in this study, the role of soil properties in making difference between plant communitieswas examined. first, four plant types were identified, including pteropyrumaucheri-salsolarigida، astragalus gossypinus - acanthophyllum herateens، amygdalus scoparia – achilla millefolium and ephedra intermedia – erigon capestra, through randomized systematic sampling and field survey in representative are...

Indigenous food plants provide various social functions; they are crucial to supply diversification efforts, and improve nutrition security. Research has shown that indigenous foods’ nutritional potential advantages have yet be adequately appreciated explored. This systematic review discusses the elements contributing IF promotion, which may help increase their intake. Therefore, a literature w...

This technical note outlines an approach to the problem of synthesizing fixedstructure low-order controllers for systems whose mathematical models are unknown, but their frequency responses are available. Stability of the closed-loop system is guaranteed if the frequency response of the plant and the controller satisfy certain conditions at specific frequencies. It is shown that the relation be...

The systematic investigation on the roots of Taxus wallichiana has resulted in the isolation of nine taxoids-taxol 1 baccatin III 2, baccatin IV 3, taxusin 4, a C-14 oxygenated taxoid 5, I~-hydroxybaccatin 16, pentaacetoxy taxadiene 7, a dibenzoylated rearranged taxoid 8, 7-xylosyl-1 O-deacetyl-taxol C 9 and three phenolic compounds (-) seco-isolariciresinol 11, taxiresinol 12 and isotaxiresino...
