Corner reflectors form the major scattering centers in the radar signatures of ships, aircraft and vehicles. The radar cross section (RCS) reduction of these "flare spots" (corner reflectors) plays an ...

In this video we explore bending and shear stresses in beams. A bending moment is the resultant of bending stresses, which ...

Neuroscientists want to understand how individual neurons encode information that allows us to distinguish objects, like ...

Objective To analyse caesarean section (CS) using Robson 10-group classification system in an Ethiopian university hospital. Design Cross-sectional study. Setting A university hospital in eastern, ...

Examples are elm and mulberry tree leaves. Lobed Leaf: The margin has an indention or indentions that go less than halfway to the leaf midrib or midline. Maple and oak trees have lobed leaves.

When it comes to plants, a lot of great advice has been passed down through generations, but some gardening myths have ...

Radar cross sections for a variety of spherical and cylindrical scatterers having homogeneous dielectric or plasma shells are obtained by using both the exact boundary value solutions and approximate, ...

Natural biological tissues such as jellyfish integrate hierarchical architectures with multifunctionality (e.g., bioluminescence, mechanical resilience, and responsiveness), yet replicating such ...

This work aims to investigate the transverse free vibration of non-uniform beams with exponentially varying rectangular and circular cross-sections. When solving the governing equations for ...

The Heritage Structure of the Canadian ForcesCadet corps have been organized on military lines since at least 1861 and are supported by, but do not form part of, the CAF. The Junior Canadian Ranger ...

For each experimental repetition, digital images of stem and leaf cross sections were obtained using a photomicroscope (Olympus AX70) with a U-Photo system. In each leaf sample, it was measured the ...

In cross section, the subepidermal tissue is formed by isodiametric collenchyma cells, in which plasmodesmata are observed (Fig. 6 f). It should also be noted that numerous crystalliferous idioblasts ...
