HISTOLOGICAL AND ULTRASTRUCTURAL CHARACTERIZATION OF THE DORSO-VENTRAL SKIN OF THE JUVENILE AND THE ADULT STARRY PUFFER FISH (AROTHRON STELLATUS, ANONYMOUS 1798)

Abstract Background The starry puffer fish (Arothron stellatus, Anonymous, 1798) is a poisonous tetradontidae fish inhabiting the Red sea.The skin constitutes an important defense against any external effects.The study aims to characterize the dorso-ventral skin of the juvenile and the adult starry puffer fish using light and scanning electron micr

We study a heretofore unexamined type of product differentiation, horizontally differentiated products with differential costs, and apply the analysis to retail pricing of fluid milk products.The theoretical models yield unique predictions for orly impressions the relationship among prices of the four horizontally differentiated fluid milk products

The efficacy of pesticide applications is related to the spread and evaporation time of the droplets deposited on the target.This study evaluates the evaporation of spray droplets containing thiamethoxam and adjuvants on different surfaces and at different levels of relative air humidity.A climate controlled chamber was set up with a digital micros
