Production of Recombinant Baculoviruses
Published Sunday, November 26, 2000This invention pertains to methods that facilitate production of recombinant baculoviruses that have been engineered for use as biological control agents. Specifically the invention concerns the construction of a system for regulating gene expression employing the tetracycline gene (tet) operator-repressor system. The tetracycline repressor is...

A Process for Coating Biological Pesticides and Compositions Therefrom
Published Tuesday, October 31, 2000Baculoviruses are known biological materials having insecticidal activity. The commercial utility of these materials has been limited though because, without special formulation, like most biological materials are readily deactivated by the UV radiation in sunlight.The incorporation of UV protectants in a variety of ways is known and...

Recombinant Baculovirus Insecticides
Published Tuesday, October 31, 2000This invention relates to modifying nuclear polyhedrosis virus (NPVs), a type of Baculovirus distinguished from non-occluded Baculovirus (NOVs) and granulosis viruses (Gvs). These viruses are in general slow to kill insects but have been engineered to kill a host in 20-30% less time than wild type NPVs by engineering them to express neurotoxins...

Smart Gun Barrels With Embedded Fiber Optic Sensors
Published Tuesday, October 17, 2000It is a huge tactical advantage in warfare to have weapons systems with an effective firing range longer than the firing range of an enemy. However, improving firing accuracy at a longer range is a constant challenge in modern weapon development. For battle tanks, warships and artillery, the gun barrel is a crucial part of the weapons system that...

Living Cyclopolymerization of Nonconjugated Dienes
Published Wednesday, October 11, 2000Researchers at the University of Maryland, College Park, have invented methods and a catalyst for the cyclopolymerization of non-conjugated dienes. The catalyst is an amindinate-based zirconium precatalyst. Upon activation with a borate co-catalyst, it not only allows for the stereospecific living polymerization of alpha-olefins, but can...

Fiber Optic Breadboard
Published Wednesday, October 11, 2000Laboratory space utilized in optics research is often an expensive commodity. Unfortunately, the majority of platform equipment used in laboratories is planar in nature and not modular. This planar arrangement tends to consume a lot of valuable lab space and often results in confusing layouts that make troubleshooting during experiments very...

Wet Gas Temperature Measurement Probe
Published Wednesday, October 11, 2000Current technology makes it difficult to accurately detect hot gas temperature when the hot gas is laden with water droplets. The droplets tend to deposit on detecting surfaces resulting in evaporative cooling that causes inaccurate measurement of the gas temperature. For example, this problem is particularly evident in fire sprinkler arrays...

A Method for Eliminating the Requirement for Synchronized Clocks in Distributed Routing Approaches that are Dependent on the Temporal Ordering of Events
Published Wednesday, October 11, 2000A new approach to routing in highly dynamic networks has been recently introduced. The Temporally Ordered Routing Algorithm (TORA) is a significant departure from traditional datagram routing approaches used in static or quasi-static hardwired networks. A unique aspect of TORA is the use of time information to establish the temporal-order of...

IMPACT Agent Development System
Published Wednesday, October 11, 2000An intelligent agent is a program that gathers information or performs other services without a user's immediate presence and on a regular schedule. Typically, an agent program, using pre-set parameters, searches and gathers information of interest on a network, and presents it to the user on a periodic basis. For example, agents have been...

Polarization and Wavelength Diversity for Fade Resistance in Optical Wireless Communication Systems
Published Wednesday, October 11, 2000Optical wireless communication systems are line-of-sight optical links using lasers or light-emitting diodes (LED). Data is transmitted on a laser or LED beam using some form of amplitude, frequency, phase, or polarization modulation, or a combination of these. In these systems an optical beam passes from transmitter to receiver along a path...
