Evaluation of the safety and efficiency of novel metallic ultrasonic scaler tip on titanium surfaces.

AIM To evaluate the safety and efficiency of novel ultrasonic scaler tips, conventional stainless-steel tips, and plastic tips on titanium surfaces. MATERIAL AND METHODS Mechanical instrumentation was carried out using conventional ultrasonic scalers (EMS, Nyon, Switzerland) with novel metallic implant tip (BS), a plastic-headed tip (ES), a plastic tip (PS) and a conventional stainless-steel tip (CS) on 10 polished commercially pure titanium disks (Grade II) per group. Arithmetic mean roughness (R(a) ) and maximum height roughness (R(y) ) of titanium samples were measured and dissipated power of the scaler tip in the tip-surface junction was estimated to investigate the scaling efficiency. The instrumented surface morphology of samples was viewed with a scanning electron microscope (SEM) and surface profile of the each sample was investigated using contact mode with a commercial atomic force microscope (AFM). RESULTS There were no significant differences in surface roughness (R(a) and R(y) ) among BS, ES, and PS group. However, CS group showed significant higher surface roughness (R(a) and R(y) ). The efficiency of CS tip is twice as much higher than that of BS tip, the efficiency of BS tip is 20 times higher than that of PS tip, and the efficiency of BS tip is 90 times higher than that of ES tip. CONCLUSION Novel metallic copper alloy ultrasonic scaler tips may minimally influence the titanium surface, similar to plastic tip. Therefore, they can be a suitable instrument for implant maintenance therapy.
Oxygen self-diffusion along high diffusivity paths in forsterite.

Diffusion profiles of 18O tracer in single crystals of forsterite following anneals at 1100° and 1200°C have been determined by a depth profiling technique using secondary ion mass spectrometry. The diffusion penetration profiles showed error function forms with developed tails. The profiles were analyzed in terms of diffusion in the forsterite lattice together with a contribution from dislocation. The present results of lattice diffusion lie in the range of the extrapolation of lines on Arrhenius plots reported previously for intracrystalline diffusion in forsterite. The dislocation diffusion coefficients are about 104 times faster than the lattice diffusion at the same temperature. Diffusion along the dislocations takes place within a pipe with radius of about 0.1 nm surrounding the dislocation line. Based on the above results, O diffusion along high diffusivity paths, such as dislocations and grain boundaries, play an important role on the diffusional creep in olivine under laboratory condition.
A case study of termite mound occurrence in relation to forest edges and canopy cover within the Barandabhar forest corridor in Nepal

The Barandabhar forest corridor (BFC) in the Royal Chitwan National Park is an example of a buffer zone implemented to mitigate the effect of local communities on conservation and the effect of conservation on local communities. However, the effectiveness of these actions for conservation may depend on the intensity of human activity and the species considered. We conducted a field survey within the BFC to study how termite mound occurrences relate to forest edges, human activity and canopy cover, and to examine the spatial patterns of the edge effect in terms of dead wood availability, logging and canopy cover. The results show that termite mound abundance was significantly affected by edge effects such that the abundance increased from ~5 mounds/ha along the edge to ~14mounds/ha in the core areas 2 km inside the forest. The forest edge was partly defined by decreased canopy cover and increased signs of logging. Our results suggest that buffer zone practices may be a valid method to mitigate edge effects on termites in core areas. However, we also found indications of human activities effecting canopy cover that could influence the effectiveness of buffer zone management in this area.

Estimating the Impact of Vadose Zone Sources on Groundwater to Support Performance Assessment of Soil Vapor Extraction

Soil vapor extraction (SVE) is a prevalent remediation remedy for volatile organic compound (VOC) contaminants in the vadose zone. To support selection of an appropriate condition at which SVE may be terminated for site closure or for transition to another remedy, an evaluation is needed to determine whether vadose zone VOC contamination has been diminished sufficiently to keep groundwater concentrations below threshold values. A conceptual model for this evaluation was developed for VOC fate and transport from a vadose zone source to groundwater when vapor‐phase diffusive transport is the dominant transport process. A numerical analysis showed that, for these conditions, the groundwater concentration is controlled by a limited set of parameters, including site‐specific dimensions, vadose zone properties, and source characteristics. On the basis of these findings, a procedure was then developed for estimating groundwater concentrations using results from the three‐dimensional multiphase transport simulations for a matrix of parameter value combinations and covering a range of potential site conditions. Interpolation and scaling processes are applied to estimate groundwater concentrations at compliance (monitoring) wells for specific site conditions of interest using the data from the simulation results. The interpolation and scaling methodology using these simulation results provides a far less computationally intensive alternative to site‐specific three‐dimensional multiphase site modeling, while still allowing for parameter sensitivity and uncertainty analyses. With iterative application, the approach can be used to consider the effect of a diminishing vadose zone source over time on future groundwater concentrations. This novel approach and related simulation results have been incorporated into a user‐friendly Microsoft® Excel®‐based spreadsheet tool entitled SVEET (Soil Vapor Extraction Endstate Tool), which has been made available to the public.

Scattering of radio waves by the F-region of the ionosphere

Records are reproduced showing diffuse echoes from the F-region of the ionosphere received continuously at night in equatorial regions over a wide range of wave-frequency. Tney are interpreted as due to Rayleigh scattering by spatial irregularities in the distribution of electron-density at or above a definite level in the F-region. Because of the highly dispersive nature of the ionosphere, there is no marked dependence of Rayleigh scattering upon wave-frequency such as there is for a non-dispersive medium. According to this interpretation, variation of the maximum wave-frequency to which diffuse echoes can be followed has nothing to do with variation of the maximum electron-density of an ionospheric region, but merely indicates variation in the size of irregularities in electron-density. Scattering of this type may have some bearing upon the phenomenon of persistence of E-region echoes to wave-frequencies greater than the critical penetration-frequency of the E-region.
Men’s views and experiences of infant feeding: A qualitative systematic review

4 While the advantages of breastfeeding are well documented, rates for breastfeeding often fall 5 short of international and national targets. Increasing attention has been paid to the role of 6 men in infant feeding but a lot of the research about men has been elicited from women, 7 rather than from men themselves. To explore these issues further, a systematic review of the 8 qualitative research on infant feeding was carried out, focusing specifically on men’s own 9 views and experiences. Evidence was identified by searching electronic databases (CINAL, 10 Cochrane, PubMed and Scopus), manually searching citations, and by searching the grey 11 literature. Studies were included in the review if they discussed men’s views and experiences 12 of infant feeding and if they reported primary qualitative data. A total of 20 research papers 13 were included in the review and each study was summarised and then analysed thematically 14 to produce a synthesis. Five major analytical themes were identified: men’s knowledge of 15 infant feeding; men’s perceptions of their role in infant feeding; positive views on 16 breastfeeding; negative views on breastfeeding; and, men’s experiences of health promotion 17 and support. The review concludes by highlighting that while men can play an important role 18 in supporting women, they do not have a significant role in infant feeding decisions. 19 20 INTRODUCTION 21 In May 2016, the World Health Organisation (World Health Organisation, 2016a) endorsed 22 global targets for improving infant, young child and maternal nutrition including the aim to 23 ‘increase the rate of exclusive breastfeeding in the first 6 months up to at least 50%’ in order 24 ‘to achieve optimal growth, development and health’ (World Health Organisation 2016b). 25 The beneficial short and long-term health effects of breastfeeding for both mother and baby, 26
The Pelitic Hornfelses of the Cashel-Lough Wheelaun Intrusion, County Galway, Eire

The pelitic envelope of a basic and ultrabasic intrusion, together with the pelitic xenoliths, have been studied by field and microscopic examination, and 14 chemical analyses of the hornfelsed pelites are given. Eighteen chemical analyses of unhornfelsed pelites from the region are available for comparison. There was every gradation from biotite-acid andesine-quartz-fibrolite-garnet "regional" schist through cordierite-prismatic sillimanite-labradorite-magnetite-biotite hornfels to spinel-magnetite-cordierite $\pm$ corundum $\pm$ orthopyroxene hornfels as desilication and dealkalization occurred. The $SiO_2$ content, 46.2 per cent, and $Na_2O + K_2O$ content, 6.2 per cent, in the average unhornfelsed nearby pelite fell in the xenoliths to less than 10 per cent $SiO_2$ and less than 0.25 per cent alkali, while the $FeO + Fe_2O_3$, 12.0 per cent, and MgO, 3.4 per cent, rose to over 40 per cent and 9 per cent, respectively. It is suggested that the composition of the material removed from the xenoliths to the ultrabasic magma had a composition resembling, but not identical with, that of Daly's average subalkaline granite, which result supports Bowen's theory of the interaction of basic magma and petlite.
Buoyant Eddies Entering the Labrador Sea Observed with Gliders and Altimetry

Abstract Intense, buoyant anticyclonic eddies spawned from the west Greenland boundary current were observed with high-resolution autonomous Seaglider hydrography and satellite altimetry as they entered the Labrador Sea interior. Surveys of their internal structure establish the transport of both low-salinity water in the upper ocean and warm, saline Irminger water at depth. The observed eddies can contribute significantly to the rapid restratification of the Labrador Sea interior following wintertime deep convection. These eddies have saline cores between 200 and 1000 m, low-salinity cores above 200 m, and a velocity field that penetrates to at least 1000 m, with 0–1000-m average speeds exceeding 40 cm s−1. Their trajectory, together with earlier estimates of the gyre circulation, suggests why the observed region of deep convection is so small and does not occur where wintertime cooling by the atmosphere is most intense.

Effects of Antipsychotics on Arrhythmogenic Parameters in Schizophrenia Patients: Beyond Corrected QT Interval

Purpose Antipsychotic drugs have been implicated as risk factors for QT prolongation, which is a predictor of sudden cardiac death. However, the QT interval is considered an imperfect marker for proarrhythmic risk. Recently, improved methods, namely, QT dispersion (QTD), QTD ratio (QTDR), T wave peak-to-end interval (Tp-e), Tp-e/QT ratio and Tp-e/QTc ratio, have been regarded as proarrhythmic risk markers. We attempted to reevaluate the risk of sudden cardiac death due to antipsychotics use by measuring these improved evaluation methods. Patients and Methods We retrospectively evaluated QTc, QTD, QTDR, Tp-e, Tp-e/QT ratio and Tp-e/QTc ratio from the medical records of 410 patients with schizophrenia diagnosed by the Diagnostic and Statistical Manual of Mental Disorders, 4th Edition, Text Revision, or 5th Edition. Information on drugs administered was obtained from medical records. We investigated the correlation between each index on ECG and medication, such as antipsychotics, prescribed to participants with linear regression analysis. We also compared each index between 235 healthy controls and 235 patients matched for age and sex. Results Positive correlations between QTc and levomepromazine and brexpiprazole were identified. Levomepromazine and lithium were positively correlated with QTD. Levomepromazine, quetiapine, asenapine, clozapine and carbamazepine were positively correlated with QTDR. Levomepromazine, olanzapine, brexpiprazole and lithium were positively correlated with Tp-e. Olanzapine, brexpiprazole and lithium were positively correlated with the Tp-e/QT ratio. Olanzapine, brexpiprazole and lithium were positively correlated with Tp-e/QTc ratio. Significant differences in all indexes were noted between the patients and healthy controls. Conclusion According to our results, the prediction of the risk of sudden cardiac death by each index was inconsistent. We should evaluate the predictive factor of ventricular arrhythmia according to various electrocardiogram indexes because QTc alone could not identify the risk of sudden cardiac death.
On the modification of tides in shallow water regions by wind effects

The influence of non-linear effects upon tides in shallow coastal regions, due to the presence of a significant storm surge is examined using a two-dimensional model of the west coast of Britain. The model has an unstructured grid, designed to have a high resolution mesh in the near coastal region of the eastern Irish Sea, the area chosen as the focus of this study. The influence of tide-surge interaction upon the M2, M4 and M6 components of the tide, due to surges produced by steady uniform wind stresses is examined in detail. Calculations show that in deep regions the tide is unaffected by the surge. However, in shallow coastal regions there is significant modification of tidal elevations and currents. This arises because of changes in bottom stress, and the non-linear interaction term in the hydrodynamic equations. In addition the locations of regions that “wet and dry” are changed during the tidal cycle due to the influence of the surge. This gives rise to significant spatial variations and changes in magnitude of the tide and its higher harmonics depending upon wind stress direction and water depth. These results explain why tidal energy remains in the surge residual in shallow water when it is computed by de-tiding the total signal using a tide only calculation; an effect often found in observed surge residuals
Mechanical Stresses, Arterial Stiffness, and Brain Small Vessel Diseases Shimanami

causes Background Purpose stiffness, a risk factor of brain vessel diseases (SVD), causes hemodynamic changes. Mechanical stresses, circumferential wall tension (WT), and shear stress (SS) may change with arterial stiffness and be related to SVD. We investigated the associations between mechanical stresses and arterial stiffness and SVD.
Mesoarchean to Mesoproterozoic Evolution of the Southern Gawler Craton, South Australia

The Gawler Craton preserves a complex and prolonged tectonic history spanning the interval c. 3200-1500 Ma. Reworking of Paleoarchean, c. 3400-3250 Ma crust led to the formation of c. 3150 Ma granites now exposed within a narrow belt in the eastern Gawler Craton. Following this, there is no known record of significant tectonic activity until the onset of bimodal magmatism during the Neoarchean to earliest Paleoproterozoic, c. 2560-2470 Ma. This magmatism was terminated by high temperature metamorphism and deformation during the 2465-2410 Ma Sleafordian Orogeny. Magmatic events associated with widespread sedimentation over the interval c. 2000-1740 Ma largely sources this older crust. The c. 1730-1690 Ma Kimban Orogeny reworked these Paleoproterozoic basins and the Neoarchean basement in a pre-dominantly transpressional orogenic system. Juvenile mantle input followed by widespread crustal melting occurred over the interval c. 1620-1570 Ma. This period of intense magmatism initiated with emplacement of the relatively juvenile c. 1620-1608 Ma St Peter Suite. This was followed by the economically significant c. 1600-1570 Ma Gawler Range Volcanics/Hiltaba Suite magmatic event, which resulted from widespread mid-crustal melting. Synchronous deformation and high temperature metamorphism accompanied the Gawler Range Volcanics/Hiltaba Suite magmatic event indicating it occurred in an orogenic environment. Far field stress was distributed around a central core zone of largely undisturbed Gawler Range Volcanics with deformation localised in the northern and southern Gawler Craton. The Gawler Range Volcanics/Hiltaba Suite magmatic event resulted in formation of a province of major economic significance that includes the giant Olympic Dam Cu-Au-U ore body.
Population, Development, and Environment on the Yucatan Peninsula: From Ancient Maya to 2030

This volume is the third in a series of case studies of population, development, and environment interactions. In the style of the other two studies this report is divided into two parts. The first part is a set of studies of the history, culture, environment, and economy of the Yucatan peninsula. The chapters in this part focus on issues ranging from the causes of the Mayan collapse in the tenth century to the performance of the Yucatan economy from 1970 to 1993. The second part builds on the first through the construction of a set of computer simulation models of population, development, and environment interactions. Taken together, the models deal with population growth by education, migration between the Yucatan and other parts of Mexico and within the peninsula itself, tourism, the quality of beaches, the congestion of historical sites, the fisheries of the Yucatan coast, and land use.

The Effects of Using Peer Tutors for Visually Impaired Students in Physical Education

The integration of students with visual impairments is becoming more common in public schools. With this integration, challenges arise relative to academic learning time in physical education (ALT-PE). According to Wiskochil, Lie-berman, Houston-Wilson, and Pe-tersen (2007), some of the reasons for this may include reduced participation opportunities compared to sighted peers, apathetic teachers , or teachers without the skills and knowledge to appropriately include visually impaired students. Research has supported the use of peer tutors as an effective and cost-effi cient means of increasing the success of students with visual impairments in general physical education classes (Fernandez-Vivo 1997). The Wiskochil et al. study (1) examined how peer tutors affect visually impaired students' ALT-PE scores, (2) compared the effects of trained and untrained tutors , and (3) compared the effects of peer tutors on visually impaired stu-dents' performance of open and closed activities. Data were collected from four students with visual impairments (two with low vision and two who were blind) and from two to four same-aged, same-gendered peer tutors from each of their integrated physical education classes. Visually impaired students (tutees) were chosen from several different grade levels and from different schools in the western New York area. Two to four tutors were selected from each tutee's integrated physical education class and were trained to ensure consistent and skilled tutoring throughout the study. At each site, the primary researcher and physical education teacher chose a sighted classmate with skills comparable to those of the visually impaired participant to serve as a comparison of time spent in physical education. After the selection process, each tutee was videotaped in four to fi ve physical education classes to establish a stable baseline. Once the tutors were trained, all participants were videotaped for six to eight physical education classes as documentation of the intervention. Throughout the intervention phase, the primary investigator monitored and gave feedback to the tutors and met with them before and after each class. Researchers established inter-observer and intra-observer reliability above 90 percent for all ALT-PE scores. Researchers found that all tutees increased their ALT-PE mean percentages with the intervention of same-aged, same-gendered peer tutors. The two students with no vision improved their mean ALT-PE scores by 38.8 percent and 10.7 percent, respectively. One student with low vision improved his mean ALT-PE scores by 29.6 percent. The other low-vision participant showed less improvement following the intervention, possibly due to her previous …
