In this paper five new ideas are proposed to integrate both an active RFID tag with a non-floating type thermal convection angular accelerometers on a flexible substrate, thus the device becomes a wireless sensor. The most innovative idea is to make it directly on the substrate without creating the grooved chamber of a traditional thermal convection accelerometer, and the device doesn’t use any...

Inhalation of concentrations greater than 30% of carbon dioxide (CO2) by volume in atmospheric air causes aversion in pigs. The objective of this study was to assess, using aversion learning techniques and behavioural studies, the aversion to three alternative gas mixtures of nitrogen (N2) and CO2: 70% N2 and 30% CO2 (70N30C), 80% N2 and 20% CO2 (80N20C) and 85% N2 and 15% CO2 (85N15C). The exp...

This paper is addressed to the TOUGH2 user community. It presents a new tool for handling simulations run with the TOUGH2 code with specific application to CO2 geological storage. This tool is composed of separate FORTRAN subroutines (or modules) that can be run independently using input and output files in ASCII format for TOUGH2. These modules have been developed specifically for modeling of ...

in this study, a novel solid dendrimer amine (hyperbranched polymers) was prepared using mesoporous carbon nitride functionalized by melamine based dendrimer amines. this adsorbent was denoted mda-mcn-1. the process was stepwise synthesis and hard-templating method using mesoporous silica sba-15 as a template. cyanuric chloride and n,n-diisopropylethylamine (dipea, merck) were used for function...

OBJECTIVES Venovenous extracorporeal gas exchange is increasingly used in awake, spontaneously breathing patients as a bridge to lung transplantation. Limited data are available on a similar use of extracorporeal gas exchange in patients with acute respiratory distress syndrome. The aim of this study was to investigate the use of extracorporeal gas exchange in awake, spontaneously breathing she...

Air pollution has significant influence on the concentration of constituents in the atmosphere leading to effects like global warming and acid rains. To avoid such adverse imbalances in the nature, an air pollution monitoring system is utmost important. This paper attempts to develop an effective solution for pollution monitoring using wireless sensor networks (WSN) on a real time basis namely ...

In this work, a mathematical model is established to describe the removal of CO2 from gaseous mixtures including CH4 and CO2 in a polypropylene hollow fiber membrane contactor in the presence of conventional absorbents such as monoethanolamine (MEA), methyldiethanolamine (MDEA), and a blend of them. Modeling was performed in axial and radial directions under the fully-wet condition for counterc...

We report on a novel, cost-effective non-dispersive infrared (NDIR) multi-gas sensor aimed at environmental air pollution monitoring. The rugged design of the K96 core combines highest compactness and low-power consumption with our unique multi-channel cell design, featuring detection up to three different gases simultaneously, including CO2, CH4, N2O, H2O. Our sensing platform allows selection...

The systematic and quantitative approach on the environmental pollution is a significant challenge in highly regulated industries, such as power plants, where a large amount of waste gas including greenhouse gas must be discharged. We simulated various CO2 reduction processes and estimated the total cost of those. In this study, an environmental pollution impact is analyzed by the process opera...

Li ion conducting Li3PO4 thin film electrolytes with thickness 300nm, 650nm and 1.2μm were deposited on Al2O3 substrate at room temperature by thermal evaporation method. Reference and sensing electrodes were printed on Au interfaces by conventional screen printing technique. The overall dimension of the sensor was 3 x 3 mm and of electrodes were 1 x 1.5 mm each. The fabricated solid state pote...
