This article investigates the problem of changing land uses in historical city centers, a problem which often leads to the alteration of their historical, architectural and functional physiognomy, as well as the loss of their inhabitants. It also discusses the importance of land management and proposes a multifunctional reuse model for sustainable development in abandoned or degraded areas in historic cities. This problem is found in historical centers nowadays, especially in the European South, and many theoretical texts and urban studies deal with the issue. Taking under consideration the case of the Historical “Commercial Triangle” of Athens, this article presents the results of an extensive field work, which led to the mapping and analysis of the neighborhood’s special identity. Subsequently, these results lead to the presentation of the problems caused by the dominating uses of recreation and tourism, which suppress the traditional existing commercial uses and the residency. It concludes by proposing preservation strategies for the reuse and development of the area and emphasizes the importance of a management plan aiming towards the preservation of the historical character of the commercial center and its sustainable development. The work presented in this paper is based on an assignment produced in 2020 for the purposes of the post-graduate course “Protection and Preservation of a historical urban center or settlement”, which is part of the post-graduate program “Protection of Monuments” in the School of Architecture, NTUA.

Abstract Diverse forests with distinct forest types, harbor exceptional biodiversity and provide many ecosystem goods and services, making some forest types more economically valuable and prone to exploitation than others. The high rates of deforestation in Southeast Asia endanger the existence of such vulnerable forest types. Myanmar, the region’s largest forest frontier provides a last opportunity to conserve these vulnerable forest types. However, the exact distribution and spatial extent of Myanmar’s forest types has not been well characterized. To address this research gap, we developed a national scale Forest Type map of Myanmar at 20m resolution, using moderate resolution, multi-sensor satellite images (Sentinel-1, Sentinel-2 and ALOS-PALSAR), extensive field data, and a machine learning model (RandomForest). We mapped nine major forest types and developed a Conservation Status Score to evaluate the conservation status of the mapped forest types. Swamp, Mangrove, Dry Deciduous, Lowland Evergreen and Thorn forests were ranked as the five least conserved forest types. We also identified the largest remaining patch for each of the five least conserved forest types and determined their protection status to inform future forest conservation policy. In most cases, these patches lay outside protected areas indicating areas that may be prioritized for future conservation.

Abstract Extensive field surveys were carried out to explore the distribution of Leisler’s Bat Nyctalus leisleri (Kuhl, 1819) in selected area of FATA regions, Pakistan. Specimens of Leisler’s Bat Nyctalus leisleri (Kuhl, 1819) (n5) were collected from Kurram Agency (Shublan) (N33.8229788 E70.1634414) at elevation 1427m and Khyber Agency (Landi Kotel) (N34.0909899 E71.1457517) at elevation 1091m for two years survey extending from May 2013 through August 2015. The mean head and body length, hind foot length, ear length and tail length the Nyctalus leisleri specimens captured from the study area was 65.08 ± 1.58 mm, 44.06 ± 0.52 mm, 8.38 ± 0.60 mm, 13.20 ± 0.99 mm and 39.46 ± 1.46 mm, respectively. For molecular analysis the sequences of COI gene were obtained and analyzed. The mean intraspecific divergences of Nyctalus leisleri was 0.04%. The mean interspecific divergences of Nyctalus noctula and Nyctalus leisleri was 0.2%. The mean concentration of each nucleotides was A = (26.3%), T = (32.8%), G = (15.9%) and C = (25.0%). The mean A+T contents were 59.2%and C+G were 40.9%. In the phylogenetic tree Nyctalus leisleri and Nyctalus noctula clustered with significant bootstrap support value.

Introduction. The article considers the variety and functions of dishes and utensils used at the sacrificial rituals of Trans-Kama “pagans” Udmurts from the Republic of Bashkortostan and Perm Krai. This is the first attempt of using extensive field and archival materials for the research purposes. Materials and Methods. The material for the study represents the published and archival sources, ethnographic information collected the authors during many years of field research. The analysis of materials was carried out using a comparative-historical method. The article takes into account the theoretical approaches of the semiotic school in ethnology. Results and Discussion. In the object world of Udmurt sacrifices, a special place is occupied by dishes and utensils. Without them the ritual process involving the preparation of food and a joint meal is impossible. Various dishes (cauldrons, troughs, buckets, bowls, spoons, ladles, etc.) are used for their utilitarian purpose (cooking, storage, transportation, eating food, etc.) but inclusion in the ritual process endows them with symbolic functions. Conclusion. Dishes and utensils used at the sacrifices of the Trans-Kama Udmurts are still endowed with a high sacred status. The number, composition and methods of using ritual utensils have remained traditional but their forms, material and manufacturing method have changed. As before, in addition to being used for utilitarian purposes they are endowed with many symbolic functions.

Abstract The rock slopes in the Indian Himalayan region are exposed to recurrent freeze-thaw. Freeze-thaw plays a dominant role in the instability of rock slopes in cold regions. Extensive field investigations have been carried on the two rock slopes of the Solang valley roadway in Himachal Pradesh. Freeze-thaw testing has been carried out in the laboratory on the rock samples collected from the studied slopes. The test has been repeated for 30 freeze-thaw cycles. The laboratory tests have been conducted to determine the mechanical properties of rock with and without freeze-thaw conditioning. The micro-photographs from scanning electron microscope have been obtained to identify the microscopic damages due to freeze-thaw activity. The macroscopic damages have been recognized in tensile, compressive and triaxial compressive strength of rock. Further, a three-dimensional numerical analysis has been performed to evaluate the stability and corroborate the results with the field observations. FT conditioning results reveal a reduction of about 27–39 % in rock strength and subsequently a decrease in the factor of safety by 10–39 % for rock slopes.

The cold chain is crucial to ensure the quality and effectiveness of transported and stored medicines. For this, it is necessary to carry out the thermal mapping of routes for drugs transported between 15°C and 30°C, so that the most assertive decision can be taken without raising costs. This study aims to identify the main factors influencing the thermal mapping of pharmaceutical products in the cold chain and applying the machine learning technique. The method used for this systematic review is the Prisma, where the identification, screening, eligibility, and inclusion stages were analyzed. After analyzing 75 articles, the result shows that only eight papers were consistent with the use of modeling in the medicine cold chain distribution. Thus, it can be concluded that there is an extensive field to be researched regarding the use of prediction algorithms in the cold chain of drugs and vaccines.

Abstract Laughter is not just an element in human communication that signifies happiness and enjoyment, it can be used as a communication strategy to lubricate successful interaction including business communication. Nonetheless, not many studies have paid attention to laughter in business communication. Therefore, this paper sheds light on how Thai and Burmese participants used laughter in a restaurant and in a business meeting in Yangon, Myanmar. Audio data was collected together with various pieces of ethnographic data, for example, participant observations reported from extensive field notes, semi-structured interviews and audio recordings. The analysis was based on the classification of laughter adopted from Hayakawa (2003), and Murata and Hori (2007). The findings reveal that laughter is deployed as a communication strategy with different purposes such as to make fun of work, to ease tension and to threaten other interlocutors and unveil those factors which stimulate the laughter in informal and formal settings.

Resurgent populism in East Central Europe is typically analyzed at the national level. This paper examines populist urban movements in two of the region’s capital cities: Prague and Warsaw. It locates the origin of urban populist grievances in the crisis of urban-planning regimes after communism. At the same time, it argues that the character of populist urban movements, in terms of their mobilizing frames and tactics, varies between cities depending on the openness of municipal institutions to new social actors. The research draws on extensive field interviews, policy documents, academic analyses, and domestic media reports. It sheds light on an under-studied variant of postcommunist populism—one less conservative and potentially more inclusive—and contributes to the literatures on postcommunist civil society, urban planning, and municipal-level politics.

Padre Island is the world’s longest barrier island and includes the longest stretch of undeveloped barrier island in the world. Largely due to harsh environmental conditions and difficult access, only cursory and incomplete checklists and subjective estimates of abundance have been produced. The results of an inventory of amphibians and reptiles of North Padre Island conducted 2002–2020, including the results of extensive field surveys conducted 2002–2003, are reported herein. Natural history museum and iNaturalist records are summarized and compared among North and South Padre and Mustang islands and the mainland portion of the seven counties in which the islands occur. The conservation status of rare species and extirpation of others is noted. The morphology and taxonomic status of some unique occurrences are discussed. Eleven species of amphibians and 39 species of reptiles presently occur or have occurred naturally or as introduced or accidental species on North Padre Island. Twelve species of amphibians and 50 species of reptiles occur or have occurred on North Padre, South Padre, and Mustang islands. Thirty-one species of amphibians and 93 species of reptiles have been reported from the seven counties in which the islands occur.

Abstract. The glacier-dammed Lac des Faverges, located on Glacier de la Plaine Morte (Swiss Alps), has drained annually as a glacier lake outburst flood since 2011. In 2018, the lake volume reached more than 2 × 106 m3, and the resulting flood caused damage to the infrastructure downstream. In 2019, a supraglacial channel was dug to artificially initiate a surface lake drainage, thus limiting the lake water volume and the corresponding hazard. The peak in lake discharge was successfully reduced by over 90 % compared to 2018. We conducted extensive field measurements of the lake-channel system during the 48 d drainage event of 2019 to characterize its hydraulics and thermodynamics. The derived Darcy–Weisbach friction factor, which characterizes the water flow resistance in the channel, ranges from 0.17 to 0.48. This broad range emphasizes the factor's variability and questions the choice of a constant friction factor in glacio-hydrological models. For the Nusselt number, which relates the channel-wall melt to the water temperature, we show that the classic, empirical Dittus–Boelter equation with the standard coefficients does not adequately represent our measurements, and we propose a suitable pair of coefficients to fit our observations. This hints at the need to continue research into how heat transfer at the ice–water interface is described in the context of glacial hydraulics.
