The asymmetric unit of the title Cd(II) coordination polymer, [Cd(2)(C(8)H(6)O(8))(H(2)O)(3)](n), contains two crystallographically independent Cd(II) cations, one-half each of two independent anionic butane-1,2,3,4-tetra-carboxyl-ate units (L) and three water mol-ecules. Both anionic units lie on inversion centers. One of the Cd(II) ions is six-coordinated by four carboxyl-ate O atoms from fou...

New methods for the preparation of reversible pH-responsive DNA hydrogels based on Hoogsteen triplex structures are described. One system consists of a hydrogel composed of duplex DNA units that bridge acrylamide chains at pH = 7.4 and undergoes dissolution at pH = 5.0 through the reconfiguration of one of the duplex bridging units into a protonated CG·C+ triplex structure. The second system co...

New methods for the preparation of reversible pH-responsive DNA hydrogels based on Hoogsteen triplex structures are described. One system consists of a hydrogel composed of duplex DNA units that bridge acrylamide chains at pH 1⁄4 7.4 and undergoes dissolution at pH 1⁄4 5.0 through the reconfiguration of one of the duplex bridging units into a protonated CG$C triplex structure. The second system...

In this paper, a reinforced concrete(RC) bridge built in an interchange, in the city of Kerman (a city located in south of Iran) is examined by the Structural Health Monitoring (SHM) system. During the construction of this bridge such as; the main beams, slab, and retaining walls, some Electrical Strain Gauges were mounted on the main reinforcements at different locations within the body of thi...

BACKGROUND Nowadays, molecular techniques are widespread tools for the identification of biological entities. However, until very few years ago, their application to taxonomy provoked intense debates between traditional and molecular taxonomists. To prevent every kind of disagreement, it is essential to standardize taxonomic definitions. Along these lines, we introduced the concept of Integrate...

in this paper, a new cascaded multilevel inverter by capability of increasing the number of output voltage levels with reduced number of power switches is proposed. the proposed topology consists of series connection of a number of proposed basic multilevel units. in order to generate all voltage levels at the output, five different algorithms are proposed to determine the magnitude of dc volta...

In this study, a system for monitoring the structural health of bridge deck and predicting various possible damages to this section was designed based on measuring the temperature and humidity with the use of wireless sensor networks, and then it was implemented and investigated. A scaled model of a conventional medium sized bridge (length of 50 meters, height of 10 meters, and with 2 piers) wa...

This paper presents results of comprehensive analyses of data from the first 122 commercially available wireless environmental pervasive sensors (motes), developed by Newcastle University and deployed in England. Measurements of pollution, meteorology and traffic are used to investigate the complexity of the physical and chemical processes governing the levels of traffic-related pollution in ur...
