Distance Corrections

281
To achieve precise distance measurements, especially in surveying and construction, certain corrections must be applied to account for potential sources of error like the standardization errors, temperature variations, and slope adjustments.Standardization error emerges when measurement equipment undergoes changes, such as wear, repairs, or weather impacts. To address this, surveyors compare the equipment’s readings to a standard. This process identifies any deviation that might lead to...

Single-stage Dynamic Reanimation of the Smile in Irreversible Facial Paralysis by Free Functional Muscle Transfer

106.4K
The use of the masseteric nerve as donor nerve represents a single-stage alternative to the criterion standard two-stage procedure of cross-facial nerve grafting and free muscle transfer in facial paralysis. We provide a detailed description to safely perform this technique with a gracilis muscle transfer and discuss indications and...

Power Factor Correction

491
The power transmission to a factory involves the transfer of apparent power, a combination of active and reactive power. The power factor measures how effectively electrical power is converted into useful work output. The ratio of the real power (KW) that does the work to the apparent power (KVA) supplied to the circuit.

Binocular Dynamic Visual Acuity in Eyeglass-Corrected Myopic Patients

3.2K
The present research demonstrates a method to accurately examine dynamic visual acuity (DVA) in myopic subjects with eyeglass correction. Further analysis indicated that the closer the refraction state to emmetropia, the better the eyeglass-corrected binocular DVA is at both 40 and 80 degrees per...

NMR Spectrometers: Resolution and Error Correction

1.0K
When magnetic nuclei in a sample achieve resonance and undergo relaxation, the signal detected in NMR is an approximately exponential free induction decay. Fourier transform of an exponential decay yields a Lorentzian peak in the frequency domain. Lorentzian peaks in an NMR spectrum are defined by their amplitude, full width at half maximum, and position, where the peak width is governed by the spin-spin relaxation time alone. In real experiments, however, the applied magnetic field is rendered...

Area of Science:

  • Ophthalmology
  • Refractive Surgery
  • Corneal Surgery

Background:

  • Small Incision Lenticule Extraction (SMILE) is a modern, flapless refractive surgery for myopia and myopic astigmatism.
  • SMILE offers benefits over LASIK, including improved corneal biomechanics and reduced dry eye complications.
  • Concerns exist regarding SMILE's precision in correcting astigmatism, with reported undercorrections.

Purpose of the Study:

  • To review factors impacting astigmatism correction accuracy in SMILE procedures.
  • To discuss methods for enhancing refractive outcomes in SMILE surgery.

Main Methods:

  • Literature review of studies on SMILE and astigmatism correction.
  • Analysis of identified factors affecting refractive outcomes.
  • Evaluation of techniques to improve SMILE precision.

Main Results:

  • Several factors influencing astigmatism correction in SMILE have been identified in existing literature.
  • Potential techniques to optimize refractive results are discussed.

Conclusions:

  • Understanding factors affecting astigmatism correction is crucial for successful SMILE outcomes.
  • Further refinement of techniques can improve the precision of astigmatism correction with SMILE.
