Propozycja regionalizacji fizycznogeograficznej Sudetów Wschodnich

2018

Artykuł przedstawia propozycję wyznaczenia granic Sudetów Wschodnich oraz podziału fizycznogeograficznego makroregionu na mezoregiony. Przy wyznaczaniu granic uwzględniono w większym stopniu genetyczno-geologiczny podział Sudetów związany z orogenezą waryscyjską. W podziale na mezoregiony w większym stopniu uwzględniono kryteria litostratygraficzne.

An Easy Stereoselective Access to β,γ-Aziridino α-Amino Ester Derivatives via Mannich Reaction of Benzophenone Imines of Glycine Esters with N-Sulfon…

2007

Mannich-type addition of benzophenone imine glycinates across newly synthesized N-(p-toluenesulfonyl) alpha-chloroaldimines afforded gamma-chloro-alpha,beta-diamino ester derivatives with moderate diastereoselectivity as separable mixtures of anti and syn diastereomers. The gamma-chloro-alpha,beta-diamino esters were efficiently cyclized under basic conditions to the corresponding beta,gamma-aziridino alpha-amino ester derivatives, representing a new class of conformationally constrained heterocyclic alpha,beta-diamino acid derivatives. The relative configuration of the aziridines was determined via X-ray diffraction analysis. Mechanisms and intermediate transition states to explain the ste…

Stochastic model for complex surface-reaction systems with application toNH3formation

1993

A stochastic model is introduced that is appropriate to describe surface-reaction systems. These reaction systems are well suited for the description via master equations using their Markovian behavior. In this representation an infinite chain of master equations for the distribution functions of the state of the surface, of pairs of surface sites, etc., arises. This hierarchy is truncated by a superposition approximation. The resulting lattice equations are solved in a small region which contains all of the structure-sensitive aspects and can be connected to continuous functions which represent the behavior of the system for large distances from a reference point. In the present paper, we …

Reply to "comment on 'Monte Carlo simulations for a Lotka-type model with reactant surface diffusion and interactions' ".

2002

As is well known, a wide class of physical problems, including the kinetics of heterogeneous catalytic reactions, is traditionally described in terms of the master equations ~ME!. The definition of ME allows us not only to perform Monte Carlo ~MC! simulations, but also to develop at the same time appropriate analytical methods @mean field~MF!, cluster approximations, etc. #@ 1#. ME is formally defined when all possible states of a system and the transition rates between these states are specified. This is enough to define only the transition rates K(i! j ) for such elementary processes as particle adsorption, desorption, diffusion, reaction, etc., from the initial state i to the final state…

Climate change is a major challenge for sustainable development, impacting human health, wellbeing, security, and livelihoods. While the post-2015 development agenda sets out action on climate change as one of the Sustainable Development Goals, there is little provision on how this can be achieved in tandem with the desired economic progress and the required improvements in health and wellbeing. This paper examines synergies and tensions between the goals addressing climate change and economic progress. We identify reductionist approaches in economics, such as ‘externalities’, reliance on the metric of the Gross Domestic Product, positive discount rates, and short-term profit targets as som…

Integrated approach to the assessment of waste management systems within the SEA framework

2007

This paper addresses the problem of evaluating the environmental performances of Urban Waste Systems. Specifically, the paper refers to the crucial problem of environmentally analysing the Urban Waste System Management Process. The application of the Dashboard of Sustainability has been deliberately suggested. The method has been selected because of its intrinsic simplicity and because it can provide the simultaneous evaluation of indicators which refer to different fields, such as the Environment, Economics and Quality in Institutional Services. The method has been applied to the city of Palermo. The results obtained have been compared to a couple of ideal scenarios.

PPGIS applied to environmental communication and hazards for a community-based approach: a dualism in the Southern Italy "calanchi" landscape

2021

<abstract> <p>The need of protection of the territory is a priority for the society, which is an integral part of it (unfortunately, this coincidence is often forgotten): the new environmental issues require the development of innovative management strategies and of appropriate knowledge and models. The balanced use of resources, essential for the survival and well-being of society, can be optimised through the promotion of the territory. The identification and the sustainable development of local resources can only be achieved by directing development policies towards a path of integration between ecological needs, protection of the landscape and socio-economic and cultural nee…

Precaution and protection policies of urban ecosystem in the Iblea north eastern coast of Sicily

2005

According to the hypothetical urban scenarios in the future, the urban ecosystem will be the piace where the most part of people live, with a deep negative impact on the world ecosystem. So it is necessary for all the people to get better ways of life in the towns and less and less unbalanced urban space, that to say a clean, efficiency and productive place that satisfies the needs of its inhabitants. A fundamental aim to the restoration of conditions of equity in the city seems to come from the models of development of sustainable city, related to the improvement of the environment and, above all, to a plan of sustainable society. Leaving from the indications of the European urban policies…
