The Effects of Different IBA Concentrations, Light Regimes of in Vitro Rooting and Acclimatization of Invitro Teak (Tectona Grandis L.F) Plantlets

The effect of different IBA concentrations, two light regimes of in vitro rooting and acclimatization on in vitro teak ( Tectona grandis L.t) was investigated. The experiments followed a Completely Randomized Design (CRD) involving six concentrations of IBA (0mg/l, 0.5mg/, 1.0mg/l, 2.0mg/l, 3.0mg/l and 5.0mg/l) and two light regimes with 15 replicates each. The in vitro rooting experiments showed that shoots cultures in White medium supplemented with 2.0mg/l and 5 .0mgll IBA produced the best results in terms of mean number of root (6.33=6 and 7.66=8) and mean root length (1l.82mm and 8mm) respectively. In vitro shootlets incubated in the dark exhibited earlier root initiation by five days compared to those incubated in the light. Generally, shoots incubated in the light produced significantly higher mean number of roots (2.3) and mean root length (15.5 mm and 4.5 mm) when supplemented with low concentrations of 0.5mg/l and 1.0mg/l IBA. Conversely when shoots were incubated in the dark, higher mean root length of (14.0mm and 8.8mm) and mean number of root (7.5=8 and 3.3=3 ) were produced when being supplemented with higher concentrations of 2.0mg/l and 3 .0mg/l respectively. Chiefly 2.0mg/l IBA was found to be optimum for rooting of teak as it recorded high mean number of root (6.3=6 and 7.5=8) and mean root length (11.8mm and 1 4.0mm) regardless of light regime. The higher survival percentage of 80% was recorded for plantlet grown in "jiffy-7" but only 40 % survived in the autoclaved soil after one week. However the plantlets failed to continue to survive after the second week due to unforeseen technical error such as a faulty growth chamber. The present result substantiates the requirements of IBA to promote the in vitro rooting of teak shootlets and dark incubation to accelerate rhizogenesis

Mobile Learning Model for Children with Special Learning Needs

The mobile learning developed for children with special learning needs have limited users even within the same learning disability because severity in learning disability varies greatly even within a specific learning disability. Mobile learning developed for these children currently uses the same model used by any mobile application development where it caters for the masses rather than focusing on personalisation. The objective of this paper is to propose a mobile learning model for children with special learning needs, named APIE. ADDIE model is a generic instructional system design model that consists of processes: Analysis, Design, Develop, Implement and Evaluate. APIE is a modification from the ADDIE model, which makes APIE a mobile learning application development model. APIE iterates the design and develop processes under the Personalisation stage to explore the most suitable way for customisation for individual learning. APIE is applied to the development of a mobile learning for Dyslexic Children to assist the children to read and spell. Through APIE, a mobile learning application, DysleRead is produced. DysleRead integrates two classroom approaches: sight word and phonic where teachers can set and monitor individual learning needs of the children. The teachers find DysleRead helpful to teach the children. This shows that the mobile learning application produced using APIE meets the objective to cater for personalisation within a specific learning need without undermining the role of the teachers. Hypothetically, APIE model is applicable to other special learning needs to

Association of PCSK9 g.24382G > A with Increased Homocysteine Level among Bidayuh Ethnic Group in Sarawak Population

Objective: To determine the polymorphic allele and genotype frequencies of Proprotein Convertase Subtilisin/Kexin type 9 PCSK9 g.24382G > A. It aimed to elucidate the association of the polymorphic allele and genotypes with clinical profiles such as total cholesterol (TC), high- density lipoprotein (HDL), low- density lipoprotein (LDL) and homocysteine level in the Bidayuh ethnic group in Sarawak. Material and Methods: One hundred and thirty-nine (139) individuals from the Bidayuh ethnic group in Sarawak participated as study subjects. The Allele Specific PCR (AS-PCR) was used in the genotyping of PCSK9 g.24382G > A to detect the selected SNPs variant (Polymorphisms). Association of genotype frequencies with clinical profile was calculated using One Way ANOVA. As for the association of allele frequencies with clinical profile, Independent Sample T test was used. Results: Heterozygous genotype was statistically higher in normal level of total cholesterol level, LDL and homocysteine level whereas high level of total cholesterol and HDL ratio was statistically higher in variant genotype compared to homozygous genotype (p A show that it is significantly associated with high homocysteine level, F (1,137) = 5.018 (p = 0.027). Conclusion: Our results showed that the genetic diversity of PCSK9 gene influences the susceptibility to increased level of homocysteine in the Malaysian population and also support the involvement of LDLR mediated pathways in the process of Familial Hypercholesterolemia

Effectiveness of Objective Structured Practical Examination (OSPE) as a Tool for Formative Assessment of Practical and Experimental Skill for Pre-University Students in Biology Course

In many science courses or subjects, lectures (theory) and practical (hands-on) are integrated with the view that theory can be explained in the lecture and then applied and tested in the practical class (Whitworth & Wright, 2015). Similarly, in the Biology course for Centre for Pre- University Studies, Universiti Malaysia Sarawak, a lecture on Introduction to Laboratory Instrumentation was conducted. Meanwhile, the practical application and demonstration for this topic were also carried out. The objectives for this practical are to describe the usage and to define the functions of basic laboratory equipment and apparatus as well as to demonstrate the correct way of handling basic laboratory equipment and apparatus

PPPU BULETIN : Special Edition Asasi Eco Ambassador

This publication will both encourage the students to continue spending the commitment of academic production and inspire juniors to follow their example. As in the past years, the write-up has demonstrated the wide variations of biodiversity, ecology, and environment study in various location of national park in Kuching, however, in this issue, you will find the study conducted within the campus area. Nevertheless, the study as far-ranging and divergent as eco-based potential plant for commercial uses, documentation of water quality, rapid wildlife survey, observation of plant-animal interaction, plant-plant interaction, fungi, gymnosperms, angiosperms, pteridophytes, Nepenthes, horticulture plant, palm species, medicinal plants, potential threat to ecosystem, and peat-swamp ecosystem. In a word, there is something for all the students
