The 15-Minute city concept emerged as a response to the hyper-motorized city. First popularized by the Mayor of Paris in 2020, 15-Minute City is an evolving concept that derived from its predecessors such as neighborhood-unit planning and walkable city. This paper explores the implementation of the 15-Minute City concept in city planning by using Singapore as the case study. In 2018, Singapore released its Land Transport Master Plan 2040 and which includes an ambitious concept of 20-Minute Towns and a 45-Minute City (2MT45MC) and has similar ideas to the 15-Minute City concept. Through various journal articles and media coverage, Singapore’s policy and regulation regarding its transport planning were thoroughly reviewed to find Singapore’s strategy and challenges in realizing the objective of its 2MT45MC concept. Normalizing active mobility and enhancing connectivity nationwide are the main strategies to overcome the biggest challenges faced: lack of legal backing in personal mobility devices and the country’s rigid zoning. Even though it is too early to say whether 2MT45MC is achievable or not, projects such as the North-South Corridor show that for a long-term plan, it seems feasible.

The paper summarizes the geodetic contribution for the Slovak team within the joint Polish-Slovak archaeological mission at Tell el-Retaba in Egypt. Surveying work at archaeological excavations is usually influenced by somewhat specific subject of study and extreme conditions, especially at the missions in the developing countries. The case study describes spatial data development according to the archaeological conventions in order to document spatial relationships between the objects in excavated trenches. The long-term sustainability of surveying work at the site has been ensured by detailed metadata recording. Except the trench mapping, Digital Elevation Model has been calculated for the study area and for the north-eastern part of the site, with promising preliminary results for further detection and modelling of archaeological structures. In general, topographic mapping together with modern technologies like Photogrammetry, Satellite Imagery, and Remote Sensing provide valuable data sources for spatial and statistical modelling of the sites; and the results offer a different perspective for the archaeological research.

Abstract The geological structure of the Bełchatów area is very complicated as a result of tectonic and sedimentation processes. The long-term exploitation of the Bełchatów field influenced the development of horizontal displacements. The variety of factors that have impact on the Bełchatów western slope stability conditions, forced the necessity of complex geotechnical monitoring. The geotechnical monitoring of the western slope was carried out with the use of slope inclinometers. From 2005 to 2013 fourteen slope inclinometers were installed, however, currently seven of them are in operation. The present analysis depicts inclinometers situated in the north part of the western slope, for which the largest deformations were registered. The results revealed that the horizontal displacements and formation of slip surfaces are related to complicated geological structure and intensive tectonic deformations in the area. Therefore, the influence of exploitation marked by changes in slope geometry was also noticeable.

Abstract Objective: To understand the repercussions of coexisting with the drug use in a family based on the daughter's narrative of a woman who is a multiple drugs user. Method: A case study with a family accessed in 2014, through the records of a Poison Control Center in the North of Paraná. It was used a semi-structured interview and field journal, and resources of thematic oral history to apprehend the story, from the question "How is/was for you and your family to live with a mother who is a drug user?” Results: The daughter's memories emphasized repercussions in the family context: long-term of living with drug abuse; absence or transience of the motherly figure, with rupture processes for homeless situation; cycle of parental disruption/forgiveness and continued presence and fatherly support. Final considerations: The narrative indicated a family that could be added to the process of rehabilitation and social reintegration of the female drug user.

AbstractThe catastrophic lahars triggered by the 13 November 1985 eruption of the ice-clad Nevado del Ruiz volcano, Colombia, demonstrate that the interaction of hot pyroclasts with snow and ice can release 30–50 millionm3 of meltwater in 30–90 minutes. The 1985 eruption caused a 16% loss in area and a 9% loss in volume of snow, firn and ice. Turbulent pyroclastic density currents mechanically mixed with snow and produced meltwater at a rate of 0.5–1.6mms–1. Laboratory experiments suggest that turbulent, fluidized pyroclastic density currents exert mechanical and thermal scour, thereby efficiently transferring heat from hot pyroclasts to snow. Ice cap loss at Nevado del Ruiz continued between 1985 and 2000, representing a ∽52% decline in area and a ∽30% fall in volume. Ice 60–190m thick caps the east and southeast summit plateau, whereas an ice field < 30m thick and devoid of snow is retreating on the north, northeast and west edges. This asymmetrical distribution of ice reflects combined long-term effects of the 1985 eruption and of the post-1985 ice cap retreat. Should volcanic activity resume, steep-sided glaciers can fail and pyroclastic flows and surges can sweep the snowpack and generate mixed avalanches and lahars. Although the potential source of meltwater has decreased since 1985, extensive debris at the ice cap margins can be incorporated to future lahars.

Abstract The channel of most of the rivers is the result of long-term human endeavour to modify their shape. This paper focuses on the flow of commodities juxtaposed with the physical water flow of the river that has served over centuries as one of the main means of goods transport. The topic is closely observed on the example of the Danube regulation in Bratislava at the end of the nineteenth century and the transformation of the river into a canal. The reasons for the individual interventions in the natural riverbed differed. The third regulation (1886 - 1896) was meant to add the missing part of the canal on the route between the North and Black Seas, which would be fully adapted for freight transport by steamer. The 19th century has introduced a new paradigm to city planning. In the belief in technical innovation, the planning process was undertaken by engineers. The paper places in confrontation the oeuvre of two engineers, Charles-Joseph Minard and Enea Grazioso Lanfranconi. While the former, a French civil engineer, brought a unique way of visualizing the flow of goods between territories based on statistical data, the latter, a Hungarian hydraulic engineer, is the author of the third regulation of the Danube in the section between Devín (Theben) and Gönyű (Gönyö). For the purpose of the paper, the original theoretical work of Enea Grazioso Lanfranconi was translated and analysed. Selected data from Lanfranconi’s work was interpreted visually.

Traditional cities emerged and grew according to the residents’ needs; thus they were a reflection of the community’s culture and traditions. But lately cities have witnessed numerous changes and challenges. Nasr City in Cairo was planned as a suburb in the late sixties to tackle the housing shortage in Cairo. Nasr city’s master plan aimed at accommodating modern planning concepts where it featured an abundance of open public spaces when compared to other districts of Cairo. However, these spaces are empty of people most of the time, which detracts from the character and the experiential qualities of the area. This paper aims to explore the way in which the residents of Nasr city envision ‘their’ public spaces, comprehending the reasons why their usage of such spaces is currently hindered and discovering their recommendations for enhancing public spaces in their neighbourhoods in a way that would encourage them to visit them regularly. In addition, this paper assesses Nasr city’s public spaces, in an attempt to bridge the gap between the offered built environment and people’s needs. This assessment shall be achieved through the use of questionnaires, observations of people’s reactions towards offered public spaces, urban surveys of the provided public spaces and interviews with officials. Based on these studies the paper proposes recommendations incorporating people’s needs for a vivid public realm, in order to help planners and officials to understand the malfunctions inherent in modern city planning and management models that have hindered planned public spaces from conveying and fulfilling their role as centres of social interaction.

Cyclic Variations

AbstractLong-term cyclic variations in the distribution of prominences and intensities of green (530.3 nm) and red (637.4 nm) coronal emission lines over solar cycles 18–23 are presented. Polar prominence branches will reach the poles at different epochs in cycle 23: the north branch at the beginning in 2002 and the south branch a year later (2003), respectively. The local maxima of intensities in the green line show both poleward- and equatorward-migrating branches. The poleward branches will reach the poles around cycle maxima like prominences, while the equatorward branches show a duration of 18 years and will end in cycle minima (2007). The red corona shows mostly equatorward branches. The possibility that these branches begin to develop at high latitudes in the preceding cycles cannot be excluded.

Purpose This study examined caregiver perceptions of their child's language and literacy disorder as influenced by communications with their speech-language pathologist. Method The participants were 12 caregivers of 10 school-aged children with language and literacy disorders. Employing qualitative methods, a collective case study approach was utilized in which the caregiver(s) of each child represented one case. The data came from semistructured interviews, codes emerged directly from the caregivers' responses during the interviews, and multiple coding passes using ATLAS.ti software were made until themes were evident. These themes were then further validated by conducting clinical file reviews and follow-up interviews with the caregivers. Results Caregivers' comments focused on the types of information received or not received, as well as the clarity of the information. This included information regarding their child's diagnosis, the long-term consequences of their child's disorder, and the connection between language and reading. Although caregivers were adept at describing their child's difficulties and therapy goals/objectives, their comments indicated that they struggled to understand their child's disorder in a way that was meaningful to them and their child. Conclusions The findings showed the value caregivers place on receiving clear and timely diagnostic information, as well as the complexity associated with caregivers' understanding of language and literacy disorders. The findings are discussed in terms of changes that could be made in clinical practice to better support children with language and literacy disorders and their families.
