The asymmetric unit of the title coordination polymer, [Y(2)(C(8)H(5)NO(4))(3)(C(3)H(7)NO)(4)](n), contains one Y(3+) ion, three half-mol-ecules of the 2-amino-benzene-1,4-dicarboxyl-ate (abz) dianion and two O-bonded N,N-dimethyl-formamide (DMF) mol-ecules. Each abz half-mol-ecule is completed by crystallographic inversion symmetry and its -NH(2) group is disordered in each case [relative occu...

Photographs and transparencies of the techniques used in belaying, combined with information gained from discussions amongst experienced climbers, provided evidence of the potential injury mechanisms which may be subjected to the belayer in having to arrest a falling climber, whilst moving towards the belayer.

In the title compound, [Cu(2)(C(7)H(5)O(2))(4)(C(10)H(9)N)(2)], the paddle-wheel-type dinuclear complex is constructed by four bridging benzoate groups and two terminal 6-methyl-quinoline ligands. The asymmetric unit contains one-half of the whole mol-ecule, and there is an inversion center at the mid-point of the Cu⋯Cu bond. The octa-hedral coordination of each Cu atom, with four O atoms in th...

Caesalpinia digyna Rottl. (Caesalpiniaceae) is shrubby perennial climber found in Eastern Ghats. Roots are astringent and used in Ayurveda and Unani systems of medicines. Bergenin, Caesalpinine A and Caesalpinine C were isolated from the roots. However, this medicinal plant has not been studied pharmacognostically. Hence, the present investigation reports pharmacognostical and physicochemical p...

A dipole-loaded monopole antenna is optimized for uniform hemispherical coverage using VSO, a new global search design and optimization algorithm. The antenna's performance is compared to genetic algorithm and hill-climber optimized loaded monopoles, and VSO is tested against two suites of benchmark functions and several other algorithms.

This paper describes an integrated quasi‐ autonomous four‐limbed robot, named Capuchin, which is equipped with appropriate sensing, planning and control capabilities to “free‐climb” vertical terrain. Unlike aid climbing that takes advantage of special tools and/or engineered terrain features, free climbing only relies on friction at the contacts between the climber and the ri...
