Opis:: The COVID-19 pandemic, caused by the SARS-CoV-2 virus, began in China in December 2019. The World Health Organization (WHO) declared it a pandemic on March 11, 2020. In Mexico, the first cases were registered in February 2020. On December 31st, 2021, three epidemic waves or peaks were registered, when some cases and deaths had a differentiated space-time behavior in the national territory, in which comorbidities, as one of the socio-spatial conditioning factors, also had an influence. The objective of this work is to analyze morbidity and mortality due to SARS-CoV-2, caused by the COVID-19 disease, with obesity comorbidities: high blood pressure, diabetes, obesity, and cardiovascular disease, accumulated from the years 2020 and 2021. Methodology. For this research, a literature review was carried out on the role of comorbidities in deaths from COVID-19. The universe of study is Mexico. The spatial disaggregation scale is atthe level ofthe federal entity or state-owned, with 32 spots. The sources of information are the Daily Technical Communications of the COVID-19 from the Government of Mexico; the Ministry of Health; the General Directorate of Epidemiology (DGE); information from the National Institute of Statistics and Geography (INEG), as well as information from the Geosalud México site. The analysis methods are the implementation of a geographic database, at the state-owned level, from which tables, maps and the generation of indicators (absolute values, percentages and ratio) were prepared, as well as thematic cartography using GIS software.

Opis:: The aim of this study was to determine the content of phosphorus and nitrogen in the bottom sediments of the Poraj Reservoir located on the Warta River, along with defining their spatial distribution and the relationship between these elements and organic matter, aluminum and iron. Samples of bottom sediments were collected on the basis of regular measurement grid of 46 points located in the area of the water reservoir Poraj. The collected samples were analyzed in terms of content of following elements, which values are in range: total phosphorus (TP) 0.06 – 5.06 g/kg, total nitrogen (TN) 0.17 – 9.66 g/kg, organic matter (OM) 0.49 – 28.41% of solid content, aluminum (Al) 2.44 – 145.15 g/kg and iron (Fe) 0.28 – 16.50 g/kg. By using of GIS system, spatial distribution of obtained results of laboratory analyzes were interpolated (Inverse Distance Weighted method was used). On basis of spatial distribution it was noted that in northern part of water reservoir bottom sediments have greater values of TP, TN and OM than in southern part. The study also included calculation of correlation between: OM and TN (n=46, R² = 0.9335), TN and Fe (n=46, R² = 0.8782), TN and Al (n=46, R² = 0.8629), OM and Fe (n=46, R² = 0.8243), OM and Al (n=46, R² = 0.7981), TP and Fe (n=46, R² = 0.7456), TP and Al (n=46, R² = 0.6209). The presented pilot studies show that the potential content of phosphorus, nitrogen and organic matter in the sediments of the water reservoir Poraj can reach a significant level. The need to plan and carry out further research allowing the evaluation of the properties of the analyzed elements and examining their potential impact on water quality in the tested water reservoir was stated.

Opis:: The creative sector is one of the most rapidly growing sectors of the global economy. This sector can also play an important role in providing economic benefits for developing countries. Promoting the creative economy needs a better understanding of the underlying factors that account for its spatial distribution. One of the most important factors that may influence the development of creative industries is tolerance. This paper focuses on the spatial distribution of the creative economy across cities in Indonesia and examines its relationship with tolerance. The main data sources of this paper are the unique data produced by the Central Bureau of Statistics (Badan Pusat Statistik or BPS) and the Indonesian Agency for Creative Economy (Badan Ekonomi Kreatif or BEKRAF), in addition to the City Tolerance Index provided by the SETARA Institute. The study finds that the creative economy in Indonesia does not tend to have a high spatial concentration, indicating that cities in Indonesia have an opportunity to develop the creative economy. The analysis confirms that tolerance matters for the creation of the creative economy in Indonesia. Three components of the City Tolerance Index that influence the creative economy are the Mid-Term Regional Development Plan, discriminatory regional rules and incidents of abuses against the freedom of religion or belief. The size of the population, the Human Development Index, and the status of a city as the provincial capital play a significant role in explaining the distribution of creative economies across the cities in Indonesia.

Tytuł:: Response to an anthropogenic acoustic stimulus in the terrestrial isopod Porcellio laevis Latreille, 1804 (Isopoda: Oniscidea: Porcellionidae)
Autorzy:: Vidal Franco, Pablo
Opis:: Anthropogenic acoustic pollution has an impact on the physiology of many organisms. Such pollution can have an effect on the encoding and decoding communication, which could cause disruptions in fragile ecosystems. A constant source of anthropogenic acoustic pollution could modify the physiology that allows species to interact with the environment or by triggering an inappropriate behavioural response. The behavioural alteration of a terrestrial isopod, Porcellio laevis Latreille, 1804, when exposed to acoustic pollution was studied. The control group was not exposed to acoustic sweeps, whereas the test group was exposed to a sinusoidal sweep (50–400 Hz) of one second looped to last one full minute. A camera was used to record the behaviour and the software TRex was used to analyze the isopods’ paths and collect speed information. Their distribution in regards to the source of the acoustic stimulus was analyzed, their overall motility (in cm) and their speed (in cm s$^{–1}$) were compared. The results of a dependent t-test and two independent t-tests suggest that when exposed to the stimulus, the isopods tried to avoid the acoustic stimulus and walk less distances, but without changes in speed.

Opis:: Various activities such as farming, industry, household waste, fish pond, and fishery can possibly affect the estuarine and coastal ecosystem. Demak waters, located to the east of Tanjung Emas Semarang, become an influential element of fishery industry that mostly produces anchovies and shrimps. This research was aimed at (1) analyzing the spatial distribution of heavy metal Pb and Cd in the surface water and sediment; and (2) investigating the abundance of coliform in Demak waters. Moreover, in this research, water pollution index was also analyzed and compared to other polluted water areas. It was found that the Pb content ranged from 0.6037 to 0.6647 mg·1^–1 whereas the Cd content ranged from 0.064 to 0.1707 mg·1^–1. Both lead and cadmium contents had surpassed the water quality standard. The Pb content in sediment ranged from 0.563 to 0.6823 mg·kg^-1 whereas the Cd content reached 0.0047 to 0.0577 mg·kg^-1. It showed that this sediment was not polluted by Pb and Cd. The analysis of water pollution index revealed that the pollution level found in Morosari, Rejo, Tuntang, and Lohbener estuary was low. On the other hand, Wedung and Serang estuary were heavily polluted. Compared to some previous studies, most of Pb and Cd contents in Demak waters were greater. However, lead and cadmium content in sediment was lower.

Opis:: This study deals with the development of industry which is one of the most important elements of socio-economic transformation in Turkey, its structural features, spatial distribution, as well as the factors that influence it. Industrialization movements started in Turkey in 1963 with planned development moves and accelerated as a result of the impact of liberal policies implemented, in and after the year 1980. Initially, industrial activities concentrated in metropolitan areas and subsequently started to expand to other areas in the country, in time with a view on regional development as a result of factors such as development plans, applied initiative policies, current raw material resources and transport. However, there are still major disparities in the distribution of the manufacturing industry, enterprises, employees, exporting and importing within the country. In fact, according to data for 2014, 43.9% of manufacturing industrial enterprises and 47.4% of employees are concentrated in the Marmara Region. The Marmara Region is followed by the Central Anatolian Region with 13.8% and 15.3% and the Aegean Region with 14% and 15.2% in terms of manufacturing industrial enterprises and employees respectively. Furthermore, 69.7% of exports and 76.9% of imports are processed in the Marmara Region which is followed by 9.6% and 7.7% in the Aegean Region and 8.2% and 7.4% in the Central Anatolian Region respectively. In terms of provinces, industry is concentrated in Istanbul, Izmir, Ankara, Bursa, Konya, Gaziantep, Antalya, Adana, Kocaeli and Denizli in Turkey. These provinces consist of 64% of enterprises and 65.7% of employees in Turkey. Data acquired from Turkish Statistical Institute (Turkstat) and the Ministry of Science, Industry and Technology has been assessed with the use of ArcGis program.

Opis:: Four soil profiles were collected from locations with different distances (5, 50, 250 and 1000 m) from a uranium mill tailings dam, Guangdong province, China, to investigate the pollution status of the soil in mining/ milling-related areas based on the contents of uranium (U) and thorium (Th), thus to understand the impacts of uranium industrial activities to the surroundings. The U and Th concentrations were determined by inductively coupled plasma mass spectrometry (ICP-MS) after conventional HF-HNO3-HClO4 digestion procedures. The results indicate that the soils within 50 m from uranium tailing were severely contaminated; those in 250 and 1000 m soil samples were observed to be with local background level even though these in 250 m had slightly higher U/Th ratios. Uranium concentrations varied from 5.50 ± 0.27 to 160.55 ± 8.03 mg/kg, with maximum values recorded in an intermediate layer of the 5-m distance soil profile. In comparison, the concentration of Th ranged from 6.02 ± 0.30 to 84.71 ± 4.24 mg/kg, with maximum values observed in the top layer of the 1000-m distance soil profile. The U/Th ratio varied from 0.15 to 11.99 compared with 0.20, 0.22 and 0.26 of the average for Guangdong province, national China and the world, respectively. The mean U/Th of four soil profiles showed a reduction with distance from the uranium mill tailing dam, suggesting the relatively large magnitude of uranium elevation in soils within limited distances.

Opis:: The aim of this study was to assess the spatial distributions of total trace elements content in the bottom sediments of Dzierżno Duże water reservoir, along with the comparison of the accuracy and characteristics of Kriging and IDW interpolations. On the basis of regular measurement grid consisting of 53 points, bottom sediments samples were collected. Mean values of total trace elements content in bottom sediments of Dzierżno Duże were as follows: Zn – 410 mg/kg, Pb – 57 mg/kg, Cr – 36 mg/kg, Cu – 40 mg/kg, Cd – 5 mg/kg, Ni – 16 mg/kg and Ba – 267 mg/kg. According to the geochemical quality classification, the concentrations of Cd in 32% of samples were assigned to class IV (heavily contaminated), 45% to class III (contaminated), Zn in 42% samples to class III with 1 sample in class IV and 26% to class II (slightly contaminated), Pb in 9% to class III and 58% to class II, Cu in 4% to class III and 68% to class II, Cr in 17% to class II, Ni in 55% to class II, Ba in 8% to class III and 61% in class II. Coefficient of determination was determined between each case of trace elements content. The highest correlation (R2 in range from 0.81 to 0.96) was observed between Zn and Pb, Zn and Cu, Zn and Cr, Zn and Ni, Pb and Cu, Pb and Cr, Cu and Cr, Cr and Ni. Significant correlation (R2 in range from 0.70 to 0.80) occurred between: Zn and Cd, Pb and Ni, Cu and Ni, Cd and Ni. The lowest correlations (R2 in range from 0.25 to 0.70) were observed between concentration of Ba and the rest of trace elements. Two different interpolation methods were chosen for the purpose of generating spatial distributions – Inverse Distance Weighted and Ordinary Kriging. These methods were chosen for purpose of obtaining optimal accuracy result of spatial distributions. The distributions of trace elements content were classified by means of geochemical criteria. In the case of accuracy comparison between IDW and Ordinary Kriging, the former had slightly better results in terms of mean value and root mean square. The generated spatial distributions allowed to determine the most contaminated areas, which were mainly northern-central and southern-central parts of water Dzierżno Duże reservoir.

Opis:: This data article aimed to evaluate the influencing mechanisms of the nutrients and the level of eutrophication in the Yangtze River estuary. The seasonal characteristics of nutrients (dissolved inorganic nitrogen (DIN), SiO3-2–Si, and PO43-P) in the seawater of the Yangtze River estuary were analyzed by conducting surveys in spring and summer of 2019. The findings revealed that the concentrations of all nutrient at the surface and bottom layers were lower in spring compared to summer. NO3–N was typically the major form of DIN. Runoff was identified as the primary source of DIN and SiO32−–Si, while PO43−–P originated from a various sources. The SiO32−–Si, while PO43−–P values in the surface and bottom layers during the spring and summer were higher than the Redfield values, indicating an imbalanced nutrient distribution. Furthermore, discrepancies were observed in the distributions of DIN/PO43−–P, SiO32−–Si/DIN, and SiO32−–Si/PO43−–P in the Yangtze River estuary. Through an examination of the ratio of DIN/PO43−–P absorbed by phytoplankton, PO43−–P was identified as a potential limiting factor for nutrition in the sea area of the Yangtze River estuary during spring and summer. The Eutrophication Index (E) values for both spring and summer were found to be higher than the eutrophication threshold, indicating severe eutrophication in the studied sea area.
