New pesticide metal complexes for controlled release     

B. Prabhu Prasad  M. Lakshmi Kantam  B. M. Choudary  K. Sukumar  K. Satyanarayana 《Pest management science》1990,28(2):157-165

Six new pesticide metal complexes were synthesised, characterised and evaluated for controlled release by chemical and bioassay methods. Chemical assay and bioassay data demonstrate the increased persistence and increased shelf life of the pesticides upon complexation.  相似文献   

Effect of protein level and vegetable matter on growth and food conversion efficiency of brown shrimp     

A. Venkataramiah  G.J. Lakshmi  Gordon Gunter 《Aquaculture (Amsterdam, Netherlands)》1975,6(2):115-125

Growth increment, food conversion efficiency and survival rates of postlarval shrimp Penaeus aztecus of two size groups (9.5 mm and 20.5 mm mean length) were compared, using foods of different protein level and vegetable content. Animals were provided with two sets of food pellets containing 40 (control), 50, 60, 70 and 80% protein. In one of the sets, the vegetable matter was adjusted to that of the control level (5.5%); in the second set no such adjustment was made. Growth rates of both size groups decreased with increased protein level and with decreased vegetable matter in their food. Addition of vegetable matter to the diet improved the relative protein conversion efficiency and survival rates but did not alter the growth trend with respect to the different high protein levels present in the food. Based on laboratory experimental evidence that the shrimp certainly eat some kinds of plant material, the significance of their association with grass beds and marshes of the estuaries is discussed.  相似文献   

Tissue expression and developmental regulation of chicken cathelicidin antimicrobial peptides

ABSTRACT: Cathelicidins are a major family of antimicrobial peptides present in vertebrate animals with potent microbicidal and immunomodulatory activities. Four cathelicidins, namely fowlicidins 1 to 3 and cathelicidin B1, have been identified in chickens. As a first step to understand their role in early innate host defense of chickens, we examined the tissue and developmental expression patterns of all four cathelicidins. Real-time PCR revealed an abundant expression of four cathelicidins throughout the gastrointestinal, respiratory, and urogenital tracts as well as in all primary and secondary immune organs of chickens. Fowlicidins 1 to 3 exhibited a similar tissue expression pattern with the highest expression in the bone marrow and lung, while cathelicidin B1 was synthesized most abundantly in the bursa of Fabricius. Additionally, a tissue-specific regulatory pattern was evident for all four cathelicidins during the first 28 days after hatching. The expression of fowlicidins 1 to 3 showed an age-dependent increase both in the cecal tonsil and lung, whereas all four cathelicidins were peaked in the bursa on day 4 after hatching, with a gradual decline by day 28. An abrupt augmentation in the expression of fowlicidins 1 to 3 was also observed in the cecum on day 28, while the highest expression of cathelicidin B1 was seen in both the lung and cecal tonsil on day 14. Collectively, the presence of cathelicidins in a broad range of tissues and their largely enhanced expression during development are suggestive of their potential important role in early host defense and disease resistance of chickens.  相似文献

Model Studies on Salt and Water Balances at Konanki Pilot Area, Andhra Pradesh, India     

A. Srinivasulu  Ch. Sujani Rao  G.V. Lakshmi  T.V. Satyanarayana  J. Boonstra 《Irrigation and Drainage Systems》2004,18(1):1-17

The salt and water balances at Konanki pilot area in Nagarjunasagar project right canal command in Andhra Pradesh State of India were analysed using SALTMOD. The model was calibrated by using two-year data collected in the pilot area. From the calibration, the leaching efficiencies of the root and transition zone were estimated as 65% and the out going natural sub-surface drainage was determined as 50 mm per year. The model predicts that the root zone soil water salinity will be reduced to 4, 3 and 2.5 dS/m (from an initial value of 11.5 dS/m) during the first, second and third seasons within six years after installation of the drainage system. Next, the situation prior to the installation of the drainage system was reconstructed using the model. Finally, sensitivity analyses were made to study the effects of varying drain depth, spacing and amount of irrigation water applied on root zone salinity and depth to water table. Here, the model predicted that closer than the present spacing or further deepening of the drains from the present depth of 1 m to 1.4 m will not have any better influence on the reduction of the root zone salinity than in the present situation. These simulations also suggested that by applying 80% of the present amount of irrigation water, the root zone salinity can be brought down to 5 and 4 dS/m by second and fourth years, respectively and this will in turn reduce the problem of water logging and salinity to some extent.  相似文献
