On the basis of previous experimental research, the nonlinear finite element analysis of the eccentric in-plane beam-wall joint is made with nonlinear bond-slip constitutive relation between steel and concrete. The mechanical behavior of the joint is studied in detail, and parametric analysis is carried out for mechanical behavior of the joint. Results of experiment and nonlinear analysis proved that: the important guarantee for mechanical behavior of the eccentric in-plane beam-wall joint is macro resistance capability, which is a precondition of local force transmission of the joint. In addition, the length of beam plunging wall, eccentricity of the joint and the stirrup ratio of beam within wall are the main factors influencing on mechanical behavior of the joint.

Boarhounds are hunting dogs bred for hunting wild boar, including terriers, dachshunds, and hounds. Hunt trials evaluate the individual hunting potential and trainability of the boarhounds in ten different competitions. The aim of this study was to determine the factors influencing the hunt trials for boarhounds in a large cohort of hunting dogs. The analysis was conducted based on the results of hunt trials for boarhounds conducted in 2005–2015. The database contained 1867 individuals belonging to 39 breeds. Effects of sex, age, breed group, and breed were estimated by non-parametric analysis of variance. Sex influenced (p < 0.01) the total score, and in almost all competitions dogs performed better than bitches. Age affected (p < 0.01 or p < 0.05) all competitions, indicating that the dogs perform better with age. The results analyzed by the breed group showed that the dachshunds performed better in courage (p < 0.01) and searching (p < 0.05). Breed influenced (p < 0.01) almost all scores except obedience and tracking on the lead. The best performing breed was Alpine Dachsbracke. In conclusion, all analyzed factors influenced the results of the hunt trials. The factors with the largest impact were breed and age, which reflect both the hunting potential and the level of training of the boarhounds.

This study identifies, categorizes and examines the factors influencing customers in their decision to engage in financial transaction with commercial banks. Primary data were elicited from bank customers across Six States in Southwest, Nigeria. The data collected from the randomly sampled respondents were analysed using descriptive statistics and Kruskal-Wallis H ranking test. The findings from non-parametric analysis of the factors using Kruskal-Wallis ranking technique show that, respectively, timeliness of operations, internet service and safety of transactions are of great values to bank customers. It is important for banks to internalize the identified factors in order to increase patronage and efficiency of fund mobilization.

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.
