    Notes: Summary To define the kinetics of chylomicron apolipoprotein-B catabolism in diabetic subjects with lipaemia, autologous chylomicrons (Sf 400) harvested from plasma following an oral fat load were radioiodinated and re-injected. The radioactivity in the tetramethylurea-insoluble, non-lipid Sf〉400 lipoprotein fraction was followed in serial samples over 60–72h on a fat-free, isocaloric diet in: (1) five normal subjects; (2) four hypertriglyceridaemic, non-diabetic subjects; and (3) five diabetic patients (one subject, No. 3, was studied twice). The plasma apolipoprotein-B decay curve for the Sf 400 fraction disclosed biphasic disappearance: a rapid first phase (residence time 0.8–1.9 h) accounting for the large majority of removal (60%–95%) and a slower second phase (residence time 3.6–47.6 h), accounting for the remainder. Total chylomicron apolipoprotein-B residence times were similar in normolipidaemic (1.8–7.3 h) and hypertriglyceridaemic (2.3–10.3 h) non-diabetic subjects and the mildly hypertriglyceridaemic diabetic patients (5.6 and 5.8 h). In the untreated lipaemic diabetic subjects (Nos. 1 and 2), only a single, much slower phase was observed (total chylomicron apolipoprotein-B residence time 38.5–58 h). Adipose tissue biopsy in one of these subjects (No. 1) disclosed profoundly low lipoprotein lipase activity. The lipaemic diabetic subject (No. 3) studied early during treatment showed an intermediate pattern. These studies suggest a key role for insulin-dependent, lipoprotein lipase-mediated triglyceride hydrolysis in the removal of chylomicrons from plasma.

    Description / Table of Contents: Zusammenfassung Unter den Bedingungen der ariden Zone sind die mit der US-Verdunstungswanne gemessenen Verdunstungswerte viel größer als die nach der Methode von Penman berechnete potentielle Verdunstung. Zur besseren Angleichung an die beobachteten Verdunstungswerte wird eine neue Gleichung [Gl. (4)] abgeleitet, die die gleichen Terme wie Penmans Formel enthält, nämlich einen aerodynamischen Term und einen Energiebilanzterm. Der multiple Korrelationskoeffizient beträgt 0,9823. Es wurde festgestellt, daß in Gl. (4) die Gewichte von aerodynamischen und Energiebilanzterm im Verhältnis 0,61 zu 1,13 stehen, während sie in Penmans Gleichung sich wie 1 zu 4 verhalten. Daraus ergibt sich, daß in Penmans Formel der aerodynamische Term für die aride Zone unterbewertet ist.
    Notes: Summary It is found that under arid zone conditions, the evaporation by U.S.A. open pan evaporimeter is much higher than the potential evaporation obtained by Pennan's method. In order to represent the observed values of evaporation better, a new prediction equation [Eq. (4)] was obtained in terms of the same variables as in Penman's equation viz. aerodynamic term and energy balance term. The multiple correlation coefficient is 0.9823. It is found from the equation that the weightages for aerodynamic and energy balance terms are 0.61 and 1.13, while as per Penman's equation, the weightages for these terms are 1 and 4 respectively thereby showing that under estimation by Perman's method is due to low weightage given to the aerodynamic term which, under arid zone conditions, is not only numerically higher but also is more important in determining evaporation.

    Description / Table of Contents: Zusammenfassung Es werden Wochenmittelwerte des Wärmeflusses in sandigem bis lehmigem Sandboden in Jodhpur in Indien für die Jahre 1965 und 1966 berechnet. Im Durchschnitt ergibt sich für die ersten 22 Wochen von Januar bis Mai ein Wärmefluß von +25 cal/cm2 pro Woche. Von der 26. Woche, in der gewöhnlich der Südwest-Monsun in Jodhpur einsetzt, bis zur 37. Woche, auf die normalerweise das Ende des Monsuns fällt, treten große Schwankungen des Wärmeflusses im Boden auf. Die Werte variierten z. B. 1966 von +84 bis −116 cal/cm2 pro Woche. In Wochen mit Regenfällen weist der Wärmefluß große negative Werte, in dazwischenliegenden Trockenperioden aber große positive Werte auf. Dies mag zum Teil auf den Wärmetransport durch die Wasserbewegung zurückzuführen sein. In der Periode von der 37. Woche bis zum Jahresende nimmt die Wärmespeicherung mit nur sehr geringen Schwankungen kontinuierlich ab.
    Notes: Summary Weekly mean soil heat fluxes were worked out for 1965 and 1966 in respect of sandy to loamy sand soil of Jodhpur, India. On the average mean soil heat flux of +25 cal/sqcm/week occurs during 1st to 22nd standard week (January to May). From 26th week, which is the normal time of on-set of south west monsoon over Jodhpur to 37th week which is the normal period of its withdrawal there are large oscillations in the soil heat flux values. For instance values varied from +84 to −116 cal/sqcm/week during 1966. The weeks of rainfall have large negative fluxes while intervening dry periods have large positive fluxes. These may be partly due to transfer of heat with mass movement of water. The period from 37th week to end of the year is one of continuous decrease of heat storage with least fluctuations.
