Determination of vitamins in feeds

The vitamins, though required in small amounts in the diet, play major roles in growth, physiology and metabolism of the animal. Their absence in the diet causes major deficiency syndromes. Also, the vitamins should be present in optimum levels in the diet; any excess in certain vitamins in the diet causes pathological symptoms and inhibit growth. Therefore, the determination of the amount of different vitamins present in the diet is very important

Preparation of artificial diets for nutritional studies

The H 440 standard reference diet of Halver (1969) has* proven satisfactory for use with a variety of species of fishes. If this exact formula does not prove satisfactory for growth and survival of the test fish, slight modifications of clearly explained ingredient changes still permit meaningful comparisons of the test fish results with other species

Monoid automata for displacement context-free languages

In 2007 Kambites presented an algebraic interpretation of Chomsky-Schutzenberger theorem for context-free languages. We give an interpretation of the corresponding theorem for the class of displacement context-free languages which are equivalent to well-nested multiple context-free languages. We also obtain a characterization of k-displacement context-free languages in terms of monoid automata and show how such automata can be simulated on two stacks. We introduce the simultaneous two-stack automata and compare different variants of its definition. All the definitions considered are shown to be equivalent basing on the geometric interpretation of memory operations of these automata.Comment: Revised version for ESSLLI Student Session 2013 selected paper
