The perceptions of KUIM’s (Kolej Universiti Islam Malaysia) first year undergraduates in learning English using ‘tell me more’ software

The use of technology in language learning has expanded rapidly worldwide during the last few decades. Studies on the effects of technology enhanced instruction on achievement and studies on students’ attitudes regarding learning with technology have also increasingly been reported (Salaberry, 2001). Technology includes computermediated communication via email, incorporated task-based Internet activities,interactive publisher-produced CD-ROM, interactive software, threaded discussions and many others. This paper focuses on the perceptions of students at Kolej Universiti Islam Malaysia (KUIM) towards learning English as a second language using ‘Tell Me More’ software. This software has been used in KUIM for many years and for the past few semesters, it has been made compulsory for all first year undergraduates to self-access the software for at least an hour per week. Various feedbacks were received but most of the responses were positive. Most of the respondents favoured learning English using the software, but they still preferred conventional classroom English lessons

Establishment of rainfall erosivity calendar at main cities of peninsular Malaysia / Nur Zarina Zakaria

Malaysia in its rapid growing of development is undergoing tremendous land use changes especially in the development of infrastructure. Although this activity forms an important role to the intergral part of the socio-economic advancement in the country, the unpleasant effects of land development, particularly soil erosion will certainly jeopardize its success. Soil erosion has become a very serious problem in Malaysia recently and it is one of the natural processes that occur on earth. With the accelerated land development both in public and commercial sectors, this problem will certainly persevere and deteriorate unless proper planning and management of land utilization is adopted at the early stage of any future land development. The fact that soil erosion continue to be an environmental problem and of significant impact in the country suggest that more definitive guidelines and stem monitoring of land development are required. Therefore. This research will focus on recognizing the rainfall induced erosion risk occurrence since rainfall is one of the significant factors is causing soil erosion that can leads to landslide to major cities in Peninsular Malaysia. Thus, evaluation of rainfall erosivity profile at the main cities of Peninsular Malaysia namely Alor Setar, Georgetown, Kuala Lumpur, Johor Bahru, Kuantan and Kuala Terengganu would be tangible contribution to the various states government in tackling problems to soil erosion issues. Research outcomes indicate that different cities reveals different results namely the monthly rainfall amount, erosion risk frequency, percentage of rainfall erosivity potential as well as the degree of values of rainfall erosivity. As in the case of the most risky months, months of October, November and December recorded the highest number of occurrence based on the accumulated degree of 7 days rainfall amount. Further results reveal that the most risky city with regards to rainfall erosivity corresponding to high, very high and critical degree 0f“ROSE” Index is Kuala Lumpur while the less risky city is Kuala Terengganu. The results indirectly confirm the severity of erosion induced erosion at Kuala Lumpur city based on historical records as well as the present scenario. This research is also useable in other areas in Malaysia in order to determine the risky and safest areas with regards to rainfall induced erosion which can leads to landslide

Analysis of major fragrant compounds from citrus grandis flowers extracts

Various sampling techniques such as hydrodistillation, Soxhlet extraction and solid phase micro extraction (SPME) were used to extract compounds, i.e. the active components attributed to fragrance of C. grandis flowers. Gas chromatograph mass spectrometry was then used to identify and quantify the active components obtained from the techniques. The results thus far showed that, buds and blossoms of this flower which possesses a strong floral-, jasmine- and orange-like aroma contain β-myrcene, limonene, ocimene, linalool and caryophyllene as the major compounds. In hydrodistillation technique the levels of ocimene and linalool detected in blossom were higher than in the bud at 7.37 and 15.93%, respectively, while in the bud, limonene was the highest, i.e. 4.57%. In Soxhlet extraction, however the bud was found to consist of limonene (27.25%), ocimene (5.55%) and linalool (2.97%). The performance of three available SPME fibers was compared to evaluate the recoveries of volatile compounds in C.grandis flowers and 100 μm polydimethylsiloxane was found to be the most effective

The Optimisation Of Growth Regulators, Precursors And Elicitors Supplementation For Maximum Limonene And Linalool Accumulation In Cell Cultures Of Citrus Grandis (L.) Osbeck

The study on Citrus grandis (L.) Osbeck encompasses tissue culture production and the extraction of limonene and linalool. The tissue culture methodology comprises of sterilisation, induction and maintenance of callus on media favouring cell growth, to favour production of limonene. Explants sterilisation attained high yields of sterile explants (~ 90%) in treatment with 20% Chlorox® (I% sodium hypochloride). Callus gro\\rth is favourable from explants originated from 5-week-old fruits and cultured on modified MS media with 510 mg/1 phosphate, 3 mg/1 each 2,4-D and kinetin and 0.2 mg/1 ABA. Limonene was first detected from 7- month-old callus up to 10-month-old cultures which yields the highest limonene concentration before slightly down at the 11th month. The amount of linalool extracted was highest from 7-month-old callus and decreased as the age of callus cultures increased. Media 6 with supplementation of 51 0 mg/1 phosphate, 0.2 mg/1 ABA and 3 mg/1 2,4-D and kinetin respectively, gave maximum concentration of limonene, which is 0.0031 mg/g fresh weight of callus. The effects of supplementation various concentrations of exogenous mevalonic acid (MY A) and linalool to C. grandis callus cultured at varying periods were studied. Callus grov,rth was found to be proportional to the concentrations of MY A and linalc~_ol especially during the first 6 weeks. Kajian ke atas Citrus grandis (L.) Osbeck melibatkan penghasilan kultur tisu dan pengekstrakan limonena dan linalool. Kaedah kultur tisu terdiri daripada pensterilan, induksi dan pengekalan kalus dalam media yang menyokong pertumbuhan sel, yang juga menyokong penghasilan limonena. Pertumbuhan kalus adalah paling sesuai menggunakan eksplan yang terdiri daripada buah yang berumur lima minggu yang dikultur dalam media MS yang diubahsuai dengan 510 mg/1 fosfat, 2,4-D dan kinetin yang masing-masing 3 mg/1 dan ABA sebanyak 0.2 mg/1. Limonena dikesan bermula pada kalus berumur 7 bulan sehingga bulan ke-1 0 yang memberikan penghasilan limonena yang tertinggi sebelum menurun sedikit pada bulan ke-11

Stakeholder engagement in waste management: understanding the process and its impact on accountability

This thesis examines the operationalisation of stakeholder engagement process in sustainable waste management setting. The study aims to establish role of stakeholder power in the prioritisation process and add to empirical understanding of the way engagement affect accountability, which evaluates both the `process', and the `outcome' of engagement. This research is based on a three mini cases of local government authorities, which involve in-depth interviews, observations and document analysis. A broader insights of the engagement process from several stakeholder groups, namely the residents, NGOs, councillors and private waste contractors, are considered and compared with managerial views, and several aspects of stakeholder engagement practices are analysed, including the mechanisms used as well as the challenges faced by the LGAs in engaging. In addition, the intentions behind engagement undertakings are analysed and evaluation of the effectiveness of stakeholder engagement practices are made. Drawing on stakeholder theory, the role of power is explored as a stakeholder attribute in determining salience and in the engagement process. Insights from the interviewees are analysed in relation to the extent of participation and perceived level of power held which are then used to map the extent of their involvement on the ladder of engagement. The findings indicate that power does play an important role in the engagement process. Managers also give greater consideration to those demonstrating certain extent of power i.e. the private waste contractor and councillors. It has also been proved that managers' perceptions of the levels of power held by stakeholders play a significant role in establishing their priorities and deciding between competing interests. The use of stakeholder engagement as a mechanism for accountability has led to the recognition of a deficiency underlying the many processes of engagement. The study also has identified an additional feature of accountability, namely the interactive nature of engagement, which is unrecognised in other established measures of accountability

Smart Trash Bin to Prevent Animal Disturbance Using Raspberry Pi and Deep Learning

A trash can is an indispensable component of human daily life. It is ubiquitous and extremely useful for keeping the city clean. However, littering is a frequent and widespread problem. Not only do humans litter, but so do animals, particularly monkeys. Animals are constantly searching for food, and when we discard our food waste, they are attracted and leave their natural habitats. Following that, the user may forget to lock the trash can, which may end up in the hands of the animal. With the aid of a deep learning system that detects and identifies human subjects, a smart trash bin with an autonomous locking mechanism will be used in this project to reduce animal disturbance. In this paper, Raspberry-Pi 4 module is being used. Moreover, this article describes a human subject identification method and its real-time displacement using the OpenCV library of programming roles, which is primarily aimed at Raspberry Pi with camera module. The smart trash bin system helps to reduce animal disturbance and minimise littering

Effect of pH and salt concentration on protein solubility of slaughtered and non-slaughtered broiler chicken meat

This study examined the influence of pH and salt concentration on the protein solubility of slaughtered and non-slaughtered broiler chicken meat. Three types of salt (NaCl, Na2SO4, and (NH4)2SO4), five different pH levels (5.0, 6.0, 7.0, 8.0 and 9.0) and five salt concentrations (0.4, 0.8, 1.2, 1.6, and 2.0 M) were examined. Each type of salt showed distinctive activities for slaughtered and non-slaughtered meat protein solubility. Soluble protein concentration increased as pH increased (p<0.05) from pH5.0 to 8.0 and decreased from pH8.0 to 9.0. It was also observed that protein solubility increased as the salt concentration increased. Protein solubility significantly increased (p<0.05) in the non-slaughtered meat compared to the slaughtered meat at pH8.0 for Na2SO4 at 1.2 M

INDUCTION OF CALLUS FORMATION FROM DIFFERENT PARTS OF Citrus grandis (OSBECK) FLOWERS

            The objectives of the present work were to study the capability of pomelo’s floral tissues to produce callus and to investigate the influence of plant growth regulators on callus induction and development. Various parts of flower namely petal, sepal, style, ovary, pistil and cup base were cultured onto Murashige and Skoog (MS) basal medium supplemented with different level of 2,4-dichlorophenoxyacetic acid (2,4-D), 6-benzylaminopurine (BAP) and 6-Furfurylaminopurine (kinetin). It was found that different part of flowers favored different level of hormone for callus induction. The highest formation of callus were obtained from petal and sepal cultured on MS media supplemented with 1.5 mg/l kinetin. For the style and pistil, 50 ± 2.3% of the explants had developed callus when cultured on MS media supplemented with 0.05 mg/l and 0.10 mg/l BAP respectively. On the other hand, sucrose agar (SA) media alone had managed to induce callus formation from almost every part of the flowers with a success rate between 7.69 ± 0.32 to 50 ± 3.18%. Callus formation was preferred from the uncut part of flowers as shown in the study on petal with percentage of formation was 14.6 ± 0.35%
