Published: August 2012

Deep-Water Benthic Polychaetes (Vigtorniella ZaikaiandProtodrilussp.) in the Black Sea as Indicators of the Hydrogen Sulfide Zone BoundaryThe Black Sea hypoxic layer, situated near the boundary of the hydrogen sulfide zone, is inhabited by the polychaetesVigtorniella zaikai, Kisseleva, 1992 andProtodrilussp., which can serve as indicators of the interface between oxic and anoxic water. The maximum number of polychaetes in the northern part of the Black Sea occur at a depth of 150 m, while near Bosporus, where the flow of the Marmara Sea water enters the Black Sea, the peak depth varies from 150 to 250 m.

Biotopic Distribution of Naked Amoebas (Protista) in Ukrainian Polissya Area
Forty-one species of naked amoebas were found in the different types of waterbodies of Zhytomyr and Volyn' parts of Ukrainian Polissya region. The major part of species of naked amoebas in this region demonstrated the prevalence to living in a certain type of water body that possible depends on the hydrochemical and trophic parameters of water. The limnetic and floodplain species complexes of amoebas are distinguished in Ukrainian Polissya.

Distribution of the TickHaemaphysalis Punctata(Acari, Ixodidae) in UkraineThe northern boundary ofH. punctatarange was studied. This boundary of its native range (where this species is common and its mass reproductions are periodically recorded) was found to go through Odesa, Mykolaiv, Kherson, Zaporizhia, Donetsk and Lugansk oblasts. Clarified that the boundary of its temporary range (where this species occurs periodically and is dependent on human factors totally) was clarified to go through Volyn, Rivne, Zhytomyr, Kyiv, Chernihiv and Sumy regions. The range of H. punctata is fully subjected to anthropogenic factors in areas where this species dwelt in historically recent times only, and in ancestral areas of distribution such factors affects only dynamics and indices of abundance.

A Multi-Model Assessment of Climate Change Impact on Hydrological Regime in the Czech RepublicIn present paper we assess the climate change impact on mean runoff between the periods 1961-1990 (control period) and 2070-2099 (scenario period) in the Czech Republic. Hydrological balance is modelled with a conceptual hydrological model BILAN at 250 catchments of different sizes and climatic conditions. Climate change scenarios are derived using simple delta approach, i.e. observed series of precipitation, temperature and relative air humidity are perturbed in order to give the same changes between the control and scenario period as in the ensemble of 15 transient regional climate model (RCM) simulations. The parameters of the hydrological model are for each catchment estimated using observed data. These parameters are subsequently used to derive discharge series under climate change conditions for each RCM simulation. Although the differences in the absolute values of the changes in runoff are considerable, robust patterns of changes can be identified. The majority of the scenarios project an increase in winter runoff in the northern part of the Czech Republic, especially at catchments with high elevation. The scenarios also agree on a decrease in spring and summer runoff in most of the catchments.
Fuzzy Model Used for the Prediction of a State of Emergency for a River Basin in the Case of a Flash Flood - PART 2

Fuzzy Model Used for the Prediction of a State of Emergency for a River Basin in the Case of a Flash Flood - PART 2This article is a continuation of a previous one named Fuzzy model use for prediction of the state of emergency of river basin in the case of flash flood (Janál&Starý, 2009), where the potential applications of fuzzy logic in the field of flash flood forecasting were described. Flash flood forecasting needs a specific approach because of the character of torrential rainfall. Storms are very difficult to forecast in space and time. The hydrological models designed for flash flood prediction have to be able to work with very uncertain input data. Moreover, the models have to be capable of evaluating the level of danger in as short a time as possible because of the highly dynamic character of the modeled process. The fuzzy model described in the previous article was modified into a form usable in operational hydrology and a simulation of its operational application was run using this model. The selected time period for the simulation was the summer of 2009, when numerous flash floods occurred in Czech Republic. The topic of this article is the preparation of the model for practical use and the results of the simulation of its operation.
The Influence of Current on the Height of Wind Wave Run-Up: A comparison of experimental results with the Czech National Standard

The Influence of Current on the Height of Wind Wave Run-Up: A comparison of experimental results with the Czech National StandardOne of the basic questions related to the safety of dikes and river levees is the size of the freeboard. One of the important parameters for freeboard design is the height of waves and wave run-up on levee slopes. Routine and standardised calculations of wave run-up deal with the freeboards of dams where wind waves originate on the still water of the reservoir. In the case of running water in streams (thereinafter only "currents") the effect of wave and current interaction on wave run-up is usually not taken into account due to the lack of reliable knowledge regarding the phenomenon. In the Czech Republic this question is topical in the case of large rivers such as the Elbe, the Vltava and the Morava. Within the framework of the projects Hydralab III and NAZV QI 92A139, hydraulic research and further analysis focused on wave run-up as a result of the combination of current and wind wave parameters were performed. The laboratory research was carried out in a hydraulic flume with a wavemaker on the right bank and a levee with a slope of 1:3 installed on the left bank opposite the wavemaker. Waves were generated both perpendicular and oblique to the levee axis; the angle of oblique wave attack varied within the range of ± 30°. The aim of this paper is to compare the results of the mentioned research with recommendations mentioned in the Czech National Standard CSN 75 0255Calculation of wave effects on water structuresand to quantify the effect of current on the wave run-up height.

Uncertainty Analysis of a Dual-Continuum Model Used to Simulate Subsurface Hillslope Runoff Involving Oxygen-18 as Natural TracerA one-dimensional dual-continuum model (also known as dual-permeability model) was used to simulate the lateral component of subsurface runoff and variations in the natural18O content in hillslope discharge. Model predictions were analyzed using the GLUE generalized likelihood uncertainty estimation procedure. Model sensitivity was evaluated by varying two separate triplets of parameters. The first triplet consisted of key parameters determining the preferential flow regime, i.e., the volumetric proportion of the preferential flow domain, a first-order transfer coefficient characterizing soil water exchange between the two flow domains of the dual-continuum system, and the saturated hydraulic conductivity of the preferential flow domain. The second triplet involved parameters controlling exclusively the soil hydraulic properties of the preferential flow domain, i.e., its retention curve and hydraulic conductivity function. Results of the analysis suggest high sensitivity to all parameters of the first triplet, and large differences in sensitivity to the parameters of the second triplet. The sensitivity analysis also confirmed a significant improvement in the identifiability of preferential flow parameters when18O content was added to the objective function.

Estimating Flash Flood Peak Discharge in Gidra and Parná Basin: Case Study for the 7-8 June 2011 FloodWe analyzed the runoff and its temporal distribution during the catastrophic flood events on river Gidra (32.9 km2) and Parná (37.86 km2) of the 7th June 2011. The catchments are located in the Small Carpathian Mountains, western Slovakia. Direct measurements and evaluation of the peak discharge values after such extreme events are emphasized in the paper including exceedance probabilities of peak flows and of their causal flash rainfall events. In the second part of the paper, plausible modeling mode is presented, using the NLC (Non Linear Cascade) rainfall-runoff model. Several hypothetical extreme flood events were simulated by the NLC model for both rivers. Also the flood runoff volumes are evaluated as basic information on the natural or artificial catchment storage.
Solutions to the ellipsoidal Clairaut constant and the inverse geodetic problem by numerical integration
Authors: Sjöberg L. E. 
Published: August 2012

AbstractWe derive computational formulas for determining the Clairaut constant, i.e. the cosine of the maximum latitude of the geodesic arc, from two given points on the oblate ellipsoid of revolution. In all cases the Clairaut constant is unique. The inverse geodetic problem on the ellipsoid is to determine the geodesic arc between and the azimuths of the arc at the given points. We present the solution for the fixed Clairaut constant. If the given points are not(nearly) antipodal, each azimuth and location of the geodesic is unique, while for the fixed points in the ”antipodal region”, roughly within 36”.2 from the antipode, there are two geodesics mirrored in the equator and with complementary azimuths at each point. In the special case with the given points located at the poles of the ellipsoid, all meridians are geodesics. The special role played by the Clairaut constant and the numerical integration make this method different from others available in the literature.
Determination of sea surface height from moving ships with dynamic corrections
Authors: Reinking J. , Härting A. , Bastos L. 
Published: August 2012

AbstractWith the growing global efforts to estimate the influence of civilization on the climate change it would be desirable to survey sea surface heights (SSH) not only by remote sensing techniques like satellite altimetry or (GNSS) Global Navigation Satellite System reflectometry but also by direct and in-situ measurements in the open ocean. In recent years different groups attempted to determine SSH by ship-based GNSS observations. Due to recent advances in kinematic GNSS (PPP) Precise Point Positioning analysis it is already possible to derive GNSS antenna heights with a quality of a few centimeters. Therefore it is foreseeable that this technique will be used more intensively in the future, with obvious advantages in sea positioning. For the determination of actual SSH from GNSS-derived antenna heights aboard seagoing vessels some essential hydrostatic and hydrodynamic corrections must be considered in addition to ocean dynamics and related corrections. Systematic influences of ship dynamics were intensively analyzed and sophisticated techniques were developed at the Jade University during the last decades to precisely estimate mandatory corrections. In this paper we will describe the required analyses and demonstrate their application by presenting a case study from an experiment on a cruise vessel carried out in March 2011 in the Atlantic Ocean.

High agreement of routine cytopathology and immunocytochemistry in canine lymphomas
The aim of this study was to compare the concordance of immunophenotype established with routine cytopathology (slides stained with Giemsa solution) and immunocytochemistry according to CD3 and CD79 alpha immunoreactivity. The study was performed on cytological samples of 70 canine lymphomas subtyped on the basis of the updated Kiel classification system. Additionally, cytologic samples were examined immunocytochemically for the CD3 and CD79 alpha antigens presence and thus immunophenotype of neoplastic growth was confirmed. The cytopathological and immunocytochemical diagnoses were then compared; in order to measure the concordance between immunocytochemistry (IC) result and Giemsa stain result of the same sample the Cohen's kappa coefficient was calculated. On the basis of the results of immunocytochemistry of 70 cases of canine lymphoma examined 42 were recognized as B cell lymphoma and 28 as T cell lymphoma. Full accordance between the results of routine cytopathology and IC was obtained in 63 out of 70 examined dogs (90% of cases). It can be concluded that cytopathological examination of Giemsa stained smears is helpful in determining the lymphoma cells immunophenotype. Additionally, it seems that combination of routine cytopathology and immunocytochemistry in cases of canine lymphomas allows to obtain the precise diagnosis in 90% of cases, and allows to receive most important information that is necessary for planning of appropriate therapy and to determine prognosis. Finally, this routine procedure allowed to eliminate the need of collection of tissue samples during surgery or core-biopsy and thus time, cost and patient discomfort related to more complex and invasive medical procedures can be easily reduced.

Concentration of serum amyloid A and ceruloplasmin activity in milk from cows with subclinical mastitis caused by different pathogensThe aim of the present study was to determine the concentration of serum amyloid A (SAA) and the activity of ceruloplasmin (Cp) in milk from cows with subclinical mastitis caused by different pathogens. Eighty-four milk samples from cows with subclinical mastitis and fourteen milk samples from healthy cows were examined. SAA concentration was determined using the commercial ELISA kit (Tridelta Development Ltd., Greystones, Wicklow, Ireland). Cp activity was assessed spectrophotometrically, using the Rice method. The results reveal that the concentration of SAA (with exception of CNS) and activity of Cp in cow milk can be regarded as markers of subclinical mastitis, irrespective of the microorganism inducing the disease. In conclusion, measurement of SAA and Cp in milk samples could be a useful method in diagnosing subclinical mastitis in cows, but the method should be adapted for field use.

Avian influenza viruses in wild birds at the Jeziorsko reservoir in Poland in 2008-2010
During a 3-year surveillance study for avian influenza virus (AIV) infections at the Jeziorsko reservoir in central Poland, 549 oropharyngeal or cloacal swabs from 366 birds of 14 species belonging to 3 orders (Anseriformes, Charadriiformes and Gruiformes) were tested. AIV was detected in 14 birds (3.8%): Common Teals (12x), Mallard (1x) and Garganey (1x). Three potentially dangerous H5 AIV were detected in Common Teals (2x) and Garganey (1x) but all of them revealed a low pathogenic pathotype. A unique cleavage site amino acid motif PQREIR*GLF was found in one H5 isolate from a Garganey.

Botulinum toxin type A-induced changes in the chemical coding of dorsal root ganglion neurons supplying the porcine urinary bladder
Botulinum toxin type A (BTX) is a potent neurotoxin, which in recent years has been effectively applied in experimental treatments of many neurogenic disorders of the urinary bladder. BTX is a selective, presynaptically-acting blocking agent of acetylcholine release from nerve terminals what, in turn, leads to the cessation of somatic motor and/or parasympathetic transmission. However, application of this toxin in urological practice is still in the developmental stages and the full mechanism of its action remain elusive. Thus, the present study was aimed at investigating the neurochemical characterization of dorsal root ganglion (DRG) neurons supplying the porcine urinary bladder after BTX treatment. Retrograde tracer Fast Blue (FB) was injected into the urinary bladder wall in six juvenile female pigs and three weeks later, intramural bladder injections of BTX (100 IU per animal) were carried out in all the animals. After a week, DRG from L1 to Cq1 were harvested from the pigs and neurochemical characterization of FB+ neurons was performed using double-labeling immunofluorescence technique on 10-μm-thick cryostat sections. BTX injections led to a significant decrease in the number of FB+ neurons containing substance P (SP), calcitonin gene-related peptide (CGRP), calbindin (CB), somatostatin (SOM) and neuronal nitric oxide synthase (nNOS) when compared with that found in the healthy animals (19% vs. 45%, 18% vs. 36%, 0.6% vs. 3%, 0.4 vs. 4% and 0.1% vs. 6%, respectively) These data demonstrated that BTX changed the chemical coding of bladder sensory neurons, and therefore this drug should be taken into consideration when it planning experimental therapy of selected neurogenic bladder disorders.

Zearalenone and deoxynivalenol mycotoxicosis in dairy cattle herds
Mycotoxin contaminations pose a growing problem in animal production from the economic and toxicological point of view. Clinical symptoms of mycotoxicosis are relatively unspecific, making the disease difficult to diagnose. This study presents a clinical case of dairy cattle infected with natural mycotoxins produced by fungi of the genus Fusarium (zearalenone [ZEA] and deoxynivalenol [DON]) in eastern Poland. In dead and infected cows, the presence of ZEA and DON was determined in the blood serum, significant changes were observed in blood morphological and biochemical profiles, extravasations and bowel inflammations were also observed. The results reported testify to an acute autoimmune process in the intestines as well as immunosuppression.

Comparison of the influence of EDTA-K3 and sodium citrate on haematology analysis in healthy dogs
The study was carried out on 30 clinically healthy dogs of various breeds. Haemoglobin concentration, haematocrit, platelet count and platelet haematocrit were significantly lower in citrate blood than in tripotassium ethylenediaminetetraacetic acid (EDTA-K3) blood. The study confirmed the limited usage of sodium citrate in haematology analysis, unless canine EDTA-dependent thrombocytopenia is suspected.
Cost-of-alcohol studies as a research programme
Authors: Mäkelä Klaus 
Published: August 2012

Aims According to the literature, estimates of the costs of alcohol abuse serve four main purposes: They draw attention to the severity of alcohol problems, they help to target specific problems and policies, they identify information gaps and they provide a baseline for future cost-effectiveness studies. This paper evaluates to which extent these purposes have been met in recent studies and how likely they can be met in the future. Method Critical review. Material Thirty reports on alcohol costs published after 2000. Conclusions Even the most sophisticated cost-of-alcohol calculations include entries based on misleading assumptions or logical mistakes. Monetary calculations do not add precision to the comparison of the weight of health problems. Cost calculations cannot be used to compare the extent or nature of alcohol problems in different countries. Cost calculations should focus on money spent from clearly defined budgets. Calculating the costs to “society” is not a promising research program. It is good to measure the joys and sorrows of heavy drinkers and their nearest, but the use of a monetary metric conceals important issues and value judgments. As a research program, the cost-of-alcohol tradition is based on promises about future cost-effectiveness studies, but traditional measures of alcohol problems offer a better picture of the effects of policy measures than cost-of-alcohol estimates.
Prevalence and perceptions of ketamine use among Danish clubbers: A mixed-method study
Authors: Ravn Signe , Demant Jakob 
Published: August 2012

Aims This article describes the prevalence of ketamine use among Danish recreational drug users and provides a contextual understanding of ketamine use within this group. Methods and Data The analysis is based on a mixed-methods night club study combining a survey among guests in night clubs (N=1,632) with qualitative interviews (9 focus group interviews, 6 double interviews, 7 individual interviews; 53 clubbers in total). Results 10% of the clubbers have tried ketamine (lifetime use). The ketamine users have also tried a range of other drugs. When taken in club settings, ketamine is often part of a polydrug repertoire. When used in private settings, ketamine is often taken alone to explore its hallucinogenic effects. The users are aware of the potency of the drug, but do not pay attention to long-term negative effects of ketamine use. Conclusion Ketamine users predominantly prefer to use ketamine in private settings. This can be viewed as a strategy for risk management, but also as a way of optimising the combination of drug – place – social – body, thereby creating a drug experience that is not possible in public settings.
