Published: November 2017

Abstract
The study presents the effects of precipitation on the amount and quality of raw sewage entering a sewage treatment plant in Wodzisław Śląski. It covers a six-year period between January 2010 and December 2015. The research period was divided into seven classes of precipitation intensity. The classes were characterized for their basic descriptive statistics of the raw sewage entering the investigated sewage treatment plant (STP). Data obtained from the collected material and derived from an analysis indicated a considerable influence of precipitation on the amount of sewage entering the investigated facility. Mean amount of sewage entering the STP was by 10.5% (884.9 m3·d-1) greater in B class and by 69.6% (6,153.9 m3·d-1) greater in G class than during dry weather. Individual classes of precipitation intensity were compared for their mean values of raw sewage contamination. Precipitation intensity was found to significantly affect concentrations of the investigated parameters of raw sewage contamination. Basic parameters of sewage contamination (BOD5, CODCr, total suspended solids) were determined and their basic descriptive statistics, such as median, mean, minimum and maximum value, standard deviation and coefficient of variation were calculated.

Abstract
An increasing importance of the social functions of the forest entails the necessity to modify forestry management in a way which would ensure its social acceptance. This mainly concerns those parts of the forest that are “most visible”, in the surroundings of roads, tourist trails, as well as water bodies. The article discusses the importance of view analyses in forest landscaping. On the basis of the adopted methodological assumptions, the assessment of landscape resources of the forest in the vicinity of a water reservoir in the Kielce Forest District (Radom Regional Forest Directorate) has been made. Available ortophotomaps and aerial photographs taken by UAVs were used for view analyses together with elevation data collected through airborne laser scanning. The results obtained allow to make recommendations for the protection of the reservoir exposure as well as engineering forest management and silviculture. Consequently, the inclusion of visual analyses into the planning stage enables verification of the quality of forest management plans.
Reliability based rehabilitation of water distribution networks by means of Bayesian networks
Authors: Lakehal Abdelaziz , Laouacheria Fares 
Published: November 2017

AbstractWater plays an essential role in the everyday lives of the people. To supply subscribers with good quality of water and to ensure continuity of service, the operators use water distribution networks (WDN). The main elements of water distribution network (WDN) are: pipes and valves. The work developed in this paper focuses on a water distribution network rehabilitation in the short and long term. Priorities for rehabilitation actions were defined and the information system consolidated, as well as decision-making. The reliability data were conjugated in decision making tools on water distribution network rehabilitation in a forecasting context. As the pipes are static elements and the valves are dynamic elements, a Bayesian network (static-dynamic) has been developed, which can help to predict the failure scenario regarding water distribution. A relationship between reliability and prioritization of rehabilitation actions has been investigated. Modelling based on a Static Bayesian Network (SBN) is implemented to analyse qualitatively and quantitatively the availability of water in the different segments of the network. Dynamic Bayesian networks (DBN) are then used to assess the valves reliability as function of time, which allows management of water distribution based on water availability assessment in different segments. Before finishing the paper by giving some conclusions, a case study of a network supplying a city was presented. The results show the importance and effectiveness of the proposed Bayesian approach in the anticipatory management and for prioritizing rehabilitation of water distribution networks.
Studying the effect of a variation in the main parameters on stability of homogeneous earth dams using design experiment
Authors: Lakehal Rida , Djemili Lakhdar 
Published: November 2017

Abstract Deterministic approaches such as the limit equilibrium method (LEM) especially Bishop modified method has been traditionally used to evaluate the stability of embankment dams. However, the uncertainty associated with the material properties necessitates the use of the probabilistic method to account the sensitivity of this uncertainty on the response of the deterministic approaches. In this study, the authors propose the application of design experiment, especially central composite design (CCD) to determine the effects of independent uncertain parameters on the response of stability. A second-order polynomial model with cross terms is used to create an approximating function referred to as response surface for the implicit limit state surface, for which the input data were provided by stability analyses of different heights of homogeneous earth dams (10 m, 20 m, and 30 m) with a depth ratio of DH = 1.5 and a circular slip surface using the Bishop modified limit equilibrium method. The proposed models obtained from this application represent higher prediction accuracy. The study of the effect of geotechnical parameters (material properties of embankment) on safety factor show the importance of individual factors in level of linear effect with a positive effect of c’ or φ’ and a negative effect of H, γd, γsat and significant influence of two-factors interaction, the effect of c’ highly dependent on H, β, γd and φ’. Moreover, the effect of φ’ is dependent on the values of H and β. Lastly, the optimization of safety factor with respect to the range of values of material properties was made, and two failures modes are discussed which are (φ’, c’ reduction and γd increase).
Impact of meteorological drought on crop water deficit and crop yield reduction in Polish agriculture
Authors: Łabędzki Leszek Ł , Bąk Bogdan 
Published: November 2017

Abstract
The study presents the quantification of the effect of meteorological drought on crop water deficit and crop yield reduction in different agro-climatic regions of Poland. The regression equations describing the relationship between the standardized precipitation index SPI (meteorological drought) and the crop drought index CDI (evapotranspiration reduction) were used in a first step. Then the FAO equation describing the relationship between CDI and yield reduction was used. Crop water deficit measured by CDI is spatially differentiated and depends on the intensity of meteorological drought and soil water availability. The greatest evapotranspiration reduction is found for late potato growing in the central-west Poland (30-60%). The smallest reduction of evapotranspiration was stated for winter rape (12-16%) in the same region on soils with small water retention and no reduction can be on soils with large water retention. A good correlation between estimated and observed yield reduction was found. Potential yield reduction of late potato can reach more than 50% in central Poland. Least yield reduction is for winter wheat and winter rape. The main advantage of the method used in the study is the combination of meteorological drought, soil water retention capacity, evapotranspiration, soil water balance and crop yield, and so help provide more accurate assessments.
Specific features of development of selected agricultural problematic areas in the land consolidation process

Published: November 2017

AbstractDevelopment of the Polish agriculture and its production abilities are spatially diversified. At present, in Poland agricultural areas may be distinguished which may successfully compete with the agriculture in the European Union countries. However, areas where private farms run their businesses on the verge of profitability or below also exist in Poland. Those areas are called agricultural problematic areas (OPR), depression areas, areas not useful for agricultural purposes, marginal lands etc. It is estimated that OPR covers over 60-70% of our country. Land consolidation is the process which improves the spatial structure of rural areas, including problematic areas. When this geodetic process is performed it is possible to interpret specific features of selected agricultural problematic areas and to propose alternative and the most effective ways of development of the discussed areas. As a result of those agricultural-and-development operations rural areas are becoming competitive and improve the living conditions. However, they are performed on a very small scale, in recent years this area is about 5900 hectares per year.

Published: November 2017

Abstract
A previously unpublished marble fragment from the Cesnola collection at the Turin University Museum of Anthropology and Ethnography bears an incomplete Phoenician inscription, a dedication to Eshmun-Melqart considered lost since 1869 (CIS I 26). The inscription allows to interpret the object bearing the dedication as a votive stone bowl from the late Classical Phoenician sanctuary of Kition-Batsalos in Cyprus, and it provides the opportunity to retrace the history of the Cesnola collection of Cypriote antiquities at the University Museum of Turin.
Hermes a-re-ja (PY Tn 316): a new interpretation
Authors: Macedo José Marcos 
Published: November 2017

Abstract
A long-standing consensus among Mycenaean scholars is that a-reja, an epithet of Hermes in the Pylos tablet Tn 316, must be somehow related to Ares, the war god. Hermes Areiās would be either a derivative in *-ās of Ares or, according to a recent suggestion, an abbreviated compound in the first member of which Ares would figure. The present paper argues for a different solution, taking a-re-ja (dat.) /aleii̯āi/ as an apposed noun epithet of the root *h2leu̯- ‘to ward off’. Nouns in apposition to divine names are not uncommon in 1st millennium Greek (type Artemis Εὐλοχία ‘Good Delivery’), and Hermes Aleia ‘(active) Protection’ or ‘Defense’ fits neatly with Hermes’ character as a helping deity and a god of boundaries, as shown both in the myths related to him and in several of his epicleses in alphabetic Greek. Aleiă is best taken as a feminine verbal derivative in *-ih2: this type is the source of other action nouns that are either personified or have a religious background, such as αἶσα ‘destiny’ and μοῖρα ‘fate’. Furthermore, Aleia can be viewed as an independent testimony of the *-u̯i̯- > *-i̯i̯- development in Mycenaean (type i-je-re-ja ‘priestess’).

Published: November 2017

Abstract
The main advantage of magnesium and its alloys is high specific strength and biocompatibility. A modern approach to magnesium-based materials preparation is powder metallurgy. This technique allows preparation of new materials with a unique structure, chemical composition, and controlled porosity. In this study, cold compaction of magnesium powder was studied. Magnesium powder of average particle size of 30 μm was compacted applying pressures of 100 MPa, 200 MPa, 300 MPa, 400 MPa and 500 MPa at laboratory temperature. Influence of compacting pressure was studied with microstructural and electrochemical corrosion characteristics analysis. The resulting microstructure was studied in terms of light and electron microscopy. Obtained electrochemical characteristics were compared with those of wrought magnesium. Compacting pressure had a significant influence on microstructure and electrochemical characteristics of prepared bulk magnesium. With the increase in compaction pressure, the porosity decreased. Compacting pressures of 300 MPa, 400 MPa and 500 MPa led to the similar microstructure of the prepared material. Polarization resistance of compacted magnesium was much lower and samples degraded faster when compared to wrought magnesium. Also, the corrosion degradation mechanism changed due to the microstructural differences between the material states.

Published: November 2017

Abstract
The paper evaluates extent of corrosion damage to composite glass-fibre fabric reinforcement in environment simulating concrete pore solutions (pH 12.6, 13.0, 13.5) and carbonated concrete contaminated with chlorides (pH 8.1 + Cl-) using the FT-IR and SEM/EDS techniques. Also, the effect of corrosion damage on tensile strength of segmented glass fibre as well as the presence of specific protective organic coating on glass fibre were studied. The results demonstrate local corrosion damage of samples at pH 13.5 and on the other hand high stability in environment simulating carbonated concrete and carbonated concrete contaminated with chlorides. The study also suggests unevenness of organic coating with occurrence of localized porosity which is related to aforementioned corrosion damage. Corrosion damage in FT-IR spectra manifests by changes in peaks signalling hydrolysis of protective organic coating and occurrence of peaks suggesting presence of Ca2+ rich corrosion products.
Materials for use in calcium looping technology for CCS – corrosion processes in high-temperature CO2
Authors: Poláčková J. , Petrů J. , Janák M. , Berka J. , Krausová A. 
Published: November 2017

Abstract
Carbon Capture and Storage (CCS) technologies are a perspective solution to reduce the amount of CO2 emissions. One of promising methods is Ca-looping, which is based on carbonation and calcination reactions. During both of these processes, especially calcination, high temperatures (650-950°C) are required. This means high demands on the corrosion resistance of equipment materials. Therefore, we carried out a study to suggest materials with suitable properties for calciner construction, which have to be particularly heat resistant: stainless steels (AISI 304, AISI 316L and AISI 316Ti) and nickel alloys (Inconel 713, Inconel 738, Incoloy 800H). A special device simulating calciner environment was built for this purpose. Chosen materials were tested in temperature 900°C, atmospheric pressure and gaseous environment with composition that can be possible in a calciner. The surfaces of materials were evaluated to determine composition and properties of formed oxide layers. High temperature oxidation was observed on all tested materials and oxide exfoliation occurred on some of tested materials (304, 316L).
Frugivory and potential seed dispersal by the exotic-invasive marmoset Callithrix jacchus (Primates, Callitrichidae) in an urban Atlantic Forest, Rio de Janeiro, Brazil

Published: November 2017

Abstract
The common marmoset, originally from Northeastern Brazil, has been introduced into several Brazilian states as a result of illegal traffic. Despite the long history of introduction, few studies have described the diet of this primate in regions where it is exotic and none have evaluated its role as a seed disperser. The importance of fruits in the diet of Callithrix jacchus and its potential as a seed disperser were investigated in the Tijuca National Park (TNP, 3.593 ha), southeastern Brazil, where the species is exotic. Data were collected from September 2013 to January 2015, through focal observations. A sampling effort of 361 h of observation resulted in 60 independent feeding records. Fruits were the most often consumed item, comprising 48.3% of the observed feeding records, followed by gum (30%), invertebrates (18.3%) and lichens (3.3%). Seeds from four out of 13 species were swallowed and seeds from seven additional species were found intact in collected feces. These results show C. jacchus’ potential to act as a seed disperser for some plant species, and that should be considered for managing this primate in TNP, where other callitrichids are absent.
Effects of consumer-producer interactions in alternative food networks on consumers’ learning about food and agriculture

Published: November 2017

Abstract
In the recent literature, Alternative Food Networks (AFN) are discussed as a promising approach, at the urban-rural interface, to meeting the challenges of the current agri-food system. Consumer-producer collaboration is seen as a characteristic feature in this context. What is lacking, however, are general concepts for describing the topics of consumer-producer interactions (CPI). The present study aims (1) to develop an analytical framework relying on six CPI domains and (2) to apply it to investigate CPI effects on consumers’ learning about and appreciation of agriculture. We conducted 26 guided interviews with consumers and producers of the three most frequent AFN types in Germany: community-supported agriculture (CSA), food coops, and self-harvest gardens. The results show that AFN participation enhances consumers’ learning about food (seasonality, cooking/nutrition, housekeeping aspects) and agricultural production (farmers’ perspectives, cultivation). Our results show that consumer’s learning is influenced by certain CPI domains, and each AFN type can be described by distinctive CPI domains. This led to the conclusion that specific AFN types open up specific learning channels and contents, with consumers learning from producers. AFNs at the urban-rural interface exploit knowledge of rurality.
Poisson-Fermi Formulation of Nonlocal Electrostatics in Electrolyte Solutions
Authors: Liu Jinn-Liang , Xie Dexuan , Eisenberg Bob 
Published: November 2017

Abstract We present a nonlocal electrostatic formulation of nonuniform ions and water molecules with interstitial voids that uses a Fermi-like distribution to account for steric and correlation efects in electrolyte solutions. The formulation is based on the volume exclusion of hard spheres leading to a steric potential and Maxwell’s displacement field with Yukawa-type interactions resulting in a nonlocal electric potential. The classical Poisson-Boltzmann model fails to describe steric and correlation effects important in a variety of chemical and biological systems, especially in high field or large concentration conditions found in and near binding sites, ion channels, and electrodes. Steric effects and correlations are apparent when we compare nonlocal Poisson-Fermi results to Poisson-Boltzmann calculations in electric double layer and to experimental measurements on the selectivity of potassium channels for K+ over Na+.

Published: November 2017

Abstract
The paper presents the specifics of a laser-assisted labial frenectomy in a pediatric patient, with emphasis on the surgical technique, the laser parameters, patient’s compliance and postoperative outcome. A 9-year-old girl was referred to the University Department of Oral Surgery for labial frenectomy for orthodontic reasons. The clinical examination and evaluation revealed the presence of an aberrant labial frenum (class IV according to Placeket et al.) and a 3 mm wide medial diastema. A penetrating frenum caused a significant problem in the closure of the diastema during the orthodontic treatment, and a frenectomy was indicated. A conventional frenectomy is carried out with a scalpel excision followed by placement of few stitches. Some degree of post-operative discomfort as well as the need for a return visit to remove the stitches can be anticipated. The patient was in good general health but anxious about the surgical intervenetion, and hence Er. YAG laser frenectomy was suggested. The surgery was performed with Er.YAG laser (Fotona Fidelis III) and a non-contact hand piece, working with long pulse mode (LP), energy (E) of 120 mJ, frequency of 15 Hz and power of 1.80 W. The surgery was fast and easy to perform. The cooperation with the patient during treatment was excellent. The bleeding was scarce and the visibility was not compromised. Sutures were not necessary. The postoperative period was uneventful, pain-free, without swelling or signs of infection. No painkillers or antibiotics were used. A fibrin coating was visible the following day. The wound healing process was completed three weeks after surgery, with minimal scar. This laser is suitable to be used in soft-tissue proceduresin pediatric patients.

Published: November 2017

Abstract
Aims. The prenatal prediction of fetal maturity is very important, since neonatal respiratory distress syndrome (RDS) is one of the biggest causes of neonatal mortality.
Our aim was to investigate a new non-invasive method for prediction of fetal maturity and to determine in which group according to gestational age of the fetus, the treatment works the best and in which cases it is necessary to be repeated.
Methods. We examined 60 patients (30 with impending preterm delivery, divided in 3 groups: 28-30, 30-32, and 32-34 gestational weeks and 30 controls), at the University Clinic for Gynecology and Obstetrics, Medical Faculty, University “Ss. Cyril and Methodius”, Skopje, R. Macedonia.
Fetal maturity was examined using ultrasound histogram from fetal lungs and liver, correlated with gestational age and postpartum RDS. Where possible, we performed amniocentesis for lamellar body count (LBC) to correlate our results with the current invasive method for prediction of fetal maturity.
Results. Pre-therapy investigation showed a strong fetal immaturity in 28-32 weeks of gestation and less evident fetal immaturity in 32-34 weeks of gestation. Seventy-two hours post-treatment, fetal maturation was low in the first group, higher in the second and the highest in the third group. Amniocentesis for LBC showed correlation with the ultrasound results. Postpartum results were correlated with pre-delivery ultrasound and showed significance of p <0.05.
Conclusion. The results obtained in our study were with high significance, and they were in correlation with other similar studies. However, more extensive investigations should be made to replace the current invasive technique.
