The actual global financial crisis puts a lot of challenges for the monetary policy that should remains consistent, credible and effective. In the crisis period, the monetary policy strategy was based on the following aspects. First, it was important to maintain the price stability. The response of the monetary policy during the financial crisis was focused on supporting banks in the fulfillment of their major role to provide credit to the real economy. All these measures have been fully consistent with the major objective of ensuring price stability. The exit from these special measures is gradually. The role of asset prices in the conduct of modern monetary policy in turbulent periods was proved again as very important both for recovery after crisis and also to prevent another future financial crisis. Regarding the monetary policy, after this global crisis there are several lessons learn from the causes and the risk management in turbulent periods. The central banks should have a more clear strategy and a better framework for communication. Monetary policy strategy should allow the risks to price stability considering also the imbalances in both domestic and global markets mixed with the new role of asset prices in monetary policy management.

In this paper we studied a device based on array of six different sensors with surface acoustic wave for detections and recognition of three chemical warfare agents (Chloropicrin, Soman and Lewisite). The sensors are "delay line" type with a center frequency of 69.4 MHz. It presents an original algorithm to identify the nature and concentration of gas from a finite range of possible gases. Numerical program developed to implement this algorithm, provides to operators all the particulars of gas and an indicator of credibility of the results provided as a measure of the degree of disturbance of the signals received from sensors. © 2010 IEEE.

The comparative study of surface acoustic wave sensors (SAWS) coated with sensitive layer of polymer and nanoparticles embedded in polymer was made. The sensors were designed for chemical warfare agent detection. SiO2, TiN, TiO2 and Co3N nanoparticles embedded in polyethylenimine (PEI) were used as sensitive material. The sensors were "delay line" type with a center frequency of 69.4 MHz, fabricated on ST cut quartz substrate. The sensitivity and limit of detection was reported for three chemical agents: chloropicrin (CCl3NO2), lewisite (C2H2AsCl3) and soman (C7H 15FPO2). The study demonstrated that in comparison with plain polymer sensitive layer, the sensor with nanocomposite had an improved limit of detection, in some case three times better. Source

This paper presents a portable device for rapid preparation of samples, in situ, in order to facilitate the detection and identification of toxic substances. This product is for research and provides increased sensitivity NBC detection equipment (ion mobility spectrometers, indicated tubes), and decreasing the time needed for preparation solid and liquid samples to identify toxic substances by spectrometric techniques (gas chromatography with mass spectrometry). It is used especially for preparing various types of samples (soil, water, organic solvents), in situ, in diverse climate conditions. This device permits the decreasing of the detection and identification time of the toxic substances in chemical incidents, influencing in a positive way the period of the specific laboratory operations by performing them on site. It can be used for military and civil institutions that hold equipment for detection and identification or by policy makers who must intervene in chemical incidents (military conflicts, accidents or terrorist actions).
