Abstract: Carbon dioxide (CO2) and other greenhouse gases (GHG) emissions, which cause global warming, have become a major worldwide concern with ten global ‘mega’ challenges that are currently impacting the planet in particular climate change, water, energy, and material resource scarcity. Increase in urbanization rate will continue to increase its need for natural resources, building materials, power and electricity, water, etc. that leads to bio-capacity deficit with a sharp increase in generation of ecological footprints. Power-generating plants running on fossil fuels have been identified as the main source of greenhouse gases (GHG). Approximately, 80% of the world primary energy consumption is still dependent on fossil fuels; thus, the substitution by renewable energy sources, in conjunction with other clean energy sources, appears to be the best and necessary alternative. There are many other sources of renewable energy such as solar, wind, and geothermal, but biomass have been receiving a lot of attention lately. Biomass has gained increased attention in the past decade because it does not only provide an effective option for the provision of energy services from a technical point of view, but also based on resources that can be utilized on a sustainable basis all around the globe. Another benefit of biomass utilization is that this resource can be converted to C3-C4 hydrocarbons and/or synthetic gas (H2 and CO).

Application of Taguchi Technique to Investigate the Effect of Process Parameters on Product Yield and Carbon Content in Empty Palm Oil Fruit Bunch Carbonization
M. Alfaresi,S. Yusup
Journal of Applied Sciences , 2010,
Abstract: Carbonization is an important process which is used in a number of industries where, raw material from coal or agricultural origin are treated to remove moisture, volatile matter or undesirable material to yield a charcoal like product which may be further processed to produce valuable products such as activated carbon. In the current study, selected carbonization parameters are studied to investigate their effect on product yield and carbon content. Empty Palm Fruit Bunch (EPFB) was selected as the process feedstock for its wide availability; being a byproduct from palm oil industry. The studied parameters are carbonization temperature, nitrogen flow rate and soaking time. Taguchi technique for design of experiments and offline process analysis/optimization was used to build the approach of experiments by utilizing a modified L9 orthogonal array. The significance of each parameter was calculated by analyzing the results statistically to obtain the signal to noise ratio for each run as well as each level of parameter. The results showed that temperature had the most significant effect over product yield followed by nitrogen flow rate. The soaking time effect was statistically lower than that of gas flow rate but quantitatively close in value. For the carbon content of the product, soaking time showed to have the most significant effect. Temperature effect was second while gas flow rate seems to have the least effect statistically and quantitatively. Proposed carbonization conditions based on the results obtained in the current study are temperature of 650°C, nitrogen flow rate of 0.6 L min-1 and 30 min soaking time which gave 60.4% carbon content and 26.7% product yield.

Journal of Software , 2010, DOI: 10.4304/jsw.5.1.44-53
Abstract: Mathematical expression recognition is an important problem about pattern recognition, because mathematical expression is an essential part of scientific literature. This paper focused on two aspects, first of all, About the recognition of on-line handwritten mathematical expressions, this paper elaborates the structural analysis strategy from the perspective of the general mathematical expression, we bring forward a feasible solution to the overall structural analysis by using some pretreatment methods, such as dominating relationships, hard-regulations, function merging, and so on. The results show that this method can overcome some shortcomings of traditional structure analysis methods, and also it can dispose some recognition errors that often appear in the space structure and logical structure of the on-line handwriting recognition system effectively, such as symbol overlapping and handshaking, complex layer structure, the table structure and so on. Secondly, on this basis, We have contrived an online handwriting recognizing system of mathematical expression based on an embedded equipment, which supports in the use of the languages of the minority, such as Uyghur and Kazakh languages .For the features of mathematical expression recognizing, and from the point of ensuring the system’s efficiency , this paper has constructed an embedded platform, on which the capability of the system has been tested, and it has compared the data gained from the test with those in PC , which offers a gist to improve the algorithm and perfect the system.

Abstract: Gene and protein expression by fibroblast-like synoviocytes in vitro was studied by quantitative Polymerase Chain Reaction (qPCR), ELISA and multiplex bead cytokine assays. Intracellular signaling pathway activation was determined by Western blot for phospho-kinases and the use of specific inhibitors.In combination, TGF-β and PDGF (2GF) synergistically augmented TNFα- or IL1β-induced matrix metalloproteinase 3 (MMP3), IL6, IL8, and macrophage inflammatory protein 1 alpha (MIP1α) secretion by FLS. Other FLS-derived mediators remained unaffected. Individually, neither growth factor significantly potentiated TNFα or IL1β-induced MMP3 secretion, and only slightly enhanced IL6. The effect of 2GF on TNFα-induced gene expression was transcriptionally mediated; blocked by imatinib mesylate; and occurred even if 2GF was added as much as four hours prior to TNFα. In addition, a 15-minute pulse of 2GF four hours prior to TNFα stimulation yielded a synergistic response. The extracellular-signal-regulated kinase (ERK) and phosphoinositide 3-kinase (PI3K) signaling pathways were induced for at least four hours by 2GF, as demonstrated by persistently upregulated levels of phospho-Akt and phospho-ERK. However, pharmacologic inhibitor studies demonstrated that the potentiating action of 2GF was dependent on PI3 kinase only, and not on ERK.The combination of PDGF and TGF-β dramatically potentiates FLS response to cytokines in a receptor-mediated and PI3 kinase-dependent fashion. These data suggest that 2GF contribute to synovitis by directing synovial fibroblasts toward a more aggressive phenotype in response to TNFα. Therefore, inhibition of growth factor signaling may constitute a complementary therapeutic approach to cytokine-targeted treatments for RA.Expression of the regulatory peptides, platelet-derived growth factor (PDGF) and transforming growth factor beta (TGF-β) are increased in synovial tissue and fluid of rheumatoid arthritis (RA) patients [1-4]. PDGF has been implicate

Abstract: Objectives: To evaluate effectiveness of an online training program in preparing health care students to address tobacco use with patients. Methods: The program was evaluated on knowledge, attitude, self-efficacy, intended behavior, and user satisfaction. Participants consisted of 4,180 medical, nursing, dentistry, pharmacy, and other allied health professions students. Multiple choice questions assessed knowledge before and after the educational experience. Likert scales were used for self-reporting of attitude, self-efficacy, and intended behaviors towards tobacco cessation treatments in both a pre-module and post-module survey condition. Likert scores for satisfaction were recorded in a post-module survey. Two sample paired t-tests were used to measure statistical significance. Results: The knowledge increased significantly for all modules across users. Attitude, self-efficacy, and intended behavior scores increased. The Overview course's knowledge score increased from 59to 89(t[sub](649)[/sub] = 61.9; p < 0.0001). Mean knowledge scores for all modules combined increased from 51.5to 74.0post-test. Satisfaction with the curriculum was high, with a mean score of 4.6 out of 5. Conclusions: The success of this program is evident by overall satisfaction, and increases in knowledge, self-efficacy, attitudes, and behaviors, as well as the ease with which it was deployed to thousands of students. Results of this study demonstrate that online training in tobacco cessation is an efficient and effective method of teaching students skills in tobacco cessation counseling, and can fill a vital gap in existing curricula.

Journal of Applied Sciences , 2010,
Abstract: Screening and evaluating various biomass for their potential as gasifier feedstocks can be a very complex and time consuming works. To optimize time of screening and selecting a promising fuel for gasifier, a novel method for screening of biomass using an aggregated matrix is introduced. Eleven Malaysian biomass from various resources are characterized and subsequently screened using this method based on their calorific value, O:C and H:C ratios, moisture, ash, volatiles and fixed carbon content. From the results obtained, palm kernel shell, sawdust and coconut shell are the most preferred biomass for gasification as each of these samples obtained 12 points from the aggregated matrix. The least preferred is empty fruit bunch, with only 8 points. Rubber seed kernel and coconut fiber scored 10 points while the other biomass scored 9 points. Through this novel and flexible method, users such as researchers or industrial practitioner who have limitations such as time and equipment availability are able to do an efficient screening of multiple feedstocks for their systems.

Abstract: Calcium oxide (CaO) is recognized as an efficient carbon dioxide (CO2) adsorbent and separation of CO2 from gas stream using CaO based adsorbent is widely applied in gas purification process especially at high temperature reaction. CaO is normally been produced via thermal decomposition of calcium carbonate (CaCO3) sources such as limestone which is obtained through mining and quarrying limestone hill. Yet, this study able to exploit the vast availability of waste resources in Malaysia which is cockle shell, as the potential biomass resources for CaCO3 and CaO. In addition, effect of particle size towards decomposition process is put under study using four particle sizes which are 0.125-0.25 mm, 0.25-0.5 mm, 1-2 mm, and 2-4 mm. Decomposition reactivity is conducted using Thermal Gravimetric Analyzer (TGA) at heating rate of 20°C/minutes in inert (Nitrogen) atmosphere. Chemical property analysis using x-ray fluorescence (XRF), shows cockle shell is made up of 97% Calcium (Ca) element and CaO is produced after decomposition is conducted, as been analyzed by x-ray diffusivity (XRD) analyzer. Besides, smallest particle size exhibits the highest decomposition rate and the process was observed to follow first order kinetics. Activation energy, E, of the process was found to vary from 179.38 to 232.67 kJ/mol. From Arrhenius plot, E increased when the particle size is larger. To conclude, cockle shell is a promising source for CaO and based on four different particles sizes used, sample at 0.125-0.25 mm offers the highest decomposition rate.
