    Notes: Summary Production values (PVs), defined as the weight of the end product/weight of the substrate required for carbon skeletons and energy production, were calculated for plant fatty acids. The PVs varied from 0.361 to 0.300 with linolenic acid having the lowest value. In general, the PVs of unsaturated fatty acids were lower than those of saturated fatty acids of similar chain lengths. Using this basic information, PVs of (A) oils from different oilseed crops, based on their standard fatty acid composition and (B) seed biomass with specified oil content and fatty acid composition were calculated. 1/PV gives the glucose required for the biosynthesis of 1 g end product and thus an estimate of the photosynthate requirement for the desired breeding goal can be estimated. Such calculations show that increasing oil percentage in seeds has a maximum energy cost when the increase in oil is associated with a decrease in the amount of carbohydrates where there is no change in protein concentration. Reduction of erucic acid content in the rapeseed oil did not alter its PV. It is inferred that there are no serious bioenergetic constraints in altering the fatty acid composition.

    Notes: Summary Total nitrogen, amino nitrogen, glutamic acid dehydrogenase (GDH) activity and incorporation of 3H-uridine and 14C-amino acids into RNA and proteins, respectively, were compared in the developing grains of three high-protein stocks (IR-480-5-9, GMPR-51 and Erythroceros) and a high-yielding, medium-protein cultivar IR-8. The above parameters were also independently studied in the developing grains of IR-8 grown at 0, 60 and 120 kgN/ha. In addition, mobilization of nitrogen from flag leaf during kernel development was compared in a separate experiment. Higher protein concentration, both in high-protein stocks and in IR-8 grown at 120 kgN/ha, was associated with increased levels of: soluble amino nitrogen, GDH activity, 3H-uridine and 14C-amino acid incorporation. Significant variation was found among the high protein stocks in mobilization of nitrogen from flag leaf.

    Notes: Abstract Seed globulins ofCajanus cajan a widely cultivated legume were purified and characterised. About 78% of the seed proteins were salt soluble, out of which 61% were globulins which were further separated into three fractions. The ∞ fraction was insoluble at pH 4.7 and consisted of two subfractions. Fraction β and γ were soluble at pH 4.7. All the fractions were characterised as glycoproteins by cesium chloride centrifugation. The proteins consisted of subunits which were not held together by covalent disulphide linkages. Amino acid analysis of the different globulin fractions showed that the γ fraction was comparatively rich in sulphur amino acids.

    Description / Table of Contents: Zusammenfassung In dieser Arbeit wird eine Methode zur näherungsweisen Berechnung der stationären, reibungsfreien, schallnahen Strömung um Profile unter Berücksichtigung von Stoßwellen angegeben. Unter Verwendung einer der vonHosokawa [11] angewendeten ähnlichen Vorgangsweise wird die vonNiyogi undMitra [9] ermittelte stoßwellenfrei schallnahe Lösung auf den Fall mit Stoßwellen erweitert. Die überkritischen Strömungen längs eines Parabelbogen- und eines NACA-Profiles werden berechnet und mit theoretischen Ergebnissen vonOswatitsch undZierep, mit solchen nach dem Differenzenverfahren vonMurman undCole [13] ermittelten und mit experimentellen Ergebnissen verglichen. Die Übereinstimmung ist zufriedenstellend.
    Notes: Summary The present work gives a procedure for computing approximately steady inviscid transonic profile flow with shock. Using an analysis similar to that adopted byHosokawa in [11] it extends the shock-free transonic solution ofNiyogi andMitra [9] to the case of flow with shock. Supercritical flow past parabolic are profiles and a NACA profile are computed and compared with theoretical results ofOswatitsch andZierep and finite difference solution ofMurman andCole [13] and with experimental results. The agreements are satisfactory.
