SUMMARY

Objective:
To analyze the shrinkage stress, bonding interaction, and failure modes between different low-viscosity bulk fill resin composites and conventional resin composites produced by the same manufacturer or a high-viscosity bulk fill resin composite used to restore the occlusal layer in posterior teeth.

Methods & Materials:
Three low-viscosity bulk fill resin composites were associated with the conventional resin composites made by the same manufacturers or with a high-viscosity bulk fill resin composite, resulting in six groups (n=10). The bonding interaction between resin composites was tested by assessing the microshear bond strength (μSBS). The samples were thermocycled and were tested with 1-mm/min crosshead speed, and the failure mode was evaluated. The post-gel shrinkage (Shr) of all the resin composites was measured using a strain gauge (n=10). The modulus of elasticity (E) and the hardness (KHN) were measured using the Knoop hardness test. Two-dimensional finite element models were created for analyzing the stress caused by shrinkage and contact loading. The μSBS, Shr, E, and KHN data were analyzed using the Student t-test and one-way analysis of variance. The failure mode data were subjected to chi-square analysis (α=0.05). The stress distribution was analyzed qualitatively.

Results:
No significant difference was verified for μSBS between low-viscosity bulk fill resin composites and conventional or high-viscosity bulk fill composites in terms of restoring the occlusal layer (p=0.349). Cohesive failure of the low-viscosity bulk fill resin composites was the most frequent failure mode. The Shr, E, and KHN varied between low-viscosity and high-viscosity resin composites. The use of high-viscosity bulk fill resin composites on the occlusal layer reduced the stress at the enamel interface on the occlusal surface.

Conclusions:
The use of high-viscosity bulk fill resin composites as an occlusal layer for low-viscosity bulk fill resin composites to restore the posterior teeth can be a viable alternative, as it shows a similar bonding interaction to conventional resin composites as well as lower shrinkage stress at the enamel margin.

Multi-Criteria Analysis for Selecting Solid Waste Management Concept Case Study: Rural Areas in Sentani Lake Region, Jayapura
Authors: Alfons Alfred Benjamin , Padmi Tri 
Published: January 2019

Aim: This study aims to identify, develop, and determine the most suitable concept of solid waste management to be applied in Ifale Village, Yobeh Village, Putali Village, Atamali Village, and Asei Besar Village. Until now, the application of solid waste management system in Jayapura is still far from what people expected since it has been unable to serve the communities who live in rural areas on the islands around Sentani Lake. As a result, 12,554.38 liters/day of solid waste generated by the community in these regions is left untreated. Methodology and Results: The study is using the Analytic Hierarchy Process (AHP) method. The AHP calculations show that the idea of handling solid waste in an integrated treatment facility—following the initial sorting on the household scale—has the highest priority weight (2.05) compared to the other alternatives. Hence, it has been chosen as the best solid waste management concept that can be applied to the study sites. Based on the results as well, the main criteria to be considered include the environmental aspects, social aspects, and technical aspects with each weighing value of 0.534, 0.186, and 0.147, respectively. Conclution, significans and impact study: The sub-criteria with the highest priorities to be considered in making the decision are the soil pollution (due to produced leachate), air pollution (potentially in the form of stench and gas emissions), the transmission of disease vectors, public participation, and the operational convenience.

Introduction

Aedes albopictus (Skuse) is an important vector of arboviral diseases, including dengue, chikungunya and Zika virus disease. Monitoring insecticide resistance and mechanisms by which the mosquito develops resistance is crucial to minimise disease transmission.

Aim
To determine insecticide resistance status and mechanisms in Ae. albopictus from different geographical regions.

Methods
We sampled 33 populations of Ae. albopictus from Asia, Europe and South America, and tested these for susceptibility to permethrin, a pyrethroid insecticide. In resistant populations, the target site for pyrethroids, a voltage-sensitive sodium channel (Vssc) was genotyped. Three resistant sub-strains, each harbouring a resistance allele homozygously, were established and susceptibilities to three different pyrethroids (with and without a cytochrome P450 inhibitor) were assayed.

Results
Most populations of Ae. albopictus tested were highly susceptible to permethrin but a few from Italy and Vietnam (4/33), exhibited high-level resistance. Genotyping studies detected a knockdown resistance (kdr) allele V1016G in Vssc for the first time in Ae. albopictus. Two previously reported kdr alleles, F1534C and F1534S, were also detected. The bioassays indicated that the strain homozygous for the V1016G allele showed much greater levels of pyrethroid resistance than other strains harbouring F1534C or F1534S.

Conclusion
The V1016G allele was detected in both Asian and Italian Ae. albopictus populations, thus a spread of this allele beyond Italy in Europe cannot be ruled out. This study emphasises the necessity to frequently and regularly monitor the V1016G allele in Ae. albopictus, particularly where this mosquito species is the main vector of arboviruses.
Beta1-paracompactness with respect to an Ideal
Authors: Cahis Abdo Mohammed 
Published: January 2019

The notion of 1-paracompactness in topological spaces is introduced and studied in [1]. In this paper, we introduce and investigate the notion of \beta_1-paracompact spaces with respect to an ideal I which is a generalization of the notion ofÂ \beta_1-paracompact spaces. We study characterizations, subsets and subspaces of 1I-paracompact spaces. Also, we investigate the invariants of \beta_I-paracompact spaces by functions.

The aim of the experiment was to evaluate total bacteria population and the existence of positive and negative gram bacteria of <em>pelletcalf starter</em> which added by lactic acid bacteria from fermented cabbage waste. The materials in this research were corn, rice bran, soybean meal, mineral mix, molasses, fermented cabbage wasted. The research was conducted by Completely Randomized Design with 4 treatments and 5 replications. The treatments were T0 (100% <em>calf starter</em>), T1 (2% of fermented cabbage waste + 100% <em>calf starter</em>), T2 (4% of fermented cabbage waste + 100% <em>calf starter</em>) and T3 (6% of fermented cabbage waste + 100% <em>calf starter</em>). The Variables observed were bacteria population and gram bacteria. Data of bacteria population were evaluated by descriptive analysis, while data of gram bacteria existence were statistically analyses by variance analysis, if there were significantly affect continued by Duncan test. The results showed that the highest bacteria population was on the treatment with addition level 2% of fermented cabbage waste and the lowest bacteria population was on addition level 6%. Adding fermented cabbage waste did not significantly effect to the existence of gram bacteria. The average score of gram bacteria existence on added fermented cabbage waste from level 0%, 2%, 4%, and 6% were respectively 1.99; 2.10; 2.29 and 2.29. Positive gram bacteria extended increased with increased fermented cabbage waste. The conclusion was the <em>pellet calf starter</em> which added with lactic acid bacteria produced bacteria and there was positive gram bacteria, and suppress negative bacteria.
