Laan in (Ph.D Thesis, Tartu. 1999) introduced the principal weak form of Condition $(P)$ as Condition $(PWP)$ and gave some characterization of monoids by this condition of their acts. In this paper first we introduce Condition (G-PWP), a generalization of Condition $(PWP)$ of acts over monoids and then will give a characterization of monoids when all right acts satisfy this condition. We also ...

LEE, SUNG WON. A Probability Model for Random Fiber Breakage. (Under the direction of JOHN WILLIAM BISHlR). Two fundamental questions in connection with the random breakage of fibers in a breakage system are set forth: Given a fiber group of any particular length, (1) What is the probability that a fiber of the length groups breaks at all? (2) What is the probability that a fiber breaks into s ...

Protoplasts were isolated from five species of Gossypium. · Protoplast yield and viability were affected by incubation conditions, osmolarity, purification procedures, and cell source. Using an optimized procedure, highly viable protoplasts were isolated from cell suspensions, callus cultures, and leaf tissue of G. hirsutum, G. arboreum, G. k/otzschianum, G. harlmessii, and G. herbaceum. Protop...

This topic gives you basic ideas about the spectrums used in 3G and 4G communication systems. It also spreads light on the technologies used in both systems and their applications in current time. It allows one to understand the evolution of 4G from early 1G,its reasons and its effects.
