The existence of injured microorganisms in food and their recovery during culturing procedures is critical. Microbial injury is characterized by the capability of a microorganism to return to normalcy during a resuscitation process in which the damaged essential components are repaired. Injury of microorganisms can be induced by sublethal heat, freezing, freeze-drying, drying, irradiation, high...

Transfer of phage-related pathogenicity islands of Staphylococcus aureus (SaPI-s) was recently reported to be activated by helper phage dUTPases. This is a novel function for dUTPases otherwise involved in preservation of genomic integrity by sanitizing the dNTP pool. Here we investigated the molecular mechanism of the dUTPase-induced gene expression control using direct techniques. The express...

Distributed association rule mining is an integral part of data mining that extracts useful information hidden in distributed data sources. As local frequent itemsets are globalized from data sources, sensitive information about individual data sources needs high protection. Different privacy preserving data mining approaches for distributed environment have been proposed but in the existing ap...

Millions of people worldwide enjoy swimming pool activities every year. Traditionally, chlorine-containing chemicals have been used as the sanitizing agent. Some chlorine containing chemicals used include chlorine gas, sodium hypochlorite, calcium hypochlorite, lithium hypochlorite, and chlorinated isocyanurates. These chemicals enter the pool as a concentrated solution, or in the form of hypoc...

The mashup of microdata sources to form a data hub must fulfill a set of privacy preservation anonymity requirements that hinder data analysts to figure out sensitive information of the source datasets. This is relevant in a number of fields that include smart cities, electronic healthcare records and others. Linked data publishing architectures are not designed to adapt well to the requirement...

Failure in the cleaning process may form a conditioned film on the food processing surfaces which allows bacterial adherence. After the initial adhesion the microorganism start to multiplicate and results in a cell mass embedded in a complex exopolysaccharide matrix known as biofilm. Microorganisms in biofilm are more resistant to antimicrobial compounds than planktonic cells. That behavior all...

First there was Peter Toma, the idealistic, Hungarian-born inventor of the system who saw machine translation as a contribution towards achieving world peace. In recent years he has set up private university faculties in New Zealand and Argentina in those areas of the globe which are least likely to be affected by nuclear fallout. Then came Sadao Kawasaki, a Tokyo businessman who had made a few...

Cloud computing is a web based utility model. Cybercrimes effecting web based system are equally applicable in the cloud computing. Considering the sensitivity and the damage that can be caused by cybercrimes, this work is an effort to study the various cyber threats and methods to mitigate them. Firstly, it highlights the cloud usage as per the various services model (IaaS, PaaS, and SaaS) and...

Processing log data from a large distributed system is challenging. The collection and analyzing such data requires timely and accurate pre-processing and sanitizing the data, which is best done with a stream processing system. This paper explores ways to add control theory to a streaming log processing system to improve its accuracy and throughput in the face of varying loads and disturbances....
