The discussion of carbon dioxide in its relation to biology, to the exclusion of other components of the system is a difficult, if not altogether impossible, task. We may, however, consider in a more or less general manner, certain processes in which C02 appears to be an important factor, and some of the phases of its action which have attracted particular attention. Many applications of C02 in...

In this paper, we introduce a novel graph-based method to classify the regions with similar climate in local area. We refer our proposed as graph partition based (GPBM). Our attempts overcome shortcomings of current state-of-the-art methods literature. It has no limit on number variables that can be used and also preserves nature data. To illustrate capability algorithm, benchmark its performan...

Tropospheric sulfate aerosols produced by atmospheric oxidation of S02 emitted from fossil fuel combustion scatter solar radiation and enhance the reflectivity of clouds. Both effects decrease the absorption of solar radiation by the earth-atmosphere system. This cooling influence tends to offset the warming influence resulting from increased absorption of terrestrial infrared radiation by incr...

We examined the effects of elevated C02 on growth and carbon/nutrient balance in a natural population of the deciduous temperate zone shrub Lindera benzoin. Our data concern whole plant, leaf, and stem growth for the first two seasons of a long-term field experiment in which C02 levels were manipulated in situ. In addition to growth parameters, we evaluated changes in leaf and stem chemistry, i...

abstract fars province with a share of more than 16 percent holds the highest rank in producing tomato in iran. this study aims at determining priorities for tomato processing centers in fars province’s townships. to achieve the study objective a distance minimizing pattern was used for transportation network between producing and processing centers as well as processing and consumption centers...

abstract t he return of capital is fundamental to the intertemporal allocation of resources by changing the consumption behavior and capital accumulation over time. taxation on return of capital increases the marginal product of capital, meaning that capital stock is lower than when capital is not taxed, which results decreased growth and welfare in steady state. this paper studies the impact o...
