Spectrometer

Ultraviolet spectrometer measures pure monochromatic wavelengths in predetermined narrow wave bands. Two stages are incorporated: stationary dispersed beam is intercepted by array of slits cut into plate at discrete wavelength locations; second stage is inverted spectrometer which recombines dispersed spectrum at single exit slit

Research accomplished at the Knowledge Based Systems Lab: IDEF3, version 1.0

An overview is presented of the foundations and content of the evolving IDEF3 process flow and object state description capture method. This method is currently in beta test. Ongoing efforts in the formulation of formal semantics models for descriptions captured in the outlined form and in the actual application of this method can be expected to cause an evolution in the method language. A language is described for the representation of process and object state centered system description. IDEF3 is a scenario driven process flow modeling methodology created specifically for these types of descriptive activities

Study of environmental effects on cellular autoxidation Final report, Mar. 1, 1965 - Feb. 29, 1966

Oxygen toxicity as result of increased lipid peroxidation - lysosomal enzymes in rats exposed to 100 percent oxygen, and stability of rat liver and brain lysosome

Development of lunar nomenclature

A system of unification and standardization for lunar nomenclature was developed. The following recommendations were made for use in future lunar cartography: (1) satellite craters, previously designated by letters will be named; (2) names will no longer be restricted to scientists, but will also include great contributors to human knowledge and human culture; and (3) a system of grids for dividing the moon into 144 regions and subdividing these regions into 2304 provinces will be used

Report no. 1 : Anton Bruun cruise A : Aden-Bombay, February-March, 1963

En route from the U. S. to Bombay, India during February - March, 1963 an unscheduled oceanographic section of 13 stations was made in the Arabian Sea between Aden and Bombay. Standard hydrographic casts were made to 1400 meters indicated depth (1000 meters at Stations 1-3) for meas9rement of temperature, salinity, dissolved oxygen, phosphate, nitrite, nitrate and silicate. A large, plastic sampler was used to obtain water samples from depths corresponding to 100, 50, 25, 10 and 1% of the sunlight incident to the surface. These samples were used for measurement of primary productivity (C-14 method), phytoplankton pigments, particulate carbon, nitrogen and phosphorus

Can the productivity of mango orchards be increased by using high-density plantings?

Mango (Mangifera indica) trees are traditionally established at about 100–200 trees per ha and eventually grow into large specimens 10 m tall or more, making spraying and harvesting difficult. It also takes a long time to recover the initial costs of establishing and maintaining the orchard. There has been considerable interest in planting orchards up to 4000 trees per ha to take advantage of early production and to increase economic returns. However, trees planted at high density soon begin to crowd and shade each other and production falls. We reviewed the performance of high-density orchards in different growing areas, and the role of dwarfing cultivars and rootstocks, tree canopy management and the growth regulator, paclobutrazol to control tree growth. There has been no general agreement on the optimum planting density for commercial orchards which vary from 200–4000 trees per ha in different experiments. Some potential dwarfing material has been developed in India and elsewhere, but these cultivars and rootstocks have not been widely integrated into high-density orchards. Canopy management needs to take into account the effect of pruning on the regrowth of the shoots and branches, light distribution through the canopy and the loss of the leaves that support the developing crop. Pruning must also take into account the effect of vegetative growth on flower initiation. Annual light pruning usually provides better fruit production than more severe pruning conducted less regularly. There have only been a few cases where it has been demonstrated that paclobutrazol can counteract the negative effect of pruning on flowering and fruit production. There are also concerns with residues of this chemical in export markets and contamination of ground waters. The future development of high-density plantings in this crop is dependent on the use of dwarfing cultivars and/or rootstocks and better canopy management strategies. Dwarfing cultivars and rootstocks should provide small- to medium-sized trees with medium to large yields. This can readily be identified in experiments by examining the relationship between yield and tree growth. Research on canopy management should assess the impact of pruning on flowering, light distribution within the canopy and the leaf area supporting the developing crop. The productivity of mango is not likely to be increased by the use of high-density plantings without extensive efforts in plant breeding and canopy management
