In order to describe iron stability in plastic pipes and to ensure the drinking water security, the influence factors and rules for iron adsorption and release were studied, dependent on the Unplasticized poly (vinyl chloride) (PVC-U) drinking pipes employed in this research. In this paper, sulfate, chloride, and bicarbonate, as well as synthesized models, were chosen to investigate the iron st...

BACKGROUND In 2011, a multidisciplinary team investigated two diarrhoea outbreaks affecting urban Bangladeshi communities from the districts of Bogra and Kishorganj to identify etiology, pathways of transmission, and factors contributing to these outbreaks. METHODS We defined case-patients with severe diarrhoea as residents from affected communities admitted with ≥3 loose stools per day. We l...

This paper presents the SONIC reconfigurable computing architecture and the first implementation, SONIC-1. SONIC is designed to support the software plug-in methodology to accelerate video image processing applications. SONIC differs from other architectures through the use of Plug-In Processing Elements (PIPEs) and the Application Programmer’s Interface (API). Each PIPE contains a reconfigurab...

Rocks and fossils do not come with labels informing us of their age. They must be understood in light of their geologic context, and interpreted within a worldview. Unfortunately, my evolutionary colleagues are often so dominated by uniformitarian brainwashing they can't objectively understand young-Earth evidence. Nevertheless, some of the evidence is clear and open for all to see. One such cl...

This paper presents a feasibility study to improve thermal loading of existing radioactive material packages by using heat pipes. The concept could be used to channel heat in certain directions and dissipate to the environment. The concept is applied to a drum type package because the drum type packages are stored and transported in an upright position. This orientation is suitable for heat pip...

Green buildings are increasingly being plumbed with crosslinked polyethylene (PEX) potable water pipe. Tap water quality was investigated at a six month old plumbing system and chemical and odor quality impacts of six PEX pipe brands were examined. Eleven PEX related contaminants were found in the plumbing system; one regulated (toluene) and several unregulated: Antioxidant degradation products...

Architecture–based reliability analysis is necessary for a software application that is developed using the component–based software development paradigm. Prevalent architecture–based analysis techniques represent the application architecture by a Markov process, which may be adequate in the context of an application with a general– purpose architecture. The Markov process, however, is not adeq...

The purpose of this research is to realize a small robot which can negotiate pipes whose diameter varies widely during the robot’s course. A new in-pipe locomotion mechanism named “snaking drive” is proposed in this paper and its potential and fundamental characteristics are shown with experimental data of the prototype model. First, in the sections 2 to 5, the basic traveling characteristics o...

Unix-based operating systems feature several forms of Inter-Process Communication (IPC) including pipes, Unix domain sockets, TCP/IP sockets, FIFOs, semaphores, and signals. Although these mechanisms provide similar services, each is designed differently with varying levels of performance. To better understand how these mechanisms work and why they perform the way they do, their implementations...
