STUDYING THE ELEMENTS OF THE RUSSIAN NATIONAL CULTURE AT TECHNOLOGY LESSONS

The analysis of the technology at school program is carried out in the research. Studying the national culture plays an important role on technology lessons. It is possible to study people’s life features in a deeper way. Also it is possible to feel belonging to the culture. The methodical recommendations of the training organization with the elements of national culture at technology classes are in 5 and 8 classes.

The toy-model of the Boltzmann type equation for the contact force distribution in disordered packings of particles

The packing of hard-core particles in contact with their neighbors is considered as the simplest model of disordered particulate media. We formulate the statically determinate problem which allows analytical investigation of the statistical distribution of contact force magnitude. The toy-model of the Boltzmann type equation for the probability of contact force distribution is formulated and studied. An experimentally observed exponential distribution is derived.Comment: 5 page

Sensory Ecology in Soil Space

Knowing where you are helps getting you to where you need to be. Consider being dumped into an environment of which you had no prior knowledge. Add to this the fact that you are blind, and react to surfaces, electrical fields, gas concentrations and temperature. You also know what is up and what is down, so you are aware of gravity, which is good as you are spending your life underground. Also, most of the time you need to move in water, and your life cycle is at best a couple of days at optimum temperature, and the temperature is rarely optimal. Now, find your way to a food source and avoid obstacles and predators. What strategy would you adopt to keep yourself alive and functional? This scenario roughly summarizes the challenges facing archaea, bacteria, protozoa, nematodes and, to a lesser extent, fungi in soil systems. These organisms control to a great extent our ability to utilize the Earth as a resource: growing food, clean water, etc. These organisms reside and are active in a dark, dank, complex physical environment that exhibits extreme changes in moisture, temperature and architecture over very short spatial and temporal scales. Thus, they have evolved perhaps unrivalled abilities to adapt rapidly to constantly changing environmental conditions. Alexander et al. (2006), in a summary of energy taxis in microorganisms, highlight the fact that genome sequencing of marine and soil microbes has shown that they possess large numbers of chemoreceptors, whereas microbes in environments that experience relatively constant environmental conditions are more likely to have significantly fewer chemoreceptors. The question is: How do they sense and respond to these conditions in soil

CELNETANALYZER: HIGH-PERFORMANCE JAVA PACKAGE FOR THE TOPOLOGICAL ANALYSIS OF CELLULAR NETWORKS

Summary: A simple-to-use Java-based software package CelNetAnalyzer was developed. CelNetAnalyzer is managed through a graphical user interface and it returns a comprehensive list of the topological indices including compositional complexity, degree and neighbourhood, clustering, distance, centrality and heterogeneity indices as well as simple cycles and Shannon information entropy of undirected networks. Comparative studies have shown that due to parallelization and use of enhanced and newly developed algorithms, CelNetAnalyzer calculates these parameters significantly faster than competitors. Availability and Implementation: CelNetAnalyzer is an open-source project and free distributed for non-commercial use. Software package, source code, test network and the results of the topological analysis can be downloaded from website of the Department of Genetics at Belarusian State University (http://bio.bsu.by/genetics/grinev_software.html).
