By the pleasing countenance of my superiors : the life of Dungog magistrate Thomas Cook, J.P.
No full textThomas Cook, Esq. J.P. was one of many immigrants of middling income and status who early in their life threw in their lot with the young Colony of NSW. Like many, Thomas Cook made his contribution without achieving a major place in the history books or leaving behind enough of a record to present a complete picture of his life. Nevertheless, sufficient can be found to provide some fascinating glimpses of the man, the magistrate and of the village of Dungog in the mid-nineteenth century. Thomas Cook, father, Presbyterian, magistrate, J.P., letter writer, horse breeder, landowner, opener of bridges, speech-maker, and at times a figure of some controversy. Despite this list, our picture of the man remains incomplete and the temptation to fill in the gaps in the manner of Gordon Bennett is great, though in modern times we might emphasise his family relations and political interactions over the number of floggings meted out or murderous convicts encountered. For the time being, until further information is uncovered, we must be content with what tantalising glimpses the often sketchy historical record has left us
Voice Compression and Communications: Principles and Applications for Fixes and Wireless Channels
No full textUp-to-date, expert coverage of topics in wireless voice communications Voice communication is the most important facet of mobile radio service. Even when the predicted surge of wireless data and Internet services becomes a reality, voice will remain the most natural means of human communication. Voice Compression and Communications details issues in wireless voice communications and treats compression, channel coding, and wireless transmission as a joint subject. Part I covers background material, whereas Part II provides detailed information on both proprietary and standardized analysis-by-synthesis codecs, including the speech codecs of virtually all existing wireline-based and wireless systems. Parts III and IV discuss mainly research-based wideband, audio, as well as very low-rate schemes likely to find their way into future standards. Voice Compression and Communications describes fundamental concepts in a non-mathematical way early in the book for those with only a background knowledge of signal processing and communications. More advanced readers will find detailed discussions of theoretical principles, future concepts, and solutions to various specific wireless voice communications problems
Hospital food service: a comparative analysis of systems and introducing the ‘Steamplicity’ concept
No full textBackground Patient meals are an integral part of treatment hence the provision and consumption of a balanced diet, essential to aid recovery. A number of food service systems are used to provide meals and the Steamplicity concept has recently been introduced. This seeks, through the application of a static, extended choice menu, revised patient ordering procedures, new cooking processes and individual patient food heated/cooked at ward level, to address some of the current hospital food service concerns. The aim of this small-scale study, therefore, was to compare a cook-chill food service operation against Steamplicity. Specifically, the goals were to measure food intake and wastage at ward level; ‘stakeholders’ (i.e. patients, staff, etc.) satisfaction with both systems; and patients’ acceptability of the food provided.
Method The study used both quantitative (self-completed patient questionnaires, n = 52) and qualitative methods (semi-structured interviews, n = 16) with appropriate stakeholders including medical and food service staff, patients and their visitors.
Results Patients preferred the Steamplicity system overall and in particular in terms of food choice, ordering, delivery and food quality. Wastage was considerably less with the Steamplicity system, although care must be taken to ensure that poor operating procedures do not negate this advantage. When the total weight of food consumed in the ward at each meal is divided by the number of main courses served, at lunch, the mean intake with the cook-chill system was 202 g whilst that for the Steamplicity system was 282 g and for the evening meal, 226 g compared with 310 g.
Conclusions The results of this small study suggest that Steamplicity is more acceptable to patients and encourages the consumption of larger portions. Further evaluation of the Steamplicity system is warranted.
The purpose of this study was to directly compare selected aspects (food wastage at ward level; satisfaction with systems and food provided) of a traditional cook-chill food service operation against ‘Steamplicity’. Results indicate that patients preferred the ‘Steamplicty’ system in all areas: food choice, ordering, delivery, food quality and overall. Wastage was considerably less with the ‘Steamplicity’ system; although care must be taken to ensure that poor operating procedures do not negate this advantage. When the total weight of food consumed in the ward at each meal is divided by the number of main courses served, results show that at lunch, mean intake with the cook-chill system was 202g whilst that for the ‘Steamplicity’ system was 282g and for the evening meal, 226g compared with 310g

Comalco Weipa water quality investigation stage 1
No full text[Extract] Comalco Aluminium Limited Weipa, has commissioned the Australian Centre for Tropical Freshwater Research {ACTFR), as an agent of James Cook University of North Queensland, to undertake an investigation of water quality in a section of the Embley River estuary that is bounded by the Lorim Point sewage treatment plant and the export wharf. A preliminary study brief was provided by Comalco in May 1995.
This was subsequently refined after discussions with Comalco and a site inspection on July IO, 1995.The purpose of the study was to determine the effects of Comalco activities on ambient water quality in the defined study area (shown in Figure I.I) and provide a report in support of a licence application under the new Environmental Protection Act, Environmental Protection Policy (1995) - Water. This work complements the Queensland Ports Corporation/Comalco "Weipa Water and Sediment Baseline Study" that is still in progress. The two investigations differ in that the baseline study seeks to provide a database indicative of existing ambient water quality throughout the greater estuary while the current study focuses on measuring contaminant releases from Comalco operations and localised effects on the quality of receiving waters in close proximity to outfalls. Emphasis has, for instance, been placed on assessing the extent of wastewater mixing zones. Investigations were conducted prior to the 1995-96 wet season and accordingly, provide data indicative of dry season conditions only. Consideration of stormwater releases falls outside the scope of the current study and should ideally be dealt with in separate investigations during the wet season.
The study comprised a number of brief intensive monitoring programs designed to evaluate the quality ,quantity and impact potential of wastewaters released from each environmentally relevant activity (ERA)within the study area. The following ERAs were investigated: Discharges of sewage effluent from the Lorim Point sewage treatment plant (STP); Releases of bauxite laden runoff via the ship loader drain; Spillages of wet bauxite slurry and dust during ship loading operations at the export wharf and, Disposal of power station cooling water (via the "three pipes" cooling water outlet)

Entrainment and detrainment rates from the piv measurements at the top of laboratory analogs of stratocumulus and cumulus clouds
No full textWe analyze mixing at the top of laboratory analogs of convective clouds: stratocumulus and cumulus to investigate entrainment of environmental air into the cloud. We retrieve two components of air velocity using Particle Image Velocimetry technique. Suitable image processing allows to determine cloud–clear air interface. Using velocity differences between cloudy and clear sides of the interface we calculate entrainment / detrainment rates
Vortex Dynamics in The Transitional and Turbulent Wake of 6:1 Prolate Spheroid at 45-deg incidence angle
No full textThe incompressible flow past a 6:1 prolate spheroid with an inclination angle of 45o at Re = 3,000 has been studied by means of direct numerical simulations (DNS). The Reynolds number is based on the inflow velocity and minor-axis length. The preliminary results presented here are focused mainly on vortex dynamics and vortical structures in the wake. The wake behind this configuration starts almost symmetric but is soon strongly deflected and bent as it evolves to the intermediate wake. A pair of unequal-strength vortices dominates the intermediate wake, of which one exhibits the shape of a long vortex tube while the other rapidly breaks down into turbulent-like vortical structures
Experimental characterisation of large scale structures in a high Reynolds number turbulent boundary layer
No full textA very large field of view (4δ x 1δ) with a good spatial resolution owing to the use of four 2k x 2k pixel cameras was conducted in a flat plate boundary layer at two Reynolds numbers (Reθ ≈7,500 and 20,000). Comparing the flow statistics with previously obtained hot-wire data under similar flow conditions show good agreement. The goal of this experiment is to detect and characterise the large scale motions which develop in the log region of a high Reynolds number turbulent boundary layer
