The study showed that the highest activation percentage of the insecticides (Spinosad, Emamectin and the mixture of the insecticides) were obtained when mixed with silica gel for the larvae grown on the corn (2.266, 1.255 and 1300 respectively), while the lowest activation percentage (Antagonism) was recorded for the mixture of each of the Spinosad and Emamectin separately with the gypsum of the larvae grown on the wheat giving 0.776 and 0.989, respectively. The highest of synergism percentage was for silica gel when mixed with each of Spinosad, Emamectin and the mixture of insecticide against the larvae which grown on corn reached 2.014, 1.178 and 1.256 respectively; the lowest of synergism percentage was for gypsum when mixed with the Spinosad and the insecticide mixture against larvae grown on the wheat, which reached 0.454 and 0.918 respectively, while the ratio was 0.841 for the Emamectin insecticide when mixed with the limestone against the larvae which grown on wheat. For the percentage of potentiation, the study showed that the treatment of larvae grown on wheat and corn which treated with a mixture (silica gel and Spinosad insecticide) gave the highest percentage of the potentiation of the pesticide reached 0.41 and 0.252 respectively, and the lowest potentiation percentage of larvae on wheat and maize was recorded for gypsum with the mixture of insecticides reaching 0.082 and 0.016 respectively.

Tracy and Doremus have demonstrated chemical bonding between bone and hydroxylapatite with transmission electron microscopy. Now researchers ponder how to improve upon this bond in turn improving the life expectancy and biocompatibility of implantable orthopedic devices.This report focuses on a study of the- chemical influences on the interfacial integrity and strength. Pure hydroxylapatite (HAP), magnesium doped HAP, strontium doped HAP, bioglass and medical grade titanium cylinders were implanted into the tibial cortices of New Zealand white rabbits. After 12 weeks, the implants were retrieved for a scanning electron microscopy study coupled with energy dispersive spectroscopy.Following sacrifice and careful retrieval, the samples were dehydrated through a graduated series starting with 50% ethanol and continuing through 60, 70, 80, 90, 95, and 100% ethanol over a period of two days. The samples were embedded in LR White. Again a graduated series was used with solutions of 50, 75 and 100% LR White diluted in ethanol.

Normal Adults

Electrodermal and electroencephalic responsivity to sound and to light was studied in 96 normal-hearing adults in three separate sessions. The subjects were subdivided into equal groups of white men, white women, colored men, and colored women. A 1 000 cps pure tone was the conditioned stimulus in two sessions and white light was used in a third session. Heat was the unconditioned stimulus in all sessions. Previously, an inverse relation had been found in white men between the prominence of alpha rhythm in the EEG and the ease with which electrodermal responses could be elicited. This relation did not hold true for white women. The main purpose of the present study was to answer the following questions: (1) are the previous findings on white subjects applicable to colored subjects? (2) are subjects who are most (or least) responsive electrophysiologically on one day equally responsive (or unresponsive) on another day? and (3) are subjects who are most (or least) responsive to sound equally responsive (or unresponsive) to light? In general, each question was answered affirmatively. Other factors influencing responsivity were also studied.
