Perforated peptic ulcers in Belarus: past and present Prakiurusios pepsinës opos Baltarusijoje: praeitis ir dabartis
Mild variations of these statistics were observed before the 90s with an insignifcant tendency to grow from the second half of the 70s to the first half of the 80s. The Chernobyl accident in 1986 was not followed by any response. The incidence of perforated peptic ulcers almost doubled in the first half of the 90s, regional differences in the statistics appeared. These changes coincided with th...
متن کاملCorollary 4.18 Exp Np L(ir; Ir)
{ 15 { codewords. If any of the strings supplied by P k fails a multilinearity test, then V accepts P 3?k 's claim about whether or not w 2 L. It remains to show how V can test equality of two functions that are both 1=4-close to multilinear polynomials in K n X 1 ; : : :; X n ]. This can also be done using a well-known fact about polynomials. Schwartz's Lemma Sc80]: Two distinct polynomials in...
متن کاملA Combined Mid-IR/Near-IR Spectrometer
When analysts are faced with the decision of selecting either mid-IR (MIR) or near-IR (NIR) spectroscopy for materials characterization, the decision is usually based on the analytical, sampling, and/ or operational needs. For example, when the greatest analytical specificity is required or certain inorganic materials need to be measured, the choice favors MIR; whereas the need to keep an unsta...
متن کاملWhat Is an Ft-ir and an Ft-ir Spectrometer?
An FT-IR Spectrometer is an instrument which acquires broadband NIR to FIR spectra. Unlike a dispersive instrument, i.e. grating monochromator or spectrograph, an FT-IR Spectrometer collects all wavelengths simultaneously. This feature, called the Multiplex or Felgett Advantage, is discussed in detail on page 3. FT-IR Spectrometers are often simply called FT-IRs. But for the purists, an FT-IR (...
متن کاملNear-ir and Mid-ir Process Analysis — a Critical Comparison
Over the past several years, both near infrared (NIR) and mid infrared (MIR) spectroscopy have steadily gained acceptance as powerful methods for at-line and on-line analysis. These methods share the advantages of high speed, robust calibration, and low service requirements compared to more established process analytical techniques such as gas chromatography. However, despite their many similar...
