A solid material is treated, the chemical structure of which defines reactive protogenic hydrophillic functions accessible to gases, by applying at least one gas stream (3) onto at least one microdispersion (5) of at least one grafting reagent RX produced on the solid material, R being a hydrophobic group, X being chosen so that HX is volatile under normal conditions, R and X being chosen so that the reaction of RX on the hydrophillic functions produces covalent grafting of the hydrophobic group R with formation of the compound HX, it being possible for the reaction to be carried out in a solid / gas heterogeneous medium on all the reactive hydrophillic functions accessible to gases and only on these. The invention extends to the hydrophobic solid material obtained, and is applicable to the obtaining of natural or artificial fibrous or inorganic structures impermeable to water and to aqueous solutions and / or absorbing fats.

The invention relates to a method of identifying an individual nucleotide, comprising (a) contacting the nucleotide with a transmembrane protein pore so that the nucleotide interacts with the pore and (b) measuring the current passing through the pore during the interaction and thereby determining the identity of the nucleotide. The invention also relates to a method of sequencing nucleic acid sequences and kits related thereto.

The present invention describes an extremely effective, simple, novel, inexpensive, safe and quick method to treat both acne and warts, each with a different etiology and different clinical symptoms, by topically applying an effective amount of one or more polyvalent metal compounds. The polyvalent metal compounds include, but are not limited to, bismuth compounds, zinc compounds, magnesium compounds, aluminum compounds, calcium compounds, copper compounds, titanium compounds, manganese compounds, chromium compounds, barium compounds and iron compounds. The present invention can also be applied to the treatment of rosacea. The present invention can also be employed to prevent scarring and to facilitate healing or elimination of the scars once formed.

Eluting reagents and methods for isolating DNA from biological materials are provided.

Processes for isolating, amplifying, and characterizing DNA from biological materials are provided. DNA is isolated by contacting a biological material on a solid support which is preferably pre-treated with a lysing reagent. The isolation process is simple and efficient and provides a source of purified DNA without the use of harmful organic solvents such as urea and guanidine-based solvents. The purified DNA and remaining fractions of biological material may be characterized or amplified as necessary.

A window protection structure for a building including novel structure for affixing a sheet of protection material over the window opening. The sheet material is cut to the size of the window opening in the building, and holes are formed therein. U-shaped clips are slid onto an upper edge of the sheet material, and a plurality of brackets are provided with a pair of holes formed therein. Cords loops are secured through the holes in the brackets. The brackets are adapted for receipt by the interior of the window and the cords are threaded to the exterior of the window. The cord loops are threaded through the holes in the sheet material. A bungee cord is then used for securing the ends of the cord loops, whereby the sheet material is held firmly against the window.

The present invention relates to a method capable of detecting proliferative bacteria in food and beverage, particularly acid or neutral beverage at low cost within a short time, a detection kit which enables simple measurement, and a technology for examination of harmful bacteria in food and beverage with respect to a method for rapid determination of proliferation properties of bacteria capable of producing guaiacol in food and beverage. There is disclosed a method for detecting bacteria capable of producing guaiacol, which comprises culturing or incubating a culture solution containing a specimen for a predetermined time in the presence of vanillic acid, and measuring the produced guaiacol by qualitative or quantitative analysis. Also there is disclosed a kit for detection of bacteria capable of producing guaiacol, comprising a container, and an acid or neutral culture medium containing a vanillic acid substrate for production of guaiacol, which is contained in the container and also sterilized and sealed. Furthermore there is disclosed a method for rapid determination of proliferation properties of bacteria capable of producing guaiacol in food and beverage, which comprises incubating a sporophyte of spore-forming bacteria capable of producing guaiacol for a predetermined time in the food and beverage in the presence of vanillic acid, and measuring the produced guaiacol by qualitative or quantitative analysis.

A method for determining an optimal voltage pulse for programming a flash memory cell, the optimal voltage pulse being defined by a voltage ramp from a non-zero initial voltage level during a programming duration, wherein the method takes into account a set of parameters including a programming window target value and a drain current target value of the memory cell.
