We consider an ideal gas of infinitely rigid rods near a perfectly repulsive wall, and show that the interfacial tension of a surface with rods on one side is lower when the surface bends towards the rods. Surprisingly we find that rods on both sides of surfaces also lower the energy when the surface bends. We compute the partition functions of rods confined to spherical and cylindrical open sh...

We present the i-ConeTM: a new projection-based panoramic display system for virtual environments. The i-ConeTM uses conical screen geometry, resulting in optimized projector placement to create an extended workspace for standing participants in a front projection curved screen display with a very large continuous field of view. Improved acoustical properties of the conical screen geometry enab...

The theme of this paper is interaction between and within plate-based roof structures braced by branching columns and tensile members. Interaction of cross-laminated timber plate structures and branching column systems have been investigated in a previous paper [1] by utilising physical models and Genetic Algorithms. Based on this study the concept of interaction and the utilisation of compress...

Widow remarriage practices in the Punjab-Haryana region of northern India are described as frequently mismatched and undesirable alliances, without widow choice, which serve to support the practice of polygamy. The average spacing between arranged spouses could be 10 years, with the younger spouse being the brother-in-law (this customary practice of remarriage within the husbands' family is ca...

A new species attributed to the genus Parvifuzia Guo & Ren, 2011, Parvifuzia peregrinasp. n., is described from the Middle Jurassic Jiulongshan Formation of Daohugou Village, Inner Mongolia, China. This new species, with apex of wing almost reaching the end of the abdomen and forewing venation with 30-32 veins at margin, broadens the diversity of Parvifuzia. This new species, with strongly curv...

introduction: the purpose of this in vitro study was to compare the accuracy of the new electronic apex locator raypex5 with radiography for working length determination of straight and curved root canals. materials and methods: twenty straight and single canals of maxillary central teeth and twenty curved mesiobuccal canals of mandibular molar teeth were used. access cavities were prepared and...

Hydroporus sejilashan sp. n. is described from Xizang Autonomous Region (Qinghai-Tibet Plateau), China. It belongs to the acutangulus-complex of the Hydroporus planus-group and can be separated from all four other members of the species complex by the completely distinctly matt surface in both sexes. In addition it can be distinguished from Hydroporus acutangulus Thomson, 1856 and H. polaris Fa...
