<p>This study was carried out to analyze the comparative analysis of efficiencies of artisanal fisheries in Ijebu Waterside of Ogun State. The objectives determined gross margin analysis; estimate the technical efficiencies of both the manually propelled technology (MPT) and motorized technology (MT) of artisanal fishery systems and determining the factors influencing the technical efficiencies of artisanal fisheries in the study area. A multistage sampling technique was used to select a total of 400 Artisans from the study area. Primary data were collected using structured questionnaire as interview guide, on the socio-economic characteristics, production inputs and output prices. The data collected were analyzed using both descriptive and inferential statistics. Stochastic production frontier model was used to estimate the technical, efficiencies of both motorized and manually propelled technologies in artisanal fishery system as well as the factors influencing the technical, efficiencies of the artisans.</p> <p>The results of the comparison of the MPT and (MT) revealed that the average income per month for MPT was N361,847.48 and the amount accruable per month for the MT was N560,755.57. The results of the comparison of catch efficiency and inefficiency function showed that in MPT, fishing gear, vessel length, number of crew/skippers, quantity of bait and battery were all significant at 5 percent probability level while for MT, fishing gear, outboard engine, battery and miscellaneous quantity were the significant factors. The mean catch efficiency of MPT was 0.92 compared to MT with 0.98. However, the comparison of the inefficiency shows that education, age, and household size are significant factors while education is significant factors in both MPT and MT respectively. The results of the returns-to-scale revealed that the parameters estimate of the MT was higher with 4.35 compared to MPT with 2.56.</p>

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.

Placebo Model

Research in recent years, especially in the analgesic field, has intensively studied the placebo effect and its mechanisms. It has been shown that physical complaints can be efficiently reduced via learning and cognitive processes (conditioning and expectancies). However, despite evidence demonstrating a large variety of physiological similarities between pain and itch, the possible transfer of the analgesic placebo model to itch has not yet been widely discussed in research. This review therefore aims at highlighting potential transfers of placebo mechanisms to itch processes by demonstrating the therapeutic issues in pharmacological treatments for pruritus on a physiological basis and by discussing the impact of psychological mechanisms and psychological factors influencing itch sensations.
