THE DEVELOPMENT OF SURFACE SEEDING

Grass and Forage Science, 1960
The principles of surface seeding as they apply to conditions in the north of Scotland are described and are illustrated by results from trials. The types of land and vegetation most suited to exploitation by surface seeding are indicated, and the need to consider the improvement of rough grazings in relation to a farm as a whole is stressed.Ploughing ...

Surface modifications for the development of piezoimmunosensors

Biosensors and Bioelectronics, 1998
Four different techniques for the immobilisation of proteins onto the gold electrode of a piezoelectric quartz crystal were investigated. The examined techniques were adsorption, avidin-biotin binding and two different types of covalent binding on self-assembled monolayers (SAM), dithiobis(succinimidylpropionate) (DSP) and a dextran modified thiol ...

Development of the optical surfaces of the kitten eye

Vision Research, 1978
Abstract In the intact post-natal kitten eye, an extensive vascular network severely limits optical quality. We have used scanning electron microscopy to find the locations of this network, to examine all optical surfaces of the eye, and to trace changes with age.

The characteristic development of trapped surfaces

Journal of Mathematical Physics, 1973
Conditions are found that are sufficient to insure the development of trapped surfaces in space-times whose metrics satisfy the Einstein field equations in vacuum or in the presence of a massless scalar field. These conditions involve a topological requirement that a certain two-surface be compact and inequalities that must be satisfied by certain ...

The development of the gadolinium surface state

Vacuum, 2004
Abstract The critical coverage for formation of the a 1 (d 3 z 2 – r 2 and s) symmetry gadolinium surface state appears to be in region of one monolayer for gadolinium on W(1 1 2) and is evident from a change in the density of states in the region near the Fermi level and a change in the band symmetry.

The Development of a Surface Arthroplasty for the Elbow

Clinical Orthopaedics and Related Research, 1986
Complex kinematics, anatomical features, and load distribution have contributed to the poor function of constrained and semiconstrained cemented arthroplasties of the elbow. Resurfacing by porous-coated components has the potential, by reproduction of normal joint geometry and restoration of ligament balance, to re-create relatively normal kinematics ...

The Research of the Development of Architectural Surface

Applied Mechanics and Materials, 2012
Architectural surface has changed very much compared with the traditional one in the past, because there are many opportunities for architects to experiment with space and form to express themselves today. What are the characteristics of traditional and modern architectural surface, why the characteristics keep changing all the time and how they are ...

The Genus of a Developable Surface

Mathematical Proceedings of the Cambridge Philosophical Society, 1935
Cayley's remark that the formula by which the genus of a surface, according to Clebsch's definition, may presumably be computed leads to a negative number in the case of a cone, or a developable surface, or a ruled surface in general, has great importance in the history of the theory.

Surface Aspects of the Developing Human Organ of Corti

Acta Oto-Laryngologica, 1987
Thirteen cochleas from human fetuses ranging in age from week 9 to week 22 were observed by scanning electron microscopy. The classical 'base-to-apex' and 'internal-to-external' gradients of maturation were confirmed by surface observations of the developing organ of Corti. The tectorial membrane begins to be secreted around week 9, i.e. 2 weeks before

Construction strategies and the development trend of antibacterial surfaces

Biointerphases, 2022
The construction of antibacterial surfaces is an efficient way to respond to the problem of microbial contamination. In this review, we first describe the formation process and characteristics of microbial contamination and the current research status of antibacterial surfaces.
