Effect of supplementation with vitamins E, C and β-carotene on antioxidative/oxidative status parameters in sows during the postpartum period
Authors: Szczubiał M. 
Published: July 2015

Abstract
The effect of vitamins E, C and β-carotene supplementation in sows on the parameters of antioxidative/oxidative status during the postpartum period was investigated. Twenty four primiparous sows, divided into two groups (experimental and control), were included in the study. After the half-way point of pregnancy until farrowing, each experimental sow received feed supplemented twice a week with 200 mg of vitamin E and 1000 mg of vitamin C, and additionally, 70 mg of β-carotene were administered via intramuscular injection, on day 14 and day 7 before farrowing. The control group was not supplemented. Blood samples were collected before supplementation (gestational day 57-58), 48 hours and 7 days after parturition. The following antioxidative and oxidative parameters were measured using spectrophotometric methods: glutathione peroxidase (GSH-Px), superoxide dismutase (SOD), catalase (CAT), vitamin C, vitamin E, thiobarbituric acid reactive substances (TBARS), and sulfhydryl groups (SH groups). In supplemented sows the erythrocyte activity of GSH-Px and CAT was found to be significantly higher on day 7 after farrowing and the activity of SOD was significantly higher at 48 hours postpartum, compared to the control group. The concentration of vitamins C and E in plasma of the supplemented group was found to be significantly higher and the content of TBARS was found significantly lower at both postpartum measurement points, compared to the control group. The content of SH groups was significantly higher on day 7 postpartum, compared to the control group. The study findings indicate that supplementation of pregnant sows with vitamins E, C and β-carotene in the second half of pregnancy has beneficial effects on the antioxidative/oxidative balance in the postpartum period by increasing the antioxidative potential and reducing lipid and protein peroxidation.

Authors: Bogucki Sz. , Noszczyk-Nowak A. 
Published: July 2015

AbstractHeart rate variability (HRV) is a well established mortality risk factor in both healthy dogs and those with heart failure. While the standards for short-term HRV analysis have been developed in humans, only reference values for HRV parameters determined from 24-hour ECG have been proposed in dogs. The aim of this study was to develop the reference values for short-term HRV parameters in a group of 50 healthy dogs of various breeds (age 4.86 ± 2.74 years, body weight 12.2 ± 3.88 kg). The ECG was recorded continuously for at least 180 min in a dark and quiet room. All electrocardiograms were inspected automatically and manually to eliminate atrial or ventricular premature complexes. Signals were transformed into a spectrum using the fast Fourier transform. The HRV parameters were measured at fixed times from 60-min ECG segments. The following time-domain parameters (ms) were analyzed: mean NN, SDNN, SDANN, SDNN index, rMSSD and pNN50. Moreover, frequency-domain parameters (Hz) were determined, including very low frequency (VLF), low frequency (LF) and high frequency (HF) components, total power (TP) and the LF/HF ratio. The results (means ± SD) were as follows: mean NN = 677.68 ± 126.89; SDNN = 208.86 ± 77.1; SDANN = 70.75 ± 30.9; SDNN index = 190.75 ± 76.12; rMSSD = 259 ± 120.17, pNN50 = 71.84 ± 13.96; VLF = 984.96 ± 327.7; LF = 1501.24 ± 736.32; HF = 5845.45 ± 2914.20; TP = 11065.31 ± 3866.87; LF/HF = 0.28 ± 0.11.

Abstract
The caudal mesenteric ganglion (CaMG) is a prevetrebral ganglion which provides innervation to a number of organs in the abdominal and pelvic cavity. The morphology of CaMG and the chemical coding of neurones in this ganglion have been described in humans and many animal species, but data on this topic in the sheep are entirely lacking. This prompted us to undertake a study to determine the localization and morphology of sheep CaMG as well as immunohistochemical properties of its neurons. The study was carried out on 8 adult sheep, weighing from 40 to 60 kg each. The sheep were deeply anaesthetised and transcardially perfused with 4% paraformaldehyde. CaMG-s were exposed and their location was determined. Macroanatomical observations have revealed that the ovine CaMG is located at the level of last two lumbar (L5 or L6) and the first sacral (S1) vertebrae. The ganglion represents an unpaired structure composed of several, sequentially arranged aggregates of neurons. Immunohistochemical investigations revealed that nearly all (99.5%) the neurons were DβH-IR and were richly supplied by VACHT-IR nerve terminals forming „basket-like” structures around the perikarya. VACHT-IR neurones were not determined. Many neurons (55%) contained immunoreactivity to NPY, some of them (10%) stained for Met-ENK and solitary nerve cells were GAL-positive. CGRP-IR nerve fibres were numerous and a large number of them simultaneously expressed immunoreactivity to SP. Single, weakly stained neurones were SP-IR and only very few nerve cells weakly stained for VIP.

Published: July 2015

AbstractThe contamination of agricultural crops with Fusarium mycotoxins poses one of the greatest problems in food production. Wild boars live in specific habitats and are physiologically sensitive to Fusarium mycotoxins, therefore, they are an interesting model for studies investigating the effects of the discussed toxin, in particular under low-dose exposure. The objective of this study was to determine potential effects of Fusarium mycotoxins ingested with naturally contaminated food on reproductive function based on the proliferation and apoptotic indices of ovarian follicles in female wild boars. The experiment was conducted on 40 wild boars inhabiting north-eastern Poland. The effect of seasonal variations in the quantity and quality of ingested food on the concentrations of Fusarium mycotoxins and their metabolites in the blood of wild boars was analyzed. The observed differences in toxin levels were accompanied by changes in proliferation and apoptotic indices. Proliferation processes were most intense in autumn-winter and were least advanced in winter-spring. The intensity of apoptotic processes was inversely correlated with proliferation.
Bluetongue in Europe and the role of wildlife in the epidemiology of disease
Authors: Niedbalski W. 
Published: July 2015

Abstract
The article reviews a current bluetongue (BT) epidemiological situation in Europe, BT restricted zones and the role of wild ungulates as a reservoir for bluetongue virus (BTV) and its transmission. BT has been eradicated from central and northern Europe, however it is still circulating in some regions of southern and south-eastern Europe. According to the recent information of the Directoriate General for Health and Consumer Affairs (DG SANCO) disease caused by BTV1 was spreading at the beginning of 2014 in Corsica (France). Moreover, four BTV1 cases were noticed in the west Spain (Cáceres province), 59 BTV4 outbreaks in south Spain (Andalusia), 10 in the region of Algarve in Portugal and about 200 outbreaks of BTV4 in Greece (Peloponesse and Evros regions). On 4th July the first outbreak of BTV4 was also confirmed at the south Bulgarian border and by 5th September 2014 disease was noticed in 21 of 28 administrative districts of Bulgaria. In August 2014 the BTV4 disease was reported in south-east of Romania and as for 8th September 184 outbreaks of BT were confirmed in 17 counties of this country. As of 3 September 2014 in Europe there has been fourteen BT-affected zones, in different regions of Italy, Spain, Portugal, Cyprus, Malta, France (Corsica), Greece, Bulgaria and Romania. Most species of wild ruminants and camelids are susceptible to BTV infection, although frequently asymptomatically. Wild sheep, bighorn and mouflon, are susceptible to BTV infection and can develop fatal clinical disease, as do domestic sheep. Experimental or natural infection of antelope, wapiti, musk, ox, bison, yak, white-tailed deer and African buffalo also produced clinical disease, whereas blesbock, mountain gazelle, roe deer, red deer and Eurasian elk did not show clinical sign after natural or experimental infection and infection was recognized by the presence of BTV viral RNA or specific antibodies. The wildlife due to the long-term carrier state may act as a reservoir for BTV and play an important role in its transmission.

Published: July 2015

Abstract
This paper presents assumptions and process of the forming of a risk assessment model for collision between a passenger ferry departing from or approaching port of Świnoujście and a chemical tanker carrying a dangerous cargo. In order to assess navigational safety on the basis of data obtained from AIS system, were prepared probabilistic domains of ships, which made it possible to estimate number of navigational incidents as well as their spatial distribution, that consequently allowed to determine potentially dangerous areas. The next phase was formulation of a simulative model intended for the calculating of probability of collision between the ferry and chemical tanker as well as the determining of characteristic scenarios for such collision. This paper presents also an analysis of consequences of the collision with taking into consideration a damage of cargo tanks.

Authors: Cho Dae Seung , Vladimir Nikola , Choi Tae Muk 
Published: July 2015

Abstract
Thin and thick plates, plates with holes, stiffened panels and stiffened panels with holes are primary structural members in almost all fields of engineering: civil, mechanical, aerospace, naval, ocean etc. In this paper, a simple and efficient procedure for the free vibration analysis of such elements is presented. It is based on the assumed mode method and can handle different plate thickness, various shapes and sizes of holes, different framing sizes and types as well as different combinations of boundary conditions. Natural frequencies and modes are determined by solving an eigenvalue problem of a multi-degree-of-freedom system matrix equation derived by using Lagrange’s equations. Mindlin theory is applied for a plate and Timoshenko beam theory for stiffeners. The applicability of the method in the design procedure is illustrated with several numerical examples obtained by the in-house developed code VAPS. Very good agreement with standard commercial finite element software is achieved.

An Integrated Approach to Real Estate (Porfolio) Management
Authors: Muczyński Andrzej 
Published: July 2015

Abstract
Real estate management activities evolved with the development of the real estate industry, the needs of property investors and general changes in the market environment. Today, these activities require a comprehensive approach on the one hand, but on the other, are more and more specialized. The paper presents an integrated view of real estate management on the example of a multidimensional basic concept of real estate management developed under German market conditions. Detailed analysis of this concept was preceded by a review of approaches to real estate management made on the basis of literature and own research. It was on this basis that opportunities and application fields of the integrated model of real estate management in Polish market conditions were characterized. The presented concept can be used both as a raster to harmonize real estate management activities and tasks in business practice, as well as a classification scheme for the evaluation of scientific research. This concept is an important step on the way to structuring and organizing real estate management as a professional service according to the indications of management science.

Abstract
Effective real estate management practice is needed to ensure that the property in Malaysia, including public schools, can be fully utilized. The purpose of this study is to identify the success factors of the real estate management of Malaysia’s public schools. To achieve this aim, a questionnaire was developed as a research tool. The respondents involved were representatives of public schools and officers from the state education department offices (on the basis of whom the total population was calculated) in Pulau Pinang, Malaysia. The respondents were chosen using a random sampling method. The success factors of managing property in public schools were identified by Exploratory Factor Analysis (EFA), using the principals of component analysis, the t-test, Cronbach’s alpha and mean analysis. The findings show that the majority of the respondents agreed that all of the listed 18 success factors within the 4 main factor groups as addressed in the survey are important for the efficient and effective improvement of real estate management, especially in Malaysian public schools.
Real Estate as a Subject of Spatial Conflict Among Central and Local Authorities
Authors: Źróbek-Różańska Alina , Zysk Elżbieta 
Published: July 2015

Abstract
Currently, real estate located in rural areas neighboring cities are under pressure to become a location for the realization of urban and metropolitan projects. Thus, spatial conflicts are an inherent characteristic of modern urban development. Such conflicts vary in terms of the scope, intensity and course they take. An interesting case illustrating the given issue can be the conflict over real estate owned by the State Treasury (central authority) and localized within the power of local authorities (gminas). Such a situation requires mediating and producing an outcome that satisfies the goals of both sides. The authors based the deliberations on the topic of spatial conflicts on the example of the relation between the Agricultural Property Agency division in Olsztyn (APA Olsztyn) and the smallest local administration units (gminas) located within the borders of the Warmia-Masuria (Województwo Warmińsko-Mazurskie) and Podlasie (Województwo Podlaskie) Provinces. The aim of the research was to describe the background for potential conflict and to study its proceedings. The aim was achieved through studies of relevant literature and data analysis.
Use of Statistical Models for Simulating Transactions on the Real Estate Market
Authors: Cellmer Radosław , Szczepankowska Katarzyna 
Published: July 2015

Abstract
The regularities and relations between real estate prices and the factors that shape them may be presented in the form of statistical models, thanks to which the diagnosis and prediction of prices is possible. A formal description of empirical observation presented in the form of regressive models also offers a possibility for creating certain phenomena in a virtual dimension. Market phenomena cannot be fully described with the use of determinist models, which clarify only a part of price variation. The predicted price is, in this situation, a special case of implementing a random function. Assuming that other implementations are also possible, regressive models may constitute a basis for simulation, which results in the procurement of a future image of the market.
Simulation may refer both to real estate prices and transaction prices. The basis for price simulation may be familiarity with the structure of the analyzed market data. Assuming that this structure has a static character, simulation of real estate prices is performed on the basis of familiarity with the probability distribution and a generator of random numbers. The basis for price simulation is familiarity with model parameters and probability distribution of the random factor.
The study presents the core and theoretical description of a transaction simulation on the real estate market, as well as the results of an experiment regarding transaction prices of office real estate located within the area of the city of Olsztyn. The result of the study is a collection of virtual real properties with known features and simulated prices, constituting a reflection of market processes which may take place in the near future. Comparison between the simulated characteristic and actual transactions in turn allows the correctness of the description of reality by the model to be verified.

Published: July 2015

Abstract
An innovative technique which is similar to a natural process, i.e., biogeochemical (carbonate) diagenesis, is proposed to construct a hybrid embankment. In this study, the hybrid embankment is defined as a soil embankment which has a microbially induced framework structure of sand sheets and columns in the soft soil matrix. The sand materials are cemented with magnesium-calcite or dolomite, induced by ureolytic microbes. To design and construct hybrid embankments, fundamental problems, such as feasibility in terms of stability, geoenvironmental engineering practices, etc., are examined and discussed. It was shown that the hybrid embankment can be environmentally friendly and also can contribute solving technical and financial problems encountered in actual practice.
Vertical and horizontal permeability measurements in organic soils
Authors: Malinowska Edyta E. , Szymański Alojzy 
Published: July 2015

Abstract
The paper is referring to vertical and horizontal laboratory permeability measurements in soft organic soils. The estimation of anisotropic permeability in soft organic soils, as peats, requires to use a special apparatus and the knowledge of proper analysis of the test results. During loading the void ratio decreases substantially that causes the changeability of the permeability. The change of permeability during the compression is very important because of the influence of the consolidation co-efficient. Initial strain in soft organic soils appears very quickly, just after loading, and brings immediately the decrease of permeability. In most of the estimations, it is assumed that during the consolidation process the water flows just in the vertical direction. In soft organic soils, like peats, the consolidation theory should consider the changes of mechanical and physical properties in consolidation period, in both directions. The direct measurement of vertical and horizontal permeability of organic soil and the non-Darcian flow theory may be of considerable importance in estimating pore water pressure dissipation, and settlement rates in the consolidation model. In the paper, the method of investigation and the test results of the vertical and horizontal permeability are presented. The Modified Rowe Cell Set for obtaining consolidation and flow characteristics in different directions is used.
