This study explores the factors influencing customer eagerness to purchase energy-efficient appliances, a key component in the transition toward sustainable consumption. As environmental concerns grow and energy costs rise, consumers are becoming increasingly interested in appliances that reduce energy usage and lower long-term costs. The research highlights the roles of perceived behavioural control, price sensitivity, and environmental knowledge in shaping purchasing decisions by using SEM analysis. While consumers are drawn to the environmental and economic benefits of energy-efficient products, high upfront costs and limited awareness of long-term savings pose significant barriers. The findings suggests that environmental knowledge, perceived behavioural control, price sensitivity can enhance customer willingness by providing information on energy savings, offering financial incentives, and making energy-efficient appliances more affordable. This shift is critical for driving sustainable market growth and promoting eco-friendly behaviours in households and industries. [ABSTRACT FROM AUTHOR]

Objective: Tramadol hydrochloride has shown local anesthetic properties similar to lidocaine, apart from a central analgesic effect. The present study evaluated the effect of the administration of tramadol alone or in addition to 2% lidocaine, as supplementary intraligamentary injections. Methods: One hundred and five patients, with a failed primary inferior alveolar nerve block (IANB), were randomly allocated to one of the three supplementary intraligamentary groups: 2% lidocaine with 1:80,000 epinephrine; tramadol hydrochloride (50 mg/mL); and 2% lidocaine with 1:80,000 epinephrine plus tramadol hydrochloride. Patients received 1.2 mL doses (0.6 mL of each root). Patients reporting pain ≤54 on Heft Parker visual analogue scale (Heft-Parker VAS), were categorized as successful anesthesia. A finger pulse oximeter was used to measure the heart rates. The anesthetic success rates, gender, and type of tooth were compared using the Pearson chi-square test. The heart rates and age were statistically evaluated using the one-way analysis of variance test. The level of significance was set at 0.05 (p=0.05). Results: The initial IANB was successful in 31% of cases. There were significant differences in the anesthetic success rates of different supplementary intraligamentary injections (χ²= 33.6, p<0.001, df=2). The 2% lidocaine- plus-tramadol resulted in significantly higher success rates than the two groups. There were no significant changes in the baseline heart rates of all groups (p>0.05). Conclusion: The addition of tramadol to 2% lidocaine with 1:80,000 epinephrine, given as supplementary intraligamentary injection, can help in achieving successful anesthesia during the endodontic management of mandibular molars with irreversible pulpitis resistant to IANB injections.

Non-traditional machining methods like wire electric discharge machining (WEDM) appear to be an ideal choice for machining high strength super alloys like Inconel 706, because of their capability to generate intricate profiles with high accuracy. However, wire breakages are a common problem in the WEDM process and adversely affect the productivity, accuracy, and surface quality. Therefore, the aim of this work is to investigate and comprehend the phenomenon of wire breakage using Inconel 706 as work material and brass wire, diffused brass wire, and zinccoated brass wire as electrode materials. Six process parameters--pulse-on time, pulse-off time, peak current, spark gap voltage, wire feed rate, and wire tension--have been varied experimentally to determine their effect on the frequency of wire failure. According to the findings, the zinc-coated brass wire breaks with the lowest frequency when compared to the other two. Additionally, an ideal range of input variables has been proposed for efficient WEDM of Inconel 706 without unexpected wire breakages. This range can also be utilized for further research work related to modeling and optimization in WEDM of Inconel 706. [ABSTRACT FROM AUTHOR]
