Fissure sealants in caries prevention : a practice-based study using survival analysis

The purpose of this study was to analyse the effectiveness and cost of fissure sealant treatment in preventing dental caries in children in a practice-based research network using survival analysis. The survival times of first permanent molars in children were analysed in three countries: in Finland (age cohorts 1970–1972 and 1980–1982), in Sweden (1980–1982) and in Greece (1980–1982), and additionally at two municipal health centres in Finland (age cohorts 1988–1990 in Kemi and 1990 in Vantaa). The study population comprised altogether 8 551 children. The data were collected manually from paper dental records (Finland, Sweden and Greece), and an automatic data-mining system for collecting data from electronic dental records was used in the case of the two health centres in Finland (Kemi and Vantaa). Comparisons of the survival times of first molars caries-free were performed between sealed and non-sealed individual teeth, and between the subjects in cases where a subject’s all first permanent molars were either sealed or non-sealed before the age of eight years. The cumulative costs of caries risk determination, use of xylitol, fissure sealant treatment, and restorations were calculated based on the data from the digital dental records of the health centres of Kemi and Vantaa. The results stressed the importance of caries-risk assessment on a tooth and subject level, when estimating the need for sealing treatment. Sealing of first molars of very high caries risk children (caries present in any of the permanent first molars before the age of eight years) seemed to be insufficient to prevent further dental decay later on. Instead, sealants were beneficial in caries prevention in medium-risk children (caries present in any of the permanent first molars between the ages of eight and ten years). Low-risk children (no caries in any of the permanent first molars before the age of ten years) did not benefit remarkably from sealant treatment. When sealant treatment were targeted only at high caries risk children based on risk-determination at the age of two years and all their permanent first molars were sealed (Kemi), their total treatment costs later were higher compared to the low-risk children, who were left unsealed. Significant differences in the survival curves of sealed and non-sealed first molars on a tooth and subject level confirmed that a translational approach is needed to study the effectiveness of preventive dental treatment in practice. The practice-based study model provides a good overview on the situation in real-life circumstances and helps to incorporate the evidence-based dentistry study results into everyday dental practice.
Extracellular β-D-fructofuranosidase from Aspergillus parasiticus: Optimization of the production under submerged fermentation and biochemical characterization

The β-D-fructofuranosidases are enzymes with biotechnological potential that can be used in different industrial sectors as food and beverage. In this context, microorganisms are important producers of these biomolecules, especially filamentous fungi. The production of extracellular β-Dfructofuranosidase from Aspergillus parasiticus using sugarcane bagasse as a carbon source under submerged fermentation was optimized by factorial design and high levels of enzyme were obtained in 24 h-old cultures at 30°C using 1.5% sugarcane bagasse under agitation. The extracellular β-Dfructofuranosidase was purified 119-fold using diethyl aminoethyl (DEAE)-cellulose and Sephacryl S-200 chromatographic columns with recovery of 16%. The native molecular mass was estimated as 136 kDa with two subunits of 63 kDa determined by 7% sodium dodecyl sulfate poly-acrylamide gel electrophoresis (SDS-PAGE) and 64% carbohydrate content. The purified enzyme showed optimal temperature of activity from 38-56°C and optimum pH from 4.5 to 6.2 determined by experimental design (CCRD), with half-life of 25 min at 50°C. It was stable from pH 5.0-10.0. The extracellular enzyme activity was stimulated by Ba 2+ and Mg 2+ , and it was not affected by urea, silver and ethylenediaminetetraacetic acid (EDTA). The K 0.5 and V max values were 10 mM and 1565 U/mg of protein, and 19 mM and 1965 U/mg of protein for sucrose and raffinose, respectively.

Strain-Induced Band Profile of Stacked InAs/GaAs Quantum Dots

The strain distribution and band profile in triply stacked InAs/GaAs quantum dots with dot spacing of 0.0 - 6.0 nm was calculated. The continuum elasticity theory for strain distribution and 8-band k.p theory for band structure was used. The use of the k.p method to calculate band structure with and without including the effects of strain is reported. The calculated results show the importance of strain effect on the confinement potential of the band structure for triply stacked InAs/GaAs quantum dots. doi: 10.14456/WJST.2014. 18

Should Pollution Taxes Be Targeted at Income Redistribution?

This paper analyses optimal corrective taxation and optimal income redistribution. Under general utility functions, the Pigouvian pollution tax is higher if pollution damages disproportionally hurt the poor due to equity weighting of pollution damages. Moreover, optimal pollution taxes should be set below the Pigouvian tax if the poor spend a disproportionate fraction of their income on polluting goods. However, if preferences for commodities are of the Gorman (1961) polar form, optimal pollution taxes should follow the first-best rule for the Pigouvian corrective tax even if the government wants to redistribute income and the poor spend a disproportional part of their income on polluting goods. The often-used quasi-linear, CES and Stone-Geary utility functions all belong to the Gorman polar class. If preferences are Gorman polar, and if pollution taxes are not optimized, Pareto-improving green tax reforms exist that move the pollution tax closer to the Pigouvian tax. Simulations demonstrate that optimal corrective taxes should be Pigouvian if the demand for polluting goods is derived from a LES demand system, but deviate from the Pigouvian taxes if demand for polluting goods demand is derived from a PIGLOG demand system.
Out-of-plane Shear Strength of Steel Plate Concrete Walls Dependent on Bond Behavior

This paper investigates out-of-plane shear behaviour of composite walls of steel plates (SC walls) and suggests a strength model based on the limit analysis in the framework of the plasticity theory. For speedy and modular construction, SC walls are fabricated by double steel plates with welded shear studs on steel plates and are filled with concrete between double steel surface plates. Review on current design formulas proposed by JEAG 4618 requires further understanding of shear behaviour dependent on bond stress relying on studs and taking into account of difference between ordinary reinforced concrete members. To this end an arch action dependent on bond action by shear studs is experimentally investigated with consideration of effectiveness factors for compressive strength of concrete of direct strut for arch action are proposed. The contribution of tensile strength and compressive strength of concrete to the shear strength due to arch action in short shear span ratio is investigated by assuming fan-shaped compression fields involving a strut in case of single curvature and double curvature types. Series of experimental programs have been prepared for verification of proposed shear strength models with test results. The test results, including those from JEAG, show good agreements with the proposed formula.
Beauty and the Beast Toward a Measurement Framework for Quality of Example Programs

are important tools for programming education. In this paper, we investigate desirable properties of programming examples from a cognitive and a measurement point of view. We argue that some cognitive aspects of example programs are "caught" by common software measures, but they are not suffi- cient to measure understandability of examples. We conclude that a framework for measuring understandability of examples should also consider factors related to the usage of the example.
Variability patterns in Ugandan pigeonpea landraces

In-situ evaluation of pigeonpea cropping system and management in Uganda and agro-morphological characterization of 29 pigeonpea landraces were studied in 2001 and 2004/05, respectively. Results showed that pigeonpea in Uganda is predominantly intercropped with finger millet and to some extent with maize and sorghum. Farmers largely used saved grain as seed and appreciated the damage by insect pests, but only farmers in Apach and Lira districts practiced any form of pest control. Observations across the collection districts indicated low levels of Fusarium wilt disease. Agronomic evaluation of the 29 accessions revealed differential adaptation at the two test locations in Kenya with accessions expressing a delayed phenology at the cooler Kabete relative to the warmer Kampi ya Mawe. Lower 100-seed weight was reported at Kabete relative to Kampi ya Mawe possibly due to excessive vegetative growth at Kabete. Cluster analysis delineated the germplasm into four clusters all separated from the adapted medium- and long-duration checks. Although overall two distinct diversity groups were observed separating the short, medium-maturing types from the tall late- and very late-maturing types, the separation was relatively marginal suggesting a closer genetic relation between the Ugandan pigeonpea germplasm. Relatively low diversity in qualitative traits was observed in the accessions. The predominance of accessions with pubescent pods, a trait associated with resistance to pod damaging insects may provide an opportunity to identify materials for insect pest resistance for use in breeding.
Identification of Acetobacter strains isolated in Thailand based on the phenotypic, chemotaxonomic, and molecular characterizations

The restriction analysis of 16S-23S rRNA gene internal transcribed spacer regions (ITS) using TaqI, AluI, HpaII, and AvaII revealed that forty-seven bacterial isolates found in fruits and flowers collected in Thailand belong to the genus Acetobacter. They were identified as follows: Group 1 containing 11 isolates was identified as A. pasteurianus, Group 2 containing nine isolates was identified as A. orientalis, Group 3 containing eight isolates was identified as A. lovaniensis, Group 4 including eight isolates was identified as A. indonesiensis, Group 5 containing three isolates was identified as A. tropicalis, Group 6 containing five isolates was identified as A. ghanensis, and Group 7 containing four isolates was identified as A. orleanensis. The differentiation of Acetobacter species by the 16S-23S rRNA gene ITS restriction analysis was discussed. The phenotypic, chemotaxonomic, and molecular characteristics including 16S rRNA gene sequences supported the above-mentioned identification. All Thai isolates were screened for their alcohol dehydrogenase activity and exhibited an activity of 2.05-7.52 units/mg protein at 30 °C. Isolate PHD-23 produced the highest quantity of 1.50% acetic acid (v/v) from 4.0% ethanol (v/v).
Comparison of the ENATE approach and discontinuous Galerkin spectral element method in 1D nonlinear transport equations

In this paper a comparison of the performance of two ways of discretizing the nonlinear convection-diffusion equation in a one-dimensional (1D) domain is performed. The two approaches can be considered within the class of high-order methods. The first one is the discontinuous Galerkin method, which has been profusely used to solve general transport equations, either coupled as the Navier-Stokes equations, or on their own. On the other hand, the ENATE procedure (Enhanced Numerical Approximation of a Transport Equation), uses the exact solution to obtain an exact algebraic equation with integral coefficients that link nodal values with a three-point stencil. This paper is the first of thorough assessments of ENATE by comparing it with well-established high-order methods. Several test cases of the steady Burgers' equation with and without source have been chosen for comparison.
Influence of tactical factors on ERP projects success

This study focuses on tactical factors, namely, Enterprise-wide Communication, User Training and Education, and ERP Vendor Support. The study was conducted using a survey questionnaire. The questionnaires were distributed to ERP users in Iranian organizations. A total of 384 responses were collected and analyzed. A significant relationship was found between enterprise-wide communication, user training and education, and ERP vendor support with ERP implementation success. The outcomes of this study are useful to ERP vendors and consultants to prepare some strategies to overcome the misfit between their ERP products and ERP adopting organizations in developing countries. Moreover, ERP adopting organizations and managers could gain an understanding of the complexities inherent in ERP installations to avoid barriers and increase the likelihood of achieving desired results.
A Generation Method of Automation Test Cases Based on Android

Aiming at the problems that complex testing process, incomplete testing and poor reusability of test cases for Android automated testing methods, we propose a generation method of automation test cases based on control traversal under the guidance of standard path. The method firstly records a test script as a standard path by the tester, then automatically acquires the control in the interface and generates the control relationship graph. Finally, the test case generation method based on the depth-first search was used to traverse the control relationship graph to generate test cases. The test case was used to test the Android mobile App. The results show that the test case generated by this method improves the test coverage and script reusability, simplifies the test operation and proves the feasibility of the method.

Band gaps and quasiparticle energy calculations on ZnO, ZnS, and ZnSe in the zinc-blende structure by the GW approximation

We have calculated the quasiparticle band gaps of ZnO, ZnS, and ZnSe in zinc-blende structure within the GW approximation using a full random-phase approximation dielectric matrix. The linear muffin-tin orbital basis was used for this calculation and the 3d orbitals of the Zn atom were treated as valence band in every case. The calculated band gaps are 3.59, 3.97, and 3.10 eV for ZnO, ZnS, and ZnSe, respectively. The gaps of ZnS and ZnSe are in good agreement with the experimental values and so is the gap of ZnO if we compare it with the experimental optical gap of wurtzite ZnO. @S0163-1829~99! 01139-X#
Formulation development of in-situ nasal drug delivery system of poorly water soluble drug (Indomethacin) using mixed solvency concept and their evaluation

The present study was aimed to develop a mucoadhesive in situ nasal gel containing indomethacin with enhanced drug loading and transnasal permeation properties, which were achieved by improving drug solubility using the concept of mixed solvency. Poloxamer 407 was used as thermosensitive polymer and carbopol 934P as mucoadhesive polymer. Initially solubility of indomethacin was enhanced in aqueous solution by using various solubilizers like sodium benzoate (SB), niacinamide (NM), sodium citrate (SC), urea (UR), propylene glycol (PG) etc, individually and as a combination of three and four solvents, respectively. Maximum solubility of indomethacin was achieved in 30% w/v mixed solvent system containing Sodium benzoate (12% w/w) + Niacinamide (12% w/w) + Sodium citrate (3% w/w) + Propylene Glycol (3% w/w), enhancing solubility of indomethacin by 176.26 times as compared to its solubility in water. In situ gel was prepared by cold technique. Evaluation of the prepared gel was carried out, including properties like phase transition temperature, viscosity, in vitro drug release, drug content, transnasal permeation and stability studies. In vitro drug release studies of aqueous solution of mixed blend were performed and permeability coefficient was found to be 5.2×10 -02 cm/hr and
Occupancy Estimation in Smart Buildings Using Iot-Based Techniques

Nowadays, the research and innovation of smart buildings has been gaining increasingly attentions in building construction and management society. Among a variety of emerging technologies, demand driven HVAC (i.e., heating, ventilation and air conditioning) operation is promising to significantly reduce the building operation cost, and ultimately to achieve sustainable smart buildings. The “Internet of Things (IoT)” is about physical items talking each other, machine to machine communications and person to computer communications will extended to “things”. The Key technologies that drive future IoT related to Smart sensor technologies including Nanotechnology, WSN and Miniaturization . The integrated network architecture and the interconnecting mechanisms for reliable measurements of parameters by smart sensors and transmission of data via internet. In most cases these building HVAC systems run on fixed schedules and do not employ any fine grained control based on detailed occupancy information. In this paper we present the design and implementation of a presence sensor platform that can be used for accurate occupancy detection at the level of individual homes. Our presence sensor is low-cost, wireless, and incrementally deployable within existing buildings. The goal of this analysis is to help designers to select the most relevant parameters to control the energy consumption of buildings according to their context, selecting them as input data of the management system. Following this approach, we select a reference smart buildings with different contexts, and where our automation platform for energy monitoring is deployed.
Optimal Matched Filter in the Low-number Count Poisson Noise Regime and Implications for X-Ray Source Detection

Detection of templates (e.g., sources) embedded in low-number count Poisson noise is a common problem in astrophysics. Examples include source detection in X-ray images, γ-rays, UV, neutrinos, and search for clusters of galaxies and stellar streams. However, the solutions in the X-ray-related literature are sub-optimal in some cases by considerable factors. Using the lemma of Neyman–Pearson, we derive the optimal statistics for template detection in the presence of Poisson noise. We demonstrate that, for known template shape (e.g., point sources), this method provides higher completeness, for a fixed false-alarm probability value, compared with filtering the image with the point-spread function (PSF). In turn, we find that filtering by the PSF is better than filtering the image using the Mexican-hat wavelet (used by wavdetect). For some background levels, our method improves the sensitivity of source detection by more than a factor of two over the popular Mexican-hat wavelet filtering. This filtering technique can also be used for fast PSF photometry and flare detection; it is efficient and straightforward to implement. We provide an implementation in MATLAB. The development of a complete code that works on real data, including the complexities of background subtraction and PSF variations, is deferred for future publication.
Strongly Anisotropic Band Dispersion of an Image State Located above Metallic Nanowires

› 1d image state band and found it to be unconventional because it falls below the freeelectron parabola perpendicular to the In atom rows. The most straightforward explanation for this isthat the electrons feel the surface corrugation potential produced by the rows of In atoms. We wereable to infer the form of the potential from our measurements. [S0031-9007(99)08625-1]
What explains in ation in high income countries ? Evidence from panel data

Models of monetary policy incorporating imperfectly competitive labour markets predict that ination increases with the gap between actual real wages and their competitive levels. We use panel data to test for a link between ination and the labour market characteristics that inuence wage gaps. We also test for e¤ects from central bank independence, trade openness and income per capita. Trade union membership rates, employment protection and coordination in wage bargaining are signi cant. Central bank independence, trade openness and income per capita do not explain temporal variation in ination directly, but do a¤ect the impact of labour market characteristics on ination.
Sustainable procurement portfolio management: a case study in a mining company

Abstract Sustainable procurement is a solution to integrate environmental and social considerations in all steps of procurement process, in order to reduce impacts on human health, environment, and human rights. Despite the existence of important works in this area, more studies for determining how the principles related to sustainable development can be integrated to procurement strategies are needed. This study presents a case study in a mining company to evaluate the elements that should be considered for the implementation of sustainability concept in the contracting of services through the application of a sustainability portfolio model. Results show that the contracts of the internal movement’s category of the studied company fit as Strategic Commodity, which means that the items in this category have a risk in the strategic supply, because they need investments made by the buyer in the relationship with the supplier.
