Objectives: Implant-supported restorations are generally used for the replacement of the lost teeth. Stability against masticatory forces and proper retention are critical for optimal durability of restorations. The aim of this experimental study was to compare the retention of cobalt-chromium (Co-Cr) copings made by different techniques. Materials and Methods: Twenty-four solid abutment analogs were mounted and scanned with a desktop scanner. They were divided into two groups (n=12) and received metal copings fabricated by either soft or hard Co-Cr alloy. Soft Cera­mill Sintron Co-Cr patterns were milled and sintered. Hard Co-Cr blocks were milled in a milling machine. The copings were sandblasted, polished, adjusted, and placed on the respective abutments. The frequency of adjustments was recorded for each abutment. The copings were cemented with zinc phosphate cement and underwent tensile test by a universal testing machine. The Mann-Whitney test and t-test were used to compare the two groups (α=0.05). Results: There was no significant difference in retention of copings between the experimental groups. The mean retentive force was 559.58±115.66 N and 557.13 ±130.48 N for the soft and hard metal groups, respectively (P=0.96). Considering the non-normal distribution of adjustment frequency data, the Mann-Whitney test showed that the frequency of adjustments was significantly higher in the hard metal group than the soft metal group (9.5 versus 0.1667; P<0.001). Conclusion: Although hard metal copings required more adjustments, retention of soft and hard Co-Cr copings was not significantly different.

In order to increase the income of tea smallholder and maintain the sustainability of tea, Dewan Teh Indonesia collaborated with Business Watch Indonesia in establishing a local certification scheme that is called as Lestari Tea Certification Program. This certification program has been conducted at some areas since 2011 until 2013 and one of the areas was Campaka sub-district, Cianjur. This research aimed at analysing the sus­tainability impact of the certification program by questionnaire and interview data collection. Analysing sustainability is conducted by using Mann-Whitney test by comparing the per­ception of the tea farmers who participated and those who didn’t participate on the certification program. Independent sample t test is also used to test the differentiation of the mean the income and transportation vehicle and com­munication asset between member of Tea Lestari Certification Program and those who are not. Moreover, logistic regression is used to know which variable more influence the probability for the tea farmers to join the certification program. The output of Mann-Whitney test shows that there is significant difference on the aspect of environment, economy, and social between tea farmers that participated and those who didn’t participate on the certification program. Logistic reg­ression output shows that education level, size of plantation land, and location of village influence the probability of the tea farmers whether to join or not join the Lestari Tea Cerfication Program.

The introduction of new digital technologies represents an important advance to fabricate metal–ceramic restorations. However, few studies have evaluated the influence of these technologies on the fit of the restorations. The aim of this study was to evaluate the effect of different manufacturing techniques and pontic design on the vertical marginal fit of cobalt–-chromium (Co–Cr) posterior fixed partial dentures (FPDs) frameworks. Methods: Eighty stainless-steel dies were prepared to receive 3-unit FPDs frameworks with intermediate pontic (n = 40) and cantilever pontic (n = 40). Within each design, the specimens were randomly divided into four groups (n = 10 each) depending on the manufacturing technique: casting (CM), direct metal laser sintering (LS), soft metal milling (SM), and hard metal milling (HM). The frameworks were luted, and the vertical marginal discrepancy was assessed. Data analysis was made using Kruskal–Wallis and Mann–Whitney U tests (α = 0.05). Results: The vertical marginal discrepancy values of all FPDs were below 50 μm. The HM frameworks obtained the lowest misfit values in both designs. However, no differences were found among intermediate pontic groups or cantilevered groups. Likewise, when differences in a marginal discrepancy between both framework designs were analyzed, no differences were observed. Conclusions: The analyzed digital technologies demonstrated high precision of fit on Co–Cr frameworks and on both pontic designs.

Purpose Building information modeling (BIM) inclusion in education pedagogy is crucial in preparing skilled graduates for employment in the construction industry. Against this backdrop, studies on BIM education abound in architecture, engineering and construction (AEC) programmes in higher education institutions (HEIs). However, there are limited empirical studies on BIM potentials in the quantity surveying (QS) profession in HEIs, particularly in developing countries. The purpose of this study is to identify and assess the BIM drivers and benefits as important to the QS profession using an empirical approach. Design/methodology/approach A comprehensive literature review was conducted to identify the BIM drivers and benefits in relation to the QS profession, which was used to design a questionnaire. To capture a broad perception, a questionnaire survey was carried out which targeted the academia and final year undergraduate students from two selected universities offering QS honour degree programmes in Nigeria. Data collected were analysed using mean score, standard deviation and Mann–Whitney test. Findings The study identified 12 BIM drivers in relation to the QS profession and the analysis of the ranking revealed that almost all the identified BIM drivers are considered by respondents as important. The study further identified 14 BIM benefits and the analysis of the ranking indicated that all the identified BIM benefits are considered as important. The results of the Mann–Whitney test indicated a slight statistically significant difference, particularly in one of the selected universities on the ranking of the BIM drivers and benefits as important to the QS profession. Practical implication The findings of the study provide empirical evidence on the current perceptions of the drivers and benefits of BIM to QS academia and students as they explore the concept for the advancement of QS profession. Originality/value This study would provide practical insights to use BIM for QS practice. Also, this study would contribute to improving the QS graduates and professional quantity surveyors understanding of the BIM knowledge applicable to QS profession.

The aim of this study was to compare, in different periods of time, the compressive and diametral tensile strength of a traditional high viscous glass ionomer cement: Fuji IX (GC Corporation), with two new Brazilian GIC's: Vitro-Molar (DFL) and Bioglass R (Biodinamica), all indicated for the Atraumatic Restorative Treatment (ART) technique. Fifteen disk specimens (6.0mm diameter x 3.0mm height) for the diametral tensile strength (DTS) test and fifteen cylindrical specimens (6.0mm diameter x 12.0mm height) for the compressive strength (CS) test were made of each GIC. Specimens were stored in deionized water at 37º C and 100% of humidity in a stove until testing. Five specimens of each GIC were submitted to CS and DTS test in each period, namely 1 hour, 24 hours and 7 days. The specimens were tested in a testing machine (Emic) at a crosshead speed of 1.0mm/min for CS and 0.5mm/min for the DTS test until failure occurred. The data were submitted to two-way ANOVA and Tukey tests (alpha=0.05). The mean CS values ranged from 42.03 to 155.47MPa and means DTS from 5.54 to 13.72 MPa, with test periods from 1h to 7 days. The CS and DTS tests showed no statistically significant difference between Fuji IX and Vitro Molar, except for CS test at 1-hour period. Bioglass R had lowest mean value for CS of the cements tested. In DTS test Bioglass R presented no statistically significant differences when compared with all others tested GICs at 1-hour period and Bioglass R presented no difference at 24-hour and 7-day periods when compared to Vitro-Molar. Further studies to investigate other physical properties such as fracture toughness and wear resistance, as well as chemical composition and biocompatibility, are now needed to better understand the properties of these new Brazilian GIC's.

This study evaluated the use of hydrogel on the development of Rapanea ferruginea under water restriction through Vibrational Fourier Transform Infrared Spectroscopy (FTIR-UATR). Seedlings of approximately 30 cm height were transferred in pots with 3 L of soil. The group of seedlings was separated into 5 different triplicate treatments according to the amount of hydrogel, as follows: H1 (25%), H2 (20%), H3 (15%), H4 (10%) and S (control without hydrogel). The applied hydrogel was mixed homogeneously with the soil. All treatments were irrigated with 40 mL of water. FTIR spectra were obtained from fresh leaves collected during 13 months of monitoring. The correlation of the hydroxyl (water) band with the main biomolecules between treatments with the control was evaluated using the Mann-Whitney test (p<0.05). The biomolecule bands were subjected to principal component analysis (PCA) and hierarchical clustering analysis (HCA). The results indicate a significant correlation of the water band with the lipid, hemicellulose, cell wall and starch components in the species. The use of hydrogel resulted in a significant difference in the water absorption band in relation to the control group through the Mann-Whitney test and in biomolecules as the HCA and PCA analysis suggested. The best development was observed in groups H4 (10%), H2 (20%) and H3 (15%). The use of hydrogel positively influences the biomolecular development of the Rapanea ferruginea and monitoring is viable by FTIR.

The effect of thermoforming on the tear strength of ethylene vinyl acetate (EVA) mouthguard material (Bioplast®) has not been widely investigated. The present study compared the tear strengths of non-processed and processed EVA specimens in various thicknesses. Two groups of EVA sheet (non-processed and processed) in three different thicknesses of 3, 4 and 5 mm were used in specimen fabrication. The processed EVA sheets were achieved by forming the EVA sheet on the cylindrical stone model with the pressure-molding device (Biostar®). Twelve of tear strength specimens of non-processed and processed group in each thickness were prepared following the modified ASTM D 624-00 guideline. The tear strength test was conducted using universal testing machine (Lloyd® 1K series) with the speed of 500 mm/min. The mean thickness and tear strength of the non-processed and processed specimens in each thickness were compared using independent T-test. The differences in the mean tear strength for each thickness of non-processed and process specimens were determined using one-way ANOVA. The mean tear strength and mean thickness of processed EVA specimens was significantly lower than the non-processed EVA specimens for every thickness (P ≤ 0.05). There was no significant difference in the mean tear strength of EVA specimens among each thickness in both non-processed and processed groups. It can be concluded that the thermoforming process has the significant effect on the tear strength of the EVA mouthguard material formed by pressure molding device in every thicknesses. The tear strength of processed specimens were significant lower than the non-processed. Thus, it is more relevant for testing properties of the processed mouthguard material that the mouthguard material before processing.

Abstract Abstract 4406 Methods of quantification of foetal red cell in maternal blood samples are important to ensure the correct administration of prophylactic anti-D to prevent sensitisation of the mother which may result in haemolytic disease of the newborn and foetus in subsequent pregnancies. We aimed to assess the accuracy of 3 methods: a gel card technique using anti-D and 2 acid-elution techniques, foetal cell detection kit (FCD, Inverclyde Biologicals Lanarkshire, Scotland) and a kit from Clin-Tech Limited (Guildford, England) based on the Kleihauer-Betke foetal stain technique (KBT), to quantifiy foetal red cells in maternal samples. The sensitivity of the gel method was also assessed. A total of 63 maternal blood samples and 30 man-made control blood samples were analysed, with only 57 maternal samples confirmed to be Rh D negative. Rh D positive samples were excluded. All samples were run concurrently with the 3 methods, according to manufacturers’ instructions. Mann Whitney test was used to compare the results. The gel technique was recorded in terms of grading of agglutination while the acid-elution kits were recorded by degree of FMH (mL). Column agglutination was also used to assess sensitivity. Results showed only 3 maternal samples were positive for FMH using the acid-elution method but not the gel technique. Statistically there was no significant difference between the techniques (Mann-Whitney test). Sensitivity of the gel method showed that it has the ability to detected FMH of more than 3mL whilst the 2 kits were able to detect FMH of 1mL. The study showed that gel technique required little skill to perform but it was not considered suitable for accurate quantification of FMH and consequently for the correct administration of prophylactic anti-D. The foetal cell detection kit (Inverclyde Biologicals) showed a similar ability to detect and quantify FMH when compared to the Kleihauer –Betke kit (Clin-Tech) with better overall staining intensity. The Kleihauer-Betke test from Clin-Tech and the foetal cell detection kit from Inverclyde Biologicals showed no significant difference (p = 0.98), thus there is no statistical significant difference between the 2 methods. However, the sensitivity of the column agglutination method was lower, as significant agglutination could only be observed with FMH of more than 3mL. The expected values were plotted based on Gomez-Arbones et al (2002), who cited significant agglutination seen when FMH is 0.1% or about 2.5mL. Sensitivity was found to be less than expected as a higher amount of bleed is required to observed significant agglutination. The FMH sample representing 1–6mL was repeated and similar findings were recorded, as significant agglutination was only observed when FMH was 4mL. The column agglutination method is not suitable as a quantitative measurement of FMH as it only allows qualitative analysis, thus if it is incorporated into a clinical setting, it must be accompanied by a quantitative test. The foetal cell detection kit has similar staining capabilities to detect foetal cells and compared to Clin-Tech was easier to use as there is no need to prepare eluting solution unlike the latter. However, fixing solution was not provided and hence need to be prepared. Results showed that only 3 maternal samples were positive for the presence of FMH and thus using a semi-quatitative acid-elution technique should be sufficient in FMH quantification unless FMH using the acid-elution technique exceeds 2mL, as recommende,d by the BCSH guidelines (2009), then the sample should be analysed using flow cytometry.

The respon­dent consisted of 60 elementary school students, which 30 of them classified as normal group and the rest of them belong to the goiter group. The two sample groups were analyzing by the t-test and Mann Whitney test. The correlation variables were analyzed by the Spearman test. There were significant difference between the income on the normal group and the goiter group; the normal group had higher income than the rest. There were significant difference between the adequacy level of energy on the normal group (73.5%) and the goiter group (55.8%) and the average of the variety of goitrogenic food consumption. The Mann Whitney test showed there were also significant differences for the quality of salt. There were significant correlations between mother knowledge about IDD with the adequacy of iodium, and between the cases of goiter with the quality of salt consumed by the family. Intensive nutrition education of IDD is needed to improve the nutrition knowledge of the mothers, as well as the availability of the accessible iodized salt.</span></p>
