Training transfer is refers to the trainees ability to accept what has been taught in the course of training and transfer them to actual working situation and be able to retain it for a certain period of time. The evaluation is to identify the relationship between trainee characteristics, training design and work environment towards transfer of training among employee. The findings of the study suggest trainee characteristics, training design and work environment play significant roles in the training transfer. We then offer research and suggest for future research directions.

Past research had demonstrated that congruence between store image and self-image is positively related to consumer behaviour such as patronage, store choice, store preference, and also store loyalty. With the concept of corporate social responsibility (CSR), specifically, the green environment having gained a legitimate place in retail strategy, the need to understand the function of this concept in self-congruity model of retail industry has become imperative. Despite of much attention has been given on this concept, few, if any, has reported its role in the self-congruity model. Thus, this study attempts to fill the void by developing a model which examines the role of green environment image of the retail store in self-congruity theory in influencing consumer behaviour. It attempts to test the relationship between self-congruity, and green environment image of a retail store and also to examine the role of green environment image in the self-congruity model in influencing store loyalty. Based on the study of consumers of casual apparel, it was found that self-congruity, specifically actual self-image and ideal self-congruity as well as green environment image have positive effects on store loyalty. Importantly, green environment image has shown a biasing effect on the relationship between actual and ideal self-congruity and store loyalty. As a result, this study provides empirical support for the new framework on the role of green environment image in the self-congruity model. The result also provides important findings to the researchers and practitioners as well as implications for future research directions and management of retail industry.

The search for alternative fuels to substitute for fossil fuels with competitive price range is an ongoing subject for research. There are several proposed feedstock, namely refined palm oil, crude palm oil, waste cooking oil and currently, palm fatty acid distillate. Refined and crude oils were debatable to be used as the main uses for both oils were for edible purposes. Waste cooking oil (WCO) is the cheapest source and can reduce problems on waste oil disposal whereas palm fatty acid distillate (PFAD) is a byproduct from palm oil refining, therefore can be a readily available feedstock. However, due to the high free fatty acids (FFAs) content of waste and palm fatty acid distillate, these sources cannot be converted directly to biodiesel via alkaline transesterification. In this study, two step process, which combined acidic and alkaline process were used to convert waste cooking oil and palm fatty acid distillate to biodiesel. The parameter investigated was the catalyst percentage, which was varied from 1 wt% to 5 wt%. For waste cooking oil, the yield of methyl esters was constant after using 4 wt% of catalyst, with the highest yield of 90 wt%. For palm fatty acid distillate, the yield of methyl esters was also constant from 1 wt% of catalyst, thus this amount of catalyst was already sufficient to produce a high yield of methyl ester, which was as high as 95 wt%. The methyl ester composition for both sources composed mainly of stearate and palmitate. The amount of palmitate increased whereas stearate decreased with increasing amount of catalyst used.

We investigate the effect of light pollution as the important considerations that limits the quality of the sky brightness for the astronomical purpose. Selected sites that covered: Klang, Selangor, Merlimau Melaka, Ipoh, Perak ad Kuala Lipis, Pahang, Malaysia have been chosen in order to investigate the visual estimation magnitude for observing visible stars. The results also based on Bortle scale theory provides glimpses of potential quality of night sky quality that is currently lost in most urban area in Malaysia. From the results, Kuala Lipis, Pahang is the best candidate site for astronomical purpose with the range of magnitude from 20.3 till 21.5 magnitudes per arc second. Some recommendation for a better solution will also be discussed.

Modeling and simulation of CO2 capture from flue gases of coal fired power plant at high temperature are presented. The work employed a 19% potassium and 1% sodium hydrotalcite adsorbent, for which CO2 capacities in excess 0.84 mol/kg were measured at temperature of 575 K. Elution profiles from a pressure swing adsorption (PSA) unit also enabled analysis of adsorption and desorption process. A cyclic and multibed process for the continuous capture of CO2 was proposed. A mathematical model for the CO2−19% potassium and 1% sodium hydrotalcite adsorbent system, based on measured equilibria and kinetic data, was used for the assessment of the process in terms of CO2 product purity and recovery.

This paper appraises the thermal comfort condition of in air conditioned learning environment of the new learning campus in Universiti Teknologi MARA, Puncak Alam. The physical measurement and survey questionnaires have been thoroughly measured among the occupants (235 respondents) in four air conditioned classrooms along with four lecture theatres. The result shows relative humidity and air velocity are within the recommended limit while operative temperature for both classrooms and lecture theatres were below recommended limit. The calculated Prediction Mean Vote (PMV) — Predicted Percentage Dissatisfied (PPD) indices computed merely 29% has shown dissatisfaction towards learning environments. In addition, computed Thermal Sensation Vote (TSV) for classroom divulges that people remarked the learning environment for classroom and lecture theatre to be ‘slightly cool’. However, the mean value of thermal comfort based on Predictive Mean Vote (PMV) for classroom was −0.05, which indicate ‘neutral’ condition, whereas PMV value for lecture theatres was −0.62 which is ‘slightly cool’. Therefore, those findings show calculated thermal states have not necessarily correlate to occupant's desired thermal state.

The effect of nutrient concentrations and pre-infestation of brinjal (Solanum melongena) plant with pest species on population of whitefly (Aleyrodidae; Hemiptera) was investigated over a cropping period. Three dosages of nutrients (fertilizer) were applied on brinjal seedlings; N1–50ppm, N2–150ppm and N3–300ppm respectively. The brinjal seedlings were pre-infested with two pests, whitefly and aphid. The control plants were non-infested with any pest. Populations of whitefly were higher following increasing levels of nutrients in non-infested plants. No significant variation on mean population densities were observed among the sampling times. In the pre-infested brinjal plants, the level of nutrients did not influence the abundance of whitefly population infesting brinjal plants. Lower whitefly populations were observed on whitefly pre-infested brinjal plants compared to aphid infested and non-infested plants. Pre-infested plants were suspected to induce productions of secondary metabolites as a chemical defence system thus lowering the number of whiteflies on them. Whitefly populations were found higher during early growth of brinjal plants due to high number of leaves and good plant growth. Considering other management technique in controlling whiteflies on brinjal such as appropriate nutrient supplement and good pest care during seedling stage was proposed.

This paper discussed the current status of a grid-connected photovoltaic (PV) system installed in Malaysia. There are 97 locations with capacity of array power, which is 857.92 kWp grid-connected PV systems are monitored by the Photovoltaic System Monitoring Centre (PVSMC), UiTM. Since monitoring the performances for grid-connected system, there are several sites had been detected facing problems involve technical problem like an inverter fault, sensor fault and environmental problem such as shading effect and lower energy. All the problem will be affected the PV system performances in terms of final yield and performance ratio thus it will be inclined the data availability problem. Furthermore, it could waste the energy produced by PV array and energy payback period. An established practical knowledge in designing a PV system need to be taken seriously in order to avoid improper design before installation to maximize the energy production. It is very important to structure proper design and sizing procedures, identify the factors which affect the performances and component sizing for PV system to optimize and utilize the energy production before any actual implementation of solar power energy system installed.

Preliminary thermogravimetric studies of Silantek coal (SL), Palm Kernel Shell (PKS), PKS char and their blends have been performed in a Thermogravimetry Analyser(TGA). PKS char were produced using microwave irradiation carbonization system at power of 300 Watt, with nitrogen flow rate of 150 mL/min for 30 minutes. Combustion tests of raw and blends samples were carried out in purified air atmosphere conditions at heating rates of 20 °C/min. The SL/ PKS and SL/ PKS char blends were prepared in the weight ratios of 80:20, 60:40, 50:50, 40:60 and 20:80. Derivative thermogravimetric (DTG) results which represent the decomposition of volatile matters and char showed that raw PKS has higher reactivity than SL during combustion process. The thermal profiles of the SL: PKS blends correlated with the percentage of PKS added in the blends, representing lack of synergic effect between both samples. SL and PKS char blends results in single evolution peak, indicated possibility to be used as alternative fuel for combustion. These findings may be useful for the power generation industry in the development of future co-firing plants using coal/ biomass; however, significant development work is required before large-scale implementation can be done.

These findings may be useful for the power generation industry in the development of future co-firing plants using coal/ biomass; however, significant development work is required before large-scale implementation can be done.","PeriodicalId":105476,"journal":{"name":"2011 3rd International Symposium & Exhibition in Sustainable Energy & Environment (ISESEE)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124408197","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
