The Impact of Cadmium on Photosynthetic Performance and Secondary Metabolites in the Lichens Parmelia sulcata, Flavoparmelia caperata and Evernia prunastri
Authors: Maslać Ana , Maslać Maja , Tkalec Mirta 
Published: October 2016

Abstract
Lichens are one of the most common air quality bioindicators. Airborne heavy metal pollution causes various physiological changes in lichens, but sensitivity to metal pollution is species specific. In this research, three lichen species (Parmelia sulcata, Flavoparmelia caperata and Evernia prunastri) were exposed to cadmium (50 mg L−1) in laboratory conditions. Photosynthetic efficiency of photosystem II and content of secondary metabolites were determined after one, three and eight days of exposure. In all investigated species treatment of lichen thalli with cadmium significantly changed Fv/Fm and RFd only after eight days of exposure. Quantification of metabolites showed a decreased content of the medullary depsidones salazinic acid (in P. sulcata) and protocetraric acid (in F. caperata) but increased content of cortical depside atranorin (in P. sulcata) and dibenzofurane usnic acid (in F. caperata) after cadmium exposure. However, no changes in secondary metabolites were found in E. prunastri. Results show that investigated species are relatively resistant to short-term cadmium-exposure and that secondary metabolites could have an important role in the protection of primary metabolism from negative cadmium impacts, at least in some species.

Published: October 2016

AbstractSarraceniais a genus of carnivorous plants characterised by leaves modified into pitchers which lure, trap and digest insects. The aim of this study was to analyse the photochemical efficiency and contents of photosynthetic pigments and phenolic compounds in different pitcher parts – operculum, wing, pitchertube upper part and pitcher-tube lower part of three morphologically differentSarraceniahybrids. The photochemical efficiency of the operculum and the pitcher-tube upper part was lower than that of the pitcher-tube lower part and wing, especially in hybrid B. In all hybrids, the wing had higher amount of chlorophyllathan other pitcher parts. In contrast, a higher amount of phenolic compounds, in particular anthocyanins, was measured in the operculum and the pitcher-tube upper part, parts which are red-coloured and participate in luring and trapping insects. Although there were some differences among the hybrids, the results show that amount of phenolic compounds and photosynthetic pigments as well as photochemical efficiency are related to the function of the pitcher part analysed.

Abstract
The theoretical basis for the indirect measurement approach of mean heat transfer coefficient for the packed bed based on the modified single blow technique was presented and discussed in the paper. The methodology of this measurement approach dedicated to the matrix of the rotating regenerative gas heater was discussed in detail. The testing stand consisted of a dedicated experimental tunnel with auxiliary equipment and a measurement system are presented. Selected experimental results are presented and discussed for selected types of matrices of regenerative air preheaters for the wide range of Reynolds number of gas. The agreement between the theoretically predicted and measured temperature profiles was demonstrated. The exemplary dimensionless relationships between Colburn heat transfer factor, Darcy flow resistance factor and Reynolds number were presented for the investigated matrices of the regenerative gas heater.

Authors: Trojanowicz Karol , Wojcik Wlodzimierz 
Published: October 2016

Abstract
Results of the studies for determining fractions of organic contaminants in a pretreated petrochemical wastewater flowing into a pilot Aerated Submerged Fixed-Bed Biofilm Reactor (ASFBBR) are presented and discussed. The method of chemical oxygen demand (COD) fractionation consisted of physical tests and biological assays. It was found that the main part of the total COD in the petrochemical, pretreated wastewater was soluble organic substance with average value of 57.6%. The fractions of particulate and colloidal organic matter were found to be 31.8% and 10.6%, respectively. About 40% of COD in the influent was determined as readily biodegradable COD. The inert fraction of the soluble organic matter in the petrochemical wastewater constituted about 60% of the influent colloidal and soluble COD. Determination of degree of hydrolysis (DH) of the colloidal fraction of COD was also included in the paper. The estimated value of DH was about 62%. Values of the assayed COD fractions were compared with the same parameters obtained for municipal wastewater by other authors.
Statistical Analysis of Causality between Capital Structure and Firm Profitability: Evidence from Bosnia and Herzegovina
Authors: Resić Emina , Mangafić Jasmina , Perić Tunjo 
Published: October 2016

Abstract
This research is designed to examine the relationship between the capital structure and profitability of non-financial firms in Bosnia and Herzegovina during the ten years period, from 2003-2012. The goal is to prove the existence of the relationship between the firm’s capital structure choice and its profitability. The analysis is extended by including the debt structure and differentiating between the types of debt such as the long-term and the short-term ones. Canonical correlation and multiple regression analysis are used. The results of the multivariate canonical correlation analysis provide support to a hypothesis that the capital structure and profitability have statistically significant relationships. Furthermore, the findings provide support that firms develop different patterns of profitability depending on the capital structure choice. We found that an increasing proportion of short-term debt and long-term debt in the overall liability of the firm reduces its profitability.

Published: October 2016

Abstract

Introduction: Pericardiocentesis is a procedure performed for diagnostic and therapeutic purposes, and it consists in draining the pericardial effusion liquid in sterile conditions. The accumulation of fluid in the pericardial space may be caused by several systemic conditions, including viral or bacterial infections, autoimmune disease, cancer, as well as thyroid malfunction. A rapidly growing pericardial effusion can lead to cardiac tamponade, and consequently to acute hypodiastolic heart failure.

Case report: We report the case of a 79-year-old female, without previously known cardiovascular pathologies, who presented to the Emergency Room due to a gradual deterioration in her health status. Imaging procedures included a chest X-ray and an echocardiography that confirmed the diagnosis of pericardial effusion. Pericardiocentesis was performed using cardiac ultrasound guidance, resulting in the draining of a small quantity of yellowish, partly haemorrhagic fluid. The patient's general condition did not improve, thus another pericardiocentesis was carried out, this time with fluoroscopical and cardiac ultrasound guidance, and 1200 milliliters of sero-haemorrhagic fluid was drained. The laboratory analysis revealed that the patient had hypothyroidism, and the cytological analysis of the drained pericardial fluid excluded a neoplastic origin, tuberculosis, and other infectious etiologies. The particularity of the case consists in a pericardial effusion evolving into cardiac tamponade, for which the pericardiocentesis was guided using echocardiographic, fluoroscopic and radiologic methods, because simple ultrasound-guided drainage was not efficient.

Conclusion: The superiority of a combined imaging-guided approach in cases of pericardial effusion recommends it as an alternative to a surgical procedure, guided solely by echocardiography, which is often used in cases of unsuccessful drainage of pericar-dial effusion fluid.

Abstract
Pyopericardium is an acquired disease associated with very high complication rates. Pyopericardium is a very rare form of pneumopericardium. The nontraumatic causes of pneumopericardium include gastro-pericardial fistula that can occur in refractory gastric ulcers, stomach or esophageal neoplasia, and in surgical interventions of the stomach, such as the Niessen fundoplication procedure. The case of life-threatening pneumopericardium associated with gastro-pericardial fistula resulting from the incarceration of a giant hiatal hernia is reported.
Characteristics of Logistics Outsourcing in Bulgaria: The Perspectives of the Logistics Service Providers and their Customers
Authors: Rakovska Miroslava 
Published: October 2016

AbstractThe increased demand and supply of logistics services bring together the logistics service providers (LSPs) and the companies that outsource logistics activities. LSPs stand in between those companies and their customers, thus playing an essential role for supply chain integration. If the two parties have different viewpoints of the processes in the supply chain, the fulfillment of the goal to satisfy the end customers may be hindered. The purpose of this article is two-fold: First, to investigate the characteristics of logistics outsourcing in Bulgaria from the perspectives of the logistics service providers and their customers, and more specifically, to compare their viewpoints concerning the motives for outsourcing, the methods and contents of communication and some relationship management aspects; Second, to assess the relations of the communication and relationship management aspects to customer satisfaction. This article is based on empirical data provided by 138 manufacturing and trading companies and 136 LSPs and collected through two structured questionnaires designed to address the researched issues. The data were analyzed using descriptive statistics and the independent samples t-test. The research found that the service related reasons for logistics outsourcing are prevailing and that LSPs overestimate, compared to manufacturing and trading companies, motives related to service, organizational capabilities and relationships, while more manufacturing and trading companies concern as important the availability of logistics assets and the provision of value-added services. The research also found that both the LSPs and their customers consider that the extent of sharing of knowledge and information essential for material flow integration is very low and that the usage of team meetings and joint teams is quite rare. Also, customers do not view their relationships with the LSPs as so collaborative as viewed by the LSPs. Furthermore, the research proved the existence of positive relationships between customer satisfaction and communication through team meetings and joint teams, knowledge sharing concerning material flow management and relationship management issues such as trust, mutual problem solving, understanding the logistics strategy of the other party and respecting its financial interests. The research findings may help fill in some of the gaps between LSPs and their customers. They point the need for LSPs to include in their service offerings more value-added services and to invest in assets that provide reliable and flexible services for their customers. The research also highlights the importance of knowledge sharing and trust building and reveals great potential for effective trust-based alliances between LSPs and their customers that could help them extract more competitive benefits from their relationships.
Perfect and ε-perfect simulation methods for the one-dimensional Kac equation
Authors: Corcoran Jem N. , Jennings Dale , VaughanMiller Paul 
Published: October 2016

Abstract
We review the derivation of the Kac master equation model for random collisions of particles, its relationship to the Poisson process, and existing algorithms for simulating values from the marginal distribution of velocity for a single particle at any given time. We describe and implement a new algorithm that efficiently and more fully leverages properties of the Poisson process, show that it performs at least as well as existing methods, and give empirical evidence that it may perform better at capturing the tails of the single particle velocity distribution. Finally, we derive and implement a novel “ε-perfect sampling” algorithm for the limiting marginal distribution as time goes to infinity. In this case the importance is a proof of concept that has the potential to be expanded to more interesting (DSMC) direct simulation Monte Carlo applications.

The cartographic materials auxiliary in the determination of the borders of Poland during the Paris Peace Conference (1919–1920) in the light of archival records
Authors: Konopska Beata 
Published: October 2016

Abstract
The work indicated in Polish literature as the cartographic basis for the negotiations of Polish issues at the Paris Peace Conference (1919–1920) is Eugeniusz Romer’s Geograficzno-statystyczny atlas Polski (Geographical and Statistical Atlas of Poland). Given the complicated fate of the atlas, the position of its author in the Polish delegation, and the multidisciplinarity and importance of the conference, it is worth considering whether this atlas really played such an important role, or whether this is merely a statement, a repeated assignment of this role, to stave off concealment or lack of knowledge about other cartographic materials developed and used for the same purpose. Therefore, the main aim of this study was to determine the level of use of cartographic documents other than the Geographical and Statistical Atlas of Poland in lobbying and official negotiations of Polish issues before and during the Paris Peace Conference. The research task was associated with an extensive archival query, which confirmed the fact that dozens of maps survived, mainly manuscripts, which were prepared before and during the conference. It should be concluded that the maps of E. Romer’s atlas constituted one set of many equally important cartographic documents which were used by the negotiators at the Paris Peace Conference.
Leadership Changes and Civil War Agreements: Exploring Preliminary Links
Authors: Lutmar Carmela , Terris Lesley 
Published: October 2016

Abstract
The emergence of civil wars as the predominant type of conflict in the twenty-first century has prompted scholars to reformulate and revisit many of the questions treated in the interstate conflict literature. One of these questions concerns the impact of leadership changes on policy decisions within the realm of war and peace. Studies have suggested that in interstate disputes, the coming to power of new leaders in one or both of the disputing governments increases the prospects of war termination. We argue that within the context of intrastate disputes this relationship is more complex and multilayered due to factors that are characteristic of rebel groups and civil wars. We suggest that leader overturns in rebel groups are likely to lead, under certain conditions to more, rather than less, hardline conflict positions, at least in the short term, thus hindering possible negotiation processes. We test our hypothesis on a dataset of leadership changes and agreements ending civil wars in Africa, 1975–2007.

Published: October 2016

Abstract
Plants belonging to Rhodiola kirilowii species, members of Rhodiola genus and Crassulaceae family, grow wildly in Tibet, Mongolia and China mountains and are traditionally used as adaptogens, antidepressants and anti-inflammatory remedies. Nowadays, R. kirilowii is cultivated in some countries, also in Poland. In our previous papers we reported immuno- and angio-modulatory effects of aqueous and hydro-alcoholic extracts of radix and rhizome of this plant in non-pregnant and pregnant mice. The aim of the present study was to evaluate the effect of feeding pregnant and further lactating mice these extracts on selected thymus function parameters in adult progeny. The counts of M-30+ apoptotic cells, in the thymuses obtained from progeny of mice fed during pregnancy and lactation water or 50% water-alcoholic extract of Rhodiola kirilowii, were significantly lower (p<0.05) than apoptotic cells counts observed in the control mice. No significant differences in the counts of IL-7-positive cells in the thymuses obtained from progeny of the control mice and mothers treated with water or hydro-alcohol extracts of Rhodiola kirilowii were observed.

AbstractThis study aimed to investigate antioxidant and anti-inflammatory activities of a commercial product of noni (Morinda citrifolia) juice. Carrageenan-induced rat paw edema was employed as inflammatory model. One control and three experimental groups were formed. Experimental groups were administered noni juice alone, noni juice+carrageenan, and carrageenan alone. Oxidant and antioxidant capacity were determined by d-ROMs test and BAP test, respectively. Plasma concentrations of endothelin-1 and leptin were measured by ELISA. Measurements were performed at zero time and 2nd hour of inflammation. Oxidant capacity decreased in noni-received groups at 2nd hour (p=0.019). Antioxidant capacity of the group which received noni alone was found to be higher at 2nd hour (p=0.036). Plasma concentrations of endothelin-1 and leptin were notably lower in noni-received groups (p=0.001 and p=0.021, respectively). The results show that the commercial noni juice investigated has pronounced antioxidant and anti-inflammatory activities.

Published: October 2016

AbstractThe objectives of this study were to determine the prevalence and antimicrobial resistance of coagulase-negative staphylococci (CNS) isolated from dairy cows with subclinical mastitis. Antimicrobial resistance in staphylococci were evaluated by breakpoint values specific to the species (EU-CAST). The presence of resistance-encoding genes was detected by multiplex PCR. A total of 191 CNS isolates were obtained. The CNS isolates were typically resistant to penicillin (67.4%), tetracyc-line (18.9%), and erythromycin (13.7%). CNS isolates (78.0%) were resistant to at least one antimicrobial compound, and 22.0% were multiresistant. The multiresistant isolates were predominantlyStaphylococcus chromogenes(28.6%),Staphylococcus warneri(19%) andStaphylococcus haemolyticus(14.3%). According to MIC pattern data, multiresistant isolates showed the highest resistance (p<0.05) rates to penicillin (85.7%), tetracycline (66.7%), and erythromycin (48.2%), but all of them were sensitive to daptomycin, oxacillin, qiunupristin/dalfopristin, and vancomycin.S. chromogenes (9.5%),S. haemolyticus(4.8%), andS. capitis ss capitis(2.4%) strains were resistant to methicillin; their resistance to oxacillin and penicillin was more than 8 mg/l. A high rate of resistance to penicillin was linked to ablaZ gene found in 66.6% of the isolated multiresistant CNS strains. Resistance to tetracycline via thetetK (38.1%) gene and penicillin via themecA (23.8%) gene were detected less frequently. GenemsrAB was responsible for macrolides and lincosamides resistance and detected in 28.6% of the CNS isolates. Antimicrobial resistance genes were identified more frequently inS. epidermidis,S. chromogenes, andS. warneri.

Published: October 2016

Abstract
The role of image classification based on multi-source, multi-temporal and multi-resolution remote sensed data is on the rise in the environmental studies due to the availability of new satellite sensors, easier access to aerial orthoimages and the automation of image analysis algorithms. The remote sensing technology provides accurate information on the spatial and temporal distribution of land use and land cover (LULC) classes. The presented study focuses on LULC change dynamics (especially secondary forest succession) that occurred between 1974 and 2010 in the Błędów Desert (an area of approx. 1210 ha; a unique refuge habitat – NATURA 2000; South Poland). The methods included: photointerpretation and on-screen digitalization of KH-9 CORONA (1974), aerial orthoimages (2009) and satellite images (LANDSAT 7 ETM+, 1999 and BlackBridge – RapidEye, 2010) and GIS spatial analyses. The results of the study have confirmed the high dynamic of the overgrowth process of the Błędów Desert by secondary forest and shrub vegetation. The bare soils covered 19.3% of the desert area in 1974, the initial vegetation and bush correspondingly 23.1% and 30.5%. In the years 2009/2010 the mentioned classes contained: the bare soils approx. 1.1%, the initial vegetation – 8.7% and bush – 15.8%. The performed classifications and GIS analyses confirmed a continuous increase in the area covered by forests, from 11.6% (KH-9) up to 24.2%, about 25 years later (LANDSAT 7) and in the following 11 years, has shown an increase up to 35.7% (RapidEye 2010).
