The structure of the title compound, [Nd(2)(C(7)H(7)NO(2))(4)(H(2)O)(8)]Cl(6)·4H(2)O, consists of dimeric cationic units related by an inversion centre. The two Nd(III) atoms are linked by two bridging bidentate carboxyl-ate groups and two bidentate chelating bridging carboxyl-ate groups, with an Nd⋯Nd separation of 4.1259 (4) Å. Each Nd(III) atom is nine-coordin-ated by five O atoms from the c...

Wireless Sensor Networks; Clustering; Energy; Mission cost; Genetic algorithm Abstract In Wireless Sensor Networks (WSNs), the network’s performance is usually influenced by energy constraint. Through a well-designed clustering algorithm, WSN’s energy consumption can be decreased evidently. In this paper, an Improved Multi-Objective Weighted Clustering Algorithm (IMOWCA) is proposed using addit...

In the title compound, [Nd(NO(3))(4)(C(18)H(15)N(4)O(2))(C(18)H(14)N(4)O(2))], the Nd(III) centre is located on a twofold axis and exhibits a ten-coordinated distorted bicapped square-anti-prismatic geometry. The pyridinium NH H atom is disordered over the two ligands. Adjacent mononuclear clusters are linked through N-H⋯O and N-H⋯N hydrogen-bonding inter-actions, generating layers in the (102)...

In 1945, the Cairo Academy for the Arabic Language opened a contest to find the best project for simplification of the Arabic writing system. They received about 200 replies. We have chosen three of these projects (a preliminary project by an Academy subcommitee, and projects by Ahmed Lakhdar-Ghazal and Yahya Boutemene) and have implemented them via theΩ typesetting system. In this paper we des...

The title Nd complex [Nd(2)(C(4)H(5)O(2))(6)(H(2)O)(4)]·2C(5)H(6)N(6) is isotypic with two previously reported Dy and Ho isologues. It is composed of [Nd(crot)(3)(H(2)O)(2)](2) dimers [crot(onate) = but-2-enoate = C(4)H(5)O(2)], built up around symmetry centres and completed by 2,6-diamine-purine mol-ecules acting as solvates. The neodymium cations are coordinated by three chelating crotonato u...
