Planation surface is the consequence of the denudation and planation processes under a tectonic stable condition. The quantitative expression of the characteristics of planation surface plays a key role in reconstructing and describing the evolutionary process of landforms. In this study, Landform Planation Index(LPI), a new terrain derivative, was proposed to quantify the characteristics of planation surface. The LPIs were calculated based on the summit surfaces formed according to the clustering results of peaks. Ten typical areas in the Ordos Platform located in the central part of the Loess Plateau of China are chosen as the test areas for investigating their planation characteristics with the LPI. The experimental results indicate that the LPI can be effectively used to quantify the characteristics of planation surfaces. In addition, the LPI can be further used to depict the patterns of spatial differentiation in the Ordos Platform. Although the present Ordos Platform area is full of the high-density gullies, its planation characteristics is found to be well preserved. Furthermore, the characteristics of the planation surfaces can also reflect the original morphology of the Ordos Platform before the loess dusts deposition process evolved in this area. The statistical results of the LPI show that there is a gradually increasing tendency along with the increasing of slope gradient of summit surface. It indicates that the characteristics of planation surfaces vary among test areas with different landforms. These findings help to deepen the understanding of planation characteristics of the loess landform and its underlying paleotopography. Results of this study can be also served as an important theoretical reference value for revealing the evolutionary process of loess landform.展开更多

The objective of the study was to evaluate in-field spatial variability of soil pH, and compare the efficiency of managing soil pH through site-specific method vs. uniform lime application. The study was conducted on three sites with study sites I and II (23°50' S; 29°40' E), and study sites IIl (23°59' S; 28°52' E) adjacent to each other in the semi-arid regions of the Limpopo Province, South Africa. Soil samples were taken in four replicates from geo-referenced locations on a regular grid of 30 m. Soils were analyzed for pH, and SMP buffer pH. Soil maps were produced with Geographic Information System (GIS) software, and soil pH datasets were interpolated using a geostatistical tool of inverse distance weighing (IDW). Soil pH in the fields varied from 3.93 to 7.00. An excess amount of lime as high as 30 t/ha under uniform lime application were recorded. These recommendations were in excess on field areas that needed little or no lime applications. Again, there was an under applications of lime as much as 35 t/ha for uniform liming applications. This under- and over-recommendations of lime based on average soil pH values suggests that uniform soil acidity correction and soil pH management strategy is not an appropriate strategy to be adopted in these fields with spatially variable soils. The field can be divided into lime application zones of (1) high rates of lime, (2) low rates of lime and (3) areas that requires no lime at all so that lime rates are applied per zone. A key to site-specific soil acidity correction with lime is to reach ideal soil pH for the crop in all parts of the field.展开更多

In this study, a loess-palaeosol sequence from the Chumbur- Kosa (CK) site in the Sea of Azov region was investigated to reconstruct climatic variability during the Marine Isotope Stage (MIS)11- MIS 1, using proxies of grain size (GS), magnetic susceptibility (xlf and Xfd(%)), carbonate content (CaCO3%) and soil color The results enabled formulation of a detailed description of the climatic characteristics related to each individual layer. The sequence indicates that the paleoclimate shifted progressively towards increasingly cooler, somewhat drier conditions. The CK section may thus be ideal for reconstructing climatie eondifions during the Middle and Late Pleistocene in the Sea of Azov region. However, the )Of value of paleosol $2 in the CK profile indicates different characteristics from the other paleosol layers, dilution of carbonate resulting from carbonate leaching in L2 may be the main reason for the decrease in magnetic susceptibility. Furthermore, through simple analysis part of the environmental evolution process in the Sea of Azov region and Serbia during Middle and Late Pleistocene cycles. The climate cycle expressed by Xfd(%) and Xlf variations show similar patterns, with rapidly alternating cold and warm intervals. Nevertheless, although the two areas had different climatic regimes, geographical settings, and loess source areas, both exhibited similar climate change trends since the MIS 11.展开更多

In Spain, these systems are relatively new because, until recently, ownership of patients' medical records belonged to the health institution. The proposed system gives patients all the information about their medical records, online. The difference from other initiatives is that the hospital provides patients with information and the latter are responsible for its future use. Importantly, this application allows physicians to carry out a personalized and individualized monitoring and treatment of each patient. The tests were conducted with real patients, all with a chronic disease (to show each patient the personalized data). They all expressed their appreciation of this application's usefulness, and obtained satisfaction level was very high. Thanks to having medical information stored on the proposed system, it can be provided to other specialists to improve the knowledgement about the patient.展开更多

Enhancement of business agility is not possible unless greater flexibility is built into IT infrastructure. More often than not, MIS's today are not flexible enough in this sense to agilely accommodate demands for system change incessantly confronting them. We have been focusing our research on MIS flexibility, its evaluation and the development of methodology for its enhancement. This paper aims to present a comparative evaluation via future oriented POC (penalty of change) analysis of system alternatives involving a case of new technology implementation. To start with, we will define the concept of MIS flexibility. We will then describe an actual case of technology implementation and define the problem it involved and go on to illustrate the evaluation procedure of MIS flexibility via future oriented POC analysis.展开更多
