hazard
Hazard function and characterizations on distribution tails of nonnegative random variables
      
In this paper we pay special attention to the hazard rate function re(x) of Fe(x), which is also called the equilibrium hazard rate (E.H.R.) of F(x).
      
All these were analyzed in 105 cases along with the follow-up data and tested by log rank and COX hazard proportional model.
      
The COX hazard proportional model revealed that advanced clinical stage (P = 0.001), large tumor size (P = 0.001), a high mitotic index (P = 0.002) and the high risk grade (P = 0.018) indicated a poorer prognosis in gastric GIST.
      
A possibility is considered for predicting the radiation hazard onboard orbital stations upon the appearance of solar proton events using dosimeter data from a geosynchronous orbit.
      
Responses of Unio tumidusto Mixed Chemical Preparations and the Hazard of Synecological Summation of Anthropogenic Effects
      
The Hazard of a Two-Level Synergism of Synecological Summation of Anthropogenic Effects
      
Identification of a New Type of Ecological Hazard of Chemicals: Inhibition of Processes of Ecological Remediation
      
Extremely high contents and organic mode of Sb occurrence make it possible to consider Ge-bearing coals of the Pavlovka deposit not only as a complex raw material suitable for the extraction of Sb, but also as a potential source of ecological hazard.
      
The database will provide information that is of interest for the development of microbial ecology and biotechnology, in particular, for the prediction of biological hazard from the application of transgenic strains.
      
The article reports on the impurity composition and toxicological hazard of the wastewater from production of chemicothermomechanical mass for manufacturing pressboard and different types of paper.
      
Low Efficiency of Short-Term Tests in the Assessment of the Potential Mutagenic Hazard of Chemical Compounds to Mammals
      
The data on the allele frequencies and the relative hazard values in Russians, Ukrainians, and Belarussians can be used as the predictors of AIDS onset and progression rate in HIV-1-infected individuals from the populations studied.
      
A nonstochastic heritable cell lethality effect was for the first time used in the practice of biotesting in a model of Saccharomyces yeasts for predicting the hazard of low mutagen doses.
      
Our finding of a significant elevation of CA and MN frequencies in peripheral lymphocytes from smokeless tobacco consumers demonstrated a potential cytogenetic hazard associated with Maras powder exposure.
      
The results of this study suggest a high pathogenic potential of the isolated halophilic vibrios, which are an epidemic hazard to marine invertebrates and to humans.
      
A technique for estimating the hazard presented by the flaws in railway tanks based on detection of AE signals is discussed.
      
The degree of hazard due to a aw has been estimated in experiments basing on the recorded AE energy.
      
Assessment of Hazard Due to Flaws in Metallic Structures Detected by the AE Method
      
The paper contains analytical expressions for calculating rejection levels and a practical example of a calculation of the degree of hazard caused by a aw detected by the AE method in an oil-gasoline tank.
