Research has not explored the extent to which seeking help from teammates positively relates to a person's own creativity. This question is important to explore as help seeking is commonly enacted in organizations and may come with reciprocation costs that may also diminish creativity. Results based on 291 employees in a single division of a large multinational organization revealed that seekin...

The present work aims to predict drug release from novel site-specific release isoniazid pellets, in USP dissolution test apparatus 3, using the response surface methodology (RSM). Site-specific release isoniazid pellets were prepared by extrusion-spheronization followed by aqueous coating of Acryl-EZE. RSM was employed for designing of the experiment, generation of mathematical models and opti...

One conspicuous feature of several larger bird species is their annual migration in V-shaped or echelon formation. When birds are flying in these formations, energy savings can be achieved by using the aerodynamic up-wash produced by the preceding bird. As the leading bird in a formation cannot profit from this up-wash, a social dilemma arises around the question of who is going to fly in front...

In 7 patients, none of whom had the WPW syndrome, analysis of recurrent paroxysms of supraventricular tachycardia strongly favoured the existence of re-entry in the AV junction as the underlying mechanisms. Paroxysms were abortive in 4 patients and sustained in the remaining 3. The initiating factors were partial AV block and/or premature beats or premature depolarization from re-entrant impuls...

background: the aim of this study was to evaluate apical transportation and centering ability of single-fi le instruments, waveone primary, with full rotation versus reciprocation movement using cone-beam computed tomography (cbct) analysis in curved mesiobuccal (mb) root canal of human mandibular molars. materials and methods: thirty mb canals of mandibular molars were randomly divided into tw...

Some parts of the material in this paper were presented by the author in the meeting Combinatorics 2008 celebrated at Costermano, Italy the last June. So it contains some expository on previous work but it also contains new and original results, mainly those in the last two sections. The results in this paper are consequences of a special interpretation as fixed point problems of the two classi...

Grooming is one of the most conspicuous social interactions among nonhuman primates. The selection of grooming partners can provide important clues about factors relevant for the distribution of grooming within a social group. We analyzed grooming behavior among 17 semi-free ranging female Barbary macaques (Macaca sylvanus). We tested whether grooming is related to kinship, rank and friendship....
