To study the allometric growth of body and carcass traits, twelve new born Karadi lambs were docked within 3 days their birth using rubber-rings, left with mothers till weaning (2.5 months). Another 12 weaned obtained from local market intact. Following an adaptation period a week, intact average initial weight 16.83±1.522 19.92± 0.748kg, respectively randomly divided into three equal groups to...

This paper presents a geometric approach to multi-robots group formation with connectivity preservation (from a graph-theoretic perspective) among group members. The controller demonstrates consistency among different formations, as well as stability while performing dynamic switching between formations. Inter-robots collision avoidance is delivered through formation preservation, while permitt...

Deformations that conserve the parallelism and the distances –between layers, in smectic phases; between columns, in columnar phases– are commonplace in liquid crystals. The resulting deformed textures have the same mass density as in the ground state (an expected property in a liquid) and are at the same time isogonic and isometric, which imposes specific geometric features. The corresponding ...

If a visitor from Mars desired to leam the geometry of the triangle but could stay in the earth' s relatively dense atmosphere only long enough for a single lesson, earthling mathematicians would, no doubt, be hard-pressed to meet this request. In this paper, we believe that we have an optimum solution to the problem. The Kiepert conics, though seemingly unknown today, constitute a significant ...

puccinia recondite (leaf rust) is an endemic disease in iran; this disease can affect the productivity and quality of wheat, that occurring in all wheat growing regions. genetic resistance to leaf rust of wheat is the most important strategy to control the diseases and 51 leaf rust resistance genes (lr gene) are reported in wheat to provide resistance to leaf rust. this study aims to identify p...
