"Lepenac i njegove pritoke"
This article reconstructs Albert Camusās notion of the absurd in order to elucidate his critique of historical teleology. In his life and work, Camus endeavoured to develop a fallibilist historical sensibility suitable to a cosmos shorn of meaning, which led him to reject ideas of progress and their traces of messianism when elaborating his treatment of rebellion. By making use of Camusās ideas about the absurd and rebellion, I suggest that these two themes productively unsettle contemporary cosmopolitanism as a teleological orthodoxy of human progress and fruitfully if paradoxically lie at the heart of a concept of cosmopolitanism āwithout hopeā.PostprintPeer reviewe
Mean field approximation for noisy delay coupled excitable neurons
Mean field approximation of a large collection of FitzHugh-Nagumo excitable
neurons with noise and all-to-all coupling with explicit time-delays, modelled
by stochastic delay-differential equations is derived. The resulting
approximation contains only two deterministic delay-differential equations but
provides excellent predictions concerning the stability and bifurcations of the
averaged global variables of the exact large system.Comment: 15 pages, 3 figure
Implementation of climate change science in viticulture sustainable development planning in Serbia
Growing interest in Serbia in adaptation of viticulture to climate change emerged from a recorded positive impact of summer increased draught on domestic wine quality. Another motivation is that viticulture has been recognized as one of the fastest developing agricultural sectors in Serbia and, to contain its growing potential, it is crucial to provide basis for its future sustainable development. Prioritization and implementation of adaptation measures in practice require reliable assessment of climate projections. For climate change impact assessment is used high resolution multi-model ensemble of nine regional climate models simulations, bias corrected, with two most probable future scenarios of GHG emissions RCP4.5 and RCP8.5, for the period 2016-2100. Analysis has been done for the near future, mid-century and end of the century periods. The periods are defined according to the IPCC 5th Assessment Report, which enables comparison of climate change impacts with a wider region, and preferably motivate future international collaboration and knowledge exchange
PHARMACOLOGICAL EXERCISE MIMETICS IN THERAPY: DELUSION OR FUTURE?
The increase in the prevalence of a large number of metabolic disorders is attributed to the sedentary lifestyle associated with increased energy intake of food. Scientists warn that our genes are not selected for a sedentary existence and that the complex homeostatic system is being seriously undermined. Regular physical activity induces a number of physiological adaptations both within skeletal muscle and the whole organism, which have positive effects in the prevention and treatment of many metabolic disorders. Recognizing the impact of these beneficial effects of physical activity on health outcomes, and taking into account the trend of inactivity population, researchers have focused on the active substances that mimic or potentiate the effects of exercise without the actual energy consumption, and big pharmaceutical companies see a potentially huge market and profit in this. This paper discusses the real possibility and potential of pharmacological mimetic of exercise in the treatment of metabolic diseases
Rootstocks Influence on Leaf Surface and Vegetative Potential of 'Prokupac' Grape Cultivar
Research was conducted at the experimental field on the Faculty of Agriculture in Belgrade. The research subject was Serbian autochthonous black wine cultivar 'Prokupac', grafted on three different rootstocks: Berlandieri x Riparia Kober 5BB, Berlandieri x Riparia SO4 and Sasla x Berlandieri 41B. The research showed that rootstock 41B had the greatest impact on leaf area increase (212.43 cm(2)) and K 5BB the lowest (192.02 cm(2)). During the several research years on the total shoots length rootstock K 5BB had the greatest influence (181.5 cm), while the other two rootstocks showed smaller total shoot increase of 172.8 cm (K 5BB) and 164.1 cm (SO4). Percent of ripe part on the shoot in the research period (1994-2000) was higher on rootstock 41 B (89.6%) compared to rootstocks K 5BB (86.5%) and SO4 (87.3%). On the same rootstock in the research period slight increase in shoots length was found during the growing compared to the other two rootstocks (182.6 to 217.0 cm). The highest weight of pruned shoot per vine was observed on the rootstock K 5BB (430.33 g), after that on rootstock 41B (370.23 g) and the lowest on the rootstock SO4 (329.16 g) which is rated as statistically significant
Ampelographic characterization of Vitis cv "Prokupac" clones by multivariate analysis
Twenty-five Prokupac clones were included in the research. The aim of this study was to: examine the variability of morphological traits within the clone collection, calculate the correlation among characteristics, detect associations among clones, identify the most useful variables for discrimination among clones and recommend clones suitable for further exploitation. Statistical analysis was performed based on the average values obtained from a three year long period. Relationship among the traits was presented with a correlation analysis which was done by using Pearson correlation coefficients. Cluster analysis was performed by applying Ward's method and Euclidean distances. The overall mean values showed high level of morphological variability. The highest level of variation was found in the number of berry seeds. Based on cluster analysis clones divided into three clusters I, II and III which include 7, 12 and 6 clones, respectively. Maximum Euclidean distance was observed between the clones 42/2 and 43/8, and minimum distance was observed between the clones 40/8 and 43/7. Parameters with high discriminating values were those related to bunch and berry size and structure. Most clones are perspective for further investigation and vine production, clones 40/4, 41/1 and 43/8 have large bunches and can be recommended as consummation grape
Clinical manifestations of atopy in children up to two years of age
Background/Aim. Atopic diseases such as atopic dermatitis, allergic rhinitis and asthma have had increased prevalence during the past decade and nowadays occur in every third child in developed countries. The aim of the study was to determine frequency and type of atopic diseases at the age of two, as well as the importance the total IgE antibodies concentrations have in diagnosis and prognosis of the disease. Methods. The study involved 175 children up to two years of age. Allergy-like symptoms were found after surveying their parents and pediatric medical records. Using the fluorescence immunossay (FIA) method, total IgE antibodies concentrations and specific IgE antibodies (Phadiatop infant) were determined on an Immunocap 100 Dyagnostic System. Results. One or more allergy-like symptoms accounted for 57.7% of findings in children under the age of two, whilst in 19.4% the existence of IgE-related allergic diseases was found. Atopic diseases usually have clinical manifestations of atopic dermatitis (11.4%), IgE-bound wheezing/asthma (10.8%) and food allergies (7.4%), and to much lesser extent those of allergic rhinitis (3.4%) and urticaria (1.7%). The significantly higher total IgE antibodies concentrations were found in children with allergy-like symptoms (p < 0.0005) (cut-off 15.15 kU/L, sensitivity 76.5% specificity 71.6%). Conclusion. Almost 20% of two-year-old children have any of clinically manifested allergic diseases, with atopic dermatitis and IgE wheeze/asthma being predominant. The higher total IgE antibodies concentration is a good marker for sensitization in children with allergy-like symptoms
