The 3D QSAR studies using Apex 3D expert system led to the identification of the pharmacophore in terms of common biophoric sites and secondary sites for interacting with PPARγ receptors.
      
1) for R isomers with correlation coefficient r =0.9, chance= 0.05 and match= 0.47 has four biophoric sites and three secondary sites while the best model for S isomers (model no.
      
2) with correlation coefficient r =0.86, chance =0.01 and match = 0.45 has three biophoric sites and two secondary sites.
      
Biological Evaluation of a Secondary Metabolite, 9-O-methylfusarubin, from Fusarium oxysporum
      
In this paper a new mathematical model of secondary frost heave is presented.
      
From these data, it may be deduced that the administration of high concentration of 18-methyl norethindrone can displace ketoprofen from its secondary binding site.
      
By comparing ECV results with those of secondary ion mass spectroscopy (SIMS), it is found that the dopant concentration profiles in heavily-doped p+ layer as well as junction depths measured by ECV are in good agreement with those measured by SIMS.
      
fortunei plantation, and it is markedly better and shows higher accuracy than the commonly used reciprocal model of density effect and secondary-effect model.
      
These values accounted for 28.6%, 13.8%, and 61.0% of their respective counterparts in the natural secondary forests under the same site conditions in the region.
      
Although the mean total carbon density of the artificial forests in the rehabilitated lands was 281.2 t/hm2 in the experimental area, it accounted for only 41.5% of the carbon density of the natural secondary forests (677.4 t/hm2).
      
This indicates that growth and carbon storage capacity of artificial forests in the rehabilitated lands were higher than those of forests on the barren hills and the secondary forests.
      
mongolica, Pinus koraiensis and Larix gmelinii) and natural secondary forests (Fraxinus mandshurica, Quercus mongolica and Populus davidiana).
      
Results also showed that the number of species of primary concern is two; of secondary concern, nine; of the third level, 23; and of least concern, 330 species.
      
In autumn, both parameters decreased significantly due to secondary incrassation of fine root diameter or the increase of tissue density.
      
Rainfall redistribution of a virgin Pinus koraiensis forest and secondary Betula platyphylla forest in Northeast China
      
koraiensis virgin forest amounted to 98168 mm during a growing season (May to September), which was 19.6 per cent of the total rainfall and 1.3 times that of a secondary Betula platyphylla forest.
      
Compared with the secondary birch forest, the virgin pine forest had lower throughfall but higher stem-flow.
      
A linear regression equation (p >amp;lt; 0.01) was found to be a better fit for the relationship between throughfall of the secondary birch forest and rainfall outside the forest.
      
The Huanglong Mountain forest zone is one of the major natural secondary forest zones in the southern Loess Plateau in Shaanxi Province, China.
      
Twelve indices representing vegetation and soil properties in natural, secondary P.
