BACKGROUND Sickness absence (SA) is affected by societal factors. Increasing socioeconomic stress may cause or worsen mental health disorders, which are among the most frequent causes of SA. Employees may also be more cautious about being absent, for example in times of poor economy. AIMS To monitor the incidence of SA due to mental health disorders in the Netherlands from 2001 to 2010. MET...

1 This guidance has been produced by the Health and Safety Executive. It provides advice and information on the selection, installation, use and maintenance of industrial flammable gas detectors. It is aimed at process engineers and managers and others concerned with the use of flammable gas detectors. It is not intended for specialist instrument engineers or those seeking detailed technical in...

In 2005 Schneider Electric's Innovation Department began running tests to assess the performance of ZigBee, a ready-to-use wireless technology with ultra-low power consumption. The department's aim was to gauge ZigBee's performance in helping to ensure the continuous operation of machines and processes, even in harsh industrial conditions, while contributing to a greener environment. The cost-r...

Methane production by fermentation is a complex biochemical process, in which micromolecular organic substances are broken down anaerobic bacteria into simple stabilized chemicals—mainly methane CH4 and carbon dioxide CO2. The matter of the slurry consists mainly fats, proteins carbohydrates. As result changes process decomposition, some this mineralized to chemical compounds. Cattle pig husban...

In this article, new techniques and technologies have been tried and tested in the installation and commissioning of Roller Home industrial robots, in order to produce a Tiba car with a focus on cost reduction. Due to the fact that press equipment for automobile parts requires a lot of expenses, it was decided to use robots with the same function of roller to reduce costs and increase the q...

This study used an ECM to analyze the determinants of agricultural land expansion in Nigeria. Results show that at first differencing, Augmented Dickey Fuller test indicated stationarity for all the variables (p< 0.05) and there were 7 cointegrating vectors using Johansen test. The dynamic unrestricted short-run parameters of permanent cropland growth rates (68.62), agricultural production inde...

This study estimates an econometric model that incorporates the linkages among agriculture, manufacturing, service and trade sectors using a vector error correction model for Poland and Romania. Three cointegrating vectors for Poland and one for Romania confirm that the different sectors in the Poland and Romania moved together over the sample period, and for this reason, their growth rates are...

The number of large industrial plants being planned and constructed in Japan has increased tremendously in recent times. By reducing the construction costs involved in the development of these plants, authors can reduce the initial investment required, thereby ensuring a more economical use of monetary resources. However, construction work still requires considerable skill and labor. Hence, it ...
