A relationship between the ECw and the relative crop yield was derived

Swimming performance of Bradyrhizobium diazoefficiens is an emergent property of its two flagellar systems

Many bacterial species use flagella for self-propulsion in aqueous media. In the soil, which is a complex and structured environment, water is found in microscopic channels where viscosity and water potential depend on the composition of the soil solution and the degree of soil water saturation. Therefore, the motility of soil bacteria might have special requirements. An important soil bacterial genus is Bradyrhizobium, with species that possess one flagellar system and others with two different flagellar systems. Among the latter is B. diazoefficiens, which may express its subpolar and lateral flagella simultaneously in liquid medium, although its swimming behaviour was not described yet. These two flagellar systems were observed here as functionally integrated in a swimming performance that emerged as an epistatic interaction between those appendages. In addition, each flagellum seemed engaged in a particular task that might be required for swimming oriented toward chemoattractants near the soil inner surfaces at viscosities that may occur after the loss of soil gravitational water. Because the possession of two flagellar systems is not general in Bradyrhizobium or in related genera that coexist in the same environment, there may be an adaptive tradeoff between energetic costs and ecological benefits among these different species.Fil: Quelas, Juan Ignacio.
