title: A Novel Implant Electrode Design Safe in the RF Field of MRI Scanners

authors: McCabe, Steven Owen

abstract: Patients with medical implants are often unable to receive magnetic resonance imaging (MRI) diagnostic treatment, because the conductive leads can concentrate the RF excitation field and generate dangerous heating of nervous tissue. We propose a simple, low-cost solution that minimizes RF heating through the addition of one or more mutually coupled filars to the lead without significant increase in lead diameter. Simulations and measurements at 128 MHz are presented to verify the effect in 3 T MRI machines.

title: An overview of nano-crystalline cellulose nanofibers and their applications in drug delivery

authors: Aljbour, ND

abstract: Made from a variety of natural sources, Nano Crystalline Cellulose (NCC) is a unique renewable nanomaterial with a wide range of applications due to its high stiffness and strength, low weight, biodegradability, and environmental benefits. Because of its special inherent qualities, NCC is one of the most renewable materials to be addressed by nanomaterials. The origins, manufacture, characteristics, and applications of nanomaterials, including NCC and nanofibers, have been extensively studied by a large number of researchers throughout the years. Strong chemical reactivity, crystallinity, strength and stiffness, biocompatibility, biodegradability, shape, and nanoscale dimensions are just a few of the remarkable properties that these nanomaterials have been shown to possess in countless investigations. These characteristics enable the application of these nanoparticles in a number of fields, including medicine. Among the most traditional and popular techniques. Electrospinning is one of the earliest and most popular techniques for producing nanofibers. This method works well and can be modified to produce continuous nanofibers. NCC-based nanofibers are novel materials in the biomaterials industry. Recent studies demonstrated that electrospun nanofibers could be efficiently loaded with a wide range of drugs, such as proteins, chemotherapeutic agents, antibiotics, and analgesics with anti-inflammatory qualities. One application of NCC and nanofibers in the medical field is drug delivery. This review highlights a number of issues related to NCC nanofibers and their use in drug delivery applications, beginning with discussing the various natural polymer types used in drug delivery applications, the physicochemical and biological properties of NCC, its various applications, its significance, and its preparation techniques.

title: Drawing on linguistic concepts to teach te reo Māori; Drawing on te reo Māori to teach linguistic concepts

authors: Wessels, Kanauhea Janion

subjects: linguistic pedagogy

abstract: In this paper, we explore the intersections in our teaching practice between the discipline of linguistics and te reo Māori. From the perspective of language teaching, in pedagogic materials for te reo Māori, we have observed that linguistic concepts are not typically highlighted (cf. Moorfield 2001, Jacobs 2012). From the perspective of teaching linguistics, te reo Māori is seldom employed to illustrate or assess linguistic concepts, although it commonly features in accounts of language revitalization. Content that does occur is limited (cf. Burridge & Stebbins, 2016). 
As a tertiary lecturer of the Māori language, I (Kanauhea) consider how, in my teaching practice, I draw on my technical knowledge of linguistics to enhance my explanations of language structures and their functions, where these are unfamiliar to language learners. As a tertiary linguistics lecturer, I (Julie) consider ways in which I draw on my beginner knowledge of te reo Māori to enhance my teaching of linguistic concepts, reflecting on materials I have developed to teach and assess students. 
We argue that students of te reo can benefit from linguistic understandings on their language learning journeys. Equally, as Aotearoa New Zealand's indigenous language, te reo Māori should have a strong presence in linguistic teaching materials, and our linguistics students should graduate with an indepth knowledge of te reo Māori structures.
