Material Management in Planning and Construction of Ancient Buildings
Authors: Li Dinghai
Published: January 2021

According to the unique style and historical significance, Chinese ancient architecture which has a long history, plays an important role in world architecture. Most of Chinese ancient architecture uses wooden frame as a load-bearing system, however, a unique combination of components has emerged in its development. Due to the well-preserved ancient buildings and a long historical and cultural background of Qijiang ancient town, the paper takes the Qijiang ancient town as an example through field measurement and investigation. The composition of the external environment of the building, architectural characteristics and building monomer composition were analyzed and studied. The unique architectural art charm of Qijiang ancient town was showed. Moreover, the delimitation of the protection scope mainly includes the scope of protected areas and the scope of the construction control zone. Among them, the protected areas are generally divided into key protected areas and general protected areas; the construction control zones are generally divided into Type I of construction control zone and Type II of construction control zones. Ancient buildings are the most existing heritage types in China and are an important part of the immovable cultural relics in China. The group layout of ancient buildings is an important feature in the layout of ancient buildings in China, which is conducive to the realization of the overall protection of heritage.
Research on Planning and Management of Large-Scale Sports Venues in Chinese Cities
Authors: Chen Yan
Published: January 2021

To improve the operational management benefits of large-scale sports venues, the literature data method, questionnaire survey method, and comparative analysis method were used to study the planning and management of large-scale sports stadiums in China. From the macro external environment, the micro external environment and the internal management of the venue, the opportunities and challenges of China's large stadiums were analyzed. Corresponding countermeasures to improve the efficiency of venue operation management were proposed. The results show that the proportion of business structure of large-scale sports stadiums in China was unreasonable, and the ontology management was in a polarized development trend. The venue utilization rate was generally low. In addition, the operational management benefits of large-scale sports stadiums in China were affected by the micro-external environment and the internal conditions of the venues. Therefore, this research has important reference significance for the operation and management of stadiums.
Configuration of Public Sports Venues in China's Counties Under the Background of Urbanization
Authors: Li Li
Published: January 2021

To promote the effective allocation of public sports venues in the county and promote the construction of new urbanization, the allocation of public stadiums in the county was studied under the background of new urbanization. Interviews and literature research methods were adopted. The differences between the new urbanization and the traditional urbanization of the county's public stadiums were discussed. Under the background of new urbanization, the status quo of the allocation of public stadiums in China's counties was studied. Under the background of new urbanization, the problems and influencing factors of the allocation of public stadiums in China's counties were analyzed. The corresponding proposal was put forward. The results showed that the number of county venues in China was greatly improved, but the total amount was still insufficient. The configuration structure was improved, but the structural imbalance was still significant. The way of configuration was innovative, but the government dominated the main position. The configuration policy was constantly improving. The legalization was not perfect. Therefore, the balance between supply and demand, the balance of urban and rural settings, the optimization of public sports venues, and the establishment of public stadiums under new urbanization are important. This will help to promote the study of the allocation of public sports venues in China's counties under the background of new urbanization.

Authors: Jiao MA , Guoyuan WU
Published: January 2021

The paper is aimed to avoid the situation that historical relics are encroached, isolated and fragmented because of cities in the rapid urban process. Taking the environment around the Qinglong Temple in Xi'an city as an example and based on the characteristics of urban patterns in the history, this paper explores the spatial connection relationship between historical relics and surrounding villages as well as the connection between metro traffic and commercial bodies. At the end of the paper, the improvement strategy is put forward, namely the design concepts of “stepwise style” and “landscape style”, which can be achieved by the demand of ecological restoration and the relationship between urban axis. To be noted, the research shows, by restructuring new connection space, the city can promote the urban memory to be restored, the urban appearance to be reshaped, and the urban patterns in the history to be respected and displayed.

Strengthening Community Initiatives, Building Partnerships Opp-Rti Sanitation and Housing Programme, Pakistan
Authors: Rahman Perween
Published: January 2021

The Orangi Pilot Project-Research and Training Institute's (OPP-RTI) work is based on the observation that poor people everywhere when faced by problems do not sit idle, but take initiatives, from lobbying to self help, be it for housing, infrastructure, education, security, health or employment. Some technical and organisational guidance and in some cases, credit is needed to strengthen people's work leading to confidence building and a process of partnerships in development. What began from supporting self-help sewers and housing in the informal settlement of Orangi in Karachi has now extended to many cities and sectors, influencing government policy.

THE HOME HOUSE PROJECT; THE FUTURE OF AFFORDABLE HOUSING
Traditional Environments, Culture and Preservation
Authors: Rapoport Amos
Published: January 2021

This paper is conceptual and theoretical and should be seen as an extended hypothesis. I begin by pointing out that reasons for seeking to preserve traditional environments are rarely explicit (although they should be), however some of the reasons can be inferred. One of these is ‘culture,’1 in terms of cultural identity and continuity. I then argue that ‘culture’ can also be seen as possibly the major obstacle to preservation.

I restate my position that ‘culture’ is both too broad and too abstract to be usable, and apply a specific approach which I have used for other aspects of Environment-Behaviour Relations. I suggest that it is also useful in this connection, so that the method becomes even more general. This involves dismantling ‘culture’ into a set of more concrete expressions and more specific components. These, and changes in them are used to understand the problem with trying to preserve traditional environments. These problems result from disagreements among a variety of groups about environments, especially about the components of environmental quality, which I describe by means of profiles. I then discuss some of the interactions among the different aspects of culture identified and some selected components of environmental quality.

I conclude by discussing a different form of preservation – of the principles and lessons present in traditional environments, rather than the environments themselves. These, it is suggested, may be of use in designing better new environments. I also suggest that the approach used not only begins to explain the issues and problems, but may also begin to suggest solutions.
Transformation of Traditional Environments: The Spatial Geography of Culture and Built-Form in Sri Lanka
Authors: Dayaratne Ranjith
Published: January 2021

This paper examines the transformations that have been taking place in culture and built form in Sri Lanka and their spatial geography mooted by the open economic policies introduced in the 1970 s and the subsequent developments. It analyses the major facets of the dominant Sinhalese culture having located them within the sacred and profane realms, nature and its social make up. Major characteristics of the traditional culture and built-form are identified and through a longitudinal study of six case studies around the southern region, the study elucidates the major transformations and the social and societal forces behind them. The paper proposes three models for understanding such cultural transformations; Conventional-Sri Lankan, Transitional-Sri Lankan, and Euro-Sri Lankan, the forms of which could also be used in other similar situations.

Published: January 2021

This article aims to explore the changes and continuity in housing patterns of Turkish society comparing traditional and contemporary usage. In this context, the spatial and social structures of housing patterns are studied comparatively from an historical perspective. The article is based on research projects carried out by the author that aimed to identify the effects of socio-cultural and psychological factors on the spatial formation, meaning and use of domestic space in different types of Turkish dwellings. Examples chosen from a number of case studies in different housing patterns are mainly those of the Middle Asian Tent, the Traditional Turkish House and Squatter Housing ‘Gecekondu’. The article consists of six sections. In the first two, the aim and the general concept of the paper are defined, the research field is explained and the problem is specified. In the third section, the formation of spatial setting in different housing pattern of Turkish settlers will be analysed by comparing the tent, traditional house and squatter house. The fourth section focuses on related theoretical concepts in environmental behavioural studies with the conceptual model of culture and space interaction system in terms of meaning and use of home space. In the last two sections, the field study is presented and the article builds on the findings of the case studies to offer some proposals for new design principles.

Sustainable Tourism As An Alternative to Mass Tourism Developments of Bafra, North Cyprus
Authors: Türker Özlem Olgaç , Dinçyürek Özgür
Published: January 2021

Today, there is a growing tendency towards tourism based economical activities. However, the impact of tourism particularly in the less developed countries can be very destructive in terms of the environment that is also an attraction point for tourists. It is widely acknowledged that tourists prefer to experience the natural environment, the social and cultural life, the historical heritage of the region they are visiting. Hence it is obligatory to answer these needs in a responsive tourism development process. When sustainable tourism is mentioned it includes conservation of natural and architectural environment, as well as the cultural identity while providing economical benefits. In this respect, sustainability of these particular natural, cultural and architectural environments is a crucial issue. The integration of tourism with the local environment and local community is another important factor in successful planning. In light of this discourse, the ongoing tourism developments in Bafra region in the north of Cyprus are standing at a very challenging position for decision makers in terms of balancing the impacts of tourism on these resources. Bafra's coastline is recently becoming a new center for mass tourism by its increasing number of hotels, holiday villages, recreation areas, etc. This study proposes sustainable tourism planning for a unique traditional rural settlement-Bafra Village- which is located in close vicinity of this heart of tourism. The continuity by conversion of existing traditional housing stock of Bafra village for tourism purposes is critically discussed in order to minimize the potential threats of increasing tourism demands.
Prevention of Hiv/Aids-Associated Opportunistic Infections Through Housing and Municipal Services
Authors: Tomlinson Richard
Published: January 2021

The background to this paper is the increasing interest in the relationship between housing and municipal services and HIV/AIDS. The purpose of this paper is to clarify what, precisely, one has in mind when thinking that housing and municipal services might prevent HIV infection and associated opportunistic infections. The focus is not on the socioeconomic dimensions but on the modes of transmission associated with specific opportunistic infections. That is, the paper first disputes the relevance of housing and services to HIV prevention, but then demonstrates that housing and municipal services are important for (a) the prevention of certain opportunistic infections to which people affected by HIV/AIDS are particularly vulnerable, and (b) for the provision of home-based care.

In addition to the medical focus of the paper, there is attention to the empirical backdrop on the relation between housing, municipal services and HIV/AIDS, analysing survey findings regarding among whom and where HIV prevalence is highest, and projections regarding the extent of HIV infections and AIDS based on the World Health Organization clinical staging system. Using Johannesburg as a case study, it is demonstrated that the number of persons having AIDS is smaller than one might expect and also that the number is already declining, which has implications for the provision of home-based care. However, it is also shown that the number of households that lost one or several members is increasing rapidly. In this context, labour force surveys are employed to identify the impacts on specific categories of households. At this stage, a defining unknown is the scale, nature and location of these reconstituted households and what this means for housing policy.

Finally, a feature of the research was the extent to which medical practitioners viewed housing as a quixotic sideline within the broader struggle for HIV prevention and the provision of treatment. In sum, the paper provides an argument for incorporating housing and municipal services into both HIV and AIDS prevention and treatment programmes.
Traditional European Squares in Contemporary Urbanism: Dubrovnik's Medieval Squares
Authors: Haas Tigran
Published: January 2021

Buildings alone do not matter, it is only the ensemble of streets, squares, and buildings and the way they fit together that comprises the true principles of good urbanism and place making. One of the main rules of good urban design is the quality of the public space. This paper analyzes the importance of creating & maintaining a true public square in contemporary urban condition, as one of the built environments' pillars for sustaining social and cultural identity.

Criticism has been posed towards the (neo) romanticizing the importance of European squares (as some critics would call it “Postcard Squares”) in everyday life and contemporary town planning. Movements such as New Urbanism, which promote good urban design have not put squares that high on their urban design agendas. Also the usage of the historic European city's public realm model - the square - as the important ingredient for all urban places has not been forthcoming. To investigate this phenomena, and facilitate the discourse, The Square of the St. Blaise Church (Luza Square) and the Gunduliceva Poljana Square in the Old City of Dubrovnik, are analyzed and reflected upon through various data collection, theory reflections and urban design evaluation methods, such as Garham's Sense of Place Typology-Taxonomy.

If cities have livable and vibrant social spaces, do residents tend to have a stronger sense of community and sense of place? If such places are lacking, does the opposite happen?. This paper seeks out to answer these questions. Finally the paper also looks at how the phenomenon of creating good social spaces through creating ‘third places’ is achieved and confirmed in the squares of Dubrovnik.
Coping with the Politics of Renewal Insights from a Case Study of Whitefield, Nelson
Authors: Webb David
Published: January 2021

This article is an exploration of how power has been exercised over the future of part of a rural town in Lancashire, North West England. The article reviews a decade of debates about what should be done with the area, and draws loose comparisons between practices at various stages of the story and three conceptual frameworks from planning theory. The stages are likened to the theories of rational-comprehensive planning, agonism and communicative planning. This story is characterised by the attempts of spatially or deliberatively remote actors to define the area's future, and to justify this by recourse to one or more master narratives. The article appraises how successful each of the three planning theories have been at regulating these attempts to impose the area's future. It builds on existing critiques of rational planning and communicative planning and shows how, in this instance; well resourced agonistic debate was more effective at promoting the importance of disparate values and non-expert knowledge.
Applying Eco-Features of Traditional Vietnamese Houses to Contemporary High-Rise Housing
Authors: Hong Na Le Thi , Park Jin-Ho
Published: January 2021

This paper focuses on the potential applications of eco-features in Vietnamese traditional folk houses to contemporary high-rise housing. One of the main characteristics of traditional folk houses is that they are designed with a deep understanding of and respect for nature. This type of housing also expresses the way of life of its users, having evolved over generations while adapting to their needs, culture, and environment. Whereas the traditional Vietnamese houses can be an important source in the creation of a Vietnamese architectural identity, the design-with-nature approach and its unique characteristics are, however, scarcely found in the contemporary high-rise housing in Vietnam.

The objective of this research is to investigate the potential applications of eco-features in Vietnamese traditional folk houses to contemporary high-rise urban housing. Initially, this study examines the unique spatial characteristics of the traditional folk houses typical in northern Vietnam. In particular, four houses at the Duong Lam Village in northern Vietnam are reviewed. Some of the ecological design elements are extracted from the spatial composition of the typical Vietnamese folk houses in relation to the local climate conditions and the Vietnamese lifestyle (vernacular culture). Finally, this paper attempts to develop new housing models in urban Vietnam, employing the ecological elements learned from the preceding assessment.

Published: January 2021

Homeownership is a problem among younger working households (YWH). This is a more serious problem with YWH working in urban areas. New housing schemes introduced by the government show that measures are being taken. This paper aims to determine homeownership problems among YWH in order to assess the new housing schemes towards helping YWH. The questions arise are what are the homeownership problems among YWH and to what extent does YWH perceive the new housing schemes to help them. The objectives are to ascertain homeownership problems among YWH and to explore the perceptions of YWH on the new housing schemes introduced. The study was conducted qualitatively through in-depth interviews with YWH. The findings showed that the main homeownership problem highlighted by the YWH is housing prices are high in urban area which resulted to the location of affordable houses inconvenient. From the assessment, majority of the YWH agree with the new housing schemes. However there are weaknesses such as high land prices and absence of financial literacy. In conclusion, housing schemes should also consider financial education as part of their aims. Nevertheless, the introduction of housing schemes is beneficial to address homeownership problems among YWH.

Authors: Ebrahimi Mahdokht , Rahman Hamzah Abdul , Mohd-Rahim Faizul Azli , Chen Wang
Published: January 2021

In Malaysia, there are a few numbers of frameworks and checklists in order to evaluate the sustainable performance of buildings. In addition, most of these assessment frameworks or checklists focus on environmental sustainability disregarding social and economic pillars. The research in social and economic sustainability in the construction industry is pushing forward, albeit at a slow pace. In addition, the growing number of sustainable criteria in the literature highlights the importance of a systematic framework for construction initiatives. This research aims to propose a comprehensive framework based on three pillars of sustainability, and, additionally, to categorize them in a manner that is applicable for all relevant stakeholders based on their level of involvement and needs. Finally, it identifies the relation between each criterion and stage of the construction lifecycle with the assistance of an expert panel. This research produces a framework that is useful for Malaysian construction stakeholders to reinforce their approach towards sustainability through social and economic aspects that are currently underestimated in the construction industry.
Improving Communication and Changing Attitudes in Architectural Practices: Digital Architectural Education Tools for Non-Experts
Authors: Juvancic Matevz , Hocevar Marjan , Zupancic Tadeja
Published: January 2021

The persistence of difficulties related to communication of the stakeholders in the architectural and urban design process is mainly due to the diversity of interests, different perspectives, representation problems and the abilities of visual communication. The paper delves extensively into communication abilities and divides between experts and non-experts, exploring their epistemological origins and possible solutions. One of them, education about spatial issues for general public, is argued for and supported by in the form of a digital education tool. It builds on the idea that non-expert public should be approached with both: adaptation to its abilities and with additional teaching to improve these abilities. The experiment puts the prototypical architectural educational interface to the test in primary schools and observes the effect the level of interactivity has on learning outcomes. The results show possible ways of enhancing the efficiency of such tools and help developers and designers evaluate and fine-tune them for the process of non-professional architectural learning. The communication and attitude-changing topics are discussed from the specific architectural and from broader social science point of view.
Rwanda’s Urbanization Policy:- A Critical Reading
Authors: Somma Paola
Published: January 2021

If ever Africa had disappeared, it has now reappeared on the maps of investors seeking for land and resources. The entire continent seems to have become attractive for international financial institutions, which intensify their recommendations to single national Governments in order for them to further remove obstacles and make Africa an “ever better place to do business”.

Rwanda represents an emblematic example of the rapidity and size of transformations Africa is faced with, which touch every sector, from the land ownership model to the modes of land use, from the distribution of population, to the construction of infrastructure.

It is a fertile country, with a good water supply and two crop seasons, and is almost entirely cultivated. The majority of the inhabitants work the land, and subside thanks to agriculture. Today, however, the Government's goal, synthetically expressed in the slogan that defines the future of Rwanda as Africa's Singapore (Vesperini, 2010), is the modernization of agriculture, and the reduction of its weight in favour of a service economy. The most visible effects of this approach are the expulsion from the countryside of a huge number of families which lose any type of sustainment, and the grouping of many small plots in large territorial extensions which are often given for long term use to multinational agribusiness corporations. The transformation of agriculture is accompanied by the redistribution of population, traditionally settled in scattered patterns across the whole country. The massive migration from the countryside is explicitly sought by Government, whose target is to reach, by 2020, a 35% urbanization rate up from today's 18%.

The three issues, total and unconditional opening to foreign investment, population resettlement and transformation of the agricultural activities, which are the pillars of the development programs initiated by Government and international advisors, are producing dramatic changes on the physical and built environment, and affect the living conditions of the weakest groups (White, Borras, Hall, Scoones, Walford, 2012).

The paper proposes a reflection on themes which have general relevance, but which also need to be locally grounded. Of particular importance are urbanization, the relationship between towns and countryside, and the relationship between social and economic structure and territorial planning.

In 2012 the author took part as consultant to the drafting of the Urbanization sector strategic plan 2012-2017. The views expressed here are personal and do not in any way represent the Government or Institutions’ point of view.
Post-Disaster Housing: A Complex Systems Approach to Social Resilience
Authors: Elinwa Ugochukwu K. , Moyo Nothando
Published: January 2021

Conflicts are a form of man-made disaster changing the economy of nations, influencing energy concerns, food, shelter and demographic distributions. The breakdown of global systems has become a huge concern that needs working mechanisms to develop resilient cities. The working mechanisms vary from one country to another, thus making the process a complex reality. Resilience is a word that was derived from the Latin word “resalire” which means “to spring back”. In this work, the housing environment was considered as a system constituting of several subsystems (Social, Environmental, Political, Economic subsystems). It argues that for resilience to occur within the post-conflict housing environment there is a need for an inclusive evaluation of users' preferences and expectations. With a focus on the social subsystem, it tried to determine the level of significance of gender, age, income and level of exposure on the perceived social character of a post-conflict housing environment and the satisfaction derived thereof. The study showed the importance of inclusivity as it influences perception and satisfaction. Using regression analysis, the study revealed that Perception and satisfaction within a post-conflict housing environment were influenced by age (73%), gender (74%), income and level of exposure (54%).
Urban Transformations in the Culture of Santiago's Barrios
Authors: Maturana Beatriz , McInneny Anthony , Bravo Marcelo
Published: January 2021

Within Santiago, Chile's capital city, Barrio is a fundamental urban concept: an identity of place that defines a social space more than the territorial boundary of a designated area. Nearly 30 years of sustained, economic growth have positioned Chile, and Santiago with 40% of the country's population, as a tourist, financial and investment centre for South America. After a general decline of the inner-city area during the time of dictatorship (1973-1990), three inner-city residential barrios are being re-defined by their social and urban heritage as part of the “coolest” city of South America. These residential barrios possess the social characteristics of an urban unit within the concept of an ethical city—autonomy, conviviality, connectivity and diversity—and, in form and use, the basis of urban cultural tourism, a living heritage of residential architecture, public space and urban culture. The spatial and economic transformation of these barrios shifts the existing dynamic between the residents' social capital and the barrios' symbolic capital to the question of whose rights and interest should prevail. Through a literature review, policy review and an analysis of morphology and land use of three barrios, this article draws lessons to assist a re-thinking of the development of this urban, social-spatial unit of Chilean cities.
Unveiling contemporary dimensions in the internationalisation of family firms through bibliometric analysis and thematic analysis
Authors: Thukral Sonal , Jain Apoorva
Published: January 2021

Purpose

For sustaining a competitive advantage in the integrated world economy, it has become imperative for family firms to internationalise their operations in overseas markets. However, despite the growing set of literature, results are still inconclusive with respect to family firms’ internationalisation. Thus, this study aims to address this gap by systematically reviewing 142 articles (1991–2019) to help researchers in identifying and unfolding the unexplored themes in the underlying area.

Design/methodology/approach

For systematically reviewing articles, the study uses a three-step methodology following PRISMA guidelines, bibliometric analysis and thematic analysis. Descriptive statistics of 142 research articles are obtained through bibliometric analysis while thematic analysis is carried out to create themes or clusters of various factors relating to family firms’ internationalisation.

Findings

The current review uncovers the evolving trends in the research streams, most productive authors, top journals and articles, co-citation analysis, as well as the major themes surrounding the family firms’ internationalisation literature. Results from bibliometric analysis indicate that family firms’ internationalisation is an upcoming research area. Also, the review indicates an opportunity for scholars from developing nations to make significant contributions in the underlying research stream.

Research limitations/implications

Results from bibliometric and thematic analysis will help academicians and researchers in accumulating a holistic understanding relating to family firms’ internationalisation and understanding the upcoming trends in family firms’ research, thereby guiding the future research scope. Also, it will assist the family firms’ leaders and managers in understanding the important dynamics in overseas markets and various factors to be considered while planning their internationalisation.

Originality/value

Undertaking a systematic literature review presents readers with a state-of-the-art understanding of the underlying research topic. To the best of the knowledge, to date, the study is the first to conduct the review of literature through bibliometric analysis with the help of R Studio software in the field of family firms’ internationalisation. Also, the study is the first to review more than 100 research articles in the underlying area. Finally, the study proposes a comprehensive framework integrating the major themes and facets relating to family firms’ internationalisation.
Conditional stock liquidity premium: is Warsaw stock exchange different?
Authors: Stereńczak Szymon
Published: January 2021

Purpose

This paper aims to empirically indicate the factors influencing stock liquidity premium (i.e. the relationship between liquidity and stock returns) in one of the leading European emerging markets, namely, the Polish one.

Design/methodology/approach

Various firms’ characteristics and market states are analysed as potentially affecting liquidity premiums in the Polish stock market. Stock returns are regressed on liquidity measures and panel models are used. Liquidity premium has been estimated in various subsamples.

Findings

The findings vividly contradict the common sense that liquidity premium raises during the periods of stress. Liquidity premium does not increase during bear markets, as investors lengthen the investment horizon when market liquidity decreases. Liquidity premium varies with the firm’s size, book-to-market value and stock risk, but these patterns seem to vanish during a bear market.

Originality/value

This is one of the first empirical papers considering conditional stock liquidity premium in an emerging market. Using a unique methodological design it is presented that liquidity premium in emerging markets behaves differently than in developed markets.
Information systems project team members: factors for high performance
Authors: Moura Isabel , Dominguez Caroline , Varajão João
Published: January 2021

Purpose

The main aim of this study is to contribute to the discussion on the factors that can influence the high performance of information systems (IS) project team members, from the individual perspective. This study also allows both IS project team members and their managers to have a thorough picture of high-performing project teams, helping them improve team design, management and performance in today's demanding business environment.

Design/methodology/approach

To address the research questions, the authors carried out an exploratory case study of a small-sized holding company and a qualitative analysis of the data.

Findings

Results show a set of perceived factors that can influence (facilitate/hinder) the high performance of IS project team members. “Proper reward systems” was the most mentioned facilitating factor. “Negative affectivity” and “Lack of competence” were the two most referred as hindering factors. Most of the perceived factors are classified in the literature as non-technical.

Originality/value

Besides being among the very few empirical studies consolidating knowledge on the high performance of IS project team members, this paper extends the authors' previous research (done at the team level) to the individual team member level (as opposed to the team or organizational levels). In spite of IS being a highly technical industry, this study came across mostly human-centered factors transversal to different professionals (IS and non-IS) involved in project teams.
Distribution Prediction of Middle‐deep Lacustrine Source Rocks in Eocene Wenchang Formation in the Kaiping Sag, Pearl Mouth Basin

Published: January 2021

Oil and gas shows are rich in drilling wells in Kaiping sag, however, large oilfield was still not found in this area. For a long time, it is thought that source rocks were developed in the middle‐deep lacustrine facies in the Eocene Wenchang Formation, while there is no source rocks that in middle‐deep lacustrine facies have been found in well. Thickness of Wenchang Formation is big and reservoirs with good properties could be found in this formation. Distribution and scale of source rock are significant for further direction of petroleum exploration. Distribution characterization of middle‐deep lacustrine facies is the base for source rock research. Based on the sedimentary background, fault activity rate, seismic response features, and seismic attributes were analyzed. No limited classification method and multi‐attributes neural network deep learning method were used for predicting of source rock distribution in Wenchang Formation. It is found that during the deposition of lower Wenchang Formation, activity rate of main fault controlling the subsag sedimentation was bigger than 100 m/Ma, which formed development background for middle‐deep lacustrine facies. Compared with the seismic response of middle‐deep lacustrine source rocks developed in Zhu I depression, those in Kaiping sag are characterized in low frequency and good continuity. Through RGB frequency decomposition, areas with low frequency are main distribution parts for middle‐deep lacustrine facies. Dominant frequency, instantaneous frequency, and coherency attributes of seismic could be used in no limited classification method for further identification of middle‐deep lacustrine facies. Based on the limitation of geology knowledge, multi‐attributes of seismic were analyzed through neural network deep learning method. Distribution of middle‐deep lacustrine facies in the fourth member of Wenchang Formation is oriented from west to east and is the largest. Square of the middle‐deep lacustrine facies in that member is 154 km2and the volume is 50 km3. Achievements could be bases for hydrocarbon accumulation study and for exploration target optimization in Kaiping sag.
Experimental Study on Water‐rock Reactions with CO2 Fluid in a Deep Sandstone Formation under High Temperature and Pressure

Published: January 2021

Qiongdongnan Basin has a tectonic geological background of high temperature and high pressure in a deep reservoir setting, with mantle‐derived CO2. A water‐rock reaction device was used under high temperature and high pressure conditions, in conjunction with scanning electron microscope (SEM) observations, to carry out an experimental study of the diagenetic reaction between sandstone at depth and CO2‐rich fluid, which is of great significance for revealing the dissolution of deep clastic rock reservoirs and the developmental mechanism of secondary pores, promoting deep oil and gas exploration.

In this study, the experimental scheme of the water‐rock reaction system was designed according to the parameters of the diagenetic background of the deep sandstone reservoir in the Qiongdongnan Basin. Three groups of single mineral samples were prepared in this experiment, including K‐feldspar samples, albite samples and calcite samples. Using CO2 as a reaction solution, a series of diagenetic reaction simulation experiments were carried out in a semi‐closed high temperature and high pressure simulation system. A field emission scanning electron microscope (SEM) was used to observe the microscopic appearance of the mineral samples after the water‐rock reaction, the characteristics of dissolution under high temperature and high pressure, as well as the development of secondary pores.

The experimental results showed that the CO2‐rich fluid has an obvious dissolution effect on K‐feldspar, albite and calcite under high temperature and high pressure. For the three minerals, the main temperature and pressure window for dissolution ranged from 150°C to 300°C and 45 MPa to 60 MPa. Scanning electron microscope observations revealed that the dissolution effect of K‐feldspar is most obvious under conditions of 150°C and 45 MPa, in contrast to conditions of 200°C and 50 MPa for albite and calcite. Through the comparative analysis of experimental conditions and procedures, a coupling effect occurred between the temperature and pressure change and the dissolution strength of K‐feldspar, albite and calcite. Under high temperature and high pressure, pressure changed the solubility of CO2, furthermore, the dissolution effect and strength of the sandstone components were also affected. The experiment revealed that high temperature and high pressure conditions with CO2‐rich fluid has a significant dissolution effect on aluminosilicate minerals and is conducive to the formation of secondary pores and effective reservoirs. Going forward with the above understanding has important implications for the promotion of deep oil and gas exploration.

According to the hydrochemical characteristics, hydrogen and oxygen isotope characteristics and the ratio of noble gas isotopes of the sandstone aquifer and basalt aquifer, this study calculated the recharge temperature and residence time of groundwater in the Weishan area of Wudalianchi, also calculating the contribution of noble gas components from different sources to the samples. Based on the characteristics of hydrogen and oxygen isotopes and noble gases Xe and Ne, the recharge altitude and recharge temperature of the two aquifers were estimated, and the recharge temperature fitting with the NGT model as verified, the results showing that the main recharge altitude of groundwater in the region was 500–600 m, the recharge temperature being 2–7°C. Heeq and Heea of the samples have been simulated using the OD model, the content of radioactive 4He in the crust being obtained, the groundwater ages under the two conditions (closed condition and open condition) both being simulated. The results show that groundwater from the sandstone layer water is older than groundwater from the basalt layer. Hydrochemical characteristics and noble gas isotope ratios indicate that in the basalt aquifer and sandstone aquifer in the Weishan area, in addition to atmospheric and crustal helium, there is also an input of mantle‐derived helium. The fault constitutes the uplift channel for groundwater containings mantle components, which results in the mantle source composition in water samples near the fault being much higher than those form non‐fault areas.

This paper aims to apprehend evolution of ceramic manufacture strategy in the Johnston‐Vieillard manufactory (Bordeaux, France), which produced white earthenwares between 1835 and 1895. Glazes of fragments of 76 sherds, dated from different periods of the 19th century and found in excavations were characterised thanks to combined chemical and mechanical analysis. A comparative study was carried out for the determination of boron content in glazes by LA‐ICP‐MS and ion‐beam analyses (PIGE). In addition, an innovative study of the mechanical characteristics of the glazes by nanoindentation experiments was carried out in order to see whether or not the evolution of the glaze recipes was accompanied by an evolution of their mechanical properties.
Validation of PSI/PORT, CURB‐65 and SCAP scoring system in COVID‐19 pneumonia for prediction of disease severity and 14‐day mortality

Published: January 2021

Background

The unprecedented COVID‐19 pandemic has put a serious burden on the healthcare system worldwide. Due to varied manifestations of SARS‐CoV‐2 infection, many scoring systems, which were earlier used for community acquired pneumonia (CAP) are in use to determine the disease severity and the need of ICU admissions for proper management. COVID‐19 is a relatively new disease and the validity of these scoring systems in SARS‐CoV‐2 infection is not completely known. This study aimed to validate these scoring systems in cases of COVID‐19 pneumonia in an Indian setup. The study has also tried to find the most accurate indicator of disease severity and 14‐day mortality among these scoring systems.

Materials and Methods

This study included 122 SARS‐CoV‐2 infected patients at a tertiary hospital in Ranchi, Jharkhand. The severity of the disease according to ICMR protocol for COVID‐19, the PSI/PORT score, the CURB‐65 score and the SCAP score were calculated in all the patients and analysed with the disease outcome, that is, 14‐day mortality.

Results

SCAP score, PSI/PORT score and CURB‐65 criteria, all were good indicators of disease severity and 14‐day mortality. However, when compared to other scoring systems, SCAP score was a more accurate marker of disease severity and 14‐day mortality.

Conclusion

The PSI/PORT scoring system, the CURB‐65 criteria and the SCAP scoring system can be used to assess the COVID‐19 severity and predict the 14‐day mortality risk in cases of COVID‐19 pneumonia.
Multifaceted remodelling of cAMP microdomains driven by different aetiologies of heart failure
Authors: De Jong Kirstie A. , Nikolaev Viacheslav O.
Published: January 2021

Heart failure with preserved ejection fraction (HFpEF) will soon take over as the predominant form of heart failure. This is largely driven by the continuing increased incidences of obesity and type 2 diabetes (T2D), which promote HFpEF in the absence of pressure overload stresses. With beta‐blockers showing little effectiveness in treating obesity/T2D HFpEF and with no HFpEF‐targeted drugs currently available, we are in urgent need of a better understanding of how obesity/T2D HFpEF develops and how we may treat this condition. An exciting emerging field aiming to do this focuses on the investigation of 3',5'‐cyclic adenosine monophosphate (cAMP) microdomains in the heart. The previous work has largely focused on the investigation of cAMP microdomain remodelling in heart failure with reduced ejection fraction (HFrEF), with this work uncovering potential new targets for intervention strategies that otherwise would have been overlooked when studying changes in cAMP dynamics at the whole‐cell level. In this review, we aimed to discuss current advancements in our understanding of cAMP microdomain remodelling in HFrEF vs that in obesity/T2D‐associated HFpEF, with particular focus on the unresolved questions and limitations we face in being able to translate this knowledge.
