Abstract
Multiple arterial and venous thromboses are usually related to thrombophilia or antiphospholipid syndrome. Recurrent pulmonary embolism strongly indicates the presence of genetic or acquired thrombophilic factors. Simultaneous double arterial in situ thromboses are unusual, even in thrombophilic conditions. Simultaneous occurrence of pulmonary embolism and cerebrovascular ischaemic insult are highly indicative of existence of patent foramen ovale. We present herein a patient with the double simultaneous arterial thromboses as the manifestation of thrombophilia (heterozygous for methylenetetrahydrofolate-reductase (MTHFR) C677T gene mutation). There was no patent foramen ovale suspected upon the patient’s admittance to hospital. To the best of our knowledge there have been no similar cases presented to date.
Influence of chemical composition of nanocrystalline iron’s surface on the rates of two parallel reactions: nitriding and catalytic decomposition of ammonia
Authors: Pelka Rafał , Arabczyk Walerian 
Published: October 2011

AbstractInfluence of chemical composition of nanocrystalline iron’s surface on its activity in the nitriding process of iron and catalytic decomposition of ammonia was studied. The rate of the nitriding reaction was measured by the thermogravimetric method using a tubular differential reactor. Hydrogen concentration in the reactor was also measured. The rate of the catalytic decomposition of ammonia was determined using the reactor’s mass balance. Experiments were conducted at different temperatures within the range from 300°C to 525°C. Iron catalyst for ammonia synthesis was studied. Two sorts of samples with a different content of potassium oxide (0.16 mass % and 0.64 mass % of K2O) were used. The composition of samples from the second group was modified by an addition of different amounts of sulfur. At temperatures above 400°C, when the effect of ammonia decomposition on the gas phase composition was experimentally measured, the presence of potassium and sulfur on the iron surface influenced the rate of the iron nitriding process. The ammonia decomposition rate was higher for samples with a greater amount of potassium. The rate of reactions depended also on the sulfur concentration and dropped when the sulfur content increased. The value of apparent activation energy of ammonia decomposition was in the range of 150 kJ mol−1 to 180 kJ mol−1 while the content of sulfur in the samples increased.

Published: October 2011

AbstractAcidic crude palm oil (ACPO) produced from palm oil mills with an acid value of 18 mg g−1 was considered to be a possible feedstock for biodiesel production. Due to its high acidity, conventional transesterification cannot be applied directly for biodiesel production. Methane sulphonic acid (MSA, CH3SO3H) is used to reduce the acidity prior to the alkaline transesterification reaction. The laboratory-scale experiments involved an MSA to ACPO dosage of 0.25–3.5 %, a molar ratio (methanol to ACPO) from 4: 1 to 20: 1, reaction temperature of 40–80°C, reaction time of 3–150 min, and stirrer speed of 100–500 min−1. The optimum esterification reaction conditions were 1 % of catalyst to ACPO, with a molar ratio of methanol to ACPO of 8: 1, a stirring speed of 300 min−1, for 30 min and at 60°C. Under these conditions, the FFA content was reduced from 18 mg g−1 to less than 1 mg g−1 and with a yield of 96 %. The biodiesel produced met the EN14214 standard specifications. MSA was recycled for three times without losing its activity. The biodiesel produced in a two-stage process has a low acid value (0.14 mg g−1).
The use of stable isotopes ratios for authentication of fruit juices
Authors: Magdas Dana , Vedeanu Nicoleta , Puscas Romulus 
Published: October 2011

AbstractThe determination of the content of stable isotopes, 18O and 2H, respectively, in juice water facilitates the distinction between authentic juices and juices made from concentrates by redilution with tap water. At the same time, the detection of C4 cane or corn-derived sugar syrups in fruit juices which are produced from C3 fruit types is thus facilitated by the characteristic differences in 13C/12C, expressed as δ 13C (‰) values due to photosynthetic CO2 assimilation via the C3−, C4−, and crassulacean acid metabolism pathways. In this study, the quantitative determination of water added to an authentic juice, on the basis of δ 18O, and δ 2H values, respectively, was successfully performed. Also, the δ 18O, and δ 2H of juice water and δ 13C of the whole juice in 18 samples were also determined. The results obtained provided us with the possibility of distinguishing between authentic fruit juices and those obtained by redilution of concentrated fruit juices and the detection of C4 type added sugar.

Published: October 2011

Abstract
The results of measurements of suspended sediment and bed load carried by the Kacza River into the Gulf of Gdańsk are discussed. The investigations were conducted in the years 2009–2010 at the Orłowo transect and at the mouth of the Kacza River in the Gulf of Gdańsk. The research has shown that the Kacza River discharged about 673 tons of sediment annually to the Gulf of Gdańsk, with 77% being transported as bed load. The granulometric composition of the river load is dominated by coarse-grained sand fractions.
Inventory of the taxonomical composition of the plankton ciliates in the Curonian Lagoon (SE Baltic Sea)
Authors: Grinienė Evelina , Mažeikaitė Stasė , Gasiūnaitė Zita 
Published: October 2011

Abstract
Species composition of plankton ciliates was studied in the Curonian Lagoon in 2007–2008 and compared to long term investigations dating back to the 1980th. In total, 152 taxa were identified at the level of species or genera. More species (76 species/higher taxa) was found in the estuarine part of the Lagoon due to temporally unstable salinity and the presence of both freshwater and brackish/marine species. Some of the brackish/marine species: Tintinnopsis baltica, Tintinnopsis kofoidi, Cothurnia maritima, Lohmaniella oviformis, Lohmaniella spiralis and Helicostomella subulatum were recorded for the first time in the lagoon. The ciliate community at the freshwater sites was less diverse, containing 63 species/higher taxa in the central stagnant part of the Lagoon and 47 — in the Nemunas River avandelta. The comparison of present and past studies revealed that the use of a single live-counting method could lead to underestimation of small nanociliate species, whereas examination of Lugol fixed material provides relatively poor taxonomic information.
Diet composition of herring (Clupea harengus L.) and cod (Gadus morhua L.) in the southern Baltic Sea in 2007 and 2008
Authors: Dziaduch Diana 
Published: October 2011

Abstract
Diet composition of two commercial fish species, herring and cod, were studied in some regions (mainly Gda’nsk and Bornholm Basins, and the Polish coast) of the southern Baltic Sea in 2007 and 2008. Herring is the dominant zooplanktivorous species in the ecosystem of the Baltic Sea, but apart from mesoplanktonic organisms it also eats macroplanktonic and benthic species in considerable amount. The diet of cod consists of fish and crustaceans from pelagic, hyperbenthic and benthic habitats. The feeding preferences of fish indirectly reflect changes in the whole food chain in the Baltic Sea. This research focuses specifically on these invertebrate species, which are eliminated from the environment by most of the ichthyofauna of this region. The aim of this research is to examine the role of invertebrate organisms belonging to Crustacea in the diet of herring and adult cod to supply updated results about feeding of these fish as little data have been collected since the 1990s. The present study is a preliminary survey and results can not be considered conclusive. The restricted numbers of analyzed stomachs of fish and selected seasons of the year addressed in this paper are a starting point for further studies with a larger scope. In this study, 20 to 90% of herring had empty stomachs. Mesozooplankton dominated the diets of small and large herring. Mysidacea, which were historically important prey for herring, are now scarce and have been replaced by planktonic Amphipoda. In the case of cod, consumption of Mysidacea has never been as low as in this study. As for other invertebrate prey, the benthic isopod Saduria and Crangon shrimp achieved the highest amount by number and weight. These results show distinct changes in diet when compared to previous investigations and require verification at a larger spatial scale.
Domesticating Socialism and the Senses in Jane Hume Clapperton'sMargaret Dunmore: Or, A Socialist Home
Authors: Parkins Wendy 
Published: October 2011

Domesticating Socialism and the Senses in Jane Hume Clapperton's Margaret Dunmore: Or, A Socialist HomeClapperton's utopian novel, Margaret Dunmore: Or, A Socialist Home (1888), provides a good example of the way in which matters of everyday life – food, childcare, the home – were increasingly implicated in agendas for social transformation in the fin-de-siècle period, and seen as problems that could be solved by modernity. The varying programmes for change offered by socialists and feminists in this period, however, could reflect sharply divergent views of the pleasures and politics of everyday life, and Clapperton's novel assumes a disparity between ‘social happiness’ and the sensory experience of the individual that warrants examination. Beginning with an overview of Clapperton's theory of ‘conscious’ evolution which takes the home as the locus of social transformation, this essay will focus on the place of the senses and emotions in Margaret Dunmore, written to exemplify Clapperton's political philosophy of ‘Scientific Meliorism’ which combined socialism and feminism with evolutionary and eugenic theory. In this novel, the individual's sensory experience poses a threat to the well-being of the ideal community. Unlike emotions, which Clapperton depicts as amenable to conscious adaptation through a combination of social correction and self-scrutiny, sensory experience is inherently anti-social, immune to the claims of service to others which was crucial to Clapperton's understanding of socialism. From childcare to cooking, forms of sensory deprivation are heralded as the key to efficiently resolving the disorder or conflict caused by over-stimulation or self-indulgence. As a result, despite Clapperton's emphasis on the ‘evolution of happiness’, the value placed on rationality, technology, and self-control over convivial pleasures means that the constrictions and inequities of bourgeois domesticity are merely reconfigured rather than abolished.
Technique et cinématique. Sur les fondements épistémologiques de la fusion de la réalité et de la fiction au XXe siècle
Authors: Giroux Dalie 
Published: October 2011

Résumé Martin Heidegger entrevoit deux maux liés à la contraction de l’espace et du temps induite par la technique moderne. Le premier est que la recherche de représentations exactes du monde découle d’une conception subjectiviste de la perception qui transforme les humains et les choses en purs objets. Le deuxième mal relève du fait que la pro-vocation est un mode de dévoilement qui, en se produisant, occulte le fait qu’elle est un mode de dévoilement et, par extension, occulte le fait qu’elle est dans un processus d’occultation. Comment cette occultation se produit-elle, et quel est le sens d’une entreprise philosophique de dévoilement de ce qui est occulté ? Le concept de mimétisme permettra dans ce texte, sous le mode du dégrisement, de rendre compte des différents aspects du mécanisme d’occultation propre à la technique moderne.
Le sacré et le fan. Étude sur l'univers science-fictionnel de Star Wars
Authors: Vincent Frédéric 
Published: October 2011

Résumé Cet article se propose de comprendre la manière dont un univers science-fictionnel comme Star Wars s’articule dans la réalité sociale. L’individu qui s’aventure sur les traces de Luke Skywalker se laisse envahir par un imaginaire initiatique qui vient considérablement bouleverser sa manière d’être dans le monde : la rencontre avec le héros exemplaire est une ouverture au sacré qui participe à la construction sociale de l’individu. Ce qu’il convient de déterminer également, c’est l’intentionnalité du fan à travers certaines pratiques sociales comme le ciné-tourisme ou le cosplay.
Jorge Luis Borges et la dédalographie. Introduction fictionnelle à un archétype spatial
Authors: Bello Marcano Manuel 
Published: October 2011

Résumé Le labyrinthe est une référence récurrente dans l’imaginaire spatial de la postmodernité. Il est un système d’organisation spatiale chaotique et codifié qui se nourrit de l’erreur. Nous habitons la ville contemporaine comme un labyrinthe. Or, en tant que pulsion urbaine, cet archétype spatial nous permet d’aller de la fiction littéraire à la « friction » sociale. Dans un court récit, J. L. Borges analyse les conditions psychologiques de celui qui a un labyrinthe pour demeure. La demeure d’Astérion raconte le quotidien d’un monstre dans un espace où il se sent chez lui. Au travers de la fiction borgésienne, comment comprendre ce passage de l’archétype spatial vers la condition cosmique, voire cosmétologique, de l’habitat urbain contemporain ?
Finitely Related Algebras In Congruence
Distributive Varieties Have Near Unanimity
Terms
Authors: Barto Libor 
Published: October 2011

Abstractwe show that every finite, finitely related algebra in a congruence distributive variety has a near unanimity term operation. as a consequence we solve the near unanimity problem for relational structures: it is decidable whether a given finite set of relations on a finite set admits a compatible near unanimity operation. this consequence also implies that it is decidable whether a given finite constraint language defines a constraint satisfaction problem of bounded strict width.
An Evaluation of the Impact of a Social Inclusion Programme on Occupational Functioning for Forensic Service Users
Authors: Fitzgerald Martin 
Published: October 2011

Introduction: The rehabilitation of forensic service users with serious mental illness is an emerging specialism in occupational therapy. However, there is little evidence to support the development of this role. Government white papers and guidelines recommend a rehabilitation process that involves a social inclusion agenda and the literature supports the role of the occupational therapist in its provision. This study was designed to provide evidence for, and to guide, the practice of forensic occupational therapists working in a rehabilitation setting. Method: The study compared Model of Human Occupation Screening Tool (MOHOST) scores of forensic service users who received treatment as usual and participated in a social inclusion programme (n = 24) with the scores of those who received treatment as usual (n = 19) only. Results: Although no difference was found in MOHOST scores between the two groups before intervention (p>0.05 at 0.493), a significant difference in scores was found in the intervention group post-intervention (p<0.05 at 0.006). This difference is hypothesised to represent change in occupational functioning and evidence of successful treatment outcomes. Conclusion: The study concluded that forensic service users could benefit from occupational therapy programmes that include activities to promote social inclusion.
Facilitation of Research-Based Evidence within Occupational Therapy in Stroke Rehabilitation
Authors: Kristensen Hanne Kaae , Borg Tove , Hounsgaard Lise 
Published: October 2011

Purpose: This study investigated the facilitation of evidence-based practice with the use of everyday life occupations and client-centred practice within occupational therapy in three settings of stroke rehabilitation. Method: The study was based on a phenomenological hermeneutical research approach, and inspired by participatory action research methods. Participant observations, focus group discussions and individual interviews took place over a period of 20 months. Text interpretation, developed by Ricoeur, was used in data analysis. Findings: The key role of the facilitator in the implementation of evidence-based practice as a change process was stressed. During the implementation, it was crucial that the therapists as a group had the opportunity to discuss local practice knowledge, and to appraise the knowledge use critically, in order to develop their practice knowledge and new skills adapted to local contexts. The implementation resulted in various new working routines. Learning processes became part of developing the occupational therapists' professional identities, expressed in more professional confidence. Collaboration in the organisation of the implementation process was significant. Conclusion: The main findings indicated that the use of participatory action research methods and theory of situated learning interacting with the Promoting Action on Research Implementation in Health Services framework provided useful perspectives and structures for the investigation of the implementation of evidence-based occupational therapy.

Published: October 2011

Aim: This study compared the stress distributions of endodontically treated tooth restored with carbon and titanium post during different loading conditions.
Methodology: A 3-dimensional finite element model was created to represent an endodontically treated maxillary central incisor tooth with its supporting structures. Stress distribution and stress values were then calculated by considering the three dimensional von Mises stress criteria.
Results: A 100-N static vertical occlusal load was applied on the node at the center of occlusal surface of the tooth. The von Mises stress values for carbon post model was on the coronal third and the cervical area of the root in the range of 353.149 and 13.878 MPa, for titanium post model was 540.736 and 22.777 MPa.
Conclusion: This study shows that the titanium post yields larger stresses than the carbon post.

Published: October 2011

AbstractObjectiveTo examine the relationship between pain, radiographic severity, and a common set of co‐occurring centrally‐mediated symptoms (fatigue, sleep quality, and depression) in women with knee osteoarthritis.MethodsParticipants underwent knee radiographs, and had repeated assessments of pain severity and other centrally‐mediated symptoms during a 5‐day home monitoring period. To examine associations between pain severity (the average of pain over the home monitoring period), measures of osteoarthritis radiographic severity (Kellgren/Lawrence grade, minimum joint space width), centrally‐mediated symptoms, and demographics (age) were used. Symptoms of fatigue, sleep efficiency, and depression were used in a composite measure representing centrally‐mediated symptoms.ResultsUsing a series of linear regression models in which each variable was entered hierarchically (n = 54), the final model showed that 27% of the variance in pain severity was explained by age, radiographic severity, and centrally‐mediated symptoms. Centrally‐mediated symptoms explained an additional 10% of the variance in pain severity after the other 2 variables were entered.ConclusionBoth radiographic severity and centrally‐mediated symptoms were independently and significantly associated with pain severity in women with knee osteoarthritis. In addition to more severe radiographic features, women with higher centrally‐mediated symptoms had greater pain severity. Treatments for women with symptomatic knee osteoarthritis may be optimized by addressing both peripheral and central sources of pain.

Published: October 2011

AbstractArrays of nanowires are fabricated with alternating segments of the magnetostrictive alloy Fe1–xGax and Cu using electrochemical deposition in nanoporous anodic aluminium oxide (AAO) templates. The difficult nature of Ga‐alloy electrochemistry is overcome by controlling mass‐transfer and hydrodynamic conditions using novel rotating disk electrode templates to obtain highly uniform segment lengths throughout the arrays. Extensive structural characterization by XRD, EBSD and TEM reveals a strong <110> textured Fe1–xGax growth. Furthermore, using vibrating sample magnetometry (VSM), we demonstrate that control of magnetization reversal processes is possible once uniform aspect ratios are obtained for both the Fe–Ga and Cu segments.
Antimicrobial activity of novel aminated chitosan derivatives for biomedical applications

Published: October 2011

AbstractThis study concerns the improvement in the antimicrobial activity of new aminated chitosan derivatives. p‐Benzoquinone (PBQ) conjugated chitin was first prepared and then reacted with ethylenediamine (EDA) to get aminated chitin. The latter was finally deacetylated to get new aminated chitosan derivatives. Factors affecting conjugation and amination steps were studied. The amination process was confirmed by using FT‐IR, TGA analysis, and the solubility test. The new aminated chitosan derivatives show a higher solubility, almost double, at a pH ranging from 5 to 6 compared with z pristine chitosan. The antibacterial activity of the chitosan derivatives was tested against four different bacterial strains: two Gram‐negative (Escherichia coli and Pseudomonas aeruginosa) and two Gram‐positive (Bacillus cereus andStaphylococcus aureus). It was found that the antibacterial activity of the chitosan derivatives is better than those of chitosan and increases with the increasing amount of introduced amine groups. Furthermore, the cytotoxicity test using the Caco 2 cell line shows a moderate safety level for the new aminated chitosan derivatives. Chitosan derivatives show potential bactericidal activity against all strains examined especially against Gram‐negative bacteria (E. coli and P. aeruginosa). For Gram‐positive bacteria, chitosan derivatives killed 93% of B. cereus and 92% of S. aureus, compared with 44% and 85% for chitosan after 3 and 5 h, respectively. © 2011 Wiley Periodicals, Inc.
