Mediterranean fluvial environments have responded sensitively to past changes in climate, physiographic conditions and human activity. Chronosequences of river terraces and alluvial deposits were established using morphologic, sedimentological and pedologic criteria, Cand Pb-dating techniques, historical data and pottery fragments. The objective of this study addresses the fluvial dynamic of se...

In multiple myeloma the typical bone lesions are usually purely osteolytic and the presence of any osteosclerosis suggests that the diagnosis should be reconsidered. There have now been reports of forty-nine patients with myeloma with osteosclerotic deposits in whom radiotherapy could not be implicated as a cause (Kr , Wiedermann, Vykydal and Soyka 1967; Evison and Evans 1967; Osuntokun, Akinku...

In Latin America, metallic ores are abundant and diverse. However, few metal-tolerant and metal hyperaccumulator plants have been reported in the region in comparison with other areas of the world. This may be largely explained by the scarcity of scientific studies of the native vegetation growing on natural mineralized or metal-contaminated areas and the unfrequent use of biogeochemical prospe...

Aeolian (wind) processes can transport particles over large distances on Mars, leading to the modification or removal of surface features, formation of new landforms, and mantling or burial of surfaces. Erosion of mantling deposits by wind deflation can exhume older surfaces. These processes and their effects on the surface must be taken into account in using impact crater statistics to derive ...

Buried hydrocarbon deposits, such as liquid petroleum, represent an abundant source of reduced carbon for microbes. It is not surprising therefore that many organisms have adapted to an oily, anaerobic life deep underground, often at high temperatures and pressures, and that those organisms have had, and in some cases continue to have, an effect on the quality and recovery of the earth’s dimini...

In this paper an experimental investigation on the thermal storage capacity for a typical composite mixture of paraffinGraphiteCu PCM composite has been studied. Paraffin wax was used as the base phase change material (PCM) and the paraffin has been mixed with Cu turnings in different ratios 10, 50, 70 and 90 weight percentages and considered as a composite. The thermal charge and discharge cap...

Anatomical analysis of the plant tissues is an important technique used in research for studying process growth, development, adaptation to environmental stress as well characterizing gene localization. In Vietnam, most anatomical material was manually conducted which time-consuming and labor-intensive. this report, we present innovative method that can deliver high-quality rice root sectioning...

The spatial distribution of mineralization is the foremost concern in regional exploration and it could be considered as a very important tool in the investigation of mineral deposits. There are several data manipulation methods by which the data can be evaluated. Fry analysis is a good method to determine the direction(s) of maximum continuity of the deposits and could be used in different typ...
