    Notes: Abstract The purpose of this study was to evaluate usefulness of right lateral position CT in determining invasion of gastric cancer into adjacent organs. We assessed whether position shift, a change in the relative location of a gastric tumor and adjacent organs between the supine position and right lateral position CT, was a useful sign for absence of invasion into perigastric organs. In 37 patients with advanced gastric cancer with doubtful invasion into adjacent organs by conventional CT after 500 ml water oral intake, additive right lateral CT was performed. Of 24 cases of lesions in the gastric body, 16 had a position shift and no invasion into adjacent organs at surgery (T3), and 8 had no position shift and invasion (T4). The accuracy was 100%. Six gastric cardial and 7 pyloric tumors showed no position shift, and 3 cardial and 2 pyloric tumors were proved to be noninvasive (T3). The accuracy of cardial and pyloric tumor was 50 and 71%. We concluded that position shift may be useful in the diagnosis of invasion of adjacent organs by gastric cancer, limited to in cases with gastric body cancer.

    Description / Table of Contents: Riassunto La dipendenza degli spettri di Raman di primo ordine dalla pressione idrostatica in cristalli di ZnSiP2 è stata misurata fino a 52k bar e il parametro di Grüneisen di ogni modo di Raman è stato ottenuto. I modi fononici osservati nel cristallo di ZnSiP2 possono essere classificati in cinque gruppi secondo il valore del parametro di Grüneisen del modo. La corrispondenza tra modi di Raman in ZnSiP2 e quelli nel suo analogo binario GaP è stata chiarita confrontando i parametri di Grüneisen nei due cristalli. Da tale corrispondenza sono stati chiariti complicati modi di vibrazione reticolare in ZnSiP2.
    Abstract: Резюме Измеряется зависимость от гидростатического давления вплоть до 52 кбар Рамановских спектров пектров первого порядка в кристаллах ZnSiP2. Для каждой Рамановской моды получен параметр Грюнайзена. Наблюденные фононные моды в кристалле ZnSiP2 могут быть классифицированы а пять групп, соответственно параметру Грюнайзена. Объясняется соответствие между Рамановскими модами в ZnSiP2 и Рамановскими модами в бинарном аналоге GaP, посредством сравнения параметров Грюнайзена в двух кристаллах. Это соответветствие проясняет сложные моды колебаний решетки в ZnSiP2.
    Notes: Summary The hydrostatic-pressure dependence of the first-order Raman spectra in the ZnSiP2 crystal has been measured up to 52 kbar and the Grüneisen parameter of each Raman mode was obtained. Phonon modes observed in the ZnSiP2 crystal can be classified into five groups according to the value of the Grüneisen mode parameter. The correspondence between Raman modes in ZnSiP2 and those in its binary analog GaP was elucidated by comparing Grüneisen parameters in the two crystals. From such a correspondence, complicated lattice vibration modes in ZnSiP2 were made clear.

    Description / Table of Contents: Riassunto Si sono fatte misurazioni degli spettri di fotoluminescenze e di eccitazione luminescenza di ZnSiP2 a 4.2 K e si sono ottenuti due risultati. Uno è l'osservazione di una nuova linea netta di emissione a 1.980 eV, dovuta all'eccitone legato associato col gap pseudodiretto. L'altro è l'osservazione di un'altra nuova serie di linee di assorbimento nello spettro di eccitazione di luminescenza di una linea di emissione a 1.984 eV, oltre a quelle riportate in precedenza. Questi risultati indicano che in ZnSiP2 si verificano transizioni radiative sia per gap indiretti che per gap pseudodiretti.
    Abstract: Резюме При 4.2 К проведены измерения спектров фотолюминесцендии и спектры возбуждения люминесценцией в ZnSiP2 и получено два результата. Один результат представляет наблюдение новой резкой линии излучения при 1.980 эВ. обусловленной связанным экситоном, ассоциированным с псевдопрямым интервалом. Второй результат предсталяет наблюдение новых линий поглошения в спектре возбуждения люминесценцией линии излучения при 1.984. эВ. Эти результаты указывают, что в ZnSiP2 радиационные переходы происходят при косвенных и псевдопрямых интервалах.
    Notes: Summary Measurements of photoluminescence and luminescence excitation spectra of ZnSiP2 have been performed at 4.2K and two results were obtained. One is the observation of a new sharp emission line at 1.980 eV, due to the bound exciton associated with the pseudodirect gap. The other is the observation of another new series of absorption lines in the luminescence excitation spectrum of an emission line, at 1.984 eV, in addition to those reported previously. These results indicate that in ZnSiP2 radiative transitions occur at both the indirect and the pseudodirect gaps.
