Sensing system to monitor natural disasters faces much hard conditions. Natural disaster occurs suddenly, and damages sensor system. Then, the sensor system should be designed as distributed node network. In addition to that, the network should have some characteristic functions like self-recovery, autonomous operation and effective data transmission in urgent. This paper describes the construction of autonomous sensing node network to recover the damage by landslide disaster and to transmit urgent data effectively. By switching operation modes autonomously, the sensing node network becomes robust system to the loss/insert of sensing node and the dynamic control of data transmission.

In this work the Proficiency Testing Scheme (PTScheme) had been used for evaluation of performance of the laboratories of automotive emissions to measure the levels of emissions of the vehicles, supplying subsidies to the laboratories in order to identify and solve analytical problems and contributing for the harmonization of the results of the measurements in the country. The PTScheme of automotive emissions is a type of study, provided only in Brazil and it can be concluded that the results have been satisfactory and of great importance for the industry, society and environment. In this work is presented a comparison of results for the four rounds held covering the period from 2004 to 2010.

This paper is relating the effort to organize a pertinent measurement plan to analyze 2 aquatic ecosystems, a canal and a lake, where the issue is to improve the natural surviving of fishes for the benefit of local angling clubs.
The first case is a 4 century old canal, located in a castle, built from its very beginning for French king entertainment and trout rising; the issue is related to the massive introduction of new fishes every November which are disappearing during winter while trout, fishes very sensitive to pollutions, are surviving.
The second case is a more recent lake dedicated to fly fishing, where the issue is quite the opposite: introduction of trout is resulting, after a month, into a complete disappearance of these fishes while other alien species are still alive with a good reproduction rate. In both case there is no trace of dead bodies or other visual evidences of the changes.
The measurement plan is considering over 1000 different parameters that may explain the lethal for life situation of aquatic ecosystems and is creating a typology and hierarchy of these parameters to build a measurement sequence. A set of abiotic specifications was created with a scale compared to Nisbet & Verneaux abiotic inventory of French lakes and rivers.
The paper will cover the different techniques used for that purpose and what we have learned to obtain reliable results for physical measurements (flow, laminar flow, volume and water renewal rate, temperature etc¡K), abiotic (pH, redox, conductivity, hardness, dissolved gas etc¡K), biotic index, and comparison to biological history (sclerochronology ).
The presentation will show several tools we have developed for mass sampling, continuous surveillance and GPS driven measurements.
The conclusion will show the need for a systemic approach to integrate all these measurements into a consistent model for overall behavior and productivity prediction.

The paper is devoted to the abilities of Raman probe to detect simultaneously several salts diluted in water. It has shown that this probe can be used for in situ monitoring of pollutants in waste water.

This paper addresses the measurement framework underlying experimental works on time discounting and the methodological reasons of the high variability of its empirical results. In particular, the paper discusses the argument that the variability of the results is due to the context-dependency of the processes that motivate people to display discounting behavior.
