Anything is Pawsable: The Connection Between Breed and People\u27s Perception of Service Dogs

Compared to other animals, dogs appear to have the most excellent ability to understand humans’ nonverbal communication and social cues (Lucidi, Bernabo, Panunz, Villa, & Mattiolo, 2005). Service dogs provide a variety of different services and emotional support to their handlers. Additionally, specific breeds of service dogs must have distinct qualities, be particular sizes, and have specific temperaments to do their jobs adequately. Service dogs are defined in the ADA as any dog that is individually trained to do work or perform tasks for the benefit of an individual with a disability, including a physical, sensory, psychiatric, intellectual, or other mental disability. To most of the population, basic knowledge about service dogs is not well known, and few researchers have focused on service dogs regarding the knowledge individuals have and the specific types of service dogs used by people with disabilities. Without this basic knowledge, people are unsure of the proper ways to interact with service dogs. My goal was to survey a sample of the population to examine their prior knowledge about service dogs, and then ask them to rate three different breeds of dogs (Yorkshire Terrier, Golden Retriever, and Pitbull) on their ability to be a service dog. With the hope to bridge the gap between the increasing number of service dogs being used and the knowledge that comes along with interactions between individuals with and without service dogs. There were significant differences between each dog breeds

THE ROLE OF 56th (INDEPENDENT) INFANTRY BRIGADE DURING THE NORMANDY CAMPAIGN JUNE-SEPTEMBER 1944

Comprised of three regular battalions of infantry, 2nd Battalion The South Wales Borderers, 2nd Battalion The Essex Regiment, 2nd Battalion The Gloucester Regiment and Brigade HQ, 56th (Independent) Infantry Brigade was only formed in early March 1944. Its specific task was to land 'under command' of 50th (Northumbrian) Infantry Division on D-Day. This Division itself was made up of three brigades of very experienced infantry. What is remarkable is that 56th Infantry Brigade's infantry battalions had all been on Home Service since June 1940 and were not experienced in battle. Despite this, within only thirteen weeks of formation, 56th Infantry Brigade task was to land on Gold Beach on D-Day as follow up troops and fight inland taking the town of Bayeux by nightfall. After this the Brigade was expected to provide infantry for 7th Armoured Division in a quick push south to take Villers-Bocage. This study traces the journey made by the three battalions of 56th Brigade from 1940 through to a very concentrated forming up and training period specific to the Normandy landings in 1944. It follows their actions from the landings through to the taking of Le Havre in September 1944, by which time the Brigade had served in four different divisions and lost its 'Independent' title to become a permanent member of 49th (West Riding) Infantry Division for the remainder of the war in North West Europe. No study has previously been made of 56th Infantry Brigade and extensive use has been made of primary evidence from The National Archives and other sources in this investigation. A considerable amount of new evidence has been gathered by interviews with surviving veterans of 56th Infantry Brigade. The evidence is used to explore issues that shed new light on life in the Army at home during the war, training for war and the Normandy Campaign

Inheritance of Regrowth and Other Characters in Smooth Bromegrass

Land utilization is becoming increasingly important; farmers and ranchers are continually striving to produce more from production sites and to realize some production from their presently non-productive areas. Progress in this direction must be forthcoming in all areas of agriculture. In the case of cool-season grass species, growth takes place in the spring and fall of the year. With the exceptions of the cool-season grass species, orchardgrass, Dactylis glomerata L., little if any mid-summer growth is produced. Orchardgrass, however, is not winter-hardy or very productive under dryland conditions in South Dakota. Currently, there are no cool-season grass varieties recommended to the farmers and ranchers of South Dakota that could satisfy the need for mid-summer, cool-season grass production. Smooth bromegrass, Bromus inermis L., is extremely winter-hardy, productive, widely-adapted, and generally accepted in South Dakota. For these reasons, development of a variety of smooth bromegrass that has the ability to use moisture and soil nutrients for mid-summer production was undertaken. The objective of this research was to study the inheritance of regrowth, persistence and other characters of seven clones selected for regrowth Gross (1974)

A comparison study into low leak rate buoyant gas dispersion in a small fuel cell enclosure using plain and louvre vent passive ventilation schemes

Hydrogen, producing electricity in fuel cells, is a versatile energy source, but with risks associated with flammability. Fuel cells use enclosures for protection which need ventilating to remove hydrogen emitted during normal operation or from supply system leaks. Passive ventilation, using buoyancy driven flow is preferred to mechanical systems. Performance depends upon vent design, size, shape, position and number. Vents are usually plain rectangular openings, but environmentally situated enclosures use louvres for protection. The effect of louvres on passive ventilation is not clear and has therefore been examined in this paper. Comparison ‘same opening area’ louvre and plain vent tests were undertaken using a 0.144 m3 enclosure with opposing upper and lower vents and helium leaking from a 4 mm nozzle on the base at rates from 1 to 10 lpm, simulating a hydrogen leak. Louvres increased stratified level helium concentrations by typically in excess of 15 %. The empirical data obtained was also used in a validation exercise with a SolidWorks: Flow Simulation CFD model, which provided a good qualitative representation of flow behaviour and close empirical data correlations

How to pack trapezoids: exact and evolutionary algorithms

The purposes of this paper are twofold. In the first, we describe an exact polynomial-time algorithm for the pair sequencing problem and show how this method can be used to pack fixed-height trapezoids into a single bin such that interitem wastage is minimised. We then go on to examine how this algorithm can be combined with bespoke evolutionary and local search methods for tackling the multiple-bin version of this problem—one that is closely related to one-dimensional bin packing. In the course of doing this, a number of ideas surrounding recombination, diversity, and genetic repair are also introduced and analysed

Modelling hazardous distances for large-scale liquid hydrogen pool releases

Abstract An analysis has been carried out using a CFD model (FLACS) to simulate large-scale liquid hydrogen (LH2) pool releases to examine their behaviour and predict the LH2 pool size, downwind hazardous distance, and flammable mass of the hydrogen-air clouds formed for different environmental conditions and release scenarios. The FLACS pool model reproduces similar qualitative trends with regard to the effect of spill rate, spill duration and wind speed on the flammable cloud extent to those observed in the NASA WSTF experimental tests, although significant quantitative differences in the results are also apparent. FLACS simulations were also performed for a number of different transient and continuous LH2 spill release rates to predict the maximum downwind hazardous distances as a function of the LH2 spill release rate. The results are intended to assist with assessing the safety of future LH2 aircraft and airport LH2 storage facilities, being considered as part of the EU ENABLEH2 project

Turf for erosion and sediment control - construction of an Australian national demonstration facility

Turfgrass has been found to be an effective measure for the control of soil erosion and also for the capture of sediment. Previous research quantifying the capability of turfgrass for this purpose was undertaken and communicated, but did not lead to a substantial increase in market share for erosion control by turfgrass in Australia. The Australian turfgrass production industry has therefore invested substantial resources into the design, construction and operation of a new national Erosion and Sediment Control Demonstration Facility at Cleveland, Queensland, as a technical extension tool. The facility has been designed to demonstrate turf as an erosion control and sediment capture measure compared to other products available on the market including silt fencing, silt socks, coir logs and hydro-seeding. This is the only such facility in Australia and has been met with substantial enthusiasm by the turf and erosion industries as well as local and state government representatives. The construction of this facility presented a number of challenges (described in this paper), and is now becoming a critical extension tool for the turfgrass industry to build the erosion control market share for natural turf

Causes, Consequences and Prevention of Refrigeration Fires in Residential Dwellings

There are around 300 residential dwelling fires in Great Britain each year where a fridge or freezer is cited as the cause. A number of these incidents have resulted in injuries/fatalities and produced significant levels of property damage. This paper examines the causes and consequences of refrigeration fires in residential dwelling fires in Great Britain (London and England) and the evidence collected via fire investigation of residential dwelling fires involving fridges or freezers. Analysis of the data collected from these fires suggests that, once ignition occurs, fires started by faults in fridge/freezers are more likely to spread beyond both the appliance and the room of origin, and tend to cause more damage than fires started by the other types of white goods appliance (washing machine, dishwasher or tumble dryer). A number of common failure modes leading to ignition in domestic refrigeration fires, along with specific fire escalation and spread mechanism are identified. Based upon the information obtained from fire investigations and a comparison between the design and construction of refrigeration appliances used in Great Britain and USA, a number of recommendations are suggested which could be used to help reduce the risk of domestic refrigeration fires
