Health Indicator Bacteria That Is Useful for Risk Assessment of Peri-Implantitis

We established a novel identification method for oral Rothia species using one-step multiplex PCR analysis to investigate whether the monitoring of oral Rothia species levels is useful for peri-implantitis risk assessment, and to examine the oxygen concentration that these organisms need for growth in vitro. The mean number and proportion of Rothia aeria in peri-implant sulcus fluid (PISF) samples was significantly higher in the healthy implant group than in the peri-implantitis group (P < 0.05). Moreover, R. aeria under aerobic conditions vigorously grew compared with those under anaerobic conditions, and this organism grew only at the upper layer where high oxygen concentrations existed in a semi-liquid nutrient medium. Therefore, the monitoring of R. aeria levels may be suitable as an indicator of healthy peri-implant tissue conditions for the prevention of peri-implantitis.

Topographic, lithospheric and lithologic controls on the transient landscape evolution after the opening of internally-drained basins. Modelling the North Iberian Neogene drainage

The opening of internally-drained (endorheic) sedimentary basins often leads to a major drainage change, re-excavation of the basin sedimentary infill, and transient landscape. The timing of such basin openings can be dated only in exceptional cases in which the youngest sedimentary infill remains preserved. For this reason, the processes and timing involved in their transient landscape evolution are poorly known. We explore the role of erodibility, basin geometry and flexural isostasy during the capture of internally-drained basins by means of numerical modelling techniques constrained by recent terrace cosmogenic dating and geomorphological analysis, addressing the issue as to why the Duero and Ebro rivers, draining two Cenozoic sedimentary basins in N Iberia with similar geographical dimensions and drainage histories, have undergone a markedly different erosion evolution leading to distinctly different present morphology. To evaluate how these intrinsic parameters affect the transient landscape evolution, we design a synthetic scenario inspired by those basins. The results show that, once a basin becomes externally drained, its drainage integration and erosion rates are strongly dependent on (1) the basin elevation above the base level; (2) the width of the topographic barrier, (3) its erodibility; and (4) the rigidity of the lithosphere. The results show that transient landscape evolution can last for tens of millions of years even in absence of tectonic activity and changes in base level or climate. Basins isolated by wide and resistant barriers such as the Duero Basin may undergo a multi-million-year time lag between drainage opening and basin-wide incision. In the case of the Duero Basin, this delay may explain the paradoxical time lag between the last lacustrine bulk sedimentation dated at 9.6 Ma and the onset of widespread basin incision variously estimated at 3.7 to 1 Ma.
Effectiveness Against White Sharks of the Rpela Personal Shark Deterrent Device Designed for Surfers

Many shark bites to humans, including fatalities, have involved surfers. Various personal shark deterrents are commercially available to surfers, including Rpela v2, which is a battery-powered device fitted to a surfboard. It produces an electric field around the surfer aimed at deterring sharks from approaching or biting by disrupting their electroreception organs. The device was tested on white sharks (Carcharodon carcharias) at Salisbury Island, Western Australia. In total, 46 trials were done with the Rpela v2 either active or not active to determine the device's effect on sharks' response to a floating board with fish bait attached (to tempt a bite). When active, Rpela v2 significantly reduced the probability of a bite (0.75 to 0.25, a 66% reduction) and interaction (i.e. bite or touch) (0.80 to 0.50, a 38% reduction) occurring compared with when it was inactive. The number of passes taken by a shark also reduced and the mean distance between the shark and the bait increased when Rpela v2 was active. It is noted that Rpela v2 did not completely remove the risk of shark bite, but the magnitude of the reduction in risk is of a level that surfers are likely to consider meaningful and it could be expected that Rpela v2 would provide more time for surfers to leave the water (i.e. as inferred from the number of passes) when a potentially dangerous shark is present. Implications for the role of personal deterrents in strategic management of the risk of shark bite are also discussed.
An inquiry into the linkages between university ecosystem and students’ entrepreneurial intention and self-efficacy

ABSTRACT The purpose of this article is to evaluate the impact of university ecosystems on entrepreneurial intention and self-efficacy of Brazilian undergraduate students. The empirical exercise relies on Structural Equations Modelling based on data of 468 students from 70 universities across the country. Results indicate that traditional approaches to foment entrepreneurship are less effective than nurturing linkages between universities and the broader entrepreneurial ecosystem, and that private universities are more effective in promoting entrepreneurial behaviour. From a practical standpoint, our assessment suggests the need for universities to approach entrepreneurial education in a more flexible way, fostering interactions with businesses.
Sorghum Grain and Stover Nutrient Concentrations as Influenced by Tillage and Soil Amendment in Semi-Arid Burkina Faso

Sorghum [Sorghum bicolor (L) Moench) is a major grain crop in Burkina Faso. Two three-year experiments were conducted in the Sudanian and Sudano-Sahelian zones to determine how plant nutrient concentrations are affected by tillage methods (T) and soil amendments (SA). In both locations, T and SA had little effect on grain and stover nutrient concentrations with some cases of inconsistency across years. Some nutrient concentrations differed by year. The grain nutrient concentrations of N, P, Mg, S, Zn, and Fe were adequate for human nutrition at both locations, but deficient for K, Ca, Mn and Cu. Sorghum nutrient concentrations for feeding cattle were adequate for K, Ca, Mg, S, Mn, and Zn in most cases at both locations but low for N, P, and Cu. The stover N and P concentrations also appeared to be deficient for optimal plant growth. In both agroecological zones, nutrient applications or genetic enhancement to improve deficient nutrient concentrations, or use of diverse foodstuffs, or biofortified sorghum to provide deficient nutrients in human and cattle diets is needed to meet dietary requirements. In addition to grain and stover yield, studies need to evaluate grain nutrient and stover nutrient concentrations to meet human and cattle dietary requirements.
Regular recreational Cannabis users exhibit altered neural oscillatory dynamics during attention reorientation

Abstract Background Cannabis is the most widely used illicit drug in the United States and is often associated with changes in attention function, which may ultimately impact numerous other cognitive faculties (e.g. memory, executive function). Importantly, despite the increasing rates of cannabis use and widespread legalization in the United States, the neural mechanisms underlying attentional dysfunction in chronic users are poorly understood. Methods We used magnetoencephalography (MEG) and a modified Posner cueing task in 21 regular cannabis users and 32 demographically matched non-user controls. MEG data were imaged in the time−frequency domain using a beamformer and peak voxel time series were extracted to quantify the oscillatory dynamics underlying use-related aberrations in attentional reorienting, as well as the impact on spontaneous neural activity immediately preceding stimulus onset. Results Behavioral performance on the task (e.g. reaction time) was similar between regular cannabis users and non-user controls. However, the neural data indicated robust theta-band synchronizations across a distributed network during attentional reorienting, with activity in the bilateral inferior frontal gyri being markedly stronger in users relative to controls (p's < 0.036). Additionally, we observed significantly reduced spontaneous theta activity across this distributed network during the pre-stimulus baseline in cannabis users relative to controls (p's < 0.020). Conclusions Despite similar performance on the task, we observed specific alterations in the neural dynamics serving attentional reorienting in regular cannabis users compared to controls. These data suggest that regular cannabis users may employ compensatory processing in the prefrontal cortices to efficiently reorient their attention relative to non-user controls.
A Simple Route to Ruthenium Sulfide Nanoparticles via Thermal Decomposition of Precursor Complexes

The research work presented here investigate the use of homonuclear tris-dithiocarbamato ruthenium(III) complexes as single-source molecular precursors to ruthenium sulfide nanoparticles. The dithiocarbamate ligands with their respective precursor complexes were characterized by UV-Vis, FTIR, 1H- and 13C-NMR, and in addition TGA was used for precursors. The absorption spectra confirmed the geometry of tris-chelate ruthenium complexes [Ru(S2CNR2)3] to be octahedral and were very stable both in solution and in the solid state. The optical and structural properties of the ruthenium sulfide nanoparticles were examined using FTIR, XRD, EDS, SEM, TEM, UV-Vis and photoluminescence (PL). FTIR studies revealed that Ru2S3 nanoparticles are capped through the interaction of the –NH2 group of hexadecylamine (HDA) adsorbed on the surfaces of nanoparticles with the prominent band observed around 3330 cm-1 due to v(N-H). The XRD confirmed the successful formation of ruthenium sulfide nanoparticles with a cubic crystal structure within the nano-scale range. The optical band gap(Eg) determined from Tauc plot was found in the range (3.44 to 4.18 eV) values.
Ferrite-to-Austenite and Austenite-to-Martensite Phase Transformations in the Vicinity of a Cementite Particle: A Molecular Dynamics Approach

We used classical molecular dynamics simulation to study the ferrite–austenite phase transformation of iron in the vicinity of a phase boundary to cementite. When heating a ferrite–cementite bicrystal, we found that the austenitic transformation starts to nucleate at the phase boundary. Due to the variants nucleated, an extended poly-crystalline microstructure is established in the transformed phase. When cooling a high-temperature austenite–cementite bicrystal, the martensitic transformation is induced; the new phase again nucleates at the phase boundary obeying the Kurdjumov–Sachs orientation relations, resulting in a twinned microstructure.
Control-style ambidexterity and information systems project performance: an expanded view of control activities

ABSTRACT Information systems (IS) projects represent key building blocks of large-scale digital transformation and innovation initiatives. As a result, IS projects have become increasingly ambitious in terms of both goals and scale, making it even more challenging for managers to exercise control over such projects. While prior research focused primarily on the direct and interactive effects of formal and informal control modes on IS project performance, recent research directs attention to the importance of considering project managers’ control styles (i.e., how managers interact with controlees to enact controls). Corresponding studies also indicate that “either/or” control approaches – as opposed to “both/and” approaches – are no longer viable in today’s complex environment. As such, our study draws on an ambidexterity perspective to theoretically develop and empirically test the direct and interactive effects of control-style ambidexterity on IS project performance. Using matched-pair data from 146 IS projects (from 146 high-tech firms), we find that control-style ambidexterity improves project performance – directly and in combination with both formal and informal control. The study results contribute novel insights regarding the effective control of IS projects in the digital era and help explain mixed findings in prior literature, thereby facilitating continued theory development in the research area.
Optimal structure of a water cooled pin fin heat sink by Taguchi method depending on various requirements

Prediction and optimization of water-cooling performance of a pin fin heat sink with variable pin diameters along a flow direction is attempted. We have developed a simple analyze procedure for pin fin heat sink that enables to evaluate the row-by-row performance when diameters of fins are morphed along a flow direction. Validity of the procedure is confirmed for uniform and non-uniform pin diameter cases. The Taguchi method is applied to an optimization method. Optimal design among the considered cases, in which the thermal resistance is minimum, corresponds to the configuration where the pin diameter equals 3 mm constructed from copper. This holds for constant inlet velocity and constant pumping power cases. Optimum structure of heat sink considering simultaneous parameters (minimum thermal resistance, pressure drop and mass) occurs when the heat sink is built from aluminum with a pin diameter of 2 mm. These three parameters influence the design of the heat sink. For instance, when the thermal resistance and the pressure drop are significant, optimum structure is a “wing like shape” with larger pin diameter near the central rows and copper as material. However, when the thermal resistance and the heat sink mass are of interest, the optimum structure associated with the larger pin diameter constructed from aluminum. Also, when we consider the pressure drop and heat sink mass, the optimum design is the one where the pin diameter is 1 mm built from aluminum.
Holocene regional climate change and formation of southern Ontario's largest swamp inferred from a kettle-lake pollen record

Abstract Greenock Swamp wetland complex is one of few remaining natural wetlands in the Great Lakes region and, at 89 km2 in areal extent, is currently the largest hardwood swamp in southern Ontario, Canada. We present here pollen and sediment records from a kettle hole (Schmidt Lake) and adjacent Thuja occidentalis swamp to reconstruct regional paleoclimate and vegetation history, and to assess the timing and development of the swamp ecosystem and associated carbon stocks. Pollen-inferred paleoclimate reconstructions show the expected warming in the Early Holocene, and indicate the Mid-Holocene initiation of lake-effect snow. This enhanced snowfall may have maintained high water tables in the adjacent wetland since ca. 8300 years ago, promoting the establishment of a swamp dominated by Thuja occidentalis. Carbon accumulation rates in a >2-m-long peat core collected from a Thuja occidentalis stand adjacent to Schmidt Lake are 30–40 g C/m2/yr, which is higher than the average of northern high-latitude peatlands. Using topographic and hydrological parameters, we estimated that mean swamp peat thicknesses could exceed 2 m. Thus, this study encourages future investigations on temperate swamps from the perspective of hitherto underestimated Holocene carbon sinks and shows the importance of regional hydroclimate in supporting swamp ecosystems.
Developing firm capabilities to utilise social media for the fuzzy front end of innovation

ABSTRACT Despite the growing importance of using social media to leverage external knowledge for new product development (NPD) in innovation, few studies have examined firm capabilities that underpin this knowledge acquisition route. This paper provides an empirical examination of firm capabilities that leverage external knowledge, utilising social media for the fuzzy-front-end (FFE) phase of the NPD process. With evidence from 27 interviews conducted with executives’ from large fast moving consumer goods (FMCG) firms, a thematic analysis using NVivo 12 is used to develop a conceptual framework capturing the key capabilities for using social media in the FFE. The findings reveal that the utilisation of social media is an ongoing process of experimenting with new technologies within the NPD phase of a firm’s innovation efforts. Hence, the results of the study suggest FMCG firms may consider developing the following capabilities to help effectively acquire external knowledge via social media: use staff specialised in social media for external knowledge identification; dedicate an independent department for social media knowledge acquisition; and encourage an open innovation culture.
Drawdown of Atmospheric pCO2 Via Variable Particle Flux Stoichiometry in the Ocean Twilight Zone

The strength of the biological soft tissue pump in the ocean critically depends on how much organic carbon is produced via photosynthesis and how efficiently the carbon is transferred to the ocean interior. For a given amount of limiting nutrient, phosphate, soft tissue pump would be strengthened if the carbon (C) to phosphorus (P) ratio of sinking organic matter increases as the remineralization length scale of C increases. Here, we present a new data compilation of particle flux stoichiometry and show that C:P of sinking particulate organic matter (POM) in the ocean twilight zone on average is likely to be higher than the C:P ratio of surface suspended POM. We further demonstrate using a physics‐biology coupled global ocean model combined with a theory from first principles that an increase in C:P export flux ratio in the ocean's twilight zone can lead to a considerable drawdown of atmospheric pCO2.
Android-Based Waste Education App: An Information Media on Zero-Waste Programs

Zero waste is one of the programs from the government of West Nusa Tenggara Province in Indonesia, where this program aims to provide education about waste to the public so that the waste can be processed or recycled so that it can be useful. Therefore, for the sake of creating a zero waste culture in the community, it is necessary to have media that provide education to the public about this program. The purpose of this article is to discuss the process of developing an Android-based waste education application as a medium of information about zero waste. This study uses the ADDIE model to make this product with five steps, namely analysis, design, development, implementation and evaluation. The data collection technique used was a questionnaire with a Likert scale, and the subjects in this study were the 60 people in the Menceh village. The data analysis technique used is descriptive quantitative. Our findings show that this application (media) is declared very-feasible by material (content) experts with a score of 85% and media (design) experts (83%), and user usability is in the very-high category (83%). So it can be concluded that this application is feasible to use properly, so that users can obtain information about how to manage waste through a zero waste program.
Establishment of Reference Values of Gamma-Glutamyl-Transferase and Plasma Aminotransferases in Young Congolese

Objectives: Our goal was to contribute to the production of reference values ​​of plasma or serum biochemical markers by determining the reference values ​​of gamma-glutamyltransferase (GGT), aspartate aminotransferase (ASAT) and alanine aminotransferase (ALAT) in young Congolese presumed to be healthy. Methods: 250 young Congolese presumed to be healthy (125 boys and 125 girls) aged 15 to 25 participated in the study. They were selected according to anamnestic and clinico-biological criteria. Samples were taken on a tube containing EDTA and the resulting plasma was stored at -20 ° C. The KENZA MAX spectrophotometer was used to analyze GGT, ASAT and ALAT. The median and the 2.5-97.5 percentiles were used to set the reference limits for each enzyme. The benchmarks determined were compared with those reported by other Africans, Europeans, Indians and Americans. Results: The established reference values ​​were: GGT 12.15-61.85 IU/L for boys and 7-51.95 IU / l for girls (p˂0.0001); ASAT 21.60-94.85 IU/L for boys and 17-84.85 IU/L for girls (p = 0.0003); ALAT 8.30-74.40 IU/L for boys and 8-53.85 IU/L for girls (p˂0.0001). In addition, the comparison between our values ​​and those of other populations showed significant differences. Conclusion: Our results underline the importance of establishing reference values ​​for plasma enzymes specific to the Congolese population. The use of the values ​​established in the ’other populations could induce errors of judgment by excess or by default. Key words: Gamma-glutamyltransferase, Aspartate aminotransferase, Alanine aminotransferase, Reference values, Congo.
Effect of hydrothermal reaction temperature on the photocatalytic properties of CdWO4-RGO nanocomposites

Cadmium tungstate (CdWO4) nanorods and CdWO4-reduced graphene oxide (RGO) nanocomposites have been prepared by the hydrothermal method at 140, 160 and 180 oC reaction temperatures. The synthesized samples were characterized by X-ray powder diffraction, scanning electron microscopy (SEM), Fourier transform infrared, photoluminescence spectroscopy and Raman spectroscopy. SEM image showed the pure sample consist of nanorods with 50-100 nm diameter and ~1 µm length. The images of the nanocomposite samples clearly showed existence of CdWO4 nanorods and graphene sheets together. The photocatalytic activities of the as-prepared samples were investigated by degradation of methylene blue under the visible light irradiation. An enhancement in photocatalytic activity was observed with CdWO4-RGO nanocomposites in compare with the pure CdWO4. The effect of reaction temperature on the photocatalytic activity of the prepared nanocomposites was also investigated. The results showed that the CdWO4-RGO sample which prepared at 160 oC has more catalytic activity than the other samples.
