OBJECTIVES To estimate the proportion of pleural mesothelioma cases that can be attributed to asbestos exposure in France including non-occupational exposure. METHODS A population-based case-control study including 437 incident cases and 874 controls was conducted from 1998 to 2002. Occupational and non-occupational asbestos exposure was assessed retrospectively by two expert hygienists. ORs ...
OBJECTIVES The ototoxicity of occupational exposure to toluene plus noise was investigated in a longitudinal study in rotogravure printing and existing findings in the literature were evaluated. MATERIAL AND METHODS The study comprised four repeated examinations during 5 years and started with 333 male workers. Lifetime weighted average exposures (LWAE) to toluene and noise were determined fr...
This paper presents a behavioral representation for the class of Nyquist rate A/D converters that captures the nominal behavior , as well as all the statistical variations. To describe noise eeects we use a joint probability density function. To describe behavioral eeects due to process variations we use a covariance matrix, t. Applications of the model include identiication of important A/D er...
The Oct-3/4 transcription factor is a member of the POU family of transcription factors and, as such, probably plays a crucial role in mammalian embryogenesis and differentiation. It is expressed in the earliest stages of embryogenesis and repressed in subsequent stages. Similarly, Oct-3/4 is expressed in embryonal carcinoma (EC) cells and is repressed in retinoic acid (RA)-differentiated EC ce...
Tapping into the communication between two hosts on a LAN has become quite simple thanks to tools that can be downloaded from the Internet. Such tools use the Address Resolution Protocol (ARP) poisoning technique, which relies on hosts caching reply messages even though the corresponding requests were never sent. Since no message authentication is provided, any host of the LAN can forge a messa...
Spoofing with falsified IP-MAC pair is the first step in most of the LAN based-attacks. Address Resolution Protocol (ARP) is stateless, which is the main cause that makes spoofing possible. Several network level and host level mechanisms have been proposed to detect and mitigate ARP spoofing but each of them has their own drawback. In this paper we propose a Host-based Intrusion Detection syste...
Introduction: exposure to noise pollution leaves Different effects on human. Goal in this Paper is the prioritizing methods of control and reduce noise pollution in Larestan cement Factory using analytical hierarchy process (AHP). Methods: For screening criteria and methods used in AHP technique, Delphi method was used. After polling of 15 experts, 8 criteria and 9 methods was selected from ...
Noise induced hearin gloss (NIHL) is one of the most important occupational disease world wide. NIHL has been found potentiate by simultaneous carbon monoxide (CO) exposure. Free radicals have been implicated in cochlear damage resulted from the exposure to noise and due to the CO hypoxia. This study examined whether α-tocopherol administration , as a free radical scavenger, causes the attenuat...
In this paper, the performance of a cloud radio access network (CRAN) is analysed, which consists of multiple randomly distributed remote radio heads (RRHs) and a macro base station (MBS). Different from previous works on CRAN where Poisson Point Process (PPP) is used to model spatial distribution of RRHs, a more realistic Matérn Hard-core point process (MHCPP) model is adopted in this work. To...
