background: cardiac rehabilitation has been recognized as one of the most effective strategies for managing cardiovascular indices as well as controlling the cardiovascular risk profile, in particular after coronary artery bypass graft surgery (cabg). however, the effect of this program on right ventricular function following cabg is unclear. the aim of this study was to evaluate the impact of ...
Himalaya is a vast and diverse mountain system. Agro forestry land use covering (20%) of geographical area of Indian Himalayas is distributed as patches in the matrix of forest covering (52%) area. Forest based treecrop livestock integrated farming is the predominant traditional land use in central Himalayas.1 Hill agriculture appears to be key threat to soil biodiversity and ecosystem service ...
because soil moisture condition affects vegetation changes hence, monitoring of drought and vegetation changes are among valuable management tools in these ecosystems. nowadays, satellite images are used as a low-cost and fast method for vegetation study in different scales. vegetation change is assessed using vegetation spectral characteristics. this study aimed to analyze and monitor the vege...
Detailed modeling of floodplain flows and associated processes requires data on mixed, heterogeneous vegetation at river reach scale, though the collection of vegetation data is typically limited in resolution or lack spatial information. This study investigates physically-based characterization of mixed floodplain vegetation by means of terrestrial laser scanning (TLS). The work aimed at devel...
Railway construction is one of the important activities in the development of any country and in developing countries, the need for roads is one of the main axes of development. Railway construction operations can effect on desert rangelands around railway. This study investigates the effects of Yazd-Eghlid railway construction on vegetation diversity and richness in the rangelands of Kalmand-...
In this paper we propose a model to analyze community dynamics. Recently, several methods and tools have been proposed to extract communities from static graphs. However, since communities are not static, but change over time, it is necessary to provide methods to determine and observe the community transitions and to extract the factors that cause the development. We regard a community as an o...
Figure 1: Rare Event Detection includes both Rare Mutation Detection (RMD) and Rare Species Detection (RSD). RMD and RSD can be classified according to their assay components. An RMD assay is comprised of a single primer set plus two competitive probes. RSD utilizes either a single assay to detect a rare species per unit volume (Case 1) or two independent, noncompetitive assays to detect a rare...
Hominid-bearing sites of the north western part of the Woranso-Mille research area, dated to between 3.7 and 3.8 Ma., yield 10 species of Bovidae. The evolutionary stages of the most common species fit quite well this radiometric age. The most abundant bovid is a new species of Aepyceros, of large size, with upright, lyrated horn-cores; it is clearly distinct from the impalas of younger sites i...
ation of spores the means by which the microbe of this disease, when outside the animal body, protected itself against the external world. Shortly after this it has been found that the spores not only preserve the life but also all specific properties of the microbe, and that it is owing to this circamstance that the bacillus of anthrax is one of the most constant species of schizomycetes known...
doi: 10.1111/j.1399-3054.2006.00699.x Through identifying and understanding ecologically important dimensions of plant trait variation we gain insight into why particular trait combinations are favoured and into the implications of trait differences among species. Here, we describe relationships among several poorly understood leaf and stem traits across species from several Australian vegetati...
