The socio-economic value of holding a road cycling race around the lake in Bengbu Longzi Lake and its surrounding scenic areas is analyzed through theoretical research on the significance of the race, brand image, means of communication, route planning, and other aspects. The commercial and social value of holding the Tour de Lake for the Bengbu area is studied. Setting up the Tour de Lake will not only help to promote local visibility and the development of the leisure tourism industry but will also help to guide and promote the participation of the student population in the university city area of Longzi Lake in cycling.

Abstract Environmental pollution in cities is an increasingly popular issue tackled in research. One of the elements with a significant impact on the state of urban ecosystems is transport with its pressure on individual components of the environment. Sustainable urban transport is gaining prominence as a postulate expressed in cities’ strategic documents, constituting an element alleviating the negative effects of anthropopressure. In the light of the need to introduce innovative solutions for clean forms of transport, numerous papers indicate the bicycle as an answer to some of those problems. The article presents a review of literature referring to the socio-economic aspects of using the bicycle in cities as a means of transport for daily commuting. The analysis is based on publications on cyclist safety in road traffic, the perception of the bicycle as a means of transport in cities, and the introduction of innovative solutions, such as bicycle-sharing systems.

Full textAbstract:
Cycle tourists are increasingly prominent in the profile of world tourism and, in the light of the literature, it is essential, among other things, to examine more closely who they are, what their concerns and motivations are that generate the choice of a cycle tourism product, and, as a priority, the level of economic, social, and environmental impact they cause at destination. In this context, this literature review aims at identifying authors’ and publishers’ interest in cycle tourism, the positive and negative effects of this form of tourism on the economic environment (direct and indirect), as well as effects on the social environment (benefits and potential drawbacks for local communities, along with health benefits for practitioners) and, last but not least, the degree of vulnerability to economic crises generated by travel restrictions. The conclusions reported in this article, as they have been drawn from analyses and examples of best practice, based on natural and anthropogenic geographical conditions, will be prioritised as future research directions. The usefulness of this approach lies in the information with significant applied and novelty aspects, addressed to local, regional, and national authorities, cycling and cycle-tourism associations, and various private interested enterprises, with a view to promoting cycling for recreational purposes and implementing cycling/cycle-tourism infrastructure as a sustainable way of developing small towns and rural areas with tourism potential.

The purpose of this study was to determine the increase in tourist visits and the impact on business actors in improving the community's economy. The research approach used qualitative descriptive methods to determine the increase in regional tourism through the Tour de Flores cycling sporting event. From research, it is known that with the implementation of the Tour de Flores, tourism in Ende Regency has increased from the previous year. The Tour de Flores cycling sport can indirectly achieve its goals, one of which is to improve people's living standards and improve public facilities and facilities. However, it cannot be denied that this increase has not been fully felt by the people of Flores, especially those in Ende Regency. The problems of the government and related institutions must be carried out optimally through increasing human resources, the economy, sports infrastructure and regional tourism innovation prioritizing HR, economic and other aspects.

Usually, the figures and facts used to analyze cycling mobility in the urban environment, are hardly based in references to infrastructures as a factor that facilitates / hinders that mobility. Convinced of the need to consider other influential variables, we address from the CICLA project the general objective of knowing mobility in urban areas of Andalusia. More specifically we are committed to knowing which are the main social discourses and practices around the use of the bicycle, within the need to incorporate social, economic, political and cultural aspects usually separated from the analysis. Based on a qualitative methodology and a holistic approach, the results of this research shed light on some of these aspects, providing some conclusions and reflections of interest for the promotion of the bicycle as a means of transport in our cities.

Full textAbstract:
Mobility is one of the most important and challenging aspects that influence climate change, air quality, and especially the quality of citizens’ lives. Therefore, creating sustainable transport solutions makes way for different modes of transport such as the bicycle, which is continuously gaining more supporters, due to the health, economic, and environmental benefits that it provides. However, cyclists are facing several barriers (e.g., lack of infrastructure), a fact that keeps away commuters from using a bicycle for their daily trips. Investigating the factors that reflect on the commuters’ intention to use a bicycle is a sine qua non for the promotion of sustainable mobility. Therefore, the objective of this paper is the investigation of the factors that prevent residents with low experience or with no cultural/lifestyle background in regards to cycling from cycling. The case study of the city of Larnaca (Cyprus) is deployed by exploring the socio-demographic and trip characteristics of the city’s residents and their relation with the intention to cycle. A two-step approach is developed, namely Explanatory Factor Analysis (EFA) and Structural Equation Modeling (SEM). Despite the promotion of cycling that education is attempting to do (successfully), other factors (such as age, distance, and time) appear to prevent Larnaca’s residents from cycling. Among the actions that local authorities should undertake is that of safety prevention of the vulnerable users of the road network. This group includes elderly people, who need major encouraging interventions by local policymakers and stakeholders.

Full textAbstract:
For decades, transportation has been considered as a link to all aspects of life worldwide. In this case, the world’s natural environment, social well-being and economic development all usually depend on transportation systems. In most cases, safe, clean, sustainable and equitable transport systems help countries, especially in cities and urban centers, to thrive. However, a wide range of research shows that transportation systems in most of the cities and urban areas are unsustainable. In fact, some of these transportation systems are considered to be a threat to the environmental, social and economical aspects of future generations. In this perspective, therefore, changing such trends in transportation requires the collaboration of various stakeholders at regional, national and international levels. In this paper, therefore, a wide range of definitions of sustainable transport are discussed. More so, some of the aspects of smart transport for modern cities such as cycling and the role of women in sustainable transport were explored. With the aim of getting to the core of the subject, cases of women in bicycle transport, especially in the Netherlands and Germany compared to Kenya and Uganda are equally elucidated. Although not fully outlined, the idea of smart cities and sustainable transport have heterogeneous characteristics globally as discussed herein.

Kyoto Protocol states that developed countries have the responsibility to reduce the amount of greenhouse gas emissions. It, also, suggests that developed countries take measures to enhance carbon sink. Therefore, every country pays more attention on the research of global carbon cycle. China, a developing country with a fast economic increasing rate, has urgent need of related data and information so as to adjust its national development plan and negotiate with other countries. Remote sensing is one of the most important technologies and data sources for large-scale carbon-related researches including terrestrial ecosystem carbon cycling law, carbon sink/source pattern and sink enhancement technology. This paper introduces recent applications of remote sensing technology to the following aspects in China: monitoring land cover, simulating carbon flux, spatial distribution of carbon sink and carbon sink enhancement measures.

This thematic issue focuses on important but understudied connections between cities and climate impacts of long-distance travel. While urbanization and urban density have climate change mitigation potential in short-distance travel (e.g., by reducing car use and supporting public transportation, walking, and cycling), they have been associated with a higher level of emissions from flights. This highlights the role that city-regions could potentially play in reducing climate impacts of aviation. At the same time, the development of airports and flight connections has been an important driver of economic growth at regional scale and a factor contributing to global competitiveness of city-regions. This thematic issue includes seven interesting articles focusing on different aspects of the theme, all of which are briefly presented in this editorial. We also lay down some suggestions for future research directions based on the findings presented in this thematic issue.

Full textAbstract:
Gully erosion causes severe damage to crops and infrastructures and affects the provision of ecosystem services worldwide. To assess the potential of gully control measures to protect ecosystem services and assess the conditions required for their large-scale implementation, this paper critically evaluates a range of gully control measures documented in the World Overview of Conservation Approaches and Technologies (WOCAT). Environmental and socio-economic impacts of technologies are assessed, as well as the implications for ecosystem services, costs and benefits of implementation, and stakeholder’s perception. It is demonstrated how gully control measures provide notable on-site and off-site benefits for socio-economic, cultural, ecological, and production goals, and to protect crucial ecosystem services. Control measures particularly contribute to soil and water conservation and to regulating ecosystem services by controlling soil erosion, water cycling, and natural hazards. Most effective control measures consist of combined vegetative and structural measures and of catchment wide interventions. While implementation of gully control can initially be expensive, on the long term, the cost-benefit ratio is usually positive. Moreover, the results emphasize the importance of evaluating control measures considering monetary aspects and all ecosystem services they provide. Nevertheless, individual farmers can often not afford the implementation and maintenance costs due to barriers for implementation and therefore require sustained institutional support.

Transport systems are essential to trade, globalisation, communication and other forms of interaction between people and societies (Banister, 2013). Yet they can also have negative impacts including decreased quality of life or health impacts arising from pollutants, environmental damage including climate change and a range of wider socio-economic effects (Glanz et al., 1990). Given that most car journeys are short however (57% of UK trips are under five miles), there is particular potential for active travel (i.e. walking and cycling) to both reduce the environmental externalities of modern transport systems and stimulate improved quality of life and societal wellbeing (Banister, 2013; Martin et al., 2014). Unfortunately, there is a paucity of robust evidence that examines how infrastructural interventions (i.e. those aimed at making the physical environment more conducive to active travel) actually impact on active travel levels in specific communities. In addition, there is very limited evidence of the wider effects that such interventions have on wellbeing and levels of happiness overtime. This thesis details mixed-method research undertaken in Cardiff, UK, during 2011/2012, which examined the impacts of a new piece of infrastructure - the Pont-y-Werin walking and cycling bridge - on the local community's levels of active travel and subjective wellbeing. It provides insights into the nature of constraints preventing travel behaviour change from taking place, and - through the use of the novel, 'Day Reconstruction Method' - into the consequences that different modes of travel can have for travel and wellbeing, including on moment-to-moment moods and emotions. Overall by contextualising and measuring and evaluating wellbeing, the research suggests that people experience less pleasant emotions during travel than when undertaking everyday activities, and also that for certain modes there is a decrease in happiness before and after travel compared to everyday activities. Additionally greater monitoring, evaluation and promotion of combined hard and soft measures - focusing on travel behaviour change - is needed alongside providing travellers with accessible information on the wellbeing impacts of different modes (Elvik, 2009).

AbstractTropical cyclone (TC) risk assessments are critical for disaster preparedness and response. Alongside hazard and exposure, accurate TC risk assessment requires understanding the vulnerability of populations and assets. In this chapter, we examine multiple methods that have been used to assess and quantify TC vulnerability with a focus on open-source methods. We separately discuss structural, economic, and social (or demographic) vulnerability approaches. Structural vulnerability assesses the susceptibility of buildings to be affected by their exposure to hazards; in this section, we provide a detailed overview of how FEMA’s Hazus model quantifies damages by utilizing engineering principles. Economic vulnerability employs regression analysis to relate wind speeds to damages; this discussion explores typical functional forms used to represent vulnerability in such analysis and efforts to constrain parameters in these functions. Finally, social approaches use demographic data to characterize the varying susceptibility of populations to TC risk; we provide some representative examples of this methodology. We conclude with a comparative discussion of these three classes of methods, suggest directions for future work, and ask whether the different approaches can be combined to yield a more holistic view of both the human and structural aspects of TC vulnerability.

Full textAbstract:
AbstractA great deal of the contemporary discourse around circularity revolves around waste—the elimination of waste (and wastelands) through recycling, renewing and reuse (3Rs). In line with industrial ecological thinking, the discourse often focuses on resource efficiency and the shift toward renewables. The reconstitution of numerous previous ecologies is at most a byproduct of the deliberate design of today’s cyclic systems. Individual projects are often heralded for their innovative aspects (both high- and low-tech) and the concept has become popularly embraced in much of the Western world. Nevertheless, contemporary spatial circularity practices appear often to be detached from their particular socio-cultural and landscape ecologies. There is an emphasis on performative aspects and far too often a series of normative tools create cookie-cutter solutions that disregard locational assets—spatial as well as socio-cultural. The re-prefix is evident for developed economies and geographies, but not as obvious in the context of rapidly transforming and newly urbanizing territories. At the same time, the notion of circularity has been deeply embedded in indigenous, pre-modern and non-Western worldviews and strongly mirrored in historic constellations of urban, rural and territorial development. This contribution focuses on two contexts, Flanders in Belgium and the rural highlands, the Mekong Delta and Ho Chi Minh City in Vietnam, which reveal that in spite of the near-universal prevalence of the Western development paradigm, there are fundamentally different notions of circularity in history and regarding present-day urbanization. Historically, in both contexts, the city and its larger territory formed a social, economic and ecological unity. There was a focus is on the interdependent development of notions of circularity in the ever-evolving relations of landscape, infrastructure and urbanization. In the development of contemporary circularity, there are clear insights that can be drawn from the deep understandings of historic interdependencies and the particular mechanisms and typologies utilized. The research questions addressed are in line with territorial ecology’s call to incorporate socio-cultural and spatial dimensions when trying to understand how territorial metabolisms function (Barles, Revue D’économie Régionale and Urbaine:819–836, 2017). They are as follows: how can case studies from two seemingly disparate regions in the world inform the present-day wave of homogenized research on circularity? How can specific socio-cultural contexts, through their historical trajectories, nuance the discourse and even give insights with regard to broadened and contextualized understandings of circularity? The case studies firstly focus on past site-specific cyclic interplays between landscape, infrastructure and urbanization and their gradual dissolution into linearity. Secondly, the case studies explicitly focus on multi-year design research projects by OSA (Research Urbanism and Architecture, KU Leuven), which underscore new relations of landscape, infrastructure and urbanization and emphasize the resourcefulness of the territory itself. The design research has been elaborated in collaboration with relevant stakeholders and experts and at the request of governmental agencies.

The word environmental sustainability of late has been used as catch word for illustrating the climate change and subsequent sequential impact of various aspects of environmental landscape that include soil management, gaseous exchange, nutrient cycling, carbon emission, rainfall etc., Interpretation of environmental changes are interpreted based on very few trends which need not necessarily cause short term or long term impacts. The impact assessment of a region fundamentally depends on region specific history of habitat management, human interference, agricultural practices, Economic livelihood activities which depend on available natural resources and seasonality of intensity of activities. In the present study efforts are made to indentify the major NTFP based livelihood economic activities and relate the habitat management aspects along with commercial invasion that became detrimental to environmental threshold to call for sustainability alarm. The livelihoods in various developing economies have different environmental impacts. Such assessment of economic activities have any real environmentally detrimental consequences or is it being essentially over emphasizing to create such fears have been analyzed.

In the last two decades the term sustainable supply chain management (SSCM) has become quite popular. Organizations are working on sustainability of their supply chain (SC). Sustainability covers environmental, social, and economic aspects of different supply chain management activities. Organizations are continuously working in the direction of making their processes and product green. On the environmental front, use of renewable source of energy, reducing waste of energy, reducing carbon footprints is important. Simultaneously, reuse of products, re-cycling, and following environmental standards while disposing off is also recommended. In this chapter, the author has identified 13 issues and challenges of SSCM from literature review and expert opinion. Simultaneously, the author has also identified nine new technologies of modern time used in industries. Further, the author has tried to analyze the linkage between the challenges of sustainability and intelligent technologies by Jaccard's similarity coefficient methodology.

Imprensa da Universidade de Coimbra, 2022. http://dx.doi.org/10.14195/978-989-26-2298-9_230.
Full textAbstract:
Forest management operations adequately integrated in the forestry value-chain are the gold standard in wildfire prevention. However, these operations generate considerable amounts of residual forest biomass (RFB) that cannot be legally disposed in land and further require suitable management. Residual biomass also includes highly flammable plants existing in the Portuguese forest such as gorse, broom, giant reed and acacia. Quite often wildfires in Portugal are linked with spreading of this residual biomass that promotes fuel accumulation. Besides deleterious impacts on rural and forestry economy, wildfires are also a driver for desertification and soil degradation. Alternative uses for this residual biomass to promote its valorisation and enable proper models of management of forest areas are needed, thus providing economic and environmental benefits towards decreasing of the fuel load. Though this biomass has reasonable carbon content and heating value, they also present inorganic composition (e.g. Na, K, Cl) that promotes operating problems in thermochemical conversion processes as combustion and gasification for useful energy production because of ash related problems (e.g., sintering/fouling), thus restricting their use in such applications. As such, biochar production by pyrolysis is a potential alternative to generate added-value. During pyrolysis the volatile matter of biomass is released to the gaseous phase, resulting a solid product, biochar, which is carbon-rich and contains most of the inorganics (nutrients) of the raw biomass. Exposure of biomass inorganics as free ashes is prevented in this process, and hence pyrolysis mitigates their negative effects. Nonetheless, the efficient pyrolysis of these types of biomass requires development of novel solutions optimized for energy and environmental performance. Enhancing of the energetic sustainability of the process and minimizing of the environmental impacts associated to the emission of gaseous pollutants are aspects of major relevance. Additionally, the biochar quality depends on biomass type, technology and operating conditions used. The BioValChar project (https://biovalchar.web.ua.pt/en/) seeks to answer these challenges related to valorisation of low-quality residual biomass through production of biochar by pyrolysis, which can return back to forest and rural soils. This approach will provide both carbon/nutrient cycling and synergies within forestry management, wildfire prevention, improvement of soil quality and rural development, under the circular economy principle. The research focus valorisation of residual forest biomass in full-control pyrolytic batch and continuous (auger-type reactor) processes, and testing of the resulting biochar performance as soil amendment. Moreover, a prototype of an integrated mobile unit for auto-thermal and continuous biochar production by pyrolysis of biomass is also being developed, by using the pyrolysis gases to provide the energetic needs of the process. Here we present the project overview, as well as some preliminary results on pyrolytic valorisation of one selected biomass (acacia) into biochar through distinct operating modes and conditions.

Full textAbstract:
This chapter is a conceptual contribution to this book on data mining applications upholding ethical issues related to two extremely important aspects of the Bangladeshi population: the early warning system and the disaster management system. The chapter tries to provide a few conceptual ideas to introduce ethical data mining application in these systems to support the agencies that are involved for an improved, efficient, and transparent support system in the country, especially across the Bay of Bengal. Resembling a triangular shape (deltaic), a major portion of the bay touches the southern portion of Bangladesh. Sediments from rivers have made the bay a shallow sea. Due to its shallowness and shape, monsoon rains and cyclone storms become destructive, causing great loss of life along the southern part of the country. Moreover, the three mighty rivers (Padma, Jamuna, and Meghna) form one of the largest river systems in the world. They have a large number of distributaries and tributaries, which cause a major portion of the country to be inundated by monsoon rain. In addition, being the lowest landing zone of the Himalayan water, Bangladesh becomes victim to floods almost every year. Loss of lives, destruction of properties, suffering of numerous people and hampering of economic development have become part and parcel of Bangladeshi communities. This chapter suggests that the newly emerged data mining techniques can be introduced to collect, synthesize, analyze, archive, disseminate, and even make future forecasts forming a reliable early warning system across the Bay of Bengal.

The public space encourages social exchange, develops and maintains social groups and allows the exchange of public messages. When the public space and public life are not supported in the community, there is no one to communicate with, people become isolated, less inclined to help or support each other. Public space is the scene of public life that promotes a sense of community, sense of place, human connection and communication as well as dependence sensation. High-quality and well-managed public space is a benefit to the city's economy, creating shelter from the car-centred life and move to a more natural environment as well as significant urban land use. Therefore, in recent times, in order to establish the right conditions in cities for different human needs, great attention is paid not only to the development of physical infrastructure, but also to other aspects that will help to create sustainable balance of social, economic and environmental aspects. One of the quality of life in the city return ways is the release of urban spaces for pedestrians. Until these days the pedestrian zones are extended little by little, resulting in disposal of the car parking-lots and improved cycling and other transport facilities. Sustainable use of urban pedestrian zones would provide economic, social, environmental and cultural benefits only if these aspects are combined with each other. The aim of the article is to distinguish and critically analyse (on the basis of a literature review) factors influencing the functionality and sustainable development of pedestrian streets. Article object – cities pedestrian street. The study was conducted using scientific publishing content analysis and synthesis techniques. This article is an overview.

The today’s energy market requires highly efficient power plants under flexible operating conditions.

The need for highly efficient steam turbines is driven by CO2 reduction programs and depletion of fossil resources. Increased efficiency requires higher steam temperatures up to 630°C in today’s units or even more for future steam power plants. The gap between material properties in the hot and cold running parts of a steam turbine rotor is widened by increased live steam temperatures and the increased demand for flexibility. These technical challenges are accompanied by economic aspects, i.e. the market requirements have to be met at reasonable costs. The welding of steam turbine rotors is one measure to balance required material properties and economical solutions. The rotor is a core component of the steam turbine and its long-term integrity is a key factor for reliable and safe operation of the power plant. An important aspect of weld quality is the determination of permissible size of weld imperfections assessed by fracture mechanics methods. The integrity of rotor weld joints is assured by ultrasonic inspection after the final post weld heat treatment with respect to fracture mechanics allowable flaw sizes. This procedure usually does not take credit from the quality measures applied during monitoring of the welding process. This paper provides an overview of an holistic design approach for steam turbine rotor weld joints comprising the welding process and its improved online monitoring, non-destructive evaluation, material technology, and its fracture mechanics assessment. The corresponding quality measures and their interaction with fracture mechanics design of the weld joint are described. The application of this concept allows to exploit the potentials of weld joints and to assure a safe turbine operation over life time.

The article presents the results of the theoretical analysis of the main aspects of sports training in cyclic sports. To effectively solve the problem of training in cyclical sports, it is necessary to study the laws of the reaction of the body of athletes, including the processes of fatigue and recovery in response to the physical exertion of various directions. It is very important to individualize the training process, taking into account the functional state and reserve adaptive capabilities of the body. The authors identify such reasons that influence the development of cyclical sports as socio-economic and political transformations that are constantly taking place in Russia; demographic changes caused by the decline in the population of Russia due to the collapse of the Soviet Union; structural and organizational reasons that suggest the existence of an outdated system for training highly qualified athletes, the lack of modern centers and bases for Olympic training, an effective management system for Olympic training in General, and a targeted policy for training coaches and sports and medical personnel. The technological reasons that arose as a result of a sharp reduction in targeted research in all branches of sports science and an archaic mechanism for the development and implementation of effective innovative technologies are revealed. There is a significant lag in the medical and biological provision of training for Olympic athletes, etc. The analysis showed that the lag in the structural, organizational, and technological blocks of Olympic training is caused by a decrease in the effectiveness of scientific research.

Full textAbstract:
Abstract Suction embedded plate anchors (SEPLAs) are an economic solution for the mooring system of a floating production platform and have been deployed both in the Gulf of Mexico (GoM) and around the globe with excellent field performance records. The design of SEPLAs has gradually matured over the past two decades for conventional SEPLAs, but debates continue both in the industry and academia, e.g., on the function of the flap and the required keying. These design aspects become more critical for permanent mooring systems in the GoM where the anchors have to resist large mooring tensions from hurricanes, and balancing safety and economy is a challenge. Thus, the objective of this paper is to present design considerations for large-size SEPLAs for permanent mooring systems in the GoM. The design considerations in this paper include the embedment loss, the functions of the flap and keying, cyclic loading, sustained loading, keying disturbance, and out-of-plane loading. Recommendations are provided to advance the design of large-size SEPLAs, and more specific guidance is offered relative to the ambiguous requirements currently in the industry guidelines.

Cycle to Cycle variations in SI engines have increased our attention as reducing these CBC fluctuations will lead to better drivability, increased power output, better fuel economy, reduced emissions. As auto industry is growing at an alarming rate, numbers of users of automobiles are increasing day by day & strict emission standards have led people to think about the ways of increasing power with the same input. In this aspect evaluating the reasons for CBC variations has become the urgent need. In the present work a C-program has been written to simulate the same and pressure crank angle diagrams and MFB-crank angle diagrams for three different models & three different burn rates. The results are plotted & analyzed so that the best operating conditions are developed. The effects of Equivalence ratio, speed, throttle etc are studied.

A great number of research groups and manufacturers are involved in the development of micro energy conversion systems. In particular the analysis is focused on heat exchangers and it deals with several aspects, such as the physical principles regulating heat and mass transfer in microchannels and the production process itself. Many benefits are expected from the on going process, such as improvement of the heat exchange, improved performances with partial loads, the opportunity to use innovative materials. On the other hand this process, started within the industrial sphere, could be boosted by the necessity of less costly production processes, through the cost reduction for materials and power, and through economy of scale. This paper aims to confirm if the actual trend of miniaturisation drives to effective benefits in terms of energy saving. For this purpose various aspects influencing the efficiency of the energy conversion devices are considered. For the efficiency of the global system (user, device and connection), special attention is paid to find the optimal trade off between the advantages due to the reductions of ducting and cycling losses and the disadvantages due to the negative influence of the size on the system’s performance.

Full textAbstract:
The configuration of urban areas is the result of a cyclic relationship between land use and transportation system: the changes in transportation system arrangements influence the localisation of residence and economic activities, as well as the changes in land use affect transportation system characteristics. In this context, by operating on land use, travel demand can be shift from the individual transportation modes to transit systems. In the literature, many conceptual models were proposed to describe the complex relationship between land use and travel behaviour. In addition to spatial variation, the study of travel demand shows the categorical variation of variables. This work aims to analyse the influence of the categorical variation of variables impacting on transit use. An ordered probit model is proposed for evaluating how transit use depends on variables related to socio-economic characteristics of population, territorial features, accessibility, and transportation system. The study case is Madrid metro network (Spain). The results show a strong influence of characteristics of population and land use variables on daily trips made using metro system and highlighted the aspects that mainly impact on the choice to travel by metro, providing useful suggestions for shifting people from individual transportation mode to transit systems.DOI: http://dx.doi.org/10.4995/CIT2016.2016.3205

Full textAbstract:
Abstract Well integrity is one of the most critical elements for extending the producible life of a well. A healthy well enables optimization of productivity, enhanced oil recovery, trial tests of new technologies, and much more. Factors such as external corrosive aquifers, internal corrosion, corrosive hydrocarbons, cement bond damage, solids and sand production, and others are considered the main integrity dangers worldwide. When well integrity is affected, not only economic risks but also risks to health, environment and safety are probable. Well integrity is an objective achieved by optimum design and construction of the well after studying and assessing all possible hazards; effective monitoring of the well behavior while it's under production; and timely intervention when an integrity problem is detected. Evaluating all the aspects of well integrity during well operation is crucial. Cyclic surveillance is important to be followed, including wellhead pressures/annuli surveys, temperature surveys, corrosion logs, wellbore clearance, and well fluid samples, among other activities. With the help of smart and integrated systems, production engineers can have much better control over well integrity and be proactive in making timely decisions prior to any unforeseen events. The smart system keeps the well surveillance records, risk-rank the wells, and sets KPIs to tackle necessary actions wherever applicable. The developed system immediately triggers any threat on well integrity when it occurs.

In Qatar University Annual Research Forum & Exhibition. Qatar University Press, 2021. http://dx.doi.org/10.29117/quarfe.2021.0019.
Full textAbstract:
The Exclusive Economic Zone (EEZ) of Qatar is affected by extreme dust and extensive industrialization, making it an ideal location to examine influences of coastal processes on biological activity, which greatly affects marine biogeochemical cycling. In this study, the influence of dust on the trace element composition of plankton and how distance from shore effects elemental concentrations in marine plankton was investigated. Samples were collected using net tows with mesh sizes of 50 (bulkplankton) and 200 (zooplankton) mm size-fractions in 2012 and 2014 to examine temporal and spatial variabilities. The samples were strong acid digested and analyzed using ICP-OES. Trace metal clean techniques were used. The biogenic concentrations of trace metals were determined by correcting the bulk analyses for the lithogenic contribution using aluminum content of Qatari dust as a lithogenic tracer. The relative trace metal composition of plankton from EEZ of Qatar is Fe > Zn ≈ Cu > V ≈ Ni ≈ Cr ≈ As ≈ Mo > Cd ≈ Co. Small and large size planktonic compositions were similar, except for Ba, Mn, Pb, Mo which were higher in zooplankton than bulkplankton. It was not clear if the variability was due to differences in biology, proximity to the coast or interannual effects. The geochemical and statistical analysis suggested that the concentrations of Al, Fe, Cr, Co, Mn, Ni, Pb, Li in net-tow plankton samples were mostly of lithogenic (dust) and Cd, Cu, Mo, Zn, Ca are most likely of biogenic/anthropogenic origin. The excess concentrations relative to average dust from Qatar for most elements (except Cd) decreased with distance from shore. This may be due to contamination or uncertainties with the lithogenic correction or due to our sampling locations in a marginal sea, dominated by dust input. This is an aspect of this study that warrants more research.
