On the potential use of radar-derived information in operational numerical weather prediction

Estimates of requirements likely to be levied on a new observing system for mesoscale meteonology are given. Potential observing systems for mesoscale numerical weather prediction are discussed. Thermodynamic profiler radiometers, infrared radiometer atmospheric sounders, Doppler radar wind profilers and surveillance radar, and moisture profilers are among the instruments described

Towards a normalisation of young people’s drinking practices: a Chicago school ethnographic study in the Canterbury night-time economy

This PhD thesis is an ethnographic investigation into the drinking practices of young people undertaken in the Canterbury (Kent, United Kingdom) night-time economy. This research took place across a series of fieldwork sites, including: pubs, night-clubs, the street, and young people’s houses across the city. The research included an in-depth ethnography which took place in a city-centre pub where I was working as a bartender, which adapted the methodological approach of the Chicago School of Sociology to urban studies in a contemporary context. Specific examples from the research included a case study with two young men in the pub who were drinking after work, and a wide-range of other ethnographic examples taken from scenarios arising through my position at the pub resulting from bar conversations and informal interviews. These were selected from a number of literally thousands of young people who I encountered across the two years of fieldwork in the pub. The licensee of the pub, Andrew, acted as a gatekeeper for the research, as his approach to the pub business corresponded to interaction and the possibility of building ethnographic relationships with young people. Other ethnographic data examples were also taken from the wider Canterbury night-time economy, away from the pub at the centre of the in-depth ethnography. The variety of data sets included participant observation, conversation, informal interviews and the field diary. Drawing from the accounts of participants in the fieldwork and emergent themes in the ethnography, the thesis argues that young people are the subject of a normalization of extreme drinking practices in the night-time economy. This is explored through the adaptation of the model of drug normalization theory, where young people’s experiences of alcohol and extreme drinking practices are examined in relation to specific dimensions of drinking. The media stereotyping of extreme drinking practices by young people is also subject to critique, where it will be argued that the term “binge” drinking is an imprecise and moralistic view of young people’s activities in the night-time economy

Annotated Records of Species of Pentatomoidea (Hemiptera) Collected at Lights

Records of specimens of Pentatomoidea collected at various light sources in Alabama, Arizona, Florida, Georgia, Illinois, Louisiana, and Texas are presented. Of the 51 species and subspecies reported, about 75% belong to the Pentatomidae

A List of the Scutelleroidea of the La Rue-Pine Hills Ecological Area with Notes on Biology

A survey of the scutelleroid fauna of the LaRue-Pine Hills Ecological Area, Union County, Illinois was conducted from May, 1972 to September, 1974. Forty-nine species were collected, five of which were state records. The remaining 44 represented over 57% of the species presently listed for Illinois. Life history information was collected for the majority of species, including host plants, predators and parasites. The pertinent literature is summarized for each species

The First Records in Illinois of \u3ci\u3eHeliconius Charitonius\u3c/i\u3e (Lepidoptera: Heliconiidae) and \u3ci\u3ePhoebis Agarithe\u3c/i\u3e (Lepidoptera: Pieridae)

(excerpt) Our key to Illinois butterflies, exclusive of the skippers (Hesperiidae), was published in 1980. It includes those butterflies listed by Irwin and Downey in their 1973 Illinois checklist plus two species,Anaea aidea (Guerin-Meneville) (Nymphalidae) and Celastrina ebenina Clench (Lycaenidae), added to the state list after 1973

A List of the Butterflies (Lepidoptera: Papilionoidea) of the La Rue-Pine Hills Ecological Area

A survey of the adult butterfly fauna of the La Rue-Pine Hills Ecological Area, Union County, Illinois, was conducted from March through July in 1979, and March through November in 1980. Forty nine species and subspecies were collected including all six papilionids known to occur in Illinois. Notes were taken on seasonal flight periods and butterfly-plant associations

Material technology

Advanced high pressure O2/H2 propulsion systems as exemplified by the Space Shuttle Main Engine (SSME) create challenging operating environments for materials. Many components operate in either hydrogen or hydrogen-steam environments which may significantly degrade the performance of common alloys. The objective of the materials technology projects is to develop and evaluate candidate materials for application in advanced high pressure O2/H2 propulsion systems. These new and improved materials are to improve the durability or performance of the SSME or derivative engine. The program includes projects on the following topics: (1) Hydrogen Resistant Alloys; (2) High Pressure O2 Ignition and Burning; (3) Improved Turbine Blades; (4) Improved Turbine Disk Material; (5) Impact Reactivity in High Pressure O2; and Fiber Reinforced Superalloys

Diversity and Community Structure of Stream Insects in a Minimally Disturbed Forested Watershed in Southern Illinois

The Lusk Creek Watershed, located in Pope County, IL, long has been rec- ognized as a high quality area of biological significance, but surveys of the stream macroinvertebrate fauna have been limited. Thus, a survey of the benthic insect community at 11 sites in the upper portion of Lusk Creek was conducted from May 2003 to April 2005. A total of 20,888 specimens, mostly immatures, were examined during the study and represented eight orders. The Diptera, by far, was the most abundant order, with 18,590 specimens, almost all of which were members of the Chironomidae or Simuliidae. Members of the EPT (Ephemer- optera, Plecoptera, Trichoptera) contributed 1,550 specimens. The Coleoptera was represented by 647 specimens, most of which were members of Stenelmis (Elmidae) (n = 612). The Shannon diversity index (H ́) ranged from 1.07-2.01 for individual sites and was indicative of relatively undisturbed streams in this region. Jackknife analyses of richness estimated that as many as 37 taxa were unobserved in this survey. Results provide information on reference conditions in the region and a foundation for future monitoring

A comparison between single sided and double sided friction stir welded 8mm thick DH36 steel plate

As part of an ongoing process to fully evaluate the potential for friction stir welding (FSW) to be used in the shipbuilding industry, a comparison has been made between two variants of the process. 8mm thick DH36 steel plate was friction stir welded using a single sided and a double sided process. An assessment of the processes was made to report on the resultant distortion behaviour, hardness, yield strength, toughness and microstructure. As a further comparison, additional work on 8mm thick submerged arc welded (SAW) DH36 plate has been included as the current shipbuilding benchmark. The overall process feasibility will be assessed including the issue of the requirement to rotate the workpiece through 180° to complete the second side of the double sided process
