On the mechanism of phenotypic conversion of human cervical adenocarcinoma HeLa cells surviving infection by influenza B virus: Potential implications for biological management of adenocarcinomas
(2008)
We infected HeLa cells with low (10(-9) units), medium (10(-6) units), and high (10(-2) units) influenza B titers and compared the resulting human papilloma virus (HPV), retinoic acid receptor a subunit (RAR alpha) and ...
Comparison of quadratic and non-linear programming (QP and NLP) optimization models in groundwater management
(2004)
This project is concerned with the comparison of two algorithms used in groundwater management models based on Quadratic Programming (QP) and Non-linear Programming (NLP) models,. A quadratic objective function is used and ...
Explicit extension of the p-y method to pile groups in sandy soils
(2014)
The method of "p-y" curves has been extensively used, in conjunction with simplified numerical methods, for the design and response evaluation of single piles. However, a straightforward application of the method to assess ...
DNA damage and repair efficiency in lymphocytes from schizophrenic patients
(2004)
In the present study we examined schizophrenic patients' lymphocytes sensitivity to the effects of external factors, such as hydrogen peroxide and gamma-irradiation and also their repair efficiency with the comet assay. ...
Modeling and solution approach for the environmental traveling salesman problem
(2014)
We consider the environmental traveling salesman problem in a connected graph driven by a cost function describing the impact of environmental externalities over the routes. The resulting problem is the asymmetric non-Euclidean ...
Effect of dietary non-starch polysaccharide solubility and inclusion level on gut health and the risk of post weaning enteric disorders in newly weaned piglets
(2007)
The objective of this experiment was to investigate the effect of non-starch polysaccharide (NSP) solubility and inclusion rate on gut health and development, performance and risk of post weaning enteric disorders (PWED) ...
VIPSec defined
(2008)
Secure end-to-end information exchange is a constant challenge in electronic communications. Novel security architectures and approaches are proposed constantly, to be followed by announcements of sophisticated attack ...
Wedge indentation of elastic-plastic layered substrates: Designing against contact-induced plasticity
(2009)
The present paper investigates the indentation of plastically graded substrates by wedge indenters. Substrates made of graded materials are often encountered in nature or are artificially produced. The variation of the ...
'THE JUNTA CAME TO POWER BY THE FORCE OF ARMS, AND WILL ONLY GO BY FORCE OF ARMS' POLITICAL VIOLENCE AND THE VOICE OF THE OPPOSITION TO THE MILITARY DICTATORSHIP IN GREECE, 1967-74
(2011)
This article addresses the question of political violence and focuses on opposition groups during the military dictatorship in Greece (1967-74). It examines the diverse ideas about the use of violence among the opposition ...
An inhomogeneity correction algorithm for irregular fields of high-energy photon beams based on Clarkson integration and the 3D beam subtraction method
(2006)
A number of treatment-planning systems still use conventional correction methods for body inhomogeneities. Most of these methods (power law method, tissue-air ratio (TAR), etc.) consider only on-axis points, rectangular ...
