Academic literature on the topic '969999 Environment not elsewhere classified'

PurposeThis research aimed to determine the differences and similarities in each pilot project to understand the primary design forms and concepts of sponge city concept (SCC) projects in China. It also aimed to examine ten pilot projects in Shanghai to extrapolate their main characteristics and the processes necessary for implementing SCC projects effectively.Design/methodology/approachA literature review and field survey case study were employed. Data were mostly collected through a field survey in Shanghai, focusing on both the projects and the surrounding environment. Based on these projects' examination, a comparative method was used to determine the characteristics of the ten pilot SCC projects and programs in Shanghai.FindingsSix main types of SCC projects among 30 pilot cities were classified in this research to find differences and similarities among the pilot cities. Four sponge design methods were classified into ten pilot projects. After comparing each project size using the same geographical size, three geometrical types were categorized into both existing and new city areas. SCC project characteristics could be identified by combining four methods and three geometrical types and those of the SCC programs by comparing the change in land-use and the surrounding environment in ten pilot projects.Originality/valueThe results are valuable for implementing SCC projects in China and elsewhere and future research on the impact of SCC projects.

During the Late Proterozoic a more than 1000 m thick succession of sediments was deposited on the shelf fringing the north-eastern corner of the Greenland craton. These sediments were classified together with an underlying turbidite sequence in the Hagen Fjord Group (Haller, 1961), which is here redefined to contain only Upper Proterozoic, mainly shallow marine shelf deposits outcropping between Independence Fjord and Kronprins Christian Land in eastern North Greenland. Both siliciclastic and carbonate sedimentation occurred during the Late Proterozoic, and the changing tectonic environment along the northern and eastern shelf-margin of Greenland at that time is well recorded within the sediment sequence. Correlation of the Hagen Fjord Group with similar shelf deposits elsewhere along the eastern and northern margin of the Canadian-Greenlandian Shield is discussed.

The metazoan meiobenthos was investigated in an Antarctic coastal sediment (Factory Cove, Signy Island, Antarctica). The fine sands contained much higher abundances compared to major sublittoral sediments worldwide. Classified second after Narrangansett Bay (North Atlantic) they reached numbers of 13 × 106ind m-2. The meiofauna was highly abundant in the surface layers, but densities decreased sharply below 2 cm. Vertical profiles mirrored steep gradients of microbiota, chloropigments and organic matter and were coincident with chemical stratification. Spatial patchiness manifested especially in the surface layer. Nematodes dominated (up to 90%), andAponema, Chromctdorita, Diplolaimella, Daptonema, MicrolaimusandNeochromadoraconstituted almost the entire community. Overall, the nematode fauna showed a strong similarity with fine sand communities elsewhere. The dominant trophic strategies were epistrarum and non-selective deposit feeding, but the applied classification for feeding guild structure of the nematodes of Factory Cove is discussed. High standing stock, low diversity and shallow depth distribution may have occurred because of the high nutritive (chlorophyll exceeded lOOOmgm-2and constituted almost 50% of the organic pool) and reductive character of the benthic environment. These observations must have originated from the substantial input of fresh organic matter from phytoplankton and microphytobenthic production, typical for an Antarctic coastal ecosystem during the austral summer.

Energy storage is a key technology for many purposes and in particular for air conditioning plants and a successful exploitation of solar energy. Thermal storage devices are usually classified as either variable temperature (“sensible heat”) or constant temperature (“latent heat”) devices. For both models a basic question is to determine the efficiency suitably: Only exergy efficiency appears a proper way. The aim of this paper is to examine exergy efficiency in both variable and constant temperature systems. From a general statement of exergy efficiency by the present author, two types of actual definitions are proposed, depending on the fact that the exergy of the fluid leaving the thermal storage during the charge phase can be either totally lost or utilized elsewhere. In addition, specific remarks are made about the exergy of a system in a periodically varying temperature environment.

The multidisciplinary study of the beach of El Jadida and its sediments reflects that its shape is asymmetrical, narrow and contrasting between SE and NW which closely affects marine and wind dynamics and functioning of this beach. As profiles of beaches and the extension of the area affected by the tides, they present an argument for the elevation of the sea level had certainly warming. In addition to the Cretaceous lime stone be drock, the Quaternary calcarenites localized only in the SE richer, even more, this place in carbonate more than elsewhere in particular in winter. El Jadida beach sediments are basically homogeneous and well classified (coarse and fine) and reflect a more or less closed environment. The rocks of the SE affect the marine dynamics in rendering the texture of coarse and slightly heterogeneous sediments especially in winter but the correct classification is on the side fine sediments. The emitting provinces of minerals fuelling El Jadida Beach, via the Oued Oum Rbia and littoral drift, are essentially Jacqueline and Sidi Said Maachou El Jadida beach is under anthropogenic pressure considerable (proliferation of buildings) that promote the reduction of the area of the beach and therefore it creates a malfunction of this and an imbalance between it and marine and wind dynamics. Where urgent intervention and sound management that apply to the protection of this beach and its environment.

The forests of the canton of Uri: the foundation of sustainable development (essay) The canton of Uri is characterised by extreme topography: steep slopes and narrow valleys. Limited space is a major challenge for the development of the canton. Prudent management of this mountainous area is necessary to ensure a safe and attractive environment. In this situation, the forest, or to be more precise, the management of the forest, plays a key role. Most of the forest area is classified as protection forest, which is an essential condition to guarantee safety. The overriding management objective for the protective forest is sustainability. The existence of the forest in all its forms is the necessary condition also for biodiversity and landscape beauty. There is strong demand for land on the valley floor, where the main challenge is to protect the few remaining forest areas. Elsewhere however, the forest is expanding and measures must be taken to stop it taking over completely. Forest operations have consequences beyond the forest borders. For these reasons, sustainable management of the forest resource is the foundation of sustainable development of the mountainous canton of Uri.

Research that identifies behavioral contingents, portions of a population that exhibit alternate life history strategies or habitat preferences, can provide a better understanding of a species’ resilience to disturbances, changes in environmental factors, and harvest. Sightings of the estuarine-dependent common snook Centropomus undecimalis at offshore reef areas throughout the year in southeast Florida prompted an investigation to determine whether a contingent of the snook population remains offshore year-round and if they can contribute to the inshore population. This study employed underwater visual observations, specimen collections, and acoustic telemetry over 7 yr to document and describe the snook that utilize offshore habitat. Fish were observed in groups of up to 225 individuals, 20.4 km from an inlet, and in waters up to 36.6 m deep. Snook were present in 79.4% of dive surveys conducted on artificial reefs but only in 18.4% of surveys on natural reefs. Acoustic telemetry showed that many fish remained offshore for multiple years. Most sampled fish (89.1%) were spawning capable, with some classified as actively spawning (15.8%). Reports of snook using offshore reefs occur elsewhere, including southwest Florida and the Florida Keys, indicating that this contingent behavior may not be unique to southeast Florida. Evaluating these occurrences and identifying potential triggers that prompt snook to leave the estuary for an offshore environment can aid in determining how the offshore contingent affects the overall population.

Greater gliders, Petauroides volans, were radio-tracked within a large tract of forest in the dry inland of southern Queensland. This forest has been commercially logged for timber for more than 100 years. Home-range estimates ranged from 1.4 ha (female) to 19.3 ha (male). Minimum convex polygon (MCP) estimates were larger for males (average, 11.5 ha) than females (average, 3.3 ha) and combined (6.8 ha, sexes pooled) were larger than estimates from other Australian populations. Gliders were located foraging in myrtaceous tree species only, using mostly Eucalyptus moluccana, E. fibrosa and Corymbia citriodora. E. moluccana was used for foraging more frequently than would be expected on the basis of its availability in the forest. E. fibrosa and C. citriodora were used in proportion to their availability in the forest. Gliders were not seen foraging in non-myrtaceous species or myrtaceous trees <20 cm diameter at breast height (dbh), preferring trees in 30–70-cm dbh classes and as ‘mature’ and ‘over-mature’ classified according to growth-stage characteristics. Den tree species included the same species used for foraging as well as dead trees (16% of den trees). E. fibrosa and E. tereticornis were preferred significantly more than expected by their availability in the forest. Non-myrtaceous species were not used as live den trees. Large (dbh >50 cm) and old living trees (in deteriorating and senescent condition: ‘late mature’ and ‘over-mature’ categories) were primarily used as den trees. Individual gliders utilised 4–20 den trees. Females utilised more den trees per unit area of home range (3.8 den trees ha–1, maximum) than males (0.9 den trees ha–1, maximum). Fewer den trees were used per unit area of home range than by gliders at a coastal location with approximately the same latitude. The density of live stems containing hollows suitable as dens is currently lower than 1 tree ha–1 in some parts of the study forest. Gliders were two and half times less likely to be observed during standardised spotlighting surveys in the study area than elsewhere in southern Queensland. It is likely that low availability of den trees is contributing to large home ranges and the apparent low population density observed in this study.

In this era of startling developments in the medical field there remains a serious worry about the hazardous potential of various by products which if not properly addressed can lead to consequences of immense public concern. Hospitals and other health care facilities generate waste products which are evidently hazardous to all those exposed to its potentially harmful effects. Need for effective legislation ensuring its safe disposal is supposed to be an integral part of any country's health related policy. This issue is of special importance in developing countries like Pakistan which in spite of framing various regulations for safeguarding public health, seem to overlook its actual implementation. The result unfortunately is the price wehave to pay not only in terms of rampant spread of crippling infections but a significant spending of health budget on combating epidemics which could easily have been avoided through effective waste disposal measures in the first place. Waste classified under the heading 'bio-hazardous' includes any infectious or potentially infectious material which can be injurious or harmful to humans and other living organisms. Amongst the many potential sources are the hospitals or other health delivery centres which are ironically supposed to be the centres of infection control and treatment. Whilst working in these setups, health care workers such as doctors, nurses, paramedical staff and sanitation workers are actually the ones most exposed and vulnerable to these challenges. Biomedical waste may broadly be classified into Infectious and toxic waste. Infectious waste includes sharps, blood, body fluids and tissues etcwhile substances such as radioactive material and by-products of certain drugs qualify as toxic waste. Furthermore health institutions also have to cater for general municipal waste such as carton boxes, paper and plastics. The World Health Organisation has its own general classification of hospital waste divided into almost eight categories of which almost 15% (10% infectious and 5% toxic) is estimated to be of a hazardous nature while the remaining 85% is general non hazardous content.1A recent study from Faisalabad, Pakistan has estimated hospital waste generation around 1 to 1.5 kg / bed /day for public sector hospitals in the region,2while figures quoted from neighbouring India are approximately 0.5 to 2 KG / hospital bed /day.3 Elsewhere in the world variable daily hospital waste production has been observed ranging from as low as 0.14 to 0.49 kg /day in Korea4 and 0.26 to 0.89 kg/day in Greece5to as high as 2.1 to 3.83 kg/day in Turkey6 and 0.84 to 5.8 kg/day in Tanzania.7Ill effects of improper management of hospital waste can manifest as nosocomial infections or occupational hazards such as needle stick injuries. Pathogens or spores can be borne either through the oro-faecal or respiratory routes in addition to direct inoculation through contact with infected needles or sharps. Environmental pollution can result from improper burning of toxic material leading to emission of dioxins, particulate matter or furans into the air. The habitat can also be affected by illegal dumping and landfills or washing up of medical waste released into the sea or river. Potential organisms implicated in diseases secondary to mismanagement of hospital waste disposal include salmonella, cholera, shigella, helminths, strep pneumonia, measles, tuberculosis, herpesvirus, anthrax, meningitis, HIV, hepatitis and candida etc. These infections can cause a considerable strain on the overall health and finances of the community or individuals affected. The basic principal of Public health management i.e 'prevention is better than cure' cannot be more stressed in this scenario as compared to any other health challenge. Health facilities must have a clear policy on hazardous waste management. To ensure a safe environment hospitals need to adopt and implement international and local systems of waste disposal. Hospital waste management plan entails policy and procedures addressing waste generation, accumulation, handling, transportation, storage, treatment and disposal. Waste needs to be collected in marked containers usually colour coded and leak proof. Segregation at source is of vital importance. The standard practice in many countries is the Basic Three Bin System ie to segregate the waste into RED bags/ boxes for sharps, YELLOW bags for biological waste and BLUE or BLACK ones for general/ municipal waste. All hospital staff needs to be trained in the concept of putting the right waste in relevant containers/ bags. They need to know that more than anything else this practice is vital for their own safety. The message can be reinforced through appropriate labelling on the bins and having posters with simple delineations to avoid mixing of different waste types. Sharps essentially should be kept in rigid, leak and puncture-resistant containers which are tightly lidded and labelled. Regular training sessions for nurses and cleaning staff can be organised as they are the personnel who are more likely to deal with waste disposition at the level of their respective departments. Next of course is transportation of waste products to the storage or disposal. Sanitary staff and janitors must be aware of the basic concepts of waste handling and should wear protective clothing, masks and gloves etc, besides ensuring regular practice of disinfection and sterilization techniques.8Special trolleys or vehicles exclusively designed and reserved for biomedical waste and operated by trained individuals should be used for transportation to the dumping or treatment site. Biomedical waste treatment whether on site or off site is a specialised entity involving use of chemicals and equipment intended for curtailing the hazardous potential of the material at hand. Thermal treatment via incinerators, not only results in combustion of organic substances but the final product in the form of non-toxicash is only 10 to 15% of the original solid mass of waste material fed to the machine. Dedicated autoclaves and microwaves can also be used for the purpose of disinfection. Chemicals such as bleach, sodium hydroxides, chlorine dioxide and sodiumhypochlorite are also effective disinfectants having specialised indications. Countries around the world have their own regulations for waste management. United Kingdom practices strict observance of Environmental protection act 1990, Waste managementlicensing regulations 1994 and Hazardous waste regulations 2005 making it one of thesafest countries in terms of hazardous waste disposal. Similar regulations specific for each state have been adopted in United States following passage of the Medical Waste tracking act 1988. In Pakistan, every hospital must comply with the Waste Management Rules 2005 (Environment Protection Act 1997), though actual compliance is far from satisfactory. It is high time that the government and responsible community organisations shape up to seriously tackle the issue of bio hazardous waste management through enforcement of effective policies and standard operating procedures for safeguarding the health and lives of the public in general and health workers in particular.

Outbreaks, defined as excess cases of a particular disease or illness which outweighs the response capabilities, have the capacity to overwhelm health care facilities and need timely response and attention to details in order to avoid potentially disastrous sequelae . In this day and age when improvement in public health practices have significantly curtailed outbreak of various diseases, certain viral illnesses continue to make headlines. One of the notable vector borne infectious disease affecting significant portions of south east Asia in the early part of twenty first century is 'Dengue fever'. Dreaded as it is by those suffering from the illness, a lot of the hysteria created is secondary to a lack of education and understanding of the nature of the disease and at times a result of disinformation campaign for vested interests by certain political and media sections.'Dengue' in fact is a Spanish word, assumed to have originated from the Swahili phrase -ka dinga peppo -which describes the disease as being caused by evil spirit. 1 Over the course of time it has been called 'breakbone fever', 'bilious vomiting fever', 'break heart fever', 'dandy fever', 'la dengue' and 'Phillipine, Thai and Singapore hemorrhagic fever' Whilst the first reported case referring to dengue fever as a water poison spread by flying insects, exists in the Chinese medical encyclopedia from Jin Dynasty (265-420 AD), the disease is believed to have disseminated from Africa with the spread of the primary vector, aedes egypti, in the 15th to 19th century as a result of globalisation of slave trade 45In 80% of the patients affected by this condition the presentation is rather insidious and at best characterized by mild fever. The classical 'Dengue fever' present in about 5% of the cases is characterized by high temperature, body aches, vomiting and at times a skin rash. The disease may regresses in two to seven days. However inrare instances (<5%) it may develop into more serious conditions such as Dengue hemorrhagic fever whereby the platelet count is significantly reduced leading to bleeding tendencies and may even culminate in a more life threatening presentation i.e Dengue shock syndrome.6To understand the actual dynamics of Dengue epidemic it is important to understand the mode of its spread in affected areas. Aedes mosquito (significantly Aedes Egypti) acts a vector for this disease. Early morning and evening times7 are favoured by these mosquitos to feed on their prey. There is some evidence that the disease may be transmitted via blood products and organ donation. 8 Moreover vertical transmission (mother to child) has also been reported 9Diagnostic investigations include blood antigen detection through NS-I or nucleic acid detection via PCR. IO Cell cultures and specific serology may also be used for confirming the underlying disease. Whilst sporadic and endemic cases are part of routine medical practice and may not raise any alarm bells, outbreaks certainly need mobilization of appropriate resources for effective control. Needless to say 'prevention is better than cure' and should be the primary target of the health authorities in devising strategies for disease control.The WHO recommended 'Integrated Vector control programme', lays stress on social mobilisation and strengthening of public health bodies, coherent response of health and related departments and effective capacity building of relevant personnel and organisations as well as the community at risk. For Aedes Egypti the primary control revolves around eliminating its habitats such as open sources of water. In a local perspective in our city Peshawar, venue of the recent dengue epidemic, it may be seen in the form of incidental reservoirs such as receptacles and tyres dumped in open areas such as roof tops with rain water accumulating in them and provtdjng excellent breeding habitats, Larvicidal and insecticides may be added to more permanent sources such as watertanks and farm lands. There is not much of a role for spraying with organophosphorous agents which is at times resorted to for public consumption. Public education is the key to any effective strategy which must highlight the need for wearing clothing that fully covers the skin, avoiding unnecessary early morning and evening exposure to vector agents, application of insect repellents and use of mosquito nets. It is also important not to panic if affliction with the disease is suspected as in a vast majority of instances it is a self limiting illness without any long term harmful effects and needs simple conservative management like antipyretics and analgesics.An important consideration for responsible authorities in a dengue epidemic is to ensure that maximum management facilities for simple cases are provided at the community level through primary and secondary health care facilities and that the tertiary care hospitals are not inundated with all sort of patients demanding consultation. These later facilities should be reserved for those patients who end up with any complications or more severe manifestation of the disease.Research is underway to develop an ideal vaccine for Dengue fever. In 2016, a vaccine by the name 'Dengvaxia' was marketed in Phillipines and Indonesia. However with development of new serotypes of the virus, its efficacy has been somewhat compromised.As for treatment , there are no specific antiviral drugs. Management is symptomatic revolving mainly around oral and intravenous hydration. Paracetamol (Acetaminophen) is used for fever as compared to NSAIDS such as Ibuprophen infusion as well as blood and platelet transfusion.Data to date shows that slightly more than twenty three thousand people have been diagnosed with dengue over the past three months ie August to October there is a lower risk of bleeding with the former. Those with more severe form of the disease may need Dextran 2017, in Peshawar, Pakistan with around fourteen thousand needing admission and about sixty nine recorded deaths. The mortality is well within the acceptable international standards of less than 1% for the disease. In the backdrop of all the debate surrounding the current epidemic, one can infer that such outbreaks are best addressed with effective planningwell ahead of the time before the disease threatens to spiral out of control. Simple measures such as covering water storage facilities, using larvicidals where practical, use of insect repellents, mosquito nets and avoiding unnecessary exposure can offerthe best protection. Public health messages via print and electronic media can help educate people in affected areas and allay any anxiety building up from a fear of developing life threatening complications. Health department must mobilise all its resources to ensure local management of diagnosed patients with simple dengue fever and facilitate hospital admission only for those suffering from more severe form of the disease. Moreover the media hype into such situations needs to be addressed through constant updates and discouraging any negative politicking on the issue. To sum up Dengue fever is not really an affliction to be dreaded provided it is viewed and managed in the right perspective.

Since the unification of East and West Germany in 1990, most of the urban fabric of the former East Germany has been altered beyond recognition or completely dismantled. However, during the four decades of the German Democratic Republic, public spaces and the works of visual arts within them were the subject of intense critical discussion, and formed the basis for the development of theories on the socialist character of art and architecture, which evolved from the late 1960s as Komplexe Umweltgestaltung "Complex Environmental Design". This thesis makes an original contribution to knowledge by making visible and elucidating the cultural-political significance of that urban visual culture, dematerialised and dispersed since the fall of the Berlin Wall. It examines the political, social and artistic function of murals, paintings, sculptures, applied arts, form design, and visual communication within East German architecture and public spaces, and seeks to complexify the commonly understood historical narrative which traces a rupture from the doctrine of an extravagant Socialist Realism to a form of impoverished Modernism. This change is better understood as a gradual and halting evolution, in which art as a medium for projecting the ideal of socialism was displaced by an understanding of design as a means of sustaining the experience of it. Furthermore, the narratives, formal and material qualities of some of the works examined – overlooked even in contemporary re-appraisals of East German art history – rather than being marginal to Socialist Realism, actually opened up spaces for its development. The thesis centres on forms of public art during and after the transition to the industrial mass production of architecture in the mid 1950s. The early phase in the 1950s is illustrated through the two first industrial cities, Eisenhüttenstadt and Hoyerswerda, built to serve iron and coal production respectively. The "scientific and technological revolution", proclaimed by SED first secretary Walter Ulbricht in the 1960s, was to accelerate the process of modernity, in the understandings of the function of urban planning and the role of design for planning, architecture and consumer culture. This change saw a move towards functionalist-oriented planning for Halle Neustadt (from 1964), the centre of new chemical and synthetics production, and a radical move to modernity in the re-construction of city centres up until 1969. This radical change exposed the conception of architecture as an art (Baukunst) favoured by traditionalists in the Bauakademie in particular, to challenges by modernisers who held that art should be considered as primarily functional and thus separate from art. Complex Environmental Design, as this work will demonstrate, gradually replaced the Socialist Realist ideal of Baukunst and the "synthesis" between art and architecture, and became established by the mid 1970s as an interdisciplinary practice in which all visual art forms – architecture, fine arts, crafts, form design, graphic design and landscape design – were to be integrated within the complex planning of the built environment. I shall argue that this inclusion of all artistic disciplines in the design of the built environment formed a compromise between competing ideas between "synthesis" or the separation of art and architecture. Halle Neustadt was key in the conceptual transition to complex environmental design. The thesis goes on to look at how the artistic conception of the 1973 World Festival Games took up a form of complex environmental design, which functioned as both a new form of monumentality, as well as opening up a space for more democractic forms of public art. Methodologically, the research seeks to understand the influence of key actors in the field who were not resistant to the cultural political framework but sought to mediate change within it. Interviews with architects, critics, artists and designers, including architectural critic Bruno Flierl, architect, Sigbert Fliegel, artists Willi Neubert and Manfred Vollmert, designers, Rolf Walter, Lutz Brandt and Axel Bertram together with analyses of their work, and how their ideas were represented by themselves and others, particularly in professional fora, form the basis for an examination their influence. By looking at historical moments in different loci, it becomes apparent that what I term "clusters of influence" formed which pushed forward conceptual transitions. Key sources are the professional journals in which art and architecture were discussed (Deutsche Architektur, Bildende Kunst, Form und Zweck, Farbe und Raum and Neue Werbung) as well as some news and features aimed at the general public such as Neues Deutschland, Neue Berliner Illustrierte and Für Dich. Archival research has focused on the seminars and congresses organised by the professional institutions, the Verband der Bildende Künstler (Artists Union) and the Deutsche Bauakademie (German Building Academy) as well as the records of the local SED in Halle and a number of offices for architectural art which were established across the GDR in the late 1960s. The search for socialist character both in content and form which had an impact on the visual arts of the built environment in the GDR was informed by shifting definitions of the concepts of "function" and "beauty", in which historical legacies, in particular, the Bauhaus, were critically appropriated in a way which served the sometimes involuntary and sometimes intentional interplay between artistic disciplines. The research reveals how these concepts and legacies were drawn together, and plays particular attention to the way in which colour and ornament emerged as central in serving the need for the constituent parts of the urban landscape to be socialist, functional and beautiful.

This research aims to examine the extent to which cultural agency can be seen to ‘act’ in an ecopolitical context and how its operations urge a rethinking of the processes that govern the production of urban subjects and environment(s). Responding to the fact that in recent decades, art and architectural cultures have converged around a shared concern for ‘ecological matters’ and that discourses in visual/spatial culture have become increasingly ‘ecologized’, this research broadens the points of reference for the term ‘ecology’ beyond that which simply reinforces an essentialist perspective on ‘nature’. The thesis re-directs the focus of current theoretical discourse on ‘ecological art’ towards a more rigorous engagement with its frames of reference and how it uses them to evaluate the role of cultural production in enacting ways of thinking and acting eco-logically. In doing so it develops an eco-logical mode of analysis for mapping and probing the attribution of cultural agency, how it intervenes in the production of the commons and how it discloses the participants and mechanisms of a nascent political ecology. Setting cultural agency within a more expansive and multivalent field of action, means that the nexus of agency (and intentionality) is dislocated and translated between ‘things’. Reconfigured in this way, ‘an ecology of agencing’ demonstrates the profound implications this has for any ‘bodies’ of action, cultural or otherwise. Locating this exploration within the socio-natural environment(s) found in urban spatialities this thesis attends to the relatively under-theorised, but highly significant area (in eco-logical terms) of aesthetic praxis operating at the interstices of art and architecture. Pressing at the boundaries of the formal and conceptual enterprises of both disciplines, critical spatial practices represent a distinctive form of eco-praxis being cultivated ‘on the ground’. Through a series of encounters with its operations this research looks to the ways in which practice and theory, in relation to the question of ecology, are becoming increasingly co-constituted.

With the availability of innumerable ‘intelligent’ building products and the dearth of inclusive evaluation tools, design teams are confronted with the quandary of choosing the apposite building control systems to suit the needs of a particular intelligent building project. The paucity of measures that represent the degree of system intelligence and indicate the desirable goal in intelligent building control systems design further inhibits the consumers from comparing numerous products from the viewpoint of intelligence. This thesis is organised respectively to develop models for facilitating the selection evaluation and the system intelligence analysis for the seven predominant building control systems in the intelligent building. To achieve these objectives, systematic research activities are conducted to first develop, test and refine the general conceptual models using consecutive surveys; then, to convert the developed conceptual frameworks to the practical models; and, finally, to evaluate the effectiveness of the practical models by means of expert validations.----- The findings of this study, on one hand, suggest that there are different sets of critical selection criteria (CSC) affecting the selection decision of the intelligent building control systems. Service life, and operating and maintenance costs are perceived as two common CSC. The survey results generally reflect that an ‘intelligent’ building control system does not necessarily need to be technologically advanced. Instead, it should be the one that can ensure efficiency and enhance user comfort and cost effectiveness. On the other hand, the findings of the research on system intelligence suggest that each building control system has a distinctive set of intelligence attributes and indicators. The research findings also indicate that operational benefits of the intelligent building exert a considerable degree of influence on the relative importance of intelligence indicators of the building control systems in the models. This research not only presents a systematic and structured approach to evaluate candidate building control systems against the CSC, but it also suggests a benchmark to measure the degree of intelligence of one control system candidate against another.

Cities are not merely inanimate objects. They are complex living environments, built over time by cultures and civilisations. This thesis argues that cities have a central place in human history and civilisation because they are imbued with meaning and meaningful activity. Thus, cities are inherently political spaces, and it may be reasonably expected that they will be important sites of social transformation in the postmodern era. In order to understand the relationship between urban space and political consciousness, this thesis traces several different interpretive paths within the marxist tradition. First, we examine the work of Henri Lefebvre, who argues for an understanding of urban space as socially produced. Next, the thesis looks at the contributions of Guy Debord, particularly at his understanding of the relation between time and the city. Both writers struggle to understand the urban in the context of the shift to what we now call postmodernity. Despite their many strengths, Debord and Lefebvre ultimately fail to theorise a social subject capable of resisting capitalist domination of the city. As a result, the thesis turns to a consideration of the work of Antonio Negri. Negri’s analysis of the fate of contemporary subjectivity has reinvigorated marxist critique with a return to the question of political change. His figure of the multitude takes leave of traditional marxism in challenging and productive ways, and helps us better understand the nature of subjectivity and resistance in a world of immaterial labour and virtuality. Nevertheless, this thesis argues that there is still work to be done before Negri’s work can be mapped out onto the contemporary metropolis.

This thesis explains how Oriented FAST and rotated BRIEF SLAM (ORB-SLAM), one of the best visual SLAM solutions, works indoor and evaluates the technique performance for three different cameras: monocular camera, stereo camera and RGB-D camera. Three experiments are designed to find the limitation of the algorithm. From the experiments, the RGB-D SLAM gives the most accurate result for the indoor environment. The monocular SLAM performs better than stereo SLAM on our platform due to limited computation power. It is expected that stereo SLAM provides better results by increasing the experimental platform computational power. The ORBSLAM results demonstrate the applicability of the approach for the autonomous navigation and future autonomous cars.

This thesis systematically examines vital socio-political factors which are impediments to democracy in Pakistan since 1947. The object is not to reach a single verdict on whether or not the whole regime can legitimately be called democratic, but to determine by empirical observation how democratic it is in its various parts. Democratic audit is a systematic, qualitative assessment of the performance of a regime's many parts against agreed democratic standards.

In recent years, there has been an increase in environmental awareness in the United States leading to steady growth in environmentally conscious consumerism. These changes have come in response to issues such as the energy crisis, climate change, exponential population growth, and rapid urbanization. This fact is further supported by environmental campaigns and the green movement. Looking to the future of green home marketing, understanding the green consumer behavior of Generation Z (GenZ) is important for environmental and business reasons. The purpose of this research is to better understand the perception of GenZ on Green Homes (GHs). The study uses the lenses of dual inheritance and normative motivation theory to explain the influence of benefits and norms related to environmentalism and sustainability on GenZ consumers’ green behavior. This study seeks to evaluate 1) GenZ’s preferences related to Green Home Features (GHFs), 3) the extent of the influence of certain barriers on the adoption of GHFs, and 3) the types of motivation (intrinsic, instrumental and non-normative) influencing GenZ towards green home consumerism. Data was collected using an online survey questionnaire exclusively at Purdue University during March – April of 2021 (IRB 2020-1414). One hundred sixteen GenZ participants responded to the survey.The findings show that these GenZ consumers prefer a certain type of GHFs over others. Additionally, based on descriptive tests of GHFs, energy-related features were the most prized features, while the least preferred was water-efficient features. Descriptive tests on barriers suggest that GenZ consumers perceive the lack of choice in selecting GHFs in their homes to be a top barrier, followed by a lack of information and the perceived effort to analyze GHFs. Inferential tests for the same indicated that GenZ consumers perceive these barriers differently. Lastly, for GenZ consumers, intrinsic and non-normative motivations significantly affect their willingness to buy GHs. The findings concur with previous studies on green consumer behavior, yet they provide a new benchmark for understanding GenZ consumer behavior on GHs and an updated view of what GHFs they prefer. This research can be used by home marketers and policy makers to study future home trends, attract more potential homeowners to GHs, and help create a sustainable environment for future generations.

Bioremediation is a prominent and novel technology among decontamination studies because of its economic practicability, enhanced proficiency, and environmental friendliness. The continuously deteriorating environment due to pollutants was taken care of by the use of various sustainable microbial processes. It is a process that uses microorganisms like bacteria and fungi, green plants, or their enzymes to restore the natural environment altered by contaminants to its native condition. Contaminant compounds are altered by microorganisms through reactions that come off as a part of their metabolic processes. Bioremediation technologies can be generally classified as in situ or ex situ. In situ bioremediation involves treating the pollutants at the site, while ex situ bioremediation involves the elimination of the pollutants to be treated elsewhere. This chapter deals with several aspects, such as the detailed description of bioremediation, factors of bioremediation, the role of microorganisms in bioremediation, different microbial processes and mechanisms involved in the remediation of contaminants by microorganisms, and types of bioremediation technologies such as bioventing, land farming, bioreactors, composting, bioaugmentation, biofiltration, and bio-stimulation.

The 5 Russian Arctic Seas have common features, but differ significantly from each other in the sea ice regime and navigation specifics. Navigation in the Arctic is a big challenge, especially during the winter season. However, it is necessary, due to limited natural resources elsewhere on Earth that may be easier for exploitation. Therefore sea ice is an important issue for future development. We foresee that the Arctic may become ice free in summer as a result of global warming and even light yachts will be able to pass through the Eastern Passage. There have been several such examples in the last years. But sea ice is an inherent feature of Arctic Seas in winter, it is permanently immanent for the Central Arctic Basin. That is why it is important to get appropriate knowledge about sea ice properties and operations in ice conditions. Four seas, the Kara, Laptev, East Siberian, and Chukchi have been examined in the book “Russian Arctic Seas. Navigation Condition and Accidents”, Marchenko, 2012 [1]. The book is devoted to the eastern sector of the Arctic, with a description of the seas and accidents caused by heavy ice conditions. The traditional physical-geographical characteristics, information about the navigation conditions and the main sea routes and reports on accidents that occurred in the 20th century have reviewed. An additional investigation has been performed for more recent accidents and for the Barents Sea. Considerable attention has been paid to problems associated with sea ice caused by the present development of the Arctic. Sea ice can significantly affect shipping, drilling, and the construction and operation of platforms and handling terminals. Sea ice is present in the main part of the east Arctic Sea most of the year. The Barents Sea, which is strongly influenced and warmed by the North Atlantic Current, has a natural environment that is dramatically different from those of the other Arctic seas. The main difficulties with the Barents Sea are produced by icing and storms and in the north icebergs. The ice jet is the most dangerous phenomenon in the main straits along the Northern Sea Route and in Chukchi Seas. The accidents in the Arctic Sea have been classified, described and connected with weather and ice conditions. Behaviour of the crew is taken into consideration. The following types of the ice-induced accidents are distinguished: forced drift, forced overwintering, shipwreck, and serious damage to the hull in which the crew, sometimes with the help of other crews, could still save the ship. The main reasons for shipwrecks and damages are hits of ice floes (often in rather calm ice conditions), ice nipping (compression) and drift. Such investigation is important for safety in the Arctic.
