Рассмотрены основные экономические аспекты эффективности внедрения ресурсосберегающих технологий в рекреационной сфере. Рассмотрена роль ресурсосберегающих...

This paper presents some results from a numerical model of the wind and thermal climates, and the energy budgets, of city canyons. The model is capable of simulating spatial patterns of canyon energy budget components, subsurface and air temperature, and the components of the wind, as these are...

The energy budget of a method to harvest cotton stalks developed and tested in greece is reported in the present paper. The method used conventional hay harvesting machinery. An instrumented tractor was used to measure the energy consumption during the work in the field while literature data...

Group foraging allows for individuals to exploit the food discoveries of other group members. If searching for food and searching for exploitation opportunities within a group are mutually exclusive alternatives, the decision to use one or the other is modeled as a producer-scrounger game...

Irrigated agriculture has the potential to alter regional to global climate significantly. We investigate how irrigation will affect regional climate in the future in an inland irrigation area of northern China, focusing on its effects on heat fluxes and near-surface temperature. Using the...

Cloud microphysical parameters, such as cloud droplet size (r), droplet number concentration (N<SUB align="right"><SMALL>d</SMALL></SUB>) and liquid water content (LWC), play an important role in the energy budgets of clouds, and thus the climate of the earth's atmosphere. The observations were collected during the North Atlantic...</small></sub>

The paper analyses, by applying a system of optimization models for cash flow analysis and forecasting, how effective a transfer of a part of the power generating capacities from gas to coal would be. We present a scenario analysis assuming both an increase of a gas export under a deficit of the...
