This work gives the method of transient time determination of the belt conveyor in the case of its start up in the example of a belt conveyor for ore at the open pit “Veliki Krivelj” with capacity of 2000 t/h. The analysis was made by calculation procedure and it represents a universal calculation method of conveyor belts whose results are indispensable for verification the reliable operation of selected electric motors during the start up of belt conveyor. Also, technical characteristics of all components of drive units are given as well as their layout.

Introduction. Chronic,low-grade infl ammation is important in the development and progression of type 2 diabetes mellitus (T2DM). Indicators of increased infl ammatory activity include elevated values of circulating acute phase proteins like C-reactive protein (CRP) and fi brinogen. The aim of the study was to test sex-related differences in CRP and fi brinogen blood levels in T2DM patients. Patients and Methods. The cross-sectional study included 40 T2DM patients, both sexes (19 males and 21 females), median age 70 (36-90) years. Patients were hospitalized at the Clinic of Endocrinology, Clinical Center University of Sarajevo. The fasting glucose levels, glycated haemoglobin, fi brinogen and CRP in the blood of T2DM patients were determined by standard laboratory methods. The data were analysed by statistical software SPSS 19. Results. The median values of CRP and fi brinogen in blood were not statistically different between female and male T2DM patients, although values had tendency to be higher in female patients [17.30 mg/L (3.40-61.35) vs. 9.60 mg/L (3.50-28.90); p=0.573]; [5.70 g/L (4.20-6.35) vs. 3.80 g/L (3.60-6.00); p=0.078]. A positive correlation between CRP and fi brinogen was found in samples from female T2DM patients (rho=0.606;p<0.01). Conclusion. Elevated CRP and fi brinogen indicate the presence of infl ammation in T2DM patients. Female patients had higher values of both infl ammatory markers in blood in comparison to males, but we did not prove statistically signifi cant sex-related differences.

Recommendations for prevention of coronary heart disease are measures that are available to both individuals and entire populations to detect diseases and faster and more successful intervention, respectively a measure directed against the progression or recurrence of diseases in people with established disease. Secondary prevention of coronary heart disease seemed to measures aimed at preventing re lapses and progression of atherosclerosis in people who already have developed disease.Modification of coronary risk factors is a key part of secondary prevention of coronary bolesti.The main risk factors remain important predictors of long-term prognosis in patients with coronary artery disease. New studies on the application of measures of secondary prevention of coronary heart disease showed a high prevalence of adverse lifestyle characteristics, other risk factors and inadequate use of prophylactic drugs in patients with coronary disease. Inadequate treatment of risk factors in coronary patients is similar in Europe and other parts of the world.
