Title : Harnessing Microbes for Sustainable Environment
Harnessing microbes for sustainable environment explores the potential applications of microorganisms in maintaining our ecosystem.For the management and recycling of materials and wastes,microorganisms play critical roles; successful biological treatment however,depends on the development and maintenance of highly acclimatised, mixed microbial population in the system.Their abilities to survive in waste-water containing toxic organic pollutants can be utilized for the breakdown of highly complex organic compounds into simpler degradable compounds or even mineralization for safety discharge of the effluent.Versatile groups of microorganisms were selected and applied as free-floating,biofilms and biogranules for the treatment process. Intensive research on the biological treatment process ed to development of highly adaptable group of bacteria able to treat real waste-water that is highly coloured,recalcitrant organic pollutant and toxic heavy metals.The diversity of their metabolic activities can be also be utilized to produce renewable energy such as biohydrogen,biolelectricity,biofuel and value-added renewable materials such a bacterials nanocellulose and bioplastics. Bioinformatics was further studied to intensify fundamentals research on the biocatalysts (enzymes) and genes having major roles in the treatment process.Having developed effective treatment process will contribute significantly to an overall treatment process that is eco-friendly,innovative and sustainable.

Title : Corporate Property Asset Strategy of Public Sector : Unleashing the
Tangible and Intangible Benefits
Corporate Public Property Assets (CPPA) constitute all government property
ownership viz. land and buildings in use to provide service delivery to the public
accordingly. Decisions of CPPA include site selection, building and facility
design and space utilisation, inevitably affect government’s operations and future
operation expenditure. Major cuts in budget allocation by the government calls for
the government agencies (GA) to initiate revenue generation to cover operational
expenses. At the same time, being required to provide the most suitable property
assets in support of core service delivery requirements. The fundamental issue in
effective CPPA strategy is lacking of knowledge of how the CPPA function is
addressed in the GA community to assess the relative CPPA performance in
supporting the agency’s performance. This paper unleashes the tangible and
intangible benefits of CPPA to the GA in supporting the highest quality of service
delivery to the public. Four main components of CPPA strategy are strategic
thinking, sophistication of implementation, performance evaluation and reporting
prepared for continuous improvement. CPPA strategy must be systematically
addressed and implemented in realizing income optimization, cost savings and
better value.

Title : Trends in Process Tomography
Tomography system is one of the methods that had been used to construct cross-sectional image from data obtained by the system. Basics concept of tomography is to determine the distributions of materials by obtained the data using sensors that distributed around the periphery of pipeline. Tomographic imaging system designed to analyze the structure and compositions of objects by examining them with waves or radiation and by calculating virtual cross sections through them.Tomographic sensing instrumentation also helps us to visualise the internal characteristics such as to measure the concentration, velocity, mass flow rate, and particle sizes distribution. The development of tomography system divides into three segments where there are sensors, data acquisition system, and software. Tomography system has two main components which is hardware part and software part. For hardware its contain sensors, signal or data control, while software contain signal reconstruction display. For hardware, the right choice of sensors is needed because sensors is the main part in tomography system and it is chosen based on the types of particles or objects that we want to measure whether it is liquid, gas, or multiphase mixture. Sensors perform indirect measurement of the image by detecting the radiation with which the object examined. The signals from sensor usually being amplified, filtered, and multiplex before it send the data to the computer. In this presentation we will discuss the trends of process tomography included the sensors used.
