Zonal rotor study of the subcellular distribution of acyl-CoA synthetases, carnitine acyl transferases and phosphatidate phosphatase in the guinea-pig small intestine.
(European Journal of Cell Biology, 1979)
Homogenates made from the mucosa of the guinea pig small intestine were fractionated in a zonal rotor by rate and isopycnic centrifugation in sucrose gradients. Density perturbation of endoplasmic reticulum vesicles was ...
Zonal rotor analysis of the subcellular localization of B-glycero-phosphate dehydrogenase, 1-naphthyl palmitate and 2-napthyl laurate hydrolases in the mucosa of the guinea-pig small intestine.
(Histochemistry Journal, 1976)
Whole homogenate of guinea-pig small intestine mucosa was analysed by centrifugation in a zonal rotor. The results indicate that FAD-linked a-glycerophosphate dehydrogenase is localized in the mitochondria and that ...
Intestinal peroxisomes of goldfish (Carrassius auratus) - examination for hydrolase, dehydrogenase and carnitine acetyltransferase activities.
(Comparative Biochemistry and Physiology, 1979)
1. Rate sedimentation and isopycnic centrifugation were used to analyse the subcellular sites of enzymes in homogenates of goldfish intestinal mucosa. 2. The results allowed the following allocations to be made: carnitine ...
Subcellular localization of monoglyceride acyltransferase, xanthine oxidation, NADP: isocitrate dehydrogenase and alkaline phosphatase in the mucosa of the guinea-pig small intestine.
(Comparative Biochemistry and Physiology, 1980)
1. Rate dependent and isopycnic banding in a zonal rotor were used to analyse the subcellular sites of enzymes in homogenates of guinea-pig small intestinal mucosa. 2, The results demonstrate the following localizations: ...
Chromosomes of Leiobunum japonicum japonicum and Leiobunum paessleri (Arachnida, Opiliones).

Social Interaction in Self-paced Distance Education.
(Open Praxis, 2015)
In this paper we present a case study of a self-paced university course that was originally designed to support independent, self-paced study at distance. We developed a social media intervention, in design-based research ...
On the Design of Social Media for Learning
(social sciences, 2014-08-08)
This paper presents two conceptual models that we have developed for understanding ways that social media can support learning. One model relates to the “social” aspect of social media, describing the different ways that ...
Agoraphobia and the modern learner.
(Journal of Interactive Media in Education, 2014-03)
Read/write social technologies enable rich pedagogies that centre on sharing and constructing content but have two notable weaknesses. Firstly, beyond the safe, nurturing environment of closed groups, students participating ...
The Distant Crowd: Transactional Distance And New Social Media Literacies.
(International Journal of Learning and Media, 2014)
Sociality is not just a cultural phenomenon but is embedded in our genes as eusocial creatures (E. O.Wilson 2012). Learning is an innately social activity, and the processes of teaching, the passing of knowledge from one ...
P-learning’s unwelcome legacy
Formal teaching of adults has evolved in a context de ned, initially, by the constraints of physical boundaries. Classroom walls directly entail timetables, norms and rules of behaviour, social segregation into organized ...
