BACKGROUND In 2013, an unusually high incidence of biliary tract cancer among current or former workers of the offset color proof printing department of a printing company in Osaka, Japan, was reported. The purpose of this study was to examine whether distance from the printing factory was associated with incidence of biliary tract cancer and whether incident biliary tract cancer cases clustere...

The MAC (Medium Access Control) protocols can be roughly categorized into three broad classes [16]. The fixed assignment set will have schemes like TDMA, CDMA and FDMA. These protocols lack the flexibility in allocating resources and thus have problems with configuration changes. This makes them unsuitable for dynamic and bursty wireless packet data networks. The random assignment class consist...

N EW understanding of the natural history of heart disease and better methods of treatment are reducing the aura of fear traditionally surrounding the cardiac patient. At the same time, modern technology is steadily lowering the physical demands of factory work, so that it is now evident that a majority of urban patients with heart disease can work safely.1 The physician, who is increasingly ca...

The paper describes the CERN approach for a proton driver for a Neutrino Factory. Two main layouts are presented: the so-called CERN Reference Scenario, based on a 2.2 GeV linac and an alternative one, based on a 30 GeV synchrotron. Both produce bunches of 1 ns (r.m.s.) and a beam power of 4 MW. Presented at NUFACT'00, Monterey, California, USA 22-26 May 2000 Geneva, Switzerland September 2000 ...

BACKGROUND In urban China, more single women are becoming pregnant and resorting to induced abortion, despite the wide availability of temporary methods of contraception. We developed and piloted a workplace-based intervention to promote contraceptive use in unmarried female migrants working in privately owned factories. METHODS Quasi-experimental design. In consultation with clients, we deve...

Over the past 25 years, the machine-part cell formation problem has been the subject of numerous studies. Researchers have applied various methodologies to the problem in an effort to determine optimal clusterings of machines and optimal groupings of parts into families. The quality of these machine and part groupings have been evaluated using various objective functions, including grouping eff...

Customers increasingly want to have individual products with costs comparable to mass-produced goods. For manufacturers this leads to small batches and many variants associated and a high productivity at the same time. Therefore future production systems must be adaptive, resource-efficient and user friendly. Such a smart factory is an intelligent socio-technical production system based on info...

I ndonesia has one of the highest ratios of maternal mortality in Southeast Asia (359 deaths per 100,000 live births in 2012), according to the latest Indonesia Demographic and Health Survey. The Indonesian government provides free maternal and child health services, but for many of the twenty-five million female workers who are of reproductive age, these services are not available during their...

background: cement production is associated with heavy metal emissions and environmental pollution by cement dust. the degree of contamination of drinking water sources by major and trace elements present in cement dust generated by united cement factory (unicem) is still uncertain. this study estimated the element content of ground and surface water samples (hand-dug wells, boreholes and strea...
