    Notes: Small-angle X-ray scattering from oriented mats and random suspensions of polyethylene single crystals has been studied. A modification of the Guinier equation for platelets was derived to accommodate the two-phase nature of polymer lamellae. This modification also permitted the modelling of various degrees of interaction between lamellae and suspending media. Dried crystal mats show an increase in fold period on contact with potential solvents. Crystals which have never been dried show no evidence of penetration of the fold surface by the same liquids. Apparently the drying process causes a reorganization of the surface of the lamellae. Since the fold surfaces of crystals in suspension are unaffected by the liquids used, it is reasonable to assume a `tight' fold surface model. Crystallinities calculated with this model are in excellent agreement with recent differential scanning calorimetric data on crystals kept in suspension.

    Description / Table of Contents: Übersicht Es werden Biegeschwingungen einer rotierenden, gekrümmten, balkenförmigen Schaufel von kreisförmiger Vorkrümmung unter Verwendung des Galerkin-Verfahrens untersucht. Die Verschiebungsansätze werden durch Legendre-Polynome ausgedrückt. Trägheitskräfte in Längsrichtung und Corrioliseffekte sind vernachlässigt worden. Für unterschiedliche Drehzahlen sind die Schaufeleigenfrequenzen in Abhängigkeit von Rotordurchmesser, Schaufelquerschnittsorientierung und Vorkrümmung berechnet und in Kurvenform dargestellt worden. Die Vorkrümmung hat nur geringen Einfluß auf das Frequenzspektrum der stehenden Schaufel. Bei der rotierenden Schaufel sinken die Schaufeleigenfrequenzen mit zunehmender Vorkrümmung, und die Abnahme gegenüber den Eigenfrequenzen des geraden Balkens wächst mit der Drehzahl. Hingegen hat die Orientierung des Schaufelquerschnittes nur auf die Grundfrequenzen merklichen Einfluß.
    Notes: Summary Bending vibrations of a rotating curved cantilever beam with, centroidal axis represented by a circular arc have been investigated by using Galerkin's method. Legendre polynomials are used to represent the shape functions. Longitudinal inertia and Coriolis effects are neglected in the analysis. At various rotating speeds, frequencies accounting for hub size, beam cross-section orientation and curvature have been computed and presented by curves. The beam curvature has only little effect on the frequency for nonrotating beams. For rotating beams the frequency generally decreases as the curvature increases, and the reduction from the straight beam frequency increases as the rotating speed increases. The effect of the beam cross-section orientation is significant only for the fundamental frequencies.

    Notes: Summary The fate of lectin labeled internalized plasma membrane in the ascites tumor form of the Chang rat hepatoma growing under in vivo and in vitro conditions was investigated cytochemically. Ascites cells were incubated in Concanavalin A (Con A) and horseradish peroxidase (PO), either with or without prior glutaraldehyde fixation and subsequently treated with 3′,3-diaminobenzidine. In cells fixed before Con-A-PO labeling the reaction product was localized as a continuous and even layer upon the external surface of the plasma membrane. If unfixed cells were treated with Con A, coupled with PO at 4°C and reinbated in phosphate buffered saline at 37°C for varying periods of time, the Con-A-PO layer was of irregular thickness. In as little as 15 min of reincubation endocytotic vesicles containing PO positive material were closely associated with GERL components of the Golgi Apparatus. Localization of acid phosphatase (ACPase) within GERL vesicles, similar in size and location to those containing Con-A-PO reaction product, indicates that the Con-A-PO labeled vesicles may be a component of the Golgi apparatus in hepatoma cells.

    Notes: Abstract A theory is developed to describe the heating of a planary skin-fat-muscle tissue combination by electromagnetic wave diathermy. Both shortwaves and microwaves are treated. All mechanisms of heat dissipation are taken into account. The effects of wave frequency, power input, ambient conditions, vasodilation and core boundary conditions on the thermal distributions in the tissues are determined. The theoretical results agree well within vivo temperatures recorded in human thighs. It is concluded that (a) microwaves at 2450 MHz yield peak temperatures in the skin layer, a superficial heating agent, (b) 900MHz radiation has a pronounced temperature rise and the highest peak value in the musculature, most attractive for deep issue heating, and (c) shortwaves at 27·12 MHz produce a wide plateau of elevated temperature in the muscle layer using a high power intensity.

    Notes: Abstract In the context of a broad definition of agrochemistry, any chemicals produced by agricultural activities may be included here. Interactions between agrochemicals and their environment are the central theme of this paper. This is elucidated in terms of the alterations of radiant energy transfer, heat budget, and water balance at the interface of air and ground. The disrupted states of the atmosphere are presented by climatic elements, weather phenomena, and edaphic conditions. Realizing that the whole earth-atmosphere system tends to approach a state of minimal free energy, a step by step combination of the physical and/or chemical process is given. Emphasis is on the visible and infrared radiant energy transfer, attenuation, nucleation, sorption-condensation, fermentation, combustion, and radiative heating processes. Although this paper stresses the micro-mesoscale weather phenomena and short term effects, agrochemical impact on long-term and global weather and climate should not be ignored. Due to lack of study in this subject area, recommendations for future research stress both experimental and mathematical modeling techniques.
