Technological options that respond to demands and market opportunities with focus on crops and livestock

Technology development is a core area of agricultural research, and the increasing global focus on client-demand and market oppourtunities is intended to increase its releance and effectiveness. This theme focuses on the achievements of and lessons learnt from technological optipns developed for crop and livestock systems including breeding, management practices and processing and appropriate technolgies, knowledge, information and methods that enhance productivity, value addition and the competitiveness of the products in both national and international markets. A number of research providers as well as public sector bodies such as national agricultural systems and universities, non-governmental organisations which have links to broad farmer networks have become increasingly involved in research activities. Consequently, agricultural researchers have and are continually developing a broad range of technological options to secure the production of safe food and non food cash crops and to achieve the most efficient and ecologically sound use of natural resources; soil, water and energy. It is however apparent that farmers prefer packages of information not just pest management strategies alone but a total package including other aspects such as soil and weed management options

Profession Based Hierarchies as Barriers for Genuine Learning Processes

Under embargo until: 2021-06-26This chapter describes how profession based hierarchies (stratified social orders between professions) may appear in a teaching context of interprofessionality involving a variety of health professions presenting challenges to learning and offers suggestions on how these challenges can be overcome.acceptedVersio

A Mathematical Model for the Dynamics and Synchronization of Cows

We formulate a mathematical model for daily activities of a cow (eating, lying down, and standing) in terms of a piecewise affine dynamical system. We analyze the properties of this bovine dynamical system representing the single animal and develop an exact integrative form as a discrete-time mapping. We then couple multiple cow "oscillators" together to study synchrony and cooperation in cattle herds. We comment on the relevant biology and discuss extensions of our model. With this abstract approach, we not only investigate equations with interesting dynamics but also develop interesting biological predictions. In particular, our model illustrates that it is possible for cows to synchronize \emph{less} when the coupling is increased.Comment: to appear in Physica

Rare variants with large effects provide functional insights into the pathology of migraine subtypes, with and without aura

Publisher Copyright: © 2023, The Author(s).Migraine is a complex neurovascular disease with a range of severity and symptoms, yet mostly studied as one phenotype in genome-wide association studies (GWAS). Here we combine large GWAS datasets from six European populations to study the main migraine subtypes, migraine with aura (MA) and migraine without aura (MO). We identified four new MA-associated variants (in PRRT2, PALMD, ABO and LRRK2) and classified 13 MO-associated variants. Rare variants with large effects highlight three genes. A rare frameshift variant in brain-expressed PRRT2 confers large risk of MA and epilepsy, but not MO. A burden test of rare loss-of-function variants in SCN11A, encoding a neuron-expressed sodium channel with a key role in pain sensation, shows strong protection against migraine. Finally, a rare variant with cis-regulatory effects on KCNK5 confers large protection against migraine and brain aneurysms. Our findings offer new insights with therapeutic potential into the complex biology of migraine and its subtypes.Peer reviewe
