Vision is energetically costly to maintain. Consequently, over time many cave-adapted species downregulate the expression of vision genes or even lose their eyes and associated eye genes entirely. Alternatively, organisms that live in fluctuating environments, with different requirements for vision at different times, may evolve phenotypic plasticity for expression of vision genes. Here, we use...

Henna leaves extract (Lawsonia inermis L) is used as a corrosion inhibitor in St37 steel soaked 3% HCl corrosive medium. To find out the effect of concentration on rate steel, variation 0, 3, 5, 7 and 9%. Corrosion testing done by mass loss method. was tested low carbon with without inhibition henna for 6 days. The results showed that greater used, would decrease ability to inhibit increase. gr...

In the present study, the removal of lead (II) ions from aqueous solutions was investigated by powdered Henna. Henna is a herbal material that can dramatically adsorb metal ions. Adsorption experiments were carried out in a batch system at room temperature. Then, the equilibrium concentration of each sample was analyzed by atomic adsorption device. The effects of various parameters such as ...

: Travel writing becomes an object of scholarly scrutiny thanks to Edward Said’s Orientalism in which he contends that travel narratives are not the objective portraits Oriental peoples and loci, but collude with justify foster Western Empires. Nonetheless, scholars such as Behdad Blanton disagree view, asserting writers can transcend rigid norms Orientalism. Thus, by employing Behdad’s Blanton...
