According to a criticaster Wehkamp owns “fossil COBOL in rock”. In 1995 Wehkamp decided to get rid of her mainframe. Her strategy was to stop development on her GCOS8 platform. The idea was that the mainframe would dry and eventually could be carried to her grave. Unfortunately this strategy did not work. In fact complexity has grown beyond control. In the first part of the talk we will give a ...

 Background: The aim of this study was to evaluate the physical and chemical quality of groundwater in the villages of Qom province during summer 2014, and to compare the results with Iran’s Standard No. 1053. Methods: This research is a descriptive sectional study. During the investigation, one step sampling with the necessary repetitions (if necessary) was performed of each ...

Flow in horizontally anisotropic multilayered aquifer systems with leaky wells and aquitards" (2014). [1] Flow problems in an anisotropic domain can be transformed into ones in an equivalent isotropic domain by coordinate transformations. Once analytical solutions are obtained for the equivalent isotropic domain, they can be back transformed to the original anisotropic domain. The existing solu...

Arsenic in groundwater has been a concern in South and Southeast Asia for more than a decade. We explore here the possibility that hydrogeologic factors recently shown to influence the distribution of arsenic might also affect the level of contamination of shallow (<20 m) wells with microbial pathogens. A total of 96 shallow tube wells in two nearby villages of Bangladesh were surveyed during t...

The early development of the Salton Sea geothermal resource proved that carbon steel tubulars do not provide satisfactory service life in the high-temperature, hypersaline brines. A large-scale corrosion test was designed to find the most cost-effective alloys for completing these wells. A series of Ni-Cr-Mo alloys were tested over several years in three production wells and two injection wells...

Corrosion and scaling in drinking water sources can lead to economic and health damages. These processes produce by-products in distribution systems, reduce chemical water quality, and are the cause of health issues among consumers. The aim of this study was to evaluate the corrosion and scaling potential of water supply sources of Marivan villages, Iran. In total, 106 water samples were collec...

The SlipChip is a microfluidic device designed to perform multiplexed microfluidic reactions without pumps or valves. The device has two plates in close contact. The bottom plate contains wells preloaded with many reagents; in this paper plates with 48 reagents were used. These wells are covered by the top plate that acts as a lid for the wells with reagents. The device also has a fluidic path,...
