Aliphatic polyesters, such as poly(lactic acid), which degrade by hydrolysis, from naturally occurring molecules form the main components of biodegradable plastics. However, these polyesters have become substitutes for only a small percentage of the currently used plastic materials because of their poor thermal and mechanical properties. Polymers that(More)
Giant soft-shelled turtle has been observed and several specimens collected in different sites on the Song Hong (Red River), Song Ma (Ma River) and Song Da (Da River) in Northern Vietnam. Morphological comparison of the specimens revealed that the skulls are different to that of Rafetus swinhoei described before by having a wide and blunt outer appearance.(More)
The aim of this thesis was to estimate the presence of Salmonella and enterotoxigenic Escherichia coli in piglets, the effect of fermented liquid feed and rice distiller’s residue as a dietary modulation of the microbial population, the presence of microflora at different sites of the digestive tract, digestibility, and to evaluate the performance of pigs(More)

A unicellular cyanobacterium that produces a large amount of exopolysaccharide (EPS) was isolated from a rice field in Phu Tho Province, Vietnam. Morphological characteristics and phylogenetic analysis using a partial sequence of the 16S rRNA gene revealed that the isolate was closely related to the genus Cyanothece. The isolate, named Cyanothece sp. Viet(More)
Genetic transformation of rice (Oryza sativa L.) mediated by Agrobacterium tumefaciens has been performed on 5 indica cultivars grown in Vietnam. Embryogenic calli derived from mature seeds were inoculated with A. tumefaciens LBA4044 in which the T-DNA contained plasmid pSBbarB-UbiCre or plasmid pSB35L-Hyg-L-Gus. Transformation efficiency recorded as the(More)
This study examines the link between Kaizen practices and different culture dimensions in Vietnamese manufacturing companies. The study follows the cultural framework suggested by House et al. (2004) and three typical Kaizen practices implemented in Vietnam such as Small Group Problem Solving, Process Control and Employee’s Suggestion. Statistical(More)
Z. Naturforsch. 2009, 64b, 323 – 327; received June 13, 2008 A new bisabolene derivative (1S∗, 2R∗, 4R∗, 7R∗, 10R∗)-1,7,10,11-tetrahydroxy-1,7,11-trimethyl-4,10(H)-2-O-cinnamoyl-bisabol-8(9)-ene (1), together with cinnamic acid (2), methyl cinnamate (3), sodium cinnamate (4) and methyl elaidate (5) have been isolated from the leaves and barks of Fissistigma(More)
Diversity methods offer the receiver with separately faded copies of the transmitted signal with the expectation that at least one of these replicas will be received properly. There are ranges of techniques available during which these faded copies can be recovered and used as part of preparations for better reception. Transmit diversity uses multiple(More)
