Integrated Scenario Planning and Multi-Criteria Decision Analysis Framework with Application to Forest Planning  [PDF]
Livia Bizikova, Emina Krcmar
Open Journal of Forestry (OJF) , 2015, DOI: 10.4236/ojf.2015.52014
Abstract: This paper explores approaches concerning complex forest planning challenges, such as restoration after large-scale disturbances and under climate change. It introduces a new framework that integrates qualitative scenario planning with quantitative multi-criteria decision analysis. This framework allows stakeholders without background in forestry to express their preferences as a set of scenarios that are further assessed for specific forest management goals and activities using multi-criteria models. The assessment of the modelled scenarios created a common understanding for the stakeholders and experts to compare trade-offs between several management options and needed policy choices. The framework was applied in the case study of forest restoration following insect disturbance in British Columbia, Canada. The framework enabled structured stakeholder groups’ interactions such as industry, business associations, local and regional governments, and non-governmental organizations to identify potential restoration options. Different community futures were envisioned by two scenarios: one resembling current conditions and standard practices, while another promoting diversification of the forestry sector. The results indicated that each of the scenarios leads to different consequences for the community measured by levels of economic benefits, total harvest volumes and harvest flows over time. The results also show that the developed framework linking scenarios and multi-criteria decision analyses proved crucial to broaden the discussion on relevant species mixes and management practices, and their implications for the community and policy development.
Preliminary list of horse flies (Diptera, Tabanidae) of Serbia
Stjepan Krcmar
ZooKeys , 2011, DOI: 10.3897/zookeys.117.1328
Abstract: Thirty six species of horse flies (Tabanidae) were previously known from Serbia (Europe). The present faunistic study of horse flies (Tabanidae) has resulted in the recording of the 4 new species Atylotus fulvus (Meigen, 1804); Tabanus miki Brauer in Brauer and Bergenstamm, 1880; Tabanus unifasciatus Loew, 1858; and Heptatoma pellucens (Fabricius, 1776), in the fauna of Serbia. The genus Heptatoma Meigen, 1803 is cited for the first time in the fauna of Serbia. 40 species are currently known from Serbia, belonging to nine genera. The fauna can be considered relatively poorly studied. Most of the species belong to the Boreal-Eurasian type of fauna 23, followed by the South European group with 8 species, the Mediterranean group with 6 species, European group with 2 species and Central European group with 1 species.
Hard ticks (Acari, Ixodidae) of Croatia
Stjepan Krcmar
ZooKeys , 2012, DOI: 10.3897/zookeys.234.3658
Abstract: The present paper is based on original and literature data. In Croatia the first studies on the occurrence of ixodid species were made about 80 years ago. The number of tick species recorded in Croatia considerably increased during the 1950s, 60s, 70s and 80s of the past century. A total of 21 species of hard tick belonging to 5 genera have been recorded in Croatia. Ixodes is the best represented genus, with seven species recorded. Haemaphysalis is represented by six species, followed by Rhipicephalus with four species. Dermacentor and Hyalomma are represented by two species each. The ticks were collected on 47 different host species. Eleven tick species were collected on Bos taurus and Ovis aries, followed by Capra hircus and Equus caballus with 8 species and Canis lupus familiaris with 6 species. On the remaining 42 host species one, two or three tick species were collected. The most widespread tick is Ixodes ricinus which was found on 25 different host species.
Broadband Measuring of Shielding Covers
V. Krcmar
Radioengineering , 2006,
Abstract: The novel method utilizing coupled lines for the dielectric property measurement of shielding covers of composite materials is described. Characteristics of coupled lines designed by two symmetrical strip lines with a common side wall, which is made of the tested material, are mentioned. It allows measuring the dielectric property in the frequency range up to 5 octaves. The circuit analyzer with a high dynamic range is used for parameters evaluation. The method was utilized at the research of the technology of abnormally shaped shielding covers of composite materials.
New Markers of Oxidative Damage to Macromolecules

Journal of Medical Biochemistry , 2008, DOI: 10.2478/v10011-007-0049-x
Abstract: The presence of free radicals in biological material has been discovered some 50 years ago. In physiological conditions, free radicals, in the first place the ones of oxygen and nitrogen, are continuously synthesized and involved in the regulation of a series of physiological processes. The excess of free radicals is efficiently eliminated from the body in order to prevent their toxic effects. Toxic effects of free radicals may be classified into three groups: a) change of intracellular redox potential, b) oxidative modification of lipids, proteins and DNA, and c) gene activation. Lipid peroxidation involving cell membranes, lipoproteins and other molecules leads to the production of primary high-reactive intermediaries (alkyl radicals, conjugated dienes, peroxy- and alkoxyl radicals and lipid hydroperoxide), whose further breakdown generates the secondary products of lipid peroxidation: short-chain evaporable hydrocarbons, aldehydes and final products of lipid peroxidation: isoprostanes, MDA, 4-hydroxy-2, 3-transnonenal and 4,5-dihydroxydecenal which are important mediators of atherosclerosis, coronary disease, acute myocardial infarction, rheumatoid arthritis, systemic sclerosis and lupus erythematodes. Oxidative modification of proteins is manifested by changes in their primary, secondary and tertiary structures. Proteins have a specific biological function, and therefore their modification results in unique functional consequences. The nature of protein modification may provide valid information on the type of oxidants causing the damage. Chlorotyrosyl is a specific marker of oxidative damage to tyrosine caused by HOCl action, which most commonly reflects the involvement of neutrophils and monocytes in oxidative stress, while nitrotyrosyl indicates the presence of higher peroxy-nitrite synthesis. Methyonin and cysteine are the amino acids most sensitive to oxidative stress, carbonyl groups are markers of severe damage caused by free radicals, and di-tyrosyl is the most significant and sensitive marker of oxidative modification made by γ rays. Carbonyl stress is an important form of the secondary oxidation of proteins, where reducing sugars non-enzymatically react with amino groups of proteins and lipids and give rise to the production of covalent compounds known as advanced glycosylated end products (AGE-products). A hydroxyl radical damages the DNA, leading to a loss of base and the formation of abasic sites (AP sites), break of DNA chain and sugar modification. Final lipid peroxidation products (MDA) may covalently bind to DNA, producing the DNA radicals which are responsible for mutations. Measurement of an adequate oxidative stress biomarker may not only point to an early onset of disease, its progression and assessment of therapy effectiveness, but can also help in the clarification of the pathophysiological mechanisms of tissue damage caused by oxidative stress, prediction of disease prognosis and choice of appropriate treatment in
El-Ghibli. Il caso di una rivista di letteratura della migrazione
Antonella Emina
Altre Modernità , 2009,
Abstract: During the XX, literary magazines were the elected places for experimenting in literature and for spreading cultural and political manifestoes, but in the XXI print seems to loose its appeal. Online literary magazines begin publishing important writers and interesting new ones. Besides they deal with the most significant themes of our time. El Ghibli - rivista online di letteratura della migrazione, that really promotes migrant writers in Italy, is elected as a case study. This article describes its essential features and verifies its position among Italian literature and national cultural movements. Moreover, it is a preliminary study of the magazine which is a quite original issue within the Italian milieu.
Compressing Mixed-State Sources by Sending Classical Information
Emina Soljanin
Physics , 2001,
Abstract: We consider visible compression for discrete memoryless sources of mixed quantum states when only classical information can be sent from Alice to Bob. We assume that Bob knows the source statistics, and that Alice and Bob have identical random number generators. We put in an information theoretic framework some recent results on visible compression for sources of states with commuting density operators, and remove the commutativity requirement. We derive a general achievable compression rate, which is for the noncommutative case still higher than the known lower bound. We also present several related problems of classical information theory, and show how they can be used to answer some questions of the mixed state compression problem.

Emina Alibegovic
Mathematics , 2000,
Abstract: We prove that all elements of infinite order in $Out(F_n)$ have positive translation lengths; moreover, they are bounded away from zero. Consequences include a new proof that solvable subgroups of $Out(F_n)$ are finitely generated and virtually abelian and the new result that such subgroups are quasi-convex.
