Aim: To compare the operating time, postoperative pain, edema, trismus, and patient acceptance following surgical removal of impacted third molar using piezosurgery and conventional rotary technique.
Materials And Methods: About 42 patients with impacted mesioangular mandibular third molars were included in this study. Subjects are divided into two groups: group I (treated with conventional rotary technique) and group II (treated with piezosurgery). Duration of surgery, pain, trismus, and swelling were assessed. The patients were evaluated on the 1st, 3rd, and 7th postoperative days.
Results: Postoperative pain, trismus, and edema were reduced with piezosurgery compared with conventional technique. Even though the duration of time was longer with piezosurgery, patient comfort was found to be better.
Conclusion: Piezosurgery is a meticulous and innovative ultrasonic technique with selective bone cutting and better postoperative outcomes. However, it is expensive, and the operating time is prolonged.
Clinical Significance: Piezosurgery is an alternative in the surgical removal of third molars as it ensures precise and selective cutting, with no injury to the surrounding soft tissues. Postoperative outcome and patient acceptance are improved with piezosurgery.

Alzheimer's disease (AD) is the leading cause of dementia worldwide, and the development of early screening methods can address its significant health and social consequences. In this paper, we present a rotary-valve assisted paper-based immunoassay device (RAPID) for early screening of AD, featuring a highly integrated on-chip rotary micro-valve that enables fully automated and efficient detection of the AD biomarker (amyloid beta 42, Aβ42) in artificial plasma. The microfluidic paper-based analytical device (μPAD) of the RAPID pre-stores the required assay reagents on a μPAD and automatically controls the liquid flow through a single valve.

BACKGROUND Dental caries removal is conventionally done using carbide burs, but non-metallic polymer burs have recently been developed with the aim of being more selective and causing less pain. The objective of the study is to evaluate and compare the effectiveness of caries removal, time taken, and patient compliance during restorations using smart bur and carbide burs in pediatric patients. MATERIAL AND METHODS A clinical study was designed and conducted at the Pedodontics Outpatient Department, with a focus on 40 children between 6 and 12 years old, who were split into 2 groups consisting of 20 children each: group 1, using a carbide conventional rotary bur, and group 2, using a smart bur.

Unbalance faults are among the common causes of interruptions and unexpected failures in rotary systems. Therefore, monitoring unbalance faults is essential for predictive maintenance. While conventional time-invariant mathematical models can assess the impact of these faults, they often rely on proper assumptions of system factors like bearing stiffness and damping characteristics.

In response to the rotary ploughing equipment in the stubble land to implement protective operations, the stubble is large in number and strong in toughness, not easy to crush, resulting in rotary ploughing equipment to produce entanglement and increased resistance to rotary ploughing and other issues. In this study, researchers designed a bionic rotary tillage blade (B-RTB) based on the bionic structural equations of the Marmota claw. A straw-soil complex shear performance test was conducted to investigate the effect of straw on soil shear strength.

This paper presents a novel and comprehensive control framework for the Rotary Inverted Pendulum (RIP), focusing on a hybrid control strategy that addresses the limitations of conventional methods in nonlinear and complex systems. The proposed controller synergistically combines an Optimized Fuzzy Logic Controller (OFLC) with Sliding Mode Control (SMC), leveraging the strengths of both techniques to achieve superior performance. The integration of Particle Swarm Optimization (PSO) into the OFLC significantly enhances its adaptability and precision, while the SMC law provides robust disturbance rejection and system stability.
