Dogs have the ability to determine the direction of an odour trail left by a human. This study examined how much olfactory information from this trail is required by dogs to determine direction. Six dogs, able to determine direction, were tested on a 21 footstep trail laid on 21 individual carpet squares, one footstep per square, by the same individual wearing the same shoes. Dogs brought in at...

Erdős space E is the ‘rational’ Hilbert space, that is the set of vectors in ` the coordinates of which are all rational. Erdős proved that E is one-dimensional and homeomorphic to its own square E × E, which makes it an important example in dimension theory. Dijkstra and van Mill found topological characterizations of E. Let M n , n ∈ N, be the n-dimensional Menger continuum in R, also known a...

this paper examines the relation between emotional intelligenceand work-family conflict in manufacturing environment. a questionnairesurvey was carried out to explore this relation at carpet factoriesin kashan, iran. a 28-item questionnaire which consist of emotionalintelligence and work-family conflict parts was carried out to investigatethe relation between these variables. some basic socio-d...

Wool in carpets is formed by proteins, where many side chains are polar and ionisable, enabling wool to function as a polymeric ligand exchanger. This project has successfully bound either hydrated ferric oxide (HFO) nanoparticles (Figure 1) or a copper(II) salt onto waste carpet to form a sorbent material. The strongest binding was seen after first modifying the carpet by an alkaline oxidation...

Adhesion of membranes and filaments on periodic rippled surfaces is studied by means of a one-dimensional model. The adhesion behavior is found to depend crucially on the shape of the ripples. Fakir-carpet and sinusoidal patterns are studied in detail. Infinite staircases of periodic ground states are found, with a periodicity diverging at a transition line. Moreover, the boundaries of the regi...
