Flow Through

A system was developed to measure the streaming potential generated between the ends of a capillary by the flow of a fluid through the capillary. Zeta potential can be calculated from the streaming potential. Adequate sensitivity and reproducibility were achieved by making special electrodes: silver wires plated in KCl solution and embedded in agar, careful electrical shielding, and provision for reversal of flow through the capillary to minimize electrode errors. The apparatus was developed to measure streaming potentials generated by either RingerS's solution or blood in contact with capillaries made of different materials such as quartz, polyethylene, etc. An example of a determination using a quartz capillary is presented. interfaces; blood; salt solutions; glass; quartz Submitted on February 25, 1963

Insect Cold Hardiness

Use of the calorimetric and dilatometric methods for determination of ice in frozen tissues is criticized, and a method based on terminal melting points determined after various degrees of drying is proposed. The theoretical background of such a method lends support to it, and experimental work with gelatin is especially convincing. Use of the dehydration – melting point method on blood of Loxostege sticticalis gave results conforming in general to those obtained by other workers with calorimetric and dilatometric techniques, and also to those obtained with salt solutions. The amount of water that is bound is shown to be very low, as in mammalian, frog, and fish muscle. The possible influence of bound water in insect cold-hardiness is discussed and the conclusion is reached that it has little if any protective effect.
