Polyinclusive strategies for the development of cities
The defining characteristic of the modern global city today is its excluding character. The city today consists to a large extent of poor people who have been excluded in the process of urban planning and whose right to be a part of the urban process has been largely ignored. Urban development that is geared to the needs of global capital displaces or excludes poor segments of the population and leads to the social and spatial segmentation of the mega-city into citadels and ghettos. This has created a growing disparity between “haves” and “have-nots”, both between and within nations. Globalisation proceeds selectively, including and excluding segments of economies and societies in and out of the networks of information, wealth and power that characterise the new dominant system. In the given perspective this paper attempts: · To analyse the effects of globalisation on urban growth and development in India. · To examine the policy and strategy of urban development during the past two and a half decades, including the organisational structure for managing urban sector schemes and the supporting financing system. · To suggest an integrated strategy for the development of inclusive cities. · To develop a framework of an inclusive, modern and environment friendly city.Inclusive cities;globalisation;Urban planning
Distribution of freshwater fish in the south-western corner of Australia
This study investigates the distribution of freshwater fishes in the Busselton to Walpole Region. A total of 311 sites in 19 major catchments along the south-west coast from Capel to Walpole, were sampled using a variety of methods. New data was collated with that from previous studies to generate 15 species distribution maps. Habitat and life history notes and recommendations for conservation are made for each species. Changes in fish distribution are also commented upon.
This study contributes to series of documents published for the purposes of water allocation planning in the Busselton to Walpole Region
Distribution, identification and biology of freshwater fishes in south-western Australia
A total of 410 sites in the major watersheds in the south-western corner of Australia, bounded by Bunbury in the north-west and just east of Albany in the south-east, were sampled for fish. Sampling of the different sites was carried out using one or more of the following methods, namely seine netting, scoop netting, trapping and electrofishing to catch juvenile and adult fish, and light trapping, scoop netting and haul netting to collect larval fish. The fish caught at each site were identified and the number of each species recorded. These data were then collated, both with those derived from the studies of Christensen (1982) and Jaensch (1992) and with the records of the Western Australian Museum (WAM), to elucidate the distributions of each of the fish species found in freshwater in south-western Australia. The eight species endemic to south-western Australia are Tandanus bostocki, Lepidogalaxias salamandroides, Galaxias occidentalis, Galaxiella nigrostriata, Galaxiella munda, Bostockia porosa, Edelia vittata and Nannatherina baIstoni. The other species found in this region include Galaxias truttaceus and Galaxias maculatus, which are also represented in south-eastern mainland Australia and Tasmania, the anadromous lamprey Geotria australis, and those teleosts which are commonly found in freshwater, but belong to predominantly marine families, i.e. Leptatherina wallacei, Pseudogobius olonum and Afurcagobius suppositus. Finally, there are those species that have been introduced into the region, i.e. Oncorhynchus mykiss, Salmo trutta, Gambusia holbrooki and Perca fluviatilis
Distribution of the spotted minnow (Galaxias maculatus (Jenyns, 1842)) (Teleostei: Galaxiidae) in Western Australia including range extensions and sympatric species
Galaxias maculatus was captured from a number of rivers outside its previously known range. In Western Australia, it was formerly only known from rivers and lakes between the Goodga River (Two People's Bay, 30 km east of Albany) and the Dailey River (50 km east of Esperance), with additional records from the Boat Harbour Lakes (Kent River). An intensive survey of the inland fishes in rivers and lakes along the south coast of Western Australia has extended its distribution east by 50 km (Thomas River), west by approximately 40 km (Walpole River) and north by 400 km (Harvey River). The Western Australian Museum also has a specimen from the Canning River, a further 100 km north. Field salinity tolerance of G maculatus was high, with fish found alive in 81 mScm 1 (-45 ppt). The freshwater piscifauna east of, and including, the Pallinup River is depauperate, with G. maculatusbeing the only freshwater species present. All sympatric teleosts are tolerant of salinity and, with the exception of the introduced Gambusia holbrooki, are estuarine, including Pseudogobius olorum, Leptatherina wallacei and Acanthopagrus butcheri
Transfer of ultra-low phase noise microwave references over the JANET Aurora fibre network using a femtosecond optical frequency comb
An ultra-low phase noise microwave frequency is transferred over 82 km of installed fibre by propagation of a 30 nm bandwidth optical frequency comb (104 modes). The phase noise induced along the fibre by vibrations and thermal effects is suppressed by implementing a noise cancellation scheme where a portion of the light is sent back to the transmitter through the same fibre. The 6th harmonic of the repetition rate detected before and after the pulse train has travelled a round trip are phase compared and used to generate an error signal that controls a fibre stretcher to compensate for the fibre-induced phase fluctuations. Optical amplifiers are used to compensate for the fibre attenuation and dispersion compensation modules are also employed
Effect of Q-switched laser surface texturing of titanium on osteoblast cell response
Titanium and its alloys are important biomedical materials. It is known that the surface texture of implanted medical devices affects cell response. Control of cell response has the potential to enhance fixation of implants into bone and, in other applications, to prevent undesired cell adhesion. The potential use of a 100W Q-switched YAG laser miller (DMG Lasertec 60 HSC) for texturing titanium is investigated. A series of regular features with dimensions of the order of tens of micrometers are generated in the surface of titanium samples and the cell response to these features is determined. Characterisation of the laser milled features reveals features with a lengthscale of a few microns superposed on the larger scale structures, this is attributed to resolidification of molten droplets generated and propelled over the surface by individual laser pulses. The laser textured samples are exposed to osteoblast cells and it is seen that cells do respond to the features in the laser textured surfaces
Polyinclusive strategies for the development of cities
The defining characteristic of the modern global city today is its excluding character. The city today consists to a large extent of poor people who have been excluded in the process of urban planning and whose right to be a part of the urban process has been largely ignored. Urban development that is geared to the needs of global capital displaces or excludes poor segments of the population and leads to the social and spatial segmentation of the mega-city into citadels and ghettos. This has created a growing disparity between “haves” and “have-nots”, both between and within nations. Globalisation proceeds selectively, including and excluding segments of economies and societies in and out of the networks of information, wealth and power that characterise the new dominant system.
In the given perspective this paper attempts:
· To analyse the effects of globalisation on urban growth and development in India.
· To examine the policy and strategy of urban development during the past two and a half decades, including the organisational structure for managing urban sector schemes and the supporting financing system.
· To suggest an integrated strategy for the development of inclusive cities.
· To develop a framework of an inclusive, modern and environment friendly city

Recreational Fishing Initiatives Fund Final Report: Can recreational fishers provide a cost effective means for monitoring artificial reefs?
Artificial reefs have been constructed and deployed in over 50 countries around the world to enhance the productivity of aquatic habitats and fishing experiences. In April 2013, two purpose-built concrete artificial reefs were deployed in Geographe Bay, Western Australia to provide additional fish habitat and increase upwelling and thus enhance recreational fishing opportunities. Due to the relatively high cost of planning, purchasing and deploying these structures, it is important to understand spatial and temporal usage of the reef by fish assemblages, in order to determine the extent to which fishing opportunities are actually enhanced. One potential method to reduce monitoring costs is to utilise volunteers from the general public to collect data, i.e. citizen science. The overall objective of this project was to determine whether recreational fishers, through a citizen science program, could potentially provide an effective means for monitoring artificial reefs
Quasi-static analysis of hip cement spacers
The use of temporary hip prosthesis made of orthopedic cement (spacer) in conjunction with antibiotics became a widespread method used for treating prosthetic infections despite the fact that this method makes bone cement (PMMA) more fragile. The necessity to incorporate reinforcement is therefore crucial to strengthen the bone cement. In this study, a validated Finite Element Modelling (FEM) was used to analyze the behavior of spacers. This FEM model uses a non-linear dynamic explicit integration to simulate the mechanical behavior of the spacer under quasi-static loading. In addition to this FEM, Extended Finite Element Method (XFEM) was also used to investigate the fracture behavior of the spacers reinforced with titanium, ceramic and stainless-steel spacer stems. The effect of the material on the performance of the reinforced spacers was also analyzed. The results showed that numerical modelling based on explicit finite element using ABAQUS/Explicit is an effective method to predict the different spacers' mechanical behavior. The simulated crack initiation and propagation were in a good agreement with experimental observations. The FEM models developed in this study can help mechanical designers and engineers to improve the prostheses’ quality and durability.</p
