Influence of neurotransmitters on lipid peroxidation during immobilization stress exposure in rats of different ages
Authors: Meschaninov V N , Scherbakov D L
Published: October 2015

Aim. To identify age-specific changes of «peroxidation and antioxidant activity» system in rats during immobilization stress exposure and after correction with neurotransmitters.

Methods. The study was conducted on 410 male Wistar rats of mature and old age. Rats was immobilized in plastic canisters for 12 hours. Neurotransmitters - acetylcholine chloride, epinephrine (adrenaline hydrochloride), L-tryptophan, nicotinic acid solutions - were injected subcutaneously. After decapitation lipid peroxidation, antioxidant activity, routine biochemical and hematological parameters were studied in sacrified rats using standardized methods.

Results. Immobilization stress induced phase changes of lipid peroxidation and antioxidant activity in the blood of rats, which corresponds to the stages of stress reaction. Increasing age leads to earlier activation of lipid peroxidation which was observed in old rats. Weakening of the parasympathetic nervous system influence and enhantion of the sympathetic nervous system action was observed with age in the blood of rats, which can lead to age-related changes in the intensity of lipid peroxidation when exposed to stress. In mature and old rats exposed to stress L-tryptophan and nicotinic acid induced antioxidant, in old rats - hypolipidemic geroprophylactic effect.

Conclusion. Immobilization stress exposure causes adverse hyperlipidemic changes in peripheral blood of old age rats. However under the impact of L-tryptophan and nicotinic acid combination normalization of lipid and lipoprotein content of blood occurs showing geroprophylactic hypolipidemic qualities of non-antioxidant genesis.

Authors: Reuk S E , Terekhina N A
Published: October 2015

Aim. To conduct a comparative analysis of acute phase proteins levels and permeability proteins in the tissues of oral mucosa and blood plasma in case of experimental herpetic stomatitis.
Methods. Levels of total protein, C-reactive protein, orosomucoid, α1-antitrypsin, prealbumin, albumin and microalbumin were determined in the homogenates of oral mucosa and blood plasma of 30 rats with experimental herpetic stomatitis.
Results. Levels of C-reactive protein, orosomucoid and α1-antitrypsin in serum of rats with experimental herpetic stomatitis are increased. In the homogenates of the rat oral mucosa, levels of the studied proteins increased significantly, by 1.5-3.5 times compared to the control levels. Total protein, orosomucoid, prealbumin, and microalbumin levels increased not only in tissues affected by herpes, but also in the oral mucosa on the opposite side, indicating alterations of histochematic barrier transport of, most importantly, low molecular weight proteins, increased cell membrane permeability and changes in oral mucosa periodontal tissue structural integrity.
Conclusion. Herpetic infection of the oral cavity is accompanied by increased levels of acute phase reactants in rat oral mucosa both on the side of oral mucosa infected by herpes and on healthy side. The level of not only acute phase proteins, but also low-molecular transport proteins allows to evaluation the alterations of oral mucosa membrane permeability in herpetic stomatitis.

Published: October 2015

В статье анализируется литературный памятник конца XVII «Записки путешествия» Б.П. Шереметева эпохи культурного перелома, который пережила Россия в начале правление Петра I: переход от старых форм жизни к новым европейским. Пристально исследуется взгляд автора «Записок» на Польшу, как на страну, близкого по славянской крови народа, но чуждую конфессионально, уже бывшей тогда, в высшем сословии, страной европейской светской культуры, и являвшейся для России посредником западных веяний. В русском сознании уже тогда сложилась духовно-нравственная оппозиция свой/чужой в отношении к образу этой страны и ее народа: это подтверждается и анализом данного литературного источника.

Analysis of Edward Bond’s War Plays
Authors: Daneshzadeh Amir
Published: October 2015

The War Plays‘trilogy (Red, Black and Ignorant, The Tin Can People and Great Peace) presents the scenario of a waste land ‘with apocalyptical shades. The post nuclear environment of the plays reflects the Atmosphere of the historical period when it was written. The beginning of the eighties saw the debate about nuclear weapons and strong discussions about the Thatcher administration in this respect. Edward Bond emerged from a group of left-wing writers who joined the experimental fringe theatre in the 1970s. To make sense of this literature, we turn to content analysis to examine the trends and categorize the burgeoning management research of the past 25 years that uses content analysis. In Red Black and Ignorant characters confront the paradox. Society uses dramatists to create the drama it needs but a dramatist is not a conduit. He is responsible for what he writes, not out of duty but because discerning anything means evaluating it and this requires desire and commitment. What an author writes expresses the political position that informs his subjectivity. The way he writes shows his relation to himself, which is also his part in the social process. The relation 'creates' what he writes, the limitations come from the limitations of his skill.

Published: October 2015

O acelerado processo de urbanização é um dos fatores determinantes do novo padrão da constituição da atual sociedade brasileira, ligado a um conjunto de transformações sociais, econômicas, políticas e demográficas enfrentado após da década de 1950. Diante do exposto, o presente trabalho tem por finalidade analisar os impactos ambientais ocasionado pela ocupação desordenada, gerando uma maior produção de efluentes domésticos na cidade de Baixio-CE. Durante a pesquisa foi possível observar que os impactos são advindos da questão habitacional. Fenômeno este, agravado pelo fato da Constituição não obrigar que haja Plano Diretor para municípios com população inferior a vinte mil habitantes. Sendo que, é de responsabilidade do município legislar sobre questões relativas a problemas locais. Foi constatado grande quantidade de efluentes domésticos sendo lançado a céu aberto, sem seu devido tratamento, ocasionando sérios danos ambientais, contaminando da água e do solo, podendo ser uma importante forma de transmissão de doenças para a população exposta.

Published: October 2015

Field experiments were carried out during rabi seasons of 2007-08, 2008-09 and 2009-10 to study the influence of tillage operations on crop establishment and productivity of maize in rice fallows of Vizianagaram district. Maximum number of plants per m2 , number of cobs per plant, number of grains per cob and grain weight per cob were recorded in ridge sowing followed by zero tillage sowing. Higher maize yield was recorded in maize under ridge sowing (76.49 q/ha) and zero tillage sowing (75.35 q/ha). The cost of maize cultivation was high in ridge sowing (Rs.26,333 / ha) and low in zero tillage sowing ( Rs.23,000/ha). The comparative economics of maize sowing methods indicated the net income of Rs.58,337/- per ha and B:C ratio of 2.5 with zero tillage sowing; net income of Rs.49,325/- per ha and B:C ratio of 1.78 with ridge sowing; net income of Rs.48,752/- per ha and B:C ratio of 1.89 with conventional line sowing and net income of Rs.45,840/- per ha and B:C ratio of 1.83 with broadcast sowing clearly showing that zero tillage is economically profitable method of maize cultivation.

Authors: Tsukano Y. , Nishi S. , Nishida S. , Ueno M.
Published: October 2015

Most drill collar fatigue failure occurs in the last-engaged thread (LET) of the pin. This type of failure is because of the concentration of thread loading in this area. As a method to decrease the load concentration, the LET thread height reduction is presented in this paper. Firstly, the effectiveness of the LET height reduction was verified using finite element analysis. Secondly, the analytical results were supported using full-size fatigue tests. Finally, the practicability of the redesigned connection was confirmed through torsional test, make-and- break test and full-size tensile test.
Capillary Pressure in Fractured Porous Media
Authors: Firoozabadi A. , Hauge J.
Published: October 2015

A phenomenological model for fracture capillary pressure has been proposed. In this model, the fracture faces are assumed to be covered with cones, where every cone contacts the tip of another opposing cone. Cones in contact at the tip represent both roughness and aperture of a fracture surface. The solution to the Laplace-Young equation of capillarity is used to relate the fracture capillary pressure to the saturation. The computed Pc-saturation results show a porous-media behavior for the fracture capillary pressure.

Experiments with a stack of small matrix blocks in a centrifuge were also conducted. The measured production rates, and the matrix block saturations at the termination of the experiments confirm the validity of the porous-media model for the fracture capillary pressure. In some of the experiments, capillary pressure as high as 40 psi [0.275 MPa] could be imposed on the fractures of the stack of blocks that were used in the centrifuge experiments.

An Experimental Study of Casing Performance Under Thermal Recovery Conditions
Authors: Maruyama K. , Tsuru E. , Ogasawara M. , Inoue Y. , Peters E. J.
Published: October 2015

A study was conducted to investigate the behavior of casing pipe body and connection under simulated thermal recovery conditions. Performed in a new computer-controlled thermal well simulator, the study examined the thermal stress behavior and the leak resistance of the pipe and connection at temperatures up to 354°C (670°F) under severe loading conditions similar to those encountered in thermal wells. Also studied was the biaxial collapse resistance of the casing under the large axial tension that would exist after the cooling period in a steam stimulation process.

Results indicate that in a steam injection process in which the casing is maintained at its maximum temperature for a period of time, stress relaxation can occur in a constrained production casing, resulting in the development of excessive tensile stress during the cooling of the casing. Premium connections with metal-to-metal seal maintained gas leak resistance at temperatures up to 354°C (670°F) whereas the connections without the metal seal did not. The biaxial collapse resistance of casing under large axial tension was dependent on the stress-strain characteristics of the material. Hot-rolled K55 casing with work hardening characteristics showed a higher biaxial collapse resistance than expected from the von Mises yield criterion.

Based on the results of this study, it is concluded that heavy weight K55 casing with premium connection is a good candidate for thermal well completions.
A Laboratory Investigation of Foam Flow in Sandstone at Elevated Pressure

Published: October 2015

Use of foam as a mobility-control fluid in underground applications such as enhanced oil recovery and natural gas or air storage in aquifers requires quantitative information on its flow behavior in porous media at relevant conditions. Little information is currently available in consolidated sands and at pressures characteristic of reservoir depths. We study the flow of foam through a 1.3 μm2 Boise sandstone core at ambient temperature and at back pressures up to 5.2 MPa (750 psia). Total superficial velocities range from 1 to 45 m/day, and inlet foam qualities range from 0.70 to 0.996. Sequential pressure taps and gamma-ray attenuation are used to measure local flow resistances and liquid saturations during transient displacement and in the steady state.

We find that foam in the unsteady state is rheopectic; in the steady state it is shear thinning with respect to increasing gas flow but Newtonian with respect to increasing liquid flow. That is, steady pressure gradients for foam are sensibly independent of gas velocity but increase nearly linearly with increasing liquid velocity. No hysteresis in foam flow resistance is noted. Also at steady state, the pressure profile is linear and the liquid saturation is uniform and constant between 30 and 35%, a value that is about 10 saturation units above connate. The steady-state liquid saturation is practically independent of flow rate and inlet foam quality. Hence, foam flow resistance is not a unique function of liquid saturation.

Steady-state flow behavior of foam is rationalized in terms of changes in bubble texture. We also suggest a unique way of plotting foam flow behavior such that all our data collapse to a single constant which is characteristic only of the porous medium and the stabilizing surfactant package. If proven general, this correlation should be very useful for estimating foam mobilities as input to numerical simulations of possible field applications.

Published: October 2015

A novel method combining a traditional immersion precipitation process for
making membranes with photopolymerization and crosslinking of functional
monomers included in the casting solution was used to prepare asymmetric
polyethersulfone membranes with submicron particles incorporating glycidyl
methacrylate copolymer. In order to introduce sulfonic groups epoxide rings
of glycidyl methacrylate were opened using two methods. The first method was
functionalization with sodium sulfite, and the second method was
functionalization with sulfuric acid and then grafting with
2-acrylamido-2-methylpropane sulfonic acid. Obtained membranes were
characterized using infrared spectroscopy, conductometric titration and water
permeability measurements. Scanning electron microscopy and atomic force
microscopy were used to investigate the surface morphology and topology of
membrane. Dynamic adsorption of Rhodamine B as a model dye was used to
demonstrate suitability of these novel membranes for membrane adsorption
since the adsorption capacity for dye cations was much better for both
functionalized membrane with sodium sulfite and grafted membrane with
2-acrylamido-2-methylpropane sulfonic acid compared to the nonfunctionalized
membrane.
Mapping bound plasmon propagation on a nanoscale stripe waveguide using quantum dots: influence of spacer layer thickness
Authors: Perera Chamanei S , Funston Alison M , Cheng Han-Hao , Vernon Kristy C
Published: October 2015

In this paper we image the highly confined long range plasmons of a nanoscale metal stripe waveguide using quantum emitters. Plasmons were excited using a highly focused 633 nm laser beam and a specially designed grating structure to provide stronger incoupling to the desired mode. A homogeneous thin layer of quantum dots was used to image the near field intensity of the propagating plasmons on the waveguide. We observed that the photoluminescence is quenched when the QD to metal surface distance is less than 10 nm. The optimised spacer layer thickness for the stripe waveguides was found to be around 20 nm. Authors believe that the findings of this paper prove beneficial for the development of plasmonic devices utilising stripe waveguides.
TOURISM AT THE MUSEUM AND THE LIFE-WORLD / MUZIEJŲ TURIZMAS IR GYVENAMASIS PASAULIS

Published: October 2015

Museums are designed to foster tourism and thus minimize controversies. Political maneuvers are a part of this process. The type of politics that is ex- ercised, however, is often quite subtle; control is imposed through minimally invasive practices. Museums, after all, are expected to be neutral sites of dis- cussion and information dissemination. But in the end, museums remove know- ledge from the life-world and create a sterile image of culture. To reverse this trend, and enable museums to be culturally relevant, the creative influence of the life-world must be restored. Santrauka Muziejų paskirtis yra skatinti turizmą ir taip mažinti kontroversijas. Politinių manevrų arena yra šio proceso dalis.

Galų gale tikima, kad muziejai yra tokia vieta, kurioje vystoma neutra- li diskusija ir informacijos sklaida. Tačiau galiausiai muziejai pašalina žinias iš gyvenamojo pasaulio ir sukuria sterilios kultūros įvaizdį.

BUILDING FOR MOVEMENT / SUBRĘSTI JUDESIUI
Authors: Lingis Alphonso
Published: October 2015

The essay grants Martin Heidegger's understanding of human existence as building a dwelling that embodies and discloses the surrounding world – equally required as an extension of building. Moving through the various layers of human dwellings, from huts through mansions, to high rises and gated communities, we think that humans are the privileged species capable of sedentary life in their dwellings. Yet our feet tell us another story, call our being to move across vast panorama of creatures, plants, to discover in nature the wonders that are untouched by human building, to discover the architects and builders of vast and complicated structures in which insects – thousands of species – prove our self-importance wrong. The new environmental movements are already showing us how to live with and in nature, how to let our feet wander – as they are designed to do – without an auto. It is our need to get away from the closed “dwellings” into the open skies, teeming jungles and deep oceans.

This paper provides an exposition about application of neural networks in the context of research to find out the contribution of individual job satisfiers towards work commitment. The purpose of the current study is to build a predictive model to estimate the normalized importance of individual job satisfiers towards work commitment of employees working in TVS Group, an Indian automobile company. The study is based on the tool developed by Spector (1985) and Sue Hayday (2003).The input variable of the study consists of nine independent individual job satisfiers which includes Pay, Promotion, Supervision, Benefits, Rewards, Operating procedures, Co-workers, Work-itself and Communication of Spector (1985) and dependent variable as work commitment of Sue Hayday (2003).The primary data has been collected using a closed-ended questionnaire based on simple random sampling approach. This study employed the multilayer Perceptron neural network model to envisage the level of job satisfiers towards work commitment. The result from the multilayer Perceptron neural network model displayed with four hidden layer with correct classification rate of 70% and 30% for training and testing data set. The normalized importance shows high value for coworkers, superior satisfaction and communication and which acts as most significant attributes of job satisfiers that predicts the overall work commitment of employees.
Inventario y caracterización morfológica de lagos y lagunas de alta montaña en las provincias de Palencia y León (España)
Authors: Fuentes-Pérez J. F. , Navarro Hevia J. , Ruiz Legazpi J. , García-Vega A.
Published: October 2015

Los lagos y lagunas de alta montaña no son un rasgo típico del paisaje de la Península Ibérica, sino más bien una excepción en el medio natural, por ello su estudio y conservación presenta gran interés. Este trabajo surge con objeto de inventariar y caracterizar un conjunto de diecisiete complejos lagunares ubicados en las provincias de Palencia y León (Cordillera Cantábrica y Sierra de la Cabrera), sin ningún tipo de restricción por tamaño. Así mismo se describen sus cuencas, ligadas con las masas de agua y que determinarán su futura evolución. Entre otros resultados, cabe señalar que, a pesar de su carácter de cabecera, presentan una red hidrológica compleja y variada, denotando la diversidad de estos sistemas. La composición litológica parece incidir significativamente en la profundidad de las unidades, sin embargo la profundidad y dimensiones de las lagunas dependen en gran medida de las características concretas de su morfogénesis. En general, los lagos y lagunas estudiados parecen ser más frágiles ante posibles alteraciones en sus cuencas al compararlas con otros sistemas de mayor tamaño recogidos en diferentes estudios.

Published: October 2015

This paper introduces an approach for formal verification of BPMN models. The incompatible constructs of the BPMN patterns can lead to wrong or incomplete semantics which resulting the behavioral errors such as deadlock and multiple termination. This research is motivated by the need to create a correct business process and in order to generate a more complete formalization of BPMN semantics than existing formalizations. We first introduce the chosen patterns which are the most used in the modelisation of the service-based business processes. Then, we illustrate a definition of the execution semantics of these patterns by using the rules of Max+ Algebra formulas, which have important benefits.

Authors: Yilmaz Serhat , Eken Seher , Kaya Metin Orhan
Published: October 2015

In this paper, vibration analysis of a blade modeled as an anisotropic composite thin-walled beam is carried out. The analytical formulation of the beam is derived for the flapwise bending, chordwise bending and transverse shear deformations. The equations of motion are solved by applying the extended Galerkin method (EGM) for anti-symmetric lay-up configuration that is also referred as Circumferentially Uniform Stiffness (CUS). Consequently, the natural frequencies are validated by making comparisons with the results in literature and it is observed that there is a good agreement between the results. Combined effects of transverse shear, fiber orientation, and rotational speed on the natural frequencies are further investigated.
