Olowalu Review: Developing identity through translanguaging in a multilingual literary magazine
Authors: Kasula Alex Josef
Published: October 2016

With the current trends in our globalized society, there is a clear increase in multilinguals rise; however, the understanding of multilingual identity and policy towards education stays relatively the same. Recent investigation in multilingualism in the US has shed light on the positive impacts of alternating policy in language education with regard to a greater understanding in how translanguaging and identity impact the language learner and language learning policies (Garcia & Wei, 2013). The following article describes the development of an online multilingual literary magazine, Olowalu Review, that aimed to provide English language learners in an English-only language policy a space to translanguage. Thus, having the opportunity to develop and express their multilingual identities. Goals and the development of the magazine are described in terms relating to current multilingual theory. While the outcomes and findings reveal how Olowalu Review enabled multilinguals to foster and exercise multilingual identities and skills, raise multilingual awareness, and act as an important multilingual artifact through an analysis of written submissions and interviews with authors. Pedagogical implications are discussed to empower language teachers, learners, or artists to develop the same or similar project for their own local, national, or global community.
Del arte y la memoria

Published: October 2016

Durante buenos años nos hemos preguntado con insistencia de qué manera el aparato educativo y cultural ha permitido, tal vez suscitado, la desmemoria, el abandono del pasado por parte de la sociedad en que vivimos.[1] Esta edición de Calle 14 y la siguiente, abordan el tema de la memoria, la historia y sus relaciones con el arte, y bien podrían llegar a plantear algunas respuestas, con la colaboración de quienes han pensado el asunto a profundidad y tienen méritos para ser tenidos en cuenta.[1] Ramírez, Camilo, “Vigencia del Teatro Histórico”, CIDC Universidad Distrital Francisco José de Caldas, 2014
ANÁLISIS DE LA VEGETACIÓN SUCESIONAL EN UN FRAGMENTO DE BOSQUE SECO TROPICAL EN TOLUVIEJO-SUCRE (COLOMBIA)
Authors: Olascuaga Vargas Dayana , Mercado Gomez Jorge , Sanchez Montaño Luis
Published: October 2016

Se realizó la caracterización estructural y composición florística de la vegetación sucesional en un fragmento de bosque seco tropical en Toluviejo-Sucre (Colombia). Se registraron tres estados de sucesión en los que se determinaron los índices de diversidad y se compararon mediante un análisis de correspondencia sin tendencia. Se registraron 138 especies distribuidas en 111 géneros y 42 familias. La familia Fabaceae presentó mayor riqueza con 21 especies y 18 géneros, seguida de Sapindaceae y Rubiaceae. El hábito mejor representado en términos de riqueza de especies para el matorral (estado temprano) fueron los arbustos (37.6%); en el borde del bosque (estado intermedio) los árboles (58.8%) y en el bosque (estado tardío) árboles (67.5%). El estado intermedio presenta mayor diversidad de especies que el estado tardío. El estrato temprano presentó mayor dominancia debido al alto grado de perturbación antrópica y al proceso de colonización de especies. Según el DCA, las etapas que muestran mayor similitud son el EI (estado intermedio) y el ETA (estado tardío), debido a las semejanzas en el clima, condiciones edáficas y factores bióticos. Este estudio aporta conocimientos relevantes para fomentar proyectos de conservación de áreas, así como para planes de manejo de la vegetación

Authors: Devia Castillo Carlos Alfonso , Reyes Fredy , Morales Ivónn , Morris Michel , Pareja Juan
Published: October 2016

El presente artículo propone sustituir losas en concreto utilizadas para el sistema de transporte masivo Transmilenio por prefabricados de madera, como son las vigas laminadas, como estructura de pavimento con capa de rodadura.

Se evaluó el comportamiento mecánico de la madera de dos especies (Pinus caribaea y Eucalyptus tereticornis) a partir de simulaciones por el método de elementos finitos, posteriormente se determinó la configuración óptima para el diseño en madera y finalmente se verificó en laboratorio la configuración óptima determinada con la simulación para un diseño de 440 000 ejes. Con el uso de la máquina Universal de Ensayos y una carga de 6.50 toneladas equivalente a la de un semieje simple con dos ruedas, se encontró que el espesor de la losa de madera varía entre 0.125 y 0.24 metros para resistir esta carga.

Se encontró que técnicamente los sistemas constructivos prefabricados con madera son una alternativa válida dentro del mercado de la construcción de pavimentos en la parte estructural. Adicionalmente corresponden a una innovación al ser una modificación en el sistema estructural de las losas, además de reducir el impacto ambiental.
The Life-Saving Case of "Cora": A Rogerian Perspective
Authors: Bohart Arthur C.
Published: October 2016

Halvorsen, Benum, Haavind, and McLeod’s (2016) A Life-Saving Therapy: The Theory-Building Case of "Cora" is rich in ideas and findings. My reflections fall into four categories. First, I comment on the finding that therapist and client reports of change in the case of Cora differ from results on objective measures. I argue that an extensive qualitative examination could better resolve this issue. Second, I raise questions concerning the idea that clients’ problems necessarily stem from early childhood abuse. Third, I argue that the authors’ finding of the importance of persistence in therapy may better explain how therapy works than a primary focus on significant events or significant moments. Finally, I agree with the authors’ finding of client courage, but give an alternative interpretation of that.
The Case of "Cora": Clinical and Methodological Perspectives
Authors: Timulak Ladislav , Keogh Daragh
Published: October 2016

In this commentary we explore the clinical aspects of Halvorsen, Benum, Haavind, and McLeod’s (2016) compelling case study of “Cora.” We were humbled by the courage and commitment of both the client and the therapist in the case. We begin by providing our perspective on how the therapist’s flexibility regarding certain boundaries helped to build trust between him and the client; and on how this trust in turn allowed the client find the courage to bring the most painful aspects of her experience to therapy. We then comment on certain methodological aspects of the case study. We discuss ways in which the steps describing the choices authors made could have been made more explicit. We question the necessity to present the case in the format of Interpretative Phenomenological Analysis (IPA; Smith, Flowers, & Larkin, 2009). We also question whether “theory building case study” is the best description for this particular study. In addition, we comment briefly on some of the themes reported by the study and share our own interpretative process, pointing out both the significant overlap and also those points where our interpretation may differ from the authors, including the role of transference interpretations and immediacy in the success of the case. Finally, we provide our perspective on the discrepancy between the quantitative versus qualitative outcomes obtained in the case.
Considering "Cora"
Authors: Altman Alexandra Jessup , Miller Ronald B.
Published: October 2016

This discussion examines Halvorsen, Benum, Haavind, and McLeod’s (2016) case study of “Cora,” from a perspective both appreciative and at times critical of certain mixed-study methods it employs. While impressed with the clinical alliance it illustrates between therapist and challenging client, we find the study raises more theoretical questions than it answers in terms of our ability to enumerate the conceptual elements necessary to convey valuable clinical truths. The case study does indeed provide systematic data on the presence of dyadic courage, persistence, and symbolic expressions of trust during treatment from which there is much to be learned. As readers we were left marveling at an account of a therapist’s clinical acumen with a client who had faced unbearable childhood trauma, and at the same time wondering how much more we might have learned about how to actually do such work from a comprehensive narrative written in his own voice.
Social Tourism as a Social and Economic Category – Some Elements of Development
Authors: Knežević Mladen
Published: October 2016

Social tourism is in some specific forms older than the tourist industry as we know it in the modern period of its development. In its modern form is a child of the modern industrial society. Many elements of the modern tourist development meant progress because of the strongly marked social component, and some areas have begun to develop markedly after a “social tourism” have been developed in them. The modern tourism and modern social tourism in some countries, particularly high-income countries harmoniously complement and contribute to the economies of their countries. On the other hand, as the dominant economic activity, help the social and personal development members of the social classes whose financial status is very sensitive, and sometimes even threatening.

Mining Deployment Optimization
Authors: Čech Jozef
Published: October 2016

The deployment problem, researched primarily in the military sector, is emerging in some other industries, mining included. The principal decision is how to deploy some activities in space and time to achieve desired outcome while complying with certain requirements or limits. Requirements and limits are on the side constraints, while minimizing costs or maximizing some benefits are on the side of objectives. A model with application to mining of polymetallic deposit is presented. To obtain quick and immediate decision solutions for a mining engineer with experimental possibilities is the main intention of a computer-based tool. The task is to determine strategic deployment of mining activities on a deposit, meeting planned output from the mine and at the same time complying with limited reserves and haulage capacities. Priorities and benefits can be formulated by the planner.
Mercury in Bituminous Coal Used in Polish Power Plants
Authors: Burmistrz Piotr , Kogut Krzysztof
Published: October 2016

Poland is a country with the highest anthropogenic mercury emission in the European Union. According to the National Centre for Emissions Management (NCEM) estimation yearly emission exceeds 10 Mg. Within that approximately 56% is a result of energetic coal combustion. In 121 studied coal samples from 30 coal mines an average mercury content was 112.9 ppb with variation between 30 and 321 ppb. These coals have relatively large contents of chlorine and bromine. Such chemical composition is benefitial to formation of oxidized mercury Hg2+, which is easier to remove in Air Pollution Control Devices. The Hgr/Qir (mercury content to net calorific value in working state) ratio varied between 1.187 and 13.758 g Hg · TJ−1, and arithmetic mean was 4.713 g Hg · TJ−1. Obtained results are close to the most recent NCEM mercury emission factor of 1.498 g Hg · TJ−1. Value obtained by us is more reliable that emission factor from 2011 (6.4 g Hg · TJ−1), which caused overestimation of mercury emission from energetic coal combustion.
Results of the Verification of the Statistical Distribution Model of Microseismicity Emission Characteristics
Authors: Cianciara Aleksander
Published: October 2016

The paper presents the results of research aimed at verifying the hypothesis that the Weibull distribution is an appropriate statistical distribution model of microseismicity emission characteristics, namely: energy of phenomena and inter-event time. It is understood that the emission under consideration is induced by the natural rock mass fracturing. Because the recorded emission contain noise, therefore, it is subjected to an appropriate filtering. The study has been conducted using the method of statistical verification of null hypothesis that the Weibull distribution fits the empirical cumulative distribution function. As the model describing the cumulative distribution function is given in an analytical form, its verification may be performed using the Kolmogorov-Smirnov goodness-of-fit test. Interpretations by means of probabilistic methods require specifying the correct model describing the statistical distribution of data. Because in these methods measurement data are not used directly, but their statistical distributions, e.g., in the method based on the hazard analysis, or in that that uses maximum value statistics.

A usefulness of known methods for estimations of maximal amplitudes of suspended vibrating screens, in the transient resonance, was analysed in the paper. The way of adapting – for this type of machines – the new, developed by the authors, methods of analysing the transient resonance was indicated. Their accuracy was estimated by comparing the obtained results with the results of simulation investigations performed on the model, which takes into account the influence of the body vibrations on the vibrator motion.
Roof Weakening of Hydraulic Fracturing for Control of Hanging Roof in the Face End of High Gassy Coal Longwall Mining: A Case Study
Authors: Huang Bingxiang , Wang Youzhuang
Published: October 2016

The occurence of hanging roof commonly arises in the face end of longwall coal mining under hard roof conditions. The sudden break and subsequent caving of a hanging roof could result in the extrusion of gas in the gob to the face, causing gas concentrations to rise sharply and to increase to over a safety-limited value. A series of linear fracturing-holes of 32 mm diameter were drilled into the roof of the entries with an anchor rig. According to the theory that the gob should be fully filled with the fragmentized falling roof rock, the drilling depth is determined as being 3~5 times the mining height if the broken expansion coefficient takes an empirical value. Considering the general extension range of cracks and the supporting form of the entryway, the spacing distance between two drilling holes is determined as being 1~2 times the crack’s range of extension. Using a mounting pipe, a high pressure resistant sealing device of a small diameter-size was sent to the designated location for the high-pressure hydraulic fracturing of the roof rock. The hydraulic fracturing created the main hydro-fracturing crack and airfoil branch cracks in the interior of the roof-rock, transforming the roof structure and weakening the strength of the roof to form a weak plane which accelerated roof caving, and eventually induced the full caving in of the roof in time with the help of ground pressure. For holes deeper than 4 m, retreating hydraulic fracturing could ensure the uniformity of crack extension. Tested and applied at several mines in Shengdong Mining District, the highest ruptured water pressure was found to be 55 MPa, and the hanging roof at the face end was reduced in length from 12 m to less than 1~2 m. This technology has eliminated the risk of the extrusion of gas which has accumulated in the gob.

Ultrasound-assisted osmotic dehydration and convective drying of apples: Process kinetics and quality issues
Authors: Mierzwa Dominik , Kowalski Stefan J.
Published: October 2016

The aim of the present theme issue was to study the influence of ultrasound enhancement on the kinetics of osmotic dehydration and the effect of convective drying from the point of view of drying time and quality of dried products. Apple fruit was used as the experimental material. The kinetics of osmotic dehydration with (UAOD) and without (OD) ultrasound enhancement were examined for 40% fructose and sorbitol solutions. The effective dehydration time of osmotic process was determined. Preliminary dehydrated samples with OD and UAOD were next dried convectively with (CVUS) and without (CV) ultrasound assistance. The influence of OD and UAOD on the kinetics of CV and CVUS drying was analysed. The parameters of water activity and colour change were measured for the assessment of product quality after drying process.
Analysis of the mechanism of gas bubble break-up in liquids during the self-aspirating impeller operation
Authors: Stelmach Jacek , Kuncewicz Czesław , Musoski Radosław
Published: October 2016

Feasibility of a model of gas bubble break-up and coalescence in an air-lift column enabling determination of bubble size distributions in a mixer with a self-aspirating impeller has been attempted in this paper. According to velocity measurements made by the PIV method with a self-aspirating impeller and Smagorinski’s model, the spatial distribution of turbulent energy dissipation rate close to the impeller was determined. This allowed to positively verify the dependence of gas bubble velocity used in the model, in relation to turbulent energy dissipation rate. Furthermore, the range of the eddy sizes capable of breaking up the gas bubbles was determined. The verified model was found to be greatly useful, but because of the simplifying assumptions some discrepancies of experimental and model results were observed.
Cultural Rural Development in the Czech Republic (Case Study of the Liberec Region)
Authors: Antošová Gabriela
Published: October 2016

The contribution aims at determining the endogenous potential for a proposal for sustainability and potential development of tourist destinations located in the Czech border areas - Liberec region - that lag behind in rural development. Based on the results of the empirical research, according to optimal scaling the ASEB-C analysis is applied suggesting the LAC (Limits of Acceptable Change) planning system will improve sustainability and competitiveness of all LAU 1 (in the Liberec region) and of the specific touristic destinations. The potential of development in the Czech border areas is in the stagnation phase, due to the fear and (dis)embedded identity in some less developed border areas. It should be evident that even in the Czech rural border areas the potential of “growth of endogenous potentials seems feasible” in combination with an endogenous and exogenous model of regional rural development.

Authors: Yaneva Blagovesta K. , Zagorchev Plamen I. , Firkova Elena I. , Glavinkov Ivan T.
Published: October 2016

Aim: To assess temperature changes at specified time intervals during Er:YAG laser scaling and root planing of surfaces with dental calculus.

Materials and methods: Fifteen single-rooted teeth with advanced periodontal disease were extracted and fixed in a cylinder thermostat filled with distilled water at constant temperature (35.5°C). A specially designed thermal probe (type K thermocouple) accurate to ±0.1°C over the range from 20°C to 80°C was fitted into the pulp chamber of tooth sample. Scaling and root planing of the mesial and distal root surfaces was performed using an Er:YAG laser (Lite Touch, Syneron Dental, Israel) with a wavelength of 2940 nm, provided with a chisel tip, and at the following settings: output energy 100 mJ and 50 Hz, duration of irradiation - 40 sec, the tip in contact mode oblique to the root surface at an angle of approximately 10-15 degrees and water spray level 5-6. The temperature inside the pulp chamber was measured every 10 sec.

Results: The temperature in the pulp chamber taken every 10 seconds and compared with the temperature of 35.5°C at baseline decreased by 1.6°C, 2.4°C, 2.5°C, and 2.5°C for the first, second, third and fourth measurement, respectively. These changes did not reach statistical significance.

Conclusion: The Er:YAG laser does not increase the temperature inside the pulp chamber. The assessed changes do not depend on the duration of irradiation which was kept within 40 seconds. Therefore, this treatment modality causes no thermal damage to the pulp under the above defined conditions and can be considered safe.

Published: October 2016

Aim: To assess the effect of the factor ‘hepatic metastatic disease’ on long-term outcomes in patients with colorectal cancer.

Materials and methods: We analysed retrospectively 200 randomly selected patients. Forty-two of them were excluded from the study for different reasons so the study contingent was 158 patients over a period of 23 years. All were diagnosed and treated in the Lozenetz University Hospital, in the Department of General Surgery. 125 of the patients were diagnosed with colorectal cancer without distant metastases and 33 of the patients had liver metastases as a result of colorectal carcinoma. The statistical analysis was performed using SPSS 19 IMB, with a level of significance of P < 0.05 at which the null hypothesis is rejected. We also used descriptive analysis, Kaplan-Meier estimator, Log-Rank Test and Life-Table statistics models.

Results: The median survival for patients without metastases was 160 months, and the median was 102 months. The median survival for patients with liver metastases was 28 months and the median was 21 months. One-year survival for patients without metastases was 92% versus 69% in patients with liver metastases. Conclusion: Average, annual and median survivals are influenced statistically significantly by the presence of liver metastases compared to overall survival and that of patients without metastatic colorectal cancer. Liver metastatic disease is a proven factor affecting long-term prognosis and survival in patients with colorectal cancer.

Authors: Nenova Ivanka S. , Valcheva Mariana Y. , Beleva Elina A. , Tumbeva Dora Y. , Yaneva Marianna P. , Rancheva Emilia L. , Grudeva-Popova Zhanet G.
Published: October 2016

Introduction: Autoimmune disorders have been documented in solid tumors and malignant hematological disorders. They are very common and well studied in lymphomas which are associated with immune imbalance. They are less common in solid tumors and are categorized as paraneoplastic syndromes with unclear pathogenesis.

Aim: The aim of the present study was to find the frequency of autoimmune phenomena in solid tumors of various origin, location and status of the tumor.

Patients and methods: Between 2000 and 2014 we studied 1083 patients with solid tumors that were diagnosed and treated in St George University Hospital, Plovdiv.

Results: We found higher incidence of these phenomena in prostate and ovarian carcinomas (9.01% and 5.6%, respectively) than in other solid tumors. Their distribution by type of autoimmune disease showed that vasculitis, polyneuritis and autoimmune hemolytic anemia have the highest frequency of all. Immune thrombocytopenia, seronegative arthritis, psoriasis, polymyositis are less commonly documented. The autoimmune paraneoplastic phenomena manifest themselves metachronously, less commonly synchronously, with the tumor. In most cases, their clinical manifestation is a progressive disease or metastatic malignant disorder which respond favourably to therapy.

Conclusion: Paraneoplastic autoimmune phenomena are found very commonly in prostate and ovarian carcinomas. They occur in the course of the evolvement of neoplasm and can regress with medicamentous or surgical treatment of the malignoma.

Published: October 2016

Aim: To assess relationships between functional changes in visual field and structural changes in advanced open-angle glaucoma (OAG) found using spectral-domain optical coherence tomography (SD-OCT).

Methods: Thirty-one eyes of 25 patients with OAG were included in this study. Besides the routine ophthalmological exam the patients underwent standard automated perimetry (SAP) (Humphrey Field Analyzer) and SD-OCT (RTVue–100) performed within 6 months. The global perimetric indices in the study group were as follows: mean deviation (MD) 12.33±6.18 dB and pattern standard deviation (PSD) 9.17±3.41 dB. The relationship between OCT measurements and MD and PSD was evaluated by correlation analysis (Pearson’s correlation coefficient) and regression analysis (linear and nonlinear regression models).

Results: Thickness measurements of the lower halves of ganglion cell complex (GCC) and retinal nerve fiber layer by two scanning protocols (ONH and 3.45) showed these to be thinner than the upper halves, but the difference failed to reach statistical significance. The correlations between global indices MD/PSD and most of the analysed quantitative OCT measurements were moderate (r in the range between 0.3 and 0.6). The correlation between MD and GCC showed nonlinear cubic regression (R2=0.417, P=0.004). Good correlation was found between MD and GLV (R2=0.383; P=0.008). Linear regression (P<0.05) was found only between MD and Cup area (R2=0.175, P=0.024) and between MD and RNFL by 3.45 protocol (R2=0.131, P=0.045).

Conclusion: Nonlinear regressive models appear to be more appropriate in the assessment of the correlations between functional and structural changes in eyes with advanced glaucoma. The correlations we found were moderate.
Total Antibiotics — A New Possible Alternative for the Screening of Coccidiostat Residues in Poultry Meat
Authors: Jeevanandan V. , Kožárová I.
Published: October 2016

The Total Antibiotics test is a microbial inhibition test which has been recently introduced for the detection of antibiotics in meat. The aim of this study was to determine whether it would be suitable for the detection of coccidiostats in poultry meat. A comparison with the Premi®Test was assessed also for the suitability of the detection of coccidiostats in poultry meat. A selection of poultry meat samples of different organ parts were assessed with 14 samples from Slovakian farms that had previously been tested for coccidiostats by the Veterinary and Food Institute in Košice. In addition, another 8 samples from varied Slovakian supermarkets such as Lidl, Billa and Tesco with samples of chicken or duck meat, were tested. Each prepared sample was added to the Total Antibiotics kit tubes and incubated. The samples from all sources showed a mixture of positive and negative results for the detection of coccidiostats.

For the Premi®Test, the samples used the same extraction procedure as the Total Antibiotics, placed in Premi®Test kit tubes and incubated. The Premi®Test demonstrated a mixture of positive and negative results, as similar to the Total Antibiotics for coccidiostats in the poultry farm samples. However, the Premi Test revealed many more negative results for the supermarket sources compared to the Total Antibiotics. Therefore, based on the total number of positive results, we concluded that Total Antibiotics is more sensitive for the detection of coccidiostats in poultry meat, but depending on the source of the samples, both Total Antibiotics and Premi®Test had either similar or opposite results for the detection of coccidiostats.

Three Technocratic Cabinets in the Czech Republic: A Symptom of Party Failure?
Authors: Brunclík Miloš
Published: October 2016

This article compares three technocratic cabinets that were appointed in the Czech Republic. Its aim is to determine to what extent the cabinets can be understood as a failure of political parties. The article outlines the concept of party failure. It argues that patterns of party failure can be found in all cases. However, in the last case—the technocratic cabinet of Jiří Rusnok—party failure was only partial and indirect; its technocratic cabinet cannot be interpreted as resulting from an inability of the parties to form a partisan cabinet, but rather it resulted from the president’s imposition of a technocratic cabinet. This imposition took place against the will of the parliamentary parties that sought to form a cabinet composed of party politicians immediately or following early elections.
Three-step Anti-aMPV IgA Expression Profile Evaluation in Turkeys of Different Immunological Status after TRT Vaccination
Authors: Śmiałek M. , Tykałowski B. , Pestka D. , Welenc J. , Stenzel T. , Koncicki A.
Published: October 2016

Maternally derived antibodies (MDA) don not protect turkeys against rhinotracheitis (TRT) but high MDA influences upper respiratory tract (URT) immunity stimulation after avian Metapneumovirus (aMPV) vaccination. Humoral immunity can not be considered as an indicator of protection against TRT, but specific antibodies inhibit aMPV replication and alleviate the course of TRT. Scarce reports indicate the role of IgA in protection against TRT. The aim of our study was to investigate the impact of MDA on stimulation, antigen specificity acquisition of B lymphocytes, and the production of specific IgA after TRT vaccination of turkeys.

The results of our study indicate that MDA on the day of TRT vaccination causes disturbances at different levels of specific humoral immunity expression including antigen specificity acquisition of B IgA+ lymphocytes as well as production and secretion of IgA. Vaccine immunity against aMPV associated with sIgA is well expressed in birds not possessing MDA on the day of TRT vaccination, whereas it is inhibited in MDA+ birds.

These results corroborate our previous findings and indicate that MDA could be responsible for TRT vaccination failure. These findings could explain the observed frequency of TRT field outbreaks despite aMPV vaccination of turkey flocks.

Authors: Dębski B. , Nowicki T. , Zalewski W. , Ochota M. , Mrowiec J. , Twardoń J.
Published: October 2016

The estimation of acute phase proteins (APP), which are recognized as inflammation markers is a good method for animal health monitoring. Several factors such as obesity, age and sex are also known to modulate APP status. We evaluated the influence of pregnancy and lactation in 65 clinically healthy dairy Holstein-Friesian dairy cows, 2nd÷4th lactation, chosen from 3 different dairy farms located in South West part of Poland. Bovine C-reactive protein (CRP), haptoglobin and fibrinogen were assayed using commercial ELISA kits. The highest values of CRP and haptoglobin were observed in cows during the first month after calving. The highest concentrations of fibrinogen was found in a group of cows prior to expected date of parturition and the level of this protein in blood plasma was decreasing during lactation. The significant differences of analyzed APPs among cows before delivery, during first month after calving and in lactation (1-3 months after delivery) suggested that factors like pregnancy and stage of lactation would have an influence on their concentration.
Development and Validation of an Analytical Method for Determination of Ergot Alkaloids in Animal Feedingstuffs with High Performance Liquid Chromatography-fluorescence Detection
Authors: Kowalczyk E. , Patyra E. , Grelik A. , Kwiatek K.
Published: October 2016

A high performance liquid chromatography combined with fluorescence detection (HPLC-FLD) method was developed for determination of five ergot alkaloids (EA): ergometrine, ergotamine, ergocornine, ergocrypine and ergocristine in animal feedingstuffs. The method was based on the application of QuEChERS salts for extraction and modified QuEChERS dispersive SPE for the cleanup step. Alkaloids separation was performed on a C18, 250 mm x 4.6 mm, 5 μm column with the mobile phase containing ammonium carbonate and acetonitrile. The excitation and emission wavelengths were 330 and 420 nm respectively. The method was validated according to the Commission Decision 2002/657/EC and all parameters are in agreement with the requirements of the Decision. Linearity was determined for the concentration range of 25-400 μg/kg. The coefficient of determination (R2) for all curves was from 0.985 to 0.996. The limit of detection (LOD) was in the range 3.23 to 6.53 μg/kg and the limit of quantification (LOQ) from 11.78 to 13.06 μg/kg. The decision limit (CCα) ranged from 29.56 to 43.08 μg/kg and detection capability (CCβ) from 40.65 to 51.01 μg/kg. The highest coefficient of variation (CV) for repeatability was 14.3% and for reproducibility 15.4%.
Use of Elements of the Stewart Model (Strong Ion Approach) – SID3, SID4, Atot/A−, SIDe and SIG for the Diagnostics of Respiratory Acidosis in Brachycephalic Dogs
Authors: Sławuta P. , Sapikowski G. , Sobieraj B.
Published: October 2016

Buffer systems of blood and tissues, which have the ability to bind with and give up hydrogen ions, participate in maintaining the acid-base balance (ABB) of the organism. According to the classic model, the system of carbonic acid and bicarbonates, where the first component serves the role of an acid and the second a base, determines plasma pH. The so-called Stewart model, which assumes that ions in blood serum can be separated into completely dissociated – nonbuffer and not dissociated – buffer ions which may give up or accept H+ions, also describes the ABB of the organism. The goal of the study was to find out whether, during respiratory acidosis, the values of SID3, SID4, Atot/A−, SIDeand SIG change. The study was carried out on 60 adult dogs of the boxer breed (32 males and 28 females) in which, on the basis of an arterial blood test, respiratory acidosis was found. A strong overgrowth of the soft palate tissue requiring a surgical correction was the cause of the ABB disorder. Prior to surgery and on the 14th day after the surgery, venous and arterial blood was drawn from each dog. ABB parameters were determined in the arterial blood sample: the blood pH, pCO2and HCO3−. In the venous blood, concentration of Na+, K+, Cl−, lactate−, albumins, and Pinorganic was determined. On the basis of the obtained data, the values of SID3, SID4, SIDe, A−and SIG, before and after the surgery, were calculated. In spite of the fact that the average concentration of ions, albumins, Pinorganic and lactate in the blood serum of dogs before and after the surgical procedure was similar and within the physiological norms, the values of SID3, SIDeand SIG, calculated on the basis of the former, displayed statistically significant differences. Conclusion: On the basis of the results obtained, it can be stated that the values of SID3, SIDeand SIG change during respiratory acidosis and may be helpful in the diagnostics of ABB disorders in brachycephalic dogs.
Association between SOX5 Genotypes and Semen Quality in Polish Holstein-Friesian Bulls

The aim of this study was to evaluate the effect of C/T missense mutation (SOX5) gene on selected parameters of non-frozen semen in Polish Holstein – Friesian bulls. Three hundred and sixty eight bulls were genotyped by the PCR-Rsa I technique. Semen was collected and evaluated by standardized procedure used in an AI station. Significant associations were found between SOX5 genotypes and sperm concentrations (p=0.020) and sperm motility (p=0.014). Bulls with TT genotype had the lowest values of both traits. Our results demonstrate that C/T missense mutation within the SOX5 gene is involved in bull sperm quality.

Introduction. Alexithymia is related to poor emotion regulation strategies as well as higher rates of somatic disorders. The aim of the present study was to assess the relationship between alexithymia and the general symptoms experienced by the pregnant women.

Material and Methods. In a cross-sectional study, a total number of 350 pregnant women, attending the antenatal clinics, were randomly selected. A standardized Toronto Alexithymia Scale (TAS-20) was used to elicit responses from participants with alexithymia. The general symptoms scores were measured using the Iranian version of the Symptom Checklist-90-Revised, 90 items. The statistical associations between alexithymia and the general symptoms were then investigated through liner regression.

Results. A total number of 186 of pregnant women with alexithymia were compared with the 164 cases without alexithymia. The high scores on Total Toronto Alexithymia Scale-20 and the difficulties to identify feelings emerged as major predictors for the current psychopathology on all SCL-90-R subscales. The difficulty in describing feelings features of alexithymia is positively associated with interpersonal sensitivity and paranoid ideation, but it is inversely associated with the phobic anxiety dimension.

Conclusion. This study showed that the pregnant women with difficulty in describing feelings features of alexithymia are likely to show a broad range of psychopathology. Therefore, it is necessary to emphasize the benefits of specific psychotherapeutic techniques to improve self-differentiation so that we can reduce the likelihood of mental illnesses in pregnant women.
Convective Fins Problem with Variable Thermal Conductivity: An Approach Based on Embedding Green’s Functions into Fixed Point Iterative Schemes
Authors: Kafri H.Q. , Khuri S.A. , Sayfy Ali
Published: October 2016

This article introduces a new numerical approach to solve the equation that models a rectangular purely convecting fin with temperature-dependent thermal conductivity. The algorithm embeds an integral operator, defined in terms of Green’s function, into Krasnoselskii–Mann’s fixed point iteration scheme. The validity of the method is demonstrated by a number of examples that consist of a range of values of the parameters that appear in the model. In addition, the evaluation of the fin efficiency is presented. The residual error computations show that the current method provides highly accurate approximations.
White Plague, Mexican Menace
Authors: Sinclair Heather M.
Published: October 2016

This article examines a debate that emerged in El Paso, Texas at the turn of the twentieth century surrounding the transmission of pulmonary tuberculosis from predominantly Anglo American migrants to the city’s ethnic Mexican population. Reports of Anglo-to-Mexican infections came from cities and towns throughout the U.S. Southwest, but by 1915 El Paso had emerged as the epicenter of the debate. Using popular and professional sources, the article tracks a shift in dominant perceptions of tubercular contagion from an association with white bodies to Mexican ones. An early narrative casts the Mexican female domestic servant as a victim of the infectious indigent white consumptive male health seeker. In 1915, as the Mexican Revolution raged and tensions between whites and ethnic Mexicans in the city sharpened, federal public health authorities published a report dismissing health seekers as a source of contagion to ethnic Mexicans. This article highlights the power of notions of race, gender, and class in shaping perceptions of and responses to epidemics, often with tragic results.

In this study, the properties of bacterial fermentation based poly(hydroxybutyrate-co-hydroxyvalerate) –PHBV thermoplastic biopolymer was investigated by reinforcing natural halloysite nanotubes (HNTs). At first, HNTs were added to PHBV polymer by melt processing technique. The modified PHBV resin was then used to fabricate films using compression molding process. X-ray diffraction (XRD), differential scanning calorimetry (DSC), thermogravimetric analysis (TGA) and tensile tests were performed. XRD results showed mixed intercalated and exfoliated behavior of HNTs in PHBV matrix with an increase in interplanar spacing and decrease in peak intensity. DSC analysis showed that the crystallinity of PHBV resin increased with the increase in HNTs concentration. Also, the DSC endotherm curve showed dual melting peaks indicating formation of different crystalline phases. Higher melting and recrystallization temperature was found in nanophased samples in comparison to the pure PHBV counterpart. The thermal stability, activation energy, tensile and viscoelastic properties of nanophased samples were also increased with an optimum at 3 wt. % HNTs loading. Scanning electron micrographs (SEM) revealed river like pattern in neat films indicating a brittle failure in contrast to rougher surfaces observed in nanophased samples.
Problematizing vocabulary in the second language classroom
Authors: Waring Hansun Zhang , DiFelice Box Catherine , Creider Sarah
Published: October 2016

Research on vocabulary-learning and teaching has predominantly relied on experimental designs and interviews, in which learning is largely treated as an individual rather than a social process, and factors such as repeated exposure and strategy teaching are highlighted, with a focus on planned vocabulary instruction. Relatively less information exists with regard to how vocabulary, let alone unplanned vocabulary, is taught and learned during naturally occurring classroom interaction. Using data from 28 hours of videotaped interaction from 14 different adult English as a Second Language (ESL) classrooms, this conversation analytic study explores how unplanned issues of vocabulary get problematized in situ either unilaterally or bilaterally. While the unilateral approach involves the teacher problematizing an item without any observable evidence of trouble in prior interaction, such evidence is integral to the bilateral approach. Findings of this study may constitute a useful resource for strengthening the professional practice of systematically handling unplanned vocabulary instruction in the language classroom.
Rhetorical and pragmalinguistic features of business correspondence
Authors: Aimoldina Aliya , Zharkynbekova Sholpan
Published: October 2016

This paper explores the rhetorical and pragmalinguistic features of sales letters written in English by Kazakhstani business professionals and their native Englishspeaking international business partners based in the USA and the UK. The analysis focuses on 115 authentic texts, consisting of 65 non-native English speakers’ and 50 native speakers’ letters collected from international, national, and foreign companies in Kazakhstan. The research findings indicate that the analyzed sales letters not only reflect language variations, but also contain a number of culturally specific features which make them valuable ‘indicators’ of the writers’ cultural and social backgrounds. The most remarkable aspect is the imbalance between the Kazakhstani business professionals’ intention to maintain long-term business partnerships by adding a special introductory move and their inability to choose communication strategies adequate to native English-speakers’ writing style.

Published: October 2016

RESUMO: Este artigo parte de uma pesquisa de doutorado que desenvolve a tese de que a formação anterior do(a) professor(a) em Psicologia deixa marcas que influenciam sua ação no ensino de Psicologia da Educação nos cursos de Licenciatura, praticando o que denominamos didática clínica. Neste texto, o objetivo é colocar em discussão essa prática para o ensino de Psicologia da Educação, discutindo temas que contribuem para a reflexão sobre a necessidade de ministrar clinicamente, mesmo que ainda didaticamente, os conteúdos da referida disciplina. Abordaremos, portanto, o uso da didática clínica para o ensino de Psicologia, a formação docente e a dimensão socioafetiva nessa formação, pois a conclusão que delineamos é que, nessa disciplina, não basta trabalhar somente na perspectiva técnica, mas também na formação pessoal do sujeito-aluno, futuro professor, para a prática na sala de aula, no mundo atual.
