The title compound, C(15)H(14)N(10), is a multidentate ligand obtained by the reaction of 5-(2-pyrid-yl)tetra-zole with 1,3-dibromo-propane. The mol-ecule consists of two 5-(2-pyrid-yl)-1H-tetra-zol-1-yl units connected by a propyl-ene bridge in a U-like conformation. A twofold rotation axis passes through the central C atom.

An anthracenyl-Bodipy dyad containing a triazole bridge, that acts to decouple the two units in the ground state, has been synthesised and structurally characterised. Efficient electronic energy transfer occurs from the anthracenyl-based unit to the Bodipy system in toluene in around 12 ps, and becomes faster in solvents of lower refractive index. The rate of electronic energy transfer is discu...

The title Schiff base compound, C(32)H(22)N(4)O, was prepared by a reaction of 4,4'-diamino-diphenyl ether and 2-quinoline-carboxaldehyde. The mol-ecule consists of two 4-{N-[(E)-quinolin-2-yl-methyl-idene]amino}-phenyl units linked by an oxygen bridge. The dihedral angles between two benzene rings and between the two quinoline ring systems are 53.81 (7) and 42.56 (4)°, respectively. Inter-mole...

Testing and validation processes are critical tasks in developing a new hardware platform based on a new technology. This paper describes a series of experiments to evaluate the performance of a newly developed MEMS-based wireless sensor node as part of a wireless sensor network (WSN). The sensor node consists of a sensor board with four accelerometers, a thermometer and filtering and digitizat...

The efficacy of intraoperative cisternal irrigation using tissue-type plasminogen activator (tPA) combined with continuous cisternal drainage was assessed for the prevention of symptomatic vasospasm in patients with aneurysmal subarachnoid hemorrhage (SAH). Seventy consecutive patients underwent direct surgery for aneurysm clipping within 48 hours of SAH and had computed tomography (CT) finding...

OBJECTIVE Despite evidence that preoperative aspirin improves outcomes in cardiac surgery, recommendations for aspirin use are inconsistent due to aspirin's anti-platelet effect and concern for bleeding. The purpose of this study was to investigate preoperative aspirin use and its effect on bleeding and transfusion in cardiac surgery. METHODS This retrospective study involved consecutive pati...

Bacterial contamination of urinary drainage bags is a frequent source of bladder bacteriuria in patients with indwelling catheters. Previous work demonstrated that the addition of 30 ml of 3% H2O2 prevented bacterial contamination of urinary drainage bags for up to 8 h in patients with urinary infections (greater than 10(5) colony-forming units per ml). Survival curves of a variety of organisms...

As a temporary means of water transportation, floating bridges play an important role in the military and other fields. However, traditional have limitations such as large size, heavy weight, slow construction time. In this paper, we propose rigid-flexible composite folding bridge. The main structure bridge consists three layers: deck, airbag, bag. units are connected by flexible connectors to ...

The excited-state dynamics of two energy donor-bridge-acceptor (D-B-A) systems consisting of a zinc tetraphenylporphyrin (ZnP) and a free base tetraphenylporphyrin (FbP) bridged by oligo-p-phenyleneethynylene units with different substituents has been investigated using ultrafast spectroscopy. These systems differ by the location of the lowest singlet excited state of the bridge, just above or ...
