A case for professionalization of water management in irrigation projects in India
The heavy investment in irrigation in India has not brought the expected benefits and this article argues first that a major difficulty arises from the way irrigated water is administered. The distribution of water is controlled by irrigation engineers who lack the knowledge and information to manage water in a way that maximizes agricultural production and achieves the confidence of farmers. The staffing structure and related professional values discourage the development of a new more appropriate specialism. The article goes on to argue that a new organization of work and associated staffing structure is needed which will encourage a new professional specialization bringing together staff and expertise currently dispersed in separate specialisms in engineering, agronomy and other aspects of agriculture.
Command area development authorities for improved water management
The Command Area Development Authority (CADA) in Inaia is an 
organizational strategy for improving the performance 
of irrigation projectsthrough improved project managemenit. CADAs are the administrative mechanism where all departments of government work under a single administrative 
command. A number of strategies for improved project management and a number of improvements in project operation have resulted from using the CADA model...
Copper Phthalocyanine Improving Nonaqueous Catalysis of Pseudomonas cepacia Lipase for Ester Synthesis
The nonaqueous catalysis of lipases is significant for synthesis of high pure esters, but they usually behave low catalytic activity due to denaturation and aggregation of enzyme protein in organic phases. To improve the nonaqueous catalysis, the inexpensive copper phthalocyanine was taken as a new carrier on which Pseudomonas cepacia lipase was immobilized by physical absorption, and used for synthesis of hexyl acetate, an important flavor, via transesterification of hexanol and vinyl acetate. Results showed that the desired loading was 10 mg lipase immobilized on 10 mg copper phthalocyanine powder. When the immobilized lipase was employed in the reaction system consisted of 1.5 mL hexanol and 1.5 mL vinyl acetate at 37℃ and 160 rpm, the conversion was five fold of that catalyzed by native lipase after 1 h, and reached 99.0% after 8 h. Undergoing six times of 8-h reuses, the immobilized lipase had an activity attenuation rate 1.22% h− 1, lower than 1.77% h− 1 of native lipase, which meant that the immobilized lipase was more stable. Even at the room temperature and the static state without shaking or stirring, the immobilized lipase could bring conversion 42.8% after 10 h and the native lipase gave 20.1%. Obviously, the immobilized lipase is an available biocatalyst in organic phase and has great potential in food industry.
