Parametric Studies on Composite Bridges: Bending Moment Analysis

The research is about parametric studies on composite bridge and integral composite bridge that are designed by using Eurocodes. Besides, the research will also show the comparison between BS and Eurocodes by using composite bridge as example. In Malaysia today, most engineering firms are still using British Standards as their code of practice whereas worldwide firm may have shifted to Eurocodes. On the other hand, bridges in Malaysia are mostly purely composite types which needed much maintenance cost if compared to integral composite bridge. The research will show all the methods used to design both types of bridges with two different codes. Specific graphs, diagrams and flow charts are used to help readers get better understanding when reading through. Design calculation is done by using manual calculation, working example and also spreadsheet. For software modeling, CSI Bridge 2014 and Oasys GSA have been used. These software helps on designing of composite bridges on Eurocodes which were used for comparison. Results of the research show the live loading of Eurocodes bridge design is lesser than the British Standard bridge design. Results also show that with different parameters used on the bridge, different value of stresses will acting on the bridge structures. Future recommendations have also been show in the later part of this report

Comparing Delinquents And Non Delinquent Siblings With Regard To Social

According to Kornhauser (1978), all the delinquency theories originated from two main delinquency models that are the Strain Model and the Control Model.The Strain Theory suggests that felt strain resulting from frustrated needs or wants, acts as motivation for deviant behaviour. According to the Social Control Theory, social resources resulting from positive bonding with significant others such as parents, conventional peer-groups and teachers in school, act as restraints on deviant behaviour

Evaluation of total phenolic content, antioxidant activities and sugarcontent of fresh mixed fruit and vegetables juices

The notion of fruit and vegetables (FV) in preventing chronic diseases has long been discerned. To meet the recommended FV intake, FV juices have emerged as a convenient and healthy choice. Mixed fruit and vegetable juices (MFVJ) cater the blend of desirable flavor and taste of consumers. This study was carried out to determine the total phenolic content (TPC), antioxidant activities and sugar content of selected MFVJ. Folin-Ciocalteu assay was employed to quantify TPC, whereas DPPH and FRAP assays were used to evaluate the antioxidant activities of MFVJ. The sugar content was determined using phenol-sulfuric acid method. MFVJ extracted from bitter gourd, green apple and orange (BGO) had the highest TPC content (76.4 ± 4.2 mg GAE/100 ml). Celery and green apple (CG) juice showed the highest DPPH value (522.3 ± 7.6 mg TE/100 ml) whereas carrot and starfruit (AS) juice have the highest FRAP value (419.6 ± 21.6 mg TE/100 ml). The sugar content of MFVJ was within the range of 5.7-13.3 g/100 ml. MFVJ can be considered as healthy beverages with considerable amounts of phenolic compounds and low sugar content. This study provides some useful reference for consumers who consume juices with combinations of FV. Future studies need to discover more combinations of FV juices, providing more data pertaining to MFVJ. Identification of individual phenolic compounds should also be part of future research using various instrumental analyses

Culture of Papaya Explant in Solid - Liquid Media Sequence as a Rapid Method for Producing Multiple Shoots

Culturing papaya axillary buds obtained from mature field-grown trees on solid MS + 0.1 mg/l BA + 500 mg/ l casein hydrolysate + 0.38 mg/l riboflavin produced less than 2 shoots per explant over a period of2 to 18 weeks. However, 82 times more shoots were produced when the explants were cultured on solid medium for 10 weeks followed by another 10 weeks in liquid medium

Effects of different cooking methods on isoflavone content in Malaysian soy-based dishes

Soy-based products are one of famous raw ingredients used in the preparation of Asian cuisines. These soy-based products are good source of isoflavones. This study was carried out to observe the effects of different cooking methods on isoflavone content in soy-based products. A total of eight Malaysian dishes prepared using soy-based products with different cooking methods was selected as samples for this study. Daidzein and genestein contents in raw and cooked soy-based products were both quantified using high performance liquid chromatography (HPLC). The results showed that dishes containing tempe as ingredients had significantly higher (p0.05) in this study

The Effects of Conceptual and Logical Interfaces On Visual Query Performance of End Users

To the end users, the interface is the system. A better interface not only facilitates end user interaction with the database, it also enables them to formulate queries more efficiently and effectively. Two of the most important user-database interfaces are the conceptual and logical interfaces. With the conceptual interface, the user communicates with the database system in terms of entities, objects and relationships. On the other hand, the current user-database interaction is mainly based on the logical interface where the user expresses the queries in terms of relations and join operations. Because the concepts at the logical interface are abstract and convoluted to ordinary users, many researchers argue that end users will be better off with the conceptual interface. This research will test this claim by comparing the effects of coneeptual and logical interfaces on the visual query performance of end users. The experimental study involves three tests: an initial test, a retention test and a relearning test. This allows us to assess the learning effect over time. The results show that users of the conceptual interface achieve higher accuracy, are more confident in their answers, and spend less time on the queries than users of the logical interface in all three tests

Comparison of Total Phenolic Contents (TPC) and antioxidant activities of fresh fruit juices, commercial 100% fruit juices and fruit drinks

There is an increasing trend of fruit juice consumption due to increasing reported health benefits of antioxidant content present in fruit juices. The aim of this study was to compare the total phenolic contents (TPC) and antioxidant activities of fresh fruit juices, commercial 100% fruit juices and fruit drinks. Seven types of freshly blended fruit juices and their commercial counterparts were selected. Folin-Ciocalteu method was used to determine the total phenolic content, whilst ferric reducing antioxidant power (FRAP) and 2,2-diphenyl-1-picrylhydrazyl (DPPH) assays were performed to evaluate the antioxidant activities of fruit juices. The TPC contents of fresh fruit juices, commercial 100% fruit juices and fruit drinks were at the ranges of 13.38-80.40, 21.65-130.39 and 3.32-45.10 mg GAE/100 mL, respectively. Both fresh guava juice and commercial guava drinks have exhibited the highest antioxidant activities in DPPH assay (205.71-770.12 μmol TE/100 mL) and FRAP assay (320.80-843.13 μmol TE/100 mL). Pomegranate juices demonstrated the highest antioxidant activities among commercial 100% fruit juices with DPPH and FRAP values of 2705.01 and 2953.85 μmol TE/100 mL, respectively. Fruits drinks group had the lowest TPC and antioxidant activities for all types of fruits. TPC was significantly correlated (p0.05) was found between these two groups. Commercial fruit drinks in this study were not good source of antioxidants. These findings provide some useful information especially for ageing population in choosing healthy fruit juice or drinks for their health maintenance purposes
