A non-therapeutic method of improving growth performance of a weaning mammal comprises a step of administering to the weaning mammal or a maternal mammal an effective amount of beta-glucan and casein hydrolysate, wherein the weight ratio of beta-glucan to casein hydrolysate is 1:2 to 2:1. A dietary supplement suitable for oral administration to a mammal comprising beta-glucan and casein hydrolysate is also provided, wherein the weight ratio of beta-glucan to casein hydrolysate is 1:2 to 2:1.

Embodiments of the present invention produce and define a relationship between local voltage and power measurements at a node of an electrical network and system conditions on a remote branch of the network. These local measurements are used to determine an optimal voltage set point at the node that, if realised by a reactive power resource, would affect the flow of reactive power or line current at one or more particular remote branches of the power system in a manner captured by the derived relationship. The change in reactive power required to obtain this voltage set point is also calculated based on local measurements.

The present invention is concerned with a hollow fibre membrane for use in a Membrane Supported Biofilm Reactor (MSBR) or the like, the hollow fibre membrane comprising a substantially cylindrical sidewall defining an internal lumen from which gas can permeate through the sidewall, and characterised in that at least a part of an outer surface of the fibre membrane is engineered to define at least one biofilm retaining region which acts to retain a quantity of biofilm therein, in particular when the fibre membrane is subjected to a high sheer biofilm control event, such as experienced during a reactor cleaning cycle, for removing excess biofilm in order to prevent clogging of the reactor.

Adequate characterization of NPs (nanoparticles) is of paramount importance to develop well defined nanoformulations of therapeutic relevance. Determination of particle size and surface charge of NPs are indispensable for proper characterization of NPs. DLS (dynamic light scattering) and ZP (zeta potential) measurements have gained popularity as simple, easy and reproducible tools to ascertain particle size and surface charge. Unfortunately, on practical grounds plenty of challenges exist regarding these two techniques including inadequate understanding of the operating principles and dealing with critical issues like sample preparation and interpretation of the data. As both DLS and ZP have emerged from the realms of physical colloid chemistry - it is difficult for researchers engaged in nanomedicine research to master these two techniques. Additionally, there is little literature available in drug delivery research which offers a simple, concise account on these techniques. This review tries to address this issue while providing the fundamental principles of these techniques, summarizing the core mathematical principles and offering practical guidelines on tackling commonly encountered problems while running DLS and ZP measurements. Finally, the review tries to analyze the relevance of these two techniques from translatory perspective. © 2016 Elsevier B.V. All rights reserved.

Micromagnetics has been the method of choice to interpret experimental data in the area of microscopic magnetism for several decades. In this article, we show how progress has been made to extend this formalism to include thermal and quantum fluctuations in order to describe recent experimental developments in nanoscale magnetism. For experimental systems with constrained dimensions such as nanodots, atomic chains, nanowires, and thin films, topological defects such as solitons, vortices, skyrmions, and monopoles start to play an increasingly important role, all forming novel types of quasiparticles in patterned low-dimensional magnetic systems. We discuss in detail how soliton-antisoliton pairs of opposite chirality form non-uniform energy barriers against thermal fluctuations in nanowires or pillars. As a consequence of their low barrier energy compared to uniform reversal, they limit the thermal stability of perpendicular recording media. For sufficiently short samples, the non-uniform energy barrier continuously merges into the conventional uniform Néel-Brown barrier. Partial formation of chiral domain walls also determines the magnetic properties of granular nanostructured magnets and exchange spring systems. For a long time, the reconciliation between micromagnetics and quantum mechanics has remained an unresolved challenge. Here it is demonstrated how inclusion of Berry's phase in a micromagnetic action allows for a semiclassical quantization of spin systems, a method that is demonstrated by the simple example of an easy-plane spin. This powerful method allows for a description of quantum dynamics of solitons and breathers which in the latter case agrees with the anisotropic spin-XYZ-model. The domain wall or soliton chirality plays an important role as it is coupled to the wavevector of the quasiparticle dispersion. We show how this quantum soliton chirality is detected by polarized neutron scattering in one-dimensional quantum antiferromagnets. © 2012 Taylor & Francis.
