detection of volatile compounds of medicinal plants with some nano-sorbents using modified or new methodologies and investigation of antioxidant activity of their methanolic extracts
in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...
Improvement of hatchability of chicken eggs injected by blastoderm cells.
In our first experiment, we studied the effect of injection method of blastoderm cells (BC) into the subgerminal cavity of White Leghorn embryos on hatchability of chicken chimeras. Freshly laid eggs were injected through a hole made in the equatorial plane of the eggshell (Method A). In Method B, eggs were stored pointed end down for 5 to 7 d prior to injection, and a hole was cut in the blunt...
متن کاملThe effect of eggshell thickness on hatchability of quail eggs
BACKGROUND AND AIM The aim of the successful incubation period is to achieve maximum health chicks in each batch. Therefore, all factors affecting incubation have to be investigated in detail. This study investigated the effect of eggshell thickness on hatchability of quail eggs. MATERIALS AND METHODS A total of 1415 eggs were collected from the same flock at the ages of 23 and 41 weeks. Two ...
متن کاملEcological and Social Factors Affecting Hatchability of Eggs
--Hatchability, defined as the proportion of eggs surviving to the end of incubation that hatch, varies among populations of birds. Here, I examine the effects of a variety of variables on hatchability in a comparative analysis of 155 studies of 113 species. Of the ecological nd geographical variables considered, latitude, diet, and nest type explain a significant amount of the variance in hatc...
