摘要:
A composite binder comprises: one or more Class F fly ash materials, one or more gelation enhancers, and one or more hardening enhancers, wherein each of the one or more Class F fly ash materials comprises 15 wt. % or less calcium oxide, and wherein the composite binder is a Portland cement-free binder for concrete. Also provided are Geopolymer Composite Cellular Concretes (GCCCs) including the composite binder and methods of making these GCCCs.
摘要:
The embodiments of the inventions disclosed in this application develop a 'protection' electric, magnetic or electromagnetic field or fields which are either superimposed upon an ambient field which is detrimental to the health of living systems, or incorporated into the electrical circuit of the device which is generating the detrimental field. Either arrangement is successful in 'confusing' living cells, and thereby reducing the harmful effects of the otherwise detrimental field.
摘要:
Methods and apparatus are described to inhibit the adverse health effects of ischemia, hypoxia, anoxia or other stress by the application of a time-varying field to the region of the affected organ(s) for a short period of time (of the order of 20 minutes). A "field" means a time-varying electric field, a time-varying magnetic field and/or a radiating electromagnetic field. The exposure can be started up to two or more hours in advance of the ischemic event or other stress causing event. Inhibition occurs even if the field is applied after the onset of ischemic or anoxic stress.
摘要:
Complex viruses are assembled from simple protein subunits by sequential and irreversible assembly. During genome packaging in bacteriophages, a powerful molecular motor assembles at the special portal vertex of an empty prohead to initiate packaging. An aspect of the invention relates to the phage T4 packaging machine being highly promiscuous, translocating DNA into finished phage heads as well as into proheads. Single motors can force exogenous DNA into phage heads at the same rate as into proheads and phage heads undergo repeated initiations, packaging multiple DNA molecules into the same head. This shows that the phage DNA packaging machine has unusual conformational plasticity, powering DNA into an apparently passive capsid receptacle, including the highly stable virus shell, until it is full. These features allow for the design of a novel class of nanocapsid delivery vehicles.
摘要:
A geopolymer composite binder is provided herein, the composite binder including (i) at least one fly ash material having less than or equal to 15 wt % of calcium oxide; (ii) at least one gelation enhancer; and (iii) at least one hardening enhancer having a different composition from a composition of the at least one fly ash material.
摘要:
Methods and apparatus for inhibiting the adverse effect of an ambient time varying field having an electric component and/or a magnetic component on a living system. To provide protection, the field to which the system is exposed is caused to be one wherein at least one of the characteristic parameters of said field to which the living system is exposed is changed within time intervals of less than 10 seconds. The strength of the field to which the living system is to be exposed is controlled as a function of the strength of the ambient field. Living systems which are benefitted include humans.
