A Parametric Testing Of The Firefly Algorithm In The Determination Of The Optimal Osmotic Drying Parameters Of Mushrooms
Authors: Yeomans Julian Scott 
Published: May 2015

Abstract
The Firefly Algorithm (FA) is employed to determine the optimal parameter settings in a case study of the osmotic dehydration process of mushrooms. In the case, the functional form of the dehydration model is established through a response surface technique and the resulting mathematical programming is formulated as a non-linear goal programming model. For optimization purposes, a computationally efficient, FA-driven method is used and the resulting optimal process parameters are shown to be superior to those from previous approaches. The final section of this study provides a computational experimentation performed on the FA to analyze its relative sensitivity over a range of the two key parameters that most influence its running time.

Published: May 2015

Abstract
Spa garden in Daruvar ‘Julius’s Park’ is the oldest spa garden in continental Croatia. The counts Jankovich and their successors created the garden during the 18th and 20th century. The garden resumed its nowadays form and surface in the time of count Julius Jankovich in the mid-19th century and it was named after him. The garden is protected as a cultural heritage. The garden’s renovation is seen as an urban, architectural and landscape unity and it attempts to affirm the missing and neglected parts of the garden, to provide technological and municipal space modernization and to make a pleasant urban garden ambiance with new facilities and high space arrangement qualities, contributing to the economic development of the local community.
Monetary Policy Objectives During the Crisis: An Overview of Selected Southeast European Countries
Authors: Krstevska Aneta 
Published: May 2015

Abstract
The recent global crisis brought many challenges to the central bankers worldwide, including the issue of monetary policy objectives. In this view, besides price stability maintenance, a special attention by central bankers during the crisis was given to the output stabilization. This paper explores this issue on the case of a group of countries from Southeast Europe (SEE). For this purpose, rather simple analysis of the policy rate and output gap as well as output gap variability by countries have been provided, aimed at giving some initial insights of the monetary policy and output stabilization during the crisis. Our findings pointed that the central banks in the analysed SEE countries paid attention to the output stabilization, specifically during the crisis period and that was presumably enabled by controllable inflation developments.

Abstract
The Internet of Things (IoT) is a technological revolution that represents the future of computing and communications. One of the most important challenges of IoT is security: protection of data and privacy. The SSL protocol is the de-facto standard for secure Internet communications. The extra energy cost of encrypting and authenticating of the application data with SSL is around 15%. For IoT devices, where energy resources are limited, the increase in the cost of energy is a very significant factor. In this paper we present the energy efficient SSL protocol which ensures the maximum bandwidth and the required level of security with minimum energy consumption. The proper selection of the security level and CPU multiplier, can save up to 85% of the energy required for data encryption.
The development of physical geodesy during
1984-2014 – A personal review
Authors: Sjöberg Lars E. 
Published: May 2015

Abstract
This article is a personal review of the development
of physical geodesy during 1984-2014. The period
is characterized by an intensive advance in both data
and theory to meet the growing technical demands in
GPS/GNSS applications and scientific needs in geoscience.
As a result,many parts of theworld are nowmapped with a
1cmdetailed geoid model, and the global long- to mediumwavelengths
of the gravity field and geoid are homogeneously
determined to 1 mGal and 1 cm by satellite-only
dedicated satellite gravity missions. The future can expect
to see even higher demands for accuracy and reliability to
satisfy the specifications for a pure geoid model based vertical
datum.
On the role of rock fragments and initial soil water content in the potential subsurface runoff formation
Authors: Hlaváčiková Hana , Novák Viliam , Holko Ladislav 
Published: May 2015

Abstract
Stony soils are composed of fractions (rock fragments and fine soil) with different hydrophysical characteristics. Although they are abundant in many catchments, their properties are still not well understood. This article presents basic characteristics (texture, stoniness, saturated hydraulic conductivity, and soil water retention) of stony soils from a mountain catchment located in the highest part of the Carpathian Mountains and summarizes results of water flow modeling through a hypothetical stony soil profile. Numerical simulations indicate the highest vertical outflow from the bottom of the profile in soils without rock fragments under ponding infiltration condition. Simulation of a more realistic case in a mountain catchment, i.e. infiltration of intensive rainfall, shows that when rainfall intensity is lower than the saturated hydraulic conductivity of the stony soil, the highest outflow is predicted in a soil with the highest stoniness and high initial water content of soil matrix. Relatively low available retention capacity in a stony soil profile and consequently higher unsaturated hydraulic conductivity leads to faster movement of the infiltration front during rainfall.
Validating Sensitive Questions: A Comparison of Survey and Register Data
Authors: Kirchner Antje 
Published: May 2015

Abstract
This article explores the randomized response technique (RRT) - to be specific, a symmetric forced-choice implementation - as a means of improving the quality of survey data collected on receipt of basic income support. Because the sampled persons in this study were selected from administrative records, the proportion of respondents who have received transfer payments for basic income support, and thus the proportion of respondents who should have reported receipt is known.
The article addresses two research questions: First, it assesses whether the proportion of socially undesirable responses (indication of receipt of transfer payments) can be increased by applying the RRT. Estimates obtained in the RRT condition are compared to those from direct questioning, as well as to the known true prevalence. Such administrative record data are rare in the literature on sensitive questions and provide a unique opportunity to evaluate the ‘more-is-better’ assumption. Second, using multivariate analyses, mechanisms contributing to response accuracy are analyzed for one of the subsamples.
The main results can be summarized as follows: reporting accuracy of welfare benefit receipt cannot be increased using this particular variant of the RRT. Further, there is only weak evidence that the RRT elicits more accurate information compared to direct questioning in specific subpopulations.
Soil management system in hazelnut groves (Corylus sp.) versus the presence of ground beetles (Coleoptera: Carabidae)
Authors: Nietupski Mariusz , Kosewska Agnieszka , Markuszewski Bogumił , Sądej Wojciech 
Published: May 2015

Abstract
Sustaining biodiversity as well as taking advantage of the natural environment’s resistance are the key elements which should be considered when designing integrated plans for the protection of hazelnut groves. An effort has been made in this study to analyse the impact of different soil cultivation methods in hazelnut groves, on the species composition and number of individuals in carabid assemblages (Coleoptera: Carabidae). Another aim was to determine which method of inter-row soil management had the least negative effect on assemblages of these beetles. Because of the type of habitat, the xerothermic species characteristic for southeastern Europe, i.e. Calathus ambiguus, Poecilus lepidus, Harpalus calceatus, and H. griseus, were the most numerous. The qualitative and quantitative analysis of the captured individuals implied that the optimal soil tillage system in young hazelnut groves is when soil is kept fallow with machines or chemicals, or when soil is covered with manure. The least favourable practice for the appearance of ground beetles of the Carabidae family is the use of polypropylene fabric, bark or sawdust, to cover soil
Formulation of the endophytic fungus Cladosporium oxysporum Berk. & M.A. Curtis, isolated from Euphorbia bupleuroides subsp. luteola, as a new biocontrol tool against the black bean aphid (Aphis fabae Scop.)
Authors: Bensaci Oussama Ali , Daoud Harzallah , Lombarkia Nadia , Rouabah Khamsa 
Published: May 2015

Abstract
Two formulations containing culture filtrates and conidial suspensions of the endophytic fungus Cladosporium oxysporum Berk. & M.A. Curtis, isolated previously from stems of Euphorbia bupleuroides subsp. luteola (Kralik) Maire, were experimentally tested for their aphicid activity against the black bean aphid Aphis fabae Scop. found in Algeria. It was shown that invert emulsions are more effective against aphids, than using aqueous suspensions. This was especially true for formulations containing culture filtrates. The relatively insignificant mortalities obtained by formulations containing conidial suspensions indicated a low infectious potential towards the aphids. The proteolytic activity seemed to be more important than the chitinolytic activity of the fungus against the black bean aphid A. fabae
‘Bois noir’: new phytoplasma disease of grapevine in Iran
Authors: Mirchenari Seyed Mehdi , Massah Amir , Zirak Leila 
Published: May 2015

Abstract
Recently, grapevines showing symptoms suggesting the ‘bois noir’ phytoplasma disease were observed in vineyards located in several central provinces of Iran. Polymerase chain reaction assays using phytoplasma universal primer pair P1A/P7A followed by primer pair R16F2n/R16R2 in nested PCR, confirmed the association of phytoplasmas with symptomatic grapevines. The results of RFLP analyses using HpaII, HinfI, MseI, RsaI, and TaqI restriction enzymes, indicated that grapevine phytoplasma isolates in these regions could be related to the 16SrXII group. Sequence analyses of the partial 16S rRNA gene confirmed that Iranian grapevine phytoplasmas are associated with ‘Candidatus Phytoplasma solani’. This is the first report of the ‘bois noir’ disease outbreak in Iran
Fusarium head blight (FHB) and Fusarium populations in grain of winter wheat grown in different cultivation systems
Authors: Lenc Leszek 
Published: May 2015

Abstract
Fusarium head blight (FHB) incidence, and colonisation of grain by Fusarium species on winter wheat grown in organic, integrated, and conventional systems as well as in monoculture, were studied locally in Poland, from 2002 to 2010. Fusarium head blight incidence differed throughout the study years. It was found to occur the most where rainfall was highest and where rainfall was the most prolonged before, during, and after flowering of wheat. Fusarium head blight incidence was generally less on wheat grown organically than on wheat grown in other systems. In some years, FHB was noted more in monocultures than in other systems. Fusarium poae was the most common species of FHB populations in wheat kernels, followed by F. avenaceum and F. tricinctum. Other species which occurred more rarely or sporadically were: F. culmorum, F. equiseti, F. graminearum, F. langsethiae, F. oxysporum, and F. sporotrichioides. There were found to be significant effects of the cropping system on grain colonisation by Fusarium in some years. There was a positive correlation between FHB incidence and number of kernels colonised and damaged by Fusarium, in all four systems. Inferences were drawn concerning the effects of different procedures in different production systems and the possible value for controlling FHB
Wave Propagation Due to an Embedded Seismic Source in a Graded Half-Plane with Relief Peculiarities Part I: Mechanical Model and Computational Technique
Authors: Fontara I.-K. , Wuttke F. , Parvanova S. , Dineva P. 
Published: May 2015

Abstract
This work addresses the evaluation of the seismic wave field in a graded half-plane with free-surface and/or sub-surface relief subjected to shear horizontally (SH)-polarized wave, radiating from an embedded seismic source. The considered boundary value problem is transformed into a system of boundary integral equations (BIEs) along the boundaries of the free-surface and of any sub-surface relief, using an analytically derived frequency-dependent Green’s function for a quadratically inhomogeneous in depth half-plane. The numerical solution yields synthetic seismic signals at any point of the half-plane in both frequency and time domain following application of Fast Fourier Transform (FFT). Finally, in the companion paper, the verification and numerical simulation studies demonstrate the accuracy and efficiency of the present computational approach. The proposed BIE tool possesses the potential to reveal the sensitivity of the seismic signal to the type and properties of the seismic source, to the existence and type of the material gradient and to the lateral inhomogeneity, due to the free-surface and/or sub-surface relief peculiarities.
Runoff formation in terms of changes in land use – Mściwojów water reservoir area/ Odpływ powierzchniowy w rejonie zbiornika wodnego Mściwojów w świetle planowanych zmian urbanistycznych
Authors: Radecki-Pawlik Artur , Wałęga Andrzej , Wojkowski Jakub , Pijanowski Jacek 
Published: May 2015

Abstract
Along the paper the size of peak runoff was assessed affected by the influence of changes in water catchment area by land use due to future planned agricultural changes. The investigations were conducted in the Winna Góra catchment area located in Mściwojów, Lower Silesian voivodship at the Mściwojów water reservoir. At present, the catchment is used as arable land, forest and meadows. In the future the area of sealed surfaces such as: roofs, roads and car parks will increase. This can contribute in the change of water balance components. Analyses has shown, that changes in the use of a catchment area lead to reduction of surface flow time from the catchment (less resistance to motion) - in effect it causes increase of the runoff volume at about 28%. The increase of the water runoff volume may have significant influence on the Winna Góra development and functions as well as volume of water run into the Mściwojów water reservoir. To counteract the results of adverse changes caused by the catchment sealing - it is recommended for the investigated area to apply a balanced approach. This would consist of retaining precipitation water in its place of origin.
Thermal conditions in Bydgoszcz Region in growing seasons of 2011–2050 in view of expected climate change/ Warunki termiczne w rejonie Bydgoszczy w okresie wegetacyjnym w latach 2011–2050 w świetle przewidywanej zmiany klimatu
Authors: Bąk Bogdan , Łabędzki Leszek 
Published: May 2015

Abstract
The paper presents an analyse of the scenario of expected changes in monthly mean air temperature of months in the growing season (April-September) and growing seasons of 2011-2050 in Bydgoszcz Region. Prediction of thermal conditions is made using regional climate model RM5.1 with boundary values taken from global model ARPEGE. When compared with the reference period 1971-2000, an increase of mean air temperature should be expected in most months and growing seasons of the years 2011-2050. The biggest positive change in the mean monthly temperature is predicted for July (1.5°C) and August (1.2°C). In 2011-2050 significant increase trends of air temperature change can be expected in April, June and August. According to the thermal classification proposed by Lorenc, normal, slightly warm and slightly cool months and growing periods will dominate. The frequency of normal and slightly cool growing periods will decrease and the frequency of slightly warm growing periods will increase.
The analysis of the impact of small retention on water resources in the catchment/ Analiza oddziaływania małej retencji na zasoby wodne zlewni
Authors: Mioduszewski Waldemar , Querner Erik P. , Kowalewski Zbigniew 
Published: May 2015

Abstract
The aim of this study was to analyse the impact of selected small water retention measures on surface and groundwater level in river basins. The study was limited to the analysis of measures like small water reservoirs, restoration of bogs and reconstruction of drainage systems in the river valleys. A few study cases were described.
Dutch SIMGRO numerical model describing the regional surface water and groundwater flow has been used for simulation modelling of different cases.
The result of the study has shown that small retention measures are a good and effective method to increase the ability to retain water in the small river basins. Construction of small water reservoirs and weirs on ditches and creeks and restoration of drained bogs can limit the fast outflow of precipitation and melting water from the catchment.
The study has proved that the small water retention measures can be helpful for flood protection and in decreasing of drought threats in small river basins.

Natural Organic Matter in Ecosystems - a Review
Authors: Kosobucki Przemysław , Buszewski Bogusław 
Published: May 2015

Abstract
One of the most essential parameters limiting the potential use of the ecosystem (soil, water) is the content of the organic matter. The natural organic matter (NOM) is a ubiquitous component of the lithosphere and hydrosphere that constitutes one of the largest reservoirs of the carbon in the environment. Natural organic substances play several important functions in ecosystems and they are necessary for their normal functioning. Despite many years of the research and using many advanced analytical techniques, their structure has not been fully explained. The main aim of this review is to present the actual state of the knowledge about the natural organic matter and provide a comprehensive overview of the research that has explored up to date in this matter. The additional attention was focused on the relations within and between humic and fulvic acids in terrestrial and aquatic environments. Special attention is focused on the analytical methods used to analysis natural organic matter

Abstract
The in vitro cell cultures of Vitis vinifera L. cv. St. Laurent were treated with two elicitors - synthetic methyl jasmonate and natural, prepared from grapevine plant infected with the Phaeomoniella chlamydospora, the agent causing the Esca disease of grapevine. Efficiency of phenolic compounds production after elicitation of cell culture was analysed immediately after treatment (15 min, 30 min, 60 min) and later (after 24, 48, and 72 hours). The cell growth and content of phenolic compounds (+)-catechin, (-)-epicatechin, p-coumaric acid, syringaldehyde, rutin, vanillic acid, and trans-resveratrol were analysed in cultivated cells as well as in cultivation medium. Pch-treatment increased production of total polyphenols the most significantly 15 min after the elicitation and in optimal time was 2.86 times higher than in nonelicited culture and 1.44 times higher than in MeJa induced cell culture.
Modelling of a passive autocatalytic hydrogen recombiner – a parametric study
Authors: Rożeń Antoni 
Published: May 2015

Abstract
Operation of a passive autocatalytic hydrogen recombiner (PAR) has been investigated by means of computational fluid dynamics methods (CFD). The recombiner is a self-active and self-adaptive device used to remove hydrogen from safety containments of light water nuclear reactors (LWR) by means of a highly exothermic reaction with oxygen at the surface of a platinum or palladium catalyst. Different turbulence models (k-ω, k-ɛ, intermittency, RSM) were applied in numerical simulations of: gas flow, heat and mass transport and chemical surface reactions occurring in PAR. Turbulence was found to improve mixing and mass transfer and increase hydrogen recombination rate for high gas flow rates. At low gas flow rates, simulation results converged to those obtained for the limiting case of laminar flow. The large eddy simulation technique (LES) was used to select the best RANS (Reynolds average stress) model. Comparison of simulation results obtained for two- and three-dimensional computational grids showed that heat and mass transfer occurring in PAR were virtually two-dimensional processes. The effect of hydrogen thermal diffusion was also discussed in the context of possible hydrogen ignition inside the recombiner.

Published: May 2015

Abstract
The Nd2Fe14B cylindrical magnets were treated with water solutions of alkali, acid, and salt. Mössbauer spectroscopy was applied to study the composition and properties of the surface material of the treated magnets. It is shown that the main phase of the permanent Nd2Fe14B magnet partly decomposes. The released α-Nd at the grain boundaries interacts with water and forms neodymium hydroxide matrix, and the released Fe diffuses into it. The presence of Fe-Nd(OH)3 is reflected in the paramagnet doublet in the Mössbauer spectra of treated neodymium magnets.
