Disclosed are novel synthetically-modified B. thuringiensis chimeric crystal proteins having improved insecticidal activity and broader insect host range against coleopteran, dipteran and lepidopteran insects. Also disclosed are the nucleic acid segments encoding these novel peptides. Methods of making and using these genes and proteins are disclosed as well as methods for the recombinant expression, and transformation of suitable host cells. Transformed host cells and transgenic plants expressing the modified endotoxin are also aspects of the invention.

Nanoemulsion compositions with low toxicity that demonstrate broad spectrum inactivation of microorganisms or prevention of diseases are described. The nanoemulsions contain an aqueous phase, an oil phase comprising an oil and an organic solvent, and one or more surfactants. Methods of making nanoemulsions and inactivating pathogenic microorganisms are also provided.

A device and method for emitting output light utilizes both quantum dots and non-quantum fluorescent material to convert at least some of the original light emitted from a light source of the device to longer wavelength light to change the color characteristics of the output light. The device can be used to produce broad-spectrum color light, such as white light.

A communications system consisting of a server system that stores software applications, a broadcast system that broadcasts the software applications, and a multiplicity of portable clients that each include a receiver having a tuner that is selectively tunable to receive a selected one of the software applications broadcasted by the broadcast system. The portable clients can be any type of portable data communications device, such as a hand-held, palm-top, or notebook computing device, a PDA, an intelligent cellular phone, or any other personal multimedia appliance or Network Computer (NC). The broadcast system can be any suitable satellite or terrestrial air or cable broadcast system. The software applications can consist of a broad spectrum of different software applications, such as word processing, video games, spreadsheets, address books, calendars, and the like. Each of the portable data communications devices includes a receiver that has a tuner that is selectively tunable to receive a selected one of a plurality of software applications broadcasted by a broadcast system, a user-interface that enables a user to select one of the broadcasted software applications for downloading, a processor for executing the downloaded software applications, and a modem for establishing a two-way communications link with a network control system. The two-way communications link includes a forward channel over which the portable data communication device can transmit client data to the network control system, and a return channel over which the network control system can transmit system data to the portable data communication device. The client data can include requests for unrecoverable software application data and client software download request data.

The invention comprises an apparatus for measuring the relative thickness of the lipid layer component of the precorneal tear film on the surface of an eye after distribution of the lipid layer subsequent to blinking is disclosed. An illuminator directs light to the lipid layer of a patient's eye. The illuminator is a broad spectrum light source covering the visible region and is a lambertion light emitter such that the light source is specularly reflected from the lipid layer and undergoes constructive and destructive interference in the lipid layer. A collector collects and focuses the specularly reflected light such that the interference patterns on the tear film lipid layer are observable. The collector also produces an output signal representative of the specularly reflected light which is suitable for further analysis, such as projection on to a high resolution video monitor or analysis by or storage in a computer. In order to facilitate ease of measurement, the patient's head may be positioned on an observation platform when the illuminator directs light to the lipid layer of the patient's eye.

A rare earth-activated terbium-containing garnet phosphor is capable of absorbing radiation in the range from near UV to blue and emitting a broad spectrum of visible light in the range from about 490 nm to about 770 nm. The emission of the phosphor under an excitation at 450 nm exhibits a peak in the range of maximum sensitivity of the human eye. A light source combining a UV / blue LED and this phosphor can provide a white light that is on or near the Planckian locus and may be useful for general illumination.
