THE LESSER ROLE OF SHEAR IN GALACTIC STAR FORMATION: INSIGHT FROM THE GALACTIC RING SURVEY

We analyze the role played by shear in regulating star formation in the Galaxy on the scale of individual molecular clouds. The clouds are selected from the 13CO J = 1–0 line of the Galactic Ring Survey. For each cloud, we estimate the shear parameter which describes the ability of density perturbations to grow within the cloud. We find that for almost all molecular clouds considered, there is no evidence that shear is playing a significant role in opposing the effects of self-gravity. We also find that the shear parameter of the clouds does not depend on their position in the Galaxy. Furthermore, we find no correlations between the shear parameter of the clouds with several indicators of their star formation activity. No significant correlation is found between the shear parameter and the star formation efficiency of the clouds which is measured using the ratio of the massive young stellar objects luminosities, measured in the Red MSX survey, to the cloud mass. There are also no significant correlations between the shear parameter and the fraction of their mass that is found in denser clumps which is a proxy for their clump formation efficiency, nor with their level of fragmentation expressed in the number of clumps per unit mass. Our results strongly suggest that shear is playing only a minor role in affecting the rates and efficiencies at which molecular clouds convert their gas into dense cores and thereafter into stars.
A classification of open Gaussian dynamics

We introduce a classification scheme for the generators of bosonic open Gaussian dynamics, providing instructive diagrams description for each type of dynamics. Using this classification, we discuss the consequences of imposing complete positivity on Gaussian dynamics. In particular, we show that non-symplectic operations must be active to allow for complete positivity. In addition, non-symplectic operations can, in fact, conserve the volume of phase space only if the restriction of complete positivity is lifted. We then discuss the implications for the relationship between information and energy flows in open quantum mechanics.
Quantum versus mean-field collapse in a many-body system

The recent analysis, based on the mean-field approximation (MFA), has predicted that the critical quantum collapse of the bosonic wave function, pulled to the center by the inverse-square potential in the three-dimensional space, is suppressed by the repulsive cubic nonlinearity in the bosonic gas, the collapsing ground state being replaced by a regular one. We demonstrate that a similar stabilization acts in a quantum many-body system, beyond the MFA. While the collapse remains possible, repulsive two-particle interactions give rise to a metastable gaseous state, which is separated by a potential barrier from the collapsing regime. The stability of this state improves with the increase of the number of particles. The results are produced by calculations of the variational energy, with the help of the Monte Carlo method.

Correlates of extinction risk in squamate reptiles: the relative importance of biology, geography, threat and range size

Aim Evaluating the relative roles of biological traits and environmental factors that predispose species to an elevated risk of extinction is of fundamental importance to macroecology. Identifying species that possess extinction-promoting traits allows targeted conservation action before precipitous declines occur. Such analyses have been carried out for several vertebrate groups, with the notable exception of reptiles. We identify traits correlating with high extinction risk in squamate reptiles, assess whether these differ with geography, taxonomy and threats, and make recommendations for future Red List assessments. Location Global. Methods We collected data on biological traits and environmental factors for a representative sample of 1139 species of squamate reptiles. We used phylogenetically controlled regression models to identify general correlates of extinction risk, threat-specific correlates of risk and realm-specific correlates of risk. We also assessed the relative importance of range size versus other factors through multiplicative bivariate models, partial regressions and variance partitioning. Results Range size was the most important predictor of extinction risk, reflecting the high frequency of reptiles assessed under range-based IUCN criteria. Habitat specialists occupying accessible ranges were at a greater risk of extinction: although these factors never contributed more than 10% to the variance in extinction risk, they showed significant interactions with range size. The predictive power of our global models ranged from 23% to 29%. The general overall pattern remained the same among geographical, taxonomic and threat-specific data subsets. Main conclusions Proactive conservation requires shortcuts to identify species at high risk of extinction. Regardless of location, squamate reptiles that are range-restricted habitat specialists living in areas highly accessible to humans are likely to become extinct first. Prioritizing species that exhibit such traits could forestall extinction. Integration of data sources on human pressures, such as accessibility of species ranges, may aid robust and time-efficient assessments of species extinction risk.
Mathematics Teachers’ Use of Ethnomathematics Approach in Mathematics Teaching in Edo State

The study investigated mathematics teachers’ use of ethnomathematics approach to teaching. Descriptive survey research was used with a target population of all mathematics teacher in all public secondary schools in Oredo, Egor and Ikpoba- Okha local government areas of Edo State out of which 121 mathematics teachers in 42 randomly selected public secondary schools were sampled. Fourteen schools each were selected from the three local government Areas by balloting. The instrument for the data collection was ethnomathematics opinion survey questionnaire. Data collected were analysis using descriptive statistics. From the analysis, it was established hat majority of mathematics teachers are using ethnomathematics approach in teaching. Results also showed that there is no significant difference between male mathematics teachers and their female counterparts in their use of ethnomathematics approach to teaching and there is no signifycant difference between mathematics teachers in rural areas and their counterparts in urban areas in their use of ethnomathematics approach to teaching. Recommendation were made. One of which was the national policy on education recommendation of teacher’s students ratio of 1:40 should be strictly adhered to:
Itraconazole prophylaxis for an outbreak of invasive aspergillosis in a hematology ward after hospital construction work

Objective Hospital construction work, among other environmental factors, is a risk factor for invasive aspergillosis (IA). Methods We retrospectively surveyed the incidence of IA in hematology-oncology patients before and during hospital construction and studied the effectiveness of prophylactic oral itraconazole (ITCZ) treatment. We compared the rates of galactomannan (GM)-positive cases and probable IA cases among 224 patients discharged before the start of construction work and among 67 patients hospitalized within two months after the start of the construction work. Results Our results showed that, during the 12 months before the construction work was started, only four patients were GM-positive, and one had a probable diagnosis; in contrast, among patients hospitalized within two months from the start of the construction work, seven patients were GM-positive, and four had a probable diagnosis. Therefore, we started to administer oral ITCZ to 40 patients with hematological diseases. Although the construction work continued, after the ITCZ prophylaxis, no new probable cases of IA were detected. Conclusion From our experience, GM surveillance among hematological patients is necessary during hospital construction work, and the administration of ITCZ to prophylactically prevent IA is suggested upon detection of an increase in GM-positive patients.
Stability of Commercial Xylanases stored singly or Combined with Vitamins and/or Minerals Premix at different Temperatures

| Xylanase is an important feed enzyme that enhances the digestibility of animal feedstocks. Xylanase degrades arabinoxylan, thus improving the nutritive value of feed ingredients. In the present work, a 360-d study was performed to evaluate the effects of different storage forms and temperature on storage stability of exogenous xylanase. Two xylanase products Fibrozyme®M and Hostazym X 250 Microgranulated; were stored as pure forms, with-a vitamin premix, a mineral premix or a vitamin and mineral premix at 4 °C (RF) and 35 °C (R), respectively. Sampling was performed at 45 days intervals. Stability was estimated as the residual of xylanase activity (% of initial) at each sampling point. All interaction and main effects of temperature, time and treatment had a significant (P< 0.05) effect on xylanase enzyme stability except for the product (P> 0.05). When xylanase of different products were stored in different forms at 4 °C, the means of retained activity of Fibrozyme were 90, 98.5, 73 and 63.5% when it was stored singly, mixed with vitamins, minerals or vitamins plus minerals; respectively. For Hostazyme the retained activities were 81.7, 103, 85 and 88%, respectively. When both enzymes were stored at 35 °C; the retained activities of the first were 47%, 94.5%, 82.5% and 57% and those of the second were 61.25%, 106%, 95.5% and 86.5%, respectively for storing singly, mixed with vitamins, minerals or vitamins plus minerals. Results indicated that xylanases mixed with vitamins retained significantly higher (P<0.05) activity compared with those stored in a pure form, mixed with minerals or combined minerals and vitamins. It could be suggested to introduce both xylanases, examined herein, and vitamins premix in one product. More studies are needed to evaluate the effect of different enzyme sources, storage conditions and composition of the enzyme preparation on the stability of the product.
Influence of different tillage systems in physical properties of a distrophic Red Latosol

The tillage systems have the objective to offer an adequate physical conditions in soil for growth, development and productivity of crops. The objective of this study was to evaluate the effect of different soil tillage systems on some physical properties of a distrophic Red Latosol soil (Typic Haplorthox), cultivated with cassava, in the Paraná state, Brazil. The treatments were: No-tillage (the soil was just revolved along the planting lines) – NT; Minimum Tillage (subsoiling at 0.30 m depth, followed by leveling) – MT; and Conventional Tillage (plowing with moldboard plow to the 0.25-0.30 m depth, followed by leveling) CT. In the layers of 0-0.15 and 0.15-0.30 m, soil physical properties i.e soil bulk density (Bd), macroporosity (Mac), microporosity (Mic) and total porosity (Pt) were evaluated. The soil resistance to root penetration (SRP) was evaluated in 0.05 m intervals until the depth of 0.40 m, in two different periods of cassava growth. The results indicated higher values of Bd and lower values of Mac and Pt in NT and MT than in CT system. The air-filled porosity was <10% in MT and NT. The SRP was higher in NT than in CT and MT, with values >2.0 MPa until the depth of 0.25 m. The results of this study suggest that soil physical quality may be restrictive to growth of crops in NT. It may be justified by the higher values of SRP and reduced soil aeration.
Student’s beliefs about using worked–example based video podcast in mathematics courses

The goal of the study is to explain the behavioral, normative and control beliefs of vocational college students about their intentions in using worked –example based video podcast (WEBVP) technology in mathematics courses. The research is based on the framework of the Theory of Planned Behavior (TPB). It was carried out on 110 students of Computer Programming Department of Erzurum Vocational College during the spring semestre of 2014- 2015 academic year. Data were collected by employing a questionnaire form (n=110) containing open-ended and close-ended questions developed by the researcher and semi-structured interviews (n=25). The results showed that the students’ intentions to use WEBVP in mathematics course are under the influence of their behavioral beliefs such as convenience to individual learning, repeatability and usage of advanced technology and their normative beliefs having social support. In addition, the control beliefs in which conceptual structure of mathematics, academic proficiency and individual learning differences are determined to be forcing factors, and the opportunity to reach information, elasticity in space and time and saving of time are determined to be facilitating factors also significantly affect the students’ intentions to use WEBVP.
Effect of air pollution on soluble proteins, structure and cellular material release in pollen of Lagerstroemia indica L. [Lytraceae]

Pollen of Lagerstroemia indica was collected from polluted (SO2, NOx, CO, HC, airborne particulate matter) and less polluted areas of Tehran city, Iran. Some pollen from less polluted areas was exposed to polluted air for 10 and 20 days. To determine the effect of air pollution on proteins, pollen extracts were analyzed by the Bradford method and SDS-PAGE. Study of pollen structure by light and scanning electron microscopy showed that air pollution increased the number of shrunken and fragile pollen. Particle agglomeration and cellular material release were increased in polluted pollen. Total protein content and the staining intensity of protein bands by SDS-PAGE were decreased in polluted pollen.
Pressão arterial de adolescentes de escolas particulares de Fortaleza-CE

Objective: To identify the blood pressure of adolescents in private schools in the city of Fortaleza-CE. Methods: This is a cross-sectional and quantitative study in which 794 adolescents were surveyed - between 12 and 17 years of age - from 14 private schools of that city, in the period from March to September 2007. It was used a questionnaire that contemplated the following characteristics: socio-demographic, blood pressure, body mass index (BMI), physical activity and capillary glucose. Results: It was found that 19.7% of young people had high blood pressure. The male participants had systolic blood pressure (SBP) and diastolic blood pressure (DBP) higher than females (p=0.0001). The investigation found higher values of SBP and DBP in those who were overweight (p=0.0001). Conclusion: The blood pressure was influenced mainly by gender and BMI
The Effects of Diversification Activities on the Technical Efficiency of Organic Farms in Switzerland, Austria, and Southern Germany

The diversification of farms can be a result of multifunctional farming, however, in some cases at the cost of lower farm efficiency. In our paper we investigate the influence of para-agricultural diversification on productivity and the technical efficiency of organic farms in Austria, Switzerland, and Southern Germany. We show the benefits and drawbacks of diversification for organic farms, which go beyond the core agricultural production (para-agriculture). We do this by estimating a Stochastic Frontier (SF) combined with a metafrontier model. The data-set consists of bookkeeping data with 1704 observations in the years 2003 to 2005. Para-agricultural diversification activities have a significant effect on both productivity and technical efficiency of organic farms: The farm output in Austria and Switzerland is positively influenced by diversification, whereas we observe a rather small effect in Southern Germany. On the other hand, diversification can reduce farms’ technical efficiency, as it is the case in Switzerland and Germany. Furthermore, our study confirms previous results that agricultural subsidies significantly influence the technical efficiency of organic farms. We also show expected changes of input use driven by increased farm diversification.
THE ABSOLUTE MAGNITUDES OF TYPE Ia SUPERNOVAE IN THE ULTRAVIOLET

We examine the absolute magnitudes and light-curve shapes of 14 nearby (redshift z = 0.004–0.027) Type Ia supernovae (SNe Ia) observed in the ultraviolet (UV) with the Swift Ultraviolet/Optical Telescope. Colors and absolute magnitudes are calculated using both a standard Milky Way extinction law and one for the Large Magellanic Cloud that has been modified by circumstellar scattering. We find very different behavior in the near-UV filters (uvw1rc covering ∼2600–3300 Å after removing optical light, and u ≈ 3000–4000 Å) compared to a mid-UV filter (uvm2 ≈2000–2400 Å). The uvw1rc − b colors show a scatter of ∼0.3 mag while uvm2−b scatters by nearly 0.9 mag. Similarly, while the scatter in colors between neighboring filters is small in the optical and somewhat larger in the near-UV, the large scatter in the uvm2 − uvw1 colors implies significantly larger spectral variability below 2600 Å. We find that in the near-UV the absolute magnitudes at peak brightness of normal SNe Ia in our sample are correlated with the optical decay rate with a scatter of 0.4 mag, comparable to that found for the optical in our sample. However, in the mid-UV the scatter is larger, ∼1 mag, possibly indicating differences in metallicity. We find no strong correlation between either the UV light-curve shapes or the UV colors and the UV absolute magnitudes. With larger samples, the UV luminosity might be useful as an additional constraint to help determine distance, extinction, and metallicity in order to improve the utility of SNe Ia as standardized candles.
A eficácia dos projectos especiais de urbanismo comercial. Evidências de braga

Este artigo tem como objectivo analisar o processo de implementacao dos programas publicos Procom e Urbcom na cidade de Braga. Estes programas foram concretizados no territorio atraves dos designados projectos especiais de urbanismo comercial, mecanismos peculiares no âmbito das intervencoes de regeneracao urbana das areas comerciais em Portugal por disponibilizarem fundos integrados para a modernizacao dos estabelecimentos comerciais, reabilitacao do espaco publico e animacao comercial. Para analisarmos a eficacia de ambos os projectos elaboramos 50 inqueritos a empresarios que aderiram aos projectos e quatro entrevistas a stakeholders com conhecimento acerca dos mesmos. Concluimos que o processo de modernizacao dos estabelecimentos ja estava em curso e ia efectuar-se mesmo sem a adesao aos projectos, tal como tambem ja se encontrava a decorrer a reabilitacao das ruas do centro da cidade, tendo a contribuicao do Procom e Urbcom sido reduzida. As accoes promocionais realizadas pela associacao comercial foram efemeras e concentradas em poucos eixos comerciais, o que restringiu a sua capacidade de produzir impactos positivos. De forma geral, pelo que foi dito acima e porque nao foram capazes de minimizar as ameacas externas, concluimos que ambos os projectos foram ineficazes na regeneracao do tradicional centro de comercio da cidade de Braga.

Firms as Realizations of Entrepreneurial Visions

In the debate on why firms exist, the question of who chooses between firms and markets and on what basis is rarely addressed. This paper argues that the choice is a core element of the entrepreneurial pursuit of visions or conceptions of business opportunities. To successfully organize resources into the envisioned businesses - be it via firms or markets - resource owners must be coordinated on the entrepreneur's conception of the business and be motivated to perform properly. To solve the dual problem, the organizational form of the firm offers the entrepreneur unique advantages not feasible under the organizational form of markets.

Pathogenicity of entomopathogenic fungi to Ornithodoros erraticus and 1 Ornithodoros moubata ( Acari : Argasidae ) 2 3 4

24 25 The argasid ticks O. erraticus and O. moubata are of great medical and veterinary 26 importance because they are vectors of the African swine fever virus and several species of 27 human relapsing fever borreliae. Biocontrol of these ticks using entomopathogenic fungi has not 28 been previously reported. We examined the pathogenicity to different developmental stages of 29 these two argasids of six strains of the fungal species Beauveria bassiana (strains Bb1764 and 30 Bb2157), Lecanicillium lecanii (strains Ll586, Ll618 and Ll3047) and Tolypocladium 31 cylindrosporum (strain Tc3398). Three strains, Bb1764, Bb2157, and Tc3398, caused in 32 Spanish O. erraticus mean mortality rates between 34.4% and 62% in 14-28 days post33 inoculation. Additionally, Bb2157 also induced in African O. moubata mean mortality rates of 34 31.9%. The remaining strains caused lower mortality rates and were not considered effective. 35 This is the first study in which some strains of entomopathogenic fungi are found to be effective 36 against argasid ticks of the genus Ornithodoros, and its results might justify further efforts 37 towards the application of entomopathogenic fungal strains as anti-argasid biocontrol agents 38 39 40 41 42
