Exogene weathering

The role of nails in human metabolism is still the unexplored field. Nowadays, on the literature sources, there is no information about elemental content of each nail of individual human. There is a little information about how the elements to get into the nail structure. Weather it is possible the exogenous elements to enter the nail or no How the elements to distribute in different nails of the same individual How the elements to distribute on the total area of nail Weather the changes in elemental composition in time take place. [Pg.430]

Study of specific regions in which iron cherts and volcanic rocks are spatially unconnected naturally led to the development of hypotheses of an exogene source of the iron, unrelated to volcanism. Thus there arose the hypothesis that the iron cherts were formed from material supplied to the sedimentary basin in the course of intensive subaerial weathering. Svital skiy (1924), Piatnitskiy (1924), Strakhov (1947), James (1954), White (1954), Belevtsev (1957) and Plaksenko (1966) shared this hypothesis. [Pg.17]

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. [Pg.1507]

It is remarkable, that only after the endogene alteration processes had finished, the rock has been exposed to the exogene processes of weathering. The change of mineral content and the increase of... [Pg.786]

The proposed model provides forecasts based only on historical sales data, which cannot reflect the effects of exogenoits factors, such as weather and economic indexes, on fashion sales. Futirre research will focus on investigating mirltivariate HI forecasting models cortsidering the effects of various exogenous changes on fashion sales. Moreover, it is also a worthwhile research direction to... [Pg.193]

Chemical equilibrium and mass transfer mechanisms (chemical reactions, diffusion, fluid flow (advection), adsorption, etc.) (Chaps. 1,2, and 3) are examined in order to illustrate the compositional variation that exists within water (ground water, hydrothermal solution, seawater) and weathered and hydrothermally altered rocks and soils. To better understand the subsystems of the earth, equilibrium and mass transfer coupling models are apphed to the seawater system, as an example of a low-temperature exogenic system, and hydrothermal systems, as an example of high-temperature endogenic systems (Chap. 4). [Pg.259]

The flow of matter from continents to oceans and to the ocean floor is obviously visible it is frequently termed exogenous or minor cycle . It describes the transfer of matter from the lithosphere to the hydrosphere and then back to the lithosphere. It is questionable whether a fragment of weathered rock, either crystalline or sedimentary in origin, moving in streams is part of the lithosphere. [Pg.18]

How is attention allocated within the maximal performance limits of each function specified in Wickens model (Figure 3-3) The answer is that it depends on a variety of things. Fortunately we are fairly flexible in our allocation, and seem to be able to change allocation of attention fairly quickly. The change is determined by multiple factors - both endogenous (such as an individual driver s experience, skills, attitudes, etc), and exogenous (such as the road, weather, and traffic conditions). An attempt to address that issue is made in a more detailed model of the demand-allocation issue, proposed by Fuller (2005), and depicted in Figure 3-10. [Pg.75]
