This paper analyzes the influence of the Doppler Effect on the length of time to establish synchronization pseudorandom sequences in radio communications systems with an expanded spectrum. Also, this paper explores the possibility of using secure wireless communication for modular robots. Wireless communication could be used for local and global communication. We analyzed a radio communication system integrator, including the two effects of the Doppler signal on the duration of establishing synchronization of the received and locally generated pseudorandom sequence. The effects of the impact of the variability of the phase were analyzed between the said sequences and correspondence of the phases of these signals with the interval of time of acquisition of received sequences. An analysis of these impacts is essential in the transmission of signal and protection of the transfer of information in the communication systems with an expanded range (telecommunications, mobile telephony, Global Navigation Satellite System GNSS, and wireless communication). Results show that wireless communication can provide a safety approach for communication with mobile robots.

Charging the bottle of high pressure air isolation devices is performed by a high-pressure compressor. The charging time is in function of the compressor capacity and the intensity of the nominal pressure of the air in the bottle. However, in accident situations this time is long and therefore high-pressure accumulators are used where the filling time of the bottle of isolation apparatus has been drastically reduced. Due to the short filling time of the bottle through the air flow, there is a thermodynamic load of bottle material that could endanger the safety of users and other participants in the area. It is therefore necessary to determine the critical parameters of the rapid charge and their intensity.

Alzheimer disease (AD) is common worldwide and almost every case has comorbidities. One of the most common comorbidities of AD is Diabetes mellitus (DM), with or without metabolic syndrome. Both diseases effect nerve tissue and successful treatment would improve the status of the patient. In patients with Alzheimer disease treatment of DM, the treatment could be harmful to the AD, because of that high insulin intake. This may lead to progression of AD. Insulin is considered the best treatment for DM, but insulin therapy could increase comorbidity with AD. No specific therapy for AD is known up to date, so because of that DM is one of the most important risk for AD, concomitant therapy for DM should be planned very carefully. All options of DM therapy should be considered, and different mechanisms of anti-diabetic drugs are preferable. Treatment of AD is more complex metabolic syndrome is present. Any inflammation causes local tissue damage, including brain tissue during AD. Release of interleukins, primarily TNF-α, IL-6, IL-1β in the presence of adipokine leptin, maintains chronic inflammatory status in local brain tissue. Thus, low doses of immunosuppressant therapy should be considered for treatment of AD in future. To delay apoptosis of nerve tissue cells, brain and nerve tissue defend against free oxygen radicals and improve metabolic status.

Introduction: Changes in lifestyle can significantly affect the management of good glycemic control and target values of blood pressure and lipids. Objective: To determine the achievement of target values of glycated hemoglobin (HbA1c), blood pressure and lipids, in participants with type 2 diabetes, who used a proper diet and controlled physical activity. Method: The study was a prospective study, conducted on participants with type 2 diabetes, from 01 October 2012 until 31 October 2013, at the Primary Health Center Banja Luka, by 60 family medicine teams. At the beginning of the study, all participants had individual counseling on lifestyle changes, eating habits, and regulation of body weight. Results: The study included 591 participants with the type 2 diabetes. At the beginning of the study, 49.92% of participants adhered to the proper diet, and at the end 76.65% of them (p<0.001). Targeted value of HbA1c ≤ 6.5% was registered in 61.70% participants at the beginning of the study and at the end of the study in 86.62% participants (p <0.001); the target value of blood pressure (≤130/80 mmHg) was registered in 56.21% at the beginning, and at the end in 79.91% (p<0.002). Targeted value of total cholesterol was registered in 59.61% at the beginning of the study, and at the end of the study in 81.91% subjects (p <0.003). Conclusion: In patients with type 2 diabetes individual counseling about lifestyle changes helps to attain optimal values of HbA1c, blood pressure, and serum lipid levels.
