Full textThe P-3 Orion maritime aircraft has been the U.S. Navy's primary maritime patrol aircraft since its fleet introduction in 1962. Naval Aviation Systems Command (NAVAIR) has determined that the P-3 fleet has sufficiently aged to warrant a replacement. The replacement aircraft is currently undergoing the conceptual phase of development and it is during this period that NAVAIR is interested in evaluating the trade-off between operational availability and the associated cost to achieve this operational availability. This thesis developed a simulation tool that was used to investigate relationships that affect cost and operational availability of the new (notional) aircraft on a deployment. The simulation tool was exercised for select scenarios in order to gain insights into the value of investing funds in additional aircraft versus the value of investing funds in increased component reliability. The simulation was developed to be very flexible and extensible, enhancing its value for future analyses. Required data inputs into the simulation tool are formatted utilizing a new technology called Extensible Markup Language (XML) which facilitates use of the data in nearly all computer software packages. The model is robust in nature and can be applied to a wide variety of aircraft.

Full textEDTA and HEEDTA were also tested in a 4-week greenhouse study for efficiency at increasing plant available P to corn (Zea mays L.) in two soils. Phosphorus was added with and without the addition of chelating agents to the center of the pot, simulating a starter band of P. After 4weeks, soils were analyzed for WSP, Mehlich-1, and Mehlich-3 P and corn above- and below-ground biomass was quantified and analyzed for total P concentration. Without the presence of chelating agents, concentrations of WSP, Mehlich-1 P, Mehlich-3 P, above- and below-ground biomass, and TKP increased linearly as P fertilizer rates increased at 0, 9.6, 19.3, 28.9, and 38.5 kg P ha-1. Decreased P sorption using chelating agents was not observed in this experiment. However, with the results from the soil incubation, chelating agents do show potential for increasing plant available P, but the application and incorporation method needs to be further studied.

Full textIncludes bibliographical references (leaves 64-83).
Legumes are unable to persist through post-fire succession in fynbos vegetation of the CFR unlike species in families such as Proteaceae and Restionaceae. The majority of fynbos legumes are seeders which tend to be shorter-lived than co-occurring resprouters. Seeders are likely to have a higher nutrient requirement than resprouters as they tend to invest more biomass- above ground, grow faster and produce more seed. In the oligo-trophic soils occupied by fynbos, symbiotic N2-fixation enables legumes to overcome low N availability but not low P availability. I hypothesized that: legumes are less effective at acquiring P from sparingly soluble sources compared with members of Proteaceae and Restionaceae ; legume seeders occupy soils with a higher nutrient status than resprouters. P-acquisition strategies of legumes and non-legumes were assessed.

Full textThe deficiency of soil minerals, particularly phosphorus (P) is a major limitation for growth and development of nitrogen-fixing by legumes. The application of phosphate fertilizers is a traditional practice to meet the needs of plant P. Thus, to test the effectiveness of use of P for symbiotic nitrogen fixation (NSF) under P deficiency, several recombinant inbred lines (RILs) of beans in their contrasting tolerance to P deficiency have been used. The main objective of this study is to assess the ability of these RILs to improve the fertility of soils deficient in phosphorus (P) and its relationship with growth and nodulation of the legume. To achieve these objectives, some experiments were conducted in greenhouses and fields. Under controlled conditions (greenhouse) and uncontrolled conditions (field), the results showed decreasing in soil pH associated with Proton release H+ and P acquisition. The increasing in available P had a positive effect on nodulation and growth of some RILs tested. Also, improving the ability of these RILs to fix atmospheric nitrogen and release H+ by nodulated roots were quantified in a controlled environment. Thus the decreasing in soil pH has reduced the un-availability of P in soil solution by transforming it into a bio-available form to the plants. In addition, the results showed significant differences between RILs in biomass and nodulation as observation in sites. We conclude that, in addition to their ability to fix nitrogen, effective use of phosphorus to save mineral fertilizer and reduce the pollution risks and could improve the availability of soil P

Full textConsidering that there is controversial information about the effects of P (phosphorus) Zn (zinc) interaction, it is hypothesized that the interaction P-Zn is a response to the sum of nutritional relations that occur in the level of plant and in the soil together, as a consequence of plant development and adaptive responses of cotton. The aim of the present study was to evaluate the mechanisms of P-Zn interaction in the soil-plant system for the cotton plant (Gossypium hirsutum L.), using a soil chemistry approach (P fractionation and sequential extraction of Zn in the soil), absorption dynamics of these elements (genomics - regarding the expression of genes related to P uptake) and plant physiology and nutrition (as regards the determination of acid phosphatase activities, oxidative stress, as well as gas exange and photochemical changes). To achieve the objectives of this proposal, four experiments were carried out, three in nutrient solution and one in soil. In the experiment I, we aimed to describe the availability of P and Zn in rhizosphere soil in response to P and Zn doses in two classes of soil cultivated with cotton (Gossypium hirsutum L.). In the experiment II, the objective was to investigate the effect of the interaction P-Zn on the accumulation of nutrients in the plant tissue; on changes in the photosynthetic process - determined by gas exchange; and consequent changes in cotton growth in response to P and Zn nutrition. In the experiment III, the objective was to verify the physiological availability of P and Zn by the enzymatic activity of acid phosphatase and carbonic anhydrase, as well as to describe the effect of the interaction in the gas exchanges, photochemical and antioxidant system responses of cotton plant. Finally, in the experiment IV it was characterized the PHO1 gene (phosphate transporters in roots to xylem) in cotton and evaluated the effect of the P-Zn interaction on PHO1 expression in Gossypium hirsutum
