HPLC Enantioseparation of Phenylcarbamic Acid Derivatives by Using Macrocyclic Chiral Stationary Phases

Abstract The HPLC by using chiral stationary phases based on macrocyclic antibiotics, dimethylphenyl carbamate cyklofructan 7 and β-cyclodextrin in terms of polar-organic separation mode (mobile phase methanol/acetonitrile/acetic acid/triethylamine) were used for enantioseparation of alkoxy derivatives of phenylcarbamic acid. The effect of the analyte structures on the efficiency of enantioseparation was investigated. The most suitable stationary phase was teicoplanin aglycone, where the separations of the enantiomers were obtained (the resolution value from 0.65 to 2.90, depending on the structure of the analyte). Significant effect on the resolution of the enantiomers has position of alkoxy substituent in the hydrophobic part of the molecule. The enantiorecognition was achieved for 3-alkoxysubstituted derivatives.
Lifting harmonic morphisms II: tropical curves and metrized complexes

In this paper we prove several lifting theorems for morphisms of tropical curves. We interpret the obstruction to lifting a finite harmonic morphism of augmented metric graphs to a morphism of algebraic curves as the non-vanishing of certain Hurwitz numbers, and we give various conditions under which this obstruction does vanish. In particular we show that any finite harmonic morphism of (non-augmented) metric graphs lifts. We also give various applications of these results. For example, we show that linear equivalence of divisors on a tropical curve C coincides with the equivalence relation generated by declaring that the fibers of every finite harmonic morphism from C to the tropical projective line are equivalent. We study liftability of metrized complexes equipped with a finite group action, and use this to classify all augmented metric graphs arising as the tropicalization of a hyperelliptic curve. We prove that there exists a d-gonal tropical curve that does not lift to a d-gonal algebraic curve. This article is the second in a series of two.
Bioextraction of Cu (II) Ions from Acid Mine Drainage by Bacillus Thuringiensis

In this study, biosorption of Cu and Mn ions from Sarcheshme copper mine wastewater by a locally available bacterium, Bacillus Thuringiensis, was investigated in batch mode. Optimum amounts for various parameters such as contact time, pH, initial ion concentration, biosorbent dosage and temperature were determined. In the first 30 minutes, most of Cu and Mn ions were removed by the sorbent. Optimum pH and temperature were determined to be 6 and 308 ৹ K. The experimental data were fitted to both Langmuir and Freundlich adsorption models. Desorption studies showed that bacterial biomass can be eluted by 1M HCL solution and reused in five biosorption-desorption cycles.
An exploratory study of the contextual meaning and consequences of empowerment in project teams

Empowerment means different things to different individuals. The factors that engender feelings of empowerment and the consequences that ensue are thus multifarious. Using the Critical Incident Technique (CIT) in semi-structured interviews with project participants in Hong Kong, the contextual meaning and consequences of empowerment are explored. Two broad categories of meanings were ascribed to the concept “empowerment” and related to “what individuals or teams feel or experience” and “what organisations or leaders do”, confirming the extant literature’s dichotomous conceptualisation of empowerment into the structural and psychological perspectives. Positive and negative consequences of empowerment and disempowerment were evident. The need to capture the different individual conceptualisations of empowerment in the implementation of empowerment initiatives is shown and that a contextual fit is essential for empowerment to take place.
Measurement of total sound energy density in enclosures at low frequencies

Many acoustic measurements rely on determining the total sound energy in an enclosure; and this quantity is usually estimated by measuring the mean square pressure at a number of discrete positions. Almost 30 years ago it was shown theoretically that the normalised spatial variance of the total sound energy density (potential and kinetic) is one third of the normalised spatial variance of the potential energy density (the mean square pressure) in a reverberant sound field above the Schroeder frequency. About ten years later this prediction was confirmed experimentally. However, until recently measurement of the total sound energy density (in air) has required an elaborate arrangement based on finite different approximations using at least four matched pressure microphones; therefore the method has never come into use. However, with the advent of a three‐dimensional particle velocity transducer it has become somewhat easier to measure total rather than only potential energy density in a sound field. This p.
Teacher and Student Learning in the Workplace : The Impact of Performance Tests

JALT2002 AT SHIZUOKA 325 CONFERENCE PROCEEDINGS (teachers and a group of students), classroom observations, surveys (teachers and students), and documents (including teachers’ materials and students’ performance tests), the study delineates how EFL teachers interact with their colleagues to improve students’ communication skills in English in this school context. This study implies that changing assessment would be effective in promoting teacher and student learning. However, without school culture improvement it is difficult to sustain teacher and student learning.
Consumers' choices towards Eco-Fashion

This study aims to research which factors affect consumers’ choices regarding eco-fashion. In order to research these factors, G-Star’s green fashion marketing campaign Raw for the Ocean was used as a case study. This research took the form of a survey executed among millennials living in the Netherlands from August 2014 until August 2016. The timeframe reflects the period that the campaign was running. The sample was collected by snowball sampling in online spaces and random selection on the streets of Amsterdam. Three models were used to for this study, which are the attitude- behavior model, the eco-fashion involvement model and the campaign involvement model. Furthermore, was studied if the campaign had changed consumer’s attitude and behavior regarding the brand, environmental sustainability and eco-fashion. According to the results affected consumers’ gender, age, fashion attitude/ involvement, environmental attitude/ involvement and ecofashion attitude consumers’ eco-fashion choices. Older consumers within the millennial generation, make more positive choices regarding eco-fashion than younger consumers within generation. Females find eco-fashion more important and are more eco-fashion involved than men. Furthermore, has a high score regarding environmental attitude/ involvement, fashion attitude/involvement and eco-fashion attitude a positive effect on ecofashion choices.
Higher Education, Real Income And Real Investment In The Selected OIC Members: Evidence From ARDL And Panel Data Approaches

Higher education, through increasing the human capital stock of individuals, improves productivity and therefore contributes to economic growth. From economic point of view, this type of expenditure is considered as a long-run investment which increases growth rate and forms a higher capacity of human capacity. The implication is that a dynamic relationship between growth rates of education, income and investment can be implemented in a specific time path. This paper employs ARDL and Panel Data modeling to test the causal relationship between real income, real investment and human capital using data for the 16 selected OIC members over the period 1980-2005. The empirical results approve a long-run effect of human and physical investments. The results also imply a crucial rate of human capital which will play in the future developments of the OIC countries
Forecasting the Volatility of Australian Stock Returns

This article develops multivariate factor models for forecasting volatility in Australian stocks. We suggest estimation procedures for approximate factor models that are robust to jumps when the cross-sectional dimension is not very large, and also work with volatility measures that have been constructed so that they contain no jump components. Out-of-sample forecast analysis shows that multivariate factor models of volatility outperform univariate models, but there is little difference between simple and sophisticated factor models.
Interactive effects of depth and marine protection on predation and herbivory patterns

ABSTRACT: The establishment of marine protected areas (MPAs) worldwide has shown thatclosure of areas to fishing results in major changes in the structure of marine ecosystems. Theremoval of high-order consumers by fishing has both direct and indirect effects that can lead toimportant changes in the strength of trophic interactions. Although the effects of marine protec-tion on biological interactions are beginning to be understood, our knowledge is largely restrictedto shallow-water assemblages. However, depth gradients are also characterised by significantdifferences in the intensity of trophic linkages, and these may be interacting with any effectsderived from protection. In this study, the individual and combined effects of depth and marinereserve protection on predation and herbivory were determined across 3 regions in the NWMediterranean (Catalunya, Mallorca and Menorca) using juvenile urchins and palatable algae asbioassays. Marine protection did not strongly influence fish herbivory, which generally decreasedwith depth. We found no evidence of depth-related changes in predation rates or the size ofpredatory fishes, but there was a strong effect of protection on predation rates that was onlyconsistently observed across regions in shallow water (5 m depth), but not at greater depths(15 and 30 m). This increase in predation of sea urchins within MPAs in shallow waters can haveimportant community-wide consequences, as herbivorous sea urchins are commonly most abun-dant in these shallow habitats and predator−urchin interactions have important cascading effectson algal communities.KEY WORDS: Marine reserves · Sea urchins · Macroalgae · Mediterranean Sea · Fish herbivory ·

A new method for detection of cyclic circadian genes using order restricted inference

Identi cation of periodic patterns in gene expression data is important for studying the regulation mechanism of the circadian system. The information available is often given only by one or two cycles. Consequently, the number of observations is not enough to t certain models, such as Fourier's models, properly. Some authors have already developed procedures or algorithms among which the JTK CYCLE algorithm is the most popular one. We propose a new method to identify cyclic gene expressions based on euclidean and circular order restricted inference. Validation of the method is made through real data sets and simulations. Moreover, we compare the results obtained by the method with other detecting methods developed in the literature.
Role of vegetation in sustaining large‐scale atmospheric circulations in the tropics

The focus of this paper is the role of rain forests in large-scale atmospheric circulations. The significance of this role is investigated by studying the response of the tropical atmosphere to a perturbation in the state of vegetation (deforestation) over three regions: the Amazon, Congo, and Indonesia. A theory is developed to relate tropical deforestation and the resulting changes in the large-scale atmospheric circulation. Field observations and numerical simulations support the argument that tropical deforestation reduces the total net surface radiation, including terrestrial and solar forms. However, the energy balance at the land-atmosphere boundary dictates that for equilibrium conditions, any reduction in net surface radiation has to be balanced by a similar reduction in the total flux of heat, including sensible and latent forms. Since these fluxes supply heat as well as entropy from the forest into the atmospheric boundary layer, a reduction in the total flux of heat reduces the boundary layer entropy. In a moist atmosphere, that satisfies a quasi equilibrium between moist convection and radiative forcing, the equilibrium temperature profile is uniquely related to the boundary layer entropy. Under such conditions, large-scale deforestation reduces boundary layer entropy relative to the surroundings, cools the upper troposphere, and results in subsidence, divergent flow in the boundary layer, and weakening of the large-scale circulation. These changes are simulated using a simple linear model of atmospheric flow. The comparison of the model predictions with observations of atmospheric circulations over the Amazon, Congo, and Indonesia suggests a significant role for vegetation in maintaining large-scale atmospheric circulations in the tropics.

2D Mixed Convection Viscous Incompressible Flows with Velocity-Vorticity Variables

Mixed convection viscous incompressible fluid flows, under a gravitational system, in rectangular cavities are reported using the unsteady Boussinessq approximation in velocity-vorticity variables. The results are obtained using a numerical method based on a fixed point iterative process to solve the nonlinear elliptic system that results after time discretization; the iterative process leads to the solution of uncoupled, well-conditioned, symmetric linear elliptic problems for which efficient solvers exist regardless of the space discretization. Results with different aspect ratios A up to Grashof numbers Gr = 100000 and Reynolds numbers Re = 1000 for the lid driven cavity problem are reported. The validation of the results is given through mesh size and time-step independence studies.
Highlights of the MAGIC AGN program

MAGIC is a system of two Cherenkov telescopes designed to perform observations of gamma rays with energies from about 50 GeV to tens of TeV. A low energy threshold and an excellent low energy performance make it a powerful instrument for studies of high energy processes in Active Galactic Nuclei (AGN). The MAGIC Collaboration dedicates about 40% of the telescopes' time to such observations, both monitoring of known emitters, and Target of Opportunity observations of flaring events. In this presentation we will discuss the recent highlights of the MAGIC AGN program. In particular, multi year monitoring of radio galaxies, such as M87, and strong peculiar blazars, such as PG 1553+113, will be presented together with new discoveries based on the Target Of Opportunity program.
Effect of the interactions and environment on nuclear activity

We present a study of the prevalence of optical and radio nuclear activity with respect to the environment and interactions in a sample of SDSS galaxies. The aim is to determine the independent effects of distinct aspects of source environment on the triggering of different types of nuclear activity. We defined a local density parameter and a tidal forces estimator and used a cluster richness estimator from the literature to trace different aspects of environment and interaction. The possible correlations between the environmental parameters were removed using a principal component analysis. By far the strongest trend found for the active galactic nuclei (AGN) fractions, of all AGN types, is with galaxy mass. We therefore applied a stratified statistical method that takes into account the effect of possible confounding factors like the galaxy mass. We found that (at fixed mass) the prevalence of optical AGN is a factor 2–3 lower in the densest environments, but increases by a factor of � 2 in the presence of strong oneon-one interactions. These effects are even more pronounced for star-forming nuclei. The importance of galaxy interactions decreases from star-forming nuclei to Seyferts to LINERS to passive galaxies, in accordance with previous suggestions of an evolutionary time-sequence. The fraction of radio AGN increases very strongly (by nearly an order of magnitude) towards denser environments, and is also enhanced by galaxy interactions. Overall, the results agree with a scenario in which the mechanisms of accretion into the black hole are determined by the presence and nature of a supply of gas, which in turn is controlled by the local density of galaxies and their interactions. A plentiful cold gas supply is required to trigger star-formation, optical AGN and radiatively-efficient radio AGN. This is less common in the cold-gas-poor environments of groups and clusters, but is enhanced by one-on-one interactions which result in the flow of gas into nuclear regions; these two factors compete against each other. In the denser environments where cold gas is rare, cooling hot gas can supply the nucleus at a sufficient rate to fuel low-luminosity radiatively-inefficient radio A GN. However, the increased prevalence of these AGN in interacting galaxies suggests that this is not the only mechanism by which radiatively-inefficient AGN can be triggered.
OVERBORROWING SYNDROME

This paper compares the equilibrium dynamics of an economy facing an aggregate collateral constraint on external debt to the dynamics of an economy facing a collateral constraint imposed at the level of each individual agent. The aggregate collateral constraint is intended to capture an environment in which foreign investors base their lending decisions predominantly upon macro indicators as opposed to upon individual abilities to pay. Individual agents do not internalize the aggregate borrowing constraint. Instead, in this economy a country interest-rate premium emerges to clear the financial market. The central finding of the paper is that the economy with the aggregate borrowing limit does not generate higher levels of debt than the economy with the individual borrowing limit. That is, there is no overborrowing in equilibrium. JEL classification: F4.
Computational analysis of oligosaccharide conformations – methodological development, applied studies, and design of glycomimetics

Carbohydrates are the most abundant class of biomolecules. Besides their roles as structural elements and energy storage, they are involved in signaling and recognition processes. Their functions and activities depend on their preferred conformations. The software GLYGAL was developed to perform conformational studies of oligosaccharides using a genetic algorithm tailored for carbohydrates. The new method was applied to the highly branched exopolysaccharide of Burkholderia cepacia . The results show that its heptasaccharide repeating units assume a well defined conformation, stabilized by steric interactions between consecutive units. Furthermore, GLYGAL was used to calculate favorable conformations of histo-blood group antigens. The compounds were then fitted in the binding site of the surface protein of the norovirus VA387 strain and their binding affinity was estimated by molecular dynamics and Glide scoring, giving insights into the interaction patterns involved in norovirus infection. Finally, the mimetic properties of thioglycosidic and selenoglycosidic derivatives of the ABH antigens were studied by conformational and dockings studies, indicating potentially bioactive derivatives with increased resistance to hydrolysis. In conclusion, the computational methodologies developed during this study were successfully used, together with existing methods, for the investigation of natural carbohydrates and the rational design of glycomimetics.
Predictors of Complain Behaviour among Mobile Telecommunication Network Consumers

This research paper sought to empirically determine the predictors of consumer complain behaviour. High prevalence of anomalies with mobile telecommunication network services without a lasting solution emphasized the significance of the present study. Hawkins, Best, & Coney (2004) consumer complain behavioural framework was used as the study’s theoretical background. It was a quantitative study which employed a cross-sectional survey. A total of 385 respondents within Festac town in Nigeria were selected stratifiedly for the study. Descriptive analysis showed that 64.9% of the respondents are passive while 35.1% are active complainers. Regression analyses revealed that six demographic variables explained 4.9% variance on complain behaviour while dissatisfaction explained additional 10% variance on complain behaviour. It further indicated that three control measures were significant, with dissatisfaction (β=-.33, p <.001), religion (β=.12, p <.05) and level of income (β=.11, p <.05). Dissatisfaction is an insubvertable factor of complain behaviour regardless of consumers’ religious affiliation and level of income. Firms should try to alleviate dissatisfaction, encourage active complain, and pay more attention to consumers’ religiosity and level of income since these variables influence complain behaviour.
