In vitro enzymatic chlorophyll catabolism in wheat elicited by cereal aphid feeding

Chlorophyll degradation is a complex phenomenon that often accompanies insect feeding damage to plants. Loss of chlorophyll can be initiated by several reactions, including oxidative bleaching, chlorophyllase activity, and Mg‐dechelatase activity. Extracts from the Russian wheat aphid [Diuraphis noxia (Mordvilko)], the bird cherry‐oat aphid [Rhopalosiphum padi (L.)], and aphid‐infested and uninfested wheat plants were assayed in vitro for activities involved in chlorophyll degradation. Although the initial infestation was the same (10 apterous adults) for both aphid species, D. noxia weight was significantly higher than R. padi after feeding for 12 days. Consequently, D. noxia feeding caused greater fresh leaf weight reduction than R. padi feeding. Chlorophyll degradation assays showed no activity from either D. noxia or R. padi extracts. Plant extract assays showed a significant difference in Mg‐dechelatase activity, while no difference was detected in either the chlorophyllase or oxidative bleaching pathways among the aphid‐infested or uninfested plant extracts. Diuraphis noxia‐infested leaf extracts showed a greater increase of Mg‐dechelatase activity than either R. padi‐infested or the uninfested plants. The findings suggest that leaf chlorosis elicited by D. noxia feeding is different from the chlorophyll degradation that occurs in natural plant senescence. Aphid‐elicited chlorosis might be the result of a Mg‐dechelatase‐driven catabolism of chlorophyll in challenged wheat seedlings, however, the factor(s) from D. noxia that elicited the increase of Mg‐dechelatase activity still remain to be determined.

Ileal Digestibility of Amino Acids in Fish Meal-Based Diets for Broiler Starters Using Regression Technique

An experiment was conducted to determine apparent ileal digestibility of crude protein (CP) and amino acids (AA) and digestible CP and AA of fish meal (FM) in 21-d-old broiler chickens using the regression technique. Four diets containing 0, 1, 2, and 3% FM in place of cornstarch were formulated with FM as the sole contributor of CP and AAs in the sequential diets. Eighty 14-d-old broiler chicks were weighed, and sorted by body weight and randomly allotted to the experimental diets with 4 replicates per diet and 5 chicks per replicate. Titanium dioxide was added to the diets at the rate of 5 g/kg diet as an indigestible marker. They were fed the experimental diets till d 21 post hatch when they were killed by asphyxiated with CO 2 and digesta from the last two-third of ileum collected. The concentrations of CP and AA in the diets increased as dietary FM increased. Apparent digestibility of CP and AA significantly (P<0.05) increased with dietary FM inclusion but with a decrease in the 3% FM diet. The digestibility values of CP, lysine and methionine estimated as slopes of the regression of the amount of CP or AA digested dry matter intake dry matter intake (DMI) at the terminal ileum against CP or AA intake dry matter intake (DMI) were 88.7, 97.2 and 97.0% respectively. The digestible amounts of CP, lysine and methionine of FM were 63.63 g, 5361.04 mg and 1801.45 mg. Results of the study suggest a maximum level of 2% inclusion of FM was adequate for broiler starter chicks as higher levels may induce higher endogenous CP and AA flow and hence reduced digestibility of these nutrients.
Title The ITCZ in the Central and Eastern Pacific on Synoptic Time Scales Permalink

The ITCZ in the central and eastern Pacific on synoptic time scales is highly dynamic. The active season extends roughly from May through October. During the active season, the ITCZ continuously breaks down and re-forms, and produces a series of tropical disturbances. The life span of the ITCZ varies from several days to 3 weeks. Sixty-five cases of ITCZ breakdown have been visually identified over five active seasons (1999–2003) in three independent datasets. ITCZ breakdown can be triggered by two mechanisms: 1) interaction with westward-propagating disturbances (WPDs) and 2) the vortex rollup (VR) mechanism. Results show that the frequency of occurrence of ITCZ breakdown from these two mechanisms is the same. The VR mechanism may have been neglected because the produced disturbances are rather weak and they may dissipate quickly. The ITCZ shows a strong tendency to re-form within 1–2 days in the same location. The ITCZ may break down via the VR mechanism without any other support, and thus it may continuously generate numerous tropical disturbances throughout the season. There are two main differences between the two mechanisms: 1) The WPDs-induced ITCZ breakdown tends to create one or two vortices that may be of tropical depression strength. The VR-induced ITCZ breakdown generates several nearly equal-sized weak disturbances. 2) The WPDs tend to disturb the ITCZ in the eastern Pacific only. Disturbances generally move along the Mexican coast after shedding off from the ITCZ and do not further disturb the ITCZ in the central Pacific. Therefore, the VR mechanism is observed more clearly and is the dominating mechanism for ITCZ breakdown in the central Pacific.
The formation of NGC 3603 young starburst cluster: "prompt" hierarchical assembly or monolithic starburst?

The formation of very young massive clusters or "starburst" clusters is currently one of the most widely debated topic in astronomy. The classical notion dictates that a star cluster is formed in-situ in a dense molecular gas clump followed by a substantial residual gas expulsion. On the other hand, based on the observed morphologies of many young stellar associations, a hierarchical formation scenario is alternatively suggested. A very young (age $\approx$ 1 Myr), massive ($>10^4M_\odot$) star cluster like the Galactic NGC 3603 young cluster (HD 97950) is an appropriate testbed for distinguishing between such "monolithic" and "hierarchical" formation scenarios. A recent study by Banerjee and Kroupa (2014) demonstrates that the monolithic scenario remarkably reproduces the HD 97950 cluster. In the present work, we explore the possibility of the formation of the above cluster via hierarchical assembly of subclusters. These subclusters are initially distributed over a wide range of spatial volumes and have various modes of sub-clustering. Unlike the monolithic model that reproduces HD 97950 very well, the same is found to be prohibitive with hierarchical assembly alone. Only those systems which assemble promptly into a single cluster (in $\lesssim1$ Myr) from a close separation (all within $\lesssim2$ pc) could match the observed density profile of HD 97950 after $\approx70$% gas dispersal. These results therefore suggest that NGC 3603 young cluster has formed essentially monolithically, i.e., either in-situ or via a prompt assembly, followed by a substantial residual gas expulsion. Both scenarios are consistent with the inferred young age and the small age spread of this cluster. Future observations of molecular cloud filaments with ALMA and proper motion measurements of young clusters with Gaia will provide more direct tests of such birth environments. [Abridged]
Using woody genera for phytogeographic regionalization at a medium scale: A case study of Italy

We present a phytogeographic regionalization based on native woody flora, identifying the most useful taxonomic level, geographic variables, and orographic pattern, selecting Italy as a case study. We generated seven distance matrices among the 20 administrative regions, and using Pearson’s correlation coefficients and PCA, we verified whether distances between regions were invariant across the different sampling strategies. Once this invariance was established, we focused on genera representation. We defined two orographic indices and performed Kruskal–Wish multidimensional scaling and K-means clustering to assess Italy’s phytogeographic regionalization. A major north–south and a minor east–west gradient described the relationships between regions. Floristic diversity was strongly correlated with the region’s orography, with hills being the most important orographic feature that increased plant diversity; the effect of the orographic patterns was independent from the geographic clines observed. Despite t.
Integrating ICT into Rural South African Schools: Possible Solutions for Challenges

Abstract The influence of ICT in schools cannot be overemphasized as its utility is changing the way students learn, teachers teach, and support staff work. ICT adoption in South African schools has therefore gained momentum. Whilst ICT is fully integrated into many if not all schools in urban areas in South Africa, regrettably the same cannot be said about rural schools. This has created a ‘digital divide’ between rural and urban schools. Theoretically, this paper is informed by social justice theory. Methodologically, the extant literature relied upon to make the case for ICT in South Africa’s rural schools. The same approach is used to identify key challenges militating against smooth introduction of ICT into South African schools. Thereafter, suggestions for overcoming identified challenges are provided. The aim is to help bridge the apparent digital divide between rural and urban schools in South Africa.
High-energy neutrinos from FR0 radio galaxies?

The sources responsible for the emission of high-energy ($\gtrsim$ 100 TeV) neutrinos detected by IceCube are still unknown. Among the possible candidates, active galactic nuclei with relativistic jets are often examined, since the outflowing plasma seems to offer the ideal environment to accelerate the required parent high-energy cosmic rays. The non-detection of single point sources or -- almost equivalently -- the absence, in the IceCube events, of multiplets originating from the same sky position, constrains the cosmic density and the neutrino output of these sources, pointing to a numerous population of faint sources. Here we explore the possibility that FR0 radiogalaxies, the population of compact sources recently identified in large radio and optical surveys and representing the bulk of radio-loud AGN population, can represent suitable candidates for neutrino emission. Modeling the spectral energy distribution of a FR0 radiogalaxy recently associated to a $\gamma$-ray source detected by the Large Area Telescope onboard Fermi, we derive the physical parameters of its jet, in particular the power carried by it. We consider the possible mechanisms of neutrino production, concluding that $p\gamma$ reactions in the jet between protons and ambient radiation is too inefficient to sustain the required output. We propose an alternative scenario, in which protons, accelerated in the jet, escape from it and diffuse in the host galaxy, producing neutrinos as a result of $pp$ scattering with the interstellar gas, in strict analogy with the processes taking place in star-forming galaxies.

Translation and Adaptation of Revised Children's Anxiety and Depression Scale

The aim of the present study was to translate, adapt and validate the English version of Revised Children’s Anxiety and Depression Scale (RCADS) into Urdu language to make it more comprehensible and reliable for Pakistani population. This study was based on three stages; (1) Translation and Adaptation of Revised Children’s Anxiety and Depression Scale, (2) Finding out linguistic Equivalence/Cross validation, and (3) establishing psychometric properties of Revised Children’s Anxiety and Depression Scale. In first phase; Revised Children’s Anxiety and Depression Scale was translated into Urdu language. Standard procedure of translation was followed. In order to find out the difficulty in language and ambiguity or other issues, a pilot study was conducted. Second phase of the study was characterized to find out the linguistic equivalence of Revised Children’s Anxiety and Depression Scale. A Sample of 217 participants, 102 male and 115 females was selected for the administration of scale, ranging from age 12 to 18 years. Random and purposive sampling procedures were used to select the participants. In third phase psychometric properties of Urdu version of RCADS was established. In order to find out the linguistic equivalence between original and translated versions of RCADS, and to establish the psychometric properties of RCADS, Pearson Product moment coefficient of correlation and cronbach’s alpha were used. The estimate shows significant results (r=.87) at . 01 level of significance. The scale demonstrated its strength by providing significant testretest reliability (r=.83) at . 01 alpha level.
Climatology of Tropical Cyclogenesis in the North Atlantic (1948–2004)

The threat posed to North America by Atlantic Ocean tropical cyclones (TCs) was highlighted by a series of intense landfalling storms that occurred during the record-setting 2005 hurricane season. However, the ability to understand—and therefore the ability to predict—tropical cyclogenesis remains limited, despite recent field studies and numerical experiments that have led to the development of conceptual models describing pathways for tropical vortex initiation. This study addresses the issue of TC spinup by developing a dynamically based classification scheme built on a diagnosis of North Atlantic hurricanes between 1948 and 2004. A pair of metrics is presented that describes TC development from the perspective of external forcings in the local environment. These discriminants are indicative of quasigeostrophic forcing for ascent and lower-level baroclinicity and are computed for the 36 h leading up to TC initiation. A latent trajectory model is used to classify the evolution of the metrics for 496 storms, and a physical synthesis of the results yields six identifiable categories of tropical cyclogenesis events. The nonbaroclinic category accounts for 40% of Atlantic TCs, while events displaying perturbations from this archetype make up the remaining 60% of storms. A geographical clustering of the groups suggests that the classification scheme is identifying fundamentally different categories of tropical cyclogenesis. Moreover, significant differences between the postinitiation attributes of the classes indicate that the evolution of TCs may be sensitive to the pathway taken during development.
The determinants of scientific research agenda: Why do academic inventors choose to perform patentable versus non-patentable research?

This paper explores the determinants of scientific research agenda. By using an original dataset that includes extensive information about 269 French academic inventors, we analyze why scientists choose to perform patentable versus non-patentable research. Usually economic studies tackle this problem by using the number of invented patents as a proxy of researchers’ willingness to perform patentable research. The originality of the paper is that, in addition to the number of invented patents, we rely on a survey-base dependant variable that indicates whether or not scientists acknowledge orienting deliberately their research towards patentable areas. Our results indicate that past experience with respect to patenting activity matters: academic inventors who have already experienced a successful technology transfer are more inclined to orient their research towards patentable domains. Similarly, the institutional environment plays an explanatory role, whereas conversely, scientific discipline, age and individual research performance do not seem to affect the decision to orient research towards patentable areas. Yet, age and scientific performance positively influence the number of patents scholars effectively invent.
Requiem for an ideal clock

The 'problem of time' remains an unresolved issue in all known physical descriptions of the Universe. One aspect of this problem is the conspicuous absence of time in the Wheeler-Dewitt equation, which is the analogue of the Schrodinger equation for the Universal wavefunction. Page and Wootters famously addressed this problem by providing a mechanism for effectively introducing time evolution. Their method, which is sometimes called the conditional probability interpretation (CPI), requires the identification of an internal clock system that is meant to keep time for the remainder of the Universe. Most investigations into this idea employ the idealized limit of a non-interacting clock system, the so-called ideal clock. However, by allowing for interactions, we have found the counter-intuitive result that a non-interacting clock is not necessarily the optimal choice, even if it is 'ideal'. In particular, the uncertainty that is associated with the physical measurement of an atomic clock is found to decrease monotonically as the interactions grow stronger. This observation, which is reinforced by a previous study using a semi-classical clock, paves the way to an independent argument that is based on the energy conservation of any isolated system. Our conclusion is that ideal clocks must be prohibited from the CPI, as interactions are necessary for describing time evolution as a strict matter of principle.
A panel error correction approach to explore spatial correlation patterns of the dominant housing market in Australian capital cities

Purpose - – A panel error correction model has been developed to investigate the spatial correlation patterns among house prices. This paper aims to identify a dominant housing market in the ripple down process. Design/methodology/approach - – Seemingly unrelated regression estimators are adapted to deal with the contemporary correlations and heterogeneity across cities. Impulse response functions are subsequently implemented to simulate the spatial correlation patterns. The newly developed approach is then applied to the Australian capital city house price indices. Findings - – The results suggest that Melbourne should be recognised as the dominant housing market. Four levels were classified within the Australian house price interconnections, namely: Melbourne; Adelaide, Canberra, Perth and Sydney; Brisbane and Hobart; and Darwin. Originality/value - – This research develops a panel regression framework in addressing the spatial correlation patterns of house prices across cities. The ripple-down process of house price dynamics across cities was explored by capturing both the contemporary correlations and heterogeneity, and by identifying the dominant housing market.
Isoflavone supplementation reduces low-density lipoprotein cholesterol levels in postmenopausal women

METHODS A double-blind randomized placebo-controlled trial was conducted from January 2010 until February 2011. In total 180 postmenopausal women were randomized into an isoflavone group and a control group of 90 subjects each. The isoflavone group received tablets containing 100 mg soy isoflavones and 500 mg calcium carbonate, while the control group received 500 mg calcium carbonate only. Supplementation was given once daily for 1 year. Plasma lipid levels [triacylglycerol, total, low-density lipoprotein (LDL), and high-density lipoprotein (HDL) cholesterols] were assessed at baseline, and after 6 and 12 months of supplementation using an enzymatic colorimetric method (Cobas c 111, Roche). Independent t-test was used for data analysis.
Discovery of Scattering Polarization in the Hydrogen Lyα Line of the Solar Disk Radiation

There is a thin transition region (TR) in the solar atmosphere where the temperature rises from 10,000 K in the chromosphere to millions of degrees in the corona. Little is known about the mechanisms that dominate this enigmatic region other than the magnetic field plays a key role. The magnetism of the TR can only be detected by polarimetric measurements of a few ultraviolet (UV) spectral lines, the Lyα line of neutral hydrogen at 121.6 nm (the strongest line of the solar UV spectrum) being of particular interest given its sensitivity to the Hanle effect (the magnetic-field-induced modification of the scattering line polarization). We report the discovery of linear polarization produced by scattering processes in the Lyα line, obtained with the Chromospheric Lyman-Alpha Spectro-Polarimeter (CLASP) rocket experiment. The Stokes profiles observed by CLASP in quiet regions of the solar disk show that the Q/I and U/I linear polarization signals are of the order of 0.1% in the line core and up to a few percent in the nearby wings, and that both have conspicuous spatial variations with scales of ∼10 arcsec. These observations help constrain theoretical models of the chromosphere–corona TR and extrapolations of the magnetic field from photospheric magnetograms. In fact, the observed spatial variation from disk to limb of polarization at the line core and wings already challenge the predictions from three-dimensional magnetohydrodynamical models of the upper solar chromosphere.
