This study aims to determine the Importance Value Index (INP), Vegetation Diversity Index, and abiotic factors in herbal strata Bukit Gatan, Musi Rawas Regency. Determination of Herbs Strata Gatan Regency using point intercept method, which uses touch rods that are below line. research was made into 3 areas, namely area A (1-10 stands), B stands) C then data were analyzed descriptively quantita...

Iran's mud volcanoes are clearly visible on the coastal plains of the Oman and Caspian Seas. There are 30 Gatan Mud Volcanoes located in the southeast of Iran: 15 of which are located between Jask and Minab in Hormozgan province, nine are between Chabahar and Jask Ports, and another six are between Chabahar and the Iran-Pakistan border in Sistan and Balouchestan Province. After some studies and...

Using single crystal V2O5 as a sample, we tested the performance of the new aberration corrected GATAN spectrometer on a monochromatised 200 kV FEG FEI (S)TEM. The obtained V L and O K ELNES were compared with that obtained in a common GATAN GIF and that in the new spectrometer, without monochromatised beam. The performance of the new instrumentation is impressive: recorded with an energy-resol...

A new generation of direct electron detectors for transmission electron microscopy (TEM) promises significant improvement over previous detectors in terms of their modulation transfer function (MTF) and detective quantum efficiency (DQE). However, the performance of these new detectors needs to be carefully monitored in order to optimize imaging conditions and check for degradation over time. W...

abstract gatan has distributed in the main rivers in khoozestan province and there are few researches on propagation and reproductive system of this species. therefore, this study has focused on using of activating solutions on sperm activity and fertilization capability in gatan fish in comparison with grass carp. in this research, 5 activating solutions together with workshop water and distil...

A novel approach to observe the interaction between magnetic domain wall and nanoscale microstructural features is demonstrated. The method is based on Focault mode Lorentz microscopy and utilizes a Gatan energy image filter to provide additional magnification. A postexperimental image processing technique was applied to separate lattice diffraction from that induced by magnetic domains. The ef...

The cryo scanning electron microscopy (cryo-SEM) as well as high-pressure-freezing (HPF) belongs to cutting edge techniques in electron microscopy of hydrated samples [1]. However, their combination is not always easily applicable. Here, we present a way of combining high-pressure-freezing using EM PACT2 (Leica Microsystems) that fixes hydrated samples on a 1.4 mm sapphire discs and high resolu...
