摘要:
The molten exterior surface portion of a hot dip galvanized steel strip is solidified after the strip is withdrawn from a bath of molten zinc by spraying finely divided particles of a liquid nucleating agent for initiating solidification. The particles are sprayed into an electrostatic field alongside the strip. The particles are initially directed along a path which avoids impingement against the strip. However, the smaller particles are attracted to the strip under the influence of the electrostatic field, to initiate solidification. The larger particles have a momentum along their path large enough to resist the influence of the electrostatic field, thereby permitting the larger particles to continue along a path which avoids impingement. This minimizes the formation of undesirably large spangles and an undesirable surface appearance on the strip.

A DC superconducting coaxial transmission system provides electrical transmission of 5,000 megawatts of energy while simultaneously delivering liquid hydrogen. The transmission system includes a coaxial transmission segment including an inner superconductor, an outer superconductor disposed in surrounding relation to the inner conductor, and a dielectric insulator disposed between the inner superconductor and the outer superconductor. Liquid hydrogen surrounds the superconductors. Three phase transformers and poly phase rectifier/inverters provide a DC voltage source to the superconductors from the electrical grid. In one embodiment, a switching circuit connected between the voltage source and the superconductor injects a cancellation current component into the direct current flow. The cancellation current component is polarized to flow in a direction opposite to the direct current flow to produce a current zero, thus enabling safe interruption of the high DC current while minimizing the magnitude of transient voltages during switching.

An antiviral/immunomodulatory response in an animal is induced by oral administration to an infected animal, including humans, of a human α-interferon. Methods of conferring resistance or mitigating the effects of exposure to a virus including avian influenza are described.
摘要:
A mixture of α-interferons (IFN-α) is used in vitro or in vivo as an antimicrobial agent or anticancer agent. It may be administered by topical application to oral or nasal, and/or buccal mucosa to combat the effects of infection by bacteria or protozoa, cancer, or other pathogenic disease process (e.g., autoimmune or neurodegenerative disease).
摘要:
Severe acute respiratory syndrome is treated with a natural human alpha interferon, a dsRNA or both natural human alpha interferon and a dsRNA. Avian influenza is treated with natural human alpha interferon, neuraminidase inhibitor(s) and ribavirin. Effects of influenza virus are mitigated with a dsRNA in combination with a neuraminidase influenza virus inhibitor. These two products, dsRNA, and alpha interferon, have therapeutic utility either given preventively (prophylactically) or in treatment of active disease. These unique immunological/antiviral actions, operating through immunological “cascades” ameliorates the lethal effects of viral mutation which, by causing resistance to commonly available drugs, greatly accelerates the death rate. For example, in 1918-1920, Avian Influenza caused the death of approximately 40 million people worldwide (ref. National Geographic, September, 2005).
摘要:
A hot dip coating system comprises a bath of molten coating metal contained in a vessel having a strip passage opening located below the top surface of the bath. A metal strip is directed along a path extending through the strip passage opening and through the bath of molten coating metal, to coat the strip. An electromagnet is employed to prevent the escape of the bulk of the molten coating metal from the bath through the strip passage opening while permitting the strip to move along its path. Expedients are provided to reduce leakage of molten coating metal through the strip passage opening.
摘要:
Virus infections promoting Chronic Fatigue can be diagnosed by assessing the 2'-5'A/RNase L pathway, including measurement of 2'-5'A oligonucleotide levels in the patient's circulating peripheral leucocytes, and comparing these resuls with those of healthy individuals. Double-stranded RNAs, notably mismatched dsRNAs, when administered in appropriate amounts, increase the 2'-5'A and normalize the antiviral pathway in patients with Chronic Fatigue Syndrome and improve the clinical symptoms.
摘要:
A hot dip coating apparatus and method for coating a continuous steel strip, wire, or like continuous member with zinc, aluminum, tin, lead, or alloys of each. A molten coating bath is contained in a vessel having a bottom opening upwardly through which the steel member is directed. Magnetic containment devices located below the vessel's bottom opening prevent the escape of molten metal from the vessel through the opening. There are no guide rolls, or other rolls that act on the continuous steel member, in the bath.
摘要:
Studies of Synergistic combinations of dsRNAs and anti-viral agents in the treatment of viral diseases indicates dsRNA, especially mismatched dsRNA, plays a powerful and versatile role as a core drug in combination therapy for human viral pathogens, notably for ARC and AIDS.
摘要:
A novel form of Rugged dsRNA with a unique composition and physical characteristics was identified with high specificity of binding to TLR3, which conveys an important range of therapeutic opportunities. Unlike the previous known antiviral Ampligen® (poly I, poly C12,U) the new and improved form (poly I, poly C30,U) has a reduced tendency to form branched dsRNA which results in increased bioactivity due to an increased ability to bind TLR3 receptor. Pharmaceutical formulations containing the new nucleic acid as active ingredients and methods of treatment are also provided. The invention also provides a description of the physicochemical properties of this novel form of Rugged dsRNA and a method for its preparation in substantially pure form. DsRNAs acting thru TLR3 receptor activation are potent antiviral compounds as well as anticancer agents; also through secondary immunomodulation they can enhance the bioactivity of vaccines and also treat autoimmune disorders.
