Modern NMR pulse sequences usually consist of a series of radiofrequcncy (rf) pulscs having orthogonal (quadrature) phases. While there are a variety of situations where pulse accuracy is important, 1 it is especially critical for solid-state multiple-pulse NMR.2 In fact, multiple pulse sequences developed for phase measurement excced the accuracy of traditional electronic phase measuremen t te...

Micro Small and Medium Enterprises (MSMEs) have a very strategic role in country. In addition to providing alternative employment, MSMEs also good staying power case of difficult economic emergencies. However, on the other hand there are many challenges that heavy by businesses belonging SMEs. Many same kind emerging increasingly tighter. Performance Measurement System (PMS) is control system b...

Background A significant number of pregnancies, particularly in women with previous histories of infertility, are associated with fetal abnormalities. Methods such as the nuchal translucency (NT) measurement enable us to identify more pregnancies with chromosomal abnormalities. MaterialsAndMethods This analytic cross-sectional study was performed in 446 pregnant women at 11-14 weeks gestation, ...

A comparison of electron beam parameters from a 1.6 cell S-band rf gun with Cu and Mg cathode at the SLAC Gun Test Facility are reported. The lower work function of Mg compared to Cu theoretically increases the quantum efficiency for a fixed laser wavelength and also increases the thermal emittance. Slice emittance measurements at low charge (15 pC) set an upper limit on the thermal emittance o...

Astigmatism’s defect has not yet been formulated in Physics and medical physics books theoretically. In this paper, we are trying to formulate the astigmatism’s defect. The results of formulation show that “the degree of astigmatism is negative reverse the distance that vision’s condition of astigmatism’s chart lines change conditions in dimness angle from dimness condition at infinite distance...
