Published: February 2020

Clinical Relevance
Mechanical surface roughening of the titanium-abutment base is necessary to increase the pull-off bond strength of the lithium disilicate abutment material. Additional chemical surface treatment may further increase the bond strength, but the effects are product specific.

SUMMARY

Objective:
The titanium-cement interface of a Ti-Base implant crown must be able to resist intraoral pull-off forces. The purpose of this study was to evaluate the effect of mechanical and chemical surface treatments of a titanium-abutment base (Ti-Base, Dentsply/Sirona) on the pull-off bond strength of a lithium disilicate abutment coping.

Methods and Materials:
Ti-Bases were divided into nine groups of 10 copings each that varied in both mechanical surface treatment (none; Al2O3 air abrasion; CoJet silicoating, 3M ESPE) and chemical treatments (none; Monobond Plus, Ivoclar Vivadent; Alloy Primer, Kuraray). Lithium disilicate abutment copings (IPS e.max CAD, Ivoclar Vivadent) were designed and milled. After crystallization, the copings were cemented onto the Ti-Bases with a resin cement (MultiLink Hybrid-Abutment Cement, Ivoclar Vivadent) according to the manufacturer's recommendations. The copings were torqued to a mounted implant, and the access channel was sealed with composite. After 24-hour storage and 2000 thermal-cycles in distilled water, the copings were subjected to a removal force parallel to the long axis of the interface until fracture. Data were analyzed with multiple one-way analyses of variance and Tukey post hoc tests (α=0.05).

Results:
Significant differences were found between groups based on type of surface treatment (p&lt;0.05).

Conclusions:
Chemical surface treatment with Monobond Plus and mechanical surface treatment with CoJet silicoating or Al2O3 air abrasion resulted in the greatest pull-off bond strength. Alloy Primer did not provide a statistically significant increased pull-off bond strength when the surfaces were mechanically treated with Al2O3 air abrasion or CoJet silicoating. The lack of any mechanical surface treatment resulted in the lowest pull-off bond strength regardless of the type of chemical surface treatment.
Kanariefågeln som tystnade. Finlands gestalt shift om kinesiska investeringar
Authors: Mattlin Mikael 
Published: February 2020

Av historiska, ekonomiska och säkerhetspolitiska orsaker är Finland ett ”minst sannolikt fall” (least likely case) vad gäller oro över kinesiska investeringar. Finland har inom EU haft det högsta relativa handelsberoendet av Kina. Sedan år 2016 är Finland även ett av de EU-länder som fått mest investeringar från Kina absolut sett. Finland, som inte är NATO-medlem, har oproblematiska relationer till Kina och en öppen ekonomi, som ännu för några år sedan välkomnade kinesiska investeringar. Landet har också en ovanligt lång obruten tradition av inhemsk lagstiftning om utländska investeringar som sedan 1992 kan betecknas som liberal. Under de senaste två åren har det emellertid bland policyeliten och i den allmänna diskussionen skett en drastisk förändring i synen på kinesiska investeringar som närmast kan betecknas som en gestalt shift. En påföljd av detta är att behovet av en bättre helhetsbild om kinesiska investeringar har identifierats. Informationsutbyte och koordinering mellan olika myndigheter har förbättrats på många sätt. Samtidigt har man även fördjupat nordiskt myndighetssamarbete och informationsutbyte om relevant lagstiftning och praxis inom området. Även om samarbete kring utländska investeringar inte ingick i Stoltenberg-rekommendationerna år 2009, så kan man se det som ett naturligt led i intensifierat nordiskt säkerhetssamarbete.
Abstract in English:The Canary That Fell Silent. Finland’s Gestalt Shift on Chinese InvestmentsFor a mixture of historical, economic and security policy reasons Finland can be regarded as a least likely case with regard to apprehensiveness over Chinese investments. Within the EU, Finland has had the highest relative trade dependence on China. Since 2016, Finland is also one of the EU member states that have attracted the most Chinese investment in absolute terms. Finland, which is not a NATO member, has unproblematic relations with China and an open economy that up until a few years ago welcomed Chinese investments. The country also has an unusually long unbroken tradition of domestic legislation regarding foreign investments, which since 1992 can be characterised as liberal. However, during the last two years, there has been a drastic change in views on Chinese investments, both among the policy elite and in the public debate. This change can be regarded as a veritable gestalt shift. As a corollary, a need for a better overview of Chinese investments has been identified. Information exchange and coordination between various governmental departments has been improved in several ways. Simultaneously, cooperation and information exchange between relevant Nordic authorities regarding relevant legislation and praxis has also deepened. Although the 2009 Stoltenberg recommendations did not encompass cooperation on foreign investments, this can be seen as a natural leg in intensified Nordic security cooperation.

Abstract
This paper presents the perceptions of social science students about the use of official statistical data, in the context of active learning of Statistics, and other topics related to Applied Statistics. In order to make these courses more attractive, and to challenge and stimulate statistical education, our students work on projects in which they use official statistical data to explore practical, real-life issues. Their attitudes and perceptions regarding official statistical data sources are very important, both for acquisition of statistical analysis skills, essential for their future professional life, and for improvement of the official data sources. Therefore, we conducted a custom-made survey among students from Romanian higher education institutions (HEIs) and gathered a database with 334 responses, which allowed us to identify the main characteristics, problems and solutions concerning the use of statistical official data sources by university students.

Abstract

Background
The aim of the study was to evaluate the inter- and intrareader variability of the safety margin assessment after microwave ablation of liver tumors using post-procedure computed tomography (CT) images as well as to determine the sensitivity and specificity of identification remnant tumor tissue.

Patients and methods
A retrospective analysis of 58 patients who underwent microwave ablation (MWA) of primary or secondary liver malignancies (46 hepatocellular carcinoma, 9 metastases of a colorectal cancer and 3 metastases of pancreatic cancer) between September 2017 and June 2019 was conducted. Three readers estimated the minimal safety margin in millimeters using side-by-side comparison of the 1-day pre-ablation CT and 1-day post-ablation CT and judged whether ablation was complete or incomplete. One reader estimated the safety margin again after 6 weeks. Magnetic resonance imaging (MRI) after 6 weeks was the gold standard.

Results
The intraclass correlation coefficient (ICC) for estimation of the minimal safety margin of all three readers was 0.357 (95%-confidence interval 0.194–0.522). The ICC for repeated assessment (reader 1) was 0.774 (95%-confidence interval 0.645–0.860). Sensitivity and specificity of the detection of complete tumor ablation, defined as no remnant tumor tissue in 6 weeks follow-up MRI, were 93%/82%/82% and 33%/17%/83%, respectively.

Conclusions
In clinical practice, the safety margin after liver tumor ablation is often assessed using side-by-side comparison of CT images. In the study, we were able to show, that this technique has a poor reliability (ICC 0.357). From our point of view, this proves the necessity of new technical procedures for the assessment of the safety distance.

Arhopalus syriacus es una especie exótica presente en los pinares de Argentina que ataca especies de Pinus. El objetivo de este trabajo fue determinar el tiempo de desarrollo y la supervivencia de A. syriacus a 25 °C usando dieta artificial. Tiempos, tasas de desarrollo, pesos, medidas de cápsulas cefálicas y largo de las larvas fueron observados en condiciones de laboratorio; mientras que la proporción de sexos, emergencia y reproducción de los adultos se registraron utilizando trozas de pinos. Las larvas puparon después de 6, 7, 8 y 9 estadios. El ancho de las cápsulas cefálicas y el largo de las larvas disminuyeron a partir del cuarto y sexto estadio, respectivamente. Las pupas hembra fueron más grandes y pesadas. La supervivencia fue menor en los primeros dos estadios y llegó al 100% en larvas maduras y pupas. Las máximas abundancias de adultos que emergieron de las trozas de pino ocurrieron en los meses de noviembre y diciembre. Los machos adultos vivieron 9,27 ± 0,84 días y fueron más livianos que las hembras, que vivieron 9,12 ± 1,61 días. El número de larvas por hembra fue 80,65 ± 10,62. El ciclo de vida total de A. syriacus duró 298,86 ± 13,66 días.
