Screening for Diabetes among Roma People Living in Serbia

Aim To investigate the prevalence of diabetes in the Roma population in Serbia. Methods We screened 11 urban and 8 rural Roma communities from October 2006 to May 2008 for the presence of diabetes. Blood glucose values, name, age, sex, presence of diabetes, family history, and obesity were recorded. Results We analyzed the data from 1465 Roma people, 953 women and 512 men (785 in urban and 680 in rural communities), with mean age of 42.42 ± 15.69 years. Abdominal obesity was present in 600 (41%) participants. Eighty seven participants (5.9%) already had diabetes and there were 76 (5.2%) newly discovered cases of diabetes type 2. Participants with diabetes were significantly older (F = 28.33; P < 0.01). Family history for diabetes was positive in a third of participants. The risk for diabetes was 3.48 times higher in participants with positive family history (odds ratio [OR], 3.47; 95% confidence interval [CI], 2.37-5.1; P < 0.01). Abdominal obesity was less frequent in healthy participants than in participants with diabetes (X2 = 32.55; P < 0.01). The risk of diabetes in participants with abdominal obesity was 2 times higher than in the non-obese (OR, 2.11; 95% CI, 1.24-3.55; P < 0.01). Diabetes was significantly more present in urban communities (X2 = 25.20; P < 0.01). The risk of developing diabetes was 3.65 times higher in participants from urban settlements (OR, 3.64; 95% CI, 1.99- 6.66; P < 0.01). Conclusion Prevalence of diabetes in the Roma people living in Serbia may possibly be higher than in the general population of Serbia and needs further investigation

Steel frame versus rack supported warehouse structures

Čelične okvirne konstrukcije hala sa stupovima i krovnim gredama ili rešetkama su najzastupljeniji stil građenja skladišnih hala za proizvodne i distributivne potrebe. Ovisno o namjeni, klasične skladišne hale su po potrebi opremljene različitim tipovima regalne konstrukcije. Konstrukcija samonosećeg paletnog regalnog skladišta, kao poseban vid montažnog objekta, uglavnom se sastoji od elemenata regalnog sustava koji nosi krov i zidove, a istovremeno služi i za skladištenje materijala. Svi elementi takve čelične konstrukcije su izrađeni od tankostjenih profila koji omogućuju potrebnu jednostavnost i nisku cijenu konstrukcije. U ovom radu su prezentirana dva sustava građenja skladišta. Provedena je usporedna analiza dva sustava s aspekta procesa izgradnje, tehničke izvedivosti i kapaciteta, vremena izgradnje, ekonomske isplativosti i fleksibilnosti u uporabi.Steel frame buildings based on vertical steel columns and horizontal beams or lattice are the most common style for industrial and distribution warehouses. Depending on the use, these typical warehouses are equipped with various types of free standing racks. Construction of self-supporting pallet racking warehouse, as a special form of pre-fabricated building, consists mainly of the racking system elements supporting the roof and walls, and also serves to storage materials. All elements are made of structural thin-walled steel profiles that provide the necessary lightness and low cost of construction. In this paper two systems of warehouse buildings are presented. Two structural designs are analysed and compared in terms of their construction process, technical feasibility with storage capacity, time advantage, economic viability and flexibility of usage

Osnova za projektovanje Drive-in i drive-through regala

Drive-in and drive-through accumulation racking systems are recommended for great amounts of goods with few various units. According to the "First In, Last Out" - FILO and "First-In, First-Out" - FIFO principle, the palletized load unit are stored into deep tunnels accessible by forklift trucks for handling operations. This allows exploiting as much room as possible and eliminating the aisles traditionally required for manipulating purposes. This paper provides basic information on the requirements, design and use of drive-in and drive-through racking systems in accordance with current regulations and standards. Minimum required clearances and tolerances due to all influencing parameters for manually operated systems are discussed.Publishe

ASSESSMENT OF THE DRUM REMAINING LIFETIME IN THERMAL POWER PLANT

In this paper analysis of stress and thermal-elastic-plastic strain of the drum is performed. Influence of modified thickness, yield stress and finite element model of welded joint between pipe and drum on assessment of the remaining lifetime of the drum in the thermal power plant is analyzed. Two analyses are compared. In the first, drum is modeled by shell and by 3D finite elements with projected geometrical and material data of drum. Then, the drum is modeled by shell and by 3D finite elements with modified thickness and yield stress. The analysis show that detailed modeling of stress concentration zones is necessary. Adequate modeling gives lower maximal effective plastic strain and increased number of cycles and, in that case, 3D finite elements are better comparing to shell finite elements
