Several fissiparous strains of the planarian Dugesia gonocephala s.l. have been subjected for many months to continuous feeding on crushed tissues of sexually mature specimens of the planarians Polycelis nigra or (in a few cases) Dugesia lugubris. In a very high percentage of cases (especially after feeding on Polycelis nigra crushed tissues) the fissioning phenomena have been stopped and a sex...

In this paper, we discuss the applicat[ons ant! implications of the Programmable Brick-s-s tiny, portable computer embecfded ~nside a LE~Q'J brick, capable of interacting with the phys!cal world in a large variety of ways. We describe how Programmable Bricks make possible a wide range of new design activities for children, and we discuss experiences in using Programmable Bricks in three types o...

During a medical entomology course in Boa Vista, Roraima, colonies of Triatoma maculata closely associated with pigeon nests were observed in concrete air-conditioner box located on the external plastered and cemented walls of a modern brick-built apartment block. In only one eight-hole ceramic brick, located inside one air-conditioner box, 127 specimens of T. maculata were collected. T. macula...

As in the case of two-dimensional topology design optimization, numerical instability problems similar to the formation of two-dimensional checkerboard patterns occur if the standard eight-node conforming brick element is used. Motivated by the recent success of the two-dimensional non-conforming elements in completely eliminating checkerboard patterns, we aim at investigating the performance o...

Balancing business strategy and operations between electronic commerce and brick and mortar channels (‘clicks and mortar’) is an ongoing challenge for many businesses. A group of traditional ‘brick and mortar’ firms were examined in order to understand how they balance strategy and operations between electronic commerce and traditional (brick and mortar) business channels. Results of the study ...

Dissections of polytopes are a well-studied subject by geometers as well as recreational mathematicians. A recent application in coding theory arises from the problem of parameterizing binary vectors of constant Hamming weight [TVS09], [SV09], which is shown to be equivalent to the problem of dissecting a tetrahedron to a brick. An application of dissections to a problem related to the construc...

Abstract Ecological restoration aims at supporting biodiversity and ecosystem services, urban greening is a great opportunity to achieve this goal. This facilitated by species-rich seed mixtures based on local provenances, which are designed for certain nutrient moisture regimes functional plant traits. Such grassland might be cultivated crushed waste bricks, would new component of water-holdin...

The Multi-Chip-Module-Deposited (MCM-D) technique has been used to build hybrid pixel detector assemblies. This paper summarises the results of an analysis of data obtained in a test beam campaign at CERN. Here, single chip hybrids made of ATLAS pixel prototype read–out electronics and special sensor tiles were used. They were prepared by the Fraunhofer Institut für Zuverlässigkeit und Mikroint...
