Recent P-wave seismic tomography11 revealed four geometries of subducted slabs in the mantle. Type I refers to a slab that is stagnant above the 660-km discontinuity. Type II is assigned to slabs that penetrate the 660-km discontinuity (for example, Kuril). Type III slabs lie in the uppermost lower mantle at depths between 660–1,000 km (for example, Tonga–Kermadec, Sumatra and South America). Type IV slabs continuously descend into the mid lower mantle. Seismic tomography11, 12, 13 provides morphological images of the subducted slabs in Earth’s mantle, but does not give any insight into the dynamic features of the slab. However, the seismic anisotropy observed in the mantle provides information on the flow direction of the slabs in the deep mantle because this anisotropy may be the reflection of the CPO of the constituent minerals, which is yielded by dislocation creep deformation. As shown in previous reports, an important anisotropy that demonstrates clear shear-wave splitting was observed in the uppermost lower mantle of the Tonga–Kermadec slab region1, 2. Recently, such anisotropies were also observed in the uppermost lower mantle of other slab regions3, 4, 5. In these observations, shear wave splitting shows fast polarization that is generally parallel to the plane of the subducted plate (for example, Tonga–Kermadec, Java, Peru and Kurile)1, 2, 3, 4, whereas other observed slab regions do not show a consistent splitting pattern3. It is therefore interesting to examine how the observed shear-wave anisotropy could be interpreted by the CPO of the lower-mantle minerals. It is generally accepted that in the pyrolitic mantle model, the constituents of the lower mantle are bridgmanite or (Mg,Fe)SiO perovskite, of space group Pbnm (77 vol%), ferropericlase (16 vol%) and CaSiO perovskite (7 vol%)14. The contribution of the CPO of ferropericlase to seismic anisotropy is negligible because of its nearly isotropic elasticity at the uppermost lower mantle conditions15. CaSiO perovskite is elastically anisotropic16 but the contribution of this phase to seismic anisotropy will not be substantial because of the small amount of CaSiO in the lower mantle. In contrast, it is anticipated that considerable seismic anisotropy can be produced by the CPO of bridgmanite17, 18 on the basis of its high elastic anisotropy19, 20 and overwhelming presence in the lower mantle. We therefore focused on the deformation-induced CPO of bridgmanite as the most important factor in lower-mantle seismic anisotropy. We performed shear deformation experiments on bridgmanite with a controlled strain rate under lower-mantle conditions by employing the deformation-DIA-type multi-anvil press with the Kawai-type cell assembly (6–8 type)10. Dense, sintered (Mg Fe )SiO bridgmanite aggregates synthesized at 25 GPa and 1,873 K were used as samples for the deformation experiments. A backscattered electron image (Fig. 1a) and pole figures (Fig. 2a) of sintered bridgmanite revealed that the sample was an equigranular aggregate with a typical grain size of 15 μm and a random crystallographic orientation, determined from two-dimensional monochromatic X-ray diffraction patterns (see Methods). In the deformation experiments, a thin ellipse of the bridgmanite aggregate with a strain marker of Ni foil (which was initially set at the middle of the sample, perpendicular to the cut surfaces of the pistons) was sandwiched between 45°-cut polycrystalline dense alumina pistons at the centre of the cell assembly. As the differential rams of the deformation-DIA press advance, the alumina pistons apply simple shear to the thin bridgmanite sample. Figure 1b and c shows the microstructures of the recovered samples from the undeformed (annealing only) experiment (run K116) and from the deformation experiment (run K122), respectively, both performed at identical pressure (P) and temperature (T) conditions (25 GPa, 1,873 K). In the former, the strain marker was almost normal to the cut surfaces of the alumina pistons, showing that the shear strain of the bridgmanite sample was very close to zero. The sample was thus almost free from deformation throughout the experimental processes; that is, compression, heating, annealing and subsequent decompression. As shown in Fig. 1c, the strain marker definitely tilted in the deformed sample. From the tilting angle of the strain marker (~38°) and the deformation time (1 h), the total strain and average strain rate were determined to be γ ≈ 0.8 and , respectively. The thickness of the deformed sample was reduced by about 20% in comparison with the original, suggesting that a uniaxial component of deformation was present. The microstructural observation in Fig. 1d show that elongated bridgmanite grains of sizes up to 30–40 μm accumulated in the shear direction and are surrounded by small grains of less than a few micrometres. The structural features indicate that dynamic recrystallization occurred. The CPO of bridgmanite could therefore be induced by deformation involving dislocations. The crystallographic orientation of the bridgmanite was determined using the two-dimensional monochromatic X-ray diffraction pattern method7, 9, 21 for both the starting and deformed samples. The sheared bridgmanite aggregate demonstrated strong fabric (Fig. 2b), whereas the starting material did not show a notable CPO pattern (Fig. 2a). In the sheared bridgmanite, the [100] axis was oriented perpendicular to the shear plane. Although weak girdle patterns of the [001] and [010] axes (which correspond to uniaxial compressive strain) were observed, the [001] and [010] axes were mostly aligned parallel and normal to the shear direction on the shear plane, respectively. Experimental textures are compatible with orientation-producing deformation mechanisms such as dominant slip on [001](100) at 25 GPa and 1,873 K, which correspond to conditions found in the uppermost lower mantle. The dominant slip system of bridgmanite at high deviatoric stress has been reported through high-pressure experiments7, 8, 22 and theoretical calculations18, 23, as shown in Extended Data Table 1. Using a diamond anvil cell, uniaxial deformation experiments were conducted on bridgmanite at room temperature7, 22. No clear CPO pattern was observed7, probably owing to insufficient strain, whereas dominant slip systems were reported as [100], [010] and <110> on the (001) plane below 55 GPa and the (100) plane over 55 GPa (ref. 22). Uniaxial stress relaxation experiments (USRE) on bridgmanite were carried out using the Kawai-type multi-anvil press at 25 GPa and 1,673 K (ref. 8). Analysis of the recovered samples using the X-ray peak broadening technique suggested that the dominant slip direction is [100], in contradiction with our results. Dense deformation bands across the pre-existing twin boundaries were observed in the USRE8, suggesting that the bridgmanite aggregate was deformed under very high deviatoric stress. Extremely high deviatoric stress values of up to several gigapascals, induced by compression at room temperature, were directly measured during in situ USRE of olivine polymorphs24, 25. The [100] slip direction observed in USRE of bridgmanite8 might be the result of very high deviatoric stress. According to first-principles calculations23 the [100](001) slip system is one of the most easily activated slip systems of bridgmanite in the dislocation glide region. This supports the hypothesis that the slip direction observed in the USRE results from dislocation glide. On the other hand, another study based on first-principles calculations with a visco-plastic self-consistent model18 suggested that the most easily activated slip system is [010](100) at 0 K for a pressure range of 0–100 GPa in the dislocation glide region. Both calculations and previous experimental results are inconsistent with the present results. This could be due to differences in the dominant slip mechanisms or the dominant deformation mechanisms found for varying experimental conditions (for example, stress, temperature and pressure), such as in the case of olivine26. CaTiO perovskite is often used as an analogue material for bridgmanite because the SiO or TiO octahedra have similar rotation angles. Uniaxial deformation experiments were performed on CaTiO perovskite27, in which dislocation creep was expected owing to the high temperature (up to 1,973 K) and low deviatoric stress (25–120 MPa). TEM observations of the recovered sample revealed that screw dislocation with Burgers vectors [100] and [011] on the (01−1) plane, where indexing is based on the pseudo-cubic system, formed rectangular networks. The [100] and [011] directions on the (01−1) plane in pseudo-cubic indexation of perovskite include the 1/2[001] and [010] directions on the (100) plane in the orthorhombic system. The [001](100) slip system in the present study does not contradict that of CaTiO perovskite. The seismic wave anisotropy formed by the CPO of deformed bridgmanite in the present study, as shown in Fig. 3 and Extended Data Table 2, was calculated on the basis of the elastic constant (Extended Data Table 3)19. For the shear-wave anisotropy of deformed bridgmanite, the velocity of the horizontally polarized shear waves, V , is around 1% higher than that of vertically polarized shear waves, V , in horizontal flow, as shown in Fig. 3b, whereas V is 0.03%–1.10% higher in vertical flow (Fig. 3d). As shown in Fig. 4a, shear-wave splitting with V  > V is observed in the uppermost lower mantle from the Tonga–Kermadec subduction zone to the Australian continental seismic stations1, 2, where the ray path is nearly parallel to the section. The delay time ranges from 0.7 s to 6.2 s (refs 1 and 2), which corresponds to an average value of (V − V )/V ≈ 0.1%–1%, assuming a 3,000–6,000-km ray path including a 1,000–2,000-km subducted plate region11 on the uppermost lower mantle. The magnitude of the shear-wave anisotropy calculated here is consistent with deformed bridgmanite (Fig. 3b). In contrast, the opposite shear wave anisotropy (V  > V ) was observed from the Tonga–Kermadec subduction zone at the western North America stations4, where the ray path is nearly perpendicular to the section. It is thus concluded that both of the observed shear-wave anisotropies around the Tonga–Kermadec subduction zone, which are type III in the P wave tomography11, are well explained by the CPO of bridgmanite yielded by the penetration of subducted slabs down to 1,000 km by vertical motion and subsequent stagnation at similar depths, with a horizontal flow in the pyrolitic mantle (as shown in Fig. 4a). This flow pattern could be caused by the viscosity hill28, 29, 30 at depths between 1,000 km and 1,500 km, and the viscosity reduction of the slab by interconnection of ferropericlase in the post-spinel phase31. Shear wave anisotropies at the top of the lower mantle beneath the Java (type III), Peru (type III) and Kuril (type II) subducted slabs were observed along the seismic ray path nearly perpendicular or parallel to the subducted plate surface3 (Fig. 4b–d). In these observations, the fast polarizations in the shear-wave splitting appear to be arranged roughly parallel to the plane of the plate3, which is explained by the deformation-induced CPO of bridgmanite owing to flow parallel to the direction of subduction. The findings presented here on the CPO of bridgmanite, coupled with the observations of seismic anisotropy, provide a greater understanding of the direction of mantle flow, confirming inferences from seismic tomography data.

Tabebuia impetiginosa is a tree species of high economical, ornamental and medicinal value. Its seeds present short viability period and they are difficult to be stored. Thus, the objective of this study was to study the ideal conditions of moisture water content and storage temperature for preservation of Tabebuia impetiginosa seeds for one year. Firstly, the initial moisture content of the seed was determined (18.3%) and a sample was taken. The remaining seeds were submitted to drying with air circulation at 30°C, in order to obtain seeds with the water contents of 12.5, 8.4 and 4.2%. After that, the samples were stored in chambers at -10°C and 20°C and evaluated at the beginning and after 90, 180, 270 and 360 days of storage regarding percentage of germination and seedling emergence in sand. The experiment was set up in a complete random design, in a 4 x 2 factorial design with four treatments (water contents) before storage, and eight treatments (four water content x 2 thermal conditions) in each evaluation period during storage. Means were compared by the Tukey test at 5%. The preservation of Tabebuia impetiginosa seeds is favored by maintaining them with moisture degrees ranging from 4.2 and 12.5%, at -10°C, and from 4.2 to 8.4% at 20°C.

In Brazil strawberry stands out among temperate fruit trees and small fruits, the fruit being enjoyed by a large population. Currently the production systems that use fewer technologies impacting the environment and are efficient in the use of natural resources, have achieved preference among consumers highlighting the integrated production and organic production of strawberries. This with respect to the working conditions and lives of human beings and in addition to produce safer food. The spotted spider mite (Tetranychus urticae Koch) is a pest of strawberry, cosmopolitan and widespread distributed, causing damage throughout the cycle. The experiment studied the population fluctuation of spider mite in different strawberry production systems. The experiment was conducted from May to November 2008 in commercial fields in Brazil. The treatments consisted of three production systems: organic production, integrated production and conventional production. Mite population peak occurred in the dry season (June to September) and control measures recommended for integrated production systems and organic were efficient working jointly to reduce the pest population.

The search for tools to perform soil surveying faster and cheaper has led to the development of technological innovations such as remote sensing (RS) and the so-called spectral libraries in recent years. However, there are no studies which collate all the RS background to demonstrate how to use this technology for soil classification. The present study aims to describe a simple method of how to classify soils by the morphology of spectra associated with a quantitative view (400-2,500 nm). For this, we constructed three spectral libraries: (i) one for quantitative model performance; (ii) a second to function as the spectral patterns; and (iii) a third to serve as a validation stage. All samples had their chemical and granulometric attributes determined by laboratory analysis and prediction models were created based on soil spectra. The system is based on seven steps summarized as follows: i) interpretation of the spectral curve intensity; ii) observation of the general shape of curves; iii) evaluation of absorption features; iv) comparison of spectral curves between the same profile horizons; v) quantification of soil attributes by spectral library models; vi) comparison of a pre-existent spectral library with unknown profile spectra; vii) most probable soil classification. A soil cannot be classified from one spectral curve alone. The behavior between the horizons of a profile, however, was correlated with its classification. In fact, the validation showed 85 % accuracy between the Morphological Interpretation of Reflectance Spectrum (MIRS) method and the traditional classification, showing the importance and potential of a combination of descriptive and quantitative evaluations. © 2014, Scientia Agricola.

The objective of this research was to study the physiological performance of Tabebuia heptaphylla (Vell.) Toledo seeds during storage. Fruits from 15 mother plants were hand picked and placed under shade to finish drying and to ease further manual extraction of seeds. Firstly, the initial moisture content of the seeds was determined, which was 15.6%. Following that, the remaining seeds were submitted to drying at ambient temperature inside a glass desicator in order to obtain the other desired moisture contents (11.5, 8.1 and 4.3%). The samples, corresponding to the different moisture contents were stored inside chambers at temperatures of 10, 20 and -196 °C. At the beginning and after 120, 240 and 360 days of storage, the seeds were submitted to several physiological evaluations. The experiment was a factorial, in a completely randomized design, with 4 treatments (moisture contents) at beginning of storage and 12 treatments (4 moisture contents x 3 thermal conditions), in each evaluation date, during storage. Mean comparison was made by the Tukey test at 5%. It was concluded that the preservation of Tabebuia heptaphylla seeds, at water contents 15.6, 11.5, 8.1 and 4,3% is favored by temperatures from 10 and -196 °C.

Background and Purpose: The measurement of cortical shrinkage is a candidate marker of disease progression in Alzheimer's. This study evaluated the performance of two pipelines: Civet-CLASP (v1.1.9) and Freesurfer (v5.3.0). Methods: Images from 185 ADNI1 cases (69 elderly controls (CTR), 37 stable MCI (sMCI), 27 progressive MCI (pMCI), and 52 Alzheimer (AD) patients) scanned at baseline, month 12, and month 24 were processed using the two pipelines and two interconnected e-infrastructures: neuGRID (https://neugrid4you.eu) and VIP (http://vip.creatis.insa-lyon.fr). The vertex-by-vertex cross-algorithm comparison was made possible applying the 3D gradient vector flow (GVF) and closest point search (CPS) techniques. Results: The cortical thickness measured with Freesurfer was systematically lower by one third if compared to Civet 's. Cross-sectionally, Freesurfer's effect size was significantly different in the posterior division of the temporal fusiform cortex. Both pipelines were weakly or mildly correlated with the Mini Mental State Examination score (MMSE) and the hippocampal volumetry. Civet differed significantly from Freesurfer in large frontal, parietal, temporal and occipital regions (p<0.05). In a discriminant analysis with cortical ROIs having effect size larger than 0.8, both pipelines gave no significant differences in area under the curve (AUC). Longitudinally, effect sizes were not significantly different in any of the 28 ROIs tested. Both pipelines weakly correlated with MMSE decay, showing no significant differences. Freesurfer mildly correlated with hippocampal thinning rate and differed in the supramarginal gyrus, temporal gyrus, and in the lateral occipital cortex compared to Civet (p<0.05). In a discriminant analysis with ROIs having effect size larger than 0.6, both pipelines yielded no significant differences in the AUC. Conclusions: Civet appears slightly more sensitive to the typical AD atrophic pattern at the MCI stage, but both pipelines can accurately characterize the topography of cortical thinning at the dementia stage. © 2015 Redolfi et al.

Respondents from Singapore report that their organizations have either implemented (46 percent) or plan to expand open source implementation (14 percent), while 40 percent of respondents plan to implement open source solutions within the next 12 months, motivated by benefits such as faster implementation and improved flexibility, which can enable organizations to deliver new customer experiences, services, and products more quickly. Business and IT priorities in the next 12 Months The survey results identified that, in order to successfully compete in the age of the customer and continue to deliver world-class operational capabilities, respondents from Singapore plan to focus on three IT and business priorities in the next 12 months: The above priorities have been reflected in respondents' strategic IT initiatives in the next 12 months to transform both internal and customer facing technologies: The research predicts that over the next two to three years, the role of open source will accelerate. Survey respondents from Singapore anticipate that their organization's use of open source may increase by 50 percent as part of their agile hybrid cloud infrastructure and by 62 percent in application development and DevOps environments. "Many anticipate that the pace of digital disruption will only pick up, causing wider and deeper impact on businesses, and every industry may soon find a digital competitor. It is more urgent than ever for organizations to find their own competitive advantage through technology. With this shift, open source has evolved to play an increasingly strategic role as a default choice for technology innovation to help businesses improve their agility, efficiency and innovation." "It is encouraging to see that 60 percent of respondents in Singapore have been thinking beyond the traditional approaches and are taking a cue from the companies championing digital innovation through open source. Working closely with enterprises, we have witnessed first-hand the power of open source. It is no longer only an IT initiative, but a strategy to create real business impact by transforming and modernizing complex IT challenges and accelerating innovation and agility." From "Open Source Drives Digital Innovation", a [November 2016] commissioned study conducted by Forrester Consulting on behalf of Red Hat "Digitally empowered customers have taken the driver's seat from organizations that once had the power. Keeping pace with the growth of customer expectations can no longer be achieved within the four walls of an organization. Hence enterprises in Asia Pacific should tap into external and increasingly open source technology, talent, insight and innovation." This research was commissioned by Red Hat and completed in September 2016.Forrester Consulting conducted a computer-assisted telephone interviewing (CATI) survey of 455 senior IT decision-makers and CIO's across 9 countries/regions in Asia-Pacific (Australia, Mainland China, Indonesia, India, Japan, Korea, Malaysia, Singapore and Taiwan). The custom survey was completed with organizations having 1,000 or more employees. Survey respondents included are from organizations in the financial services, government, healthcare and telecommunication industries.
