Hard corns

Hard corns form on the outer aspects of the toes as a result of rubbing against shoes. 

Hard corns, soft corns and calluses may develop on and between the large and second toe as a result of pressure from shoes. 

Shrewsbury et al. (1942) found in studies on the stability of hog fat that the soft fat (peanut-fed, iodine munber 73-80) was consistently less stable than the hard (corn-fed, iodine number 58-60) both fresh and after frozen storage. However, there was more variation in the keeping time of hard fats from different lots of pork than in the keeping time of hard versus soft in any one lot. Peroxide values for fats extracted from the meats after freezer storage for 12 to 16 months were low and showed no significant differences between hard and soft fats. Brady et al. (1946) and Palmer et al. (1953) showed positive correlation between the softness of the fat and the susceptibility to rancidity of bacon and frozen ground pork, respectively. 

Surface crustation is caused by sucrose crystallization. It is characterized by hard white spots on the surface. It is remedied by the use of corn sirup solids and larger levels of hydrocolloids. During freezing in a continuous freezer there is ice separation caused by centrifugal separation of small ice crystals. Increase in mix viscosity by use of hydrocolloids inhibits this action. 

This optimization method, which represents the mathematical techniques, is an extension of the classic method and was the first, to our knowledge, to be applied to a pharmaceutical formulation and processing problem. Fonner et al. [15] chose to apply this method to a tablet formulation and to consider two independent variables. The active ingredient, phenylpropanolamine HC1, was kept at a constant level, and the levels of disintegrant (corn starch) and lubricant (stearic acid) were selected as the independent variables, X and Xj. The dependent variables include tablet hardness, friability, volume, in vitro release rate, and urinary excretion rate in human subjects. 

Xylan occurs in practically all land plants and is said to be present in some marine algae.6 In both wide botanical distribution and abundance in nature it closely follows cellulose and starch. It is most abundant in annual crops, particularly in agricultural residues such as corn cobs, corn stalks, grain hulls and stems. Here it occurs in amounts ranging from 15 to 30%. Hard woods contain 20 to 25% xylan while soft woods contain 7 to 12 %. Spring wood has more pentosan than summer wood. 7 Low strength vegetable fibers of commerce such as jute, sisal, Manila... 

Following dialysis and treatment by SEC, the sample extracts were solvent exchanged into sterile DMSO. Subsequently, four rainbow trout Oncorhynchus mykiss [RBT]) were placed in each of seven tanks (each tank is considered as a treatment and a replicate is an individual fish within a tank) in 18 °C well water (280 mg hardness as CaCOs) using flow-through conditions. RBT were fed once daily throughout the study. Following a 48 hour acclimation, RBT were injected interperitoneally with 100 pL of a 1 1 mixture of an SPMD extract or appropriate controls in DMSO or corn oil. Controls included non-deployed SPMD extracts, SEC blanks, and DMSO blanks. The same injection procedure was repeated 6 days later. RBT were sacrificed 11 days after initial exposure to the extracts, and the plasma, liver, gills, and brain were immediately removed from each fish and maintained at -80 °C until assayed. 

The effect, though not insignificant, is hardly dramatic. Taking corn and castor oils as examples, a ten-fold increase in viscosity has only led to a 30% increase in the acoustic pressure needed to bring about cavitation.

A combustion tube of either Jena hard glass or Corning 172 is constructed similar in design to that used for the preparation of rhenium pentachloride (synthesis 62). The pentachloride is prepared in the manner previously described and sublimed into the bulb D. The chlorine is then turned off, and the train swept out with nitrogen. When all chlorine has been displaced, the pentachloride is... 

Two of these ketones, 2-heptanone and 2-octanone, have been identified among the thermal decomposition products of corn oil, and their quantities were found to increase when corn oil was oxidized in the presence of zein (4). The effect of an increased surface area for reaction between zein and corn oil during extrusion is hard to determine from these data. 

Teosinte Zea mexicana, wild ancestral corn from Mexico and Central America. The seeds are not united on a cob. Rather, the female inflorescence (the ear) consists of a single row of six or more seeds, each of which contains a hard, flinty endosperm, like popcorn, covered by a tough shell. 

Zein is a vegetable protein obtained from corn gluten meal. Pure zein powder is odourless, tasteless, hard and water-insoluble. Since it is edible, it finds applications in processed foods and pharmaceuticals, in competition with chitosan and chitin.
