Highlights of a Practicum: The Hattiesburg Coca-Cola Plant Collectibles Museum

The Hattiesburg Coca-Cola museum is currently only opened for special company events and festivities, but there has been discussion of increasing availability to the museum. Even though this collection is currently closed to the public, it is valuable to the company because it generates feelings of pride regarding workers and provides a record of their history working in the community and surrounding area for over 100 years. This paper details the work done in a practicum at the museum

Exploring 19th Century Gift Books in a Special Collection: A Collection Analysis

Descriptions of 19th century literature can be limited because items may be out of print, hard to find, or undocumented. McCain Library and Archives at Southern Miss offers a limited selection of 19th century gift books and annuals; these books can be used to evaluate certain distinct characteristics regarding publishers, dates of publication, authors, and binding styles. This study can help to determine prominent genre characteristics for this era, which may be otherwise difficult to determine considering the scarcity of some of the titles and their editions

Exploring the Position of Humanitarian Engineering in Australia

Context: The position of an engineering field, such as a discipline, specialisation, or area of practice, reflects the body of knowledge, skills and techniques required to practice. Humanitarian Engineering, which was recognised with a 6-digital Field of Research code in 2020, works within a range of contexts and communities where there are inherent power imbalances, and decisions and actions that affect immediate livelihoods and wellbeing. This can be considered similar to fields within Engineers Australia such as Amusement Rides and Devices (an area of practice) and Fire Safety (both an area of practice and technical society). These fields do not have large memberships, but are sufficiently specialised and high risk to require dedicated scrutiny. Humanitarian Engineering can be considered to warrant similar levels of enhanced scrutiny of its practice and education. Purpose: The Engineers Australia Humanitarian Engineering Community of Practice have devised a six-item agenda for the professionalisation of Humanitarian Engineering in Australia. This seeks to bring the same level of rigour, review, and recognition to Humanitarian Engineering as for any field, area of practice or discipline of engineering. This study set out to determine a broad consensus on the position of Humanitarian Engineering within existing frameworks in response to the agenda. Approach: The study adopted a modified Delphi method in which key stakeholders and representatives of Humanitarian Engineering education and practice in Australia were invited to a workshop to openly discuss and debate the position of Humanitarian Engineering in Australia. A pre-workshop survey established a starting point for discussion at a 2-hour workshop while a post-workshop survey identified and tested key insights and findings. Outcomes: A specific position on Humanitarian Engineering in Australia was not reached during the workshop. Rather, underlying assumptions were challenged and tested. Humanitarian Engineering was indeed considered to need higher levels of review and accountability, underpinned by key values and principles. A more specific set of next steps were identified in order to address unresolved questions and provide further analysis to support a potential position. Recommendations: Humanitarian Engineering education and practice should be subject to a high level of scrutiny to ensure appropriate education and practice. Regardless of a specific position and definition, further discussion and critique from within and outside engineering in Australia must continue.Nick J Brown, Jeremy Smith, Scott Daniel and Cris Birze

Natural draft and forced primary air combustion properties of a top-lit up-draft research furnace

Worldwide, over four million people die each year due to emissions from cookstoves. To address this problem, advanced cookstoves are being developed, with one system, called a top-lit up-draft (TLUD) gasifier stove, showing particular potential in reducing the production of harmful emissions. A novel research furnace analogy of a TLUD gasifier stove has been designed to study the TLUD combustion process. A commissioning procedure was established under natural draft and forced primary air conditions. A visual assessment was performed and the temperature and emissions profiles were recorded to identify the combustion phases. The efficiency was evaluated through the nominal combustion efficiency (NCE = CO2/(CO2 + CO)), which is very high in the migrating pyrolysis phase, averaging 0.9965 for the natural draft case. Forced primary air flows yield similar efficiencies. In the lighting phase and char gasification phase the NCE falls to 0.8404 and 0.6572 respectively in the natural draft case. When providing forced primary air flows, higher NCE values are achieved with higher air flows in the lighting phase, while with lower air flows in the char gasification phase. In the natural draft case high H2 emissions are also found in the lighting and char gasification phases, the latter indicating incomplete pyrolysis. From the comparison of the natural draft with the forced draft configurations, it is evident that high efficiency and low emissions of incomplete combustion can only be achieved with high controllability of the air flow in the different phases of combustion.Thomas Kirch, Paul R.

Corrections to facilitate planar imaging of particle concentration in particle-laden flows using Mie scattering, Part 1: Collimated laser sheets

Planar nephelometry is a laser-based technique of imaging the light scattered from particles to provide information about the local number density of these particles. In many seeded flows of practical interest, such as pulverized coal flames, particle loadings are sufficiently high for the incident laser beam to be severely attenuated. Measurements in these flows are therefore difficult, and limited data are available under these conditions. Laser attenuation experiments were conducted in suspensions of spherical particles in water at various concentrations. This is used to formulate a calibration for the effects of diffuse scattering and laser sheet extinction. A model for the distribution of light through a heavily seeded, light-scattering medium is also developed and is compared with experimental results. It is demonstrated that the scattered signal may be considered proportional to the local particle concentration multiplied by the incident laser power. The incident laser power varies as a function of the attenuation by obscurement. This correction for planar nephelometry images thus extends the technique to provide pseudoquantitative data for instantaneous particle concentration measurements.Peter A. M. Kalt, Cristian H. Birzer, and Graham J. Natha

Particulate emissions from a wood-fired improved biomass stove

Worldwide, approximately three billion people cook their food using biomass fuels such as wood, charcoal, crop residues, and animal dung. The emissions produced by these smoky fires lead to four million premature deaths annually and large environmental consequences. While the negative effects of biomass burning have spurred much research into designing less polluting cookstoves, researchers need a knowledge-base to draw from when making design decisions. However, previous research has measured these emissions relatively far away from the source, not exploring how the design modifications affect the actual combustion. In this study, the emissions from an improved cookstove, the Berkeley-Darfur Stove, and single blocks of wood are examined in-situ using laser extinction. The pollutant production, measured by the opacity or soot volume fraction, was compared between the two systems to gain a deeper understanding of combustion in the stove while providing initial steps towards a non-intrusive sampling system for pollutant production in cookstove combustion chambers.Kathleen M.
