SSNMR confirms silicate ion substitution in the apatitic structure of 0.8wt% Si hydroxyapatite2023 •
This paper details investigation of the structural location of the silicon present in ‘silicate-substituted’ apatite (SA). To date, it has been hypothesised that the silicon is present either in the form of silicate groups site-specifically substituted in the hydroxyapatite lattice for phosphate groups, or that there may be an amorphous silicon-rich phase in the vicinity of the grain boundaries. Solid state nuclear magnetic resonance (SSNMR) spectroscopy was undertaken to view the elemental interactions using phosphorus (31P) and silicon (29Si) probes in order to confirm or refute the presence of silicate groups in relation to phosphate groups in the bulk material structure. The analysis was performed on stoichiometric hydroxyapatite (HA) and silicate-substituted hydroxyapatite (SA) with a nominal silicon content of 0.8wt% silicon, in as precipitated, calcined (700°C) and sintered (1250 and 1300°C, respectively) powder forms. XRD confirmed all forms of powder were phase pure, FTIR confirmed both hydroxyl and phosphate group functionality in all forms of powder in both HA and SA, while silicate group functionality was only observed in all forms of SA powders. SSNMR using 31P and 29Si coupled probes demonstrated that as the crystallinity of the powders increased from the precipitate to the sintered form, the signal associated with the presence of a silicate group in the phosphate environment developed as the crystal structure becomes more ordered. These results support the hypothesis that in SA containing 0.8wt% silicon, silicate groups are site-specifically substituted in the hydroxyapatite lattice for phosphate groups. This observation may be key to understanding the mechanisms by which the introduction of 0.8wt% silicon enhances bone regeneration in apatitic bone graft substitute materials.

In this review, we discuss animal welfare as a complex and contested issue facing society and outline why collaborative, multi-stakeholder approaches are critical for effective policy development. Using the lens of “wicked problems” and drawing upon governance literature on policy networks, we identify important factors for working with the inherent complexity of animal welfare through the inclusion of various stakeholder perspectives. We present two case studies that illustrate policy network approaches to animal welfare and highlight the value of fostering collaboration among various stakeholder groups from the industry, community, research, and government sectors. We suggest that the influence of stakeholder networks will likely increase in coming years as newer forms of participatory governance become common. By understanding how collaborative stakeholder networks establish participatory governance, productive communication, and collective priorities, leaders in the field of ani...

Managerial oversight rather than inadequate finance has been ascribed as the necessitating fundamental to business failure in less-developed countries. Finance plays a crucial role in the establishment, growth and sustainability of business. However, it is delicate; its inadequacy or excess is as dangerous asineffective management. This paper examines the importance of finance function, the imperativeness of financial strategies and the special role of finance manager in business sustainability. In addition, a reflection is made of the financial management practicesof businesses in African countries, and recommendations made for changes required for their sustainability.

Impact of Citrus Pulp or Inulin on Intestinal Microbiota and Metabolites, Barrier, and Immune Function of Weaned Piglets2021 •
We investigated the use of citrus pulp (CP) as a novel prebiotic capable of exerting microbiota and immunomodulating capacities to alleviate weaning stress. Inulin (IN), a well-known prebiotic, was used for comparison. Hundred and 28 male weaned piglets of 21 days old were assigned to 32 pens of 4 piglets each. Piglets were assigned to one of the four treatments, i.e., control, IN supplemented at 0.2% (IN0.2%), and CP supplemented either at 0.2% (CP0.2%) or at 2% (CP2%). On d10–11 and d31–32 post-weaning, one pig per pen was euthanized for intestinal sampling to evaluate the growth performance, chyme characteristics, small intestinal morphology, colonic inflammatory response and barrier integrity, metabolite profiles [gas chromatography-mass spectrometry (GC-MS), and liquid chromatography-mass spectrometry (LC-MS)], and microbial populations. The IN treatment and the two CP treatments induced higher small intestinal villus height to crypt depth ratios in comparison with the control ...
