The subject of the article is the Information-Based Revolution in Military Affairs (RMA). The concept of RMA is identified as a way to increase combat capabilities based on a synergy between three spheres: information acquisition, information processing and transfer, and making use of information in order to enhance firepower. RMA includes following key elements, that is, technological change, doctrinal, strategic, operational and tactical change, and transformation of military organizational structure. Paradoxically, military transformation takes place while the pace of military technology development decreases, which poses a significant inhibitor. Consequently, only the first RMA stage – computerization – might be recognized as a relatively advanced one, whereas its second stage – networking – is far from this level. The paper's aim is to present the RMA concept and its practical application in transformation of military forces. The paper examines also to what extent expectations emerging from RMA have been fulfilled in armed conflicts over the last two decades.

Abstract Parasitoid wasps are key agents for controlling insect pests in integrated pest management programs. Although many studies have revealed that the behavior of parasitic wasps can be influenced by insecticides, the strategies of patch time allocation and oviposition have received less attention. In the present study, we forced the endoparasitoid Meteorus pulchricornis to phoxim exposure at the LC30 and tested the foraging behavior within patches with different densities of the host, the larvae of the tobacco cutworm Spodoptera litura. The results showed that phoxim treatment can significantly increase the patch-leaving tendency of female wasps, while host density had no impact. The number of oviposition and the number of previous patch visits also significantly influenced the patch time allocation decisions. The occurrence of oviposition behavior was negatively affected by phoxim exposure; however, progeny production was similar among patches with different host densities. Phoxim exposure shaped the offspring fitness correlates, including longer durations from cocoon to adult wasps, smaller body size, and shorter longevity. The findings of the present study highlight the sublethal effects that reduce the patch residence time and the fitness of parasitoid offspring, suggesting that the application of phoxim in association with M. pulchricornis should be carefully schemed in agroecosystems.

A guide microscope is an important part of a certain photoelectric automatic tracking system, and the angle informations acquisition, processing and transmission are the keys for using the guide microscope. According to the application requirements, a kind of angle information processing system of the guide microscope based on STM32 is designed. This system uses the high-performance STM32F103 as the control core and realizes the angle information acquisition, display and transmission by photoelectric encoders, OLED display and RS-485 bus. Then, the hardware design and software debugging are further explained, that it has the simple circuit and convenient development. The running results show the design has the stable and reliable performance. It can meet the requirements.
