The Ameliorating effect of uncooked beans diet in CD-1 mice

Beans contain serotonin and its precursor, 5-Hydroxytryptophan which have neurobehavioral actions on memory, anxiety, mood and pain. This study was therefore, designed to investigate the ameliorating effect of uncooked beans on pain sensation using three groups of Swiss white mice (control and test) weighing 18g-35g (n=10 each).The control group received normal rodent chow, while the test group received 50g of uncooked beans in 50g of rodent chow per day and serotonin precursor (5HTP) (0.2mg/50g w/w) diet. Water was given adlibitum while daily food and water intake, as well as body weight changes, were monitored during the 30-day study. The formalin tests were used to assess pain sensation. The results showed that in the formalin test, the frequency and duration of paw attention in both phases of the test was significantly lower (P< 0.05) compared to the control group. The duration and frequency of paw licks (P<0.05) was also significantly lower in the uncooked beans diet and serotonin precursor group compared to the control. Therefore, consumption of uncooked beans diet may decrease pain sensation.    Â

The Effect of Water Storage on the Bending Properties of Esthetic, Fiber-Reinforced Composite Orthodontic Archwires

Objective: To study the effect of water storage on the bending properties of fiber-reinforced composite archwires and compare it to nickel-titanium (NiTi), stainless steel (SS), and beta-titanium archwires. Materials and Methods: Align A, B, and C and TorQ A and B composite wires from BioMers Products, 0.014-, 0.016, and 0.018-inch, and 0.019 × 0.025-inch NiTi, 0.016-inch SS, and 0.019 × 0.025-inch beta-titanium archwires were tested (n  =  10/type/size/condition). A 20-mm segment was cut from each end of the archwire; one end was then stored in water at 37°C for 30 days, while the other was stored dry. The segments were tested using three-point bending to a maximum deflection of 3.1 mm with force monitored during loading (activation) and unloading (deactivation). Statistical analysis was completed via two-way analysis of variance with wire and condition (dry and water-stored) as factors. Results: In terms of stiffness and force delivery during activation, in general: beta-titanium was \u3e TorQ B \u3e TorQ A \u3e 0.019 × 0.025-inch NiTi and 0.016-inch SS \u3e Align C \u3e 0.018-inch NiTi \u3e Align B \u3e 0.016-inch NiTi \u3e Align A \u3e 0.014-inch NiTi. Water exposure was detrimental to the larger translucent wires (Align B and C, TorQ A and B) because they were more likely to craze during bending, resulting in decreased forces applied at a given deflection. Align A and the alloy wires were not significantly (P\u3e .05) affected by water storage. Overall, the alloy wires possessed more consistent force values compared to the composite wires

The Magnitudes of Economic and Non-Economic Factors on the Demand for U.S. Domestic Air Travel

The primary purpose of this study is to analyze air carriers’ behavior in capturing market share by examining the economic factors affecting passenger behavior toward air travel. This study also examines non-economic factors such as seasonality, unexpected events (9/11 attack), mergers, and trends. Because the airlines included in this study compete with each other, seemingly unrelated regression estimation (SURE) is used to estimate the parameters of the demand models which have correlated error terms. The economic and statistical relationship of the factors with air passenger miles provides valuable information to understand the nature of the demand for the U.S. air passenger industry. In examining demand determinants, this study concludes that air fare, income, seasonality, and mergers play significant roles in determining the demand for air passengers

Behavior of Steel–Concrete Composite Beams with Corroded Shear Studs Under Negative Bending Moment

The behavior of corroded steel–concrete composite beams under hogging moment was studied by experimental investigation and theoretical analysis. A total of eight specimens, six of which had corroded shear studs, were tested. The corrosion rate of studs ranged from 0 to approximately 50%. The constant-current accelerated corrosion method was adopted to accelerate the corrosion process. The loading test results indicated that the bending capacity of the corroded beams decreased slightly with increasing corrosion ratio of the studs. The corroded beams also exhibited an obvious decrease in bending rigid stiffness and increase in the slip between the steel beam and the concrete slab. An analytical model was developed to study the steel–concrete composite beams with corroded studs under hogging moment. It is shown that the analytical model is able to predict the test results with reasonable accuracy
