    Learning transfer is the ultimate goal of any training programme. The new Malaysian skills training is based on the dual learning principle in which trainees alternate between attending theoretical classes in the skills training institute and receiving on�the-job training at worksite. This new paradigm of skills training is better known as National Dual Training System (NDTS). The main problem is that there were complaints from the employers that the competencies of the output of the skills training in Malaysia are of poor quality. This was due to low absorption of learning transfer performance from training places to workplace. Apart from that there were little studies related to the effectiveness of learning transfer due to there is no acceptable way and mean to measure the learning transfer. The aim of this study was to ascertain on whether the effectiveness of learning transfer did occurred in the automotive mechatronics of NDTS programme. The research focus area is the Mechatronics Automotive course. A longitudinal study method was employed as the research methodology. The participants of this research were the trainees and coaches from NDTS Mechatronics Automotive course. The study utilised the self�administered questionnaire, semi-structured interview, focus group and case study. Measuring 16 factors of the Learning Transfer System Inventory (LTSI) plus 3 factors derived from literature review and expert group discussion enable the researcher to determine the relationship between the learning transfer factors. It was found that NDTS training programme appears to have facilitated the positive transfer and near transfer from training situation to workplace environment. The findings of multiple regressions result suggest that the predictive variables explained 43.9% variance that has significance effect on the effectiveness of learning transfer. Apparently, the most influential dimensions of the effectiveness of learning transfer in NDTS were revealed as the course content, training delivery and working tasks. Interestingly, result indicated that the effectiveness of learning transfer in NDTS had occurred by the overall framework accuracy percentage of 79.2%. Therefore, the emerging effectiveness of learning transfer framework of NDTS in Malaysia is propose

    Kajian ini tertumpu kepada fabrikasi dan perincian ke atas komposit sandwic berpermukaan komposit gentian kaca dan berteras busa poliuretana yang diperkuat gentian sabut kelapa. Objektif utama kajian ini adalah mengkaji sifat – sifat fizikal dan mekanikal komposit sandwic dan menjelaskan kesan penggunaan gentian sabut kelapa keatas busa poliuretana dan panel komposit sandwic. Panel komposit sandwic terdiri dari dua bahagian, iaitu permukaan komposit gentian kaca yang dihasilkan melalui proses pengacuanan tekanan dan teras busa poliuretana yang dihasilkan melalui kaedah pengacuanan berputar. Kedua – dua bahagian ini disatukan menggunakan perekat epoksi pada tekanan 100 KPa. Gentian sabut kelapa digunakan untuk memperkuat busa poliuretana yang akan digunakan sebagai teras komposit sandwich. Peratusan berat gentian sabut kelapa yang digunakan adalah daripada 5%berat sehingga 20 %berat. Dari kajian yang dijalankan, didapati bahawa penggunaan gentian sabut kelapa telah meningkatkan prestasi sifat teras poliuretana dan komposit sandwic. Sifat – sifat fizikal dan mekanikal teras busa poliuretana dan komposit sandwic mencapai peningkatan optimum pada 5 %berat gentian sabut kelapa. Walaubagaimanapun sumbangan gentian sabut kelapa terhadap peningkatan prestasi hanya terhad pada 5 %berat kerana prestasi sifat mekanikal bahan menurun apabila melepasi komposisi ini. Ketumpatan komposit sandwic menurun sebanyak 32.41% pada komposisi 5 %berat gentian sabut kelapa yang mana mempunyai ketumpatan yang rendah dan menyumbang kepada penghasilan panel bahan yang ringan. Daya maksimum, tegasan ricih, dan modulus bagi komposit sandwic menunjukkan peningkatan masing – masing sebanyak 12.69%, 29.46% dan 12.97% pada peratusan gentian sabut kelapa 5 %berat. Ini menunjukkan bahawa sifat – sifat komposit sandwic dapat dipertingkatkan dengan peranan penguat didalam busa poliuretana yang menahan tegasan ricih secara melintang

    The reuse and recycling of waste materials from construction and demolition waste is one of the new concepts for brick manufacturing production. Construction and demolition debris refers to waste materials that result from the construction, renovation and demolition of buildings. Bricks are an important material for developing areas where manufacturers find it difficult to locate adequate sources due to the shortage of natural aggregate supply. Construction waste can be recycled to replace naturals resource or other competitive materials. This study aims to establish the sustainable properties for composite bricks using Recycle Concrete Aggregate (RCA) and Polyethylene Terephthalate (PET) waste bottles as sand aggregate replacement. RCA was obtained from crushed laboratory concrete cubes while PET bottles were collected around UTHM and Parit Raja areas. The objectives of this study are to determine the optimum cement-sand ratio (1:5, 1:6 and 1:7) for composite brick through density, compressive strength and water absorption tests, to investigate the mechanical properties and durability of composite sand cement bricks through shrinkage and carbonation tests, and to identify the optimum percentages of RCA and PET as sand aggregate replacement in composite bricks. For this study, the brick specimens were prepared using 25%, 50% and 75% of RCA and 1.0%, 1.5%, 2.0% and 2.5% of PET by volume of natural sand with a water-cement ratio of 0.6. The size of the RCA used measured less than 5 mm. Moreover, the size of the sieved waste PET granules was between 0.1 to 5 mm which made it physically similar to the size of fine aggregates. The bricks were cast in moulds measuring 215 mm in length, 103 mm in width, and 65 mm in depth. Three types of sand-cement ratios were used, namely 1:5, 1:6 and 1:7. The first stage of the study was the determination of the best sand-cement ratio through density, water absorption and compressive strength tests. The next stage was the determination of the optimum percentages of RCA and PET according to the shrinkage and carbonation tests. The overall results revealed that the best cement-sand ratio was 1:6. The density test indicates that the average density of composite bricks is lower compared to that of control bricks. The cement-sand ratio of 1:6 was the optimum value for all sample bricks. In addition, the percentage of water absorption for composite bricks was found to be satisfactory. It can be concluded that the optimal replacement of RCA and PET was R25P1 with a cement-sand ratio of 1:6 as it achieved the lowest values during the drying shrinkage and carbonation tests

    A comparative study of different induction techniques (Propofol-Placebo, Propofol-Ephedrine and Propofol- Placebo-Crystalloid) on intubating conditions after rocuronium administration

    This was a prospective randomized double blind controlled study to compare intubating conditions at 60 seconds with rocuronium 0.6 mg/kg by using three different induction techniques: propofol-placebo (PP), propofol-ephedrine (PE) and propofol-placebocrystalloid (PC). Ninety patients were included and randomly allocated to receive one of the three combinations. The patients were induced using fentanyl 2 μg/kg, followed by propofol 2.5 mg/kg with normal saline as placebo (Group PP and Group PC) or ephedrine 70 μg/kg (Group PE) given over 30 seconds. Subsequently, rocuronium 0.6 mg/kg was given over five seconds and endotracheal intubations were performed 60 seconds later. Intubating conditions were clinically acceptable in all patients except in four patients in PP group, who had poor intubating conditions. The proportion of excellent intubating conditions was significantly highest in Group PE (94%) followed by Group PC (81%) and lowest in Group PP (50%). In conclusion, induction with propofol-ephedrine and propofol-placebo-crystalloid combinations provided significantly better intubating conditions than propofol alone, when rocuronium 0.6 mg/kg was used for intubation at 60 second

    The Tsallis Distribution at Large Transverse Momenta

    Get PDF
    Fits to the transverse momentum distributions of charged particles produced in p - p collisions at LHC energies based on the Tsallis distribution have been shown to work over 14 orders of magnitude. Two versions of the Tsallis distribution are compared and discussed, the thermodynamically consistent version leads to a temperature of T = 74 +/- 13 MeV at the highest beam energy, a result which is in agreement with previous analyses done with lower transverse momentum data.Comment: 5 pages, 2 figure
