A Foraminiferal Biostratigraphy of the Lower Senonian
(University of Plymouth, 1978)The necessity for a micropalaeontological examination of the lower Senonian chalk of southern England was established during the site investigation of the Thames Barrier, which Is founded on chalk of the Micraster ... -
THE IMMUNE RESPONSE OF THE DOGFISH SCYLIORHINUS CANICULA L.
(University of Plymouth, 1978)A number of aspects of the humoral and cellular immune responses of the common dogfish Scyliorhinus canicula L. were examined in order to define the immunological status of the animal in relation to its phylogenetic ... -
STUDIES ON THE DISTRIBUTION AND PHYSIOLOGY OF LEAD IN PLANTS
(University of Plymouth, 1978)The studies reported herein cover two main areas of research. The distribution of lead through the plant has been monitored using histochemical and quantitative techniques, and physiological responses of the plant to lead ... -
Cenomanian Ostracoda from Southern England: their Taxonomy, Stratigraphy and Palaeoecology
(University of Plymouth, 1978)Eight sections of Cenomanian Chalk from Southern England have been examined for their Ostracoda. A total of 111 species and 3 sub-species have been found and these fall into 47 genera. 38 of these species have been ... -
PROPERTY-MICROSTRUCTURAL RELATIONSHIPS IN GFRP
(University of Plymouth, 1978)This work consists of an investigation into the microstructure and mechanical behaviour of glass fibre reinforced polyester resin beams. The volume fraction occupied by glass fibres was 20-30%, which is that typically ... -
AN INVESTIGATION OF THE EFFECTS OF FATHER ABSENCE ON CHILDREN AGED BETWEEN FIVE AND ELEVEN YEARS

DIMENSIONAL RESPONDING IN CHILDREN AND ADULTS AS A FUNCTION OF STIMULUS AND RESPONSE VARIABLES
(University of Plymouth, 1978)Restricted classification and similarity rating tasks employing the dimensions of line length and density were used to investigate several issues. One of these was developmental differences in the overall separability of ... -
STRUCTURE - ACTIVITY RELATIONSHIPS IN SOME HERBICIDAL FLUORENE DERIVATIVES
(University of Plymouth, 1979)Synthetic plant-growth regulators derived from fluorene-9-carboxylic acid ('morphactins') are introduced and the literature on them is reviewed. Similar herbicidal activity has been found with 9,9-bishydroxymethylfluorene, a ... -
PEDAGOGIC STYLES IN PHYSICS TEACHING: AN ATTITUDE SCALING AND REPERTORY GRID STUDY
(University of Plymouth, 1979)The need for a greater understanding of the teaching-learning process in higher education is clearly evident from the rapid increase in research activity in this area over the last decade. Economic and political pressure ... -
INVESTIGATION OF PARAMETERS AFFECTING THE OPERATING CHARACTERISTICS OF TOGGLE-SWITCHES WITH SILVER-CADMIUM-OXIDE CONTACTS
(University of Plymouth, 1979)Experimental and theoretical studies are made of small snap-action switches designed for use in thermostatic controls operating on a.c. at 240 volts r.m.s., 50Hz. The performance of the silver cadmium oxide contacts (Ag. ... -
OPERATION OF V.L.C.C.'S IN HEAVY WEATHER
(University of Plymouth, 1979)A short review is presented of available instrumentation systems designed to assist the operation of ships in heavy weather by warning against dangerous wave loads. Some systems also give guidance to the master by predicting ... -
