Abstract
The aim of the presented study was to determine whether pulmonary barotrauma without pneumothorax affects the parameters of acid-base balance. The experiment was conducted on rabbits divided into experimental and control groups. The animals from the experimental group were subjected to compression in the hyperbaric chamber and pulmonary barotrauma was induced using a method developed by authors. The arterial blood was sampled before the experiment, after anaesthesia and intubation, after injury, and after treatment (in the group undergoing hyperbaric therapy). All parameters of acid-base balance were found to be within the reference ranges. Since the biggest changes were observed after anaesthesia and intubation and not after the injury, it was concluded that pulmonary barotrauma had no significant effect on the parameters of acid-base balance.

Abstract
The purpose of the study was to evaluate the effects of intrathecal (IT) ketamine HCl anesthesia on clinical values and some haemodynamic and biochemical parameters in bitches. An IT ketamine (10 mg/kg) was administered to 30 bitches with a spinal needle (18-22 G) in the lumbosacral space. The haemodynamic parameters were monitored and some biochemical values were assessed (blood gase, oxygen-haemoglobin, and electrolyte levels). The length and depth of anaesthesia was determined with a pinprick test, touching to the ligamenta lata uteri and incision. Anaesthesia took effect in less than 1 min in all dogs and has lasted an average of 95.9 min. In spite of the fact that the dogs recovered completely from the effects of dissociative anaesthesia, the anaesthesia in the some extremities was observed to be continued for an average of 17 min longer. The use of IT ketamine HCl raised blood pressure and did not have a depressive effect on respiratory and cardiac functions. It was concluded that ketamine HCl could be an appropriate alternative for ovariohysterectomy operations in bitches when the quality of the anaesthesia and the prevention of bradycardia and hypotension are considered.

Published: February 2013

Abstract
The molecular epidemiological relationship among isolates of Salmonella enterica serovar (S.) Saintpaul, which was identified in animals, food, and humans in several EU countries, was investigated. Pulsed-field gel electrophoresis (PFGE) revealed a high degree of genetic diversity (82 XbaI PFGE profiles with 42.6% similarity) among 159 S. Saintpaul isolates from animals (n=91), food of animal origin (n=29), and humans (n=36) in 12 European countries during 2005 to 2009. Most frequent profiles (n=12) comprised almost 50% of the tested isolates. Profiles obtained in isolates from a single source within a particular geographical region or particular period of time were indistinguishable or closely related. Turkeys were confirmed as the major reservoir for S. Saintpaul. Indistinguishable PFGE profiles were identified in up to 19 isolates from turkey breeding and fattening flocks and food over the study period. Other animals, including food and pets, may also contribute to S. Saintpaul spread. International trade of animals and food, as well as travelling contributes to the spread of a specific clone to different geographical areas. Although control programmes in breeding turkey flocks, together with improved biosecurity, may interrupt the major transmission routes, it was concluded that S. Saintpaul will continue to represent a potential threat to human health.

Abstract
The aims of this study were estimation of thyroxin status in dogs infected with B. canis, and determination of the association between azotaemia and concentrations of total thyroxin (TT4) and free thyroxin (FT4) in canine babesiosis. Concentrations of TT4 and FT4 were determined using an immunoassay in 23 dogs infected with B. canis (nine azotaemic dogs and 14 non-azotaemic dogs). Mann-Whitney U test was used to compare the concentrations of TT4 and FT4 in groups of azotaemic and non-azotaemic dogs. Correlations between azotaemic parameters (i.e. serum urea and creatinine) and TT4 and FT4 concentrations were calculated. The obtained results showed high prevalence of dogs infected with B. canis showing decreased TT4 and FT4 concentrations. No difference between concentrations of TT4 and FT4 in azotaemic and non-azotaemic dogs was demonstrated, but statistically significant correlations between the level of TT4 and FT4 and serum levels of urea and creatinine were shown.

Published: February 2013

Abstract
Morphological changes developed in rat bucal mucosa, parotid glands, and lymphoid nodes following 6 weeks exposure to dental acetal resin implants were compared to metal/titanium, acrylic implants, and sham-operated rats. Morphological evaluation of bucal mucosa of rats exposed to acetal resin showed an increased accumulation of lymphoid and macrophage-like cells compared to sham-operated rats. Eosinophils were found in bucal mucosa and in parotid glands of rats exposed to acetal resin, although this change did not differ significantly from sham-operated rats. Morphological findings with respect to granular reaction and proliferation were similar in acetal resin exposed and sham-operated rats. Acetal resin implants may induce inflammatory and potentially allergic reactions at the site of implantation.
Conditions of Poland’s foreign and security policy within the EU and NATO environment
Authors: Antczak- Barzan Anna 
Published: February 2013

AbstractThe article is an attempt to answer the question about the state of Poland’s security after the first decade of the twenty-first century, what are its determinants, what kind of challenges Poland faces and which of them may turn into a threat and which into an opportunity, or what Polish potential is and which of its components determine its position on the international arena. It is achieved through a detailed analysis of actions undertaken by Poland in the international arena to strengthen its international position as well as the level of its security. Thus, the aim is to identify those determinants which may contribute to establishing a stronger position and which can create problems and become a formidable challenge in the context of various aspects of security, and even develop into a threat. Unfortunately, the picture which comes out of the above mentioned analysis is not optimistic and the impression is that Poland did not use the chance it was given after the accession to the NATO and the EU.
Dilemmas of mineral resources use in selected economic theories
Authors: Krzak Mariusz 
Published: February 2013

Streszczenie
Rozwój cywilizacji człowieka napędza popyt na różnego rodzaju zasoby naturalne. Obecnie obejmuje on nie tylko kopaliny mineralne, glebę, wodę, powietrze, florę czy faunę, lecz także siły przyrody i inne walory środowiska, determinujące jakość życia człowieka, takie jak: przestrzeń geograficzna, krajobraz, mikroklimat i in. Spomiędzy tak wielu odmiennych kategorii zasobów naturalnych okazuje się, że bogactwa mineralne, w zdecydowanej większości nieodnawialne, mają często decydujący wpływ na poziomu dobrobytu. W teorii eksploatacji zasobów naturalnych wypracowano dotychczas szereg różnych modeli, które - najczęściej w sposób dynamiczny (uwzględniając czynnik czasu) - maksymalizują wielkość społecznego dobrobytu implikowanego korzystaniem z zasobu.
W artykule, przypominając wybrane, ugruntowane teorie ekonomiczne, poruszono problematykę użytkowania i ochrony nieodnawialnych zasobów kopalin mineralnych na etapie ich gospodarczego użytkowania. Wykorzystując teorię rozwoju trwałego, model Hotellinga i jego późniejsze modyfikacje uwypuklono trudności realizacji polityki w zakresie ich ochrony. Przybliżono spojrzenia na koncepcję użytkowania zasobów mineralnych w świetle N-osobowego dylematu więźnia. Rozważania zobrazowano prostymi przykładami, realizując je przy założeniu braku doskonałego, nieograniczonego substytutu.
Potential for increasing oil Recovery from Polish oil-fields by applying EOR methods / Analiza Możliwości Zwiększenia Efektywności Wydobycia Ropy Naftowej Z Polskich Złóż W Oparciu Metody Eor
Authors: Wojnarowski Paweł 
Published: February 2013

Streszczenie
Jednym ze sposobów zwiększenia efektywności wydobycia ropy naftowej jest zastosowanie zaawansowanych metod wydobycia (EOR - Enhanced OilRecovery). W odróżnieniu od pierwotnych i wtórnych metod wydobycia, celem metod zaawansowanych jest dostarczenie do złoża dodatkowego źródła energii wspomagającego naturalne procesy lub je zastępującego, a także modyfikacja składu i właściwości fizycznych płynów złożowych w celu minimalizacji oporów przepływu w złożu. Metody te znajdują szczególnie zastosowanie w przypadku złóż w znacznym stopniu sczerpanych. Znaczenie tych metod w światowym wydobyciu rośnie, a dominującą rolę zaczynają odgrywać metody zatłaczania gazów w tym dwutlenku węgla. Polskie złoża ropy naftowej są obecnie eksploatowane z wykorzystaniem metod konwencjonalnych, co stwarza możliwości podniesienia efektywności wydobycia przez zastosowanie metod zaawansowanych. Proces doboru optymalnej metody do złoża jest złożony i wieloetapowy. W fazie wstępnej opiera się na podstawowych informacjach o złożu i stopniowo przechodzi do etapów zaawansowanych, kończących się opracowaniem szczegółowego projektu najefektywniejszej metody. W pracy przeanalizowano możliwości zastosowania tych metod na polskich złożach wykorzystując technikę opartą na podstawowych kryteriach ich stosowalności i logikę dwuwartościową. Przeanalizowano 49 złóż ropy naftowej z całego obszaru Polski występujących zarówno w skałach węglanowych jak i piaskowcowych. Z punktu widzenia kryteriów stosowania metod EOR, analizowane obiekty to złoża ropy o średniej gęstości i lepkości, niskiej przepuszczalności (w przypadku skał węglanowych podwójna porowatość), zalegające stosunkowo płytko lub na średniej głębokości. Uzyskane wyniki wskazują, że najszersze zastosowanie w warunkach polskich znaleźć mogą metody zatłaczania gazów, w tym dwutlenku węgla lub azotu. Wymaga to jednak przeprowadzenia szeregu badań i testów pilotażowych, gdyż doświadczenia amerykańskie nie mogą być bezpośrednio przenoszone ze względu na odmienne warunki złożowe, technologiczne i ekonomiczne.
Experimental analysis of contract net protocol in multi-robot task allocation
Authors: Liekna Aleksis , Lavendelis Egons , Grabovskis Arvids 
Published: February 2013

Abstract
- This paper focuses on the experimental analysts of Contract NET protocol for Multi-Robot task allocation. The problem domain consists of multiple vacuum cleaning robots that need to cooperate for cleaning an area that is beyond the capabilities of a single robot. A robot simulator has been used to experiment with various area and robot locations, and the summary of the effort required to process the tasks has been recorded. Experimental results show that using Contract NET protocol alone is not sufficient to achieve optimal results in task allocation. A more advanced strategy with or without involving the Contract NET protocol is required. Possible strategies are outlined and their analysis is the subject of the future work.
Conscious Inclusion of Women Musicians
Authors: Cartwright Joan 
Published: February 2013

Abstract
This paper discusses the vast divide between performance opportunities and income earned by male and female musicians. Although female singers are quite visible on the world’s stages, few female instrumentalists are employed on a regular basis and even fewer women composers have their music commissioned for programs or films funded by private and public monies. Several proficient female jazz musicians are identified, and how and why women are omitted from performance is discussed. The need for everyone-producers, promoters, funders, and bandleaders-to consciously choose to include women musicians in programming, especially where public funding is involved, is emphasized.
“Contending with the Fretful Element”: Shakespeare and the (Gendered) Great Chain of Being
Authors: Szönyi György E. 
Published: February 2013

Abstract
E. M. W. Tillyard’s short but seminal book, The Elizabethan World Picture made its appearance as a ground-breaking work in the mid-1940s. It successfully adapted Arthur O. Lovejoy’s discovery of the Great Chain of Being as the central idea and metaphor of the premodern world picture for English Renaissance culture and literature, offering a key to understanding the often unfamiliar and obscure natural philosophy and metaphysics behind its works of art and literature. The concept of the Great Chain also led to Shakespeare being seen as a supporter of a conservative order in which religious, moral, philosophical, and scientific notions corresponded with each other in a strict hierarchy. The poststructuralist turn unleashed a severe attack on Tillyard and his legacy. As Ewan Fernie in a recent book on the Renaissance has diagnosed: “Now, after the theoretical overhaul, the notion of an ultimately authoritarian Renaissance has been thoroughly revised. In place of Tillyard’s full-fledged and secured physical, social and cosmological system, more recent critics tend to posit a conflicted and constantly negotiated culture with no essential pattern”. But what has happened to the idea of the Great Chain of Being, which, without doubt, played a major role in the Renaissance world picture and provided a basic knowledge about the elements? In my paper I am going to revisit some aspects of this world picture and examine how Shakespeare related to this (more often than not) in a subversive way, while still remaining within the boundaries of this organic and proto-modern system. Since the concept of the elements had gender aspects, too, I will also focus on the question of how proto-modern natural philosophy theorised about the dichotomy, antagonism, and the cooperation of male and female principles.
Ladies and Gentlemen in Renaissance Western Europe Eros via Thanatos
Authors: Zelinka Elisabeta 
Published: February 2013

Abstract
The present article offers a postmodern (re)interpretation of the 16th century Renaissance set of social etiquettes versus the average citizen’s Weltanschauung triggered by his most natural drives and impulses. The epicentral focus of our investigation is the social network(s) built by the different, sometimes oppositional ethical, theological and epistemological codes. What types of motivation triggered certain members of different social layers to observe or to break these codes? Was there any differentiation between clergymen and (fe)male aristocracy? Most importantly, why was the epistemological positionality of men different from that of (educated) women?
Is it a He or a She? Gender Differences in Italian Translations of Oscar Wilde’s Stories for Children
Authors: Coles Rowena 
Published: February 2013

Abstract
This paper examines how the gender of personification is affected in Italian translations of Oscar Wilde’s children’s stories. It shows how the conflict between natural and grammatical gender may be problematic for the translator and reveals how Italian children, who believe they are reading a text identical to the original, are in fact reading a somewhat different story.
Metaphors of Hegemonic Masculinity – Women’s Understanding of Sport Metaphors in Political Discourse
Authors: Radić-Bojanić Biljana , Silaški Nadežda 
Published: February 2013

Abstract
Within the framework of Conceptual Metaphor Theory (Lakoff and Johnson 1980) and Critical Discourse Analysis (van Dijk 1993, Wodak 2006) we analyse in this paper the results of a survey conducted among 100 women and 20 men in order to establish the level of their understanding of sport metaphors in political discourse. The results indicate that sport metaphors may pose a serious barrier to women’s understanding of political life and may discourage women’s political participation.

BackgroundBack School and McKenzie methods are popular active treatment approaches that include both exercises and information for patients with chronic nonspecific low back pain.ObjectiveThe purpose of this study was to compare the effectiveness of Back School and McKenzie methods in patients with chronic nonspecific low back pain.DesignThe study was a prospectively registered, 2-arm randomized controlled trial with a blinded assessor.SettingThe study was conducted in the outpatient physical therapy clinic in São Paulo, Brazil.PatientsThe study participants were 148 patients with chronic nonspecific low back pain.InterventionsThe 4-week treatment program (one session/week) was based on the Back School (delivered to the group) or McKenzie (delivered individually) principles. The participants also were instructed to perform a daily set of home exercises.MeasurementsClinical outcomes were assessed at follow-up appointments at 1, 3, and 6 months after randomization. Primary outcome measures were pain intensity (measured by the 0–10 pain numerical rating scale) and disability (measured by the 24-item Roland-Morris Disability Questionnaire) 1 month after randomization. Secondary outcome measures were pain intensity and disability at 3 and 6 months after randomization, quality of life (measured by the World Health Organization Quality of Life–BREF instrument) at 1, 3, and 6 months after randomization, and trunk flexion range of motion measured by an inclinometer at 1 month after randomization. The data were collected by a blinded assessor.ResultsParticipants allocated to the McKenzie group had greater improvements in disability at 1 month (mean effect=2.37 points, 95% confidence interval=0.76 to 3.99) but not for pain (mean effect=0.66 points, 95% confidence interval=−0.29 to 1.62). No between-group differences were observed for all secondary outcome measures.LimitationsIt was not possible to monitor the home exercise program. Therapists and participants were not blinded.ConclusionsThe McKenzie method (a more resource-intensive intervention) was slightly more effective than the Back School method for disability, but not for pain intensity immediately after treatment in participants with chronic low back pain.
Fabrication and characterization of regenerated silk scaffolds reinforced with natural silk fibers for bone tissue engineering

Published: February 2013

AbstractWe introduce a novel Bombyx mori silk‐based composite material developed for bone tissue engineering. Three‐dimensional scaffolds were fabricated by embedding of natural degummed silk fibers in a matrix of regenerated fibroin, followed by freeze‐drying. Different ratios of fibers to fibroin were investigated with respect to their influence on mechanical and biological properties. For all scaffold types, an interconnected porous structure suitable for cell penetration was proven by scanning electron microscopy. Compressive tests, carried out in static and cyclic mode under dry as well as wet conditions, revealed a strong impact of fiber reinforcement on compressive modulus and compressive stress. Cell culture experiments with human mesenchymal stem cells demonstrated that the fiber/fibroin composite scaffolds support cell attachment, proliferation, as well as differentiation along the osteoblastic lineage. Considering the excellent mechanical and biological properties, novel fiber/fibroin scaffolds appear to be an interesting structure for prospect studies in bone tissue engineering. © 2013 Wiley Periodicals, Inc.

An evaluation of three sampling methods to monitor a digenetic trematode Centrocestus formosanus in a spring-fed ecosystem
Authors: CANTU VALENTIN , BRANDT THOMAS M. , ARSUFFI THOMAS L. 
Published: February 2013

SUMMARYCentrocestus formosanus is a digenetic trematode from Asia that parasitizes multiple hosts and is a concern in the Comal River, Texas, USA, because of its negative effects on the endangered fountain darter Etheostoma fonticola. To determine a practical sampling method to monitor C. formosanus in the Comal River, we evaluated three sampling methods using wild-caught fish, caged fish reared in the laboratory, and cercariometry. Cercariometry detected significant spatial and temporal patterns of cercarial density in river water that were similar with metacercarial intensity in caged fish, but inconsistent with metacercarial intensity in wild-caught fish. Our results also showed a positive correlation between cercarial density in river water and metacercarial intensity in caged fish. Conversely, the relationship was not significant between cercarial density and metacercarial intensity in wild-caught fish. Because cercariometry predicted similar trends with the caged fountain darter sampling method, cercariometry was useful in predicting C. formosanus gill infections, infection rate, and longevity in infected fountain darters. Although trends from cercariometry and caged fish sampling methods were similar, we recommend cercariometry because it was less expensive to use given the amount of sampling effort required and provides trends that can be used to make pro-active management decisions in C. formosanus-infested aquatic ecosystems.
Asymptotic formulas for coefficients of Kac–Wakimoto Characters
Authors: BRINGMANN KATHRIN , MAHLBURG KARL 
Published: February 2013

AbstractWe study the coefficients of Kac and Wakimoto's character formulas for the affine Lie superalgebrassℓ(n+1|1)∧. The coefficients of these characters are the weight multiplicities of irreducible modules of the Lie superalgebras, and their asymptotic study begins with Kac and Peterson's earlier use of modular forms to understand the coefficients of characters for affine Lie algebras. In the affine Lie superalgebra setting, the characters are products of weakly holomorphic modular forms and Appell-type sums, which have recently been studied using developments in the theory of mock modular forms and harmonic Maass forms. Using our previously developed extension of the Circle Method for products of mock modular forms along with the Saddle Point Method, we find asymptotic series expansions for the coefficients of the characters with polynomial error.
