    Information society imposes globalization and universality of values. In these circumstances, terrorism, institutional political violence which targets trying to achieve the morbid fear of provoking a spectacular way, inappropriately given conditions, becomes a real threat not only to the nations but also to politics on the global level. In 1996, the International Monetary Fund estimated that 2ā€“5% of the worldwide global economy involved laundered money. Today, intelligence activities in preventing and combating terrorism include financial investigations and money laundering for the purpose of financing terrorism, resulting in broadening of the scope of data to the level which makes it impossible for human logical evaluation. Technologies development that enables increasing capacity of speed and the amount of data processing has enabled defining, analyzing and exploring more and more models. This led to the idea of computer experiments and simulations trying to get to more complex planning and forecasting for the purpose of countering terrorism and ā€œdirtyā€ money transaction, as highly dangerous, complex and variable phenomena. This presentation aims at quotation the wide spectrum of mathematically founded fractal concepts suited to generate computer models of anti-terrorist activities. In this sense, the logistic behind the items connected with detecting and recognizing degree of terroristic threat by comparing fractal structure of peopleā€™s faces, fast search through the databases of faces and fingerprints. The speed of searching processes is of vital importance which promotes the crucial importance of compression and data reduction with preservation of regularity. Especially important are analytic forecasting of missing visual data and forms, to supplement the empirical evidences and records. All these operations are possible with higher degree of knowledge utilization and adaptation of virtual reality in the fight against terrorism and different forms of money laundering. The results indicate that the achievements implementation of the concept of fractals depends on substantial prior knowledge, environmental influences, subsystem integration, decentralization and synchronization, and allows us to come up with similar high information technology models, but not necessarily to enable identification of the authentic features of the various anomalies that result in objectively a social consequences. In this sense, we conclude that the application of information technology in the fight against terrorism, based on the concept of fractals has its place in the arsenal of anti-terroristic prevention

    Background/Aim. Meningococcal disease most often manifests itself as meningitis or sepsis. During the course of these diseases, other clinical events sometimes develop such as pneumonia, pericarditis, arthritis, and they are referred to as extrameningeal or systemic manifestations of the meningococcal disease. The aim of this study was to investigate the type and the incidence of particular extrameningeal/systemic manifestations among patients with meningococcal meningitis and sepsis, including time of their onset and the influence on the disease outcome. Methods. The retrospective study of the medical records of 246 patients treated for meningococcal disease over the 25-year period in the Institute for Infectious and Tropical Diseases, Belgrade was conducted. The patients, aged 3 months to 82 years both sexes, were divided into two groups. Results. Out of 246 patients extrameningeal/ systemic manifestations were found in 42 (17.1%) patients: 35 (14.2%) occurred during meningitis, and seven (2.8%) during sepsis. Pulmonary manifestations (mostly pneumonia) were the most prevalent, found in 12 (4.9%) patients, followed by heart involvement in nine (3.6%) patients (mostly pericarditis, in seven or 2.8% patients). Various ophthalmic manifestations occurred in seven (2.8%), arthritis in 4 (1.6%) and sinusitis in six (2.4%) patients. Otitis, multiple renal embolisms with hematuria, osteomyelitis and thrombophlebitis were evidenced in one patient, each. Most of the systemic manifestations (30 patients or 71.4%), developed within the initial three days of the disease (p < 0.01), suggesting direct pathogenic mechanism induced by meningococci per se, while only three (7.1%) developed after seven days, when immune-mediated disease was more likely. Even though these manifestations complicate and prolong treatment of the meningococcal disease, they had no major influence on the disease outcome. Lethal outcome occurred in 2 (4.76%) patients, both with the meningococcal type of the disease. Conclusion. Extrameningeal or systemic manifestations are uncommon complications during the course of both meningococcal meningitis and sepsis. The onset of pneumonia, pericarditis, eye involvement, and arthritis, within the initial seven days of the disease, were most prevalent in the course of meningitis. They had no major influence on the disease outcome

    Buckwheat is an economically important gluten free cereal, and it is a good source of protein, fiber, and energy. The field experiments with buckwheat variety ā€œNovosadskaā€ were set in two experimental years in Pancevo, Serbia. The aim of this study was to determine the most optimal technology for buckwheat production. The study aims were to investigate the effects of (1) row spacing: RS1-25 cm and RS2-50 cm; (2) nutrition variants: (N1) 0 kg haāˆ’1 NPK; (N2) NPK 30 kg haāˆ’1; (N3) NPK 60 kg haāˆ’1; and (N4) NPK 90 kg haāˆ’1; (3) environment: Y1-2018 and Y2-2019; and their interactions on the plant height (PH), number of lateral branches (NoLB), mass of seeds per plant (MSP), number of seeds per plant (NoSP), buckwheat grain yield (GY); and (4) the correlations among these traits. All tested parameters of buckwheat significantly varied across row spacing, environment, and nutrition. The average grain yield in the row spacing, RD1-25 cm, was significantly higher than in the wider spacing, RD2-50 cm, and in 2018 than 2019 as well as with the nutrition NPK applied in the amount of 90 kg haāˆ’1 in relation with all the other nutrition variants. All the studied agronomic traits were positively and strongly correlated with GY

    The Ukrina River (Bosnia and Herzegovina) is a smaller right tributary of the Sava River, whose basin lies between the lower reaches of the Vrbas and Bosna rivers. In addition to being a relatively small basin area, the Ukrina River is characterized by exceptional biological diversity. The appearance of the mayflies (Ephemeroptera) in the summer period of the year also contributes to the biological diversity of the Ukrina River, which makes it the site of this natural rarity. In this study, the threat to the biological minimum and the increased eutrophication of water are considered, as the main factors of disturbing the ecological balance and sustainability of the Ukrina River ecosystem.Rijeka Ukrina (Bosna i Hercegovina) je manja desna pritoka Save, čiji sliv leži između donjih tokova rijeka Vrbasa i Bosne. Pored toga Å”to predstavlja relativno malo slivno područje, rijeku Ukrinu karakteriÅ”e izuzetna bioloÅ”ka raznovrsnost. BioloÅ”koj raznovrsnosti rijeke Ukrine doprinosi i pojava vodenog cvijeta (Ephemeroptera) u ljetnom periodu godine, Å”to je čini lokalitetom odvijanja ove prirodne rijetkosti. U ovoj studiji, razmatraju se ugrožavanje bioloÅ”kog minimuma i eutrofikacija vode kao glavni faktori remećenja ekoloÅ”ke ravnoteže i održivosti ekosistema rijeke Ukrine

    Water plays a vital role in the biosphere as a component of all living beings, participates in photosynthesis, a basic life process on the planet, and represents the environment to a large number of living beings. In water ecosystems, pollutants come from two sources, both natural and anthropogenic. The main anthropogenic sources of pollutants are municipal wastewater, industrial wastewater, and water from agriculture. Microbiological degradation of organic pollutants is the only possibility of their removal from water. In this paper, the possibilities of purification of wastewater are considered, with special emphasis on the role of microorganisms in the process.Voda ima vitalnu ulogu u biosferi kao gradivna komponenta svih živih bića, učestvuje u fotosintezi, bazičnom životnom procesu na planeti, i predstavlja životnu sredinu velikom broju živih bića. U ekosisteme voda, polutanti dospevaju iz dva izvora, prirodnim i antropogenim putem. Glavni antropogeni izvori polutanata su komunalne otpadne vode, industrijske otpadne vode, vode iz poljoprivrede. MikrobioloÅ”ka razgradnja organskih zagađivača, predstavlja jedinu mogućnost njihovog uklanjanja iz vode.

    Mineralne materije su neophodne biljkama za rast i razvoj, kao i za normalno funkcionisanje ljudskog i organizma životinja. Mineralne materije u lance ishrane ulaze preko biljaka, pa je poznavanje i proučavanje mineralnog sastava biljaka izuzetno značajno. Ispitivanje sadržaja mineralnih materija u zrnu kukuruza, u zavisnosti od rastuće količine azota đubriva, obavljeno je u dvogodiÅ”njem periodu, na lokalitetu Zemun Polje, u klimatskim uslovima Istočnog Srema. Na ogledima je primenjena standardna agrotehnika. Hemijski sastav ploda kukuruza, tokom dve godine istraživanja, određivan je u fazi fizioloÅ”ke zrelosti zrna kukuruza. Rezultati istraživanja pokazuju da je, u proseku za ispitivane faktore, sadržaj mineralnih materija u zrnu kukuruza iznosio 1,87%. U prvoj godini istraživanja, utvrđen je veći sadržaj pepela u zrnu za 0,23% u poređenju s drugom godinom. Primenjene količine azota značajno i veoma značajno su uticale na sadržaj mineralnih materija u zrnu kukuruza.Mineral matters are necessary for the growth and development of plants as well as for normal functioning of human and animal organisms. Mineral matters enter the food chains through the plants making the knowledge and study of the mineral content of plants very remarkable. The study of the content of mineral matters in maize grain, depending on the growing quantities of nitrogen fertilizer, has been conducted during a two-year period on the locality of Zemun Polje, in climate conditions of the Eastern Srem. In these experiments, a standard agrotechnique is applied. The chemical contents of the maize yield during the two-year period of the experiment is determined in a phase of the phyisiological ripeness of maize grain. Our research results show that, in the average for the examined factors, the content of mineral matters in maize grain was 1.87%. It is determined that the content of ash in grain was for 0.23% higher in the first year of the experiment than in the second one. The applied quantities of nitrogen had a significant and a very significant impact on the content of mineral matters in maize grain.Radovi sa 33.
