Mitotic inheritance of gene function is obligatory to sustain biological control. Emerging evidence suggests that epigenetic mechanisms are linked to transmission of cell fate, lineage commitment, and maintenance of cellular phenotype in progeny cells. Mechanisms of epigenetic memory include gene silencing by DNA methylation, transcriptional regulation by histone modifications, regulation of ge...

background: nowadays medical equipment plays an important role in the treatment and in the medical education. using outdated preventive maintenance (pm) system may cause problems in the cutting edge medical equipment, nervous system disease’s equipment (in diagnosis and treatment) which are crucial for every medical center. based on above facts we focused on nervous system treat units’ equipmen...

The Walkway Management System (WMS) uses geographic information system (GIS) software to calculate an estimate for the level of maintenance required for walkway segments. It then assists the user in prioritising the maintenance on segments of the walkway that require repair. The development of the WMS is a cooperative effort between a team of researchers at Lincoln University and Department of ...

by the appropriate use of information technology, organizations can achieve sustainable competitive advantages. this technology because of including some characteristics such as being up-to-date, fast and precise and having different geographic localities all the time, has improved organizational efficiency, effectiveness and performance. in this article, we intend to investigate the role and e...

The purpose of this tutorial is to explain and illustrate an approach to the quantitative modelling of molecular interaction networks which departs from the usual notion of (bio-) chemical reaction. This tutorial is self-contained and supposes no familiarity with molecular biology. We shall use a modelling language called Kappa [1], but much of what we will present equally applies to the larger...

Interestingly, managing corporate information systems evolution and maintenance that you really wait for now is coming. It's significant to wait for the representative and beneficial books to read. Every book that is provided in better way and utterance will be expected by many peoples. Even you are a good reader or not, feeling to read this book will always appear when you find it. But, when y...

The Marine Region of the Hong Kong Police Force is responsible for policing the waters and 262 islands that lie within the 1,651 square kilometers of the Hong Kong Special Administrative Region (HKSAR). In addition to routine policing, the Marine Region has responsibilities in other diverse areas like quarantine, immigration, conservancy, and also port and maritime regulations (Hong Kong Police...

We describe the design of a tenant interface for energy and maintenance systems (TIEMS) in commercial buildings. TIEMS is designed for use by occupants (tenants) of commercial buildings. Our hypothesis is that by allowing tenants access to information from the energy and maintenance systems and by giving them some control over these systems, energy and maintenance performance can be improved. W...

This article argues that information systems maintenance is a more complex and integrated task than portrayed in the literature. It involves not only the maintenance of the applications software, but also all the other elements in an operational system. The literature relating to the maintenance of each element is reviewed to reveal substantial underdevelopment i some areas and fragmentation be...
