Development of Soil on the Lunar Surface
SEPM Journal of Sedimentary Research, 1972Discussion of the dynamic processes involved in the evolution of the lunar soil. Size, shape, and modal analyses of soil returned by Apollo 11, 12, 14, and 15, and Luna 16 indicate that the two most important dynamic processes resulting from meteorite impact are vitrification and comminution of the detrital material.

Development of surface immunoglobulins in the chicken.
Immunology, 1975B-cell maturation in the chicken has been evaluated by the appearance of membrane immunoglobulins on cells in the spleen, the thymus, the bursa and the bone marrow during enbryonic development and shortly after hatching. The majority of the bursa cells acquire demonstrable membrane immunoglobulin between days 16 and 18 of incubational age and show ...

The development of standards for surface analysis
Surface and Interface Analysis, 1988Abstract As the use of surface analysis increases, the need for standards (reference procedures, reference data, and reference materials) becomes more urgent. This article describes recent activities and current plans of three organizations that are active in developing standards for surface analysis: Committee E‐42 on Surface ...

The development of the fundamental concepts of surface thermodynamics
Colloid Journal, 2012Author’s results concerning the most fundamental problems of the thermodynamics of surface phenomena are reviewed. The generalized Laplace-Young-Kelvin equation, phase rules, and Gibbs adsorption equations are presented. Analogs of Konovalov’s laws are describes as applied to surface phenomena.

Exploiting mucosal surfaces for the development of mucosal vaccines
Vaccine, 2011Mucosal immunity covers a variety of mucosal surfaces susceptible to different pathogens. This review highlights the diversity of mucosal tissues and the unique microenvironments in which an immune response is generated. It argues that tissue-specific factors present throughout mucosal tissues and lymph nodes determine the differentiation into IgA ...

Development of Procoagulant Binding Sites on the Platelet Surface
1985Activation of coagulation factor X by a complex of factors IXa-VIIIa and prothrombin by a complex of factor Xa.Va is markedly enhanced in the presence of a negatively-charged phospholipid surface. A suitable phospholipid surface is provided by a platelet lysate but not by a suspension of intact platelets, due to the internal localization of ...

On developable ruled surfaces of the principle-direction curve
2017This study is devoted to improve the theory of the developable ruled surfaces in terms of principal-direction curves of any spatial curve in three-dimensional Euclidean space. We obtain the new representation for developable surfaces by slant helices and the useful elements such as pitch, angle of pitch and dral with the help of a new frame {N, C, W ...
