Objectives: White spot lesions after fixed orthodontic treatment will increase bacterial plaque formation due to increased enamel surface roughness. The aim of this study was to analyze the surface roughness of white spot lesions on enamel after a microabrasion technique, a microabrasion technique combined with calcium phosphopeptide-amorphous calcium phosphate (CPP-ACP) application, and a microabrasion technique combined with fluoride application.Methods: Artificially induced white spot lesions on the enamel surfaces of 42 maxillary first premolars were randomly assigned into one of three treatment groups (n=14): (a) A microabrasion technique, (b) a microabrasion technique combined with CPP-ACP application, and (c) a microabrasion technique combined with fluoride application. A Mitutoyo SJ-301 surface roughness tester was used to measure differences in surface roughness before and after treatment, and the after treatment measurements were compared among the three groups.Results: A significant difference in surface roughness was noted for the white spot lesions on enamel before and after treatment in all groups (p<0.05). A significant difference was also found when comparing the after treatment surface roughness in all groups.Conclusion: The combination of the microabrasion technique with CPP-ACP application significantly reduced enamel surface roughness when compared to microabrasion alone or the combination of microabrasion and fluoride application.

Objective: Patients generally experience some level of anxiety during dental treatments. Salivary alpha amylase (SAA) can be used as a biomarker for anxiety. This study aimed to compare SAA levels between children who had never and had undergone tooth extraction procedures with a local anesthetic injection.Methods: Thirty-seven participants aged 6–11 years who were to undergo the extraction of primary teeth at the Dental and Oral Educational Hospital, Faculty of Dentistry Universitas Indonesia, were enrolled. The subjects were divided into two groups: One group consists of 20 children who had never undergone a tooth extraction, and the other group consists of 17 children who had undergone tooth extraction. From all children, one saliva sample was collected using a portable saliva strip 10 min before (t0), shortly after (t1), and 10 min after (t2) local anesthetic injection, and the SAA activity was determined using a portable Nipro Cocoro Meter device. The SAA levels of both groups were analyzed using the Mann-Whitney U test.Results: There were significant differences in SAA levels at t0 (p=0.001), t1 (p=0.018), and t2 (p=0.021) in both groups. Anxiety is a combination of behavioral and physiological reactions. SAA release is regulated by autonomic innervation, and the SAA level increases owing to acute stress.Conclusion: Dentists should note patients’ negative dental experiences to provide more effective and less traumatic treatment.
A temporal profile of pro-abstinence-oriented constructs from the modified theory of planed behavior in a Slovenian clinical sample of treated alcoholics – an 18-year follow-up
Authors: Radovanović Mirjana , Rus-Makovec Maja 
Published: January 2018

Abstract

Introduction
Using the modified Theory of Planned Behaviour (mTPB), different indicators of therapeutic success were studied to understand pro-abstinence behavioural orientation during an 18-year after-care period following a 3-month intensive alcoholism treatment. The indicators were: perceived needs satisfaction (NS), normative differential (ND), perceived alcohol utility (UT), beliefs about treatment programme benefits (BE) and behavioural intentions (BI).

Methods
The sample of 167 patients who consecutively started an intensive alcoholism treatment programme has been followed-up for 18 years, using standardised ailed instruments at the end of the treatment, and in the years 4-5, 9 and 18 of follow-up. The last data collection was completed by 32 subjects in 2010. The analysis followed the standard explore-analyse-explore approach. After the initial descriptive exploration of data, multivariate analysis of variance (MANOVA) in SPSS statistical package was set to explore between-groups and within-groups differences over time.

Results
At the between-group level, BI remained stable at the same level as at the end of the treatment programme, whereas BE and UT robustly changed over time and levelled off after 10 years of follow-up. NS and ND show a trend of pro-abstinent orientation and level off after 10 years of follow-up, although the trend is not significant. The same results were confirmed by the within-subject level.

Conclusions
Studied constructs stabilised after ten years of follow-up, apart from BI. The latter suggests that BI level needed for completion of an intensive treatment programme suffices for the maintenance of abstinence when accompanied by the change in perception of alcohol usefulness.

Abstract

Introduction
The aim of the study was to analyse the deviations of the body posture and to assess the occurrence of spine deformities. Additionally, Body Mass Index in school children was related to the trend in postural deformities for different age groups (5-8 years old, n=112; 9-11 years old, n=205; 12-14 years old, n=212) as part of the project “Spine Lab”, granted from the European Commission IPA founds, investigating the importance of public health issues.

Methods
Body posture was measured using Contemplas 3D software analyser, based on video image trajectory and BIA weight scale (Tanita BC 420). Overall, 17 variables were assessed, and differences were confirmed using MANOVA analysis.

Results
The results showed that there is a significant difference between age groups for the measured variables (F=9.27; p<0.01; η2=0.26), suggesting a moderate difference across the age span.

Conclusion
The study results showed that there is a negative trend of increasing Body Mass Index within the first and youngest age group. The fact is that the trend of increasing deformity of the shoulder belt has been noted, often inclining towards the formation of milder forms of kyphotic posture. Other forms of deformity that are accentuated in the survey results are the negative trend of increasing pelvic rotation and pelvis rotation which inclines towards the formation of lordotic posture for all three age groups.

One way to increase service coverage of telecom operators such as PT. Smartfren is by adding or building new Base Transceiver Stations (BTS). To determine where to place the new BTS, there are several criteria and sub criteria that must be considered. Incorrect choice of criteria and sub criteria or lack of data can cause the new BTS to be built in a less precise location thus the service coverage will not be optimal. Based on that consideration, a decision-making system application to determine BTS location is created using Fuzzy AHP method with VB and MySQL applications. The outcome of this application is a list of area, in several regencies, from the highest to the lowest score of BTS location based on the selected criteria and sub-criteria. It helps the user in knowing the most appropriate location for the placement of PT. Smartfren’s new BTS.

The rising costs for the fossil fuel based energy and concern over the environment have caused a resurgence of interest in anaerobic treatment and subsequent use of the biogas produced during the treatment of organic waste as fuel. Biogas from cattle dung has become a potential renewable energy source for both domestic and commercial usage especially in Lombok. Unfortunetly, due to the presence of carbon dioxide (CO2) and Hydrogen sulphide (H2S) in biogas, it has become extremely difficult to store and transport it effectively and has lower energy density.This paper presents the study in biogas purification by mean of absorbing the CO2 gas using the NaOH solution. In addition, the biogas production process used in 3 (three) kinds of cattle dung from horses dung, cows dung and buffaloes dung by the composition of 1 kg of manure to 1 Liter of water. The results show that generated the largest volume on the composition of C with average volume reached 72.419 liters, then the composition B reached 61.794 liters, and the lowest in the composition of A with an average volume of 51.478 liters. The highest power generated in the treatment composition A with 2.5 N NaOH solution at 108.5 watts and the lowest power generated by the composition of C without treatment of 25.67 Watts.
Prediction and Measurement of Pressure Drop of Water Flowing in a Rectangular Microchannel
Authors: Mirmanto M. 
Published: January 2018

This paper presents experimental results of pressure drop measurement and prediction of water flowing through a copper rectangular microchannel with a hydraulic diameter of 437 µm. The aim of this work is to identify discrepancies between experimental data and macrochannel theory. An inlet temperature of 60oC was kept constant at the channel entrance and the experiments were performed with Reynolds numbers (based on the mean velocity and hydraulic diameter) ranging up to 4500. The results show that the pressure drop prediction agrees with the theory. However, the trend of Poiseuille number with the Reynolds number was not constant for laminar flow. This could be due to the entrance effect. Moreover, the friction factor theory could predict the experimental data for turbulent flow. Thus, in this experiment, the theory for flow in macro passages is still applicable.

ABSTRACTDue to population growth, industry advance and rapid development, fresh and comfortable air may be difficult to get. Conditioning the air to get comfort environment may be a basic demand for people, but the prices of the device and its operation for this purpose are expensive. This research tries to solve this problem but it is just only to know the capability of the heat exchanger to transfer/ absorb heat and is not to cool the room to be below the ambient temperature. The working fluid used was clean water and the heat exchangers employed were parallel and serpentine which were made of copper pipes with a diameter of 1/4 inch and 1/2 inch (for the header). The volumetric flow rates used were 300 ml/minutes, 400 ml/minutes and 500 ml/minutes. While the heat that should be absorbed by the water from the room is 50 W, 100 W and 150 W. The results show that the effect of volumetric flow rate on heat exchanger performance and room temperature is insignificant. From the pressure drop results, the parallel pipe heat exchanger has lower pressure drops while the serpentine has higher pressure drops.

« À fleur de peau » : dans cet article qui s’appuie sur son approche spécifique du corps dans la psychothérapie, Christian Devillers nous propose de « rencontrer la sensibilité infime, intime » pour comprendre ce qu’il nomme la « soif de position » et la façon dont la perception de soi inscrite au niveau corporel est sollicitée chaque fois que notre existence ou la reconnaissance de notre existence est ébranlée. Il décrit comment la sensation d’exister émerge du processus complexe d’interaction dès la période prénatale. Elle n’est pas une construction mentale mais une expérience traversée à partir des organes proprioceptifs et sensoriels. Ses mots gagnent à être écoutés avec tous nos sens. Christian fait des liens entre différentes approches du développement et les concepts d’AT, en particulier le protocole, les positions de vie et les signes de reconnaissance. M.M.
