Very low air quality in the Warsaw conurbation, Poland, similarly to case many large European cities, poses a serious threat residents’ health, being significant source of premature mortality. Many results presented earlier publications indicated local heating installations and car traffic as main emission categories responsible for this adverse population exposure, where dominant polluting com...
We analyze a repeated game in which countries are polluting and investing in technologies. While folk theorems point out that the first best can be sustained as a subgame-perfect equilibrium when the players are sufficiently patient, we derive the second-best equilibrium when they are not. This equilibrium is distorted in that countries over-invest in technologies that are “green” (i.e., strate...
For the past few decades, there has been a considerable in research interest in the area of natural product delivery using particulate for controlling plant pathology. The secondary metabolites in plants have been used in the formulation of nanoparticles through increase the effectiveness of therapeutic compounds used to reduce the spread of plant diseases, while minimizing side effects for bei...
ii abstract the legend of human being’s refulgence was distorted completely in the age of modernity. this new age, had some drastic negative effects, besides its positive qualities. one significant negative effect of it was the emergence of neurosis in human beings. aldous huxley’s brave new world was one of the novels of the 02 th century that contained the prophecy of criticizing ...
today, the route for economic development in most countries is the same as international open competitive economy. economic institutes well known that supportive public economy belonged on the past and they may compete in the global economy. it is obvious that if they have no competitive potency or not familiar with competition technique, they may be devastated. banking system aims to collect t...
The need for mankind to make the transition from a global civilisation powered by fossil fuels, to one powered by non-polluting sources of energy, is at last beginning to impinge on public awareness, now that the science of climate change is becoming established. Unfortunately, obfuscation and procrastination still exists, impeding progress to sustainability as vested interests are increasingly...
Urban highways, as one of the most important sectors of transportation, have always been one of the most challenging, both in terms of budget consumption and its spatial, social, economic and environmental impacts on the city. It has been urban elements. To this end, this study analyzes the impacts of inter-city highways, examines the theories of how to deal with this spatial element, as well a...
In this paper we consider a dynamic nonzero-sum game between the polluting firms and the authorities. Although the proposed game is not easily solvable for the feedback case, i.e., it is not the linear quadratic case of game and not a degenerated case, we calculate explicitly a stationary feedback equilibrium. In the proposed game the regulator has the ability to turn the optimal allocation of ...
the community dynamics of aquatic coleoptera(insecta)in one of the spring-stream habitats of bammo national park in fars province called cheshmeh-ye-ghanbari is studied as a pilot project and model for acquaintance with and furthering the biodiversity studies on fauna of iran. sixteen species-populations out of nineteen of this community were already identified for their taxonomy and for thei...
