Comparison of removal torque of dual-acid etched and single-acid etched implants in rabbit tibias

The relationship between dental implants and bone was developed based on the concept of osseointegration of titanium, as claimed by Brånemark. The high success rate of implants and good long-term prognosis are influenced by patient factors and the condition of the implant. Patient factors were not the topic of this study; the study focused instead on the conditions of the implants. Implant conditions include physical properties, surface treatments, corrosion resistance, abrasion resistance, and others. The condition of the implant surface that directly integrates with the bone is an essential factor. This implant condition is actively studied to enlarge the contact area between the bone and the implant and to increase the removal torque using surface treatments. Acid treatment methods using hydrochloric, sulfuric, and hydrofluoric acids have been introduced, which produce micropits with a diameter of 0.5 2.0 μm on the implant surface. These acidtreated surfaces increase the apposition of bone on the implant surface by enhancing the osteogenic mechanism through the attachment of fibrin and osteoblasts. Studies have determined that the implant surface treated with blasting and acid etching (SLA) results in a high BIC, high osseointegration strength, and high clinical success rates. The acid treatment used for Straumann SLA implants is the dualhttps://doi.org/10.4047/jkap.2019. 57.4. 335 ORIGINAL ARTICLE
Study on the Policy Effect of Beijing-Tianjin Industrial Transfer on the Development of Hebei—Based on Empirical Analysis of Regression Discontinuity

Based on the panel data of Beijing, Tianjin and Hebei from 2004 to 2016 and the obvious changes of the industrial transfer caused by the policy coordinating development of Beijing-Tianjin-Hebei as a national strategy in 2014, this paper makes a regression discontinuity on the exogenous impact of the policy on the development in Hebei. The results show that: Firstly, in 2015, the amount of industrial transfer from Beijing-Tianjin to Hebei has increased nearly three times than that of 2014. Secondly, the contribution rates of the policy to the increase of per capital gross regional product and rural per capita net income are 47.8% and 62.3% respectively. Thirdly, the policy has different effects on different regions, the central and eastern areas of Hebei are the most policy-sensitive which made the Theil of these areas fall by 0.1%.
Condicionantes ecológicos, costes y beneficios asociados a la colonialidad en el Cernícalo Primilla: Resumen

ENTRE 1993 Y 1996 SE ESTUDIARON LOS FACTORES QUE PUEDEN CONDUCIR A LA COLONIALIDAD EN EL CERNICALO PRIMILLA (FALCO NAUMANNI), ASI COMO LOS POSIBLES COSTES Y BENEFICIOS DE LA MISMA.

Modeling Radar Albedos of Laboratory‐Characterized Particles: Application to the Lunar Surface

We analyze lunar images obtained by the Mini Radio Frequency instrument onboard the Lunar Reconnaissance Orbiter to interpret the anomalous radar scattering observed in some lunar craters. We compare the radar signatures of the crater floors to those of the regions external to the crater rim and show that there is a systematic difference between the radar albedo trends of the two regions. Using numerical simulations to compute radar scattering properties of rock and ice particles, we demonstrate that the difference is caused partly by the near‐surface bulk volume density or the underlying fine‐grained regolith and partly by the shape and size distributions of centimeter‐to‐decimeter‐scale rubble. We show that while the size distribution of wavelength‐scale particles plays the major role in the observed radar albedos, if the size distribution is fixed, the particle shapes can play a greater role than the composition; therefore, the icy material is indistinguishable from silicate‐rich material unless the abundance of ice in the particles plays a major role in the shape of the particles.
Seismicity around Sunda strait and its surroundings based on hypocenter relocation using 3-D velocity: a preliminary result of relocated hypocenter database construction from the BMKG catalog

The relocated hypocenters are very important to study advanced tectonic in one area. The Indonesian Agency for Meteorology, Climatology, and Geophysics (BMKG) provides a complete earthquake catalog consisting of hypocenter parameter and seismic wave arrival times of P and S phases or only P phase in every seismic station. This study uses the BMKG earthquake catalog from April 2009 to December 2018, in which the earthquakes were recorded by BMKG and international seismic networks. The hypocenters from the BMKG catalog are relocated using a 3-D regional velocity model and applying the teletomoDD method for hypocenter relocation. The results succeed in detecting many tectonic features in Indonesia. The study result will be useful to provide a precise hypocenter for earth scientists around the world who is interesting in a tectonic study in Indonesia. Some tectonic features which are interesting exist in Sunda Strait and its surrounding. The complex structure in Sunda Strait causes the area having high seismic activities. The results show seismic activities in three regions are delineated well. The first seismic region relates to the subduction zone. There is low seismic activity in the Wadati-Benioff zone from 70-120 km. This result is a little different from the previous study. The different result is most likely caused by the use of data and methods that are not the same. The second seismic region associates with graben fault. The last or third seismic region exists beneath Anak Krakatau Volcano relating to the magmatic activity. The last two seismic regions are detected clearly because there are no more fix depths at a depth 10 km after hypocenter relocation.
A Comprehensive Review of Faith-Based Physical Activity Interventions

This review provides a summary of physical activity interventions delivered in faith-based organizations. Electronic databases were searched to identify relevant studies. After screening, a total of n = 27 articles matched our inclusion criteria; 19 were identified as faith-based interventions (some spiritual or Biblical element included in the intervention) and 8 as faith-placed interventions (no spiritual component). Among all interventions, the most common research design was a randomized controlled trial. African American women were the most commonly targeted population and predominately Black churches were the most common setting. The majority of studies used self-report measures of physical activity. Most of the interventions did not use a theoretical framework to shape the intervention and weekly group sessions were the most frequently reported intervention approach. Overall, 12 of the faith-based and 4 of the faith-placed interventions resulted in increases in physical activity. Recommendations for future faith-based physical activity interventions include more rigorous study design, improved measures of physical activity, larger sample sizes, longer study and follow-up periods, and the use of theory in design and evaluation. Although limited, literature on faith-based physical activity interventions shows significant promise for improving physical activity participation and associated health outcomes.
The Role of Zonally Averaged Climate Change in Contributing to Intermodel Spread in CMIP5 Predicted Local Precipitation Changes

While CMIP5 models robustly project drying of the subtropics and more precipitation in the tropics and subpolar latitudes by the end of the century, the magnitude of these changes in precipitation varies widely across models: for example, some models simulate no drying in the eastern Mediterranean while others simulate more than a 50% reduction in precipitation relative to the model-simulated present-day value. Furthermore, the factors leading to changes in local subtropical precipitation remain unclear. The importance of zonal-mean changes in atmospheric structure for local precipitation changes is explored in 42 CMIP5 models. It is found that up to half of the local intermodel spread over the Mediterranean, northern Mexico, East Asia, southern Africa, southern Australia, and southern South America is related to the intermodel spread in large-scale processes such as the magnitude of globally averaged surface temperature increases, Hadley cell widening, polar amplification, stabilization of the tropical upper troposphere, or changes in the polar stratosphere. Globally averaged surface temperature increases account for intermodel spread in land subtropical drying in the Southern Hemisphere but are not important for land drying adjacent to the Mediterranean. The factors associated with drying over the eastern Mediterranean and western Mediterranean differ, with stabilization of the tropical upper troposphere being a crucial factor for the former only. Differences in precipitation between the western and eastern Mediterranean are also evident on interannual time scales. In contrast, the global factors examined here are unimportant over most of the United States, and more generally over the interior of continents. Much of the rest of the spread can be explained by variations in local relative humidity, a proxy also for zonally asymmetric circulation and thermodynamic changes.
Unidirectional continuous fiber-reinforced polypropylene single-polymer composites prepared by extrusion–calendering process

An extrusion–calendering process was developed to continuously manufacture unidirectional continuous fiber-reinforced polypropylene single-polymer composites (PP SPCs). The process combined “undercooling” property of the matrix and “overheating” property of the fiber, which can not only establish a wide processing temperature window but also enhance the mechanical properties of the final SPCs. The best tensile strength and modulus of the PP SPCs with only 5 wt% fiber content were up to 53.34 ± 3.56 MPa and 1.81 ± 0.14 GPa, 2 times and 1.59 times higher than those of pure PP, respectively, and they also exceeded the theoretical values due to the high performance of the uniaxial fibers and the optimized process. The influences of the die temperature, fiber contents, and fiber distribution were studied. Scanning electron microscopy was also used to observe the morphological properties of the PP SPCs.
agomelatine in the treatment of depressive disorders in clinical practice: multicenter observational chrONOs study

Background: CHRONOS was a large naturalistic study designed to evaluate the effectiveness and safety of agomelatine in the management of patients with major depression in routine clinical practice. Methods: Patients (n = 6,276) with a moderate or severe major depressive episode without psychotic symptoms were treated initially as outpatients (80.2%) or in psychiatric facilities (19.8%) in 54 regions of the Russian Federation. Patients received a flexible-dosing regimen of agomelatine 25 mg or 50 mg once daily for 8 weeks, with frequent study visits (weeks 1, 2, 3, 4, 6, and 8). Results: Patients (mean age 44 years, 72.6% female) showed progressive improvement on the 17-item Hamilton Rating Scale for Depression (HAMD-17) total score from 22 ± 6.9 at baseline to 4.7 ± 4.7 at week 8 ( P , 0.0001). The proportion of responders (HAMD-17 decrease of $ 50%) was 90.1% and the proportion of remitters (HAMD-17 , 7) was 79.1% at week 8. All individual HAMD-17 item scores improved rapidly, and the change relative to baseline was significant ( P , 0.0001) at week 1 and at each subsequent visit in all cases. There were corresponding rapid improvements in Clinical Global Impression Severity and Improvement scores. In the subgroup of patients with more severe illness (HAMD-17 $ 21 at baseline; n = 3,478), the proportions of responders and remitters were 92.4% and 72.8%, respectively, at week 8. Conclusion: Agomelatine was effective and well tolerated in a large sample of depressed patients in an observational treatment setting, and showed a rapid onset of benefit across all HAMD-17 items.
The Effect of Temperature and Twist Ratio from Twisted Tape Insert to Pumping Power in Concentric Exchange Tools using Nanofluida TiO2 and Oli Termo XT-32

The heat exchanger is a device used to heat between two or more fluids. Heat exchangers can use fluid flow or construction. Heat exchangers are widely used in engineering applications. The heat exchanger has long been recognized by industries that relate to heat transmission phenomena. Improve the speed of all types of heat exchangers widely in the industry, in the process of retrieval (heat recovery process), air conditioning, and chemical reactors. Increasing the amount of light flow can be done in several ways, namely: flowing inequality, damaging the boundary layer, changing the fluid flow, and rotating fluid flow (vortex flow). One of the techniques used to increase the heat coefficient of convection is to provide insert material or often called Insert. The research methodology was to determine the effect of the rotational ratio of the insertion bent band on the pumping power of the pipe heat exchanger by using TiO2 nanofluid with a heat transfer oil base fluid (thermo XT32). This research was carried out with experimental methods, as for the tools and research materials in this case: primary fluid of thermo XT32, TiO2 nanoparticles, and an annular channel concentric pipe heat exchanger by inserting a bent band. In and out data (Th, i and Th, o), the temperature of the fluid in and out of the annulus (Tc, i and Tc, o), the outer wall temperature of the inner tube (Tw1, Tw2, Tw3, Tw4), and the water height difference on the manometer. Data collection was carried out with TiO2 particle nano samples with a volume fraction of 0.3% Vol, without a bent band. Insert (plain tube) and rotate the tape with a touch ratio of 3, 6, and 9. The results of the research carried out on the conclusion of the rotational ratio in the band bending the insertion of the pumping power of the heat exchanger. This proved the pumping power increases with decreasing rotational ratio from a bent band, the addition of a twisted tape insert can increase the pumping power when compared to a pipe heat exchanger without concentrically turning the inserted tape (plain tube), this is proven by using a twisted tape insert with a twist ratio of 3. It requires a pumping power of 87.71 W / m2 to be able to drain TiO2 nanofluid, with a volume fraction of 0.3% Vol at a fluid temperature of 60 °C whereas when compared to a heat exchanger without turning the inserted tape (plain tube), it only requires pumping power of 17.73 W / m2. to be able to drain nanofluid in a heat exchanger.
Enhancing the Charge Extraction and Stability of Perovskite Solar Cells Using Strontium Titanate (SrTiO3) Electron Transport Layer

Charge transport layers strongly influence the performance of perovskite solar cells (PSCs). To date, compact layers and mesoporous scaffolds of titanium dioxide have emerged as good electron transport layers (ETL), enabling record power conversion efficiencies (PCE). However, these ETLs require sintering above 400 °C, which excludes them from low-temperature applications such as flexible devices and silicon-heterojunction tandems. Furthermore, instability of TiO2 under prolonged exposure to sunlight appears to be a critical issue. Here, we present the promising characteristics of low-temperature processed strontium titanate (STO) as an ETL to realize PSCs with 19% PCE. STO is a wide bandgap transparent inorganic perovskite. Compared with other low-temperature processed interlayers, STO reduces the parasitic absorption in the ultraviolet and visible range, improves the electron transport, and greatly increases the stability of the devices, retaining ∼80% of their initial efficiency after 1000 h of constan.
Adherent diamond coating deposited on Ti by ultrasonic after carbonization pretreatment

The adhesion of wear-resistant diamond coating deposited on titanium was weakened by the porous titanium carbide interlayer, which was formed before film growth. In order to enhance substrate-coating adherence, a new pretreatment method was presented: Ti substrates were carbonized by hot filament chemical vapor deposition system, and then the carbonized substrates were ultrasonically vibrated using diamond micro-powder suspension. Diamond coatings were deposited by hot filament chemical vapor deposition as well. The effect of carbonization time on adhesion was investigated. The carbonized substrates and the interface between diamond coatings and substrates were characterized. The results showed that as the carbonization time increases, porous structures and cracks appear and increase on the surface of the substrate. The carbonized substrates possess high surface energy and thus the nucleation is promoted. After deposition, a dense and thin titanium carbide was observed. Ultrasonic after carbonization pretreatment can significantly enhance the adhesion of Ti-based diamond coatings by promoting nucleation and suppressing the formation of porous titanium carbide.
Raman-based study of micro/nanoscale structure and thermal transport

Nanoparticles, two-dimensional (2D) materials, and carbon fibers are widely used in nano electronic devices, aerospace structures due to their extraordinary properties. Among these properties, the surface morphology and the thermal transport are two important properties. The Raman scanning technique is used to characterize the surface morphology. But, the various asymmetries of Raman scattering due to structure variation in space are not considered. The optothermal method based on Raman spectroscopy is widely used to study the thermal transport of these materials. However, a significant drawback of this method is that both temperature and power dependent Raman study should be done to extract the thermal conductivity of the sample. The laser absorption is also subject to very large errors induced by unknown sample-to-sample optical property variation. In addition, for measuring the thermal conductivity of carbon fibers, it is very important to verify whether the thermal conductivities in axial and radial directions are isotropic. In this work, a Raman scanning technique is developed to explore the asymmetry of Raman scattering signal caused by structure variation in space. A nanosecond energy transport state-resolved Raman (ns ET-Raman) technique is developed to measure the thermal conductivity of suspended 2D atomic-layer molybdenum disulfide (MoS2) and molybdenum diselenide (MoSe2). And a novel method by combining the frequency domain energy transport state-resolved Raman (FET-Raman) technique and the transient electrothermal (TET) technique is developed to measure the anisotropic thermal conductivities of lignin-based microscale carbon fibers. The Raman scanning technique combines the confocal Raman system with a three-dimensional (3D) scanning stage. Silica
Preparation and tribological properties of a kind of lubricant containing cerium borate nanoparticles as additives

Oil-soluble compounds containing boron as lubricating additives were restricted by the hydrolysis of borate ester. In order to overcome this problem, cerium borate nanoparticles modified with oleic acid (O-CeB) as a potential substitute for conventional lubricant additive were studied in detail. The microstructures of the prepared nanoparticles were characterized. Tribological properties of cerium borate nanoparticles used as additive in base oil were evaluated, and the worn surface of the steel ball was investigated. The results show that O-CeB possesses better anti-wear ability at relatively higher concentration; in particular, it shows better friction-reducing ability under all these studied concentrations. Under higher load, its anti-wear property and friction-reducing property are better than that of Vanlube 289 in the base oil. Based on these results of interferometric surface profilometer and X-ray photoelectron spectroscopy, it can be deduced that a continuous resistance film containing depositions and the tribochemical reaction products was formed during the sliding process.
The Permeability of Columnar Jointed Lava

Columnar jointed lava is an important facies in many geothermal reservoir systems. The permeability of jointed lavas is dominated by the contribution from fracture networks. We use a scaling for the permeability of a set of fractures in a solid or porous mass and extend this to arrays of hexagonal intercolumn fractures. To validate our analytical results, we create numerical domains with relevant geometries and extract system‐scale permeability using the LBflow lattice‐Boltzmann fluid flow simulation tool. Finally, we model the cooling contraction of columns to extend our results so that they predict the permeability with time after lava emplacement. Importantly, we use these results to estimate the range of permeabilities typical of columnar joints that form during cooling from high temperature and are preserved in the crust at moderate to low temperatures.
Precipitation δ18O Recorded by the α‐Cellulose δ18O of Plant Residues in Surface Soils: Evidence From a Broad Environmental Gradient in Inland China

In order to determine the potential of α‐cellulose δ18O (δ18Ocell) data from multiple terrestrial plant species on an ecosystem level to record the δ18O data of precipitation (δ18Op), especially in relatively cold and arid environments, we collected samples of terrestrial plant residues from 104 surface soils covering a large environmental gradient (~29 to 51°N in latitude, ~81 to 124°E in longitude, ~200 to 5,100 m in elevation) in inland China. Despite the diverse vegetation types, wide range of climatic conditions and potentially complex biogeochemical processes operating within the vast study region, the δ18Ocell data show a similar spatial pattern to that of δ18Op. The results demonstrate that the measured values of δ18Ocell data have the potential to record variations in δ18Op. Further analysis indicated that the δ18Ocell data from the Tibetan Plateau were primarily controlled by the moisture sources. Interestingly, there are significant negative correlations between δ18Ocell/δ18Op and altitude on the Tibetan Plateau, implying the potential of δ18Ocell for paleoaltimetry in this region. The δ18Ocell data from the northern region of China (including the East Asian monsoon‐margin and arid central Asia) were mainly controlled by temperature, although the influence of relative humidity in the region is not negligible. Our results provide a fundamental reference for related δ18Ocell studies aimed to improve our understanding of environmental, hydrological, and climatic changes in inland China and elsewhere.
