Published: March 2014

Abstract
The undertaken study aimed at analysing the effect of linseed oil used in diets for turkey hens on contents of pro- and antioxidants in their tissues. Additionally, correlations were analysed between the contents of these compounds in blood, liver, and muscles of the birds. The experiment was conducted on 240 one-week-old turkey hens reared until 16 weeks of age, randomly allocated into two feeding groups. Hens from the first group received soybean oil in their complete feed mixture, whereas linseed oil was the source of fat for turkey hens from the second group. The oil content of the diet was on the level appropriate for the period of feeding: Starter - 0.5%; Grower I - 1.0%, Grower II - 2.5%; Finisher I - 3%. The redox parameters were assayed in breast and thigh muscles, blood, and liver. Introduction of PUFA n-3 high linseed oil to a feed mixture contributed to the enhancement of lipid peroxidation processes, which was indicated by a significant increase in concentrations of H2O2 and malondialdehyde in muscles, and by an increase of superoxide dismutase activity and concentrations of vitamin C and minerals (Cu+2, Zn+2, Fe+2, Se+2). This points out the need of strengthening the antioxidative defence by the use of suitable antioxidants. The use of linseed oil as a feed material for turkey hens additionally contributed to changes in parameters determining the ferric reducing ability of plasma (FRAP). The increased FRAP values resulted from a significant increase in vitamin E level.
Assessment of CD11b and CD11/18 integrin expression on leukocytes of dogs with atopic dermatitis
Authors: Taszkun Iwona 
Published: March 2014

Abstract
Cytometric analysis was performed in order to detect the expression of surface molecules CD11b and CD11/18 on lymphocytes, granulocytes, and monocytes of peripheral blood of dogs with atopic dermatitis (AD) complicated by purulent dermatitis. The percentage of peripheral blood lymphocytes with CD11b and CD11/18 was found to be significantly higher (P < 0.05) in dogs with AD than in healthy dogs. The percentage of granulocytes expressing CD11b molecule was significantly lower in dogs with complicated AD compared to healthy dogs and dogs with uncomplicated AD. The expression of CD11b and CD11/18 integrin on monocytes of dogs with complicated AD depended on the severity of symptoms and was higher in dogs with deep purulent dermatitis. It was concluded that the expression of CD11b and CD11/18 integrin on leukocytes of dogs with AD depends on the stage of the disease.

Abstract
The study aimed to demonstrate the expression of hypoxia-inducible factor (HIF-1α) in soft tissue mesenchymal tumours (fibroma and fibrosarcoma) in dogs. An attempt was made to correlate the obtained results with density of blood vessels (expression of von Willebrand Factor, vWF), expression of Ki-67 proliferation antigen, and with intensity of apoptosis in studied tumours. The study was performed on paraffin sections of 15 fibromas and 40 fibrosarcomas sampled from 55 female dogs aged 6 to 16 years. Immunohistochemical staining against HIF-1α, vWF, and Ki-67 was performed. Apoptosis was detected with the use of TUNEL reaction. A significantly higher HIF-1α expression was noted in fibrosarcomas in comparison to fibromas (P < 0.0001). HIF-1α expression in fibromas manifested strong positive correlation with tumour vascularity (r = 0.67, P = 0.007). Moreover, HIF-1α expression in fibrosarcomas manifested a moderate positive correlation with tumour malignancy grade (r = 0.44, P = 0.004), tumour vascularity (r = 0.52, P < 0.001), Ki-67 antigen expression (r = 0.42; P = 0.007), and TUNELpositive cells (r = 0.37, P = 0.017). Expression of HIF-1α was detected in 86.7% of fibroma type tumours and in 100% of fibrosarcomas. In all studied tumours expression of HIF-1α manifested positive correlation with the density of blood vessels, and in fibrosarcomas it correlated also with malignancy grade, intensity of Ki-67 expression, and with intensity of apoptosis in tumour cells.

Abstract
The aim of this study was to investigate the usefulness of new software Pixel Flux (PXFX) for clinical evaluation of tissue perfusion in the field of reproduction in dogs. The experiment was performed on six adult Beagle dogs. Different organs and tissues of the animals were examined with the MyLab25 Gold ultrasound system. Blood flow in the ovary, testicle, prostate, the ramification of the penile artery, and the network of blood vessels of the pampiniform plexus were examined with the use of colour coded Doppler technique, and obtained data was evaluated with the PXFX software. The more objective digital evaluation of data obtained with colour Doppler sonography through the application of dynamic tissue perfusion measurements provides new opportunities for diagnosis, as well as continuous monitoring of the function of the examined tissues and organs. The use of PXFX software is strongly indicated as a tool in small animal practice as an additional method for evaluation of tissue perfusion, especially in the cases when other methods like pulsed wave Doppler techniques are difficult to be performed
Seasonal variability of basic pollution parameters in atmospheric precipitation in Strzelin
Authors: Jawecki Bartosz , Burszta-Adamiak Ewa 
Published: March 2014

Abstract
Electrical conductivity and pH are the basic indices of rainfall pollution, constituting the basis for evaluation of the general nature of rainwater. This article presents an analysis of these two parameters in samples of rainfall collected in the years 2008-2010 (in the heating season and outside it) in three measurement sites P1, P2 and P3, located in the city and commune Strzelin (Lower Silesian Voivodeship). Preliminary results show a high variation of pH and electrical conductivity of rainfall occurring in the analysed area. Approximately 30% of the samples were characterised by a pH that allowed to qualify them, according to JANSEN et al. [1988], as normal rainfall. A similar share in all the collected samples represented rainfall of pH < 5.1 that was classified as slightly, considerably and highly acidic. The problem of acid rain occurred in the analysed area mainly during the heating season, when rainfall of pH < 5.1 accounted for a considerable share in all rainfall samples collected in the said period. The electrical conductivity of most samples fell below 60 μS·cm-1, which allowed us to classify them as slightly polluted rainfall (site P2), considerably polluted (site P3) and highly polluted (site P1).

Authors: Brinkis K. , Kreslins V. , Mutule A. 
Published: March 2014

ABSTRACT
Power system (PS) blackouts still persist worldwide, evidencing that the existing protective structures need to be improved. The discussed requirements and criteria to be met for joint synchronous operation of large and super-large united PSs should be based on close co-ordination of operative and technological management of all PSs involved in order to ensure secure and stable electricity supply and minimise or avoid the threat of a total PS blackout. The authors analyse the July 2012 India blackout - the largest power outage in history, which affected over 620 million people, i.e. half of India’s population and spread across its 22 states. The analysis is of a general character, being applicable also to similar blackouts that have occurred in Europe and worldwide since 2003. The authors summarise and develop the main principles and methods of operative and technological management aimed at preventing total blackouts in large and super-large PSs.

Published: March 2014

Abstract
In CNG station, the fuel is usually stored in the cascade storage bank to utilize the station more efficiently. The cascade storage bank is generally divided into three reservoirs, commonly termed low, medium and high-pressure storage bank. The pressures within these reservoirs have huge effects on the performance of the stations. In the current study, a theoretical simulation based on mass balance and thermodynamic laws has been developed to study the dynamic fast fi lling process of vehicle’s (NGV) cylinder from the cascade storage bank. The dynamic change of the parameters within the storage bank is also considered. Natural gas is assumed to contain only its major component, methane, and so thermodynamic properties table has been employed for finding the thermodynamics properties. Also the system is assumed as a lumped adiabatic system. The results show that the initial pressure of the cascade storage bank has a big effect on the storage bank volumes for bringing up the NGV cylinder to its target pressure (200 bar). The results also showed that ambient temperature has effect on the refueling process, chiefly the final NGV cylinder and the cascade storage bank conditions
Selective recovery of cobalt(II) towards lithium(I) from chloride media by transport across polymer inclusion membrane with triisooctylamine
Authors: Pospiech Beata 
Published: March 2014

Abstract
In this work the selective transport of cobalt(II) and lithium(I) ions from aqueous chloride solutions through polymer inclusion membranes (PIMs) is presented. Triisooctylamine (TIOA) has been applied as the ion carrier in membrane. The effects of various parameters on the transport of Co(II) and Li(I) were studied. The obtained results show that Co(II) ions were effectively removed from source phase through PIM containing 32 wt.% TIOA, 22 wt.% CTA (cellulose triacetate) and 46 wt.% ONPOE (o-nitrophenyl octyl ether) or ONPPE (o-nitrophenyl pentyl ether) into deionized water as the receiving phase. The results indicate that there is a possibility of polymer inclusion membranes application to recover Co(II) and Li(I) from aqueous chloride solutions

Authors: Ulatowska Justyna , Polowczyk Izabela , Sawiński Wojciech , Bastrzyk Anna , Koźlecki Tomasz , Sadowski Zygmunt 
Published: March 2014

Abstract
The objective of the present study is to assess the efficiency of fly ash and fly ash agglomerates to remove arsenic(III) from aqueous solution. The maximum static uptakes were achieved to be 13.5 and 5.7 mgAs(III)/adsorbent for nonagglomerated material and agglomerated one, respectively. Isotherm studies showed good fit with the Langmuir (fly ash) and the Freundlich (fly ash agglomerates) isotherm models. Kinetic studies indicated that the sorption of arsenic on fly ash and its agglomerates follows the pseudo-second-order (PSO) chemisorption model (R2 = 0.999). Thermodynamic parameters revealed an endothermic nature of As(III) adsorption on such adsorbents. The adsorption results confirmed that fly ash and its agglomerates can be used for As(III) removal from aqueous solutions. Fly ash can adsorb more arsenic(III) than agglomerates, which are easier to use, because this material is less dusty and easier to separate from solution.

Published: March 2014

Abstract
The study presents a technology of sodium tripolyphosphate (STPP) production with the use of a dry, single-stage method. The reacting substrates (concentrated wet-process phosphoric acid - WPPA and solid Na2CO3 ) are mixed with a recycled final product (STPP) in a mixer, then a „quasi-dry” mixture is calcined in a rotary kiln. Thanks to that, some stages of a classic method of STPP production are eliminated: one of the two-stage neutralization of the phosphoric acid with sodium carbonate at temperature ~80°C, filtration of the neutralised solution and its evaporation, as well as the stage of drying a solution of mono- and di-sodium orthophosphate in a spray dryer. According to the presented technical and economical analysis, the costs of STPP production using a single-stage dry method can be 10% lower compared to the classic method.

Published: March 2014

Abstract
Anodic aluminum oxide (AAO) has been fabricated in the 0.3 M oxalic acid at voltage range 20-60 V and temperature range of 35-50oC. The resulting nanoporous alumina surfaces were characterized by high resolution scanning electron microscopy, and the images were quantitatively analysed by means of an innovative approach based on fast Fourier transform. The influence of operating anodization voltage and electrolyte temperature on nanopores geometry (pore diameter, interpore distance, porosity, pores density) and arrangement has been studied in details and compared to literature data and theoretical calculations. It was found that independently from the temperature, the best arrangement of the nanopores is for anodic aluminum oxide formed at voltages ranging from 40 to 50 V. Moreover, it was found that pore diameter and interpore distance increase linearly with voltage, what is in line with the literature data.
Chemistry for nanotechnology
Authors: Schroeder Grzegorz , Kurczewska Joanna 
Published: March 2014

Abstract
In recent years, the processing order during the synthesis of new chemical compounds has been redefined. Until now a chemist considered primarily receiving a new compound and only then searched for its potential application. The new philosophy of proceedings forces chemists to answer the question: what physical and chemical properties a new chemical compound must have, and what should be structured. After that it has to be planned how to get the compound including the defined budget. The compounds obtained by conventional chemical synthesis are then used to create new functional materials having the properties as scheduled. The paper presents the way of the proceedings from a molecular receptor to a new nanomaterial containing this receptor, so in other words from individual molecules to new material with specific and previously planned properties.

Authors: Pełech Iwona , Narkiewicz Urszula , Kaczmarek Agnieszka , Jędrzejewska Anna 
Published: March 2014

Abstract
Transition metal catalysts (mainly: iron, cobalt and nickel) on various supports are successfully used in a largescale production of carbon nanotubes (CNTs), but after the synthesis it is necessary to perform very aggressive purification treatments that cause damages of CNTs and are not always effective. In this work a preparation of unsupported catalysts and their application to the multi-walled carbon nanotubes synthesis is presented. Iron, cobalt and bimetallic iron-cobalt catalysts were obtained by co-precipitation of iron and cobalt ions followed by solid state reactions. Although metal particles were not supported on the hard-to-reduce oxides, these catalysts showed nanometric dimensions. The catalysts were used for the growth of multi-walled carbon nanotubes by the chemical vapor deposition method. The syntheses were conducted under ethylene - argon atmosphere at 700°C. The obtained catalysts and carbon materials after the synthesis were characterized using transmission electron microscopy (TEM), X-ray diffraction method (XRD), Raman spectroscopy and thermogravimetric analysis (TG). The effect of the kind of catalyst on the properties of the obtained carbon material has been described.
Type-2 fuzzy logic control of a 2-DOF helicopter (TRMS system)
Authors: Zeghlache Samir , Kara Kamel , Saigaa Djamel 
Published: March 2014

AbstractThe helicopter dynamic includes nonlinearities, parametric uncertainties and is subject to unknown external disturbances. Such complicated dynamics involve designing sophisticated control algorithms that can deal with these difficulties. In this paper, a type 2 fuzzy logic PID controller is proposed for TRMS (twin rotor mimo system) control problem. Using triangular membership functions and based on a human operator experience, two controllers are designed to control the position of the yaw and the pitch angles of the TRMS. Simulation results are given to illustrate the effectiveness of the proposed control scheme.
Reclaiming Third World Feminism
Authors: Herr Ranjoo Seodu 
Published: March 2014

Abstract
Third World and transnational feminisms have emerged in opposition to white second-wave feminists' single-pronged analyses of gender oppression that elided Third World women's multiple and complex oppressions in their various social locations. Consequently, these feminisms share two “Third World feminist” mandates: First, feminist analyses of Third World women's oppression and resistance should be historically situated; and second, Third World women's agency and voices should be respected. Despite these shared mandates, they have diverged in their proper domains of investigation, with transnational feminism concentrating on the transnational level and Third World feminism focusing on local and national contexts. Further, their respective positions regarding nation-states and nationalism have been antithetical, as leading transnational feminists have categorically rejected nation-states and nationalism as detrimental to feminism. In recent decades, transnational feminism has become the dominant feminist position on Third World women, overshadowing Third World feminism, and the dismissal of nation-states and nationalism as irrelevant to feminism has become fashionable. Against this current trend, this article argues for the relevance of nation-states and nationalism for transnational feminism and the urgency of reclaiming Third World feminism.
An Intersectional Analysis of Sex Trafficking Films
Authors: Baker Carrie N. 
Published: March 2014

Abstract
This essay analyzes the portrayal of sex trafficking in representative dramas and documentaries, both Hollywood and independent films. The majority of these films use a rescue narrative to tell the story of sex trafficking: an innocent and naïve young woman or girl is tricked or abducted by a villainous trafficker, who imprisons her and controls her with brutal violence until a heroic rescuer overcomes tremendous adversity in order to save her. Race and nationality inflect this gendered narrative: the rescuers are usually white, Western men and the traffickers are from Eastern Europe and/or are men of color. The issue of sex trafficking is portrayed simplistically, in black and white terms, with a clear bad guy, innocent victim, and savior. Often these films focus on the extreme, and least common, form of trafficking: a minor being abducted off the street and transported violently across national borders to be sold at auction. These films focus on criminal perpetrators and criminal-justice solutions, rather than on the broader systemic causes of sex trafficking, like globalization, economic inequality, poverty, and ethnic, race, and gender oppressions. This essay will discuss the 2007 Hollywood movie Trade, the 2010 Hollywood movie Taken, and the 2007 independent drama Holly as well as the NBC dateline special Children for Sale. The essay will then turn to several films that portray sex trafficking in more complex and nuanced ways: the 2OO3 film Trading Women, the 1999 film Sacrifice, and the 2007 film Very Young Girls. The essay concludes by calling for more films that portray a wider range of experiences not based on myths about trafficking that lead to simple criminal-justice-oriented solutions, but that explore the complexity of sex trafficking and show the need for localized solutions that address the systemic conditions that fuel sex trafficking.
In Her Own Image
Authors: Vásquez Sam 
Published: March 2014

AbstractDespite striking similarities in their work and increased attention to the transnational Americas, there are few detailed comparisons between writers such as Toni Morrison (the most lauded African American female author of the twentieth century), and Jamaica Kincaid (the most critically and commercially successful female Caribbean writer). For example, the common approach to examining Morrison's groundbreaking novel The Bluest Eye (1970) is to foreground its national significance, or, less frequently, to apply its discourses quite generally and loosely to other cultural contexts like Latin America. However, building on relatively recent attempts to locate Morrison in broader transnational spaces, in this discussion, I propose closely examining a text from another Anglophone, African diasporic context, which utilizes many of the strategies evident in Bluest —Kincaid's Annie John (1985). By engaging the larger English-speaking Americas, such an approach highlights the transnational implications of the race and gender paradigms Morrison deploys; also, although Annie John is commonly categorized as primarily Caribbean (a precursor to Kincaid's “American” sequel, Lucy [1990]), my proposed comparison elucidates the Western and transnational leanings of this foundational “Caribbean” work and the ways in which it implicitly expands on Morrison's representations of female autonomy and visual culture. To that end, I borrow from and expand on Cheryl Wall's notion of “worrying the line” (Wall 2005)—black women writers' emphasizing, clarification, and subversion of literary traditions—to examine how black women in different cultural contexts write themselves into visual and historical records. Contributing to burgeoning interest in the Americas as a transnational space, I argue that Kincaid appropriates Morrison's treatment of visual culture, gender, and identity, presenting similar dynamics in another African diasporic community and depicting even more autonomous female characters.
