OXIDATIVE/ANTIOXIDATIVE STATUS OF BLOOD PLASMA IN BITCHES WITH MAMMARY GLAND TUMOURS

The aim of the study was the estimation of oxidative/antioxidative status of bitches with mammary gland tumours by the determination of lipid peroxidation intensity, concentration of glutathione and β-carotene as well as total antioxidant capacity (TAC) in blood plasma. The experiment was carried out on 18 bitches with spontaneously occurring mammary gland tumours (12 with malignant tumours and 6 with benign tumours) and 6 clinically healthy controls. The intensity of lipid peroxidation did not differ significantly among the examined groups of animals. The concentration of glutathione was higher in both neoplasm groups than in healthy bitches, but the differences were not significant. The concentration of β-carotene in plasma was similar in cases of malignant and benign tumours, but was significantly lower (P<0.05) than in healthy controls. TAC of plasma was lower in bitches with tumours than in healthy animals. Significant difference was noticed between malignant tumours and controls (P<0.01). In conclusion, the alterations in antioxidative status occur in bitches with mammary gland tumours, suggests the presence of general antioxidative stress. A necessity of more frequent sample collection for the detection of dynamic changes in peroxidation process revealing the intensity of oxidative stress in bitches suffering from mammary gland tumours should be considered.
Measuring and forecasting quality in English hospitals

Hospital performance metrics, often in the form of risk‐adjusted hospital mortality rates, are increasingly being made available in the public domain to compare hospitals. Despite the proliferation of these metrics, uncertainty remains regarding their validity and reliability given the noise surrounding their underlying measures. The paper considers a quality measure of hospital performance developed by McClellan and Staiger which smooths within hospitals and over time, while remaining computationally straightforward. The McClellan and Staiger method improves on others by incorporating different measures of outcome, eliminating systematic bias arising from the heterogeneous mix of hospital outputs and the noise that is inherent in other measures of quality. The technique also allows the forecasting of future quality. Using English hospital episode statistics for the years 2000–2005 for acute myocardial infarction and hip replacement, we use this technique to return quality measures based on hospital fixed effects estimated from yearly cross‐sectional patient level data, and vector auto‐regressions estimated over time, which then combine information from different time periods and across conditions to produce robust hospital quality measures. Our results suggest that this method is well suited to measure and predict provider quality of care in the English setting.
Radiometric and seismic study of Chidvinskaya kimberlite pipe (Arkhangelsk diamondiferous province, North of the East European Craton, Russia)

Surface geophysical measurements were carried out on Chidvinskaya diamond pipe of the Arkhangelsk diamondiferous province (North of the East European Craton, Russia). Geophysical measurements included a high-precision gamma-spectrometric survey, radon emanation survey in soil air, and microseismic sounding method. Radiometric measurements were used to found radioactivity anomalies of the surface layer over the Chidvinskaya pipe which could be a result of impact of the kimberlite body on a host medium. Deep structure of the kimberlite pipe and host medium was imaged by means of microseismic sounding method. Results indicate that the pipe appears as a high-velocity body. The host medium is low-velocity that is typical for rocks with excessive fissuring. Increased values of total gamma-ray radiation of near surface layer are observed within the pipe contour and exceeded the background values by 2-4 times. Anomalous radon emanation in the soil air was found at the pipe boundaries. According to the microseismic sounding data near-contact zone is a gas-penetrable structure with excessive fissuring. The results of the used methods are in good agreement with each other. The proposed complex of methods has allowed to identify the pipe distinctive feature.
Sedimentological evidence for rotation of the Early Permian Nambucca block (eastern Australia)

The Early Permian tectonic history of eastern Australia led to the formation of several orogenic curvatures termed the New England oroclines. How these oroclines formed is a controversial issue that is crucial for understanding the paleo-Pacific subduction dynamics at the Gondwanan margin and the formation of curved orogenic belts in general. Here we present new constraints on the role of vertical-axis block rotations in the New England oroclines using paleocurrent indicators from the core of the oroclinal structure (the Nambucca block). Focusing on the lower sedimentary succession within the Nambucca block (Kempsey beds), we recognize two facies associations. Facies association A comprises conglomerate and gravelly sandstone with minor sandstone, collectively interpreted as the deposits of coastal to subaqueous marine fans. Facies association B is made of heterolithic intervals of sandstone and mudrock that are interpreted as the products of deposition on a marine continental slope. Younging directions suggest that facies association A represents the basal part of the succession that is overlain by the more heterolithic association. The paleogeographic position of the Nambucca block, in conjunction with its stratigraphy and geochronological provenance, suggests that it formed as part of a large, deep-marine backarc basin. Paleocurrent and paleoslope directions are north to northeast, inconsistent with the present understanding of the Permian paleogeography that involved an approximately north-south–oriented continental margin (in present coordinates) and an eastward-deepening marine surface. This supports previous paleomagnetic interpretations of counterclockwise rotations of adjacent blocks. In conjunction with recently published structural, paleomagnetic, and geochronological constraints, our data suggest that counterclockwise rotations occurred between 285 and 275 Ma in the course of the formation of the southern segment of the New England oroclines (Manning orocline). The rotation incorporated both continental and marine plate margin segments of eastern Gondwana, thereby deforming the deep backarc basin that is partially represented by the Nambucca block. Our data thus provide constraints both on the kinematics and on the timing of the much-debated southern segment of the New England oroclines.
RT-002-05 Simultaneous Embedding of Outerplanar Graphs , Paths , and Cycles

Let G1 and G2 be two planar graphs having some vertices in common. A simultaneous embedding of G1 and G2 is a pair of crossing-free drawings of G1 and G2 such that each vertex in common is represented by the same point in both drawings. In this paper we show that an outerplanar graph and a simple path can be simultaneously embedded with fixed edges such that the edges in common are straight-line segments while the other edges of the outerplanar graph can have at most one bend per edge. We then exploit the technique for outerplanar graphs and paths to study simultaneous embeddings of other pairs of graphs. Namely, we study simultaneous embedding with fixed edges of: (i) two outerplanar graphs sharing a forest of paths and (ii) an outerplanar graph and a cycle.
Factors explaining the use of management accounting practices in Malaysian medium-sized firms

Purpose – The purpose of this paper is to investigate factors that affect the use of management accounting practices (MAPs) in Malaysian medium-sized firms in manufacturing sector. Design/methodology/approach – A quantitative research design involving the use of postal questionnaire was carried out to investigate the influences of key contingent factors on MAPs. The survey was conducted to 500 Malaysian medium-sized firms in manufacturing sector which elicited 110 useable responses. Findings – The results indicates that size of the firm, intensity of market competition, commitment of owner/manager of firm and advanced manufacturing technology have significant influences on the use of certain MAPs. Thus the research provides support for a contingency-based explanation for the use of MAPs and identifies new variable such as commitment of owner/manager as one of a key factor that affect the extent of use of MAPs in smaller firms. Research limitations/implications – The research focused on medium-sized firms .
Mediterranean Conference on Information Systems ( MCIS ) 2011 THE CREATIVITY OF VIRTUAL DESIGN TEAMS : AN EXPLORATORY CASE STUDY

Creativity is a topic of interest across numerous disciplines and areas of study. While in engineering design some stages of the design process have become highly dependent upon technology and Computer-Aided Design (CAD) tools, scholars in the field of management claim that the impetus for virtual teamwork calls for research as to how the new, boundaryless virtual arrangements alter some of the management practices built surrounding the physically-collocated workplace. In this paper, we reveal a knowledge gap on how creativity is influenced in the virtual design context. In our quest to start bridging this gap, we pursued an exploratory case study with a student-based virtual design team project, known as the European Global Project Realization (EGPR). Thirty-nine interview extracts from most participants in the EGPR provided us with insights into the nature of the project, the participants’ perceptions of creativity, and their experience of designing in virtual teams. The qualitative data collected from these interviews were triangulated by observation and document review and were analysed thematically, in line with our theoretical model derived from the literature review. In all, our study contributes to the current body of knowledge by identifying some of the factors that influence creativity in virtual design teams (i.e. motivation, experience/training, subgrouping, diversity and knowledge, supervision, industrial partners, project importance, Information and Communication Technologies (ICTs)).
Diurnal cycling: observations and models of the upper-ocean response to diurnal heating, cooling, and wind mixing. Technical report

A diurnal cycle occurs when solar heating warms and stabilizes the upper ocean. This limits downward penetration of turbulent wind mixing so that air-sea fluxes of heat and momentum are surface trapped during midday. The central problem is to learn how the trapping depth DT (mean depth value of the diurnal temperature and velocity response) is set by the competing effects of wind mixing and surface heating. In this data set, the diurnal range of surface temperature Ts was observed to vary from 0.05 < Ts < 0.4 C, with most of the day-to-day variability attributable to variations of wind stress. Wind mixing causes a pronounced asymmetry of the Ts response by limiting the warming phase to only about half of the period that the surface heat flux is positive. The associated wind-driven current, the diurnal jet, accelerates downwind during the morning and midday. It is turned into the wind by the Coriolis force during early evening and is often erased by the following morning.
Hotspots of tropical land use emissions: patterns, uncertainties, and leading emission sources for the period 2000–2005

This paper presents a spatial dataset of greenhouse gas emissions from agriculture, forestry and other land use (‘AFOLU’), covering the Tropics (incl. extra-tropics in South America and Africa) and years 2000-2005. This is a combination of several different published spatial (and non-spatial? ) datasets for individual sources and different greenhouse gases (CO2 from deforestation; CO2, N2O and CH4 from fires; soil C loss and, N2O from cropland soils; soil C loss, N2O, and CH4 from rice paddies; CO2 from wood harvesting; N2O and CH4 from livestock). Although no novel data is presented here, an added value of combining different data sources can be justified. Using respective greenhouse-warming potentials for N2O and CH4, all data is converted to
Anti-inflammatory activity of methanol extract isolated from stem bark of Albizia julibrissin

SUMMARY Albizia julibrissin (AJ) has been used widely as a traditional medicine. In macrophages nitric oxide(NO) is released as an inflammatory mediator and has been proposed to be an importantmodulator of many pathophysiological conditions including inflammation and carcinogenesis. Inthis study we have examined the NO inhibition effect of 85% methanol extracts of AJ in mousemacrophage. Lipopolysaccharide (LPS) has been reported to induce production of NO. Extracts ofAJ (1, 10, 100 μg/ml) suppressed nitric oxide production in LPS-stimulated (100 μg/ml) mouse(C57BL/6) macrophages and analyzed by ELISA. In addition, it also attenuated the expression ofinflammatory products like Interleukin-6 (IL-6), cyclooxygenase-2 (COX-2), and inducible NOS(iNOS) as assessed by immunoblotting with specific antibodies. These results suggest that 85%methanol extracts of AJ would be useful in inflammatory diseases.Key words: Albizia julibrissin; Nitric oxide; IL-6; Cyclooxygenase-2 INTRODUCTION The stem bark of Albizia julibrissin DURAZZ. (Leguminosae) is recorded in the Chinese Pharm-acopoeia as an anti-inflammatory agent, andspecified to treat injuries from falls and removecarbuncles (The Pharmacopoeia Committee ofPeople’s Republic of China, 1995). It is well knownas sedative drug for treating skin ulcers, wounds orswelling and pain of the lungs (Zhang, 2005). Macrophage activation is known to play animportant role in the inflammatory process(Medzhitov and Janeway, 1997a; Beutler 2000) andproduce potent pro-inflammatory cytokines suchas tumor necrosis factor (TNF)-α and interleukin(IL)-6 which induce inflammation and recruit otherimmune cells, e.g., neutrophils and T lymphocytes(Medzhitov and Janeway, 1997b). Although thesepro-inflammatory cytokines are beneficial to thehost defense, they can also trigger pathologicalconditions when expressed in excess. 4) For example,massive stimulation of macrophages after a severeGram-negative bacterial infection leads to excessiveproduction of pro-inflammatory cytokines and thedevelopment of fatal septic shock syndrome, andmultiple organ failure (Parrillo, 1993; Beutler, 1995)and activate pro-inflammatory genes. In addition,higher levels of pro-inflammatory cytokines are
Iterative approach to modeling subsurface stormflow based on nonlinear, hillslope-scale physics

Soil water transport in small, humid, upland catchments is often dominated by subsurface stormflow. Recent studies of this process suggest that at the plot scale, generation of transient saturation may be governed by threshold behavior, and that transient saturation is a prerequisite for lateral flow. The interaction between these plot scale processes yields complex behavior at the hillslope scale. We argue that this complexity should be incorporated into our models. We take an iterative approach to developing our model, starting with a very simple representation of hillslope rainfall-runoff. Next, we design new virtual experiments with which we test our model, while adding more structural complexity. In this study, we present results from three such development cycles, corresponding to three different hillslope-scale, lumped models. Model1 is a linear tank model, which assumes transient saturation to be homogeneously distributed over the hillslope. Model2 assumes transient saturation to be heterogeneously distributed over the hillslope, and that the spatial distribution of the saturated zone does not vary with time. Model3 assumes that transient saturation is heterogeneous both in space and in time. We found that the homogeneity assumption underlying Model1 resulted in hillslope discharge being too steep during the first part of the rising limb, but not steep enough on the second part. Also, peak height was underestimated. The additional complexity in Model2 improved the simulations in terms of the fit, but not in terms of the dynamics. The threshold-based Model3 captured most of the hydrograph dynamics (Nash-Sutcliffe efficiency of 0.98). After having assessed our models in a lumped setup, we then compared Model1 to Model3 in a spatially explicit setup, and evaluated what patterns of subsurface flow were possible with model elements of each type. We found that Model1 tended to generate relatively smooth, steady state-like spatial patterns. Model3 generated more complex patterns, in which lateral flow could be concurrently increasing and decreasing in different parts of the hillslope. We realize that the concepts proposed in this manuscript do not represent the only way in which nonlinear dynamics may be implemented in a model of subsurface stormflow. However, we believe that development of new model structures and the subsequent confrontation of model results with existing preconceptions will lead to a better understanding of subsurface stormflow and catchment runoff dynamics.
ICT integration & the role of school leadership: perceptions of head teachers of secondary schools in Quetta Pakistan

A BSTRACT : The study figure outs perceptions of secondary school head teachers about ICT integration in teaching and learning in schools in Pakistan with focus on Balochistan Province. This was a qualitative study with having eight head teachers as research participants while interviews, informal talks and focused group discussion were used as data collection tools. It is observed from the findings that most of the head teachers had positive perceptions about integration of ICTs into day to day teaching and learning practices. In addition the head teachers although revealed many hindrances in the way of integration of ICT into teaching and learning practices but there existed a significant optimistic approach, at the end of schools’ head teachers, for having considered many enablers for promoting ICT integration in teaching and learning. Their effective leadership role was found to be the man enabler in this regard.
Chinese Short Text Summary Generation Model Integrating Multi-Level Semantic Information

Short text information is less, and short text comprehension abstract generation is currently a hot and difficult issue. We proposed an understanding-based short text summary generation model that combines multi-level semantic information. We improved the structure of encoder in the framework of encoder-decoder which consists of self-attention mechanism and selective network to focuses on the multi-level semantic information. Then our model fully exploits highlevel global semantics and shallow semantic information of internal words of the text, and organically fuses the hidden state of the decoder and the original through two different attention mechanisms. The high-level and shallow semantic information adaptively provide the decoder with a syntactic semantic vector with abstract characteristics, so that the decoder can more accurately focus on the core content of the article. This paper selects the LCSTS data set for model training and testing. The experimental results show that compared with Seq2Seq, Seq2Seq with standard Attention, and Transformer model, the proposed model generates a Chinese short text summary with higher quality and performs better evaluation value in ROUGE.
Requerimientos energéticos de ovinos de pelo en las regiones tropicales de Latinoamérica. Revisión

requirements have not been determined to the same extent as those of wool breeds. Due to the environmental conditions of the tropical regions (climate, quality and availability of feedstuffs), it is reasonable to hypothesize that energy requirements and efficiency of utilization of metabolizable energy (ME) may be different between hair and wool breeds of sheep. Information available on hair sheep shows a large discrepancy regarding energy requirements. Based on available literature data for female sheep, ME requirement for maintenance (ME m ) was 419±129 kJ/ kgBW 0.75 (mean ± standard deviation) and for the male 388±123 kJ/kg BW 0.75 . The requirement of net energy for gain (NE g ) ranged from 8.75 to 14.06 kJ/g (11.63±1.86 kJ/g). The efficiency of ME utilization for maintenance (k m ) and gain (k g ) were 0.66±0.02 and 0.42±0.04, respectively. This review indicated also that information is scarce for adult ewes at different physiological stages (maintenance, lactation, or pregnancy). More work is required regarding estimates of nutrient requirements of hair sheep in order to develop adjustments to existing nutrition models to predict animal’s response under the conditions prevailing in the tropics (animal type, environment and feedstuffs available).
Preliminary Results of Marine Electromagnetic Sounding with a Powerful, Remote Source in Kola Bay off the Barents Sea

We present an experiment conducted in Kola Bay off the Barents Sea in which new, six-component electromagnetic seafloor receivers were tested. Signals from a powerful, remote super-long wave (SLW) transmitter at several frequencies on the order of tens Hz were recorded at the six sites along a profile across Kola Bay. In spite of the fact that, for technical reasons, not all the components were successfully recorded at every site, the quality of the experimental data was quite satisfactory. The experiment resulted in the successful simulation of an electromagnetic field by the integral equation method. An initial geoelectric model reflecting the main features of the regional geology produced field values that differed greatly from the experimental ones. However, step-by-step modification of the original model considerably improved the fit of the fields. Thereby specific features of the regional geology, in particular the fault tectonics, were able to be corrected. These preliminary results open the possibility of inverse problem solving with more reliable geological conclusions.
Information Systems Design Theory for Location-Based Educational Services in Informal Learning Environments

Mobile technologies are deeply embedded in the daily lives of young people. The ubiquity, portability and functionality of these devices present new opportunities for enriching learning. Yet, to date there has been little theory development to guide the application of location-based technologies (LBT) in informal learning environments. To address this gap, we propose to (1) develop an IS design theory for the application of LBTs for education in cultural institutions, (2) pioneer the use of advanced combinatorial methods to improve the technical design process, and (3) instantiate the resulting IS design theory within two leading Australian cultural institutions. The findings will inform policy and the future use of LBT for education
Classical Flutter and Active Control of Wind Turbine Blade Based on Piezoelectric Actuation

The aim of this article is to analyze classical flutter and active control of single-cell thin-walled composite wind turbine blade beam based on piezoelectric actuation. Effects of piezoelectric actuation for classical flutter suppression on wind turbine blade beam subjected to combined transverse shear deformation, warping restraint effect, and secondary warping are investigated. The extended Hamilton’s principle is used to set up the equations of motion, and the Galerkin method is applied to reduce the aeroelastic coupled equations into a state-space form. Active control is developed to enhance the vibrational behavior and dynamic response to classical aerodynamic excitation and stabilize structures that might be damaged in the absence of control. Active optimal control scheme based on linear quadratic Gaussian (LQG) controller is implemented. The research provides a way for rare study of classical flutter suppression and active control of wind turbine blade based on piezoelectric actuation.
