Analysis of light optical diffraction patterns produced by electron micrographs can easily lead to much nonsense. Such diffraction patterns are referred to as optical transforms and are compared with transforms produced by a variety of mathematical manipulations. In the use of light optical diffraction patterns to study periodicities in macromolecular ultrastructures, a number of potential pitfalls have been rediscovered. The limitations apply to the formation of the electron micrograph as well as its analysis.(1) The high resolution electron micrograph is itself a complex diffraction pattern resulting from the specimen, its stain, and its supporting substrate. Cowley and Moodie (Proc. Phys. Soc. B, LXX 497, 1957) demonstrated changing image patterns with changes in focus. Similar defocus images have been subjected to further light optical diffraction analysis.

Anti Virus are nasty software’s. It is designed to damage computer systems without the knowledge of the owner using the system and technique advancements are posing big challenges for researchers in both academia and the industry. The purpose of this study is to examine the available literatures on Anti Virus analysis and to determine how research has evolved and advanced in terms of quantity, content and publication outlets. Most Anti Virus programs are large and complex and one can’t possibly understand every detail. Educating the internet users about Anti Virus attack, as well as the implementation and proper application of anti-Anti Virus tools, are critical steps in protecting the identities of online consumers against Anti Virus attacks.


In an era of mass mobility, those who are permitted to migrate and those who are criminalized, controlled, and prohibited from migrating are heavily patterned by race. By placing race at the centre of its analysis, this volume brings together fourteen essays that examine, question, and explain the growing intersection between criminal justice and migration control. Through the lens of race, we see how criminal justice and migration enmesh in order to exclude, stop, and excise racialized citizens and non-citizens from societies across the world within, beyond, and along borders. Neatly organized in four parts, the book begins with chapters that present a conceptual analysis of race, borders, and social control, moving to the institutions that make up and shape the criminal justice and migration complex. The remaining chapters are convened around the key sites where criminal justice and migration control intersect: policing, courts, and punishment. Together the volume presents a critical and timely analysis of how race shapes and complicates mobility and how racism is enabled and reanimated when criminal justice and migration control coalesce. Race and the meaning of race in relation to citizenship and belonging are excavated throughout the chapters presented in the book, thereby transforming the way we think about migration.

AbstractThe article deals with the research of operational reliability of forest felling machines by FMEA method (Failure Mode and Effect Analysis). It describes collection of operational data and its analysis. It explains the procedure of realization for the method FMEA in the organization. Harvesters John Deere 1070D in the Company Lesy SR B. Bystrica were chosen for this research. The research was held in real operational conditions. Application of the FMEA method allows flexibility in case of unexpected situations and optimization of human potential abilities. FMEA tool is a tool preventing outages operational reliability and preventive tool for ensuring the maintenance of facilities. The method of information analysis mentioned below is simple ale precise enough for implementation in real working conditions.
