Inside the nucleus, DNA replication is organized at discrete sites called replication factories, consisting of DNA polymerases and other replication proteins. Replication factories play important roles in coordinating replication and in responding to replication stress. However, it remains unknown how replicons are organized for processing at each replication factory. Here we address this quest...

China was attacked by a serious influenza A (H7N9) virus in 2013. The first human infection case was confirmed in Shanghai City and soon spread across most of eastern China. Using the methods of Geographic Information Systems (GIS) and ecological niche modeling (ENM), this research quantitatively analyzed the relationships between the H7N9 occurrence and the main environmental factors, includin...

BACKGROUND Coffee processing causes organic dust exposure which may lead to development of respiratory symptoms. Previous studies have mainly focused on workers involved in roasting coffee in importing countries. This study was carried out to determine total dust exposure and respiratory health of workers in Tanzanian primary coffee-processing factories. METHODS A cross sectional study was co...

In this paper we consider a production enterprise that has several factories. This enterprise manufactures several diierent types of products on a produce to order basis. The level of operational control available within each factory with respect to scheduling is limited. Hence, it is of interest to nd the appropriate allocation of the diierent types of products to the diierent factories. In a ...

sugar beet roots and attached soil are usually transferred to sugar factories for processing ,then the roots are washed by pressurized water. muddy water as waste flows in canal and is used to irrigate fields. the possibility of occurrence and fluctuations of the pathogenic organisms in waste were studied in 2005. the samples were collected from waste water once a week. isolation of pathogens w...
