description: This research evaluated the adsorption of celestine blue (CB) onto a novel Solanum tuberosum waste-magnetite nanocomposite (Mt@STB), prepared by an ecofriendly impregnation of magnetite (Mt) nanoparticles onto Solanum tuberosum waste (STB). The adsorbents characterization revealed that Mt@STB had a surface area (18.92 m2/g), pHpzc (7.55), porous morphology as well as suitable functional groups for efficient sequestration of CB onto the composite. The SEM, XRD, and EDX showed successful incorporation of 31.21 nm average size Mt nanoparticles on Mt@STB. Faster kinetics of CB sequestration from the wastewater was obtained for Mt@STB (100 min) compared to STB (140 min). Among four isotherm models, the Langmuir exhibited the best fit with R2 > 0.9971 and sum square errors (SSE) < 0.0151. The pristine STB and Mt@STB composite showed maximum monolayer CEB uptake of 7.61 and 9.02 mg/g, as well as optimum removal of 73.8 and 84.7%, respectively. The pseudo-second-order model was more suitable in the kinetic description, while thermodynamics revealed a physical, spontaneous, and endothermic CB uptake. Besides, the efficacy of the composite for CB was confirmed from efficient regeneration over three adsorption/desorption cycles, which specified the viability of Mt@STB as a sustainable material for the decontamination of CB polluted water. NOVELTY STATEMENT The adsorption of dyes from wastewaters has been widely studied due to the harmful effects on the ecosystem. However, research on the removal of celestine blue (CB) dye is rare despite its wide use in the nuclear and textile industries. Until date, there is no report on the adsorption of CB on biomaterial via biosorption. Therefore, the biosorption behavior of CB is presently unknown. Hence, this study reports the biosorption of CB onto a biosorbent (Solanum tuberosum peel [STB]) in an attempt to understand its biosorption behavior. Besides, the impregnation of magnetite (Mt) nanoparticles has been reported to enhance the uptake of most adsorbents for dye. To the best of our knowledge, such magnetic nanoparticle impregnation of STB has not been reported. We, therefore, synthesized a novel biowaste-magnetite composite (Mt@STB) and evaluated its potentials for the uptake as well as its reuse for CB biosorption.

description: We compute semi-analytic and numerical estimates for the largest Lyapunov exponent in a many-particle system with long-range interactions, extending previous results for the Hamiltonian Mean Field model with a cosine potential. Our results evidence a critical exponent associated to a power law decay of the largest Lyapunov exponent close to second-order phase-transitions, close to the same value as for the cosine Hamiltonian Mean Field model, suggesting the possible universality of this exponent. We also show that the exponent for first-order phase transitions has a different value from both theoretical and numerical estimates.

description: Phytomining of nickel (Ni) refers to cropping of selected Ni hyperaccumulator plants on Ni-rich serpentine soils. In this study, the effect of different fertilization regimes on the Ni yield of Odontarrhena chalcidica (syn. Alyssum murale) was evaluated within a field experiment on an Austrian serpentine site. Odontarrhena chalcidica was planted in six treatments: control, fertilized by mineral fertilizer, cow manure, pig manure, compost, and planted at higher plant density. A positive fertilization effect was observed: plants treated with NPK and pig manure produced significantly higher biomass (1.9 t ha−1 for both treatments). Nickel yields showed a clear trend for enhancement upon fertilization (cow manure: 22.7 kg Ni ha−1, pig manure: 21.3 kg Ni ha−1, NPK: 20.6 kg Ni ha−1), but were not significantly different from the control. As a result of Ni accumulation in plants, DTPA-extractable Ni pools were significantly lower after harvesting (average 37.3 mg kg Ni-DTPA−1) compared to the time of planting (average 45.6 mg kg Ni-DTPA−1) in organic fertilization treatments and plots of higher plant density. The application of organic fertilizers contributed also to improved soil quality. We conclude that fertilization can increase the phytomining potential of field-grown Ni hyperaccumulator plants in a soil-friendly manner.

 Material examined. Off Namibia, WALDA, Stn CY05, 21º46.3’S, 11º08.3’E, 2953 m, 11.06.1971: 12 males 23.0–27.0 mm, 1 ovig. female 30.2 mm, 3 females 31.9–41.7 mm.—Stn CY07, 22º53’S, 11º56’E, 2840 m, 17.06.1971: 1 ovig. female 34.8 mm.— Stn CY11, 17º30’S, 09º27’E, 4335, 30.06.1971: 1 female 20.0 mm.
 Remarks. Baba (2005) provided an excellent analysis of the material collected in different localities and identified as different species or subspecies. The specimens collected off Namibia agree quite well with the description and figures of the type material. Our material is also similar to M. subsquamosa aculeata Henderson, 1885 (between Marion Island and Crozet islands and off Chile, 2516–2654 m) and M. barnardi Kensley, 1968 (W of Cape Point, 2708–2965 m). As Baba (2005) pointed out both taxa are junior names of M. subsquamosa. The specimens collected in the Bay of Biscay and identified provisionally as M. subsquamosa by de Saint­Laurent (1985) correspond to M. exuta (see above). The species is characterized by the carapace having low scale­like ridges on the gastric region, the presence of a group of gastric spines, including 2 epigastric spines, the anterolateral spine of the carapace larger than antennal spine in size, directed anterolaterad, the rostrum spiniform, the abdominal segment 6 with posteromedian margin weakly convex, not produced, the eyestalks short relative to length, the mesial eye­spine present, the cornea relatively small, as broad as the eyespine, the first walking leg overreaching the end of the cheliped, the fixed finger of the cheliped without a denticulate carina on the distolateral margin, the dactyli of walking legs strongly curved distally, the ultimate flexor marginal tooth much closer to the penultimate than to tip of the article, and epipods present on the chelipeds.
 Distribution. Japan, eastern Australia, Chile, Marion Island, Crozet Islands, South Africa, between 2516 and 3960 m. The present material was collected off Namibia, between 2840 and 2953 m.

title: The development of infant-caregiver relationships in the common marmoset (Callithrix jacchus)
Creators: name: Locke-Haydon, Janet
Publisher: name: The Open University
Year: 1983

description: The thesis describes a study of infant social development carried out on captive common marmosets (Callithrix jacchus) over the first five months of life while maintained in family groups. From observations of nine infants from 2 to 22 weeks of age, a detailed quantitative account of the relationships between infants and their caregivers (other family members) has been produced. The amount of time infants spend in different activities with different caregivers varies with the age of the infant and with which caregiver is concerned as infants develop quantitatively and qualitatively different relationships with each type of caregiver. Independence of infants from caregivers is promoted primarily by the caregivers, infants appearing to seek more care than caregivers are prepared to give. Caregivers do not compensate for differences in each others' caregiving behaviour, nor do they compete for access to infants. From the results of these observations, the distribution of infants' time and activities among family members is suggested to result from the interaction of two factors: the tendency of an infant at a given age to seek a certain level of care, and the tendencies of family members to offer a certain level of care. This caregiving/care-seeking hypothesis generates several predictions which have been tested by experimentally manipulating the behaviour of particular caregivers using a neuroleptic drug to reduce care offered to and social interactions with infants. Observations of the experimental second group of eight infants have borne out several of the predictions from the hypothesis: Infants whose caregivers are drugged spend less time in non - care-seeking activities and there are some increases in care-seeking behaviour. Infants continue to seek care from caregivers in order of preference, and no compensation among caregivers is found. Results from the second group of infants provide support for the caregiving/care-seeking hypothesis but also indicate other factors which need to be taken into account.

description: The dichotomous-choice contingent valuation method is applied to measure consumers' value of quality-certificated organic beef. First, a logit model is estimated like previous studies. Second is a distribution-free approach. The Turnbull empirical distribution model is employed to solve negative willingness to pay and truncation problems. The result is shown that consumers are willing to pay 7,019∼10,607 Won/per 600g more than the current price of regular beef for quality- certificated organic beef.

description: We explore the connection between dust and star formation, in the context of environmental effects on galaxy evolution. In particular, we exploit the susceptibility of dust to external processes to assess the influence of dense environment on star-forming galaxies. We have selected cluster Abell 1758 from the Local Cluster Substructure Survey (LoCuSS). Its complex dynamical state is an ideal test-bench to track dust removal and destruction in galaxies due to merger and accretion shocks. We present a systematic panchromatic study (from 0.15 $\rm μ$m with GALEX to 500 $\rm μ$m with Herschel) of spectroscopically confirmed star-forming cluster galaxies at intermediate redshift. We observe that the main subclusters (A1758N and A1758S) belong to two separate large-scale structures, with no overlapping galaxy members. Star-forming cluster members are distributed preferentially outside cluster central regions, and are not grouped in substructures. Rather, these galaxies are being funneled towards the main subclusters along separate accretion filaments. Additionally, we present the first study of dust-to-stellar (DTS) mass ratio used as indicator for local environmental influence on galaxy evolution. Star-forming cluster members show lower mean values (32% at 2.4$\rm σ$) of DTS mass ratio and lower levels of infrared emission from birth clouds with respect to coeval star-forming field galaxies. This picture is consistent with the majority of star-forming cluster members infalling in isolation. Upon accretion, star-formation is observed to decrease and warm dust is destroyed due to heating from the intracluster medium radiation, ram-pressure stripping and merger shocks.

description: We have imaged the nearby galaxy merger Arp 299 at arcsecond and milliarcsecond resolution, using both the Very Large Array and the Very Long Baseline Array. The large-scale radio emission from the merger contains 5 bright, compact radio sources embedded in diffuse emission, with diameters less than 200 pc. Supernova rates of 0.1 to 1 per year are required to produce the VLA-detected radio emission in these sources. Two of the compact VLA radio sources, designated Source A and Source D, also have been detected and imaged at milliarcsecond scales. Source A, which is associated with the nucleus of one of the merging galaxies, contains five milliarcsecond-scale sources, each with a radio power between 100 and 1000 times that of the Galactic supernova remnant Cassiopeia A. Four of these have flat or inverted spectra and appear to be young supernovae. Three of the VLBI-scale sources are located within 10 pc (projected) of one another, and two are separated by less than 3 pc, indicating that they all may be within the same super starcluster or complex of such clusters. The brightest VLBI-scale source, A0, has an extremely inverted pectrum, with alpha larger than +2 at gigahertz frequencies. It seems to be the youngest supernova, which has not yet broken out of its circumstellar shell. The milliarcsecond radio sources within Source A appear to constitute a upernova factory, confirming the presence of an extreme starburst that peaked at least a few million years ago.

This analytical paper constructs five analytical questions and derives diverse ways to reach the answers fer each question. The present study also argues that the multi-level model provides a powerful tool for analysis of the data within which the number of observations varies.

description: Medicago sativa L. (alfalfa) are studied as potential phytoremediation agents of priority pollutants like polycyclic aromatic hydrocarbons (PAH). However, elucidation of the biochemical mechanisms involved in phytoremediation is a topic to be explored with knowledge gaps. This study aims to identify and classify proteins expressed in the aerial parts of laboratory-cultivated alfalfa in the presence and absence of pyrene, anthracene, and phenanthrene. Soil samples were amended with 100 mg.kg−1 of each PAH (total concentration of 300 ppm) and cultivated with alfalfa plants for 20 days. After this, aerial parts of cultivated plants from each condition were collected for qualitative proteomic analysis (ESI-Q/TOF). The results showed a significant increase (Student’s t-test p

It is necessary to establish an agricultural marketing body at the department level, and government bodies involved in agricultural trading should be privatized. Investment in marketing facilities should be increased, and agricultural cooperatives should play an important role in modernization of agricultural marketing. The wholesale markets in major cities should strengthen functions of wholesale selling.

description: This study reveals that the land tenure system was the main obstacle to general rural development in the pre-land reform Ethiopia. Although the 1975 land reform freed the peasantry from merciless exploitation by the landlord class, through a series of misguided polices, the military regime placed the peasants before an impassable barrier. The study shows also that the current government maintains the state ownership of land and pursues policies concerning the allocation, transfer and redistribution of land that are closely akin to those of the military regime. Furthermore, the results of study point to the fact that state ownership of land and the latent fear of future redistribution have created a sense of uncertainty, which in turn is translated in reluctance to invest in long-term land improvement measures.

description: We show that the dynamics between inherent structures in glass forming systems can be understood in purely dynamical terms, without any reference to ``topographic'' features of the potential energy landscape. This ``non-topographic'' interpretation is based instead on the existence of dynamical heterogeneities and on their statistical properties. Our view is supported by the study of simple dynamically facilitated models of glass formers. These models also allow for the formulation of quantitative theoretical predictions which are successfully compared to published data obtained in numerical and experimental studies of local dynamics of supercooled liquids.

description: To help understand our universe better, researchers and scientists currently run extreme-scale cosmology simulations on leadership supercomputers. However, such simulations can generate large amounts of scientific data, which often result in expensive costs in data associated with data movement and storage. Lossy compression techniques have become attractive because they significantly reduce data size and can maintain high data fidelity for post-analysis. In this paper, we propose to use GPU-based lossy compression for extreme-scale cosmological simulations. Our contributions are threefold: (1) we implement multiple GPU-based lossy compressors to our opensource compression benchmark and analysis framework named Foresight; (2) we use Foresight to comprehensively evaluate the practicality of using GPU-based lossy compression on two real-world extreme-scale cosmology simulations, namely HACC and Nyx, based on a series of assessment metrics; and (3) we develop a general optimization guideline on how to determine the best-fit configurations for different lossy compressors and cosmological simulations. Experiments show that GPU-based lossy compression can provide necessary accuracy on post-analysis for cosmological simulations and high compression ratio of 5~15x on the tested datasets, as well as much higher compression and decompression throughput than CPU-based compressors.

description: Delta-connected stator windings are often used in mass production of small Permanent Magnet Synchronous Machines (PMSMs). In comparison to star-connected stator windings, a delta-connected winding system offers advantages for manufacturing and lowers production costs. A main disadvantage of motors with such a winding system are additional losses caused by the Zero-Sequence Current Component (ZSCC). In this paper the ZSCC and its impact on the generated losses in a delta-connected PMSM used as a traction motor for a pedal electric cycle (Pedelec) is analysed. The calculated results are compared to those of a star-connected PMSM with the same design. We will show that the amplitude of the ZSCC depends on the operating point of the machine. As a result, the copper losses in the delta-connected machine are up to 5.8 % higher than the ones in the star-connected machine. On the other hand, the iron losses are 1 % smaller in the delta-connected machine. The efficiency of the delta-connected machine is still up to 4 % smaller.

description: Chile has many mine tailing deposits available for phytoremediation through the establishment of metal-tolerant plants. To guide such efforts, it is necessary to know whether roots exclude or take up metals, or if metals are mobilized to shoots. We evaluated a polyculture of ten native species 6 years after they were planted directly into tailings, amended with mycorrhiza before planting or planted with compost. All species were assessed for survival and hare damage. Growth, vigor, chlorophyll content index, and chlorophyll fluorescence were measured in seven species, and root and shoot concentrations of 11 metals and As were measured in five. All species had some level of stress, but there was no clear pattern related to foliar metal concentrations or amendments, the latter also having little effect on growth or survival. Copper, Fe, and Mo concentrations exceeded threshold toxicity levels for leaves and for animal feed in several species. Copper was most concentrated in the roots, and readily mobilized to leaves in three of the five species tested, but not in Prosopis chilensis (algarrobo) and Quillaja saponaria (quillay). Because of lower uptake overall, quillay is recommended for stabilizing tailings while also reducing transport to aerial tissues.

description: The formation of Population III (Pop III) stars is a critical step in the evolution of the early universe. To understand how these stars affected their metal-enriched descendants, the details of how, why and where Pop III formation takes place needs to be determined. One of the processes that is assumed to greatly affect the formation of Pop III stars is the presence of a Lyman-Werner (LW) radiation background, that destroys H$_2$, a necessary coolant in the creation of Pop III stars. Self-shielding can alleviate the effect the LW background has on the H$_2$ within haloes. In this work, we perform a cosmological simulation to study the birthplaces of Pop III stars, using the adaptive mesh refinement code Enzo. We investigate the distribution of host halo masses and its relationship to the LW background intensity. Compared to previous work, haloes form Pop III stars at much lower masses, up to a factor of a few, due to the inclusion of H$_2$ self-shielding. We see no relationship between the LW intensity and host halo mass. Most haloes form multiple Pop III stars, with a median number of four, up to a maximum of 16, at the instance of Pop III formation. Our results suggest that Pop III star formation may be less affected by LW radiation feedback than previously thought and that Pop III multiple systems are common.

description: The market share of U.S. wheat in Korea fell to 53% in 2002, primarily due to the weak competitiveness of U.S. wheat over Australian wheat in quality and price. In addition to upgrading the quality of wheat, maintaining consistent quality is also an important factor for market competitiveness. Australia and Canada offer consistent quality through various segregation systems based on quality specifications of wheat grains to satisfy the buyer's requirements. The Korean wheat flour milling industry would like to maintain the diversity of its import wheat markets. As consumer demand for better quality products grows, however, a higher and higher proportion of ASW wheat will be used for making noodles. Unless concerns over U.S. wheat quality are resolved in the near future, a decline in the market share of U.S. wheat in Korea seems to be inevitable.

description: We report on the analysis and prototype-characterization of a dual-electrode electro-optic modulator that can generate both amplitude and phase modulations with a selectable relative phase, termed a universally tunable modulator (UTM). All modulation states can be reached by tuning only the electrical inputs, facilitating real-time tuning, and the device is shown to have good suppression and stability properties. A mathematical analysis is presented, including the development of a geometric phase representation for modulation. The experimental characterization of the device shows that relative suppressions of 38 dB, 39 dB and 30 dB for phase, single-sideband and carrier-suppressed modulations, respectively, can be obtained, as well as showing the device is well-behaved when scanning continuously through the parameter space of modulations. Uses for the device are discussed, including the tuning of lock points in optical locking schemes, single sideband applications, modulation fast-switching applications, and applications requiring combined modulations.

description: The biotechnology has served as a basic knowledge on which several bio-related industries are based. The bio-related industries include ‘agricultural and fishery industry’, ‘bio-industry’, ‘food and beverage industry’, ‘chemical industry’, ‘health industry’, and ‘environmental industry’. Using firm-level micro data, this study carries out an empirical analysis to classify firms into above-mentioned six technology based bio-related industries. Korean Standard Industrial Classification System(KSICS) is commodity or output based industrial classification system which cannot be used in such studies that deal with technology-related issues. In order to investigate technology-related issues among industries we need to classify industries into knowledge or technology based category. In this study, industrial technological location of each firm is determined by applying LDM(Linear Discrimination Method) to IPC(International Patent Code) of Korean granted patent data of firms. The result shows that the industrial classification of firms based on output(KSICS) is quite different from that based on technology.
Statistical mechanical constitutive theory of polymer networks: The inextricable links between distribution, behavior, and ensemble

description: A fundamental theory is presented for the mechanical response of polymer networks undergoing large deformation which seamlessly integrates statistical mechanical principles with macroscopic thermodynamic constitutive theory. Our formulation permits the consideration of arbitrary polymer chain behaviors when interactions among chains may be neglected. This careful treatment highlights the naturally occurring correspondence between single-chain mechanical behavior and the equilibrium distribution of chains in the network, as well as the correspondences between different single-chain thermodynamic ensembles. We demonstrate these important distinctions with the extensible freely jointed chain model. This statistical mechanical theory is then extended to the continuum scale, where we utilize traditional macroscopic constitutive theory to ultimately retrieve the Cauchy stress in terms of the deformation and polymer network statistics. Once again using the extensible freely jointed chain model, we illustrate the importance of the naturally occurring statistical correspondences through their effects on the stress-stretch response of the network. We additionally show that these differences vanish when the number of links in the chain becomes sufficiently large enough, and discuss why certain methods perform better than others before this limit is reached.

description: Floating ferns of the genus Salvinia have great potential for phytoremediation of heavy metals. To date, the effect of essential metals on the accumulation and transport of toxic metals by aquatic ferns has not been suitably established. The aim of this study was to compare the ability of floating leaves of Salvinia minima and Salvinia rotundifolia species to accumulate Cr from Cr(VI solutions containing very low (0.02 mg L−1) and low (5 mg L−1) Zn concentrations. After 7-day metal-exposure period, results showed that Zn increased Cr accumulation in S. minima leaves whereas in S. rotundifolia decreased significantly. Contrarily Zn accumulation did not show great differences between species. This fact may indicate that Zn interfere Cr(VI) uptake by S. rotundifolia. Bioconcentration factor (BCF) and translocation factor (TF) were affected differently by Zn in both Salvinia species. Membrane stability index (MSI) of both Salvinia species was decreased significantly by 5 mg L−1 Zn concentration. Zn ions also increased hydrogen peroxide accumulation in fronds of Salvinia species. Total thiols (TT), non-protein thiols (NPT) and protein-bound thiols (PBT) were differentially affected by Cr(VI) and Zn ions. This study provides evidences on the involvement of different mechanisms against Cr(VI)/Zn toxicity in S. minima and S rotundifolia species.

description: A soil and plant survey was carried out in a tailing heap afforested 30 years ago to gain information about the changes in the tailing and metal uptake by plants. A poor development of Technosol was found. It was observed accumulation of OM spatio temporarily. Metal concentrations in the soil profile varied between plots. Extractable Pb concentrations ranged from 0.4 to 2.9%; extractable Cd varied 9.7–46% of the total concentration. PCA analysis shows DTPA-Zn and DTPA-Cu, Na, K, and OM have the widest concentrations range between soil layers. Casuarina equisetifolia and Pennisetum clandestinum formed a pristine uniform litter layer, whereas Eucalyptus camaldulensis did not form a litter layer. Casuarina equisetifolia has a higher population density (756 p ha−1) compared to Populus nigra (528 p ha−1) and E. camaldulensis (621 p ha−1). Pennisetum clandestinum grew successfully and covered the tailing, but Cd and Pb concentrations were above the domestic animal toxicity limits, 0.5 and 10 mg kg−1, respectively. Populus nigra absorbed more Zn than Casuarina equisetifolia and Eucalyptus camaldulensis. Trees species did not accumulate high foliar Cu and Zn concentrations, but Pb (47.7–124.3 mg kg−1) and Cd (5.7–26.8 mg kg−1) concentrations are over those reported for mature leaf tissues.

description: We derive the generalized partial wave expansion for $M \rightarrow N$ scattering amplitude in terms of spinor helicity variables. The basis amplitudes of the expansion with definite angular momentum $j$ consist of the Poincare Clebsch-Gordan coefficients, while $j$ constrains the UV physics that could generate the corresponding operators at tree level. Moreover, we obtain a series of selection rules that restrict the anomalous dimension matrix of effective operators and the way how effective operators contribute to some $2 \rightarrow N$ amplitudes at the loop level.

description: In accordance with the current of a recent economic history, that is, long-term economic change, this essay is a case study to analyze focused on concretely agricultural circumstances of Honam province that is the bread basket of the country. In the long run perspective view point, the latter half of 19C the Homan shore region comprised Naju-kun and Yungkwang-kun is an agriculture crisis, rural instability. As time goes from the first half year to the second year in 19C, the number of the region recorded a year of famine have increased. Most of them is a coastal plain land. The offices of the central government coped with the lean year in devastated district by tax exemption ; the fact of increasing scale of the tax exemption area verified the crisis of those areas. The situation of raising the scale of devastated districts by bad harvesting, especially it occurred to many times between 1876 a bad year and 1894 breaking out a peasants` uprising. The case study shows a surprising fact that the agriculture crisis in Chunra-Do(全羅道) grasped by the central government correspond with the harvesting register(秋收記) recorded by certain landlord in Yungkwang-kun.

subject: Potential Bilateral Trade

description: The objective of this study is to measure the impacts of agricultural product offer at the Third Round of Bangkok Agreement. Potential Bilateral Trade(PBT), which may be interpreted as a maximum level of trade diversion effect is estimated to US$ 1.6 billion for 122 agricultural products that requested by China. This amount exceeded current agricultural import from China. The biggest PBT is US$ 345 million for corn followed by US$ 250 million for food preparations and US$ 200 for tobacco. These results seem to back up the strategy of excluding agricultural product from concession at the Third Round of Bangkok Agreement. Or it supports Korean position of re-negotiating the inclusion of agricultural products after settlement of WTO/DDA negotiation.
