Atrial flutter (AFL) is typically characterized by electrical activity propagating around specific anatomical regions and it is usually treated with catheter ablation. In this study, we modeled the electrical propagation pattern of AFL using directed network mapping (DNM). DNM is a recent method that makes use of network theory (NT) to characterize the electrical propagation [1, 2], such as the identification of cycles and focal points. The network is composed by nodes and edges resembling electrodes located across the atrial surface and the direction of the electrical propagation from one electrode to another.

The study problematizes the democratic consequences of globalization and conceptualizes attention to the fact that an adversary process of disintegration occurs in parallel with integration and globalization. It further distinguishes between globalization as an objective historical process and globalism as adverse domination. In order to reverse the resistance against globalization, active policies are required in opposite directions: strengthening democracy above the level of the nation-state and investing efforts in local economic development. Globalization can regulate through international agencies, although it cannot be sufficiently democratic. Globalization causes the weakness of national borders, restriction of state domination on information stream and traditional borders, and broadcast of democratic values by new communication instrumentals that stable democracy to favorite aim and too success method in people minds. However, globalization strengthens democratization, political, cultural, and social transformation. World citizenship necessarily presupposes creating a new political identity, and cosmopolitanism must show how this identity can be achieved without a democratic deficit or a bureaucratic-oligarchic plethora. It is essential to build a theory of globalization by understanding what is arising in various spheres separately. The world cannot be governed based on several abstract ideological principles such as liberalization, privatization, and monetarism insofar as the hegemonism policies' philosophy. After a certain level of development, the Soviet Union could no longer be successfully managed from one center, converting even less powerful globally. The consequences of centralism are rough, inadequate, belated solutions that do not consider the specifics (historical, cultural, sociopolitical, economic, psychological) of regions (Balkans, Muslim World, Latin America) and any particular nation-state. Each of which must have a different development strategy. The events like Arab Spring should advance for democratization in non-democratic regions because freedom, equality, and justice are common values between people that are hidden in democracy nature.

Previous research has shown that there are allelopathic interactions between plants, releasing allelochemicals for which it is still unknown whether they are randomly generated or transmitted from generation to generation. In this paper, the influence dried ragweed leaves (Ambrosia artemisiifolia L.) aqueous extract of different concentrations: concentrated extract (10%), extract diluted to 1/2 (5%); 1/4 (2.5%) and 1/8 (1.25%) on germination and growth of peas and beans was monitored. The results showed that the increased concentration of ragweed extract inhibited germination, prolonged germination time and decreased the germination index of both test plant species compared to the control. The ragweed extract (concentrated and 1/2) reduced the growth of shoots and roots compared to the control (by more than 50%), with the inhibitory effect being more visible on young pea plants compared to beans. The results of the research showed that the presence of ragweed as a weed in the field significantly reduces the germination and growth of cultivated plants, which is why care should be taken to suppress and remove it in a timely manner.

The development of science and technology introduces new approaches in plant breeding and various methods to increase plant productivity. One of the latest methods is the implementation of an environmentally friendly technique of using a pulsed low-frequency electromagnetic field (PEMP). The paper presents the results of the influence of the electromagnetic stimulation of soybean seeds on grain weight per plant, weight of 1,000 grains and grain yield in different agroecological conditions. In the three-year research, in the period from 2013 to 2015, the soybean variety Valjevka was used, grown with different amounts of fertilizers (control - without fertilization, 750 kg/ha and 1300 kg/ha). Before sowing, the seed was subjected to PEMP stimulation in variants: control - without stimulation and alternating magnetic field stimulation (PEMP) with induction of 30 mT and exposure time of 15 minutes. The average grain weight per plant during seed stimulation was 11.53% (12.09) higher than without PEMP (10.84). The weight of 1,000 grains with PEMP was 155.99 g, which was 2.06% higher than the weight of 1,000 grains of the variant without PEMP (152.83 g). The average soybean grain yield for all three years of research with seed stimulation was 4.85% higher (3,481.25 kg/ha) than without PEMP (3,320.14 kg/ha). Stimulation of seeds with PEMP has economic justification given the growth of soybean prices on the world stock market. The results show that the PEMP treatment of soybean seeds can significantly affect soybean grain yield and counteract side effects such as drought and lack of fertilizers.

Ancient Roman concrete constitutes many ancient structures that remain standing; however, little is known about how it has remained durable. Here, we investigate the mortars used in ancient water bearing infrastructure such as aqueducts, cisterns, and baths. In these structures, crushed ceramics are used as a pozzolanic additive on surfaces in continuous or frequent contact with water. The ceramic-lime mortars are probed using a multi-scale characterization approach including SEM-EDS and Raman microspectroscopy. The analysis shows the role of ceramics within these structures as a source of aluminosilicates, mapping the presence of both pozzolanic and post-pozzolanic phases. A hybrid binder consisting of cementitious hydrates and calcite is mapped at the interface of the ceramics and evidence of post-pozzolanic densification of pores and cracks is observed. Comparison across structures shows that material selection and chemistry benefit the infrastructure applications. Understanding these ancient materials provides inspiration for new, durable infrastructure materials.

 merima.ibisevic@untz.ba ABSTRACT: Origanum compactum (Lamiaceae) is an endemic species of oregano from Morocco, and the main components are carvacol and thymol, which are considered to have antimicrobial activity. Essential oils can be unstable, poorly soluble in water and poorly delivered to target cells. The incorporation of essential oils into liposomes can reduce their irritant effect, while at the same time prolonging the action of the preparation itself as well as increasing its effectiveness. The aim of our study was to investigate antimicrobial activity of liposomal and non-liposomal vaginal suppositories, and see if there are any differences in antimicrobial activity. Examination of the antimicrobial activity of vaginal suppositories was examined in the same way as the antimicrobial activity of the essential oil, by the disk diffusion method. There were used standard bacterial strains from ATCC collection: Staphylococcus aureus ( S. aureus ) ATCC 25923, Enterococcus faecalis ( E. faecalis ) ATCC 51299, Escherichia coli ( E. coli ) ATCC 25922, Candida albicans ( C. albicans ) ATCC 10231. Liposomal vaginal suppositories had a smaller inhibition zones probably due to the slower release of active components, but still have an advantage over non-liposomal vaginal suppositories because they reduce the irritating potential of the

Telekia speciosa (Schreb.) Baumg., Asteraceae, is widespread in Eastern and Central Europe and the Balkan Peninsula. Previous phytochemical investigations have revealed T. speciosa as a rich source of sesquiterpene lactone -isoalantolactone, especially in its underground parts. The aim of the present study was to analyze the essential oils from aerial and underground parts of T. speciosa and investigate their antimicrobial activity. Chemical composition of essential oils was determined by GC-FID/MS method leading to the identification of 67 compounds in total, with 15.77 % oxygenated monoterpenes, 7.77 % sesquiterpene hydrocarbons, 49.14 % oxygenated sesquiterpenes, and 12.37 % other compounds from aerial parts, and 3.80 % oxygenated monoterpenes, 3.13 % sesquiterpene hydrocarbons, 90.33 % oxygenated sesquiterpenes from underground parts essential oil. The main components from aerial parts were (E)-nerolidol (11.54 %) and caryophyllene oxide (10.54 %), while isoalantolactone was the predominant component from essential oil underground parts (83.41 %). The minimum inhibitory concentration (MIC), minimum bactericidal/fungicidal concentration of the essential oils were evaluated against six strains of bacteria and two strains of fungus using in vitro microdilution method. Both oils presented antimicrobial properties against pathogens Staphylococcus aureus, Bacilus cereus, Pseudomonas aeruginosa, Escherichia coli, and Candida albicans. Inhibition of growth of tested microorganisms by T. speciosa underground parts essential oil was achieved with MICs ranging from 1.0 to 11.0 mg mL -1 , while MICs of aerial parts essential oil varied from 4.0 to 30.0 mg mL -1 . The obtained results contribute to the knowledge of antimicrobial properties of T. speciosa, which support traditional uses underground parts of the plant.
