background: the effectiveness of low power lasers on incisional wound healing, because of confl icting results of previous studies, is uncertain. therefore, the aim of this study was to evaluate the effects of low-level helium-neon (he-ne) laser irradiation on wound healing in rat’s oral mucosa. materials and methods: sixty-four standardized incisions were carried out on the buccal mucosa of 32...

For vibration testing, discrete types of scanning laser Doppler vibrometer (SLDV) have been developed and have proven to be very useful. For complex structures, however, SLDV takes considerable time to scan the surface of structures and require large amounts of data storage. To overcome these problems, a continuous scan was introduced as an alternative. In this continuous method, the Chebyshev ...

With the development of new generation technology and the low-carbon economy, the smart low-carbon city has become one of the academic hotspots. Many studies on it have begun; however, the dynamic mechanism is rarely involved. Therefore, this paper uses the Technique for Order Preference by Similarity to an Ideal Solution (TOPSIS) method to creatively take a quantitative study on a Chinese smar...

Manipulating the flow of energy in nanoscale and molecular photonic devices is of both fundamental interest and central importance for applications in light energy harvesting optoelectronics. Under erratic solar irradiance conditions, unregulated power fluctuations in a light-harvesting photocell lead to inefficient energy storage in conventional solar cells and potentially fatal oxidative dama...

Abstract. Mechanical efficiency analysis is a fundamental phase in the design of Power Gear Trains (PGTs) transmissions. This paper presents a methodology for computing the mechanical efficiency of Epicyclic Gear Trains (EGTs). A novel feature of this methodology is the capability to take into account load dependent power losses and inertia effects. Finally, the paper describes an apparatus use...

We present the redesign and improved performance of the laser terahertz emission microscope (LTEM), which is a potential tool for locating electrical failures in integrated circuits. The LTEM produces an image of the THz waves emitted when the circuit is irradiated by a femtosecond laser; the amplitude of the THz emission is proportional to the local electric field. By redesigning the optical s...

[Purpose] We report the case of a breast cancer patient with superficial thrombophlebitis treated with low-level laser therapy. [Case] The patient was a 66-year-old women who developed superficial thrombophlebitis in the left upper limb after chemotherapy. She was administered 6 sessions of low-level laser therapy. [Result] Her pain score decreased by 8 points. Her scores on the Patient and Obs...

PURPOSE To investigate the effectiveness of low-level laser therapy (LLLT) on gastrocnemius muscle morphology and Myod immunoexpression in a model of dorsal burn in rats. METHODS Sixteen male Wistar rats were distributed into two groups: control group (CG): rats submitted to scald burn injury without treatment and laser treated group (LG): rats submitted to scald burn injury and treated with ...

conclusions accordingly, laser therapy in our protocol seemed to affect some of the nerve growth parameters, mostly on motor rather than sensory fibers. results in the two -point discrimination- test, there was no significant difference between the two groups in the thumbs but a significant improvement was observed in the index finger of the lt group. improvement of muscular examinations such a...

This paper presents a fully differential opamp desing based on the switched-opamp approach. The common mode feedback of the proposed opamp only works on the output stage in order to allow a fast turn-on. The opamp was designed in a 0.35 m CMOS technology and is able to operate from a single 1V supply.
