Polymd. and crosslinked unsatd. glycerides were used as emulsifying agents (3-5%) for soybean oil, giving ≤50% aq. emulsions. The d.p., mol. wt. distribution, viscosity, dielec. const., and refractive index of the emulsifier were correlated with the emulsion stability, with mol. wt. ∼40,000 giving the best results.

המאמר הנוכחי מניח כי רוב ההגדרות של המושג תעשייה בעלת "טכנולוגיה גבוהה" מבוססות על מאפיין מגדיר אחד בלבד. אנו טוענים כי הגדרה נאותה חייבת להתבסס על תפיסה רב-ממדית של מושג הטכנולוגיה, ומציגים גישה מתודולוגית לסיווג ענפי תעשייה "לטיפוסים טכנולוגיים" על סמך ההיבטים השונים של הטכנולוגיה שהם מייצגים. בהסתמך על מתודולוגיה זו, אנו מגישים בדיקה אמפירית מבוסס על ענפי-משנה של התעשייה הישראלית (ברמת שלוש ספרות בסווג האחיד של ענפי התעשייה). השימוש בניתוח אשכולות ובניתוח שונות מאפשר לנו להראות כי לפרופילים הטכנולוגיים שהוגדרו יש מאפיינים
In this case the permanent successor was so radiographically indistinct due to the inflammatory process that this three-year-old Arab boy might have been classified as having congenital absence of the mandibular left first premolar, if the mass had not been sent for histological section. The clinical implications are identical.

“Variation Of Population Release Kinetics In Polydisperse Multiparticulate Systems (Microcapsules, Microspheres, Droplets, Cells) With Heterogeneity Of One, Two Or Three Parameters In The Population Of Individuals.”. The Journal Of Pharmacy And Pharmacology, 40, 2, Pp. 93–96. doi:10.1111/j.2042-7158.1988.tb05188.x.
תקציר Release kinetics of active substances from ensembles of microparticles such as microcapsules, cells, droplets and liposomes constituted of individual entities releasing their contents at constant rates may follow zero order, first order, sigmoid or biphasic equations. The release equation observed depends upon the statistical distribution of release-determining parameters among the population. Typical cases are presented in terms of the distribution of two parameters, payload (m infinity) and time for complete payload release (t infinity) which also define the release rate constant (k). Heterogeneity of the two parameters generally leads to first order ensemble behaviour, whereas heterogeneity of one parameter only may lead to different ensemble release equations, viz. zero order (m infinity heterogeneous) or first order (t infinity heterogeneous). Biphasic distribution can lead to an apparent 'burst' effect, with apparent change of kinetics. The presence of a third heterogeneous parameter, lag time, yields a sigmoid ensemble release curve. These conclusions are demonstrated by simulations or experimentally, and are also valid for linearized curves of microparticles following matrix kinetics.
