Crossing behavior, RAPD analysis and chlorophyll flourescence in relationship to the geographic adaption of birdsfoot trefoil (Lotus corniculatus L.)

Creator:: García de los Santos, Gabino
Abstract:: Birdsfoot trefoil (Lotus corniculatus L.) is a popular perennial, non-bloating forage legume used for pasture, hay and silage throughout the temperate regions of Europe, Asia Minor, North Africa and North and South America. It is regarded as the most morphologically and biochemically variable species in the genus. Research investigating the...

Selenium measurement in ground water and biological material by instrumental neutron activation analysis

Creator:: Yousef, Samir
Abstract:: The utilization of ⁷⁷ [superscript m] Se, half life 17.5 s, and ⁷⁵ Se, half life 119.8 d, for quantification of trace amounts of Se in well water and biological materials by means of instrumental neutron activation analysis (INAA) is described. A Se detection limit of 0.03 ppm was achieved...

Nature of the inheritance of gluten strength and carotenoid pigment content in winter by spring and durum wheat crosses (Triticum turgidum L. Var. durum)

Creator:: Ammar, Karim
Abstract:: Durum wheat cultivars for North-Eastern Oregon have to be competitive in terms of their yield potential with soft white winter wheat cultivars and meet strict quality requirements of the milling industry. Combining the high yield potential of fall planted durum wheat cultivars which have an acceptable level of winter hardiness...

The effect of levels of cooperation within physical science laboratory groups on physical science achievement

Creator:: Chang, Huey-por
Abstract:: The purpose of this study was to investigate the effect of the levels of group cooperation on students' achievement during a series of physical science laboratory activities. Six intact seventh grade physical science classes taught by two teachers, with each teacher instructing three classes, were selected from two middle schools....

Sliding-mode control of the super maneuverable aircraft

Creator:: Koo, Chang Sul
Abstract:: In this thesis, A nonlinear methodology for the control of the highly maneuverable, high performance aircraft HARV (F-18) is studied by using sliding-mode control (SMC). This control law, which takes a continuous function when the input constraints are not considered, satisfies the reachability condition by which concerned states are driven...

Root decomposition in three coniferous forests : effects of substrate quality, temperature, and moisture

Creator:: Chen, Hua
Abstract:: Controls of substrate quality, temperature, and moisture on woody root decomposition in the Pacific Northwest were explored using chronosequences, time series, laboratory incubations, and simulation modeling approaches at three sites: Cascade Head (CAH), H. J. Andrews (HJA), and Pringle Falls Experimental Forests (PRF). In the chronosequence study, a structural component-oriented...

High accuracy CMOS switched-current ladder filters

Creator:: Hoei, Jung-sheng
Abstract:: Clock-feedthrough effects, channel-length modulation and device mismatch are the main causes of the inaccuracy of Switched-Current (SI) circuits. In this paper, these non-ideal effects are analyzed. A high-performance current mirror, namely regulated cascode current mirror, which eliminates drain voltage variation problem is introduced. By using this current mirror as a...

Current mode analog and digital circuit design

Creator:: Liang, Guojin
Abstract:: In this dissertation, two important current mode circuit design subjects have been explored. In the first part, the switched-current circuit technique has been investigated. The fundamental performance and limitations of this technique are explored. One of the major limitations, the signal distortion caused by clock feedthrough has been substantially reduced...
