It's not easy being green: The evolution of galaxy colour in the EAGLE simulation

We examine the evolution of intrinsic u-r colours of galaxies in the EAGLE cosmological hydrodynamical simulations, which has been shown to reproduce the observed redshift z=0.1 colour-magnitude distribution well. The median u-r of star-forming ('blue cloud') galaxies reddens by 1 mag from z=2 to 0 at fixed stellar mass, as their specific star formation rates decrease with time. A red sequence starts to build-up around z=1, due to the quenching of low-mass satellite galaxies at the faint end, and due to the quenching of more massive central galaxies by their active galactic nuclei (AGN) at the bright end. This leaves a dearth of intermediate-mass red sequence galaxies at z=1, which is mostly filled in by z=0. We quantify the time-scales of colour transition due to satellite and AGN quenching, finding that most galaxies spend less than 2 Gyr in the 'green valley'. On examining the trajectories of galaxies in a colour-stellar mass diagram, we identify three characteristic tracks that galaxies follow (quiescently star-forming, quenching and rejuvenating galaxies) and quantify the fraction of galaxies that follow each track.
CUK-ZETA Multi-Input DC-DC Converter

This paper proposes a double input dc-dc converter based on integration of CUK and Zeta converter suitable for telecom power supplies. In the proposed converter, the input dc voltage can be either bucked or boosted and also input dc sources can deliver power to the load individually or simultaneously. The combination results in an output voltage of negative polarity, but by introducing a diode, capacitor cross-bridge, the polarity is reversed to positive voltage at the output terminals. The converter is capable of providing both the step-up and step-down conversion at reasonable duty ratios. The converter is analyzed for steady state behaviour and presented in this paper.
Teaching Atlas.ti™ in South Africa: Reflections on Doctoral Preparedness

Abstract Teaching qualitative data analysis using computer software such as Atlas.ti− to masters and doctoral students as well as university colleagues has presented a number of challenges together with moments of inspiration. The researcher has offered some brief reflective considerations, which have been conceptually located in postgraduate research and doctoral preparedness. Given the low number of PhD students who graduate in South Africa (SA), many scholars have inquired into the lack of progress of postgraduate research. Qualitative research, and in particular qualitative data analysis has not enjoyed structured support at universities, let alone computer assisted qualitative analysis support. Little is written in the qualitative data analysis literature about the impact and value of using Atlas.ti− in postgraduate work, particularly in the South African context. Therefore this reflective paper hopes to make some inroads into this field of study.
Maize chromosome additions and radiation hybrids in oat and their use in dissecting the maize genome

Plant recovery from wide-cross sexual hybridization between members of two subfamilies of grasses, as initially described in the production of haploid wheat plants in wheat ✕ maize crosses, can also be obtained in oat ✕ maize crosses. In wheat ✕ maize crosses, haploid wheat plants are obtained as a result of complete elimination of the maize chromosomes prior to embryo rescue. In contrast, about one-third of the plants from oat ✕ maize crosses contain one or more maize chromosomes in addition to a complete haploid complement of 21 oat chromosomes. Over the past few years, all ten maize chromosomes have been recovered as single chromosome additions to a haploid oat complement, and fertile disomic addition lines in oat have been obtained for maize chromosomes 1 through 9 as well as a ditelosomic from maize chromosome 10 short arm. Polymerase chain reaction (PCR) assays of DNA extracts for the maize-specific Grande-1 dispersed repeated element are used to detect plants with maize chromatin. Assays with maize chromosome-specific markers are used to identify which maize chromosome(s) is present, and genomic in situ hybridization analysis of root-tip cells is performed to visualize the number of maize chromosomes present. Plant phenotypes, transmission characteristics of addition chromosomes, and potential uses of the oat-maize addition lines are described here. We also emphasize the value of these strains for mapping duplicated maize sequences and gene families. Gamma irradiation of oat-maize addition lines is used to produce radiation hybrid lines with maize chromosomal segment deletions and translocations. Finally, we describe the use of radiation hybrids
Nebular and Stellar Dust Extinction Across the Disk of Emission-Line Galaxies on Small (KPC) Scales

We investigate resolved kpc-scale stellar and nebular dust distribution in eight star-forming galaxies at z~0.4 in the GOODS fields. Constructing the observed Spectral Energy Distributions (SEDs) per pixel, based on seven bands photometric data from HST/ACS and WFC3, we performed pixel-by-pixel SED fits to population synthesis models and estimated small-scale distribution of stellar dust extinction. We use Halpha / Hbeta nebular emission line ratios from Keck/DEIMOS high resolution spectra at each spatial resolution element to measure the amount of attenuation faced by ionized gas at different radii from the center of galaxies. We find a good agreement between the integrated and median of resolved color excess measurements in our galaxies. The ratio of integrated nebular to stellar dust extinction is always greater than unity, but does not show any trend with stellar mass or star formation rate. We find that inclination plays an important role in the variation of the nebular to stellar excess ratio. The stellar color excess profiles are found to have higher values at the center compared to outer parts of the disk. However, for lower mass galaxies, a similar trend is not found for the nebular color excess. We find that the nebular color excess increases with stellar mass surface density. This explains the absence of radial trend in the nebular color excess in lower mass galaxies which lack a large radial variation of stellar mass surface density. Using standard conversions of star formation rate surface density to gas mass surface density, and the relation between dust mass surface density and color excess, we find no significant variation in the dust to gas ratio in regions with high gas mass surface densities, over the scales probed in this study.
TRENDS IN LOGISTICS IN THE GERMAN E-COMMERCE AND THE PARTICULAR RELEVANCE OF MANAGING PRODUCT RETURNS

Background: There are several trends in logistics Internet ret ailers have to face nowadays, e.g. addressing and reaching customers through different sales channels (multi- or cross-channel management ), integration of new payment alternatives (combined online and/or mobile payment methods), ordering and delivery of pro ducts from an Internet retailer at the same day (same-day deliver y), and allowing product returns (management of pro duct returns). Here the question is, whether relevant factors influenci ng the buying behaviour of online shoppers as well as groups of these can be found. Methods: Our contribution is analysing this area in two way s. On the hand, an overview about these major trend s and the German e-commerce market will be given. On the other hand, the particular relevance of managing produc t returns will be discussed and through findings from an empirical investigation of German online shoppers expanded. Results: Four relevant factors influencing the behavior of online shoppers could be identified. Applying these four factors four different groups of online shoppers ca n be differentiated.
Security Vulnerabilities of Virtualization Technique

Cloud computing is a computing model for delivering resources in a convenient manner from a shared pool. The resources provisioned and released on an on-demand basis with minimal intervention of service provider. Cloud Computing is becoming the platform for all kind of web based services. Virtualization is the key concept to adopt the cloud computing. Virtualization offers many benefits comparing to real physical machine implementation infrastructure. Even though virtualization provides lots of benefits, it is also brings several security vulnerabilities. This paper presents the security breaches of various virtualization techniques that are applied in virtual machines, in which health care records maintained.
Reactions of Organic Monolayers on Carbon Surfaces Observed with Unenhanced Raman Spectroscopy

High sensitivity surface Raman spectroscopy was used to acquire spectra from monolayers of nitrophenyl groups covalently bonded to glassy carbon (GC) and ordered graphite. 4-Nitrophenyl radical was generated by electroreduction of 4-nitrophenyl diazonium ion in acetonitrile, then the radical covalently bonded to the carbon surface. Raman spectroscopy with a 488 nm laser and a CCD spectrograph revealed spectral features characteristic of the nitrophenyl group. Voltammetry, XPS, and Raman spectroscopic data established that the surface coverage was 6.5 x mol/cm2 on the basal plane of highly ordered pyrolytic graphite (HOPG). Electrochemical reduction of the nitrophenyl surface yielded significant spectral changes, perhaps due to formation of an amine. The similarity of the Raman results for modified HOPG and GC surface indicates that the nitrophenyl radical is quite aggressive, apparently attacking both edge plane and basal plane sites.
OPERATIONAL EXPERIENCE WITH THE LHC SOFTWARE INTERLOCK SYSTEM

The Software Interlock System (SIS) is a JAVA software project developed for the CERN accelerators complex. The core functionality of SIS is to provide a framework to program high level interlocks based on the surveillance of a large number of accelerator device parameters. The interlock results are exported to trigger beam dumps, inhibit beam transfers or abort the main magnets powering. Since its deployment in 2008, the LHC SIS has demonstrated that it is a reliable solution for complex interlocks involving multiple or distributed systems and when quick solutions for un-expected situations is needed. This paper is presenting the operational experience with software interlocking in the LHC machine, reporting on the overall performance and flexibility of the SIS, mentioning the risks when SW interlocks are used to patch missing functionality for personal safety or machine protection.
ZINC ADSORPTION BEHAVIOR OF DIFFERENT TEXTURED CALCAREOUS SOILS USING FREUNDLICH AND LANGMUIR MODELS

Zinc adsorption was studied in ten soils varying in texture or calcareousness of Punjab. Adsorption process was executed by equilibrating 2.5g soil in 25 ml of 0.01M CaCl2 solution containing 0, 5, 10, 15, 20, 25, 70, and 120 mg Zn L. Sorption data were fitted to Freundlich and Langmuir adsorption models. The data were best fitted in both linearized Freundlich and Langmuir equations as evidenced by higher correlation coefficient values ranging from 0.87 to 0.98. High clay contents ranging from 8 to 32 % and CaCO3 4.46 to 10.6 % promoted an increase in the amount of adsorbed Zinc in these soils. Adsorption of Zn increased with the increasing level of Zn and also increased with increase in clay, and CaCO3 contents. The maximum adsorption of Zn was observed in the Kotli whereas, the minimum in the Shahdra soil series.
THE RELATIONSHIP BETWEEN THINKING STYLES AND ACADEMIC ADJUSTMENT IN NURSING STUDENTS

Introduction: Adjustment together with its different aspects is considered a basic and extensive issue in psychology. Therefore, identifying the related factors, while developing knowledge of the field, can help reduce individual and interindividual problems. Hence, the aim of the present research is to investigate relationship between thinking styles and academic adjustment. Methods: This descriptivecorrelatinal study was conducted on 65 nursing students in Islamic Azad University (Khoy branch) selected through cluster sampling. To gather the data, two standard questionnaires on thinking styles of Strenberg,Wagner and Zang and academic adjustment questionnaire of Baker and Siryak were used. Data were analyzed using Pearson correlation test and multiple regression. Results: The results of Pearson correlation test showed that there were positive, significant relations between judiciary, executive, hierarchical, liberal, external and type I thinking styles with academic adjustment, while thinking style of anarchism showed a negative and significant relationship. The results of multiple regression indicated that type I thinking styles positively and type III thinking styles negatively predict academic adjustment. In general, 20.4% of variance for academic adjustment is explicable based on the preferred thinking styles. Also the academic adjustment of nursing students was above the average. Conclusion: There was a relationship between academic adjustment and the kind of thinking style. Also, one could predict nursing students’ academic adjustment by knowing their scores of type I and Type III thinking styles. Therefore, improvement and promotion of the academic adjustment of nursing students demands paying more attention to their type of thinking style.
Endophytic fungi from calamus kerrianus and Wallichia caryotoides (Arecaceae) at Doi Suthep-Pui National Park, Thailand

Fungal endophytes associated with the palms, Calamus kerrianus (rattan) and Wallichia caryotoides (taorang) were investigated at two sites within Doi Suthep-Pui National Park, Thailand. Endophytic fungi were isolated from different tissue types (petiole, leaf, lamina and leaf veins) during three periods of the year, rainy season (July-October, 1999), cold season (November 1999-February 2000) and hot season (March-June 2000). Thirty-five endophytic fungi isolated included xylariaceous taxa (20 morphotypes), sterile mycelia, one unidentified and 13 mitosporic fungi including Cladosporium sp. , Colletotrichum gloeosporioides, Corynespora-like sp. , Fusarium sp. , Guignardia cocaicola, Paecilomyces sp. Pestalotiopsis sp. , Phialophora sp. , Phoma sp. , Phoma-like sp. , Phomopsis sp. , Phyllosticta sp. , and Sarcopodium sp. The endophyte species, their relative frequency, isolate prevalence and diversity did not differ significantly between host species, tissue types, study sites and seasons.
Multi-Metric Based Face Identification with Multi Configuration LBP Descriptor

This paper deals with the performance improvement of a mono modal face identification. A statistical study of various structures of the LBPs (Local Binary Patterns) features associated to two metrics is performed to find out those committing errors on different subjects. Then, during the identification stage, these optimal variants are used, and a simple score level fusion is adopted. The score fusion is done after min-max normalization. The main contribution of this paper consists in the association of multiple LBP schemes with different metrics using simple fusion operation. The overall identification rating up to 99% using AT&T database is achieved.
Effect of task factors on the heart rate recovery time in a lifting task

BACKGROUND: There is an extensive body of research reviewing the effect of task factors on the Maximum Acceptable Weight of Lift (MAWL) or heart beats elevation as a result of a manual material handling task. However, there are now studies that investigate the effect of task factors on the heart rate recovery time (HRR). OBJECTIVE: The purpose of the study was twofold: (1) to determine the HRR for a series of lifting tasks based on the activity heart rate and by using a set of task variables, (2) to compare the effect of three task factors on the HRR following a lifting task. METHODS: This research was constituted of capturing the duration that heart rate needs to get to a steady state following a lifting task, along with conducting the survey of perceived exertion (Borg). Three independent variables of this study (taskfactors) were weight of the lift (10 and 20 kg), frequency of the lift (6 and 9 lifts per minute), and the duration of the lift (5 and 10 minutes). Given the possible treatment combinations, a total of 8 treatments was obtained. Twenty-four university male students performed the lifting tasks in a between-subject design. Each participant performed one treatment by lifting a box from knuckle to shoulder height at a certain frequency, duration and weight. All eight treatments were equally replicated with three observations per treatment group. RESULTS: Increasing weight and frequency of the lift significantly increased the HRR (respectively by 37% and 34%), while the HRR had a slight decrease when duration was doubled (approximately −2.7%). Weight of the lift was the only factor led to a significant change in the perceived difficulty of the task among participants (approximately 20%). CONCLUSIONS: Among main factors, frequency and weight of the lift had a significant effect on the HRR (p-values < 0.1). Among the interaction effects, the interaction of frequency and duration had a significant effect on the HRR. The only factor that had a significant effect on the Borg-rating was weight of the lift (p-value < 0.1).
Benchmarks in Aggregate Household Portfolios

Reference–dependent preference models assume that agents derive utility from deviations of consumption from benchmark levels, rather than from consumption levels. These references can be either backward-looking (as explicit in the Habit literature) or forward-looking (as implicitly suggested by Prospect Theory). For both cases, we specify and estimate a fully structural multi-variate Brownian system in optimal consumption, portfolio and wealth using aggregate household financial and real estate wealth data. Our results reveal that references are (i) strongly relevant, (ii) state-dependent, and (iii) that the data is more consistent with the backwardthan the forward-looking reference model.
Low-threshold blue lasing from silk fibroin thin films

Silk is a natural biocompatible material that can be integrated in a variety of photonic systems and optoelectronic devices. The silk replication of patterned substrates with features down to tens of nanometers is exploited to realize highly transparent, mechanically stable, and free-standing structures with optical wavelength size. We demonstrate organic lasing from a blue-emitting stilbene-doped silk film spin-coated onto a one-dimensional distributed feedback grating (DFB). The lasing threshold is lower than that of organic DFB lasers based on the same active dye. These findings pave the way to the development of an optically active biocompatible technological platform based on silk.
Cloning and Expression of Fusion (F) and Haemagglutinin-neuraminidase (HN) Epitopes in Hairy Roots of Tobacco (Nicotiana tabaccum) as a Step Toward Developing a Candidate Recombinant Vaccine Against Newcastle Disease

Newcastle is a significant avian disease continuing to cause considerable loss. Developments in genetic engineering have led to plant-based platforms for human and animal vaccine production. Recombinant vaccine production in hairy root systems have several advantages over stable expression in whole plants, including high growth rates, ready genetic manipulations, high levels of recombinant protein production, and the potential for bioreactor culture. In an attempt to develop a recombinant vaccine in hairy roots, the sequences encoding fusion (F) and haemagglutinin-neuraminidase (HN) epitopes of Newcastle disease virus were cloned in pBI121 expression vector which was then transferred into leaf disks of tobacco (Nicotiana tabaccum) 'Turkish' cultivar by means of Agrobacterium rhizogenes. Hairy roots developed on MS medium containing 50 mg/L kanamycin and 30 mg/L meropenem. Incorporation of the heterologous gene in the genome of hairy roots was confirmed by PCR. Expression analyses were performed by real-time PCR at transcription level and by dot-blot and ELISA assays at translation level, all confirming the expression of the heterologous gene and production of the recombinant protein.
Effect of growing beef replacement heifers on wheat pasture before and during breeding on reproductive performance

ABSTRACT Reproductive performance of heifers grazing wheat pasture before and during breeding was compared with heifers grazing wheat pasture until approximately 3 wk before breeding. In each of 2 yr, 40 Angus and crossbred heifers were placed on wheat pasture in December and assigned to treatment groups in mid March. Group 1 (WP; n = 20) remained on wheat pasture through estrus synchronization and fixed-time AI (FAI). Group 2 (DL; n = 20) was placed in drylot and fed a corn-based growing ration (11.1% CP) through estrus synchronization and FAI. Heifers were exposed to bulls 10 d after FAI for 45 d. Conception after FAI was determined at 32 d post-AI by ultrasonography. Weekly blood samples starting 5 wk before FAI were obtained to describe luteal activity before estrus synchronization and for analysis of urea nitrogen concentrations before and during estrus synchronization and FAI. Percentage of heifers with luteal activity was 75 and 55% for WP and DL, respectively. The DL heifers were heavier than WP heifers (408 vs. 394 kg ± 4.49) at AI but were similar in final weight on native range (417 vs. 414 kg ± 5.26). Conception rate to FAI (53 vs. 43%) and final pregnancy rate (95 vs. 88%) were similar for WP and DL. Concentrations of urea were less (5.77 vs. 29.15 mg/dL) for DL heifers during all weeks after treatments were imposed. Reproductive performance of heifers grazing wheat pasture during estrus synchronization and FAI was similar to that of drylot heifers consuming a corn-based growing diet.
Cost-effective monitoring of organic enrichment resulting from salmon mariculture

Two methods of environmental monitoring proposed for the salmon mariculture industry are compared and contrasted on the basis of scientific and cost-effectiveness criteria: a technique based on macrofaunal community structure and one using process-oriented sediment geochemistry. For this purpose, field sampling was confined to one salmon farm and a nearby reference site in the Bay of Fundy. Both methods produced significant differences between farm and reference sites, as well as meeting other appropriate scientific criteria. The geochemical method was based on field measurements of sedimentary Eh, by redox electrode, and sedimentary sulphide after fixing the sediment in a sulphur anti-oxidant buffer and ion analyses with Ag/Ag sulphide and combination reference electrode. Both measures can be completed in the field from the sampling vessel. Results suggested that the geochemical method was of significantly lower cost than the technique based on macrofaunal community structure. This is because of the lengthy laboratory time required to determine the identity and abundance of macrofaunal taxa. Both methods can categorize the sedimentary organic impact as normal, oxic, hypoxic, or anoxic, which depends ultimately on the dominant microflora present. This, in turn, depends on the rate of carbon reaching the sediment, as well as its utilization by biological and physical processes.
