In 1999, Pieprzyk and Qu presented rotation symmetric (RotS) functions as components in the rounds of hashing algorithm. Later, in 2002, Cusick and Stănică presented further advancement in this area. This class of Boolean functions are invariant under circular translation of indices. In this paper, using Burnside’s lemma, we prove that the number of n-variable rotation symmetric Boolean functio...

ABSTRACT Fusarium verticillioides, F. proliferatum, and Aspergillus flavus cause ear rots of maize and contaminate the grain with mycotoxins (fumonisin or aflatoxin). The objective of this study was to investigate the relationships between resistance to Fusarium and Aspergillus ear rots and fumonisin and aflatoxin contamination. Based on a previous study of 143 recombinant inbred lines from the...

In mobile environment, the asymmetric communication between mobile clients and server is a distinguishing feature. The conventional query processing mechanisms cannot be directly applied. In this research, we investigate the approach of using separate processing for read-only transactions (ROTs). Since ROTs have a significant proportion in several applications like traffic information service, ...

This study aims to examine the potential reasons for the current prevalence of the fusarium wilt in the oriental melon. Twenty-seven Fusarium isolates obtained from oriental melon greenhouses in 2010-2011 were identified morphologically and by analysis of elongation factor-1 alpha gene (EF-1α) and internal transcribed spacer (ITS) rDNA sequences as 6 Fusarium species (8 isolates of F. oxysporum...

To date the majority of work on the systemic fungicide phosphite (phosphonate) to control Phytophthora diseases has been conducted on horticultural crops. There is a paucity of work on the control of Phytophthora root and collar rots in natural plant communities. This paper gives an overview of studies conducted in Western Australia which examine the potential of using phosphite in plant commun...

Phytophthora is a microbial genus that includes species causing many diseases (Erwin and Ribeiro, 1996). These species infect and kill nearly all species of deciduous fruit trees. Phytophthora crown and root rots, which are caused mainly by P. cactorum, P. megasperma, P. citrophthora, P. cinnamomi, P. cambivora, P. syringae and P. cryptogea (Sarejanni, 1935; Kouyeas, 1971; Kouyeas, 1977; Flores...

Pathogenic effects of 6 Fusarium spp., viz., F. equiseti, F. longipes, F. scirpi (Section Gibbosum), F. oxysporum (Section Elegans), F. pallidoroseum (Section Arthrosporiella) and F. solani (Section Martiella) were studied on sunflower plants. Symptoms produced by Fusarium spp., were root-, collar-, stemand seedling rots, damping-off, stunting, wilting, tip burning and reduction in growth. Wilt...

In the internet environment, computers-based information systems are being employed to maintain large amounts of information to meet different users’ information requirements. The users interact with the system by inserting/updating/querying the required information. The information systems process the user requests by executing the update transactions (UTs) for inserts/updates and readonly tra...

In the emerging web databases and e-commerce scenario, information systems have to meet intensive information requirements from a large number of users. These information systems receive both update transactions (UTs) and read-only transactions (ROTs). A UT contains both read and write operations and an ROT contains only read operations. Designing efficient protocols to process ROTs is a resear...
