The present invention relates to a method to inhibit bacteria from adhering to a submergible surface. The method contacts the submergible surface with an ionene polymer and a salt of dodecylamine in a combined amount effective to inhibit bacterial adhesion to the submergible surface. The present invention also relates to a method for controlling biofouling of an aqueous system. This method adds an ionene polymer and a salt of dodecylamine in a combined amount effective to inhibit bacteria from adhering to a submerged surface within the aqueous system. This method effectively controls biofouling without substantially killing the fouling organisms. The present invention also relates to compositions containing an ionene polymer and a salt of dodecylamine and useable in the above methods. The compositions comprise an ionene polymer and a salt of dodecylamine in a combined amount effective to inhibit bacteria from adhering to submergible or submerged surfaces.

The invention provides a solid TCMTB formulation for controlling the growth of at least one microorganism. The use of a solid TCMTB formulation, as compared to a liquid, minimizes user contact and is more readily packaged. A solid TCMTB formulation of the invention contains TCMTB adsorbed onto a water-soluble, salt carrier matrix, with the TCMTB present in an amount effective to control the growth of at least one microorganism, preferably in an aqueous system. Other microbicides and additives may also be incorporated into a solid TCMTB formulation of the invention. In a preferred embodiment, the formulation contains both TCMTB and one or more other microbicides (e.g., methylene bisthiocyanate (MTC)) and a water-soluble, salt carrier matrix. The TCMTB is adsorbed onto the water-soluble salt carrier matrix. The TCMTB and other microbicide are present in a combined antimicrobial amount effective for the control of at least one microorganism. A solid TCMTB formulation may be used in a wide variety of biocide applications. Accordingly, the invention also relates to a method for controlling the growth of at least one microorganism in a liquid, preferably aqueous, system. In particular, the method controls the growth of at least one microorganism in an aqueous system by contacting an aqueous system with a solid TCMTB formulation comprising TCMTB adsorbed onto a water-soluble salt carrier matrix in an amount effective to control the growth of at least one microorganism in the aqueous system.

Methods for controlling the growth of bacteria in ethanol fermentation systems with antibiotic alternatives, which can be nonoxidizing biocides, stabilized oxidizers, or any combinations thereof, are described. As an option, a process or composition of the present invention can include one or more polycyclic antibacterial peptides. The methods can provide improvements, such as increased ethanol yields with minimal carryover of biocide into co-products of the processes.

An all weather housing assembly for protection of electrical components includes a first housing having an open end and defining a first compartment for receipt therein of electronic components; a cover attached to the first housing for enclosing the first compartment, the cover further including a mounting structure for receiving and retaining a power source which structure is mounted on a side of the cover that is exterior to the enclosed first compartment; and a second housing having an open end and defining a second compartment that is dimensioned to cover and protect a power source when received and retained by the mounting structure of the cover, the second housing being connected to the first housing independent of the attachment of the cover to the first housing.
摘要:
Described herein are fragments of fibronectin and variants thereof that bind growth factors. Compositions containing such a fragment of fibronectin are therefore useful in sequestering growth factors, and complexes containing both a FN fragment and a bound, active growth factor can be used to deliver growth factors to a patient (e.g., to a wound on the patient's skin).

An extendable channel unit such as molding unit (21) has a pair of telescopically arranged relatively extendable conduits (55, 75) with a conductor (22) interconnected in conductive relation between the conduits, with an intermediate section (137) of the conductor effective to accommodate the relative extension of the conduits. The intermediate section may include a sinuous configuration (133) or expandable coils (139). The channel unit may be installed along a wall (145) or other surface for decoratively covering the installation of the conductor for connection with an operated device (153). The channel unit may be installed into an extendable ramp (163) when installed along a floor, such as within a doorway (171). Two joints (308, 310) provide freedom of rotation about the conductor axis on opposed sides of an angled joint (312) that provides freedom of rotation about an axis disposed at a 45° angle to the axis of the conductor. This combination permits the unit to be configured to pass around both inside and outside corners, as well as to form upward and downward right angles along a straight wall.

A composition for minimizing biological and/or colloidal fouling is described, which includes an anionic antiscalant and a cationically charged biocide. Further, a method of controlling fouling is described and achieved by introducing a formulation of the present invention into an aqueous system which uses a separation membrane. The compositions used in the present invention are compatible with such separation systems and preferably prevent membrane fouling.
摘要:
The driver is disclosed for a surgical micro-suturing stapling system which does not require the use of a staple bending anvil tha must be retracted after the staple is implanted. The surgical microstapler system utilizes a unique stapler head comprising a staple magazine having a series of staples attached to and supported by a surrounding frame, apparatus for advancing the staple magazine so as to position its leading staple in a predetermined dispensing position, and staple driving apparatus for implanting the leading staple into the tissue through the ejection slot. The stapler head is adapted to be connected to the driver which provides the driving force required to cause the staple driving apparatus to separate the leading staple from the magazine and implant it into the tissue to be sutured. The driver offers the advantage that can cause the staple driving apparatus to implant a staple at a velocity in excess of the ability of tissue to respond dynamically under the force of a staple being implanted. The driver also is manually powered, can be operated by one hand of the surgeon, has little or no recoil, is simple in operation, and is readily attached to or detached from the stapler head.
摘要:
A surgical microstapler is disclosed which does not require the use of a staple bending anvil that must be retracted after the staple is implanted. The surgical microstapler utilizes a stapler head comprising a staple magazine that consists of a series of staples attached to and supported by a plurality of frame members. The stables have a predetermined shape characterized by a spine portion and two opposite legs. The staples and frame members are formed as part of a sheet metal continuum and are joined by a plurality of tabs which coact with the frame members to hold the staples in proper spaced relationship within the magazine. The stapler head also comprises means for advancing the magazine so as to position its leading staple in a predetermined dispensing position in line with an ejection slot through which the staple is ejected and inserted into tissue, and staple driving means for implanting the leading staple. The leading staple is held to the magazine at its spine as it is engaged by the staple driving means. The staple driving means is shaped so as to contact the opposite legs of the staple and to deflect them downward following a curved trajectory with closely resembles the motion of a surgeon's suturing needle. The stapler head is adapted to be connected to a driver which provides the driving force required to cause the staple driving means to separate the leading staple from the magazine and implant it into the tissue.
