Abstract: A method of treatment of a subterranean hydrocarbon-bearing reservoir, the reservoir comprising at least one porous and permeable rock formation, the reservoir being penetrated by a plurality of injection wells and one or more production wells, the injection wells sharing a common injection header for delivering an aqueous injection fluid to the injection wells, the method comprising: a. identifying a group of injection wells selected from the injection wells sharing the common injection header; b. determining a cumulative volume of the treatment stream that is to be supplied contemporaneously to all of the injection wells within the identified group; c. simultaneously transmitting the treatment stream only to the identified group of injection wells so as to inject the treatment stream into the reservoir, thereby treating the reservoir to improve the sweep efficiency of subsequently injected fluid.

Abstract: Antiviral and antifungal compositions comprise a ferrous salt and a plant extract of pomegranate rind, Viburnum plicatum leaves or flowers, tea leaves or maple leaves in aqueous solution.

Abstract: Antiviral and antifungal compositions comprising a mixture of a ferrous salt and an aqueous plant extract of pomegranate rind, Viburnum plicatum leaves or flowers, tea leaves or maple leaves are disclosed.

Abstract: Antiviral and antifungal compositions comprising a mixture of a ferrous salt and a plant extract of pomegranate rind, Viburnum plicatum leaves or flowers, tea leaves, or maple leaves in an aqueous solution are disclosed. The compositions are mainly used to prevent the growth of, or kill, viruses or fungi on surfaces. The compositions do not substantially affect bacterial viability as measured by colony forming ability.

Abstract: A method for testing for target bacteria involves adding bacteriophage to a sample to infect the bacteria in the sample; killing extracellular bacteriophage without killing phage-infected bacteria; amplifying bacteriophage remaining in the sample; and causing the bacteriophage to infect reporter bacteria and thereby produce an observable signal. The reporter bacteria are genetically engineered to have an indicator gene which on expression gives rise to a detectable signal, wherein expression of the indicator gene is initiated on bacteriophage infection of the bacteria.
