Motivational Interviewing in Improving Oral Health: A Systematic Review of Randomized Controlled Trials
Authors: Gao Xiaoli , Lo Edward Chin Man , Kot Shirley Ching Ching , Chan Kevin Chi Wai 
Published: June 2013

Background: The control and management of many oral health conditions highly depend on one's daily self‐care practice and compliance to preventive and curative measures. Conventional (health) education (CE), focusing on disseminating information and giving normative advice, is insufficient to achieve sustained behavioral changes. A counseling approach, motivational interviewing (MI), is potentially useful in changing oral health behaviors. This systematic review aims to synthesize the evidence on the effectiveness of MI compared with CE in improving oral health.Methods: Four databases (PubMed MEDLINE, Web of Science, Cochrane Library, and PsycINFO) were searched to identify randomized controlled trials that evaluated the effectiveness of MI compared with CE in changing oral health behaviors and improving oral health of dental patients and the public. The scientific quality of the studies was rated, and their key findings were qualitatively synthesized.Results: The search yielded 221 potentially relevant papers, among which 20 papers (on 16 studies) met the eligibility criteria. The quality of the studies varied from 10 to 18 out of a highest possible score of 21. Concerning periodontal health, superior effect of MI on oral hygiene was found in five trials and was absent in two trials. Two trials targeting smoking cessation in adolescents failed to generate a positive effect. MI outperformed CE in improving at least one outcome in four studies on preventing early childhood caries, one study on adherence to dental appointments, and two studies on abstinence of illicit drugs and alcohol use to prevent the reoccurrence of facial injury.Conclusions: Reviewed randomized controlled trials showed varied success of MI in improving oral health. The potential of MI in dental health care, especially on improving periodontal health, remains controversial. Additional studies with methodologic rigor are needed for a better understanding of the roles of MI in dental practice.

Published: June 2013

Background: The aim of this study is to characterize and evaluate the host response caused by three different models of experimental periodontitis in mice.Methods: C57BL/6 wild‐type female mice were distributed into six experimental groups and sacrificed at 7, 15, and 30 days after the induction of periodontal disease: 1) group C: no treatment control group; 2) group L: periodontal disease induced by ligature; 3) group G‐Pg: oral gavage with Porphyromonas gingivalis (Pg); 4) group G‐PgFn: oral gavage with Fusobacterium nucleatum + Pg; 5) group I‐Pg: heat‐killed Pg injected into the palatal mucosa between the molars; and 6) group I‐V: phosphate‐buffered saline injected into the palatal mucosa. The samples were used to analyze the immune‐inflammatory process in the gingival tissue via descriptive histologic and real‐time polymerase chain reaction analyses. The alveolar bone loss was evaluated using microcomputed tomography. The data were analyzed using the Kruskal‐Wallis test, followed by a post hoc Dunn test and analysis of variance, followed by a Tukey test using a 5% significance level.Results: Only the ligature model displayed significant alveolar bone loss in the initial period (7 days), which was maintained with time. The group injected with heat‐killed Pg displayed significant alveolar bone loss starting from day 15, which continued to progress with time (P <0.05). A significant increase (P <0.05) in the gene expression of proinflammatory cytokines (interleukin‐6 and ‐1β) and proteins involved in osteoclastogenesis (receptor activator of nuclear factor‐κB ligand and osteoprotegerin) was observed in the ligature group on day 7.Conclusion: The ligature and injection of heat‐killed Pg models were the most representative of periodontal disease in humans, whereas the oral gavage models were not effective at inducing the disease under the experimental conditions.

Published: June 2013

Background: There are scarce data on the impact of the periodontal condition in the control of biomarkers in patients with cardiovascular disease (CVD). The aim of this study is to assess whether periodontal inflammation and tissue breakdown are associated with C‐reactive protein (CRP) and lipids in patients with stable heart disease.Methods: This cross‐sectional study included 93 patients with stable coronary artery disease (57 males; mean age: 63.5 ± 9.8 years) who were in outpatient care for at least 6 months. After applying a structured questionnaire, periodontal examinations were performed by two calibrated periodontists in six sites per tooth at all teeth. Blood samples were collected from patients on the day of periodontal examination to determine levels of CRP, lipids, and glycated hemoglobin. Multiple linear regression models were fitted to evaluate the association among different periodontal and blood parameters controlling for sex, body mass index, glycated hemoglobin, use of oral hypoglycemic drugs, and smoking.Results: Overall, the sample presented high levels of periodontal inflammation and tissue breakdown. Unadjusted mean concentrations of triglycerides (TGs), very‐low‐density lipoprotein cholesterol, and glucose were significantly higher in individuals with severe periodontitis. When multiple linear regression models were applied, number of teeth with clinical attachment loss ≥6 mm and presence of severe periodontitis were significantly associated with higher CRP concentrations. Bleeding on probing was significantly associated with TGs, total cholesterol, and non‐high‐density lipoprotein cholesterol.Conclusion: In this sample of patients with stable CVD, current periodontal inflammation and tissue breakdown are associated with cardiovascular inflammatory markers, such as CRP and lipid profile.
Increasing CO2-Storage Efficiency Through a CO2/Brine-Displacement Approach
Authors: Akinnikawe Oyewande , Chaudhary Anish , Vasquez Oscar , Enih Chijioke , Ehlig-Economides Christine A. 
Published: June 2013

SummaryPrevious studies have shown that bulk carbon dioxide (CO2) injection in deep saline aquifers supplies insufficient aquifer storage efficiency and causes excessive risk because of aquifer pressurization. To avoid pressurization, we propose to produce the same volume of brine as is injected as CO2 in a CO2/brine displacement. Two approaches to CO2/brine displacement are considered—an external brine-disposal strategy in which brine is disposed of into another formation such as oilfield brine and an internal saturated brine-injection strategy with which the produced brine is desalinated and reinjected into the same formation. The displacement strategies increase the storage efficiency from 0.48% for the bulk-injection case to more than 7%. A conceptual case study with documented aquifer properties of the Woodbine aquifer in Texas indicates that the available volume is sufficient to store all the CO2 being generated by power plants in the vicinity for approximately 20 years only. However, the CO2/brine displacement increases storage efficiency enough to store the CO2 produced for at least 240 years at the current rate of coal-fired electric-power generation. Sensitivity analyses on relative permeability, permeability, and temperature were conducted to see the effects of these reservoir parameters on storage efficiency.For bulk injection, increased permeability resulted in increased storage efficiency, but for the CO2/brine-displacement strategies, decreased permeability increased storage efficiency because this resulted in higher average pressure that increased CO2 storage per unit of pore volume (PV) and increased CO2 viscosity. Also, storage efficiencies for the displacement strategies were highly sensitive to relative permeability. There is an optimal CO2-injection temperature below which the formation-fracturing pressure is lowered and above which CO2 breakthrough occurs for a smaller injection mass. The CO2/brine-displacement approach increased capital expenditures for additional wells and an operating expense for produced-brine disposal, but these additional costs are offset by increased CO2-storage efficiency at least 12 times that achieved by the bulk-injection strategy.

Authors: Wang S.. , Zhang H.-Q.. -Q. , Sarica C.. , Pereyra E.. 
Published: June 2013

Summary
In this experimental study, measurements and observations have been carried out for high-viscosity oil/water/gas three-phase flows in horizontal and upward vertical pipes. Oil with viscosities between 0.15 and 0.57 Pa·s corresponding to temperatures from 37.8 to 15.6°C, filtered tap water, and natural gas at 2.59 MPa pressure are used as the three phases. Superficial oil and water velocities range from 0.1 to 1.0 m/s, and superficial gas velocity varies from 1.0 to 5.0 m/s. The internal diameter of the pipe is 5.25 cm. The experimental measurements include pressure gradient and liquid holdup. The flow-pattern and slug characteristics are observed and the images are recorded with a high-speed video camera system through a high-pressure sapphire window. The experimental results are compared with the predictions of the Zhang and Sarica (2006) unified model (UM), and the discrepancies are identified.
Improved Heinz inequalities via the Jensen functional

Published: June 2013

Abstract
By virtue of convexity of Heinz means, in this paper we derive several refinements of Heinz norm inequalities with the help of the Jensen functional and its properties. In addition, we discuss another approach to Heinz operator means which is more convenient for obtaining the corresponding operator inequalities for positive invertible operators.
Spatio-temporal patterns along a primary succession on alluvial sediments
Authors: Ignjatović Maša , Kaligarič Mitja , Škornik Sonja , Ivajnšič Danijel 
Published: June 2013

Abstract
Dynamic alluvial landscapes offer many possibilities to study primary succession processes on newly developed habitats. However, within the Central European environmental conditions, where watercourses and their riparian spaces are under severe anthropogenic pressures — water regulation, deforestation, lowering of groundwater — natural processes are limited. We studied primary succession on alluvial stream deposits in an artificial lake, where we aimed to follow the terrestrialisation rate and habitat turnover, along with plant species richness and composition across successional stages. In 30 years, a pristine white-willow riparian forest developed. One half of the initially aquatic habitat became terrestrial. The frequency of change, studied on 11250 quadrats 10×10 m each (on a scale from “no change” to 8 changes) and the mean of change per habitat type (most of the habitats changed 2 to 3 times) revealed only one successional trajectory. The percentage flow chart showed a deterministic pathway of succession. The “time since formation” of a terrestrial habitat shows that more than 20% of the lake was terrestrialised within in the first ten years. We studied species richness and composition along three composed transects, following successional stages. We found that the newly assembled riparian white willow woodland has a surprisingly low colonisation rate of plant species.
Number of ghost crab burrows does not correspond to population size
Authors: Silva Willian , Calado Tereza 
Published: June 2013

Abstract
Ghost crabs are distributed worldwide on sandy beaches, and several studies have associated the number of ghost crab burrows with the levels of anthropogenic impacts on the beaches under study. However, our results show that the use of ghost crab Ocypode quadrata burrows to assess levels of anthropogenic impacts on sand beaches may not be accurate, as previously thought, because the number of burrows does not represent an estimate of the population size. In addition, we propose three hypotheses to explain the extremely low number of individuals/number of burrows ratio: the “secret chamber”, the “multiple openings”, and the “one crab, several burrows” hypotheses. We also observed an unusual sex ratio.
Cladonia lichens as the most effective and essential pioneers in strongly contaminated slag dumps
Authors: Osyczka Piotr , Rola Kaja 
Published: June 2013

Abstract
The epigeic lichen biota of ten post-smelting slag dumps were studied to identify the ecological importance of Cladonia species in spontaneous succession within artificial areas. Species diversity, abundance, constancy and cover indices were determined at the initial stages of vegetation establishment. Substrates under lichen vegetation were characterised in terms of the pH, organic C and total N content, C/N ratio and Zn, Pb, Cd and As concentration. Species occurrence and abundance indices were related to habitat type, enabling the ability to identify species-specific responses to environmental factors. Despite the unfavourable and artificial habitat conditions at dump sites, some Cladonia appear abundant and form swards, with Cladonia rei as a dominant species. They appear to be well-adapted for slag substrate and their special arrangement illustrative of site contamination. Certain sward-forming Cladonia lichens play a fundamental role as effective pioneers in the initial stage of succession and provide stable plant cover development.
Existence of derivations on near-rings
Authors: Kamal Ahmed , Al-Shaalan Khalid 
Published: June 2013

Abstract
We obtain conditions on (R,+) which force that the zero map is the only derivation on a zero-symmetric near-ring R. Throughout the paper we construct several new examples of near-rings which are not rings admitting non-zero derivations, non-zero (σ, σ)-derivations and non-zero (1, σ)-derivations.

Strongly nonatomic densities defined by certain matrices
Authors: Boos Johann , Leiger Toivo 
Published: June 2013

Abstract
Drewnowski and Paúl proved about ten years ago that for any strongly nonatomic submeasure η on the power set P(ℕ) of the set ℕ of all natural numbers the ideal of all null sets of η has the Nikodym property (NP). They stated the problem whether the converse is true in general. By presenting an example, Alon, Drewnowski and Łuczak proved recently that the answer is negative. Nevertheless, it is of mathematical interest to identify classes of submeasures η such that η is strongly nonatomic if and only if the set of all null sets of η has the Nikodym property. In this context, the authors proved some years ago that this equivalence holds, for instance, if one restricts the attention to the case of densities defined by regular Riesz matrices or by nonnegative regular Hausdorff methods. Also sufficient and necessary conditions in terms of the matrix coefficients are given, that the defined density is strongly nonatomic. In this paper we extend these investigations to the class of generalized Riesz matrices, introduced by Drewnowski, Florencio and Paúl in 1994.
CD-ROM encyclopedias: Extending the Gutenberg galaxy to include computer multimedia technologies
Authors: Wasiak Patryk 
Published: June 2013

Abstract
The aim of this article is to discuss the “multimedia encyclopedia” genre launched in the 1980s, the era of “the multimedia revolution.” Encyclopedias of this kind were released on CD-ROM by several well-respected encyclopedia publishers and were widely discussed as an innovation which would lead to information and communication technologies extending rather than replacing the Gutenberg Galaxy. While discussing the launch of multimedia encyclopedias I aim to show how the culture of the printed word was perceived in “the information revolution” discourse of the time by relevant cultural intermediaries.
Combining SPOT 5 imagery with plotwise and standwise forest data to estimate volume and biomass in mountainous coniferous site
Authors: Dimitrov Petar , Roumenina Eugenia 
Published: June 2013

AbstractIn this study, regression-based prediction of volume and aboveground biomass (AGB) of coniferous forests in a mountain test site was conducted. Two datasets — one with applied topographic correction and one without applied topographic correction — consisting of four spectral bands and six vegetation indices were generated from SPOT 5 multispectral image. The relationships between these data and ground data from field plots and national forest inventory polygons were examined. Strongest correlations of volume and AGB were observed with the near infrared band, regardless of the topographic correction. The maximal correlation coefficients when using plotwise data were −0.83 and −0.84 for the volume and AGB, respectively. The maximal correlation with standwise data was −0.63 for both parameters. The SCS+C topographic correction did not significantly affect the correlations between spectral data and forest parameters, but visually removed much of the topographically induced shading. Simple linear regression models resulted in relative RMSE of 32–33% using the plotwise data, and 43–45% using the standwise data. The importance of the source and the methodology used to obtain ground data for the successful modelling was pointed out.
Air recirculation and ventilation in the coastal regions of the Black Sea
Authors: Surkova Galina 
Published: June 2013

AbstractAn initial investigation of recirculation is carried out for the coast of the Black Sea. The local mesoscale circulations (land-sea breezes, mountain and valley winds) in coastal areas are shown to be an additional risk factor in creating favorable conditions for air stagnation and accumulation of air pollutants in the surface atmosphere layer. Two types of annual recirculation patterns are revealed for northern and north-eastern coast of the Black Sea. Long-term changes in recirculation are investigated. It is shown that the recirculation parameter values remained quasistable until the mid-1970s. Since 1976–1977, steady intensification of recirculation in both winter and summer is identified.

Authors: Trinh Phan , Vinh Hoang , Huong Nguyen , Liem Ngo 
Published: June 2013

AbstractBased on remote sensing, geological data, geomorphologic analysis, and field observations, we determine the fault system which is a potential source of earthquakes in Hoa-Binh reservoir. It is the sub-meridian fault system composed of fault segments located in the central part of the eastern and western flanks of the Quaternary Hoa-Binh Graben: the Hoa-Binh 1 fault is east-dipping (75–80°), N-S trending, 4 km long, situated in the west of the Hoa-Binh Graben, and the Hoa-Binh 2 is a west-dipping (75–80°), N-S trending; 8.4 km long fault, situated in the east of the Hoa-Binh Graben. The slip rate of normal fault in Hoa-Binh hydropower dam was estimated at 0.3–1.1 mm/yr. The Maximum Credible Earthquake (MCE) and Peak Ground Acceleration (PGA) in the Hoa-Binh hydropower dam have been assessed. The estimated MCE of HB.1 and HB.2 is 5.6 and 6.1 respectively, and the maximum PGA at Hoa-Binh dam is 0.30 g and 0.40 g, respectively. The assessment of seismic hazard in Hoa-Binh reservoir is a typical example of seismic hazards of a large dam constructed in an area of low seismicity and lack of law of seismic attenuation.
Neuro-fuzzy reaping of shear wave velocity correlations derived by hybrid genetic algorithm-pattern search technique
Authors: Asoodeh Mojtaba , Bagheripour Parisa 
Published: June 2013

AbstractShear wave velocity is a critical physical property of rock, which provides significant data for geomechanical and geophysical studies. This study proposes a multi-step strategy to construct a model estimating shear wave velocity from conventional well log data. During the first stage, three correlation structures, including power law, exponential, and trigonometric were designed to formulate conventional well log data into shear wave velocity. Then, a Genetic Algorithm-Pattern Search tool was used to find the optimal coefficients of these correlations. Due to the different natures of these correlations, they might overestimate/underestimate in some regions relative to each other. Therefore, a neuro-fuzzy algorithm is employed to combine results of intelligently derived formulas. Neuro-fuzzy technique can compensate the effect of overestimation/underestimation to some extent, through the use of fuzzy rules. One set of data points was used for constructing the model and another set of unseen data points was employed to assess the reliability of the propounded model. Results have shown that the hybrid genetic algorithm-pattern search technique is a robust tool for finding the most appropriate form of correlations, which are meant to estimate shear wave velocity. Furthermore, neuro-fuzzy combination of derived correlations was capable of improving the accuracy of the final prediction significantly.
Map presentation of changes in Europe’s artificial surfaces for the periods 1990–2000 and 2000–2006
Authors: Feranec Jan , Soukup Tomas 
Published: June 2013

AbstractThe landscapes of the world are constantly changing under the influence of human activities leading to the growth of artificial surfaces. The covering of soil by artificial surfaces is referred to as soil sealing. Aerial and satellite images or data derived from them (for instance CORINE land cover — CLC data used here) provide important information that makes it possible to assess the occurrence, area and rate of soil sealing. As the term sealed soil cannot be wholly identified with the content of the appropriate CLC classes, the term land cover flow urbanization (LCFU) will be used here. The essence of this study is the demonstration and documentation of the trends of the LCFU in Europe for the periods 1990–2000 and 2000–2006 on a single map. This may contribute to a better spatial awareness of the ongoing transformation of landscape under the effects of human activities in an pan-European context. Changes in the LCFU can be seen on a map, compiled from 3 × 3 km squares at an all-European scale, using colours and their hues, to fulfil the role both of identification and classification. The colour method employed makes it possible to perceive three groups of LCFU changes on two time horizons, that is, whether the rate of LCFU in 2000–2006 increased or remained the same (hues of red); or dropped compared to the 1990–2000 period (hues of light to dark blue). The third group represents the LCFU with rates higher or lower than the average (countries with changes recorded in only one time horizon are presented in dark and light magenta colours).
