title: Cross-Needle analog meter to monitor charge time for Lithium-Ion single cell

authors: Mohri, Hiroshi

subjects: Cross-Needle Meter

abstract: The Cross-Needle panel meter is an analog Standing wave ratio meter with a modified panel. It consists of two meters which are mirrored horizontally and 38mm apart. One needle indicates the forward travelling wave on a trans-mission line, while the other needle indicates reverse travelling wave. A third scale, occupying the area swept by both needles, shows Standing Wave Ratio (SWR), essentially reflection coefficient, typically of an antenna connected to a radio transmitter. This thesis reports on an adaption of this idea. The first needle shows current into a battery, the second needle indicates the voltage of the battery. There is also a third scale using contour lines which show the amount of time left until the battery is fully charged.
The contour lines are calculated and drawn using analytic geometry by predetermining the rotation of the two needles. Hence the amount of time left for the battery to fully charge can be read by simply looking at where the the two needles cross and estimating from the closest contour line that displays charge time. The input current scale is expanded logarithmically with a wide range from 1mA to 10A. This scale also evenly spreads the contour lines from 10 minutes to 1 week as opposed to a linear current scale, which causes the contour lines beyond 6 hours to cluster making it difficult to observe the charge time at low charge current inputs. The battery voltage scale is offset to suit the battery voltage range.
The meter has been implemented using an embedded microprocessor on a PCB that mounts at the rear of the meter housing. The prototype has been calibrated for a single 18650 Lithium-Ion battery which is a popular scenario for portable equipment. This project provides a manufacturing solution for a low cost, low power, portable Lithium-ion battery monitor which can be easily replicated.

title: The role of honey in the management of wounds

authors: Molan, Peter C.

subjects: biology

abstract: The widespread development of antibiotic-resistant bacteria has generated an increasing interest in the use of alternate therapies for the treatment of infected wounds. In 1989, an editorial in the Journal of the Royal Society of Medicine, referring to reports on the successful use of honey in wounds, stated: 'The therapeutic potential of uncontaminated, pure honey is grossly underutilized.' This paper examines how the chemical and physical properties of honey may facilitate wound healing and offers guidance on practical issues related to clinical use.

title: Mā Muri Ko Mua: An introduction to the issues associated with the translation of the Pene Haare manuscript

authors: Tipene, Jillian

subjects: translation

abstract: Keywords: translation; translation theory; translation practice; Ngakuru Pene Haare; Te Rarawa; manuscript; Māori-English translation; ethically grounded translation.

In September 2007, a copy of a typewritten transcript of a manuscript dated 1923 and written by Ngakuru Pene Hare was given to a member of staff of the University of Waikato by Stephen Burke and Bella Wade, descendants of the author, who requested that the University provide a scholarly treatment and translation into English of the text. Also provided later were copies of letters written by the author and a copy of the original handwritten manuscript. The original manuscript, written in the Te Rarawa ki Hokianga dialect of te reo Māori of the author's time, consists of 239 leaves and contains accounts of at least 62 Ngāpuhi battles, most of which took place between 1820 and 1840. 

The research reported here seeks to identify issues and problems that must be addressed if a competent and ethically-grounded translation is to be produced.  Among the issues and problems identified are a number of critical ones. These include the paucity of information that is publicly available about the author, the context in which he lived and worked and the events about which he wrote. Also identified as being problematic are aspects of the text itself. Thus, for example, many of the conventions associated with contemporary writing in Māori (such as paragraphing and the signalling of word and sentence boundaries) are applied only sporadically. Some of the words and expressions used are archaic and/or esoteric, and symbolism that is deeply culturally-embedded characterises much of the text. Also of significance is the impact of writing on conventions associated with the oral transmission of information. The author's intention in producing the text is also identified as being of fundamental importance in relation to the process and product of translation, as are issues associated with the putative readership of that translation. Of paramount importance is the sacred and sensitive nature of the text itself and much of its content. 

In addressing these issues, a wide range of sources are drawn upon. These include the text itself and the transcription of the text, letters and other material written by, or directly influenced by the author, photographs that reveal important information about him, and a wide range of sources of information and opinion (written and oral) about the author and/ or the times and places in which he lived and the events about which he wrote. Also drawn upon is literature in the areas of linguistics and discourse analysis and the theory and practice of translation, including literature written by the growing number of Māori scholars who have focused on issues associated with translation involving Māori and English.

Among the recommendations made are that the translation, a gloss translation that includes explanatory notes, be undertaken, with tikanga Māori as guiding principles, under the mentorship of knowledgeable elders and in consultation with those to whom the manuscript belongs.
