Input-output modeling and multiplier analysis are used to assess Taiwan's five petrochemical industries, based upon their economic contribution and potential impacts on energy consumption and CO2 emission. In addition, a consolidated index system was developed for evaluating energy and economic efficiencies as well as targets for CO2 reduction. Results indicate that petrochemical materials (PM)...

This study evaluates granular liquefaction triggering case-history data using a nonparametric approach. This approach assumes no functional form in the relationship between liquefied and nonliquefied cases as measured using cone penetration test (CPT) data. From a statistical perspective, this allows for an estimate of the threshold of liquefaction triggering unbiased by prior functional forms,...

The selection of proper refrigerants for natural gas liquefaction processes play a key role in cycle?s efficiency. Mixed have been proven to improve exergy efficiency over single pure refrigerant. However, the future some these with higher global warming potential index are unknown due continuous restriction being enforced by energy and environmental agencies past few decades. This study examin...

propranolol (pl), a non-selective beta-blocker, is a cardiovascular drug widely used to treat hypertension. the present study was concerned with assessing the cytogenetic effects of this drug on chinese hamster ovary (cho) cell line. mtt assay was then carried out to determine the cytotoxicity index (ic50) of the drug. the ic50 value of pl was 0.43±0.02 mm. to investigate the clastogenic effect...

Wood liquefaction was conducted using phenol as a reagent solvent with a weak acid catalyst in two different reactors: (Alma et al., 1995a.) an atmospheric glass reactor and (Alma et al., 1995b.) a sealed Parr reactor. Residues were characterized by wet chemical analyses, Fourier transform infrared (FT-IR) spectroscopy, and X-ray diffraction (XRD). The FT-IR spectra of the liquefied wood residu...

a self-regulated high-copy number plasmid containing chloramphenicol resistant gene, for the production of recombinant proteins under the regulation of bacteriophage ?pl promoter, was constructed. the designed 5024 base pair expression plasmid contained a heat sensitive repressor ci857 coding gene to regulate the function of ?pl promoter under heat shock induction. using the constructed vector,...

In this work, poloxamer (PL)-based binary hydrogels, composed of PL 407 and PL 188, were studied with regard to the physicochemical aspects of sol-gel transition and pharmaceutical formulation issues such as dissolution-release profiles. In particular, we evaluated the cytotoxicity, genotoxicity, and in vivo pharmacological performance of PL 407 and PL 407-PL 188 hydrogels containing tramadol (...

Liquefaction of soil is one of the major causes for the significant damages to the buildings, lifeline systems and harbor facilities caused by the earthquakes. At present artificial intelligence techniques such as artificial neural network (ANN) and support vector machine (SVM) based models are found to be more efficient compared to statistical methods. The present study discusses about the eva...

This paper presents a hybrid genetic algorithm (GA) and support vector machine (SVM) techniques to predict the potential of soil liquefaction. GA is employed in selecting the optimal values of the kernel function and the penalty parameter in SVM model to improve the forecasting accuracy. The database used in this study includes 109 CPT-based field observations from five major earthquakes betwee...
