This study aims to determine the factors that influence production and the magnitude of the factors that affect the production of Pepper in Kongkomos Village, Basidondo District, Tolitoli Regency. The time of research and data collection was carried out from October to November 2018. The determination of the purpose and location was determined intentionally, based on the consideration that Kongkomos Village had the highest production in Tolidoli, Basidondo Regency. The results showed that the factors influencing Pepper Farming Production were variable land area (X1), pesticides (X2), urea fertilizer (X3) and labor (X4). Variable X (land area, pesticides, urea fertilizer and labor) simultaneously has a significant effect on the Y variable (pepper production) with a value of R2 = 0.97, which explains that the contribution of variable X (land area, perticide, urea fertilizer, labor) ) to increase the fall of the variable Y (pepper production) by 97% while the remaining 3% is caused by other factors outside the production function model analyzed. From the results of the persial test it was revealed that the variables X1 (land area) 2,968, X2 (pesticides) 2,817, X3 (urea fertilizer) 4,488 and X4 (labor) 3,104 were greater than the value of t-table 2.78 which meant that the variable X1 (area land)), X2 (pesticides), X3 (urea fertilizer) and X4 (labor) have a significant effect on pepper production.

The objective of this study was  to estimate input demand and output supply for catfish growth out.  The study was conducted in Tulung Agung regency, East Java from August to December 2002. Data were analyzed statistically  by profit function model, using Three-Stages Least Square estimation.  The results of this study showed that the catfish price was elastic and responsive to the changes of catfish  seed and  feed prices, but inelastic to the  changes of human labor.  The catfish price had positive effects on variables input demand and output supply.  These positive effects were more significance than the negative effect of  variables input price

AbstractAn increasing emphasis on surface and groundwater quality and food safety may result in some form of pesticide regulations. A restricted profit function model of Georgia agriculture is used to examine the short-run effects of 2 and 5 percent reductions in all pesticides. Point estimates of short-run impacts, along with their 90 percent confidence intervals are presented.

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.

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.
