Investigation of the Essential Oils of Bidens pilosa var. minor, Bidens alba and Flaveria linearis

Abstract Essential oils of fresh plant parts of Bidens pilosa var. minor (Bl.), Bidens alba (L.) DC. (Tribus Heliantheae, Asteraceae) and Flaveria linearis Lag. (Tribus Helenieae, Asteraceae) were obtained by hydrodistillation and analyzed by GC, GC/MS and HPLC. Forty-three compounds were identified in the oils of B. pilosa var. minor and B. alba, which represents 83–94 % of the total components detected. Qualitatively, the compositions of the two oils were similar. In addition to the usual terpenes (α-pinene, β-caryophyllene, β-copaene, germacrene D), three polyacetylenic compound were identified in the oils of each species. In the aerial parts of both B. pilosa and B. alba, 1-phenylhepta-1,3,5-triyne (PHT) was the most abundant component of the oils (30–50%). The other two polyacetylenes were 1-phenylhept-5-ena-1, 3-diyne and 7-phenylhept-2-ena-4,6-diynyl acetate. The latter, which was absent in flower and leaf oils, was predominant in the root oils of both plants. The root oil of B. alba also contained three eugenol derivatives that together accounted for more than 20% of the oil. Two could be identified as eugenol isobutyrate and 1'-isobutyryloxy-eugenol isobutyrate. Thirty components were identified from the different plant parts of Flaveria linearis Lag. This represented 92–94% of the total components of the oil. The oils from the aerial organs of F. linearis were mainly composed of terpenes (α-pinene, myrcene, limonene, (E)-β-ocimene); however, 2-(but-3-en-1-ynyl)-5-(penta-1,3-diyn-1-yl)-thiophene was also an abundant component of the oils from both the flowers and the leaves. In contrast, the root oil of F. linearis consisted mainly of thiophenes. Four thiophenes were identifed: 5-(but-3-en-1-ynyl)-2,2′-bithiophene and 2,2′-5′,2″-terthiophene, were major constituents. 2-(But-3-en-1-ynyl)-5-(penta-1,3-diyn-1-yl)-thiophene and 5′-methyl-5-(but-3-en-1-ynyl)-2,2′-bithiophene, were minor components of the root oil.
Resource allocation model for grid computing environment

Grid computing is a collection of heterogeneous resources that is highly dynamic and unpredictable. It is typically used for solving scientific or technical problems that require a large number of computer processing cycles or access to substantial amounts of data. Various resource allocation strategies have been used to make resource use more productive, with subsequent distributed environmental performance increases. The user sends a job by providing a predetermined time limit for running that job. Then, the scheduler gives priority to work according to the request and scheduling policy and places it in the waiting queue. When the resource is released, the scheduler selects the job from the waiting queue with a specific algorithm. Requests will be rejected if the required resources are not available. The user can re-submit a new request by modifying the parameter until available resources can be found. Eventually, there is a decrease in idle resources between work and resource utilization, and the waiting time will increase. An effective scheduling policy is required to improve resource use and reduce waiting times. In this paper, the FCFS-LRH method is proposed, where jobs received will be sorted by arrival time, execution time, and the number of resources needed. After the sorting process, the work will be placed in a logical view, and the job will be sent to the actual resource when it executes. The experimental results show that the proposed model can increase resource utilization by 1.34% and reduce waiting time by 20.47% when compared to existing approaches. This finding could be beneficially implemented in cloud systems resource allocation management.
Exploration of Attitudes and Experiences of Young Adults Who Do and Do Not Attend College

Personality traits, attitudes, and behavioral intentions of high school seniors prior to attending or not attending institutions of higher education were explored. Because of this age-group’s risk level, variables assessed included historical social/cultural factors, internal/contextual factors, and lifestyle factors potentially associated with violence experiences. Participants were seniors at 24 Kentucky high schools who voluntarily completed surveys. A year later, 2,073 reported whether they attended a 4-year institution (n = 1,038), a 2-year institution (n = 341), or did not attend college (n = 694). The 4-year college attendees reported significantly more protective factors and significantly fewer violence risk factors in high school than peers attending 2-year institutions or not attending college. The 2-year college students largely resembled nonattendees across variables in high school. Traits, behaviors, and attitudes/beliefs occurring prior to young adults’ postsecondary years may not only have potential for predicting post-high school choices but also vulnerability to violence experiences.
Study of the diffusive properties of extracellular matrix gels used in 3D cultures

The extracellular matrix (ECM) hinders diffusion in both tissues and hydrogels used in 3D cultures. However, how geometric and non-geometric ECM properties contribute to diffusion hindrance remains poorly understood. To address this question, the effective diffusivity D of FITC-dextrans with molecular weight (Mr, 4-70 kDa) spanning the physiological range of signaling factors was measured in a panel of acellular ECM gels with an optical macroscopic assay. Gels included reconstituted basement membrane/Matrigel, fibrin and type I collagen, and exhibited an average pore size much larger than any dextran size. Unexpectedly, a decay of D with Mr following a power-law with an exponent that matched that predicted by the Stokes-Einstein law in all gels (D ~ Mr-1/3, r2=0.99) was observed, revealing that hindered diffusion is dominated by nongeometric viscous factors. This law predicted that Matrigel and fibrin exhibited similar viscosities, which was confirmed with microrheology measurements by atomic force microscopy. Moreover, gels with the lowest D exhibited diffusion hindrance comparable to the extreme physiologic hindrance of brain tissue, which has a typical pore size much smaller than ECM gels. In contrast, diffusion hindrance in sparse ( /=3 mg/ml) are suitable tissue surrogates in terms of macromolecular diffusion. Additionally, it is unknown to what extent current 3D culture protocols provide physiologic oxygen tension conditions. To address this limitation, oxygen tension was measured within the acellular or cellularized ECM gels with A549 cells, and analyzed in terms of oxygen diffusion and consumption. Oxygen diffusivity in acellular gels was up to 40% smaller than that of water, and the lower values were observed in the denser gels. In 3D cultures, physiologic oxygen tension was achieved after 2 days in dense (>/=3 mg/ml) but not sparse gels, revealing that the latter gels are not suitable tissue surrogates in terms of oxygen distribution. In dense gels, a dominant effect of ECM composition over density in oxygen consumption as observed. All diffusion and consumption data were used in a simple model to estimate ranges for gel thickness, seeding density and time-window that may support physiologic oxygen tension. Thus, critical variables for oxygen tension in ECM gels were identified, and a model to assess initial values of these variables was introduced, which may short-cut the optimization step of 3D culture studies.
Study of Uranium-Plutonium Carbide-Based Fuel Simulating High Burnup

Carbide-based fuels simulating high burnup were prepared by addition of inactive fission product elements. They contained fission product phases of the UMoC/sub 2/ and U/sub 2/RuC/sub 2/ type, and a rare-earth oxide phase. The thermal conductivity of the material is within the range observed for carbide-based fuels free of fission products. The diffusion of plutonium was considerably enhanced by the addition of fission products. The solid fission product swelling rate of a carbide-based fuel was estimated to be 0.5% per at. % burnup.
Immersion and Presence in Virtual Reality to Alleviate Anxiety Disorder

Mediated communication has become essential as the current development of technology advances. Virtual reality as an audiovisual technology with the ability to simulate a virtual environment similar to the environment in the real world plays a vital role in mediating communication. On the other hand, nowadays, issues about mental health, especially anxiety disorder, spread vastly and become a public concern. This paper aims to see how virtual reality as a medium of communication can reduce anxiety disorders by creating ambient co-presence. The method used was meta-synthesis with a meta-aggregation approach to get comprehensive results. The research found that two main factors exist in virtual reality, namely immersion and presence, which are important factors in mediated communication. These two factors can create ambient co-presence, so they can be applied to reduce mental illness, namely anxiety disorder.
PECVD synthesis of ZnO/Si thin film as a novel adsorbent for removal of azithromycin from water samples

ABSTRACT In the current study, ZnO/Si thin film was prepared through a plasma-enhanced chemical vapour deposition (PECVD) method and used for the elimination of azithromycin (AZM) from various real samples. Some specs about the structure and morphology of the ZnO/Si thin film were systematically examined utilising approaches such as X-ray diffractometry (XRD), X-ray photoelectron spectroscopy (XPS), and Scanning electron microscopy (SEM). The adsorption of AZM on the ZnO/Si thin film was accomplished under various statuses that are equilibrium time = 45 min, adsorbent dose = 0.025, pH solution = 7.0, and primary AZM concentration = 15 mg L−1. Four models were utilised to monitoring the adsorption kinetic of AZM onto ZnO/Si thin film: pseudo-first order (PFO), pseudo-second order (PSO), Elovich (E) and intraparticle diffusion (ID) models. Equilibrium data were ﬁtted to Langmuir (L), Freundlich (F), Temkin (T) and Redlich-Peterson (R-P) isotherm models. The elimination efficiency of AZM via ZnO/Si thin film was evaluated in three real samples. Finally, it should be noted that AZM loaded on the adsorbent could be easily desorbed with 0.1 mol L−1 HNO3 and the adsorbent showed good reusability for adsorption of the studied drug.
PREDICTING RETURNS FOR GROWTH AND VALUE STOCKS: A FORECAST ASSESSMENT APPROACH USING GLOBAL ASSET PRICING MODELS

The present study tests the forecasting strength of widely used asset pricing models, using monthly stock returns of two style-based, large-cap US growth and value index funds for 1993 – 2015. Global variables are added to the models to test the global linkage impact. As we impose a positive forecast returns constraint, there is a considerable reduction in the root mean squared error (RMSE), providing significant economic implications. RMSE of constrained models for non-negativity restriction outperforms the unconstrained models improving them by an average of 17%. As evidenced by the forecasting power measured by RMSE, we found the value stocks to be more predictable with lower overall RMSE when compared to growth stocks. The global models provide better forecast for growth stocks, whereas there are mixed implications for value stocks. The Global Carhart consistently ranks as one of the best models for both growth and value stocks.
Compressible Turbulence Measurements in a Supersonic Boundary Layer Including Favorable Pressure Gradient Effects.

Abstract : The effect of a favorable pressure gradient on the turbulent flow structure in a Mach 2.9 boundary layer (Re/m approx. 1.5 x 10(exp 7)) is investigated experimentally. Conventional flow and hot film measurements of turbulent fluctuation properties have been made upstream of and along an expansion ramp. Upstream measurements were taken in a zero pressure gradient boundary layer 44 cm from the nozzle throat in a 6.35 cm square test section. Measurements are obtained in the boundary layer, above the expansion ramp, 71.5 cm from the nozzle throat. Mean flow and turbulent flow characteristics are measured in all three dimensions. Comparisons are made between data obtained using single and multiple-overheat cross-wire anemometry as well as conventional mean flow probes. Conventional flow measurements were taken using a Pitot probe and a 10 degree cone static probe. Flow visualization was conducted via imaging techniques (Schlieren and shadowgraph photographs). Results suggest that compressibility effects, as seen through the density fluctuations in the Reynolds shear stress are roughly 10% relative to the mean velocity and are large relative to the velocity fluctuations. This is also observed in the total Reynolds shear stress; compressibility accounts for 50 - 75% of the total shear. This is particularly true in the favorable pressure gradient region, where though the peak fluctuation intensities are diminished, the streamwise component of the mean flow is larger, hence the contribution of the compressibility term is significant in the Reynolds shear.
Synthesis and Properties of Polyimides from Bis[4-(Aminophenoxy)phenyl] Ether and Aromatic Dianhydrides Having Various Numbers of Phenylene Units

Aromatic polyimides PI-3e-PMDA and PI-3e-m ( m = 0-4 ) with 3 ether linkages per monomer unit were prepared from bis[4-(4-aminophenoxy)phenyl] ether ( 1 ) and various tetracarboxylic dianhydrides, pyromellitic dianhydride ( PMDA ), 3,3’4,4’-biphenyltertacarboxylic dianhydride ( DA-0 ), 3,3’’4,4’’- p -terphenyltertacarboxylic dianhydride ( DA-1 ), 3,3’’’4,4’’’- p -quarterphenyltertacarboxylic dianhydride ( DA-2 ), 3,3’’’’4,4’’’’- p -quinquephenyltertacarboxylic dianhydride ( DA-3 ), and 3,3’’’’’4,4’’’’’- p sexiphenyltertacarboxylic dianhydride ( DA-4 ), by a conventional two-step procedure that included ring-opening polymerization in NMP and subsequent thermal cyclic dehydration. The polyimides were characterized by wide angle X-ray diffraction, differential scanning calorimetry (DSC), thermogravimetry (TG), and dynamic mechanical analysis (DMA), and compared on the basis of the number ( m ) of phenylene units. PI-3e-PMDA and PI-3e-m ( m = 0-4 ) had glass transition temperatures ( T g ) at 280 °C and 210-230 °C, respectively, and T g values were not dependent on m . The storage modulus ( E ’ ) of PI-3e-m decreased at about 200 °C, after which a rubbery plateau resion was seen, followed by a further decrease at about 330 °C. The DMA results for the annealed PI-3e-PMDA and PI-3e-m ( m = 0-4 ) were also compared and discussed on the basis of m
Assessment of seasonal variation in physico-chemical characteristics of a lentic waterbody of Bhopal, India

The present study was conducted with an aim to assess the seasonal variation and nutrient status of a lentic water body (Lower lake) of Bhopal, India. Different variables involving water temperature (W.T), Secchi transparency (TRN), pH, total dissolved solids (TDS), conductivity (CON), total alkalinity (T.A), dissolved oxygen (DO), chlorides (CL), total hardness (TH), orthophosphate (PO4) and nitrate (NO3-N) were examined using the standard methodology of APHA (2005). Significant seasonal variation was observed in Secchi transparency which ranged from 27 cm to 83 cm, chlorides (29 mg/l to 58 mg/l, dissolved oxygen (1.6 mg/l to 9.2 mg/l), phosphate (1.76 mg/l to 2.9 mg/l) and nitrate (0.98 mg/l to 3.57 mg/l). Our results confer that the water body is undergoing nutrient enrichment especially littoral sites due to direct influx of untreated sewage from surrounding urban settlements which has resulted in the deterioration of water quality of the lake. Pearson correlation analysis was employed to determine the relationship among water parameters which revealed both significant positive and negative trends.
Return and Volatility Transmission between World-Leading and Latin American Stock Markets: Portfolio Implications

This study uses the BEKK-GARCH model to examine the return-and-volatility spillover between the world-leading markets (USA and China) and four emerging Latin American stock markets over the global financial crisis of 2008 and the crash of the Chinese stock market of 2015. Regarding return spillover, our findings reveal a unidirectional return transmission from Mexico to the US stock market during the global financial crisis. During the crash of the Chinese stock market, the return spillover is found to be unidirectional from the US to the Brazil, Chile, Mexico, and Peru stock markets. Moreover, the results indicate a unidirectional return transmission from China to the Brazil, Chile, Mexico, and Peru stock markets during the global financial crisis and the crash of the Chinese stock market. Regarding volatility spillover, the results show the bidirectional volatility transmission between the US and the stock markets of Chile and Mexico during the global financial crisis. During the Chinese crash, the bidirectional volatility transmission is observed between the US and Mexican stock markets. Furthermore, the volatility spillover is unidirectional from China to the Brazil stock market during the global financial crisis. During the Chinese crash, the volatility spillover is bidirectional between the China and Brazil stock markets. Lastly, a portfolio analysis application has been conducted.
Family Communication Patterns and Adolescent Sexual and Reproductive Health: Experiences from Coastal Communities in Ghana

A good understanding of human growth and development helps in the smooth transition of an individual from one stage to another. One of such stages is adolescence, which presents a lot of challenges as well as opportunities. There are differences in the extent to which families encourage conversation, the extent to which they demand conformity to family values as well as the extent to which families pass down strongly held family values from one generation to another, regarding changes that occur during adolescence. The study examines Parent-Child Communication Patterns between parents and adolescents in coastal communities in Ghana. Also, the study explored the effects of parent-child communication related to sexual and reproductive health in improving adolescent sexual reproductive health practices in Ghana. Data was collected from 300 adolescents in selected coastal communities within the Cape Coast Metropolis in Ghana. We found that many parents in the coastal communities within the Cape Coast Metropolis are unable to transmit SRH information to their children. The findings also revealed that level of formal education influenced parents’ ability to transmit SRH information to adolescents and exposes poor parent-adolescent relationship regarding SRH information in the communities studied. Aside from contributing to literature and informing policy directions on family communication patterns regarding adolescent SRH, the study brings more insight on how parents and their adolescents along coastal communities in Cape Coast, Ghana communicate SRH issues. Implications for counselling are outlined.

Organizing cross-sectoral housing provision planning: settings, problems and knowledge

ABSTRACT In the governance of housing provision, the public sector is considered unable efficiently to manage such problems through the traditional bureaucratic organizations and associated governing tools. Instead, municipalities are expected to engage in collaborative processes across sectors and with external stakeholders, with the overarching objective to deliver more efficient planning outcomes. As the processes are carried out across sectors, it opens up the opportunity to privilege certain sectors’ perspectives and marginalize others. By drawing from Mouffe's agonistic political theories, this article makes an empirical account of the political in organizing cross-sectoral collaborative planning in Swedish municipalities, with the empirical example of developing municipal programmes for housing provision. The article concludes that social service is severely marginalized in what is generally a depoliticized housing provision planning process. Underpinning the collaboration is the conceptualizing of housing provision as primarily a general deficit in constructing housing. Primarily organizing objectivist knowledge, housing provision is constructed as a technical and procedural matter rather than ideological and political. Through such organizing principles, the overarching housing provision problem remains undealt with, e.g. how do we provide housing to ‘all’ our citizens?
