Military strategies of the Islamic Republic of Iran against American military threats

Purpose: The main purpose of this research is to examine the military threats of the United States and present the military strategies of the Islamic Republic of Iran against them.Method: The type of research is applied, and the necessary information is obtained from the study of documents, interviews with experts and questionnaires, and a descriptive method with a mixed approach has been used. The overall statistical population of the research is 70 people and the sample size is consistent with the statistical population and all the numbers have been determined. In order to collect and analyze data, in addition to taking samples from library studies and conducting expert interviews, using document analysis and elite analysis methods, descriptive and inferential statistics methods have also been used.Results: The number of 7 main strategies was calculated based on 73 selected research factors (19 strength factors, 9 weakness factors, 10 opportunity factors and 35 threat factors) relying on the provided partial strategies.Conclusion: The result of the vector on the axis of Cartesian coordinates indicates that the competition of the Islamic Republic of Iran is more focused on strengths than opportunities

Structural characterization and thermal behavior of a gum extracted from Ferula assa foetida L.

International audienceThe gum asafoetida, an oleo-gum-resin from root of Ferula assa foetida, was extracted through alcoholic procedure followed by water extraction and then biochemically characterized using colorimetric assays, Fourier infrared spectroscopy, gas chromatography coupled to mass spectrometry, and 1D and 2D nuclear magnetic resonance. The gum was mainly composed of carbohydrates (67.39% w/w) with a monosaccharide distribution of 11.5: 5.9: 2.3: 1 between Gal, Ara, Rha and GlcA (molar ratio) and proteins (arabinogalactan protein). The polysaccharide consisted of a (1 → 3)-β-d-galactan backbone ramified predominantly from O-6 but also from O-4 and O-4,6. Side chains included terminal-α-l-Araf, terminal-α-l-Rhap, (1 → 3)-α-l-Araf, (1 → 5)-α-l-Araf, terminal-β-d-Galp, β-d-GlcA and traces of (1 → 4)-β-d-GlcA. X-ray diffraction pattern showed a semi crystalline microstructure. Thermal behavior of the gum was evaluated by thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC) revealed temperatures below and upper 200 °C as dominant regions of weight loss
