شناخت عملکرد یک اکوسیستم طبیعی و آگاهی از پتانسیل آن، نیاز به آگاهی از مشخصهها و معرفهای خاکی و گیاهی دارد. ارزیابی ویژگیهای مهم خاک و پوشش گیاهی میتواند ما را از تواناییهای موجود مرتع آگاه نموده و تعیین وضعیت آن را میسر سازد. هدف از این مطالعه مقایسه و تعیین عملکرد شاخصهای سطح خاک در لکههای اکولوژیک موجود در دو دامنه شرقی و غربی مراتع لیشتر در استان کهگیلویه و بویراحمد است. بدین منظور د...
in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...
UNLABELLED BACKGROUND Immunostimulatory therapy is now being recognized as an alternative to conventional chemotherapy for a variety of disease conditions, involving the impaired immune response of the host.
