In the centrosymmetric title binuclear complex, [Zn(2)(C(8)H(7)O(2))(4)(C(7)H(10)N(2))(2)], the Zn atoms [Zn⋯Zn = 3.0287 (6) Å] are bridged by four 4-methyl-benzoate ligands. The four nearest O atoms around each Zn(II) atom form a distorted square-planar arrangement with the distorted square-pyramidal coordination completed by the pyridine N atom of the 4-(dimethyl-amino)pyridine ligand. In the...

This study aims to describe students' mathematical communication skills in the climber category. Subjects this were selected based on results of ARP test. The techniques used tests and interviews with students who from class VII junior high school students. For data analysis, Miles Huberman method was used. are able fulfill all established indicators. Climber express real objects, situations ev...

Hyperventilation is one of the most important features of acclimatization to high altitude. Resting ventilation at extreme altitudes increases up to fourfold and exercise ventilation for a given work level increases to the same extent. Hypoxic stimulation of the peripheral chemoreceptors is the chief mechanism for the hyperventilation but there is also evidence that central sensitization of the...

We present a hybrid metaheuristic approach for the machine reassignment problem, which was proposed for ROADEF/EURO Challenge 2012. The problem is a combinatorial optimization problem, which can be viewed as a highly constrained version of the multidimensional bin packing problem. Our algorithm, which took the third place in the challenge, consists of two components: a fast greedy hill climber ...

UNLABELLED Closed rupture of the flexor tendon sheath has been known to occur in the elite rock climbing population. However, only one study has investigated the prevalence of this entity. PURPOSE To examine an elite climbing group in this country for the prevalence of pulley rupture and report on other commonly occurring injuries in the hand and elbow. METHODS 42 elite rock climbers compet...

One way to solve problems in mathematics is think algebraically. Algebraic thinking using generalization abilities, transformational and global meta-level abilities problems. A person's ability overcome called Adversity Quotient (AQ). There are three categories (AQ): climber, camper, a quitter. This study aimed describe the profile of students' algebraic solving mathematical terms Quotient. res...
