Summary
Spirulina platensis has been grown in an outdoor pilot production unit, with an exposed surface area of 450 m2, on a medium consisting of raw domestic sewage supplemented with sodium bicarbonate and nitrate or urea fertilizer. The chemical composition and yield of the biomass grown on sewage-nitrate was comparable to that grown on synthetic medium. The protein content was much lower in the alga cultivated in sewage-urea medium.NBRI Research Publication No. 143 (NS). 相似文献

Interruption of acoustic communication and mating in a leafhopper and a planthopper by aerial sound vibrations picked up by plants 总被引:2,自引:0,他引:2
Summary Each sex of the cotton leafhopper and the rice brown planthopper communicates with the opposite sex by certain specific sound vibrations which travel through the plant surface and lead to mating. External sounds of certain frequencies, viz., 200 c/sec, generated by a harmonium or an audio-oscillator are picked up from the air by the plants and interrupt the acoustic communication as well as mating of the insects. Notes with harmonics are effective whereas pure notes are ineffective.The authors gratefully acknowledge P.L. 480 grant No. FG-IN-551 from the US Department of Agriculture for project No. IN-ARS-90, under which this work was carried out. 相似文献

A program can be analyzed and studied by dividing it into elements and subelements. Graphical presentation of the driver power and dependence of the subelements of the identified elements assists in their classification in categories representing the nature of the role each subelement plays as a variable in the program. This paper presents methodology for the hierarchy building of subelements, graphical presentation of their driver power and dependence, and classification in categories such as autonomous, dependent, linkages, and independent variables. The paper further presents a case study of energy conservation in the Indian cement industry to determine the hierarchy of program plan elements and to classify them in categories. Key variables of the program are also highlighted. 相似文献

Zusammenfassung Die Fütterungsreaktionen beim erwachsenenTribolium castaneum (Herbst.) zeigen, dass keine der verschiedenen Kohlenhydrate das Fressen besonders anregt. Der Nährwert dieser Kohlenhydrate nimmt in folgender Reihenfolge ab: Stärke und Maltose; Glukose, Melibiose und Milchzucker; Rohrzucker, Fruchtzucker, Melezitose, Raffinose und Cellobiose. 相似文献

Summary Out of the 9 new non-alkylating compounds screened againstC. trachypterus, the compounds 62206, 24220 and 51160 have been found most effective, 51007 and 50882 exhibit intermediate effectiveness, 61914 only slightly effective and 50994, 2406 and 51240 almost non-effective.This work was financed out of PL 480 USA funds. 相似文献
