Farm machinery merchandising : farmer and dealer preferences concerning used equipment guarantees, farm service centers and information services

Creator:: Singh, Ashok K.
Abstract:: Many changes have been taking place in Oregon's agriculture. Average size of farms has increased. The trend is toward fewer but larger, highly mechanized farms, leading to changed demand for farm machinery and consequently changes in farm machinery firms to meet the changing demands of farmers. In general, the research...

Frequency-domain, parameter estimation for a brushless, doubly-fed machine

Creator:: Ramchandran, Ashok
Abstract:: A Brushless, Doubly Fed Machine (BDFM) attempts to combine the advantages of conventional induction and synchronous types of electrical machines by its unique architecture. The validation of BDFM designs in an actual test environment requires the estimation of the BDFM model parameters from actual experimentation. Accurate values for the parameters...

A method for controlling and stabilizing the pitch-axis dynamics of a magnetically levitated train

Creator:: Ramchandran, Ashok
Abstract:: An electro-dynamic Magnetic Levitation vehicular system has been modelled and studied. In practice, a MagLev vehicle will consist of a number of cars which are mechanically coupled to each other. It is reasonable to assume that each of these cars will be independently controlled with the help of a supervisory...

Transmission of bovine anaplasmosis in eastern Oregon by field collections of Dermacentor andersoni Stiles=(Venustus)

Creator:: Singh, Harjinder
Abstract:: In the spring and summer of 1975 a study was conducted under natural conditions to determine whether wild adult Dermacentor andersoni Stiles would transmit Anaplasma marginale to cattle. The ticks were collected from the range pasture of Squaw Butte Experiment Station where anaplasmosis is enzootic and D. andersoni is indigenous....

Effects of intrinsic factors in the transmission of bean yellow mosaic virus by aphids

Creator:: Sohi, Sardara Singh
Abstract:: The effects of the inherent transmissibility of the virus and of the inherent transmitting ability of aphids on the transmission of bean yellow mosaic virus (BYMV) were studied along with four virus-vector relationships of BYMV and the green peach aphid, Myzus persicae (Sulz.). In addition, investigations were made on the...

Tree and crop productivity and soil organic matter changes as influenced by Leucaena hedge-row management in sub-humid India

Creator:: Singh, Rajive K.
Abstract:: The overall objective of this study was to evaluate biomass production and soil ameliorative potential of alley farming in sub-humid India. Effect of the cutting height (40, 80, 120, 160 cm) of Leucaena hedges and root barriers on biomass yield of Leucaena and maize and wheat crops were examined. Trees...

Understanding and overcoming risks to cooperation along transboundary rivers

Creator:: Subramanian, Ashok, Brown, Bridget, and Wolf, Aaron T.
Abstract:: This study reviews the experience of cooperation in five international river basins, focusing on the perceptions of risks and opportunities by country decision makers responding to a specific prospect of cooperation, and the effects of risk reduction and opportunity enhancement on the cooperation process. We explore the following five categories...

Effects of modifying the environment on flowering, fruiting, and biochemical composition of the snap bean (Phaseolus vulgaris L.)

Creator:: Singh, Jyotendra Narain
Abstract:: The effects of modifying air temperature, soil temperature, and soil moisture levels on flowering, fruiting, and chemical composition of Tendercrop snap beans were studied in experiments in the field and in the greenhouse during 1961, 1962, and 1963. High maximum temperatures of 95-105° F. during bloom reduced the percent set...

Factors affecting nitrogen nutrition of western hemlock

Creator:: Gill, Ranjit Singh
Abstract:: Preliminary fertilization trials with western hemlock have yielded responses which vary significantly from stand to stand, especially in areas near the Pacific Coast. Growth responses have varied from positive to negative in an erratic manner. Previous data did not permit validation of such hypotheses as, "the application of fertilizer to...
