Authors: Fragoulis Georgios , Trevisan Marco , Di Guardo Andrea , Sorce Andrea , van der Meer Markus , Weibel Franco , Capri Ettore
Published: February 2009

Organic viticulture is an important part of the European Union organic farming sector, and, according to the most recent surveys, 1.5% of European Union wine originates from organic farms, with an upward trend. This paper describes an environmental impact of an organic viticulture indicator (EIOVI) that can be reliably used in the management of organic vineyards. The EIOVI can be used as a decision support system for farmers and other property managers by evaluating the potential ecological impact of their choices, thus optimizing management options. The tool allows the simulation of vineyard management based on six agricultural and ecological modules. The EIOVI is a fuzzy expert system that calculates the relationship between the modules on the basis of a set of 64 decision rules. Initial testing (validation) has been performed using 20 simulations for six Swiss wine‐growing estates. The results of these tests were promising; the EIOVI motivates managers to consider the wine‐growing estate as a whole by subsummarizing all aspects of management. The visualization of results is very tangible and clearly shows that the use of this indicator could improve the management of the vineyard. With some improvements, the EIOVI will be a helpful assessment tool for vine growers, consultants, environmental agencies, and scientists.

Published: February 2009

Strong acid solutions have been widely used in acid traps to determine concentrations of ammonia in ambient air or exhaust air stream. A literature survey indicates the method has a long history and a wide variation in use. Through a series of studies, this paper examines several factors including volume of the acid, depth of the acid, and airflow rate; that might affect the efficiency of sulfuric acid traps and recommends steps researchers and other users may take to ensure reliable results from this method. The results from these series of studies indicate: (i) an inverse relationship between the efficiency of the acid traps and the amount of ammonia to be trapped even when the capacity of the acid trap is excessively greater than the maximum theoretical stoichiometric capacity needed to dissolve all of the ammonia, (ii) for the same volume of acid, the efficiency of the acid trap increased with the acid depth but overall, the efficiency at any given acid depth decreased as the amount of ammonia through the trap increased, and (iii) at the two airflow rates examined in this study (0.5 and 1.0 L/min) the efficiency of the acid traps decreased at similar rates as the concentration of ammonia in the sample air increased but the efficiency of the trap was significantly higher at the lower airflow rate. To obtain reliable measurements from this method, therefore, multi‐point calibrations within the entire range of target measurements is recommended to provide accurate corrections of the measurements.
Methane Oxidation in Landfill Cover Soils, is a 10% Default Value Reasonable?
Authors: Chanton Jeffrey P. , Powelson David K. , Green Roger B.
Published: February 2009

We reviewed literature results from 42 determinations of the fraction of methane oxidized and 30 determinations of methane oxidation rate in a variety of soil types and landfill covers. Both column measurements and in situ field measurements were included. The means for the fraction of methane oxidized on transit across the soil covers ranged from 22 to 55% from clayey to sandy material. Mean values for oxidation rate ranged from 3.7 to 6.4 mol m−2 d−1 (52–102 g m−2 d−1) for the different soil types. The overall mean fraction oxidized across all studies was 36% with a standard error of 6%. The overall mean oxidation rate across all studies was 4.5 mol m−2 d−1 ± 1.0 (72 ± 16 g m−2d−1). For the subset of 15 studies conducted over an annual cycle the fraction of methane oxidized ranged from 11 to 89% with a mean value of 35 ± 6%, nearly identical to the overall mean. Nine of these studies were conducted in north Florida at 30° N latitude and had a fraction oxidized of 27 ± 4%. Five studies were conducted in northern Europe (∼50–55° N) and exhibited an average of 54 ± 14%. One study, conducted in New Hampshire, had a value of 10%. The results indicate that the fraction of methane oxidized in landfill greater than the default value of 10%. Of the 42 determinations of methane oxidation reported, only four report values of 10% or less.
Plasmid-mediated multiple antibiotic resistance of Escherichia coli in crude and treated wastewater used in agriculture
Authors: Pignato S. , Coniglio M. A. , Faro G. , Weill F. X. , Giammanco G.
Published: February 2009

A total of 273 Escherichia coli isolates from raw and treated municipal wastewaters were investigated to evaluate the frequency and persistence of antibiotic resistance and to detect the occurrence of conjugative R plasmids and integrons. The highest resistance rates were against ampicillin (22.71%), tetracycline (19.41%), sulfamethoxazole (16.84%) and streptomycin (14.28%). Multiple antibiotic resistance was present in 24.17% of the isolates. Several multiple antibiotic-resistant isolates proved to be able to transfer en bloc their resistance patterns by conjugative R plasmids with different molecular sizes and restriction profiles. Class 1 integrons of 1 or 1.5 kbp were found in 5 out of 24 representative multiresistant E. coli isolates. Although wastewater treatments proved to be effective in eliminating Salmonella spp. and in reaching WHO microbiological standards for safe use of wastewater in agriculture, they were ineffective in reducing significantly the frequency of plasmid-mediated multiple antibiotic resistance in surviving E. coli. Since multiple antibiotic-resistant bacteria carrying integrons and conjugative R plasmids can constitute a reservoir of antibiotic-resistance genes in wastewater reclaimed for irrigation, risks for public health should be considered. Bacterial strains carrying R plasmids and integrons could contaminate crops irrigated with reclaimed wastewater and transfer their resistances to the consumers' intestinal bacteria.
Endocrine disrupting compounds (EDCs) and pharmaceuticals and personal care products (PPCPs) in the aquatic environment: implications for the drinking water industry and global environmental health

Published: February 2009

Endocrine disrupting compounds (EDCs) and pharmaceuticals and personal care products (PPCPs) are a group of chemical compounds with diverse physical and chemical properties. Recent studies have indicated undesired effects of EDCs and PPCPs at their reported trace concentrations (ng l−1 to μg l−1). This paper reviews the current knowledge on the sources, properties, occurrence and health impacts of EDCs and PPCPs, and their removal from drinking water using ozonation and ozone/hydrogen peroxide-based advanced oxidation. The paper also examines the potential threats posed by these chemicals to drinking water and public health. While these compounds are known to have adverse effects on ecosystem health, notably in the fish population, a similar link is yet to be established between ingestion of these compounds through drinking water and human health. In addition, data on the effectiveness of existing methods for the removal of these compounds are not conclusive. Further studies are required to characterize risks, and also to evaluate and optimize existing removal processes. Also concerted international effort is urgent to cut down the risk of exposure and restrain the production and marketing of toxic chemicals.

Published: February 2009

We examined whether the average water residence time, the time it takes water to travel from the treatment plant to the user, for a zip code was related to the proportion of emergency department (ED) visits for gastrointestinal (GI) illness among residents of that zip code. Individual-level ED data were collected from all hospitals located in the five-county metro Atlanta area from 1993 to 2004. Two of the largest water utilities in the area, together serving 1.7 million people, were considered. People served by these utilities had almost 3 million total ED visits, 164,937 of them for GI illness. The relationship between water residence time and risk for GI illness was assessed using logistic regression, controlling for potential confounding factors, including patient age and markers of socioeconomic status (SES). We observed a modestly increased risk for GI illness for residents of zip codes with the longest water residence times compared with intermediate residence times (odds ratio (OR) for Utility 1 = 1.07, 95% confidence interval (CI)=1.03, 1.10; OR for Utility 2 = 1.05, 95% CI = 1.02, 1.08). The results suggest that drinking water contamination in the distribution system may contribute to the burden of endemic GI illness.
Identification of microbial faecal sources in the New River in the United States–Mexican border region

Published: February 2009

Water samples were analysed to differentiate human and animal faecal contamination of the New River, Mexico/USA, by genotyping bacterial viruses detected in the samples. From 46 water samples collected from the New River, 372 plaques of male-specific coliphages were isolated and genotyped; 44% of the plaques were identified as F-RNA coliphages and further characterized into four groups. Group I was the most prevalent (56%), followed by group IV (25%), group III (10%) and group II (9%). Group III coliphages were only detected at the sampling site in the vicinity of the international boundary, indicating human faecal contamination. As the New River traverses through the US region, groups I and IV coliphages were predominantly identified, but no human-specific genotypes were detected. The study also found that water temperature influenced the prevalence of the relative proportions of F-RNA coliphages in the environmental water samples. The strategy used in this study appears to be a practical and reliable tool for monitoring and distinguishing between human and animal faecal contamination.

There appears to be very good epidemiological evidence for a relationship between chlorination by-products, as measured by trihalomethanes (THMs), in drinking water and bladder cancer, but the evidence for other cancers, including colorectal cancer appears to be inconclusive and inconsistent. There appears to be some evidence for a relationship between chlorination by-products, as measured by THMs, and small for gestational age (SGA)/intrauterine growth retardation (IUGR) and preterm delivery, but evidence for other outcomes such as low birth weight (LBW), stillbirth, congenital anomalies and semen quality appears to be inconclusive and inconsistent.

The overall aim of the HIWATE study is to investigate potential human health risks (e.g. bladder and colorectal cancer, premature births, SGA, semen quality, stillbirth, congenital anomalies) associated with long-term exposure to low levels of disinfectants (such as chlorine) and DBPs occurring in water for human consumption and use in the food industry. The study will comprise risk–benefit analyses including quantitative assessments of risk associated with microbial contamination of drinking water versus chemical risk and will compare alternative treatment options. The outcome will be improved risk assessment and better information for risk management. The work is divided into different topics (exposure assessment, epidemiology, risk assessment and management) and studies.
Hexachlorobenzene removal from a model sediment by using ultrasonic irradiation
Authors: Hayashi N. , Liang J. , Choshi H. , Kasai E.
Published: February 2009

Persistent organic pollutants (POPs) are very difficult to degrade when present in the environment and finally accumulate in the human body. Therefore, it is essential to develop efficient technologies for removal of POPs from polluted sediments. In this study, the authors attempted to evaluate the potential of hexachlorobenzene (HCB; a POP) removal by using ultrasonic irradiation and its combination with other advanced chemical oxidation processes (AOPs) and surfactant addition. The average removal ratios for ultrasonic irradiation alone and ultrasonic in combination with UV light irradiation were almost identical at 40%, and the efficiency could be improved to about 49% by combination with photocatalysis or surfactant addition. The dual-frequency ultrasonic irradiation showed the highest HCB removal ratio.
Challenges ahead: social and institutional factors influencing sustainable urban stormwater management in Australia
Authors: Brown R. R. , Farrelly M. A.
Published: February 2009

In a time of climate uncertainty and drought in Australia, improved urban stormwater quality management practices are required not only for protecting waterway health, but also as a fit-for-purpose supply source. To conceive of urban stormwater as an environmental threat as well as a water supply source requires a substantial shift in our traditional linear supply and wastewater structures towards more hybrid and complex infrastructure systems. To understand what drives and limits treatment technology adoption for stormwater management, over 800 urban water professionals in three Australian capital cities completed an online questionnaire survey in November 2006. Using the conceptual framework of receptivity assessment, the results revealed the professional community to be highly associated with the importance of improving stormwater quality for receiving waterway health, yet they do not consider that politicians share this perspective by placing a substantially lower level of importance on stormwater quality management. Significant acquisition barriers within each city, including institutional arrangements, costs, responsibilities, and regulations and approvals processes were all identified as constraining more sustainable practices. Capacity building programs, fostering greater socio-political capital and developing key demonstration projects with training events are recommended as useful policy interventions for addressing current institutional impediments.
Multiphase models for simulating hot and slightly miscible DNAPL (dense non-aqueous phase fluids) in a saturated rock fracture under deformation
Authors: Jha Shibani , Mohan Kumar M. S.
Published: February 2009

In the present study a two dimensional model is first developed to show the behaviour of dense non-aqueous phase liquids (DNAPL) within a rough fracture. To consider the rough fracture, the fracture is imposed with variable apertures along its plane. It is found that DNAPL follows preferential pathways. In next part of the study the above model is further extended for non-isothermal DNAPL flow and DNAPL-water interphase mass transfer phenomenon. These two models are then coupled with joint deformation due to normal stresses. The primary focus of these models is specifically to elucidate the influence of joint alteration due to external stress and fluid pressures on flow driven energy transport and interphase mass transfer. For this, it is assumed that the critical value for joint alteration is associated with external stress and average of water and DNAPL pressures in multiphase system and the temporal and spatial evolution of joint alteration are determined for its further influence on energy transport and miscible phase transfer. The developed model has been studied to show the influence of deformation on DNAPL flow. Further this preliminary study demonstrates the influence of joint deformation on heat transport and phase miscibility via multiphase flow velocities. It is seen that the temperature profile changes and shows higher diffusivity due to deformation and although the interphase miscibility value decreases but the lateral dispersion increases to a considerably higher extent.
Simultaneous determination of 8 fluoroquinolone antibiotics in sewage treatment plants by solid-phase extraction and liquid chromatography with fluorescence detection
Authors: Shi L. , Zhou X. F. , Zhang Y. L. , Gu G. W.
Published: February 2009

Fluoroquinolones (FQs) are among the most important antibiotics used in human and veterinary medicines. A simple and effective analytical method based on reversed-phased liquid chromatography with fluorescence was developed and validated for the simultaneous determination of eight FQs in wastewater at trace level. Aqueous samples were extracted using AnpelTM MEP cartridges where they were subsequently eluted by formic acid in methanol. The aqueous extracts were analyzed by gradient elution Liquid Chromatography with Fluorescence Detection (LC–FLD), whose mobile phase was composed of acetonitrile and 10 mM tetrabutyl ammonium bromide (TBAB). The limits of detection (LOD) and the relative standard deviation (RSD) were as low as 0.11–1.06 μg/L and 2–5%, respectively. The presented method was successfully applied to quantify FQs in the influent and effluent of several typical Sewage Treatment Plants (STPs) in Shanghai. For the extraction of 100 mL influent and 500 mL effluent sewage water samples, recoveries obtained were between 79–109% and 80%–105%, respectively. 7 FQs were occurred and identified in the STPs with the concentrations varying from 7 ng/L to 1 μg/L. Norfloxacin, ciprofloxacin and lomefloxacin were the most frequently detected antibiotics occurring in the wastewaters. The analytical procedure developed may be used for more in-depth studies on the occurrences and the fate of these commonly used pharmaceuticals in the sewage treatment plants and in the aquatic environment.
Modified ferron assay for speciation characterization of hydrolyzed Al(III): a precise k value based judgment
Authors: Changqing Ye , Dongsheng Wang , Xiaohong Wu , Jiuhui Qu , Gregory John
Published: February 2009

The speciation of Al-OH complexes in terms of Ala, Alb and Alc could be achieved by traditional ferron assay and Alb is generally considered as Al13, however, the inherent correlation between them remains an enigma. This paper presents a modified ferron assay to get precise determination of Al13 using nonlinear least squares analysis, and to clarify the correlation between Alb and Al13. Two parallel reactions conforming to pseudo-first-order kinetics can simulate the complicate reactions between polynuclear complexes and ferron successfully. Four types of experimental kinetic constant (k value) of Al-OH complexes can be observed by this method when investigating three typical aluminium solutions. Comparing with the results of 27Al NMR, the species with moderate kinetics around 0.001 s−1 can be confirmed to resemble to Al13 polycation. The other types of kinetics are also well-regulated in partially neutralized aluminium solutions with various OH/Al ratios (b values) in the range 0 ∼ 2.5. It would provide potential means to trace the in-situ formation of Al13 in dilute solutions such as coagulation with Al-based coagulants

Three consulting teams conducted independent modelling projects for three different wastewater treatment plants ranging in size from approximately 113,800 m3/d (30 mgd) to 530,000 m3/d (140 mgd), in different parts of the world (USA and Finland). The plants have different treatment objectives ranging from nitrification and partial denitrification (nitrate plus nitrite <8.7 mg/L) to enhanced nutrient removal (total nitrogen <3 mg/L, total phosphorus <0.3 mg/L). Commonly-used models were applied in the case studies, including ASM3 (using the GPS-X simulator), New General (using GPS-X), Dold (using BioWin), and a variation of the Dold model methanol degradation capabilities (NGmeth within GPS-X). The authors compare and contrast the modelling approaches taken, including calibration and validation approaches, sensitivity analyses, and the application of results to full-scale studies, designs and operations. Despite several differences between the approaches, there are many similarities which are discussed in light of the IWA draft uniform protocol for activated sludge modelling. The authors also discuss current modelling limitations and offer suggestions to improve the state of the art.

Authors: Latimer Ron J. , Pitt Paul , Dold Peter , Takacs Imre , Lynch T. J.
Published: February 2009

The objective of this paper is to identify the importance of kinetic parameters relating to the utilization of nitrite when nitrification and denitrification are modeled as two-step processes. This is an important issue relating to modeling for design and in operation of plants achieving low effluent TN concentrations. A case study using a calibrated model of a full scale plant achieving low effluent TN is used to demonstrate the impacts of key modeling parameters on effluent predictions. The results also demonstrate the importance of full scale plant calibration based on historical data and detailed plant sampling and profiling.
Building ‘learning catchments’ for integrated catchment managing: designing learning systems based on experiences in the UK and South Africa
Authors: Collins Kevin , Colvin John , Ison Ray
Published: February 2009

We examine challenges and opportunities for developing ‘learning systems’ for integrated catchment managing (ICMg) drawing on our experiences in two contexts: UK and South Africa (SA). Our research question is: what is it that we would have to experience to claim that a catchment was a learning catchment? We suggest that any valid answer to this question will arise in social relations in context-determined ways. From this perspective ICMg is an emergent ‘performance’ of stakeholders engaged in mutual action, or social learning (SL), in which understandings and practices are transformed in situation improving ways. These questions are relevant given recent reviews suggesting that implementation of the European Water Framework Directive (WFD) is not nurturing adaptive management. Our European and SA experiences demonstrate that it is possible to invest in social learning as a governance mechanism for water managing, but key constraints exist. Our SA work based on (i) appreciating the situation, especially the history, and (ii) contextual appreciation and design of learning systems (as a result of (i)) is described in response to these constraints. We conclude that more attention on developing an effective praxis for ICMg is required.

Authors: Zivic Ivana , Markovic Z. , Brajkovic Miloje
Published: February 2009

Hydrobiological investigations of the macrozoobenthos were carried out at eight localities in the Toplica river (a right-hand tributary of the Kolubara river) from April 2000 to January 2001. The bottom fauna was composed of 19 groups of macroinvertebrates with 85 determined taxa (61 identified to the species level, 24 to the generic level). The most varying groups were the insect orders Trichoptera (20 taxa), Ephemeroptera (15), and Diptera (13), while Isopoda, Decapoda, and insects belonging to orders Collembola, Heteroptera, Megaloptera, and Planipennia were the most uniform. The species Gammarus pulex fossarum Koch and Dugesia gonocephala Duges were the most abundant forms at the river source, and representatives of Ephemeroptera and Gammaridae were the most numerous in its upper course (at the second, third, and fourth locality). The Mollusca and Chironomidae larvae were the most abundant forms at the fifth locality (in the middle course), but no constant dominance of any animal group was recorded at the sixth one, where the dominance alternated among Chironomidae larvae (April, July 2000), Oligochaeta (October 2000) and Mollusca (January 2001). The lower course of the river (the seventh and eighth locality) was characterized by the dominance of the species of the phylum Mollusca (Amphimelania holandri Ferussac, Fagotia esperi Ferussac and Theodoxus transversalis Pfeiffer).
Microbiological index of water quality (mWQI) tested on the Gruza reservoir
Authors: Curcic Svetlana , Comic Ljiljana
Published: February 2009

The present paper considers formulation of a criterion for estimation of water quality from microbiological parameters (mWQI) based on comparison with WQI using certain elements of fuzzy logic on the example of the Gruza Reservoir. Quantitative estimation of water quality from five important microbiological parameters, the microbiological water quality index (mWQI) is realized using the proposed simple procedure. In view of the fact that the bulk of analyzed water samples belonged to class II, in future investigations the present method will be tested on lakes and reservoirs with a different degree of quality dispersion.
Structure of the macrozoobenthos as an indicator of different types of pollution in running waters
Authors: Simic Vladica , Simic Snezana
Published: February 2009

Hydrobiological research on streams with different dominant forms of pollution (anthropogenic eutrophication, organic pollution, toxic pollution, trans-saprobic pollution) in the central part of the Balkan Peninsula (territory of Serbia and Montenegro) indicates that these different forms of pollution can be detected on the basis of structure of the macrozoobenthos community and individual indicator taxa. It is established from the obtained results that the greatest community diversity occurs in the case of anthropogenic eutrophication or weak organic pollution as a dominant process, where phytophilous and/or detritophagic forms (Cloeon, Polypedilum, Asellus, Stylaria, Erpobdella, Gammarus) are dominant in the community. In the cases of very strong organic pollution, the macrozoobenthos community is characterized by mass development of certain taxa of the group Oligochaeta (Tubificidae) and Chironomidae larvae {Chironomus gr. thummi). Depending on the strength and contribution of organic, toxic, and/or transsaprobic components, toxic pollution and mixed pollution arc characterized by a more or less heterogeneous and nonspecific population. However, a common feature is the presence of a small number of taxa with populations of a relatively low density, or the occurrence of individual specimens belonging to different groups of animals.
New and rare taxa of freshwater zooplankton in the fauna of Yugoslavia
Authors: Ostojic Aleksandar
Published: February 2009

Analysis of the faunistic composition of Zooplankton in two reservoirs for watersupply nearby Kragujevac indicated a relatively great diversity. Qualitative analysis of Zooplankton composition in the Grosnica reservoir demonstrated the presence of 105 laxa, whereas somewhat fewer taxa (99) were recorded in the Gruza reservoir. Most of the taxa recorded in both reservoirs are cosmopolitan organisms. Small number of recorded taxa have been rarely registered in the territory of Serbia till present. The following species from the group of Rotatoria can be mentioned as being probably found for the first time in waters of our country: Dicranophorus rostralus, Philodina aadicomis and Trichocerca jenningsi. All three of these species were recorded only in the Grosnica reservoir. Only inspection of the complete literature on Zooplankton in our country could confirm with certainty that the Grosnica reservoir is the first record of these three species in the territory of Serbia. However, even such data as our represents a contribution to the knowledge on diversity of the Zooplankton fauna of Serbia.

Neuroblastoma (NB) is a malignant childhood solid tumor of neuroectodermal cells. Clinical behavior of neuroblastomas is largely diverse - from spontaneous regression to rapid progression with a fatal outcome. From the analysis of bone marrow and tumors of NB patients at the cytogenetic molecular cytogenetic and molecular level non-random genetic changes have been identified, including ploidy changes, amplification of the N-myc oncogene and deletions of chromosome 1p. In this paper we present the cytogenetic, fluorescence in situ hybridization and molecular findings in 28 Serbian and Montenegrian NB patients. Reliable detection of these features should be regarded as mandatory for all new cases.

Some details on the method for measuring activity changes of neuronal populations
Authors: Kalauzi Aleksandar , Spasic Sladjana , Culic Milka
Published: February 2009

Simple, complex action potentials (AP) and interspike recorded background activity (RBA) were detected and extracted from 12 rat cerebellar cortical recordings. For each recording, an averaged simple action potential (SAP) was formed. Fourier amplitude spectra of SAP and RBA were similar in all recordings. For one of the recordings, a series of RBA simulations (SBA) was generated, superimposing random SAPs, varying the superposition frequency (fsup). Average Fourier amplitude, Amp(SBA), was calculated, in order to use Amp(SBA)=f(fsup) as a calibration line for reading fsup of RBA, which is a measure of the population activity. A probability distribution for SAP intensities was derived and a family of calibration lines constructed. As all lines were linear and parallel (slope S) in log-log plots, a population activity change could be calculated as fsup2/fsup1=[Amp2(RBA)/Amp(RBA)]1/S.

Cloning and computer analysis of the promoter region of the legumin-like storage protein gene from buckwheat, Fagopyrum esculentum Moench
Authors: Milisavljevic Mira , Konstantinovic Miroslav , Brkljacic Jelena , Maksimovic Vesna
Published: February 2009

Using the modified 5?-RACE approach, a fragment containing the 955 bp long 5?- regulatory region of the buckwheat storage globulin gene (FeLEG1) has been amplified from the genomic DNA of buckwheat. The entire fragment was sequenced and the sequence analyzed by computer prediction of cis-regulatory elements possibly involved in tissue specific and developmentally controlled seed storage protein gene expression. The promoter obtained might be interesting not only for fundamental research, but also as a useful tool for biotechnological application.

Between 1997 and 2003, 47 patients with neuroblastoma were treated at the Mother and Child Health Institute of Serbia. The objective of the present study was to determine the relationship between clinical and genetic features and prognosis in neuroblastoma. The 5-year survival rate was best in the age group of less than 1 year (73% vs. 15%; p=0.007) and significantly worse for patients with stage IV than for "non stage IV", patients (13% vs. 47%; p=0.015). The difference in 5-year survival between the 1p deletion positive and 1p deletion negative groups was statistically significant (p=0.008). Overall 5-year survival was significantly worse for patients with N-myc amplification (19% vs. 58%; p=0.014). The difference in the 5-year survival for male and female patients was not statistically significant (p>0.05). Our report demonstrates that N-myc amplification, 1p deletion, stage IV, and age of 1 year and over are factors pointing strongly to an unfavorable outcome in neuroblastoma patients.
A natural hybrid of Leuciscus cephalus and Alburnus alburnus (Pisces, Cyprinidae) from the Ibar River, Western Serbia
Authors: Soric Vitko
Published: February 2009

The hybrid Leuciscus cephalus ? Alburnus alburnus was recognized in studying structure of the ichthyofauna of the middle course of the Ibar River, a right-hand tributary of the Western Morava (system of the Danube on the territory of Serbia). It is a hybrid reciprocal to the natural hybrid Alburnus alburnus ? Leuciscus cephalus from the same river system (the Gruza River, a left-hand tributary of the Western Morava), which was described previously by the present author. The hybrid was identified on the basis of its intermediate characteristics and characteristics of the parent species such as pharyngeal bones and teeth; shape of the scales; number, form, and structure of radial canals of the scales; morphology of branchiospinae on the first gill arch; and a complex of meristic and morphometric characters. With respect to its characteristics, this hybrid, like the hybrid Alburnus alburnus ? Leuciscus cephalus, is closer to L. cephalus. However, in general appearance the hybrid more closely resembles the presumed maternal species. The phenomenon of reciprocal hybridization is discussed at some length.
Effect of ferri(III)citrate and potassium hexacyanoferrate(III) on growth of the moss Bryum argenteum Hedw. (Bryaceae) in vitro
Authors: Vukojevic Vanja , Sabovljevic Aneta , Sabovljevic Marko
Published: February 2009

In order to examine the manner of iron uptake from the medium, in vitro culture of moss Bryum argenteum Hedw. (Bryaceae) was established. Under controlled conditions (16h light/8h dark, light intensity 47?mol m-2s-1 25?2?C), the moss was grown on basal MS medium or on MS medium enriched with various concentrations of ferri(III)citrate or potassium hexacyanoferrate(III). It was expected that with the organic chelate complex, Fe(III) ion will be more available for the plant. Sixty days after establishing in vitro culture, the plants grown on MS medium enriched with the ferri(III)citrate complex were developed better than plants grown on media with the potassium hexacyanoferrate(III) complex. To judge from plant production in vitro and in view of the fact that the two compounds were the only source of Fe(III), it would appear that the citrate complex makes Fe(III) ions more available than potassium hexacyanoferrate(III). Further research will examine the concentrations of Fe ion uptake by plants and potential use of these tiny moss plants for the phytomining, phytoremedies and hyperaccumulating purposes.

Life strategies of bryophytes on loess cliffs in Vojvodina, Serbia
Authors: Sabovljevic Marko
Published: February 2009

The loess cliffs of Vojvodina present a special ecosystem type. The main plant components in these habitats are cryptogams (bryophytes and lichens). The biology and life strategies of bryophytes recorded on loess in Vojvodina are studied in the present work, whose results confirm a very special ecology in such habitats. Colonist species with xeropottioid characteristics are dominant among bryophytes. It is stressed that loess cliff habitats are especially important from the standpoint of conservation.
Using of epiphytic lichens for bioindication of air pollution in Vranje
Authors: Stamenkovic S. , Cvijan Mirko
Published: February 2009

Epiphytic lichens were used dor bioindication of air pollution in the city of Vranje for the first time. In 43 investigated places, the authors established the presence of 38 lichen taxa from 20 genera. By calculating the index of atmospheric purity (IAP), they established three zones with different air pollution levels (a "lichen desert zone", a "transitional zone", and a "normal zone") and two subzones (a "narrow transitional zone", and a "wider transitional zone"). The species Melanelia exasperatula, M. glabra, Lecanora allophana, Lecidella elaechroma, Ochrolechia sp, Ramalina sp., and Parmelina quercina were established as the most sensitive. On the other hand, Phaeophyscia orbicularis, Xanthoria parietina, and Parmelia sulcata were the most tolerant.

Mosses accumulate heavy metals from the substrata of coal ash
Authors: Vukojevic Vanja , Sabovljevic Marko , Jovanovic S.
Published: February 2009

Plants that are able to accumulate and tolerate extraordinarily high concentrations of heavy metals (hyperaccumulators) can be used for phytoremediation (removal of contaminants from soils) or phytomining (growing a crop of plants to harvest the metals). Two moss species, Bryum capillare Hedw. and Ceratodon purpureus Hedw., were tested as potential phytoremedies under in vivo conditions on a coal ash disposal site in the surroundings of Obrenovac (NW Serbia). The content of various heavy metals (iron, manganese zinc, lead, nickel, cadmium, and copper) in the mosses and substrata were investigated over a period of three years. Iron and zinc were found to have the highest concentration in the mosses.
Some rare longhorn beetles (Coleopterta: Cerambycidae) without protection on the national level found on Mt. Fruska Gora, Serbia
Authors: Pil Natasa , Stojanovic D.
Published: February 2009

Entomological research and literature data on longhorn beetles (Coleoptera Cerambycidae) indicate the presence of 78 species on the mountain Fruska Gora, Serbia. Nineteen species are listed as rare on the territory of Serbia and Montenegro. Based on information about their bionomy and general distribution, these species are divided into five groups: a group of species with narrow ranges; a group of species whose range border passes through the territory of Serbia and Montenegro; a group of species which develop on only a few botanical species; a group of species for which the territory of Serbia and Montenegro is not their range border, but which are found rarely; and species introduced to Europe.
Antimutagenic effect of essential oil of sage (Salvia officinalis L.) and its fractions against UV-induced mutations in bacterial and yeast cells
Authors: Knezevic-Vukcevic Jelena , Vukovic-Gacic Branka , Stevic Tatjana , Stanojevic Jasna , Nikolic Biljana , Simic Draga
Published: February 2009

The inhibition of spontaneous and UV-induced mutations by essential oil (EO) of sage (Salvia officinalis L.) and its fractions F1-F5 containing different proportions of mono- and sesquiterpenes was studied with the Salmonella/microsome, E. coli K12, and S. cerevisiae D7 reversion assays. The EO, F1, and F2 exhibited antimutagenic potential against UV-induced mutations in all tests. Fractions F3 and F4 produced a toxic, mutagenic, or antimutagenic response, depend?ing on the test organism used. Reduction of spontaneous and UV-induced mutations by F5 was detected only in permeable strains of E. coli. The obtained results demonstrate antimutagenic activity of volatile sage terpenes and recommend them for further antimutagenesis and anticarcinogenesis studies.
