Flight Flutter Testing of Supersonic Interceptors

A summary is presented of experiences in connection with flight flutter testing of supersonic interceptors. The planning and operational aspects involved are described along with the difficulties encountered, and the correlation between measurement and theory. Recommendations for future research and development to advance the science of flight flutter testing are included

The Angel Saint

This is a small tract relating the life and early history of St. Thomas Aquinas, as the patron of Catholic Schools, Colleges and Universities. The tract was meant for wide dissemination among the public for promoting the Catholic Church and in explaining St. Thomas’ part in shaping the Church’s role in education.https://digitalcommons.providence.edu/catholic_documents/1017/thumbnail.jp

Politics and Fiscal Policy under Lemass: A Theoretical Appraisal

Lemass rejected Whitaker’s recommendations that direct taxes be reduced and public investment shifted from social to productive areas. This was arguably done for political reasons and because Lemass believed that it might be possible to establish a social partnership deal of the type that Eichengreen has argued to have played a crucial role in post-war European convergence on US living standards. Such a bargain could not be reached under Ireland’s industrial-relations system however. The present paper contrasts the two systems and shows the adverse employment, investment and growth effects that such attempts would have had in Ireland.

Научно-практические мероприятия Украинского Информационного Центра «Наука. Техника. Технология»

L'auteur présente ici un rappel des recherches effectuées depuis 1972 en Côte d'Ivoire sur l'haploïdie chez les cacaoyers, décrit les caractères phénotypiques de ces cacaoyers puis les travaux qui ont permis d'aboutir à leur diploïdisation. L'obtention de cacaoyers homozygotes diploïdes, fertiles, en nombre pratiquement illimité et de diversité génétique suffisante apparaît désormais possibl

Complex Simplicity

I was born the only American in my West Indian, Guyanese family. My culture played a large part in how I was brought up, and in turn, shaped the person and artist I have become. In my work, I like for my viewers to get a personal feel for what it is like to be West Indian American. My work is a cultural record of people, places, and things. I capture small, special moments because I know that they will never be recreated. My camera’s viewfinder has always been filtered through my eye as a child of immigrant parents. I use photography as my first step in creating and recording ordinary, everyday things. Photographs are captured where I feel most American eyes would by-pass or overlook their importance. However, my work must also involve my hand. Therefore, through my mark making, whether I am drawing, painting, collaging, stitching or using software, I add and subtract from my original photos. By manipulating my images, I change and emphasize a single, fleeting moment into something permanent and significant

Note sur l'utilisation d'un marqueur génétique dans les recherches d'haploïdes chez le cacaoyer (Theobroma cacao L.)

Le caractère appelé "axil spot" (tache violette à la jonction du pétiole et de la tige) a été utilisé dans la recherche d'haploïdes par pollinisation différés chez Theobroma cacao: des fleurs d'un haut-Amazonien, récessives pour le facteur de production du caractère "axil spot", ont été fécondées avec un pollen du clone C 305 homozygote pour les allèles dominants de ce caractère. Un seul cas d'haploïdie a été relevé parmi les plantules de phénotype maternel issues des pollinisations effectuées 24h après épanouissement, mais aucun cas parmi les plantules issues des pollinisations faites sur bouton floral. Le caractère "axil spot" est un marqueur génétique efficace pour ce type de recherche
