Geographic conditions

There are five processes employed for the manufacture of oxaUc acid as shown ia Table 3 (58). Processes are selected depending on geographical conditions. 

This water cycle—the process of moving water from oceans to streams and hack again— is essential to the generation of hydroclcctricity. Moving water can be used to perform work and, in particular, hydroelectric power plants employ water to produce electricity. The comhination of abundant rainfall and the right geographical conditions is essential for hydroelectric generation. 

Variable geographical conditions and distribution of emission source causes highly uneven distribution of ecosystem-specific deposition patterns across Europe. From the viewpoint of the adverse effects it appears that the most interesting ecosystems are forests, arable lands, grasslands, and freshwaters. In Figure 19 depositions of cadmium to forests and to arable lands are exemplified. As seen, in areas where there are both forests and arable lands, deposition fluxes to forests are substantially higher than to arable lands. 

Hydropower is the mechanical conversion of the potential and kinetic energy of water into electricity in hydroelectric plants. The geographical conditions of the regions, as well as detailed information on water conditions, such as available head... 

Plant cells can be cultivated where they are needed regardless of weather and geographical conditions. As a result, there is no need to ship or store bulky raw materials. 

Other uses of tires are sometimes feasible for specialized geographic conditions. Cape May County, New Jersey uses 100,000 tires per year, which is 100 percent of its scrap tires, for artificial reefs. The State of Minnesota has used about a million of its tires since 1986 for roads in swampy areas.

From these data on pesticide usage, the environmental effects associated with adoption of GM crops will be assessed both qualitatively and quantitatively. Qualitatively, the impact will be predicted based on, for example, properties of pesticides, quantities of applied pesticides, times of application, pest characteristics, and geographic conditions. Subsequently, the quantitative assessment will employ methods such as environmental indicators that allow for a comparison of the environmental impacts of different pesticide regimes. The enviroiunental impact may also cover other important parameters associated with altered agronomic practices under GM crop cultivation, such as tillage practices and farmland biodiversity. 

In calculating emission standards, we must consider not only the effects close to the source but also those at far greater distances caused by pollutants gradually filling the basin. This becomes especially important when meteorological and geographical conditions limit the dispersing of the pollutants and the capacity of an area to accommodate... 

Although less prone to geographical determinism than the letter from Engels on which Marx s article was based, (he argument is ambiguous. To explain the difference between East and West Marx invokes both the difference in the level of productive forces ("civilization" ) and different geographical conditions. To understand the relative importance of these two explanatory factors, we must go to an important text from Capital / ...

Physical-geographical conditions combination of steppe and forest-steppe. The climate is temperate continental in winter the mean monthly air temperature is about 10 degrees below zero, in summer it is about 20 degrees above zero. Snow cover is extensive and reaches 30 -50 cm. The relief is partially plane, partially covered with hills. The highest points are about 800 - 900 m above the sea level. The average duration of positive temperature period comprises 200 - 250 days a year. 

For further analysis of the long-distance transport of aerosol pollution to the Tien-Shan territory, the backtrajectories (BT) of air transfer were developed at a level of the leading current 500 gPa, taking into account the regional physico-geographical conditions. 

To produce secondary metabolic products from plants, exogenous plant tissue instead of a whole plant may be cultivated as a suspension culture in an aseptic condition. Such cultivation provides several advantages (1) Plant cells can be cultivated where they are needed regardless of weather and geographical conditions. (2) The product quality and yields can be well controlled by eliminating problems encountered in the processing of botanicals. (3) Some metabolic products can be produced from suspension cultures in higher quantities than those observed in whole plants.
