“We are a territory, a territory of struggles”: Community and Resistance Tourism in a Territorial Museum on the Outskirts of São Paulo

Summary The case presents an interpretation of the actions of valorization of cultural heritage mobilized by the political-cultural collective Comunidade Cultural Quilombaque. Active in the neighborhood of Perus, in the north-western part of the municipality of São Paulo, since 2005, Quilombaque shows itself to be a pole of agglutination of several artistic and political manifestations and other groups in the territory. From the consolidation of the Territorial Museum Tekoa Jopo’i and the Queixadas Agency, they have elaborated a path of trails that go through the neighborhood’s heritage that is marginalized by public preservation policies. Semi-structured interviews were conducted with central agents of the movement, in addition to participant observation on community tourism trails. The symbolic mediation promoted by the Museum educators brings out narratives of struggle eclipsed by the official policies of cultural heritage. The keys of solidarity and sharing operate by allowing a horizontal use of the riches organized by the Territorial Museum. The action of the Quilombaque Cultural Community transits in a fleeting limit between tourism and resistance, its tourism shows not only the resistance of the territory but is also organized with the community in such a way as to resist the tendencies of predatory tourism. On the one hand, the visits amplify voices silenced by hegemonic narratives. On the other hand, the very conception and organization of the trails are done in opposition to other models of tourism and predatory development. Information © The Authors 2023

Urban Dendroflora of Dry Subtropics of the Northwestern Part of The Greater Caucasus on the Example of the City of Gelendzhik

The article presents the results of the analysis of the species composition of the dendroflora of the city of Gelendzhik. The research covered 20 hectares of tree plantations. The route method and the transect method were used. In total, 30 transects were laid with a width of 5-20 m and the total length was 22 km. The routes covered all biotopes of natural (natural forest plantations on the outskirts of the city) and anthropogenic habitats (boarding houses, house territories of private households, spontaneous vegetation of roadsides and wastelands). True census of all tree and shrub species was carried out on the transects. Special attention was paid to rare species for which renewal and undergrowth were taken into account. The arboreal flora of Gelendzhik is represented by 110 species, which belong to 75 genera and 35 families. The predominant part of the dendroflora is represented by angiosperms (82.7%) and gymnosperms (13.7%). The families of Rosaceae, Cupressaceae and Fabaceae are most widely represented in the dendroflora of the city's green spaces (44%). The analysis of the species composition on their share of participation showed that the native fraction of the dendroflora prevails over the cultural one, which indicates its species richness. The analysis of the geographical element of the wild-growing fraction showed the heterogeneity of the dendroflora, in the formation of which 15 geographical elements take part. The largest number of species in the studied dendroflora belongs to the ancient Mediterranean group of geoelements. The significant participation of the Mediterranean and Caucasian geoelements indicates a high degree of autochthonicity in the development of the dendroflora of the city of Gelendzhik. Phanerophytes predominate among the life forms, represented equally by mesophanerophytes, nanophanerophytes and microphanerophytes. It should also be emphasized the significant participation of adventitious tree species (15.4% of the aboriginal fraction). Most of the adventitious species are of North American origin. The leading place in the quantitative spectrum is occupied by rare Mediterranean species Pinus brutia var. pityusa (Stev) Silba) (21% of the total number of studied individuals), Prunus mahaleb (L.) Vassilcz.) (7%), Pistacia atlantica Desf. (2.1%), which reflects the specifics of the dendroflora of the city of Gelendzhik.

ПЕРСПЕКТИВНОСТЬ ПРИМЕНЕНИЯ БАКТЕРИЙ PSEUDOMONAS PROTEGENS DA1.2 ДЛЯ ПОВЫШЕНИЯ УРОЖАЙНОСТИ ЯРОВОЙ ПШЕНИЦЫ В УСЛОВИЯХ БАШКИРСКОГО ПРЕДУРАЛЬЯ

The data of 3-year field experience with soft spring wheat in the conditions of the Northern forest-steppe zone of the Republic of Bashkortostan are presented. Treatment with nanomet and chistalan herbicides led to a significant reduction in the number of weeds and a decrease in the threshold of their harmfulness, while herbicides had a pronounced negative effect on the physiological and biochemical processes of wheat plants. The positive effect of the introduction of Pseudomonas protegens DA1.2 bacteria together with herbicides was revealed due to a decrease in the content of MDA, an increase in the content of chlorophylls and nitrogen index, all this led to an increase in yield. According to field experiments, the yield for an average of 3 years was 37.9 c/ha, an increase in wheat productivity of 24.5% or more of the control was observed in variants of joint treatment with bacteria with the herbicides. The studied strain can be recommended for increasing yields and more effective use of herbicides in the conditions of the Urals of the north-western part of the Republic of Bashkortostan.

Evaluation of Groundwater Quality. Case Study: Seini City, Maramureș County, Romania

"In the present study, in was investigated the groundwater quality from several private wells located in Seini city, Maramureș County (northwestern part of Romania). The investigated quality parameters were pH, redox potential, electrical conductivity, total dissolved solids, salinity, dissolved ions and heavy metals. The analysis showed that some of the investigated wells had a high content of nitrate, ammonium, and heavy metals. The continuous consumption of water from these sources can be a real threat for consumers’ health. The inhabitants should limit as much as possible the usage of water from these wells for drinking purposes and they should use the water from the local distribution network. Keywords: ground water quality, drinking water, chemical quality parameters"

ILLYRIAN ISSUES IN THE ENGLISH-LANGUAGE STUDIES OF MARJETA ŠAŠEL KOS

The article provides a historiographical overview and analysis of specific English-language publications by contemporary Slovenian researcher Marjeta Šašel Kos on the Illyrian issue. Issues related to hypotheses about the origin of the Illyrians, significant events in their internal history, achievements in various fields of culture, and an objective assessment of their relationship with the Greco-Roman world form the basis for an in-depth study of the ancient population of the Western Balkans, Central and Southwestern Europe. The world of Illyrian tribes, who were inhabitants of the eastern coast of the Adriatic Sea, the northwestern part of the Balkan Peninsula, and the southeastern part of the Alpine region, was in close proximity to the borders of the spread of the Greco-Roman civilization and its culture. Numerous Illyrian tribes, formed in the northern and southern ethno-cultural zone of the Eastern Hallstatt, were among the oldest tribal formations in the barbarian world of Europe (Pax Barbaricum). The world of the Illyrian tribes was sought to be understood by the ancient Greeks, followed by the Romans. However, contacts between representatives of these two diametrically opposite worlds ended in confrontation and assimilation. After numerous and bloody clashes, the world of the Illyrians lost its identity, underwent powerful Hellenization and Romanization, and acquired signs of deep provinciality. Therefore, the article's author seeks to introduce the reader to the achievements of individual bright and talented representatives of contemporary Illyriology and popularize their scientific work. Marjeta Šašel Kos's scientific work is diverse and productive (several extensive and substantive monographs and more than 70 scientific articles). The Slovenian researcher bases her views on archaeological and epigraphic materials, information comparisons, and reasoned criticism of ancient historians and geographers. All of these trends pursue a particular goal: to overcome the stereotype of perceiving representatives of the tribal world of ancient Europe, which was shaped by Greco-Roman written tradition. The review of her English-language works on the Illyrian issue demonstrates that Slovenian and European Illyriology are actively developing, allowing us to get to know and understand the specifics of the historical development of the ancient Illyrians.

Influence of methane and other hydrocarbon gases on foraminifera and nematodes in the Northwestern part of the Black Sea

This study investigates the response of foraminifera and nematodes to different types of methane and other hydrocarbon gases (alkanes, alkins) in bottom sediments of the northwestern shelf and continental slope of the Black Sea. Foraminifera are represented by 39 species from six orders, 13 families, 24 genera. Nematoda are represented by 48 species from six orders, 17 families, 27 genera. Both groups of meiobenthos are characterized by impoverished simple diversity and abundance/density as well as by much smaller sizes of foraminiferal tests compared to those from areas not affected by hydrocarbon gases, indicating stressful conditions for their life in the study areas. Among foraminifera, calcareous hyaline taxa dominate, but agglutinated forms are present as well and occasionally play a dominant role. A significant number of the identified nematode species belong to the tyobiotic type from the families Comesomatidae and Linhomoidae. They are characterized by a long, thin body and a small or completely undeveloped oral cavity, indicating their feeding on small particles of sediment or bacteria. Nine groups of foraminifera and nematodes were identified according to their tolerance and sensitivity to methane (15 species), ethane (five species), propane (eight species), butane (10 species), pentane (11 species), ethylene (20 species), propylene (two species), acetylene (three species), and isobutylene (one species). This study provides evidence for the first time that different types of methane, its homologues, and other hydrocarbon gases affect the reproduction, diversity, abundance, and growth of foraminifera, as well as density and simple diversity of nematodes.

Variation in small mammal food resource niche metrics of Western Barn Owl (Tyto alba) at the nesting pair and local population level

Abstract In the present study, we investigated food resource niche parameters and the degree of specialization of two local Western Barn Owl (Tyto alba) populations in two different demographic phases as the crash (2015–2016) and outbreak (2019–2020) of the Common Vole (Microtus arvalis). The study was conducted in two parts of the Transdanubian region of Hungary, namely in Duna-Drava National Park (DDNP) in the southeastern part, and in Fertő-Hanság National Park (FHNP) in the north-western part. For the analysis, we used food consumption data of 20–20 randomly selected breeding pairs from the DDNP population, while 14 and 17 breeding pairs in FHNP population in the crash and outbreak periods, respectively. Since the small mammal consumption of owls represented 99.3% of the total number of individuals, only data of small mammals as main food resource were taken into account during the analysis. Based on a trait-based framework which taking into account the resemblance between resources, Rao’s quadratic entropy metrics was used to estimate the food resource niche breadth at local owl populations and the breeding pair level. The small mammal resource utilization of owls was dependent on populations. The niche breadth of DDNP population was significantly smaller than FHNP population. The estimated niche overlap at the individual level was significantly different between the two populations. The calculated value of specialization of barn owl populations was significantly higher in north-western than south-eastern population. The niche breadth of the owl population living in the DDNP was significantly higher during the crash period. In contrast, the estimated niche breadth of the population living in FHNP did not differ significantly between the two demographic phases. Based on our result, the applied trait-based framework of resource niche pattern analysis demonstrated that the differences of niche breadth were explored in more detail by this method between the local Barn Owl populations of different geographical region.

Uncovering the Distribution Zones of Uranium and Thorium in Bangka Island

Radioactive minerals, especially containing uranium and thorium, can be used as a core element of nuclear fuel. Bangka Island is located in The Southeast Asian Tin Belt where it has a large uranium and thorium potential. The purpose of this study is to delineate distribution zone of uranium and thorium in Bangka Island. The study methods consist of radiometric measurement and mapping, petrographic analysis, and mineralogical analysis of pan concentrate samples. Based on radiometric measurement, positive anomaly value of equivalent uranium (eU) is ranging from 5-15 ppm while of equivalent thorium (eTh) is ranging from 45-75 ppm. The result of petrographic analysis from several outcrops of Klabat Granite indicated that there are monazites found in several samples of Mangkol Granite and of Bebuluh Granite. Radioactive mineral indication also can be identified as pleochroic halo within biotite in samples of Pelangas Granite and Menumbing Granite. Based on the result of mineralogical analysis of pan concentrate samples, it was identified that monazites can be found in all samples. Monazites constitute the percentages ranging from 2.82-10.66 %. Zircon also can be identified with percentages ranging from 9.13-76.75 % while ilmenite and magnetite minerals have average percentages of 24.09 % and 5.97 %, respectively. Favorable zones can be delineated in outcrops of Klabat Granite, Ranggam Formation and alluvial deposits in northern, northwestern, northeastern, central, and southeastern parts of Bangka Island. The occurrences of monazites in those lithological units are the main factors of high radioactivity in Bangka Island. Based on petrographic and mineralogical composition, those granite bodies which are correlated with Klabat Granite are mostly associated with ilmenite series with S-Type granitic rocks.

Innovative approach for surveying slope stability in road infrastructure rehabilitation

The objectives of the repair, maintenance and rehabilitation of the road network in mountainous terrains focus on the study of the structural condition of the rock slopes. An innovative approach to structural mapping and analysis was implemented within the framework of a survey project for a road section of road II-35 Troyan-Karnare, known as “BEKLEMETO”. This section begins with a long and steep descent from the Beklemeto saddle (at 1,525.5 m above sea level), passes through numerous bends on the southern rocky slope of the mountain and after 22.7 km descends into the northwestern part of the Karlovska valley, to the village of Karnare (at 562 m above sea level). The study of the structural disturbance provides an opportunity to present the groups of joints that have developed intensively on the rock slopes passing near the Republic Road II-35 in the section between Beklemeto and Karnare. Over the years, these slopes have been subjected to weathering, erosion and collapse processes, which have led to changes in the physical and mechanical properties of the rocks forming the slopes. The technology of mobile ground laser scanning, which is a suitable method for covering the complex characteristics of the terrain, was chosen for the research. The implementation of this technology was carried out through an integrated complex. Using this method, a total of 18 representative sections within the road II-35 “BEKLEMETO” were studied, and the number of measured cracks exceeded 13,000. The total length of the researched sections is over 10,770 m. In processing, short cracks with a length of less than 0.8 m, which do not affect the structural disturbance of the rock formations, are excluded. These data and studies are essential for the planning of effective measures to maintain and rehabilitate road infrastructure in complex mountain conditions.

GEODYNAMIC REGIMES IN THE LAPTEV SEA REGION ACCORDING TO THE LATEST SEISMOLOGICAL DATA

The results of the analysis of focal mechanisms and the general distribution of earthquake epicenters in the Laptev Sea region were presented. For four groups of clusters of events with known focal mechanisms, the directions of the principal stress axes were calculated by the formal stress inversion method. The distributions of earthquake epicenters and crustal thickness were compared. It has been revealed that, according to seismological data, the prolongation of the extension axis of the Gakkel Ridge on the Laptev Sea shelf is currently located in the vicinity of the group of extension detachments, which is extended along the eastern boundary of the Anisin, Zarya, and Belkovsko-Svyatonossky rift chains. The older extension axis, located along the group detachments marking the eastern boundary of the Ust-Lena and Omoloy rift systems, and continuing the axis of the Gakkel Ridge, is currently much less active, realizing residual stresses near its intersection with the Khatanga-Lomonosov fault zone in the northwestern parts of the shelf and with the Lena-Taimyr zone of boundary uplifts – in the southwestern. Near the Lena delta extension axes are oriented along the Olenekskaya and Bykovskaya channels and the border of the Siberian Platform, forming the extension conditions in the eastern part and the strike-slip regime in the western part of the vicinity of the Lena delta.

Consumption of Cereals and Pulses in Tribal’s of North-Western Part in Nashik District, Maharashtra (India): Study With the Use of GIS

Nutrition depends on diet, which consists of various articles of food. Hence, balanced and nutritious food is the most important single factor in connection with attainment and maintenance of health [1]. An individual’s health is largely determined by nutrition, and it is determined by diet, which consists of a variety of food items. A total of 115 villages were chosen, and 23 villages from the list of (ITDP) villages were randomly chosen in each tehsil (administrative unite in India). By using a probability proportional to the size of the various tribes, a total of 10 households from each chosen village were covered. For this reason, households in each village were divided into groups based on tribe and the necessary numbers of households (HH) from each tribe were included in the survey. The total amount of share in terms of weightage of assuming food item was calculated and using the allocated weightage. As a result, eating a well-balanced and healthy diet is the single most significant element in achieving and maintaining good health of an individual depends largely on nutrition. Tribal populations are malnourished and as a result of food deficiencies, they are at risk of developing dietary deficiency diseases.

Impacts of Land Use/Land Cover Distributions on Permafrost Simulations on Tibetan Plateau

The Tibetan Plateau (TP) is distributed with large areas of permafrost, which have received increasing attention as the climate warms. Accurately modeling the extent of permafrost and permafrost changes is now an important challenge for climate change research and climate modeling in this region. Uncertainty in land use and land cover (LULC), which is important information characterizing surface conditions, directly affects the accuracy of the simulation of permafrost changes in land surface models. In order to investigate the effect of LULC uncertainty on permafrost simulation, we conducted simulation experiments on the TP using the Community Land Model, version 5 (CLM5) with five high-resolution LULC products in this study. Firstly, we evaluated the simulation results using shallow soil temperature data and deep borehole data at several sites. The results show that the model performs well in simulating shallow soil temperatures and deep soil temperature profiles. The effect of different land use products on the shallow soil temperature and deep soil temperature contours is not obvious due to the small differences in land use products at these sites. Although there is little difference in the simulating results of different land use products when compared to the permafrost distribution map, the differences are noticeable for the simulation of the active layer. Land cover had a greater impact on soil temperature simulations in regions with greater land use inconsistency, such as at the junction of bare soil and grassland in the northwestern part of the TP, as well as in the southeast region with complex topography. The main way in which this effect occurs is that land cover affects the net surface radiation, which in turn causes differences in soil temperature simulations. In addition, we discuss other factors affecting permafrost simulation results and point out that increasing the model plant function types as well as carefully selecting LULC products is one of the most important ways to improve the simulation performance of land-surface models in permafrost regions.

A Generative Phonology: Syllable Structure of Hajji Yemeni Arabic

This study deals with the syllable structure of Hajji Yemeni Arabic (HYA) in the light of Generative Phonology. Hajji Yemeni Arabic is a variation of Arabic spoken in the northwestern part of Yemen, which tries to elaborate and discuss the elements of syllable structure and possibilities of patterns of syllables in a term of consonants and vowels. The main aim of this study is to investigate the syllabification patterns of Hajji Yemeni Arabic, hereafter referred to as (HYA). Through qualitative phenomenology, this study analyzed the different syllabification patterns attested in Hajji Yemeni Arabic and a comprehensive analysis of the syllable shape within the framework of Generative Phonology. The findings of the study; Hajji Yemeni Arabic has five patterns of syllables: (monosyllabic, disyllabic, trisyllabic, tetrasyllabic and pentasyllabic). Hajji Yemeni Arabic prohibits initial consonant clusters, but consonant clusters are permitted in the coda position, and the maximum number of permitted consonants is two only. No vowel occurs word-initially, and every syllable must begin with one and only one consonant sound (simple onset). Hajji Yemeni Arabic has two kinds of syllables: open syllables, as in the syllable shapes /CV/ and /CV:/, while closed syllables, as in the syllable shapes /CVC/, /CV:CC/, /CV:C/ and /CVCC/.

Improving categorical and continuous accuracy of precipitation forecasts by integrating Empirical Quantile Mapping and Bernoulli-Gamma-Gaussian distribution

Statistical post-processing is a pivotal approach in enhancing the statistical accuracy and applicability of precipitation forecasts from numerical weather prediction models. The existing methods primarily focus on correcting errors in either categorical or quantitative aspects individually, failing to address both simultaneously. Furthermore, the benefits of post-processing in extending the effective lead time (ELT) have not been quantitatively examined. In this study, an integrated statistical post-processing method by combining the Empirical Quantile Mapping (EQM) and the Bernoulli-Gamma-Gaussian model (BGG) (EQM-BGG for short) is constructed, and a comprehensive accuracy metric for evaluating the ELT is also proposed. Taking the Bengbu Basin located in the upper and middle reaches of the Huai River Basin as the study area, the statistical post-processing using the three methods (EQM, BGG, EQM-BGG) is performed on the multi-model weighted integration forecast precipitation (MWIFP), which are derived from three numerical models, namely ECMWF, NCEP and CMA. The results demonstrate that the integration of EQM-BGG capitalizes on the combined strengths of EQM and BGG, facilitating a dual correction of categorical and quantitative errors. The forecast accuracy (FA) and mean absolute error (MAE) of the post-processed basin-average forecasts are enhanced by more than 10%, and the ELTs for both the entire basin and sub-basins are extended by 12–78 h. At the grid scale, EQM-BGG significantly reduces the decay rate of forecast accuracy and the expansion speed of low-accuracy regions as the lead time increases, the improvement of FAs and MAEs surpasses 10% and 20%, respectively, across all grids within the lead time of 96–102 h. Furthermore, certain grids in the northwestern part show an extension of ELTs by 18 to 54 h. These findings highlight that EQM-BGG significantly enhances both categorical and quantitative accuracy simultaneously, resulting in precipitation forecasts that exhibit greater reliability over longer lead times. This advancement enriches the methodologies for hydro-meteorological forecasts.

The North Ukrainian Dialect of Vyšneve in the East Slavic Context: Towards a Final Description (part 2)

Abstract This paper continues an article devoted to the linguistic description of the local dialect of Vyšneve, cf. DiG 30 (2022), 23–49. The present study, as previously mentioned, completes a piece of a more comprehensive dialectal and sociolinguistic research on the dialects spoken along the Ukrainian-Belarusian and, to a minor extent, Russian borders. This is a territorial segment located in the eastern Polissian macro region and, more precisely, in the north-western part of the Region of Černihiv (Ukraine). In this continuation, the analysed material describes basic verbal morphology, the ways of expressing modality, the most evident syntactic and lexical features of this local dialect.

Spatial and temporal patterns of scyphozoan jellyfish abundance and growth in Icelandic coastal waters – a climate change perspective

ABSTRACT Scyphozoan jellyfish in Icelandic waters have received limited attention, despite apparent recent increases in blooms and changes in the regional oceanographic setting. The objectives of this study were to describe the species composition, abundance, phenology, and growth of scyphomedusae around Iceland and explore changes by comparing our findings with reports from the 1930s. Specimens were collected with a Bongo net in five regions around Iceland in the spring, summer, and autumn of 2008. Three jellyfish species were collected in the study, Aurelia aurita, followed by Cyanea capillata, and C. lamarckii. In the western and northwestern parts of Iceland, A. aurita abundance was highest in spring and summer, whereas in the North and East, abundances were highest in autumn. Cyanea capillata was not encountered in the Southwest, but in the west, Northwest, and North. There, numbers were highest in spring, whereas in the East, abundance was highest in autumn. Clockwise coastal current dispersal and regional interconnectivity are indicated. Weight-specific growth rates varied between 7.0 and 8.5% d−1 for A. aurita and 11.1 and 15.7% d−1 for C. capillata and are comparable to rates from often food-limited ecosystems at temperate latitudes. Presented evidence suggests that ephyrae and small medusae appear earlier in the season and in previously (in the 1930s) not occupied regions, while some regions (Southwest for C. capillata) were not populated anymore.

Application of frequency selection and geoelectrical sounding methods for mapping of leachate’s pathways in an active dumpsite

Contamination of surrounding environments is one of the threats to the proper maintenance of municipal waste sites in developing nations. This study integrates natural electromagnetic (EM) field and geoelectrical sounding methods to assess the leachate’s pathways in the near-surface layers and groundwater system in and around an active dumpsite. Five natural EM traverses were obtained in varying orientations using PQWT-TC 150 model. Fifteen vertical electrical sounding (VES) data points were randomly occupied using SAS 4000 ABEM resistivity meter. The two techniques revealed some intercalations of conductive and resistive media in the study area. The conductive media are composed of mixtures of leachates into clay and groundwater units, thereby creating zones of very low electrical potential differences from the surface to a depth beyond 30 m. A zone of leachate-aquifer’s interphase exists between the third layer and the fourth layer. The directions of the fluid flow are in the S–N and SE–NW trends, which could be linked to the fault towards the northwestern part of the study area. The fluid dynamics, however, justified the reason for the thick conductive materials being mapped at the northwestern and northern parts of the study area.

Современное состояние запасов тихоокеанской трески в северо-западной части Берингова моря и перспективы ее промысла

The article presents data on the fishery and stock status of Pacific cod in the northwestern part of the Bering Sea for the period from 1968 to 2024. It is shown that the increase in commercial stocks of this species to an abnormally high level (1.1-1.6 million tons) was due to the warming of water masses in the north of the sea and the formation of an accessible food supply, which contributed to the emergence of several productive generations and determined a high level of fish migration from the eastern parts of the sea. The significant biomass of Pacific cod made it possible to increase its predicted and actual catches to 120.0 and 105.3 thousand tons, respectively. The process of cooling of the Bering Sea waters, which began in 2021, with a simultaneous increase in the area of the cold Laurentian spot, limiting the spread of cod aggregations to the north-west of the sea, the exit of numerous generations of 2011, 2017, 2018 from fishery and the lack of new productive generations led to a decrease in fish stocks and catches to the average long-term level. The ongoing processes in the population dynamics of Pacific cod in the northwestern Bering Sea and the accompanying consequences for the efficiency of its fishery must be taken into account when making specific management decisions regarding resource users of this species.
