Imaging spectrum of mesenteric masses
Abdominal Radiology, 2020Mesenteries are extensions of the visceral and parietal peritoneum consisting of fat, vessels, nerves, and lymphatics. Mesenteric masses have a wide differential diagnosis with neoplastic, infectious, or inflammatory etiologies and can either be solid or cystic. Imaging features are critical for the diagnosis.

Physical Review, 1960
It is assumed that the $\ensuremath{\pi}$-baryon interactions are universal and the $K$-baryon interactions account for the large mass differences between baryons. If further all baryon spins are \textonehalf{} and $K$ spin is zero, ($\ensuremath{\Sigma}, \ensuremath{\Lambda}$) parity is even, the ($\ensuremath{\Sigma}, \ensuremath{\Lambda}$) mass ...

The charmonium mass spectrum is evaluated using the oscillator potential as responsible for long range confinement. Hyperfine splittings for the color singlet [Formula: see text] system are discussed using various approaches. The mass of [Formula: see text] and [Formula: see text] are also briefly touched upon.

Ultrasonic spectrum of adrenal masses
Urology, 1979Adrenal masses are amenable to ultrasonic examination. The ultrasonic characteristics of eight adrenal masses in 6 patients are described. In particular, an ultrasonic study of the natural history and progression of a large adrenal adenoma is reported.

Extended particles can possess an angular momentum as well as an intrinsic spin s. The energy can be expected to be a function of l(l + 1) and of s(s + 1) and may assume the simple form E/C/sup 2/ = aSTAl(l + 1) + s(s + l)!m/ sub e/The lightest meson is the mu meson with mass m == 207 m/sub e/.

Mass spectrum of tetrabutyltin
Bulletin of the Academy of Sciences of the USSR Division of Chemical Science, 19681. The mass spectrum of tetrabutyltin was taken on the MI-1305 and MI-1311 instruments, and a substantiation was given for the dependence of the ratio H4−xSnBux+/SnBux+ upon the number of butyl groups in the ion. The processes of decomposition of metastable ions were discussed. 2.

Discrete cluster mass spectrum
Il Nuovo Cimento A, 1978The discrete cluster mass spectrum suggested by cosmicray data is discussed within the context of a multistep cluster sequentialdecay model. It is shown that such a picture is compatible with the data on dispersion, provided the mass spectrum is not bounded from above as the energy increases.

Simple Mass Spectrum Linearizer
Review of Scientific Instruments, 1969An inexpensive modification of a commercial mass spectrometer is described which permits linear display of ion intensity vs m/e on an X-Y recorder. Its evaluation shows that the major limitations arise from recorder specifications. For magnetically scanning instruments, mass assignments can be made within ±0.006% utilizing the maximum zero offset of 85%

Organic Mass Spectrometry, 1974
AbstractThe mass spectrum of nitromethane points to rupture of the CH3NO2 bond as the dominant primary reaction, as also observed in pyrolysis, photolysis and radiolysis. Isomerization of the molecular ion to the nitrite configuration seems to contribute little in the mass spectrum of nitromethane, in contrast to those of nitrobenzene and other ...
