Abstract: Mine ventilation system is critical for maintaining safe working conditions in an underground coal mine. At present, there exist some problems in developing mine ventilation software such as long development cycle, redevelopment, low commercialization and weak extensibility. The traditional digital mine ventilation systems is complicated to be modified or extended after published unle...

We report a novel system to analyze atmospheric nitrophenols (NPs). Rain or air sample extracts (1 mL) are preconcentrated on a narrow bore (2 mm) aliphatic anion exchanger. In the absence of strong retention of NPs exhibited by aromatic ion exchangers, retained NPs are eluted as a plug by injection of 100 microL of 0.1 M Na(2)SO(4) on to a short (2 x 50 mm) reverse phase C-18 column packed wit...

The ability to amplify genomic DNA in a polymerase chain reaction (PCR) is dependent upon the purity of the DNA template. Environmental genomic DNA often contains contaminants (e.g., polyphenols, humic acids, polysaccharides) that reduce template purity and can be difficult to remove, thereby inhibiting PCR amplification. There is thus a need for a method to purify extracted genomic DNA without...

Coronary artery disease remains a common problem in industrialized countries. Percutaneous coronary interventions are usually performed utilizing the femoral approach. Arterial puncture-closing devices have been developed in hope to avoid manual compression and shortening the period of rest. In a recent meta-analysis in the Journal of the American Medical Association these devices have shown on...

This pattern collection helps to define, implement and package Plug-Ins specific to an extensible application. Central patterns are the Plug-In and the Plug-In Contract between the Plug-In and the application; afterwards patterns for packaging and registration of Plug-Ins are explored. Process and organisation patterns complement the general technical patterns, and support the technical flexibi...

Integrating tools implemented as plug-ins is a complex and time-consuming activity that requires good programming skills and a deep understanding of the underlying plug-in architecture for successful completion. Even when tools are implemented as plug-ins for a same integrated development environment (IDE), users frequently prefer to manually perform the same inefficient operations every time t...

Effects of some important parameters like impactor effects, plug geometry and initiation points on bonding aluminum tubes to aluminum plugs were studied. The impact velocity and dynamic angle between tube and plug should be precisely managed to achieve an optimum bonding condition. A new explosive bonding technique with the use of two material impactors was proposed. Results are especially suit...

statement of problem: endodontic treatment of necrotic teeth with open apices is a challenge. after ruling out surgery as a treatment scheme and introduction of the multivisit apexification which in turn had its disadvantages, apical plug seems to be a suitable substitute treatment plan for such cases. apical plug makes the treatment through formation of a barrier against the obturating materia...

More and more security vulnerabilities were found in network softwares nowadays, making network security assessment one of the most important tasks for IT administrators. Vulnerability scanner is the key application for fulfilling such tasks. However, large numbers of vulnerabilities result in even larger number of vulnerability plug-ins including common plug-ins and specific plug-ins, which ma...

A numerical framework for modelling platelet plug dynamics is presented in this work. It consists of an extension of a biochemical and plug growth model with a solid mechanics model for the plug coupled with a fluid-structure interaction model for the blood flow-plug system. The platelet plug is treated as a neo-Hookean elastic solid, of which the implementation is based on an updated Lagrangia...
