Genetic analysis of the Laminin A (LamA) gene in Drosophila reveals that distinct classes of sensory axons have different requirements for extracellular matrix (ECM) containing laminin A versus epithelial cell surfaces. In the eye-antenna imaginal disc, the nerve from the three simple eyes (ocelli) to the brain is pioneered by a population of transient ocellar neurons whose axons extend on an E...

The spatially restricted activities of achaete (ac) and scute (sc) are thought to define proneural clusters of potential sensory organ precursor cells in the imaginal discs of Drosophila. These genes encode transcriptional regulators of the basic helix-loop-helix (bHLH) class. We have found that direct, positive transcriptional autoregulation by the ac protein and cross-regulation by sc are ess...

Aim: To assess the morphology of toothbrush bristle end by using Light Microscope and to evaluate the percentage of rounded-end bristles which are considered to be acceptable as recommended by American Dental Association. Materials and Methods: Three leading toothbrushes brands available in India were included for the present study. The bristles were removed and mounted on a glass slide and sec...

This study considers an analytical method to detect the damage location from the moment diagram calculated by the external forces and the forces required for obtaining the same deflections as the measurement deflections. The measured deflections must be a part of displacements to restrict the static behavior of the damaged beam. The constraint forces acting at measurement points are derived by ...

Synopsis: With long-term deflection being a critical design criterion, accurate deflection prediction is an important aspect of slab design. The many factors that influence long-term deflections and their interdependence as well as variability in material strengths and characteristics make this a challenging problem. Most building codes and standards provide methods and formulae to account for ...

Intraspecific variation in adult body mass can be particularly high in some insect species, mandating adjustment of the wing's structural properties to support the weight of the larger body mass in air. Insect wings elastically deform during flapping, dynamically changing the twist and camber of the relatively thin and flat aerofoil. We examined how wing deformations during free flight scale wi...

The aim of this paper is to compare the static deflections and stress results of layered and functionally graded composite beams under static load. In the comparison study, the results obtained for a cantilever beam under point load. The Timoshenko beam and the Euler-Bernoulli beam theories are used in the beam model. The energy based Ritz method is used for the solution of the problem and alge...
