Establishment of a protocol for obtention of neuronal stem cells lineages from the dog olfactory epithelium. Pesquisa Veteri- naria Brasileira 30(4):363-372. Departamento de Ciencia Animal, Campus Universitario, Bairro Cibrazen, Bom Jesus, PI 64900-000, Brazil. E-mail: flavioribeiro@ufpi.edu. br A morphological and cell culture study from nasal mucosa of dogs was performed in order to establish a protocol to obtain a cell population committed to neuronal lineage, as a proposal for the treatment of traumatic and degenerative lesions in these animals, so that in the future these results could be applied to the human species. Twelve mongrel dogs of 60-day aged pregnancy were collected from urban pound dogs in Sao Paulo. Tissue from cribriform ethmoidal lamina of the fetuses was collected at necropsy under sterile conditions around 1h to 2h postmortem by uterine sections and sections from the fetal regions described above. Isolated cells of this tissue were added in DMEM/F-12 medium under standard conditions of incubation (5% CO 2 , >37°C). Cell culture based on isolated cells from biopsies of the olfactory epithelium showed rapid growth when cultured for 24 hours, showing phase-bright sphere cells found floating around the fragments, attached on culture flasks. After 20 days, a specific type of cells, predominantly ellipsoids or fusiform cells was characterized in vitro. The indirect immunofluorescence examination showed cells expressing markers of neuronal precursors (GFAP, neurofilament, oligodendrocyte, and III â-tubulin). The cell proliferation index showed Ki67 immunostaining with a trend to label cell groups throughout the apical region, while PCNA immunostaining label predominantly cell groups lying above the basal lamina. The transmission electron microscopy from the olfactory epithelium of dogs revealed cells with electron-dense cytoplasm and preserving the same distribution as those of positive cell staining for PCNA. Metabolic activity was confirmed by presence of euchromatin in the greatest part of cells. All these aspects give subsidies to support the hypothesis about resident progenitor cells among the basal cells of the olfactory epithelium, committed to renewal of these cell populations, especially neurons.
Ovarian development of Caspian roach, Rutilus caspicus, in southern Caspian Sea: A histological and ultrastructural study

The histology and ultrastructure of the ovarian maturation process in Caspian roach, Rutilus caspicus , was studied. A total 170 female specimens were collected from the Gharasoo River, Bandar Turkmen, the southern Caspian Sea to evaluate its maturation cycle. Based on the results, its ovarian follicle’s development could classified into six stages by distinct characteristics. Minimum and maximum diameter of oocytes were recorded in the chromatin-nucleolus and maturation stages as 56.34±3.74 and 918.83±14.82 µm, respectively. The zona radiata was observed from the cortical alveoli stage and its maximum diameter measured in the secondary vitellogenesis stage as 93.11±23.0 µm. Gonadosomatic index (GSI) reached to its peak in mid-March and its sharp drop in the late April showed its spawning period from late March or early April till the end of April. A positive correlation was found between the GSI and HSI in the vitellogenesis stage. The results also revealed Caspian roach as iteroparous synchronous spawner.
The Financial and Operating Performance of Privatized Companies in Turkish Cement Industry

This paper examines the post-privatization performance of privatized companies in the Turkish cement industry. The findings indicate that, when performance criteria for both the state and private enterprises are considered, privatization in the cement industry results in significant performance deterioration. Total value added and the return on investment declines significantly after privatization. This decrease mainly stems from deterioration in asset productivity. The decline in asset productivity, however, is not caused by an increase in capital investment, since postprivatization capital investment did not change significantly. Significant contraction in total employment and an increase in financial leverage after privatization are among the key research findings. Privatization through public offering, gradual privatization and domestic ownership are found to stimulate the financial and operating performance of firms following privatization.
Particle deposit formation during filtration characterisation using ultrasonic waves

Membranes filtration processes are widely used because of their ability to remove particles, colloidal species and micro‐organisms from different liquids feeds. However an inherent process limitation is the membrane fouling due to deposition of suspended matter during filtration. Therefore the understanding of formation and transport properties of particle deposit responsible for membrane fouling is a necessary step to optimize membrane processes. These deposits are non homogeneous, highly porous and very thin (less than 500 μm). Thus, it is necessary to obtain local information in order to analyze and model the basic mechanisms involved in deposit formation and then to further predict process operation. As local parameters such as cake thickness and porosity are hardly reachable with conventional techniques, we propose in this paper the use of an ultrasonic echographic method. In a first step this method is validated on deposits of small glass balls. We show that the porosity and thickness of the deposit.
Rating emotion communication: display and concealment as effects of culture, gender, emotion type, and relationship

Students from a collectivistic (Brazilian, n= 401) and an individualistic (Norwegian, n= 418) culture rated their ability to display and conceal anger, sadness, and anxiety in relation to immediate family, partner, friends, and “other persons. ” Norwegians showed higher display ratings for anger and sadness, and higher concealment ratings for anger and anxiety. Display ratings were much higher, and concealment ratings much lower in relation to close persons than in relation to “other persons. ” A culture x relationship interaction was that Brazilians’ ratings suggested more emotional openness to friends than to family and partner, whereas Norwegians showed the inverse patterns. Gender differences supported previous research by showing higher display and lower concealment ratings, and less differentiation between relationships by females.
Caractérisation structurale et magnétique de nanoparticules de CoPt : mise en évidence de la transition de phase A1 vers L10

Les nanoalliages a base de materiaux ferromagnetiques sont interessants car ils peuvent etre a la base d'une technologie de stockage haute densite innovante. En particulier, l'alliage CoPt presente une phase ordonnee fortement anisotrope. Dans ce travail, des nanoparticules de 1,5 a 5 nm de diametre ont ete synthetisees dans un bâti ultra-vide par « Mass Selected Low Energy Cluster Beam Deposition » puis deposees avec une faible energie et enrobees dans une matrice de carbone amorphe. Apres une caracterisation des couches d'agregats en matrice de carbone par microscopie electronique en transmission (MET) conventionnelle, la structure des nanoparticules est etudiee par MET en mode haute-resolution et comparee a des simulations d'images. Cette approche originale permet de mettre en evidence la mise en ordre des nanoparticules et de quantifier le parametre d'ordre d'une particule unique. La diffraction des rayons X en incidence rasante (GIXRD) permet, grâce a des modelisations d'arriver a la meme conclusion: apres un recuit sous ultra-vide de 2 h a 650° C, les nanoparticules d'alliage CoPt en matrice de carbone presentent une transition de phase A1 vers L10 sans trace de pollution ni de coalescence. Une etude magnetique des memes echantillons par magnetometrie a SQUID et dichroisme magnetique des rayons X (XMCD) permet de confirmer que les nanoparticules, apres un tel traitement thermique, subissent un changement de proprietes magnetiques allant dans le sens d'une mise en ordre chimique meme pour des tres petites tailles (de diametre 1,8 nm).
Habitat use and population dynamics of brown bears (Ursus arctos) in Scandinavia

Assessment of large-scale habitat suitability is essential in planning the management of the expanding brown bear (Ursus arctos) population in Scandinavia. We built a quantitative habitat model using utilization distributions (UD) estimated with the kernel home range method for 73 female bears in two study areas in Scandinavia. Prior analysis of the habitat composition of home ranges ensured that the large-scale variables used in the model selection were biologically relevant. Bears were found mainly in forested areas with a low level of human influence relative to surrounding human activity. A strong correlation between the predicted habitat suitability and the distribution of hunter-killed bears indicated good performance of the model. The quantitative habitat model provides a helpful tool for bear management, as it can be used to identify and visualize suitable habitats for brown bears, as well as to estimate the potential future distribution of the currently expanding population in Scandinavia.
Effects of different agricultural wastes and botanical on root knot nematode (Meloidogyne spp) on okra (Abelmoschus esculentus L. Moench)

The effect of agricultural wastes and a botanical on root knot nematode (Meloidogyne spp) on okra (Abelmoschus esculentus L. Moench) was investigated in pot experiment. The experiment was laid out in a completely randomized design with five treatments each replicated five times. The treatments included: sawdust, oil palm sludge, cassava peels, bitter leaf powder, carbofuran plus untreated control. All the treatments except oil palm sludge and nematicide were applied at the rate of 20 g each. Oil palm sludge was applied at the rate of 20 ml while the nematicide at 3.0 g ai per plant. The plants were inoculated with 2000 nematode eggs (Meloidogyne spp.) three weeks after emergence. Treatments and fertilizer were applied one and three weeks after inoculation respectively. Eight weeks after treatment application, the experiment was terminated and the following collected; fresh and dry shoot weight, plant height, number of leaves, number of galls, population of nematode eggs in the roots and nematode population in the soil. Results obtained indicated non-significant difference between the treatments in the parameters recorded except plants treated with bitter leaf and nematicide in some cases. Generally, results from bitter leaf were better and compared favourably with the nematicide treated plants.
GENETIC VARIATION AND CHARACTER ASSOCIATION OF SEED . YIELD AND ITS COMPONENT CHARACTERS IN FENUGREEK

An evaluation of 72 lines of fenugreek (Trigonella foenum-graecum L.) has shown existence of high variability. for seed yield, number of pods per plant and protein content while low variability was recorded for days to flowering and number of grains per pod. High broad sense heritability and genetic advance estimates were obtained for protein content and number of pods per plant. Based upon the correlations and path coefficient analysis it was concluded that number of pods per plant, test weight and plant height were the most important traits as they exerted positive direct effect as well as showed positive correlation with seed yield.
Multi-Temporal Remote Sensing of Landscape Dynamics and Pattern Changes in Dire District, Southern, Ethiopia

Science and reporting information needs for monitoring dynamics in land-cover over time prompted research, and made operational, a wide variety of change detection methods utilizing multiple dates of remotely sensed data. Improper land use results in land degradation and decline in agricultural productivity. Hence, in order to get maximum benefits out of land, proper utilization of its resources is inevitable. The present study was aimed at identifying the land cover changes in the study area in the last 25 years and determines the extent and direction of change that has occurred. The study made use of Landsat TM 1986 and 2011 Remote Sensing Satellite Image for analysis to determine the extent and pattern of rangeland change. The results of the landuse/landcover change detection showed that in the last 25 years, 3 major changes were observed, grass land and open shrub land resource significantly decreased at a rate of 17.1 km 2 / year and 12 km2/year respectively. On the other hand in 25 years dense bushland, open bush land, dense shrub land and cultivated land has shown increment in size at a rate of 0.23 km 2 /year, 13.5 km 2 /year, 6.3 km 2 /year and 0.2 km 2 /year, respectively within 25 years. The expansion of unpalatable woody species significantly reduced the rangeland size and availability of grasses. The consequence of the decrease in herbaceous biomass production might result in high risk of food insecurity in the area unless proper interventions are made in time.
A New Biased Model Order Reduction for Higher Order Interval Systems

This paper presents a new biased method for order reduction of linear continuous time interval systems. This method is based on the Stability equation method, Pade approximation and Kharitonov’s theorem. The higher order interval system is represented by four Kharitonov transfer functions using the Kharitonov’s theorem, and then reduced order models are obtained by the general form of the Stability equation method and Pade approximation. The Stability equation method is used to obtain a reduced order denominator polynomial while the Pade approximation is used for reduced order numerator coefficients. This method generates a stable reduced order model if the original higher order interval system is stable. The proposed method is illustrated with the help of typical numerical examples considered from the literature, and these are compared with well-known methods to show the efficacy of the proposed method.
Motion by curvature of a three-dimensional filament: similarity solutions

We systematically classify and investigate fully three-dimensional similarity solutions to a system of equations describing the motion of a filament moving in the direction of its principle normal with velocity proportional to its curvature, ν = κn, where n is the principle normal and κ the curvature of the filament. Such formulations are relevant to superconducting vortices and disclinations.
An Empirical Investigation of the Determinants of User Acceptance of Electronic Exchanges (Case Study: Buying and Selling Section of Active Companies of Iran's Textile Industry)

Electronic commerce is being increasingly developed as the modern phenomenon of business world. But this fact should be considered that in spite of all benefits electronic commerce brings about, it should not be observed as a purpose. Certainly necessary actions must be taken with regard to accepting of electronic commerce for applying and facilitating of it in the organization. The purpose of this research is designing a comprehensive model for acceptance of electronic exchanges technology in textile industry. The statistical population consists of all employees of buying and selling section of active companies of Iran's textile industry. We have applied random sampling method in this research. In order to test the conceptual model, structural equations' model has been used that the results of it demonstrate acceptance and confirmation of all studied factors . Amount of goodness indexes (AGFI= 0.93, GFI= 0.96) shows suitability of the model.
Temporal variation and cross-sectional differences of accounting conservatism in emerging countries

Prior research finds that accounting conservatism has increased over time in developed countries. In this paper, we examine the time-series extent and shift of accounting conservatism in emerging countries over the period 2000-2012. We also analyse differences in conservatism level across countries, regions, legal regimes and industries. In addition, we examine the impact of size, market-to-book and leverage on the degree of conservatism at firm level. We use a set of measures to assess the degree of conservatism. These include changing time-series properties of profitability, earnings, cash flows, accruals components, asymmetric timeliness, Market-to-Book ratio and Khan and Watts' (2009) C-score. We find that the degree of conservatism declined during the period between 2000 and 2007 and increased over the period 2007-2012. In addition, we find significant differences in accounting conservatism between common-law and code-law countries, across regions and industries.
The formation of direct collapse black holes under the influence of streaming velocities

We study the influence of a high baryonic streaming velocity on the formation of direct collapse black holes (DCBHs) with the help of cosmological simulations carried out using the moving mesh code {\sc arepo}. We show that a streaming velocity that is as large as three times the root-mean-squared value is effective at suppressing the formation of H$_{2}$-cooled minihaloes, while still allowing larger atomic cooling haloes (ACHs) to form. We find that enough H$_{2}$ forms in the centre of these ACHs to effectively cool the gas, demonstrating that a high streaming velocity by itself cannot produce the conditions required for DCBH formation. However, we argue that high streaming velocity regions do provide an ideal environment for the formation of DCBHs in close pairs of ACHs (the "synchronised halo" model). Due to the absence of star formation in minihaloes, the gas remains chemically pristine until the ACHs form. If two such haloes form with only a small separation in time and space, then the one forming stars earlier can provide enough ultraviolet radiation to suppress H$_{2}$ cooling in the other, allowing it to collapse to form a DCBH. Baryonic streaming may therefore play a crucial role in the formation of the seeds of the highest redshift quasars.
Computer Attitude of Teachers in Relation to Their Level of Instruction

ICT is not only the backbone of the Information Age, but also an important catalyst for inducing educational reforms that could transform students from passive recipients of knowledge to pioneers of the learning process. Today, technology is an integral learning tool for promoting the social, linguistic, and cognitive development of children of all ages. To achieve the goal of a technological revolution in education however, it is imperative that both teachers and students develop the necessary knowledge and skills sought in this digital age. The present descriptive research aimed to compare computer attitudes of teachers employed at different levels of instruction in an attempt to discern whether the curriculum and activities included at a particular teaching stage had any influence on their computer attitudes. The findings of the study revealed the fact that primary and secondary school teachers showed a significant difference in their computer attitudes, while those of schools and colleges were comparable in terms of each of the variables considered. These results could provide important implications for enhancing the curriculum across the different teaching stages in an attempt to bring about the necessary attitudinal changes in teachers toward the use of computers in a technology driven age.
Ownership Concentration and R&D Investments? VariationsBrought by Family Control in Taiwan

This study finds that ownership concentration has a positive impact on R&D investments up to a critical point, after which the impact is reversed. Further, the study indicates that family control has a moderating effect on the nonlinear relationship between ownership concentration and R&D investments. More specifically, family-controlled firms are influenced by ownership concentration to a lower extent than non-family controlled firms. Consistent with most prior studies, this study shows that shareholders of a family-controlled firm are involved in the long-term decisions of the firm, and may thus invest in R&D innovation to seek long-term profit maximization in certain situations.
PROFILE OF YOUNG ELITE HANDBALL PLAYERS ACCORDING TO PLAYING POSITIONS

The aim of this study was to examine the morphological characteristics and functional abilities of the junior men's handball team of Serbia, as well as possible differences between the four positions on the team (goalkeeper, wing players, guards and pivot). In the statistical analysis basic parameters were calculated, and then one factor ANOVA test was conducted and post-hoc analysis of variance. Statistically significant difference (p <0.05) was found in body weight, body height, the amount of fat, percentage share of fat and muscle tissue and muscle-fat ratio in athletes. Wing players are distinguished from most other players in the morphological characteristics of the body. The value of their body height, weight and BMI, muscle mass and subcutaneous fat were significantly lower compared to players in other positions. With high values of body mass and amount of fat and bone tissue, the highest homogeneity of morphological profile was found between the goalkeep)
Using nanosphere lithography for fabrication of a multilayered system of ordered gold nanoparticles

New modification of nanosphere lithography has been realized to obtain multilayered systems of ordered gold nanoparticles (NP). NP have been formed using vacuum deposition of 5.60-nm layer of gold on ionic etched multilayered regular coating consisted of several layers of 200-nm polystyrene spheres. Optical study shows that spectra of NP depend on their thickness and may be changed by heat treatment. Increasing the NP thickness within the 5.20-nm range leads to a shortwave displacement of the plasmon resonance peak position, while the longwave shift is observed in 20.60-nm range. Heat treatment of NP brings narrowing and displacement of spectral bands, rising the extinction. It has been supposed that variation of the NP shape is the most substantial factor for changes of optical properties in the 5.20 nm thickness region, while electromagnetic coupling between NP in different layers becomes more important for thicknesses larger than 40 nm. Optical properties inherent to the obtained system of NP can be tuned by changing the polystyrene spheres diameter, extent of etching, thickness of gold layer and with the heat treatment. It may be used in design of nanophotonic devices.
Deterrence from self-protection measures in the ‘market model’ of crime: dynamic panel data estimates from employment in private security occupations

Private individuals and entities invest in a wide variety of market-provisioned self-protection devices or services to mitigate their probability of victimization to crime. However, evaluating the effect of such private security measures remains understudied in the economics of crime literature. Unlike most previous studies, the present analysis considers four separate measures of private security: security guards, detectives and investigators, security system installers, and locksmiths. The effects of laws allowing the concealed carrying of weapons (an unobservable precaution) are also evaluated. Given that Ehrlich’s ‘market model’ suggests private security is endogenous to crime, the analysis relies primarily on dynamic panel data methods to derive consistent parameter estimates of the effect of self-protection measures. The relationship between self-protection and UCR Part II Index offense (arrest) data are also considered in order to provide exploratory evidence on the interaction between publicly and privately provisioned crime deterrence efforts.
