IN VITRO MULTIPLICATION OF CASSAVA VARIETIES

Multiplication of Fibroblasts in Vitro

I t is well known that the life of tissues cultivated in the plasma of an adult animal lasts only for a certain period of time. 10 years ago, one of the writers attempted to prevent the death of the tissues living under these conditions. 1 I t was supposed that ff their waste products were removed by frequent washings, the cells would multiply indefinitely. Every few days, fragments of embryoni...

The Influence of Socio-Economic Variables of Farmers on their Choice of Cassava Varieties in Kogi State, Nigeria.

This study examined the influence of socioeconomic variables of farmers on their choice of cassava varieties in Kogi State of Nigeria. A total of 360 cassava farmers were selected through multi-stage random sampling procedure. Data collected through structured questionnaire were analyzed using descriptive statistics, customer-buying behavioral model and dynamic programming model. The results sh...

Abelian Varieties with Complex Multiplication (for Pedestrians)

(June 7, 1998.) This is the text of an article that I wrote and disseminated in September 1981, except that I’ve updated the references, corrected a few misprints, and added a table of contents, some footnotes, and an addendum. The original article gave a simplified exposition of Deligne’s extension of the Main Theorem of Complex Multiplication to all automorphisms of the complex numbers. The a...

Black Hole Attractor Varieties and Complex Multiplication

We show how Moore’s observation, in the context of toroidal compactifications in type IIB string theory, concerning the complex multiplication structure of black hole attractor varieties, can be generalized to Calabi-Yau compactifications with finite fundamental groups. This generalization leads to an alternative general framework in terms of motives associated to a Calabi-Yau variety in which ...
