New separation methods termed Enhanced Partitioning Fractionation (EPF) and High Osmotic Pressure Chromatography (HOPC) are described. The HOPC method involves passing large amounts of concentrated polymer solutions over porous material in a packed column. The concentration is high enough to allow for polymer chain overlap and to generate high osmotic pressures with respect to the porous material. The resulting high osmotic pressure causes increased separation of the polymer sample based on molecular size. The higher molecular weight components are concentrated in the initial fractions of eluent collected, whereas lower molecular weight components are concentrated in later fractions. The molecular weight of each fraction decreases with each successive fraction of eluent. The method is applicable to a wide variety of polymers and provides significant performance advantages to conventional preparative scale GPC.
A method of production for dehydrated pumpkin slices is described. The method involves the dehydration of sliced pumpkin, followed by the rehydration of the slices. Seasoning and condiments are then applied for flavor. Then, the slices of pumpkin are dehydrated or dried naturally in a greenhouse a second time. The result of this process is a seasoned product tit for human consumption having a long shelf life. The method produces a healthy food product from materials often left unused in modern cuisine. The slices may be packaged similar to the way in which beef jerky is packaged and sold, as a snack product.
A method for relieving the symptoms of arthritis externally is described. The method involves the use of sliced ginger root, moxa, produced from mugwort, and a needle. Freshly cut ginger roots are sliced into slices approximately one centimeter thick and placed on the skin near the area afflicted with arthritis. The moxa, preferably in the form of a rolled moxa cigar, is stood vertically atop the slice of ginger and ignited. The moxa cigar is permitted to burn down to the surface of the slice of ginger, heating the ginger as well as the skin of the patient. Due to the heat, the skin of the patient is blistered. After a duration of time, the ginger slice is removed from the skin, the blister is punctured with a needle, and allowed to heal. This process leaves the patient free of arthritis-induced pain or similar symptoms.
