This study investigated genetic damage in paint workers mainly exposed to toluene as it is a major solvent used in paint thinners. Sister chromatid exchange (SCE) assay was used as biomarker of genotoxicity. Blood samples were collected from 30 paint workers and 30 control subjects matched with respect to age and other confounding factors except for exposure to toluene. SCE frequency was found ...

A system is introduced for the simulation of spray painting. Head mounted display goggles are combined with a tracking system to allow users to paint a virtual surface with a spray gun. Ray tracing is used to simulate droplets landing on the surface of the object, allowing arbitrary shapes and spray gun patterns to be used. This system is combined with previous research on spray gun characteris...

Recent advances in paint technology have guided the development of novel “ready-to-use” paint formulations in which microencapsulated insecticides, or active ingredients (AIs), are embedded in the paint matrix and gradually released on the surface of the dried paint [1]. It is argued that the slow-release mechanisms enable uniform AI surface concentrations with prolonged residual effect, as com...

Ovarian cancer is usually diagnosed at an advanced stage, rendering the possibility of cure unlikely. To date, no cost-effective screening test has proven effective for reducing mortality. To estimate the window of opportunity for ovarian cancer screening, we develop a branching process model for ovarian cancer growth and progression accounting for three cell populations: Primary (cells in the ...

.Frequent screening of suspicious skin pigmentations is of paramount importance since, at an early stage; skin cancer has a high cure rate and, in most cases, requires a simple treatment. In this paper, we present a newly methodology for early detection of skin cancer based on the used of image segmentation. This method is based on the use of the JensenShannon divergence of the histograms taken...

results two major themes were extracted from the analysis of the transcripts: “comprehensive caring commitment” and “patients’ medication grudge”. conclusions according to the findings, the nurses are in a unique position to care for people with ms; therefore they should be ready to provide high-quality patient care in ms patients. patients must be encouraged to study about their condition and ...
