DL-alpha-Difluoromethylornithine (DFMO), an inhibitor of the polyamine biosynthetic enzyme ornithine decarboxylase (ODCase; EC 4.1.1.17), strongly retards the growth of several species of phytopathogenic fungi in vitro. Such inhibition can be completely reversed by putrescine or spermidine, confirming the essentiality of polyamines for growth of fungal hyphae. We now have discovered that DFMO can protect a range of plants against a wide range of fungi. For example, DFMO can protect bean plants (Phaseolus vulgaris Linnaeus cv. Pinto) against infection by uredospores of the bean rust fungus, Uromyces phaseoli Linnaeus, race O. Unifoliolate leaves of 10-day-old greenhouse-grown seedlings were sprayed with 400 ul per leaf of DFMO at various concentrations in 0.01% Tween 20 at pH 7.0 before or after inoculation with uredospores of Uromyces. After 16 hr in darkness in dew chambers to facilitate spore germination, plants were transferred to the greenhouse, arranged randomly, and examined for local lesions 7 days later. All concentrations of DFMO 0.50 mM or higher gave complete protection against the pathogen; at lower concentrations, postinoculation treatments with DFMO were generally more effective than preinoculation. The appearance of lesions on plants treated with lower concentration of DFMO was retarded 2-6 days. DFMO also confered protection on unsprayed parts of treated plants, indicating the translocation of some protective effect from sprayed areas. DL-alpha-Difluoromethylarginine, an analogous inhibitor of arginine decarboxylase (ADCase; EC 4.1.1.19), which is the rate-limiting enzyme in an alternative pathway for polyamine biosynthesis in higher plants, confers little protection even at 5mM. This emphasizes ornithine decarboxylase as the biochemical locus of choice for the prevention of plant diseases by inhibiting polyamine metabolism. DFMO has also been shown to be an effective synthetic fungicide for the following: protects tomato plants against Verticillium wilt fungus; protects wheat against stem rust fungus; protects wheat against powdery mildew fungus; protects Tendergreen bean plants against powdery mildew fungus; protects the MacIntosh apple leaf against the powdery mildew fungus; protects Ogle oats against leaf rust fungus; and protects corn against the corn rust fungus.

A method of high-speed magnetic resonance imaging in which the object to be imaged is placed in a high static magnetic field. Nuclear spins are excited in an image area in a selected plane of the object by superimposing a slice-selection gradient along an axis and applying a pulse of radio frequency magnetic field. Following an encoding pulse sequence and rephasing of the nuclear spins by the application of a 180.degree. radio frequency pulse, mutually orthogonal phase-encoding and readout gradients are alternately applied in the image plane to effect a traversal through spatial frequency domain (k-space). In a preferred embodiment of the invention, the readout gradient is applied as a continuous sinusoidal wave, resulting in a slight overlap between the phase-encoding and readout gradients. If phase errors vary slowly in time, only a partial k-space trajectory is required. Chemical shift is eliminated either by the application of a suppression pulse of RF field or by tailoring the frequency spectrum of the rephasing pulse so as to preclude rephasing of one or other of the chemical moieties.

A level indicator control system including a microprocessor that controls the height and, therefore, the amount of the substance, such as fluid or granular solid, to be contained in a closed or open tank or vessel. The system provides calibrated digital or analog output that shows the extent to which the tank is filled with substance at substantially any level. A scale, in percent, each value representing the percentage of fullness of the tank, is produced after low and high limits, representing any low and high substance levels respectively, are provided to the microprocessor. The scale values are a function of the changes in capacitance between the stationary probe and the tank wall as the level of substance approaches or submerges the probe. The system finds its probe capacitance and sets its own high and low control set point limits automatically. Thereafter, the system uses the instantaneous probe capacitance and the capacitance values representing the high and low substance levels to provide the calibrated digital or analog output. For example, when the substance in the tank exceeds the high limit set point value, the control system prevents more fluid or granula solid from entering the tank.

The apparatus can compute the oxygen content of patients with weak pulses, or unstable physiological states, or both, by using, preferably, a plurality of independently settable gains, to maintain the signal level within a range suitable for accurate measurement. In addition, the apparatus preferably compensates for drift in the non-pulsatile component which can be caused when the patient's blood pressure, for example, becomes erratic, thereby increasing the accuracy of its computation of the oxygen content of the blood. To the extent possible, the signals produced for the different wavelengths are time-multiplexed onto a single channel. A test mode is preferably provided, in which only one wavelength of radiation is produced, resulting in a computation equal to what would be obtained in normal operation if the amounts of sensed radiation were the same for all wavelengths.

Speech processing apparatus and methods utilizing a circuit for electronically deriving from speech over time a series of coordinate values representing positions of points on a path in a mathematical space which path positions represent the speech. An electronic memory prestores phonetic representations in correspondence with indicia of a glide in the path which indicia represent a nucleus in the space at which the glide begins and a range of directions of offglide on the path from the nucleus. A trajectory parameter is electronically computed from the series of coordinate values. When both the trajectory parameter satisfies a predetermined condition for significance and a coordinate value currently reached by the speech is within a predetermined region of such values, a signal is produced. The speech on the path is electronically analyzed in response to the signal for occurrence of a position in the nucleus and an offglide in said range of directions which offglide happens before another significant trajectory parameter occurs. Upon occurrence of such indicia of a glide, the phonetic representation corresponding to the glide indicia is obtained from the electronic memory. Other apparatus and methods for producing a segmentation index signal representing the trajectory parameter are disclosed.

The value of a time variable representing time is progressively incremented and the message indicated by each enqueued representation is sent to the model as the value of the time variable surpasses the value of the time stamp of the representation. The message representations and the value of their time stamps are created according to the requirements of the constraint network such that the messages cause the model to perform the appropriate actions at the appropriate times in order to satisfy the temporal constraints defined by the constraint network.

The present invention provides an interface for exchanging clocking signals and other information between a computer subsystem based on a first clocking scheme of a first processor and a second processor. The second processor and computer subsystem are coupled to the interface. The interface may be included on a circuit card that is removably coupled to the computer subsystem. The interface includes an emulator for emulating the first clocking scheme thereby enabling the second processor to function with the computer subsystem.

A system for interfacing a Processor to a Coprocessor using standard bus cycles. The Processor, upon encountering in its instruction stream an instruction having a particular Operation word format, will transfer a Command word following the Operation word to a particular Coprocessor designated by a Coprocessor Identity field in the Operation word, Upon decoding the Command word, the Coprocessor will respond with any of a set of response primitives whcih define functions which the Coprocessor requires to Processor to perform in support of the Command by the Coprocessor. The interface provides for all functions which the Coprocessor may require, including selective vectoring to appropriate exception handlers.

A telephone answering system with paging function is adapted to transmit a prerecorded outgoing message to a calling party through a closed loop of telephone lines established upon reception or a telephone calling signal, and record an incoming message from the calling party after the outgoing message is transmitted. The system operates to receive a signal representative of the caller's telephone number sent from the calling party through the telephone lines to store the same signal in a memory, and then automatically and temporarily release the closed loop, and thereafter reestablish the closed loop for calling a preset telephone number of a paging center. Further, the system transmits the stored signal representing the caller's telephone number to the paging center through the telephone lines upon reception of an answer from the center.

A key telephone system includes a temporary registration memory for temporarily storing operating data and a final registration timing data memory for storing final registration timing data, including a timing condition for transferring contents of the temporary registration memory to the operating data memory. Operating data input by a user and the final registration timing data are written into the temporary registration memory and the final registration timing data memory, respectively, from a data input unit connected to the main unit during a data setting mode. The system discriminates establishment of the timing condition designated in accordance with the final registration timing data stored in the final registration timing data memory, whereupon the operating data stored in the temporary registration memory is transferred to the operating data memory.

A novel initiator (blasting cap) for explosives is provided. The initiator, which may be electric or non-electric, comprises a tubular metal shell having within a base charge, a delay train, a priming charge and an ignition means. Interposed between the delay train and the priming charge is an annular collar or ring of resilient material in contact with the inner wall of the metal shell. The construction results in a markedly improved resistance against shock initiation.

A barrier type contraceptive is an umbrella-like device including a flexible, barrier member with a plurality of radially disposed resilient stiffening members associated therewith. The stiffening members bias the barrier member into a generally planar configuration while allowing for the device to be folded into a generally fusiform shape for insertion.
