Molecular systematics of some bifurcate hairy sections in Astragalus L. (Fabaceae) as inferred from nuclear and chloroplast DNA sequences

In this study, 38 species belonging to some bifurcate hairy sections of Astragalus L. were analyzed phylogenetically, using nuclear and plastid DNA sequences. Based on our results, Astragalus sect. Dissitiflori DC. with the inclusion of the members of section Erioceras Bunge, formed a monophyletic group. The members of sect. Ornithopodium Bunge and Onobrychoidei DC. were located together within a highly supported monophyletic clade, apart from other sections studied, on the basis of the present molecular data.The positioning of the enigmatic, recently established species, A. juladakensis Maassoumi, within the sect. Dissitiflori was verified. In addition, our results showed that A. pravitzii Podl. , which had been already transferred to sect. Ornithopodium , belongs to the section Dissitiflori . Bangladesh J. Plant Taxon. 23 (2): 223-235, 2016 (December)
A Customer-Oriented Approach to Satisfaction with Public Service Providers. Empirical Findings from a Market Undergoing Liberalization

Unlike the open competition economic sectors where tens, hundreds or even thousands of companies ‘struggle’ to provide consumers not only with services but also with special utility, the regulated markets (power supply, public transportation, public safety etc.) are dominated by a limited number of service providers. Sometimes the situation is pushed to the point where a few companies ‘control’ the market and set the prices. Although the power and gas supply is still ‘dictated’ by the Romanian authorities, the directives of the European Union coerce the government to deregulate the utility sector and liberalize prices. For the companies concerned, this entails a better customer orientation and an adaptation of their services to the customers’ expectations and preferences. From this point forward, the utility suppliers will have to better cope with the public’s various forms of dissatisfaction with prices, performance or communication etc. The authors of the current paper attempt to analyze how some characteristics of the marketing mix of utility providers may contribute to a proper understanding and building satisfaction with two surveyed regional providers. The findings reveal significant management implications which help utility providers better channel their efforts into the proper knowledge of markets and particularly the target segments that they approach.
Organ dose conversion coefficients for external neutron irradiation based on the Chinese mathematical phantom (CMP)

A group of Monte Carlo simulations has been performed for external neutron dosimetry calculation based on a whole-body mathematical model. The Chinese mathematical phantom (CMP) is a mathematical human body model developed based on methods of ORNL (Oak ridge National Laboratory) mathematical phantom series (OMPS), and data from Chinese reference man and reference Asian man. Fluence-to-absorbed dose conversion coefficients of 24 organs and tissues for monoenergetic neutron beams ranging from 10−9 to 102 MeV were calculated using the Monte Carlo code MCNPX. Irradiation conditions include anterior–posterior, posterior–anterior, right lateral, left lateral, rotational, and isotropic geometries. Results for the different organs are compared with those recommended in International Commission of Radiological Protection (ICRP) publication 74 and results obtained based on the visible Chinese human (VCH) phantom. Overall the consistency among the three sets of data was observed, but significant deviations up to 30–50% were also found in the AP, PA and lateral irradiation conditions. Since CMP represents the Chinese population, this work is helpful as a reference to investigate the difference of the neutron induced organ doses due to the anatomical variation between the Chinese and the Caucasians, and that between the average population and an individual.
A simple formula for calculating porosity of magma in volcanic conduits during dome-forming eruptions

We present a simple formula for analyzing factors that govern porosity of magma in dome-forming eruptions. The formula is based on a 1-dimensional steady conduit flow model with vertical gas escape, and provides the value of the porosity as a function of magma flow rate, magma properties (viscosity and permeability), and pressure. The porosity for a given pressure depends on two non-dimensional numbers ε and θ. The parameter ε represents the ratio of wall friction force to liquid-gas interaction force, and is proportional to the magma viscosity. The parameter θ represents the ratio of gravitational load to liquid-gas interaction force and is inversely proportional to the magma flow rate. Gas escape is promoted and porosity decreases with increasing ε or θ. From the possible ranges of ε and θ for typical magmatic conditions, it is inferred that the porosity is primarily determined by ε at the atmospheric pressure (near the surface), and by θ at higher pressures (in the subsurface region inside the conduit). The porosity near the surface approaches 0 owing to high magma viscosity regardless of the magnitude of the magma flow rate, whereas the subsurface porosity increases to more than 0.5 with increasing magma flow rate.
Identification and analysis of instability in non-premixed swirling flames using LES

Large eddy simulations (LES) of turbulent non-premixed swirling flames based on the Sydney swirl burner experiments under different flame characteristics are used to uncover the underlying instability modes responsible for the centre jet precession and large scale recirculation zone. The selected flame series known as SMH flames have a fuel mixture of methane-hydrogen (50:50 by volume). The LES solves the governing equations on a structured Cartesian grid using a finite volume method, with turbulence and combustion modelling based on the localised dynamic Smagorinsky model and the steady laminar flamelet model respectively. The LES results are validated against experimental measurements and overall the LES yields good qualitative and quantitative agreement with the experimental observations. Analysis showed that the LES predicted two types of instability modes near fuel jet region and bluff body stabilised recirculation zone region. The mode I instability defined as cyclic precession of a centre jet is identified using the time periodicity of the centre jet in flames SMH1 and SMH2 and the mode II instability defined as cyclic expansion and collapse of the recirculation zone is identified using the time periodicity of the recirculation zone in flame SMH3. Finally frequency spectra obtained from the LES are found to be in good agreement with the experimentally observed precession frequencies.
Fractional elliptic operators from a generalized Glaeske-Kilbas-Saigo-Mellin transform

We show that the deformation of the canonical spectral triples over the n-dimensional torus which is characterized by a conjectured elliptic operator Dβ = ̸ D(1+ |̸ D|)−β = 1 Γ(β) ∫ ∞ 0 τβ−1e−τ(1+ ̸D2) ̸ Ddτwith β ≥ 0 and by a discrete dimension spectrum with fractional values less than n may be obtained if the elliptic operator is defined by means of the fractional Glaeske-Kilbas-Saigo-Mellin transform. Fractional field theory is a new successful branch of theoretical physics used to treat many important problems in particle physics [3,6,7,10-15,25,26]. This new field is in fact characterized by fractional dimensions and fractional differential operators. In reality, the appealing and attractive concept of fractional dimensions plays a crucial and leading role in almost all branches of sciences since it was first introduced by Mandelbrot about three decades ago [19]. Actually, fractional operators are considered to be an effective tool for describing dynamical systems displaying algebraic scale-invariant properties with non-integer exponent that is relevant in data analysis, dissipation and long-range interactions in space and/or time (memory) that cannot be illustrated using traditional analytic functions and ordinary differential operators. Due to their obvious scale-invariant features, fractional operators provide, in addition, a practical tool for dealing more precisely with complex dynamics having multiple scales, generated in the deep ultraviolet (UV) regime of quantum field theory [13,14]. Fractional elliptic operators were introduced in literature through different contexts [20-23 and references therein] yet most of them were done by hand with no mathematical background. These operators are useful to define non-integer dimensional deformations of the canonical spectral triples (A,H, ̸ D). Ais the commutative C∗algebra of smooth functions over the n-dimensional torus Tn,n ∈ N, H is the Hilbert space of square integrable sections of a spinor bundle over Tn and ̸ D is an unbounded elliptic operator acting on H=L2(M, S) of square-integrable spinors with positive-definite signature specifying the metric and C∞(M)acts on ′H′ by multiplication operators with ∥[ ̸ D, π(x)]∥ = ∥∥∥1radπ(x)∥∥∥∞ , π ∈ C(M). Besides, an algebra of functions defined on a manifold is replaced by an abstract associative pre-C∗algebra A=C∞(M) of smooth functions on an orientable, connected, compact, N-dimensional differentiable unbounded manifold M with respect to the C0-norm acting in H by multiplication operators as follows: ( f1)(x) = f (x)1(x),∀x ∈M [9]. It is notable that fractional dimensions arise in quantum gravity [6] and within the framework of 2010 Mathematics Subject Classification. 26A33, 49S05, 58B10.
Educational Leadership on the Social Frontier

We examined how the federal Promise Neighborhoods program shapes leadership networks and objectives in diverse tribal and urban settings. The program calls for diverse stakeholders to provide families with resources such as parenting workshops, childcare, preschool, health clinics, and other social services that affect learning and development. We focused particularly upon how Promise Neighborhoods planning and development creates new “frontiers of educational leadership. ” We analyzed Promise Neighborhoods planning grant applications—21 that were funded and 21 from tribal settings—as well as interview data and program and community-specific archival data to learn about applicants’ purposes and compositions of partners. These data were analyzed with insights from Burt’s notion of structural holes, which suggests that leadership in “social frontier” spaces is often dependent upon negotiation, entrepreneurship, and relationship brokering. While both urban and tribal applicants were found to have highly diverse compositions of partners, tribal partners were more heterogeneous and separated by greater geographic distances. Additionally, tribal applicants’ stated purposes and goals were tied more closely to local cultures and customs. We note that the sprawling spaces and significant inter- and intracommunity differences of the tribal Promise Neighborhoods ensure that leadership practice in these settings is especially dependent upon negotiation and relationship brokering. As Promise Neighborhoods and other place-based initiatives are developed, diverse networks of leaders will be called to bridge organizational boundaries, cultural differences, socioeconomic differences, and physical distances to develop coherent plans of action for collective “Neighborhoods. ”
Temporal variations of BTX compounds in Bursa/Turkey atmosphere

Ambient concentrations of C2-C12 volatile organic compounds (VOCs) were measured at Bursa, which is the fourth largest city of Turkey. Two measurement campaigns were carried out between September 14 to November 6, 2005 and March 17 to May 10, 2006. Fifty one VOCs were regularly determined in each chromatogram. However, only BTX compounds are discussed in this study. Concentrations of BTX compounds showed well-defined diurnal cycles. Concentrations increased starting at 06:00 am in the morning, reaching to a maximum somewhere between 9:00 to 11:00 am. Then concentration decreased, until the evening rush hour, owing to increasing mixing height during day time. Then concentrations of BTX increased in the afternoon rush hour which extended to 08:00 pm. BTX concentrations remained low throughout the night. High binary correlations between BTX compounds suggest a common source, which are traffic emissions. However, other non-traffic sources were also found to be effective, for benzene in the November to March c.
Influence of early dry season fires on primary production in western Serengeti grasslands, Tanzania

Short-term, i.e. 4-9 weeks aboveground net primary production (ANPP) temporal patterns during the first post-fire year in western Seren-geti National Park, and potential differences in the factors limiting ANPP between burnt and non burnt grasslands were examined and es-tablished. Fire stimulated growth at early post-fire stages, even during the dry season, July-October and led to larger increments in green phytomass compared to the non burnt grassland at the onset of short rains, Octo-ber-December. Further, ANPP in burnt plots correlated well with the ratio leaf/total standing phytomass suggesting that the accumulation of standing dead material can be a limiting factor to ANPP in burnt grass-lands. However, ANPP in burnt plots was unrelated to rainfall contrary to earlier arguments, but reached peak earlier and declined early in the rain season, perhaps due to the interactive effects of fire and grazing in the area. In non burnt plots, the temporal change in ANPP was more related to rainfall availability, at least until mid-growing season. Also, the phytomass structure differed between burnt and non burnt grasslands, and together with litter did not recover to non burnt levels within the first post-fire year. The study has demonstrated that the desire of the fire man-agement program in Serengeti National Park, which is to supply green forage to both migra-tory and resident populations during dry season is being fulfilled.
Managing architectural competitions: Empirical evidence from practices in the UK and Italy

Since project based organizations are a typical configuration in the architecture industry, two streams of research are relevant for architecture practices. (1) Team management, as architecture design and production originate from collaborative networks among multiple actors, but results from empirical studies have been inconsistent regarding which variables are predictive of team performance and project success. (2) Project management, as management in organizing practices has grown in recent years, even if existing research has difficulty with linking performance attributes to specific factors such as organizational form, company culture or strategy. Based on these premises, the paper focuses on architecture competitions which are a currently debated topic and one of the most important rituals to acquire work. The aim is to explore how competitions are part of the practice's business strategy and how teams work on competitions' proposals. We analyse and compare two case studies of middle-sized architectural practices (around 30-40 employees), one in Italy and one in the UK, competing for work through competitions. Preliminary findings suggest that architectural competitions can serve both exploration and exploitation strategies and are based on a collaborative design process.
Epidemiological Characterization of Chikungunya Outbreak in Lahj Governorate, Southern Yemen

Background and Objective: An outbreak of Chikungunya fever was poorly documented in the twenty three countries of the Eastern Mediterranean Region of the World Health Organization. The first case of Chikungunya fever was reported in Northern Yemen in the beginning of January 2011. This paper documents the first outbreak of Chikungunya fever in Southern Yemen and highlights the activities and findings of the epidemiology and laboratory team investigation during the outbreak. Methods: This was a case-series investigation in which the response teams conducted epidemiological and laboratory investigations on suspect cases. The cases identified were line-listed and a data analysis was undertaken regularly to guide the outbreak response. Results: Overall, 234 cases meeting the Chikungunya fever suspected case definition, were reported between 21st March and 8th May, 2012, from 19 areas in Al-Hawtah district, Lahj Governorate, Southern Yemen. Only 30 (12.8%) of the suspected Chikungunya cases underwent laboratory testing and only 13(43.33%) of them were laboratory confirmed as Chikungunya. Suspected Chikungunya cases had fever (100%) and arthralgia and joint swelling were reported in 95% and 64% of the cases, respectively. The overall attack rate was 7.52 cases/1000 populations. All age group and gender were affected. Conclusion: This is the first isolation of Chikungunya virus in Al-Hawtah district of Lahj governorate, Southern Yemen. The risk of expansion of Chikungunya fever to other governorates in Yemen and also to neighboring countries remains considerably high, as many of these governorates and countries are dengue prone, host large number of travelers from abroad and competent vectors for indigenous transmission of both dengue and Chikungunya exist in these countries. The location of this outbreak, in a coastal area of the country, makes the spread of the disease a further possibility.
Spatial Periodicities of Structural Features of the Basement Complex of Southwestern Nigeria Deduced from Auto-Covariance and Power Spectra of Aeromagnetic Data

Structural mapping in the Basement Complex of southwestern Nigeria can be difficult because of the paucity of rock exposures in a terrain that is also difficult to access in places. This paper describes the application of an alternative method of obtaining structural information, involving the computation of autocorrelation functions and power spectra for aeromagnetic profiles. The method was applied to part of Ilesha area, located in the basement complex of southwestern Nigeria. The results reveal the existence of a repetitive pattern in the spatial distribution of the magnetic structure in the rocks along the profiles examined excluding the two located in the northeastern portion. On a regional scale, the periodicities observed have wavelengths of 8.33, 4.12, 2.08, and 0.76 km, respectively. These correspond remarkably with three out of the six peaks observed in the frequency histogram of aeromagnetic lineament spacing in the study area. The success of the method in the study area means that it can also be applied to other areas underlain by Basement Complex rocks where such periodicities can be obscured by irregular or complex features.

Body composition as a determining factor in the aerobic fitness and physical performance of Czech children

Body composition (BC) may be used as a criterion of the actual biological state of children, in other words, their physical state of development. The aim of our study was to determine the interdependence of some body composition variables and aerobic fitness (VO2max.kg-1) and parameters of physical performance, ie. calculated total work (CTW) and maximal power output (MPO) on the treadmill in a group of Czech children and youth. The interdependence between frequently used indicators of aerobic fitness (VO2max.kg-1, CTW, and MPO), and BC (% BF, FFM, BCM and ECM/BCM) were studied in a group of 1235 Czech children (756 boys and 479 girls) aged from 6 to 14 years. Both aerobic fitness and physical performance variables were assessed by means of an incremental treadmill test with a constant slope of 5%. The age dependent initial speed was increased by 1 km.h-1 till subjective exhaustion. Body composition was determined by whole body bioimpedance measurements using a modified prediction equation for children. The percentage of BF was negatively correlated with VO2max.kg-1, and CTW. Both FFM and BCM were positively related to CTW, MPO, and VO2max.kg-1. The ECM/BCM relationship was negatively related to VO2max.kg-1 and CTW. In conclusion, BC is an important determinant of physical performance in the laboratory (treadmill exercise tests) and in the field (running and/or walking tests). The BC parameters significantly influence the variables that could be used for characterisation of aerobic fitness. The results further demonstrate that when oxygen consumption is not feasible, physical performance characteristics together with parameters of BC seem to be a good predictor of aerobic fitness. This may be very helpful in large population studies.
RIGOROUS, A HOMEOPATHIC MEDICINE, EFFECTIVE FOR CONTROLLING APHIDS IN BREAD WHEAT

2 (T2) (Rigorous 1.5% solution @ 1.5 litre + 100 litre of water/acre) revealed minimum aphid population and maximum aphid mortality percentage for all time points. The results showed that aphid population decreased and the mortality rate increased with the passage of time from 24 hour to 7 days. The treatment, T 3(water only) was the least detrimental for the coccinellids predator for all time po ints. There was a positive correlation between aphid population per tiller and number of coccinellids per plant for all durations. Rigorous application resulted in significant increase in grain yield per hectare as compared to control. The results conclude d that Rigorous could be efficiently utilized for controlling aphids in bread wheat in addition to less detrimental effects to the natural enemies of aphids.
A Comparison of US and Korean Consumers: A Cross-Cultural Study of Brand-Related UGC Found in Discussion Boards of Product Review Sites

This study is a partial replication of Fong and Burton’s 2008 study. Fong and Burton (2008) conducted a cross-cultural study comparing Chinese and US Internet users in terms of willingness to engage in information-seeking and information-giving, utilizing Hofstede’s (1980; 1991) individualistic/collectivistic cultural dimension. The current study examines cross-cultural differences in the use of UGC between US and Korean consumers by conducting a content analysis of the discussion boards of six digital camera review sites based in the US and Korea. It content-analyzes 1871 online postings on discussion boards of US-based and Korea-based product review sites. The study adopts Hofstede’s (1980; 1991) individualistic/collectivistic dimension and Hall’s (1981; 1990) cultural contexts (high-context & low-context cultures) as cultural dimensions, and found some cross-cultural differences and similarities between US and Korean Internet users by examining four hypotheses concerning US and Korean Internet users’ willingness to engage in information-seeking, willingness to engage in information-giving, tendency to use implicit communication styles, and tendency to use explicit communication styles.
