Automatic steering systems have been available for several years. Mechanical feeler systems, including the Tri-R system2, can provide moderate performance at a reasonable cost, but face limitations (Figure 1). Mechanical feel systems are crop limited and require a relatively stiff crop that has reached sufficient maturity for the feeler to detect. The feeler systems are both speed and curve lim...

BACKGROUND The radial approach has been increasingly used as an alternative to femoral access. And more procedures using repeated transradial coronary intervention (r-TRI) are performed. However, few data about r-TRI has been obtained. Therefore, we investigated the safety and feasibility of r-TRI using the same route. METHODS A total of 423 consecutive eligible patients undergoing r-TRI were...

The asymmetric unit of the title compound, (C(7)H(18)N(2)O)(2)[Cd(2)Cl(8)], comprises one 4-(2-hy-droxy-eth-yl)-2-methyl-piperazine-1,4-diium dication and a half [Cd(2)Cl(8)](4-) anion. The two Cd atoms are each coordinated by two bridging Cl atoms and three terminal Cl atoms and the [Cd(2)Cl(8)](4-) anion is located on an inversion centre. The crystal structure consists of N-H⋯Cl hydrogen-bond...

Extensive bibliography on isomerism of cyanuric acid is presented. Nine possible isomers of cyanuric acid are characterized computationally. The tri-oxo tautomer is by far the most stable isomer of cyanuric acid. The tri-hydroxy form is by more than 100 kJ mol 1 higher in energy than tri-oxo. Cyanuric acid under all experimental conditions exists as tri-oxo tautomer. g r a p h i c a l a b s t r...

this study was performed to compare the biomar nutritional diet, shrimp, bloodworms on growth parameters, survival and blood parameter of juvenile aquarium joel (hemichromis bimaculatus). the experiment treatments consisted of blood worms, dried shrimp and control treatment that were biomar food. daily feeding was performed 4 times in a day to satiation and breeding fish took place over 8 weeks...
