Specimens for cross-sectional TEM were prepared using the procedure of Helmerson and Sundgren [21].
Specimens for cross-sectional transmission electron microscopy [TEM] studies were prepared by mechanical grinding and polishing (approximately 10-μm thick) followed by Ar-ion milling using a Gatan Precision Ion Polishing System (PIPS™ Model 691, Gatan, Inc., Pleasanton, CA, USA). Figure 1 shows a schematic outline for the present layer-by-layer synthesis of the TiOPDA films.
However, Edgar T. Wherry was able to locate the Delaware colony, thought lost, in 1919, and send specimens for cross-pollination with specimens from the Pennsylvania colony.
Four P0-, 13 F1-, and 404 F2 specimens of cross AB were genotyped at those 411 markers, for which all alleles were strain specific in the P0.
All blood specimens for our cross-sectional study were obtained within 12 weeks of the first reported case of hemorrhagic fever in Garissa District.
Additionally, given the disparate estimates of HPV prevalence in breast tumors, future studies might incorporate more rigorous control measures such as cutting sections of HPV negative tissues for DNA extraction and PCR in between successive breast tumor specimens to test for cross-contamination with HPV positive samples.
This analysis is important for guaranteeing the material property for each test specimens with varying cross sectional ratio, inner and outer diameter of the GFRP hybrid bars.
The cross-sectional specimens for TEM study were prepared by Ar ion beam milling at 4 kV/20 μA and at an angle of 4° with respect to the sample surface.
Specimens with crossing points greater than 30 were considered negative for HSV.
The specimens for HAADF-STEM were prepared in cross-section by mechanical grinding and Ar+ ion milling using a precision ion polishing system (PIPS), with beam tilts of − 3° and + 4° and beam energy between 2.8 and 3.0 kV.
The fatigue failure modes consist of the fracture along the circumference or along the direction of width for tensile-shear specimens and pullout or fracture along the direction of width for cross-tension specimens.
