Screw- vs. Cement-retained Implant-supported Prosthesis in Partially Edentulous Patients

Understanding the morbidity events, incidence, and cost associated with each type of retention system used for implant supported prosthesis will help the clinician in better decision making. This study assessed the clinical and cost-effectiveness of the screw- and cement-retained implant-supported single crown and fixed partial denture for the replacement of teeth in partially edentulous jaws, from a health services perspective. A systematic literature search conducted in 10 databases, complemented by 4 journal databases and International Association for Dental Research abstracts, identified 92 studies on the single crown and 40 studies on the fixed partial denture. Minor and major technical complication events, as well as failure events, were extracted from strong- and medium-quality studies. Studies based on similar designs were pooled with a random-effects Poisson regression model. A decision tree was developed to estimate the cost-effectiveness over a 15-y period posttreatment. The initial and maintenance costs to treat technical complication events were based on an American Dental Association survey of 2011 to 2012. Probabilistic sensitivity analysis was used to examine the uncertainty in the data input parameters. Clinical evidence generated from the meta-analysis suggested no statistical difference between the 2 retention systems. The cost-effectiveness is presented as an incremental cost-effectiveness ratio. The evidence from this report suggests that cement retention is the more cost-effective strategy as compared with screw retention prosthesis. Knowledge Transfer Statement: Evidence generated by this study will help clinicians make an appropriate cost-effective treatment decision in choosing the retention system for partially edentulous patients.
Path Length Correction for Improving Leaf Area Index Measurements Over Sloping Terrains: A Deep Analysis Through Computer Simulation

The in situ measurement of the leaf area index (LAI) from gap fraction is often affected by terrain slope. Path length correction (PLC) is commonly used to mitigate the topographic effect on the LAI measurements. However, the terrain-induced uncertainty and the accuracy improvement of the PLC for LAI measurements have not been systematically analyzed, hindering the establishment of an appropriate protocol for LAI measurements over mountainous regions. In this article, the above knowledge gap was filled using a computer simulation framework, which enables the estimated LAI before and after PLC to be benchmarked against the known and precise model truth. The simulation was achieved by using CANOPIX software and a dedicatedly designed ray-tracing method for continuous and discrete canopies, respectively. Simulations show that the slope distorts the angular pattern of the gap fraction, i.e., increasing the gap fraction in the down-slope direction and reducing it in the up-slope direction. The horizontally equivalent hemispheric gap fraction from the PLC can reconstruct the azimuthally symmetric angular pattern of the real horizontal surface. The azimuthally averaged gap fraction for sloping terrain can both be underestimated or overestimated depending on the LAI and can be successfully corrected through PLC. The topography-induced uncertainty in LAI measurements is found to be ~14.3% and >20% for continuous and discrete canopies, respectively. This uncertainty can be, respectively, reduced to ~1.8% and <7.3% after PLC, meeting the up-to-date uncertainty threshold of 15% established by the Global Climate Observing System (GCOS). Closer analysis shows that the topographic effect is influenced by fractional crown cover, and the largest uncertainty which corresponds to extensively clumping canopy can reach nearly up to 50%. The accuracy of the estimated LAI after PLC safely meets the GCOS uncertainty threshold even for this extreme case. This study demonstrates the necessity of a topographic correction for LAI measurements and the applicability of PLC for reconstructing the horizontally equivalent gap fraction and improving the LAI measurements over sloping terrains. The results of this article throw light on the design of a protocol for LAI measurements over mountainous regions.
Effect of Composition of Iron-Cobalt Oxide Catalyst and Process Parameters on The Hydrothermal Liquefaction of Sugarcane Bagasse

Development of catalyst with high deoxygenation activity and optimum process parameters are the key for getting the highest biooil yield with the least oxygen content by hydrothermal liquefaction. With this view, iron-cobalt oxides of Co/Fe ratio 0.33, 1.09, 2.35, and 3.52 were prepared by co-precipitation method, and characterized by XRD, BET surface area, chemical composition by EDX method, and evaluated for hydrothermal liquefaction of sugarcane bagasse in a high-pressure batch reactor under subcritical conditions using CO as process gas to find the optimum Co/Fe ratio and process parameters. Optimum Co/Fe ratio was found to be 1.09 as it gave the highest bio-oil yield of 57.6% with the least oxygen content of 10.8%, attributed to the cobalt ferrite, the major phase present in it. The optimum temperature, initial CO pressure, water/biomass ratio, catalyst/biomass ratio and reaction time for the highest oil yield with the least oxygen content were found to be 250 °C, 45 bar, 28, 0.4, and 120 min, respectively. From the effect of reaction time, it was found that much of the hydrolysis of lignocellulose to water soluble oxygenates, its deoxygenation to bio-oil and its deoxygenation to low oxygen containing bio-oil took place in initial 15 min, 15 to 60 min, and from 30 to 120 min, respectively. Total oil yield (%) was lower by 21% and % oxygen in total oil was higher by 9.9% for spent catalyst compared to fresh catalyst indicating the erosion in the deoxygenation activity of catalyst and thus need for improving its hydrothermal stability.

Viral Hepatitis B: Seroprevalence and Genetic Diversity in Blood Donors North of Congo

Introduction: Viral hepatitis B is the most formidable and confusing of all viral hepatitis, given its cirrhogenic and carcinogenic potential. The objective of the study is to characterize the molecular profile of hepatitis virus B in northern Congo. Materials and Methods: This was a descriptive and cross-sectional study that was carried out between January and September 2014, that is 9 months, in the establishments of the National Center for Blood Transfusion (CNTS) of the 4 departments of the north of the Congo. Epidemiological, serological and molecular variables (HBsAg, HBV DNA, genotypes and subtypes) were studied. The HBs antigen was searched by rapid test and confirmed by ELISA. For all positive donors, conventional and specific gene extraction and amplification techniques were performed for the identification of genotypes and subtypes from the serum. Results: A total of 892 donors were included. The average age was 35.36 ± 12.36 years with extremes ranging from 18 to 65 years old. The sex ratio (M/F) was 3.3. The prevalence of HBV was 8.6%. The viral DNA of HBV was amplified in 83.1%. Four genotypes were found: E (40.6%), A (3.1%), B (3.1%) and C (1.6%). Two cases of co-infection were identified: E/A (15.6%) and B/C (1.6%). Subgenotypes A1, B2 and C1 were highlighted. Conclusion: The prevalence of HBV is high, HBV infection remains a major public health problem for blood donors in Congo. Genotypes E, A, B, C as well as subtypes A1, B2, C1 have been identified in northern Congo.
Analysis of Critical Thinking Ability of Sixth-Grade Students Primary School

This research is motivated by the importance of critical thinking skills in 21stcentury education. The purpose of this study is to determine the critical thinking skills of elementary school students and the factors that can influence it in Sukoharjo 02 Elementary School, Sukoharjo Regency. This study included descriptive qualitative research. The subjects of this study were class VI students who were selected by purposive sampling technique. Data collection is done through observation, interviews, and tests. Data analysis is done by flow analysis. Based on the results of research and discussion, information obtained from 6 of 28 students or about 21% of students whose grades can reach 70, the minimum completeness value 70. The average score of all students is 52. It shows that the students' ability to think critically is still low. Based on several indicators of critical thinking shows the average value of students answering interpretation questions, namely 46.43, analysis of 50.89, inference 65.18, and explanation 45.54. The low average value is caused by several factors, namely: students answer with short answers so the answers become incorrect, there are students’ misconceptions because students' understanding from the beginning is wrong, and the most often done by the students is to answer systematically.
Selecting for Chlamydomonas reinhardtii fitness in a liquid algal growth system compatible with the International Space Station Veggie plant growth chamber

A biological life support system for spaceflight would capture carbon dioxide waste produced by living and working in space to generate useful organic compounds. Photosynthesis is the primary mechanism to fix carbon into organic molecules. Microalgae are highly efficient at converting light, water, and carbon dioxide into biomass, particularly under limiting, artificial light conditions that are a necessity in space photosynthetic production. Although there is great promise in developing algae for chemical or food production in space, most spaceflight algae growth studies have been conducted on solid agar-media to avoid handling liquids in microgravity. Here we report that breathable plastic tissue culture bags can support robust growth of Chlamydomonas reinhardtii in the Veggie plant growth chamber, which is used on the International Space Station to grow terrestrial plants. Live cultures can be stored for at least one month in the bags at room temperature. The gene set required for growth in these photobioreactors was tested through a short-wave ultraviolet light (UVC) mutagenesis and selection experiment with wild-type (CC-5082) and cw15 mutant (CC-1883) strains. Genome sequencing identified UVC-induced mutations, which were enriched for transversions and nonsynonymous mutations relative to natural variants among laboratory strains. Genes with mutations indicating positive selection were enriched for information processing genes related to DNA repair, RNA processing, translation, cytoskeletal motors, kinases, and ABC transporters. These data suggest modification of signal transduction and metabolite transport may be needed to improve growth rates in this spaceflight production system.

Results of closed reduction percutaneous screw fixation and open reduction internal fixation in tibial plateau fractures

Background: Tibial plateau fractures are common injuries that require anatomic reduction to obtain the best functional results. Advance in mechanization and acceleration of travel has been accompanied by an increase in number and severity of fractures and those of the tibial plateau are not an exception. This fracture constitutes approximately 1% of all fractures. Open reduction and rigid internal fixation for displaced tibial plateau fracture achieves the goals of restoring the anatomic articular congruity and mechanical alignment, while allowing early knee mobilization. Aims and Objectives: To study the results and complications of open reduction and internal fixation by plate osteosynthesis versus closed reduction and percutaneous cannulated screw fixation for tibial plateau fractures. Method: 43 patients with tibial plateau fractures treated either with open reduction and plate osteosynthesis or closed reduction and percutaneous cannulated screw fixation were followed up for a period of 18 months and their functional outcome was assessed according to Modified Delamarter functional scoring system. Results: According to modified Delamater functional score, 90% had excellent to satisfactory result in patients treated with percutaneous screw fixation as compared to 67% in those treated with open reduction internal fixation. In both modalities 9% had poor results due to nonunion. Conclusion: Closed reduction and percutaneous screw fixation for tibial plateau fractures is minimally invasive. It reduces the length of hospital stay and costs, enables early mobilization with minimal instrumentation, and achieves satisfactory outcome as compared to open reduction and plate fixation.
Reorienting Spatial Attention within Visual Working Memory

Attention and working memory (WM) are intertwined core cognitive processes. Through four experiments with 133 participants, we dissociated the impact of two types of covert spatial attention, endogenous vs. exogenous, on visual WM. Behavioral results consistently indicated that exogenous attentional cues were more advantageous than endogenous ones in enhancing the precision of visual WM under load-2, while they equalized under load-4. In addition, physiological and neural data explained the mechanisms. Converging evidence from eye-tracking, electroencephalography, and magnetoencephalography suggested that fast attentional processing induced by exogenous cues lead to early top-down information from the dorsal lateral prefrontal cortex (DLPFC) to sensory cortices. The differential frontal activities were further correlated with the behavioral distinctions between exogenous and endogenous cues, and transcranial magnetic stimulation over DLPFC at the same time period abolished the exogenous advantage. Taken together, traditionally considered bottom-up attentional processing induced by exogenous cues rapidly engages top-down signals from the frontal cortex, which leads to stronger behavioral benefits compared with the benefits produced by endogenous cues under the low load condition.
Tribocorrosion behaviour of porous anatase and rutile phases formed on surface of anodised Ti45Nb alloy

Titanium alloys are used across a wide range of sectors—from aerospace to health—because of their low density, high strength, and corrosion resistance properties. In recent years, the use of alloying elements such as niobium (Nb), tantalum (Ta), and zirconium (Zr) has still not eliminated existing wear problems, in spite of being preferred to conventional titanium alloys that are non‐toxic and have better corrosion and mechanical properties. In order to overcome this problem of titanium alloys, various surface treatments are applied. This study was mainly aimed at investigating tribocorrosion properties of anatase, rutile, and anatase‐rutile phases formed on the surface of Ti45Nb by anodising at different potential values. The structural and mechanical properties of these structures were examined by X‐ray diffraction (XRD), scanning electron microscopy (SEM), energy‐dispersive spectroscopy (EDS), nanoindentation, and a 3D profilometer. Tribocorrosion tests were carried out at open‐circuit potential (OCP) and two different anodic in NaCl solutions. It was found that the wear volume was affected by mechanical action rather than chemical effects for all samples during tribocorrosion. It was concluded that while a surface structure including anatase is more sensitive to chemical effects, the rutile structures were shown to be more resistant to both mechanical and chemical attacks during tribocorrosion tests.
A search for the Standard Model Higgs boson produced in association with dileptonically decaying top quarks and decaying into a pair of bottom quarks with the ATLAS detector

A search for the Standard Model Higgs boson produced in association with a pair of top quarks, where the Higgs boson decays to a pair of bottom quarks, is presented. The search uses 36.1 fb−1 of p-p collision data at a centre-of-mass energy of √ s = 13 TeV collected using the ATLAS detector at the Large Hadron Collider in 2015 and 2016. Focus is placed on the search for the final state where decays of both top quarks produce charged leptons, referred to as the dileptonic final state. The development and study of the statistical fit used to measure the presence of collision events containing Higgs bosons is presented. Results from the combination of the search for the dileptonic final state with the search for the related single-lepton final state are presented. This combined search measured a signal cross-section of μ = 0.84+0.64 −0.61 times the Standard Model expectation. This result was later combined with searches for final states containing other Higgs boson decays to produce an observation of the production of the Standard Model Higgs boson in association with a pair of top quarks. Developments to the portion of the ATLAS trigger system responsible for track reconstruction are also presented.
Asymptomatic Ocular Changes among Long Term Contact Lens Users

The purpose of this was to determine asymptomatic adverse ocular changes among long term contact lens users. It was a cross-sectional study and convenient sampling was used to collect the sample of 100 contact lens users. This study was conducted in 4 months from 05-04-2016 to 05-08-2016 and sample was recruited from Madinah Teaching Hospital Faisalabad, E Plomer Optics and Punjab Optics Lahore. Tear film break up time (TBUT) and corneal changes were determined by using slit lamp and blink rate was recorded by direct observation and counting. SPSS version 23 was used for data analysis. Descriptive statistics was reported for variables. Results showed that 67% of contact lens users were females, 54% used soft contact lenses and 96% were myopic. Mean age of contact lens users was 30.10 ± 7.86 years. Mean daily wearing time of contact lenses was 9.82 ± 2.19 hours/day. Mean value of years of contact lens use was 8.35 ± 5.81 years. Normal range of blink rate was present in only 6 % of subjects and mean value was 26.14±6.94 blinks/minutes. 67% of subjects had abnormal TBUT and mean value was 9.14±2.89 sec. 58% of contact lens users were presented with one or more corneal changes. It was concluded that u n-monitored, long term use of contact lenses caused many adverse ocular changes among asymptomatic contact lens users. So regular follow-up exams are necessary for contact lens users to maintain good ocular health.
Does earning management mediate the effect of capital structure on company value?

This study aims to examine the effect of capital structure on company value with earnings management as a mediating variable. The capital structure is proxied using a debt to equity ratio (DER), company value is proxied using Tobin’s Q and real earnings management is proxied using costs of production activities. The research population is 144 manufacturing companies listed on the Indonesia Stock Exchange (IDX). 204 samples are used in this study. Data used in this study is the secondary data obtained from Indonesia Stock Exchange, contained on www.idx. co.id. The data analysis method used in this study is partial least squares (PLS) method using a WarpPLS 4.0 application. The results of the analysis show that capital structure has a positive effect on company value and real earnings management is proven to partially mediate the effect of capital structure on company value. The results of this study should encourage standard-setting bodies to make stricter regulations on real earnings management practices that tend to cause management to commit fraud.
The influence of Widmanstätten ferrite , martensite and grain boundary carbides on the strength and impact behaviour of high Al ( 0 . 2 % ) and Nb containing hot rolled steels

The influence of Al and Nb on the strength and impact behaviour of hot rolled 0.06%C, 1.4%Mn steels has been determined after hot rolling to 15 and 30mm thick plate. When 0.16%Al was added to the plain C-Mn steel, the impact behaviour significantly improved even though Widmanstätten ferrite (WF) was present. This improvement was due to refinement of the grain boundary carbides and removing the N from solution as AlN. The hot rolled steels all contained WF but when Nb was added more WF formed as well as MA giving poor impact behaviour. Reducing the hardenability from that shown in previous work by decreasing C from 0.1 to 0.06%, Nb from 0.03 to 0.02%, and cooling rate from 33 to 17K/min had no effect in improving the impact performance of hot rolled Nb steels. To ensure optimum properties not only is it necessary to reduce the hardenability, but WF formation must be discouraged by having a high Ar3. This can only be presently achieved by refining the austenite grain size via control rolling the Nb containing steels; the benefit of adding Al can then, readily be seen. Suggestions are made as to how this might be achieved for hot rolling.
Complexity in the beautiful game: implications for football research and practice

ABSTRACT Like many other sports, football is increasingly being described as a complex system. To date, however, there has been little explanation of complexity beyond the team level, and no formal examination of the extent to which the known characteristics of complex systems are present in football. This commentary reviews known characteristics of complex systems and discusses the extent to which football match, club, and league sub-systems exhibit them. It is argued that all three football sub-systems do indeed exhibit the characteristics of complexity, and as such, it is concluded that football can be described as a complex system. The implications for future football research and practice are discussed. Applications of complex systems modelling techniques are encouraged, both to model football systems and to identify how different systemic variables interact to influence performance. A paradigm shift away from reductionism toward holism in football research is advocated.
