Feasibility of a Hybrid Brain-Computer Interface for Advanced Functional Electrical Therapy

We present a feasibility study of a novel hybrid brain-computer interface (BCI) system for advanced functional electrical therapy (FET) of grasp. FET procedure is improved with both automated stimulation pattern selection and stimulation triggering. The proposed hybrid BCI comprises the two BCI control signals: steady-state visual evoked potentials (SSVEP) and event-related desynchronization (ERD). The sequence of the two stages, SSVEP-BCI and ERD-BCI, runs in a closed-loop architecture. The first stage, SSVEP-BCI, acts as a selector of electrical stimulation pattern that corresponds to one of the three basic types of grasp: palmar, lateral, or precision. In the second stage, ERD-BCI operates as a brain switch which activates the stimulation pattern selected in the previous stage. The system was tested in 6 healthy subjects who were all able to control the device with accuracy in a range of 0.64–0.96. The results provided the reference data needed for the planned clinical study. This novel BCI may promote further restoration of the impaired motor function by closing the loop between the “will to move” and contingent temporally synchronized sensory feedback

Towards an Embodied Sociology of War

While sociology has historically not been a good interlocutor of war, this paper argues that the body has always known war, and that it is to the corporeal that we can turn in an attempt to develop a language to better speak of its myriad violences and its socially generative force. It argues that war is a crucible of social change that is prosecuted, lived and reproduced via the occupation and transformation of myriad bodies in numerous ways from exhilaration to mutilation. War and militarism need to be traced and analysed in terms of their fundamental, diverse and often brutal modes of embodied experience and apprehension. This paper thus invites sociology to extend its imaginative horizon to rethink the crucial and enduring social institution of war as a broad array of fundamentally embodied experiences, practices and regimes

AGROTECHNICAL ASPECTS OF SOIL CULTIVATION AND FERTILISATION OF CULTIVATED PLANTS

Physically, chemically, microbiological soil properties and mineral nutrition are key elements in plant cultivation technology. Yield of cultivated plants is dependent from many production factors. Yield will be defined by the production factor which was longer in the minimum. It can be human knowledge, or irresponsibility, or carelessness. Soil compaction is affecting yield. On compacted soils sugar beet yield can decrease for 17.8 tha-1, and sugar yield for 2.09 tha-1. Maize yield decreasing can ranged from 354-2990 kgha-1, and wheat yield decreasing can be from 320-1850 kgha.1.Reason for this yield decreasing is lower soil water capacity ( to 228000lha-1) and lower microbiological soil activity ( 270 times). Cultivation can improve these properties and increase yield. Optimal tillage depth for sugar beet is 30-35 cm, with sub soling. Three layer tillage yield can be increased for 10.2 tha-1in trial conditions, and root yield for 5.5 tha- 1 ,in production conditions. Soil tillage for sugar beet should be done in October. Previous or later tillage can decrease yield for 4.2 tha-1. Maize tillage should be at 25 cm-deeper tillage has no effect on yield increasing. Wheat tillage should be at 15 cm. Fertilization is most important productive factor. Fertilization with P and K should be readjust to soil productivity, field yield potential, cultivar/hybrid potential, weather conditions of the year and destination of harvest residues. When these elements are defined, planned yield and soil fertilization can be determined. Needed amounts of P and K and 30-60% nitrogen amount are necessary before primary tillage in autumn. Remaining nitrogen amounts for strna zita must be applied during the fertilization, and calculation should be based on M-min method. Yield height will be defined by nitrogen position per soil profile depth, and by winter precipitation reserve. Nitrogen for jare okopavine (excepting soybean) should be in 60-120 cm layer

THE IMPORTANCE OF SERBIA’S TRADE POLICY IN LIBERALIZATION CONDITIONS

Trade policy should be directed towards the creation of conditions for the smooth functioning of the market and for full respect for the rules of the market game. It is a common opinion among economic policy makers that liberalization leads to more efficient allocation and use of resources, because the domestic economy is exposed to the discipline of the world market and the influence of modern technology. It is often emphasized that rapid liberalization of imports can cause balance of payments difficulties and dislocations in the economy, unless combined with effective measures to increase competitiveness and improve exports. It is recommended that the liberalization process be gradual. A radical liberalization process can have a very negative impact on the balance of payments. The biggest problem of Serbian exports is the lack of recognizable products that could be competitive in the world market with price and quality. One of the key directions of foreign trade policy in the coming period is to direct companies to new markets. Today Serbia has great experience in many segments of transition that have been taking place in other countries. Taken examples of the countries that went through the transition and became EU members, significant activities have been undertaken to improve foreign trade policy. The aim of this paper is to analyze the trade policy and the Serbian transition process, and to point out possible measures and activities that would contribute to the faster and sustainable development of the Serbian economy
