Published: June 2016

Zusammenfassung
Dieser Beitrag betrachtet den Entwurf von Gleitzustandsreglern für hydraulische Wegeventile. Ausgehend von der Motivation,
die Komplexität der gegenwärtig verwendeten Regler zu reduzieren, wird ein Ansatz basierend auf der Gleitzustandsregelung
zweiter Ordnung diskutiert. Typischerweise erfolgt die Parametrisierung der Regler im Kontext hydraulischer Systeme durch
Evolutionäre Optimierungen, die eine Vielzahl von zeitaufwändigen Experimenten am realen System durchführen. Dieser
Beitrag verfolgt ein simulationsgestütztes Vorgehen. Für das hydraulische Wegeventil wird ein physikalisch motiviertes
Streckenmodell vorgestellt, anhand dessen in der Simulation die Regler parametrisiert werden. Der Vergleich zwischen den
simulierten und real gemessenen Sprungantworten zeigt eine hohe Übereinstimmung und ein Verlust an Regelgüte ist beim
Übergang von der Simulation zum realen System nicht erkennbar. Im Vergleich zu anderen Verfahren kann somit gezeigt
werden, dass durch Verwendung von Simulationsmodellen für Wegeventile die Inbetriebnahmezeiten deutlich reduziert werden
können.

Published: June 2016

Zusammenfassung
Die Erstellung des Markovmodells einer komplexen Sicherheitseinrichtung unter Berücksichtigung von
Instandhaltungsmaßnahmen zu festgelegten Zeitpunkten ist komplex und schränkt den möglichen Detailierungsgrad
ein. Probabilistische Boolesche Netzwerke (PBN) werden als kompakte lineare Darstellung für stochastische Automaten mit
deterministischen Übergängen eingeführt. Für diese wird dann eine neue Methode entwickelt, mit welcher das Modell eines
komplexen Systems mit einfachen Eingaben automatisch erstellt werden kann.
On the Rejectability of the Subjective Expected Utility Theory
Authors: Grabiszewski Konrad 
Published: June 2016

AbstractState space, a key element of the Subjective Expected Utility (SEU) theory, is not observable. This implies that, in order to test the SEU theory, it is necessary to assume some state space. Consequently, if the SEU theory is rejected, then it is appropriate to conduct a robustness check; that is, to search for a different state space and a probability over that state space which together do not lead to the rejection of the SEU theory. To find such state space and probability means to SEU-rationalize the agent’s behavior. I show how to conduct the process of SEU-rationalization and determine when an SEU-rationalization is possible.
Two rare halophyte species: Aster tripolium L. and Plantago maritima L. on the Baltic coast in Poland – their resources, distribution and implications for conservation management
Authors: Lazarus Magdalena , Wszałek-Rożek Katarzyna 
Published: June 2016

Abstract
The paper presents the results of geobotanical studies on the distribution and resources of Aster tripolium L. and Plantago maritima L, two rare halophytes in Poland. The research was conducted in northern Poland, along the Baltic coast in 2013. The present distribution of the two species was compared with historical data and general trends of and threats to these two species were examined. In total, 33 sites of A. tripolium and 18 of P. maritima were found in the research area. The resources of both species have been perceptibly depleting during last 150 years, which is mostly due to human agencies (e.g. habitat devastation caused by growing urban areas and the change in management and/or habitat condition). In order to preserve both species, it may be necessary to start an ex situ conservation program.
Evaluation of Control Strategies in Activated Sludge Process for Biological Wastewater Treatment
Authors: Vivekanandan B. , Seshagiri Rao A. 
Published: June 2016

Abstract
In this paper, benchmark simulation model no.1 (BSM1) of an activated sludge process is used to evaluate various control strategies. Control configurations such as feedback control and feed-forward plus feedback (FF-FB) control are applied and compared with respect to effluent discharge requirements under specified constraints and operating costs. Feed-forward control is incorporated in the PI control configuration for preventing the influent loading disturbance affecting the process. No case studies of BSM1 model have been reported in the literature for the Indian wastewater. In this work, the dynamic simulation of an activated sludge process is performed using the data collected from the sewage treatment plant, located in India. The influent load data are collected during the dry weather period. The influent fractionation is carried out using the activated sludge model no.1 (ASM1). The results of the dynamic simulation indicate that FF-FB control of the activated sludge process is more effective than feedback control in meeting the constraints, especially effluent ammonia concentration which is considered as very important. From the comparison of performance evaluation criteria, it is observed that FF-FB control has achieved almost the same operating costs as with feedback control.

Abstract
Mupirocin is an antibiotic having a unique mode of action, not shared by any other therapeutically available antibiotic. However, due to its rapid elimination following injection and high protein binding, current therapeutic use is limited to topical administration. Computational methods have identified mupirocin as a good candidate for delivery via long-circulating nano-liposomes. Formulating mupirocin in such liposomes to form Nano-mupirocin protects the drug in the circulation, enabling therapeutic efficacy. This was demonstrated using two different animal models that served as a proof of concept: the mice necrotizing fasciitis and rabbit endocarditis models. In both animal models, mupirocin administered intravenously (IV) lacked therapeutic efficacy, while the Nano-mupirocin administered IV was efficacious. In both mice and rabbits the pharmacokinetic (PK) profile following IV injection of Nano-mupirocin showed significantly greater AUC and elimination half-life of Nano-mupirocin compared to the free drug. In addition, in mice we also demonstrated significant drug distribution into the disease site. These PK profiles may explain Nano-mupirocin’s superior therapeutic efficacy. To the best of our knowledge, this is the first study demonstrating that systemic activity of mupirocin is feasible. Therefore, Nano-mupirocin can be considered a novel and unique parenteral antibiotic candidate drug.
Projected effects of climate change on the carbon stocks of European beech (Fagus sylvatica L.) forests in Zala County, Hungary
Authors: Somogyi Zoltán 
Published: June 2016

Abstract
Recent studies suggest that climate change will lead to the local extinction of many tree species from large areas during this century, affecting the functioning and ecosystem services of many forests. This study reports on projected carbon losses due to the assumed local climate change-driven extinction of European beech (Fagus sylvatica L.) from Zala County, South-Western Hungary, where the species grows at the xeric limit of its distribution. The losses were calculated as a difference between carbon stocks in climate change scenarios assuming an exponentially increasing forest decline over time, and those in a baseline scenario assuming no climate change. In the climate change scenarios, three different sets of forest management adaptation measures were studied: (1) only harvesting damaged stands, (2) additionally salvaging dead trees that died due to climate change, and (3) replacing, at an increasing rate over time, beech with sessile oak (Quercus petraea Matt. Lieb.) after final harvest. Projections were made using the open access carbon accounting model CASMOFOR based on modeling or assuming effects of climate change on mortality, tree growth, root-to-shoot ratio and decomposition rates. Results demonstrate that, if beech disappears from the region as projected by the end of the century, over 80% of above-ground biomass carbon, and over 60% of the carbon stocks of all pools (excluding soils) of the forests will be lost by 2100. Such emission rates on large areas may have a discernible positive feedback on climate change, and can only partially be offset by the forest management adaptation measures.
Test of airborne laser scanning ability to refine and streamline growing stock estimations by yield tables in different stand structures
Authors: Kulla Ladislav , Sačkov Ivan , Juriš Miroslav 
Published: June 2016

Abstract
Even if stand inventories based on growth tables have been widely discussed over the last years, this method of forest mensuration is still widely applied due to favourable ratio between costs and achievable precision of stand growing stock estimation. The aim of the study was to verify the potential of airborne laser scanning data (ALS) for direct estimation of mean stand height and mean stand density (stocking) as fundamental inputs for forest mensuration based on yield tables. The material from two reference plots with substantially different stand structure was processed by REFLEX software, and confronted with the results of the precise terrestrial inventory. The number of detected tree tops decreased from 100% in the case of super-dominant trees to 30% and 5% in the case of supressed trees at the homogeneous and heterogeneous plot, respectively. The correlation of ALS heights with terrestrially measured heights was R = 0.88 at the homogenous plot, and R = 0.77 at the heterogeneous plot. The tendency to underestimate dominant and to overestimate suppressed trees was revealed at both plots, but was more pronounced at the heterogeneous one. Nevertheless we justified that the mean ALS height calculated from the heights of the detected trees represented the biometric mean stand height linked to the stem with the mean basal area quite well. The stocking estimated by REFLEX software according to delineated crowns´ area was also closer to the real value of stocking than the one obtained by the routine mensuration procedure. The results indicate promising potential of the ALS data processed by REFLEX software to rationalise forest mensuration based on yield tables in even-aged forest structures.

Abstract
A convenient synthesis of 1,3,4-oxadiazole containing derivatives of chromeno[4,3-b]pyridine (6a–e, 8a–e and 9a–e) starting from 4-hydroxycoumarin is presented. The synthesized compounds were screened for in vitro antimicrobial activity against representative bacterial and fungal species. The MIC (minimum inhibitory concentration) of the synthesized compounds ranges between 5 and 15 μg/mL, which is comparable with MIC of standard drugs. Compounds 6c, 8c–e, 9c and 9e have the highest potency for certain bacteria and fungi.

Published: June 2016

Abstract
Hygienic behaviour is a complex trait that gives Apis mellifera L. resistance against brood diseases. Variability in the expression of hygienic behaviour is evidenced at the colony-level and is explained by the proportion and propensity of individual worker bees that engage in hygienic activities. We investigated the temporal performance and the dynamics of task-specialisation of individual bees over time, both in selected hygienic (H) and non-hygienic (NH) colonies. Then we evaluated the impact of these behavioural aspects on the colony performance. Bees that perform hygienic behaviour (hygienic bees) in our H colonies were more persistent in the hygienic activities throughout the days of the investigation. Such bees were more efficient in the removal of pin-killed brood than hygienic bees in the NH colonies. Hygienic bees in the H colonies were also specialist in the sub-tasks involved in the detection of odour stimulus from dead brood and continued to perform these activities throughout the days of the investigation (temporal persistence). Age-distribution of hygienic bees in the H colonies was asymmetrical, with a larger proportion of these bees performing hygienic activities early in life. At a colony-level, H showed higher efficiency compared to the NH colonies. The present results highlight the fact that individual behaviour may influence the collective dynamics of the hygienic behaviour in honeybee colonies. The results also note that the selection for highly hygienic colonies would result in changes in individual bees that improve the performance of the behaviour at the colony level. The relevance of task-partitioning and age-specialisation of hygienic bees on social immunity is discussed.

Published: June 2016

Abstract
The presence of nanoparticles on the body of the honeybee Apis dorsata Fabricius, was investigated for the first time to better understand the bee’s behaviour. These have been observed by using Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM) and confirmed by Atomic Force Microscopy (AFM). Our study clearly denotes that the Indian rock honey bee Apis dorsata possess calcium silicate and calcium phosphate nanoparticles on its body surface of 5-50 nm in diameter. In particular, the nanoparticles on the abdomen and thorax of A. dorsata have an average diameter of about 10 nanometers and they are smaller than those found on wings of the same bees which are about 20 nanometers. The nanoparticles found are different of the ones previously observed on honey bees or other insects. The origin and role of these natural nanoparticles on the body of the Indian rock bee need to be to be further investigated; more research in the subject might raise important aspects in relation to the conservation of these unique pollinators.
Phylogenetic analysis of the honeybee Sacbrood virus
Authors: Li You , Zeng Zhi Jiang , Wang Zi Long 
Published: June 2016

Abstract
Sacbrood virus (SBV) is one of the most common and harmful viruses to honeybees. It causes failure to pupate and death during larval stage, in adult bees it has an influence on their behavior and even shortens their life-span. In this study, we analyzed the phylogenetic relationships among the SBV isolates from all around the world, with from both Apis cerana and Apis mellifera. Phylogenetic trees were constructed based on three types of nucleotide sequences: complete genome sequence, VP1 gene and SB1-2 fragment of SBV. Moreover, genome recombination analysis was performed to assess the effect of genome recombination on the evolutionary relationship of some SBV isolates. The phylogenetic trees showed that although all the SBV isolates form two major groups, these two groups were not formed strictly according to their host specificity or geographical origin. These results indicate that both host specificity and geographic origin decide the genetic diversity of SBV strains.
The antioxidant defense system of Varroa destructor mites facilitates the infestation of Apis mellifera

Published: June 2016

Abstract
Varroa destructor is a parasitic mite of the Western honey bee. The activity of five antioxidant enzymes of V. destructor were analysed. Glutathione content and total antioxidant status was also evaluated. Our results suggest that antioxidant enzymes constitute the main line of defense against ROS in V. destructor, whereas low-molecular-weight antioxidants play a limited role in the antioxidant system of mites.

Abstract
Introduction: The prognostic value of epicardial fat thickness (EFT) and inflammatory biomarkers such as hs-CRP have not been fully investigated in patients with acute myocardial infarction (AMI) and type 2 diabetes mellitus (DM). The study aim was to assess the correlation between the EFT, the persistence of elevated circulating levels of hs-CRP at 7 ± 2 days after an AMI and the amplitude of the left ventricular (LV) remodeling, in patients with type 2 DM. Methods: The study included 98 patients (45 with type 2 DM and 43 with no DM): Group 1 included 22 low-to-intermediate risk patients (hsCRP <3 mg/l) and Group 2 had 23 high-risk, (hsCRP >3 mg/l) patients. EFT, LV function and remodeling were assessed at baseline and at six months after AMI in both groups. Results: In the diabetic population, the EFT was significantly higher in patients who developed ventricular remodeling as compared with those who did not (8.02 ± 1.80 mm vs. 6.65 ± 2.17 mm, p = 0.02) and significantly correlated with the circulating levels of hs-CRP (r = 0.6251, p <0.0001). The levels of circulating hs-CRP, at baseline, significantly correlated with the RI at six months (r = 0.39, p <0.001). Also, in the diabetic population, the epicardial fat thickness was significantly higher in patients who developed ventricular remodeling as compared with those who did not (8.02 ± 1.80 mm vs. 6.65 ± 2.17 mm, p = 0.02). The epicardial adipose tissue thickness significantly correlated with the circulating levels of hs-CRP (r = 0.6251, p <0.0001), while in the non-diabetic population, EFT was not significantly higher in patients who developed ventricular remodeling as compared with those who did not (71.38 ± 9.09 vs. 67.4 ± 10.17, p = 0.23). Multivariate analysis identified the hs-CRP values (OR: 4.09, p = 0.03) and the EFT (OR: 6.11, p = 0.01) as significant independent predictors for LV remodeling in diabetic population. Conclusions: A larger EFT is associated with a more severe remodeling and impairment of ventricular function in patients with type 2 DM and AMI.
Götterdämmerung over total least squares
Authors: Malissiovas G. , Neitzel F. , Petrovic S. 
Published: June 2016

Abstract
The traditional way of solving non-linear least
squares (LS) problems in Geodesy includes a linearization
of the functional model and iterative solution of a nonlinear
equation system. Direct solutions for a class of nonlinear
adjustment problems have been presented by the
mathematical community since the 1980s, based on total
least squares (TLS) algorithms and involving the use of singular
value decomposition (SVD). However, direct LS solutions
for this class of problems have been developed in
the past also by geodesists. In this contributionwe attempt
to establish a systematic approach for direct solutions of
non-linear LS problems from a "geodetic" point of view.
Therefore, four non-linear adjustment problems are investigated:
the fit of a straight line to given points in 2D and in
3D, the fit of a plane in 3D and the 2D symmetric similarity
transformation of coordinates. For all these problems a direct
LS solution is derived using the same methodology by
transforming the problem to the solution of a quadratic or
cubic algebraic equation. Furthermore, by applying TLS all
these four problems can be transformed to solving the respective
characteristic eigenvalue equations. It is demonstrated
that the algebraic equations obtained in this way
are identical with those resulting from the LS approach. As
a by-product of this research two novel approaches are presented
for the TLS solutions of fitting a straight line to 3D
and the 2D similarity transformation of coordinates. The
derived direct solutions of the four considered problems
are illustrated on examples from the literature and also numerically
compared to published iterative solutions.

Published: June 2016

Abstract
As a result of the conducted investigations of the level fluctuations in lake naroch the initial data are divided into 3 components: a polynomial regression that makes it possible to find out an independent on time law of trajectory, a periodic component of sinusoidal type and a residual sequence of independent random quantities. Modeling of the trajectory fluctuations is based on the deterministic part, consisting of the regression of the 8th order and periodic component, and also the random part, consisting of independent equally distributed quantities. Using this model it can be modeled the trajectory of the level fluctuations in lake naroch. The modeled trajectory by 200 years long demonstrated the probability of exceeding of maximum annual level, equal 1 per cent.
Assessment of Bank Erosion, Accretion and Channel Shifting Using Remote Sensing and GIS: Case Study – Lower Course of the Bosna River
Authors: Lovric Novica , Tosic Radislav 
Published: June 2016

Abstract
River bank erosion, accretion and lateral channel migration are the most important geomorphological processes, which attract a great deal of attention from river engineering scientist over the last century. in the presented study, we assessed how the river’s shape and position have changed during 1958-2013 period using remote sensing and GIS. We have identified that the total area of bank erosion during given period equalled 8.3430 km2, of which 3.2593 km2 were on the left bank and 5.0837 km2 on the right bank. The total area of bank accretion from 1958 to 2013 equalled 10.7074 km2, of which 5.4115 km2 was on the left bank and 5.2958 km2 on the right bank. The Bosna riverbed average movement in the period 1958-2013 was established in the amount of 132.4 m. During this period, the average lateral channel migration was 2.5 m per year. The data presented here are significant for practical issues such as predicting channel migration rates for engineering and planning purposes, soil and water management.
