Introduction. The mechanism of the formation snow deposits on shell Luzhniki GSA and their redistribution in winter were established basis data obtained during monitoring load for over 20 years. Aim. In this article, distribution determined, along with numerical values form factor μ characterizing transition from ground to shell. Materials methods. measurements density carried out 1998 2019. re...

We consider a competitive facility location problem with two players. Players alternate placing points, one at a time, into the playing arena, until each of them has placed n points. The arena is then subdivided according to the nearest-neighbor rule, and the player whose points control the larger area wins. We present a winning strategy for the second player, where the arena is a circle or a l...

Poetry is a means of conveying ideas. Wiji Thukul poet who was allegedly lost because his poetry. This study describes the textual strategy or writing poetry that took in symbolic contestation Indonesian literary arena during New Order era. research uses Pierre Bourdieu's cultural production theory to describe and explain Thukul's problems, both intrinsic extrinsic, simultaneously. The data sou...

The active place avoidance task is a dry-arena task used to assess spatial navigation and memory in rodents. In this task, a subject is put on a rotating circular arena and avoids an invisible sector that is stable in relation to the room. Rotation of the arena means that the subject's avoidance must be active, otherwise the subject will be moved in the to-be-avoided sector by the rotation of t...

In a mutualistic relation between a potter wasp, Allodynerus delphinalis (Giraud) (Hymenoptera: Vespidae), and its specific parasitic mite, Ensliniella parasiticaVitzthum (Winterschmidtiidae), behaviour of the mite guarding the wasp and attacking their common natural enemy, Melittobia acasta (Walker) (Hymenoptera: Eulophidae), was examined. While mite attacks to M. acasta occurred by accidental...

The hippocampal formation is known to be critical for spatial cognition, for example, regulating the learning of environmental maps. But how is a spatial map learned, and what is the role of the hippocampal formation in the learning process? The sun compass is perhaps the most ubiquitous, naturally occurring spatial orientation mechanism found in the animal kingdom. The sun compass may also ser...

The spontaneous firing activity of the place cells reflects the position of an experimental animal in its arena. The firing rate is high inside a part of the arena, called the firing field, and low outside. It is generally accepted concept that this is the way in which the hippocampus stores a map of the environment. This well known fact was recently reinvestigated [Fenton, A.A., Muller, R.U., ...

Many invading species have brought devastating parasites and diseases to their new homes, thereby imperiling native taxa. Potentially, though, invaders might have the opposite effect. If they take up parasites that otherwise would infect native taxa, but those parasites fail to develop in the invader, the introduced species might reduce parasite burdens of the native fauna. Similarly, earlier e...

Abstract Simulation software enables to build and process FMS models to analyse different aspects of the system operation. Such models, verified in simulation experiments, are ready to be used for FMS control to calculate control decisions. The idea of using simulation software Arena to control FMS is presented in the paper. Basic characteristic of modelling and simulation in Arena is presented...
