Photographs

This object is a caricature reminiscent of the plate ""Have you any flesh coloured silk stockings...?"" from E.W. Clay's racist satiric series, Life in Philadelphia, originally published in the late 1820s and early 1830s. Depicts an African-American man dressed as a woman, sitting in front of the counter of a dry goods store and inquiring about a pair of dark stockings which ""she"" holds. A smiling female sales clerk assists the customer while displaying a second pair of dark stockings. Bolts of fabric rest on shelves behind the clerk, socks and hosiery hang above, and a white female customer shops …

Transdiaphragmatic Intercostal Hernia Repair In A Patient With Previous Thoracic Surgery, Lilyan T. Starkey, Ruth P. Gerola, David A. Denning

Marshall Journal of Medicine

A transdiaphragmatic intercostal hernia (TDIH) describes the herniation of abdominal contents through diaphragm and chest wall defects. It has been documented following traumatic injuries as well as after episodes of increased thoracoabdominal pressure. However, those resulting from iatrogenic cause remain uncommon and are less often recorded. We report an iatrogenic TDIH in a patient presenting 39 days after a complicated thoracic procedure, highlighting the surgical technique used for successful hernia reduction, diaphragmatic closure, and rib re-approximation. The case reinforces the possibility of a TDIH occurring as a post-surgical complication. Surgeons should anticipate the potential development of TDIH, particularly after thoracic …

Propofol Related Infusion Syndrome: A Subtle Adversary, Brandon Harris, Elizabeth C. Taylor, John W. Pickstone, Errington C. Thompson Md

Marshall Journal of Medicine

Propofol Related Infusion Syndrome (PRIS) was first described in 1998. It has a strange collection of symptoms, including marked bradycardia, persistent, recalcitrant metabolic acidosis, liver enlargement, rhabdomyolysis, and lipemic blood. We present two recent patients who appeared to have had PRIS. Creatinine kinase seems to be an early detector of PRIS. If PRIS is recognized early, this complex metabolic process seems to be completely reversible.

A Taxonomy Of Applied Research Categories As An Aid To Research Pertaining To Aviation, David Trafimow

International Journal of Aviation Sciences (IJAS)

Based on the notion that applied research can be theoretically grounded or not theoretically grounded, I suggest that there are roughly four categories within which quality work in this area can fall: basic research, auxiliary assumptions, theory combined with auxiliary assumptions, and research without theory. Although the importance of auxiliary assumptions in traversing the distance between theories and their applications cannot validly be denied, applied researchers, including those in the aviation area, often have ignored them. But auxiliary assumptions play an important role in understanding the four categories that I propose. Finally, I argue that much of the applied research …

Avionics Market Forecasting: Comparing The Performance Of Artificial Neural Networks Forecasting With Traditional Forecasting Techniques, Jason Alexander Hoop, Walter Rodriguez

International Journal of Aviation Sciences (IJAS)

Avionics can be thought of as the nervous system sustaining aircraft operations, and accurate forecasting is critical in predicting system demand. Modeled after their biological counterpart, artificial neural networks (ANNs) maintain the ability to recognize trends in chaotic and nonlinear systems. These models possess the capability to produce more accurate predictions than those of traditional forecasting methods. The purpose of this paper is to provide a comprehensive overview of ANNs and detail the use of these techniques as a tool for forecasting in the avionics field. Furthermore, it introduces and examines several commonly used types of predictive ANNs. The performance …

Moving Towards Unmanned Aircraft Systems Integration Into The National Airspace System: Evaluating Visual Observers’ Imminent Collision Anticipation During Day, Dusk, And Night Suas Operations, Igor Dolgov

International Journal of Aviation Sciences (IJAS)

An experiment was conducted in an austere desert location (entirely lacking artificial light pollution) to evaluate visual observers’ ability to maintain line of sight with a light-sport manned aircraft and a small unmanned aircraft system (sUAS; Raven RQ-11B or Wasp III) and predict imminent collisions between them. We investigated the impact of night and dusk operational settings on observers’ performance as compared to daytime and manipulated the placement of the critical visual observer in relation to the sUAS pilot. Analyses revealed that the light-sport aircraft was identified at significantly farther distances at night and dusk than during the day, and …

General Solution Of The Wind Triangle Problem And The Critical Tailwind Angle, Nihad E. Daidzic Ph.D., Sc.D.

International Journal of Aviation Sciences (IJAS)

A general analytical solution of the navigational wind-triangle problem and the calculation of the critical tailwind angle are presented in this study among other findings. Any crosswind component will effectively create a headwind component on fixed course tracks. The meaning of a route track is lost with excessive crosswinds representing the bifurcation point between the possible and the impossible navigational solutions. Any wind of constant direction and speed will effectively reduce groundspeed and increase time-of-flight on closed-loop multi-segment flights. Effective wind track component consists, in general, of true and induced components. The average groundspeed of multiple-leg flights is a harmonic …

Grassland Productivity And Water Quality: A 21st Century Issue, David M. Nash, P. M. Haygarth

IGC Proceedings (1977-2023)

1. Irrigation and other changes to the hydrological cycle can increase soil and water salinity.
2. Primary salinisation is a natural process that affects much of Europe, Asia, Africa, the Americas and Australia. Secondary salinisation is caused by human activities such as irrigation and land clearing that mobilise salt stored in the soil.
3. The critical water contaminants exported from grasslands are nitrogen, phosphorus, potential pathogens and sediment.
4. The mechanisms responsible for diffuse pollution from grasslands and mitigation strategies are most effectively investigated using a ‘source-mobilisation-transport’ framework.
5. There is a lack of coherent interaction across discipline boundaries that links pollutant sources to impact. …

Water Resources, Agriculture And Pasture: Implications Of Growing Demand And Increasing Scarcity, M. W. Rosegrant, R. A. Valmonte-Santos, S. A. Cline, C. Ringler, W. Li

IGC Proceedings (1977-2023)

1. Water availability for irrigation is threatened in many regions by rapidly increasing demand for nonagricultural water uses in industry, households, and the environment. The scarcity of irrigation water will not only impact crop production, but also meat production, as much of the pasture used to feed livestock is irrigated.
2. Grassland is caught between two countervailing forces: a requirement for increasing meat demand that boosts the need for additional pasture to support livestock production, and rapidly increasing water scarcity that makes pasture irrigation uneconomical.
3. The most effective means of dealing with water scarcity is likely to be conserving water in existing …

Soil Quality Assessment And Management, M. G. Kibblewhite

IGC Proceedings (1977-2023)

1. Soil quality is related to the capacity of soil to deliver ecosystem services on a sustainable basis.
2. Effective management of soil within grasslands can deliver many benefits to mankind but poor management may cause loss of soil quality from erosion, loss of organic matter, physical deterioration etc.
3. Services are delivered from soil by biological processes. Soil quality depends on the form and condition of the soil habitat. Fixed factors (e.g. texture) are useful for assigning soil to types. Variable factors (e.g. organic carbon) can then be used to assess quality within soil types, by reference to percentiles of the distribution …

Soil Microbial Community: Understanding The Belowground Network For Sustainable Grassland Management, Y. G. Zhu, W. D. Kong, B. D. Chen, Z. B. Nan, P. Christie

IGC Proceedings (1977-2023)

1. In addition to the use of conventional methodologies in soil microbial research, molecular techniques are now being applied to gain insights into the soil microbial community;
2. Plant diversity can exert impacts on soil microbial diversity (through root activities and plant litter etc.), but may in itself be significantly altered by soil properties;
3. Soil microbial diversity largely determines the stability of soil ecosystems under biotic and abiotic perturbations.
4. Management of soil microbial diversity can only be achieved through better understanding their structures and functions.

Grasslands1 For Production And The Environment, David R. Kemp, David L. Michalk

IGC Proceedings (1977-2023)

1. To manage grasslands for production and enhanced environmental values requires a redefinition of the frameworks within which management decisions are made, and a tailoring of practices to suit the ways that farmers operate.
2. Improving the perenniality and permanence of grasslands usually leads to better environmental and production outcomes.
3. There is a case for a more conservative approach to utilising grasslands in order to sustain the functioning of local ecosystems and to improve water quality, nutrient and energy cycling and biodiversity.
4. A landscape rather than paddock focus is more appropriate for meeting current grassland management objectives. Grasslands can be triaged to …

The Potential Of Grassland And Associated Forages To Produce Fibre, Biomass, Energy Or Other Feedstocks For Non-Food And Other Sectors: New Uses For A Global Resource, M. F. Askew

IGC Proceedings (1977-2023)

1. In developed countries increased areas of land will become available for non-food production. Recent reforms of the Common Agricultural Policy will further intensify this trend in Europe.
2. There is potential for grassland and associated species to contribute to large tonnage markets of energy and bulk fibres, to the supply of fermentation products and to speciality markets, but processes and approaches to the market are not as yet developed.
3. There is potential for the establishment of Graminaceous species - specifically for non- food use. For European conditions particular attention is being given to Miscanthus sinensis (Miscanthus), Arundo donax (Giant Reed), Phalaris …

1. Plant biopharming is set to dominate commercial recombinant protein expression for specific proteins.
2. The choice of plant species depends on a multitude of factors and is determined on a case- by-case basis.
3. As a leaf based expression system grasses would have to compete predominantly with tobacco and alfalfa.
4. The grass-endophyte symbiosis offers a number of unique possibilities for biopharming.

Adoption Of Tropical Legume Technology Around The World: Analysis Of Success, H. M. Shelton, Steven Franzel, M. Peters

IGC Proceedings (1977-2023)

1. Examples of successful adoption of forage legumes are reported from all continents, where they delivered profitability and often provided multipurpose benefits to farmers.
2. Factors vital to successful adoption were: meeting the needs of farmers; building relevant partnerships; understanding the socio-economic context and skills of farmers; participatory involvement with rural communities; and long-term involvement of champions.
3. Organisation of seed supply, achieving scale-up and forming partnerships to implement adoption are key features.
4. Legumes remain an important but under-exploited resource for tropical farming systems. The alternative to legumes will be greater and more costly use of N-fertilisers and purchased protein concentrates.
5. The R&D …

Evolution Of Integrated Crop-Livestock Production Systems, Martin H. Entz, William D. Bellotti, J. M. Powell, S. V. Angadi, W. Chen, K. H. Ominski, B. Boelt

IGC Proceedings (1977-2023)

1. Many factors contribute to changes in the crop-livestock systems, but no logical end-point in the evolution process exists.
2. While benefits of integrated crop-livestock systems over specialised crop and livestock systems are well documented, there has been a move to specialised crop and livestock production.
3. Sustainability issues (manure nutrient concentration, soil quality maintenance, salinity, herbicide resistance, economic instability) have created a renewed interest in integrated crop-livestock systems.
4. Farmer adaptability is as an important link in the evolution between ‘states of integration’.

Overcoming Seasonality Of Production: Opportunities Offered By Forage Conservation Technologies, P. O'Kiely, A. G. Kaiser

IGC Proceedings (1977-2023)

1. Seasonality of forage supply is a key contributor to the seasonality of meat and milk production.
2. Conserving forages as silage or hay can help reduce the seasonality of feed supply.
3. Forage conservation technologies make this contribution mainly through increases in the yield or quality of suitable crops, through an improved efficiency of the conservation process or by allowing a reduction in costs.
4. Future research needs differ considerably among regions of the world.
